Abstract

The effects of fifteen barriers to participation were examined among people who expressed a desire for but were unable to participate in a new recreational activity. Work commitments, overcrowding of facilities, and lack of partners were the three main barriers. The effects of barriers were not perceived uniformly across the sample but varied between subgroups defined according to socioeconomic variables: the people most likely to be affected by barriers to participation included the poor, the elderly, and single parents. The extent to which recreation practitioners can and should respond to these kinds of research findings is discussed, and several ways in which the effects of barriers to participation might be modified or alleviated are evaluated.  相似文献

Theoretical arguments that leisure is the basis of any culture are available. Yet, scarcity in the literature of serious consideration of leisure in non-Western societies demonstrates that the topic has been neglected. One possible explanation for the failure to achieve progress in cultural comparisons of leisure is the lack of data. At least three approaches permit this type of comparison. This paper focuses on a literary approach by investigating how East Africa's most prominent creative writer, Ngugi wa Thiong'o, treats leisure in his most important English language novels. This analysis centers on two of his novels, A Grain of Wheat and Petals of Blood. The two novels are complex, intricate stories drawing heavily on Western philosophy and literature as well as African folklore. Although Ngugi suggests that leisure is the foundation of civilization, the fibre that makes the cloth of society, he portrays leiusre distinctively in social terms likely to surprise those familiar with Western traditions of leisure.  相似文献

This study investigates the ability of winery tasting rooms to create brand awareness and build long-term brand loyalty. Specifically, we test the conjecture that if tasting rooms create brand awareness and a pleasurable tasting room experience, then those visitors are more likely to recognize and seek out those brands once they leave the tasting room. To measure these effects, we exploit differences in tasting room characteristics to conduct a series of natural experiments from which we analyze differences in off-premise retail sales away from the tasting room. We use scan data on wine sold off-premise through traditional retail outlets to then test for differences among tasting room characteristics. Our results indicate that tasting rooms act as a form of experiential marketing for wineries, creating brand awareness and generating greater growth in off-premise retail sales. Finally, we address issues of endogeneity and unobserved heterogeneity as potential sources of bias.  相似文献

This study is the third phase of a repeated cross-sectional study that explores the current rankings of important accounting skills to lodging managers and the changes in the importance of accounting skills to lodging managers over time. In this study, as with two prior studies, financial executives were asked to rate the importance of a list of managerial accounting skills used by hotel general managers. The top three managerial accounting skills were the operating budget, the income statement, and analysis of variances. This study can provide a better sense of the perception of importance of accounting skills utilized by lodging managers. It will be useful for hospitality educators in designing the curriculum for managerial accounting courses to meet the expectations of the current hospitality industry.  相似文献

Websites have become a channel for tourism enterprises to market and sell their services online. These enterprises are committed to improving their online services to retain customers and improving their competitiveness. This study aims to measure the effect of website quality dimensions on customer purchasing behaviour, and how this behaviour affects customer electronic (e)-loyalty. It compares the perceptions of 275 customers of travel agencies and 355 hotels using structural equation modelling. Findings revealed that website quality dimensions significantly affect the customer purchasing behaviour. The study highlighted the dimensions with a negative effect to help managers improve their website quality.  相似文献

This article is based on a case study carried out at Casa Malva, a shelter for female victims of gender violence in Gijón, Asturias (Spain). The study explores the potential therapeutic value of leisure in the process of personal recovery for women living in sheltered accommodation, and the positive impact leisure may have in overcoming a traumatic life event. The study comprised 16 semi-structured interviews with female victims of gender violence and three discussion groups with shelter staff. The article examines the concept of leisure and the potential benefits of leisure activities as part of the Personal Recovery Project (PRP) run by Casa Malva. PRP is an innovative recovery initiative aimed at helping women to overcome situations of gender violence by focusing on areas of experience, such as family, employment and leisure.  相似文献

The purpose of this study was to explore the relationship between mandatory food safety training and certification and inspection results of chain restaurants and independent restaurants, using current food safety inspection results of food service establishments in Central Florida. More specifically, this study examines whether there is any statistically significant difference in the violation frequency among chain and independent restaurants. Reducing the risk of any foodborne illness is a critical strategy that industry stakeholders should pursue in an area dominated by tourism such as Orlando, Florida. A one-way ANOVA was used to determine the differences between the two types of restaurants. Findings indicate that there is significant difference between chain and independent restaurants for critical violations. No difference was found when comparing chain verses independent restaurants for non-critical violations.  相似文献

Federal lab commercialization is explored: (1) by analyzing US government patents and (2) in a qualitative analysis of one NASA lab's patents. Tests apply to three distinct sets of patents, 1963–94: NASA, all other US government, and a random sample of all US inventors' patents. The federal patenting rate plummeted in the 1970s. Consistent with increasing commercialization, both NASA's and other federal agencies' rates recovered in the 1980s. The case study finds citations to be a valid but noisy measure of technology spillovers. Excluding 'spurious' cites, two-thirds of cites to patents of NASA-Lewis' Electro-Physics Branch were evaluated as involving spillovers.  相似文献
