Longitudinal effects of lean production on employee outcomes and the mediating role of work characteristics 总被引:2,自引:0,他引:2
Parker SK 《The Journal of applied psychology》2003,88(4):620-634
The author discusses results from a 3 year quasi-experimental field study (N = 368), which suggest negative effects on employee outcomes after the implementation of 3 lean production practices: lean teams, assembly lines, and workflow formalization. Employees in all lean production groups were negatively affected, but those in assembly lines fared the worst, with reduced organizational commitment and role breadth self-efficacy and increased job depression. A nonequivalent control group had no negative changes in outcomes. Mediational analyses showed that the negative effects of lean production were at least partly attributable to declines in perceived work characteristics (job autonomy, skill utilization, and participation in decision making). The study also shows the longitudinal effects of these work characteristics on psychological outcomes. Implications for lean production, work design, and employee well-being are discussed. 相似文献

The present research sought to establish a reliable and valid instrument for assessing the relevance of neoconditioning factors (e.g. latent inhibition, UCS inflation/revaluation, prior fear levels, prior expectancies of harm, fear and pain levels experienced during supposed learning events), in the development of human fear. Fifty-four undergraduate height-fearful students completed the new origins instrument (OQ-II), while 54 matched controls completed a modified version (OQM-II) that examined their prior experiences with heights. In general, few differences between groups were found. Height-fearful and control subjects did not differ on trait anxiety, the frequency of negative encounters with heights, the age at which these events had occurred, prior fear levels, prior expectancies of harm, or reports of UCS inflation/revaluation procedures. However, in a finding directly opposite to that expected from a conditioning account, the mean fear and pain scores reported by subjects who had experienced direct conditioning events were significantly higher in the non-fearful group than in the height-fearful group. These findings are discussed in terms of associative and non-associative models of fear. 相似文献

This is a study of psychosocial outcomes of adolescents born to teenage mothers. Adolescents' problem behaviors, psychological well-being, social support, school variables, and sexual behaviors are compared across three groups—those born to mothers 17 or younger, mothers 18–19 years old, and mothers 20 or older. Analyses from two samples of African American adolescents from Maryland (n = 205) and Michigan (n = 570) are reported. The results from both samples indicate that mother's age at birth is unrelated to adolescents' psychosocial outcomes. These two studies add to the limited number of analyses that examine adolescent outcomes for children of teen mothers. The results suggest that efforts to understand social structural determinants of healthy and problematic adolescent development may be more informative than examining the effects of mother's age. They also suggest that teen pregnancy prevention programs may be more effective if they are part of a larger prevention strategy that incorporates social structural change efforts and not only a focus on individual level change. 相似文献

During summer, female meadow voles (Microtus pennsylvanicus) maintain territories and males do not engage in paternal care. As day length shortens, territories dissolve and males nest with females and young. Because paternal behavior has never been studied in free-living meadow voles during colder months or in the laboratory under short photoperiods, the authors examined whether males housed in short day (SD) lengths exhibited more frequent or better quality paternal behavior than males housed in long day (LD) lengths. Sexually and parentally inexperienced (naive) SD males exhibited proportionally more and qualitatively better paternal care than naive LD males. SD males were more responsive than LD males to classic social cues associated with prepartum aggression inhibition and paternal onset. SD sires also displayed qualitatively better paternal behavior than LD sires. These data suggest that meadow vole paternal state is regulated by specific social and environmental cues that may contain reliable information about ecological conditions that favor paternal care. 相似文献

One extreme or the other or perhaps the golden mean? Issues of spatial resolution in face processing
The findings of some of the key studies that have examined the contribution of different bands of spatial information, specified
in terms of cycles per face, to face recognition, and identification are reviewed. Based on findings from studies of low-,
high-, and band-pass filtering, it is concluded that neither low facial scales nor high facial scales are optimal. Instead,
a center range of facial scales, approximately 8-16 cycles per face, appears to make the greatest contribution to the recognition
process. A study of identification of band-pass filtered faces is reported that reinforces the view derived from the literature.
This indicated that a band with a harmonic mean of 11.1 cycles per face provided the most efficient recognition, with speed
and accuracy declining at lower and higher bands. 相似文献

Empirical evidence and theory implicate the role of distress tolerance in the relationship between negative affect and alcohol use. However, limited research has been conducted to explore these relationships. As such, the purpose of this study was to examine whether distress tolerance moderates the relationship between current depressive symptoms and problematic alcohol use in a community sample of adults. Participants included 150 adults, primarily female, recruited from the local community. Problematic alcohol use was measured using the Alcohol Use Disorders Identification Test (AUDIT) total score, which is a composite measure of harmful and hazardous patterns of alcohol use and several current alcohol dependence symptoms. Distress tolerance was measured using a computerized behavioral distress tolerance task, the Computerized Paced Auditory Serial Addition Task (PASAT-C). Tobit regression analyses indicated a significant interaction between distress tolerance and depressive symptoms in predicting alcohol problems, such that depressive symptoms were significantly associated with problematic alcohol use among adults with low, but not high, distress tolerance. Thus, alcohol use interventions with a focus on distress tolerance skills in the context of depressive symptoms may be particularly effective.

Studies have shown a strong negative correlation between counterproductive work behaviour (CWB) and organizational citizenship behaviour (OCB), and opposite correlations with hypothesized antecedents. Such observed correlations may have been erroneously caused by three measurement artefacts: items measuring absence of CWBs, rather than behaviours that exceed requirements or expectations in OCB scales; supervisory halo; and agreement rather than frequency response format. A new OCB scale, the OCB‐checklist (OCB‐C) was used that did not have these artefacts. Contrary to prior expectations from the literature, positive relations were found between CWB and OCB, and stressors and OCB. Theoretical explanations for positive CWB/OCB relations (demand‐elicited OCB, social loafing, work process problems, rater perceptions and attributions, and aggravated job stress processes) are discussed. 相似文献
