Multiple Regression Term Paper Example | Topics and Well Written Essays - 5000 words

Multiple Regression - Term Paper Example Oftentimes, when a model is too simple that it only contains one independent variable, such a model is of limited value because the predictions made from such models are too inaccurate to be useful in a real-world setting. Thus, when one wants to be able to predict an outcome at a more precise level, it is more advantageous to use the information that may be provided by two or more variables in an explanatory framework (Burt, Barber, & Rigby, 2009). Thus, multiple regression analysis should allow an analyst to arrive at better predictions. For example, a student may want to find out the perfect model to getting high grades in school. Using the results of his individual exams as the dependent variable, he may hypothesize that amount of time spent studying, amount of sleep taken the night before the exam, amount of beer drank the night before the exam, caloric intake (or a fancy phrase for how heavy his meal was) prior to taking the exam, and even the presence of his lucky rabbitâ€⠄¢s foot are possible factors for scoring well in the exam. Using multiple regression analysis, the student may find out that amount of time spent studying, amount of sleep taken the night before the exam, and amount of beer drank the night before the exam are significant predictors of his exam scores. ... For example, oncologists may be interested in the best predictors of lung cancer, educators may want to know what are the best predictors of SAT scores, and psychologists would want to find out which factors best predict depression among a particular age group. These questions may all be answered with the help of multiple regression. 2.0 Computational approach The main goal of linear regression, in this case, multiple regression, is to be able to fit a regression line through a number of given points (Wang & Jain, 2003). This regression line is sometimes called the line of best fit and this is the line that represents the regression model of a given problem. These points are usually best represented graphically in a scatter plot. While it is quite easy to produce a scatter plot when there is only one independent and one dependent variable, multiple regression presents the challenge of having more than one independent variable thus making the practice of making a scatterplot impractic al (Dekking, 2005). 2.1 Least Squares In regression modeling, the basic estimation procedure used is the least squares method (Black, 2010). Since the main goal of linear regression is to fit a line through the points, least squares estimation is used to compute this line in such a way that the squared deviations of the observed points from this line are minimized (Wang & Jain, 2003). 2.2 The Regression Equation The bivariate form of simple linear regression produces a two-dimensional line in a two-dimensional space. This equation is defined by: Y = a + bX, where Y is the dependent variable being forecasted by the regression model, X is the independent variable

Methodology and questionnaires - Essay Example This could be due to a plethora of reasons- like gender discrimination, perceived lack of female managerial qualifications/experience, bias shown towards women showing that they are emotionally not competent to occupy managerial positions, perceived threats of male colleagues during promotions, sexual harassment, need to devote time for household work, inability to work at odd hours and night hours, restricted mobility, etc, All these factors combine to create situations in which the situation of women may be marginalised or even threatened by the hierarchy or the work culture and ethos of the institution. There are several aspects for methodology to be carried out and they use the multiple data collection system. The multiple systems could entail both qualitative and quantitative surveys. The quantitative methodology invokes use of statistical and other measures of quantitative analysis whereas, the qualitative would be in terms of structured interviews. Structured interviews are of standard format which entail open ended or closed ended questionnaires. Open ended questions would give the respondents scope for expressing themselves more verbally than closed ends, in which the questions would respond with either Yes or No. This is important because in a study of this kind, in which both quantitative and qualitative data need to be gathered and expounded, qualitative data need to be structured, open ended and amenable to further research and interpretations. 1. Methodology to deal with Research Question No.1: This research question deals with the need to create new management part time jobs to accommodate women into these positions and make better and more productive use of the women work force’s This could be done though face-to-face interviews with the Top Directors and Senior Management Team of the company regarding the induction of newly created vacancies for women in management positions. The interviews with such executives would be able to throw light

How Musical Theatre Has Developed

How Musical Theatre Has Developed To discuss the historical development of musical theatre, this report will present an analysis of Leonard Bernsteins musical West Side Story. It will demonstrate how the 1961 screen version has been adapted for the stage in the 2009 Broadway revival to suit modern day audiences and show its reflection through time with the use of ideas and different styles as well as social and economic influences affecting the works. The conflict between the two rival gangs that is so central to the story could be further interpreted as a conflict between Catholic and Jewish communities, which was Bernsteins intention in the beginning. However, Bernstein seized on the idea that current racial tensions in New York caused by immigrants from Puerto Rico would provide a more powerful story and he undoubtedly saw that this would also offer him the opportunity to use a range of Latin-American dance rhythms, for he later said: it all sprang to life. I heard rhythms and pulses, and most of all I could sort of feel the form. (Bernstein, 2009, p.58) Much about West Side Story in that time was new and revolutionary. Instead of the old fashioned romance, akin to the earlier musicals, this is a story of bleak despair. Extended dance sequences convey the drama, and in a place of rousing finals, both acts end in murder. Although Shakespeares text is not used, his characters are clearly identifiable: They say Shakespeares plays are timeless because they still speak to the human condition today (Fischbach, 2010) Accordingly Arthur Laurent, author of the original book, got a second chance at his creation, and turned the 2009 Broadway West Side Story revival into the musical he always wanted to make. The Daily Telegraph found: There is nothing new about this production of West Side Story aside from the hot young cast and it is a prime example of why new is not always best. (Lalak, 2010) Social constraints of the time prevented certain usage of language, so some dialogue and lyrics were delivered in Spanish. This made a considerable difference without substantially changing the story. Laurent has given the show a more intimate feeling and made the Puerto Rican Sharks and their girls, more complete as characters. They are frustrated as strangers in their own land, and the use of Spanish immediately evokes their separation from the English-speaking Jets and their girls. The fundamental problems havent changed much since the start of West Side Story 50 years ago, as we continue to wrestle with new cultures arriving. More importantly, though, this production sets the story of the two gangs and a brief and star-crossed love affair between Maria and Tony as a young persons game. The casting here has made the lovers, both breathtaking in their roles, enormously youthful, which gives us more gleeful moments. It isnt to be, of course, but from the moment West Side Story begins with the legendary dance prologue through the neighbourhood, faithfully reproduced by Joey McKneely from the original choreography by Jerome Robbins, the show glows with redolent memories and enchants with brilliant new moments. It plays against a remarkably flexible set by James Youmans, used for maximum effectiveness by director David Saint. the fundamental problem with the show is its depiction of gang violence and the mean streets of New York.: as being said in the Mercury News. (Craig, 2010) That was always a signature of West Side Story, even in the 1961 screen version, but still well presented with fantastic dance sequences which were half-danced and half-mimed. This new form of dance became a visual symbol of a mode of thought. What the characters were feeling and thinking was expressed by their movement and their identities became inseparable from it. However, when the movie was released in 1961 it wasnt the dance which made a big impression, but the social tensions. It showed a fight for urban space, a space that has already been impregnated with cultural symbols and political significations for the relations, interactions, and social actions according to the American Way of Life. In this sense, the movie projected how the Puerto Rican migration to New York City in the forties and fifties not only took over the order of the Anglo-Americans, but how it also constitutes a threat for the assumed monolithic identity of the Anglo-American subject. New York City was shown as a divided territory, economically, racially, and ethnically. Each social-economic group inhabited a space and even neighbourhood border crossings were avoided. West Side Story is up to date not only because of its lengthy dance numbers, emotionally drenched songs and scores, and a contemporary plot that speaks so much of the place and time where the story took place, but also because we are now in a place and time where social-economic issues continue to prevail in every household and community and where racial discrimination is still rampant. The new Broadway revival speaks not only of this shows unwavering popularity but also of the timeliness of the message it delivers, a message of love, peace and harmonious co-existence regardless of race and social-economic backgrounds. This message clearly transcends five decades of an ever-changing political, economic, social and cultural landscape and is still relevant up to this day. West Side Story shows how dancing, acting, singing and design could blend together in unity. Whether its an old version of the musical or a new one, we might say that: it marked the most impressive body of choreography in a single show, and it was acclaimed as Leonard Bernsteins strongest work for the Broadway stage. (Garebein, 2000, p.9)

What is a Distribution Channel? :: Organizations, Production, Shipping

A distribution channel is organizations joined together in the process of making products available to consumers. An effective distribution channel can help improve company sales while lowering costs. An ineffective distribution strategy can be very costly to a company and might even cause financial troubles. This paper will take a look at the logistics, production and shipping strategies of Colgate-Palmolive. This paper will also discuss the marketing channels and areas the Colgate Company can improve on. Logistics, Production and Shipping Having an effective logistics, production and shipping strategy can give companies an advantage over their competitors. Producing and getting products to customers can be costly. Having an effective strategy can help reduce costs and increase profits. Colgate works closely with suppliers in order to increase quality, cost effectiveness and innovation. The company only chooses to work with suppliers that share the same values as the Colgate-Palmolive company (Colgate, 2011). Over the years Colgate-Palmolive has had to take a look at the number of plants the company had and where those plants were located. The company sells products in over two hundred countries and has plants located in different regions around the world. Since 2004 Colgate reduced the number of plants they operated worldwide (Colgate, 2011). The company started to use contract manufacturing rather than doing its own manufacturing (Trunick, 2011). By making these changes the company has been able to control costs more and become more profitable. Products need to find a way from manufacturing plants to the customers. Colgate uses several ocean containers, truckload shipments and smaller truck shipments (Trunick, 2011). Shipping costs can be very costly. With some plants closing travel miles from the plant to the customer grew. Rising gas prices along with the extra miles caused costs to rise (Trunick, 2011). Marketing Channels According to Berry (2010) â€Å"in its most simplistic form, a marketing channel performs the work of moving goods from producers to consumers.† According to Quelch and Laidler (2011) â€Å"In 1987, traditional food stores sold 75% of oral care products, but by 1992 they accounted for only 43% of toothbrush sales and 47% of toothpaste sales.† The distribution strategy for Colgate is through large retail stores, grocery stores, drug stores, dentists and plastic surgeons. Colgate has been very successful in positioning Colgate products in store locations where they would gain customers attention (Khurana, 2010).

Psychology Quiz: The Case of Ralph Tortorici Essay

In 1994, Ralph Tortorici, 26 years old, took a class hostage and ended up shooting one student in the leg and the groin. This kind of act could easily be categorized as one that would be surely convicted to a prison sentence of no less than 15 years. However, Ralph Tortorici’s case was not just because of rage and aggression; it was caused by mental illness – delusion disorder. How the court dealt with Ralph’s case is where things went wrong, and made it a torturous journey for him, ending when he took his life three years after his conviction, by hanging himself in his cell. He was sentenced to 20-47 years in prison, rather than to be sent to a mental institution. Two years before this incident, Ralph showed evidence of mental illness, and was well documented as he went to a university health worker and a state trooper for aid. He claims that a microchip is implanted in his penis as a part of a government experiment, and he could not take it anymore. He claims to hear voices from this microchip, telling him what to do. With such, actions should have been immediately made to intercede Ralph’s delusions, which perhaps wouldn’t have worsened, and more significantly, he might be still alive today. One fact I have learned about insanity defense is that pleading not guilty by reason of insanity isn’t by far the easy way out. Once an individual pleads not guilty by reason of insanity, this person is monitored by the state for the rest of his life. They must report to the state, and they become attached to the state until they die. So unless one is really mentally ill, lawyers do not advise their clients to plead not guilty by reason of insanity. Work Cited â€Å"A Crime of Insanity†. 17 Oct 2002. Pbs. org. 13 Jun 2009. .

6 Steps to Solve Math Problems

6 Steps to Solve Math Problems The ability to solve math problems not only boosts ones abstract thinking, it is also a marketable skill in the workplace as many employers require that their employees have taken several math courses in college. Problem solving is a process of finding the solutions to difficult issues. Whether or not a student major in math, either at the college or university level, being able to solve math problems is very beneficial. The ability to solve math problems not only boosts ones abstract thinking, it is also a marketable skill in the workplace as many employers require that their employees have taken several math courses in college. THE ART OF EFFECTIVE PROBLEM SOLVING Though solving math problems seems awfully tedious in nature or even overly difficult to the novice, the practice is essentially solving a problem. And whenever a problem emerges, there is at least one solution to that problem. There is a multitude of ways to solve a math problem. It involves visualizing, approaching and solving math problems in a detailed set of instructions the student should refer to in the event a math problem seems insurmountable. These Are the Best Steps to Follow: STEP 1. Determine the kind of math the problem is calling for. Does this particular math problem call for multiplying fractions? Solving algebraic equations? Solving quadratic equations? Knowing where to start and what school of math is being incorporated is key in helping the student solve their problem. STEP 2. Review what has already been covered in the math course for which this particular assignment, or math problem, has been given. If it’s a specific formula, or set of formulas, that the problem calls for, more than likely the student can find the formula in the chapters or sections their professor has already covered over the course of the term or semester. Most academic institutions offer numerous resources for students struggling with math problems. STEP 3. Begin to solve the problem, apply knowledge and skills already learned in the course. Identify what the problem is calling for and read the directions, if they are present, very carefully. At times, the system of â€Å"guess and check† may help; in other cases, use objects and other such tools to model the problem – sometimes a visual illustration of the problem may serve the student best. Look for patterns, use logical reasoning, and work backward, if possible. STEP 4. Write down and show each step. Sometimes, by writing down their work, the student who may be a visual learner may best solve their problem – or this may overcome a set of obstacles standing in their way of solving the problem. This tactic allows the student to track and even double-check their approach to the problem as well as their mental process of getting the needed results. The student who is struggling with a math assignment must never attempt to solve the entire problem in their head. STEP 5. Verify that the answer is correct and makes sense to the student if they are in the future tested on solving such math problems.  Often in most textbooks, in math courses, especially, the answer is in the back of the book – that is if an assignment is taken directly from the textbook. STEP 6. The student must always remember that their professor’s job is to help them understand the math that the course calls for. So, the student should approach their professor in the event a math problem presents difficulties. Most academic institutions employ the student body’s most skilled math students as tutors for students whose strengths are not math-oriented. This kind of service is often incorporated in the student’s tuition, so they should certainly take advantage of it.

Free Essays on Extremist Groups

from the Koran out of context and blow everything out of proportion so they can manipulate other people to believe in the false ideals.... Free Essays on Extremist Groups Free Essays on Extremist Groups How the extremist (misplaced zeal) of the Al-Quede groups could be explained as growing out of the basic spirituality of Islam? The Koran is the Muslim’s holy book is meant to give us history of the world and let all mankind live with good moral standards. However, not all people maintain these standards in their day-to-day living. Muslim’s are religious people and believe the words of the Koran. The average Muslim is anti-violence and does not even want to be associated with any beliefs of the Taliban. Since the violent attacks on September 11, the Muslim’s have been trying to protect their reputation and hope that people realize they are not violent and that they are totally against this vicious attack. The Taliban considers themselves Muslims, even though they do not follow the terms of the Koran. They can be compared to another extremist group know as the Ku Klux Klan. Both groups rearrange their religious beliefs so they can use it in negative ways. They are taught and sometimes even raised from childhood to follow the steps of their evil beliefs. They would even sacrifice their own lives for these beliefs. When the Taliban does not get what they want, they usually hurt innocent people who have nothing to do with the actual problem. If they had a problem with people in the government, they should go after the government, instead of innocent people. The problem with these groups is that once they have a taste for power, they will never stop. They take the words from the Koran out of context and blow everything out of proportion so they can manipulate other people to believe in the false ideals....

Advantages and Disadvantages of the Epidural

Advantages and Disadvantages of the Epidural Is epidural the best of all words – no pain but full consciousness? (Yerby, 2000). Discuss During pregnancy many women give some thought on what they will do to cope with labour pain. Some women aim to have the most natural type of birth, with the least possible pharmacological interventions. Others request a pain free labour, such as opting for an epidural anaesthesia as a type of pain relief. But do women actually know about the risks epidural anaesthesia can create for them and their baby? Or do they opt for it just because they heard other mothers say that it was the best? Epidural anaesthesia is a type of regional anaesthesia which is rapidly increasing in its popularity. Epidural works by blocking nerve conductions from the lower spinal segments, resulting in a decreased sensation in the lower half of the body, while at the same time the mother is still awake and conscious (Fraser & Cooper, 2009). The drug is administered in the lower back, into the epidural space, spec ifically in the lumbar region between lumbar 1 and 4. This is achieved by cautiously inserting a Tuohy needle through the lumbar intervertebral space. Once the epidural space is reached, a catheter is threaded through the needle, which will facilitate the administration of the drug either by bolus top ups or continuous infusion. Once epidural is injected, it will start to exhibit its effect within approximately 20 minutes (Johnson & Taylor, 2011). Indications for using epidural anaesthesia There is no absolute indication for opting for epidural anaesthesia, however clinical instances may include: Maternal request: mothers now acknowledge the fact that they can give birth with the least possible amount of pain. Today the majority of parents already have a plan in mind of what they wish and request for their birth experience. Having ongoing accessibility to internet encourages parents to search for types of pain relief, allowing them to make their own choices of what they think is bes t for them. Upon searching and from what they hear from other mothers, they are actually believing that epidural is one of the best choices of pain relief medication (Johnson & Taylor, 2011). Pain relief: prolonged labour can be very tiring and stressful for the mother. Having an epidural can help in reducing the continuous stress of contractions and can possibly help the mother to relax, making her able to conserve energy for later use during the active phase of the second stage of labour (Johnson & Taylor, 2011). Hypotension: epidural has the potential to lower down the blood pressure. This can be used as an advantage for women who suffer from high blood pressure. Thus this anaesthesia can possibly stabilise the blood pressure during labour, aiming to reduce complications (Johnson & Taylor, 2011). Preterm labour: epidural aims to decrease the sensation of powerful contractions and so can be opted for to possibly lower the desire to push during a preterm labour. Use of such anaesth esia depends on the specific condition of the mother and the baby (Johnson & Taylor, 2011). Side effects of epidural anaesthesia on the mother Opting for an epidural can deliver a good experience amongst many women. Mothers are able to rest and relax from the painful contractions while at the same time they are awake and conscious. However, opting for this anaesthesia is very likely to be the beginning of a ‘cascade of interventions’. This means that birth can be transformed into a very medicalised experience, ending up with the mother feeling that she has lost control over her own birth experience. In fact, the World Health Organization states that, â€Å"epidural analgesia is one of the most striking examples of the medicalisation of normal birth, transforming a physiological event into a medical procedure.†

Visual Art Research Assignment and research essay

Visual Art Research Assignment and research - Essay Example 2). However, these art forms possess notable differences because their purposes and intentions lack the modernist expectations in terms of characteristics and traits that guide their architectural make. Despite the current similarities and differences, Villa Savoye and teapot have played a significant role in defining visual practice especially when finding an attachment with modernist concepts such as functionalism and formalism. Le Corbusier’s Villa Savoye and Marianne Brandt’s Teapot have significant influence in the domain of visual art particularly in the promotion of the modernist concept. This is through following the procedural expectations of form follows function essential in exposing the indicative characteristics and traits symbolic with modernism in art. For instance, Le Corbusier’s Villa Savoye is attached to the modernist concept in terms of form follows function through its magnificent five-point architecture that represents the overall impression of architecture in the context of meeting global standards (Butterworth 2013, p. 2). Additionally, the cost and concern associated with Le Corbusier’s Savoye is associated with the architectural changes found in the shape of the building in regards to the form follows function principle. In other words, the Villa, according to Savoye, had to attain certain goals and objectives in his immediate society such as accommodating the Jews and acting as a historical French monument in the specifically in 1965. However, Marianne Brandt’s Teapot has interesting traits that differ with those of Le Corbusier’s Villa Savoye. Functionalism, for example, is infused into the German’s art with concentration of modernist concepts in the overall display of the teapot such as Bauhaus style and integration of the tea infuser to meet the form follows function principle. Consequently, in the

The company is considering investing in one of th - Essay Example This paper will seek to analyze the political, economic, cultural and ethical risks that might affect Asda’s expansion into an Asean member state particularly Philippines. The paper will also identify and evaluate business opportunities in this country. Political analysis Asda is a high street supermarket located in Britain retailing a large variety of food products and may deliver at a customer’s doorstep upon an online order (Oxford Business Group, 2009:26). This company is planning to expand its investment prospects into Philippines as part of its long-term investment plans and looking into this country’s political system can help the business consultant understand the kind of risks or opportunities that the company should expect to face (Schwab, 2011:46). Generally, political stability and the system of governance of a country act as a substantial factor of consideration at times when a firm is planning to invest internationally (Hill, 2011:70). This is so be cause, every country in this world maintains unique and/or different political and economic systems pointing out that when doing business in any overseas country; it is advisable that you be familiar with that country’s market availability and its leadership structure (Cavusgil, Knight and Tiesenberger, 2011:49). The Philippines’ political system is not that complex, but for a British food retailer like Asda, changing its structure to accommodate certain rules and regulations is necessary (Daniels, Radebaugh and Sullivan, 2011:89). The Philippines’ political system is a structured framework constituting a presidential, democratic and representative republic, where the president is both the head of government and the head of state within a system characterized by pluri-form multi-party (Menipaz and Menipaz, 2007:84). Reliable sources establish that different political systems influence the functioning of a business. Philippines have a transitional business enviro nment where the political structure allows for international investment. Since 1986 when Corazon Aquino took over as the president of Philippines, the country formulated its political system with constitutional amendments being the first to change (Schwab, 2011:62). The country’s political administration system has three bodies, which consist of the judiciary, executive and the legislative branch. It has other administrative divisions that facilitate the proper administration of the cities, municipalities and barangayas among other regions. Despite a bit of political turmoil at times, there is no surmountable business pressure or threat posed by these issues (Oxford Business Group, 2009:50). Adequately, the people of Philippines are peaceful and they have a strong liking for investors from the west a particularly in such countries as Britain and the United States (Menipaz and Menipaz, 2007:106). Thus, Asda is at a considerable position to expand its food retailing services in to the Philippines since the political system of this country allows for favourable working conditions. Bearing in mind that political issues erupt at any given time, Asda should prepare for such risks in the

It also aims to develop new product brands and enhance its current brand portfolio. Its core competencies include innovation, brand-building, go-to-market capabilities, scale, and consumer understanding. Among the company’s strengths are its strong R&D focus, market leadership, product portfolio diversification, and strong cash position. However, it has experienced increasing incidences of product recalls, high product prices that have caused a decline in sales volume, and a loss in market share. The company expects to recover, however, by widening its customer base and increasing its worldwide market share by advancing more aggressively into emerging markets. It will realize this goal through three initiatives, namely integration, simplification, and digitization. Eventually, it expects to res ume its former positive market growth. Unilever is a global leader in the manufacture and distribution of fast moving consumer goods. Its portfolio includes some of the best known brands in the world, in foods, home care, and personal care. The company’s forerunner was founded in the late 19th century by William Hesketh Lever, but assumed the name Unilever in 1930 when it merged with other consumer goods companies that had likewise been in existence before the turn of the century. It turned global in the sixties, and attained market leadership in the eighties which it maintains to the present. The firm has manufacturing facilities worldwide, and serves a broad cross-section of the market since its products target customers of all walks of life. Among its core competencies are the ability to conceptualize products, its global logistics network, its scientific research in nutrition, and the ability to communicate and influence public behaviour. Its strengths include a strong br and portfolio, diversified revenue streams, and strong focus on R&D and sustainability. It has a problem, however, in maintaining its sales and profitability performance which have constantly declined in the three years covering 2007 to 2009, indicating that it has a particular vulnerability to the current economic recession. This is attributed to intense competition, rising inflation and reduced consumer demand. The company foresees opportunities for growth in emerging markets and chances to enhance its product portfolio by making some select acquisitions. The firm intends to divest some of its non-core business activities and concentrate on its principal product lines. In the immediate future, it aims to double the size of its business while reducing its impact on the

Family Culture and Tradition - Essay Example ctivities like chores, hobbies or classes that may be associated with the opposite gender and being treated as equals no matter what age or gender have inculcated in all of us strong values that we carry out in our own lives as adults. One tradition we have is sticking to a daily routine as much as we can. I clearly remember, at 6:00 every weekday morning, alarm clocks ring in our bedrooms. As my siblings and I come down to the kitchen, dressed for school, we see our mother busily preparing breakfast for all of us. Like in any other family, this is the time when everyone is in a hurry as we race around the house to get what we need for school. Our parents, on the other hand, prepare for work. Our father drops us off in school before going to the office. Our mother is left at home as she cleans up the mess we have left behind before she herself goes to work. We all have our own different schedules during the day. After school, my siblings and I proceed to our own activities – ballet, art class, violin lesson and karate class. We all have a full day before assembling back home when we arrive at different times. We children rest in front of the television or take a nap in our rooms, then do our chores and homework. We take turns helping out in the kitchen as our parents prepare dinner. Even our parents take turns cooking dinner with Mom cooking on Mondays, Wednesdays and Fridays and Dad cooking on Tuesdays and Thursdays. On weekends, we all pitch in cooking our meals or eat out. We usually have dinner together at 7:30. At the dinner table, everyone shares what happened to them during the day. Another special tradition we have at the dinner table is talking about our ‘up’ times and our ‘down’ times referring to the good and bad things that happened to us during the day. Sometimes, our talks are serious, but most of the time, we laugh and have fun with each other’s company. The dinner conversations we have keep us all updated with each other’s lives. I

Facebook and Events Management - Essay Example To answer the above question, the researcher can go to either quantitative research, qualitative or the mixture of both researches. The patterns of these methodologies are quite different from each other (Creswell, 2003). One of the possible methods for the researcher to conduct this research is Quantitative research approach. Quantitative research focuses on the numerical data or the data which can be converted into numeric form (Sekaran, 2006). Using this technique, primary and secondary data could be collected through various sources (Stewart, 1993). Here secondary data would include the past facts and figures regarding the uses of facebook by marketers for promoting their events. For that purpose, the researcher can collect the data through past researches available in local and online libraries. The data might also be taken directly by the Data collection organizations such as Gallup and AC Nielsen. The researcher can collect the relevant data by these organizations at a minimal cost. In addition to that, various other authentic websites are available which can provide the relevant figures for our research. Moreover, the researcher can also collect secondary data using Newspaper, magazines and other similar periodicals. The primary data can be collected with the help of different data collection tools like questionnaires or surveys. This method would project the number of marketers who will be promoting their events using facebook. However the method is totally based on the past growth rates and does not account the current attitudes and behaviors of marketers towards facebook. For instance, the marketers want new features in the facebook which further help them to promote upcoming events quickly to a large number of people. The method is unable to consider other factors which could impact event managers in using facebook in future. Moreover, the researcher would be objectively separated by the research using this method (Saunders, Thornhill, and Lewis, 20 09). Qualitative Approach: Another method to conduct this research is Qualitative method. The Qualitative method is closer with the subject matter of the research. This method is used to find people’s experience, belief, behaviors, and attitudes (Patton, 2002). In qualitative approach, again, the data can be gathered either through the primary sources of secondary sources. The qualitative approach is appropriate to get more insights and detailed findings about the research topic being investigated. The qualitative method is related with all the qualitative aspects of research. It does not focus on the actual past data about the use of facebook by marketers. The method is useful in determining the past attitude, experience, behavior and future expectation of the marketers towards facebook. The researcher, using this method, could find out the future aspect of the facebook but would be unable to accurately predict the accumulative trend of marketers for promoting events using f acebook. Mixed Approach: The mixed approach is the combination of both qualitative as well as quantitative research. This method is useful when researcher wants to cover all aspects of the research (Maylor and Blackman, 2005). The method using quantitative technique will predict the future growth of the facebook by marketers who will be interested in promoting events using facebook. On the other hand, the qualitative technique will help to the attitudes, experience and behavior of the marketers towards face. It further explores the future need of the marketers to promote their events through facebook. Selected Approach: The researcher is interested to conduct its research through Mixed Approach. This approach will cover all the aspects of the

Principle Of Economics Essay Example | Topics and Well Written Essays - 2000 words

Principle Of Economics - Essay Example As stated in Sloman & et. al. (2012), various policymakers and economists use GDP as the measure of economic well-being. Countries are also often graded according to their GDP values in order to decode their economic development in comparison to other economies in the global network (Sloman & et. al., 2012). However, an in-depth understanding to the concept reveals that economists cannot or most justifiably should not focus only on measuring GDP when quantifying the progress of an economy. In other words, there are certain limitations possessed by the concept of evaluating national progress or development depending exclusively on GDP. For instance, GDP has often been criticised to lack in measuring the outputs of all services as well as goods. As a result, the values of few goods as well as services go unrecorded; thus, understating the nation’s economic growth. There are mainly two reasons for GDP to lack in recording goods as well as services. For example, when people tend t o perform their own labour work without involving a third party, the manpower invested or otherwise marketed is not recorded in GDP statics. Illustratively, if parents hire a babysitter for their baby, the service cost is counted as the part of GDP; but, if the parents decide to stay back at home and deliver their services to take care of their baby, the countable opportunity cost of hiring a professional is not considered as the part of the GDP. At the national level, hen similar attributes remain uncounted or ignored to be measured appropriately, the national activities remain understated and the true value of economic production becomes erroneous (Sloman & et. al, 2012). Similarly, GDP calculation procedure also does not take into account the currency flow generated through illegal trading that is commonly attributed as ‘underground economy’. Underground economy specifically comprises of illegal and undeclared transactions. The transaction could be illegal in the for ms of drugs trading, prostitution and smuggling among others. Again, the transaction can be stated as undeclared only in the sense that they are not exposed for the tax purpose and hence, remain unidentified in the GDP calculation procedure (Sloman & et. al., 2012). It is in this context that GDP lacks accounting for intangible variables sourced within the nation to ensure the well-being such as health, happiness, and woes. It also does not include environmental impacts of production functions practiced within the economy, additionally ignoring the unequal distribution of health (Sloman & et. al., 2012). Notably, one major problem faced by economists when measuring well-being or similar intangible variables by using GDP is that it does not include population of a nation into an account. If these variables are taken into account, countries like India and China, those have greater volume of population, shall be better off in comparison to Australia, which is much advanced than the men tioned nations in terms of technology, infrastructure and other production function variables. Again, as per the common principles of GDP, when the production increases it may be attributed to the technological advancement. On the contrary,

Effects of Pollution in China Essay Example for Free

Effects of Pollution in China Essay In the last two decades, the air pollution in China has increased substantially. The lack of good air quality is especially prominent in the more urban, industrialized areas of China. Environment Minister Zhou Shengxian warned, â€Å"If China meant to quadruple the size of its economy over 20 years without more damage, it would have to become more efficient in resource use. Otherwise, there would be a painful price to pay† (BBC News). The topic of air pollution is not a new concern to the world; however, the effects of air pollution, especially to the hundred of thousands of people directly or indirectly harmed by the side effects of â€Å"bad air,† should be of grave concern. According to the Ministry of Health, air pollution has made cancer the leading cost of death in China. Air pollution not only affects the people, but also the quality of fresh water, produce, and other natural resources. These kinds of environmental outcomes may seem erratic in other countries but unfortunately, it has become the norm in China. In fact, air pollution in China since the 1980’s has gotten so bad that many of the industrialized areas in Beijing and Shanghai rarely see the sun but rather clouds of smoke and fog. China, with its infamous reputation of becoming a global economic powerhouse, is ironically becoming its own downfall. In the midst of their tremendous economic and industrial growth, the energy outputs to support this growth are reaching an all-time high which means there is more residue of coal and fuel burning released in the atmosphere. In order to understand the extent of pollution in China, one must understand the environmental, social, and political aspects of it. Currently, China is the leading nation in terms of population. Even though China has approximately 1. 3 billion people living in its territory, the dangerous effects that pollution has taken upon the population is still of high concern although many people and government officials choose to not talk about it in order to not cause more burden on the already stressed country. According to the World’s Resource Institute, â€Å"respiratory disease is the number one cause of death in China† (World’s Resources Institute). In some regions, especially the major industrial zones in Hebei Province, rates of chronic lung disease are at least five times higher than the rest of the country. Even the women who do not smoke cigarettes and are living around those areas have the highest rates of lung cancer globally that pertains to the population of women who do not smoke (World’s Resources Institute). It is estimated that annual premature deaths attributable to outdoor air pollution were likely to reach 380,000 in 2010 and 550,000 in 2020 (BBC News). With these potential outcomes that are doubling every decade, China will face even more problems if these environmental issues are not dealt with now. In addition to air population, there is also the concern of water pollution which coincides with the big cycle of environmental distress. In addition, many people who live near concentrated areas of pollution do not know how to protect themselves well because they are unaware of the long term effects of inhaling the air and drinking the water. Nearly half of China’s population consumes drinking water contaminated with animal and human waste and acidic rain and erosion. While there has been an overall decline in mortality from infectious diseases, diarrheal diseases and viral hepatitis, both associated with fecal pollution of water, are the leading infectious diseases in China (World’s Resources Institute). Because of contaminated, polluted water, China has the highest liver and stomach cancer deaths in the world. While the government is preoccupied with wanting to censor all this preventable chaos, many more people are becoming ill and dying from the lack of clean resources. Water pollution has become an intricate part of the problem as well. Many of the main rivers flowing through China have been the target for dumpsites for years. Because of its mass and distance, many people do not think twice when they dump their small amount of trash or waste inside the water; however, if twenty thousand other people are having the same exact justification, then it now becomes an environmental safety hazard as well as a social problem. As a result, it is estimated that three-quarters of the rivers running through Chinese cities are so polluted that they cannot be used for drinking or fishing. Even the infamous Yellow River is suffering from man-made environmental problems. Once the countrys second biggest source of fresh water, the river is now so polluted that almost 70% is hazardous to drink; moreover, because the river has been the target for over-exploitation for many years, the water tends to dry up before it reaches the sea for almost a third of the year. According to the World Health Organization, reports estimate that diseases triggered by indoor and outdoor air pollution kill 656,000 Chinese citizens each year and polluted drinking water kills another 95,600 (Platt). The majority of the air pollution in China is generated by the burning of coal and fuel oil in order to generate electric power. They do not have that much hydropower, power that comes from the energy of massive moving water, to help with demand and supply and, therefore, rely on the burning of coal. Coal is a natural resource that is abundant in amount but requires a lot of manpower and miners to obtain it every year. Because of its population and carrying capacity, China burns more coal to produce electricity than the U. S. , Europe and Japan combined. Air pollution and acid rain, which comes from the coal residue evaporating in the form of smoke into the atmosphere, is killing people. In addition to chemical and industrial factories producing all this dirtiness into the air, vehicles of transportation also add to this pollution epidemic. In the 1990s, the number of vehicles on roads increased very rapidly, especially in medium-sized and large cities. In Beijing, the number of vehicles increased by a factor of 4, from 0. 5 million in 1990 to 2 million in 2002. In addition, the emission factor, the amount of pollution emitted by one car, in China is much higher than in developed countries because China has much lower emissions standards for automobiles (The Chinese Academy). Thus, the drastic rise in the number of vehicles and rapid development of industries in cities has led to worsening air quality, particularly higher concentrations of nitrogen oxides. The burning of poor quality fuel only adds to urban air pollution. Considering the amounts of traffic that the more urban, centralized cities deal with on a constant basis, the amount of fuel being burned into the atmosphere is reaching tremendous heights. Over the years, the government had implemented their own ways of dealing with the pollution problem as well as progressing social development. Embarrassed by the repercussions of industrialization and urbanization, China’s environmental agency insisted that the health statistics be removed from the published version of media reports because the government did not wish to cause social instability. According to Spiegel Online International, in 2007 the Chinese government put pressure on the World Bank to take potentially damaging statistics out of a report on pollution in China (Spiegel Online International). Reportedly, the World Bank reluctantly agreed to the demand of the Chinese government and this report about pollution was never published. Many people did not believe the Chinese government undergone such secretive endeavors to â€Å"protect them but rather it was just the Communist’s instinctive response to every case of bad news – to cover it as much as possible. The Chinese government often has had a hard time prioritizing pressing issues at hand and, therefore, chooses to suppress it until the issue starts developing more and then reaches the attention of foreign countries. This kind of pattern has affected the Chinese government for many years now because of its lack of aggression towards personal, current issues. In terms of the environmental issues, China’s model of pollution compared to that of the United States and Europe is worse because the density of its population is greater and people do not know how to protect themselves properly from the essential tools of life, water and air. Because of China’s reputation as being one of the leading nations in fast economic growth, the government places economic growth before any other problem the nation might have. Some may say, the country is addicted to fast growth and instances of progression. Having a strong, solid economy would place China on the map as a great superpower and can very well earn them the respect and recognition from every other nation. If China starts to slow down their industrial development and economic growth at all, the effects would be social instability, the potential to lose foreign business and trading partners, and takes away China’s hard-earned reputation. Slowing down production to solve such insignificant problems may be a stretch for the Chinese government; however, the threat of pollution is very much real and staggering, which in the long run, would affect the economy in a negative way. With the amount of health-related issues due to the environment, health care costs have climbed sharply. The lack of clean water has affected the farming and crop industry tremendously. The amounts of high energy-dependent industries create greater need for imported coal and fuel; therefore, the environmental problems gradually get harder and more expensive to address the longer they remain unresolved. According to National Geographic, the rate in which this pollution is harming women and hildren would have a great effect on the next generation of China’s leaders, especially with the many recorded incidents of birth defects and brain damage that pregnant women are inhaling everyday of their lives. The pollution in China is not just a current problem but an issue that can surely affect the future of China extensively. In recent years, the Chinese government have been striving to address these environmental issues and making reforms to reverse some of the effects. The government has set goals in order to reduce the emission of fuel and to conserve energy by reducing the level of energy that industries use as well as slowing down the demand for coals. Taking ideas from the United States, China has set to develop alternative methods of energy such as solar power. Yet most of the government’s targets for energy efficiency, as well as improving air and water quality, have not been reached. Although there are many targets and goals set forth by the government to fix this â€Å"pollution problem,† no real concrete actions has taken effect. China’s lack of fundamental changes towards conservation and energy-efficient ways has resulted in no real progression. China refused to invest a lot of money and tax reforms to reach their supposed targeted goals. Even many bureaucratic leaders and city officials often do not invest their money and efforts into closing down factories and industries because that would hurt their local economies. In a way, the government reflects a dog-eat-dog world where everyone chooses to look out for themselves in order to prosper the most. In attempts to stick to their original goals, China began to explore the idea of the Green G. D. P in the mid 2000’s. The Green G. D. P was â€Å"an effort to create an environmental yardstick for evaluating the performance of every official in China†¦it recalculated gross domestic product, or â€Å"G. D. P. ,† to reflect the cost of pollution† (BBC News). In other words, this was a way to calculate the financial loss that pollution has had on the economy and for the government to adjust their expenditures in such a way to reflect a better G. D. P. However, the calculations for some provinces in China reach staggering amounts that was unrealistic for the Chinese government to adjust because if they did, their growth rate for certain areas would be zero which means the overall economy would decline. Because of the failing numbers of the Green G. D. P for China’s economy, the government pulled out of the project in 2007. The failed success of Green GDP for the Chinese government pushed the progression of environmental friendliness preservation back because of the financial and economic issues that arose from partaking in the Green G. D. P (New York Times). One such issue that China struggles with is realizing that any attempt or unrealistic goal set forth to fix the environment problem will always be met with many obstacles and resistance. Such unfortunate issues are part of the reason why China is reluctant in fixing their environmental problems and plays a role in the still on-going pollution issue today. In 2011, Toyota Motor announced that they will be making low-emission cars in China. Because China has the biggest market for cars, Toyota Motor wanted to get into that market in an environmentally friendly way. Along with having the biggest market for cars, China also has the biggest market for pollution. China was keen on welcoming the foreign aid of car expenditures to their market because of its emphasis on producing low-emission cars in the country. As China attempts to work towards its pollution problems after many failed efforts, the people foresee this as a positive business venture on both the Japanese and Chinese because it benefits both sides. Japan would create a bigger market for themselves in East Asia and China will be on the road of becoming more green and energy-efficient, a problem that they have been facing for decades. All and all, it is safe to say that China as well as every other country around the world recognizes that the amount of pollution has increased tremendously. China has played a huge part in the matter because of its massive industrialization and urbanization that attributes to their fast economic growth. Although there are many Chinese officials and leaders out there who fail to see the correlation between air pollution and long-term health and social effects, the growth of air pollution is not going away. Although there are very few studies attributing the socio-economic class, population size, and demographics to the growth of air pollution, the presence of air pollution affects everybody. There is, indeed, a major correlation between air pollution and increased mortality; therefore, China strived to undergo many environmental-friendly programs. In short, there is sufficient evidence that exposure to outdoor air pollution is a health hazard in China. The importance of these increased health risks is greater than in developed countries because air pollution in China is at much higher levels and because the Chinese population accounts for more than one-fourth of the worlds total population. Future research will need to clarify the lifetime course of air pollution effects, examine the relevance of long-term exposures, understand alternative methods, and finding correlations between air pollution and health hazards for the Chinese population. Presently, Chinese needs to find a way to efficiently reduce pollution and increase air quality and find a way for industries to be properly monitored. This will enable the people and the Chinese government to be aware of the trends and consequences of air pollution, so they can determine how to remedy the situation in the future.

A microscope: An overview

A microscope: An overview 1. Introduction A microscope is an instrument used to investigate tiny objects which cannot be seen by naked eyes. There exist three types of microscopes which are optical microscopes, electron microscopes, and scanning probe microscopes. (1) Six types of microscopes talked in this report are reflected and transmitted light microscope, scanning electron microscopes (SEM), transmission electron microscopes (TEM), focused ion beam (FIB), and atomic force microscope (AFM). 1.1 Reflected light microscopes Reflected light microscope is a type of microscope using visible light and a system of lenses to magnify images of small samples. It is used to examine opaque specimens which will not transmit light and other materials such as ceramics.The reflected light travels through the objective lens, which in this arrangement acts as both a condenser and an objective, and strikes the specimen.It is then reflected off the specimen back up through the objective lens, the head, the eyepieces, and finally to the eye.(2) 1.2 Transmitted light microscope Transmitted light microscope is a type of microscope where the light transmits from a source on the opposite side of the specimen from the objective. Usually the light is passed through a condenser to focus it on the specimen to get very high illumination. (3)After the light passes through the specimen, the image of the specimen goes through the objective lens and to the oculars where the enlarged image is viewed. 1.3 Scanning electron microscope The scanning electron microscope (SEM) is one kind of electron microscope. The SEM utilizes a very fine probing beam of electrons scanning over the specimen to emit a variety of radiations. The signal which is proportional to the amount of radiation leaves an individual point of the sample at any time. The signal obtained from one point will display the information of that point. In practice, the points follow one another with very high speed so that the image of each point becomes an image of a line, and the line move down the screen so rapidly that the naked eye sees a complete image on the computer. SEMs are patterned after reflecting light microscopes and will yield similar information 1.4 Transmission electron microscope A transmission electron microscope (TEM) works much like a slide projector. A projector shines a beam of light through the slide, as the light passes through it is affected by the structures and objects on the slide. These effects result in only certain parts of the light beam being transmitted through certain parts of the slide. This transmitted beam is then projected onto the viewing screen, forming an enlarged image of the slide. TEMs work the same way except that they shine a beam of electrons through the specimen. Whatever part is transmitted is projected onto a screen for the user to see. TEMs are patterned after transmission light microscopes and will yield similar information. 1.5 Focused ion beam A focused ion beam system (FIB) is a relatively new tool that has a high degree of analogy with a focused electron beam system such as a scanning electron microscope or a transmission electron microscope. In SEM and TEM the electron beam is directed towards the sample generating signals that are used to create high magnification images of the sample. The major difference with a focused ion beam system is the use of a different particle to create the primary beam that interacts with the sample. A highly focused ion beam is used instead of electrons in FIB. As the beam scans the surface of the sample, a highly magnified image is created, which allows the system operator to view the samples microscopic features clearly. 1.6 Atomic force microscope The AFM is one of the foremost tools for imaging, measuring and manipulating matter at the nanoscale. The information is gathered by feeling the surface with a mechanical probe. To achieve atomic scale resolution, a sharp stylus (radius ~1-2 nm) attached to a cantilever is used in the AFM to scan an object point by point and contouring it while a constant small force is applied to the stylus. Piezoelectric elements that facilitate tiny but accurate and precise movements enable the very precise scanning. (4) 2. Study of comparison among six kinds of microscopes 2.1 Optical microscopes Optical microscopes, which use visible wavelengths of light, are the simplest and most used. Both transmitted light microscopy and reflected light microscopy need low energy and the microscope itself is much cheaper and smaller than electron microscopes. Compared to electron microscopes, the optical microscopes have another advantage that the image obtained from them is in color. Comparing to reflected light microscope, the transmitted light microscope only works on light transparent specimens but not metal, ceramics and some polymers such as rubber. However sample preparation of transmitted light microscope is relatively complicated. As it requires sample thin enough for the light to go through. This can be done by using a microtome to slice at lower temperature; as well the distortion of the section due to the sample preparation is a problem for observing. (5) 2.2 SEM The SEM has allowed researchers to examine a much bigger variety of specimens no matter it is bulk or thin layer. The scanning electron microscope has many advantages over optical microscopes.The SEM has a large depth of field, which allows more of a specimen to be in focus at one time.The SEM has much higher resolution (~1-5nm). (5)Because the SEM uses electromagnets rather than lenses, much more control in the degree of magnification can be done.All of these advantages, as well as the actual strikingly clear images, make the scanning electron microscope one of the most useful instruments in research today. However, materials that can be examined in the SEM must be vacuum compatible, clean and electrically conducting such as metal. But for non-conducting materials such as ceramic and polymers, gold or carbon coating on the surface of the sample is essential. 2.3 TEM TEM is a technology using a high energy (80-200kV) beam of electrons to transmit through an ultra thin specimen (50-200nm). High resolution (~0.2nm) is the most significant advantage of TEM. (5) However, there are a number of drawbacks to the TEM technique. Many materials require extensive sample preparation to produce a sample thin enough to be electron transparent, which makes TEM analysis a relatively time consuming process. The structure of the sample may be changed during the preparation process. Also the field of view is relatively small, which leads to the region analyzed may not be characteristic of the whole sample. There is potential that the sample may be damaged by the electron beam, particularly in the case of biological materials. 2.4 FIB FIB is usually used to examine metal surfaces. If the sample is non-conductive, a low energy electron flood gun can be used to provide charge neutralization. FIB is inherently destructive to the specimen because when the high-energy gallium ions strike the sample, they will sputter atoms from the surface. Ga atoms will also be implanted into the top few nanometers of the surface making the surface amorphous. (6) These limitations produce noticeable effects when using techniques such as high-resolution lattice imaging TEM or electron energy loss spectroscopy. 2.5 AFM The AFM is a very high-resolution type of scanning probe microscope, with demonstrated resolution of fractions of 1 nm. (4) AFM provides a true three-dimensional surface profile. Additionally, samples viewed by AFM do not require any special treatments such as coating. Most AFM modes can work perfectly in air or even a liquid environment without a need of vacuum. This makes it possible to study not only metal, ceramic, polymer but also biological macromolecules and even living organisms. In principle, AFM can provide higher resolution than SEM. It has been shown to give true atomic resolution in ultra-high vacuum and in liquid environments. High resolution AFM is comparable in resolution to TEM. A disadvantage of AFM compared with the scanning electron microscope (SEM) is the image size. The AFM can only image a maximum height on the order of 10-20 micrometers and a maximum scanning area of around 150 by 150 micrometers. (4) Another inconvenience is that the AFM could not scan images as fast as an SEM, requiring several minutes for a typical scan, while a SEM is capable of scanning at near real-time after the chamber is evacuated. The relatively slow rate of scanning during AFM imaging often leads to thermal drift in the image making the AFM microscope less suited for measuring accurate distances between topographical features on the image. (4) 2.6 Competition 3. Example of applications 3.1 Reflected light microscope Normally, reflected light microscope is used to image metal, ceramic and rubber. Thats the reason why it is also called metallurgical microscope. Nowadays it becomes a fast growing interest; especially in regard to its increasing usefulness in the fluorescence microscopy as well as the rapidly growing semiconductor industry had also led to an increase in the use of reflected light microscopes. (7) 3.2 Transmitted light microscope Polymers can commonly be looked at under the transmitted light microscope, because most of them are transparent or translucent. It can also analyze cell slices obtained from organism. Most of the lab can afford a transmitted light microscope since it is relatively cheap. 3.3 SEM About any scientific field can use an SEM as a research tool. It can be used to look at the crystalline structures of chemical compounds and how their bonds form. A scanning electron microscope is especially useful for looking at the surfaces of materials at an atomic level. 3.4 TEM TEM can do diffraction analysis of small areas by selected area diffraction. High resolution x-ray microanalysis and analysis of crystal defects such as dislocations, stacking faults using diffraction contrast can also be done by using TEM. Another important application is it can image lattice of crystalline materials. (8) 3.5 FIB FIB can be used as Ion beam imaging. The FIB also offers the ability to perform nanopatterning and micromachining respectively, and by instructing the machine to add or remove pertinent features, operator can design and prototype a new micro or nanostructure, modify integrated circuits and cross section specific features to allow failure analysis even in the 3D (TEM sample preparation). FIB is also used for Secondary ion mass spectrometry (SIMS). (7) The ejected secondary ions are collected and analyzed after the surface of the specimen has been sputtered with a primary focused ion beam. 3.6 AFM The atomic force microscope (AFM) is one of the most powerful tools for determining the surface topography of native biomolecules at subnanometer resolution. AFM allows biomolecules to be imaged not only under physiological conditions, but also while biological processes are at work. The AFM can also provide insight into the binding properties of biological systems. 4. Summary Characteristics of six different types of microscopes are compared in this article, including sample preparation and technique limitations. Each one has its advantage and disadvantage, so it is necessary to consider comprehensively before choosing, for example, the type of the material, needed information, vacuum compatible, conductivity and sample preparation, etc. References Microscopy and Analysis.

If You Want to View Paradise When the sugar cane burned a thick pillar of black smoke twisted and grew up from the fields. The beanstalk of cloud was seen from anywhere on the island and for an afternoon everyone stopped their chores, their cars, their machines to exhale at the desecrating monster. The fire lifted soil, plant debris, worker's gloves and t-shirts forgotten in the fields, insects and rats, children forgotten in the fields, all charred to ash, into the air, stirred it up and threw it back to earth to be interpreted by a more creative voodoo. Cane ash cycloned up in the pillar and blew onto nearby communities with the tradewinds. Curled black ash rained down on my brother and me playing basketball in the driveway. The ash, light, tossed in the wind, collected curled in corners like loose pubic hair. The farmers burned the cane purposefully. They followed the flame, directing it to burn row after row. Late into the night they followed the fire in a semi-circle on the upwind side wearing Hula Bowl t-shirts around their faces like bandits to filter the smoke. Train robbers trying to control the steam locomotive with shovels. Trains have a tendency to run away. The fire husked the cane for them and though it burned a portion of the precious sugar it also burned the glass hairs along the stalk that itched skin and throats for days. The cane fields spread in rows like radio waves echoing out from the base of the Waianai mountain range. On these mountains, closer the peaks at the topmost corner, was a preserve, a deathbed for the last pristine area on the island. Here the rarities mingled in an elite cocktail party for the terminally ill. The Ohia Lehua rooted shallow on the cliffsides, its wood trunk dry like beach wood and its blossoms a blood red exploding out like firecrackers from light green dime shaped leaves. Ala ala wai nui crawled out of holes in boulders. It is called a succulent, its leaves absorb water and are thick and peach fuzzed for it. It is strong enough to break rocks but can not conquer a field of pili grass. The Manono's leaves come out two at a time, opposite each other on the same node. They look like cho cho lips, fat lips, puckering up. They are not plants that grow together supporting and encouraging one another to grow.

The Witch Of Blackbied Pond :: essays research papers

The Witch of Blackbird Pond   Ã‚  Ã‚  Ã‚  Ã‚  Kit Tyler, the main character of Elizabeth George Spear's book, The Witch of Blackbird Pond, must leave her carefree life in tropical Barbados, and go and live in Connecticut. She learns that playing is what is to life, but hard work. She learns that if people do not know you, that they pre judge you. She also learns that if you don't live up to the Puritan life style, that they will look down at you. Kit must learn to cope, and learn from all these changes in her life.   Ã‚  Ã‚  Ã‚  Ã‚  First of all her grandfather dies, which leaves her as an orphan.

When she arrives at her relative's house, she is amazed how small in was compared to the house she lived in on Barbados.   Ã‚  Ã‚  Ã‚  Ã‚  Secondly, she goes to church. In Barbados her grandfather never stressed church as being important, so this was a new experience. When they started to sit down, the family separated into two groups, the men would go to the left, while the women sat to the right of the aisles. Then the Priest would talk about that Sunday's lesson. Then they went home, and had Sunday's dinner. Then her uncle would read out of the Bible. Then they would go to bed.   Ã‚  Ã‚  Ã‚  Ã‚  Thirdly, the people never like people that never followed the rules. One day when Kit was working in the field, see was told a story of an old Quaker woman that lived by Blackbird Pond.

When see arrived, she saw a poor old women in a tiny little house, and then Kit started to help her. When the children of the town got sick, the town people went to get to old women, and make her stand trial for supposedly casting a spell.

Darkness from Within: Analyzing Hawthorne’s Essay

Nathaniel Hawthorne’s â€Å"Young Goodman Brown† is a chilling exploration of how a man could project upon others his own darkness. Through a pact with the Devil, Goodman Brown becomes obsessed with the supposed sins of the townspeople. Hawthorne utilized many symbolisms to depict how Goodman Brown transformed into â€Å"a stern, a sad, a darkly meditative, a distrustful, if not a desperate man did he become† (91). To use a word descriptive of many people today, Goodman Brown became a cynic. So when he died, the townspeople â€Å"carved no hopeful verse upon his tombstone, for his dying hour was gloom† (92). At the start of the story, Goodman Brown was a naive young man who has just been married. He has a dream in which he sees all the best people in the village, including his wife. Presumably, in his experience with sex in his newly-married state, the sexuality — the human quality — of everyone, including his wife, his parents, his minister, and his teachers, dawns on him in a traumatic way in that he has always been taught by his Puritan teachers that the flesh is sinful. However, Goodman Brown had seen both the best and the worst in human nature. In this process, Goodman loses his â€Å"faith† and his love and chooses to believe the worst. The story did not tell everything as easy because readers are enjoined to assume that Goodman Brown’s former innocence had been derived from ignorance, as knowledge comes to him with so much intensity that he is not able to excuse himself for the ignorance that he had. And he blames everyone else because none of them told him these things before. In short, he wants to have had divine knowledge, and he thus challenges the way of things in every respect. Just by being human, people he sees through his loveless eyes transform into witches. Those who have this loveless view of others have already, ironically, partaken of the devil’s baptism. Like Brown, they forever after will be â€Å"more conscious of the secret guilt of others, both in deed and thought, than they could now be of their own† (91). Reading â€Å"Young Goodman Brown† is a good motivation for examining point of view — the way we see other people. The result is a reversal of roles between good and evil, which is like the reversal that occurred after the hysteria of 1692 whereby the â€Å"witches† were perceived as martyrs and the accusers and condemners were seen as persecutors. Hawthorne is interested in what people’s points of view and judgment tell us about them, so the focus in the discussion of witchcraft is primarily on those who see witchcraft in others. The story is rich in symbolisms thst make up what it lacks in physical descriptions, which contributes to its reader’s puzzlement that more often becomes fear. In the story, we only know that Faith has a â€Å"pretty head† (83); that Goodman Brown is young; that Goody Cloyse is â€Å"a female figure† (85) who cackles; that Martha Carrier is â€Å"a rampant hag† (90); that the crowd in the forest is â€Å"a grave and dark-clad company† (89). The reason why Hawthorne avoids particulars in this story is because the unreality and vagueness increase the nightmarish atmosphere of the story. For instance, why is Faith’s â€Å"pink ribbons† is mentioned five times in all? What is the meaning of the appearance of the ribbons in the woods? It would seem to be a concrete evidence that something bad occurred to her. Fogle (1964, p. 18) suggested otherwise: â€Å"If Goodman Brown is dreaming the ribbon may be taken as part and parcel of his dream. . . This pink ribbon appears in his wife’s hair once more as she meets his on his return to Salem the next morning†. For me, what’s more frightening in Hawthorne’s â€Å"Young Goodman Brown† is not the devil, the witchcraft or even Brown’s solitary walk through the forest at dusk, but it is the contrast between Brown’s innocence and the evil that he comes to learn is hidden in his very own community.

The Return: Midnight Chapter 43

â€Å"Elena?†Stefan said quietly. â€Å"Could you ask me to come in? You have to invite me in if you want to – to talk – â€Å" Invite him in? He was already in – inside her heart. She had told the Guardians that everyone would have to accept Stefan as her boyfriend of almost a year. It didn't matter. In a low voice she said, â€Å"Come in, Stefan.† â€Å"The window's locked from your side, Elena.† Numbly, Elena unlocked the window. The next moment she was encompassed by warm, strong arms in a desperate, fervent embrace. But the moment after that, the arms dropped, leaving her frozen and lonely. â€Å"Stefan? What's wrong?†Her eyes had adapted and by the starlight through the window she could see him hesitating before her. â€Å"I can't – It isn't – It's not me you want,†he said in a rush that sounded as if it came through a constricted throat. â€Å"But I wanted you to know that – that Meredith and Matt are holding Bonnie. Comforting her, I mean. They're al okay and so is Mrs. Flowers. And I thought that you – â€Å" â€Å"They put me to sleep! They said they wouldn't put me to sleep!† â€Å"You fel asleep, lo – Elena. While we were waiting for them to send us home. We al watched over you: Bonnie, Sage, and I.†He was Stillspeaking in that formal, unusual tone. â€Å"But I thought – Well, that you might want to talk tonight, too. Before I – I left.†He put a finger up to stop his lip from shaking. â€Å"You swore you wouldn't leave me!†Elena cried. â€Å"You promised, not for any reason, not for any length of time, no matter how noble the cause!† â€Å"But – Elena – that was before I understood†¦Ã¢â‚¬  â€Å"You Stilldon't understand! Do you know – â€Å" His hand flew to cover her mouth and he put his lips to her ear. â€Å"Lo – Elena. We're in your house. Your aunt – â€Å" Elena felt her eyes widen, although of course subconsciously she had known this al along. The air of familiarity. This bed – it was her bed, and the spread was her beloved gold and white bedspread. The obstacles she'd known how to avoid in the dark – the tapping at her window†¦she was home. Like a climber who has negotiated an impossible-seeming section of rock, and almost fal en, Elena felt a tremendous rush of adrenaline. And it was this – or, perhaps, simply the power of the love that flooded through her – that achieved what she had been so clumsily trying to reach. She felt her soul expand and come out of her body. And meet Stefan's. She was appal ed by the hastily swept-away desolation in his spirit, and humbled by the surge of love that flooded every part of him at the touch of her mind. Oh, Stefan. Just – say that – that you can forgive me, that's all. If you forgive me I can live. Maybe you can even be happy with me again – if you just give it a little time. I'm already happy with you. But we have all the time in the world, Stefan reassured her. But she caught the shadow of a dark thought whisked quickly out of the way. He had al the time in the world. She, however†¦ Elena had to choke back a laugh but then clutched at Stefan suddenly. My backpack – did they take it? Where is it? Right beside your nightstand. I can reach it. Do you want it? He reached in the darkness and pul ed up something heavy and rough and none too pleasant-smel ing. Elena thrust one frantic hand inside it while Stillholding on to Stefan with the other. Yes! Oh, Stefan, it's here! He was beginning to suspect – but he only knew when she drew out the bottle labeled Evian Water and held it to her cheek. It was icy cold, although the night was mild and humid. And as it effervesced violently, it glowed in a way that no ordinary water did. I didn't mean to do it, she told Stefan, suddenly worried that he might not like to associate with a thief. At least – not at first. Sage said to get the water from the Fountain of Eternal Youth and Life into bottles. I dug up a big bottle and this little one, and somehow I stashed the smaller one in my backpack – I'd've put the big one in, too, but it didn't fit. And I didn't even think about the little one again until after they took away my Wings and my telepathy. And a good thing, Stefan thought. If they had caught you – oh, my lovely love! His arms squeezed the breath from Elena's lungs. So that's why you were suddenly so eager to leave! â€Å"They took almost everything else supernatural about me,†Elena whispered, placing her lips close to Stefan's ear. â€Å"I have to live with that, and if they'd given me a chance I'd have agreed – for the sake of Fel ‘s Church – if I'd been logical – â€Å"She broke off as she suddenly realized that she had been literal y out of her mind. She'd been worse than a thief. She'd tried to use a lethal attack on a group of – mostly – innocent people. And the worst thing was that a part of her knew that Damon would have understood her madness, while she wasn't sure Stefan ever could. â€Å"But you don't have to change me into – you know,†she began whispering frenetical y again. â€Å"A sip or two of this and I can be with you forever. Forever and – for – forever – Stefan – â€Å"She stopped, trying to get her breath and her mental balance. His hand closed over hers on the cap. â€Å"Elena.† â€Å"I'm not crying. It's because I'm happy. Forever and ever, Stefan. We can be together, just†¦just us two†¦forever.† â€Å"Elena, love.†His hand kept hers from twisting open the bottle. â€Å"It – isn't what you want?† With his other arm, Stefan pul ed her tightly to him. Her head fel forward onto his shoulder and he rested his chin on her hair. â€Å"It's what I want more than anything. I'm†¦dazed, I guess. I have been ever since – â€Å"He stopped and tried again. â€Å"If we have al the time in the world, we have tomorrow,†he said in a voice muffled by hair. â€Å"And tomorrow is time enough for you to start to think it through. There's enough in that bottle for maybe four or five people. You're the one who's going to have to decide who drinks it, love. But not tonight. Tonight is for†¦Ã¢â‚¬  With a sudden rush of joy Elena understood. â€Å"You're talking about – Damon.†Amazing how difficult it was to simply say his name. It almost seemed a violation, and yet†¦ When he could talk – like this – for a moment to me, he told me what he wanted, she sent. Stefan stirred a little in the darkness, but said nothing. Stefan, he only asked for one thing before he†¦went. It was not to be forgotten. That's all. And we're the ones who remember the most. Us and Bonnie. Aloud she added, â€Å"I wil never forget him. And I wil never let anyone else who knew him forget him – for as long as I live.† She knew she'd spoken too loudly, but Stefan didn't try to quiet her. He gave one quick shudder and then held her tightly again, his face buried in her hair. I remember, he sent to her, when Katherine asked him to join her – when we three were in Honoria Fell's crypt. I remember what he said to her. Do you? Elena felt their souls intertwine as they both saw the scene through the other's eyes. Of course, I remember too. Stefan sighed, half-laughing. I remember trying to take care of him later in Florence. He wouldn't behave, wouldn't even Influence the girls he fed on. Another sigh. I think he wanted to get caught at that point. He couldn't even look me in the face and talk about you. I made Bonnie send for you. I made sure she got both of you out here, Elena told him. Her tears had begun to flow again, but slowly – gently. Her eyes were shut and she felt a faint smile come to her lips. Do you know – Stefan's mental voice was startled, astonished – I remember something else! From when I was very young, maybe three or four years old. My father had a terrible temper, especially right after my mother died. And back then, when I was little, and my father was furious and drunk, Damon would deliberately get in between us. He'd say something obnoxious and – well, my father would end up beating him instead of me. I don't know how I could have forgotten about that. I do, Elena thought, remembering how frightened she had been of Damon when he'd first turned human – even though he'd put himself in between her and the vampires who wanted to Discipline her in the Dark Dimension. He had a gift for knowing exactly what to say – how to look – what to do – to get under anyone's skin. She could feel Stefan chuckle faintly, wryly. A gift, was it? Well, I certainly couldn't do it, and I can manage most people, Elena replied softly. Not him, though. Never him. Stefan added, But he was almost always kinder to weak people than to strong ones. He always did have that soft spot for Bonnie†¦ He broke off, as if frightened he'd ventured too near something sacred. But Elena had her bearings now. She was glad, so glad, that in the end Damon had died to save Bonnie. Elena herself needed no more proof of his feelings about her. She would always love Damon, and she would never al ow anything to diminish that love. And, somehow, it seemed fitting that she and Stefan should sit in her old bedroom and speak of what they remembered of Damon in hushed tones. She planned on taking the same thing up with the others tomorrow. When she final y fel asleep in Stefan's arms, it was hours after midnight.

Avatar movie Review Example | Topics and Well Written Essays - 750 words

Avatar - Movie Review Example Anthropology is the scientific research of human beings and their ancestors. â€Å"When his twin brother is killed, disabled ex-Marine Jake Sully is recruited to aid a mining expedition on the distant jungle moon of Pandora as only his DNA will bond with the alien hybrid body, known as an Avatar, which allows humans to breathe the toxic air.The initial impression one gets about the Na’vi aside from their alien trappings, is that they are a primitive race. Primitive is a relativistic term and here it is used to mean that they are technologically backwards compared to the humans who come to Pandora. The Na’vi subsequently faced with the challenge that comes when a tribal community comes into contact with a more technologically advanced civilization. The humans who come to Pandora are there to mine the local minerals to be used back on their home planet. This begs the question, ‘what happened to their home planet?† The Na’vi cultural practices resemble those of other pre technology civilizations. They live in small villages spread throughout the planet. They have developed a form of religion, a system of government and have learned hunting as a source of sustenance. They also have their own language used for communicating with one another, and with the local wildlife using their body language combined with high pitched shouts and clicks.The language is more intuitive more than descriptive. For example when they say â€Å"I see you,† it mostly means that they see into you rather than a visual interpretation of the observed object or individual. Their language is also accompanied with hand signals and movements to emphasize emotions and ideas communicated (Chris, 2012). As history has attested time and time again, when a more technologically advanced civilization comes into contact with what they perceive to be a primitive society, the humans take it upon themselves to â€Å"civilize† the Na’vi. Motive aside, th e impression that what the humans have in terms of technological advancements is I think misguided. The Na’vi are not the one who have bled their home planet dry, and have then travelled halfway across the galaxy in search of the aptly named mineral unobtainium. In the aim of civilizing the natives, the human open school, teach the Na’vi their language, they also try to trade their medicine and food with the Na’vi with the aim of obtaining the unobtainium (Chris, 2012). The Na’vi on the other hand feel that the humans are misguided, and also unsuccessfully try to teach them their way of life until the arrival of Jake Sully. There is a mutual sense of ethnocentrism within the two communities, and whether it is justified is a matter of opinion. The humans feel that their way of life is superior to the Na’vi while the Na’vi feel that their way of life is the only way to live harmoniously with their environment. The Na’vi live in the jung les of Pandora, their main food source is the jungle. They are hunters and gatherers. They also domesticate the local wildlife and use it as a means of transport. They also use the animals to hunt and defend themselves. As with most hunter gatherer communities, prowess in hunting is highly valued and strength greatly affects the individual’s status within the community. They have a sense of brotherhood and oneness with their prey since it is part of them, part of the jungle and thus part of Eywa. They do not needlessly kill their prey and only hunt what they eat. They even go out of their way to reduce instances of confrontation between themselves and the hostile wildlife in the jungle. This
