My personal practicum experience took place at St Elizabeth’s Hospital, which is a small 90 bed community hospital located in Gonzales, La. St Elizabeth’s Hospital is a part of the Franciscan Missionaries of Our Lady Health System which was organized in 1984 to unite with three existing hospitals in Louisiana which were already a part of the system†¦show more content†¦The RRT intervenes before a crisis, which the Code 100 will be to activate the RRT, as a result lives are saved and adverse events are prevented. Data collection from the initiative has proven to be a beneficial tool; it has decreased code blue calls and has produced positive outcomes (Rankins, 2006). The IHI initiative included clinicians in collaboration with hospital and nurse leads to implement best practice protocols to prevent unnecessary deaths. The RRT deployed at first sign of patient decline does save lives (Richard, 2005). Objectives Code 100 implementation will prevent avoidable inpat ient deaths that are not an expected or outcome of a patient’s hospital stay (MHA, 2012). Code 100 which is the first section of a larger project that will require the staff nurses to document whenever they care a physician especially during the day shift and document all the signs and symptoms the patients’ exhibit and the intervention performed. The nurses will have a form to complete and the data will be collected to track the number of incidents and the outcome. The facility will put in place a Rapid Response Team in the coming weeks which will be activated when a nurse on the floor observe signs of deterioration from a patient to prevent the declination of the patient’s status.

Comparing poems Essay Example For Students

Comparing poems Essay The poem Presents from my aunts in Pakistan is about a half English, half Pakistani Girl who was born in Pakistan and brought up in England. Her Aunts in Pakistan sent her some traditional Pakistani clothes. In private she loves the clothes but she doest what to show her friends because she thinks that her friend wont like them.  The poets thoughts and feelings change throughout the poem. In lines 1-19 the girl is happy and grateful glistening like an orange split open (line 4) this is an optimistic image, the presents seem to be exhilarating, stunning and full of assurance. In lines 20-26 the girl feels she cant wear these clothes because she is half-English, unlike Aunt Jamila.(Lines 25 and 26). Lines 27-38 show two sides to her. One side by her saying I wanted my parents camel skin lamp. (Line 27) where she is attracted to but at the same time repelled from to consider the cruelty (line 29) but then in line 32 back to attracted to the lamp to marvel at the colours (line 32).  Lines 40-44 is about her in her bed room trying to show off her clothes but her friend isnt impressed asked to see my weekend clothes. (Line 42-43)  Lines 50-end are meant to be about the girl searching from somewhere she belongs And I was there with no fixed nationality she doesnt believe that she belongs to any fixed nationality. Staring through the fret work (line 68) she is too far away from the re-establishing Pakistan. There seems to be no set structural form to this poem. The stanzas are split up in which ever way the poet feels like in broken rhythm. The poem is written in free verse so there is no rhyme.  The use of similes and metaphors are mostly used in lines (lines 1-39) where the content is describing how beautiful the clothes are. The poet uses colours and fruit to enforce a mood across to the reader of the poem.  I liked this poem because of the way she used colours and fruit to show the way in which the girl in the poem is feeling. I also liked how she describes the all the clothes. Charlotte ONeils Song  The poem Charlotte ONeils Song is about a girl who is a servant in a mansion. She talks about her life scrubbedscrappedwashed and how she is getting bored of doing everything. The girl Charlotte ONeil, according to ships records, is a 17-year-old girl sailing to New Zealand to be a general servant in a rich mans home.  At the end she says I wont be there anymore. and it seems she slams the door and shes gone.  The mood of this poem is quite anger at the beginning and tired of doing the same job day in day out and at the end she glad she gone but know youre on your own my dear. The structure to this poem is not set up in stanzas with set syllables and number of lines. The rhyme starts of steady but the further you go into the poem the angrier she gets and the more lose the rhymes scheme goes. There are no similies or metaphors because charlotte is trying to keep you focused on what shes saying so you wont be distracted by the comparisons making what she has gone through less graphic.  I like this poem because there are no adjectives in the poem so it looks a little bare in places but she keeps it tighter by increasing the anger and letting the rhyme scheme slip to show this. I also liked the way in which she concluded the piece by saying and you can open your own front door.  Nothings changed  This poem is about the apartheid in district six, Cape Town, Africa. A man is walking through the field the fields just out side of dictrict six. He then walks into district six no board says it is, but my feet know he walks up to a white s only Inn and says theres a guard at the gatepost to hold the true Africans out. .ub8501c962e615083cf19e8c7356dab35 , .ub8501c962e615083cf19e8c7356dab35 .postImageUrl , .ub8501c962e615083cf19e8c7356dab35 .centered-text-area { min-height: 80px; position: relative; } .ub8501c962e615083cf19e8c7356dab35 , .ub8501c962e615083cf19e8c7356dab35:hover , .ub8501c962e615083cf19e8c7356dab35:visited , .ub8501c962e615083cf19e8c7356dab35:active { border:0!important; } .ub8501c962e615083cf19e8c7356dab35 .clearfix:after { content: ""; display: table; clear: both; } .ub8501c962e615083cf19e8c7356dab35 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ub8501c962e615083cf19e8c7356dab35:active , .ub8501c962e615083cf19e8c7356dab35:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ub8501c962e615083cf19e8c7356dab35 .centered-text-area { width: 100%; position: relative ; } .ub8501c962e615083cf19e8c7356dab35 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ub8501c962e615083cf19e8c7356dab35 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ub8501c962e615083cf19e8c7356dab35 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ub8501c962e615083cf19e8c7356dab35:hover .ctaButton { background-color: #34495E!important; } .ub8501c962e615083cf19e8c7356dab35 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ub8501c962e615083cf19e8c7356dab35 .ub8501c962e615083cf19e8c7356dab35-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ub8501c962e615083cf19e8c7356dab35:after { content: ""; display: block; clear: both; } READ: Rhoda"s Diary The Withered Arm by Thomas Hardy EssayThe second half of the poem is describes the way hes feeling about the whites that are better than him .he walks up to the window and without out looking already knows what hes going to see. Before I see them, there will be crush ice white glass then he takes us down the street to working mans he backs away from the window and has a burning desire to smash the clear panes in any way which he can.  The poet feeling and thoughts develop as the significantly during the course of the poem.

He then walks down into district six and his anger begins to be revealed. Talks about his hands, bones, lungs and hot, white inwards turning anger of my eyes. This surggests that he is beginning he is angry a bit but as the poem progresses the anger enhances with it.  The three poems are about different cultures. I liked the nothings changed poem because it has the most effect on me. The way in which the poet unravels the plot gradually shows how much nothing has changed.

The Interesting Narrative of Olaudah free essay sample

I believe that it sets the tone for his account, describes his attitude toward the book and gives an overall impression of Quinoa himself. It shows his work is not meant merely for entertainment but for the purpose of promoting the inhumanity and torments of slavery. 2) a. What Quinoa is saying is that the slave traders were so greedy that they didnt think about the long term just about the short term. In this case, what that means is that they packed too any slaves into the ships because they wanted to make as much money as possible.Because they did this, the living conditions for the slaves were terrible and many of them became sick. This was improvident because it didnt really take into account how much money the slave traders would lose by having the slaves be in bad condition when the time came to sell them,or how much theyd lose by having slaves die along the way.

The white crew viewed the black slaves are a source of money, not as human beings. C. The treatment of the slaves reveals that the captors do not value all human fife equally.They feel it is okay for some humans to be bought and sold like property. 3) a. Quinoa was very young and this caused him to think many of the things that happened on the voyage as magic. B. Slaves felt that their masters treated them unkindly, but there was not much to do to improve their situation as a slave. Realizing this, I think Quinoa would have been thankful for what he had had and would appreciate it. 4) a. Some slaves jumped overboard to escape the ship. Unfortunately for them, the slave hunters sailed in shark infested waters, so this only brought upon their death. They were flogged because they were meant to go down with the ship, not escape themselves. 5) Quinoa traveled to London and became involved in the abolitionist movement. The movement had been particularly strong amongst Quakers, but was by then non-denominational. Quinoa was Methodist, having been influenced by George Whitefishs evangelism in the New World. 6) It is important for them to record their experiences so that others will have a better understand of what theyre going through and will be more motivated to help change things.

Relationship between Canada and the US essays

Relationship between Canada and the US essays Relationship between Canada and the US from 1960-1963 As the last years of Diefenbaker as Prime Minister came to an end, the relation between Canada and the US reached an all time low. As the Cold War deepened, the tension between the two countries worsened. It didnt help at all when it came to the personal relationship between Prime Minister Diefenbaker and President Kennedy. Diefenbaker refused to load nuclear warheads on the missiles he had bought; therefore the relations became tenser for the two countries. Also before Diefenbaker was out of office, the Canadian government postponed placing Canadian air forces in NORAD on highest alert as the Americans, and refused to send troops there during the Cuban Missile When John F. Kennedy became president, Diefenbaker quickly started to dislike him. Not only because he was young, charming, and aggressive in pursuing American interests, but also because Kennedy urged Canada to join the Organization of American States during his visit to Ottawa in 1961, even after Diefenbaker had put down the idea. Diefenbaker was angered because Canada was always being pushed in certain areas by the US. He believed in nationalism, which meant standing firm against American When Diefenbaker was elected, he had agreed to unite the air-defense plan with the United States. But everyone in power knew that its costs would have been very 2 high, that there were no foreign orders, and that it was disorganized. As a result Canada was better off without it. Therefore Diefenbaker rejected to load nuclear warheads on the missiles that he had bought. In the later years the Cabinet split over the issue of nuclear ...

Cancer and Reproducibility of Decisions

Cancer and Reproducibility of Decisions Ur ologic ca n cer : W h a t a bo u t re p r odu c ib i l i ty of d ec i s ion m a de a t m ultidi sci plin a r y t e a m m a n a g e m e nt? BAYOUD Y, LOOCK PY, MENARD J, MESSAOUDI R, RIPERT T, PIERREVELCIN J, KOZAL S, LEON P, KAMDOUM M, CHOLET I, LARRE S . Â   Abstract: I nt r odu c t i on : The prostate cancer (PCa) treatment is multimodal. Thus multidisciplinary team management (MDTM) decision-making process appears as a tool to answer all aspects of PCa. To evaluate the reproducibility of therapeutic decisions made at MDTM. M a t erials a n d M e thod s : We compared therapeutic decisions of PCa by presenting the same file of patient under a fake identity after 6 to 12 months from the first presentation. Forty-nine files of radical prostatectomy (RP) (28 pT2, 21 pT3) performed for clinical localized PCa were represented at MDTM which included urologist, oncologist, pathologist and radiologist. Analysis of therapeutic decisions comprised criteria as: TNM stage, Gleason score, margin status and comorbidities. The reproducibility was assessed statistically by Kappa coefficient. R es u l t s: Forty-nine file of radical prostatectomy (RP). The mean age was similar in both groups. The mean PSA was 8,32 ng/ ml (3,56-19,5) in pT2 group and 9.4ng/ml (3,8-22) in pT3 group. The margin status was positive in 25% and 47,6% respectively in pT2 and pT3 group. Decision made for pT2 group were the same in 100% case (k=1). In the group of pT3 (n=21), 33% of decision were different at second MDTM, especially for pT3b with only 29% reproducible decision (k= 0,1). Concerning pT3a, 86% of decision were reproducible (k= 0,74). Con cl u s i on : We showed a reliability and reproducibility of decision made at MDTM when guidelines are well defined. The therapeutic attitudes were less reproducible in locally advanced PCa but decision concerning those cases should be made in the setting of guidelines. K e y w o r d s : Cancer, Kappa coefficient, Prostate , multidisciplinary, Reproducibility. INTRODUCTION: The prostate cancer (PCa) is the most frequent cancer in men as well in Europe and USA (1). The PCa counts for 11% of all men cancers and it’s responsible for 9% of the mortality by cancer in men in Europe. In France in 2010, the incidence of PCa was 71577 cases and the related mortality of PCa at the same year was 8791 deaths which represent a 2.5% less mortality per year during last years (2). The multidisciplinary team management becomes an obligation for all oncologic fields as mentioned by the French government law: cancer program 2003-2007, this program stipulate that each new patient should benefit from MDTM decision-making process, organize the setting of MDTM and also gives tools to develop trials of research for a new diagnosis and therapeutic arsenal (3). Some urologists express some doubt about the interest of MDTM because of it’s a new burden without assigned budget while others see in the MDTM an equalit y of chance of patients, and possibility to include patients in trials and protocols. Number of European study showed the interest of MDTM and its beneficial impact on survival (4, 5). The efficiency of decisions made at MDTM is obvious but the evidence about their reproducibility remains doubtful. Through patients underwent a radical prostatectomy (RP) for localized prostate cancer (PCa) and represented identically, we evaluated a reproducibility of decision made at MDTM.

Reaction paper of Ideoligy explore in venezuela Essay

Reaction paper of Ideoligy explore in venezuela - Essay Example Given its huge oil resources Venezuela should ideally command a lot of respect internationally as a economically stable state. This however doesn’t seem to be true with the larger percentage of it’s population living below the poverty line. At the time president Chavez took over the rains around 70% of the population was below the poverty line. It was expected and hoped that this condition would change. This however did not happen largely due to the ideologies adopted by the government. The gap between the rich and the poor is just too big considering the massive capabilities that the country has. The very thing that should generate prosperity seems to be driving the disparity. Oil should be good for any given country but when combined with corruption which is rampant in the country then the effects can be catastrophic as they are in this country. The oil industry is controlled by the rich and affluent political class. This class is well known for the greed with which they want to line their pockets with more wealth. They rarely consider the poor. The oil industry is very labour intensive which contributes for the high unemployment rates. Another factor that fuels this state is the fact that the country for the most part is dependent on imports which has never made it easy for any economy. Add to this the fact that every citizen is always trying to enrich themselves. Hoarding of these imported goods is rampart driving inflation in the country high (Dunaway 55). The high prices cause the government to try and rectify this and the most popular way for them is to make more money fuelling inflation. This inflation seems the poorer even poorer. One would argue that the best way to cure this would for a total overhaul the ideologies prevalent in the political class. Them being the main stakeholders in both the economy and the social level they are the ones who would drive any change in the country, ideological or otherwise. They need to

Organisation Analysis and Design Case Study Example | Topics and Well Written Essays - 2000 words

Organisation Analysis and Design - Case Study Example ALCAN Management made significant improvements in terms of teamwork, employee involvement and development of cooperative relations with trade unions. However, it is clear from a claim made by a maintenance engineer that they were â€Å"treated like shit† that ALCAN was treating people as â€Å"means† as â€Å"categories of status and function rather than as individuals†. This behavior had the consequence of destroying the meaning of work itself, failing to recognize and utilize properly the organization’s most valuable resource. Organizations, and ALCAN was no exception, have paid dearly for these attitudes in the various forms of worker resistance, absenteeism and complacency. 1.1 Organizational Structure Because Machine Bureaucracies are structures ridden with conflict, control systems are required to contain it. The magnified divisions of labor, horizontal and vertical, the strong departmental differentiation, the rigid distinction between line and staff, the motivational problems arising from the routine work of the operating core permeated the structure with conflict. The machine bureaucracy is typically found in the mature organization, large enough to have the volume of operating work needed for repetition and standardization and old enough to have been able to settle on the standards it wishes to use (Mintzberg, 1997;p120).

Credit Protection and Identity Theft Essay Example for Free

Credit Protection and Identity Theft Essay If you find errors on your credit report, what steps would you take to correct them? Steps we can take include writing to the credit reporting company describing what we feel is inaccurate on our credit. If we do this the agency must investigate the claim. After the investigation is complete they will send us written results with a copy of our credit report if any changes had been made. Another way we can try and correct information is by contacting and disputing any information directly with the lender. If a lender does not resolve our problem then we can request that the lender attach a statement about the dispute for every time they report the credit agency. There are many organizations that claim they will repair your credit for a fee. From your readings, should someone use a credit repair service? Why or why not? What are some actions these organizations can take that should be a red flag? Have you, a family member, or a friend been a victim of identity theft? How did it happen? Describe the resolution process- ex. how much time did it take, what credit damage was corrected? I have never been a victim of identity theft nor do I know anybody who has. From what I have read the resolution process can be long and painful mentally and physically. It could also take a very long time as in years if not caught in time. We would have to contact lenders and close out and dispute anything that was not of our knowledge. I believe then an investigation will start and if the person is ever caught then they can begin on recovering your credit and removing whatever credit was used without your knowledge. Any credit we knowingly used is still our responsibility to repay. Using the FTC site, what can you do to minimize the chance of your identity getting stolen? According to the website we should keep record of our account numbers and phone numbers to contact the lender in case we feel fraud or an inaccuracy has occurred. We should shred any receipts and documents that contain important information that we plan on throwing away. A smart thing to do would be to carry some cards separate from our wallet in case our wallet gets lost. We should check our bills often and compare receipts to our statements to make sure they match and no errors occur. If we move we need to notify the lender of this so someone else doesnt get our mail and can possibly steal any sensitive information contained in the bill.

Matrix 1 v.s. Matrix 3 :: essays research papers

After watching â€Å"Matrix Revolutions,† I was disapointed. The movie lost its confusing yet interesting story line that the first one did very well, and there were so many characters that a lot of them got lost in the story and they wasted many good actors.   Ã‚  Ã‚  Ã‚  Ã‚  When they return to the real world and the battle of the machines starts, it just goes on and on and on while Neo and Trinity disapear for a long time. The fight scenes just never cut away for such a long time that in the end it became anoying to watch. When the human base was under attack by the machines, there was no dialogue for such a long time. The effects were really good but they didn't cut away from this specific scene for what seems to be half the movie. The visual effects were just as good as the first movie but the fight scenes didn't match the originals. It isn't a really bad thing to take out the fight scenes, it's just the fact that the first movie was based solely on those fight scenes and it wasn't smart for them to take so much of them out. There were only a few good fight scenes and the biggest one dealt with flying and it was sort of overkill by the end. I think that one big thing that made â€Å"Revolutions† worse than the first movie wa s that everyone seemed to be in love with eachother. After watching the first one I was expecting more fighting but instead they turned it into romance and it was drawn out way too long. It seemed that in â€Å"Matrix Revolutions,† they had too many plot points that I've seen in other movies before.   Ã‚  Ã‚  Ã‚  Ã‚  The whole movie is full of little errors like this. For example, the machines make a deal in the end with Neo to defeat the agent Smith, and after he does, the machines are supposed to not continue attacking humans and growing them in their fields after years of doing so, just because of a promise. It doesn't make much sense. Neo comes in and saves the day at the end, but the movie doesn't really even explain how it works. Neo's about to lose and die and then magically he wins. I didn't think it was a very good ending, they should have finished the series at the end of the second movie.

Jean Kilbourne’s article “Jesus is a brand of jeans” Essay

The thesis of Jean Kilbourne’s article â€Å"Jesus is a brand of jeans† is that everything in the world is just a stuff to be consumed or to be used to sell people something, and changes peoples’ outlook. Relationships, for example, are used to sell people jewelries for their loved ones. Other advertisements take advantage of emotions to sell their products. Ads create a climate of cynicism. â€Å"Ad after ad portays our real lives as dull and ordinary, commitment to human beings as something to be avoided. † 2) Jean Kilbourne is addressing everyone who is also the audience of advertisements—that is, every one of us. Kilbourne used particular advertisements to prove the thesis, and quotes from expert opinions. The method is effective in proving the point but it remains to the individual reader whether to believe in such stuff or to just dismiss it as mere paranoia. 3) Jean Kilbourne has a very sound argument. With the use of examples, one could not help but think that advertisements propose a concept that material things are more valuable than humans—that peoples’ lives are dull and that their products are necessities to make life worthwhile. Part III One passage that I found interesting in the Jean Kilbourne’s article â€Å"Cutting girls down to size: The influence of the media on teenage body image† is that nearly half of the participants in a study that was conducted to determine the effects of magazines on teenage girls â€Å"reported a desire to loose weight because of an image in a magazine, but only 29% were actually overweight. † This gives a summary of what the article is all about and goes to show how stereotyping from advertisements could influence how one looks at things, even personally.

American Temperance Society

The American Temperance Society (ATS), first known as the American Society for the Promotion of Temperance, was established in Boston, Massachusetts on February 13, 1826. The organization was co-founded by two Presbyterian ministers, Dr. Justin Edwards and the better-known Lyman Beecher. * Formation of the American Temperance Society marked the beginning of the first formal national temperance movement in the US. * The Temperance Movement was an organized effort during the nineteenth and early twentieth centuries to limit or outlaw the consumption and production of alcoholic beverages in the United States. By the mid 1830s, more than 200,000 people belonged to this organization. The American Temperance Society published tracts and hired speakers to depict the negative effects of alcohol upon people. Lyman Beecher was a prominent theologian, educator and reformer in the years before the American Civil War. * Lyman Beecher was a prominent theologian, educator and reformer in the years before the American Civil War. Beecher was born in 1775, in New Haven, Connecticut. He graduated from Yale College in 1797 and was ordained in the Presbyterian Church in 1799. He became a minister in Long Island, New York. In 1810, he accepted a position as minister in Litchfield, Connecticut. He became well known for his fiery sermons against intemperance and slavery. In 1826, he resigned his position in Litchfield and accepted a new one in Boston, Massachusetts. By this point, his reputation had spread across the United States. The church in Boston had more money to pay a minister of his standing. It also had a much larger congregation. In 1830, Beecher's church caught fire. A merchant who rented some rooms in the church stored whiskey in the basement. The whiskey somehow ignited. Beecher took this as a personal affront considering the sermons he delivered in the church's sanctuary against the evils of liquor. Neal Dow, temperance reformer, born in Portland, Maine, 20 March 1804. He is of Quaker parentage, attended the Friends' academy in New Bedford, Massachusetts, and was trained in mercantile and manufacturing pursuits. He was chief engineer of the Portland fire department in 1839, and in 1851 and again in 1854 was elected mayor of the City. He became the champion of the project for the prohibition of the liquor traffic, which was first advocated y James Appleton in his report to the Maine legislature in 1837, and in various speeches while a member of that body. * Through Mr. Dow's efforts, while he was mayor, the Maine liquor law, prohibiting under severe penalties the sale of intoxicating beverages, was passed in 1851. After drafting the bill, which he called â€Å"A bill for the suppression of drinking houses and tippling shops,† he submitted it to the principal friends of temperance in the City, but they all objected to its radical character, as certain to insure its defeat. It provided for the search of places where it was suspected that liquors intended for sale were kept, for the seizure, condemnation, and confiscation of such liquors, if found; and for the punishment of the persons keeping them by fine and imprisonment. Maine Law of 1851, The law was forced into existence by the mayor of Portland, Neal S. Dow. Its passage prohibited the sale of alcohol except for medical or manufacturing purposes. By 1855, there were 12 states in the U. S who joined Maine in what became known as the â€Å"dry† states. And the states which allowed alcohol were dubbed â€Å"wet† states. – The act was very unpopular among many working class people and many immigrants. That is when opposition to the law turned deadly by June 2, 1855 in Portland, Maine. It was rumored that Neal S. Dow was keeping a vast supply of alcohol within the city while denying it to the citizens of Portland. He was then called the â€Å"Napoleon of Temperance,† and to others, an unadulterated hypocrite. The alcohol which was allowed into Portland was supposed to be used for medicinal and mechanical reasons were valued at about $1,600. It was distributed to doctors and pharmacists as authorized by the Maine law. – The Irish immigrant population of Portland, Maine was vocal critics of the Maine Law. They saw it as a thinly disguised attack on their culture based on stereotypes. The Irish community already distrusted Neal S. Dow. The Maine law that Dow sponsored had a mechanism whereby any three voters could apply for a search warrant based on suspicion of someone illegally selling liquor. † The Father of American Education†,† Horace Mann, was born in Franklin, Massachusetts, in 1796. Mann's schooling consisted only of brief and erratic periods of eight to ten weeks a year. Mann educated himself by reading ponderous volumes from the Franklin Town Library. This self education, combined with the fruits of a brief period of study with an intinerant school master, was sufficient to gain him admission to the sophomore class of Brown University in 1816†³ (4, Cremin). He went on to study law at Litchfield Law School and finally received admission to the bar in 1823 (15, Filler). In the year 1827 Mann won a seat in the state legislature and in 1833 ran for State Senate and won. Horace Mann felt that a common school would be the â€Å"great equalizer. † Poverty would most assuredly disappear as a broadened popular intelligence tapped new treasures of natural and material wealth. He felt that through education crime would decline sharply as would a host of moral vices like violence and fraud. In sum, there was no end to the social good which might be derived from a common school -In 1848 Mann resigned as Secretary of Education and went on to the U. S. House of Representatives and then took the post of President of Antioch College in 1852. He stayed at the college until his death in August 27, 1859. Two months before that he had given his own valedictory in a final address to the graduating class; † I beseech you to treasure up in your hearts these my parting words: Be ashamed to die until you have won some victory for Humanity† (27, Cremin). – Mann had won his victory as the public school soon stood as one of the characteristic features of American life – A â€Å"wellspring† of freedom and a â€Å"ladder of opportunity† for millions. William McGuffey, U. S. educator remembered chiefly for his series of elementary readers. McGuffey taught in the Ohio frontier schools and then at Miami University (1826 – 36). His elementary school series, starting with The Eclectic First Reader, was published between 1836 and 1857. Collections of didactic tales, aphorisms, and excerpts from great books, the readers reflect McGuffey's view that the proper education of young people required their introduction to a wide variety of topics and practical matters. They became standard texts in nearly all states for the next 50 years and sold more than 125 million copies. In these years McGuffey also served as president of Cincinnati College (1836 – 39) and of Ohio University, Athens (1839 – 43). He was a founder of the common school system of Ohio. In 1845 he was elected to the chair of mental and moral philosophy at the University of Virginia, Charlottesville, a position he held until his death. Noah Webster published his first dictionary of the English language in 1806, and in 1828 published the first edition of his An American Dictionary of the English Language. The work came out in 1828 in two volumes. It contained 12,000 words and from 30,000 to 40,000 definitions that had not appeared in any earlier dictionary. In 1840 the second edition, corrected and enlarged, came out, in two volumes. He completed the revision of an appendix a few days before his death, which occurred in New Haven on the 28th of May 1843. * Webster changed the spelling of many words in his dictionaries in an attempt to make them more phonetic. Many of the differences between American English and other English variants evident today originated this way. The modern convention of having only one acceptable and correct spelling for a word is due mostly to the efforts of Webster, in standardizing spelling. Prior to this, the popular sentiment toward spelling might have best been summed up by Benjamin Franklin who said that he â€Å"had no use for a man with but one spelling for a word. † * produced his own modern English translation of the Bible in 1833. Though an excellent and highly accurate translation, Webster’s Bible was not widely accepted, due to the continued popularity of the ancient King James version. It was, however, was the most significant English language translation of the scriptures to be done since the King James version of more than 200 years earlier. Mary Lyon, American educator, founder of Mt. Holyoke College, b. Buckland, Mass. She attended three academies in Massachusetts; later she taught at Ashfield, Mass. , Londonderry, N. H. , and Ipswich, Mass. Interested in promoting the higher education of women, she won the aid of several influential men and succeeded (1837) in establishing Mt.  Holyoke Female Seminary (later Mt. Holyoke College) at South Hadley, Mass. She served as principal for 12 years, directing the development of a well-rounded college program and emphasizing the principle of service to others. Emma Willard, Educator. Born Emma Hart on February 23, 1787, in Berlin, Connecticut. Emma Willard is remembered for her trailblazing efforts on behalf of women’s education. Raised by a father who, while a farmer, encouraged her to read and think for herself, she attended a local academy rom 1802 to 1804 and then began teaching. – In 1807 Emma Willard went to Middlebury, Vermont to head a female academy there. Two years later she married a local doctor named John Willard. She opened her own school, the Middlebury Female Seminary, in 1814 to provide advanced education that young women were denied by colleges. Her Address†¦ Proposing a Plan for Improving Female Education (1819) was a much admired and influential proposal to get public support for advanced education for young women. Emma Willard moved to Troy, New York, in 1821, where she opened the Troy Female Seminary. (It was renamed the Emma Willard School in 1895. ) With both boarding and day students, in some respects it was the first U. S. institution of serious learning for young women, though even it recognized that most of its graduates would be housewives, not professionals, and most of its students came from families of means. The school actually made a profit, and she also earned money from the textbooks she wrote.

Coordinating Conjunction Definition and Examples

Coordinating Conjunction Definition and Examples A coordinating conjunction is a  conjunction (such as and) that joins two similarly constructed and/or syntactically equal words, phrases, or clauses within a sentence, whether they are adjectives, adverbs, nouns, or verbs. Its also called a coordinator. The coordinating conjunctions in English are and, but, for, nor, or, so, and yet. (See the coordinating conjunction and as it functions in that list of conjunctions?) Compare their use with ​subordinating conjunctions, which join items that are not of equal weight. When joining two independent clauses to create a compound sentence, place a comma before the conjunction. When they join two verbs, for example in the case of a compound predicate, you dont use a comma before the conjunction.  Ã¢â‚¬â€¹ Independent Clauses vs. Compound Predicates Independent clauses look  like these examples below. They each have a subject and a verb, making them complete thoughts that stand on their own: She wondered when he would get home. She decided not to call. If we were to write them as one sentence, wed either need to join them with a semicolon or a comma and a coordinating conjunction like this:   She wondered when he would get home, but she decided not to call. Note that each clause keeps its own subject and verb. If theyd be joined without the comma and conjunction, theyd be a fused sentence or a comma splice.   This version of the  sentence contains a compound predicate, two verbs that share the same subject:   She wondered when he would get home but decided not to call. Theres no comma before but because there is only one subject for both verbs. She both wondered and decided. There are no longer two independent clauses. Decided not to call cant stand on its own as a sentence. Conjunctions Starting a Sentence In some cases, a coordinating conjunction may be used as a transition at the beginning of a new sentence. It can break up a static rhythm between similarly structured sentences or lead off a very short  sentence to add emphasis to that sentence in the paragraph. Theres some debate whether writers should be able to use the conjunctions in this way or whether thats a rule that shouldnt exist. Author David Crystal explains: And at the beginning of a sentence? During the 19th century, some schoolteachers took against the practice of beginning a sentence with a word like but or and, presumably because they noticed the way young children often overused them in their writing. But instead of gently weaning the children away from overuse, they banned the usage altogether! Generations of children were taught they should never begin a sentence with a conjunction. Some still are.There was never any authority behind this condemnation. It isnt one of the rules laid down by the first prescriptive grammarians. Indeed, one of those grammarians, Bishop Lowth, uses dozens of examples of sentences beginning with and. And in the 20th century, Henry Fowler, in his famous Dictionary of Modern English Usage, went so far as to call it a superstition. He was right. There are sentences starting with And that date back to Anglo-Saxon times. (The Story of English in 100 Words. St. Martins Press, 2012) Following through with the example in the previous section, it could read like this: She wondered when he would get home. But she decided not to call. Splitting up the two sentences changes their rhythm and pacing slightly, as compared with having them joined into one sentence with the conjunction between them. Starting a sentence with a conjunction isnt a convention you want to use sentence after sentence, paragraph after paragraph, but it can serve as a tool to create drama in a passage through altering its pacing and rhythm.

Google - Financial Statement Analysis Research Paper

Google - Financial Statement Analysis - Research Paper Example In September 2002, Google News was released with over 4000 news sources (google.com, 2010). Google Scholar was released a month later with Google maps quickly following in February 2005. In late 2005, the Google Reader and Analytics products were released. Adding to the list of company innovations include such popular items as Google Video, Google Docs, Google Gmail, Google Investor, Google Images, and Google Picassa (google.com, 2010). The purchase of YouTube was a major purchase in 2006 where it gave the public access to making their own videos and sharing them with other online users (google.com, 2010). Besides YouTube, the purchase of Doubleclick was a major purchase where Google attempted to further enhance and simplify how advertisements are bought and sold over the internet (edgaronline, 2010). The Android product is a new portable phone that the company recognizes as needed to compete in a mobile world that we live in. The company wishes to have mobile devices and applications as an important building block for the future (google.com, 2010). Marketing efforts have been relatively low cost for the company by use of public relations and simple customers sharing experiences to spread the word that Google offers a quick and efficient service along with useful products (edgaronline, 2010). The company’s sales and support department attempts to highlight the advantages of products like AdSense to leading companies all over the globe. Although customers sign up online for products such as AdSense, the sales team attempts to build positive working relationships and promote key product advantages to other companies (edgaronline, 2010). The current environment for Google is a highly competitive one which is always changing. The company faces potential threats from: (1) other search companies; (2) social networking companies; (3) new and emerging mobile products; and (4) specialized search and e-commerce sites (edgaronline,

Renaissance Art Essay Example | Topics and Well Written Essays - 750 words

Renaissance Art - Essay Example He had a lot of interest in science and produced pieces of unprecedented work during his time. He sold a lyre that he had fashioned to Lorenzo de Medici that was in the shape of the skull of a horse. It was supposed to be sent to Ludovico Sforza of Milan (Worldly Goods 564). Instead of giving the piece of artwork to Lorenzo de Medici to deliver it, he decided to do it by himself. He was then persuaded to remain in Milan by his host and this is where he painted the famous mural The last Supper on the wall of the monastery. (Painting of the last Supper by Leonardo da Vinci) His work of Raphael was preferred by Pope Leo X and earned him the position of court painter in France. His greatest piece of work was the painting of the Mona Lisa, which remains outstanding up to date. Michaelangelo Buonarroti at the age of 23 carved the pieta which brought him to fame instantly. This was first followed by his sculptor of King David that was equally a success. This made him become the symbol of al l the prospering artists in Florence. His ceiling paintings also remain to be one of the greatest undertakings of all time. Raphael was the leading painter of the renaissance period and is credited with painting The school of Athens that depicted an imaginary meeting of all the famous philosophers. This piece of work earned him the chance to paint for papal commissions which he did for the rest of his life (Guido 360). The last of the greatest artists of the renaissance period is Titian who distinguished himself from the other artists through the use of new techniques that imbued the bright colors with greater depth and subtlety. Conclusion The artists of the high renaissance period picked their commissions and didn’t have to wander from... The major characteristic of the artists in this period is that they searched for human emotion and realism in art through the use of the human method.The artists of the early renaissance period aimed at portraying human forms that appeared as if they had life in order to keep up with the spirit of humanism. They had realistic expressions and clothing that were proportional to the human beings. New techniques were developed by these artists to give the paintings a more three dimensional appearance. In order for them to achieve this, they had to study human and animal anatomy to come up with a more realistic presentation. The artists of the high renaissance period picked their commissions and didn’t have to wander from one city to the other in search of commissions like their predecessors. Their work was more refined and was highly demanded thus earning them many contracts. They changed the order of things as they shifted away from the traditional art and came up with their own philosophy on how things should be done. Their paintings still remain significant up to date owing to their unique nature and stylistic devices employed. They gave art a whole different humanistic approach that completely changed the manner in which artists carried out their business.

Individual Behavior in Organizations Essay Example | Topics and Well Written Essays - 500 words

Individual Behavior in Organizations - Essay Example In psychology, there are various approaches in understanding personality. These include trait approach, learning approach, biological and evolutionary approach and humanistic approach. Based on these approaches, leaders could be either born or made. From the trait approach, psychologists believe each person possesses certain trait to a given degree (Feldman 335). This means everyone has certain form of personality, but there is only variation of certain degree an individual possesses it. According to the learning approach, personality could be learned responses to the external environment (Feldman 338). In other words, personality could be learned. On the other hand, the biological and evolutionary approach is under the assumption that important components of personality are inherited, showing the importance of genetic factors in personality (Feldman 340). Under the humanistic approach, people are at the basic level good and continue to develop to higher level of functioning (Feldman 343). Each of these theories has strong remarkable point, but also some weak points that could be addressed by other theories. This explains the level of complexity found in understanding personality. Thus, in this manner, it has also been complex to understand whether leaders are born or made. Zaleznik believes organizations can develop leaders (81). For him, peer relationship exists and has important impacts on employee’s personality development. At Apple Inc., Steve Jobs created a culture of developing personality of its employees. There is a strong point of personality development as Jobs wanted to develop human resource that would be leading the innovation. As a result, Apple created a strong innovative culture. This clearly shows that personality could be influenced by the environment and those who already have strong degree of some certain personality tend to be developed or underdeveloped depending on the environmental influence. This could

Physical hazard

Physical hazard Can physical hazard really cause harm to consumer? Food hazard: A Food hazard can be defined as presence of undesirable matter in food which can cause negative effect on consuming it. There are three types of hazard in food industry: Physical, Chemical and Biological. Physical hazard is any foreign matter in food stuff which can cause injury or illness to a person consuming the product. These could be anything like bits of bone, piece of metal, packaging material, insects, etc. A physical hazard can enter into the food at any stage of the food production. The sources for these contaminants are raw materials, poorly maintained facilities and equipments, untrained employees, poor production procedure. To eliminate these hazards it is important to implement HACCP along with the Pre-requisite programmes such as good manufacturing practice, good hygiene, etc. It is considered to be quality issue and not as safety. A person consuming a food with physical hazard could be subjected to various risks. It can cause lacerations to mouth or throat. damage to teeth or gums. damage to stomach or intestine. How do they enter into foods? Physical hazards can enter into any stage of the production. Below are the listed out few examples. Metal: sources could be from machineries, hair, bits from knife, broken needles, and parts from vessels. Glass: sources can be broke bulbs, window panes, glass containers. Plastic: sources can be from packaging material, chopping boards, storage containers, gloves etc. Soil and stone: main sources can be from the field crops and also from the floors and ceiling of the factory. Classification of physical hazards: These are classified on their level of risks to the consumer. The Canadian Food Inspection Agency (CFIA) has categorized physical hazards into three: Category I Category II Category III The category I expresses high risk, category II with a moderate risk and category III with the low risk of any cases due to physical hazard. The low risk zone expresses that there are good control measures in place but minor infractions occur. The moderate risk zone results in average control measures established and inconsistencies occur. The high risk results in due to little or no control and has major infractions occur. Every food has its own levels of risk and every food stuffs have to be monitored and made sure that appropriate control measures are in place to eliminate the hazard to an acceptable limit. According to the Food and Drug Administration (FDA): Objects which are hard or sharp of size 7-25mm in length represent potential physical hazard in food. Natural hard or sharp components like shells can cause injury to consumers if they do not know that they are a natural food component. Natural hard and soft objects which are usually removed in foods but are 100% effective such as presence of bone in fish fillets. Elimination of Physical hazards: There are systems and methods to eliminate physical hazard to an acceptable limit. HACCP and pre requisite programme is very important and effective. But to focus on the point of entry of hazards would be more effective, which are raw materials, storage and specifications. Inspection of raw material and food ingredient for any contaminants Eg: stones in rice. Storage Good storage practice and evaluation of potential risks in storage area Eg: Bulbs, insects, wooden pallets, etc. Could be prevented using bulb cover, prevention of insects. Specifications and control for all ingredients and components including raw materials and packaging materials. The specifications must comply with the rules. Eg: A limit of detection should be established to avoid false detection. Installing effective detection device and eliminating physical hazards. Eg: Metal detectors, filters etc). Periodic checking and upgrade of equipments in facilities to avoid source of physical hazards such as nuts and bolts from worn out equipments. Employment training on shipping, storing and handling of food materials will also help reducing physical hazards. How can physical hazards be detected and eliminated? There are different types of methods to detect physical hazards. Metal detectors will help in detecting metals in food stuffs. They can set up to products from the production line if metal is detected. It is also essential to check the detectors frequently to be accurate. X- Ray machines can also be used on food production lines to detect hazards such as stones, plastics, bones and metals, etc. Visual inspection could also help in a few cases of physical hazards. Chicken manufacturing factory: Let us consider process of raw breast chicken factory and the physical hazards involved. The process starts by getting the raw chicken from the primary producer. This is exercised by relying on supplier quality assurance (SQA) and this guarantee the supplier is meeting the specification of the buyer and the product is safe from hazards till the time of delivering it to the buyer. The chicken is cut; the skin is removed and cleaned. At this stage, physical hazards involved are pieces from the chopping board, chipped bits of knife, bones, feathers, etc. The hazards caused by these can be prevented by having good maintenance of the equipments along with proper training for the staffs. SSOPs (Sanitation Standard operating procedures) can help very much in cleaning of the machineries and equipments. This holds all records for cleaning routines in a daily basis and is signed off by a staff stating that the machine is free from any debris from the previous routine and is working up to its l evel. This is made mandatory in Meat and poultry operations from 1997 because of the products lower threshold of getting spoilt. The chicken is then packed and stored below 4C. Packing itself has high probability for physical hazards to be introduced, for example the packaging material, the labels used etc. Packing material can be a hazard and hence visual inspection can be done to ensure the packing. A detailed example for SSOP is given below to sanitize automated labelling machine. This is done on a daily basis and weekly once for cleaning the inside parts. Removal of all debris and physical matter. Wiped by a clean cloth dipped in soap water. A thin spray of QUATS (Ammonium compound) solution is applied and made to dry. Visual inspection is done to ensure that the machine is clean. If anything is broken it is always compulsory to call maintenance team to fix it. Once a physical hazard has been detected, an effective program should be exercised immediately to eliminate these threats or bring it to an acceptable level. HACCP will help to bring down the risk to an acceptable level or clear out every physical hazard from the system. Auditing process would bring out the area of weakness in the production cycle. Make sure that the CCPs (Critical control point) are covered by the respective critical limits. All the process is to be written into a record for future use in case of emergencies. A regular auditing will help the production within safe limits and not leading to any disaster. More assistance can be obtained from consulting services, trained HACCP professionals, on-site training for workers etc. Therefore to prevent any risk of food incidents to consumers and from economic downfall, it is obvious to identify and understand the prone hazards. Make sure effective control measures are in place that would reduce or remove any hazards entry sit uation. A well developed HACCP plan will help solve most of the possible hazard situation and a well controlled quality control system will be of a good support. Taking up these steps would ensure that a food produced in a factory is safe from any possible physical hazards.

Bill Gates :: essays research papers

Bill Gates On October 28, 1955, in Seattle, Washington a boy was born. This child would grow up to be one of the most successful people in the history of man. His name, William (Bill) Henry Gates. Bill a.k.a. Trey was a different child from the beginning of his life. His first five years were normal just like most kids. Once he turned six his parents would almost go crazy. He declared war on his mother and always talked back to her as in this example; She would call him up to dinner from his basement bedroom and he would not respond. "What are you doing?" she once demanded over the intercom. "I'm thinking," he shouted back. "You're thinking?" "Yes, Mom, I'm thinking," he said fiercely. "Have you ever tried thinking?" His mother sent him to a psychologist, after a year of tests and studies the doctor came up with a solution. His answer was, "There is nothing you can do. Just give up and live with it." Bill attended Lakeside School. It was a very nice private school. There he learned how to use a computer. His friend, Paul Allen and he would start their computer programming there. The first programs they made were a math program and tic-tac- toe. Bill and three other friends joined forces to make the Lakeside Programmers Group. Bill then went out to a store, which just received a new IBM. He convinced the boss to let him and his friends use the computer. In exchange, he would have to debug the computer. Bill got so obsessed in it that he went to the store late at night and worked on the computer! A little later that year, Bill attended Harvard. To most people there he was considered a snob and idiot. He would order pizza every day and go to many bars. In 1974, Bill and Paul Allen created BASIC, a computer language. MITS then bought a license to have the product. At the age of twenty-one, Bill dropped out of Harvard to work on Microsoft all the time. Within three months, MITS ripped up the contract. Bill found a person in Japan who would help him. Bill and Paul then set up a building in Albuquerque, New Mexico. They then renamed their company Microsoft. The original name was Allen&Gates. Bill loved New Mexico. He had his favorite Porsche, which he called Sand Buggy.

The bad things about Obama’s economic plan in foreign policy

To say the economic state of America is the most pressing need on the minds of most Americans today, would certainly not be too far from the truth. This is perhaps why both candidates realize that they have to say something at least on this subject. It is sad however to note that Obama’s plans depict a gross lack of understanding of our economic travails. Indeed, a group of respected economists noted recently that â€Å"Barack Obama’s economic proposals are wrong for the American economy†. Firstly, Obama proposes an overall increase in tax rates just as he admits that this proposal would not serve a weak economy. One wonders therefore how he thinks this would work in present day America. Or is this the strong economy Obama imagines for Americans? Increased tax rates would raise federal spending, bring about a slow in economic growth and of course result in massive job losses which of course heads us for another depression which we sure do not pray for. Again, Obama intends to end America’s trade ties the world over. Now, to decide against international trade is certainly not in our best interest, at least not in these times for the economists said â€Å"international trade is also a powerful source of strength in a weak economy†. Also, more jobs are created when we export our goods abroad and cheap products are also imported for the middle class and low income earners to especially to consume. It is this set of people that Obama’s plans would deprive of this veritable source of livelihood. As part of his plans, he also wishes to withdraw American forces from Iraq so as to free funds for the local economy. But we know that can not be true when an holistic view of the costs and benefits of the war would become after such rash withdrawal. In conclusion, Obama’s plans lack depth and appear destined to fail beyond redemption if allowed to run.

Arab sheikdoms in the United Arab Emirates Essay

Dubai is one of the seven Arab sheikdoms in the United Arab Emirates (U. A. E. ). Before oil and gas were discovered in 1958, it was among the very poor sheikdoms under British protection and was once called a Trucial State. Today, their sheiks are independent and among the world’s richest men, with a gross annual income of $25. 7 billion. It has vast reserves of oil and natural gas (Ibrahim, 1982). The land is mainly salt mashes, barren desert, and sandy plain. Oases stud the desert areas. To the east, the mountains lie close to the sea. It is also famous as having the highest cost of living in the world – the cheapest apartment rents for $1,000 per month (Peck, 1986). The Emiratians (Dubai people) used to be pirates, fishermen or pearl divers, nomads or oasis farmers. Most are now wage earners or businessmen who feel more conscious of a national identity as a rich and important country. They are famous for two unique sports: (1) camel races, and (2) falconry. Colorful music, dancing and singing also give life to this otherwise dry place. This area of Gulf was notorious for piracy. They preyed on the trade between Europe and China. The British came in 1806 and started to impose oder against the Arab pirates. In 1853, piracy was finally wiped out when the sheiks signed the Perpetual Maritime Truce Agreement with Britain. Thus, the Pirate Coast became the respectable Trucial States (Seale, 1988). Today, Dubai is the largest commercial center and the nerve center for smuggling Western currency, gold, and other goods into the Indian subcontinent, especially Pakistan. Dubai is also the outlet for capital fleeing Afghanistan and Iran. One phenomenon of the oil boom was to fill Dubai’s population (like that of Kuwait and Qatar) mostly with foreigners. The majority of the population or around 50% is Indo-Pakistani outnumber the native Arabs, who populate the land by only 42%. The large foreign population (mostly migrant workers) are lured to Dubai by the high salaries, welfare benefits, and rapid development. To keep discipline, the governing Arab sheiks have emphasized Muslim (Shariah) law, religious education, and the observance of Muslim practices. The Muslim rulers and people are Sunnis, strongly influenced by the strict Wahabi sect of neighboring Saudi Arabia (Peck, 1986). Diplomacy, national security, information, communications, health, education, and the budgets of the three smaller emirates are decided by the federal government. The local sheiks retain control over policy within their emirates. The laws of Dubai (under the United Arab of Emirates) are divided into two main categories: union laws and decrees. A bill drafted by the Council of Ministers for non-binding deliberation by the Federal National Council and then submitted to the president for his assent and the Supreme Council of the Union for ratification becomes a union law when promulgated by the president. Decrees are issued jointly by the president and the Council of Ministers between sessions of the Supreme Council of the Union. As the final say is always on the Supreme Council of the Union, a decree must only be confirmed by them to remain valid (Ibrahim, 1982). Dubai’s political system, which is a unique combination of the traditional and the modern, has underpinned this political success, enabling the country to develop a modern administrative structure while, at the same time, ensuring that the best of the traditions of the past are maintained, adapted and preserved (Ibrahim, 1982). Relations with the other members of the U. A. E. have not always been smooth. The discovery of a big natural gas field in Sharjah reopened a border dispute with Dubai. In November 1982, Dubai sent tanks to the border to prevent Sharjah’s foreign contractors from drilling the field (Seale, 1988). However, not all is coming up roses for Dubai. Bad planning and extravagance have now caused new miseries. In fact, the most outstanding examples of ill-conceived investment in the Arab world are found in the Dubai ports and so-called international airports stand cheek to cheek. Within fifty kilometers of its coast are three major ports, including the Mina Jabel Ali, the biggest manmade port ever built. Its sixty-seven berths are now suffering terrible losses. Being a member of the United Arab Emirates, Dubai has an international airport of its own, making cynics joke that the state boundaries end where the next runway begins. The headquarters of the Arab Monetary Fund in Dubai have polished one-way windows done with gold compound (Peck, 1986). References Ibrahim, Saad Eddin. (1982).
