The Fourth Industrial Revolution: Issues and Implications for Career Research and Practice 下载免费PDF全文
Andreas Hirschi 《The Career development quarterly》2018,66(3):192-204
The accelerating digitization and automation of work, known as the 4th industrial revolution, will have an enormous impact on individuals’ career experiences. Yet, the academic literature in vocational psychology and career research has been remarkably silent on this trend so far. This article summarizes some of the most important issues of the 4th industrial revolution as they pertain to career development. The author then critically reviews how current models and frameworks of career development are suitable for addressing these emerging issues. Opportunities for future career development research and practice are outlined. 相似文献

The use of parametric linear mixed models and generalized linear mixed models to analyze longitudinal data collected during randomized control trials (RCT) is conventional. The application of these methods, however, is restricted due to various assumptions required by these models. When the number of observations per subject is sufficiently large, and individual trajectories are noisy, functional data analysis (FDA) methods serve as an alternative to parametric longitudinal data analysis techniques. However, the use of FDA in RCTs is rare. In this paper, the effectiveness of FDA and linear mixed models (LMMs) was compared by analyzing data from rural persons living with HIV and comorbid depression enrolled in a depression treatment randomized clinical trial. Interactive voice response systems were used for weekly administrations of the 10-item Self-Administered Depression Scale (SADS) over 41 weeks. Functional principal component analysis and functional regression analysis methods detected a statistically significant difference in SADS between telphone-administered interpersonal psychotherapy (tele-IPT) and controls but linear mixed effects model results did not. Additional simulation studies were conducted to compare FDA and LMMs under a different nonlinear trajectory assumption. In this clinical trial with sufficient per subject measured outcomes and individual trajectories that are noisy and nonlinear, we found FDA methods to be a better alternative to LMMs. 相似文献

Work-related mental distress and its impact on employees’ working life is a mounting issue among Finnish social workers. This article focuses on identifying the factors associated with child welfare social workers’ occupational well-being. The occupational well-being of Finnish child welfare social workers (N?=?364) and social workers whose duties do not include child protection work (N?=?524) was explored and compared with each other using t-test statistics and logistic regression analysis. The data, collected in 2014/2015, were obtained from an ongoing longitudinal cohort study on work-related well-being among Finnish public sector employees. A multi-dimensional and holistic approach to occupational well-being was used as the outline for the analysis and comparison of the two groups. Child protection social workers reported higher levels of burnout and secondary traumatic stress than social workers without child protection duties. Despite these burdens, both groups showed a similar level of general health, compassion satisfaction and overall occupational well-being. Individual and organizational factors associated with high occupational well-being were identified. Supervision was found to be an important supporting element. This study identified multiple determinants related to social workers’ occupational well-being, comprising positive and negative elements with regard to organizational and individual factors. 相似文献

Jolly-Seber models A, B, D and 2 were used to investigate capture-recapture data. The standard Jolly-Seber model A (time-dependent survival phi and capture probability p ) fits capture-recapture data of migrating passerines. Captures from a long-term mist-netting study (Mettnau Peninsula, SW Germany) at a stop-over site were used to estimate stop-over length from survival rate between days and capture probability. For some data, model 2 could be used, indicating a termporary reduction in 'survival' rate. Application of models B and D gave poor results. The total number of birds stopping over, i.e. population size, was estimated from captures of 1-5 line transects of nets in the spatial trapping design. Behaviour, movements within the stop-over site, catchability and ecophysiological covariables such as moult, fat deposition and climatic parameters are likely to have strong influence on the estimation of capture parameters. 相似文献

Pay-as-you-go (PAYG) pension schemes can contribute to better intergenerational risk-sharing and diversification. However,
different variants of PAYG schemes entail different properties in these respects. In a stochastic 2-OLG model we compare PAYG
schemes with fixed contribution rates and such with fixed replacement rates. The literature has shown that the former are
preferable to the later from an ex ante perspective. We derive the opposite result for the ex post perspective. Here, schemes with fixed replacement rates are unambiguously preferable: they enhance intergenerational risk-sharing,
lead to a higher savings and higher utility levels. We further show that, from an ex ante (veil-of-ignorance), perspective both schemes are non-comparable if the effect that fixed-replacement schemes serve as an
insurance device for old-age income is properly accounted for.

This paper is an attempt to analyze the senses from a sociological perspective and within the context of Niklas Luhmann’s reflexive theory of social systems. A functional specification of the persceptive senses for the constitution and structuring of social systems will be achieved by means of the basic distinctions of system/environment, consciousness/communication, and interaction/society. Essentially, four levels can be distinguished with regard to perception, consciousness, and communication: 1) reflexive sensory perception of perceptions, 2) sensory perception of communication, 3) sensory perception due to communication, 4) communication based on purposefully initiated perception. As a result, the senses can be understood, on the one hand, as an infrastructural resource of communication and an ecological condition of society; on the other hand, they are themselves a binding, immanent structural principle of the social, or, more precisely, of interactions. 相似文献

ABSTRACTThis study set out to explore the effects of accumulating work experience on the association between job decision latitude and its interaction with job demands and work engagement. Our ten-year longitudinal study followed 333 junior physicians in postgraduate training at baseline. We used self-report measures in four assessment waves, and we conducted path analyses to investigate linear and curvilinear regression effects. Results show that high job decision latitude was associated with high work engagement at all levels of work experience, with strongest associations at baseline and after ten years. Only for novices did job decision latitude buffer the negative association between job demands and work engagement. At the stage of high work experience, low levels of job decision latitude were weakly associated with work engagement, whereas with higher levels of job decision latitude, the positive association seemed to strengthen. Our findings indicate that job decision latitude is a key job resource at all stages of work experience, with stronger effects among novices and experts. Organisations’ work design efforts should include job decision latitude to promote work engagement across employees’ different career stages, with consideration to job entrants and experts in order to tailor specific work design solutions. 相似文献

We consider the problem of scheduling n jobs withrelease dates on m identical parallel machines to minimize the average completion time of the jobs. We prove that the ratio of the average completion time of the optimal nonpreemptive schedule to that of the optimal preemptive schedule is at most 7/3, improving a bound of
