Examining the Relationships Between the Justice Facets and Turnover Intent: The Mediating Roles of Overall Justice and Psychological Strain

We examined how interpersonal justice from coworkers, the traditional justice facets (i.e., distributive, procedural, interpersonal, informational), and overall justice perceptions relate to employee psychological strain and turnover intentions in Canadian Armed Forces personnel. Specifically, we hypothesized that overall justice would mediate the relationships between the justice facets (including coworker justice) and strain, and strain would mediate the relationship between overall justice and turnover intent. We used a cross-sectional correlational design with personnel from 2 military units (total N = 218) as our sample. A 2-step structural equation modeling technique was used to evaluate our hypotheses. Support for our hypotheses was obtained with 1 exception: informational justice did not predict overall justice judgments. Our results suggest that employees’ reactions to individual justice events and different sources of justice exert their effects on strain and turnover intent indirectly through their impact on a global evaluation of justice in their work environment.     

Marital role strain,illness intrusiveness,and their impact on marital and individual adjustment in end-stage renal disease

Abstract

A marital role theory approach was used to investigate individual psychosocial well-being and marital adjustment in 89 end-stage renal disease (ESRD) patients and their spouses. Four different patient groups were selected according to a continuum of clinical milestones in the treatment of ESRD, including pre-dialysis (n=17), incenter dialysis (n=18), home dialysis (n=19), and posttransplant patients (n=17). A nephrology clinic control group (n=18) was also included. Standardized instruments were employed to investigate marital role strain (Marital Role Questionnaire, KDS-15), marital adjustment (Locke-Wallace Marital Adjustment Test), subjective well-being (Affect Balance Scale, Rosenberg Self-Esteem Inventory), and psychopathology (Symptom Checklist 90-R). Hierarchical multiple regression analyses provided strong and consistent support for the major hypotheses relating elevated marital role strain to compromised marital adjustment and individual well-being. Further analyses demonstrated that increased perceived intrusiveness of ESRD was significantly related to greater marital role strain, poorer marital adjustment, and decreased individual well-being. This is consistent with the idea that perceived intrusiveness may be an important mediator of marital role strain and of coping with chronic illness. “Objective” intrusiveness, defined in terms of patient group, was not significantly related to marital or individual well-being. These findings support a dyadic approach to the psychosocial study of chronic illness.     

The job demand-control(-support) model and physical health outcomes: A review of the strain and buffer hypotheses

Abstract

This review of the Job Demand-Control (JDC) model and the expanded Job Demand-Control-Support (JDCS) model and employees' physical health, focuses on the two prevalent views on these models. According to their view on the models researchers study different hypotheses: (a) the (iso)strain hypothesis, stating that the highest level of ill health is expected when the job is characterized by high demand and low control (and low social sup port), ot (b) the buffer hypothesis, predicting that control (and social support) can buffer the potential negative effects of high demands on physical health. It is argued that these hypotheses reflect theoretical distinct models, and that the practical implications associated with these models differ.

The review of 51 studies on the JDC(S) model reveals that the “strain” hypothesis predominates in studies of all-cause mortality, cardiovascular disease (CVD) related and specific non-CVD related health outcomes. In contrast, the “buffer” hypothesis is most prevalent in research on self-reported (psycho)somatic complaints. For the strain hypothesis as well as the buffer hypothesis the results are equivocal. Working in a high (iso)strain job appears to be associated with an elevated risk for cardiovascular disease and negative pregnancy outcomes, and increased (psycho)somatic complaints. Conclusions on other physical outcomes seem premature, considering the limited number of studies. The buffer hypothesis is supported in the few studies on CVD endpoints and in some studies on (psycho)somatic complaints.

A comparison of the validity of the two hypotheses is problematic, because they are mostly applied to a different set of outcomes. Furthermore, the analyses employed in the testing of the two hypotheses are of a different nature (non-linear versus linear).

The main recommendation for future research is to examine the validity of the strain and the buffer hypothesis concurrently, and to further explore the nature of the relationships.     

Work strain and the post-discharge adjustment of patients following a heart attack

Abstract

The role of work characteristics in determining return to work after an acute coronary event was examined. One hundred and forty nine patients were enrolled. One year post-discharge, 74 had returned to work. Work characteristics (decision latitude, and opportunity for social interaction at work), together with age, depression, and medical prognosis, correctly classified work status in 78% of cases. At 12 months post-discharge, patients who had not returned to work recorded significantly poorer levels of adjustment compared to those who had returned to work. A better quality of life is associated with a lower level of depression pre-hospitalization, ownership of a larger home, being male, and having a more positive work environment. The findings suggest that the pre-illness work environment of the patient is a factor influencing return to work, which needs to be considered in rehabilitation programmes.     

Supersonic crack motion in a harmonic lattice

Antiplane shear cracks in a harmonic square lattice have been studied in a molecular dynamics simulation. They can reach velocities larger than the shear wave velocity.     

Electromechanical behavior of single-walled carbon nanotube thin films

Carbon nanotubes have been intensively studied owing to their great potential in nanoelectronics and nanomechanical devices. Recently, experimental results have shown that single-walled carbon nanotubes (SWCNTs) change their electronic properties when subjected to strain. In this study, the electromechanical characteristics of SWCNT networks were investigated for the application of printable strain sensors on flexible substrates. SWCNT films were formed on plastic substrates of poly(ethylene terephthalate) using a spray process. In this manner, we were able to control the transparency and obtain uniform electrical properties of the films. The films are isotropic on account of the random orientation of bundles of SWCNTs. Experimental results showed a nearly linear change in the resistance across a film when it was subjected to tensile strain, even in the inelastic range of the flexible substrate. The results demonstrate the potential use of SWCNT films for highly sensitive printable strain sensors on a macroscale.     

Work stress,work–home interference and perceptions of organisational culture amongst insurance employees in Zimbabwe

The objective of the study was to determine the relationship between work stress, work-home interference, and perceptions of organisational culture amongst insurance employees in the Zimbabwean context. Data were collected from a sample of 190 employees (females=46%) who completed the Occupational Stress Inventory-Revised (OSI-R), the Work-Home Interference Questionnaire (SWING), and the Organisational Culture Index (OCI). Data analysis consisted of correlational and standard multiple regression analyses. The results revealed significant positive correlations between the sub-scales Role Overload, Role Insufficiency, Role Ambiguity, Role Boundary, Responsibilities, and Physical Environment of the OSI-R, the sub-scales Positive Work-Home Interference and Negative Work-Home Interference of the SWING, and the sub-scales Bureaucratic, Innovative and Supportive Culture of the OCI. These findings contribute to new knowledge in terms of the work stress experienced by insurance employees who are always under continuous pressure from the industry. Furthermore, it could be used to gain insight to enhance the work-life balance of insurance employees and the effect of organisational culture as perceived by insurance employees.     

Psychological state and psychological strain in relation to infertility

The purpose of the study was to explore the relationship between psychological state and perceived strain in relation to fertility problems. Couples presenting at an infertility clinic completed, on two occasions seven months apart, a series of standardized measures to assess psychopathology. In addition, they completed a weekly diary rating their mood state or distress/strain over a period of 22 weeks, during which investigations and treatment were taking place. Little evidence of psychopathology was found in the sample; the weekly diaries also suggested a general lack of distress/strain, even in response to medical investigations and diagnosis. The results are discussed in the light of wide individual variations in ratings obtained from the diaries. Participants with high distress/strain scores tended to have significantly higher initial scores on the psychometric measures administered. Participants with high distress/strain scores were also more likely to show a further significant increase in distress/strain scores in relation to diagnostic information. It is argued that a task for future research is to determine the characteristics of those couples who are likely to experience difficulty in coping with the strain of infertility investigations so that counselling resources and support services can be most effectively targeted. © 1998 John Wiley & Sons, Ltd.     

The influence of number line estimation precision and numeracy on risky financial decision making

This study examined whether different aspects of mathematical proficiency influence one's ability to make adaptive financial decisions. “Numeracy” refers to the ability to process numerical and probabilistic information and is commonly reported as an important factor which contributes to financial decision‐making ability. The precision of mental number representation (MNR), measured with the number line estimation (NLE) task has been reported to be another critical factor. This study aimed to examine the contribution of these mathematical proficiencies while controlling for the influence of fluid intelligence, math anxiety and personality factors. In our decision‐making task, participants chose between two options offering probabilistic monetary gain or loss. Sensitivity to expected value was measured as an index for the ability to discriminate between optimal versus suboptimal options. Partial correlation and hierarchical regression analyses revealed that NLE precision better explained EV sensitivity compared to numeracy, after controlling for all covariates. These results suggest that individuals with more precise MNR are capable of making more rational financial decisions. We also propose that the measurement of “numeracy,” which is commonly used interchangeably with general mathematical proficiency, should include more diverse aspects of mathematical cognition including basic understanding of number magnitude.
