The video The End of the Line investigates the issue of over fishing Essay

The video The End of the Line investigates the issue of over fishing of fish species due to illegal catches and surpassed fishing quotas - Essay Example Eventually, the effects of overfishing would be briefly discussed before touching on the economic issues of overfishing. According to the film, commercial overfishing actually started about 50 years ago when advances in technology enabled various fishermen to increase their catch magnanimously. The conventional trawlers and small fishing boats were replaced by huge factory ships which have the capacity to freeze or tin fishes up to the time that their holds are full. Economies of scale are practiced as early as this when these huge factory ships invested the necessary funds to ensure that their catches should be maximized before they would return to the respective ports. Overfishing has debilitating effects on all marine life. As the film emphasized, it initially examined the worrisome extinction of the bluefin tuna and other big fishes due to the increasing demand for sushi. The decrease in the pool of big fishes has the repercussion of increasing the population of jellyfishes. The economic implications of an overpopulation of jellyfishes are follows: there are more losses in terms of revenues for the fishing industry; without fishes there is rampant unemployment; the jellyfishes endangers fishermen and beach goers; and the presence of jellyfishes cause a decline in the prices of the remaining fishes caught. According to Kelly (2010), â€Å"the existence of jelly fish has changed consumer preferences, concerns about the quality of fish has led to a decline in the price of fish, this has resulted as consumers demand less fish given that they fear that the fish may be contaminated with sting venom from jelly fish, therefore this has resulted into a loss of revenue for fishermen who have now decided to exit the fishing industry.† The film has warned viewers that â€Å"scientists predict that if we continue fishing as we are now, we will see the end of most seafood by 2048† (The Film, n.d. par. 8).

Slavery Northerners and Southerners Essay Example | Topics and Well Written Essays - 500 words

Slavery Northerners and Southerners - Essay Example The niggers (black people) were the ones subjected to slavery. In the long run, some of the American people realized the evil of slavery and considered it a sin. The first abolitionist movement was founded in the northern part of America. It was the northerners who first discovered the immoral aspect of slavery and called for its complete abolition. While slavery was dying in the north, the southerners demanded for more slaves. Cotton gin was invented during that time (Burns, n.d.). The device increased the production of cotton as well as the demand for slave labor. Thus, more and more black people were sold in the southern part. In this context, the southerners feared of economic loss and racial equality if slavery was to be abolished (Burns, n.d.). Southerners believed that black people are meant to work and serve the white people. As new territories and states were formed, the topic on slavery became controversial than ever. Specifically, the question of whether or not slavery was to be allowed in the newly formed states and territories caught both the northerners and southerners attention. The answer to the query was critical to their respective economic and racial concern. The question bothered the northerners since allowing slavery in the new states would be a disadvantage on their part. Stated otherwise, the legalization of slavery in those states was considered by the northerners as unfair and an economic threat.

Teacher Development Essay Example for Free

Teacher Development Essay The term â€Å"teacher development† (TD) was first coined in the 1980s. Only in the past decade has TD emerged as an identifiable area of study and ever since then much has been written on the concept of TD? teacher knowledge? teachers new role and respnosibilities. There have been many studies on the concepts of TD from many different perspectvies since 1990s. TD is a term used to describe a process of continual intellectual, experiential, and attitudinal growth of teachers. It is a ligelong growth both before and throughout a teacher’s entire career (Lange,1990;Crandall,2000;Wu Yian,2008). TD connotes continuance, it does not end when the degree is given or the certification achieved. Even superior teachers have weaknesses which should be improved. Teachers takes on different roles and responsibilities in programmes which center on TD. Teachers’ voice increasingly are being heard in literature on TD. The teacher is no longer in a subservient or subordinate role, passively awaiting guidance direction and suggestions for change and improvement. The teacher is an investigator of his or her own classroom(Richards,1989). The teacher assumes the responsibilities for inquiry into classroom practice and analysis of their experiences. The recent rise in â€Å"action research† (e. g,. Elliott, 1991; Nokffke,1989; Wu Zhongjie,1995) is the best illustration of how teachers involve them in the interpretation and representation of their teaching practice. Much research has explored the teacher knowledge and emphasized the need for constant updating of knowledge for TD. Shulman (1987) pointed out the framework of teacher knowledge: Content Knowledge(CK)? Pedagogical Knowledge(PK)? pedegogical content knowledge(PCK) and Support Knowledge(SK). Much of the work stresses the change and value of foreign language PCK: such as attitudes toward teacher control in the classroom? instructional goals for daily lessons and considerations for resopnding to student needs(Watzke, 2007). Freeman Johnson’s (1998) position that teacher knowledge should be rooted in teachers’ actual practice. They discuss the FL teachers’ concerns about how to develop their PCK through teaching practice.

Robert Goddard: The Father of Modern Rocketry Essay example -- essays

Robert Hutchings Goddard was a futurist. He was born in Worcester, Massachusetts on October 5, 1882. He was the son of a machinist and his father was known for his brilliance with machinery and tools. The Goddard’s moved from Worcester to Boston while Robert was just an infant, because his father went in half and half on a local machine tools shop. In Boston, is where the young Robert Goddard spent his youth as an only child, and most of his younger years were spent alone at home due to his mother’s illness with tuberculosis. Robert would not see his family’s hometown of Worcester again until he was seventeen in 1899. Much of his life was spent as an ill child (Spangenburg, 10), and he was an average student with an aversion to mathematics. Illness kept him out of school entirely in that autumn of 1899, and by this time Robert had only completed his freshman year of high school. Although he was unable to spend a lot of time within institutional walls, the young Goddard was not without a strong yearning to learn--at least to learn science. Much of the time he spent sick at home sick was consumed reading the Scientific American, or books from the library both science and science fiction novels—-especially H.G. Wells’ War of the Worlds, a novel he would re-examine often in later years (Burrows, 32). Robert Goddard found happiness while doing his chores and often used found this time for relaxing. Like many young seventeen year olds, the time was spent daydreaming and this was the case on the 19th day of October 1899. Little did the young man know that this entry in his diary would change his entire life: â€Å"As I looked toward the fields in the east I imagined how wonderful it would be to make some device which had even the possibility of ascending to Mars, and how it would look on a small scale if sent up from the meadow at my feet. . .It seemed to me that a weight whirling around a horizontal shaft, moving more rapidly above than below, could furnish lift by virtue of the greater centrifugal force at the top of the path. I was a different boy when I descended the tree from when I ascended, for existence at last seemed very purposive.† (Yost, 145)   Ã‚  Ã‚  Ã‚  Ã‚   This new idea was known as the linear-force-from-eccentric-rotation, and although it was only a daydream of the young man, it was the spark that would ignite Goddard’s unendin... ...f his research, the inventor was able to accomplish his goal of creating a rocket capable of flight, and his design would later reach the stars. Furthermore, had his work been sponsored by the Armed Forces after the First World War, the space race would have not been such a challenge for the United States (Yost, 144).

The Airline Industry

One of the major industries affected by the September 11 attacks had been the airline industry. Aside from security improvements were put in place as a response to the hijacking of four commercial aircraft, the industry as a whole lost a total of $42 billion from 2001 to 2005.The president of the Air Transport Association has called the current situation of the airline industry as a â€Å"perfect storm of adversity†. Two of the largest commercial carriers are currently under bankruptcy protection and two others have gone in and out of bankruptcy court in the years after 9/11.These losses could be attributed to lower passenger traffic in the wake of the terrorist attacks. The price for jet fuel has also been rising since 2001 which adds to the costs incurred by the carriers.   Jet fuel price in 2006 was up 168% from pre-2001 levels (Isidore, 2006).While the US air industry is slowing down, there has been an increase in global air passenger numbers. Most of these increases are coming from developing economies in Asia and Europe.Airlines in Asia grew at a rate of 20% annually while airlines in the middle east grew 11%. Similarly, air routes linking the US with Asia and Europe are also expected to see an increase in passengers (Shriner, 1994).Demand and Supply ElasticityWhile these changes could be directly attributed to the 2001 attacks and their repercussions, some changes in the airline industry has emanated from the industry itself. The older legacy airlines had to face numerous new entries in the form of low cost, low frills carriers.These new low cost carriers have kept the price of airlines travel low over the past few years. Passengers now had more choices and as a result, total air traffic had been increasing while average fares have not kept pace. Legacy airlines with larger operational costs could not compete with the lower fares.As a result, they had to streamline their operations by cutting excess manpower and retiring older, less fuel efficie nt aircraft in their fleets. The fleets of the legacy carriers have shrunk by 23% since 2001 and their workforce has dropped 38% during the same amount of time (Isidore, 2006).The proliferation of low cost carriers since 2001 has essentially increased the price elasticity of demand for air travel. While all airlines serve the same purpose – air travel – each airline can still be differentiated from one another.Low cost carriers may not offer the same kind of quality service found in legacy carriers. In effect, when passengers book a flight, they are choosing between goods from airline A, airline B etc. Since passengers have more choices due to the introduction of low cost carriers, their substitution between airlines has become easier.This relatively high elasticity is reflected in the increasing passenger counts at a relatively constant fare (price) schedule.Externalities of the Airline IndustryAirlines, whether legacy or low cost are now keen on improving their fuel efficiency due to the rising costs of jet fuel. Fuel costs account for 10-12% of annual airline operating costs. One way that airlines are trying to improve fuel efficiency is by retiring older aircraft with poor fuel efficiency (May, 2003).One industry that is intrinsically linked with the airline industry is the aircraft manufacturing industry. The US is a world leader in aircraft manufacturing with US aircraft manufacturers delivering 71% of new aircraft in the early years of the 1990s.Even with the boom in airline travel in the developing world, US airlines still account for roughly 25% of aircraft orders from US aircraft manufacturers like Boeing and McDonnell Douglas   (Shriner, 1994). Clearly, an increase in income by the airline industry will translate to more orders of aircraft. In that case, the airline industry exerts positive externalities on the aircraft manufacturing industry.The positive externalities do not end with increased production by US jet manufacturers. As airlines keep pushing for more fuel efficient and modern aircraft, they are providing an incentive for technology development in the aircraft sector.The increasing prices for jet fuel are even pushing this new technology development even further in the direction of making air travel more fuel efficient. An example of such technology development is in the new Boeing 787 Dreamliner aircraft which is due to enter service next year.Being made out of composite materials, it is much lighter and thus uses up 20% less fuel than similarly sized jets. An offshoot of using composite materials is a more comfortable flight experience as the cabin air does not need to be so dry (humidity causes metal to corrode) and the air pressure can be made much higher in order to make breathing easier.The use of metal precluded using higher cabin pressure as it may accelerate metal fatigue (The Economist, 2007). It is important to note that this externality does not end at Boeing. Advances that Boeing are ma king are sometimes tied to and sometimes preceded by fundamental R&D performed at universities (Shriner, 1994).We can therefore see how the airline industry promotes R&D and helps maintain the dominance of the US in aircraft technology.Even though new aircraft like the Dreamliner might reduce fuel consumption, it still does not change the fact that the airline industry has a huge externality in the form of pollution. Aviation is responsible for 2% of anthropogenic carbon dioxide production. Aircraft also release other noxious gases such as nitrogen oxides, soot and water vapor.However, the polluting effects of airlines are magnified since these gases are released directly into the upper atmosphere where they form condensation trails and cirrus clouds. The fact that air pollution from aircraft is released at a high altitude may have the effect of double the same amount of carbon dioxide released at ground level (The Economist, 2007).

Appointments For The Health Care System - 888 Words

Problem Statement Patients have been missing appointments or have canceled required follow up testing which were ordered by providers. These appointments are either canceled or no show within 24hrs before scheduled time. Missed appointments are a cost to the health care system in terms of personnel time, extended waiting lists, and the loss of potentially beneficial services. In the past quarter we have seen a decline in No Show Rate. We have 160 weekly spaces available for appointments in the hospital. The 10 % of the patients did not show up, which equals a total of 16 missed appointments a week at $120 per visit. $1,920 in lost revenue in a week which equals $23,040 in the past 3 months. Which means patients failed to receive a recommended care, and the appointment slots were wasted. Generally, no-show rates range from 5%-55% (6). Pediatric clinics might see a no-show rate of below 5%, urban family clinics often see no-show rates between 10%-20% (8). And certain outpatient and surgical clinics-colonoscopies, endoscopies, pulmonary tests and other procedures that require special prep or diets by the patient- have even higher rates, around 50% (8,11). In 2010 study shows specifically at heart failure patients has high no-show rates (3). A little survey to determine the reasons of no show in the John Adams hospitals were conducted last week.

Symptoms And Treatment Of Schizophrenia - 863 Words

The streets of many cities are homes for thousands of people with no homes, no money and seemingly no lives. When seen talking to themselves or yelling at a wall, ordinary people cross the street or simply look the other way. It never occurred to them that these â€Å"crazies† ate often very sick people with the incurable disease schizophrenia. What they don’t know also realize is that this disease could just as likely be a friend, cousin, sister, or even them. Schizophrenia was first recognized by a Belgian, Benoit A. Morel. He called it demence precoce and describes it as a condition in young people, similar to the deterioration of the old, of arrested development. Morel noted â€Å"the fact that it led to severe emotional and intellectual deterioration† (Collier’s 389). Because of the age of occurrence, the name was changed to precocious dementia, and changed again in 1911 to two Greek words: schizein(split) and phren (mind) by Swiss psychiatrist Eugen Bleuler (Collier’s 389). In 1896 and well into the 1900’s, psychologists predominantly believed in the theories of three men: German Dr. Emil Kraeplin, Dr. Sigmund Freud of Austria, and U.S. Dr. John B. Watson (Long 49). Kraeplin systematically studied the different conditions patients showed of the disease and classified them into four groups: paranoid, hebephrenic, catatonic, and simple (Collier’s 389).
