Abstract

Purpose

Presently, there are two main classification of architectural courses in the curriculum: lecture courses and design studios. Owing to the duality between design studios and lecture courses, architectural education includes a highly stressful learning environment. In addition to this dualism, architecture students also cope with their lives in universities and different types of stressors similar to all university students. Therefore, this study aims to determine the critical stress factors that affect architecture students studying in Turkey.

Design/methodology/approach

The reasons for a stressful architecture learning environment were examined using a questionnaire distributed among architecture students, and face-to-face surveys were conducted. The obtained data were analysed statistically using SPSS 22 and LISREL 8.7 software. Correlation analysis, exploratory and confirmatory analysis and structural equation modelling of the relationships between the stressors and stress factors and the impacts (perceived stress) were performed, and a structural model was developed.

Findings

A total of 11 critical factors affecting architecture students’ stress levels were determined; academic inadequacy, unusual assessments and evaluation techniques of courses and intensive academic schedule were the most critical stressors. Based on these factors, necessary solutions and recommendations were offered, which are expected to decrease architecture students’ stress levels and encourage other similar studies.

Originality/value

There is limited research that provides insights into the factors that cause stress to architecture students; only literature reviews and surveys are currently available. Unlike these, this study presents a structural equation model for critical stress factors via a confirmatory factor analysis.

Abstract

Purpose

The purpose of this paper is to study the mechanical property of three-dimensional (3D) Printed photopolymer (Vero Yellow and Tango Black) with different constant strain rate. According to the experimental results, three constitutive models are used to describe the stress-strain and stress-time relation in the tension and stress relaxation process.

Design/methodology/approach

The Stratasys Objet 260 was used to prepare the four groups of samples with different photopolymers (Vero Yellow and Tango Black). The stress-strain and stress-time relations are obtained by the uniaxial tensile tests and relaxation tests performed at room temperature with different constant strain rates. The generalized Kelvin model (GKM), standard linearized model (SLM) and fractional order model (FOM) are used to describe experimental data by means of the curve-fitting approach.

Findings

Experimental results show that the tension stress increases faster at a higher strain-rate for tensile tests. Relaxation stress is influenced by the preload strain-rate for relaxation tests. For the theoretical fitting, the error comparison between three constitutive models and experimental data are calculated to demonstrate the high accuracy in describing the stress-strain relationship for tension. For stress relaxation, the error comparison confirms higher accuracy of FOM with the largest error within 3%, while the error of GKM and SLM up to 10%.

Originality/value

The paper confirms the viscous-elastic mechanical property of 3D printed photopolymer composites (Vero Yellow and Tango Black) for Stratasys PolyJet. As FOM shows high accuracy both in describing stress-strain and stress-time relation for tension and stress relaxation process, it can be directly used as a constitutive model to predict mechanical properties for engineering application.

Abstract

Purpose

While a return to work following trauma exposure can be therapeutic, this is not always so. As with many topics related to traumatic stress in organizations, several contingency factors complicate the effort to draw an overarching conclusion about whether returning to work is therapeutic. The purpose of this paper is to present important determinants of whether work is therapeutic or triggering for those with traumatic stress conditions. The need for contingency approaches in the study of traumatic stress in organizations is illustrated.

Design/methodology/approach

Literature on traumatic stress in organizations is reviewed.

Findings

Three of the key determinants of whether a return to work is therapeutic or triggering for traumatic stress sufferers are trauma-type contingencies, condition-type contingencies and work-setting contingencies. For instance, human-caused and task-related traumas are more likely than natural disasters to make a return-to-work triggering. Additionally, the time since developing a traumatic stress condition is inversely related to the degree of improvement in that condition through the experience of working. Moreover, managerial actions can affect how therapeutic an employee’s return to work is.

Practical implications

These findings suggest the challenges of reintegrating a traumatized employee to the workplace can be highly situation-specific. Careful consideration of the traumatic event suffered by each traumatic stress victim, their traumatic stress condition, and the work setting to which they would return are recommended.

Social implications

Promoting mental health in organizations can contribute to employers’ social performance.

Originality/value

Examination of the factors that complicate predicting whether work is therapeutic posttrauma demonstrates how contingency approaches can advance research on trauma in organizations.

Abstract

Purpose

This study investigates the relationship between police officer's willingness to use Employee Assistance Program (EAP) and their perceptions about stress and help-seeking in policing, considering the effect of gender and ethnicity in this association.

Design/methodology/approach

A survey of 431 Illinois police officers is used to measure officer's perceptions about help-seeking and organizational stressors. The conditional PROCESS modeling (Hayes, 2012) was employed to analyze the hypothesized mediation model. The ANOVA test was used to determent the effect of gender and ethnicity on organizational stressors in policing.

Findings

Findings suggest police officer's willingness to use EAP is shaped by the perceived negative effect of stress on promotion through the mediator, confidence in their departments to receive adequate assistance, with noticeable gender and ethnic differences. The analysis demonstrated that female police officers feel stressed because of unfair promotional opportunities and poor relationships with supervisors. Female police officers are less willing to apply for the EAP services to mitigate stress than male police officers. The findings reveal that ethnicity is a significant predictor of the police officers' willingness to apply for EAP services to mitigate stress.

Research limitations/implications

The current study is limited by its focus on only one police department located in the Illinois, USA. This may limit the generalizability of the results. The cross-sectional nature of data used to draw conclusions and variation in departments' characteristics and compositions could influence results.

Practical implications

The research has practical implications for those who are interested to understand organizational stressors and perceptions on help-seeking in policing. This study provides suggestions for police administrators to make effort in creating more sensitive working environment to reduce stressors for female police officers and representatives of ethnic groups.

Originality/value

The research unveils the significance of officer's confidence in their departments in modifying their willingness to use EAP, revealing the effect of organizational stressors on confidence. The study adds empirical evidence to existing research on impact of gender and ethnicity on their willingness to use EAP.

Abstract

Purpose

Elastic stress solutions are required in the field of fracture mechanics and the analysis of creep failure. The published precise elastic solutions are not addressing the influence of the manufacturing process induced, inevitable cross sectional deviations called ovality and thinning. The influence of ovality on plastic limit and collapse loads are reported in literature. Hence, it is important to study the combined effect of ovality and thinning on elastic stresses of bends.

Design/methodology/approach

This paper relies on elastic finite element evolutions of stress components– longitudinal membrane stress, longitudinal bending stress, circumferential membrane stress and circumferential bending stresses. Based on the results, the coefficients for the equations are also obtained through the regression analysis.

Findings

New analytical solutions are prescribed to estimate the elastic stresses at the mid-section of the 90° very thin-walled bend with ovality and thinning, when subjected to in-plane bending moment. The ovality has significant influence on elastic stress whereas the thinning is not so. The proposed equations give an accurate estimation of elastic stresses at the mid-section of the bend with the incorporation of the parameters, namely R/rm, rm/t and ovality.

Research limitations/implications

The influence of shape imperfections, namely ovality and thinning on elastic stress of 90° very thin-walled bends having rm/t > 20, subject to in-plane bending moment is proposed.

Originality/value

The influence of shape imperfections, namely ovality and thinning, on elastic stress of 90° very thin-walled bends with rm/t > 20, subject to in-plane bending moment is proposed.

Abstract

Purpose

Negotiations are often conducted under stress. Previous studies show that stress can help or hurt negotiation outcomes. This study suggests that individual differences explain these effects, and the purpose of this study is to examine the effect of social value orientation (SVO) and stress on negotiation outcomes.

Design/methodology/approach

Two experimental studies and a pilot investigate the influence of stress and SVO (prosocial vs proself) on negotiation offers and outcomes. The authors’ studies are grounded on social interdependence theory and arousal literatures to explain the effects of stress on negotiation.

Findings

Stress has a positive influence on integrative offers (S1) and joint outcomes (S2). SVO moderates the effect of stress on joint negotiation outcomes (S2), such that, under stress, prosocials fare better than proselfs.

Research limitations/implications

Managers negotiating under stress should pay attention to their own as well as the others’ SVOs. Managers could also build their negotiation teams considering this individual difference and favor the presence of prosocials in stressful negotiations.

Practical implications

The findings have practical implications for managers who are under stress on a daily basis.

Social implications

This research contributes to managers that need to understand how to reach integrative agreements under stress. This is especially important when negotiators are representatives of employees or companies, as the outcomes can affect many individuals.

Originality/value

To the best of the authors’ knowledge, this is the first study examining the relationship between stress, SVO and negotiation offers and outcomes.

Abstract

Purpose

The purpose of this study is (1) to confirm the relationship between the two dimensions of social desirability (pretending and denying), self-reported stress and health reports in police officers and (2) to assess whether dysfunctions in basal cortisol profiles are related to social desirability.

Design/methodology/approach

Social desirability is known to influence how individuals respond to sensitive topics, such as questions concerning health in the workplace, and has usually been defined according to two dimensions: pretending and denying. However, it is not known whether social desirability is only a bias in responding to health surveys or a more general attitude of denying problems and pretending to be stronger than one is in the everyday life. If the latter is true, social desirability may have important health implications, and underlying mechanisms must be described. In total, 77 police officers completed questionnaires measuring social desirability (denying and pretending), perceived stress as well as mental and somatic health symptoms. They were further instructed to collect saliva samples for cortisol concentrations assays.

Findings

These preliminary results showed that denying was negatively related to the report of stress and health symptoms. Furthermore, police officers higher in pretending showed a flatter diurnal cortisol slope.

Research limitations/implications

The correlation between dysregulation of the hypothalmic-pituitary-adrenal (HPA) axis, as expressed by a flatter cortisol slope, and a higher score in the pretending subscale suggests that looking for social approval by inflating one's capacities is related to chronic work-related stress, making the individual more vulnerable to stress-related disease.

Originality/value

To study the potential health-relevant consequences and underlying mechanisms of social desirability bias related to police culture by including stress biomarkers.

Abstract

Purpose

To add to the existing body of knowledge on the relationship between stress and job performance in policing, we monitored police officers' physiology using Hexoskin shirts while they responded to simulated scenarios.

Design/methodology/approach

We employed mixed repeated measures (baseline, intervention, post-intervention), between groups (treatment vs control group) design. Using this approach, our aims were (1) to determine whether an individualized physiological stress profile—a combination of heart rate (HR), heart rate variability (HRV), sympathetic nervous system (SNS) index and parasympathetic nervous system (PNS) index—could be developed for each participant; (2) to investigate the association between physiological stress and scenario performance and (3) to pilot test an intervention for decreasing physiological stress in real time.

Findings

We found that it was possible to individualize physiological stress profiles for each participant that alerted us when the participant was becoming stressed. We also found that physiological stress was significantly and negatively/inversely associated with scenario performance. However, our intervention to try and decrease participants' stress in real time was not successful. Several key lessons can be taken from our attempt that could inform future efforts in this area.

Research limitations/implications

This was a small pilot study, precluding generalizability of results. Furthermore, our intervention was simplistic and potentially affected by an experimenter effect. Future research should explore better ways to intervene when officers are becoming physiologically stressed to help them overcome stress in real time and safeguard against the cumulative effects of stress on health and performance.

Originality/value

This research adds to the body of knowledge on physiological stress and job-task performance in police officers.

Abstract

Purpose

The aim of this paper is to examine the effects of the disconfirmation of expectations of crowding and mall accessibility, on stress and two marketing outcomes, satisfaction and promoter scoring.

Design/methodology/approach

Data were obtained through two face-to-face surveys from mall shoppers that answered them at two different moments of their shopping experience, before entering the mall and before leaving it. Results are obtained from 230 customers that answered the two questionnaires.

Findings

The findings suggest that stress indirectly influences customer promoter scoring through satisfaction, while disconfirmation of expectations influences it directly and indirectly.

Practical implications

These results also suggest that stress and disconfirmation of expectations about crowding and accessibility are important in determining promoter scoring. To reduce stress and increase satisfaction and promoter scoring, managers should focus on exceeding customers' expectations about mall accessibility and on ensuring that customers experience a lower level of crowding than they expected.

Originality/value

The article examines Net Promoter Scoring, an outcome that has attracted managers' attention but little is known about its antecedents. The paper provides evidence of the effect of disconfirmation of expectations and negative emotions on promoter scoring.

Abstract

Purpose

The purpose of the study is to determine the prevalence of stress and to identify the occupational stressors among Lebanese police officers.

Design/methodology/approach

Operational Police Stress Questionnaire (PSQ-op) was addressed to 100 randomly selected male Lebanese Police officers. Twenty items from the PSQ-op were run through the principal component analysis to determine the most significant factors of stress and loading within each of the factors.

Findings

The results indicated that 59% of officers reported moderate stress level and 41% reported strenuous stress. Principal component analysis identified six independent factors or stress among Lebanese police officers explaining in total 72.1% of the total variance: excessive workload (30.6%), social-life time management (12.8%), occupational fitness (9.1%), success-related stress (8.6%), physical and psychological health (5.8%), and working alone at night (5.2%).

Research limitations/implications

This research approach encountered some limitations so further research must: use a larger sample size, include female gender and identify other sources of stressors mainly organizational or job context stressors.

Originality/value

Addressing and understanding stress factors among Lebanese police officers helps improving awareness and developing individualized treatment strategies leading police officers to engage in stress-management training to learn coping strategies and use effective tools for preventing stress before it becomes chronic.
