Applying Graph Theory to Conservation Documentation
… triangle count, motif frequency, diameter and eigenvector centrality measures were found to be diagnostic for comparing or contrasting data collection practices as evidenced in the datasets across institutions. Eigenvector centrality is also a strong candidate for systematic model validation …

A social networks framework to study the influence of language on international trade in services.
… I first estimate the linear effects of eigenvector centrality on per capita income, and then on exports. The results reveal that there is a positive relationship between linguistic influence and exports.

Social network analysis in college choice.
… taking Baylor University as a case study. Degree centrality and eigenvector centrality are two centrality measures used as interested independent variables. Findings reveal that peer groups have significant effects on college choice in terms of high school and home neighborhood networks. …

Evaluation of network inference algorithms and their effects on network analysis for the study of small metabolomic data sets
… studies), including betweenness, closeness, and eigenvector centrality were applied to simu- lated data. Differential network analysis was additionally applied to experimental AD data. Based on the performance measure benchmarking and network analysis results, I identified Probabilistic Context …

From the Streets to the Tweets: Social Network Analysis of Canadian Street Gang Members and Their Use of Twitter, Facebook and Youtube
… employed social network analysis to test whether centrality measures can extrapolate gang roles within a gang member’s Twitter network. Using content analysis, the results demonstrated that the most prominent type of cyber-banging is content that promotes gang ideologies. The results also conclude …

The Economics of Cryptocurrencies
… ad- dresses into ten deciles based on their centrality, we find that addresses in the two most-connected deciles earn higher returns than the other connected addresses. Third, eigenvector centrality is more related than degree centrality to higher returns, implying that quality of connections …

Leveraging Information Theory and Ecological Network Analysis to Monitor Communication Networks in a Student Aerospace Team
… Number of Links, Linkage Density, Betweenness, Eigenvector Centrality, and Total System Overhead (normalized) were consistent with other research and ecosystem literature, in that they presented values corresponding with a maturing ecosystem. This work provides a key first step towards a novel, …

Resource allocation and Uncertainties: An application case study of portfolio decision analysis and a numerical analysis on evidence theory
… Rank correlation, hierarchical clustering, and eigenvector centrality are used for comparison. The results obtained are discussed and com- mented on to gain a broader understanding of the behavior of the measures and the similarities and non-similarities between them.

Know your place - Social network analysis in cooperatively breeding white-winged choughs (Corcorax melanorhamphos)
… to all other individuals in the group (closeness centrality) and network connectedness (eigenvector centrality). I also identified social clusters. I then compared social networks between two stages of breeding, the nesting and post-fledging stages, to understand the impact of nesting activity on …

Essays On The Applications Of Network Analysis To The Reinsurance Market
… network position, measured by its network centrality, has economically significant implications for its loss experience and performance. Particularly, I find that there is an inverse U-shaped relationship between an insurer's network position and its combined ratio, and a U-shaped …

Resource Efficiency in the Chemical Industry
… Network metrics rank areas of the site with eigenvector centrality found to be the most relevant metric, but additional tailoring is required to make them applicable to an industrial setting. Industrial decision-makers at the level of the site can have immediate impact on reducing emissions …
