Effects on students of teacher training in use of a drug education curriculum

The study reported here examines the effects of differential teacher training in use of a drug education curriculum on students' knowledge levels, problem-solving and coping skills, attitudes towards planned decision making, behavioral intentions and tobacco and alcohol use. An experimental design was used to compare the effects of exposure to teachers who had either intensive staff development, in-service training or no training. The findings indicate a statistically significant difference between groups of students on the intention to drink alcohol. Students whose teachers had intensive staff development were less likely to intend to take a drink if offered than students whose teachers had in-service or no training. Possible reasons for a lack of significant results on other variables are the confounding influences of school, classroom and teacher effects.     

Reaching Men who have Sex with Men in Australia. An Overview of AIDS Education: Community Intervention and Community Attachment Strategies

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.     

What really happened? Incidence and factor assessment of abused children and adolescents

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.     

How race affects dismissals of college football coaches

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.     

Renyi's entropy for residual lifetime distribution

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.
