Background: Information access is essential for quality healthcare provision and education. Despite technological advances, access to prosthetics and orthotics information in low- and middle-income countries is not ubiquitous. The current state of information access, availability, and exchange among prosthetics and orthotics faculty is unknown. Objectives: Describe information exchange networks and access at two prosthetics and orthotics programs in Ghana and the United States. Study design: Cross-sectional survey, social network analysis. Methods: An online survey of faculty at two prosthetics and orthotics programs using REDCap. The survey included a social network analysis, demographics, and prosthetics and orthotics information resources and frequency of use. Descriptive statistics were calculated. Results: Twenty-one faculty members completed the survey (84% response). Ghanaian faculty were on average younger (median Ghana: 27 years, United States: 43 years), had less teaching experience, and had less education than US faculty. Textbooks were the most commonly used resource at both programs. The Ghanaian network had more internal connections with few outside sources. The US network had fewer internal connections, relied heavily upon four key players, and had numerous outside contacts. Conclusion: Ghana and US faculty have two distinct information exchange networks. These networks identify key players and barriers to dissemination among faculty to promote successful knowledge translation of current scientific literature and technology development. Social network analysis may be a useful method to explore information sharing among prosthetics and orthotics faculty, and identify areas for further study.

Abstract The aim of this study was to characterize handball from a social network analysis perspective by analyzing 22 professional matches from the 2018 European Men's Handball Championship. Social network analysis has proven successful in the study of sports dynamics to investigate the interaction patterns of sport teams and the individual involvement of players. In handball, passing is crucial to establish an optimal position for throwing the ball into the goal of the opponent team. Moreover, different tactical formations are played during a game, often induced by two-minute suspensions or the addition of an offensive player replacing the goalkeeper as allowed by the International Handball Federation since 2016. Therefore, studying the interaction patterns of handball teams considering the different playing positions under various attack formations contributes to the tactical understanding of the sport. Degree and flow centrality as well as density and centralization values were computed. As a result, quantification of the contribution of individual players to the overall organization was achieved alongside the general balance in interplay. We identified the backcourt as the key players to structure interplay across tactical formations. While attack units without a goalkeeper were played longer, they were either more intensively structured around back positions (7 vs. 6) or spread out (5 + 1 vs. 6). We also found significant differences in the involvement of wing players across formations. The additional pivot in the 7 vs. 6 formation was mostly used to create space for back players and was less involved in interplay. Social network analysis turned out as a suitable method to govern and quantify team dynamics in handball.

Using Data

Terrorist Activities worldwide has led to the development of sophisticated methodologies for analyzing terrorist groups and networks. Ongoing and past research has found that Social Network Analysis (SNA) is most effective method for predictive counter-terrorism. Social Network Analysis (SNA) is an approach towards analyzing the terrorist networks to better understand the underlying structure of a network and to detect key players within the network and their links throughout the network. It is also need of the hour to convert available raw data into valuable information for the purpose of global security. Comparative study among SNA tools testify their applicability and usefulness for data gathered through online and offline social sources. However it is advised to incorporate temporal analysis using data mining methods, to improve the capability of SNA tools to handle dynamic social media data. This paper examine various aspects of Social Network Analysis as applied to terrorism, taking empirical data, and open source data based studies into account. This work primarily focuses on different types of decentralized terrorist networks and nodes. The nodes can be classified as organizations, places or persons. We take help of varied centrality measures to identify key players in this network.

This research provides an analysis of the Rooftop Urban Agriculture (RUA) community in Toronto by taking an inventory of participants and key players, and illustrating the communication network surrounding this emerging community. A social network assessment is used to reveal network connections, and explore the level of cohesion of the RUA community in Toronto. Consideration is given to the implications that this has on its growth, representation, and potential areas of engagement with other factors, including municipal decision makers. Semi structured interviews reveal the driving values expressed by RUA practitioners and others involved with the practice, and the characteristics of this group’s formation. Based on this information, RUA is identified in this work as an emerging Civic Food Network(CFN). Based on the findings of the network assessment, this research argues that the lack of an organized and cohesive RUA Network is hindering the progress of this emerging group, and the potential for valuable knowledge sharing that would enable its growth. Finally, recommendations are provided to address how those practicing rooftop agriculture can seek to maximize knowledge sharing within the RUA community and build connections to the City of Toronto to strengthen this emerging CFN.

The rise of social media had opened up an easy and fast way to distribute pornographic content through it. Although the negative effects linked to porn consumption are still inconclusive, government had established regulation regarding porn creation, distribution, and ownership. Unfortunately, the regulation is not well run. Porn are freely distributed through social media without any reaction from the authorities. This reseach aims to understand the distribution pattern and to find key players in the distribution of porn in social media using Social Network Analysis (SNA) so that mitigative actions could be made. Result shows that porn were first published by popular ‘Publisher’ accounts, re-shared by other publisher accounts or ‘Retweeters’, and unidirectionally consumed by followers (‘Consumers’). Interpretation and research limitations were discussed.
