The authors explored predictions of general job satisfaction at early and middle adulthood and uncovered several findings about developmental processes associated with job satisfaction. Tests of life‐span career theory propositions revealed that neither choice‐job congruence nor gender added significantly to predictions of job satisfaction at 2 career stages. Earlier occupational choice and current job added to predictions of midcareer (modal age 43 years) job satisfaction, especially for men. The predictability of job satisfaction is apparently influenced by the career stage when satisfaction is appraised. 相似文献

Chinese version of the OSI: A validation study 总被引:5,自引:0,他引:5

This article examines the construct validity of the Occupational Stress Indicator (OSI) in its Chinese version as well as its criterion-oriented validity against self-reported data on absenteeism and accidents, using a final sample of 1054 workers in the Chinese manufacturing and power industries. The divergent and convergent validities of five of the OSI scales—Job satisfaction, Physical ill-health, Mental ill-health, Type A behaviour and Control—were examined by a multimethod-multitrait matrix technique. Results indicated that the Chinese OSI had fairly good validity in relation to other well-established measures as well as relevant organizational behaviours. 相似文献

Juvenile crime affects not only the victims of the crime but also the delinquents’ future. How to prevent adolescent criminal behavior has become an important public policy issue. This study contributes to this interesting issue by examining the relationship between tattooing and adolescents’ criminal behavior. In particular, this study investigates whether or not having a tattoo/tattoos is connected to the incidence of various criminal activities, including: larceny, robbery, fraud, assault, drug use, and homicide. A unique sample of 973 juvenile detainees drawn from the administrative profiles in Taiwan and the coarsened exact matching method were utilized. Results show that compared to their nontattooed counterparts, tattooed juvenile detainees were significantly more likely to commit fraud, assault, drug abuse, and homicide by 3%, 13%, 9%, and 9%, respectively. In contrast, tattooing was not significantly associated with larceny or robbery. From a policy perspective, given the significant link between tattooing and criminal behavior, the presence of a tattoo in adolescents may serve as a valuable indicator regarding adolescents’ high probability of committing crimes. 相似文献

ABSTRACT This study explored and conceptualised service users’ experiences in online outreach projects supported by the Hong Kong SAR government. Fifteen active users were interviewed. The study used thematic analysis to explore service users’ experiences that might not have been possible without technology. Participant utterances were non-mutually-exclusively tagged with a specific theme. Each utterance reflected an aspect of user experience which combined a technical component with a service-need component. Six themes were identified, including: (i) Personalised newsfeeds help identify service information and news, (ii) Online status indicators improve service accessibility, (iii) Online communications enable a disinhibition effect, (iv) Asynchronous communications facilitate continual feedback loops, (v) Incomplete communicative modalities may cause misunderstanding and (vi) Asynchronous communication may disrupt conversations. The findings reveal that there are middle-level concepts between broad social work concepts and ever-changing technology. Implications for research and practice are discussed. 相似文献

Mixed-Weibull distribution has been used to model a wide range of failure data sets, and in many practical situations the number of components in a mixture model is unknown. Thus, the parameter estimation of a mixed-Weibull distribution is considered and the important issue of how to determine the number of components is discussed. Two approaches are proposed to solve this problem. One is the method of moments and the other is a regularization type of fuzzy clustering algorithm. Finally, numerical examples and two real data sets are given to illustrate the features of the proposed approaches. 相似文献

Artificial neural networks are new methods for classification. We investigate two important issues in building neural network models; network architecture and size of training samples. Experiments were designed and carried out on two-group classification problems to find answers to these model building questions. The first experiment deals with selection of architecture and sample size for different classification problems. Results show that choice of architecture and choice of sample size depend on the objective: to maximize the classification rate of training samples, or to maximize the generalizability of neural networks. The second experiment compares neural network models with classical models such as linear discriminant analysis and quadratic discriminant analysis, and nonparametric methods such as k-nearest-neighbor and linear programming. Results show that neural networks are comparable to, if not better than, these other methods in terms of classification rates in the training samples but not in the test samples. 相似文献

This article examines middle class children's and parents' complex engagements with contemporary practices of cultivation, care and surveillance focused on children's social and emotional capacities and differences. Emblematic of a sociality and emotion-focused biopolitics of childhood, such care provokes moments of spontaneous connection and self-expression for children even as they engage dynamics of disciplining control and normalisation, an outcome that may work against and towards the objectives of care. Moreover, parental investments in social–emotional care reveal adults' conflicted implication in dynamics of child normalisation, and the potential of this form of caretaking to generate politically valuable empathic insight. 相似文献

Bartlett correction constitutes one of the attractive features of empirical likelihood because it enables the construction of confidence regions for parameters with improved coverage probabilities. We study the Bartlett correction of spatial frequency domain empirical likelihood (SFDEL) based on general spectral estimating functions for regularly spaced spatial data. This general formulation can be applied to testing and estimation problems in spatial analysis, for example testing covariance isotropy, testing covariance separability as well as estimating the parameters of spatial covariance models. We show that the SFDEL is Bartlett correctable. In particular, the improvement in coverage accuracies of the Bartlett‐corrected confidence regions depends on the underlying spatial structures.

An Examination of the Dual Model of Perfectionism and Adolescent Athlete Burnout: A Short-Term Longitudinal Research 总被引:1,自引:0,他引:1
The dual model of perfectionism (Slade and Owens, Behav Modificat 22(3):372–390, 1998) is adopted to examine the influence
of adaptive and maladaptive perfectionism on adolescent athlete burnout in Taiwan. Participants were 188 high school adolescent
student-athletes (M = 16.48, SD = .59). They were administered the Multidimensional Inventory of Perfectionism in Sport (Stoeber et al., Pers Individ Dif
43(1):131–141, 2007) and the Chinese Athlete Burnout Questionnaire (ABQ) (Lu et al., Phys Educ J 39(3):83–94, 2006). A field
longitudinal design was used. In cross-sectional analyses, hierarchical multiple regressions indicated that adaptive perfectionism
negatively predicted athlete burnout while maladaptive perfectionism had an inverse relationship with burnout. However, after
controlling for the initial scores of burnout, neither adaptive nor maladaptive perfectionism significantly predicted athlete
burnout after a three month interval. Possible mechanisms of this relation, limitations, and practical implications are discussed. 相似文献
