Work values might be proximal predictors of individuals' late‐career intentions because they serve as guiding principles for the selection, evaluation, and justification of vocational behavior. The purpose of this study was to examine the relationship between work values and post‐retirement work intentions. The authors investigated individual work values within the structure of 4 higher order values elaborated on by Schwartz et al. ( 2012 ). Relationships between work values and 4 types of post‐retirement work intentions were examined. Data from 1,071 employees of a German logistics company were used to test the hypotheses. The results of a structural equation model indicated that work values were differentially related to the 4 types of post‐retirement work intentions. The identified work value–work type combinations add to the literature on post‐retirement work. Practice implications for promoting positive individual and organizational outcomes are drawn from the results.  相似文献

This study used a factorial experimental design and a new modeling methodology to investigate the impact of a number of labor scheduling flexibility alternatives and labor requirements characteristics on labor utilization within a tour scheduling environment. Break-placement flexibility and shift-length flexibility were found to be extremely effective in improving labor utilization for all labor requirement distributions used. Flexibility with respect to the number of days included in a tour schedule resulted in substantial improvement in labor utilization for all labor requirements distributions exhibiting daily and/or weekly variation. Surprisingly, virtually no improvement in labor utilization was achieved for any labor requirement distribution by the removal of requirements for consecutive days off. In addition, almost no improvement was found by allowing the shift start time to vary across the working days included in tours. High labor requirement amplitude was found to have a strong adverse effect on labor utilization while longer operational days were associated with improved labor utilization for all labor requirement distributions. We discuss the implications of these results for service operations management and provide suggestions for future research.  相似文献

At the time of the research, Khartoum was a multi-ethnic and multinational metropolis of 8 million people. A considerable part of the population consists of Southern Sudanese migrants and displaced persons that came during the 20 years plus of civil war in South Sudan to the capital. These people were categorised after the Comprehensive Peace Agreement (CPA), as displaced people regardless as to whether they come to the capital as labour migrants, students or because of the war to the capital. The notion of displacement assumes that they are people who are ‘out of place’: thereby assuming a former situation of being in place, a place that can be called ‘home’. After the CPA from 2005, this frequently only imagined home became a real place for the IDP’s to which they are supposed to go back. Yet, many migrants and displaced people are reluctant to move to Southern Sudan. Their decision about going to the South or staying in Khartoum depends not only on the opportunities and perspectives in their respective ‘home’ areas but also on the perceptions of belonging and identity. The imaginations and aspirations about the future life in South Sudan, which I analyse in this article, reflect this ambivalent positioning.  相似文献

There is general consensus that physical activity is important for preserving functional capacities of older adults and positively influencing quality of life. While accelerometry is widely accepted and applied to assess physical activity in studies, several problems with this method remain (e.g., low retest reliability, measurement errors). The aim of this study was to test the intra-instrumental retest reliability of a wrist-worn accelerometer in a 3-day measurement of physical activity in older adults and to compare different estimators. A sample of 123 older adults (76.5?±?5.1?years, 59?% female) wore a uniaxial accelerometer continuously for 1?week. The data were split into two repeated measurement values (week set) of 3?days each. The sum, the 80?C99th quantiles and the 80?C99th trimmed sums were built for each week set. Retest reliability was assessed for each estimator and graphically demonstrated by Bland?CAltman plots. The intraclass correlation of the retest reliability ranged from 0.22 to 0.91. Retest reliability increases when a more robust estimator than the overall sum is used. Therefore, the trimmed sum can be recommended as a conservative estimate of the physical activity level of older adults.  相似文献

This paper presents a tractable set of integer programming models for the days-off scheduling of a mix of full- and part-time employees working α to β days/week (cycle) in a multiple-objective, multiple-location environment. Previous models were formulated to specifically schedule part-time employees working either two or three days per week. These models were intractable because they required complete employee schedule information. The new models are deemed implicit optimal since they are required to supply only essential information. While the number of variables in previous models is an exponential increasing function of β-α, the size of three of the new models is independent of α and β. The first three models developed here (as in [18]) deal with the trade-offs between idle time, the number of employees required to work at multiple “locations,” and the size of the total labor pool. The inherent flexibility of the implicit modeling approach is illustrated by the presentation of various modifications of the basic models. These modifications permit the use of preference weights on the number of employee work days/week (cycle) or the minimization of payroll costs where differential pay rates exist. These latter models may also be formulated such that idle time is ignored, constrained or minimized. The execution time for the implicit models (on a CDC CYBER 730 computer with commercially available software) averaged well under five seconds on 1200 trial problems for the type of application considered in [18]. A solution was obtained in less than 46 seconds of CPU time for a trial problem which would have required over 1.4 million integer variables with previous models. The availability of optimal solutions was invaluable in the development of two heuristics designed to deal with the trade-offs of [16]. In an experimental analysis a previous heuristic produced results which averaged from 74 to 508 percent above optimum across six experimental conditions. The comparable new heuristic produced results which averaged from 3 to 8 percent above optimum for the same experimental conditions. The paper concludes by developing a framework to integrate the results of this research with the tour scheduling problem and by identifying several other areas for related research.  相似文献

Is there still something specific East German in the need for counseling? There is a specific East German background, considering the adaption of issues, contents and methods of counseling of East German top management, enterprises and institutions. In the last ten years, development in East Germany was above all a make up for the development of West German conditions. Today the trends in West and East Germany are equally faced with the reorganization of processes resulting from global standards. These are confronted with a hardly stabil economical and social basis in East Germany. The general need for counseling is determined by psychological counseling and change management.  相似文献

The article provides an overview of the results of cross-sectional and longitudinal data sets concerning sport participation of the elderly in Germany with a focus on correlations of sport participation with gender, age, and social class. A tabular overview lists the most central studies with their study design and publications from 2000 onwards. Findings regarding the motivations for sport participation of the elderly, the types of sport which are done, and the preferred settings are summarized. Eventually a conclusion is given about “what we know and what we don’t know.”  相似文献

Men and masculinity are considered a key factor in changing gender inequality at the transition to parenthood. Prior research on gendered division of parental leave concentrated on fathers’ perspectives. This paper includes perspectives of fathers and mothers who make use of parental leave in different ways and asks how masculinity is jointly constructed, how these constructions are linked to the use of parental leave, and if and how they are oriented towards hegemonic masculinity. The analysis is based on 44 qualitative interviews with 11 Austrian couples before and after birth when decisions concerning parental leave were made. Our case reconstructions reveal that parents considered parental leave a central element of masculinity as long as it suited fathers’ needs and circumstances permitted. The decisions for sharing parental leave were father-centred as both partners valued father’s leave higher than mother’s.  相似文献
