This paper outlines the principles underlying the Australian AIDS strategy and offers an explanation for its success in reducing the spread of the human immunodeficiency virus (HIV) among homosexual and bisexual men in Australia's gay communities. A brief outline of the AIDS education activities offered by the gay-community AIDS organisations is followed by results from the Social Aspects of the Prevention of AIDS (SAPA) research project based at Macquarie University. This research confirms the importance of the community-intervention strategies utilised by gay AIDS organisations. The paper then assesses progress in the development of community-attachment strategies for men who have sex with men but who are not attached to organised gay communities. 相似文献

Abuse of children and adolescents is a societal problem. If health-care providers are to intervene adequately in abuse, they must identify the occurrence, elicit all pertinent information surrounding the abuse and the patient's response, and integrate pertinent abuse issues in the overall treatment plan for the patient. This study has conclusively demonstrated the failure of health-care providers to assess and plan treatment based on the comprehensive documentation of sexual and physical abuse factors. Findings clearly indicate a need for education of health-care providers in the development of comprehensive and integrated treatment plans for abused psychiatric patients based on documentation of all factors related to trauma learning and replay. Service agencies must be willing to implement in-service programs that provide nurses and other health-care providers with the cognitive and affective knowledge and skills necessary to feel comfortable in the management of abuse issues. 相似文献

We employ a discretetime hazard model and a Blinder-decomposition approach to explore the possibility of racial discrimination
in the dismissal and retention of college football coaches by university administrations. A rich data set consisting of 81
institutions over an 11-year period (1990–2000) that contains, in addition to a coach's race, variables on cumulative winning
records, annual on-the-field improvements, and pre-/post-season game participation by institutions and their coaches is employed.
Our study finds that black coaches, on average, face a dismissal probability that is 9.6 percentage points below that of their
nonblack counterparts, ceteris paribus, suggesting that black head coaches may be the beneficiaries of favorable treatment
by university administrators. Such a result likely stems from universities ' approach to social concerns involving race and
gender issues. This finding also fits a construct that considers workplace discrimination as multi-dimensional. For example,
black representation in the college football coaching ranks may be disproportionately low, possibly as a result of discrimination.
However, once hired, black coaches are given more time to succeed than nonblacks, other things constant. 相似文献

In the present paper, we introduce and study Renyi's information measure (entropy) for residual lifetime distributions. It
is shown that the proposed measure uniquely determines the distribution. We present characterizations for some lifetime models.
Further, we define two new classes of life distributions based on this measure. Various properties of these classes are also
given. 相似文献

Evaluation of trace evidence in the form of multivariate data 总被引:1,自引:0,他引:1

Summary. The evaluation of measurements on characteristics of trace evidence found at a crime scene and on a suspect is an important part of forensic science. Five methods of assessment for the value of the evidence for multivariate data are described. Two are based on significance tests and three on the evaluation of likelihood ratios. The likelihood ratio which compares the probability of the measurements on the evidence assuming a common source for the crime scene and suspect evidence with the probability of the measurements on the evidence assuming different sources for the crime scene and suspect evidence is a well-documented measure of the value of the evidence. One of the likelihood ratio approaches transforms the data to a univariate projection based on the first principal component. The other two versions of the likelihood ratio for multivariate data account for correlation among the variables and for two levels of variation: that between sources and that within sources. One version assumes that between-source variability is modelled by a multivariate normal distribution; the other version models the variability with a multivariate kernel density estimate. Results are compared from the analysis of measurements on the elemental composition of glass. 相似文献
