Validation of mobile ad hoc network protocols relies almost exclusively on simulation. The value of the validation is, therefore, highly dependent on how realistic the movement models used in the simulations are. Since there is a very limited number of available real traces in the public domain, synthetic models for movement pattern generation must be used. However, most widely used models are ...

This paper reports on a preliminary investigation of surname distributions as a measure long run social mobility. In England this suggests two surprising claims. First, England, all the way from the heart of the Middle Ages in 1200 to 2009, is a society without persistent social classes, at least among the descendants of the medieval population. It was a world of complete social mobility, with ...

Mobile devices, access and service was provided via a third generation wireless network to a focal application, Pennsylvania’s Justice NETwork (JNET), a secure web-based portal connecting authorized users to a set of 23 federated criminal justice and law enforcemen...

Information on parental class (1960) and own mid-life social class (1980 and 1990) was retrieved from the censuses and cat...

We analyse the reservation wages of firstand second-generation migrants, based on rich survey data of the unemployed in Germany. Our results confirm the hypothesis that reservation wages increase over migrant generations and over time, suggesting that the mobility benefit of immigration may be limited in time.

Social capital is one of the influential concepts in social science to understand contemporary societies. It has been found to influence many aspects of social life, directly or indirectly. It is also increasingly explored in relation to Information and Communications Technology (ICT). Nevertheless, social capital is a challenging variable to research, in part because of its multiple divergent ...

The rate of technological growth is likely to be affected by the way in which the stock of human resources is allocated. This social sorting of individuals over occupations is (partly) a market outcome, affected by the relative return to intellectual ability such as intelligence and other individual merits. To analyze how the social sorting is affected by growth, we present a stylized endogenou...

Understanding the sources of the social class achievement gap in education is an important step toward ensuring that education serves its purpose as an engine of social mobility. The goal of the current article is to provide a brief overview of the sources of the social class achievement gap as well as interventions aimed at closing this gap. We outline three major sources of the social class a...
