Social Factors of Work-Environment Creativity 总被引:2,自引:0,他引:2
The aim of this study was to investigate how work-environment creativity is related to the social factors of: organizational-culture
perceptions, employee participation, knowledge sharing, and procedural justice. Questionnaires were administered to 154 employees
of a government organization. Because the employees within a department worked in diverse teams and their work environments
may have varied, our analysis was conducted at the level of the individual. Hierarchical regression analyses showed that work-environment
creativity was related to adhocracy-culture perceptions, employee participation, and knowledge sharing; that knowledge sharing
was related to cooperative-team perceptions and procedural justice; and that knowledge sharing mediated the relationships
of cooperative-team perceptions and procedural justice with work-environment creativity. Practical implications of the results
are discussed. 相似文献

Driver distraction contributes to vehicle accidents, with estimates as high as one-half of crashes being distraction-related. The purpose of this experiment was to explore potential distractions by testing the effects of cellular telephone conversation and music listening on response time and its subcomponents of reaction time (RT) and movement time (MT) in a simulated braking task. Participants (N = 27) sat at a simulated driving station and released the accelerator and depressed the brake pedal as quickly as possible following activation of a simulated brake lamp. The braking task was performed under each of six conditions including: (a) the control (braking task only); (b) music playing at 66 dBA; (c) music playing at 78 dBA; (d) cellular telephone conversation; (e) cellular telephone conversation and music at 66 dBA; and (f) cellular telephone conversation and music at 78 dBA. Cellular telephone conversation slowed response time, yet music had no effect on response time. While the RT results generally mirrored those of response time (i.e., RT was also slowed by the telephone conversation), interestingly, MT was actually faster when the cellular telephone conversation was present compared to when it was not. Participants appear to have anticipated slower RT in the presence of the cellular telephone conversation, and attempted to compensate by executing a more rapid movement to the brake pedal. 相似文献

We examine the recent finding that neurons in spinal motor circuits enter a high conductance state during functional network
activity. The underlying concomitant increase in random inhibitory and excitatory synaptic activity leads to stochastic signal
processing. The possible advantages of this metabolically costly organization are analyzed by comparing with synaptically
less intense networks driven by the intrinsic response properties of the network neurons. 相似文献

In a population-based sample of 112 nine-year old twin pairs, we investigated the association among total brain volume, gray matter and white matter volume, intelligence as assessed by the Raven IQ test, verbal comprehension, perceptual organization and perceptual speed as assessed by the Wechsler Intelligence Scale for Children-III. Phenotypic correlations between the brain volumes and intelligence traits ranged between .20 and .33. Processing speed and brain volume did not correlate. The relation between brain volume and intelligence was entirely explained by a common set of genes influencing both sets of phenotypes. 相似文献

Previous studies indicate that when identifying individuals involved in bullying, the concordance between self- and peer- reports is low to moderate. There is support that self- and peer- identified victims constitute distinct types of victims and differ in adjustment. Likewise, differentiating between self- and peer- reports of bullying may also reveal distinct types of bullies. The goal of this study was to examine differences between types of bullies identified via dyadic nominations (self-identified, victim-identified, and self/victim identified). First, we examined the concordance between dyadic nominations of bullying and traditional measures of bullying (i.e., self- and peer-reports). Second, we compared the behavioral profiles of the bully types to nonbullies, with a focus on aggressive behaviors and social status. Third, we examined whether the types of bullies targeted victims with different levels of popularity, as well as the role of their own popularity and prioritizing of popularity. Participants were 1,008 Dutch adolescents (50.1% male, Mage = 14.14 years, standard deviation [SD] = 1.30) who completed a classroom assessment of dyadic nominations, peer nominations, and self-report items. Results indicated that victim identified and self/victim identified bullies were more aggressive, more popular, and less socially preferred than self-identified bullies and nonbullies. Self/victim identified bullies targeted victims with the highest social status. The association between bully type and victims' popularity was further qualified by bullies' own popularity and the degree to which they prioritized popularity. Implications for the implementation of dyadic nominations are discussed. 相似文献

The factor structure of health locus of control (Form A; K. A. Wallston, B. S. Wallston, & R. DeVellis, 1978) was examined in 420 octogenarians (M age = 83.2 years), and the contributions of genetic and environmental factors to health-control beliefs in 141 octogenarian twin pairs (71 identical, 70 same-sex fraternal) were estimated. Factor analyses reproduced previously proposed factors (Internal, Chance, and Powerful Others). Associations between health-control beliefs and life satisfaction, depression, and other health-related measures (e.g., self-rated health, outpatient contacts, and hospitalization), were modest. Quantitative genetic analyses revealed significant shared environmental influence on the Chance subscale, and significant familiality (attributable to a combination of genetic and shared environmental influences) on the Powerful Others subscale; there was no evidence of familiality on the Internal subscale. 相似文献

On assiste dans le domaine du développement des ressources humaines à un passage de l’optique formation à la perspective apprentissage. La formation est de plus en plus perçue comme seulement l’une des solutions disponibles pour mettre en place les processus d’apprentissage dans les organisations de travail, et pas toujours comme étant la plus efficace. Les autres formes d’apprentissage ont pris beaucoup d’importance dans la dernière décennie, en particulier celles étroitement reliées au travail quotidien, sur le lieu de travail et dans le cadre élargi de la culture organisationnelle qui devient un puissant outil d’apprentissage. Après avoir retracé l’histoire du passage de la formation à l’apprentissage, l’article propose trois orientations pour de futures investigations: le travail comme facteur potential d’apprentissage, l’apprentissage sur le lieu de travail et les environnements formateurs. A l’intérieur de chacun de ces thèmes, on analyse d’éventuelles pistes de recherche et quelques problématiques stimulantes sont présentées. The field of human resource development is in the process of shifting from a training to a learning orientation. Increasingly, training is viewed as just one possible way to organise learning processes in work organisations, and not always the most effective one. Other ways of organising learning processes have gained much interest in the last decade, particularly those closely related to everyday work, in the context of the workplace, and in the broader organisational culture as a powerful learning environment. After explaining the history of the shift from training to learning, the article proposes three domains for further research: (1) the learning potential of work, (2) learning in the workplace, and (3) learning environments. Within each of these themes, possible research avenues are discussed and some challenging research questions are put forward. 相似文献

Spirituality is an important theme in health research, since a spiritual orientation can help people to cope with the consequences of a serious disease. Knowledge on the role of spirituality is, however, limited, as most research is based on measures of religiosity rather than spirituality. A questionnaire that transcends specific beliefs is a prerequisite for quantifying the importance of spirituality among people who adhere to a religion or none at all. In this review, we discuss ten questionnaires that address spirituality as a universal human experience. Questionnaires are evaluated with regard to psychometric properties, item formulation and confusion with well-being and distress. Although none of the questionnaires fulfilled all the criteria, the multidimensional Spiritual Well-Being Questionnaire is promising. 相似文献

In Experiment 1, 4 pigeons were trained on a multiple chain schedule in which the initial link was a variable-interval (VI) 20-s schedule signalled by a red or green center key, and terminal links required four responses made to the left (L) and/or right (R) keys. In the REPEAT component, signalled by red keylights, only LRLR terminal-link response sequences were reinforced, while in the VARY component, signalled by green keylights, terminal-link response sequences were reinforced if they satisfied a variability criterion. The reinforcer rate for both components was equated by adjusting the reinforcer probability for correct REPEAT sequences across sessions. Results showed that initial- and terminal-link responding in the VARY component was generally more resistant to prefeeding, extinction, and response-independent food than responding in the REPEAT component. In Experiment 2, the REPEAT and VARY contingencies were arranged as terminal links of a concurrent chain and the relative reinforcer rate was manipulated across conditions. For all pigeons, initial-link response allocation was biased toward the alternative associated with the VARY terminal link. These results replicate previous reports that operant variation is more resistant to change than operant repetition (Doughty & Lattal, 2001), and show that variation is preferred to repetition with reinforcer-related variables controlled. Behavioral momentum theory (Nevin & Grace, 2000) predicts the covariation of preference and resistance to change in Experiments 1 and 2, but does not explain why these aspects of behavior should depend on contingencies that require repetition or variation. 相似文献
