The Pacific Rim Library (PRL) is an initiative of the Pacific Rim Digital Library Association (PRDLA). The project began in 2006 using the OAI-PMH paradigm and now holds over 300,000 records harvested from OAI data provider libraries around the Pacific. PRL's goal is to enable the sharing of digital collections amongst PRDLA members and the world, but greater unexpected benefits have been discovered. Through mirroring their metadata, PRL increases the chance that their data will be discovered in Google and other general search engines. With its many disparate collections, PRL is not a repository for traditional information discovery and retrieval. Initially users will bounce from a Google hit to the PRL metadata record in Hong Kong and then begin an intensive search on the original site which hosts the full digital object, in Vancouver, Honolulu, Wuhan, Singapore, or other PRDLA member location. 相似文献

This paper experimentally investigates how risk attitudes mitigate leadership effectiveness in a collective setting with projects that exhibit both free riding and coordination problems. We take two novel approaches: 1) the introduction of economic game theory to psychological studies of leadership, and 2) the application of the leadership ontology of Drath et al. (2008) as a cross-disciplinary integrative framework. Leadership here is focused on the presence or absence of direction, alignment, and commitment as well as antecedent beliefs and practices that are held within a collective (for us, our experimental participants). Our leadership context is stripped down to very minimal conditions: three group members, an investment decision, and the introduction of information regarding group members' attitudes toward risk. We find that the mere mention of risk attitude (whether risky or risk averse) undermines leadership effectiveness in mitigating free riding for our 420 experimental participants. Our study's primary implications lie in the application of game theory methodology to the psychological study of leadership, the introduction of relevant individual difference constructs to economic studies of leadership, and the advocation of the Drath et al. (2008) framework as a helpful integrative mechanism for interdisciplinary leadership research. 相似文献

Abstract Forced terminations typically are described in the therapy literature as grim mourning processes fraught with peril and little benefit. Such endings, although not optimal, are potential opportunities for mastery, growth, and maturation. Overemphasizing the grim aspects of forced termination may impair the departing therapist's ability to sustain a belief in the client's ability to survive loss, use the process productively and, when indicated, transfer to another therapist. Case histories are used to illustrate other constructions and differential interventions during forced terminations. 相似文献

Gart (1972) ottered a Statistic on testing the hypothesis of no second-order interaction in a 2×s×t contingency table. The statistic was tn be used as an asymptotic chi-square with (s-1) (t-1) degrees of freedom. We show that this statistic suiters from the drawback that unless certain side conditions hold, the statistic would reject the null hypothesis with probability approaching one asymptotically even in the null case. Hence the statistic is not strictly valid for the hypothesis for which it was intended. 相似文献

英语里的词义关系是传统语义学家最为关注的语言现象之一,反义关系作为词义关系的一种,常被理解成一种静态的,固定的对立、相反或互补关系。本文章以D.A.Cruse提出来的动态语义识解论为理论依据,将英语里的反义现象识解成一种动态的语义建构,认为词义的相反、相对或是互补关系是一种依赖于语境的语义关系,从而希望借此文引发认知语义学研究者对于英语反义现象新的思考。 相似文献

Abstract Though the impact of managed care on clinical social work practice and education has been widely acknowledged and critiqued, Humane Managed Care? edited by Schamess and Lightburn, represents a compendium of papers addressing all aspects of the recent phenomena and its impact on practitioners, educators, and most especially our clients. In reviewing this impressive and comprehensive volume, this paper addresses many of the most controversial and painful aspects of the “Managed Care Revolution,” including its impact on the level of clinical practice and its economic and political ramifications. It is suggested that the editors and some of the authors are less hopeful about the possibility of providing “humane” treatment in the managed care environment than they were only a few years earlier, as indicated by a comparison of this volume with the 1996 special edition of Smith College Studies in Social Work. This article also critiques some of the anthology's chapters, which suggest that the changes in health care delivery will ultimately be beneficial to clinical social workers.

We establish the exact expressions of X1/X2 and of X1/(X1+X2), where X1 and X2 are independent beta random variables of the first type, and provide some of their applications, in reliability and availability. 相似文献

Almost all studies of same-sex parenting have concluded there is “no difference” in a range of outcome measures for children who live in a household with same-sex parents compared to children living with married opposite-sex parents. Recently, some work based on the US census has suggested otherwise, but those studies have considerable drawbacks. Here, a 20 % sample of the 2006 Canada census is used to identify self-reported children living with same-sex parents, and to examine the association of household type with children’s high school graduation rates. This large random sample allows for control of parental marital status, distinguishes between gay and lesbian families, and is large enough to evaluate differences in gender between parents and children. Children living with gay and lesbian families in 2006 were about 65 % as likely to graduate compared to children living in opposite sex marriage families. Daughters of same-sex parents do considerably worse than sons. 相似文献

In this paper further asymptotic expansions of the non-null distribution of the likelihood ratio criterion for testing the equality of several one parameter exponential distributions are obtained when the alternatives are close to the hypothesis. These expansions are obtained for the first time in terms of beta distributions. 相似文献

A new class of statistical tests for uniformity based on sample ranges is proposed to detect a uniform density contaminated by a density with one or more high peaks. These kinds of alternatives occur quite frequently, especially in physics. It is shown that the proposed tests arc consistent and have high Pitman asymptotic relative efficiencies. Results of a Monte Carlo power study indicate that they, compared with other tests of uniformity, possess good power properties.A comparative study of various tests is also conducted using real data. An effcient algorithm for computing out test statistic and a table of percentage points are given, providing a practical guide for using the new test. 相似文献
