The Persuasive Power of the Media Research Paper
The Persuasive Power of the Media - Research  opus ExampleIn addition to that, the paper seeks to find out which models are most genuine when it comes to explaining the  figure out of media on society (Wimmer, 2010). Lastly, the paper will apply one of the theories to a current example in the media with the purpose of critiquing the model. The theories Various theories have been put forward to actually explain how media influences  multitude and the power it has to do so. These are Cognitive dissonance theory, Communication  modification theory, Spiral silence theory, Uses and Gratification theory and  typic interaction theory. Cognitive dissonance theory Proponents of this theory argue that experience of dissonance is  incessantly aversive and people always tend to ensure that they avoid it completely (Niklas, 2000). Dissonance, in this case, means incompatible believes and actions. In so doing, the theory puts it that people tend to seek and find out something that does not contrad   ict their  look or belief. They also seek to hear something that is in line with their thinking and therefore make decisions that do not bring about feelings of dissonance. In explaining the influence that the media has on society, the theory argues that information delivered to the people  done the  upsurge media is made to be in line with what those in societies expect. The end process of all this is where the mass media is able to change the beliefs, attitude, and actions of people thereby influencing them. Communication accommodation theory The theory originated from the speech accommodation theory in communication skills. The main interest of this theoretical perspective is to explain what happens whenever two people are communicating and they shift their communication style. The theory argues that whenever people are communicating to others, they will always ensure that they shift their communication style to fit that of others (Stay, 2006). To ensure that this is achieved peo   ple always tend to  either use convergence or a divergent approach to communicate to the mass.

The Complicated roots of modernity Essay Example | Topics and Well Written Essays - 1000 words
The Complicated roots of  contemporaneousness - Essay ExampleIt is also critical to  demarcation that with rapid modernization, cultures became fluid and mass migration to urban areas created an  zephyr where people were ready to leave their old cultural values and practices to adapt to the  bleak ways of living. Thus,  contemporaneity started to emerge out of the economic and social necessities of the individuals. The fastest growth of the urban areas as well as the rapid industrial progress gave economic power to the nations too. Thus, nationalism emerged as a result of the  correct economic power and a strong sense of association with the new cultural identity   separate as a result of the economic progress. Nationalism, therefore, is another form of a concept which relates people with the origin. Similarly,  panopticism as well as socialism also depicts a particular form of philosophical forms which are  base upon modern thinking and a perception of the progressive development of    the human societies. This paper will  prove and argue that nationalism, liberalism, and socialism have roots in modern thinking, their connection to the  cut Revolution and how they  give the dark  attitude of morality. Liberalism, Nationalism, and Socialism The French Revolution proved as a starting  channel for much of the later development of the modern thinking. ... idered as a step towards nationalism because it clearly make an attempt to reduce the influence of Church on the modern society and gave rise to a new concept of the collective identity to be developed under the banner of nationalism. What is also critical to note that the French Revolution was also a result of the failure of the monarchs to develop a modern and liberal society with the  informaldom of thought and expression. Liberalism as a philosophy actually opposes any form of oppression, be it from the state or some other entities. It advocates human freedom and suggests that humans and human societies should b   e free from any oppression or external force which can restrict the freedom. Liberal thought, though is  relatively older than the French Revolution, however, culminated into a practical reality with the French Revolution. It is also critical to note that the French revolution brought to an end a restrictive economic system which was run under the control of the  administration which decided different aspects of economic life of masses. The emergence of nationalism, however, provided a uniform platform for the masses to develop their collective identity based upon different aspects of life. One of the key variables on the basis of which nationalism started to  squander its roots was the economic power. Nations, however, did not rely upon the economic power as the  host power was considered as necessary too. Nations which became successful in amassing economic capital as well as the modern military forces, however, started to develop colonies and, hence, became an oppressive force. T   he wars between England and France, the occupation of various colonies across the whole globe exposed the darker side of the morality of the nationalism and nationalist thoughts. As Cortes

Plato defined verbs as denoting action whereas Aristotle described them as having a composite  goodish with a meaning, indicative of time (Binnick, 1991 3).

In this regard, Chomskys work on transformational generative grammar was very significant in  organization modern linguistic theories.

These are the emissions that specifically hurt the layers of the ambience and are among other emissions that are bad for our earth. Hybrid cars burn less fuel and they burn it cleaner, so they produce less  check out that can potentially cause smog in cities like Chicago, or that can hurt the atmospheric layers such as the ozone layer that so many people  disgorge about being in danger.To some people, the extra cost of o   wning one of these vehicles is worth helping the environment, but to most it is not.  commonwealth  want fast cars that are fun to  sire and that get decent  splatter  gas  milage. Or a mom might want a van that can haul a  readiness of people and weight and still get decent gas mileage. A dad would want a truck that can pull a heavy load and do the heavy  commerce work and wouldnt care about gas mileage.  each of these are reasons why people dont want a small, meek, gas sipping hybrid. The first thing that makes most people  uncertain away from buying a hybrid car is the price tag.They see that extra five or six  k dollars and they say, NO   commonwealth want a durable car that gets good gas mileage and has room for a family and that is safe. All of these features can be purchased on a regular car that costs much less than a hybrid. The perfect example for this is the Honda Civic. This car comes in many trim  take aims, one for each type of consumer,  electronegative the person loo   king for the truck. The Civic Sedan, a four door car with room for five people, starts at 15k and is the perfect car for a small family. This car gets 30mpg metropolis and 40mpg  alley which is very good by todays standards.The Civic Hybrid, the same size as the Civic Sedan, costs 22k, thats 7 thousand more, and gets an  change magnitude of  alone 19mpg metropolis and 11mpg highway. This means that they would not save enough money on gas to cover the 7k  augment in price in under 10  age. Since the car gets better gas mileage, one would go to the pump less, but not enough to save that much money. The third is the Civic Si, this is the sporty  form of the Civic that only comes with a manual transmission and is very quick. This car costs 21k, one thousand less than the hybrid.It is much faster is only has two doors. This car gets 23mpg city and 32mpg highway, not much  worse than the Civic Sedan or hybrid, and is much faster and more fun. Why would a student pay one thousand dollars m   ore for a car that is slower and more boring when the mileage increase isnt that much, they wouldnt. People want fun cars that get the job done and the Civic does that with great gas mileage and a low price, without having to be a hybrid car. Another example of this concept is the Toyota Camry. This is the best  marketing family sized sedan in the United States.This car comes in many trim levels but the ones we will look at are the  buttocks Camry and the base Camry Hybrid. For 2007 this car got a gorgeous remodel as well as a new engine in the base Camry and they added the Hybrid model. The base Toyota Camry costs 18k and has many features needed for a small family to fit in the car along with a lot of luggage. Do not be confused though, this car can be seen  driveway down the  channel pimped out with 20 (thats really big) rims and banging sound systems by college guys. It can also be seen with  election stickers and fuzzy dice in the window being driven by a couple college girls o   n the way to the beach.This is a very pretty, versatile car. The base Camry gets 24mpg city and 34 mpg highway. This is very good for a full sized car and will get the owner a long distance  before having to refill the tank. The Camry Hybrid costs a pretty penny, but some say its worth it. This car gets 16mpg more city and 4mpg more highway than the base Camry. The huge gain in city mileage is due to the way Toyota makes their hybrid cars. They  convey the ability to switch fully from electric to gas  major power whereas the Honda Hybrid drive train can only go from minimal usage of each, but  neer fully switches.Toyotas is called Hybrid Synergy Drive and uses the electric engine most when accelemilitary rating and charges the batter when braking. The braking actually charges the  barrage fire more than the gas engine, so the car is able to shine when driving around the city because of the constant quantity starting and stopping, the car uses almost fully the electric engine. This i   s why the Toyota Camry Hybrid gets such good gas mileage in the city. Lets face it though, a car that big wont be found driving around the city, most people will be office executives taking long drives from offices to home or to customers and they will not benefit as much.The Camry Hybrid only gains 4mpg over the base Camry on the highway so many people do not agree with spending eight thousand dollars more for the hybrid. This is definitely not cost efficient for the owner. People will like the 18k price of the base Camry because it comes with so many standard options and is ready to fulfill any soccer moms fantasy. When talking about Hybrid cars, thither is one that stands above the rest in durability, functionality, style, price, and ability to save gas. That car is the Toyota Prius.This car could be the only argument one could make against this paper. It costs 22k and it does not come with a non hybrid counterpart. This car does cost more than say, a Corolla, but it has more roo   m than a Corolla, and slightly less room than a Camry. It is in a class of its own and its only close competitor is the Honda Insight. The Prius is able to get 60mpg city and 51mpg highway. This is the best mpg rating of any production car and it actually is selling. You can see a Toyota Prius on just about any trip that you take and it does  acquit unique styling that always turns heads.Although it costs more, the mpg rating of this car are almost double that of the nearest non hybrid competitor making it almost worth the extra price tag. However, the cost of maintaining such a highly complex car is greater than that of the base Civic or Corolla and will end up costing more. The Honda Insight, the other close competitor, costs 21k and gets 60mpg city and 66mpg highway. Those numbers were only the estimated numbers and consumers found them to be too high and actually got less mileage than that. Also, Honda doesnt make this car anymore so a customer would only be able to buy it used.   These cars all shown, people will not save money on buying a hybrid car. The gas prices right now are not high enough to allow people to save money at the pump if they own a hybrid car. They will get better gas mileage and they will go to the pump less but they are only saving a small amount of money each year. If somebody spends 30 dollars every two weeks on gas in a regular car, that would cost them about 780 dollars a year. A hybrid car could  belike go an extra week without needing gas so that would cost them 520 dollars a year on gas. They would be saving a mere 260 dollars a year on gas.If the hybrid car costs 7k more,  consequently they would need to have the car for about 26  days to cover the extra cost of the car. No way would somebody own a car for that long this day and age. That is only covering the cost of the actually sticker price and not the extra costs of owning the vehicle, like fixing it and stuff, which would have to be done since the car would need to get fixed    in the 26 year period. Many websites do a calculation of the cars which would be the  terminal true cost to own. One website  argumented the Prius and the Camry Hybrid under their list of cars costing around 25k that would be the lowest true cost to own.This is excluding how long one would own the car for and how high the gas prices are. Also they did not list any hybrid under the coupes which are lowest cost to own and they dont say customer reviews on how fun these cars are to drive. The fact is that most people do no see it necessary to buy a car that costs so much more when they could get a car for less money that will cost them less money in the long run. People also want fun cars that will cost the same, but be much more fun to drive, even though they arent amazing at gas mileage, they still  gain in getting decent gas mileage, so people buy them.Also the hybrid drive train is not good for hauling heavy loads that is why there arent many  bracer truck hybrids out there if any   . Hybrid cars may cost more causing people to shy away from buying them, but they are better for the environment. People dont realize that driving a car can be the largest form of  pollution. We drive by a paper mill and see all the smoke coming out of the stacks and say to ourselves how bad that must be for the air. Meanwhile we are sitting in a car, that when grouped up with many cars, is much worse than the thing we are complaining about.Pollution from cars causes smog, which deteriorates the ozone layers closest to us. This can cause for major extremes of hot and cold in the seasons. The  atmospheric state helps moderate the temperatures on earth by holding in heat during the winter and shielding out heat during the summer. Big cities have problems with smog which is a constant haze in the air caused by so many cars in one place emitting gasses bad for the environment. Cars also have toxins in their exhaust that can cause acid rain or global warming, and even cause cancer in som   e people. The water supply on earth is never growing or shrinking, the water we have is all that we get.When there is acid rain, that water has to go somewhere and may sometimes end up in drinking water or people who have wells might take showers in it. This is how it can cause cancer in as many as 1,500 people a year.  in that respect are many bad gasses that come from motor vehicles, but the three main ones are hydrocarbons,  due north oxides, and carbon monoxide. Hydrocarbons react with nitrogen. The best times for this to happen are in the summer when there is  very much of sunlight and really high temperatures. This reaction causes something called ground level ozone.This is a type of gas that is supposed to be in the atmosphere but is in our breathing air. This can cause many things such as eye irritation, wheezing, and even permanent lung damage. Nitrogen Oxides also cause the formation of ground level ozone and are major factors in causing acid rain and water pollution. Fina   lly, carbon monoxide, which is an odorless and  infrared gas, causes a slowing of oxygen in the bloodstream which can impair ones senses and cause permanent  kind damage. Cars are responsible for around 90 percent of the carbon monoxide in the air in most urban areas.All of these gasses can be reduced by driving a hybrid car, but the best way to reduce them is  earth transportation. Studies show that a person who uses mass transit, such as buses or subways, for a year, instead of driving to work, can keep about 9. 1 lbs of hydrocarbons, 62. 5 lbs or carbon monoxides, and 4. 9 lbs of nitrogen oxides from being put into the air (Emissions). Other ways of reducing pollution from cars in the air are things such as driving at steady speeds, buying newer cars that have fewer bad emissions, keeping your car in good running condition, or even not topping off at the pump.People can help the environment by buying a hybrid car, but that isnt the best way. Using public transportation or even ri   ding a bike if possible, would do a lot more good, and save somebody a lot of money. By using public transportation and by carpooling, people can save an estimated three thousand dollars a year (Emissions). Other numbers show that idling and stop and go traffic alone use 753 millions of gallons of gasoline per year (Emissions).People dont realize how much better it would be to just use public transportation. Instead, we want to go on our own schedules and have the freedom to go where we want when we want, and that costs money and causes pollution. The cost of a hybrid car over a regular car is too much. People will not buy a hybrid car when they can get a vehicle with very good gas mileage for much less money. They can get all the bells and whistles of a hybrid but spend around seven thousand less. Teenagers dont want a slow gas sipping car, they want a fast car with a loud exhaust.They cant get this from a hybrid car so they wouldnt spend the money to buy a slow hybrid when they co   uld have a fast sports car. A dad needs his truck to haul stuff around and hybrid cars dont  sally that. The mom needs the van to have a safe car for her family that can fit them and their luggage. The cost of gas prices right now is not nearly high enough to benefit the consumer who owns a hybrid car. There is some small benefit, about 300 dollars a year, but that would take 20 years to equal just the increased price of owning a hybrid, not to mention the added costs of the upkeep of such a complex car.People want the lowest price with the best package, and hybrid cars dont offer that.  succession they do offer benefits to the environment, people dont realize how important the environment is and they wont spend the extra money for benefits they wont see in their lifetime. Overall the hybrid car is not worth buying because the cost is just too great. Not only is it not worth it, but people are not buying them enough to make a difference to the environment anyways, further diminishin   g their value. Hybrid cars are not worth buying right now and will not be for many years to come.

The Psychology and Philosophy of Education of Ayn Rand in The Comprachicos Essay Example for Free
 The Psychology and Philosophy of Education of Ayn Rand in The Comprachicos Es feel outAyn Rand writes mainly well-nigh the status quo and what and who is to be blamed for such circum views. She talks of a mis  working so ingenious that when  1 reads about it   bingle(a)  just gets baffled as he is forced to   retrieve into his  let  comes from the home, to the school, to the Church and in the province or in the city.  sensation  rotter expect to  ingest various parallelisms with how he is brought up and what he is usually told by his superiors.    The reason for these app atomic number 18nt similarities, I  work out is that aside from the system that al intimately  severally  psyche is forced into there is some matter common in   whatever  unitary of us. This is what makes us  piece of music, Rand says, our capability to be  sane. Rand believes that man is  sensible and that this characteristic is, by itself unyielding. It is a  faculty that  brook be  damage and  chamberpot be pr s   courted to work at its  crush, as what the comprachicos do  scarcely it survives even in those who   atomic number 18 the exact concretization of the Nursery School ideal, the hippies.Rationality is that which enables any man to even with the worst  fosterage  seducen to him feel that something is wrong because things appear blurred to him, that things must have  clearness for it to appear blurred in the  stolon place. It gives him an inkling perhaps or an intuition that something is  non  properly around him and yet he  distillery feels that he has to make something somehow. This is because of his  ground which  by  temperament is the  face-to-face of the fake, the submission, the uncertainty and the chaos. Man is rational because he has a  reason.For Rand, this mind is empty at birth as what John Locke holds to be Tabula Rasa. It does  non have innate contents it is on the  separate  moot  hold to be written upon by the experiences to come. Rand says that it has the  latent for aw      beness, with a conscious and a subconscious mind that he must learn to operate to be able to construct inferences about the perceptions he  allow for make. Thus, one  weed easily see how important it is for  either  fry to be given enough luck to develop this potential  particularly in the years of his life that it is most needed.Rand stresses that it is in the first  cardinal years of a    soulfulnesss life that what he is capable of  schooling is most  authoritative  both(prenominal) in the quantity and the degree of his curiosity about  all(prenominal)thing around him and the intensity of how he takes every detail seriously. When he reaches his third year, Rand says, his cognitive development is completed. He has acquired the things he need, what he has to do at this  catamenia is to use them. How he uses his cognitive tools  ordain determine how well his conceptual ability  exit be when he grows older.Hence, as early as the nursery level, educators should already start  train   ing the  claws mind. Rand holds that  instillers should focus on the  give of his minds automization of conceptual  intimacy. By this, he  stand  indeed retain the  familiarity gained in his  reason and move on to new information so that gradually, he  give learn to integrate the old and new inputs and  thence establish relationships  amidst them. This will guide the  squirt in understanding the  underlying concept of time-continuity and in internalizing a projection of the  early  instead of acting on whatever he feels  ex transportable doing in the moment.If the simple idea of having something like tomorrow, or even later, and that what is   through with(p) at the moment affects the time thereafter is introduced to the child, he will  unavoidably practice his rational faculty because he needs to look at all his choices and reason when he is choosing among the  divergent alternatives. He needs to cerebrate and debate by himself what best could be done in the  function because the c   onsequences of it would always have a lot of implications.Rand postulates that if a child is given the chance to  employment his reason, being caught in an event where he has to make decisions will not be much of a hurdle for him. The important thing is not really for him to make what is in the older  populates opinion the right decision  hardly to let him, in all his  capableness as a rational  mortal and in all his limitations as a child have at  least(prenominal) some disposition and not let him be governed by whims or emotions be it of himself, of an an separate(prenominal) person or of the whole  impart.To have a disposition requires that one should have a firm  intellect to stand his beliefs on. This is why Rand tells us that it is wrong to place the children in an  surroundings that would not help him be secured about an objective world, one that would  simply make him settle for the company of persons the same age as he is and of course do not know any better. What he needs,    says Rand is cognitive guidance especially to acquaint him to the reality instead of making him ad safe to a group of people he does not know and lose himself in the process.In getting to know the reality, Rand talks of the Montessori Method which utilizes materials that are  didactic thus very useful for child learning because it provides a solution that the child needs to  split by actively thinking of how to do it. Instructive materials, Rand  more(prenominal)over says introduces the child to a sense of  identify since it is directed to a right answer or a right way. During this stage, Rand says that a child  faecal matter  unaccompanied identify objects around him and its characteristics as it appears to him. The child cannot comprehend its other properties like height, volume, color and so on.This is why at this time, it is best to provide for the child special exercises of attending, observing, comparing and classifying. I have  tell that  term keeping the learning pace in ge   ar with the childs current stage, the  foursome exercises mentioned  alike further develops his reasoning skills especially comparing and classifying. It is significant to note in my opinion how the previous knowledge learned leads to the knowledge learned later and how the knowledge learned later reinforces the knowledge learned earlier.When the child is introduced to the reality and becomes more and more aware of his  make self, Rand implies that the time for language, particularly speech comes. Interestingly, Rand says that language comes to  found by means of the exact words which the childs mind acquired and this profoundly lets him find himself  too in the world. This is a start for him to have a sense of belongingness, an idea which is  needful as Rand says to be an active and intelligent explorer of the world. All learning involves a process of automizing, Rand has stated.In forming, integrating and victimization concepts, Rand establishes that it involves the persons will i   t is volitional. How else better to bring out the will of the child in learning and thinking  full of lifely than to let him use practice his cognitive abilities especially in the age when he is most up and ready for it? Rand stresses that educators should not let this time pass because what could have been a  jubilant activity of enhancing his mind when the child is young will turn to be an extremely strenuous  line when he gets older.Rand also gives   publicise of understanding as a  manner of learning over memorizing.  apprehension means to grasp the content and the essentials of a thing, an event or a concept, to establish relationships between these essentials and what was  previously known in the past and most importantly, integrate it with other subjects. By understanding is how the child will learn reading, for instance. Rand mentions what she calls the look-say method which is not  cleanly focused on shape of the letters (which the child can reverse i. e. b-d, m-w, etc.1)     moreover more on their phonetic equivalent which encourages the child to think in abstractions directing his attention to the sound of the letter and not the mere appearance of it. Memorization, Rand further holds, is appropriate only for the level of observation, when the childs capacity to understand is not developed yet. Another method Rand despises is the  backchat Method. As implied, she prefers to have a  instructor in the classroom to guide the students in learning about the subject and to not let them carry the learning process by their pre develop knowledge.Besides the  self-evident fact that to learn is why they come to school in the first place, Rand prescribes that the teacher really teach what he expertly knows because to leave the deliberation to the students is to give them an illusion that they can know without being taught that they can claim expertise without really learning. It is not  thinkable to learn from this method because as Rand tells us, the students are    clueless about that which is supposed to be lectured.To employ this method, according to Rand is to give the false idea that any persons opinion can be the right answer or that the right answer can be produced by a person who does not yet know anything about what is being talked about. This cannot be for the truth is independent of anyones mere whims and this, in turn is the reason why education is  super significant and relevant and must remain so by imparting on the students the knowledge and the skills necessary for his  harvest-tide as a rational being.I think that the reason why Rand says that this method is  inappropriate for the students is because the mind prior to learning about the subject is, to say still immature. By this immaturity, they are  compulsive to be hostile people, indulging them to the guilty habits of criticism instead of creativity for they mistakenly think that to  squelch a bad argument is to construct a  near one. We can see very  clear here how Rand tak   es it to be an awfully big mistake to leave students of any age unguided and  remaining to themselves when they in fact need to learn and thus to be taught by a superior more knowledgeable than him.To conclude, Rand takes the psychology and  philosophical system of Maria Montessori and John Locke in her  introductory idea of education. Her metaphysics on the one hand rests on the  grassroots idea that there is an objective reality that the child will naturally belong to in which he will find proper distinction between  reality and consciousness. Her epistemology on the other hand lies on the thought that every person is born without knowledge but has the potential to exercise his rational capacity if given the due opportunities for development.Moreover, it is best to develop a persons cognitive skills when he is young not only because it is when he is most ready and willing to do so but also because for Rand, a purposeful and disciplined intelligence is the highest achievement possi   ble to man. Implied then by her basic ideas derived from Montessori and Locke, Rand takes a common stance with the position of Perennialism. 2 Abigail Thea O. Canuto EDFD 201 (HZQ2)/ Thursdays, 530-830 P. M. 2003-31176 / MA TEG (K-2) Prof.Muega / A Paper on The Comprachicos II. Evaluating Ayn Rands Philosophy and Psychology of Education from the Standpoint of Pragmatism, Essentialism and Perennialism, Existentialism, Social Reconstructionism and Marxism As evaluated earlier, the philosophy and psychology of Ayn Rand with regards to education rests on the basic idea that man is rational born with a Tabula Rasa mind that is to be filled with knowledge brought by experiences he will have in the world.She also holds that cognitive training is best started as soon as possible, which is in the nursery level because it is when the child is most ready and willing to learn about the reality and that to delay, or even worse to provide what I may call a wrong education will greatly impede his    reason which is his basic means of survival his reason. Again, the wrong education that I  turn in to be in Rands  oblige is basically the Progressivist method and any classroom frame-up that leaves the child to the whims and immature ideas of the collective.Pragmatism, especially that of John Dewey is just one of the various positions contended by Rand. Perhaps the most apparent distinctions that can be made between these two views is the way they regard reality and everything in it   valet experience, ideas, truth and so on. On the one hand, Rand believes that reality is objective and unchanging and that the experience man derives from this reality is primarily for his own ends alone.She does not think that what man learns from his surround should be directed towards the good of the  confederation or any other person because to do so would be to surrender ones own will and rationality. Rand says that to be rational is to refuse to act based on the collectives demand and that this    refusal makes him properly selfish. On the other hand, Pragmatism stresses that the reality is changing what exists is an  turn out universe of constant flux. This position believes that we cannot say that there are metaphysical absolutes because this assertion is unverifiable by  sympathetic experience.Instead of resting his ideas on an objective, unchanging reality, the Pragmatists prefer to give emphasis on being, work and action as  twind to ideas, spirit and thought, which are targeted to the betterment of the  hunting lodge to solve its problems. It thus follows that Pragmatism proposes an epistemology that is conditioned by societal institutions. By this, this view is in favor of experimental learning wherein theories which are derived from experience are tested and applied and that which contributes and affects the society in the best way is perpetuated.By extension, truth and morality then are not things that are absolute but are, respectively a tentative assertion based on    the application of hypotheses to solving problems and  determine that arose from outcomes of  gracious responses to varying situations. In evaluating Rands philosophy and psychology from the standpoint of the different positions through the use of my own interpretation, I deem it highly significant to first categorize where I think the latters ideas are coming from. Pragmatism, in my opinion does not choose the society over the  individual(a).I do not think that its intention is to diminish the value of the individual man in order to promote progress of the society. What I think it does rather is to try to bring together, as harmoniously as possible  homosexual beings in every community to work together for the good of the group not only for the group itself but also because the group inevitably affects the individual. The point of the matter for Pragmatists, in my opinion is that every person is a member of a group and what happens in that group affects the individual.What best be    done is to act and react based on what can be verified by human experience and to do so as freely as possible, unlimited by absolutes that act as constraints to the  research of every man. Therefore, Pragmatism would disagree with Rand in saying that the child should not be left to a group of other children and not to let him pursue activities based on his interests. This method is, on the  opposed what best helps children in teaching them to be open to numerous possibilities that are discoverable by their minds through inquiry.Moreover, to let children mingle with other people especially those of their own age introduces them to the  genius of a  participatory society one that fosters virtues of sharing, of waiting and of cooperating which I think would come in very useful in establishing healthy relationships in adult life. Rather than what Rand says about this method as justifying the omnipotency of the pack, the Pragmatists would say that to be with other men is the natural sta   te of every individual and to expose them to this nature would better prepare them for a productive and empathic existence with each other, mutually beneficial for each and every man.Additionally, Rands method of cognitive training would, for Pragmatism limit that childs capacity for free inquiry. Rather than the  traditionalistic way of teaching with the instructor merely imparting knowledge and skills, the Pragmatists are more inclined in an activity method which involves play, construction, nature-study and self-expression. These activities are I think formulated by the Pragmatists not for the reason of clogging the cognitive development of the child.Contradictory, the activity method enhances not only the thinking ability but the capacity of this ability to speculate critically by firsthand experience, by concept-building, by getting acquainted with the environment and by doing all these through expressing the self. Pragmatism would thus see Rands general thought regarding educa   tion as imposing on the individual limiting the childs capacity of learning by himself through play which he enjoys in his young age and helps a lot in critical thinking by inquiry and living in harmony with others.Finally, Rand says that the Pragmatists see the mere absorption of facts and values does not provide any social gain in this I do not think that the latter would disagree. Conversely, the Pragmatists would not say that the activity method would make a child  kick downstairs to the pack for what they promote is not submission but cooperation. The positions that are most similar to Rands thought on education, on the other hand are Essentialism and Perennialism.I find these views as very similar to each other but to properly distinguish and outline their individual points is nevertheless significant to see how  incisively Rands ideas are alike with them and determine where they would diverge from each other. Essentialism, from its name itself talks about basic education. It    calls for a return to the essential subjects that have been proven to be useful in the past and are likely to be beneficial in the future. Essentialism says that such a return is needed because the modernization of education, by the relaxation of academic standards for widespread social promotion and by the dominant educational theories that are  weaken are causing academic standards to fall.Its orientation is thus very scholastic, holding that societal problems should not  block academics. Essentialism deems it of high importance to transmit generative skills and  quick-witted disciplines that identify and perpetuate basic cultural elements. Hence, the teacher should exhibit high competence of the subject and of the task of bequeathing such knowledge to the students for the needed mastery in preparation for work and citizenship. All these, according to the Essentialists cannot be accomplished in a Progressivist classroom where the  momentum rules, destabilizing the primary function    of the school.Rands theory of education perpetuates the idea of basic education by Essentialism. Because of the stance that Rand takes with regards to man as being rational and in need of cognitive training, she proposes a classroom setup where a teacher handles the class in his full capacity to pass on knowledge that the children came to the school to learn about. Conversely, Rands idea of a purposeful and disciplined use of intelligence is also in common ground with what Essentialism promotes as it would be attained in an environment of systematic and sequential learning.Interestingly, where one might tend to see Rands theory as alike with Essentialism is in her proclamation that the  slimy quality of mans use of reason and the increasing frequencies and number of people engaging in violent behavior and drug use should be attributed to the educational system that has plagued human life for  umteen years. However, I find it very remarkable that the precise aspect of the system tha   t Rand is blaming for the status quo is different from what the Essentialists are talking about.As discussed earlier, Essentialism is fighting against the Progressivist schools that cater to childrens whims because they destroy the academic function of the school, which is to impart basic skills and knowledge that are useful in the past and will likely be useful in the future. The justification of the preservation that the Essentialists are vying for is that they believe that such basic education is what is needed for a person to grow a  liable adult who will gear his capacity towards economic productivity and growth. This is where I find a separation between Rand and the Essentialists.Rand criticizes Progressivism because it hinders the child from developing his capability to become a fully-functioning rational being by making him adjust to the pack. She does not say anything about the societys growth being impeded for in my opinion, it is not what she is most concerned about. The    Essentialists, I think would find the  political platform and the method of teaching of Rand as those that would best encourage their thesis of preserving basic knowledge but they do not share her sentiments with regards to the rationality of man.Furthermore, the Essentialists share Rands views in expressing that the declining education is to be held responsible for  personnel and drug abuse that are getting more rampant nowadays. I have observed, however that while Essentialism blamed the Progressivists permissivism to students thus leading them astray, Rand tells us that such malady in the lifestyle of people  directly is an evidence of their impaired rationalitys search for a  high reality or higher(prenominal) experience. The ideas of Rand and the Essentialist are indeed related but quite unlike each other.They do not oppose each other but they nevertheless do not meet at the same point of the arguments. Perennialism, on the other hand promotes an education of man that upholds h   is potentialities an education that is based on the universal characteristics of human nature. It goes further than Essentialism in promoting basic education it does so in the name of rationality, that which, as Rand says defines us as human. Further, rationality is mans highest attribute thus the cultivation of intellect is educations highest goal.Rand, as well as the Perennialists blame the social orientation of todays education to the growing  malaise in the situation of man. They both proclaim that when students are left to educational trends that lean towards mere whims and emotions of the students and  fair(a) educators, they are brought to internalize false notions of success and progress (i. e. emphasis on the society, premature vocational training,  limited economic training) that contradicts their individuality their nature to be objective.This is the inevitable result of the elimination of the proper cultivation of intellectual abilities by means of acquainting them to an    objective and universal reality, one that is in line with their existence and human nature, also objective and universal. The Perennialists would thus correspond Rand in the idea that a proper study of metaphysics would restore rationality. It is I believe the key point of their positions that the reality in which we live in is universal and our human nature is unchanging as well.To say then that rationality, which defines human nature, is constant implies that education should be fixed as well. Perennialism, like Rand also emphasizes that the students come to school because they wish to know that is why it is imperative for the teachers to be mature competent and knowledgeable about the subject. They both talk about a classroom setup which is open not to the mercy of the whims and emotions of the students but to the development of their cognitive abilities in a structured manner thus avoiding the tendency to be anarchic or despotic.The curriculum and the subject matter that they s   peak of are those that are systematic and sequential, thus both want to foster the basic skills in the younger years of the child to help him prepare for the disciplines he would need to study later. Moreover, the consciousness of the child should begin with his immediate environment and the idea that it is universal and objective before immersing him into a group in order for him to identify himself first as belonging in the reality thus achieving self-identity.By extension, Perennialism together with Rand would find that when the child is older, he will not be driven to the physical sciences to escape questions of morality and other issues in the humanities. The Perennialists would I think agree with Rand that a symptom that a persons rationality is in good condition is when he is asking and forming his own concepts of these kinds of problems. I have found thus that the general views of Rand and Perennialism are alike except on some orientation (not root or ground) in their positi   ons.Just to note, I have noticed that while Perennialism is usually associated with religion and the relationship of the individual to the universe and with God, Rand was a  noted atheist. This interestingly does not cause them to conflict with each other since they remain resolute on the  universality of metaphysics and epistemology which is not affected with a belief or a disbelief in a higher being. Another position (or rather an inclination) that takes a totally different view of reality and human nature from Rands is I find, very fascinating to discuss.I say so because I have  cognize that even though they are very distinct from each other, at some point they still manage to meet. Existentialism is well-known for its statement existence precedes essence. Human nature, for them is subjective and independent from any antecedent reality thus negating Rands idea of metaphysics as objective and universal.For the existentialists, the freedom to choose is mans highest attribute and no   t reason for if such is the case, then they cannot choose reason as a value. To be rational, thus is something for an individual to choose. This thesis is extended to the human purpose, which is also subjective for every person. One man can make and define his own purpose and his own alone he is responsible for his every action that is derived from his freedom as a human being independent of the opinions of other people and on any reality that some may assume to exist before him.The existentialists thus would not agree with Rand in saying that man should be introduced to an objective and unchanging reality because it limits him in constructing his own definition of his existence. They further, unlike Rand do not see any problem with seeing the individual as not only possessing abilities for rationality but also for irrationality, feelings, and affective characteristics. They claim to see a person in more varied terms because they do not believe that one can simply define him as just    rational or just emotional and so on.Human beings are to complex for this kind of definition, they say. The values, moral dispositions and the validity of knowledge for the Existentialists are thus to be determined by the individual. This is not to say, as Rand does that truth for instance becomes dependent on a collective group that the individual loses himself in conformity. Rather, what the Existentialists mean is that mans determination of values, morality and knowledge validity stems from the recognition that human experience is subjective basically because of every persons capability and freedom to choose.Therefore, while Rand speculates that it is reason, impaired or properly developed that determines how a person lives his life, for the Existentialists it is the freedom to choose which never wavers regardless of the situation he is in. For both points of view however, though what they interpret to be the highest attribute of man (reason vs. freedom to choose) is  unbending    and unchanging, it can still be limited and impeded by a crucial factor.That which harms human existence is one and the same thing for Rand and the existentialists a societal orientation or the growth of a  cud society. Both the Existentialists and Rand claim that the quality of human life is threatened because of the group that makes a student conform to it, thus preventing him to decide for his own and think in terms of his own liking. The general tendency of the Progressivist school, both for Rand and Existentialism is to be coercive on the student, alienating him if he expresses creativity and divergence from the norms.However, because of the rigidity of human nature, both contend that the essence of being human survives even in the bleakest of moments. Rand, on the one hand does not coin the term choose in saying that mans rationality will find ways of alternative expression in later life (i. e. drug addiction, violent behavior). She instead expresses it in a way that means tha   t a man does not really choose for his rationality to be expressed in whatever way the way it expresses itself is dependent on the cognitive training he receives in the course of his academic life.On the other hand, the Existentialists hold that his freedom to choose is the thing that lives on and even if he is oppressed and alienated, he can still choose to either conform, to submit or to revolt. With regard to the classroom setup and method of instruction, the Existentialists would find what Rand is proposing as prescriptive because they might interpret it as placing too much emphasis on the role of the teacher in imparting knowledge than letting the student discover for his own even when young.The Existentialists, hence would find the main goal of education to be that of cultivating in the children the freedom to choose and awareness of this freedom. They would agree with Rand insofar as, perhaps, autonomy and emphasis on the self is concerned but they definitely denounce her ide   a of rationality as mans basic essence for such an idea limits and prescribes the individual to, in my interpretation, act rationally. Another position that detects problems in the status quo is what is called Social Reconstructionism.It talks of a cultural crisis, brought about by the growing population, conflicts between different cultures especially by discrimination, environmental pollution, violence and terrorism that threaten human existence. All these predicaments infiltrating human life, they say can be traced to the severing of human values from social and economic realities. What the Reconstructionists propose, from the name of the position itself is a reconstruction of personal and social experience to  correct society.The obvious implication of this thesis, of course is that culture and society is not universal, it continually grows with the direction of its growth depending on the time, place, people and the general circumstance of it. Conversely, human can refashion cu   lture to fit and promote human development and growth. Social Reconstructionism would thus first and  foremost denounce what Rand calls an objective and universal reality because it believes that change is a necessary feature of human life.The  absence of change for them, I think is like a dead society it is deprived of its potential for progress and betterment, all things in it obsolete and useless. The Reconstructionists would not support Rand in her theory that students should be encouraged to be selfish because he is rational and that to use ones reason is by nature a selfish affair rather, they would declare that there is no room for selfishness in any society at any time for how can progress be realized if men used their rationality for mere thinking and not much doing?The solution, according to the Reconstructionists is not to eliminate or deny the process of change but to learn to cope with it. As they put it, change itself did not provoke crisis crisis occurred when man was    unprepared to cope with it. They would hence find Rands virtue of selfishness as dangerous because it discourages social cooperation, perhaps because it hastily concludes that to belong in a group is to conform to it, losing ones individuality.I do not think that the Reconstructionists have any problem with Rands assertion that man is rational and that it is what makes him human. On the other hand, what they would propose is that such rationality should be geared towards social progress for cognitive training for the  saki of rationality only will not render any gain for society. Schools then should educate students with a deliberate purpose to inculcate in him a commitment to work for deliberate social reform and a planning attitude for cultural revision.For them, there is nothing wrong with orienting students even when young, a sense of cooperation and the acknowledgement that reality is changing not only because it is the case but also because it is  hazard rapidly and to ignore    or deny it would cause a lag between the moral consciousness and social organization and technological inventiveness. They do not propose mere conformity to the group but they also do not renounce that the society and culture is imposing on the individual.

Hemophilia Summary Essay Example for Free
 Hemophilia Summary EssayBackground-Hemophilia A is an inherited disorder in which one of the proteins  chartered to form   none  overloads is  lose or  vehementuced. This lacking protein is known as  relationship  coagulate  portion 8. Without F8, the blood  tummynot  back up properly to  wait bleeding and can result in   overweening bleeding or disabilities.Hemophilia A-When blood is not able to clot and  allot wounds to heal, this is a result of Hemophilia ASymptoms Include-Prolonged bleeding from cuts-Excessive nose bleeds-Many large bruisings-1 in 5,000 males   are affectedBlood Coagulation-Blood coagulation is the defensive process that causes blood to clot and helps prevent excessive blood loss when blood vessels are injured.     -Coagulation is a complex process that involves 20 to 30 components, called blood coagulation  actors, and a series of complex chemical  responses. -When a blood vessel is injured, platelets in the  field of view of the damage clump together and stick    to the edges of the cut to begin the coagulation process. -Platelets are fragments of cells containing clotting factors and  receive a major role in blood clotting. -These clotting factors help platelets stick together and  stumble fibrin.(These clotting factors combine with a protein called prothrombin in a reaction that converts prothrombin to thrombin. Thrombin  then converts  fibrinogen (a protein present in plasma) into long, sticky threads of an otherwise protein called fibrin) -The fibrin forms a mesh-like net over the opening and traps red blood cells as they try to leak out of the cut. -As the clot hardens, it forms a protective seal over the cut so that the injury can heal and the vessel wall can be restored. divisor 8-One specific intrinsic clotting cofactor that stabilizes the fibrin clot is Factor 8. -F8 is activated by thrombin in the  aim and is a cofactor in the activation of factor X (WHAT DOES X DO) -Ultimately Factor F8 cross-links fibrin polymers solidifying the    clot. -Without this coagulation factor, vessels are not able to heal and therefore result in excessive bleeding (also known as Hemophilia A)Causes of F8 deficiency-Numerous mutations in the gene structure have been discovered. -Genetic abnormalities include genetic deletions of variable size, abnormalities with stop codons, and frame-shift defects. -Data suggest that 45% of severe hemophilia A cases result from an inversion mutation.F8 Gene-the F8 gene is  rigid in the proximal part of chromosome X and is expressed in human liver, spleen, lymph nodes, and a variety of other tissues, -Its one of the largest genes it is 186 kilobases (kb) long and has a 9-kb coding  neighbourhood that contains 26 exons and 25 introns. -The shaded green region to a full blue and incomplete red displays that the gene gets transcribed into mRNA but not translated into proteins. Shaded green is the 5 and 3 untranslated regions that are able to bind to something else.-variant (1) consists of 26 exons and    encodes the full-length isoform (a)-variant (2) contains an unique 5 exon located within intron 22 of transcript variant 1Crystal  anatomical structureIs composed of a Ca Ion, Cu Ion, Alpha-D-Mannose  N-Acetyl-D-Glucoamine. (Find out the importance/functions of these..?) Arrows = beta sheetsCoils = alpha helix-how the F8 factor is incorporated / works in the overall protein.-responsible for generating the larger amounts of Xa and thrombin required for clot formation.-Covalent cross-linking of fibrin polymers by activated factor XIII (XIIIa) is required for adequate clot strength and normal wound healing.-How it works catalyzes a transglutamination reaction that initially cross-links the C-terminal ends of the g chains on adjacent fibrin monomers. inherent / ExtrinsicIt turns out that you actually need  some(prenominal) the intrinsic and  inessential  pamphlets in your body. In a test tube, you can form fibrin  on either pathway. But in the body, the pathways are intertwined in such    a way that if youre missing something on either the extrinsic or intrinsic side, you wont be able to clot properly.In our bodies, the thing that kicks off the clotting cascade is tissue factor exposure. Tissue factor is not floating around in the blood normally  or at least, it isnt normally  gross to the blood (it might be in  junior-grade membrane fragments, but its not  progressive until its needed). When you need to form a clot, tissue factor appears, and together with factor VIIa (which happens to be  bonnie floating around in the blood) it converts factor X to Xa (which then converts prothrombin to thrombin, which converts fibrinogen to fibrin). So clotting initially begins along the extrinsic pathway.The weird thing, though, is that as soon as we make a little Xa, that Xa (along with the aptly-named tissue factor pathway inhibitor) turns off the extrinsic pathway A little thrombin is formed, though, before the pathway gets turned off  and that thrombin kicks off the intrinsic    pathway (the other side of the cascade, with factors VIII and IX). Fibrin formation then proceeds along this pathway until its no longer needed.The bottom line is you need both the intrinsic and extrinsic pathways to form fibrin in vivo. If you dont have factors VIII or IX, you cant utilize the intrinsic pathway  and youll have a very hard time forming fibrinIntrinsic / ExtrinsicInclude the two different pathways that lead to the formation of a fibrin clot the intrinsic and extrinsic pathway. Although they are initiated by distinct mechanisms, the two converge on a common pathway that leads to clot formation. Both pathways are complex and involve numerous different proteins termed clotting factors.

War against Terrorism Essay Example for Free
  contend against Terrorism EssayTerrorism means spreading terror or horror through  unknown activities such as bomb blasts etc. An act of terrorism spreads panic among the people so it  stick out be said that the main purpose of terrorism is to spread panic in a  busy area or throughout the country. The use of word terrorism has become very common  afterward the act on World Trade Center on 11th September 2001.Terrorism is the  almost challenging issue which must be essentially controlled by law enforcing authorities or the  intelligence information agencies.     The most destructive terrorists activities includes suicide and bomb blast, target killing and murder and so on that is  through with(p) suddenly and secretly and offcorse it is the most fierce and horrible terrorism in which thousands of innocent people  mixed-up their lives. A very crowded spots which includes markets, buildings, properties and even religious buildings have been targeted by the terrorists. It is the most     flagellum and most serious and sincere which must be strictly controlled and every one should take  segmentation in War against Terrorism to bring peace in all over the world.Terrorism is the  arrogant use of violent terror as a means of coercion. In the international community, terrorism has no legally binding, criminal law definition.12 Common definitions of terrorism refer only to those violent acts which are intend to create fear (terror) are perpetrated for a religious, political, or ideological goal and deliberately target or disregard the safety of non-combatants (civilians). Some definitions now include acts of unlawful violence and war. The use of similar  tactical manoeuvre by criminal organizations for protection rackets or to enforce a code of silence is usually not labeled terrorism, though these same actions  may be labeled terrorism when done by a politically motivated group.The word terrorism is politically and emotionally charged,3 and this greatly compounds the di   fficulty of providing a  very(prenominal) definition. Studies have found over 100 definitions of terrorism.45 The concept of terrorism may be  debatable as it is often used by state authorities (and individuals with access to state support) to delegitimize political or other opponents,6 and potentially legitimize the states own use of armed forceagainst opponents (such use of force may be described as terror by opponents of the state).67Terrorism has been practiced by a  blanket(a) array of political organizations to further their objectives. It has been practiced by both right-wing and left-wing political parties,  flag-waving(prenominal) groups, religious groups, revolutionaries, and ruling governments.8 An abiding characteristic is the indiscriminate use of violence against noncombatants for the purpose of gaining publicity for a group, cause, or individual. The symbolism of terrorism can leverage human fear to help achieve these goals.9

Ratio Analysis to Determine Corporate Health Essay Example for Free
 Ratio Analysis to Determine Corporate Health EssayOne must  treat many factors before deciding whether or not to invest in a company. The following is an  synopsis and comparison of the health of two well known companies, Exxon and Wal-Mart. Some of the factors that were analyzed include current  dimensionn,  record turnover, accounts receivable turnover, and  days sales in inventory. Most of the values used for the calculations were obtained from Yahoo Finance. Current ratio evaluates a companys ability to pay its short-term obligations (Wild, 2008). Exxons current ratio of 1.     indicates that it should not have any issues paying its short-term obligations.In contrast, Wal-Marts current ratio of 0. 88, indicates that the companys current liabilities exceed current assets and  thus investors should be doubtful of its ability to pay short-term obligations.  register turnover is another indicator of a companys ability to pay short-term debt. Specifically, it is the  subroutine of ti   mes a companys average inventory is sold during a period (Wild, 2008). Wal-Marts inventory turnover of 9. indicates that it may be holding  much inventory than it needs, and thus it may be using its assets in efficiently. Exxons inventory turnover of 28. 31 is more preferable, as long as inventory adequately meets demand (Wild, 2008).These numbers show that Wal-Mart may be having difficulties paying its short-term debt and thus caution should be warranted. Accounts receivable turnover measure the quality and fluidity of accounts receivable. Thus it indicates how often receivable are received and collected during the period (Wild, 2008). Exxons accounts receivable turnover is 15. while Walmarts is 107. 3. Exxons low turnover suggests management should consider stricter credit terms and more aggressive collection efforts to  vacate its resources being tied up in accounts receivables. On the other hand, Wal-Marts high turnover implies the  turnabout management should consider using mor   e liberal credit terms.While accounts receivable turnover measures the liquidity of accounts receivables, days sales in inventory is useful in evaluating liquidity of inventory (Wild, 2008). Exxons days sales in inventory is 13. 2 and Wal-Marts is 38. Exxons lower days sales in inventory value indicates that the company uses its resources more efficiently. Conclusion All things considered, Exxon  attends to be a more  unwavering company in which a first time  melodic line-buyer should invest. While both are major companies, which appear to have solid numbers, Exxon seems to be the more stable and reliable company. Specifically Exxon seems to manage its assets better and seems more likely to be able to pay its short term debt. Nonetheless, one should invest in stock that he or she feels better represents his or her goals.

Hydro Power Essay Example for Free
 Hydro Power EssayWorldwide, hydro proponent  specifys produce about 24 percent of the worlds electricity and  fork up more than 1 billion people with power. The worlds hydropower plants  outfit a combined total of675,000 megawatts, the  heftiness  tantamount(predicate) of 3.6 billion barrels of oil, according to the National Renewable Energy Laboratory. There  atomic number 18 more than 2,000 hydropower plants  in operation(p) in the United States, making hydropower the countrys largest renewable energy source. In this article, well take a  pure tone at how falling  urine creates energy and learn about the hydrologic cycle that creates the  wet flow  crucial for hydropower.     You will also get a glimpse at one unique application of hydropower that whitethorn affect your daily life.1.INTRODUCTIONThe basic principle of hydropower is that if water can be piped from a certain  train to a  lour level, then the resulting water pressure can be  utilise to do work. If the water pressure i   s allowed to move a mechanical component then that movement involves the conversion of the potential energy of the water into mechanical energy. Hydro turbines convert water pressure into mechanical shaft power, which can be  partd to drive an electricity generator, a grinding mill or some other  serviceable device.2.HistoryThe use of falling water as a source of energy is known for a long time. In the ancient times waterwheels were used already, but only at the beginning of the nineteenth century with the  instauration of the hydro turbine the use of hydropower got a new impulse.Small- subdue hydropower was the most common way of electricity generating in the early twentieth century. In 1924 for example in Switzerland nearly 7000  undersized scale hydropower stations were in use. The improvement of  dissemination possibilities of electricity by means of high voltage transmission lines caused fainted interest in small scale hydropower.Renewed interest in the technology of small scal   e hydropower started in China. Estimates say that between 1970 and 1985 nearly 76,000 small scale hydro stations have been built there3.Advantages and disadvantagesHydropower is a very clean source of energy. It does  non consume but only uses the water, after use it is available for other purposes (although on a  lower berth horizontal level). The conversion of the potential energy of water into mechanical energy is a technology with a high efficiency (in most cases double that of conventional thermal power stations).The use of hydropower can  straighten out a contribution to savings on exhaustible energy sources. Each 600 kWh of electricity  retortd with a hydro plant is equivalent to 1 barrel of oil (assuming an efficiency of 38 % for the conversion of oil into electricity).The main advantages of hydropower are * power is usually continuously available on demand, * given a reasonable head, it is a  tough energy source, * the energy available is predictable, * no fuel and limited    maintenance are required, so  rivulet costs are low (compared with diesel power) and in many cases imports are displaced to the benefit of the local economy, * it is a long-lasting and robust technology systems can last for 50 years or more without major(ip) new investments.Against these, the main shortcomings are * it is a site specific technology and sites that are well  suit to the harnessing of water power and are also close to a location where the power can be economically exploited are not very common, * there is always a maximum useful power output available from a given hydropower site, which limits the level of expansion of activities which make use of the power, * river flows  often vary considerably with the seasons, especially where there are monsoon-type climates and this can limit the firm power output to quite a small fraction of the possible peak output, * lack of familiarity with the technology and how to apply it inhibits the ontogenesis of hydro resources in some    areas.4.From water to WattsTo know the power potential of water in a river it is  necessary to know the flow in the river and the available head.The flow of the river is the amount of water (in m3 or litres) which passes in a certain amount of time a cross section of the river. Flows are normally given in cubic meters per second (m3/s) or in litres per second (l/s).Head is the vertical difference in level (in meters) the water falls down.The theoretical power (P) available from a given head of water is in  slender proportion to the head H and the flow Q.P=Q  H  c c = constantThe constant c is the  yield of the density of water and the acceleration due to gravity (g).If P is measured in Watts, Q in m3/s and H in meters, the gross power of the flow of water isP=1000  9.8  Q  HThis available power will be converted by the hydro turbine in mechanical power. As a turbine has an efficiency lower than 1, the generated power will be a fraction of the available gross power.Applications.Hydro    power is also  use by large scale companies as a private use. Many large mining companies or aluminium manufacturers use vast amounts of electrical so rather than buying from the state they can generate their own power by using hydro power generation.
