Implementation of a Federated Search System: Resource Accessibility Issues

Abstract

During 2009, the Hilton M. Briggs Library, South Dakota State University, went live with MetaLib, a federated search engine from Ex Libris. This paper presents the implementation process, addresses resource accessibility issues, and suggests a number of resources that can be consulted about these issues. Readers can apply similar strategies to projects involving federated search systems, as many implementation projects involve the same basic considerations presented here. The author did not find any studies specifically focused on configurations of MetaLib resources, so this content should be singularly useful.     

对应分析统计检验体系探讨

对应分析因其结果的易读性，近些年得到了越来越广泛的应用。为了更好地应用对应分析，提出建立对应分析统计检验体系，包括对应分析适用性的统计检验以及对应分析效果的检验，同时还提出应用对应分析时应注意的其它问题。     

On the asymptotic distribution of cramer-von mises one-sample test statistics under an alternative

The asymptotic normality of the Cramer-von Mises one-sample test statistic and one of its variants under an alternative cdf is demonstrated. The derivation herein is unique in that it does not require knowledge of the theory of weak convergence of probability measures defined on metrized function spaces, and thus is accessible to a broader class of students and practitioners.     

Estimability and Linear Hypotheses

A proposition is given which provides an easily justified reason as to why attention should be confined to estimable parametric vectors when formulating linear hypotheses. The possibility of justifying one's linear estimation effort on the estimable parametric functions via an identifiability condition is also mentioned.     

如何发现DNA是生命的遗传物质

从核酸的发现到DNA双螺旋结构模型建立历时80余年,人类最终确认了DNA是生命的遗传物质,解决了一个生命科学研究中极其关键的重大问题。因此,对此段历史的研究具有重要意义。全面回顾此间发生的对揭示DNA的结构和功能具有重要影响的事件,包括米歇尔发现核酸、列文提出＂四核苷酸假说＂、格里菲斯等人的转化实验、査伽夫提出碱基配对规律,以及沃森和克里克建立DNA双螺旋结构模型,在此基础上阐述人类发现DNA是遗传物质的研究历程,进而探讨科学研究的规律。     

Grandmothers', Mothers' and Granddaughters' Perceptions of Grandparenthood

ABSTRACT

The aim of the present study was to assess the meaning of grandparenthood in grandparent-parent-grandchild triads, and to examine its congruence between generations.

Three types of relations were found: (1) the congruent-strongly connected relationship, characterized by a reciprocal and nurturing relation; (2) the congruentnon-connected relationship, characterized by an agreement among all members regarding the problematic and dissociated relations; (3) the non-congruent relationship, characterized by a lack of agreement regarding the nature of the relation.

管仲改革与梭伦改革之不同历史价值

管仲与棱伦分别是先秦齐国和古希腊城邦影响最大的政治家,也是中西政治思想史、化史上的重要人物。在二的改革与实践中,都蕴涵着极其丰富的历史价值。但是,由于管仲采取“法自君出”政策,强调君主专制制度;梭伦采取“主权在民”,建立民主制度;加之二改革所依托的社会载体不同,致使二的改革在民主思想观念等方面形成极大差异,也直接影响中西民主思想的历史进程。     

Is there a relationship between burnout and objective performance? A critical review of 16 studies

Previous research has suggested that high levels of burnout lead to impaired functioning on the job. However, as this research has usually relied on self-reported performance, it is imperative to examine whether this association is also confirmed when using “objective” performance data (e.g., supervisor reports). This study reviewed previous research on the associations between burnout (exhaustion, depersonalization, and personal accomplishment) and various types of objective performance. A systematic literature search identified 16 studies dealing with the burnout-performance relationship. These studies showed the wide variety of approaches that are used to study burnout and objective performance. Using data from these 16 studies, a meta-analysis was conducted to obtain mean correlations. The meta-analytical correlations between exhaustion and in-role behaviour (based on five studies), organizational citizenship behaviour (OCB; five studies), and customer satisfaction (two studies) were -.22, -.19, and -.55, respectively, underlining the practical relevance of burnout research for organizational performance. The evidence for the relationships between depersonalization, personal accomplishment, and performance was inconclusive. Future research should focus on valid indicators of job performance, should more often employ longitudinal designs and large samples, and should consider the theoretical basis for the study expectations more extensively.
