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

Contemporary problems tend to be inherently ‘post‐normal’ in their intimate intermeshing of scientific and contextual concerns. Yet we struggle with this mix, constrained by analytical frameworks that admit one or other of these concerns but not both. While this segregation of material and social domains has been central to the western intellectual tradition, alternative understandings transcending these distinctions have recently been developed. This paper applies some of these insights to risk. Using Actor–Network Theory risk is conceived as a dynamic entity manifested by the relationships between material and social domains rather than as something correlating to either one or other of them. This interpretation illuminates the systemic nature of contemporary problems and the solutions they necessitate underlining, in particular, the significance of matters of scale and complexity. Applied to the risk society it advances insights concerning the pervasiveness of scientific logic and its embodiment by leading institutions, while applied to public participation and HAZOP it emphasizes the benefits of unhindered, intersubjective communication. Harnessing these insights an approach of ‘epistemic pluralism’ is proposed for ‘post‐normal’ problems in which conventional insights and methods are pragmatically combined with those of the form elaborated here. 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

For years economists have ignored the diversity in agriculture and its potential to increase long run growth rates by enhancing a country's knowledge base. Non-traditional agriculture requires significant investments in the infrastructure and knowledge; and therefore, has the potential to increase long run growth rates. Policy makers in developing countries have tended to enact macroeconomic policies designed to enhance the manufacturing sector at the expense of the agricultural sector. A theoretical model is developed to explain the dynamics between two non-traditional export sectors and the long run economic growth of the country. The model illustrates that growth in highly perishable agricultural exports, not domestic production of manufactured goods, can potentially lead to higher long run growth rates. The model is applied to the fruit and flower industries in Colombia to bring forth an example with real world relevance. 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
