The results of a study to characterize episodes of driver fatigue and drowsiness and to assess the impact of driver fatigue on driving performance are documented. This data-mining effort performed additional analyses on data collected in an earlier study by the Federal Motor Carrier Safety Administration of the effects of fatigue on drivers in local and short-haul operations. The primary objectives of the study were to investigate fatigue as a naturally occurring phenomenon by identifying and characterizing episodes of drowsiness during all periods of driving and to determine the operational or driving environment factors associated with drowsy driving. A total of 2,745 drowsy events were identified in approximately 900 total hours of naturalistic driving video data. Higher levels of fatigue were associated with younger and less experienced drivers. In addition, a strong and consistent relationship was found between drowsiness and time of day. Drowsiness was twice as likely to occur between 6:00 a.m. and 9:00 a.m., and approximately 30% of all observed incidences of drowsiness occurred within the first hour of the work shift. Insights about the relationship between driver fatigue and driver distraction and inattention are provided. This study presents an analytical framework for quantitatively assessing driver fatigue and drowsiness as a function of driver characteristics and the driving environment. It is hoped that the results will help to identify effective countermeasures for drowsy driving that will reduce the number of commercial-vehicle-related fatalities and injuries.

Critical Aspects

Undergraduate students completed an online tutorial to investigate the impact of the method of presentation on performance, the relationship between personality characteristics and performance, and where and when students complete the tutorial. Performance on the posttest was not significantly different whether students reviewed the animated video or recorded PowerPoint presentation, but performance improved in both conditions from the pretest scores. Contrary to expectation, personality was not related to performance on the posttest. Students generally completed the tutorial in a private space such as a bedroom or dorm room and there was no specific time of day when students were more likely to complete the tutorial. These data suggest that the method of presenting the tutorial might be less important than the use of elaborative inquiry to focus the students’ attention onto critical aspects of the material and to have students think critically about the subject matter. In addition, it is possible that the use of elaborative inquiry might reduce the relationship between personality and success in online learning.

The State of Qatar has implemented several family policies in order to improve the wellbeing of Qatari families and ensure fair distribution of development benefits for both men and women. However, there is a linkage between female employment outside the home and instability in the marriages of Qatari families. This paper investigates the impact of female employment on marital stability, based on the results of primary data collected in Qatar, a questionnaire that consisted of several sections such as challenges in the workplace, supervisor, family and spouse relations, work motivation and performance. Of the 824 questionnaires that were returned, 807 were completed and valid for analysis. Regression analysis and an ANOVA test have been used to test the relationship between the variables. The results of the research have produced mixed findings about how wives’ employment increases marital instability and have yielded few significant differences on mean scores of discuss on work demands, insufficient time together, housework, financial matters, communication, relatives and rearing children. The results indicates that in general Qatar working women face several challenges in relation to their marital life as part of cultural and social constraints.

Background Considering the importance of entrepreneurship and the impact of burnout on workers’ health, this study aims to explore the presence of burnout in entrepreneurs and the interaction of hardy personality (HP) in this process. Method The sample included 255 Spanish entrepreneurs. Occupational factors, working hours, labour immersion, HP, burnout syndrome (i.e. Emotional exhaustion, Depersonalization and Lack of accomplishment) and burnout consequences were assessed. Results Descriptive analysis showed that entrepreneurs had low levels of occupational factors, burnout syndrome and consequences. Hierarchical regression exploratory results indicated that working hours, labour immersion, and Emotional exhaustion were the most relevant predictors of the consequences. Besides, mediation models with PROCESS macro (v.3.0) highlighted the indirect effect of occupational factors and showed that emotional exhaustion was the only component of burnout that mediated in between the predictors and the consequences. As well, HP moderated the relationship between occupational factors and emotional exhaustion. Conclusions Occupational factors are the main predictor of burnout in entrepreneurs and HP could prevent their effect on Emotional exhaustion. The results suggest the importance of training to promote HP for better health and performance of entrepreneurs.

Purpose This study aims at providing empirical evidence pertaining to the interaction among authentic leadership, workplace harmony, worker's creativity and performance in the context of telecommunication sector. These research streams remain important issues and of interest as the world continues to migrate toward a knowledge-based economy. Design/methodology/approach Applying structural equation modeling, this study diagnosed the impact of Authentic leadership (AL) on employees (n = 345) in two Jordanian telecommunication firms, specifically, how it shapes workplace climate, creativity and job performance. The study also tests the moderating role of knowledge sharing in the model, as well as the mediating role of workplace climate on the relationship between AL and positive organizational outcomes. Findings The empirical result suggests that AL positively influences workplace climate, creativity and job performance; workplace climate positively influences creativity and job performance; workplace climate mediates the relationship between AL and creativity, and job performance; and knowledge sharing behavior moderates the relationship between AL and workplace climate. Originality/value This study highlights the magnificent power of AL and knowledge sharing, not only in shaping the workplace atmosphere but also in delineating how these variables stimulate creativity and performance among employees. The implications for research and practice are discussed.

Purpose – The purpose of this paper is to analyze the relationship between financial disclosure and the financial performance of microfinance institutions (MFIs). Design/methodology/approach – The paper utilizes ordinary least squares method to analyze the impact of disclosure on financial performance, an ordered probit model to investigate the possible effect of financial performance on disclosure and utilizes a three-stage least squares method to delineate the endogenous relationship between disclosure and financial performance of MFIs. Findings – The paper finds that better disclosure has a statistically significant positive impact on operational performance of MFIs; second, it also shows that improved financial performance results in better financial disclosure. Keeping the endogenous nature of the relationship between disclosure and performance, the paper uses a three-stage least squares method to show that disclosure and financial performance positively affect each other simultaneously. Research limitations/implications – The paper attempts to delineate a positive association between better disclosure on financial performance of MFIs, which can be used for developing a better disclosure policy by management, formulating more effective guidelines for disclosure by the stakeholders and mandating more appropriate laws and uniform disclosure practice by regulators. Originality/value – This is the first study that uses a large number of MFIs from 75 countries; second, it uses a uniform scale of designating a disclosure rating (assigned by MIX Market) to show the relationship between disclosure and performance. Finally, it uses three-stage least squares method to address the possible endogeneity between disclosure and performance.

Entrepreneurial passion is seen as a valuable predictor of entrepreneurs' behavior and performance. We explored what makes entrepreneurs passionate by adopting a qualitative research method from a social support perspective. To test our hypotheses we conducted a survey with 287 young entrepreneurs in China. Using structural equation modeling we studied the impact of three types of support from the family on entrepreneurial passion. The results show that financial support and social capital support had a stronger influence on entrepreneurial passion than did emotional support. Further, psychological capital played a partial mediating role in the relationship between family support and entrepreneurial passion. This study enhances the integrity of previous research conclusions on entrepreneurial passion and, in particular, provides further insight into the development of nascent entrepreneurs and their new businesses.

Purpose The incompatibility between the sphere of work and the family is a reality that plagues many workers today. The difficult articulation of these two domains leads to the experience of the phenomenon called work–family conflict (WFC). This paper aims to assess the impact that WFC may have on employee engagement and performance, as well as on their turnover intention. It is also intended to test the mediating effect of engagement on the relationship between WFC and performance, and between WFC and the turnover intention. Design/methodology/approach One hundred and sixty-seven employees from various Portuguese organizations were surveyed. Respondents reported their perceptions of own WFC, engagement, performance and turnover intention. Findings The results revealed that employees who feel a higher WFC have lower levels of engagement and greater intention to leave the organization. The WFC showed no relation to performance. Engagement takes on the mediating role in the relationship between WFC and the turnover intention. Practical implications The relevance of this study is related to the implications that it may bring to companies in the context of implementing work–family balance strategies to reduce the referred conflict. Originality/value This study contributes to WFC literature by attempting to integrate in the same model four concepts in a single study to provide a model that depicts the chain of effects between WFC, engagement, individual performance and turnover intention, which has never been done in the Portuguese context.

Previous studies considered entrepreneurial orientation as a determinant of firms’ growth and performance. In this research, we are interested in spin-offs. Indeed, we aim to study the relationship between their entrepreneurial orientation and their performance. Therefore, we carried out a cross-cultural study in three different countries; Tunisia, Canada, and Morocco. We opted for a personal survey. We addressed our questionnaire to 180 managers of spin-offs and we analyzed the research variables using SPSS 20.00 (Statistical Packages for Social Sciences) and Smart PLS 3 (Partial Least Squares). Our findings highlight a positive correlation between entrepreneurial orientation and performance of spin-offs within the three samples.
