The consideration of the substitution phenomenon in the project portfolio selection problem can improve the robustness of project portfolio selection and help enterprises better achieve their strategic objectives. However, the existence of inter-project risk propagation will have a negative impact on project substitution. This paper proposes a new framework for project portfolio selection and constructs a risk propagation model based on strategic objectives to study the impact of risk propagation on substitution in the project portfolio.

The authors first construct a risk propagation model based on strategic objectives to describe the risk propagation between projects. Then the project substitution phenomenon based on risk propagation is put forward, and the calculation method of substitution loss is given. Finally, a robust project portfolio selection framework based on strategic objectives considering risk propagation is constructed.

The analysis of a case study demonstrates that (1) With the increase of risk intensity, the strategic loss of the same project portfolio increases linearly, and under the same risk intensity, the more projects in the portfolio, the stronger the robustness. (2) Considering risk propagation, the effect of project substitution is significantly weakened, and the strategic loss rate of the project portfolio is significantly increased compared with that of a direct attack.

This study is the first to take the project substitution into account in the project portfolio selection process. Moreover, the authors describe inter-project risk propagation and analyze the impact of risk propagation on the project substitution phenomenon. Finally, the authors extend the evaluation index of robustness. This paper puts forward a new way to solve the problem of project portfolio selection.

University academicians are struggling to engage in teaching, supervision, research and publication. The purpose of this paper is to determine how academicians cope with the various burdens of academia work stressors to overcome burnout.

A cross-sectional study was conducted from January to July 2017. In total, 327 research university academicians were selected using a proportional stratified randomized sampling. Validated measures were used to collect data on perceived work stressors (teaching, research, interpersonal conflicts and career development), coping strategies (adaptive and maladaptive coping) and perceived burnout (emotional exhaustion (EE), depersonalization and personal accomplishment (PA)). The data were gathered via computer assisted self-interviewing (CASI). The research statistical model was tested by two-steps of assessment replicating covariance-based structural equation modeling (CB-SEM) with bootstrapping procedure to generalize the sample to the hypothesized model.

Overall data fit the hypothesized model well (CMIN/df=1.788, GFI=0.833, CFI=0.921, TLI=0.916, RMSEA=0.047) with various degree of explanatory value for EE, depersonalization and PA were 60, 49 and 22 percent, respectively. Academicians were resilient against the burden of teaching. However, they did adopt coping mechanisms to overcome research challenges and interpersonal conflicts. The effects of research and interpersonal conflicts on tri-dimensional burnout mediated by maladaptive coping (f² effect size=0.37) had a larger effect than interpersonal conflicts toward burnout mediated by adaptive coping (f² effect size=0.02).

Academicians adopt maladaptive coping for research and interpersonal conflicts to suppress burnout. An integrative approach at both organization and individual levels is crucial to enhance appropriate coping mechanism to curb with burnout among the academicians of a research university.

This is the first study in Malaysia which uniquely estimate the effects of academician’s work stressors toward burnout with introducing coping strategies as mediators toward work stressors and burnout relationship which has been analyzed via CB-SEM.

The study aims to determine the impact of non-Muslim tourists’ perception of halal tourism products and services (PHTPS) on trip quality, trip value, satisfaction and word of mouth (WOM) towards halal tourism destination.

A total of 375 non-Muslim tourists were surveyed in Malaysia using partial least square technique.

The findings showed that PHTPS has a significant impact on all four dimensions. The strongest relationship was found between PHTPS and trip quality, followed by PHTPS–WOM, PHTPS–satisfaction and PHTPS–trip value.

This study provides new insights into the theory and practice of non-Muslim tourists’ PHTPS and WOM towards halal tourism destination. The findings are valuable to tourism operators, managers and marketers with the understanding and responsibility to develop halal tourism products and services from non-Muslim tourists’ insights.
