Numerous studies have shown the positive consequences of work engagement for both organisations and employees experiencing it. For instance, research has demonstrated that work‐engaged employees have lower levels of turnover intentions than non‐engaged employees. However, in this research, we examined whether there is a dark side of work engagement. More precisely, we investigated whether the relationship between work engagement and employees' turnover intentions might be non‐linear. Based on two different samples, our results indicated that the relationship between work engagement and employees' turnover intentions is curvilinear. The theoretical and practical implications of these results are discussed.  相似文献

Numerous studies have shown that perceived organizational support has positive consequences on both employees and organizations. However, no study has examined the causal relationship between perceived organizational support and proactive behaviour directed towards the organization and few studies have identified potential mechanisms underlying this relationship. We first investigated the direction of causality between perceived organizational support and proactive behaviour, and hypothesized that perceived organizational support leads to proactive behaviour directed towards the organization. Second, based on social exchange and motivational perspectives, we examined two potential mechanisms underlying this relationship, i.e., felt obligation and work engagement. Employees from a Belgian Federal Public Service were invited to take part in a three-wave longitudinal survey. Using a cross-lagged panel design, our results (N = 1963) revealed that Time 2 perceived organizational support was positively related to Time 3 proactive behaviour towards the organization, whereas the reverse was not true. Additionally, our results (N = 1293) showed that Time 2 felt obligation and Time 2 work engagement mediated the positive relationship between Time 1 perceived organizational support and Time 3 proactive behaviour directed towards the organization.  相似文献

Outside the cognitive psychologist's laboratory, problem-solving is an activity that takes place in a rich web of interactions involving people and artefacts. This interactivity is constituted by fine-grained action–perception cycles, and it allows a reasoner's comprehension of the problem to emerge from a coalition of internal and external resources. Taking an ecological approach to problem-solving, this paper introduces a qualitative method, Cognitive Event Analysis, for studying the fine-grained interactivity between a problem-solving agent and his/her environment. To demonstrate the potential of this method, it is used to study a single subject solving the so-called 17 Animals problem using a material model. The fine-grained procedure allows tracking the solution to a serendipity that was brought about because of the participant's aesthetic considerations and a change in her perceptual figure-ground configuration. While a qualitative single-case method cannot prove specific models of problem-solving, it questions prevalent mentalist models, and it generates new hypotheses on insight problem-solving, because it allows the researcher to attend to outliers and to variability on a fast and fine-grained between-measurement timescale.  相似文献

The variation in the structure of value trees can have undesirable effects on the attribute weights. Earlier experiments suggest that an attribute receives a higher weight if it is presented at an upper level in a value tree or if it is split into subattributes. Here we show that it is flawed to make conclusions about the biases at the individual level based on the averages of weights across large groups of subjects. Averages do not describe individual behavior. Furthermore, the averages of weights tend to approach even weights. By using the data from earlier experiments we illustrate how the averaging can produce different phenomena. We also show that the use of weights based on the rank order of attributes only can easily lead to biases when the structure of a value tree is changed. © 1998 John Wiley & Sons, Ltd.  相似文献

The acceptance of migrant populations and the definition of an “appropriate” migrant are controversial issues in many countries. The present research focuses on the ideological determinants of how newcomers are evaluated by a host population in a Western country with a strongly rooted meritocratic ideology. We carried out two studies to examine how the expression of meritocratic beliefs by a male potential migrant affects the way he is evaluated by the host population. We measured the host population's perception of the potential migrant's ability to integrate into society, his tendency to adopt the host country's culture, and the general desirability of his world vision for all newcomers. We also noted the host population's judgments of the target's agency and communality. The results showed that a potential newcomer who expresses a strong (vs. weak) belief in a just world (Study 1) or an internal (vs. external) locus of control (Study 2) is evaluated more favorably by the host population. In addition, judgments of the target's integration capacity were only mediated by his perceived agency. We discuss these results in the light of work on the meritocratic ideology and intercultural relations. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

We assessed whether certain life events contributed to the communication about cancer risk within families who have undergone BRCA1/2 testing. We also explored what type of resources participants would have valued to help in supporting family communication about genetic information. Two hundred and forty-six individuals (218 women, 28 men) who received a BRCA1/2 genetic test result 3 to 10 years earlier (mean of 6.4 years) participated in a telephone interview. Participants were asked about the occurrence of a number of life events (cancer diagnosis, death, uptake of prophylactic surgery, and providing care to a family member with cancer) in their family since their BRCA1/2 test result disclosure and, for each occurrence, whether it fostered family communication about cancer risk. A total of 182 participants (74 %) reported that they or one of their relatives received a cancer diagnosis, 176 (72 %) reported that someone died in their family, and 73 (30 %) stated that they or one of their relatives undertook a prophylactic surgery. During this period, 109 participants (44 %) also provided care for a family member who had cancer. Among participants who reported these life events, family communication was fostered by these events in proportions varying from 50 % (death) to 69 % (cancer diagnosis). Our results indicate that life events may contribute to family communication about cancer risk. Further research is needed to determine whether these events provide a “window of opportunity” to reach family members, address their needs and concerns about cancer, update family cancer history, and introduce genetic counseling and risk assessment.  相似文献

Insight problem solving was investigated with the matchstick algebra problems developed by Knoblich, Ohlsson, Haider, and Rhenius (1999 Knoblich, G., Ohlsson, S., Haider, H. and Rhenius, D. 1999. Constraint relaxation and chunk decomposition in insight problem solving. Journal of Experimental Psychology: Learning, Memory and Cognition, 25: 15341555. [Crossref], [Web of Science ®] [Google Scholar]). These problems are false equations expressed with Roman numerals that can be made true bymoving one matchstick. In a first group participants examined a static two-dimensional representation of the false algebraic expression and told the experimenter which matchstick should be moved. In a second group, participants interacted with a three-dimensional representation of the false equation. Success rates in the static group for different problem types replicated the pattern of data reported in Knoblich et al. (1999 Knoblich, G., Ohlsson, S., Haider, H. and Rhenius, D. 1999. Constraint relaxation and chunk decomposition in insight problem solving. Journal of Experimental Psychology: Learning, Memory and Cognition, 25: 15341555. [Crossref], [Web of Science ®] [Google Scholar]). However, participants in the interactive group were significantly more likely to achieve insight. Problem-solving success in the static group was best predicted by performance on a test of numeracy, whereas in the interactive group it was best predicted by performance on a test of visuo-spatial reasoning. Implications for process models of problem solving are discussed.  相似文献

In response to a mandate conferred on the International Bioethics Committee (IBC) of UNESCO in November 1993, the IBC has drafted a "universal declaration on the human genome and human rights," which will be considered by the General Conference of UNESCO in November 1997. This article discusses the development of the document and provides the text of the "revised preliminary draft" of the declaration.  相似文献
