Multinational corporations and wealthy elites minimize tax burdens so that poor countries are denied tax revenues from each of these sources exceeding in aggregate the current level of foreign aid. Besides this, investment in the rural economy always pays off. Rewards of economic growth are to be spent on payments for the poor and for immunisation. Of equal importance to local communities and individual households is greater power to control their own affairs.  Control Key and Word – Text and Graphics. An infusion of accountability through democracy and individual rights creates the environment in which governments come under pressure to end wasteful practices and corruption. However the removal of agricultural subsidies that protect American and European farmers is needed to create a favorable atmosphere for the real business competition to take place. A fundamental reordering of priorities is the surest remedy for the poor, as indeed it may be for all of us in search of a sustainable future. Plenty of issues call for fundamental reform of global governance. Undoubtedly, some other sectors where developing countries struggle for treatment are trade, investment, intellectual property rights, climate change and energy. It’s a well-known fact that Brazil, China and Vietnam are countries with the greatest success in poverty reduction. Only their governments control key sectors of their economies and show little inclination to relax those restrictions on human rights and democratic freedom. That’s why we need to find another solution of this consequential issue. How to cite Solutions to Global Poverty, Papers

Leading Change Reinventing Organization Development

Question: Describe about the Leading Change for Reinventing Organization Development? Answer: As the saying goes, change is a process of life. For the betterment of life and society, change is inevitable. Every day a new change is incorporated in the life of the people; it can be in the form of technology, organizational change, and change in viewpoint and so on. The following literature review will throw light on the topic of organizational change. The process that leads to the organizational change and how the change affects the life of another individual who are related to the change will be the main topic of discussion in the literature review. Scenario The scenario presented a situation when the British Airways though of implementing certain change in the organization by introducing electronic clocking system. The main aim of the organization is to monitor the attendance of the employees, a better handling of the shift of duty timings and calculate the exact hours of overtime that the employees have worked. However, the employees were not ready to accept the change. According to the employees, it is an intentional approach to manipulating the employees hours of work and change the shift timings so that the managers have to pay less to the employees. As a way to display their dislike in the approach the employees went into a strike, that stopped the operations for 24 hours and the British Airways had to lose as many as 10,000 customers in that stretch of 24 hours. Had the employees given a thought regarding the change implemented by the authorities, the situation might not have arose which resulted in the loss of the company as well as the employees. Review 1 According to Palmer, Dunford, and Akin, any change requires five main points (Palmer, Dunford, and Akin, 2009). The leaders should be able to inject the thought in the mind of the followers that change is normal. Many employees might think change is equal to instability in the organization. It is up to the managers to make them understand that change is a part and parcel of the organization. The commitment of the employees is tested when the organization is bringing a change in the organization. Similarly, when British Airways is bringing a change in the organization it is the cooperation of the employees that the company will need the most which was not provided in the time of need (Burke, 2013). Resistance comes complimentary with change. Though British Airways has faced a lot of resistance from the part of the employees, yet the company should consider the resistance as a good sign for the development of the company. The opposition from the employees is an indication that the work force of the organization is still alive. It is the responsibility of the company to make the employees understand that it is the followers who make the change in the organization and it for the betterment of the workers that the company incorporates various changes in the organization. Hence, the workers should cooperate with the change that has been brought within the organization and work accordingly. Review 2 According to Werkmen, once a company approaches any change and development in the organization, the steps taken by the company should make a certain sense to the employees associated with the change (Werkman, 2010). The main of the article is to make the companies understand sense-making approach towards organizational development. By doing so, the company will be prepared to face the confrontation from the employees. However, it may happen the employees understand the idea behind the changes in the organization and hence, the level of confrontation from the employees may become less (Van de Ven, and Sun, 2011). In the given scenario as well, provided that the British Airways would have made the employees understand idea behind the change and incorporated sense-making approach towards the organizational development, the scenario would not have been as rough as the company has faced. Once the British Airways has incorporated more sense-making actions while bringing the change, the org anization would have been better able to handle the situation which went out of hand due to the long strike and resulted in the huge loss on the part of the company. Identifying the problems Before implementing a change, any organization should gradually bring the change rather than just implementing the change one fine morning. The organization should talk about the advantages and the disadvantages of the change that will be brought in the organization. In addition to this, the organization should talk about how to face the challenges that will arise from the change (Millar, Hind, and Magala, 2012). In this scenario, British Airways has not informed the employees regarding the change that the company is implementing; as a result, British Airways has to face the resistance from the employees. On the other hand, the employees viewed this change as a problem in the way of their work. The employees were not aware of the advantages of the change that will make the operations better and hence they protested against the company regarding the sudden change in the organization (Oakland, and Tanner, 2007). Reflections on the problem It has been seen that the change management applied by the British Airways has been hugely resulted by the employees of the organization. However, this kind of problems could well handled by the organization by educating the employees about the advantages of the following g change that have been introduced in the organization (Brown, and Harvey, 2011). Once the organization has educated the employees about the change in that is coming their way, the employees would have understood the reason behind the change tend the huge opposition would have been stopped as well as the loss that has been generated due to the opposition (Sirkin, Keenan, and Jackson, 2005). From the employees point of view as well, it was not right from the part of the employees to indulge in such an outbreak. The commitment of the employees is tested when the organization is bringing some change. Provided the employees do not support the organization at the time of need, those employees cannot be considered committ ed to the organization; hence, the employees should not expect any commitment from the organization as well.

The Policy of One Child Per Couple in China Death and Birth Rate

Abstract This paper examines the policy of one child per couple in china. This is in regard to the composition of the population of this country. A number of statistics are going to be illustrated and analyzed at length. An important data to be analyzed is the population growth rate data for both males and females in China, from 1985 to 2010.Advertising We will write a custom research paper sample on The Policy of One Child Per Couple in China: Death and Birth Rate specifically for you for only $16.05 $11/page Learn More Another data used is the general population of China. The data used in determining if the population is ageing is the dependency rates. There are three rates in this case, the general, the old (working), and the young (working). The rate of death is incorporated in this examination. Finally, a population pyramid is used to give an illustration of the population of China. Introduction In China, a policy to plan families was introduced dur ing the eighteenth century to rein in on an increasing population. In this policy, citizens of China were enticed into marrying later than they used to. The time for giving birth was also regulated by this policy. According to it, married citizens living in cities were to have only a single child, and those in the rural areas were allowed not more than 2 children (Xinhua News Agency par 2).This policy has been credited with reducing China’s population by millions over the past decade. However, there have been a number of concerns about its effects to the population. One such is the part of the population who are now categorized as old compared to the younger generation. There are now concerns among the authorities who are considering undertaking a policy shift (Xinhua News Agency par 3). Some population parameters that are used include the total number of people in China, rates of deaths and births, the young people, and their dependence on the older generation for sustenance and the older people who are also dependent on others. Since the policy was implemented in 1978, the analysis will include the population data for the period before and after this time. China’s population has grown so fast over time. The rate of growth was highest in the nineteen fifties. The graph below shows a great reduction in this rate in recent times.Advertising Looking for research paper on social sciences?

This has an implication on the sustainability of this population in terms of raising young and energetic individuals who can take over productive roles in the society. This is because women are the ones responsible for conceiving new life. In China, the dependency between different age groups has been varying for the past fifty years. The dependency ratio is calculated from the proportion of the working population. It excludes those dependent on the working population below 15 years and older than 64 years. A total of a hundred working people in the same age bracket are taken for every proportion of dependants. â€Å"This percentage was 78.49 in 1964 8.21 in 2010† (Li p 65). The values that follow are much more comprehensive about the subject from the year nineteen sixty to two thousand and ten for China as provided by the World Bank. From figures given below it can be seen that the general age dependency has been on the decline as from the nineteen sixties. This implies that a good percentage of the country’s population has been incorporated into the countries work force gradually year after year. These are the people who are in the age bracket between fifteen years and sixty four years of age. The reason for this could be the increase in the number of people within this age bracket over time. What cannot be said about this particular dependency is whether it is of the old the young or the old citizens of China. To look at this, it is necessary to look at these two types of age dependency. The statistics in this table, that is figure five which represents the number of old people over the age sixty four years of age shows a particular trend which is that of a gradual increase in the number of old people who are dependent on the people involved in work. This mea ns that these categories of Chinese citizens have increased with time in the past years. The likely cause could be the one child policy of maintaining population growth rate which appears to have influenced a slowdown in the number of young people.Advertising Looking for research paper on social sciences? Let's see if we can help you! Get your first paper with 15% OFF Learn More We cannot however conclusively say this until we look at the trend displayed by the dependency of the young people over the working population of China. Looking at figure six, it can be seen that the young dependency rate for China has been on the decline for the past twenty years. This means that for the past fifty years the number of those less than fifteen years of age in the Chinese population has been decreasing. We can thus say that there has been an increase in the number of people who are above the age of fifteen years in this country over the past year. In the same breath from what has been observed in figure five, we can also say that the number of Chinese citizens above the age of sixty four has increased. These two imply a population that has grown older because of some policy changes Figure eight in the appendix gives the figures for the death rates, the rates of birth and alongside the rate at which the population is growing. Starting with the figures for the birth rat e, it can be seen that save for the first two years, it has been decreasing since 1978. From a high of 18.25 in that year to a low of 12.21 in the year 2004.For the death rate there are slight declines in it, even though the figures are very marginal, decimals actually they are sustained at the rate of six averagely through out. The population growth rate on the other side has shown some amount of decline except for the year 1981. The decline is significant, from a high of twelve in 1978 to a low of 5.87 in the year 2004.A low birth rate over the year’s means that few children are born to replace the existing population. This explains the decrease in population rate over time. Since the death rate is almost constant and also low at the average rate of six it means that more people live to their old age. Finally, an analysis is done to figure out if the population of China is ageing. This achieved by scrutinizing a recent Chinese population pyramid. It can be seen in the figur e seven below. The given figures confirm that majority of the Chinese population are above forty four years old, which is the symptom of an ageing population. Figure seven Source: US Census Bureau. Conclusion The fact finding about China’s population trends indicates a number of things. The first among them is a decline in the rate of growth of the population. The other notable fact is a reduction in the rate at which the young people below the age of fifteen are dependant on the population over the years. Still on dependency, it can be noted that there is an increase in the number of people above the age of sixty four who dependant on the working population. From the country’s population pyramid what is notable is that that the age brackets with the most people are those of people between the ages twenty to twenty four years, thirty five to thirty nine and forty years to forty four. The last two age groups mentioned consist of people who are approaching retirement. Considering the low numbers in children who are five to nine years old and zero to four years, it is important that a reversal in the population growth trend is sought. Works Cited Li, Lillian.

The Principle Of Stare Decisis Example

The Principle Of Stare Decisis Example The Principle Of Stare Decisis – Coursework Example The Principle of Stare Decisis Court adherence according to the legal issues presented is established on the basis of court decisions. The application as evidenced essay demonstrated what the court had already decided on the murder case of Charisse and Lacie. The expectations based on the legal system were to define some level of consistency as explained in the case establishment procedure. Though the murder case appeared complex and based on various facts, Stare decisis explored by preserving some amount of information necessary to project appropriate decisions. Depending on the set of information presented, Payne actions illustrated that the settings made against the evidence projected explore a reconsideration based on facts. (Black, 1979)In the first instance, the malt of liquor which had Payne fingerprints was equally fully based on the existing information. Prior to the murder, there appeared to have been various classes of information that the judges had to dwell on in order t o establish the necessary judgment. Equally enough, the argument was consistent with the various state of information, and the judges were hence at liberty to ignore the stare decsis. The composition of this attempt is based on mistakes making a controversial role play in the entire ruling. Hence adherence to decisive principles involves providing absolute information as per the court establishment. The criminal justice law agencies make a reflection of the law and the constitutional overruns help to provide a justifiable understanding of the effective law judgments. If for example the murder case involving the minor aged 3 presented in the essay appears to be counter-productive then the law considers the latest information and hence presents this before the US Supreme court for interpretation. Court decisions defined in the US Supreme court and expressed as an overturn imply that the system itself is based on the stare decisis decision procedure, widely accepted according to the la w. The aggravation based on the amount of punishment preferred explore the impact of the guilt especially when the evidence is adequate and which would warrant unconditional passage of judgment.

Background check of hiring employee Essay Example for Free

Background check of hiring employee Essay In nowadays, background check of hiring employee is practicing by almost all agencies. Point is that, the skills of the applicant can be, somehow, figured out. It is much more difficult to assess the level of trust, honesty, mental toughness, and loyalty. Reading through chapter 9, and conducting a slight research, my answers to the questions of the given scenario are as follows: 1.Do temporary agencies have a â€Å"duty† to run background checks? If so, did Robert half â€Å"breach that duty?† Why or Why not? According to the law of negligence, temporary agencies should follow the duty policy on background check on pre-employment, in order not to satisfy an element of negligence. In case of Robert Half International Inc., and Fox Associates, Inc., I don’t think, that duty was breached, the company trusted to provided information by Ms. Ross about herself, and she got good recommendations from her former employers. At some extend, it is a background check. 2.The court ruled against Fox Associates. Was the court correct? Do you think Fox should have done its own background check? Why or Why not? I agree with the court decision, that it was determined that duty is not breached, because it happened unknowingly. Even though the company recommended the employee, Fox could do its own background check as well. 3.The fact pattern mentions that Sunbeam suffered similar damages when it failed to do its own background check on Mr. Dunlap, its former CEO. Who was more at fault, Sunbeam or the Executive search agency? In this case, the fault has an Executive search agency more, than Sunbeam, as it its straight duty to check background before approve for hiring. However, Sunbeam is liable for its losses also, because it should request and check the information about hiring employer. 4.Strategically and legally speaking, why do you think the former employers said nothing about Ms. Ross’ history and gave her good recommendations? There could be some reasons: 1). the former employers might feel sympathetic towards Ms. Ross, and they don’t believe that she has stolen any funds; 2) Ms. Ross, indeed a good specialist in her field; and the last 3) The former employers just didn’t tell the truth. 5.Develop one  unique background check policies for your company on employees hired through a search firm or temp agency. The main idea on background check which I’d like to develop, besides gathering information, confirmation of address, criminal records searches, is that pre-employee will answer some â€Å"simple† questions, which will ask him/her the same, but in different manner, and maybe I would add some psychological tests, which will let me know if that employee was capable to do something unethical in his past work experience. Background check of hiring employee. (2017, Feb 12).

Event study for efficient market hypothesis ex dividend data Dissertation

Event study for efficient market hypothesis ex dividend data - Dissertation Example The intention of this study are efficient market hypothesis. The theory ‘efficient market’ was formulated by Eugene Fama in 1970. He described an efficient market as a market where at any point in time, actual prices of individual securities already reflect the effects of information based both on events that have already occurred and on events which, as of now, the market expects to take place in the future. The efficient market prices represent the intrinsic value of the securities. Researchers have developed this hypothesis to be known as the Efficient Market Hypothesis (EMH) which states that the market prices reflect all information known to the public. Market react to any new information available in the market immediately as reflected in stock prices rather than gradually adjust it. This theory is an important concept in the area of understanding equity markets and cost of equity capital. Another important concept in the area of equity markets is that of random wa lk hypothesis. According to this hypothesis, the anticipated price of an asset fluctuates randomly around its expected value. Both the efficient market and random walk hypothesis, it is a futile exercise to try and find overpriced and under-priced assets. This is because, in an efficient market, the assets in the stock market are already reflecting all the available information. There are no future predictions that can be made about how a market will behave. The price of any assets is already a reflection of the best estimates for the expected risk and return of the assets. The suggestion that all the information known about past, present and future events is reflected in the current market prices means that the financial analysts are snake oil salesmen. This is why the EMH is such a controversial hypothesis. However, in an inefficient market, investors can identify miss-priced assets. Identifying the same can enable an investor to achieve gains (Rutterford, 1993). Because of these reasons, these hypotheses provide a solid theoretical and predictive model about the operations of the financial markets and influence more people to invest in stock market (Will, 2006). Types of Market Efficiency There are three primary categorization of EMH given by Fama (1970) according to the type of information reflected in the stock price – 1. Weak-form efficiency - Share prices reflect all past information and thus, rules out the possibility of predicting future stock prices on the basis of past

FirstGroup plc Essay Example | Topics and Well Written Essays - 1000 words

FirstGroup plc - Essay Example As of 2009, the group earned the annualized net profit of around 6 billion pounds, which is a growth of around 31.4% from what the company earned last year. Similarly, this group has remained unaffected by current global economic backdrop, which is an amazing achievement by the company. In the future, the group also wants to maintain its market leader position and wants to expand its operation to the global market. The company wants to develop a new business plan which should not in any way ignore the aspiration of stakeholders. Stakeholders can be any group or an individual that has a stake in the organization's performance. In simple words, any one within or outside the organization who is affected by the decision taken by the business is known as stakeholder. First Group's stakeholders are its shareholders, employees, government, customers and its board of directors. According to Richard Daft, shareholders are those people who own the business and have invested the money in the business.

Similarly, First Group's decisions are also going to affect its employees, in some way or the other. First Group PLC's decision to downsize can result in loss of job for some of these employees. First Group PLC's working policies and pay-rate is another factor that is goi ng to affect the employees. Government might be interest in the decision taken by First Group PLC because if it earns good profit, it will result in revenue for the government in the form of taxes.

Customer will affected by the pricing decisions of First Group PLC. Board of Director will be interested in growth decision of the business because their salaries may be dependent on the size of the business.

(Daft, 1997) Business aim is the future-vision of the business, which can be anything that the business wants to achieve in the future or the reason behind its existence.

Woman in Mind by Alan Ayckbourn Essay Example for Free

Woman in Mind by Alan Ayckbourn Essay How does Ayckbourn present the contrast between Susans fantasy family and her real family in Woman in Mind. Explore the importance of this contrast to the plays central theme. In Woman in Mind Ayckbourn uses Susans creation of an idealistic fantasy family and more importantly the contrast of this perfection with her reality to help portray Susans emotional breakdown to the audience. The role of the fantasy family in this play is to emphasise the unhappiness and emotional turmoil in Susan real world as they generally appear at a point where Susan is in a particularly distressing situation with her real family. One of the ways in which Ayckbourn presents the contrast between the two families is with the use of the differing appearances. For example when the audience meets the fantasy family for the first time they are presented as (tall, good looking, athletic), and Lucys clothing is (fresh, summery, rather timeless). This is a complete contrast to the way in which the real family is presented (an unattractive picture, entirely lacking the lightness and ease of her earlier family). Immediately Ayckbourn has shown the fantasy family to be more ideal and suitable for Susan which hints that Susan is not at ease in reality , even though there has not yet been much insight into the causes of Susans breakdown. The setting of Woman in Mind is also essential in the presentation of the contrasting families although it is important for the audience to remember that the play is seen from an entirely subjective viewpoint and that although two settings are implied only one is actually the reality. Ayckbourn uses the lighting and sound effects to accenuate the contrast between the two worlds. For example the stage direction at the beginning of the play suggests the setting to be a (small, tidy, surburban garden) but when members of her fantasy family appear the use of lighting ( The garden grows inperceptibly bigger and lighter) accompanies the changes which Susan herself suggests herb garden, lake and tennis courts. The setting is vital as it shows the fantasy family to be more upper class and perhaps this helps Susan to feel more worthy in her life. The use of simpler contrasts such as food and drink also helps Ayckbourn to display the contrast between the two families and he achieves this with the use of props. For example, Susan is offered champagne and gourmet meals by her fantasy family whereas, in reality she is given the less sophisticated sherry and must put up with Muriels dreadful Earl grey omelette. The actions of Susan show how much more she prefers her fantasy family, which is shown by the stage directions, for example (leaving her sherry glass on the card tableshe comes across her glass of champagne and drinks it). The contrast between the two families is also presented through the use of language. An example of this is the way in which the fantasy family use nicknames for each other, for example Big Sis, Susie which helps to show the happy, friendly relationship they have. The tone of voice is completely different however in her reality situations. For example when Gerald defends Muriel in saying that Susan should be more sympathetic towards her because of her present and past sufferings Susan is extremely sarcastic Sorry, sorry, sorry. The fantasy family is also presented as having completely different attitudes towards Susan and Ayckbourn has used this along with the other techniques to emphasise her emotional turmoil. For example her fantasy family are extremely grateful for her and appreciate her Were all going to have to take extra special care of you Were just all so proud of you. The contrast between the two families is important in showing the insecurities Susan has in her life and her fantasy family is a representation of her dreams which for Susan become confused with reality. One of the main reasons for Susans emotional breakdown is her feeling of not being loved which is mainly a result of her distant unloving relationship with Gerald. Gerald and Susan have conflicting opinions even about small unimportant things for example, they have different opinions over the bush in their garden. Gerald calls it a dead bush whereas Susan claims : Its not dead I planted it yesterday. Gerald is also very unsympathetic towards Susans turmoil, for example when Susan says she is not very happy, Geralds unhelpful viewpoint is well who is? These days. Very few. Gerald seems too interested in the book he is writing which is an important factor in Susans breakdown. The lack of a physical side in their relationship leads Susan into the arms of her imaginary lover Andy, whilst in reality she has burnt Geralds history of the parish All sixty pages blazing away. More importantly Gerald seems very unaware of the change in his relationship with Susan. For example when Susan tells Gerald she does not love him anymore, Geralds response is Im not aware my feelings towards you have altered that much which gives a clear insight into the lack of closeness in their relationship to the audience. Susans emotional breakdown is also caused by her relationship with Rick which Ayckbourn presents as one without the usual mother-son communication. Although Susan seems to be quite light-hearted and sarcastic over the fact that their son does not talk to them All of us miming to each other over the table she is however, very aware and upset at the lack of closeness between them. For example, when Gerald explains to her that Rick wants all of his furniture to be sold Susan replies Well have nothing left of him at all. This display of sudden distress to the audience emphasises strongly the emotional stress Susan is experiencing. A different side to Susan is seen when Rick tells her of his marriage to Tess and explains that he does not want the family to meet her, and Susan believes it is because of Gerald Why? Because of your father?. This shows the distance in her relationship with Rick and Susan becomes distraught when she discovers that Rick has always considered her to be an unfit mother I dont want to hurt you anymore, Mum, but God help any daughter who had you as a mother. This is a complete contrast in Susans fantasy life however, because she does infact have a very close relationship with her fantasy daughter Lucy. An example of the difference between her two children is that whereas Rick was very reluctant to tell Susan about his marriage, Lucy is very eager theres something I desperately want to tell you. Ayckbourn has also used the role of an interfering sister-in-law to enhance the worthlessness Susan is feeling. Muriel constantly insists on providing meals and drinks and criticises Susan always where Gerald can hear. An example of this is when Muriel puts Earl Grey tea in an omelette and says to Susan I do wish youd label things, Susan. Its a very inconvenient kitchen to work in , it really is. All of these aspects in Susans reality lead her to having low self-esteem and the questioning of her role. An example of this is when Susan claims that the thrill of being a housewife has gone I used to be a wife. I used to be a mother. And I loved itThe thrill has gone which is a complete contrast to her fantasy world which shows that she clearly wants to be able to employ staff (Murieldressed in very formal maids black bombazine) . The fantasy family are summoned to help her cope and their words are Susans real thoughts which become forced into reality and help Susan to say what she is really feeling. For example, when Bill comes outside to persuade Susan to eat lunch with them Tony and Lucy tell him to drop dead, these are Susans thoughts articulated by the characters and lead Susan herself to say the same Oh, Bill, do drop dead. Susan does have , at that stage still have some control over her life as she is able to banish her fantasy family whenever she wants. The complete contrast in families is extremely important in showing Susans emotional breakdown because the fantasy family has been perfected down to every last detail in Susans mind and shows the ideal life Susan would love to lead. However because of the idealism the fantasy family provides Susan becomes less and less able to control her own creation. This is shown in act two where her fantasy life and reality become mixed and she has entered a world of madness created by herself (What we see are images remembered by her from films she has seen, books she has read, TV she has watched). By this stage in her breakdown Gerald seems to know the fantasy family and talks to them in the light-hearted language that they used with Susan earlier Tony, you old rascal. Whereas it was only in reality that Susan felt ignored which forced her into an imaginary world where she was loved and treasured, now it seems that neither of her families are taking notice of her: LOOK AT ME AT ONCE, DO YOU HEAR? ALL OF YOU!!!. This is the final point in Susans breakdown.

What Others Say about The Yellow Wallpaper -- Yellow Wallpaper essays

What Others Say about The Yellow Wallpaper      Ã‚  Ã‚   "The Yellow Wallpaper" is a short story written by Charlotte Perkins Gilman in 1890 and eventually published in 1892 in the New England Magazine and in William Dean Howells' collection, Great Modern American Stories (Shumaker 94). The story was original not only because of its subject matter, but also because it is written in the form of a loosely connected journal. It follows the narrator's private thoughts which become increasingly more confusing. The structure consists of disjointed sentences as the narrator gradually descends more and more into her madness as her only escape from an oppressive husband and society.    In "The Yellow Wallpaper" the narrator is a young woman who has moved into a strange old mansion with her psychiatrist husband. She is confined to her room as part of her treatment for a nervous breakdown. Isolated and forbidden to express herself creatively, she becomes obsessed with the garish yellow wallpaper. She becomes convinced there are women trapped behind the hideous pattern and eventually becomes lost in her delusions trying to free them (Gilman 1-15).    Charlotte Perkins Gilman originally sent her story to William Dean Howells who showed it to Atlantic Monthly editor Horace Scudder who sent it back to Gilman unpublished, saying, "I could not forgive myself if I made others as miserable as I made myself' (Shumaker 194). When Howells published the story in his own collection he described it as, "terrible and too wholly dire . . . too terribly good to be published" (Shoemaker 194).

Investigating Number of Stomata on a Leaf

Lab Design â€Å"Investigate the effect of a factor on the number of stomata of a leaf. † Research Question: How do differing leaf heights affect the number/density of stomata of a leaf? Hypothesis Stomata are pores, typically found under the leaf (lower epidermis), that control the gas exchange of transpiration, where water vapor leaves the plants, and carbon dioxide enters. I predict that the stomatal density on high leafs is higher than on low leafs. During photosynthesis the chloroplasts in the leaf cells synthesize ATP from ADP as a result of exposure to light, while oxygen is produced as a by-product of the photosynthetic reaction.Carbon dioxide, which enters the plant through diffusion via the stomata, is needed for this process (photosynthesis) to occur. When the chloroplasts in the leafs cell is exposed to higher light intensities, more ATP is synthesized from ADP, while production of the by-product oxygen also increases. This increase in the rate of photosynthesis ca lls for more â€Å"fuel†, i. e. Carbon dioxide. So for a higher concentration of carbon dioxide to diffuse into the plant, the plant must grow a greater stomatal density (higher number of stomata).This will create a larger surface area for carbon dioxide diffusion, the excretion of water vapor (transpiration) and the large amounts of oxygen being produced. As the higher leafs are exposed to higher light intensities I predict the stomatal density to be high. Lower leafs are exposed to lower light intensities due to, for example, shading by top leafs, and will so have a lower stomatal density than high leafs. Variables Controlled: Type of plant- The type of plant that is going to be used will stay the same, i. e. controlled.The type of plant that is used for this experiment is called Quercus Ilex. Amount of leafs (10 ‘high' leafs, 10 ‘low' leafs)- the ensure fair testing the number of leaves tested from each variable will be the same. Apparatus used- Same set up eac h time. Microscope magnification (400x)- Magnification at which the number of stomata will be counted at is at a magnification of 400x. Independent Variable: Leaf Source- The leaf source regarding to the ‘high' and ‘low' leafs is the variable which will be changed to test the difference in number of stomata of the two variables.Distance between high/low leafs- The distance between the height at which ‘low' and at which ‘high' leaves were picked each time had to be of a minimum of 20cm to ensure plausible results. Lower epidermis of leaf used to count stomatal density- Because Quercus Ilex is a dicotyledonous plant, the number of stomata on the lower epidermis will be higher than on the upper epidermis. This is because dicotyledonous plants hold up their leaves horizontally, which directly illuminates the lower epidermis. So, to prevent water loss, fewer stomata will then be located on the upper epidermis. Dependent Variable:Stomatal Density of high leafs Stom atal Density of low leafs Apparatus/Material 10 high leafs 10 low leafs Clear nail polish Slides Pincette Microscope Clear Tape Calculator Method Find a leaf source that has a significant height from which you will be collecting your leafs from throughout the entire experiment. Determine a low area, of little height from the ground, on the source from which you will pick 10 ‘low' leafs. Repeat step 2, except that the area must be at an increased height distance of at least 20cm, to ensure a fair test and collection of ‘high' leafs from a higher area than that of the ‘low' leafs.Choose a leaf of which the stomatal density is to be examined but don't pick it off the plant. This is so that the plants photosynthetic process will not be disturbed which could lead to change in the leafs natural state and affect your results. Paint a layer of clear nail polish on the lower epidermis of the leaf and wait until it has dried. Use your tweezers to gently peel off the dried la yer of nail polish. Gently peel the area of dried nail polish from the leaf completely. You should see a cloudy impression of leaf surface on the piece of tape. This is the leaf impression. Place the leaf impression to a clean slide.Label the slide for identification if necessary. Focus the leaf impression under a microscope magnification of 40x until it is focused and observe the leaf impression. Find an area that is clean of thumbprints, away from the edge of impression, has no damaged areas or big leaf vein impressions in view. When focused, observe the impression under an increased microscope magnification of 100x and make sure it is focused. When focused, observe the impression under an increased microscope magnification of 400x, the magnification at which you will count the number of stomata, and focus.Count the number of stomata you see in the field of view and record the number in a table under the relevant variable (‘high' or ‘low' leaf). To ensure a fair test, repeat steps 9-13 two times by choosing a new spot on the same leaf to focus on. Use the higher number of the 2 repeats to find the average later on. Repeat steps 1-14 ten times for the 10 high leafs and 10 low leafs. Raw Data: How differing leaf heights affect the number/density of stomata of a leaf One manipulation that was done to the raw data to help make it more useful for interpretation was the rounding off of ? Average # of stomata of ?Final?.. etc? , because firstly a stomata cannot be present in the quantity of a decimal and secondly, so that when drawing the graph all numbers have the same number of significant figures which will produce a neater and more accurate graph.

Pleurotus spp

The fungi are a group of eukaryotic organisms. Due to their microscopic cellular dimensions, they are of great interest to microbiologists. Multicellular fungi is familiar to each and every one of us. The velvety blue and green growth on rotting oranges and lemons as well as on stale cheeses, the whitish grey furry outgrowth on bread and Jam, and the mushrooms in the field. These are the bodies of a variety of fungi. Fungi are heterotrophic organisms†They need organic compounds for nutrition.The classification of fungi, unlike that of bacteria, is based primarily on the hracterstics of the sexual spores and fruiting bodies, present during the sexual stages of their life cycle. However, the sexual spores and fruiting bodies are produced only under certain environmental conditions, if they are known to produce them at all. Pleurotus is a genus of gilled mushrooms which includes one of the most widely eaten mushrooms. Species of pleurotus may be called oyesters, abalone or tree mu shrooms and are some of the most commonly cultivated edible mushrooms in the world.They have been very much useful in mycoremediation of pollutants such as petroleum and polycyclic aromatic ydrocarbons. The name pleurotus has been derived from the greek word pleure (side) + otos (ear) which means â€Å"Side Ear†. The following are the details of Pleurotus Genus scientific classification: l. The kingdom of pleurotus is Fungi, II. Phylum is basidiomycota, Ill. class is Agaricomycetes ‘V. Order is agaricales V. Family is pleurotaceae The basic structure of oyster mushroom includes a capwhich may be laterally attached (with no stem).If there is a stem, it is normally eccentric and the gills are extended downward along it. The term pleurotoid is used for mushrooms having this eneral shape. There are certain cylindrical spores which are smooth and elongated. Where hyphae meet, they are Joined by clamp connections. Pleurotus is not considered to be a bracket fungus and most of the species are monomitic (with a soft consistency). Pleurotus Ostreatus Specifications Scientific name: Pleurotus ostreatus Oacq. ) P. Kumm. Derivation of name: Ostre- means â€Å"oyster† and atus means â€Å"resembling. † Synonyms: Agaricus ostreatus Jacq.Common name(s): Oyster mushroom. Phylum: Basidiomycota Order: Agaricales Family: Pleurotaceae Occurrence on wood substrate: Saprobic or parasitic; olitary to more typically in overlapping clusters on living or dead deciduous trees, on rotting logs and stumps, sometimes on conifers; April all the way through November, year-round during mild periods. Dimensions: Caps 5-20 or more cm wide; stipes 0. 5-4 cm long and 0. 5- 3. 5 cm thick. Stripes may be absent. Cap: Moist or dry; smooth; variable in color: whitish to cream, greyish to brown, some with lilac tones; oyster shell- shaped to fan-shaped or semicircular.Gills: Decurrent or glowing from point of attachment; broad; whitish, yellowish in age. Spore print: White t o pale lilac-gray. Stipe: Sometimes absent or rudimentary. If present, lateral to eccentric or even central if fruitbodies are on top of a log or stump; whitish; hairy at base. Veil: Absent. Edibility: Edible, rated as choice. The oyster and abalone mushrooms belong to the genus pleurotus. They have a high saprophyte colonizing ability and can grow on virtually any agricultural waste. They rank among the top six mushrooms produced in the world.It should be noted that the availability of a good strain of mushrooms, suitable substrate for cultivation and control of saprophytic and parasitic microorganisms are the three most important spects for mushroom cultivation. The world production for this genus was 169,000 tons in 1986. The consumption and production of edible mushrooms in developing countries have occurred for many years. There has been a high upsurge of interest in cultivation of this mushroom in the last decade. Because of their spicy flavour and their medical effects in dro pping plasma cholesterol, mushrooms are widely consumed in Europe, the U.S. A and Japan. Many of the fleshy sporocarp species of the many acomycetes and basidiomycetes can safely be eaten while only a few poisonous species of the fleshy fungi can be found . However more than one thousand mushrooms are known, about one hundred mushrooms are edible and only a few are considered of a commercial value. Pleurotus ostreatus is relatively easy to grow. A few trials to produce the mycelium of oyster mushrooms in Egypt using some agro industrial wastes were only recently carried out. The goal of this work was to study the cultivation of oyster mushroom (Pleurotus spp. emphasizing the effect of different media and organic substrates on production. Mushrooms of Pleurotus spp. are commonly known as oyster mushrooms which occupy the second osition among cultivated edible mushrooms worldwide due to their nutritional values. They are widely cultivated all over the world. Its production is remarkab ly affected by the environmental conditions like temperature and relative humidity. In this study, we investigated the production of four species of oyster mushroom: 1 . ) Pleurotus ostreatus 2. ) P. florida 3. ) P. aJor-caJu and 4. ) p. High king Cultivated in every season( January to December) in Bangladesh. The temperature (in C) and relative humidity (%RH) ot culture house in each month, and parameters ot ushroom production were recorded. In all of the selective study of this species, the minimum days required for primordial initiation, and the utmost number of fruiting bodies, biological yield and biological efficiency were found during December to February (14-27 oc, 70-80% RH). The production was found minimum during the cultivated time August to October.We suggested cultivation of selected Pleurotus spp. in winter (temperature zone 14-27 oc with relative humidity for better production and biological efficiency. The environmental factor is very important for the production of oyster mushrooms. Various mushrooms are known to be very sensitive to the climatic conditions. The major environmental factors like temperature, humidity, fresh air and compact materials affect in mushroom production. Pleurotus spp. grows in wide range of temperature (15-30 oc) which also varies from species to species.Oyster mushrooms Pleurotus spp. draw their nutritional requirement from a host substrate or from the agricultural wastes rich in lignin, cellulose and hemicelluloses used for their cultivation. Due to varying nutrients in the substrates, different mushroom yields have been recorded by various workers. Oyster mushrooms are grown from mycelium (threadlike filaments that become interwoven) propagated on a base of steam-sterilized cereal grain (usually rye or millet). This cereal grain/mycelium mixture is called spawn and is used to seed mush-room substrate.Most spawn is made with mycelium from a stored culture, rather than mycelium whose parent was a spore. This is beca use spores are likely to yield a new strain and performance would be unpredictable. Spawn-making is a rather complex task and not feasible for the ordinary mushroom grower. Spawn of various oyster mushroom species may be urchased from com-mercial spawn makers who usually provide instructions for its use. Spawn frequently is shipped from the manufacturer to growers in the same aseptic containers used for spawn production.Inoculum for spawn production is frequently produced in polyethylene bags containing a micro porous breather strip for gas exchange. Most commercial spawn production companies produce spawn only from inoculums that has met strict quality control standards. These standards include verification of inoculums production performance before it is used to produce spawn and assurance of the spawn's biological purity and vigour So ariable in size, shape and colour are the many kinds of oyster mushroom that confident recognition of some species is tricky without resorting to m icroscopic analysis.The process is not helped by the fruiting habit of many Pleurotusspecies that seem to delight in emerging beyond reach, sometimes high up in the crowns of trees. For the most part the various oyster mushrooms are saprophytic on deciduous trees, and only very rarely are they found on conifers. Distribution Pleurotus ostreatus, the Oyster Mushroom, occurs throughout Britain and Ireland as well as in most parts of mainland Europe. It is also widely distributed throughout much of Asia, including Japan, and is present in parts of North America.Several similar species within the Pleurotus genus are often confused, and so distribution data for individual species in this complex group are inevitably subject to some uncertainty. Taxonomic history The Oyster Mushroom was first described scientifically in 1775 by Dutch naturalist Nikolaus Joseph Freinerr von Jacquin 7) and named Agaricus ostreatus. (In the early days of fungus taxonomy most of the gilled mushrooms were inco rporated in the genus Agaricus. ) In 1871 German mycologist Paul Kummer transferred theOyster Mushroom to the genus Pleurotus (a new genus that Kummer himself had defined in 1971), giving it its currently accepted scientific name. Synonyms of Pleurotus ostreatus includeAgaricus ostreatus Jacq. , Crepidopus ostreatusoacq. ) Gray, and Pleurotus columbinus Quel. The blue-grey-capped form of this mushroom is referred to by some authorities as Pleurotus ostreatus var. columbinus (Quel) Quel. Etymology The generic name Pleurotus is Latin for ‘side ear' and refers to the lateral attachment of the stem;ostreatus is a reference to oysters, and in shape the fruitbodies often do esemble oyster shells.The specimens shown on this page show Just how changeable Oyster Mushrooms can be – not only in colour and form but also in their growing habitat. From the top: on a dead Beech trunk; next on a standing live (but surely dying) Cabbage Palm; and at last on a dead branch broken fallen f rom an old Ash tree. Importance of nitrogen sources for the growth of pleurotus spp. :- i) Nitrogen is an essential element for cellular functions, for growth and various metabolic activities, particularly protein and enzyme synthesis. i') The nitrogen content of mycelium ranges between 3-6%. i) Cereal straw used for cultivation of oyster mushroom is a poor source of nitrogen (0. 5 to 0. 8%) and at the time of fructification when most of the nitrogen is utilized for mycelia growth, the depleted nitrogen in the substrate becomes inadequate and limits mushroom yield. ‘v) In the present studies seven dissimilar nitrogen sources : wheat bran, rice bran, soya bean floor, de-oiled soya bean meal, mustard cake, cotton seed cake and cotton seed meal were evaluated for their effect on mushroom yield. v) Cotton seed cake and de-oiled soya bean meal gave significantly higher yield than unsupplemented bags.Review of literature : The oyster mushroom Pleurotus spp is a saprophytic fungus co mmercially cultivated throughout the world because of its tasty basidiocarp and simple cultivation technology. It is also one of the choicest white rot fungi for research scientists to investigate. Pleurotus spp's lignocellulolytic enzymes for bioremediation (Arisoy and Kalan Kayan 1997, Walter et. al. 1997), its flavour compounds, (Mau et. al. 1998), its synthesis of diterpene and polysaccharide (Gutirrez et. al. 1996) and its natural pigment extraction (Shirata and Kato 1998) make it a promising subject for study.Oyster mushrooms are mainly cultivated on residues from agricultural crops such as wheat, paddy, cotton, sugar cane or soybean (Sohi and Upadhyay 1989, Savalgi and Savalgi 1994). Pleurotus spp also have the potential to mineralize and grow on industrial wastes such as tea (Upadhyay et. al. 1996), apple pomace (Upadhyay and Sohi 1988) or non-conventional substrates containing lignin, cellulose or hemicellulose such as dried Populus leaves. (Upadhyay and Verma 2000). These residues are low (0. 5 to 0. 8%) in nitrogen content. Several workers have reported varying fresh oyster mushroom yields using crop residues (Sohi and Upadhyay 1987,Madan et. al. 1987). The variations may be due to the nutrient status of the substrate used for cultivation. The production of oyster mushrooms after the first flush is drastically reduced and there is a tlusn break ot 10 to 20 days depending upon the species of oyster mushroom. The yield turn down could be due to either depletion of nutrients or accumulation of toxic substances unfavourable to fruiting. In Agaricus bisporus, increased yields have been reported by supplementing with various proteins, carbohydrate or oil rich supplements like soybean meal, cotton seed meal, alfalfa meal or corn gluten meal.Sinder and Schisler 1962, Gerrits 1983). In the present studies seven different organic nitrogenous materials were evaluated to find out their effect on yield. The best substrates were further evaluated for their optima l dose with maximum yield. Materials and Methods Prewetted chopped wheat straw (2-3cm) was mixed with calcium sulphate (4% w/w) and carbendazim 50% w. p. (1 5g/quintal) and a rectangular pile prepared. It was given two turnings on alternate days for four days so that the temperature did not exceed more than 600C during fermentation.After four days, the partially fermented traw was pasteurized in a tunnel at 700C for 6h and subsequently conditioned at 450C for 36h. Supplements (wheat bran, rice bran, cotton seed meal, cotton seed cake, soybean meal, de-oiled soybean cake and mustard cake) were separately treated in a answer of carbendazim (100ppm) for 16h. The rate of adding up of all the supplements was 5% (dry wt. ) except wheat and rice bran (10%). Treated supplements were thoroughly mixed at the time of spawning with pasteurized straw. Twenty-day-old spawn of P. ostratuas var florida was added at a 3% wet wt.Five kg spawned substrate was filled into 45x30cm polyethelene bags with 10 holes (5mm ia. ). Each supplement had six replications. Spawned bags were incubated in a dark cropping room (temp. 13-18'C). Colonized bags were opened after 25 days. A relative humidity of 70-75% was maintained by spraying water twice a day; 6-8h light was provided with fluorescent tubes; and carbon dioxide concentration was maintained at 700-780 ppm in the cropping room. Mushrooms were harvested daily before spraying and data were recorded. Biological efficiency (BE) was planned on the basis of fresh mushrooms from 100 kg dry substrate weight.In the second experiment, cotton seed cake and de-oiled soybean cake were further evaluated r their effective optimum dose. The supplements were treated as before, at a rate of 1, 2. 5, 5, 7. 5 and 10% substrate dry weight. Table 1.

Soybean supplementation generally yielded heavier mushrooms in the first flush than cotton seed cake supplementation. Maximum dry matter content was recorded from bags supplemented with 5% de-oiled soybean cake and further increase in supplementation did not yield heavier mushrooms.In cotton seed cake, the heaviest mushroom truit bodies were observed with 0% dose in the first tlusn, while in the econd flush, the lowest rate of application gave the heaviest mushrooms. The dry matter content in the second flush was generally more than the first flush for both the supplements. Interestingly the spore print colour of the mushrooms from 10% soybean was a creamy yellow. The nutritional analysis of mushrooms attain from different supplements is under investigation. The addition of cotton seed cake gave the maximum yield increase (+47. 7%) while soybean cake gave heavier mushroom fruit bodies than cotton seed cak e.The use of supplementation increased the substrate temperature (Figurel and Figure 2) from the fourth day onwards to the ixteenth day. Bags with de-oiled soybean cakes showed a rise in temperature from 3 to 90C over room temperature and 3 to 50C over unsupplemented bag temperature. Cotton seed cake addition showed less temperature rise compared with similar doses of soybean cake. The utmost rise in temperature was between the fourth day and the ninth day.

D. ), Lentinula edodes (1100 A. D. and Auricularia spp (600 A. D. ), it occupies the third place in the world among the cultivated mushrooms. Successful cultivation of oyster mushroom using cereal straw was reported in 1962 by Bano and Srivastava from India. Still, it is not widely cultivated due to inconsistent yields. The fresh mushroom yield or biological efficiency of a species is directly related to strain, substrate nutrition and growth conditions. Sustainable oyster mushroom production can be achieved by employing cultural practices which optimize and integrate nutrient management.Agricultural residues used for oyster mushroom farming provide most of the nutrients and vitamins for growth. Carbon is readily available from cellulose, hemicellulose and lignin from straw, but nitrogen occurs mostly in a bound form and is not available until it is enzymatically rel eased. Various workers have also reported that Pleurotus spp have the capability to fix atmospheric nitrogen (Rangaswamy et. al. 1975, Jandaik and Rangad 1977) but this has not been proved conclusively. In the cultivation of A. isporus the addition of protein rich supplements is a common practice, which indicates that either the compost is deficient in nitrogen or the bacterial proteins present in the compost are inadequate.Rinker (1989) found 37 and 42. 6% more total yield in P. ostreatus from supplementation with barley straw with brewer's grain and 17, 27, 65 and 118% more yield by addition of alfalfa hay at 5, 10, 20 and 40% (dry wt. basis). He also found that supplementation prior to pasteurization increased the total yield, but mushroom size was negatively affected with increased supplementation. In our studies we have not found any significant effect on mushroom size. Influence of supplementation is also species and strain-specific.Somycel 3200 reacted poorly to alfalfa meal and negatively to chicken manure, and Somycel 3001 reacted positively to rice bran and alfalfa meal at the time of filling (Visscher 1989). Upadhyay and Vijay (1989) also observed cotton seed meal as better supplement for P. fossulatus and rice bran for P. ostreatus. Supplementation is absolutely necessary for getting fructification is some strains of P. eryngii (Royse 1999, Upadhyay and Vijay 1991). With supplementation came a rise in substrate temperature, possibly due to faster metabolic activities riggered by extra nitrogen.Royse and Schisler (1986) also observed overheating (from 300C to 470C) in bags where Spawnmate was applied without benomyl treatment, and proposed that it could be due to the growth of competitor moulds. GurJar and Doshi (1995) did not find any effect on yield of P. cornucopiae with 5 and 7. 5% addition of soybean meal in wheat straw and assumed this could be due to a rise in temperature. We identified increases in the temperature of beds from 5 to 90C over room temperature. Therefore, supplements should be cautiously used, because excessive bed temperature (more than 350C) may kill the mycelium.OverstiJns (1995) observed an increase of 19% in mushrooms with the addition of only 0. 5% corn steep liquor and recorded a rise in temperature from 0. 3, 1. 4 and 2. 30C with the addition of only 0. 5, 1 and 2% corn steep liquor. Higher supplement doses gave even higher temperatures, which were harmful and attracted growth of Coprinus sp (Guna segaran and Graham 1987). In A. bisporus, the addition of formaldehyde-pretreated 1 and 2% cotton seed meal and soybean meal at the time of casing produced 20 and 30% higher yields respectively, but higher doses of supplement attracted a lot of contamination (Gupta and Vijay 1992).Supplementation has also been found to facilitate higher mushroom yield in other mushrooms such as Agrocybe aegerita and L. edodes (Zadrazil 1994, Jong 1989). Higher supplementation (3 to 4% w/w) of NPK in rice husk, melon husk and coconut fruit fibers did not give either mycelium growth or basidiocarp from the tubers of P. tuberregium (Isikhuemhen and Okhuoya 1998). Supplementation with de-oiled soybean and cotton seed cake not only gave higher biological efficiency but the fruit bodies were significantly heavier than in unsupplemented bags.

Accidentally Fueling a Diesel With Gasoline

Accidentally Fueling a Diesel With Gasoline To keep people from accidentally  fueling up a diesel engine with gasoline,  most diesel fuel pumps are distinguished by green markings and green fueling nozzle handles. In addition, the inside of a diesel vehicle fuel door has a â€Å"Diesel Fuel Only† label. But what happens if you inadvertently fill your diesel car or pickup with gasoline? Whether you’re new to  diesel ownership or might have both diesel and gasoline powered vehicles in your own personal fleet, it can be oh-so-easy to accidentally misfuel your diesel tank with gasoline. Filling a  fuel tank  is such an ordinary and mundane task, that just a moment’s inattention (did you really need to read that text message?) can cause you to grab the wrong nozzle and pump away. Bad enough if you realize the mistake right away and can get the car towed to a car dealership or independent repair shop to have the tank drained- a $500-$1,000 expensive nuisance. But what if you don’t even realize the mistake and end up driving away with a tank full of gasoline? Chances are you won’t get very far, perhaps just a mile or so. That’s when the diesel in the fuel line gives way to the fresh batch of gasoline on the way from the tank, and the engine starts to run â€Å"funny.† Of course, it all depends on how much diesel remained in the tank before the gasoline was added, and how new and sophisticated the diesel engine is. How Much Gas Does It Take to Harm a Diesel Engine In a 2007 or newer  Ã¢â‚¬Å"clean diesel† engine, any amount of gasoline will probably damage the sensitive emissions control components (DPF,  OxyCat, and  SCR) and system. In older engines with much less sophisticated emissions systems, a lightly diluted (say 90 percent diesel/10 percent gasoline) mix would likely pass through with little or no detriment. It might simply cause reduced engine power, perhaps a bit more noise, and possibly a sharp warning from the emissions sensors that detect something other than pure diesel exhaust. It’s a high concentration of gasoline that spells real trouble. Whether a modern clean common rail diesel (CRD) or an old indirect injection unit, burning straight gasoline or highly diluted diesel fuel will almost certainly result in catastrophic damage to the mighty  diesel engine. Dos and Don’ts If you are fortunate enough to discover you were pumping gasoline rather than diesel before driving away, here are the dos and don’ts. DO NOT  start the engine, even just to move the car from the pumps.DO NOT  turn the ignition on, even just to unlock the steering wheel. This could activate an electric fuel pump and feed tainted fuel into the engine injectors.  DO  tell the station attendant you cannot move the car and pay for the fuel dispensed.DO  call your roadside service provider and request a tow to either the vehicle’s brand dealership or an independent repair shop.DO  have the fuel tank drained and receive confirmation that the contaminated fuel was limited to the fuel tank. If you don’t notice the  mis-fueling error until the car has been driven, stop as soon as it is safe and call your roadside service provider to request a tow. Unfortunately, the price to repair the damage will be very expensive and this is a situation that  will not  be covered by your automaker’s warranty. What Gas Does to a Diesel The problem is multifaceted. It is a function of the completely different burn characteristics of the fuels (volatile and explosive gasoline versus high flash point diesel fuel), and the peculiarities of engine design in regards to how fuel is ignited (spark ignition  versus  compression ignition). Gasoline is formulated to resist auto-ignition in a spark engine (depending on the octane), so this fuel introduced into a diesel engine either won’t ignite or will more likely ignite at the wrong time causing severe  detonation- literally a shock wave throughout your cylinder. Though diesel engine  reciprocating components- pistons, wrist pins, and connecting rods- are built to withstand enormous explosive force, the shock wave effects of uncontrolled detonation can easily destroy them. If by chance major engine damage is avoided, there are other serious consequences. Diesel fuel itself acts as a lubricant  for the fuel pump and delivery system as well as the  valve train. Running thin, low viscosity gasoline through a diesel fuel system would starve it for lubrication and cause those sensitive components to rub together, eventually destroying them. Additionally, the entire fuel system will have been affected. That means the fuel pump, fuel filter, and  fuel injectors will likely need replacement. In the worst-case scenario, it might be cheaper to just replace the engine and components. Good News for Newer Diesel Vehicles Gasoline vehicle fuel filler openings were made smaller in diameter beginning in the early 1980s. This was in response to the mandatory use of unleaded fuel to protect  catalytic converters  and the negative effects of lead to human health. That’s why the smaller diameter gas filler nozzle fits into the larger filler opening of diesel cars. Then in 2009, BMW launched its clean  diesels  in the U.S. with a â€Å"mis-fueling protection device,† essentially a gas cap replacement with a diameter specific to diesel nozzles, as standard equipment. Audi followed in 2011 with a similar device, and beginning with 2013 vehicles, Volkswagen redesigned its fuel fillers to accept only diesel fuel. Today, nearly every diesel vehicle- car or pickup- will only accept diesel fuel. What Diesel Fuel Does to a Gasoline Engine Fortunately, this one is almost impossible (notice we said almost) to ignore, since the larger diesel filler nuzzle won’t fit in a narrow gasoline filler neck. But if you do manage to get diesel fuel in your gasoline tank, the engine will probably not even start, and if it does, it’ll run terribly and probably smoke like a chimney. Engine damage will most likely be minimal to none, but a thorough and expensive fuel system flush will certainly be in order. This article was edited and updated by Larry E. Hall

Psychological Testing and Assessment Paper Essay

Psychological Testing and Assessment Paper - Essay Example Psychological test is one of the recognized measurement tools used in psychology. Cohen, Swerdlik and Sturnam (2013) define psychological test as devices and/or procedures used to measure psychological variables with regard to their effects on human life. Cohen, Swerdlik and Sturnam (2013) alternatively define psychological test process of determining psychology related variables through use of procedures and devices designed to produce a sample of behaviors. Counselors, and marriage as well as family therapists rely on psychological tests to accomplish their treatment goals of dysfunctional elements in their clients. Counselors need psychological tests such as interviews and observations to study behaviors and conducts of their clients. Interviews enable counselor to perform personality, intelligence, attitude, brain and behavioral tests on clients. Marriage and family therapists perform personality tests on related individuals facing difficult time to understand inherent motivators to act as they do. Personality tests enable counselors to weigh trust, confidence, courage, self-esteem, understanding, honesty and transparency between and among clients (Nichols, 2013). Measuring trust is usually important in marriage therapy where couples experience problem due to distrust. A married woman may use observations of behavioral change in the partner to suspect infidelity. If the two have not found time to talk about their challenges, the woma n would continue to express distrust in the marriage and behave in a manner that only escalates instability in the marriage. Marriage and family therapists also measure honesty levels in their clients to determine commitment of related members in their relationships. Honesty here, concerns open and truthful communication among members. Therapists understand dishonest communication have great propensity to lead to unstable relationship within families.
