Measuring Women's Quality of Life: A Discussion of Alternative Approaches

This paper reports our experiences with the application of a number of alternative approaches to a study of women's economic circumstances and quality of life in a typical western city. The important work of, especially, Martha Nussbaum on the capabilities approach to evaluations of “quality of life” has highlighted pitfalls associated with the use of a narrow informational base in studies of women's lives and has emphasized the value of qualitative methods in these evaluations. However, to date, most discussions of the relevance of plural approaches to studies of women's lives have been conducted in the context of developing countries. This paper contributes a practical, current example of the relevance of such approaches to assessments of the lives of women in western countries as well. The research findings reported in the paper also cast further light on the importance of several, related themes in the literature on the capabilities approach, namely the importance of understanding how women's aspirations and expectations change with their economic and social experiences; and the importance of appreciating the social uses of language and how this affects the way in which women describe their lives.     

The business model and balanced scorecard in creative tourism: the ultimate strategy boosters

Despite the various studies on creative tourism, little managerial frameworks such as a business model and a balanced scorecard are investigated for this new phenomenon. The overall image that emerges from the literature is ambiguous and fuzzy. Also, many activities known as creative tourism experiences may provide new participative experiences but rarely include a creative process. This study covers a whole aspect in designing a feasibility test model for creative experiences based on balanced scorecard through qualitative content analysis and as the essence of that, a Business Model by content validity and clustering analysis. Analysis of data by the mentioned methods reveals that four perspectives and 13 critical success factors are essential for the feasibility of a creative tourism experience. In addition, 22 indicators in 3 main dimensions determine the success of a creative tourism business model. This study is part of a growing body of research focused on discovering hidden aspects of creative tourism.     

The complexity of food choices in an everyday context

This study aims to understand the complexity of food choices in an everyday household context. The qualitative data are based on homemakers’ (n = 18) context‐specific accounts of their choice of milk brand, i.e. milk varieties with different fat contents (noted in a 4‐day qualitative food diary and a semi‐structured interview based on the diary). These accounts were considered an approximation of real food choices in households. The necessity of making compromises between contradictory expectations makes food choices, as well as milk brand choices, problematic. The homemakers' accounts involve various levels affecting household activities. At the individual level, the most important motive of choice is the taste and practical use of a product. At the level of households, the traditions stemming from one's childhood and the social aspect of acknowledging other family members’ taste preferences are important. The influence at the level of society and culture leads towards healthier choices, e.g. by providing examples of new, healthier food habits. Here, the special nature of everyday knowledge is emphasized as context dependent. This provides a complementary view to the more traditional, cognitive views of studying the relationship between knowledge of nutrition and food choices. Choices are determined not only by stimulus, cognition or societal structures, but are also constrained by everyday conditions, as well as by the activities of other people.     

用层次分析法构造信托公司定性评价模型

定性因素的权重难以通过纯计量方法得出。由于层次分析法可以避免专家判断的不一致性，可以用这种方法来解析专家问卷并得出定性权重。在商业银行构造信托公司内部信用评级的定性评价模型时，首先是确定信托公司定性评价指标框架，接着根据指标框架设计并发放调查问卷，然后再根据问卷调查结果得出各层评价目标的判断矩阵，从而求出各定性因素的权重向量，最后综合各层次权重就可以得出各定性因素在整个定性评价体系中的权重分配。     

Outdoor recreation expenditures and the effects of spatial structure

Abstract

Visitor expenditure models have been the focus of substantial attention in outdoor recreation research because of their significance in estimating local economic impacts. At the disaggregate level models have usually included simple measures of distance decay and variables representing the attributes of households and supply features. Scholars have ignored the differential effects that the spatial structure of opportunities might have upon expenditures. This paper presents an analysis of the effects of spatial structure upon visitor expenditures for outdoor recreation in Oklahoma. Analyses are presented which identify and differentiate the relative effects of spatial structure upon visitor expenditures and the alternative forms of spatial diversification behavior consistent with such expenditure patterns.     

Understanding resident subjectivities toward tourism using Q method: Orchid Island,Taiwan

The pursuit of sustainable destination tourism should begin with an understanding of resident subjectivities. Residents are concerned with good governance and cultural integrity, and they are aware of their role as stakeholders in tourism in their communities. In this study, residents of Orchid Island, Taiwan, were interviewed using Q method in order to evaluate their subjectivities toward tourism. Forty-two statements regarding a theoretically and historically defined discourse of tourism were sorted by 34 respondents. This forced-choice method revealed four types of subjectivities, which are distinguished as Culture Broker, Cultural Conservative, Cultural Purist and Pragmatic Governance. The results show how the respondents perceived tourism in their destination. They agreed upon certain core issues regarding destination tourism, while contesting other issues. Respondents held strong views concerning how government policy affects their community and how tourism and culture shape each other. It is concluded that many issues in tourism research are highly relevant to residents of small tourism destination communities. This implies that tourism research should focus on understanding and coordinating resident subjectivities so as to inform government planning and decision-making, especially in indigenous communities or small islands.
