Capital accumulation can modify the relative productivity between skilled and unskilled workers, leading to changes in the wage structure. In particular, if capital goods are relatively more complementary to skilled workers, a positive correlation between investment in physical capital and the wage premium would be expected. In this paper, we present evidence for this hypothesis by taking advan...

For agents, one of the advantages of being part of a society is the satisfaction of those goals whose success depends on the abilities of other agents. In turn, societies are controlled by norms and, consequently, agents must be able first to model the society in which they exist, and then to identify the different relationships, due to norms, in which they might be involved in order to act app...

Under the influence of Web 2.0 Work (purposeful directed action) is democratised moving it away from productionist metaphysics. Web 2.0 symbolises a cultural phenomenon summarised as a collection of emerging technologies and methodologies that, in the enterprise, provides for a shift in the asymmetric distribution of power such that the technological human has access to mechanisms and processes...

Residential segregation, by definition, leads to racial and socioeconomic disparities in neighborhood conditions. These disparities may in turn produce inequality in social and economic opportunities and outcomes. Because racial and socioeconomic segregation are not independent of each other, however, any analysis of their causes, patterns, and effects must rest on an understanding of the joint...

2.1 Investment in education has played a central role in Sri Lankan government policy for several generations. Key aims of public education policy have included: (i) enhancing economic equity; (ii) promoting inter-generational social mobility; (iii) increasing labor productivity and earnings through human capital accumulation; and (iv) producing a healthy and prosperous society. The economic an...

This paper aims to provide some insights of a longitudinal case study of the adoption and use of social media technologies by the New South Wales (NSW) state emergency service (SES), with a focus on social media adoption factors. The study identifies a set of internal and external factors explaining the adoption and use of social media by the NSW SES including: the social media bandwagon effect...

We establish necessary conditions for the appearance of both apparent horizons and singularities in the initial data of spherically symmetric general relativity when spacetime is foliated extrinsically. When the dominant energy condition is satisfied these conditions assume a particularly simple form. Let ρMax be the maximum value of the energy density and l the radial measure of its support. I...

The dynamics of inequality are studied in a model of human capital accumulation with credit constraints. This model admits a multiplicity of steady state skill ratios that exhibit varying degrees of inequality across households. The main result studies equilibrium paths. It is shown that an equilibrium sequence of skill ratios must converge monotonically to the smallest steady state that exceed...

This paper investigates the modelling of confusion in product encryption by statistical means, to support understanding of the avalanche effect of the continuous application of an encryption step or round. To facilitate the modelling, a metric for confusion is proposed and its appropriateness and properties verified against broadly accepted theoretical assumptions. The regression analysis showe...

abstract previous research have shown that physical and mental illness and mortality are influenced by class status, material life standards, genetics and infection, but today social context attracted attention. in this paper social capital as a composition of social trust, support and relations seen as a mental health determinant. the aim of this paper is examining the relationship between soc...
