Parenting style and smoking-related cognitions have both successfully predicted adolescent smoking behaviour. Data were collected among 482 Dutch adolescents to examine whether effects of parenting styles (authoritative, permissive, authoritarian, rejecting, neglecting, measured by underlying dimensions support, strict control, and psychological control) on adolescent lifetime smoking were mediated by cognitions (pro-smoking attitude, social norm, self-efficacy, intention) and to study the role of gender in this process. Support was not significantly associated with smoking behaviour. The inverse relation between strict control and smoking was partly mediated by attitude and intention, both associated with increased smoking. Psychological control related directly to increased lifetime smoking. Combinations of dimensions creating the specific styles were not associated with cognitions or behaviour. Maternal and paternal parenting were equally associated with smoking cognitions and behaviour; nor were effects moderated by adolescent gender. Interventions to prevent adolescent smoking initiation should aim at increasing strict control and reducing psychological control.  相似文献

This longitudinal study examined whether habit strength moderates the intention–physical activity (PA) relationship in older adults, within the framework of the attitude–social influences–efficacy (ASE) model and the theory of planned behaviour (TPB). A total of 1836 older adults (M age?=?62.95?years, SD age?=?8.17) completed a questionnaire on social cognitive constructs and PA habit strength at baseline, and six?months later a measure of PA. Three PA habit groups (i.e. low, medium and high) were composed, based on tertiles of the mean index score. Multi-group structural equation modelling analyses showed that intention significantly determined PA behaviour only in participants with a low or medium habit strength towards PA. This result suggests that PA is not intentional at high levels of habit strength and demonstrates the usefulness of incorporating habit in the ASE and TPB models. Results also showed that about half of the participants with a strong PA habit did not meet the recommended PA level. As strong habits may prevent intentional behavioural change and may hinder the receptiveness and openness for informational PA change strategies, additional intervention strategies, such as awareness raising and the use of implementation intentions, are needed for strongly habitual, but insufficiently active older adults.  相似文献

This individual differences study examined the relationships between three executive functions (updating, shifting, and inhibition), measured as latent variables, and performance on two cognitively demanding subtests of the Adult Decision Making Competence battery: Applying Decision Rules and Consistency in Risk Perception. Structural equation modelling showed that executive functions contribute differentially to performance in these two tasks, with Applying Decision Rules being mainly related to inhibition and Consistency in Risk Perception mainly associated to shifting. The results suggest that the successful application of decision rules requires the capacity to selectively focus attention and inhibit irrelevant (or no more relevant) stimuli. They also suggest that consistency in risk perception depends on the ability to shift between judgement contexts.  相似文献

It has been suggested that numerically male-dominated workplaces propagate cultural norms that support sexual bravado, sexual posturing, and the denigration of feminine behaviour (Sbraga & O'Donohue, 2000 Sbraga, T. P. and O'Donohue, W. 2000. Sexual harassment. Annual Review of Sex Research, 11: 258285. [Taylor & Francis Online] [Google Scholar]). These cultural norms are features of normative male dominance, which have been shown to increase the risk of sexual harassment. This implies that the effect of numerical male dominance on sexual harassment may be mediated by the level of normative male dominance in the work environment. The aim of this study was to test this assumption. Our sample consisted of 1295 police women, who filled out an Internet questionnaire. The results suggest that normative male dominance indeed mediates the relation between numerical male dominance and sexual harassment. We add to the sexual harassment literature by building on Gruber's concept of double dominance. Our study helps to make clear why women are at greater risk of sexual harassment in work situations where men outnumber women than in more gender-balanced workplaces.  相似文献

Managerial derailment is costly to managers, their co-workers, and their organization. Knowing whether discrepancies (i.e., differences, dissimilarity, disagreement, incongruity) exist between self- and observer- (subordinates, peers, and bosses) ratings about derailment may help to lessen or prevent the detrimental outcomes of derailment on managers, their co-workers, and their organization. Results from 1742 European managers revealed a statistically significant difference between a manager's self-ratings and observer-ratings on the extent to which a manager displayed derailment behaviours and characteristics. The discrepancy also widened as managerial level increased, and was mostly due to inflated self-ratings. In addition, discrepancies between self – boss, self – direct report, and self – peer were examined, as well as differences between European and American managers. A discussion of these findings and implications for practice conclude this article.  相似文献

This study tests whether cognitive failures mediate effects of work-related time pressure and time control on commuting accidents and near-accidents. Participants were 83 employees (56% female) who each commuted between their regular place of residence and place of work using vehicles. The Workplace Cognitive Failure Scale (WCFS) asked for the frequency of failure in memory function, failure in attention regulation, and failure in action execution. Time pressure and time control at work were assessed by the Instrument for Stress Oriented Task Analysis (ISTA). Commuting accidents in the last 12 months were reported by 10% of participants, and half of the sample reported commuting near-accidents in the last 4 weeks. Cognitive failure significantly mediated the influence of time pressure at work on near-accidents even when age, gender, neuroticism, conscientiousness, commuting duration, commuting distance, and time pressure during commuting were controlled for. Time control was negatively related to cognitive failure and neuroticism, but no association with commuting accidents or near-accidents was found. Time pressure at work is likely to increase cognitive load. Time pressure might, therefore, increase cognitive failures during work and also during commuting. Hence, time pressure at work can decrease commuting safety. The result suggests a reduction of time pressure at work should improve commuting safety.  相似文献

Abstract

The paper argues that residential projects working mainly with those diagnosed schizophrenic are specialized work groups, in Bion's terms, operating upon the assumption of pairing, and illustrates this with reference to a period of organizational change at one such project. The reasons why this might be so are discussed, and are related to the central issue of hope and despair in work with those who are unlikely to recover.  相似文献

The influence of the mode of presentation (simultaneous vs. sequential) on accuracy and latency of visuospatial recognition was explored in three experiments. In Experiment 1, two groups were administered a visuospatial task in which a number of positions were shown either simultaneously or sequentially (in a random order); memory was tested using a recognition procedure of visuospatial patterns, either identical or different (a single cell displaced). The results showed that (1) performance was higher in the simultaneous than in the sequential presentation, and (2) decision time increased with complexity in the sequential presentation but not in the simultaneous presentation. In Experiment 2, the same task was used in three conditions of presentation, simultaneous, random sequential, and ordered sequential; at test, a single location, rather than a pattern, was presented for recognition. The results showed that (1) performance was higher in the simultaneous and in the ordered sequential presentations than in the random sequential one, and (2) decision time increased with complexity. In Experiment 3, the same task was used in the same three conditions of presentation, simultaneous, random sequential, and ordered sequential; at test either an identical or a “displaced” pattern was presented for recognition. The results showed that (1) performance was equivalent in the three types of presentation, and (2) decision time increased with complexity for “hit” items; different patterns of linear relations were observed for “correct rejections” items. The results are interpreted in terms of the organisation of visuospatial working memory, and three types of encoding—extrafigural spatial encoding, visual pattern encoding, and spatial path encoding—were proposed.  相似文献

Increasing police patrolling is often assumed to be an effective means of enhancing general feelings of safety. This relationship between perceiving police and feelings of safety was tested by having police officers patrol during a field experiment (Study 1) and by manipulating the police presence in pictures of neighborhoods in a laboratory experiment (Study 2). Both studies show that in environments that are generally considered to be safe, feelings of safety are not increased by police presence. Moreover, men feel less safe when police are present compared with when police are absent. The results are discussed in terms of possible underlying mechanisms and implications for police patrolling.  相似文献
