Recommendation approaches generally fail to recommend newly-published papers as relevant, owing to the lack of prior information about the said papers and, more particularly, problems associated with cold starts. It would appear, to all intents and purposes, that researchers currently interact more on social networks than they normally would in academic circles, and relationships of a purely academic nature have witnessed a paradigm shift, in keeping with this new trend. In existing paper recommendation methods, the social interaction factor has yet to play a pivotal role. The authors propose a social network-based research paper recommendation method, that alleviates cold start problems by incorporating users' social interaction, as well as topical relevancy, among assorted papers in the Mendeley academic social network using a novel approach, random walk Ergodic Markov Chain. The system yields improved results after cold start alleviation, compared with the existing system.

For years, achievements and discoveries made by researcher are made aware through research papers published in appropriate journals or conferences. Many a time, established s researcher and mainly new user are caught up in the predicament of choosing an appropriate conference to get their work all the time. Every scienti?c conference and journal is inclined towards a particular ?eld of research and there is a extensive group of them for any particular ?eld. Choosing an appropriate venue is needed as it helps in reaching out to the right listener and also to further one’s chance of getting their paper published. In this work, we address the problem of recommending appropriate conferences to the authors to increase their chances of receipt. We present three di?erent approaches for the same involving the use of social network of the authors and the content of the paper in the settings of dimensionality reduction and topic modelling. In all these approaches, we apply Correspondence Analysis (CA) to obtain appropriate relationships between the entities in question, such as conferences and papers. Our models show hopeful results when compared with existing methods such as content-based ?ltering, collaborative ?ltering and hybrid ?ltering.

Using survey data from an online Spanish university, real and perceived financial literacy levels, social interactions and personal trust with the social network are measured as key elements for collaborative finance development. This is the first study regarding the factors that may affect the use of collaborative finance. Results show levels of financial literacy are quiet low as in prior studies and individuals consider that the bank manager, friends, and parents can manage financial issues better than them, with the last two peers being those who most trust to discuss financial issues. The findings also provide information about how little individuals trust online networks when it comes to financial matters. Besides, respondents interact moderately with their social network missing the benefits of peer-to-peer learning. Overall, lack of financial literacy, low social interaction, and personal trust may be affecting the short use of collaborative financial services.

The article discusses the features of modern digital communication, which the author understands as social interaction of communicants aimed at informing the addressee and influencing him/her. Digital media genres have a set of features that allow them to be distinguished from many other media genres (intertextuality, hypertextuality, creolization). Competing with each other, the creators of digital texts try to make their texts more vivid, interesting, and memorable. It is for this purpose that many of them turn to such a phenomenon as outrage. After analyzing the texts of digital media (tweet reports, instagram texts and texts posted on the social network Facebook), the author concludes about the ways to create epatage at the lexical level. They included the use of reduced vocabulary, the use of words in a figurative meaning that is not fixed by explanatory dictionaries, the use of occasional and emotive vocabulary.

This chapter analyzes the optimal use of social networks by firms that wish to diffuse new products, rely on word-of-mouth communication for advertising, or exploit consumption externalities among consumers. It focuses on two topics: the targeting of individuals to diffuse information or opinions in a social network, and the pricing at different nodes of the social network when agents experience consumption externalities. In both cases, firms take the network of social interaction as given and consider how to optimally leverage social effects to introduce new products or maximize profits .

OBJECTIVE: The aim of the study was to compare users of community-based mental health day centres (DCs) and clubhouses in Sweden regarding reported social networks and social interaction and the stability of these over time. A further aim was to investigate social network predictors both cross-sectionally and longitudinally.METHODS: People regularly attending DCs (n=128) or clubhouses (n=57) completed questionnaires about social network and social interaction (social engagement and social functioning), self-esteem and socio-demographics at baseline and a nine-month follow-up. RESULTS: Perceived social engagement and social functioning did not differ between the groups and remained stable over time. Fewer in the DC reported having a close friend but there was no difference regarding having recently (the past week) seen a friend. When naming “someone with whom you can share your innermost thoughts and feelings”, the DC group named more professional contacts, fewer friends and more often “nobody” compared to the clubhouse group. Finally, on both occasions the DC group scored significantly lower on size of the social network compared to the clubhouse users. Self-esteem and having recently seen a friend could predict size of the social network in the cross-sectional perspective. Strong indicators of belonging to the group with a larger social network at follow-up were being a woman, attending a clubhouse programme and having scored high on social network at baseline.CONCLUSION & IMPLICATION FOR PRACTICE: Having friends and strengthening one’s self-esteem may be essential factors for the social network of people with psychiatric disabilities in a short-term perspective. Visiting clubhouses seems advantageous in a longer-term perspective.

In the last decade, there has been a great deal of interest in language MOOCs (LMOOCs) and their potential to offer learning opportunities for large audiences, including those in disadvantaged communities. However, experiences and research have shown MOOCs to suffer from several challenges. Chief among these have been low participation and completion rates, which are often attributed to limitations in how opportunities for personalisation and social interaction are implemented. For the current study, a dedicated LMOOC was designed and implemented, called the “Social and Personal Online Language Course (SPOLC).” This language learning environment incorporates a recommendation system and emphasizes personalisation and social interaction. The study identified the types of learning behaviour that were related to course completion and observed how 270 learners in the LMOOC used the various course features. The data were collected using learning analytical methods and analysed using binary logistic regression and feature extraction prediction model. The results demonstrated that working in groups and creating a learning plan were important factors associated with course completion, while interacting with other learners online was not. We conclude with several suggestions and implications for future LMOOC design, implementation, and research.

As a test of the social support hypothesis, highly anxious primiparous mothers were assigned in the post-natal stage to either a professional intervention, a lay intervention or to a control group. It was hypothesised that those receiving an active intervention (be it lay or professional assistance) would become less anxious as a consequence of a central therapeutic ingredient – social support. Improvement was assessed by measuring state anxiety levels at baseline and at 12 months, while the degree to which therapists were incorporated into the social network was assessed by the Interview Schedule for Social Interaction (ISSI), given at baseline and at 12 months. While we established that anxiety levels were significantly lowered in those receiving the professional intervention and moderately (but not significantly) lowered in those receiving the lay intervention, ISSI scores for the separate groups appeared stable over the study. Reasons are considered why ISSI scores remained unchanged while intervention groups showed a reduction in anxiety levels.
