Abstract

Nine serials librarians describe their experiences and offer advice on achieving tenure, promotion, or reappointment. The librarians represent a variety of academic institutions and stages of career, from untenured new librarians to administrators at the rank of full professor. Despite unique insights based on their different experience levels, professional positions, and institutional promotion and tenure requirements, the librarians share common opinions on how best to achieve success in an academic position.  相似文献

The operations management literature on mass customization mainly focuses on the questions of whether and how manufacturers can efficiently deliver customization. Researchers have analyzed the trade‐offs between customization and dimensions of operational performance such as delivery times, quality, and costs. However, we argue that providing efficient customization is not sufficient per se to assess the value of mass customization. From this perspective, this paper focuses on complementary mechanisms for creating value: the benefits perceived by individual consumers. Two global components of perceived value within the context of mass customization are identified: mass‐customized product, with three dimensions, and mass customization experience, with two dimensions. The Consumer‐Perceived Value Tool (CPVT) is proposed to empirically measure the five perceived benefits related to the mass‐customized product and to the codesign process from the consumer viewpoint. The psychometric properties of the CPVT are assessed using three samples. The implications of this approach are discussed, along with directions for further research.  相似文献

Using data from Wave 1 (n = 5,070) and Wave 2 (n = 4,404) of the National Longitudinal Study of Adolescent Health, we examined the relationship between cumulative risk exposure and youth problem behavior. Cross‐sectional analyses revealed a positive, linear association between cumulative risk and problem behaviors. The association between cumulative risk and externalizing problems was stronger for White youth than for Black youth. The association between cumulative risk and internalizing problems was stronger for girls than for boys, and stronger for White youth than for Black and Hispanic youth. Cumulative risk predicted change over time in internalizing problems. Findings support the theoretical notion that adolescents experience diminished psychological comfort when risk factors are present across several social domains.  相似文献

Blest (2000) proposed a new nonparametric measure of correlation between two random variables. His coefficient, which is dissymmetric in its arguments, emphasizes discrepancies observed among the first ranks in the orderings induced by the variables. The authors derive the limiting distribution of Blest's index and suggest symmetric variants whose merits as statistics for testing independence are explored using asymptotic relative efficiency calculations and Monte Carlo simulations.  相似文献

This article studies situations in which information is ambiguous and only part of it can be probabilized. It is shown that the information can be modeled through belief functions if and only if the nonprobabilizable information is subject to the principles of complete ignorance. Next the representability of decisions by belief functions on outcomes is justified by means of a neutrality axiom. The natural weakening of Savage's sure-thing principle to unambiguous events is examined and its implications for decision making are identified.The research of Peter Wakker has been made possible by a fellowship of the Royal Netherlands Academy of Arts and Sciences.  相似文献
