Building an assessment model for measuring airport resilience

Airports are some of the most important facilities in any country's transportation system. It is important to protect such critical infrastructure from natural and manmade risks. However, it is difficult to build a risk prediction model based only on past statistical data. An experienced expert-based Multiple Criteria Decision-Making (MCDM) approach could be used to measure an airport's resilience and develop feasible protection strategies. This study proposes a novel assessment model for evaluating airport resilience. The model uses the Bayesian Best Worst Method (Bayesian BWM) to determine the optimal group weights of the criteria, and the modified Preference Ranking Organization Method for Enrichment Evaluations (modified PROMETHEE) technique to calculate the gap between each alternative and the aspiration level. The practicality and effectiveness of the model are demonstrated using Taiwan's airports as an example. In addition, sensitivity analysis and model comparisons are conducted to confirm the reliability of the proposed model. The results show that the proposed assessment system can effectively assist policy makers and airport security departments to formulate improvement strategies, thereby enhancing the resilience of this infrastructure.     

分布式创新参与者动机对行为的影响机制:以开源社区为例

开源社区是分布式创新的典范,开源社区参与者知识创新动机与行为备受关注。以我国330名开源社区参与者为对象,运用结构方程模型研究了参与者动机对行为的影响机制。研究结果表明:学习动机、交流动机、兴趣动机和职业发展动机依次通过有用性感知和参与意向间接激发参与行为;动机对行为影响大小的排序为职业发展动机、兴趣动机、学习动机和交流动机。职业发展动机除间接影响参与行为外,还会直接增进学习动机和交流动机。比较研究模型和竞争模型的拟合结果可知,研究提出的"动机-行为过程"分析框架明显优于传统的"动机-行为"框架。     

Exploring the effect of Starbucks' green marketing on consumers' purchase decisions from consumers’ perspective

This study contributes to current literature by constructing a model to evaluate how using green marketing to promote brand image affects consumers' purchase intentions. First, the decision-making trial and evaluation laboratory (DEMATEL) method was used to explore the mutual influence on evaluation indicators, and an influential network relation map (INRM) of indicators and sub-indicators was constructed based on the results. The DEMATEL method was then combined with the analytic network process to create a DANP method to calculate weights for each indicator and sub-indicator. A modified Vlse Kriterijumska Optimizacija Kompromisno Resenje (VIKOR) method was then employed to explore the comprehensive performance of each indicator and sub-indicator using empirical data. Finally, conclusions were summarised and suggestions were proposed. This study's findings can serve as a reference for firms seeking to improve the tangible effects of their green marketing strategies by stimulating consumers' purchase intentions.     

Discount pricing for a family of items: The supplier's optimal decisions

Consider a family of SKUs for which the supplier will offer a quantity discount, according to the aggregate purchases of the product group. Management of those items is based on the modified periodic policy. From the supplier's point of view, what are the optimal parameters (breakpoint and discount percentage)? For deterministic demand, we discuss the cases in which demand is both constant and price-sensitive. First as a noncooperative Stackelberg game, and then when the two parties make the discount and replenishment decisions jointly, we illustrate the impact of price-sensitivity and joint decision making on the supplier's discount policy.     

Antecedents and Consequences of Consumers' Attitude toward Social Commerce Sites

Drawing upon technology acceptance model (TAM), this study investigates the antecedents and consequences of consumers' attitude toward social commerce sites. In addition to the antecedents of perceived usefulness and perceived ease of use from TAM, the study includes such factors as perceived trust, perceived shopping enjoyment, perceived shopping risk, and perceived social presence. The study results suggest that consumers' attitudes toward social commerce sites are significantly impacted by perceived usefulness, perceived ease of use, perceived shopping enjoyment, and perceived shopping risk. The study also finds that consumers' attitudes toward social commerce sites significantly influence the effects of e-word-of-mouth (eWOM) intention, intention to return, and e-purchase intention. This study provides an integrative approach to evaluating antecedents and consequences of consumers' attitude toward social commerce sites. Limitations and future research are discussed.     

经济增长动力是研发的直接效应还是溢出效应

通过改进的菲德模型,分离出研发的直接效应和溢出效应,分别讨论了研发的总效应、直接效应和溢出效应与经济增长的关系,最终识别出经济增长的动力。理论模型表明：研发的溢出效应促进经济增长,而研发的直接效应与经济增长的关系取决于在要素边际收益上研发部门与生产部门的相对大小;短期内,研发与经济增长的关系不明确,但长期看,研发驱动经济增长,动力来自研发的溢出效应;应用研发始终促进经济增长,而基础研发与经济增长的关系不明确;经济政策不会改变研发的溢出效应,但可以改变研发的直接效应,进而影响经济增长。实证分析表明：中国经济增长的动力来自基础研发的溢出效应和应用研发的直接效应。     

Exploring factors influencing US millennial consumers’ use of tap-and-go payment technology

ABSTRACT

Although mobile payment (MP) represents a possibility for traditional brick-and-mortar US retailers to enhance the quality of customer service, mobile payment adoption in the US has lagged, with research regarding this phenomenon in the US seemingly in its embryonic stage. The current study contributes to the literature on mobile payment adoption in the US by investigating the factors on US millennial consumers’ use of mobile payment technology, operationalized in the study as tap-and-go payment systems. The study mirrors a study of the acceptance of mobile shopping technology among German consumers, with some extension. The study incorporated mobile payment risk perception, system trust, and socio-cultural influence into an extended technology acceptance model (TAM) to explore this issue. Results from a survey conducted among 357 US Millennials indicate that perceived ease of use of MP (PEOUMP); perceived usefulness (PUMP); and risk perception all influence attitude toward mobile payment (AttMP). System trust, socio-cultural influence, and AttMP all influence MP use intention. The paper discussed the limitations of the study and future research directions.

中国商业银行SBM效率实证分析——基于修正的三阶段DEA模型

鉴于现有研究对于银行产出效率的争论,基于2004-2009年我国27家商业银行的相关数据,本文构建了修正的三阶段DEA模型我国商业银行的产出效率进行了考察。研究结论发现:2004-2009年间商业银行的产出效率有了较大幅度的提升,且城市商业银行的产出效率要高于股份制商业银行,并进一步大于国有商业银行。修正后的商业银行产出效率有所增加,但由于规模因素的影响,资本充足率和准备金率对松弛变量的影响在国有、股份制和商业银行间呈现出不同的变化趋势,使得资本充足率和准备金率对松弛变量的影响存在着非线性关系,并进一步导致股份制和城市商业银行的优势地位有所减弱,国有商业银行的产出效率迅速提升。最后,本文得出了相应的结论和政策建议。
