Solar Energy And Its Social Consequences Essays - Energy Economics
Solar Energy and Its Social Consequences To understand the social consequences of solar energy, one must be aware of what solar energy is. Solar energy is a radiant energy produced in the sun as a result of nuclear fusion reactions. It is transmitted to the earth through space in quanta of energy called photons, which interact with the earth's atmosphere and surface. The strength of solar radiation at the outer edge of the earth's atmosphere when the earth is at its average distance from the sun is called the solar constant. The intensity of energy actually available at the earth's surface is less than the solar constant because of the absorption and scattering of radiant energy as photons interact with the earth's atmosphere (Thorsen, 1997, Encarta). The amount and strength of the solar energy available at any point on the earth depends on the day of the year, time of day, the latitude of the collection point, and the orientation of the object used in collection. The earth is rich in abundant natural resources. However, the earth's natural resources are being consumed at an astronomical rate. It will only be a matter of time before those resources are depleted and we are forced to consider other alternatives. We can wait until every resource has been consumed and go back to living the way mankind did a century ago, or we can continue to move forward and explore the possibilities of harnessing the power of something that remains constant in our lives?the sun. Mankind has been using the natural energy of the sun for ages. Interactions between the sun's energy, the oceans, and the atmosphere produce winds that have been used for centuries to turn windmills. Modern applications of wind energy, when attached to generators, produce electricity. Through photosynthesis, solar energy contributes to the growth of plant life masses that can be used as fuel, such as alcohol or methane. Solar energy is a clean and safe source of natural energy that should be considered as an alternative energy source for the future. The sun is not indigenous to any one country. It is a resource that can be utilized globally. Individuals and countries could possibly become more self sufficient in energy resources (Alcorn, 1997, p. 212). An idea that has been proposed to produce power on a large scale would involve placing giant solar modules in earth's orbit where energy generated from sunlight would be converted to microwaves and beamed to antennas on earth to be converted to electric power (Thorsen, 1997, Encarta). To produce as much power a five nuclear power plants, ten million pounds and several square miles of solar collectors would have to be assembled in orbit and an earth based antenna five miles in diameter would be required. This vision requires an exorbitant amount of money. To my knowledge, there isn't a government on earth that is willing, thus far, to fund such a project. The potential future uses of solar energy are confronted with opposition. So far, the cost of constructing devices that would be able to harness a free energy source is at the top of the list. I realize there is a lot of money involved, but I really can't think of any technological discovery that was free to begin with. Every invention has come about through scientific research, and research requires money. Some have expressed concern regarding certain industries having to change their products to supply the new needs of society (Alcorn, 1997, p. 213). Due to new and expected futures advances in technology, the world will always be forever changing. Some industries will initially absorb some monetary and opportunity costs, but it is the price they will have to pay for progression. Another public concern is Mother Nature. If we experience too many cloudy days in a row; then we will need a backup source of energy. Perhaps it would be a good idea to explore the possibilities and fund th e research for solar energy before we deplete our backup resources.

The eNotes Blog How Reading Kafka Can Make YouSmarter
How Reading Kafka Can Make YouSmarter Got a big test coming up? Think youve tried every study tip available? Think again Heres one you likely havent heard of: read a short story by Franz Kafka before your exam and you may come out of it with an improved test score. The short story in question is a surreal work by Kafka called A Country Doctor. It was selected by post-doctoral researcher Travis Proulx (of the University of California, Santa Barbara) and Professor of Psychology Steven J. Heine (University of British Columbia) in their 2009 study specifically because of its absurdist elements. The hypothesis behind their research was that the exposure to a strange and unnerving stimulus would lead the brain to look for structure and order in any subsequent activity. The Method: The method of Proulx and Heines study involved exposing a test group to the surreal stimulus (in this case A Country Doctor) and then administering a grammar test to the group. The test was made up of an artificial-grammar learning task in which [subjects] were exposed to hidden patterns in letter strings. They were asked to copy the individual letter strings and then to put a mark next to those that followed a similar pattern. A control group was also tested; these subjects pre-test reading consisted of a substantially edited version of Kafkas text, which arranged the story in a more straightforward plot structure. Proulx and Heine labeled the surreal stimulus as a Meaning Threatsomething that fundamentally does not make sensewhile the absence of a surreal stimulus was categorized as having No-Meaning Threat. The Results: It was quickly apparent that Proulx and Heines hypothesis was correct; the test subjects who had been exposed to the Meaning Threat (A Country Doctor) not only found more patterns within the letter strings presented to them, but they were also correct in their findings more of the time than the test subjects who were not exposed to that surreal stimulus. ââ¬Å"People feel uncomfortable when their expected associations are violated, and that creates an unconscious desire to make sense of their surroundings.â⬠-Travis Proulx It turns out that the test subjects were so unsettled by the absurdism in Kafkas short story that their brains felt compelled to find order and meaning afterwards, as if to make up for the nonsensical nature of what came before it. So, how can this be applied to your studies? Well, besides reading A Country Doctor before a test, there are a number of other Meaning Threats you could apply to your life. You just have to understand what exactly a Meaning Threat is. You need something that challenges your very nature and the way you innately look at the world. When, for example, we think of fire, we instinctively associate it with heat. Now imagine placing your hand over a flame and feeling an icy coldness, the exact opposite of your expectations. Pretty disturbing, right? Thats exactly what a threat to meaning is. Meaning is an expected association within oneââ¬â¢s environment. A Meaning Threat is therefore something that doesnt make sense. When a committed meaning framework isà threatened, people experience an arousal state that promptsà them to affirm any other meaning framework to which theyà are committed. Exposing yourself to mind-opening (or mind-bending) works similar to Kafkas will spur you to find patterns and structure in other works. These can include the works of Surrealist painters, or certain movies,à like Blue Velvet by David Lynch or Un Chien Andalou by Salvador Dali andà Luis Buà ±uel.

History 101. Comparing facts and fiction in movies Essay
History 101. Comparing facts and fiction in movies - Essay Example Some of the main differences between the original Greek myth and the film is that based from the Greek myths, Zeus, Athena, Apollo, Hera, Aphrodite and Poseidon all played active roles in the Trojan War. In the movie it did not show the gods as existent or actively intervening. The impetus relationship between Paris and Helen making it catalyst for the entire war called the Judgment of Paris is not mentioned. In the movie, it seemed that the Trojan War only lasted for weeks when in fact it consumed 10 years of endless battles. Like any other historical tales and events such as Samson and Delilah or Cleopatra, the woman may be the cause of a man's demise. And if a man is too weak to resist the seductive advances of a woman, an entire nation can suffer same as what has been shown in the movie Troy. The huge army of the Persian Empire is sweeping across the globe, destroying every force that gets in their way. When Persian envoy arrives in Sparta offering King Leonidas power and control over all of Greece if only he will bow down to the wishes of the Persian King, Xerxes, the strong willed leader summons a small army comprised of his empire's best trained fighters and marches to battle. This act however futile is his way of saying that no Spartan King will bow down to foreign invaders. When King Leonidas together with his 300 Spartan men fell to the overpowering Persian army at the Battle of Thermopylae, the courageous actions of the noble fighters inspired all of Greece to defend their empire against their Persian adversary and wage the battle that would eventually give rise to the modern concept of democracy. In the actual Battle of Thermopylae, King Leonidas was joined by forces from other Greek city states having some 4,000 to 7,000 strong men under his command. 300 of those are Spartans being his personal bodyguards which was actually depicted in the movie. In the movie it was said that the downfall of King Leonidas is the betrayal Ephialtes of Trachis but in historical facts it is debated that it could be Onetas and Crydallus. One thing that can be learned from the movie is that no matter the odds, a man should know how to defend his people for the generations to come. In the quest to achieve this, only trusted and well-trained soldiers will ensure victory. Although there is strength in number but even a few but with stronger convictions can ensure success in some sense. References: (1) Pressfield, Steven.

GLADIATOR The death of Emperor Marcus Aurelius in the hands of his murderous and ambitious son, Commodus caused great chaos in the entire Roman Empire. One of the Roman army's capable and trusted generals, General Maximus Decimus Meridius is also the Emperor's key advisor. Even to his death, Aurelius decided to appoint Maximus temporary leadership of the empire and the enraged Commodus. He ordered the execution of Maximus and sends off the Praetorian Guards to murder his wife and son. Maximus escapes his execution but was severely injured. He was then captured and enslaved along the out borders of the Roman Empire. However, Maximus rises through the ranks of the gladiator arena to

Individual research and contribution Essay Example | Topics and Well Written Essays - 250 words
Individual research and contribution - Essay Example The first method involves survey whereby the consumers will interact directly with the researchers. They would be given questionnaires that are straightforward. They would be asked if they would prefer having the e-books than the actual book. In my opinion, other feasible research method would involve focus groups, which makes it possible for individuals to discuss the products among different groups of people. This makes it possible for the publishing company to understand the different perception of different groups. The research could as well involve personal interviews of writers and the readers. The publishers will have the creative minds of the writers who would likely be their clients in the future projects. I believe that responses from individuals might not give the clear interpretation of what the individual wants. This gives a good interpretation of the consumer behavior of individuals. Finally, the research would involve field trial where some of the books that have been published will be given to the consumers. This would make them understand some of the quality of the products from the

Symbols of Steinbeckââ¬â¢s Social Commentary Essays -- Literary Analysis
People in the 1930s were fighting a losing battle with themselves. They were approaching a depression, facing the eyes of war, and trying to stay on their feet with what little resources they had. Most were farmers and made a living by manual labor. The majority of what they owned, they made themselves. Such is the setting in John Steinbeckââ¬â¢s critically acclaimed short story ââ¬Å"The Chrysanthemumsâ⬠. In this story, Steinbeck set out to paint a portrait of what the conditions of the people were really like, but in a different light. Instead of focusing on technicalities, he focused on what the heart of America was going throughââ¬âthe struggles between what social standards expected and what individuals desired. In ââ¬Å"The Chrysanthemumsâ⬠, Steinbeck uses the characters Elisa Allen, the Tinker, and Henry Allen to exemplify the different personas of the time, and to reveal certain truths of society associated with each. Elisa Allen lives a peaceful life, but is fighting a constant battle with the prejudicial, parental society against her as a female. As Kenneth Kempton, author of Short Stories for Study, notes, ââ¬Å"whether it is freedom suggested by the nomadic life of the tinker, or children symbolized by her care of the young plants, or manliness as indicated by her delight in her strength and her masochist scrubbing of her body in the bath, or a normal sex life hinted at by her tenseness with when with her possibly impotent husband, or merely her lost youth as implied at the endâ⬠, Elisa is struggling inwardly. Beginning with a detailed description of the Salinas River Valley, which is enclosed in fog like a pot, the physical surroundings echo Elisaââ¬â¢s lifestyle. In fact, ââ¬Å"the chrysanthemum stems seemed too small and easy for her ene... ...n the ââ¬Å"bright directionâ⬠of the Tinker. Had the Tinker been better able to support himself, perhaps he would not have had to throw Elisaââ¬â¢s chrysanthemums on the side of the road. Opportunity, although presented to each of the characters, was never fully grasped, and so it remained, that ââ¬Å"fog and rain did not go togetherâ⬠. Works Cited Kempton, Kenneth Payson.

My Leadership Style Essay
Abstract Leadership is defined as a social influence process in which an individual seeks the participation of subordinates in an effort to research organizational goals. (Kinicki-Kreitner (p.346). My personal leadership style is based on the situational theory of leadership. Based on the type of situation my ability to adapt my leadership style is what makes me an effective manager. My Leadership Style Leadership is defined as a social influence process in which an individual seeks the participation of subordinates in an effort to research organizational goals. (Kinicki-Kreitner p.346) Being a leader in today environment is even challenging than ever. This is due to the pressure for increased transparency due to corporate greed, government pressure and individual corruption. There are great leaders throughout our history such as Martin Luther King, George Washington, and Jack Welsh. However, great leaders donââ¬â¢t have to be good. Barbara Kellerman notes that ââ¬Å"leaders are like the rest of us are: trustworthy and deceitful, cowardly and brave, greedy and generousâ⬠. (Kinicki-Kreitner p.346) Hitler, Mussolini, and Stalin are examples of great leaders that use their influence for their own personal gain. Kinicki-Kreitner states that ââ¬Å"to assume that all leaders are good is to be willfully blind (p.346). There are many different leadership styles and different leadership theories that individuals and corporations use. My personal leadership style is based on the Situational Theory. It is also transactional and adaptive compassionate and open. The situational theory of leadership is based on the effectiveness of a particular style of leader behavior depends on the situation. As the situation changes, so does the leadership style of the leader. As a retail manger managing 103 employees, my leadership styles changes on a daily basis. Things are always changing in this fast pace environment. Rules,à regulations, personal challenges, customer issues, are some of the many challenges that my managers and I face on a daily basis. I relate very well to Fiedlersââ¬â¢ situational model of leadership. His model is based on two factors. The first factor is that the degree which the situation gives the leaders control and influence is the likelihood the leader can successfully accomplish the job (Kinicki-Kreitner p.352). The second factor is based on how the leader is motivated. Is he or she motivated for accomplishment of the task or for close and personal relations? (Kinicki-Kreitner p.352) Based on these assumptions, my leadership style is based on build relationships. I value building relationships with people. I believe that building structured relationships with my employees will give them confidence in me and my ability to lead them. Making hard decisions such as hours reduction was easier to communicate to my employees because of the relationship that I built with them. They were able to understand and accept that this was necessary for the greater good of keeping the store open and profitable. This leads me to believe that I have a high amount of situational control within my environment. Situational control refers to the ââ¬Å"amount of control and influence a leader has in his or her environmentâ⬠(Kinicki-Kreitner p.352) There are three dimensions of situational control. They are Leader member relations, task structure and position power. I relate to all three dimensions with leader-member relations being the highest. Due to the relationships that I have built within my organization, I have the support, loyalty and trust of my assistant managers and my hourly employees. Leaders in todayââ¬â¢s economic and political conditions must me servants and not dictators. Robert Greenleafs servant-leadership approach emphasizes ââ¬Å"increased service to othersâ⬠through a holistic approach.(Spears p.1) Larry Spears in ââ¬Å"Practicing Servant-Leadershipâ⬠states that the ââ¬Å"great leader is first experienced as a servant to others work, promoting a sense of community, and a the sharing of power in decision makingâ⬠(p.1) Being a servant-leader is a approach that I use within my organization. By holding daily huddles and having my employees state their opinion on any issues allows them to feel involved in the daily operation of running the store. Having an open heart is also an important aspect to my leadership ability. Ronald Heifetz and Marty Linsky in ââ¬Å"Leading with an Open Heartâ⬠, states thatà if we ââ¬Å"lose our capacity for innocence, curiosity, and compassion. Our innocence turns to cynicism, our curiosity turns into arrogance and our compassion turns into callousnessâ⬠. (p.2) Being a leader in my organization is very challenging. However, the situation theory allows me to adapt to each and every challenging situation on a daily basis. Managing with an open heart and being a servant leader will allow me to take on any challenges without becoming a dictator or being resentful in the decisions that I make. The ultimate key to my leadership style is building relationships. Building structured relationships allows loyalty, respect and confidence that I get from my employees knowing that I will lead them in any situation. References Kinicki, A., & Kreitner, R. (2009).
