The histograms of interpurchase times for frequently purchased packaged goods have consistently shown pronounced seven-day cycles. Evidence supports that the weekly spike phenomenon is the result of consumers' regular shopping trip schedules. We explore the implications of this peculiar regularity on the issue of consumer purchase timing acceleration. Data for five product categories are examined. Promotions are found to have little effect in accelerating purchase timing. In contrast, conventional interpurchase time models are shown to overstate the effect of promotions. 相似文献
This study examined the longitudinal associations of emotional regulation and school readiness among Chinese kindergarten children. Data were collected from 523 children (mean age at time 1 = 52.42 months; 52.9% male) at two time points separated by approximately 1 year in Hong Kong, China. At times 1 and 2, children's school readiness was assessed by their teachers and parents while their emotional regulation was directly tested. Teachers also rated children's emotional regulation at both time points. The results from the two reciprocal path models showed that, controlling for the corresponding autoregressive effects, school readiness at time 1 was predictive of emotional regulation at time 2. However, emotional regulation at time 1 did not emerge as a significant predictor of school readiness at time 2. Theoretically, these results underscored children's school readiness as a potential contributor to their emotional regulation. Practically, these findings suggested the utility of supporting children's school readiness to foster their emotional regulation. 相似文献
Based on the decision-making process that actually happens in most organizations, a management support system (MSS) or an integrated decision support systems (DSS) is defined as a network of subsystem interfaces, as opposed to management information system (MIS) being a network of information flows. Three modes for subsystem interfaces are discussed. To help the operationalization of the (computerized) support system, we also propose a design architecture which consists of the continuum of conceptual constructs, operational constructs and implementational constructs. 相似文献
Abstract The objective of this investigation is to elaborate and test the linear development and systemic models of community attachment. We focus on the interplay of community size, five social position variables, and three dimensions of community attachment, namely, involvement, amity, and sentiment. Data are obtained from a statewide migration telephone survey of 851 respondents aged 18 and over, conducted in Utah in October 1988. We focus on a weighted subsample of 415 nonmetropolitan respondents. Multiple Classification Analysis (MCA) techniques are employed. Contrary to the linear development model, community size did not have an independent inverse impact on community involvement, amity, and sentiment. Results do vary by social position and community attachment dimensions. 相似文献
Western culture, and therefore Western management methods and thinking, has devalued other cultures, and it has been assumed that the high culture of dominant nations has taken over. But this is not so; cultures of everyday life are complex and not easily destroyed. They are also systems in motion, that can adapt easily.Tzöl Zae Chung explains the striking differences between Asian and European thinking and ways of managing and doing business. Misunderstandings can occur if two cultures meet without adequate prior preparation. But increasingly, Japanese management methods are revitalizing Asian values and attracting attention. The cultural factor in globalization — especially in the ‘triad’ of trade between the US, the Asian-Pacific region and Europe is becoming critically important. 相似文献
ABSTRACTEthnicity is a social construct that can be conceptualised as a social classification delineating certain boundaries between an ethnic group and the dominant group. Members of an ethnic group are assumed to share similar cultural characteristics and to be homogenous among themselves. Many studies in ethnic organisations have indicated that subethnicity also exists within an ethnic group, but research on subethnicity is scant. Based on the findings of an exploratory study conducted in Vancouver, Canada, we examined how, at an interpersonal level, place of origin, language, mutual bias and discrimination and transnational politics divide the Chinese diasporic community subethnically. Meanwhile, being Chinese in the Canadian context and willingness to break the subethnic boundaries are noted as counterforces to the subethnic divide. We contend that interpersonal interaction is an imperative dimension for the understanding of the shaping of boundary between different subethnic groups. 相似文献

In this study, we suggest a new perspective on the linkage between alliance portfolio diversity and innovation performance based on a contingency approach. Using a longitudinal data set on alliance portfolios and patents of 182 firms in the U.S. manufacturing industries, we examined that alliance portfolio diversity has a U-shaped relationship with firm-level innovation. Internal value creation capabilities in terms of routine and ability are found to moderate the relationship between alliance portfolio diversity and innovation performance: organizational search routine strengthens the relationship of alliance portfolio diversity and innovation performance while technological capabilities weaken and flip the relationship.
