The construct of employability has been conceptually related to self-efficacy in different ways. Employability has sometimes been regarded as an equivalent to self-efficacy, or as a distinct but related phenomenon. Since the relationship between the two phenomena has not been subjected to empirical scrutiny, the aim of the present study is to analyze whether self-efficacy and employability are two distinct but related constructs, and if they are, to investigate the direction of their relationship. The data (N = 1730) were collected through a two-wave longitudinal survey with one year between each data collection (2005 and 2006). The results of confirmatory factor analysis showed that the measures of employability and self-efficacy were distinct from one another, within and over measurement points, indicating that these are related but separate constructs. The results of latent variable cross-lagged analysis showed that employability predicted subsequent self-efficacy, even after controlling for age, gender, educational level, and regional differences. Thus, employability is not an expression of efficacy beliefs, but rather, the strengthening of employability perceptions may have beneficial effects on more general efficacy beliefs.  相似文献

The hypothesis that the degree to which disease disrupts daily functioning is inversely associated with happiness is widely accepted, yet existing literature offers little direct evidence in its support. This paper explores the hypothesized association in a community-based sample of 383 older adults. To assess the degree to which disease disrupts daily functioning we developed a measure—called the freedom-from-debility score—based on four Short Form-12 (SF-12) Health Survey questions explicitly designed to represent “limitations in physical activities because of health problems” and “limitations in usual role activities because of physical health problems.” The results were consistent with the hypothesis. When participants were divided into categories based on their freedom-from-debility score, median happiness scores were monotonically increasing across categories. Controlling for demographic and socio-economic factors as well as health status (measured both subjectively and objectively), a one-point increase in freedom-from-debility score (on a scale from 0 to 100) was associated with a three-percent reduction in the odds of lower-quartile happiness. The results support the contention that health status is one of the most influential predictors of happiness, that the association between health status and happiness depends greatly on the manner in which health status is measured, and that the degree to which disease disrupts daily functioning is inversely associated with happiness.  相似文献

Selection experiments and game theory models have revealed that the changes in agonistic behavior following selection for rapid growth rate of fish depend on the access of food. If food is spatially restricted and in excess of demand, the intensity of agonistic behaviors will decrease. This prediction was tested in an experiment on wild and sea‐ranched brown trout (Salmo trutta L.) fry originating from a common stock. Agonistic behavior, activity, and specific growth rate were studied in tanks (56 × 56 cm) at high (159.4 fry/m2) and low (9.6 fry/m2) stocking densities given either a large or small food ration (3.0% and 1.5%, respectively, food per total body weight and day). Observations were done during 4 days in each trial. Generally, fry of sea‐ranched origin had a higher growth rate. No differences in activity were found. Intensity of agonistic behavior was higher among wild groups. There was a tendency for interaction between density and strain, e.g., wild fish were relatively more aggressive at higher densities. Food ration had no effect on level of agonistic behavior. These results indicate that the selection for rapid growth in hatcheries may indirectly select for reduced aggressiveness. Genetic integrity and diversity of wild populations may be threatened when interbreeding occurs between wild and hatchery fish. Aggr. Behav. 28:145–153, 2002. © 2002 Wiley‐Liss, Inc.  相似文献

The study investigates the effects of home-based telework on quality of life (QoL). Four dimensions of QoL were analysed; overall satisfaction with life, sense of belonging, sense of becoming and sense of being. Through cross-national survey data (from 217 job holders and 112 partners) and by means of structural equation modeling, a positive association was found between home-based telework to a worker's sense of belonging (beta = 0.30, p < 0.001). On the other hand, a negative path was detected from the job holder's home-based telework to his or her partner's overall satisfaction with life (beta = –0.27, p < 0.05). After controlling for subdimensions of life quality, home-based work did not affect the job holder's overall life satisfaction. Moreover, the more concentration the job holder reported, the lower the sense of belonging was reported by his or her partner (beta = –0.28, p < 0.05). No simple explanation for the negative effects were found, but our interviews with the group of workers and their families leave us the impression that the problem of overworking and withdrawal was most relevant to the cases, in combination with negative spill-over effects and unclear boundary settings in the home.  相似文献

We use the metatheoretical principle of cumulative advantage as a framework to understand the presence of heavy‐tailed productivity distributions and productivity stars. We relied on 229 datasets including 633,876 productivity observations collected from approximately 625,000 individuals in occupations including research, entertainment, politics, sports, sales, and manufacturing, among others. We implemented a novel methodological approach developed in the field of physics to assess the precise shape of the productivity distribution rather than relying on a normal versus nonnormal artificial dichotomy. Results indicate that higher levels of multiplicity of productivity, monopolistic productivity, job autonomy, and job complexity (i.e., conductors of cumulative advantage) are associated with a higher probability of an underlying power law distribution, whereas lower productivity ceilings (i.e., insulator of cumulative advantage) are associated with a lower probability. In addition, higher levels of multiplicity of productivity, monopolistic productivity, and job autonomy were associated with a greater proportion of productivity stars (i.e., productivity distributions with heavier tails), whereas lower productivity ceilings were associated with a smaller proportion of productivity stars (i.e., productivity distributions with lighter tails). Results serve as a building block for future theory development and testing efforts aimed at understanding why, when, and how the distribution of individual productivity may follow a nonnormal curve—and to what extent. We also discuss implications for organizations and management in terms of the design and implementation of human resource systems (e.g., selection, training, compensation), as well as for individuals interested in becoming productivity stars themselves.  相似文献

The primary objective of this study was to examine the psychometric properties of a measure of anger/rage attacks—the Rage Outburst and Anger Rating Scale (ROARS)—in a sample of youth (n = 81, ages 7–17 years, 72.8 % male) receiving treatment at an outpatient pediatric psychiatric clinic. A trained rater completed the ROARS and Clinical Global Impression-Rage (CGI-Rage). Children completed the Spence Children’s Anxiety Scale for Children and Center for Epidemiological Studies Depression Scale. Parents completed the Spence Children’s Anxiety Scale for Parents. Internal consistency (α = .89), inter-rater reliability (κ = .94) and 1-week test–retest reliability (r = .72) were calculated for the ROARS. The ROARS was correlated with CGI-Rage (r = .68, ρ < .001), although not with parent- and child-rated anxiety symptoms or with child-rated depressive symptoms. Implications regarding clinical utility of the ROARS and directions for future research are discussed.  相似文献

Korsakoff's syndrome (KS) is characterized by explicit amnesia, but relatively spared implicit memory. The aim of this study was to assess to what extent KS patients can acquire spatial information while performing a spatial navigation task. Furthermore, we examined whether residual spatial acquisition in KS was based on automatic or effortful coding processes. Therefore, 20 KS patients and 20 matched healthy controls performed six tasks on spatial navigation after they navigated through a residential area. Ten participants per group were instructed to pay close attention (intentional condition), while 10 received mock instructions (incidental condition). KS patients showed hampered performance on a majority of tasks, yet their performance was superior to chance level on a route time and distance estimation tasks, a map drawing task and a route walking task. Performance was relatively spared on the route distance estimation task, but there were large variations between participants. Acquisition in KS was automatic rather than effortful, since no significant differences were obtained between the intentional and incidental condition on any task, whereas for the healthy controls, the intention to learn was beneficial for the map drawing task and the route walking task. The results of this study suggest that KS patients are still able to acquire spatial information during navigation on multiple domains despite the presence of the explicit amnesia. Residual acquisition is most likely based on automatic coding processes.  相似文献
