The many genetic complementation groups of DNA excision‐repair defective mammalian cells indicate the considerable complexity of the excision repair process. The cloning of several repair genes is taking the field a step closer to mechanistic studies of the actions and interactions of repair proteins. Early biochemical studies of mammalian DNA repair in vitro are now at hand. Repair synthesis in damaged DNA can be monitored by following the incorporation of radiolabelled nucleotides. Synthesis is carried out by mammalian cell extracts and (...) is defective in extracts from cell lines derived from individuals with the excisionrepair disorder xeroderma pigmentosum. Biochemical complementation of the defective extracts can be used to purify repair proteins. Repair of damage caused by agents including ultraviolet irradiation, psoralens, and platinating compounds has been observed. Neutralising antibodies against the human single‐stranded DNA binding protein (HSSB) have demonstrated a requirement for this protein in DNA excision repair as well as in DNA replication. (shrink)

The term “dualism” is used in quite divergent connotations across religious studies, sociology, theology, anthropology, and other academic fields. This paper characterizes the differing usages of the term, and uses them to explore the sometimes-converging and sometimes-orthogonal relationship between academic fields, with a focus on religious studies and the sociology of religion. I argue that although the two fields have mutually benefited from insights originating on either side of their divide—and thus converged in important ways—substantive differences remain. Their differing understandings (...) of “dualism” represents important theoretical and analytic divergence, and the justified critique of certain forms of dualism has been used to reject all versions of the concept, including some—here termed “embodied dualism” or “experiential dualism”—that remain analytically crucial to the study of social life generally and religion particularly.
