An optimal level of dust explosion risk management: Framework and application

The current research provides guidance on the prevention and mitigation of dust explosion using a Quantitative Risk Management Framework (QRMF). Using concepts drawn from previous studies, the framework consists of three main steps: (i) a new combined safety management protocol, (ii) the use of DESC (Dust Explosion Simulation Code) and FTA (Fault Tree Analysis) to assess explosion consequences and likelihood, respectively, and (iii) application of the hierarchy of controls (inherent, engineered and procedural safety). QRMF assessment of an industrial case study showed that the original process was at high risk. DESC simulations and Probit equations determined the destructive percentages. FTAs revealed high probabilities of explosion occurrence; in addition, detailed individual and societal risks calculations were made, before and after the framework was applied. Based on the hierarchy of controls technique, the framework showed significant risk reduction to the point where the residual risk was acceptable for the process.     

Accuracy in job analysis: toward an inference‐based model

Although the accuracy of job analysis information is critically important, standards for accuracy are not clear. Researchers have recently begun to address various aspects of job analysis accuracy by investigating such things as potential sources of inaccuracy in job analysis as well as attempting to reconceptualize our notions of job analysis accuracy. This article adds to the debate by first discussing how job analysis accuracy has been conceptualized. This points to difficulties in the prevalent ‘true score’ model upon which many of these discussions have been based. We suggest that discussions of job analysis accuracy would benefit from a consideration of the validity of job analysis inferences, as a complement to the more traditional focus on the validity of job analysis data. Toward this end, we develop a model of the inferences made in the job analysis process, outline some of the ways these inference could be tested, and discuss implications of this perspective.

Reducing the risk level for pipelines transporting carbon dioxide and hydrogen by means of optimal safety valves spacing

In many countries where electricity generation is based on their natural resources of fossil fuels a need arises to implement new power engineering technologies that allow carbon dioxide capture. Simultaneously, efforts are made to find new energy carriers which, if fired, do not involve carbon dioxide emissions. Hydrogen is one of such fuels with this future potential which is now becoming increasingly popular. Obviously, this means that the two gases mentioned above – carbon dioxide and hydrogen – will be produced in large quantities in future, which in many cases will necessitate their transport over considerable distances. If a pipeline failure occurs, the transport of the gases may pose a serious hazard to people in the immediate vicinity of the leakage site. This paper presents an analysis of the possibility of reducing the level of risk related to pipelines transporting CO₂ and H₂ by means of safety valves. It is shown that for a 50 km long and a 0.4 m diameter pipeline transporting gas with the pressure of 15 MPa the individual risk level can be reduced from 1·10⁻⁴ to 6.5·10⁻⁷ for CO₂ and from 1·10⁻⁶ to 6·10⁻¹⁰ for H₂. The social risk can be diminished in similar proportions.     

Reorienting job crafting research: A hierarchical structure of job crafting concepts and integrative review

Two dominant perspectives of job crafting—the original theory from Wrzesniewski and Dutton ( 2001 ) and the job demands resources perspective from Tims, Bakker, and Derks ( 2012 )—remain separate in research. To synthesize these perspectives, we propose a three‐level hierarchical structure of job crafting, and we identify the aggregate/superordinate nature of each major job crafting construct. The first level of the structure is job crafting orientation, or approach versus avoidance crafting, which we argue is an essential yet often neglected distinction in the literature. We address the debate surrounding cognitive crafting and identify crafting form (behavioral versus cognitive crafting) as the next hierarchical level of constructs. Finally, we concur that job resources and job demands, or crafting content, capture different ways that individuals craft their jobs. Using this integrated hierarchical structure, we were able to review antecedents and outcomes from both perspectives. We show, for example, that approach crafting in its behavioral form is very similar to other proactive behaviors in the way it functions, suggesting a need for closer synthesis with the broader proactive literature, whereas avoidance crafting appears to be less proactive and often dysfunctional. On the basis of our review, we develop a road map for future research.     

Predicting applicants' job pursuit behavior from their selection expectations: the mediating role of the theory of planned behavior

Applicants' pretest expectations about the forthcoming selection procedure may serve as a key factor in applicants' decision‐making. The current study examined the validity of the theory of planned behavior (TPB) as an explanatory mechanism of the relationship between pretest selection expectations (warmth/respect, chance to demonstrate potential, difficulty of faking, unbiased assessment, feedback) and job pursuit behavior. Data were collected at two points in time, using a sample of applicants for the military. Selection expectations, job pursuit attitude, subjective norm, and controllability were significantly related to job pursuit intention. Job pursuit attitude mediated the relationship between selection expectations and job pursuit intention. Subjective norm and time lag were the only significant predictors of job pursuit behavior. Practical implications, strengths and limitations, as well as directions for further research are discussed. Copyright © 2008 John Wiley & Sons, Ltd.     

Occupational stress in (inter)action: the interplay between job demands and job resources

The present study addresses theoretical issues involving different interaction effects between job demands and job resources, accompanied by a thorough empirical test of interaction terms in the demand–control (DC) model and the effort–reward imbalance (ERI) model in relation to employee health and well‐being (i.e., exhaustion, psychosomatic health complaints, company‐registered sickness absence). Neither the DC model nor the ERI model gives a clear theoretical rationale or preference for a particular interaction term. Hierarchical regression analyses were conducted among 405 nursing home employees and cross‐validated in a comparable sample (N = 471). Results including cross‐validation showed that only a multiplicative interaction term yielded consistent results for both the DC model and the ERI model. Theoretical as well as empirical results argue for a multiplicative interaction term to test the DC model and the ERI model. Future job stress research may benefit from the idea that there should be a theoretical preference for any interaction form, either in the DC model or in the ERI model. However, more research on interactions is needed to address this topic adequately. Copyright © 2005 John Wiley & Sons, Ltd.     

Daily performance at work: feeling recovered in the morning as a predictor of day‐level job performance

This study examined the state of being recovered in the morning (i.e., feeling physically and mentally refreshed) as a predictor of daily job performance and daily compensatory effort at work. Ninety‐nine employees from public service organizations completed a general survey and two daily surveys on pocket computers over the course of one workweek. Hierarchical linear modeling showed that being recovered in the morning was positively related to daily task performance, personal initiative, and organizational citizenship behavior and negatively related to daily compensatory effort at work. Relationships between the state of being recovered and day‐specific job performance were moderated by job control. For persons with a high level of job control, the relationship between being recovered and daily performance was stronger. Copyright © 2008 John Wiley & Sons, Ltd.     

Recovery from job stress: The stressor‐detachment model as an integrative framework

This paper reviews empirical evidence on psychological detachment from work during nonwork time. Psychological detachment as a core recovery experience refers to refraining from job‐related activities and thoughts during nonwork time; it implies to mentally disengage from one's job while being away from work. Using the stressor‐detachment model as an organizing framework, we describe findings from between‐person and within‐person studies, relying on cross‐sectional, longitudinal, and daily‐diary designs. Overall, research shows that job stressors, particularly workload, predict low levels of psychological detachment. A lack of detachment in turn predicts high strain levels and poor individual well‐being (e.g., burnout and lower life satisfaction). Psychological detachment seems to be both a mediator and a moderator in the relationship between job stressors on the one hand and strain and poor well‐being on the other hand. We propose possible extensions of the stressor‐detachment model by suggesting moderator variables grounded in the transactional stress model. We further discuss avenues for future research and offer practical implications. Copyright © 2014 John Wiley & Sons, Ltd.     

Implications of job insecurity perceptions and job insecurity responses for psychological well-being,turnover intentions and reported risk behavior

This study aimed to test whether cognitively appraised level of job insecurity (job insecurity perceptions) and evaluative responses to a perceived level of job insecurity (job insecurity dissatisfaction and job insecurity behaviors) could relate differently to employee mental well-being, turnover intentions and on-the-job risk behavior. The significance of demographic characteristics (gender and age) as well as the implications of attitudinal variables (job satisfaction, job motivation and organizational commitment) and for the dependent variables was taken into account. Based on data from a self-completion questionnaire survey carried out among a representative sample of the Norwegian adult population (N = 260) results indicated that only job insecurity behaviors were indirectly related to turnover intentions and risk behavior via their impact on psychological well-being. The relative importance of the job insecurity dimensions for the dependent variables are discussed, as well as theoretical and practical implications.     

Environmental disaster education at the university level: an integrative approach

Because of the highly complex nature of chemical and nuclear accidents, efforts aimed at prevention, preparedness and response require the melding of many types of knowledge and the close collaboration of a wide range of professions. Nevertheless, the need for such integration and cooperation is not always strongly emphasized in university-level curricula. As a result, developing professionals have few opportunities to learn and practise unified models of environmental accident management. In an effort to foster a more integrative approach, the University of Alabama at Birmingham, USA, has launched the “Environmental Disasters” project. The project crosses disciplinary boundaries with respect to both curriculum and enrollment. In terms of curriculum, the project examines chemical and nuclear accidents from a multi-dimensional perspective, considering not only regulatory, scientific and policy issues, but also the public health, social, and psychological implications. In terms of enrollment, the project brings together students from the full range of fields that are involved with environmental accidents, including engineering, public health, public administration, social work, psychology, nursing, communications, medicine, and environmental studies. Emphasizing the need for a collaborative approach, students work in multi-disciplinary teams as they explore theory, case studies and current research. In addition, the student teams develop detailed plans for addressing the effects of a chemical or nuclear disaster. With environmental accidents representing an on-going threat to health and safety, the approach discussed in this article may provide a useful model for environmental disaster education at the university level.     

Coping with job stress: A conceptual evaluation framework for coping measures

Intense interest in stress had led to a proliferation of coping measures. To aid researchers in choosing or developing coping measures applicable to job stress, this paper provides a conceptual evaluation framework. The framework serves to evaluate the extent to which coping measures are comprehensive (focus and method of coping) and specific (coping behaviors versus coping effectiveness, coping style, or coping resources; and stress management applications). Both theoretical and organizational stress management perspectives are incorporated.     

Personality and job performance: the importance of narrow traits

In a recent discussion of the bandwidth–fidelity dilemma in personality measurement for personnel selection, Ones and Viswesvaran (1996) concluded that ‘broader and richer personality traits will have higher predictive validity than narrower traits’. In this paper, the arguments made by Ones and Viswesvaran in favor of the exclusive use of broad personality dimensions are discussed. New data are presented that contradict Ones and Viswesvaran's claim of the existence of a general, integrity-related personality factor, and that show two narrow measures—the Responsibility and Risk Taking scales of the Jackson Personality Inventory—to have higher validities than the Big Five dimensions with respect to job performance criteria based on self-reported workplace delinquency in a sample of 127 entry-level employees. © 1998 John Wiley & Sons, Ltd.     

The dispositional approach to job satisfaction: more than a mirage,but not yet an oasis

This paper readdresses the person–situation debate in organizational research. The well‐known arguments of Davis‐Blake and Pfeffer (1989) are evaluated in light of research and theory that has transpired since the publication of their original critique. A new dispositional model of job satisfaction is then proposed. The model is based on several informational and action steps including exposure to work events and condition, as well as the evaluation, memory, retrieval, and expression of affect in the organizational context. Using this model, we discuss how dispositional affect can influence what is experienced in the workplace, how one evaluates it, and how it is expressed to others, including organizational researchers.

Satisfaction at last job and unemployment: a new look

Based on interview studies, the unemployment literature suggests that last job satisfaction influences reactions to unemployment. This study assessed the quantitative relationship between last job satisfaction and the unemployment experience. Results do not support the literature's premise that high last job satisfaction predicts a negative reaction to unemployment. Copyright © 1999 John Wiley & Sons, Ltd.     

Work-Family conflict: The effect of job and family involvement

A review of past research revealed inconsistent findings concerning the relationship between job involvement and work-family conflict. This study tested whether family involvement moderates the relationship between job involvement and work-family conflict. Two types of family involvement (spouse and parent) and two types of work-family conflict (job-spouse and job-parent) were assessed. Data were gathered via questionnaire from a sample of nonteaching professionals employed by a large public university in the northeastern United States. As hypothesized, job involvement and job-spouse conflict were positively related for individuals high in spouse involvement and unrelated for individuals low in spouse involvement. Contrary to prediction, parental involvement did not moderate the relationship between job involvement and job-parent conflict. Instead, job involvement was positively related to job-parent conflict regardless of the level of parental involvement. Results are discussed in terms of standards for role performance and strength of role demands. Implications for future research are also discussed.     

A new conceptualization of union commitment: Development and test of an integrated theory

An introductory conceptual and empirical review stresses the need for a stable theoretical basis for union commitment research. The purpose of this paper is to develop a new conceptualization of union commitment based on the integration of two theories (the theory of reasoned action and the rationalistic approach to commitment). The integrated theory suggests that union commitment is composed of two dimensions, one based on instrumentality and one based on ideology, which are causally related to prounion behavioral intentions and, in turn, to union participation. Propositions derived from the integrated theory are tested using data on 1486 blue-collar workers in Sweden. Results of linear structural equation modelling with latent variables and of multiple regression analyses provide strong support for the construct validity of the commitment dimensions and the overall applicability of the integrated theory. The central findings, their conceptual implications for the understanding of union commitment, and their practical implications for unions are discussed.     

Industrial relations stress and job satisfaction: Concurrent effects and mediation

We examine the effects of negative and positive industrial relations stress on both mood (negative and positive) and job satisfaction. Twenty industrial relations practitioners completed daily reports of industrial relations stress, mood, and job satisfaction over a 20-day period. After controlling for serial correlation, negative industrial relations stress affected negative mood and, in turn, job satisfaction. Positive industrial relations stress had direct effects on both positive mood and job satisfaction with positive mood also affecting job satisfaction. All effects were concurrent with no next-day effects of stress on mood or job satisfaction. Further research on industrial relations stress is both warranted and encouraged.     

A Management of change approach for assessing and Evaluating operational Staffing Levels (MocESL) in chemical plants

Chemical enterprises are often challenged with efficiently assessing their operational staffing levels. Unbalanced and inadequate manning levels might be financially adversarial and may even lead to (minor and major) accidents. This paper provides a framework and a roadmap to assist chemical plants in assessing and evaluating their operational staffing levels. The approach can be implemented within the entire organization or within a part thereof (i.e., a business unit or an installation). As a part of the suggested approach, an instrument is provided for evaluating operational staffing levels as they currently exist within a chemical company, business unit, or installation.
