Drawing on the theoretical framework of social cognitive theory, our study explores the multilevel mediation model in which moral disengagement (level-1) mediates the direct relationships between knowledge hiding by supervisors from subordinates (KHSS: level-2) and supervisor directed organizational citizenship behavior (SOCB: level-1) and supervisor directed silence (SS: level-1). Drawing on multi-sourced, multi-timed, and multilevel data of 306 subordinates nested within 83 supervisors, multilevel structural equation modeling (ML-SEM) was used to test the proposed model. The results demonstrate that KHSS, first, fosters subordinates’ moral disengagement, which in turn reduces their SOCB and enhances their SS. Our findings offer several useful theoretical and managerial implications of the negative consequences of supervisor knowledge hiding in organizations. As one of the first studies to provide empirical evidence for the existence of supervisor knowledge hiding (i.e. KHSS), this research highlights the consequences of KHSS on subordinates’ moral disengagement, SOCB, and SS. 相似文献

The effects of dopaminergic drugs on morphine state-dependent memory of passive avoidance task were examined in mice. Pre-training administration of morphine (5mg/kg) led to state-dependent learning with impaired memory retrieval on the test day which was reversed by pre-test administration of the same dose of the opiate. The pre-test intracerebroventricular (i.c.v.) administration of the dopamine D1 receptor agonist (SKF38393), dopamine D2 receptor agonist (quinpirole) and dopamine D2 receptor antagonist (sulpiride) not only reversed the effect of pre-training morphine treatment, but also increased this action of the drug. Furthermore, the pre-test i.c.v. administration of dopamine D1 receptor antagonist (SCH23390) prevented the restoration of memory by morphine. In conclusion, the morphine-induced recovery of memory, on the test day, seems to be induced, at least in part, through dopamine receptors. 相似文献

There is growing evidence that Internet-mediated psychological tests can have satisfactory psychometric properties and can
measure the same constructs as traditional versions. However, equivalence cannot be taken for granted. The prospective memory
questionnaire (PMQ; Hannon, Adams, Harrington, Fries-Dias, & Gibson, 1995) was used in an on-line study exploring links between
drug use and memory (Rodgers et al., 2003). The PMQ has four factor-analytically derived subscales. In a large (N763) sample
tested via the Internet, only two factors could be recovered; the other two subscales were essentially meaningless. This demonstration
of nonequivalence underlines the importance of on-line test validation. Without examination of its psychometric properties,
one cannot be sure that a test administered via the Internet actually measures the intended construct. 相似文献

Romanians suffered incredible deprivations of every sort during the decades of Communist dictatorship. Most of the country’s
1,000 psychiatrists, and most of their patients, were victimized by the political system. A few psychiatrists actively engaged
in practices amounting to torture. Many, however, became willing or unwilling participants in the political abuse of their
profession.
Such political abuses were fostered by abusive legislation and abusive law enforcement by the secret police. Abuses included:
mass detentions in psychiatric hospitals of dissidents and political undesirables; abusive interpretation of the laws in detaining
persons not suffering from mental illness; false, politically motivated diagnoses and treatment; and detention in secret facilities. 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

Since Kahneman and Tversky [(1979). Prospect theory: An analysis of decision under risk. Econometrica, 47, 263-291], it has been generally recognized that decision makers overweight low probabilities. Of the several weighting functions that have been proposed, that of Prelec [(1998). The probability weighting function. Econometrica, 60, 497-528] has the attractions that it is parsimonious, consistent with much of the available empirical evidence and has an axiomatic foundation. Luce [(2001). Reduction invariance and Prelec's weighting functions. Journal of Mathematical Psychology, 45, 167-179] provided a simpler derivation based on reduction invariance, rather than compound invariance of Prelec [(1998). The probability weighting function. Econometrica, 60, 497-528]. This note introduces a behavioral assumption that we call power invariance and provides a simple derivation of Prelec's function. Thus, we have three a priori different behavioral assumptions all leading to Prelec's function. 相似文献

In “Compassionate Phenomenal Conservatism” (2007), “Phenomenal Conservatism and the Internalist Intuition” (2006), and Skepticism and the Veil of Perception (2001), Michael Huemer endorses the principle of phenomenal conservatism, according to which appearances or seemings constitute a fundamental source of (defeasible) justification for belief. He claims that those who deny phenomenal conservatism, including classical foundationalists, are in a self-defeating position, for their views cannot be both true and justified; that classical foundationalists have difficulty accommodating false introspective beliefs; and that phenomenal conservatism is most faithful to the central internalist intuition. I argue that Huemer’s self-defeat argument fails, that classical foundationalism is able to accommodate fallible introspective beliefs, and that classical foundationalism has no difficulty accommodating a relatively clear internalist intuition. I also show that the motivation for phenomenal conservatism is less than clear. 相似文献

Partai Keadilan Sejahtera (PKS, The Justice and Prosperity Party) is the largest Islamist political party in Indonesia. It has roots in the religious and political and religious teachings of the Muslim Brotherhood and promotes what Oliver Roy calls "deculturized religion." The party can be understood as the political component of a larger social movement that seeks to transform Indonesian society and culture in ways that would establish Shari'ah as social, if not political, reality. It is also committed to the electoral process and to working inside the Indonesian political system in a more general sense. Until recently, the PKS has dismissed local modes of Muslim practice and much of Indonesian culture as "un-Islamic." The extent of the party's transformative agenda is unclear for three reasons: it shares the Muslim Brotherhood's gradualist approach, it is less than transparent about its goals, and it is divided into purist or "Justice" and pragmatic or "Prosperity" factions. The leadership of the Prosperity faction is currently ascendant and is attempting to reach beyond its Islamist base by sponsoring musical and dramatic performances it hopes will appeal to Muslims devoted to Javanese and other Indonesian cultural traditions. Ethnographic and web-based research indicate that these efforts are greeted with considerable suspicion. 相似文献
