Similarities And Differences Between Solar And Wind Environmental Sciences Essay

Similarities And Differences Between Solar And Wind Environmental Sciences Essay At present, human beings are living in a society which is developing rapidly, facing a severe crisis of energy. As the population is increasing in a high speed, the ecological environment has been damaged by human activity. At the same time, with industry highly developed, the environment has been polluted seriously. Therefore, other alternative energies should be found instead of fossil fuels, which is green, efficient and renewable. Thus, people began to discover the importance of renewable energy sources, for instants, solar, biogas and water. In fact, the majority of renewable energy sources come from the solar energy, which means they can be exploited for centuries and even millennia. In this essay, wind energy and solar energy are put in a comparison. Both of them are clean energy and environmentally-friendly, although they differ in cost and efficiency. The first important similarity of wind energy and solar energy is that both of them are renewable. Solar energy is the most abundant energy resources that human can make use of. It is estimated that during the past thousands of years the sun consumes only 2% of its own energy (Duncan, 2002). In the next few billion years there will not be significant changes to the sun, so the sun can be used as a permanent source of energy. Likewise, wind energy is also unlimited. Because it is generated by air flow on the Earths surface. Wind is everywhere, no matter it is in the vast grasslands or mountains. Wind power can be extracted by wind mills. As the wind makes wheels rotating, it is changing the wind power into electric power. Obviously, these two kinds of energy both come from the nature, which are totally recycled. Another similarity is that both wind energy and solar energy cause almost no pollution to the environment. Compared to the environmental effects of traditional energy sources, the environmental effects of solar energy and wind energy are relatively minor. Coal, oil and other fossil fuels emit harmful gases and residue, while the use of solar energy will not bring about pollution. Moreover, it will not produce any adverse effects on the environment, which is a clean source of energy. Meanwhile, after the extensive use of solar energy, the temperature will be slightly increased, although this temperature will not cause adverse effects on the environment and the ecological balance (Friis-Christensen and Lassen, 1991). Wind power consumes no fuels, and emits no polluted air. Wind energy is abundant, almost endlessly used, widely distributed and clean. Furthermore, both of them dont produce carbon dioxide, which do not cause the greenhouse effect. All in all, both of them bring peace to t he environment. In spite of these similarities, wind energy and solar energy are different in some aspects. At present, the use of solar energy technologies has the disadvantage of high cost. Topfocus (2007) stated that the cost of generating electricity by solar power is about 7-12 times higher compared to the normal electricity, and 6-10 times higher compared that of generating electricity by wind power. Furthermore, in many rainy areas with short period of sunshine, it is very difficult to completely rely on solar power supply. This means unless there are a large number of solar panels or there is a more sophisticated solar energy technology, it is still difficult to produce a large number of power supplies to meet the daily needs. In addition, solar panels have a limited lifespan, which is about 10-20 years. This means the cost to deal with the technical problems is extremely high (Brignall, 2010). In contrast, the wind turbines have longer lifespan, although it requires a lot of land to build. As long as the turbines have been built, it can be used for hundreds of years. In the short term, the base costs of wind turbines are relatively cheap. (Alvesta, n.d.) Another difference exists in the efficiency. Using solar energy is more efficient than wind energy. According to Duncan (2000), about 70% of sun energy can be received by the earth. In order words, more power can be collected by the solar panels. Furthermore, the materials used on the solar panels are silicon, which has less resistance in the power generation process (Ffbing, 2009). Compared to the solar energy, wind energy has short effective time and need to be built near the sea. When wind power is transformed into electric power, the efficiency is only about 20 % (Chapo, 2006). In conclusion, after comparing solar energy and wind energy, both of them have advantages and disadvantages. The solar energy solve the problem that human will not afraid there are no energy to use. However, the technologies still need to improve. Using wind energy is cheaper and more direct, although it needs high technology to be more efficient. At present, Chinas environmental pollution problems highlight the fragility of ecosystems. A large number of mining and the use of fossil fuels make a great impact on the environment, especially in Chinas energy consumption structure. The high proportion of coal, carbon dioxide emissions growing faster, which has a great impact on climate change. Development and utilization of renewable energy plays an important role in optimizing energy structure and protecting the environment, which reduces greenhouse gas and cope with climate changes. In my opinion, the renewable energy will play an important role in peoples life and let human have a bet ter future.

What do you learn about the First World War from your reading of :: English Literature

What do you learn about the First World War from your reading of Wilfred Owens poetry? From Wilfred Owens poems you can learn so many different things. He was one of a group of soldiers, he wrote about the war as he experienced it. So all of his poems are primary evidence because the poems were wrote by him when the war was going on. We can prove that Wilfred Owen was in the War by using a quote from a poem he wrote. The poem is titled 'Dulce et Decorum Est'. In the poem he gives his opinion on war. He says "Dulce et decorum est Pro Partria mori" This means it is good and beautiful to die for your country. He wrote it in Latin, the rest of the poem is english. By using Latin I think it creates a distinguished impact on the reader. It draws their attention to it. Honestly, Wilfred Owen does not believe it actually is good to die for your country. He is being critical. The opposition to this view of war would be a poet named Jessie Pope. Wilfred Owens and Jessie popes' poetry is very different, Jessie Popes' is usually more of a poem to recruit soldiers and get the point across that if you fight for your country war is good. Wilfred Owens poems are far more descriptive and appeal to the senses, giving us an insight on life in world war one. In the poem 'The Sentry' he appeals to the senses by describing the weather as "water falls of slime" and describing the smell "Stank old and sour." We can learn from this poem that physical conditions in the war were awful. There would be high danger of dying and injuring yourself because bullets were being shot everywhere and gas attacks were occuring frequently. "Gas! Gas! Quick, boys!"(From Dulce et Decorum Est) We learn how the gas attacks effect the soldiers in the poem 'Dulce et Decorum Est' there is a section in the poem where Wilfred describes a gas attack. "Dim, through the misty panes and thick green light, A under a green sea I saw him drowning." The misty panes were Wilfreds eyes; they were misted because of the gas in the air. He describes the colour of the gas as 'green' and the amount of it as a 'sea' so it spreads quite a distance and widths as seas are generally known for being large. Green is known as the colour of envy and maybe the gas is representing the opposisitions jealously towards the enemy that they are winning. In this poem Wilfred describes what the soldiers are like in their

The Effects of Printed Media on Gender Roles Essay -- Media Stereotypi

I will be looking at women’s 'to-be-looked-at-ness', and examining the representations of women as objects of the male gaze and male desires. In simple terms, a stereotype is the application of one (usually negative) characteristic to a whole group. The stereotype is an easy concept to understand, but there are some points you need to consider when looking at media representations with regard to stereotyping. For a stereotype to ‘work’ it needs to be recognisable to the audience and when so recognised, then judgements are made about the subject. If the stereotype is negative, then the judgements will also tend to be the same. The predictable thing about stereotypes is that they are predictable! They create a sense of order and also provide a sense of identity (even if it is a negative one!) Stereotypical judgements and stereotypical media representations can (and often do) lead to different treatments of groups by other groups, (sadly, often quite discriminatory). If we define ‘male’ and ‘female’ all we are doing is a biological classification, but if we think about the terms ‘masculine’ and ‘feminine’ we have to think about certain roles and lifestyles. Put simply, the words have very specific ideological assumptions of what is ‘natural behaviour’ for each sex. The portrayal of men and women in traditional roles is very prominent and also very contested in advertising. Characters, both male and female are constantly placed in roles, socially constructed to 'match' their gender. In other words, society has constructed (made) a set of ‘truths’ about what is the ‘right’ way for a man or a woman to behave. The media, of cou... ... adverts to highlight these changes. These reversals are, however, often portrayed in a sarcastic or less serious than in other adverts. Without these gender roles maybe society would have had an adverse effect on the media and what we portray as acceptable would in fact be outrageous. Why is the media so important? —One may ask. More often than not, it’s the way we get most of our information. Information we tend to think of as the â€Å"truth. Overall when looking at different types of media I got the general impression that women are portrayed in a worthless provocative manor. This was repeated in the same way across the whole range and always looked as if they were being exploited. Society have dictated to the media what they want to buy and see, all that’s left for the media to do is provide this product.

Level of Stress Among Call Centre Employees Essay

Level of Stress among Call Centre Employees Submission date: 8th January, 2008 Submitted By: Ayesha Khalid Ayesha Sarfaraz Nazool-e-Tabassum Saira Khan Mussaffa Butt Submitted to Dr. Farah Malik Associate Professor Department of Psychology Government College University Lahore Introduction Stress is used as a general label for a vast complex, interdisciplinary area of interest and study, much of which is health related. Most often stress is related to personal discomfort associated with an over demanding or distressinglifestyle situation (Adams & Bromley, 1998) stress is a part of everyday life, we experience stress each day, although it is acknowledged that the degree of stress varies considerably depending on the complexity of the situation and availability of support. For some, the stress is manageable and work or home life is not affected. For others, however, the stress reaches a critical point where there may be a need for medical or psychiatric assistance (Weiten, 2001). The causes of stress can include any event or occurrence that a person considers a threat to his or her coping strategies or resources. Researchers generally agree that a certain degree of stress is a normal part of a living organism’s response to the inevitable changes in its physical or social environment, and that positive, as well as negative, events can generate stress as well as negative occurrences (Frey, 2002). There can be innumerable stress factors since different individuals react differently to the samestress conditions. Extreme stress situations for an individual may prove to be mild for another,for yet another person the situations might not qualify as stressing at all. (http://www. lifepositive. com/stress. html). The fact that women report and exhibit higher level of psychological distress than men has been explained in three major ways. The methodological artifact explanation suggests that women are socialized to be more expressive and therefore will admit more emotional symptoms than men in response to the standard psychological stress (Frey, 2002). The stress exposure argument suggests that women face more stressor in general or more severe, persistent stressors than men. Whereas the vulnerability argument suggest that women lack coping resources such as high self esteem, a sense of mastery or appropriate coping strategies for handling the stressors to which they are exposed. Newman (1984 c. f. Eckenrode, 1991) suggested that women over report minor symptoms that inflate over all distress scores (Eller, 2000). Stress in humans in general results from interactions between persons and their environment that are perceived as straining or exceeding their adaptive capacities and threatening their well-being. The element of perception indicates that human stress responses reflect differences in personality, as well as differences in physical strength or general health (Frey, 2002). Stress is often termed asa twentieth century syndrome, born out of man’s race towards modern progress and its ensuingcomplexities. For that matter, causes such as a simple flight delay to managing a teenage child athome can put you under stress. Listing the causes of stress is tricky yet replete with practical diversity (http://www. lifepositive. com/stress. html). General cause of stress include primarily, Threat; a perceived threat will lead a person to feel stressed. This can include physical threats, social threats, financial threat, and so on. Fear; Fear leads to imagined outcomes, which are the real source of stress. Uncertainty; When people are not certain, they are unable to predict, and hence feel they are not in control, and hence may feel fear or feel threatened by that which is causing the uncertainty (http://www. workstress. net/causes. htm). Apart from certain general causes another reason is cognitive dissonance; it is when there is a gap between what people do and what they think, then the outcome experience is cognitive dissonance, which is felt as stress.

Mobile Phone and Social Media

There be days when I wish marathoner werent even Invented- to date I try to Imagine bread and butter with pop companion open media, and it makes me sad to realize how m each throng I would no longer be in contact with. The volume I communicate with the most on Faceable are not the race that Im closest to in disembodied spirit.

Consumer Behavior Essay

This section describes the roles of harvest-festival air in the process of consumer paygrade and choice. For this aim, literary works in the fields of point of intersection development, result concept, consumer behavior, marketing, and military personnel factors has been searched. The literature shows that the visual appearance of a ingathering provoke charm consumer point of intersectionion evaluations and choice in several(prenominal) ways. some(prenominal) authors considered the role of intersectionion or mail boat appearance in consumer proceeds evaluation or choice (Bloch, 1995 Garber, 1995 Garber et al. , 2000 Veryzer, 1993 Veryzer, 1995).However, they did not converse explicitly the different ways in which appearance influences consumer choice and their respective implications for overlap convention. In addition to these more novel contributions to the literature, the functions of a crossway in consumerproduct interaction be described in earlier industria l trope literature (Lo? bach, 1976 Pilditch, 1976 Schu? rer, 1971). Several of these functions concern product appearance. in that respect argon differences amid authors in the depend of roles (i. e. , functions) of product appearance they distinguish and the call they employment.For exercise, communication of ease of mathematical function was menti wizd by Bloch (1995) and was described as part of the artistic function by Lo? bach (1976), plot of ground Veryzer (1995) called it the communicative function of a product appearance. If all the roles mentioned in the literature argon considered as a whole, the following six roles of product appearance for consumers burn down be distinguished (1) communication of artistic, (2) symbolic, (3) functional, and (4) ergonomic product information (5) attention drawing and (6) categorization. A description of these six roles and their implications for product design follows. harvest-time Appearance and Aesthetic harvest Value The estheticalal regard as of a product pertains to the pleasure derived from seeing the product, without servant of utility (Holbrook, 1980). A consumer washbasin order the confront of a product strictly for its own sake, as looking at something beautiful is rewarding in itself. When product alternatives are similar in surgical process and price, consumers exit prefer the one that appeals the intimately to them aestheticalally (see, for example, Figure 1). Aesthetic responses are primarily emotional or olfaction responses, and as such they are real personal (Bamossy et al. , 1983).Several researchers return attempt to determine properties of products that are related to aesthetic appreciation. Innate preferences are proposed for visual formation principles, such as unity (i. e. , congruence in elements), proportion (e. g. , the Golden divide), and symmetry (Hekkert, 1995 ponderer, 2001 Veryzer, 1993 Veryzer and Hutchinson, 1998), and an inverted U-shaped relation is proposed between aestheticpreference and complexity (Berlyne, 1971). Another property influencing aesthetic judgments is semblance.The desirability of a annotate will shift according to the object to which it is utilize (e. g. , a simple machine or a table) and with the style of the object (e. g. , modern or Georgian) (Whitfield and Wiltshire, 1983). In addition to ( intrinsic) preferences for received properties of stimuli, prototypicality is effect to influence the aesthetic response. Proto typicality is the percentage point to which something is representative of a category (see in addition the section nearly categorization). In several studies, evidence is found for a unconditional influence of visual prototypicality on aesthetic preference (Hekkert, 1995 Veryzer and Hutchinson, 1998 Whitfield and Slatter, 1979).According to Hekkert et al. (2003), products with an optimal conclave of prototypicality and novelty are preferred aesthetically. As well as the product-rela ted characteristics previously mentioned, thither are cultural, social, and personal influences on design taste. For example, color preferences differ between tillages and in time (Whitfield and Wiltshire, 1983). In addition, personal factors, such as design acumen, prior experience, and record influence the design taste of consumers (Bloch, 1995).The influence of an aesthetic judgment on product preference great deal be moderated by the perceived aesthetic fit of the product with other products the consumer owns, or his or her family interior (Bloch, 1995). Product Appearance and symbolical Product Value Consumer goods carry and notify symbolic inwardness (McCracken, 1986). symbolical respect even can be the light upon determinant for product selection (Hirschman and Holbrook, 1982) and can account for the selection of products that clearly are inferior in their tangible characteristics (Levy, 1959).An example of the latter is Philippe Starcks Juicy Salif git squeezer (Llo yd and Snelders, 2003). The choice for a specific product or steel neatthorn have a bun in the oven the kind of person someone is or wants to be consumers use products to express their (ideal) self-image to themselves and to others (Belk, 1988 Landon, 1974 Sirgy, 1982 Solomon, 1983). Symbolic meaning can be attached to a product or dishonor on the basis of, among other things, publicizing (McCracken, 1986), country of origin, or the kind of quite a little using it (Sirgy, 1982).But the productitself also can communicate symbolic order in a more direct way, that is to say by its appearance. A products appearance communicates messages (Murdoch and Flurscheim, 1983), as it may look cheerful, boring, friendly, expensive, rude, or childish (see, for example, Figure 2). In addition, a certain style of appearance may evoke associations with a certain time or place (e. g. , the Fifties). Furthermore, the product or package appearance can reinforce the image of a brand, as the ident ity of a brand is convey visually in the appearance of products (Schmitt and Simonson, 1997).Consumers may attach the meaning of a brand to elements of the physical appearance of products. In this way, a brand image may enrapture to different kinds of products (see the section about categorization). many a(prenominal) companies on that pointfore make consistent use of certain design elements, such as a color combination, a distinctive form element, or style. For example, car manufacturers ofttimes try to keep different car models recognizable as belonging to the same brand. The distinctive radiator grill of BMW automobiles is an example of a recognizable design element.The linking of brand meaning to elements of the product appearance will be easier when the associations these elements engender by themselves (e. g. , because they are innate or are determined by culture) correspond to the desired brand image. For example, use of bright colour in and a bighearted size, which i s associated with aggression (Murdoch and Flurscheim, 1983), will make it easier to shoes a car brand as aggressive. Although there are large respective(prenominal) and time-specific differences in the experience of color and form, there are certain associations that seem to be relatively constant.Overviews of the influence of form and color on consumer perception of symbolic value (but also ergonomic and aesthetic value) can be found in Muller (2001), Murdoch and Flurscheim (1983), Schmitt and Simonson (1997), and Whitfield and Wiltshire (1983). For example, angular forms are associated with dynamism and masculinity, darn roundness evokes softness and femininity (Schmitt and Simonson, 1997). coating is an important determinant of the interpretations that consumers give and the associations they have with certain factors of aproducts appearance. For example, color associations vary from culture to culture (Whitfield and Wiltshire, 1983). In America and Europe, the color unobject ionable stands for purity, and brides traditionally dress in white in Japan itis a color of mourning. Furthermore, meaning is context dependent. The impression that colour in give may change completely by combining certain colors (Muller, 2001). Also, the meaning of forms and colors may change in time, as meanings are incessantly transformed by movements in art, fashion, etc. (Muller, 2001).There is some debate about whether symbolic interpretation is part of the aesthetic experience. In most literature, aesthetic value is mentioned as botha hedonic impression and a result of interpretation and representation (Schmitt and Simonson, 1997 Vihma, 1995). It is acknowledge in this article that whether a product is conceived of as beautiful is affected by what it represents (Vihma, 1995). The same style can be considered good taste at one point in time, while creation considered bad taste 10 eld later, because the connotations associated with it or the interpretations given to it h ave changed.For example, orange tree was a modern color for clothes, furniture, and pliable products in the Seventies, generally was perceived as old-fashioned and ugly in the Eighties, and became apply in products and clothing again in the Nineties. However, the view in this article is that aesthetic and symbolic value should be distinguished, as they may have opposite influences on preference. For example, someone who likes a colorful design may not buy it because it looks overly childish. Product Appearance and Functional Product Value

Gender Stereotypes Essay

Since theyre harmful gender stereotypes ought to become a priority.† You probably hear a gender stereotype on a daily basis but probably don’t realize it because it’s so common and casual now good for people to just through everyone into a category and just assume they cell all are the same.

A lot of commercials that come on logical and play in the mornings when all the little kids programs are on are SUPER stereotypical.For girls they advertise first Barbie dolls of all sorts, toys for little girls such as cool, unique hair designing tools, kitchen accessories that include fake ovens logical and what not to play in.

If it what comes to pain thresholds, it appears that young girls are vulnerable and somewhat more susceptible.It really actually (and excuse my language) pisses me off. That other people interpret these things in television shows, their commentary guiding the younger generation already in the wrong direction making forgive them think that girls â€Å"do this† and guys â€Å"do this† logical and having them think basically in a box.
