Item Gender Effects on Knee Loading and Prediction of Knee Loads Using Instrumented Insoles and Machine Learning(2024) Snyder, Samantha Jane; Miller, Ross H.; Shim, Jae Kun; Kinesiology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Women are more likely to experience knee osteoarthritis as compared to men, but the underlying mechanisms behind this disparity are unclear. Greater knee loads, knee adduction moment, knee flexion moment, and medial joint contact force, are linked to severity and progression of knee osteoarthritis. However, it is unknown if greater knee loads in healthy, young women during activities of daily living (sit-to-stand, stand-to-sit, walking and running) can partially explain the higher prevalence of knee osteoarthritis rates in women. Although previous research showed no significant differences in peak knee adduction moment and knee flexion moment between men and women, differences in peak medial joint contact force are largely unexplored. Women also tend to take shorter steps and run slower than men. It is unknown if these differences may result in greater cumulative knee loading per unit distance traveled as compared to men. Furthermore, knee loading measurement is typically confined to a gait laboratory, yet the knee is subjected to large cyclical loads throughout daily life. The combination of machine learning techniques and wearable sensors has been shown to improve accessibility of biomechanical measurements without compromising accuracy. Therefore, the goal of this dissertation is to develop a framework for measuring these risk factors using machine learning and novel instrumented insoles, and to investigate differences in peak and cumulative per unit distance traveled knee loads between young, healthy men and women. In study 1 we developed instrumented insoles and examined insole reliability and validity. In study 2, we estimated knee loads for most activities with strong correlation coefficients and low to moderate mean absolute errors. In study 3, we found peak medial joint contact force was not significantly different across activities for men and women. Similarly, in study 4, we found no significant difference between men and women in knee loads per unit distance traveled during walking and running. These findings suggest biomechanical mechanisms alone cannot explain the disproportionate rate of knee osteoarthritis in women. However, in future research, the developed knee loading prediction models can help quantify daily knee loads and aid in reducing knee osteoarthritis risk in both men and women.Item PLATONIC CO-PARENTING: A NEW LENS INTO THE UNFINISHED GENDER REVOLUTION(2024) Reddy, Shilpa; Chuang, Julia; Madhavan, Sangeetha; Sociology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)The aim of this dissertation is to investigate the extent to which platonic co-parenting (PCP), an alternative family form in which parenting is separated from romantic relationships and often also from coresidence, is creating and sustaining gender egalitarian parenting relationships. In other words, how gender egalitarian are these parenting partnerships? Using 32 in-depth semi-structured interviews with men, women, non-binary and trans people, who were at different stages of the PCP journey, I investigated the practice of platonic co-parenting by focusing on the motivations for people to choose the PCP path to parenting; and how they navigated gendered patriarchal norms in the process of becoming PCPs including division of household labor. I found two broad categories of people who were drawn to PCP: those who attempted to subvert hegemonic, heteronormative ideals of family and parenting; and those who attempted to reproduce these ideals. The subverters aspired to form gender egalitarian and equal partnerships whereas the reproducers desired/imagined the mother as the primary parent and the father’s role being closer to a sperm donor’s—a father figure as opposed to an involved father. Among the subverters, the realities of the division of labor once they had a child turned out to be far less gender egalitarian than they had intended as the pull of traditional gender norms was quite strong for both men and women. PCPs engaged in gendered boundary work to separate aspects of their family that fell in the transactional realm and those that fell in the intimate/sacred realm free of monetary or other exchanges. Framing certain activities (childbearing, breastfeeding, relocation, and parental leave) as intimate had the unintended consequence of creating inequality between the male and female co-parents. By using the language of altruism to naturalize their arrangements, PCPs intend to be seen as “real” families while leaving in place traditional cleavages of the gendered division of labor.Item They 'Boast of Dressing Like Gentlemen': Cross-Dressing, Print Culture, and Nineteenth-Century Gender Ideology(2024) Hemphill, Julia Kay; Lyons, Clare A; History; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Nineteenth-century gender roles were very strict but cross-dressing challenged these extremely binary roles, often being written about in different forms of print media. The press published stories about cross-dressing people in different ways depending on the actions they took in male attire. Soldier women cross-dressed and entered the military, but were not reprimanded for their decisions because their amount of time in male attire was perceived to be finite and because they were performing a service for their country. Women and male-presenting people who wore male attire and went into male workplaces, took wives, and became heads of household were highly reprimanded in the press in lengthy articles and short stories. Finally, women who wore the reform dress and liberated themselves from enslavement in male attire were spoken about in the press in two competing ways, with people supporting their transgressions and others not. Looking at the different ways that print media discussed these women and male-presenting people is important for looking at how gender roles were structured, and for understanding why powerful men were only threatened by certain cross-dressers.Item WOMEN IN ORANGE: HOW WOMEN IN PRISON ADAPT, NAVIGATE RELATIONSHIPS, AND MAINTAIN IDENTITY(2023) Philippon , Cassandra Nicole; Porter, Lauren; Ellis, Rachel; Criminology and Criminal Justice; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)The body of literature describing women’s prisons and the adaptations of women in prison largely overlook the role femininity plays in structuring life in the single-sex space of a women’s prison. Virtual, semi-structured interviews were conducted with fifty-six women housed at a women’s prison in Arizona. Participants described providing care for others and care for the self. Life in the prison was therefore structured primarily around care, which refers to a feeling of concern or interest, providing for the needs of someone, or paying close attention to doing something to avoid harm.Item “WHAT PERSONS, MASCULINE OR FEMININE”: EXAMINATIONS OF IDENTITY CONSTRUCTION AND QUEER POTENTIALITIES IN WESTERN MEDIEVAL EUROPE(2023) Taylor, Erin; Bianchini, Janna; History/Library & Information Systems; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)In this thesis, I argue that medieval people in Latin Europe had complex, overlapping identities and experiences of gender and sexuality that developed in their specific temporal and geographical contexts. The internal understandings of identities and the external expressions and interpretations of such identities are sites of historical possibility—and sources of potential inter-and intra-personal conflicts Medieval writings like Le Roman de Silence demonstrate how these identities could be constructed and expressed for literary and rhetorical purposes. Extant court cases, including those of John/Eleanor Rykener, Vitoria of Lisbon, and Katherina Hetzeldorfer, demonstrate the complexity of lived experiences of identity, and how deviation from accepted community and cultural norms could prove dangerous. It is impossible to assert such identities of gender and sexuality for historical figures of the medieval era with complete certainty, but the exploration of these identities is necessary for a fuller understanding and representation of the period and the people who lived throughout it.Item "I Have an Extra Level of Context That Some Reporters Don't Have": Journalistic Perspectives on the Role of Identity and Experience in the Production of More Equitable News Coverage(2023) Siqueira Paranhos Velloso, Carolina; Steiner, Linda; Journalism; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)In the summer of 2020, Alexis Johnson and Miguel Santiago, Black reporters at the Pittsburgh Post-Gazette, were removed from covering ongoing racial justice protests. The following year, Felicia Sonmez, a Washington Post reporter who had publicly identified herself as a survivor of sexual assault, was barred from covering stories about sexual misconduct. In both cases, management at their news organizations invoked a safeguard against bias as the reason behind the removal of the reporters from covering certain stories or beats. In other words, management feared that these reporters would not be able to perform basic journalistic duties because their proximity to the subject matter, whether through similar lived experiences or certain identity markers, would render them unable to relay a suitable and accurate account of events. However, the journalists in question protested their coverage bans by arguing that their identity- or experience-based connection to the issue would have been advantageous to their journalism. For example, Johnson said: “as a [B]lack woman, as a Pittsburgh native, as the daughter of a retired state trooper and a retired probation officer, it was a shame I wasn’t able to bring my background to cover this story.” In essence, the journalists argued that, rather than their proximity to the stories rendering them unable to produce proper accounts of events, their personal identities and lived experiences made them more capable of capturing the nuances required for adequate coverage. The purpose of this dissertation is thus threefold: first, it investigates journalists’ perceptions about the relationship between, and impact of, their personal identities and lived experiences and the reporting they produce. Second, it examines best practices journalists recommend to other journalists about covering issues or groups with which they don’t share an identity- or experience-based connection. Finally, it describes best practices journalists recommend to newsroom leaders for supporting journalists in producing more equitable and inclusive coverage. Through a textual analysis of 186 metajournalistic articles and 93 Twitter posts (“tweets”), this study found that journalists pinpoint a myriad of specific advantages they perceive reporting with an identity- or experience-based connection provides. As such, this dissertation advances literature on journalistic identity and role conception by demonstrating how journalists’ personal identities and experiences shape their professional values. It also argues that, by positioning this form of newsmaking as more equitable and legitimate than traditional “objective” reporting, journalists are constructing new conceptions of journalistic identity. This dissertation also contributes to literature on journalistic authority by showing that many journalists claim reporting with identity- or experience-based connections in fact makes them more authoritative interpreters of news. By asserting their roles as professionals who ultimately aim to produce accurate, factual reporting and resisting accusations of being activists rather than journalists, reporters also engaged in boundary work by increasingly placing reporting which embraces the subjectivity of the journalist within the bounds of professional journalistic practice. When making recommendations to fellow reporters for producing more equitable and inclusive reporting, the journalists featured in this dissertation called for a reconsideration of normative journalistic practices and recommended that their colleagues place equity at the forefront of every decision they make during the reporting process. The journalists’ recommendations to newsroom leaders demonstrate that producing equitable coverage goes beyond individual strategies that journalists can implement; change must also occur at the structural level. Establishing and enforcing new sets of journalistic policies at the newsroom level is a vital component of providing coverage that is fair and accountable to all communities. In describing how journalists are harnessing the tenet that knowledge is socially situated to advocate for new standards of news production, I also suggest feminist standpoint epistemology (FSE) as an operational framework of journalistic practice.This dissertation is a timely intervention into the ways journalists say their industry needs to change in order to better serve the needs of American audiences in the twenty-first century. The findings in this study have relevant implications for journalistic practice: they provide a clear roadmap for journalism scholars and practitioners for engaging in efforts to make journalism more equitable and inclusive.Item Essays on the Economics of Crime, Gender, and Health(2023) Ramirez Pierce, Elena; Goldberg, Jessica; Economics; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)In this dissertation I study the impacts of large government programs on crime and health outcomes. I also run an online experiment about the use of professional titles to elicit perceptions of experts cited in major news outlets and to test whether these perceptions vary across genders. In the first chapter, I examine the effects of large changes in cash availability on crime. South Africa has a large social safety net comprised of numerous cash transfer programs, called social grants, that are paid on a monthly basis. Prior to late 2018, these social grants were paid mostly in cash at grant disbursement locations called paypoints. Using a differences-in-differences (DiD) strategy, I analyze the effects of the temporary increase in cash availability on crime by comparing crimes on social grant payment dates in small geographical areas, police precincts, between areas with differing numbers of cash disbursement locations. The results suggest a small decrease in crime the day prior to social grant payments, and small increases the day of payments or the day after payments, depending on the empirical specification. These results are consistent with perpetrators potentially delaying their labor supply of crime until the widely publicized cash grant payment days, an anticipation effect, and increasing their labor supply of crime on or after payment days consistent with a loot effect, resulting from increased cash and purchased goods availability. Chapter two investigates whether there exists a credibility penalty for female experts compared to male experts when major news outlets forgo the use of professional titles, such as ``Dr." that serve as an information signal on the level of their training. Given the extensive literature on gender and racial bias in media reporting and professional and academic environments, the practice of abstaining from the use of professional titles may reinforce and even exacerbate these biases. In this co-authored analysis, we test for differential effects by conducting an online experiment that presented survey respondents with news articles holding constant content, but varying the gender and title of the cited experts and asked them to rate the expert's credibility. Our design enables between-subject and within-subject analysis. While we are able to detect a positive credibility effect of using professional titles, we are unable to distinguish a differential credibility impact across gender. Finally, in chapter three I estimate the effects of a large-scale national physician provision program in Brazil on birth outcomes. Given the risk to mothers of injury and disease associated with childbirth that may affect the health of the newborn, as well as the myriad of complications that may arise that could threaten the health of the fetus, increasing access to and quality of medical care may have substantial effects on birth outcomes. The Mais Medicos Program (PMM) focused on equalizing physicians per capita as well as generally increasing the number of physicians across the country. Beginning in late 2013 and an executive branch initiative, the program placed almost 20,000 physicians by 2016, predominantly from Cuba, throughout the country. Using vital statistics data of the universe of births in Brazil from 2006 to 2017, I estimate the effect of increasing the supply of primary care physicians on birth weight using both a differences-in-differences and an instrumental variables approach. I find that PMM resulted in higher average birth weight for children throughout Brazil. However, I find no improvement on the incidence of low birth weight or any weight effects for those living in rural parts of the country. Hence, these results imply PMM did not affect the most vulnerable pregnancies.Item The Home We Can Never Leave(2023) Richardson-Deppe, Charlotte R; Keener, Cy; Art; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)Growing up, I performed aerial arts in a circus. In the circus, a web of interdependence keeps you off the ground—the tightness of your grip, the strength of your friend holding you up, the trust in an apparatus to hold your weight. In my own body now, I feel the residual stretch, tension, and ache the circus left in me—remnants of bodies pushing through pain, defying gravity to hold one another up. Via soft sculpture and performance, I negotiate the body as a site of both liberating autonomy and confining oppression.Item Essays in Gender and Development(2023) SIVARAM, ANUSUYA; Goldberg, Jessica; Economics; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)This dissertation consists of three essays at the intersection of gender and economics in developing countries. In chapter 1, I study the economic implications of a particular cultural practice: cousin, or consanguineous, marriage. One sixth of all marriages in Egypt are between first cousins, but there are important differences in the characteristics of individuals who select into such relationships relative to those who marry non-relatives. To measure the causal impact of the practice on socioeconomic outcomes abstracting from selection, I instrument for the probability of marrying a cousin using exogenous variation in family structure, and use weak instrument robust methods to estimate parameters and evaluate statistical significance. I find that individuals who marry a cousin because of exogenous attributes of their natal family structure are further in age from their spouse, predominantly driven by older men marrying cousins. I also find that women married to cousins receive higher levels of marital transfers that give them bargaining power within their marriages, likely as compensation for their spouse's attributes. This contrasts to patterns for those who select into cousin marriage; those individuals are younger at the time of marriage, match with partners closer to their own ages, and have no differences in the level of marital transfers exchanged. The contrast between OLS and IV results suggests that selection into cousin marriage may be motivated by anticipation of not matching on the wider marriage market, credit constraints, or the desire to consolidate property within the extended family. In chapter 2, I present baseline statistics from an experiment which examines the impact of random job offers on women's experiences of intimate partner violence in Bangladesh. This paper build on a larger study which aims to increase women's labor force participation and use of mobile money services. I collect supplementary data on women's experiences of intimate partner violence, men and women's agreement with conservative social norms, and second order beliefs regarding their community's sanction of intimate partner violence. I validate survey measures of intimate partner violence with a list randomization elicitation. I also present results from two incentivized decisionmaking activities conducted at baseline. I specify the outcomes I plan to test once endline data is available, as well as the econometric specifications I will use. Finally, I present power calculations using baseline data to determine the smallest effect sizes I can detect. Finally, in chapter 3, I study the impact of an exogenous negative shock to labor demand for female migrants within Bangladesh. I use a difference in differences strategy and compare outcomes between districts that have a history of sending migrants with those that do not, before and after the shock. I find that migrants respond to the initial shock and return to their households rather than remain unemployed in Dhaka, and that at least some of these women marry. I see no decrease in the level of investment in children's human capital, which suggests households do not revise their perceptions regarding the returns to education, and have access to other tools to smooth consumption. Finally, I see no changes in the daily agricultural wage rate for women in the years after the shock. I lack data on several important margins of adjustment which would allow us to discern the mechanisms behind the effects.Item Understand You Are Going To Deal With Hardships That Women Deal With In The Civilian World, Kind Of Like On Steroids”: Air Force And Army Women Veterans’ Perceptions Of The United States Military(2023) McDermott, Victoria Marie; Anderson, Lindsey B; Communication; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)The United States military (USM) is a totalistic and hegemonically masculine institution that leaves lasting effects on former members sense of self and identity. The performance of gender by individual members, and the gendered nature of the institution itself make it a challenging profession for those categorized into the subordinate gender to navigate and succeed. Using feminist standpoint theory, this dissertation explores women’s perspectives of their experiences during and after military service to better under the role of gender on institution-public relational meaning making. Findings demonstrate that gender performed, on individual and institutional levels forms gendered relationships to the institution that have long term effects on individuals willingness to engage with the institution. From the findings identified, theoretical extensions and practice implications, as well as recommendations for the USM to improve its relationships with women veterans are suggested.
