My Mentor,My Self: Antecedents and Outcomes of Perceived Similarity in Mentoring Relationships

This study examines the antecedents and outcomes of perceived similarity in mentoring relationships in a sample of 82 matched mentor-protégé dyads. Polynomial regression analyses were used to examine the association between actual and perceived similarity. Protégés were more likely to see themselves as similar to their mentors when they and their mentors shared either higher or lower levels of attachment security. However, sharing similar levels of relational self-construal was unrelated to protégés perceptions of similarity with their mentors. Path analyses revealed that protégés reported more organizational and professional commitment when they saw themselves as similar to their mentors, and that these associations were mediated by protégés’ reports of their mentors providing role modeling functions. These findings suggest that the effects of actual mentor-protégé similarity on perceptions of similarity may depend on the shared attribute, and provide further evidence of the importance of perceived similarity to not only mentoring relationships, but also to organizations.     

Optimism as modifier of escalation of commitment

To study whether optimism-pessimism modifies escalation of commitment, 52 undergraduates were told that they had made an unsuccessful investment, then they chose to continue or discontinue this investment. Optimism about future returns was induced in one group by varying the probability of a successful outcome from an initial low to medium, pessimism was induced in another group by varying this probability from an initial high to medium. Supporting the assumption of the manipulation, the results showed that optimistic participants preferred to continue investments whereas pessimistic participants preferred not to. As predicted, when the sunk cost increased, optimism led to escalation of commitment, whereas pessimism led to de-escalation of commitment. These effects were strengthened when probability of a successful outcome was ambiguous.     

Effects of team and organizational commitment – A longitudinal study

Retention management, i.e., keeping qualified employees, is a top priority for contemporary organizations. Commitment, and especially team commitment, can be the key to mastering this challenge. There is a lack of longitudinal research concerning the development and the direction of the effects of team commitment over time. In a longitudinal field-study design with three points of measurement, a total of 360 employees in 52 semi-autonomous industrial teams were surveyed over a period of three years. On the one hand, organizational commitment showed stronger effects on organization-related criteria (job satisfaction and intention to leave). These effects were consistent over the three points of measurement. Team commitment, on the other hand, affected team-related criteria (team performance and altruism). Longitudinal analyses confirmed the effects of organizational commitment on job satisfaction and intention to leave, and of team commitment on team performance and altruism. Moreover, these effects increased over time. Theoretical and practical implications of these findings are discussed.     

Balance between volunteer work and family roles: Testing a theoretical model of work‐family conflict in the volunteer emergency services

Trends indicate overall declines in numbers of volunteer emergency service workers and suggest negative organisational factors impacting adversely on volunteers and organisations. Conflict between emergency service work and family is implicated in falling volunteer numbers, and there is thus a need for research on difficulties experienced in balancing volunteer work and family. The current study tested an adaptation of the work‐family conflict (WFC) model originally proposed by Frone, Russell, and Cooper, in a sample of 102 couples in which one partner was an Australian emergency service volunteer. Results supported a model in which volunteer work‐related antecedents, including time invested in on‐call emergency activities and post‐traumatic stress symptoms, had indirect links with outcomes, including volunteer burnout and their partners' support for the volunteer work role, through the effects of WFC. These results add to research using theoretical models of paid work processes to better understand the problems faced by volunteer workers, and identify specific antecedents and outcomes of WFC in the volunteer emergency services. Implications for future research and organisations reliant on volunteer workers are discussed.     

A randomised worksite comparison of acceptance and commitment therapy and stress inoculation training

In this comparative intervention study, 107 working individuals with above average levels of distress were randomly assigned to one of three conditions: acceptance and commitment therapy (ACT; n = 37); stress inoculation training (SIT; n = 37); or a waitlist control group (n = 33). The interventions were delivered to small groups in the workplace via two half-day training sessions. ACT and SIT were found to be equally effective in reducing psychological distress across a three month assessment period. Mediation analysis indicated that the beneficial impact of ACT on mental health resulted from an increase in psychological flexibility rather than from a change in dysfunctional cognitive content. Contrary to hypothesis, a reduction in dysfunctional cognitions did not mediate change in the SIT condition. Results suggest that the worksite may offer a useful, yet underutilised, arena for testing cognitive-behavioural theories of change.     

Bases of social power,leadership styles,and organizational commitment

Affective organizational commitment reflects the extent to which organizational members are loyal and willing to work toward organizational objectives (Meyer & Allen, 1997). In particular, affective organizational commitment holds very important implications at all organizational levels (e.g., turnover rates, performance, and citizenship behavior). Whereas previous research has evinced the positive influence of transformational and charismatic leadership styles on affective commitment toward the organization (Bass & Avolio, 1994), little is known with regard to the nature of this relationship. In line with the interpersonal power/interaction model, the present investigation aimed to investigate the mechanism at play between transformational leadership style and affective organizational commitment. Specifically, we hypothesized that transformational leadership style would increase affective organizational commitment through its effect on willingness to comply with soft bases of power. In two studies, we subjected the foregoing hypotheses to empirical scrutiny. In Study 1, the proposed mediation model was empirically supported with Italian employees in the public sector. Attesting to the robustness of our findings, Study 2 replicated the findings of Study 1 with Italian employees from the public and private sectors. In addition, Study 2 replicated Study 1 using a different measure of transformational leadership. Both Study 1 and Study 2 provided results consistent with our hypotheses. Specifically, the present paper reports empirical evidence that (1) the more participants report having a transformational leader, the more willing they become to comply with soft (but not harsh) power bases, (2) in turn, greater willingness to comply with soft (but not harsh) power bases increases one's affective organizational commitment. These findings provide additional support for the interpersonal power/interaction model and pave the way for new research directions.     

Organizational Commitment,Job Satisfaction,and Effort in the Service Environment

Investigations of the causal relationship between organizational commitment and job satisfaction have yielded contradictory findings. Little empirical research has looked at this complex relationship in the context of work effort. The purpose of this study was to determine how these variables interact in the service environment. Using a sample of 425 employees in two service organizations, the author tested two structural equation models. The hypothesized model with organizational commitment as a moderator between job satisfaction and service effort fit better than a model with job satisfaction as moderator did. Conceptual implications are discussed, and suggestions for future research are made.     

A Method for the Study of Personality Reactions in Preschool age Children by Means of Analysis of their Play

This investigation studied variability in visual thresholds for six subjects for 50 consecutive days. The results show the following:

1. Session-to-session variability agrees closely with the variability estimates made by Hecht and Zegers.

2. No periodic or cyclic trends appeared for the group or for any individual subject.

3. For all six subjects for the first 15 days of testing, a learning phenomenon was observed for the mean and standard-deviation data. There was a slow rise over the last 10 days of testing for the mean, but not for the standard-deviation data. (A discussion of the possible causes of the rise of the mean over the last 10 days suggested the influence of extraneous factors, such as boredom and fatigue.)

4. No effect of the menstrual cycle upon the threshold values was found.

4. No effect of the menstrual cycle upon the threshold values was found.
