The relationship between employee motivation and psychological health at work: A chicken-and-egg situation?

Although employee motivation and psychological health at work have been found to be related, it remains unclear whether motivation precedes psychological health or vice versa, and to which extent different manifestations of mental health relate to different forms of motivation at work. Using the self-determination theory and the bidimensional theory of psychological health, this complete panel design study tested the directionality of the relationship between motivation at work and psychological health at work, with a dedicated focus on the specific predictive patterns observed between 4 types of motivation at work and positive and negative indicators of psychological health at work. Eight hundred and five Canadian workers completed questionnaires at 2 times, separated by a 6-month interval. Structural equation modelling analyses indicated that only identified regulation and psychological well-being at work have a fully reciprocal relationship. Only psychological well-being at work was positively associated with the 3 most self-determined types of motivation at work 6 months later, and only identified regulation predicted psychological health at work after 6 months. External regulation was unrelated to all indicators of psychological health at work over time. By integrating 2 theoretical frameworks, this study clarified the relationships between psychological health at work and motivation at work over time.     

Quantifying the Distribution of Inhalation Exposure in Human Populations: 2. Distributions of Time Spent by Adults, Adolescents, and Children at Home, at Work, and at School

Using distributions of time spent at various ventilation levels, ranges of inhalation exposure in the population can be established. Distributions of exposure time were determined using results of a study by the California Air Resources Board (CARB) which focused on time spent by humans participating in various activities and the locations where the activities occurred. The daily at-home activities from the CARB study were assigned to one of three ventilation levels, generating aggregate time periods. Distinct age and gender populations were identified, and distributions for aggregate time were established for these populations at each of the ventilation levels. In addition to aggregate time spent at home, distributions for various ages and genders were established for aggregate time spent at school and work. By combining distributions of aggregate time with corresponding ventilation rates, the distribution of inhalation rates can be established for at home, at work, and at school exposures.

Changes at Corporate Headquarters: Review,Integration and Future Research

In modern corporations, the corporate headquarters (CHQ) unit is considered central to the fortunes of the overall firm. In light of ever‐changing environments, changes at the CHQ have become a crucial concern in management research and practice, and scholars have studied a variety of changes at the CHQ. Despite the common focus on the CHQ entity and the potential for cross‐fertilization across several research tracks, a coherent picture of this dispersed body of knowledge is lacking. This paper reviews 25 years of research on changes at the CHQ. In so doing, it advances a common language and an overarching framework that integrates the existing knowledge in the intellectual domains of strategy, organizational design and international business research. On this basis, the authors suggest directions for future research to advance knowledge of: (1) the pressure for and resistance to changes at the CHQ; (2) interrelationships among changes at the CHQ; (3) change processes at the CHQ; (4) agents involved in changes at the CHQ; and (5) adaptive and disruptive effects of changes at the CHQ. Overall, the study provides a conceptual basis for combining the existing knowledge of changes at the CHQ and serves as a guide for future research.     

Personality factors predicting changes in shift work tolerance: A longitudinal study among nurses working rotating shifts

Abstract

The aim of the present study was to investigate the relationship between personality factors (hardiness, morningness, flexibility, and languidity) and longitudinal changes on different measures of shift work tolerance (fatigue, sleepiness, anxiety and depression) over one year among nurses working rotating shifts. A total of 642 female Norwegian nurses working in a rotating three-shift schedule participated in the study. The cohort was established by age-stratified selection among members of the Norwegian Nurses Association in 2008. Questionnaires were administered in 2008/2009 (T1) and in 2009/2010 (T2). The results showed that hardiness was negatively related to fatigue, anxiety and depression at T2 when controlling for the scores on these constructs at T1. Morningness was not related to any indicators of shift work tolerance at T2 when controlling for shift work tolerance at T1. Flexibility was negatively related to anxiety at T2 when controlling for anxiety at T1. Languidity was positively related to sleepiness and fatigue at T2 when controlling for sleepiness and fatigue at T1. The findings indicate that personality factors, especially hardiness, can predict changes related to shift work tolerance over a period of one year.     

One-Hit Models of Carcinogenesis: Conservative or Not?

One-hit formulas are widely believed to be "conservative" when used to analyze carcinogenesis bioassays, in the sense that they will rarely underestimate risks of cancer at low exposures. Such formulas are generally applied to the lifetime incidence of cancer at a specific site, with risks estimated from animal data at zero dose (control), and two or more additional doses that are appreciable fractions of a maximum tolerated dose. No empirical study has demonstrated that the one-hit formula is conservative in the sense described. The Carcinogenesis Bioassay Database System contains data on 1212 separate bioassays of 308 chemical substances tested at exactly three evaluable doses. These provided sufficient data to examine 8432 specific combinations of cancer site with sex, species, and chemical. For each of these we fitted a one-hit formula to the zero and maximum dose data points, then examined the relation of the fitted curve to the incidence rate observed at the mid-dose, with and without adjustment for intercurrent mortality. Both underestimates and overestimates of risk at mid-dose occurred substantially more often than expected by chance. We cannot tell whether such underestimates would occur at lower doses, but offer six biological reasons why underestimates might be expected. In a high percentage of animal bioassays, the one-hit formula is not conservative when applied in the usual way to animal data. It remains possible that the one-hit formula may indeed be conservative at sufficiently low doses (below the observational range), but the usual procedure, applied to the usual dose range, can be nonconservative in estimating the slope of the formula at such low doses. Risk assessments for regulation of carcinogens should incorporate some measure of additional uncertainty.     

Toward a Differentiated Understanding of the Value‐Creation Chain

The conventional view of the value‐creation chain suggests offering high‐value propositions at the product level (in terms of benefits provided by elements of the product) to attain high‐value perceptions at the customer level, which should ultimately result in high‐value appropriation at the firm level (i.e. relationship, volume, pricing and financial success). This study challenges this view and provides a differentiated understanding of the value‐creation chain. With a multi‐industry sample of 339 companies and a sample of 626 customers to validate managerial assessments, the authors apply a configurational approach to identify whether and to what extent offering high‐value propositions at the product level is necessary or sufficient for achieving superior value perceptions at the customer level and high‐value appropriation at the firm level. Taking into account the company‐internal and company‐external environment of the value‐creation chain, the study identifies seven value‐creation chain constellations.     

Professional vitality and career success: Mediation,age and outcomes

We propose a model that explains the complex phenomenon of successful career at work, and focuses on the antecedents of professional vitality at the workplace. The model sheds light on the role of professional vitality as an essential ingredient for successful careers. Using a survey design, we tested our model with a sample of 545 managers and professionals. The findings suggest effects of career attitudes on career outcomes, mediated by professional vitality. The relationship between professional vitality and age at work environment forms an inverse U shape curve, peaking at age of fifties, an optimistic note for the global aging workforce.     

Integration of disciplines for applied scheduling: a workshop report

The purposes of this paper are, first, to introduce several concepts and definitions related to Theory of Constraints design and management of unbalanced lines and, second, to illustrate the concepts of productive and protective capacity and inventory in a constrained line. Drum-buffer-rope is the Theory-of-Constraints based scheduling mechanism used to manage throughput at constraint work stations and flow at non-constraint work stations. A small simulation model is given to illustrate the importance of protective capacity and protective inventory at non-constraint stations. The line consists of several stations with the centre station being the constraint station. The capacity of (and inventory at) non-constraint stations is varied during the simulation. Line output increases as inventory at non-constraint stations increases. This result is contrary to traditional teaching about line design which says that line output is a function solely of the capacity of the slowest station.
