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 âdiscussion as a way of teachingâ; 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)
William Godwin and Catholicism
This essay traces Godwinâs 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
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)
Descriptions of new species of the New World genus Perilypus Spinola (Coleoptera: Cleridae: Clerinae)
Thirty-two new species of Perilypus Spinola (Coleoptera: Cleridae: Clerinae) are described; they are Perilypus ancorus, P. angustatus, P. aquilus, P. arenaceus, P. caligneus, P. cartagoensis, P. collatus, P. comosus, P. concisus, P. copanensis, P. copiosus, P. diutius, P. divaricatus, P. elimatus, P. flavoapicalis, P. galenae, P. hamus, P. hornito, P. infussus, P. iodus, P. lateralis, P. latissimus, P. licinus, P. limbus, P. miculus, P. odous, P. orophus, P. patulus, P. punctus, turnbowi, P. violaceus, and P. yasuniensis. Included in this work are 58 line drawings and 32 color habitus photographs of primary types. To facilitate species identification the species included herein are linked to a key to Perilypus species provided in a previous review of the genus
