Daily diaries are a widely used measurement tool in studies on the use of social time. However, while their high level of accuracy is supported by a lot of research, scholars often voice doubts regarding the validity of the estimates obtained if the characteristic rhythm of the events in question is not completed within a 24-h period. This study attempts to explain why, although these statistics are not wrong, they need to be understood correctly before proceeding with research based on them. To overcome the problem we will propose a solution for new surveys where use of diaries of this type is scheduled. Although this solution is not without limitations, they are much less restrictive than those imposed by traditional daily diaries.  相似文献

The paper investigates cross-country differences in wage mobility in Europe using the European Community Household Panel. We examine the impact of specific wage-setting institutions, such as the collective bargaining and the trade union density, the employment protection regulation and the welfare state regime on wage mobility. We apply a log-linear approach that is very much similar to a restricted multinomial logit model and much more flexible than the standard probit approach that is typically applied in the research on wage mobility. It is shown that the macro-economic context and the aforementioned specific institutions explain a substantial part of the cross-country variation that is larger than the part that regime type explains. The findings also confirm the existence of an inverse U-shape pattern of wage mobility, showing a great deal of low-wage and high-wage persistence in all countries.  相似文献

In this paper a fuzzy quality function deployment to identify service management requirements for customer quality needs is developed. First, customer quality needs with importance degree have been investigated followed by development of service management requirements for satisfying the observed customer quality needs. Furthermore, construct a fuzzy relation matrix to link service management requirements and customer quality needs based on cross-functional expertise. The aggregated fuzzy assessments of various service management requirements are ranked to determine their importance priority. Finally, an empirical study for identifying the service management requirements for customer quality is used to demonstrate the proposed approach.  相似文献

Our study investigated the follower perceptions of leader–member exchange (FPLMX) as a mediator between leader political skill (LPS) and follower morale and tested these relationships using data obtained from casino dealers in Korea. Social astuteness, interpersonal influence, networking ability, and apparent sincerity are the indicators of LPS, while follower morale is composed of job satisfaction and affective organizational commitment. The results from structural equation modeling suggest that the research model we have proposed is viable. Broadly speaking, FPLMX is a partial mediator between LPS and follower morale.  相似文献

We study the economic and non-economic sources of stock return comovements of the emerging Indian equity market and the developed equity markets of the US, UK, Germany, France, Canada and Japan. Our findings show that the probability of extreme comovements in the economic contraction regime is relatively higher than in the economic expansion regime. We show that international interest rates, inflation uncertainty and dividend yields are the main drivers of the asymmetric return comovements. Findings reported in the paper imply that the impact of interest rates and inflation on return comovements could be used for anticipating financial contagion and/or spillover effects. This is particularly critical since during extreme market conditions, the tail return comovements can potentially reveal critical information for active portfolio management.  相似文献

This study investigates how the ex-ante threat of termination affects firm performance in innovation measured by number of patents and citations. Empirical results show that the threat of termination is negatively associated with both measures of firm innovation. This relation however is sensitive to industry structure. The negative effect of the threat of termination on innovation is statistically significant only for high-tech firms. For low-tech firms there is no statistically significant relation between the threat of termination and firm innovation. One plausible explanation is that high-tech firms are inherently risky and have higher rates of project failure. Adding the risk of higher threat of termination makes the manager more risk averse and forces her to avoid investing in value increasing innovations. Managers in low-tech firms don’t face such pressures. The policy implication is that high-tech firms should lower threat of termination and increase tolerance for project failure to encourage innovation.  相似文献

Abstract

This article examines the cultural field of fitness as a network of producers, consumers, products and practices that has developed around the care of the body through physical exercise. Drawing on a thematic text analysis of US exercise manuals, the paper focuses on how the commercial fitness field naturalizes associations between physical exercise and leisure, and between leisure and self‐work. In particular, the analysis examines three themes and their relevance to our broader understanding of leisure in contemporary consumer society: the management of leisure time; the use of leisure for self‐investment strategies; and the promotion of consumption as the framework for leisure and an accompanying notion of pleasure. The fitness field casts light on how leisure more generally is constructed as a sphere of obligations to make productive use of one’s time, to improve one’s body and self, and to do so through the wares of the consumer marketplace. The cultural imaginary of leisure as a time of freedom from work and responsibility is thus recast, in an age of individualization, as a time of freedom to accomplish the work of self‐production.  相似文献
