This study examines regional convergence in per capita personal income in the US and Canada. We find that the disparity in real per capita income levels across US states (Canadian provinces) has declined, but income levels are not identical. Income levels become more aligned once costs of living are accounted for in relative per capita income series. US states (Canadian provinces) converge at a...

As computer technology becomes increasingly prevalent throughout society, concerns have been raised about an emerging "digital divide" between those children who are benefitting and those who are being left behind. This article presents results from new analyses of national survey data describing children's differential access to computers in school and at home, and the varying conditions that ...

Exposure to radiation from different types of television sets was measured to ascertain the levels of hazards posed to the human biological system. Measurement of the annual radiation dose hazards was performed using a halogen-quenched GM tube with thin mica end window having a density of 1.5 mg/cm2, effective window diameter of 0.360 inch and side wall of 0.012 inch thick. The GM tube was plac...

We present novel results that relate energy and information transfer with sensitivity to initial conditions in chaotic multi-dimensional Hamiltonian systems. We show the relation among Kolmogorov-Sinai entropy, Lyapunov exponents, and upper bounds for the Mutual Information Rate calculated in the Hamiltonian phase space and on bi-dimensional subspaces. Our main result is that the net amount of ...

BACKGROUND Low back pain (LBP) is one of the most common and costly healthcare problems worldwide. Disability from LBP is associated with maladaptive beliefs about the condition, and such beliefs can be influenced by public health interventions. While socioeconomic status (SES) has been identified as an important factor in health literacy and inequalities, not much is known about the associatio...

Why Do Self-Employed Immigrants in Denmark and Sweden Have Such Low Incomes? When studying income differences and income distribution, the self-employed are often excluded from the population studied. There are several good reasons for this, for example that incomes from self-employment are not reported to the same extent as incomes from being an employee. On the other hand it is a problem to e...

Integration of energy crops into agricultural landscapes could promote sustainability if they are placed in ways that foster multiple ecosystem services and mitigate ecosystem disservices from existing crops. We conducted a modeling study to investigate how replacing annual energy crops with perennial energy crops along Wisconsin waterways could affect a variety of provisioning and regulating e...

BACKGROUND There is paucity of data on the cost and rate of hospitalization in children with sickle cell anaemia (SCA) in most developing nations. OBJECTIVE To estimate the rate and cost of hospitalization in children with SCA in Nigeria and evaluate the economic burdens on their families. METHODS The number and duration of hospitalizations; estimated aggregate family's monthly income, cost...
