Temporal individual differences are an under-explored, but research-worthy form of diversity in teams. Although persistent differences in how members think about and value time can profoundly influence team performance, the compositional impact of time-based individual differences is regularly overlooked. Optimal or suboptimal team performance can result because the composition of time-based individual differences is matched or unmatched (respectively) to task demands. Therefore, we offer a detailed presentation of how the configuration of four time-based individual differences (time urgency, time perspective, polychronicity, and pacing style) interact with two task typologies (task type and task complexity) to specify when elevation (mean) and diversity (dispersion) of temporal differences is helpful or harmful to team performance. 相似文献

In the search for animal models of human geriatric depression, we found that operant extinction of escape from water results in the expression of immobility in different age groups, indicative of behavioral "despair", which was also associated with the resistance-to-extinction (RTE) expressed by these animals. With respect to the neurotrophin hypothesis of depression, nerve-growth factor (NGF), brain-derived neurotrophic factor (BDNF) and neurotrophin-3 (NT-3) protein levels in frontal cortex (FC) and hippocampus (HP) were examined and related to behavioral immobility and RTE in the water maze in aged and adult Wistar rats. Age-related increases in levels of NGF were found in HP and of NT-3 in FC. Indices of immobility showed relationships in the aged with NGF and, in adults, with BDNF, pointing to a dissociation of neurotrophic involvement in extinction trial-induced "despair" in aged and adult rats. The present results support the hypothesis, that extinction-induced immobility in the water maze reflects a state akin to behavioral despair and point to age-related differences of neurotrophic involvement in depressive-like symptoms. The concept of extinction-induced behavioral "despair" in the aged subsumes several aspects of human geriatric depression, such as co-morbidity of learning impairment and anxiety, and, thus could represent a useful paradigm to examine the neuronal mechanisms underlying depression, especially in aged rodents. 相似文献

In this article the issues of egg and embryo implantation are examined in the light of i&art1;ālat al-ibā&art2;a wa-al-&art2;īliyya in Shi&art12;ite teachings and the Kantian principle of autonomy. Textual justification is given for the ibā&art2;a doctrine that what is not explicitly prohibited is permissible. When applied to the issues of egg and embryo implantation this leads to the conclusion that people may freely decide whether or not to engage in these medical processes, taking into account other relevant norms and possible consequences. A similar conclusion is reached through discussion of three particular cases of egg and embryo implantation in the light of an interpretation of Kantian autonomy in which people freely use reason to make right decisions in accordance with universal moral law. Despite the major differences between the two systems several similarities are noted and it is suggested that constructive development could result from interaction between them. 相似文献

This paper will look at the Sufi interpretations of Sūrat al-fāti&art1;a found in the early mystical Qur'an commentary known as the &art2;aqā'iq al-tafsīr by the well known Sufi, Abū c Abd al-Ra&art1;mān al-Sulamī (d. 1021). The Sufi tafsīr of this sūra will be read not only as a compilation of early mystical interpretations of the Qur'an, but also as a unique work by Sulamī himself. A close reading of the various Sufi authors' interpretations set out by Sulamī will show how his own positions concerning the fundamental Sufi concept of macrifa come about. 相似文献

Environmental enrichment (EE) increases dentate gyrus (DG) neurogenesis and brain-derived neurotrophic factor (BDNF) levels. However, running is considered an element of EE. To dissociate effects of physical activity and enrichment on hippocampal neurogenesis and BDNF levels, young female C57Bl/6 mice were housed under control, running, enrichment, or enrichment plus running conditions, and injected with bromodeoxyuridine. Cell genesis was assessed after 12 d and differentiation was analyzed 1 mo later. In addition, locomotor activity in the open field and hippocampal mature BDNF peptide levels were measured. Open-field adaptation was improved in all groups, compared to controls, but more so with running. New cell proliferation, survival, neuron number, and neurotrophin levels were enhanced only when running was accessible. We conclude that exercise is the critical factor mediating increased BDNF levels and adult hippocampal neurogenesis. 相似文献

Correlational research investigating the relationship between scores on self-report imagery questionnaires and measures of social desirable responding has shown only a weak association. However, researchers have argued that this research may have underestimated the size of the relationship because it relied primarily on the Marlowe-Crowne scale (MC; Crowne & Marlowe, Journal of Consulting Psychology, 24, 349-354, 1960), which loads primarily on the least relevant form of social desirable responding for this particular context, the moralistic bias. Here we report the analysis of data correlating the Vividness of Visual Imagery Questionnaire (VVIQ; Marks, Journal of Mental Imagery, 19, 153-166, 1973) with the Balanced Inventory of Desirable Responding (BIDR; Paulhus, 2002) and the MC scale under anonymous testing conditions. The VVIQ correlated significantly with the Self-Deceptive Enhancement (SDE) and Agency Management (AM) BIDR subscales and with the MC. The largest correlation was with SDE. The ability of SDE to predict VVIQ scores was not significantly enhanced by adding either AM or MC. Correlations between the VVIQ and BIDR egoistic scales were larger when the BIDR was continuously rather than dichotomously scored. This analysis indicates that the relationship between self-reported imagery and social desirable responding is likely to be stronger than previously thought. 相似文献
