Mental disorders that may affect decisionmaking capacity, like schizophrenia, have a deleterious effect not only on persons who are afflicted with the disorders but also on their families, their friends, and their communities. Realizing research to develop generalizable knowledge that may benefit this heterogeneous population is crucial. The moral challenge is to fashion processes that both respect research subjects’ autonomy and protect their wellbeing. Research advance directives may provide a mechanism that authorizes potential research subjects to make choices of their own regarding whether they wish to participate in a research protocol, to choose and appoint a surrogate decision maker, and to secure an array of protections for themselves should they lose their decisionmaking capacity during the period of the research protocol. Such research advance directives may be used by persons with fluctuating, limited or prospective decisionmaking impairments.  相似文献

Hansen P, Ainsworth F. Australian child protection services: A game without end This article argues that Australian child protection services are based on an error of logical typing. Across time, this has led to an over‐reliance on mandatory reporting legislation, a forensic/investigative/prosecutorial model of practice, a risk‐averse organisational culture and zero tolerance of any imperfections in parenting practices which are defined as child abuse and neglect regardless of their severity. All of these positions ignore powerful social stressors that surround complex family situations where abuse and neglect can occur. It is proposed that this error of logical typing is confirmed by the well‐documented fact that Australian child protection services have for more than two decades been unable to prevent or reduce the incidence of child abuse and neglect. For this article, New South Wales is used as the exemplar state.  相似文献

Abstract

In 1999, the California Digital Library (CDL) began a new cooperative venture, the Shared Cataloging Program, to improve access to its growing collection of electronic resources. Now known within the University of California (UC) as the SCP, the Shared Cataloging Program, based at UC San Diego, distributes ready-to-use cataloging records for all electronic titles licensed by the CDL to each of the other eight (soon to be nine) physical UC campuses. The SCP is the result of an intensive systemwide planning process fostered by a desire for an innovative approach to providing traditional bibliographic access to large numbers of electronic resources. It was launched out of pragmatic necessity along with an institutional commitment to the cooperative ideals of labor-savings, experimentation, and the search for “best practices.” This article will describe its genesis, current operation, one library's use of the records, and issues for future development.

The one-box federated search of databases brings as many challenges as promises to database searching, especially in terms of adapting these systems to user needs and the effects this new mode of searching will have on users' research behaviors. This issue of “The Balance Point” presents several librarians with strong interests in reference and instruction, who tell the story of adapting a federated search system for their libraries and reflect upon how federated searching can change the way students do research and on the implications federated searching has on information literacy skills and the quality of results found.  相似文献

The purpose of this article is to investigate hypothesis testing in functional comparative calibration models. Wald type statistics are considered which are asymptotically distributed according to the chi-square distribution. The statistics are based on maximum likelihood, corrected score approach, and method of moment estimators of the model parameters, which are shown to be consistent and asymptotically normally distributed. Results of analytical and simulation studies seem to indicate that the Wald statistics based on the method of moment estimators and the corrected score estimators are, as expected, less efficient than the Wald type statistic based on the maximum likelihood estimators for small n. Wald statistic based on moment estimators are simpler to compute than the other Wald statistics tests and their performance improves significantly as n increases. Comparisons with an alternative F statistics proposed in the literature are also reported.  相似文献

The problem of simultaneously estimating p Gamma means is investigated when the means are believed a priori to satisfy an r-dimensional generalized linear model. Using a Bayesian hierarchical model to reflect the uncertainty in the linear model, approximate methods are proposed to compute the posterior densities. The resulting estimator shrinks the usual estimator toward a prior estimator where the size of the shrinkage depends upon the agreement of the observed data with the proposed generalized linear model.  相似文献

This study examined the looking behavior of married couples during a 10 minute interaction segment. The variables examined included marital adjustment level, interaction role (speaking or listening) and type of message. Wives were more likely to look at their spouses than husbands were, and speakers were more likely to look at their partners than were listeners. While high marital adjustment spouses looked less over all types of mesages, low marital adjustment spouses particularly looked more than the highs on negative messages, suggesting either a confrontation component to the looking, or a strong need to monitor the partner's reactions in such situations. There was also evidence of more displayed competitiveness in the low marital adjustment couples. Correlational analyses revealed that there were different relationships between the looking behavior of the speaking spouse and the looking behavior of the listening spouse, and between the spouses' patterns of looking when speaking or listening and that these differences were dependent on marital adjustment level.  相似文献
