Gender And The Enactment Of Suicide Bombings By Boko Haram, Jordan N. Galehan

Dissertations

The Boko Haram terror group has utilized more women as suicide bombers than any other group in history. While prior research has examined why this phenomenon is occurring, and what makes Boko Haram a unique terror group, the present study examines how these attacks are being perpetrated, or enacted, by the female bombers. Utilizing the Global Terrorism Database (GTD), which is the largest terrorism incident database available, the study examined the incidents of female suicide bombings perpetrated by Boko Haram. The open-sourced citations provided by the GTD were compiled and turned into a complementary qualitative dataset. Overall, there were 151 …

Piezoelectric Energy Harvesting Via Frequency Up-Conversion Technology, Amin Abedini

Dissertations

Ambient energy harvesting has attracted significant attention over the last years for applications such as wireless sensors, implantable devices, health monitoring systems, and wearable devices. The methods of vibration-to-electric energy conversion can be included in the following categories: electromagnetic, electrostatic, and piezoelectric. Among various techniques of vibration-based energy harvesting, piezoelectric transduction method has received the most attention due to the large power density of the piezoelectric material and its simple architectures. In contrast to electromagnetic energy harvesting, the output voltage of a piezoelectric energy harvester is high, which can charge a storage component such as a battery. Compared to electrostatic …

The Archaeology Of Mississippian Vulnerability And Resilience In The New Madrid Seismic Zone, Michelle Megan Rathgaber

Graduate Theses and Dissertations

This work examines the vulnerability and resilience of Mississippian people in the Central Mississippi Valley to the large-scale New Madrid seismic zone earthquakes of the late15th to early 16th century. This is done using the theory of eventful archaeology/anthropology to look at cultural materials both before and after an event (such as an earthquake and sand blows) to look for evidence of changes to the schema and resources on which a society relies. If changes are present, the event can be labeled as such, if there are no changes, it means that the society affected did not see the event …

"Queen Of Kings": Masculinity And Femininity In The Visual Rhetoric Of Cleopatra Vii And Augustan Distortions Thereof, Allen Alexander Kendall

Theses and Dissertations

To address every aspect in which Cleopatra VII asserted her right to rule and maintain the favor of her own subjects and of Rome would be far too large a task for anything less than a book-length treatment. Rather than attempt to address multiple issues, this thesis addresses just one aspect of Cleopatra's political strategy to visualize her legitimacy as ruler: namely a combination of masculine and feminine elements in her iconography. This thesis will then follow the same themes in elements of Cleopatra's visual rhetoric was seized upon by the poets of Augustan Rome, who used it to the …

Measuring Racial Microaggression In Medical Practice, Amanda Lee Almond

Publications and Research

The purpose of the present study was to validate the already existing Racial Microaggression in Counseling Scale (RMCS) when the term “therapist” was replaced with “physician”, thus constituting the modification as the Racial Microaggression in Medical Practice Scale (RMMPS). Racial microaggressions work at reinforcing inferior social status on a cognitive level. Unlike overt racism, messages behind microaggression are subtler and more every day. A lack of acceptance, respect, and regard emerges from interactions in medical contexts as there are layers of in-group and out-group statuses at play (e.g., physician-patient, Black-White, expert-lay, and Westernized-alternative). The layer focused on in the present …

A Comprehensive Evaluation Of Predictive Performance Of 33 Species Distribution Models At Species And Community Levels, Anna Norberg, Nerea Abrego, F. Guillaume Blanchet, Frederick R.

Faculty Publications

A large array of species distribution model (SDM) approaches has been developed for explaining and predicting the occurrences of individual species or species assemblages. Given the wealth of existing models, it is unclear which models perform best for interpolation or extrapolation of existing data sets, particularly when one is concerned with species assemblages. We compared the predictive performance of 33 variants of 15 widely applied and recently emerged SDMs in the context of multispecies data, including both joint SDMs that model multiple species together, and stacked SDMs that model each species individually combining the predictions afterward. We offer a comprehensive …

The Prey Drive Model Of Sexual Violence, Tiffany Dawn Russell

Theses and Dissertations

The current project introduced prey drive theory, a new conceptualization of human violence perpetration adapted from canine training and breeding literature. As with canines, prey drive theory conceptualizes human aggression as a manifestation of genetically predisposed dominance and competitiveness. To evaluate the concept of human prey drive, the current study developed a prey drive model of sexual violence that was tested within a community sample of men (N = 662). Four latent trait clusters formed the foundation of the model: sexualized prey dominance, sexualized prey pursuit, antagonistic preparedness, and malevolent personality. A new scale, the Masculine Dominance Index, was …

On The Measurement Of Energy Dissipation Of Adhered Cells With The Quartz Microbalance With Dissipation Monitoring, Amir Monemian Esfahani, Weiwei Zhao, Jennifer Y. Chen, Changjin Huang, Ning Xi, Jun Xi, Ruiguo Yang

Department of Mechanical and Materials Engineering: Faculty Publications

We previously reported the finding of a linear correlation between the change of energy dissipation (ΔD) of adhered cells measured with the quartz crystal microbalance with dissipation monitoring (QCM-D) and the level of focal adhesions of the cells. To account for this correlation, we have developed a theoretical framework for assessing the ΔD-response of adhered cells. We rationalized that the mechanical energy of an oscillating QCM-D sensor coupled with a cell monolayer is dissipated through three main processes: the interfacial friction through the dynamic restructuring (formation and rupture) of cell-extracellular matrix (ECM) bonds, the interfacial viscous damping by the liquid …

Release Kinetics Of Methylene Blue In Pluronic F-127 Hydrogel, Meredith Hayden

Animal Science Undergraduate Honors Theses

“Between January 1998 and March 2000, veterinarians at the ASPCA National Animal Poison Control Center (NAPCC) consulted on more than 1,050 cases of accidental exposures to acetaminophen and 1,100 cases of ibuprofen ingestion in dogs and cats” (Richardson, 2000).

NSAID toxicity has become an increasingly common occurrence in small companion animals within the last decade due to widespread usage (Zhou, Boudreau, & Freedman, 2014). Depending on the specific drug, treatment is centered around early decontamination and prevention of kidney and hepatic damage, and methemoglobanemia. Currently, methemoglobanemia is treated with intravenous delivery of methylene blue and less commonly through oral administration. …

The Idea Of Property: A Comparative Review Of Recent Empirical Research Methods, Paul T. Babie, Peter D. Burdon Mr, Francesca Da Rimini, Cherie M. Metcalf Prof., Geir Stenseth

Indiana Journal of Global Legal Studies

While theory offers important insights into property's normative content, it sometimes fails to tell us about what people understand property to mean and how they interact with those things said to be owned by them. This has significant implications for some of the challenges facing humanity, including climate change, unequal distributions of wealth and resources, biodiversity loss, and innovation. In response, a growing body of literature is emerging that looks at property through a different lens; rather than theorizing property in an abstract way or attempting to craft a normative account of and justification for the institution, this new scholarship …

Impacts Of A Natural Disturbance On Coral Reefs In The Florida Keys And Subsequent Recovery Potential Of The Sea Urchin Diadema Antillarum, Julia Nicole Kobelt

Theses, Dissertations and Culminating Projects

Ecosystem resilience is a measure of an ecosystem’s capacity to resist abrupt change and recover following a disturbance. While stochastic disturbances can contribute to normal ecosystem functioning, mounting natural and anthropogenic stressors are simultaneously intensifying the severity of disturbances and reducing the capacity for ecosystem recovery. Here, I examine the impacts of hurricane disturbance on a coral reef ecosystem and the potential for post-storm population recovery of a keystone herbivore, the sea urchin Diadema antillarum. Grazing pressure exerted by dense populations of D. antillarum is critical to coral reef ecosystem health by preventing (or reversing) an ecological regime shift from …

Microbial Community, Functioning, And Its Relationship With Heavy Metals In An Urban Brownfield, Jay Prakash Singh

Theses, Dissertations and Culminating Projects

The ubiquity of urban brownfields presents a challenge for environmental managers for managing degraded ecosystems that are in close contact with human habitation. Presence of metal contaminants in brownfields further complicate the matters as it cannot be degraded and hence pose a high risk to human and environmental health, and well-being of the local community. However, previous studies indicate that management and restoration of brownfields are possible through the use of low input longer term and sustainable remediation approaches. These sustainable approaches include the use of plants, fungi, and bacteria to increase soil function and mitigate risks from the contaminants. …

Predictive Biomarkers Demonstrating The Effect Of Levels Of Copper And Zinc From Exposure To World Trade Center 9/11 Particulate Matter On Human Esophageal Cells In Vitro, Rossara Nunez

Theses, Dissertations and Culminating Projects

The World Trade Center Attack on September 11th, 2001 was the largest environmental attack that has ever happened in New York City. In the aftermath of the collapse of the twin towers, many first responders and rescue workers were exposed to the resulting clouds of dust. This toxic material has been shown to be responsible for membrane damage in human lung cells and can possibly become the cause of increased oxidative stress. The underlying factors that produce these findings are thought to the synergistic effects of the many components found within the market street sample. Complete analysis of the heavy …

Examining A Hypothyroid Model Of Depressive Symptoms In Mice: Tests Of Behavioral Measures, Hannah S. Ovadia

Theses, Dissertations and Culminating Projects

There is abundant evidence suggesting that Major Depressive Disorder (MDD) is closely related to thyroid hormone (TH) function, but the exact nature of this relationship is poorly defined in the literature. The present study examined whether hypothyroidism could viably model symptoms of MDD in mice using established behavioral paradigms. It was expected that hypothyroidism would produce anhedonia-like behavior in the saccharin preference test, anxiety-like behavior in the elevated plus maze, and spatial memory impairment in the object placement task. C57BL/6J mice were randomly assigned to one of three groups, which received either a control diet, diet infused with 6-propyl-2-thiouracil (hypothyroid …

Characterization Of Red Mangrove Proproot Epibiont Communities Of St. Johns Usvi, Alan M. Buob

Theses, Dissertations and Culminating Projects

In May 1989, Hurricane Hugo impacted St. Johns USVI destroying the Red Mangrove (Rhizophora mangle) Forest of Great Lameshur Bay. The impact restricted the tidal flow and caused massive destruction in the mangroves. Hurricane Marilyn (1995) hit St. John causing the storm wall formed by Hugo to be washed out. It returned limited tidal flow to the dead forest. It was not until a subsequent hurricane in 2010 broke down the sediment wall and natural flow returned. Up to that point, water quality restricted any fouling organisms’ survival on the prop roots. By using photo identification, three different bays of …

Indole-3-Glycerol Phosphate Synthase Ligand Binding Interactions, Oshane Thomas

Theses, Dissertations and Culminating Projects

Indole-3-glycerol phosphate synthase (IGPS) catalyzes the irreversible ring closure of 1-(ocarboxyphenylamino)- 1-deoxyribulose 5- phosphate (CdRP) into indole-3-glycerol phosphate (IGP) during the fourth step in tryptophan biosynthesis. Analysis of the crystal structure of IGPS from Mycobacterium tuberculosis (MtIGPS) hinted the importance of Lys119 for binding or catalysis. Lys110 from sulfolobus sulfataricus IGPS (ssIGPS) that aligns with Lys119 from MtIGPS, was proposed to be a general acid for the proton transfer that initiates the ring closure and decarboxylation of CdRP. To study the importance of Lys119 in the chemical mechanism for MtIGPS, an amino acid change was made at this position to …

Exploring The Role Of Evaporation And Precipitation Rates On Mangrove Island Morphology, Isamar M. CortéS

Theses, Dissertations and Culminating Projects

Mangroves are salt tolerant species of trees that grow in tropical and subtropical environments. Mangroves provide ecosystem services to societies along marine environments, including storm protection, coastal biodiversity, and blue carbon storage. However, as the importance of mangrove ecosystems has become clearer over recent years, their coverage has been reduced through mismanagement and climate impacts. For instance, in terms of climate warming, mangroves cannot survive under abnormally high rates of net evaporation when soil stressor concentrations (e.g., sulfate, sulfide) increase above threshold conditions. To study the effects of this climate driver phenomenon on mangrove islands, we are examining mangrove islands, …

The Effects Of Active Site And Allosteric Residues On Catalysis And Inhibitor Selectivity In The Bacillus Stearothennophilus Dihydrofolate Reductase, Tyler Eck

Theses, Dissertations and Culminating Projects

In drug discovery, building a comprehensive picture of the binding events between a drug and its enzyme target can be useful, especially in the development of new drugs or predicting the effect of a drug on a similar target from the same protein family. It is well known that a drug's selectivity is influenced by its interactions with amino acid residues within the active site, but contributions from residues situated away from (distal to) the active site are less well understood. Using a novel predictive approach PAnPredictor that employs sequence alignments, we have previously predicted residue positions in the dihydrofolate …

Examining The Role Of Epistemic Cognition In Teacher Learning And Facilitation Of Inquiry Dialogue, Sirine Mabrouk-Hattab

Theses, Dissertations and Culminating Projects

In this study, I investigated how a fifth -grade teacher engaged in epistemic cognition when he learned and facilitated inquiry dialogue. Inquiry dialogue is a type of talk in which participants use argumentation to search for the most reasonable answer to a contestable question. It has been suggested to represent the normative dialogue type to enhance students’ reasoning, as it is most aligned with the standards and practice of rigorous argumentation. Despite its importance, researchers have shown that it has not been widely implemented in classrooms and this is partly due to teachers’ epistemic cognition. Given the significance of inquiry …

Current Perspectives Into The Evaluation And Management Of Hepatitis B: A Review., Vignan Manne, Eric Gochanour, Kris V Kowdley

Articles, Abstracts, and Reports

Hepatitis B is a widespread disease which affects millions of people worldwide. Chronic hepatitis B (CHB) can lead to significant morbidity and mortality due to complications such as cirrhosis and hepatocellular carcinoma. The pathophysiology of hepatitis is critical to diagnosing CHB. Deciding which patients with CHB should be treated is an important decision as treatment can often lead to better outcomes in the appropriate patient population. The nucleos(t)ide analog inhibitors entecavir and tenofovir are currently the mainstay of treatment as they are able to successfully suppress the virus and lead to fewer complications. Novel therapies are currently being developed which …

The Influence Of Mir-322 On Skeletal Muscle Differentiation, Miles Alexander Soyer

Legacy Theses & Dissertations (2009 - 2024)

Skeletal muscle plays a crucial role in coordinating voluntary movement and accounts for nearly 50% of total body mass. Dysregulation in skeletal muscle development is known to cause muscle degenerative diseases including the devastating Duchenne Muscular Dystrophy (DMD). The majority of the biological studies investigating muscle development were based on myogenic transcription factors and signaling molecules including: Pax7, Myf5, MyoD, WNT, TGF-β and BMP. After the discovery of non-coding RNAs including microRNAs, it was postulated that these molecules could regulate gene expression and thus affect differentiation and development. MicroRNAs are small non-coding RNAs (~17-25 nucleotides) that regulate gene expression negatively …

Comparison Of Gait Kinematic And Temporospatial Measures Between Lock And Pin And A New Vacuum Suspension System In Transtibial Amputees, Vanessa A. Kellems

Master's Theses

Walking in healthy populations has been characterized by symmetrical gait patterns and used to determine variability within pathological populations. Gait patterns of individuals with transtibial amputation are commonly asymmetrical due to the inability to completely replicate the physiological ankle with prosthetics; thus, contributing to inter-limb asymmetries. Currently, only a few studies have reported the effects of suspension systems on gait mechanics. In this study, functional differences between lock and pin (PIN) and a newly developed internal vacuum suspension system (Smart PUCKTM) (PUCK) during overground and treadmill walking were evaluated in five transtibial amputees. Statistically, no differences were found between groups …

Stem Heroes: A Narrative-Based Intervention To Increase Self-Efficacy And Interest In Science, Technology, Engineering, And Mathematics In Elementary School-Aged Children, Lauren M. Carino

Seton Hall University Dissertations and Theses (ETDs)

Over time, researchers have struggled to identify effective interventions to support girls’ self-efficacy and interest in science, technology, engineering, and mathematics (STEM). The primary purpose of this study was to examine whether a theoretically-grounded narrative-based intervention would be able to increase elementary school-aged girls’ self-efficacy in respect to future careers and interest in STEM subjects in school. The study sought to do this by using the stories of the “Heroes of STEM”, a series of four graphic novels developed by the principal researcher, as an intervention tool linking girls’ typically preferred subject (i.e., reading, language arts) to math and science. …

Data Philanthropy, Yafit Lev-Aretz

UC Law Journal

The term “data philanthropy” has been used to describe the sharing of private sector data for socially beneficial purposes, such as academic research and humanitarian aid. The recent controversy over an academic researcher’s alleged misuse of Facebook users’ data on behalf of Cambridge Analytica has brought data philanthropy into the spotlight of public debate. Calls for data ethics and platform transparency have highlighted the urgent need for standard setting and democratic oversight in the use of corporate data for public ends. Data philanthropy has also received considerable scholarly attention in various academic disciplines but has, until now, been virtually overlooked …

Synthesizing Multifunctional Iron Oxide Nanodrugs And Developing A Model For Their Size Analysis Using Dynamic Light Scattering, Olivia George

Honors Theses

The growth of targeted drug delivery methods in modern cancer treatments has been the result of an increase in the quantity of drugs available, which is directly affected by the methods used in drug development. These drugs vary in size, shape, and mechanism of operation, so the characterizing techniques used must be adaptable to a variety of particle types. In this thesis, a variety of complex nanostructures were synthesized and characterized using dynamic light scattering (DLS), which is a rapid, non-destructive, and simply-operated size characterization method that does not introduce artifacts from sample preparation. The DLS data was then analyzed …

Inequality, Patronage, Ethnic Politics And Decentralization In Kenya And Botswana: An Analysis Of Factors That Increase The Likelihood Of Ethnic Conflict, Rei Gordon

Masters Theses

Scholars have recommended numerous institutional arrangements for mitigating ethnic conflict in divided societies. Electoral systems are often considered to have an impact on ethnic conflict, and scholars have recommended both proportional representation systems and majoritarian systems for their respective effects on mitigating ethnic tensions. However, in a cross-national analysis of 18 sub-Saharan democracies, I find no impact of electoral systems on ethnic conflict. Countries employing proportional representation systems and majoritarian systems are compared according to three measures of ethnic conflict, yet neither electoral system correlates with higher or lower levels of conflict. In the interest of identifying factors that do …
