Gender and culture: do they matter for norms?

In a natural experiment, we observed that the influence of a norm depended upon the gender and cultural background of participants. Both gender and cultural background contributed to the effect of peer pressure that partly controlled against the act of cheating among participants as they completed a group task. Furthermore, both factors served to describe the characteristics of hardworking individuals in the group. We therefore conclude that the effectiveness of a norm in a group is expected to depend upon the presence of hardworking individuals therein.

论企业信用关系中的道德支撑

市场经济是以理性化为特征的信用经济或法治经济,需要以自由、平等、信用和契约为基础建立一种普遍性的交换关系。目前,我国正处在经济体制转轨时期,市场规则和市场秩序尚不健全,离开道德主体人格的塑造,离开政府信用与企业信用关系的良性互动,构建和谐社会只能是一句空话。为了切实发挥道德的调节功能,不仅要在全社会范围内建立符合社会主义核心价值体系内在要求的道德规范,还要提高政府的公共管理水平和社会参与者的整体素质。只有这样,才能发挥伦理道德这种“支持性资源”的支撑作用,促进我国社会经济的又好又快发展。     

More gain,more give? The impact of brand community value on users’ value co-creation

Users' value co-creation behaviors contribute to the prosperity of brand communities as well as brand performance. This article aims to answer a basic question: are brand community users who obtain more value from the brand community more willing to co-create value? If so, why and under what conditions? Drawing from reciprocity theory, this study proposes that information value and social value lead to value co-creation by evoking users' reciprocity norm, and this effect depends on their self-presentation in the community. Results based on structural equation modeling combining survey data and archival data largely validate this framework, revealing that the reciprocity norm mediates the influence of brand community value on value co-creation. Additionally, information value increases value co-creation only when the level of self-presentation is high, and the positive effect of social value is not altered by self-presentation. By uncovering the mechanism and boundary conditions of how brand community value affects users’ value co-creation behaviors, this study extends the current literature on value co-creation and provides important practical implications.     

Structured low-rank matrix completion for forecasting in time series analysis

This paper considers the low-rank matrix completion problem, with a specific application to forecasting in time series analysis. Briefly, the low-rank matrix completion problem is the problem of imputing missing values of a matrix under a rank constraint. We consider a matrix completion problem for Hankel matrices and a convex relaxation based on the nuclear norm. Based on new theoretical results and a number of numerical and real examples, we investigate the cases in which the proposed approach can work. Our results highlight the importance of choosing a proper weighting scheme for the known observations.     

Exploring the visitors' decision-making process for Airbnb and hotel accommodations using value-attitude-behavior and theory of planned behavior

Accommodation purchase decision is a complex field that makes predictions of revisit intentions hard to examine. Our work explores psychological factors motivating visitors' decision-making concerning accommodation purchases by integrating the theory of planned behavior and value-attitude-behavior model. Using a group of multiple informants in Swiss universities, we performed partial least squares structural equation modeling to assess the impacts of subjective norm, attitude and perception of quality on visitors' revisit intention and loyalty in Airbnb and hotel contexts. Although the influence of said factors on purchase decisions varies in the two contexts, results suggest that subjective norm has an indispensable role in prompting revisit intention towards Airbnb and hotel accommodations. This paper's findings advance our understanding of visitors' decision-making processes concerning traditional hotels and accommodation establishments operating in sharing economy platforms.     

Factors of electric vehicle adoption: A comparison of conventional and electric car users based on an extended theory of planned behavior

Increasing the share of battery electric vehicles (BEV) in the total car fleet is regarded as a promising way to reduce local car emissions. Based on online surveys in Denmark and Sweden, this study compares BEV users' (n = 673) and conventional vehicle (CV) users' (n = 1794) socio-demographic profiles, attitudinal profiles, and mobility patterns. In line with previous research, BEV users are typically male, highly educated, have high incomes, and often more than one car in their household. Additionally, BEV users perceive less functional barriers toward BEV use and have more positive attitudes and norms than CV users. The different profiles of these user groups suggest a separate analysis of potential factors of BEV adoption in both groups. In regression analyses, CV and BEV users' intention to use/purchase a BEV is modeled based on factors of the Theory of Planned Behavior extended by personal norm, perceived mobility necessities, and BEV experience. For CV users, symbolic attitudes related to BEVs are the most important factor of intention, while perceived functional barriers in terms of driving range are most relevant for BEV users' intention. How BEV users cope with trips of longer distance seems of particular relevance. In multiple car households, we found the percentage of actual BEV usage related to the type of other cars in the household, perceived functional barriers of BEVs as well as (successful) behavioral adaption to longer trips by BEVs. Based on the results, we discuss ways to increase BEV adoption for current users and non-users.     

Can staying overnight affect traveler satisfaction? Evidence from a gambling destination

Given that satisfied travelers tend to become repeat customers and spread positive word of mouth, destinations must induce travel satisfaction to increase their income. Travelers may face increasing physical and mental challenges during their travel that can undermine their travel experience, and staying overnight in a destination can improve the satisfaction of travelers by refreshing their energy. Given its important role in increasing the revenues of certain destinations such as Macau, staying overnight is strongly encouraged among travelers. However, the relationship between staying overnight and traveler satisfaction in the casino context has never been studied. By conducting a survey among 17,742 travelers in Macau, this study explores the moderating effect of staying overnight on the relationship between travel experience and satisfaction. The results indicate that staying overnight strengthens (reduces) the negative effect of visiting frequency (outside-Macau casino experience). However, staying overnight has no moderating effect on such relationship when the negative influence of first-time visit is considered. These findings also provide implications for tourism researchers and practitioners.
