To achieve sustainability in heritage tourism, tourists should be placed at the heart of the management and planning processes. Indicators and standards-based frameworks were developed in the field of outdoor recreation management to manage and measure crowding and other problematic issues in parks and related areas. Using normative theory and visual research methods, this article aims to examine crowding standards of tourists at Petra Archaeological Park, and compare these standards between the types of heritage tourists suggested by a model developed by Bob McKercher. Results showed that tourists’ acceptability levels go down with an increasing number of tourists, and tourists who are highly motivated to visit heritage sites (i.e. purposeful and sightseeing heritage tourists) had the most restrictive acceptable number of tourists at the park. The normative standards formulated in this article provided a guidance to manage crowding at Petra.  相似文献

The paper provides a bird's-eye view of the long and arduous task of reforming the federal individual income tax. As a starting point for reviewing the major reforms, the authors evaluate Secretary Simon's criteria that underlie his contention that the tax system was badly in need of a thorough overhaul. Principles that should guide tax reforms are spelled out. Conflicts that arise with the application of these principles are highlighted. An examination of reform efforts in light of the principles and criteria set in the Treasury Department's Blue Prints for Tax Reform forms the basis for evaluating reforms enacted over the period 1978–2001. The review suggests that we are partway towards achieving the tax man's dream of equity, efficiency, and simplicity.The task of comprehensive reform is monumental in its dimension and far reaching in itspotential impact on our economic well-being.[William E. Simon, 1977, p. 11]  相似文献

This study examines consumer profile data on waterbed and conventional bed consumers. Five hundred conventional and waterbed consumers in Canada were randomly selected from two national lists of waterbed/mattress purchasers from 1981 to the present. A 73-item questionnaire was sent by mail to all of the selected respondents. The cover letter stated the purpose of the project; to study why people bought the bed that they are presently using. One hundred and sixty-two completed, useable questionnaires were returned, yielding a response rate of 37%. Following a series of multivariate analyses, a consumer profile for the two bed users was developed. Both groups tended to be married. The conventional bed consumers had: (a) either no children or one child at home; (b) a mean age of 44; and, (c) an average income in the $30,000-$40,000 range. Waterbed consumers had: (a) a mean age of 36, (b) one child living at home; and, (c) an average income in the $20,000-$30,000 range. On the Adorno F scale, the conventional bed user was found to be more conservative and authoritarian as compared to the waterbed user. The results did not support the notion that waterbed users are abnormally sexually-oriented or “kinky”. For both groups, the price paid for the purchased bed fell in the $600 to $650 range. Implications for retailers were discussed.  相似文献

The nutritional habits of UK consumers have become a cause for concern with an increasing number of people suffering from diseases related to nutrition. The way in which food is prepared may contribute to the nutritional content of the diet. Traditional methods of cooking and eating are being influenced by increased ownership of domestic appliances. This study aimed to carry out a cross sectional study of people living on Merseyside to determine the ownership and use of small kitchen domestic appliances in relation to the possible consequences the appliances may have on the nutrient intake of the individual. An opportunistic sample of 276 female adults aged 25–70 years was recruited from amongst university staff and community groups within Merseyside. Data were collected using a self‐completion questionnaire consisting of questions concerning personal details, the ownership and use of domestic appliances that may influence nutrient intake. The Liverpool John Moores University Ethics Committee granted ethical approval. Microwave ovens, electric toasters and grills were owned by 80% of the population. Coffee makers, handheld electric food mixers, sandwich makers, blenders and food processors although owned by over 45% were used by the majority only once a week or less. Newer items such as a bread maker were owned by 9% who were significantly more likely to have a professional occupation. Those with unskilled occupations were significantly more likely to own a deep fat fryer and least likely to own a food processor. Those aged 25–34 years were significantly least likely to own a handheld food mixer. Households comprised of couples with or without children were significantly more likely to own sandwich makers, bread makers, food processors and handheld food mixers. No difference in the use of the appliances was found with occupational group or age. A large percentage of people own a variety of domestic appliances, the use of which may have a beneficial effect on their nutrient intake, however, it is of concern that those in the lower socio‐economic group were more likely to own appliances that will have a negative effect on their diet.  相似文献

George DeMartino’s 2011 monograph, The Economist’s Oath: On the Need for and Content of Professional Economic Ethics, provides an excellent basis for the development of a discourse on the ethics of economists. This review focuses on the way in which mainstream economists’ arguments against consideration of ethics follow from their presentation of economics as a purely technical subject, and the implication that this pretense itself is unethical. The complexity of ethical issues within a pluralist approach to economics is explored, ranging from the institutional environment within which economists practice to epistemological questions.  相似文献

Nature-based tourism, science tourism, and ecotourism are some of the emerging and growing trends in special-interest tourism. This study utilized a southeastern sample of the United States who had an interest in travel and the environment. A modified Dillman total design method survey was used to collect the data. The study demonstrated that widely used concepts of marketing are applicable for nature-based tourism. Results indicate that highly involved nature-oriented travelers tend to be more receptive to information concerning the travel product or destination and spread that information willingly. Findings of this study suggest that opinion leaders take more trips and use slightly more information sources.  相似文献

Many American multinational enterprises (MNEs) are currently active in Russia despite the turbulence encountered in that transitional economy. Most seem to have entered as an extension of their global strategies with a long-term horizon. While some entered with considerable involvement and substantial investment, others followed a more cautious or incremental path. This article focuses on how MNE strategies have evolved after entry and describes six strategic approaches. Strategic investment flexibility is found to depend upon a company 's original entry strategy and tolerance for risk, as well as its assessment of the legal and political environment, industry conditions, market readiness for its products or services, competition, and the investment required to establish a sustainable competitive position. Keys to successful strategy development are drawn from the experiences of US MNEs which have established growing businesses in the vast Russian market. The strategies of such successful MNEs, however initiated upon entry, usually evolved to a relatively heavy investment position.  相似文献

An individual's dietary habits are largely developed during childhood and adolescence, and are likely to be determined by both nature (the development of sensory perceptions) and nurture (parental influence, and later on the influence of peers). However, diet is likely to evolve throughout the life cycle as circumstances change and new influences are introduced to an individual's lifestyle. An example of this is the changes in diet that occur as a result of the transition young people make away from the family home into independent living. Leaving behind the meals provided and cooked by parents/guardians and learning how to shop on a budget and prepare and cook for themselves may result in the adoption of poor eating habits, which is likely to have a detrimental effect on health. Leaving behind the restrictions of parental control may also result in the adoption of unhealthy lifestyle practices such as smoking and excessive alcohol consumption. This study therefore seeks to investigate the effect of leaving home on a young person's diet and lifestyle. Health behaviour and food intake was assessed by questionnaire. Findings suggest that a young person's diet may change after leaving home, but these changes are not necessarily negative. More negative health behaviour was observed in young people living independently.  相似文献
