Revisiting Mary O’Brien – Reproductive Consciousness and Liquid Maternity
This research note examines feminist theory from socialist feminism through the post-structural turn associated with thinkers like Foucault, Derrida and Butler to neo-materialism, this last noted for its emphasis on the body's materiality as opposed to the subject as a socially constructed or merely linguistic practice. Tracing these theoretical developments is contextualized with respect to theories and concepts such as feminist standpoint theories of epistemology, historical materialism and Baumann's "liquid modernity". I ask: have we lost sight of the strength of feminist structuralism - particularly the effects of capital - in order to accommodate multiple and complex subjectifications associated with gender? Mary O'Brien's reproductive consciousness, her argument that women's consciousness is fundamentally shaped through the different moments related to reproduction, is re-examined in light of recent developments in egg donation and surrogacy. This is not intended as an exercise in romantic longing for some sort of utopian society where femininity is venerated. Rather, it is an exploration of the potential for reproductive consciousness to guide political responses to contemporary problems raised by new reproductive technologies that combine capital and gender in a single dialectic
The turbulent single-phase forced convection heat transfer and pressure drop characteristics of circular ducts containing swirl-row inducers or pall rings
The heat transfer and pressure drop characteristics of tubes
containing either Pall rings, or helical (180°) strips of metal, were
studied experimentally. Tests were performed with water in the Reynolds
number range of 11000 to 104000, approximately.
Rotameters were used to measure the volumetric flowrate of the
water. The effect of fluid temperature on this measurement was
determined.
The insertion of a continuous length of Pall rings into a tube
increases the Nusselt number and pressure drop by factors of 1.5 and 15.
(These factors are relative to the empty tube over the same flow range).
Smaller increases were obtained while using rings that were equidistantly
spaced along the tube. [Continues.
Women and Reproductive Technologies
A sociological and historical study of the development of reproductive technologies, this book focuses on key technological developments through a biomedicalization lens with special attention to gender. Using in vitro fertilization (IVF) as a hub, it critically examines the main areas of related socio-technical developments: reproductive science, birth control, animal husbandry, genetics and reproductive medicine. Employing a critical framework to illuminate dominant discourses, the book also highlights examples of social resistance, as well as contradictory responses to new reproductive technologies. Over eight chapters, the author examines the social history of reproduction and sexuality, reproductive technologies from old to new and debates surrounding new reproductive technologies and genetic engineering. Women and Reproductive Technologies pays close attention to the interconnections between the business of reproduction (and replication industries), the sociality of reproduction (including reproductive justice) and what are considered the technologies themselves. As such, it constitutes essential reading for students and researchers in the fields of sociology, health studies and gender studies interested in the current state of human reproduction
The Masculinized Work of Energy Development: Unequal Opportunities and Risks for Women in Pennsylvania Shale Gas Boomtown Communities
The proliferation of unconventional shale gas development has revived scholarly interest in the impacts of rapid industrial development on communities, schools, policies and politics, public health, the environment, and economic growth. However, with few exceptions, close examinations of the gendered structure of opportunity within areas experiencing rapid shale gas development have largely been absent from this literature. This article uses key informant interview data from low income men and women, as well as from social service providers within Pennsylvania communities heavily affected by shale gas development. In contrast to assertions that shale gas development will yield broad-based economic development impacts for the region, the experiences of the participants in this study suggest a more segmented economic opportunity structure coupled with the creation of new gendered economic and social vulnerabilities as class and gender intersect to create decreased economic opportunities and increased social vulnerabilities for low-income women
Open-Ended Evolutionary Robotics: an Information Theoretic Approach
This paper is concerned with designing self-driven fitness functions for
Embedded Evolutionary Robotics. The proposed approach considers the entropy of
the sensori-motor stream generated by the robot controller. This entropy is
computed using unsupervised learning; its maximization, achieved by an on-board
evolutionary algorithm, implements a "curiosity instinct", favouring
controllers visiting many diverse sensori-motor states (sms). Further, the set
of sms discovered by an individual can be transmitted to its offspring, making
a cultural evolution mode possible. Cumulative entropy (computed from ancestors
and current individual visits to the sms) defines another self-driven fitness;
its optimization implements a "discovery instinct", as it favours controllers
visiting new or rare sensori-motor states. Empirical results on the benchmark
problems proposed by Lehman and Stanley (2008) comparatively demonstrate the
merits of the approach
