Neurotransmission - Term Paper Example x support the neurons, digest the dead neurons, and manufacture the protective myelin sheath covering the neurons besides providing nutrition (â€Å"Brain Cells’’ 2001). Thus neurons along with their connections can be visualized as electric conductors insulated in a thick mass of glial cells. A typical neuron, like other cells has a main body in which resides the nucleus and is called soma (Fig. I). From this emanate the inward signal processing projections called the dendrites and the outward signal processing axons, or the conducting fibres (Case Presentation, January 27th, 2014). The point where the two neurons connect with each other is known as the synapse, the latter being the juncture where transmission of axonal information takes place (Case Presentation, January 27th, 2014). A synapse is comparable with a connecting switch which transmits current from one circuit to another. Dendrites receive the incoming signals from the preceding neuron, the signals being generated in the form of micro electric action potentials in the soma, wherein the signal processing and stabilization takes place. The axons transmit the information from the prior to the subsequent neurons. The fatty myelin sheath serves to insulate the axon thereby facilitating transmission of signals. This myelin sheath is akin to the insulation we see on electric wires. As the insulation on electric wires stops leakage of electric current thereby protecting us, similarly the myelin sheath on the neuron protects leakage of action potential to adjacent neurons so that they can send signals along the actual destined pathways for them. However, at specific intervals it exposes the neuron at junctures called ‘Nodes of Ranvier’ which are meant for increasing the speed of transmission of the onward electric signals. A typical neuron connects with 1000-1000 other neurons through synapses (â€Å"Brain Cells’’ 2001). This can be compared to a big power supply line feeding hundreds of houses for

Plato and Aristotle Essay Example for Free

Plato and Aristotle Essay 1. What are the major differences between Plato and Aristotle? Make sure you provide examples. Basically, Plato and Aristotle are highly different in their philosophical beliefs and their various teachings.   The main philosophy of Aristotle is to possess virtue in order to achieve the ultimate goal which is happiness. In order for people to possess virtue, he also believed that everything should be done in moderation only and not too sparse or too excessive. On the other hand, Plato used logic and dialogue as his main tools together with the aid of mathematics in order to arrive with rational conclusions so as to know the universal truth. Moreover, Aristotle strongly believed that acts of good must be habituated in order to become a virtue while Plato believed that merely knowing what is good is enough to be able to do good even without actually doing it. Another major difference between the two is their beliefs in metaphysics. Plato’s believed that there are higher or ideal forms that can only be acquired through knowledge while Aristotle believed that form and matter are inextricably bound and coexist. 2. Are you a Platonist or an Aristotelian? Provide specific examples to help illustrate your points. I am basically a Platonist simply because there are more of this teachings that are applicable today than Aristotle such as his theory of the universal ideal forms. For example, when looking for an ideal friend, that person I am searching for must possess the qualities that I desire. However, it is a well-known truth that there is no such thing as â€Å"perfect† or â€Å"ideal.† But since I know what an ideal friend is, I now have a pattern which I will use as a basis as I search for my ideal friend. I may not be able to find that person but I would definitely meet someone close to that, which is like the shadows that Plato described in the Allegory of the Cave. In addition, I know that the both the sky and a pair of blue jeans are both color blue. Although, in reality, they are not of the same color, I somehow have an idea of what blue is because it preexists in my mind.   Another reason that I also consider myself as a Platonist is because I do not believe in Aristotle’s idea that by possessing virtue, once can achieve happiness. For me, his belief is too idealistic, although his use of formal logic and scientific methods such as deduction and observation is still applicable today.

freeaw The Awakening as a Story of Independence and Freedom :: Chopin Awakening Essays

The Awakening as a Story of Independence and Freedom Kate Chopin's The Awakening is a work of fiction that tells the story of Edna Pontellier, Southern wife and mother. This book presents the reader with many tough questions and few answers. It is not hard to imagine why this book was banished for decades not long after its initial publication in 1899. At that time in history, women did just what they were expected to do. They were expected to be good daughters, good wives, and good mothers. A woman was expected to move from the protection of her father's roof to the protection of her husband. Edna didn't fit this mold, and that eventually leads her husband to send for a doctor. It is here that Edna Pontellier says words that define The Awakening, "I don't want anything but my own way. That is wanting a good deal, of course, when you have to trample upon the lives, the hearts, the prejudices of others - but no matter_" As the book begins, Edna is a married woman who seems vaguely satisfied with her life. However, she cannot find true happiness. Her "awakening" begins when a persistent young man named Robert begins courting her. Edna begins to respond to him with a passion she hasn't felt before. She begins to realize that she can play roles other than wife and mother. Throughout the book Edna takes many steps to increase her independence. She sends her children away, she refuses to stay at home on Tuesdays (as was the social convention of the time), she frequents races and parties. Unfortunately, her independence proves to be her downfall. Edna stays married because divorce was unheard of in those days. She wants to marry Robert, but he will not because it will disgrace her to leave her husband. No matter how much Edna exceeds social boundaries, she is held down by the will of others, despite what she wants. In today's world divorce, sadly, is almost commonplace, but in her time she would have been an outcast of her society. By the end of The Awakening, Edna feels like a possession - of her husband, of her children, and of her society. The only solution she sees is to end her life, which she does by swimming out into the sea until her strength gives out. This is a very symbolic death. I feel the theme of The Awakening is deeper than the obvious themes of independence and women's rights. The Awakening presents suicide as a valid solution to problems that do not offer many choices.

Is Gaming Harmful?

Is Gaming Harmful? Video and computer games, like many popular, entertaining and addicting kid activities, are looked down on by many parents as time wasters, but why? , is it because they are harmful? , or is it simply because they are spending too much time on them instead of studying. Both have many good arguments, but I am going to write about the one in which I feel are most valid. One of the many good points against gaming is that children, teenagers and adults alike are losing sleep over video games because they are staying up all night and letting their â€Å"addiction† take over.The definition of addiction is: â€Å"The condition of being habitually or compulsively occupied with or involved in something. † And anyone who likes and plays videogames has experienced this at some point. Its not only kids that think about going home from school to play video games, many adults think about at work too, the average game player is 30 and has been gaming for about 12 ye ars. This means that many people, no matter of their age or sex, are putting video games before their school or work by missing out on important sleep and not putting their full concentration into their work.On the other hand, Gaming has been proven to increase social skills in young people as most games include a multiplayer feature that encourages people to play the game with others, whether it be online with friends or sitting together which is important for young kids growing up as it helps them make friends and sustain relationships. It also helps them realize how important it is to be sociable when they are starting school or a new job.Although some could argue that video games can do children social harm as many children play there selves for many hours each day and rarely interact with their family or friends. They could also argue that video games can cause great physical harm. The physical harm can occur when the child spends long hours of concentration on fast movement or because of the screen flicker. Also when children play video games they sit in for long hours that in the long run will stunt their natural growth and damage their backbone.Video games are more commonly known as a hobby you do sitting down somewhere comfortable and relaxing but what most people fail to realize is that there are a new type of video game emerging that get you on your toes and exercising. These include such consoles as PlayStation Move, Xbox Kinect , Wii, etc. These devices are designed to keep you active while you game and can give you a good physical work out instead of playing seated, these kind of games also can give you a good mental work out as most games for these console require lots of problem solving and also help improve your hand eye co-ordination skills.However, there are some that would say playing videogames can cause mental and psychological harm. Their reasons for this are they believe that when playing video games, children do not apply much mental e ffort and believe that video games are not creative enough. This could lead to the child developing lazy mental habits and also being impatient as real life is not as fast as their game might be. There are also some that believe that children can become violent because they become habituated to the violence that occurs in some games they might play.

Indra Nooyi †Leadership Style Essay

Indra Krishnamurthy Nooyi, who is a woman comes from India, she is a manager and leader of PepsiCo Incorporated. At her age of 50, she became the CEO. Leader is a role of a team or organization, the ideas he/she thinks about and the strategy he/she decides will play an important role in a group. In addition, being a successful leader generally needs to have more high requirements, such as the managerial knowledge, communicational skill, creative ability and especially his/her leadership style. There is no doubt that Nooyi can be equal to such a great position today because she not only is equipped with these conditions but also she has an excellent leadership style. According to Darling and Leffel’s (2001) framework, this paper will evaluate how Indra Nooyi develops her leadership style of Analyzer and Director and become a successful as well as effective leader. Kreitner and Kinicki (as cited in Darling & Leffel, 2001, p356) state leadership is a process where on individual guide and assist a group to achieve a common goal. Being a successful leader, he/she should have profound knowledge as well as skills. Additionally, Leadership is distinguished form management and this distinction is crucial. Kotterman (2006) explains that to management is that taking responsibility to accomplish and conduct the tasks as well as target. However, he also states that to lead means to direct and influence by an action as well as opinion. Furthermore, Darling and Leffel (2001) point out that leadership styles can be classified into four types which include Analyzer, Connector, Director and Creator, all of which are various. However, different leaders and styles are required in different situations, which is what Morrison (2000) illustrates that different leadership styles generate different influence and significance on the entrepreneurial spirit. According to Darling and Leffel (2001), by analyzing the four main leadership styles, Indra Nooyi, CEO of PepsiCo, could be regarded as an Analyzer. Analyzers generally are system, cautious. Searching information and collecting a large number of data are always required before analyzers performing tasks. Analyzers also are diligent, objective. They always are not emotionally and they can control themselves well. In addition, analyzers generally manage clearly and orderly, when confronting with the bad  situations or major problems they will not easily compromise (Darling & Leffel, 2001). Nooyi is such a type of leadership. In 1994, Nooyi analyzed the market and she found that the growth rate of Fried food and quick meals which are â€Å"unhealthy† food of the restaurant industry gradually developed slowly because people started to focus on healthy eating and nutrition problems. Then, Nooyi decisively proposed to spin out the food and beverage business, split over the canned business at the same time and listed them individually, all of which can reduce the fixed capital and promote the overall influence of PepsiCo (Jagannathan, 2009). Moreover, Nooyi identified the market and recommended that stop in carbonated beverages tend to be saturated market competition environment and open up new fruit drinks market as she considered that promoting healthy food and drink is very significant for building PepsiCo’s brand image. In 1998, Nooyi acquired Tropicana which is fruit juice company brand and product line (Hays, 1998). In addition to a Director style, Nooyi also could be considered as a Director. As Darling and Leffel (2001) explain the style of director is pragmatic; they are clear about their tasks and goals and are able to work steadfastly in accordance with this direction. What is more, they always pay attention to the results. Director is confident and determined; they not only like to accept new challenge but also have the courage to take risks. As a CFO, in 2001, under the direction of Nooyi, Pepsi Company completed the acquisition of Quaker Oats (Quaker Qats) 2002 R & D efforts to develop healthy products and all the products are divided into three categories: the â€Å"beneficial class† (good for you), â€Å"health class† (better for you) and â€Å"fun† (fun for you), as a consequence, PepsiCo’s non-carbonated beverage industry in the world to occupy a market share of 25%, 1.5 times that of the major competitors of Coca-Cola. After Nooyi became CEO of PepsiCo, She began to pay attention to PepsiCo products health and balanced concept through the acquisition and product innovation, further enrich the product line. Specific measures are successfully merger and acquisition Stacy’s Bagel, Pita Chips, Izze carbonated drinks business in North America, there are also including fruit and vegetable juice drinks ( Jagannathan, 2009). Nooyi not only can be considered and regarded as a successful manager but also can be an effective leader. To illustrate Nooyi’s effectiveness,  looking back on the performances that Nooyi achieved, for example, when Nooyi was SVP, due to her strategy measures that are logical, serious and thorough, the profits of sales of the company were grown a lot, which rose from US$ 20,337 million in 1996 to US$ 26,935 million in 2001 (Jagannathan, 2009). What is more, Jagannathan (2009) mentioned that during that period Nooyi as CFO, the growth of sales of the PepsiCo increased from US$ 25,112 million in 2002 to US$ 35,137 million in 2006. Most importantly, with the great efforts of Nooyi, PepsiCo Company has been built up a positive and healthy brand as well as image around the world. In conclusion, by synthesizing the explanation of Darling and Leffel’s (2001) framework, it is obvious that the characters of Nooyi’s Analysis as well as direction are showed extremely well. Those strategies which include the spin-in of food and beverage business, the acquisition of Tropicana as well as Quaker Oats all prove Nooyi has highly keen analysis ability and long-term vision. Undoubtedly, Nooyi plays a curial role in Pepsico Company, without the smart analysis as well as audacious decision of Nooyi, and if Nooyi do not focus on vision as an Analyzer and Director, PepsiCo may not obtain such great achievements. In the future, people believe that Nooyi will develop and strengthen PepsiCo Company more and more efficiently with her â€Å"performance with purpose† strategy.

Kandinsky essays

Kandinsky essays Analyze Kandinskys sources for his abstract works. In order to fully understand the art of Kandinsky, it is important to start with a definition of the word Abstract (for it is not really a concept that we have come across, before in this course). Abstract art does not depict recognizable scenes or objects, but instead is made up of forms and colours that exist for their own expressive sake. In short it abandons the European tradition, the idea of art as the imitation of nature. Kandinsky, in a work known as the First Abstract watercolour dated 1910 is often cited as the first person to paint an abstract picture. His work, his achievement in the search for a new form of expression in painting and a new conception of art in general, may look as though it has no precursors, however, in his case as with all other artists there are there were many influences which he encountered throughout his career, which had a profound effect on his road to the abstract. We can start with his childhood. Kandinsky lived in Russia until he was 30 and his experiences were crucial to his development as an artist. The general impression of his early life in Russia (as with most middle class Russians) must be one of backwardness. He was drawn to a particular class of people, whose main aim was to bring their country up to speed with the rest of Europe. As a result he was made to feel that art was an uncalled for luxury. To try and help his country he decided to study law and political economics at university, however his interest in economics waned after his first real introduction to the arts. He once said I love painting more than anything. It is clear that Kandinskys growth as an artist and intellectual were marked by a rejection of materialism, and a leaning towards spiritualism. Certainly his move towards abstraction was motivated by his avoidance of the material world, brought on...
