Clinical reports suggest that fatigue is a common and disruptive long-term side effect of radiotherapy; however, there has been little systematic attention given to this phenomenon. The primary aim of this study was to assess fatigue its impact on quality of life in women who had completed radiotherapy for breast cancer. A key feature of this study was the inclusion of a comparison group of women of similar age with no history of cancer. The results indicated that the fatigue experienced by women after radiotherapy for breast cancer was not significantly different in intensity, duration, or disruptiveness from fatigue experienced by healthy women. In addition, radiotherapy recipients reported a quality of life similar to that of the healthy women. For both groups of women greater fatigue was related to a poorer quality of life. These findings suggest that following radiotherapy for breast cancer, women can expect to experience fatigue which is not worse than what they might normally experience. This information may be a useful part of psychoeducational interventions designed for women scheduled to begin radiotherapy for breast cancer.  相似文献

Based on organizational socialization literature (e.g., Bauer, Bodner, Erdogan, Truxillo, & Tucker, 2007; Kammeyer-Mueller & Wanberg, 2003; Saks, Uggerslev, & Fassina, 2007) and Conservation of Resources theory (COR theory; Hobfoll, 1989, 2001), this article aims to develop a conceptualization and a measurement of cognitive adjustment at work (CAW), as an indicator of psychological health in the workplace. Two studies, including three independent samples (NA = 296, NB = 350, NC = 139), were conducted to test an operational proposal of CAW. In Study 1, exploratory and confirmatory factor analyses, as well as reliability and temporal invariance analyses, were performed to test the structure of both the construct and the instrument. In Study 2, nomological network analysis was conducted. Results suggest strong empirical support for the structure and validity of CAW, defined as a second-order factor, which includes task adjustment, work group adjustment and organizational adjustment.  相似文献

State work engagement (SWE), a multidimensional construct of work-related well-being, was originally conceptualized as a trait, but diary studies have revealed substantial within-person fluctuations. Given that SWE is conceptualized as a work-related affective-motivational construct, the question arises as to whether SWE can be differentiated from other affective constructs. Thus, the goal of the present study was to compare SWE and state affect with respect to their degree of within-person variability and to examine their distinct relationships with health and performance variables (i.e., sleep quality and job performance). Fifty-two employees (44% female) participated in the study, which included 3 assessments per day over the course of 2 weeks. Our results revealed that energetic arousal and tense arousal fluctuated more strongly within days than vigor and absorption. Multilevel analyses demonstrated that high sleep quality predicted higher state affect but not higher SWE. In addition, vigor exhibited an inverted U-shaped relation with performance. In sum, SWE as a time-varying construct showed some overlap with state affect but also demonstrated discriminant validity.  相似文献

This paper explores the meaning of a patient's hallucinatory experiences in the course of a five times a week analysis. I will locate my understanding within the context of André Green's ideas on the role of the framing structure and the negative hallucination in the structuring of the mind. The understanding of the transference and countertransference was crucial in the creation of meaning and enabling the transformations that took place in the analytic process. Through a detailed analysis of a clinical example the author examines Bion's distinction between hysterical hallucinations and psychotic hallucinations and formulates her own hypothesis about the distinctions between the two. The paper suggests that whilst psychotic hallucinations express a conflict between life and death, in the hysterical hallucination it is between love and hate. The paper also contains some reflections on the dramatic nature of the analytic encounter.  相似文献

The present study examined the moderation effects of extraversion on the relationships between hiding and faking emotions, perceived satisfaction from intimate relationships, and reported physical health concerns. Four hundred and four Israeli participants, who were all involved in intimate relationships at the time of the study, responded to the Extraversion scale from the Big-Five Inventory, the DEELS to measure hiding and faking emotions, the SELF to assess physical health concerns, and the short version of the ENRICH to evaluate perceived satisfaction with intimate relationships. The mean age was 32.3 years (SD = 8.2); and the average length of time as a couple was 7.8 years (SD = 8.2). Of the participants, 198 were married (48.5%). The findings indicate that the effect of hiding negative emotions was stronger for perceived satisfaction with intimate relationships and physical health concerns than that for faking positive emotions. Extraverts who showed a higher frequency of hiding their negative emotions were significantly less satisfied with their relationships than introverts and they also tended to report more concerns with their physical health. These results were not found when extraverts reported a high frequency of faking positive emotions. These results are discussed in the context of the trait-behavior-concordance model and stress the importance of distinguishing faking from hiding.  相似文献

The effect of youth homelessness on age of entry into prostitution was tested, controlling for other known covariates using a multivariate model. Women (N = 96) who self-identified as having engaged in prostitution completed cross-sectional standardized questionnaires (Mage = 42.6, SD = 9.18; 62% African American). Women with a history of youth homelessness entered prostitution nearly 8 years earlier than their peers without this history (at 18 vs. 25 years old). Lack of a high school degree or equivalent also predicted an earlier age of entry (at 20 vs. 28 years old). Findings highlight the poverty dynamics that underlie the relationship between early entry into prostitution and homelessness. Young women, living on the street or in shelters, with limited education and employment opportunities, are at high risk of entering prostitution when they are barely out of adolescence. Future research will be better able to design age-specific prevention strategies.  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

Theory and research on status attainment in work groups primarily focuses on members’ abilities and characteristics that make them appear competent as predictors of their status in the group. We complement the abilities perspective with a social identity perspective by arguing that another important determinant of a member’s status is based on the extent to which the member serves the group’s interests. Specifically, we assert that a member’s identification with the group affects performance on behalf of the group, which in turn affects other members’ assessment of the member’s status. We test this social identity perspective on status attainment by studying the influence of members’ group identification on their performance and status in the group, while controlling for the members’ abilities and status characteristics. In a three-wave longitudinal field study following 33 work groups during a six-month group project, we find that members’ identification enhances their performance on behalf of the group, which in turn increases their status within the group. As such, our study advances insights in the determinants of status attainment in work groups and points to the relevance of the social identity approach for research on the antecedents of status in work groups.  相似文献

IntroductionThis article reports on a study of non-traffic related work safety among drivers of heavy goods vehicles in Denmark. In the heavy goods vehicle transport (HGV) sector only 6.4% of workplace accidents involving drivers are traffic related. HGV work is characterised by solitary work, as drivers tend to work at a physical distance from their own company and their working environment is also influenced by the working environment of other companies e.g. the places where they deliver goods. This study focuses on an analysis of HGV drivers’ and managers’ differentiated understandings of risk and safety and its management within an organisational context. The situational focus involves viewing HGV drivers’ working environment as a part of the organisational structure as well as of other social relationships. An understanding of safety culture as practice is applied with the view of identifying values and attitudes as well as organisational and technical aspects in relation to how individualist or collectivist understandings of risk and safety influence the working environment in HGVs.MethodThe study applied a mixed methods approach and in this article the qualitative interviews conducted with drivers and managers is the primary data source.ResultsThis study suggests a widespread understanding of drivers as being individually oriented in their work, from drivers and management alike. However, the study also demonstrates that, in conducting their work, the drivers are actually interdependent, and share knowledge frequently, albeit informally. The organisational structure of the company shapes their individual attitudes towards safety but they also report being dependent on relationships with, and information from, their fellow colleagues, former colleagues and friends who shape their understandings and attitudes towards hazards and safety practices. The analysis points to risk-taking and unsafe practices as prevalent among HGV drivers, who often refer to risk as trivial and the management of such risks as one’s own responsibility. Knowledge of how to manage risks in everyday practice is shown to be principally related to personal experiences but also to the good advice and examples of fellow drivers.ConclusionsThe analysis points to interdependent and collectivist practices among HGV drivers even though they are perceived as being individualistically oriented when it comes to safety. Therefore, non-traffic related safety practices, in this case the loading and unloading of vehicles, occur in the grey zone of organisational safety management. Despite the fact that organisational safety initiatives are initiated, the management sees limited possibilities for enforcing them and hence safety practice is often left to the individual driver.Practical applicationsA safety culture perspective might enhance work safety among HGV drivers if we are able to understand workplace culture in a pluralistic way. Collectivist practice among the drivers can be utilised in order to improve knowledge sharing and situational safety practices. The informal communication identified among the drivers might offer a new model for safety initiatives based on more collectivist, albeit informal, safety culture practices on behalf of HGV companies.  相似文献

Existing fatigued driving analysis methods mainly focus on lateral driving performance by using the measurements related to the steering wheel or lane position. There is a lack of research on longitudinal car following behavior. In this study, 40 professional drivers are invited to participate in field expressway driving experiment, lasting at least for 6 h. During the test, their performance is measured in terms of their self-reported fatigued driving level according to the Karolinska Sleepiness Scale (KSS), the PERcentage of eye CLOSures (PERCLOS) and the Time Headway (THW). Then the effects of the fatigued driving level on car following behavior are evaluated. The results indicate that the fatigue level (for both KSS and PERCLOS) has significantly impact on THW parameters, including the mean, standard deviation and minimum THW. An increase in KSS and PERCLOS leads to a lower mean and minimum THW. Meanwhile, the standard deviation of THW increases with the increase of KSS and PERCLOS. In conclusion, this study found that a higher fatigue level leads to the driver keeping a smaller THW when following another vehicle and choosing shorter THW to make lane change. More deviation of car following performance was also found with the increase of fatigue level. Therefore, the findings of this study can be used to explain fatigue as one of the major reasons for rear-end collisions. Also, the research findings demonstrate the impact of fatigue on driving behavior in terms of car following performance, which can be used as a measurement for monitoring fatigued drivers.  相似文献
