Spreading the message: teaching music librarianship by distance learning

A course in music librarianship has been offered at the University of Illinois at Urbana-Champaign for many years. However, it is only since 2008 that the course has been offered online. The move from a traditional classroom environment to an online one raises several pedagogical and practical issues, some of which are discussed in the present article. The technology used to deliver courses online from the University of Illinois is also examined, and some information is also provided about the use of online course management software to deliver music librarianship courses at the University of Aberystwyth (UK). An increase in the number of courses offered online in this way will,one hopes, lead to greater course enrolment by students.published or submitted for publicationis peer reviewe

Forensic hypnosis

Hypnosis has long generated controversy as a recall enhancement method. Concerns about hypnosis are warranted by findings of a tradeoff between the number of memories recalled and memory accuracy. Moreover, witnesses often express confidence in hypnotically augmented remembrances, regardless of their accuracy, increasing the risk jurors will be biased based on convincing yet inaccurate information. Although misleading questions appear to be equally or more problematic, raising concerns about singling out hypnosis as a uniquely prejudicial technique, other recall improvement methods (e.g., cognitive interview and asking individuals to do their best to recall target events) appear to pose less memory risks than hypnotic procedures

Complete intersection dimensions and Foxby classes

Let $R$ be a local ring and $M$ a finitely generated $R$-module. The complete intersection dimension of $M$--defined by Avramov, Gasharov and Peeva, and denoted \cidim_R(M)--is a homological invariant whose finiteness implies that $M$ is similar to a module over a complete intersection. It is related to the classical projective dimension and to Auslander and Bridger's Gorenstein dimension by the inequalities \gdim_R(N)\leq\cidim_R(N)\leq\pd_R(N). Using Blanco and Majadas' version of complete intersection dimension for local ring homomorphisms, we prove the following generalization of a theorem of Avramov and Foxby: Given local ring homomorphisms $\phi\colon R\to S$ and $\psi\colon S\to T$ such that $\phi$ has finite Gorenstein dimension, if $\psi$ has finite complete intersection dimension, then the composition $\psi\circ\phi$ has finite Gorenstein dimension. This follows from our result stating that, if $M$ has finite complete intersection dimension, then $M$ is $C$-reflexive and is in the Auslander class \catac(R) for each semidualizing $R$-complex $C$.Comment: minor revisions, final version to appear in JPAA, 24 pages, uses xypic, Dedicated to Luchezar L.
