Sports And Money :: essays research papers

Anywhere you look today you can see Mark McGwire hitting a home run, or Kobe Bryant dunking over someone. Every time someone watches television or reads a newspaper these, and many other, athletes can be found. Professional sports are all around us; they're a part of our culture. But, in the last few decades some changes have started to take place. As the popularity of professional athletics has increased, so has the cost to render them and their players' salaries. Many of the contracts signed today are for millions of dollars. This is unreasonably exorbitant for doing something gaiety. These days sports are centered around money and not focused on the love for the game and entertaining the fans.   Ã‚  Ã‚  Ã‚  Ã‚  Some economists argue the point that major league sports, their products, players, and stadiums endow millions of dollars to our economy. This is true, but the 'fine print'; that goes along with it is often overlooked. Stadiums, for example, cost millions of dollars to build, maintain, etc. The funds to do this are provided by the tax paying citizens of that city. Many teams then, in return, relocate to other cities in search of more money and better facilities. This is no way to reward fans for years of loyal support. There are many programs, scholarships, foundations, etc. formed by many players and organizations though. These are good ways to give back to the communities that sustain them and use their grand salaries in a nice, resourceful manner.   Ã‚  Ã‚  Ã‚  Ã‚  Now the major appeal of playing in the 'big leagues'; is landing big contracts and getting endorsements; instead of a higher, superior level of competition. A prime example of this is Elton Brand, who bypassed his junior and senior year at Duke to go directly to the NBA. Another athlete looking for a big paycheck is Kevin Brown, who recently signed a $105 million dollar contract with the Los Angeles Dodgers. This is an outrageous remuneration for someone that plays a game. Not only are athletes overpaid, many ignore the rules of etiquette that come along with being in the major leagues.

The History Of Why Photovoltaics Environmental Sciences Essay

Energy security is one of the major challenges confronting world in the twenty-first century. It has been cited that about 20 % of the planetary population do non hold entree to electricity [ 1 ] . In add-on, it is predicted that the planetary ingestion of electricity will increase by about 50 % by 2035 [ 2 ] . For a sustainable hereafter, fulfilling the demand for energy should be accompanied with the decrease of CO2 emanations [ 3 ] by energy systems. Consequently, this brings about concerns in sing fossil fuels based systems as an option for fulfilling the turning energy demand. Renewable energy beginnings have been considered as being the solution for this uprising energy demand. Of recent, these systems have gained a batch of popularity and the energy coevals from renewables have been predicted to duplicate from 2010 to 2035 [ 2 ] . Harmonizing to some anticipations, renewables have the potency of catering for about one tierce of entire planetary electricity coevals by 2035 [ 1 ] . Photovoltaics ( PV ) is a rapid-growing market in the field of renewable energy, and this tendency is expected to go on in the close hereafter [ 4 ] [ 5 ] . Solar Energy is the most abundant and most every bit distributed renewable energy beginning worldwide. As such, PV can be considered as a major and the most promising renewable energy beginning. The advantages of PV over the conventional energy beginnings are listed below: PV systems are environmentally friendly ( C emanation free ) Solar energy has, by far, the highest natural and proficient potencies even for today ‘s engineering PV warrants long-run, care free, quiet and dependable year-round operation It can be operated as a grid connected system [ 6 ] or as an off grid system, supplying electricity even in stray parts [ 5 ] [ 7 ] Of class, these systems are accompanied with a few reverses. Main disadvantages of the PV are listed below: Large country demand Electricity coevals is limited to daytime ( it can non run at dark ) The cost of electricity generated from a PV system is still non comparable with fossil fuels, which indicates a trust on strong governmental policies [ 8 ] PV systems are classified into three depending on the photoactive stuff used and the degree of commercial adulthood: first-generation solar cells ( Crystalline Silicon ( c-Si ) ) , second-generation solar cells ( Thin Film Solar Cells ( TFSC ) ) and 3rd coevals solar cells ( Concentrating PV ( CPV ) , organic PV and fresh constructs ) . In general, an overpowering per centum of solar cells are fabricated from Si. First coevals solar cells dominate the current PV market with a portion of over 80 % of the entire PV market [ 5 ] [ 9 ] . However, 2nd coevals solar cells ( TFSC ) promise the highest possible for low cost fabrication and dependable energy beginning [ 5 ] [ 10 ] . Besides that, c-Si deficit which begun in 2005 and lasted through 2008 forced the industry to look for options, therefore the market for Thin Film PV begun to turn quickly [ 9 ] . Advantages of TFSC over wafer based solar cells are listed below: As the thickness of the semiconducting material bed is much dilutant in TFSC compared to wafer based solar cells, the recombination losingss are much less The fabrication cost of TFSC is well lower than that of wafer based solar cells [ 10 ] TFSC provides us with wider choice of stuffs compared to wafer based solar cells [ 10 ] , therefore bespeaking flexibleness of TFSC compared to c-Si solar cells However, surveies indicate that even with all these advantages the laterality of the c-Si solar cells will still stay for the coming 10 to 20 old ages unless a sudden addition in TFSC efficiencies is achieved in the close hereafter [ 9 ] , [ 11 ] . Undoubtedly, low efficiencies along with debasement over clip ( decrease in power end product ) are considered as the most influential drawbacks in the development of TFSC [ 5 ] , [ 10 ] . Surveies have shown that the levelized cost of the electricity ( LCOE ) generated by PV systems are extremely dependent on PV faculty efficiency [ 12 ] , therefore increasing the efficiency of PV systems has become an active country of research. Amorphous Si ( a-Si ) is one of the widely used stuffs in TFSC [ 9 ] , [ 13 ] . However, a-Si solar cells suffer from low efficiencies [ 14 ] which can be attributed to its set spread non being close to the optimal value ( around 1.4 electron volt ) . Besides, the thickness of the photoactive stuff in TFPV is normally really low which has a effect of take downing its light soaking up capablenesss. Extensive work on PV cells has besides been carried out over the old ages with a focal point on new stuffs and cell constellations [ 15-17 ] . Driving efficiencies up and/or cut downing cost, by technology stuffs for optimal belongingss and constellations have been the chief purpose of such researches ( ref ) . For illustration, a well-known agencie s of bettering the efficiency of a-Si TFSC is to replace a-Si with a semiconducting material like Gallium arsenide ( GaAs ) or Indium phosphide ( InP ) that has a close optimal bandgap [ 13 ] , [ 14 ] , [ 15 ] . Another attack is to implement a multi-junction solar cell [ 13 ] , [ 14 ] , [ 18 ] . However, besides those options, it is besides possible to better efficiency by heightening the light pin downing possible inside the cell [ 19-23 ] . The latter option is the chief focal point for this research. [ 1 ] IEA, â€Å" World Energy Outlook 2012, † 2012. [ 2 ] EIA, â€Å" Annual Energy Outlook 2012, † 2012. [ 3 ] G.

Summary Of The Lesson Of Life - 767 Words

Timmy Ginn Dr. Byington CE Composition I 08 March, 2016 The Lesson of Life â€Å"The most important thing in life is to learn how to give out love, and to let it come in† (Albom, 46). Life is a crazy thing. We are all thrown into it, are forced to experience it. Life is what we make of it. Two very intelligent men at the end of their life tried to convey this point. These two men live on through their teachings in Tuesdays with Morrie and Pausch’s final lecture. In these teachings two men follow the same essential theme, getting everything out of life. Despite that, the execution the two men chose are quite different. The most obvious difference between the two is the way their lives were ending. Both of them were reaching the end, but on very different paths. Morrie died of ALS, an illness that causes the victim to slowly lose the use of their body, leading to paralysis. But Morrie also had asthma, meaning once the disease reached his lungs he was done for. â€Å"The lump in his form was so withered that I almost thought there was something missing. He was as small as a child† (Albom, 163). While on the other hand Pausch was in almost perfect health. He could do push ups and run around. He was fit and seemingly perfect. But he had tumors in his liver that couldn t be removed. This meant even though he was healthy, he only had a few months to live. In addition, the way they taught their points were quite different.
