Weierstrass representations for harmonic morphisms on Euclidean spaces and spheres
We construct large families of harmonic morphisms which are holomorphic with
respect to Hermitian structures by finding heierarchies of Weierstrass-type
representations. This enables us to find new examples of complex-valued
harmonic morphisms from Euclidean spaces and spheres.Comment: Minor revision adding example. Latex 2.09. 14 page
Twistor theory on a finite graph
We show how the description of a shear-free ray congruence in Minkowski space
as an evolving family of semi-conformal mappings can naturally be formulated on
a finite graph. For this, we introduce the notion of holomorphic function on a
graph. On a regular coloured graph of degree three, we recover the space-time
picture. In the spirit of twistor theory, where a light ray is the more
fundamental object from which space-time points should be derived, the line
graph, whose points are the edges of the original graph, should be considered
as the basic object. The Penrose twistor correspondence is discussed in this
context
Imprisoned bodies - free minds: Incarcerated women and liberatory learning.
Using women\u27s literature as a medium for self-exploration for self-awareness, incarcerated women learn to free their minds from their limiting situation. Examining the model through prison, Freirian, feminist methodologies affirms its significance/effectiveness as the essential first step for saying things differently, for liberation from oppression
Rattling the Cage: Incarcerated Men, Gender and the Construction of Maleness
This excerpt from Vanzant speaks to the purpose of this research with incarcerated males. Succinctly, the issue—Vanzant\u27s harmful actions /male criminal activity—is an age-old one with punishment as the antidote. This study, alternatively, chose to look at the issue from a learning perspective: men\u27s learning, outside of the academy, to gain insights into themselves, their being as men, and to take ownership for rerighting themselves (their words), with literature serving as the medium
