大数据、人工智能与厂商竞争路径

经济学对市场竞争路径的学理性分析，主要集中在价格确定、产量确定、规模经济、产业组织等方面，而对科技进步引发市场竞争路径的变化并没有足够的关注。其实，市场竞争路径变化的底蕴是科技进步，只是经济学家在分析市场竞争路径时偏好于将科技因素作为外生变量处理。大数据和人工智能等的发展可谓是一场史无前例的科技革命，它对人类经济活动产生广泛而深刻的影响主要表现为：大数据及其运用怎样影响厂商投资经营，大数据与机器学习等人工智能手段相融合会在哪些方面改变厂商竞争路径，厂商如何提高数据智能化和实现网络协同化，在什么样的条件下会出现行业垄断，等等。文章的基本分析观点是：厂商竞争路径变化是贯穿于大数据、互联网和人工智能等相互融合过程的一种现象，这种现象对应于新科技进步和运用的不同层级；微观经济分析需要将新科技因素作为内生变量，通过分析大数据、机器学习与厂商竞争路径之间的关联，揭示厂商竞争路径变化机理以及由此引致的产业组织等问题。     

Optimal capacity and operation design of a robot logistics system for the hotel industry

This study introduces an optimal capacity and operation design of a robot logistics system that can reduce human workload in the hotel industry. In hotels, there are several duties that can be replaced by robots such as accompanying guests to the certain areas, delivering specific items to the guest rooms, and transporting some items that guests want to be removed from the guest rooms. To apply the robot logistics system in the hotel industry, the capacity and operation design should be prepared adequately. For that, a mathematical model-based optimization technique is used to decide the number of robots with the concept of minimizing total investment cost and to derive the optimal job assigning with the purpose of maximizing total covered jobs. In addition, a numerical example is performed to validate the proposed mathematical model and the sensitivity tests are examined to reflect the random features.     

Towards an integrated model for the transference of environmental responsibility

This research explores how environmental responsibility transfers to others. Although environmental responsibility is one of the most debated topics in environmental management literature, a framework describing how a teacher's environmental responsibility shapes the student's environmental responsibility is still lacking. Adopting emotional contagion theory as a lens, the paper addresses this issue via the mediation of emotional contagion and the moderation of a teacher's environmental concern. Based on a survey of teachers and students (N = 283) conducted in Pakistan, our findings provide evidence that a teacher's environmental responsibility can better transfer to students via emotional contagion. Additionally, our data establish that the transference of environmental responsibility from teachers to students via emotional contagion is more effective when the teacher has a high level of environmental concern than when he or she has a low level of environmental concern. Finally, the authors discuss the implications for policy in detail.

How do empowered employees engage in voice behaviors? A moderated mediation model based on work-related flow and supervisors’ emotional expression spin

The study examines the impact of empowerment on promotive and prohibitive voice behaviors in a moderated mediation model, suggesting work-related flow as a mediator and supervisors’ emotional expression spin as a moderator for hospitality employees based on affective event theory. The proposed model was tested using longitudinal matched data collected from 142 restaurant employees and their supervisors across multiple time stages in China. Analysis found that work-related flow mediated the relationships between empowerment and employee promotive and prohibitive voice behaviors, and supervisor emotional expression spin moderated these mediation links. The theoretical and practical implications of these findings for hospitality researchers and industry practitioners are discussed.     

Taking superintelligence seriously: Superintelligence: Paths,dangers, strategies by Nick Bostrom (Oxford University Press, 2014)

A new book by Nick Bostrom, Superintelligence: Paths, Dangers, Strategies, is reviewed. Superintelligence explores the future of artificial intelligence and related technologies and the risks they may pose to human civilization. The book ably demonstrates the potential for serious thinking aimed at the long-term future. Bostrom succeeds in arguing that the development of superintelligent machines will, if not properly managed, create catastrophic risks to humanity. The book falls short in some respects, and some sections are more compelling and novel than others. Overall, however, Bostrom’s book succeeds in demolishing the “null hypothesis” according to which the possibility and risks of superintelligence can continue to be ignored, and is a must-read for those interested in the long-term future of humanity.     

Does emotional labor moderate customer participation and buying?

Two studies examined whether employees’ emotional labor as perceived by customers, moderates the relationship between customers’ participation and money spent. In Study I, 30 in-depth interviews were conducted with customers to examine participation during shopping as well as customers’ awareness of their service employees’ behaviors. The interviews revealed two types of customer participation: emotional engagement and physical effort. Based on Study I, Study II investigated 114 customers, and the moderating role of perceived employees’ emotional labor on the relationships between customer participation and spending money. Even when customers were highly involved in the purchasing process, they spent less money when they observed employee inauthenticity as manifested in Surface Acting. However, Deep Acting positively moderated the relationship between customer participation and spending money. These findings help shed light on the circumstances in which customer participation is strengthened (leading to greater spending) or weakened.     

Does hospitality diversity education make a difference in undergraduate students’ emotional intelligence

Soft skills are typically referred to as the attributes exhibited or contained by an individual that display his/her ability to interact with others. Two types of soft skills that are often discussed within the hospitality industry are diversity awareness and emotional intelligence. Diversity may be explained or defined as a state of unlikeness, the conditions of being different, and all things that make us different. Areas where differences may exist include race, ethnicity, gender, sexual orientation, socio-economic status, age, physical abilities, religious beliefs, political affiliation and emotional reaction. Emotional intelligence (EI) has been defined as the ability to perceive, understand, regulate, and harness emotions in the self and others. How one deals with emotion is one characteristic that varies from culture to culture. Research has shown that EI may be a contributing factor in a moment of truth being considered a failure or success. The purpose of this study was to examine if undergraduate student EI scores change after completing a diversity issues course. Students completed the Assessing Emotions Scale on the first class day. At the conclusion of the 15-week course covering approximately 20 diversity issues concepts students completed the same EI assessment. Paired sampled t-testing was conducted to determine whether mean differences existed when comparing post and pre-course scores. Results of this study suggest that certain components of EI are significantly changed after taking the diversity issues course.
