Advancing Healthcare Through Technology
(2024-11-19) Wane, Khadija; Park, Jiun; Choi, Eugene; Roy, Rishit; Ahmed, Aryaan; Huffman, Benjamin
Adopting eHealth technologies has great potential to increase access to better quality healthcare services within Singapore. By increasing the efficiency, accessibility, and presence of these crucial services, digital healthcare has great potential to advance national well-being, good health, and promote equity. Since the 2010s, Singapore has taken on national initiatives to spread the adoption of eHealth technologies and modernize its healthcare sector. However, throughout the past decade, certain ethical implications have risen. Contrastingly, while digital healthcare has the potential to reduce inequalities, it may also widen them if implemented without regard to the nation’s pre-existing demographic inequalities. This study builds on previous research, which has established the potential and drawbacks of eHealth, now analyzing the effects of its implementation on health inequalities in Singapore. Furthermore, this study controls for specific demographic variables —age, income, and citizenship status— to evaluate if the effects of eHealth on the quality and accessibility of health services in Singapore differs based on such traits. Using a mixed-methods approach, a comprehensive analysis of Singapore's digital healthcare was conducted. Primarily, qualitative data was obtained through interviews with government and eHealth officials along with first-hand accounts from Singaporean citizens. To supplement, quantitative data on health statistics were collected and evaluated in the Global Development and Design Healthcare Quality Index (GDD HQI)— a formula created by the Global Development and Design lab to measure the effects of income. age , and citizenship status on the magnitude of healthcare inequality present in Singapore during a given year. Results from the mixed-methods approach signify that Singapore’s implementation of eHealth technologies has increased national well-being and reduced inequalities. Furthermore, results show when Singapore’s digitization efforts focus on the elderly, lower-income, and non-citizen populations, the potential of increasing health inequalities for the most marginalized significantly decreases. Thus, this research sheds light on the necessity for Singapore’s future digitization efforts to lead with a focus on marginalized communities to guarantee good health and well-being for all of Singapore. Ultimately, this research can help guide the development of healthcare agendas within developing countries with similar political structures and culture.

Short-lived subduction interface fluid transport at the depths of episodic tremor and slow slip [dataset]
(2025) Hoover, William; Penniston-Dorland, Sarah; Teng, Fang-Zhen; Penniston-Dorland, Sarah
Geophysical observations and geologic evidence suggest the source region of deep episodic tremor and slow slip (ETS) at the subduction interface is fluid rich and subject to high pore fluid pressure, however the mechanistic role of fluid in producing this seismic phenomenon remains debated. Previous studies have linked fluid movement and seismicity through diffusion chronometry, capable of resolving fluid transport durations at timescales comparable to the seismic cycle, but none have directly constrained the timescales of fluid transport at the subduction interface, the inferred source region of ETS. We invert measured Li concentration and isotope profiles using a Monte Carlo Li advection-diffusion model to constrain the duration (and associated uncertainties) of fluid transport around two partially-reacted metamafic blocks from an exhumed subduction interface (Amphibolite Unit, Catalina Schist, California). Both blocks yield time-integrated durations of fluid transport of ~40 years (years to centuries at 95% confidence) much shorter than the lifetime of these rocks in the subduction zone and comparable to, or longer than, the longest slow slip events. This suggests that fluid transport does not occur continuously at the subduction interface but rather reflects transport through fracture permeability consistent with fault-valve type models of fluid transport and related pore pressure fluctuation and frictional instability. The presence of peak metamorphic quartz + garnet veins in the rinds supports the formation and healing of fracture permeability as the process controlling fluid transport at the subduction interface. The fluid transport recorded by these blocks may be the geologic record of geophysically-observed variations in Vp/Vs during the slow slip cycle in modern subduction zones.

“WOMEN IN THE STRUGGLE”: WOMEN OF COLOR COALITIONAL RELATIONALITIES IN THE COLD WAR ERA
(2025) Knowles, Lenora Renee; Rowley, Michelle V; Women's Studies; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
This dissertation revisits the 1970s as a key period of unprecedented radical left organizing to explore the complex modes of solidarity integral to the political thought and activism of Black women and Latinas engaged in radical left grassroots movements during the Cold War. In doing so, this project complicates existing investigations of that period and notions of solidarity by exploring the fundamental role that coalition played in the work of the Third World Women’s Alliance (TWWA), a Marxist-Leninist, anti-imperialist Third World women’s organization. Utilizing the primary methods of qualitative expert interviews and archival research, I conduct a relational, interdisciplinary, and intersectional study of the coalitional organizing of the Black women and Latinas who spearheaded the Third World Women’s Committee to Celebrate International Women’s Day (1974-1980) stewarded by the Bay Area, California chapter of the TWWA and El Comité Lolita Lebrón (1974-1977), a committee of the New York City chapter of the TWWA. Through this analysis, I theorize coalitional relationalities as a broad framework for understanding the interconnected political, economic, affective, aesthetic, and ontological relationships that these organizers forged over racial/ethnic lines, time, and multiple scales, to resist colonial categories of difference and hierarchies of power toward freedom. Original interviews with Dr. Vicki Alexander, Frances Beal, Linda Burnham, Rebecca Carrillo, Dr. Concha Delgado-Gaitán, Cheryl Perry League, Dr. Patricia Romney, Dr. Melanie Tervalon, and Dr. Ana Celia Zentella, bring to the fore the everyday coalitional organizing practices and theories of Black women and Latinas who were active as rank-and-file members and leaders in both chapters of the Third World Women’s Alliance. Through archival research I layer into my analysis, close readings of Triple Jeopardy: Racism, Imperialism, Sexism, organizational records, internal position papers, and notes, along with other English and Spanish language movement ephemera of the TWWA and adjacent groups. Furthermore, I examine state responses to their organizing employing close readings of redacted FBI files, interviews, and organizational documents. I analyze the state’s racializing surveillance (Browne 2015), and repression of these activists as connected to capital’s routinized exploitation and surveillance of US Third World women workers. Additionally, I map the resistance strategies that these activists employed to survive and challenge such violence. State surveillance of the TWWA demonstrated the decolonial potentialities of coalitional organizing among poor and working-class women of color as the state engaged in a violent Cold War project of capitalist nation-building.

Insight Gained from Maryland’s WBL and Career Counseling Certificate Program
(2025-09-08) Love, Tyler S.; Canterbury, A.; Fales, A.; Smith, C. W.
With legislation requiring individualized career counseling for every secondary student in Maryland, it was apparent there was a need for educating and upskilling professionals to meet the career coaching goals set forth in Maryland's Blueprint legislation. An amalgam of strategies for preparing career coaches in Maryland have been implemented since the release of the Blueprint. This presentation explores Maryland’s first higher education system-approved program focused on preparing career coaches in alignment with the Blueprint and the Code of Maryland Regulations (COMAR). This program, developed by the University of Maryland Eastern Shore (UMES), has provided some valuable insight as a result of working with cohorts of career coaches from across the state. Faculty from this program with expertise in career coaching and work-based learning coordination in Maryland’s public schools shared their insights from working with the career coach cohorts. Attendees participated in the career counseling case conceptualization activity attached to at the end of the slides. Some helpful resources compiled during the first year of this program were also shared with participants in the Resources Handout included with the slides. Additionally, analyses of career coaches’ quantitative and qualitative survey feedback were presented, and participants learned how those findings were being used to continuously improve the career coaching preparation experience.

COMPARISON OF EFFECTS OF PROCESS TECHNOLOGY-DERIVED INPUT PARAMETERS OF DIE-LEVEL FAILURE MODELS
(2025) Vora, Rudra Bipinbhai; Das, Diganta; Mechanical Engineering; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
In integrated circuits, time-dependent dielectric breakdown, hot carrier injection, andelectromigration are primary die-level wear-out failure mechanisms. Failure models for these mechanisms can be used to assess and compare the parts based on their ability to withstand these failure mechanisms. The failure models require electrical input parameters: gate voltage, drain current, and current through interconnect, as well as dimensional input parameters: gate oxide thickness, gate length, and die metallization dimensions. These input parameters are unavailable in traditional documentation, such as datasheets and application notes. As a result, part users face difficulty using the failure model for part assessment. This thesis presents methodologies to obtain die-level electrical and dimensional input parameters for individual parts. The approach developed to find the input parameters uses the process technology information of a part and literature on process technology. The electrical input parameters for the time-dependent dielectric breakdown and hot carrier injection failure model are determined from transistor-level voltage-current characteristic curves provided in the literature on process technologies. The methodologies to determine the electrical input parameters are developed by utilizing transistor circuit information and the associated characteristic curves. Part manufacturers use different technologies and design rules, leading to differences in inputparameters such as die-level dimensions and electrical and environmental loads. These variations affect the ability of parts to withstand die-level failure mechanisms. Therefore, a die-level comparative assessment should be performed to compare and select the parts. Comparative assessment refers to quantifying and comparing the influence of die-level input parameters on time-to-failure of parts for individual die-level failure mechanisms using simulation-based design of experiments. Identifying the parameters that affect the part’s time-to-failure using a simulation-based design of experiments supports decision-making for derating considerations, acceptable manufacturing variations, and part selection. This thesis provides guidelines for extracting input parameters for die-level failure mechanisms and a methodology to perform comparative part assessment based on the application load condition of the system.
