Current research on the patterns and processes underpinning host specificity in parasites goes well beyond field observations. Molecular studies are used increasingly on a range of parasite taxa to uncover levels of specificity not recognized previously. By contrast, the widespread use of experimental infections indicates that new host-parasite combinations are achieved easily in the laboratory...

The Foxp3+ T cell lineage is thought to arise from self-specific precursors during development. By using a unique mouse model, Pacholczyk et al. (2007) present compelling evidence that self-specific cells are exceedingly rare among Foxp3(-) and, surprisingly, Foxp3+ subsets.

The Levins metapopulation model describes the dynamics of several populations in patches of suitable habitat. These populations may go extinct, leaving empty patches of suitable habitat, but these empty patches may be recolonized by other populations via dispersal. The metapopulation can therefore persist if recolonizations balance local extinctions. This simple model has been criticized for it...

profession. However, the main focus of evidence-based practice has been in the clinical and research realms; with clinicians and researchers often bearing the brunt of criticism concerning the lack of evidence supporting physiotherapy management practices. In the move towards global evidencebased practice, very little attention has been given to the practices of physiotherapy education programs...

Triclosan, the antimicrobial agent marketed for its germ-fighting capability in personal care products, is coming under close scrutiny. In April 2010 the U.S. Food and Drug Administration (FDA) announced it is conducting a scientific and regulatory review of triclosan in FDAregulated products, with publication of results expected in spring 2011. The agency also is collaborating with the U.S. En...

This paper describes a Bull US Applied Research Laboratory project to build a collaborative inspection and review system called Scrutiny using ConversationBuilder from the University of Illinois at UrbanaChampaign. The project has several distinct aspects: technology oriented research, prototype building, experimentation, and tool deployment/ technology transfer. Described are the design of the...

The Health Level 7 (HL7) Reference Information Model (RIM) was once incepted as an object oriented information model to harmonize the definition of HL7 messages across different application domains. On the heels of the hugely successful HL7 version 2, version 3 and the RIM has received significant attention and credit and in turn is increasingly subjected to criticism. In this paper the authors...

Since its final version and publication in 1916, it is widely reported in several specialized textbooks and research articles that General Relativity theory reduces to Newton's theory of gravity in the limit of a weak gravitational field and slowly moving material bodies. In the present paper, the so-called reducibility of Einstein's geodesic and field equations, to Newton's equation of motion ...
