Parental Instincts: The Neurological And Biological Factors Associated With Parenthood, Jared Reeder

Undergraduate Honors Theses

The following project involves a systematic review of the scientific literature on neural and biological changes of mothers and fathers in parenthood. Until very recently, little scientific research was devoted to studying how bearing children affects a man or woman’s long-term biology. Over the last twenty years, studies of neuroplastic changes in new mothers show specific neural mechanisms responsible for altering the behaviors of mothers during and after pregnancy. These changes in neuroplasticity alter behavior in such a way that led to mothers requiring less sleep and being more prone to hearing the cries of their children. In addition to …

Seeing Children’S Futures Through Rose Colored Glasses: Does Optimism Bias Toward Reproduction Discourage Anti-Natalism?, Faith L. Brown

Dissertations

In order to examine the possibility that individuals continue having children and holding positive views toward reproduction regardless of how much their future children might suffer because of an optimism bias, I conducted two experimental studies examining the effect of optimism manipulation on people’s opinions of anti-natalism, the position that it is morally wrong for individuals to reproduce. In Study 1, participants received an optimism (v. pessimism or control) manipulation about either themselves or a future child before being asked to read an essay about anti-natalism and a control essay having to do with parents being involved in school …

Empowerment As A Birthright: Exploring The Power Of Informed Choice, Delaney Elizabeth Reece

WWU Graduate School Collection

Discussion of medical practice as a cultural experience is essential in understanding the disparities between biomedicine medical practice and evidentiary reports without medical intervention during childbirth and delivery such as the use of a midwife. Research, such as interviews, done about birth and birth experience may be able to highlight an individual's experience with these disparities. The history of birth care in the United States and the greater capitalist culture at large have greatly influenced the culture of birth today. Capitalist cultures are not consistent in every hospital or birth experience but remain in every hospital. They therefore also impact …

Energetic Tradeoffs, Infection, And Immunity In Wild Chimpanzees Of Uganda And Tanzania, Sarah Renee Phillips

Anthropology ETDs

Infectious disease is a primary source of mortality for most mammal species, but scientists have little understanding of factors driving variation in infection and immunity between individuals, populations, and species in the wild. Life history theory provides an evolutionary framework for delineating distribution of available energy to competing physiological demands, including growth, reproduction, and maintenance. Early life reproduction should be favored over late life survival, but, in long-lived species, reproductive success is strongly tied to survival to old age. Slower pace of reproduction could allow investment in immunity, reducing risk of morbidity and mortality to infectious disease. Additionally, several host …

Disparities In Access To Assisted Reproductive Technology Among Hispanic Women In The United States, Madison Gallagher

Honors Thesis

Infertility is a health problem that affects approximately 7 million women in the United States (Ethics Committee of the American Society for Reproductive Medicine, 2015). Due to the high costs of reproductive medicine and infertility treatment, these services tend to be expensive and have limited accessibility without full insurance coverage. Emerging literature outlines the disparities in access to proper treatment for reproductive complications. These existing studies highlight that many minority populations in the United States experience increased challenges regarding access to reproductive medicine and infertility treatment. Among these minority groups are Hispanic women, who are more likely to require reproductive …

Effects Of Long-Term Variation In Temperature On Reproductive Phenology In A Population Of Eastern Bluebirds (Sialia Sialis), Paul Pleiman

Graduate Theses and Dissertations

This study investigates the relationship between multiple temperature variables, to include annual and pre-lay date temperatures with first-egg and mean first-egg lay dates of the eastern bluebird at the Warner Parks in Nashville, Tennessee, USA. Data is collected by citizen scientists for the Eastern Bluebird Nesting Box Project while visiting artificial nest boxes throughout the park and recording observations made during the breeding season. Temperature data is retrieved from the Northwest Alliance for Computational Science and Engineering’s Parameter-elevation Regressions on Independent Slopes Model (PRISM) Climate Group, based at Oregon State University. The analyses showed no correlation between annual or pre-lay …

Practical Problems And Moral Discourses: An Ethnography Of Breastfeeding, Tara Ann Gallagher

Theses and Dissertations

Universal and bioactive, breastfeeding is a burgeoning biocultural topic because it incorporates biological and social determinants of human behavior. The topic has amassed media attention framed as part of a bigger imagining of motherhood as an idealized state directed at the female body’s performance. This paper questions media and public policy’s role in the dissemination of culture and the symbolic value of breastmilk. This study examines breastfeeding discourses through the lens of an American, mostly white, Midwestern middle-class social structure. Using participant observation data of two postpartum support groups and semi-structured interviews with six primiparous mothers, my data suggests that …

Associations Among Beef Cattle Genotypes, Neospora Caninum Infection, And Reproductive Performance, Ryan James Page

Graduate Theses and Dissertations

Reproductive performance is crucial for sustained financial success in the beef cattle industry. This dissertation includes a population study that quantified the incidence of Neospora caninum infections in the central region of the United States and tested its relationship with reproductive performance in beef cattle. Trial one of that study concluded that 6.9% of open, replacement heifers (n = 1306) tested seropositive. The second trial in that project found that 9.6% of the breeding age females (n = 500) tested were seropositive for Neospora caninum; and that state in which the cattle lived and age impacted (P < 0.05) infection rate. Breed composition, number of farm dogs on the ranch, and use of total mixed rations were not associated (P > 0.1) with seropositive …

“I Felt So Untrustworthy Of My Ability To Get Pregnant”: Women’S Embodied Uncertainties And Decisions To Become Pregnant, Theodora K. Hurley

Honors Projects

This paper identifies “embodied uncertainties”—possibilities of aging and infertility lodged within the body—as informing women’s conceptualizations of their reproductive bodies and their decisions about and approaches to getting pregnant. Using data from semi-structured interviews with a small sample of highly educated, professional, white women who had given birth within 18 months prior, this paper argues that (bio)medicalized risk discourses and neoliberal logics of responsible choice-making lodge uncertainty and the possibility of failure within women’s reproductive bodies. As they attempt to reconcile childbearing with professional and financial constraints, women may identify their bodies as laden with embodied uncertainties and may subsequently …

Stratified Access On The Border: Examining Experiences Of Reproductive Care, Maralyn Doering

Open Access Theses & Dissertations

Patient care experiences shape and affect the way that patients perceive and contextualize health care (Koenig 2011). Prior care experiences can change how patients choose to receive care in the future. In Texas, reproductive health care research has primarily focused on troubling trends in reproductive health care outcomes. This can be noted by the high cervical cancer rate (CDC 2019), the high unintended pregnancy rate (Kost 2015), and the limited access to reproductive care, particularly preventative care (Hopkins et al. 2015). The focus of this research has been on structural barriers, such as funding cuts (White et al. 2012), barriers …

Effects Of Toxic Fescue Exposure On Vaginal Microbial Communities Of Crossbred Beef Cows, Abby Ratton

Animal Science Undergraduate Honors Theses

The consumption of toxic fescue by beef cattle results in several adverse physiological effects such as reduced reproductive success, severe vasoconstriction resulting in hoof sloughing, low body condition scores, hyperthermia, decreased prolactin levels, and reduced hair shedding. The purpose of this study is to characterize bacterial community of the reproductive tract as a potential predictor for toxin exposure. One-hundred fall-calving crossbred cows were allocated to graze Toxic (Toxic: n=50) or Novel (Novel: n= 50) fescue pastures for five months (March-August). Treatments were blocked by sire breed (Charolais or Hereford) and by parity (first, second, third). Animals rotated pastures biweekly and …

An Analysis Of The Impact Of Birthing Practices On Long-Term Health And Reproductive Outcomes From The 1970 British Cohort Study: Insights From Evolutionary Theory, Elizabeth Turner

Boise State University Theses and Dissertations

A wealth of research has been amassed and continues to grow through efforts to understand the complex nature of the relationship between the colonization and development of the human gut microbiota, its influence on the development of the immune system, and its role in both health and disease. Since previous research has demonstrated early life conditions can influence the colonization and development of the human gut microbiota, it is critical to understand how circumstances around the birthing process affect long-term outcomes beginning at this crucial stage in our development. Using the 1970 British Cohort Study, this thesis examines the relationship …

The Vaginal Microbiome Related To Reproductive Traits In Beef Heifers, Maryanna Wells Mcclure

Graduate Theses and Dissertations

The greatest impact on profitability of a commercial beef operation is reproduction. In the human vaginal microbiome, dominance by Lactobacillus is a sign of reproductive health and fitness. In other species (non-human primates and ewes), Lactobacillus is found in low amounts and dominators of these microbial communities are considered to be pathogenic in humans. In beef heifers, little is known about the vaginal and fecal microbiota with respect to their relationship with fertility. To this end, we followed heifers through gestation to examine the dynamics of vaginal and fecal microbial composition throughout pregnancy.

Heifers were exposed to an estrus synchronization …

Women’S Role In Their Reproductive Process: The Effects Of Authoritative Knowledge And Biomedical Interventions On The American Birth Experience, Shannon Sheffey

Masters Theses

The primary focus of this study is to analyze the effects of authoritative knowledge and biomedical interventions on women’s role within their reproductive process as it occurs within the US.I explore the technological advances surrounding childbirth practices within the United States and how through this technology, biomedical forms of authoritative knowledge of birth practices have developed and how these changes have benefitted as well as hindered women. Through interviews and interactions with mothers and pregnant women I evaluate how medical interventions emotionally and physically affect women; evaluate the necessity of increasing technological interventions as opposed to low technology midwifery assisted …

Managing Sociality Of A Captive Female Bornean Orangutan From Breeding To Post-Partum At The Smithsonian's National Zoo, Marie Vergamini

Theses and Dissertations

The Association of Zoos and Aquariums’ Orangutan Species Survival Plan® aims to maintain 100 Bornean orangutans (Pongo pygmaeus) in captivity. Because investment in breeding these lineages is high, properly managing sociality of potential mothers is essential. This study assessed how behaviors of a captive breeding female at the Smithsonian’s National Zoo changed from pre-gestation through the offspring’s sixth month of age to improve breeding recommendations.

The infant Bornean orangutan was born September 2016. Results indicate that during breeding, the mother socialized most with two adult females. During pregnancy, the pregnant female socialized in less energy-consuming ways, i.e. grooming. …

Consequences Of Developmental Lead (Pb2+) Exposure On Reproductive Strategies In Drosophila, Elizabeth Kathleen Peterson

Legacy Theses & Dissertations (2009 - 2024)

Anthropogenic lead (Pb) pollution is ubiquitous in the environment and a risk factor for both human and wildlife health. Pb exposure has the potential to alter reproductive strategies with respect to mate choice and reproductive output. This could be especially deleterious if these changes disrupt adaptive behavioral and reproductive life history strategies. Therefore, the overall aim of this body of work was to examine the consequences of developmental Pb exposure on reproductive strategies, using Drosophila melanogaster as a model system. In all experiments, D. melanogaster were reared from egg stage to adulthood in either control or leaded medium and were …

A Mindfulness-Based Stress Reduction Psychoeducational Program In Postpartum Support Groups, Marina Pesserl

Walden Dissertations and Doctoral Studies

Postpartum Depression (PPD) affects 15% of women after childbirth. Its etiology includes psychoneuroimmunologic factors with long-lasting postpartum stressors that lead to allostatic overload. Using mindfulness-based stress reduction (MBSR) for PPD has not yet been studied. Addressing this literature gap, the potential benefits of including an 8-week MBSR component based on Beck's theory of PPD at support groups were examined in this phenomenological study based on a sample of 10 women and 2 group facilitators. Purposes of the study included describing the experience of PPD and the MBSR program, identifying the stage of behavioral change of the participants, and describing the …

Defying Mandatory Motherhood: The Social Experiences Of Childfree Women, Braelin E. Settle

Wayne State University Theses

Research suggests motherhood is central to a woman's adult identity. In 2000, however, almost twice as many women ages 40-44 were childless than in 1980. Scholarship points to the social, economic, and attitudinal factors shaping the dramatic increase in the number of childfree women, many of whom are white, educated beyond high school, and upper-middle class. This qualitative case study focuses on the growing social phenomenon of childfree women in the United States. Using in-depth interviews, I examine the reasons behind women's decisions to remain childfree and the experiences of being childfree in their everyday lives. I focus on the …

Fertile Lands And Bodies: Connecting The Green Revolution, Pesticides, And Women’S Reproductive Health, Sarah M.K. Cycon

Pitzer Senior Theses

Environmentalists, social scientists, and economists have long critiqued the enduring impacts of the Green Revolution’s diffusion of agricultural technologies throughout the Global South. However, largely missing from the myriad analyses is the relationship between those technologies, namely pesticides, and health outcomes. This thesis explores the social and biological mechanisms through which excessive pesticide use culminated into adverse reproductive health outcomes for rural women in the Global South. Drawing together the history of the Green Revolution’s use of DDT, its social and economic impacts, and the biology of pesticide contamination in women’s bodies exposes how the Green Revolution situated women in …

Rock-A-Buy Baby: Consumerism By New, First-Time Mothers, Sara Afflerback

Electronic Theses and Dissertations

Rock-a-Buy Baby: Consumerism by New, First-Time Mothers, is the first known sociological exploration of need-based consumption for babies, despite the baby gear industry being a $6-billion-dollar business (whattoexpect.com). Data stemmed from qualitative, semistructured interviews with new, first-time mothers (3 months – 1 year postpartum) conducted within participants‘ households. The insights gained from the present study tell us a great deal about the ―needs‖ that predominantly white, middle-class mothers socially constructed in anticipation of their first child, and the consumptive behaviors used to accomplish these "needs." Respondents had turned to similar resources (other mothers, online forums, consumer reports, books, magazines, etc.) …

State Regulation Of Assisted Reproductive Technology, Jonathan J. Morgan

Theses and Dissertations

State regulation of assisted reproductive technology (ART) has been occurring since the inception of earlier technological advances such as artificial insemination to aid human reproduction. I provide a brief overview of the current regulation of ART in the U.S. and the literature on state regulation. Unlike previous studies of ART regulation which use content analysis or case studies of individual state laws I estimate ART regulation for the entire U.S. by using a series of random effects logistic regression models for the time period 1995-2006. To my knowledge this is the first quantitative analysis of ART regulation. I test the …

Reproductive Biology Of Mouse And Dwarf Lemurs Of Eastern Madagascar, With An Emphasis On Brown Mouse Lemurs (Microcebus Rufus) At Ranomafana National Park, A Southeastern Rainforest, Marina Beatriz Blanco

Open Access Dissertations

This dissertation investigates reproductive schedules of brown mouse lemurs at Ranomafana, using intensive trapping techniques. The reproductive condition of female mouse lemurs was recorded on the basis of vaginal morphology, vaginal smears, body mass gain profiles and nipple development. Testis size was measured in males throughout the reproductive season. The timing of the first seasonal estrus was determined in frequently captured females over multiple years and it showed individual periodicities close to 365 days, consistent with endogenous regulation and entrainment by photoperiod. The timing of estrus did not correlate with female age or body mass. Males showed testicular regression during …

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 …

Self-Esteem, Self-Efficacy And Gender In Social Class Reproduction, Spencer L. James

Theses and Dissertations

The observation that middle class parents tend to have middle class children is rather obvious. Why this is so has been the subject of less research than the fact that it is so. Using the National Survey of Families and Households (NSFH), I employ theories about social class reproduction to examine and evaluate a model that scrutinizes the influence of self-efficacy and self-esteem on college completion or current enrollment and investigate gender differences. I find that self-esteem and self-efficacy play a vital role in social class outcomes. However, I find no evidence of gender differences in the social class reproduction …

Reproductive Experience And Aging : Possible Neuroprotective Effects Of Motherhood, Jessica Dawn Gatewood

Master's Theses

Hormonal fluctuations associated with pregnancy and post partum periods create significant changes in the brain and behavior in female rats. Animals were tested in a land version of the Morris Water maze for three days at 6, 12, 18 and 24 months. At the ages of 12, 18, and 24 months animals were also tested in the same maze using a reversal task. At the conclusion of the study brains were analyzed for Amyloid Precursor Protein (APP) to determine the amount of neurodegeneration among the groups. Multiparous animals showed significantly superior performance , followed by primiparous animals, and nulliparous animals …

The Concept Of Brahmacarya, Evelyn Vrat

University of the Pacific Theses and Dissertations

Contemporary civilization of the western world represents a combination of material development and moral degeneration, Value is measured in 'space' not in 'spirit'. Antecedent to the complications of life with its sufferings) 'fiddlers fees' and disillusionments, how very few realize that true pleasure is not in having, but in being? Fewer still are those whose feelings, thoughts and actions are conscious, aware, self-chosen and self-directed. More often than not, introspection reveals that most are not masters, but the mastered, victims of moods and conflicts...

However, deep dissatisfaction with life as it appears to be and with the individual's adaption to …
