文章从信息性社会影响和规范性社会影响视角,构建综合性问答网站用户信息采纳意愿的影响因素研究模型,并通过问卷调查和结构方程建模方法进行实证分析。结果表明：信息可信度和信息有用性对用户信息采纳意愿具有直接显著的正向影响,且信息可信度的作用更强。从信息性社会影响视角,发现信息质量和信源可信度是影响用户感知信息可信度和信息有用性的关键因素;从规范性社会影响视角,发现信息一致性对信息可信度产生显著的正向影响,信息评级正向显著影响信息有用性,而对信息可信度的影响不显著。 相似文献

[目的]社会化媒体与社交网络的迅猛发展,驱动银行开始在其网站中嵌入各种社会化工具,为用户提供社会化服务。在这种环境下,影响用户使用网上银行的因素较传统互联网环境相比可能会发生变化。因此本研究聚焦于社会化媒体环境,探究该环境下影响用户使用网上银行意愿的影响因素。[方法]通过情景式问卷收集用户数据,采用相关性分析、多元回归分析、方差分析等方法进行数据分析。[结果/结论]在社会化媒体环境下,信息支持不仅可以直接正向影响用户对网上银行的使用意愿,还可以通过网站设计对用户使用意愿产生间接影响;情感支持可以通过正向影响网站设计而对用户使用网上银行的意愿产生间接影响;感知有用性、感知易用性、网站设计均可以直接正向影响用户的使用意愿,而感知风险则对用户的使用意愿具有直接的负向影响。此外,主观规范虽不能直接影响用户使用网上银行的意愿,但可以通过感知有用性对其产生间接地影响。 相似文献

本研究采用结构方程模型,以同侪影响和感知价值为多重中介,对社交网络情境下社交支持对早期用户的新产品采纳意愿影响进行研究。结果表明:(1)同侪影响和感知价值在社交支持与早期用户的新产品采纳意愿的关系中共同起多重中介作用;(2)规范性影响和情感价值在社交支持与采纳意愿的关系中的中介效应强度远远高于其他路径;(3)同侪影响的两个维度并非独立存在,规范性影响对早期用户受来自同侪者的信息性影响有显著的促进作用;(4)感知价值的两个维度间也存在功能价值对情感价值的影响关系,新产品的功能价值对情感价值有显著影响。研究结论对指导社交网络情境下新产品在早期用户群体中的成功扩散有着重要理论和实践意义。 相似文献

The advent of social commerce has resulted in a new business model for e-commerce. Although studies on this business model have increased over time, they have paid less attention to its core business model: consumer-generated social influence on sales on a social commerce site. Therefore, in this paper, we examine the effect on sales of social sharing, such as Facebook “likes” and Twitter tweets, which generate social influence, using data from major social commerce companies. We find that consumer-generated social referrals regarding deals significantly boost sales in social commerce. When we examine deals involved in national sales, this finding holds only for Facebook but not for tweets. These findings have the implication for managers that not all social referrals are meaningful in increasing sales for their business. 相似文献

The ethical implications of the explosion of social media outlets for social work education are explored in this paper. Given that social work education has a dual focus, both of educating students and of socializing practitioners into the profession, the issue of the blurring between what is social and what is professional gains particular salience for both educators and students. Recommendations for educators to ethically address the need to maintain a consistent professional presence online and to avoid potentially harmful dual relationships with students are presented. These recommendations include: abstain from using social media or use only a static professional profile; use only university protected sites to promote collaboration with students in the classroom including all students to avoid any appearance of impropriety; use social media with the utmost discretion mindful of all the risks by creating a very select circle of friends, separating one’s personal site from one’s professional site; develop policies which include not friending any individual student or any current student and inform students about the policies. 相似文献

The ability of detecting infections at an early stage in clinical environments is an important clinical problem. When an infection is not diagnosed on time, it may not only affect the health of the infected patient, but also spread and infect other people.In this paper, we propose the development of a clinical decision support system (CDSS) for diagnosing infections using clinical signals from patients. This system is designed to be able to cope with small amounts of data (a single record per day and patient), making it convenient for environments under strict constraints (such as low resources or bad connectivity). Additionally, we have incorporated data from external sources, in order to enrich the quality of the models. In particular, we have considered social data arising from web searches, retrieved from Google Trends, as well as weather data.Clinical data was recorded between April 2018 and July 2019 in two nursing homes in Spain and one in Dominican Republic, where nurses had also tested patients for infections. Feature extraction was carried out by aggregating measurements from days before to the infection (lead) and after the infection was detected (lag), and these features were used to train supervised learning models. The best model attained using only clinical data attains an AUROC of 0.734. When data is enriched with external sources, this performance increases up to an AUROC of 0.798. In the case of prognosis (i.e., only measurements before the manual annotation of the infection are used) an AUROC of 0.719 is obtained using only clinical data, and up to 0.757 when combining additional sources of data.In conclusion, the CDSS provides a good recognition performance given the small amounts of data available. This performance can be increased by including social data, which are readily available, and can therefore be useful in scenarios where clinical data acquisition is expensive or unfeasible. 相似文献

HIV/AIDS conspiracy theories constitute a loosely grouped set of meanings that share the notion of secret collusion among allied parties. This paper traces one woman's etiological narrative of HIV/AIDS. Such embodied experience and cultural understanding when placed against the backdrop of current thinking on the topic in the United States builds a new framework for understanding the emergence and circulation of HIV/AIDS conspiracy theories as "counter-narratives" employed by individuals and publics in the face of the AIDS pandemic. Such counter-narrative creates a rhetorical space for challenges to power through the articulation of oppositional ideas about dominant scientific knowledge. Without a critical exploration of HIV/AIDS conspiracy theories that examines their emergence and effects as a form of discourse circulating in the public domain, public health advocates will not be able to trace and respond to these narratives' impact on HIV prevention efforts or consider their relevance for other emerging infectious diseases. 相似文献

从现代科学解释学和技术社会学的观点看,互联网与其说是一种具有高技术与“异托邦”特质的“另类空间”或媒介“物体系”,不如说是一种具有多方面工具理性气质的“社会工程体系”。互联网就是一种充满主体性、系统性、复杂性和互动性逻辑精神的社会工程。它是实际存在的,但因为处于虚拟环境中,所以对它的理解还须借助社会学的想象力。 相似文献

This study furthers investigation into exactly how Social CRM (S-CRM) is different from traditional CRM, and models the interrelationships between its capabilities. It is underpinned in dynamic capabilities theory, to explain how social media, as a resource all organizations use, can lead to differing performance outcomes. It is underpinned in seminal research into traditional CRM, but which does not cater for the disruptive nature of social media. We outline how S-CRM is a second-order dynamic capability consistng of a set of first-order integrative dynamic capabiliies that, when properly interrelated, lead to performance outcomes. We particularly model the role of S-CRM front- and back-office technology capabilities, customer engagement initiatives, and social information processes in driving customer relationship performance. Findings show that S-CRM is different from traditional CRM in a range of ways in the front- and back-offices, and provide a framework for researcher and managers in information systems and marketing to operate at strategic and tactical levels within S-CRM, while being congisant of both. 相似文献
