The moderating role of social ties on entrepreneurs depressed affect and withdrawal intentions in response to economic stress. Journal of Organizational Behavior, 33(6): 789-810.,Summary,We explored whether contact

Our proposed stress-buffering model builds on the premise that social ties with similar others can serve as both a source of valuable information and a source of empathic sup

3、port. Findings from a sample of 262 entrepreneurs revealed that the relation between economic stress and intentions to withdraw from entrepreneurial opportunities was stronger among individuals reporting less contact with social ties and weaker among those who reported more contact with social ties.

4、 We further examined the indirect effects of economic stress and contact with business-related social ties on entrepreneurs future intentions through depressed affect. Results showed that among those reporting less contact with social ties, the indirect effect is positive, meaning greater economic s

Among those with more contact with social ties, there is no evidence of this process at work. We interpret this to mean that social ties serve to buffer the impact of economic stres

Those who seem most susceptible to the impact of economic stress are those with relatively limited contact with business-related social ties. We discuss implications and directions for future r

Journal of Applied Psychology, 93(5): 945-958.,Abstract,The present study examines the association between dysfunctional team behavior and team performance. Data included measures of teams dysfunctional behavior and negative affective tone as well as

Utilizing a field sample of 61 work teams, the authors tested the proposed relationships with robust data analytic techniques. Results were consistent with the hypothesized conceptual scheme, in that negative t

On the basis of the findings, the authors conclude that the connection between dysfunctional behavior and

In sum, the findings demonstrated that team members collective emotions and emotional processing represent key mechanisms in determining how dysfunctional team behavior is a
