Global Warming Poses Threat to Ski Resorts in USA Essay Example for Free

Global Warming Poses Threat to Ski Resorts in USA Essay The American west is marvellous, it is large with grand landscapes and mountains reaching to the sky . The plains unfold to the horizon and the vistas present an unimaginable panorama. Just like any where else in the world, water is an essential element to life here but it is scarce hence creating the wests vulnerability. Precipitation is generally low and cannot support agriculture it is for this reason that agriculture is only possible through irrigation. This precipitation is not only scarce but scarcest in the summers when it is mostly needed but falls disproportionately and mostly in the mountains in the winter. The only saving grace is that in winter it precipitates as snow and stays as snow packs throughout the winter. It is on the basis of these weather patterns that the winter sports tourism is established. This industry has served as the main economic driving machine of the west and other other areas for decades. However, changing climatic patterns and global warming has emerged as a serious threat to the existence of the winter sports industry. Projected increases in average global temperatures due to increases in green house gases in the atmosphere has been incriminated in widespread glacial and white cap decreases, ocean level rise and warming but most importantly in the reduction of snow cover and the decrease in the duration of winter tourism. The unpredictability of the future and the climate sensitive nature of winter sports tourism has led to many initiative aimed curbing the increase in green house gases and consequently making snow available. Introduction Compelling evidence suggests that global climate has been on a progressive change since the industrial era and is projected to continue over the 21st century and beyond. Global warming and climate change is an unequivocal phenomenon. Global mean temperature has been on the increase with an approximate increase of 0. 760 C between 1850-1899. the same increase has been found between 2001 and 2005. This means that global predictions of temperature bear a 90% probability (IPPC. Climate Change and Tourism, 2007). These increases in average temperatures are a direct result of human activities that increase the concentrations of green house gases in the atmosphere. The extent of these discernible human influences have also extended to other climate change aspects such as temperature extremes, changes in wind patterns, continental average temperatures and ocean warming. The same is applicable to the widespread glacial and white cap decreases coupled with warming of the ocean surface temperatures, the result is a sea level rise of approximately 1. 8mm yearly from 1961-2003 and approximately 3. 1mm yearly from 1993-2003. The resultant effect of biological response in ecosystems and species diversity presents an unpleasant scenario and these statistics are recorded in virtually every continent. It is projected that the probability of increase in global temperatures will further accelerate green house gas emissions at the present or above the present rates. The prediction pushes overall global temperature rise by 1. 80C -4. 00C. Assuming that the atmospheric concentrations of green house gases are stabilized, the warming effect would still continue due to the levels of green house gases from past emissions and the consequent thermal inertia of oceans. The biological response would also be extrapolated to future centuries even if the levels are stabilized at the present concentrations today. The discernible manifestations worldwide will be hot temperature extremes, extreme heat waves, heavy precipitation, peak wind speeds and precipitation in tropical cyclone events and an additional heavy precipitation associated with increases in tropical sea and surface temperatures. Together with these climatic changes extra tropical storm tracks are projected to shift towards the poles. All these changes together with the decreases in show cover will continue into the future. The economic and environmental risks are unfathomable and would effectively impede nations strides towards the achievements of sustainable developments. However, there is hope that if precautions and measures are taken to reduce green house gases today the high costs of environmental and economic destruction and disruption can fairly be mitigated. This calls for lifestyle changes, economic policies and regulations and international efforts that not only help reduce the causative agents of climate change and global warming but also foster adaptation and mitigation measures to meet the challenges of climate change. Climate change and Tourism Climate change, especially global warming has grown to be a pivotal issue in the development and management of tourism. The relationship between the environment, climate and tourism sector is currently a highly sensitive economic matter. Climate change is increasingly driving tourism development and decision making, changing tourism destinations and even tourist tastes. Tourism sector remains a non negligible contributor to climatic changes. GHG emissions from transport and accommodation must be reduced in accordance with international standards. Tourism sector cannot address the challenges of climatic changes themselves and in isolation but they can only do this in the context of sustainable development and the broader international development agenda. Tourism and the sustainability of tourism destinations is dependent on climate variability. The length and the quality of seasons as well as destination choice and the level of tourist spending are all determined by climate change. Climate change and winter sports Winter sports constitute a very source of income and the reliability of snow is a key element in the touristic offer. Skiing and snowboarding are the most common forms of writer sports but others such as snow hiking and cross-country skiing also depends on the reliability and the availability of enough snow. Mountainous areas are always very sensitive to climate change hence less snow, melting permafrost, receding glaciers and extreme events such as landslides. Additionally climate change shift mountain fauna and flora. These effects pose a direct threat to ski resorts in the United States. Lower earnings in winter tourism will only serve to exacerbate economic disparities that exist between the alpine regions and the more developed urban areas. These changes will also increase the risk of only skiing at high altitude up the mountain. If this was to happen there would be an intense concentration of sports activities in certain regions as well as further putting pressure on the environmentally sensitive high mountains. The extrapolation of the effects of global warming on winter tourism extends to the viability of the mountain cable way companies that use the availability of snow as a prerequisite for their financial stability. Without snow or enough snow the profitability of the ski industry is impossible. The absence of snow in the mountains will be like having a summer without a sea. The variability of the winter season with response to climate change will deny the winter sports industry the right levels of snow at the right time. These forecasts are a necessity in planning for trips at shorter notices especially the weekends (Rolf Burki et al, 2003) Studies undertaken in Canada, Australia, New Zealand, Australia, Switzerland and the United States to establish the impact of climate change on the tourism sector show severe implications especially to the winter sports industry. While some regions with high technological advances like adaptation strategies (artificial snow making) will maintain their tourism, others unable to adapt the expensive technologies will lose out. These transitions in business volumes will not only be driven by limiting snow levels but also the fact that skiers respond flexibility to snow conditions. During a snow poor season, 49% of skies are most likely to change to a resort that is fairly more snow reliable, 32% would reduce the frequency of skiing and only 4% would give up the sport. Coupled together with the fact that climate change has a direct effect on the number of ski days, those unable to adapt to expensive technologies will be disadvantaged and pushed out of business. (Rolf Burki et al, 2003). Snow resorts not concentrated in snow reliable high altitude areas will be forced to withdraw from the market because of decreasing levels of snow. For transport industries that will offer access to high altitude areas (sometimes higher than 200m) business prospects will be good due an expected increase in skiing at the high altitudes. The effect of this will be quantitative expansion of the high altitude skiing resorts hence eliciting a negative environmentally feedback effect caused by disruption of the ecologically sensitive high altitude mountain regions. Presently, this expected expansion to high altitude areas has been the theme of many concept studies that influence the opening up of High Mountain (Breiling and Charamza, 1999) It is for these effects of climate change that during a recent campaign in Portsmouth, N. H, Barrack Obama the Democratic Party presidential candidate reiterated that there is need to address the urgency of global warming on the ski industry. He said that global warming is not a future problem but a present one. This problem has made New Hampshire to have shorter sporting seasons and people are losing jobs. He further reiterated that residents of North America ski areas together with their customers should work hand in hand to change their energy spending. habits and resort to green technology if they were to prevent climate caused melt-downs (Laura Bly, 2007) Resorts have started investing in sustainable seafood practices, local food supplies, biodiesel powered snow cats and embracing the use of more energy efficient snow making equipment. To achieve this, campaigns on global warming and discounts are being offered to guests who come in hybrid cans. What is even more impressing is that resorts have taken the challenge of campaigning for these changes as well as acting as advocates for intergovernmental change. Effects of global warming have also been reported in Burlington Vt. The city is usually carpeted in December but unfortunately changing climatic conditions has created a mild situation where snowfall is meager just an inch thick. The temperatures are becoming warmer and fewer trails open. However, these fears have been allayed by the optimism of the meteorological department prediction that the season will progress as Christmas approaches. According to Michael Berry; president of the National ski Areas Association, the potential impacts winter recreation, the mountain ecosystem and the way of life of residents in these areas cannot be ignored. Global warming has a direct and profound effect on the ski business as it depends solely on the variability of weather. To drive this process of change, the association has adapted a policy to regulate and control climate change. The reduce, educate and advocate approach was adopted to help in the fight against global warming. Key in the policy is a call to ski resorts to work towards the reduction of green house gas emissions individually and collectively, educate the public and guests on the potential impacts of climate change to writer sports industry and be the advocate in pushing for institutional and regulatory changes aimed at curbing greenhouse gas emissions (Michael Berry, 2007). To this end almost half of the 59 ski resorts, who have purchased renewable energy credits or utilized green energy for their lifts and other facilities are 100% green powered hence reducing carbon dioxide emission by 427,596,000 pounds an equivalent of planting almost 17 million trees. Customers are encouraged to offset their emission and work towards increasing green energy use in their home. Generation of renewable energy through on site solar projects or micro hydro power projects and wind energy has greatly increased with Jimmy Peak Mountain Resort in Massachusetts installing the first wind turbine powered ski area in August 2007. Resort vehicle fleets are now using alternative fuels like biodiesel, they also provide or promote car pooling or mass transit use. Ski resorts are being built using green building techniques and retrofitting existing facilities all with the aim of saving energy. Though an outreach program called â€Å"Keep Winter cool† millions of people have been educated on global warming and encouraged to institute lifestyle changes to help curb global warming. Specific Impacts of Global Warming on Winter Tourism . Snow The financial viability and stability of the winter sports tourism industry solely depends on the availability of sufficient snow. Less snow pack is caused by higher average temperatures, on the other hand if there are extremely low temperatures at night then it follows that there is likely to be an average increase in daytime temperatures. In both cases the resultant effect is less mountain snow cover and a reduction in the duration of cover. (Stephen Saunders et al, 2005). This means that recreation will be shortened and the snow will be slushier. The big difference to earlier situation where snow cover was considerably reduced is that, the capital intensity of the winter sports tourism will be considerably high. When this is analyzed in the context of profits from ski dependent businesses, taxes from local and state governments, the financial prospects of industries in the winter tourism sector look bleak. However, the most important link between climate change and mountain tourism is less snow and, as a consequence, less earnings in ski tourism. Glaciers Statistics all over the world point to the fact that there is a general retreat of glacial cover all over the world. Taking Switzerland as an example, since 1850, the Swiss glaciers have lost slightly more than 25% of their surface. If this was to continue in the future, by 2030, approximately 20% to 70% of the total Swiss glacial cover will disappear. This is a real problem for the ski industry not only in Switzerland but across the world as ski tourists will resort to other countries with snow availability. The effect of this trend will be putting more pressure on the existing ski facilities as well as acting as an incentive for investment in high altitude areas. Permafrost Melting of permafrost due to global warming makes mountain areas vulnerable to landslides. Transport facilities such as the mountain cable way stations, the lift masts and buildings become instable. Them costs incurred in bracing and anchoring such buildings when permafrost melts are extremely high. Hiking and climbing in these areas is also made more dangerous hence the loss of revenue due to potential risk of injury like rockfall or other health outcomes. Despite of cries over decreases in snow levels in the future, there is a possibility of winters with heavy snow like that of 1998/1999 that brought a great deal of losses in the winter tourism industry. The avalanche winter destroyed mountain cable ways, ski-lifts and chair lifts. The expenses incurred on sow clearing and the overall loss incurred was in excess of US $ 130 million. Adaptations for the future ski industry should therefore inculcate these historical weather unpredictability patterns in improving the industrys financial viability. Adaptations and Strategies Used by the Tourism Industry to Mitigate Against the Impacts of Global Warming All tourism representatives at political,organizational, entrepreneurial or operational level have been in the forefront in pushing for adaptation strategies to curb climate change and help mitigate the potential effects of global warming. The experiences that project what is going to come in the future are prevalent today and is widely accepted that snow deficient conditions will determine whether winter tourism will remain a viable economic activity. To achieve this a multi sectoral framework that consists of the National Ski Areas Association(NSAA), Natural Resource Defense Council (NRDC), the federal government through the Senate Environment and Public Works, state stakeholders and other non governmental civil society organizations have developed a Climate Change policy aimed at reducing the concentrations of green house emissions. Ski resorts have been encouraged to adopt safe and efficient energy usage through the exploitation of renewable energy resources. It is this concerted effort in mitigating climate change challenges that also saw the support and endorsement of McCain/Lieberman Climate Stewardship Act to spearhead the fight against global warming. Specifically these attempts will help stabilize the US$ 5 billion mountain resort industry that currently offers employment to 165,000 people. Despite the existence of facts that predict radical effects in the industry, some argue that climate change issues are very exaggerated and politicized by science and the media. They argue that even though the effects could intensify problems in the industry, the majority of resorts in medium and high altitudes will be barely affected. Discussions should yield strategies that take into account the accuracy of statistical data disseminated on climate change and critically analyze the potential consequences. These issues should further be analyzed with reference to the global competition in the winter tourism sector. The facts that accrue from these forums should then be integrated in the construction of artificial snow flaking facilities, extend existing ski runs. Opening of high altitude ski resorts (2000-3000m)should be guided by the potential ecological effect. Climate change should not only be viewed as a negative challenge to winter tourism but also as a catalyst to drive radical structural adjustment and change. These developments should take into account the present risks and opportunities as well as foster development that is in line with the strive for environmental and socio economic sustainability. This will create a highly competitive market where customer preference is not only driven by snow availability but by the efficiency of service in some very high end but smaller less extensive resorts. Such top resorts will offer attractive offers for skiing tourists and hence reduce attention on expansive developments with less attractive offers. Artificial Snow making This is an ubiquitous strategy that is widely employed to mitigate the risk of climate change. Since its inception in 1953 at the Grossingers Resort in New York, it has grown to become the principle in the ski industry with an approximate 95% of the resorts engaged in the strategy. Its success has mainly been driven by its invaluable superior nature that offers a complete substitute to natural snow fall as well as making it possible to extend skiing durations(Daniel D. D. McGill, 2007). However, this technology is heavily dependent on temperature and is only effective in cases at low temperatures. Technological advances has seen the reduction of labor costs through the use of snow guns operated by computers. Snow making utilizes vast volumes of water and therefore the availability of water must be guaranteed for efficient blanketing of a large resort. Weather Derivatives. These are weather risk management tools structured to enable ski resorts make appropriate and informed decisions. They can be structured on snow fall temperature according to the customers specifications. Other factors that can be utilized to mitigate the effects of global warming include r4evenue diversification, cloud seeding and marketing to insulate the resorts against variability of weather by enabling them to maximumly capitalize when the weather is excellent. Conclusions Climate change and global warming remains will continue to remain key challenges in the winter tourism industry especially the ski resorts. Less snow, less glaciers and extreme weather events such as landslides are the key determinants of the future viability of ski resorts. Strategies instituted to meet the challenges of climatic change and mitigate the impacts of global warming can never be successful if implemented in isolation. It is commendable fact that the skiing industry has adopted sustainable building techniques,inculcated green principles and technology in their operations among others. These precedents are admirable but we have to admit that when taken in the global context, these measures do very little in stemming the worrying tide of global warming whose effects are felt indiscriminately. Global warming is a worldwide problem and therefore all the measures undertaken by the tourism industry must be in line with national and international guidelines that aim at reducing greenhouse gas emissions. In the future, tourist developments will not only be evaluated and judged with respect to their environmental or socio-economic compatibility and viability but they will also be assessed with respect to the climate-compatibility angle.

Eccentric and Concentric Bench Press Comparison

Eccentric and Concentric Bench Press Comparison Introduction Resistance training is an exercise modality that can be defined as a movement working against an external load resulting in physical adaptations (McArdle, Katch Katch, 2014). It is utilised by many as a means of increasing muscular strength, improving athletic performance, reducing the risk of injury and to maintain a healthy lifestyle. An average resistance training programme would incorporate a variety of static and dynamic movements whilst under an external load (Jones, 2009). Whilst the muscles are static, the fibres are in a fixed state and no change in length occurs. However, in a dynamic movement muscles go through a shortening and lengthening process. The concentric phase involving the shortening of muscle fibres, and the eccentric phase involving the lengthening of the fibres. Current literature proposes that eccentric and concentric training illicit different training responses and therefore could produce different muscular adaptations (Rosete et al. 2015). Although there are a variety of methods to provide resistance in a training sense, traditional exercises involve moving a load in opposite directions (i.e. push/pull) where there is a shortening (Concentric) and subsequent lengthening of the muscles (Eccentric). Proske (2001) describes the concentric phase as the actions that initiate movement, whereas the eccentric phase slows movement or brings it to a halt. Some research indicates that muscles acting in an eccentric fashion produce more force than when working concentrically. Other research shows eccentric movements have different fatigue patterns to concentric movements which could explain their apparent superiority. The intended purpose of this proposal is to quantify if concentric bench press yields less strength than eccentric bench press, measured via a 1 rep max max test. Literature Review As previously defined, resistance training is movement working against an external load resulting in physical adaptations. The health benefits of resistance training are widely documented with most of the literature reporting on musculoskeletal adaptations. Recently there has been an emergence of literature detailing other outcomes of resistance exercise such as benefits for metabolic disease (Jurca, 2005), bone density health (Lohman et al, 2003), all-cause mortality (Metter et al, 2002), mobility (Janssen et al, 2002) and quality of life (Levinger et al, 2007). Furthermore, resistance training provides a means of exercise for people whose current cardio vascular based regimes such as jogging or swimming have become too difficult. Based on these findings, resistance exercise is now considered an imperative component of a regular training program. The eccentric phase of a muscle action is when the force generate by a muscle is inferior to the external load. This is characterised by a lengthening of the muscle even though an actin-myosin cross bridge is formed. In this instance when actin separates from myosin it is regarded as a mechanical separating rather than chemical (Flint Hurst, 1978). In contrast, a concentric muscle action involves the actin filaments being pulled over the myosin filaments as the muscle shortens. This is commonly known as the Sliding Filament Theory (SFT).ÂÂ   SFT refers to the movement of actin and myosin sliding over one and other. (Baechle Earle, 2000). Cross bridges are separated through the splitting of an Adenosine Tri Phosphate molecule, thus making it a chemical reaction rather than mechanical. This is a more energy dependant process and should result in less trauma to the muscles. Eccentric muscle action, when used in a resistance training setting has been shown to improve neural activation (Enoka, 1996), muscular strength (Hortobagyi, 1996) and increase muscle size (Vikne et al, 2006). Enoka (1996) goes on to suggest that muscles become more resistant to fatigue when working eccentrically. Placing emphasis on the eccentric phase of an exercise has been proven in some studies to be effective at improving strength than an even split of eccentric/concentric (Brandenburg Docherty, 2002). Research has been conducted to examine the physiological and metabolic effects of concentric actions versus eccentric muscle actions. A study by Hollander et al, (2008) examined if contraction type (Eccentric/Concentric) or load (Absolute/Relative) has a greater metabolic impact on resistance exercise. Seven resistance trained men were included in the study. Their concentric 1 rep max determined for several exercises then their 1 rep max for eccentric was estimated at 20% greater. On completion of the initial 1 rep max testing, participants completed a further 2 bouts of maximum lifts in a random order: concentric only lift and an eccentric only lift. They were then assessed on rating of perceived exertion, pain rating and heart rate. Tests were conducted to take samples of blood PRE/POST exercise, and 15 minutes after exercise had finished to identify lactate and cortisol levels. To analyse the data, a repeated-measure ANOVA was used. No differences were noted between concentric and eccentric trials for pain rating and perceived exertion. Heart rate was significantly higher in every exercise except lat pulldown. Levels of lactate were significantly higher directly post exercise and 15 minutes after following concentric training compared to eccentric training. The study shows that at a relatively lower intensity, concentric and eccentric training show similar rate of perceived exertion pain perception under a relative load (%eccentric1RM= %concentric1RM +20%).ÂÂ   This suggests that you can overload the eccentric phase of an exercise with 20% more than the concentric phase and the body is not negatively affected. Heart rate was maintained at a lower threshold throughout training apart from in one instance despite the eccentric phase holding a 20% greater load. This potentially indicates that eccentric exercise could be deemed as a safer modality of exercise than concentric Enoka (1996) conducted a study highlighting the differences in concentric and eccentric muscle actions in regards to neural activity. Previous studies suggest that neuralogical factors can augment strength gains in trained (Edgerton et al, 1986) and untrained individuals (Komi, 1986) whilst also increase the efficiency in which they can lift sub-maximal loads (Ploutz et al, 1994). It is also noted that neural factors increase the synchronization of motor units (Milner-Brown et al, 1975). A motor unit is defined as motoneuron and all its associated fibres (Bachle Earle 2002). An action potential is passed through the motor neuron, this releases a hormone which passes across a neural junction resulting muscle fibre activation (Baechle Earle, 2000). To increase the force generated by a muscle, motor unit activation must increase frequency, or recruit more motor units at once. Usually motor units activate in a uniform sequence, inferior unitsÂÂ   activate first with superior units coming in to play when the external load becomes too great, commonly termed as the size principal (Baechle Earle, 2000). In order to generate maximum force, it is necessary for all of the motor units within a muscle to activate. In most people the size principle applies, lower threshold units being activated then the higher threshold as the load increases. Some research suggests that resistance exercise increases the efficiency that a person can recruit the higher threshold motor units (Sale, 1987). Enoka (1996) goes on to suggest that this differs for muscles working eccentrically. Research has identified that it is not likely to recruit all motor units during maximum eccentric contraction despite that fact that eccentric strength is usually 20% greater than concentric (Tesch et al, 1990). Aims Previous literature suggests that the strength of the eccentric portion of an exercise can be anything up to 120% greater than that of concentric (Hortobagyi, 1990). Current literature also proposes that eccentric and concentric training illicit different training responses and therefore could produce different muscular adaptations (Baechle Earle, 2000). From the previously mentioned literature, the following was hypothesised: Eccentric 1 Rep Max bench press will yield greater strength than concentric. Objectives The main objective of this proposal is to quantify the differences in eccentric and concentric bench press scores. Methodology Participants Twenty six males between the ages of 18 and 31 who have been taking part in resistance training for over 1 year volunteered for the study. For the purposes of this study resistance training experience is defined as having regularly trained bench press( 1p/w) over the year leading up to the study. Volunteers for the study where students recruited from sport and exercise science classes at The University of the West of Scotland, Hamilton Campus. It was required of the students involved in the study to firstly complete a Physical Activity Readiness Questionnaire to ensure that they were physically fit enough to engage in the study. It was also required of the students to complete an Informed Consent document outlining how the study would be carried out, how it affects them and highlighting that they have the right to withdraw themselves at any time. Exclusion criteria from the study included: orthopaedic injuries, hypertension, cardiovascular issues and abuse of anabolic agents. Current dietary intake will not be monitored throughout the study, but it will have to remain consistent throughout its entirety. Once the study begins, participants may not take part in any resistance training out with study. The assumption is made that all participants will follow all testing protocols relayed to them for completion out with the laboratory. The participant is also required to abstain from exercise that is greater than the needs for daily living during the testing period. They must also refrain from taking any ergogenic supplements or making dietary changes throughout the testing period. Protocol The study will consist of 3 testing sessions over an 8-week period. Testing will be conducted in the strength and conditioning laboratory in the University of the West of Scotland, Hamilton Campus. Participants will be split into 2 even groups for testing, concentric and eccentric. Participants will be prompted to complete an informed consent document providing their approval to take part in the study. Once the document is completed and reviewed, anthropometric measurements will be taken: weight, height and body composition. Following anthropometric measurements, participants will perform a cardiovascular warm up on a cycle ergometer for (90RPM 5 minutes). This will be followed by an incremental warm up protocol for bench pressing (10,5 and 3 repetitions). The weight used here will be self-selective and should increase with every set (Baechle Earle, 2000). All three testing sessions will include the cardio vascular warm up, bench press warm up followed by 1 Rep Max testing in eithe r eccentric/concentric bench press, depending on what group the individual has been placed in. Participants will be allowed to have a few practice attempts with an unloaded barbell to familiarise themselves with how the testing will operate. The concentric group will perform their lifts by lying supine on a bench from the chest until they can fully straighten their arm, extending the elbow. The bar will be lowered down to their chest prior to each rep to ensure that only a concentric muscle action is being measured. This will be done via a pulley system and two additional spotters positioned at either end of the barbell. When the participant is unable to completely straighten the arms to complete the concentric bench press, the repetition will be deemed a failed rep. The eccentric bench press will involve the slow and controlled lowering of a barbell from full extension down to the chest. It should take the participant three seconds to perform this movement and tempo will be kept with a metronome to help to identify successful reps. On completion of a rep the barbell will be returned to the original position via pulley system and assistance from spotters. If the participant is unable to control the descent of the bar, allowing it to touch their chest before the 3 seconds ends the repetition n will be classed as a failure. To ensure that all the participants are safe, stringent measure will be taken. Spotters will be used during all exercise sets, warm up and testing. The pulley system will be lowered to the appropriate height for each user, this will be marked to ensure consistency with the operator. Chalk will be made available on request to reduce the likelihood of the barbell slipping from the hands. Statistics All data collected in the study will be analysed using an SPSS software. The data will be initially inspected to make sure it is acceptable. The mean and standard deviation will be calculated using a paired T test which will help to identify if there is a significant difference between concentric one repetition maximums and eccentric.

Implementation of Lean Systems in an Organisation

Implementation of Lean Systems in an Organisation Abstract The report describes the significance of value chains, lean system, lean production, and the concepts of eliminating waste from an organisation. Following this the report also illuminates the use of lean productions and lean services in an organisation called as Baxter Healthcare Corporation which manufacture global medical products. It also enlightens the essential goals of implementing lean systems in an organisation. Primarily, a brief overview is given on Operation management. A short explanation about water value stream mapping (VSM) exercise held at a South-eastern United States facility.. Using Lean practices, sometimes integrated with an environmental focus, the company was capable to double in size and revenue while keeping its total waste generation close to 1996 levels is discussed. The Corporate social responsibility and the Porters value chain is described in detail. And at the end a summary of the report is given. Definition A fusion of Japanese and US management principles focusing on the reduction of: waste, inventory and customer response time. http://managers-net.org/Lean.html General Introduction In 2001, Baxter Healthcare Corporation, a worldwide leader in the manufacture of global medical products, was worried that its environmental track per unit output, a key target of efficiency, was rising. To battle this, the company adopted a congregation of business and manufacturing methods. One worked: Lean Manufacturing. As Baxter began to see waste generation drop with the deployment of Lean, the environmental engineering group realized that environmental enhancement was habitually an inadvertent benefit of Lean Manufacturing. In order to make best use of this benefit, this group began to hunt for ways to additional mix environmental metrics and performance into traditional Lean Manufacturing tools. By means of Lean practices, at times integrated with an environmental focus, the company was able to double in size and revenue though keeping its entire waste generation close to 1996 levels. Baxter has been so victorious at sinking waste that many of its biggest facilities are now classified as small quantity or conditionally excepted little magnitude generators under EPAs hazardous waste rules. This learning highlights a water value stream mapping (VSM) exercise held at a Southeastern United States facility. Baxters Key Lesson Learned Based on a value stream mapping (VSM) incident held at this provision, as well as other interconnected events, Baxter has developed a amount of key lessons for building value stream mapping work: The targeted aspect (energy, water, materials, etc.) should be correlated to facility challenges and the company strategic plan. For example, if the facility has boilers or uses steam or distilled water, it should discover opportunities in water and its related energy. In ISO 14001 terms, the facility should be targeting one of its environmentally important aspects. A cross-functional team is crucial to successfully identifying and understanding the challenge. Upper management support is decisive for the follow-up on implementation. |Excellent, perfect data is also crucial. Data can be gathered in a number of creative ways, as simple as a bucket and stopwatch (water), a clip-on current reader (energy), or a portable flow meter for water discharge. Several utilities offer these services for low or no cost. If essential, bring in expertise. If expertise is not available in-house, then utilize the various free resources that states provide, such as energy experts, water engineers, etc. Do not rely on Lean consultants by yourself. Lean is a way of seeing and thinking, not merely a set of tools. Lean consultants can be a great source of tools and training, but a facility cannot truly learn Lean without living Lean. The metrics selected should be proper to measure progress in the targeted processes. The team should be prepared to revise or scrap an ineffective metric. Environmental personnel should be given the same representation and responsibilities as other staff. For example, if an operations manager has to make available a monthly report, so should the EHS officer. The environmental staff is an integral part of the team. Baxter Manufacturing Plant, Southeastern United States Baxters solution plants, which manufacture flexible-container IV and peritoneal dialysis products, often use big quantities of water and energy. With steadily growing energy costs and increasing pressure on clean water supplies, these facilities are encouraged by Baxters Corporate Vice President of Manufacturing to diminish water and energy consumption. Plants were particularly encouraged to perform a utilities value stream map. The plant selected for this study is one of Baxters largest facilities. The facility has received numerous honors, including the Shingo Award for Manufacturing Excellence. In its quest for Perfect Processes, the plant actively uses Lean practices. Because the plant gets its water from its own wells, employees imperfectly assumed that water had slight cost associated with it, thus ignoring the energy use and costs of pumping, storing, heating, filtering, and disposing water. Baxter views water waste as an sign of other costly inefficiencies. For example, water waste is often directly tied to excessive energy consumption. Creating the Current State Value Stream Map for Water To assault the water waste challenge, managers chose to use value stream mapping (VSM), one of four key approaches Baxter uses to incorporate environmental metrics into Lean practices (see appendix). This marked the first time that VSM was used at this facility to track a material resource-in this case, water-through the entire production process. To generate the VSM, a diverse team was preferred that integrated utility and water experts as well as maintenance, production and EHS personnel. The value stream maps and associated implementation plans were developed over a three-day event. The opening day began with introductions, followed by an explanation of the format and process of the VSM event. Then, the mapping began. Using sticky notes, the team graphically walked through the whole production process, highlighting water usage and major processing steps. The first pass of mapping was high-level and general; each subsequent pass would add more detail and refinement. During the second round of mapping, the major processes were wrecked down into sub-processes. Then, using the capability of the participants, the water volumes, cycle-times, value-added calculations (e.g., cost of pumping the water to the next step) and other relevant information were added to the map, with costs normalized per 1,000 gallons. The team also listed the triggers that caused each process step to initiate (e.g., an empty tank might trigger a rinsing/flushing process step). In addition, the team emphasized dissimilaritys between what must happen in theory versus the actual practices on the floor. For example, although standard operating procedure (SOP) was to rinse the floors and surface areas of certain rooms following a shift, frequently the whole room, together with the walls, was rinsed, thus wasting water. Emphasizing the dissimilarity among procedure and practice allowed waste to be better identified, with some SOPs tagged for further evaluation at a later date. The outcome of the mapping was the current state value stream map, a credible outline of the destination, use, value, and waste of the water throughout the production process. Metrics The team then deliberated on which indicators and metrics to use to estimate the water usage. They understood that the accurate choice of metrics was critical to the VSMs success. The option of indicators and metrics had to be consistent with Baxters strategic objectives as well as capable of measuring progress relative to the opportunities developed through the VSM. For this VSM, the key metrics incorporated costs (e.g., the dollar value of energy used to process the water) and water volumes. The amount of water introverted from the on-site well versus the amount of product produced was an additional efficiency metric. In addition, the team had to be equipped to adjust or reinstate these indicators and metrics if they proved ineffective in practice. Ranking Opportunities Through the VSM, the team recognized and prioritized 96 opportunities, with lots of graphically represented by starbursts. These opportunities were categorized by the estimated length of time for implementation (e.g., 6 months, 12 months, 24 months) and potential for improvement. Then, they were visually plotted on a grid with the magnitude of the potential profit on the Y-axis and ease of implementation on the X-axis. After all the starbursts had been appraised on this grid, the results were transferred onto various future state timetables, to prioritize the opportunities and plan for their implementation. Generally, starbursts that can be implemented within 6 months require little or no capital investment (although some may require further analysis to accurately gauge potential benefits). These starbursts are often the first priority for implementation, because of their high return on investment (ROI). Then, the team created three future state VSMs (6 months, 12 months, and 24 months) that incorporated the prioritized opportunities. New teams were created to coordinate the changes. These teams were composed of a mix of personnel that had proper knowledge of the processes involved as well as a solid awareness of how each chosen process fit within Baxters strategic objectives. As some members of these new teams did not participate in creating the VSMs, (for example, quality personnel) it was important to ensure that they all understood the strategy and methods behind the VSM effort. The teams developed specific timelines for implementing the changes using traditional Lean techniques, like kaizen. Projected Savings At the end of the event, Baxter had an action plan that should save 170,000 gallons of water per day and $17,000 within 3 months, with minute or no capital investment. The plan also eliminated the require to expand the plants wastewater treatment plant. Also, since the event, reciprocally the head utilities manager and plant manager have been promoted to positions in the corporate office. Because Baxter makes medical products, changes in a production process might conflict with FDA requirements. Any costs associated with pursuing an adjustment in those requirements would affect the production changes ROI, and thus, its implementation priority. LONG TERM SUSTAINABILITY Long-term sustainability is a business thought that has gained considerable attention following revelations about global warming and dwindling natural resources. At its mainly basic level, long-term sustainability suggests that a company will progress its odds of survival in the future by ensuring that resources used by the business are responsibly managed and maintained. According to a 2010 study by the United Nations, the vast majority of corporate chief executive officers (CEOs) believe that long-term sustainability is a major factor in long term success. The business practices that have fueled the modern global economy were not developed in a time when environmental impacts were understood or even gravely considered. During the Industrial Revolution, when huge scale business truly began to figure the globe, science had not yet developed a extensive means of measuring environmental damage. Yet while environmental science made grand strides in the 20th century, small levels of infrastructure and gaps in communications meant that information about commercial and environmental exploitation in developing nations frequently went unreported or unnoticed for years. As the global economy has developed, so too has a sincere worry for the sustainable use of resources and the practical management of the environment. Long-term sustainability requires a broad point of view as to the impact of doing business.One of the major concerns with the concept is that regulatory measures are often vague and subject to vary. There is certainly an element of threat in long-term sustainability investing, but proponents quarrel this threat should be combated by getting involved in sustainable practices immediately. By proving that a company is interested in protecting resources and conducting business responsibly, the owners of that company stand a higher chance of being involved in or consulted by regulatory committees that will determine future practices. The larger point of long-tern sustainability suggests that, at the bottom level, people are the most essential resource. By ensuring a livable, sustainable environment for humans, companies anticipate to ensure a profitable and sustainable environment for business. Corporate social responsibility Corporate Social Responsibility (CSR) is a conception in the business world. In the late 20th century, a growing number of corporations began to consider about their impacts on society at large, primarily because consumers became extra aware of corporate activities around the world. Many of these corporations decided to get on on Corporate Social Responsibility programs designed to counteract some of their effects on the world while also generally improving corporate practices. CSR has both fans and detractors, as one might visualize; the truth that the issue has become so publicized is viewed as a positive open by many people on both sides. A company which has decided to establish a Corporate Social Responsibility program generally consist of a discussion of the program in its mission statement and code of ethics, making the existence of the program transparent to stockholders and other interested parties. Most corporations also contain a CSR department, which handles the companys social programs and make sure that the companys efforts in the field of Corporate Social Responsibility remain in the eyes of the public. The possibility of a Corporate Social Responsibility program tends to be most varied. Many corporations begin at home, by trying to include conditions for their employees, with offerings like higher wages and health benefits. The next step often addresses corporate suppliers, both at home and abroad, with a focus on creating a sustainable supply chain without the exercise of child labor and other ethically questionable practices. Many corporations also insert a charitable aspect to their Corporate Social Responsibility programs. For example, a company which sells coffee may sponsor community development initiatives in coffee producing regions, while an oil company might contribute to habitat restoration in an region historically used for resource extraction. Other companies simply contribute huge amounts of funds to charities of choice, commonly finding charities which tie in with their own work. Fans of CSR suggest that these voluntary attempts on the part of corporations show a genuine aspiration to do business in an ethical and responsible way. Some more cynical fans also point out that corporations known for their CSR programs tend to retain employees longer and to have the pick of the crop when it comes to employees and suppliers, thanks to an interest in ethical business practices among many new graduates and small companies. Furthermore, because Corporate Social Responsibility is a growing topic of interest, companies which tout such programs frequently perform well on the market, with consumers actively seeking out their products. Detractors trust, however, that Corporate Social Responsibility is simply a smokescreen or window dressing which coats up more egregious issues. By putting their moral initiatives at the forefront, companies can bypass a grand deal of consumer concern. For example, an automobile company may distract consumers with an ad campaign about an environmentally sustainable manufacturing plant, while continuing to produce extremely inefficient vehicles which rely on fossil fuels. The Value Chain The term Value Chain was used by Michael Porter in his book Competitive Advantage: Creating and Sustaining superior Performance (1985). The value chain analysis describes the activities the organization performs and links them to the organizations competitive situation. Value chain analysis describes the activities within and around an organization, and relates them to an analysis of the competitive strength of the organization. Therefore, it evaluates which value every particular activity adds to the organizations products or services. This idea was build upon the insight that an organization is more than a random compilation of machinery, equipment, people and money. Only if these things are arranged into systems and systematic activates it will turns possible to manufacture something for which customers are willing to pay a price. Porter argues that the capability to perform particular activities and to manage the linkages between these activities is a source of competitive advantage. Porter distinguishes between primary activities and support activities. Primary activities are directly concerned with the creation or delivery of a product or service. They can be grouped into five major areas: inbound logistics, operations, outbound logistics, marketing and sales, and service. Each of these most important activities is linked to support activities which help to improve their effectiveness or efficiency. There are four major areas of support activities: procurement, technology development (including RD), human resource management, and infrastructure (systems for planning, finance, quality, information management etc.). The basic model of Porters Value Chain is as follows The term Margin implies that organizations recognize a profit margin that depends on their ability to handle the linkages between all activities in the value chain. In former words, the organization is able to deliver a product / service for which the customer is willing to pay more than the sum of the costs of all activities in the value chain. Some thought about the linkages between activities: These linkages are crucial for corporate victory. The linkages are flows of information, goods and services, as well as systems and processes for adjusting activities. Their importance is best illustrated with some simple examples: Only if the Marketing Sales function delivers sales forecasts for the next period to all other departments in time and in reliable accuracy, procurement will be capable to order the necessary material for the correct date. And only if procurement does a excellent job and forwards order information to inbound logistics, only than operations will be capable to schedule production in a way that guarantees the delivery of products in a timely and effective manner as pre-determined by marketing.In the outcome, the linkages are about seamless cooperation and information flow among the value chain activities. In most industries, it is rather unusual that a single company performs all activities from product design, production of components, and last assembly to delivery to the final user by itself. Most often, organizations are elements of a value system or supply chain. Hence, value chain analysis must cover the whole value system in which the organization operates. Within the entire value system, there is only a definite value of profit margin available. This is the dissimilarity of the final price the customer pays and the sum of all costs incurred with the production and delivery of the product/service (e.g. raw material, energy etc.). It depends on the configuration of the value system, how this margin spreads across the suppliers, producers, distributors, customers, and other elements of the value system. Every member of the system will utilize its market position and negotiating power to get a higher proportion of this margin. Nevertheless, members of a value system can collaborate to improve their efficiency and to decrease their costs in order to accomplish a higher total margin to the benefit of all of them (e.g. by reducing stocks in a Just-In-Time system). A typical value chain analysis can be executeed in the following steps: ÂÂ · Analysis of own value chain which costs are related to every single activity ÂÂ · Analysis of customers value chains how does our product fit into their value chain ÂÂ · Identification of potential cost advantages in comparison with competitors ÂÂ · Identification of potential value added for the customer how can our product add value to the customers value chain (e.g. lower costs or higher performance) where does the customer see such potential. Conclusion Baxter Healthcare Corporation provides solutions to help other organisations to manage their changing accommodation requirements.

The Power of Fate in Macbeth Essay -- William Shakespeare

Fate is one person's destiny, it cannot be understood by mere mortals but a greater power beyond human comprehension. Fate is so powerful that it controls a person's outcome on life before it happens. Many people become victims of fate in which they catch a glimpse of what their future is going to look like, but do not totally grasp the outcome. Macbeth cannot fully comprehend the possible outcome of his fate because he is mortal, and therefore is a victim to his power driven quest and his ultimate fate. Many have been said to agree with this statement. For example, as stated in Shakespeare A to Z, "The Witches are an enactment of the irrational. The supernatural world if terrifying because it is beyond human control, and in the play it is therefore symbolic of the unpredictable force of human motivation." The magic of the witches is thus an image of human moral disruption. Through their own uncertain nature, they demonstrate- and promote- the disruption in the world of they play. The outcome of the first prophecy or encounter with the Witches is the beginning of Macbeth's downfall. After Macbeth was told about his potential reign as king, Macbeth said, "Stay, you imperfect speakers. Tell me more. By Sinel's death I know I am Thane-of Glamis. But how of Cawdor?...You owe this strange intelligence or why upon this blasted heath you stop our way with such a prophetic greeting. Speak, I charge you." (1.3.73.) After Macbeth tried to ask questions, the witches vanished. The witches seem to have watched Macbeth and studied how he is. They know his weaknesses are his greed and ambition, and by telling him this specific part of his destiny, his weaknesses will overcome his virtues. The witches then left Macbeth at this time possibly be... ...ant. As stated by Frank Kermode in the book Shakespeare for Students, ?Macbeth is a play about the eclipse of civility and manhood, the temporary triumph of evil, when it ends, virtue, and justice are restored.? ?Shakespeare displays a remarkable perception of the human condition by dramatizing not only the way in which evil enters Macbeth?s world, but also the devastating effect it has on those who yield to temptation and sin? (Shakespeare for Students page 238.) Macbeth is merely a victim of his fate. In this case, the weird sisters represent the wrath and cunningness of the various ways fate can play out. Fate has so much power that it can take over a person and leave them feeling almost possessed. If Macbeth were immortal and could understand his fate, he might have saved himself, but because he is mortal he is tricked, and subsequently, destroyed by fate.

Chartists and Chartism Essay -- European Europe History

Chartists and Chartism   Chartism was the name of a variety of protest movements in England during the 1830s and 40s, which aimed to bring about change   in social and economic conditions through political reform. Its name comes from the People’s Charter, a six-point petition presented to the House of Commons with the hope of having it made law. The six point included annual parliaments, universal manhood suffrage, abolition of the property qualification for members of the House of Commons, the secret ballot, equal electoral districts, and salaries for members of Parliament.   This was the first independent working-class movement in the world, that is, not simply sporadic uprisings or agitation, and arose after the Reform Bill of 1832 had failed. Working men had agitated for this bill and its failure left them still without the sought-for right to manhood suffrage. The Factory Act of 1832 had reduced working hours for children, but not for adults. The New Poor Law of 1834 caused resentment among workers by building workers’ housing in factory districts, where living conditions were bad.   By 1837 50,000 were out of work in Manchester alone, owing to overproduction, loss of trade, and the shutting-down of many mills.   Throughout the country, from 1839-1851 widespread depression was due to a combination of jobs lost, bad harvests, and high food prices. There were organized groups in London and Birmingham, but a national organization was inspired by Feargus O’Connor, who edited a Chartist paper, The Northern Star, and was   a rabble-rousing speaker.   The Chartists’ method was to circulate their petition throughout the country and gather signatures which were to be presented to the House of Commons at a giant convention in... ...nating the worst working conditions were gradually enacted into law.   Victorian England was to struggle with labor-management problems throughout the century. Gradually the working class would come to recognize its need for centralized organization and would gain support from radical middle-class intellectuals and writers, notably Henry Mayhew, who during the years 1849-51 investigated living and working conditions in London and published a series of violently-debated letters in the Morning Chronicle. It would appear that the efforts of the Chartists, while not immediately successful, served as valuable experience for a future labor   movement, as well as awakening the consciences of individuals and groups outside the working class.

Cooking Is Chemistry Essay

Cooking is chemistry. Everything is essentially chemical reactions. If you don’t mix the correct amount of grams of one element with another the product can result to be horrendous. The formula of sugar is C12H22O11. When you mix a certain amount of that into a solution of water with the addition of tea you a drink called sweet tea. Let’s say you mix add more C12H22O11 than water. Then your product will be syrup; a completely different mixture and ingredient. You went from a drink to syrup all because you added the incorrect amount of one compound. Now with the same molecules of sugar, let’s add heat, air and water. When you stir these ingredients with dry heat you get cotton candy. Wish is composed of nothing but carbohydrates and water. The added heat disperses the sugar and changes the state of the mixture from liquid to solid. Not enough heat will make it syrup and too much water will make it a drink. According to research, at any time you crack and fry an unfertilized egg, you reconstruct a protein called albumin. The proteins are held collectively by intermolecular forces such as hydrogen bonds & hydrophobic relations. Heat interrupts these forces & alters the color of the yolk from clear to white. If you add NaCl to water, it will raise the boiling point of water. It will take longer for the water to boil. Therefore, with salt, you can increase the boiling point of water 5 degrees. Another important concept of cooking is cleanliness. If the foods you eat are not properly handled and cooked, then you increase your chances of getting salmonella and other food related illnesses. If you heat you foods to proper temperatures you can eliminate the chances of bacteria’s and viruses being present. The DNA and structure of most viruses and bacteria are destroyed with heat, flame, water, salt, and other cooking elements. For instance, you may could a bloody burger but if you think, the cells and everything within the erythrocyte do not disappear. They are just simply destroyed and no longer living. The blood cells hop of the pan or fly away. Cooking is chemistry without chemistry; most of today’s food would not exist. If you don’t mix the right amount of grams of one element with another the product can result in being a different food . Chemistry allows foods to diverse, creating an ample amount of new ingredients and foods from different cultures. Everything is fundamentally chemical reactions!
