From Cuffs To Compassion: The Impact Of Relational Policing De-Escalation Approaches On Public Perceptions Of Safety, Satisfaction, Procedural Justice, And Police Legitimacy., Brook Snider

Theses and Dissertations (Comprehensive)

Academics, policy makers, and the public have called for the prioritization of de- escalation training and use in public-police interactions to reduce police use of force (PUoF) (e.g., Dubé, 2016; Iacobucci, 2014; Todak, 2017; Wortley et al., 2021). In response to various calls to action, the Ministry of the Solicitor General launched the Ontario Public-Police Interactions Training Aid Framework in 2023, which emphasizes the importance of utilizing a relational policing approach in public-police interactions (see Lavoie et al., 2022). However, despite changes in police training frameworks, relatively little is known about PUoF in Canada (Wortley et al., 2021), with similarly …

Pediatric Cancer Incidence, Temporal Trends, And Mortality In The United States By Health Disparities Indicators, Seer (1973-2014), Prachi P. Chavan, Laurens Holmes Jr.

Epidemiology, Biostatistics, & Environmental Health Faculty Publications

Background: Pediatric cancer incidence has been increasing in the United States, despite improvement in pediatric cancer survival. This steady increase in incidence trends is not completely understood but maybe associated with social and environmental factors. In this study we aimed to assess the cumulative incidence, temporal trends, and mortality rates in pediatric cancer. Additionally, we examined sub-group variability in both incidence and mortality rates. Methods: Data from Surveillance, Epidemiology, and End Results (SEER) −18 from 1973–2014 were used for the purpose of analysis in this study. Age-adjusted incidence rates were used to assess temporal trends in cancer among children aged < 1–19 years. Univariable and multivariable binomial regression models were used to examine the association between race and cancer mortality while adjusting for potential confounders. Results: There were 92,594 cancer diagnoses during this period. White children comprised 74,758, (80.7%), black children 10,030, (10.8%), and other races 6648, (7.2%). Overall the age-adjusted cumulative incidence was slightly higher among white children (16.4%) than black children (12.4%) and other (13.0%). Children aged 15–19 years and those in metropolitan regions were more likely to be diagnosed with pediatric cancer. Relative to females, males were 16% more likely to die from the disease [adjusted Risk Ratio (aRR): 1.16, 95% Confidence Interval (CI): 1.09–1.22]. Additionally, compared to white children, black children had higher mortality rates [(aRR): 1.37, 99% CI: 1.23–1.52]. Conclusions: There is an increasing trend in pediatric cancer incidence; while white children have the highest incidence, black children and males indicated a survival disadvantage, indicative of racial and sex variability in overall pediatric cancer in the United States.

Disparities In Breast Cancer Detection Modalities And Outcomes Among Geriatric Female Cancer Patients, Zhaoli Liu, Mathilda Nicot-Cartsonis, Biai D E Digbeu, Daoqi Gao, Sharon H Giordano, Yong-Fang Kuo

Faculty, Staff and Student Publications

This study examined racial and geographic disparities in breast cancer detection modalities (screening-, diagnostic-, or non-mammography) with cancer stage and mortality. A retrospective cohort study was conducted using Texas Cancer Registry-Medicare linkage data for geriatric women. Cancers detected through screening and diagnostic mammography had 43 % (95 % CI, 39 %-46 %, p < .0001) and 31 % (95 % CI, 27 %-35 %, p < .0001) lower all-cause mortality, and 49 % (95 % CI, 41 %-54 %, p < .0001) and 37 % (95 % CI, 32 %-43 %, p < .0001) lower cancer-specific mortality, respectively, compared to non-mammography-detected breast cancers. Patients from rural areas were 17 % (95 % CI, 1.06 - 1.29) more likely to be diagnosed with mid- (p = .0023) and advanced stage (p = .003) cancers compared to their urban counterparts. Racial or geographic disparities in cancer detection modalities with associated mortality no longer exist after adjusting for covariates. Healthcare professionals can leverage these findings to promote rural cancer health equity.

Evaluating Tropospheric Delay Modeling For Enhanced Geospatial Accuracy, Adeyinka Olaoluwa Olaseinde

Masters Theses

Interferometric Synthetic Aperture Radar (InSAR) is a vital technique for monitoring ground surface deformation across large spatial scales. However, variability in atmospheric water vapor, pressure, and temperature introduces tropospheric delays that can significantly affect measurement accuracy. These delays are often corrected using outputs from numerical weather prediction (NWP) models. RAiDER, an open-source Python package, facilitates this by estimating tropospheric delays using models such as the High-Resolution Rapid Refresh (HRRR). Previous studies have shown that weather model–based corrections can substantially reduce atmospheric noise in InSAR data but also highlight persistent residual errors, especially at spatial scales smaller than the model grid …

Seagrasses Are Most Vulnerable To Marine Heatwaves In Tropical Zones: Local-Scale And Broad Climatic Zone Variation In Thermal Tolerances, Nicole Said, Chanelle Webster, Simone Strydom, Natasha Dunham, Matthew P. Adams, Kathryn Mcmahon

Research outputs 2022 to 2026

Under a changing climate, it is imperative that we understand how species may respond to temperature impacts, which can differ among populations of the same species due to local drivers. Thermal tolerance data, which can be used to assess an organism's upper thermal limits, is valuable to identify species and/or populations' susceptibility to thermal stress. This study assessed the variation in thermal tolerance of six seagrass species at both broad latitudinal (c. 500–1000 km) and local scales (c. 25 km). Photosynthesis–temperature curves (15–45°C) were conducted, by measuring oxygen in closed incubation chambers, and thermal optima (Topt) was extracted. We found …

The Affective Milieu Of School Market Competition: Using Affect And Governmentality To Study Market Competition, Brad Gobby, Amanda Keddie, Jill Blackmore, Katrina Macdonald

Research outputs 2022 to 2026

This paper integrates insights from affect theory into Foucault’s governmentality framework to analyse school markets. Using a Deleuzian approach to affect, we theorise school markets as an affective milieu that composes the field of competition. Drawing on interviews with staff at two rival high schools, we highlight how an affective milieu that included threat, anxiety, insecurity, resentment and confidence shaped market dynamics. Our analysis shows that affective milieus reflect and reinforce power asymmetries in local school markets and are a condition for generating competitive practices to enhance schools’ capacities to affect and be affected. Our central point is to move …

Constructing Bodies Of Subversion And Resistance: The Carceral Quarantine Of Hiv-Positive Haitian Refugees At Guantanamo Bay Under U.S. Imperialism, Isabelle E. Oringer

Scripps Senior Theses

This thesis investigates the detention of HIV-positive Haitian refugees at Guantánamo Bay in the early 1990s as a case study of medicalized racism and U.S. imperialism. It explores how U.S. public health policy, immigration law, and Cold War-era foreign interventions converged to criminalize and confine Black Haitian bodies, constructing them as threats to national security and public health. By analyzing primary testimonies and media coverage alongside the works of scholars such as Paul Farmer and Naomi Paik, the project reveals how racialized conceptions of disease and subversion informed discriminatory practices that disproportionately targeted Haitian refugees. Furthermore, it examines how the …

Arbitrator Selection Default Rules, Irene M. Ten Cate

American University Law Review

This Article makes the case for changing the default settings for the selection of arbitrators in international commercial arbitration. For three-member tribunals, the rules of most international arbitration institutions provide that each party picks an arbitrator. The institution or the co-arbitrators then select the tribunal’s president. This prescription, which parties may set aside by agreement, codifies longstanding practices and corresponds to the strong preference of international arbitration insiders. Nonetheless, I argue that arbitration rules should default toward institutional selection of all arbitrators.

Switching the default nudges parties that can’t take full advantage of the arbitrator selection game—due to inexperience, lack …
