The challenges of managing communication, leadership and decision Essay

The challenges of managing communication, leadership and decision making - Essay Example The role of managers is to level possible disagreements and create positive climate and atmosphere. In hospitality, sector, cohesive groups, and self-managing teams create a tension and pressure which has a negative impact on critical analysis and decision-making process. The challenge of management is to restructure self-managing teams and introduce new methods and forms of communication between teams members. Cohesiveness is more likely when members of a team are to gather for a reasonable length of time, and changes occur only slowly. Strict guidelines and rules established by a manager will help to avoid conflict situations and turnover of members. Low morale and a negative attitude are often associated with a large number of team members undertaking similar work. This requires realistic planning by which the degree and quality of goal achievement can be determined. Teamwork coordination should be stated clearly and communicated to those concerned, and to those who are subject to the operation of the control system. Decision-making has a great influence on effective teamwork, because it involves some degree of participation. Team decision-making uses an overlapping form of structure (Dittmer 2001). Cross-cultural environment and cross-cultural teams create another challenge for management. This issue is typical for hospitality management and communication based on the nature of business itself. Hospitality management operates on the global scale and has to deal with different customer groups and culturally diverse employees. In this case, communication and leadership are the main tools used by management to eliminate cultural differences and tension (Beardwell et al 2001). There are always certain groups in any society that are discriminated against unfavorably due to the prejudices and preconceptions of the people with whom they have to deal. These preconceptions are sometimes verbalized, but often not, and the people holding these preconceptions may well be unaware of the way that they see and judge things and people. The key to managing a diverse workforce is increasing individual awareness of and sensitivity to differences of race, gender, social class, sexual orientation, physical ability, and age. The locus of change is the individual and change itself is both intra- and inter-personal. The action plan will can be based on employee' survey (questionnaire) aimed to identify the main areas of improvement and current problems faced by hospitality managers (Dow 1999). Primarily, it is crucial to develop mutual acceptance and membership within each team. Members in different departments and corporate office environment should have an initial mistrust of each other and a fear of inadequacies. If they remain defensive and limit their behavior through conformity and ritual, the manager should adopt diversity policies to reduce a negative impact (Bowen, Ford 2004). The priority is with questions of likes and dislikes, and power or dependency of group members. Critics admit that there is

Businesses in United States - Assignment Example Most mergers involve a bigger company absorbing a small enterprise, which has low market influence though mergers are not always full buying of the firm it depends on the terms of agreement. Moreover, firms, which merge operate dependently, and decisions made are together. Concisely, mergers are not always done out of good heart, but some firms absorb rival enterprises to reduce competition. On the other hand, there are companies, which operate solely without depending on other firms for support. Most mergers are ill intended since the bigger firms use acquisition as a way of extinguishing firms, which pose a threat to their customer base. Businesses go internationally in order to get raw materials, as well as access a ready market. This is experienced in countries where the market is flooded, therefore; international markets have cheap labor and readily available raw materials. International corporations enjoy protection from parent countries incase their operations are threatened b y rival firms and government regulations in the foreign country. International mergers Chase bank is a national bank, which has branches both nationally and internationally. Chase bank first started as Chase National bank before it merged in nineteen thirty with Equitable Trust Company of New York and Interstate trust Company. During initial times, Chase National bank was a managed by JPMorgan Chase & Co. Subsequently in nineteen fifty five, Bank of the Manhattan Company merged with Chase bank to form a giant corporation, which established branches in more than sixty countries in the world. Chase bank is among top four banks operating in United States economy. All the shareholders and management of the two banks, however, universally accepted the merging. There was 50% management of the business since the two firms joined their names and formed Chase Manhattan bank, which became a prominent bank in the world (Gaughan 2005). Chase Manhattan Bank, however, abandoned their logos and de signed a new logo octagon in shape representing pipes laid down by Manhattan Company. The logo was more of favoring previous activities of Manhattan than Chase bank. Reasons for merging Chase National Bank and Manhattan Bank merged so that they can increase their financial performance. Merging increases the capital available in the firm therefore, high sells revenue and net profit. Furthermore, acquisitions reduce costs spent by the banks in the operations. Cost is a factor, which makes many firms experience loses. More so, bank mergers lead to increase in market size. Geographical diversification is a factor, which guides many firms to merge. Chase National Bank was in New York while Bank of Manhattan is located in Manhattan, which is located in different states. Entities that start new in a different geographical area takes lots of time to get market acceptance therefore, to curb this, most firms acquire entities in the same geographical area and operates with them. Most enterpris es use the company’s names to decrease on risks and accrue long run profits. Riegle-Neale Act of 1 June (1997) allowed banks to expand geographically and acquire new markets throughout the United States and internationally. Stewart’s merger motivation theory argues that enterprises merge to reduce on debt capacity, which other banks owe them. Businesses, which have high debts that they cannot settle, agree to mingle with a firm operating well to help in settling of the accumulated debts. As Chase bank merged with Manhattan bank, their capital base increased as well as the lending capacity. This reduced dependency levels and businesses were self- reliant. Normally in businesses,

Assignment Essay Essay Sustainable tourism is being able to the deliver positive environmental, social, and economical results with thought to the needs of the visitors, host community and surroundings. Sustainability as defined in the Brundtland commission report it states as â€Å"meeting the needs of the present without compromising the needs of the future generations to meet their needs†. For example, the small business are starting to practices sustainability principles by changing to renewable energy sources, reducing use of paper and recycling more. As a result, the concept of sustainability addresses the aspects of â€Å"triple bottom line† meaning the balance of societies, economy and the environment are described by (Bonevac, 2010). According to the World Tourism Organization, â€Å"sustainable tourism means meeting the needs of the present tourist and host regions while protecting and enhancing the opportunity for the future†. Instead of just being a product, sustainable tourism is a philosophy that underpins all tourism actions (Owens, Is there a Meaningful Definition of Sustainability? , 2003). To all tourism development and management, it is a fundamental concept instead of being an add-on factor. The foremost aim of sustainable tourism is to maintain the economic and social return of tourism development while reducing or justifying the unattractive impacts on the natural, historic, cultural or social environment (Governemnt, 2009). The stated objectives attained by matching the needs of tourists with those of the destination. Sustainable tourism is an industry, which challenges to make a little impact on the environment and the local culture, though helping to produce income, employment and the preservation of local ecology. Hence, responsible tourism is both cost-effectively and culturally responsive, meaning have minimum impact on the environment and culture of the host community (Group, 2007). Scotland Tourism Organization has defined sustainable tourism as â€Å"tourism committed to generating a low impact on the surrounding environment and community by acting responsibly while generating income and employment for the local economy and aiding social cohesion† (Organisation v. s. , 2013). Scotland Sustainable tourism aspires to guarantee that economic development in terms of encouraging experience for each one involved local community, Tourism Companies and visitors. In practice, sustainable tourism means greener transport, given that transport is innermost to tourism; however it also put pressure on our natural resources and contributes to our worldwide environment impacts. Procedures like cheering visitors to utilize communal transport, and advance in cleaner forms of transport will assist in this area (Organisation v. . , 2013). Regular and environmental strains a more even stretch of visitors lessens pressures on the natural and built environment and on communities, and capitalizes on the financial payback. Scotland Tourism Organization modifies its advertising drive to persuade a stretch of visitors throughout the year and around state (Organisation v. s. , 2013). For example, â€Å"surprise yourself†. There is necessary to work with the public, private and independent sectors to determine the environmental and social impacts of tourism. These guarantees that tourism expansion carries a encouraging experience for home people, tourism companies and the tourist themselves (Organisation v. s. , 2013). Green accommodation is one in that all room offers lessens their misuse, energy and water use. The green Tourism Business Scheme persuades businesses to trim down their environmental impacts. The scheme is one of the largest of its land in Europe with over 800 Scottish members (Organisation v. s. , 2013). However, any tourism industry can take advantage from flattering more sustainable through safeguarding the very features on which tourism depends; taking a sustainable move to tourism expansion is the only way to guarantee long-term tourism expansion in the South Pacific (Organisation v. s. , 2013). The success of tourism in any country depends on taking care of the environmental or social impacts of tourism development. The visitors benefit from sustainable move to tourism throughout from enhanced relates with local communities, a tall value tourism experiences and a natural and fabricated environment. Thus, by fetching a sustainable tourism destination will provide the South Pacific Tourism Businesses a cutthroat frame by producing community assistance for tourism; attaining value savings and designing innovative marketing prospect. As the tourism industry develop in as many regions and countries, it generates noteworthy impact on the consumption pattern, natural resources, pollution and social systems (Organisation v. s. , 2013). For the industry to survive as a whole it is vital to understand and interpret the need sustainable and responsible planning and management. To begin with, education and collaborative partnership are approaches that can assist destinations attain more sustainable tourism. The whole idea of sustainability based on the association through environmental, ecologically and socially responsible tourism. Partnerships with local communities through rural community gathering before and during development are needed in order to let alone the frequent divergence between conservation initiatives and traditional resources users (Billington, Carter, Kayamba, 2008). The departments from the government can collaborate with the resource owners to develops and negotiate over the investment on proposal (English National Park Authorities Association, 2009). For example, the Chumbe Island Coral Park is a good example of collaborate partnership, which was developed to sustain the natural beauty and attractions of the island (English National Park Authorities Association, 2009). Chumbe Island is located in the Indian Ocean channel of the coast of the semi autonomous region of Zanzibar (English National Park Authorities Association, 2009). The person responsible for the project on the natural park at Chumbe Island was (David, 2011). During her work life, (David, 2011) experience the need for the conservation and sustaining of the natural flora and fauna. (David, 2011) developed an innovative approach to protect marine conservation combined with tourism development through the sustainable and multilevel partnership approach to promote successful marine park management, awareness of marine conservation and sustainable tourism management. David, 2011) Develop a small marine park that would help consume a unspoiled coral reef, offer environmental education for both the locals and the foreign visitors and generate management fund through authentic ecotourism. Thus, the need for the park at Chumbe Island arose due to improper aid and the government in the country noted conservation programs. Hence, the collaborative partnership arose to sustain the nature conservation of Tanzania for the future (English National Park Authori ties Association, 2009). Secondly, the partnership approach deals with the local communities because they are the essential people who are the resource owners (Governemnt, 2009). Engaging the local community in the environmental education on sustainability through workshops and seminars will increase their concerns for the global issues such as climate change (Clark, 2013). In addition, collaboration with NGO has to hold workshops with the angler’s, to engage them in sustainable fishing practices and conservation of the resources (David, 2011). Thus, the young and the old generation in the area is to be informed about sustainable fishing practices, laws and regulation regarding fishing practices and marine conservation area and the benefits of marine protected areas (Ki-Hoon Ball, 2003). All this environmental awareness, education and training initiative with the community are to provide skill development on sustainable tourism (Group, 2007). The scale of growth of the tourism industry In the South Pacific is rapidly and that the environmental and social, economic impacts of it cannot be overlooked (Azam Sarker, 2011). This has caused the Pacific Region to find ways in which the industries could be made more sustainable. The industry is more sustainable through minimizing resource use and waste production (Othman, 2004). For the sustainability of tourism, water is the major issue for concern. For example, a tourist in a hotels uses on standard one third of more water per day than a local inhabitant uses and put severe restriction on local supply (Othman, 2004). Activities such as golf course, artificial snow ski’ resorts are in demand of water. For small and medium sized business, sustainability thought of an expensive and difficult idea (Billington, Carter, Kayamba, 2008). Most of the dominating tourism industries in the South Pacific have not actively engaged in government activities that encourages that adoption of sustainability practices (David, 2011). There are a number of barriers identified by the researchers that hinds implementing sustainability practices in South Pacific tourism businesses including the financial crisis for implementation, the labor insecurity of being certified, lack of government and industry support the technical nature of information forums. Hence are a number of actions businesses could undertake to improve environmental performance (Azam Sarker, 2011). Activities’ relating to efficient resources use and waste management includes minimizing energy consumption, for example using open ventilation instead of air-conditioning and heaters encouraging the use of renewable sources and improved technology also Getting involved in accreditation programs (Owens, Is there a Meaningful Definition of Sustainability? 2003). There is a need to promote and facilitate the reduction, reuse and recycling of materials and water quality including the efficient treatment of sewerage, avoiding discharge into marine and rivers (Organisation, 2005). For example, in Australia the Australian formula 1 ING grand Prix Corporation, which works with environmental packaging and waste recycling partner to minimize the impact of the race on the environment? Billington, Carter, Kayamba, 2008) Thus, by minimizing waste use, energy use and waste production, businesses can reduce their impact on the environment and achieve cost savings (Ki-Hoon Ball, 2003). Furthermore, the conserving and giving value to natural and cultural heritage is of critical importance’s, in order to enhance the quality of life of local communities through tourism, and connect the people in is scheduling and management (Organisation, 2005). The growing awareness’s and generating direct and indirect support for conservation is the key role played by the tourism industry (Group, 2007). The generation of economic propensity for the tourism industry is to provide with quality natural and cultural heritage (Azam Sarker, 2011). This would ensure the long-term competitiveness, viability and the prosperity of tourism enterprises and destinations and the quality of life of local communities and to the visitor experience by providing a safe, satisfying and fulfilling experience to the visitors available to all without discrimination by gender, race, religion, disability or in other ways (Organisation, 2005). Areas that are of importance to tourism natural and cultural includes the natural landscapes quality and variety, man-made cultural landscapes, heritage and historic sites, the flora and fauna diversity, local uniqueness such as art, crafts, cuisine, language events and festivals (Organisation, 2005). Thus, to address these issues listed above relevant action like being more prepared to use the tourism argument as to fund the prevention of nature and culture and to prevent damaging change (Clark, 2013). Also strengthening the relationship between protected area and local tourism interest, within the context of a sustainable tourism strategy and action plan would lead the South Pacific to be more sustainable (Organisation v. s. , 2013). Sustainable development is holistic in nature; therefore, it requires management of policies and coordination of action between sectors (Othman, 2004). To control the impact of tourism initiated by environmental or developmental strategies and policies legislation and regulations are necessary (Governemnt, 2009). Appropriate strategies or sets of policies for specific aspects of tourism were developed. For example, in Bulgaria the separate strategy for ecotourism, which reflects the sustainability principles? (Bonevac, 2010) This initiative can also be taken by the local Ministry of Environment of Tourism to integrate the strategy in terms of regulations (David, 2011). In coordinating and ensuring success of this specific sub-sector, such regulations and legislations can be very helpful. This can be very helpful in demonstrating processes and formulating policies that could be modified more widely in tourism (Ki-Hoon Ball, 2003). Strategy and policies must be developed and implemented at both local and national level in order to achieve effective result. Most countries in the South Pacific are in the process of decentralizing their political and administrative structures so local decision-making is the vital aspect toward sustainability development (English National Park Authorities Association, 2009). An integrated approach to the development and management of tourism is within local destinations, is recognized as the most successful direction to sustainable tourism (Governemnt, 2009). Thus, it is vital for the national and local strategies to be corresponding but these two variable in tourism strategies vary in terms of national tourism strategies relates to the national tourism vision of the overall position and direction (Organisation v. s. , 2013). While local tourism strategies relates to the holistic of the local destinations in areas such as local objectives and priorities, local resource opportunity and constraints and many more (David, 2011). Hence, the identifying of policies and instruments to create the enabling environment for sustainable tourism is more of national strategy while the determining of what happens on ground is more of local strategies (Governemnt, 2009). Both the national and local tourism strategies are required for sustainable tourism to embrace the principles of sustainable development and both strategies are reliable and commonly reinforcing (Othman, 2004). Finally, the command control instrument allows government to exert strict control over certain aspects of development and operation, backed by legislation (Organisation, 2005). Legislation, regulation and licensing are the interdependent tools that can be used to strengthen sustainability by setting out requirements that are compulsory and enforceable and which lead to sanctions and penalties if they not met (Billington, Carter, Kayamba, 2008). The process of checking and signaling compliance with regulations or otherwise identified obligatory standards; assigning permission to operate is called licensing (Organisation, 2005). To control aspects of business development and operations and to influence people’s behavior government are in a position to apply laws, regulations and penalties. These legislation and regulations must be applied when the governments believes that it is necessary to do so (Governemnt, 2009). Thus, for regulations to be successful, it has to be relevant, clear, practicable in terms of compliance and capable of being enforced. In order the tourism industry to be more sustainable the laws and legislations should enable and support the sustainability of tourism and give authority to act (Billington, Carter, Kayamba, 2008). It should also seek to raise sustainability performance above such standards through other means, which would also stimulate personal commitment towards continual improvement. For example, in the government of Fiji builds up a (EIA) environmental Impact Assessment regulation, which stated that for any company or hotel with an EIA reports in Fiji, has to provide the Fiji Government with an EIA report of the development to progress (Turnbull, 2003). There are a number of areas in which laws and regulations can be implemented to attain more sustainable tourism industry and that includes operation, management and development which are controlled by this legislation to protect the environment, communities, culture and heritage, visitor experience and the business as a whole (Turnbull, 2003). The purpose of government intervention in the sector as law provides a vehicle for underpinning sustainability. These legislations can also provide the basis for enabling the control and licensing of activities specific to the tourism sector and for the undertaking to certain action to support tourism development (Organisation v. s. , 2013). To conclude, sustainable tourism is all about forecasting of long-term, working together examining on results and adaptive to change and the most effective thing is communication to put across the message of sustainable tourism. It is the duty of the private, public and independent sector to acquire leadership role in tackle the challenge of this sector. The degree at which the tourism industry is increasing in the South Pacific forecasts that the environmental and social impacts of tourism cannot be disregarded. Traditionally, a number of sustainable tourism activities has been carried out and is supported by the national Tourism Organization of the South Pacific countries. However, there are a number of challenges that still stay alive and need attention in order to be more sustainable tourism industry, like climate change. In order to tackle these challenges and grip future sustainable opportunities in a harmonized manner, research and development done in these South Pacific countries to handle these issues through sustainable tourism strategy plan. The tourism strategies plans would assist the tourism industry to change unenthusiastic community discernment of the industry and achieve economic benefits through sustainable practices. It believed that it would egg on business to hold sustainable tourism practices in order to meet consumers demand and to improve business performance. Sustainable tourism should be broadcasted and celebrated amongst tourists, host communities and the participants in the industry move the industry toward sustainability. Nevertheless, the commitment to change and improve must be authentic and supported on well-established procedures and actions that is to be achieved.

A control sample should be a constant variable that was not exposed to the factors being tested in the experiment. In this case, the purpose of the lab was to determine the presence of starch, lipid, protein, and sugar in various solutions. Distilled water did not contain any of these experimental factors and therefore it acted as a control sample. The distilled water played a very important role in this experiment considering that the results of the experimental samples must be compared to the control in order to form a conclusion (Rodriguez, 2013). By comparing the results of the control, the colour changes which had occurred in the experimental samples could be identified. If there was no control, one wouldn’t have been able to determine any valid changes in the experimental results since there was nothing to compare them to in order to verify the changes. In this experiment, distilled water was used a s the control instead of tap water because of the absence of metals and minerals such as iron and calcium. These elements have the potential to alter the results of the experiment by creating unwanted reactions with other substances in the experiment. Therefore, in order to have an accurate control to act as a reference source for the results of the experimental samples, distilled water was used (Myers, 2013). The Iodine solution was commonly used to test for the presence of starch in a substance. During the presence of starch, the Iodine solution would turn into a dark blue/black colour. The colour change was caused by the chemical reaction between the starch and the iodine. Amylose was a polysaccharide consisting of glucose units; it was a type of starch, in fact starch was made up of a mixture of amylose and amylopectin. Therefore in this experiment, when the iodine solution was added into the Amylose solution, the resulting solution had a deep bluish-black colour. The helix structure of amylose resembled a coiled spring. The element iodine, a non-polar molecule, on its own was insoluble in water; hence it was dissolved in an aqueous potassium iodide solution forming potassium triiodide which was soluble in water. The linear triiodide ion (I3-) basically slipped inside the coil of the amylose molecule resulting in an extremely blue/black colour. The transfer of charged particles (electr ons) which occurred between the amylose and the iodide ion altered the spaces between the energy levels/electron orbitals. This meant that light was absorbed by the solution at a different wavelength resulting in the colour change. The presence of starch was also determined in the unknown X and unknown Y solutions. The unknown X solution had a less intense shade of blue indicating that there was a lower concentration of starch in that substance (Iodine test for, 2012). Benedict’s solution was a clear blue liquid containing copper sulfate used to test for the presence of simple carbohydrates such as allmonosaccharides and several disaccharides like maltose. The presence of these sugars such as glucose triggered a chemical reaction between the sugar and copper sulfate (after heating which provides the energy required to initiate the reaction) resulting in a reddish-brown precipitate if there was a high concentration of sugar (2% or more). The solution could also turn greenish, yellow, or orange with lower concentrations of sugar. During this experiment, the glucose solution changed into a dark orange-red colour, while unknown X turned into a light yellow/beige colour, the unknown Y with a lime green colour and the maltose resulted in a yellowish-green colour. This suggested that the sugar content in maltose, unknown X and Y was low (less than 2%) compared to glucose (Benedicts reagent, 2014). Specifically, the Benedict’s solution tested for reducing sugars which consisted of an aldehyde group (presence of the CHO group). In the presence of reducing sugars, the copper (II) ions were reduced to copper (I) ions forming copper (I) oxide, a reddish-brown precipitate that was insoluble in water. In this experiment, the glucose possessed accessible electrons for donation, which the blue copper (II) ions were willing to receiving/accept to become reduced to reddish copper (II) ions. When the glucose donated an electron, it became oxidized while the copper (II) was reduced. For this reason, glucose was considered to be a reducing sugar capable of initiating a chemical reaction with the copper sulfate in Benedict’s solution. Similarly, maltose, a reducing disaccharide, reacted with the benedict’s solution when heated to form a murky yellow precipitate. Maltose molecules have a linear open-chain structure which made them accessible to react with the copper sulfa te in Benedict’s solution resulting in a dark yellowish colour indicating a low concentration of sugar (Yool, 2014). However, sucrose, also a disaccharide, did not provide a positive test for sugar. This was because sucrose was not a reducing sugar. The bond between the two sugars which made up sucrose, fructose and glucose, was formed in a particular way which inhibited the sucrose to isomerize to aldehyde form causing it to be a non-reducing sugar. The molecular structure of sucrose was not linear meaning that it was incapable of opening; it was basically stuck in its cyclical form. This prevented the sucrose from donating electrons and reducing the copper (II) in Benedict’s solution resulting in no chemical reaction, colour change, or formation of precipitate (Benedicts reagent, 2014). Biuret’s reagent was used to test for the presence of protein. The chemical reaction which occurred in the presence of protein resulted in a violet colour solution due to the peptide bonds which made up protein. The biuret reagent contained hydrated copper sulfate; the copper (II) ions formed coordination complexes as the single electron pairs of the four nitrogen atoms in peptide bonds surrounded a central atom which was the copper (II) ion. As the metal complex was formed, the wavelength at which light was absorbed changed to violet from clear blue indicating the presence of protein. Additionally, the greater the amount the protein in a solution, the more intense the colour change considering that there were more peptide bonds present resulting in long chain peptides (Biuret test, 2014). Sudan III was a red reagent that detected the presence of lipids. This solution was insoluble in water, however would dissolve in lipids. It would stain the present lipid an orange-red colour. In this experiment, only the unknown Y solution presented a distinctive orangey colour on top of a yellow solution after the addition of the Sudan III reagent suggesting the presence of lipid in this unknown solution. This showed a clear separation of the lipid and water portions of the solution considering that the two did not mix; lipid molecules were nonpolar while water molecules were polar. For this reason, the staining had only occurred at the top layer of the solution (Sudan iii, 2014). Carbohydrates were essential nutrients to leading a healthy diet. They were important energy source for the human body. However, they were not used straightaway due to excess intake; the body would store the carbohydrates in the form of glycogen in the muscles and liver. The body used the glycogen stored in the muscles while the brain obtained energy from the glycogen stored in the liver which could only support a limited amount. Therefore, upon excess consumption of carbohydrates, the carbohydrates would be converted into fat which was stored in the fatty tissues. This would also simultaneously increase the glucose levels in blood which triggered the release of insulin in order to maintain homeostasis. Insulin was a hormone secreted by the pancreas into the bloodstream with the purpose of lowering the sugar levels. A great quantity of insulin not only triggered the body to store the extra carbohydrates as fat but also inhibited the release of the stored fat. This meant that the stor ed fat lost its ability to be used as energy. Additionally, high levels of insulin restrained the secretion of glucagon and growth hormones. Glucagon was a hormone secreted in the pancreas that initiated the breakdown of fat and sugar to increase the blood sugar levels. Growth hormone was responsible for muscle development. Lastly, the excess intake of carbohydrates which increased the blood glucose levels caused the secretion of extra insulin in order to lower the sugar level at a rapid rate. This caused hunger considering that after a short amount of time; the body’s blood sugar levels would be lower than normal causing the hungry sensation to convince the body to consume more carbohydrates increase the sugar levels (The relationship between, 2008). Cholesterol was a waxy, sterol, substance found in most body tissue such as in bloodstream and the nerves. This compound was produced by the liver in the human body and circulated through one’s blood stream. Cholesterol could also be found in one’s diet; foods with a great amount of saturated and trans fat such as meat and dairy products contained this substance. The presence of high level of cholesterol in the body greatly increased the risk of many heart diseases such as heart attacks and strokes. This was because when there was an excess amount of cholesterol in the blood, it could accumulate in the interior walls of arteries which provided various parts of the body the nutrients and oxygen needed to function properly. Plaque was formed as the extra cholesterol and other substances such as fat and calcium stuck to the inner walls of the blood vessel. This sticky substance would harden and decrease the circumferences and flexibility/elasticity of arteries. This health issue was known as atherosclerosis; the clotting of blood vessels due to the buildup of plaque limiting the flow of blood to several parts of the body such as the brain, the heart, and other organs. Depending on which of the many arteries in the body was blocked, there were several potential heart diseases. If the plaques clot the coronary arteries which supplied the heart with oxygen-rich blood, heart attacks may occur and if there was a blockage in the carotid arteries which fed blood to the brain, the reduced blood flow to the brain may cause a stroke. Most of these heart diseases were serious and even deadly (What is atherosclerosis?, 2011). Protein could be used as an energy source for the human body; however not the most efficient method. As protein was digested by the body, it was chemically broken down into amino acid subunits. Glucose and amino acids were chemically alike with the exception of the presence of nitrogen atoms in amino acids. In the absence of nitrogen, the amino acids could be converted into glucose or fatty acids which provided energy for the body. Due to the additional steps of removing the nitrogen, proteins were a slower source of energy, but longer lasting compared to carbohydrates and lipids. Furthermore, the use of protein as an energy source could be harmful to the body due to the by-products formed from the breakdown of amino acids. The nitrogen atoms contained in all amino acids were converted into ammonia during amino acid catabolism. The substance ammonia was toxic as it accumulated in the blood causing the body to excrete it through urination. However, high levels of ammonia would damage the liver and the kidneys. Also, the presence of a large quantity of this compound was poisonous to the cells in the body (Cloe, 2012). Errors: During this experimental, a few errors had occurred. The test tubes filled with the experimental samples were not washed properly for the next nutrient test. This resulted in absurd colour changes. At times, not enough indicator solution was added to the samples. This might have affected the resulting colours. Lastly, during the test for sugars, after the addition of the benedict’s solution into the samples, the solutions were not heated evenly for the same length of time. A few samples did not obtain enough energy for a potential chemical reaction/ colour change to occur. Conclusion: It was concluded that distilled water functioned as the control in the experiment due to the absence of metals and minerals in the liquid which could possibility initiate unwanted reactions. The control was used to provide a reference source for the obtained results from the experimental samples in order for the changes to be valid. The iodine solution was used to test for the presence of starch. The chemical reaction between the triiodine ions and starch molecules triggered the colour change of the solution to deep blue/black. Starch was detected in the amylose, unknown X and Y solutions. The benedict’s solution was used to determine the presence of reducing sugars. The chemical reaction between the copper sulfate in the benedict’s solution and the sugar molecules triggered a colour change in the samples. The sugar molecules reduced the copper (II) into copper (I) resulting in a reddish precipitate. With a lower concentration of sugar molecules, the samples turned gree nish, yellowish or orangey. The presence of sugar was determined in maltose, glucose, unknown X and Y samples in this experiment. Biuret’s reagent tested for the presence of protein. The copper sulfate in the reagent formed metal complexes with the nitrogen atoms found in the peptide bonds of protein. This resulted in a colour change of the samples to violet if protein was detected. The Sudan III solution tested for the presence of lipid. Since the solution was insoluble in water and soluble in lipids, the colour change to orangey red was only found on the top layer of a few samples. The presence of lipid was determined in the unknown Y sample. Furthermore, excess intake of carbohydrate increased the sugar level in blood. This triggered the release of the hormone, insulin, with the intention of lowering the sugar level to maintain internal balance. The release of this hormone by the pancreas caused the extra carbohydrates to be stored as fat. Also, the presence of a large amount of insulin caused the frequent sensation of hunger. This was because the insulin quickly lowered the sugar levels causing the body to want more carbohydrates to increase the sugar levels to maintain homeostasis. High levels of cholesterol in the blood resulted in the accumulation of plaque reducing the blood flow to various part of the body. This was a major risk factor of heart diseases such as heart attacks and strokes. Lastly, when the body used protein as an energy source, there would be an elevated level of ammonia in the body considering that it was a by-product of the breakdown of amino acids. The high level of this toxic compound would cause harm to the kidneys, the liver and other body cells. References: Benedicts reagent. (2014).

Importance of Setting in Eveline of James Joyces Dubliners :: Dubliners Essays

Eveline: The Importance of Setting Setting is one of the most significant elements in a story. The setting goes far beyond the simple physical attributes and external face value. It seems "Eveline" solely takes place in Dublin in an old room, but the setting actually plays a key role in the story. The setting in "Eveline" helps the reader to better understand the behavior of the main character. The setting in "Eveline" is paralyzing, and this helps the reader to understand why Eveline does not go with Frank to Buenos Aires. In the majority of the story Eveline "sat at the window," (512) which parallels with her paralysis because she does not move. Eveline "was going to go away like the others" (512) because she was one of the only people left in Dublin from her childhood. However, Eveline doesn't go since she is trapped in her setting. Almost nothing in Eveline's setting ever changes throughout her life. The significance of Eveline looking around the room "reviewing all its familiar objects" (512) is that she "never dreamed of being divided" from them. All around her Eveline "had those she had know all her life about her" (512). Eveline is a product of her environment. The reader can see how the setting never changes, Eveline's life molds to it. This explains the reason for her not going away and starting a much happier life. It is extremely hard for her to make the decision of whether or not to go with Frank because she only knows one way. Eveline understands that she has "a hard life,"(513) and she has the chance to go to a place where "it would not be like that" (513). However, it scares Eveline to change her setting. After thinking about leaving she did not find her present setting as "wholly undesirable" (513) as she previously did. The latter part of "Eveline" is set by the sea. This sea is a symbol of rejuvenation for Eveline. Much like in "The Awakening" by Kate Chopin, the sea is a way to escape life. "All the seas of the world tumble around her heart," (515) and Eveline is unable to flee from her life to go away with Frank. Eveline's mind has been subconsciencly designed by her environment, and she can't imagine living life any other way. Eveline is so confused and doesn't know what is holding her back, but something is.

Sins Ability to Control a Person in The Scarlet Letter :: essays research papers

Sin's Ability to Control a Person Sin is a major theme in The Scarlet Letter, by Nathaniel Hawthorne. In The Scarlet Letter, sin is practiced throughout a few of the characters. The only difference amongst them is the way that they try to atone for it or be completely enveloped by it. Sin can take control of a person and devour them completely to the point of no return. Hester at first felt that her sin had taken away everything that she had and left her with only one thing, Pearl. When she first walked out of the prison and onto the scaffold, she was full of pride but from that point on, she was isolated from her community and forced to live in the forest with only her baby. Hester felt that suicide was the only thing she deserved after committing adultery. She says, "I have thought of death, have wished for it?would even have prayed for it, were it fit that such as I should pray for anything. Yet, if death be in this cup, I bid thee think again, ere thou beholdest me quaff it. See! it is even now at my lips." As time passes by, Hester?s personality gradually changes and she becomes a completely different person. She has become more caring although her lifestyle became worse. As for Reverend Dimmesdale, he is completely enveloped by his guilt from the sin that he has committed and is unable to come forward to confess it. Instead, he tortures himself each and every day. Hawthorne writes, ?His [Dimmesdale?s] inward trouble drove him to practices more in accordance with the old, corrupted faith of Rome than with the better light of the church ? In Mr. Dimmesdale's secret closet, under lock and key, there was a bloody scourge.? Later, he says that he tries to confess by saying that he has sinned but the Puritan community misinterprets it as a sign of him being a saint and that if he has sinned then what are they. Chillingworth is also a sinner because he pretends to be a physician when he really isn?t and takes that role to torture Reverend Dimmesdale. Chillingworth tortures Dimmesdale slowly by hurting him both physically and mentally. During this time he pretends to take care of him in which he really isn?t. Hawthorne writes, ?Calm, gentle, passionless, as he appeared, there was ? a quiet depth of malice ? but active now, in this unfortunate old man ? imagine a more intimate revenge ? upon an enemy.
