Predictors of pro-environmental behavior of political actors and residents in small German towns
Understanding what drives pro-environmental behavior (PEB) in understudied settings such as the rural areas of industrialized nations is essential for advancing sustainable development and mitigating climate change. This study examined the effects of environmental concerns, feelings of cognitive dissonance and moral disengagement, as well as innovativeness and life satisfaction on PEB among 1646 public officials and citizens from small German mun…

Natural or intended mummification? Specific case of a child mummy
The aim of this work was to document and analyze an exceptionally preserved mummified body of a six-year-old boy found in a family tomb in Skalná, Czech Republic. The boy died of scarlet fever in 1887, and was buried under ground in a cemetery in an unknown coffin shortly after death. His parents exhumed his cadaver and entombed it in the family crypt in two tin coffins a year later. This secondary burial and violent opening of the coffins in the…

National and international interlocking directorates within Europe: Corporate networks within and among fifteen European countries
This article focuses on the structural aspects of interlocking directorate networks within and among fifteen European countries. The results show large quantitative differences in network densities within countries. These differences are strongly and significantly related to the 'variety of capitalism' in place. Second, an analysis of the interlocking directorates across country borders reveals a European interlocking directorate network in which…
Distinctive Roles of Lead Users and Opinion Leaders in the Social Networks of Schoolchildren
Prior research has shown that both lead users and opinion leaders may propel the diffusion of innovation. This raises the question of whether lead users and opinion leaders are positioned similarly in social networks, which we address using a sample of 23 school classes consisting of 537 children. Research among children is very scarce in this particular domain. Our statistical analyses based on hierarchical linear modeling reveal two general res…
Standardizing the Segmentation Index S 3
The segmentation index S 3 of Baerveldt and Snijders (1994) Baerveldt, C. and Snijders, T. 1994. Influences on and from the segmentation of networks: Hypotheses and tests. Social Networks, 16: 213–232. [Crossref], [Web of Science ®] , [Google Scholar] is used in the research of social cohesion. However, as is often the case with network level measures, the index is sensitive to network size and density. Therefore, networks of different size or de…
