The mentor advantage: Perceived career/job experiences of proteges versus non-proteges

Do proteges report having more positive job/career experiences than non-proteges? Do male proteges report having more favorable job/career experiences than female proteges? Do high-level proteges report having more favourable work experiences than low-level proteges? To answer these questions, mentored and non-mentored men and women in high- and low-level positions were asked to evaluate, on a survey questionnaire, their level of satisfaction, career mobility/opportunity, recognition, security and promotion rate. The extent to which these career/job experiences varied as a function of their mentored status, sex and organizational level was examined. The results of the study revealed that mentored individuals reported having more satisfaction, career mobility/opportunity, recognition and a higher promotion rate than non-mentored individuals. However, proteges' perceptions of their job/career situations were not affected by their sex or level. Whether systematic differences exist in the experience of being mentored has yet to be examined.

Examination of the combined effects of work values and early work experiences on organizational commitment

We tested the hypothesis that the influence of early work experiences on organization commitment would be moderated by the value employees place on these experiences. We measured work values in two samples of recent university graduates prior to organizational entry, and obtained measures of commensurate work experiences and three forms of commitment (affective, continuance, and normative: Allen and Meyer, 1990) on different occasions following entry. Regression analyses revealed that values and experiences did interact in the prediction of affective commitment and normative commitment, but that the nature of the interaction was different for different work value/experience combinations. The findings provide some challenge to the common sense assumption that positive work experiences will have the strongest effect on commitment among those who most value such experiences. Implications for research and practice are discussed. © 1998 John Wiley & Sons, Ltd.     

Recovery from work‐related effort: A meta‐analysis

This meta‐analytic study examines the antecedents and outcomes of four recovery experiences: psychological detachment, relaxation, mastery, and control. Using 299 effect sizes from 54 independent samples (N = 26,592), we extend theory by integrating recovery experiences into the challenge–hindrance framework, creating a more comprehensive understanding of how both after‐work recovery and work characteristics collectively relate to well‐being. The results of meta‐analytic path estimates indicate that challenge demands have stronger negative relationships with psychological detachment, relaxation, and control recovery experiences than hindrance demands, and job resources have positive relationships with relaxation, mastery, and control recovery experiences. Psychological detachment after work has a stronger negative relationship with fatigue than relaxation or control experiences, whereas control experiences after work have a stronger positive relationship with vigor than detachment or relaxation experiences. Additionally, a temporally driven model with recovery experiences as a partial mediator explains up to 62% more variance in outcomes (ΔR² = .12) beyond work characteristics models, implying that both work characteristics and after‐work recovery play an important role in determining employee well‐being.

Rested,friendly, and engaged: The role of daily positive collegial interactions at work

This diary study examined within‐person effects of positive work and off‐work experiences on daily work engagement. Assessing the gain cycle assumption of conservation of resources theory, we investigated the relationship of nighttime recovery experiences and subsequent resources including elevated sleep quality and morning positive affect; the relationship of morning positive affect with positive collegial interactions and subsequent work engagement; and the relationship of work engagement with nighttime recovery experiences. Sixty‐nine employees completed 3 daily questionnaires over 5 consecutive working days. Multilevel analyses revealed that sleep quality positively predicted morning positive affect, which in turn predicted work engagement directly and also indirectly through having positive interactions with colleagues. Work engagement positively predicted nighttime recovery experiences, whereas nighttime recovery experiences were not related to sleep quality or morning positive affect the next day. Overall, on days after a good night's sleep, individuals feel more positive, bring this positivity to their workplace, reach out to their workplace colleagues, and are in turn more likely to be engaged in their work. Additionally, on days when individuals experience higher levels of positive collegial interactions at work and in turn higher work engagement, they are likely to enjoy better recovery experiences.

Demographic similarity to the work group: A longitudinal study of managers at the early career stage

A sample of 141 Canadian business school graduates responded to questionnaires at 3, 9 and 14 months after beginning full-time jobs. Their job experiences including challenge, work group fit, supervisor support, and mentorship were measured along with organizational commitment, turnover, and promotion. There was little evidence of treatment discrimination against the female and minority members of the sample. However, dissimilarity to one's work group in terms of age, education, and lifestyle meant lower job challenge and poorer work group fit. In contrast, being dissimilar in terms of gender meant greater challenge, and, if the manager was male, greater likelihood of promotion. Being dissimilar in terms of culture was not associated with any of the job experiences. Relationships between the early experiences and organizational commitment were strongest for those who were most dissimilar in terms of gender, whereas relationships between the experiences and turnover were strongest for those who were most dissimilar in terms of age, education, and lifestyle.

Fathers' work experiences,the father-child relationship and children's behaviour

The effects of fathers' subjective work experiences on their children's behaviour have been largely neglected, despite increasing recognition accorded to the fathers' role in all aspects of child development. The present study redresses this issue by assessing whether (a) fathers' work experiences are related to children's behaviour, (b) the father-child relationship moderates the effects of fathers' work experiences on children's behaviour, and (c) specific child behaviours are associated with paternal work experiences. One hundred and forty two fathers (M age = 39.55 years) and their eldest child (M age = 9.2 years; 66 boys, 76 girls) participated. Moderated multiple regressions demonstrated that fathers' job satisfaction was related to specific child behaviours, viz. conduct problems and hyperactivity. More importantly, the father-child relationship moderated both these relationships: Where fathers were dissatisfied with their jobs, conduct problems and hyperactivity were significantly greater when the father-child relationship was of a higher quality. Implications for studying the effects of both mothers' and fathers' work experiences on their children's behaviour are drawn.     

Antecedents and consequences of relational components of the new psychological contract

The literature regarding the new psychological contract suggests that the traditional paternalistic employer–employee relationship in U.S. companies has eroded. We investigated the relationship between relational components of the new psychological contract (personal responsibility for career development, commitment to type of work, and expectations of job insecurity), work experiences (involuntary job loss, organizational change, voluntary job change, and violation of obligations), and work outcomes (job satisfaction, participation in development activities, and intention to remain with the employer). We hypothesized that managerial and professional employees' level of agreement with relational components of the new psychological contract would mediate the relationship between their work experiences and work outcomes. In partial support of the model, we found that level of agreement with relational components of the new psychological contract mediated the relationship between work experiences and intention to remain with the employer and job satisfaction. Contrary to the model, no relationship was found among work experiences, level of agreement with relational components of the new psychological contract, and participation in development activities.

Numerical investigation of effects on premixed hydrogen/air flame propagation in pipes with different contraction or expansion angles

Numerical simulations of premixed hydrogen-air flame propagation in a pipe with different contraction or expansion angles are carried out in this study. The effects on the flame propagation characteristics are investigated, including flame shape, the speed of flame front and overpressure. Results show that the flame propagation at different contraction angles experiences 6 flame stages: spherical flame stage, finger-shaped flame stage, stage of flame front touching the sidewalls, classic tulip flame stage, dissipation stage of tulip flame and its re-formation stage. The formation of tulip flame and the following stages are promoted by the contraction structure. Meanwhile, the development of the flow and pressure fields near the contraction are analyzed and it is found that the paraclinical effects induced by the contraction angle enhance the tulip re-formation. In the sudden expansion pipes, a triple flame stage appears in the pipes. The flame front remains relatively static for a period of time. However, the flame would continue to propagate when the expansion angle becomes larger and the flame propagation distance in the ducts increased obviously with the larger expansion angle. Baroclinic effect can inhibit the intensity of the vortex in the flow field, and hence weaken the forward transport of fuel. This inhibit effects decrease with the expansion angle becomes larger. The results of this study have implications concerning designs for pipe geometry of hydrogen and may help get better hydrogen transportation.
