Preparing Today’S Workforce For Tomorrow’S Autonomous Transportation: Bridging Electrical And Civil Engineering Disciplines, Masoud Ghodrat Abadi, Rohollah Moghadam

Mineta Transportation Institute

Autonomous vehicles (AVs) are expected to transform transportation systems and reshape workforce needs across engineering and related fields. Although existing AV workforce development efforts often emphasize electrical engineering, computer science, and mechanical engineering, transportation engineering remains underrepresented despite its importance to infrastructure, traffic operations, safety, and mobility integration. This study addresses that gap through the development, implementation, and evaluation of an interdisciplinary certificate program, Workforce for Autonomous Vehicle Engineering (WAVE), at California State University, Sacramento. The program was designed to bridge transportation engineering and electrical engineering through a two-step curriculum model consisting of theoretical educational modules and hands-on laboratory activities. …

Online Planning Of Power Flows For Power Systems Against Bushfires Using Spatial Context, Jianyu Xu, Qiuzhuang Sun, Yang Yang, Huadong Mo, Daoyi Dong

Research Collection College of Integrative Studies

A power station or transmission line can be affected due to bushfires, increasing operation costs. We study a fundamental but challenging problem of planning the optimal power flow (OPF) for power systems under bushfires. We develop a model to capture the stochastic nature of bushfire spread based on Moore’s neighborhood model and propose an online optimization modeling framework to sequentially plan power flows in the electricity network. Our framework assumes that bushfire spread is non-stationary over time and that the spread and containment probabilities are unknown. To address these challenges, we develop a contextual online learning algorithm that treats the …

Historicising Nyerere’S Presidency In The Nyakyusa Mythical Narratives, Ignas Fedeo

Zamani: A Journal of African Historical Studies

Julius K Nyerere, the founding President of Tanzania, held office from 1962 to 1985. Much has been written about Nyerere's presidency, with the literature generally falling into two categories: strong advocacy for his decisions, actions, and ideas, and pointed criticism against him. Using narrative and new historicism theories, this article examines the recreation of the history of Nyerere’s presidency in local narratives, specifically Nyakyusa myths. The myths were collected using the oral history interviews from Kyela and Busokelo districts in Tanzania. The Nyakyusa believe that Nyerere was endowed with immense mystical powers, some of which embedded in his stick and …

Governance Success Factors In The Nglanggeran Sustainable Tourism Village, Indonesia, Dwi Kristanti, Hartuti Purnaweni, Ida Hayu Dwimawanti, Teguh Yuwono

The Qualitative Report

Our qualitative case study examines the dynamics of governance in the Nglanggeran Tourism Village, Yogyakarta—a recipient of various national and international awards for sustainable tourism. Through in-depth interviews with 15 stakeholders, field observations, document analysis, and focus group discussions, we identified five key interrelated factors in governance success: (1) community participation and empowerment, (2) transformative leadership, (3) multi-stakeholder collaboration, (4) adaptive strategic planning, and (5) integrated socio-ecological resource management. Our research's significance lies in analysing how these factors interact dynamically in specific socio-cultural contexts to produce adaptive and resilient governance systems. The findings contribute to a theoretical understanding of sustainable …

Three Essays On Social Security Retirement Age Reform And Its Implications For Older Adults, Halim Yoon

Dissertations - ALL

Rising life expectancy and declining fertility rates have led to rapid population aging in many countries. To address the resulting fiscal pressures on social insurance programs and encourage longer labor force participation among older adults, many countries have reformed their public pension systems. In the United States, the Social Security Amendments of 1983 gradually increased the Full Retirement Age (FRA)—the age of eligibility for full, unreduced Social Security benefits—from 65 to 67. While prior research has extensively examined whether this reform delayed Social Security claiming and retirement, much less is known about its broader and longer-term consequences for well-being, including …

U.S. Service Member To Counseling Student, Nicole Marie Arcuri-Sanders, Kellie Forziat-Pytel

Educational Sciences and Organizations

This qualitative descriptive study examines the absence of military career pathways for licensed mental health counselors (MHCs) and the impact of this structural limitation on service members' career transitions. Findings indicate that both combat and non-combat veterans pursued mental health counseling due to personal service-related mental health experiences and dissatisfaction with available care while in service. Despite these challenges, many participants expressed a strong desire to continue serving their country as professional counselors. Over half of the participants reported separating from the military because no occupational role existed for licensed MHCs. At the same time, most indicated they would have …

On Crucial Role Of The Spirit Of Chinese Scientists In Basic Research, Xin Wang, Chuanxi Wang, Changpu Sun

Bulletin of Chinese Academy of Sciences (Chinese Version)

Basic research is the source of original innovation and the foundation for building a strong nation in science and technology. Compared with applied development research and engineering research, basic research is primarily concerned with exploring the frontiers, proposing new concepts, discovering new laws, and establishing new theories. Its outcomes are often difficult to predict in advance and are rarely subject to sufficient experimental and practical verification within a short time frame. These characteristics expose basic research to three inherent challenges in the philosophy of science. First, the experimental verification of fundamental theories often requires a long period of time. Second, …

Reading Between The Lines: An Exploration Of Censorship In United States Public School Libraries, Sally Anne Perz

ETDs from 2020-2029

Between 2021 and 2025, PEN America documented over 22,000 book bans across the United States (US). Yet, with only 451 districts banning out of over 13,000, 97% of US school districts are not engaging in banning. The 451 banning districts represent only 3% of US school districts. While most research examines individual stakeholders, such as librarians and teachers, this study focused on district and community data which do not change as fast as microsystem variables. Since banning occurs at the district level, understanding school district demographics and values may help situate the sociopolitical context of school board decisions to ban …

Identifying Existing Barriers To Equitable Transportation In Birmingham, Alabama, Brandy Rose Mckinney

ETDs from 2020-2029

A transportation system is designed to connect people to essential community resources and support their mobility needs. However, transportation facilities and services in lower-income communities often fail to meet local demands, restricting access to jobs, healthcare, recreation, and other critical services. These gaps disproportionately impact lower-income and vulnerable populations, reducing mobility and overall quality of life. This study aims to (a) define transportation inequity and the measures used to assess it; (b) summarize existing inequities across the United States; (c) examine travel choices, needs, and barriers in lower-income communities in Birmingham, Alabama; and (d) propose strategies to address transportation inequity …

From Hashtags To Regime Change: How Ai-Driven Social Media Algorithms Fueled Youth Protests Against Authoritarianism In Bangladesh But Stalled In Pakistan (2020-2025), Rafia Nishan Abbasi

Electronic Theses and Dissertations

In this research, it has been investigated that how and why youth protests were amplified by AI based social media algorithms in Bangladesh; however, their impacts resulted in occasional and isolated resistance in Pakistan during 2022-25, taking in account the differences in state regulations, platform governance, and civil society networks. While utilizing Mixed-methods approach, this study employs comparative discourse analysis, a structured survey (N=466), semi-structured interviews, legal and policy tracing, and platform data. This research has proposed a novel theoretical framework of Algorithm Regime Mediation (ARM). ARM considers platform algorithms as politically intermingled intermediaries which can determine socio-political outcomes by …

Fentanyl At The Border: A Critical Analysis Of U.S. Customs And Border Protection Strategies Against Synthetic Opioid Smuggling, Patricia Salinas

Doctoral Dissertations and Projects

This dissertation will investigate the efficacy of tactics employed by U.S. Customs and Border Protection (CBP) in detecting and intercepting fentanyl at legal ports of entry along the U.S border during the fiscal years 2022 to 2025. Given that fentanyl continues to be a pivotal element in the ongoing opioid crisis within the United States, it is imperative to understand the mechanisms by which this synthetic opioid is smuggled into the country and to evaluate the efficacy of federal initiatives. These efforts are crucial for protecting public health and enhancing national security. This quantitative study examines fentanyl seizure data from …

Transforming Equity: A Systemic Analysis Of The Equity Model Of Social Justice Education Through The Lens Of Conflict Transformation Theory, Precious J. Golden

University Honors Theses

Current pedagogical theory and practices grounded in social justice aim to rectify systemic barriers to equity, yet despite decades of teaching through a social justice lens, social inequality and cultural division are on the rise.  "Justice," as a noun, has several meanings (Cambridge Dictionary). It can mean "judge", "law," or "fairness," and justice, no matter its meaning or its need, is achieved through methods of conflict resolution and conflict transformation. This inquiry seeks to present conflict transformation as a radical means of achieving transformative social justice, bringing voice to the voiceless and oppressed, and rectifying the contradictions in the current …

Congestion Pricing: A Comprehensive Look At International Congestion Pricing Models And Applying Them To The United States, Ian Ertel

Electronic Theses and Dissertations

Urban traffic congestion imposes large costs through wasted time, excess fuel consumption, air pollution, and lost productivity. Although congestion pricing has been recognized as the economically efficient remedy since Pigou and Vickrey, implementation has been rare. This thesis examines the conditions under which congestion pricing succeeds by analyzing three pioneering cases: London, Singapore, and New York City. Across all three, charges reduced traffic volumes and improved speeds within the priced zones. Benefits extended beyond cordon boundaries, with measurable improvements on untolled suburban roads. The distributional effects depended on how revenues were recycled rather than on the charge itself. Political viability, …

Neoliberalism & The Care Economy: Exploring The Gendered Impacts Of Social Protection Systems, Rachel Carruthers

Electronic Theses and Dissertations

This thesis examines how neoliberal transformation of social protection policy influences gender dynamics within the care economy. Care is necessary for well-being, but traditionally excluded from economic thinking. This thesis completes a historical overview of how care has been incorporated or excluded by different economic paradigms and is anchored in feminist political economy that emphasizes care as a central consideration. A comparative analysis across California, Texas, and Sweden demonstrates how social protection, specifically access to paid parental leave, varies across regimes and results in inconsistent care outcomes. The findings suggest that social protections can reduce some inequalities, but inadequately address …

Induction Programming For Novice Special Education Directors: The Significance Of Informal Supports In The Absence Of Formal Structures, Julie E. Rottier-Lukens

Electronic Theses and Dissertations

The role and responsibilities of a special education director are unique and highly complex when compared to other district-level leadership roles. Since the Individuals with Disabilities Education Act (IDEA) passed in 1975, states gradually increased requirements for certification of these administrative roles, more clearly defining the criteria and standards to incorporate within preparation programs. Despite improvements in preparation programs for special education directors, there continues to be variation in preparation and certification requirements across states and persistent challenges with shortages of special education directors. After completing a preparation program, what support exists for novice special education directors to help them …

Tracing The Flow Of Value In Ecotourism: A Case Study Of Lekki Conservation Center, Lagos, Nigeria, Queen Oluwatobi Olafadehan

Electronic Theses and Dissertations

This study examines the flow of value in ecotourism at Lekki Conservation Center (LCC) in Lagos, Nigeria, using a political ecology framework to analyze how economic benefits, participation opportunities, and environmental impacts are distributed among different community groups. Drawing on semi-structured interviews with 16 community members, participant observation, and photographic documentation, the study investigates how surrounding communities perceive and experience ecotourism, how revenue is understood to be distributed, and in what ways communities are included in or excluded from conservation decision-making. The findings reveal that ecotourism at LCC generates benefits that are unevenly distributed, that community participation in governance remains …

More Than "Programs For Women": Centering Incarcerated Women's Voices In The Evaluation Of Prison Programming, Winter Ohara-Frantz

University Honors Theses

This thesis examines whether correctional programming in women's prisons reflects the self-identified goals and aspirations of incarcerated women. Existing research demonstrates that prison programming can provide meaningful benefits, including skill development, emotional growth, and preparation for reentry. However, much of this scholarship evaluates women based on institutional outcomes rather than asking whether available programs align with women's own educational, vocational, and personal goals. Drawing on survey responses from 23 formerly incarcerated women across the United States, this mixed-methods study explores participants' experiences with vocational, post-secondary, parenting, and other correctional programs. Quantitative findings indicate that while most respondents viewed programming as …

Higher Education Institutions In U.S. Blockchain Innovation Governance Documents, Clarissa Terracciano

Electronic Theses and Dissertations

Blockchain technologies have attracted growing attention as an evolution of digital recordkeeping, prompting interest in higher education governance, credentialing, and data management. Yet, no systematic analysis exists on how U.S. government blockchain documents define institutional roles and governance authority within higher education institutions. As the national blockchain innovation system expands through governance infrastructure, the inclusion of higher education institutions as governing actors is imperative for coherent and equitable deployment. This qualitative study examines what roles the U.S. government blockchain documents assign to higher education institutions within the national blockchain innovation system.

Using innovation systems theory, particularly the triple-helix model of …

Determinants Of Corporal Punishment And Severe Physical Punishment In Egypt: A Mixed-Methods Analysis For Child Protection Policy, Marwa Moustafa Nassef

Theses and Dissertations

Corporal punishment (CP) and severe physical punishment (SPP) remain a major public health, child rights, and child protection policy concern. In Egypt, despite legislative reforms, survey-weighted analysis of the 2021 Egypt Family Health Survey (EFHS) 2021 (CAPMAS, 2022) reveals prevalence rates of 60.5% for CP and 27.4% for SPP among children aged 1–14 (author’s calculations using EFHS-2021, n=7623), yet evidence distinguishing the determinants of routine corporal punishment from escalation to severe physical punishment remains limited in low- and middle-income contexts. Guided by Bronfenbrenner’s ecological framework, this mixed-methods study identifies key drivers of CP and its escalation to SPP among Egyptian …

When School Culture Excludes: Deficit Discourse, Microaggressions, And The Mental Health Of Marginalized Students – A Conceptual Framework With Implications For School Psychology Practice And Equity Policy, Modupe Mercy Oyewunmi

Publications

Deficit-laden language like ‘behavior problem,’ ‘not college material,’ ‘won’t fit in’, ‘not a cultural fit’, operates as a systemic form of implicit bias and microaggression in school settings. Despite decades of research on school belonging and well-being, school psychology has yet to integrate these exclusionary discursive practices into a coherent health-determinant model that also accounts for the current anti-diversity, equity, and inclusion (DEI) policy environment. This conceptual paper proposes a testable framework linking deficit discourse and school-based microaggressions to student identity suppression, academic impostor phenomenon, and educator moral injury, with downstream effects on school mental health outcomes. We situate these …

Does The Availability Of An Additional Set Of Bunker Gear Impact Firefighter Health, Safety, And Operational Readiness?, Ryan Riley

Certified Public Manager® Applied Research

Firefighting is a complex and inherently dangerous profession. Firefighters today face a growing array of occupational hazards, not just from the effects of being exposed to fire and smoke, but also from the personal protective gear they wear, commonly referred to as “bunker” or “turnout” gear. While this gear is designed to protect firefighters in dangerous environments, prolonged use and repeated exposure to smoke, chemicals, and products of combustion can compromise the gear. Research has shown that bunker gear contains and can also retain cancer-causing chemicals. To this end, this paper examines whether the availability of an additional set of …

The Promise And The Punishment: A Critical Analysis Of Pbis At The Intersection Of State Discipline Policies In Louisiana, Ashley D. Willis-Brooks

Doctoral Dissertations

Positive Behavioral Interventions and Supports (PBIS) emerged as a preventative instructional alternative to exclusionary and punitive school discipline practices emphasizing tiered systems of support, data-based decision making, and proactive behavioral instruction. Despite its strong theoretical foundation and widespread adoption, PBIS implementation has produced uneven outcomes, particularly in policy contexts where state discipline statutes continue to authorize exclusionary practices. In Louisiana, PBIS is promoted through state guidance as an evidence-based framework; however, governing discipline policies simultaneously permit suspension, expulsion, and zero-tolerance provisions. This coexistence raises critical questions regarding alignment, coherence, and equity within the state’s discipline system. The purpose of this …

Analyzing Speeding-Related Crash Severity On Louisiana’S Highways, Nelly Akweley Ankrah

Masters Theses

Speeding is a major contributing factor to roadway crashes and remains a significant safety concern. Understanding the factors influencing speeding crash severity and how they vary across roadway environments is essential for developing effective safety countermeasures. A total of 22,151 speeding-related crashes recorded in Louisiana between 2015 and 2024 were analyzed. Crashes were categorized by FHWA functional classification into three roadway groups: Interstates and Principal Arterials, Minor Arterials and Collectors, and Local Roads. Four spatial machine learning models, GXGBoost, SDT, GRF, and GeoKNN, were evaluated to classify crash severity outcomes, as traditional models do not account for the spatial dependence …

Perspectives On Civil And Social Peace In Palestine: Internal Factors And Forces That Obstruct Palestinian Civil Peace, Osama Tawfeeq Jarrar Dr., Prof. Ayman Talal Yousef Professor

Peace and Conflict Studies

The process of building “civil peace” is a dynamic process that aims at creating appropriate conditions of peace when conflicting forces, groups, and polices diverge. This concept is relative because it contains components that balance the internal and external environment, where peace-building is not undertaken in a historical or cultural vacuum, but rather works to develop comprehensive civic and national values: “The movement from the present toward the desired future is not a straight line, but rather a set of dynamic initiatives” (Lederach, 10). Civil peace entails social life as distinct from internal conflicts and tensions. Attaining civil peace thus …
