Complete intersection dimensions and Foxby classes
Let be a local ring and a finitely generated -module. The complete
intersection dimension of --defined by Avramov, Gasharov and Peeva, and
denoted \cidim_R(M)--is a homological invariant whose finiteness implies that
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 and
such that has finite Gorenstein dimension, if
has finite complete intersection dimension, then the composition
has finite Gorenstein dimension. This follows from our result
stating that, if has finite complete intersection dimension, then is
-reflexive and is in the Auslander class \catac(R) for each semidualizing
-complex .Comment: minor revisions, final version to appear in JPAA, 24 pages, uses

The Sugi Sakit Ritual Storytelling in a Saribas Iban Rite of Healing
This paper describes a Saribas Iban rite of healing called the Sugi sakit. What distinguished this rite from other forms of Saribas Iban healing was that it incorporated within its performance a long narrative epic concerned with the adventures and love affairs of an Iban culture hero named Bujang Sugi. Here I explore the language used by Iban priest bards both in telling the Sugi epic and in performing the larger ritual drama in which it was set, and look, in particular, at how the Sugi epic, which was otherwise told for entertainment, was integrated into this drama and recast by the priest bards as they performed the ritual, so that it not only entertained their listeners, but also served as a serious instrument of healing
