The Theory of Leisure Class Research Paper Example | Topics and Well Written Essays - 3500 words

The Theory of Leisure Class - Research Paper Example The present inquiry is not concerned with the beginning of indolence, nor with the beginning of the appropriation of useful articles to individual consumption (Hinkrl and Fotos, 2002). The point in question is the origin and nature of a conventional leisure class on the one hand and the beginnings of individual ownership as a conventional right or equitable claim on the other hand. The early differentiation out of which the distinction between leisure and a working class arises is a division maintained between men and women's work in the lower stages of barbarism (Hodgson, 2004). Likewise, the earliest form of ownership is an ownership of the women by the able-bodied men of the community. The facts may be expressed in more general terms, and truer to the import of the barbarian theory of life, by saying that it is an owner of the woman by the man. There was undoubtedly some appropriation of useful articles before the custom of appropriating women arose (Michelman, 1969). The usages of existing archaic communities in which there is no ownership of women is warranted for such a view. In all communities, the members, both male and female, habitually appropriate to their individual use a variety of useful things; but these useful things are not thought of as owned by the person who appropriates and consumes them (Mitchell, 1936). The habitual appropriation and consumption of certain slight personal effects go on without raising the question of ownership; that is to say, the question of a conventional, equitable claim to extraneous things. The ownership of women begins in the lower barbarian stages of culture, apparently with the seizure of female captives (Rosenberg, 1936). The original reason for the seizure and appropriation of women seems to have been their usefulness as trophies.

America’s economy after the Civil war Essay Example for Free

America’s economy after the Civil war Essay After the Civil war in the United States, Corporations grew significantly in number, size, and influence between the 1870s and 1900s. Big business impacted America’s economy, politics and as well as the Americans responses to these changes. Big business began when entrepreneurs in search for wealth and success combined their business into massive corporations. Vertical and horizontal integration were tactics used to make business grow faster. Vertical integration is the acquiring of material from the bottom up for means of production, for example Carnegie used this strategy. Horizontal integration is the controlling of other companies that produce the same product, which Rockefeller used. The corporations were so large that they could and some did, force out the competition which resulted them in gaining control of that particular market. This allowed corporations to set the prices they desired, which affected the consumers pocket as that was the only place they could obtain the product or good from. Business men who ran these large industries became extremely wealthy, powerful and influential, often at the expense of many poor workers, and much of the public saw them as robber barons who exploited workers, in order to accumulate immense fortunes. For example, in 1882 Rockefeller solidifies his control by establishing a monopoly or trust, which centralized control of a number of oil related companies under one board of trustee. By 1879, Rockefeller controlled 90% of the county’s oil capacity. As a result of this, companies in other industries quickly imitated this trust model and used their broad market control to raise prices. Also in document A, statistics are shown of the index prices to the average prices during a certain period of time and it is evident that as the years progressed, the cost for food, fuel and lighting decreased significantly but the cost of living of also decreased but not to the degree of the above mentioned. Trusts were a common way to force out the competition and control a market in the 1800s. Big business also impacted America politically as seen on document D. This political cartoon shows wealthy industrial owners, which are taking up most of the space in the US senate and are coming in from a door that is labeled â€Å"Entrance for monopolist† and all the trusts are lines up to enter. Also, in the left corner there is a door labeled â€Å"People’s entrance† that had a â€Å"closed† hanging from it, which clearly shows that the people do not have a say in the senate. This means that industries have a great amount of power in the senate as well as a big impact politically. Also in document B, from George E. McNeill, a labor leader, is a short passage about â€Å"The problem of today† in 1887. He starts out explains how the railroad president holds so much power that it is almost as if he were the king of the railroad. The article states that the railroad king collects his tithes, which is the 1/10th annual income given to clergy and to support the church, by lowering the worker’s wages. He also has the power to fire anyone, take away their income, delay trial on a suit at law, and postpone judgment indefinitely. This shows the amount of power in his hands, and how he has a say in politics and court. At the end, McNeill states, â€Å"In his right hand he holds the government; in his left hand, the people† to show the sense of control he has in both areas and the degree of his influence on both, the people, and his government. American’s responses to the growing corporations were evident in document C. In this document David A. Wells claims that individualism or independence of the producer in manufacturing has been in great degree destroyed as well as the pride workmen took in their work. Also, he says modern manufacturing systems have been brought into a condition similar of that of a military organization. This shows the rigidness of the bosses and the demand for their work to be perfect. It is also mentioned in this document that as a rule, workers are only good for one thing, and then are useless once there is no more work of that kind. Lastly, the works are no longer independent. But depend and have to obey rules to keep progressing. In document E, by Andrew Carnegie, he states that to set an example of modest he has to provide to those who depend on him. Andrew Carnegie of the steel industry donated much of his wealth to building libraries, schools, and universities to support the less fortunate or poor. The growth of corporations evidently impacted the economy and politics, as well as the American responses to these changes, in 1870-1900.

Cultures And Values In Human Society

Cultures And Values In Human Society Culture is the essential part of the humans society. Every person is spending his or her life within a certain cultural community. It frequently defines what kinds of person a man or woman is and what values will they have. Does the cultural environment have a direct effect on the values within a community for anthropology, psychology and sociology? Let us discuss this topic step by step. To understand it better, we can at first define what the cultural environment is and what influence it has on people within it. The very nature of the cultural environment is cultural and social aspects. It is could also be called a social context and sometimes milieu. It is a culture of a society or a group where a certain person is living or getting an education; it is institutions and people who interact with a certain human. By interaction we can mean not only different types of personal communication (like on a workplace, in class, with neighbors etc.); people could also communicate with each other by means of different communicational media (like phone, internet, newspapers, television etc). In spite of non personal type of the communication, people whom a man or a woman meets in internet can have an influence on his or her values and point of view. Also television and other mass media form our perception of life and other people little by little. This type of interaction we c an call one way or anonymous. It does not always imply the equality of the social status. Thus, the concept of a social environment is wider that the concept of a social circle or a social class. Nevertheless, it is common that those people who have the same social environment start having a sense of solidarity. They easily help and trust each other; also they tend to create a social group. As a result, those people will always have a similar way of thinking and similar patterns even if they make different conclusions. It shows us that people depend on society and culture around them very much whether they recognize this fact or not. Let us briefly define what culture itself is. It is going to help us understand what kind of effect it has on the values within a community for anthropology, psychology and sociology. There is plenty of information about culture and different consequences of it. It is impossible to transmit a culture through genealogy. Culture is not something innate; culture is something that everybody should learn. Different facets of it are interrelated; a culture is spread by those people within a group. Nowadays different cultures could easily exist within a country side by side (like it commonly happens in African countries). According to Hoebel (1960), the definition of a culture is following: The integrated sum total of learned behavioral traits that are manifest and shared by members of society. According Lawton (1975), culture includes age grading, religious rituals and athletic sport. According to Frow (1995) there are traditional differences in task and doing business were breaking down and this meant that standardization rather than adaptation is becoming increasingly prevalent. Probably, a culture is one of the most significant environmental variables that should be considered within a global marketing. Often a culture could not be freely overlooked; it often hiding from a view. Culture consists of some elements; they are language, aesthetics, religion, values and attitudes, education, social organization and material culture. It is necessary to discuss briefly every element of it. Material culture includes communications, power, transportations and others. Language is the next aspect of culture. It is a reflection of the values and nature of a certain society group. It could be sub-cultural languages, for example, dialects; in some countries it could be two or even more languages. Aesthetics includes art, dancing, arts-music. It concerns good taste, beauty, form and color of it. Education, as it is easy to see, includes the transmission of ideas, attitudes, skills and training in certain disciplines as well. Moreover, education serves as a transmitter of cultural and social values. Sometimes a child was introduced to the cultural value by school or later by university. Religion gives the humans behavior the best insight and as well it helps us to answer different questions, for example, why people behave n this way and not in another. We can see that culture is a complicate conception; it includes different aspects. What can we say about values conception? What is commonly meant by values? Shortly, by values a person may mean something that is really matter to him or her. It is beliefs and ideas somebody holds as special. Social and cultural environment forms ones values. Home, church school there are just some places where people could study values that are common for everybody within their cultural environment. Teachers, friends, parents are forming our personal system of values from day to day. As a result we have personal values. Arts et al. (2003) summarized that they consist of something that we accepted from people around as and that part that came with our own life experience. It is too compulsory to accept everything a person is hearing around him or her; nevertheless, values of cultural environment around us has its strong influence on our own system of values. Now, when we recognize what values, culture and cultural environment commonly mean we can examine the direct effect that the cultural environment has on the values within a community for anthropology, psychology and sociology. Before discussing the influence of a cultural environment on a person according to anthropology let us briefly mention the definition of the science. Saying shortly anthropology is the inquiry of humanity. Its origins throw back in the social sciences, natural science and humanities. The term itself is taken from the ancient Greek language and has two parts: man and study or discourse. The matters of anthropology are how do people behave, what are their physical traits, why we can see differences and variations between groups of people, and finally who was the ancestor of the modern humans. Anthropology is commonly divided in to four fields; they are cultural, or social, anthropology, linguistic anthropology, archaeology and biological, or physical, anthropology. We can see that anthropology itself is the science that studies social and cultural values, differences, origins, roots etc. Thus, it is important to talk about the influence of culture environment according to this certain science. According to anthropology, a culture could be seated deeply; unprepared person could take some type of a culture like something senseless, strange and even cruel. Let us give an example. According to the Muslim culture a woman must cover her face with yashmak and hide herself from any alien. Nilaweera Wijetunga (2005) emphasized that this custom could appear strange and senseless to any person from Europe, United States or numeral other countries where people flaunt a womans form openly. Here is another example of the opposite culture. In some African countries (like Congo, Kenya etc) women do not wear top cloths. Oyeshile (2004) explained this fact that according to their culture, their traditions and according to their hot climate they do not consider the top of the female body something that they should cover or hide. There are many other different examples of things and customs that are unacceptable and even criminal in one part of the world; at the same time at another part of it people consider it the culture and commonly do it. Summarizing this short extract we can see that cultural environment have a direct effect on the values within a community for anthropology. Continue the two examples above, a woman from the African country where there is not common or compulsory to cover her body with upper wear have values that are different from the values that are precious for a woman from a Muslim country. If those women could try to explain themselves their culture, values and reasons why they are keeping those culture values they would hardly understand each other. It is common that Muslim people condemn women from Europe and America. For them even the most modest and restrained American female seems to be a woman without culture values because she shows certain part of her body What can we say about the influence of the social environment on personal values for psychology? What is psychology? It is the science of the humans behavior and mind. This science is an attempt to understand humanity by exploring certain specific cases and by discovering some general principles as well. One of the main goals of psychology is to benefit the society. Scientists who involved in it we can divide in to some groups: cognitive scientists, social scientists and behavioral scientists. Among others, social behavior is among different subjects of psychology. The science of psychology explores following concepts: emotion, cognition, phenomenology, perception, attention, brain functioning, behavior, motivation, personality, unconscious mind and interpersonal relationships. As anthropology, the science of psychology is a social science and it has a strong connection with social environment. According to psychology, some type of behavior could be considered normal and other type c ould be considered abnormal. Commonly, humanity has the same nature. For example, murdering and cruelty is considered abnormal in every social group and community. Nevertheless, within some cultures the conception of cruelty may vary. Let us give an example. In American and European countries violation in any form is unacceptable even within a family. Thus people who keep doing it to others would consider psychologically abnormal. According to the culture of some eastern countries, especially countries with Muslim culture, a husband can beat his wife or punish her or in any other way if she does not satisfy him. What kind of misdeed could a wife do? She may cook a food that her husband does not like; she may say a word that her husband could consider unacceptable. People within the community with such culture are considered psychologically normal even if they commit violence every day. According to their culture cruelty is acceptable. A woman is expecting for it and she has no even right to complain. According to the example above we can see that psychological situation within a community could have a strong negative effect on personal values of a human. A person can look at low values of members of the community around him or her and subconsciously this person could understate those values that he or she had before. Psychologically people inclined to depend on society. That is why we can state that the cultural environment have a direct effect on the values within a community for psychology. Sociology is the last science that we are going to discuss. It studies the society using different methods of critical analysis and empirical investigations. This science refines and develops knowledge about the activity of human society. One of the aims of sociology is to achieve the social welfare with the mean of the knowledge. Mancheno-Smoak et al. (2009) stated that the field of interests in sociology varies from the micro level of interaction and agency to the macro level of social structures and systems. It is a very broad conception that is focused traditionally on social class, religion, social stratification, social mobility, secularization, deviance and law. It includes all spheres of peoples activity. It is interesting that sociology studies different types of interactions between people. We are living in the age of the world wide globalization when the whole planet is becoming one big house. Different cultural and social communities are not staying separate from each oth er like it was some hundreds years ago. People are moving, migrating and spreading their culture and different values among other societies. Why can we state that according to sociology, the cultural environment have a direct effect on the values within a community? First reason is that people like to communicate with each other. It means that they getting some new knowledge and values. Roniger (1995) declared that when representatives of different cultures are staying in contact for some time they will get used to new values. It will stop being new for them. New cultural values will become common and according to sociology people will start accepting it in their lives. In some time they would not remember that one or another culture or value was not imparted to them. And it is the second reason why the cultural environment has an effect on values of people for sociology. In other words, when people move from one place to another they create a new social group with mixed culture and values. In conclusion of all factors and aspects that we discussed above we can see that anthropology, sociology and psychology are connected between each other. These three sciences are all about the human nature, culture and community. They are examining interactions and cooperation between different people; we can state that the cultural environment have a direct effect on the values within a community for anthropology, psychology and sociology because according to these sciences it is up to peoples nature to take something new from others. According to religion, human society was created as one big family. Let us agree that this statement is right; thus, we need to accept that people within a social community have a direct effect on each other in the same way in which members within an ordinary family have. Every science that we discussed has one main aim to make our society better. We need to remember that it is up to everybody to help in achievement of this aim.

Interview Paper Essay

One day forty four years ago, a baby was born in Texas. He was growing up healthily in the warm Texas wind and heat year after year. His name is James Cambell, a man who never stopped chasing his dream with great zest although he is now forty four years old. Spring has always rightly been identified with youth, and the sorrows of youth are poignant and unrepeatable, but he never thinks it is too late to achieve something, a dream or a goal, could be very large or very tiny. When James was young, he had always had a dream that he could travel across the country and now he still has it. Ever since high school James loved jogging and fishing. In the 1980s, a lot of electrical equipment and electronic devices came into this world. At this time, many experts and scientists were predicting the 21th century would be the internet age. As he was a boy, no one could stop James Cambell to be attracted to these electronic devices. So, he started playing and learning about these devices. After he finished his schooling, he got a job in electronics. Many years later, he fell in love with a girl who later became his wife. Everything is impermanent and can be changed. Marriage or divorce and its many ups and downs, still exercised a powerful hold over newspapers, magazines, and the airwaves. Unfortunately, James Cambell was one of them. However, divorce is not always a bad thing. It could be a good in that you as an individual get less stressed and more free time in life. Today, he’s still working in the electrical field and he thinks it is an appropriate time to get more knowledge about electrical technology. Consequently, he’s at HCC now studying Electrical Engineering. In our youth, everyone makes mistakes, and wondered what the world had in stock for them. They too might have had confusion about the future. Brian Mosley was born in Houston. Without exception, he made a so-called mistake when he was young. Life can sure throw a curve ball when you least expect it. A newborn entered his life at age eighteen and had to find work to support him and his new family. When I asked him, â€Å"have you ever had any regrets about what happened?† He said he never thought it was a mistake because he looked at the situation through optimist eyes. If there was only half a cup of water left, an optimistic person may cheer for it because they still have the half. Obviously, Brian was an optimistic person that  never felt unhappy or sorrowful. There is no denying that, most optimists have a high happiness index, which can hardly be experienced by pessimists. His attitude had moved his wife and parents strongly so they too can view life in the same perspective. As a result, the atmosphere of optimism and happiness had been naturally set up and his mom aided to him to take care of the baby. Fourteen years later, Brian’s second boy was expectably born when he was thirty two years old. Today, he is a thirty nine years old man with less pressure and more freedom. His work schedule allows him to attend HCC to continue receiving a higher education to later support his family even further. Now he’s studying physical therapy for his interest. He hopes he can travel with his family on road trips across the whole country in the upcoming years. There is always a lot of fun in an extended family. Sometimes people may squabble but never take it to heart. Twenty seven years ago, Michael was born in Houston and he had two brothers and three sisters. Unfortunately, he was oldest child had to take care of them and forgive their mistakes. In other words he had to start learning more than his brothers and sisters such as doing housework. In such a situation, he had been independent earlier than others. Every time when Michael was awake dead at night he always felt lonely and so he would ask himself what is needed of him. Sometimes, he still felt lonely, but is loneliness a terrible thing? Obviously, the answer is no, because loneliness also could bring something good to him. Because of lacking help from others, he became prone to dealing with all kinds of situations by himself. Thus, he would be more independent in life and he can endure more setbacks and pressure. Now Michael likes watching comedy and shopping with his friends. He has a three years old daughter. And he’s studying business in HCC to get a more interesting and better job.

Gun Control misc8 essays

Gun Control misc8 essays Since the days of the pioneers of the United States, firearms have been part of the American tradition as protection and a means of hunting or sport. As we near the end of the 20th century the use of guns has changed significantly. Because of fast and steady increase in crime and the fight for the right to own a hand gun, the introduction of legislation for gun control, to try to reduce the crime in the United States, has been a hotly debated issue in recent years. Although many people feel that gun control violates the right of the people, given in the second amendment "the right to bear arms", controlling distribution and sales and the registration of guns and gun owners is necessary because of the homicide rate involving guns and the violence by criminals using guns. Many people feel that gun control violates the right of the people given in the second amendment the right "to bear arms". Opponents of gun control, including the National Rifle Association, better known as the NRA, argue that the "right To bear arms" is guaranteed in the second amendment of the Constitution of the United States of America and licensing restrictions penalize law-abiding citizens while in no way preventing criminal use of handguns. It is also argued that by making it difficult for guns to be bought and registered for the American public there is a threat to the personal safety of American families everywhere. However controlling the sale and distribution of firearms is necessary because of the homicide rate involving guns. In 1988 there were 9000 handgun related murders in America. Metropolitan centers and some suburban communities of America are setting new records for homicides by handguns. Larger Metropolitan centers have ten times the murder rate of all Western Europe. For example in Washington,D.C. there was an estimated 400 homicides including guns. In addition gun control has been seen as necessa...

6 Proven Ways for Women to Get a Higher Salary

6 Proven Ways for Women to Get a Higher Salary By now, you’ve likely heard the rather grim statistics: on average, women earn less money than men for comparable jobs. In 2015, women made 80 cents for every dollar earned by men in the same roles, according to the Institute of Women’s Policy Research. The whys and hows of this salary difference is kind of a political football- everyone seems to have an opinion why that is, or even whether the gender gap truly exists. While that discussion is for another time and place, let’s go with the stats on this one, and look at how women can overcome challenges and pay disparities to improve their own salary outlook. 1. Be your own best advocate.The first thing you need to do is understand that this is your ball to carry. No one is going to come along with a big check and say, â€Å"You know what, you deserve more money. Take this!† No matter how awesome you are at your job, or how above and beyond you’ve gone lately, it’s most likely going to be up t o you to help ensure that you’re being compensated as much as possible.This is something I’ve struggled with personally throughout my career. I’ve always had the mindset of, â€Å"I’m gonna work really hard, and be really great at this, and people are going to notice and reward me accordingly.† Guess what? Praise and acknowledgment don’t necessarily translate into higher salary. Once I realized that it was on me to make sure I was making what I was worth- and taking positive, proactive steps to make that happen.2. Know your market value.This is key. Increasing your salary is going to be very difficult if you don’t really know what other people are making in your field and at your experience level. If your ask isn’t reasonable, your chances of getting a bumped-up salary are somewhere in the area of â€Å"laughed out of the room.†In another hard lesson in my career, a colleague who was leaving our company let me know what he was earning there (we had the same job title and responsibilities). It was significantly more than I was making at the time, and I was floored. When I brought this up to my boss, her response? â€Å"You weren’t supposed to know that.† Maybe not, in some unspoken â€Å"talking money is rude† kind of way, but I did know it, and it gave me a number to aim for when it came time for the annual review and salary increase.You shouldn’t have to rely on the grapevine to know what others are making, but you also probably shouldn’t walk right up to your coworkers and demand to see their pay stubs. We have tons of great tools available to us to find out what others are making in our industry, and what we can reasonably expect based on experience, location, etc.:Salary.comPayScaleGlassdoorYou can use all of these without having a single awkward conversation about salary and personal finances. Don’t hesitate to have as much information at your disposal as possible. And don’t let anyone convince you that it’s rude to talk numbers when it comes to your own career and salary goals.4. Negotiate every time.According to Stanford-based leadership expert Margaret A. Neale, women just don’t negotiate at the rates that men do. And in fact, Linda Babcock, author of Women Don’t Ask, found that while 57% of men negotiate salary, only about 7% of women do. Seriously, 7%! It looks like everyone- men and women alike- should be negotiating more, but especially women. Not negotiating is like closing a door without checking to see if anyone’s there. How do you know if there’s an opportunity to increase your salary if you haven’t even tried yet?And don’t think that negotiation is just for new job offers- you should be negotiating your salary at every chance, including annual reviews, after times when you’ve gone above and beyond at work or taken on new responsibilities successfully, and/ or when you discover that your market value is higher than your current salary level. Whether you’re a negotiation newbie or want to bump up your skills and become a master negotiator, we have plenty of resources for you:Your Comprehensive Guide to Negotiating SalaryHow to Get a Raise at Work6 Tips for Negotiating the Salary You WantThe Super Easy Guide: How to Negotiate a Raise and PromotionThere are also lots of experts online who have honed their negotiating skills, and want to share that information with other women. Resources like MichelleMotivateMe are a great place to start:Once you get over any hesitations about getting in there and playing the negotiation game, you’ll have started advocating for yourself and your salary goals in the best and most direct way possible.5. Think small (company).If you’ve tried negotiating and still fallen short of your salary goals, it might be time to think about switching companies. Hired.com investigated wage gaps at dif ferent kinds of companies, and came up with some intriguing statistics around the unfortunately traditional wage gap. It turns out that smaller companies and startup companies are less likely to have significant wage gaps, compared to companies that were bigger and more corporate, or that had been established longer.The thinking behind this? Small companies tend to have more visibility into salaries, which is an equalizer. If employees know that Frank two desks away is making more for the same job, the company has an employee relations incentive to keep things more equal. The other interesting angle was that startup (or â€Å"seed stage†) companies may have less pay disparity because they have less flexibility in the salaries they can offer employees, so they can’t really afford to offer one employee a drastically different salary than another employee in the same role.So what does this mean for your own salary? You might want to consider whether there are companies in your field that can offer you better salary- less established companies that you may not have considered before.6. Think outside your career box.If you feel like you’re stuck in a pay rut, you might also want to consider a job change. There are growing fields, like logistics/trucking, manufacturing, and information technology, where women are the minority of workers. Many women have the base skills necessary for these â€Å"middle-skill† jobs (which often don’t require a college degree), but just aren’t pursuing them at the same rate men are. If you’re looking for more opportunities to segue into higher-paying roles, one of these industries might be a great path for you. (Just don’t forget to negotiate!)The good news is that statistics may inform us about what’s going on, but they don’t have to define us- or our careers. There’s no reason to accept the status quo when it comes to your own career and your goals. If youâ €™re a woman and you’re interested in boosting your earning potential, you have tools to help you do that. And if more women take control of their salary destiny and start using all of those tools, we can start changing those stats, one closed gap at a time.

Free Essays on Contra Columbus Day

Columbus Day: In Denial of History October 12, Columbus Day, is a national holiday. For most Americans, it’s a day off from school or work. Many communities observe this day with parades and pageants depicting Columbus as a hero, with smiling Indians and brave sailors, with out really knowing what began to happen on that day 500 years ago. Until recently history text books portrayed Columbus as great explorer who discovered the new world. Now we are presented with history that is much closer to the truth. Columbus had an appetite for gold and the possession of land at any cost. This great hero is responsible for the deaths of millions of indigenous people and taking ninety-five percent of their land. This holiday is set aside to honor the man who caused this genocide. What are we supposed to celebrate when it is discovered that the hero of the day is really a monster, not unlike Adolph Hitler? This holiday should no longer commemorate the life of Christopher Columbus. Rather than celebrating genocide we should remember the millions of early Americans that lost their lives. Now that more of the truth has been revealed to this generation, it would be possible to change the objective of October twelfth to a memorial day for the first Americans. There are theories that support the evidence of other explores that discovered America five hundred years before Columbus. Leif Eriksson, a young Viking was thought to have landed in America in 1000 and named it Vinland. Other research indicates that the Muslims crossed the Atlantic Ocean and discovered America in 1150. There is even a record of Chinese settlers in America as early as 499 A.D. by a Buddhist priest called Hwui Shin.

Free Essays on Contra Columbus Day Free Essays on Contra Columbus Day Columbus Day: In Denial of History October 12, Columbus Day, is a national holiday. For most Americans, it’s a day off from school or work. Many communities observe this day with parades and pageants depicting Columbus as a hero, with smiling Indians and brave sailors, with out really knowing what began to happen on that day 500 years ago. Until recently history text books portrayed Columbus as great explorer who discovered the new world. Now we are presented with history that is much closer to the truth. Columbus had an appetite for gold and the possession of land at any cost. This great hero is responsible for the deaths of millions of indigenous people and taking ninety-five percent of their land. This holiday is set aside to honor the man who caused this genocide. What are we supposed to celebrate when it is discovered that the hero of the day is really a monster, not unlike Adolph Hitler? This holiday should no longer commemorate the life of Christopher Columbus. Rather than celebrating genocide we should remember the millions of early Americans that lost their lives. Now that more of the truth has been revealed to this generation, it would be possible to change the objective of October twelfth to a memorial day for the first Americans. There are theories that support the evidence of other explores that discovered America five hundred years before Columbus. Leif Eriksson, a young Viking was thought to have landed in America in 1000 and named it Vinland. Other research indicates that the Muslims crossed the Atlantic Ocean and discovered America in 1150. There is even a record of Chinese settlers in America as early as 499 A.D. by a Buddhist priest called Hwui Shin. With this information, why is Christopher Columbus considered the first man to discover America and why is there a holiday in his name?

Criminology (crime and justic) Assignment Example | Topics and Well Written Essays - 2000 words

Criminology (crime and justic) - Assignment Example Body Before a criminal is finally subjected to any form of corrections, he/she has to go through an entire structure of criminal justice system. The very first contact that a probable offender or a suspect makes with the system of criminal justice system is with the law enforcement agencies such as police who are responsible for carrying out an arrest after investigating a particular deviant act.. The law enforcement agencies are divided into different levels and they deal with different levels of crime. For crimes that do not pose immense threat to the security of a nation and are less severe in nature, mostly fall under the jurisdiction of police, while crimes such as international terrorist activities that pose a threat to the national security are handled by federal level law enforcement agencies such as Federal Bureau of Investigation. The law enforcement agencies that fall under the category of policing are even responsible to ensure that harmony within society members is creat ed and maintained (Stojkovic, 2012, p.58). The policing branch of criminal justice system tries to serve the function of deterring crime by arresting suspects and offenders and presenting them in front of the court of law. After passing through the policing system, the criminals and suspects are taken to courts where dispute settlement arises and administration of justice takes place. Several individuals are involved in the process of courts, these includes: prosecutors, judges as well as defence attorneys. The main duty lies with the judge who has to be objective and assign sanctions to criminals and ensure that the sanctions assigned are in compliance with the kind of crime being conducted and the severity of the crime. The courts of the criminal justice system even operate for serving the function of deterring crime. They do so by allocating severe punishments as well as rehabilitation of the offender. In case of severe punishments, criminals may be sentenced for life time in ord er to set an example for other possible offenders to ensure that future offenders may be deterred from indulging in criminal activity as they may see life imprisonment as a higher risk than the advantage of committing a crime. Once the courts assign sanctions to the offenders, the offenders are then transferred to authorities that are responsible to administer the sanctions that have been levied on the offender. Over the years, the correctional settings and the correctional portion of the criminal justice system has evolved with several changes in techniques of punishment. In previous years, lack of resources resulted in sanctions such as exile as well as execution, much modernized ways of punishments include: community work, jail time, as well as incarceration and rehabilitation. The main function served by this portion of the criminal justice system is to alter the behaviour of the criminals while trying to ensure that they are not released from their sanctions until they are read y to be normal and non-deviant members of the society. The main aim of all these measures of punishment have remained the same over the years. The aim has been to deter crime and to ensure that the streets of a particular nation and the citizens of their nation are safe and secure from criminal activities. Conclusion The structure of

Reward Essay Example | Topics and Well Written Essays - 250 words

Reward - Essay Example A system of pay that targets an individual is based on the accomplishments of only one person. In this case, rewards are determined by the results put on the table. Pays based on performance do not necessarily account for knowledge and competence. High performance is rewarded while low performance is ‘punished’. Moreover, progressive performance given in levels can determine what reward is earned at what performance. Where different incentives are used on different individuals, the reward becomes incentive-based, and it is complemented by self-actualization. A team constitutes a number of people working on clearly defined common goals or objectives. The performance of a team can be rewarded in a number of ways, among them team-based rewards, rewarding individuals constituting the team, and group behavior (Levi, 2010). Rewards that are team-based target the team’s totality and productivity. The performance of the team is attributed to each member, and so are the rewards. Team performance can also be rewarded by considering individual contribution of each team member and subsequently determining the appropriate reward. Finally, group cooperation and motivation can be rewarded subject to the team

How does the rise of ethical consumers effect corporate social Essay

How does the rise of ethical consumers effect corporate social responsibility - Essay Example While taking price and quality into consideration, ethical consumers apply to the decision making process some additional criteria, which may be their priority issues in some cases. Corporate social responsibility (CSR) encompasses the relationship between corporations or other large organizations and the societies with which they interact. CSR also includes all the responsibilities which are a part of these relationships, for both the organizations and the societies. All stakeholders and constituent groups that have an interest in the organization’s operations are included in CSR’s wide and multiple-level definition of society. Corporate social responsibility can be defined as â€Å"the broad concept that businesses are more than just profit-seeking entities and therefore also have an obligation to benefit society† (Werther & Chandler, 2006: 6-7). Strategic corporate social responsibility is the concept that for long-term benefits to the organization, CSR should be made a part of the firm’s strategic perspective and operations. It has been recognized that the activities of an organization influence the external environment, hence it is important that the organization should be accountable to not only its stakeholders, but also to a wider community. This concept initially took root in the 1970s, and grew as a concern for the company as a member of society, with a wider view of company performance including its social performance (Crowther & Rayman-Bacchus, 2004: 3). Though community accountability was acknowledged as essential, the focus of big business on financial results was observed to be an impediment to social responsiveness, especially in the early years of the accountability concept taking shape. There is now an increasing move towards accountability of companies towards all participants, and this recent phenomenon is getting established as the

Discuss the Iranian Constitutional Revolution's causes and outcomes Essay

Discuss the Iranian Constitutional Revolution's causes and outcomes - Essay Example The Iranian constitutional Revolution of 1906 stands to highlight the pivotal moment, that shaped the formation of the modern Iraq nation. The Iranian society underwent a series of changes that affected its power relations, social structure, and the political language (Campo, 2009:55). In addition, the relentless European penetration into the nation led to its subsequent weakening, affecting the economy as well as the traditional elites thus bringing Iran in the doorsteps of the expanding capitalism system (Afary, Anderson & Foucault, 2005:90). This processes led the country into a change of the constitution. This research paper will analyze the chronology of events that necessitated Iran’s new constitutional dispensation, first the birth of the revolution, secondly the causes of the constitutional revolution and thirdly the outcomes of the constitutional revolution. The itinerary of the revolution To begin with, the itinerary of Iran’s constitutional birth traces back to the days of Qajar regime (Sohrabi, 2011:48). A journey shed new light to the country. It highlighted the role of ordinary citizens, peasantry, the status of women, and the multifaceted structure of the Iranian society, in the course of realizing the new law reforms. As stated earlier in the introduction, the new changes in the military, administrative, educational, and judicial reforms led to emergency of new institutions and a new social stratum of intellectuals. As this seemed not going to end, the simplification of the Persian prose, which aimed at articulating it to a new system of historical narration no longer basing on Muslim, was on its way to change the existing social norms (Daniel, 2000:54). As a reason to this, the dominant Iranian conversation or discourse changed. This discourse, which was the bonding element between state and religion, led to the emergency of new relations of power and knowledge. People shifted away from the use of possessors of knowledge to being spiritualists (Katouzian, 2006:105). They now referred to the religious elites. At this level, it is clear that the country was operating on two different and opposing blocs. Qajar regime tried to create social reforms in the existing institutions. The regime-faced collisions even from clergies who had became an important component of the power bloc. As a result, with each group having its own resolutions and visions, the end was a conflict of interest. This slowed down the pace of reforms. The lag in the realization of reforms increased the dissatisfaction between the merchants and the intellectuals. Consequently, this brought uneasiness to the Qajar’s. At this stage, the merchants and the intellectuals opposed the government’s slow pace because they believed they possessed more revitalized ideas. All those who were for the reforms and those who formed the pact of not in support, ganged up to discredit the government due to its despotism of the state (Sohrabi, 2011:66 ). The aftermath of this was the fight that targeted despotism. This brought together even the opposing forces, which prior had diverse antagonistic demands and aspirations. In this emerging discourse, the political space divided into two (Afary, Anderson & Foucault, 2005:114). There was the state on one side and the antagonistic poles on the other (people and the state). On the side of the, opposing force, only one thing unified them, the defense of their creed (defense of the millat). At this time, there was a radical

Microprocessor and Interfacing Essay Example for Free

Microprocessor and Interfacing Essay Peripherals and Interfacing PIO 8255 The parallel input-output port chip 8255 is also called as programmable peripheral input-output port. The Intel’s 8255 is designed for use with Intel’s 8-bit, 16-bit and higher capability microprocessors. It has 24 input/output lines which may be individually programmed in two groups of twelve lines each, or three groups of eight lines. The two groups of I/O pins are named as Group A and Group B. Each of these two groups contains a subgroup of eight I/O lines called as 8-bit port and another subgroup of four lines or a 4-bit port. Thus Group A contains an 8-bit port A along with a 4-bit port. C upper. PIO 8255 †¢ The port A lines are identified by symbols PA0-PA7 while the port C lines are identified as PC4-PC7. Similarly, GroupB contains an 8-bit port B, containing lines PB0-PB7 and 4-bit port C with lower bits PC0- PC3. The port C upper and port C lower can be used in combination as an 8-bitport C. †¢ Both the port C are assigned the same address. Thus one may have either three 8-bit I/O ports or two 8-bit and two 4-bit ports from 8255. All of these ports can function independently either as input or as output ports. This can be achieved by programming the bits of an internal register of 8255 called as control word register ( CWR ). PIO 8255 †¢ The internal block diagram and the pin configuration of 8255 are shown in fig. †¢ The 8-bit data bus buffer is controlled by the read/write control logic. The read/write control logic manages all of the internal and external transfers of both data and control words. †¢ RD, WR, A1, A0 and RESET are the inputs provided by the microprocessor to the READ/ WRITE control logic of 8255.

Modes of Operation of 8255 (cont.. ) †¢ The control signals for both the groups in input and output modes are explained as follows: Input control signal definitions (mode 1 ): †¢ STB( Strobe input ) If this lines falls to logic low level, the data available at 8-bit input port is loaded into input latches. †¢ IBF ( Input buffer full ) If this signal rises to logic 1, it indicates that data has been loaded into latches, i. e. it works as an acknowledgement. IBF is set by a low on STB and is reset by the rising edge of RD input. Modes of Operation of 8255 (cont.. ) †¢ INTR ( Interrupt request ) This active high output signal can be used to interrupt the CPU whenever an input device requests the service. INTR is set by a high STB pin and a high at IBF pin. INTE is an internal flag that can be controlled by the bit set/reset mode of either PC4 (INTEA) or PC2(INTEB) as shown in fig. †¢ INTR is reset by a falling edge of RD input. Thus an external input device can be request the service of the processor by putting the data on the bus and sending the strobe signal. Modes of Operation of 8255 (cont.. Output control signal definitions (mode 1) : †¢ OBF (Output buffer full ) This status signal, whenever falls to low, indicates that CPU has written data to the specified output port. The OBF flip-flop will be set by a rising edge of WR signal and reset by a low going edge at the ACK input. †¢ ACK ( Acknowledge input ) ACK signal acts as an acknowledgement to be given by an output device. ACK sig nal, whenever low, informs the CPU that the data transferred by the CPU to the output device through the port is received by the output device. Modes of Operation of 8255 (cont.. ) †¢ INTR ( Interrupt request ) Thus an output signal that can be used to interrupt the CPU when an output device acknowledges the data received from the CPU. INTR is set when ACK, OBF and INTE are 1. It is reset by a falling edge on WR input. The INTEA and INTEB flags are controlled by the bit set-reset mode of PC 6and PC2 respectively. 1 0 1 0 Input control signal definitions in Mode 1 1/0 X X X 1 X X X X 1 1 X D7 D6 D5 D4 D3 D2 D1 D0 1 Input 0 Output For PC6 PC7 PA0 PA7 INTEA PC4 PC5 STBA IBFA D7 D6 D5 D4 D3 D2 D1 D0 PB0 PB7 INTEB PC 2 PC1 STBB IBFB PC3 RD PC6 PC7 INTRA I/O PC0 INTR A Mode 1 Control Word Group A I/P RD Mode 1 Control Word Group B I/P STB IBF INTR RD DATA from Peripheral Mode 1 Strobed Input Data Transfer WR OBF INTR ACK Data OP to Port Mode 1 Strobed Data Output Output control signal definitions Mode 1 1 0 1 0 1/0 X X X 1 X X X X 1 0 X D7 D6 D5 D4 D3 D2 D1 D0 1 Input 0 Output For PC4 PC5 PA0 PA7 INTEA PC7 PC6 OBF ACKA D7 D6 D5 D4 D3 D2 D1 D0 PB0 PB7 INTEB PC PC2 1 OBFB ACKB PC3 WR PC4 PC5 PC0 INTRA I/O INTRB Mode 1 Control Word Group A Mode 1 Control Word Group B Modes of Operation of 8255 (cont.. ) †¢ Mode 2 ( Strobed bidirectional I/O ): This mode of operation of 8255 is also called as strobed bidirectional I/O. This mode of operation provides 8255 with an additional features for communicating with a peripheral device on an 8-bit data bus. Handshaking signals are provided to maintain proper data flow and synchronization between the data transmitter and receiver. The interrupt generation and other functions are similar to mode 1. †¢ In this mode, 8255 is a bidirectional 8-bit port with handshake signals. The RD and WR signals decide whether the 8255 is going to operate as an input port or output port. Modes of Operation of 8255 (cont.. ) †¢ 1. 2. 3. 4. 5. The Salient features of Mode 2 of 8255 are listed as follows: The single 8-bit port in group A is available. The 8-bit port is bidirectional and additionally a 5-bit control port is available. Three I/O lines are available at port C. ( PC2 PC0 ) Inputs and outputs are both latched. The 5-bit control port C (PC3-PC7) is used for generating / accepting handshake signals for the 8-bit data transfer on port A. Modes of Operation of 8255 (cont.. ) †¢ Control signal definitions in mode 2: †¢ INTR (Interrupt request) As in mode 1, this control signal is active high and is used to interrupt the microprocessor to ask for transfer of the next data byte to/from it. This signal is used for input ( read ) as well as output ( write ) operations. †¢ Control Signals for Output operations: †¢ OBF ( Output buffer full ) This signal, when falls to low level, indicates that the CPU has written data to port A. Modes of Operation of 8255 (cont.. ) ACK ( Acknowledge ) This control input, when falls to logic low level, acknowledges that the previous data byte is received by the destination and next byte may be sent by the processor. This signal enables the internal tristate buffers to send the next data byte on port A. †¢ INTE1 ( A flag associated with OBF ) This can be controlled by bit set/reset mode with PC6 . †¢ Control signals for input operations : †¢ STB (Strobe inp ut ) A low on this line is used to strobe in the data into the input latches of 8255. Modes of Operation of 8255 (cont.. ) †¢ IBF ( Input buffer full ) When the data is loaded into input buffer, this ignal rises to logic ‘1’. This can be used as an acknowledge that the data has been received by the receiver. †¢ The waveforms in fig show the operation in Mode 2 for output as well as input port. †¢ Note: WR must occur before ACK and STB must be activated before RD.

(P4) [Learner needs to design a LAN on the paper for their LAN selection.] last.jpg Identify the various parts (software and hardware) of a network system for Smith Solicitor and relates it to the 7- layered model. (P5) The various parts of a network system for smith solicitor which is related with 7 layeres model are Physical Layer:  This layer explains the physical properties of the various communications media and coordinates the function required to transmit Example: It explains the size of Ethernet coaxial cable, layout of pins. The physical layer uses hubs and repeaters. Data Link Layer: This layer explains the logical organization of data bits transmitted on a particular medium. Example: this layer gives addressing and checks summing of Ethernet packets. Network Layer: This layer helps to describe the exchanges of packets between any two nodes in a network. Ex: It defines the addressing and routing structure of the Internet. Transport Layer: In transport layer it describes the class, quality and type of the data delivered. This layer makes sure if and how retransmissions will be used to ensure data delivery.   Session Layer:   In this layer the group of data sequences larger than the packets handled by lower layers. So it is handles synchronization process. Example: It shows the details of request and reply packets are paired in a remote procedure call.   Presentation Layer: This layer works to translate, encrypt and compress data. Ex: this layer describes how floating point numbers can be exchanged within hosts with different math formats Application Layer: This layer gives services to the user by allowing the access to network resources Ex: this layer would implement file system operations Differentiate between different kinds of network, network topologies and network operating systems. (P6) [Discuss different network topologies] The different kinds of network are A  local area network also knows as LAN  is a kind of network where the networked computers are in short distance only. Example a network within a building of school. LANs Usually owned, controlled, and managed by a single person or organization. They use Token ring or Ethernet technology Metropolitan area network also known as MAN is a network spanning a physical area larger than a LAN but smaller than a WAN, such as a city. Example it is commonly owned by a single body like as a government body or large company. Wide area network also known as WAN is a geographically single collection of LANs. It generally covers wide area of computer networks. A router connects different LAN to WAN. For example- mostly WANs (like the Internet) arent owned by any organization or group but it works under the joint or distributive ownership and management. The different types of network topologies are: Star topology and tree topology All devices connect to a central device, called hub. All data transferred from one computer to another passes through hub Popular in LAN because its inexpensive and easy to install. Whereas tree topology is the extended form of star topology which is used in large networks .This kind of network significally reduces the traffic on wires by sending packets only to the wires of the destination host Ring topology In this kind of topology cables are formed in closed ring or a loop form where the devices are arranged along the ring. Data communication is d one in this topology by device to device around entire ring in one direction only but if we use dual ring then communication can be done by both direction Mainly this topology is used in LAN network but it is also used in WAN network. Mesh topology In this kind of topology all computer are connected to each other so that theres a fault tolerance in this kind of topology. It is expensive as well as difficult to create this type of topology. Here all the nodes are connected to each other and forms complete network. This kind of network topology is mostly use in financial sector. 3.1 Set up a software network environment, for some departments in a Smith Solicitor organization. (P7) [Configure Active directory] To configure an active directory for smith solicitor organization following process in taken. Click start and type dcpromo and enter. Then a dialogue box will appear. Then we need to press next. After that we will see a domain control type wizard where we need to select the domain controller for a new domain and select next option. Then we need to select the domain in new forest and press next as show in picture below. 4.png After that on the  New Domain Name  page, in the  Full DNS name for new domain  box, we need to give some domain name .For example we can give domain name like SmithSolicitiorFirm.com. After that we need to give name for NetBIOS domain name and click next where we get to seelect the location where we would like to store and save the database and log files. On the  Shared System Volume  page, accept the default in the  Folder location  box, and then click  next. On the  DNS Registration Diagnostics  page, click  Install and configure the DNS server on this computer and set this computer to use this DNS server as its preferred DNS Server, and then click  next as shown in the picture below.

After that on the  Directory Services Restore Mode Administrator Password  page, we need to enter a password in the  Restore Mode Password  box and again retype the password to confirm it in the  Confirm password  box, and then click  next. Finally in last we just need to confirm that the given information are correct and click next  and When prompted to restart the computer, click  Restart now. This is the successful configuration of active directory for smith solicitors server computer. 3.2 Install a piece of network software on to a server to be used by different selected users in a created group on Smith Solicitor Network.(P8) [configure print server] We can configure a print server in smith solicitor network by the following process given below. Installation process: Firstly connect the printer to the computer .Then the printer will be detected automatically. After that we need to install driver which we normally get with printer. Else we can do it manually by the following process as shown below. Click on Start > Settings > Control Panel > Printer and Faxes. Then Click on the File Menu > Add printer > Next > Local Printer attached to this computer.  After that it Checks automatically detect and Install My Plug and Play Printer. Then Click Next. After that a wizard will automatically detect any attached printer and install the driver for it. If the system doesnt find the driver then it will be prompted to provide the drivers location. After successfully installing the printer driver, it will show new printer name in the Printer and Faxes in the control panel. Server Configurations: If the printer needs to be shared by a server computer, firstly we need to click the printer name>properties>sharing>share this printer. Then we need to provide name for the shared printer which will be used by client computer on the network. We can also set the colour management, priorities, printing preferences, font s in the properties tab of the printer. Client Computer Configuration: To setup printer at the client computer we can just give the command \computernameprintername (printer name is the shared name of the printer which we create while configuring server) 3.3 Illustrate how you configure user workstations on the network? (P9) [Steps of user configuration on Active directory] To configure user workstation on the network firstly we need to have one active directory domain, where we need to create a user account in that domain to use as an administrator account. Then after adding the user to the exact security group we can use that account to add computer to domain. To configure user on active directory following process should be completed. C:UsersjaikishanshresthaDesktopAdd new user in Exchange 2003.PNG Firstly click start and then point the cursor towards administrator Tool. Then Click Active Directory Users and Computers  to start the Active Directory Users and Computers console. After that we need to click the domain name that had been created, and then expand the contents. Where we need to right- click Users>New>User Type the first name, last name, and user logon name of the new user, and then click  Next. Where we get other wizard to type a password and confirm it by typing again and click the check box as required by user. Then click Next .After that just check the details and enter to Finish. Finally a new user will be created under the active directory. In case of adding a computer to the domain, following the steps Log on to the computer that needs to be added to the domain. Then right click on MY Computer>Properties>Computer Name Tab>Click change. In the computer Name change dialogue box, click Domain under member of and type the domain name. After that click OK.When you are prompted, type the user name and password of the account that you previously created, and then click  OK. Then a welcome message appears in a dialogue box where we need to click OK and restart. 4.1 Write a report on the rights and responsibilities of the network manager and the network user for Smith Solicitor (P10) [Discuss role of Network admin- user rights, sharing etc. and network user password, maintain file etc.] Network administrator need to setup and configure all the devices, hardware, software, connection between the computers. They should be able to add the user and delete the user as the requirement of the company or manage the password and access control as the requirement and ensure that there is a proper security in the network to protect it from hackers and viruses. They are deeply involved in making sure that the software are updated and applications, and monitoring the performance of the network, checking for security breaches, poor data management practices and more. So scheduled check up should be done. Administrator should be able to manage user account such as file access privileges and passwords. Administrator should also train user to utilize the networks resources and also train users to work under the server network environment. Administrators keep records of all users problems and errors as well as the steps taken to solve the problems. This information is used to help solve future problems. Administrators also control user access to the network. The administrator must also create a firewall-a set of security measures designed to make sure that no one can gain unauthorized access to the system. Administrator should use Active directory for centralized management and manage user environment. Admin should respond to the needs and question of clients concerning their access to resources and create backup in different ways to recover any lost data. They are responsible to manage, assign and maintain the list of network addresses. 4.2 Apply control mechanisms in a Smith Solicitor network for managing users. (P11) [Discuss group policy, user authentication, authorization etc.] Control in a smith solicitor network for managing users can be done by using centralized management system in active directory. Active Directory enables the administrator to centrally manage resources and to easily find the information location. It also enables to group the users according to the users limitation because user group policy helps to makes different policy for the user by the administrator. Active directory user authorization secures resources from the unauthorized user and unauthorized access. Managing Authorization and Access Control Published: November 03, 2005 The Microsoft Windows XP Professional operating system includes a number of features that you can use to protect selected files, applications, and other resources from unauthorized use. These features, which include access control lists, security groups, and Group Policy, along with the tools that allow you to configure and manage these features, provide a powerful yet flexible access control infrastructure for your local resources and network. Understanding what these features are, why they are necessary, and how they function will help you to manage rights and permissions on network and local resources more effectively. Security principal In Windows XP Professional, any entity that can be authenticated. A user, group, computer, or service can be a security principal. Security principals have accounts. Local accounts are managed by the Local Security Accounts Manager (SAM) on the computer. If the account is in a Microsoft Windows 2000 or Windows Serverà ¢Ã¢â‚¬Å¾Ã‚ ¢ 2003 domain, it is managed by Active Directory. If the account is in a Microsoft Windows NT version 4.0 domain, it is managed by a SAM database on the primary domain controller. Inheritance A mechanism for propagating access control information down through a tree of objects. In Microsoft Windows NT, an object (such as a file) inherits access control information from its parent object (such as a folder) only when the object is first created. In Windows XP Professional, objects inherit access control information not only when they are created, but also when the parent objects access control list changes. Owner The only security principal who has an inherent right to allow or deny permission to access an object. An objects owner can give another security principal permission to take ownership. By default, the built-in Administrators group on a computer is assigned a user right that allows this group to take ownership of all objects on the computer. Security groups Groups that can be used to organize users and domain objects, thus simplifying administration. Security groups allow you to assign the same security permissions to a large numbers of users, such as employees in a single department or in a single location, ensuring that security permissions are consistent across all members of a group. Security descriptor A data structure containing the security information associated with a securable object. A security descriptor identifies an objects owner by SID. If permissions are configured for the object, its security descriptor contains a discretionary access control list (DACL) with SIDs for the users and groups that are allowed or denied access. If auditing is configured for the object, its security descriptor also contains a system access control list (SACL) that controls how the security subsystem audits attempts to access the object. Access control list (ACL) An ordered list of access control entries (ACEs) that define the permissions that apply to an object and its properties. Each ACE identifies a security principal and specifies a set of access rights allowed, denied, or audited for that security principal. Security settings Security configuration settings that can be applied to individual computers. These settings can be configured locally on the computer by using the Local Security Policy administration tool, the Microsoft Management Console (MMC) Security Configuration and Analysis snap-in, or, if the computer is a member of an Active Directory domain, through the Security Settings extension to Group Policy. Auditing of system events You can use the auditing feature to detect attempts to circumvent protections on resources or to create an audit trail of administrative actions on the system. For example, you can audit failed attempts to open a file. You can also set security policy so that failed logon attempts are recorded in the security event log. If another administrator changes the auditing policy so that failed logon attempts are no longer audited, the log can record this event as well. In an Active Directory environment, you can use Group Policy to centrally control who is allowed to manage security logs on computers joined to a domain. user or group is stored as part of an ACE in a DACL that is part of the objects security descriptor. Rights and Permissions Access control involves the configuration of rights and permissions, which apply to both the objects on the local computer or network and the potential users (including individuals, computers, and services) of those objects. A  right  is authorization to perform an operation. From an administrators point of view, there are two types of rights: privileges and logon rights. In Windows XP Professional, only one user right is inherent-the right to allow or deny access to resources that you own. All other user rights must be granted, which means that they can also be withdrawn. A  permission  is authorization to perform an operation on a specific object, such as opening a file. Permissions are granted by owners. If you own an object, you can grant any user or security group permission to do whatever you are authorized to do with it. When permission to perform an operation is not explicitly granted, it is implicitly denied. For example, if Alice allows the Marketing group, and only the Marketing group, permission to read her file, users who are not members of the Marketing group are implicitly denied access. The operating system will not allow users who are not members of the Marketing group to read the file. Permissions can also be explicitly denied. For example, Alice might not want Bob to be able to read her file, even though he is a member of the Marketing group. She can exclude Bob by explicitly denying him permission to read the file. In fact, this is exactly how explicit denials are best used-to exclude a subset (such as Bob) from a larger group (such as Marketing) that has been given permission to do something. Each permission that an objects owner grants to a particular user or group is stored as part of an ACE in a DACL that is part of the objects security descriptor. User-Based Authorization Every application that a user starts runs in the security context of that user. When a user logs on, an access token is created. The access token contains key security-related information, including the users SID, the SIDs of the groups to which the user belongs, and other information about the users security context. This access token is then attached to every process that the user runs during that logon session. An application runs as a process with threads of execution. When an application performs an operation on a users behalf, one of the threads performs the operation. For example, when Alice opens a Word document, Microsoft Word, and not Alice, actually opens the file. More precisely, one of the threads of execution performs the operation. For a thread to gain access to an object such as a file, it must identify itself to the operating systems security subsystem. Threads and applications do not have a security identity, so they must borrow one from a security principal, such as Alice. When Alice starts an application, it runs as a process within her logon session. When one of the applications threads needs to open a file, the thread identifies itself as Alices agent by presenting her access token. Alice is therefore ultimately responsible for anything that the thread does to the file or system on her behalf. Before allowing the thread of execution to proceed, the operating system performs an access check to determine whether the security principal associated with the thread has the degree of access that the thread has requested. This access check involves the following steps: The security subsystem checks the file objects DACL, looking for ACEs that apply to the user and group SIDs referenced in the threads access token. If a DACL does not exist, access is granted. Otherwise, the security subsystem steps through the DACL until it finds any ACEs that either allow or deny access to the user or one of the users groups. If a deny is found at the user or group level, the access is denied. If the security subsystem comes to the end of the DACL and the threads desired access is still not explicitly allowed or denied, the security subsystem denies access to the object. Therefore, if a DACL exists but is empty, access is by definition denied. At the conclusion of this process, access is either allowed and the file is opened or access is denied, in which case the file remains closed and an Access Denied message is generated. Creating and deleting user accounts and defining and using security groups are important security tasks. Defining the security restrictions or permissions that might apply to different groups of users and resources in your network will help to simplify the implementation and management of the permissions and restrictions in your organization. For example, you can create a Printer Operators group and give it precisely delineated administrative control over a finite group of printers. For you to effectively manage security groups in your organization, you need to be familiar with the relationship between accounts, security groups, and built-in security principals. It is also important for you to become familiar with the techniques and tools available for managing group membership. Built-in security principals apply to any account that is using the computer in a specified way. Built-in security principals allow you to configure security based on the manner in which a resource is being accessed n increasing number of Windows XP Professional-based systems are connected directly to the Internet and participate in home or small business networks rather than in domains. To simplify the sharing and security model used in these nondomain environments, network logons performed against unjoined Windows XP Professional-based computers are automatically mapped to the Guest account by default. This simplifies the sharing of resources in home or small business networks by eliminating the need to synchronize user names and passwords across all computers in the network. Authenticating users logging on to the network as Guest can provide an additional measure of security for computers connected to the Internet by eliminating the ability to access the computer remotely by using administrative credentials. Forcing network logons to authenticate as Guest does not affect the following: Interactive logons. In addition to console logons, this also includes remote access sessions using Terminal Services or Telnet, which are essentially remote occurrences of interactive logon sessions. Computers that are joined to a domain. This is not the default for Windows XP Professional-based computers that are joined to a domain because the domain provides single sign-on capabilities for all computers that are in the domain.
