Advantages of using solar cells - Research Paper Example The environment has become a big issue around the whole world. During the last decade, it started to change quickly. The earth is becoming warmer and because of that, there are a lot of natural problems and disasters around the world.This is called global warming. People on earth caused this change in temperature. Further, people need energy in their daily lives. They need electricity, fire, hot water, heating and cooling. To produce energy that is enough for all of these activities, we need fossil fuels and coal. All the countries around the world use these two fuels to make electricity and to heat water or air. Many rich countries depend on countries in the Middle East to give them fossil fuels like oil and gas to be able to serve their people. Countries around the world have been using these forms of energy production almost for a hundred years now. The people on earth are increasing every day, and their needs of energy are also increasing. The price of making energy in the old wa ys is also becoming higher and higher. In the past, the effects of the use of fossil fuels and coal were not known. However, we now know what we are doing to our world and to our future generations. Therefore, we have to do something to change this. Many countries and governments have started to look for new technologies for energy production. These new energy technologies should be good for the environment. They should not make our problem worse and they should be cheap. One of the new energy technologies is solar energy.... For instance, nuclear plants, which are referred to as a clean source of energy by some people, produce waste that is very harmful to human beings and the environment. The United States actually faces a serious problem because there are no facilities to store and process nuclear waste. This will be a problem in future as more and more nuclear waste is stored in the nuclear plants themselves. Coal fired plants also produce ash waste that is very dangerous to the health of human and animals. Some of this waste was used in the past to produce building equipment, but these products were found to be harmful as well. Moreover, even hydro plants can make problems for the wildlife and put waste into rivers and lakes. On other hand, solar cells only use sunlight to produce power. There are basically no byproducts or waste from the solar plants. The only waste may be in the form of damaged solar cells. However, the damaged solar cells are usually reprocessed to produce new cells. For example, Doug Smock wrote â€Å"Solar Plane Takes Flight† in 2010 in Design News to show the first solar airplane. The author shows how the airplane was built using over ten thousand solar cells to power it and reduce waste from fossil fuel airplanes (Smock 45). This is an example of how solar cells can be used as an alternative clean energy source as compared to fossil fuels. In addition, pollution from the old energy sources has become an important issue of debate as many scientists have confirmed that our planet is warming very quickly. Solar cells give a good solution to the issue of pollution because they produce no emission into the air. â€Å"Solar energy is one of the cleanest energy resources that does not

The Function of Performance Management Article Example | Topics and Well Written Essays - 2250 words

The Function of Performance Management - Article Example Performance management decides the basis for the future business activities and the processes that have to be given the proper budgets as well as the resources on the part of the organization. The business process reengineering (BPR) aspects are in line with how these divisions are made in the quarter of the performance management functions and boundaries. For the human resources tenet, the role of performance management is all the more vital since it has to devise ways and means through which different activities are sequenced in terms of importance, vitality, etc. Thus it is important to state here that the role of performance management does not end here, though its basis might just lessen a little bit in the financial and different departments that we consider our attention upon. However within the realms of the human resources division, the importance is made more and more essential since employees need to be appraised time and again about their performances and functioning. What this performance management system does is to ensure that the right people get the bonuses, incentives and so on as well as point out the ones who have fallen short on the company's expectations over a period of time. This would help in giving them rewards and incentives which will eventually make one and all happy at the end. Also this will continue their desire to achieve more and more within a specified period of time and thus come into the good books of the company. In return, they can be given all these rewards so that they could be encouraged in line with their work attitudes. Moreover, the people who lag behind with regards to their work schedules and dedication levels will stand up and take notice and thus would want to be counted as the effective and efficient ones within the company as well. The role of organizations in the maintenance of these systems is also very paramount. The difference from the annual appraisals and so on lies in the fact that the traditional manner of doing things relies more on the basis of paper work where a lot of time, effort and money is rather wasted to state the least. The role played by the organizations in advancing their performance management systems is immense since a lot of the population depends on them for their needs and wants. This is met in a fair manner courtesy the E-government initiative adopted by several different companies and organizations. All such innovations which help and facilitate the related process must indeed be given thumbs up since these try to solve the miseries of the people and it is because of these people that the performance management systems are put into place originally. This further pinpoints the fact that the deployment of an efficient performance management system policy within the organization would indeed help it to essentially tackle its internal issues in a better and more effectiv e manner possible. There is a lot of growth potential for the sales force to be automated in the business to business environments since performance management systems are in place, more so because the business to business scenarios boost a trend of interaction in between the channel members no matter which marketplace they hail from. This could either

The Parental Influence On Children Young People Essay

The Parental Influence On Children Young People Essay Though parental liability laws are creating a great deal of controversy, there is little doubt that parents exert a huge influence on children and their behaviour. One research proves that alcoholics were likely to have parents who were alcoholics, while domestic abusers were likely abused themselves as children. Academic and research literature contains a wealth of information tying parental influence to childrens behaviour. In the area of peer influence, for example, Chen et al (2007) note that, in a study among California and Wisconsin high school students, it was found that parental influence on peer affiliation still is significant even as parental involvement in adolescents lives diminishes. But it isnt only growing teens that respond to parental influences. Infants, even very young infants, respond to parental stress and react to it (Molfese et al, 2010). In fact, it has been revealed that parental stress and/or reaction can actually have an impact on vocabulary and cognitive development (Molfese et al, 2010). On the other side weve seen literature extolling the positive benefits of tools such as parental training on the success of children. For example, Sheely-Moore and Bratton (2010) discussed how a family-oriented, strengths-based approach toward working with lower-income African American families helped raise childrens grades while lowering school discipline problems. The authors in this study pointed to the need of positive parental involvement on childrens academic achievement and socio-economic development, though pointed out that parental involvement can be difficult for those who live in poverty (Sheely-Moore and Bratton, 2010). Furthermore, it has been proven that parental influence also has an influence on driving among their teenage offspring (Crawford-Faucker, 2009). According to the National Young Driver Survey (involving 5,665 students in grades 9 through 11) parenting styles had a definite impact on choices the young drivers made (Crawford-Faucker, 2009). The authoritative parenting style combining emotional support with clear rules and monitoring had a definite (and positive) influence on driving-related behaviours and other attitudes among adolescents (Crawford-Faucker, 2009). These teens had a lower crash risk, experienced fewer crashes as passengers and were twice as likely to wear seat belts as a driver (or passenger) then were teens with uninvolved parents (Crawford-Faucker, 2009). Furthermore, this group reported less alcohol use (Crawford-Faucker, 2009). But harsh verbal and physical discipline isnt necessary the way to go, either. McKee et al (2007) studied harsh verbal and physical discipline and child problem behaviours in a sample of 2,582 parents and their fifth and sixth grade children. The findings indicated that the harsh discipline was associated with child behaviour problems, with one dimension of positive parenting parental warmth helping to buffer children from the more detrimental influences of the harsher physical discipline (McKee et al, 2007). In this section that parents have a huge influence on their kids, whether those kids are tiny, helpless infants or defiant teenagers. Children tend to mimic their parents, for better or for worse. Some years ago, the organization Partnership for a Drug-Free America aired a series of advertisements showing a father breaking into his sons room, drug paraphernalia in his hands. Where did you get this? the father thunders. Where did you get this and how do you know about it?I know about it by watching you! the son cries out. I watched you do it! The point of the commercial, of course, is that children will take their cues from their parents. If parents act in a responsible manner and own up to a mistake or problem situation, children will take that same cue. If, however, parents are carelessness and put the blame on other people for their own mistakes, children will do the same things. Discussion The issue we need to address here, however, is that this is not necessarily a black or white scenario. Tyler et al (2000) point out that the parental liability laws, in which parents are charged with the crime committed by their offspring, could end up penalizing the poor. In a poor family, both parents might be working leaving their children to their own devices, simply because they cant afford child care. Furthermore, if a child is delinquent, poor people (at least, in theory) may not be able to afford counselling to find out the problem. Few people want their children to be delinquent (especially lower-income people). But then again, even among poor families, we find out that not all children are delinquent. What is the difference between the well-behaved children of poorer families and those who act out? One word: Parenting. Even if there isnt a male role model in the house, many times, the matriarch of the family takes a strict stance among her offspring, raising Cain if the offspring get into trouble. Furthermore, there are resources for parents of lower income families to find help for their children if there are issues. Though going through governmental red tape can be a hassle to find a counsellor, a community agency or even religious organization official can be of great help in an area such as this. The point here is that there is really no excuse for the parent not to get help if the child acts out.What about if the childs mother is little more than a child herself? If this is a situation of a teenage mother who doesnt know how to parent, the situation changes a little, but not a whole lot. The teen mother still needs to be penalized, and then needs to be mandated to attend parenting classes. Failure to do so is the teen moms choice and if the teen mom doesnt attend classes, this tells the law enforcement officials that her defiance could be passed on to her children. Poverty isnt a good thing and it makes things very difficult, especially as it pertains to the parent-child relationship. But to use that excuse not to charge parents for a childs conduct is passing on responsibility. Such a situation may serve as a wake-up call for not only the child, but the parent who is involved with the childs upbringing. Conclusion Parenting is not an easy job and there is nothing more frustrating than hearing from the school or from the police that ones child is in trouble. Furthermore, there are those who point to the fact that trying to manage an unruly team is tough, and its not the parents responsibility if the teen gets into trouble.But this isnt true. Weve shown, through the literature, that parents have influence on their teenagers, even if their teenagers dont seem to be listening to them. Parents who keep lecturing to their kids about the evils of drugs and alcohol abuse are likely to have kids who grow up disdaining both of those substances. However, if kids see their parents freely addicted in alcohol (or drugs), the kids will ask themselves why not? and go ahead do the same thing. Parental liability laws arent meant to be malicious, nor are they meant to beat up on parents. What they are trying to do is to help parents teach their kids some responsibility. Even parents in poverty stricken families have a choice as to how they raise their kids. If they make the wrong choice, and the kids break laws as a result, the parents need to be held responsible.

Winter in the Blood by James Welch Essay -- Native American Novels Win

Winter in the Blood by James Welch Winter in the Blood, a Native American novel written by James Welch, takes place on a cattle ranch in Montana, around 1970. On the surface, this is a story of a Blackfoot Indian sleepwalking through his life, tormented by visions, in search of a connection to his heritage. Welch's language is, at once, blunt and poetic, and the pictures it conjures are dreamlike and disquieting. Furthermore, the narrator of the novel is disheartened by the loss of his brother, Mose, and his father, First Raise ? the two most cherished people in his life. After struggling with guilt, sorrow, and alcoholism, the narrator overcomes these down falls through re-identifying with himself and his culture? specifically through the help of his grandfather, Yellow Calf.   Ã‚  Ã‚  Ã‚  Ã‚  In the opening line of the novel, the narrator provides a vivid description of the his decaying surroundings:   Ã‚  Ã‚  Ã‚  Ã‚  'In the tall weeds of the borrow pit, I took a leak and watched the sorrel mare, her   Ã‚  Ã‚  Ã‚  Ã‚  colt beside her, walk through burnt grass to the shady side of the long-and-mud   Ã‚  Ã‚  Ã‚  Ã‚  cabin . . . . The roof had fallen in and the mud between the logs had fallen out in   Ã‚  Ã‚  Ã‚  Ã‚  chunks, leaving a bare gray skeleton, home only to mice and insects.   Ã‚  Ã‚  Ã‚  Ã‚  Tumbleweeds, stark as bone, rocked in a hot wind against the west wall (1).'; Welch opens the story with this line to show a relationship between the narrator's feelings of worthlessness and the worthlessness of his environment. In addition, the author melodically begins the novel in a somber manner ? so the reader may immediately adjust to the tone encompassing the story.   Ã‚  Ã‚  Ã‚  Ã‚  The narrator continues with describing his resentment towards his home life, 'Coming home was not easy anymore. It was never a cinch, but it had become a torture (2).'; This excerpt provides the reader with an understanding of the sorrow that the protagonist feels at the beginning of the novel and throughout the first half. Further narration includes the protagonists feelings of distance from the land and blame that he places upon himself, 'But the distance I felt came not from country or people; it came from within me (2).'; Thus, as the reader, we understand that the narrator has removed himself from the land and his culture.   Ã‚  Ã‚  Ã‚  Ã‚  On the narrator's journey to find his girlfriend, Welch clearly demonstrates the overabundant use of alco... ...Yellow Calf and to ask him if he was ever acquainted with his 'grandmother'; (another twist: not old woman) (152). And, yes, Yellow Calf did know his grandmother and was able to provide the narrator with the missing pieces, of his grandmother's stories, that he longed for: that Yellow Calf is his grandfather and that he was the only one that treated his grandmother with respect after Standing Bear's death. Once the narrator realized this they,   Ã‚  Ã‚  Ã‚  Ã‚  'shared this secret in the presence of ghosts, in wind that called forth the   Ã‚  Ã‚  Ã‚  Ã‚  muttering of tepees, the blowing snow, the white air of the horses' nostril . . .   Ã‚  Ã‚  Ã‚  Ã‚  but there were others, so many others (159).'; It is then that the narrator completely absorbs the teachings from Yellow Calf, and allows his life to come full circle.   Ã‚  Ã‚  Ã‚  Ã‚  In the end, through the guidance of Yellow Calf, the protagonist discovers himself, learns to respect the natural order of the land, and overcomes the guilt and sorrow that has lived within him for many years. The physical journey may be complete, but the spiritual voyage will continue for a lifetime. Works Cited: Welch, James. Winter in the Blood ,New York : Penguin Books, 1974.

I had this mindfulness conversation with a friend I’ve had for a long time. I had the conversation at my house on the front porch. 2. How easy/hard did you find it to be mindful? Why? I find it very easy to be mindful this time one reason being that me and him knew each other since we were 12 and we connect like brothers and have a lot in common that’s why I can be so mindful to him. 3. What did you notice during the moments when you were able to be mindful? How were you feeling? I noticed while being mindful that we have so much in common and we shared so many memorys for so many years. I felt very good listening to him because we are so close and it felt good to listen to what he had to say at those moments. 4. How did mindlessness – both yours and the other person’s – show up in the conversation? What affect did it have? Our mindfulness showed mine at first because I was only listening to him then him to me. It affected us by letting us know we can both be mindful and listen and learn from each other. 5. What 2-3 things did you learn about mindfulness? I learned that when you listen to someone they can teach you something everyone has a different perspective and view and deserve to be listened to. Next I learned that when you stop and be mindful to someone they will in return most likely be mindful to you. 6. What would help you be more mindful in your life? Identify 2 actions (i.e. new behaviors you can practice). How will these actions improve your interpersonal effectiveness? One thing that would help me be more mindful would be to learn about that person find out what we got in common and listen to them and then tell them what we have in common and share that with them. If I did this more often then I would definitely improve my interpersonal effectiveness because when you are more mindful then people will do the same to you and when people are mindful to each other then they will get along better and can teach each other more things about each other and about life in general.

All Primary and Secondary Education Should Be Free Essay

Education is an important asset to any one’s life and should be available to every one of all ages. Certain levels of education should be available to people of different levels and should be easily accessible. We need a basic form of education in our everyday lives. If we did not learn simple arithmetic such as how to count or if we did not learn how to read, we would suffer in the real word. If we bought something, people could rob us of our change simply because we cannot count. We would not be able to learn if we cannot read. We would rely on pictures to describe things for us and to convey the message to us. We would lose the thrill of reading. All these basic skills are taught in primary school and everyone should have access to primary school education. It is essential that everyone goes to school and if money is what is stopping them, then the government needs to make a plan to help correct that. Primary education should be made free as it allows people to develop their brains and gain a basic knowledge of the world. The government should provide institutions which learners can attend to be educated which they currently do and they are called government schools. These schools should be subsidised by the government for people who really can’t afford school fees. If people have enough money and choose to attend a private learning institution and have to pay school fees, they should do that at their own will. School should be made compulsory from age six when children are able to understand and grasp concepts more easily until about the age of sixteen where they will have a broad knowledge of the world and can decide whether they want to further their studies in a more specialised way. The quality of learning should be of a good quality at all levels of education. Secondary education expands on the knowledge that learners have received from primary school. It is still a broad range of knowledge but more important knowledge is given to learners especially in terms of career choice paths. It should be free or subsidised by the government for people who are really underprivileged or who really can’t afford school fees. School gives children a basic knowledge in problem solving skills that they may need in their everyday lives. Secondary education is compulsory up until grade 9 since grade 10 is when learners choose specific subjects which they feel may help them later on in life or in the career they are interested in. School should be compulsory till the end of matric. It would keep young people off the street and they would be doing something constructive such as improving their education. Nobody wants to hire a sixteen-year-old which is the age you are allowed to leave school at. Those sixteen-year-olds end up jobless, sitting at home or can become involved in gangs or drugs. Instead of wasting their time, they should rather attend school. They choose not to go to school because they are lazy and need that push to make them do something. They stand a much better chance of getting a job with a matric certificate. Finishing school up until matric level also allows you to explore new areas in your life and so that you can help find yourself, your talents and your interests.
