Existing studies of the effects of college quality on earnings typically rely on a single proxy variable for college quality. This study questions the wisdom of this approach given that a single proxy likely measures college quality with substantial error. We begin by considering the parameter of interest and its relation to the parameter estimated in the(More)

What happens when a previously uncovered labor market is regulated? We exploit the introduction of a minimum wage in South Africa and variation in the intensity of this law to identify increases in wages and formal contract coverage, and no significant effects on employment on the intensive or extensive margins for domestic workers. These large, partial(More)
A network should deploy QoS-aware path selection algorithms for efficient routing. To this end, measurements of the various characteristics of the network can provide insight into the state and performance of the network. In this paper, we present a new QoS-aware path selection algorithm for flows requiring bandwidth guarantees based on an estimation(More)
In a multi-service network, different applications have varying QoS requirements. The IETF has proposed the DiffServ architecture as a scalable solution to provide Quality of Service (QoS) in IP Networks. In order to provide quantitative guarantees and optimization of transmission resources, DiffServ mechanisms should be complemented with efficient traffic(More)
Birds of a feather have always flocked together. Building on classic works by Simmel and Park, Borgardus (1925) coined the term " social distance " to indicate whether people in one social category were willing to be closely associated with members of another category. His social distance scale used questions about the acceptability of marriage,(More)
This paper presents a new simulation method to make global network inference from sampled data. The proposed simulation method takes sampled ego network data and uses Exponential Random Graph Models (ERGM) to reconstruct the features of the true, unknown network. After describing the method, the paper presents two validity checks of the approach: the first(More)
Unilateral and bilateral lower-body heavy resistance exercises (HREs) are used for strength training. Little research has examined whether muscle activation and testosterone (TES) responses differ between these exercises. Our purpose was to compare the effects of unilateral and bilateral lower-body HRE on muscle activity using surface electromyography(More)
