We use instrumental variable methods to investigate whether the impact of parental smoking habits on their children’s smoking decisions is a causal one. We find evidence of same-sex role models in two-parent households: mothers play a crucial role in determining their daughters’ smoking decisions, while fathers’ smoking habits are primarily imitated by(More)
Paired liver and kidney samples from 100 free-range cattle in different parts of Jamaica were analyzed for essential and non-essential trace elements. We found significant enrichment of elements in the kidney (K) compared to the liver (L) with the K/L concentration ratios being 5.2 for Cd, 4.1 for Pb, 3.5 for Se and 2.1 for As, but the Cu contents of the(More)
Household debt repayment behavior has been understudied, especially empirically, despite the heightened debate on rising household debt, personal bankruptcy filings, and arrears. In this paper, we use data from the European Community Household Panel to analyze the determinants of household debt arrears. The paper's primary aim is to understand the role of(More)
Despite the heightened debate on rising household debt, personal bankruptcy filings, and arrears, household debt repayment behaviour has been understudied, especially at the empirical level. This paper uses data from the European Community Household Panel to analyze the determinants of household debt arrears. The paper’s primary aim is to understand the(More)
Vector field rendering is difficult in 3D because the vector icons overlap and hide each other. We propose four different techniques for visualizing vector fields only near surfaces. The first uses motion blurred particles in a thickened region around the surface. The second uses a voxel grid to contain integral curves of the vector field. The third uses(More)

Households are constrained if they want to borrow, but banks restrict their lending. This paper separately identifies (using appropriate exclusion restrictions) the demand for debt, and the maximum amount agents can borrow when it is unknown which consumers are constrained. Using data from the CEX, it estimates that between 26 percent and 31 percent of(More)
Reconciling the Estimates of Potential Migration into the Enlarged European Union * This paper briefly reviews the existing literature on potential migration into the enlarged European Union, reconciles the results with recent evidence and presents an additional migration scenario. The estimation procedure accounts for both sending and receiving countries'(More)
Several approaches to intelligent tutoring monitor the learners actions in order to understand his/her abilities. This requires that the learner's actions can be monitored. In traditional singleuser command interfaces this is straightforward. As a result action tracking has not been subject to much study. However, in more advanced interfaces and(More)
