Education Opens Doors

â€Å"Education opens doors†. Do you agree? I strongly agree that education opens doors. Education provides us with the opportunity to learn new skills and to meet new people in order to share ideas and discover and develop new concepts. For people, it opens up a world of opportunities, reduces the burden of disease and poverty, and gives greater voice in society. For nations, it opens doors to economic and social prosperity, spurred by a dynamic workforce and well –informed citizenry able to compete and cooperate in the global arena.Education can be the difference between a life of grinding poverty and the potential for a full and secure one; between a child dying from preventable disease, and families raised in healthy environments; between orphans growing up in isolation, and the community having the means to protect them; between countries ripped apart by poverty and conflict, and access to secure and sustainable development. The education and skills we acquire affe ct all aspects of our lives.They have a decisive influence on our ability to find and keep a job, our capacity to take part in society, our social status and self-esteem, our family relationships and our ability to help our children through school. Better educated and more skilled people are more likely to be in work, earn more and contribute more productively to the local economy and community. Knowledge and skills provide individuals with their surest route into work and prosperity, helping to eradicate the causes of poverty and division in society.Education must also recognise that for particular minority groups other factors including discrimination, contribute to underachievement and compound its effects. Today, the value of education, in general, is highly underestimated. Education has minor as well as major purposes. However, the importance of education is quite clear. Education is the knowledge of putting one’s potentials to maximum use. A human being is not in the pr oper sense until he is educated. The importance of education is basically for two reasons. The first is that the training of a human mind is not complete without education.Education makes man ideas have background and supporting facts to whatever theories he has. We are capable of making sound decisions when we have resourceful information. When you are exposed to different ways of thinking and other perspectives, you are more likely to make a decision based on some forethought. And the second is that only through the attainment of education, are we enabled to receive information from the external world; to acquaint us with past history and receive all necessary information regarding the present.Without education, it is as though we are in a closed room with just one window to look out of and one door. Education is a great tool for our self enhancement. It gives us a sneak peek at the cultures and values of the world. Subjects like history, politics, religion and humanities can make s us much more accommodating, sympathetic to other cultures, race and religion resulting in a better bond among international communities.By learning about others values make us able to perform at our best latter in our life contributing to sound political, business related or economic decisions; it also gives us the readiness to work internationally or even locally in a diverse work force. Math and science classes give us the more than just a few basic skills to run the accounting of our life. Math and its deeper studies can help us to becoming good engineers, architects or accountants. Science and its deeper studies can lead us to contribute to the advancement of technology in the new millennium.In conclusion, education fills up the empty ignorant minds to bring about positive changes, which affect individuals, society, nations and then the world as a whole. Until we learn we don't know the benefit of learning; until we achieve knowledge we don't realize how ignorant we were. The world without education would be a world full of disorder. Therefore, to be successful in this life we must carry on the pursuit of enhancing our skills and knowledge through the virtue of education. That is why I want to study medicine in order for me to have a better future and more opened doors.

Canadian cultural Essay

In her article â€Å"I Am Half-Canadian,† Pamela Swanigan seeks to define Canadian cultural identity by comparing and contrasting it to the often highly regarded identity attributed to Americans. Born in the USA to parents of mixed racial origin and later immigrating to Canada, Swanigan offers a unique view on many of the common fallacies that come up when one envisions the culture of the United States. Contrary to the popular view, that depicts the United States as an all-welcoming â€Å"melting pot† of cultures and races, Swanigan contests instead that American culture is one of constricting self-definition and pigeonholing. She argues that American culture is neither open nor accepting of diversity, instead forcing people to strictly classify themselves into certain racial and linguistic categories- â€Å"everyone’s forced to pick one definition and stick to it. † Having personally experienced this phenomenon, as a woman of mixed race working in a traditionally male field (sports writing), Swanigan is extremely influential in presenting her case, offering a number of examples as to how Americans are boxed in to certain classifications and social expectations. She further goes on to remark on the close-minded nature of such a view, which leads many Americans to be suspicious and vaguely threatening- a stance that directly contradicts the traditional view of the United States as an open and accepting country. Swanigan contrasts this with the relatively fluid and undistinguishable collective culture of Canada, where a lack of strict individual definition leads to the misconception that Canadians have no culture at all. Instead the author seeks to dispel this myth by suggesting that this lack of identification is in fact the ideal that America claims to promote, which its neighbor to the north that has achieved.

Fish Anatomy

FISHERIES BIOLOGY AND MANAGEMENT External Fish Anatomy The following illustration of a largemouth bass shows some of the common external features that are used to describe the differences among fish species. Fish are animals that are cold-blooded, have fins and a backbone. Most fish have scales and breathe with gills. There are about 22,000 species of fish that began evolving around 480 million years ago. The largemouth billustrated abovethe typical torplike (fusiform) shape associated with many fishes used by the fish to maintain its position, move, steer and stop.They are either single fins alonthe centerline of the fish, such as the dorsal (back) fins, caudal (tail) fin and anal fin, or paired fins, which include the pectoral (chest) and pelvic (hip) fins. Fishes such as catfish have another fleshy lobe behind the dorsal fin, called an adipose (fat) fin that is not illustrated here. The dorsal and anal fins primarily help fish to not roll over onto their sides. The caudal fin is t he main fin for propulsion to move the fish forward. The paired fins assist with steering, stoppingand hovering.Scales in most bony fishes (most freshwater fishes other than gar that have ganoid scales, and catfish which have no scales) are either ctenoid or cycloid. Ctenoid scales have jagged edges and cycloid have smooth rounded edges. Ctenii are tiny, comblike projections on the exposed (posterior) edge of ctenoid scales. Bass and most other fish with spines have ctenoid scales composed of connective tissue covered with calcium. Most fishes also have a very important mucus layer covering the body that helps prevent infection.Anglers should be careful not to rub this â€Å"slime† off when handling a fish that is to be released. Maryland Envirothon 1 In many freshwater fishes the fins are supported by spines that are rigid and may be quite sharp thus playing a defensive role. Catfish have notably hard sharp fins that anglers should be wary of. The soft dorsal and caudal fins are composed of rays, as are portions of other fins. Rays are less rigid and frequently branched. The gills are the breathing apparatus of fish and are highly vascularized giving them their bright red cover.An operculum (gill cover) that is a flexible bony plate protects the sensitive gills. Water is â€Å"inhaled† through the mouth, passes over the gills and â€Å"exhaled† from beneath the operculum. Fish see through their eyes and can detect color. The eyes are rounder in fish than mammals because of the refractive index of water and focus is achieved by mthe lens in and out, not distorting it as in mammals. water and can be quite sensitive.

Some are primmostly other fish). The imported grass carp is one of the few large fishes that are prim arily herbivorous (eating plants). Fish may or may not have teeth depending on the species. Fishchain pickerel and gar have obvious canine-shaped teeth. Other fish have less obvious teeth, such as the cardiform teeth in catfish which feel like a roughened area at the front of the mouthor vomerine teeth that are tiny patches of teeth, for example, in the roof of a striped bass' mouth.Grass carp and other minnows have pharyngeal teeth modified from their gill arches for grinding that are located in the throat. that are open to the water through a series of pores (creating a line along the side of the fish).

Maryland Envirothon 5 This type of movement is quite clearly seen in the freshwater eel. Because movement of the head back and forth exerts drag, which consumes additional energy and slows travel, a great many fishes have modified this snakelike motion by keeping the waves very small along most of thelength of the body, in some cases showing no obvious movement at all, and then increasing them sharply in the tail region.It is the end of the traveling waves that moves the tail forcefully b ackand forth, providing the main propulsion for forward motion. A simpler form of tail propulsion seen in such inflexible-bodied fishes as the trunkfish, which simply alternates contractions of all the muscle blocks on one side of the body with those on the other side, causing the tail to move from side to side like a sculling paddle. Some of the predatory bony fishes are the fastest swimmers; they can cruise at speeds that are between three and six times their body lele0. 8 km/hr (0. mph), swim very slowly; others, such as the salmon, which may reach a sustainespeed of 13 km/hr (8 mph), move much faster; and it has been estimated that tuna may reach speeds of 80 km/hr (50 mph), and swordfish, 97 km/hr (60 mph).

This figure shows the growth rings of a sagittal otolith section viewed under reflective light. The darker area or â€Å"translucent zone† represents a period of fast growth. The whiter area or â€Å"opaquezone† represents a period of slower growth. The age of the fish is estimated by counting the annuli, or opaque bands, of the thin sections, as one would count rings on a tree to determine its age. Maryland Envirothon 6 Before age data can be used, the method of estimating age by counting annuli must be validated for each species to which it is applied.There are several ways to validate age, or prove that â€Å"one annulus is equal to one year. † Most obvious might be to simply rear fish from spawn, sacrifice the fish after a few years, and compare the number of rings to the known age of tho se fish. This process can be time consuming and expensive. It also creates the possibility of abnormal growth patterns caused by laboratory settings (Campana, 2001). Although this method may not be practical for validating annular ring formation, a similar method is effective in validating daily ring formation (Campana and Neilson, 1985).To avoid the effects of long-term laboratory exposure, tag and release of wild fish can be useful in validating annulus deposition. This figure shows the fluorescent tag of a common snook otolith. A captured common snook was injected with oxytetracycline (OTC), a chemical that is incorporated into calcium-rich structures including otoliths. The fish was then tagged and released. Seven years later, the fish was recaptured, sacrificed, and processed for aging. The OTC, which binds to the calcium in the otolith, appears as a glowing band when the otolith is viewed using fluorescence microscopy.The number of annuli between capture and recapture is also seven. Information like this is key to linking a single annulus to one year of growth, but such information relies heavily on time and chance. The age data gathered from otolith examinations allow scientists to model growth rates, maximum age, age at maturity, and the trend of future generations.

Health economics, market structures, government interventions Assignment

Health economics, market structures, government interventions - Assignment Example MONOPOLISTIC: Share the feature of monopoly and perfect competition. Similar purpose products are differentiated by many firms operating in market. Low entry and exit barriers welcomes new participants with high profits in short run. Participants gain profits various innovations in products. OLIGOPOLY: Market is based on few dominant firms offering similar but high level of differentiated products with innovation. Firms with dominance create barrier to entry exist with extensive control over price. Despite control of firms, prices are dependent on peer firms’ decision in market. MONOPOLY: Only one firm provides goods and services. Least differentiated product but control over price is enjoyed by the firm. Industry has high level of barrier to enter and exit from market. Profits are enjoyed by firm with constantly increasing economies of scale. ANSWER #2 The monopolistic competition is a type of competition that share features of two extreme types of competition being perfect c ompetition and monopoly. Many firms are present like perfect competition while products are differentiated like monopoly form of market structures such as movies etc. In short run monopolistic industry gets attractive by offering positive profits to participant firms and new firms enter to the market in long run. It is also due to due to no to low barrier of entry and exit in the market like perfect competition. Prices continue to increase over marginal cost in similar fashion as in case of monopoly competition. Profit maximization in monopolistically competitive market requires marginal revenue to equate marginal cost while downward slope of the demand curve takes marginal revenue lower than price. Also entry of new firm results in increased supply of differentiated products resulting in shift in the demand curve. Sharing the feature of perfect competition, price is determined at point equal to average total cost. This price is similar point where demand curve is tangent to average total cost. At this point industry offers zero economic profits and hence does not attract new participants due to zero economic profits (Gartner, 2009). ANSWER #3 Public goods are defined as set of goods having following two distinct characteristics of non-excludability and non-rival consumption. Non-excludability feature refers to the fact that usage or benefit of public goods gained by certain peoples does not result in prevention of its benefits offered to others. Non-rival consumption features of public goods refer that irrespective of consumption of public goods by certain people availability of amount or level of benefit to others is not reduced. These feature contrast public goods from the private goods. The example of public goods includes services of disaster management cells managed by government, roads and street lights etc. The feature of non- excludability results in facilitation of products to all even those who bear no financial cost. All financial cost bearers and non-bearers enjoy equal benefit of public goods irrespective of tastes and preferences and diminishing value. Such facilitation results in free-riders problem in economy. People gains confidence of availability of the goods even without paying for and hence tend to adopt trend of not paying for such services. This trend presses the increased burden on payer of such facilities. Such features of publi

Air Transport Management and Operations Essay Example | Topics and Well Written Essays - 3000 words

Air Transport Management and Operations - Essay Example The different entities in the air traffic are coordinated through a flight schedule, which often comprises of flight legs between airport locations. In addition, the flight schedule itself defines three other layers of schedules, for example, the aircraft schedule, the crew schedule, and passenger itineraries (Sheehan, 2003). Airport management contributes to the industry’s goals indirectly by directing the efforts of all the employees. This is done by the manager in charge of the airport. In addition, management involves planning, organizing, actuating and controlling, performed so as to determine and achieve objectives by the use of the employees. Managers in the airport industry must think of their actions in advance before implementing them as they can either lead to losses or benefits. Airport operations of controlling different runways and different aircrafts, as well as the safety of the passengers, require some plan rather than impromptu decisions (Tripathi, 2008). Organizing as a major function of the manager requires the coordination of human as well as material resources in the airport. Further, actuating means that the manager should engage in those activities that are aimed at motivating and directing the employees; while controlling means that; managers should try to ensure that there is no deviation from norm or plan. Whenever there is something wrong in the airport, such as economic problems, security threats, and weather disruptions, the managers must take action to remedy the situation. Managers are also required to use the employees and other resources such as finance, and equipments to attain the goals of the industry. For example, a manager who wants to increase the sales in the airport industry should try not only to motivate the employees but also to provide to increase the advertising budget. Advertising will ensure that consumers are made aware of the quality of

Factors leading to the collapse of Northern Rock and their current Dissertation

Factors leading to the collapse of Northern Rock and their current position - Dissertation Example After that it started to adapt aggressive steps in order to move high. The slowdown in the housing price inflation and an increase in the interest rate, Northern Rock issued warning regarding the profit of the bank. Soon the liquidity of the bank started to dry up and eventually pushed it towards collapse. The study tries to find out the factors that are responsible for the collapse of such a huge bank that was showing good business. At the same time it also focuses on the present condition of the bank. Table of Contents Abstract 2 Table of Contents 3 Chapter 1: Introduction 4 Chapter 2: Collapse of Northern Rock 5 Before Collapse 5 Reasons behind its collapse 7 Current Position 11 Chapter 3: Conclusion 12 REFERENCES 14 Chapter 1: Introduction The subprime mortgage financial crisis caused a steep rise in the subprime mortgage market of United States that started in the fall of year 2006 and became the cause of global financial crisis on July 2007. The newly-popular adjustable rate mo rtgages suffered an increase in the monthly payment due to the rising interest rates. Moreover the demise of the housing bubble caused the value of the property to suffer major decline leaving the house owners unable to meet their financial commitment and the leaders without any means of their losses. This financial crisis resulted into severe credit crunch, intimidating the solvency of many marginal banks and other financial institutions (Jansen, Beulig and Linsmann, 2010). Northern Rock was one of such banks that were severely hit by the waves of financial crisis. Among the entire spill over effects of the subprime crisis in US, the collapse of Northern Rock was the first in UK and was considered to be the most visible and perturbing for the authority of UK. This collapse exposed the tension that the central banks need to take some more stringent steps in order to enhance the liquidity support facilities. It also highlighted on the inherent difficulties that lay with the tripartite arrangements made to deal with the banking crisis, the deficiencies in the banking supervision and regulation in UK and the flaws evident in the deposit protection arrangement of UK (Hall, 2008). It also revealed the fragility of the banking system of UK, by shaking the complacency of the regulators, politicians and bankers, undermining the confidence of the general public on the banking system of UK and creating a calamitous effect on the economy of UK.
