This paper applies text analytics to study how the orientation of an endorsement strategy affects the public's willingness to participate in citizen science projects. Using 850 citizen science projects with 1,243 endorsements from an online citizen science platform Experiment.com as corpus, the orientation of the endorsement strategies is detected using the naïve Bayesian inference model with a Laplace estimator. Our results inform that 39% of the endorsements are persona-oriented while 61% are content-oriented. A persona-oriented endorsement strategy draws more participants but reduces the per capita invested. A content-oriented endorsement strategy has the opposite effect. Further, the project initiator's identity strengthens or weakens the effect of the endorsement orientation strategy. In the number of participants model, the projects initiated by the professional scientists and research students are positively moderated by persona-orientation endorsements, whereas the projects initiated by the amateur researchers are negatively moderated. The converse holds for the per capita invested model. 相似文献

People are increasingly searching for information in social Q&A communities, especially through a new form of paid knowledge product, namely, live course. Such course provides a way for users to interact synchronously with content creators online. However, how this knowledge product is accepted and why users pay for it deserve attention from researchers. In this study, a research model was developed based on information foraging theory (IFT) and social information foraging (SIF) theory to analyze users’ information processing and evaluation when making payment decisions. Our research model was validated by collecting subjective and objective data from a Chinese social Q&A community that has been successful in offering live course services. We found that perceived quality of free content, perceived credibility of content creators, and perceived quantity of participants positively influence users’ willingness to pay, and thus, positively affects users’ payment behavior. Unexpectedly, social endorsement negatively moderates the relationship between willingness to pay and payment behavior. This study enhances the theoretical understanding of the drivers of users’ payment for live courses in social Q&A communities. For IS practice, our findings provide unique insights for community managers and content creators on how to operate paid knowledge products appropriately and effectively. 相似文献

With the prevalence of social media and social networking, social commerce is becoming increasingly popular in both business and research areas. As in other types of e-commerce context, trust is also indispensable in social commerce. In this study, two types of trust have been discussed. This study represents an initial attempt to provide an integrated view of particularized trust in social commerce, including particularized trust antecedents, trust transfer and trust performance, so as to promote trust formation in social commerce. Using data collected from 614 social commerce users, we demonstrate that trust disposition, quality-assured shared information, familiarity and endorsement by other members are four antecedents of particularized trust. The results also indicate particularized trust can be transferred into system trust, and particularized trust only exerts positive effect on social WOM intention while system trust only exerts positive effect on social shopping intention. Furthermore, we prove perceived similarity can strengthen the relationship between trust disposition and particularized trust as well as the relationship between quality-assured shared information and particularized trust. 相似文献

Social question-and-answer (Q&A) sites have the potential to serve as a useful source of online information based on their content-focused and collaborative nature. Although previous research has examined various attributes of high-quality information on social Q&A sites (e.g., best answers), relatively less attention has been paid to what affects users’ credibility assessments of information in the social Q&A context. The present study developed a social Q&A platform-specific framework for web credibility assessment, including 21 criteria under six types of web credibility, based on a literature analysis and case study of two online Q&A communities, Stack Exchange and Wikipedia Reference Desk. Using the selected sites’ policies and guidelines (n = 46) as the source of evidence, the case study revealed that content-related attributes (e.g., evidence-based, pertinence) were most frequently identified (12 of 21 criteria) as potential cues and heuristics for web credibility assessments of social Q&A sites, followed by author-related (five of 21; e.g., reputation) and design-related (four of 21; e.g., engaging design) factors. Design-related criteria were rarely included in previous models of web credibility on social Q&A or similar peer-knowledge production platforms. However, our findings showing that both Stack Exchange and Wikipedia Reference Desk have policies regarding all four design-related criteria in our framework—engaging design, moderation, design appropriateness, and ease of use—indicate the potential influences of design features on users’ web credibility assessment on social Q&A sites. Some differences emerged between the two cases, such as policies regarding the answerer's credentials or semantic accuracy that are present on Wikipedia Reference Desk but absent on Stack Exchange. Such differences in the sites’ policies reflect how they position themselves as social Q&A communities—Wikipedia, of which Wikipedia Reference Desk is a part, as an encyclopedia, and Stack Exchange as a community-based platform for learning, sharing knowledge, and building careers of users. 相似文献

The spreading of misinformation and disinformation is a great problem on microblogs, leading user evaluation of information credibility a critical issue. This study incorporates two message format factors related to multimedia usage on microblogs (vividness and multimedia diagnosticity) with two well-discussed factors for information credibility (i.e., argument quality and source credibility) as a holistic framework to investigate user evaluation of microblog information credibility. Further, the study draws on two-factor theory and its variant three-factor lens to explain the nonlinear effects of the above factors on microblog information credibility. An online survey was conducted to test the proposed framework by collecting data from microblog users. The research findings reveal that for the effects on microblog information credibility: (1) argument quality (a hygiene factor) exerts a decreasing incremental effect; (2) source credibility (a bivalent factor) exerts only a linear effect; and (3) multimedia diagnosticity (a motivating factor) exerts an increasing incremental effect. This study adds to current knowledge about information credibility by proposing an insightful framework to understand the key predictors of microblog information credibility and further examining the nonlinear effects of these predictors. 相似文献

The purpose of this study is to investigate factors influencing students' perception of the credibility of scholarly information on the web. In addition to the four types of source credibility proposed by previous studies (presumed credibility, reputed credibility, surface credibility, and experienced credibility), this study shows that two other types of source credibility (verifiable credibility and cost-effort credibility) play a significant role in shaping students' perceptions of credibility. Circumstances that affect students' willingness to accept scholarly information on the web are identified. Implications for web system design are also discussed. 相似文献

在创新驱动发展的趋势下,内生资源是决定企业战略导向及获取竞争优势的重要来源,对于外部资源约束下“小而弱”的新创企业更是如此。因此,新创企业创新发展的本源必须回归企业内部,既要重视对冗余资源的开发利用,也要加强对创业导向的培育;而组织内部“资源-战略”的转化过程必然与外部制度环境息息相关。基于此,本文通过2011—2016年间252家创业板企业为研究对象,分别验证了非沉淀冗余、沉淀冗余资源对创业导向的倒U型影响;并分别以社会网络为非正式制度、以知识产权保护为正式制度的调节因素,检验了不同制度对于冗余资源与创业导向的差异化调节效果。以此完善了对资源基础观、创业机会观及制度观的整合研究。 相似文献

探索和利用式的创新选择对绩优企业的长远发展至关重要。整合绩效反馈理论和注意力基础观,探讨了基于社会和历史期望的绩效顺差对企业创新选择的不同影响机制。基于中国A股上市公司2011到2016年的面板数据,结合文本分析法,研究发现：一方面,基于社会期望的绩效顺差加强了高管团队利用式创新注意力;基于社会和历史期望的绩效反馈越不一致,以上关系越弱。然而,基于历史期望的绩效顺差加强了探索式创新注意力;两种绩效反馈越不一致,上述关系越弱。另一方面,创新注意力在绩效顺差与企业的探索式（或利用式）创新之间起到了完全中介作用。研究结果揭示了绩优企业选择探索式或利用式创新的内在机制,为正确认知绩效顺差提供了启示。 相似文献

Composite diversity among team members is one of the noteworthy but neglected issues for its contingent effect on knowledge management processes. This paper presents that these often contingent and sometimes bipolar effects of composite diversity occur in their relationship with knowledge sharing, which is one critical element for knowledge management. Nevertheless, we argue that this contingency does not stem from the diversity per se, but from the social-cognitive state (i.e. social capital) that moderates in this diversity-sharing relationship. In addition to the conceptual deductions, we conducted a series of semi-structured interviews in a real-life group setting as a preliminary endorsement for our theoretical exploration; this effort serves as a setout in assisting the illustrative conceptual deductions but not an attempt to be one large-scaled empirical piece of testing that should consider the generalizability more seriously. Implications for group practices and group dynamics in knowledge-sharing imperatives are discussed finally. 相似文献

Consumers increasingly rely on social media to obtain product information. The vlog, a new kind of social medium, has been adopted by sellers to connect with consumers. Through this platform, sellers can cooperate with vloggers to recommend products or services to consumers. Extending beyond the previous perspective that consumers’ perceptions and behaviors are influenced by vloggers’ attributes, we herein investigate the influence of recommendation content. Drawing on the means-end chain framework, this paper investigates how the attributes of recommendation content affect consumers’ intention to adopt (i.e., follow) the recommendation. Data collected from 513 respondents provides support for the proposed influences. The results indicate that source credibility, content diagnosticity, and content serendipity drive consumers’ recommendation adoption intention. This research contributes to the literature on rec-vlog marketing by clarifying the significant role of recommendation content. Implications are discussed regarding these findings. 相似文献

Blogs have recently become an influential medium and have demonstrated enormous marketing power. Consumers can freely conduct ongoing information searches through this new channel. However, the credibility of blogs plays an important role in creating opportunities for positive customer experiences that can shape consumers’ product/service purchase intentions and decisions. In light of this observation, this study proposes a theoretical framework that delineates the relationship among information credibility, customer experiences, and purchase intention in the blog environment. Data collected from 468 subjects in specific corporate blogs provide support for the proposed model using partial least squares (PLS). The results indicate that information credibility is critical for facilitating customer experiences, which, in turn, is necessary to enhance purchase intention. Additionally, greater involvement with blog significantly increases the effect of customer experiences on purchase intention. The detailed theoretical and managerial implications are presented. 相似文献

Transaction uncertainty is an impediment to customer satisfaction and remains a problem in the dual-channel retailing context. Most consumers use web stores for information and evaluation. This process influences their subsequent retailer selection and consumer satisfaction. In this study, the retailer brand, as the source of transaction information, is considered as a solution to the problem of transaction uncertainty. Brand attractiveness, the affective aspect of brand, is identified as an affective-based uncertainty mitigator and is considered together with brand credibility, the cognitive aspect of brand. Drawing on the source attractiveness/credibility model, retailer brand attractiveness and credibility are proposed and confirmed to reduce transaction uncertainty, in turn improving customer satisfaction. The moderating role of online–offline channel integration on the uncertainty reduction effect of retailer brand attractiveness and credibility is investigated. Online–offline channel integration has been found to be the essential condition for the uncertainty reduction effect of retailer brand attractiveness. Online–offline channel integration is also found to form a synergy with retailer brand credibility in reducing uncertainty. These findings show that the web stores of dual-channel retailers should invest in brand attractiveness and credibility orderly and coordinate brand investment with online–offline channel integration. 相似文献

已有研究将社会资本作为获取外部知识的渠道,隐含假设是社会资本具有知识流入效应。由于知识分享的相互性,社会资本实质上还具有知识流出效应。已有研究主要强调知识流入效应,是因为私有协同创新中的知识分享存在有意识的控制机制和组织边界,从而有效地抑制了知识流出。在共有协同创新网络中,创新团队间边界模糊且知识分享不受限制,导致知识流出效应显著增强。本文以共有协同创新网络为背景,探讨创新团队社会资本对新产品流行度的差异化影响以及如何控制该影响。通过收集开源平台SourceForge上1595个项目和8186个志愿者信息,结果发现创新团队度中心性对新产品流行度具有倒U型作用;桥中心性和接近中心性可提升新产品流行度。团队知识利用则有利于延缓社会资本的负面效应,强化其正面效应。 相似文献

Drawing on the stressor-strain-outcome framework, this study investigates how information irrelevance and overload induce social network fatigue, and the relationship of these variables to users’ information avoidance behavior. It also examines the conditions under which social network fatigue is more likely to be translated into information avoidance behavior. The analysis of data collected from 341 users of WeChat Moments suggests that information irrelevance directly leads to information avoidance behavior, and social media fatigue as a mediator partially mediates the impact of information overload on information avoidance behavior and fully mediates the impact of social overload on information avoidance behavior. Furthermore, time pressure strengthens the effect of social network fatigue on information avoidance behavior. This study fulfills the identified need for an in-depth investigation of actual discontinuous behavior in social network services (SNSs) by investigating information avoidance behavior and its antecedents. The findings provide SNSs providers with guidelines on how to manage users’ behavior so that they remain active users of the SNSs. 相似文献
