Purpose– Extant literature has looked at the effect of alliance capability and organizational culture on alliance portfolio performance, but the relationship between the two has not been explored. The purpose of this paper is to explore the hypothesis that an alliance supportive culture is not only fostered by a firm's alliance capabilities, but that it mediates the relationship between capabilities and performance.Design/methodology/approach– Survey responses from 190 alliance managers, collected using a two-stage process, were analyzed to investigate the interrelationship of firm-level alliance capability, alliance supportive culture and portfolio performance.Findings– Alliance supportive culture was found to mediate the relationship between alliance capability and alliance portfolio performance. This finding suggests that in order to effectively manage a firm's portfolio of alliances, the benefits of alliance capability must be transferred broadly into the organization's cultural orientation toward alliances.Research limitations/implications– Further research may extend this analysis to explore the effect of subcomponents of alliance capability and alliance culture to better understand fine-grained influences on alliance performance. The findings of this study also may be extended to inform how supportive culture orientation affects partner selection, negotiation and time to performance.Practical implications– Managers should utilize culture-building actions as a way of extending the value of their firms' alliance capabilities in order to improve their effectiveness across the portfolio.Originality/value– Extant studies have considered the discrete effects of capability and cultural orientation on alliance portfolio success, but the mediation effect has not previously been investigated. The findings also identify a boundary condition for the benefit of alliance capabilities on portfolio performance.

Fifty-three elderly men and 51 elderly women participated in a study of the relationship between suicidal ideation and selected personal, stress, and social support variables. A multifactor theory formed the basis for the selection of variables, which included age, gender, marital status, living arrangements, perceived religiousness, alcohol use, self-esteem, depression, negative stress, satisfaction with health, social isolation, and satisfaction with social support. Bivariate correlation analyses found suicidal ideation to be related to infrequent alcohol consumption, high depression, high social isolation, and dissatisfaction with health and social support. Results of a multiple regression analysis identified (dis)satisfaction with social support, gender, living arrangements, and (in)frequency of alcohol use as significant predictors.

Ninety-two university students (55 women; 37 men) participated in a study of the relationship between authoritarian and socially restrictive attitudes toward mental patients and the variables of trait -anxiety, self-esteem, locus of control, age, and gender. Results of multivariate
analyses showed that individuals who score high in authoritarianism tend to be young, male, and believers in chance and fate (external locus of control). A similar pattern was found for social restrictiveness.

English-Canadian high school students (60 boys, 51 girls) participated in a study of the reliability and validity of a self-report version of the Scale for Suicide Ideation. Item analysis, coefficient alpha, and split-half coefficient suggested good reliability. Correlations with selected
personality variables were obtained. Associations were found between suicide ideation and measures of self-esteem, external locus of control, anomy, negative stress, and depression. The scale's correlational characteristics agreed with findings reported in the literature.

Sixty undergraduate university students participated in a study of the relationship between repression-sensitization and selected measures of adjustment, namely, degree of conflict, self-esteem, alienation, anomy, and locus of control. Results indicated that sensitizers tend to report
lower levels of self-esteem; greater alienation, anomy, and conflict; and externality. Further analyses identified alienation and particularly self-esteem as best predictors of defensive orientation.
