Book Review American Slavery: 1619-1877 by Peter Kolchin

â€Å"American Slavery, 1619-1877† by Peter Kolchin gives an overview of the practice of slavery in America between 1619 and 1877. From the origins of slavery in the colonial period to the road to its abolition, the book explores the characteristics of slave culture as well as the racial mind-sets and development of the old South’s social structures. This paper is divided in two sections.The first section observes the author’s vivid presentation of the slave-master psyche and relationship from the 17th to 19th century America. The second section examines the author’s choice of method in narration – how, apart from quoting statistics, Kolchin gave weight to accounts of slaves’ and slave owners’ lives and conditions. Delving into the Peculiar Institution of Slavery American slavery, Kolchin explains, didn't develop in isolation, but evolved as part of a trend toward forced labor in the New World colonies.By about 1770, American slavery w as concentrated mostly in the South, though it existed in all of the American colonies, and, as time passed, relationships between slaves and masters changed as second- generation slaves lost much of their African culture and became Americanized. The Revolutionary era saw slavery threatened by Enlightenment ideology, but the institution survived more strongly than ever in the South and, during the 19th century, came to be perceived as fundamental to the Southern economy and way of life.Kolchin also writes about slave life through the Civil War, and, not surprisingly, he sees slavery as leaving a legacy that has persisted throughout our own century. Kolchin probes into the lives of those imprisoned by the â€Å"peculiar institution† of American slavery. It begins with slavery’s origin in America in the sixteen hundreds, with the importation of slaves from Africa. Their free labor established the agricultural foundation of the New World. From hereon, Kolchin follows the escalation of slavery through citing statistics and providing information of conditions of the lives and times of slaves and slave owners.Kolchin narrates tales of hardship and provides a condemning opinion of slavery. At the same time, however, he focuses on the facts of daily living of slaves in America. Furthermore, Kolchin delves deeply into the oddly fascinating dynamics of the slave-master relationship, which allows incidents such as a master whipping his slave for working sluggishly and then the evening of the same day, gathering all of the slaves for a bible reading session. A person who provides basic needs for others but forces them to provide him free labor in return is evaluated repeatedly in the book with interesting outcomes.However, the author likewise presents a slave owner who had minimal impact on slaves’ lives outside of the workday, one who allowed the slaves to have social and religious celebrations of their own choosing, and viewed the slaves as not just property, but humans. The irony of this is that slave owners saw no wrong in what they were doing, regardless of how they treated their respective slaves. Slavery, as an institution, was from the perspective of the slave owners, justified.Kolchin describes that, in response, slaves were overtly resistive to their predicament at times, while others provided less obvious resistance in the form of slow work, feigning illness, and even sabotage. In addition, Kolchin gives the readers the catalysts for the events in the history of slavery. Economic, religious, and social factors are made prevalent, which renders the book well organized and able to reach depths that a few other books with the same topic failed to achieve. Even though the war ended, hatred for blacks remains.Thus, segregation evolves in full force throughout the nation, but mainly in the south. He also explains the struggle of the south to compete with the north as far as industrialization which was the new course of Amer ica straying away from agriculture, and until today they still suffer a lack of industry opposed to the northern states. Method of Narration The book’s chronological format of the book provides a logical flow and allows the reader to see the manner by which the events of each day made tremendous impact on slavery.The bibliographical essay lists hundreds of books that pertain to the writing in a sectional format and describes particular topics covered in each book. This is easy to see in the straightforward and matter-of-fact way that the author discusses topics from whipping of slaves, to the selling of slaves resulting in the breakup of families. Kolchin effectively used statistics in writing this book, in that, at the start of most sections or chapters the reader was able to ascertain the slave population and distribution, as well as growth rates and comparison to white population.Kolchin’s interpretation of this particular historic era shows that its’ history is primarily determined by individuals with economic motivations. When the author wanted to explain the horrors of these situations, he used quotes from slaves themselves, not a personal soapbox that many authors use. By using these comparisons the reader can see how the treatment of slaves was paramount to production, controllability, and even reproduction. ConclusionPeter Kolchin’s â€Å"American Slavery, 1619 – 1877,† provides a laudable and significant consideration of slavery in the formation of the United States as a country. It is a clear and briskly written survey that puts slavery in context and explains its continuing impact on American life. Overall, Kolchin displays an excellent work of literature which provides many sources and well-thought-out information. Reference Kolchin, Peter (1993). American Slavery, 1619-1877. Hill and Wang

Software Customization

Business software was fabricated to intentionally make the company processes much easier, efficient, accurate and more convenient for the users. Today, these software are now ready for modifications to suit the business needs of a particular company. Apparently, software customization is considered to be a social modification process (Clement) which affects many segments of people’s day to day activities The customization of a business software is applicable only if it can justify the reasons for such modification. As examples, it would only be more ideal to customize a software if the company has found a more productive way of doing business or if the company is protecting any of its intellectual property rights for a particular product. The main benefit of software customization in a newly discovered mode of production is that the software can minimize possible delays and errors in doing the said procedure because of the fact that its function will directly support the task. On the other hand, a customized software can also provide a form of security for intellectual product rights because the customized program will only be useful for a particular segment of the company’s production line. Although software customization provides a larger scale of benefits, there are also some related concerns. For one, customizing a pre-defined program may require the company to invest in hiring an expert programmer to initiate the customization. Also, it is a necessary thing to train the in-house programmers for the customization so that the procedure can be maintained. These factors may all involve additional financial investments for the company. Moreover, customization also carries a certain amount of risks for it my not readily identify some erroneous procedures the software my induce in other unidentified company processes. On a personal note, it seems that the most fundamental advancement in personal computing is the introduction of the internet. Previously, anything that needs to be done using a machine assistant was only confined in a limited area of computing. However, today’s capacity of the computers to transmit and receive data in split second speeds has allowed many individuals, organizations and industries to exchange information which primarily drives today’s social development. Basically, the advanced capability of PCs and the internet have definitely improved how business, education and communication are being implemented. References Clement, A. N.D.

Arugmentative essay on which is better the pc or the mac computer

Arugmentative on which is better the pc or the mac computer - Essay Example Both fruit would have supporters lauding the differences in inherent nutritive value, taste, and texture of each. When we compare an Apple Mac to a MS Windows PC, two traditional feasible choices for personal and business computing, though, the subjective should be thrown out of the window and the facts wisely considered. While it is true that Windows has been ‘virally’ (pun intended!) popular, the time has come for certain misconceptions about the Mac to be cleared up and how it will be a very good choice. The inevitable argument against the Mac is that it is more expensive than a Windows PC. While at times true, the fact is it often costs less than or about the same as its Windows counterpart. A Windows PC’s cost does not include multimedia software and hardware that you will need or want. By buying the extras, you pay more than the cost of a Mac which comes bundled with software like iLife. Consider long-term savings: Macs have been proved to be less expensive to run than Windows. The reputable CIO magazine quoted an Enterprise Desktop Alliance survey as finding the total cost of ownership (TCO) with a Mac to be much lower than a Windows PC. â€Å"Macs were cheaper in six of seven computer management categories: troubleshooting, help desk calls, system configuration, user training and supporting infrastructure.† (Kaneshige). Almost half the respondents reported licensing fees were about the same on both these platforms. In 2002, Apple, introduced the OS X, an operating system (OS) based on UNIX. Specialists consider it one of the most advanced, stable and secure OSs available commercially. It is a multimedia sensation thanks to its architecture and graphics. Users find the OS X smart, agile and a delight to use. In comparison Windows OSs have been compared to bulky, lumbering giants plagued by crashes requiring restarts that cost time and money. In Windows if you erroneously shift a folder or a file such as a program file

Culture Jamming Essay Example | Topics and Well Written Essays - 750 words

Culture Jamming - Essay Example Photoshop and interceptions-counter-messages. Over the years, jammers argue that they usually do not alter ad’s message but are exposing, improving, correcting or rather modifying them. A billboard artist, however, said that an excellent jam does not directly rescript a precisely different meaning but drafts the deeper message of substitute advertisement. Jamming is only a productive act if done to the right of the society; Rodriguez de Granada is an example of a jammer with the well-meant intention of the same. Jamming disagrees with marketing as a one-way conveyance of information; people should have the right to respond to images they did not ask for their display. Rodriguez de Granada , one of the founders of jamming was a highly skilled and innovative jammer. Rodriguez, a 31-year-old man, would be seen in the city of New York altering ads in broad daylight. The reason to why he was not arrested was because he would reason out with the police why he did talking them out of arresting him in a couple of incidences. Rodriguez de Granada jammed for a good course, and unlike other artists, he did not fancy the term guerrilla art but termed it as, citizen art. He believed practicing jamming in daylight was a regular mode of communicating with the society democratically. Rodriguez explains his main reason for jamming was to wipe out advertisers habit to glamorize hard alcoholic products and addictive drugs like tobacco on billboards. Ads on beer and cigarettes featured provocative models that create an enticing image in children’s mind especially those living in the ghettos felt compelled to elope. Rodriguez de Granada argued the importance o f jamming was to the culture at large. He intended his work to be a part of the community’s way of life; he wanted people to engage in his work. Children stood to watch as he transformed ads while others participated e.g. holding the ladder for him while he. He wanted

Boston Fights Drugs Individual Case Assignment 2 Study

Boston Fights Drugs Individual Assignment 2 - Case Study Example 2. Would you have selected focus groups as your research methodology? Why/Why not? List the pros and cons of using focus groups in this situation, as well as the pros and cons of the other suggested methods in the case For such a sensitive issue, the student group should not have selected a focus group but, rather, they should have chosen the on-on-one interview. While the focus group allows people to exchange ideas, the answers they give could be impacted by peer pressure (Mitchell & Jolley, 2013). For the one-on-one interview, there would have been minimal peer pressure, the participants would have the opportunity to talk more, and could even encourage participants to share information that would have been otherwise not shared in a focus group. However, it is more expensive and requires more time for data collection (Mitchell & Jolley, 2013). The pre-screening questionnaire was devised to ensure broad representation of the entire Boston population, while partially disguising why the focus group was being conducted. Questions required participants to identify their favorite commercials, as well as their take on street violence, attitudes on drugs, and personal habits (Rangan, 1994). The interview protocol acted as a guide to direct the discussion to the researcher’s topics of interests. Given the budgetary and time constraints, the group did well in participant screening. However, this did not allow them to pick focus groups from all Boston neighborhoods as they focused on only four neighborhoods and selected a sole young adult group using the pre-screening questionnaires. In the sampling procedure, the student group sought help from Boston officials to recruit participants from various city community schools. They also divided the population into four groups, which were addicts, active users, recreational users, and non-users (Rangan, 1994). Due to a lack of resources to track all the

Big Data Challenged and Opportunities Assignment

Big Data Challenged and Opportunities - Assignment Example It is evidently clear from the discussion that with big data, the problem of storage arises because of the fact that cloud storage has been seen vulnerable now to many security issues. With the data increasing day by day, it can be seen that people in the Information technology field are decreasing which causes an alarming situation to recruit talented people in the field. Information can be used for various positive purposes and scientific advancements can lead to the growth for a far better future. Where there are positive impacts and the world is moving towards a more digitalized form, there are drawbacks to the same thing which might lead to damage of both research and the society providing it falls into the wrong hands and is manipulated for the wrong purposes. The processing power and the storage capabilities of the technology for big data should be met with to improve understanding of nature. Big organizations have been using big data to gain advancements and lead the industry as compared to the other competitions in the industry. The aim to be the best at what they do, big data in industries is to be analyzed so that the big organizations can have an edge over all the other competitors in the same marketplace. Competition is what leads to growth and betterment. Striving for the best and maintaining the position is what keeps the companies moving forwards and progress in what they do. Analyzing big chunks of data not only gives out an upper hand as compared to the others but it also helps in making up strategies that are developed for the future working process and functioning of the organizational body. Having said that, the management system and lean management lead to the function of a more effective organizational body. It has become mandatory to develop future strategies on analytics and statistics of the company rather than by intuition.  

War of 1812 Essay Example | Topics and Well Written Essays - 750 words

War of 1812 - Essay Example Britain was engaged in war with France and wanted to curtail the trade capability of its enemies thus cutting trading channels (Wait 42). At the same time, Britain had implemented a forced recruitment of US seamen in to Royal Navy and started assisting Native American Indians who were engaged in forced resistance of the expansion of US frontier to the North West. The other immediate cause of the war was the desire by the United States to annex Canada territory and expand its frontier Northwest through conquering the Indians (Norton, et al 627). Over several decades, Americans developed the feeling that the Mexicans had very little respect for the young United States. Besides, Mexicans prompted arrogant attacks to the United States and this created a lot of hostility to both nations. Even though the war got official, declaration in June 1812, preparations for engagement in such kind of an attack was already in place with the government congress inviting more volunteers to join the mil itary and the number was rapidly increasing (Black 118). American Indians had cordial relations with the British as a way of building up power to fight against a common enemy. This led to a military support since Britain offered weapons to the red Indians in order to suppress United States military from invading the northwest region that had fertile soil and natural resources (Wait 42). The possible resistance of invasion of the territory from both sides was as an imminent factor to stage the war later named the Mexican war. There was anxiety because the United States had a composition of two major armies. The fist one termed as the United States Amy seconded by the one authorized by the congress. Therefore, the congress army was set up with an agenda to wage wars in order to restore dignity and honor from the nations as one of the strongest forces in the world and it was through this, that the Mexican war came into place as a solid test to determine the strength of such an existenc e (Hanson 31). The United States achievements from the Mexican war Despite objections by the abolitionists, the United States gained recommendable boost on military confidence and mighty since volunteers who joined the forces to help fight enemies. Their military populations remained the same even after the war had technically ended and the US was considered a military power. In addition, the Indians having being supported by the British with the sophisticated weapons, finally agreed to sign treaties in order to allow for United States frontier expansion in Northwest. The United States asserted its trade independence under the international law and need for neutral rights of the countries engaged in the war. Later, Mexican government accepted to a fine charge for having assaulted the United States and agreed to pay a debt amounting to more than three million United States dollars (Wait 42). Conclusion I believe that the United States attained high military confidence by defeating a force that was large and superior in terms of military equipment to the United States and President Jackson demonstrated to the entire world that the US was a powerful military force. Although the signing of treaty after British defeat at New Orleans technically ended the war, the United States attained nationalism and was capable of signing treaties in Northwest thus opening the Native Indian lands for American expansion. Accordingly, the US asserted its trade

Currency Hedging Essay Example | Topics and Well Written Essays - 5500 words

Currency Hedging - Essay Example For example investors bank their hopes on relative net returns such as Net Dividend Yield (NDY) generated by stock related investments. Thus potential investors look at how the growth trajectory of Net Asset Value (NAV) would increase in keeping with net returns in relatively less risky spheres of investment. Secondly the risk factor associated with currency market related investments is proportionately higher when foreign exchange related investments take a plunge due to uncertain government policies. For example if the government concerned allows its own currency to depreciate externally in order to correct a deficit in the trade balance of the balance of payment, investors would be caught on the wrong foot if they happen to bank their hopes constantly on the continuity of government policy (Maskey, 1995). Thirdly the government may adopt anti-inflationary measures such as higher corporate taxes and expenditure taxes. The net result would be less investment and less borrowing. Currency markets become dormant during such periods of negative policy initiative. Foreign exchange rates and interest rates ... s are positively related because when interest rates fall the exchange rates also fall because potential foreign investors do not buy the domestic currency concerned for investment when the domestic interest rates fall and as a result the demand for the domestic currency abroad falls thus leading to an unfavorable exchange rate (Larsen, & Resnick, 2000). Hedge funds, mutual funds, pension funds, commercial banks and other money market players have a tendency to hedge risk by minimizing the degree of exposure to adverse consequences arising from unfavorable exchange rates, inflation and investment related uncertainties such as a continuous fall in stock prices (Biger, & Hull, 1983). 2. Analysis 2.1. What is Currency Hedging Currency hedging has become a very controversial issue in modern money market operations (Adler, & Prasad, 1992). Commercial banks and other market players have adopted highly strategic exclusive policy initiatives to deal with the problem. This paper investigates the relative efficacy of such highly complex approaches to currency hedging adopted by different market players, while at the same time focusing attention on the doubt expressed by modern writers about the benefits of currency hedging strategies to all market players at a given time.Currency hedging is a technique that is meant to manage and reduce the risks involved when engaging in some foreign investment strategy. Essentially the very nature of a currency hedging effort would be more beneficial in obviating the negative outcomes from any shifts in the relative value of the currency as utilized in the investment process (Levy, & Lim, 1994). This is intended to shield the investor from negative shifts in the money market so that even if the currency involved takes a plunge

NEC Assignment Example | Topics and Well Written Essays - 500 words

NEC - Assignment Example hnology and specialization advanced rapidly, it became more difficult for companies to harness all necessary technologies through their own R&D activities. Consequently they were forming strategic alliances with other firms, laboratories and universities that held competitive edge technologically (Mark 1987). There were several proposed sites for NEC including Boston, Palo Alto and Princeton. Shinoda and Kahng believed it was necessary to establish the laboratory at a relatively quiet place and thus it was conducive to establish the site in Princeton. The closeness of Princeton to Europe was significant for constant communication to the headquarters in Europe. It was essential for NEC to move out of Europe in order to diversify its market and exploit new markets in the globe. Princeton was a strategic position for the development of the company owing to the accessibility of resources. The region having other scientific institutions such as the Bell Laboratories, the IBM Research Institute, and the SRI Institute would facilitate NES with new knowledge that would be essential in establishing of a successful achievement of set objectives. Princeton would also be a convenient place to do collaborative research; this is because of the easy access to universities such as the Princeton University, Columbia University and Yale University. These Universities would greatly help in carrying out research for the firm. I think locating the industry in a region that has other firms already established would be essential for ease in access by clients because clients are already aware of the company’s location. The competition by other similar firm would greatly assist the firm to borrow and make reasonable improvements. Many companies tend to focus on both research and development activities all together; this is not the case with NEC. NEC prefers to entirely focus on research activities alone in the international research center; this decision is accompanied with a number

The value of the information you find on the internet Essay Example for Free

The value of the information you find on the internet Essay You are asking some very good questions. I often wondered the same before I learned about this subject. I would be glad to answer your questions and tell you what they all mean. First, you ask ‘How to assess the value of the information you find on the internet’? Well, there are many ways to assess the information you find on the internet. The first of many ways that I use to assess this information is to check the author information, meaning is the author trustworthy. To do this I often will see if the author has background in the subject that I am researching. I think that by doing this the information written by those who do not have any experience in the subject will not be on my radar. This also allows you to determine whether or not an author is authentic. Another important thing to check to see if information is reliable is to check the date, checking the date will help you determine if the information is up-to-date and if it has been updated recently. I think that by making sure the information is not outdated will help the credibility of this information. thing to check to see if information is reliable is to check the date, checking the date will help you determine if the information is up-to-date and if it has been updated recently. I think that by making sure the information is not outdated will help the credibility of this information. Another thing you would need to check is the website dependable. When I say ‘dependable’ I mean is the website easily edited by others who do not have any experience in the field? Has this information edited recently, and by whom? When using the internet you must be cautious of the information you read because some information could be false. You also ask about the ‘digital divide’ and what it means. The best way I can describe it is the divide between people who are up to date with all of the technological advances and those who are not. The people who are up-to-date with all of the technology advances have many ways to access all volumes of modern media though the internet. Whether it is though the use of a smart phone or the use of a computer or another type of technical device, whereas the people who do not have access to these types of media, people who rely on more traditional media such as, newspapers, books, and magazines would be on the opposite side of the digital divide. To bridge the digital divide all people would have to be able to access all versions of mass media. Meaning everyone would need to have to have equal  access to the internet. By that I mean that everyone should have access to the internet. Whether at home or otherwise would be keeping everyone in the technological world would definitely help Bridge the gap in the digital age.

Maths Teaching Guide: Algebraic Expressions

Maths Teaching Guide: Algebraic Expressions 6 Algebraic Expressions You know to write the terms, coefficients and factors of an algebraic expression. to classify an algebraic expression as monomial, binomial, trinomial. to identify like terms. to add and subtract algebraic expression. You will learn multiplication and division of given polynomials. the difference between an identity and an equation. algebraic identities and their applications. factorization of algebraic expression by regrouping , by taking common factors or using algebraic identities. Let us recall the basic definitions of algebra Constants and variables : A quantity having a fixed numerical value is called a constant whereas variables in algebra are letters such as x, y, z or any other letter that can be used to represent unknown numbers. Algebraic expression : An expression which has a combination of constants and variables connected to each other by one or more operation (+,-,X,à ·) is called an algebraic expression. Example are all algebraic expressions Term : The parts of an algebraic expression separated by an addition or a subtraction sign are called terms of the expression. In the expression the terms of the expression are are variable terms as their values will change with the value of x, while (-4) is a constant term. On the basis of the number of terms in an algebraic expression, they are classified as monomials, binomials, trinomials and polynomials. Monomials are algebraic expressions having one term . Binomials are algebraic expressions having two terms. Trinomials are algebraic expressions having three terms. Polynomials are algebraic expressions having one or more than one term. Remember – Only expressions with positive powers of variables are called polynomials. An expression of the type is not a polynomial as and the power of variable p is (- 1) which is not a whole number. Example 1 Classify the algebraic expressions as monomials, binomials or trinomials. Solution binomial monomial trinomial monomial binomial Like and Unlike terms : Terms having the same algebraic factors are called like terms . The numerical coefficients may be different. 2x2yz, 5x2yz, 8x2yz and 2x2yz are like terms 3p 3q2, 7p 3q2and 9p 3q2 are also like terms. Unlike terms : Terms having different algebraic factors are called unlike terms, , 3x2yz 3p 3q2 are unlike terms. Addition and Subtraction of Algebraic Expressions. In algebra, like terms can be added or subtracted. To add or subtract algebraic expressions we can use the horizontal method or the column method. The horizontal method All algebraic expressions are written in a horizontal line; the like terms are then grouped. The sum or difference of the numerical coefficients is then found. Example 2 Add the following Solution Example 3 Subtract Solution The column method In the column method, each expression is written in a separate row in such a way that like terms are arranged one below the other in a column. The sum or difference of the numerical coefficients is then found. Example 4 Add : Solution To add by horizontal method, collect the like terms and add coefficients. To add by column method, arrange the like terms in column and add Example 5 Subtract : Solution We know that the subtraction of two algebraic expressions or terms is addition of the additive inverse of the second term to the first term. Since the additive inverse of a term has opposite sign of the term, hence we can say that in subtraction of algebraic expressions change + to – and change – to + for the term to be subtracted and then add the two terms To subtract by column method, arrange the like terms in columns and change the sign of the subtrahend Example 6 What should be added to to get Solution The expression to be added will be Exercise 6.1 Classify the algebraic expressions as monomials, binomials or trinomials. Also write the terms of the expression Add the following algebraic expressions by the horizontal method Add the following algebraic expressions. Subtract the following expressions. Subtract the sum of from the sum of . Two adjacent sides of a rectangle are . What will be the perimeter of the rectangle. The perimeter of a triangle is and the measure of two sides is. What will be the measure of the third side? What should be added to to get . What should be subtracted from to get By how much is greater than . Multiplication of Algebraic Expressions Multiplication of a monomial by another monomial To multiply 2 monomials Multiply the numerical coefficients Multiply the literal coefficients and use laws of exponents if variables are same. The product of two monomials is always a monomial. Example 1 Find the product of Solution Geometrical interpretation of product of two monomials The area of a rectangle is given by the product of length and breadth. If we consider the length as l and breadth as b, then Area of rectangle = l x b Thus, it can be said that the area of a rectangle is product of two monomials. Let us consider a rectangle of length 4p and breadth 3p, Area of rectangle ABCD =AB x AD = 4p x 3p = 12p2 Multiplication of a monomial by a binomial To multiply a monomial by a binomial, we use the distributive law Multiply the monomial by the first term Multiply the monomial by the second term of the binomial. The result is the sum of the two terms The product of a monomial and a binomial is always a binomial. Example 2 Find the product Solution Example 3 Multiply Solution Geometrical interpretation of product of a monomial and a binomial Area of rectangle = l x b Let us draw a rectangle ABCD with length (p+q) and breadth k. Take a point P on AB such that AP = p and PB = q. Draw a line parallel to AD from the point P, PQà ¢Ã‚ «Ã‚ ½AD meeting DC at Q. Area of rectangle ABCD = area of rectangle APQD +area of rectangle PBCQ = k x p + k x q = k(p + q) Thus, the product k(p + q) represents the area of a rectangle with length as a binomial (p+q) and breadth as a monomial k. Multiplication of a monomial by a polynomial To multiply a monomial with a binomial, we can extend the distributive law further The product of a monomial and a polynomial is a polynomial. Example 3 Find the product of Solution We have multiplied horizontally in all the above examples We can also multiply vertically as shown below Multiply Geometrical interpretation of product of a monomial and a polynomial Let us consider a rectangle with length = (p +q + r) and breadth= k Take points M and N on AB such that AM = p and MN = q and NB = r .from the points M and N draw parallel to AD, MXà ¢Ã‚ «Ã‚ ½AD and NYà ¢Ã‚ «Ã‚ ½AD meeting DC at X and Y. Area of rectangle ABCD = area of rectangle AMXD +area of rectangle MNYX +area of rectangle NBCY Area of rectangle ABCD=pk + qk + rk = k(p + q+ r) Thus, the product of a monomial and a polynomial represents the area of a reactangle with length as a polynomial and breadth as a monomial. Example 4 Simplify Solution Multiplication of binomials To multiply two binomials (a + b) and (c + d) we will again use the distributive law of multiplication over addition twice Example 5 Multiply Solution We have multiplied horizontally in all the above examples We can also multiply vertically as shown below Multiplication of polynomial by a polynomial A polynomial is an algebraic expression having 1 or more than one term To multiply two polynomials, we will use the distributive property that is multiply each term of the first polynomial with each term of the second polynomial. Example 6 Multiply Solution We have multiplied horizontally in the above example, We can also multiply vertically as shown below Exercise 6.2 Multiply the following monomials 2a and 9b Find the following products and evaluate for x = 1, y = -1 Find the following products by horizontal method Find the following products using column method Find the area of the rectangle with the given measurements Length = 3p, breadth = 4p Length = (2a+4), breadth = 5a Multiply the following Simplify the following expressions Multiply . Simplify If the length of a rectangle is and breadth is 3abc,find the area of the rectangle. Algebraic identities An identity is a special type of equation in which the LHS and the RHS are equal for all values of the variables. The above equation is true for all possible values of a and b; so it is called an identity. An identity is different from equation as an equation is not true for all values of variables,;it has a unique solution. Example There are a number of identities which are used in mathematics to make calculations easy. We are going to study 4 basic identities Verification of identities in this identity a and b can be positive or negative Geometrical verification of identities Geometrical demonstration for. Draw a square with length as shown in the figure. Let the area of original square be X then, area of Square PQRS=(side)2 ∠´ , Mark a point M on PQ such that length of PM = a and length of MQ= b. Draw a line MC parallel to PS intersecting SR at C. Similarly, mark a point B on RQ such that RB = a and QB = b. Draw a line BD parallel to QP intersecting PS at D. The whole square is divided into 2 squares and 2 rectangles say A1, A4,A2and A3 Area of Square X1 = side2= a2 Area of rectangle X2= length x breadth = ab Area of rectangle X3= length x breadth = ab Area of Square X4 = side2= b2 area of Square PQRS = sum of inside area = area of X1+ area of X2+ area ofX3+ area ofX4 Geometrically demonstration for . We draw a square with length a as shown in the figure. Let the area of original square is A Then, area of Square PQRS=(side)2 ∠´ Mark a point M on PQ such that the length of PM = a-b and length of MQ= b. Draw a line MC parallel to PS intersecting SR at C. Similarly, mark a point B on RQ such that RB = a b and QB = b. Draw a line BD parallel to QP intersecting PS at D. The whole square

Understanding The Misunderstood Art From Different Cultures :: essays research papers

Understanding the Misunderstood Art From Different Cultures Art is a medium used by people world wide to express their ideas, their fears, and their joys. The artist takes the experiences of life and translates them into a visual object, rich in colors, shapes and sizes, for all the world to observe. As a casual observer of art, one is able to relive the feeling or experience the artist was trying to display, if only for a brief moment in time. No matter what cultural background one comes from, art appreciation and enjoyment erases the barriers and the limits, and allows cross-cultural understanding and appraisal. Art has always relied heavily upon universal symbols. One of the most well known universal symbols is the cross, meaning of course, religion. Religion of a culture is one of the most frequently misjudged and stereotyped aspects From the prehistoric times of the cave man to present day, art has depicted religious scenes native to a specific culture. This is where most of the cultural boundaries lie. To one person, a smiling monkey can instill a primal feeling of fear, while to another the first reaction is one of amusement. This difference in reaction is based upon religious upbringing, and nothing more. To certain culture, a smiling monkey is the scariest thing they could ever imagine, and to another, it means laughter. A close minded person viewing an ancient religious mask would see nothing more than nonsense, while one who wishes to understand art would see the beauty of that culture and it's beliefs, and would try to place themselves in a way so that they may understand the original meaning ofthe mask, and form an educated opinion on it. Anyone can enjoy a piece of art, but what is it that makes a piece of art "good"? Is it the realism of the piece? Or the absolute perfectness of a sculpture? Maybe good art is abstract, an array of shapes put together to make a point. Or maybe good art is a classical sculpture that catches the light just so and brings a warm smile to the viewers face. Is it a measure of craftsmanship? A measure of mediums used? A measure of technique? Or is it just a measure of how it affects the viewer? Is good art visually irritating or visually pleasing? The beauty of art is impossible to define, for it's beauty inherently lies in the eye of the beholder. As Georg Wilhelm Friedrich Hegel said, "Beauty is the spiritual put into a form." So, in defining beauty, one is attempting to define the spiritual beliefs behind the form.

Resturant Law Essay -- essays research papers

In the business world every business has its own set of laws and regulations to follow and adhere too. Some have very few laws and others have so many it is mind numbing but, each law is set up to protect every worker, customer or person associated with that business’s location. However, some of these laws are outdated or just plain unnecessary in today’s 21st century business environment.   Ã‚  Ã‚  Ã‚  Ã‚  The business that I chose to examine is the restaurant industry. I chose it because I have a great love for cooking and I hope to someday open my own restaurant. It made great sense to learn some of the laws now while still in school that could impact my future business endeavors. First I will review the laws and regulations pertinent to the restaurant business and then I will explain the impact of those laws on the restaurant business.   Ã‚  Ã‚  Ã‚  Ã‚  The first laws that I found were the laws from OSHA. OSHA contains many laws that are designed to create a safe workplace and keep workers out of situations that can be potentially harmful. Without OSHA many workplaces would be a lot more unsafe than they are now. OSHA reduced the number of work place injuries and deaths, making it one of the most important sets of laws to govern all business and especially the restaurant business.   Ã‚  Ã‚  Ã‚  Ã‚  OSHA calls for two different types of fire prevention equipment to be placed in all restaurants. First it calls for automatic sprinklers to be installed per OSHA standards. These standards are that they have a certain spraying pattern, densities, water flow that can cover the whole area that it is above. After meeting those specs the business then has to get the system to meet water supply standards. Basically the standard is that the system has a water supply that can flow for thirty minutes.   Ã‚  Ã‚  Ã‚  Ã‚  The next statute that must be met is the piping needs to be protected from freezing and corrosion from the surrounding environment. This assures that if a fire occurs the piping will be able to take the water pressure that is flowing through to the sprinkler system. Also it calls for the system to have a proper drainage system that allows the system to drop the water from the sprinkler system and then have it drain back into a reservoir. The final statute from OSHA 1910.159 is that the sprinklers be space... ...and not even paid in a way that allows them to live in a normal way.   Ã‚  Ã‚  Ã‚  Ã‚  There is only one change that I feel the Department of Labor should enact. That is a raise in the minimum wage. Many friends I have work so hard for their $5.25 and never really have much to show for it. If the minimum wage was raised many people who are working two part time jobs to make ends meet would have a better chance of making those ends meet. Not to mention raising minimum wage could spur the economy by placing more spending power into the hands of the demographics that tend to spend the most, the youth of America.   Ã‚  Ã‚  Ã‚  Ã‚  In this country we have seen the world of business change over and over. As the country has grown so has the need to keep our workers safe and happy. The laws I have discussed are meant to keep the restaurant industry a safe and happy place for the many people who work in them day in and day out. Without those laws the restaurant industry would not be a very healthy or safe place to frequent as much as American people do. So each of the laws are essential to making the industry profitable and safe.   Ã‚  Ã‚  Ã‚  Ã‚  

Personal Trainer, Inc. Essay

Background You are enjoying your job as a student intern at Personal Trainer. Last week, Susan asked you to help her plan the new information system project. Susan knows that you have completed several information systems courses at the local college, and that you have studied project management tools and techniques. Specifically, she wants you to get ready for the next set of systems development tasks, which will be requirements modeling for the new system. Yesterday, Susan called you into her office to discuss the specific tasks she wants you to perform. After meeting with Susan, you sit down and review your notes. She wants you to treat the set of tasks as a project, and to use project management skills to plan the tasks. Here is what she suggested to you as a work breakdown structure, including the duration she estimated for each task: First, you need to meet with fitness center managers at other Personal Trainer locations (10 days). After these meetings, you can conduct a series of interviews (8 days). When the interviews are complete, two tasks can begin at the same time: you can review company records (2 days) and observe business operations (7 days). When you have reviewed the records and observed business operations, you can analyze the BumbleBee accounting software (3 days) and study a sample of sales and billing transactions (1 day). You are excited about the opportunity to practice your skills, and you start to work on the following list. Personal Trainer, Inc. Fact-Finding Summary A typical center has 300-500 members, with two membership levels: full and limited. Full members have access to all activities. Limited members are restricted to activities they have selected, but they can participate in other activities by paying a usage fee. All members have charge privileges. Charges for merchandise and services are recorded on a charge slip, which is signed by the member. At the end of each day, cash sales and charges are entered into the BumbleBee accounting software, which runs on a computer workstation at each location. Daily cash receipts are deposited in a local bank and credited to the corporate Personal Trainer account. The BumbleBee program produces a daily activity report with a listing of all sales transactions. At the end of the month, the local manager uses BumbleBee to transmit an accounts receivable summary to the Personal Trainer headquarters in Chicago, where member statements are prepared and mailed. Members mail their payments to the Personal Trainer headquarters, where the payment is applied to the member account. The BumbleBee program stores basic member information, but does not include information about member preferences, activities, and history. Currently, the BumbleBee program produces one local report (the daily activity report) and three reports that are prepared at the headquarters location: a monthly member sales report, an exception report for inactive members and late payers, and a quarterly profit-and-loss report that shows a breakdown of revenue and costs for each separate activity. Assignments 1. List the system requirements, with examples for each category. Review the information that Susan gathered, and assume that she will add her own ideas to achieve more effective outputs, inputs, processes, performance, and controls. The system requirements for the new Personal Trainer system can be identified by careful analysis of the fact-finding summary on page 184. The summary contains a number of â€Å"must† statements, and various items on the â€Å"wish list† that were suggested by local managers and staff members. Students should be able to identify, classify, and enumerate these items. Sample suggestions for outputs, inputs, processes, performance, and controls might include the following: Outputs: Report on delinquent payments, more frequent reports on trends and profitability, computerized activity and wellness log, more detailed exception reports, what-if scenarios that managers can use to plan promotions and discounts Inputs: More information about member preferences, activities and history, method to obtain member suggestions and e-mail messages Dr. Rafael Nieves Page 4 Processes: Automated process to scan key chain IDs or credit cards, process to manage part-time instructors and staff Performance: New design for sales slips, better information on members Controls: Standardized coding system to be used company wide, better  reconciliation of data, and creation of audit trails 2. Are there scalability issues that Susan should consider? What are they? Scalability refers to a system’s ability to handle increased business volume and transactions in the future. Because it will have a longer useful life, a scalable system offers a better return on the initial investment. To evaluate scalability, Susan will need information about projected future volume for all outputs, inputs, and processes. For example, she would need to know the estimated number of customers, transaction volume, peak periods, number and types of data items required for each transaction, and the method of accessing and updating customer files. 3. If Susan wants to conduct a survey of current or prospective members to obtain their input, what type of sampling should she use? Why? Students might suggest a stratified sample of former members and prospective members. It is relatively easy to identify former members from Personal Trainer’s records, but it might be more difficult to identify prospective members. Several options are available. Personal Trainer might request survey input from members who have recommended friends in the past. Were the new members happy, and did they remain as members? Why or why not? This might be quite valuable input in predicting future membership results.  Also, perhaps the company has a list of people who have requested information about Personal Trainer in the past, but never signed up for a class. That group might be an interesting sample. Finally, former students might be an interesting group to survey. 4. Draw an FDD that shows the main operations described in the fact statement. The fact-finding summary on page 184 identifies many of Personal Trainer’s activities, functions, and processes. Answers will vary based on different perceptions of Personal Trainer’s main operations.

Position of the leader Essay

In every team endeavor someone formally or informally takes the position of the leader. A leader keeps track of all the team activities and has a deciding effect on the workings of the team. He has to care not only about the work but also its speed of execution. As team is composed of people, this means he has to get the work done with the people and as always observed; people work when they have some motivation to do so. Motivation is the key to how people react to a particular work or situation. A good leader very well knows what is the motivation behind each of his team member’s work and uses it for the maximum benefit of the team. Some of my motivations are holidays and spending time on my hobbies. I am also motivated by being a part of process of some positive change and also if I get chance to work with small, relaxed, honest people. These form the major crunch of my motivation. I believe that things that motivate me will very well motivate others also. I find the theory Y approach1 useful. In it the workers are assumed to be happy with their job and use their creativity and imagination to make decision and to solve problems. These set of people will tackle problem themselves as far as possible and remain satisfied with their work because this gives them opportunity to do the work as they like. Of course, some people fall in the theory X category, I prefer to throw out such people and if that’s not possible try to turn them to Y side. Also I find the ‘Maslow’s hierarchy of needs’2 quite useful. He mentions that everyone is motivated by his needs but once his needs are met, He isn’t satisfied instead it is taken over by another higher need. A leader has to take care of the needs of where his people are in this hierarchy. References: 1 Douglas McGregor (1960). ‘The Human Side of Enterprise’.

The Prelude – William Wordsworth

Fardad Hajirostami Guilty Conscience In his poem, â€Å"The Prelude†, William Wordsworth relives a childhood epiphany that alters his perception of nature. Wordsworth describes this experience of his through his voyage in a boat which later dramatically turns into a nightmarish journey. Through use of suspenseful diction, dramatic personification, and descriptive syntax, Wordsworth vividly illustrates his perception of nature and how he views it with certain trepidation after he encounters a â€Å"towering† and horrific figure.The opening lines of the poem immediately personify nature as having a feministic quality. When Wordsworth stumbles upon a boat and unloosens its chain, he describes this incident as an â€Å"act of stealth and troubled pleasure†. Wordsworth in a way foreshadows possible dangers that are lurking in the near future due to his guilty conscience. This guilty conscience can also be interpreted as a consequence of the sexual seduction of nature and the boat as suggested by the author’s syntax and tone.The author’s mentioning of the boat as â€Å"an elfin pinnace† and the description of how he â€Å"lustily †¦ dipped [his] oars into the silent lake† confirm the author’s premature and lascivious tendencies. Wordsworth’s attitude towards the relationship that he shares with the boat also infers a sense of egotism and overconfidence. He describes himself as â€Å"one who rows, proud of his skill, to reach a chosen point with an unswerving line,† with a â€Å"fixed† view. Wordsworth’s syntax and his choice of the words â€Å"fixed†, â€Å"chosen† and â€Å"unswerving† all further develop and emphasize his haughty youthful character.Later in the poem, when Wordsworth witnesses a monstrous black figure appearing on the horizon that seemed to acquire an â€Å"utmost boundary†, a sudden shift in tone and diction takes place. The authorâ €™s seemingly control of nature and his sexual dominance is abruptly stolen away from him due to a symbolic black figure that in a way represents Wordsworth’s guilty conscience and childhood illusions. In addition, the author has lost his composure and â€Å"proud skill† in the way he paddles away with â€Å"trembling oars†. The incidence of this daemon figure completely transformsWordsworth’s tranquil and lustful relationship with nature into a dreadful and outlandish one. Wordsworth’s earlier intimacy with nature transforms to â€Å"solitude† and â€Å"blank desertion†. The author’s perception of nature contrasts with that of the Romanticists. The â€Å"familiar shapes† are no longer prevalent and â€Å"no pleasant images of trees† or â€Å"colors of green fields† linger in the author’s conscience. The author’s anticipation of possible dangers that seemed inevitable due to the suspensefu l nature of the poem did not compare to the extent of such an episode.A key distinction between the author’s perceptions of nature earlier and later in the poem arises in the extent in which he personifies it. Initially, nature was illustrated as possessing an inert quality and a mere existence. This connotation suggested that he controlled nature’s way and determined its fate. Later, however, this earlier notion of his is altered once â€Å"a huge peak, black and huge† appears on the horizon. The â€Å"voluntary power instinct† of the figure implies that it has acquired unnatural and humanistic qualities and thus haunted the author’s dreams.Wordsworth’s description of nature can be interpreted as Wordsworth’s childhood sexual fantasies with feminine figures while the black figure symbolically represents religious condemnation of his society at the time. The morals and customs of the society in which Wordsworth lived in presumably dis dained the sexual desires of the youths. Consequently, Wordsworth unconsciously fears the black figure and interprets it as a force that has come to punish his unfitting and lustful behavior.

Cardiorespiratory Focus On Hypertension Health And Social Care Essay

The scenario concerns the survey of blood force per unit area scientific discipline and ordinance in the content of high blood pressure. Following, each aim is stated and so analyzed. A 31 twelvemonth old adult male goes to his GP because he has started to hold terrible concerns that come on all of a sudden at assorted times during the twenty-four hours. He is a fiscal analyst who works in a bank in Canary Warf. Many of his co-workers have been made redundant but he has kept his occupation, although his line director has made it clear that he may lose it in the following few months if the state of affairs does non better. He says he works at least 15 hours a twenty-four hours and his matrimony is enduring because of this. He is seeking to give up smoke ( 1-2 battalions per twenty-four hours ) but the emphasis of work has made this hard. He goes with friends out to a wine saloon on a regular basis and admits to imbibing to a great extent one time or twice a hebdomad. Further oppugning reveals that his male parent died aged 61 from a shot. On scrutiny he is found to hold a BMI of 34 and a blood force per unit area of 190/125 mmHg. Retinal scrutiny shows some abnorma lcies ( â€Å" silvering † ) in the blood vass. After look intoing the blood force per unit area reading on two farther occasions the GP suggests that his jobs are related to conceal blood force per unit area and refers him to the local high blood pressure clinic. After undergoing farther trials at the clinic he is started on drug therapy and given lifestyle advice. What is blood force per unit area and how is it regulated? Oxford medical dictionary defines blood force per unit area as â€Å" the force per unit area of blood exerted on the walls of blood vass † ( 1 ) . The maximal blood force per unit area exerted during systole when blood enters the aorta is called â€Å" systolic † whereas the minimal force per unit area exerted when aortal valves near during diastole is called â€Å" diastolic † . Figure 1 shows the alterations in force per unit area in aorta during cardiac rhythm bespeaking the systolic and diastolic force per unit areas. Fig. 1 – Systolic and diastolic force per unit areas ( 2 ) Blood force per unit area in the organic structure must be maintained in the normal degrees non merely to keep perfusion of blood to all the organic structure but besides to forestall unwanted complications due to high blood force per unit area. Therefore, the blood force per unit area should stay inside a scope of values. However, blood force per unit area frequently changes. During physical exercising higher force per unit area facilitates greater perfusion in the musculuss providing them with more O. Blood force per unit area depends on two chief parametric quantities: Cardiac end product ( C.O ) : Cardiac end product which is the sum of blood pumped from the bosom per minute depends on the shot volume and the bosom rate. Entire peripheral opposition ( T.P.R ) : It is the entire opposition exerted by the peripheral vasculature. This chiefly depends on the radius of the vass – narrower vass exert greater opposition. The above are linked with the undermentioned equation: M.A.P = C.O x T.P.R From the above relationship it is obvious that by altering the values of C.O or T.P.R the blood force per unit area ( average arterial force per unit area ) can alter every bit good. Based on this, three chief mechanisms are used to modulate blood force per unit area when it lies outside the normal scope: Neuronal system – Baroreceptors This is chiefly used for short term ordinance of blood force per unit area. Baroreceptors are detectors found in the internal carotid arteria ( carotid fistula ) and on the aorta ( aortal fistula ) ( 3 ) . These are detectors that can observe differences in stretch in these arterias bespeaking differences in blood force per unit area. These detectors are innervated by the Vagus ( X ) and glossopharyngeal ( IX ) nervousnesss which travel up to cardioinhibitory and vasomotor centre in the myelin of the encephalon. Increase in blood force per unit area ( high blood pressure ) increases the fire of baroreceptors to the vasomotor centre. This causes a lessening in the sympathetic nervous outflow doing relaxation of the arteriolas, therefore diminishing T.P.R. In add-on, the cardioinhibitory Centre increases the parasympathetic activity decelerating down the bosom rate, therefore cut downing C.O ( 4 ) . Consequently the M.A.P is decreased. The contrary applies when blood force per unit are a is low ( hypotension ) . Figure 2 is a diagrammatic representation of the baroreceptor physiological reaction. Fig. 2 – Baroreceptor physiological reaction ( 5 ) Hormonal system – RAAS system This system is for longer term ordinance of blood force per unit area every bit good as blood volume. Figure 3 presents the Renin Angiotensin Aldosterone System.AldosteroneSecretionAngiotensinogenAngiotensin IIAngiotensin IFig. 3 – RAAS ( 6 ) In the kidneys Low Na concentration in the distal tubing, which indicates low blood force per unit area, is detected by sunspot densa cells. Furthermore, autumn in nephritic perfusion is detected by the juxtaglomerular setup. A bead in either of these two causes the release of renin from the kidney. In the pneumonic circulation renin is used to change over angiotensinogen to Angiotensin I. Angiotensin I is so split into Angiotensin II which is a vasoconstrictive. It besides acts on the adrenal secretory organs to let go of aldosterone. Aldosterone is a endocrine that increases the synthesis of Na+/K+-ATPase, therefore increasing Na and H2O resorption. On the whole, this mechanism increases both the volume of the blood and T.P.R to overall increase the force per unit area ( 7 ) . Atrial Natriuretic peptide ( ANP ) This is once more a hormonal manner of blood ordinance. Specialized atrial myocytes can feel increased stretching of the atrial walls of the bosom due to increased blood volumes. These let go of the ANP endocrine which decreases the release of chymosin in the blood ensuing in a lessening in the activity of RAAS. In add-on, it causes increased force per unit area in the capsule of the kidney by coincident relaxation of the afferent arteriola and bottleneck of the motorial arteriola so as to increase glomerular filtration rate. Define and sort high blood pressure. How is high blood pressure measured? WHO on its ain definition of high blood pressure states the followers: â€Å" Blood force per unit area, like tallness and weight, is a uninterrupted biological variable with no cut-off point dividing normotension from high blood pressure. The uninterrupted relationship between the degree of blood force per unit area and cardiovascular hazard makes any numerical definition and categorization of high blood pressure slightly arbitrary. Therefore, a definition of high blood pressure is normally taken as that degree of arterial blood force per unit area associated with doubling of long-run cardiovascular hazard † ( 8 ) High blood pressure can be classified in different ways harmonizing to the standards of categorization. Depending on the cause high blood pressure is classified in ( 9 ) : Essential – Primary high blood pressure: the cause in unknown. Secondary high blood pressure: there is an underlying obvious cause. Depending on the existent blood force per unit area degrees, British Hypertension Society guidelines sort Hypertension as presented on the tabular array below ( Fig.4 ) : Fig. 4 – British Hypertension Society categorization of blood force per unit area degrees ( 10 ) Sphygmometer is used to mensurate blood force per unit area of the brachial arteria. However, a individual elevated reading on scrutiny does non bespeak high blood pressure. This might be due to anxiousness and addition of sympathetic activity. This state of affairs is called the â€Å" white coat syndrome † . As a consequence, blood force per unit area must be measured more than one time every bit good as measured at place when the patient is relaxed. What are the physiological causes of high blood pressure? To get down with, it is indispensable to understand the scientific discipline behind the haemodynamics in order to be able to understand the physiological causes of high blood pressure: Independently of the cause, high blood pressure develops as a effect of one of the followers: High Intravascular volume: This means that there is a high volume of blood in the circulation that increases the venous return in the bosom. Consequently, this increases the preload and therefore the C.O taking to elevated blood force per unit area as described in the first aim. High intravascular volume may be due to increased H2O and salt keeping because of high angiotonin II and aldosterone concentrations, or nephritic tissue harm. Increased venous return: In this instance the intravascular volume is normal but there is increased venous tone which once more increases the venous return to the bosom. Abnormal arterial wall: This implies either reduced radius of arterial lms or decreased conformity. The first is true in increased sympathetic activity and atheromatous plaques formation. The latter is true in reduced snap and collagen replacing due to increased age or harm due to substances such as smoke. Merely 5-10 % of instances have an underlying obvious cause of high blood pressure. As mentioned earlier high blood pressure is categorized based on cause as follows: Essential In indispensable high blood pressure there is no obvious cause for high blood force per unit area. There is a assortment of hazard factors taking to this type of high blood pressure that will be explained subsequently. Different researches over the old ages have concluded to some theories that might explicate indispensable high blood pressure. These are ( 11 ) : High sympathetic tone: Increased sympathetic tone even when the individual is relaxed causes vasoconstriction of the arteriolas and finally hypertrophy of the smooth musculus in the vass. High salt in diet: High salt in diet has been related to keeping of H2O, increased blood volume and therefore high blood pressure Stress: As in our instance, emphasis increases the activity of sympathetic system. Stress for long periods causes hypertrophy of smooth musculus in arteriolas and contracting of their lms so that high blood pressure remains even in stress free periods. A combination of the above may be. Secondary Secondary high blood pressure may hold several causes as explained below: Nephritic disease: On one manus secondary high blood pressure may be due to stricture of a nephritic arteria. This triggers the RAAS system and increases blood force per unit area. On the other manus there may be devastation of the nephritic tissue taking to inability of kidneys to egest necessary sum of H2O or salt taking once more to high blood pressure. Endocrinological tumors: Tumours of secretory organs that secrete endocrines such as aldosterone. Hyperaldosteroinism ( Conn ‘s syndrome ) can take to hyper-secretion of aldosterone doing greater resorption of H2O and Na than normal ( 12 ) . Congenital aortal deformity: This is constriction of aorta which is fundamentally the narrowing of aorta, ensuing in reduced nephritic perfusion and activation of the RAAS system Combined Oral preventive pills: This is a type of drug induced high blood pressure. In this instance oestrogen administrated as a portion of the preventive pill acts as a vasoconstrictive and besides increases angiotensinogen ( 4 ) . Eclampsia – Pregnancy: Although the grounds behind this are non wholly clear, pre-eclampsia may be due to placental disfunction every bit good as immune response of the female parent against the placental tissue conveying about high blood pressure ( 13 ) . Hazard factors There are a figure of hazard factors responsible for developing high blood pressure which have been supported by a assortment of surveies. A survey published on 2006 based on informations collected on a population of American Indians indicates some of the undermentioned as hazard factors for high blood pressure ( 14 ) . These can be extrapolated for the general population. Hazard factors are non merely familial but besides environmental factors. Most of the below are true in our PBL scenario: African lineage Sexual activity gender – males: A research published late on Hypertension diary provinces that mistake signals in commanding of the sympathetic system exist between the two genders giving differences in the controlling of blood force per unit area ( 15 ) . Increasing age Low societal category High salt consumption, high fat diet Stress Fleshiness Chronic conditions such as diabetes, nephritic diseases, sleep apnoea. High intoxicants intake Smoking No exercising What are the symptoms and what are possible complications of high blood pressure? High blood pressure is known as the â€Å" soundless slayer † as most of the times is symptomless until it develops sudden complications such as shots or bosom onslaughts that can take to decease ( 16 ) . Often, the high blood pressure is non detected until a random look into up modus operandi is taken. However some people may see the followers: Dizziness Blurred vision ( due to damage of the retina of the oculus ) Concern Long-standing high blood pressure will finally do coronary artery disease with all the possible effects of the disease. Furthermore, it causes reconstructing – hypertrophy of the bosom taking to more dangerous state of affairss. Serious complications of high blood pressure are: Nephritic decease ( 17 ) : It can take to weakened or narrowed blood vass in kidney impairing its map. Stroke: Vessels of the encephalon may split or non good perfused taking to stroke. Heart onslaught: The bosom has to work harder to pump blood against greater force per unit area. This may develop bosom failure and inability of the bosom to pump blood to cover organic structure ‘s demands. Aneurysms: May do pouching in arterias taking to tearing them Vision loss: Due to damage of the little fragile vass of the oculus. What are the intervention and lifestyle alterations for the patient? A combination of drug intervention and lifestyle alterations is necessary for bar of the complications listed above ( 18 ) . The following table lists interventions and the mechanism they work. Drug Category Drug name Mechanism ACE inhibitors Enalapril They block the transition of angiotensinogen to Angiotensin I and therefore barricade the RAAS. Diuretic drugs Thiazides They increase the sum of H2O and salts excreted in the piss so that they decrease blood volume. I ±-blockers Doxazosin They work by barricading I ±1-adrenoreceptors on the walls of blood vass so that they cause vasodilatation. I?-blockers Atenolol They block I?1- adrenoreceptors on the bosom diminishing bosom rate and shot strength, therefore diminishing cardiac end product and finally force per unit area. CaC blockers Nifedipine They block the Ca channels forestalling Ca come ining the cell. As a consequence they prevent vasoconstriction. In add-on to the drug therapy the patient has to watch his diet by cut downing the Na and fat consumption. Exercise should go portion of his life and surcease of smoke and restricting intoxicant ingestion are necessary. Patient has to restrict his emphasis every bit much as possible and regular monitoring of blood force per unit area can be life salvaging.

Environmental Impacts of the Global Increase in Demand for Oil Essay

To what extent are the environmental impacts of the global increase in demand for oil acceptable? [15 marks] After the industrial revolution, the demand for oil has been increasing globally. Over 100 million tonnes of oil are transported around the world on average a day. There are countries like the US which consume almost one quarter of global oil output, which must be supplied from oil reserves, usually from countries like Saudi Arabia (Guinness, 2011, p. 245). This shows that the topic of oil consumption is a global issue as all countries need oil to develop and provide for their populations. The issue with this large consumption of oil is the fact that oil is a non-renewable source of energy and therefore has a limit. Oil is formed from the remains of dead plants and animals in underground rock which is found in marine areas and therefore requires technology such as pipelines and drilling machines to extract the oil. The implications of this has caused serious environmental consequences which questions whether extracting oil to supply the demands of the world’s population should be permitted when the environment has to pay the cost, examples being oil leaks into the sea and the effects of that. With a growing global population, energy companies are trying to find sources of energy and are therefore trying to construct pathways and routes to constantly feed people’s needs and demands. This has lead to companies searching and drilling for oil in fragile environments, such as the Alaska pipeline which crosses 3 mountain ranges. The reason why companies are looking into areas full of permafrost is because global warming is causing the ice in the Arctic Circle to melt and oil rich sea beads are now being uncovered. The implementation of the Alaska pipeline has not caused any major environmental problems as many obstacles had been avoided when constructing this project, such as raising the pipeline on stilts so that that the heated oil would not cause the ice to melt. However, the Exxon Valdez oil spill in Alaska, which occurred in 1989 did take place and still affects the environment, animal species and humans to this day. The oil tanker named Exxon Valdez was carrying 1.2 million barrels of oil when it ran aground on Bligh Reef in Prince William Sound, spilling 240 000 barrels. The oil slick eventually covered 25 000 km2 coastal and off-shore waters and 1700km of coastline (RGS Worcester, n.d., para. 2). A major oil spill like this has resulted in devastating environmental impacts, which has caused social and economical impacts as well. The clean-up process, which included burning the oil (relatively effective as it reduced 113,400 liters of oil to 1,134 liters of removable residue), spraying chemicals on the oil which reached the shoreline and mechanical cleanup methods, did not eradicate the oil fast enough as the environmental impacts are still present after 21 years. 10000 people were involved in the clean up and it took 4 summers and cost 2 billion dollars. This large number of people put their jobs on hold and attended to the effects of the oil spill, which could have caused a decline in the economy in Alaska (Exxon Valdez oil spill, n.d., para. 5). The biggest impact of the oil spill was on the wildlife. Some 2,000 sea otters, 302 harbor seals and about 250,000 seabirds died within a few days after the oil spill (Graham, 2003, para. 1). A decrease in biodiversity and the ecosystems in Alaska affect the environment significantly as it disrupts food chains and causes animals like ducks and other marine animals to lose their source of food. The biggest impact, in terms of wildlife, is the herring population and the effect on the herring industry in Alaska. The spill occurred during spawning season that the inlets and bays where herring traditionally laid their eggs were choked with oil. Within four years, the herring population has disappeared. This has affected Alaskans in terms of their jobs and their source of food. Permits to fish herring commercially had been worth hundreds of thousands of dollars before the spill but became worthless, leaving many fishermen facing huge amounts of debt. Farmers used to earn 150000 dollars a year but this has dropped to 5000 dollars, showing the extent of the impact of the loss of herring (BBC News, 2010, para. 9). A weaker economy results in economical problems within the area and a change in employment structure as children of these fisherman can no longer have the opportunity to be a herring farmer. Economic problems can also result in social problems such as domestic violence, alcohol abuse, suicides and divorces, mainly due to massive unemployment. This example shows that the environmental impacts can have their own impacts, which again questions whether the extraction of oil is worth all these consequences. After 21 years, 20000 gallons of oil still remain on the beaches of Prince William Sound (BBC News, 2010, para. 30). Therefore, the clean up hasn’t been very effective. It’s also worth pointing out that maybe all the environmental impacts still haven’t been determined, for example the soil and vegetation could also have been affected by the oil spill as the oil may have seeped through the sand of the beaches. This would affect the growth of vegetation drastically. People don’t know enough to predict how long the effects are going to last as they can range from years to centuries. One wonders how long countries can continue to extract and consume oil when they still don’t fully know the extent of the environmental effects of oil spills and if their chances of occurring are more likely. The production of oil is also a process which causes a variety of negative effects on the environment. An example is the tar sands oil extraction in Canada – the country which supplies the US with the most oil as it doesn’t have issues regarding transport, weather and the fact that there are pipeline installed from Canada to the US. There is enough natural gas to heat 3 million homes from the extraction of tar sands oil in Canada. However, it is expensive to extract the oil out of the sands (120 million dollars over the last 12 years have been invested) which has lead to environmental degradation in the form of excess use of water to extract bitumen. The bitumen is then refined and the toxic sludge (not like conventional oil – mainly nasty impurities) that is left over after separating oil from impurities is usually dumped in ponds and lakes. In some cases, the toxic ponds are so big that they can be seen from space. The Athabasca River in Canada has a large number of toxic ponds, some being 60 km long in length. These companies, like SUNCOR (Canadian energy company), are dumping around 1.8 billion liters of toxic materials like sludge and impurities in these ponds, they will eventually reach water in the delta (Sustainable Guidance, 2011). The effects of these impurities in the water can be devastating to the wildlife. There is a decrease in the number of fish as the sludge clogs up the fish’s gills, making it hard for them to breathe. The change in the ecosystem and food chain will also cause a decline in fish as smaller species like plankton may be affected by the impurities. The fish may also be contaminated and migratory birds which eat these fish will suffer and possibly die as they won’t eat healthy meat. Moose is another species which are affected by the toxic ponds as their source of food is contaminated and decreasing. This has lead to a number of endangered species. There is a 35 million acres coniferous forest (larger than the Brazilian forest) which is full of endangered species. There have also been cases where environmental issues like toxic ponds are not released to the public as these details have been ‘covered up’ by companies like SUNCOR, leaving environmentalists like Green peace in conflict with these energy companies. This example has shown the harmful effects of oil production on the environment, which again makes us question whether this is all worth it (Sustainable Guidance, 2011). To a very small extent, the environmental impacts of the global increase in demand for oil are acceptable. It can be said, with great certainty, that oil production and consumption does not benefit the environment. The environmental consequences may not be frequent but when they do occur, they cause a catastrophic effect, which takes the environment and the people decades or even longer to recover. These impacts are therefore not acceptable, which is why countries should start investing in producing renewable energy such as solar panels and wind turbines. Governments can’t suddenly start decreasing the amount of oil they consume as the people are already used to living with a high standard of living. The populations around the world should be educated about the problem and should be encouraged to start relying on renewable sources of energy. However, this raises the problem for developing countries and NICs. It will be extremely difficult to develop without consuming large amounts of oil and will therefore cause the rate of development to decrease. This leaves these types of countries at a disadvantage, which questions whether it is acceptable for all countries to consume a smaller amount of oil when there are countries with different levels of development. Clearly the issue needs to be discussed before any strategies can be implemented. References BBC News. (2010, July 6). Alaska town slowly heals after 1989 Exxon Valdez spill.

Micro enterprises - Essay Example equires ethical values that will enable them treat the workforce equally, regardless of the gender, race, religion, culture and abilities (Harvey, 2012). Through adopting a non-discrimination policy, the leaders can afford to treat all the members of the workforce with equality, thus promoting the feelings of appreciation amongst the workforce. The creation of teams and groups that embraces and comprises of different elements of the workforce serves to promote the management of diversity, in that all the members of the workforce feels considered and represented in the groups and teams. Valuing and considering the contributions made by all members of the workforce serves to make the workforce more vibrant, creative and innovative, in that they feel that their ideas and inventions will be recognized and appreciated by the organization (Jeffs, 2008). Receiving and treating the grievances and the concerns raised by members of the workforce, without discrimination or favoritism on any basis that creates diversity in the workforce, is another successful step towards having the leaders of the macro enterprises manage the diversity of the workforce specializing in decision support system (Harvey, 2012). Through the effectiveness of diversity in the workforce, the leaders are assured of a motivated team, which guarantees success. Some characteristics are relevant for small business to be considered as appropriate in the selection process for developing the decision support systems. A small business requires being technologically oriented, an aspect that serves to ensure that the business is in a position to test and try novel technological innovations, ensuring that they can develop a system that is most appropriate for the business (Power, 2002). This is most essential since technology keeps changing and the types of decisions to be made are dynamic, thus calling for constant improvement in the business DSS so established. Another requisite characteristic of such a

International Law Essay Example | Topics and Well Written Essays - 4000 words

International Law - Essay Example Treaty law essentially entails the same binding nature as custom, and is only distinguished from custom because it is more formal than the former.2 However, treaties are generally written law and as such is a more certain source of international law.3 Although some international law scholar refer to treaties and customary international law interchangeably, there is a clear distinction since customary international law is bereft of written law and treaties are identified with written instruments. For example, Article 2(a) of the Vienna Convention on the Law of Treaties 1974 proves that: ‘treaty’ means an international agreement concluded between States in written form and governed by international law, whether embodied in a single instrument or in two or more related instruments and whatever its particular designation.4 In this regard there are two types of treaties under international law that represent important sources of international law. The first kind of treaties i s law-making treaties that establish rules that are universally and generally applicable. The second kind of treaties at international law are â€Å"treaty-contracts† which are concluded between two or more states and cover specific issues relative to the contracting states.5 Law-making treaties are direct sources of international law, while contract-treaties merely outline treaty obligations between the contracting states and thus circumvent the need to identify and apply customary international law, unless the treaty requires the application of customary international law.6 Since the mid-19th century there has been an unprecedented proliferation of law-making treaties which have come to be known as â€Å"international legislation†.7 The proliferation of international law-making treaties was responses to the inefficiency of international customary law in meeting the immediate needs of the international community for the regulation of mutual interests. The immediate ne eds of the international community arose out of developments at the economic and industrial levels which were increasingly tightening the interconnectedness of states. Thus relationships between states became more complicated and diverse.8 Law-making treaties can be viable alternatives to customary laws because as history informs, law-making treaties typically serve to main functions. First they may articulate crystalized rules of international law, thus making customary law more visible and essentially codifying customary law into an identifiable source of law. Secondly, law-making treaties may identify new issues and formulate new rules of international law designed to respond to new issues or to change current practices by states.9 For instance, UN Law of the Sea Treaty 1982 establishes new rules relative to jurisdictional parameters applicable to the seas.10 The UN Law of the Sea Treaty 1982 also codifies some customary rules of international law. However, the 1982 Treaty also p rovides new provision such as the creation of the International Sealed Authority for controlling the distribution of marine resources. Moreover, transit passages were established for replacing the concept of innocent passage via coastal states’ territories. Thus states ratifying the 1982 Treaty would necessarily be bound by new international laws relative to the distribution of marine life and transit passages.11 Thus law-making treati

Qatar Exchange Term Paper Example | Topics and Well Written Essays - 500 words

Qatar Exchange - Term Paper Example This sector currently has a total of eighteen firms listed in the Qatari stock exchange thus presenting it as one of the most successful sectors in the Qatar market. The consistent growth of this sector has always been attributed to the higher lending associated with higher scale of infrastructural projects. The slated 2022 FIFA world cup in Qatar has also stimulated a high growth in the investment projects making the sector the best performing at the moment (Qatar, 2014). The Insurance sector: this sector has 12 firms listed on the stock exchange market and is rated as one of the best performing sectors in the Qatar’s economy. This sector has been receiving annual growth rate of at least 11.3% from the year 2008 outlining how well the sector is performing. Due to the weakening demands on major expensive claims such as personal accident claims and health insurance, the growth has maintained a steady rise making the sector among the very best performing (Qatar 2010 Phase 1). The services sector: this is another very well performing sector in the Qatar’s stock market with a total of 15 firms listed in the stock exchange market. The net profit realized by this sector grew to 21.0% in the first quarter of 2014. The single largest contributor to this was the Qatar fuel company posting a 12.3% rise in their own net profit. The industry and Hotel sector: this sector has 17 firms listed in the Qatar stock market. Even though the profits from this sector reduced by 7.3% in the first quarter of 2014, it is still able to contribute 27.2% of the of the Qatar’s total market profit. This drop is mainly attributed to the extended planned closing, the general increasing costs and the product price deflation (Qatar 2010 Phase 1). The individuals of firms that are interested in trading in the Qatar Exchange in form of buying and selling of the shares listed must first of all follow the laid down

Reflective analysis of counselling practice task Essay

Reflective analysis of counselling practice task - Essay Example Such behaviour annoyed her sister, and they were not in good terms since then. My aim in this counselling session was to assist the client never to be such emotional and depressed. In this context, I was to get the real cause of the depression and emotional that appeared on my client’s face to help me effectively counsel the client. However, I realised I was so inconsistent with the client-centred theory as the client was willing to talk and share a lot with me but the best I offered was a mere hug. For example, I kept on saying ‘Mhhh’ instead of inquiring and looking for best strategies counsel my client by showing empathy and congruence. I terribly failed to assist my client. I was so inconsistent and asked questions out of the client-centred theory such as whether she was still willing to talk to her sister who was unhelpful. I realised that the emotional degree in the client shuttered my session and could never appreciate the congruence and empathy as outlined by the client-centred theory. In my session, I failed to be driven by the three key pillars of client-centred theory as empathy, unconditional positive regard and congruence. I never appreciated the fact that every individual has internal resources necessary for the growth and, therefore, my person-centred counselling approach would have helped me provide the three mentioned pillars that help realised such stated growth. In mind, throughout the session I failed to appreciate the principle view of person-centred approach to counselling that an individual client is perceived as there own best authority on the experience as well as it perceives the client, the client in this case as being fully capable of fulfilling her own potential for growth. Rodgers says, ‘If am truly open to the way life is experienced by another person†¦. If I can take his other world into mine, then I risk seeing life in his or her way†¦ and of being

Business and Society - Leadership and Motivation Coursework

Business and Society - Leadership and Motivation - Coursework Example The steps taken in managing failure include managing cash flow, avoiding debt and developing an effective business plan. Leadership and motivation are important determinants of success in a business entity. Effective leadership guides employees towards the achievement of the entity’s goals and objectives (Caroll and Buchholtz 35). Additionally, employee motivation helps improve employees’ productivity resulting in an overall improvement of the firm. Leaders are different from managers in various ways. Leaders focus on people while managers focus on structure. Leaders innovate while managers administer (Caroll and Buchholtz 42). Leaders inspire trust while managers control. Retired General Colin Powell defines leadership as followership. His definition of leadership is accurate since leaders act in a way that inspires those that follow them. I agree with his definition of leadership is all about inspiring one’s followers. There are various leadership styles including bureaucratic, charismatic, servant and transactional (Caroll and Buchholtz 45). The style I prefer most is servant leadership since the leader leads since it considers employees’ participation. The style I prefer least is bureaucratic leadership since it inhibits innovation, creativity and flexibility. Dr Phil’s and Maslow’s Hierarchy of needs can be used to motivate and manage employees. Employee motivation increases their productivity (Caroll and Buchholtz 47). It is clear that money is not the sole motivating factor, other aspects including the working conditions impact employee management and motivation. An organization is a social unit of individuals that is designed and managed to pursue collective objectives (Caroll and Buchholtz 7). The specific characteristics of an organization include an organizational culture and the ability to work towards collective goals and objectives. Corporate culture refers to behaviours, beliefs and values that establish how a company’s management interacts with its employees and how it handles any external transactions.  Ã‚  

Taxi Driver by Julia Phillips and Michael Phillips Essay

Taxi Driver by Julia Phillips and Michael Phillips - Essay Example However, mise-en-scene techniques and slow moving camera shots soon reveal Travis’s point of view, positioning a subjective view of Travis’s world. The film uses camera movement and cinematography together with mise-en-scene at the outset to establish the tensions that build up to the violence. The film opens with the credits in the foreground of a taxi coming out of the steam of a street at night. A montage reveals rain beating against the taxi’s windshield. In the meantime, the yellow taxi is accented by rain and neon lights that bring it into sharp focus. Travis’s eyes can be seen moving from one image outside of the taxi to another as he travels Times Square and 42nd Street. The viewer sees what Travis sees: prostitutes, couples, and pornographic theatres visited by men. The camera alternates from the inside of the Taxi where Travis’s watchful eyes are moving and observing, to outside of the taxi to show the audience what Travis sees. These scen es are juxtaposed against a more tranquil, ordinary and inescapably artificial world. The camera takes the viewers to a campaign headquarters with red and white colours and signs and slogans that appear to be inconsistent with the world that Travis observes from his taxi. Travis sees the world as inherently diseased and is on a mission to root out violence, disease and decadence. He becomes infatuated with Betsy, a campaign worker played by Cybill Shepherd. Point of view via mise-en-scene is displayed through scenes in which Travis’s point of view and his disconnect and social isolation comes across. For example, in an attempt to connect with Betsy, Travis gets it right the first time when he has coffee with her. On his next date with Betsy, he takes her to a seedy, sexual film. Betsy is no doubt offended by this effort at connection. By taking this approach, the viewer is drawn into and observes the distorted mind of Travis at work. Camera movements and mise-en-scene functio n to highlight Travis’s distorted mind and subjective point of view. For example, the camera picks up views of New York City that demonstrate just how Travis sees the world around him. A camera shot from inside Travis’s taxi picks up drug addicts and prostitutes. This is the world that Travis sees and is distracted by. He does not see beyond these images and forms his opinion of the outside world accordingly. The camera, by showing a view outside the taxi that selects drug addicts and prostitutes takes the viewer into the disturbed mind of Travis. This is world that Travis sees and is fixated on. A world diseased and decaying and in need of cleansing. Mise-en-scene is also used to demonstrate contradictions. The camera depicts a seemingly ordinary man, dressed neatly and appearing to be respectful and naive. Yet, the camera follows and depicts Travis visiting seedy theatres and writing letters to his parents that reveal that Travis would like to live an ordinary life, but is trapped by his perceptions of a diseased world. In his letters to his parents, Travis unrealistically himself as a working man on the verge of marrying a respectable woman (Betsy) when it is well known by the time of writing, that Travis has been rejected by Betsy. Therefore, the underlying message is that there are contradictions between that which occurs in Travis’s mind and the world in which he actually lives. The contradictions are reaching a fever pitch and this is

Pressure Canning Green Beans Assignment Example | Topics and Well Written Essays - 750 words

Pressure Canning Green Beans - Assignment Example Pressure Canning Green Beans To pressure can, one should gather the canning supplies that include the pressure canner, canning jars, canning funnel, jar lifter, canning seals and rings, a large pot or blancher, towels and dish cloths, bowls, sharp knife and large spoons. The ingredients needed will include green beans and canning salt, which is optional (Rombauer 37). Snapping the green beans involves breaking off the ends and breaking the remaining one into pieces. Snapping is not necessary do but it is preferable because it helps the beans to fit into the jar properly. The preferable size is 2 inches. One could pack the green beans either hot or cold depending on desirability. A cold pack can also be referred to as raw pack. Cold packing is quicker because it does not require heating of the green beans. In addition, in places of high altitude, cold packing is essential because it helps in achieving high pressure. The advantage with hot packing is that it allows more green beans in a jar. However, hot packing or cold packing all depends with ones choice. Both styles of packing require adding canning salt to the jar. The amount of the canning salt should be half teaspoon for pints and one teaspoon for quarts. The important point here is that canning salt is optional because it is meant for taste only (Rombauer 37). For hot packing, boil the green beans for 5 minutes before packing to the jar. One should then drain the water, pack the green beans to the jar loosely, and cover it with boiling water. One-inch headspace should be left on the jar.
