Hypothesis Testing Essay

In today’s world of statistical research there is a multitude of ways to make new discoveries and formulate new ideas; one way to accomplish this is for researchers to have inquiring minds that need to have their questions answered. To do this they must develop their hypothesis. Then researchers can develop a verbal and numerical hypothesis in which they will be able to test this hypothesis. In patients with Attention Deficit Hyperactivity Disorder (ADHD), there seems to be a malfunction in the brain cells to soak up dopamine, which can lead to ADHD, it causes the patient to lose the ability to focus or retain any attention span (Allan, 2012). Team A will show the statistical outcome of diet versus traditional medications. Common treatments and side effects will be discussed in another slide, along with the importance of eating a balanced diet with â€Å"clean† foods. Results show that eating a high-protein diet with complex carbohydrates and foods with Omega -3 fatty acids seem to play a role in alleviating ADHD symptoms. What seems to do good things for our brains seems to do good things for those that suffer from ADHD. Avoiding foods that are simple carbohydrates like candy, sugars, and foods made with white flour is a good idea, as these foods seem to make matters worse. ADHD and Diet Attention deficit hyperactivity disorder, also known as ADHD, is a developmental disability that usually presents in early childhood and results in a persistent and chronic pattern of learning impairment in school, in social settings, and in daily adaptive functioning. The lasting pattern of inattentiveness and/or uncontrollability or recklessness is more often exhibited and more relentless than which is typically observed in individuals at a comparable level of physical and emotional development. In adulthood, ADHD can affect an individual’s work, behavior, social life, and relationships. ADHD tends to reflect an individual’s normal behaviors but at an exaggerated level. This causes difficulty focusing, following through on tasks, meeting deadlines, and the ability to stay motivated especially during tasks that are tedious and extraneous (Duca, 2010). Some research has shown that diet can have an effect on the symptoms of ADHD. In the past 15 or more years more information has been found linking nutrients with ADHD. Researchers are considering multiple etiologies in regards to the development of ADHD and it has become more evident that diet does play a major role in the foundation of ADHD. Studies have shown that the brain abnormalities that individuals with ADHD have been shown to have are not preprogrammed but instead are a manifestation of genetic susceptibilities to noted risk factors including diet and malnutrition. Particular individuals may be genetically heightened necessities for certain nutrients. When these individuals do not receive these nutrients in their diet they are more vulnerable to the brain abnormalities associated with ADHD (Duca, 2010). Conventionally ADHD is treated with stimulant medications such as Ritalin, Focalin, Dexedrine, and Adderall. These medications work by enhancing the transmission of nor epinephrine and dopamine in the brain but they do not come without side effects such as loss of appetite, insomnia, irritability, depressive symptoms, headaches, fatigue, and nausea. Most of the psychological and conventional medical community does not support nontraditional treatments such as nutrient supplementation, diet manipulation, and environmental and food elimination because they do not feel that there is enough research to show that these methods can permanently alter the symptoms of ADHD (Duca, 2010). From a dietary viewpoint ADHD prevention begins early in life during the first three years when brain growth is rampant. Diet plays an important role during this time to support brain health. Research has shown that the underlying contributor to the etiology of ADHD is imbalances in a child’s diet. A balanced diet free of preservatives, processed sugars, and potential food allergens is helpful in the prevention and intervention of ADHD. A diet rich in organic whole foods, fresh vegetables and fruits, abundant in mineral and phytonutrients, and rich in essential fats are important (Duca, 2010). Numerical and Verbal Hypothesis Statement Based on previously acquired research on how a healthy diet of clean non processed foods can help to lessen the symptoms of ADHD Team A has decided to test this theory to see if it is accurate. The research hypothesis that Team A has created is that: Eating a healthy â€Å"clean† diet can help to lessen the symptoms of ADHD. On the other hand the null hypothesis would claim that a healthy diet has no effect on the symptoms of ADHD and would be just as effective as if the subject ate a diet of 100% processed foods. In order to complete this test Team A will have two populations of people to research, population one will be made up of six people who are all on a diet of pre-chosen healthy foods. Population two will be made up of six people who are not following the specified healthy diet and instead eating what could be considered â€Å"junk† food or â€Å"bad† food. Team A’s hypothesis written in numerical form has to start with identifying  µ=the mean symptoms present in those eating healthy. We will also have to restate the hypothesis which would be written out as (H1)  µ1 <  µ2, simply meaning that the mean of population one will be less then population two. This should be able to prove that population one (the healthy eating group) will have less symptoms than population two (non healthy eating). The null hypothesis states (H0)  µ1 =  µ2 which means that population one will equal population two and there will be no difference between the groups symptoms as a result of changing their diets. Using this information we will be able to properly show a breakdown of the five steps of hypothesis testing that Team A will follow. Five Steps of Hypothesis Testing Five steps are involved in hypothesis testing. The point of the steps is to either prove or to disprove the questions involved. They are useful in evaluating the solutions of an issue or research opportunity. An example is a possible correlation between attention deficit hyperactive disorder (ADHD) and diet. The first step of process includes identification of a null hypothesis and variables involved, or more simply, stating the issue being studied. This is a comparison of two categories. Step one is this case claims that poor diet or malnutrition partnered with genetic susceptibilities potentially do not influence brain abnormalities which are associated with ADHD. The independent variable is diet and is categorical. The dependant variable is ADHD symptoms which are continuous (Davis 2007). The second step of the process involves specifying an alternative hypothesis which suggests a difference of the variables. Our null denied symptoms of ADHD influenced by diet. The alternative to this is that ADHD symptoms decrease with improved diet. Therefore, the two groups of our sample, or the two categories of diet are poor diet and good diet (Davis 2007). Step 3 of this process involves setting a significance or alpha level. In other words, determine the degree to which error is allowed. Type I is alpha and Type II is beta. The confidence level involves type I or type II errors. Whether or not diet influences ADHD symptoms is the question. When the truth is that diet indeed does influence (H0), selecting does not (Ha) would be a Type I error. If the truth is diet does not influence (Ha), then selecting that it does (H0) would be a Type II error (Davis 2007). The fourth part of the process involves calculating the probability of the hypothesis occurring. If this probability ends up being equal to our significance level (alpha/beta) then our null hypothesis that poor diet does not influence brain abnormalities associated with ADHD. If the null is rejected then the alternative is accepted but never with 100% certainty. The fifth and final step is simply describing the results of the study and stating our conclusion in relation to the original question (Davis 2007). Team A’s researcher referenced a study linking dietary needs to improve the functions and abilities for children that suffer with ADHD. Research shows that a contributing factor with ADHS is dietary imbalance in children beginning at a young age of around 3 years old. A balanced diet is said to help improve this imbalance, when the dietary needs are met using whole foods rich in mineral and phytonutrients with rich essential fatty oils (Duca, 2010). Being that the research showed underlying contributions this motivated Team A to further our investigation. Team A already had the knowledge that healthy eating led to proper body function and mechanics, but how dietary could needs improve the functions and abilities of children that suffer with ADHD is what Team A wanted to research further. Team A found that the side effects from medications lead to some disturbing results such as loss of appetite, insomnia, irritability, depressive symptoms, headaches, fatigue, and nausea. This is no way for a child to live and if symptoms can or even have the slightest ability to controlled, then proper diet with â€Å"clean† foods should be the way to proceed. References Allan, S.

Human right issues Essay

India’s earliest settlements are believed to have developed in the culture hearths of the Indus Valley around 2600 B.C.E. and in the Ganges Valley around 1500 B.C.E. These societies were mainly composed of ethnic Dravidians who had an economy based on commerce and agricultural trade. Aryan tribes are believed to have then invaded the area after they migrated into the Indian subcontinent from the northwest. It is thought that they introduced the caste system which is still common in many parts of India today. During the 4th century B.C.E, Alexander the Greatintroduced Greek practices into the region when he expanded across Central Asia. During the 3rd century B.C.E, the Mauryan Empire came into power in India and was most successful under its emperor, Ashoka. Throughout subsequent periods Arab, Turkish and Mongol peoples entered India and in 1526, a Mongol Empire was established there, which later expanded throughout most of northern India. During this time, such landmarks as the Taj Mahal were also constructed. Much of India’s history after the 1500s was then dominated by British influences. The first British colony was in 1619 with English East India Company at Surat. Shortly thereafter, permanent trading stations opened in present-day Chennai, Mumbai and Kolkata. British influence then continued to expand from these initial trading stations and by the 1850s, most of India and other countries such as Pakistan, Sri Lanka and Bangladesh were controlled by Britain. By the late 1800s, India began working toward independence from Britain but it did not come until the 1940s however when Indian citizens began to unite and British Labor Prime Minister Clement Attlee began to push for India’s independence. On August 15, 1947, India officially became a dominion within the Commonwealth and Jawaharlal Nehru was named India’s Prime Minister. India’s first constitution was written shortly thereafter on January 26, 1950 and at that time, it officially became a member of the British Commonwealth. Since gaining its independence, India has undergone significant growth in terms of its population and economy however, there were periods of instability in the country and much of its population today lives extreme poverty. Government of India Today India’s government is a federal republic with two legislative bodies. The legislative bodies consist of the Council of States, also called Rajya Sabha, and the People’s Assembly, which is called the Lok Sabha. India’s executive branch has a chief of state and a head of government. There are also 28 states and seven union territories in India. Economics Land Use in India India’s economy today is a varied mix of small village farming, modern large scale agriculture as well as modern industries. The service sector is also an incredibly large part of India’s economy as many foreign companies such places as call centers located in the country. In addition to the service sector, India’s largest industries are textiles, food processing, steel, cement, mining equipment, petroleum, chemicals and computer software. India’s agricultural products include rice, wheat, oilseed, cotton, tea, sugarcane, dairy products and livestock. Geography and Climate of India The geography of India is diverse and can be divided into three main regions. The first is the rugged, mountainous Himalayan region in the northern part of the country, while the second is called the Indo-Gangetic Plain. It is in this region that most of India’s large-scale agriculture takes place. The third geographic region in India is the plateau region in the southern and  central portions of the country. India also has three major river systems which have large deltas that take over a large portion of the land. These are the Indus, Ganges and Brahmaputra rivers. India’s climate is also varied but is tropical in the south and mainly temperate in the north. The country also has a pronounced monsoon season from June to September in it southern portion. More Facts about India †¢ India’s people are 80% Hindu, 13% Muslim and 2% Christian. These divisions have historically caused tensions between different religious groups. †¢ Hindi and English are India’s official languages, but there are also 17 regional languages that are considered official. †¢ India has several cities that have undergone place name changes such as Bombay being renamed Mumbai. These changes were mainly done in an effort to return the city names to local dialects, as opposed to British translations.

Written analysis Assignment Example | Topics and Well Written Essays - 500 words

Written analysis - Assignment Example For example, Bob Marley’s expected sales are: CU400 is the bonus he earned, according to Exhibit 1. Similar is the case with other workers who got a bonus. Jimi Hendrix, on the other hand, earned no bonus as he failed to meet his target of 41250 units, let alone an excess. Figure 1 exhibits a mighty 9% increase in sales in month 25 (rollout). Till month 47, sales have mainly seen increases, including crossing the peak of 10%. Cost of goods sold as a percentage of sales have seen more declines after month 25. However, they have remained around 63% and have not shown drastic reductions. Wages as a percentage of sales, though, went up by 2% immediately and have not reduced much since. It is evident that Ladbrecks has not seen a considerable deduction in costs. However, it is an incentive plan. By definition, it adds to wages rather than deduct. Cost of goods sold does not cover wages of sales-force (Moore, 2014). Here, they would increase expenses by 2%. However, initial costs must be borne when implementing a change. In the long-run, changes get subtle and rise in sales should be considered. Employees will be satisfied, will provide better customer services and will be motivated to increase sales. The plan should be kept, but changes should be made to effect the motivation of employees who are not meeting their targeted sales. If pay does not motivate them, some other initiative should be adopted targeted to them to ensure further rise in sales. This would decrease the difference in wages/sales percentage and would not impact expenses

Marriages Settled in Heavens - Article Example One contrast is those love marriages, although they are often celebrated with the consent of parents and elders and often in courts too, yet tend to ignore the importance of consent of the elders of the family. Boy and girl fall in love with each other and settle down that they will get married no matter their parents agree or not. On the other hand, arranged marriages are settled by the parents, and the spouses may not even know each other before marriages and in some countries, they may not have even seen each other before they enter into the wedlock. This contains a lot of surprise for them which in most cases, is accepted with delight. When there is parents’ consent involved, there are God’s blessings too which tend to beautify the relationship more than when parents are not happily agreeing. Parents’ support remains with the spouses throughout their lives in case of arranged marriages while in love marriages, it may not be with them.  One contrast is those love marriages, although they are often celebrated with the consent of parents and elders and often in courts too, yet tend to ignore the importance of consent of the elders of the family.

Boy weds girl and both have been brought up with different values, morals, and standards. They bring their values to the other family and in this way, society gets enlightened. These values help to build the foundations of a healthy happy family that tends to serve the society in the long run. Both marriages introduce new ways of living and boys and girls tend to get mature and sensible with the passage of time. They learn the tricks and tactics to deal with difficult situations which means that they learn lessons from their experiences throughout their lives.   In case of arranged marriage, the failure rate is relatively lower. This is because whenever a conflict arises, the parents of both the spouses are there to solve them and support them morally. Also, the spouses know that they have to bring good name to their parents by abiding by the vows they took at the time of marriage.

Current Economic Essay Example | Topics and Well Written Essays - 500 words

Current Economic - Essay Example According to Aversa, May â€Å"was the second month in a row that consumer spending went up by 0.5 percent.† This is a trend showing that May was not merely a fluke, and this could be the start of a sustainable trend. Further supporting that hypothesis was the fact that incomes also rebounded in May. As Aversa asserts, incomes are â€Å"the fuel for future spending.† Thus, it is a reasonable assumption that we could see continued strong performance on this leading economic indicator. Aversa also mentions in her article that construction spending also increased in May by nearly a full percentage point. This increase in construction spending was â€Å"the biggest gain in nearly 1  ½ years,† and was fueled by â€Å"Brisk spending on big government projects, such as hospitals and other health care facilities, and by private builders on commercial construction, such as office buildings, eclipsed continued weakness in the housing sector.† The combined increases in consumer and construction spending arguably illustrate broad economic strength in both the commercial and personal consumer areas leading into the summer months. This article speaks directly to a couple of very fundamental economic indicators. While it is mostly a litany of facts about the state of economic performance in May, the article alludes to the power of incomes and spending to produce a strong economy. Spending, both consumer and commercial, quickly reverberates to other areas of the economy. Without strong consumer and other spending, it is difficult for other factors of economic health to take hold. Manufacturing and production will only result in large idle inventories if spending is low. That means fewer jobs as companies seek to slash there supplies in response to lower demand, and in doing so reduce their overhead costs including employment. On the other hand, strong consumer spending translates into increased manufacturing of supply, which in turn leads to greater hiring and lower

An analysis of ethics in the 21st Century Research Paper

An analysis of ethics in the 21st Century - Research Paper Example Types of ethics will give us information about how ethics are related with various folds of our life. Amongst the type of ethics we will discuss in brief about Business Ethics in our report. This discussion would include details of business ethics as in what business ethics are, how they affect business and limitations of business ethics. After getting information of business ethics we will discuss about ethics in 21st century and finally moving on with the conclusion of report about what we have discussed in the report. Ethics may be defined as the philosophical study of behavior that is considered as correct amongst a particular profession or group. Ethics are also termed as Moral Philosophy. It is the discipline or study guiding about what is morally correct and what not. Ethics and values are essential for the development of every society, state, region or country. Today the world around us is changing with a fast pace thus creating uncertainty in lives. This may be due to cut throat competition and globalization. Thus ethics may serve as a guidance laying principles of conduct which is considered as morally correct. The universal values for natural environment, health and safety, human rights, equality of men and women and principles of human conduct all comes under study of Ethics. It is a broad term covering almost all the spheres of life laying principles for fair behavior (Singer 2011). Business Ethics is about responsibly doing the business. It means that the businessmen must keep away from indulging in unfair trade practices like publish misleading advertisements, adulteration, black marketing etc. The businessmen should supply quality products to their consumers at reasonable prices all the time. There should be no unfair competition and monopolies. Workers exploitation should not be there and they must get proper wages with good working condition. Business Ethics can be divided into two parts

Expectancy theory in nursing Article Example | Topics and Well Written Essays - 500 words

Expectancy theory in nursing - Article Example There are three components of expectancy theory, which are expectancy, valence, and instrumentality. In expectancy, the belief is that the efforts of an individual’s determine their attainment of desired performance and goals. To do so, the individuals have to develop their self-efficacy by assessing whether they have the required skills and knowledge to achieve the desired goals. Goals difficulty occurs when the set goals are set too high or the achievement of the performance expectations are set too hard. This leads to low expectancy especially when the desired results of an individual are un-attainable according to the beliefs of the individual. An individual may also get the perceived control where they believe that there is some degree of control over their expected outcome. If such individuals believe that the outcome is beyond their perceived outcomes, then their ability to influence is low leading to low motivation. In instrumentality, individuals believe that they will receive a reward if they meet the performance expectations set. This may be in form of a promotion, salary increment, or recognition. Valence, on the other hand, is the individuals’ beliefs in the reward of certain outcome. It is based on their goals, motivational factors, and values. Expectancy theory is related to nursing management in that it allows the nurse managers to ensure that their employees are well motivated to maximize on their potential. It ensures that the nurse managers come up with policies to ensure that each successful outcome of the nurses’ performance is rewarded. They ensure that the efforts made by all the nurses will result into attainment of desired goals and objectives (Yoder-Wise, 2014). To do so, the nurses have to have the required belief in their ability to achieve the set goals and ensure that the goals set are not too high for the nurse to achieve. Â  

Critical analysis of life of the species Essay Example | Topics and Well Written Essays - 1250 words

Critical analysis of life of the species - Essay Example And the affairs mentioned by the author are relation of the sexes, the generation, and the nourishment of the offspring. And it is through the significance of sexuality in the life of species and how this sexual impulse helps to establish the feeling of love and care for the offspring. So the major emphasis of the writer is on the importance of sexuality for procreation and the parental love for the preservation. According to the writer the excessive love of the parents for their offspring is the basic conception behind this excerpt. Physical intimacy and sexual affairs are supposed to be the most delicate part of all human relations. Man carefully selects his partner for the fulfillment of his sexual impulse and thus the passionate love takes place. While discussing about the two abstract nouns which are related to the subject i.e. will and the intellectuality, here the author compared the will with the root of the tree, and the intellectuality is compared with the crown. Of course these are the abstract conceptions which are inward and psychological. Outwardly and according to the physiologically the organs which are related to these abstract things are more important and they are the genitals and head. Thus the abstract thing that is will, is fulfilled by the means of the concrete organ such as genitals and the abstract intellectual thing is fulfilled by the head. Here human body is very important for fulfilling the psychological needs. So the author wants to say that the fulfillment of the psychological thin gs is only possible by the body. Here the importance of the body is revealed by the author. Thus the sexual impulse is to be regarded as the inner impulse. The author thus explains about the sexual desire and how it is harmful to castrate this craving. Such castration means degradation of his power of mind and body. Here the author opines that sexual impulse is very essential for the proper physical and psychological

Project Saturn Case Study Example | Topics and Well Written Essays - 1250 words

Project Saturn - Case Study Example Saturn was to be a plant to produce a brand new car; GM had not been introducing a brand new car for some time. The name Saturn bears the name of the rocket ship the astronauts used to go to the moon. Saturn was to combine innovative technique in labor relations and innovative manufacturing technique. Roger Smith said that Saturn was the key to GM's long-term competitiveness, survival and success, and its mission was "to develop and produce an American-made small car that will be fully competitive with the best of the imports ' [and] affirm that American ingenuity, American technology and American productivity can once again be the model and the inspiration for the rest of the world." (Ingrassia) After careful planning, with intervention from governors of different states to have the plant built in their jurisdictions, Smith proceeded with the project in Spring Hill, Tennessee. More than two decades later, a new brand of recession hits the world. GM has a pending application for a bailout by the White House. And Saturn is about to be sold out to whoever wants it. What happened to the GM savior after all these years' It was Smith's dream - the savior concept of Saturn to put GM back on track. In the 1980s, GM was still struggling or was just recovering from the harsh realities of the recession. Yet, it was threatened by other auto giants of the time, like Ford, and the Japanese automakers Honda and Toyota. These companies had their own brand competitive cars and a distinct but effective management. Issue No. 2: How effective was the new brand of management and new technology on Saturn to bring GM to its desired leadership in the industry' The innovative technique in labor relations indeed materialize, but not the technology that Smith envisioned. Smith and the UAW agreed on a Memorandum of Agreement to implement plans for innovative technique in labor relations. Smith and UAW head Donald Ephlin signed the MOU which stated this principle: "We believe that all people want to be involved in decisions that affect them, care about their jobs and each other ' and want to share in the success of their efforts." This kind of effort proved effective and beneficial for the plant employees. They were now part of the management of the plant and even in hiring new employees. They felt they were part-owners of Saturn. But this produced resentment inside GM. Other GM brands viewed Saturn as unfair to them. The first Saturn cars went on sale in the fall of 1990 to great fanfare. When the Japanese auto makers bought one Saturn car and opened it up, they all laughed to what they discovered: "the dashboard had overlapping plastic panels that made it look cheap, and a harsh-sounding engine that stemmed from inferior motor mounts." (Ingrassia) Issue No. 3 - Did Saturn bring GM financial successes, and otherwise' Saturn was behind arch-rival Ford in earnings, quality and every other measure. GM's financial performance was lagging. The quality or different kind of car that Saturn was to build as envisioned by Smith did not materialize. Smith had bought whole companies, like Ross Perot's

The Individual as Described by Emerson and Melville Term Paper

The Individual as Described by Emerson and Melville - Term Paper Example An individual can be described as any kind of specified object or person. Individuality, on the other hand, is the quality or state of being an individual. In particular, individuality examines some of the factors that make a particular individual be different from another. various philosophers have made efforts in trying to explain more about the individual and how he functions in his particular environment and society. One of the best-known philosophers, whose views and perspectives about an individual have been used in many disciplines is Ralph Waldo Emerson and Melville. Ralph Waldo Emerson, who existed between 1803 and 1882, can be described as the leading writer as well as thinker among the transcendentalists of New England (Emerson 23). During the time of Emerson, New England transcendentalism can be said to have been a philosophical and literal movement that was very successful, flourishing in the Massachusetts region and the adjoining areas especially before the time of civil war. Emerson was the son of a very Unitarian minister, being born in Boston. Emerson is said to have lived in Concord, a place that he stayed for a major part of his life (Emerson 34). On the other hand, Herman Melville (1819-1891) was a famous American novelist as well as the writer of poets and various short stories that featured the state of life during the Renaissance period in America (Melville 54). Most of the wr itings by Melville became public between 1846 and 1857, a time which they were published. Most of his writings were inspired by his experiences in life, especially as the common sailor, who moved in the spirit of adventure. Melville was also actively involved in the exploration of philosophy and literature as well as engagement in many of the contradictions that characterized the American society.  Ã‚  

Educational psychology Essay Example for Free

Educational psychology Essay Assessment is the process of collecting, interpreting, and synthesising information in order to make decisions about students; provide learners feedback about their progress and their strengths and weaknesses; judge instructional effectiveness and inform educational policy (American Federation of Teachers, et al. , 1990 as cited in Gage and Berliner, 1998). On the other hand, motivation is simply what moves learners from boredom to interest so that they continue learning. It arouses and directs learner’s activities towards learning over time. Assessments can motivate learners if teachers and students roles are effectively performed. For instance, the role of a teacher can be designing tasks in a way that learners can complete with reasonable amount of effort. Difficult tests should be divided into subgroups that are achievable without excessive effort. The role of the teacher even includes ability to inform learners in advance about the nature of the assessments. In this way, assessments are able to motivate student’s effort to learn. Furthermore, Nicholls (1999) as cited in Stepleton (2001) states assessments will motivate learners if they are not seen as a form of torture to the students. The teacher should ensure that students understand that assessments are only meant to assist learners towards achievement of effective learning and attainment of educational goals. If students understand this, they will value assessments and form a positive attitude towards assessments there by getting motivated to learn. Assessments, if used judicially as in grading t tests and scoring of marks, can motivate learners to learn (Gage and Berliner, 1998). Similarly, it is pointed out that given that learners are labelled on the basis of assessments and that these labels create expectations about learner’s ability, characteristics and educational competence. Teachers have to be careful in labelling students. Stepleton (2001) states that according to self-fulfilment prophecy theory, students learn to behave in line with the label or characteristic that has been applied to them. Hence, if assessments are to motivate students, teachers must avoid labelling learners as poor, dull, incompetent or failures on the basis of quantitative results of assessments in the class. If a student feels the teacher knows him or her as an underperformer, the learner may cling to that mentality. On the other hand, good labels such as excellent, good and wonderful should be encouraged and used appropriately to increase motivation on the students learning efforts.

Childcare Essays Effects of Media to Children

Childcare Essays Effects of Media to Children Effects of Media to Children Media has been a significant part of our daily life, a vehicle for communicating to the public as well as a source of entertainment. Magazines, TV programs, radio, billboards, news, internet, cell phones are the forms of mass media which are considered to be part of our everyday routine. Traditionally, parents serve as primary social models for children; whereas other models may include siblings, teachers, relatives and other persons who are significant in children’s lives. Over time, however, parents’ influence as models to their children is on the decline as a direct or indirect result of technological advancement and alterations in household economics. Aside from their busy schedules (which is common in dual-career and single-parent households), families of today seem to gather around rarely because each member has easy access to his or her own television, telephone, computer, music player, etc.. This set-up would imply that children are more inclined to interact les s with their parents and spend more time on their own. Thus, children could turn their attention from their parents to more accessible diversions, such as television watching. Without their parents’ direct guidance or control, such exposure can become excessive and unguarded. It would not be much of a surprise, if what these children watch did influence their thinking and behavior. Studies conducted by Weiten Lloyd reported that children in the U.S. spend 2-4 hours on TV watching alone and this habit appears to increase as they get older (Kirsh). Children and the youth are media’s darling. Media as perceived by children is full of excitement and wonder, because it brings them to a world of reality as well as make believe. A child development expert T. Berry Brazelton, MD., warns parents that, media is really â€Å"the biggest competitor for our children’s heart and mind† (Steyer). Furthermore, James P. Steyer an advocate for media organization for childr en, in his book regards media as â€Å"the other parent† since at present time children spend much of their time with these different forms of media. In view of the fact that our society is media saturated, parents should be aware of the positive and negative effects of media to children. Media’s positive effects are: First, its academic learning opportunities. â€Å"Over the past 30 years, shows such as Sesame Street, Teletubbies, Barney, and Blue’s Clues have provided academic learning to toddlers and pre-aged children. For older children, programs such as Zoom, Cyberchase, and Zoboomafoo are replete with informative, scientific facts. For pre-teens and teenagers, cable channels such as The Animal Planet, The Discovery Channel, and The Learning Channel offer a wide range of educational fare†(Kirsh). Children that are exposed to educational programs are more likely to adopt to what they are watching , to cite an example children(toddlers) from a non-english speaking country that are expose to shows like Barney are able to learn to speak English although with improper grammar. They learn to communicate with the English language and by the time they attend school learning grammar will be easier for them. The same is true with older children, progra ms shown in the National Geographic Channel, The Animal Planet and Discovery Channel and articles written in their published magazine as well as their websites help them to learn and see what a certain animal looks like, see and explore places that are impossible for human to go to and visit places that are overseas. These educational programs help them to visualize places and animals as well as further explain theories that are learned in the classroom. The second positive effect of media is pro-social behavior learning. â€Å"Pro-social behavior refers to any action that benefits another person. Comforting, sharing, and helping are all examples of pro-social actions† (Kirsh). Many develop mentalists, especially those leaning towards the tradition of Social-Cognitive perspective; argue that much of the changes in children’s behavior may be accounted for by their observation of others. Learning through imitation or more commonly known as Observational Learning, occurs when a child observes and eventually imitates a model’s behavior. Programs designed for pro social behavior learning teaches children to practice social behavior such as sharing, helping when they themselves interact socially. They are thought how to properly respond to problems encountered in the outside world like in school or in the community. For example a child who watches how kids share art materials in completing a project in Sesame Street wi ll the same way share his crayons to a classmate when he attend school. To further explain this impression, a study conducted by Mares in 1986 â€Å"suggest that the viewing of pro social television content can increase positive interactions among youth during play and increase altruism† (Kirsh). On the other hand, although pro social programs are intended to teach pro social behavior the age of the viewer should be considered because children of younger age are more adaptable to such teaching than older children. Despite the positive effects presented media has negative effects as well. Children’s familiarity with these media models could lead them to pick up new behaviors that are not modeled by their own parents such as: First, body image and eating disorder problems. According to the Anorexia Nervosa and Related Eating Disorder organization (ANRED), more than half of teenage girls are on diets or think they should be (Tomeo). TV programs and magazines that show teenage girls that are thin even though unintentional young girls tend to copy their favorite character. In their target to get thin they put themselves to diet, at times they force themselves not to eat to get thin. â€Å"On average, girls begin dieting at the age of eight, and eighty-one percent of ten-year-olds fear becoming fat. A national eating disorder treatment center in 2006 reported that sixty-three percent of elementary school teachers are concerned about eating disorders in their classroom. From where do these gi rls get such a poor self image† (Tomeo). Unfortunately, mass media most frequently foster negative affective body images among youth (Kirsh). Apparently, models are not limited to real people; super heroes, cartoon or video game characters, even television or movie idols, can also serve as symbolic or media models in this case. The second negative effect of media is the introduction to drug use. Commercials give enthusiasm to young viewers because they are entertaining, but the harm it brings to the young minds of children is often overlooked. The youth being exposed in a world surrounded with media, are therefore exposed to adult aimed advertisements like commercials of cigarettes and liquor. According to a group that studies health issues, in 1999 the Henry J. Kaiser Family Foundation concluded that the average child between age eight to 18 spends more than 40 hours using television, radio, billboards and the internet wherein advertising occupies much of the time (â€Å"Youth-Oriented Advertising†). Furthermore, it is a fact according to Gerbner that many of this adult oriented advertisements are purposely designed to be attractive to the youth (Kirsh, p. 337). Take smoking for instance; commercials of cigarette infuse curiosity to the youth in the same way that movies and music videos that contain characters that smoke predispose them to do the same. Moreover, ads contribute to problems such as obesity, alcohol abuse and teen smoking (â€Å"Youth-Oriented Advertising†). To sum up, the discussion revealed that aside from parents and significant people who come in contact with the child, symbolic characters can also be potent models. Taking into consideration the presence of factors that have a pervasive influence on the child’s imitative behavior, the television can be a powerful agent of socialization. Despite its negative effects, however, TV viewing can also have constructive effects on children. Under proper supervision and if viewing is done in moderation, families, particularly parents can harness, and even maximize this medium’s potential as a good source of information and helpful avenue for learning.

Understanding Mobile Technology Development

Understanding Mobile Technology Development The world becomes increasingly interconnected technologically. The use of mobile data has grown surprisingly with the rising use of the smart phones. Therefore, mobile app plays an important role for the todays business. There are three different approaches for developing mobile apps: Native Apps: The Android and iOS are the two widely used app platforms. The Native apps are developed for a specific platform.ÂÂ   So the native apps which are developed for Android devices will not work on iOS devices and vice versa. The native apps are built using native programming languages like Objective C, Java, etc. Each mobile platform offers their proprietary development tools for developing the native apps. (Swift, 2015) The native apps can use the recourses of the devices effectively like camera, sound system, graphics, etc.ÂÂ   Due to make the native apps for specific device, it works fast and reliable to the users. The native apps offer best user experience. The main disadvantage of the native apps is that they will not work on all kinds of devices. So the organization needs to develop different versions of native apps for multiple platforms. Thats why it is costly to build and maintain. Web Apps: The web apps are the mobile version of websites. They are the mobile optimized apps that load within a mobile internet browser like Mozilla, chrome, etc. The users dont need to install the web apps to their mobile devices. So the web apps dont require any space in the devices. Several programming languages like CSS, HTML5, CSS, etc are used to develop the web apps. A web app is easy to develop and can be very simple.ÂÂ   A constant internet connection is required to access the web apps. It may work slow and difficult to engage with users. The financial times has a good mobile web app. (Iversen and Eierman, 2013) Hybrid Apps: The Hybrid apps are the combination of native and web apps. It is written by HTML, CSS and JavaScript and then warp by PhoneGap or Cordova.ÂÂ   The performance of Hybrid app may be reduced due to add an extra layer between the native code and targeted platform. This app is comparatively cheaper than native app and easy to build. It is faster than web app and easy to maintain. Only the native portion of the hybrid apps needs to be rewritten to work it on multiple platforms. So an organization doesnt need to manage a hybrid app in different platforms. So developing hybrid app is economical solution. (Swift, 2015) The Cheswick Green House (CGH) wants to launch their own mobile app due expand their business and more engagement to their customer. A hybrid app is suitable for this type of business because the Cheswick Green House needs a wide acceptability mobile app for growing their business. From the above discussion, we have seen that the hybrid apps have the capability of running on different types of mobile devices. Moreover, this app has more user engagement capability. It is also easy to develop and economical. So I think a hybrid app is suitable for the Cheswick Green House. (McCallister, 2014) The main challenge for the mobile app development is to make it widely acceptable so that it can reach to the optimal number of users.ÂÂ   The performance of the app may be reduced while developers try to make the app widely acceptable. So its a big challenge for the developer to keep the apps simple, clear and responsive. Since most apps run on mobile devices, it is necessary to develop an app with minimum power consumption and resource utilization. Network security is an important part of the todays network. So it is also a key challenge to make the app secure and reliable to the users. (McCallister, 2014) Basically, the mobile app development is a program that runs on the mobile devices like tablet, Smartphone, etc; whereas, the desktop or laptop application is a creation of computer programs that runs on a desktop or laptop devices. Most of the apps for standard computer are developed by HTML, PHP, CSS and JavaScript. On the other hand, the mobile app development depends on a lot of factors. Different programming languages are used to develop different versions of mobile apps. For example, Java is used to build Android apps and swift is used for iOS apps. (McCallister, 2014) In this assignment, we have described three different approaches for developing mobile apps, identified their advantages and disadvantages, selected a suitable approach for the Cheswick Green House and finally justified my decision based on the business operation of the company. We have identified some key challenges for the mobile app development also and made a comparison between mobile and desktop apps. References Iversen, J. and Eierman, M.

Native American Astronomy Essay -- Astronomy Seasons Astronomers Essay

Native American Astronomy For many years astronomers and people alike have constantly heard about the observations and records of the Chinese and Europeans. No other culture can provide as much information as that gathered by the Chinese and Europeans, but there are many other cultures that observed and recorded the night sky, one of those being the Native Americans. During the last fifteen to twenty years archaeoastronomers have uncovered much concerning the beliefs and records of Native Americans. Unfortunately, the methods of keeping records of astronomical events were not as straight forward as the Chinese and Europeans. The Native Americans had to use what they could to record what they observed. Their records were found on rock and cave drawings, stick notching, beadwork, pictures on animal skins and story telling. One of the few dateable events among the various records of Native Americans was the 1833 appearance of the Leonid meteor shower. The most obvious accounts of the Leonid storm appear among the various bands of the Sioux of the North American plains. The Sioux kept records called â€Å"winter counts,† which were a chronological pictographic account of each year painted on animal skin. In 1984 Von Del Chamberlain listed the astronomical references for 50 Sioux, forty five out of fifty referred to an intense meteor shower during 1833/1834. He also listed nineteen winter counts kept by other plains Indian tribes, fourteen of which referred to the Leonid storm. The Leonids also appear among the Maricopa, who used calendar sticks with notches to represent the passage of a year, with the owner of the stick remembering the events. The owner of one stick claimed records had been kept that way â€Å"since the stars fell.† The first notch on the stick represented 1833. A member of the Papago, named Kutox, was born around 1847 or 1848. He claimed that 14 years prior to his birth â€Å"the stars rained all ov er the sky.† A less obvious Leonid reference was found in a journal kept by Alexander M. Stephen, which detailed his visit with the Hopi Indians and mentions a talk he had With Old Djasjini on December 11, 1892. That Hopi Indian said, â€Å"How old am I? Fifty, maybe a hundred years, I cannot tell. When I was a young boy eight or ten years there was a great comet in the sky and at night all the above was full of shooting stars. (Stephen 37). During the lifetime o... ...eir records by building structures that would observe the sun. the Bighorn Medicine Wheel in Wyoming dates to AD 1400 to 1700. Lines drawn between major markings on the wheel point to the location of solstice sunrises and sunsets and also toward the rising point of the three brightest stars that rise before the sun in the summer. About fifty medicine wheels have been discovered, several are thousands of years. Many of them have the same alignment as the Bighorn Medicine Wheel. In Chaco Canyon, New Mexico two spirals carved into the rock by the prehistoric Anasazi can be used as a calendar. A dagger of light penetrates the shadow of adjacent rocks. The dagger moves with the sun to different locations on the spiral.the full pattern also reflects the 18.6 year cycle of the moon as well as the yearly cycle of the sun. The ancient Native Americans were not sophisticated astronomers in the sense of coherent theory behind the movements of heavenly objects, their level of understanding o f the time cycles of the sun, moon and planets was great. The methods for recording and keeping track of the seasonal movements was clever and displays a cultural richness that varies from tribe to tribe.

Object Oriented Development :: essays research papers

BSA400 – Week 3 Individual Paper University of Phoenix, Online Object Oriented Development   Ã‚  Ã‚  Ã‚  Ã‚   When I first started learning how to write code, I had never heard the term â€Å"Object Oriented Development†, or even â€Å"Object Oriented Modeling.† I’m sure that some form of both of these existed, but they might not have been referred to in exactly those words. Fifteen years of coding later, I was finally indoctrinated in the ways of object oriented development.   Ã‚  Ã‚  Ã‚  Ã‚  The first language that I learned to use was BASIC, which was very simple and easy to learn. There were no objects per se, and the code was pretty much written from the top down. Now that I understand the mechanics of object oriented development, I can see that there were parts of the language that could be considered objects, especially from a design point of view. Even though most of my programs were written from the top down and were executed from the top down, a lot of them incorporated logic that was reused multiple times. Blocks of code that contained that logic could usually be segregated from the rest of the code. Instead of appearing multiple times, these blocks would be written only once, but â€Å"called† multiple times.   Ã‚  Ã‚  Ã‚  Ã‚  After BASIC, the next language that I learned was Pascal, named after the seventeenth century French mathematician. Compared to BASIC, Pascal was a much more organized language, with the code separated into actual blocks demarcated with â€Å"BEGIN† and â€Å"END† statements. Against my instructor’s wishes, as well as popular programming practice, I still coded from the top down. I suppose this would have been an issue if I was entering code on punch cards. Luckily, though, these programs were all on monitors, so I could go back and forth through the document, correcting errors and changing the code where necessary.   Ã‚  Ã‚  Ã‚  Ã‚  After Pascal, I learned a few more languages, slowly realizing that maybe it wasn’t a great idea to always code from the top down. Another bad habit that I was slowly trying to rid myself of was writing code without a design document. A design document can be written in either plain English or pseudo code. With plain English, I would just write out what each part of the program should do, and then translate those concepts into code. Pseudo code is a cross between plain English and full code, using elements of both. Even though it might not be easily readable by someone without a working knowledge of that particular language, a lot of the time it could be figured out fairly quickly.

The Relatioship Between Mental Illness and Child Abuse Essay -- Violen

Child abuse affects millions of children every year. Child abuse is defined as â€Å"the hurting or causing harm to a child† (Stewart, 2003, p. 6). Most people do not understand why a parent would want to hurt their children. â€Å"The general belief is that parents who maltreat their children are pathological and certainly not like us† (Polonko, 2005). It is not just parents that abuse the children it is also teachers, babysitters, and daycare workers (Stewart, 2003). Lingern (2008) reported the following: Child abuse was not recognized as a serious problem in the United States until the 1960s. The number of cases reported has increased each year since 1976, when statistics were first kept. In 2004 almost 1.9 million child abuse and neglect cases were reported in the US. Of those reported, nearly 80% of perpetrators were parents. The most common types of child abuse are physical abuse, mental maltreatment and neglect, and sexual abuse (Olive, 2007). â€Å"Physical abuse includes scalding, beatings with an object, severe physical punishment, and a rare form of the abuse called Munchausen by proxy† (National Research Council, 1993, p. 59). Mental abuse is when there is a â€Å"continuing pattern of parental behavior that is psychologically destructive to the child† (Olive, 2007, p. 67). Neglect happens when a child is â€Å"ignored or left alone so much that their well-being is endangered, yet the parent is able, but fails to provide for their basic needs.† (Olive, 2007, p. 67). Lastly, the most unreported type of child abuse is sexual child abuse. Sexual child abuse is â€Å"sexual activity between an adult and a child that is initiated by the adult, and from which the adult receives some sort of sexual gratification† (Olive, 2007, p. 78). ... ...(2007).

Sylvia Plath Theme of Honesty

Jade Bevan Word count: 2821 ‘Plath uses honesty in the character or ‘Esther’ to reflect her personal anxieties’. Explore the theme of honesty in ‘The Bell Jar’ by Sylvia Plath and Emily Dickinson’s ‘Selected Poems’. In the course of your writing show how your ideas have been illuminated by your response to ‘Catcher in the Rye’ by J. D. Salinger and other readings of both texts. The theme of honesty is one that is echoed throughout all three of the authors writing, but is expressed in different ways. Sylvia Plath’s character ‘Esther Greenwood’ in ‘The Bell Jar’ is much like J.D. Salinger’s character ‘Holden Caulfield’ in ‘Catcher in the Rye’. Both characters have a cynical tendency to constantly reveal their inner most opinions about the society around them, discussing their feelings about personalities and appearances. Plath and Salinger were both born in the early twentieth century, despite this had completely opposing backgrounds and upbringings. Plath experienced a quiet and subtle early life in Winthrop Massachusetts, a small seaport town. Whereas Salinger endured a mainstream, fast paced and fashionable beginning in the city of New York.Both these places can make a person incredibly sociable or utterly isolated. Emily Dickinson’s ‘Selected Poems’ also reveals honesty and she confesses her depression very openly and concisely. Being born in the nineteenth century, Dickinson often expresses her opinions of the social placement of women and their restricted lives. She is unlike the ‘stereotypical woman’ of her era, and retaliates in her writing against the inequalities between the sexes. Many critics believe her to be a feminist.Throughout the ‘Coming of age’ novel ‘The Bell Jar’, Greenwood, the protagonist narrator, is constantly breaking down situations, people an d objects around her, like saliva to food. She over analyses the nature of society all around her, and enjoys criticising. When Greenwood first introduces the reader to ‘Doreen’, the mischievous opposite to Greenwood, she contradicts her description beginning with ‘I guess one of my troubles was Doreen’. This statement makes the reader begin to build a negative, unpleasant personality in their minds. However she concludes her escription with ‘a mysterious sneer, as if all the people around her were pretty silly and she could tell some good jokes on them if she wanted to’. This statement shows a clear admiration for Doreen, differing from the initial introduction, however also shows Esther expressing her opinion of Doreen being a mean kind of person, but likes that about her. This could be considered to be a hidden metaphor, for Greenwood’s slow decent into depression and madness, beginning with confusion and uncertainty, typical signs of insanity, which reflects the rest of her story. This is an upfront and honest introduction to the novel.This shows a friendship between the two characters, but a kind that is of a girlish jealous nature. Greenwood clearly admires Doreen’s personality but envies her social power at the same time. Plath also reveals Greenwood’s detachment and alienation from others throughout the novel, isolating her character. This could be to remind the reader of her insane self compared to the sane society and people around her. This can be explained through Greenwood stating ‘I felt myself shrinking to a small black dot against all those red and white rugs, and that pine-panelling.I felt like a hole in the ground’, in this short description of her feelings, she shows vast indications of isolation and depression. The use of the words ‘shrinking’ and ‘small’ reflect her feelings of disappearing and becoming non-existent to the world. Also, descri bing herself as ‘black’ compared to the ‘red and white rugs’ is a use of juxtaposition in the colours, which show how uninteresting she finds herself, being dull and dark in comparison to the bright vibrant rugs, which could imply the rest of society around her. This identification of herself could be considered an honest view of how others perceive her.Another character that is slated by Esther’s criticism is Dr. Gordon. She belittles him by saying ‘How could this Dr. Gordon help me anyway? With his beautiful wife, and his beautiful children, and his beautiful dog, haloing him like a Christmas card’. Dr. Gordon is the psychiatrist who made a mistake during Esther’s electroshock therapy in a terrible way. As the patriarch of the ideal American family, Dr. Gordon seems to represent American society, punishing Esther for going against social expectations, rejecting marriage and family.This shows her honesty and awareness of her soci al differences and views with the rest of society, and is mocking them for being so stereotypical. Her repetition of the word ‘and’ reminds the reader of a list, almost as though Esther is expressing that there are endless differences between society and herself. J. D. Salinger uses the character of Holden Caulfield in parallel with Plath’s character Greenwood, a first person, and protagonist narrator. Holden also suffers with the illness of contradiction, alongside insanity of course, this is another similarity the two characters share.The reader is introduced to an upfront, confident Holden, whom from the setting of the novel, is obviously tense with the topic of family, and starts by stating ‘I don’t feel like going into all of it’, then continues to ‘go into it all’ by describe how annoyed his parents would be if he disclosed any personal information, ‘Especially my father’. He is building a personality of his fat her without realizing, showing a particular conflict with his father, more so than other members of the family. He is also separating himself from his family in that he would openly discuss their issues, whereas his family would not.Essentially, the readers receive an immediate separation and self alienation from his family, and recognise Holden’s critical personality from the start. It is clear that throughout ‘The Bell Jar’, the character of Esther is used by Plath to explore the theme of sexuality, and the effect the 1950’s attitude towards sex had on the women of that time. ‘Then he just stood there in front of me and I kept staring at him. The only thing I could think of was turkey neck and turkey gizzards and I felt very depressed. This description of Buddy’s penis does not only reveal Esther’s criticisms of other further, but we begin to see her real attitude towards sex and Buddy himself. The general theme between Esther and Bud dy is that of sexual tension and virginity, however, although Esther is supposed to be ‘in love’ with buddy, it’s quite clear that she is not attracted to him and is not very fond of him altogether, we see this at the point where she is supposed to be at her most happy or intimate, when Buddy becomes naked in front of her, she feels ‘very depressed’.This may not be completely down to the appearance of Buddy’s private parts, but may be Esther’s attitude towards sex altogether, that she is only so eager to lose her virginity because it was the social norm, and wanted to be ‘part of a great tradition’. Esther shows her honest view upon societies attitude towards sex and its sexist inequalities towards sex when she says ‘I couldn’t stand the idea of a woman having to have a single pure life and a man being able to have a double life, one pure one not. ’ Plath is trying to portray through Esther her rebelliou s opinions towards sexual inequalities between men and women.In the novel, Esther discovers that sexuality is divorced from any expression of love and passion. Sex for women is only a necessity within marriage to have children, and has no relevance with romance or intimacy, Esther could be showing the reader her honest feelings of wanting to have a double life like the men of her era, and be able to experience sexual encounters out of passion and love, no just for starting a family, without being judged. However could also be suggesting her view that all people should remain celibate until marriage, both men and women, but on both interpretations, she is yearning for equality amongst the sexes.With Emily Dickinson’s unconventional style of writing and rebellious grammar, it is not a surprise that her poems do not meet the same literacy concepts as Plath and Salinger. Her poem ‘A Narrow fellow In the Grass’ reflects her individuality and opposing touch of honesty towards sexuality in every stanza. The literal and logical interpretation for the poem is her longing to see a snake in the grass, but only being able to glance at sections of the snake. However, Luann Suhr claims that the poem ‘is in fact about the fear a virgin has towards sex’.This differs from Plath and Salinger’s habit of blurting constant criticism of others, and shows a clear self aggravation and criticism. There are many literary devices used to allude to its sexual theme. Dickinson shows the fear of a virgin by knowing the naturalness of sex yet still being afraid of it. This is accomplished through the literary devices of personification, metaphor, and visual imagery. In the first line of the first stanza, by using the word â€Å"fellow† in her description of the snake she alludes to the snake in regards to man. In colloquial terms, the word snake is often used with regards to male genitalia.A â€Å"narrow fellow† can therefore be read as the male penis. This could also relate to her opinion of men being sneaky like snakes towards the concept of sex, compared to the expectations of a woman to remain celibate, showing her honest neglect of the sexist attitude that society has to sexuality. The second stanza ‘The grass divides as with a comb- Aspotted shaft is seen- And then it closes at your feet and opens further on’ Dickinson has purposely used opposing adjectives to represent her curiosity about sex, how one moment she is captivated by the idea of losing her virginity, then the next her mind closes’ her imagination because she knows she must remain celibate until marriage. It could also represent a previous sexual encounter that was never fulfilled, she is giving the reader an insight into her mind and how ‘dividing’ her mind like this could cause her mental illness to thrive. Once she has captured a small snippet of understanding ‘Aspotted shaft’, her sub conscious â⠂¬Ëœcloses’ her out. Dickinson’s confusion is clear, it sounds almost as though she is at war with herself, insanity, society and again differs from Plath and Salinger in that she does not alienate herself from society, but from her own emotions and desires.Despite this, she carries on fantasizing about this sexual encounter by saying â€Å"sudden is† Dickinson is stating that this male is quick to ejaculate. This can be further proved by the line before which says, â€Å"you may have met him†. The word â€Å"met† can be referring to the sexual meeting, and therefore puts a sexual connotation to the next line. When Dickinson reaches for this thing that scares her so much, it disappears. In the end of stanza four, she says, â€Å"it wrinkled, and was gone†. This is the visual imagery of a penis becoming flaccid.This man she is describing may represent her constant need to please, and fit in. Her honest desperation to communicate her frame of mind seeps through, when the reader finishes the poem to discover, that not even in the final stanza, does she reveal the root of the poem or what its meaning is, leaving readers to feel her confusion, to have a sense of what it would be like to suffer from mental illness, not knowing why or understanding the thoughts she has. Her complete sincerity leaves the reader, in a state of confusion, reflecting her everyday agenda.An aspect of honesty which can be related to all three authors is the honesty with the self and self reflection. Sylvia Plath uses the character of Esther Greenwood to portray her own personal attributes that she struggled to express in reality. We see this when greenwood describes her drink as ‘wet an depressing’, the very statement that a drink is depressing shows how irritating her character is, in the sense that she complains and reverts anything and everything she sees or touches to seem as depressing as she is.This could be Plath expressing thro ugh Greenwood that she is irritated by herself and her own character, the illness is not only discovered, but it irritates her, revealing a full acknowledgement of its existence. This honest analysis in itself portrays that Greenwood sees herself as an irritation to society and this could explain her isolated behaviour, a fear of not being accepted. Another self reflective part of the novel is stage in which Esther begins to lose touch with herself worth, ‘I started adding up all the things I couldn’t do’†¦ I felt inadequate’. Up until the summer before Esther’s senior year, she had done a good job at being a student of literature. However the thought of entering the real world terrifies her. The world she lives in seems to have no place for the literary ideals that she cherishes, which of course is her being pessimistic. This could be forcing her to doubt herself, and self worth towards the world, which may represent Plath attempting to portra y Esther as feeling worthless and useless.Or, another view could be that Esther sees herself as being too complex and misunderstood for the simple minds and dreams of the typical American girl of that era. Emily Dickinson shows honesty with the self and self reflection in the poem ‘The soul has Bandaged moments’ which explores through symbolism, an internalised spiritual and psychological state of experiences of the soul. Which is personified as a woman, and some may interoperate the personification to be Dickinson herself. In the first stanza it says ‘The soul has bandaged moments’ which shows a physical and abstract outlook and insight of the soul.It also implies injury and pain that could metaphorically mean that the soul being personified as Dickinson, she is hurt by her mental illness and attempts to heal herself when ‘she feels some ghastly fright come up to stop and look at her’. This could represent her soul searching and not being fond of what she finds in her mind, or it could alternatively represent her mental illness of depression creeping up on her, it has a sinister feel and may be considered that the mental illness is trespassing, on the privacy of her soul and self.She views this as a form of psychological assault and molester by using words in stanza two such as, ‘caress’ and ‘hovered-o’er’. These bring feelings of uncomfortability and helplessness to the reader. Dickinson is trying to express the mercilessness of insanity. This shows Dickinson’s fear of herself and her capability, some may view it as a panic towards her ever-growing stronger insanity and her ever-growing weaker free will against is. To conclude, a critic once claimed that ‘Writers, who suffer with mental illness, are likely to revolve their writing around complete honesty of their mind.Which, in a sense, creates more emotional and believable connections with the reader, making the insanity se em normal, and allow the reader to feel an attachment with the author’, some may consider this statement to be complete nonsense, however, the analytical evidence shows that there may be some truth in this observation. One may find the ability for Plath, Dickinson and Salinger, all of different era and lifestyle, to have managed to create such personalities and mind wondering scenarios with just the use of a single concept of honesty to be greatly admired.

Carl Jung’s Theory concerning Personality Types Essay

This essay will give an introduction to Carl Jung and what started his research, the essay will discuss Carls Jung’s personality types and their characteristics and will also discuss the Myers Briggs type indicator. The essay will also discuss falsification of type as well as what Carl Jung believed to be the cure for falsification of type. Criticisms of personality type and MBTI will also be discussed and in conclusion this essay will discuss how we can use personality types and MBTI within our own work. Carl Jung & The Beginning of Personality Theory Carl Gustav Jung was born in Switzerland in 1875. His first choice of study was archaeology but he went to study medicine at the University of Basil and while working for the neurologist Krafft Ebing he settled on psychiatry. After graduating he took a position at the Burghoeltzli Mental Hospital, he also taught classes at the university in Zurich, had a private practice and invented word association. In 1907 Carl Jung met Freud in Vienna where the two are meant to have spent thirteen hours talking their friendship started off strong with Jung championing many Freudian ideas but over time their friendship began to deteriorate. Jung felt that Freud focused too much on sexuality and that Freud’s concept of the unconscious was too limited and negative. The official break up happened when Jung resigned from the international psychoanalytic congress. Then in 1913 Carl Jung had a dream, he dreamt that there was a monstrous flood engulfing Europe and lapping at the mountains of Switz erland. He saw thousands of people drowning and civilization crumbling. In the following weeks he continued to have disturbing dreams in which he dreamt of eternal winters and rivers of blood. Carl Jung thought he was becoming psychotic but on the 1st August WWI began and Jung felt there had been a connection between himself and the rest of humanity, thus began Jung’s painful journey of self-exploration which formed the basis for his theory’s. Personality Theory Attitudes & Functions Carl Jung determined that people act and react to stimulus and situations differently. He classified people into two different groups, depending on  how they behaved. Jung called these two different groups attitudes and classified people as either extraverts or introverts; Extraverts – People who are extraverts are better able to deal with external stimulus such as people and objects. They search for things outside themselves to help fulfil them Introverts – People who are introverts are better able to deal with internal stimulus and look inside themselves for fulfilment. In addition to the two attitudes Jung further classified people into four functions types Sensory and Intuitive which refers to our preferred way of collecting information and Thinking and feeling which refers to the way we make decisions. Sensory – People who are more sensory tend to like specific answers and deal in facts and figures Intuitive – People who are more intuitive tend to p refer to gather information through ideas and theories. Thinking – People who are thinkers tend to prefer to make decisions based on scientific fact and concrete truths. Feeling – People who make decisions on their feelings, trust in their emotions and sensitivities. The four functions and two attitudes made up Carl Jung’s original personality types it was later expanded on and two more functions where added which deal with the way people live their lives these are judgers and perceivers ; Judges – Prefer to live in an orderly way and prefer structure and organisation. Perceivers – Prefer to live more spontaneously and are more adaptive. The theory was then used by Katharine Cook Brigg and her daughter Isabel Briggs Myers who after studying Carl Jung’s work extensively turned the theory of psychological types to a practical use. They created the Myer Briggs indicator believing that knowledge of personality types would help woman during WWII who were entering the work place for the first time by identifying which jobs would be more comfortable and effective for them. MBTI focuses on a normal population and emphasizes the value of naturally occurring differences. The two attitudes and six functions types make up for sixteen different combinations which provides detailed characteristics and help us determine which of the types we belong to , each of us has a dominate function with the other three being less dominate. The combinations and some of the characteristics are as follows. ISTJ People who fit in this category tend to be quiet, serious and earn success by  thoroughness and dependability. They value traditions and loyalty. ISFJ People who fit in this category tend to be quiet, friendly, responsible, and conscientious. They strive to create an orderly and harmonious environment at work and at home. INFJ People who fit in this category tend to seek meaning and connection in ideas, relationships, and material possessions. They want to understand what motivates people and are insightful about others. INTJ People who fit in this category tend to have original minds and great drive for implementing their ideas and achieving their goals. They can be sceptical and independent. ISTP People who fit in this category tend to be tolerant and flexible they are quiet observers until a problem appears, then act quickly to find workable solutions to the problems that may arise. ISFP People who fit in this category tend to be quiet, friendly and sensitive. They like to have their own space and to work within their own time frame. INFP People who fit in this category tend to be idealistic and are loyal to their values and to people who are important to them. INTP People who fit in this category tend to seek to develop logical explanations for everything that interests them. Theoretical and abstract, they are interested more in ideas than in social interaction. ESTP People who fit in this category tend to be flexible and tolerant; they take a pragmatic approach and are focused on immediate results. ESFP People who fit in this category tend to be outgoing, friendly, and accepting. They are lovers of life, people, and material comforts. ENFP People who fit in this category tend to be enthusiastic and imaginative. They are spontaneous and flexible and often rely on their ability to improvise and or their language skills. ENTP People who fit in this category tend to be quick, clever and outspoken. They are good at reading other people and can easily become bored by routine. ESTJ People who fit in this category tend to be practical and realistic. They act decisively and move quickly to implement decisions. ESFJ People who fit in this category tend to be warm hearted. They want harmony in their environment and work hard to establish and maintain it. ENFJ People who fit in this category tend to be warm, empathetic and responsible. They are highly attuned to the emotions and needs of others. ENTJ People who fit in this category tend to be blunt and decisive they assume leadership readily. They are usually well informed and well read. â€Å"Jung noted that it is not possible to use the attitudes of Extraversion and Introversion and the Judging and Perceiving functions independently of each other. People who prefer Extraversion will most likely focus their Perception and Judgment in the outer world while people preferring the Introverted attitude, when circumstances permit, will concentrate Perception and Judgment on ideas.† Falsification of Type In our lives we are not always able to work or live in a way that appeals to our strengths. This can happen for a variety of reasons either we are brought up in environments that are unsuitable to our personality types and we adapt to suit the situation or we may be financially unable to follow a career path that would be best suited to our personality type. A person may also be unaware of their strengths and may just have a feeling that they are not living the life they were meant to. Carl Jung believed that if we do not live or work in a way that best suites our personality type then we could develop a falsification of type. This occurs when we are forced to use our less predominate functions for long periods of time. Carl Jung believed that falsification of type could lead to many psychological problems. Carl Jung described Falsification of Type as â€Å"a violation of the natural disposition,† and explained that whenever Falsification of Type takes place a person first becomes anxious and irritable and then if the condition continues a person becomes neurotic. Jung strongly believed that if there was a reversal of type it could be very harmful to the physiological  well-being of a person and could often lead to an acute state of exhaustion. Research has been done which supports Jung’s theory and according to the research of Dr. Richard Haier of San Diego, when an individual is functioning from a style other than their natural lead style, the brain is forced to expend large amounts of energy trying to maintain the unnatural functions. The result is that the brain and brain-body system experience stress, chronic anxiety and exhaustion. Dr. Arlene Taylor worked with people suffering with PTSD and depression over an 11 year period and found that people living in a state of prolonged adaption appeared to display specific symptoms. There are eight commonly seen symptoms in people who appear to be suffering with a falsification of type theses are; 1) Fatigue – Prolonged adaption can require the brain to work up to 100 times harder. 2) Hyper vigilance – Prolonged adaption can create a state of hyper-vigilance as the brain goes on protective alertness. This is a safety mechanism and can show up in a variety of different ways 3) Immune System alteration – Falsifying Type can be thought of as the individual living a lie at some level. Lying can suppress immune system 4) Memory impairment – Cortisol, which is released under stress, can interfere with memory functions. 5) Altered brain chemistry – Prolonged adaption can interfere with hypothalamus and pituitary functions, which can interfere with hormonal balance. 6) Diminished frontal lobe functions – Prolonged adaption is a significant stressor, which can interfere with functions typically associated with the frontal lobes of the cerebrum. 7) Discouragement, fatigue and or depression – Prolonged adaption can lead to the repeated triggering of the conserve/withdraw reaction to stress. This can be especially true for introverted people although it is commonly observed in extroverted types who have been conditioned to introversion. This is far more common than most people (even researchers) believe. Discouragement tends to increase as fatigue increases, which often contributes to the development of depression 8) Self-esteem problems – .Any or all of the other symptoms can be contributed to diminished overall success in life, which directly affect self-esteem. Self-esteem issues can present as lack of confidence or lack of commitment to improving one’s outcomes Jung believed that the only way to cure falsification of type is to develop the functions and attitudes that people are naturally disposed towards. This is a long process where the sufferer will have to first identify their natural leanings and then work towards changing things within their lives so that their work, family and social lives’ are in balance with their natural strengths and attitudes. Criticisms of Personality Types & MBTI One of the main criticisms of personality types and the resulting MBTI is that it because it deals with the mind which is abstract it cannot be scientifically proven and that some of the personality types could be made to fit anyone as the use of the language and terms can be ambiguous. The MBTI also relies on a person answering questions about themselves and people may not be completely honest when answering those questions either because they are unaware of how they would react within a situation or that their perception of themselves is distorted. The way in which the questions are asked is also not specific so people may not know if the question is referring to the way they would react at work or the way they would react at home with friends and family. The MBTI also fails the double blind test in which participants do a test but are given a test done by someone else and asked if it fits them. Most of the participants find a way to make the results fit. One of the other arguments is that while it can be very useful in self-understanding it can also be used either intentionally or unintentionally to pigeonhole people. People are complex and fitting everyone into just sixteen different categories can limit peoples understanding of each other and themselves. It also could be used as an excuse for bad or inefficient behaviour. Conclusion Personality Types and the MBTI is still widely used today, the MBTI is used in company’s both big and small to understand and motivate staff and as a tool for management training. Personality Types and MBTI are also still used by therapist’s to understand their clients, as well as giving the therapist an idea of which therapeutic tools are best suited for each individual client. It can be used either by allowing the client to do a MBTI test that the therapist has acquired from a reputable source (not just a downloaded from the internet) or the therapist can lead a client through a process which will enable the therapist to discern which characteristics the client may lean towards. It is worth saying that an inexperienced therapist may face problems in trying to discern a client’s personality leanings without using a test or formal questions as it takes training and experience to be able to read a client effectively. Despite its critics personality types can be used as one of the tools a therapist can utilise to assist them in the treatment of clients as long as the therapist is aware of the potential problems with using the personality type or a MBTI test , such as pigeonholing a client into a specific category or allowing the client to use their personality type as an excuse or a crutch. Using the theory in balance with other treatments and being aware of some of the problems that may arise from using the personality types or a MBTI test can allow the therapist to approach the treatment of a client in a well-rounded and balanced way that is both beneficial and productive.

Operations Management in Insurance Sector

Operations Management in INSURANCE SECTOR Q. How to measure operational efficiency in service industry? Ans-Insurance companies use KPI indicators to measure operational efficiency and ensure optimum standards. The secret to success for an insurance company is providing the right product, having the right people selling and managing risks associated with it. Insurance organizations use and act on metrics to avoid unnecessary risks. Following are the Key Performance Indicators (KPI) that insurance companies use to measure operational efficiency.Policy Sales Growth Ratio It measures policy sales growth over a set period of time. It is increase in the number of clients over a specified period. It is helpful to gain insights into policy sales trend. The higher this percentage, the better it is. Policy Sales Growth = (Current period sales revenue – previous period sales revenue)/previous period sales revenue Claims Ratio It is defined by claims in a period divided by earned premium in the period. It helps to know the risk of claims and effectiveness of the policy.The ratio needs to be analyzed carefully to understand the risk associated. A higher ratio indicates too many claims compared to premiums and it isn’t good for the company. A lower ratio may indicate difficulty claiming which would lead to customer dissatisfaction. Claims Ratio = Total claims per period/Total earned premiums per period Percentage of Total Lapses It measures the total number of missed payments in a period compared with the policies sold. It helps in understanding why lapses are occurring and stop them from occurring at a high frequency. Read also Exam Operations ManagementA high percentage might be because of inefficient operations such as problems in the payment process. A company constantly improves its operations to decrease the percentage of lapses in each period. Percentage of Total Lapses = Lapses/Policies Sold Average Time to Settle a Claim It measures the time it takes settle claims. A decreasing trend is favorable. Lower time to settle the claim defines higher operational efficiency of the company. Average Time to Settle a Claim = Total no. of days taken to settle all claims/ Total claims Quotas vs.Production It measures the effectiveness of sellers and agents at meeting their targets. It helps in identifying when target sales are below and taking corrective action. A ratio below 1 means targets is not being met. A higher than 1 ratio means brokers are exceeding the target and it is favorable for the organization. Quotas vs. Production = Total Rs. Quoted Business/Total Revenue Top Brokers in Sales Revenue I t ranks brokers based on sales revenue and no. of policies sold. It helps to identify top performers for each category of policies.It also helps to improve the performance of brokers who are lacking behind. Top Brokers in Sales Revenue = Rank top 3 or 10 brokers based on sales revenue Total Benefits as a percentage of premium It is an indicator of financial performance. This measure helps in pricing of insurance policies. It helps to know the risk factors associated with each policy and set fair premiums. Total paid benefits as a percentage of premium = Total paid benefits/Total premium earned Q. How to ensure quality in service business and how to enhance quality in service sector?Ans-There are several ways to ensure and enhance the quality of an insurance company. These are listed below. †¢Six Sigma concepts can be implemented to ensure quality and conform to consumer needs. Six Sigma concepts make use of statistical tools which makes measurement of results easier. †¢Div iding the company into departments based on different categories of insurance such as separate departments for car insurance and health insurance. This would provide better understanding of which categories of insurance should be improved by the company. Deciding on the maximum time to settle an insurance claim. This would allow to improve service and quality of claim processes as claims would be settled more quickly. †¢Online information should be used to provide policy holders with accounts that provide updated information regarding their claims and premium payments. †¢Insurance companies can get into an strategic partnership with mobile banking providers so that customers can pay their premiums through mobile banking †¢A chart showing the updated rankings of brokers should be available to all brokers.This would increase competition and let the brokers know how much they are lacking behind others. †¢Incentives for top performing brokers should also be announced in advance to keep the motivation level high throughout and improve services. †¢Regular training programs should be conducted for brokers in order to increase their marketing and selling skills †¢A complaint center should be established in the premises to deal with the complaints received from customers. The complaints should be discussed and a corrective action plan should be develop to deal with problem.The action plan should be implemented and results must be analyzed †¢A maximum time to act on a complaint should be decided within that time the department has to act on the complaint. The corrective action taken should be documented and implemented within the specified time †¢External benchmarking with other insurance companies might also be helpful in identifying short comings and improving services †¢Define to brokers the criteria of quality customer interaction and to led them act on it

Technologies coming true Research Paper Example | Topics and Well Written Essays - 1500 words

Technologies coming true - Research Paper Example One of his assumptions is that he could, indeed, connect to the past and communicate with his dead father, or that he could link up with the future and connect with people trying to talk to him. According to the professor, time is flexible and it could be manipulated by twisting space. The documentary explains the possibility of using a circulating light beam to twist space and close time to a loop. The key challenge is to get laser power to twist space. The professor uses the principle of flexible time to send particles into the past. The documentary explores the link between energy, space, and time as developed by Albert Einstein. However, the professor acknowledges practical challenges that would make it impossible for the machine to connect to the past from the present moment. Various conditions have to be met in order for the professor to challenge the aspect of time as it appears in reality. It might be important to notice that some of the issues that connect to the questions a bout time are actually based on the acknowledgement of the bridge between the theoretical explanations and the practical difficulties involved. The acknowledgement of the difficulties involved in the practical possibilities of the time machine effectively distinguishes this documentary from many science fiction movies, which have always insisted on the possibility of uniting the past and the future through some technological implements born out of their own imaginations. The documentary separates the possible from the impossible by use of illustrations, theories, and explanations. It might be important to assess the similarities and contrasts between the grounds established in The World’s First Time Machine documentary and the imaginations that run through a science fiction film such as Back to the Future. Whereas the documentary attempts to provide facts about the workability of the time machine, the film begins from the imaginative point of view that already affirms such wo rkability and proceeds to explore the capacity of the machine to influence humanity and human destiny. The science fiction film, Back to the Future directed by Robert Zemeckis, effectively expands on the growing fascination about the possibility of man moving back and forth in time. The film is centered on the exploits of Marty McFly who manages to reverse the misfortunes of his family and friends by accidentally using a time machine invented by his friend Emmet Brown, a renowned scientist. McFly’s travel into the past is made possible after some Libyan terrorists kill the doc for having stolen their plutonian, which he used to power the time machine. McFly eventually learns that he is displaced from the present moment of 1985 up to the distant past of 1955. At this point, he meets his parents before they have begun dating and ensures that they are together in order to ensure the sustainability of the family. He is also able to prevent some of the happenings in the past becau se he had prior knowledge of them when he left 1985 towards 1955. For instance, he is able to protect his future father from the accident, which had brought him and his mother in love at the first place. He also meets the young Doc and convinces him to make possible his travel back into the future. During their encounter in the past, he warns Doc in a letter about his future murder at the hands of the Libyan terrorists. Doc wears a bulletproof vests and he is able to avert death. The second dramatic
