Ethnic Conflict In Côte D’Ivoire, Ayouba Doumbia

Dissertations and Theses

Since the early days of independence, the African continent has been the theatre of many ethnic conflicts. While people, in general, assume these conflicts to be political and blame the conflicts on authoritarian regimes, they dismissed the fact that conflict between ethnicities is a phenomenon that has occurred for hundreds of years and in all corners of the Earth. Entire countries have been devastated by years of ethnic strife. Once ethnic conflict breaks out, it is difficult to stop. Conflicts in the Balkans, Rwanda, Chechnya, Iraq, and Darfur are among the deadliest examples from the late 20^th and early …

Exploring A Mediational Model Of The Relationship Between Skin Color And Mate Selection In Desi Young Adults, Rabiya Ahmed

Dissertations and Theses

Skin color bias is present in South Asia and is especially apparent within the Desi (i.e., South Asian) marriage market, where explicit preferences for fair-skinned marital partners are made and lighter skin is perceived as more attractive. It is also known that, through the halo effect, attractive people are perceived to possess positive personality traits. The present study aimed to determine if skin color is associated with long-term mate preference among U.S.-based Desi adults as it is among Desi in South Asia, and if so, if that relationship is mediated by perceived attractiveness. It also aimed to determine if, in …

Timing Of Sexual Minority Identity Developmental Milestones And Well-Being Among Three Generations Of Gay Men, Joseph R. Hillesheim

Dissertations and Theses

Social and political changes during recent decades have contributed to a more accepting environment for sexual minorities (non-heterosexual individuals) in the U.S., but recent evidence suggests that these shifts may create a “developmental collision” for younger generations (Meyer et al., 2021; Russell & Fish, 2019). Younger generations of sexual minorities “come out” and reach other sexual identity milestones earlier than older generations, and earlier timing of sexual identity development may contribute to increased vulnerability to stigma. The present study aimed to contribute to limited research on the relationship between the timing of sexual identity development milestones and well-being among three …

China In Africa: Partner Or Exploiter? The Case Of Zambia, Chansa E. Mushota

Dissertations and Theses

Marked by investments, loans, and finance, China’s engagement in Africa has grown swiftly. Amongst sub-Saharan Africa’s many trading and developing partners, China remains the biggest partner and investor with an increase in trade relations.^[1] The China-Africa relationship has brought significant economic opportunities, but it has also generated controversy in the international community. China has been challenged by some of forming a partnership with African governments solely for China’s own interests. China provides low-interest loans to the African governments for development and infrastructure projects. However, China’s motives are exploitative as China uses economic and political pressures to influence African governments …

Protecting Civilians In Un Peace Operations: The Need For Enhanced Training, Allison S. Haddad

Dissertations and Theses

The present study shows that the protection of civilians (POC) tasks implemented in multiple United Nations (UN) peace operations have not always been executed as intended and, as a result, are accompanied by a number of dysfunctions. Among these dysfunctions are inadequate community engagement, peacekeeper misconduct stemming from the lack of proper training mechanisms, and lack of resources. In consideration of these issues, UN peace operations would profoundly benefit from enhancements offering plausible and beneficial change to the field. Such changes involve the responsibility of the UN, the responsibility of national actors, field implementations, and the psychological well-being of peacekeepers. …

Therapist Feelings Of Incompetence: Their Relationship To The Working Alliance And Treatment Outcome., Benjamin Bernstein

Dissertations and Theses

This study set out to explore therapist feelings of incompetence (FOI) in the therapeutic process from both a quantitative and qualitative perspective. While previous studies have explored therapist descriptions of such feelings, this is among the first attempts to look at the role of these specific feelings in an individual therapy session using therapist and patient data. The results revealed that therapist feelings of incompetence impact the working alliance directly and outcome change indirectly, through the working alliance. Furthermore, qualitative analysis suggested that therapist feelings of incompetence might be associated with specific avoidant behaviors which may negatively impact the working …

Adsorption Kinetics And Phase Behavior Of Particles Adsorbed At An Interface, Shaghayegh Darjani

Dissertations and Theses

The ability to predict the adsorption dynamic, phase behavior, and surface pressure of a monolayer of adsorbed particles in two-dimensional systems are key aspects of many current research areas. Examples include phase transitions in amphiphilic monolayers, emulsion stability due to particle adsorption at interfaces, and melting at an interface.

In this thesis, a new approach for deriving the equation of state for a two-dimensional lattice gas is proposed, based on arguments similar to those used in the derivation of the Langmuir-Szyszkowski equation of state for localized adsorption. This work aims to predict the adsorption kinetics and phase behavior of a …

Restoration Of Bone Material And Microstructural Properties After Long-Term Remodeling Suppression, Abigail A. Coffman

Dissertations and Theses

Anti-resorptive drugs, principally bisphosphonates (BPs), are the mainstay of osteoporosis treatment. They work by inhibiting bone resorption/remodeling, thus preventing bone loss. However, long-term suppression of bone resorption adversely affects bone tissue mechanical properties, even while conserving bone mass. Lack of remodeling leads to accumulation of fatigue-induced microdamage, altered matrix mineralization and reduction in normal bone tissue heterogeneity, causing impaired strength and fracture toughness. The most severe consequence to patients, while rare, is Atypical Femur Fractures (i.e., complete fatigue fractures of the femoral shaft). To counteract the effects of long-term remodeling suppression, a temporary break in BP treatment (a "drug holiday) …

A New Mathematical Theory For The Dynamics Of Large Tumor Populations, A Potential Mechanism For Cancer Dormancy & Recurrence And Experimental Observation Of Melanoma Progression In Zebrafish, Adeyinka A. Lesi

Dissertations and Theses

Cancer, a family of over a hundred disease varieties, results in 600,000 deaths in the U.S. alone. Yet, improvements in imaging technology to detect disease earlier, pharmaceutical developments to shrink or eliminate tumors, and modeling of biological interactions to guide treatment have prevented millions of deaths. Cancer patients with initially similar disease can experience vastly different outcomes, including sustained recovery, refractory disease or, remarkably, recurrence years after apparently successful treatment. The current understanding of such recurrences is that they depend on the random occurrence of critical mutations. Clearly, these biological changes appear to be sufficient for recurrence, but are they …

Mira Muchacha: The Latinx Bildungsroman In Elizabeth Acevedo’S The Poet X, Layza M. Garcia

Dissertations and Theses

This thesis explores how the Bildungsroman’s traditional narrative transforms into a window to the Latinx experience in Elizabeth Acevedo’s The Poet X. The traditional Bildungsroman features white, male, and European protagonists, according to Louis F. Caton in “Romantic Struggles: The Bildungsroman and Mother-Daughter Bonding in Jamaica Kinclad’s Annie John” (126). Recognized as the first work in the Bildungsroman genre, Johann Wolfgang von Goethe’s Wilhelm Meister’s Apprenticeship (1796) tracks the development and education of the protagonist from boyhood to manhood. In 20th and 21st century literature, the Bildungsroman structure expands to reflect the diverse cultures, lifestyles, and identities of its readers. …

Disaster And Hope In The Comic Universe Of 'Gardening In The Tropics', Molly Mosher

Dissertations and Theses

In this paper, I explore ideas of dominion and how Western canon has helped propagate ideas of human domination of the natural world. Using Joseph W. Meeker’s The Comedy of Survival, I trace a line from the advent of the literary tragedy to the climate crisis. To contrast, I use his idea of comedy as the antidote to domination — a way of thinking that might inspire collaboration with the natural world. I will explore the comic with, predominately, Olive Senior’s Gardening in the Tropics, alongside Jamaica Kincaid’s gardening studies and Mona Lisa Saloy’s essay on environmental destruction. To …

Roberto Bolaño’S 2666, The Funneling Effect Of Capitalism, And The Production, Consumption, And Proliferation Of Violence For Profit, John Timlin

Dissertations and Theses

Roberto Bolaño's novel 2666 is a realist text, one that reflects the simple fact that in contemporary capitalism, the physical destruction of female bodies is a profitable enterprise; one that forces its readers to confront their complicity or outright participation in violence against women; and one that relates directly to violence against women as consumable entertainment in American mass culture.

Henry Adams: An Education In Autobiography, Marcellus Richie

Dissertations and Theses

This essay will begin by breaking down Henry Adams’s starting sentence in his autobiography word by word, piece by piece – pondering its meanings and permutations in the context of subsequent chapters of this iconic memoir. The essay will then consider whether Adams’s Education should still be regarded as a classic of American autobiography or seen merely as an irrelevant and out-of-date artifact. In a nation radically transformed since Adams’s time, does the book still deserve its high flung reputation? In other words, which of the images cited above is most relevant to The Education: an image of optimistic youth …

The Jamaican Maroons Of The 17th And 18th Centuries: Survivalists Of The New World, Lance J. Parker Jr

Dissertations and Theses

The Jamaican Maroons, in the beginning, served as fugitive slaves avoiding captivity and liberating other enslaved people. To stop the Maroons from liberating other enslaved people, the British granting them freedom on the condition that they stop freeing slaves and even return runaways. Historians portray the Maroons as either freedom fighters or collaborators, sometimes even both. I argue that both narratives were a part of Maroon history, but I want to introduce them as survivalists. My research's significance is that I am exploring how the Maroons transitioned from freedom fighters to collaborators through notions of cultural identity. This project aims …

The Space Between “Seen” And “Unseen:” Queer People And The 1915-1945 New Negro Renaissance, Claudia R. Campanella

Dissertations and Theses

In November 1926, a group of Black artists, writers, and activists created the first and only edition of Fire!!, edited by novelist Wallace Thurman. Fire!! was created by a younger generation of New Negroes and “devoted to the younger Negro artists” who dissented from the mainstream ideas of the New Negro Movement and used the magazine to spread their own views on the 1915-1945 New Negro Renaissance. Fire!! and other texts speaking to this dissent against a Black intellectual middle class image of the movement will be studied in reference to showcasing the multi-faceted elements of the movement touching …

Dynamics Of Simultaneous Nitrite Ion And Ammonia Chlorination In Complex Water Quality Matrices And Their Impact On Chlorine Residual Speciation During Disinfection, Shirin Estahbanati

Dissertations and Theses

Although chlorination of ammonia and nitrite ions have been studied comprehensively, the kinetics of chlorination in water matrices containing ammonia in the presence of nitrite ion have not been fully understood. The coexistence of the two nitrogen compounds is a phenomenon most often encountered during biological nitrification of municipal wastewaters. The spatial variation of the nitrogen species generates unpredictable complications in the effectiveness of chlorination as the disinfection process. The focus of the research study was the examination of chlorine residual speciation and the fate of ionic nitrogen species, i.e. nitrite and nitrate ions, under various experimental conditions. The experimental …

Molecular And Genetic Studies On A Sipd/Ipad-Related Virulence Spike Protein From Immune-Suppressive Particles Of A Drosophila Parasitoid, Carlo Miguel A. Sevilla

Dissertations and Theses

Parasitoid wasps are effective biological control agents that have evolved intricate host immune suppression strategies to overcome host immune defenses. The most important anti-parasite defense mechanism is encapsulation, where the host’s blood cells surround the wasp egg. In the Drosophila/Leptopilina host-parasitoid system, extracellular vesicles (EVs) are oviposited along with the wasp egg. The EVs possess spikes and contain hundreds of proteins, some of which enable wasp eggs to escape encapsulation by changing the morphology and function of hemocytes, or killing them. Previous studies have identified an abundant surface/spike protein (SSp40) from Leptopilina heterotoma EVs. While p40, a predicted …

The Intersectional Perspective On Women And Girls With Disabilities: A Comparative Analysis, Kathryn F. Guzmán

Dissertations and Theses

People, including women and girls with disabilities have faced oppression and exclusion in society for centuries due to negative beliefs, stereotypes and attitudes that have led to stigma, discrimination and lack of support for them. For women and girls in particular, having a disability has historically meant that they were no longer considered beautiful and were seen as being incapable of meeting social and cultural expectations like marriage and motherhood. In recent decades, however, some progress has been made towards combating disability-based discrimination and promoting inclusion and full participation in society. Additionally, the adoption of the United Nations Convention on …

Analyzing Ultrastructural Characteristics Of Post-Synaptic Targets Of Pre-Identified Presynaptic Boutons In Layer 3 And Layer 4 Of The Ferret Primary Visual Cortex, Donia Shehab

Dissertations and Theses

The purpose of this study was to analyze the size and ultrastructural characteristics of post-synaptic elements apposed to previously characterized pre-synaptic elements in layers 3 and 4 of the primary visual cortex (PVC). We are aiming to quantify a range of values for synaptic element morphologies as well as to correlate pre- and post-synaptic elements to find a set of rules that is prevalent in the visual cortex that can also be upheld in other mammals. We hypothesize that bigger pre-synaptic elements correlate to bigger synapses and bigger post-synaptic elements. We compared these two different layers because they receive synaptic …

Reassessing The Ranging Behavior Of Black-And-White Ruffed Lemurs (Varecia Variegata) In Ranomafana National Park, Madagascar, Jelisa R. Oliveras

Dissertations and Theses

This study investigates black-and-white ruffed lemur (Varecia variegata) space use and movement using autocorrelated kernel density estimation (AKDE), a new methodology available from the continuous-time movement model (ctmm) package in R. Data were collected from 24 adults and subadults (10 males, 11 females, 3 subadult males) living in two adjacent V. variegata communities at Mangevo bush camp in Ranomafana National Park, Madagascar (RNP) for 11 months (February – December 2008) to estimate annual and seasonal patterns of individual and community-level range use. Autocorrelated kernel density estimates generated in this study are compared to earlier kernel density estimates from …

The Impact Of The International Monetary Fund’S 2016 – 2019 Loan To Egypt On The Country’S Development, Anasimon Takla

Dissertations and Theses

The primary objective of the International Monetary Fund (IMF) is growth. The organization and its programs can enable the development of nations across the globe and stimulate growth. However, due to weaknesses in its system with conditions that are offered as blanket solutions for unique problems as well as unequal bargaining terms, the IMF can exacerbate the situation in nations that are already suffering with crises. Following years of unrest after the Arab Spring, Egypt finds itself in an unwieldly position having both vowed to increasing its development as well as introduced major reforms based on IMF recommendations in order …

The Push Factors That Impact Sex Trafficking In The Former Soviet Union, Liliya Kenzhebayeva

Dissertations and Theses

Sex trafficking is a global problem that has been denounced by the international community as a human rights abuse and determined to be a modern form of slavery. Through a comparative analysis of the experiences of Kazakhstan, Russia, and Ukraine as they were a part of the Soviet Union the study identifies the push factors of sex trafficking in women as forced labor with particular emphasis on the role of weak legal systems and state institutions, corruption, social and economic factors, and environmental problems that are linked to organized crime (the Russian mafia) from 2001 to 2019. The thesis supports …

The World’S Leading Regulator: Why Countries Must Abide By The European Union’S Strict Chemical Laws And What That Means For Its Closest Trading Partners, Matthew Silberger

Dissertations and Theses

The European Union is the world’s leading regulator, imposing strict laws on all sectors of industry including chemical manufacturers. The bloc’s programs imposing these strict chemical regulations are entitled Restriction of Hazardous Substances Directive (RoHS) and Registration, Evaluation, Authorization and Restriction of Chemicals, or REACH. These laws are imposed to ensure that the chemicals present in products are properly recorded and to ensure the health and safety of citizens and the environment. This thesis will discuss the role the European Union plays in the world regarding the chemical industry and how countries modify their own regulations to ensure their companies …

A Snowball Effect: A Pandemic’S Impacts On Household Food Insecurity In The United States, Sidie Sahid Sisay

Dissertations and Theses

Economic insecurity exists whenever income sources are uncertain, and this is a failure of a fundamental human right. The Covid-19 pandemic has presented unprecedented disruptions to the US economy and has created unparalleled food insufficiency and economic hardships. Before the pandemic, household food insufficiency existed but downplayed in the political arena. In 2019, 10.5 percent of households in the US lived in extreme poverty and were food insecure, the lowest since 1959, but the pandemic has had devastating effects on household food insufficiency. This paper uses nationally representative data from the Census Bureau’s weekly household pulse survey, coupled with standard …

Goes-R Supervised Machine Learning, Ronald Adomako

Dissertations and Theses

The GOES-R series is a product line of four satellite, with two currently on-orbit (GOES-16 “East” and GOES-17 “West”). GOES-17 is susceptible to a Loop-Heat-Pipe (LHP) phenomenon where during Fall and Spring seasons, there are times of day where some of the infrared bands records inaccurate readings from the Advanced Baseline Imager (ABI). This occurs from joint astronomical behavior and position of the GOES-17. This calibration issue occurs when the LHP instrument fails to radiate the heat of the sun out of ABI. Predictive Calibration (pCal) is an algorithm developed by instrument vendors for the National Oceanic Atmospheric Agency (NOAA) …

Blockchain-Based Architecture For Secured Cyberattack Signatures And Features Distribution, Oluwaseyi J. Ajayi

Dissertations and Theses

One effective way of detecting malicious traffic in computer networks is intrusion detection systems (IDS). Despite the increased accuracy of IDSs, distributed or coordinated attacks can still go undetected because of the single vantage point of the IDSs. Due to this reason, there is a need for attack characteristics' exchange among different IDS nodes. Another reason for IDS coordination is that a zero-day attack (an attack without a known signature) experienced in organizations located in different regions is not the same. Collaborative efforts of the participating IDS nodes can stop more attack threats if IDS nodes exchange these attack characteristics …

Molecular To Macroscopic Understanding Of Chloroaluminate Anion Intercalation In Rechargeable Aluminum-Graphite Batteries, Jeffrey Xu

Dissertations and Theses

Today’s global energy challenges pose an urgent need to electrify transportation and better store intermittent renewable energy sources (e.g., solar and wind energy). For such large-scale battery applications, aluminum batteries are a promising “beyond lithium-ion” technology due to the high volumetric capacity, earth abundance, low-cost, and inherent safety of aluminum metal. However, there are very few compatible positive electrode materials that exhibit high energy density and cycling stability, in part due to the challenges of electrochemically intercalating highly charged Al³⁺ cations. Recently, graphite has been demonstrated as a promising positive electrode material in non-aqueous rechargeable aluminum batteries, which store …

Structural Robustness Of Long-Span Cable-Supported Bridges, Qian Chen

Dissertations and Theses

As a critical part of the current infrastructure system, long-span bridges are directly exposed to adverse environments, such as floods, scours, hurricanes, etc., and dynamic loads such as earthquakes and vehicular impacts. Additionally, recent long-span cable-supported collapse examples show that many bridges suffered progressive collapse when local damage occurred, and they are highly vulnerable to severe damages in the event of a localized failure. However, the traditional design approaches are unable to provide explicit measures of residual safety of bridges, especially after an abnormal event. Currently available redundancy and robustness evaluation approaches, which were developed mainly for short-span bridges, are …
