Research and Science Today Journal is a publication founded in 2011 and it is dedicated to the students of all levels (license, master and doctoral) of faculties in the country and abroad. We want to offer the participants the opportunity to present their scientific works in the following areas:...

A substantial number of studies have extended the work on universal properties in physical systems to complex networks in social, biological, and technological systems. In this paper, we present a complex networks perspective on interfirm organizational networks by mapping, analyzing and...

We propose an intuitive way of how to measure segregation in social and spatial networks. Using random walks, we define the segregation index as the probability that an individual meets an individual from the same social group. The segregation index is a generalization of the isolation index and...

The main contribution of this paper to current philosophical and sociological studies on modelling is to analyse modelling as an object-oriented interdisciplinary activity and thus to bring new insights into the wide, heterogeneous discourse on tools, forms and organisation of interdisciplinary...

This paper presents interesting correlations which exist between a model of long-wave economic activity and crisis in the United States – “the Political Economy wave” – and the structure of the rings of Saturn, one of the most confounding structures known to science. At the present time...

Gender differences are often observed in real life-situations. We implement an experiment on the investment game which explores the influence of knowledge of partner's gender in trust and reciprocity by means of two treatments of information: the first one, without knowledge of partner's gender...

This paper develops a measure of segregation based on two premises: (1) a measure of segregation should disaggregate to the level of individuals, and (2) an individual is more segregated the more segregated are the agents with whom she interacts. Developing three desirable axioms that any...

I explore the equilibrium value implications of economic models that incorporate reactions to a stochastic environment. I propose a dynamic value decomposition (DVD) designed to distinguish components of an underlying economic model that influence values over long horizons from components that...

In this paper, the relevance of national accounts statistics and their underlying conceptual framework is investigated for their four roles: description and object of analysis, tool for analysis and forecasting, tool for communication and decision-making and input for alternative accounts...

This paper derives several identities for the iterated integrals of a general semimartingale. They involve powers, brackets, exponential and the stochastic exponential. Their form and derivations are combinatorial. The formulae simplify for continuous or finite-variation semimartingales,...
