Evaluate the strengths and limitations of Employee Voice Practices for Essay

Evaluate the strengths and limitations of Employee Voice Practices for employees - Essay Example voice practices benefit employees by turning them into equal participants of the major organizational processes, letting them express their views and impact firms’ profitability and, eventually, turning them into essential drivers of organizational growth. However, the most important limitations of employee voice practices should not be disregarded. If not delivered properly, employee voice may lead to serious shifts in status quo which may not benefit employees. Many employees have the fear of such changes and, consequently, try to avoid the use of their legitimate voice in business practices. Therefore, one of the basic tasks faced by managers in organizations is to develop and run employee voice processes in ways that do not inhibit the employee’s right for self-expression and influence on organizational performance and, simultaneously, do not turn employee voice practices into a punishment for the things employees usually want to say. In order to understand how employee voice practices benefit or damage employee positions in companies, the exact meaning of employee voice needs to be understood. This is not an easy endeavor since the meanings and implications of employee voice are numerous, and different companies handle employee voice approaches in entirely different ways (Dyne, Ang & Botero 2003). However, across these numerous meanings, employee voice is generally assumed to be a motivation and willingness of employees to express their information, ideas and opinions regarding workplace improvements (Dyne, Ang & Botero 2003). Yet, it should be noted that if the worker does not express any opinions or does not try to impact workplace-related processes, that does not mean that this employee exists in the atmosphere of silence. In many instances, employees who withhold from expressing their opinions and thoughts openly simply use their voice in a different manner. Employee voice practices may be of a different nature and may also promote different forms of

Internet Protocol Security (IPsec) Research Paper

Internet Protocol Security (IPsec) - Research Paper Example In order to ensure security of information over the Internet various security technologies have been proposed that usually work on the higher layers of the OSI model and provide security in terms of authentication, confidentiality, integrity and availability. IPSec is one such security technology that operates on the IP layer and provides confidentiality, integrity and authentication. As it operates at the IP layer, its implementation provides security in the higher layers as well. And its implementation is such that the existing setup of Internet does not have to be changed in order to implement it. This report presents an overview of the IPSec technology. It discusses the general architecture of the technology, briefly covering its technical details and its operation modes. Furthermore the report discusses how IPSec can be integrated into the existing Internet setup. 1. Introduction The security of information is defined by four attributes; confidentiality, integrity, privacy and a vailability (Adeyinka, 2008). In the past, when computers were not that common a commodity let alone the Internet, virtual private networks were formed through installation of dedicated leased lines between the hosts e.g. networking of remote offices (Liska, 2003). Figure 1 Dedicated Leased Lines VPN Since these lease lines were private the information sent or retrieved remained within the related parties and so the communication was fast and secure. Thus private networks were formed. But the setup was costly and very few companies could afford it. Later on, in order to accommodate the mobile users, the companies installed dedicated remote dial-in servers (Remote Access Servers) that had modem(s) each connected to a separate dedicated phone line (Liska, 2003). Figure 2 Dial-up VPN Although the networking was achieved, yet the effort was not that useful as the speed of these networks was very slow. With the advent of the Internet and its global web servers that provided larger and ea sier access worldwide, the use of leased lines became an expensive burden and remained limited to very few resourceful companies. In view to the easy access to worldwide communication granted by the Internet, the element of security somewhat lost its significance and every other school, office, company and business sought out to be connected through the Internet. The instances of some serious cyber crimes (â€Å"Cyber Crime Stories†) led to the realization that the Internet is not at all secure. Being a public medium, the information sent across the Internet in the form of data packets passes through various networks until they reach their intended destination. Since the Internet protocol (IP) offers no built-in security, this plain text data in the IP datagram cannot be prevented from unauthorized access from the public network. Any third party can easily inspect, even modify or generate false data and compromise system security. For instance the passwords that are sent can be tracked and looked into (packet-sniffing), IP packets

The Benefits of Dance for Dyspraxics and Dyslexics Essay Example for Free

The Benefits of Dance for Dyspraxics and Dyslexics Essay As a consequence of my career in the teaching of dance, I have had some practical experience working with dyslexic and dyspraxic children for a number of years now and have become increasingly interested in the problems they face. In having this study to write an ideal opportunity arose to research the subjects in more detail. In doing so I have discovered how vast it really is and how difficult it is to write even an explanation of the conditions. â€Å"No two dyslexics are alike† ,[1] so how can one state precisely what it is? Even the different institutions who are expert in their fields differ. My aim is to open up the subjects, provoking some interest in the reader to learn more about them and then to focus on how I feel dance can be of assistance in the child’s life, albeit in very different ways. To cover just one subject thoroughly would be impossible, but I hope, in skimming the surface, I can demonstrate how important these issues are. I do not claim expertise. The information that I have used comes from reliable sources (see Bibliography) and includes personal opinions. The essential fact is that although the two words sound similar, they are very different problems. There are many definitions of dyslexia. The International Dyslexia Association states that;â€Å"dyslexia is a neurologically based, often familial, disorder which interferes with the acquisition and processing of language† .[2] British Dyslexics say simply â€Å"individuals†¦.struggle to learn through the medium of written or spoken language† ,[3] but have a list of definitions from other sources which includeâ€Å"dyslexia is the ability to see multidimensionally, all at once, or from any one place at a time. The ability to think in pictures and to register those pictures as real. Thus, you mix in creative thinking with reality and change what is seen or heard† .[4] The percentage of dyslexia sufferers varies from source to source, it may be up to 20% of the population (Dyslexia U.K information on ‘Incidence ’[5]) in varying degrees. That is a vast amount! Three times more males are affected than females probably because it is usually hereditary being passed down through males. In my experience boys heavily outweigh the ratio of boys to girls. Ron Davis, a dyslexic who suffered as a child wrote the book â€Å"The Gift of Dyslexia†. It left me both more confused about the problem and yet more understanding of it too! Why do dyslexics who are usually normal to above average intelligence often have difficulties at school even though hopefully nowadays teachers are taught to be more aware of learning disabilities? My understanding of Davis’ book allows me to see that dyslexics need a completely different teaching method because their thought processes are different. Dyslexics think in pictures, non-dyslexics think verbally (using words). These pictures/thoughts happen at a rate of approximately 32 a second, as opposed to 2-5 thoughts a second for the verbal thinker.[6] Dyslexics are not aware of most of their thoughts as they happen too quickly, but the subliminal part of the brain takes them in and it is this ability that gives them highly tuned intuition and creativity. They become so involved in their thoughts that these become reality- they see, hear, smell and feel what is in their heads. This causes me some confusion as I am a verbal thinker and it is difficult to conceptualise another way of thinking. How can any one teacher be expected to teach in two different ways at the same time? It is a little like having one half of the class thinking in French and the other in English but all speaking English (to use rather an extreme analogy). The reason behind thinking in pictures comes from the relative sizes of the brain’s hemispheres. The right side is often larger in dyslexics and this is the ‘picture’ side, the creative centre. The left side is the language side. This becomes a problem when the child goes to school and does not understand the written word. A different learning process is needed as our current methods rely heavily on written language and verbal thought. There becomes a big discrepancy between their intellectual ability and their reading performance. This lack of understanding in one area is also the reason why individuals are gifted in another area. Highly tuned intuition is a dyslexic talent, as is a greater curiosity the â€Å"dynamic force behind creativity† .[7] Dyslexics can ‘see’ things from all angles and from outside themselves. They can put their â€Å"mind’s eye† [8] anywhere, seeing the whole picture rather than fragments of the whole. â€Å"Dyslexia would not be so common if its effects were purely detrimental†. [9] Many of the great geniuses were dyslexic- Einstein for example once said, â€Å"if I can’t picture it, I can’t understand it† ;[10] Da Vinci, Walt Disney and Winston Churchill all suffered with this ‘affliction’. Living dyslexics include Cher, Whoopi Goldberg, Guy Ritchie and Eddie Izzard â€Å"the bizarre connections he makes in his unscripted shows may be a dyslexic dividend† .10 A recent article in the Daily Telegraph features a severely dyslexic entrepreneur, Ben Way who at 20 is a multimillionaire! His grandfather was dyslexic and his mother is which may be one reason for his exceptional skills. When he gets an idea he says â€Å"it all comes together like a whirring candy floss machine, turning in my head, making connections from all over the place. In an hour I find I can see the solution to a problem† .[11] He also says about people he has worked with of higher IQ than himself â€Å"but they don’t see things from so many angles†. 11 It is probably becoming apparent that the negative side of dyslexia has an equal and opposite positive side that would not be so developed if there were no dyslexia present. The way they think leads them to be potentially talented in many areas unrelated to their language skills. Their â€Å"special talent comes from the same mental functions that prevent them from being able to read, write or spell well† .[12] Intuition has already been mentioned, this ability to understand and picture the whole. Creativity relates directly to dance (and other visual subjects; art, design, technology etc). Their thought processes which allow them to picture something, even themselves from another point in space is highly desirable in artistic subjects. â€Å"Dancers and athletes (two favourite professions of dyslexics) ordinarily have their minds eye positioned above their heads† .[13] As babies and toddlers dyslexics are more curious than other children are, often walking before crawling. This curiosity leads to creativity and this creativity is the gift they have. In dance, imagination and creativity are vital. Dyslexics are usually good musically and inner rhythm is another important element we look for. In summary the abilities that dyslexics have that potentially would make dance a good medium are-1:Thinking in pictures; dance is a visual art form that requires the participant to see shapes and copy shapes. It is moving art. 2:Thinking and perceiving multi-dimensionally. All the senses are utilised, seeing the whole picture rather than fragments. Ideal when choreographing. 3:A vivid imagination. 4:Extraordinary creative skills. â€Å"Tasks which require the ability to visualise something in a creative or different way are often simple for the individual with these talents†.[14] Achievement is vital for anyone’s self esteem but especially for a child who may perceive themselves a failure in other aspects of their lives. To my mind if children are struggling at school for whatever reason, but find a niche for themselves in the dance class or any other activity, then we are obliged to nurture it. This should build their confidence and self worth and hopefully help them in other aspects of their lives and so prevent negative feelings of frustration and failure. It may also offset other related problems that could arise such as bad behaviour and depression. Thomas Scheidler (co-founder of The Greenwood School) discovered a â€Å"big discrepancy between their [dyslexics] ability to perform artistically and their ability to perform in language areas†. [15] In sports that needed good balance and co-ordination they excelled; dyslexics that are well co-ordinated â€Å"tend to also be especially good in sports that require balance and a sense of flow†. 14 It is so important to encourage children in disciplines where they demonstrate some aptitude, especially children who obviously suffer in basic learning areas. Dyspraxia or â€Å"developmental co-ordination disorder† is â€Å"an impairment or immaturity of the organisation of movement and, in many individuals, there may be associated problems of language, perception and thought†. [16] Between 2-10% of the population are affected, 70% being boys. (Dyspraxic Foundation). I intend to concentrate on the problem of co-ordination and only touch on other difficulties when they are relevant or link to the role of dance/movement. Almost from birth children with dyspraxia will show signs of movement impairment. They lack motor competence and have often been labelled ‘clumsy’. It is thought, †parts of the brain have failed to mature properly†. [17] Without delving into the reasoning behind this too much, it is noteworthy that when taking a ‘history’ questions concerning pregnancy and diet are included (p.19 Developmental Dyspraxia by Madeleine Portwood). Dyspraxia â€Å"affects how a child manages and co-ordinates his or her movements† [18] because â€Å"reinforced interconnections between nerve cells in the cerebral cortex are reduced in number†. [19] Normally automatic movements in the dyspraxic have to be taught and used repeatedly to create these connections. Dyspraxic babies often ‘bottom shuffle’ then walk because the brain can not give the limbs independent messages they need in order to crawl. Children display awkward movement, have limited creativity and concentration. They lack strength and tone in muscles and subsequently have poor posture. Each of the ‘skills’ we take for granted i.e. walking with co-ordinated arm movements, jumping, climbing etc, have to be learnt by the dyspraxic child. The neural pathways need to be reinforced quickly. It is the â€Å"execution of motor skills which encourages the development of the neural pathways in the brain†. [20] They find it â€Å"difficult to execute tasks which involve co-ordination of arms and legs†, 19 although they become good at a skill they have practised. Unfortunately it is specific to that particular skill and they find transferring information from one area to another difficult. They almost end up relearning the same thing to be used elsewhere. â€Å"Tasks requiring balance, rhythm and co-ordination are most useful†. [21] One of the single most important areas that dyspraxic individuals need to work on is their co-ordination and their gross motor skills. This word, co-ordination, has already come up and it and dance are synonymous. This is the starting point that makes me feel dance can really play an important part in a dyspraxics life and their subsequent development. Dance can help promote their gross motor skills, their balance, mastering common movements, for example, standing on one leg, hopping, hop scotch, skipping, controlling their arm movements and synchronising arms and legs. It will also develop the body’s postural muscles which will go a long way to assisting in the control of their body as a whole, making them more spatially aware of themselves. We use nursery rhymes with young children that require putting actions to words, these can be most fun and beneficial in learning to co-ordinate and move the body in a variety of ways (the teacher helping as needed). When the child goes from nursery school to reception there is â€Å"less opportunity to improve his gross motor skills† [22] and so attendance of a dance class will continue to improve and build on motor skills outside the school environment and in an enjoyable and more relaxed atmosphere. The dyspraxic child â€Å"will avoid activities essential for development if he is not directed towards them†. 21 If used alongside other intervention methods early enough, dance can enhance the child’s self esteem and teach the motor skills required to avoid physical conflict. This will encourage their peers to include them in activities and help them to feel less isolated. This is essential to the child’s welfare and may offset, like the dyslexic child, other emotional problems. It can be seen that the two conditions bear little resemblance to each other. A dyspraxic child can often have a reading age two years above themselves whereas a dyslexic will probably always find reading a chore. Dyspraxics have limited creativity but dyslexics show extremely high levels of imagination. A dyslexic is often very good at sports and balancing, co-ordination type activity whereas a dyspraxic has to work very hard to become as skilled. There are common areas though. Both generally have normal to high intelligence. Dyslexics will experience some degree of dyspraxia due to seeing their thoughts as reality and so losing their sense of space in actual reality, thus becoming confused and disorientated. In my experience both respond to routine and if this is upset it often leads to disruption and this will cause them to achieve less than when the routine is consistent. With a dance class repetition is necessary in order to acquire a skill. For a dyspraxic or dyslexic child to see what is ahead is reassuring, especially when they feel themselves improving. One last point of similarity and interest is that both affect more boys than girls. If we can entice many more boys into the pre-school dance class we can start intervention and indeed see the signs of a problem earlier. We tend by default to help more girls, either intentionally or unintentionally, simply because they present themselves in larger numbers. Learning basic movement skills and firing off imagination is important for both sexes, as is interacting socially in a controlled environment. If we could get the boys into the classes and into our imaginative world we could begin to help many more youngsters with or without learning difficulties. Dance to me has an obvious place here, whether it be tuning into an individuals talent and providing an outlet to a very creative mind, or giving a child confidence in moving their own body and having control over that body. I have experienced the positive effect dance can have in both these areas and seen children gain in confidence in other aspects of their lives as a result. Having studied these ‘disorders’ I feel I have acquired much more of an insight into the approach needed when teaching in this area and consequently greater confidence that using dance is a positive addition to intervention methods currently in use. In my opinion, dance is a world that should be open and enjoyed by all and be beneficial as a whole mind and body approach for a healthy life, emotionally, mentally and physically.

Basketball Case Essay Example for Free

Basketball Case Essay Introduction   Ã‚  Ã‚  Ã‚   Basketball, a game that was born in nineteenth century with the purpose to provide an â€Å"athletic distraction† to the students at the School for Christian Workers in Springfield, soon became a successful sport. More than 300 million people play basketball worldwide. The History of Basketball Invention and Rules   Ã‚  Ã‚  Ã‚  Ã‚   Basketball was invented by Dr. James Naismith, physical educator at YMCA Training School in Springfield, Massachusetts, USA.   He has four degrees in the diverse fields of Philosophy, Religion, Physical Education and Medicine. Naismith’s investigations in sports physiology and sports science helped him to create really successful game.    The concept of basketball was borrowed from the simple child’s game â€Å"duck-on-a-rock†, which involved attempting to knock a duck off the top of a large rock by tossing another rock at it. â€Å"James Naismith needed a game that could be played indoors in a relatively small space. The first game was played with a soccer ball and two peach baskets used as goals†. [1]   Ã‚  Ã‚  Ã‚   James Naismith devised a set of thirteen rules of basketball, through which you can look in enclosure 1 of this paper.   Ã‚  Ã‚  Ã‚   In 1959, James Naismith was inducted into the Basketball Hall of Fame (called the Naismith Memorial Hall of Fame.) Evolution of the game   Ã‚  Ã‚  Ã‚  Ã‚   Since invention basketball was greatly changed: Equipment. The early baskets were with the bottom and someone had to retrieve the ball. Later they were transformed into the metal rim with a net hanging below, and in 1906 people began opening the netting to let the ball fall through. The first basketballs were made from panels of leather stitched together with a rubber bladder inside. The molded basketball was introduced in 1942. Rules. Beginning in 1910 a player could dribble the ball, but could not shoot after dribbling. In basketballs early days, a players second foul would mean removal from the game until the next field goal was made. If a team committed three consecutive fouls, the opposition would be awarded a field goal. Beginnings in 1894 players were given a free throw when fouled. Beginning in 1908 players who committed five fouls were disqualified from the game. Based on the severity of the foul, the rules were soon amended so that players were awarded either two shots or one shot plus a bonus shot, which was attempted only if the first shot was made. The rules also determined that an offensive player could commit a foul by playing too aggressively.   Ã‚  Ã‚  Ã‚   In 1892 basketball was introduced to women by Senda Berenson Abbott. The rules of women’s basketball were modified (the court was divided into three equal sections, with players required to stay in an assigned area; players were prohibited from snatching or batting the ball from the hands of another player; and players were prohibited from holding the ball for longer than three seconds and from dribbling the ball more than three times.)   Ã‚  Ã‚   In May 1901 several schools, including Yale and Harvard universities and Trinity, Holy Cross, Amherst, and Williams colleges, formed the New England Intercollegiate Basketball League.   Ã‚  Ã‚   In 1915 the Amateur Athletic Union of the United States (AAU), the NCAA, and the YMCA formed a committee to standardize rules.   Ã‚  Ã‚   The first national collegiate tournament was held in Kansas City, Missouri, in 1937.   Ã‚  Ã‚  Ã‚   Professional basketball began in 1896 at a YMCA in Trenton, New Jersey. A dispute between members of the YMCA team and a YMCA official led to the players forming a professional team and playing for money. In 1898 a group of New Jersey newspaper sports editors founded the National Basketball League (NBL). The NBL consisted of six franchises from Pennsylvania and New Jersey. Stars of this league included Ed Wachter, who played in about 1,800 professional games, and Barney Sedran, who played on 10 championship teams in 15 years.   Ã‚  Ã‚  Ã‚   The first successful national professional league was the American Basketball League (ABL), which lasted from 1925 to 1931.   Ã‚  Ã‚  Ã‚   In 1926 a national tournament for women’s teams was formed. Notable players from this era of womens basketball include Babe Didrikson, Alline Banks Sprouse, and Nera White, who was one of the first two female players elected to the Basketball Hall of Fame. In 1938 the three-court game was changed to a two-court game, with six players on a team.   Ã‚  Ã‚   In the mid 1930s another National Basketball League (NBL) was founded and 1946 in a year of foundation of Basketball Association of America (BAA). Later four strongest teams in the NBL joined the BAA. Then the NBLs six teams also joined the BAA, forming a three-division league that was renamed the National Basketball Association (NBA).   Ã‚  Ã‚  Ã‚   In the late 1940s and early 1950s, the Minneapolis Lakers, led by center George Mikan and coached by John Kundla, won five NBA championship titles (1949, 1950, 1952-1954). In the 1950s guard Bob Cousy and forward Bob Pettit had the greatest individual impact on professional basketball.   Ã‚  Ã‚  Ã‚   For two decades after its founding, the NBA was the only major professional basketball league. But in 1967 the American Basketball Association (ABA) was formed. In the late 1970s, the NBA experienced a crisis of popularity but in March 1979 the public interest had revived.   Ã‚  Ã‚   In the late 1960s some rules in women’s basketball had changed: unlimited dribbling became legal, five-player team and full-court game became official.   Ã‚   The law called Title IX (1970s) prohibited discrimination on the basis of gender in educational institutions receiving federal aid, meaning that womens athletic programs had to be treated as equal to mens programs. In 1978 the AIAW championship was televised, and the same year a professional league called the Womens Basketball League (WBL) was founded.   Ã‚  Ã‚   Beginning in the late 1980s basketball became so popular that students began leave schools and colleges before graduation and go to NBA to play for large sums of money. So in 1995 the league enacted a limit on the amount of money a rookie could earn.   Ã‚  Ã‚   Following the 1997-98 season NBA owners and players could not agree on rules regarding a salary cap and several other issues, and the NBA owners instituted a player lockout. The dispute cancelled all league play until an agreement was reached in January 1999, resulting in a strike-shortened, 50-game season followed by a regular playoff schedule and championship series. NBA Legends 1950s and 1960s –     Bill Russell, Wilt Chamberlain 1980s – Larry Bird, Magic Johnson 1990s – John Stockton, Karl Malone, Michael Jordan, Scottie Pippen.    Records of NBA Highest score. 370 when â€Å"Detroit Pistons† defeated â€Å"Denver Nuggets† 13 December 1983.

The highest player  Ã‚   George Maureshan   from â€Å"Washington Wizards† has a height 2.31 meter. Conclusion   Ã‚  Ã‚   During more then hundred years basketball had greatly developed and changed, experienced a lot of difficulties, but it is still one of the most popular games in the world. Of course basketball as any other sport has a lot of problems today (e.g. U.S. team does not have a national program for international competition, devalues the World Championships and does not develop fundamentals), but it has a large potential and great future.       The Bibliography Laughead, George. â€Å"History of Basketball†.

The referee shall be the judge of the ball and decide when it is in play in bounds, to which side it belongs, and shall keep the time. He shall decide when a goal has been made and keep account of the goals with any other duties that are usually performed by a referee. The time shall be two 15-minute halves with five minutes rest between. The side making the most goals in that time shall be declared the winners.† [1]

Pros And Cons Of Solar Power Engineering Essay

Pros And Cons Of Solar Power Engineering Essay Solar power  is the changing or converting sunlight into electricity, either directly using  photo voltaic, or indirectly using  concentrated solar power  (CSP). Or, solar power is electricity generated from the level natural energy contained within the suns rays (solar radiation). Energy from the sun that is converted into thermal or electrical energy; the amount of energy falling on the earth is given by the solar constant, but very little use has been made of solar energy Commercial CSP plants were first developed in the 1980s, and the 354 MW  SEGS  CSP installations is the largest solar power plant in the world. The 80 MWSarnia Photovoltaic Power Plants  in  Canada, is the  worlds largest  photovoltaic plant. Experimental approaches to solar power include  concentrated photovoltaics  systems,  thermovoltaic  devices, and  space-based solar power. It is a versatile source of renewable energy that can be used in an amazing number of applications, providing power for everything from cars and boats to houses and spacecraft. Solar power is also clean and pollution-free. Solar power is an  intermittent energy source, meaning that solar power is not available at all times, and is normally supplemented by storage or another energy source, for example with  wind power  and  hydropower. People from all walks of life have benefited from the energy derived from the sun in one way or the other. History Human civilization has always used the energy of the Sun as far back as they have existed on this planet. Solar energy-power from the sun-is free and inexhaustible. The ancient Greek and Native Americans were the first to use solar power to their benefit, dating back as early as 400BC. Native Americans and the ancient Greek built their houses into the side of hills to take advantage of the heat storage from the sun during the day that would then be released during the night. The Romans took their knowledge of the sun being a source of energy as they were the first people to use glass windows to trap the warmth of the sun in their homes. While many people were benefitting from solar power it wasnt until 1776 that the first solar collector was built. This collector was built by a gentleman named Horace de Saussare. His collector was cone shaped and would boil ammonia that would then perform like refrigeration and locomotion. This first solar power collector attracted much interest in the scientific community through the 19th century.   In 1953, Calvin Fuller, Gerald Pearson, and Daryl Chapin, discovered the silicon solar cell. This cell actually produced enough electricity and was efficient enough to run small electrical devices. The year is 1956, and the first solar cells are available commercially. The cost however is far from the reach of everyday people. At $300 for a 1 watt solar cell, the expense was far beyond anyones means. 1956 started showing us the first solar cells used in toys and radios. The period from the 1970s to the 1990s saw quite a change in the usage of solar cells. They began showing up on railroad crossings, in remote places to power homes, Australia used solar cells in their microwave towers to expand their telecommunication capabilities. In the late 1950s and early 1960s satellites in the USAs and Soviets space program were powered by solar cells and in the late 1960s solar power were basically the standard for powering space bound satellites. Today we see solar cells in a wide variety of places. Recently new technology has given us screen printed solar cells, and a solar fabric that can be used to side a house, even solar shingles that install on our roofs. Applications of solar power The most obvious and realistic choice is solar energy, is important to adopt some kind of alternative source of power generation before we run out of current sources which produce electricity for us at present. Solar energy is available in abundant amount on earth and shifting our electricity requirements on solar energy is most likely to be the option in coming future. Solar plants have already start providing electricity to us on different levels and scales. Solar power gadgets or huge solar power arrays are seen producing massive amount of electricity for domestic and commercial areas. Solar power usage is not constant throughout the world. Developed countries more obviously have larger solar power consumption than developing countries. Solar Applications can be divided into three categories for understanding them better. Solar applications are available in sectors like Residential, Commercial, Industrial and Agriculture. Lets discuss these sectors in detail and know what work has been done in given sectors. Residential solar power : There are numerous solar powered based devices available in market which are used in residential sector, products like solar power heater, geezer, outdoor garden lights, battery chargers etc. These days entire homes can be powered by solar energy. Appropriate solar cells type is used and joined together in modules. These modules of cells are mounted on the roof of the home for direct exposure to the sun light. This sun light is then converted into electricity using solar cells and then transfer into electric system of the house. There are systems available which hold battery backups and store the access amount of energy. This energy can be used when conventional electricity is out. Industrial Solar Power : Solar energy is been in use in industry and provides multiple industrial applications, especially when power is required in remote locations. Solar power can be useful in such industrial applications where small kilowatt energy is required. Some examples of remote location solar powered applications are TV Station, Radio broadcasting towers, repeater stations, radio telephones etc. Solar power also facilitated electricity in transportation signalling system. Transportation system includes navigation systems, light houses in oceans, runway lights on airports, security camera in dark etc. Such applications where electricity load is high, solar power can prove cost effective by configure hybrid electric power systems, that joints photovoltaic solar power system with small generators that operates on fuel or natural gas. Solar power is highly reliable and can work on locations where conventional electricity is not reachable. Space is one of the examples for it. Satellites are powered by solar power from the day first when first satellite was launched in space Solar car is another most sophisticated application of solar energy. PV is installed on the surface of the car which converts sun light into electricity to power up a car. Such cars are not yet available for use in market, but they are bound to come for launch commercially very soon in future. Commercial Solar Power Commercial building like offices, school, clinics, community halls, hospitals etc can also take advantage from solar energy electrification. In office buildings, glass/glass PV modules can provide cover over atria, which provide shaded light inside the building. PV systems can also be installed on vertical wall office building in several ways, Curtain wall system, and rain screen over cladding etc. Advantages of solar power: There are countless advantages associated with Solar Power Energy. Uses for solar energy are not just for humans to take advantages from but it is amazingly useful for environment as well. Lets go through several advantages of solar energy. The major advantage is that the power that is derived from the sun is absolutely free and it will omnipresent as long as there is the presence of sun in this universe. The most unique and best feature of solar energy is its abundance in quantity available to our mother earth, if we use it to maximum levels it is not going to go anywhere until next five billion years. Solar energy plants are available for both small scale energy requirements and for larger scale energy requirements; it cops the market for both residential and industrial requirements. Solar energy can is easily be provided in rural areas where conventional electricity is not present already or it may cost more to setup electric grid station. It is cost effective to use solar energy generation methodologies in such rural areas. Solar power plants can also be connected to existing source of power generation to form hybrid system to boost energy requirements during sunny, hot and dry day. Solar power plants are normally very flexible. Solar cell modules or arrays comes in different shapes and sizes, it can be fixed on land or can be mounted on roof tops for maximum sun light exposure. Solar cell modules can also be fixed on glass skylights or vertical walls. Solar panels now come equipped with such devices which converts DC output from solar panels into AC for consumption. This way residential and commercial business owner can reduce their conventional electricity bills which are increasing day by day. Net metering is another impressive advantage of using solar energy. Net metering is term which refers to selling energy to conventional grid station in cases of excess production using solar panels. This way electricity bills are reduced by sending electricity back to grid station. Solar power panels are durable and do not require much maintenance, once in while cleaning of solar cell modules will be it. Average life time of solar power panels are up to 20 to 25 years, which justify the initial cost of solar panel. Solar power systems are soundless, efficient and without any pollution. Solar panels are capable of connecting with other type electric generators for instance gas turbines, wind, hydro etc. Batteries can also be charges for constant electricity supply. Larger solar power panels can help in meeting the demands of new power generation sources. These panels are easy to develop then other power generation plants. Solar power panels are very easy to expand, all is require adding up solar cell modules into it and it will start producing more electricity. Solar power systems are very friendly to environment and do not pollute it in anyway, they do not have any by product only electricity is produced. When solar electricity is used in place of energy generated by fossil fuels for meeting needs like lightening homes, office buildings, pumping of water etc, it will reduce amount of carbon-monoxide, greenhouse gasses and other pollution emitted into air. The more electricity from solar panels is used the more it is benefited for environment to reduce impurities from our atmosphere.  Ã‚   Solar electric system can be useful in employment through out the world. It has already benefited US economy by producing jobs in US solar electricity companies. The other major advantage of the solar energy and its systems is that it will last for lifetime and hence the homeowner will not be needed to shelve money from his pocket for the maintenance of these systems. We all should step ahead for solar electricity, create opportunities by exporting solar electric system to developing countries, reduce the usage of conventional electricity and protect global environment and reduce global warming phenomenon. Disadvantages of solar power: There are some disadvantages associated with solar electric systems.   Solar power panels initial cost is very high, this factor discourage solar electric system to spread widely and rapidly through out the world. Cost for solar panels may vary from location to location but estimated cost to run computer with other small electric appliances can cost up to 700 $ to 1000 $. Whereas to lighten up the entire house can cost 15000$ to 25000$ depending on the demand. Rural and remote areas which lack in conventional electricity are best suited for solar energy consumption but it solar electric system initial cost higher than using fossil fuels generated electricity. One other disadvantage of solar electric system is that they need whole lot of space of implant panels, sometimes on land and more often of roof top.   Solar panels are always require to directly face the sun to produce electricity constantly, if panels are not facing sun it will vary in producing watts. Since solar cells arrays and modules are exposed directly to the sun, different rays like Ultraviolet rays can slowly deteriorate the surface of the panels, dust, wind, and rain can also effect the over all performance of solar power panels

Shakespeares Portrayal of Henry V as the Model Monarch Essay -- Papers

Shakespeare's Portrayal of Henry V as the Model Monarch In this essay I intend to show that Shakespeare portrays Henry as the Classic Sovereign as he is patriotic, brave, cunning, religious, natural leader & in touch with the lower class of the country. I will use quotes and remarks in the play to show this and present it. I shall firstly do a summery of the play and give a basic image of what it contains, and then give a detailed analysis, which will give a more detailed view of particular scenes to show how Shakespeare shows Henry's character and finally I shall make a conclusion to present my evidence, to show that Henry is presented as a model monarch. The play is based around Henry V's later life after he has become monarch. He is shown in the plays forerunner Henry IV were he is a young prince he is shown as an insurgent young future king. He Drinks with a group of lowlifes from the criminal underworld of London and visits Brothels with them. However he is shown to have fitted into the role of King perfectly, and the play Henry V shows the most successful years of his life, in his campaign to gain France. The Chorus asks the audience to excuse the limitations of the theatre and to use their imaginations to conjure up the great events, which are to be presented in the play. ACT I. The Archbishop of Canterbury and the Bishop of Ely are anxious about a proposed bill, which would transfer a vast deal of the Church's property to the King. The Archbishop hopes that he may have averted this by the offer of a sizeable amount of money. We hear that the Kings disposition has significantly enhanced since he has come to the thron... ... military commander and avoids useless loss of life such as at Harfleur. In matters of state Henry is firm and decisive. His reply to the Dauphins "tennis balls"insult is angery but restrained and he listens to the advice of others. He dispences justice in a fair and impartial manner. The three traitors are condemned to death because they have threatened the safety of the kingdom and does not seek personal revenge & also has qualities which encoiurage us to believe in him as a human being, not just a paragon of kingly virtues. He has a sense of humour and is awkward and blunt when speaking to Katherine. I have done an Introduction, General summery, Detailed analyasis and a Conclusion and have put forward all my views and fulfilled the question criteria and have proven that Henry V is portrayed as a model monarch.
