The emergence of social media has fundamentally changed the way of scholarly communication and allows for scientific research to be shared at an unprecedented speed and scale. While many studies have discussed what papers attract most online attention, how they prevail online is unclear. In this paper, we explore the diffusion patterns of ~170,000 papers with different journal tiers from 2012 to 2019 based on over 3 million Twitter mentions. We first categorize journals by the elite (the top of Q1) and non-elite (Q2~Q4) according to their journal impact factor quartiles, then use network analysis and time series analysis to characterize papers’ dynamic diffusion process, and finally discuss papers’ engaged users and disciplinary contexts. Results show that though elite journal papers spread significantly faster and more broadly than non-elite, some non-elite journal papers reached a sizable audience. For non-elite journal papers, a decent size of social media reach can be achieved through the aid of highly influential users or multiple waves of small spread that span a long period. As a result, popular non-elite journal papers tend to be more viral than the elite, focusing discussions around topics close to daily life. This study provides a new perspective to characterize the diffusion process of scientific papers and helps to further enhance the understanding of such a process.  相似文献

People express themselves through posts or selfies with brands and activities on social networking sites (SNSs) such as Facebook and Instagram. This user-generated content provides adequate social information that may elicit the emotions of users who are exposed to such content on these online platforms. Although academic researchers have focused on factors affecting users’ emotions on SNSs, how users reconcile both positive and negative emotions to their attitude and behavior in triadic interactions remains unclear. The current study attempted to answer this research question through the lens of social comparison theory by investigating the effects of tie strength and focus of attention as two forces eliciting online social comparisons on emotional consequences measured through pleasure and envy. Moreover, the dualistic effects of the two distinct types of envy, namely benign and malicious, and the effect of pleasure on users’ approach and avoidance behavior were explored and hypothesized. The results indicated that strong ties triggered more benign envy compared with malicious envy. Furthermore, benign envy positively affected brand attitude and SNS avoidance in terms of exhaustion, whereas malicious envy negatively influenced brand attitude and increased the likelihood of SNS avoidance in terms of both exhaustion and discontinuance.  相似文献

A growing number of enterprises begin to utilize user-generated content (UGC) to help build brand awareness and loyalty on social media platforms. Thus, it is important to investigate what makes UGC more helpful under the new social media environment. This study attempts to identify the influence mechanism of UGC helpfulness by examining the systematic impacts of argument quality and source reliability, especially considering the effects of creator interactivity. Using a dataset of product-related UGC in a popular social media app, our empirical study finds that the detailedness, readability, and objectivity of the content, as well as the social recognition and popularity of the creator, all have a significant impact on UGC helpfulness. Furthermore, the results indicate that creator interactivity plays a vital role in building UGC helpfulness by moderating other factors. This study contributes to both UGC and social media literature by proposing a comprehensive model to better understand UGC helpfulness. It also provides several practical insights for content creators to improve their online performances.  相似文献

News source evaluations based on fact-checking can help curb the consumption and spread of fake news on social media. Prior research has primarily considered source evaluations with intuitive icons that indicate whether or not news sources are reputable. But can we increase the power of these icons by adding more detailed information about the evaluation that explains the reasons for the icon? What additional benefit would such evaluation details bring? Would they have the same effect for both positive and negative evaluations? We conducted two online experiments to understand the effects of a source evaluation icon (a positive or negative summary of the evaluation) and more detailed evaluation information explaining the reasons for the icon. Our results show an asymmetric effect of positive and negative icons and details. Negative icons reduced the believability of the articles, but adding evaluation details supporting the icon had no additional effect. In contrast, positive icons had no significant effects, but adding evaluation details significantly increased believability. We also found that users were more likely to view the evaluation details when the content of the article aligned with their pre-existing opinions, but the valence of the icon (positive or negative) did not affect this decision.  相似文献

Stress and depression detection on social media aim at the analysis of stress and identification of depression tendency from social media posts, which provide assistance for the early detection of mental health conditions. Existing methods mainly model the mental states of the post speaker implicitly. They also lack the ability to mentalise for complex mental state reasoning. Besides, they are not designed to explicitly capture class-specific features. To resolve the above issues, we propose a mental state Knowledge–aware and Contrastive Network (KC-Net). In detail, we first extract mental state knowledge from a commonsense knowledge base COMET, and infuse the knowledge using Gated Recurrent Units (GRUs) to explicitly model the mental states of the speaker. Then we propose a knowledge–aware mentalisation module based on dot-product attention to accordingly attend to the most relevant knowledge aspects. A supervised contrastive learning module is also utilised to fully leverage label information for capturing class-specific features. We test the proposed methods on a depression detection dataset Depression_Mixed with 3165 Reddit and blog posts, a stress detection dataset Dreaddit with 3553 Reddit posts, and a stress factors recognition dataset SAD with 6850 SMS-like messages. The experimental results show that our method achieves new state-of-the-art results on all datasets: 95.4% of F1 scores on Depression_Mixed, 83.5% on Dreaddit and 77.8% on SAD, with 2.07% average improvement. Factor-specific analysis and ablation study prove the effectiveness of all proposed modules, while UMAP analysis and case study visualise their mechanisms. We believe our work facilitates detection and analysis of depression and stress on social media data, and shows potential for applications on other mental health conditions.  相似文献

Understanding how brands should operate on social media is very important for contemporary marketing researchers and managers. This paper argues that due to the social and networked nature of social media it is an ideal environment for brand communities. Taking a deep qualitative approach and with analysis of a vast array of data, the article articulates the existence of brand communities on social media. More importantly, it delineates five unique and relevant dimensions of brand communities based in social media. The authors advise researchers to consider these dimensions while conducting research on brand communities and social media. Further implications for practitioners and researchers are discussed.  相似文献

Nowadays, it is a common practice for healthcare professionals to spread medical knowledge by posting health articles on social media. However, promoting users’ intention to share such articles is challenging because the extent of sharing intention varies in their eHealth literacy (high or low) and the content valence of the article that they are exposed to (positive or negative). This study investigates boundary conditions under which eHealth literacy and content valence help to increase users’ intention to share by introducing a moderating role of confirmation bias—a tendency to prefer information that conforms to their initial beliefs. A 2 (eHealth literacy: high vs. low) × 2 (content valence: positive vs. negative) between-subjects experiment was conducted in a sample of 80 participants. Levels of confirmation bias ranging from extreme negative bias to extreme positive bias among the participants were assessed during the experiment. Results suggested that: (1) users with a high level of eHealth literacy were more likely to share positive health articles when they had extreme confirmation bias; (2) users with a high level of eHealth literacy were more likely to share negative health articles when they had moderate confirmation bias or no confirmation bias; (3) users with a low level of eHealth literacy were more likely to share health articles regardless of positive or negative content valence when they had moderate positive confirmation bias. This study sheds new light on the role of confirmation bias in users’ health information sharing. Also, it offers implications for health information providers who want to increase the visibility of their online health articles: they need to consider readers’ eHealth literacy and confirmation bias when deciding the content valence of the articles.  相似文献

In this article we analyze 102 case studies of Internet or social media-enabled participatory projects, technologies, platforms and companies in operation between roughly 2005–2015. We assign each case a “signature” representing the degree of presence/absence of seven dimensions of participation and then cluster these signatures to look for patterns of the most common ways of “doing participation” today. Two main clusters become apparent: 1) a “radical-direct” mode that emphasizes direct individual autonomy and influence, commitment to having a voice and setting goals, and individual or collective control over resources thereby produced; and 2) an “experiential-affective” mode that emphasizes the experience of being or becoming part of a collective, and the affective, communicational, and educational features of that experience.  相似文献

This paper aims to contribute to the conceptual debate on the connection between social innovation and social entrepreneurship, considering the role of the ‘social’ within this connection. Supported by a systematic literature review (SLR) with an in-depth analysis of 34 articles from Scopus-indexed and Web of Science databases journals, this paper identifies, analyzes and describes the difficulties and opportunities in the social innovation and social entrepreneurship literature. Little is known about the link between both concepts and the influence of the ‘social’ in their development and implementation. This SLR was conducted to identify and describe definitions and patterns. Results show that the connection between social innovation and social entrepreneurship is in its take-off phase, but it still is a fragmented field with a huge lack of consensus. Thus, it will be important to see where the field will head, as this paper aims to be a first step in the understanding of social innovation and social entrepreneurship through a collective and integrated perspective, providing an elucidation of the different perspectives of the literature.  相似文献

This paper systematically examines (i) how individual personality can influence on cultural acculturation which can impact on the higher level of perceived value in LGBTs, and (ii) how the higher level of perceived value towards social media can result in being more satisfied, (iii) consequently having a better working life at workplace and performance proficiency. The generated framework was validated through a survey from multinational corporations in multi-industries such as higher education (with more than two campuses around the world), global fashion, global retailing, tourism, hospitality, food, and electronics and information technology. Key results, implications for managers and researchers are highlighted.  相似文献

The proliferation of social commerce has changed customers’ purchase decision-making process. However, few studies have investigated the roles of social commerce factors on customers’ purchase decision-making. Based on the social learning theory, we develop a research model to examine how customers’ learning behavior along three main social commerce components (SCCs) affects customers’ attitude in both cognitive and affective dimensions and how such attitude determines customers’ purchase intention. The results from a survey of 243 actual users of social commerce websites suggest that cognitive and affective appraisals are the main predictors of purchase intention, with cognitive appraisal having a higher predictive power than affective appraisal. In addition, learning from forums and communities and learning from ratings and reviews have significant influences on both cognitive and affective appraisals, while learning from forums and communities plays a more important role in formulating affective appraisal and learning from ratings and reviews plays a more important role in determining cognitive appraisal. Contrary to our expectation, learning from social recommendations has no significant influence on either cognitive or affective appraisal. In summary, these findings provide a comprehensive understanding about customers’ purchase decision-making process and extend the application scope of social learning theory. The findings also provide social commerce managers guidance in designing more effective websites and allocating resources and efforts reasonably on different SCCs.  相似文献

This multidimensional study looks at the influence of social capital and internal vs external locus of control on tacit knowledge-sharing intention and behaviour, and the relationship between the two. The relations studied within the framework of the proposed model are tested by regression analyses. The findings indicate that social capital and its basic structural, cognitive, and relational dimensions tend to increase tacit knowledge-sharing intention, which gradually turns into behaviour because, according to Ajzen’s theory of planned behaviour, behavioural intention is the immediate antecedent to behaviour (or according to Ajzen’s theory of planned behaviour, a person’s intention to perform a behaviour increases as subjective norms become more favourable). It is further concluded that having an internal locus of control increases both the intentions and behaviour, whereas external locus of control only increases the behaviour. The study also concludes that tacit knowledge-sharing intention gradually turns into sharing behaviour. The study is considered to contribute to the field of knowledge management in various ways. In this study a multidimensional survey of 42 questions was used to investigate the research topic and its sub-dimensions, and the data were collected via face-to-face interviews. The population of the study was 106 nursing students, and all components of the research universe were reached. It was found that social capital positively affects and increases tacit knowledge-sharing intentions and behaviour. A research model based on the conceptual framework was developed and research questions were addressed by means of this model and the findings.  相似文献

This paper investigates the rationale for choosing franchising rather than independent activity, arguing that this choice may be motivated by knowledge and competence considerations. We consider the franchise chain as a specific learning organizational form and explore whether this structure handles knowledge and builds competences according to an idiosyncratic pattern. Concretely, we empirically identify differences in the architecture of competences of franchised vs independent shops in the car maintenance industry in France, and analyse some causes for those differences. Thanks to in depth interviews coupled with lexical and quantitative analyses we find that franchised shops do master specific competences. However, the distinctive competences held by franchisees do not necessarily reflect franchisors’ knowledge, and are not exclusively the consequences of a shared identity in the franchise chain. We conclude that the development of franchise cannot be explained by competence-related arguments only, knowledge and competences being managed in distinctive ways within different franchising networks.  相似文献

This study aims to reveal the mechanism of how consumers’ engagement is established in social commerce communities. Building upon social support theory, we propose models and employ datasets obtained from Douban.com to empirically investigate the different effects of emotional and informational support on consumers’ engagement and how involvement mediates these relationships in the social commerce context. At the same time, the moderating role of product presentation is examined to help clarify the impact of social support and consumer involvement. Our analyses reveal that the two subdimensions of social supportive information are positively related to consumer involvement, together promoting consumers’ engagement in the community. In particular, involvement imposes a full mediating influence on emotional support but a partial mediating impact on informational support. Product presentation strengthens the effects in that the predictive effect of determinants on engagement is more pronounced for books with electronic versions in the social commerce community. For researchers and managers, these findings emphasize the benefits of the social commerce community, particularly with regard to Douban.com in China.  相似文献

People use social media to help them solve problems and enhance performance. Users may engage in diverse social interactions online, increasing their knowledge base through both weak and strong ties. In this study we investigate the impact of social networks on job performance, focusing on knowledge quality and diversity based on social network theory and the knowledge-based view. The empirical analysis reveals that the strength of social network ties is strongly associated with knowledge quality in offline interactions, while social network diversity is associated with knowledge quality in online interactions. Knowledge quality acquired from social network has a significant impact on both creativity and productivity of job performance in the workplace. However, knowledge diversity acquired from diverse social network interactions is strongly associated with creativity, but not with productivity. The results of this study increase our understanding of the knowledge sourcing behaviors of workers.  相似文献

The rise of social media has created a new e-commerce platform called social commerce. In social commerce, e-vendors such as Amazon may integrate social media with their traditional e-commerce sites. Based on self-determination theory and social commerce literature, we develop a model illustrating how social commerce features may impact consumer behaviors and facilitate social commerce benefits from the extrinsic motivation perspective. We identify four types of extrinsic motivation including external motivation, introjected motivation, identified motivation, and integrated motivation; and we examine their influences on consumers’ intention to contribute social commerce information, which in turn leads to their subsequent behaviors and increases the perceived benefit of social commerce. We also consider the moderating effect of gender in the formulation of social commerce benefits. Based on longitudinal survey data from Amazon consumers, we find that 1) consumers’ external and identified motivation has a positive impact on intention to contribute social commerce information; 2) consumers’ intention is positively associated with their future behaviors, which in turn facilitate their perceptions of social commerce benefits; and 3) gender moderates the impact of behavior on social commerce benefits.  相似文献
