This problem set is designed to give you an overview of the portions of the UCINET software that are particularly useful for studying two-mode or “affiliation” network data. Two mode data has driven some of the most comprehensive data analyses done to date in network analysis, including Laumann and Knoke’s The Organizational State. UCINET has several routines built into it to analyze this type ...

Informationsnetzwerke sind wesentliche Komponenten von Unternehmen, Angebotsketten und Märkten. Für die Darstellung und Analyse von Informationsnetzwerken gibt es eine Vielzahl von Softwareprogrammen mit unterschiedlichem Leistungsumfang. Im Folgenden werden die Softwareprogramme identifiziert, auf Grundlage einer Auswahl von Leistungsmerkmalen miteinander verglichen und mit Hilfe des AHP beurt...

An algorithm is proposed to detect community structures in social networks. The algorithm begins with a community division based on prior knowledge of the degrees of the nodes and then combines the communities until a clear partition is obtained. In applications such as a computer-generated network, Ucinet networks, and Chinese rural-urban migrants’ social networks, the algorithm can achieve hi...

A Weighted Relational Classification Algorithm Based on Rough Set is proposed in this paper. The relations of tables are classified in database, relational graph is converted into 0 1 matrix, the weight is calculated using UCINET; at the same time, different condition attributes are weighted differently by using attribute frequency of Rough Set. It is improved effectively. Experiments have prov...

During the first years of 21st century, political, economic, and institutional crisis in Argentina, linked to fall convertibility plan; led strengthening associative, collaborative, community livelihoods (Hintze, 2003; Palomino, 2005; Pastore, 2010). In dialogue with this situation, from field visual arts, Venus Project arises, a network artists created Buenos Aires, Argentina. Venus, operated ...

This paper surveys the range of techniques available for the analysis of 2-mode (actor-byevent) datasets and proposes an additional option for visualization and analysis that uses the linegraph of the bipartite adjacency matrix. The nodes of this line-graph are roles or statuses conferred on actors through their participation in events or recognition of their group membership. The line-graph ca...

The core/periphery structure is ubiquitous in network studies. The discrete version of the concept is that individuals in a group belong to either the core, which has a high density of ties, or to the periphery, which has a low density of ties. The density of ties between the core and the periphery may be either high or low. If the core/periphery structure is given a priori, then there is no pr...

Aim: To determine the out degree centrality for multivariate analysis, examine the demographic differences and characteristics of callers who make more calls, and determine callers who are more likely to make at least one positive Ebola call. Methods: Surveillance data for 393 suspected Ebola cases (192 males, 201 females) were collected from October 23, 2014 to June 28, 2015 using cell phone t...
