This paper develops a semi-parametric Bayesian regression model for estimating heterogeneous treatment effects from observational data. Standard nonlinear regression models, which may work quite well for prediction, can yield badly biased estimates of treatment effects when fit to data with strong confounding. Our Bayesian causal forests model avoids this problem by directly incorporating an es...

(2) A thin acrylic plate is rigidly attached to this tube in such a way that the lumen of the tube opens onto the upper surface of the plate. This plate (8 mm. in diameter and approximately circular in outline) is curved to fit and firmly sutured to the sclera. When covered by a flap of conjunctiva and Tenon's capsule, the plate forms the floor of a blel) wvhich is in free communication with th...

Fecal immunochemical testing (FIT) is superior to guiac-based testing if we are looking for blood in stools, as it has better one-time colorectal cancer sensitivity and specificity and better patient acceptance. In this issue of the journal, Cai and colleagues (beginning on page 1572) and Khalid-de Bakker and colleagues (beginning on page 1563) present new information about the one-time test pe...

We adopted a person–organization (P–O) fit framework to examine applicant attraction to an organization in the context of Web-based recruitment. A total of 121 undergraduate business students participated in a two-stage study first by completing a paper-and-pencil survey and second, by visiting a fictitious recruitment Web site in which the researchers manipulated the fit feedback information p...

1 Anscombe’s term for such knowledge in Intention is “practical knowledge”. However, I have avoided that term as I wish to defend the idea that agents have a distinctive non-observational knowledge of their actions without being committed to her claims about the existence of a kind of knowledge with a reverse direction of fit from ordinary knowledge. 2 The idea originates in English speaking ph...
