Electron-energy-loss spectra have been recorded from cross-sectional transmission electron microscopy samples of Li + -irradiated KTiOPO 4 single crystals. By evaluating the intensity in the pre-edge shoulder of the OK ionization edge, the depth distribution of O vacancies in radiation-damaged KTiOPO 4 was monitored. Li + irradiation at 295K and Li + irradiation at 100K generate very similar defect profiles except for an additional superficial maximum in the room-temperature-irradiated sample. Vacancy distributions in the O sublattice can be monitored on the nanometre scale by the method introduced. The methodology is potentially applicable to a wide range of materials, when pertinent defect-sensitive features in electron-energy-loss spectra are evaluated, and its sensitivity is expected to become further improved with the availability of monochromated electron sources in transmission electron microscopes.  相似文献

An experimental study is reported which investigates the differences in interpretation between content conditionals (of various pragmatic types) and inferential conditionals. In a content conditional, the antecedent represents a requirement for the consequent to become true. In an inferential conditional, the antecedent functions as a premise and the consequent as the inferred conclusion from that premise. The linguistic difference between content and inferential conditionals is often neglected in reasoning experiments. This turns out to be unjustified, since we adduced evidence on the basis of a quantitative and a qualitative analysis that this difference has a manifest psychological relevance. For the inferential conditionals, participants appear to retrieve the order of events of the original content conditional on which it was based, before they start reasoning with it. The implications of this finding for reasoning research and linguistics will be discussed.  相似文献

It is widely acknowledged that encouraging walking in urban environments should be a major public health goal. This view is supported by many studies in environmental psychology, in particular those designed to identify characteristics of the urban environment that support and encourage healthy walking. This article proposes to translate the Irvine-Minnesota Inventory (IMI), a well-established instrument, carefully developed to measure the potential walkability of city districts and neighborhoods, and to adapt this tool to so that it captures the unique historic and cultural features of French cities while still retaining the items that have made it so useful in the United States. A new French/American version of the IMI was developed, comprising 203 items. This version was tested in neighborhoods in a mid-size French city and yielded very good internal and inter-judge reliability and good discrimination.  相似文献

This study investigated the moderating effect of achievement striving (AS) on the relationship between situational variables, defined by the Job Demand–Control model (JDC), and both work–family conflict and work–family facilitation. In a sample of 224 employees in the welfare sector, the results of two hierarchical regression analyses showed that job demands were significantly positively related and job control was significantly negatively related to work–family conflict but not to work–family facilitation. For AS, a significant positive relationship was found with both work–family conflict and work–family facilitation. Interactions between situational variables and AS were insignificant although the interaction between AS and job control on work–family facilitation was close to significance in line with the expectations. Specifically, a lower level of job control did not lower the level of WFF experienced by individuals high on AS. Theoretical and practical implications are discussed.  相似文献

Based on assumptions of the Job Demands–Resources model and the Person–Environment fit literature, the present research conceptualizes an intrinsic relative to an extrinsic work value orientation as a personal resource. We examine whether such an orientation may strengthen the relations of classical job resources (i.e., autonomy and learning opportunities) with well-being outcomes. The results in a large, representative sample of Dutch employees (N = 4009) show that a predominant intrinsic work orientation strengthened the negative association of learning opportunities with emotional exhaustion as well as the buffering role of autonomy for the health-impairing impact of workload. With respect to work engagement, a predominant intrinsic work orientation strengthened the positive association of autonomy, the expected boosting impact of workload on the stimulating association of autonomy, as well as the—rather unexpected—attenuating impact of workload on the positive association of learning opportunities with work engagement. Although not all hypotheses were confirmed, in general, results point at the importance and practical relevance of personal resources in the realm of the Job Demands–Resources model.  相似文献

The present study explores whether Karasek's Job Demand–Control (JDC) model's strain hypothesis can be applied to target's reports of bullying at work in matched samples of Spanish and Belgian blue-collar workers. In the Spanish sample, results reveal a positive main effect of workload and a negative main effect of autonomy. The relationship between workload and bullying is particularly strong under the condition of low autonomy (i.e., interaction), in line with Karasek's strain hypothesis. In the Belgian sample, results show a positive main effect of workload and a significant workload–autonomy interaction effect in accordance with the strain hypothesis. In sum, high strain jobs associate with target's reports of bullying in both the Spanish and Belgian sample. Karasek's JDC model may accordingly be extended to target's reports of bullying as a form of social behavioural strain. These findings furthermore enhance research in the realm of bullying at work by introducing a well-established theoretical framework to account for the relationship between workload, autonomy, and target's reports of bullying.  相似文献

We review the recent research literature on pro-criminal attitudes (PCAs) as a causal factor of recidivism with a focus on studies on the effectiveness of offender treatment programs targeting PCAs to prevent recidivism. The main conclusions that can be derived from the literature are: (1) the evidence supports the hypothesis that PCAs are related to reoffending; (2) most investigated offender treatment programs tend to reduce PCAs, although the general lack of adequate control group designs does not rule out alternative explanations for this reduction; and (3) there is no conclusive empirical evidence that intervention programs designed to reduce PCAs are effective in reducing recidivism. Empirical research in this area lacks the theoretical and methodological rigor to test causal models of the influence of treatment on reducing PCAs, and effects of PCAs on recidivism. Limitations of the empirical evidence are related to inadequate research designs and/or suboptimal data analysis strategies. Recommendations concerning optimized research designs and data analysis strategies that are likely to provide more conclusive evidence on the relation of PCAs, PCA treatment, and recidivism are given.  相似文献

It is well known that there is a lack of consensus about how to decide between competing and sometimes mutually contradictory theories, and how to integrate divergent concepts and theories. In view of this situation the IPA Project Committee on Conceptual Integration developed a method that allows comparison between different versions of concepts, their underlying theories and basic assumptions. Only when placed in a frame of reference can similarities and differences be seen in a methodically comprehensible and reproducible way. We used “enactment” to study the problems of comparing concepts systematically. Almost all psychoanalytic schools have developed a conceptualization of it. We made a sort of provisional canon of relevant papers we have chosen from the different schools. The five steps of our method for analyzing the concept of enactment will be presented. The first step is the history of the concept; the second the phenomenology; the third a methodological analysis of the construction of the concept. In order to compare different conceptualizations we must know the main dimensions of the meaning space of the concept, this is the fourth step. Finally, in step five we discuss if and to what extent an integration of the different versions of enactment is possible.  相似文献

Spruyt obtained an affective congruency effect in a valent/neutral categorisation task, which contrasts with the absence of such an effect in the same task that was reported by Werner and Rothermund. The crucial difference between the two studies is that Spruyt presented only valent primes, whereas Werner and Rothermund presented equal amounts of valent and neutral primes and targets in their experiments. Removing the neutral primes introduces a confound of affective matches with the required response. Affective congruency effects in Spruyt's study can be explained straightforwardly in terms of such an affective matching strategy. To demonstrate the influence of matching strategies in the valent/neutral task without neutral primes, we conducted an experiment in which we induced an affective mismatching strategy. In support of our reasoning, this study revealed an affective incongruency effect in the valent/neutral categorisation task. We conclude that affective congruency as well as incongruency effects in the valent/neutral categorisation task reflect post-lexical affective (mis-)matching strategies rather than encoding facilitation.  相似文献
