Gender and researchers with institutional affiliations in the global south/north in social network science

Applied Network Science, 2022
The following article aims to understand the prevalence of ascribed social characteristics such as the role of gender and the country of institutional affiliation of the authors in two prominent journals of social network science. Accordingly, we explore

Social inertia in collaboration networks [PDF]

, 2005
This work is a study of the properties of collaboration networks employing the formalism of weighted graphs to represent their one-mode projection. The weight of the edges is directly the number of times that a partnership has been repeated.

Inequality is rising where social network segregation interacts with urban topology

Nature Communications, 2021
Not much is known about the joint relationships between social network structure, urban geography, and inequality. Here, the authors analyze an online social network and find that the fragmentation of social networks is significantly higher in towns in ...

Testing Schwartz’s Model of Cultural Value Orientations in Europe with the European Social Survey: An Empirical Comparison of Additive Indexes with Factor Scores

Survey Research Methods, 2023
Schwartz (2004) proposed a theory of seven cultural value orientations, ordered in a circle, that form three cultural value dimensions, hierarchy vs. egalitarianism, mastery vs. harmony, and autonomy vs.

Multiple phenotypic traits as triggers of host attacks towards ant symbionts: body size, morphological gestalt, and chemical mimicry accuracy

Frontiers in Zoology, 2021
Background Ant colonies are plagued by a diversity of arthropod guests, which adopt various strategies to avoid or to withstand host attacks. Chemical mimicry of host recognition cues is, for example, a common integration strategy of ant guests.

Chemical and behavioral integration of army ant-associated rove beetles – a comparison between specialists and generalists

Frontiers in Zoology, 2018
Host-symbiont interactions are embedded in ecological communities and range from unspecific to highly specific relationships. Army ants and their arthropod guests represent a fascinating example of species-rich host-symbiont associations where host ...
