History response 10 - Assignment Example The sudden halt of opium trade greatly affected the British since they were the main exporters and therefore the new rules meant that they would no longer conduct any opium trade with the Chinese citizens who were their main clients (Gibson). It is because of this that the Britons took up their weapons and headed for china in one of the most controversial war that has ever happened, â€Å"the opium war† (Gibson). The war resulted to massive loss of lives all in the name of free trade between China and Britain. Trade between China and Britain resulted large acquisition of wealth, this is because whereas the British obtained their wealth from the selling of opium to the Chinese, Conversely, the Chinese also benefited a lot from the trade since they also took this position to sell their tea to the Britons who were their major clients as well (Gibson). The British were real lovers of the Chinese tea to the extent that by the 18th century they would import about six million pounds of tea on an annual basis. The opium that was being exported to China was mostly used in the manufacture of drugs but the reason why the Chinese government suddenly decided to declare the trade illegal was the fact that the drug was being mixed with tobacco then smoked for more pleasure which later resulted to drug abuse and opium addiction(Gibson). Although the opium war caused massive loss of lives, but finally it resulted to development of a much greater China- Britain relations both in terms of trade and economic boost. Trade between the two nations received a boost after the construction of five ports in a move to promote foreign trade

Primate Evolution Essay Example for Free

Primate Evolution Essay The theory of evolution began when man first noted his distinct similarity to apes. The possibility of a common ancester with the modern apes had been discussed since the mid 1800’s, but it wasn’t until Charles Darwin published his book, On the Origin of Species in 1859, that the idea was considered legitimate. Since that time, fossil records have helped us to deliniate and define our evolutionary history and to describe the many human-like species that have lived on the earth over the last 8 million years. Charles Darwin studied a population of finches that had been isolated on the Galapogos Islands, and described the theory of natural selection, whereby over time, each finch had changed in ways that made it more successful in a particular niche. He observed fourteen different species of finches, all who were very similar, except for the size and shapes of their beaks. He noted how each type of beak was shaped very specifically for the type of food the bird ate and explained that the changes were due to the natural selection of the characteristics in a species that made it more successful at obtaining food and at reproducing. If a finch with a slightly longer beak was more efficient at eating termites from holes in trees, he would survive longer and reproduce more than his short beaked counterparts who ate termites. His offspring that inherited his slightly longer beak would also survive longer and reproduce more. Over time, the longer beaked finches would be more prolific than the shorter beaked version within that particular niche and the adaptation would flourish while the shorter beaked finches would die out. Eventually, speciation occured (the development into reproductively separate species), as the termite eaters with longer beaks became more distinctly separate within their environment and became reproductively isolated. This gradual change of a segment of a population into reproductively different species, in response to an environmental pressure (competition) for survival factors is called adaptive radiation. Although Darwin mentioned nothing about human evolution in his first book, his science minded peers were able to understand how his theory applied to humans. Initially there was much debate by the general population over the idea that humans could have evolved from the same lineage as an ape, but by 1870s, the scientific community had already come to the general conclusion that a fossil record would be found in Africa, where our great ape relatives were found. In the 1920’s, as predicted, Raymond Dart found bones from Australopithecus africanus, a hominid who lived between 2-3 million years ago in the Pliocene Era. They were discovered in a cave in Africa. From the skeletal structure he was able to determine that the specimen was bipedal; a defining trait of humans, and the size of its braincase was between that of modern humans and apes. Since that time, paleoanthropologists have been able to trace the evolutionary history of the primates including hominids, for some 85 million years and can determine many facts about their lifestyle through the study of fossils and other artifacts (O’Neal, 2006). There is not a complete record, and although paleoanthropologists have presented us with many pieces of the puzzle, we do not know exactly how man evolved into the species we are today. Some researchers have speculated that many of our developed traits were due to adaptations for an aboreal life. The premise of this idea is that as angiosperms became prevailant, an overlapping canopy developed that allowed cross movement from tree to tree. The canopy was a niche that had little competition and provided advantages for primates. Over time and through natural selection, primates took to the trees. They developed opposable thumbs and short finger nailed, grasping hands for holding onto branches, binocular vision for depth perception, and more complex brains to be able to better deal with balance and complex navigation (Simons, 1992). The difficulty with this idea is determining why, since there are other aboreal animals without these characteristics, primates developed them. There had to be some other factors that added the pressure for choice of these characteristics in primates. A primary characteristic of hominids is bipedalism. We likely developed from a chimpanzee-like, knuckle walking ancestor. The reason for the change from using all four limbs for locomotion to standing upright, on two limbs is unknown. There are several theories that focus on environmental conditions as being the motivating factor. One such theory is called the Savannah Hypothesis which proposes that due to drier conditions, the African forests thinned and disapeared. Bipedalism developed both as an adaptation to facilitate movement across the grasslands and as a way to give early hominids use of their hands for food cultivation and tool use since they were no longer needed for locomotion (Simons, 1992). The pressures that fuel evolutionary trends are those that are required for the species improved survival. We immediately think of food and shelter, but perhaps the most critical in insuring the continuation of a species is reproductive strategy. Primate reproductive strategies today include those that are monogmous (one male and one female), those that are polygynous (one male and multiple females), those that are polandrous (one female, multiple males), and those that are promiscuous (multiple males, multiple females). Eighty percent of primates practice polygyny, eighteen percent practice monogomy, with polandry seen only in some of the Callitrichids, the marmosets and tamarins, and promiscuity seen in chimps. The evolution of polygyny can be easily rationalized. In polygynous strategies, the egg has a high energy cost and the female puts her energy into childcare. Males may help with childcare as well, but females have a long period of gestation and then a period of lactation, so childcare is their primary focus. Females must focus also on food, not only for themselves, but for their offspring, whether directly or as an energy source for lactation. Therefore, female primates will naturally search for food sources. It is advantageous for females to congregate for childcare, for shared food sources and for safety. Reproductive success for a female primate is through the focused care of each individual offspring. Males do not have the same enforced biological costs throughout the reproductive process. Sperm are easily produced in large quantities at a low energy cost. Reproductive success for males is through the number off offspring he can produce. Under these circumstances, polygyny is the most efficient reproductive strategy for species survival (O’Neal, 2006). Mongomous primates have a different environment. Monogomy is driven by the spacial arrangements of females or when the male’s role in childcare is critical. When females do not gather, it is logistically not feasible for the male to obtain additional mates. Gibbon females will not tolerate another female in her claimed territory. The males might have the tendancy toward polygyny, but the females won’t allow it. Monogomy in tamarins is necessary because of the relative size of the offspring to parent size. The young, although still dependent on parental care, quickly grow to near adult size. It is nearly impossible for a single female to raise her offspring alone. Although reproductive strategy is varied among primates, each species’ tendancy is based on the evolutionary pressure for their survival and success. Recent fossil discoveries have been able to describe an evolutionary history that dates back as far as 4. million years ago to the Autraliopitecines. An almost complete skeleton was found in 1974 in Hadar, Ethiopia and adopted the name Lucy. This was the first human –like homonid. Lucy was bi pedal and had a large brain for her body size of 48 inches. Since that time, other fossils of Australopitecines have been uncovered, but Lucy remains the most complete, and is the standard for the species (Primate Info Net, 2008). Homo habilis is thought to have descended directly from a species of Australopithecine hominid and lived from approximately 2. 2 to 1. million years ago. Fossils found in Tanzania in 1962 by Louis and Mary Leakey show that Homo habilis was short and had long arms, like the Australipithecines, but had a decrease in facial protrusion, giving it a more human-like appearance. They used rudimentary tools in their hunting and gathering (Primate Info Net, 2008). Homo erectus had a larger brain case than Homo habilis and stood slightly more erect. They also had more sophisticated tools that were able to cut and slice. They had discovered the use of fire and were the first actual hunter-gatherer society. They lived approximately 2. 2 to 1. 1 million years ago and were the first to leave Africa and travel throughout the Great Rift Valley (Primate Info Net, 2008). . Homo sapiens archaic or Neanderthal Man inhabited Europe and parts of Asia approximately 1. 2 million years ago. They were a fairly sophisticated society. They buried their dead, had fire, ate meat and had modern tools like hand axes and knives. They were adapted to a colder climate with short, robust statures and large noses. Their brain capacity was greater than modern humans and they had language. There were probably only about 10,000 Neanderthals and they slowly disappeared as modern man, Homo sapiens sapiens began to appear 200,000 years ago (Primate Info Net, 2008). . Throughout man’s evolutionary history there has been a trend toward greater intelligence, mobility and refined physical and mental control. We are evolving each day towards a better version of ourselves. Are we the final model? Or will we eventually be replaced by a more efficient, successful hominid? In all likelihood, we will.

Schottky Diode Lab Report

Schottky Diode Lab Report INTRODUCTION A Schottky diode is the common name for a metal-semiconductor junction, it is the work function between the semiconductor and metal that determines whether the junction is ohmic or rectifying [1]. This lab will focus on the fabrication of a Schottky diode and the characteristics they possess. In principle, Schottky diodes are rectifying as the current can only flow one way. They can also handle high frequencies and have lower power loss which makes them ideal for many applications [2]. These include being extensively used in power electronics, general purpose rectifiers and due to its non-linear I-V curves, it is able to be used as a varistor which in turn can be used for voltage suppression [2]. Also there is a low capacitance of the device which makes it more ideal than alternative diodes. OVERVIEW OF THEORY An Ohmic contact is needed on the bottom part of the sample as without this, any measurements taken would create a very high resistance as the semiconductor and the metal probe used to measure would create two diodes facing each other, therefore no current could flow. This is overcome by diffusing indium and germanium onto the semiconductor wafer. Gold is also used to prevent any oxidisation on the sample. The wafer is firstly placed into the tube furnace with the gold, indium and germanium on it then heated at 420 °C for 90 seconds. This is to enable quantum tunnelling so there is little resistance and only the semiconductor and top metal are measured. Figure 1 shows the energy band diagram of a metal-semiconductor junction, which is rectifying as the work function of semiconductor is higher than that of the metal. Figure two is the Schottky diode characteristics and when compared to figure 3, the PN diode characteristics, it shows that the turn on point is lower in the Schottky diode, which means less power is needed to operate, however there is a higher leakage current in reverse bias. DEVICE FABRICATION When working with such easily influenced devices, safety must be upheld at every milestone. This is first enforced by the dress code that is required in the laboratory. Each person must wear an overcoat, safety glasses, gloves, overshoes and a hair net. Due to e ven the smallest particles being able to affect each sample, the dress code is necessary to ensure that very little dust gets into the clean room. Also, there are many different chemicals in the room therefore more precautions are needed when working with them. All guidelines set out by the Control of Substances Hazardous to Health (COSHH) regulations must be vigorously followed. Using these guidelines, all chemicals must be used inside a fume cupboard as any spillages will be contained and the fumes can be collected. There are also hot plates and other specialised equipment that should be handled with care to ensure no damage comes to either the user or the machine itself. The cleanroom is comprised of 3 different areas. The first is where the entrants of the cleanroom put the safety equipment on, the second is the main laboratory area and the final is the yellow room. Each room is connected to the next with interlocking doors that only open when all others are closed.   This is because each has a different pressure level due to the need of having to keep as little dust in the main room to stop the contamination of samples. The high pressure level in the main room help to filter out any unwanted particles in the room. The air flow is also monitored to ensure that if there is a drop in pressure, the right actions can be taken to rectify any issues. The yellow room has special lighting due to the sensitivity of the devices that will be later described, however the main difference is that both red and blue colours have been taken out as the devices are easily affected by UV lights. The clean room being used for this experiment is classified as Class 6, this refers to the particle size compared to the maximum particle density. Once all safety aspects have been covered, the process to create the device can begin. The first step is cleaving. This is where the wafer is cut into small sample sizes, usually 3x3mm, as the wafer is very expensive and only a small amounted is needed to complete the experiment. A special machine can be used to perform this however it is also achievable by hand. When the sample has been cut to the necessary size, it is essential that a three stage solvent cleaning method is used. This is to ensure that there is little to no dust on the sample. To complete the three stages, the sample must first be placed into a beaker of N-Butyl Acetate (NBA) that has been heated on a hotplate. Once it has been in the beaker for a short amount of time it must be removed and then cleaned with a cotton swab that has also been dipped in the NBA. This is done by rolling the swab forward whilst pulling back so that as many particles as possible are collected. The sample is the turned 90 ° and swabbed again to collect any particles that may have been missed. This process is again completed but with the sample being dipped in Acetone and then Isopropyl Alcohol to complete the three stage cleaning. After this has happened, the sample is then dried with Nitrogen gas. Due to the small size of the sample, it is much easier to handle on a larger material, such as a glass slide. This is done by heating the slide on a hot plate then melting wax onto it then placing the sample on that. This is then left to cool and will now be ready for the next stage. The next stage is photolithography. This is required to put a pattern onto the sample so that testing of the device can happen and is exclusively completed in the yellow room. As mentioned earlier, the stages throughout this part will mean that the sample will be affected by UV lights so it is necessary to complete this in the designated room. Firstly, the sample is placed on a hot plate for one minute. Then it is placed onto the spinner and spun at 4000rpm for 30 seconds and dried with nitrogen gas. Now a few drops of photoresist are added, this is the solution our sample will be printed with. Again the sample is placed in the spinner 30 seconds and then soft baked on a hot plate for exactly 1 minute. If the sample is baked for too short, the sample will stick to the machine used in the next part and if baked for too long the sample may become damaged. Once the sample is completely dry, it is placed into the mask aligner. Each corner is lined up using the microscope and the camera s o that a complete pattern is across the sample. Once completed, the machine is set for 6 seconds and exposes the sample to UV light, the time needed varies with different materials. The sample is then washed in a beaker of developer solution for exactly one minute as again if the time is not strictly adhered to, it can have adverse effects on the sample. Finally it is washed in deionised water and dried with nitrogen gas. Now the sample has the same pattern which was imprinted from the mask aligner as the photoresist has been taken away from the parts that are needed. Now metallisation must happen as the sample needs a metal layer placed onto it. This is completed by placing the sample in a vacuum chamber and placing a small amount of aluminium inside a tungsten coil. Tungsten is used as the process involves heating the chamber to a point where the aluminium will evaporate but the other materials will not. As the chamber heats, the aluminium creates a thin layer across all of the inside of the chamber, this layer is approximately 0.2ÃŽ ¼m which can be calculated by knowing the amount of aluminium used. As the chamber is a vacuum, there will be no chance of an oxide layer being created which would ruin the sample. Using the vacuum also means that less pressure is needed and that a lower temperature can be used. Due to the evaporation covering the entire surface of the sample, the Lift-off process is needed to remove any parts of the metal that is not needed. The photoresist has protected some parts of the semiconductor from the metal and this needs to be removed to leave the parts where there is a direct contact between the metal and semiconductor. This is done by placing the sample in a beaker of acetone and syringing the sample until the photoresist, and the metal on it, is removed. This process is usually quite quick but can take anywhere up to 20 minutes. The final stage before the sample is ready for experimental observation is to remove the sample from the glass slide. This is completed by heating the sample on a hot plate until the wax has melted. Once this happens the sample is then cleaned with the same three stage solvent cleaning method earlier describe to remove any remaining wax. Finally it should be dried with nitrogen gas, with care taken as the sample could be blown away due to it not being on the glass slide. Once the all stages have been completed the sample is ready for analysis at the probe station. DEVICE CHARACTERISATION Now the slide is ready, the first test can commence. The sample is placed in the probe station and a Source measurement unit (SMU) is connected to the probe station and a computer so the results can be recorded. As the SMU acts as both the source and meter, this is connected to one probe whilst the base is connected to the other. Now the probe is carefully aligned onto one of the small circles that has been created on the sample, with great care being taken due to the sample only having a very thin layer which is easily penetrable. Next, a voltage sweep is created from -3V to 3V with a low current limit so ensure the device is not broken. Once the data has been recorded the probe is moved onto a different circle and the process is repeated. The behaviour of the Schottky diode can be modelled by the following equation: If the gradient of the voltage versus Log(J) is taken, the equation can be rearranged to find n. n is the factor that is used to determine the non-ideality of the diode. The values for the current density and n can be found in table 1. The next experiment is to measure Capacitance verses Voltage. The measurements will be taken in a similar way to the IV measurements however, a LCR meter will be used instead. This is due to the LCR being able to measure capacitance and phase angle. For these measurements, the sweep will start at 0 and be reduced until the phase angle is roughly 75 °. This is due to the need of being in reverse bias. The following formula can be used to find the dopant density of the semiconductor. The dopant density of the sample was found to be ***. The voltage barrier of each diode can be found by taking the gradient of the graphs. DISCUSSION AND CONCLUSIONS Reviewing the IV graphs it is clear that as the current increases, the linearity of the current density starts to become unstable. This can be explained due to the possibility of defects in the sample. In most industry practices, technicians are not present during the manufacturing fabrication stage and is solely completed by machines. Even though great care has been taken to ensure that the samples used in this exercise have been unaffected by unwanted particles, there is clearly still evidence of impurities throughout the sample. When the data from the CV graphs is reviewed, the observation that as the diameter of each diode increases, the barriers height decreases can be made. Having a higher barrier height is important as this will create a rectifying contact which is beneficial as it only lets the current flow one way. Therefore the conclusion can be made that having diodes with lower diameters have more advantages when creating Schottky diodes. This lab has demonstrated how a Schottky diode has been made and what the different characterises are. Great care has been taken to ensure little impurities affect the sample however there is still room for improvement and shows the essential need to uphold the safety requirements. Due to the low power needed and the fast switching abilities Schottky diodes are able to be used much more universally than standard PN diodes.

Business Ethics Essay

1.Introduction Precisely define the concept of â€Å"ethics† is quite difficult. In a general sense ethics – a set of moral principles and values that govern the behavior of a person or group of people and determining the positive and negative assessments of their thoughts and actions. Ethics associated with inner values, and they in its turn are part of the corporate culture and influence on decision making, determine their social validity within the environment. Ethical problem arises when the actions of an individual or organization may harm or conversely benefit others. Since ethics are unwritten rules, the issue of assessing an action often has irreconcilable differences. The so-called ethical dilemma arises in a situation where all the alternative solutions or courses of action because of its potentially negative moral consequences are undesirable, it is difficult to distinguish good from bad, right from wrong. Person who assumes responsibility for the organization of emerging ethical issues, often referred to as an agent of morality. This assignment examines the various approaches to the ethical issues, the study of which allows management to develop criteria for their analysis and solutions. 2.1 The Four approaches to make ethical decision Most ethical dilemmas is a conflict between the whole thing and its parts: the organization and the individual, the community and the organization. For example, should the company be subject to mandatory testing of their employees in the use of drugs and alcohol, which can benefit from it, but it restricts the freedom of action of individuals? Is it right to export goods that do not meet national quality standards in other countries with less stringent requirements? Sometimes ethically complex solutions involve a conflict between the two groups. For example, what is more important: the pollution caused by wastewater businesses or jobs that it creates, as the largest employer? Faced with the problems of an ethical choice, managers tend to be based on a normative point of view, that are certain norms and values, in accordance with which decisions are made. In normative ethics identify several approaches to the description of the system of values and hence the adoption of ethically diff icult decisions, which can be used in the practice of management: THE UTILITARIAN APPROACH, THE RIGHTS APPROACH, THE FAIRNESS OR JUSTICE APPROACHES AND THE VIRTUE APPROACH. 2.2 The Utilitarian Approach Basic principles developed in the XIX century by philosophers Jeremy Bentham and John Stuart Mill’s utilitarian approach states that appropriate behavior morality brings the greatest benefit to the greatest number of people. An individual decision-maker should review the impact of each option on all of its stakeholders, and to lay the one that brings satisfaction to the greatest number of people. In essence, it is about finding the best solution. As the complete calculations can be quite complex, allowed simplified conditions. For example, the calculation of costs and benefits in monetary terms can be used a simple economic criterion. In addition, while deciding rightly consider the situation only directly affected their sides. Utilitarian ethics justifies the introduction of a ban on the use of alcohol and smoking in the workplace, and in some cases at the end of work, as this behavior has a negative impact on the collective organization. Similarly, many companies monitor Internet use explains the need to maintain a healthy and productive environment. If employees are browsing pornographic websites, participate in racist forums or whole day browse on the virtual shopping, eventually suffers organization. Anyone who uses a utilitarian approach, assessing the impact of specific actions on the people who are directly involved in this process, while trying to produce the greatest good for the greatest number of people. Utilitarian approach focuses on the actions themselves, not the motives behind these actions. Potentially positive results of actions are weighed against the potential negative results. If the former outweigh the latter, manager, guided by a utilitarian approach is likely to begin to consider the action. The fact that some people, these actions could adversely affect recognized the inevitable and acceptable. 2.3 The Virtue Approach The virtue approach assumes that the moral and human actions are acceptable that benefits in the long term. The main driving force is self-control, and all the external forces that limit it should be stopped. Each person chooses for himself the most profitable in the long-term solution, based on which it judges the quality of their actions. One of the features of this approach is that it allows of the individual, aimed at the acquisition of personal short-term gain, in general, do not meet social norms. Precisely because individualism can be easily interpreted as a desire for purely personal purposes, it is not very popular in today’s highly organized communities focused on group goals. The approach most closely approximates to the area of free choice. 2.4 The Rights Approach The rights approach holds that man was originally endowed with fundamental rights and liberties, which cannot be violated or limited by decisions of other people. This means that the ethically correct to the solution that best respects the rights of those affected. It is assumed that the ethically correct decision should not violate these fundamental rights. Thus, the decision to listen to conversations of employees violates their right to privacy. Sexual harassment is unethical, as contrary to the right to freedom of conscience. The right to free speech justifies the actions of informants reported to management of the organization or the authorities about illegal or inappropriate actions of officers. Those who adhere to the rights approach, assess whether the decisions and actions of the basic civil and group rights and privileges. Some of these rights and privileges are listed in documents such as the Bill of Rights (the first 10 amendments to the Constitution of the United States) and the United Nations Declaration on Human Rights. The rights approach takes into account human rights such as the right to life and personal security, privacy, freedom of conscience, freedom of speech and private property. 2.5 The Fairness or Justice Approaches The conception of justice claims that ethically correct decision should be based on principles of equality, fairness and impartiality. In terms of management, there are three types of justice. Distributive justice requires that the ratio of managers to subordinates based on objective criteria. Thus, if the decision relates to such individuals to each other, it should equally apply to that and the other. Therefore, if a man and a woman do the same work assignment, they get about equal pay. However, if between the employees there are significant differences (for example in terms of skills or responsibilities), the ratio of management to them varies according to the skill level or display a sense of responsibility. But the attitude of the manager to subordinates must be clearly linked to the goals and objectives of organizations, not from other sources. Procedural fairness requires fair administration of subordinates. The rules should be clear, concise, and unbiased constantly enforced. Compensatory justice requires responsible party to compensate the damage caused to people. Moreover, people should not be held responsible for events that are beyond their control. The concept of fairness is closest to the legislation, as it is based on rules and regulations. This theory does not require complex calculations, as in the utilitarian approach, and does not serve its personal interests, which is possible in a virtue approach. It requires managers to determine for itself the characteristics of attributes, according to which evaluate the actions of workers. The conception of justice supports attempt to correct mistakes of the past, as well as fair play within the rules. In accordance with it the basis for a different pay or promotion can act reasons related solely to perform the job tasks. Most of the administration of human resources rules and laws are based on the concept of justice. Manager, who uses the approach of social justice, judges of how its actions fair and impartial in the distribution of awards and values among individuals in groups. These ideas arise from the two principles known as principles of freedom and differences. The principle of freedom holds that man has certain liberties that are compatible with the same freedoms enjoyed by other people. The principle differences argues that if there are doubts about the correctness of a decision, all the social and economic injustice, thus eliminating the need to be able to more fairly distribute goods and services. 3.Conclusion 4.Recommendation Most people, who are in business, hold a utilitarian point of view on the issue of business ethics. Arguing it actions to maximize profits, the CEO can always say that it thus seeks to ensure the maximum benefit for the majority of stakeholders. As a result of extreme volatility environment management personnel must reject this approach. A characteristic feature of utilitarianism is â€Å"impairment† interests of the individual and minority interests of the majority, and new trends in the field of human rights and social justice require that managers need ethical standards based on diametrically opposed principles. This is a complex task of modern management as well as management decisions should be made taking into account criteria such as human rights, social justice and the standards of the local community. This will increase the degree of ambiguity of administrative decisions. As a result, managers are increasingly faced with problems of moral and ethical character. Business ethics Essay The lecture of Father Roa last February 16 is an introduction to Business Ethics subject. The discussion included businessman’s myth about business ethics, the relationship of ethics and business, moral reasoning in business, the theory of profit motive, and business ethics definition. These given me deeper understanding of the subject â€Å"Business Ethics and Social Responsibility†. Some of businessman’s myth about business ethics includes: Ethics is a personal affair and not a public debatable matter; Ethics and business do not mix; This in business is relative; Good business means good ethics; and Business is war. These myths will remain a myth. The relationship of ethics and business which cannot be separated from one another. Ethics is an unwritten law, written in the heart of men. Business is an integral part of the human society with activities must also be examine from the moral perspective. In business, what is legal may not be necessary be moral. Today, the trend is to train managers to maximize profits and to quantify the operation of business. With moral reasoning in business, ethical issues and problems affecting the organization must be solved by the manager. Always judge the action based on an ethical principle. A good moral standard will be necessary have a good for me and for everyone, must be objective and not subjective, and when violated bring about feelings of guilt, share and remorse of conscience. The assumption of profit-motive is that it is an ethical issue in business and operates within the framework of freedom and structure of the business itself. There are two sides of profit-motive, good and bad. The good side is that profit-motive motivates people to do something meaningful, promotes ingenuity and cleverness in running a business, makes people productive and generates potential capital for business. If here is a good side, bad side also exist that includes promoting rivalry among competition, focus on only making money, and promote self interest. There are ethical considerations of profit-motive in business. The earning profit is a good and valid activity in business however, making excessive profit totally wrong. The teachings of the Catholic Church do not totally condemn profit as part of the business activity. In the end, business ethics was defined as study of what is right and wrong human behavior and conduct in business. This is a study of perception of people about morality, moral norms, moral rules and institution in business.

Immediately I’d hand him my painfully heavy bag

When the bell rang at school I always waited anxiously to hear him. He’d call my name and when I turned around I knew exactly how he’d look. I’d still stare and smile back at his crinkly smiling eyes.   He’d always have his sunglasses on top of his bald head.Immediately I’d hand him my painfully heavy bag. At that moment all my homework troubles and test woes were over. He’d ask me the usual about school and friends. Although he knew I was shy around other people and often bullied around, he’d still ask, â€Å"How many kids did you beat today at recess?† The irony of it always made me laugh.While he drove me home he always chatted like a chirpy bird. He’d make his usual stop everyday. I knew what he’d say before leaving the car but I always looked forward to it. He’d say conspicuously, â€Å"Let me say a quick hello to my friend†. I’d   know exactly why he stopped but I’d play innoce nt.The stop meant he was getting candies from the store. He’d return back with chocolates and colored candies smiling, and say, â€Å"My friend sent these for you†. I can’t ever recall him not smiling. With the greed of a 6 year old I’d peer into the big bag and immediately gobble the loot before the school bus even reached home.I remember this particular day spent with him. While I was sitting in the backseat of the school bus and gloating over my treasure and with my mouth still full of chocolates I exclaimed, â€Å"You’re the best uncle ever; you buy the best things even when I never ask you for them†. He looked back at me from the rearview mirror and smiled.But, I remember seeing something strange and wistful in his eyes. I couldn’t understand it then but he said, â€Å"One day when you’re all grown up and going to university, I will pass you by on the street and I will call out to you but you wont recognize your Uncle Rob †¦I will ask you don’t you remember me? But no mater how hard you try, you won’t be able to remember me†.I was mad at Uncle Rob that day. I was angry at his confidence in the future that he had never seen. I reasoned with him as much as a six year old can. He stood firm. I explained to him again and again that I see him first thing in the morning when he drops me to school and last thing before he drops me back home. This will have to continue till I’m sixty years old and don’t need to go to school. He laughed sadly and shook his head in disagreement.The school year ended and Uncle Rob stopped picking and dropping me from school. I remember laughing, arguing and played games with him. When I moved to another state at the end of the year I made a mental note to myself to remember him.I put a flag to his memory and engraved his image in the deep recesses of my mind. I promised to never forget him. I’m almost 24 now and his memory is still flawless in my mind. But I wonder, if I’m walking on the street and come across a man with those crinkly smiling eyes and I call out his name, will he remember me?
