Ginther and Kahn claim that academics' beliefs about the importance of brilliance do not predict gender gaps in Ph.D. attainment beyond mathematics and verbal test scores. However, Ginther and Kahn's analyses are problematic, exhibiting more than 100 times the recommended collinearity thresholds. Multiple analyses that avoid this problem suggest that academics' beliefs are in fact uniquely pred...

This article discusses and proposes a procedure for the analysis of the univariate linear regression model with known general positive definite covariance matrix with SAS/STAT software of the SAS System. Estimation of parameters, hypothesis testing, estimation under constraints and collinearity and influence diagnostics are reviewed. An example is given to illustrate the procedure.

Hoxd genes are essential for limb growth and patterning. They are activated following a complex transcriptional regulation, leading to expression domains that are collinear in both space and time. To understand the mechanism(s) underlying collinearity, we produced and analyzed a set of mouse strains containing systematic deletions and duplications within the HoxD cluster. We show that two waves...

Gossypium tomentosum and G. darwinii are wild allotetraploid cotton species, characterized by many excellent traits, including fiber fineness, drought tolerance, and Fusarium and Verticillium wilt resistance. Based on the construction of F2 linkage groups of G. hirsutum x G. tomentosum and G. hirsutum x G. darwinii, two genetic linkage maps were compared. As a result, we found a total of seven ...

Research asserting that the visual system instantiates a global closure heuristic in contour integration has been challenged by an argument that behaviorally-detected closure enhancement could be accounted for by low-level local mechanisms driven by collinearity or "good continuation" interacting with proximity. The present study investigated this issue in three experiments. Exp. 1 compared the...

Abstract Hox genes are often clustered in animal genomes and exhibit spatial and/or temporal collinearity. It is generally believed that temporal collinearity is the major force preserving Hox clusters. However, studies combining genomic ...
