We develop extensions of the Polya posterior that can be used to estimate population quantiles in stratified populations. In the simple case with no auxiliary information, estimates based on this extension to the Polya posterior perform similarly to the standard frequentist estimates. The Polya posterior can be extended to incorporate a variety of prior knowledge about an auxiliary characterist...

The physician workforce has steadily grown faster than the U.S. population over the past 30 years, context that is often absent in conversations anticipating physician scarcity. Policy makers addressing future physician shortages should also direct resources to ensure specialty and geographic distribution that best serves population health .

Population–environment debates in Australia are at an impasse. While the ability of this continent to sustain more migrants has attracted persistent scrutiny, nuanced explorations of diverse migrant cultures and their engagements with Australian landscapes have scarcely begun. Yet as we face the challenges of a climate changing world we would undoubtedly benefit from the most varied knowledges ...

The study reported here assessed residents' perception of small, fast-growing coastal community on issues of quality of life, conservation, and growth. Data for the study were collected from an on-site survey in Aransas County, Texas from 2006 to 2007. Results show that the residents are concerned about preserving their natural resources, maintaining a small town atmosphere in their community, ...

We consider the dynamics, existence and stability of the equilibrium states for large populations of individuals who can play various types of non–cooperative games. The players imitate the most attractive strategies, and the choice is motivated not only by the material payoffs of the strategies, but also by their popularity in the population. The parameter which determines the weights of both ...

This paper builds a small-open-economy, non-scale-growth model with negative population growth and investigates the relationship between trade patterns and per capita consumption growth. Under free trade, if the population growth rate is negative and its absolute value is small, the home country becomes an agricultural country. Then, the long-run growth rate of per capita consumption is positiv...

This paper discusses the disease-free and endemic equilibrium points of a SVEIRS propagation disease model which potentially involves a regular constant vaccination. The positivity of such a model is also discussed as well as the boundedness of the total and partial populations. The model takes also into consideration the natural population growing and the mortality associate to the disease as ...

The rapid population growth of many African cities has important implications for population health, yet little is known about factors contributing to increasing population, such as the fertility of internal migrants. We examine whether in-migrants to Kinshasa have different fertility patterns than lifetime Kinshasa residents, and identify characteristics of migrants that may explain difference...

This paper examines the effects of lifetime learning on the diversity and fitness of a population. Our experiments measure the phenotypic diversity of populations evolving by purely genetic means (population learning) and of others employing both population learning and lifetime learning. The results obtained show, as in previous work, that the addition of lifetime learning results in higher le...
