Abstract ：
Project governance (PG) has been primarily acknowledged as critical by researchers and practitioners in regard to successfully executing projects. However, project governance of public projects has received less attention from researchers. Therefore, in this study, we studied the effects of project governance and top management support (TMS) on project performance (PP) and their interactions in public sector projects. Using the lens of resource dependence theory (RDT), we hypothesize whether TMS moderates the impact of PG on PP. A quantitative deductive approach was employed to examine this relationship. Quantitative data were collected using a structured questionnaire from 346 project managers, team members, and stakeholders. Our results indicated that PG and TMS are positively significantly correlated with project performance. Moreover, we found that TMS acts as a quasi-moderator in the relationship between PG and PP.

Abstract ：
Recently, information networks are becoming a significant part of daily life, so keeping the system's security is necessary for security tools, such as firewalls and encryption. However, because of the weaknesses of the existing tools, the Intrusion Detection System (IDS) has been implemented to solve the problem. In the application of IDS, feature classification and data analysis are the two most important steps. In this paper, by using the Logit regression model, we attempt to search for the optimal cutting value based on the relationship between cutting value and accuracy index and put forward an input-output port crossed (IOPC) classification for IDS to distinguish the new intrusion features. First, we discuss whole features and propose a taxonomy of IOPC classification for CIC-IDS2017 that is different from other former studies, which can reduce the data space. Second, we compute the distribution curve of cutting values varied with the accuracy index, the purpose of which is to search for the optimal cutting values. Finally, utilizing IOPC classification, the difference between the distribution of the cutting values under the attacks of distributed denial of service (DDoS) and PortScan in CIC-IDS2017 is discussed, which highlights the characteristic that cutting values besieged the attack by PortScan has a conditional distribution compared with DDoS.

Abstract ：
The special geographical locations and socioeconomic functions of seaports and dry ports in the global trading system render them vulnerable to diversified risks. Targeted preventive and adaptive investments can reduce the probability and potential damage of corresponding risks. This study proposes a two-period game to explore the scale and timing of prevention and adaptation by seaport and dry port authorities regarding regular and disruption risks in a competitive environment under ambiguity and asymmetric risk behaviors. The results show that risk aversion increases prevention and adaptation while risk probability ambiguity aversion decreases prevention and adaptation under the effect of information accumulation. Under risk aversion, early prevention and late adaptation are best for port authorities, whereas waiting until the next period to invest is a better option in regard to ambiguity aversion as long as the ambiguity of risk probability can be reduced through information accumulation. Moreover, we extend the risk sensitivity and probability ambiguity models to seaports and dry ports that cooperate and exhibit a leader-follower relationship. Our analysis shows that the cooperative relationship leads to the free-rider effect among port authorities, while the leader-follower relationship enables the seaport and dry port authorities to achieve a Nash equilibrium when choosing early prevention or late adaptation. The findings offer significant economic and managerial insights for the decision-making and policymaking of ports and government authorities.

Abstract ：
The popularity of online shopping places higher demands for e-tailers' service, especially the return process. Cooperative-return-to-store (CRS), where an e-tailer's merchandise can be returned to another retailer's stores, seems to provide a panacea for e-tailers to improve return flexibility and save on return handling costs. However, current practices indicate that only a limited number of e-tailers offer an in-store return option through CRS. This article elucidates the intuition behind this phenomenon by analyzing two asymmetric competing e-tailers' decisions on whether to participate in CRS with a third-party offline retailer who establishes a drop-off convenience level. Perhaps counterintuitively, we find that CRS's return service improvement and cost reduction for e-tailers can deter them from participating in the cooperation under certain conditions. Our analysis also demonstrates that the offline retailer could improve performance by strategically adjusting the CRS program's main appeal (e.g., return service improvement or cost reduction) to the e-tailers based on their product differentiation.

Abstract ：
Prior scholarships have documented that green human resource management practices have performance enabling effects on a firm's green performance. However, there is a dearth of studies that empirically model the extent to which green innovation culture moderates the relationship between green human resource practices and the firm's green performance. To address this gap, this paper established two-fold objectives. First, to examine the effects of green human resource practices and green innovation culture on firm green performance. Second, to model the extent to which green innovation culture moderates the relationship between green human resource management and manufacturing firms’ green performance in China. This was done using data obtained from an extensive scale survey of 300 employees in Chinese manufacturing firms located in the Jiangsu Province. The study suggests that green human resource management practices which include recruitment and selection, training and development, performance management and appraisal, reward and payment, and employee involvement and leadership have a significant effect on green or environmental performance. The study also suggests that green innovation which includes green product innovation culture and green process innovation culture enhances firm green performance. Our paper further suggests that firms that integrate green human resource management practices and green innovation culture are associated with higher green performance than firms that practice green human resource management only. © 2020 Elsevier Ltd

Abstract ：
In order to decrease environment pollution and the usage of raw material, some governments use subsidy policy to encourage the Original Equipment Manufacturer (OEM) and the Independent Remanufacturer (IR) to remanufacture. While, how government subsidy affects remanufacturing activity and industry competition is still unclear. In our research, there are an OEM and an IR in the market. And the OEM and the IR have three different choices of remanufacturing: no-remanufacturing, remanufacturing part, and remanufacturing all. This research builds a game-theoretic model to discuss the impact of government subsidy on manufacturing and remanufacturing quantities, consumer surplus, OEM and IR profit, social surplus and environment for each choice of the OEM and the IR. The result shows that the amount of the OEM remanufacturing decreases with government subsidy when the OEM remanufactures all but the IR remanufactures part. OEM and IR profit, and consumer surplus may decrease with government subsidy in some competitive markets. Total social surplus may also decrease in government subsidy when OEM-IR competition exists in a remanufactured market or only the IR remanufactures part. The change of the total environment impact depends on the relative environment impact of unit manufactured and remanufactured product when OEM or IR remanufactures part. Thus, it is not always a great strategy for policy makers to only increase government subsidy in order to decrease environment pollution and improve social surplus. Before increasing government subsidy, policy makers need to more learn about the competitive markets and environment impact per unit product. Finally, numerical study is conducted to confirm these findings, discuss what happens when the willingness-to-pay of consumers for remanufactured products changes, and analyze the impact of different levels of environment impact per remanufactured product on total environment.

Abstract ：
As seaborne and inland transport hubs, seaports and dry ports are vulnerable to diversified risks, such as climate-change-related disasters and congestion in daily operations, owing to their special geographical locations and socioeconomic functions in seaborne supply chains. If appropriate investments are made before the risks occur, the probability and potential damage of such risks can be mitigated. We propose a two-stage game to simultaneously study the preventive and adaptive investments of seaport and dry port authorities on diversified risks in scenarios of vertical cooperation and horizontal competition. In addition, in the latter case, the asymmetry between seaports and dry ports, regarding their vulnerability to risks, is taken into account. Findings show that it is not always advisable to pursue close cooperation, as players in a horizontal relationship must consider not only their own vulnerabilities but also those of others when making investment decisions. Finally, we find that port authorities need to pay more attention to the free-riding problem in the process of preventive investments than in adaptive investments.

Abstract ：
This research builds two-period game models to address the choice issues of the Original Equipment Manufacturer (OEM)'s licensing strategy and the Independent Remanufacturer (IR)'s distribution channel, considering consumer online reviews in a closed-loop supply chain. In both periods, the OEM sells new products by the direct distribution channel. In period 2, the OEM determines the licensing strategy (the fixed or royalty fee) to authourize the IR to remanufacture, and then the IR chooses the distribution channel (direct or indirect) for remanufactured products. Interestingly, our results show that the IR prefers the direct channel when the remanufacturing cost is smaller. And the obtained willingness-to-pay (WTP) from consumer online reviews has a positive impact on the threshold value of the remanufacturing cost. Moreover, we find that the OEM's licensing strategy choice depends on the sizes of the fixed licensing fee and the obtained WTP. The OEM will choose the royalty licensing strategy to the IR who has chosen the direct channel, when the fixed fee and the obtained WTP are smaller. Finally, we find the optimal royalty fee, numerically examine the impact of the interaction among these factors on consumer surplus and social welfare, and relax the basic assumption to show the robustness of our model.

Abstract ：
Purpose The purpose of this research is to examine how firms can build collective organisational citizenship behaviour towards the environment (OCBE) from green human resource management (GHRM) practices. The study tests how the three main aspects of GHRM, namely green abilities, green motivation and green opportunities, give rise to the enablers of green culture (EGC). The study further tests how each of the EGC (leadership emphasis, message credibility, peer involvement and employee empowerment) leads to the development of OCBE at the organisational level of analysis. Design/methodology/approach Data were collected from Taiwanese manufacturing companies with a target of departmental heads. The authors managed to get 284 valid responses and analysed the data using path analysis on Stata12. Findings The study findings suggest that GHRM practices that include developing green abilities, green motivation and green opportunities support the development of the EGC. The EGC include leadership emphasis, message credibility, peer involvement and employee empowerment. It was, however, found that green abilities do not support the development of message credibility. It was further found the EGC lead to the development of collective OCBE except for peer involvement. Originality/value The authors propose an original concept of EGC in the context of Taiwanese manufacturing firms. This paper is amongst the pioneer papers to test the OCBE at organisational level. The authors also develop an integrated conceptual framework upon which firms can use in order to build OCBE at organisational level. Previous studies have examined OCBEs at employee/individual level.

Abstract ：
Wind generation fluctuation results in the electricity supply uncertainty of the company in electricity market. And this uncertainty has an important impact on hourly electricity price. In our paper, we use game models to optimize hourly price for different risk appetites’ companies considering the uncertainty. For the risk-neutral company, we solve the optimal electricity price by maximizing the expected profit. For the risk-averse or risk-preferring company, we consider wind electricity generation as a Weibull distribution and obtain the optimal electricity price based on conditional value at risk. In numerical examples, we find that the risk-preferring company sets the highest electricity price, demonstrating the importance of modeling risk appetites of the company in electricity price. And the results indicate that a risk-averse (risk-preferring) company will set a higher (lower) electricity price for a larger risk confidence level. Besides, we find that the company will lower electricity price with the decrement of users’ price elasticity. Furthermore, our finding shows that the profit of the company increases with the wind penetration due to the decreased cost, which supports the observed and investigated results in electricity market. © 2021 Taylor & Francis Group, LLC.
