This article examines the empirical basis for current criminal sentencing guidelines being used in Cook County, Illinois. Unlike in many other sentencing reforms, guidelines have generally been developed out of an empirical analysis of past sentencing decisions through the identification of variables most predictive of sentence. However, when the statistical analysis is inadequate or faulty, the resultant sentencing guidelines must be questioned. Presented is a reanalysis of the original data used to develop Cook County's sentencing guidelines. Generally, the current sentencing guidelines used in Cook County are not found to be predictive of sentence. Implications of this finding are discussed.

This study reports on a search for racial disparities in the value of baseball cards for Black and White members of the National Baseball Hall of Fame (HOF). The study's sample of 51 players was derived from the population of the 96 players elected to the HOF since 1936 by the Baseball Writers of America. Although the authors found that race produced no statistical difference in Black and White players' card values, they did observe that players' career performance plus the availability of a player's card (scarcity) exerted a significant effect on the value of cards. The study concludes with a discussion of possible interpretations of these findings.

AbstractThe Colorado Twin Registry (CTR) is a population-based registry formed from birth and school records including twins born between 1968 and the present. Two previous reports on the CTR [Rhea et al., (2006). Twin Research and Human Genetics, 9, 941–949; Rhea et al., (2013).Twin Research and Human Genetics, 16, 351–357] covered developments in the CTR through 2012. This report briefly summarizes previously presented material on ascertainment and recruitment and the relationships between samples and studies, discusses developments since 2012 for four previously described twin samples, describes two new samples and their complementary studies and expands on two subjects briefly mentioned in the last report: a history of genotyping efforts involving CTR samples, and a survey of collaborations and consortia in which CTR twins have been included. The CTR remains an active resource for both ongoing, longitudinal research and the recruitment of new twin samples for newly identified research opportunities.
