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.     

Paradoxes, locations and the need for social coherence: a qualitative study of living with a learning difficulty

Policy rhetoric over recent decades has promoted social inclusion of the more vulnerable sectors of society, such as people with learning difficulties. This study aimed to describe the experiences of people who live with learning difficulties in order to inform local service development. Thirty-five people with a learning difficulty and/or a family member were interviewed. A model of social coherence was developed that moves beyond the self-limiting debates about social inclusion and exclusion. It is underpinned by a sense of location for the person with a disability in relation to services and carers, family and community, dependency and risk, temporality and space, events, control and society. Key recommendations are for services to know the individual and his/her family; to be responsive to individual needs; to enhance the capacity of families and communities to support people with difficulty in learning; and to help these people to feel more valued.     

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.     

Team resilience: A scoping review of conceptual and empirical work

ABSTRACT

The purpose of this scoping review was to examine the literature on team resilience to gain insight into current thinking regarding its definition and conceptualisation, and to identify how researchers have operationalised and measured this concept. We conducted a systematic scoping review using the 5-phase approach proposed by Arksey and O’Malley. A total of seven databases were searched, followed by a citation search of eligible papers via Google Scholar. Of the 275 articles identified via the search process, 27 papers were deemed eligible for review. Several key findings regarding the literature on team resilience were observed: (i) definitions varied in terms of content (e.g. input or process), breadth (e.g. unidimensional versus multidimensional), and quality (e.g. essential and necessary attributes of key components); (ii) there was a predominance of single-level conceptualisations of team resilience; and (iii) there has been a reliance on cross-sectional research designs in empirical studies, which is incongruent with the dynamic nature of this concept. Key recommendations from this scoping review focus on definitional, theoretical, and methodological issues.     

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.
