What drives stickiness in location-based AR games? An examination of flow and satisfaction

Although location-based augmented reality (AR) games are popular in recent years, the motivates of the game’s stickiness still need further investigation. The main goal of this research is to investigate the antecedents of the game’s stickiness. This research develops a conceptual model and hypotheses based on the theory of flow and satisfaction to investigate the antecedents. An online questionnaire was developed and distributed on popular websites to collect data, and 1028 usable responses are collected from the players of Pokémon Go in Taiwan. The eleven hypotheses and control variables were validated by using structural equation modeling (SEM) techniques. Among the antecedents of the game’s stickiness in the model, the flow and satisfaction were found to have strong direct effects. The effects of control variables (age, gender, platform, game experience, and in-app expense) on the stickiness were significant as well. Moreover, telepresence, challenge, perceived control, curiosity, and concentration all have direct influences on the flow. Only perceived currency and responsiveness were found to have a direct impact on players’ satisfaction. The model demonstrated good explanatory power for flow and stickiness in the context of location-based AR game. The proposed model can provide insights to location-based AR game developers to design their games and marketing strategies.     

Understanding the role of competition in video gameplay satisfaction

One of the key elements in many video games is competition. Based on Self-Determination and Flow theories, this paper explores the process through which competition makes a video game satisfying. A structural model that examines the impacts of Situational Competitiveness (manipulated via modes of competition) and Dispositional Competitiveness (as a personality trait) on gameplay experience is proposed and validated. The results show that the perception of video game competitiveness has a strong effect on Flow experience and Satisfaction. While an individual’s personality impacts the perception of a game’s competitiveness, this perception can also be influenced by the mode of competition.     

Satisfaction with food-related life and beliefs about food health,safety, freshness and taste among the elderly in China: A segmentation analysis

This paper focuses on Chinese elderly’s life satisfaction with food, a specific and important domain of Chinese people’s daily life, with two purposes: first, to investigate the relationship between satisfaction with food-related life and life satisfaction among Chinese elderly; second, to segment Chinese elderly based on their beliefs about food health, safety, freshness and taste, and profile them by their life satisfaction, satisfaction with food-relate life, food-related goals, self-rated health status, self-rated economic status and socio-demographic characteristics. Data were collected by personal interviews conducted in Beijing with 452 participants above 60 years old from March to May 2018. The correlation between satisfaction with food-related life and life satisfaction in the present study was positive and higher than in other countries. Three distinct segments were identified: health and safety concerned (38.6%), hedonic and less health concerned (29.4%), and less safety and somewhat health concerned (32.0%). The level of satisfaction with food-related life of the elderly was the lowest among the health and safety concerned segment, neutral in the hedonic and less health concerned segment, and highest among the less safety and somewhat health concerned segment. The elderly’s food safety belief might play a more dominant role than other food attributes beliefs in their satisfaction with food-related life. Eating a healthy diet and eating a safe diet were perceived as the most important food-related goals while keeping food expenditure as low as possible was perceived as not important by participants. Implications for how to improve Chinese elderly’s satisfaction with food-related life and future research were discussed.     

Intention-behaviour gap and perceived behavioural control-behaviour gap in theory of planned behaviour: moderating roles of communication,satisfaction and trust in organic food consumption

This study examines the moderating effects of perceived communication, satisfaction and trust on the intention-behaviour gap and the perceived behavioural control (PBC)-behaviour gap in the theory of planned behaviour (TPB) model, using a quantitative research method. A nationwide panel-only online survey was conducted, resulting in 1011 usable responses from organic food consumers in Australia. Data were analysed statistically using SPSS v.25 and SmartPLS 3 software, and the hypotheses were tested using the partial least squares-based structural equation modelling (PLS-SEM) technique. The findings confirm that perceived communication, satisfaction and trust positively and significantly enhance purchase behaviour and lessen gaps in the intention-behaviour and PBC-behaviour relationships in the TPB model. This study also validates the TPB model and finds statistically significant results in support of all of its 14 hypotheses. It is the first such study to examine the intervention efficacy or moderating effects of perceived communication, satisfaction and trust on the intention-behaviour and PBC-behaviour gaps in the TPB model. Examining the mediational effect of behavioural intention in the TPB model and including the Australian context are among its other contributions. Organic food producers and marketers aiming for sustained, positive changes in consumer behaviour are encouraged to consider the findings and implications of this study.

基于邻居信息聚合的子图同构匹配算法

图匹配在现实中被广泛运用,而子图同构匹配是其中的研究热点,具有重要的科学意义与实践价值。现有子图同构匹配算法大多基于邻居关系来构建约束条件,而忽略了节点的局部邻域信息。对此,提出了一种基于邻居信息聚合的子图同构匹配算法。首先,将图的属性和结构导入到改进的图卷积神经网络中进行特征向量的表示学习,从而得到聚合后的节点局部邻域信息;然后,根据图的标签、度等特征对匹配顺序进行优化,以提高算法的效率;最后,将得到的特征向量和优化的匹配顺序与搜索算法相结合,建立子图同构的约束满足问题（CSP）模型,并结合CSP回溯算法对模型进行求解。实验结果表明,与经典的树搜索算法和约束求解算法相比,该算法可以有效地提高子图同构的求解效率。

Repurchase intention in B2C e-commerce—A relationship quality perspective

Information systems professionals must pay attention to online customer retention. Drawing on the relationship marketing literature, we formulated and tested a model to explain B2C user repurchase intention from the perspective of relationship quality. The model was empirically tested through a survey conducted in Northern Ireland. Results showed that online relationship quality and perceived website usability positively impacted customer repurchase intention. Moreover, online relationship quality was positively influenced by perceived vendor expertise in order fulfillment, perceived vendor reputation, and perceived website usability, whereas distrust in vendor behavior negatively influenced online relationship quality. Implications of these findings are discussed.
