History (Lindeberg, David C. 2007. The Beginnings of Western Science. 2nd Ed. University of Chicago Press - Essay Example (Ancient Greek Medicine, 2002) Romans had a strong relationship with Greece and the Greek medicines, especially the Hippocratic, were popular among Romans as well Hippocrates, the ancient Greek physician is considered as the father of medicine and still all the medical students in the world take the Hippocratic Oath as a matter of respect to this greatest contributor to the medical field. Hippocrates is believed to be the first one who rejected the idea of the involvement of supernatural as the cause of diseases. He was the one who was able to separate the medicine from religion. As per the ancient beliefs, diseases were considered as the curses of God. Hippocrates has proved that diseases were happened due to reasons other than the one taught by the religion and he considered medicine as a science rather than religion. The Hippocratic writings introduced patient confidentiality, a practice which is still in use today. â€Å"Hippocrates recommended that physicians record their findings and their medicinal methods, so that these records may be passed down and employed by other physicians. Other Hippocratic writings associated personality traits with the relative abundance of the four humours in the body: phlegm, yellow bile, black bile, and blood, and was a major influence on Galen and later on medieval medicine†(Hippocrates) ANATOMY is the study, classification, and description of structures and organs of the body.

Organisational Citizenship Behaviour and Counterproductive Work Behaviour Essay Example for Free

Organisational Citizenship Behaviour and Counterproductive Work Behaviour Essay Organisational behaviour is the study of human behaviour in the workplace, the interaction between people and the organisation, and organisation itself (Dubrin 2002, p. 2). In most of the organisational behaviour literature review, the following five types of behaviours are often highlighted- task performance, organisational citizenship, counterproductive work behaviours, joining and staying with the organisation and work attendance (McShane, Olekalns Travaglione, 2009). These individual-level dependent variables are present in most OB research which has a significant impact on the effectiveness of organisations. In my following essay, I will be highlighting on two of the above factors-mainly Organisational Citizenship Behaviour (OCB) and Counterproductive Work Behaviour (CWB). I will be discussing on how various authors agree that different personalities and positive affectivity levels contributes to the emergence of OCB and that how different authors view the stand of considering all OCB as voluntary acts based on own accord. In addition, I will also be discussing the issue in which a consensus has been reached by most authors that job dissatisfaction is one contributing factor of CWB and that CWB, being defined as harmful in nature, has been challenged by some authors to be a justifiable act. OCB Organisational Citizenship Behaviour (OCB) has been defined as individual behavior that is discretionary, not directly or explicitly recognized by the formal reward system, and that in the aggregate promotes the effective functioning of the organization (Organ, cited in Vigoda-Gadot, 2006, p. 3) or as individual behavior that promotes the goals of the organization by contributing to its social and psychological environment (Organ; Rotundo Sackett, cited in Vigoda-Gadot, 2006, p. 3). Personality and Positive Affectivity Personality refers to the enduring, inner characteristics of individuals that organise their behaviour (Derlega et al, cited in Rothmann Cooper, 2008, p. 24) and personality traits predict what a person will do as opposed to what he or she can do (Rothmann Cooper 2008, p. 24). As such, it is agreed that citizenship performance is well predicted by personality variables (Penner, Allen, Motowidlo, 2001; Hurtz Donovan, cited in Barrick Ryan 2003). It is also stated that differences in citizenship performance by the employees are clearly tied to the differences in their personalities and attitudes (Landy Conte 2004) and feelings about their work, also known as affects (Lee Allen 2002). I came across this survey done by (Bierhoff, Klein Kramp, ed. Murphy 1996) in which ‘first aiders’ who rushed to the aid of the accident victims almost immediately scored lower on a measure of egocentrism- the absorption with one self’s lives and family. They also scored higher on a measure of empathy in which they expressed a greater level of concern for others (ed. Murphy 1996). From the above results, I feel that various personality factors do influence the tendency of one to render help to others thereby performing citizenship performance which benefits the organisation as a whole. In addition to the above, I have learnt that the higher the level of positive affect, the higher the level of willingness to help is in individuals (ed. Murphy 1996). Besides the helping behaviour, I have also learnt that maintaining a positive mood in the course of our work may also inadvertently lead us to performing extra role behaviours (e.g.: protecting the organisation and developing oneself in terms of upgrading one’s skills to the benefit of the organisation) (George and Brief, cited in Lee Allen, 2002). To my surprise, I found that positive affect is not just influenced on a personal level but also due to external environmental factors. These include the differences in shades of lightings at our workplaces (Baron et al, cited in ed. Murphy 1996) and even presence of pleasant smelling artificial fragrances in our workplaces (Baron Bronfen 1994, cited in ed. Murphy 1996). Performed based on free will? Most of the recent studies and researches on OCB have pointed out that it is based on voluntary helping behaviours. However, (Vigoda-Gadot E 2006, p. 1 ) pointed out on focusing on the exploitative and abusive tendency of supervisors and managements to impose so-called ‘‘voluntary’’ or ‘‘extra-role† activities via compulsory mechanisms in the workplace, thereby refuting the conventional definition of OCB being performed based on ‘good will’ and free choice. In fact, some of these behaviours categorised under OCB may well be categorised under Compulsory Citizenship Behavior (CCB) (Vigoda-Gadot 2006, p. 1). By reviewing the Expectancy Theory (Griffin Ebert 2005, p. 246) in which people are motivated to work towards rewards that they want and that they believe they have a reasonable chance or expectancy of obtaining it in mind, I have actually agreed with the view that there is much possibility that OCB can also arise from other motives, some of them less voluntary or less self-initiated. Among these motivations are the abusive and exploitative behavior of immediate supervisors and the pressure by management or peers to become involved in activities in which the employee would otherwise not involve himself (Tepper, cited in Vigoda-Gadot 2006, p. 3). CWB Counterproductive Work Behaviours (CWB) is defined as voluntary behaviours that have the potential to directly or indirectly harm the organisation (McShane, Olekalns Travaglione T, 2009, p. 18). Job Dissatisfaction Job dissatisfaction is defined as a set of unfavourable feelings and emotions with which employees view their work (Newstrom Davis 1997, p. 255). It seems that authors have a consensus on job dissatisfaction contributing to the emergence and high levels of CWB. It is stated that dissatisfied employees may engage in psychological withdrawal (e.g.: daydreaming during job), physical withdrawal (eg: unauthorized absence, early departures, extended breaks, work slowdowns) or even overt acts of aggression and retaliation for presumed wrong. There are many factors influencing job dissatisfaction which includes organisational factors like pay and promotion opportunities and the working condition itself. Group factors like the role of supervisor and co-workers; personal factors like needs and aspiration and how are these met, and how individuals views he instrumental benefits of the job also contributes to job dissatisfaction( Rothmann Cooper 2008, p. 24). Though I am in agreement that job dissatisfaction is a strong contributor to the performance of CWB, I feel that CWB may also be induced by other factors like accumulated work stress leading to the emergence of violence which is one form of CWB. Similarly, theft cases in the company, which is another form of CWB, may just be a personal justification of the employees due to a perception of lost equity in the course of their work (Newstrom Davis 1997). Justifiable Act Various authors held on to their individual stands regarding the topic on CWB. In most of my readings, authors agreed that CWB are actually harmful acts towards either individuals or towards the organisation itself. However, (Fox 2002) had presented a different point of view discussing the view that CWB may could well be a justifiable act which is clearly challenging the most conventional definition of CWB which is being negative in nature. (Fox 2002, p. 2) expanded the definition of CWB to include unintentional harm, as long as the act itself is volitional- an act which is motivated by other reasons to cause harm. Hence with this expanded definition, it raises the possibility of constructive CWB. In their article, they have considered on 3 categories of arguments which are moral issues, role conflicts and productivity arguments. I personally feel strongly for the argument on role conflicts. Many of the withdrawal behaviours may be seen as counterproductive in the perspective of managers or even organisations. However, these behaviours shown may be required to be fulfilled by the employees in the perspectives of their family and even the community. Putting in simpler terms, employees may be expected by the society to perform these behaviours so as to be able to strike a work-life balance. Hence, I feel that CWB should not be seen as just a negative behaviour which is purely deviant from an organisation’s objectives as I strongly feel for the presence of positive CWB. Key Findings In this modern age, to adapt and survive in a workplace, other than equipping oneself with the generic skill of problem solving, it is also vital to place great importance on understanding fellow colleagues as this will lead to self knowledge and self insight (Dubrin 2002, p. 4). By understanding what motivates others to perform OCB through the study of organisational behaviour, it will also in turn allow employees to gain an understanding on what motivates them to have similar behaviours. Inadvertently, this may bring them to a greater level of job satisfaction which also leads to greater organisational effectiveness as a whole. In addition, studying organisational behaviours enhances a professional or manager’s effectiveness relating to their interpersonal skills. Hence, if solid interpersonal skills are added on to one’s professional or managerial knowledge, it will certainly be a bonus towards an organisation’s overall service and productivity. Hence, information about organisational behaviours is vital to be known to the employees in organisations. Reflection If I were given a chance to assume the role of manager in an organisation, the notion of having OCB being induced by compulsion as mentioned earlier on will certainly be omitted by me as I feel that though it is an important goal of managers everywhere to make employees aware of the benefits of OCB and ideally, encourage it, it is far more important to conduct it through a legitimate way and not by other means such as abusive or exploitative activities. In this way, I believe conventional OCB will indeed be truly promoted as the employees will be serving and going the extra mile for the organisation in the most genuine way as I agree with the view that a person who engages in OCB might receive appreciation and recognition that induce positive moods and there will be a greater likelihood of repeating the OCB (Miles et al, cited in Zirgham 2009, p. 85) which will greatly benefit the organisation. A discrepancy often exists among managers and employees about the definition of certain work tasks being â€Å"in-role† or â€Å"extra-role†. Each behaviour may be different for different people as every employee in an organization perceives job requirements differently (e.g.: for service sectors), helping others may be a routine, but some may see it as beyond their job scope. By acknowledging this in the position of an employee, I will be able to anticipate this possible occurrence of conflict between managers and employees and thus, expand the boundaries for the definition of my job scope. In this way, I believe that my chances of managerial exploitation and workplace abuse by supervisors to perform compulsive OCB will be reduced to the minimum. Conclusion OCB is a stable behaviour emerging in workplaces and it will always act as a value adding criterion in one’s performance. However, it will only act as a value adding criterion only when it is performed through the free choice of employees and not by coercion means and negative external pressures. Thus, we have to be aware and alert so as to preserve the original positive results of OCB being performed, leading to a more successful and healthy establishment of an organisation. CWB is always seen as a conduct having an adverse relationship with OCB. However, as the saying goes- there are always two sides to the same coin; we should probably broaden our perspectives in our view towards CWB and accept the notion that CWB may not be necessary all detrimental in nature.

Ethical Issues Qualitative Research On Internet Communities Media Essay

Ethical Issues Qualitative Research On Internet Communities Media Essay Ethics are always considered in conducting social research. Ethic is a set of principles, moral duties and obligations that guides the conduct of people (American Correctional Health Services Association, 2010). For social research, ethical is to conform to the standards of conduct of a given profession or group (Babbie 2007, p62). Generally, there are four ethical principles should be concerned in conducting social research including no harm to participants, informed consent, voluntary participation, and privacy and confidential. Here, Qualitative research into internet communities has created new ethical issue of informed consent. Informed consent means that subjects must base their voluntary participation in research projects on a full understanding of the possible risks involved, (Babbie, p64). In fact, the research on internet communities has led to a violation of this principle. Internet communities such as discussion boards, mailing lists, chat rooms, or newsgroups, provide rich information about peoples opinion or daily experiences. It is useful for researchers to obtain relevant data, such as some patient self support communities sharing their personal experiences. Researchers can access to those communities for acquiring information and observation. However, it brings a problem that some internet communities members do not want to be the research subjects and being monitored. Researchers might be intruders and damage the communities. Here, members are not the voluntary participants. Then, informed co nsent here may not work. Besides, there is also harm to research subjects on the internet communities when researchers are interested in insight research. For example, some of the members on Breast Cancer Mailing List claim that they do not want to be observed. When researchers are gaining insight personal experience about the breast cancer patients, it can recall their negative memories which lead distress to them. And the second main ethical issue is that there is a risk of disclosing to the privacy and confidentiality of internet communities member. Privacy and confidential is about the researcher can identify a given persons responses but promises not to do so publicly (Babbie 2007, p65). Since internet contains many of powerful search engines such as Google, it can search anything a user wants. For example, when the authors search for the Dejanews archive to find comments of newsgroup participants responding to researchers requests, it can show many of related messages. Another issue on privacy and confidentiality is that there could be various pitfalls for researchers. Particularly researchers may unintentionally violate the privacy of some members due to the blur spaces of internet. For example, even if researchers remove any personal information about research subjects, they may also breach the participants confidentiality due to the power of search engines. Thus, privacy and confidential on internet community is difficult to achieved. Words: 482 The authors distinguish three different types of research into internet communities. Summarise them in your own words. (400 words) Generally, the three types of research methods may include the passive analysis, active analysis, and identifying themselves as such and gathering information in the form of using internet. First, the first type is the passive analysis which the researchers would not actively participate in the online study. However, they would focus on the studies of information patterns on websites, interactions on discussion groups through observation. They may analysis those studies about helping mechanisms, and content of online self help groups for some patients like colorectal cancer, breast cancer, Alzheimers disease, and eating disorders. Second is the active analysis which is the researchers would participant in such internet communications. That means researchers try to be a participant to communicate with others. For instance, researchers would determine whether the responses to healthcare questions on the Usenet accurate or not. And the third type is that researchers would identify themselves as and gather information by using different forms of online methods. They may include online semi structured interview, online focus groups, or internet based surveys or use the internet to recruit participant for traditional research. Therefore, it is a more diverse way for researchers to use. Words: 213 Research into Internet communities blur the boundaries between public and private space. Describe the issues identified in the article. (400 words) In the article, it stated there is a difficulty to dichotomize the boundaries between public and private space appropriately during the process obtaining an informed consent from research subjects. In fact, research into internet communities is quite different to the traditional research for obtaining informed consent. Traditionally, informed consent is required when the research is occurred in a private context where individuals are expected there is no observation or reporting is taking place. If it is a public space, the research about natural observation is acceptable without obtaining consent from those subjects. And it does not require Research Ethics Board to review when the research is about observation, as it can be expected participants are seeking public visibility. Therefore, it has more clear boundaries between public and private space. However, research into internet communities may blur such boundaries as people participate in online discussion groups cannot be assumed to be seeking public visibility. And there are various ways of defining public or private space from researchers and internet communities users. Here, some issues are identified which relate to how to perceive the level of privacy in internet communities. Firstly, it noted that most of the subscribers are likely to see the group as a private space in cyberspace when a subscription or some form of registration is required to access a discussion group. Therefore, when there is a registration in that internet community, it is a private space. Secondly, it is pointed out the numbers of (real or assumed) users of a community determines how a public is. The public space is perceived to be a posting to mailing lists with 10 subscribers here is different 100 or 1000 subscribers in mailing lists. However, the problem now is that it is impossible to determine the actual or assumed users when sending messages as some messages may store in web accessible archives. Therefore, using the number of determining the space is public or not may cause the blur of boundaries. Finally, the perception of privacy sometimes is depended on an individual groups norms and codes, target audience, and aim may lay down in the frequently asked questions or information files of internet communities. In this way, it is firstly not easy for researcher to distinguish whether it is a private or public space. More importantly, researchers cannot access to those individual groups as they have set some norms and policies which not allow them to observe those subjects even researchers interested in. For example, a self support group of sexual abuse survivors has a group policy not allow those who were not sexual abuse survivors participating in. On the whole, research into internet communities blurs the boundaries between public and private space where it is difficult to determine these two spaces appropriately. The article mainly identified some issues about the level of privacy or the types into internet communities are various. Words: 480 Using an example of an internet community familiar to you, how might informed consent be obtained to study that community and discuss any problems in the methods you suggest? (800 words) Internet communities provide conveniences and rich information for qualitative research. However, how informed consent might be obtained is a problem that researchers encounter. Here, an example of internet community will be used to show the method of obtaining informed consent. And also discuss the problem may rise. One of the internet communities I familiar to is the discussion board from Facebook. It can connect many of different self support groups. Particularly, an example of support group that I know is the SoulTalk which has established within Facebook. SoulTalk is a non-profit organization with website and discussion board in Facebook. It provides professional, personalized care, support and resources for women share with emotional or relationship crisis. In the discussion board, it is a private group which only opens for its members to share emotional and experiences. Moreover, there are professional counselors helping members to solve problems. There are about 20 members within this discussion board, which they share their experiences about emotional problems. For those who are not the members can only view the basic information and no sharing is allowed. For someone who wants to access this discussion board, they can request for join it but should be confirmed by the group administrator. At first, we should register to be a member of Facebook. And then we can be the member of that community. While the researchers want to study this community, they may firstly need to register to Facebook and then wait for the confirmation of this community. Since this discussion board is a private group, it can be expected that all the information and data from the members are confidential, and they are not seeking public visibility. Therefore, informed consent is required to study this online community. First, as suggested by McCleary (2007), getting permission to enter the group from the administrators is necessary when studying that community. Since they know that community better than researchers, therefore, it should be a better way to understand the group norms or standards from that community, and what would be the best way to obtain consent from members. To obtain the permission from the group organizer, the researchers should explain their purposive of the research, and what form of the members data would be analyzed, and how they ensure that there will be no harm to members. Then, when there is a need to analyze the research result by quoting or using the postings of members, it is important to send emails and ask retrospectively each member of informed consent. Informed consent should note the content of consent form should explain the purpose of the research, and provide a description of any reasonably risks or discomforts to the subjects (Frankel and Siang 1999). Also, it should state the extent of members confidentiality of records would be used and maintained. In this way, members may know more about the research and the possible risks to them, thus, it can give members the considerations whether to withdraw or not. For example, to explain the obtained of their data would only be used in report with anonymity. If members are still refused to participate in, there are also alternatives to them withdraw from the analysis of research. Therefore, the ethical principle of obtaining informed consent can be maintained. Moreover, there will be less intrusiv e in this way and avoid the artificial of the stories made by participants. Indeed, the methods bring some problems. First, the method of asking each member of consent is quite time consuming and unmanageable. As said by Eysenbach and Till (2001), the email address may not be valid and some of them would respond to you. Thus, it may cause some troubles where researchers do not know the email is valid or not. And it is quite difficult for researchers to receive all the consent forms and analyze the result. It generally would be a problem of obtaining informed consent. Also, there would be also a problem that it is possible the administrator does not allow to access the discussion group where the researchers are interested in studying that issue. Therefore, it brings disadvantage to researchers. Besides, even if the administrator allows researchers to enter the group, it does not mean that all of other members agree their information is disclosed. Although researchers may try to conform to the ethical principles to obtain members consent, some of the members indeed do not expect and want to be research subjects. They may perceive researchers as intruders as a result of damaging that community. For example, after the members knowing there are researcher lurking on the discussion board, they may decide to leave the community. Therefore, it is a possible problem that this method of informed consent brings out. On the whole, researcher can identify whether the discussion board as a private space from the example because it has stated that the board would open to non-members. So, it is clear for researchers to follow the ethical principles. However, it still brings problems that cannot be solved during the process of obtaining informed consent which the above have stated. More importantly, the deeper problem should be considered is there is no a consistent guideline to define the boundaries between public or private spaces. Therefore, it brings difficulty to researchers when conducting online research particularly the different level of measuring private spaces. Words: 885 Total words: 2060

Japanese Auto Manufacturing :: essays research papers

The Road to Japanese Automobile Manufacturing Dominance Japan was devastated at the end of World War Two. Although the automobile industry wasn’t as heavily hit as some of the other industries, there were some severely hindering effects on production. Steel and other materials were difficult to obtain causing production to drop 50% by the end of the war (Chao, 1997). Now they are the leading automobile manufacturers in the world. Japan is the epitome of car manufacturers.   Ã‚  Ã‚  Ã‚  Ã‚  Japan had a big ditch to dig themselves out of. First of all to enter into any kind of production they had to get permission from the General Headquarters of the Allied Powers of G.H.Q. This entity regulated trade of the Japanese until 1955. They allowed for as many as thirty manufacturers to enter the production of trucks in 1945, and in 1947 as the ambitions of the industry increased they allowed manufacture of small passenger cars (although limited to only 300 cars per year). With such small potential for production there was mass unemployment and the manufacturers had to take on the repair of their own damaged vehicles.   Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚  Consequently, in 1949 with the tight government finance and banking policies adopted (to suppress inflation) Japan was hit with a massive recession. It was a real blow to the automobile industry; manufacturers had to cut wages and layoff workers. From 1949 to 1950 employment in the automobile industry was slashed by 23% (6,200 people). The labor unions confronted the management of the car makers, and all the manufacturers were hit with the longest strikes in Japanese history.   Ã‚  Ã‚  Ã‚  Ã‚  Japan struggled through the early 1950’s, and in 1955 the â€Å"Post-War Era† officially ended. With the G.H.Q. out of the picture the Ministry of Transportation announced the People’s Car Plan, which gave Japanese auto manufacturers an excellent opportunity to develop new original cars of their own. The plan was eventually be scrapped because the manufacturers thought that proposal’s requirements would be â€Å"impossible to manufacture with the performance and sales price requested† (Shimokawa, 1994). The People’s Car Plan did influence competition to market new products and it gave primarily three-wheeled vehicle makers a way to enter the four-wheel market. Suzuki, Fuji (Subaru), Mitsubishi, and Toyo Kogyo (Mazda) all entered small cars into the market almost immediately.  Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚  Moreover, the first two small cars that really made a name for themselves were the Toyota Corona and the Nissan Bluebird. Of course 90% of these cars were used for business (Rinehart, 1997).

African American Museum Essay

I firmly believe that the point of visiting a museum is to educate one on how things once were in the past through its display of artifacts, exhibits, art, cultural objects, etc. Its purpose is to let you imagine what it was like during a time you were not apart of or, in some cases, allow you to look back at a time you were apart of when you were very young. The African-American Museum of Long Island did a great job at presenting some of the many African-American contributions to society. In addition to presenting contributions from the African-American community, the museum was able to show us some of the struggle they were required to overcome as well. My favorite possession of the museum was Scott Joplin’s piano. Scott Joplin was dubbed the â€Å"King of Ragtime† during his musical career. I felt that it was so cool they somehow were able to get their hands on that piano. When I asked my tour-guide the value of the piano she told me that it was invaluable and that nobody can put a number on it. The only way to determine its value is to put it through an auction and see how much collectors are willing to pay for it. I think the reason for that is because its such an important part of African-American history. How could you put a value on that? I feel it would be impossible to. Another part of the museum I really enjoyed was the mural that an African-American carved out of a tree. The mural was his interpretation of the history of African-Americans. In the beginning it showed how they were all peaceful in Africa and their lives before they ended up being taken into slavery. In the next section of the mural it showed ho w they were forced into slavery, it even showed other African-Americans taking part of the slave trade which is something I, and probably a lot of individuals, never knew. The last part of the mural showed African-Americans in a pretty successful state in nice, fancy suits around family members overlooking the past. I interpreted the last part of the mural as African-American life finally starting to get better with them remembering the past and admiring their ancestors for their struggles to get them where they are. I could not believe how detailed a person could make a mural like that out of a tree. It was truly amazing. I can not imagine the time and dedication that person put into it. I am sure they are proud of where it is being displayed. The main exhibit was filled with many beautiful paintings by Ernani Silva. These paintings were meant to portray African-American life in Rio de Janiero, Brazil. These paintings were unlike any other paintings I have seen. They sort of came off the display to the point where I wanted to touch them so badly because it was really cool. However, I thought it was best if I did not touch anything in there. My favorite painting in this room was the painting of the Jazz band playing music in the streets with a crowd around them. This painting revealed some of the Brazilian culture and how they were forced to practice it on the streets because they were people trying to suppress their beautiful culture. In the room next door, they had a nice exhibit of Rosa Parks that showed the role she played in the Civil Rights Movement with what she went through when she infamously would not give up her seat in the â€Å"white section† of the bus. It also showed how it ended up leading to the famo us Montgomery Bus Boycott. I thought the coolest part of this exhibit was the fact that it had the only known picture of Rosa Parks with her husband together. Not that it has any historical value, but I thought they were a great couple and that they looked very happy together. Another interesting was the painting called â€Å"The Door of No Return†. This was a painting of an open door from a slave ship when they arrived in America. The door led to the fate of the African-Americans which was the harsh conditions and treatment they were about to endure on the cotton plantations. In addition, there was another painting right next to â€Å"The Door of No Return† that showed how the African-American slaves were packed into the slave ships. They literally would have had more room in a coffin than they did on the slave ships. This was the reason why so many African-Americans died on the ships because of disease. I really felt that I learned a lot at my trip to the African-American museum. I enjoyed my time there a lot because my tour-guide was extremely informational and my brother and I were able to interact freely with her. I was able to see some artwork and other cultural displays that I thoroughly enjoyed. The people who worked there were very friendly and spoke to us about our African-American classes we are currently taking. I am happy I had the opportunity to visit this museum.

S iii)Ground Code: #include int timeCount = 0; interrupt[TIM0_OVF] void timer0_ovf_isr(void) { TCNT0 = 6; if(++timeCount == 1000) { PORTA =PORTA ^ 0x01; timeCount = 0; } } void main(void) { DDRA = 0x01; PORTA = 0x01; TCCR0 = 0x02; TIMSK = 0x01; #asm(sei); while(1); } Description: A variable timecount is initialized to 0. In the main function the LSB of PORTA is chosen for output and it is set to 1. Then the TIMER COUNTER CONTROL REGISTER (TCCR0) is initialized in such a way that divide by 8 (CK/8)clock source is selected again the â€Å"timer interrupt mask is set to enable the timer0 counter. #asm† is a assembly language instruction „sei? stands for set enable interrupts to enable all the interrupts. Finaly ainfinite while loop. Then the function with keword interrupt is created. This function will be called automatically when the timer0 overflow interrupt takes place. This function returns nothing, since it is not called by any function and you cant pass any thing to f unction for the same reason . The timer0 is initialized to 6 in this function . As we have chosen ck/8 system as mentioned above and the clock frequency is 4 Mhz that? s why 4/8 Mhz so 500 Khz(0. Mhz) will be the effective frequency so for one tick of counter 1/0. 5 micro sec are required(1/freq. = time) that equals to 2 micro secondes. A timer can count 256 that? s why total of 256*2 that is 512 micro seconds are required . So to make it a round figure i. e. 500 microsecs we Mithibai College:-MSC COMPUTER SCIENCE PART II 5 have to omit 6 ticks of counters that is why we set timer (TCNT0 =6) to 6 so that it ticks from 6 to 256 hence ticks effectively for 250 times (250*2 = 500). and covers 500 micro secs ,when timecount is incremented up to 1000 (1000*500 micro secs = 0. secs). And led toggles after 0. 5 secs.

Corporate Social Responsibility and Carroll Pyramid Essays

Corporate Social Responsibility and Carroll Pyramid Essays Corporate Social Responsibility and Carroll Pyramid Essay Corporate Social Responsibility and Carroll Pyramid Essay The global financial meltdown uncovered many social norms previously unimagined. The number of people who lost their Jobs due to the financial situation is appalling. Interestingly, this does not mean that multi-national corporations are necessarily suffering. Most of the established companies with branches all over the world took the excuse of the financial breakdown to benefit. All of a sudden, it was okay to lay off people on the pretext of financial gloom. This means that a few people were benefiting from the woes of a thousand more. The issue of corporate social responsibility presents itself in this situation in that, the multi-corporations are run by a board of governors. The board of governors is usually composed ofa few individuals that call all the shots. It is common knowledge that these corporations employ a huge number of persons in many sectors of the economy. When the profits of these gigantic companies fail to reach a certain goal, the running costs of the business have to be checked. This is why, the few persons at the top, not wanting to lose, resort to firing some people. This is done so as to maintain the profits at a certain level. The problem is that when all of the multinational companies resort to firing a few employees, the net effect is that, a large number of persons end up losing their Jobs. Corporate social responsibility ensures that corporations the world over are engaged in other activities that give back to the community (Crowther and Rayman-Bacchu 172). Many activities that are considered helpful include; organizing activities that seek to involve the community in such events as fund raising for the eedy, events that seek to help out the disadvantage in society and other similar activities. In the financial and corporate world, corporate social responsibility a given with a positive impact on performance. There are, however, several factors that show the need for corporate social responsibility. The first factor is population. The expanding population in developing regions will create larger markets dominated by younger individuals with questionable access to the developed worlds standard of living. Statistics show that more than eighty five percent of the worlds population will ive in developing countries by 2025 (Crowther and Rayman-Bacchu 165). This presents a challenge to companies seeking to involve themselves in corporate social responsibility, since it is clear that a lot of financial support will be required for these populations. The second factor is wealth. Despite the fact that global wealth is rising, the income gap has grown wider, threatening civil society. Seventy eight percent of the world can be classified as poor, with eleven percent in the middle class, and only eleven percent can be classified as rich. Each and every company should strive to be nvolved in attempting to balance this distribution of wealth. The trend of the rich growing richer while the poor grow poorer should be eliminated, since it is unethical for some people to have so much, and others to have nothing at all. The third factor is nutrition. There are millions of people who are malnourished, amidst an abundance of food. Thousands die of hunger every year, while rich corporations blow millions on fancy holidays for their executives. It is crucial for each company to take time and retlect on the finances it spends on benefits tor its executives, as compared o that spent on helping the needy in society. While these benefits are vital for employee motivation, they should not be taken overboard at the expense of the suffering masses. Education is another critical factor that should be considered in the design of corporate social responsibility programs. Basic education is widespread, but opportunities for learning continue to elude many. Over one hundred million children are not in school, with ninety seven percent of these being in developing countries. One in every five adults globally is illiterate, which are taggering fgures given the widespread opportunities to learn available today. Corporate are faced with the challenge of promoting education by setting up schools, and funding educational development programs. Education can also be encouraged by taking in interns and trainees and giving them an opportunity to learn the tricks of the Job, which will enable them compete fairly in the corporate world (Crowther and Rayman-Bacchu 169). In conclusion, this paper has shown that corporate social responsibility is a vital element for nay business corporations. It has been shown that here are many different areas in which a company may choose to focus its corporate social responsibility. The first area of focus in corporate social responsibility is with regard to the environment. Other areas that should be considered in the development of corporate social responsibility programs are education, health, nutrition and employment. Social responsibility investment combines investors financial goals with their obligation and dedication to factors that ensure the well being of society such as environmental friendly practices, economic growth and ustice in society (Anderson 9). These elements are not only aspects of corporate social responsibility, but also a show of the ethical standards of a company. It is unethical for some individuals to own so much and earn so much, at the expense of other suffering members of society. It is also unethical for companies to engage in environmentally degrading practices that result in illnesses and loss of life. It can be concluded that Social corporate responsibility and the maintenance of high ethical standards is not an option but an obligation for all business. Anderson, Jerry.
