This study aims to theoretically construct the role of hospitality job characteristics (HJCs), conceptually identify specific HJCs and empirically examine the relationships of these to work–family conflict and job stress. Hospitality employees work in a “smile factory” – often under stress.

Data were collected from 346 hotel employees in China and analyzed using structural equation modeling (SEM) and a series of hierarchical regression analyses (HRA).

The SEM results confirmed the general role of HJCs as a job stressor, and the HRA findings differentiated the specific impacts of the characteristics on work–family conflict and job stress.

The survey was cross-sectional and correlational in nature. Furthermore, the results were also from selected hotels, and the respondents do not fully represent all hotel employees. Finally, the measures of hospitality job uniqueness were employees’ subjective agreement on the given statements.

The study offers a systematic framework of specific job characteristics in the hospitality context for the reconciliation of previously inconsistent research findings. The findings may also be useful to hospitality managers as they attempt to analyze and understand the specific job characteristics that are the most salient reasons for withdrawal attitudes and behaviors.

The present study identified the list of HJCs by summarizing previous studies and examining the roles of HJCs in work attitudes among hospitality employees. These efforts could be helpful both for scholars by constructing a consistent base for future research and for managers by precisely analyzing the specific job attributes.

Introduction: The birth of a preterm child requires hospitalization in a neonatal intensive care unit (NICU), which is a very stressful experience for parents. Aim: To determine the stress level of parents of preterm babies admitted to intensive and sub-intensive units in two hospitals in Northern Italy and its association with their sociodemographic variables and the clinical conditions of their newborns.

The sampling was non-probabilistic and included parents of preterm babies admitted to intensive and/or sub-intensive care for at least 10 days. Instruments: (1) information deduced from the clinical record of preterm newborns; (2) sociodemographic determinants of parents' well-being deduced from a questionnaire; (3) parental stress scale: neonatal intensive care unit (PSS:NICU), which measures the perception of parents about stressors from the physical and psychological environment of the NICU.

Results: A total of 104 parents of 59 hospitalized preterm babies participated in the study. The average parental stress level was 1.87 ± 0.837. The subscale score that got higher was parent-infant relationship subscale. Concerning the infant characteristics, the birth weight of the babies and the length of their hospitalization affected the parents' stress level. Looking at parents' sociodemographic characteristics instead, the greater predictors were gender, age and occupational social class.

The parental role alteration caused by infant premature birth and consequent hospitalization is a major stressor for parents and in particular for mothers. The variables that resulted positively associated with higher stress in parents of preterm infants hospitalized are specific parental characteristics, including not adequately or previously studied ones, and infant characteristics.

The purpose of this paper is to identify social and organizational antecedents of stress. This paper also investigates whether attitudes toward organizational changes and reforms might explain stress perception (SP) and mediate the relationships between social and organizational job characteristics and SP.

A quantitative approach is used to identify the relationships between the research variables. The investigated population is composed of middle managers working in Swiss public hospitals (n=720), which are currently being confronted by major reforms.

The findings show that perceived social support (work relationships with and support from colleagues), as well as several job characteristics (autonomy in performing tasks, flexibility in the organization of working time, degree of conflict) are significantly related to SP. Moreover, positive attitudes toward change are negatively related to stress, and mediate the relationships between perceived social support as well as job characteristics and SP.

This paper sheds light on several job characteristics which could contribute to mitigating SP among middle managers. The findings could therefore guide HRM specialists in their efforts to create a favorable work environment so as to facilitate middle managers’ activities.

The innovation of this paper is grounded in the specific population the author investigate, as the empirical inquiry concerns middle managers working in public hospitals. Moreover, this research highlights the central role of job characteristics and attitudes toward change in explaining SP.

The nature of work has changed in the past 30 years but we do not know what these changes have meant for worker job stress. In this chapter we compare data from three surveys of the quality of work life from 1972 to 2002. At the most general level, work today is less stressful than it was in 1972. Workers report fewer job demands, more decision latitude, less job strain, more job security and greater access to job resources and job support. However, these changes have not affected all workers equally. Women, those with less education, non self-employed workers, blue collar workers and workers in manufacturing industries showed the greatest decreases in job stress although levels of job stress remain higher than for comparison groups (men, college educated, white collar, service workers). Changes were not always linear across time suggesting that some aspects of job strain are sensitive to economic cycles.

Construction professionals (CPs) are often exposed to various challenges and pressures at work including urgent deadlines, high demands, uncertainty in tasks, and complex problems, which may induce stress and affect performance directly. Mindfulness-based stress reduction (MBSR) training has been used for several years to reduce stress among various types of people, such as nurses, teachers, and family caregivers, but its application to CPs with highly dynamic environment remains uncertain. This study aimed to investigate the impact of MBSR training on the performance of CPs via an intervention study involving two groups (MBSR and control).

Participants in both groups were assessed using a questionnaire survey and a semi-structured interview at the pre- and post-intervention stage. Multiple research methods were used to derive quantitative and qualitative analyses, including factor analysis, independent t-test, Pearson correlation, and contextual analysis.

The findings overall confirm that MBSR has a direct effect on CPs, improving their mindfulness characteristics and enhancing performance by reducing their stress.

A number of practical recommendations are made such as (1) arranging standard eight-week MBSR training for CPs; (2) giving special leave for attending the full mindfulness training; (3) establishing a suitable environment in the office for meditation;(4) allowing CPs an opportunity to pause at difficult moments to create space to respond instead of simply reacting; and (5) expressing love and kindness through gratitude, recognition, and regular feedback.

This research can be considered as valid evidence to convince construction organizations conducting MBSR to the CPs, which is indeed not too remote to enhance their performance as well as the holistic construction performance.

Crops are increasingly affected by drought; hence, the current study explored the potential role of three desert endophytic fungi, Aspergillus fumigatus, Aspergillus terreus and Talaromyces variabilis, in conferring drought tolerance in tomato plants.

Preserved endophytic fungi from a Rhazya stricta desert plant were adopted to obtain the required fungal treatment; tomatoes received fungal treatments directly in plastic trays and subsequently in pots. Drought was applied using 15% of PEG-6000 at two stages: flowering and fruiting. The following parameters were measured: pollen sterility, growth characteristics, morphological analysis and biochemical analysis, including proline, gibberellic acid (GA3) and chlorophyll measurements; thus, the data were analyzed statistically using SPSS software.

All applied endophytes significantly promoted pollen viability and tomato yield under stressed and nonstressed conditions. Interestingly, these endophytes significantly enhanced the number of trichomes under drought stress and promoted tomato fruit quality. The colonized tomato plants accumulated a high proline level under drought stress but lower than un-inoculated stressed plants. Also, a significant rise in growth characteristics was observed by A. fumigatus and A. terreus under normal conditions. Moreover, both raised GA3 levels under drought-stressed and nonstressed conditions. Also these two endophytes enhanced chlorophyll and carotenoid contents under drought stress. Fruit characteristics were enhanced by nonstressed T. variabilis and stressed A. fumigatus.

The present endophytic fungi provide impressive benefits to their host in normal and drought-stressed conditions. Consequently, they represent valuable sources as sustainable and environmentally friendly alternatives to mitigate drought stress.

This study aims to research the development trend, research status, research results and existing problems of the steel–concrete composite joint of railway long-span hybrid girder cable-stayed bridge.

Based on the investigation and analysis of the development history, structure form, structural parameters, stress characteristics, shear connector stress state, force transmission mechanism, and fatigue performance, aiming at the steel–concrete composite joint of railway long-span hybrid girder cable-stayed bridge, the development trend, research status, research results and existing problems are expounded.

The shear-compression composite joint has become the main form in practice, featuring shortened length and simplified structure. The length of composite joints between 1.5 and 3.0 m has no significant effect on the stress and force transmission laws of the main girder. The reasonable thickness of the bearing plate is 40–70 mm. The calculation theory and simplified calculation formula of the overall bearing capacity, the nonuniformity and distribution laws of the shear connector, the force transferring ratio of steel and concrete components, the fatigue failure mechanism and structural parameters effects are the focus of the research study.

This study puts forward some suggestions and prospects for the structural design and theoretical research of the steel–concrete composite joint of railway long-span hybrid girder cable-stayed bridge.

Coatings are widely used in gears to keep interface from wearing excessively. The purpose of this paper is to study the effect of coating properties and working conditions on the pressure, the shear traction, stresses as well as the fatigue life of spur gear.

A numerical contact fatigue life model of a coated spur gear pair under elastohydrodynamic lubrication (EHL) is developed based on the characteristics of gear geometry and kinematics, lubrication conditions and material properties. Frequency response functions and the discrete convolute and fast Fourier transform (DC-FFT) algorithm are applied to obtain elastic deformation and stress. Mutil-axial fatigue criteria are used to evaluate the contact fatigue life based upon the predicted time-varying stress fields of coated bodies.

The maximum Mises stress decreases while the fatigue life increases as the coating modulus decreases. A thinner coating leads to a longer life and a smaller maximum Mises stress for hard coatings. The load has more significant effect on the contact fatigue life of soft coatings.

The developed model can be used to evaluate the contact fatigue life of coated gear under EHL and help designers analyze the effect of coating elastic modulus and thickness on the contact pressure, film thickness and stress.

A FEATURE of many of the light alloys now in common use is that the stress and strain curve often does not evidence any well defined region in which the elastic strain becomes plastic strain, and a linear portion of the diagram from the origin, which in the case of so many metals represents a region of proportionality, is sometimes almost non‐existent, the diagram being curved right from the origin so that it is not possible to define any region or limit of proportionality, and the proof stress; by standard definition, has accordingly a relatively low value compared with the ultimate tensile stress of the alloy concerned. (Fig. 1).

The overall purpose of this paper is to examine the extent to which breaches in psychological contracts and perceptions of organizational fairness account for variations in job stress experienced by operational police officers (as measured by psychological distress and employee performance), after controlling for the variance associated with more established job stressors (i.e. job demands, job control and social support).

This study is based on data collected through a self‐report survey involving operational members of a large Australian police force (n=582).

Results of hierarchical multiple regression analyses indicate that vast majority of explained variance in psychological distress and extra‐role performance is attributed to the additive effects of demand, control, and support. Furthermore, only one of the social exchange dimensions (interpersonal fairness) is predictive of either target variable.

The limitations that need to be taken into account are the cross‐sectional nature of the study design and the focus on a single police service.

Despite the generally weak support for the social exchange variables, there are signs that dimensions of justice (particularly interpersonal justice) should be included in future police‐stress investigations. The results also suggest that job characteristics such as job demand, job control and social support should be taken into account when developing strategies to prevent and/or reduce chronic job stress in policing services.

This is one of the first studies to examine the relationships between psychological contract breach, perceptions of fairness and police stress.
