Too much of a good thing: Underprovision versus overprovision of partner support.

We examined whether support underprovision (receiving less support than is desired) and support overprovision (receiving more support than is desired) should be examined as qualitatively distinct forms of inadequate support in marriage. Underprovision of partner support, overprovision of partner support, and marital satisfaction were assessed 5 times over the first 5 years of marriage in a sample of newlywed husbands and wives (N = 103 couples), and were analyzed via actor-partner interdependence modeling (APIM) and growth curve analytic techniques. Increases in underprovision and overprovision of support were each uniquely associated with declines in marital satisfaction over the first 5 years of marriage; however, overprovision of support was a greater risk factor for marital decline than underprovision. Further, when examining support from a multidimensional perspective, overprovision was at least as detrimental, if not more detrimental, than underprovision for each of 4 support types (i.e., informational, emotional, esteem, and tangible support). The present study is the first to examine the utility of differentiating between underprovision and overprovision of partner support. Theoretical, empirical, and clinical implications are discussed.

Navigating the interdependence dilemma: Attachment goals and the use of communal norms with potential close others.

Four studies investigated attachment in the context of new relationship development. Anxiously attached individuals overwhelmingly used communal norms and avoided using exchange norms when interacting with a potential close other; however, when a potential close other used communal norms, anxious individuals experienced increased interpersonal anxiety. Anxious individuals also used discrete communal behaviors to diagnose relationship potential. By contrast, secure individuals were more comfortable in potential communal situations. Moreover, implicit thoughts about closeness were associated with improved performance on a mental concentration task for secure individuals, whereas implicit closeness thoughts were associated with poorer performance for anxious individuals. Finally, avoidant individuals disliked the potential close other when the other used communal norms and downplayed relational motives for the other's communal behavior.

The effect of goal setting on group performance: A meta-analysis.

Updating and extending the work of O'Leary-Kelly, Martocchio, and Frink (1994), with this meta-analysis on goal setting and group performance we show that specific difficult goals yield considerably higher group performance compared with nonspecific goals (d = 0.80 ± 0.35, k = 23 effect sizes). Moderately difficult and easy goals were also associated with performance benefits relative to nonspecific goals, but these effects were smaller. The overall effect size for all group goals was d = 0.56 ± 0.19 (k = 49). Unexpectedly, task interdependence, task complexity, and participation did not moderate the effect of group goals. Our inventory of multilevel goals in interdependent groups indicated that the effect of individual goals in groups on group performance was contingent upon the focus of the goal: “Egocentric” individual goals, aimed at maximizing individual performance, yielded a particularly negative group-performance effect (d = –1.75 ± 0.60, k = 6), whereas “groupcentric” goals, aimed at maximizing the individual contribution to the group's performance, showed a positive effect (d = 1.20 ± 1.03, k = 4). These findings demonstrate that group goals have a robust effect on group performance. Individual goals can also promote group performance but should be used with caution in interdependent groups. Future research might explore the role of multilevel goals for group performance in more detail. The striking lack of recent field studies in organizational settings that emerged from our brief review of trends in group goal-setting research should be taken into account when designing future studies in this domain.

Understanding the functions of teleconferences for coordinating global software development projects

One of the dominant characteristics of contemporary software development is the global distribution of tasks, of developers, of information and of technologies. Undoubtedly, such distribution engenders new coordination challenges in the form of distance‐related interdependencies. One of the predominant processes of addressing these challenges is electronic meetings (or teleconferences). However, the functions of these meetings for coordination purposes are not yet understood. The distinctive conventions of teleconferences and their causal relationships that lead to optimal coordination of global software development (GSD) projects are also not yet understood. In this paper, the functions of teleconferences held by globally distributed software developers to coordinate their work in the face of global distribution of resources, cross‐site information interdependencies and continuously changing software requirements are analysed. The analysis is based on a qualitative study of how a subunit of 13 software developers, distributed across three sites in the USA and one in Republic of Ireland, used teleconferences to address its coordination challenges. The paper proffers a teleconference approach to GSD coordination by arguing that the functions of teleconferences manifest in software developers' multitasking; their ready access to all their information as additional benefits; flexibility in their communicative behaviours; and a reduction in their structure overload. This approach draws attention to these manifestations as distinctive conventions of the de‐structured meeting, which de‐structuring is occasioned by organic information processing needs in teleconferencing. This approach also explains why the combination of global distribution and teleconferences is a strategic opportunity for information processing for software process coordination.     

Knowing me-knowing you: Reported personality and trait discrepancies as predictors of marital idealization between long-wed spouses.

In previous research, marital idealization has emerged as a significant predictor of adaptation to widowhood, the psychological well-being of spouses of persons with dementia, and the physical health of older married adults over time. Despite the adaptive value of marital idealization, conceptual confusion regarding this phenomenon persists. To this end, the present study examines the degree to which marital idealization is predicted by personality traits relative to partner perceptions of their spouse's personality, and discrepancies between self- vs. spousal reports for both husbands and wives. Multilevel models were computed on the basis of responses from 125 couples married an average of 34 years. Marital idealization by husbands was predicted by his personality (i.e., lower neuroticism, openness to experience, agreeableness, and higher conscientiousness). In contrast, marital idealization by wives was predicted by trait discrepancies (i.e., being seen, and seeing one's spouse, more positively than she or he sees him- or herself). Conscientiousness emerged as the trait for which between-sex differences were most pronounced, whereas both conscientiousness and agreeableness were the traits most broadly associated with marital idealization by both spouses (intracouple trait averages and discrepancies between spousal reports). These results are discussed in relation to gender socialization and between-sex differences. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Application of entropic measures of stochastic dependence in pattern recognition

It is shown that the new entropic measures of stochastic dependence among m variates recently introduced by Watanabe can be usefully employed in the solution of the feature extraction problem of pattern recognition. In particular it is shown that for minimizing the correlations among the components of the random vector in the feature space, in the Gaussian distribution case, the transformation matrix should be formed by using the m eigenvectors corresponding to the m largest eigenvalues of the correlation matrix, rather than the corresponding eigenvalues of the covariance matrix.     

Organizational Partnerships in China: Self-Interest, Goal Interdependence, and Opportunism.

Opportunism in organizational partnerships may be understood in terms of how partners conclude that their self-interests are related to each other. When partners believe that their goals are competitively but not cooperatively related, they are tempted to pursue their self-interests opportunistically. Cognitive understandings and values of a shared vision may help partners believe their goals are cooperatively related. Results from 103 pairs of customer and supplier organizations support the argument that partnerships are not inevitably threatened by opportunism. Using structural equation analysis, the authors suggested that shared vision can help partners develop cooperative goals that lead to low levels of opportunism. These results suggest that a shared vision and cooperative goals are important foundations for effective organizational partnerships. (PsycINFO Database Record (c) 2011 APA, all rights reserved)
