“…Typically, the static analysis of a network includes -but is not limited to-: the application of different tools aimed at determining the importance of nodes under different prisms or measures of centrality (Landherr, Friedl & Heidemann 2010); the identification of the general patterns of the network as a whole -how the network links are distributed, how easy it is to navigate from one point to another, how dense the network is, what is the probability of closed triangles, etc. -which, in many cases, determine its functioning (Newman 2003a); and/or the analysis of the mesoscale behavior of the network, that is, of the intermediate levels between the node and the network as a whole, which can provide relevant information about the network; remarkably, community detection algorithms are among the most important mesoscale analysis tools (Bedi & Sharma 2016;Fortunato & Hric 2016;Fortunato & Newman 2022).…”

Este artículo analiza la base de datos TESEO mediante redes complejas para obtener la estructura informal del área de conocimiento de Organización de Empresas en España. Para ello, toma todas las tesis referidas al campo UNESCO de Organización y Dirección de Empresas, y las analiza de forma estática. Los resultados revelan una distribución de grado de la participación en tribunales y supervisión de tesis compatible con una ley de potencia truncada, y una clara estructura modular. Los patrones encontrados analizando el núcleo de la red pueden ser parcialmente explicados por homofilia entre los investigadores de la misma asociación académica.

Effective linkages among farmers play a crucial role in fostering growth within the agriculture sector. This study conducted during 2020-23 utilizes social network analysis to examine the backward and forward agribusiness linkages of farmers in Dairy Farmer Producer Organizations (FPOs) in Madhya Pradesh and Bihar. Through focused group discussions, a comprehensive list of private and government institutions acting as linkage actors for each FPO were compiled. The findings highlight that farmers primarily rely on strong informal ties for accessing agricultural information and services. Furthermore, a disparity is observed between the FPOs in Bihar and Madhya Pradesh, with the former having a smaller number of linkage actors. The FPO in Bihar demonstrates stronger associations with government institutions and officials, while the FPO in Madhya Pradesh exhibits stronger connections with private entities, including the food processing industry, artificial insemination (AI) technicians, and veterinary doctors. The study provides valuable insights into the connectedness of network actors, underscores the importance of multi-actor alliances, and emphasizes the implications of centrality measures in determining network dynamics.

“…The definition of node importance and, hence, its centrality depends on the type of network being examined and the object of study. For example, in a social network, nodes that communicate with a large number of others, that is, nodes with a large number of links to other nodes (which may correspond to a large number of friendship relationships), are considered important [17]. Conversely, in an information flow network, a large number of links of a node does not necessarily make it important, as, for example, control over the information flowing between nodes is prioritized [18].…”

Transportation Networks in the Face of Climate Change Adaptation: A Review of Centrality Measures

This paper presents a comprehensive review of centrality measures and their usefulness in transportation networks in the face of climate change adaptation. The focus is on understanding the importance of transportation nodes in the event of extreme weather events and climate-related disasters that may render them inoperable. The paper argues that if critical nodes can be identified, they can be better protected, while resources can be allocated to ensure their functioning in the event of such events. The paper assesses 17 centrality measures, including degree, closeness, betweenness, eigenvector, and Katz, and evaluates their usefulness and usability in transportation networks. The review highlights the need to reformulate these measures to take into account traffic- and transport-related parameters and variables. Without this reformulation, centrality measures only reveal node importance in a topological or structural way and fail to capture the true significance of the nodes in a transportation network. The reformulation enables the centrality measures to be properly applied in a transportation network and to expose the significance of their elements. This work has important implications for transportation planners and policy-makers in ensuring the resilience of critical transportation infrastructure in the face of climate-related disasters.
