Item Observations on intermediary metabolism in the human forearm(1962) Rabinowitz, DavidTh.e energy mechanisms present in skeletal muscle have been extensively studied by biochemists using in vitro system s. (Per example see 1, 2, 3). By contrast, attempts to quantify skeletal muscle metabolism in situ — and thereby to establish the pattern of energy metabolism in use, rather than that which is potentially available — have been relatively Infrequent. While the human forearm is undoubtedly composed of a number of different tissues, by far its greatest bulk is skeletal muscle. Correctly used, it provides a readily accessible tool for the appraisal of skeletal muscle metabolism in situ. The material to be presented in this dissertation describes the results of studies of basal metabolism of skeletal muscle and adipose tissue in the human forearm in control subjects and in individuals in whom metabolism was altered either by obesity or by endocrine disease. The studies are based upon the application of, and strict adherence to the principle outline by Pick in 1870 (4).Item The relevance of trust and legitimacy for the introduction of credit rating agency regulation in South Africa: an application of modernity theory(2014) Rabinowitz, DavidThe 2007/2008 financial crisis and the role that credit rating agencies (CRA’s) played leading up to the crisis precipitated the introduction of CRA regulation worldwide. By using Giddens’s (1990. 1991) theory of modernity as a framework, this study explores the rationale for the introduction of CRA regulation in South Africa (the Credit Rating Services Act No. 24 of 2012), with a specific focus on trust and legitimacy. The findings in this study suggest that while the introduction of new regulation is a mechanism used to legitimise the capital system, it often has limitations and unforeseen consequences. This study used detailed interviews with some of South Africa’s leading experts on the credit rating industry to explain the reasoning for South African CRA regulation. Lastly, this thesis adds to the scant body of interpretive (and normative) research on the use of arms-length regulation in modern governance discourse, and it is also the first research to explore CRA regulation in the South African context.
