Over the past decade, the proliferation of election surveys has worked to undergird the electoral system in Mexico and to make electoral fraud more difficult. In the presidential elections of 1994, significant controversies arose as to survey methodologies, but by the congressional elections of 1997 the fierce debates over methodologies had subsided. Substantively, the surveys confirm the accuracy of the vote count in 1998, allow profiles of voters to be constructed for the three most important parties and mark declines in the support of the once dominant Partido Revolucionario Institucional.  相似文献

For more than two decades, economists and sociologists have pursued parallel cross-national quantitative investigations of the determinants of economic development. These investigations have proceeded in mutual ignorance despite the often large overlap in statistical methods and data employed. Apparently contradictory findings have resulted, especially regarding the impacts of international trade and foreign direct investment. We find that there are two factors that account for these inconsistent results. One key factor is the use of different variables to measure international trade and investment, the choice of which is in turn driven by underlying differences in theoretical motivations. A second important difference involves sociologists’ greater preoccupation with more complex multivariate models versus economists’ greater willingness to focus on individual variables in multivariate regressions while viewing others as “controls.” A major finding of our survey is that when thesame variables are used, the results of economists and sociologists tend to be consistent, rather than contradictory (as might have occurred, for example, because of the use of different samples of countries or time periods, or the use of other variables included in the regression equations). We also consider some studies whose purviews go beyond economic growth to consider factors such as income inequality, physical quality of life, demographic change, and basic needs provisioning.

The ongoing debate about the FDA approval of BiDil in 2005 demonstrates how the first racially/ethnically licensed drug is entangled in both Utopian and dystopian future visions about the continued saliency of race/ethnicity in science and medicine. Drawing on the sociology of expectations, this paper analyzes how scientists in the field of pharmacogenetics are constructing certain visions of the future with respect to the use of social categories of race/ethnicity and the impact of high-throughput genotyping technologies that promise to transform scientific practices.  相似文献

We examined whether eyewitness identification latencies for sequential line‐up decisions indicate an optimum time boundary that reliably discriminates accurate from inaccurate decisions. Participants (N = 381) observed a crime simulation and attempted two separate identifications from target‐present or target‐absent sequential line‐ups. As has previously been found with simultaneous line‐ups, the optimum time boundary identified did not reliably discriminate accurate from inaccurate identifications for both line‐up targets. Diagnosticity for choosers was, however, much higher at very high confidence levels than at lower levels. Possible reasons for why one index of signal strength (confidence), but not another (latency), might postdict accuracy within the sequential framework were presented.  相似文献
