Electron neutrino charged-current quasielastic scattering in the MINERvA experiment
The electron-neutrino charged-current quasielastic (CCQE) cross section on
nuclei is an important input parameter to appearance-type neutrino oscillation
experiments. Current experiments typically work from the muon neutrino cross
section and apply corrections from theoretical arguments to obtain a prediction
for the electron neutrino cross section, but to date there has been no
experimental verification of the estimates for this channel at an energy scale
appropriate to such experiments. We present the first measurement of an
exclusive reaction in few-GeV electron neutrino interactions, namely, the cross
section for a CCQE-like process, made using the MINERvA detector. The result is
given as differential cross-sections vs. the electron energy, electron angle,
and square of the four-momentum transferred to the nucleus, . We also
compute the ratio to a muon neutrino cross-section in from MINERvA. We
find satisfactory agreement between this measurement and the predictions of the
GENIE generator.Comment: Presentation at the DPF 2015 Meeting of the American Physical Society

Feminist Collaboration in the Art Academy
Women\u27s activity in the visual arts both in and outside of the art institutions of Europe and the United States reveals a history of collaboration in artistic production and political activism This paper analyzes the effects of feminist collaboration upon the disciplines of art, the pedagogy of art, and the administration of art institutions. In Part I, the authors review the impact of feminist collaboration in art history, aesthetics, art criticism, and art production. Part II provides examples of collaborative experiences of women in higher education art institutions and in some art communities in the United States, Scandinavia, and Italy. Three conclusions emerged from the review: (a) Collaboration facilitated women\u27s entry into the visual arts; (b) collaborative dialogue has changed the academic structures of art criticism and art history, but collaboration has had a minimal effect in the areas of aesthetics and art production; and (c) collaboration has not resulted in a significant change in the administration or pedagogy of art institutions
Business Ethics and Ideals
John Hasnas (2013) argues for a “Principles Approach” to supplant normative theory and casuistry in business ethics pedagogy. This Commentary argues some normative theory ought still to have some place in business ethics education and that the problems Hasnas sees in business ethics pedagogy only tell half the story
Taxonomic revision of the New World genus Callotillus Wolcott (Cleridae, Tillinae), with the description of the new genus Neocallotillus, and an illustrated key of identification to species
Citation: Burke AF, Zolnerowich G (2016) Taxonomic revision of the New World genus Callotillus Wolcott (Cleridae, Tillinae), with the description of the new genus Neocallotillus, and an illustrated key of identification to species. ZooKeys 617: 65–89. doi: 10.3897/zookeys.617.9970The New World checkered beetle genus Callotillus Wolcott, 1911 is revised and the new genus Neocallotillus established. The subspecies Callotillus elegans vafer Wolcott is synonymized with the nominal subspecies, C. elegans elegans (Erichson), which is transferred to, and designated as the type species of Neocallotillus gen. n. as Neocallotillus elegans (Erichson, 1847), comb. n. Two additional species are transferred from Callotillus to the new genus: Neocallotillus intricatus (Wolcott & Dybas, 1947), comb. n. and N. crusoe (Wolcott, 1923), comb. n., the latter tentatively and based on Wolcott’s original description. Callotillus is now composed of two species: C. eburneocinctus Wolcott, 1911 and C. bahamensis Vaurie, 1952. All abovementioned species except N. crusoe are diagnosed and redescribed. In the absence of reference material of Neocallotillus crusoe, Wolcott’s original description is transcribed. An illustrated key to species is provided. Characters of taxonomic relevance are illustrated and discussed. Updated distribution maps and locality data for all specimens examined are presented
