A uniform saddlepoint expansion for the null‐distribution of the wilcoxon‐mann‐whitney statistic

The authors give the exact coefficient of 1/N in a saddlepoint approximation to the Wilcoxon‐Mann‐Whitney null‐distribution. This saddlepoint approximation is obtained from an Edgeworth approximation to the exponentially tilted distribution. Moreover, the rate of convergence of the relative error is uniformly of order O (1/N) in a large deviation interval as defined in Feller (1971). The proposed method for computing the coefficient of 1/N can be used to obtain the exact coefficients of 1/Nⁱ, for any i. The exact formulas for the cumulant generating function and the cumulants, needed for these results, are those of van Dantzig (1947‐1950).     

Jobs,gender, and self‐efficacy in multiple contexts

This paper focuses on the social psychological correlates of being in an occupation that is sex‐typed against one's own gender‐i.e., cross‐sex incumbency in sex‐typed occupations. Male and female high school teachers and university professors are compared in terms of global self‐esteem as well as in three context‐specific dimensions of self‐efficacy. While no differences in global self‐esteem were revealed, a number of significant differences did emerge in comparisons of self‐efficacy in specific contexts. Our data reveal no uniform effects of cross‐sex incumbency. Male high school teachers, however, did exhibit signs of decreased occupational self‐efficacy, perhaps as a result of the previous female domination of that occupation. Female professors, on the other hand, reported high levels of self‐efficacy on all dimensions. The paper concludes with two hypotheses for further empirical examination, and suggests tht self‐esteem be conceptualized as a multidimensional construct.     

Diversification and Extensible Networks: The Strategies of Chinese Businesses in Australia1

DIVERSIFICATION ET RÉSEAUX EXTENSIBLES: LES STRATÉGIES DES ENTREPRENEURS CHINOIS EN AUSTRALIE
Cet ouvrage rend compte d'une enquête effectuée dans 28 entreprises créées par des Chinois de souche à Brisbane, Adélaïde et Perth et réalisée en 2000–2001. Elle met surtout l'accent sur les stratégies des immigrés en termes de diversification verticale, horizontale et non corrélée en combinant souvent différents produits, marchés et activités. Elle démontre combien ces pratiques sont socialement ancrées dans le système qui porte les migrants à préférer les réseaux personnels.
La diversification non corrélée en particulier se trouve favorisée et facilitée par l'usage de ierelations lâchesli servant de relais et donnant accès à de nouveaux réseaux (Granovetter, 1973). Cela permet de nouer des liens avec les Chinois d'origines nationales différentes et parlant des dialectes différents, ainsi qu'avec des membres chinois d'autres groupes ethniques. Les auteurs émettent l'opinion selon laquelle les réseaux ouverts et la diversification interagissent mutuellement, ce qui fait que chaque partie en tire profit, et qu'ils ont probablement évolué en tandem au départ de cultures et de pratiques commerciales antérieures, plus fermées et à caractère de niche.     

Therapy with Infertile Heterosexual Couples: It’s Not About Gender—Or is it?

In spite of medical data that show males are equal to their female partners as a source of a heterosexual couple’s infertility, therapists face many unanswered questions about the extent to which gender influences each partner’s infertility experience in American culture. How is “hers” different from “his?” To what extent should the therapist strive to help the couple define the infertility issue as “ours”? This article explores how the therapist can elicit and be sensitive to gender issues while fostering resilience in the infertile couple.     

Friends don't let friends ...or do they? Developmental and gender differences in intervening in friends' ATOD use

This study focused on the strategies adolescents endorsed for situations in which friends were experimenting with alcohol, tobacco, and other drugs. Four hypothetical vignettes (concerning a friend smoking, using drugs, getting drunk at a party, or deciding whether to attend a party with alcohol and drugs) were presented to 2697 5th-12th graders. Whereas younger students were more likely to choose proactive strategies (talking to the friend or an adult or ending the friendship), older students were more inclined to say they would ignore a friend's smoking and drug use although they would take the car keys away from a friend drinking alcohol. Among those 13 years old and older, the more dangerous the substance, the more inclined the youth were to intervene. Females were more inclined than males to talk to friends about smoking, drinking, and drugs and less inclined to ignore the behaviors or stop being a friend.     

Social capital and women's reduced vulnerability to HIV infection in rural Zimbabwe

Social capital—especially through its “network” dimension (high levels of participation in local community groups)—is thought to be an important determinant of health in many contexts. We investigate its effect on HIV prevention, using prospective data from a general population cohort in eastern Zimbabwe spanning a period of extensive behavior change (1998–2003). Almost half of the initially uninfected women interviewed were members of at least one community group. In an analysis of 88 communities, individuals with higher levels of community group participation had lower incidence of new HIV infections and more of them had adopted safer behaviors, although these effects were largely accounted for by differences in socio-demographic composition. Individual women in community groups had lower HIV incidence and more extensive behavior change, even after controlling for confounding factors. Community group membership was not associated with lower HIV incidence in men, possibly refecting a propensity among men to participate in groups that allow them to develop and demonstrate their masculine identities—often at the expense of their health. Support for women's community groups could be an effective HIV prevention strategy in countries with large-scale HIV epidemics.     

Analyzing Cultural Models in Adolescent Accounts of Romantic Relationships

Research on academic achievement has led the way in demonstrating how culturally constructed meanings shape adolescent scholastic behavior. The aim of this research is to move this standpoint of analysis more centrally into the area of adolescent dating and sexuality by focusing on the cultural components of adolescent romantic relationships. This study examines cultural models of romantic relationships in Vernacular Term Interviews of 68 African American and 59 Mexican American 11th‐ and 12th‐grade female and male high school students. A subset of interviews was analyzed first qualitatively to identify the models. The models then were committed to a manual and 4 analytic coders established reliability before coding all interviews blind as to race/ethnicity and gender of the adolescent. The resultant data were summarized by a principal components analysis that yielded 5 interpretable factors. Factor scores were computed and compared for gender and race/ethnicity differences. The results demonstrated clear differences in factors by race/ethnicity but not by gender. Results are discussed in relation to cultural differences described in the literature for these 2 populations.     

EMPLOYER CHOICES IN EAP DESIGN AND WORKSITE SERVICES

In today's complex private healthcare market, employers have varied preferences for particular features of behavioral health products such as Employee Assistance Programs (EAPs). Factors which may influence these preferences include: establishment size, type of organization, industry, workplace substance abuse regulations, and structure of health insurance benefits. This study of 103 large employer purchasers from a single managed behavioral healthcare organization investigated the impact of such variables on the EAP features that employers select to provide to workers and their families. Our findings indicate that for this group of employers, preferences for the type and delivery mode of EAP counseling services are fairly universal, while number of sessions provided and choices for EAP-provided worksite activities are much more varied, and may be more reflective of the diverse characteristics, organizational missions and workplace culture found among larger employers in the US.     

Employment and unemployment patterns in the U.S. and Europe, 1973–1987

Employment trends in the United States and Europe are compared using Bureau of Labor Statistics data. These data set the stage for a discussion of the difference in employment growth between the U.S. and Europe. Also included are some elements that may partly explain the U.S. and European differences in job growth. In conclusion, labor market problems still remain even with the tremendous job growth in the U.S.     

Survivors of suicide. Emerging counseling strategies

1. Effective intervention with survivors of suicide requires knowledge of the diverse sequelae of response including blame, anger, guilt, shame, search for why, and feelings of stigmatization. 2. Fearing blame and stigmatization, survivors of suicide may be reluctant to contact helping professionals. 3. Duration and intensity of bereavement is mediated by the survivors' nature of the relationship with the deceased and their perception of the preventability of the death. 4. Group counseling is an effective intervention because it addresses the issue of disenfranchised grief.
