Social Network Analysis (SNA) is an emerging research field in finance, above all in Brazil. This work is pioneering in that it is supported by reference to different areas of knowledge: social network analysis and corporate governance, for dealing with a similarly emerging topic in finance; interlocking boards, the purpose being to check the validity of the small-world model in the Brazilian capital market, and the existence of associations between the positioning of the firm in the network of corporate relationships and its worth. To do so official data relating to more than 400 companies listed in Brazil between 1997 and 2007 were used. The main results obtained suggest that the configuration of the networks of relationships between board members and companies reflects the small-world model. Furthermore, there seems to be a significant relationship between the firm’s centrality and its worth, described according to an “inverted U” curve, which suggests the existence of optimum values of social prominence in the corporate network.

In this paper we provide some insights in Homer's Iliad from the perspective of social network analysis. We use the original text and other public available data to create a social network (i.e. a graph) that comprises of all actors in the Iliad together with their interactions. We present some visualizations of these data and discuss concepts like connectivity, connected components and groupings. Furthermore, we calculate some well-established metrics, coming from social network analysis in this social network and discuss the numerical results. These results indicate that the Iliadic network is a small-world network, rather dissasortative and relatively easy to disconnect.

Soccer is the most popular sport in the world and due its popularity, soccer moves billions of euros over the years, in most diverse forms, such as marketing, merchandising, TV quotas and players transfers. As example, in the 2016/2017 season, only England has moved about 1.3 billion of euros only in players transfers. In this work, it is performed a study of the transfer market of player. To do so, players transfer data were gathered from the website Transfermarkt and were modeled as a graph. In order to perform this study, different Complex Networks techniques were applied, such as Overlap Community Detection and Property Analysis. Through our results we could evaluate the soccer players market, and see a pattern that every market has at least one farm country, which has a main function of selling athletes, or a buyer country, which most of its transactions is buying players.

Data protection and data-driven solutions are two progressing areas permeating Brazilian society. This work presents an interdisciplinary theoretical approach related to Ethics, from the ethics in computing perspective; the LGPD, from the Law studies perspective; and the Social Network Analysis in Brazil, from the Informatics perspective. This research area utilizes personal data extensively for knowledge construction, with semantic contributions, analyzing the reality; or pragmatic, building artifacts. Challenges and inseparable issues are observed, exposed, and debated in this work. We present considerations combining the three topics, personal data in the research field of social networks in Brazil respecting the LGPD and ethics precepts.

Purpose – This paper aims to explore the characteristics of the co-occurrence network of online tags and propose new approaches of applying social network analysis by utilising social tagging in order to organise data. Design/methodology/approach – The authors collected online resources labelled “tag” from 7 November 2004 to 31 October 2011 from the CiteULike website, comprising 684 papers and their URLs, titles and data on tagging (users, times, and tags). They examined the co-occurrence network of online tags by using the analyses of social networks, including the analysis of coherence, the analysis of centricity and core to periphery categorical analysis. Findings – Some features of the co-occurrence of online tags are as follows: the internet is subject to the “small world” phenomenon, as well as being “scale-free”. The structure of the internet reflects stable areas of core knowledge. In addition to five possible applications of social network analysis, social tagging has the greatest significance in organising online resources. Originality/value – This research finds that co-occurrence of tags online is an effective way to organise and index data. Some suggestions are provided on the organisation of online resources.

Cities are formalising collaborations across borders at an unprecedented rate: ‘city networks’ now form a wide ecosystem of global partnerships between local authorities that is often underestimated. It might be time to think of city networks more explicitly as institutionalised and presenting a challenging form of more-than-local urban governance. To do so, our essay mixes a review of the overall global landscape (beyond the environmental sector where most of the literature is to be found), with both a network analysis of how these institutions work as a web of connections, as well as an ‘inside out’ view of how they are managed and what the challenges of that are. We do this by analysing a database of 202 of these networks, both statistically as well as via social network analysis. We find that: international initiatives are on the rise, but this context of partnerships has a well-established history, producing a wealth of information and outputs and offering a complex organisational landscape for cities to reach out beyond their local confines. We measure the relationship this has to the integration of cities into the global economy, the pathways it opens for further internationalisation of city leadership and the patterns of partnership with business and international organisations that it implies.
