Core–periphery structures in national higher education systems. A cross-country analysis using interlinking data

This paper presents a comparative analysis of the structure of national higher education networks in six European countries using interlinking data. We show that national HE systems display a common core–periphery structure, which we explain by the lasting reputational differences in science, as well as the process of expansion and integration of HE systems. Furthermore, we demonstrate that centrality in national networks (coreness) is associated with organizational characteristics, reflecting that interlinking is motivated by access to resources and the status of the organizations concerned, and that national policies impact network structures by influencing the level of inequality in the distribution of resources and status. Finally, we show that, as an outcome of the core–periphery structure, the strength of ties between two HEIs is largely determined by their individual coreness, while the impact of distance is too small-scale to alter the network structure generated by organizational attributes.     

Mathematical properties of Q-measures

Q-measures are network indicators that gauge a node's brokerage role between different groups in the network. Previous studies have focused on their definition for different network types and their practical application. Little attention has, however, been paid to their theoretical and mathematical characterization. In this article we contribute to a better understanding of Q-measures by studying some of their mathematical properties in the context of unweighted, undirected networks. An external Q-measure complementing the previously defined local and global Q-measure is introduced. We prove a number of relations between the values of the global, the local and the external Q-measure and betweenness centrality, and show how the global Q-measure can be rewritten as a convex decomposition of the local and external Q-measures. Furthermore, we formally characterize when Q-measures obtain their maximal value. It turns out that this is only possible in a limited number of very specific circumstances.     

Target-driven reforms: Education for All and the translations of equity and inclusion in India

This paper critically examines the ways in which inclusion and equity are constituted through education development policies in India. Programmes implemented under global and national Education for All (EFA) policies have largely involved the quantification of ‘equity’ whereby schooling processes are measured against broad targets for school outcomes – focused mainly on student attendance, retention and academic achievement. Drawing on perspectives from Actor Network Theory, the paper puts forward the view of development reforms as ‘networks of translation’ in order to trace the shifts and vicissitudes of educational ideals. Reporting on ethnographic data of two reforms in the south Indian state of Karnataka, we show how narrow understandings of equity are produced through target-driven approaches to EFA. In doing so, the paper highlights the performative effects of education development policy and its potentially counterproductive consequences in contexts of poverty and marginalisation.     

Uncovering influence through Social Network Analysis: the role of schools in Education for Sustainable Development

Abstract

This paper examines the implementation of Education for Sustainable Development (ESD) in Germany and explores the possibilities of Social Network Analysis (SNA) for uncovering influential actors in educational policy innovation processes. From the theoretical perspective, an actor’s influence is inferred from its relative position within issue-specific information flows and the trust placed in its capacities and expertise, instead of relying on an actor’s openly expressed role and policy preferences. Drawing on techniques from quantitative SNA enables to analyse the social interactions as well as the frequency and type of information exchange amongst actors in a particular issue area. Empirically, I focus my attention on the educational innovation of ESD, which has been initiated at the global level, but is mainly put into practice at the national or regional level. Data for the study come from mixed mode interviews with a standardised questionnaire. The interviews were conducted and analysed using egocentric and complete SNA. I find, amongst others results, that NGOs and governmental actors occupy significantly more central, prestigious and influential network positions than schools in the course of implementing ESD in Germany. Furthermore, school representatives exhibit few and weak relations, and mostly share links with other formal education actors.
