Time banditry has recently been introduced as a conceptually distinct construct in the counterproductive work behavior literature. An employee is engaged in time banditry if s/he pursues unsanctioned and/or unethical nonwork activities during work time. An analysis of the time banditry construct would be facilitated by the rigorous development of a measure of this construct. The purpose of this research was to develop and refine a multidimensional measure of time banditry. Items were generated through an extensive literature review and numerous workplace discussions with a diverse sample of employees. Through this process, we developed a 45‐item time banditry scale (Time Banditry Questionnaire; TBQ) and utilized it with a diverse sample. Exploratory and confirmatory factor analyses indicated that the construct of time banditry is multidimensional, exhibiting three distinct factors (classic, technology, and social). The TBQ demonstrated an internal consistency reliability of .90. Implications for the use of the TBQ in future research and application in organizations are discussed. The most salient suggestion in this study is that time banditry is more closely related to situational variables and personality variables than it is related to demographic variables.  相似文献

The neuropsychological functioning of 56 children and young adolescents with diagnoses of unipolar depression (n = 17), anxiety disorder (n = 19), or comorbid anxiety/depressive disorder (n = 20) was examined. The neuropsychological profiles of the three groups were parallel, but not equal in level of performance. The three groups displayed similar patterns of performance with profiles suggesting diminished attention abilities. The groups, however, were not equal in level of performance. While subjects with an anxiety or a depressive disorder were similar in level of performance, subjects with a comorbid anxiety/depressive disorder generally performed worse than those with either an anxiety or depressive disorder alone. There was no significant evidence of asymmetrical cerebral dysfunction in any of the diagnostic groups. Results are discussed in relation to adult models of psychopathology with an emphasis on the importance of considering developmental factors when formulating models of childhood psychopathology.  相似文献

Supportive supervision is doubtlessly beneficial in many instances in organizations. Paustian‐Underdahl, Shanock, Rogelberg, Scott, Justice, and Altman ( 2013 ) have examined the predictors of supportive supervision. We might suggest that they have underidentified those factors that impact the potential influence of supportive supervision and suggest a more comprehensive approach to this important variable.  相似文献

For each of 75 Ss several estimates of intra-individual variations were calculated for each of 4 motor skills. The reliability of intra-individual variation for these data, estimated from Pearson productmoment correlations, ranged from r = .31 to r = .51 (in all cases p < .05). It was also found that in 3 of the 4 skills, intra-individual variation correlated significantly (r = .36, .54, .55) with mean performance level. Second order partial correlations, holding constant the effect of mean performance level, were then used to estimate the reliability of intravariation. These correlations were statistically significant and ranged from r = .27 to r = .34. When correlations of intra-individual variation were calculated among the four skills it was demonstrated that intra-individual variation was approximately 95 to 100% task specific.  相似文献

The purpose of these experiments was to determine the effects of object weight and condition of weight presentation on the kinematics of human prehension. Subjects performed reaching and grasping movements to metal dowels whose visible characteristics were similar but whose weight varied (20, 55, 150, 410 g). Movements were performed under two conditions of weight presentation, random (weight unknown) and blocked (weight known). Three-dimensional movements of the thumb, index finger, and wrist were recorded, using a WATSMART system to obtain information regarding the grasp and transport components. The results of the first experiment indicated that object weight and condition of presentation affected the temporal and kinematic measures for both the grasp and transport components. In conjunction with the results of a second experiment, in which time in contact with the dowel was measured, it was shown that the free-motion phase of prehension (i.e., up to object contact) was invariant over the different conditions, however. The changes were observed in the finger-object interaction phase (when subjects applied forces after contact with the dowel), prior to lift-off. These results were interpreted as indicating (a) object weight does not influence the planning and execution of the free-motion phase of prehension and (b) there are at least two motor control phases involved in prehension, one for making contact with the object and the other for finger-object interaction. The changing contributions of visual, kinesthetic, and haptic information during these two phases is discussed.  相似文献

2 groups of 50 Ss practiced a pursuit rotor skill under different schedules of practice. A massed practice (MP) group (40 sec. work, 20 sec. rest) performed just as well as a distributed practice (DP) group (20 sec. work, 20 sec. rest) on the first day of practice. However, after 24 hr. of interpolated rest MP Ss demonstrated significantly greater amounts of learning. A further analysis of the 15 high initial ability and 15 low initial ability Ss from each of the two main groups resulted in no statistical differences among these subgroups in Day 1 performance that could be attributed to the practice schedules; however, a significant Ability Level × Practice Schedule interaction was obtained for Day 2 performance. It was caused by the low ability Ss under MP learning relatively more than the high ability Ss under MP when compared to the two DP groups. Thus learning was seen as being a function not only of schedule of practice but also of initial ability level.  相似文献

ObjectiveThe aim of the current study was to integrate recent developments in the retraining of attentional biases towards threat into a standard cognitive behavioural treatment package for social phobia.Method134 participants (M age – 32.4: 53% female) meeting DSM-IV criteria for social phobia received a 12-week cognitive behavioural treatment program. They were randomly allocated to receive on a daily basis using home practice, either an additional computerised probe procedure designed to train attentional resource allocation away from threat, or a placebo variant of this procedure. Measures included diagnostic severity, social anxiety symptoms, life interference, and depression as well as state anxiety in response to a laboratory social threat.ResultsAt the end of treatment there were no significant differences between groups in attentional bias towards threat or in treatment response (all p's > 0.05). Both groups showed similar and highly significant reductions in diagnostic severity, social anxiety symptoms, depression symptoms, and life interference at post-treatment that was maintained and in most cases increased at 6 month follow-up (uncontrolled effect sizes ranged from d = 0.34 to d = 1.90).ConclusionsThe current results do not indicate that integration of information processing-derived attentional bias modification procedures into standard treatment packages as conducted in this study augments attentional change or enhances treatment efficacy. Further refinement of bias modification techniques, and better methods of integrating them with conventional approaches, may be needed to produce better effects.  相似文献
