the purpose of this article is to introduce the thoughts of pierre bourdieu, admittedly one of the greatest sociologists of the 20th century. his works, produced within the last three decades, go beyond conventional sociological research, making a fruitful theoretical contribution to sociology. his sociology is based on a basic idea: social reality lies neither on individuals nor on groups, but...

We explore how ideas from infectious disease and genetics can be used to uncover patterns of cultural inheritance and innovation in a corpus of 591 national constitutions spanning 1789–2008. Legal “ideas” are encoded as “topics”—words statistically linked in documents—derived from topic modeling the corpus of constitutions. Using these topics we derive a diffusion network for borrowing from anc...

1. Introduction Severe plastic deformation (SPD) is nowadays used to produce sizeable amounts of bulk nanocrystalline materials, which renders them suitable for different innovative applications, owing to favourable combinations of high mechanical strength and enhanced ductility they offer. Enhanced grain boundary diffusion is largely responsible for the resulting property combinations. SPD pro...

We introduce random directed acyclic graph and use it to model the information diffusion network. Subsequently, we analyze the cascade generation model (CGM) introduced by Leskovec et al. [19]. Until now only empirical studies of this model were done. In this paper, we present the first theoretical proof that the sizes of cascades generated by the CGM follow the power-law distribution, which is...

In the framework of heavy mid-level processing for high speed imaging, a nonlinear bi-dimensional network is proposed, allowing the implementation of active curve algorithms. Usually this efficient type of algorithm is prohibitive for real-time image processing due to its calculus charge and the inadequate structure for the use of serial or parallel architectures. Another kind of implementation...
