Newcastle disease (ND) is a viral disease of poultry with global importance, responsible for the loss of a potential source of household nutrition and economic livelihood in many low-income food-deficit countries. Periodic outbreaks of this endemic disease result in high mortality amongst free-ranging chicken flocks and may serve as a disincentive for rural households to invest time or resource...
A home is the single largest purchase that most households make, and it is one that usually requires some debt financing. Because housing debt is such a large component of households’ balance sheets, it is important to understand the financing decision.

Most children living in child and adolescent headed households have had both pa...
Many of the studies on emerging epidemics (such as SARS and pandemic flu) use mass action models to estimate reproductive numbers and the needed control measures.

Our study of transmission dynamics in a community...
