The change from the z of “Student's” 1908 paper to the t of present day statistical theory and practice is traced and documented. It is shown that the change was brought about by the extension of “Student's” approach, by R.A. Fisher, to a broader class of problems, in response to a direct appeal from “Student” for a solution to one of these problems. 相似文献

AbstractTo increase the effectiveness and efficiency of searches for information, accounting students, researchers, practitioners, and regulators could benefit from a Website devoted to the electronic access to journals. The site described here addresses such a need in the business discipline of accounting. On the site, the titles of over 470 journals are listed and categorized by topical areas within accounting. Then, within each accounting category, the journals are grouped according to their Internet accessibility. To provide the user with quick access to the various journals, the site provides links to the homepages of the various journals. Serials Review 2002; 28:201–205. 相似文献

Objective. Research on widespread loan failures suggests that many of the mortgage loans that were made since 2000 were of a deceptive or predatory nature. This study explores the experiences and sentiments of those who are at risk of foreclosure within a broader framework of trust, individualization, and ontological security. Methods. Interviews examine families' lending experience and how they have coped with their personal troubles that resulted from their housing crisis. Results. As many of these loans were of a deceptive or predatory nature, individuals are likely to reflect on the psychological consequences of their predicament. Although these findings suggest that these individuals have lost trust in the housing market, many have internalized their situation as a personal failure. In addition, feelings of anxiety, stress, insecurity, and uncertainty have come to characterize their experiences. Conclusions. This research calls for policy recommendations that seek to restore confidence and to ensure greater consumer protection in financial markets. 相似文献

All that is known about strategy and strategic planning indicates that quality is a major factor in gaining competitive advantage. It is cost effective, profitable, promotes corporate longevity and builds an important company value system. The authors argue that is too important a factor to be left solely to quality control personnel or planners and is a fundamental part of the chief executive's responsibility for the development of strategy. 相似文献

This articleconcerns nonparametric estimation of association between bivariatefailure times. In the presence of independent right censoring,the support for failure time variates may be restricted and measuresof dependence over a finite failure time region may be of particularinterest. To this end, the reciprocal cross ratio function, weightedby the bivariate failure time density, is proposed as a summarymeasure of dependence over a failure time region. This `relativerisk' estimator is shown to be consistent and asymptoticallynormally distributed, with consistent bootstrap variance estimator.A finite-region version of Kendall's tau, which is suitable forcensored failure time data, is also proposed, and correspondingasymptotic distribution theory is noted. The accuracy of theseasymptotic approximations is studied in simulations and an illustrationis provided. 相似文献

Performing some laboratory tests on site at a student health service clinic may increase efficiency and cut costs for patients. However, with the passage of the Clinical Laboratory Improvement Amendments (CLIA) of 1988, many laboratories in physician offices and clinics have shut down because of increased regulatory requirements. The personnel in one SHS laboratory found that the guidelines proposed by CLIA help assure quality care and are not prohibitive. In this article, the process of applying for and receiving a CLIA certificate in the student health clinic setting is explored. 相似文献

One of the most prominent interventions developed to protect victims in domestic abuse cases is the temporary restraining order or "TRO," the purpose of which is to restrain an alleged defendant from further harassment or abuse against a plaintiff. This report analyzes 397 restraining order petitions, and subsequent arrest and conviction data for TRO defendants from 1996 to 1998. Findings confirm that TRO petitioners report many types of abuse and while half of TRO defendants do not re-offend, a small percent of defendants are responsible for multiple police reports, arrests, and criminal violations. Outcome data are discussed for program and policy implications. 相似文献

Effective targeted and community HIV/STD prevention programs 总被引:1,自引:0,他引:1
Community interventions and interventions targeting specific groups at risk of STDs/HIV have demonstrated significant impacts on sexual behavior, particularly condom use and safer sex. The scientific evidence suggests the factors that make these interventions particularly effective include the establishment of community, including business and CBO partnerships; maintainance of the intervention post-research funding; and buy-in by the community or target group. The modification of risky normative beliefs through the use of opinion leaders and role models, and through intervention delivery by peer educators, is an important facet of such interventions. Interventions delivered by health professionals, absent a community base, appear to be unsuccessful. Where cultures or subcultures are targeted, the close involvement of such groups in the design and delivery of messages is critical to their success. Diffusion of interventions through existing social networks further extends the intervention into the community and acts to reinforce and maintain changes in peer norms toward safer sexual behavior. The available data confirm that community or medical infrastructure-based interventions are effective in changing sexual behavior and can reach a wider range of the population than face-to-face programs if they incorporate peer educators as role models in modifying norms, and if diffusion of the intervention is integral to the design. 相似文献

Gaps in service coordination between child welfare and other child-serving agencies are well documented. This article examines the gap between the child welfare and juvenile justice systems and discusses a program, Project Confirm, designed to reduce the problems associated with this gap. Project Confirm aims to improve cooperation between juvenile justice and child welfare agencies to prevent the unnecessary detention of arrested foster children in secure facilities. The program's design is outlined, and implementation statistics and government partner perceptions of the program in its first year of operations are provided. The article also identifies future challenges to implementation and discusses the broader implications of the program. In making this appeal for coordination and collaboration among public agencies, I'm not talking about pro forma integration efforts-I'm not talking about memoranda of understanding or top-level reorganizations that have autonomous agencies vaguely reporting to a single box labeled "human services." Rather, I'm talking about the much more challenging objective of achieving real working partnerships at the front line. (Nelson, 1998, p. 6) 相似文献
