Contractions Or Constructions: A Content Analysis Of Birthing Facilities In Miami, Florida, Shameka Thomas

Sociology Theses

Numbers of caesarean sections, epidurals, and other forms of medical interventions for birthing are rising in the United States healthcare industry. One possible reason is the medicalization of birthing and labor techniques. Another potential reason is the increasing distinction between laboring in a hospital versus laboring in the home or an independent birthing center. The dominance of the medical model of birthing has led to social constructions of birthing that divide women by diagnosis, into either high-risk or low-risk prenatal categories, further perpetuating the medical model’s power to marginalize the midwifery model.

Forty percent of U.S. births are financed by …

Neural Regulation Of Sexual Solicitation In Female Syrian Hamsters: Role Of Oxytocin, Luis A. Martinez

Neuroscience Institute Dissertations

In most animal species, reproductive success depends critically on precopulatory or solicitational behaviors that occur prior to mating. The specific sensory systems and behavioral strategies employed in precopulatory behaviors vary across species; in all cases, however, animals must be able to identify potential mating partners and solicit sexual interest. Female Syrian hamsters (Mesocricetus auratus) engage in multiple forms of precopulatory behaviors that are preferentially expressed to males or their odors, including vaginal scent marking and sexual odor preference. Conspecific odors relevant for precopulatory behaviors are processed by a network of forebrain areas that includes the bed nucleus of the stria …

From No Hope To Fertile Dreams: Procreative Technologies, Popular Media, And The Culture Of Infertility, Evelina W. Sterling

Sociology Dissertations

Throughout history, both popular and scholarly literature depicted infertility as a devastating experience in a woman’s life. Infertility was unbearable, filled with stigma, and a perpetual state of conflict between those who cannot have children and the rest of the world who can. Until recently as treatments for infertility developed, families assumed childlessness as hopeless. While the process of overcoming infertility is still arduous, unpleasant and unpredictable, many options are available today to overcome infertility and have children. As a result, the portrayal of involuntary childlessness and infertility especially by popular media, changed significantly over the years. Current procreative technologies …

Not Trying: Reconceiving The Motherhood Mandate, Kristin J. Wilson

Sociology Dissertations

Infertile and childless women think about, live with, and defend their status as mothers and as nonmothers, arguably more so than other women for whom motherhood comes about accidentally or relatively easily in accordance with a plan. Within this group of infertile and childless women are those who are otherwise socially marginalized by factors like class, race, age, marital status, and sexual identity. This dissertation asks about the ways in which marginalized infertile and childless women in America make sense of their situations given the climate of “stratified reproduction” in which the motherhood mandate excludes them or applies to them …

The Posterior Bed Nucleus Of The Stria Terminalis Mediates Opposite-Sex Odor Preference In Male Syrian Hamsters (Mesocricetus Auratus), Laura Elizabeth Been

Psychology Theses

In Syrian hamsters, social behavior is mediated exclusively by chemosensory cues and circulating gonadal steroid hormones. Where these two signals are processed in the brain is unknown, but the posterior bed nucleus of the stria terminalis (pBNST) has been suggested as a candidate site. Therefore, we tested male hamsters’ preference for opposite-sex odors following excitotoxic lesions of the pBNST. Lesions of the pBNST (pBNST-X) eliminated male hamsters’ preference for opposite-sex odors. Furthermore, pBNST-X males spent significantly less time investigating female odors than clean odors and significantly less time investigating female odors than control males did. Lesions of the pBNST did …

Temperature-Dependent Sex Determination In Manouria Emys Emys, The Asian Forest Tortoise, Sherri Ann Emer

Biology Theses

Captive husbandry programs in zoos have documented nesting behavior and have successfully hatched Manouria emys emys, but data on sex determining mechanisms and sex ratios are absent. A total of 30 M. e. emys eggs were artificially incubated at five different temperatures in constant humidity. Mean incubator temperatures were 24.99°C, 25.06°C, 27.18°C, 28.00°C, and 30.79°C. Incubation duration ranged from 60 days to 92 days, and hatching success was 50%. Sex determined by histology and laparoscopy resulted in male differentiation at low temperatures (24.99°C, 27.18°C) and female differentiation at high temperatures (30.79°C). Pivotal temperature was estimated to be 29.29°C. The following …
