Memory, Thinking, and Intelligence - Essay Example These are analytical, experiential and practical intelligence. The above listed behaviours for both academic and everyday intelligence fit into Sternberg's theory. Academic intelligence corresponds with both experiential and componential intelligence, as defined by Sternberg. Experiential intelligence essentially refers to the capacity to comprehend tasks, even novel ones, and execute them efficiently. In relation to academic intelligence, it references the capacity to assimilate knowledge, comprehend abstract terms and apply that knowledge, including the translation of the abstract into the practical. As regards componential intelligence, it essentially refers to problem-solving which, in itself, is predicated on the intellectual analysis of the problem and the selection of the optimal solution. In others words, insofar as the behaviours listed for academic intelligence ultimately derive from the capacity to assimilate and apply new knowledge, they correspond to Sternberg's theory of intelligence. As regards the behaviours listed for everyday intelligence, they correspond with Sternberg's experiential and practical intelligence.

The challenges of globalisation Essay Example for Free

The challenges of globalisation Essay Next offers an international delivery service to all there online customers this could be challenging for next to because if they give international customers an estimated delivery of their products they are completely relying on their curriers, and if the product does not arrive on the day that next said It would then next could get a bad reputation and bad reviews this will have a negative impact on the company and will discourage customers from buying online this means that next will see a decrease in sales. Availability Since Next went global there has been a huge increase in demand for next products this makes it hard for next to have all of their products available to everyone all the time, in fact it would be impossible so certain people will be forced to wait a long time for the product they want. However as long as next can make their products available to the majority of customers then they will not lose customers. Laws and regulations Laws and regulations would prevent Next from sending items such as lighters, sharp objects and electrical this could narrow the products that next have available for sale in other countries. Other laws that next may face are the import tax that they will have to pay on importing goods to and from countries. Language Language could be a barrier for some companies that want to globalise themselves, however for next a company which is such a big concern, their websites are available in every language that they sell in, this makes it easy for customers from abroad to purchase whatever they please from the next website. Customs Customs can be huge problems for companies. it could be problem for Next because when shipping long distance of the items could be delayed and this could impact the customers delivery date, this could give Next a bad reputation and have an impact on sales. Tax Tax will have a huge effect on next because every country has different tax rates the UK tax rate for value added tax is 20% and Spain’s 36.3% this means it is more expensive for consumers in spin to purchase next goods. Currency payments/security of payments Cultural sensitivity Next have customers all over the world, this could be a problem to Next because some of the items that they sell in UK stores may not be available in countries such as Dubai. Why is this? Certain laws and regulation will deter Next from selling goods that they know are much less likely to sell in certain geographic locations such as Dubai. In short Dubai’s culture frowns upon revealing clothes for example, women’s dresses with low necklines which would be perfectly acceptable in the UK, would be going against culture and even breaking laws in Dubai so it would make no sense for next to mass advertise this product however in the UK the dress could be a huge success and make next lots of money. In contrast there will be a minority of people that want the dress in foreign countries this can create a dilemma for next because the majority of shoppers worldwide would admit to switching shop if they cannot find the product they want or need. Keeping up with trends in other countries It is a challenge to keep up with trends in one country, however next has to keep up trends in over 70 countries, it is challenging because trends can change on a monthly or even weekly basis, so next cannot simply sell one range of clothing in every country because every country will have different demands so they must tailor their stock to there diffrerent target markets abroad.

Ir Spectral Analysis Of Oxovanadium Acetylacetone Biology Essay

Ir Spectral Analysis Of Oxovanadium Acetylacetone Biology Essay Complex will have ligand that will form coordination bond to the metal center by donating lone pairs of electrons to the empty d-orbital of the metal which is similar to the Lewis acid-base reaction. In this experiment, Acetylacetone and pyridine is the ligand will act as Lewis base and will be coordinated to the metal center of Vanadium, V, which is the Lewis acid. Acetylacetone is a ÃŽ ²-diketone that contains two alpha hydrogen atoms adjacent to the two carbonyl groups. As carbonyl-group is electron withdrawing group, these two carbonyl functional group will create an inductive effect which cause the alpha hydrogen to be more acidic and be easily deprotonated. Resonance stability of delocalising the anion formed from the deprotonation under basic condition also increases the probability of the deprotonation as shown in Figure 1: Figure 1: Mechanism of the deprotonation and delocalization of the alpha hydrogen Acetylacetone exist in both keto and enol isomer form as shown in Figure 2: Figure 2: Keto-enol tautomerisation of the Acetylacetone The enolate anion is able to act as a bidentate ligand as it can chelate onto the oxovanadium metal ion with the two oxygen atoms as the binding sites to form the VO(acac)2 complexes. Two acetylacetonate ligands are able to bind to the oxovanadium metal and form a square pyramidal complex. Addition of the pyridine compound will form an octahedral geometry complex. These can be further proven using IR spectroscopy where the different strengths, lengths and nature as according to Hookes law, IR absorption spectra is able to be unique for each complex. Experimental Procedure Preparation of VO(acac)2 The preparation of VO(acac)2 started with 5ml of concentrated sulfuric acid (H2SO4) slowly added to 5 ml of deionized water in a 50 ml round-bottomed flask. Then, 18 ml of ethanol and followed by 2 g of vanadium pentaoxide (V2O5) was added into the round bottom flask. The solution was refluxed in an oil bath for an hour. The mixture was then cooled and filtered using cotton wool. Subsequently, 6 ml of Acetylacetone was added drop wise to the filtrate. The reaction mixture was carefully added portion by portion to the solution that contained 7.4g of Na2CO3 in 120 ml of deionsed water in a 500 ml conical flask. The mixture was then cooled in ice water and filtered to obtain the dark green product. Product was dried under IR lamp. The product was weighted and percentage yield was calculated. Preparation of VO (acac)2py The VO(acac)2py was prepared first by dissolving 0.5 g of the VO(acac)2 products obtained in 20 ml of ethanol in a 50ml of round bottom flask. Then, the mixture was refluxed vigorously with 2 ml of pyridine for one hour which was then concentrated using rotary evaporator. Crystal of crude VO(acac)2py formed upon cooling in ice water which was then filtered and wash with 5 ml of ether. Product was dried under IR lamp. The crude dry product was weighted and percentage yield was calculated. The IR spectrum of product was then determined. Data Treatment and Analysis Calculation of Percentage Yield of VO(acac)2 The percentage yield was calculated using the following equation: V2O5 + 4H+ Æ’Â   2(VO)2+ + 2H2O + O2 -Reaction 1 2(VO)2+ + 2 acacH Æ’Â   2H+ + VO(acac)2 Reaction 2 Mole of H2SO4 used = Amount of H+ present = 0.0938 mol x 2 = 0.1876 mol Mole of acac used = Mole of V2O5 used = (limiting agent) The ratio of V2O5 and VO2+ is 1:2, Mole of VO2+ used = 0.0111 mols x 2 = 0.0222 mols As ratio of VO2+ and VO(acac)2 is 1:1, then theoretical mole of VO(acac)2 = 0.0222 mols Theoretical mass of VO(acac)2 = mole of VO(acac)2 x molar mass of VO(acac)2 = 0.0222 mols X 265.16 g/mol = 5.890 g Percentage yield of VO(acac)2 = Calculation of Percentage Yield of VO(acac)2py Mole of pyridine used = Mole of VO(acac)2 used = (limiting agent) VO(acac)2 is the limiting agent. The ratio of VO(acac)2 and VO(acac)2py is 1:1. Mole of VO(acac)2py = 0.00194 mols Hence, theoretical mass of VO(acac)2py = mole of VO(acac)2py X molar mass of VO(acac)2py = 0.00194 mols x 344.26 g/mol = 0.667 g Percentage of VO(acac)2py yield = Infra-red Spectroscopy Table 1: Summarized Data from IR spectrum of VO(acac)2py Important peaks observed in the spectrum of VO(acac)2 /cm-1 Important peaks observed in the spectrum of VO(acac)2py /cm-1 997.7 998.04 966.04 3449.72 Discussion Geometry of VO(acac)2 and VO(acac)2py Vanadium [IV] metal exists as vanadyl, VO2+ in aqueous solution. Before the reaction of the VO2+ with the acetylacetonate, VO2+ is coordinated to five water molecules and existed as octahedral geometry. However, acetylacetonate is a stronger ligand that displaces the water molecules. Since Vanadium is bonded to oxygen with a V=O bond, only 2 acetylacetonate will only be able to form coordinate bond with the vanadium central metal ion to form the VO(acac)2 complex with a square pyramidal geometry as shown in Figure 3. Figure 3: Reaction diagram of the coordination geometry of VO(acac)2 and VO(acac)2py The geometry of this complex is in the square pyramidal geometry instead of the trigonal pyramidal geometry is due to the steric effect caused by the acetylacetonate ligands. The geometry of the square pyramidal is to reduce the steric repulsion to the minimum with the optimal distance apart of the two ligands. Also, from Figure 3, it can be seen that there is a vacant coordination site on the principle z-axis available which allow another more coordination site if there is the presence of strong ligand such as pyridine in this experiment. Therefore, complexation occurred between the pyridine molecules and the VO(acac)2 where nitrogen lone pair in the pyridine molecules act as a Ï€- donor-ligand and strong Lewis base that donate the lone pair of electron to the VO(acac)2 complexes at the vacant coordination site. With the new VO(acac)2py complex formed having a distorted octahedral geometry due to the unequal bond length between the V=O bond and the V=N bond at the axial position of the vanadium metal centre which lead to asymmetry. Also, the octahedral geometry of the VO(acac)2py is a 6-coordinate complex that is of high thermodynamic stability. Shifting of the V=O stretching band The complex of the VO(acac)2 has an oxidation complex of +4 which the vanadium(IV) ion exists as a d1. Using the Crystal Field Theory, there is electronic repulsion between the electrons of the acac ligands and the electron on the vanadium metal ion which causes the initially degenerate 5 d-orbitals of vanadium metal ion to split into two different levels. The level with the lower energy has a t2g symmetry and consists of the dxy, dxz, and dyz atomic orbitals. The level with the higher energy has eg symmetry and consists of the dx2-y2 and dx2 orbitals. The difference between the energy levels is the ligand field splitting parameter, à ¢Ã‹â€ Ã¢â‚¬  o. In the octahedral geometry, eg orbitals are on the axial direction and are the most affected by the electrostatic repulsion which destabilize the orbitals and excite them to higher energy level. The t2g orbital is not on the axial position and thus, not much affected by repulsion and thus, stabilized and move to lower energy as shown in Figure 4: eg orbital à ¢Ã‹â€ Ã¢â‚¬  0 Energy dx2-y2 dx2 dxy dxz dyz t2g orbital Figure 4: Molecular diagram illustration of Crystal Field Theory As mentioned in the previous paragraph, the pyridine is a Ï€ donor ligand that binds to the VO(acac)2 complex at the vacant site at the axial position of the vanadium(IV) ion. The addition of the pyridine to the complex reduces à ¢Ã‹â€ Ã¢â‚¬  0 which this reduction of the splitting parameter was observed using the comparison of the IR spectrum of the VO(acac)2 and VO(acac)2py. From the spectrum found in Appendix 2, the spectrum of the VO(acac)2py complex can be seen that the V=O stretching frequency of VO(acac)2py complex is 32 cm-1 lower than the VO(acac)2 complex when the V=O stretching frequency decrease from 998.04 cm-1 to 966.04 cm-1. These reduces of the stretching frequency is proportional to the stretching energy of the V=O bond of the complex. The addition of the pyridine will result in the reduction of the stretching energy of the V=O bond. This shows that the V=O bond of the VO(acac)2py is destabilized upon the addition of pyridine to VO(acac)2. This can be shown using Hookes Law as shown: where v is the stretching frequency in cm-1, k is the force constant, ÃŽ ¼ is the reduced mass. The binding of the pyridine has decrease the force constant and the lone pair of the pyridine ligand is electron-donating which increases the mass of vanadium ion that result in larger reduced mass, ÃŽ ¼, which according to the Hookes law, result in lower stretching frequency wavenumber. The wave number is proportional to the amount of energy that is needed for transition where it highly depends on the ligand field splitting parameter. The shifting of the stretching frequency indicate that the ligand field splitting parameter has decreased in magnitude which the addition of the pyridine ligand has caused destabilization of VO(acac)2py complex. Similarly, the lone pair of electrons of the nitrogen in pyridine is added onto the anti-bonding of the molecular orbitals of VO(acac)2 complex. This causes the pyridine to be trans to the V=O bond. Also, this bonding of the electrons donated will increase the electron density of the vanadiums d orbitals which will decrease the p Ï€ → d Ï€ donation from oxygen atom to the vanadium atom in the V=O bond. This result in the falls of the bond order of the complex and the lowering of the bond strength which also lengthen the V=O bond length. Overall, there is decrease of energy need to stretch the V=O bond and thus lead to the shifting of the V=O stretching vibration to lower frequency in the spectrum. This also further proven that the VO(acac)2py has an octahedral structure. Also, there is the delocalization of the Ï€ electrons from the aromatic ring of the pyridine which able to stabilize the complex more and decrease the p Ï€ → d Ï€ donation from oxygen to vanadium in the V=O bond. This make the vanadium-pyridine complexation more feasible and stable that result in the stronger V-N stretching bond which gain partial double bond character. As a result of the inter-electron repulsion, the electron density of the V=O bond is then shifted towards the oxygen atom and cause the weakening of the V=O double bond that cause the bond to loses the characteristic of the double bond nature. Thus, lesser energy is needed to stretch the weakened and lengthened V=O bond and lead to the shifting of the frequency of the spectrum. There is also the reason of the trans influence where the trans influence is the effect of pyridine ligand that weakens the bond that is trans to itself in the complex. The electrons of the oxo-ligand in the axial position of the complex occupies the dz2 orbital that will cause new binding ligand to form coordinate bond with the vanadium ion to be trans position to the oxo ligand. Pyridine ligand have donate electrons to the VO(acac)2 complex metal center and reside in the 3dz2 orbital from the site trans to the oxygen atom which causes repulsion. Therefore, the pyridine ligand and the oxo-ligand are in the trans position to each other which uses the same orbitals on the metal vanadium ion for bonding. However, the oxygen atom cannot donate the electrons to the metal as well as the pyridine ligand which causes the V=O bond to be weaker. Therefore, both axial bonds to the vanadium are weakened and lengthened which decrease the force constant (k) and decrease the stretching frequency. The shift also helps to confirm the presence of VO(acac)2py. On the other hand, the VO(acac)2py spectrum found in Appendix 2 have showed peak of 998.04 cm-1 which has a small different to the 997.7cm-1 peak found in the VO(acac)2 spectrum. This shows that there is still presence of VO(acac)2 in the product. Also the literature value of the V=O stretching bond of the VO(acac)2 is found out to be 995 cm-1 which is close to the 997.7 cm-1 in the product spectrum. These further prove that the VO(acac)2 is present. This can explain for the relatively low yield of 58.5% of the VO(acac)2py synthesis as the reaction has not gone into completion. However, comparing the intensity of the peak of 997.7 cm-1 and 966.04 cm-1 which indicate V=O bond in VO(acac)2 and VO(acac)2py complex respectively, there is higher intensity of the 966.04cm-1 which show that more pyridine adduct is formed in product. This also shows that the reaction may be an equilibrium reaction where both product and reactant can be present. This result can also be interpreted as the reac tion is not complete and more reflux time or higher temperature for reflux is needed to carry out to ensure more products formed. Lastly, there is a broad low intensity peak at 3449.72 at the VO(acac)2py spectrum found in Appendix 2 which was due to the presence of water that may be caused by insufficient drying of the VO(acac)2py product. Observation of Color changes During the synthesis of the complex, there is a series of observation of color changing of the compound in the solution. The color changes observed during the synthesis of the VO(acac)2 is due to the change of the oxidation state of V2O5 (oxidation state of V = +5). The orange powder of V2O2 is being reacted with the H2O and H2SO4 to reduce to a dark green solution of [V(H2O)5]3+ (oxidation state of V= +3) complex during middle of the vigorous reflux. When the reflux is complete, the solution was in dark blue color which is due to the reduction of the remaining V2O5 to dark blue [VO(SO4)(H2O)5] complex (oxidation state of V = +4). During the forming of the pyridine adduct, the dark blue VO(acac)2 is changed to dark green VO(acac)2py complex. This color changing phenomenon can also be explained using the Crystal Field Theory mentioned. Electrons of the two different energy level orbitals can be excited with à ¢Ã‹â€ Ã¢â‚¬  o energy. The higher the oxidation state, there will be more different between the two splitting energy levels which therefore lead to higher à ¢Ã‹â€ Ã¢â‚¬  0. For V2O5 (oxidation state of V = +5) will have a higher à ¢Ã‹â€ Ã¢â‚¬  0 and hence will absorbs light of the electromagnetic spectrum of higher energy with higher frequency and reflect low energy light. Therefore, V2O5 will absorb the blue-green light of higher energy and reflect orange of lower energy light which is shown off as orange with naked eyes. When there is a reduction of the compound to VO(acac)2 or VO(acac)2py compound, the light absorbed was at lower frequency and light reflected was of higher frequency such as blue-green and thus, there is the change of orange powder to blue-green product. Therefore, VO(acac)2 and VO(acac)2py appe ared as blue-green compounds. Possible Limitations and Sources of Errors in Experiment There are several limitations of the experiment that result in not having 100% yield of the product of both VO(acac)2 and VO(acac)2py complexes. Firstly, there may be loss of product due to the cotton wool filtration that causes some of the filtrate to be trapped in the cotton wool and unable to pass through. Secondly, according to the Le-Chateliers principle, for the Reaction 2, if there is an increase in the H+ concentration, reaction will shift the concentration of the reaction to the left which result in lesser product produce. When the reaction mixture is added slowly to the alkaline sodium carbonate solution, incomplete neutralization may occur where not all H+ are removed, and hence lesser product is produced. Therefore, longer cooling time will be needed for re-crystallization so as to allow more crystallization of VO(acac)2 and push the reaction to the right. Another limitation is of using of the sulphuric acid, H2SO4 may result in the reduction of the VO2+ ions to V3+ ions which decrease VO2+ ions available for product of VO(acac)2 formations. The lower percentage yield of the VO(acac)2py may be due to incomplete refluxing and thus lead to low yield obtained. Also, impurities may be present in the VO(acac)2 product produced that observed at the bottom of the flaks which lead to false weight measured and inaccurate percentage calculated. The round bottom flask should be swirled every fifteen minutes during the reflux which can prevent the settling of the V2O5 solid at the bottom of the flask and identifying impurities. The yield of the VO(acac)2py can be improved with addition of excess pyridine and increase the reflux time. Possible Precaution in Experiment For the synthesis of the VO(acac)2 complexes, there is a step of the adding of ethanol into the mixture of solution for reflux. Ethanol was used as solvent. The metal vanadium atom is surrounded by non-polar ligands of acetylacetonate or pyridine in second part of the experiment. Ethanol is more non-polar than water and will form solvent-solute interactions with the complexes and dissolve those ligands for better interaction in the solution. The use of the ethanol also helps to separate the VO(acac)2 from the insoluble V2O5 residue that will be filtered and remain in the cotton wool during filtration. Also, ethanol was used to prevent side reaction that will arise so as to increase the yield of the product. From reaction 1, there is the reaction of the V2O5 and the H2SO4 to produce the intermediate VO2+ ion that besides reacting with the acetylacetonate in reaction 2, VO2+ can react with the water and oxygen molecules by-product formed from reaction 1. It is as shown in Reaction 3. The side reaction will decrease the amount of VO2+ available for reaction with the acetylacetonate in reaction 3 to form product of VO(acac)2. This will decrease the amount of yield of the product produced. 4VO2+ + 2H2O + O2  ® 4VO2+ + 4H+ Reaction 3 However, this side reaction can be reduced with the addition of ethanol where ethanol will react with oxygen and produce acetaldehyde as shown: C2H5OH +  ½O2  ® CH3CHO + H2O Reaction 4 Also, using vacuum to remove the oxygen and water formed can be a good way to reduce problem of side reaction with VO2+. Another precaution taken was adding drop wise of the acetylacetonate to ensure sufficient reaction time and prevent influx of the H+ concentration and shift the equilibrium to the left and decrease the yield of the product formed. Anhydrous sodium carbonate, Na2CO3, was dissolved in water so as to form alkaline solution to neutralise H+ ions so as to shift the acetylacetonate toward the enol form. This will increase the formation of the VO(acac)2 products. Also, the mixture solution was added slowly to the sodium carbonate solution so as to prevent the rapid foaming caused by the product of CO2 and lose of product due to overflowing. Also, slowly adjusting the pH with more alkaline environment and less mixture solution allows the reaction to react at steady pace and reduce any side reaction to occur. Conclusion The percentage yield of the product of VO(acac)2 and VO(acac)2py complex were 77.8% and 58.5% respectively. From the IR spectrum of VO(acac)2py, it is shown that the V=O bond have shifted from 9998.04 cm-1 to 966.04 cm-1. This shifting of the peak indicate the formation of the pyridine adduct, VO(acac)2py, with the decrease in the wavenumber of the V=O stretching band.

Tatparya and its role in verbal understanding :: Concept of Intention Sentence Papers

Tatparya and its role in verbal understanding I examine the concept of intention (tatparya) and its role in the phenomenon of verbal comprehension (sabdabodha) with special reference to Navya Nyaya, followed by some critical and evaluative remarks. An effort has been made to give an account of the apprehension of intention (tatparya) in four types of sentences: a) the ambiguous sentence b) the non-ambiguous sentence c) the vedic sentence and d) the sentence uttered by a parrot. I. The present paper gives an account of the concept of intention (tatparya) and its role in the phenomenon of verbal comprehension (sabdabodha) with special reference to Navya Nyaya, which is followed by some critical and evaluative remarks. In this connection, an effort has been made to give an account of the apprehension of intention (Tatparya) in four types of sentence: (a) ambiguous sentence; (b) non-ambiguous sentence; (c) vedic sentence and (d) sentences uttered by a parrot. II. The Naiyayikas have pointed out the philosophical significance of intention (Tatparya) first in the context of enquiring the seed of implicative meaning (Laksana). To them the non-realisability of intention or tatparya (tatparyanupapatti) is the seed of laksana i.e. implicative meaning. In fact, the implicative meaning of the term, ganga as found in the sentence gangayam ghosah is the bank of the ganga.. The primary meaning of the terms ghosah and ganga are ghosapalli and a particular flow of water (Jalapravaha-visesa) respectively. The milk-man-colony cannot remain in a particular flow of water and hence there is the non-realisability of the relation (anvayanupapatti) between them. This can be removed, if the bank of the ganga is taken as the meaning of the term ganga through laksana. In the same way, the implicative meaning of the term ghosah is also possible. In the former case laksana in the term ganga is accepted, but not in the term ghosah. In another, the reverse case is accep ted. If laksana is accepted in either of the terms, there will not be the non-realisability in respect of relation (anvayanupapatti). If it is argued that the removal of the non-realisability of relation is the result of laksana, the rule that the implicative meaning of the terms ganga and ghosah are to be accepted becomes meaningless. In reply, it can be said that the rule becomes contradicted if it is accepted that the removal of the non-realisability of relation is both the result and seed of laksana.

Sports and Drugs

Consider if steroids were legal, how much more exciting sports would be and t would be fair to everyone. Why: As an athlete and competing in a high level sport, I easily understand athletes and their reasons for doping in sports. At a high level you’re always striving to be the best you can be ad better than your opponents to win. Also, as a candidate for the Provincial and National Team for Canada I have experience in knowing what you need to know and expect while participating in these events.At a camp for team Canada, WADA showed up unexpectedly and took one of the girls’ urine test. So really this is why the topic of doping in sports caught my attention to is because I can relate to it and I’m interested in learning more about it. Why Illegal: it gives you an unnatural advantage against your opponent. Drugs or blood transfusions can provide a 5 or 10 percent advantage (Thomas Murray, Hasting report). Doping up your body and eliminating the concept of fair pla y is different from exceeding to your best abilities natural and being competitive.When participating in sports, it builds character to be determined, honest, and cooperative, but when an athlete pumps illegal performance enhancing drugs into their system it shows true character on what they would do just to win. It has a big effect on the athlete altogether. Doping also effects the psychological aspect of your morals and becoming a criminal by being dishonest and putting illegal substances in your body, it can be mentally damaging. Not only mentally damaging but doping messes up your body, the natural growth and development of it from unnatural drugs is something all athletes should be concerned about.Sacrificing your body to win isn’t a right way to compete. Most likely sport: From Peter Sullvan: The first overall highest percentage(3. 6) of positive illegal drug tests is cycling, in the 2006 tour de France( Including Floyd Landis in first) the top 5 placed athletes were al l guilty of drug use. Along with Lance Armstrong admitting to doping after winning 7 tour de France titles. Floyd Landis describes cycling as â€Å"Professional cycling is organized crime. † Coming in second not too far behind cycling is Weightlifting with a 3% average of positive testing.Seeing how these athletes need to lift mass amounts of weight, its almost predicted that this sport is top 5 for positive doping statistics. Turkey and Russia are common countries who’s athletes are accused of steroids. Thirdly, Boxing is a candidate for doping in sports with a 2. 9% average. A case in 2007 was where an anti- aging agency was distributing steroids to famous boxers such at Even Fields. Boxing requires strength and stamina and some feel the need to enhance their training with steroids to just be stronger than their opponents. Coming after boxing in fourth, is Triathlon.Athletes involved in this race are super humans, in perspective of many people. To run, swim and bike with out stopping is impressive and takes mass amounts of mental and physical strength. Lastly, Baseball makes top 5 sports in doping with a 2. 5% average in positive testing. Even though this sport isn’t in the Olympics, Major League Baseball players have been known for steroid use in the past of 1999 and early 2000’s, as well this past year 20 players got suspended for steroid use. Types: EPO (Erythropoietin): This is a method of an increase of blood oxygen.Erythropoietin is a natural hormone found in the human body. It revitalizes blood cells to have more oxygen, which then increases anaerobic activity. (Kelland, 2012). CERA(Continuous Erythropoiesis Receptor Activator): This is another form of EPO. It increases your blood oxygen level without having to inject yourself as often. Anabolic Steroids: This is a fake replacement of testosterone to help the body utilize protein allowing the athlete to train with more intensity, along with building muscle mass and strength easier. Another aspect is that it acts as an anti- inflammatory to recovery quickly.  (Kelland, 2012)Diuretics: A substance that can mask illegal substances so they wont be detected.

(Kelland, 2012) Gender? : Which gender is most likely to dope in sports? Well males are a dominant factor for doping. They are much more likely to dope in sports by using steroids. Steroids effect women in a much more negative effect then it does to men. For women, steroids have side effects such as growing hair in unwanted places, clitoral enlargement, and deepening of the voice.T’s easy to tell when a women is taking steroids because of the testosterone over load in their body and manly features. Their physical, behavioural and functional part of the women’s body are out of natural sync as well. Why would women want to take steroids in the first place? other than getting very strong? Women want equality and by taking steroids they can feel equally strong as men in the same playing field. Who’s in charge? the name is WADA (World Agency of Anti Doping). This organization keeps it fair throughout sports.The Olympic committee wanted an agency like this for all countries to follow to specialize on key activities include scientific research, education, development of anti-doping capacities, and monitoring of the World Anti Doping Code and it was quite a success. A cool fact is that WADA’s headquarters is right in Canada, Montreal. Their objective is to have a doping free sporting environment. Consequences: As an Olympic athlete it is important to keep your body clean of illegal substances. Why? Some of the consequences are quite serious.If caught by WADA (The World Agency of Anti Doping) before the Olympics, he/she is suspended for 6 months or longer. (Freedman, 2012) If an athlete has cheated during an event, and won, their medal is taken from them and the results are re-evaluated. Conclusion: In conclusion doping in sports is a serious social issue that shouldn’t be taken lightly. Doping shouldn’t be seen as a way to make an athlete feel better. Not only are they cheating themselves, but they are unfair to their opponents and should take into consideration what mental and physical harm they are really doing to their bodies.WADA is a great service to help deal with keeping sports all around the world fair by testing athletes for performance enhancing substances in their bodies. As an athlete myself I choose to really look into this topic because I’ve dealt with WADA myself. If you are an athlete, beware of what you put into your body. Its important to train to your full potential without being artificially enhanced with chemicals. The natural way is the way to go! Most important thing learned was how harmful steroids can be to your body and mind. Always important to stay true to yourself and not cheat. Be the best you can be

Free Essays on David Levinsky

INTRODUCTION Published in 1917, The Rise of David Levinsky is considered to be the first American novel to chronicle the Jewish American immigrant experience at the end of the 19th century. Almost a century later, it can be difficult to imagine the significance of this book at the time of its publication and in the intervening years. Certainly before the turn of the last century, and undoubtedly since, we are proud to proclaim our nation a country of immigrants. We have developed an awareness of the immigrant experience through a variety of media- newspapers, books, magazine articles, television documentaries, radio shows and movies. We hardly can help but be aware, to some degree, of the unique challenges that have faced immigrants from such diverse places as Vietnam, Mexico, Cuba, China and Korea, to name a few. Even over the last thirty years within our own Jewish community we have come to appreciate the experiences of Russians, Iranians, Israelis, South Africans and South Americans starting their lives over in their adopted homeland. What became the book The Rise of David Levinsky originally appeared as four related short stories in the English-language McClure’s Magazine. Immediately, what might have otherwise been available only to the new Jewish immigrants themselves, if it had been published in Yiddish, ultimately engaged a readership far beyond the streets of the Lower East Side in New York. The struggle for success, the challenges of building a new life while your heart lives in another continent, and the support as well as distrust that existed within the Jewish immigrant community were all laid out for everyone- immigrant and American alike.

And Then There Were None essay essays

And Then There Were None essay essays Is Justice Wargrave fair in killing all the victims? Justice Wargrave, the murderer in And Then There Were None by Agatha Christie, plans to kill all of the guests he invited to Indian Island. Since he judged all the guests to be guilty of killing at least one person, they suffer fear and death at his hands.

Though quite a few of the guests do deserve their fates, several of them do not. Captain Philip Lombard, for ex...
