Contradictions in power, sexuality, and consent: An institutional ethnography of male neonatal circumcision

In this dissertation I examine the routinization of prophylactic neonatal male circumcision in hospital settings in New England. Using the methodological framework of Dorothy E. Smith\u27s (1987) Institutional Ethnography, I study the ways in which institutionalized policies and processes regarding this procedure intersect in the lives of expecting parents and parents, as well as with those in the medical community. ^ I focus specifically on medical professionals and parents who interact both directly and indirectly in order to challenge or maintain a uniquely American tradition of male neonatal circumcision. In order to understand the attitudes and opinions of these different groups of people, including anti-circumcision activists, I have used a multi-method approach that combines an analysis of questionnaires, interviews, and ethnographic fieldwork in two hospital settings. During my research, I investigate the ways in which authority is maintained and resisted within hospital settings regarding male circumcision, and how the informed consent process is actually negotiated between parents and medical professionals. This dissertation contributes to sociological literature on organizational processes involving discourse, institutional authority, and the informed consent practices as they are experienced and regularly negotiated by healthcare providers and parents.

Liver and gallbladder uptake of ICG.

<p>a) Optoacoustic images through the liver. Grayscale image (left) showing anatomy and ROIs for liver (red) and gallbladder (yellow) analysis. b) FCSI image: fluorescence from ICG overlaid in green on color photograph of cryosection of a mouse sacrificed 10 minutes after injection, showing signal in the liver and gallbladder c) Plot of the signal increase in the liver ROI at 800 nm during single wavelength imaging of the ICG injection. Oscillations are mainly due to breathing motion. The scale is normalized to the maximum value. d) Specific (unmixed) signal from ICG after injection in the liver (black) and gallbladder (blue) ROIs. Each curve is normalized to its own maximum value.</p
