ABSTRACT Complex systems are often characterized by large-scale hierarchical organizations. Whether the prominent elements, at the top of the hierarchy, share and control resources or avoid one another lies at the heart of a system's global organization and functioning. Inspired by network perspectives, we propose a new general framework for studying the tendency of prominent elements to form clubs with exclusive control over the majority of a system's resources. We explore associations between prominence and control in the fields of transportation, scientific collaboration, and online communication.

    ABSTRACT: Despite voluminous literature explaining the emergence and the electoral contours of right wing radicalism in Europe, little is known about the location of radical right mass communication channels in the media sphere. The aim of this article is to fill the gap by identifying and analysing the positions of the radical right media within the network structure of the general media sphere. To do so, Hungary is an excellent illustrative case as a country in which the radical right wing Jobbik party won 21 percent of the votes in the 2014 parliamentary election that cemented its status as by far the largest radical right group in Central Europe. We provide an issue-centred approach in which the media networks of two of the most controversial political topics of the year 2014 in Hungarian politics are explored. To compose the networks, we concentrate on the interaction ties that are defined here as direct, and explicit citations or hyperlinks to the content of other media products. The empirical test of ideal typical networks reveals that the radical right products stay under the radar of the mainstream media. It is our finding that the representatives of the radical media remain on the fringe of the media sphere in Hungary.

    ABSTRACT: This paper aims to contribute to the growing body of literature that investigates the polarization of the Hungarian politics. Based on previous reflections on the heavily partisan, increasingly post-objective and highly fragmented nature of the Hungarian media, we provide an issue-centred case study approach to comprehend whether mass communication integrate or divide us 25 years after the collapse of the communist regime. For an empirical test of polarization, we explore the media networks of one of the most covered issues of 2014 General Election Campaign in Hungary. To link a medium to another one, we concentrate on interactions, which are defined here as direct, and explicit citations or hyperlinks to the content of other media products and communication of politicians. Our research supports the moderate version of political polarization in media sphere. Findings indicate that the media outlets intensively connect to each other regardless of their ideological preferences. The study however reveals proof of the slightly polarised media sphere after having analysed the patterns of connections between the media and political actors. It is our conclusion that the Hungarian media are far from being politically hyperpolarised. Ideologically oriented blocs are discovered, still there are intensive interactions between the media outlets having different political colours. Media therefore demonstrate the capacity to overcome partisan animosity and integrate the politically divided Hungarian society.

    ABSTRACT: Neurodevelopmental benefits of increased gestation have not been fully characterized in terms of network organization. Since brain function can be understood as an integrated network of neural information from distributed brain regions, investigation of the effects of gestational length on network properties is a critical goal of human developmental neuroscience. Using diffusion tensor imaging and fiber tractography, we investigated the effects of gestational length on the small-world attributes and rich club organization of 147 preadolescent children, whose gestational length ranged from 29 to 42weeks. Higher network efficiency was positively associated with longer gestation. The longer gestation was correlated with increased local efficiency in the posterior medial cortex, including the precuneus, cuneus, and superior parietal regions. Rich club organization was also observed indicating the existence of highly interconnected structural hubs formed in preadolescent children. Connectivity among rich club members and from rich club regions was positively associated with the length of gestation, indicating the higher level of topological benefits of structural connectivity from longer gestation in the predominant regions of brain networks. The findings provide evidence that longer gestation is associated with improved topological organization of the preadolescent brain, characterized by the increased communication capacity of the brain network and enhanced directional strength of brain connectivity with central hub regions.
