A Network Theoretical Approach To Real-World Problems: Application Of The K-Core Algorithm To Various Systems, Kate Burleson-Lesser

Dissertations, Theses, and Capstone Projects

The study of complex networks is, at its core, an exploration of the mechanisms that control the world in which we live at every scale, from particles no bigger than a grain of sand and amino acids that comprise proteins, to social networks, ecosystems, and even countries. Indeed, we find that, regardless of the physical size of the network's components, we may apply principles of complex network theory, thermodynamics, and statistical mechanics to not only better understand these specific networks, but to formulate theories which may be applied to problems on a more general level. This thesis explores several networks …

Gender And Terrorism: A Homeland Security Perspective, Diana Rosa Rodriguez-Spahia

Dissertations, Theses, and Capstone Projects

While scholars have been studying the growing trend of female terrorists for several years, their research has not permeated politics or the media to help inform our Homeland Security policies. The findings from this body of research indicate that there is hesitance on behalf of the public (especially politicians and law enforcement) to acknowledge that women can be terrorists due to deeply engrained gender norms and expectations about gender roles. Terrorist groups are exploiting this unwillingness by recruiting more women to perpetrate terrorist acts (Lele, 2014; Bloom, 2011). Against the backdrop of the changes in gender norms and expectations that …

Diagnosing The Will To Suffer: Lovesickness In The Medical And Literary Traditions, Jane Shmidt

Dissertations, Theses, and Capstone Projects

Throughout Western medical history, unconsummated, unreturned, or otherwise failed love was believed to generate a disorder of the mind and body that manifested in physiological and psychological symptoms. This study traces the medical and literary history of lovesickness from antiquity through the 19^th century, emphasizing significant moments in the development of the medical discourse on love. The project is part of the recent academic focus on the intersection between the humanities and the medical sciences, and it situates literary texts in concurrent medical and philosophical debates on afflictions of the psyche. By contextualizing the fictional works within the scientific …

Ansiedades Épico-Criollas Y El Mecenazgo De Indias En El Arauco Domado De Pedro De Oña, Andrea L. Fernandez

Dissertations, Theses, and Capstone Projects

Among the characteristics of epic poetry are the topic of war, love encounters, heroism of exemplary individuals, and the narration of events contemporary to the audience to reinforce a collective historical identity. Arauco domado by Pedro de Oña, born in Angol (modern Chile), reiterates these traditional expectations with its protagonist, characters, setting, and latter theatrical representations within the viceregal context. The poem was made possible by the sponsorship of García Hurtado de Mendoza y Manrique, IV Marquis of Cañete and Viceroy of Peru. If the title of “espíritu cesarino novelo” [Caesar’s new spirit] (V.76.3) corresponds to the patron, Pedro de …

Synthesis And Characterization Of Cytocompatible Sponge-Mimetic Scaffolds And Biomedical Polymers, Kamia Punia

Dissertations, Theses, and Capstone Projects

This dissertation describes the novel synthetic methodologies towards: a) protein/polysaccharide intercalated sponge-mimetic scaffolds for 3D cell culture, b) peptide-mimetic cationic amphiphilic antibacterial polymers, and c) bioactive Poly(DL-lactide-co-glycolide) (PLGA) nanofibers by solution blow spinning for the treatment of cancer and traumatic wound care.

The classic “chemical garden” experiment is reconstructed to produce protein/polysaccharide (ingredients of cyanobacterial origin) intercalated silicate-phosphate tubules that resemble tubular sponges. The constructs were synthesized by seeding calcium chloride into a solution of sodium silicate-potassium phosphate and gelatin/polysaccharides. The morphology and composition of sponge-mimetic tubules were analyzed by a battery of techniques. Bioconjugation and coating protocols were developed …

Synthesis And Evaluation Of Densely-Functionalized Troponoids, Danielle R. Hirsch

Dissertations, Theses, and Capstone Projects

Herein, we document our efforts to expand the scope of troponoid synthetic methodology towards densely-substituted scaffolds. This body of work has focused primarily on an oxidopyrylium cycloaddition/ring-opening strategy for the synthesis and biochemical evaluation of troponoids for assistance in a variety of medicinal chemistry studies. In Chapter 1, we outline the use of this synthetic strategy in the profiling of a library of synthetic αHTs against an aminoglycoside antibiotic resistance enzyme known as aminoglycoside-2’’-O-nucleotidyltransferase [ANT(2’’)-Ia]. Enzymatic mechanistic insights have been gleaned from an assessment of troponoid/antibiotic synergistic potential. In particular, two synthetic constructs were identified as promising antibiotic adjuvant candidates, …

Wukongism: Monkey King, Kungfu/Jazz, And Asian/American Performance, Sissi Liu

Dissertations, Theses, and Capstone Projects

Wukongism offers one of the first non-western epistemic frameworks to examine theatre and performance that traverse beyond the shifting taxonomies of national, cultural, racial boundaries, and in particular, Asian/American theatre and performance. Wukongism, or shapeshifter consciousness, is built on the narrative of Sun Wukong the Monkey King, a supernatural shapeshifting character from the 16^th century classic Chinese novel Journey to the West. Juxtaposing physical shapeshifting (plastic surgery and performing of the racialized face) with institutional shapeshifting (reinventing and eliminating invisible and hypervisible boundaries), this dissertation project posits Wukongism as a means to examine the varying, fluid, and precarious …

This dissertation presents a description of the sound patterns of Kachok, Austroasiatic language spoken in northeastern Ratanakiri Province, Cambodia. The language is spoken by approximately 3000 people and is considered endangered (Simons & Fennig, 2018). Kachok is undocumented, and this dissertation is the first attempt to describe the language and its sound patterns. The goals of this dissertation are twofold: to contribute to linguistics and the science of phonetics and phonological typology, as well as increase the body of work on Austro-Asiatic languages, and to create resources for the Kachok language, culture, and people that have the potential to outlive …

Dietary Curcumin Promotes Resilience To Chronic Social Defeat Stress In A Highly Susceptible Mouse Strain, Antonio V. Aubry

Dissertations, Theses, and Capstone Projects

Chronic exposure to stress is a risk factor for the development of major depression and post traumatic stress disorder in humans and induces depressive- and anxiety-like phenotypes in rodents. However, there are few pharmacological interventions available that effectively treat maladaptive responses to chronic stress in the clinical setting. One therapeutic agent that has recently shown promise in treating psychiatric disorders is curcumin, a yellow-pigmented polyphenol compound found in the turmeric plant. Curcumin has been shown to prevent the development of stressed-induced depressive-like behavior in rodents and reduce symptoms of depression in clinically diagnosed patients. In this dissertation, I investigated whether …

"When We Demand Our Share Of This World”: Struggles For Space, New Possibilities Of Planning, And Municipalist Politics In Mumbai, Malav J. Kanuga

Dissertations, Theses, and Capstone Projects

This dissertation presents an urban history of Bombay/Mumbai from the perspective of a politics of plurality, arguing that while the city has emerged from governmental control and planning, its development has also been shaped by myriad popular productive forces of urban society. The dissertation traces the uneven development of the city through significant planning policies, popular movements, and lived experiences of various struggles against regimes of developmentalism—the governing ideologies of development, techniques, policies, and rules of law through which the city has been planned and governed. These ideologies and practices have shifted over time, but since the earliest days of …

The Upright Battle: Morphological Trends Of The Bipedal Pelvis, Nicole M. Webb

Dissertations, Theses, and Capstone Projects

The shift to bipedal locomotion is a distinguishing feature of the human lineage that required substantial remodeling of the postcranium in hominins. The pelvis, due to its important functional role as a stabilizing and weight-bearing structure, has undergone one of the most drastic transformations in the skeleton to accommodate obligate bipedalism, thus making it a valuable region for studying locomotor behavior within the fossil record. Although bipedalism occurs in several mammalian groups, it is rare within primates and the ability to utilize a striding gait with an erect, or orthograde, posture remains unique to hominins. Orthograde posture in this context …

The Politics Of Service: Affectivity, Social Relations, And The Power Of Tipping In The Restaurant Industry, Jacqueline A. Ross

Dissertations, Theses, and Capstone Projects

The #MeToo movement and the growing spotlight on sexual harassment and misconduct has increasingly brought industries and individuals into the public eye. The restaurant industry is one such industry to receive this spotlight. While most of the coverage has stemmed from celebrities, the misconduct of celebrity chefs has been paralleled by the stories of servers and their customers. The NY Times published several articles on harassment in the restaurant industry and some specifically focusing on the abuses that tipped workers face. Often these workers were women. When asked about experiences of harassment, responses were often that servers felt that they …

The Effects Of A Voice Treatment On Facial Emotional Expression In Parkinson's Disease: Expressivity, Experience, And Gender, Elizabeth M. Murray

Dissertations, Theses, and Capstone Projects

Individuals with Parkinson’s disease (PD) suffer from decreased ability to express emotion through facial expression, in what has been termed “masked facies” or hypomimia. Facial emotional expression is necessary for the accurate communication of needs, to obtain or maintain empathy from care-givers, and to be perceived by others in a way that matches the way that one feels. The current study provides a review of the deficits seen in Parkinson’s disease, an overview of the neurobehavioral disparity of spontaneous versus posed facial expression of emotion, and factors that influence the perception of emotion, such as gender and clinical variables. The …

The Labyrinth And The Cave: Archaic Forms In Art And Architecture Of Europe, 1952–1972, Paula Burleigh

Dissertations, Theses, and Capstone Projects

This dissertation examines the prevalence of spatial archetypes as potent symbols that manifested in art, architecture, exhibition design, and urban planning in the aftermath of World War II and into the Cold War. Owing to the dual influence of structuralism and phenomenology in French intellectual culture, many examples discussed here were produced in France or made by artists who spent significant time there. These figures include Jacqueline de Jong, Paul Virilio, Claude Parent, André Bloc, and the Groupe de Recherche d’Art Visuel (GRAV), all of whom made projects evoking speculative realities that oscillated between utopian and dystopian.

Given their focus …

Renal Risk Variants Of Apolipoprotein L-1 Form Channels At The Plasma Membrane That Lead To A Cytotoxic Influx Of Calcium, Joseph A. Giovinazzo

Dissertations, Theses, and Capstone Projects

Apolipoprotein L-1 (APOL1) is a secreted protein that provides protection against several protozoan parasites due to its channel forming properties. Recently evolved variants, G1 and G2, increase kidney disease risk when present in two copies. In mammalian cells, overexpression of G1 and G2, but not wild-type G0, leads to swelling and eventual lysis. However, the mechanism of cell death remains elusive with multiple pathways being invoked, such as autophagic cell death mediated by a BH3 domain in APOL1, which we evaluated in this study. We hypothesized that the common trigger for these pathways is the APOL1 cation channel, which is …

Measurement Matters: Higher Waist-To-Hip Ratio But Not Body Mass Index Is Associated With Deficits In Executive Functions And Episodic Memory, Andree Hartanto, Jose C. Yong

Research Collection School of Social Sciences

Background: The current study aimed to reconcile the inconsistent findings between obesity, executive functions, and episodic memory by addressing major limitations of previous studies, including overreliance on body mass index (BMI), small sample sizes, and failure to control for confounds. Methods: Participants consisted of 3,712 midlife adults from the Cognitive Project of the National Survey of Midlife Development. Executive functions and episodic memory were measured by a battery of cognitive function tests. Results: We found that higher waist-to-hip ratio was associated with deficits in both executive functions and episodic memory, above and beyond the influence of demographics, comorbid health issues, …

Jailangkung: Indonesian Spirit-Basket Divination, Margaret Chan

Research Collection School of Social Sciences

Chinese spirit-basket divination, which dates to the fifth century, would have been lost to the world had it not been reincarnated as Indonesian jailangkung. The term is the homophonic rendition of the Chinese cai lan gong [菜篮公, vegetable basket deity] and unambiguously links the Indonesian practice with the Chinese. Contemporary Chinese divinatory methods have replaced the clumsy basket planchette with the handier tri-forked branch or a pen held in the medium’s hand, but a spirit-basket still features in jailangkung and remains the key element in involutions of the prototype. For example, Nini Thowong’s spirit-possessed doll, is essentially an anthropomorphic effigy …

A Hybrid Model For Identity Obfuscation By Face Replacement, Qianru Sun, Ayush Tewari, Weipeng Xu, Mario Fritz, Christian Theobalt, Bernt Schiele

Research Collection School Of Computing and Information Systems

As more and more personal photos are shared and tagged in social media, avoiding privacy risks such as unintended recognition, becomes increasingly challenging. We propose a new hybrid approach to obfuscate identities in photos by head replacement. Our approach combines state of the art parametric face synthesis with latest advances in Generative Adversarial Networks (GAN) for data-driven image synthesis. On the one hand, the parametric part of our method gives us control over the facial parameters and allows for explicit manipulation of the identity. On the other hand, the data-driven aspects allow for adding fine details and overall realism as …

Challenges In Learning Uml: From The Perspective Of Diagrammatic Representation And Reasoning, Z. Shen, S. Tan, Keng Siau

Research Collection School Of Computing and Information Systems

Unified modeling language (UML) is widely taught in the information systems (IS) curriculum. To understand UML in IS education, this paper reports on an empirical study that taps into students’ learning of UML. The study uses a concept-mapping technique to identify the challenges in learning UML notational elements. It reveals that some technical properties of UML diagrammatic representation, coupled with students’ cognitive attributes, hinder both perceptual and conceptual processes involved in searching, recognizing, and inferring visual information, which creates learning barriers. This paper also discusses how to facilitate perceptual and conceptual processes in instruction to overcome learning challenges. The study …

Urban Food Entrepreneurship, Governance, And Economic Development In The Post-Industrial Cities Of Newark, New Jersey And Dayton, Ohio, John C. Jones

Dissertations

The local governments of post-industrial cities in the US struggle to foster economic development and to find uses for underutilized or abandoned urban land and buildings. Partly in response to growing consumer interest in locally produced foods, food entrepreneurs are increasingly using these underutilized urban properties for farming or for producing value-added food products. However, sometimes intentionally and sometimes unintentionally, existing policies and regulatory regimes of local and state governments often restrict the ability of urban food entrepreneurs to grow. This dissertation documents urban food entrepreneurship in the post-industrial communities of greater Newark, New Jersey and greater Dayton, Ohio. The …

Temporal And Spatial Effects Of Shock Overpressure On Blood-Brain Barrier Permeability In Blast-Induced Traumatic Brain Injury, Matthew Joseph Kuriakose

Dissertations

Exposure to shock waves is the leading cause of traumatic brain injury (TBI) in military personnel and blast-induced TBI (bTBI) is considered the signature wound in recent conflicts in Iraq and Afghanistan. Many researchers attempt to replicate field-relevant shock waves in laboratory settings through the use of gas-driven shock tubes in order to investigate the generation and propagation of shock waves and also explore possible mechanisms of bTBI. Among several injury mechanisms of bTBI, damage to the blood-brain barrier (BBB) has been identified as a potential candidate and has been the focus of several clinical and experimental investigations aimed to …

16-04 Effectiveness Of Bicycle Signals For Improving Safety And Multimodal Mobility At Urban Intersections, Jun-Seok Oh, Valerian Kwigizile, Odai Al Houz

Transportation Research Center Reports

With the dramatic increase of non-motorized transportation users, more people are concerned about the non-motorized traffic safety. Unfortunately, bicyclists and pedestrians are prone to more severe injuries when involved in a crash. For bicycle crashes, failing to yield/disregarding traffic control device, and lack of non-motorized facilities were identified to be the main causes of bicycle crashes in urban intersections. This research investigated the effectiveness of two bicycle crash countermeasures with bicycle signal treatments at urban signalized intersections. These two countermeasures are the bike boxes and the protected intersections. The bicycle signal treatments that were tested simultaneously with these countermeasures are …

The Effects Of Density Gradients On The Distribution And Behavior Of Copepods, Connor Cayson

Theses

Observations of fine-scale behavioral dynamics of zooplankton may shed insight into much larger-scale ecosystem patterns and phenomena. Some zooplankton, such as copepods, are known to aggregate near density gradients; however, it is not clear the extent to which density gradients alone affect copepod distribution and behavior, since these gradients are often associated with phytoplankton layers. In this study, we investigated the behavior of Calanus pacificus in response to salinity gradients through laboratory experiments observed with high-resolution video and analyzed using computational techniques. Image data were collected using two cameras recording continuously for a duration of 30 minutes or more, allowing …

Effects Of Fruit Position In Standard Place Pack Cartons And Gamma 1 Irradiation On The Postharvest Quality Of ‘Barnfield’ Navel Oranges, Karina Cruz Rodriguez (Friscia), José De Jesús Ornelas-Paz, Vrani Ibarra-Junquera, Maria Criselda Toto, Akanksha Jain, Anuradha Prakash

Food Science Faculty Articles and Research

The objective of this study was to determine if oranges in the top and bottom layers within a Standard Place Pack were impacted differently by irradiation after long-term storage. ‘Barnfield’ Navel oranges were packed in Standard Place Pack cartons and treated with 0, 0.15, or 1 kGy of gamma irradiation. The fruit were stored for 3 weeks at 5 °C and then for 1 week at 20 °C. After storage, the fruit from the top and bottom layers were separately evaluated for quality. The development of stem-end rind breakdown (SERB) was the main cause of quality loss and was greater …
