Biophysics, rockets, and the state: the making of a scientific discipline in twentieth-century China
Description
This study takes biophysics--a relatively new field with complex origins and contested definitions--as the research focus and investigates the history of disciplinary formation in twentieth-century China. The story of building a scientific discipline in modern China illustrates how a science specialty evolved from an ambiguous and amorphous field into a full-fledged academic discipline in specific socio-institutional contexts. It focuses on archival sources and historical writings concerning the constitution and definition of biophysics in order to examine the relationship between particular scientific styles, national priorities, and institutional opportunities in the People's Republic of China. It argues that Chinese biophysicists exhibited a different style of conceiving and organizing their discipline by adapting to the institutional structure and political economy that had been created since 1949. The eight chapters demonstrate that biophysics as a scientific discipline flourished in China only where priorities of science were congruent with political and institutional imperatives. Initially consisting of cell biologists, the Chinese biophysics community redirected their disciplinary priorities toward rocket science in the late 1950s to accommodate the national need of the time. Biophysicists who had worked on biological sounding rockets were drawn to the military sector and continued to contribute to human spaceflight in post-Mao China. Besides the rocket-and-space missions which provided the material context for biophysics to expand in the late 1950s and early 1960s, Chinese biophysicists also created research and educational programs surrounding biophysics by exploiting the institutional opportunities afforded by the policy emphasis on science's role to drive modernization. Biophysics' tie to nationalistic and utilitarian goals highlights the merits of approaching modern Chinese history from disciplinary, material, and institutional perspectives.

ABSTRACT
The early desire for and the pursuit of literacy are often mentioned in the teeming volumes devoted to African-American history. However, stories, facts, and figures about the acquisition of numeracy by African Americans have not been equally documented.
The focus of this study was to search for the third R, this is the numeracy and mathematics experiences of African Americans who were born in, and before, 1933. The investigation of this generational cadre was pursued in order to develop oral histories and narratives going back to the early 1900s. This study examined formal and informal education and other relevant mathematics-related, lived experiences of unacknowledged and unheralded African Americans, as opposed to the American anomalies of African descent who are most often acknowledged, such as the Benjamin Bannekers, the George Washington Carvers, and other notables.
Quantitative and qualitative data were collected through the use of a survey and interviews. Quantitative results and qualitative findings were blended to present a nuanced perspective of African Americans learning mathematics during a period of Jim Crow, segregation, and discrimination. Their hopes, their fears, their challenges, their aspirations, their successes, and their failures are all tangential to their overall goal of seeking education, including mathematics education, in the early twentieth century. Both formal and informal experiences revealed a picture of life during those times to further enhance the literature regarding the mathematics experiences of African Americans.
Key words: Black students, historical, senior citizens, mathematics education, oral history, narrative, narrative inquiry, socio-cultural theory, Jim Crow

Description
Most studies on refugee populations tend to focus on mental health issues and communicable diseases. Yet, reproductive health remains a major aspect of refugee women's health needs. African refugee women in the United States continue to experience some difficulties in accessing reproductive health services despite having health insurance coverage. The purpose of this study was to understand the reproductive health journey of African refugee women resettled in Phoenix, Arizona. This study also explored how African refugee women's pre-migration and post-migration experiences affect their relationships with health care providers. The study was qualitative consisting of field observations at the Refugee Women's Health Clinic (RWHC) in Phoenix, verbally administered demographic questionnaires, and semi-structured one-on-one interviews with twenty African refugee women (between the ages of 18 and 55) and ten health care providers. The findings were divided into three major categories: pre-migration and post migration experiences, reproductive health experiences, and perspectives of health care providers. The themes that emerged from these categories include social isolation, living between two cultures, racial and religious discrimination, language/interpretation issues and lack of continuity of care. Postcolonial feminism, intersectionality, and human rights provided the theoretical frameworks that helped me to analyze the data that emerged from the interviews, questionnaire and fieldnotes. The findings revealed some contrasts from the refugee women's accounts and the accounts of health care providers. While refugee women spoke from their own specific social location leading to more nuanced perspectives, health care providers were more uniform in their responses leading to a rethink of the concept of cultural competency. As I argue in the dissertation and contrary to conventional wisdom, culture per se does not necessarily translate to resistance to the American health care system for many African refugee women. Rather, their utilization (or lack thereof) of health services are better conceived within a broader and complex context that recognizes intersectional factors such as gender, racialization, language, displacement, and class which have a huge impact on the reproductive health seeking patterns of refugee women.

Description
HIV/AIDS is the sixth leading cause of death worldwide and the leading cause of death among women of reproductive age living in low-income countries. Clinicians in industrialized nations monitor the efficacy of antiretroviral drugs and HIV disease progression with the HIV-1 viral load assay, which measures the copy number of HIV-1 RNA in blood. However, viral load assays are not widely available in sub-Saharan Africa and cost between 50-$139 USD per test on average where available. To address this problem, a mixed-methods approach was undertaken to design a novel and inexpensive viral load diagnostic for HIV-1 and to evaluate barriers to its adoption in a developing country. The assay was produced based on loop-mediated isothermal amplification (LAMP). Blood samples from twenty-one individuals were spiked with varying concentrations of HIV-1 RNA to evaluate the sensitivity and specificity of LAMP. Under isothermal conditions, LAMP was performed with an initial reverse-transcription step (RT-LAMP) and primers designed for HIV-1 subtype C. Each reaction generated up to a few billion copies of target DNA within an hour. Presence of target was detected through naked-eye observation of a fluorescent indicator and verified by DNA gel electrophoresis and real-time fluorescence. The assay successfully detected the presence of HIV in samples with a broad range of HIV RNA concentration, from over 120,000 copies/reaction to 120 copies/reaction. In order to better understand barriers to adoption of LAMP in developing countries, a feasibility study was undertaken in Tanzania, a low-income country facing significant problems in healthcare. Medical professionals in Northern Tanzania were surveyed for feedback regarding perspectives of current HIV assays, patient treatment strategies, availability of treatment, treatment priorities, HIV transmission, and barriers to adoption of the HIV-1 LAMP assay. The majority of medical providers surveyed indicated that the proposed LAMP assay is too expensive for their patient populations. Significant gender differences were observed in response to some survey questions. Female medical providers were more likely to cite stigma as a source problem of the HIV epidemic than male medical providers while males were more likely to cite lack of education as a source problem than female medical providers.

Description
WHO estimates that 830 women die every day due to maternal health complications. The disparities in maternal health are unevenly distributed between wealthy and poor nations. Ethiopia has one of the highest mortality rates in the world. Existing high maternal mortality rates worldwide and in Ethiopia indicate the shortcomings of maternal health interventions currently underway. Understanding the socio-cultural, economic and political factors that influence maternal health outcomes locally while simultaneously examining how global reproductive and development programs and policies shape and influence the reproductive needs and knowledge of women is important. Employing feminist and African indigenous methodologies, in this research I explore maternal health issues in Ethiopia in two of the largest regions of the nation, namely Oromia and Amhara, more specifically in Seden Sodo and Mecha districts. Using qualitative interviews and focus group discussions, I examined the various socio-cultural, political and economic factors that influence maternal health outcomes, assessing how gender, class, education, marriage and other social factors shape women's health outcomes of pregnancy and childbirth. I also explored how global and local development and reproductive health policies impact women's maternal health needs and how these needs are addressed in current implementation strategies of the Ethiopian health system. Recognizing women's social and collective existence in indigenous African communities and the new reproductive health paradigm post-ICPD, I addressed the role of men in maternal health experience. I argue that global and local development and reproductive policies and their implementation are complex. While comprehensive descriptions of national and maternal health policies on paper and gender-sensitive implementation strategies point toward the beginning of a favorable future in maternal health service provision, the global economic policies, population control ideas, modernization/development narratives that the nation employs that focus on biomedical solutions without due emphasis to socio-cultural aspects have a detrimental effect on maternal health services provision. I advocate for the need to understand and include social determinants in policies and implementation in addition to legal enforcement and biomedical solutions. I also argue for alternative perspectives on masculinities and the role of men in maternal health to improve maternal health service provision.
