The project manager's role and influence on the project's overall outcome have fascinated many academicians, researchers, and practitioners. The project manager's leadership and human skills play a vital role in the project's outcome;therefore, it is imperative for these competencies to be identified, learned, and leadership styles to be adopted. This study aims to define the most relevant competencies to multidimensional project success and their interrelationship. The quantitative method was used by applying a survey to project managers and team members working in the public sector of Pakistan. The results suggest that a combination of emotional, managerial intelligence, and transformational leadership are stronger predictors of multidimensional public project success. This study has shown that management and leadership need to be integrated to achieve better results. Project managers need to combine soft and hard skills, leadership competencies, and management to engage with people and be effective in terms of processes, tasks, and objectives. © 1973-2011 IEEE.

Recently, the platform economy allows enterprises to collaborate with business partners and provide additional channels for various parties. E-commerce platforms have become integral channels for connecting suppliers with consumers. In the platform economy, agency selling and reselling are two predominant sales models that often coexist for the same product types, resulting in a competitive relationship. This study analyzes transaction data for 30,000 Stock Keeping Units (SKUs) provided by the Chinese e-commerce platforms over one month. We employ three models to compare the sales quantity and profits of manufacturers and online platforms and to identify the most efficient mode for stakeholders based on the model establishment and empirical evidence. Our findings suggest that apart from the existing channel to provide products to customers, manufacturers enter the platform which will increase the profit of platform operators. On the other hand, platform operators may also affect the profit of the manufacturers. © 2023 IEEE.

With the development of society, network security becomes more and more important. It is inevitable to establish the risk index system to effectively monitor the security of network. In the previous study, due to absence of risk indicators, the risk supervising system is not perfect. However, there are few researches on the whole-link risk index system, and the determination of risk indicators lacks basis. Therefore, this paper firstly constructs a new risk index system of situational awareness, which can avoid the omission of risk indicators. Then the sliding window is used to observe this system and the optimal window width is found to determine the dynamic risk pool. Finally, the indicators of dynamic risk pool are used to dynamically monitor the whole link risk index system. The whole technical framework not only proves advantages of the mature risk index system of situational awareness, but also overcomes the disadvantage that the risk index of the whole link cannot be determined, and the dynamic risk pool has the sharing characteristics in the whole process. © 2022 ACM.

Steam ejector plays a key role in the refrigeration system. The water has been used as a working fluid because water is more economical and non-toxic. The operating fluid often enters the evaporator as a water liquid and droplets evaporate by absorbing heat. Cooling load changing causes the vapor in the outlet of the evaporator to be accompanied by droplets. Therefore, there are droplets at the inlet of secondary nozzle and flow should be simulated as a wet steam flow with injection droplets at the secondary flow. In this paper, the effects of droplets injection at secondary flow have been investigated on the performance of the refrigeration cycle. For this purpose, the Eulerian-Eulerian method has been used and the results have been validated with experimental data. Six cases are considered with different wetness and number of droplets in the secondary flow. The results of case 6 show COP, T-outlet, and ER decrease about 22.93%, 15.66%, and 22.93%, respectively. In addition, the steam accompanies by droplets at the outlet of ejector. Therefore, it is essential for designers and operators to model and consider the effects of the droplets on the wall erosion to optimize the wet steam ejector and refrigeration cycle performance.

Evolutionary game analysis of coal industry chain supply chain risk prevention and control from the perspective of resilience

Sustainable Futures 2025年 9卷

Promoting transformation of energy structure while preventing industry chain supply chain risks has become an important issue facing coal industry chain supply chain (CICSC) under “carbon peaking and carbon neutrality”. This study is based on evolutionary game model to investigate the risk prevention and regulatory issues involving chain master enterprises, other enterprises, and government regulators. Research results indicate that: (1) System evolution of risk prevention and control of CICSC is not constant convergence in theoretical optimal strategy combination, there is a systematic bias in behavioral decision-making. (2) Reference effect, risk preferences and other subjective preferences heterogeneity affects value judgment of decision makers. The effect of cost reference is greater than that of utility reference, maintaining risk avoidance in cost problems and risk pursuit in revenue problems can help to improve the quality of individual decision-making. (3) There is a non-linear effect of fairness preference on risk prevention and control of CICSC, it makes fairness preference have the positive impact to risk prevention and control when intensity of fairness preference is in moderate range and types of fairness preference are arranged and combined in a scientific order, otherwise, fairness preference will become a kind of behavior that is “detrimental to others and not beneficial to oneself”. We propose new insights for risk prevention and control from the aspects of achievement transformation and guarantee mechanisms, building reward and punishment mechanisms and so on, call for further analysis of risk prevention and control according to specific risks in each link of CICSC in future research. © 2025 The Author(s)

The role of green HRM in driving a firm's green competitive advantage: the mediating role of green organizational identity

引用

SN Business and Economics 2021年第11期1卷 1-19页

作者： Muisyo, Paul Kivinda Qin, Su Ho, Thu Hau School of Management Xi’an Jiaotong University Xi’an China State Key Laboratory for Manufacturing Systems Engineering Xi’an China The Key Laboratory of the Ministry of Education for Process Control and Efficiency Engineering Xi’an China School of Management Northwest University Xi’an China

Despite the significant contribution made by green human resource management (GHRM) towards the firm's green performance, scholars have not given adequate attention to how GHRM contributes to the green competitiveness of a firm. This situation, therefore, presents a major gap for scholars in green management to fill. We draw on the Ability Motivation Opportunity theory to examine how GHRM drives GCA in a firm. Grounded on this theory, we develop a hypothetical model that is tested by survey data collected from the Chinese manufacturing sector. The results reveal that firms can capitalize on GHRM to build a green competitive advantage (GCA). The findings further illuminate the necessary conditions of green organizational identity (GOI) and green leadership (GL). We believe that the utility and originality of this paper provides a nuanced understanding of how firms can derive GCA from GHRM. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2021.
