The Moderating Effects Of Community Involvement On The Association Between Witnessed Community Violence And Mental Health Outcomes Among Black Adolescents, Curtisha Tamara Shacklewood

Theses and Dissertations

Black youth and adolescents are at a disproportionately high risk for experiencing community violence exposure (CVE) and the potential influence it may have on psychological functioning. Research posits that Black youth who experience community violence are at a significantly higher risk of experiencing elevated internalizing symptoms (e.g., depression) and externalizing symptoms (e.g., delinquency). Previous research has utilized the ecological model to investigate interpersonal protective factors that potentially buffer the effects of CVE, including parental support and family characteristics. However, there is little research that explores community-level factors, such as community activities (e.g., youth activities and parental perception of collective efficacy) …

Leveraging After School Programs As Resources To Support Adolescent Health And Wellbeing Within Underserved Communities: A Qualitative Study, Olivia Staples

Theses and Dissertations

Over the past decade, youth have shown a consistent rise in stress, major depression, anxiety, and suicide, with underserved youth (low-income, minoritized communities) at greatest risk of exposure to chronic stress, related outcomes, and less access to health services (APA, 2017). Afterschool programs (ASPs), which serve as important resources in underserved communities, can be a critical support for youth health and well-being (Afterschool Alliance, 2019). However, few studies have examined ways in which ASPs address the challenges underserved youth face across their ecosystem to promote youth resilience (Jones & Deutsch, 2011). Using qualitative interview data from staff and youth across …

Stem Integration In The Classroom: An Exploratory Case-Study On Teachers Defining Their Stem Identity And Role As A Stem Educator, Tawana Guillaume

Theses and Dissertations

The push for inclusion of science, technology, engineering, and mathematics (STEM) as a meta-discipline in K-12 education is recognition that the challenges faced by society require technology skills, interdisciplinary problem-solving, and an increased number of people entering STEM professions (Dare et al., 2014; English, 2016; Fan et al., 2021; Holstein & Keene, 2013; Roehrig et al., 2012, 2021; Sanders, 2008). The dissertation in practice explored STEM teacher identity and conceptions of STEM as a function of STEM professional experience outside of the field of education. The exploratory casestudy sought to identify the relationship between STEM career-based experiences – specifically the …

Improved Extraction And Detection Of Disinfection Byproducts, Impacts Of Wildland-Urban Interface Wildfires On Drinking Water, And Change In Disinfection Byproducts Over Time In Chlorinated Vs. Chloraminated Distribution Systems, Patrick Thomas Justen

Theses and Dissertations

Drinking water disinfection is critical to prevent the occurrence of waterborne pathogens in drinking water. However, disinfection causes the unintended formation of disinfection byproducts (DBPs) through the reaction of disinfectants (e.g., chlorine, chloramine) with natural organic matter (NOM), algal matter, or anthropogenic pollutants present in source waters. Exposure to DBPs is associated with increased bladder cancer, colorectal cancer, miscarriage, and birth defects. The U.S. EPA currently regulates eleven DBPs in drinking water—four trihalomethanes, five haloacetic acids, bromate, and chlorite. However, research shows that DBP related toxicity in drinking water is driven mainly by other, non-regulated DBPs, particularly iodinated DBPs and …

Thesis: Comparing Functional And Effective Brain Connectivity Metrics For Eeg, Diksha Srishyla

Theses and Dissertations

Background:Brain connectivity measures have been used to study communication between brain regions using electroencephalography (EEG). Functional and effective connectivity estimate the synchronization and the flow of information between regions, respectively. However, findings from studies using different measures to investigate similar connections do not converge. To guide the selection of functional and effective connectivity measures in future studies, we systematically compared a set of measures in the context of resting state EEG. We examined four functional connectivity metrics (coherence (Coh), the imaginary part of coherence (imCoh), the corrected imaginary part of phase lagged value (ciPLV), the debiased weighted phase-locking index (dwPLI)) …

Ai-Driven Autonomous Manufacturing: A Novel Taxonomy, Vision-Guided Planning, And Diversity-Aware Active Learning Frameworks, Ibrahim Yousif

Theses and Dissertations

Manufacturers face two opposing challenges: the escalating demand for customized products and the pressure to reduce lead times. Current manufacturing equipment, although reliable, operates at the limits of its technology and lacks adaptability to dynamic environments. This trade-off has been described as the optimal degree of automation, a threshold beyond which further automation incurs more cost than benefit. Smart manufacturing has introduced adaptive, data-driven systems, but many deployments still lack the contextual adaptability and autonomous decision-making required to handle unplanned disruptions. This underscores the need for intelligent, autonomous systems capable of real-time adaptation without costly reconfiguration, minimizing human intervention during …

Multi-Perspective Feature Learning For Facial Expression Recognition In The Wild, Xiangyu Hu

Theses and Dissertations

With the rapid progress of deep learning, Facial Expression Recognition (FER) has seen substantial improvements in performance, particularly “in the wild” meaning real world conditions. Despite these advances, most existing methods extract features from facial images as the sole emotional cues, which limits the model’s ability to capture the full complexity of human emotional expressions.

In reality, facial expressions are composed of diverse and multi-perspective information, including appearance-based cues and geometric structural deformations due to activations of facial muscles. Depending exclusively on one type of representation may fail to exploit the complementary nature of these cues, an issue that becomes …

From Seapower To Shining Seapower, Michael Lee

Publications and Research

The liberal world order is dead: the United States has abandoned both the domestic and international institutional commitments that enabled it to function. How can liberal democracy survive in an increasingly hostile world? How can liberal democracies grow powerful enough to defend themselves without becoming the empires they fear? I argue that seapowers have historically represented a distinct kind of hegemon, that is more amenable to international cooperation, and democracy at home. Moreover, the transition from declining seapowers to rising ones has played a vital role in preserving a space for more liberal states (relative to their historical context), such …

The Role Of Employee Engagement In Predicting Risk Management Outcome, Jenny Tan

Dissertations and Theses Collection (Open Access)

Risk performance is a key business performance indicator as it measures how well an organization manages its uncertainties. Well-balanced risk performance instills confidence in stakeholders (including investors) and improves organizational performance broadly speaking. This dissertation studies the relationship between Perceived Organizational Support, employee engagement and risk appetite and how that relates downstream to organisational risk performance. Using the lens of Social Exchange Theory (SET; Blau, 1964) I examine how perceived organizational support (POS) predicts employee engagement and how this then relates to risk appetite and subsequent levels of risk taking in an organization. I then make predictions about how exchange …
