Selection of cost-optimal 2k−p fractional factorials

Selecting an optimal 2^k?pfractional factorial is structured as a mathematical programming problem. An algorithm is defined for the solution, and the case of additive costs is shown to have a known solution for resolution III designs.     

Marital Aspirations,Sexual Behaviors,and HIV/AIDS in Rural Malawi

We explore how marital aspirations are related to the sexual behaviors of adolescents and young adults in Malawi, where HIV/AIDS prevalence among adults exceeds 10%. We also consider whether the specter of AIDS is shaping ideals about marriage. By combining survey data (N = 1,087) and in‐depth interviews (N = 133) with young Malawians from the Malawi Diffusion and Ideational Change Project, we show that looking for and finding a suitable spouse are linked to sexual behaviors and, thus, HIV risks. Moreover, concerns about contracting HIV are closely tied to the ideal characteristics of a future spouse. Our findings draw long‐overdue attention to the importance of marital aspirations in understanding adolescent sexual behaviors and risks in the era of AIDS.     

Strategic management and artificial intelligence

The presence today of ‘thinking’ robots has great implications for general management (as opposed to production management). The possibility is clear that within a decade a supercomputer may share or usurp functions of a corporate chief executive—functions that up to now have been thought unsharable. Now is the time to begin planning for such a development.     

Son preference and sex composition of children: Evidence from india

Although the effect of son preference on sex composition of children ever born is undetectable in national-level estimates that aggregate across all families, this article provides empirical evidence from India that son preference has two pronounced and predictable family-level effects on the sex composition of children ever born. First, data from India show that smaller families have a significantly higher proportion of sons than larger families. Second, socially and economically disadvantaged couples and couples from the northern region of India not only want but also attain a higher proportion of sons, if the effects of family size are controlled.     

Character-Based Determinants of Trust in Leaders

Trust is a prominent determinant of effective interpersonal relationships, group process, and organizational development. However, for leaders and managers, trust building is often problematic. The aim of this article is to contribute to a growing understanding of the way in which individual managers can develop trust in organizations, particularly those defined by medium to high risk. The article presents a theoretical and empirical analysis of the nature of trust at work. Building on the results of an earlier study, use is made of the facet-theoretical approach to generate a definitional framework of trust, which focuses on the characteristics of the trusted person that contribute to the development of trust. Using items developed on the basis of a mapping sentence, hypotheses regarding the relations between the definitional framework and empirical observations were tested through smallest space analysis (SSA) of data collected from a sample of 398 bank and hospital employees. The results demonstrate strong support for the definitional system and show a clear association with results of prior research that identify perceptions of ability, integrity, fairness, and openness as key determinants of trust. The empirical structure clearly reflects the attitudinal nature of interpersonal trust at work and the items empirically distinguish distinct character-based components of trust.     

Residential substance abuse treatment for pregnant and postpartum women and their children: treatment and policy implications

In FY 1993 and FY 1995, the federal government awarded 27 five-year grants that supported 35 residential treatment projects for substance-abusing pregnant and postpartum women and their children. These projects provided comprehensive culturally and gender-specific treatment. Preliminary aggregated data collected in a national cross-site evaluation of 24 of these projects are encouraging with respect to infant mortality and morbidity, treatment retention and completion rates, and behavioral changes in the participating mothers at six months postdischarge. Local evaluations reflect other benefits of treatment. Cost data are expected to demonstrate the efficiencies and benefits of these projects compared to no treatment.     

A randomized trial of emotion-focused therapy for couples in a training clinic

Forty married couples participated in a randomized trial comparing 8 weekly sessions of emotion-focused therapy (EFT) for couples to a group of couples who were placed on an 8-week waiting list. A composite marital satisfaction score was created from scores on the Dyadic Adjustment Scale, Positive Feelings Questionnaire, and Personal Assessment of Intimacy in Relationships scale. Controlling for pretest scores, participants in the treatment group had significantly higher levels of marital satisfaction after 8 weeks than wait-list participants. Supplementary analyses identified variables associated with gains in therapy and with dropping out of the study.     

Turnover turned over: an expanded and positive perspective

The negative impact of turnover is well documented in the literature. This paper examines turnover with a unique, positive focus. Turnover is reviewed, not only from the standpoint of the organizational theorist, but with economic, sociological, and psychological/social psychological perspectives. Often ignored benefits of turnover are noted.
