Encryption - How Sensitive Information Is Protected on the Internet :: Exploratory Essays Research Papers
Encryption - How Sensitive Information Is Protected on the Internet Have you ever visited a web site and seen something that you wanted to purchase? Were you apprehensive about making that purchase, because you were unsure of who would see your personal information? Well, for an e-business to be successful, the leaders of that business must take special security measures to protect their customerââ¬â¢s sensitive information. The most reliable method to protect sensitive information that is transmitted via the web, is encryption. Encryption is the coding and scrambling of messages to prevent any unauthorized access to data that is being transmitted. Applying a secret numerical code called an encryption key encrypts a message. This allows the message to be sent as a scrambled set of characters. If the message is to be unscrambled, it must be decrypted with a matching key. These keys consist of groups of letters, numbers, and symbols. If a website is secured by encryption, you will see a small lock on the lower right hand side of your screen on the status bar. There are two basic standards of encryption. They are, Secure Sockets Layer (SSL) and Secure Hypertext Transport Protocol (S-HTTP). Both of these allow the client and the server computers to manage encryption and decryption as they communicate with each other during a secure Internet session. Public key is a widely used type of encryption. However, there are several different types. This type of encryption uses two different keys. One key is private while the other key is public. First, a private and public key must be created. The private key, of course, is kept secret. The public key is kept in a directory. The sender sends a message with the receiverââ¬â¢s public key, and the receiver uses the private key to decrypt it. Another type of internet security device is called a digital signature. This is a digital code attached to a message that is electronically transmitted and used to identify the origins and contents of that message. The digital signature is then used by the receiver to verify that the message was not tampered with after being sent. A digital signature is similar to a real signature, in that it is a way to be sure that the person sending the message is indeed that person.

Anne Bradstreet: The Heretical Poet :: essays research papers fc
Anne Bradstreet: The Heretical Poet Greg Saxon The purpose of this research is to discuss heretical elements in the poetry of Anne Bradstreet (1612-1672). This is not to imply that Bradstreet was a heretic in the sense that American religious reformer Anne Hutchinson was. Hutchinson (1591-1643) emigrated to Boston in 1634 and preached a doctrine of salvation through intuitive apprehension of grace rather than by works, and attacked the rigid moral and legal codes of New England Puritanism. Anne Bradstreet accepted the tenets of Puritanism and was a very religious person. Anti-Puritan themes are, however, to be found in her poetry in terms of her religious doubts, her expression of personal emotions and thoughts, and her artistry. She did not write to preach or teach,, as Puritan writers were instructed to, but to express herself. It is this personal expression that forms the basis of the heretical elements in her poetry. To understand why personal expression may be considered heretical, the society in which Bradstreet lived and wrote must be examined in order to comprehend what kinds of human activities and behaviors were acceptable and how Bradstreet deviated from these behaviors. Bradstreet was not truly unorthodox in that she did not dissent from accepted beliefs and doctrine. She was a woman of the 17th Century and lived in a male dominated, intensely religious society. She lived within the limitations not only of the beliefs and standards of her society, but of her sex. A woman's place was definitely in the home in Colonial America. The experiences of women were considered narrow and trivial in comparison with men's. Puritanism was more than a religious belief; it was a way of life. "In the dozen years before 1640, some 15,000 Englishmen crossed the Atlantic in order to establish a 'Holy Commonwealth' in which that way of life could flourish"(Hall 1). The Puritans were a party in the Church of England that arose in Elizabeth's reign with the purpose of carrying out the Protestant reformation, and to base the Church of England on the foundation of the scriptures. Aside from a literal belief in the Bible, Puritans wholly accepted the doctrines of John Calvin and his stern legalistic theology. The Puritans held that religion should permeate every phase of living. The purpose of life was to do God's will; everything else was subordinate to this basic doctrine. The Colony set up by the English Puritans was essentially an experiment in Christian living. Religion and earning a living were the two priorities of the Puritans of the Massachusetts Bay Colony. In contrast to the Pilgrims, they were well-off and well-educated men, many of whom were professionals and

High school statistics as a basis for increased beginner learning Essay
Although not the primary focus of this study, it is important to understand the future of elementary students by looking into current graduates predicaments. Over the last twenty years, there have been dramatic increases in high school promotion; as well as, in graduation requirements. Most recently, states and districts, such as Mississippi, have begun implementing graduation and end-of-course exams (Committee for Economic Development, 2000). Some critics have noted that the rise in standards and high-stakes tests will be unfair to students who have attended poorly resourced schools (Achieve, 2000). However, this problem has been met by offering extra help and supportive services to the students of the disadvantaged schools (2001). One of the most common support methods has been to offer disadvantaged students more time; such as summer school, adding an extra year to their high school education and transition programs to ensure students can fulfill high school requirements (2001). Little progress has been made in developing a better curriculum and instructional support to aid in the acceleration of learning for disadvantaged high school (Balfanz, et al. , 2002). Some high schools have implemented a whole school reform by creating catch-up courses and district wide special prep courses (2002). These reforms have not been thoroughly evaluated because their infancy; using small, formative studies, thus little is known about the feasibility and rapidity of student acceleration in disadvantaged high schools. This study aims at taking the first step to in understanding the elementary school learning needs and providing appropriate teaching techniques for each schools situation; by reporting on the initial results and impacts of the Talent Development High Schools (TDHS) ninth grade instructional program in reading and mathematics. The study involves several cities and multiple high-poverty, non-selective high schools within each city. Academic Models of Recognition Piney Woods School in Piney Woods, Mississippi has programs that should be viewed as national models. Although a private school, its strategies for success are practical and successful. The predominantly African American school is known for changing the lives of low-income students by having them ââ¬Å"complete a rigid diet of reading, writing, math, science and foreign languageâ⬠(Wooster, et al. 2001). While requiring students work ten hours a week in order to teach them responsibility, Piney Woods School gives students a sense of unity and tough love. The programs implemented are; Writing Across the Curriculum, which trains freshman and sophomoresââ¬â¢ in basic composition skills; Always Reaching Upward, a peer tutoring program which pairs under achievers with high achievers and Save the Males, a tutoring, mentoring and special male focused groups that facilitate responsibility and self confidence. The results are phenomenal with a ninety five percentage rate of students going on to college after graduation and the other five percent going into military services. Analysis of existing achievement data in high-poverty high schools provides two conclusions. First, students who attend high-poverty high schools are typically performing below national norms and are dramatically short of the performance benchmarks employed to measure academic success. An analysis conducted by Education Week (1998) indicates, for example, that students entering high school in the majority of large cities are often found to be two or more years below grade level (Quality Counts ââ¬â¢98, 1998). In Philadelphia, for instance, seventeen percent of high school students attend one of twenty-two non-selective neighborhood schools (Neild & Balfanz, 2001); and approximately half of these students are reading below the fifth or sixth grade level. A quarter of these students are reading at the seventh or eighth grade level. Approximately one in four students attending a nonselective high school in Philadelphia read at grade level. In eight of the non-selective neighborhood schools in Philadelphia, a little over two thirds of first-time ninth graders are performing below the seventh grade level in both reading and mathematics (Neild & Balfanz, 2001). One important conclusion that can be drawn from this data is that in many non-selective urban schools students need accelerated learning opportunities. A second conclusion is that the current level of academic performance in disadvantaged high schools can lead to multiple negative consequences for students and society. It is too early to accurately gauge the impact of the high-stakes; standards based graduation tests and dropout rates of students entering high school with weak academic skills (Bishop & Mane, 2000; Hauser, 2001). Existing data from metropolitan cities such as Chicago (Roderick & Camburn, 1999) and Philadelphia, however, demonstrates a link between poor academic preparation and course failure; as well as the retention of many high-poverty students. Course failure and retention in the ninth grade has caused a high amount of high school drop outs. Forty-three percent of first-time freshmen in Philadelphia entering ninth grade with below seventh grade math and reading skills were not promoted to the tenth grade (Neild & Balfanz, 2001); in comparison to the eighteen percent of students entering ninth grade with math and reading skills above the seventh grade level. Student skills below grade level requirements result in retention, poor attendance, and course failure. First-time freshmen who were not promoted to the tenth grade had a dropout rate of nearly sixty percent when compared to a twelve percent drop out rate for students who were promoted (Neild, Stoner-Eby, & Furstenberg, 2001). The individual and social consequences of dropping out of high school are considerable. The Committee for Economic Development (2000) has documented the economic returns to advanced education. Non-promotion has become the norm in approximately two hundred-fifty to three hundred high schools, in thirty-five major cities in the United States (Balfanz & Legters, 2001). Sixty percent of the population in these public high schools is African American and Latino students in (2001). The United States Department of Education expresses the importance of raising graduation requirements and standards; therefore it is essential to the success of future high school students, that a means of improving reading proficiency is achieved.

An Overview of Altruism from Darwin to the Present
Altruism itself is considered a virtue in todayââ¬â¢s society and is present in many religions, humanitarian and philanthropic causes. This selfless concern for others of helping behaviour is not something that is only found in humans but can be found in most species and is actually a type of behaviour that has evolved with species. Though Charles Darwin first made note of com/common-core-ela-9-2014-ela3009-a-ic/">altruistic behaviour in his seminal work, The Descent of Man, the actually theory of altruism was not recognized until the early 1900s (Darwin, 1871, Kropotkin, 1902).Altruistic behaviour is difficult to understand and its evolution has proven to be interesting as the reason for behavioural changes cannot completely be defined. Additionally pure altruism is rarely found in nature, as those noble animals tend to die before they can pass down their genetic traits. Though Darwin did not completely understand altruism his work, the Descent of Man, is one of the first scienti fic published works that describes altruistic behaviour.His observation of animals helping others actually opposes his evolutionary theory of the survival of the fittest because in order for an individual to survive they need to take care of themselves and not sacrifice for others. According to natural selection theory, benevolent behavior should not evolve because it, technically, costs or even harms the doerââ¬â¢s fitness. Darwin did attempt to explain this phenomena by including it in group selection, as in order for groups to survive natural selection may actually favour groups of individuals and in this case the altruistic behaviours would be passed down to the next generation.(Darwin, 1871). This phenomenon of cooperation was not completely described until Kropotkin published a book, a collection of essays, dealing with mutual aid (Kropotkin, 1902). This work was a direct response to social Darwinism. Kropotkin was able to build a more satisfactory tie to individual natural selection and cooperation, displaying that mutual aid selection directly benefits individuals own struggle for personal success, so that cooperation between species will actually be the best path for individual success (mutual aid, 1955).Altruistic behaviour has since been researched and discussed by many scientists since its recognition in evolutionary biology. Scientists have thought that altruistic behaviour may be instinctual and that helping behaviour survives because it makes the individual feel good, particularly in humans (Wilkinson, 1988). There is also the theory that if an animal helps another then they may have the favour repaid back in the future, which can be found in human society (Kreb, 1952).Much research delving into altruistic behaviour and evolutionary biology cannot find a firm fit for altruism in general evolutionary terms. Inclusive selection or kin selection, in which species display behaviour that selections for those in their family to reproduce, cannot co mpletely explain altruism as it does not attempt to explain why differing species help each other (Hamilton, 1964). Symbiotic relationships, in which both species benefit, are based on specific conditions such as long-lives, dependence for food, performing a necessary service etc.(Trivers, 1971). In symbiotic relationships the help is eventually repaid by the species even if it takes a long time as the species my loss a little fitness at the current time but in the end the long term benefit will far outweigh any previous problems or disadvantages, known as reciprocal altruism. Much work has been done to investigate reciprocal altruism and inclusive fitness, particularly as evolutionary biology has evolved to include theories such as the game theory and predictive behaviour.Game theory points out that reciprocal altruism can also include negative behaviour, such as a cheater can expect to be punished in the future for its behaviour to others. (Trivers, 1971) It has been argued that t hese two types of behaviour, inclusive selection and reciprocal altruism are not truly altruism, as with altruism the species providing help does not get anything in return; much of research is devoted to study these evolutionary ideas (Rothstein and Pierotti, 1980). In the 1980s altruistic behaviour began to be investigated in Primates particularly with grooming behaviour.Primatologists noted that an individualââ¬â¢s status in a hierarchy seemed to be related to their relationships with others. Aiding dominant members seemed to be favoured. Juveniles needed to ingratiate themselves in the group and aiding a dominant female is a means of securing status in the hierarchical society of bonobos. (de Waal, 1989) Certain primates will chose to groom other primates and later they will gain some sort of benefit. A more recent study has shown a different aspect of reciprocal altruism as dominant female primates were found to groom subordinate primates, a type of grooming-down which had n ot been observed yet (Parr, et al.1995). Current altruism research is based around game theory and includes behavioural manipulation, bounded rationality, conscience, kin selection, memes, mutual aid, selective investment theory, sexual selection, reciprocity, and pseudo-reciprocity. The Price equation was developed to redefine Hamiltonââ¬â¢s work on kin selection and describes natural selection and evolution. In this mathematical equation altruism is defined as a behavioural genetic predisposition that increases the fitness of the group which in turn causes the individual that belongs to that group to benefit.(Frank, 1997). A fantastic example of this is with slime mould. Slime mould live as individuals until they are starving when the aggregate and form a multicellular organism and some cells sacrifice themselves for the benefit of the group. Altruism in humans has begun to be investigated and shown that specific regions of the brain will trigger charitable or helping behaviour . It was found that altruism does not suppress selfishness but actually very basic to brain function and triggers a pleasurable response (Moll and Grafman, 2006).The theory of group selection has re-emerged when looking at aboriginal lifestyle in Africa. Individuals of groups were found to be more closely related then previously believe suggesting that the nicest really do survive. Those that shared food and other goods would reproduce and pass on their genes as individuals would ban together during difficult times (Fischer, 2006). Interestingly it is through religion that altruism is spread throughout the human population. Buddhism, Judaism, Sikhism, Christianity, Islam and Hinduism all place particular importance on altruism.There are many individuals that oppose altruism saying that it is a morality, more of an ethics branch than evolution, as individuals do not need to be altruistic to survive. Though as social beings an altruistic natural may make you more social it will not ul timately cause your death or the inability to pass on your genetics. Most of the controversy with altruism today revolves around the factor that altruism may not apply to humans, though humans do have symbiotic relationships with other species, (think of the bacteria in your digestive tract).There is a split between real altruism and psychological altruism though most will agree that those individuals that care for others, such as parents for their children will be able to survive in society much easier than those that do not care for anyone. Most of altruism in humans is psychological and not due to a selfish gene. Also due to advances in technology ands science natural selection has taken a bit of a turn or slowed down so understanding altruism in humans is possible quite different then observing altruism in other species.

Athletics In MacGregors Sporting Landscape
However, using tactics which corroborate teamwork and competitive factors which in theory will motivate students to strive and increase their participation levels. 1. 0 Introduction This report will provide a detailed analysis of the participation of athletics in Macgregorââ¬â¢s microcosm as the societal norm believe that the status quo is ââ¬Å"uncoolâ⬠, it is known that the position of Australiaââ¬â¢s porting landscape is very weak as there is a lack of participation within Australia as a whole This can be answered by a simple formula created to find the reason why some sports have a lack in participation in mainstream society today, Figueroaââ¬â¢s framework, this formula is divided into Levels listed in the following Cultural, Structural, Institutional, interpersonal and individual levels, nonetheless, it Is concluded that it is up to the individual of whether they decide to participate in Athletics or not. 2. 0 Figueroaââ¬â¢s Framework The social factors that influence an individualââ¬â¢s decision to participate in Athletics may indirectly or directly impact them by shaping their values, attitudes and beliefs. Knowing this the individual may find themselves being subjective to the people and also the certain factors they face in society ranging from cultural differences to peers to themselves. Sociologist, Peter Figueroa, develop a framework that analyses the equity of social resources that can also be implemented into the participation of athletics. . 1 Individual Level It can be argued that when it comes to equity and access issues, the individual level is the most important. This is because, while all levels of Figueroaââ¬â¢s Framework can identify how equity and sporting opportunities are presented to an individual, in the end it is the individualââ¬â¢s choice that will determine his or her access and level of participation in physical education. Kiss, 2012) This level is specific to Macgregorââ¬â¢s sporting landscape as it highlights the lack of participation in students; nonetheless, these decisions about sport and physical activity are ultimately made by the individuals Gen es, values, attitudes and personalities which are specific to each individual. 3. 0 Action plan In Macgregorââ¬â¢s deteriorating athletics program, the lack of participation in the carnivals can link to many reasons why they donââ¬â¢t compete in such events. Study shows that the majority of students would prefer to sit and chat with their friends instead of competing in athletics, however, to allow students to participate, an action plan was developed to; in theory create a more fun and enjoyable carnival thus increasing participation levels, using successful methods utilized in Australian sports such as Cricket, NRL, AFL, etc. The ideologies used within these sports can be integrated within the society of Macgregorââ¬â¢s microcosm shaping the status quo of Macgregorââ¬â¢s Athletics program in a more positive, enjoyable way. . 1 Justification of Action plan Throughout sporting history there are various techniques to strive for in order to have a successful carnival, the majority of successful sports share many similar techniques to better improve the participation of athletes in Australia such as making it more interactive for the audience thus improving their participation rates; for example, in tennis they implement a board that measures the speed of the serve for each game as well as the Olympics which show the world record for each event. nowing this; a supposed board that lists all the records of each event is shown publically pre-athletics carnival and during for students to observe and in theory become more motivated and strive to train and compete in the events believing they are able to break that record thus improving participation rates. Secondly, the appearance of famous sporting athletes have known to improve the participation of sports for example, NBA players frequently appear in many occasions of street basketball games as it obviously creates publicity, however, also improves the participation due to the fact that this allows the ââ¬Ëaverage basketball fanaticââ¬â¢ who normally would watch their idol from the comfort of their own television, but in fact they are able to play side by side with their idol increasing their moral and motivation to play. This can also be implemented in the athletics carnival by having the famous athlete participate and motivate the students to join in and also create a slight sense of competition. Finally, it is a fact that Australians love to play team based sports as listed, AFL, Cricket, Football, NRL, Soccer, Basketball, Rugby League are in the top 10 Australian sports; this is 7 of the 10 sports that are shown. With this in mind, Students would be required to form groups of 3 and compete in the athletics carnival, with a twist; each event would hold a certain amount of points varying on the position the student places, 10points for 1st, 7points for 2nd, 5point for 3rd and participation will be worth 2 points. The team that scores the highest points will be rewarded with a prize, such as vouchers, etc. 4. 2 Links to survey results The action plan created was based on a census of the whole school to observe whether they would participate in athletics and their reasons to not. To justify the particular choices created in the action plan by showing the statistics which have guided the development as the spikes in the statistics assist in improving the participation by surveying the trend. The reason a record chart was implemented as it adds a competitive flair and students receive social rewards within the athletics carnival as 19% of students feel that there is no reward for students if they win the events, this will help students strive for the record instead of just trying to win. A massive 27% of students feel that they are not good enough for the athletics carnival and believe there is no point to participate and simply just socialize with their peers, with the appearance of a famous athlete; students would be motivated to part take in the events as the special guest can provide moral support and advice to improve their technique, etc. during the carnival as they can join in with the students. By creating team based events the 80% of students that prefer team sports are able to participate and at the same time fill the social void according to the 25% as they strive to motivate fellow teammates and allow each other perform better overall, also considering the 66% that would participate in the carnival if their peers were to join in. (Buckley, et al, 2013) 4. Links to research material including the individual level of the framework The research gathered of Figueroaââ¬â¢s framework on the individual level, it is realised that students values and beliefs are to strive for competition and rewards, as these factors have been fulfilled it will allow students to participate in a more enjoyable way, due to the fact that an individualââ¬â¢s values and beliefs reflect directly upon their parents, siblings and peers, however, it is proven that the individual learns to behave through the experience they have accumulated from mainly their peers, also the fact that students view the sports society in a ââ¬Ëboringââ¬â¢ manner, they often assume they cannot socialise with their peers which majorly affect their participation rates. 5. 0 Conclusion

My leader Assignment Example | Topics and Well Written Essays - 250 words
My leader - Assignment Example It turned out that the reporting sessions or the reports were deleted from the accounts by the supervisor by mistake. It had a record of more than one month of reporting of the security checks. It was a great loss of information. On the date of the audit, the supervisor came himself to check on the reports since there was no information delivered. Firstly, it was astonishing that the regional head would visit the workplace to inquire about reporting. As soon as he was informed about the mishap of loss of information, he took a proactive approach rather than becoming angry. He took control of the situation and rather asked the sub-parameter or computers from where the reports were being sent. Instead of becoming overly concerned about the mishap, the regional head took notice of the situation and found out alternative ways. He could have simply misreported the progress of the supervisor for his personal interest but he rather becomes a team leader than just being the

IBM in China Essay Example | Topics and Well Written Essays - 750 words
IBM in China - Essay Example However, the process of manufacture of many of these parts contribute to pollution since they use CFCs and require high levels of power and cooling at datacenters, all of which have exacerbated greenhouse gas emissions and Chinaââ¬â¢s increased energy use. China is a country where three decades of a communist regime have been followed by 25 years of ââ¬Å"quasi-capitalismâ⬠, creating unrestrained economic and industrial growth and development, which have contributed heavily to pollution ââ¬â China consumes 14.2% of the worldââ¬â¢s energy and 70% of its rivers and lakes are heavily polluted. Some experts have contended that globalization impacts adversely upon the environment, since countries are forced to lower their production costs by neglecting to enact laws to preserve the environment and multinationals have the tendency to locate their polluting facilities in countries where environmental controls may be lax. In China, State environmental protection agencies are understaffed and are not equipped to cope with the burgeoning pollution levels in the country. Latest trends in China indicate that there is a growing antipathy in China against foreign investors, since it is the prevailing opinion that foreign investors use inexpensive Chinese labor and excessive amounts of energy to pollute the environment, then condemn the country for pollution and for producing cheap goods. Within China, IBM has recently been purchased by a Chinese Company Lenovo and with growing levels of fair competition within China, privatization is being encouraged. The switch to Lenovo could help IBM to tackle the stiff competition it is facing from other companies like dell and HP in the Asian region.
