The ‘redefinition of death’ debate: Western concepts and western bioethics

Biomedicine is a global enterprise constructed upon the belief in the universality of scientific truths. However, despite huge scientific advances over recent decades it has not been able to formulate a specific and universal definition of death: In fact, in its attempt to redefine death, the concept of death appears to have become immersed in ever increasing vagueness and ambiguity. Even more worrisome is that bioethics, in the form of principlism, is also endeavouring to become a global enterprise by claiming neutrality. It appears that the discourse within both disciplines have similarly manipulated the boundaries of death to include the “dying”. This paper argues that the redefinition of death debate in biomedicine reveals a concept of personhood which is profoundly western in origin and which is in accordance to the concept adhered to within principlism. Biomedicine and bioethics do not appear to acknowledge the limitations of their own world view and hence lack an understanding of their applicability and appropriateness in diverse social and cultural contexts; a situation which adds credence to claims as to the hegemonic and imperialistic nature of all such global enterprises.

Predicting face similarity judgements with a computational model of face space

Current models of face representation involve the notion of a high-dimensional face space. Computational models of face space based on principal components analysis (PCA) have been successfully used to predict human judgements of face sex or race. In this work the capability of PCA-based face spaces to predict human judgements of face similarity is examined. Three different paradigms were used. In Experiment 1 subjects learned face-name associations for 18 faces and identified these faces on tachistoscopic presentation. The number of confusions was used as a measure of face similarity. In Experiment 2 the same subjects subjectively rated the similarity of all 153 possible face pairs. In Experiment 3 reaction time to identify a face in an odd-man-out task was measured as an index of face similarity. These empirical measures were correlated with distance of the faces in PCA-based spaces of different dimensionalities. For Experiments 1 and 2 these correlations were highest for one-or two-dimensional face spaces (r=−0.27 vs. −0.28). For Experiment 3 the correlation was highest for a space consisting of 13 dimensions (r=−0.51). Thus PCA-based spaces seem capable to predict human similarity judgements to some extent. Possible reasons for the differences in predictability between paradigms are discussed.     

Single-gender group psychotherapy: A “women's group” for adolescent inpatients

This paper describes an attempt at forming and conducting a unique single-gender psychotherapy group with severely disturbed female adolescents on a long-term, psychotherapeutically oriented co-ed inpatient unit. The focus of this group was assisting the female patients in negotiating the tasks and conflicts specific to their gender and developmental stage. The therapeutic approach and the role of female coleaders are described, emphasizing particular modifications made to meet the needs of this group. Clinical examples are offered to high-light salient group themes of identity formation and separation and individuation. Finally, group therapeutic factors specifically enhanced by single gender membership are discussed and observations regarding the group/milieu interface are explored.
