biodiversity/biological diversity Species, genetic, and ecosystem diversity in an area, sometimes including associated abiotic components such as landscape features, drainage systems, and climate. diversity indices Measures that describe the different components of biodiversity, such as species richness (alpha diversity), beta and gamma diversity, endemicity, and higher taxon richness. ecosyste...

The paper investigates the effects of ethnic diversity on economic performance and the risk of violent conflict. Diversity has various detrimental microeconomic effects, tending to reduce public sector performance, increase patronage, and lower the level of trust among individuals. However, whether diversity adversely affects overall economic growth depends upon the political environment. Diver...

Random amplified polymorphism DNA (RAPD) is an easy, inexpensive technique for the characterization of pathogens in low-income countries. In this study we used RAPD to assess the genetic diversity of a small collection of isolates of mycobacteria from the Mexican state of Michoacan. In contrast with the low annual tuberculosis incidence in Michoacan relative to the national average, we found a ...

Low- to middle-income countries bear the overwhelming burden of the human immunodeficiency virus type 1 (HIV-1) epidemic in terms of the numbers of their citizens living with HIV/AIDS (acquired immunodeficiency syndrome), the high degrees of viral diversity often involving multiple HIV-1 clades circulating within their populations, and the social and economic factors that compromise current con...

We characterised the livestock-farming management strategies of multiple-job holders and identified which variables contributed most to the differentiation of these strategies. We hypothesised that they would mainly be differentiated by the contribution of the farming income to the total household income and the availability of the household members for farming. The multiple-job holding livesto...

the current study aims to examine the relationship between size, revenue diversity, and their interactive effects on systemic risk in private banking. the systemic risk can be measured bases on the marginal expected shortfall (mes). the mes is the average return on bank stocks on days when the return in the banking industry falls below the value at risk (var). the analysis of combined data from...
