A sexual assault primary prevention model with diverse urban youth

In this study, a nonprofit community mental health clinic developed a socioecological model of sexual abuse prevention that was implemented in a public school. The goal of the program was to promote and create community change within individuals and the school community by reducing tolerance of sexual violence and sexual harassment. Participants were 5th-12th graders at a school from a Midwest city. Completed measures were obtained from 202 students, and a quasiexperimental time series research design was developed to evaluate the effectiveness of the prevention program. The program was found to be effective at increasing participant's knowledge of sexual abuse, awareness of school and community sexual assault support resources, and identification of components of healthy and unhealthy relationships.     

Chemical and biological agent incident response and decision process for civilian and public sector facilities.

In the event of a terrorist attack or catastrophic release involving potential chemical and/or biological warfare agents, decisionmakers will need to make timely and informed choices about whether, or how, to respond. The objective of this article is to provide a decision framework to specify initial and follow-up actions, including possible decontamination, and to address long-term health and environmental issues. This decision framework consists of four phases, beginning with the identification of an incident and ending with verification that cleanup and remediation criteria have been met. The flowchart takes into account both differences and similarities among potential agents or toxins at key points in the decision-making process. Risk evaluation and communication of information to the public must be done throughout the process to ensure a successful effort.     

Union Formation and Depression: Selection and Relationship Effects

Many studies have established that married people fare better than their never‐married counterparts in terms of psychological well‐being. It is still unclear, however, whether this advantage is due primarily to beneficial effects of marriage or to the selection of psychologically healthier individuals into marriage. This study employs data on young adults from both waves of the National Survey of Families and Households to test hypotheses based on both selection (N= 878) and relationship (N= 722) effects. Further, we differentiate union formation into cohabitation and marriage with and without prior cohabitation. Results indicate no evidence of selection of less depressed persons into either marriage or cohabitation, but a negative effect of entry into marriage on depression, particularly when marriage was not preceded by cohabitation.     

'Given up hope of dying': A child protection approach to deliberate self-harm in adolescents admitted to a paediatric ward

This paper describes an approach developed by a local authority social worker based in a paediatric department, working in close collaboration with consultant child and adolescent psychiatrists and paediatricians. The literature is informative on the significant psychosocial difficulties of young people who harm themselves deliberately, but there is little published work on the complexities of the actual multidisciplinary care given to these patients, the majority of whom are not actively suicidal by the time they are interviewed. The task is as much to intervene in the lives of young people at risk of harm or neglect as to prevent suicide.     

Social Mobility and Participation: The Dissociative and Socialization Hypotheses*

Information on participation with kin, with friends, and in voluntary associations was used to test two competing hypothescs of the effects of social mobility on social relations. The dissociative hypothesis maintains that mobility leads to social isolation, while the socialization hypothesis predicts an adptive outcome to mobility. The relationship is more complex than either position would suggest. Social mobility is associated with isolation from kin and friends, but only for the upwardly mobile. The findings obtained with voluntary associations support the socialization hypothesis in that the level of membership of the socially mobile is intermediate between the two stable groups. Social mobility has maladaptive consequences for more intimate and personal social relations, but it is integrative as far as participation in voluntary associations is concerned.     

A tilting algorithm for the estimation of fractional age survival probabilities

Life tables used in life insurance determine the age of death distribution only at integer ages. Therefore, actuaries make fractional age assumptions to interpolate between integer age values when they have to value payments that are not restricted to integer ages. Traditional fractional age assumptions as well as the fractional independence assumption are easy to apply but result in a non-intuitive overall shape of the force of mortality. Other approaches proposed either require expensive optimization procedures or produce many discontinuities. We suggest a new, computationally inexpensive algorithm to select the parameters within the LFM-family introduced by Jones and Mereu (Insur Math Econ 27:261–276, 2000). In contrast to previously suggested methods, our algorithm enforces a monotone force of mortality between integer ages if the mortality rates are monotone and keeps the number of discontinuities small.

Curricula and State of the Profession

Most of us have encountered problems in developing an effective quantitative analysis program for our business schools in the United States. We have often found managers very reluctant to adopt QA techniques; on the other hand, students, although not reluctant, lacked the necessary mathematical background. During the academic year 1970–71, the authors assisted in the development of a QA department in the business school of a developing nation which offers both resident coursework for graduate students and executives seminars for businessmen. Both the students and the executives had the necessary mathematical background for rapid understanding of QA techniques. The executives appeared eager to use QA in their business operations and the students were highly motivated toward the application of QA to business problems. Our purpose in this article is not to convince all the QA professors to teach in underdeveloped nations, but to furnish information which is likely to be useful to those who attempt to establish similar QA programs in other developing countries.
