Psychology and Motivation Essay
What are some of the limitations of traditional approaches to motivation? Discuss this question, referring to at least three specific management theories and considering the historical context in which these ideas were developed or adopted. Motivation in general refers to the result of behavioral changes in reaction to internal or external stimuli. Analysis can be done at the individual psychological level too. The studies attempt to understand peopleââ¬â¢s behaviour and come up with general conclusions from individual cases. (Encyclopedia Britannica, 2009) Some classified motivation as either a product or a process (Winne & Marx, 1989). In viewpoint as a product, motivation refers to willingness, desire, or condition of stimulation. On the other hand, it can also be known as the cognitive and affective processes where level of motivation or goal-directed behaviour is determined (Pintrich & Schunk, 2002). From this viewpoint, motivation refers not just to an end state, but also to the cognitive processes that control how the end state is achieved (Winne & Marx, 1989). This perceptive contradicts with the hypothesis to which one relates motivation with achievement or performance (Alexander & Winne, 2006). Numerous theories have been made on motivation. Some of the traditional approaches from most quoted theorists would be the classic theory from Frederick W. Taylor and the traditional motive approach pioneered by Henry Murray. Taylor advocated the theory that people will be extremely motivated if their reward is tied directly to performance. It creates assumption that one would choose the path that is most financially profitable and that money is the best motivation. Studies have shown that financial opportunity can definitely result in improvements especially in jobs with lower socio-economic rankings. It cannot be denied that money can motivate most people, but many have risen above it. Example would be religious missionaries, whereby they renounced financial security for greater spiritual satisfaction (Lorenzana, 1993). Murrayââ¬â¢s work contributed most to the roots of the achievement motive tradition. Summarizing from his classic work, Explorations in Personality, he uses the concept of need, to explain motivation in two district senses. First, whenà one is in a state of need, fulfilling end situations usually come to mind, resulting in one experiencing a sense of desire or wish. Desire will lead to intention and purpose and subsequently to strivings. Whereas the bulk of Murrayââ¬â¢s theoretical attention focused on needs as motivational processes, he also used the term need to describe individual differences in hidden nature. In the second sense, a need indicates a potentiality or readiness to respond toward a particular end under particular stimulus conditions. The needs account for majority of motivated behaviour. Viscerogenic needs such as need for food that involves bodily tensions and satisfactions, and psychogenic need such as need for affiliation that involve psychological tensions and satisfactions are directly link to the achievement area. The first is the need of achievement, which he defined as the desire to accomplish something difficult; to excel one self and to surpass others, to increase self-regard by successful exercise of talent. The second is the need for in avoidance, defined as the desire to avoid humiliation, quit embarrassing situations or to avoid conditions which may lead to belittlement. Although for subsequent motivation researchers, Murrayââ¬â¢s need proved too numerous and too broadly defined, his influence in the development of the field is unmistakable (Efklides, Kuhl & Sorrentino, 2001). The research and finding of Frederick Herzberg and Abraham H. Maslow is the basis of much of the work in the field of human motivation. In Year 1941, Maslow witnessed a pathetic and beggarly civilian parade, after the bombing of Pearl Harbor, thereafter; Maslow developed his theories of motivation through observation by distinguishing the two types of motives: deficiency motives and growth motives. The previous involve drive reduction and filling an internal lack, while the latter correspond to a higher level of functioning, including pleasurable tension increases and fulfilling oneââ¬â¢s unique potential (Ewan, 2003). Building on Murrayââ¬â¢s work, Maslow form one of the most well recognized theories of motivation. He identified that there is a hierarchical relationship between the different needs that one have and the basic needs have to be met before the higher level of needs can act as behavioural motivators. The hierarchy of needs from the lowest to highest is: physiological (physical survival) needs, safety and security needs, social needs, self-esteem needs and self-actualization needs (Maslow, 1943) (Refer to Appendix 1). However, there were limitations to the hierarchy ofà needs model. In reality, people do not work necessarily in accordance to the levels. They are less structuralizing in satisfying their needs. Many can overcome some needs not being met and go on to higher level. Different people with different cultural backgrounds and in different situations may have different hierarchies of needs too. Furthermore, his theory is almost non-testable. The concept is rather vague with many important questions unanswered such as all the needs to be included in each category. Although Maslow clearly states the characteristics of the self-actualizing individual, he has chosen these features primarily on his own subjective judgment using little objective statistical analysis. And due to the limitations, his perspective generated very little experimental research (Carducci, 2009). Herzbergââ¬â¢s two-factor theory of motivation was based on Maslowââ¬â¢s hierarchy of needs. (Hollway, 1991) In a research conducted by Herzberg and his associates on 200 engineers and accountants, they identified two groups of factors which give explanation on motivation known as the hygiene factor (job context) and motivator factor (job content). The hygiene factor consisted environmental factors such as salary, supervision, status, job security, working conditions, company policy and administration and interpersonal relations. They named this as hygiene factors as it aids to remove potential cause of dissatisfaction in job situation. Although these factors will not motivate people, they must, however, be present or dissatisfaction will arise. In the other group of factors, Herzberg and his associates revealed what they considered to be real motivators or ââ¬Å"satisfiers.â⬠These factors include the work itself, recognition, and advancement, the possibility of growth, responsibility and achievement (Lorenzana, 1993) (Refer to Appendix 2). In short, hygiene factors allow one to satisfy basic needs and avoid pain, while motivators reflect peopleââ¬â¢s need for esteem and self-fulfillment (Sargent, 1990). Herzbergââ¬â¢s were criticized by some researchers as the theory was largely based on research with accountants and engineers, so the findings may not apply to shop-floor employees or clerical staff (Sargent, 1990). The age group, gender, job scope and other significant factors might be overlooked in conducting the research. Besides, salary might be one of the motivation factors too, not just to settle dissatisfaction. One prominent attempt to show the connection between different models of motivation and managerial practice was made byà Douglas McGregor in his book, The Human Side of Enterprise (1960). He wrote in his book that ââ¬Å"Man is a wanting animal ââ¬â as soon as one of his needs is satisfied, another appear in its place.â⬠McGregor was greatly impacted by Maslow, building on Maslowââ¬â¢s hierarchy of needs framework, he came up with two sets of assumptions about people: Theory X and Theory Y. He strongly believed that effective leadership depends on mana gement assumptions about the nature of management and people in general (Sargent, 1990) Theory X stress that the average mankind is naturally lazy, dislike work of any kind and will avoid it whenever possible. One has no ambition and prefers to be led rather than lead and take responsibility. One can be self-centred and unconcerned to the needs of the organization. Moreover, he is gullible and not particularly bright or judicious. Worst, he is resistant to change. They need a mixture of carrot and stick to perform (Lorenzana, 1993) (Refer to appendix 3). Theory Y, on the other hand, defend that the average mankind is not laid-back, nor is he without urge to assume responsibility. He can be self-motivated, and find self-satisfaction in work if the right kind of environment is provided by managers. They are people not by nature passive or resistant to organizational needs (Lorenzana, 1993). One weakness of Theory X is that it exercises a form of social control characterized by strict obedience to the authority of the organization, and maintenance and enforcement of contro l through the employ of oppressive dealings including intimation and mockery of employees. Theory X and Theory Y could hardly be applied as perfect models in the real world. It cannot be accepted too literally due to the dichotomy of unrealistic extremes (Stevens, 2009). Back to where I started from, a more philosophical direction can be used to approach motivation as some theorists see motivation as a much more positive experience. Motivation itself can form behaviours that lead to increases in future motivation. Maslowââ¬â¢s concept of self-actualization could be applied within this framework (Encyclopedia Britannica, 2009). Many theorists build on one another theory in aspiration to come up with a more comprehensive approach to motivation, as well as through the research of psychology and behaviour of one. Though there might be limitations to each theory, they are still vastly used by the modern organization, usually a mixed choices of theories. Substantial improvements in the effectiveness should be seen as the social science will continue to contribute to the devel opment ofà motivation. Physiological Needs Physiological needs are the very basic needs such as air, water, food, sleep, sex, etc. When these are not satisfied we may feel sickness, irritation, pain, discomfort, etc. These feelings motivate us to alleviate them as soon as possible to establish homeostasis. Once they are alleviated, we may think about other things. Safety Needs Safety needs have to do with establishing stability and consistency in a chaotic world. These needs are mostly psychological in nature. We need the security of a home and family. However, if a family is dysfunctional, family members cannot move to the next level because they have safety concerns. Love and belongingness have to wait until they are no longer in fear. Many in our society cry out for law and order because they do not feel safe enough to go for a walk in their neighbourhood. Unfortunately many people, particularly those in the inner cities, are stuck at this level. Need to Belong Love and sense of belonging are next on the ladder. Humans have a desire to belong to groups: clubs, work groups, religious groups, family, gangs, etc. We need to feel loved (non-sexual) by others, to be accepted by others. Performers appreciate applause. We need to be needed. We see numerous examples in advertising where our need for group belonging is tied to consumption of a particular product. Esteem Needs There are two types of esteem needs. First is self-esteem which results from competence or mastery of a task. Second, thereââ¬â¢s the attention and recognition that comes from others. This is similar to the sense of belonging level; however, wanting admiration has to do with the need for power. People, who have all of their lower needs satisfied, often drive veryà expensive cars because doing so raises their level of esteem. Self-Actualization The need for self-actualisations is ââ¬Å"the desire to become more and more what one is, to become everything that one is capable of becoming.â⬠People who have everything can maximize their potential. They can seek knowledge, peace, aesthetic experiences, self-fulfilment, and oneness with God etc. It is usually middle-class to upper-class students who take up environmental causes, go off to a monastery, etc. (Maslow, 1970) Appendix 2: There are two classes of factors that influence employee motivation; intrinsic factors and the extrinsic factors. The intrinsic factors were also called the motivator factors and were related to job satisfaction. The extrinsic factors were called hygiene factors and were related to job dissatisfaction. Motivators (intrinsic factors) led to job satisfaction because of a need for growth and self actualization, and hygiene (extrinsic) factors led to job dissatisfaction because of a need to avoid unpleasantness. The negative or positive KITA or ââ¬Å"kick in the assâ⬠approach to employee motivation yields short- range results, but rarely generates any actual motivation. In fact, to call it an ââ¬Å"approach to motivationâ⬠is to clearly misunderstand motivation as Herzberg understood it. KITA yields movement ââ¬â the avoidance of pain ââ¬â not motivation. Positive KITA, in the form of raises and incentives reduces time spent at work, inflates wages and benefits, and overemphasizes human relations. K-I-T-A techniques fail to instill self-generating motivation in workers. Job content factors, such as achievement and responsibility, are motivators, while job environment factors are hygiene or KITA factors. Motivators are the key to satisfaction. (F. Herzberg, ââ¬ËManagement Review, 1971, pp. 2-5) Appendix 3: Theory X Theory Xââ¬â¢s hard-line approach is grounded in coercion, implicit threats and intimation, close supervision, and tight command and control. Such anà approach typically results in hostility, purposely low output, and hard-line union demands. In contrast, a softer approach might produce an ever-increasing request for more rewards and ever decreasing work output.

Alienation in the 21st Century Is Rife
Alienation in the 21st century is rife. Discuss For| Against| Social networking sites such as facebook, MSN etcSocial networking sites have a profound ability to easily exclude people by specifically targeting certain groups within a community or society. People can at times feel left out or easily targeted when others make unnecessary comments and many friendships or relationships can deteriorate as a result of the great influence it has on peopleââ¬â¢s social lives. People are also losing basic social skills as a result, and are becoming heavily reliant on the simple services provided by the internet to communicate basic messages. People are also lacking sympathy and empathy, slowly becoming more and more self- absorbed. This is also reiterated through the rise of commercial happiness (found through materialistic objects)Cultural alienation Alienation between people of different cultures can lead to terrorism, racial and cultural prejudice and pre-determined assumptions and stereotypes of a particular ethnic group. People can also form groups in a community which, although may bring some together, can alienate people who donââ¬â¢t belong to a particular culture or ethnicity. Alienation between generations Newer generations and older generations differ greatly from one another in many ways including language, values and societal morals. As a result many people may feel alienated when communicating or interacting with other people. Eg: baby boomers vs. generation YAlienation by languageAustralian colloquialism and vernacular can often exclude and alienate people of different ethnic backgrounds. Language used within different suburbs, states and age groups can alienate people. (eg: eshayz, tomozza)Religious alienationAlienation among people of different religious beliefs can lead to terrorism, prejudice, violence and feelings of exclusion. Religious gatherings such as youth groups at institutions like churches can lead to people feeling alienated. | MulticulturalismAwareness and acceptance of other cultures is more apparent within our own society, cultural relativism (not judging another culture by the standards of your own). The integration of cultures within our society through holidays, festivals, art, language, music, film, entertainment, etc has an immense impact on the community as a whole. Social networking sites such as facebook, MSN etcSocial networking sites can also bring people closer together in the way that everybody is connected to another person somehow. It is, in a sense, a virtual community. ââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬â- ââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬âââ¬â- Different social classes/ statusPeople of different social classes can often be prejudiced and discriminated against which can often lead to changing values and treatment among people. FamilyDue to the prominence of work and technology, family life is often strained and relationships between members can be challenged and constricted. There is no longer a sense of belonging in families and not many people feel ââ¬Ëtogetherââ¬â¢ as a result. Instead technological objects seem to be consistent within family life and many seem connected to these as opposed to their fellow family members. This is largely due to the shifting times in our community. |

Holey Soles Essay
This case analysis will focus on the issues surround the lifestyle product company Holey Soles. Psychologist Ann Rosenberg founded the company in September 2002. She initially operated in her garage and backyard, until she recruited Joyce Groote (now current CEO of Holey Soles) and expanded the company into other parts of North America. Holey Soles focuses on creating innovative footwear made from their trademarked technology SmartCel and SoleTek, which is an injection-molded foam technology. As of July 2007, sales had grown at 300% in each of the last two years and the company was ranked number four in the 2006 Profit magazine ranking of Canadaââ¬â¢s Emerging Growth Companies. However as they continue to operate, they find themselves getting pushed back by their number one competitor, Crocs. By mid-2007, Crocs sales were 33 times the sales of Holey Soles. Holey Soles has a revenue target of $40 million by 2009, and to achieve this target, they will need to focus on the issues surrounding their company and hindering its growth. We have decided that the core issue surround the company is how to reach the goal of $40 million. They need to address the possible alternatives of either expanding into other products besides footwear, implementing a more aggressive marketing strategy, changing their 2-year goals completely, or maintaining the status quo. These alternatives will depend on the assessment of the time frame, cost, and current and potential competition. Upon analyzing all situations and alternatives, we have decided that the best solution for Holey Soles would be to expand the company by creating other product lines made form their trademarked technology. Only through this method will they be able to generate enough revenue to meet their $40 million goal. Issues The issues surrounding Holey Soles include the inability to have a high market share due to dominance from Crocs, how to reach the goal of $40 million revenue, and deciding upon expansion. We think the core issue is how to reach the goal of $40 million. Decision Criteria 1.Time frame of implementation: They only have 2 years to make reach their intended goal of $40 million. Considering the high target number, 2 years is a very short time frame, and therefore is an important decision criterion. Sourcing from China to other parts of the world also takes a long time, so it factors in how much product can actually be made in the time frame given. 2.Cost of expansion: To reach a goal of $40 million, an expansion of the company would have to take place. This poses the problem of where capital is going to come from. 3.Current competition: Their number one competitor is Crocs. During the 2-year period to reach a goal of $40 million, Crocs will still be selling at the rate they have been, and may also be working towards goals of expansion. 4.Threat of potential competition: In the 2 year time frame given, whatââ¬â¢s to say that new competitors will not enter the market? As the clog fad continues, more companies are producing similar products as Holey Soles . Even though most of them aside from Crocs have a poorer design with lower quality materials, the possibility of a company suddenly entering with a whole new technology is always possible. Alternatives & Assessments 1.Expand by increasing a more diverse range of products sold. By relying on selling the clogs alone, they will never be able to reach their goal of $40 million, nor be able to overtake Crocs since Crocs has taken so much more of the market share already. With their trademarked foam-injection technologies SmartCel and SoleTek, they should put those towards creating newer and more innovative lifestyle products aside from footwear. They already started with the beach bag, so it proves that it is possible to create other products. They already have an advantage due to their company being defined as products that are ââ¬Å"lifestyleâ⬠centered, rather than simply a ââ¬Å"footwear manufacturerâ⬠.

Feature pegged to election 2012 Essay Example | Topics and Well Written Essays - 750 words
Feature pegged to election 2012 - Essay Example In Florida, early voting is different from absentee balloting since early voting occurs at multiple locations while utilizing similar machines like those applied during Election Day. On the other hand, Florida absentee voters need to move to the administrator of election office, before filling out a mail-in ballot (Coleman, 4). Candidly, absentee votes count as it permits voters, in addition to those who are not able to get to the polling stations due to health issues, as well as the elderly the chance to vote. Furthermore, the existing system offers every support possible, specifically, the system offers a lot of time to register for the ballot online, in addition to sending emails every step of the way for proper verification. Moreover, it has been made much easier for the voter to research the candidates and their issues, with the actual ballot in front of them. Mark Stillwell, who is looking forward to voting in November, believes that the basic absentee voting system is okay, bu t it can be superior if there is an audit trail, which could verify that individual votes are counted. For instance, several Federal laws still guide the department of defense officials, in ascertaining military personnel serving beyond state and overseas when it comes to requesting, acquiring, and casting their absentee ballots. Certainly, this is an obvious disadvantage that suppresses military votes to be decided by only senior civilian officials in Pentagon. Whilst the pros of absentee voting are rather obvious, the cons are fairly ambiguous. The reason being that, absentee ballots, are pegged on decisions from local election officials, who interpret them using their individual state laws (Coleman, 4). Thus, this creates confusion as most of absentee ballots are often discarded due to technicalities. For instance, Erica Stillwell interviewed for this segment, says that ââ¬Å"my ballot came with a "privacy sleeve" that I had to fill out with my personal information so they knew it was my ballot. It's supposed to be separated from my ballot to keep it all confidential, but I think it's a system that could be easily abuseâ⬠. Thus, this has caused her to be a little bit unease regarding the privacy of the whole process. Some of the absentee voters do not feel totally secure that their votes will be counted. Erica Stillwell argues in support of this conception by providing her own experience, ââ¬Å"I also received three identical emails telling me that my ballot had been received, which makes me even more nervous about the validity of the systemâ⬠. Despite of this indecision, she says ââ¬Å"I honestly actually missed all the ceremony built up around Election Day too... I hate standing in line, but I always did feel a certain civic pride going to the polls and coming out with my "I voted" stickerâ⬠. Erica Stillwell fears are by no means unreal, since Florida overseas ballot voting statutes gives room for candidatesââ¬â¢ campaigners to trove, incoming ballots via mail from the state residing abroad. They are also able to mount legal plus public relations battle to influence canvassing boards within their strongholds, so as to waive Florida election regulations in counting the overseas absentee ballots. There are numerous reasons that cause most people to distrust Florida absentee voting process, especially given that most are complaining that they do not feel absolutely convinced that their votes

Media of Social Media on the Society Essay Example | Topics and Well Written Essays - 500 words
Media of Social Media on the Society - Essay Example People do not get the opportunity to experience real life situations because of the social media sites. Social sites lead to individuals believing that they can measure their success using the success of others. They enable most people to feel that they are living a real life because of the activities of a social site. The society expects individuals to act and behave in a particular manner. In addition to, individuals end up equating their success through the likes and comments they get from a social site. It has a negative attitude towards the growth of most young boys and girls in the society. Most societies do not measure their success on the likes and comments on Facebook (Gummow, 22). Social media sites affect the society negatively because it changes the mental set up of most children in the society. Children are the leaders of tomorrow, and they should invest most of their time concentrating on school. The social sites change the perception most people have on the values of the society. Exposure of young children to social leads to the children learning little about their culture (Healey, 32). The society tends to shape their message in a manner to attract many viewers. The social media shapes their messages to attract most viewers. The messages on social media sites are not authentic because they will not reach the intended audience. The social media change the cultures of most societies in the world. It tries to make the life of people better, but it leads moral deprivation of the community (Potter, 23).

The Different Types of Leases Research Paper Example | Topics and Well Written Essays - 1500 words - 1
The Different Types of Leases - Research Paper Example This paper illustrates that in order to obtain business equipment and supplies that can shed its effects on the flow of money, one can rely on lease financing as the possible way to straight up capital. Recent surveys prompt that more than 80% of the business organizations in the United States rely on this alternative at minimum one of the equipment acquisitions. It is forecasted that almost 95% would lease in the future. Lease financing is often referred to as ââ¬Å"leaseâ⬠. It is a contractual agreement involving two parties the lessor and lessee. The lease can be defined as a legal document that must be reviewed by an experienced attorney. The company acts as the lessor grants the individual or group acting as the lessee leasing the product or equipment. The contract assigns the lessee to operate the equipment for some pre-specified time. In the period the lessee is required to make monthly payments to the lessor for providing the opportunity. The lease can be categorized in to the following: lease of finance and lease of operation, sale and leaseback along with direct lease, lease of single investor and leveraged lease, domestic lease and international lease. However, finance lease and operating lease are the most popular leases. A financial lease covers the entire life of the equipment to be leased. A sale and lease can be thought of as one type of financial lease. One can even think of combination lease. This type of lease combines aspects of the popular leases. The effects of the tax can be categorized in the following two ways. The first category is to determine the effects of each flow of cash on taxable income. Rents or another type of fees tend to increase the taxable income while expenditure has the opposite effect. The second category is to compute the amount of the tax to be paid and time when the payment is to be made. After the calculation of the taxable income, the rate of the tax is applied to arrive at the liability. The tax is generally paid in 4 installments. The fourth, sixth, ninth and the twelfth month is regarded as the months of payment for the particular year. The amount of the flows is referred as magnitude.

Managing Org Behavior Assignment Example | Topics and Well Written Essays - 500 words
Managing Org Behavior - Assignment Example Besides communication, I would also ensure that the problem solving skills exhibited by the team are as efficient as possible so that the team can guide itself in case the manager is not available. This is because disagreements are bound to happen at any time within the group. How the group deals with the disagreements would be of great importance to me as the manager. Moreover, when the group is discussing a problem, I would also be concerned about the participation of the members. This is because when all members are engaged, a certain positive level of coordination is present (Tina). Although criticism may have a negative impression at certain instances, I would encourage the team members to provide constructive criticism, which is essential in creativity and innovation. Furthermore, I would also be concerned about the flexibility of the team. Flexibility is very important when the organization intends to make certain changes within the organization. Adaptation of the team members would be of importance to me, as their manager, since the contemporary world demands flexibility because it is highly competitive. Other characteristics would include how much the team is focused, as a good team is able to focus with the issue at hand and avoid interruption. An effective communicator has certain specific characteristics that ensure the message is passed appropriately. Such a communicator is said to be effective because they provide a clear and a concise message to the audience. Clarity is one of the most important aspects in communication since it helps in elimination of confusion. In addition, a concise message is straight to the point and does not waste the audienceââ¬â¢s time. On the other hand, a good communicator understands the audience. This implies that the mode of communication that they adopt does not confuse the audience. An effective communicator also employs empathy for the audience. This involves viewing the

Administrative Power Essay Example | Topics and Well Written Essays - 500 words
Administrative Power - Essay Example Public administration is wholly intertwined in the problems and all the activities of the society, and hence, it does not operate alone (Stillman, 2010). Norton Long argues that, power is the lifeblood and backbone of administration (Stillman, 2010). Power attainment, increase, maintenance, dissipation and loss, are factors that cannot be ignored by administrators. Long argues that, ignoring these aspects can lead to failure and loss of realm. In the case of the Columbia accident, which happened in February 2003, killing seven crew members, the administration was to blame for the loss of lives. The damage suspected by the engineers before the shuttle left orbit was downplayed by the NASA managers, who limited the investigations. External pressure from the white house and the congress to meet the date set for launching, made NASA managers to authorize the launching, even when it was clear that foaming was occurring on the left wing of Columbia. Failure to address issues or risks fully or postponing them, can lead to loss of life, a situation which detracts an organizationââ¬â¢s power. Bureaucracy and internal pressure are key aspects of administrative power, and that partake a significant task in enhancing or detracting the administrative power. Bureaucracy, when properly applied without too much pressure, can enhance an organizationââ¬â¢s administrative power. NASA employees were under internal pressure, to meet a deadline; hence, the seven crew members went ahead with their project to launch, even with the awareness of risks. This caused the American people, who were patriotic to the countryââ¬â¢s endeavors in aerospace, to diminish the value and effectiveness of NASA. Power is a coveted aspect in life, and the blood life of administration, as Long said (Stillman, 2010). Administrators strive to gain and retain power, and in the process, they employ various means to ensure that they remain in power. Long

Pacific Science Center Long Report - Essay Example For instance, the center recently engaged in a 13-month trip dubbed ââ¬Å"Around the Americasâ⬠, in an effort to research and raise the publicââ¬â¢s awareness about the fragile nature of our oceans hence the need to protect and preserve them. The science center is also associated with beneficial community based science programs, which are meant to encourage children and the public at large to appreciate the role of science in society. Some of these include the Science Cafà © and Science on Wheels programs. Further, the center continues to display exhibits that thrill guests and inspire their engagement in scientific projects. One such exhibit is Science on a Sphere, which is an intriguing technological tool that makes use of video projectors and computers to show animated picture of Earthââ¬â¢s atmosphere, land and oceans. The center is guided by its strong mission statement, which asserts that the role of PACSCI is to stir a lifetime interest in science, technology, engineering and math (STEM) through creative and interactive science programs and exhibits. The center further envisions communities where adults and children are motivated by science, understand its primary principles, and apply scientific inquiry and knowledge in practical life situations. This paper explores PACSCIââ¬â¢s position in the American science museum sector, by using analytical tools like SWOT and competition analysis; while further providing recommendations on what the center should do to appeal to a g reater audience and maintain its prominence. The Pacific Science Center stemmed from the US Science Pavilion popularized by the Seattle Worldââ¬â¢s Fair in 1962. PACSCI is, therefore, a pioneer in the scientific museum sector. This is because the center began as a technology and science depository, with large halls full of interactive scientific demonstrations and practical exhibits, and employees or volunteers trained to respond to guestsââ¬â¢

Self centered Essay Example for Free
Self centered Essay In Society, Many people conduct themselves unsympathetic towards one another. A great example of how someone would treat one another in society is in Willa Catherââ¬â¢s short story ââ¬Å"Paulââ¬â¢s Case. Where the Protagonist, Paul, displays a lack of sympathy in the way he conducts himself when he confronts himself with people and stressful situations. For Instance when Paul was ââ¬Å"questioned by the Principal as to why he was there, Paul stated, politely enough, that he wanted to come back to schoolâ⬠(pg171). Even though, he said politely that he wanted to come back to schoolà ¾ he lied. Although, it is important to reconsider that Paul didnââ¬â¢t say anything else, due to fear of disapproval from his father. What was more inappropriate was his appearance of the scandalous red carnation in his buttonhole that he wore to the principalââ¬â¢s office that showed he had a lack of submission towards authority to his teachers. Furthermore, when also confronted by his teacher while he ushered at Carnegie Hall. Paul reflected himself ââ¬Å"the tickets had probably been sent her out of kindnessâ⬠(pg 173), While adding ââ¬Å"she had no business amongst these fine people and gay colorsâ⬠(pg173). By reasoning this way, Paul shows no compassion towards anyone he knows that may be able to receive the rich possessions or entertainment that he longedà for. That he would have never experienced unless he ushered at Carnegie Hall.

Ansoffs Matrix - Planning fo Growth Essay Example for Free
Ansoffs Matrix Planning fo Growth Essay This well known marketing tool was first published in the Harvard Business Review (1957) in an article called Strategies for Diversification. It is used by marketers who have objectives for growth. Ansoffs matrix offers strategic choices to achieve the objectives. There are four main categories for selection. Ansoffs Product/Market Matrix Market Penetration Here we market our existing products to our existing customers. This means increasing our revenue by, for example, promoting the product, repositioning the brand, and so on. However, the product is not altered and we do not seek any new customers. Market Development Here we market our existing product range in a new market. This means that the product remains the same, but it is marketed to a new audience. Exporting the product, or marketing it in a new region, are examples of market development. Product Development This is a new product to be marketed to our existing customers. Here we develop and innovate new product offerings to replace existing ones. Such products are then marketed to our existing customers. This often happens with the auto markets where existing models are updated or replaced and then marketed to existing customers. Diversification This is where we market completely new products to new customers. There are two types of diversification, namely related and unrelated diversification. Related diversification means that we remain in a market or industry with which we are familiar. For example, a soup manufacturer diversifies into cake manufacture (i.e. the food industry). Unrelated diversification is where we have no previous industry nor market experience. For example a soup manufacturer invests in the rail business. Ansoffs matrix is one of the most well know frameworks for deciding upon strategies for growth.

Snow White And The Huntsman Film Studies Essay
Snow White And The Huntsman Film Studies Essay In the epic action-adventure starts out with (Kristen Stewart) who plays the only person in the land fairer than the evil queen, her name, snow white. While the film offers an appropriately exciting take on the fairy tale that inspired it, Snow White and the Huntsman is slow at the beginning of the movie with a confused script that jumps around a bit. Thirty minutes into the film it starts to pick up with its first action war scene against the Dark Army, an assaulting force of glass fighters. The film offers wonderful digital effects during this scheme with the soldiers shattering when struck by swords. Ravenna (the evil queen) seizes control of the entire kingdom, locks snow white up and years pass. More drama begins to unfold as age starts to affect the Queen. In order to sustain and preserve her beauty, the Queen must draw out the essence of youth from young women. The Queen also consults with a digitally animated Magic Mirror, that very interesting to watch. As the story begins to pick up, the Mirrors informes the Queen that Snow White is predestined to destroy her unless she devours the young girls heart. At this point the huntsman is introduced; his name is Eric, a widower who has lived in the Dark Forest, is taken to Queen. She orders him to lead her brother, Finn to search for Snow White. In exchange, she assures him that she can revive his deceased wife, Sarah. The next few action scenes have high intensity with a lot of digital affects within the scary forest full of nightmares to an enormous, drooling, angry goblin thats out to eat anyone that enters his valley. The visual effects continue as they travel through the fairy sanctuary where the fairies and animals alike dwell in harmony. The guides for Snow white and the huntsman are hefty, stocky dwarves who were snow whites loyal friends. The actors who played these dwarfs caught me off guard while watching the film. It seems the movie producer passed over little people for the roles of the seven dwarfs. à Full-sized British actors such asà Ian McShane, Bob Hoskins and Ray Winstone played the roles and were shrunk using digital manipulation and had their faces digitally transmuted onto small the bodies. This took away from the realization of the seven dwarfs if you recognize any of the actors playing the seven dwarfs. I would like to have seen more of the seven dwarfs and I feel they w ere slightly under used. The location of the movie took place in the beautiful United Kingdom. Some of the beach scenes were filmed near the village of Marloes which gives the movie a darker feel. The classic Snow White fairytale was set in Germany and the movie showed these German features throughout the movie. The shape of the castle, the design of the village cottages, and the dark forest which represented Germanys Black Forest brought the classic story to life. The music that was created for the movie was outstanding. It really lifted the film and stood out over the chaos of the battle scenes. The background voice that was used created tension in all the right places, and moved me to the point that I wanted to cry during the dwarfs duet.à The costumes made for the Queen were spectacular. The dresses represented power and elegance with a touch of armor for battle as the story unfolded. I would have no problem seeing it again even though I know the ending. All in all this movie was money well spent. I would whole heartedly recommend this film. It has really given the kiss of life to the fairy tale classic, breathing new air into a new way of storytelling. The acting was well done except for Kristen Stewart playing snow-white. I would have no problem seeing watching this movie again or buying it on DVD.
Teens, Sex, and Virginity - I Was Raped by My Teacher :: Example Personal Narratives
I Was Raped by My Teacher Ken was my voice teacher. I never admired anyone more than him. He meant the world to me. It would be safe to say that we did not have a typical teacher/student relationship. I was infatuated with him. He was tall dark and had the voice of an angel. But he was eleven years older than I was, and he was my teacher. I learned from him, I confided in him, and I trusted him. I never pictured myself being with him. I never dreamt he would think of me as a 'woman' and not just a love-stricken seventeen year-old vocal student. When I began my lessons with Ken, they took place at school, but then somewhere down the line, he wanted them to be at his house. He was the teacher, and I was told that you never argued with what the teacher had to say. Our next lesson, I showed up at his house at 1:00 sharp, ready to sing. I had never been to his house before, and I was a little nervous about seeing it. However, when he opened the door and greeted me with his cute little smile, I knew there was nothing to be nervous about. We started our lesson by singing a few songs for fun (we always sang duets together). He said that I wasn't singing my best and asked if I was stressed. Of course I was stressed! I was the lead in our school musical and it would open in two weeks. "One can never reach their full potential when they are stressed," he said, as he began to rub my shoulders. This was weird for me, but like I said, he was the teacher, and you never argue with the teacher. We finished our lesson , I thanked him and I was on my way out. Before I left though, he took my face in his hands, and he kissed me goodbye. I didn't really know what to do. Had that just happened? Did he just kiss me? Did I kiss him back? Is that wrong? He's too old! I'm too young! He's my teacher! We spoke on the phone several times that week, but never brought up the kiss.

Lead :: essays research papers
Lead is a lustrous, silvery metal that tarnishes in the presence of air and becomes a dull bluish gray. Soft and flexible, it has a low melting point (327 Ã °C). Its chemical symbol, Pb, is from plumbum, the Latin word for waterworks, because of lead's extensive use in ancient water pipes. Itsatomic number is 82; its atomic weight is 207.19. Lead and lead compounds can be highly toxic when eaten or inhaled. Although lead is absorbed very slowly into the body, its rate of excretion is even slower. Thus, with constant exposure, lead accumulates gradually in the body. It is absorbed by the red blood cells and circulated through the body where it becomes concentrated in the soft tissues, especially the liver and kidneys. Lead can cause damage in the central nervous system and apparently can damage the cells making up the blood-brain barrier that protects the brain from many harmful chemicals. Symptoms of lead poisoning include loss of appetite, weakness, anemia, vomiting, and convulsions, sometimes leading to permanent brain damage or death. Children who ingest chips of old, lead-containing paint or are exposed to dust from the deterioration of such paint may exhibit symptoms. Levels of environmental lead considered nontoxic may also be involved in increased hypertension in a significant number of persons, according to studies released in the mid-1980s. As a result, the U.S. Centers for Disease Control in recent years have been revising downward the levels of environmental lead that it would consider safe. At one time, lead poisoning was common among those who worked with lead, but such workplace hazards have been largely curtailed. Lead has been used by humans since ancient times. It was used in ancient Egypt in coins, weights, ornaments, utensils, ceramic glazes, and solder. Lead is mentioned in the Old Testament. The Romans conveyed drinking water in lead pipes, some of which are still in operation. Roman slaves extracted and prepared the lead, describes a disease among the slaves that was clearly lead poisoning. Because of their potential toxicity, lead water pipes are no longer being installed. The greatest single use of lead metal today is in the plates of storage batteries for automobiles. The protective oxidation layer formed by lead in contact with such substances as air, sulfuric acid, and fluorine makes it highly resistant to corrosion. For this reason, lead has been used to make drainage pipes and lead chambers in sulfuric acid factories. It is also used as a roofing material. The softness and malleability of lead make it useful for sheathing telephone and television cables. Lead is used in solder because of its low melting point. When combined with tin, lead forms solder

The AIDS Quilt: Another Dimension :: Free AIDS Essays
The AIDS Quilt: Another Dimension "Jones originally envisioned the AIDS quilt as a message that would call upon the conscience of the nation." (Sturken 186) "The AIDS quilt raises the question of the purpose of mourning. For whom do we mourn when we mourn? The foregrounding of the needs of the living and the creation of a community through the quilt point to mourning not simply as a process for remembering the dead and marking the meaning and value of their lives but also an attempt to create something out of that loss." (Sturken 199) Although the AIDS quilt is thought of by most to be a mourning device, there are in fact panels in the quilt that actually oppose the idea of mourning. In this section of the quilt, one out of the eight sections clearly stands out. It is one that reads: "Terry Sutton; He hated this quiltâ⬠¦and so do we." This panel, surrounded by the seven more traditional panels shows how although, on a broad level, the quilt is thought of as a non-activist mourning attempt, there are definite aspects of activism that show through despite discourses popularly associated with the quilt. The other panels pictured here typify the finds of panels that are made for the victims of AIDS. "In memory ofâ⬠¦" and "we will rememberâ⬠¦" are some of the more common inclusions in the panels. Terry Suttonââ¬â¢s panel is incredibly significant because juxtaposed against the other panels it shows an opposite reaction to the quilt. It illustrates Suttonââ¬â¢s hatred of what other victims and families think is an amazing coping device. More often than not, the families and friends who decide to make panels for AIDS victims think it is a wonderful idea. Although the creators of the Sutton panel are certainly in the minority, creating a panel of this nature makes an intense impact. The "ACT UPââ¬â¢ t-shirt that is included in Suttonââ¬â¢s panel is most likely a symbol of his involvement with the well-known activist group, ACT UP. The letters stand for AIDS Coalition to Unleash Power. They define their organization as follows: "ACT UP is a diverse non-partisan group of individuals united in anger and committed to direct action to end the AIDS crisis. We advise and inform. We demonstrate. We are not silent." Because ACT UP is a well-known activist group, the fact that Terry Suttonââ¬â¢s panel associates him with the group shows the audience his feelings toward the idea of making a quilt as a strategy to fight AIDS.

Common risks, threats, and vulnerabilities Essay
1. What are some common hazards. menaces. and exposures normally found in the LAN-to-WAN Domain that must be mitigated through a superimposed security scheme? A superimposed security scheme will embrace Rouge protocols such as Bit excavation and P2P. Unauthorized web scanning and examining. and unauthorised entree to the web. 2. What is an Access Control List ( ACL ) and how is it utile in a superimposed security scheme? An ACL is a Control list which will let or deny traffic or devices based on specifications defined in the ACL. This ACL by and large is applied and configured on Firewalls. It is utile in a superimposed security attack because from an External point of view it become the first line of defence when hosts attempt to link to the web. 3. What is a Bastion Host? Provide an illustration of when a Bastion Host should be used and how. A ââ¬Å"Bastion Hostâ⬠is a host that is minimally configured package firewall incorporating merely necessary software/services. These are besides referred to as bare metal or ââ¬Å"liteâ⬠and is managed to be overly secure through a minimalist attack. All traffic coming is directed to the Bastion or ââ¬Å"screened hostâ⬠. Outbound traffic is non sent through it. The most common menace to the Bastion Host is to the operating system that is non hardened with extra security applications. 4. Supply at least two illustrations of how the enclave demand to put a firewall at the margin can be accomplished. a. Puting a firewall between two routers and another firewall before a DMZ would be the best demand pick to utilize 5. What is the difference between a traditional IP Stateful Firewall and a Deep Packet Inspection Firewall? a. IP Stateful firewall review takes topographic point in bed 4. when traffic efforts to track the firewall a requested a beginning port and a finish port brace become portion of the session leting the beginning to have information. Stateful review firewalls solve the exposure of allowing all the high numbered ports by making a tabular array incorporating the outbound connexions and their associated high numbered port ( s ) . b. Firewalls utilizing deep package review provides sweetenings to Stateful firewallsââ¬â¢ Stateful firewall is still susceptible to assail even if the firewall is deployed and working as it should be. By adding application-o riented logic into the hardware. basically uniting IDS into the firewall traffic. Deep Packet Inspection uses an Attack Object Database to hive away protocol anomalousnesss and onslaught traffic by grouping them by protocol and security degree. 6. How would you supervise for unauthorised direction entree efforts to sensitive systems? Aclââ¬â¢s and audit logs can be leveraged to corroborate which station is trying to do the unauthorised connexion. 7. Describe Group ID ( Vulid ) : V-3057 in the Network IDS/IPS Implementation Guide provided by DISA? A direction waiter is a centralised device that receives information from the detectors or agents 8. What is the significance of VLAN 1 traffic within a Cisco Catalyst LAN Switch? Describe the exposures associated if it traverses across unneeded bole. VLAN1 traffic will incorporate the STP or crossing tree traffic. CDP traffic. and Dynamic trunking traffic to call a few. If unneeded traffic traverses the bole it could do the switch instability doing it to travel down or go inoperable. 9. At what logging degree should the syslog service be configured on a Cisco Router. Switch. or Firewall device? Syslogs traps should be configured at degrees 0-6. Loging Level 2 10. Describe how you would implement a superimposed. security scheme within the LAN-to-WAN Domain to back up authorised remote user entree while denying entree to unauthorised users at the Internet ingress/egress point. To implement a superimposed security scheme for distant user entree. we would get down with an application based login. such as a VPN -SSL hallmark so pair it with LDAP on a radius or Tacacs+ service. LDAP is bound to Active directory which will leverage Role based entree controls to look into group permissions. 11. As defined in the Network Infrastructure Technology Overview. Version 8. Let go of 3. describe the 3 beds that can be found in the DISA Enclave Perimeter layered security solution for Internet ingress/egress connexions ( i. e. . DMZ or Component Flow ) . 3 types of beds found in the Enclave Perimeter Component Flow include the Network layer security. Application layer security and security of the existent applications themselves. 12. Which device in the Enclave Protection Mechanism Component Flow helps extenuate hazard from users go againsting acceptable usage and unwanted web sites and URL links? The Web Content Filter 13. True or False. The Enclave Protection Mechanism includes both an internal IDS and external IDS when linking a closed web substructure to the public Internet. True. it is required to hold external IDS every bit good as internal IDS. Requirements include holding a firewall and IDS in between thecyberspace confronting router and the internal. ââ¬Å"premiseâ⬠. and router. 14. True or False. Procuring the enclave merely requires perimeter security and firewalls. False. procuring the enclave includes a superimposed firewall attack both on the interior and outside of the web. Sensitive informations can be secured from other sections of the internal web ( internal ) every bit good as Internet links ( external ) . 1 5.

ââ¬ÅCountry Loversââ¬Â by Nadine Gordimer and ââ¬ÅVeronicaââ¬Â by Adewale Maja Pearce Essay
Explore the ways in which relationships are shaped and influenced by traditional cultural expectations in the short stories you have studied. Relationships ââ¬â platonic and intimate ââ¬â are sometimes built from cultural expectations; but to what extent are people willing to go to uphold those traditions? I will discuss two short stories ââ¬Å"Country Loversâ⬠by Nadine Gordimer and ââ¬Å"Veronicaâ⬠by Adewale Maja Pearce, in which both focus on close relationships which are condemned from the start due to strict and uncompromising cultural expectations. Cultural influences are portrayed strongly by the non-British writers; one is set in an unnamed African village, and the other Apartheid South Africa. Both stories tragically show the destructive effect on relationships, when a tenacious fixation with tradition causes them to be obeyed beyond the point of humaneness, and everything else ââ¬â including love ââ¬â is disregarded. In ââ¬Å"Country Loversâ⬠the protagonists Paulus (heir to wealthy farming business) and Thebedi (a black farm worker) form an inter-racial relationship in the period of Apartheid rule in South Africa. During Apartheid the divide between blacks and whites was immense. Skin colour determined every aspect of social life. Whilst the affluent whites had their own well-equipped facilities, living in large houses and having well-paid jobs, blacks had to manage with a much lower standard of life. ââ¬Å"Apartheid laws prohibited most social contact between racesâ⬠(Microsoft Encarta 2006) and inter-racial sex and marriage were strongly opposed by law making it virtually impossible for a blossoming relationship such as Paulusââ¬â¢ and Thebediââ¬â¢s to progress. They stood at two different sides of the track, whilst Paulus was son of a rich farmer, Thebedi worked on his farm. The contrast between them is great; and so their economic and social differences would be deeply frowned upon. An instance of the contrast, is the scene after Paulus and Thebedi met at the riverbed it says ââ¬Å"and each returned home with the dark ââ¬â she to her motherââ¬â¢s hut, he to the farmhouseâ⬠. A hut in comparison to a house proves the extent of Apartheid and the blacks living conditions. Njabulo, also a slave labourer would have lived here, and he had feelings for Thebedi. Njabuloââ¬â¢s relationship with Thebedi is also dictated by the expectations of a black man in that time, and also his limitations because of it. For example, Paulus returned from school, and brought Thebedi gifts, because he could afford to, although ââ¬Å"Njabulo said he wished he could have bought her a belt and earringsâ⬠(line 35). He couldnââ¬â¢t display his love for her, because he didnââ¬â¢t have the means. When Njabulo made arrangements to marry her, he couldnââ¬â¢t offer her parents the customary cow that should have been given in place of Thebedi. This also shows that the customs of the blacks could not be taken under consideration whilst segregation that was going on. Also, when the ââ¬Å"very lightâ⬠(line 114) baby was being born it simply states ââ¬Å"Njabulo made no complaintâ⬠. The preceding sentences had been very long and descriptive with many clauses, but this contrasting short simple one gives it importance and could show that he didnââ¬â¢t care, but could also show that he couldnââ¬â¢t do anything about it and so just accepted it. Despite the fact that it had been proven that Thebedi had had an intercourse with a white man, Njabulo maybe couldnââ¬â¢t ask her about it because he was a second-class citizen and couldnââ¬â¢t do anything. Also, maybe he felt uncomfortable to question her in regards to the baby, because it wasnââ¬â¢t uncommon for white men to rape black women in those times. Cultural expectations forced Njabulo to keep quiet, and so it impacted negatively upon their relationship. There was no trust or compassion between them as he had ââ¬Å"no complaintâ⬠when Thebedi had another manââ¬â¢s child. Despite Thebediââ¬â¢s marriage, the love between Paulus and Thebedi seemed very pure. In line 1 of the story it sets the scene for what the whole story is based upon ââ¬â ââ¬Å"The farm children play together when they are small; but once the white children go away to school they soon donââ¬â¢t play together any more, even in the holidaysâ⬠. It immediately drags us into the harshness of living under Apartheid. The entire tone of the narrator is cool and unemotional, perhaps to show the thoughts and feelings of the time. Most white people didnââ¬â¢t really care about the inequality during the Apartheid system, and so had no compassion towards the blacks or to what they were going through. The unemotional tone of the story could also reflect the harshness of the people that were for apartheid or unsympathetic towards the experiences of black people, as the writer Nadine Gordimer was a strong activist in the anti-apartheid movement. The opening line shows how there is no discrimination when the children are young, but as they get older they discover the divide, and so blacks begin to call whites ââ¬Å"missus and baasieâ⬠and blacks drop further and further behind in schooling. The story uses country specific words to show that it is not set in England such as ââ¬Å"koppiesâ⬠ââ¬â small hill in South Africa. The story sharply contrasts the everyday relationships between whites and blacks as they get older to say ââ¬Å"The trouble was Paulus Esendyck did not seem to realise that Thebedi was now simply one of the crowd of farm children down at the kraalâ⬠. He goes against the norm and continues to entertain their relationship, rather than just stop his feelings for her. The language used here such as ââ¬Å"the troubleâ⬠shows that it was a problem that Paulus could not just forget Thebedi. Even when he grew up and out of childhood and experienced the things of adulthood, it did not discourage his love for her. Although it was expected of Paulus to like these white girls as it suggests in the story ââ¬Å"the sight of their dazzling bellies and thighs in the sunlight had never made him feel what he felt nowâ⬠, ââ¬Å"The head girl of the ââ¬Ësisterââ¬â¢ school was said to have a crush on him he didnââ¬â¢t particularly like herâ⬠he had stronger feelings for Th ebedi. In the story, Paulus and Thebedi both go on a walk but unaware of each other but then meet whilst on the walk. This could symbolise that they each want to follow their own paths, but it leads back to one another, ââ¬Å"they had not arranged this, it was an urge each followed independentlyâ⬠. They then go into deep conversation, and during this scene the writer uses lots of descriptive language and imagery to depict their surroundings, such as, ââ¬Å"twisted and tugged at the roots of white stinkwood and Cape willow trees that loped out of the eroded earth around themâ⬠and ââ¬Å"old, and eaten trees held in place by vigorous ones, wild asparagus brushing up between the trunks, and here and there prickly-pear cactus sunken-skinned and bristlyâ⬠. This technique may have been used prolong Paulus and Thebediââ¬â¢s scene of happiness and contentment with each other ââ¬â ââ¬Å"she laughed a lotâ⬠¦sharing her amusement with the cool shady earthâ⬠. Another view is that nature is the only thing around them, it is not discriminatory and doesnââ¬â¢t judge them allowing them to be happy. The turning point in the story is when Paulus and Thebedi have intercourse and it is a blissful time, it says ââ¬Å"they were not afraid of one anotherâ⬠¦this time it was so lovely, so lovely he was surprisedâ⬠. Although, due to the segregation of the time inter-racial relationships were forbidden (as they were illegal) and so their meetings had to be secret, for being found out would have incurred harsh punishments and being socially shunned. Paulus and Thebedi hide their love from others, specifically by making excuses for Thebediââ¬â¢s gift ââ¬Å"she told her father the missus had given these (gilt hoop earrings) as a reward for some work she had doneâ⬠, and by sneaking in and out of the farmhouse ââ¬Å"she had to get away before the house servants, who knew her, came in at dawnâ⬠. They both lead double lives. Paulus leaves for veterinary school and Thebedi marries Njabulo ââ¬â the lives they ââ¬Å"shouldâ⬠be leading if they stuck to the cultural expectations. Once the baby is born everything changes. The writer constantly refers to childhood, during the key scene when Paulus searches for Thebedi and their baby, ââ¬Å"He drank a glass of fresh, still-warm milk in the childhood familiarity of his motherââ¬â¢s kitchenâ⬠and also ââ¬Å"For the first time since he was a boy he came right in the kraalâ⬠. Children are usually associated with innocence and naivety, and so maybe this was used to contrast with the act of murder he will commit, or maybe to remind the readers of the relationship he had with Thebedi when he was younger. In lines 132-134, the long sentences used increase the suspense and tension for the reader, as they are eager to find out what happens next, whilst the writer rambles on about non-essential information. There is a change in Paulus as he no longer enters into long conversations with Thebedi; his language is short and clipped as he says ââ¬Å"I want to see. Show meâ⬠. After Thebedi shows him his child, she uses an anecdote which corresponds to the situation, ââ¬Å"the gang of children had trodden down a crop in their games or transgressed in some other wayâ⬠¦and he the white one among them must intercede with the farmerâ⬠. This shows that the baby was the product of some ââ¬Å"transgressionâ⬠and the responsibility befell on him, Paulus to put it right. You can see that he felt some sorrow or regret as it says ââ¬Å"he struggled for a moment with a grimace of tears, anger and self-pityâ⬠. The relationship between Paulus and Thebedi had been destroyed because of the cultural expectations, as it says ââ¬Å"she could not put her hand to himâ⬠. Thebedi could not even console her young lover, as she had no idea how he would react, maybe in anger he could hurt her, and he was confused ââ¬Å"I donââ¬â¢t knowâ⬠¦ I feel like killing myselfâ⬠. This was now no longer an intimate relationship although they shared a close moment, a chance to reconcile their love Paulus walked out, because the traditions had made it impossible for them to try and rekindle their affection for one another ââ¬â ââ¬Å"For a moment there was the feeling between them that used to come when they were alone down at the riverbedâ⬠Others opinions and views of Paulus are that the prospect of being prosecuted outweighed his love for Thebedi and his child. He had to reassure that she had never been near the farm house, and willing her to take it away and finally did the only thing he could to make sure he was not found out. The last line summarises the whole story, even though they continued a relationship from childhood it was doomed from the beginning due to the pressures and harshness of living in a segregated society, ââ¬Å"It was a thing of our childhood, we donââ¬â¢t see each other any more. ââ¬Å" Adewale Maja-Pearce depicts the tragic story ââ¬ËVeronicaââ¬â¢ in which two members of a rural African village born and raised together, begin to lead very different lives on the ground of hampering cultural expectations. The narrator Okeke recollects his experiences in the village, and his platonic relationship with a fatalistic childhood friend Veronica. Set in the middle of the last century, views of the roles of men and women were rigid and unyielding. The story shows how African women of the time were subjected to constant pressure and mounting responsibilities which in turn leads to fatal consequences. In Afrcian society, men were traditional ââ¬Å"breadwinnersâ⬠and it was a womanââ¬â¢s role to do childrearing and house work. Veronica automatically adopted the responsibilities of her entire family as ââ¬Ësince she was the eldest childâ⬠¦bringing up the other children had fallen on herââ¬â¢. The adjective ââ¬Å"fallenâ⬠does not show the responsibility in a good light, as it suggests that a heavy burden has been dropped onto her. It also describes her family situation as she had to take on tasks stereotypically associated with men- such as ââ¬Å"chopping firewoodâ⬠, as well as taking on maternal roles such as catering for her siblings. Her father abuses her ââ¬Å"listening to her screamâ⬠, and is described as a ââ¬Å"bruteâ⬠, and her mother described as ââ¬Å"weakâ⬠. Maja-Pearce may have used the characters as allegory for the political views of the African country. Veronica is a symbol of the abused and mistreated citizens whilst her father symbolises the government and their indifference and apathy towards the citizens deprivation, and her mother could symbolise th e ââ¬Å"weakâ⬠bystanders that canââ¬â¢t do anything due to their lack of means. This view also ties in with the fact that historically during this period a civil war would soon be in progress, and also that Maja-Pearce had written several stories that challenge the principles of African society. The relationship between Veronica and Okeke is told solely from Okekeââ¬â¢s point of view as he gives a background, until he talks of his leaving the village. The writer could have done this to show that Veronicaââ¬â¢s situation was probably much worse than Okeke knew about, and so the reader would imagine terrible things would happen to her whilst Okeke heard ââ¬Å"screams in the nightâ⬠, and so empathise with her more. This technique could be seen as building tension and anticipation for when they meet, or to show that this crucial dialogue is a very important part of the story. A turning point in the story when Okeke and Veronicaââ¬â¢s friendship is ended by Okekeââ¬â¢s plans to leave his home village and make a life for himself in the city, whilst Veronica refuses to abandon her family. The parting conversation shows just how much cultural tradition has been impressed on Veronica. When Okeke suggests that she leave the village, she replies ââ¬Å"Me!â⬠. This could be vewed as mock indignance, because she feels that Okeke is telling her to forget her set role in society, or it could be seen as genuine surprise at him suggesting that she should give up everything near to her. Okeke then asks for her reasons for staying and she says ââ¬ËI canââ¬â¢t just leave my familyââ¬â¢.

Effect Of Different Noise Reduction Health And Social Care Essay
Abstract-The intent of this paper is to measure the consequence of different noise decrease filters on computed imaging ( CT ) images. In peculiar, denoising filters based on the combination of Gaussian and Prewitt operators and on anisotropic diffusion are proposed. Simulation consequences show that the proposed techniques increase the image quality and let the usage of a low-dose CT protocol.Index Terms-Computed imaging ( CT ) , denoising filters, image quality, radiation dosageComputed imaging ( CT ) is a wireless in writing review method that generates a 3-D image of the interior of an object from a big series of 2-D images taken on a cross-sectional plane of the same object. In most clinical conditions, CT has been necessary in adjunction to conventional skiagraphy. By and large talking, conventional radiogram depict a 3-D object as a 2-D image, produced by an X-ray tubing, which rotates around the organic structure of the stationary patient. of Hounsfield graduated tables that represents the country of involvement. The available grey graduated table is spread over the chosen scope. For this purpose, two parametric quantities are defined, i.e. , windowing breadth, which defines the difference between the upper and lower bounds of the selected scope, and windowing centre, which represents the centre of the window. After a cross-sectional image is acquired, the patient is advanced through the gauntry into the following stationary place, and so the following image is acquired. Improvement in tubing engineering, computing machine, and hardware public presentations has led to an development of CT scanners, cut downing the acquisition scan times and bettering the declaration. A first development of the traditional CT scanner is the coiling ( or helical ) scanner [ 1 ] . It is based on the uninterrupted patient gesture through the gauntry combined with the interrupted tubing rotary motion. The name of this scanner engineering derives from the coiling way traced o ut by the X-ray beam. The major advantages of coiling scanning compared with the traditional attack consist of its improved velocity and spacial declaration. To farther cut down the scan clip, the multislice CT scanner has been developed [ 2 ] . This system uses multiple rows of sensors. This manner, the throughput of the patient is well increased. However, multislice scanners generate an increased sum of informations compared with the single-slice scanner, and practically, the throughput of patients is limited by the clip taken to retrace the acquired informations. In add-on, diagnostic CT imaging involves a trade-off between the image quality and the radiation dosage ; hence, the decrease of the CT image noise is important to cut down the acquisition clip without deteriorating the contrast and the signal-to noise ratio. The visual image of the anatomic constructions by agencies of CT is affected by two effects, viz. , blurring, which reduces the visibleness of little object, and n oise, which reduces the visibleness of low-contrast objects. During scanning, the sum of blurring is determined by the focal topographic point size and the sensor size, whereas at the clip of image Reconstruction procedure, blurring is due to the voxel size and the type of applied filter. Another common process to scan the whole organic structure, giving 3-D images, is magnetic resonance imagination ( MRI ) , which is based on magnetic belongingss of the H content of tissues. The MRI scanner is a tubing surrounded by a elephantine round magnet. The patient is placed on a movable bed that is inserted into the strong magnet, which forces H atoms in the patient ââ¬Ës organic structure to aline in the magnetic field way. When wireless moving ridges are applied, they perturb the magnetisation equilibrium by tipping the magnetisation in different waies. As the RF moving ridges turn off, the H atoms lose energy breathing their ain RF signals. Different types of tissues generate differen t signals. The collected informations are reconstructed into a 2-D array. MRI is a noninvasive scrutiny because the patients are non exposed to the radiation dosage, MRI is good suited for soft tissues. MRI is more expensive than CT. II. RADIATION DOSE AND IMAGE QUALITY CT histories for 47 % of whole medical radiation, although it represents merely 7 % of entire radiology scrutinies. Hence, the development of techniques for cut downing the radiation dosage becomes indispensable, peculiarly in paediatric applications [ 3 ] . In conventional skiagraphy imagination, it is normally clear when overexposure has taken topographic point. This is non true in CT, because the sum of radiation adsorbed by the patient depends on many proficient parametric quantities, which can automatically be controlled by CT scanners to equilibrate the high image quality and the exposure dosage. Then, it is possible that the differences between an equal image and a high-quality image ( obtained with higher exposure ) are non so instantly apparent. Unfortunately, as the radiation additions, the associated hazard of malignant neoplastic disease is increased, although this is highly little. To adhere the image quality to the radiation dosage, a batch of dose forms were developed. The Computed Tomography Dose Index, along with its discrepancies, includes a set of standard parametric quantities used to depict CT-associated dosage. It is defined as the integral of the dose distribution profile ( measured along a line analogue to the axis of rotary motion of the lamp ) divided by the nominal piece thickness. Many proficient factors contribute to the strength dosage in CT. In sequence, the chief CT parametric quantities and their deductions in the diagnostic quality of the CT tests are investigated. 1 ) Tube current ( in factory amperes ) and gantry rotary motion clip: These parametric quantities are straight relative to the radiation dosage. Their merchandise ( in mAs ) affects the figure of photons emitted by the X-ray beam, and it is responsible for the radiation exposure. Furthermore, an addition in mill amperes produces warming of the anode of the X-ray tubing. 2 ) Tube electromotive force extremum ( kVp ) : It is relative to square root of the dosage. This parametric quantity controls the speed at which the negatrons collide with the anode, and it straight affects X-ray incursion. Furthermore, by utilizing high values of kVp, it is possible to cut down the difference in tissue densenesss, and this can degrade the image contrast. 3 ) Pitch: It is defined as the ratio of the table distance traveled in one 360a-à ¦ rotary motion and the entire collimated breadth of the X-ray beam. A rise in pitch produces a decrease of the radiation dosage but, at the same clip, decreases both the piece sensitiveness and the z-axis declaration. Many CT empirical protocols to set scan scenes have been proposed [ 5 ] . Generally, in CT scrutinies, a high radiation dosage consequences in high-quality images. A lower dose leads to the addition in image noise and consequences in un crisp images. This is more critical in low-contrast soft-tissue imagination like abdominal or liver CT. The relationship between the image quality and the dosage in CT is comparatively complex, affecting the interplay of a figure of factors, including noise, axial and longitudinal declarations, and piece width [ 6 ] . Depending on the diagnostic undertaking, these factors interact to find image sensitiveness ( i.e. , the ability to comprehend low-contras t constructions ) and visibleness of inside informations III. CT IMAGE NOISE CT images are per se noisy, and this poses important challenges for image reading, peculiarly in the context of low-dose and high-throughput informations analysis. CT noise affects the visibleness of low-contrast objects. By utilizing well-engineered CT scanners, it is sensible to pretermit the electronic noise caused by electronic devices [ 7 ] . Then, in the CT image, the primary subscriber to the entire noise is the quantum noise, which represents the random fluctuation in the fading coefficients of the single tissue voxels [ 8 ] . In fact, it is possible that two voxels of the same tissue produce different CT values. A possible attack to cut down the noise is the usage of big voxels, which absorb a batch of photons, guaranting a more accurate measuring of the fading coefficients. In this paper, some image filters to cut down the noise part were proposed. In a first measure, the statistical belongingss of image noise in CT tests were investigated. As evident in the literature, noi se mold and the manner to cut down it are common jobs in most imaging applications. In many image processing applications, a suited denoising stage is frequently required before any relevant information could be extracted from analyzed images. This is peculiarly necessary when few images are available for analysis. A batch of surveies have proved the Gaussianity of the pixel image generated by CT scanners [ 9 ] ââ¬â [ 10 ] . This consequence permits us to set up the stochastic image theoretical account and to carry on a statistical image analysis of CT images IV. MATERIALS AND METHODS In this paper, 20 high-dose thorax CT images supplied by the Radiologist staff of ââ¬Å" G. Moscati â⬠Taranto Hospital have been examined. In peculiar, our attending was pointed to chest scrutinies due to high frequence by radiotherapists look intoing chest pathology, every bit good as the good handiness of this type of images. In fact, in the thorax, CT is by and large better than medical imaging analysis such as MRI for the hollow entrails. Furthermore, lung is the lone organ whose vass can be traced without utilizing contrast media, and this simplifies the image amplification. All images ( 512 A- 512 pels ) were in Digital Imaging and Communications in Medicine format, which represents the criterion in radiology and cardiology imagination industry for informations exchange and image-related information. This standard groups information into information sets, including of import features such as image size and format, acquisition parametric quantities, equipment description, and patient information [ 16 ] . The examined images were acquired by agencies of a coiling CT scanner with the undermentioned acquisition puting: the tubing electromotive force extremum is 120 kVp, the tubing current is 375 ma, and the piece thickness is 7.5 millimeter. Image visual image was performed by utilizing the criterion windowing parametric quantities for thorax CT, i.e. , windowing centre of 30 HU and windowing breadth of 350 HU. Each image was corrupted by linear zero-mean white Gaussian noise to imitate a low-dose CT image. To this purpose, we have simulated the decrease in the tubing current degree by following an sum of noise in understanding with the consequences of old surveies about simulation of dose decrease in CT scrutinies [ 11 ] . To be more precise, we have used a degree noise ( standard divergence = 25 HU ) that about simulates the lowest tubing current degree ( 40 ma ) adopted in CT analysis. This value corresponds to the current degree recommended for paediatric thorax CT scrutinies [ 12 ] . Fig. 1 shows an illustration of an original high-dose thorax image. ] . To cut down the noise consequence, different low-pass filters have mostly been used in medical image analysis, but they have the disadvantage to present film overing borders. In fact, all smoothing filters, while smoothing out the noise, besides take high frequence border characteristics by degrading the localisation and the contrast. Therefore, it is necessary to equilibrate the tradeoff among Fig. 1Original CT image obtained with a high dosage of radiation. noise suppression, image deblurring, and edge sensing. To this purpose, a low-pass filter combined with an border sensor operator was proposed. In peculiar, Gaussian, averaging, and unsharp filters were tested to smooth the noise, whereas Prewitt and Sobel operators were used for border designation. The experimental consequences showed that the combination of Gaussian and Prewitt offers best public presentations. Successively, a nonlinear denoising technique has been tested, and its public presentations have been compared with the Gaussian-Prewitt filtering technique. Anisotropic diffusion is a selective and nonlinear filtering technique that improves image quality, taking the noise while continuing and even heightening inside informations. The anisotropic diffusion procedure employs the diffusion coefficients to find the sum of smoothing that should be applied to each pel of the image. The diffusion procedure is based on an iterative method, and it is described by agencies of the un dermentioned diffusion equation where Iti, J is the strength of the pel at place I, J and at the tth loop ; cN, cesium, cerium, and cW are the diffusion coefficients in the four waies ( north, south, east, and west ) ; parametersa?â⬠¡NI, a?â⬠¡SI, a?â⬠¡EI, and a?à »a?â⬠¡WI are the nearest-neighbor differences of strength in the four waies ; and Ià » represents a coefficient that assures the stableness of the theoretical account, runing in the interval [ 0-0.25 ] . The initial status ( t = 0 ) of the diffusion equation is the strength pels of the original image. The diffusion coefficients are updated at every loop as a map of strength gradient. Normally, the two following maps were used for coefficient computation [ 21 ] : ( 2 ) where K is a control parametric quantity. The first map favours high-contrast borders over low contrast borders, whereas the 2nd emphasizes broad countries over smaller countries. A proper pick of the diffusion map non merely preserves but besides enhances the borders. This map monotonically decreases with the addition in gradient strength a?â⬠¡I. The control parametric quantity should be chosen to bring forth maximal smoothing, where noise is supposed to be present at that place forward, it is possible to cipher K to happen the maximal value of diffusion flow ( hundred a?à » a?â⬠¡I ) and take it to be equal to the noise degree. This manner, the undermentioned K values are obtained for two diffusion maps ( 2 ) [ 23 ] : ( 3 ) where I?n is the standard divergence of the noise calculated in the noisy image background. The appraisal of the noise degree in a corrupted image is usually based on the computation of the standard divergence of the pels in the homogenous zone ( e.g. , background ) . For this ground, the pel indexes of the original image background, matching to the zones where there is no signal ( Ii, ,j = 0 ) , have been calculated. Then, these indexes are used to cipher the standard divergence in the noisy image. In the first estimate, we have supposed that the noise criterion divergence is changeless throughout the image. Therefore, to take into history the non stationarity of noise, we have calculated the K value as a map of local noise features. The noise is assumed to be statistically independent of the original image. We consider the differences in strength in the four waies, i.e. , ( 4 ) It is good known that the noise discrepancy of the amount of two independent noisy signals is the amount of the noise discrepancies of the two constituents. Therefore, it can easy be shown that the discrepancy of the noise is non affected by the operations in ( 4 ) , because the noise is assumed to be a white signal, i.e. , different pels are non correlated. Then, the noise discrepancies of I, DN, DS, DE, andDW are the same. To gauge the local noise criterion divergence, we consider a sub image of size M ( M = 2m + 1 ) , where the undermentioned relationship is applied: ( 5 ) It is possible to observe that the local mean I?D, I, ,j is taken into history. In fact, even if the planetary noise mean is zero, locally, the mean is normally nonzero. The estimated local criterion divergence is replaced in ( 3 ) , obtaining four K values for each diffusion map. The diffusion equation does non take into history the border waies. In fact, they are considered ever vertically or horizontally displayed. It is possible to better the public presentation of the diffusion filter by increasing the action of the filter on the waies parallel to the border and diminishing the filtrating action on perpendicular waies. To this purpose, is modified by adding new footings depending on the border way [ 12 ] , A suited mask of size N is used to pull out a sub image, and the upper limit of the strength gradient is calculated to happen the border way. The size N depends on the image belongingss. If N is excessively little, the figure of mask pels is non sufficient to verify if an border issues and to cipher its orientation. If N is excessively big, it is possible to pull out a sub array incorporating more than one border orientation ; in this instance, the computation of the maximal strength gradient produces wrong consequences. V. RESULTS To measure the consequence of noise add-on on the original images, the comparative RMS mistake eRMS was calculated as follows: ( 7 ) Fig 5 ( a ) loop 0 image where Io is the original high-dose image, I is the original image corrupted by Gaussian noise, and R and C are the row and column Numberss, severally. Experimental consequences have shown that this parametric quantity is, on Fig 5 ( B ) Iteration 1 image Fig 5 ( degree Celsius ) Iteration 2image Fig 5 ( vitamin D ) enhanced image loop mean, approximately 13 % .Successively, ( 7 ) was used to cipher the noise decrease obtained by using the proposed filtering techniques on the corrupted image. In this instance, in ( 7 ) , I represents the filtered noisy image. In a first measure, the filter obtained by uniting Gaussian and Prewitt filters was tested. This technique allows diminishing the mean comparative mistake to 10 % . Successively, the anisotropic filter was tested. Several simulations have been used to put up the filter parametric quantities. In peculiar, a first set of trials has been carried out to compare the public presentations of the filter obtained by ciphering the diffusion coefficients by agencies of the two maps ( 2 ) . The trial consequences show that the 2nd map produces somewhat better public presentations in footings of comparative RMS mistake. Probably, this is due to the belongingss of chest CT images, where the big parts are prevailing with regard to the countries with high contrast borders. Further simulations have been performed to place the figure of loops for the diffusion procedure. Fig. 5 ( a-c ) shows the average values of comparative RMS mistakes obtained in all filtering image trials versus the loop figure. It is possible to observe that, for an loop figure less than 4, eRMS monotonically decreases ; otherwise, eRMS monotonically grows. Therefore, three loops have been used in the filtering trials. Furthermore, several simulations have been performed to find the size of the two masks used to gauge the local noise criterion divergence and border waies, severally. The analysis of trial consequences has led to take a size M = N = 7 for both masks. Finally, the public presentations of the Gaussian-Prewitt and anisotropic filters have been compared. The experimental consequences highlight that, utilizing the anisotropic filter, it is possible to diminish eRMS to about 6 % . Fig. 5. ( vitamin D ) shows an illustration of the public presentation of anisotropic filtering and of filtrating obtained by uniting Gauss and Prewitt operators applied on a noisy image VI. Decision In this paper, an analysis of denoising techniques applied to CT images has been presented with the purpose of increasing the dependability of CT scrutinies obtained with low-dose radiation. First, the chief proficient parametric quantities act uponing the radiation dosage and their deductions for diagnostic quality were investigated. Successively, the chief causes of CT noise and its statistical belongingss were analyzed. Finally, some image filters to cut down the noise part were proposed. In peculiar, a combination of Gaussian and Prewitt filters was ab initio tested, obtaining a RMS of 10 % . Successively, a filtering technique based on anisotropic diffusion was applied. Several simulations have been carried out to take the best filter parametric quantities. This manner, it has been possible to diminish the comparative mistake to about 6 % .
