Balcus violaceus (Fabricius) : senior synonym of Balcus niger Sharp and B. signatus Broun (Coleoptera: Cleridae: Clerinae)

The elytra of Balcus signatus Broun (Coleoptera: Cleridae: Clerinae) from New Zealand have pale markings. Such markings, most prominently found in females, represent intraspecific variations of Balcus violaceus (Fabricius). Accordingly, Balcus signatus Brown is synonymized with Notoxus violaceus Fabricius, new synonymy. Four habitus figures of Balcus violaceus (Fabricius) are presented to display the range of elytral color variation in the species

Teaching history is talking history

Like many teachers, my early practice was in equal parts reiteration and repudiation of the models to which I had been exposed as a student. As a consequence of my own shyness I took great efforts not to place students in uncomfortable positions, particularly with regard to speaking in class. In retrospect, I can appreciate that I did not encourage or provide adequate opportunities for discussion. As I designed and reflected on my own pedagogic initiatives, it became clear that discussion underpinned the learning taking place in all classroom activities. Brookfield and Preskill have thoroughly and perspicaciously enumerated the myriad learning benefits accruing from the use of ―discussion as a way of teaching‖; and I am now convinced that it is integral to the learning process. Thus, I attempt to create a classroom in which students are encouraged to talk and feel comfortable doing so

Stability of Utility Maximization in Nonequivalent Markets

Stability of the utility maximization problem with random endowment and indifference prices is studied for a sequence of financial markets in an incomplete Brownian setting. Our novelty lies in the nonequivalence of markets, in which the volatility of asset prices (as well as the drift) varies. Degeneracies arise from the presence of nonequivalence. In the positive real line utility framework, a counterexample is presented showing that the expected utility maximization problem can be unstable. A positive stability result is proven for utility functions on the entire real line

New taxa of Epiphloeinae Kuwert (Cleridae) and Chaetosomatidae Crowson (Coleoptera: Cleroidea)

Twenty-one new taxa of Cleridae and one of Chaetosomatidae are described including four new genera: Acanthocollis, Decaphloeus, Megaphloeus, and Stegnoclava. Twenty new species are described: five species of Amboakis Opitz (A. ampla, A. antegalba, A. diffusa, A. demagna, A. waodani, one species of Epiphloeus Spinola (E. erwini), four species of Madoniella Pic (M. aspera, M. darlingtoni, M. divida, M. spilota), two species of Plocamocera Spinola (P. clinata, P. lena), seven species of Pyticeroides Kuwert (P. latisentis, P. moraquesi, P. parvoporis, P. pinnacerinis, P. pullis, P. turbosiris, P. ustulatis), and one species of Chaetosomatidae (Chaetosoma colossa)

Iwasawa invariants of Galois deformations

We study the behavior of Iwasawa invariants among ordinary deformations of a fixed residual Galois representation taking values in a reductive algebraic group G. In particular, under the assumption that these Selmer groups are cotorsion modules over the Iwasawa algebra, we show that the vanishing of the mu invariant is independent of the deformation, while the lambda invariant depends only on the ramification. This generalizes work of Greenberg-Vatsal and Emerton-Pollack and the author in the case G = GL(2)

William Godwin and Catholicism

This essay traces Godwin‘s changing attitude to Catholicism by exploring a variety of texts generally considered marginal to his oeuvre and a hitherto unexamined selection of his unpublished manuscripts
