A diffusion equation has been used to study migration of early humans into the South Asian subcontinent. The diffusion equation is tempered by a set of parameters that account for geographical features like proximity to water resources, altitude, and flatness of land. The ensuing diffusion of populations is followed in time-dependent computer simulations carried out over a period of 10,000 YBP....

One of the most powerful ways to develop hypotheses regarding the biological functions of conserved genes in a given species, such as humans, is to first look at what is known about their function in another species. Model organism databases and other resources are rich with functional information but difficult to mine. Gene2Function addresses a broad need by integrating information about conse...

childtrends.org “Soft skills” are centrally important for human capital development and workforce success. A growing evidence base shows that these qualities rival academic or technical skills in their ability to predict employment and earnings, among other outcomes (Kautz, Heckman, Diris, ter Weel, & Borghans, 2014). As the workplace has modernized around the world, the demand for such skills ...

Cleaning products are associated with many health and environmental problems. Contamination of water resources by cleaning products is more likely to occur with septic tanks as sewage treatment systems especially in karstic terrains. We explored women's ideas about water sources and the risk cleaning products pose to health and sewage in Mérida, a city in the Yucatán peninsula of Mexico. Women ...

Background: Opportunities to use data and information to address challenges in international agricultural research and development are expanding rapidly. The use of agricultural trial and evaluation data has enormous potential to improve crops and management practices. However, for a number of reasons, this potential has yet to be realized. This paper reports on the experience of the AgTrials i...

Native vegetation clearing has created salinity problems in many parts of Australia. Reforestation has the potential to reduce salinity, but also reduces stream flow and this is a cause of concern. Spatial predictions of the stream flow and salinity impacts of reforestation are needed to assess the ability to achieve salinity and water resource targets. Unfortunately, our ability to predict sal...

OBJECTIVE Karigiri was set up initially to be a sanatorium with a difference, and the objective of this review is to study whether this had been achieved. METHODS A broad search of 43 various publications from Karigiri. RESULTS Stigma towards leprosy lead to the creation of this sanatorium, and within 20 years of its existence it made a significant contribution to the knowledge and treatmen...

A growing beneficial reuse of biosolids in agriculture has led to concerns about potential contamination of water resources and the food chain. In order to comprehend the potential risks of transmission of diseases to the human population, an advanced quantitative risk assessment is essential. This requires good quantitative data which is currently limited due to the methodological limitations....
