Micro-Symposium on Orin Kerr\u27s \u27A Theory of Law\u27

For more than a century, careful readers of the Green Bag have known that “[t]here is nothing sacred in a theory of law...which has outlived its usefulness or which was radically wrong from the beginning...The question is What is the law and what is the true public policy?” Professor Orin Kerr bravely, creatively, and eloquently answered that question in his article, “A Theory of Law,” in the Autumn 2012 issue of the Green Bag. Uniquely among all theories of law that I know of, Kerr’s answer to the fundamental question of law and true public policy enables all scholars to answer that same question in their own ways. The Green Bag is pleased to be featuring his “A Theory of Law” in its first micro-symposium, and just as pleased with the quality, quantity, and diversity of the responses to the call for papers. Blessed with an abundance of good work but cursed by a shortage of space, we were compelled to select a small set – representative and excellent – of those essays to publish in the Green Bag or its sibling publication, the Journal of Law. We regret that we cannot do full justice to the outpouring of first-rate legal-theoretical commentary we received

Mu2e Technical Design Report

The Mu2e experiment at Fermilab will search for charged lepton flavor violation via the coherent conversion process mu- N --> e- N with a sensitivity approximately four orders of magnitude better than the current world's best limits for this process. The experiment's sensitivity offers discovery potential over a wide array of new physics models and probes mass scales well beyond the reach of the LHC. We describe herein the preliminary design of the proposed Mu2e experiment. This document was created in partial fulfillment of the requirements necessary to obtain DOE CD-2 approval.Comment: compressed file, 888 pages, 621 figures, 126 tables; full resolution available at http://mu2e.fnal.gov; corrected typo in background summary, Table 3.

A Multisite Preregistered Paradigmatic Test of the Ego-Depletion Effect

We conducted a preregistered multilaboratory project (k = 36; N = 3,531) to assess the size and robustness of ego-depletion effects using a novel replication method, termed the paradigmatic replication approach. Each laboratory implemented one of two procedures that was intended to manipulate self-control and tested performance on a subsequent measure of self-control. Confirmatory tests found a nonsignificant result (d = 0.06). Confirmatory Bayesian meta-analyses using an informed-prior hypothesis (δ = 0.30, SD = 0.15) found that the data were 4 times more likely under the null than the alternative hypothesis. Hence, preregistered analyses did not find evidence for a depletion effect. Exploratory analyses on the full sample (i.e., ignoring exclusion criteria) found a statistically significant effect (d = 0.08); Bayesian analyses showed that the data were about equally likely under the null and informed-prior hypotheses. Exploratory moderator tests suggested that the depletion effect was larger for participants who reported more fatigue but was not moderated by trait self-control, willpower beliefs, or action orientation
