In Zimbabwe, people in resettled villages trust each other less than people in nonresettled villages. This does not appear to be due to differences in socially transmitted rules of behaviour. Further, there are good reasons to believe that it is not due to the self-selection of a particular type of person into resettlement. Rather, the variations appear to be due simply to a lack of familiarity...

We analyze the general phenomenon of induced-charge electro-osmosis (ICEO), nonlinear electroosmotic slip generated when an electric field acts on its own induced charge around a polarizable surface, in the context of microfluidics. Simple ICEO flows are first observed around a platinum wire in a polymer microchannel. While convenient for scaling analysis of resulting flows, this geometry prove...

This paper presents an extensive experimental study of the state-of-the-art of XML compression tools. The study reports the behavior of nine XML compressors using a large corpus of XML documents which covers the different natures and scales of XML documents. In addition to assessing and comparing the performance characteristics of the evaluated XML compression tools, the study tries to assess t...

This paper investigates whether information about generosity or fairness can be useful in reducing dispute costs and enhancing bargaining efficiency. Subjects were first screened using a dictator game, with the allocations chosen used to separate participants into two types. Mutually anonymous pairs of subjects then bargained, with a dispute cost structure imposed. Sorting with identification r...

We investigate behavior in two unprofitable games—where Maxmin strategies do not form a Nash equilibrium yet guarantee the same payoff as Nash equilibrium strategies—that vary in the riskiness of the Nash strategy. We find that arguments for the implausibility of Nash equilibrium are confirmed by our experiments; however, claims that this will lead to Maxmin play are not. Neither solution conce...

The development of a practical screening procedure for phenylketonuria and the improvement in methods of chemical analysis have led to a realization that Folling's (1934) disease of phenylketonuria is not a single entity. In this commentary, the current view on some aspects of phenylketonuria will be reviewed and the problems illustrated by experience gained in the Phenylketonuria Clinic at the...

The authors administered inventories of vocational and recreational interests and talents to 924 pairs of twins who had been reared together and to 92 pairs separated in infancy and reared apart. Factor analysis of all 291 items yielded 39 identifiable factors and 11 superfactors. The data indicated that about 50% of interests variance (about two thirds of the stable variance) was associated wi...

Continuing uncertainty about the etiology of schizophrenia calls for periodic reappraisal of relevant data and conclusions, reappraisals guided by a beacon of modest doubt to avoid the distorted views of both the zealot and the skeptic. This review does not set out to cover every possible aspect of the genetics of schizophrenia. It deals with data from recent family, twin, and adoption studies ...

A substantial part of the contribution of genetic studies to the treatment of schizophrenia involves its emphasis on reliable and valid diagnoses. One consequence of this focus is the recognition that schizophrenic illness is broader than the diagnostic entity of schizophrenia itself, and instead consists of a "spectrum" of related disorders. Because some of the symptoms in these disorders diff...
