报告题目：Complement orsubstitute? Investigating the interdependence effectsamong mobile social apps

报告人：王创，华南理工大学工商管理学院的副教授。研究领域包括IT挑战和负面问题，社交媒体，社交网络和移动商务。在Information Systems Research, Journal of Management Information Systems, Journal of the Association for Information Systems, Information & Management, Decision Support Systems, Information Processing & Management, Electronic Commerce Research and Applications, Internet Research, and Journal of Services Marketing等知名期刊上发表论文若干篇。

摘要：Interdependence effects would arise when individuals consume two or more products simultaneously. However, comprehensive understanding and quantitative analysis of such interdependence effects in the use of mobile social apps are still limited. The few existing studies mainly considered whether the apps are installed together by unique devices, while the actual usage behaviors are totally ignored. The current study developed an adapted utility function model to quantify the interdependence effects and found that social apps satisfying users’ different psychological needs would be complementary at most times, while those apps gratifying similar psychological needs would also complement rather than substitute each other.

报告题目：How gamified MiniApp drives consumer citizenship behavior

报告人：徐嘉泓 广东工业大学管理学院研究生

摘要：Encouraging consumer citizenship behavior (CCB), such as recommendation, helping others, and feedback, is crucial to the growth of e-commerce firms. With firms increasingly adopt gamified MiniApps, consumers are expected to perform CCB in the e-commerce context. Drawing on the theories of Needs-Affordances-Features and Psychological Ownership, this study empirically tests the impact of gamification affordances on CCB and the mediating role of psychological ownership. Our qualitative study further clarifies the relationships among technical components (namely elements and features) and psychological construct (namely gamification affordances), unfolding the “black box” of gamified MiniApp. The findings provide important implications for both research and practice.

摘要：Social media harassment, a cyberbullying behavior, poses a serious threat to users and platform owners of social media. The growing body of social media harassment research has made it challenging for researchers and practitioners to comprehend the current state of knowledge. In this sharing, I will present our literature analysis of prior studies and discuss the research themes and patterns of social media harassment. I will also talk about a recent study on bystander reporting intervention of social media harassment. The study contextualizes the bystander intervention framework and reporting literature to social media in order to understand why bystanders report social media harassment. Our contextualized intervention framework focuses on three sociotechnical aspects—the online social environment, characteristics of the technology platform, and their interplay—that explain bystander reporting on social media platforms. We tested the model using data gathered from 291 active Facebook users. Most hypotheses were supported. We expect that this study contributes to the cyberbullying literature by offering a novel sociotechnical explanation of mechanisms that shape bystanders’ willingness to report social media harassment. Further, this study offers insight into how to build safer and secure social media platforms for all users.

报告题目：The relative effect of the convergence of product recommendations from various online sources

报告人：许景俊 (Xu J.J. David)，香港城市大学信息系统系副教授，研究领域包括人机交互，社交媒体，电子商务，技术采用，虚拟现实和人工智能。在MIS Quarterly, Information Systems Research, Management Science, INFORMS Journal on Computing, Journal of Management Information Systems, Journal of AIS等国际知名期刊上发表论文若干篇，并获得了ICIS 2020最佳副编辑奖，担任Information Systems Research和Information Systems Journal副编辑。

摘要：Most previous studies about online product recommendation sources (recommendation agents [RAs], consumers, and experts) have been limited to the evaluation by a single source on a website. Thus, the relative influence of convergent recommendations from different sources on consumers’ acceptance of the advice remains largely unknown. We draw upon and extend the product uncertainty model to theorize how the convergence of recommendations from various sources differentially influences customers’ acceptance of recommendations. Our experiments show that the recommendation convergence between RAs and experts leads to the greater recommendation acceptance of the jointly recommended products than the convergence between experts and consumers or convergence between RAs and consumers. The rationale is that RAs best reduce fit uncertainty, and experts best reduce description and performance uncertainties. Experts and RAs complement each other by reducing all three dimensions of product uncertainty. Online merchants are advised to incorporate multiple sources into their websites, including sources (i.e., RAs and experts) that play complementary roles in reducing product uncertainty.

报告题目：From watch to buy: The impact of firm self-broadcasting in live streaming commerce

报告人：李展尧广东工业大学管理学院研究生

摘要：Firm self-broadcasting (FSB), an emerging paradigm of live streaming commerce hosted by firms, has gained increasing popularity. Aiming to identify the monetizing process in FSB from the firms’ perspective, this research collects data based on 2327 broadcasting records of 312 firms from multiple sources and confirms a positive relationship between FSB popularity and sales performance as well as two important moderators, namely information load and product type. Our content analysis results suggest information load has an inverted U-shaped moderating effect, and the effect of both FSB popularity and information load on sales performance are different among experience-1, experience-2, and search product. Besides, viewers can hold the highest information load of experience-2 products. These findings enrich our theoretical understanding of the social exchange theory, information processing theory, and product classification literature, meanwhile confirm the significance of FSB and a rich set of actionable marketing strategies in the live streaming commerce context.

摘要：本课题分析大数据+知识管理的新场景下的知识创造。SECI（社会化、外化、组合、内化）理论是一种经典的知识创造理论，在信息系统设计、组织管理等领域被广泛接受。随着数字技术的飞速发展，组织通过社交问答平台进行知识创造的方式，构建了高流动性和快速信任构建的情境，该情境已经超出了SECI理论的范畴，同时知识创造理论与实际操作存在差距。目前对SECI具体过程的研究还很少，因此很难理解它在数字时代的变化和运作。为了填补这一空白，我们从社交问答网站收集问答数据，设计了一种结合深度学习和计量经济学模型的创新方法来探索数字时代的知识创造过程。提出了基于问答对数据知识资产变化的多损失卷积神经网络模型识别SECI的具体过程。之后我们用Mann-Kendall检验(MK检验)来探究过程强度随时间的变化，用Granger因果检验来探究SECI四个部分的因果关系来发现序列变化。结果表明，知识创造的四种过程强度可以随着时间增强或变弱。此外，在数字化知识创造中，S、E、C、I之间存在线性和非线性关系且存在跳跃。该研究从长期视角拓宽了知识创造理论研究，提供了一种通过数据科学探索理论的方式，结合实际场景为管理者提供了数字化时代下有效的知识创造实践。同时，课题涉及多个知识平台系统设计的问题，包括专家智能推荐，答案智能推荐，个性化知识推荐等，最终期望形成一个基于大数据驱动的知识管理框架。

报告题目：Coupon or free shipping? Effects of price promotion strategies on online review

摘要：Price promotions can be implemented by either discounting a product’s base price (e.g., offering a coupon) or reducing one of its surcharges (e.g., free shipping). This study examines how the two prevalent price promotion strategies affect online review ratings differently as a function of the temporal distance between purchase and review. Drawing upon the framing literature and construal level theory, we argue that whereas free shipping should increase review ratings regardless of temporal distance, coupons should increase review ratings through perceptions of monetary savings when temporal distance is close but decrease review ratings through low perceive quality when temporal distance is far. Consistent with this argument, our analysis of online consumer reviews from an e-commerce website matched with actual transactional data finds that coupons have a positive effect on review ratings in the short run but a negative effect in the long run. In contrast, free shipping has a consistently positive effect on review ratings over time. A text-mining analysis of the review contents reveals patterns that are consistent with the proposed underlying mechanisms. We then conduct two lab experiments that manipulate temporal distance and construal level respectively with real spending and consumptions to provide converging evidence for the differential effects of coupon vs. free shipping on review ratings over time, and additionally demonstrate the underlying processes due to perceptions of monetary savings and perceived product quality.

报告题目：Empowering patients using smart mobile health platforms: Evidencefrom a randomized field experiment

报告人：郭熙铜，哈尔滨工业大学教授、博士生导师，电子健康研究所执行所长，主要研究方向为电子健康。2017年入选国家高层次人才特殊支持计划青年拔尖人才，2016年获国家优秀青年科学基金，2012年入选教育部新世纪优秀人才和“香江学者计划”。在MISQ, ISR, JMIS, JAIS, EJIS, ACM TMIS, DSS, IJEC, I&M, ICIS等国际主流学术期刊和会议发表、接收80余篇学术论文，其中SCI/SSCI论文50余篇，主持国家自然科学基金重点项目“智能健康信息服务管理”。

摘要：With today’s technological advancements, mobile phones and wearable devices have become extensions of an increasingly diffused and smart digital infrastructure. In this paper, we examine the emerging mobile health (mHealth) platform and its health and economic impacts on the outcomes of diabetes patients. To do so, we partnered with a major mHealth firm that provides one of the largest mobile health app platforms in Asia specializing in diabetes care. We designed and implemented a randomized field experiment based on 9,251 unique observations on blood glucose values and 55,359 unique observations on detailed patient health activities (e.g., steps, exercises, sleep, food intake) and app usage logs from 1,070 diabetes patients over three months together with a follow-up survey after five months. Our main findings show that mHealth technology adoption can lead to a reduction in diabetes patients over time. Patients who adopted the mHealth application undertook higher levels of daily exercise, consumed healthier food with lower daily calories, walked more steps and slept for longer times a day. Our findings suggest that mHealth technology can help patients self-regulate their health behavior. This can lead to long-term behavioral modifications towards a healthier dietary and life style, which ultimately leads to an improvement in their health outcomes (e.g., glucose values, hospital visits). Interestingly, we also found personalized mobile message with patient-specific guidance showed an inadvertent effect on patient app engagement, life style changes, and health improvement due to stress, which in turn, can demotivate patients from self-regulating behavior. Overall, our findings indicate the potential value of mHealth technologies, as well as the importance of mHealth platform design in achieving better healthcare outcomes.

报告题目：Does the doctor look professional? Understanding the role of doctor profile picture in online healthcare markets

报告人：杨化龙 广东工业大学管理学院讲师，博士

摘要：Selecting an appropriate doctor within the online healthcare market is likely to be an important decision for patients. Because of the nature of electronic environments, patients in online healthcare markets may suffer from risks and uncertainties due to the virtual presence of doctors. Due to the lack of face-to-face communication, profile picture is the basis for patients to judge the image of doctors in the online healthcare market. These profile pictures may affect the patient’s perception of the doctors’ profession and affinity, and thus become an important clue for the patient’s choice and decision-making. Although extensive studies have explored the influencing factors on patients’ choice, scant literature has investigated the role of profile pictures in online healthcare markets. Our study explores this research issue through the mixed research method. First, this paper collects data from a real online healthcare market to construct an empirical model to analyze the impact of doctors’ profile pictures on patient choices as well as the moderating effect of disease types. Second, we designed a laboratory experiment combined with eye movement trajectory to explore how profile pictures affect patients’ perception of doctors’ professionalism and affinity.
