Renewable Energy Essay - 813 Words

Studyonlinenow Renewable Energy Is Only Part of the Best Way to Prevent Climate Change In our present life we are going through two of the main hazardous changes on the Earth, global warming and greenhouse affects. We want mankind to survive for a very long time, but if we keep using non-renewable energies the way we do, do you think we will be able to survive for a long time? I strongly believe that renewable energy is only part of the best way to prevent climate change. In this essay I intend to present a sound argument with a clear line of thought and relevant evidence. Of course there are times when renewable energy is not the best concept to prevent climate change. It has its†¦show more content†¦Renewable energy is as green as it gets as it is by today’s technical standards and it’s a marvellous method for fighting back against global warming. Fossil fuels are damaging the planet and this can be our way of doing something about that. The most important part is that renewable energy is commitment free and sustainable. It can be replenished s o we can use as much of this power as we need and we can restock it or it will restock itself. The sun and wind are with us for the long haul. As sources of power they are just waiting to be tapped for our future energy requirements all over the world. Even more importantly, renewable energy produces little or no waste products such as carbon dioxide or other chemical pollutants, so has minimal impact on the environment. Similarly, wind energy is friendly to surrounding environment, as no fossil fuels are burnt to generate electricity. Moreover, wind turbines take up less space than the average power stations. Wind mills only have to occupy a few metres for the base; this allows the land around the turbine to be used for many purposes, for example agriculture. As well as recorded in 2010, just in the Golf of the Mexico, more than 7000 birds, sea turtles and dolphins died because of the oil spills in the region.

Emotional Intelligence in Brave New World Free Essays

Emotional Intelligence in Brave New World In Aldous Huxley’s Brave New World, both the world and its people are designed to disallow deep feeling and passion. But, assuming the citizens of Brave New World are human, is it really possible for humans to exist as social, thinking beings without true emotion? What is emotional intelligence? For years people have been asking that same question. Emotional intelligence was first discovered in the 1930s by Edward Thorndike, but the term was still unfamiliar to the psychological world. We will write a custom essay sample on Emotional Intelligence in Brave New World or any similar topic only for you Order Now The term â€Å"emotional intelligence† was not officially used until 1985 by Wayne Payne (Cherry â€Å"Timeline of Modern  Psychology†). Today researchers still do not have an accurate description of emotional intelligence. In 1990 John D. Mayer was the first to describe emotional intelligence (EI) as â€Å"the subset of social intelligence that involves the ability to monitor one’s own and others’ feelings and emotions, to discriminate among them and to use this information to guide one’s thinking and actions† (Salovey 1990, pg. 185). Mayer and his research partner Peter Salovey further defined emotional intelligence as â€Å"a set of skills hypothesized to contribute to the accurate appraisal and expression of emotion in oneself and in others, the effective regulation of emotion in self and others, and the use of feelings to motivate, plan and achieve in one’s life† (Salovey 1990, pg. 210). Emotional intelligence is not only the regulation of emotions, but also the deregulation of emotions. The regulation of emotions is when we have control over our emotions. The deregulation of emotions is when there is no control over our emotions. The deregulation of emotions is greatly needed in our society because to be creative and to think outside of the box, one needs to let go of his or her emotions. To be passionate, our society needs to let our emotions run freely and flow without being restricted. Emotional intelligence gives that passion which encourages people to create our imaginative and our artistic society that we have established today. The question of whether we can live without deep emotion is also a question of whether we can exist without imagination. Emotional intelligence is a key ingredient in critical thinking. Critical thinking is the Rational reflective thinking concerned with what to do or believe, then critical thinking clearly implicitly implies the capacity to bring reason to bear on emotions, if for no other reason than that our emotions and feelings are deeply inter involved with our beliefs and actions. (Elder) In her article, Linda Elder gives the example: â€Å"If [a person] feel[s] fear, it is because [they believe] that [they are] being threatened. Therefore [they are] likely to attack or flee† (Elder). This shows how thought and emotions collaborate with each other to express our actions in difficult situations and in everyday life situations. Elder discusses how â€Å"it is critical thinking which provides us with the mental tools needed to explicitly understand how reasoning works, and how those tools can be used to take command of what we think, feel, desire, and do† (Elder). To effectively solve difficult problems â€Å"one must have the desire to do so†¦Thus the affective dimension, comprised of feelings and volition, is a necessary condition and component of high quality reasoning and problem solving† (Elder). If a person has a â€Å"‘defect in emotion and drive,’† that person can create a â€Å"‘defect in thought and reason† (Elder). â€Å"In short, the truly intelligent person is not a disembodied intellect functioning in an emotional wasteland, but a deeply committed mindful person, full of passion and high values, engaged in effective reasoning, sound judgment, and wise conduct† (Elder). â€Å"The emotions that you experience and the thoughts that drive them, like everything in the Universe, are at their core pure energy† (â€Å"The Power of Emotions†). Emotions are designed to help people become aware of their special needs. Without emotions, people would not know how to make decisions. Our bodies were made to make decisions based on our emotions. In her article â€Å"The Importance of Emotions,† Carla Valencia discusses how emotions are the most important factors in making correct decisions (Valencia 1-2). Valencia explains how positive emotions â€Å"not only motivate our existence, but also give enjoyment and happiness† to our lives (3). When we express â€Å"negative emotions, on the other hand, [it] impact[s] our lives in a negative way† (3). This affects our decisions because if we â€Å"take a decision when [we] feel revenge for example, the results could be dangerous. A negative emotional state leads to a negative behavior† (pg. 3). If people misuse their emotions, it can lead to wrong decisions. The different emotions that human beings feel are important for people to function as social and intellectual beings. In her book The Food and Feelings Workbook, Karin Koenig reveals that: The function of emotions is to tell us about our internal world, just as senses provide guidance in the external world†¦ emotions also] keep you safe and out of harm’s way, steer you toward what’s healthy and life-affirming, and deter you from what’s dangerous and life-threatening. (Koenig â€Å"What Is the Purpose of Feelings? †) Koenig believes that our feelings and emotions show people the â€Å"painful† and the â€Å"pleasurable† things, so that they can adjust and make proper choices (Koenig â€Å"What Is the Purpose of Feelings? †). In The Food and Feelings Workbook, Koenig argues that people â€Å"have a better chance at physical survival if [they] are biologically programmed to be highly sensitive to both pleasure and pain†¦ People] are also programmed for emotional survival† (Koenig â€Å"How Do I Know When I Have a Feeling or an Emotion? †). This explains why we need our different emotions to survive. Our bodies need feelings to affectively interact with our environment. In his book called Emotional Design: Why We Love (or Hate) Everyday Things, Donald A. Norman says that â€Å"affect is a vague sensation that may be either conscious or subconscious, but emotion is the conscious experience of such affect† (Norman 55). Emotions are not the result of a forced action; emotions occur naturally. Karin Koenig agrees with this statement by saying that â€Å"feelings belong to our primitive defense system and are rooted in our collective biology and the history of the species. They are neurological, biochemical reactions that happen on a cellular level in response to stimuli. They don’t require thinking† (Koenig â€Å"How Do I Know When I Have a Feeling or an Emotion? †). Emotions are used to differentiate the moral and the corrupt; the wrong and the right. We cannot survive without our emotions and feelings because our different emotions help us distinguish the good things from the bad things. Our emotions help us make decisions. Studies show that when a person’s emotional connections are severed in the brain, he cannot make even simple decisions† (Hein â€Å"Emotions- Importance Of; Management of Negative Feelings; Positive Value of†). People whose emotional needs are not fulfilled become depressed which usually leads to their death by committing suicide(Hein â€Å"Teen Suicide†). â€Å"Teenagers around the world are killing themselves to put an end to their intense emotional pain† (Hein â€Å"Teen Suicide†). Teenagers especially need their emotional needs to be fulfilled because they are at the point where they are developing their â€Å"emotional development† (â€Å"Emotional Development – Emotional Development During Adolescence†). Their â€Å"behavioral problems† are the result of their need to express their emotions (Hein â€Å"Emotions- Importance Of; Management of Negative Feelings; Positive Value of†). Our emotions are needed to help us make decisions, to help us be passionate about what we love, and to distinguish us from the rest of the world. We need our emotions to help us survive in this society, and without our emotions we are nothing but robots roaming aimlessly around the Earth. The stark reality of Aldous Huxley’s Brave New World is due to the lack of emotions from the citizens. Huxley’s â€Å"utopian† society fails because to have a rich existence in a society, one needs to express and have a full range of emotions. Huxley describes a dystopian society with â€Å"promiscuous sex, ‘the feelies’, and most famously of all, [the] supposedly perfect pleasure-drug, soma† (Pearce). Humans need their emotions to distinguish them from other humans. Their emotions and their personality create their own identity. If everyone was the same like the characters in Brave New World, we would not be able to function. We need our emotions to help us through difficult situations. Because the characters in Brave New World do not have emotions, they do not know how to handle difficult situations. Huxley falsely depicted a â€Å"utopian† society emotions and individuality. Huxley’s characters are not credible in that they lack the needed human emotion to make decisions, to create their own identity, to be creative, and to be mentally healthy. Lenina is one important character who is like all the other citizens in the way that she acts and in what â€Å"her† beliefs are. She is taught by the directors and World Controllers that â€Å"No pains have been spared to make your lives emotionally easy—to preserve you, as far as that is possible, from having emotions at all† (Smith). In Brave New World, the citizens do not know how to express their emotions because they are forced to be the same. If a person is different, like Bernard Marx, everyone criticizes that person. Bernard Marx is out of the ordinary and he â€Å"hated [Henry Foster and the Assistant Predestinator]† because they talk about â€Å"[Lenina] as though she were a bit of meat† (Huxley 45 ; 47). He respects Lenina and perhaps feels â€Å"love† for Lenina. This is unusual for an Alpha because they are injected with drugs when they are embryos so that they would not feel these emotions. The citizens are trained to have sex, and to take soma holidays. Bernard Marx is a defect so he actually feels and expresses his emotions which make him unique from the other people. Marx knows how wrong the â€Å"promiscuous sex, ‘the feelies’, and most famously of all, [the] supposedly perfect pleasure-drug, soma† is (Pearce). Linda is a citizen who was exposed to the outside world. Linda is forced to develop her emotions because if she does not, she will be considered an outcast to the â€Å"savages. † In Brave New World, Huxley demonstrates a false interpretation of a â€Å"utopian† society by stripping away the citizens emotions and feelings. In addition to being a false utopian society, this book falsely demonstrates how the world would be like without emotions and feelings. Steve Hein accurately describes what would happen without emotions. He says that â€Å"Our emotions help us make decisions,† and without these emotions we would be making wrong decisions which could lead to dangerous situations. We also use our emotions for critical thinking. The citizens in Brave New World do not have emotions; therefore, they do not have critical thinking skills. We cannot survive without critical thinking skills. Other than helping us make the right decision, our emotions make us unique. Without emotions, we are robots roaming aimlessly through the Earth.

Rear Window Scene Analysis free essay sample

A key element is the use of vectors, which are lines establishing contact between the two actors. There is a vector that connects Lisa and Jeff. When watching the conversation between the two, the viewer goes back and forth between the two. However, when going back and forth, Miss Torso can be seen because she is below the vector. The reason the vector is created is to get the viewer to notice Miss Torso in the background. Being able to see Miss Torso gives an example of something that Jeff sees. Another key element of this scene is the framing. The edges of the frame show Jeff and Lisa, but they also incorporate the opposing side of the apartment complex in the middle of the frame. We will write a custom essay sample on Rear Window Scene Analysis or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Even though the conversation between Jeff and Lisa is the main point of the scene, Miss Torso can be seen in her apartment in the middle of the frame. The ninety degree angle made by the beam in the window and the vector between Jeff and Lisa make Miss Torso the focal point because she is placed into the angle. Hitchcock frames the scene this way to put the viewer directly in the movie to let the viewer notice Miss Torso. The movie has a claim that Jeff’s neighbors have become a sight for him and something for his enjoyment. This can be seen by the fact that he uses all of his free time to observe what his neighbors are doing. The point of the scene is to put the viewer into Jeff’s apartment and let him experience what Jeff experiences on a daily basis. Hitchcock wants the viewer to notice Miss Torso because it is an example of what Jeff sees. Furthermore, Hitchcock wants the viewer to the see Miss Torso to do their own spying. Letting the viewer do their own spying makes the viewer more interested in what is going on in the background and more involved in what is happening in the movie. Finally, this allows the viewer to feel what Jeff feels such has his enjoyment when he is watching is neighbors or his terror when watching Lisa in the murderer’s apartment in later scenes.

Stern Mba Essays - Finance, Master Of Business Administration

Stern Mba Essays - Finance, Master Of Business Administration Stern Mba I like options, I like security, and I like power. With these wants, I knew at a very early age that I would enter business and thus I attended a college that specializes in the subject. In my first position out of school, I was hired by Dunhill Equities as a cold-caller. After several weeks of being hung up on by angry prospects, I decided that this career path would not lead me to success. I then moved within the firm to a position as sales assistant. While this was by no means my dream job, I learned a tremendous amount about business, and I gained useful exposure to the world of finance. Unfortunately, the company hit a period of instability, and after ten months I transferred with my boss to Coleman & Company. Thirteen months later, that company also began to fail, and I began to search for another path to advancement. With two strikes against me, I hit a home run and was hired by Sanford Bernstein into a challenging job with limitless opportunity for growth. After almost three years at Bernstein, I am once again seeking career advancement. My education and work experience have provided me with an excellent introduction to business, and they have sparked my interest in finance. Taking into consideration my foundation and my interests, graduate business school is the next logical step. At this point in my life, I consider a Stern MBA to be necessary since I need to gain a broader understanding of finance and to sharpen my analytical skills in order to be successful in corporate finance. Stern s MBA program will allow me to concentrate in finance, strengthen my global business perspective, and provide me with the opportunity to study with and learn from people with varied backgrounds. The school s location in the financial capital of the world and in one of the most diverse cities in the world also suits me perfectly. Aside from advancing my career, I would also like to develop personally. In college I did not join many clubs or organizations, and I did not participate in sports. Instead, I spent all my time studying, working, or dealing with family issues. Having been away from home and living in New York City for four years, I feel the need to make a name for myself and to develop a meaningful social life. I want to take advantage of the many benefits that extracurricular activities offer, and I want to be involved in the Stern community. Upon graduation from the Stern School, I will seek a position as an associate within the corporate finance department of a large, Wall Street, investment-banking firm. In three to five years, once I have become adept in financial analyses, drafting prospectuses, preparing business presentations and other financial advisory work, I will move into a senior associate position. Here I will develop my abilities to anticipate client needs and to engineer solutions that address these needs. In approximately 10 years, I will have the experience necessary to take on upper-level management responsibilities.

The Confidence In Of International Brands Dissertation

The Confidence In Of International Brands - Dissertation Example Figure 2: Age distribution in Saudi Arabia (male and female combined). Data sourced from Central Intelligence Agency The Saudi Fashion Market Western brands are very common in Saudi Arabia. Growth in franchising has been estimated at 27% in the Middle East in general, and in Saudi Arabia more than 70% of all franchised operations are American owned. Fashion from UK, Europe and the USA are all experiencing strong growth in the Saudi market, especially in the area of female fashion. While UK fashion initially had a strong hold over the market, there is now increasing trends towards US brands such as Gap, Gucci and Louis Vitton . The fashion market in Saudi is very seasonally based, with sales following religious holidays as well as the seasons. With the relatively young population, there is large potential for the fashion market. The habits of the nation are changing to become more in line with Western culture, a trend that is especially strong in the younger generation. Women are leav ing their traditional roles and many going into work. These trends are driving the boom in the fashion industry . Despite the fact that women wear the Abaya over their clothes, a traditional black dress that covers them, they often wear western clothing underneath . In addition there is a trend of fashion designers producing colored Abayas that are popular, especially for the younger generation. Teenage girls and young adult females have developed ways of wearing their Abayas that reveal their western clothing underneath, such as leaving the front wide open, or tying the edge around their waists, so their tight western jeans can be seen . There are also many different styles and cuts of Abayas and... While malls in Saudi Arabia resemble the western style of malls in many ways, but there is also strong evidence of the strict religious and cultural guidelines that are in place. Images on the front of music CDs are often censored, such as the sleeveless dress that Celine Dion wears on the front of one of her albums was replaced with a black shawl. Other differences are also noticeable, male and female Saudis are only able to work together in hospitals, so all sales people on the mall’s mixed floors are male foreign workers. At McDonald's the women must eat in a separate walled off section, while men eat in the open. The country has large segregation between men and women, so much so that paranoia about men hiding in dressing rooms has resulted in the absence of any dressing rooms in malls. The Kingdom Centre in Riyadh is attempting to turn this into a business advantage rather than a logistical hassle. They offer a female only floor, where all staff and security are female an d females are free to walk around in western style clothing, checking in their Abayas if they wish). Both products and sales are advertised in a wide number of ways, similar to in the western market. Internet advertisements are common, especially with the increasing use of the internet. Blogging has become a popular means of expressing the opinion, especially as media is tightly controlled. Because of this, flash and static advertising are common through blogging sites, although these are mainly for fashion stores in general.

Coefficient of thermal expansion ( CTE) laboratory Coursework

Coefficient of thermal expansion ( CTE) laboratory - Coursework Example Coefficient of linear thermal expansion (CET), denoted by ÃŽ ±, is indicative of how much a material will expand when heated. This expansion occurs as a result of increased vibrations of atoms owing of enhanced kinetic energy gained from the heat source. Consequently, the inter-atomic distance increases which ultimately causes the material to linearly expand. CET is an inherent property of material and plays a significant role during material selection phase for fabrication jobs especially where high precision and accuracy is required over large thermal gradients. Following table outline the consolidated results of the experiment. CTE using formula has also been calculated for each reading. Sample calculations are given thereafter. A graph for Extension (mm) against Temperature (oC) has also been plotted. 2) The large error in Aluminum up to 15558% is primarily due to human error. The readings may have not been noted accurately or the decimal place not marked in correct location. Systematic error can safely be ruled out since CTE of steel and brass and within acceptable error of 5.2% and 7.7% respectively 3) The slight error can be attributed to bias in noting down the temperature reading and extension precisely at the same time. Moreover, non-uniform heating, improper contact of temperature element and creep within the specimen due to multiple thermal cycles over time may have contributed to the variance in CTE. A dial gage itself is not an accurate device and electronic stain gages for measurement of extension can give more accurate results. The results comply with the values taken from ASTM Handbook for metals for both steel and brass. Readings for Aluminum must be verified since the large error can only be attributed to human fault. For per degree rise in temperature, aluminum expands most followed by brass and then steel. ASM International. "Thermal Expansion, Thermal Properties of Metals (#06702G)." ASME
