Effect of Creatine Supplementation

Effect of Creatine Supplementation Abstract Introduction The use of creatine supplements as an aid to enhance performance in sports shot to prominence after it was revealed that the British Olympic team had used said nutritional supplements in the build up to the Barcelona games of 1992. The Times (7 August 1992) reported that high profile athletes such as Linford Christie and Sally Gunnell had won gold medals while using creatine during their preparation. Although sometimes viewed as controversial by sections of the sporting community, creatine as a nutritional supplement is perfectly legal and its use is encouraged by certain sporting institutions. An example of this dilemma is within the NCAA (National Collegiate Athletic Association), whereby the distribution of creatine by team coaches is banned but individual athletes are still allowed to procure the supplement themselves, although the Athletic Management journal, among others, postulates that this was done in order to level the playing field rather than as a result of a side effect discovery (NCAA clamps down on supplements, 2000: 12.5). Creatine is a naturally occurring substance found mainly in meat and fish {{2 Herda,T.J. 2009; }} that was first isolated in skeletal muscle by Michel-Eugà ¨ne Chevreul in 1832 and given its name from the derivation of the Greek word for flesh, Kreas. Twelve years later, the German scientist Justus von Liebig theorised that this compound was necessary to produce muscular action in vertebrates after observing foxes in the wild and comparing their creatine levels to those in captivity. He even went as far as to harvest his own supply of creatine from the foxes and marketed it as Fleisch Extrakt, proclaiming that it would allow the body to do more work and for over a century this was the only creatine supplement ever produced. It has been established by the scientific community that increased ingestion of creatine as a dietary supplement will lead to an increase in the total creatine (TC) and phosphocreatine (PC) concentrations in skeletal muscle {{10 Finn,J.P. 2001;11 Harris,R.C. 1992; 14 Greenhaff,P.L. 1994; }}. PC is simply the phosphorylated form of creatine that is found mainly in skeletal muscle which is utilized during high-intesity exercise to quickly replace the diminished adenosine triphosphate (ATP) stores {{2 Herda,T.J. 2009; }}. This is achieved through the actions of the enzyme creatine phosphokinase (CPK) which is found in high concentrations in muscles, allowing for swift replenishment of ATP despite the rising levels of intracellular adenosine diphosphate (ADP) that occurs during exercise {{2 Herda,T.J. 2009; }}. Ergo increasing the bodies creatine stores should result in an improved ability to regenerate the skeletal muscle fibres ATP stores and consequently lead to improved performance a nd delayed onset of fatigue during bouts of high-intensity exercise (Hargreaves, M. 2006). The aim of this paper is to review the current literature regarding creatines supposed beneficial effect on muscle performance and determine what is the optimal method of delivering the supplement to the skeletal muscle. Since creatine became fashionable in the mid 1990s, numerous sports supplement companies have been researching how it can best be administered into the body, with regards to dose size, timing and the different forms of creatine now available. Other factors need to be considered such as potential side effects and certain population groups who may be at risk when using creatine. The general consensus is that it does work as an ergogenic aid; defined by Leuthholtz and Kreider (2001) as a technique or practice that serves to increase performance capacity, the efficiency to perform work, the ability to recover from exercise, and/or the quality of training thereby promoting greater training adaptations. Another aim of this paper is to examine the mechanisms behind creatine s beneficial effects and where these improvements take place i.e. specific muscle fibre types. It is also important to consider what is meant by improvement; does it mean performance in specific exercises or just in muscle development in general? Are there particular sports events where the improvements are marked and easily noticeable? The two enzymes required for de novo (endogenous) synthesis of creatine in humans, transamidinase and methyltransferase, are found in the kidneys, pancreas and liver {{18 Balsom,P.D. 1994; }}. Therefore creatine needs to be transported via the bloodstream to the muscles where it is needed and it has been found that the normal range of creatine concentration within plasma is between 50 and 100  µmol/L {{18 Balsom,P.D. 1994; }}. To determine the total amount of creatine in the body, the levels of both the free form (FC) and phosporylated forms need to be combined. The present day analysis is that for a man of 70kg, his TC will amount to approximately 120g, with a turnover (of creatine to creatinine, the break-down product of creatine phosphate in muscle) estimated at about 1.6% per day {{19 HOBERMAN,H.D. 1948; }}. This equates to about 2g in an average male, which is replaced by both endogenous and exogenous sources, the latter coming mainly from meat and fish as mentioned earlier, w ith herring being a particularly good example {{18 Balsom,P.D. 1994; }}. In 1986, Hoogwerf et al calculated that the average creatine intake in a mixed diet was 1g per day so the remaining gram has to be made up by endogenous synthesis, while those individuals whose diet lacks creatine completely due to insufficient animal produce intake, such as vegetarians or vegans, will have to make up their daily intake entirely through endogenous means {{21 Delanghe,J. 1989; }}. In terms of distribution, skeletal muscle is home to 95% of the TC found in the body, two-thirds of which is in the phosphorylated form {{18 Balsom,P.D. 1994; }}. The remaining 5% is found mostly in the brain, heart and testes. Ageing appears to have no effect on the total amount of TC found within skeletal muscles, but levels of PC were found to be lower in untrained elderly individuals compared to their younger counterparts, while FC was found in higher concentrations in the elderly cohort {{22 Moller,P. 1982; }}. A subsequent training study by Moller and co-workers revealed that once the elderly individuals had undertaken some basic exercise, their FC and PC levels more closely resembled those of the younger group. This points to a conclusion that inactivity will result in the dephosphorylation of creatine, a process that can easily be reversed by a return to training. A 1989 study by Tesch et al showed that type II muscle fibres have higher concentrations of PC than their type I counterparts, during resting state. These findings are to be expected since the anaerobic type II fibres use PC as their major storage fuel so that ATP can be generated quickly, as opposed to the type I slow twitch fibres that primarily use triglycerides as their main source of fuel. Before exploring creatines proposed effects on muscle performance and development, it is important to consider how its ingestion actually influences the bodies stores. In 1992 Harris et al showed that ingesting 5g of creatine monohydrate resulted in the elevation of the level of creatine in plasma, one hour later, from 50-100  µmol/L to over 500  µmol/L. Unfortunately the only research conducted that has uncovered the mechanism behind creatines transport from bloodstream into muscle was done in rats {{27 Fitch,C.D. 1966; }}. It was found that the intracellular trapping of creatine and a saturable process allowed for transport of the compound from the bloodstream across to the muscle and explained the high creatine content of the skeletal muscle. Perhaps surprisingly, this is still the most we know about this particular mechanism after over 40 years and is definitely an area that is prime for future research. Creatine monohydrate versus creatine ethyl ester While creatine monohydrates (CM) use is widespread, creatine ethyl ester (CEE) is less well known in the public domain. Manufacturers of the latter claim it is more readily absorbed into the body due to being more lipophilic and therefore having a longer half-life once ingested. It is converted back into creatine once digested as it is an ethyl ester derivative of creatine, specifically developed by the University of Nebraska Medical Centres technology transfer entity, UNeMed. The claims of the various manufacturers of this specific type of creatine were disputed by a study by Child and Tallon that was presented at the International Society of Sports Nutrition 4th annual meeting. They had found that CEE was quickly broken down into creatinine due in part to the decreased acid stability caused by the addition of the ethyl group (Child Tallon 2007). The proposed beneficial benefits of the two varieties will be discussed in length later on. Effect on body mass In 1975, Ingwall et al hypothesized that creatine could stimulate both cardiac and skeletal muscle into a state of hypertrophy by myofibrillar protein synthesis. In vitro and in vivo skeletal muscle had increased synthesis of the contractile proteins actin and myosin as well as the muscle specific iso-enzyme creatine phosphokinase, all of which were due to creatines selectivity. With the increased accumulation of these myofibrillar proteins, skeletal muscle went into a state of hypertrophy. This study is considered as the initial groundbreaking research into the methods behind creatines effect and a lot of the subsequent papers mentioned in this piece reference it extensively. Ingwall followed this initial study up a year later {{16 Ingwall,J.S. 1976; }} with a paper on creatines effect as a potential chemical signal that links increased muscular activity with increased contractile mass. An important factor to note is that this paper is not referring to creatine as a dietary supplement, as its effects as an ergogenic aid were not fully understood until the early 1990s, but rather as an end product of the contraction mechanism. Its aim was to establish the biochemical and physiological mechanisms by which muscular hypertrophy occurs after increased muscular activity and measure the effects of increased intracellular creatine levels in differentiating skeletal muscle cells in culture. The conclusion was that although creatine probably does play a role in selectively controlling the rate of synthesis of muscle-specific proteins, it is hard to determine whether these results would apply in vivo. There are two schools of thought when it comes to assessing the change in body composition that comes with creatine supplementation; an increase in fat-free mass, first proposed by Earnest et al in 1996, and/or an increase in the relative water content of skeletal muscles. Francaux and Poortmans found that after nine weeks of training and creatine supplementation, their was an increase in the absolute value of both total body water (TBW) content and intracellular water (ICW) levels but not the relative value, indicating that the gain of 1-2kg of total body mass they observed was due to dry matter growth {{17 Francaux,M. 1999; }}. These results were similar to those obtained by Kreider et al in 1996 in that there was an increase in total body mass without a change in the TBW percentage {{28 Kreider,R.B. 1996; }}. When specifically studying the effects of creatine ethyl ester (CEE) supplementation, Spillane et al found no significant changes in TBW between the CEE, creatine monohydrate and placebo groups after heavy resistance training lasting 48 days {{26 Spillane,M. 2009; }}. This study paid particular interest to the supposed water retention qualities of CEE as many of the manufacturers of the supplement claim that the esterfication process it undergoes increases cells permeability to creatine and minimizes the amount of extracellular water (ECW) retained during supplementation {{26 Spillane,M. 2009; }}. As suggested by Mesa and colleagues {{80 Mesa,J.L. 2002; }}, one of the potential benefits of creatine supplementation is the accompanied increase in TBW and ICW that help facilitate skeletal muscle hypertrophy. Furthermore in 1998 Kreider et al conducted a study that used bioelectrical impedance to evaluate the changes in body composition after short term (28d) creatine supplementation during training. They concluded that the increases in body mass that they found could not be explained by disproportionate increases in total body water content and the majorit y of the increase could be attributed to lean tissue accretion {{29 Kreider,R.B. 1998; }}. Powers et al study in 2003 is perhaps the definitive work done on the subject of water retention within muscle during creatine supplementation. They concentrated solely on the fluid distribution, in a similar way to Francaux and Poortmans; by measuring total body water as well as the intra- and extracellular levels and found that although water was retained, fluid distribution remained the same {{31 Powers,M.E. 2003; }}. The theory that water retention is the main stimulus for skeletal muscle hypertrophy due to preferential retention by the intracellular component is without any evidence in the literature researched for this paper. The increase in TBW is relative to the increase in total body mass, the majority of which is formed of fat-free mass. Effect on maximal performance Maximal performance can be defined in many ways depending on the discipline; within the gym environment it is known as the 1 repetition maximum (1RM), the most weight an individual can lift in a single repetition for a given exercise. Out on the athletics track, maximal anaerobic performance can be measured with a short sprint, between 60-120m for example. Most of the studies that will be subsequently mentioned in this section have sought to discover the effects of combining creatine supplementation with various forms and intensities of resistance training. The duration of the training period also varies from one study to the next. Beck et al combined ten weeks of resistance training with supplementation of a drink that contained creatine, amino acids and protein {{6 Beck,T.W. 2007; }}. The control group drank a placebo mixture that contained just carbohydrates, and both groups were tested for their anaerobic power production before and after training. Both groups experienced improve d performances in their leg extension and bench press 1RM scores as well as their muscular endurance (number of repetitions performed at 80% of their 1RM). Also of note were increases in fat-free mass and percentage fat reduction for both groups. Most significantly however, were the changes elicited by the test drink when it came to peak power (PP) and mean power (MP) production; quantitative values that were determined using two 30 second Wingate Anaerobic Tests (WAnT). A good summary of this test is provided by -zkan et al (2010): it requires 30 seconds of pedalling at maximal speed on a cycle ergometer, against a resistance that is determined by the users body weight. As mentioned, it tests the individuals muscle power, endurance and fatigability and these were all improved in the test group but not in the placebo group. Their reasons for using a combined supplement drink was to assess whether the creatine, protein and amino acids combined effect would be greater than the benefits that would be expected from ingesting just one of the ingredients alone. It was hoped that examining the changes expected in body composition after resistance training would help to differentiate between the mechanisms that assist in supplement-induced performance enhancement. In that respect the study revealed no new information. The combination drink did improve the test subjects anaerobic capabilities compared to the carbohydrate placebo but provided no additional benefit for improving muscular strength or endurance when combined with medium term resistance training. A possible improvement to the study would have been to add in placebo groups that were to consume just protein and amino acid isolate drinks and perhaps it would have then been easier to differentiate between the respective beneficial effects of each supplem ent. It does confirm that when exercising at near maximal level, increased PC levels within the muscle can be advantageous at replenishing the ATP-PC pathway in anaerobic conditions. A near identical study by Chromiak et al in 2004 had differing results when it came to comparing the final PP and MP values of the two groups {{48 Chromiak,J.A. 2004; }}. They found that those who had taken the carbohydrate-only drink had identical results, in respect to improved PP and MP values, to those who had received the combination one. Differing levels of training intensity and volume could account for these differences, as well as the fact that the test conducted by Beck et al was evaluated using two WAnTs, as opposed to the Chromiak study , who only used one. When the results are compared to other studies that have tested similar protein, carbohydrate and creatine mixes, creatine does appear to produce the most consistent improvements in performance related activities so one can assume that the isolated increases in PP and MP are due to creatine, rather than the protein or amino acids. Open to discussion however, is the possibility that protein and amino acids could have contributed to the post-exercise recovery and tissue repair, therefore becoming a factor in the PP and MP training-induced increases. When creatine ingestion is isolated during short-term supplementation, the results of several studies appear to show encouraging results. Tarnopolsky and colleagues showed that short-term, high-dose creatine supplementation (20g a day for 4 days) markedly improved high intensity exercise performance, specifically in anaerobic cycling power and dorsi-flexor maximal voluntary contraction torque. They also found that males and females responded to the supplementation in a similar manner, with no gender effects apparent {{49 Tarnopolsky,M.A. 2000; }}. Volek et al found comparable results when they looked at maximal effort muscle contractions in individuals during repetitive sets of bench press and jump squats, after receiving 25g doses of creatine every day for a week {{50 Volek,J.S. 1997; }}. CM vs. PEG A subsequent study by Beck with Herda et al {{2 Herda,T.J. 2009; }} compared the effects of CM with that of differing doses of polyethylene glycosylated creatine (PEG), another form of CEE. Using the standard recommended safe dose of 5g a day of CM, the results after training were compared to those obtained taking 1.25g and 2.5g of PEG. Similar tests to the ones previously mentioned in other studies were used to measure muscle strength, endurance and power output in a group of young, healthy men. The difference with this study was that there was no extra training (aerobic or resistance) undertaken by any of the subjects from the level of exercise that they performed regularly before entering into this study. Instead it was just the simple administration of their respective supplement or placebo for a period of 30 days. CM had the effect of increasing body mass and muscle strength in the 1RM tests using the bench press and leg press. Those individuals taking the PEG doses found simila r improvements in muscle strength but no change in their body mass. Neither group had improved PP performance or muscle endurance when compared to the placebo group, respectively measured using the countermovement vertical jump and WAnT, and repetitions to failure at 80% of 1RM using bench press and leg press. It had been suggested by Fry et al that PEG could help facilitate creatines movement across the sarcolemma during gastrointestinal (GI) absorption, therefore a smaller dose of this form of creatine would be needed to obtain potentially the same results as CM (Fry, CF. 2007). This study showed that while a smaller dose of PEG did show comparable results to those obtained using CM, further studies are required to determine its effects when combined with resistance training. One notable practical application is that both CM and PEG groups experienced improved 1RM performance without undertaking a loading period. Many manufacturers of CM encourage a week of loading of the creatine supplement i.e. a larger dose of 20-25g followed by a maintenance period taking a normal 5g dose. Going on from this, with further research required, it might be possible to achieve the same improved performance in 1RM exercises usually seen after 5g.d-1 of CM, by taking a smaller daily dose of PEG. Again, it i s possible results may vary when combined with a set period of resistance training and further research is required in this area. CM vs. CEE, with special reference to the creatine transporter A 2009 study by Spillane et al concentrated on looking into the effects of CEE supplementation on muscle performance after a seven week period of heavy resistance training {{26 Spillane,M. 2009; }}. As mentioned briefly earlier, CEEs proposed advantage over CM is that it is more bio-available due to the esterification process it undergoes, thereby making it less hydrophilic. The manufacturers of this particular variety of creatine also claim that due to enhanced sarcolemma permeability in favour of CEE, it is able to taken up into muscle without the need for the creatine transporter (CT) {{26 Spillane,M. 2009; }}. The CT mediates the uptake of creatine in skeletal muscle against a concentration gradient and is helped by a Na+-dependent transporter {{94 Guimbal,C. 1993; }}. A review by Snow and Murphy looked at the literature concerning the CT, primarily how it is regulated and what gene expression is responsible for its activity {{51 Snow,R.J. 2001; }}. They found that the CreaT1 gen e was expressed in a variety of tissues, including neural, cardiac and skeletal muscle, and that the activity of the transporter protein itself was regulated by substrate concentration, cellular location and a host of other factors. A subsequent review in 2003 by the same authors demonstrated that the creatine content in muscle was predominantly determined by extracellular supply and the expression and activity of the CTs {{52 Snow,R.J. 2003; }}. They also found that after creatine supplementation, the increases seen in total muscle creatine levels were variable and hypothesized that potential factors responsible for these differences could be carbohydrate intake, average level of exercise and possibly fibre type. Supplement companies make specific reference to CEEs supposed benefits over CM, indicating that it is easier to absorb than other versions and offers faster results (MyProtein.co.uk web site, accessed 27-1-2010). However, these claims have been disputed, not only by the International Society of Sports Nutrition, as mentioned earlier, but also by another independent study that showed that CEE was unstable at low pH conditions and as a result, would be taken up less by muscle than an equivalent dose of CM (Mold et al 1955). The results of the comparative study by Spillane et al seemed to concur with these objections. Performance and muscle strength were improved to a similar level of those using CM and those in the placebo group, while body composition was unchanged. They concluded that the improvements seen in the study were most likely due to the training regime, rather than the supplementation and that CEE ingestion markedly increased the serum creatinine levels without any notable change in serum and total muscle creatine levels. This can only lead to the observation that the CEE was being degraded while in GI transit and its uptake by skeletal muscle was insufficient enough to prevent further degradation to creatinine or increase the levels of creatine within the muscles {{26 Spillane,M. 2009; }}. This is a very interesting revelation considering the manufacturers claims of increased absorption and it shouldnt go unnoticed that all supplementation mentioned in the study (placebo, CM and CEE) provided no additional benefit to the training specification undertaken by the volunteers. A loading phase (approx. 20g/day) of five days was followed by a maintenance period lasting 6 weeks (approx. 5g/day) and the training programme was a fairly intense one with participants required to train four times a week. Perhaps the more demanding training schedule was sufficient in providing maximal muscle strength increases and supplementation could not possibly have had any b eneficial effect. This is open to discussion however, as so far every study that has been reviewed in researching for this paper has shown that creatine increased the effects of training. Effect on repetitive sub-/supra-maximal exercise Improved performance in repetitive exercises such as repeated sprints (6x60m) are more relevant than one-off maximal performances when it comes to assessing creatines effect in a sporting environment. The ability to perform longer and harder during interval training sessions gives way to better results and hopefully better performance in competitions. It is essential to differentiate this form of exercise from endurance training, which involves long concerted efforts with little, if any, rest time. It could be said that improving this aspect of your training will give rise to improved performance in 1RM tests so the effect of creatine supplementation needs to be evaluated in both aspects. High intensity interval training (HIIT) is a specific type of interval training and is utilised by some of the studies subsequently mentioned. It requires maximal effort for a short duration of time, interspersed with active recovery at a lower intensity to the main workout. The thinking behind this form of training is that intramuscular levels of H+ will be elevated when the next set of exercise begins and this should force the body into improving intramuscular buffering capacity {{54 Costill,D.L. 1984; }}. This should then improve performance in future training/events by delaying fatigue. A 2003 study by van Loon et al looked at the effects of CM supplementation, without training, on performance during repeated supra-maximal sprints on a cycle ergometer as well as an endurance cycling exercise {{24 van Loon,L.J. 2003; }}. Whole-body and muscle oxidative capacity and substrate utilisation as well as body mass were also measured before and after to monitor any potential changes. The main aim of the researchers was to determine any differences in the results of the aforementioned values, between creatine loading and prolonged use of the supplement. Performance in the repeated sprints was improved in both groups, while there was no improvement at all in the endurance exercise. Muscle oxidative capacity was also unaffected. The researchers had based their predictions, on a possible change in the oxidative capacity, on findings by Brannon et al that showed increased muscle citrate synthase activity in rats after prolonged creatine supplementation {{53 Brannon,T.A. 1997; }}. Their results suggested improvements in the values mentioned because citrate synthase is a mitochondrial marker enzyme, although almost every study that has looked into creatines effect on endurance has found no (or even negative) effect. Unfortunately this study also came to the same conclusion. Kendall et al carried out a similar, subsequent study in 2009, looking into the effects of combining HIIT with creatine supplementation and assessing any changes in critical power or anaerobic working capacity {{3 Kendall,K.L. 2009; }}. Critical power reflects the individuals ability to sustain their highest power output for an extended period time while anaerobic working capacity is their total metabolic work capacity, independent of oxygen use {{3 Kendall,K.L. 2009; }}. Creatine significantly improved critical power compared to the placebo and control groups while anaerobic working capacity was unchanged in all test subjects after treatment. This suggests that HIITs effects on endurance performance changes may be enhanced by creatine supplementation. A possible explanation for this is that PC is a major component of biological buffering and, as has been shown already, creatine supplementation can increase the bodies total creatine stores therefore allowing for improved pre-exercise PC availability. Although the participants of this particular study did not have their intramuscular levels of PC measured, other studies have repeatedly shown a significant increase after varying levels of supplementation (3-20g/day) {{11 Harris,R.C. 1992;1 Vandenberghe,K. 1997; 55 Casey,A. 1996; }}. Therefore, not only does creatine supplementation help to replenish PC stores and increase energy production in the ATP-PC energy system, but it also serves to delay the onset of muscle fatigue by prolonging the build up of ADP and inorganic phosphate (Pi), known factors in the activation of anaerobic glycolysis (Cramer 2007). The studies covered in this paper have mostly used young, healthy males to test the effects of creatine supplementation so to ensure fair coverage of the population the next study to be considered examines the effect of the ergogenic aid in sedentary older women. Gotshalk et al (2008) showed significant increases in upper- and lower-body maximal strength in thirty 58-71 year old women after CM supplementation The effect of creatine supplementation on muscle development The aim of this section is to attempt and explain the structural changes that take place after creatine supplementation that facilitate the improvement in muscle performance shown in the aforementioned studies. It has already been shown by numerous studies that exogenous creatine can replenish the PC stores and lead to faster regeneration of ATP and therefore allow a longer and more intense exertion. This next section will focus on how creatine potentially alters the morphology of skeletal muscle and how it can amplify the effects of training. Muscle fibre type and size A study by Volek et al examined the cross-sectional area and proportion of muscle fibre types before and after supplementation and twelve weeks of heavy resistance training {{56 Volek,J.S. 1999; }}. Those subjects in the creatine group had significant increases in the cross-sectional area of all four types (Type I, IIA, IIAB IIB) while increases in the placebo group were much smaller, with only Type IIA fibres reaching a significant value of change. Interestingly it was this type of fibre that increased in proportion in both groups after training, but more so in the creatine subjects (9% vs. 7%). They also found a significant decrease in Type IIB fibres in both groups (9% and 6%) indicating that the training was responsible for a slight shift from the fast glycolytic type towards the fast oxidative type of fibres, with creatine accentuating this change. This change is to be expected as resistance training has previously been shown to decrease the percentage of Type IIB fibres and en courage the transformation from Type IIA > Type IIAB > Type IIB in as little as five workouts {{18 Balsom,P.D. 1994; }}. As the authors state in their discussion section, the greater gains in muscle fibre hypertrophy seen by the creatine group implies enhanced myofibrillar synthesis and/or reduced breakdown. Myosin heavy chain synthesis Ingwall and colleagues had shown in 1972 that skeletal muscle, formed both in vitro and in vivo, would synthesise myosin heavy chain faster when supplied with creatine in vitro {{57 Ingwall,J.S. 1972; }}. Ingwall had been one of the first to postulate that the hypertrophy of skeletal muscle as a result of increased muscular activity might be due to an end product of the activity promoting contractile protein synthesis {{57 Ingwall,J.S. 1972; }}. The results of his early experiment were consistent with the idea that creatine acts as a positive-feedback effector within the system relating muscular activity and muscle protein synthesis. However it is still unclear whether the same mechanism is applicable in vivo as creatines beneficial effects appear to act indirectly through the enhancement of the intensity of trai

Causes of Job Turnovers and Staff Retention Issues

Causes of Job Turnovers and Staff Retention Issues STAFF RETENTION INTRODUCTION Staff turnover has become the norm today in the manufacturing, service and merchandising / merchandise industry. Employees are moving from one form of employment to another because of several factors that the employers have not yet grasped. In this regard many industry players are busy defining ways to protect turnover of its employees. The most affected part of this is the merchandising industry. In the bid to prove muscle in the fastest growing industry executives in the merchandising industry are fighting hard the high trend of their staff consistently changing jobs (Omondi 2). Today generating an atmosphere favorable and valued by all employees in the ever changing employee market may not be as pain-streaking as it may appear to the larger population. It engages a number of issues may make the brilliant minds that make up your staffs want to stay in the organization. A combination of this contribution may eventually lead to higher number of employees and thus reduce turnover. The contributions made above require that they be performed in tandem for observable achievement to be achieved. Grasping the skill of staff retention requires that management delve deeply into what causes turnover of staff in institutions. Many questions should be put on the table in order to ascertain reasons why one would want to work in one organization and not prefer to work in another organization. The managements should not rest at that but proceed to look into the subsequent period that the employee has been absorbed into an organization. By asking these questions it is easy to discern that there are a lot of issues that have been left wanting for a long time. i find it easy to look at this issues by sympathizing with the employee and trying to assume his shoes at the company. This in real meaning requires doing proper research on standard ethical models that might be brought on board to encourage retention of employees. In the recent past the employers used to retain employees . The confidence thus gained goes down well with those in the precincts of work thus offering them purpose and presence. Boosting the moral of workers is one way of improving confidence of staff. In this regard even the general productivity of the company of the company can be noticed. Working closely and collectively in addition grants the staff presence. Al in all its just a matter of saying thank you as morality demands. There are different styles of leadership in institutions that influence how relationships in the work place take place. People in leadership roles should be in the fore front in show wing proper codes of conduct to their employees, as opposed totaking the hind seat. In turn the employees may feel very motivated within the working environments that they are working. This enabling environment will thus lead to a sense of belonging by the individuals and cohesiveness thus leading to teamwork translating into a proud team. For one to retain staff he or she has to consider several important issues of the work place. BACKGROUND Draper Co. Ltd. Found in 1987 is a sweater manufacturer that employs more than 100 people in Hong Kong. Since garment companies had bloomed in recent years. The role for merchandising people become more difficult and the manpower is short in the labor market. Draper is facing the problem of high staff turnover rate. In addition, with opening of the mainland market. Many foreign enterprises had set up their merchandising sections in Hong Kong and some enterprises also invite Hong Kong garment companies to cope with their expanding business. As a result, the job vacancies of merchandisers increased tremendously. Among the merchandising industry, garment sections are highest in demand for merchandisers. This is due to the fast growing of the sectors as well as the high employee turnover rate and the lack of talent in the labour market. With the goal of identifying predictors of turnover, factors and employees intention to leave or stay with the company will be the major issue of Draper Co. Ltd. 1.2 RESEARCH PROBLEMS Initially, the establishment of the project required the involvement of different parties who would provide data and statistical analysis. The study required involvement of external organizations which would require them to allow access their staff to cooperate during the course of the research. Unfortunately some of these merchants turned down request to take part a little after the project was already initialized, it was quite unfortunate. The team of researchers contacted several nationwide merchandise groups to request them to take part in the research as a subsequent measure. Within a short period of time, two particular merchandisers articulated formal concern and primarily arranged to play a part in the project but with the approval of the Board of Governors of their respectful organisations. The team of researchers used up considerable hours meeting with a variety of the team of people representing the merchandisers and giving important information related to the research and showing presentations that highlight the scope of the study. An agreement was made with these merchandisers that the research panel would conduct industry job and staff retention survey within the merchandise organization, rather than concentrating on organizational loop holes as it would imply that there are indeed loop holes, in their respective organisations which might not be the truly case. However because of various unpredicted situations including the falling ill of one of the team members who acted as coordinator of the research team and these respectful merchandisers, the merchandisers in the end made the decision to withdraw its cooperation, leaving operation of the research between a rock a rock and a hard place. The research team then informed the Draper Co. Ltd of the current problems and suggesting a different research method design that would still be in line aims of the project and the objectives outlined before the research was initially flagged off. In this respec t, a decision was made to advertise across various merchandise outlets to secure individual people working as merchandisers to act as respondents from different retail outlets, thus eliminating the process of approaching company heads or Board of Governors for endorsement to guarantee a speedy and effortless contact with respondents. The Draper Co. Ltd was highly involved in endorsing the submission for change in the approach for the research. The research carried out by the team concerned conducting 100 partially controlled telephone interviews with with merchandisers from different merchandising firms including own staff at Draper Co. Ltd . The research method design of the survey was cautiously designed and conversant with preceding works that dwelled on employee equality and diversity concerns all over the work evironment (e.g. Sutherland and Davidson, 1997). The design of the interviews was such that it could be in accordance with the aims and corresponding objectives of the Dr aper Co. Ltd and eventually deal with a array of concerns as well as the recognition of possible occupational improvement barriers and the recognition of approaches for conquering these limitations, chances for education and training, job promotions and provision for leadership. The partially controlled interview timetable was then stored in secure modules and safe websites secured with passwords, which eventually made it easy for members of the research panel to enter information directly into the research database and online pages, and at the same time carrying out interviews with respondents all over the merchandising industry. The details of the research methodology and what will be contained in the schedule for the is described in the subsequent sections. RESEARCH OBJECTIVE This study was led by a research team commissioned by the Draper Co. Ltd. The research team was selected by the management of the company with advise by the legal advise wing experts. It was agreed that 16 members be brought aboard the the team of researchers. The main goal of identifying predictors of turnover, factors and employees intention to leave or stay with the company will be the major issue of Draper Co. Ltd. The aims of the project were as follows: To examine two sets of potential causes of job turnovers and eventual staff retention mechanisms: firstly, those that impede the retention of workers in the organization and secondly, those that speeds the exit of the players from the organizations. Identify strategies for overcoming these barriers Investigate the feasibility of constructing a national database, documenting the career paths of women in the merchandise industry Develop, publish and disseminate good practice guidelines and recommendations using reports, conference presentations, feedback seminars, academic journals and merchandise specialist and national press. The objectives of the project were to: Investigate two sets of potential reasons for staff leaving the company: firstly, those that accelerate the exit of workers and merchandisers and secondly, those that impede the efforts of retaining staff in the organization. Identify strategies for overcoming these reasons. Investigate the feasibility of constructing a national database, documenting the career paths of workers in the merchandise industry. Develop, publish and disseminate good practice guidelines and recommendations using reports, conference presentations, feedback seminars, academic journals and merchandise specialist and national press. RESEARCH QUESTIONS Why this company has high staff turnover rate Why staff relationship will make new comer difficult to fit in team work What relationship caused high staff turnover rate How to retain staff in this company Does the management policy affect staff retention Does the company is responsive to employees needs and wants Does companys reputation retain staff RESEARCH METHOD 3. Research Methodology Having discussed the complexity of the retail industry and the related literature, the following chapter attempts to identify and describe the research design and sampling type. After which, the chosen research method will be introduce and how the collected data is being tabulated will be discuss. In addition, the hypotheses of this study will be derived at the later part of this chapter. 3.1 Research Design Research design specifies the methods and procedures for conducting a specific research project. It is a detailed blueprint used to guide the implementation of a research study towards the realization of its objectives (Wong, 1999). According to many authors (Churchill, 1999; Wong, 1999; and Zikmund, 2000), there are three types of research design, namely the exploratory research, descriptive research and causal research. Exploratory research is known to be the best suited for situations that have relatively little or nothing known about the study. The essence of this research design is to focus on two main ingredients listening and discovering, in order to provide a great understanding of a concept (Wong, 1999) and to clarify and define the nature of a problem (Zikmund, 2000). These authors also pointed out that exploratory research can be conducted with four approaches which are literature search, experience survey, focus group discussion and in-depth interview. These open-ended, flexible and interactive qualitative approaches help to formulate problems more precisely but not providing accurate statistical information. Descriptive research aims a describing the characteristics of the population under the study such as the behaviours of consumers. It is primarily concerned with the gathering of numeric, measurable data and it is recommended when the research purpose is centered on providing accurate, statistically reliable data. Descriptive research is being broken down into both longitudinal and cross-sectional studies (Zikmund, 2000 and Wong, 1999). Longitudinal studies involve panels (Churchill, 1991) and provide measurements at successive points of time of an event. On the other hand, being the most common and familiar (Churchill, 1991), cross-sectional studies describe an event at one particular point of time and it is useful in facilitating comparisons between different population subgroups (Wong, 1999). Finally, causal research is to explore and establish a cause-and-effect relationship, if any, between variables through laboratory and/or field experiments (Wong, 1999, p58). Cross-sectional study was chosen for this study. This is because cross-sectional study relies on a sample of elements from the population of interest that are measured at a single point in time (Churchill, 1999) and it can at best yield measurement data (Wong, 1999, p. 57). Hence, this research design suit in this study because it attempted to measure how consumers make decision. 3.2 Sampling Design Wong (1999, p.54) pointed out that descriptive research requires a reasonably large number of respondents (i.e., sample size) to supply the required information. Although it is recognized that a convenience sample is not always truly representative of the population, the author of this study had decided to adopt this method due to time restraints. The author adopted convenience sampling of non-probability sampling as it aids convenience and efficiency and also generates a large number of sample sizes. This is because it involves the selection of people who are most conveniently available to the interviewer (Wong, 1999). Due to time constraint, the gathering of responses for this study would be greatly base on convenience. Convenience gathering of responses and ability to contact the respondents (if necessary), has allowed the author of this study to choose both Marketing Institute of Singapores (MIS) part-time and full-time students as the main target respondents. In addition, friends, colleagues and family members of both the respondents and the author would be approached as well. 3.3 Data Collection for this Study According to Wong (1999), marketing data may be classified into two basic types: primary data and secondary data. Primary data refer to those collected to meet the specific research needs at hand. Secondary data on the other hand, refer to existing information which has previously been collected and reported by some individual or organization, and which are other than the research problem at hand. Thus the distinction between primary and secondary data lies in the original purpose of data collection. 3.3.1 Secondary Research Secondary data is an essential element of almost all research carried out. According to Churchill (1999, p. 253) secondary data possess significant cost and time advantages. This is because, the existence of secondary data can in many instances dismiss the need for potentially expensive and time-consuming field work as secondary data exists aplenty from internal and external data sources (Wong, 1999). Apart from time-saving and cost economics, secondary data is less subject to intentional bias. Also as certain types of information may be impractically or virtually impossible to gather through data approach, secondary data are the only alternative (Wong, 1999). Therefore, secondary data enable this study to avoid biasness that might be made unintentionally by the author during the development of the hypotheses. Hence in this study, journals from electronic databases such as Emerald and Ebsco were reviewed to aid the development of the study. The use of journals was to serve as a basis to draw the hypotheses of this study. However, Wong (1999) pointed out that one of the disadvantages of secondary data is that it became outdated easily in an ever-changing environment, and often, there were differences in classification or measurement as well as lack of accuracy. The above appeared true to the author as some of the journals being reviewed appeared to be outdated and inaccurate due to different areas of focus. The author also found that there was limited access to many online research websites and the availability of journals on store atmosphere in the retail context was also limited. Therefore both the retail and service context were being reviewed in the process. With the difficulties mentioned above, it was anticipated that the secondary research found would not be sufficient to fulfill the objectives of this study. As mentioned by Churchill (1999), when problem is not yet resolved with secondary data, the researcher should proceed to primary data. Therefore, the author of the study moved on to gather primary data for the completion of this study. 3.3.2 Primary Research Primary data prove its importance when the required information for marketing research/evaluation may not be available from secondary data sources. For the purpose of this study, the author had decided to use quantitative research. This is because, according to Wong (1999, p.110), quantitative research is used when the primary objective is to derive numeric or quantifiable data which is statistically accurate and reliable. Quantitative research is also recommended when there exists a need for accurate numeric data. Due to time constraint, the author decided to avoid open-ended questions and adopt close-ended questions on the questionnaire. This is because, close-ended questions are easily administered by an unskilled interviewer compared to open-ended questions and it is also much easier and faster for statistical data tabulation and data comparison. In addition, the checklist of responses in the questionnaire helps reduce difficulty in memory-recall that respondent might encounter in responding open-ended question (Wong, 1999). On the other hand, the checklist of responses may not be as comprehensive and alternate responses that appear in the checklist may create position bias, which will cause the respondent to be unable to freely express him or herself, and often detailed information is being missed (Wong, 1999, p.138). 3.3.3 Questionnaire Development The questionnaire used for this study consists of three sections, namely demographics, Closed-ended questions (Dichotomous questions Multiple-choice questions) and Scaling questions (Agree-disagree questions). Section A served to gather data on respondents personal particular such as gender, age group, highest education level attained, occupation and monthly Income level. Section B aimed to gather data on respondents view towards the impact of store atmosphere on consumers emotions, purchase and repatronage behaviour. It will determine to what extent each atmospheric elements influence respondents mood and purchasing behaviour. Five-point Likert-scale statement (1=Strongly Disagree and 5=Strongly Agree) was being used to allow respondents to rank and identify the degree of influence of each of the atmospheric elements. Responses were also sought regarding consumers patronage behaviour. 3.3.4 Pre-testing The objective of pre-testing is to ensure that the questionnaire used in this study is easily understood and not misinterpreted by the respondents. There should also be minimal possible difficulties faced by respondents in answering the questionnaire. For the reliability of this study, pre-testing is vital to ensure the accuracy of the data collected. The questionnaire was pre-tested via a small-scale pilot test with 5 respondents and subsequent changes were made. The author sent the questionnaire via email to the 5 respondents and they where asked to attempt the questionnaire and provide comments and feedbacks. After gathering the feedbacks and comments, the questionnaire was being modified and refined to meet the objectives of this study. In order to improve the clarity of the questionnaire, redevelopment of the questionnaire was required. The author had to refine the section A and rephrase some misleading questions in Section B. Some questions that were being duplicated and confusing to the respondents were omitted. New questions were also developed and integrated into the questionnaire to achieve the objective of the study. 3.3.5 Final Data Collection After redeveloping the questionnaire, the new questionnaire (appendix ) was ready for the actual distribution and data collection. The questionnaire was being distributed both online and offline to MIS part-time and full-time students as well as their friends, colleagues and family members. Naturally, offline respondents are more responsive to the completion of the questionnaire. This is because they tend to complete the questionnaire the moment they receive it and return to the author right after completion. Although online distributions of the questionnaire enable wider participation and easier distribution, it is commonly view as spam mails and ignored by receivers. Therefore, there were a total of 49 responses from offline distribution and 39 online responses which resulted in a total of 85 responses that served as primary data for this study. 3.3.6 Data Analysis Method SPSS 13.0 version was being used for data analysis in this study. The author made use of one sample T-test, paired sample T-test, chi-square and correlation to conduct testing of the hypotheses. The statements used to measure the variables were assessed on a five-point Likert scale, ranging from strongly disagree to strongly agree with numerical value of one being strongly disagree and five being strongly agree. 3.4 Hypotheses â€Å"A hypothesis is a statement that specifies how two or more measurable variables are related. A good hypothesis carries clear implications for testing stated relationships†, (Churchill, 1999, p.101). As stated, for this study, it was important to measure the impact of the influence of the atmospheric elements of a store on consumers mood and behaviour. Hence, the following hypotheses were derived for this study. Based upon the theories reviewed, it is hypothesized that: Mood H1a: Colours has a significant influence on consumers mood in the store H1b: Lighting have a significant effect on consumers mood of the store H1c: Music has a significant effect on consumers mood of the store H1d: Scent has a significant influence on consumers mood of the store H2: Mood is positively influencing consumers length of stay in a store Spontaneous Purchase H3a: Consumers will have a more favourable attitude toward merchandise with the effects of store atmospheres H3b: Effects of store atmospherics on merchandise is positively influencing spontaneous purchase in the store H4: Income level is influencing spontaneous purchase that is caused by store atmospherics Repatronage Intention H5: Consumers will exhibit greater degree of patronage intention when the store atmosphere appeals to them H6: Gender, Age and Education level influence consumers evaluation of stores image The responses gathered from the questionnaire were then entered into SPSS 13.0 for statistical analysis. 3.5 Summary of Chapter 3 Secondary data such as journals and textbooks were being reviewed before conducting the actual primary research. This was to allow the author to further understand the review on Store Atmospherics, mood and repatronage behaviour before developing the questionnaire for primary data collection and to develop the hypotheses of this study. A total of 89 responses were collected via online and offline distribution to enter into SPSS 13.0 for statistical analysis. Conclusive Research Design Descriptive Research Method: Data Analysis is quantitative Secondary data survey Questionnaire Survey Data Collection Survey analysis by launched an Employee Workplace Survey to gather data that would identity why do employees stay/leave the company? Identifying factors influencing retention to gather data from across the employee population of the company. TERMINOLOGIES DISSERTATION OUTLINES Chapter 2 Literature Review 2.1 Introduction This Section looks at the main literature in this area. The first sections focus on the structure of merchandising and the broader profile of the sector. The section then moves on to its main concern which is the job retention of merchandisers at junior and senior levels in merchandise. Merchandising is an economic sector, which has traditionally been associated with the employment of merchandisers. Overall, 60% of low skilled employees are merchandisers and 40% are skilled. Whilst these figures show that the merchandise sector clearly employs a larger number of low skilled than the skilled, it is not a ‘balanced industry (Skillsmart, 2006). The representation of low skill workers in the merchandise sector however, follows a number of important patterns. Official statistics are used to highlight the predominance of merchandisers in part time work in the merchandise sector and the under representation of merchandisers at senior levels. According to Skillsmart, (2006), official f igures are general and are unlikely to provide a clear understanding of the dynamics relating to the position in which merchandisers are employed in merchandise sector. The following sections therefore outline theories that have been offered to account for these gender disparities, particularly in relation to barriers for merchandisers attempting to progress into senior management positions. An examination of managing diversity is then offered and potential mechanisms for ensuring merchandise organisations fully utilise the talents of all employees to maximise productivity is discussed. 2.2 The structure of the merchandise sector The merchandise sector is the largest private sector employer in the Hong Kong yet it is rarely recognized as such. Skill smart (a not for profit organisation, set up and part funded by Government to identify and address the skills needs of the Hong Kong merchandise sector), suggest that this is, possibly because its workforce is not concentrated in any particular region or locality. In fact, the merchandise sector is the largest public sector employer in the Hong Kong. Furthermore, Wang XI Inc is the Hong Kongs second largest employer after the Jubilee (Skillsmart, 2004). Overall, the merchandise sector employs three million people throughout the Hong Kong, which accounts for approximately ten per cent of employment throughout the Hong Kong. However, the structure of the industry is unusual, and is described by Skillsmart, as ‘hourglass shaped. The overwhelming majority (95%) work in firms with less than ten employees. Consequently, there is significantly less (just over two hundred) merchandise employers with more than fifty staff, reflecting the â€Å"hourglass shape† of the industry profile. 2.3 Present profile of turnover of employees Employment expectations have risen slightly in (Q1) from an already high level in Q4. Of the 514 executives surveyed, 54% expect to increase their hiring which is slightly up from 53% the previous.Year-on-year, expectations have remained steady. The 54% planning to grow headcount this year is at the same level as Q1 2006, though there are some variations between the sectors surveyed. Companies are extremely confident about how they will perform in the next six months with 95% of respondents forecasting their companys performance to be excellent or good in the first half of 2007. Respondents in Hong Kong report higher levels of staff turnover than in any other market surveyed in Asia with 37% stating that turnover in the last twelve months has exceeded 10% (Hudson, 2007). Hudson, one of the worlds leading professional recruitment, outsourcing and talent management solution providers, today released findings of its comprehensive quarterly Hudson Report for Asia. With a reputation as a key socio-economic indicator in the current marketplace since its Asia launch in December 1998, the survey has been built on the premise that employers expectations of an increase or decrease in staffing levels represent a significant indication of their optimism in the growth of their organisation and their industry as a whole. The Hudson Report represents the expectations of over 2,200 key employment decision makers from multinational organisations of all sizes in all major industry sectors, with 514 of these executives based in Hong Kong. 2.4 The general profile of employees in the merchandise sector Traditionally the merchandise sector is associated with the employment of low level and unskilled workers, the vast majority of whom work in the lower ranks of the organizational hierarchy. The profile of employees in merchandise also follows a number of other patterns. The merchandise sector for example employs a large proportion of young people. According to recent estimates 29% of those employed in the sector are between the ages of 16 to 24. This is compared to the overall economy figure of 14%. It has been suggested that this figure may be due to the popularity of merchandise as a part-time occupation for young people and students (Skillsmart, 2006). Merchandise is also a popular choice for older workers (those over 55). In terms of ethnic minority employment, the merchandise sector employs a similar proportion to those figures available nationally (Skillsmart, 2006). Recent research has shown however, that certain recruitment practices may prevent ethnic minorities from gaining employment in merchandise organizations. For example a study for Birmingham and Manchester cities in Britain for example, found that employers might specify jobs as a matter of course that require the staff to work on Saturdays without realizing that a large pool of potential workers would be unable to work on this day as it is their Sabbath (Vector research, 2003). 2.4 The trends common in the merchandise sector Merchandise is an economic sector, which has traditionally been associated with the employment of diverse people of different background. Overall, 55% of merchandise employees are women and 45% are men (Skillsmart, 2006). This gender factor in the merchandise sector remains fairly consistent throughout the nations and regions of the Hong Kong and this profile has been fairly consistent over the last 10 years. Skill level has also played a bigger part in influencing how long an employee is wiling to stay in a given organization. Better salaries in other organizations may lead to employees moving from their respective place of work in pursuit for better opportunities(Hudson, 2006). Level of qualification gives workers a broader spectrum of work opportunities that they gladly take into considerations. Skillsmart (2006) suggest that Hong Kongs larger ethnic population is likely to be the source of this greater proportion of the workers in the capital run by ethnic minorities may proprietorship driven by highly skilled male people. It is important to note however, that t he representation of retention in the merchandise sector follows a number of

The Water Droplets Journey :: Water Cycle Essays

Day 1 Once upon a time high above the earth, fluffy white clouds drifted through the atmosphere. In the clouds lived a family Droplet of water, round and content with life. For as long as I could remember, I spent my days lying on my back, relaxing and soaking up the sun's warm rays. One day, I took my usual place in the sun but the light didn't seem to be as bright. In fact, as the day went on, it grew darker and darker, loud claps of thunder shook the cloud, and the Droplet felt as if he were getting so heavy he could hardly move. This is called precipitation. Suddenly, I felt myself falling from the cloud. Down, down, down he fell, farther and father from home. At last I landed on the earth, in the dark green foliage of the rainforest. Around me as far as I could see were tall trees, dense green leaves, red mushrooms and multicolored insects of every shape and size. Strange creatures surrounded him, and the sounds and sights were like nothing I had ever seen or heard before. All I was sure of was that I wanted to go back home. But how? Day 2 It is now day 2 3:00 am and I am going to be out of the ocean at 12:00 pm. I have changed from an infant into a primary. I am having so much fun sailing across the ocean. It is now 12: am and I am 12hrs away from being on land. It is now 3:00 pm and I am tired of sailing but I have to keep pushing. I am having so much fun. It is now 5:00 pm and I?m rushing hoping I will get finish early I can see the land and I?m almost there. All I have to do is reach the land. I?m there finally all sweaty and wet. Day 3 I?m on the step to soaking in the ground and I?m draining in the ground. I?m waiting to get cleaned all of a sudden a worm comes and eat me. I guest the worm didn?t see me there so I bang on his yelling ?Hey you umm wormy can I get out of here pl-ease?

Brave New World - Society And Socio-economic Class :: essays research papers

Discuss how the society in Brave New World works to ensure that people do not change their socio-economic class. Through Brave New World, Huxley depicts a new, industrialized world, which is financially stable and has prevented poverty and self-destruction. Dictatorial governments are there to ensure stability and maintain perfection of the world. Therefore, just like under any other totalitarian government, social, mental and economic freedoms are abolished in order to retain social stability. The government eliminated these freedoms by censoring art and religion, by predestining peoples’ social caste prior their birth, and by controlling each individual’s life with the introduction of conditioning. At the beginning of the novel, the Director addresses his students and mentions, â€Å" We also predestine and condition. We decant our babies as socialized human beings, as Alphas or Epsilons, as future sewage workers or future Directors of Hatcheries,† (p. 29). Citizens of the World State are categorized into distinct social classes, before they come into existence. Mr. Foster explains, â€Å"The lower the caste, the shorter the oxygen,† and this shows how chemical conditioning of the embryos presets the mentality and physical features of individuals towards a certain standard specified by the government. (p. 29) In an autocratic society whose aim is to maintain perfection, people no longer have the right to choose who or what they want to be. The government engineers babies to grow into efficient adults, who will then again contribute towards a stabilized society. After birth babies’ minds are altered to accept the moral education of the government. Two processes the new world uses to control human judgement are the Neo-Pavlovian process and hypnopaedia. The children, during early childhood, are trained to like and dislike certain aspects of life, nature, and science so that they can consume the maximum resources. Beta babies receive electric shocks in the presence of flowers and books and then the Director teaches how, â€Å" They’ll grow up with what the psychologists †¦ call an ‘instinctive’ hatred of books and flowers †¦ they’ll be safe from books and botany all their lives," (p. 36). The conditioning of the children forms a barrier in their minds, so that they are never free to decide for themselves, but are always bounded by the instructions of the state. Thus, the government is achieving its goal, the maintenance of stability. The Alpha students also got a chance to hear one of the hypnopaedic repetitions addressing Beta babies which echoed, â€Å" Alpha children wear grey.

Drug Companies and Ethics Essay

After researching pharmaceutical companies, I quickly realized this is a very controversial topic. I’m not certain anyone in many of these companies have very many moral standards. Drug companies seemed to be very profitable from the researchers to the drug reps that deliver â€Å"gifts† and sample meds to the doctor’s offices that push their medications. Many activists will argue that drug companies put themselves before human rights. Companies violate health related human rights by prioritizing profits over peoples access to essential medications. Many large scale drug companies argue that they are proudly taking the stakeholder approach and striving to promote fair labor practices and non-discrimination in the workplace. They will also argue that the reason medication prices are so high is because of all of the research that is involved in developing a medication, while activists argue that meds are so expenisve due to the marketing they put into a drug in the first several years. I found researching the pharmaceutical companies to be very interesting. It was very hard to get past the negative controversies and debates to find anything positive about any one company. However, I finally found one company in particular, Merck & Co. that has taken responsibility and turned around some negative press by developing a program that helps thousands of people. Lynch 2 Merck is one of the largest and most profitable drug companies in the world, but they have also been a leader in a donation program that helps Third World countries in Africa, South America and Yemen since the 1980’s. Merck became one of the first drug companies to become socially responsible by donating to countries that could not afford the essential medications needed to prevent a disease that caused something as severe as blindness in hundreds of people. Their medication, Mectizan, taken annually can alleviate and has ultimately eliminated this disease in some countries. Since the 80’s when Merck started this program many other drug companies have jumped on board. Companies such as Pfizer, Johnson & Johnson and GlaxoSmithKline have all started taking social responsibility and are now donating through programs to these Third World countries. These companies are donating medications that our country takes for granted and that we may not need in our everyday life. Johnson & Johnson donates a medication that rids their children of intestinal parasites while Pfizer donates Zithromax to eliminate trachoma. If it were not for these companies donating such large quantities of these drugs every year, millions of lives would be lost. I find it very interesting that the drug companies that many people complain about and that make millions a year in profits seem to also be able to do such wonderful things in these countries. I found many articles that complained about the CEO’s and about the terrible morals that some of these pharmaceutical companies are known for. I think that when it comes to morals and ethics people see what they want to see. Drug companies have had a bad name for many years so you don’t see a lot of positive press and articles such as the one I found. It was actually refreshing to read about the d rug companies that donate and the lives they save. Some of us may not agree with how these companies push their drugs into our doctor offices and we may even say that they do not practice great ethics, but it seems as if these companies are at least trying to keep a â€Å"good name.† I am certain that the people in these Third World countries are very grateful to the drug companies that donate because not only are these companies saving their lives but they are also saving the lives of their children.

Changes in Gender Inequality in Canada in Sports Essay

Society expects males and females to fulfill specific gender roles – â€Å"attitudes and activities that society links to each sex†. Males are expected to be ambitious, strong, independent and competitive, which â€Å"encourages males to seek out positions of leadership and play team sports†. And females are expected to be deferential, emotional, attractive, quiet and obedient, â€Å"supportive helpers and quick to show their feelings† (Macionis and Gerber, 2011:300). These traditional stereotypes have been challenged and confronted by many women and feminists, and in this paper we are going to look specifically in sports and physical activities. My thesis statement will be that gender inequality has been decreasing over the last 100 years. Women were slowly starting to participate in all sports which were considered to be masculine, and were only available for men to enjoy. One of the first factors which could be linked to the emancipation of women in sport in late 1800 – early 1900s is the safety bicycle. It not only caused a revolution in women’s fashions: women’s sportswear was finally being designed to accommodate more vigorous activity, but â€Å"was also a â€Å"vehicle† through which women broke with traditions and asserted their independence† (Hall and Richardson, 1982: 32-33). Slowly more organizations, sports clubs and tournaments were opening up for women. In the early 1900s, women started to participate in most forms of sport, but were still prohibited from activities there body contact was possible. Period after the World War I and throughout the 1920s was really exciting for sportswomen in Canada and their fans. â€Å"This often called the â€Å"golden age† of women’s sports, it was time when popular team sports like basketball, ice hockey, and softball became sufficiently organized to hold provincial and Dominion championships; when the best athletes, especially in track in field, began to complete internationally and eventually at the Olympic Games; and when women leaders and administrators took control of women’s sports, claiming they knew what was the best for girls and women, although the advice of the man was still needed† (Hall, 2002: 42). In the 1928 Canadian women have joined Olympics in Amsterdam for the first time for the track and field competition. In the mid 1930s â€Å"depression tightened its grip on Canada and the were signs that the Golden Age was over. Reactionary attitudes towards athletic competition for females was taking hold; commercialized professional sport for men was on the rise, meaning that men’s sports were given priority of access to public facilities. Spectators were drawn away from the women’s games to the exclusively male professional sports like ice hockey, football, baseball; it became increasingly difficult to find sponsors for women’s amateur sport† (Hall and Richardson, 1982: 36). World War II took its toll on both men’s and women’s sports. Although many of leagues continued to exist, nobody took athletics seriously. Olympic Games did not start again till 1948. † Post war conservatism has been described by Betty Friedan: women should desire â€Å"no great destiny than to glory in their own femininity†. Careers or commitments outside of their home were unnecessary for their personal fulfillment and undesirable for the satisfactory performance of the housewife role† (Lenskyj, 1986: 83) For the duration of war women were occupying men’s jobs and were laid off as soon as men returned home to resume the rightful place. It was still alright for women to participate in â€Å"beauty producing† sports like figure skating, synchronized swimming, or gymnastics and as long as they looked pretty and feminine on the tennis, badminton courts, golf courses, and ski hills, they were not criticized. But women athletes which were â€Å"sweating on the basketball courts, softball pitches, ice hockey rinks, and the cinder tracks were suspect, their femininity continually questioned† (Hall, 2002: 109). Participation in school, university and community sporting programs however, was hardly likely to pose a threat to femininity. Basketball continued for the most part to be played by girl’s rules. Softball, an already simplified version of baseball, was in some cases was modified further for girls and women. In the 1960s not only women’s femininity was being questions but also their sexuality. In the 1966 the first official â€Å"sex tests† were introduced, with three gynecologists visual examination to confirm that athletes genital sex was, in fact female. â€Å"The introduction of sex tests coincided with significant advances for women in terms of their participation at the Olympic Games, with number of them increasing dramatically throughout the 1960s and 1970s.† For example at the summer Olympics, the 800 meter running was reintroduced in the 1960s. Women’s volleyball, the first team event for women was introduced in1964, along with pentathlon and 400 meter individual medley, swimming event. The 1968 Olympics in Mexico City six more swimming events were introduced and in the 1972 at Munich, the 1500 – meter run, 4Ãâ€"400 meter track relay, and kayak slalom were introduced. So the number of women on Canada’s Olympic team has increased from 11.30 to 22.6 per cent for the Summer Olympic between 1960 and 1972, and from 21.4 to 38.3 per cent for the Winter Olympic Games during the same period. Sex testing at the Olympics originally was called â€Å"femininity control† and was trying to determine who was genetically female, because prior to that where has been a lot of men who were trying to pose as women, which was only found out after the fact and also women athletes were becoming more â€Å"masculine†, therefore it had to be proved that they were actually females (Hall, 2002: 153 -159).The sex testing did not stop until the 1998 Olympic Games in Nagano. By the mid-1970 all across Canada parents started noticing that their daughters were not being treated the same way as their sons when it came to recreational and sporting opportunities by the late 1970s there has been a lot of sports related complaints of sex discrimination. The majority of these cases were involving young girls who wished to play on all male sports teams. The main value of these human rights cases was to bring public interest, concern and â€Å"pressure to bear on eliminating unequal, sex discriminatory sport and recreation programs† (Hall, 2002: 163) In March 1981 Canadian Association for the Advancement of Women and Sport(CAAWS) was established. It started providing women athletes with funding and support. And finally â€Å"in 1982 women were granted equal protection and equal benefit of the law in the Canadian Charter of Rights and Freedoms† (Macionis and Gerber, 2011: 305). Beginning of the 1990s in the most areas of organizational life including sports, has been a subtle shift from â€Å"equality† to â€Å"equity†. â€Å"Gender equity is the principle and practice of fair and equitable allocation of resources and opportunities for both females and males. This eliminates discriminatory practices that prevent the full participation of either gender† (Larkin and Baxter, 1993: 4) In the past decade Canadian women are participating almost in all sports on competitive levels. â€Å" In 1998, in Nagano, Japan, women’s hockey was an official Olympic sport for the first time, and world of Canadian women’s hockey changed forever. The game that originated in Canada had become part of our collective identity, continues to be our most popular sport and it is now played by women – legitimately!† (Macionis and Gerber, 2011:320) Canadian women Hockey team has won Olympic gold medal 3 times in a row: 2002 Olympics in Salt Lake City, 2006 Olympics in Turin, and 2010 Olympic Games in Vancouver. Their achievements have been absolutely amazing. They have showed that they force to be reckoned with. They actually have done better than Canadian male Olympic team. In this 2012 Olympics Games in London, England for the first time women’s boxing is going to be introduced. And there has been controversy of women should wear shorts or skirts. The Amateur International Boxing Association (AIBA) requested that female boxers wear skirts so that would make them more elegant – on the trial basis – at the European Championships and for permanent use in the Olympics. One of Canadian boxers Elizabeth Plank, told Teddy Katz of CBC radio sports news this January: â€Å"Forcing women to wear skirts, I think, it’s sexism†. Eventually AIBA have decided to have optional for female athletes to decide if they want to wear skirts or shorts. (CBC Sports) As we are able to see gender stereotypes and discrimination in sports still exists. Women still do not get as much Media coverage as men do. They are still making smaller salaries than their male counterparts. Women athletes still have to look beautiful and attractive or they might be stereotyped as being lesbian, butch or masculine, if there are not. What about the future? It seems that future for Canadian women athletes seems bright. There are much more opportunities that are coming up for women in sports, for example in the Winter Olympics in Sochi in 2014, Russia – the addition of women’s ski jumping has been approved. Women are going to keep fighting for the equal rights to participate in sports events without being criticized to be unfeminine. Daniels (2009) argues that femininity –masculinity divide still prevents women athletes to be taken seriously in their sports. And the best would be to embrace the polygendered way of being, which emphasizes the similarities between women and men, and that way female athletes will be given the chance to achieve their full sporting potential and be judged for performance, rather than their appearance.
