BACKGROUND In practically every human culture, the use of arthropods as medicinal resources has been reported. In Mexico, the Mayan people mainly use plants but occasionally also animals and minerals in their medicine. This article is the first to report the traditional use of the tarantula Brachypelma vagans by medicine men in the Chol community, an ancient indigenous group that inhabits the s...

Sustaining access to healthcare in a resourcepoor setting is a key challenge in achieving global health.1 While there exist huge differences in healthcare systems between developing and developed countries, shortages of doctors and other health professionals in rural and remote areas are universal issues.2 In rural areas, both patient-specific and extrinsic factors affect access to healthcare.3...

Let M be a simply connected complex submanifold of C . We prove that M is irreducible, up a totally geodesic factor, if and only if the normal holonomy group acts irreducibly. This is an extrinsic analogue of the well-known De Rham decomposition theorem for a complex manifold. Our result is not valid in the real context, as it is shown by many counter-examples.

Since their inception, social networking sites (SNSs) have experienced exponential growth. While substantial research has been dedicated to users’ initial adoption of SNSs, the fall of MySpace reminds us that the long-term success of SNSs depends on users’ post adoption staying power. Inspired by this, this work-in-progress investigates users’ “stickiness” with a specific SNS. Based on Li et al...

This paper reports on an empirical investigation of the relationship between print and hypertext reading skills. Subjects in the study were university students at a public Midwestern university. A repeated-measures, counter-balanced design was employed. Subjects were categorized as highand low-ability readers based on a standardized measure of reading achievement. Experimental tasks required su...

Content contribution from individuals is critical to the viability of online communities. In this study we identify the factors that are associated with the quantity and the quality of content sharing in a photo sharing community, where the act of content creation is decoupled from the act of content sharing. We draw on theories of intrinsic and extrinsic motivation, and find that the prospect ...

We examine three theories of caste and community using new data on social networks among residents of a south Indian village. The first theory treats individual caste groups as separated communities driven by the Brahmanical ideology of hierarchy based on purity and pollution. The second theory departs from the first by placing kings and landlords at the centre of rural (primeval) social struct...
