Newtons Law Of Motion Computer Science Essay
In this assignment, I will larn about the result two that is Newton ââ¬Ës jurisprudence and harmonic oscillation. Newton ââ¬Ës jurisprudence can be divide by three types that is 1st jurisprudence, 2nd jurisprudence and 3rd jurisprudence. It is teach about the gesture in our existent life. Thus, harmonic oscillation can be divided by three types that are pendulum oscillation, damped oscillation and mechanic oscillation. All of these oscillation are utile in our life especial is use in different type of mechanics.Question OneResearch on the Newton ââ¬Ës Laws of gesture, and do a study that provide item account and illustrations on Newton ââ¬Ës 3 Torahs of gesture. You report should include relevant and utile expression.AnswerNewton ââ¬Ës jurisprudence of gesture can be divided by three types that is 1st jurisprudence, 2nd jurisprudence and 3rd jurisprudence and it is jurisprudence of gravitation. The three Torahs are simple and reasonable. The first jurisprudence provinces that a force must be applied to an object in order to alter its speed. When the object ââ¬Ës speed is altering that average it is speed uping, which implies a relationship between force and acceleration. The 2nd jurisprudence, the acceration of an object is straight relative to the net force moving on it and is reciprocally relative to its mass. The way of the acceleration is in the way of the acceleration is in the way of the net force moving on the object. Finally, the 3rd Torahs, whenever we push on something, it pushes back with equal force in the opposite way.ForcesA force is normally imagined as a push or a pull on some object, possibly quickly, as when we hit a tennis ball with a racket. ( see figure 1.0 ) . We can hit the ball at different velocities and direct it ionto different parts of the oppositions ; s tribunal. This mean that we can command the magnitude of the applied force and alos its way, so force is a vector measure, merely like speed and acceleration. Figure 1.0: Tennis title-holder Rafael Nadal strikes the ball with his racket, using a force and directing the ball into the unfastened portion of the tribunal. Figure 1.1: Examples of forces applied to assorted objects. In each instance, a force acts on the object surrounded by the dotted lines. Something in the environment external to the boxed country exerts the force.Newton ââ¬Ës 1st jurisprudenceNewton ââ¬Ës 1st jurisprudence of gesture provinces that if a organic structure is at remainder it will stay at the remainder and if a organic structure is traveling in a consecutive line with unvarying speed will maintain traveling unless an external force is acted upon. For illustration, see a book lying on a tabular array. Obviously, the book remains at remainder if left entirely. Now imagine forcing the book with a horizontal force great plenty to get the better of the force of clash between the book and the tabular array, puting the book in gesture. Because the magnitude of the applied force exceeds the magnitude of the clash force, the book to a halt. Now imagine the book across a smooth floor. The book once more comes to rest one time the force is no longer applied, but non every bit rapidly as earlier. Finally, if the book is traveling on a horizontal frictionless surface, it continues to travel in a consecutive line with changeless speed until it hits a wall or some other obstructor. However, an object moving on a frictionless surface, it ââ¬Ës non the nature of an object to halt, one time set in gesture, but instead to continues in its original province of gesture. This attack was subsequently formalized as Newton ââ¬Ës first jurisprudence of gesture: An object moves with a speed that is changeless in magnitude and way, unless acted on by a nonzero net force. For illustration: In the figure 1.2, the twine is supplying centripetal force to travel the ball in a circle around 3600. If sudden the twine was break, the ball will travel off in a consecutive line and the gesture in the absence of the restraining force. This illustration is non hold other net forces are moving, such as horizontal gesture on a frictionless surface. Figure 1.2InactivenessInertia is the reluctance of an object to alter its province of gesture. This means if an object is at remainder it will stay at remainder or if it ââ¬Ës traveling it will maintain traveling in a consecutive line with unvarying speed. Force is needed to get the better of inactiveness.For illustrationIn figure 1.3, it is an experiment to turn out the construct of inactiveness. In experiments utilizing a brace of inclined planes confronting each other, Galileo observed that a ball would up the opposite plane to the same tallness and turn over down one plane. If smooth surface are used, the ball is roll up to the opposite plane and return to the original tallness. When it is get downing to turn over down the ball on the degree topographic point, it is will return the ball at the same tallness from original point. Figure 1.3 If the opposite slope were elevated at about a 0 grade angle, so the ball will be roll in an attempt to make the original tallness that is show in the figure 1.4. Figure 1.4: If a ball stops when it attains its original tallness, so this ball would ne'er halt. It would turn over everlastingly if clash were absent.Other illustrationFigure 1.5: Harmonizing to Newton ââ¬Ës 1st jurisprudence, a bikes gesture was n't alteration until same force, such as braking makes it alteration.Newton 2nd jurisprudenceNewton ââ¬Ës first jurisprudence explains what happens to an object that has no net force moving on it. The object either remains at remainder or continues traveling in a consecutive line with changeless velocity. Newton ââ¬Ës 2nd jurisprudence is the acceleration of an object is straight relative to the net force moving on it and is reciprocally relative to its mass. The way of the acceleration is in the way of the acceleration is in the way of the acceleration is in the way of the net force moving on the object. Imagine forcing a block of ice across a frictionless horizontal surface. When you exert some horizontal force on the block, it moves with an acceleration of the 2m/s2. If you apply a force twice every bit big, the acceleration doubles to 4m/s2. Pushing three times as difficult triples the acceleration, and so on. From such observations, we conclude that the acceleration of an object is straight relative to the net force moving on it. Mass besides affects acceleration. Suppose you stack indistinguishable block of ice on top of each other while forcing the stack with changeless force. If the force applied to one block produces an acceleration of 2m/s2, so the acceleration drops to half that value, 1 m/s2, When 2 blocks are pushed, to one-third the initial value. When three block is pushed, and so on. We conclude that the acceleration of an object is reciprocally relative to its mass. These observations are summarized in Newton ââ¬Ës 2nd jurisprudence: The acceleration of an object is straight relative to the net force moving on it and reciprocally relative to its mass.Unit of measurements of Force and MassThe SI unit of force is the Newton. When 1 Newton of force Acts of the Apostless on an object that has a mass of 1 kilograms, it produces an acceleration of 1 m/s2 in the object. From this definition and Newton ââ¬Ës 2nd jurisprudence, we can see that the Newton can be expressed in footings of the cardinal units of mass, length and clip. 1 N = 1 kg.m/s2 A force is a push or a pull. Hence a force can alter the size, form, and province of remainder or gesture, way of gesture and velocity / speed. The symbol for force is F and the S.I. unit is Newton ( N ) . An object of mass m is subjected to a force F, its speed alterations from U to V in clip t. The above status can be stated as: F = Where a = is acceleration, therefore F = mom.For illustrationFigure 1.6: An airboat. An airboat with mass 3.50x102Kg, including riders, has an engine that produces a net horizontal force of 7.70x102N, after accounting for forces of opposition ( see figure 1.6 ) . ( a ) Find the acceleration of the airboat. ( B ) Get downing from remainder, how long does it take the airboat to make a velocity of 12.0m/s2? ( degree Celsius ) After making this velocity, the pilot turns off the engine and impetuss to a Michigan over distance of 50.0m. Find the opposition force, presuming it ââ¬Ës changeless.Solution( a ) Find the acceleration of the airboat. Apply Newton ââ¬Ës 2nd jurisprudence and work out for the acceleration: Fnet = mom a = = = 2.20m/s2 ( B ) Find the clip necessary to make a velocity of 12.0m/s. Use the kinematics velocity equation: If t = 5.45s V = at + V0 = ( 2.20m/s2 ) ( 5.45 ) = 12.0m/s ( degree Celsius ) Find the opposition force after the engine is turned off. Using kinematics, find the net acceleration due to resistance forces V2 ââ¬â = 2a Iâ⬠x 0 ââ¬â ( 12.0m/s ) 2 = 2a ( 50.0m ) = -12 / 100 = -0.12m/s2 Substitute the acceleration into Newton ââ¬Ës 2nd jurisprudence, happening the opposition force: Fresistance= mom = ( 3.50 X 102kg ) ( -144m/s2 ) = -504NImpulse and Impulsive ForceThe force, which acts during a short minute during a hit, is called Impulsive Force. Impulse is defined as the alteration of impulse, so Impulse = MV ââ¬â Mu, since F = , therefore impulse can be written as: Impulsive force is Force = Impulse/Time. Unit is Newton ( N ) .The applications of unprompted forceIn existent life we tend to diminish the consequence of the unprompted force by cut downing the clip taken during hit.Gravitational force or gravitationGravity exists due to the Earth ââ¬Ës mass and it is Acts of the Apostless towards the centre of Earth. Object falling under the influence of gravitation will see free autumn. Assuming no other force acts upon it. Object sing free autumn will fall with acceleration ; gravitation has an approximative value of 10m/s2. The gravitative force moving on any object on Earth can be expressed as F=mg. This is besides every bit weight.For illustrationFind the gravitative force exerted by the Sun on a 79.0kg adult male located on Earth. The distance from the Sun to the Earth is about 1.50 Ten 1011 m, and the Sun ââ¬Ës mass is 1.99 Ten 1030kg.SolutionFsun = G = ( 6.67 X 10-11 Kg-1m3s2 ) = 0.413NNewton ââ¬Ës 3rd jurisprudenceThe action of one organic structure moving upon another organic structure tends to alter the gesture of the organic structure acted upon. This action is called a force. Because a force has both magnitude and way, it is a vector measure, and the old treatment on vector notation applies. Newton ââ¬Ës 3rd jurisprudence is the sum of force which you inflict upon on others will hold the same repelling force that act on you every bit good. Force is exerted on an object when it comes into contact with some other object. See the undertaking of driving a nail into a block of wood, for illustration, as illustrated in the figure 1.7 ( a ) . To speed up the nail and drive it into the block, the cock must exercise a net force on the nail. Newton is a individual stray force ( such as the force exerted by the cock on the nail ) could n't be. Alternatively, forces in nature ever exist in braces. Harmonizing to Newton, as the nail is driven into the block by the force exerted by the cock, the cock is slowed down and stopped by the force exerted by the nail. Newton described such mated forces with his 3rd jurisprudence: Whenever one object exerts a force on a 2nd object, the 2nd exerts an equal and opposite force on the first. This jurisprudence, which is illustrated in figure 1.7 ( B ) , province that a individual stray force ca n't be. The force F12 exerted by object 1 on object 2 is sometimes called the action force, and the force F12 exerted by object 2 on object 1 is called the reaction force. In world, either, either force can be labeled the action or reaction force. The action force is equal in magnitude to the reaction force and antonym in way. In all instances, the action and reaction forces act on different objects. For illustration, the force moving on a freely falling missile is the force exerted by Earth on the missile, Fg, and the magnitude of this force is its weight milligram. The reaction to coerce Fg is the force exerted by the missile on Earth, Fg = -Fg. The reaction force Fg must speed up the Earth towards the missile, merely as the action force Fg accelerates the missile towards the Earth. Because the Earth has such a big mass and its acceleration due to this reaction forces is negligibly little. Figure 1.7: Newton ââ¬Ës 3rd jurisprudence. ( a ) The force exerted by the cock on the nail is equal in magnitude and antonym in way to the force exerted by the nail on the cock. ( B ) The force F12 exerted by object 1 on object 2 is equal in magnitude and antonym in way to the force F21 exerted by object 2 on object 1. Newton ââ¬Ës 3rd jurisprudence invariably affects our activities in mundane life. Without it, no motive power of any sort would be possible, whether on pes, on a bike, or in a motorised vehicle. When walking, we exert a frictional force against the land. The reaction force of the land against our pes propels us frontward. In the same manner, the tired on a bike exert a frictional force against the land, and the reaction of the land pushes the bike frontward. This is called clash plays a big function in such reaction forces. Figure 1.8: In the figure 1.8, when a force pushes on an object, the object pushes back in the opposite way. The force of the forcing back is called the reaction force. This jurisprudence explains why we can travel a dinghy in H2O. The H2O pushes back on the oar every bit much as the oar pushes on the H2O, which moves the boat. The jurisprudence besides explains why the pull of gravitation does n't do a chair clang through the floor ; the floor pushes back plenty to countervail gravitation. When you hit a baseball, the chiropteran pushes on the ball, but the ball besides on the chiropteran. Figure 1.9Question TwoResearch and exemplify the assorted features of ââ¬Å" Damped Oscillations â⬠, your reply should besides include graphical show of these characteristic.AnswerIn the existent life, the vibrating gesture can be taken topographic point in ideal systems that are hovering indefinitely under the action of a additive restoring force. In many realistic system, resistive forces, such as clash, are present and retard the gesture of the system. Consequently, the mechanical energy of the system diminishes in clip, and the gesture is described as a damped oscillation. Therefore, in all existent mechanical systems, forces of clash retard the gesture, so the systems do n't hover indefinitely. The clash reduces the mechanical energy of the system as clip base on ballss, and the gesture is said to be damped. In the figure 2.0, daze absorbers in cars are one practical application of damped gesture. A daze absorber consists of a Piston traveling through a liquid such as oil. The upper portion of the daze absorber is steadfastly attached to the organic structure of the auto. When the auto travels over a bump in the route, holes in the Piston let it to travel up and down in the fluid in a damped manner. ( B ) Figure 2.0: ( a ) Angstrom daze absorber consists of a Piston hovering in a chamber filled with oil. As the Piston oscillates, the oil is squeezed through holes between the Piston and the chamber, doing a damping of the Piston ââ¬Ës oscillations. ( B ) One type of automotive suspension system, in which a daze absorber is placed inside a spiral spring at each wheel. Damped gesture varies with the fluid used. For illustration, if the fluid has a comparatively low viscousness, the vibrating gesture is preserved but the amplitude of quiver lessenings in clip and the gesture finally ceases. This procedure is known as under damped oscillation. The place vs. clip curve for an object undergoing such as oscillation appears in active figure 2.1. In the figure 2.2 compares three types of damped gesture, with curve ( a ) stand foring underdamped oscillation. If the fluid viscousness is increased, the object return quickly to equilibrium after it is released and does n't hover. In this instance the system is said to be critically damped, and is shown as curve ( B ) in the figure 2.2. The Piston return to the equilibrium place in the shortest clip possible without one time overshooting the equilibrium place. If the viscousness is greater still, the system is said to be overdamped. In this instance the Piston returns to equilibrium without of all time go thro ughing through the equilibrium point, but the clip required to make equilibrium is greater than in critical damping. As illustrated by curve ( degree Celsius ) in figure 2.2. Active figure 2.1: A graph of displacement versus clip for an under damped oscillator. Note the lessening in amplitude with clip. Figure 2.2: Plots of displacement versus clip for ( a ) an under damped oscillator, ( B ) a critically damped oscillator, and ( degree Celsius ) an overdamped oscillator. Damped oscillation is relative to the speed of the object and Acts of the Apostless in the way opposite that of the object ââ¬Ës speed relation to the medium. This type of force is frequently observed when an object is hovering easy in air, for case, because the resistive force can be expressed as R = -bv, where B is a changeless related to the strength of the resistive force, and the reconstructing force exerted on the system is -kx, Newton ââ¬Ës 2nd jurisprudence gives us = -kx ââ¬â bv = soap -kx ââ¬â B = m ~ ( I ) The solution of this differential equation requires mathematics that may non yet be familiar to you, so it will merely be started without cogent evidence. When the parametric quantities of the system are such that B & lt ; so that the resistive force is little, the solution to equation is Ten = ( Ae- ( b/2m ) T ) cos ( wt + ) ~ ( two ) Where the angular frequence of the gesture is = ~ ( three ) The object suspended from the spring experience both a force from the spring and a resistive force from the environing liquid. Active figure 2.1 shows the place as a map of clip for such a damped oscillator. We see that when the resistive force is comparatively little, the oscillating character of the gesture is preserved but the amplitude of quiver lessenings in clip and the gesture finally creases, this system is known as an underdamped oscillator. The dotted blue lines in active figure 2.1, which form the envelope of the oscillatory curve, represent the exponential factor that appears in equation ( two ) . The exponential factor shows that the amplitude decays exponentially with clip. It is convenient to show the angular frequence of quiver of a damped system ( three ) in the signifier=Where = a?sk/m represents the angular frequence of oscillation in the absence of a resistive force ( the undamped oscillator ) . In other words, when b=o, the resistive force is zero and the system oscillates with angular frequence, called the natural frequence. As the magnitude of the resistive force additions, the oscillations dampen more quickly. When B reaches a critical value bc, so that bc/2m = , the system does non hover and is said to be critically damped. In this instance, it returns to equilibrium in an exponential mode with clip, as in figure 2.2. Question Three: Simple Harmonic Motion ( SHM ) is a dynamical system typified by the gesture of a mass on a spring when it is capable to the additive elastic reconstructing force given by Hooke ââ¬Ës Law. The gesture is sinusoidal in clip and demonstrates a individual resonant frequence. What is the relationship between the tenseness and weight in the system? What is Hooke ââ¬Ës jurisprudence when applied to the system?AnswerOscillation of gesture is has one set of equations can be used to depict and foretell the motion of any object whose gesture is simple harmonic. The gesture of a vibrating object is simple harmonic if its acceleration is relative to its supplanting and its acceleration and supplanting are in opposite way. The 2nd slug point mean that are acceleration, and hence the end point force, ever acts towards the equilibrium place, where the supplanting is zero. Common illustrations of simple harmonic gesture include the oscillations of a simple pendulum and those of a mass suspended vertically on a spring. The diagram shows the size of the acceleration of a simple pendulum and a mass on a spring when they are given a little supplanting, x, from the equilibrium place. Figure 3.0 In the figure 3.0, the numerical value of the acceleration is equal to a changeless multiplied by the supplanting, demoing that acceleration is relative to displacement. Then, the negative value of the acceleration shows that it is in the opposite way to the supplanting, since acceleration and supplanting are both vector measures.Simple harmonic in a springIf you hang a mass from a spring, the mass will stretch the spring a certain sum and so come to rest. It is established when the pull of the spring upward on the mass is equal to the pull of the force of gravitation downward on the mass. The system, spring and mass, is said to be in equilibrium when that status is met. If the mass is up or down from the equilibrium place and release it, the spring will undergo simple harmonic gesture caused by a force moving to reconstruct the vibrating mass back to the equilibrium place. That force is called the restoring force and it is straight relative to magnitude of the supplanting and is directed opposite the supplanting. The necessary status for simple harmonic gesture is that a reconstructing force exists that meets the conditions stated symbolically as Fr = -kx, where K is the invariable of proportionality and ten is the supplanting from the equilibrium place. The subtraction mark, as usual, indicates that Fr has a way opposite that of ten.For illustrationFigure 3.1 The grouch rotates with angular speed w. Then, the slide will skid between P1 and P. V2 = W2 ( P2-X2 ) P = Amplitude or maximal point. V= Velocity of the skidder. Ten = Distance from centre point due to speed, V. W = Angular speed of grouch. = 2IÃâ f degree Fahrenheit = = 1/T a = -w2xSimple pendulumA simple pendulum is merely a heavy atom suspended from one terminal of an nonextensile, weightless twine whose other terminal in fixed in a stiff support, this point being referred to as the point of suspension of the pendulum. Obviously, it is merely impossible to obtain such an idealised simple pendulum. In existent pattern, we take a little and heavy spherical British shilling tied to a long and all right silk yarn, the other terminal of which passes through a split cork firmly clamped in a suited base, the length ( aââ¬Å¾Ã¢â¬Å" ) of the pendulum being measured from the point of suspension to the Centre of mass of the British shilling. In the figure 3.2, allow S be the point of suspension of the pendulum and 0, the mean or equilibrium place of the British shilling. On taking the British shilling a small to one side and so gently let go ofing it, the pendulum starts hovering about its average place, as indicated by the flecked lines. At any given blink of an eye, allow the supplanting of the pendulum from its average place SO into the place SA is I? . Then, the weight milligram of the British shilling, moving vertically downwards, exerts a torsion or minute ââ¬â mg/sin I? about the point of suspension, be givening to convey it back to its average place, the negative mark of the torsion bespeaking that it is oppositely straight to the supplanting ( I? ) . Figure 3.2 If d2I?/dt2 be the acceleration of the British shilling, towards 0, and I its M.I about the point of suspension ( S ) , the minute of the force or the torsion moving on the bobn is besides equal to I.d2I?/dt2. I = -mgaââ¬Å¾Ã¢â¬Å"sinI? If I? is little, the amplitude of oscillation be little, we may pretermit all other footings except the first and take wickedness I? = I? . I = -mgaââ¬Å¾Ã¢â¬Å"I? , Whence, = Since M.I of the British shilling about the point of suspension ( S ) is maââ¬Å¾Ã¢â¬Å"2. We have = = = Aà µI? , Where = Aà µ The acceleration of the British shilling is therefore relative to its angular supplanting I? and is directed towards its average place 0. The pendulum therefore executes a simple harmonic gesture and its clip period is given by T = 2IÃâ = 2IÃâ = 2IÃâ It being clearly understood that the amplitude of the pendulum is little. The supplanting here being angular, alternatively of additive, it is evidently an illustration of an angular simple harmonic gesture.Hooke ââ¬Ës jurisprudenceVibration gesture is an object attached to a spring. We assume the object moves on a frictionless horizontal surface. If the spring is stretched or compressed a little distance ten from its equilibrium place and so released, it exerts a force on the object as shown in figure 3.3. From experiment the spring force is found to obey the equation F = -kx ~ ( four ) Where ten is the supplanting of the object from its equilibrium place ( x=0 ) and K is a positive invariable called the spring invariable. This force jurisprudence for springs is known as Hooke ââ¬Ës jurisprudence. The value of K is a step of the stiffness of the spring. Stiff springs have big K value, and soft springs have little K value. In the equation ( four ) , the negative mark mean that the force exerted by the spring is ever directed opposite the supplanting of the object. When the object is to the right of the equilibrium place, as in figure 3.3 ( a ) , x is positive and F is negative. This means that force is the negative way, to the left. When the object is to the left of equilibrium place, as in figure 3.3 ( degree Celsius ) , x is negative and F is positive, bespeaking that the way the force is to the right. Of class, when ten = 0, as in figure 3.3 ( B ) , the spring is unstretched and F =0. Because the spring force ever acts toward the equilibrium place, it is some clip called a restoring force. A reconstructing force ever pushes or pulls the object toward the equilibrium place. The procedure is so repeated, and the object continues to hover back and Forth over the same way. This type of gesture is called simple harmonic gesture. Simple harmonic gesture occurs when the net force along the way of gesture obeys Hooke ââ¬Ës jurisprudence ââ¬â When the net force is relative to the supplanting from the equilibrium point and is ever directed toward the equilibrium point. Figure 3.3: The force exerted by a spring on an object varies with the supplanting of the object from the equilibrium place, x=0. ( a ) When ten is positive ( the spring is stretched ) . ( B ) When ten is zero ( the spring is unstretched ) , the spring force is zero, ( degree Celsius ) When ten is negative ( the spring is compressed ) , the spring force is to the right.DecisionAs my decision, Newton ââ¬Ës jurisprudence was a really utile in presents because it is can utilize the 3 type of jurisprudence to forestall any accidents in now coevals. First ââ¬Ës jurisprudence is provinces that a force must be applied to an object in order to alter its speed. Second ââ¬Ës jurisprudence is acceration of an object is straight relative to the net force moving on it and is reciprocally relative to its mass. Third ââ¬Ës jurisprudence is whenever we push on something, it pushes back with equal force in the opposite way. Second, harmonic oscillation is a type of forced and damped oscillation that is amplitude of a existent vacillation pendulum or hovering spring lessening easy with clip until the oscillation stop wholly. This decay of amplitude as a map of clip is called damping.

Managing Bullying and Harassment in the Workplace
Workplace Bullying (the persistent exposure to interpersonal aggression and mistreatment from colleagues, superiors or subordinates) is a reverent problem in contemporary working life, with devastating effects on both targets and organizations (Nearest, Hole, Zap, & Cooper 2003; Earner & Seashell, 2005) There are different forms of bullying in this 21 SST century as it need not be physical with such advancement in technology. Bullying can be direct, indirect passive and through social media as well. Therefore we must outline the scope on what is bullying and what is not before we are able to draw up a way to manage such incidents.There is no specific legislation to combat workplace bullying in Singapore (Jay Parka's, Inciting Injury: An Expos of workplace bullying in Singapore). There are many a time where workplace bullying is so minute in nature and often left undulate with that it is left unnoticed, however this acts of bullying builds up in time creating a hostile and fragile wor king environment. What is bullying and harassment? Physical and verbal abuse can be factored in as bullying but other forms of bullying may be too subtle. Harassment can be a highly sensitive topic as each individual person can take it to be in different ways.What one individual considers being an act of playful gesture the involved party may think otherwise. The Workplace Bullying Institute defines workplace bullying as ââ¬Å"abusive conduct that is; threatening, humiliating, intimidating, or work interference and verbal abuseâ⬠. The consequences to the employers may include; reduced efficiency, productivity and profitability. Increase in absenteeism, sick leaves and staff turnover. Increase in indirect costs such as management time, engaging mediators and counselors. This list is not exhaustive as there are many other uniqueness an employer might face due to workplace bullying.On the other hand when we are to look at the consequences for the employees workplace bullying and harassment can cause extensive health problems including physical and psychological illnesses and injuries causing detrimental effects for them. Therefore for the organization to work towards sustainability it is important to first identify and try to eradicate if not hundred percent at least 90 percent of this problem, reason being it is not only the victim who suffers and feels the effects of bullying it is felt across all bevels of the organizations as we have seen from the non-exhaustive list given above.While it may seem that the above analysis may provide an insight into bullying in organizations, it is becoming evident that management has to start taking proactive steps and measures in identifying and putting forth solutions and implementations to address these pressing needs whereas if not losses can be incurred for the organization. 00006718 The first step to this is that the organization spells out clearly their stance and their outline on bullying and harassment before a person is being pointed to any post in the organization, also the management of the organization should clearly state and constitute which activities are considered to be bullying or harassment therefore making it difficult for employees to find any loopholes in the system therefore escaping the penalties.Once this is done, a directive should be spelled out and sent out to all employees in the organization regardless of their position or role in the organization, therefore bringing everyone in the organization to a common single understanding. Clear penalties and actions should also be included in he directive so as to deter any potential bullies from committing such acts. All staff across the board should be made to sign this directive enabling the management to take actions and hold guilty employees liable .These directives should be clearly formalized and well communicated to the frontline managers so that they can take actions if any one of the staff were to breach the directive . Secondly the organization should have a clear communication channel across the board from bottom up. Staff and personal across all level should have access to this communication channel and mad ware of such communication channel. The magnitude of effective internal communication is evident in past researches ( Muhammad Raff et al. 2009; Mark Chon, 2007) For example, Barrett (2002) accentuates, the best way to reach and employee is via face to face communication than relying on indirect channels such as electronic media. Falkland and Hide (2008) emphasizes on bottom-up communication. Furthermore, Welch and Jackson (2007) claims that, rather than treating employees as a single public, they should be segmented based on say structural levels of demographics. This can help in insuring that the relevant information targeted to reach the relevant person can reach them in a meaningful and smooth manner.Therefore with such communication channels put in place the management team are well aw are of complaints against bullying in any levels of the organization and necessary steps and actions can be taken swiftly. Special helpline or trained HER staff in the area of counseling can be put in place to tackle sensitive issues which some employees may find it difficult in putting forth to their direct supervisors. Information from all cases must be upheld with the highest infallibility so as to protect the interests of the employee who is suffering or facing bullying or harassment in the organization.Lastly is to create a strong bond among the employees working in the organization. Inculcating a strong sense of bond between them and creating a strong sense of ownership towards the company and its common goal would enable the employees to work hand in hand to achieve the goals thus enabling the organization to realize its true benefits and bring out the fullest from an employee. If strong bonds are created at the start employees would e able to identify the differences which t hey have and sort them out accordingly without the help of the management of the interference of their superiors thus creating a better working environment.To achieve this, the organization can hold yearly bonding activities for their employees, invite professionals to give their opinions and facts on employee relationships, hold monthly meetings to iron out any issues arising and to let the employees swiftly handle the matter within themselves, Muhammad Shaffer s/o Mohamed Kids In conclusion, a well working and robust organization largely depends on heir sustainability of their employees. Toxic and unfriendly working environment may lead the organization to lack in certain areas, therefore immobility's the organization in their growth.Organizations should therefore from the Start deter such bullying and harassment issues, even if these issues were to crop up in the later part of the organizations growth the management must be swift in handling and weeding out such problematic activ ities before it impacts the whole organization. As said above, bullying or harassment does not only affect the person who is the victim it's effects can be felt across the hole organization as a whole.

Graphing - Speech or Presentation Example Original equation is equal to y=3/2 x+ c and the gradient is 3/2. The product of gradient of perpendicular and original line is -1. Therefore, 3/2 (m2) =-1. M2 becomes -2/3. The equation of perpendicular is therefore y=-2/3 x+ c. One line is parallel to another if the lines can never meet when extended in both directions. Parallel lines have the same gradient or slope hence they never meet each other. Parallel lines are easily determined by comparing gradients or slopes of each given lines in their equations. The equations are normally in the form of y=mx+c, whereby y represents the values of y-axis in the line and x represents the values of x-axis. M represents the gradient or the slope of the line while c represents the y-intercept. Y-intercept is a point where the line cuts the y-axis. X-intercept is a point where the line cuts the x-axis. Lines are said to be perpendicular to each other if the product of their gradients is equal to -1. This means that perpendicular lines meet at a right angle, that is, the angle between perpendicular lines is 90Ã °. The ordered pair or the coordinate of their meeting point is equal. Given the equation of a line, one can determine the gradient of the perpendicular line by finding the negative reciprocal of the gradient of the original line. Coordinate (0, 0) is referred to as the origin. It is the meeting point of y-axis and x-axis. Coordinates or ordered pair must be enclosed in a

Realism and the Lord of the Ring 3 Movie Essay Example | Topics and Well Written Essays - 1250 words
Realism and the Lord of the Ring 3 Movie - Essay Example Yet again, the absence of a regulating body makes the agents relate with one another on their own without being directed by a higher authority according to Crawford (45). It is also noted that since the players in the realism pitch do so in an environment that is unstable as they scramble for the same resources. As a result, sometimes the players engage in war in which case they have themselves to depend on. Before nationalism came into being as a political doctrine, realism in the political scene involved such jurisdictions as ruling dynasties and kingdoms (Mearsheimer 87). Generally, the realist ideology demands that the relevant agent ensures its own interests and survival before it can extend a glance to othersââ¬â¢ needs. Connection between Realism and The Lord of the Rings: The Return of the King (2003) The epic fantasy film The Lord of the Rings: The Return of the King which is based on the preceding volumes of the The Lord of the Rings trilogy. In brief, Sauron has been se eking to launch his conquest of Middle-earth. On the other hand, Theoden King of Rohan and Wizard Gandalf join forces to defend Minas Tirith (the capital of Gondor) from the impending danger. In the end, Aragorn claims Gondorââ¬â¢s throne and seeks the help of an army of ghosts to battle against Sauron. Even with the massive and remarkable force behind them, they realize that their lot is bound to be defeat. Sam, Frodo and the Hobbits have to shoulder the Ringââ¬â¢s burden and deal with Gollumââ¬â¢s treachery. A long journey sees them arrive in Mordor, a land that is quite full of danger. They desire to destroy the One Ring where it was created ââ¬â using Mount Doomââ¬â¢s volcanic fires. The Lord of the Ring: The Return of the... Realism has continued to gain ground especially following the events of the Second World War. Realism, according to political scientists may be defined as the belief that reality essentially exists without respect to observers. Politically, realism is seen at play in international relations whenever national or territorial interests and security are given higher priority over social reconstructions, ideology and moral concerns. Ideally, the growing interest in realism comes about with the view that competitive self interest is the main driver of world politics. The application of realism or realist notions and perspectives is prevalent across the world. The main characteristics of realism include the desire for agents to secure themselves against threats and to protect their interests first before considering those of other players or agents. In the movie The Lord of the Rings: The Return of the King, realism is beyond doubt in existence. The various battles that are fought in the movie are aimed at protecting the interests of particular jurisdictions or individuals. Yet again the security of the jurisdictions is considered whenever threats seem to emerge from external forces. The absence of a governing body makes the playing field open to conflict as the fight for resources becomes evident. In spite of the above facts, it cannot be ignored that some players overcome the temptations associated with seeking power in a move that downplays the ideals of realism. The Lord of the Ring: The Return of the King is an epic-fantasy movie that starts off with the evil Sauron launching the final phases of his take-over of Middle-earth while Gandalf and Theoden assist in defending Minas Tirith.

Oil in Venezuela Research Paper Example | Topics and Well Written Essays - 2750 words
Oil in Venezuela - Research Paper Example Despite the knowledge of oil for ages the, the first oil wells were not drilled up until 1910s. According to McBeth (2005) asserts that when Juan .V. Gomez took the reigns of power in 1908, he granted several concessions to explore, produce and refine oil. Most of these concessions were actually given to his closest allies, and they in turn passed them over to foreign oil companies that could develop them. From 1914 to 1917, more oil fields were discovered across the nation. By the end of 1918, petroleum had appeared for the very first time in Venezuelan exportââ¬â¢s statistics at 21,194 metric tonnes (Martinez, 1979). After 20 years, Venezuela became the largest oil exporter in the whole world and second largest oil producer after the United States of America. This led to an influx of foreign investors. By 1929, with the nation being the second largest oil producer in the world. Currently, Venezuela is the fifth largest oil exporting nation in the world, with the largest reserves of both conventional oil in the western hemisphere and non-conventional oil. This fact is very immense importance to the understanding of Venezuela because it has shaped the countryââ¬â¢s political, economical, cultural, and historical scenes (Wilpart, 2003). Venezuela has 77.2 billion barrels of proven conventional oil reserves, the largest in any state in the Western Hemisphere. Approximately 267 barr els of this might be producible at current prices utilising the current technology. Venezuela was the first country to make a move towards the establishment of the Oil Producing and Exporting Countries (OPEC). It approached Saudi Arabia, Kuwait, Iran, Gabon, and Libya in 1949, but OPEC was not set up until 1960. This was when the United States forced import quotas on the Persian and Venezuelan Gulf oil so as to support the Canadian and Mexican oil industries (Martinez, 1979). In 1973, OPEC wielded its first power with the 1973 oil embargo against Western Europe and the United States. Discussion Economy In Venezuela, there was dramatic development of the oil industry, and the oil sector commenced to dominate all other economic sectors in the country. On the other hand, agricultural production began to decline slowly. Agriculture accounted for about one third of the economic production in 1920. According to Yergin (1999) argues that this sudden change increases attention on oil and ne glecting the agricultural sector causing the Venezuelan economy to suffer from a phenomenon referred by economists as the ââ¬Å"Dutch diseaseâ⬠. The occurrence of this disease is manifested when a commodity brings substantial increase in income in one sector, resulting in strengthening of the currency which in turn harms exports of the other manufacturing sectors. This increased sectoral income has caused a distorted growth in services and other non-tradables, which can not be imported whilst discouraging the production of tradables, which are actually imported. The reason for this disparity is that, greater income dramatically raises the demand for imports because the domestic market production can not meet the production quickly enough. This raises the demand for services of which the domestic market has to supply because the services can not be easily imported as the tradables. When one looks at the extent to which there has been increased oil production and income, which w as followed by a corresponding steady decrease in agricultural production, one can clearly observe the symptoms of Dutch disease in the Venezuelan economy. This resulted in a delay in industrialization. The other Dutch disease symptoms are evident in the constant

The Skeletal System Essay Example | Topics and Well Written Essays - 250 words
The Skeletal System - Essay Example Finally, bones contain bone marrow from the red blood cells develop and are also storing housed for important minerals like calcium and phosphorus. In terms of anatomy, the skeleton is divided into two parts: the axial skeleton which contains all the bones in our body and the appendicular skeleton which is associated with our limbs and performs the function of movement. Bones are not the only important part of the skeletal system; the other important feature is the joints. Joints connect two bones and allow the body to rotate or flex around those joints. There are three different types of joints: synarthosis joints, amphiarthrosis joints, and diarthrosis joints. These classifications have been made according to the freedom of movement these joints allow. Synarthosis joints are immovable, amphiarthosis joints are slightly moveable whereas diarthosis thosis joints are freely movable and can allow bending, straightening and various other functions. Many of the deficiencies as well as the other causes leading to physical problems lie at the heart of these joints where the movement around these joints is either stopped or enhanced. Therefore in order to make medical advances regarding such condition, it is very important to study different types of

Criminal Justice System Essay Example | Topics and Well Written Essays - 1000 words - 3
Criminal Justice System - Essay Example I can describe criminal justice, generally as a collapse and disappointment from what we expect of it. In areas of a majority of white ethnic groups, their black ethnic counterparts are faced with high levels of discrimination as far as criminal justice is concerned; which leaves them helpless and fearful. Individuals from black ethnic groups are often regarded suspects in crimes they havenââ¬â¢t committed. With the increase in civil rights protection, there has been hardly any feel of it among the black ethnic group. For instance, an individual from the black ethnic group is most likely to face a prison sentence as compared to one from the white ethnic group; when both are found guilty of using illegal drugs. There also are cases of lower police protection in black ethnic group neighborhoods as compared to their counterparts; which, therefore, is a clear indication of how much the criminal justice has failed. Despite the mentioned mistreatment of the black ethnic groups by some p olice, there are a number of policemen who make this career feel satisfying and worth pursuing. Being put in charge of peopleââ¬â¢s lives to offer protection and serve the nation is something to take pride in. Some special agents and others in the field of criminal justice are also responsible for the rehabilitation, protection of wildlife, the environment; which is a good feeling as they know that they are helping others.

Critical Annotated Bibliography Tranexamic Acid Essay
Critical Annotated Bibliography Tranexamic Acid - Essay Example Amandip Singh is also a doctor in the department of anaesthesiology at DMCH. The researchers assert that tranexamic acid significantly decreases blood loss after operation and reduces the need for blood transfusion among students after undergoing total knee replacement (TKR).According to the researchers, Tranexamic acid, which is a synthetic derivative of amino acid lysine, is an effective antifibrinolytic agent. The acid is may reversibly block lysine-binding sites on the plasminogen molecules, thus hinder the formation of plasmin. Other researchers have showed increased use of tranexamic acid in orthopaedic surgery due to its safety, efficacy and low cost. The research was conducted in a tertiary health care facility after obtaining approval from the hospital heath ethics committee with informal consent taken from patients involved in the study. The researchers used randomized double-blinded study involving 40 patients scheduled to undergo unilateral TKR for osteoarthritis. Three s urgeons who had experience in the field to ensure validity of the test conducted the study. The first half of the population was injected with 10mg/kg of tranexamic acid. Conversely, the placebo group underwent the same procedure only that normal saline was used instead of tranexamic acid. ... It was concluded that routine administration of the acid was beneficial to patients undergoing operation. The limitation of the research is that it involved a limited number of populations. Also, the researchers did not monitor the plasminogen levels, D-dimer, thromboelastography, and fibrin degradation products. In addition, the researchers failed to measure hemoglobin levels of transfused blood and weigh sponges, which could have affected the accuracy of calculations. The text did not have sufficient clinical evidence and literature supporting the use of tranexamic acid in preventing preoperative blood loss. The relevance and usefulness of the text to my research is that it informed on the importance of the Tranexamic acid in reducing blood loss during operations in patients. Sekhavat, L., Tabatabaii, A., Dalili, M., Farajkhoda, T., & Tafti, A. (2009). Efficacy of tranexamic acid in reducing blood loss after cesarean section. The Journal Of Maternal-Fetal & Neonatal Medicine. Vol. 22(1), 72-75. The authors of this research journal are medical practitioners at the department of obstetrics and gynecology at Shahod Sehud Hospita, and Health Services, Yard, Iran. They have the ability to produce credible research that can be used in any academic research. The argument presented by the researchers is that cesarean section (CS) rate has been on the increase among women delivering and that CS posse many complications as compared to the normal vaginal birth due to complications related to postpartum bleeding. The medications that have been used to reduce bleeding include prostaglandins, oxytocin, and methylergonovine. The researchers however feel that tranexamic acid, a synthetic derivative of the amino acid lysine that has been applied for several years in the

Silver and gold Research Paper Example | Topics and Well Written Essays - 2500 words
Silver and gold - Research Paper Example This paper seeks to analyze the historical background of silver and gold, their ancient and modern uses, the manufacturing process, the impact the materials have on the environment, their cultural significance, and future innovations on the usage of the metals. Silver History of Silver The first major silver mines were discovered in Anatolia, which is the modern day Turkey, in 3000 BC. In the 1st Century AD, Spain became a key silver producer due to Roman discoveries. In early 1500s huge silver deposits were found in Bolivia, Peru, and Mexico which enriched the Spanish empire for a period of 300 years. In the period 1500 to 1875 about 1.5 billion ounces of silver were mined in Mexico with a large percentage mined in the 1700s. In the 1700s, silver became the backbone of Spanish Empire and 1 billion ounces was mined in the Veta Madre in Mexico. 1857 saw the state of Nevada adopting Silver mining as a major industry when Comstock Lode was found in Nevada. Nevada became to be known as t he silver state because of the silver mining. From 1857 to 1877, Comstock produced gold and silver of an approximate value of 400 million US dollars which could have been worth about 500 Billion US dollars in the modern days. There was a 50 percent increase in the global yield of Silver between 1900 and 1920. This amounted to about 190 million troy ounces per year and discoveries were made in other countries such as the United States and Canada. From 1921 to present improved techniques has led to separation of Silver from Zinc, copper and lead. This has led to an increase in production of Silver and its usage. Silver was among the first metals known to man. The other metal is gold. The ancient population valued Silver because of its white color, brilliant luster, non-corrodibility nature and it was relatively easy to work with. Today, silver still stands out as one of the most valued metals because of the above properties but several other characteristics have changed the trend of s ilver usage from being merely monetary and decorative metal to being predominantly an industrial metal. Usage of Silver Silver is a soft, malleable and the most ductile among the metals. These properties have led to it being fabricated into personal adornment items and decorative items of various types. Hence, chain necklaces, neck rings, silver bracelets, and other jewelry items were developed as from ancient times. In the later days, silver was used to make decorative things such as handles for swords and daggers and later when approaching the modern times it was fashioned into eating utensils and various tableware items. The industrial usage of silver arose in the 19th and 20th centuries. The following section illustrates the chronological account for the usage of silver. In the 1820s, silver and silver salts became major component for the development of photography. Since the late 1830s, silver has been used in the manufacture of silver-mercury amalgams that are used for restori ng teeth. In the third millennium BC the Egyptians made mirrors of polished silver while ââ¬Å"silveringâ⬠of mirrors with metals such as mercury, tin and lead was adopted in Europe before Renaissance period. In 1835, Justus von Liebig invented the process of large scale production of silvered glass through a chemical reduction of silver nitrate compound. In 1840, the process for electroplating of silver was granted a patent and it was the first patent to be granted for electroplating any metal. Alessandro Volta used silver and zinc for making
What is a Barrier Island Essay Example | Topics and Well Written Essays - 2500 words
What is a Barrier Island - Essay Example Barrier island is normally a thin and elongated area of land that is largely made up of sand. Habitat: Barrier islands are located on the North America east coast in such places as North Carolina, New Jersey, and Florida. Some barrier islands are also situated along the gulf coast, i.e. Louisiana. Different components of a typical barrier island include but are not limited to dunes, salt marshes, oceans, mainlands, back dunes, and bays. A dune is a hilly area made up of sand brought with the passage of wind. Back due, as the name implies, forms that rear part of a dune. When salt water overflows somewhere, flat pieces of land emerge that are known as salt marshes. Small bodies of water that are distant from the main water body with a large volume are known as bays. All of these places provide different types of organisms with habitat. Organisms like spiders, egg-laying animals usually occupy the regions in the vicinity of the dunes or oceans. Some of the most common animals that live on the beaches of the barrier islands are seagulls, burrowing worms, pelicans and scavenging crabs. Different kinds of terns and crabs live in the dunes. The number of organisms living in a barrier island depends upon its size. In large barrier islands, there are more habitats to accommodate more organisms. Likewise, smaller islands offer fewer habitats for lesser animals. Weather conditions in the barrier islands: Barrier islands have harsh conditions. There are frequent speedy wind blows and sand blows that result into extreme dryness. The coastal storms are so powerful and full of energy that they can totally ruin the barrier islands. They are empowered by such features of the natural environment on the barrier islands as high tides and waves. The constant change in the weather conditions causes an equivalent change in the habitat. The animals that live there have adapted themselves to survive in extreme conditions accordingly. Likewise, the human population that lives on the ba rrier islands is also equipped with the required necessities to combat the extremity of weather. Most people who live in the barrier islands at a certain point in time do not occupy them permanently. People construct homes on them to use them temporarily as they spend their time on the barrier islands during summer vacations. Effects of storms on the barrier islands: Along with affecting the animals and humans, the coastal storms also have a severe impact on the form and shape of the barrier islands. A lot of erosion occurs on the dunes when coastal storms occur. Severe forms of coastal storms can fully damage the dune system. The power of the coastal storms can be estimated from the fact that just one storm can disintegrate all components of a barrier island and completely wash it away. Barrier islands may disappear as a result, though it only takes one to two years for a lost barrier island to resurface. Originally, the deterioration of an island is not physically noticeable. But the currents of wave increase in their size and energy level when the island is actually gone. Summary of the concept: A barrier island is a region that is largely made up of sand and its function is to serve as a barrier between the coastal storms and the mainland.Ã

Consumer Sciences Education Essay Puberty is the period when children experience various physical and emotional changes in their bodies. Puberty comes with psychological effects that affect the teenââ¬â¢s interaction at school, with their peers and parents. Puberty Puberty is the stage in childrens lives when they experience physical changes through which their bodies eventually develop into adult bodies that are capable of reproducing. It is triggered by hormonal signals that stimulate the growth, function and change in different parts of the body, including the reproductive organs, breasts, skin, muscles, bones, hair and the brain depending on the sex (Allison, 2000). Puberty has various psychological effects within the school context, peers and parents. Within the school context puberty has wide psychological effects like searching identity and role confusion. It impacts their choice of career, sports activities, work schedule and tend to rebellious to the administration. It has been noted that adolescents prefer more liberal schools. At the same time the transition for example to high school has various effects on their academic achievement (Steinberg, 2001). During puberty, adolescents have very high regard for their peers. They measure who they are, their morals and lifestyles against them. Young people struggle to belong and to be accepted and affirmed by their peers, and yet also to become individuals. This desperate need for acceptance may explain why many teens engage in substance abuse and sexual activities. According to Allison, (2000, 54), adolescents tend to heed to advice from peers than from teachers and parents. It is notably however, the relationship between a teen and his or her peers has great impact on their self esteem. According to Steinberg, (2001, 67), parent-adolescent conflict increases during puberty. Conflict has been found to be most evident in interactions between adolescent girls and their mothers and relatively between boys and fathers. Many adolescents feel that the parents do not understand them and that they have different lives and interests. They also feel that the parents cannot guide them properly through this ââ¬Å"stormyâ⬠period because they do not face the same challenges (Allison, 2000). In conclusion, there need to be a mutual understanding between parents and adolescents as puberty is a sensitive stage and needs to be handled with care by both parties. Only this way that both will minimize the unnecessary conflicts and promote understanding. Reference Allison, Barbara. (2000). Parent-adolescent conflict in early adolescence.

Using Social Media to Improve Food Safety
Using Social Media to Improve Food Safety Catalin Aricescu Abstract The Food and Drug Administration is an organization mandated to oversee the food and drug safety within the United States. On the other hand, information technology is growing fast and the agency needs to implement better means of communication especially with its participants from consumers to food sources. This study is a pilot research utilizing online survey to comprehend the feasibility of social media use for the improvement of the American food safety system. The results of the study show that more research is necessary as the social media users are mainly young and educated adults and they play an imperative role in the quick dissemination of preventive information, as well as food recall notices, in a manner that is likely to be heard or read widely. Therefore, it would be essential for the American Food and Drug Administration to incorporate social media into its main strategy. Introduction This pilot study was conducted to find out whether the food regulatory agencies such as the Food Safety and Inspection Service and the Food and Drug Administration should consider using social media as a means of improving the food safety system. According to Lang, Barling, Caraher, (2011) the utilization of social networking in organizations is emerging. On the other hand, Seo, Almanza, Miao, Behnke, (2015) affirm that the strategic use of social media in public firms is yet to be studied in great depth. According to Lang, Barling, Caraher, (2011), the exchange of food information and knowledge on food hazard is a form of vulnerability communication in food and safety procedures. Having considered the major characteristics of a food safety system, this pilot study aimed at proofing those effective and efficient food safety procedures are through the adoption of social media use by various regulatory bodies. The agenda may be attained by bringing together organizations and individuals representing various backgrounds. Background Public Policy and Food Safety According to the Consumers Union (2013), the Food and Drug Administration is an institution that is supposed to be a consumers watchdog. However, the agency has fallen short of its mandate. In the U.S., companies that supply processed foods often do not have the capacity to guarantee ingredient safety. Labs (2013) sustains that most of the American corporations do not even know the people or companies that supply their ingredients. Additionally, they do not know whether those suppliers ingredients are screened for microbes or other potentially harmful microorganisms. Recently, the main public policy strategic focus on food safety has been control. One of the strategies used to achieve control is through food recalls. Mayer and Harris (2012) say that food recalls often occur due to quality, physical or biological contamination. The Department of Agriculture, the FDA manufacturer, or the distributor can initiate a recall (Labs, 2013). For food recalls to occur fast, there should be a proper and effective means of message dissemination. Rapid information dissemination makes it easier to trace the data to know whether those affected have obtained the information on the withdrawal. On the other hand, Seo, Almanza, Miao, Behnke, 2015 state the Food Safety Modernization Act is trying to change food safety management from reaction to prevention. Lang, Barling, and Caraher (2011) also state that more groups are involved in the nations food safety program. For instance, the United States Food Safety Working Group implemented innovative strategies for the American food safety system. The FSWG is a group that is focused on the modernization of the food safety system especially through partnerships with regulatory agencies, the food industry, and consumers. The FSWG suggested a better route to freedom from fear of food safety to safe food through improved food systems. Consequently, the FSWG is based on three principles that are strengthening surveillance, prioritizing prevention and improvement of response and recovery. Using social media for food safety According to Mayer (2013), proper food recalling forms of communications are still in the infancy stage. Collier (2011) maintains that both subjective norms and attitudes have an impact on consumers and their intent to act in accordance with a food recall. Attitudes have a greater impact on the peoples ability to comply. Subjective norms and attitudes can be found on social networks. Consequently, social networks are imperative, according to Deasy (2012), and the role of social media is imperative in public policy. Mayer (2013) also suggests that regulatory bodies should emphasize the need to use social media. The use of social media is essential as it involves bringing together heterogeneous groups that form a social network. A social network is easier to coordinate when trying to identify food hazards as well as spread any form of food recall information (Karp, Baur, Atwill, De Master, Gennet, Iles, Kremen, 2015). Apart from using its website, the FDA could incorporate social networking strategies to enable it reach more consumers especially when required to recall certain products from a market. Taylor, and Sklamberg (2016) state that the FDA website offers information or announcements on all forms of recalls. Additionally, consumers can obtain e-mails after requesting to receive alerts on the website. Consumers that have food problems can report on the website, as the FDA has employed complaint coordinators within FDA district offices, to receive all forms of food complaints (Taylor Sklamberg, 2016). Furthermore, the conventional news outlets in the nation can broadcast recall information. On the other hand, with the increased use of social media, it would be important for the news media and regulatory bodies to use social networks as a means of reaching a wider audience in a short time (Deasy, 2012). The social networks allow people to obtain information in real time while people may hear of a recall from a television or radio long after it was issued. For instance, Plum Organics is an organization that has voluntarily used social media to spread information on food. Labs (2013) states that people hearing negative news, such as a recall, that has a direct influence on them, will try to obtain information from informal networks. Additionally, Taylor Sklamberg (2016) say that people are more likely to participate in spreading the information when they believe that the negative event affects them directly and understand that the consequences are serious enough to call for an action. Freberg, Graham, McGaughey, Freberg, (2011) affirm that the consumers are important agents in spreading the information about a food recall that would effectively work online. Social media influencers are an essential part of the social networking and could help in the dissemination of information on food safety. According to Freberg, Graham, McGaughey, and Freberg (2011), consumers who use the social media such as tweets, blogs, or other platforms to spread a negative event are known as social media influencers. Social media influencers play an essential role in the creation of noise in the system and on most occasions, their credibility is questioned due to misinformation or distortion of information. On the other hand, Lang, Barling, Caraher (2011) state that social media could still be used for the improvement of the food safety system. Social media use can be imperative in the food system. As Karp, Baur, Atwill, De Master, et al. (2015) sustain, the system could adopt a strategy that could help in the exploitation of the social networks, especially the social media. The social media may not only expand the systems versatile ability, but also improve its information dissemination to the public as well as take preventive role through tapping into diverse and unutilized resources on food hazard issues. Lang, Barling, and Caraher (2011) add that information and communication technological improvements helped develop ways through which the public agencies can learn on potential food hazards fast. The public agency still needs to coordinate communication to maintain the systems integrity. However, the planned utilization of innovative technologies allows coordination with regulatory interventions efficiently (Lang, Barling, Caraher, 2011). In spreading negative news, the social networks have been used extensively. Deasy (2012) maintains that new communication technologies can be utilized as an essential part of the food system, allowing all participants to exchange information on food safety. However, Mayer (2013) states that little effort has been used to involve consumers as participants in food safety. Research on social network use within corporations is still emerging. However, little information is available on its strategic use within public firms (Collier, 2012). The main disadvantage in the use of social media in public firms is information distortions. According to Taylor, and Sklamberg (2016), information disseminated online can be easily manipulated to a certain degree, which (Collier, 2012) states could bring about naÃÆ'à ¯ve learning. Online information is often asymmetrical. Consequently, individuals, and organizations could try to insert false information into the social networks. Lang, Barling, Caraher (2011) state that some companies may choose to alter the information with an aim of raising their competitions costs. Additionally, social media influencers may obtain an incentive to manipulate specific information to increase their popularity online. Taylor, and Sklamberg, (2016) say that efforts have been made to uncover such attempts but still no protection is available from such manipulation. Consequently, efforts to use the social network to pass information on food safety should be considered. Materials and Methods In the study, it was imperative to understand the current situation on public agency use of social media on food recalls. To comprehend the current situation within the United States it was important to carry out a survey, which was done between March 1 and March 9 2017. The survey aimed at focusing on the respondents attention. The main purpose of the study was to examine the responses on food recall. According to Deasy (2012), a food recall is the request to return an entire food production of a particular food product to the seller and it is usually done once safety issues are discovered. Social media use was common in this survey; consequently, the first question asked in the survey was: Which technological device do you use regularly (Computer, laptop, tablet or Smartphone)? The survey also includes two essential questions on product recall experiences. The questions were: Have you ever heard of a food recall? and How did you hear about the food recall? Seven demographic items followed the two questions. On the other hand, a participant that indicated she or he had never heard of a food recall, she or he automatically moved to next part of the survey. To obtain more information on personal experiences, the survey also included four scenarios that allowed the respondents to give more information. The first two circumstances dealt with the participants personal experiences particularly with food issues. The last two dealt with the recall announcements. Similar to the last section, anyone who has not experienced any scenario on food issues automatically moved to the next section. Table 1 Scenarios used in the survey First Scenario The experience of a main issue Have you ever eaten lunch at a restaurant and later ad a severe stomachache leading to diarrhea and forcing you to seek medical assistance? Second Scenario Experienced a minor problem Have you ever eaten at a restaurant and later had an upset stomach? Third Scenario Product you used recalled You bought a packaged lettuce and later heard its brand recalled on radio, television, newspaper or online Fourth Scenario Recall of a product you never used You heard a packaged lettuce recalled on radio, television, newspaper or online but you never use the brand The study was done on utilizing SurveyMonkey.Com, and it ended with three open-ended questions that included: Think of an occasion when you experienced a problem after eating at home or your favorite joint. Tell us the incident. How did you feel, what was your reaction, did anyone know of the problem? Did you seek medical attention? Did you change your eating or food buying pattern? Think of an occasion when you heard of a food recall. Tell us about the incident, how did you feel, what was your reaction, did anyone know of the incidence, did you change your eating or food purchasing patterns? Do you have any additional comments? Participants use of social media The participants showed their comprehension of food recall as well as having shared information on bad food experiences with coworkers, friends, and family through diverse social media platforms. The sharing of the information occurred under certain circumstances, for example, gravity of the issue or the person contacted. According to Lang, Barling, and Caraher (2011), social media use is common in age groups between 18-29 years and 30-49 years. In the results of the survey, the studied group was within the said age groups. In the study, we found that access to smart phones decreases with age while the use of computers, mainly desktop, increased with age. Additionally, the use of social media among the participants decreased with age, but varied in relation to the specific social media such as YouTube and Facebook, which are platforms common in all ages. In the study, 94.8% of the participants had heard of a food recall. Surprisingly, most of the participants had heard of the food recall through broadcast or print media. On the other hand, the younger participants especially those below 25 years had heard of the food recall on both broadcast media and social networks, while those above 25 years had heard of the food recall through broadcast and print media. The Concerns and Experiences of the Participants with Food Problems Most of the participants showed their concern for food safety especially on the participation of the government as well as organizations in monitoring the process successfully. The participants mentioned the need for Food and Drug Administration agencys participation in monitoring the food that people consume. The consumers also noted that there is an increased use of informal communication in food safety. On the other hand, they also expressed their concerns for the increased caution when using social networks as the main form of communication. Furthermore, they appreciated the need to obtain information on bad food. However, it should be mentioned that the person giving the information may have been self-diagnosing inaccurately. The participants mentioned the need to notify the authorities or the necessary bodies whenever there were food recalls after notifying friends and family. The participants had experienced the second Scenario more than the first scenario. Additionally, it was evident that the participants would tell others about the first scenario experience more than they would have in the second scenario. Moreover, more participants would have told others in the third scenario than they would have in the fourth scenario. Similar to previous studies, it was evident that more people were likely to tell others of a food recall if they used that product or had a severe experience from eating the food. The study also aimed at looking at any pattern on the responses. Therefore, Symphony software was used. On the other hand, a pattern did not exist as the participants mentioned different kinds of foods. Some of the foods mentioned included cereal, peanuts, beef, pizza, pork corn, fruit, chicken, lettuce, meat and chili, among others. The discovery of the patterns brought about the question: Who is more likely to inform others on a recall or experience on bad food using the social media? To obtain an answer to the question all participants that used any form of social platform for more than one of the scenarios were grouped together. The activity led to the conclusion that well-educated and young adults especially females were more likely to spread information of a food recall. Table 2 Gender Age Education Female 18-29 98 College graduate 85 Male 18-29 79 Advanced degree 87 Outcomes and Discussions The survey used a manageable sample of two hundred and fourteen respondents. Out of the 214, 212 responses were obtained from three universities. In the study, there were more female respondents than males. The respondents were aged between 18 and 29 years. All the participants were from diverse racial backgrounds, well educated, and were studying different courses at their universities. About 7.1% of the participants had attained their undergraduate education and were pursuing a higher level of education. More studies will be needed to obtain more conclusive information on the use of social networks for food safety. The results of this pilot study suggested that the utilization of social media as a modality of spreading the word on bad food would enable people to cope with the situation better, both cognitively and emotionally. The process would also help in the improvement of the food safety system. The differences that social media can create in improving food safety may be due to the fast dissemination of information using social media. Information sent by a relative, friend, or a close contact is more likely to be read, rather than general public information, spread through a newspaper. The outcomes of the study also suggested that social network users are generally well-educated and young adults. On the other hand, those with the ability to spread the word are not necessarily those with the most friends online. When aspects such as education, race, and gender are constant, the younger generation is more likely to use social networking platforms more than the older persons are. Additionally, females are more likely to use social media than males. Presently, people often use social networking platforms to socialize or spread information on events that they are not involved in or impacted by, directly. Upon hearing a recall of a familiar food product, females, unlike males, are more likely to pass information on the recall. Furthermore, an individual was more likely to spread the word on a recall after experiencing a severe food problem. On the other hand, those passing information were least likely to use social media as the platform to spread the word on a food recall. Therefore, agencies that need to improve their way of spreading information on food recall, need to adopt better plans, as well as formulate policies that ensure that the well-educated and young females are involved. Limitations of the Study This was a pilot study that was limited by time and as well as by using a specific demographic. The university students were the most appropriate. However, the study lacked diversity in the convenient sample size. University students may have a particular mindset on information technology. Consequently, it was difficult to obtain a more diverse view on the study. Moreover, despite obtaining results that were similar to previous studies, the sample size was not a representative one. The small sample size offered limited information on the topic. The study did not cover some aspects that may have influenced the participants use of social media, such as employment or income. Therefore, a large and diverse population would be more appropriate for future studies on the topic. Conclusion An outcome of this pilot research showed that due to the dynamics of social media, it is essential for food safety companies to use intelligence, sufficient resources, as well as good ideas to attain success in recalling bad food. The food agencies require having a strategy that offers a specific alertness in the use of social media information. For instance, the agencies may create their social media groups to manage the network and avoid misinformation. It would be important to form good relationships that are built on trust with the social media users. Furthermore, using hash tags when recalling food would help improve the spreading of the word. Agencies could as well collaborate with distributors, suppliers, grocers, manufacturers, restaurants and businesses that have websites to recall food products from a market, enabling better creation of trust. Consequently, using social media as part of the structured communication strategy would help improve the food and safety agencies. References Collier, M. (2011).

Zara Competitive Advantage Essay
Zara Competitive Advantage Essay There is a tough competition in clothing retailers. Who has a competitive advantage in clothing retailing will be the winner. Competitive Advantage refers to a companys profit and market share. Offshore supply is one of the processes, which is used generally by clothing retailers to accomplish low labour cost, as the apparel industry is still labour concentrated industry. The supply chain in the apparel industry is compound and lengthy. Barbee and Carlyle (1999,p.85-87) states that the supply chain encompasses all activities associated with the flow and manufacturing of goods, from raw material stage through to the end user, as well as associated information flow. The longer the supply chain the additional complicated it is to handle and the more a company relay on long-range forecasts. Challenging consumers and competitive retailing have produced stress to take action with multiple refreshes per season. The focal point is on replenishment of the exact styles, designs and colors that are selling well, whilst reducing, changing or abandoning those that turn out to be less popular than forecast. This decreases the difficulty of marking down the price of less popular clothing that fails to sell in the forecasted volumes. This trend, when taken to the extreme of compressing design times, multiple refreshes, coupled with very quick response from the supply base, and all done at low cost, describes the so-called Fast Fashion market.( Nebahat Tokatli,2007) Solomon and Robolt(2004) define Fashion as a style that is acknowledged by a great group of people at the given time. They also separate fashion into four catalogues: High Fashion (Couture) Moderate Fashion Budget Fashion Mass Fashion Fashion Life cycle contains the introduction acceptance, culmination and decline of the acceptance of a certain style. The Fashion cycle is not meant for long time, it changes in very short period. It is not compulsory that to introduce fashion and try to encourage consumers buying behavior before the decline stage is very important Fast Fashion as a conception helps to take the market and attract consumer earlier than other competitor by dropping the lead-time in supply chain. CONCEPT OF FAST FASHION: The techniques companies put into practice to reduce the time gap between designing the product and the time of consumption, through product and moving away from the considered seasonal basis called Fast Fashion. It examined that the expansion of fast fashion formulas become visible indicative from a production-driven market to a market-driven characterization of the apparel sector. It is not compulsory that fast fashion is a multipart process, which involves forecast, design, effective supply chain and transportation. Best Practice as the aptitude to do things in the well-organized manner. In other words it is a way of bring about a business function or process that is well thought-out to be greater to all other known methods (Kurian,2004). From past few years, organization attempted to build up their own supply chain strategies to continue to exist in such a ferociously competitive market. There are some organizations who come up with new concepts, which help them to gain competiti ve advantages over the rest of its competitors, such as Vendor Managed Inventory, Quick Respond manufacturing, Collaborative panning, Forecasting and Replenishment, Continuous Replenishment, Efficient Consumer Response, and Just-in Time Production. It recommended that a few particular best practices relating to the study of fast fashion are: Consumer Demand and Response Supply Chain Just In Time Quick Respond Forecasting and Continuous Replenishment Effective Distribution and Transport System In recent times, Zara, a most important international clothing retailer and break new ground of fast fashion principles, held in reserve almost half of its production in Spain and Portugal, earning the reputation of being one of the exceptions to globalization. Since the 1980s, the subsistence of such exceptions has been fueling an expectation that the manufacture of high-quality fashion garments and tailored suits would stay behind in the industrialized core. Here I return to this anticipation in the brightness of the modern seminal change in the culture of fashion from ready-to-wear to fast fashion, and description that the greater than before multiplicity and fashion capability associated with fast fashion, represented by Zara, have tilted the steadiness of competitive advantage towards, rather than away from, firms in partially industrialized countries. As a number of supplier firms in countries such as Morocco, India and Turkey have gained the competence to manufacture intricate ly worked high-quality garments with the compulsory elasticity and speed, Zara has turned to sourcing from these countries. ZARA The clothing sector is fundamental to the world economy. HISTORY Zara is subsidiary of Inditex group Spanish tycoon Amancio Ortega, owns the Inditex group and Inditex group owns the following brands such as Massimo Dutti, Pull and Bear, Oysho, Uterqà ¼e, Stradivarius and Bershka. Amancio Ortega is well known Galician fashion designer. According to Forbes ranking in 2009 Amancio Ortega was ranked as 10th richest man in world and top Ranked as a richest man in Spain. He was born on March 28, 1936 in Leon, Spain. He started working as delivery boy when he was 13 year old for a shirt-maker in Galicia. During the learning period of his carrier, he realize and learned the how product and cost changes. While travelling from manufacturer to the customer. In addition, the outcome was he become more focused on the importance of getting product directly to the consumer without middle man. When he become manager of local clothing company that time he found that only wealthy individuals could afford to purchase qualitative product. Therefore, Ortega started manufacturing his own product. He started buying cheaper fabric and selling good quality. Amancio Ortega founded his own company called Confecciones Goa at the age of 27, in 1963. Especially for fine bathrobes. After that, he continued manufacturing his own companies, then open first retail shop in 1975 known as Zara. ZARA started changing the design, manufacturing and distribution process to reduce lead times and react to new trends in a quicker way that was there plus point, called instant fashions. (Chiara Pirone,2010) Product Life Cycle The product life cycle ideally follows four main steps: Birth Growth Maturity Decline Generally, a typical Product Life Cycle Curve looks like the one given in the diagram where Sales decreases as the product moves over the time line. Zaras product life cycle also follows the four basic steps but the timeline of the product in the life cycle is very different. The organization operates in fashion industry and the changes pertaining to consumers taste is very high. Therefore, the life of the trend or design is of maximum 5-6 weeks. The following figure depicts the Zaras product life cycle. Key Factors of Success The organization focuses on following factors which are their success factors: They have short lead time i.e. the clothes stay in the store for less time which in turn provides them opportunity with more and more fashionable clothes. They manufacture clothes in low quantity and supply them scarcely which clearly states that the demand for the clothes is always high. Due to short lead time they can manufacture variety of choices, variety of styles and the success ratio increases. RATE OF PRODUCT CHANGES IN FAST FASHION FOR EXAMPLE ZARA: Zara can move from recognizing a trend to including clothes in its stores within 30 days, it means that Zara can identify and catch fashion trend. Catching fashion until the time it is hot is a clear happening at full prices and less discounts. Zara progresses in stair with its customers. Zaras machinery can respond to the statement right away and 51produce a response in conditions of a new style or a modification within 2-4 weeks. By dropping the amount manufactured in each style, Zara decreases its exposure to any particular product. The additional advantage of lower quantities is that if a style does not work well, there wills minimum stock to disposed during the season-end sale. Zara discounts only about 18% of its making, approximately half the levels of competitors. Instead of additional quantities per style, Zara produces extra styles, roughly 12,000 a year. So, that style sells out more fast and there are more new styles which are already waiting to come out. Re-orders are un usual the stores look fresh every 3-4 days. Fresh manufacture, moving in step with the fashion trend and updated regularly the ingredients are just right to create the sweet smell of success. Fast Fashion strategy in Zara: Zara typically has three sections women wear, men wear and kids wear. Most of its stores were located on downtown in big cities and were characterized by large windows with modest fittings. The company position itself as contemporary fashion of medium quality at a good price(Dandrea and Arnold,2002). In order to take extra market shares in such a full of rivalry situation, Zara introduced sequential policy of way of products: Convert latest fashion into products quickly and completely in order to satisfy consumers. Zara gets a competitive advantage by offering customer stylish clothes at inexpensive prices. A team of 200 designers is accountable for turning the latest fashion into products. The collection was converted every year with 11,000 dissimilar items. In order to collect the latest fashion information, the company employed a team of trend-spotters, who travel around the world in search of new designs (Dandrea and Arnold,2002). Thus, Zaras products are suitable for consumers vary different background and taste. Continue to introduction new products in small quantities, ironically in very high speed. New products were trialed at certain stores before entering full-run production to keep failures in the full range at a rate of 1 %( Dandrea and Arnold,2002). Reduce the usual cost associated with running out of any particular item. Because the company believes that empty racks do not drive customers to other stores while stimulating them to choose from new things. Furthermore, consumers will buy more and immediately due to rapidly changing trends. As a result, Zara has increased sales and avoided costly overproduction. Zara would plan a core collection each season, constituting approximately 50% of its forecast requirements. The remaining 50%, some 10,000 items, were sourced opportunistically according to demand trends during the season and could be at any store in two weeks. Some accessories such as handbags, jewelry, shoes, thus increasing sales. CONCLUSION Zara has up and down integrated all its processes. By applying a fast fashion strategy, Zara have accomplished a unexpected increase in profits and market share. By accept the fast fashion strategy the company has been able to decrease its make down sale to 15 to 20%. In contrast, the traditional industrys average is 30 to 40%. It has been examined to be the best way to help organization achieve competitive advantages. Such best performs help Zara establish an extraordinary supply chain and become the leader of in supply chain management. The practice of implementation of fast fashion has a few advantages Quick response, reduced account and forecasting, errors, shortened lead times and reduced transportation costs. In few years, as other main competitors such as GAP, HM , Marks Spencer (MS) have experienced a difficult period due to low income and with drawls from overseas markets, Zara has maintained a continual growth in sales.

Business/Industry Standards and Vocational Program Accountability :: Work Employees Employers Essays
Business/Industry Standards and Vocational Program Accountability Industry skill standards are already in place for many industries in the United States and in a number of statewide vocational education programs that serve those industries. The linkage of skill standards between industry and vocational education hinges on a competency-based approach to education and training. The effectiveness of this approach has been recognized by other countries, such as Denmark and Great Britain, that have adopted this process for establishing their industry skill standards. The National Vocational Qualifications (NVQs), developed in Great Britain, is one example of competency-based skill standards used to assess performance. This Digest looks at the motivations behind the initiation of industry standards and of national and state skill standards that would provide vocational program accountability. It examines the competency-based approach to the development of standards in relation to their effect on vocational education, drawing on reviews of the NVQs in Gre at Britain. Why Industries Set Skill Standards The gap between existing skills and desired or required skills is the basic impetus for the development of business/industry standards at all levels-local, state, and national. Many of these standards were developed over time, industry by industry, in response to competition from other industrialized nations and for the purpose of quality control. In the early 1970s, for example, automobile manufacturers were finding that graduates of automotive technology classes were lacking the skills necessary to work on cars with advanced technology systems. The public, losing faith in the quality of new car repair, were either not buying new cars or not buying cars made in the United States. Therefore, to improve worker competence, the National Institute for Automotive Service Excellence began to require that auto mechanics be certified (Fretwell and Pritz 1994). Over the years the professional associations of many industries have taken the initiative in setting skill standards. The American Institute of Certified Public Accountants, for example, has developed and implemented a national certification program through which it administers the Certified Public Accountants exam. The American Welding Society likewise administers tests for certification of workers in the welding profession. State licensing exams are used to certify workers in certain occupations as well, e.g., barber and chauffeur. On a national level, the Federal Aviation Administration has set standards for air traffic controllers, although in this case public safety is the primary force driving the action. The Need for Skill Standards in Vocational Education Most industry standards are established to improve worker competence and the products and services the workers provide.

fidel castro Essay -- essays research papers
The United States of America is a country that believes in democracy and has unfavorable ties with communist countries. The United States has tried for decades to improve relations with the countries that donââ¬â¢t practice democracy. History shows disagreements between the United States and dictators of these irreverent countries, disagreements that brought the world to the brink of nuclear war. The most recent of these confrontations involved three countries. United States of America, Cuba and the Union of Soviet Socialist Republic (USSR). Fidel Castro is a Cuban revolutionary, who took control of Cuba in 1959 and established a Communist dictatorship. Castro, who was born in Mayari, became the leader of an underground, anti-government faction. In 1956, he led a rebellion that won increasing popular support. Eventually Castro forced Batista y Zaldivar, who was the premier of Cuba to flee the country. Once in power Castro executed and imprisoned thousands of political opponents, nationalized industry, collectivized agriculture, and established a one-party socialist state. In the early 1960ââ¬â¢s Castro openly embraced Communism and formed close ties with the Union of Soviet Socialist Republic (USSR), relying on Soviet economic and military aid approving limited economic reforms that legalized some free enterprise. In Cuba, an estimated $1 billion in U.S.-owned properties were seized in 1960. The Castro government seized oil refineries, sugar mills, and electric utilities owned by th...

Philosophy â⬠Free Will vs. Determinism Essay
The dialogue between philosophers over the existence of free will versus the inevitability of determinism is a debate that will always exist. The discussion centers around the true freedom of humans to think and act according to their own judgment versus the concept that humans are intrinsically bound by the physical laws of the universe. Before I enter this chicken and the egg debate I need to quantify my terms: Free will is defined by the great philosopher, St. Thomas Aquinas as ââ¬Å"vis electivaâ⬠or free choice. It is the ability of man to contemplate and judge the effects of the actions he is about to take. ââ¬Å"â⬠¦But man acts from judgment, because by his apprehensive power he judges that something should be avoided or sought. But because this judgment, in the case of some particular act, is not from a natural instinct but from some act of comparison in the reason, therefore he acts from free judgment and retains the power of being inclined to various things. â⬠(Aquinas. Suma Theologica) Determinism is a complex notion but is best described by David Hume as the notion that something cannot come from nothing and that all actions have causes preceding them. ââ¬Å"I conceive that nothing taketh beginning from itself, but from the action of some other immediate agent without itself. And that therefore, when first a man hath an appetite or will to something, to which immediately before he had no appetite nor will, the cause of his will, is not the will itself, but something else not in his own disposing. So that whereas it is out of controversy, that of voluntary actions the will is the necessary cause, and by this which is said, the will is also caused by other things whereof it disposeth not, it followeth, that voluntary actions have all of them necessary causes, and therefore are necessitated. â⬠(Hume. Liberty and Nessessity. ) Philosophy and world religion alike were born of the same origins. Each of the two ancient disciplines arose from the quest for the answers to lifeââ¬â¢s ominous questions. These human questions, archetypical to people of all geographic locations; where did we come from; why are we here; where do we go when we die; unite us as a race. It is no coincidence that each religion and theology from all four corners of the earth tackles these black holes of human logic. Each religion carves their own individual explanations of these unanswerable questions into their core belief systems, each one centrally different than others. However, they all share one common thought; each shares a belief in an afterlife determined by the choices made in life. Free will is the common denominator in all world religions, because all share the essential concept of morality. The widespread acceptance of the concept of morality implies that there is a choice to be had at each and every juncture or life. The choice comes from recognition of good and evil. For good and evil to exist, then there has to be the ability to decipher between the two and also decide to accept one over the other. The existence of morality alone proves that free will exists, because without the freedom to choose right or wrong in any given situation there would be no qualitative measure of the ââ¬Å"rightnessâ⬠or ââ¬Å"wrongnessâ⬠of ones actions. David Hume comments on the origin of morality and its place in our everyday decision making processes, ââ¬Å"Only when you turn your reflexion into your own breast, and find a sentiment of disapprobationâ⬠(Hume.Treatise of Human Nature). In other words, there are no outside stimuli that can decipher good from evil; the line can only be drawn by internal thought. Hume was a naturalist in that his vision of the world and therefore stance of philosophy was based directly through the experiences of the senses. His stance on many issues directly originated from his ability to experience it with the five senses, and on the subject of morality he takes exception. Even he recognizes the existence of morality in everyday life, even though it cannot be explained through the lens of the senses. It would seem that moralityââ¬â¢s acceptance must therefore prove that free will exists, but there is one essential school of thought yet to weigh on this topic; science. Science was the latest bloomer of the three major disciplines of existential explanation and in the post modern era is becoming more and more popular. As the world becomes further secularized and the reaches of scientific logic continue to exceed their grasp, many of the worldââ¬â¢s intellectuals identify ââ¬Å"truthâ⬠on a scientific scale. Science does not support the theory of morality, because it canââ¬â¢t be proven to exist. The notion of ââ¬Å"free-willâ⬠, something which world religion and philosophies alike recognize as a fundamental part of our human anatomy, is called into question in a few simple and logical ways. Science supports the theory of determinism as the only logical explanation of the unfolding of the actions of our lives. First off, science has recently developed the discipline known to us as physics, in which the laws of the universe have been defined. In the short time in which humans have been graced by the scientific understanding of the laws of the universe, human kind has yet to fully step back and contemplate the magnitude of this discovery. In generations past, humans believed that we were made special with ââ¬Å"free willâ⬠, but now we know that like all things in the universe we are subject to the physical laws. This is a huge step forward in rational thinking because it allows us to understand that our previously God given concept of ââ¬Å"free willâ⬠was really a result of a lack of understanding of the deterministic laws of the universe. For instance a law as simple and commonly accepted as ââ¬Å"gravityâ⬠challenges the idea of free will. Gravitational pull determines that no matter the size of an object, once separate from the surface of the earth will be dragged back down at the same force every time. This is a simple concept that we take for granted, but it works in the free will v. determinism argument. We are ruled by gravity, and therefore all of our lives activities answer to it. We canââ¬â¢t choose to jump off a building and float in the air because weââ¬â¢ll be pulled back to the ground to our imminent deaths. We canââ¬â¢t choose to stay younger and keep our skin tight to our faces because gravityââ¬â¢s long-term effect causes our skin to droop down towards the ground. The choices I just listed may seem farfetched to some, however, if we examine the notion that we have ââ¬Å"free willâ⬠in the empirical sense of the word we see that not all of our decisions are controlled by us, and that we fall victim to the tyrannical rule of the physical laws of the universe. We arenââ¬â¢t truly ââ¬Å"freeâ⬠to create our own actions in life. Albert Einstein offers a particularly apt synopsis, ââ¬Å"Everything is determined, the beginning as well as the end, by forces over which we have no control. It is determined for the insect as well as the star. Human beings, vegetables, or cosmic dust, we all dance to a mysterious tune, intoned in the distance by an invisible piper. â⬠(Albert Einstein) The rule of physical law aside, which hinders us from truly being ââ¬Å"freeâ⬠to choose our own actions in life, is a much more simple scientific argument that dispels the notion of free will. For example: Say a 20 year old man murders another man in cold blood. They have no affiliation, no prior knowledge of who each other is, or reason to dislike each other. Man A walks up to random Man B and shoots and kills him. Was this action of Man A a result of ââ¬Å"free willâ⬠? To examine the notion fully you need to look at his action coming from two sources. Either Man A was born with the moral flaw to allow himself to find killing another human acceptable, or that Man A was influenced during the course of his life by interactions and actions of others and came to that conclusion based on his own experience. There is no other explanation for Man A to willingly choose to open fire on Man B and kill him. If we look at the first option, Man Aââ¬â¢s natural moral compass was skewed, allowing for him to conceive the notion that killing another is okay. This speaks to the determinant nature of our chemical makeup. Its possible his DNA made a mistake coding somewhere and he developed overtime and understood that killing another is ââ¬Å"wrongâ⬠or maybe that his entire sense of ââ¬Å"right from wrongâ⬠was skewed inside his mind. This would lead Man A to lead a life normally on the outside, and yet without regard for consequence, open fire on another man and kill him as easily as he could have held a door for him. This is the idea that he naturally had the capacity to kill, and that he could not control it. Eventually one of his animalistic impulses would finally stick and heââ¬â¢d be in the right place at the right time, and that it was only a matter of time until he killed someone. If you donââ¬â¢t subscribe to that theory and believe that he chose to kill Man B that day, try and consider that the results will still be pre-determined. If Man A killed Man B due to his choice, then his own ââ¬Å"free willâ⬠and judgment that he finds reprehensible to kill another man canââ¬â¢t be attributed to truly ââ¬Å"freeâ⬠will of choice. Not every human kills others as part of their natural lifestyle, as they might kiss or mate with another. In fact a very small percentage of people in the world murder other humans, and this begs the question of why? What makes this small percentage of people ââ¬Å"chooseâ⬠to kill another person? The answer is that if they choose to do it, and they werenââ¬â¢t previously miswired so as said in the prior paragraph, then they must have been influenced by their surroundings. When Man A was six years old he didnââ¬â¢t choose to murder Man B, the events of his life led him to make this decision about whether or not murder was okay. This is yet another reason that he wasnââ¬â¢t truly free to choose; outside influence hinders the ability to choose freely. Whether he was abused, molested, lost a loved one, or just plain fed up with the monotony of everyday life in society, something pushed him over the edge. Something allowed for him to justify his actions; that something is outside influence. This deterministic train of thought explains why people do what they do, but not when. What makes us actually hit the point of no return, or when will the right opportunity hit the right mood leading the right action? (In our example the murder of Man B) The paradox between ââ¬Å"free willâ⬠and ââ¬Å"determinismâ⬠exists because of the influence of the different schools of thought. If one aligns his personal truth based on religious fervor, then an understanding of ââ¬Å"free willâ⬠can exist logically and on the other hand if one bases his logic around science then ââ¬Å"determinismâ⬠seems to be the only answer. So where does that leave philosophy, the great bridge between the two polarized schools of thought? It leaves philosophy somewhere in the middle, examining the validity of both sides of the argument, and helping to shed light on the debate over whether or not we truly are free to make a choice or if we are merely floating along the currents of the universe. Personally, Iââ¬â¢m lost somewhere in the middle, hoping that the answer to this time-old question will be revealed. Works Cited: * Aquinas, St. Thomas.
