Further Reflections on the WorldCat Collection Analysis Tool

This article focuses on a recent enhancement to the WorldCat Collection Analysis tool, the Interlibrary Loan Analyses module, exploring the possibilities that this enhancement offers for strategic collection development. The study concentrates on the tool as a way to assess the impact of the recent growth at North Carolina State University in biomedicine and human medicine programs. The research contained in this article originated from a session presented at XXVII Annual Charleston Conference, which was held in Charleston, South Carolina, on November 8, 2007.

技术系统中概念决策的内在冲突浅析

文章研究产品开发早期阶段中技术解决方案的决策,即概念决策。文章实证研究我国的一家汽车生产企业。研究结果显示,概念决策中一个主要的挑战是在系统解决方案完全成熟之前,产品各系统需要实现兼容。管理者与产品开发人员应当了解,即使缺乏详细的分析,概念解决方案也能发展成为详尽的产品开发方案。在概念决策过程中,一些内在冲突要加以确认。文章认为应提高管理者与产品开发人员对心理偏差的认识。为引导每个人的判断与权衡,大家应对产品及其开发过程具有清楚的认识。     

Severe punishment of children by staff in Romanian placement centers for school-aged children: Effects of child and institutional characteristics

The objective of this study was to determine whether children's characteristics and/or institutional characteristics were predictors of severe punishments (including beatings) and/or frequency of punishments that children received from staff in Romanian institutions. The data was hierarchical with institutionalized children (N = 1391) nested within 44 institutions, and the measurement of punishments by the staff and frequency of punishments had a binary distribution. Thus, multilevel logistic regression models were used to examine the effects of individual and institutional level variables on reported punishments and to account for the clustering of the children within institutions. Two general patterns of results emerged. First, regarding individual level variables, it was found that: (1) amount of time spent by children in their current institutions had a significant effect on the probability of being punished by staff and the frequency of this punishment; (2) the probability of being punished was higher for boys than for girls; and (3) having no siblings in the institution increased the odds of being punished several times. Second, regarding institutional level variables: (4) being in placement centers for school-aged children with a traditional type of institutional organization increased the odds of severe punishment compared to a familial/mixed type. The results of the present study highlight the importance of understanding the consequences of institutionalization in a broader way, where children not only experienced early severe psychosocial deprivation as documented in other studies, but also high levels of severe punishments administered by institutional staff.

Comparison of Female Athlete Triad Coalition and RED-S risk assessment tools

ABSTRACT

The Female Athlete Triad Coalition (Triad Coalition) and Relative Energy Deficiency in Sport (RED-S) consensus statements each include risk assessment tools to guide athlete eligibility decisions. This study examined how these tools categorized the same set of individuals to an overall risk factor score and qualitatively compared athlete eligibility decisions resulting from each tool. Exercising women (n = 166) with complete screening/baseline datasets from multiple previously conducted studies were assessed. Data used for risk assessment included: anthropometric measurements, dual-energy x-ray absorptiometry scans, exercise and health status surveys, and two disordered eating questionnaires (Three Factor Eating Questionnaire and Eating Disorder Inventory). Individuals were scored on each tool and subsequently categorized as either fully cleared, provisionally cleared, or restricted from play. Based on the Triad Coalition tool, 25.3% of subjects were classified as fully cleared, 62.0% as provisionally cleared, and 12.7% as restricted from play. Based on the RED-S tool, 71.7% of subjects were classified as fully cleared, 18.7% as provisionally cleared, and 9.6% as restricted from play. The Triad Coalition and RED-S tools resulted in different clearance decisions (p < 0.001), with the Triad Coalition tool recommending increased surveillance of a greater number of athletes.     

Lexical ambiguity: making a case against spread

We argue for decreasing the use of the word spread when describing the statistical idea of dispersion or variability in introductory statistics courses. In addition, we argue for increasing the use of the word variability as a replacement for spread.
