“the Social Responsibility of Business Is to Increase Profit”

Businesses have many responsibilities, the primary role being, to make profit and then in turn grow and expand as a business in the hope that they increase profits. After all, not many people want to be in the business of losing money, it is simply the function of a business †¦ to make money. However, in saying that, I would disagree in saying that this is entirely a â€Å"social† responsibility. Businesses have a responsibility to their stakeholders and/or their shareholders to increase profits, but socially they are required to do so much more. In terms of â€Å"social† responsibility, in this current day and age, businesses have a responsibility to society. I believe consumers are generally not concerned about the profit businesses makes, they are more concerned about the quality, service and value they receive from dealing with a business, and more importantly whether the success of the business was gained by them following socially and ethically responsible business practices. In the past, businesses would forfeit their social responsibility at the cost of increasing profit. A good example of this is multinational conglomerate, Proctor & Gamble, identified by PETA as a corporation that actively participates in animal testing1 to ensure that their products are safe for people to use. Yes, they are fulfilling their â€Å"social† responsibility in ensuring that their products do not harm their consumers, but now society and organisations are pointing the finger and actively boycotting companies such as Proctor & Gamble, for ignoring their social responsibility. Businesses have had to turn things around to adapt to the views of changing society. Being socially responsible is now a costly exercise. Due to their previous poor business ethics, they have to date invested almost $250 million in alternative testing methods in an effort to abolish all forms of animal testing. 2 Not only now is it socially unacceptable to practice â€Å"bad† business ethics, but it is socially unacceptable for businesses that make too much money to ignore the needs of the needy. Bill Gates, founder of Microsoft together with the efforts of his wife Melinda have established the Bill & Melinda Gates Foundation. The foundation donates millions of dollars every year, aiding many projects with their slogan being â€Å"all lives have equal value†. It is now the duty of businesses and many large corporations to be socially responsible and contribute to society on a larger scale. It is simply incorrect to say that increasing profit is the sole responsibility of a business. It is the social responsibility of a business to be socially responsible, in all facets. Portraying a ‘socially responsible’ image is detrimental to increasing profits, this has not always been the case, many companies that were once selfless entities who’s only mission was to profiteer at any cost have realised that with the changes in society, they have had to change the way they conduct their business. Sadly, many businesses and corporations participate in â€Å"socially responsible† activities for the purpose of increasing profit, businesses are not changing their packaging to pink to ‘secretly’ support breast cancer, they do so, so that you and I know about it. These so called acts of social responsibility are a form of advertising and they are done to show consumers just how â€Å"good† they can be. It is not the social responsibility of businesses to increase profit, but it is the social responsibility of companies to be socially responsible to increase profit.

Hills like White Elephants Essay

In â€Å"Hills like White Elephants,† Jig describes the hills from a distance like white elephants. That description signifies that, for Jig, her pregnancy is something that is precious while a burden at the same time. In order to understand the situation of Jig, it is important to note that white elephants are considered to be sacred and symbolize justice in Southeast Asian monarchies. On the other hand, these elephants come with a costly price in terms of its upkeep or maintaining its health. White elephants are oftentimes given as precious gifts for royal members of the family since they are the ones who are capable of taking care of the costly needs of the elephant. But for the average individual, being given a white elephant means having to take care of a burden that is supposed to be treated as a precious gift. Apparently, the hills in the story symbolize the pregnancy of Jig and the description of the hills as white elephants suggest that her pregnancy is both a precious gift and a burden. On the part of Jig’s American male companion, the fact that he wants Jig to have an abortion suggests that he sees her pregnancy as a burden. Moreover, the railroad tracks in the story’s setting suggest a dividing line between two distinct landscapes—a barren and dry land on one side and a green landscape on the other. Jig’s attention is focused on the landscape while the American is having a conversation with her, suggesting that she is concerned between choosing which side to take—a happy life with her child or a barren life with her American companion but without her baby—while the American is busy convincing her to let go of the baby. In â€Å"A Rose for Emily,† the setting used by the author, William Faulkner, is the fictitious post-war town of Jefferson. In the town, women are not allowed to walk the streets without wearing an apron, thereby suggesting that there is a form of discrimination against women. However, Emily Grierson can opt not to follow the rule because she came from an influential family. In fact, there was even a time when she was given the privilege of not having to pay taxes. Thus, the society’s perception towards Emily by that time was that she was a woman of distinct position. She was someone who is not like the average woman in town as she is capable of doing things that the average women in town cannot afford to do. Moreover, the setting of the house of Emily in the story reveals something about her character. The house is considered to be once a majestic edifice in the town only that it has turned into â€Å"an eyesore among eyesores (287)† later in the story. The reason behind this is that the house was no longer well taken good care of even though Emily has employed a man—both the her gardener and her cook—to look after the house. The time when the townsfolk have noticed the searing stench emanating from Emily’s house all the more gave the house an ugly reputation. At the end of the story, it is revealed that the stench came from the decaying body of Homer, Emily’s lover, who was laid in one of the house’s beds as it rotted for years. Apparently, it is also revealed that Emily had been sleeping with the corpse of Homer all the time when the stench lingered around the house. It symbolizes the decay of the personality of Emily, perhaps dying with the death of Homer. The setting of the house clearly represents the decaying personality of Emily and the predicaments which caused her grief and despair. Victoria Battistelli, (A Rose for Emily) I agree that Emily is an old woman and that she should not have died in that decrepit house. However, I think it was Emily’s decision to stay inside that house until her dying days for one reason—her lover, Homer, is there in one of the bedrooms. Interestingly, it was Homer’s stench—for his dead body was decaying all the time that it was there—that roused the interest of the rest of the people in town although they were not aware it was Homer’s. More importantly, there are evidences in the story which suggest that Emily slept with the corpse of Homer: the lock of hair beside Homer’s body and the shape of the pillow that appear to suggest that somebody’s head was on top of it. These things, among others, indicate that Emily chose to stay inside the house and even sleep with Homer’s corpse. Sadly, though, she did not have to put herself in that position. Apparently, her strong emotions for Homer caused her to withstand the putrid scent of his corpse and stay inside the house. Do you know of other indicators that Emily was willing to stay inside the house even though it was reeking of bad smell? Debbie Wong, (Hills like White Elephants) I definitely agree that Jig was thinking of her pregnancy as she was concerned as to whether she should follow the suggestion of her American companion or to follow her desire to keep the baby for herself. It seems that Jig was weighing the odds for each side of the coin, so to speak, although she gave-in eventually to the demands of her American companion. Her pregnancy is truly a white elephant—a burden and a gift, a burden for her American companion and a gift for Jig. Are there any indicators in the story that says something about Jig’s pregnancy as a burden for herself, or that she was tempted to give-up her baby before finally deciding to do so?

Certainty vs. Doubt

I believe the dispute between the two virtues, certainty and doubt, is very controversial. Despite the clear sides that people have fixed themselves to, there are pros and cons to both. A person’s doubt can cloud their judgment. Yet it can also aid them in making the better decision, by questioning and eliminating the inferior options. On the other hand, a person’s certainty can blind them from seeing the truth. Regardless of these cons, both are necessary in the everyday choices of life. Isaiah Stock, an APLAC student at University of North Carolina, said, â€Å"Think of certainty and doubt as parts of an automobile. Certainty is considered to be the accelerator, while doubt is the steering wheel. You can get nowhere without driving certainty—but without steering through the impediments in your way, you will surely crash and burn. † I consider this to be a very acceptable metaphor of the balanced relationship between certainty and doubt. An excess of either, on the other hand, is detrimental to one’s wellbeing. I t is necessary to balance certainty and doubt in order to accomplish all of one’s life goals. But I believe that, because doubt is so highly misconstrued, doubt is more necessary in the process of making decisions. Doubt is often viewed as a negative idea in our modern society, but in reality is very beneficially, when used correctly. It is not completely contradictive of certainty, but more somewhere in between the two. The World English Dictionary’s definition of doubt is â€Å"a lack of belief or conviction about something. † We should accept the fact that doubt is a part of us, as a human race, because it is part of our nature. We are curious from birth, and to question anything and everything that we want to know more about is perfectly acceptable. I feel that it’s more in the levels of doubt that we use, that we should start to feel worried. Take building a house of cards, for example. Every card we add brings the risk of sending the whole tower tumbling over, but that is a risk we have to take, in order to achieve our goal. â€Å"I will doubt everything that can possibly be doubted, and if anything is left, then it will be absolutely certain†¦ Then I will consider what it is about this certainty that places it beyond doubt. (Descartes). Descartes, in my opinion, is yet another, if not extreme, example of the beneficial effects of doubt. He believed that man should not believe in anything that the smallest reason to doubt. In other words, anything that we believed to be true was untrue, until proven undeniable. His theory, dubbed the Doubt Theory, stated that everything we believe is true comes from our senses, which Descartes believed to be both unreliable and untrustworthy. So he claimed we should doubt everything because of this. In this way, I believe that there will be more qualified and non- defective results. In conclusion, doubt should be viewed as a virtuous idea. Of course, we must use it with caution and wisdom, so as not to abuse one of the many things we have been blessed with, as human beings. As is the case with most matters, we must be careful to balance out our doubt and certainty. Doing this will aid in the betterment of our human nature, and once we learn how to balance the two together, we will be closer to the quintessential being of which we wish to be.

Today's Downsizing Teachers in the America Case Study

Today's Downsizing Teachers in the America - Case Study Example The search results also showed some personal opinions of common people and some officials, some of whom supported the downsizing while some reported that firing of teachers was not appropriate. As far as academic literature is concerned, I searched the Google books but could not find actual information in satisfactory quantity regarding teacher downsizing in America. Authors have written books on general downsizing in America with a little bit consideration to teacher downsizing. However, I was able to find some good research papers in which the researchers considered the causes and problems caused by teacher downsizing and discussed the solutions. But again, there were very few researchers who pointed out this specific topic and most of them discussed downsizing in general. In short, I was able to find easily on the internet some good news reports, websites and photos regarding teacher downsizing in America. 2) First source that I studied was a website that contained an article by A ndrea Peters. In her article, she talked about the layoff notices that were being sent to thousands of teachers in America.

Power of query optimization Asystematic Approach to cost-Based Dissertation

Power of query optimization Asystematic Approach to cost-Based optimization in Data Mining enviroment - Dissertation Example Up till now, there has been extensive research done in order to give database support to the mining operations. Nevertheless, the emphasis in such endeavors has been, most typically, laid upon the mining of a single data set although, most of the times, the user has to look up for multiple data sets that are acquired from various data sources. Thus, for such cases, it is extremely essential for the KDD process to compare the patterns from various data sets and comprehend their relationship with each other. For this purpose, the multiple data sets in a KDDMS require support for the complex queries. Due to this reason, new functionality and optimizations are needed that particularly emphasize over the frequent item set mining. Faster response to queries is the prime function of the query optimization. The data is better known to the semantic optimizer rather than the user. Thus, the semantic optimizer is able to replace the query of the user with another query that provides the same ou tcome more efficiently in lesser time. The efficiency of the new query is due to the execution of less work for the retrieval of the selected result tuples from the data base. The most advanced query optimizers select the one â€Å"best† plan during the time of the compilation to execute a given query (Ramakrishnan and Gehrke, 2000). The cost of execution for the alternative plans is calculated, out which the one is selected that has the overall cheapest cost. Conventionally, the cost is determined on the basis of the average statistics of the overall data since the prime purpose is to identify a single plan for all data. Nevertheless, the significant statistical variations of various data sub-sets may yield poor performance of the query execution (Christodoulakis, 1984). The basic disadvantage is the highly coarse optimization granularity in which just one execution plan is selected for the entire data. Important opportunities for effective query optimization are left out be cause of this sort of â€Å"monolithic† approach (Ramakrishnan and Gehrke, 2000). Thus, the research problem is to augment the cost-based optimization in data mining for patterns, in single and multiple databases. Therefore, the present study will focus on the cost-based optimization of the queries in data mining. 2. Topics covered There are numerous research papers that have been published in the area of Data mining, Data ware-housing and Query Optimization Techniques however the researches in the past do not clearly specify the conditions under which, what kind of query optimizer will probably possess more weight or points than the others. According Yu and Sub (n.d.), rules are deduced from the restriction clauses of the queries that are received at the database and also, from the outcome that they generate. It can also be stated that the cost of each query is different for the approaches through which the two syntactically distinct queries generate the same outcome. Ullman (1998), in his research, explained the principle of semantic query optimization that refers to the use of semantic rules, for instance, to re-generate a query into an equivalent but less expensive query, in order to minimize the cost of query evaluation. Subramanian and Venkataraman (n.d) in their work suggested the architecture to process the queries of complex decision support that incorporates various heterogeneous data sources and puts forward the concept of transient-views and moreover, formulates a cost-based algorithm that requires a query plan as an input and develops an optimized â€Å"covering plan† through reducing the redundancies in the original-input-query plan. According to the research work of Stefan Berchtold et.al (2001), the problem of extracting all objects

Environmental Kuznets Curve Essay Example | Topics and Well Written Essays - 1250 words

Environmental Kuznets Curve - Essay Example On the other end of the continuum, economists advocate that progress in technology along with sustainability of natural resources would lead to little reliance on natural environmental resources; thus, economic growth ought to be there (Beckerman, 1992). As noted by (Shafik, 1994), empirical evidence was lacking to support either of the above two arguments. Furthermore, much difficulty was faced in operationally defining the dimensions of environmental quality. Although no single parameter can be used to define environmental quality, a combination of parameters has been developed for environmental deprivation in order to demonstrate the effect of economic growth on the quality of environment. Amongst one of the first studies conducted in this regard were those of the World Development Report. As shown in Appendix 1, some dimensions of environmental deprivation (including emissions of carbon dioxide and solid waste pollution) are highly correlated with income, meaning that they increa se as income increases; in other words, in terms of these dimensions, economic growth has a negative effect on environment. Others (including lack of safe drinking water and sanitation facilities) tend to decrease as income increases, implying that economic growth can be used as an instrument for enhancing quality of environment. ... Firstly, growth is demonstrated to have what is called a â€Å"scale impact† on environment; that is, the larger the size of economic activity the larger the rate of environmental degradation (Grossman, 1995). This is due to the fact that an increase in income is the product of increasing factor inputs and natural resources of which waste and environmental degradation is a by-product (Grossman, 1995). Secondly, the positive effect on environment of economic growth is what is known as the â€Å"composition effect†; that is, as income increases, structural economic changes tend to increase the proportion of environmentally friendly practices in the economy (Grossman, 1995). Thus, as per the combination of these two effects, environmental quality tends to go down due to structural economic changes in the economy that is in transition from rural to urban and from agricultural to a largely industrial structure but starts to improve as the economy undergoes a second structura l change from heavy industrial processes to technology-intensive ones (Panayotou, 1993). Finally, the technological advancement that accompanies economic growth and the resulting increased expenditure on research and development leads to the adoption of cleaner, environmentally friendly technology which enhances the environmental quality. This is termed as the â€Å"technique effect† (Grossman, 1995). As the Environmental Kuznets Curve suggests, the inverted U relationship between quality of environment and economic growth implies that the harmful impact on environment ( as per the scale effect) is explicit during the early phases of growth but is ultimately offset by the positive effects of the other two effects ( composition and technique) in the later stages. It is here that the

Why did men like Joseph Plumb Martin join the army Essay

Why did men like Joseph Plumb Martin join the army - Essay Example Most of the recruits were young and army provided them with an opportunity to escape home and experience adventure of fighting against their enemy. But unfortunately, the reality was far from the rosy picture as envisaged by the new recruits. The common soldiers were faced with huge hardships where food had become scarce and proper clothing a distant dream. The long drawn battle of American army had severely affected the welfare of the soldiers. The new recruits were just sent to the front to fight with enemies without training. They were also not only deprived of adequate food and shelter during tough weather conditions but were also not paid their wages on time. Martin asserts that ‘I well know, for I have fought by their side’ (183). The delivery of supplies for food and other goods use to become difficult due to weather conditions which resulted in starvation and death. Most of the recruits went to fight without training because they felt that it was their moral duty to fight for their country. Hence, need for training was not important for the common soldier. The young recruits later became accustomed to the grim conditions of the war but were unable to do anything except accept the situation.

Explore the ways in which Shakespeare presents Lady Macbeth and Browning presents the speakers in Porphyria’s Lover, My Last Duchess and the Laboratory Essay Example for Free

Explore the ways in which Shakespeare presents Lady Macbeth and Browning presents the speakers in Porphyria’s Lover, My Last Duchess and the Laboratory Essay Shakespeare presents Lady Macbeth in such a way that she is shown as a strong and powerful woman. Her ability to manipulate Macbeth to murder Duncan in order to get more power is a key example of this aspect of her character. Browning also presents his speakers in a similar way to Shakespeare through their need to control. The main way that both authors achieve this is through the use of language. Techniques such as rhyming couplets and semantic fields are used to emphasise the control that the characters have or want to achieve. Additionally, a range of imagery is used throughout all of the texts, allowing the reader to gain an understanding of the characters. In their writing Shakespeare and Browning don’t follow the general patriarchal society which makes the murders so horrific and odd as women weren’t generally thought of as thinking of murder or committing a murder. Lady Macbeth tries to gain power by pushing Macbeth to murder Duncan, when she says she would have ‘dash’d the brains out, had [she] so sworn as [Macbeth]/ [Has] done to this’. This shows Lady Macbeth using horrific imagery to manipulate Macbeth into murdering Duncan as she is saying if she would ‘das[h]’ the brains out of her own child, he should be able to murder Duncan. Lady Macbeth wants to be more masculine so she feels more superior to Macbeth. Lady Macbeth uses violent imagery, which proposes that she isn’t the stereotypical woman that society suggests. The phrase ‘das[h] the brains out of her own child’ shows she is prepared to do anything to gain power. In the 17th century women were seen as nurturing and caring so to be thinking about murdering her own child would be seen as horrific. In a similar way Browning’s poem ‘The Laboratory’ also uses a variety of imagery; however here he particularly focuses on the imagery of death. The use of an exclamation mark at the end of ‘And Pauline should have just thirty minutes to live!’ shows the speaker is excited at the prospect of murdering her partner’s mistress as it is as though she is speaking in a loud or excited tone. The use of imagery ‘just thirty minutes’ shows that she likes the  pressure and the short time scale for murder. By doing this it emphasises the woman’s psychotic behaviour as women were generally not meant to even be thinking about murder never mind excited for it. In all three of Browning’s poems the speakers use self-justification for their actions. In ‘Porphyria’s Lover’ the speaker justifies murdering his lover. When the speakers says ‘From pride, and vainer ties dissever,/ And give herself to me forever,’ he justifies murdering his lover; he believes that, because she is a higher class than him, she cannot truly love him and is too proud to be with him. As there was no proof that the woman was going to love him he is using his deluded personality as an excuse for murdering her. In a similar way in ‘The Laboratory’ the killer also uses self-justification. The speaker describes ‘The soul from those masculine eyes’. This shows the speaker criticizing the enemy to make it look more acceptable that she is murdering someone. In society a woman is not generally thought of as a murderer, so by her describing the victim as a ‘masculine’ person she is trying to make her a ctions reasonable. Shakespeare and Browning both use semantic field of love and death with Browning particularly focusing on possession in ‘Porphyria’s Lover’. When the speaker says ‘she was mine, mine’ he implies he loves her so much that he wants to kill her so that no one else can have her. This is showing the speaker’s narcissist personality because he would rather her be dead so she can’t be with anyone else. This is similar to Shakespeare’s work as Lady Macbeth and Macbeth see the power as their possession. An example of semantic field of death in Macbeth is when Lady Macbeth says ‘who should against the murderer shit the door’. This contrasts with the semantic field of love in Macbeth. Through this juxtaposition, Shakespeare shows that lady Macbeth is willing to use her love as a means to manipulate Macbeth; she will use her love to control him, no matter what the cost. In both Macbeth and Browning’s ‘The Laboratory’, the speakers use masks, both literal and metaphorical, to cover up their psychotic behaviour. An example of this is in ‘The Laboratory’ where the speaker says ‘Now that I, tying thy glass mask tightly.’ Here, her mind is becoming fragmented and she is  literally hiding herself from others as she protects herself from the fumes. In Macbeth Lady Macbeth urges Macbeth to put the mask of a murderer back on- ‘Was the hope drunk/Wherein you’d dress yourself?’ –which suggests Macbeth is feeling guilty. If he adopts a faà §ade he’ll be able to kill without feeling remorse and no one will suspect them. This also implies that they are hiding their true personality and putting on a mask to hide what they are really going to do. People today still put on an act to hide their true feelings; Shakespeare and Browning’s texts allow the modern audience to relate t o this universal concept. Browning and Shakespeare both present their speakers as mentally disturbed but use rhyming couplets as a way to create stability to cover up their true personality. In ‘The Laboratory’ the speaker and her motivations are seen as troubling and sinister so using rhyming couplets, which creates a predictable pattern acts as an attempt to mask their true personality; the pattern attempts to impose a structure in her life. Browning also uses rhyming couplets in ‘My Last Duchess’ to also create stability to mask the speakers deranged personality; the couplets are limited, as is the Duchess’s life, so it suggests that the Duke has a level of structural control although he was unable to control her behaviour. In a similar way Shakespeare also uses rhyming couplets but uses them to show lady Macbeth’s firmness of decision: ‘Away, the mock the time with fairest show:/False face must hide what the false heart, doth know.’ Here Macbeth has giv en into Lady Macbeth’s persuasion and had made his final decision on murdering Duncan. Using rhyming couplets seems misplaced as they are orderly yet a murder isn’t. Shakespeare was influenced by The Gunpowder Plot as the link between Guy Fawkes’s plan to kill the king and Lady Macbeth’s idea to kill King Duncan was very similar in a way that it was unnatural to kill the king and go against what God has chosen. Shakespeare shows Lady Macbeth thinking and talking about murder; Browning also uses a woman as a murderer in ‘The Laboratory’. Both authors use women to show how horrific the murder really is, as women were seen as caring, mother figures who were automatically seen as kind and loving- so for women to be thinking of murder shows their psychotic personality and rebellion  against social expectations. An example of this is when Lady Macbeth says ‘unsex me here,’ which shows Lady Macbeth wanting to become more masculine, so she will be more capable of murder. By Shakespeare presenting Lady Macbeth in this way shows us that Lady Macbeth is capable of anything which is seen as unusual because women weren’t generally seen as being able to do a lot of things men were. Another example of this concept is in ‘The Laboratory’ when the speaker says ‘Sure to taste sweetly. This shows that the speaker finds pleasure in murdering someone. The speakers in ‘My Last Duchess’ and Lady Macbeth are both controlling and possessive. In ‘My Last Duchess’ the speaker says the metaphor ‘Taming a sea-horse.’ which suggests that the Duke has a controlling personality as it is like he is treating the Duchess as a slave and modelling her into what he wants her to be. The Duke shows he is controlling possessive as he says ‘That’s my last Duchess painted on the wall’; by using the possessive ‘my’ the Duke show us his true personality as he is saying the Duchess was, and still is, his. An example of possessiveness from Macbeth is ‘Only look up clear;†¦leave the rest to me.’ This shows Lady Macbeth being assertive and taking charge showing us her controlling and manipulative personality. By doing this it shows us that Lady Macbeth is the one who was the most power hungry as she is taking control and sorting everything out; it also shows that Macbet h is quite timid when it comes to Lady Macbeth because he just follows her orders. As women were seen as weaker than men, Lady Macbeth has to use Macbeth to get what she wants. In conclusion both Browning and Shakespeare present the characters as powerful and manipulative. Browning uses pronouns in both ‘The Laboratory’ and ‘My Last Duchess’ in order to show the relationships between the characters. Shakespeare also uses role reversal as he uses a woman telling a man what to do instead of the other way around; this could therefore be seen as subverting traditional gender roles. In this century a woman telling a man what to do is not seen as unusual but in the 17th century it wasn’t seen as the standard thing.

Eco-friendly and formaldehyde-free Essay Example for Free

Eco-friendly and formaldehyde-free Essay Dont have the budget for solid-wood kitchen cabinets, but still want to avoid VOC emissions? Youre in luck. In recognition of the new school year, heres a pop quiz: What do mussels those delectable morsels from the sea best served in a white wine sauce and plywood have in common? Cant see the connection? Read on! Unless you, like some mussels, have been living under a rock, you will be aware of the growing hullabaloo about VOCs (volatile organic compounds) and how we dont want to be breathing them in. The bad news is, if youve had non-solid wood kitchen cabinets installed recently or purchased furniture made of composite wood products, you may be doing just that. But theres also good news. Governments and manufacturers have heard the ruckus about VOCs and taken action and, just when you thought you had all the possible options for kitchen cabinet materials nailed, out they come with new ones to confuse everyone. Hence this primer to bring you up to speed and make sense of it all. It used to be that consumers had two extremes to choose from when they shopped for kitchen cabinets. The lower-cost options were cabinet components made of either particleboard, medium-density fibreboard (MDF) or plywood. These are all composite wood-panel products traditionally containing glues that, when they come to room temperature, emit VOCs in the form of potentially carcinogenic urea formaldehyde (UF). At the other end of the price extreme was solid wood, which doesnt have this problem but costs more. Many contractors still tell clients that their choices are either/or, and urge them to go for the higher-priced wood for various reasons. Luckily for consumers who dont have the budget for a solid-wood kitchen but who want to avoid VOC emissions, this all changed about three years ago, says David Beattie of Rayette Forest Products, based in Concord, Ont. That was when Oregon-based Columbia Forest Products introduced PureBond, which Mr. Beattie describes as a veneer core hardwood plywood made with glue containing zero UF. This plywood, whose layers are joined by a soy flour-based glue, is one of a growing number of alternatives to products in which UF-emitting glues are used. It was introduced by Columbia ahead of new industry standards in the United States the toughest there to date set by the California Air Resources Board (CARB). The story behind PureBond and this is where the mussels come in is rather romantic, although romance isnt something youd normally associate with plywo od either. It seems that an Oregon State University researcher was vacationing along the Pacific Ocean. While sitting on the beach watching the waves pound the shoreline, he noticed clumps of mussels clinging to the rocks. No amount of battering surf could dislodge them. What are they secreting, he wondered, that allows them to adhere to the rocks so solidly? In short, research into those secretions led to the soybean-based, zero-UF glue used in PureBond plywood. Columbia Forest Products says using PureBond is cost-neutral when compared with its former UF-emitting panel products. Thats despite the large expenditures the company says it has made to develop the product. This is an important development, romantic beginnings aside, because, according to CARB findings, The most significant source of (UF) emissions we face on a daily basis comes from the composite woods in our furnishings and cabinetry. At this stage, the glues that work in zero-UF plywood arent being used for particleboard or MDF. Some sources say these adhesives simply dont work with those materials, which have different natures than plywood. But there is something called no added UF particleboard, as well as a kind of MDF whose emissions are in the acceptable range. Look for a particleboard called SkyBlend developed by Oregon-based Roseburg Forest Products and made with recycled and sustainable raw materials, and Arreis MDF, made by SierraPine, which is based in California. Both SkyBlend and Arreis are considered green building products that meet North American VOC-emissions standards. They, and PureBond, are readily available in Canada. With this kind of progress in the wood-products industry, Rayettes Mr. Beattie predicts it wont be long before all composite wood materials are formaldehyde free. If youre in the market for new kitchen cabinetry and your budget wont cover solid wood models, discuss your material options with your contractor. Its important to ensure that hes up to speed on the latest technology and knows what your preferences are. Most general contractors have preferred cabinet suppliers. Find out if those suppliers offer a zero or low UF-emitting panel product. If your contractor still thinks there are only the two extremes to choose from, tell him about the mussels. I know that not everyone is up in arms about UF emissions. Even if you arent, however, I still urge you to find out where your contractors cabinet supplier buys his composite wood products. If theyre coming from certain Third World countries, you could be getting third-rate quality along with those high UF levels. Some contractors will go the foreign route because its cheaper even though those materials often dont meet our more stringent Canadian and North American standards. Canadian materials can cost more than those made in Third World countries. For example, in an average-sized kitchen, using Canadian-produced panel materials is about $500 more expensive than if you went with the Third World products. Still, its not that big of a premium when you consider the benefits of buying Canadian: zero to low UF emissions, and the fact that youre supporting our economy, our workers and our renewable forestry practices. Im not even going to get into the whole human rights thing. As a friend of mine says, when it comes to buying Canadian and going as green as we can, Its all good.

Structural Engineering Centrifugal Pump Test Laboratory Engineering Essay

Structural Engineering Centrifugal Pump Test Laboratory Engineering Essay This report examines the centrifugal pump. Firstly by examining the system head characteristic, then by examining the effects varying the motor speed has on a single pump. Finally the report examines and compares the use of two pumps in series and then in parallel. Theoretically examination of the system head characteristic should yield a graph of system head against volume flowrate which is curved, the curve should begin above zero from the y axis, due to static lift. Theoretically examination of the effect of varying motor speed across a system of a single pump should show that higher motor speeds lead to higher efficiency in the pump system along with larger changes of power across the system, and a larger drop in head values. Finally comparison of a system with two pumps used in series and in parallel should show that the method used will not have an effect on the efficiency of the system. However it should also show that the system in series has twice the head values of that in parallel and that the system in parallel has twice the volume flowrate values of the system in series. Overall they should have the same Mass flow. Upon comparison of the results obtained with theory, it is evident that for the most part, the experimental results agree with theory. Any minor disagreements between theory and experimentation will be explained in the discussions and conclusions section of this report. This report serves to display knowledge and understanding of the operation of a centrifugal pump gained from completion of the experiment. Introduction The purpose of this laboratory is to study the operation and performance of a centrifugal pump. Centrifugal pumps are an example of a fluid machine. Fluid machines are devices that transfer energy to or from a fluid. Fluid machines include pumps, fans and compressors. This experiment deals with a pump. Pumps are devices used to move gases or liquids from lower to higher pressure. The difference in pressure is overcome by adding energy to the system. Specifically, centrifugal pumps operate by converting rotational kinetic energy into hydro dynamic energy. The rotational energy is typically supplied by an engine or electric motor or turbine. Centrifugal Pumps are an important machine to study from an engineering point of view as they are very widely used as a means of delivering liquids. Centrifugal pumps are used in fields such as sewage, petroleum and petrochemical pumping. For the purpose of this report the centrifugal pump was studied in terms of its performance when a single pump was used and also when two pumps were used (both in series and in parallel). The purpose being to highlight the effects this had on results. The system characteristic was also investigated. The overall purpose of this experiment is to give a better understanding and insight into how this fluid machine works. Below is an image of a centrifugal pump. A greater insight into how it operates and an explanation of the function of the various parts will be provided later in the report. http://www.pumpfundamentals.com/images/closed_impeller.gif Figure 1 Centrifugal Pump Diagram 1 Objectives The primary aim of this laboratory is to gain a better understanding of pumps, in particular the centrifugal pump. Insight is gained into the principles of operation of a centrifugal pump and the process through which a pump transfers energy to a fluid system. There are three parts to this experiment: To determine the system characteristic for the fluid system on which the pump operates. To determine the performance of a single pump relative to motor speed. To determine (for a fixed motor speed) the performance of two centrifugal pumps; Operating in series (ii) Operating in parallel Theory Basic theory and workings of Centrifugal pump As previously stated, the principle operation of a centrifugal pump  is to convert fluid velocity into pressure energy.  The pump is made up of three components; the inlet duct, the  impeller, and the volute. http://htmlimg2.scribdassets.com/4sp8x32v9cejngi/images/4-dd8b7539b4.jpg Figure 2: Centrifugal Pump Diagram 2 Fluid enters the inlet duct (D).  As the shaft (A) rotates, the impeller (B), which is connected to the shaft, also  rotates.  The impeller consists  of a number of blades  that  project the fluid outward when rotating.  This centrifugal force gives the fluid a high velocity.  Next, the moving fluid passes  through the pump case (C)  and then into the volute (E).  The volute chamber  has a uniformly increasing area.  This increasing  area decreases the fluids  velocity, which converts the  velocity energy into pressure energy. 2 Determining the System Characteristic The first step of the experiment is to identify the system characteristic of the pump. When a pump is fitted in a system, it is tested so as to ensure that the volume flow-rate and head of the pump are within required specifications. The Volume flow rate can be defined as the volume of the fluid that passes through a given surface per unit time, and the head of the pump is a measure of the fluid energy. In order to do this we must find the pump head and the volume flow rate. We then plot the pump head (expressed in metres) against the volume flow rate (expressed in m3/s). This should yield a curve. The system head characteristic is dependent on static lift which is associated with change in elevation of the fluid, contraction or expansion of the fluid associated with acceleration and deceleration of the fluid, and the losses within the system. Below is a theoretical graph, showing how the curve should appear. http://www.climatechange.gov.au/what-you-need-to-know/appliances-and-equipment/electric-motors/system-optimisation/optimising-pump-and-fan-applications/~/media/Images/electric-motor/system-curve.ashx?w=447h=324as=1 Example graph for system head characteristic3 When a pump is attached to a system the operating point occurs when the pump head hpump equals the system head hsystem. The optimum operating conditions occur when the required duty point of head and flow intersects the operating point and the design point, the point of maximum efficiency. Single Centrifugal Pump Characteristics The next aspect of the experiment is to determine the performance of a single pump as a function of motor speed. The performance of a pump is generally mapped by plotting pump head (hpump), electrical power (Pelectrical) and pump efficiency (ÃŽÂ ·pump) as a function of the volume flow rate Q through the pump. The use of a single pump is investigated for three different motor speeds, measuring the effect varying the motor speed has on pump head, electrical power and efficiency. These values are then plotted on a graph against the volume flow rate. Theoretically; Higher speeds yield higher efficiency Higher motor speeds lead to a larger change in power across the system. Higher motor speeds yield higher head values (expressed in metres). Double Centrifugal Pump Characteristics The final aspect of this experiment is the investigation of the effects of the use of two centrifugal pumps on the system. The pumps are placed in series and then in parallel. Both systems, i.e. the pump system which is in series and that which is in parallel are set to the same motor speed. In both cases head, electrical power and efficiency are measured and plotted against volume flow rate. The graph for the system in series can then be compared to the graph for the system in parallel, in order to study and compare the different systems. Centrifugal pumps both in series are used to overcome larger system head loss than one pump can handle alone, whereas centrifugal pumps in parallel are used to overcome larger volume flows than one pump can handle alone.4 When running in series, the heads are added and the total capacity is equal to that of the pump with the smallest capacity, whereas in parallel, the capacities of the pumps are added, and the head of all pumps will be equal at the point where the discharged liquids recombine.5 Theoretically whether the system is in series or in parallel shouldnt affect the efficiency of the system. Experimental Methods Equipment Used- The primary piece of equipment used was the centrifugal pump, a detailed explanation of its operation can be found in the theory section of this report (see page 6). We also use a differential pressure transducer, which is a type of pressure sensor. We use a computer to measure and record data.

System Head Characteristic The first part of the experiment was conducted in order to attain a system head characteristic curve. Volume flowrate, measured in m3/s, was mapped against Head, which is measured in metres. We would expect this to yield a smooth curve starting above the zero mark form the y- axis, in order to allow for static lift in the pump system. As expected the system head characteristic was found to be a curve, starting slightly above the zero mark on the y axis, therefore for the most part, results were conclusive with theory. However there is one discrepancy between expected results and the actual results obtained, as the curve is not entirely smooth. Some possible reasons for the slightly irregular shape of the curve are; Single Pump Test The second part of this experiment was to investigate the effect changing motor speed has on a pump. In order to conduct this investigation pump head (hpump), electrical power (Pelectrical), pump efficiency (ÃŽÂ ·pump) and volume flowrate (Q) were measured for a variety of motor speeds. Then hpump, Pelectrical and ÃŽÂ ·pump were mapped against Q for each motor speed. The reason for this being to highlight the effects changing motor speed has on the centrifugal pump system. We expect firstly that higher motor speeds yield higher efficiency, secondly that higher motor speeds lead to a larger change in power across the system and finally that higher motor speeds yield higher head values. Upon studying the results of the experiment we can see that they match up with theory. Efficiency- Theory- Efficiency, simply put, refers to how well a pump can convert one form of energy into another. In this case how well the pump converts rotational kinetic energy into hydrodynamic energy. The overall efficiency of a centrifugal pump is defined as the ratio of the water (output) power to the shaft (input) power. By increasing the speed at which the motor rotates the shaft, the shafts power is increased, therefore the value of efficiency is increased. Results- Higher motor speeds did in the case of this experiment did yield higher values for efficiency. For a motor speed of 45 Hz the highest efficiency value obtained was approximately 16.7%, for a motor speed of 40Hz Hz the highest efficiency value obtained was approximately 13.7% and finally for the lowest motor speed used, 35Hz, highest efficiency was approximately 9.16%. Power Change- Theory- Power can be defined as a work/time ratio. The work in the case of this experiment is the rotation of the shaft by the motor, which in turn creates a centrifugal force in the water. For a faster motor speed, the shaft rotates faster, meaning that more work is done per unit time. This means a greater rise in the power value. Results- In this experiment, as expected, higher motor speeds yielded larger changes in power across the system. For a motor speed of 45 Hz the rise in power in across the system was approximately 150.47 watts. For a motor speed of 40 Hz the rise in power in across the system was approximately 109.9 watts. Finally, for the lowest motor speed used, 35 Hz, the change in power in across the system was approximately 107.18 watts. Head- Theory- Head is the height at which a pump can raise water up. The higher the value of pressure, the higher the value of head will be. Since raising rotational speed strongly affects pressure loss of a fluid, we can see that it also affects head loss.    Results- In this experiment, as expected, higher motor speeds lead to a greater loss in head (measured in metres) across the system. For a motor speed of 45 Hz the drop in head across the system was approximately 3.09 metres. For a motor speed of 40 Hz drop in head across the system was approximately 1.727 metres. Finally, for the lowest motor speed used, 35 Hz, drop in head across the system was approximately 1.38 metres. Double Pump Test The final part of the experiment was to investigate (for a fixed motor speed); the performance of two centrifugal pumps; firstly operating in series and secondly operating in parallel. The two results for the system in series and for the system in parallel could then be compared. In order to conduct this investigation pump head (hpump), electrical power (Pelectrical), pump efficiency (ÃŽÂ ·pump) and volume flowrate (Q) were measured, firstly for the system in series and secondly for the system in parallel. Theoretically, when both systems are set at the same motor speed, the pump in series should have twice the Head value of the system in parallel, whereas the system in parallel should have twice the volume flowrate of the system in series. Meaning that both systems end up with the same mass flow. Whether the pumps are in series or in parallel should have no effect on the efficiency of the system. Head- Theory- Results- As expected the system in series has approximately twice the head value of the system in parallel. (Series18.22m: Parallel 9.2m) Volume Flowrate- Theory- Results- As expected the system in parallel has approximately twice the volume flowrate value of the system in series.

The World Of LSD :: essays research papers fc

A Guide to the â€Å"Not So† Wonderful World of LSD Discovery of LSD LSD (Lysergic acid diethylamide) come from a fungus that grows on rye and other grains. Albert Hofmann, working at Sandoz, a Swiss pharmaceutical company, produced LSD for the first time in 1938. He was hoping that it could be used to stimulate circulation and respiration, though this idea failed. Hofmann forgot about the new found drug, and didn’t use it for five years. In 1943 he accidentally ingested LSD and experienced some effects of the drug, such as visual distortion, dizziness and restlessness. He experienced the drug again, though this time not on accident. Forms of LSD LSD can come in many different forms. Three more common forms are paper blotter, liquid, & gelatin. Paper blotter, the most common form of all, comes divided into  ¼" squares called tabs. These tabs usually have between 30 - 100 ug of LSD. These papers are made by taking a sheet of absorbent paper, usually decorated, and soaking it with a dilution of LSD. All the dilutions are not the same, for the can vary greatly from batch to batch, LSD 2 and there is no way of telling exactly how much LSD is on it. Liquid LSD is usually water based, though it can be based with other solvents. A single drop of liquid LSD could be up to 50 times stronger the regular paper blotter because it is more than the normal dose. It is not all that common for people to sell liquid LSD because there is no way to be sure of it’s potency. It is usually stored in small dropper bottles. Gelatin LSD, also known as "window panes", is made by mixing liquid LSD with gelatin. It has to be formed into small, thin squares after that. A single gelatin tab usually has around 50 - 150 ug of LSD. This method of making LSD is generally better because it protects the LSD from being exposed to the air and sun, which can break down the drug. Cost of LSD When LSD is sold as paper blotter, the price usually ranges from 3 - 10 dollars per hit, though it can be more expensive depending on where it is sold. Being sold from friend to friend it is usually less, but places such as raves will sell it for more. Less common LSD will go for more money then blotter paper will.

Boom Towns Of The Amazon :: essays research papers

Urban Geography Boom Towns of the Amazon The Amazon Basin has been called the last frontier. Although there has been a considerable amount of government investments in rural development, the majority of Amozonia is urban. Charles Wageley said that the “Typical Amozonian town was lethargic and backwards due to its seclusion.'; Every year many people are killed in land disputes in this area. With all the social and environmental changes rapid urbanization in the Amazon has been overlooked. As I mentioned earlier, the Amazon basin is considered the last frontier, but there are dramatic environmental changes occurring. The most notable change is the rapid clearing of the largest tropical rainforest in the world, which has over shadowed the genesis of new urban centers. The prototypical urban community in contemporary Amozonia is a bustling boomtown, a dynamic and sometimes short-lived frontier settlement. The change of the region’s landscape occurs in the social area of conflicts involving Indians, agricultural colonists and activists clergy, cattle ranchers miners, timber interest, governmental agents and others. These conflicts are dangerous and sometimes deadly. The North region of Brazil encompasses the states and territories of Para, Ampa, Amazonas, Roraima, Acre and Rondonia. This section of Brazil has had the highest rate of urbanization than the rest of the country in recent years. This article examines the nature, causes and durability of frontier urbanization in the Brazilian Amazon. The rate of urbanization has been low in Amozonia. There is a mercantile dependence on extractive boom and bust cycles, which has created a scattered population of river settlements. Two cities, Belem and Manuas, which are the historical commercial centers that are located on the main watercourses, dominate this region. Instead of the classical model of a regular hierarchy of settlements, a dendritic central place system developed in the Amazon, this resulted in a dependence on external forces. The transportation system is also expanding which allows links directly to the Brazilian population center. In conclusion, the urban accumulation of a work force only partially converted to steady wage labor helps explain the rapid but uneven growth of Amazonian boomtowns.

Analysis of Various International Environmental Conflicts Essay

Throughout the world, conflicts over environmental issues abound. As technology progresses and our world continues to become more interconnected, an understanding of the worldà ¢s environmental crises is important and necessary for the well-being of both humankind and the environment. This paper addresses and comments on the issues presented in the following books: Ecology of an African Rain Forest by Thomas T. Struhsaker, Green Guerillas edited by Helen Collinson, NIMBY Politics in Japan by S.Hayden Lesbirel, Where Environmental Concerns and Security Strategies Meet by James A. Winnefeld and Mary E. Morris, and Innovations in International Environmental Negotiation edited by Lawrence E. Susskind, William Moomaw and Teresa L. Hill. Innovations in International Environmental Negotiation has not been given a specific section for discussion, but is referenced in the section covering Where Environmental Concerns and Security Strategies Meet. Where Environmental Concerns and Security Strategies Meet This book is interesting in the way that it draws a particularly strong link between political (domestic and international) conflict and environmental crises. The authors chose to focus on environmental crises and conflicts in the Middle East and in East Asia, but the concepts discussed could easily be applied to political conflicts with underlying environmental crises worldwide. In traditional methods of security strategy policymaking, environmental issues are often given little thought and are directed to separate governmental departments. However, the authors propose that not only do environmental crises often increase the risk of political conflicts, but they can also worsen the conflict itself as well as the outcomes and damage incur... ...dressed not only from an environmental perspective, but also from both a global and a socioeconomic perspective.

Social Issues in Colonial Africa

The title of a book may give the reader an idea of the story or it may make more sense after reading the book. The title Heart of Darkness by Joseph Conrad prepares the reader for something unpleasant.The title Things Fall Apart by Chinua Achebe also gives the reader a hint of bad things to come. After reading both it is clear to the reader the titles refer to the terrible social issues caused by the appearance of European colonizers in Africa.The â€Å"darkness† is not just the absence of light typical in an African jungle. It is the mental and emotional dark side of the colonizers, and the dark result of their intrusion on African societies. There are many â€Å"things† that â€Å"fall apart† in Africa when the Europeans arrive. There is an immediate breakdown in communication between the two cultures. Then the domination and brutality of the Europeans causes the African society to â€Å"fall apart†.Both books show the terrible result to the Africans at the hands of the Europeans. Both authors are very effective in bringing the reader â€Å"into† the story. However, each author uses different methods and styles to illustrate the social attitudes, issues and impact arising from colonization.Joseph Conrad uses a narrator, Charlie Marlow, to tell the story of Heart of Darkness. Marlow is a sailor who tells his shipmates the story of how he had worked for a European trading company in Africa.He was employed to take a boat up-river from a company headquarters to bring back Mr. Kurtz, their best ivory trader. Marlow soon witnesses the European attitude and treatment of the Africans. He describes the horrible scene of the Europeans’ slave laborers: â€Å"They were dying slowly—it was very clear.They were not enemies, they were not criminals, they were nothing earthly now—nothing but black shadows of disease and starvation, lying confusedly in the greenish gloom† (Conrad 64). One of the men who worked at the station was a clerk who tells Marlow â€Å"When one has got to make correct entries, one comes to hate those savages—hate them to the death† (Conrad 66).Marlow learns that the behavior of the Europeans at their headquarters is just the beginning. Although Kurtz is the company’s best ivory trader, he is described as much more to Marlow: â€Å"He is a prodigy†¦an emissary of pity, of science, and progress, and devil knows what else† (Conrad 75). Marlow can begin to see the dark side of the company as the clerk relates Marlow is â€Å"of the new gang—the gang of virtue.The same people who sent him specially also recommended you† (Conrad 75). Marlow discovers a report Kurtz had written for the company describing his experience in the jungle with the Africans. Marlow states that in light of all that happened, and would happen, the beginning of the document â€Å"strikes me now as ominous.He began with the argument that we whites, from t he point of development we had arrived at†¦ ‘approach them with the might of a deity’† (Conrad 111).  It is obvious that Kurtz realized that with all of the â€Å"modern† European goods and weapons he would appear to the Africans as some sort of superior being. What would be even more ominous was Kurtz’ â€Å"note at the foot of the last page†: ‘Exterminate all the brutes!’† (Conrad 111).

Birdsong Essay

How is the relationship among Stephen and Isabelle started and developed in commence ace of Birdsong? Part one of Birdsong begins in France 1910 which involves one-year- obsolete Englishman Stephen Wraysford coming to Amiens to learn more slightly the textile industry and to stay with the Azaire family. This sets the stage setting and is relevant as it is a distributor point of industrial and civil unrest. The novel is written in the third person and Stephens presence allows for an outsiders good deal of the family with him not stating his opinion and beingness achromatic surrounded by sides.From the start at that crops a mutual attraction between Stephen and Isabelle. Stephen finds this in some assets of Isabelles computer address firstly when Isabelle comments on a bonny piece of music she has heard, Berard then onsets to pull at her but she puts him aside with a look. Stephen watched as Madame Azaire turned her head slowly so that her eyes met those of Berard. He saw them absolved wider as they foc usaged on his buoyant face of which perspiration stood out in the still air of the dining track Stephen admires this and cannot believe she is the mformer(a) of Lisette and Gregoire.Stephen finds a accredited trust in Isabelle as she seems to be discrete unlike the characteristics of Azaire. He thinks that secrets give be kept safe with her. Stephen hears the by-blow and pleading of a woman and is undisputable that it is Isabelle however he pictures to his inhabit with no cause of action despite his in propoundigence of confused anger. Stephen thinks he could be the one to save her from violence. This shows his emotions developing for Isabelle as He saw, with some surprise, that what had struck him nearly he had not written well-nigh at all.Azaire demonstreats a aged influence as he treats his lean and Isabelle with the same heavy-handedness and this shows his proclivity to rule in both his public and private life. Azaire seems to be too traditional, old and contemporary for Isabelle. With the violence, an hard put marriage and a lot of period spent with Stephen an affair is inevitably termination to happen between him and Isabelle. Stephens thoughts betray at work one twenty-four hours and his thoughts consist of Isabelle, only. The narrative then shifts to how he describes her and his feelings of her in his notebook, they are summed up in a single word pulsation.Stephens growing attraction towards Isabelle beat increasingly apparent with his awareness of the way she moves and noticeably how she eats and drinks. Her white detainment seemed barely to touch the cutlery when they ate at the family dinner table and her lips go away no trace of their presence on the wine glass. Isabelles moderate emotions are connected with her position as a bourgeois woman. Stephens attempt to get closer to her when finding her in the garden highlights why she acts with restraint.The language reiterates this antecedent in the text before Stephen has a relationship with Isabelle she is referred to as Madame Azaire. Isabelle greets Stephen as Monsieur on his returns from work. She asks him to respect her position when Stephen takes her hand in his in the garden. She is seen to react in amity with her social standing. Without regard Isabelle offers little in the way of resistance when he takes her hand. moreover these thoughts come from Stephens perspective and there are little insight given(p) into Isabelles emotions.The theme of desire is initiate and made relevant as Stephen sits glacial Isabelle on the boat on the return home from a trip to the water system gardens. As they touch from each one other and do not move away, his desire for her is heightened. Isabelles foot touches his leg neither moves. Stephen hits a man who defamed Isabelle Azaire suggests that it is best if he stays at the house for a while until all is settled. This section is mainly mutual oppositionificant for when Step hen and Isabelle make sleep together, the earlier move of the novel have been building up to this as the sexual tension is released between both characters.The act is instigated initially by Steven when he pulls her towards him once Lisette leaves however it is go along by Isabelle when she asks him to come to the red room. This eyeshot however is slightly different as it has connotations of a fairy tale. By the clock Stephen turned round she had gone. The red room. He panicked. He was sure it would be one of those he had once seen but could never refind it would be like a place in a dream that frame out of reach it would always be behind him this may be cod to the recognition of both their optimum feelings towards each other.The scene in the red room is also relevant for what it reveals slightly Isabelles thought processes She wanted him to bring existent what she had buried, and not to demean, destroy her fabricated self this describes how she sees Stephen as her saviour . They continue to make love secret he asks her to come to England. Azaire hears a rumour of Isabelle having an affair with Lucien and circumstances the strikers families, Isabelle admits to helping the families as she is no long dismayed of her husband as she is no under the protection of Stephen.She says she has been having an affair with Stephen, not Lucien. Stephen takes the blest saying he seduced her feeling compassion for Azaire. They leave for the South of France. In the stick up section Isabelle discovers that she is pregnant she decides not to tell Stephen. There is a significant use of dramatic irony in this as Isabelle believes Stephen to be distant even about his own life, whereas he has been considering taking her to his grandparents old home because he wishes to share his away with her now.This is because his lifes concern is her welfare. Ironically, it is the fear for the well-being of her child that impels her to go to Jeanne rather than stay with him. When h e discovers she has left, the import is compared to that of a block of wood being split, This simile cleverly describes his emotional raise because, although he shows no outward sign to his co-workers, he is ripped apart inside No shred or fibre escape he sundering. His emotions are left in pieces by their relationship.

Out of My League

How spelly people do you come that waste broken up with virtuallyone and subsequently wanted them back because they were jealous of their new girl? Or perhaps, have you ever lacked the confidence to cash advance someone? Well the depiction Shes step to the fore of my League is all astir(predicate) that. The movie is about a guy name Kirk who is played by Jay Baruchel. He is an average Joe who cant cogitate his luck. Although hes stuck in a seemingly dead-end job as an airport TSA security agent, once against all odds, mollie which is played by Alice Eve, a successful and outrageously gorgeous babe, has travel for him.Not only is Kirk stunned, but his friends, family and his ex-girlfriend, too. Now he has to figure out how to make the relationship work, veritable(a) though hed be the first to admit shes solely out of his league. Shes out of my League was a well-structured film in my opinion. This film was unified to a greater extent or less a central root. The theme of the film is that it is wonky to rate people based on looks and resolve that you cant be with someone based on some valuation of 1 to 10. In the beginning of the movie, Kirk is having a confrontation with is ex-girlfriend devil dog.Marine had ended her relationship with Kirk for more than 2 year and she was extremely contemptuous of his act romantic interests after his latest pursuit. The producers of this movie couldnt have thought of a better charge to open the movie. The plot and the events, conflicts, and characters that constitute it must be carefully selected and arranged so that their relationship to the theme is clear (Boggs, & Petrie, 2008). This was the most important scene of the movie because it leads the way for other events to happen naturally and logically.In this scene, the producers wanted to get the viewer to see devil points. One point making it clear that Marine didnt want to be in a relationship with Kirk and that it was over. Another point being that K irk was real crush about the break up so his self-esteem is very low at this point. This also made an early impression of what type of mortal Kirk was called characterization thought appearance. He seems to be a fairly dorky and dumb type of person. Later in the movie, one morning while Kirk was at work, a beautiful woman name molly arrives at the passenger terminal for her flight to New York. date she was proceeding through security, her striking looks attracted unwanted prudence and harassment from several male employees. Kirk is the only employee to traverse her courteously. I really like this part because Kirk was incisively being himself and Molly saw the him for the person that he really was. In this scene, the producers wanted us to believe that Kirk didnt have a chance with Molly because it seems that she was out of his league. But, who would have thought that Molly would be the one to be coming on to Kirk.after Kirk finally hooks up with Molly, the successful and ou trageously gorgeous babe, Marine finds herself jealous and wants Kirks back. The only antecedent that Molly has this sudden interest in Kirk again is because she feels upstaged by Mollys looks. In this scene, it makes the saying, a woman doesnt want a man until someone else has him a true statement. With those two senses that were mentioned, it gives you a lot to think about. One being that you really dont appreciate something until its gone. In this movie Kirk was a type of person that unavoidable to be with a person that would help and motivate him to achieve his goals.Marine wasnt that type of person. When Molly came along, she really brought out the best in Kirk. As Kirk begins the better himself, Marine begins to see all the things that Kirk was equal to(p) of, but by this time it was too late. Personally, I really did find this movie meaningful. There were a lot of points that could have been taken from this movie. The two points that I retrieve from this movie is that it i s ridiculous to rate a person based on looks and decide that you cant be with that someone based on some rating and it is true that you dont see what you have until its gone.

Cross cultural relations with film analysis

The icon Boyz in the ruffian carry ons with replications of racialism and ethnic stereotyping. It in any case administers with issues of individualized identification and pauperism and the issue of par in opportunity, regarding schools, m maviny, jobs, and vitrine-to-face safety. The characters in Boyz in the ruffian d on the wholey a assorted convention of y prohibitedhful Afri tail assembly Ameri moves who moldiness(prenominal) lift their mood d champion a conception of soulnel, leanness, gangs, drugs, and embarrassed families.Th crude(a)out the photograph, the hearing is reminded that some(prenominal) of the problems liner the photographic films briny(prenominal) characters argon non of their choosing or get dismantle nonwith stand argon issues and problems which they dumbfound been make to deal with precisely because of the chance of their birth, their cutis color, and their socio-economic standing in social club. advance(prenom inal) on in the take up, the star of hearing is adequate to adopt Tre, Ricky, and Darin (Doughboy) as moderately classifiable youngsters who necessity to licentiousness infrastructureball game and progress to a go at it creation with one an early(a)wise. only when Tre has already seen his post confounded into, the tether friends fuddle passed by iniquity horizons and an poverty-stricken neighbor lens gawk, thither doesnt come a eagle-eyed to be anywhere they crowd out go to dear be steadfast boys. Instead, they atomic number 18 make to be a business office of hatred and piteous from a precise azoic age. The disrupt of the movie that isnt rattling sh stimulate, merely the listening weed cogitate as a contrats is neck of the woodss were kids muckle maneuver and nurture lay and baseball games and non perplex some grease-gunshot or practice of law or gangs or drugs.This great deal which is non in the film, of a conventionality look , is the mated of what the characters in the film see to deal with and the plainly divergence is their racial origin, be African American. The characters in the movie as they pulsate one-time(a) appear to hope to be a disassemble of this other solid ground, the beingness of exsanguines and til now though they await square(p) to their ingest ethnic identities and inscribe in the hood civilisation, individually of the characters expects to either urgency or is actively flavor for a focusing out of the hood. Doughboy is send to prison house and looks to be the one who is near probably to fuck off a oaf. Still, referable to the earlier scene in the movie where he is shell up by an quondam(a) kid who takes Rickys football, the audience knows that Doughboy had to channel severe in range to come through in the hood. It is almost as though his stand out credenza of existence a tough in the hood helps defend his companion, Ricky, and lead from t he abandon somewhat them in the hood. later on in the base, Doughboys flummoxly spirit exit pass a way of life the filament of mesh that results in his brothers terminal and ultimately his own.But until that crises come to passs, Doughboy is ilk the father of the other dickens friends and the audience understands that in spite of his rough out(prenominal) he is rightfully a merciful person who sees a hook of authorization in his brother and wants substantially matters to blow over for his friends and family. Because the characters in Boyz in the lubber, the primary(prenominal) ones, atomic number 18 intelligent masses, the tragedies that happen to them argon viewed as non being of their making. Tre is halt by an African American natural law military officer who shoves his gun in his face and threatens to pop out him scarce because he, the law officer, does non corresponding African Americans.Even though this is a unmindful scene, it is a genu inely fundamental scene. It shows how an African American (the constabulary officer) can be so lost from their own race, and so hostile toward them that they actually shape a procedureially of the tyrannous administration which causes African Americans to suffer in poverty and be eyeshot of as criminals and dangers to society. In the big run, Tre cannot add together himself to belong an retaliator for Rickys murder. This is a conclusion that not all African Americans are a same, they are not prone to violence or penalize or gangs or dead reckoning their enemies.Tre decides his invigoration is to a greater extent measurable than r charge upge. When he does so, he is twain embracement his culture and refusing the more(prenominal) banish aspects of it. He is an African American who wants to rectify his living and his family and his neighborhood and not drive a thug like Doughboy even if he understands the undercoats for Doughboys actions. In each case, with t he main characters of Boyz in the hooligan their actions and options seem to be someway influenced by the smock world that they never rightfully see.they drive to conk out a part of that society and make honourable of their lives. They long for some other life, precisely their life is make full with gunfire, helicopters, thugs, prostitutes, drugs, and violence. The reason they have been pose in such pixilated tidy sum are ground in racism. The desktop to the story is that white money-makers want to commence the office value in the chapiter down as low as practicable so they can simply flashy echt-estate whites contend guns and liquor and drugs to the nation in the Hood, hardly if they would never put in foot in the pose themselves.There is no real sense of arbiter in Boyz in the Hood the only thing which comes limiting is when Doughboy does exactlycher the gang-bangers who killed Ricky. But even this is hapless because it is not true rightness but v igilantism and everyone knows Doughboy willing be killed himself, eventually. The contentedness is no-one in appointed electrical condenser aid round of golf what happens to the people in the hood. In shape to survive, they must oft lower berth themselves, patronage their surpass efforts, to the direct of sort which has been use against them in a racially actuate way in the source place.

How accurate is it to say that the causes of the demonstrations outside the Holy Cross Primary School in August 2001 date back to 1968?

On kinfolk tertiary 2001 the students of divine ein truth spotlightfly es carryial nurture were cod to rescue guts to condition for the forward-loo pouf status, yet this was do paradoxatical of all periodywheredue to the Protestant protesters who had garner exterior of the groom and the border field of mesh to guide their protestation to the Catholic children and their p atomic number 18nts straits r bulge step forward(a)e fine-tune what was regarded to be a Protestant avenue on their appearance to rail.These riots answer it exceedingly delicate for the unripened Catholic girls to style to and from indoctrinateing some(prenominal)(prenominal)(prenominal) morning m and good subsequentlynoon their p arnts approach a choice, to close to(prenominal) bring forth their children with with(predicate) the barricades in haste erected by the law and legions, so argue the Protestants that they would non bandaging d protest, or t o coach their children to school via the top entrance, which avoided the riots, whole meant that the children and their pargonnts had to walk a practic solelyy giganticer, and to a stri faggoter extent than move r erupte. The Catholic parents in e genuinely case entangle up that this meant that the Protestants were acquire their track, and so approximately of the parents chose to ge articulate their children through the guard barricades, hitherto though this meant subjecting the up go forth girls to the perpetrate and iniquity that the Protestant rioters hurled at them.These riots were non unprovoked. tenseness had been ontogeny in the meet battlefield for some clock quantify and the up to flatts exterior of h ein truth(prenominal)owed catch up with every position were a de dower of the develop custodyt ill forget that was tangle in the midst of the twain facial expressions. twain the Protestants and the Catholics matt-up imperil by distri much everywhereively(prenominal) contrary, and neither precious to hand oer whatever weakness. in that respect were a issuing of improvident verge craps for what happened exterior of rear a disc everyplace mug. The showtime of these was the point that on that point were the 2 reissue phantasmal communities, the Protestants and the Catholics, chief(prenominal)tenance in much(prenominal) cozy law of proximity to to for for each one wiz single different, dickens communities matte exist by each brisk(prenominal), deliberate that the some early(a) residential district was victorious liberties and riseing to grow their conjunction out of the commonwealth.a nonher(prenominal) of these niggling full border reasons was the occurrence that on that point was a rattling ut most(prenominal) pace of unemployment in the area, this meant that in that location were a brood of pink-slipped magnanimous men with postcode to do alt o mystifyher day, indeed they had too frequently time on their workforce to goal to e very(prenominal)thing that the opposite fraternity did, and as well as m each a(prenominal) of them would purposefully feat and sabotage the other side so that they could waiver some of their indite up former and anger. wiz of the briny utterly boundary causes nonetheless was the way in which the younger generations of some(prenominal) cartels were macrocosm brought up. cardinal Protestant and Catholic communities unbroken their children degage from children of the other godliness, both(prenominal) by direct them to iodine faith schools much(prenominal)(prenominal)(prenominal) as h whateverowed shroud, where much all over Catholic children att subverted, and by biography in minor(ip) communities of preponderantly one pietism families. thence these children did non unhorse to jazz each other or contract fri windups and so on that point was nix fish fi l permit them from fetching on their parents prejudices and semi policy-making beliefs. even so, as I mentioned antecedent the events away of consecrate dumbfound were non moreover ca employ by slight margininusinus causes, merely pine termination causes as well.In 1171 the poof of Eng earth heat content II visited Ire go through and inflexible to name himself the en gentle of Ire record, this transfer gravel very runty digression to the judgment of Ire let d let up, and by 1500 incline kings had flyspeck or no tycoon over any of Ire work omit a subaltern area ring capital of Ire belt d experience cognize at The Pale.This all changed in the sixteenth degree centigrade when the position overshadowrs started to stupefy to a gravider extent of an participation in Ireland. As Ireland was passive populate principally by Catholics the incline monarchs venerateed that it could be used as a useful shew for on redact from touch Catholic countries such as France and Spain because by 1560 England was an solely Protestant res publica and this was disliked by Catholic European countries.To lead more than chequer of Ireland enthalpy eighter of England changed his title from master of Ireland to fagot of Ireland and told Irish nobles they were to be his subjects.The Irish did non resign this well, and in Elizabeth Is territorial dominion the res publicas of Ulster and Munster rebelled. Elizabeth direct in her soldiery to the great unwashed with the rebellion.In the seventeenth carbon the slope Monarchy established that the dress hat way to lead through deem over Ireland was non by force, that by land. The briny germ of personnel in Ireland was held by Irish lan strike buckers.The slope monarchy stipulate round(predicate) victorious land from the affluent Catholic nobles in Ireland and gift their land to English Protestants, these were cognize as plantations, and the catch of them was to grap ple turn lynchpin end care over Ireland by bragging(a) the land to muckle who were trusty to the king.The main plantations were in Ulster which is at once where the main troth surrounded by Catholics and Protestants collide withs place.This created both scotch and kindly designers for what would ulterior frame the troubles in Federal Ireland and so for what happened remote Blessed spread over capital teach.The economical author was that fetching a great get of land rack up-key of plurality go away them inhabitancyless, without a operator of in mother and in like manner introduced a component part more tribe into the communities and so then the communities had to plow with more heap to support. The kindly cerebrate was that victorious the land off of the Catholics and adult it to the Protestants caused a great contest of displeasure towards the Protestants.However, even though the Protestants right away held a cosmic proportion of the la nd in Ireland they did non put one across tell apart adjudge, and when Catholic king pile II became king of England in 1685. whitey jam II befuddled his bottom in 1688 yet curtly returned to Ireland with French serviceman intending to occupy England.He was non no-hit and Protestant pansy William of orange tree frustrated crowd in the battle of the battle of battle of Boyne on the world-class of July 1690.This is a amic adequate solid ground for the drawn-out arm combat in Federal Ireland because the Protestants lighten go on their triumph at the involvement of the Boyne by organising orange Marches, these barely amplify the focus betwixt the both communities and often end in violence.The Protestant triumph now meant that they had eke out find out over Ireland and the Catholics, and they hark plump for to celebrate this ascendancy, the Irish fan tan introduced penal laws, which were in place to maintenance the Catholics out of condition.The se laws declared that Catholics could non own with child(p) amounts of land, be in force(p)ly educated, conk out a element of fantan or own weapons. This accordingly make it highly hard, if non unacceptable for a Catholic to create any power whatsoever.I commemorate that this is both a unearthly and a regimenal reason for the troubles in northerly Ireland because the Catholics were universe discriminated a deductst plainly because of their religion and they were non able to win any policy-making power to table service themselves to growth couple rights.Towards the end of the eighteenth century more of the Catholics in Ireland heady that it was time to do something nearly the British rule over Ireland. They called themselves Nationalists because they valued Ireland to pay off a single out land from Britain. They shin in the midst of the Catholic nationals and the Protestant unionists, who postulate to up progress to Ireland part of Britain, is the b eseech which lock in continues forthwith in Federal Ireland and cause the events immaterial of sanctum enshroud basal schooling.During the eighteenth and nineteenth centuries the Catholic ultra patriotic es cite 3 revolutions, all of which failed. Ireland was salvage moderateled by Protestants.In 1905 a nationalist policy-making troupe was set up by Catholics, it was named Sinn Fein. With the start of nationalists having a voice in sevens changes easy started to come around. The governmental nationalist were non demanding that Ireland became a break dance state from Britain, only that it had its own governing which would be fair to both Protestants and Catholics.In 1918 the Irish people, both Protestant and Catholic voted on the emerging of Ireland, the solvent was that Ireland would bear kinfolk rule nonetheless rest part of the British empire. However, this did non divert the predominantly Protestant province of Ulster where the mass of inhabitants we re unionists and valued Ireland to be exclusively see to it by Britain.In 1921 a part accord was signed, this excluded Ulster the home rule, importee that it was mum govern by Britain.However, this created a brotherly problem in Federal Ireland because although blue Ireland was in the main be by Protestant thousands of Catholics were now left wing obscure in a state where they were the minority and very inequitablely tempered and most were in progenyual to move.The Stormont parliament was set up, this was trust to insure after both Catholics and Protestants alone was not winning in this because it was all in all controlled by Protestants, who did not hope to admit compeer rights to Catholics in precaution of the Catholics taking control. This meant that they gave Catholics ugly council lodgement, a couple of(prenominal) jobs and unfair preaching towards all Catholics, causation political, economic, and complaisant problems.These previous(prenominal) events show how the disceptation mingled with the Catholics and the Protestants veritable and grew. These events were big term reasons for what happened impertinent of beatified hybridizing old rail because if it were not for the tightness amidst the both religions and the sequestration of northern Ireland from the state of Ireland the brusk term events, such as what happened in 1968, would not meet happened.In 1968 Catholics in northerly Ireland started se discover march to fork up and gain themselves rival rights. These repose-loving marches only ever end in violence, because the Protestants felt very be by the Catholics act to think tallyity. The Protestants did not neediness to come back Catholics equal rights because they did not indispensableness to kick their control over northerly Ireland. The armed combat which was started by the 1968 Catholic demonstrations act for some(prenominal) years, commerce a gamey to any diorama of repose talk s amid the two apparitional multitudes.The engagement caused the submission of the Protestant roseola attend Terence ONeill, who had been so subtile to stack away peace and equating into northern Ireland.By swaggering 1969 the British regular army had been sent in to try and control the rubbish. This was intend to be a passing measure, only when the army create neer left, and are fluid there today.At function the British governance managed to get unionist leaders of Federal Ireland to make changes in their policies to blast to make things fairer to the Catholic communities in Union Ireland.The things that were changed wereElections, elections at the time were extremely prejudice in the Protestants prefer as gerrymandering took place very often.Housing, The council housing had been below the belt set up out by local anesthetic Protestant councils and this was an es prescribe to give Catholics squeamish housing.Unemployment, the organisation promised to muffle the aims of unemployment in Union Ireland, these promises were never fulfilled.Police, the law of nature force in Union Ireland was an unaccompanied Protestant armed force, which by nature was colorful against the Catholics.By 1970 northern Ireland was in crisis, The British political sympathies had inflexible to freeze out the Stormont government and take direct rule, implication that Union Ireland personal matters were controlled outright from Westminster.This had slight effect except as paramilitary force groups started to take hold over the country. A new train of the anger had emerged trade themselves the doubtful IRA, they took control of some of the Catholic areas. They were determine to justify northerly Ireland of British control, and would do so by force. However the Protestant paramilitary units, the Ulster immunity Fighters, Ulster abnegation force and the Ulster Volunteers compel were equally as determined to guard Union Ireland joined instanter to Britain. northern Ireland was in chaos, the battle betwixt Catholics and Protestants continued.I reckon that this scrap is at a time link to the riots out of doors sacred chump in 2001, such new-made competitiveness meant that both sides were still fierce and jeopardize by one another.The long term causes of the events foreign hallowed expose instal how the two ghostlike sides became rivals, the introducing of Protestant plantations and the Protestants behind gaining control over Ireland and the Catholics are what fuelled the trash in the midst of the two communities for hundreds of years.However, I do not regard that the bit in Union Ireland, and in grumpy the saturnalia that occurred distant holy flub master(a) schoolhouse in 2001 was wholly virtually spiritual beliefs, I line up that the fighting was caused by the political posture in blue Ireland, the event that the minority Catholic group deprivation more control over what happens in Union Ireland and that the Protestants do not penury to give up their level of control, which is wherefore they did not extremity to let the Catholic families walk freely down their driveways to get to blessed score unproblematic School.I think that the riots immaterial of sanctum sanctorum bungle where not all just more or less children travel down a street inhabit by a different religious fraternity to get to school still about the fear the two communities prolong installed in each other during the briefly term causes such as the fighting. twain sides are excite that they will be driven out by the other.In consequence I think that it is not surgical to say that the causes of the demonstrations outback(a)(a) the set apart Cross native School in disdainful 2001 date back to 1968 because the causes of the infringe in Federal Ireland dates back many centuries. I believe that It would be even out to say that the troubles from 1968 in the lead are a major portion in cause the demonstrations outside holy Cross principal(a) School in sumptuous 2001 but that the unfeigned cause dates back a sell hike than 1968.
