The aim of the present study is to examine the mediating role of social safeness on the relationship between vengeance and life satisfaction. Participants were 305 university students who completed a questionnaire package which includes the Vengeance Scale, the Social Safeness and Pleasure Scale, and the Life Satisfaction Scale. According to the results, social safeness and life satisfaction were predicted negatively by vengeance. On the other hand, life satisfaction was predicted positively by social safeness. In addition, social safeness mediated the relationship between vengeance and life satisfaction. Together, the findings illuminate the social processes underlying the association of vengeance with life satisfaction. 相似文献

In this article we argue that the precautionary principle, as applied to the regulation of science and technology, cannot be considered in any general manner inconsistent with the norms and methods of scientific knowledge generation and justification. Moreover, it does not necessarily curtail scientific‐technological innovation. Our argument flows from a differentiated view of what precaution in regulation means. We first characterize several of the most relevant interpretations given to the precautionary principle in academic debate and regulatory practice. We then use examples of actual precaution‐based regulation to show that, even though science can have varying functions in different circumstances and frames, all of those interpretations recur to scientific method and knowledge, and tend to imply innovation in methods, products, and processes. In fact, the interplay of regulation and innovation in precautionary policy, at least in the case of the interpretations of precaution that our analysis takes into account, could be understood as a way of reconciling the two fundamental science and technology policy functions of promotion and control. 相似文献

Since it includes strong statistical and executive techniques, Six Sigma (SS) succeeded in many countries and different sectors. Especially successful SS applications of many international companies have increased the interest of other companies. As a result of this, the number of implemented SS projects in various countries has increased. Although successful SS projects are often in mind, the number of failed projects because of various reasons is not as low as to be ignored. As well as there are many factors that affect the success level of SS projects, and these factors vary according to countries. In this study, a survey was applied to 117 people who have 1 of SS belts in order to determine success levels of the SS projects in Turkey. By using explanatory factor analysis and structural equation modeling, critical success factors were determined. According to the results, project selection and its scope, quality culture and defining and measuring of metrics were determined as the top factors that are affecting success levels of SS projects applied in Turkey. The results of the study were also compared with the results of similar projects implemented in other countries. 相似文献

The aim of the paper is to demonstrate the appropriateness of an a priori analysis to determine the distributional assumption of the inefficiency term in a stochastic frontier model. To this end, theoretical distributions of estimated inefficiency were obtained when the inefficiency term is assumed to be distributed as a half normal and an exponential in a cost frontier model. Comparisons of such theoretical distributions with the respective cost inefficiency estimators using the goodness of fit test allow selecting the most appropriate distributional assumption. The application on three data sets of Spanish banking system in 2009 demonstrated the relevance of the research question. First, the results of estimated cost inefficiency with a half normal assumption are larger than with an exponential distribution significantly. Besides, half normal assumption was rejected and exponential was not rejected as the most appropriate distribution of inefficiency term in Spanish banking data set. However, the adjustment of saving banks data had been better with the former distribution than the latter. In the case of banks, any distribution results appropriate. To sum up, this work demonstrate that the distributional assumption on inefficiency term in Stochastic Frontier Approach must be established in a justified way, as it can significantly bias the results of estimated inefficiency and therefore, influences improving policies and strategies in the Spanish banking sector. 相似文献

Enclaves of like-minded people are often seen as problematic from a democratic point of view, as they have been found to lead to both group polarization and an amplification of cognitive errors. Nevertheless, enclaves can also act as protected spaces have the opportunity to discuss politics with their peers. As a result, people who are less well-endowed to face political disagreement can find it easier to engage in politics. In order to study the ‘empowering’ potential of enclave deliberation, we use data from a population-based experiment (n = 207). The participants were randomly allocated to two treatments. Some participants deliberated in groups consisting of people with similar baseline views on immigration (like-minded treatment), whereas others deliberated in groups where both restrictive and permissive participants were present (mixed treatment). We hypothesize that (1) discussion in like-minded groups is more equal than in mixed opinion groups and that (2) participants with lower resources feel politically more efficacious after deliberation in like-minded than in mixed groups. Our results suggest that people with higher resources tend to be more active regardless of treatment. Nevertheless, we also find that among those with lower resources deliberation in like-minded groups generates a higher sense of equality than discussion in mixed opinion groups. 相似文献

The aim of the current study was to investigate the influence of happy and sad mood on facial muscular reactions to emotional
facial expressions. Following film clips intended to induce happy and sad mood states, participants observed faces with happy,
sad, angry, and neutral expressions while their facial muscular reactions were recorded electromyografically. Results revealed
that after watching the happy clip participants showed congruent facial reactions to all emotional expressions, whereas watching
the sad clip led to a general reduction of facial muscular reactions. Results are discussed with respect to the information
processing style underlying the lack of mimicry in a sad mood state and also with respect to the consequences for social interactions
and for embodiment theories. 相似文献
