Evolving Community Preparedness: Analysis Of United States Pandemic Health Disaster Readiness, Jessy Rugeyo

Theses and Dissertations

The COVID-19 pandemic has shown substantial gaps in counties' preparedness and response capacity across the United States. This study analyzes the relationship between county-level pandemic preparedness and confirmed COVID-19 cases using secondary data from the FEMA's National Household Survey (NHS) and county-level COVID-19 data from the CDC. The data show a negative relationship between preparedness levels and COVID-19 positive rates, highlighting the necessity of proactive readiness measures. Individual risk assessment, motivation for preparedness, and socioeconomic variables have a major influence on confirmed cases. Higher levels of education, income, and preparedness are associated with lower positive rates, emphasizing the importance of …

Essays On Education And Labor Market Outcomes, Ishita Ahmed

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

This dissertation focuses on the labor market or educational outcomes using applied microeconomic methods. Chapter 1 investigates the impact of waiting an additional year to start kindergarten on the socioeconomic achievement gap in Nebraska using longitudinal administrative data from the Nebraska Department of Education. I utilize fuzzy regression discontinuity design to find the effect of waiting on test scores. I find waiting a year to improve the test score, and this impact fades away over time. This fading pattern shows a considerable amount of heterogeneity across different demographic groups, suggesting an acceleration of the achievement gap. The study also investigates …

Engaging Survivors In Transnational Justice Governance: Global, National And Local Perspectives From Uganda's Post Lra Insurgency, Dennis Jjuuko

Graduate Doctoral Dissertations

The end of the Second World War established the Nuremberg trials and the Tokyo tribunal while the United Nations (UN) system established ad-hoc tribunals in the former Yugoslavia and Rwanda, and multilateralism facilitated the creation of the present-day International Criminal Court (ICC). These trials and tribunals established liberal approaches to transnational justice governance. Despite the dominance of a liberal universalist justice framework, non-liberal justice approaches have also emerged. Considered as alternative customized justice structures, including South Africa’s Truth and Reconciliation Commission (TRC) and Rwanda’s Gacaca Courts, these community emergent approaches emphasize a transformative approach to addressing legacies of civil conflict …

Path-Choice-Constrained Bus Bridging Design Under Urban Rail Transit Disruptions, Yiyang Zhu, Jian Gang Jin, Hai Wang

Research Collection School Of Computing and Information Systems

Although urban rail transit systems play a crucial role in urban mobility, they frequently suffer from unexpected disruptions due to power loss, severe weather, equipment failure, and other factors that cause significant disruptions in passenger travel and, in turn, socioeconomic losses. To alleviate the inconvenience of affected passengers, bus bridging services are often provided when rail service has been suspended. Prior research has yielded various methodologies for effective bus bridging services; however, they are mainly based on the strong assumption that passengers must follow predetermined bus bridging routes. Less attention is paid to passengers’ path choice behaviors, which could affect …

How Housing Insecurity And Welfare Systems Retraumatize Women In Southern California, Yesika Menera

McNair Summer Research Program

Studies show that individuals experiencing homelessness and housing insecurity also experience trauma and mental illnesses. Despite this evidence, many resources provided through state welfare services seldom allocate sufficient funds and personnel to help address mental health. This study investigates the relationship between housing insecurity and trauma for adult women who have tried to access assistance throughout Southern California. To do this, I conducted in-depth interviews and DSM-5 questionnaires with twenty-six women during the summer of 2023 and 2024 via Zoom. My findings show that adult women who have experienced homelessness and housing insecurity in Southern California were more susceptible to …

Advocating For Data Access, Nathan D. Grawe

Numeracy

Participants in the numeracy movement have long recognized that an understanding of the social construction of quantitative evidence holds a place in the center of critical thinking about quantitative reasoning. Often, social construction manifests itself in choices about what should be counted and how. But an equally important choice is what data should be made available and to whom. As the movement matures, numeracy advocates must take their place alongside librarians in lobbying for broad access to basic data related to public policy.

The Political Thought Of Xi Jinping, Ian Forsyth

Joint Force Quarterly

Νot long after Xi Jinping assumed the post of General Secretary of the Chinese Communist Party (CCP) in November 2012, a debate among China-watchers emerged over the nature of Xi’s leadership. How ambitious was he? Would he try to change the norms of institutionalization that had existed since Mao Zedong’s death in 1976? What bureaucratic constraints would he face, and could he overcome them?

From Peril To Partnership: U.S. Security Assistance And The Bid To Stabilize Colombia And Mexico, Nerea M. Cal

Joint Force Quarterly

Recent scrutiny from Congress on U.S. military aid to Ukraine, Israel, and Taiwan has stimulated among both scholars and practitioners an increased interest in the topic of security assistance. One book that neatly bridges the gap between these two communities is Paul J. Angelo’s From Peril to Partnership. In this comprehensive and detailed account, Angelo conducts a comparative historical analysis of two multibillion-dollar security assistance initiatives—Plan Colombia in Colombia from 2000 to 2011 and the Mérida Initiative in Mexico from 2007 to 2016—to assess the effects of security-sector reform in different domestic contexts.

Five Truths For Foreign Area Officers, Michael L. Burgoyne, Albert “Jim” J. Marckwardt

Joint Force Quarterly

Colonel John Collins served in the U.S. Army through three wars and went on to be a revered military strategist and scholar. He founded the Warlord Loop, an organization of defense and security thinkers that remains active today. In 1987, Collins captured five “truths” regarding special operations forces. In so doing, Collins helped define the principles and attributes of special operations forces, which had been misunderstood by the larger conventional military. Foreign area officer (FAO) is another often misunderstood specialty in the military that would also benefit greatly from an exploration of its own truths. This is especially important given …

After Afghanistan: The Need For A New Noncombatant Evacuation Operation, E.R. "Elle" Klein

Joint Force Quarterly

With the noncombatant evacuation operation (NEO) in Afghanistan almost 3 years past and a NEO in South Korea an ever-present possibility, it is time to reevaluate the framework that governs the roles and responsibilities of Federal agencies in these life-and-death operations. What the Afghanistan NEO demonstrated—and what conflict on the Korean Peninsula bodes—is that the present framework buckles, if not collapses, under pressure. The United States must rethink the way it conducts NEOs if it is to properly protect noncombatant U.S. persons and allies in the increasingly unstable geopolitical terrain. This article argues that it is time for a new …

Was 50 Years Long Enough? The All-Volunteer Force In An Era Of Large-Scale Combat Operations, Kent W. Park, John A. Nagl

Joint Force Quarterly

Ιn an era of geopolitical competition among major powers, a large-scale war could last longer and result in more casualties than anything the United States has experienced since World War II. It is unclear whether the all-volunteer force (AVF) that the United States has relied on for the past 50 years, with extraordinary and unexpected success, can meet the manpower requirements in quality and quantity and in time to win the large-scale combat operations that the Department of Defense (DOD) is preparing for.

Deviance And Innovation: Change In A “Society Of Saints”, Thaddeus V. Drake, Derrick L. Mcclain

Joint Force Quarterly

Μilitary innovation and adaptation studies are a growth industry. Since the publication of Barry Posen’s seminal study The Sources of Military Doctrine in the early 1980s, the field has grown extensively. Despite well-known military thinkers’ recent book-length treatments of the topic, most studies of change in the military retain two key commonalities. First, nearly all assume that innovation or adaptation is inherently good and worth pursuing. Second, they agree that militaries are famously resistant to change and accept this as part of the fundamental nature of the military system. This article acknowledges the first point; indeed, modern military leaders continually …
