Technology And Television Child Obesity Essays (803 words)
Innovation And Television: Child Obesity Innovation and Television: Child Obesity The offspring of today are getting increasingly large, for the way that they are acquiring lethargy. They are investing more energy before the TV then they are getting their day by day work out. Their developing bodies need exercise to lose child fat before it gets the chance to be a difficult issue. The development of innovation has framed a significant effect on the corpulence of the present kids. This innovation has subbed ordinary youth play practices with PC games that require less physical exertion. In view of innovation in the present society the issue with youngster heftiness has gotten enormously strengthened. To begin with, what is youngster weight? The term kid corpulence implies a ?youngster is an individual among birth and pubescence and hefty is incredibly fat: corpulent?(The American Heritage Dictionary 265,856). This infection is caused because of an absence of activity and over-eating by a youngster. Kid corpulence can cause numerous clinical issues for a kid that experiences such a malady. Obesty is a far reaching malady that is deteriorating as innovation increments. Moreover, clearly the absence of activity has a significant part to do with kid corpulence; researchers reprimand the TV for a substitute to open air sports. Children are investing more energy stare at the TV than they are doing physical exercises. ?The discoveries firmly bolster the thought that the most significant way of life factor in youth stoutness is TV watching?(Monmaney). The TV breathes life into the kid's creative mind, giving them diversion to manage without the running and practicing of outside games. The more TV a youngster watches the more corpulent the kid will get. Next, the issue is getting so wild that the administration will need to begin getting included. Satcher and Shirley Watkins, the undersecretary of agribusiness for food, nourishment and purchaser administrations said that, 'television expands corpulence, smothers imagination and abbreviates capacities to focus among youngsters' (Bauder). This is their explanation behind joining the crusade for a TV-Free America. It is evaluated that a hefty youngster watches a normal of four hours and nine minutes of TV every day. That is four hours that a youngster could be holding with their family or making a move in some physical action. Therefore, issue with kid corpulence begins as youthful as early stages. In the event that the youngster's folks don't pressure practice the kid will locate an elective method to involve their time. For instance, playing a game cartridge as opposed to shooting bands or flying a kite. The game cartridge furnishes inexpensive diversion with next to no wellness included. Ross Andersen prescribes that guardians discover options in contrast to sitting in front of the TV for their kids (Joseph). A parent should do anything conceivable to get their children from the TV. Ether by making day by day arrangements with coordinated interims constraining the measure of TV the youngster can watch or marking them up for YMCA sport exercises. Regardless of whether the parent has a bustling work routine, make time to profit the kid. In spite of the fact that, there are various measures of doctor prescribed medications for youngster heftiness, the side influences are unreasonably hazardous for the more youthful kid. The most straightforward approach to comprehend this notable infection is by halting the issue before it begins. ?'In the event that you can intercede with overweight kids before they are completely developed, you can frequently assist them with developing into their weight and keep them from turning out to be overweight grown-ups. Some overweight kids don't have to shed pounds as much as they have to put on weight at a more slow rate.'? (Discroll) Proceeding onward, a few youngsters don't have to get more fit, however need assistance developing into the weight they as of now have. They can utilize help to slow the rate at which they put on weight, making it simpler for them to develop into it. Also, the wellbeing hazard looked by youngsters with the sickness of kid stoutness is massive. ?In excess of 70 percent of all cases endure into adulthood?(Mellin). Stoutness during grown-up years is related with expanded paces of illnesses, for example, hyperinsulinemia, coronary illness, angina, atherosclerosis, different tumors, orthopedic issues, and gout alongside numerous other present moment and psychosocial results of corpulence in kids. In this manner, with the innovation in the present society the issue with kid corpulence has generally heightened. The administration of weight and overweight in kids is an

How Dopamine Controls the Brains Reward and Pleasure Centers
How Dopamine Controls the Brains Reward and Pleasure Centers Dopamine is one of the feel-good hormones. As defined by Encyclopedia Britannica, itâsâa nitrogen-containing organic compound formed as an intermediate compound from dihydroxyphenylalanine (dopa) during the metabolism of the amino acid tyrosineâ.The major function of dopamine in our brain is that of a neurotransmitter in basal ganglia, corpus striatum and the substantia nigra.High levels of dopamine in your brain will make you feel pleased, happy, most importantly, rewarded for something youâve accomplished.Thatâs why dopamine is often mentioned together with serotonin and oxytocin. All these chemicals have a positive effect on our mood and behavior.In this article, weâre going to discuss how dopamine controls the brainâs reward and pleasure centers.THE POSITION OF REWARD AND PLEASURE CENTERSPeople function on the basis of rewards, pleasures, inhibitions, fears, and interplays between these states of mind. The levels of chemicals inside our brain related to each o f these feelings vary due to different daily situations that we experience.Whatâs for sure is that a high level of dopamine is closely connected with rewards. To be more precise, every time when youâre expecting a reward for something youâve done, the dopamine levels rise.This increase comes as a result of certain processes in the pleasure and reward centers in your brain.In a nutshell, the brain reacts in a certain way when itâs exposed to rewarding stimuli. These reactions lead to the increase of dopamine levels, which in turn causes feelings of satisfaction and happiness.The elements of the reward and pleasure systemWhat also plays an important role in the production of dopamine in the brain are two main dopamine pathways: the mesolimbic dopamine pathway and the mesocortical pathway. The former is the pivotal point in the entire brain reward system.At this point, itâs also important to highlight the functions of the nucleus accumbens and the ventral tegmental area (VTA) . The VTA is one of the key dopamine-producing parts of the brain. The nucleus accumbens, on the other hand, is one of the major centers for motivation and reward in our brain.The mesolimbic dopamine pathway goes from the VTA to the nucleus accumbens. Since it connects a dopamine-producing area with one of the reward centers, itâs one of the most important pathways for distribution of dopamine throughout the brain.On the other hand, the mesocorticaldopamine pathway leads from the VTA to the cerebral cortex. This area is also part of the reward system.In the study The Orbitofrontal Cortex and Reward, Edmund T. Rolls, PH. D, explains that the feelings of reward for pleasant tastes and smells are placed in this part of the cortex.To cut a long story short, two dopamine pathways, one dopamine-generating center and several areas that cause the feelings of reward and satisfaction make the reward and pleasure system in our brain.The reward stimuli and experimentsAlthough scientists knew for ages that people reacted to many stimuli in a conditioned way, it was only in the 1950s that they were able to prove that point.So, in 1954, psychologists James Milner and Peter Milner of McGill University conducted an experiment on rats in which they discovered the reward centers in the brain.They placed electrodes inside ratsâ brains, after which they used a lever to create electrical stimuli inside the animalsâ brains. Each time they would press the lever, the same area of the brain got stimulated. This was interpreted as the feeling of reward for their effort and success.The more time the lever was being pressed, the higher level of stimulation the rats would receive. In the notes from this experiment, it was written down that one rat got so hooked up on the stimuli and the feeling of reward for pressing the lever that this particular animal pressed it more than 7500 times.Since the rats in this experiment kept repeating the same action over and over again to stimulate t he same area in the brain, Milner and Old concluded that the animals were enjoying the entire process.Later on, other scientists took the plunge to additionally clarify the findings of these two scientists so there were some more detailed discoveries regarding the reward areas in the brain.To be more precise, scientists found that the area around the medial forebrain bundle is one of the most sensitive parts of the brain related to rewards and pleasure.A huge set of nerve fibers between the hypothalamus and the VTA, the medial forebrain bundle turned out to be so sensitive for the rats that they would rather keep pressing the lever than eat food. Due to its high sensitivity, this bundle generated a more pleasant feeling than a meal.In the video below you can see a concise presentation on the rewards system in our brain. THE MESOLIMBIC PATHWAYWeâve already mentioned that the mesolimbic pathway connects the VTA and the nucleus accumbens. The former is located in the midbrain and the latter is placed in the ventral striatum in the forebrain.One of the dopaminergic pathways in the brain, this neurotransmitter highway produces and emits dopamine. The mesolimbic pathway consists of projection dopamine neurons, made of axons, which cover this entire pathway. The production of dopamine starts in the dopamine neurons, where dopamine-synthesizing enzymes are produced.These chemicals travel via axons to synapses, which is where the lionâs share of dopamine is synthesized.The mesolimbic pathway and motivationAs the dopamine is produced, itâs released into the nucleus accumbens. The level of dopamine in this pleasure and reward center regulates the level of motivation and desire for rewards in our brain.As such, it also plays a certain role in our subjective feeling of pleasure. Hence, when the level of dopamine is high in the nucleus accumbens, people feel satisfied, motivated and fulfilled.When they get the reward for something theyâve done, the dopamine level re mains high, extending the feeling of satisfaction and exaltation.The dysfunctionality of the mesolimbic pathwayApart from learning and motivational salience, the role of the mesolimbic pathway is to control fear and some other processes in the brain.All these feelings are in some way connected with the feelings of reward and pleasure. We all get accustomed to a certain level of dopamine in this part of the brain during our lifetime.Because of that, the dysfunctionality of the mesolimbic pathway and the subsequent decrease in the dopamine levels can force us to seek the feeling of reward from other sources.Simply put, when thereâs not enough dopamine in the mesolimbic pathway, the brain tries to make up for the lack of this neurotransmitter and to stimulate the neurons responsible for pleasure and rewards.Since we need to be motivated to get things done and lead normal lives, when the centers for motivation and reward arenât properly stimulated, it can lead to demotivation, depre ssion, and schizophrenia.You can read more about different levels of motivation in the article âMaslowâs Hierarchy of Needs: Definition, Explained, Exampleâ on our website.Further, when the production of dopamine and the functionality of the mesolimbic pathway are deregulated, people can develop addictions or other disorders.This is why people become addicted to gambling, drugs, sex, or any other activity that generates high dopamine levels and that intensive feeling of satisfaction and pleasure.Dopamine sends rewarding signalsHowever, itâs wrong to think that dopamine itself is addictive or that it can make you feel good on itself. Being a neurotransmitter, it rather signals that something pleasant is about to happen.In the article âNo, Dopamine Is Not Addictiveâ, published on the Psychology Today website, clinical psychologist David Ley, Ph. D explains that dopamine is the announcer of the forthcoming pleasure. Also, it helps us learn and memorize things that cause ple asure and the release of rewarding chemicals in our brain.For instance, when youâre about to have your favorite meal, the dopamine levels increase because your brain remembers how pleasant it is to eat that particular food.In line with that, the mesolimbic pathway is here to inform all the areas situated next to it, as well as the nucleus accumbens that something good is going to happen to you soon.THE MESOCORTICAL PATHWAYThe second most important dopaminergic pathway in our brain, the mesocortical pathway leads from the ventral tegmental area in the midbrain to the prefrontal cortex.It delivers dopamine to the dorsolateral frontal cortex. This area of the brain plays a major role in emotional response, planning, abstract reasoning, motivation and cognitive flexibility and control, and other executive functions.Because of that, itâs extremely important that itâs connected with one of the four dopaminergic pathways.Being connected with the midbrain centers related to stimuli an d rewards, the prefrontal cortex is regularly fed with the chemical information related to these feelings.The malfunctioned mesocortical pathwayIf we suffer from schizophrenia, psychoses, or anxiety, there might be flaws or abnormalities in the functionality of the dopamine stream from the mesocortical pathway to the dorsolateral frontal cortex.A lower level of dopamine in that pathway can result in feelings of apathy or lethargy, as well as the lack of willpower.This is so due to the hypoactive stimuli of the prefrontal cortex. Because of that, D1 receptors donât receive enough stimulation, which is also why people with low dopamine levels can suffer from the aforementioned symptoms and other problems in cognitive processes.In other words, when the prefrontal cortex doesnât receive enough dopamine, many other parts of the brain subordinate to it wonât be notified on the potential rewarding experience weâre about to have. When they donât receive that information, they canâ t develop the feelings of exhilaration and excitement prior to the forthcoming reward.As a result, such people can look and feel isolated and depressed, simply because they have low dopamine levels and their brain cannot reach that pre-rewarding state.THE ROLE OF NUCLEUS ACCUMBENS Situated in the basal forebrain and part of the basal ganglia, the nucleus accumbens (NAc) is the key feature of the ventral striatum. The main parts of the nucleus accumbens are the core and the shell. Both of them are important in the full functionality of this part of the brain.The most important role of this brain element is its involvement in the reward process. To be more precise, this part is the end point of the reward circuit that starts in the VTA.When weâre about to do something that our brain recognizes as pleasant, weâre going to experience a feeling of reward and pleasure.In such a situation, the VTA generates dopamine hormones and other substances so as to announce that thereâs goin g to be a reward. Those hormones are then sent to the nucleus accumbens. The end result of this process is that the level of dopamine in the NAc increases.This part is also a vital output unit for the nervous system. In a nutshell, neurons from the nucleus accumbens travel to the basal ganglia and the ventral pallidum (VP). The latter emits neurons that go to the dorsal thalamus, where this pathway diverges to the striatum and the prefrontal cortex.Scientists used to believe that the NAc had an important role in the reward-mediating process. Because of that, it was often connected with various addictions and their development.Nevertheless, in-depth analyses about the connection between the nucleus and rewards led to the conclusion that dopamine doesnât only increase prior to a reward, but it also reacts to negative stimuli.For instance, if your brain memorized an unpleasant taste, when it gets stimulated by that very taste again, it dopamine levels will rise, as a warning. Without the nucleus accumbens, it wouldnât be possible.You can find out more about the entire reward pathway and its components in the video below. THE ROLE OF VENTRAL TEGMENTAL AREA One of the most important parts of the entire reward system, the ventral tegmental area (VTA) is situated in the midbrain, close to the substantia nigra.The source of many different sorts of neurons, the VTA is most important for its role in the production of dopaminergic neurons. These transmitters are sent from the VTA to different parts of the brain.Due to the character of the chemicals it produces and sends around the brain, the VTA has an important function in establishing a particular type of behavior.The reason why this part is usually mentioned with the substantia nigra is the fact that these two elements are two key dopaminergic parts of the brain.And while the substantia nigra is closely related to the putamen and the caudate â" the two parts of the striatum â" the VTA is the source of the mesoc ortical and mesolimbic pathways. The former ends in the cortical parts, while the latter finished in limbic regions of the brain.The aforementioned increase of dopamine in the NAc when the brain is stimulated either by affirmative or aversive stimuli has its roots in the VTA.Namely, the release of dopamine and its projection through the mesolimbic pathway are both triggered by the neurons placed in the VTA.All this leads to the conclusion that the VTA is an integral part of the entire rewarding system. Because of that, some experts consider this part of the brain an important element in the addiction-developing process.Apart from addiction, the VTA is often cited as an important factor in understanding and treading other cognitive disorders, among which schizophrenia is the most prominent one.This is mainly so due to the fact that this disorder is connected with high dopamine levels.Since dopamine production is activated by dopaminergic neurons in the VTA, thereâs a correlation be tween schizophrenia and this part.On the other hand, low dopamine levels can lead to ADHD (attention-deficit hyperactivity disorder).Since the VTA has a huge role in dopaminergic projections, which affect numerous cognitive processes in our brain, the VTA is included in both regular and abnormal mental processes.To cut a long story short, when the VTA doesnât function properly, the entire brain will have difficulties in maintaining all the functions necessary for normal life.THE LACK OF DOPAMINE â" ISSUES Weâve already discussed the most frequent disorders connected with either the lack or excess of dopamine, such as apathy or schizophrenia.However, these arenât the only issues that can come as a result of unbalanced dopamine levels. Since most problems occur when dopamine is low, here are some symptoms that your dopamine levels might not be on a satisfied level.Your dopamine levels might be low if you feel frequent tremors or cramps in your extremities, as well as stiff mus cles. Whatâs more, these symptoms are often indicators of Parkinsonâs disease.Thatâs why they require special attention and testing so that you start with the right therapy as soon as possible.Further, people suffering from dopamine deficiency could suffer from constipation, the loss of appetite or fatigue.All these symptoms can occur as the result of low dopamine. Simply put, when the pleasure centers in your brain donât feel that the reward is coming, in form of a pleasant taste or smell, the centers that control your appetite and the digestive system wonât be inspired to eat at all.Similarly, if you feel chronic exhaustion and low libido, your dopamine levels might not be as high as necessary for normal everyday life.This connection is similar to the relationship between dopamine and food â" if the pleasure centers arenât notified that thereâs going to be a reward for something youâd initially like to do, there wonât be any chemical support for the action in qu estion.Closely related to these symptoms is the lack of self-esteem and motivation to do things in your life. Itâs important to know that motivation isnât only a psychological element, but itâs deeply rooted in the chemical processes in our brain.Dopamine is one of the major substances of the entire motivation system, which is why low dopamine levels will lead to weak motivation. If there is no chemical announcement that the reward is coming, you wonât be motivated to do what youâre planning.Increase dopamine levels naturallyIf youâre feeling any of the aforementioned symptoms, you should visit a doctor and check your dopamine.Depending on their policy, theyâll either prescribe some dopamine supplements or recommend how to increase dopamine levels naturally.For starters, you should change your diet. Instead of saturated fats and sugars, try to take in higher amounts of protein and fiber. They contain amino acids that will help your body produce more dopamine.Tyrosine i s one of the most important amino acids for the production of this neurotransmitter. Beef, turkey, soy, eggs, dairy products, and legumes are all rich in this amino acid, so include these ingredients to your menu.Moreover, include probiotics in your daily routine. The brain and the stomach are closely related, which is the gut plays a major role in many chemical processes that affect the brain.In the study âThe Gut Microbiome and the Brainâ conducted by Leo Galland, MD, the founder of Functional medicine, claims that some bacteria in the gut enhance increasing dopamine levels in the brain.Itâs also important to work out regularly in order to increase dopamine. Moving is one of the primary abilities that people have, which is why at least 20 minutes of physical exercise daily improves numerous physical and physiological functions.Since continuous workout increases endorphin levels, it also improves your mood. When youâre in a good mood, your motivation is already higher. In t urn, dopamine rises, as well, resulting in the better balance of this neurotransmitter.When youâre physically active, youâll get more sleep, which is also a prerequisite for increasing dopamine levels.Last, but not the least, you can listen to some inspiring music that you like or binaural beats.The latter can improve the overall state of your mind, including the levels of transmitters.You can listen to some binaural beats in the video below. CONCLUSIONDopamine is one of the most important chemical elements of our brain. If itâs too low, we donât feel enough motivation for many things that make the quality of life. In the case of high dopamine levels, we can develop some disorders that will cause too intensive behaviors.What you can do to enhance the functionality of the nucleus accumbens and the ventral tegmental area and the overall levels of dopamine is eat well, get regular sleep, and work out regularly.If your dopamine balance is severely damaged, you should go and see the doctor who will help you regain the balance.Only normal dopamine levels will notify the brain to send reward signals to the pleasure centers and keep us functional and well-prepared for everyday life.

Advanced system analysis Free Essays
Many questions have been asked regarding what exactly systems engineering is and what the roles of systems engineers are. The questions mainly asked are if systems engineers perform general works or whether they specialize in specific tasks. The question of whether system engineering is the overall process of managing a project or a life cycle of roles such as program verification and validation. We will write a custom essay sample on Advanced system analysis or any similar topic only for you Order Now It is even worth to either define the system engineering process as an attitude or a discipline. This research will entirely look at the many definitions of systems engineering and the roles that are played by the system engineers. The research will mention eleven roles that are executed by system engineers and some of these roles will be described as life cycle rules while others will be described as project management roles and others will fall on either group. The paper will also try to distinguish the roles played by system engineers from those played by subsystem engineers. The Role of a System Engineer at the System level Many companies have system engineering departments and the departmentââ¬â¢s main role is to check the product delivered to the customers. Engineers who work on the subsystems (elements that combine to form the whole system) are not always referred as system engineers but are referred with names according to the subsystem they work on; for example a software engineer will work on developing the software subsystem of the whole system, a Hardware engineer deals with the hardware subsystem of the whole system. Requirements owner role This role requires the system engineer to translate the customer needs into a set of well structured requirements which aid in the development of the whole system and the subsystems. The requirements should capture the external interfaces and ensure that the functional architecture of the needs is captured as well (Roger1985). The role of the subsystem engineer at this point is to assess the impact of the requirements to the system as a whole and its subsystem and decide which requirements should be modified. Subsystem specifications creation and maintenance is the other role that is handled by the subsystem engineer with various factors playing a major role in the formality of determining the requirements required. The factors include the degree of the customer needs, the companyââ¬â¢s culture and the size of the project. Large projects mainly involve intense communications processes with formal processes (Roger 1985). System designing role At this role the system engineer will create the high level system architecture and then select the its major components. The system designer (Subsystem engineer) then investigates the possible ways of developing the system from pieces he possesses. He then compares those ways with the system requirements to ensure that the systemââ¬â¢s functionality captures all the requirements stated in the previous stage. The system designer fine tunes the design and also describes in detail the needs of the other lower subsystems. And finally he confirms if the subsystems can meet the specifications available or if it is possible to develop them. Mainly the role of system engineers at this stage will be to focus on the architecture, high level design, integration and verification of the subsystem. The lower level development of the subsystem will be the role of the system designer (Matty1997). The system design role comes after the requirement engineer has come up with the requirements and the functional structure. The two tasks work together in the selection of the subsystems and the explanation of the subsystem requirements. System analysis role à System analysts (subsystem engineers) at this stage try to confirm if the system designed meets the system requirements stated. The things to be analyzed will be system throughput and output, memory usage, and the system response. The work of the system engineer is to model the complex parts of the system to investigate if they are able to work well and interface them with the outside world. Modeling will also assist the system engineers to understand the operations of the system. The system engineers carry out such modeling with various powerful simulation tools. The type of project will determine the extent of analysis to be carried out with complex and risky projects requiring higher levels of analysis. Validation and verification role So as to ensure that the developed system meets the stated requirements, validation and verification engineers develop a verification program and sometimes the system engineers also come up with the test plans and procedures and determine whatââ¬â¢s supposed to happen during an event. Verification and validation engineers are responsible for answering such questions and should also be able to predict behaviour of the events in advance. Verification and Validation engineers are also able to fully understand the system design so that they are able to respond to any anomalies that may occur and incases of emergencies are aware of the experts to call (Fisher1992). The role of the verifications and validations depends on the organizational structure; in some organizations a system test group performs these roles while in others the roles are performed by both a group of system engineers and the system test group. Logistics and Operations (LO) Role. System engineers at this face will demonstrate to the customer of how the system will operate. They are also asked questions by the customers regarding the operation of the system, and will also settle any anomalies that will arise.

Ethics and Starbucks free essay sample
Introduction Marketing ethics refers to the moral principles concerning acceptable and unacceptable behavior related to the operation of marketing by business people (Barronââ¬â¢s Educational Series, 2007). In order to obtain higher profit, some of the companies may violate business ethical values. Background Mattel founded in 1945 is one of the largest toy companies in the world (Fortune, 2008). Although Mattel is a major toy company, there are many unethical issues found. Firstly, Mattel`s products contained lead paint and tiny magnets that could be swallowed (Mauro, 2007). Secondly, Mattel recalled toys frequently as there were five recalls in less than a year (Mattel. com, 2010). Thirdly, the packaging of Mattel`s product contributed to rainforest destruction (Jakarta, 2011). According to the American Marketing Association (AMA), these activities are unethical and violate 3 ethical values including responsibility, honesty and citizenship. Responsibility For responsibility, Mattel failed to accept the consequences of our marketing decision and strategies. Mattel did not recognize their special commitments to vulnerable market segments such as children who may be disadvantaged. First of all, on August 14 2007, Mattel`s product, the ââ¬ËSargeââ¬â¢ cars, was discovered with lead paint and tiny magnets which are harmful and dangerous to children. Although the product was recalled, some of the products which are claimed passed still contain lead paint. However, Mattel minimized the impact of the use of lead paint. In fact, lead is toxic if ingested by children and there is no safe level of lead in them according to Dr. John Rosen, a lead poisoning specialist (Consumer news, 2007). Although the dangers of lead poisoning are hidden and unobservable, Mattel should take the responsibility instead of doing nothing to prevent the dangers . This violates the ethical value of responsibility because Mattel failed to recognize their special commitments to their customers. Honesty For honesty, Mattel failed to forthright in dealings with customers and stakeholders. Mattel promises that their priority is the safety of the children who play with their toys (URLwire, 2007). However, there were four recalls in six months in 2007, but Mattel did not draw a lesson. In 2010, Mattel toys had been recalled for five times. One of the products called Trikes and Tough Trikes toddler tricycles led to 10 serious injuries before the product was recalled. In order to meet their promise and ensure the safety of children, Mattel should check the quality of their products carefully before they are sold. In these cases, Mattel did not have an adequate quality control in the manufacturing process. Being the largest toy company in the world based on the revenue, Mattel should not recall the defected products only if the injuries happen. As a result, Mattel did not honor their promise to place children safety at the first place. This violates the ethical value of honesty according to AMA. Citizenship In terms of citizenship, Mattel failed to fulfill the economic, legal, philanthropic and societal responsibilities that serve stakeholders. Greenpeace evidenced that Barbie doll packaging come from Indonesian rainforests. Mattel did not protect the ecological environment in the execution of marketing campaigns. Mattel was using products from Asia Pulp and Paper (APP), a pulp and paper company notorious for destroying Indonesian rainforests, leading to the extinction of Sumatran Tiger (Greenpeace, 2011). The product of Mattel, Barbie, was wrapped up in rainforest destruction which destroys the ecological environment and pushes critically endangered wildlife towards extinction. Although Mattel adopted a new packaging policy after the blame from the public, they still did a lot of damages to the environment. According to ! 1 AMA, this practice is unethical because Mattel failed to fulfill the societal responsibility to serve the public and violates citizenship. Conclusion To sum up, consumers lose confident to Mattel`s products because of the mentioned unethical activities. As the world largest toy company, Mattel should not only focus on their sales, but also be more responsible for the environment. Although it is impossible to guarantee zero defected products, Mattel should pay more afford on the quality control to make sure the safety of children. In other words, Mattel should balance the profitability and ethic to achieve her international position. !

Sample 2 ââ¬â Middle Score Corporationsââ¬â¢ marketing activities are important information channels for consumers to evaluate the products. Companies that utilize marketing activities to mislead consumers are regarded as unethical by the American Marketing Association. By examining iPhone 4ââ¬â¢s marketing strategies, Apple Inc. has been found to violate several ethical standards. ! Apple Inc. is a corporation that designs personal computers and computer software (Apple 2010). In recent years, the company has launched the iPhone series that instantly captivated the consumers (Dalrymple 2010). In contrast, the new iPhone 4 is not positively received by market consumers due to Appleââ¬â¢s unethical marketing strategies. These unethical marketing activities have generated controversies amongst market consumers whether the new gadget should be preferred over other smart phones. ! An apparent violation of the AMAââ¬â¢s statement of ethics is honesty. It is best demonstrated by the promotion of iPhone 4. The newly launched iPhone 4 have been reported by their users with a problem in reception quality. iPhone 4 has its antenna exposed on the outer rim of the phone which makes it more susceptible to interference. The report by Burrows and Guglielmo (2010) has documented Steve Jobs, the CEO of Apple, is well aware of the flaw in the design. However, official recognition of the problem only came after significant users have reported iPhone 4ââ¬â¢s call quality issue. In this manner, Apple has deceived market consumers into buying iPhone 4. ! Another ethical value that has been undermined by Apple is transparency. The underlying principle of transparency is to take responsible actions in regards to product risks that could affect customersââ¬â¢ evaluation of the product (AMA 2010). Although German and Ogg (2010) state the use of a free bumper case is able to eliminate the call quality issue, Appleââ¬â¢s responses to the crisis is unacceptable. It had tried to minimize its responsibilities in this incident by explicitly saying that other brands also have the antenna issue (Michaluk 2010). It had told customers to hold the iPhone differently in order to avoid the signal drop (Rothman 2010). The denial of responsibilities cannot demonstrate the company to have satisfied transparency in its marketing activities. ! Lastly, Apple has breached citizenship in accordance with the AMA ethical standard. A stress made in citizenship is to ââ¬Å"ensure that trade is fair for all participants, including producers in developing countriesâ⬠(AMA 2010). Recent incidents in the Foxconnââ¬â¢s factories have exposed Appleââ¬â¢s inability to uphold fairness while dealing with its manufacturer. Seventeen suicides have been attempted by Foxconn workers this year which raise suspicions about the working conditions inside the factories (Tam 2010). Although Foxconn is responsible for the harsh working conditions inside the factories, Apple has aided in the exploitation of labours in China by loosely overseeing its producer. In conclusion, Apple has seriously infringed several ethical standards that are set forth by the American Marketing Association. The company has violated the honesty principle by hiding the flaw in the antenna design and denies the mistake made by the engineering team. It has failed to uphold transparency by denial of responsibilities. Apple has breached citizenship by allowing Foxconnââ¬â¢s exploitation of labours in China. ! The overall failure to defend the marketing ethics has left several black spots on the companyââ¬â¢s profile. Apple will need to amend the damages done to its reputation in order to regain consumersââ¬â¢ faith. It should admit the mistakes made in the designing stage and take up the responsibilities by recalling the products for reconfigurations. The company should also exert tighter control over its supply chain to ensure fairness is ! 3 met. Only with such reparations can Apple restore its reputation in the subsequent products sales.
