Older adults face many challenges to community living. The literature has not sufficiently explored the roles of care coordination in the maintenance of housing and access to health care among older adults, particularly from their own perspectives. This qualitative study analyzes the findings from 25 interviews and 6 focus group discussions (48 participants) with a multiethnic sample of older adults in the New York City area. Care coordination services appear to assist older adults access health care, and to a lesser extent, maintain affordable housing. Disparities in access to care coordination appear to remain for immigrant, minority and suburban populations.  相似文献

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

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 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

The authors describe the initiation and use of a Web-based triage system in a college health setting. During the first 4 months of implementation, the system recorded 1,290 encounters. More women accessed the system (70%); the average age was 21.8 years. The Web-based triage system advised the majority of students to seek care within 24 hours; however, it recommended self-care management in 22.7% of encounters. Sore throat was the most frequent chief complaint (14.2%). A subset of 59 students received treatment at student health services after requesting an appointment via e-mail. The authors used kappa statistics to compare congruence between chief complaint and 24/7 WebMed classification (kappa = .94), between chief complaint and student health center diagnosis (kappa = .91), and between 24/7 WebMed classification and student health center diagnosis (kappa = .89). Initial evaluation showed high use and good accuracy of Web-based triage. This service provides education and advice to students about their health care concerns.  相似文献

Photography projects are an alternative teaching method that can be easily integrated into community programs with adolescents and children. This article provides a brief review of the use of photography in documenting social and health issues. Two examples of community photography projects with easily ignored populations are described. These projects gave a voice to participants and allowed them to demonstrate their creativity with cameras. An implementation guide is presented to provide concrete suggestions for implementing community photography projects.  相似文献

Research on the prevalence and correlates of dating violence in Mexican teens is challenged by the lack of culturally and linguistically appropriate assessment tools. This study modified, translated, and back-translated the Conflict in Adolescent Dating Relationships Inventory (CADRI; Wolfe et al., 2001) and the Attitudes Towards Dating Violence Scales (Price, Byers, & the Dating Violence Research Team, 1999) for Mexican adolescents. Analyses on 307 adolescents (15-18 years old) from Monterrey and Mexicali, Mexico, revealed that most of the translated CADRI subscales and Attitudes Towards Dating Violence Scales had acceptable internal consistency and test-retest reliability coefficients. The study offers some evidence that the measures may be useful in assessing dating violence in Mexican teens.  相似文献
