The Internet of Things (IoT) is used in the fresh agricultural product (FAP) supply chain, which can be coordinated through a revenue-sharing contract. The purpose of this paper is to make the three-level supply chain coordinate in IoT by considering the influence of FAP on market demand and costs of controlling freshness on the road.

A three-level FAP supply chain that comprises a manufacturer, distributor, and retailer in IoT is regarded as the research object. This study improves the revenue-sharing contract, determines the optimal solution when the supply chain achieves maximum profit in three types of decision-making situations, and develops the profit distribution model based on the improved revenue-sharing contract to coordinate the supply chain.

The improved revenue-sharing contract can coordinate the FAP supply chain that comprises a manufacturer, distributor, and retailer in IoT, as well as benefit all enterprises in the supply chain.

Resource utilization rate can be improved after coordinating the entire supply chain. Moreover, loss in the circulation process is reduced, and the circulation efficiency of FAPs is improved because of the application of IoT. The validity of the model is verified through a case analysis.

This study is different from other research in terms of the combination of supply chain coordination, FAPs, and radio frequency identification application in IoT.

The purpose of this paper is to examine how signals of uncertainty in the media affect retail investor decisions and initial public offering (IPO) underpricing through theoretical and empirical methods.

The authors construct a theoretical model of the influence of media signals on IPO pricing, which describes the micro process in which uncertain signals in media influence retail investors’ decisions and IPO underpricing. Besides, the authors take 516 small and medium-size enterprises (SMEs) listed in A-share from July 2009 to December 2012 as samples for empirical tests and establish an in-depth learning model for text analysis with Java programming to measure Chinese media tone. Finally, the results of the model analysis are verified by empirical results.

The results show that authoritative media with high credibility can reduce the uncertainty of information sources attract more investors’ attention and improve the valuation and demand of retail investors. The higher the media credibility is the higher the IPO underpricing rate is. The uncertain tone of the media will increase the decision-making cost of investors reduce the valuation expectation and demand of the secondary market and lead to a lower IPO underpricing rate.

The authors study the influence of the uncertainty of media source and media content on the degree of IPO underpricing of SMEs. This is a useful supplement to the Chinese media tone research system that is still in the exploration stage. The research has reference value for government regulation and investor decision-making.

The problem of stress is increasingly gaining attention in the construction industry in recent years. This study is aimed at examining the causes, effects and possible alleviation of stress of project management (PM) practitioners so that their stress could be appropriately managed and reduced, which would contribute to improved mental health.

Primary data were collected in an online questionnaire survey via Qualtrics. Questions ranged from PM practitioners’ stressors, stress and performance under stress to stress alleviation tools and techniques. One hundred and five PM practitioners completed the questionnaire. Their responses were compiled and analyzed using descriptive statistics, correlation and regression.

The results confirmed that the identified stressors tended to increase stress of PM practitioners. All stressors tested in this study were found to have negative impact on the performance of PM practitioners. In particular, the burnout stressors were seen as the key stressors that influence the performance of PM practitioners and have a strong correlation with all the other stressors. It was also found that a number of tools and techniques can reduce the impact of stressors on PM practitioners.

This study has taken a specific focus on stress-related issues of PM practitioners in the construction industry due to their critical role in this project-dominated industry. Using the Job Demand-Resource theory, a holistic examination was not only conducted on stress and stressors but also on alleviation tools and techniques. This study has thus made significant contribution to the ongoing research aimed at finding solutions to mental health-related problems in the project-dominated construction industry, thereby achieving the United Nations’ social sustainability development goals.

Proactive career behavior (PCB) is an effective form of career self-management that has positive impacts on individual career development and career success, and therefore, the purpose of this paper is to explore the driving factors of PCB.

Drawing on the interactionist perspective and situational strength theory, this study examined the independent and joint effects of role commitment and pay-for-performance (PFP) on employees' PCB based on data collected from 298 Chinese private enterprise employees at two time points.

The authors found that occupational role commitment (ORC), parental role commitment (PRC) and PFP were positively related to PCB. Furthermore, PFP moderated the relationship between ORC/PRC and PCB, such that the two relationships were stronger when PFP was low.

Drawing on the interactionist perspective, the authors contribute to the literature on PCB by revealing novel antecedents of PCB: ORC, PRC and PFP. The authors also contribute to the situational strength theory by examining how role commitment and PFP may interact to impact employees' PCB. Finally, the authors are among the first to consider the effects of role commitment on individual career behaviors, thus extending the nomological network of role commitment.

Architectural, engineering and construction (AEC) project organizations are under constant pressure to improve the mental health of project management practitioners (PMPs) due to complexity and dynamism involved in project management practices. Drawing on institutional theory, this research explores how external environmental factors, political factors, economic factors, social factors, technological factors, environmental factors and legal factors (PESTEL), influence mental health management indicators that contribute to positive mental health.

Purposive sampling method was used to collect survey data from 82 PMPs in 60 AEC firms in Australia. Structural equation modelling was used to test the hypotheses based on 82 items of data collected from PMPs.

Overall, this study revealed interesting findings on the impact of external environmental factors on mental health. The hypothesized positive association between political factors and mental health management indicators was rejected. The data supported the proposed hypothetical correlation between economic factors and mental health management indicators and the influence of social factors on mental health management indicators. Moreover, a hypothetical relationship between technological factors and mental health management indicators was supported. The significant positive impact of environmental factors on mental health management indicators proposed was supported, and legal factors’ positive correlation on mental health management indicators was also supported.

Despite the limitations, the present findings suggest that all the external environment factors except political factors shape mental health management outcomes.

The lack of studies about the relevance of disaster awareness factors and disaster evacuation as a part of disaster responses especially for fire cases in an academic environment in Indonesia has triggered this study to explore the disaster awareness factors and evacuation experiment without emergency alarm for case study students in the classroom. The relevance of disaster awareness factors in transforming into practical action and decision in a disaster evacuation need to be examined to study the relevance of both phases in disaster.

This research conducted a quantitative approach by studying questionnaires from 162 respondents collectively divided into five groups to examine the student disaster awareness factors randomly from those groups. The qualitative approach was implemented through the evacuation experiments that were conducted twice to analyze the disaster evacuation performance. The analysis for the relevance is conducted by comparing the result of the questionnaire study and the evacuation experiment.

According to the questionnaire study, generally, the students are highly confident with their hazard knowledge in disaster awareness except that half of them are doubtful about appropriate steps in a disaster. The experiment without explosive sound showed that they have slower responses in the critical moment of evacuation. The response in the experiments showed relevance with several disaster awareness factors

This study has explored the relevance of disaster awareness factors with disaster response in a campus building. In the part of reducing risk during fire disaster, this research shows the importance of social interaction and hazard knowledge during the disaster.

The improvement of disaster evacuation procedures and training in a campus building is mandatory to reduce disaster risk based on the relevance of disaster awareness factors and disaster response in this study.

This study measures the relevance of disaster awareness factors performance of the students by comparing it to their actions and decisions in an experimental setting of fire building. The disaster awareness factor performance was measured by a questionnaire survey while the experiments were deployed to observe the performance of their actions and decisions during evacuation as part of the disaster response phase.
