Explaining altruistic cooperation is one of the greatest challenges faced by sociologists, economists, and evolutionary biologists. The problem is determining why an individual would carry out a costly behavior that benefits another. Possible solutions to this problem include kinship, repeated interactions, and policing. Another solution that has recently received much attention is the threat o...

Nearly two million more young Americans under the age of 30 voted in the 2008 presidential elections as compared to the 2004 elections, according to new Census data analyzed and released by CIRCLE. The increase is a continuation of the trend observed in the 2004 and 2006 elections. Youth turnout was 11 percentage points higher than in 1996, which was the low point after decades of decline. Whil...

Webster’s asserts that color is “a phenomenon of light or visual perception that enables one to differentiate otherwise identical objects,” and then goes on to say that the Latin root is celare, “to conceal.” It’s a fine definition, because human perception of color is seamless to the extent that it conceals from us almost every causal detail. This talk will discuss common sources of light, the...

Humans have always done nonmonotonic reasoning, but rigorous monotonic reasoning in reaching given conclusions has been deservedly more respected and admired. Euclid contains the first extended monotonically reasoned text available to a large public. I suspect that even Euclid did nonmonotonic reasoning in arguing for the postulates. It is unfortunate that the rigorous monotonic reasoning of Eu...

(Received for publication, July 21, 1952) Many histological studies1),2),3) on the innervation of mammalian tongues have been reported and praiseworthy results achieved histherto, but much seems yet left unexplored, and in particular, many questions are still waiting solution in connection with dog tongue. Recently, much licht has been thrown on the subject of innervation of human tongue by the...

People who have gout may contend with an increased risk of type 2 diabetes, and women seem more vulnerable than men, according to a large population-based study. The researchers at Harvard Medical School analyzed data from gout patients, and from those without the disease, in the United Kingdom's Health Improvement Network (THIN) database. They found a higher incidence of type 2 diabetes among ...

Among the Milky Way satellites discovered in the past three years, TriangulumII has presented the most difficulty in revealing its dynamical status. Kirby et al. identified it as the most dark-matter-dominated galaxy known, with a mass-to-light ratio within the half-light radius of M L 360

The paper starts by sketching the key modes of spatial data analysis (point pattern, continuous surface, areal/lattice), and how they fit into legacy GIS data models. Based on development work with the GRASS release 5 team (GRASS 5 is GPL), status is reported for using R in the analysis of sites (point) data and for raster data, as well as using R as an intermediate analytical environment for i...
