Two facets of leisure, perceived determinants of well-being and enjoyment of common leisure activities, were investigated in 388 participants. For well-being, a principal components (PCA) analysis yielded five components: competence, relatedness and health, wealth, personal values, and freedom of choice. For the enjoyment of leisure activities, another PCA generated seven components: wellness, sedentary leisure, intellectual leisure, social leisure, routine activities, self-realization, and inner peace. Different leisure enjoyment of young adults (18–30 years old) in contrast to adults and seniors was attributed to social transformations as also predicted by several theories of social change. The relationship between the determinants of well-being and enjoyment of leisure activities was statistically significant but meaningfully debatable. 相似文献

Contrasting their work with that of Christopher Ross Bell, the authors present a graphical isoquant analysis that suggests that it is not possible for a production function characterized by decreasing returns to yield economies of scale. 相似文献

Child care and housing programs in the United States are markedby quality homogeneity, restricted eligibility, rationing, andcopayments that increase as recipients' income rises. Why? Ishow that these programs can best be explained as attempts toreduce the child care or housing 'poverty gaps,' subject toconstraints that require that recipients be treated quite well.Such constraints are justified when the public is really notsure whether the government is acting generously. 相似文献

Using quarterly data for 1972–2000, the paper examines the long-term and short-term movements of the US-Canadian exchange rate. It is found that the standard purchasing power parity condition fails to explain movements of the Canadian dollar. The explanatory power of the model increases significantly when resource commodity prices are added to the equation. Short-term movements in the Canadian dollar are influenced by the interest rate differential between Canada and the USA. 相似文献

Communication is fundamental to team work and it occurs increasingly often in a technology-mediated environment. Understanding how communication evolves in such environments is essential to ensuring that the right technology is provided for whatever task a group needs to accomplish, even if it is not precisely known how the technology is going to be used. With the growing body of research on different tools for supporting computer-mediated groups, we still have much to learn about how communication evolves, where potential breakdowns occur, and how groups tailor technology during the communication process. This paper addresses these important issues by providing an in-depth analysis of two-person dyads that communicated over a web-based set of collaboration tools during a 6-week project. We analyze communication through the lens of communicative action theory, showing how social action unfolds during communication and how groups challenge and resolve validity claims in different task-technology environments. This study contributes by exploring group processes, developing and applying group communication analysis tools, and enhancing theorizing on technology tailoring. 相似文献

We review three alternative approaches to modelling survey non‐contact and refusal: multinomial, sequential, and sample selection (bivariate probit) models. We then propose a multilevel extension of the sample selection model to allow for both interviewer effects and dependency between non‐contact and refusal rates at the household and interviewer level. All methods are applied and compared in an analysis of household non‐response in the United Kingdom, using a data set with unusually rich information on both respondents and non‐respondents from six major surveys. After controlling for household characteristics, there is little evidence of residual correlation between the unobserved characteristics affecting non‐contact and refusal propensities at either the household or the interviewer level. We also find that the estimated coefficients of the multinomial and sequential models are surprisingly similar, which further investigation via a simulation study suggests is due to non‐contact and refusal having largely different predictors. 相似文献

The Indonesian dairy industry has been viewed by the Indonesian government as an industry that has the potential to improve the welfare of low income and landless farmers through providing them with an additional source of farm income. As well, the government sees the industry as a vehicle for providing opportunities for employment in rural areas. From an economy wide viewpoint, its development is viewed as a way Indonesia might save foreign exchange since a large share of its dairy requirements have to be imported. A variety of measures have been used to assist the industry. This paper investigates one of the measures, the BUSEP scheme or mixing ratio regulation which requires domestic processors to use Indonesian produced milk before imported milk. 相似文献
