On the discovery of social roles in large scale social systems

The social role of a participant in a social system is a label conceptualizing the circumstances under which she interacts within it. They may be used as a theoretical tool that explains why and how users participate in an online social system. Social role analysis also serves practical purposes, such as reducing the structure of complex systems to rela- tionships among roles rather than alters, and enabling a comparison of social systems that emerge in similar contexts. This article presents a data-driven approach for the discovery of social roles in large scale social systems. Motivated by an analysis of the present art, the method discovers roles by the conditional triad censuses of user ego-networks, which is a promising tool because they capture the degree to which basic social forces push upon a user to interact with others. Clusters of censuses, inferred from samples of large scale network carefully chosen to preserve local structural prop- erties, define the social roles. The promise of the method is demonstrated by discussing and discovering the roles that emerge in both Facebook and Wikipedia. The article con- cludes with a discussion of the challenges and future opportunities in the discovery of social roles in large social systems

Report on the theoretical framework and empirical toolkit for analysing literacy case-studies

In this report, we present a theoretical framework for the analysis and assessment of literacy practices and (socio)cultural participation (see section 1). In addition to this theoretical framework, we also present and evaluate a set of methodological tools. In order to evaluate this toolkit, C&E discusses the application of these methods for data collection and analysis, as well as their theoretical grounding (see section 2). Based on a case study of the developers’ discourse on social media platforms, we present part of the outcome generated with the methodological tools (see section 3). In the closing section of this report, we provide an overview of the affordances and limitations of the toolkit and briefly discuss how these issues will be addressed in the case studies that are now in progress.

Collaborative yet independent: Information practices in the physical sciences

In many ways, the physical sciences are at the forefront of using digital tools and methods to work with information and data. However, the fields and disciplines that make up the physical sciences are by no means uniform, and physical scientists find, use, and disseminate information in a variety of ways. This report examines information practices in the physical sciences across seven cases, and demonstrates the richly varied ways in which physical scientists work, collaborate, and share information and data. This report details seven case studies in the physical sciences. For each case, qualitative interviews and focus groups were used to understand the domain. Quantitative data gathered from a survey of participants highlights different information strategies employed across the cases, and identifies important software used for research. Finally, conclusions from across the cases are drawn, and recommendations are made. This report is the third in a series commissioned by the Research Information Network (RIN), each looking at information practices in a specific domain (life sciences, humanities, and physical sciences). The aim is to understand how researchers within a range of disciplines find and use information, and in particular how that has changed with the introduction of new technologies

Social media as a data gathering tool for international business qualitative research: opportunities and challenges

Lusophone African (LA) multinational enterprises (MNEs) are becoming a significant pan-African and global economic force regarding their international presence and influence. However, given the extreme poverty and lack of development in their home markets, many LA enterprises seeking to internationalize lack resources and legitimacy in international markets. Compared to higher income emerging markets, Lusophone enterprises in Africa face more significant challenges in their internationalization efforts. Concomitantly, conducting significant international business (IB) research in these markets to understand these MNEs internationalization strategies can be a very daunting task. The fast-growing rise of social media on the Internet, however, provides an opportunity for IB researchers to examine new phenomena in these markets in innovative ways. Unfortunately, for various reasons, qualitative researchers in IB have not fully embraced this opportunity. This article studies the use of social media in qualitative research in the field of IB. It offers an illustrative case based on qualitative research on internationalization modes of LAMNEs conducted by the authors in Angola and Mozambique using social media to identify and qualify the population sample, as well as interact with subjects and collect data. It discusses some of the challenges of using social media in those regions of Africa and suggests how scholars can design their studies to capitalize on social media and corresponding data as a tool for qualitative research. This article underscores the potential opportunities and challenges inherent in the use of social media in IB-oriented qualitative research, providing recommendations on how qualitative IB researchers can design their studies to capitalize on data generated by social media.https://doi.org/10.1080/15475778.2019.1634406https://doi.org/10.1080/15475778.2019.1634406https://doi.org/10.1080/15475778.2019.1634406https://doi.org/10.1080/15475778.2019.1634406Accepted manuscriptPublished versio

New Ways of Addressing the Psychological Traumas of War: Supplementing Traditional Social Supports to Prevent Homelessness Among Mentally Ill Veterans

Both nationally and in Rhode Island, there is a high prevalence of veterans in the homeless population. Many homeless veterans suffer from serious mental health issues and military specific traumas, adding to the social stigma they face. To avoid homelessness, veterans need to treat their mental illness with the assistance of their social support networks. Despite incredible advances in technology and mental health care, provision of mental health services to veterans still remains very traditional. With an influx of veterans returning from the current conflicts in Iraq and Afghanistan, a greater number of younger clients will be entering the system. Because of their comfort with computers, the Internet and social networking tools, there is a natural progression for these veterans to use the Internet to support one another in their return from combat and readjustment to civilian life. To prevent isolation and encourage continued receipt of mental health services, online social support services can help veterans avoid homelessness when used as a supplement to traditional mental health treatment. A survey of nine (N=9) social workers at the VAMC showed that social workers who serve veterans would find online social supports helpful for their clients and would recommend these services as a supplement to their traditional therapeutic treatment
