This paper describes a computational model of time allocation in a social network. It particularly focuses on the impact of inequalities or so called stratification process on the efficiency of resources allocation. The presented model is a multi-agent system with implemented network evolution mechanism. The stratification is modeled by the order in which the agents’ actions are executed. The m...

Several epidemiological studies have analyzed the association between oral health and social development. However, the use of different variables assessing socioeconomic status impairs the comparative analysis of their findings. The present study describes how recent dental studies have classified population segments according to categories of social stratification. We selected 86 papers on soc...

BACKGROUND Two new sets of stratification indicators--family's material affluence and adolescent's personal social position- were compared with traditional indicators of familial social position based on parental occupation and education for their ability to detect health inequality among adolescents. METHODS Survey data were collected in the Adolescent Health and Lifestyle Survey in 2003 fro...

Scholars have expressed growing interest in the relationship between legal status stratification and health. Nevertheless, the extant research often lacks theoretical underpinnings. We propose the life-course perspective as a theoretical lens with which to understand relationships between legal status stratification and health outcomes. In particular, the life-course perspective guides research...

When investigating the use of information systems within organizations, researchers inevitably make decisions relating to the grouping and classification, or “stratification,” of IT users. Most commonly, users are stratified along functional boundaries or by their membership in various communities of practice. It is important to note, however, that any such method of social stratification neces...

dormancy breaking of field maple (acer campestre l.) seed, by gibberllic acid (ga3) at 0, 250, 500 and 1000 ppm in 24 and 48 hours and stratification treatments in moist sand under warm (18-20 °c) and cold (2-4°c) conditions were investigated. effects of ga3 and stratification and their interaction on germination percent (gp) and germination speed (gs) were significant. the highest gp occurred ...

This paper explores the empirical validity of two important issues recently highlighted by disparity society theory in Japan. The first is income disparity and disparity between regular and non-regular workers. It is clear that social stratification theory has not yet analyzed these issues seriously. It has studied occupations rather than income; it has implicitly assumed that workers have regu...

Using the multiple hierarchy stratification perspective (MHSP), this paper investigated Americans’ freshwater and saltwater fishing participation in 2011. Data from the 2011 National Survey of Fishing, Hunting, and Wildlife-Associated Recreation were examined using two hierarchical generalized linear models. Level 1 variables were age, education, sex (male, female), income, and race/ethnicity. ...
