This study links idiosyncratic deals (i-deals) to job design theory. It investigates the impact of individually negotiated job changes on performance, self-efficacy, and psychological strain through their intervening effects on work design. Based on a sample of 187 health care professionals employed by a hospital in Germany, three types of work design-related i-deals were investigated: (1) task, (2) career, and (3) flexibility i-deals. Consistent with hypotheses, the three types of i-deal had differential effects on work characteristics, and each in turn related to different outcomes. Specifically, job autonomy mediated the task i-deals—job performance relationship; skill acquisition mediated the career i-deals—occupational self-efficacy relationship; and reduced work overload mediated the flexibility i-deals—emotional and affective irritation relationships. Leader–Member Exchange was confirmed as an antecedent of all three types of i-deals. Task, career, and flexibility i-deals are discussed as ways to make work more intrinsically motivating, ensure one’s professional advancement, and balance workplace stressors.  相似文献

This paper is written from a perspective that is sympathetic to the basic idea of the capability approach. Our aim is to compare Martha Nussbaum’s capability theory of justice with Alan Gewirth’s moral theory, on two points: the selection and the justification of a list of central capabilities. On both counts, we contend that Nussbaum’s theory suffers from flaws that Gewirth’s theory may help to remedy. First, we argue that her notion of a (dignified) human life cannot fulfill the role of a normative criterion that Nussbaum wants it to play in selecting capabilities for her list. Second, we question whether Nussbaum’s method of justification is adequate, discussing both her earlier self-validating argumentative strategy and her more recent adherence to the device of an overlapping consensus. We conclude that both strategies fail to provide the capabilities theory with the firm foundation it requires. Next, we turn to Gewirth’s normative theory and discuss how it can repair these flaws. We show how his theory starts from a fundamental moral principle according to which all agents have rights to the protection of the necessary preconditions of their agency. Gewirth’s justification of this principle is then presented, using a version of a transcendental argument. Finally, we explicitly compare Nussbaum and Gewirth and briefly demonstrate what it would mean for Nussbaum to incorporate Gewirthian elements into her capabilities theory of justice.  相似文献

Cognitive flexibility is one of the essential mental abilities underlying creative thinking. Previous findings have shown that cognitive flexibility can be enhanced by schema violations, and it has been suggested that active involvement is needed for schema violations to facilitate cognitive flexibility. The possibility that identification with an actor performing a schema violation (i.e., corepresenting an active schema violation) can enhance cognitive flexibility was investigated in 2 studies. In the first study, under conditions of high or low identification, participants watched an actor preparing a sandwich. The way the actor made the sandwich followed either a schema violation or contained the normal schema of preparing a sandwich. When identification was high, watching a schema-violation-enhanced cognitive flexibility as compared to watching the corresponding normal event. No effect of schema violation occurred under conditions of low identification. As little is known about the neural correlates of schema violations, in the second study the brain activity during schema violations was explored by means of functional Magnetic Resonance Imaging (fMRI). Participants were instructed to identify with an actor and brain activity was measured while participants watched the actor performing a schema violation or the corresponding normal schema. Activity in the temporal parietal junction (TPJ), a brain region that is associated with violation of expectations, was higher in the schema-violation condition than in the normal schema condition. These findings enhance the theoretical understanding of the effects of schema violations and may provide important practical implications in various settings where creative thinking is needed.  相似文献

The purpose of this research was to study the creative process in real-life settings and in a multicomponential perspective of creativity. Relations between the creative process and other important variables (mood, personality, and the creative product) were investigated. The data analyzed were collected in four applied art schools (n = 41) in Switzerland, during mandatory workshops. The creative process was operationalized through 2 subprocesses: generation (idea production) and selection (idea evaluation), both repeatedly measured across the workshops. The trajectories of theses subprocesses were modeled with a commonly used statistical model for longitudinal data (Latent Growth Models). Results showed that generation had an overall decreasing pattern through time, whereas selection had an inverted U-shaped pattern. Important individual differences in both subprocesses and related variables were also found, many of which had strong predictive validity. Indeed, process and personality variables explained 70% of the variance of the evaluation of the final product.  相似文献

In Turkey, the rate of consanguineous marriage is quite high (22–24 %) and as a result, the incidence of autosomal recessive diseases and congenital anomalies is also very high and gives rise to a serious public health problem. In the last three decades, great effort has been made to avoid increases in the prevalence of these hereditary diseases. For this purpose, population-based premarital, prenatal, neonatal and adult genetic screening programs are performed in various centers such as Community Health Centers, Early Diagnosis of Cancer and Education Centers (KETEM), Prenatal and Neonatal Departments of Universities and State Hospitals and Thalessemia Screening Centers. Such centers are staffed by health professionals including physicians, family physicians, nurses, midwives, biologists and medical geneticists. Genetic counseling is also provided to patients attending these centers after screening tests are performed. Since there are no specialized training programs for genetic counselors, genetic counseling is generally provided by doctors or medical geneticists. The aim of this paper is to give an overview of the genetic screening services provided in Turkey, the prevalence of genetic diseases and the design of intensive educational programs for health professionals.  相似文献

Abstract

Psychological responses to the nuclear accident in Chernobyl were assessed in several self-report inventories once a year from May 1986 until May 1991. Independent groups of subjects, divided according to sex and age (18–39 versus 40–59 years) were examined at six points in time for the subjective effects of the nuclear accident. The inventories included items related to attitudes, behavior, emotional states and coping styles. The results showed a generally greater emotional concern for women and for younger people. The findings also suggest that the psychological effects of the nuclear accident are long lasting.  相似文献

Abstract

The hypothesis that domain-specific self-related cognitions (self-concept of own competence and control orientations) are predictors of text anxiety in students is tested by longitudinal data. At the beginning and at the end of a school year the following variables were measured twice in a sample of 346 secondary school students (grades six to ten): (1) self-concept of own competence in mathematics, (2) three aspects of locus of control for problem-solving behavior (internality, powerful others control, and chance control), (3) generalized locus of control of reinforcement, (4) test anxiety as well as manifest anxiety. The cross-sequential developmental gradients point toward symmetries in the development of self-related cognitions and test anxiety. The results of cross-lagged correlation analyses show that the null hypothesis (no causal relations exist between the self-related cognitions and test anxiety) can be rejected for the domain-specific aspects of (a low) self-concept of own competence and locus of control (low internality and high chance control), which are confirmed as preceding test anxiety. However, longitudinal results also show that findings of cross-sectional studies tend to overestimate the relations between self-related cognitions and test anxiety in a developmental perspective.  相似文献
