Appearance vs. Reality in Twelfth Night Essay

Theme of Appearance vs Reality is pervasive throughout the play and its various facets are manifested through various thematic expressions. At the very start of the play, the most subtle aspect of Appreance vs Reality is presented in the form of Orsino’s conviction of love for Olivia. He becomes a victim to fictitious idealism as he has not seen Olivia and does not have a glance in three months (the course of the play). Shakespeare depicts Orsino as a sentimental lover who suffers from the ‘sweet pangs’ (II.4.16) of love and ecstasy that have no real existence. Instead of locating the reality of his passion and to find a remedy, he again goes for a solution that is deceptive. In the first two scene of the first Act, he yearns for music to cure his sentimentality. Undoubtedly Orsino has reverted himself into the realm of illusory world by the caprices of his imagination. Shakespeare has juxtaposed the Duke’s unadulterated distress for Cesario’s ‘sister’ with Orsino’s fictitious idealism. He implies that behind all the fake sentimentalities of affectation there is a genuine individual who has genuine concerns. But revelation of another deception i.e. unearthing that Cesario is a woman, helps him to cast away his own belief in appearance and he acknowledges the speciousness of his apparent made-up fondness for Olivia. Orsino does not fell a prey to appearance (instead of reality) due to any inherent flaw in his personality or his psychological complexities but it is a result of his lack of suffiecient experience in the real world especially in the amorous affairs. Same is the case with Olivia whi looks for apprence instead of locating the reality o his passions for Orsino. But Shakespeare juxtaposes them with certain other minor characters like Molvolio who do not acknowledge the reality and never cast away their belief in appearance till the end of the play whereas Orsine and Olivia learns that appearance is always deceptive and becomes realist at the end of the play..

Misuse of Plastic Essay

Human being plays a key role in environment as he has a capable mind and will power to do everything by the skill and technology he has developed so far. But most of his activities done for his development and welfare have been causing seriously negative impacts on the virgin environment he has been blessed with. We can prepare a long list of human activities that have been disturbing, destabilising and degrading the natural environment. The explosion of human population has enhanced the negative impacts of human activities on environment. Man has adopted such a life style which has no room for conservation and preservation of environment as he has become just a consumer in the modern world. He has destroyed many terrestrial and aquatic habitats causing numerous species of plants and animals to go extinct.

Bali Versus America

The number of various cultures spanning the globe is immense. Cultures are influenced and driven by a unique language and style all their own. The land of Bali and America are separated by thousands of miles and have contrasting differences in what is viewed as acceptable behaviors and mannerisms. Language barriers can form walls of separation between what is culturally acceptable in these two countries. These cultures develop influential ways of living that are firmly rooted in tradition.I will discuss the different attitudes and in-born beliefs surrounding the subject of politeness as well as the issue of confrontational behaviors. The way people communicate goes beyond the different languages spoken in America and Bali. . For example, an American woman with mixed decent of Italian and Jewish/Hungarian was raised in the hustle and bustle of New York City. If we placed her in Bali, she would be viewed as an outcast. It’s her New-York-Minute attitude where she needs to be verb ose and outspoken to get her point across and get what she wants, both in the workplace and in her leisure.Some Americans might be taken aback by her husky attitude and view it her in-your-face attitude as insulting and rude. Other people, however, would simply see her as another American trying to make her place in society. The discussions surrounding polite behaviors in America take on differing viewpoints in Comparison to the people of Bali. Americans can be very intense and, according to people of Bali, they would be seen as insulting and out-of-control. It’s the American demeanor and body language that is also so different from the Bali culture.It is also common knowledge among certain Jewish families in America to expect an individual to stand up for her rights and be willing to object to views that oppose her Jewish way of life. Many Americans are expected to be confrontational and argumentative. This is not a choice, but instead a way of life for many Americans and a cultural expectation. Then, if we venture to the beautiful landscapes of Bali, we find a much more complacent society. In fact, emotional arguments are almost never even heard of in Bali. The people of Bali are very kind, soft-spoken and set in their way of showing great respect to one another.A linguist living in Bali for numerous years can attest to this. Try to take the pleasant, soft-spoken cultural demeanor back to New York City and a lovely Balinese traveler might discover that the congested, faced-paced whirlwind known as New York is too loud and offensive—even instilling a sense of fear in an individual. A person will discover, dependent on how deeply-rooted they are in their cultural origin, be it in America or Bali, that they must adapt if they want to survive and succeed in a society with such stark contrasts to one’s homeland.Regardless of the language barriers found in dialogue, contrast is furthered and muddled-over by the cultural influences that are sew n into family tradition. From the same token, many Americans—New Yorkers included—can also feel the fear-factor begin to kindle unpleasant feelings if they are immersed in a soft-spoken culture such as Bali. The people of Bali would be very apprehensive—even shocked—by how American treat one another. The people of Bali view politeness and respect very highly. Bali people would wonder how Americans can function by the way they are so rude and offensive to one another.Par to this apprehension stems from a combination of cultural-language elements: for one, the attitude surrounding confrontation and arguments in America and Bali are so different that they would cause great problems if an American were to move to Bali and vice-versa. Then, when this duress—regardless of how small it might be—is compounded with foreign cultural influence, a resulting sense of fear is likely to occur. The Bali people would be the ones who are fearful of the Americ an’s aggressiveness.If an American were to move to Bali, she would also be culturally shell-shocked but from a different perspective. The Bali people would not react to the American’s rudeness and lack of sensitivity. Thereby making it nearly impossible for an American to succeed in this country American cultures and Bali cultures find argument to be influential, but with contrasting expectations. Life is meant to be interesting and filled with excitement. It’s a means of opening up and sharing one’s personal beliefs that are paramount to success in this culture.Americans are brought up in a society that almost requires aggressiveness. Sometimes this aggressiveness does not consider being polite. It is ignored, at least according to the people of Bali. Bali people, in fact, might deem this behavior as rude and self-serving. This, in turn, can put people on the defensive, sensing the needed to act guarded or cautious when immersed in American cultural beli efs. In closing, it is apparent that the various cultures differences surrounding polite mannerisms and confrontation in the work place and on the home front are starkly different.It’s a different ways of experiencing life. The language barriers are but one challenge that people face if they choose to live or work in a country other than the one they were raised in. As this world becomes more and more global, on both business and family fronts, it’s easy to see that a person doesn’t have to travel out of her own country to experience another culture. The stark contrast of cultural influence is but another step toward uniting this planet as we seek ways to work and live together, harmoniously.

Land Law Essay Example | Topics and Well Written Essays - 2000 words - 3

Land Law - Essay Example One such attempt is the Land Registration Act 2002 which was seen as the successor of the Land Registration Act 1925 (Francis, 2013).1 The land registration Act of 2002 was based on the earlier UK land laws such as the land registration Act of 1925. Although the Land Registration Act 2002 meant to improve on the issues of the Land Registration Act 1925, it still has many issues which would need to be taken care of. Critics see the Land Registration Act 2002 as still based on archaic property ownership principles, making it hard for the Land Registration Act 2002 to be able to solve modern challenges of property ownership. Some of the issues with Land registration Act 2002 are as follows; Under the Land Registration Act 2002, landlords have a header time dealing with registrations issues. This is especially while dealing with tenants who are not represented by a legal professional. To avoid issues, most landlords will have to avoid leasing their land for more than seven years. The Land Registration Act 2002 also requires that land owners and leasers to unregister any leases once they expire. The issue with this is the fact that most small scale owners may not be careful enough to waste their time to go unregistered expired leases. This means that the Land Register will not have data that completely reflects the status of land ownership because expired leases, which have not been unregistered from the land register, will be seen as still active. This is similar with so many other issues in the land registry that fail to give a more accurate situation of the land ownership in the country. The Land Registration Act 2002 introduced a major problem with regard to the way the land is registered. For instance, the act allows for anyone to object to a registration as long as he has a reliable ground. While this is intended to solve some ownership problems, the issue with it is that people of ill will can use it to thwart land ownership by other people. This is

Behavioural Studies Essay Example | Topics and Well Written Essays - 1500 words - 1

Behavioural Studies - Essay Example The development of motivation theory goes in the direction of individual approach to every employee. Abraham Maslow was the first to point to the fact that money and benefits aren’t the only factors motivating people. Frederick Herzberg and his colleagues carried out a broad research examining the factors contributing to job satisfaction and excellent performance of employees. As a result of their work Herzberg formulated the Motivation-Hygiene Theory or Dual-Factor Theory. Herzberg distinguished two types of separate factors. The first type are motivators resulting in job satisfaction, while the second type are hygienes, which simply prevent dissatisfaction. The motivators include: achievement, recognition, work itself, responsibility, and advancement. The hygienes are: company policy and administration, supervision, working conditions, salary, interpersonal relations, status, and security. If applied effectively, hygienes may prevent dissatisfaction, but do not provide a gua rantee of employees’ long-term satisfaction. If applied poorly, they result in negative feelings about the job. Motivators contribute to psychological growth and development on the job. They are associated with the concept of self-actualization and involve a challenge and opportunity to get pleasure of achievement and feeling worthwhile. If a manager wants to motivate people, it is necessary to concentrate on the job itself and not only on working conditions, provide opportunities for growth and development. However, this theory cannot be applied to all the employees. The practice shows that many people are quite satisfied by good working conditions and do not strive for further development. Moreover, people’s needs and goals change with time and motivators may be different in different situations, conditions and time periods. Victor Vroom argued that to make employees happy and satisfied with a job it is necessary

How women experience battering Essay Example | Topics and Well Written Essays - 250 words - 1

How women experience battering - Essay Example At the same time, social ostracism, shame and sense of hopelessness discourages them to question the violence in the relationship. Another critical issue and probably the key factor that continues to hound women is their lack of confidence in their ability to survive without their partners. They often submerge their identity in order to maintain social norms and therefore become economically and emotionally dependent on partners who abuse them. Moreover, Battered women often fail to perceive the abuse as an act that needs to be addressed urgently and therefore become victims of circumstances. The abuse is also so discordant with their expectations of love filled life that they refuse to acknowledge it as such (Ferraro & Johnson, 1983). This results in low self esteem, depression and apathy that dissuade them to rationalize the violence as such and take corrective measures. Indeed, often lonely future also becomes crucial issue which does not let them take risks and remain in abusive

Proposal - Term Paper Example This would act to speed up the lengthy intake process. These kiosks would be set up to gather at the very least the patient's name, insurance coverage, and any allergies or chronic conditions. This could help reduce the amount of time a nurse must spend with the patient just to collect background information, and therefore moves the patient to the doctor sooner for treatment or discharge. These kiosks could also be linked to the patient's electronic medical record. Ideally, these kiosks would be able to take a history of symptoms through the use of condition or symptom specific questionnaires. In this way, these kiosks would be able to assist with the triage process by alerting a charge nurse of any particularly worrying symptoms more quickly than they might otherwise have been noticed. The use of these kiosks to perform triage for milder symptoms would also free up the nursing staff to deal with patients who come in with more serious injuries and illnesses, or for whatever reason ar e unable to make use of the kiosks. This division of labor between man and machine could even make it possible for the ER to have fewer nurses on staff without detrimental effects on the quality of care. Another possible use for these kiosks would be to keep track of patients after they have been moved to treatment.

World Cinema Essay Example | Topics and Well Written Essays - 1500 words

World Cinema - Essay Example The Iranian cinema is an example of how the social and cultural perspectives and challenges are represented in the cinema. Questions of politics and religion in Iranian cinema can’t be separate from any of the films that are produced in the region. These are intertwined with the representation of culture, society’s identity and the belief systems that are continuously challenged within the region. Each era has specific approaches to religion and politics with the cinema, all which are a reflection of society at the time. Silent Era The first era of cinema that noted the religious and political views in Iranian cinema was with the silent era. The silent era was attributed to the years of 1900 - 1930 with a combination of documentaries and fictional settings that were used. The footage that was used for these specific films consisted of footage news, events and spectacles that were related specifically to royalty. These different clips were combined together to show histo rical accounts of what were occurring during a specific time and how this linked to the identity that was a part of the Iranian culture. The concept was combined with the ability to shoot rituals, religious events and to show the diversity of culture in the area, such as with investigations of Christianity and by looking at ethic and religious minorities. This approach was able to provide insight into the time frame while allowing a new type of history and sense of identity to take place through the political and religious concepts (Smith, 2006). Sound Era The foundation of film in the silent era led to new technical innovations that were approached in the sound era. However, this point also focused on the same ideals of religion and politics, specifically because it was a representation of the identity of those that were spectators to the film. The silent era had established this with the different approaches which were taken to showing the non – fiction elements of the film . From the 1930s and until the 1970s, there was a focus on providing insight into the different topics which were associated with the film. The main ideology was to present the socially engaged film, specifically which was highlighted in the 1960s. This was based on showing the realities of the Iranian culture, such as through minority groups and those which were suffering because of the current political regime and religious laws. The ideas were combined with the religious morality that was based on the Islamic practices, specifically with the belief that bringing the information to the public would also lead to a day of judgment for those who had turned away from the social issues which were at hand (Ridgeon, 2003). The concept of the â€Å"day of judgment† and the approach to religion and politics from this perspective led to the growing ideology of the third world of cinema as well as the Muslim ideologies that were engrained in the culture. The themes which were used in each of the films helped to bring light to the current issues which had been raised as well as created a sense of justice that was a part of the religion and politics. However, this was combined with the deeply embedded belief systems in the culture. The concept of religion, belief in the Quran and the continuous teachings were known and praised throughout society. The Iranian culture was expected to live under these religious beliefs, which is what created the differences and changes that were a part of society. The concept of building a Muslim ideology from the movies, while showing the concept of justice, then became intertwined with the films that were a part of the sound era (Ahmad, 2010). Modern Era The new wave, or modern era of cinema, began in the 1960s and led into 1978 with new challenges that were

Fictitious Business Description Essay Example for Free

Fictitious Business Description Essay The main purpose of this study is to discuss the importance of a Human Resource Information System (HRIS) in Castle’s Family Restaurant. We are therefore going to discuss on the HR problems in Castle’s Family Restaurant and how the implementation of HRIS will enable the company to reduce costs together with ensuring efficiency in HR operations (Randall S. Susan E. 2007). Business assessment Castle’s Family Restaurant in Northern California is the business to be assisted. It is large in size since it runs several branches in different locations and also has over 300 employees and this makes it to be a company. Depending on the size of the business, I have in my description assumed that Castle’s Family Restaurant is a since it has many employees and many branches. This assumption is based on the background of restaurant work environment and industry. Based on the basic theory of business complexity and getting work done restaurants should employ many workers to ensure that work is done efficiently like in the case of Castle’s Family Restaurant. Identified problems In the review of the HR of Castle’s Family Restaurant, I have noted the following: I have discovered that business does not have a human resource manager rather the operations manager served as HR manager. The company has not implemented HRIS which is important in monitoring the employee’s performance (Randall S. Susan E. 2007). It is therefore evident that the HR is experiencing problems since the HR manager is unqualified and had so many duties to handle which is quite tiresome for him. Some of the functions of a HR include manpower planning, recruitment and training of employees, hiring employees and monitoring employees to ensure high performance. In my analysis I will focus much on monitoring of employees performance which will help me design a business plan. The main reason for focusing on this HR function is because the company seems to have failed in its implementation of HRIS which could be useful in reducing the HR managers travel time and travelling costs and that is why the HR manager has to travel to the branches to monitors employees performance. According to the resource-based theory of Human Resources, strategic management of the company resources leads to its success (Randall S. Susan E. 2007). Increase in the costs incurred by the company is wastage of company resources since a better method can be implemented to reduce these costs and improve company’s performance. HRIS needs assessment According to Michael J. Mohan T. (2008), HRIS is an online solution used by Human Resources to enter data, track data and manage accounting and payroll functions of the company. The main purpose of implementing HRIS in a company is to reduce the manual workload in HR administrative activities through tracking existing workers. Implementation of this software will create a more efficient process from the HR in the sense that it will help the HR manager to manage information about the employees, analyze employee information, manage resumes and new applications and also complete payroll integration with other financial accounting software in the company (Michael J. Mohan T. 2008). Automating all HR functions saves a lot of time and resources and hence increasing efficiency in HR operations as suggested by the resource-based theory of Human Resources. By implementing HRIS in Castle’s Family Restaurant, the HR manager will not have to travel to all company branches to monitor and answer employees questions rather he will perform his duties in his office. All questions that need to be answered will be answered through this software. Application or implementation of HRIS in Castle’s Family Restaurant will therefore enable the HR manager to complete all of his tasks in a cost-effective manner. Conclusion As a HR consultant, I would advise Castle’s Family Restaurant to implement HRIS as this software will solve much of the HR problems and hence leading to reduced costs and improved HR efficiency. Implementation of HRIS will make the company to effectively use it resources for better operations.

Evaluating Gujarat Tourism

Evaluating Gujarat Tourism EXECUTIVE SUMMARY Gujarat has all the ingredients to become one of Indias leading travel destinations natural beauty, rich heritage, ancient archaeological sites and a colourful culture as well. Yet, Gujarat tourism has not met success in comparison to destination branding success stories such as Kerala, Rajasthan, Goa, etc. The primary aim of this study was to study destination Gujarat and probe for the reasons behind this phenomenon. A secondary aim of this study was to explore destination branding as a concept by evaluating Gujarat tourism and in the process understand how domestic and foreign tourists choose destinations for travel. The literature review highlighted issues such as critical success factors behind destination brands, growth of destination brands on the internet and the main points of the current tourism policy of Gujarat. There was a lack of information on Gujarat Tourism and hence a research was conducted which had both qualitative and quantitative components. The results from this research were used to compare destination Gujarat with three other competing states. Finally, on the basis of the research findings and analysis it was recommended that Gujarat has the potential to become a top tourist destination if it manages to create a distinct identity and strong brand associations via effective marketing strategies. INTRODUCTION Since centuries Gujarat has been a vibrant melting pot of cultures, traditions and movements. It has also been blessed with a unique natural landscape and architecture which includes ruins of a long forgotten ancient Harappan civilization at Dholavira and Lothal to the abode of endangered wildlife like the Asiatic Lion and Wild Ass not found anywhere else in the world; from the holy town of Dwarka to the glorious Modhera Sun Temple built by the Solanki rulers. Yet, unlike rival tourist states such as Rajasthan, Kerela, Andhra Pradesh and Goa, Gujarat has still not been able to fulfill its tourist potential. Much of it is due to an inability to carve out a unique identity and develop offerings which attracts more tourists. The objective of the study ‘Understanding and Evaluating Gujarat Tourism is to understand Gujarat as an emerging tourist destination and on the basis of research suggest recommendations for it to be amongst the leading tourist destinations in India. The main reasons for choosing this topic as an area for study are: * Marketing destinations provides an immense challenge to any management student in my opinion. It is an extremely complex product which has a mix of natural beauty, heritage, culture, tradition, folkart, food, etc. The study provides an opportunity to understand and analyze the marketing of such a product * Most of the academic articles that I came across on destination branding were written in a global context. A few case studies have been written on successful tourist states such as Kerela, Uttarkhand, etc. There is no recent research as such done on Gujarat tourism or its marketing and branding initiatives * Around six years ago, research had been done in MICA on â€Å"How to attract foreign tourists to Gujarat†. However, this project was not academic in its outlook and much has changed the way communication flows since then LITERATURE REVIEW Destination Branding To understand, Gujarat as a tourist brand it is imperative to understand the concept of destination branding that has been looked upon by various academicians. Tourist Destinations Tourism destinations are products of history and culture. To some level, a successful tourist destination is one which can connect instantly with the cultural background of its potential tourist. If one looks at the meanings associated with a particular place, some of them are shared by the local community whereas others are shared by global cultural communities. For example, a place like Manali or Rishikesh attracts tourists from all over the world. Hence a tourism destination may generate certain internationally shared meanings which can constitute a standardized platform from which a culturally di ¬Ã¢â€š ¬erentiated market communication can take its point of departure and provide a distinct flavor. An effective portrayal and communication of these meanings is what ultimately helps the tourist decide one place over another. Concept of Destination Brands In todays age of globalization, intense competition between destinations is forcing various states to build a strong distinct destination brand which can help differentiate one state from another and attract tourists as well as investors. To create this unique identity and build the competitive edge , it is important to study the microenvironment, tourist behavior and trends, strategies adopted by other successful tourist destinations, evaluation of its own strengths and weaknesses, etc. as a basis for coming up with effective communication strategies. Hence the marketing of places has received more increased interest and become accordingly more sophisticated over the last three decades. Also from a marketers perspective, many have shied away from the topic- arguing that places are too complex to be included in branding discussions since they have too many stakeholders and too little management control; they have underdeveloped identities and are not perceived as brands by the general public. And yet, destination branding is one of todays hottest topics among place marketers from Switzerland and New Zealand to Hawaii and Costa Rica. (Piggott, 2001) As per the World Tourism Organisation, this century will mark the emergence of tourist destinations as fashion accessories. The choice of holiday destinations will help define the identity of the traveller and in an increasing homogenous world will set him apart from the hordes of other tourists (Lurham, 1998) As style and status indicators destinations can offer the same consumer benefits as other more highly branded lifestyle accoutrements such as cars, perfumes, watches and clothes. All are used to communicate, reflect and reinforce associations, statements and group memberships and in the same way tourists use their trips as expressive devices to communicate messages about themselves to peers and observers. Travel for leisure is often a highly involving experience, extensively planned, excitedly anticipated and fondly remembered. Souvenirs and props trigger and display those experiences photographs, videos and ‘wish you were there postcards are shared with friends and relatives, and logo emblazoned merchandise and luggage labels proclaim ‘ been there, done that to any observers who care to notice. (Clarke, 2000) So, what exactly is a brand ? In marketing terms a brand represents a unique combination of product characteristics and added values, both functional and non-functional, which have taken on a relevant meaning which is inextricably linked to that brand, awareness of which might be conscious or intuitive. (Macrae, Parkinson, Sheerman, 1995) Brand advantage is secured through communication which highlights the specific benefits of a product, culminating in an overall impression of a superior brand. The image the product creates in the consumers mind, how it is positioned, however is of more importance to its ultimate success than its actual characteristics. Brand managers position their brands so that they are perceived by the consumer to occupy a niche in the marketplace occupied by no other brand- thus, for marketers, the value of a successful brand lies in its potential to reduce substitutability. Brand managers differentiate their product by stressing attributes they claim will match their target markets needs more closely than other brands and then they create a product image consistent with the perceived self image of the targeted consumer segment (Schiffman Kanuk, 2000). When consumers make brand choices about the products including destinations- they are making lifestyle statements since they are buying into not only an image but also an emotional relationship. (Sheth, Mittal, Newman, 1999). Consumers have their own brand wardrobes from which they make selections to communicate, reflect and reinforce associations, statements and memberships; in effect, ‘ consumers enrobe themselves with brands, partly for what they do, but more for what they help express about their emotions, personalities and roles. (Chernatony, 1993) When one speaks about destination branding, a few attempts have been made at defining it. Some of these definitions include, ‘Destination branding is a process used to develop a unique identity and personality that is different from all competitive destinations. ‘Destination branding is selecting a consistent brand element mix to identify and distinguish a destination through positive image building. ‘Destination branding is about combining all things associated with the place (i.e., its products and services from various industries agriculture; tourism; sports; arts; investment; technology; education, etc.) that collaborate under one brand. Its aim is to capture the essence of the destination, in a unified manner, and can be consumed simultaneously at a symbolic and experiential level. It is then used to market those unique added values to consumer needs and sustaining its success in the face of competition. From the above we can infer that destinations behave just like products. Thus they also have a life cycle of their own during which they need to constantly stay relevant and salient if they are to remain successful destination brands. Tourism area life cycle shows the stages a destination goes through, from exploration to involvement to development to consolidation to stagnation to rejuvenation or decline (also known as the â€Å"tourism destination life cycle†) Just like product brands, image is all important and how a place is represented can inspire people to visit and revisit it. (Coshall, 2000) Never was the saying ‘accentuate the positive and eliminate the negative more true than in destination branding. Destination marketing requires foresight and planning but it is not an exact science and branding offers destination marketers an opportunity to communicate key place attributes to their intended audience. Branding can help bridge any gaps between a destinations strengths and potential visitors perceptions. Place reputations are not made in a vacuum and neither are tourist choices, so place marketers must establish how their destinations image compares with those of its key competitors. How the destination rates according to ‘wish you were here? appeal and celebrity value is critical. Do tourists regard it as a fashion accessory, a must see place on every aspirational travelers shopping list or as a fashion paux- somewhere with no conversational value and even less C:UsersMIHIRDesktop1.jpgstatus. The represents a celebrity matrix and illustrates a range of destination brands measured on the axes of emotional appeal and celebrity value. Obviously, how people relate to any destination brand depends on their own individual interests, opinions and experiences, and such On any positioning map, however, brand winners emerge as those places which are rich in emotional meaning, have great conversation value and hold high anticipation for potential tourists. By comparison, brand losers are places with little meaning, even less status, virtually no conversation value and zero anticipation for tourists. Problem places are those destinations which are talked about for the wrong reasons and, far from holding an emotional appeal, actively repel potential tourists. Places which currently offer little emotional pull face an uphill task if they are to ever become destination winners. Other destinations which do have emotional pull but currently have limited celebrity value hold huge untapped potential and could be tomorrows winner destination brands. The challenge for their marketers is to craft identities for these destinations which convey and build on their emotional appeal and which turn them into places with high celebrity value. The message here is that rich, strong destination brands seem clearly differentiated and have a sense of being somewhere worth visiting. Thus, today destination brand building is all about developing a rich, relevant brand personality. ‘Developing is the key word here as successful brands never stagnate; instead they reflect and respond to changes in consumers lives while the brands core values remain the same, its personality will continue to evolve. (Morgan, Pritchard, Pride, 2002) Over a period of time, any successful destination brand will have an emotional bond with its stakeholders and more importantly the tourists who have visited the destination as well as potential tourists. An excellent example of this, is Mumbai the commercial capital of India which has over decades has established its image as the ‘City of Dreams or the ‘City that never sleeps which reflects the impact and emotional connect it has built with one and all. To successfully create such an emotional attachment a destination brand has to be: * Credible * Deliverable * Differentiating * Convey powerful ideas * Enthusing for trade partners * Resonating with the consumer A destination which is currently building such a brand proposition around its stunning natural environment is New Zealand. (Harris, 2000) A geographically disadvantaged destination, New Zealand is in the process of building a strong brand to double the countrys foreign exchange receipts to more than 3 million pounds by 2005. Delving further into the concept of brand personality for a destination brand, one can say that a brands personality has both a head and a heart its head refers to the logical brand features, while its heart refers to its emotional benefits and associations. Brand propositions and communications can be based around either a brands head or its heart; head communications convey a brands rational values, while heart communications reveal its emotional values and associations. Brand benefit pyramids sum up consumer relationships with a brand and are frequently established during the consumer research process where consumers are usually asked to describe what features a destination offers and what the place means to them. (Morgan A, 2002) The brand pyramid can be instrumental in helping to distil the essence of a destination brands advertising proposition. This refers to the point at which consumers wants and the destinations benefits and features intersect any communication should then encapsulate the spirit of the brand. The Challenge of a Destination Brand Examples of countries being influenced by external pressures to adapt and change their marketing activities or whose marketing is seriously compromised by events outside their marketers control, highlight the fact that destinations are not a single product but composite products consisting of a bundle of different components, including accommodation and catering establishments; tourist attractions; arts, entertainment and cultural avenues; and the natural environment. (Buhalis, 2000) Destination marketers have relatively little control over these different aspects of their product and a diverse range of agencies and companies are partners in the task of crafting brand identities. These could include local and national government agencies, environmental groups and agencies, chambers of commerce, trade associations and civic groups. While packaged groups normally have an obvious core- so their advertisements can anchor themselves to product performance and attributes with destinations the situation is much less clear. (Morgan Pritchard, 1999) Yet destinations have very strong and pervasive associations for tourists which if skillfully orchestrated, can provide the basis for brand building. (Baloglu Brinberg, 1997)Todays tourists are not asking ‘what can we do on holiday?, but ‘who can we be on holiday?. They are increasingly looking less for escape and more discoveries and that creates an emotional connection which marketers can exploit through branding. The challenge beyond that is to make the destination brand live, so that visitors truly experience the brand values and feel the authenticity of a unique place Factors leading to successful tourist destinations At the core of any successful tourist brand, is a clear set of brand values emotional and functional, a robust brand identity, an attractive brand personality and an efficient and targeted communication strategy. Another critical factor that impacts the brand image of tourist places is the flavor and image of the local inhabitants. Studies have proved that a places image is more often than not shaped by the ‘typical local people and their culture. Destination image, similar to the image of products and services can be seen as a multi-item construct, implying that the sum of the attributes, are the elements of  ¬Ã‚ nal composite image. This comes in line with Gensch who argues that product image is evaluated by its attributes. So, basically destination images are the result of individual attributes plus a more holistic image. The following table contains some of the critical success factors identified for destination branding (Baker Cameron, 2008): Strategic orientation 1. Visitation statistics are included and the destinations main markets are quanti ¬Ã‚ ed and segmented 2. The main competition is identi ¬Ã‚ ed 3. Tourism trends are identi ¬Ã‚ ed 4. A long-term orientation is adopted 5. The importance of international competitiveness is recognised 6. The need for infrastructure improvements is highlighted 7. The need for integration with national/regional tourism plans is recognised 8. Residents attitudes to tourism are considered 9. Local cultures, values and lifestyles are considered 10. Wealth and job creation and quality of life for residents are primary aims 11. The issue of overcrowding is addressed 12. The issue of environmental problems is addressed 13. The issue of seasonality is addressed 14. The bene ¬Ã‚ t of tourism to the destination is quanti ¬Ã‚ ed 15. Scenarios are developed Destination identity and image 16.

Local businesses were involved in planning 30. The need to improve communication between stakeholders (public, private and residents) is recognized 31. Leadership is addressed to give greater guidance to stakeholders. Implementation, monitoring and review 32. The timescale for each task is included 33. The need for monitoring and review is established Evaluating destination brands The strategic brand analysis framework comprises three main parts: * Tourist analysis, * Competitor analysis * Self-analysis. First, a destination must conduct a systematic tourist analysis. It should focus on identifying relevant new trends and developing a thorough understanding of tourists motivation for travel. Secondly, a destination should also carry out a competitor analysis. A destination needs insights into the competitors advantages and disadvantages in order to improve its own competitiveness. For example, by capitalizing on perceived niche market opportunities that rival destinations have so far failed to respond to. Last but not the least; a destination should aim to identify its true position in the market through the systematic preparation of a critical self-analysis. Highlights of the Gujarat Tourism Policy 2003-10 Objectives With a view to accelerating the pace of economic activities through tourism, the Government of Gujarat had announced the tourism policy for a period from 2003 to 2010. As per this, the following were some the key objectives * To initiate event based tourism * Chalking out of tourist circuits * Attention to be paid to tourism related infrastructure * Adoption of innovative marketing techniques and promotional tools * Developing manpower in the area of tourism * More private public relationships * Facilitation through Government policies for quick development * District Administration should play a more proactive role in tourism activities Incentives to the private sector The policy envisages privatization and incentivisation of all competitive and commercial activities of the tourism corporation of Gujarat Limited. Under this strategy the following incentives will be made available to the private sector: * Tourism will be given status of industry * Incentive package for new tourism projects * Strengthening of infrastructure facilities * Effective mechanism to build coordination with central government, state government, local self-government and NGOs * Land acquisition various tourism projects * Loan facilities will extended for tourism related projects * Better incentive packages * A special paying guest scheme to compensate for inadequate accommodation facilities * Suitable schemes for marketing tourism products * Reputed consultants will be hired to develop master plans * Decentralizing the process of development of destinations * A single window clearance system for speedy clearance Mechanism for implementation of policy For implementation of the policy, it is essential on the part of the State Government to play a facilitative role by granting necessary permissions/clearances required by investors in a time bound manner. The facilities of Gujarat Industrial Promotion Board (GIPB) set up to grant necessary clearances on fast track basis under the system of Single Window Clearance will now be made applicable to Tourism Sector also. All projects having investment less than Rs 50 crore will be approved at the Government level and the projects having investment exceeding Rs 50 crore will be approved by GIPB. The Commissioner (Tourism) and Managing Director, Tourism Corporation of Gujarat will act as the Secretariat of GIPB, for the purpose of investment in tourism projects. The Vision of the State Government for Tourism development For the growth of overall development of economic sector and social sector, the State is determined to develop tourism as a key growth sector. It has been decided by the State Government to provide condusive climate for this sector to grow and for the purpose, Tourism has been identified as the Engine of Growth. For the purpose, efforts will be made by way of promoting: * Hospitality Industry * Indirect Employment * Cultural Development * Infrastructure Development * Employment Opportunities * Sustenance of rich heritage of arts and crafts Proposed Marketing Strategy to attract tourists The State Government is keen to attract flow of tourists in the State and for the purpose, international fairs like Navratri festival, kite festival; etc will be arranged in the State from time to time. Further, the students of Gujarat shall be encouraged to develop an interest for communication through e-mail with the students and other persons abroad to interact with them about Gujarat and ultimately motivate them to visit Gujarat. Means to attract investment The policy promises for long term investment and business opportunities for national and international corporate bodies and private enterprises. The sectors like hospitality industry, eco-tourism, Viswa Gram Global village, Dinosaur theme park, Cruise trips with whale watch, Deep driving and snorkeling snorkeling of coral island, Golf Courses, Royal orient gauge conversion, Special Entertainment Zones, Wayside amenities, etc are the areas to attract further investment in Tourism Sector, leading ultimately to attract tourists flow. Relationship between Industrial Development and Tourism The massive flow of investment in industrial sector will increase the frequency of visits by executives of different industrial houses. Further, the investment in infrastructure sector in port and road, will also increase the international trade from Gujarat and particularly from the land locked states. All these developments are expected to play an important role to increase the flow of business tourists. Gujarat Tourism at a Glance Today Some of the emerging areas identified by Gujarat Tourism are as follows: Spiritual Tourism / Religious Tourism Many of Gujarats historical monuments represent the great religions of Asia Hinduism, Buddhism, Jainism, Islam, Zoroastrianism and Sikkhism. Gujarat has two Jyotirlings ( Somnath and Dwarka ), two shakti peets ( Ambaji and Pavagarh ), Narmada river (one of the seven holiest for the Hindus) and Narayan Sarovar ( One of the five holy lakes in India ). Two of the five important Jain sites ( Palitana and Girnar ) are in Gujarat besides a host of popular Jain temples spread across the state at Shankeshwar, Tarangaji, Mehsana,etc. The Dargahs of Sarkhej and Unjha hold great importance for the Muslims of India. Also, in Gujarat are Sacred Iranshaw Fire Temple at Udavada, Navsari Atashbehram and Surat Atashbehram. All three hold utmost importance for the Parsi community in the country. A number of popular spiritual gurus such as Morari Bapu, Asharam Bapu and Rameshji Oza have ashrams spread across the states. These attract followers from all over the globe. Akshardham is also a very popular temple of the wealthy Swaminarayan sect. Medical / Well Being Tourism Medical tourism is seen having a particularly high growth potential because of the availability of high-quality, low cost surgeries at Gujarats hospitals. The large population of people of Gujarati origin in America, Europe and Africa can be a major growth driver for this segment of tourism. It is home to some of the finest world class hospitals in the world such as Apollo Hospitals, Wockhardt Hospitals, etc. Care has been taken to ensure such places are set throughout the state at places such as Ahmedabad, Baroda, Surat, Karamsad, Nadiad, etc. Gujarat is also home to the ancient healing art of ayurveda and fine ayurvedic treatment has been made available to domestic as well as foreign tourists across the state. Archaeological and Heritage Tourism The archaeological zone of Champaner, Pavagadh has been acclaimed by UNESCO as the World Heritage Site1 because of its great mosques, temples, stepwells and forts. There are more than 400 archaeological sites in the Slate including some of the most substantial excavations of Indus Valley civilisation period at Lothal (near Ahmedabad), Surkotada and Dholavira Cultural Tourism Gujarat is the land of rich handicrafts like Patola weaving, khadi, bandhani, embroidery, block printing, rogan painting, matani pachhedi, namda, woodcrafts,etc. Gujrat also possesses a diverse mix of exotic communities from the camel riders of Kutch to the tribals of the hilly regions of Sabarkanta, Dangs, Chhota Udaipur, etc. Event-Based Tourism The Gujrat tourism department has created a variety of successful event properties such as Rann Mahotsav, Vibrant Gujarat, Modhera Dance Festival, International Kite Flying Festival, etc. With the celebration of festivals like Navaratri Mahotsav, Tarnetar Fair, Sharadotsav, Dangs Darbar and Kvant Fair the state intends to put the rich culture of Gujarat on the world map Business Tourism Today Gujarat has emerged as an immensely popular business destination and 55 SEZs in the state reflect the increase in business tourist, air traffic and road traffic Entertainment and Recreation Tourism Gujarat has a famous hill station in the form of Saputara. Its vast coastline of 1666km means that there are beautiful beaches all along the coast such as the one at Mandvi.

Argon Cluster and Graphene Collision Simulation Experiment

Argon Cluster and Graphene Collision Simulation Experiment Formation of Nanopore in a Suspended Graphene Sheet with Argon Cluster Bombardment: A Molecular Dynamics Simulation study Abstract: Formation of a nanopore in a suspended graphene sheet using an argon gas beam was simulated using molecular dynamics (MD) method. The Lennard-Jones (LJ) two-body potential and Tersoff–Brenner empirical potential energy function are applied in the MD simulations for different interactions between particles. The simulation results demonstrated that the incident energy and cluster size played a crucial role in the collisions. Simulation results for the Ar55 –graphene collisions show that the Ar55 cluster bounces back when the incident energy is less than 11ev/atom, the argon cluster penetrates when the incident energy is greater than 14 ev/atom. The two threshold incident energies, i.e. threshold incident energy of defect formation in graphene and threshold energy of penetration argon cluster were observed in the simulation. The threshold energies were found to have relatively weak negative power law dependence on the cluster size. The number of sputtered carbon atoms is obtained as a function of the kinetic energy of the cluster. Keywords: Nanopore, Suspended graphene sheet, Argon cluster, Molecular dynamics simulation Introduction The carbon atoms in graphene condense in a honeycomb lattice due to sp2-hybridized carbon bond in two dimensions [1]. It has unique mechanical [2], thermal [3-4], electronic [5], optical [6], and transport properties [7], which leads to its huge potential applications in nanoelectronic and energy science [8]. One of the key obstacles of pristine graphene in nanoelectronics is the absence of band gap [9-10]. Theoretical studies have shown that chemical doping of graphene with foreign atoms can modulate the electronic band structure of graphene and lead to the metal to semiconductor transition and break the polarized transport degeneracy [11-12]. Also, computational studies have demonstrated that some vacancies of carbon atoms within the graphene plane could induce a band-gap opening and Fermi level shifting [13-14]. Graphene nanopores can have potential applications in various technologies, such as DNA sequencing, gas separation, and single-molecule analysis [15-16]. Generating sub-na nometer pores with precisely-controlled sizes is the key difficulty in the design of a graphene nanopore device. Several method have been employed to punch nanopores in graphene sheets, including electron beam from a transmission electron microscope (TEM) and heavy ion irradiation. Using electron beam technique, Fischbein et al.[17] drilled nanopores with the width of several nanometers and demonstrated that porous graphene is very stable; but, this method cannot be widely used because of its low efficiency and high cost. Russo et al. [18] used energetic ion exposure technique to create nanopores with radius as small as 3Ã…. S. Zhao et al. [19] indicated that energetic cluster irradiation was more effective in generating nanopores in graphene, because their much larger kinetic energy could be transferred to the target atoms. Recent experimental works have further confirmed that cluster irradiation is a feasible and promising way in the generation of nanopores [20]. Numerical simulations have demonstrated that, by choosing a suitable cluster species and controlling its energy, a nanopores of desired sizes and qualities can be fabricated in a graphene sheet [19]. A useful tool for studying the influence of different conditions of interactions between cluster and graphene on the formation of nanopore is numerical simulations utilizing molecular dynamics (MD) [21]. The results may be useful in explaining experimental results and predicting optimal conditions for desirable graphene nanopores. In this paper, MD simulations were performed for the collisions between an argon cluster and graphene. The phenomena of argon cluster–graphene collisions and mechanism of the atomic nanopore formation in graphene were investigated. Effects of cluster size on the threshold incident energy of defect formation in graphene were also discussed. Molecular Dynamics Method MD simulations were performed for the collisions between an argon cluster and graphene. For present simulations we used an effective code LAMMPS stands for Large-scale Atomic/Molecular Massively Parallel Simulator, written by Sandia National Laboratories [22]. Length (along the X axis) of the graphene layer was 11 nm, its width (along the Y axis) was 10 nm, and each layer contained 3936 atoms. Periodic boundary conditions were applied to both lateral directions. In the simulation, the Tersoff–Brenner empirical potential energy function (PEF) was utilized to simulate the energy of covalent bonding between carbon atoms in the structure of graphene layer [23-24]. The initial configuration was fully relaxed before the collision simulations and the target temperature was maintained at 300 K. During the collision phase, a thermostat was applied to the borders of graphene. The Ar nanocluster was arranged by cutting a sphere from FCC bulk crystals, which had no initial thermal motion. The Ar cluster was initially located above the center of graphene at a sufficiently large distance so that there would be no interaction between the Ar and graphene atoms. Then, a negative translational velocity component, Vz, was assumed for each atom of the clusters. Incident angle of the argon cluster to the graphene normal was zero. Lennard-Jones (LJ) two-body potential was employed to simulate the interactions of Ar–Ar and Ar–C atoms. The form of LJ potentials was: (1) In the LJ potential, is the distance at which the potential is zero and is the depth of the potential well. Note that the constants were obtained from the mixing rules given by ÏÆ'ij = (ÏÆ'i+ÏÆ'j)/2 and Ô ij = (Ô iÔ j)1/2. The parameters for Ô  and ÏÆ' used in the present simulation are shown in Table 1[25]. Position of the atom was updated by the velocity Verlet algorithm with a time step of less than t = 0.5 fs. To reduce the calculation time, a cut-off length was introduced. The Van der Waals interaction of Ar-Ar and Ar-C atoms with the distance of 11A or above was neglected. Result Studying the effect of incident energy in ranging 1–120 ev/atom was chosen to demonstrate two distinctive phenomena: (i) Argon atoms were just reflected, and (ii) some argon atoms penetrated through graphene. Fig. 1 demonstrates the probabilities of reflection and penetration of the Ar55 cluster. Fig. 2 shows the snapshots of the deformation of the graphene sheet due to the collision with an Ar55 cluster in the case of the incident energy of less than 11ev. During the collision, graphene was bended in the circular region around the collision point and the transverse deflection wave was observed. After the collision, argon cluster was bursted into fragments. Fig. 3 shows the final atomic configurations resulted from the incidence of Ar55 cluster with the energy of 10 and 11 ev/atom. There were two possibilities for the structure of the graphene sheet after the collision: (i) the graphene was rippled after the collision and no damaged region was formed, this was observed in case of the incident energy of less than 11ev (Fig. 3(a)), and (ii) the collision caused defect in graphene (Fig. 3(b)). Fig. 4 shows that there were two possibilities for the structure of the graphene sheet after collision with an Ar55 cluster in the case of the incident energy of greater than 11 ev/atom: (i) the argon cluster penetrated into the graphene sheet without the sputtered carbon atoms (Fig. 4(a)), and (ii) the argon cluster penetrated into the graphene sheet with the sputtered carbon atoms (Fig. 4(b)). When the incident energy of argon cluster was 11ev/atom, atomic-scale defects such as Stone−Wales defect were formed in the graphene sheet (Fig. 3(b)). With the increase of the incident energy, these atomic defects began to get connected and finally a nanopore with carbon chains on the pore edge was created in graphene. The atomic carbon chains with unsaturated bonds thus provided the method for chemical functionalization of graphene nanopores in order to improve their separation ability and detection. For example, oxidation of packed multilayered graphene sheets was significantly perme able to water and impermeable to He, N2, Ar, and H2 [26]. Accordingly, it was necessary to introduce the concept of threshold incident energy of defect formation (Ed) in graphene and threshold energy (Ep) of penetration argon cluster in graphene. Fig. 5 shows the size dependence of each threshold incident energy. Thus, both Ed and Ep were supposed to be written in simple power-law equations: In Eq. (2), Ed(1) and Ep(1) indicate the threshold energy for argon atom, and N is cluster size. Power indices on N, ÃŽ ±, and ÃŽ ², mean the degree of non-linear effect. (2) Fig. 6 shows the final atomic configurations resulted from the incidence of Ar55 cluster with the energy of 14 , 15 ev/atom. By further increasing energy, the carbon chains became short and the pore edge became smooth we calculated the number of sputtered carbon atoms as a function of total incident energy, because the number of the sputtered carbon atoms was in correspondence to the area of nanopore in graphene. Fig. 7 shows the number of sputtered carbon atoms as a function of total cluster energy in the case of Ar19 and Ar55 cluster collision. For both cases, as the total energy increased, the number of sputtered carbon atoms increased. This result was in agreement with the previous study [27] .The number of sputtered carbon atoms can be approximated by a constant value for incident energy larger than 10 Kev. The cluster collision with large size led to higher the number of sputtered carbon atoms when all clusters had the same total cluster energy. Conclusions The phenomena of argon cluster–graphene collisions and mechanism of the atomic nanopore formation in suspended graphene sheet were investigated using molecular dynamics method. Summary of the obtained results is as follows: Threshold incident energy which caused defect formation (Ed) in graphene and penetration (Ep) into argon cluster were introduced. Simulation results for the argon cluster–graphene collisions showed that the argon cluster bounced back when the incident energy was less than Ed and broke when the incident energy was greater than Ep. Suspended carbon chains could be formed at the edge of the nanopore via adjusting the incident energy and, by increasing energy, the carbon chains became short and the pore edge became smooth. Ed and Ep were found to have relatively weak negative power law dependence on cluster size. The cluster collisions with large size led to higher the number of sputtered carbon atoms when all clusters had the same total cluster energy. References [1] K. S. Novoselov,A. K. Geim, S. V.

Spanning Two Decade?s:The 50?s to the 60?s Essay -- essays research pa

Spanning Two Decade’s: The 50’s to the 60’s Similar? Or Distinctly different? â€Å"The postwar years are remembered as a time of affluence, consumerism, conformity, and stability, a time when American enjoyed an optimistic faith in progress and technology.†(Heretta, pg.779) These words best describe the decade that Americas experienced in the 1950’s. It was age of dad’s always-right attitude and a culture that was family centered. The standard of living for American’s was the best in the world. The times just looked to perfect lives were lived to privately. This private enjoyment was centered on the family, leisure, and consumerism. Soon everyone tried to become to â€Å"Leave it to Beaver† type of family and culture exploded. The explosion is what everyone considers to be the 1960’s. Kids that grew up in the fifties were becoming teenagers. The pressures from their parents turned the sixties generation onto conceptual thoughts and radical behavior. This affected the ideals of politics, racial/gender discrimination, a nd family values. The differences between the fifties and the sixties are extremely evident but you must closely sort through the decade to find the definite similarities. The similarities and differences come in many political values, and behaviors.   Ã‚  Ã‚  Ã‚  Ã‚  What does the word â€Å"consensus† refers to? â€Å"It is the conformity to social norms, authority, and the status quo.† (Henretta, pg. 790) It best refers to the decade of the 1950’s, where families were attempting to escape into â€Å"old home grown† households, away from the Red Scare, and out of the corporate jungle. To do this, these families flocked to the suburban area. Early in the fifties a massive â€Å"Baby Boom† occurred. With the high birth rate the need for churches caused the ideas affluence, consumption and conformity to swell in importance. With the war in the past, the fifties generation looked towards the church. Families started to make Sundays a priority in their lives. â€Å"Church membership rose from 49 percent of the population in 1940 to 69 percent in 1960†(Henretta,792). All denominations from Catholics to Jews rose in membership. Even separation between church and state became less define when in 1956 they added â€Å"In God We Trust† to coins and â€Å"Under God† in the pledge of allegiance. One of the major use of religion was not only to reach savior but also to help deal with th... ...onfidence. From Washington's perspective, the principal threat to U.S. security and world peace was monolithic, dictatorial communism emanating from the Soviet Union. Any communist, at home or abroad, was, by definition, and enemy of the United States. Drawing an analogy with the unsuccessful appeasement of fascist dictators before World War II, the Truman administration believed that the United States and its allies must meet any sign of communist aggression quickly and forcefully. This reactive policy was known as containment. The idea of containment was very similar to the McCarthyism.   Ã‚  Ã‚  Ã‚  Ã‚   The fifties and sixties signified two decades of affluence, consumerism, and conformity while wading through the changing of society . Teenage counter-culture, religion, politics, communism, and social views became pivotal views of expression during this time. You must observe all these assets to draw a valid conclusion of your own, but to collected facts that have been presented have graciously swayed one way. The difference between is the fifties and the sixties are extremely evident, but you must closely sort through the decade to find the definite similarities.

Descriptive Essay - Our Mountain Cabin -- Descriptive Essay, Descriptiv

Our Mountain Cabin The ruckus from the bottom of the truck is unbearable, because of the noise and excessive shaking. As we slowly climbed the mountain road to reach our lovely cabin, it seemed almost impossible to reach the top, but every time we reached it safely. The rocks and deep potholes shook the truck and the people in it, like a paint mixer. Every window in the truck was rolled down so we could have some leverage to hold on and not loose our grip we needed so greatly. The fresh clean mountain air entered the truck; it smelt as if we were lost: nowhere close to home. It was a feeling of relief to get away from all the problems at home. The road was deeply covered with huge pines and baby aspen trees. Closely examining the surrounding, it looks as if it did the last time we were up here. We slowly crept around the corner, finally sneaking a peek at our cabin. As I hopped out of the front seat of the truck, a sharp sense of loneliness came over me. I looked around and saw nothing but the leaves on the trees glittering from the constant blowing wind. Catching myself standing staring around me at all the beautiful trees, I noticed that the trees have not changed at all, but still stand tall and as close as usual. I realized that the trees surrounding the cabin are similar to the being of my family: the feelings of never being parted when were all together staying at our cabin. As I walked closer to the cabin, which has been abandoned since last summer, I noticed certain materials are stored away, for the winter, such as the grill, which is taken off the hinges around the fire pit, and put underneath the cabin deck. The canoe is upside down and tightly snugged underneath the cabin deck. I also noticed the picnic tab... ...ing used to them not living with me for college, I've realized that the cabin reassures the family bond, we have so greatly between each other, and gives the family hope that we can always have a place where the family, as one, is welcomed. Although we live in different cities, this place gives me the belief that my family will always be there. When the whole family is up at the cabin, it seems as if nothing has changed, as if the pine trees have not grown apart, or any taller. Th pine trees drop their children (pinecones) right next to the parent, never being able to leave. This symbolizes the feeling I get about my family while being up in the mountains at our cabin. We then turned off the driveway, making sure to roll down our windows, so we can breathe the fresh mountain air, at least until the next time we come back, and once again start the bumpy road home.

Sustainability and Environmental Standards

Sustainability and Environmental Standards: Seeking Competitive Distinction at Damai Lovina Villas . Executive Summary Throughout this analysis, my purpose is to clarify and condense the information so the reader will have a better understanding at the end of the analysis. This analysis will be broken up into six categories; the executive summary, issue statement, alternatives analysis, recommendations, actions and implementations, and data analysis. In the issue statement, there will be a brief overview on how the hotel companies and the environmental regulations clashed.Throughout the alternative analysis we will discuss different alternatives that Damai could have focused on to benefit and sustain his hotels. As we move to the recommendations our group will give clear advice on how we would’ve handled the situation. Actions and implementations will implement the steps that Damai took to clean up his name and benefit the locals that were on the island. The data analysis will be a break up of data to better explain the situation at hand. Issue Statement:One of the major issues impacting the Hotels was that the environmental regulations were lacking since existing standards were not enforced and growth often was promoted to the detriment of the environment. For years the Balinese government had promoted sand dredging to enlarge the island for more hotel development off the port of Benoa. By the continued dredging of the sand, this would in effect alter the water currents and the new currents have eroded the natural beaches bordering the town Sanur.Dredging projects rarely involved environmental impact studies or guaranteed protection of natural areas as required by law. Tourism was the island only source of income, but this source of income was causing serious social and environmental problems. For example the drinking water often slowed to a trickle during daylight hours due almost exclusively to the high demand for water in the resort area of Nusa Dua. Also the lack of a centralized waste collection system has encouraged alternative solution such as the formation of an informal collection system.Many hotels and residents left used paper and plastic outside of their properties. Despite these challenges the system successfully diverted a significant amount of waste from the landfill. Data analysis: As the benefits of advertising proactive environmental efforts were recognized by global hospitality hotels targeted environmentally conscious customers to gain competitive advantage as a result of which helped non luxury hotels command premium prices of $30/night in a very competitive industry. Marketing sustainability shows that participation in a VEP could be costly depending on the program.Adopting a formal EMS and certifying it IDO 141001 may typically cost $270-$1370 per employee depending on the extent to which the company had instituted proactive environmental and continual improvement procedures prior to implementing a formalize d Ems. Although more than a dozen VEPs and eco-labeling programs targeted the hotel industry by 2006 only handful of these were available to Indonesia hotel. Alternatives analysis: Damai has several alternatives to ultimately benefit and sustain its hotel.Damai could of considered voluntary environmental programs and take the risk of the hotels luxury to take a negative impact by lacking integration that can possibly have a major impact in the long run. Another alternative damai could of pursued was a better marketing strategy that fully described everything about the hotel in regards to its environment, community status overall. This could have been achieved through a brief slideshow that offered key components of information on the website or brochure developed by Damai.Damai should focus less on advertising its produces of food and more on the sustainability efforts. A better description and more detailed amount of information given about the hotels sustainability efforts along w ith other factors will ultimately create more attraction for business. Recommendations: So at to expand capacity by constructing additional rooms, Damai should ensure that existing room were filled and that the restaurant operated above its current 65% occupancy. This will bring improvement in the business as Knape hoped to better integrate Damai into the local network of eco-hotels and eco-tours.Damai should continue to rely on its website and local travels agents to promote the hotel’s sustainability vision because Damai’s website was the primary vehicle for marketing hotel’s various sustainability efforts which directed environmentally conscious customers to an organic resort link to learn about the hotel’s sustainability vision. Besides, these local travel agents will play an important role by promoting the hotel’s sustainability vision to customers, which will benefit the industry. . Action And Implementation:Through a partnership with IPSA, D amai helped the farming and fishing communities remediate the effects of management techniques that could be harmful to the environment and public health. The burning of agriculture impaired air quality and human health, which comes from the hundreds of small farms that operate in a single community. The hotel work towards teaching farmers composting methods and organic growing practices, using IPSA products to increase the pace of decomposition. Damai utilized a water recycling system that directed used guest water to on site tanks.All wastewater was filtered through a series to tanks containing volcanic rock, porous rubber, and sand and then reused in the hotel gardens. Even waste from the toilets, was then collected and treated using natural enzymes to break down the organic waste. This waste was then passed through a series of filters and re used in the hotel gardens. One of the hotel big implementations came when it decided that they should join forces with local farmers to rec laim eroded topsoil. Damai built a series of large rock wall filters in the river that ran through the property creating a series of waterfalls.At the bottom of each waterfall was a large pool of water that captured much of the topsoil from the hotel pools to reduce the need for chemical fertilizers. Question: 1. The relationship between tourism and social/environmental issues in Bali was every thing that was resulted from tourism had impacts on society and environment of Bali. Although tourism plays an important role in Bali’s economic growth and financing, it also caused serious social and environmental problems. Bali’s hotel alone required 260 liters of water per second, which was an amount equivalent to the typical water consumption of 50,000 villagers when drinking water in Denpasar often slowed to a trickle during daylight hours due almost exclusively to the high demand for water in the resort area of Nusa Dua to the south. Besides this Hotel and retail chains ha d avoided locating in Lovina Beach of Bali because it was less accessible than South Bali. 2. Bali’s environmental status was affected by different government polices like the government’s focus on energy development and resource extraction, close relationship with developers, and lack of budgetary caused many citizens to lose faith in its ability or intent to protect Bali’s environment.Environmental regulations in Bali was lacking since existing standard were not enforced and growth often was promoted to the detriment of the environment. The Balinese government had promoted sand grudging enlarging the island for more hotel development off the port of Benoa. Dredging projects rarely involved environmental impacts studies or guaranteed protection of natural areas as required by law and when they did was almost never monitored for accuracy. The island had one government-operated landfill that was located outside Denpasar on reclaimed tidal land.Like many landfills in emerging economies, it lacked controls to guard against groundwater contamination. 3. Firms did not need to wait for government in order to take action in addressing Bali’s social and environmental issues. Many Balinese began to get discouraged of how the government handled the environmental and social issues that occurred. Instead Balinese citizens took matters into their own hands and decided to rely more on communal code guided by strong social norms to influence behaviors 4. Damai’s focus was to sustain and distinguish their hotels.Since damai did not participate in the idea of voluntary environmental programs they were able to avoid the luxury status of the hotel to downgrade. It complemented the sustainability program because the hotels reputation remained the same by relying on other factors such as the website and travel agents that have the potential to create a positive impact. 5. There are numerous sustainability activities Damai had already implemented. Which activities can be described as pollution prevention, product stewardship, clean technology/innovation, and sustainability vision?Pollution prevention: Damai has made an impact on the local surrounding when it comes to preventing pollution, for example normally at the end of each growing season, traditional farming practices involving the burning of agriculture waste to generate ash for the fertilizing of the next year crops. But hundreds of farmers in the community lack the knowledge on how the burning of agriculture impaired the air quality and the human health. The continued of burning of agriculture drive a greatly needed source of income which is tourist away from the community due to poor air quality.Damai solution for this is through partnership with local farmers to educate them about different ways of making fertilizer, which is through the different composing methods and organic growing practices using products from IPSA, which would increase the pace of decompositio n. Product stewardship: Damai shift from paying a deposer contractor to lovina Beach, to pick up the hotel’s solid waste, which transports the waste back to a dispensary, had proven costly. So Damai develop an environmental efficient way by transporting plastic and bottle containers to their respective suppliers to be recycled and reuse.To save cost of the purchasing of the purchasing of water, the Damai hotel use waste from the toilets, which are collected and treated using natural enzymes to break down the organic waste. This waste then passed through a series of filters, which is then re-used in the hotel’s gardens. By doing this implementation of treating waste from the hotel, Damie water conservation efforts reduced hotel water use by 75%. Clean technology/innovation: Hotel works closely with local famers and village leaders to develop the best possible way to reclaim the community eroded topsoil.The eroded topsoil came about because of traditional irrigation wate r systems, and monsoon rains, which caused fertile topsoil to flow from the rice paddies and drain into the ocean. The problem of the loss of topsoil loss prompted more farmers to rely on chemical fertilizers to grow their crops. Damai address this issue by building a series of large rock wall filters in the river that ran through the property creating a series of waterfalls. At the bottom of each waterfall was a large pool of water that captured much of the topsoil lost from the seven villages surrounding the hotel.This showed the hotels continued efforts to better the community through is efforts, Damai went on to encouraged the local farms to reclaim their topsoil from the hotel pools to reduce the need for chemical fertilizers. Sustainability Vision? The hotel had chosen to refrain from promoting its sustainability focus in guest rooms, restaurant and gardens. Damai also decided not to involve guest in an optional linen reuse program in order to maintain its luxury status, even though such programs had become popular in the US and European hospitality industry. . How does Damai’s current sustainability focus compare to the environmental performance criteria listed in the VEPs listed in case Exhibits C-H? Damai did not participate in any VEPs. However, the hotel was considering if it would be beneficial for the hotel to participate in the VEPs. Damai was not able to expand its capacity by constructing additional rooms; the most important way to improve the hotel was to ensure that existing rooms were filled and that the restaurant operated above its current 65% occupancy.By doing this, Damai had integrated itself into local network of eco hotels and eco tours. Damai has different sectors in which its market itself whether marketing through its website which directed environmentally conscious customers to an â€Å"organic Resort† link which help customers learn about the hotel’s sustainability vision. Damai provided travel agents with in formation about the hotel, some the travel agents began to market the hotel as being environmentally conscious by advertising that Damai produces 80% of its food local gardens. 7.Best Green Hotels and others have no financial charge listed. A 10% expense on lodging charge has to be paid by the owner that lists on the Eco Lodge even though the website is free of charge to utilize. The number of rooms and workers determine the fees for Global Green 21. Hotels with less than or equal to five workers or less than ten rooms pay $395, whereas hotels with less than or equal to 50 works or 70 or less rooms pay $1610. An independent external auditor must also be appointed along with the cost of becoming ISO 14001 certified. . I recommend that Damai join the Eco Lodge Program. The program offers ways to tutor guests and staff of environmental protection by recycling trash and water. Partaking in this program allows Damai to network with members who are not wasteful and proved to contribute to environmental protection. It also gives his future customers a way to view Damai on the Internet, which has over 600 travel agencies. Although there is a 10% commission it doesn’t compare to the benefits Damai will receive from being on the site.

Boy at the Window Poetry Analysis Essay

In the poem â€Å"Boy at the Window,† Richard Wilbur uses imagery, tone, and theme to show what his purpose in this poem is. At the end of the poem, the author wants the reader to understand that we should not feel bad or sad about something that we don’t understand. Richard Wilbur’s use of imagery in the poem helps us to understand his purpose of this poem. The stanzas in the poem paint two completely pictures in your head when you read them. The first stanza makes you see the snowman as a blue object that is always lonely. The second stanza paints the picture of the snowman’s view of the little child who is sad about something that he does not understand. In the first stanza, the poem is showing how the little boy sees the snowman â€Å"standing all alone† and â€Å"returns him such a Godforsaken stare†. The little boy sees the snowman as lonely and creates a depressing image of the snowman in your head. In the second stanza, you hear the snowman’s view of the little child in the window and how the little boy does not understand. The snowman is shown as sad in the second stanza, but not because the little boy does not understand that the snowman is happy outside. It is because the little boy should not be sad when he is warm inside his home, surrounded by love, but yet so frightened and moved about the snowman being alone (â€Å"such warmth, such light, such love, and so much fear†). So the author creates a really great sense of imagery throughout the poem because of how you see the snowman at first, then the picture in your head changes when you hear the other side of the story. The author also had a great tone throughout this poem as he shows us his purpose and his theme that people should not be sad or fear something if they do not understand it. The tones of the stanzas vary or differ when you go from to the second stanza. In the first stanza, the tone is sad or deeply upset because of the word choice that the poet uses. When the boy â€Å"weeps†, you get the feeling of sadness and that the boy is not happy. Also, the child’s sight is described as â€Å"tearful† and his reach described as â€Å"hardly†; which are words used to describe saddening events. The snowman is seen as a â€Å"pale-faced† figure and is compared to the â€Å"outcast Adam†. These words are not used to describe a happy or content situation, and they are describing a sad view of a snowman. In the second stanza, the tone is happier, but not completely joyous or happy. The snowman is â€Å"nonetheless, content† so he is not sad being outside or being all alone. The snowman’s eye is seen as â€Å"soft† and his tear is seen as â€Å"a trickle of the purest rain†. When you use the word â€Å"purest† it doesn’t relate to sad or happy events because the word describes a neutral event. The poet creates a great tone throughout the entire poem, which is sad for the first stanza and kind of neutral for the second stanza. Using imagery, tone, and theme throughout the poem â€Å"Boy at the Window†, Richard Wilbur shows that you shouldn’t feel bad or get upset about something that you do not understand. The author’s use of imagery in the poem is what paints a wonderful picture in your head as you read, and that helps you to understand the author’s purpose. Tone plays a big role in the poem also because of the way you get to hear the different sides to the story and how that impacts the author’s purpose and how it’s portrayed. This poem was very well written and did a very good job of using literary elements to portray the author’s purpose and the theme.

Measurement of Biochemical Oxygen Demand (Bod)

Title: Laboratory 2: Measurement of Biochemical Oxygen Demand (BOD) Objective To determine the amount of oxygen necessary for biological oxidation of wastewater effluent and determine the amount of oxygen required by bacteria while stabilizing decomposable organic matter. Methodology Apparatus ; Biochemical Oxygen Demand (BOD) meter, Dissolved Oxygen bottle (DO bottle), pipette, Teflon tape, dilution water, incubator machine. Procedure; Add 300 ml dilute water then take DO reading immediately Closed properly and keep into the incubator (200C).Take reading for the next 5 days Add 3 ml dilute water and fill up with dilute water until 300ml then take DO reading immediately Figure 1 Precaution Samples for BOD analysis may change greatly during handling and storage. Testing should be started as quickly as possible. To reduce the changes in those samples which must be held, keep the samples at or below 4 °C. Do not allow samples to freeze. Samples may be kept for no more than 48 hours be fore beginning the BOD test. Students assign to prevent interference from chlorine. Because chlorine is such a strong oxidizing agent, it will inhibit the growth of living bacteria in the BOD test.Any samples containing residual chlorine must be pretreated to remove chlorine before the test is run. This is done by adding sodium sulfite to the sample. Samples with extreme pH values and samples containing disinfectants such as residual chlorine must be treated prior to testing. Caustic alkalinity or acidity can prevent bacteria from growing during the course of the BOD test. To prevent this, samples which have pH values higher than pH 8. 0 or lower than pH 6. 0 must be neutralized to pH 7. 0 before the test is performed.

Since that, it does not suitable and can’t be used to calculate the BOD level. BOD test is a biological test; dependent on the actions of t he microorganisms found in the wastewater and, as such, is subject to a number of variations. These variations can be caused by a number of factors, including changes in temperature, weather, composition of incoming sewage, in plant operations, and sampling points.Results can vary widely from day to day, or even hour to hour. . Form the result we found that the the BOD level in group 5 is 128mg/L, Group 4 72mg/L is quiet higher rather than Group 1 39mg/L. When BOD levels are high, dissolved oxygen (DO) levels decrease because the oxygen that is available in the water is being consumed by the bacteria. Since less dissolved oxygen is available in the water, fish and other aquatic organisms may not survive. If referred to the IWK website, BOD5 at 200C is 20mg/L for standard A and 50mg/L for standard B.Its mean only sample from group 1 is under control and can be entitled as clean. High level of result from group 4 and 5 may resulted by the input of nitrates and phosphate. Nitrates and phosphates in a body of water can contribute to high BOD levels. Nitrates and phosphates are plant nutrients and can cause plant life and algae to grow quickly. When plants grow quickly, they also die quickly. This contributes to the organic waste in the water, which is then decomposed by bacteria. One of the major disadvantages of the BOD test is the time lag between the collection of samples and the final calculation of results.This makes the BOD test a poor test for determining whether or not operational changes are needed. In addition, the rate and degree that organic matter in wastewater is decomposed (or oxidized) by the normal bacteria present in a sample is largely dependent on the characteristics of the organic matter. For example, some organic matter (like sugars or starches) are oxidized very easily and rapidly, and will almost always result in measurable â€Å"BOD†. Other organic matter, however, is sometimes resistant to biological oxidation, and may require spec ial â€Å"acclimated† bacteria to oxidize the material and to show a â€Å"BOD†.Although this is what actually happens in nature, it causes significant variation in BOD results from sample to sample. Conclusion, high; level of BOD reflects to the DO which it will be decrease. Which is mean the water quality if poor. References Unknown. (n. d. ). Indah Water.
