Previous research showed that daily manifestations of career adaptability fluctuate within individuals over short periods of time, and predict important daily job and career outcomes. Using a quantitative daily diary study design (N = 156 employees; 591 daily entries), the author investigated daily job characteristics (i.e., daily job demands, daily job autonomy, and daily supervisory career mentoring) and daily individual characteristics (i.e., daily Big Five personality characteristics, daily core self-evaluations, and daily temporal focus) as within-person predictors of daily career adaptability and its four dimensions (concern, control, curiosity, and confidence). Results showed that daily job demands, daily job autonomy, daily conscientiousness, daily openness to experience, as well as daily past and future temporal focus positively predicted daily career adaptability. Differential results emerged for the four career adaptability dimensions. Implications for future research on within-person variability in career adaptability are discussed.

A model comprising several servers, each equipped with its own queue and with possibly different service speeds, is considered. Each server receives a dedicated arrival stream of jobs; there is also a stream of generic jobs that arrive to a job scheduler and can be individually allocated to any of the servers. It is shown that if the arrival streams are all Poisson and all jobs have the same exponentially distributed service requirements, the probabilistic splitting of the generic stream that minimizes the average job response time is such that it balances the server idle times in a weighted least-squares sense, where the weighting coefficients are related to the service speeds of the servers. The corresponding result holds for nonexponentially distributed service times if the service speeds are all equal. This result is used to develop adaptive quasi-static algorithms for allocating jobs in the generic arrival stream when the load parameters are unknown. The algorithms utilize server idle-time measurements which are sent periodically to the central job scheduler. A model is developed for these measurements, and the result mentioned is used to cast the problem into one of finding a projection of the root of an affine function, when only noisy values of the function can be observed

Ill-health prevails in the workplace. A key problem encountered in the area of stress management is a lack of research into the way job burnout turns into mental problems, especially depressive symptoms, the most prevalent and costly psychiatric condition in the workplace. This research belongs to a cross-discipline area of industrial psychiatry and organizational behavior, which has seldom been investigated before. This research will contribute to the theoretical development of organizational behavior, especially to stress management and industrial psychiatry. This study aims to explore etiological factors and mechanisms of depressive symptoms of workers in the financial industry. By using literature review, semi-structured interviews and surveys as the major research methods, this Ph.D. study systematically investigated the risk factors of workers’ depressive symptoms within and outside of the work area. These risk factors are worker-work environment fits, work family conflicts, and workers’ psychological vulnerabilities to depression. A thorough literature review and 20 semi-structured interviews of brokers in different kinds of financial markets show the feasibility and necessity of this Ph.D. study when it comes to the issue of financial workers’ depressive symptoms. Two surveys of workplace-etiological factors of depressive symptoms were conducted among 244 financial workers and 1024 financial workers. This cross-sample verification showed that worker-work environment fit was a good framework to study risk factors of workers’ depressive symptoms. Results revealed that job demands-abilities misfit could lead to job burnout which in turn contributed to worker’s depressive symptoms; besides this, work effort-reward imbalance could directly cause workers’ depressive symptoms. Emotional labor enhanced the positive effect of job burnout on workers’ depressive symptoms. In the third study, a prominent risk factor outside of the work area, namely work family conflict, and workers’ psychological vulnerabilities of depression were included with workplace etiological factors to investigate the overall predictive model of depressive symptoms of financial workers. The survey was conducted among the same 1024 financial workers. Results indicated that work effort-reward imbalance, job burnout and work interfering in family life were three external etiological factors of workers’ depressive symptoms. Neuroticism, autonomy and low emotional intelligence were three individual etiological factors which had a positive effect on workers’ depressive symptoms. Moreover, neuroticism enhanced the relationship between job burnout and depressive symptoms as well as between work interfering in family life and depressive symptoms. Autonomy aggravated the relationship between job burnout and depressive symptoms. However, emotional intelligence attenuated the relationship between job burnout and depressive symptoms as well as between work effort-reward imbalance and depressive symptoms. Besides, workers’ dysfunctional attitudes played a partial mediating role in the relationships between above etiological factors and depressive symptoms. In the same sample, research evidence of impairments of workers’ depressive symptoms to their work-life quality was also obtained. Specifically, depressive symptoms could predict workers’ presenteeism, absenteeism and turnover intention. Their subjective well-being was also lowered when suffering more severe depressive symptoms. This research provides a theoretical basis to management practices targeted to set up the Employee Assistance Program or even more specilised rehabilitation programs for workers with depressive symptoms so as to improve their work-life quality and and establish a harmonious enterprise.

Work engagement (WE) has recently become a fashionable term among Human Resource practitioners and Organizational Behavior researchers. However, academic research that has theoretically examined WE at the psychological level is limited, as is research on its place among other job attitude constructs that are used to describe employees at work, and its antecedents and consequences. This dissertation addresses a number of issues with regard to the discriminant validity of WE, the influences of WE and the mediating role of affective commitment, and the interaction effects of different job demands, job resources and personal resources on WE. The major findings are listed as follows: Firstly, the concept of WE is different from JB and job involvement (JI), and is more positively related to quality of employees’ work and life than the other two concepts. Specifically, WE is more related to employees’ creative performance than JB does; compared with JI, WE can better predict task performance, creative performance, organizational citizenship behavior (OCB), and life satisfaction; although both WE and JB cause work to family conflict, WE improves employees’ life satisfaction, while JB is deleterious to life satisfaction. Secondly, WE influences employees’ work and life directly or through the mediation effect of affective commitment. Specifically, WE reduces employees’ turnover intention and increase their OCBs by the the mediation effect of effective commitment. Furthermore, WE is positively related to task performance, creative performance, and life satisfaction directly. Thirdly, challenge job demands influence WE by the mediation effect of intrinsic motivation, and the impact of challenge job demands on WE is moderated by perceived supervisor support and growth needs. Specifically speaking, challenge job demands enhance employees’ intrinsic motivation, therefore boost WE. Employees with higher growth needs are more likely to be motivated by challenge job demands. In other words, the moderation effect of growth need is mediated by intrinsic motivation. In addition, those who perceive more supervisor support have higher level of WE when challenge job demands are high.

Aims: To examine whether job strain (ie, excessive demands combined with low control) is related to smoking cessation.

Methods: Prospective cohort study of 4928 Finnish employees who were baseline smokers. In addition to individual scores, coworker-assessed work unit level scores were calculated. A multilevel logistic regression analysis, with work units at the second level, was performed.

Results: At follow-up, 21% of baseline smokers had quit smoking. After adjustment for sex, age, employer and marital status, elevated odds ratios (ORs) for smoking cessation were found for the lowest vs the highest quartile of work unit level job strain (OR 1.43, 95% CI 1.17 to 1.75) and for the highest vs the lowest quartile of work unit level job control (OR 1.61, 95% CI 1.31 to 1.96). After additional adjustment for health behaviours and trait anxiety, similar results were observed. Further adjustment for socioeconomic position slightly attenuated these associations, but an additional adjustment for individual strain/control had little effect on the results. The association between job strain and smoking cessation was slightly stronger in light than in moderate/heavy smokers. The results for individual job strain and job control were in the same direction as the work unit models, although these relationships became insignificant after adjustment for socioeconomic position. Job demands were not associated with smoking cessation.

Conclusions: Smoking cessation may be less likely in workplaces with high strain and low control. Policies and programs addressing employee job strain and control might also contribute to the effectiveness of smoking cessation interventions.

Objective: The proportion of overweight and obese people has grown rapidly, and obesity has now been widely recognized as an important public health problem. At the came time, stress has increased in working life. The 2 problems could be connected if work stress promotes unhealthy eating habits and sedentary behavior and thereby contributes to weight gain. This study explored the association between work stress and body mass index (BMI; kg/m(2)). Methods: We used cross-sectional questionnaire data obtained from 45,810 female and male employees participating in the ongoing Finnish Public Sector Cohort Study. We constructed individual-level scores, as well as occupational- and organizational-level aggregated scores for work stress, as indicated by the demand/control model and the effort-reward imbalance model. Linear regression analyses were stratified by sex and socioeconomic status (SES) and adjusted for age, marital status, job contract, smoking, alcohol consumption, physical activity, and negative affectivity. Results: The results with the aggregated scores showed that lower job control, higher job strain, and higher effort-reward imbalance were associated with a higher BMI. In men, lower job demands were also associated with a higher BMI. These associations were not accounted for by SES, although an additional adjustment for SES attenuated the associations. The results obtained with the individual-level scores were in the same direction, but the relationships were weaker than those obtained with the aggregated scores. Conclusions: This study shows a weak association between work stress and BMI.

Background: Organizational features can affect how staff view their quality of work life. Determining staff perceptions about quality of work life is an important consideration for employers interested in improving employee job satisfaction. The purpose of this study was to identify organization specific predictors of job satisfaction within a health care system that consisted of six independent health care organizations.

Methods: 5,486 full, part and causal time (non-physician) staff on active payroll within six organizations (2 community hospitals, 1 community hospital/long-term care facility, 1 long-term care facility, 1 tertiary care/community health centre, and 1 visiting nursing agency) located in five communities in Central West Ontario, Canada were asked to complete a 65-item quality of work life survey. The self-administered questionnaires collected staff perceptions of: co-worker and supervisor support; teamwork and communication; job demands and decision authority; organization characteristics; patient/resident care; compensation and benefits; staff training and development; and impressions of the organization. Socio-demographic data were also collected.

Results: Depending on the organization, between 15 and 30 (of the 40 potential predictor) variables were found to be statistically associated with job satisfaction (univariate analyses). Logistic regression analyses identified the best predictors of job satisfaction and these are presented for each of the six organizations and for all organizations combined.

Conclusions: The findings indicate that job satisfaction is a multidimensional construct and although there appear to be some commonalities across organizations, some predictors of job satisfaction appear to be organization and context specific.

Unfavorable work characteristics, such as low job control and too high or too low job demands, have been suggested to increase the likelihood of physical inactivity during leisure time, but this has not been verified in large-scale studies. The authors combined individual-level data from 14 European cohort studies (baseline years from 19851988 to 20062008) to examine the association between unfavorable work characteristics and leisure-time physical inactivity in a total of 170,162 employees (50 women; mean age, 43.5 years). Of these employees, 56,735 were reexamined after 29 years. In cross-sectional analyses, the odds for physical inactivity were 26 higher (odds ratio 1.26, 95 confidence interval: 1.15, 1.38) for employees with high-strain jobs (low control/high demands) and 21 higher (odds ratio 1.21, 95 confidence interval: 1.11, 1.31) for those with passive jobs (low control/low demands) compared with employees in low-strain jobs (high control/low demands). In prospective analyses restricted to physically active participants, the odds of becoming physically inactive during follow-up were 21 and 20 higher for those with high-strain (odds ratio 1.21, 95 confidence interval: 1.11, 1.32) and passive (odds ratio 1.20, 95 confidence interval: 1.11, 1.30) jobs at baseline. These data suggest that unfavorable work characteristics may have a spillover effect on leisure-time physical activity.

Ce mémoire vise à vérifier l’effet modérateur de la relation d’encadrement LMX sur la relation entre les demandes du travail et l’épuisement émotionnel. Nous avons d’abord étudié la relation d’encadrement LMX et ses effets multiples, particulièrement sur le stress. Nous avons envisagé le LMX comme une ressource qui peut atténuer les effets des demandes du travail (conflit, surcharge et l’ambiguïté de rôle) sur l’épuisement émotionnel, et ce, avec comme fondement théorique le modèle des tensions du travail de Karasek (1979). Pour vérifier notre modèle, nous avons procédé à une analyse secondaire de données recueillies dans le cadre provenant d’une étude précédente réalisée à l’Institut de gériatrie de l’Université de Sherbrooke en 1996. Des analyses descriptives nous ont permis de valider deux de nos trois principales hypothèses à l’effet que le LMX agit comme modérateur sur la relation entre les demandes du travail et l’épuisement émotionnel. En effet, les résultats montrent que plus le LMX est de qualité, moins les relations entre le conflit de rôle et l’épuisement émotionnel ainsi qu’entre la surcharge de rôle et l’épuisement émotionnel sont significatives. Toutefois, nos résultats indiquent que plus le LMX est de qualité, plus l’effet de l’ambiguïté de rôle est relié à l’épuisement émotionnel.

Debido a las crisis mundiales, la perdurabilidad empresarial se ha convertido en la primera preocupación de las organizaciones, puesto que los problemas económicos en otros países pueden generar un efecto negativo en las condiciones del mercado doméstico, que junto con el entorno empresarial complejo y dinámico en el que se deben desempeñar las empresas hoy en día gracias a la globalización, sumado al aumento en la competitividad nacional e internacional, la perdurabilidad de las empresas se está viendo seriamente comprometida. Lo anterior, ha llevado a las empresas a buscar nuevas formas de mejorar su salud financiera. Para medir la salud financiera empresarial, se pueden usar distintos indicadores como lo es el flujo de caja que está asociado con la rentabilidad, el patrimonio que está asociado a las dificultades financieras, entre otros, o a través de varios modelos de bancarrota, los cuales, por medio de un conjunto de ratios financieros, reflejan el estado actual de la organización y su probabilidad de fracaso en el futuro. Las estrategias comunitarias y el marketing permiten incrementar la salud financiera de las empresas a través de la orientación al cliente y el establecimiento de relaciones gana-gana a largo plazo con las diferentes comunidades con las que se relaciona la organización.

Antecedentes: Los factores de Riesgo psicosocial según la resolución 2646 de 2008 “comprenden los aspectos intralaborales, extralaborales o externos a la organización y las condiciones individuales o características intrínsecas al trabajador, los cuales en una interrelación dinámica, mediante percepciones y experiencias, influirían en la salud y el desempeño de las personas”. El objetivo del estudio es establecer la prevalencia de factores de riesgo psicosocial y la asociación existente en la población trabajadora del área administrativa y asistencial, en una empresa del sector salud nivel II, Yopal, 2014 Materiales y método: Se diseñó un estudio de corte transversal para establecer la prevalencia de los factores de riesgo psicosocial en una población de 92 trabajadores del área administrativa (50) y asistencial (42) en una empresa del sector salud nivel II en Yopal, por medio de la batería de Riesgo Psicosocial del Ministerio de la Protección Social. Resultados: Se realizó un análisis multivariado, se puede afirmar con un nivel de confianza del 95% que en la población de estudio, la prevalencia de riesgo intralaboral en la población administrativa está entre el 9,5% y 34,5% y en los trabajadores del área asistencial entre el 9,7% y el 37,9%. El riesgo extralaboral en el área administrativa está entre el 4,8% y el 27,2%, en el área asistencial la prevalencia está entre el 1,5% y el 19,5%. La prevalencia de Riesgo de Estrés se encuentra en la población administrativa entre el 29,2% y el 58,8% y en el área asistencial entre el 17,9% y el 48,8%. Se encontró una asociación (p = 0,007) entre estado civil y riesgo intralaboral en la población asistencial, entre tipo de vivienda y nivel de estres (p= 0,003) en la población administrativa, y entre número de personas a cargo económicamente y riesgo extralaboral (p=0,004) en el área asistencial. Discusión: La prevalencia de riesgo psicosocial es evidente en las dos áreas de trabajo tanto administrativos como asistenciales, sin embargo se encuentra una prevalencia mayor de riesgo en el área asistencial en la dimensión exigencias del rol dado a un incremento en la responsabilidad y tiempo extra que se debe realizar para el desarrollo de tareas y su cumplimiento ante el rol desempeñado; los resultados permiten implementar programas de vigilancia epidemiológica que permitan mitigar y controlar los hallazgos en este estudio.

L'objectiu d'aquesta tesi doctoral consisteix en determinar si el model de gestió dels recursos humans de les empreses matrius japoneses es transferible a les filials japoneses de Catalunya. Per tot això després d'un estudi teòric sobre la literatura existent del model de gestió dels recursos humans japonès i la internacionalització dels recursos humans, s'ha realitzat un treball empíric mitjançant una enquesta a les filials japoneses instal.lades a Catalunya. En el qüestionari s'analitzen diferents àmbits de la gestió dels recursos humans i que constitueixen les 7 hipòtesis del nostre treball de camp basades en el model de recursos humans japonès referides a: 1- Reclutament i selecció, 2- Promoció i Rotació, 3- Lideratge, comunicació i treball en equip, 4- Motivació, clima laboral i cultura empresrial, 5- Formació i desenvolupament, 6- Avaluació de l'acompliment, y 7- Retribució i beneficis socials. Tot això ens ha indicat quina es la tendència del model japonès de recursos humans a les filials catalanes tenint en compte que estem analitzant un contexte cultural diferent a la idiosincrasia dels treballadors japonesos. El treball ens ha permés de proposar dues línies d'investigació, una a determinar en el temps i una altre en l'espai. En el temps amb la nova generació s'està produint un canvi cultural en el qual els joves japonesos intenten importar part dels valors occidentals que es veurà reflectit al llarg de 10-20 anys. I en l'espai l'aplicació de l'estudi a altres països europeus, com Anglaterra, França i Alemanya que són els principals països on els japonesos prefereixen instal.lar-se.
