Drawing upon self-determination theory (SDT) based models of motivational resilience, the following dissertation contains three studies that expand upon the current literature by investigating how processes of motivational resilience, or children's general capacity to handle the everyday academic stressors they encounter at school, are connected to the complex social ecologies created by the intersecting contexts of school and home. Study 1 examined whether family motivational support predicted increases in student reengagement through its effect on subsequent levels of students' self-system processes of relatedness, competence, and autonomy in a sample of 590 early adolescents from an urban middle school in the …

Research Review: "A Novel Mind-Body Podcast Program For Military And Veteran Caregivers", Institute For Veterans And Military Families At Syracuse University

Institute for Veterans and Military Families

This research review discusses how mind-body interventions can alleviate stress and enhance health for caregivers, but they are not widely accessible in many communities. To overcome this limitation, a study converted an 8-week mind-body program into a 28-day daily podcast series featuring education on stress response, relaxation techniques, and self-compassion exercises. The program was tested with 55 military caregivers, all cisgender women averaging 42.3 years old, and evaluations at the start, halfway through, and at the end of the program revealed notable reductions in stress, depression, and physical issues, along with improved social role performance, indicating that a daily mind-body …

America Is Unprepared To Meet The Needs Of Its Growing Older Adult Population, Sierra Kaplan

Population Health Research Brief Series

In 2030, nearly 73 million Americans will be aged 65 years or older. As Americans continue to have fewer children than in the past, the number of older adults will outnumber children. Thus, fewer young adults will be around to support and care for the older adult population. Coupled with COVID-19 pandemic-driven disruptions to the healthcare industry, America’s health and aging care system is unprepared to support its large and growing older adult population. Over time, we will see increased health care scarcity and inequality in the distribution of elder care services, especially with continued healthcare worker shortages and drastic …

The Planning Strategy For Electric Vehicle Charging Stations In The Road Transportation Network Synchronized With The Distribution Network, Muthukannan S

Theses and Dissertations

Electric vehicles (EVs) are recognized as a potentially effective solution to the environmental crisis and fuel deficit that modern metropolises are currently experiencing. Meanwhile, the expansion of EVs and their haphazard charging would negatively affect the road transportation network (RTN) as well as the electric distribution network (EDN). The proper infrastructure for the electric vehicle charging station (EVCS) will enhance the effective utilization of energy of both the networks.

This research work proposes a two-phase planning strategy for deploying Electric Vehicle Charging Stations (EVCS), considering both static and dynamic factors. The strategy uses a hybrid PSO-DS algorithm which is a …

Why We Need A Long View Of Abolition To End The School-To-Prison Pipeline, Karen Sotiropoulos

History Faculty Publications

Drawing on experiential, literary and historical narratives, this article connects the long history shaping the school-to-prison-pipeline to the contemporary experiences of Black youth in today’s educational system. It maps abolitionism from its origins as a movement to end slavery through the ongoing Black freedom struggles that have challenged state and vigilante violence throughout the eras of Jim Crow and Civil Rights to today’s efforts to dismantle the prison state. By situating the criminalization of African American education from our nation’s founding until the present with particular focus on the post Brown years, the article stresses how policies that funded policing …

Assessing The Relative Sustainability Of Point-Of-Use Water Disinfection Technologies For Off-Grid Communities, Bright C. Elijah, Ali Ahmad, Yalin Li, Jaime Plazas-Tuttle, Lewis Stetson Rowles

Civil Engineering & Construction: Faculty Publications

Point-of-use (POU) water disinfection technologies can be adopted to provide access to safe drinking water by treating water at the household level; however, navigating various POU disinfection technologies can be difficult. While numerous conventional POU devices exist, emerging technologies using novel materials or advanced processes have been under development and claim to be of lower cost with higher treatment capacity. However, it is unclear if these claims are substantiated and how novel technologies compare to conventional ones in terms of cost and environmental impacts when providing the same service (i.e., achieving a necessary level of disinfection for safe drinking water). …

Angler Knowledge Of Live Bait Regulations And Invasive Species: Insights For Invasive Species Prevention, Alexis L. Gerber, Hannah Mulligan, Mark A. Kaemingk, Alison A. Coulter

Biology Faculty Publications

The prevention of aquatic invasive species is one of the most cost-effective management strategies for reducing negative ecological, economic, and social impacts to freshwater ecosystems. The release of leftover baitfish via the live bait trade has been identified as a high-risk pathway for introducing invasive species beyond physical barriers (e.g., mountains, dams). To assess differences in behavior surrounding live bait use and angler knowledge of invasive species, we conducted in-person angler surveys at waterbody access sites (i.e. boat ramps with available shore fishing and a shore fishing location with no boat ramp) along the Missouri River, above and below Gavins …

Atrocity Prevention In The Digital Era: Adapting Norms, Laws, And Code To Changes In The Ways Atrocities Are Committed, David J. Simon, Samhitha Josyula, Joshua Lam, Julian D. Melendi

Genocide Studies and Prevention: An International Journal

Emerging digital technologies have changed some of the ways that genocides are planned and executed. This paper examines those differences, calling attention to how changes in the execution of genocide should prompt a shift in the approaches to atrocity prevention. It develops a conceptual framework addressing how atrocity prevention efforts might adapt to new technology within three realms of potential prevention efforts: the ethical (norms), the legal (laws), and the digital (code).

Security Or Vulnerability? The Optics Of Data In The Humanitarian Sphere, Nicole M. Bennett, Hamid Ekbia

Genocide Studies and Prevention: An International Journal

Governments, humanitarian agencies, and non-government organizations increasingly resort to data-driven techniques to meet the challenges they face in dealing with growing mobile populations such as refugees. Such techniques originate in bureaucratic administrations of the 19th century and, even earlier, in slave trade and plantation accounting methods. They were then perfected in logistics and global supply chain management of the twentieth and twenty-first centuries, especially with the advent of information technology. We examine the application of these techniques in humanitarian cases, seeking to contextualize them within the framework of logistic security. To understand the drivers of this trend, we introduce the …

Characterizing And Manipulating Intra-Die Performance Variation Of Fpgas And Its Application In Security, Hayden C. Cook

Theses and Dissertations

Field Programmable Gate Arrays (FPGAs) are reconfigurable, high-performing devices that are often used in critical applications. However, like all semiconductors, FPGAs experience transistor aging that can lower performance and lead to device failures. Additionally, device aging also has several security implications. Therefore, understanding the aging mechanisms behind transistor aging is necessary to ensure the reliability of FPGAs. However, current aging studies either rely on simulation alone or are unable to isolate aging effects on specific elements within the FPGA. This dissertation uses the reconfigurability of FPGAs to develop novel aging techniques that allow for the targeted aging of specific areas …

Chief Sustainability Officer’S Role Centrality And Corporate Sustainability Performance, Taiwo Abraham, Gabriel Owusu, Xuan Wang

Management Faculty Publications

Corporate Sustainability Performance (CSP) has gained substantial attention as firms recognize its potential impact on competitive advantage. In response, there has been a significant increase in the appointment of Chief Sustainability Officers (CSOs) tasked with managing sustainability performance and integrating systemic sustainability initiatives for business growth. In this research, we draw upon upper echelon theory and social network theory to argue that merely having a CSO does not enhance CSP. However, the centrality of CSO within organizational networks significantly augments CSP. Further, leveraging literature from institutional theory and stakeholder theory, we provide a fresh perspective on how organizations should approach …

Revealing Structural Evolution Of Nickel Phosphide-Iron Oxide Core–Shell Nanocatalysts In Alkaline Medium For The Oxygen Evolution Reaction, Ryan H. Manso, Jiyun Hong, Wei Wang, Prashant Acharya, Adam S. Hoffman, Xiao Tong, Feng Wang, Lauren F. Greenlee, Yimei Zhu, Simon R. Bare, Jingyi Chen

Chemistry & Biochemistry Faculty Publications and Presentations

Metal phosphide-containing materials have emerged as a potential candidate of nonprecious metal-based catalysts for alkaline oxygen evolution reaction (OER). While it is known that metal phosphide undergoes structural evolution, considerable debate persists regarding the effects of dynamics on the surface activation and morphological stability of the catalysts. In this study, we synthesize NiP_x-FeO_x core–shell nanocatalysts with an amorphous NiP_x core designed for enhanced OER activity. Using ex situ X-ray absorption spectroscopy, we elucidate the local structural changes as a function of the cyclic voltammetry cycles. Our studies suggest that the presence of corner-sharing octahedra in the …

Teacher Retention And School Characteristics In Tennessee: A Human Relations Theory Correlation Study, Crystal Sarina Watts

Electronic Theses and Dissertations Archive

Teacher retention is a foundational issue and schools have historically struggled to retain teachers. Previous research indicates that teachers leave the profession at high rates before year five of teaching expertise. Lack of teacher retention contributes to instability and lack of trust in school districts. This secondary data study explores whether teacher retention predicts institutional outcomes based on teacher perceptions of school climate, school leadership, student achievement, and student behavior in Tennessee public school districts. This research answers whether student achievement, school climate, school leadership, percentages of disadvantaged, special education, minority, suspended, and chronically absent students predict teacher retention in …

Laser-Powder Bed Fusion Of Ti-6al-2sn-4zr-2mo-0.08si (Ti-6242) Alloy: Process-Microstructure-Properties Relationship, Harish Chandra Kaushik

Electronic Theses and Dissertations Archive

The current work is focused on Laser-powder bed fusion (L-PBF) of Ti-6Al-2Sn-4Zr-2Mo-0.08Si (Ti-6242) which is a near-α titanium alloy used for high-temperature applications. The fabrication of Ti-6242 is common using conventional techniques such as casting, forging, and powder metallurgy whereas the L-PBF of Ti-6242 is comparatively new. This offers the opportunity to develop the process-microstructure-property relationship of Ti-6242 fabricated through L-PBF. This includes tasks like 3D printing of Ti-6242 followed by the study of mechanical properties and the governing microstructures of as-built (AB) and after post-processing (heat treatment in this case). In the current study, the 3D printing of Ti-6242 …

Experiences Of Food Insecurity Among Single Mothers Pursuing Secondary Education, Amber Bernard

Walden Dissertations and Doctoral Studies

The number of single mothers continues to grow across the nation, and many are at a socioeconomic disadvantage. Little research focuses, however, on how single mothers describe their experiences of balancing motherhood, work, and pursuing higher education, all while undergoing food insecurity. Lazarus and Folkman’s transactional theory of stress and coping was used to formulate the research design. Semistructured interview questions were used to answer the question of how single mothers with food insecurity describe their experiences pursuing higher education. A generic qualitative research approach was utilized in this study. Interviews were conducted with 10 single mothers pursuing postsecondary education …

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The timely detection of underground natural gas (NG) leaks in pipeline transmission systems presents a promising opportunity for reducing the potential greenhouse gas (GHG) emission. However, existing techniques face notable limitations for prompt detection. This study explores the utility of Vegetation Indicators (VIs) to reflect vegetation health deterioration, thereby representing leak-induced stress. Despite the acknowledged potential of VIs, their sensitivity and separability remain understudied. In this study, we employed ground vegetation as biosensors for detecting methane emissions from underground pipelines. Hyperspectral imaging from vegetation was collected weekly at both plant and leaf scales over two months to facilitate stress detection …
