Human body

In this thesis an attempt is made to calculate the power absorbed in different parts of a human block model which is located in free space and is exposed to a plane electromagnetic wave. The moment method is applied to solve an integral equation which relates the incident field to the induced electric field in an arbitrarily shaped biological body. To obtain more accurate results, a numerical integration technique developed here has been used. The computations on the induced electric fields compare well with earlier work done in this area. It has been found that there is indeed heating of tissues outside the region of intended treatment in hyperthermia at 80 MHz.

The literature regarding biological motion suggests that people may accurately identify and recognize the gender of others using movement cues in the absence of typical identifiers. This study compared identification and gender judgments of traditional point-light stimuli to skeleton stimuli. Controlling for previous experience and execution of actions, the frequency and familiarity of movements was also considered. Watching action clips, participants learned to identify 4 male and 4 female actors. Participants then identified the corresponding point-light or skeleton displays. Although results indicate higher than chance performance, no difference was observed between stimuli conditions. Analyses did show better gender recognition for common as well as previously viewed actions. This suggests that visual experience influences extraction and application of biological motion. Thus insufficient practice in relying on movement cues for identification could explain the significant yet poor performance in biological motion point-light research.

This dissertation draws on feminist theory and ecofeminist philosophy to examine the connections between understandings of women and nature and the construction of pervasive conceptualizations and practices of childbirth. It also examines the relationship between conceptualizations of men and masculinity, culture and nature, and childbirth. In order to conduct such an examination, this study explores the dominant Western discourse around gender and childbirth. Specifically, the work aims to identify prominent characteristics and themes related to childbirth in both popular culture, such as Hollywood films (Knocked Up, The Backup Plan), documentaries (The Business of Being Born), birth guides, magazines, news articles, websites, and scholarly, medical and alternative healthcare discourse. This work seeks to consider how various conceptualizations of childbirth are used to legitimate, or, alternately, to undermine, patriarchal gender norms such as emphasized femininity and patriarchal (hegemonic) masculinity and, more generally, what ecofeminist philosopher Val Plumwood calls "master consciousness" (Val Plumwood 1993), a way of understanding the world that is reliant on an unjustifiably dualistic thinking and that is responsible for fostering social practices of domination. In particular, this work seeks to determine to what extent is our conceptualization of childbirth, and subsequent practice, based on potentially erroneous presumptions about the hierarchical division between the realms of culture and nature and masculinity and femininity? Perhaps most importantly, this dissertation sets out to consider the implications of alternative conceptualizations of childbirth emerging in the context of the natural birth movement. Specifically, I aim to determine whether or not these alternatives interpretations of childbirth counteract patriarchal gender categories and the culture/nature dualism.
