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.

English as official language of the United States Essay

â€Å"News from 2000 Census is that 49 percent of Hispanics in America are not fluent in English. They are the fastest growing minority in the United States, representing 12. 5 percent of the population. The legal picture for Hispanics is also astonishing. EEOC complaints have more. than doubled in 5 years, and settlements have risen to over $50 million. † (Harrop, 2001) The inhabitants of the United States have never had any official language. Over 6 % of primary school children in the United States were instructed in German until the World War I. Over 45 million American nationals still state that their forefathers spoke German. Large scale immigration in the 20th century led to the inhabitance of multilingual people inside the US. Therefore, around 336 different languages are presently spoken which comprise of 176 endemic dialects. More than 47 million American nationals use a language other than English within their homes including 30 million Spanish speakers. Since a significant number of US nationals feel comfortable while speaking a language other than English, the federal government should not make English the official language of the United States. The US Senate voted to select English the official language and prohibited the use of other languages for federal government orders and services. â€Å"The 63-34 vote, on an amendment offered by the Oklahoma Republican James Inhofe, split the Senate along largely party lines, with only nine of the 44 Democrats voting for it, and just one Republican voting against. † (Cornwell, 2006) Democratic minority leader Harry Reid identified this amendment as â€Å"racist† whereas Ken Salazar, a Colorado Democrat of Hispanic origin, described it as â€Å"divisive and anti-American†. (Cornwell, 2006) Such a law neglects any provisions for services in languages other than English. This would be a problematic situation for those Americans who cannot speak English fluently. This would also force new immigrants to have considerable knowledge of English language before they get US nationality. It is surprising to note that English language voted out German by a difference of just one vote when it was selected as the official language of the US by Congressmen in the year 1795. (Cornwell, 2006) â€Å"Enacted at the apex of the Great Society, the Bilingual Education Act was passed by Congress and signed into law by President Johnson without a single voice raised in dissent. Americans have spent the past 30 years debating what it was meant to accomplish. Was this 1968 law intended primarily to assimilate limited-English-proficient (LEP) children more efficiently? To teach them English as rapidly as possible? To encourage bilingualism and biliteracy? To remedy academic underachievement and high dropout rates? To raise the self-esteem of minority students? To promote social equality? Or to pursue all of these goals simultaneously? The legislative history of the bill provides no definitive answer. † (Crawford, 50) English Only Movement The English Only Movement (EOM), a movement initiated in the 1980s, is a sequel of the procedure of domestic colonialism. This will also lead to the demolition of the other languages which are spoken by minorities. In the year 1979, a Report by Carnegie Corporation pointed out that â€Å"bilingual education was the preeminent civil rights issue within Hispanic communities. † (Penna, Shepherd, pg. 147) Bilingual education also became a key issue creating distress in the Mexican community inside the United States according to different researches carried out by the U. S. Civil Rights Commission ( 1967- 1975). Researches also reveled that the academic system inside the US was thought of as being against the cultural traditions of the Mexican population. This led to negative effects including inferiority complexes amongst the Mexicans. There is no doubt in the fact that the eradication of a community’s traditions and customs is an abuse of the basic civil rights regarding the linguistic and cultural survival of a specific community. On the domestic level, the English Only amendment in the state of California was a triumph for those who support the use of English as an official language. It gave legal status to an issue that goes against biculturalism and bilingualism. During the period between 1986 and 1989, voters and legislators in thirty-nine states took into account plans analogous to the Californian amendment. This led to the appearance of 17 states with English as the official language. The English only third house had been succeeded in bringing bilingual education policy to the leading position of national debate, it includes questions, the approach of scientific teachings of bilingual education and it also contains a federal resolution in this could help English be official language of the United States. Law at the highest point of the great society, the bilingual education act was passed by congress and it was signed to become a law by President Johnson without saying a single word against it. Americans, have spent thirty years in discussing that what it meant to achieve. â€Å"Was this 1968 law intended primarily to assimilate limited-English-proficient (LEP) children more efficiently? To raise the self-esteem of minority students? To promote social equality? Or to pursue all of these goals simultaneously? The legislative history of the bill provides no definitive answer. † (Crawford, 50) Melting Pot Theory The discussion over, if the United States is an assimilationist or form a society embracing many minority groups and culture traditions which are very old. There were some exchanging of views forcefully that United States is a melting pot, which means that people of various nations settle in America and forced to resemble which means to become an American completely. â€Å"The March 14 to 16 poll of 1,007 likely voters with a margin of error of three percentage points showed that 63 percent of Americans would like to have ballots and voting materials only in English, compared with 35 percent who wanted them printed in English and other languages. † (Lawmakers Push Official English, A06) Because these declarations repeat the study of Myths of the Melting Pot, as well as spread throughout wrong ideas about languages which are mostly not challenged but nothing is supported by the record of history. In fact, history of the US language policy – or lack of one – both work at lower price than the logical basis for official English and provide warning lessons about teaching actions to restrict languages which are rarely use. 1. Unfavorable to myth, the United States has never been a basic speaking and/or using only one language country. By the period of time, one from eight of permanent inhabitants reported a languages background other than English in 1976, this is variety of nothing new but some skilled persons in languages or study of languages believe that the United States has been the habitant of more persons able to speak two languages than any other nation in the history of the world. As early as 1664, when the colony of the New Netherlands came into possession of British, eighteen different languages were spoken on Manhattan Island, not including the language spoken by the local inhabitants of America which were numbered more than five hundred in North America at the time. 2. Considering the US history, the prevailing federal policy on languages has only maintained tolerance and adjustments. In spite of the language variety in 1787, the famous took no interest to protect or encourage English: United States constituents. Because discussion were held in private and we must depend on James Madison’s informal notes, it is not clear, if any language issues came up during the federal agreement on social behavior in Philadelphia (Farrand 1913). But available facts strongly suggest that our early leaders regarded language laws of any type as a cause of harm to civil freedom from captivity. 3. Recognizing about rarely spoken languages reflected bilingual and non-English – language schools which were ordinary in many districts until the long time period of World War I. In 1710, British missionaries were invited to maintain schools among the Iroquois League of Ally States, with the demand that students should be informed or taught with their national languages. Parts of bible which were translated in Mohawk language were included in the texts used. In 1802, Congress began a yearly devotion of ($15,000) to encourage â€Å"civilization among the old inhabitants (before the arrival of colonists). † This money was devoted to religious schools in which many schools were bilingual. 4. The liberation policy on languages was the best and ideal policy for this country, but it is no upheld especially among people conquered and angry for supposed un-justice; people living in colonies and some racial people. Attitudes of the 19th centuries towards their right of language were considerably less tolerant than say towards speakers of German, French or Scandinavian languages Conclusion As written in this paper, there are many ways that lower class is being saved from being forgotten in the US. For his reason, it is important to be known by the mysterious ways in which this is happening. Language is another simple of making sure that the class’s position in society is prevailing. â€Å"English as the nation’s dominant language is no more threatened at the turn of the 21st century than it was at the turn of the 20th. To the contrary, it is all the other languages that are endangered – and would soon die out, if not for the replenishing effects of immigration. † (Official English/English Only, n. p. ) It has been as issue for decades that some influential groups/people have been trying to restrict other languages and promote English Language. On the other hand, this policy has not been accepted and approved by the majority of Americans as it is discriminatory. This idea is not hidden that making English as the US official language is the agenda of White Americans – it also unveils the approach of White American as they don’t want more immigrants from the third world countries.

Parallels essays

Parallels essays In Charlotte Brontes masterpiece, Jane Eyre, of the Victorian period and the Romance of Tristan and Iseult, as retold by Joseph Bedier, the couples that find themselves in love are Jane Eyre with Edward Rochester, and Tristan with Iseult. Both couples face major obstacles that jeopardize or destroy their relationship. Some of the characteristics of romantic love used in these two works are suffering for one another in a variety of ways, constant thought of one another, and most vital to these particular tales, the overcoming of obstacles. The parallels between the two novels extend beyond these, but there are some obvious differences. In both novels, the love of the two protaganists is forbidden by social obstacles, all very important. In the case of Tristan and Iseult, it is the marriage of Iseult to King Mark, and in Jane Eyre and Edward Rochesters instance, it is Edwards marriage to Bertha, his insane wife who is contained in the attic. Iseult and Mark could never be divorced, as that was not an option in feudal times. Edward and Bertha also could not be divorced, for several reasons. The only truly acceptable cause for divorce in Victorian times was infidelity. Bertha was always faithful, she only later became insane. Edward highly resents Bertha, and makes it clear. He calls her a hideous demon, a filthy burden, and a maniac,(336, 342, ch. 27) when Jane learns of his secret hiding in the attic. If Iseult resents her marriage to Mark, or Tristan resent his to Iseult of the White hands, they do not make it clear. In their case, they dont feel comtempt for their spouses, only desire for one another ou tside of their marriages. A major difference between the two is the conditions of their love. Tristan and Iseult have no choice. They consumed a potion intended for Iseult and Mark to drink together, without knowledge of its magical implications. They...

The Plays the Thing

The Plays the Thing In Hamlet, there is the line that goes something like The plays the thing wherein we can catch the conscience of the king. If you play your cards right, playwriting can be the thing that earns you some extra money as a freelancer. There is a huge demand for appropriate plays for the middle school and high school markets. The reason is simple. A lot of people have found themselves in a position like I did several years ago when I was directing plays. I just couldnt find something suitable for the resources I had, so I wrote my own. Later, I queried a publisher on the off chance that it might accept freelance submissions. The one I queried did. Brooklyn Publishers accepted one of my plays and asked for more.   Since that first play, I have published seven plays with this company. The one thing about playwriting is that if you establish a reputation as a writer who can deliver what schools need, you can ride that formula to playwriting success. What I wanted was simple enough: easy comedies, simple sets, and flexible casts leaning heavily to more female parts. Now, twice a year I get royalty checks. If you would like to tap into this market, I would make three suggestions: First, look at publisher websites. Brooklyn Publishers is www.brookpub.com. Check out what they publish; read the descriptions and order a couple of plays to read. Do a search for paying magazines that pay for plays. I know of at least two that accept submissions: Dramatics and Plays. Second, go to performances. Im talking high school and college drama performances. Better yet, get involved in community drama. Third, learn some of the ins and outs of playwriting. There are at least two free online playwriting courses you can check on. MIT has an open course ware playwriting course and playwright Johnathan Dorf has on online course called Playwriting 101. You can google these and go right to them. http://ocw.mit.edu/courses/music-and-theater-arts/21m-604-playwriting-1-spring-2005/index.htm playwriting101.com What are you waiting for?

Bone Remodeling Essay Example | Topics and Well Written Essays - 1750 words

Bone Remodeling - Essay Example Bone remodeling is a process of a lifetime in which the old bone is removed by the osteoclasts and replaced by osteoblasts.(9) Parafitt AM., 2002 described the cellular basis of the normal bone remodeling sequence in the human adult to a cycle that constitutes three stages, quiescence, activation, resorption, reversal, formation, and return to quiescence (1). The major reasons of remodeling is to enable the bones to respond and adapt to mechanical stress as occurs as a result of physical exercise and during the mechanical lading as occurs during orthodontic tooth movement. This article outlines the major research carried out in the past decade in the cellular basis of bone remodeling. The aspects included are the relationship between the hormone and localized factors that affect the phenomenon. The dependence of the localized factors and the proteins during the bone resorption is critically discussed. The understanding provided by the RANK/RANKL/OPG paradigm for both the differentiat ion and their activation of the osteoclast is also discussed. Bone undergoes constant bone remodeling and it is a very complex process. In his review article Hill PA., 1998 described four stages involved in bone remodeling, namely, resorptive phase reversal phase, formative phase and resting phase. In the resorptive phase, the activated multinucleated osteoclast derived from bone marrow resorbs a discrete area of mineralized bone matrix. The latter stage than follows in which the osteoblast precursor cells, which can locally proliferate and differentiate into osteoblast migrate into the resorption lacuna and disclose the former osteoclastic activity. The osteoblast deposits new bone matrix which is initially unmineralized and called osteroid and in this way fills the resorption lacuna. This phase is the formative phase. Finally the resting phase is followed. Once embedded in the osteroid, the osteoblast matures into terminally differentiated osteocytes. The osteoblast lying on the surface on the surface of the newly formed bone packet are quie scent lining cells activated.(11) Osteoclast and osteoblast lay the basis of bone remodeling and significant research is been carried out in the past decade. It is known that both osteoblasts and osteoclasts function under the regulation of many factors(3, 7), systemic and local among which insulin, insulin-like growth factors-I, bone-morphogenetic factors and Wnt protins are the potent bone anabolic factors(13). Recently, it was reported that phosphoinosidine-dependent serine-threonine protein kinase Akt plays a major role in signaling of the potent bone anabolic factors. Akt1, a major Akt in osteoclast and osteoblast has a novel role. Akt1 phosphorylates the transcription factor FoxO3a to restrict its nuclear localization, thus suspending the transactivation of its target gene Bim which is also known to be a potent proapoptotic molecule in osteoblasts. This research established that Akt1 plays a crucial regulator of osteoclast and osteoblast by promoting the differentiation and su rvival to maintain bone marrow and turnover.(8) Bone resporption is mainly dependent on a cytokine RANKL (receptor activator of nuclear factor kappa B ligand), which is a TNF (tumor necrosis factor), that is vital for the osteoclast formation, activity and survival

Internation finance Essay Example | Topics and Well Written Essays - 2000 words

Internation finance - Essay Example Owing to the use of foreign exchange in many transactions, businessmen have to hedge their exposures overseas, and to do this they would need to use currencies too to protect their assets or receivables that are denominated in foreign currencies. Others use foreign currencies to engage in speculation abroad, and many mutual funds and hedge funds engage in speculation for possible profit. Thus foreign currencies are necessary to make international trade and investments possible and to help smooth transactions in the tourism industry in many countries. Unlike the stock exchanges, there is no single formal foreign exchange market; it is in fact an over the counter market similar to the one for money market instruments. The main participants are the large multinational commercial banks and investment banking houses. They operate at two levels, the wholesale level where banks operate in the interbank market; and at the retail level, where they deal with individuals and corporations. However, many transactions are mediated by foreign exchange brokers in order to preserve the anonymity of the transacting parties (Kidwell et al 377). The other major participants are the central banks of many countries which may intervene in the market from time to time to modulate the fluctuations of their currencies. Other participants are individuals and non-financial businesses who enter the market for various reasons including speculation. Foreign exchange trading operates without fixed trading hours, round the clock, everyday of the year: When one market closes another elsewhere in the world opens. There are no written rules, and transactions are done according to some principles and code of ethics (Hill 322) There are two basic types of foreign exchange quotations – the spot land forward market. The spot market, with quotations by
