The \u3ci\u3ePlatycerus\u3c/i\u3e (Coleoptera, Lucanidae) of California, with the recognition of \u3ci\u3ePlatycerus cribripennis\u3c/i\u3e Van Dyke as a valid species

Th e status of Platycerus cribripennis Van Dyke, generally treated as a synonym of P. marginalis Casey, has been unclear. Here we recognize and redescribe P. cribripennis, which is endemic to the coastal mountains of California, as a valid species due to its unique morphology. A key to the Platycerus of California is presented, and the distributions of the recognized species are discussed

A Critical Thinking Benchmark for a Department of Agricultural Education and Studies

Due to an ever changing world where technology seemingly provides endless answers, today’s higher education students must master a new skill set reflecting an emphasis on critical thinking, problem solving, and communications. The purpose of this study was to establish a departmental benchmark for critical thinking abilities of students majoring in agricultural education and studies. Seventy-five senior-level undergraduates completed a Critical Thinking Assessment Test (CAT) during the spring 2013 semester. A one-sample t-test utilizing national norm data and a step-wise regression model analyzing predictors of critical thinking ability were used to address research objectives. The only critical thinking skill area where participants’ mean scores were statistically higher than the national norm mean score was in the ability to summarize a pattern of results from a graph without making inappropriate inferences. Further, step-wise regression for total critical thinking score revealed ACT score was the only significant predictor of overall critical thinking ability

The impact of a capstone farm management course on critical thinking abilities

While many studies about the 4-H camping experience focus on youth who are campers, few studies examine the outcomes of the experience for counselors. This study examines the extent to which 4-H camp results in transformative learning for 4-H members who serve as camp counselors, examines the perceived changes that occur within counselors, and describes the factors and characteristics of camp that result in personal transformation. The population for this study was 2012 Minnesota 4-H camp counselors. Using the Transformative Learning and the Camp Experience Staff Member Survey, the results indicated that camp counselors experienced transformative learning. Major personal changes involved developing skills for working with children and exposure to new people, activities, and experiences. Factors leading to personal transformation included the opportunity to be role models and positively impact children, opportunities for leadership and challenge, and camp traditions. This study provides support for strong and intentional camp counseling experiences that can positively impact the individual, 4-H campers, and later, the communities in which these camp counselors reside

Text over Intent and the Demise of Legislative History

The following is the transcript of a 2016 Federalist Society panel entitled: Text Over Intent and the Demise of Legislative History. The panel originally occurred on November 17, 2016 during the National Lawyers Convention in Washington, D.C. The participants were: Prof. Thomas W. Merrill, Charles Evans Hughes Professor of Law, Columbia Law School; Prof. Michael S. Paulsen, Distinguished University Chair and Professor, University of St. Thomas School of Law; Prof. Saikrishna Prakash, James Monroe Distinguished Professor of Law, University of Virginia School of Law; Prof. Lawrence B. Solum, Carmack Waterhouse Professor of Law, Georgetown University Law Center. The moderator was the Hon. Sandra Segal Ikuta, Judge on the U.S. Court of Appeals, Ninth Circuit

Clean Positive Operator Valued Measures

In quantum mechanics the statistics of the outcomes of a measuring apparatus is described by a positive operator valued measure (POVM). A quantum channel transforms POVM's into POVM's, generally irreversibly, thus loosing some of the information retrieved from the measurement. This poses the problem of which POVM's are "undisturbed", namely they are not irreversibly connected to another POVM. We will call such POVM clean. In a sense, the clean POVM's would be "perfect", since they would not have any additional "extrinsical" noise. Quite unexpectedly, it turns out that such cleanness property is largely unrelated to the convex structure of POVM's, and there are clean POVM's that are not extremal and vice-versa. In this paper we solve the cleannes classification problem for number n of outcomes n<=d (d dimension of the Hilbert space), and we provide a a set of either necessary or sufficient conditions for n>d, along with an iff condition for the case of informationally complete POVM's for n=d^2.Comment: Minor changes. amsart 21 pages.
