Teams make it work: how team work engagement mediates between social resources and performance in teams 总被引:1,自引:0,他引:1
In this study we analyze the mediating role of team work engagement between team social resources (i.e., supportive team climate, coordination, teamwork), and team performance (i.e., in-role and extra-role performance) as predicted by the Job Demands-Resources Model. Aggregated data of 533 employees nested within 62 teams and 13 organizations were used, whereas team performance was assessed by supervisor ratings. Structural equation modeling revealed that, as expected, team work engagement plays a mediating role between social resources perceived at the team level and team performance as assessed by the supervisor. 相似文献

Taking the Resources-Experiences-Demands Model (RED Model) by Salanova and colleagues as our starting point, we tested how work self-efficacy relates positively to negative (i.e., work overload and work-family conflict) and positive outcomes (i.e., job satisfaction and organizational commitment), through the mediating role of workaholism (health impairment process) and work engagement (motivational process). In a sample of 386 administrative staff from a Spanish University (65% women), Structural Equation Modeling provided full evidence for the research model. In addition, Multivariate Analyses of Variance showed that self-efficacy was only related positively to one of the two dimensions of workaholism, namely, working excessively. Finally, we discuss the theoretical and practical contributions in terms of the RED Model. 相似文献

Emotion over‐regulation in infancy has seldom been the focus of empirical research. This study analysed the specificities of over‐regulation when compared with under‐regulation (maladaptive) and adaptive regulation by testing its association with attachment, dyadic emotional interaction, and temperament. The sample consisted of 52 low‐risk mother–infant dyads. During a home visit, dyadic emotional interaction was assessed in the daily routines and free play of 10‐month‐old infants. The infant's emotion regulation was assessed using the Shape Sorter Task, and a temperament questionnaire was completed by the mother. Attachment was assessed at 12 or 16 months using the Strange Situation. As hypothesized, (i) emotion over‐regulation (versus adaptive regulation) was predicted by a lower quality of dyadic emotional interaction and marginally by avoidant attachment; (ii) over‐regulation (versus under‐regulation) was predicted by avoidant attachment; and (iii) the predictive role of avoidant attachment was substantiated after controlling for another measure of mother–infant interaction. Contrary to expectations, temperament did not distinguish between emotion regulation styles. The link between over‐regulation and lower quality of mother–infant emotional interaction and avoidant attachment was demonstrated. There is empirical support to the claim that it is possible to identify emotion over‐regulation in infancy and that it is a maladaptive style of emotion regulation.

In this study, event related potentials (ERPs) were used to investigate the extent to which dyslexics (aged 9-13 years) differ from normally reading controls in early ERPs, which reflect prelexical orthographic processing, and in late ERPs, which reflect implicit phonological processing. The participants performed an implicit reading task, which was manipulated in terms of letter-specific processing, orthographic familiarity, and phonological structure. Comparing consonant- and symbol sequences, the results showed significant differences in the P1 and N1 waveforms in the control but not in the dyslexic group. The reduced P1 and N1 effects in pre-adolescent children with dyslexia suggest a lack of visual specialization for letter-processing. The P1 and N1 components were not sensitive to the familiar vs. less familiar orthographic sequence contrast. The amplitude of the later N320 component was larger for phonologically legal (pseudowords) compared to illegal (consonant sequences) items in both controls and dyslexics. However, the topographic differences showed that the controls were more left-lateralized than the dyslexics. We suggest that the development of the mechanisms that support literacy skills in dyslexics is both delayed and follows a non-normal developmental path. This contributes to the hemispheric differences observed and might reflect a compensatory mechanism in dyslexics. 相似文献

OFA hr/hr (OFA) rats present a major lactation deficit that impairs offspring survival. To explore whether abnormal stress responsiveness causes this deficit, we compared their hormonal (prolactin, progesterone, and corticosterone) responses to stress (room change and 2-min ether exposure) with those of Wistar and Sprague Dawley (SD) rats. We tested responses during the estrous cycle, pregnancy, lactation, after ovariectomy, and ovarian steroid hormone priming, and responses to suckling. We evaluated hypothalamic expression of receptors for prolactin (PRLRlong) and the isoforms of receptors for progesterone (PRA and B) and estrogen (ERα and β) in late pregnancy. We tested whether administration of an anxiolytic (diazepam) improved lactation. Ether exposure increased circulating levels of the three hormones in the three strains of rats, cycling and ovariectomized, but was less effective in pregnancy and lactation. Elevated estrogen level (estrus and estradiol-treated ovariectomized rats) potentiated the prolactin response more in SD and OFA rats than in Wistar rats. Elevated progesterone level (late pregnancy, lactation, progesterone-treated ovariectomized rats) inhibited the prolactin response less in OFA than in SD or Wistar rats. Ether exposure inhibited the prolactin and oxytocin responses to suckling only in OFA rats. Diazepam treatment increased pup survival rate and the prolactin response to suckling. Hypothalamic total PR mRNA content, assayed by RT-PCR, was higher in pregnant OFA rats compared with SD and Wistar rats, but the PRB/PRA protein ratio determined by Western blot was lowest in Wistar rats, intermediate in OFA rats, and highest in SD rats. The heightened sensitivity to stress of lactating OFA rats may contribute to their lactational deficit and be caused by a combination of hypoprolactinemia and reduced inhibitory capacity of progesterone. 相似文献

This longitudinal study presents the first examination of the relation between hope, spirituality, religious practice and life satisfaction of students in Portugal. A sample of 227 adolescents aged 15–19 completed the Portuguese versions of the Children Hope Scale, Students’ Life Satisfaction Scale and a single item for each spirituality and religious practice variable. The results from the cross-sectional and longitudinal analyses suggest that hope and spirituality, but not religious practice, were strongly linked to adolescents’ life satisfaction. Hope significantly predicted life satisfaction at a single time point, 6-months and 1-year later, and spirituality scores added significant variance beyond hope scores. All the variables demonstrate moderate to high stability across 6-months and 1-year time frame; no significant changes were found between the variables across the administrations. These results parallel recent studies of adult and child life satisfaction and suggest strategies to promote life satisfaction in adolescents. 相似文献

RESUMENEs este un artículo dedicado a la capacidad metalingüística, en la compresión de lenguaje, en el que se precisan algunas de las ideas de anteriores trabajos, sobre la génesis de la capacidad metalingüística del niño. Se basa el trabajo en la necesidad de emplear claves contextuales en las funciones de compresión (de la distinción sujeto-objeto, en este caso). La investigación presentada permite establecer varios niveles en las estrategias de compresión y captación de errores lingüísticos, centrándose especialmente en un nivel “intermedio” de desarrollo de la competencia metalingüística, caracterizado por respuestas oscilatorias entre los niños que requieren claves contextuales (aunque sean internas) para permitir la comprensión y aquellos otros, de nivel “formal”, en que dichas claves ya no son necesarias y de una captación consistente de los errores lingüísticos. 相似文献

The increasingly pluralistic character of modern societies has led to questions, not only about the proper use of ethnic-group terms, but also about the correct semantic analysis of them. Here I argue that ethnic-group terms are analogous to other linguistic expressions whose extension is fixed in the way suggested by a causal theory of reference. My view accommodates precisely those scenarios of communication involving ethnic-group terms that will be seen puzzling to Fregeans. At the same time, it undermines the plausibility of skepticism about those terms. 相似文献
