Chemistry Study Guide Acids and Alkalis

Interactive Science 2B Chapter Summary | | Chapter 10 ComMon Acids and Alkalis 10. 1 Acids and Alkalis 1. Acids taste sour. Many fruits contain acids. 2. The three mineral acids commonly found in the laboratory are hydrochloric acid, sulphuric acid and nitric acid. 3. Alkalis taste bitter and feel soapy or slippery. 4. The common alkalis found in the laboratory are sodium hydroxide solution, potassium hydroxide solution, calcium hydroxide solution and ammonia solution. 0. 2 Acid-Alkali Indicators 1. An acid-alkali indicator shows different colours in acids and alkalis. It can be used to test acids and alkalis. 2. Natural indicators can be made from some deeply coloured plants. 3. Acids turn blue litmus paper red whereas alkalis turn red litmus paper blue. Distilled water does not change the colour of litmus paper. It is a neutral substance. 4. The pH value shows the degree of acidity or alkalinity of a substance. 5. The pH value of a substance can be measured by using universal indic ator, pH paper or a pH meter. 6.Low pH values mean high acidity (or low alkalinity). 7. High pH values mean high alkalinity (or low acidity). 8. Substances with pH values < 7 :acidic; pH values = 7 :neutral; pH values > 7:alkaline. 10. 3 Acids and Corrosion 1. Dilute acids react with some metals and produce hydrogen. 2. Test for hydrogen: Put a burning splint near the mouth of a test tube containing the gas. If the gas is hydrogen, it burns with a ‘pop' sound. 3. The rate of reaction of some metals with dilute hydrochloric acid or dilute sulphuric acid: maznesium > zinc> iron > copper (no reaction) . Carbonates react with acids and give carbon dioxide. 5. Marble and limestone mainly contain calcium carbonate. They are used as building materials and they can be corroded by acids. 10. 4 Safety Related to the Use of Acids and Alkalis 1. Strong acids / alkalis are corrosive. Weak acids / alkalis are generally less corrosive. 2. Dilute acids / alkalis contain a low percentage of ac ids / alkalis. Concentrated acids / alkalis contain a high percentage of acids / alkalis. 3. Concentrated strong acids and alkalis are highly corrosive. 4. Safety measure in handling strong acids and alkalis |Reason | |(a) Stick the hazard warning label ‘corrosive ‘ on the surface|To warn users about the corrosive property of the chemicals. | |of the container. | | |(b) Wear safety spectacles. |To prevent the acids and alkalis from getting into the eyes. | |(c) Put on protective gloves. |To prevent our skin from contact with the acids or alkalis. | |(d) Wear laboratory coat. |To prevent damage of clothing and body. |(e) Work in a fume cupboard. |To prevent vapours of the acids or alkalis from irritating our| | |eyes and respiratory system. | 5. To dilute a concentrated acid or alkali, always add it slowly to a large amount of water with stirring. Never pour water into a concentrated acid or alkali. 6. The first step in treating acid or alkali spillage on our body is to w ash with plenty of water. 10. 5 Acid Rain 1. Clean or normal rain has a pH value of 5. 6. 2. Acid rain has a pH value lower than 5. 6. 3. Practice test:Â  answer keyAcid rain is mainly caused by the acidic pollutant gases sulphur dioxide and nitrogen oxides. 4. The main sources of sulphur dioxide and nitrogen oxides in the air are motor vehicles, power stations and factories. 5. Acid rain may ? corrode structures made of metals, marble and limestone, ? kill fish and plants in lakes and rivers, and ? slow down plant growth and even kill plants. 6. The government, industries and citizens should work together to reduce the release of sulphur dioxide and nitrogen oxides, which cause acid rain. 10. 6 Neutralisation 1. An alkali and an acid can neutralise each other. . Neutralisation occurs when an alkali is mixed with an acid until the resulting solution becomes neutral (pH = 7). 3. When an acid is neutralised with an alkali, a salt and water are formed. The word equation for neutralisation is: Alkali + Acid (Salt + Water 4. Antacids are weak alkalis used to neutralise excess acid in the stomach. 5. Weak acids, such as eth anoic acid in vinegar, can be used to neutralise the alkaline stings of wasps. 6. Weak alkalis, such as baking soda (sodium hydrogencarbonate), can be used to neutralise the acidic stings or bites of bees, ants and mosquitoes. . Weak alkalis, such as slaked lime (calcium hydroxide) and powdered limestone, can be added to acidic soil to raise the pH for plant growth. 8. Acids in industrial wastes can be neutralised by adding alkalis such as sodium hydroxide, while alkalis can be neutralised by adding acids such as sulphuric acid. 10. 7 Daily Uses of Acids and Alkalis 1. Acids and alkalis can be used in cleaners to remove stains and grease. 2. Acids such as ethanoic acid can be used to preserve food. 3. Acids can be used to prevent the browning of fruits. ———————– [pic] [pic]

Environmental Scan Paper Essay

A business environment is made up of both internal and external factors. The environment of a business must be scanned to be able to determine what factors the company can use to determine the development and forecasts that will help in the success of the business. The definition of Environmental Scanning, as per managementstudyguide.com, is the â€Å"possession and utilization of information about occasions, patterns, trends, and relationships within an organization’s internal and external environment†. Scanning is used to identify the threats and opportunities that exist in the business environment. Some of the internal environment factors that a company must observe include; employee interaction with each other, with management, manager interaction with other managers, and manager interaction with shareholders, brand awareness, organizational structure and the main staff (managementstudyguide.com, 2012). The company may use other resources to gain this information as in group discussions, surveys and interviews. This information than may be used to identify the strengths and weaknesses of the company. External environment plays an important role as a company starts to become more competitive and changes start to occur. As these changes start to occur, it becomes essential for the company to identify what their competitors are doing. These changes may also affect the internal environment, so it is important that the company update its core competencies as per the external environment. Because external environments are always changing, the company should be ready at all times to be able to accept and adjust to the environmental changes. External monitoring could include the original forecasts of raw materials, which may affect the credibility of the original source. This will force the company to be more focused on scanning, forecasting and analysis to create a more trustworthy prediction and the input costs (managementstudyguide.com, 2012). The external environment scan should include three areas; immediate/industry environment, national environment, and the broader socio-economic environment/macro-environment. Companies The two companies that will be used in this paper will be Apple and Target. Both of these companies have survived a tough economy over the years by having to adjust to many external and internal environmental factors. Apple, as most of us know, is a successful producer of computer hardware and software. Target, is one of the largest retail companies, right behind Wal-Mart, in the U.S. The environmental scan is used to evaluate the threats, opportunities, strengths and weakness of both Apple and Target. This will help identify external and internal areas that may need help and the areas that have been successful. Strengths There are many strengths that have made Apple a success. Apple is known to offer superior products such as the iPhone, iPad, iPod and many others. They control both the manufacturing of its products as well as its operating system (http://www.slideshare.net/edbiy/swot-analysis-for-apple, 2012). Apple also produces its own internal components for the core of their products. They also set a high standard for the quality of their products to make sure that the customer is extremely satisfied. Apple is always evolving and creating new and updated products. Apple has a very loyal customer base that will buy the new and updated product regardless of what it costs. The company stock is also the highest in their personal history. Target is a monster of a company as well. As of 2011, the diversification of its store chain was at 1,750 stores. The stores are big; anywhere between 95,000 to 135,000 square feet is size. As of 2011, Target has a presence in all states except Vermont. Due to the competition with Wal-Mart to keep their product prices low, Target has seen increases in revenue year after year, with their 2011 revenue equaling $67 billion. Target has adapted to their specific demographic locations and offer three different types of stores; Target Green Lands, Super Target, and their urban stores. And most important, Target offers a wide variety of goods; clothing, electronics, beauty, and home furnishings to just name a few. Weaknesses As being the leader in the electronic industry, Apple is faced with having to ensure their product is consistent and quality is number one. Not all of Apple’s products are without flaws. With their competitors making similar devices, Apple must continue to invest in research and development, to make sure any flaws don’t hamper future success. With Apple being a financial stable company, any lack of debt could be seen as a weakness for their infrastructure as it may pose a risk for stock acquisition by other companies (http://www.slideshare.net/edbiy/swot-analysis-for-apple, 2012). As for Target, their lack of an internal presence is a weakness. Though their products are considered low cost, the quality of their product is better than Wal-Mart, which makes Target’s products a higher price than their competitor. Employee wages have also been considered low, forcing some employees to look for work elsewhere. Threats With Apple products saturating the market, Microsoft has still be able to hold a consistent share of the market as well. Within the industry, there are many competitors that appeal to the economic conscience. Companies such as HP and Dell are offering low-budget computers that are appealing to customers that cannot afford the Apple product. Apple must be able to produce their products and set a financial standard so they do not lose out on a certain market of people. Target has their threats as well. Kmart and Wal-Mart both offer similar products but at a lower cost. With today’s economy, customers may sacrifice the quality of a product to get a lower price. Target may have to restructure their product base to keep from losing out to the competition. Opportunity With Apple being a technological leader, they are known for their originality and innovative thinking. iLife is a new product that allows users to link up multiple programs through one central application. Apple has found a way to simplify a person’s â€Å"life†, by consolidating what that person needs into one little package. That is innovation at its finest. Apple will continue to develop new opportunities through innovation and breaking new ground in different markets. Target introduced that the company will expand into Canada, this being the first step into the international market. The company will focus on reducing operational cost and increasing their revenue ratio. Target will continue to push the private labled products to customers, to focus on low cost products. These companies are creating value by offering a product that is made up of tangible and intangible attributes that the customer values. These companies are able to obtain money for the costs which then generates benefits that it values. Apple and Target create products that offer many solutions for their customer. This creates a competitive advantage for these companies. Creative advantage is the â€Å"advantage that a company has over its competitors, allowing it to generate greater sales or margins and/or retains more customers than its competition† (Investopedia.com, 2012). Both companies have shown that they offer a product that has been superior to their competition, which in turn has generated greater sales for these companies. The mission statement of a company is a way to evaluate how a company may measure their effectiveness. Apple states, â€Å"Apple computer is committed to protecting the environment, health and safety of our employees, customers and the global communities where we operate. We recognize that by integrating sound environmental, health and safety management practices into all aspects of our business, we can offer technologically innovative products and services while conserving and enhancing resources for future generations. Apple strives for continuous improvement in our environmental, health and safety management systems and in the environmental quality of our products, processes and services†. Target states, â€Å"Our mission is to make Target your preferred shopping destination in all channels by delivering outstanding value, continuous innovation and exceptional guest experiences by consistently fulfilling our Expect More. Pay Less. ® brand promise†. Both Apple and Target have shown continued success, both following their mission to create a better experience for their customers. References Answers, W. (2012).

My Decision Making Model Essay

My Decision Making Model BY sals39 My Decision Making Model Experience MMPBU500 July 12, 2010 Mr. Chuck Millhollan Abstract Throughout every day of our lives we are forced to make decisions although at times it is not the easiest task. As a result, decision making models are utilized to ease the burden of making the wrong decisions which have lasting effects. There are numerous decision making models and they each function in various ways. However, my most favorable decision making process is the rational decision making process. It helps to me weigh my options as to what is my best possible choice and clearly epicts the consequences of my final decision. The rational decision making process is a six step process that is utilized extensively in many organizations and schools. The process is used so that decisions made are in the best interest of each situation. According to Janis and Mann, † in rational decision making: (a) the goals and objectives of decision makers are clear and known in advance; (b) the decision maker chooses the best alternative among all possible courses of action; (c) full information about the consequences of possible courses of action is available; and (d) there is no uncertainty involved†(Decision aking, 2001). As an elementary educator, I frequently make decisions and tend to utilize the rational decision making process as I do so. Problem Defining the Prior to any decision making process being used there must be a problem or situation on hand. The first step is defining the exact problem and it can be easily overlooked. It helps to avoid misinterpretations of the problem and uncommon solutions especially when working with others. For instance when we are conducting grade level meetings we normally begin by individual stating problems that we have been encountering individually in the classroom. We then merge those individual issues and find one root that is the cause of those issues and target it as our main problem. Research Pros and Cons In every situation after establish the problem it is then possible to research how to eliminate the problem and the pros and cons of doing such. According to the Macquarie Dictionary, when we evaluate the pros and cons of a decision we are â€Å"establishing the arguments for and against something† (Macquarie, 2010). As a result we then, formulate solutions and the good and bad of each solution. It helps us to consider every possible option and recognize consequences, if any. This in students. Making a Decision and Formulating a Plan When making decisions especially within a group it can be very time consuming and requires a lot of thought. After weighing the pros and cons one should be able to make the best possible choice that is going to benefit the situation. As we progress to making a decision in our grade level meeting we aim to come to once consensus which is normally done by taking a vote based on our findings. When then immediately begin brainstorming ways in which we can get our ideas and decisions into actions by formulating a plan. We establish our weekly plan which is a detailed escription of the daily activities and lessons that is carefully executed by all teachers within that grade level. We then schedule or next grade level meeting to evaluate the outcome of our decisions and plans to solve them. Evaluate Results Why establish a plan and do not evaluate the productivity or outcome? No matter the situation it is always of best interest to evaluate any plan put in place to rectify a problem. It is done by reevaluating the problem, the solutions that were presented, the plan that was put in place, and how well the plan was executed and succeeded in alleviating the problem. At the beginning of our weekly grade level meetings we use the first ten minutes to evaluate prior plans that were put in place and whether they were effective or not. At that point we are able to make the necessary alterations needed or express what portions of the plan was successful. Conclusion The rational decision making model help to ensure order and consistency is established into making your decision. It also provides a well thought-out and orderly approach to decision making. It helps make certain we consider all factors relating to a decision, in the most reasonable manner.

Using evidence from at least 3 domains critically evaluate the extent Essay

Using evidence from at least 3 domains critically evaluate the extent to which evolutionary psychology provides an adequate explanation of human behaviour - Essay Example 250). While other theories on human behaviour can explain some types of behaviours better than evolutionary psychology, this branch of study has credibility through understanding that the adaptive traits that are exhibited in human beings are part of a process that can explain all aspects of behaviour from an historic, and prehistoric perspective of viewing the natural adaptive development of the human species. In order to examine the effectiveness in evolutionary psychology in explaining human behaviour, universal conditions can be examined for the common responses that are seen within the species. Using evolutionary psychology as a way of understanding attraction behaviours, for instance, reveals that men and women find each other attractive based on attributes that promote the survival of the species. Women will find men with resources more attractive, while men will find physical attraction, which is associated with good health and child bearing potential, a more important attribute in potential mates (Keil & Wilson, 2001, p. 751). Part of understanding evolutionary psychology requires an understanding that the behaviours that are present within the human species are directed towards specific adaptive purposes. Vuchinich and Heather (2003) argue that addiction behaviours are the result of an evolved psychological mechanism that has been shifted in the process of drug dependence (p. 251 ). This type of exaptation allows the researcher to examine the underlying cause of the responses that an addict will have to addiction seeking stimuli. Finally, looking at the example of aggression allows for the exploration of a set of behaviours that are typically tied to responses that are more blatantly tied to evoked responses. The frustration-aggression hypothesis postulated by Dollard suggests that when faced with a frustrating stimuli that would instigate the behaviour of aggression, a

Mean Street movie analysis Review Example | Topics and Well Written Essays - 500 words

Mean Street analysis - Movie Review Example Cassavetes showed his girlfriend called Sandy Weintraub, the field and as a result decided to provide extra sage advice dubbed tone the God-disturbing angst and introduce more tales from the neighborhood (Braund Para 1). The movie is a basically about a small time wise individual called Charlie who was tormented by Catholic guilt. Other tormentors were his loose-canon best pal Johnny Boy and the coterie of cronies, was written by Scorsese and Martin Mardik travelling along the streets of little Italy in the Battered Valiant of Martin. Soaking up the recognizable pageant with fresh sight, they writers got a real taste of little Italy. Also, it spiced up the narrative with cases drawn from Scorsese’s rich background of tales (Braund Para 2). It is prudent to point out that the main pleasure obtained by reviewing the movie Mean Streets is the performance of De Niro. An eruption of casual mayhem and random violence depicts Johny Boy as an excellent reflection of fatal carelessness, a species of heedless fanatic whom cannot be doubted to cheerfully treat welching with debts to local loan offices as if it were some form of extreme sport. De Niro inventing without a net and free from thoughtful brooding that marks his future roles invests him with similar parts troubles and irresistible charm. De Niro shoulders the film manfully, but as the tool for Scorsese’s religious musings when they cross the boundary from heavy to heavy-handed, it makes people to lose patience (Braund Para 3). A significant part of the movie is characterized by documentary feel, however just like some hellish bordello, the movie is like a diabolical glow bathing everything and everyone in shades of carnal red. Such a symbolism is stunning and infinitely more relevant than Keitel sticking his hand in the closest flaming object every moment a stripper shakes before him. Scorsese’s little hood has long disappeared. It is three small

The law of international commerce is subject to increasing Essay

The law of international commerce is subject to increasing harmonization - Essay Example One can trace the establishment of trade fairs, from the Frankfurt Book Fair to the Antwerp Cloth Fair, to the 1200’s to 1400’s, at which time producers and buyers would meet on a regular basis to exchange goods for currency or promissory notes. This safe passage was ensured by the increasing influence of kings and rulers, who were able to tame warring factions and create a system of tolls, laws and enforcement which did not exist during the Dark Ages. Although it was expensive to take a trade route (the Rhine, for example, had over 40 toll stations), the benefit of security outweighed the cost for those who had high-value goods and ready markets in other areas. Trade posed some specific problems which required harmonisation relatively early on. A couple of examples will suffice to explain how these problems arose, and how they were solved. If a trader, for example, were to go to the Frankfurt Book Fair in the Spring of 1450, he might want to find books for his patrons and residents of his home area (say, Tuscany and the de Medici’s). The trader, fearing the dangers of robbery on the roads, or perhaps just lacking the resources, does not take gold with him on the long, arduous journey from Tuscany to Frankfurt. Rather, he brings along letters of introduction from his patrons. In some cases, if the trader was rich enough or well-known, he could trade ‘on his reputation.’ In either case, when he arrived at the Book Fair, he brought documents with him. If our Tuscan trader visits a stall of, say, a Stuttgart bookmaker and decides to buy a few of his books, the bookmaker would like to be paid. Since the trader didn’t have gold or silver with him, he offered to pay the bookmaker with a promissory note. This method of payment led to a series of questions: (1) how do I (the Stuttgart bookmaker) know that this person is who he says he is? And (2) what

PSY-499 Essay Example | Topics and Well Written Essays - 500 words

PSY-499 - Essay Example Pougnet, et al, (2011) there is significant difference in the cognitive command and social wellbeing of the children who have a longer and close attachment with the male parent In the development of a child from infancy, the immediate environment plays a vital role in defining the cognitive development of the child. This explains the varied behavior of children in various interactive social environments. In respect of the cardinal social input of the male parent to the child’s future behavior, children from parents who are incarcerated tend to differ marginally from the ones with their male parents around their daily life (Dick, 2011). Both the mother and the father have an influence in shaping the psychological development and maturity of the children. Finley & Schwartz,(2007) from their analytical experiments using Statistical tests of significance indicates that the mother plays primary role as far as the infant’s perception of the world is concerned. However as the child grows, the male parent also contribute immensely in his/her interaction with the new world and absorption of various concepts in life. Various scholars have explored the social inadequacies that are likely to erupt in the life of the child in the absence of the male parent. Some of the cases that may lead to this absence are also highlighted with more focus on male incarceration (Menning & Stewart, 2008). The effect of male parent’s absence is two sided in the social life of the child since there is a certain perception such children will develop about the absent fathers and this gradually alters the cognitive and moral interaction of the child in the society. The child’s language skills cannot be learnt from watching infant directed DVD’s or any audio-visual program from the media and it is this point where physical interaction of the male parent through playing with the child come in handy .Coakley,(2013) asserts that children are not able to relate visual objects with real

Art Theory Essay Example | Topics and Well Written Essays - 1000 words

Art Theory - Essay Example As such a formidable tool, visual stimuli have played an important role in both publicity and advertising (propaganda), and other forms of public art-different parts of society at different points have created art to send messages, or created art to demonstrate the beauty, the potential, or the ugliness of something. While public art exists in many incarnations, from the seemingly innocuous logo to the graffiti at the bus stop to the almost universally-identifiable swastika or cross, its careful manipulation and is an extraordinarily powerful political and economic tool. The advertising industry has capitalized on art's flexible nature, and makes billions annually off our susceptibility to the visual. Images have a long history of manipulation and an important role in propaganda. From the US Army's famous War Bonds posters of World War II to Maoist propaganda, images have been used for hundreds of years to send powerful political messages to the world's illiterate masses. The media, famous for its use of photography, has successfully changed the course of wars, stirred public opinion, ignited arguments, and evoked sympathy through skillful manipulation of images. The US Army's innovative use of artistic images and paintings raised more than XXX in War Bonds between 194 and 194 One particular poster shows a valiant nurse in a bloodstained uniform cradling a wounded soldier; in the background a fascist monster with cunningly painted green eyes lurks. The monster-in reality, probably a German soldier as young, poorly-educated, and confused as our own-is depicted as subhuman, a creature whose only purpose is to thwart American democracy and to kill our men in uniform. The artist's us e of color, context, and detail carefully and clearly fulfills his social purpose: if the Average American Citizen wants to keep these terrible killers off of our shores, he must purchase War Bonds. The War Bonds posters, thanks to this artist and a handful of others, were extremely successful. JC Lenneydecer, iconic poster illustrator during WWII, used powerful, quotidian images such as the Boy Scout to evoke feelings of patriotism and good (ER1). The images portrayed in these pieces of public art were stimulating, convincing, and terrifyingly real. Likewise, the image of the American icon 'Uncle Sam' grew to represent something much greater than art. Although the government did not formally assimilate the image of Uncle Same until the 1950s, it had already become a pivotal part of the average citizen's conception of the government (Ketchum vii). The personifcation of this figure helped to make him that much more 'real', a presence to which one must respond as if one were responding to one's uncle. Conversely, art provokes understanding of our own surroundings; art assists us with defining our sense of place. The cultural icons with which we surround ourselves are largely artistic, and largely specific to our parts of the world. In the United States we are intimately familiar with a thousand small logos, each of them carefully designed to be both visually appealing and to fulfill a certain purpose. We see this art every day in something as commonplace as a the Greenpeace logo, showing the Tree of Life, or the Nike logo, a constant reminder for one to be all that he can be. We look

Post War Australian Art Essay Example | Topics and Well Written Essays - 1000 words

Post War Australian Art - Essay Example Imants  Tillers' greatest motivation is the production of pieces of artwork that show concerns regarding locality and place while also making evocations of the Australian landscape. Between 1974 and 1975, Imants produced Conversations with the bride. The piece of art typifies the installation media category. The installation provides a notable dialogue between Imants’ painting and Marcel Duchamp’s well-known painting entitled The bride stripped bare by her bachelors, even. Duchamp’s painting is also referred to as The large glass. Imants’ Conversations with the bride is a compilation of at least 112 miniature photographs and paintings (Hart & Tillers 2006, p. 9). These photos and paintings are set on multiple aluminum tripods with every image in the compilation being appropriated from The large glass by Duchamp.In addition, Conversations with the bride also appropriates images of Hans Heysen’s watercolor Summer of 1909, which had a characteristic Australian landscape, consisting particularly of gum and eucalyptus trees. This calls to mind the magnificent forces of nature that is similar to the 19th century Romantic landscapes. The large glass and Summer were painted approximately the same time, and as a consequence, Imants perceives them as equally representative of Australian cultural values (Stephen 2003, p. 16). These art pieces were sympathetic to Imants’ views at the time, especially with regard to Imants’ feelings regarding the element of the fourth dimension, which is also evident in Duchamp’s artwork. Imants researches a lot of sources, collecting necessary documentation vital for the compilation of the images inherent in the Conversations with the bride compilation. Conversations with the bride represent the painter’s post-modern strategy, which encompasses approaches such as intertextuality. Here, Imants’ artistic work elucidates the link between the artwork, the viewer and the ar tist. This relationship is exemplified through the use of layering whereby contemporary and historical references from both literature and art are comingled.  

Touch Screens Research Paper Example | Topics and Well Written Essays - 1000 words

Touch Screens - Research Paper Example (Nicholas, 2005, 315) The foremost model of contemporary touch screen with a transparent surface was then invented during 1974 by Dr Sam Hurst with his co-workers. Then the launch of touch screens with the five wire resistive technology took place during 1977. This technology is still in use by several companies that are making touch screen devices. During 1994, its name was changed from Elographics to Elo Touch Systems by the company. (Shelly, 2009, 01) These days a large number of both virtual and non virtual applications are making use of Touch-screen technology. It is estimated that there will be a yearly 25% increase in its usage in upcoming years. The board for Resistive Touch Screen is covered by a conductive layer of metal and a resistive coating that causes an alteration in the electric current which is recorded in case of a touch event and then delivered to the controller for further proceeding. Resistive touch screen panels are usually more reasonably priced but propose only 75% transparency and the coating can be scratched if sharp objects are used on the screen. Such types of touch screen panels remain unaffected from external pollutants e.g. dirt or water. This type of screens employs ultrasonic waves which pass over the touch screen board. When the screen is touched by the user, a fraction of the wave is taken up by the panel. This variation in the ultrasonic waves records the place of the touch occurrence and delivers this information to the regulator for further processing. This type of touch screens are the most modern type of the touch screens, however, these screens can easily get harmed due to external elements. This type of touch screens are covered with a substance that reserves electrical charges. When the user touches this type of screen, a minute fraction of charge comes out at the position of contact. (Nicholas, 2005, 316) There are circuits, present at all the corner

Feminism and Kate Chopin's The Storm Essay Example | Topics and Well Written Essays - 1000 words

Feminism and Kate Chopin's The Storm - Essay Example Louis, Missouri, all of whom were women of determination and intellect. This probably pointed her towards the path of feminism. Chopin lived and wrote her impressive repertoire of short stories in the second half of the nineteenth century, when the still patriarchal society revolved around the firmly rooted tenet that the ultimate goal of a fulfilled woman’s life was to be the ideal wife and mother and to adhere to the glorified virtues of submission and sacrifice. The feminist movement was very much in its’ nascent stages and centered round the demand for equal rights for women in the legal, political and educational spheres. Even before these issues could be resolved, Chopin’s stories delved into the complex threads of a woman’s life, including love, marriage, sex, women’s alcoholism, motherhood and autonomy. She was â€Å"a pioneer in her own time, in her portrayal of women’s desires for independence and control of their own sexualityâ₠¬  (Emily Toth, cited in Kate Chopin, n.d.). The concept of freedom for women, let alone their freedom to explore their own sexuality, was far beyond the comprehension of that age. Chopin wrote ‘The Storm,’ in 1898 but, perhaps anticipating a ‘storm’ of protest and condemnation, the story was published only after her death. In this portrayal of a woman’s extramarital affair, beautifully orchestrated to match the cadences of the storm raging outside, Chopin boldly asserts a woman’s freedom to explore and delight in her own sexuality, to participate in the sexual act as an equal partner and to fearlessly adhere to the same standards of sexual morality as a man. ‘The Storm’ begins its’ depiction of its’ protagonist, Calixta, as a woman who conforms to the mother and wife stereotype of that period. Her life, confined within the four walls of her house, is apparently quite satisfactorily filled with domestic chores like sewing and the laundry. She

August Wilson’s Fences Essay August Wilson’s Fences The immigration of Africans to America as slaves has had a great effect to many things including literature. Despite their experiences in this foreign land, they brought with them a different culture that had not been experienced in the American society. The stories and experiences of African-Americans have seen authors write books and plays being staged with large audiences. This is due to the different but almost similar stories that these people have to tell regarding their journey to America and how difficult it was for them to fit in the society they found. Introduction In 1983, the American playwright August Wilson released a play titled Fences. The play has a setting of the 1950s and it explores the evolving African –American experience with race relations as one of the many themes depicted in this play. The play revolves around a 53-year-old man named Troy who is an African-America. He is struggling to provide for his family and although he is a baseball player his color is a barrier for him being able to join professional baseball thus receiving little money to support his family. This paper seeks to analyze the play and check on why it was given the title Fences (Wilson). Analysis of the play Fences by August Wilson As earlier stated, the play is about a man named Troy. The play shows how Troy is struggling to not only provide for his family but also to fit in a society in which people are judged by their skin color. The theme of race discrimination is portrayed well throughout the play. First, in the 1950s in which the play is set, people of color were seen as those who do not deserve any good thing in the society. They were associated to social crimes and ending up in jail for a crime not committed was a normal phenomenon (Wilson). However, emotional disconnect with the society they lived in and failure to secure a job so as to earn a living was greatly contributing to them ending up being involved in these social crimes. In the play, Troy is shown as a baseball player a game he had learnt and played while in prison. He had ended up in prison for an accidental murder he had committed during a robbery. From this act it is evident that due to his failure of securing a job, Troy had ended up involving himself in robbery so as to earn himself a living but this time it turned out ugly and he ended up in prison. Further, discrimination is seen at work place where some jobs could not be done by an African-American but instead they were reserved for the whites. This is seen when Troy manages to secure a job with a garbage collecting firm and he is heard asking Mr. Rand; who he refers to as the boss, why black men were not allowed to drive garbage trucks. This shows that indeed there was race discrimination at work place where African-Americans could not be bestowed with some responsibilities. The act of being denied an opportunity to drive a garbage truck can be seen as a sarcastic event. It can be viewed in the way that even if garbage collection was being seen as dirty work that could only be done by those who were seen as less fortunate in the society, the fact that driving a garbage truck was seen as â€Å"literary driving a vehicle†, an African-American would not be allowed to drive the truck since they were restricted to do so during that time (Tamura). In addition, the play shows Rose who is Troy’s wife with whom they have a son named Cory, however, Troy has a son Lyon from a previous marriage but he does not leave with him. Gabriel is Troy’s younger brother who has notable psychological damage after he suffered head injuries when he was serving as a soldier. This new development of Gabriela having served as a soldier brings contrast of sentiments of race discrimination and at the same time it can be viewed as one way in which discrimination of people of the color was being cemented. First as a contrast, this play shows how certain jobs were being reserved for whites. Soldiers were people who not only deserved respect from the society but also received a good pay. Therefore, Gabriel’s employment as a soldier, contrasts the theme of discrimination where some jobs such as a being a soldier were being reserved for those the society thought they owed respect to. However, it can be viewed differently in the sense that owing to the tasks, experiences and challenges that faced soldiers in the battle fields, African-American men were seen as the right people for the job. This follows, the understanding that most of those who served in the army died in war or if one was luck to survive they would come home having sustained severe injuries like in the case of Gabriel. This can be seen as a form of discrimination where those who were less regarded in the society were being recruited as soldiers since the society would be seen not to worry even if it lost them (Tamura). The play unfolds on a payday when Troy and his friend Bono are drinking and chatting. His son Lyon comes to him asking to be lent 10 dollars promising to refund the money soon since his girlfriend had secured a job. Troy gives him a hard time but after persuasion from his wife Rose, he finally lends his son the money. From this scenario, one can see that the family is really struggling to survive owing to Lyon’s inability to raise even 10 dollars thus leading him to borrowing from his father. This shows that African-Americans were struggling a lot so as to survive in a society where living standards were high and a society where job opportunities were rare given the much rooted racial discrimination (Wilson). Further, as the play continues, Cory tells his parents of an opportunity for a college football scholarship. Troy vehemently condemns his son’s thought of applying it and they argue. Troy does not want his son to play basket ball since he does not him to experience the racial discrimination he went through during the time he was playing baseball. The man does not back down his argument and following his experience with racial discrimination he is not ready to watch his son go through the same. As a result, Troy even approaches Cory’s coach and tells him that his son will no longer be playing football. Upon discovery of his father’s lies, Cory confronts him and they end up in a fight that causes Cory to be thrown out of the house by his father. This scenario shows the effect that racial discrimination had to Troy’s life. Following him denying his son the opportunity to play college football with an excuse of racial discrimination, one can see that indeed Troy had gone through tough time due to racial discrimination and he was protecting his son. Despite his time of playing baseball and that of his son playing football being different, Troy could hardly believe that racial discrimination could have melted away, thus, the unmoved stand exhibited by him(Wiggins Miller). Consequently, after Cory is kicked out of the house, they no longer get along with his dad. This can be seen during the final act when Troy dies and Cory refuses to attend the funeral due to the long-standing resentment. However, after his mother’s persuasion, Cory attends the funeral to pay respect to the man who had tirelessly struggled to provide for them even if he was hard headed. The rivalry between son and father can be traced back to have been caused by racial discrimination. This is due to the fact that if Troy had not suffered through discrimination, he could not have denied his son to take the college football scholarship and as a result they could not have argued to the extent of later not setting eyes on one another. One can see the indirect effect that racial discrimination had to people’s lives (Wiggins Miller). Further, during Troy’s burial, Cory had just come from the military training. This can be analyzed as a positive step towards fighting racial discrimination. This follows the fact that during his father’s youth days, certain jobs opportunities such as joining the military were mostly given to the whites. Therefore seeing Cory coming out of the military training it is evident that with time, racial discrimination had come to reduce thus allowing African-Americans be able to get job opportunities which earlier being people of color they could not easily get. In addition, throughout the play, Troy is shown as a man who had a different cultural influence or different socialization. First, this can be seen through his son Lyon who was from an earlier marriage. Further, in the play, Rose discovers that his husband has been having an affair with a lady called Alberta and he had made her pregnant. However, Alberta dies during childbirth and Rose accepts to adopt her daughter Raynell whose father Troy dies when she is seven years old. Being an African-American, the act of having more than one wife is not out of the norms owing to African culture with him. However, finding himself in a society where polygamy is viewed as a thing past by time, Troy could not marry Rose while still having the first wife and he could not bring Alberta as another wife thus he ended up having an affair with her other than coming to the light (Sofola).. In the African culture, to which Troy can still find some association, most communities allow polygamous marriages as this is seen as wealth as the man will have many children from these wives. Traditionally, in the African culture having more than one wife was seen as a public sign that a man had more resources that would allow him to marry as many women as he pleased. However, the culture was against adultery and a man would not be allowed to bear children outside marriage unless he would later end up marrying the lady (Sofola).. Therefore, although the African culture among the African-Americans was fading away, its influence continued to affect them for years. Consequently, Troy was a man who had been influenced by this culture but the society which he currently lived in was not in support of the culture. Therefore, this explains his act in life of having a first marriage, then marrying Rose and finally having an affair with Alberta. Troy’s case shows the effect that migration to the West had to African-Americans; it did not only give them a hard time trying to fit in a society where they were less regarded but it also eroded their cultures and presented them with a different and difficult socialization (Sofola). Having analyzed the play, one would seek to answer the question on why it was given the title â€Å"Fences†. First, the theme of racial discrimination can be seen to have portrayed the title Fences. This is seen throughout the play where lines of racial discrimination were used to deny Troy and other African-Americans job opportunities. This judgment on bases of color is a fence in itself since it prevented them from getting good money to support their families. In addition, Troy could not join professional baseball playing due to the ‘fence’ of racial discrimination. However, to Cory, his father is the fence that does not allow him to get the college football scholarship after he refused him on the grounds of racial discrimination. In addition and to the literal meaning, Rose wanted to build a fence and forced Troy to start so that she could protect what is hers in the inside and leave what belongs to the society outside the fence. Conclusion Throughout the play, racial discrimination is shown as the cause of anything that Troy’s family is going through. One can appreciate the writer’s overemphasize on this issue owing to the fact that this play is set in the 1950’s when racial discrimination was still evidently being experienced. The play assists one to understand the effect that racial discrimination had on the lives of African-Americans as well as the influence of Western culture to their socialization and culture. This play will assist in keeping the history of the experience of African-Americans in the American society and it will remain to be a crucial part of literature.

Isolation of β-Amyrin from Plant Parts of M. barteri

Isolation of ÃŽ ²-Amyrin from Plant Parts of M. barteri ISOLATION AND BIOLOGICAL ACTIVITY OF THE TRITERPENE Î’-AMYRIN FROM THE AERIAL PLANT PARTS OF MAESOBOTRYABARTERI(BAILL). Abstract Maesobotrya  barteri(Baill), belonging to the family EUPHORBIACEAE, is a medicinal plant growing widely in tropical Africa. The Aerial plant parts of Maesobotrya barteri (Bail) were collected fresh from Orokam, Ogbadibo local Government of Benue State, Nigeria in July, 2013. Taxonomical identification was done by Mallam Musa Abdullahi at the Herbarium unit of Biological sciences Department, ABU, Zaria, Nigeria. Pulverized aerial parts of Maesobotrya  barteri (960g) was exhaustively extracted successively using petroleum ether, chloroform, ethylacetate and methanol and concentrated in the rotary evaporator at 40oC. The ethylacetate fraction having the highest activity against test microbes from preliminary crude microbial screenings was subjected to phytochemical studies, antimicrobial analysis and column chromatography (CC). The column chromatography yielded fraction EN, which was further purified using preparative thin layer chromatography to give EN1. The structure of the isola ted compound was established using 1-D NMR and 2-D NMR spectroscopic analysis and by direct comparism with data reported in literature was confirmed to be ÃŽ ²-amyrin. The bioactivity of this compound was carried out using some clinical pathogens and the activity compared with standard drugs and this was found to be comparable with the standard drug. Keywords: Maesobotrya  barteri; Medicinal plant; bioactivity; Ethylacetate extract; ÃŽ ²-amyrin Introduction Maesobotrya sp is a variety of flowering plant belonging to the family Phyllanthaceae, or by some authors classified in Euphorbiaceae. The Euphorbiaceae plants are shrubs, trees, herbs or rarely lianas [1]. Plants of the Euphorbiaceae are known to be rich in terpenoids (69.5%) [2]. In Nigeria, the species M.barteri is under-exploited although the tree is of both medicinal and nutritional importance [3]. Maesobotrya species are used medicinally in different regions in Africa [4]. It bears succulent black-purple fruits that are edible and stain the tongue. The nutritive values of the fruits and seeds have been studied in Southern Nigeria [5]. Thus, this study aims at validating the antimicrobial effects of the aerial plant parts of Maesobotrya barteri used in traditional medicine in Orokam town of Benue State,Nigeria, as well as potent compounds that can be used as precursors for synthetic drugs. The presence of secondary metabolites in plants generally has been confirmed by [6], [7] and [8] through useful procedures and suggestions to get to targeted precursors which are of useful aids in the formulation of modern drugs. Plant Material The aerial parts of Maesobotrya barteri were collected from Orokam in Ogbadibo local government area of Benue State in the month of July, 2013. They were properly identified at the herbarium, Department of Biological Sciences, Ahmadu Bello University, Zaria. The whole plant was sorted, air dried under shade, segregated and pulverized by mechanically pounding them using wooden mortar and pestle. The pulverized plant material was stored away from moisture. Extraction 980.54g of the pulverized plant materials were carefully weighed and loaded into a Soxhlet extractor. It was extracted successively with Petroleum ether (60-80oC), Chloroform, Ethyl acetate (76-78oC) and Methanol by hot continuous percolation method in the Soxhlet apparatus for 72 hours respectively. Solvents used were those of JHD and general purpose reagents The extracts were concentrated in vacuo at 40oC using rotary evaporator and subjected to air drying to give dried crude extracts. Isolation The ethyl acetate extract was the most sensitive extract from the antimicrobial screening and was subjected to column chromatography (CC) for fractionation. Solvents used to run the column chromatograghy were sealed and are products JHD with 98% purity. Fifteen grams (15g) of the extract was dissolved in ethyl acetate and preadsorbed on 10.0g silica gel (qualikens 60-120 mesh). The dried pre-adsorbed extract was transferred to a mortar and ground to give a fine powder and was added at the uniform layer on top of the column. The petroleum ether descended on a horizontal line indicating that the column was well packed. A total of 105 fractions (50mls) each were initially collected using gradient elution with a solvent combination of petroleum ether and ethyl acetate, starting with 100% petroleum ether with an increasing polarity of 1% ethyl acetate. Similar fractions were pulled together based on monitoring from TLC. Fractions F20-F25 were pulled together at the ration of 8:2 and where subjected to further purification using Preparative thin layer chromatography to obtain a solid white amorphous substance which after several trails using different solvent combinations showed a single spot which was visible under the UV lamp and after spraying the TLC plate with 10% H2SO4 and oven dried for 5minutes at 60oC. The solid white amorphous substance produced was insoluble in ethyl acetate or petroleum ether but soluble in chloroform. Results and Discussion From the preliminary antimicrobial screening of the crude aerial plant parts extracts of M. barteri, ethylacetate extract exhibited the highest activity against the test microbes used via their zones of inhibition. Therefore, an activity guided isolation was undertaken. Bioactivity of Compound EN1 Pure Isolate The antimicrobial activities of compound EN1 isolated from ethylacetate extract of the aerial plant parts of M. barteri was examined and agar disc diffusion method [13] was employed for the determination of the antimicrobial activities. The pure compound was determined using some pathogenic microbes; the microbes were obtained from the department of Medical Microbiology Ahmadu Bello University Teaching- Hospital, Zaria, Nigeria. The determination of minimum inhibitory concentration was carried out using the nutrient broth susceptibility assay prepared according to the manufacturer’s instructions, as recommended by NCCLS [14]. Minimum inhibition McFarland turbidity standard scale number 0.5 was prepared to give turbid solution. Normal saline was prepared and was dispensed into test tube and the test microorganism was then inoculated into the normal saline, incubation was at 37oC for 6hrs, dilution of the microorganism in the normal was performed until the turbidity marched that of the McFarland by visual comparison at this point the microorganism had a concentration of about 1.5à Ã‚ ¥108 cfu/ml. Minimum Bactericidal and fungicidal concentration of compound EN1 was carried out to check whether the test microbes were killed or only their growth was inhibited. Mueller Hunton agars were prepared according to the manufacturer’s instruction, as recommended by NCCLS [14]. They were boiled to dissolve and were sterilized at 121oC for 15 minutes, the media were cool to 45oC and the medium (20ml) was poured in to sterile Petri dishes, the plates were covered and allowed to cool and solidify. The contents of the MIC in the serial dilution was inoculated on to the media, the media were incubated at 37oC for 24hrs for the bacteria and at 30oC for 1-7 days for fungi, after which the plate were observed for colonies growth. The MBC/MFC was the plate with lowest concentrations of the extract without colony growth. Table 2 shows the Zones of inhibition (mm) of the pure the compound EN1 from the ethyl acetate fraction which showed remarkable activity against twelve of the sixteen organisms tested. Compound EN1 could not inhibit the growth of Corynebacterium ulcerans, Candida albicans, Candida tropicalis, Aspergillus fumigates, Aspergillus nigre. The various minimum inhibitory concentration (MIC) and minimum Bacteriocidal concentration and fungicidal concentration (MBC/MFC) for the different microbes are as shown in Tables and the bioactivity of the aerial plant parts of M. barteri is comparable to the drugs Ciprofloxacin, Fluconazole and Fulcin used as positive controls.

Antimicrobial screening reported from other natural products has also confirmed the microbial properties of ÃŽ ²-Amyrin. ÃŽ ²-Amyrin was isolated from Ardisia elliptica [9], a medicinal plant used for alleviating chest pain, fever, liver poisoning and parturition complications. It was found that ÃŽ ²-Amyrin was six times as active as aspirin in inhibiting platelets aggregation. ÃŽ ²-amyrin was isolated for the first time fromLaurencia microcladia, marine algaedistributed widely in Egypt found to have antibacterial activity against Staphylococcus aureus, Bacillus subtilis, Salmonella typhi, Escherichia coli, and Pseudomonas aeurginosa [10].

The 13C NMR spectrum (Figure 3) showed thirty (30) major recognizable carbon signals, eight methyl groups at ÃŽ ´37.0200 (C-22), 28.0359 (C-23), 15.5986 (C-24), 15.4777 (C-25), 16.9846 (C-26), 24.2027 (C-27), 17.0954 (C-28), 28.1492 (C-29), 23.3098 (C-30) and a secondary hydroxyl bearing carbon 79.0731 at (C-3). It also showed some recognizable signals at ÃŽ ´ 125.9002 and 137.9624 ppm which is assignable to the double bond at C-12 and C-13. In addition, ten methylene groups, eight methyl groups , six quaternary carbons atoms from DEPT experiment were observed. The chemical shift at ÃŽ ´137.962, 125.9002 which are C-12 and C-13 and the consistent flow of methyl groups from C-23 to C-30 were characteristic peaks for a ÃŽ ²- Amyrin type of skeleton [11] and [12]. 1HNMR, 13C NMR and DEPTH spectra of the proposed compound ÃŽ ²-amyrin Figure1: 1HNMR Figure 2 : 13C NMR Figure 3: DEPT Table 4: Comparison of 13C NMR spectrum data of ÃŽ ²-amyrin Obtained from the Aerial parts of M. barteri with literature Carbon Position ÃŽ ´13CNM ÃŽ ´ppm ÃŽ ²-amyrin, Experimental ÃŽ ´13CNMR ÃŽ ´ppm ÃŽ ²-amyrin, Literature [12] ÃŽ ´13CNMR ÃŽ ´ppm ÃŽ ²-amyrin, Literature [11] 1 38.8495 38.7 37.3 2 27.2530 27.2 28.28 3 79.0731 79.3 71.85 4 38.7715 38.5 37.30 5 55.2568 55.1 36.81 6 18.3150 18.6 21.12 7 38.6441 32.4 42.35 8 39.5194 39.8 45.90 9 47.9239 47.6 50.18 10 36.7105 36.9 36.55 11 23.5770 23.6 24.33 12 125.9002 121.7 121.70 13 137.9624 145.2 140.81 14 42.0388 41.7 44.36 15 29.3557 26.2 26.13 16 21.1608 26.1 23.11 17 29.6969 32.6 48.48 18 47.5759 47.2 45.89 19 39.0811 46.8 39.82 20 30.6267 31.0 36.49 21 33.0001 34.7 34.00 22 37.0200 37.1 31.71 23 28.0359 28.0 29.3 24 15.5986 15.4 19.84 25 15.4777 15.4 19.10 26 16.9846 16.8 18.90 27 24.2027 25. 9 18.30 28 17.0954 28.4 19.20 29 28.1492 33.8 36.18 30 23.3098 23.7 19.42 Proposed structure EN1-(C30H50O, 426.7 g/mol) Name: ÃŽ ²-Amyrin or ÃŽ ²-Amyrenol Conclusion The isolation of ÃŽ ²-Amyrin from the aerial plant parts of M. barteri, whose bioactivity was established from this work by its zone of inhibition, is comparable to the drugs of Ciprofloxacin, Fluconazole and Fulcin. This justifies why the plant really serves as a general purpose antibiotic in traditional medicine in our society. The preliminary phytochemical screening also shows that the ethylacetate extract contains other classes of compounds that can be further isolated and tested for microbial activities and this can lead to chains of discoveries as the quest of precursors for modern drugs are continually on course.

Analysis of Human Resource Models

Analysis of Human Resource Models Analyze and evaluate the characteristics of any three of the following human resource models and list the related features in each of the models. – Contingency model, Best practice model, Harvard Framework, D Guest, M Patterson. (5 marks per model = 15 marks total) Contingency Planning Contingency theory takes societal and settings alteration in individuals and their commercial undertakings as its obvious worth and assumes its standards keeping in its understanding. There are twofold important repercussions to this kind of theory: if there is no single finest way, then even seemingly fairly alike companies, for instance, two close schools, may select considerably different edifices and still endure, and be rationally successful in attaining their tasks, and so on if unlike portions of the similar company are predisposed in different methods by the eventualities residing upon them, then it may be suitable for them to be organized differently, Best Practice Model The best-practice Model supports a universalistic viewpoint – all companies will understand performance progress if they accept it. There are three key essence of best-practice concepts that should be should be stated. First of all, the models improve staff capability and information through decent staffing and teaching. The second point is inspiring desired conduct through durable enticements. Lastly, encouraging concepts and influence from interested and improved employees. The benefits of this kind of model can be seen on its simple best practice. Next is the acknowledgment of â€Å"corrupt† practice. The third benefit is creating guidelines of thumb for choices; training; evaluation approaches. Lastly is that there is no requirement to invest again. Harvard Framework This is the modest and practical way of plotting the labor and resources of men and females in an organization and stressing the major alterations. Gathering and examining facts at the organization and in the area. Gathering baseline information. As a preparation and application of tool for plans and programmes At the problem searching phase of planning, earlier an intervention is planned. To measure the effects a programme may have Identify and describe at least twelve human resource management activities that would be conducted within the ‘simulated’ organization. Induction Management Induction Management aids staffs to experience every stage of atmosphere of organization and a starter to his group and others. It provides them the policy of recognizing and understanding the values and identifying â€Å"Who is who†. It is such a stage which stretches a hint of whole Organization in that little duration. Training Management Training Management denotes to the practice of rendering exercise, workshops, training, mentoring, or other learning occasions to staffs to motivate, contest, and inspire them to achieve the roles of their position to the finest of their skill and within criteria established by state, Compensation and benefits Compensation comprises not only income, but also the internal and external compensations and benefits the staff is given with in return for their input to the company. To decide compensation, companies should make a benefit and rewards project. This type of project summarizes a reasonable procedure for paying staffs. A fine-structured project with a good stability of wages, paybacks and rewards will aid a company to stay and sustain competitive in labor market. Performance Management Performance management is the procedure of generating a work atmosphere or setting in which individuals are permitted to achieve to the finest of their abilities. Attendance Management It is the  means for following and collecting data about how much period a staff  spends on the work setting. Recruitment Management Recruitment is the process of searching and enticing skilled candidates for employment. The procedure starts when new staffs are required and finishes when their applications are passed. The outcome is a pool of submissions from which new workforces are nominated Benefits Management Benefit management comprises generating and executing benefit policies for existing staffs or presenting new policies to job applicants.

Fate of the Passionate in Virgils Aeneid Essay -- Literature

Virgil’s The Aeneid, to this day, remains one of the most influential epics to ever grace the merciless limitations of manuscript, inspiring, in pop culture as well as literature, an onslaught of themes, mythology, values, and the general sense of what a hero must be-or do- in order to overcome the obstacles of the gods and man. Written somewhere between 29 and 19 BC, consisting of twelve books (although never completely finished), The Aeneid takes us through the turbulent journeys and prophesied triumphs of Aeneas, a warrior and man bound by piety and destiny. Like usual, in every great epic, there are many battles: heads gashed open and gore galore; however, to say that this master piece is just for men would be atrocious, considering that Venus, Aeneas’s mother (the goddess of hunt, extremely beautiful), plays a major role in the book from beginning to end, but, although women are portrayed as a symbol of strength (most of the time, at least), one cannot ignore the invocation to the muse at the very beginning: â€Å"I sing of arms and of the man† (3). Through the wars, travels, monsters, and grief that awaits our protagonist, I feel that the relationship between Aeneas and Dido, the queen of Carthage, holds special relevance in my life, for I have loved and lost as well, but one thing may surprise you, I have seen it through the eyes of Dido, not Aeneas. Fortunately, for me, I didn’t have to sacrifice myself, but I did learn to love, relish it, and then, sadly, let it go. Early in the beginning of the poem we see Aeneas, surrounded by blood thirsty Greeks, trying to save his family-fighting as well-and, after an apparition of Hector pleas with him to leave, eve... ...er allowing his life to interfere with his destiny, if indeed he truly believed in it, for judging by his master piece, I must simply believe that he, in all of his expert wisdom on battle and virtue, failed to understand the complications of love and passion. As a man who has lost much, constantly pondering the ambiguity of love, I cannot deny that the road to happiness is a long, uncertain path, but, just like my loss of companionship, I can’t help but to think what would have happened if Aeneas would have just forsaken his path and cradled Dido until the grave, yet one cannot deny the fate of passion, in all of its uncertainties and unseen truths.

Caught in the Net (the Internet, that is) :: Personal Narrative, essay about myself

"Hello. My name is Kim. I'm an online-aholic." There. I've said it. I guess I've been addicted for quite some time now, but I have just begun to realize it. My first interaction with the "Net" began when I was only 15 years old. My dad was the computer coordinator at our school, so he wanted to try Internet access at home before installing it at school. We became America Online members in 1993. None of my friends had e-mail back then. My relationship with e-mail started like a Romeo/Juliet conspiracy. I experimented with the Net on the sly at night when the rest of my family was sleeping. That's when I first created my own screen name. Although I was too young to drive, the locked doors of adolescence were suddenly flung open before me. I could be social in the evening rather than hang out with my family-the typical family that every adolescent wants to escape from. Hanging out in chat rooms became a nightly ritual. I quickly found friends who would meet me there, give advice for my adolescent problems, and discuss things such as dating, theater, religion, morals, and entertainment. I began to form emotional attachments with these new friends. In fact, I maintained two online relationships for over two years. Raul is a Hispanic teenager living in one of the roughest cities in our nation, Compton, California-the filming location of the 1991 movie Boyz 'N the Hood. I met Raul in a chat room one night. He sent me an instant message in the middle of a discussion about religion and asked what I believed. My subsequent chats with Raul seemed to have an impact on him and helped me to grow in my own faith. I occasionally took Raul's questions to my preacher or Bible teacher when I needed further explanation. For Raul's 18th birthday, I sent him a Bible that I bought with my paper-route earnings. Raul and I wrote each other for two years, and then Raul had to sell his computer. I haven't heard from him since. Brian is a middle-aged high-school theater teacher in Bowie, Maryland. He answered one of my message board posts about an upcoming audition for our school's performance of The Sound of Music. I was 17 years old at the time and greatly desired a part in the musical. Brian had expert advice for how to nail the audition, and as a result I was cast in the role of Maria. Caught in the Net (the Internet, that is) :: Personal Narrative, essay about myself "Hello.

Simon And Ralph Comparison At Chapter 3 :: essays research papers

Golding portrays the different characters and those ideologies that accompany them with a strong contrast in writing style. To further understand this we must compare characters from his Nobel Prize winning novel, The Lord of the Flies. A good example of this is Jack who represents evil, described at the beginning of chapter three, and Simon who represents good and spirituality, described at the end of chapter three.Golding writes the story with the knowledge that characters who strongly dominate the plot at any given time of the book will become associated with the mood and imagery of their surroundings. When he writes about Jack he creates dark images, to represent evil. One of the ways that he does this is by placing Jack in a dark and unpleasant jungle. The jungle that Golding describes is also humid, and makes the reader feel uncomfortable. He also describes Jack as being similar to animals; "†¦Then dog-like on all fours†¦", "†¦flared nostrils", as to create an image of a character who is governed by instinct and savagery. The mention of dark sunburn and freckles splashes the image of red colour on Jack's character signifying rage and lack of control. Every move that Jack makes is described as quick and deceiving, and this prevents the reader from trusting or admiring Jack.When Golding writes about Simon's sunburn, he describes it as a deep tan, which does not have the same connotation as Jack's red sunburn. Every move that Simon makes is slow and delicate; "†¦He picked his way up the scar†¦", "†¦He walked with an accustomed tread†¦". Simon is found in a beautiful scene with fruit trees, flowers, and honey bees. Butterflies dance, expressing the good spirit always accompanying Simon. Golding has the little ones who are the helpless and weak members of society seek Simon for aide in reaching fruit that they themselves cannot reach. This is done intentionally to show Simon's compassion, and Golding would not place Jack in a similar scenario.

Analysis of Hamlet Act II.2 Essay

Act 2, Scene 2 is an important scene for the audience’s impressions of Hamlet, as it is the first time we can see the â€Å"antic disposition† of which he has previously spoken. He enters the scene on page 50, and immediately enters into conversation with Polonius. We can see that the act of his madness relies upon rhetoric devices such as puns and double meanings, which are deliberately intended to confuse. On page 51, for example, when Polonius asks him what matter he reads, he replies: HAMLET: Between who? In this, Hamlet is playing on the double meaning of the word â€Å"matter†- although Polonius intends it to mean his reading matter, Hamlet knows it could also mean personal matters, and picks the wrong interpretation, intending Polonius to think that his mental instability is such that he cannot follow the conversation. Although there are these occasions upon which Hamlet seems to be truly mad, the audience can see that he is being rather clever in constructing his act. When Polonius clarifies the meaning of the word â€Å"matter† which he intended, Hamlet responds with a thinly veiled attack on him: HAMLET: The satirical rogue says here that old men have grey beards, (†¦ ) and that they have a plentiful lack of wit. Here, Hamlet pretends to discuss the â€Å"slanders† of which he reads, but the audience can see that he is commenting on Polonius as an old man. By mentioning the â€Å"plentiful lack of wit†, he recognises how obvious Polonius’ motives are in conversing with him, and attacking his methods. Although Polonius does not pick up on this, he does see that there is more to the â€Å"madness† of Hamlet than is seen, commenting â€Å"there is method in’t. † While Hamlet’s act here seems rather convincing, as soon as Rosencrantz and Guildenstern enter his madness begins to slip. His conversation with the two is coherent, as he directly questions them to see how honest they are. For example, on pages 53-54: HAMLET:Were you not sent for? Is it your own inclining? Is it a free visitation? This short, direct questioning shows his cynicism of the two- he knows that they did not come of their own free will, and is simply testing them to prove their honesty. When they are hesitant to answer, he decides they have not passed his test, and afterwards treats them with a contempt or disregard. This wariness in his personality will become important later in the scene when he contrives a means of testing Claudius. Furthermore, the coherency with which he asks these questions show the sanity underlying his act of madness. Hamlet himself recognises this, when on page 57 he comments â€Å"I am but mad north-north-west. â€Å", implying that although there are times when he acts with seeming insanity, he is also capable of coherent conversation. This also emphasises to the audience that what they see is simply an act, and underneath the madness there is a young man obsessed with avenging the death of his father. Although his mood during this first part of the conversation is that of anger and mistrust towards his two friends, there is an abrupt change in his speech and actions when the players are mentioned to him. In fact, his speech becomes uplifted and he appears to be genuinely excited about the upcoming play. For example, on page 55: HAMLET: He that plays the king shall be welcome- his majesty shall have tribute of me. This is rather ironic- while he shall welcome the actor who plays the king, in reality it is a king who is the source of all his problems. This shows Hamlet’s love for actors in that while very few people in his life are trustworthy and it is hard to distinguish their actions from the meanings behind them, one can be certain that the actors will be acting. After this, he then goes on to list the many characters who appear in a play, explaining what they shall do and how he shall enjoy it- â€Å"the lover shall not sigh gratis†. This also shows that he is knowledgable on the matter of the theatre, as he is acquainted with the many parts which are played. It also shows his excitement, as he speaks more a long time on the matter. His speech is not organised into short, direct questioning as before, but instead he speaks in longer, freer sentences. This change in syntax clearly shows his mood- whereas before his short sentences showed doubt and mistrustfulness, these longer sentences show that he is what he is saying is exactly what he thinks- in contrast to the earlier part of the conversation, he now clearly seems to be relishing and enjoying the words as he says them. This is the first time that the audience is made aware of Hamlet’s love of drama, which is an important part of his personality and will become vital later on in the scene, when the audience is made aware of his plans. It also explains how, when faced with the dilemma of how he should react to the news of the ghost, his immediate reaction is to put on an act. At the end of the scene, Hamlet is left alone and speaks his second soliloquy of the play. As is typical of Shakespearean dramas, soliloquies are used to give the audience an insight into the character’s innermost thoughts and feelings without worrying about the opinions and reactions of other characters towards them. The speech is organised into three main parts: the first, a comment on the player he has just seen perform, followed by a self-critical analysis, before he goes on to explain his plan of action. He begins by speaking about the player, who has put such great emotion into his performances that he weeps during them. Hamlet contrasts this with the state of emotional turmoil in which he resides, although he is not allowed to show it externally. During the soloiloquy, Shakepeare uses several rhetoric devices to communicate this distress to the audience- for example, the frequent use of exclamation marks, which suggest a passion behind his speech. By line 568, he uses a great deal of rhetorical questions: HAMLET: Am I a coward? Who calls me villain? Breaks my pate across? These questions serve to increase his anger, and as he says them his speech becomes increasingly passionate. At this point, he is talking about himself- by saying â€Å"Who calls me villain? † he is opening up to criticism from others, but then swiftly moves on to speak about himself. HAMLET: But I am pigeon-livered and lack gall During this section of the soliloquy, Hamlet reveals his attitude to the revenge which he has sworn to take. He shows the audience his conflicting feelings- on one hand, we can see that he feels he is cowardly for not having acted sooner. This shows a contrast between what he feels he should be and what he actually is, which is further reinforced when he explains â€Å"ere this/I should ha’ fatted all the region kites/ With this slave’s offal. † This shows that he feels that he should have taken revenge by now in order to remain true to his dead father, and yet he is reluctant to act too quickly. To add to this feeling, he has just ben watching the players speak of Pyrrhus, who was a man of revenge and action- what Hamlet feels he should be. He is also clearly filled with loathing towards his uncle- at one point referring to him as: HAMLET: Remorseless, treacherous, lecherous, kindless villain! This list of negative adjectives very clearly show the audience how passionate he is upon this issue. By this point, his extreme hatred of Claudius is obvious, and by describing him in this way Hamlet is only working himself into greater fits of passion and determination to act upon the situation. However, Hamlet is not, like his father, a man of war and fighting, but instead rather more cunning in his revenge- in this respect, he could almost be described as like Claudius. He realises that passion is not the way to solve his problems, saying on page 63: HAMLET: About, my brains. This signifies a change in his thoughts- whereas before he was speaking with passion and anger, he has now regained some control over his emotions and can speak with a greater coherency. It shows his belief that, in order to exact his vengance most effectively, he will need to remain calm and collected while thinking about it. As revenge is clearly the most urgent matter on his mind at this tiime, then, there is a need for him to think carefully, and by saying â€Å"About, my brains. † he is recognising this. It is at this point in the scene that the cynical facet of Hamlet’s personality comes back into importance- we can see that he needs evidence before he acts, as he declares towards the end of page 63: HAMLET: I’ll have grounds more relative than this. To the audience, this is further reinforcement of his suspicious nature- rather than simply take revenge without thought, he must first devise a plan to test the truth of the ghost’s words. This in in keeping with what we have been told of his past- namely, that he is a scholar from Wittenberg, which at the time was one of the most prestigious universities in Europe. Therefore, his questioning nature is in keeping with this- for, being educated, he is less likely simply to accept what others tell him wthout proof. We see this during his â€Å"testing† of the motives of Rosencrantz and Guildenstern earlier on in the scene, but only now does it begin to relate directly to the central plot. This concludes Act 2:2, during which Hamlet as a character has greatly developed. We see his plans begin to come together, as he feigns the â€Å"antic disposition† which was spoken of in previous scenes. The audience also begins to see his character develop, as we are introduced to such elements of his personality as his love for drama and his cynicism, all of which fashion the style which revenge will take, and ultimately guide the play to its inevitable ending.

The years

The geezerhood of 1901-1912 were a time of fast moving evolution for the united States on the tip of world relationships. As Roosevelt entered site, the enormous sit was placed firmly in his hands. He took control of affairs and adhesive frictiond them in the counseling that he felt should be handled.

This won the reckon of the res publicas of the world. The spoilt junction at period was so overpowering that It far exceeded the countrys capableness. Roosevelt personality did non take Into consideration that at many ti mes In order to gradation the smear of potency he desire he had to dull the rest of the blade.

It awakened the country and made it feel pleasurable as it left a period of crime and corruption in politics. Most importantly, although it was still years away, it allowed us to start prepping for World War One, politically as well as militarily.When the handed-down Taft entered office after Roosevelt, he cognise that the he would have to show the nation he was non the same type of leader as Roosevelt was. He was not proficient enough of taking the enormo us risks Roosevelt had made common practice during his presidency. However, Taft was face with great tasks. He could not let the spic-and-spanly formed American pudding stone fall by the curb. He could not let the another(prenominal) countries of the world lightheaded respect for us and gain more land in far off places. So Taft developed a new form of global policy.Big Dollar circumspection as it was called was more of a tending driven policy than anything else. Instead of expanding the conglomerate with the Big Stick, Taft took benefit of American economic and industrial force. There could have been no better change flanked by the ultra policies of Roosevelt and the traditionalist ones of Wilson. The big dollar maintain American strength and influence, but did not expand It. This was shown by Tufts desire to kind a transcontinental railroad in China. Taft kept us on the point with world affairs UT, only at the conservative level that he knew we could handle safely.By ut ilizing the dollar he hit other nations where It hurts, the pocket. He made others Like those In South America loyal to us and paved our status In the world. Big Stick and Big Dollar diplomacy were both victorious polices In the respect that they skillfully validated what they were Intended to do. However, Big Dollar was more of a patch. It was accommodate as a do the to the lowest degree that we can type of policy. Therefore I believe that the Big Stick was far more victorious. If we did not have the timber of Dollar.
