Hypermaps: a representation of perceptions in conflicts

An approach to the modelling of conflicts, which is based upon personal construct psychology, is described. Use is made of the idea of cognitive mapping as a way of representing individual perceptions of a situation, and the relationships between the maps held by individuals who are in conflict are expressed by introducing the concept of ‘hypermaps’. The resulting implications for applications of the hypergame approach in practical studies are discussed     

Computing a population budget from sequentially sacrificed, replicated cultures

Summary When a population budget must be obtained from censuses based on replicated, sacrificed cultures, it is difficult to obtain estimates of transition probabilities and of the errors of such estimates, because there is no logical basis for pairing successive census counts. In a study of this nature estimating a population budget of immature stages of the housefly, the problem was solved by a randomization treatment of the original census results obtained at two densities. One hundred randomly generated census matrices over all census times for each density were smoothed to remove the effects of sampling error and a population budget constructed according to defined rules. Transition probabilities computed from the population budget were plotted on triangular coordinate paper and mean probabilities, 95% confidence regions for these means, and 95% equal frequency ellipses computed. All computations and the graphing of the results were carried out on a digital computer. The computer program, available from the authors, is written in FORTRAN IV and could be easily modified for similar studies.

Conventional Ties,Peer Influence,and the Fear of Apprehension: a Study of Adolescent Marijuana Use*

This study examines the relationship between a belief in the certainty of apprehension and self-reported marijuana use; the relative importance of this belief and ties to conventional others as sources of control; and the extent to which involvement with other users is related to the belief examined and use. The findings suggest that both the belief examined and conventional ties, in this case to the family and school. serve as independent sources of control among the high school youth studied. Of particular importance is involvement with other users; use is unlikely given the absence of group supports. This holds both for youth who maintain conventional ties and for those with weak ties. Further, involvement with nonusing peers is related to patterns of use as well as the belief that one will get caught should he try. The effectiveness of the law as a deterrent, then, is questionable given peer involvement and reinforcement for beliefs which effectively discount or support the certainty of apprehension as a viable reason for nonuse.     

Abortion: a psychiatric patient's right to choose

1. Competent mentally ill patients should be allowed to terminate pregnancy. 2. It is the responsibility of the staff to provide the patient with a safe, supportive, and respectful environment. 3.

论互联网条件下的按需报告模式

本文分析了公司报告中多样化和标准化之间的联系。我们认为,“ 围绕标准报告进行按需报告 ”(Customization Around a Standard Report,以下简称CASR)是未来财务报告的一种可行方法。在此方法下,通用财务报告作为基准,保持了信息的可靠性、可比性,以满足使用者的共同信息需求,而附加的按需报告则满足了使用者的不同信息需求。CAS R 仅靠报告公司本身是无法有效实施的。CASR 应当由报告公司、信息中介和最终使用者共同担当,才能发挥更大的效力。这种联合的 CASR 能在 P2P(Peer-to-Peer)的网络互联环境下实现。在此环境下,原始财务数据(如报告公司)以及财务分析师提供的报告均可通过因特网互联和共享。网络环境将对按需报告和标准化产生极大需求。在这种数据互联和文档共享的条件下,为提高未来网上可能出现的大量按需报告的合法性和可靠性,对鉴证服务的需求将大大增加。     

Assessing local capacity for health intervention

Because of their location within the practice realm, participatory, community-based public health coalitions offer many lessons about implementing and sustaining local interventions. This paper presents a case study of capacity assessment at the local level. Capacity evaluation methods are presented, with emphasis on the theoretical framework used to guide the evaluation. The capacity evaluation framework presented herein was theoretically based and designed to generate practical information to facilitate the adoption of a locally tailored youth obesity prevention program, VERB Summer Scorecard (VSS). Using multiple methods, four aspects of community capacity were assessed, including community, knowledge and skills, resources, and power. Within each category, factors that facilitated or impeded program implementation were distinguished. The evaluation protocol was designed to generate information increasing community capacity to sustain a community-based obesity prevention program. Capacity tables were used as a program-planning tool and as a system for sharing implementation and sustainability requirements with potential adopters. This case study also explores how to use capacity assessment results to empower coalitions to serve as catalysts for development of local programs in other communities.     

Anabolic androgenic steroids: use and perceived use in nonathlete college students

OBJECTIVE: The authors investigated the use and perceived use of anabolic androgenic steroids (AAS) among nonathlete college students. PARTICIPANTS: The authors surveyed a sample of 485 nonathlete college students at a major metropolitan university. METHODS: They administered a survey on use and perceived use of AAS to the students. RESULTS: Forty-two participants (9%) reported using AAS (37 men, 5 women). Seniors were the most likely to use AAS (36%), and freshman the least likely (7%). Thirty-four percent of nonusers and 41% of users indicated they knew between 1 and 5 AAS users. Of the total sample, 36% perceived that 5% to 10% of nonathlete college students used AAS. Reasons for AAS use were because friends were using (7%), a desire to enhance physical appearance (45%), and a desire to increase physical performance (48%). CONCLUSIONS: These findings may have significant implications in planning strategic preventive educational programs, and health educators should target incoming college freshmen with the intent of dissuading AAS use.     

Does housework matter anymore? The shifting impact of housework on economic inequality

In recent years, American women’s housework time has declined while American men’s housework time has risen. We examine how these changes have affected economic inequality in the United States. Using time-diary data from the Time Use in Economic and Social Accounts, 1975–1976 (N = 1,484) and the American Time Use Survey, 2003 (N = 5,534), we value adults’ housework using two alternative methodologies and assess its influence on households’ real access to goods and services in both years. Results suggest that housework reduces economic inequality in both years. But, between 1975–1976 and 2002–2003, overall economic inequality rose largely because of the growing wage inequality and also, in part, because of growth in housework inequality. Socio-demographic change partially inhibited the overall growth in economic inequality.

Prevention of family maltreatment in the U.S. Air Force: A systematic review of research on active-duty military personnel

ABSTRACT

Systematic review procedures are used to empirically evaluate the “implicit” logic model that guides the Air Force Family Advocacy Program’s secondary prevention efforts of family maltreatment among active-duty Air Force members. Searches of seven electronic databases and manual searches of 10 journals yielded 586 peer-reviewed articles published in 2000 or later. This review synthesizes the findings of 23 quantitative studies meeting inclusion criteria, including the prediction of some form of family maltreatment among U.S. active-duty military members. Based on review results, we identify critical success variables that function as family protective factors to decrease the likelihood of family maltreatment. These modifiable variables include formal supports, such as ecosystem supports from installation and unit leaders; informal supports, such as the social support of fellow service members and their families; and safe, stable, and nurturing family processes. The results generally align with the implicit logic model but suggest the model should be extended to include intrapersonal vulnerabilities and assets as well as contextual risks and assets. In addition to informing secondary prevention efforts in the Air Force, this novel use of systematic review procedures offers a strategy for evaluating logic models in other areas of prevention research, practice, or policy.
