Tracing Rules Essay Example | Topics and Well Written Essays - 2000 words

Tracing Rules - Essay Example It need not be a proprietary right. Often the tracing exercise begins with a bank account, which is a personal right against a bank.1 And sometimes, the repository of value with which the plaintiff begins is not a right at all, but is rather in the form of services. Services can enhance the value of assets, and in this way the value inherent in the services can be traced into the enhanced asset. It is sometimes said that a prerequisite to tracing in a court of equity is the establishment of a fiduciary relationship.2 If this were true, the consequences would be startling. A trustee sells trust land, and deposits the proceeds into a bank account into which he has earlier deposited some money of his own. A court of equity will allow the beneficiary to trace from the land, previously owned by the claimant in equity, into the balance in the bank account. It will also allow claimant to assert equitable proprietary rights in the bank account; that is a separate issue. On the other hand, a thief steals some money from claimant and pays it into a bank account into which thief has earlier deposited some money of his own. The tracing exercise would appear to be even simpler. But the thief does not owe fiduciary obligations to claimant. If it is true that a fiduciary relation is a prerequisite to tracing in a court of equity, then a court of equity is unable to trace into the bank account in the second situation. This seems absurd. What could possibly be the reason for such a requirement The standard explanation is that it is necessary to found the jurisdiction of equity: Agip ( Africa) Ltd v. Jackson. When a plaintiff wishes to conduct the exercise of tracing, he wishes to establish that the value inherent in his asset has been used to acquire another asset. That alone neither gives nor denies hearing jurisdiction to the Court of Chancery or its successor, a court exercising equitable jurisdiction. If the plaintiff is seeking specific performance or rectification, then t he Court of Chancery would have hearing jurisdiction, and it would allow him to try to prove the making of the contract. If he was merely seeking damages for breach of contract, then the Court of Chancery had no order jurisdiction to grant that remedy and so it would decline hearing jurisdiction.3 The exercise of proving the existence of the contract is neither peculiarly equitable nor peculiarly legal.4 The fact that a plaintiff wishes to trace is not determinative of whether the court has hearing jurisdiction. It is an exercise which is neither peculiarly equitable nor peculiarly legal. Moreover, it is neither peculiarly proprietary nor peculiarly personal; tracing is not a right but an exercise. But equitable rights, properly so called, are different in many ways from common law rights, and so the relief sought by the plaintiff is peculiarly equitable or peculiarly legal. Whether or not there is equitable jurisdiction to hear a claim is determined by the relief which is sought. I f the plaintiff asserts that she holds equitable proprietary rights in some new asset, then that is a claim which only a court of equity can evaluate; and that is the source of the court's hearing jurisdiction. But it makes no sense that a plaintiff should have to establish a fiduciary relationship merely to conduct the exercise of showing that her asset was used to acquire some other asset. When the Court of Appeal expressed its view that a fiduciary

Interconnectedness & Complexity Coursework Example | Topics and Well Written Essays - 250 words

Interconnectedness & Complexity - Coursework Example Woodrow Wilson (1887) meant that the consideration of politics and administration as separate elements they serve different roles. For instance, politics deals with the laws governing the planning of an area while administration is the execution and maintenance of the plans (Rosenbloom, 2015). Despite the two should be separated, they still interact with the urban planning practices because of the laws and administration. In reality, politics control urban planning to promote the interests of the parties and this should not be used in the administration of the urban centers. The concepts of interconnectedness and complexity compare with the theory posited by Woodrow claiming that the administration is separate from politics through the principles involved when executing the concepts (Rosenbloom, 2015). This implies that the two concepts are separate but must be incorporated to produce the desired outcomes. This is because of the usefulness of the separate variables used to determine the traffic flow and enhance time saving. Woodrow claims that the two should be separated to influence distinctiveness and inclusivity (Levy,

QUALITATIVE STUDY OF REASONS FOR NON- PARTICIPATION IN REGULAR Essay

QUALITATIVE STUDY OF REASONS FOR NON- PARTICIPATION IN REGULAR PHYSICAL RECREATION - Essay Example Therefore, it is vital to address this issue and comprehend the reasons why some women do not take part in leisureliness activities. The ‘qualitative’ study in this report deliberates the chief subjects or motives for non-partaking from women and likens these motives between matrimonial men and women. In the beginning this research, will provide a brief review of some previous research in this field mainly the reasons for not taking part in physical activity. In the second part, this research will provide a short description of the research method employed to collect data for quantitative research and lastly, it will illustrate and demonstrate the main reason for non-participation in physical recreation of married women and men. Literature Review There have been various studies concerning the subject of non-participation of married men and women in regular physical recreation. From various studies carried out earlier, a significant number of married men and women have li mited time to take part in regular physical activity because of various roles at hand. Time insufficiency according to research is the feeling that a person does not have adequate time to carry out all things that one would like to carry out. This has become one of the big complications that both men and women are encountering currently. Various researches have reported that time issues are the most regularly stated explanations or causes for not taking part in regular recreational activities (Thomsson, 2004). Lack of adequate time is also considered as the most limiting aspect to various individuals who desire to take part in a multiplicity of recreational activities, as well as for not using homegrown park and recreation services. Research shows that married women are at a greater disadvantage concerning time for regular recreation than men. This is because of various household responsibilities and family devotions compared to their male counterparts. Further studies have revealed that both working and unemployed married women have limited time for recreation activities than their husbands.it has been emphasized by research that limited time because of family responsibilities was noted by women as a primary barriers in early and later family stages. In addition, lack of enough finances also causes lack of participation in regular recreational activities. Research shows that low income limits access to the resources and abilities necessary to take part in a range of recreation activities. This is because finance is positively related to participation in various sorts of leisure activities, as well as use of public park and recreation resources. For instance, the development of outdoor recreation has also been ascribed to an increase in the gross national product and individual incomes. Family magnitudes have reduced over the years and the fraction of married partners with children in the populace has minimized. Concurrently, the portion of ‘single-paren t’ families has increased; however, single-parent families characteristically have lesser earnings, a lesser amount of movement, and a lesser amount of free time than do two-parent families do (Torkildsen, 2007). Thus, single-parent families are expected to profit from outdoor recreation chances that are near to their homes. In addition, coming from unprivileged homes or lack of sources because of proceeds means that some married couples cannot take part in recreational acti

Aspects of microeconomics and macroeconomics

Aspects of microeconomics and macroeconomics On this assignment will be looking into different aspect of microeconomics and macroeconomics, will be taken into consideration the definition and concept of the whole question as follow below. Part 1 (Micro section) Q1 To help understands by defining Demand that is the quantity of a good which consumers want, and are prepared and able to pay for. In this case the demand of organic food and drink has fallen sharply, and the main influence for fallen on demand for those products are: price; income; the price of substitute goods; the price of complements; taste; demographic factors; advertising and expectations. Price is one of the most important factors and it shift demand curve when it rises, the effect is shown by a movement along the demand curve, because consumers are likely to substitute cheaper alternative goods. http://upload.wikimedia.org/wikibooks/en/c/c1/DemandCurveMovementExample2.png The demand curve is downward-sloping, showing that as a price falls, demand rises, and vice versa. In this graphic, a reduction of price from P2 to P1 causes a rise in demand from Q2 to Q1. Usually, the more people earn, the more they will spend. The demand for most goods increase as income rises, and these goods are known as normal goods. And organic food and drink are normal goods, because the demand falls as consumers income falls, and vice versa. Demand can change sometimes, because of the expectation of price changes in the future. For example, post-Christmas sales may push customers to postpone spending until January. In an article entitled Food Price, Ellis makes the point that (à ¢Ã¢â€š ¬Ã‚ ¦) The proportion of shoppers buying organic food dropped by five per cent in the previous year. In July 2009, research carried out by marketing consultancy Cohn and Wolfe also reported that British shoppers are turning their backs on premium foods, organic produce and Fair-trade goods. According to the Cohn and Wolfe report, 69 per cent of shoppers say they intend to stick to their belt-tightening shopping practices even after the downturn ends (). www.bbc.co.uk/food/food_matters/foodprices.shtml#what_about_the_recession. Q2 The production possibility frontier illustrates the problems of scarcity and choice and the opportunity cost of resources allocation decisions. The opportunity cost of something is what you give up to get it. To understand the idea the economy, which produce two goods as manufacturing and financial services, with all resources employed, producing more financial services can only be achieved by some sacrifice on manufacturing services. It can be illustrated on diagram below shown. B A 0 The frontier shows all the maximum possible outputs given the economys existing quantity of resources. It can have any combination of goods along the line. Point A shows a society which is failing to use all of its resources to the full, either through inefficiency or unemployment. Point B is currently unachievable, but can be achieved throw economic growth. The shape of the curve is bowed outwards to the origin, is based on the notion of that society progressively allocates more resources to the production of a particular good, the opportunity cost of doing so will increase. In other words the curve is bold because the more input the less is the output. For example, UK economy is based on services because the government decide not to invest on manufacturing and thought the easiest way to make money is by providing financial services especially banks and shoppings only 13% of UK GDP comes from manufacturing. Now the services have been beaten by the recession, many banks are facing financial problems, because they use to lend money to people who were at lower income. Many of these people cannot repay their mortgage because they lost their jobs and they are haven their home been repossessed, it is causing serious problems on economy; records can be seen on graphic below. http://news.bbc.co.uk/1/hi/business/7789844.stm Q5 It is important to be aware of the differences between theoretical models: a perfectly competitive firm; monopolistic competitive; oligopoly and a monopoly. But here only two will be taking into account. Perfectly Competitive Monopoly Very many small suppliers One supplier only Homogeneous goods; Suppliers products are a perfect substitute for one another One type of product only; no close substitutes available One market price Price set by one firm. Possibly price discrimination Demand curve of individual firm is horizontal. Demand curve of firm and industry is downward-sloping Perfect information Imperfect Information No barrier to entry in the long run Barriers to entry Clearly the assumptions essential perfect competitive extremely are not likely to apply in the real world; there is no market which obeys all the conditions. On the other hand, there are some that come close. The stock markets and foreign exchange are examples. Also complying with regulations the market is costly, as is training and equipment needed to operate in such a sophisticated, highly computerised market. As you can see, the conditions are not obeyed perfectly, but it may be that the markets are near enough the formal definition that displays the main characteristics of a theoretical perfectly competitive firm. The monopolist produces less, and charges more, than the perfectly competitive firm. He makes supernatural profits, which would be competed away in a perfectly competitive market in the long run. He may also be technically inefficient, operating at above minimum average cost. The monopolist equates marginal cost and marginal revenue. The perfectly competitive market equates marginal cost and average revenue. In perfect competition, each firm produces at the point where P=MC. PART 2 (Macro section) Q1 The economy is in recession because production is below its potential capacity, the term recession mean lack of money supplier. To respond this crisis the government is intervene through fiscal and monetary policy to increase aggregate demand, and the way for doing it is by supporting bank balance sheet; cutting in direct taxation(VAT -2.5); quantitative easing (bank of England) and employment level. Fiscal policy is basically about government taxation and expenditure. To help in this crisis the government has reduce the consumption tax VAT -2.5 to 15% to stimulate investment expenditure, but there was a big criticism about this idea, because reducing VAT did not cause long term impact in the economy, would cause more impact if they invest the  £12 billion building an public infrastructure to increase an aggregate demand. Monetary policy the bank of England is an independent monetary policy institution there a committee people appointed by government to make decision about interest rate, monetary policy is focus in regulating the money supplier in the economy through interest rate it has a big impact on aggregate demand. The bank of England has reduced its interest rate to 0.5% to boost the UK economy and start lending money to business and individuals. As the economy beginning to grown some others part of the economy will be automatically adjust, for example an increase on employment. Some companys worker has agreed to have a pay cut on their salaries to reduce people being redundant (BA Line). Automatic adjust as the economy beginning to grow the employment rate will decline http://news.bbc.co.uk/1/hi/business/7832714.stm According to Kyosaki, Robert, Rich dad poor dad 2, E, (2008), few people have anticipated the financial problems we face today were created more than 60 years ago by politicians and lawmakers predecessors. Q3 In the post-war period government have adopted four central objectives of macroeconomic policy: low inflation; full employment; rising economic growth and balance of payments. But full employment is too hard to archive especially there is a trend for national income to experience cycle of growth and contraction, i.e. boom and recession. These cause severe social problems as failing level of economic activity throws people out of work and causes business to fail. The term unemployment means those of working age who are without work, but who are available for work at current wage rates. Unemployment could still exist because of many causes mentioned below: Cyclical unemployment, this occurs due to a deficiency of demand, often refers to the fact that in such circumstances it is possible that prices will fall. Frictional unemployment, refer those people who are unemployed and jobs available rarely match perfectly, leading to an inevitable degree of unemployment. Technological unemployment, can occur when industry is growing and moving towards more efficient capital intensive methods of operation. Seasonal unemployment, relates to fluctuations in demand for labour directly related to cycles in demand for final product. Tourism and leisure industries are the best examples, these can contribute to regional problems as they are strong in particular areas. Some of the remedies that government can use to reduce the level of unemployment are: direct increase in government spending on public infrastructure; encouragement of business investment by offering grants and loans; encouragement of exports; subsidise firms in financial trouble, guarantee jobs for workers facing redundancy and to restrict imports of competing foreign goods and also using specific measures to get people back into work like new deal programme and so on. The relation between unemployment and inflation can be explained with Philips curve, by Professor AW Philips in the 1862-1958. Philips observed that the rate of change in money wages was inversely related to the level of unemployment. Rising money wages were identified as a source of inflation and the inflation appeared to be inversely related to the level of unemployment. http://welkerswikinomics.com/students/wp-content/uploads/2008/08/fig21-300269.jpg Q4 The globalization and the environment are linked, because for expansion of economic, environmental damage are produced that are essential to the process of globalization. Mander argue that Globalization is a human creation that aims to remove impediments, such as environmental laws that restrict companies access to resources and markets, environmental damage is therefore an intrinsic part of the globalization system. www.gale.cengage.com/pdf/samples/toc32870.pd The intention of having a globalized world and to lower trade barriers, protecting free trade and my environment, thus bringing the economic development in poor countries, so that people have access to information, improving their health and liability to environmental protection. The process helps to globalize the ideas run free from one country to another, increasing the availability of knowledge and other opinions, helping the development among the nations. But for many environmentalists and anti-globalists Globalization will lead to environmental disaster and will gradually lead to the destruction of the environment, because the vision of globalization and produced without precedents to environmental deterioration. Speth points out that Since the end of World War II economic expansion has produced enormous environmental damage and global economic development can be expected to bring about even more dire economic consequences. www.gale.cengage.com/pdf/samples/toc32870.pd He believes that with globalization the few developed countries are benefiting because there was an opening up huge markets for them, since many of these poor countries produce more effective products and efficient, doing so will be multinationals are setting up in places, boosting investment foreign direct investment, and generating many jobs open to residents, e.g. Asian Tigers of South Korea, Taiwan, Hong Kong and Singapore demonstrated the great benefits of globalization and free trade. www.futureharvest.org/ news / globalization_pir. In the other hand, there is a great inequality and between rich and poor countries. Aislin It has been argued that poor countries are often exploited and pushed into the world trade forums. For example, it is evident when the rich nations are allowed to pay huge subsidies to their farmers, which leaves LDN is a disadvantage industrial Workers. http://www.abcnews.go.com/sections/politics/dailynews/TheNote_March5.html Q5 If imports goods are too high it may be possible to reduce demand for them in the economy by imposing tariffs to raise the price of imports goods to prevent unfair competition in the home market. Also to avoid buying product from the market were workers have been exploited to export their product cheap. This policy is likely to be met by retaliation from overseas countries, which will reduce exports putting the current account back into deficit. In addition, imposition of tariffs does not reduce expenditure if demand for imports is relatively inelastic, government policy favouring domestic suppliers may mean higher than necessary taxes to pay for the higher necessary purchase cost, and restrictions generally encourage smuggling and black market For example, a poor country that in main revenue comes from the tax on trade, if withdraw the tax trade its revenue will reduce significantly also the amount of investment on public infrastructure will be reduce, consequently many import goods may come into the market in a low price, causing the domestic goods serious problems on market as well as increase unemployment. The balance of payment also will be affected; because of lack of exportation it may cause government to borrow some money to balance the balance of payment.

The Aztecs :: essays research papers

The Aztecs The Aztec people ruled from the Gulf of Mexico to present day Guatemala. There capital city was Tenochititlan. The greatest controlling force was religion. It was shown in their architecture and sculpture.   They also had writing, numbers and a calendar. They had recorded dates for religious holidays. The children were taught respect, courtesy, truthfulness and self control. Aztec boys learned practical tasks from their fathers at home. Then when they reached 15 they went to a youth house. There elders taught the boys religion, citizenship, history, traditions and art. They also learned war. Girls could also learn to be priestesses in temple schools. The Aztecs were divided into tribes   that were dived into clans. Each clan had its own officials that represented them at tribal meetings. The land was dived up by the tribes. They controlled the land but the peasants farmed it having to give some of it to the chiefs and priests. The Aztecs worshipped a host of gods that represented nature. To win the gods aid they performed rituals and offered penance. Human sacrifice played an important role. Since life was a mans most valued possession it was the best thing to offer up to the gods. As the Aztec empire grew so did the human sacrifice. Sometimes the Aztecs performed cannibalism, believing they absorb the virtues of the slain. The sacrificed people were thought to be given a high place in heaven. The average Aztec was a farmer. He lived outside the city and grew crops for his tribe. Farming was the most important means of survival due to the warm, humid climate. They lived in small huts. The male was the head of the family. He would often arrange marriages for their children. The language they spoke was the Nahuan language that originated from the west coast of the united states. They wore elaborate colorful clothing made from animal skins that were traded from

Catechol Oxidase Lab

Catechol oxidase is an enzyme that speeds up the oxidation reaction when catechol is exposed to oxygen. When the reaction occurs, benzoquinone is produced turning the oxidized substance brown. It was hypothesized that the higher the concentration of catechol oxidase, the browner the substance will turn, and the faster it will achieve the color. In the present lab, different concentrations of catechol oxidase were mixed with pure catechol and the rate at which each solution browned was measured using a colorimeter.The results showed that the solution with the high concentration of catechol oxidase had the fastest rate at which it turned brown. However, it did not turn the brownest, the solution with the medium concentration of enzyme did. These results show that our hypothesis was both supported and not supported and it was concluded that increase in catechol oxidase concentration increases rate of turning brown but does not increase the level of brownness a substance becomes.Introduc tionHave you ever wondered why the inside of your apple turns brown if you leave it on the counter after taking a bite? This is because there is a compound within the apple called catechol which, when exposed to the air, becomes oxidized by the oxygen in the air and produces benzoquinone, which makes the apple appear brown (Andrew Clapper’s Online Journal, 2007). This chemical reaction is catalyzed by the enzyme catechol oxidase (Figure A.1). Enzymes are proteins in cells that speed up chemical reactions (Enzyme Procedure Guide, 2013). The catechol oxidase lowers the amount of energy needed in order for the catechol to be oxidized, which speeds the process up.Fig. A.1: The oxidation process of catechol with the help of catechol oxidase produces benzoquinone. (Enzyme Procedure PowerPoint, 2013)If you frequently eat apples you may have also noticed that different types apples brown at different rates. This is because each kind of apple has a different concentration of catechol oxidase (Daniela Finkel, 2013). Therefore, each apple has a unique speed at which it will produce benzoquinone, and turn brown.This experiment was designed to investigate the following hypothesis: The higher the concentration of catechol oxidase, the browner the substance will be, and the faster it will achieve the color (Enzyme Procedure Guide, 2013).Within the experiment, pure catechol was mixed with different concentrations of catechol oxidase and the rate at which each solution produced benzoquinone was measured. The amount of benzoquinone made throughout the trials was measured by using a colorimeter to measure the level of â€Å"brownness† of the liquid. The colorimeter worked by shining a light through the liquid and then measuring that light on the other side to see how much of it was absorbed.In this experiment, absorbance of blue light was measured because blue light is absorbed by the color brown. The amount of blue light absorbance was measured every 15 seconds fo r five minutes. Because enzymes speed up reactions, more enzymes would cause the reaction to be even faster.1Procedure/Materials and MethodsThe lab leaders and the Punk Rock Warlord prepared three different concentrations of catechol oxidase by extracting potato juice (because it contains lots of catechol oxidase). Pure catechol, a 5mL test tube, 1mL/5mL syringes, a colorimeter and water were also used. 4mL of pure catechol and 1mL of the highly concentrated catechol oxidase were measured with the syringes. Both liquids were then injected into the 5mL test tube. The 5mL tube was placed into the opening in the colorimeter and the lid of the  colorimeter was closed.The measure of absorbance of blue light displayed on the screen of the colorimeter was recorded every 15 seconds for five minutes. This procedure was repeated for two more trials, each with 4mL of pure catechol; one used 1mL of medium concentrated catechol oxidase and one used 1mL of low concentrated catechol oxidase.The independent variable was the concentration of catechol oxidase, the dependent variable was the rate of turning brown, there were no controls, there were three replications and the sample sizes were 11 (for high concentration) and 10 (for medium and low concentrations).Results SectionFigure 1 shows that before the rates began to plateau, the high enzyme concentration solution was turning brown the fastest. Table 1 shows that the high enzyme concentration had the fastest rate and that on average, it deviated from the mean more than the medium and low concentrations. Figure 2 shows that the high enzyme concentration solution was turning brown the fastest. Table 2 shows that the different rates each solution turned brown are statistically significant.Table 1: Average Rates of for High, Medium and Low Concentrations of Catechol Oxidase and the Absolute Average Deviations. Three different concentrations of catechol oxidase were added to pure catechol and the rate of change in the absorpti on of blue light (production of benzoquinone) was measured every 15 seconds using a colorimeter.

Rare Earth Elements (Metals) - List

Rare Earth Elements (Metals) - List This is a list of rare earth elements (REEs), which are a special group of metals. Key Takeaways: List of Rare Earth Elements The rare earth elements (REEs) or rare earth metals (REMs) are a group of metals found within the same ores and possessing similar chemical properties.Scientists and engineers disagree on exactly which element should be included in a list of the rare earths, but they generally include the fifteen lanthanide elements, plus scandium and yttrium.Despite their name, the rare earths arent actually rare with respect to abundance in the Earths crust. The exception is promethium, a radioactive metal. The CRC Handbook of Chemistry and Physics and IUPAC list the rare earths as consisting of the lanthanides, plus scandium and yttrium. This includes atomic number 57 through 71, as well as 39 (yttrium) and 21 (scandium): Lanthanum (sometimes considered a transition metal)CeriumPraseodymiumNeodymiumPromethiumSamariumEuropiumGadoliniumTerbiumDysprosiumHolmiumErbiumThuliumYtterbiumLutetiumScandiumYttrium Other sources consider the rare earths to be the lanthanides and actinides: Lanthanum (sometimes considered a transition metal)CeriumPraseodymiumNeodymiumPromethiumSamariumEuropiumGadoliniumTerbiumDysprosiumHolmiumErbiumThuliumYtterbiumLutetiumActinium (sometimes considered a transition metal)ThoriumProtactiniumUraniumNeptuniumPlutoniumAmericiumCuriumBerkeliumCaliforniumEinsteiniumFermiumMendeleviumNobeliumLawrencium Classification of Rare Earths The classification of the rare earth elements is as hotly disputed as the list of included metals. One common method of classification is by atomic weight. Low atomic weight elements are the light rare earth elements (LREEs). Elements with high atomic weight are the heavy rare earth elements (HREEs). Elements that fall between the two extremes are the middle rare earth elements (MREEs). One popular system categorizes atomic numbers up to 61 as LREEs and those higher than 62 as HREEs (with the middle range absent or up to interpretation). Summary of Abbreviations Several abbreviations are used in connection with the rare earth elements: RE: rare earthREE: rare earth elementREM: rare earth metalREO: rare earth oxideREY: rare earth element and yttriumLREE: light rare earth elementsMREE: middle rare earth elementsHREE: heavy rare earth elements Rare Earth Uses In general, the rare earths are used in alloys, for their special optical properties, and in electronics.

Reflective Paper Essays

Reflective Paper Essays Reflective Paper Essay Reflective Paper Essay Essay Topic: Reflective Doing volunteer work is a great way to get involved within a community. The Houston Food Bank is a place that had been in before. In my experience have found that really like to volunteer and I plan on going back in the near future. Volunteering has helped me in exploring my interests and abilities. It is through volunteer opportunities that I have learned how to communicate with others and acquire skills that can transfer into the workplace. When trying to find a job, employers look for volunteer experience because that just wows them thou take time out of your life to help others. I have also learned that the world does not revolve around me. There are many people in much worse situations that need help. Am grateful for the opportunities that have been given in life. I am fortunate enough to be in a position where am able to help those in need. Serving the community whether big or small will make a big impact on the lives of people that need it the most. By doing this we not only encourage others to volunteer, but we help the less fortunate arm a more positive outlook on life. Volunteering at the Houston F-DOD Bank this past Saturday saw how much productivity was done in just the four hours that was there. The workers are always enthusiastic and that just creates a welcoming mood for all who attend. Another thing that I like is that at the end of our volunteer hours the employees of the Houston Food Bank give the number of meals that is served from the work that the volunteers put in. Overall, I feel that volunteering helps me improve as a person. It is a great ay to serve a community as well as meet new people. Eel that everyone should volunteer it does not necessarily have to be at the Houston Food Bank but it should be in a place where they feel that their time will be well spent. I am glad I got the chance to volunteer because I feel better about myself knowing that I helped others and I look forward to many more opportunities. Attending the Houston Food bank has shown me that there is a lot of work to be done when it comes to helping out those in need . When it comes to eloping the community monetary contributions alone will not suffice. What people do not realize is that spending time rather than money is more rewarding in the long-run. The time spent in community service makes a person feel as though they have accomplished something big. Volunteering also shows the values that an individual may have such as generosity, compassion and a good heart. It also sets the example for others follow. I believe that everyone should give back to their community because volunteering will make the world a better place.

AMPACK Computer Company Computer Platform Upgrade Essay

AMPACK Computer Company Computer Platform Upgrade - Essay Example This will help in the transmission and processing of different computerized jobs at hand. To accomplish this, a server that will serve for internet connection provider and a file server need allocation in the office setup. All computer units must have LAN cards installed and a server router or network switch provided to mediate the connection. Once you know what type of computer hardware and software you will need, it is time for you to decide whether you want to purchase for a desktop or laptop computer. To help you decide, we will list the major advantages and disadvantages of both types of computers. The type of computer you choose will depend on how you intend to use it. A portable desktop computer platform is used on a typical office setup, which can be adopted in the company's system. However, laptops are also applicable in some departments preferably the managerial branch to have it transferable if corporate meeting presentation is needed or other similar cases. Portability is more important than performance, because you need to move the computer routinely, choose a laptop. If you will be moving the system very frequently, consider a smaller-sized laptop. Choosing the right Operating System for AMPACK office infrastructure is easily managed since there are current systems involved. Installing Windows XP for the workstation platform and windows 2003 for the server could minimize the current software needs of employees for production jobs. Most computer software needed to do the task involved in production, accounting, and managerial are mostly based on windows environment. Preferring to use this operating system would minimize cost for an over-all adjustment if a new operating system will be used. Not only minimizing the cost for software adjustment but also minimizes the cost for future technical training to staffs who physically involves with the workstations on their daily task. In relation to that, our server will be under the Windows 2003 Server system. The concern for this is the reliability, security and robustness compared to other operating system. Windows 2003 Server edition offers a complete solution for a typical server. T his comprises the file server, internet, printer, email, DNS and database server. If we will consider using Linux and other operating system, the employees will have to adjust to the environment, which they currently are familiar. Software adjustment will be costly if we will use other operating system. Some may say that other software is free or is cheaper than windows but the software and hardware compatibility is limited. The software needed in the company's daily task may not be compatible to other operating system. Thus, windows based systems are encouraged to install because of its wide-range of compatibility that meets the company's requirements. Other than windows and Linux, Macintosh would be an expensive option. Many people are unaware of how easy and inexpensive it is to interconnect existing computers to form a small Local Area Network (LAN). If you are using Windows 2000/XP, no additional software is required to benefit from basic network functions such as shared use of directories, drives, or printers and the hardware costs are minimal. A network can substantially simplify internet access for two or more people. Of course, another reason for setting

Japanese and Chinese Styles comparison Research Paper

Japanese and Chinese Styles comparison - Research Paper Example Japan’s offenses of omission in dealing fully with its past marks as hindrance to its present overseas policy, but they pale in contrast with China’s historical sense of entitlement to local hegemony and its strong new form of condition-sanctioned anti-Japanese patriotism. China’s tactful language emphasizes toeing party’s line history rather than discriminating present-day interests, and it presumes that only one position in international affairs more often than not China’s — can be correct (Hagstrà ¶m 9) China today has much more to gain from association with Japan than from disagreement. Harping about past inflaming and sins the disputes over the islands do little good. If republic of China is to become the main power in the region, it can only do so with Japan, not next to it. As Germany and France have confirmed, ideas can change when government’s interest demands it. But changing Beijing’s thinking from hierarchy to collaboration will require strong leadership and a nuanced indulgent of national interests. China’s new leaders haven’t inspired much hope of either (Hunt 17). Socially, Japan developed on the Shogun ate life in which society revolved around honoring the emperor while maintaining a familys personal respect. The samurai, compared to the knight in the western European society, was one of the most accepted figures in Japanese society. While Post-modern China was also imperial in nature, China went without the Samurai system and instead relied heavily on a national army and private army. China and Japan both claim to be the shareholders of over  East China Sea  islets that China calls it the  Diaoyu Islands and Japan refer to it as Senkaku Islands. Tensions have been high from 2012 September, when Japanese government acquired three of the islets from private Japanese proprietor. This leads
