Indigenous Knowledge Of Rift Valley Fever Among Somali Nomadic Pastoralists And Its Implications On Public Health Delivery Approaches In Ijara Sub-County, North Eastern Kenya, Geoffrey Otieno Muga, Washington Onyango-Ouma, Rosemary Sang, Hippolyte Affognon

All Peer-Reviewed Publications

Rift Valley Fever (RVF) is a zoonotic disease whose outbreak results in heavy economic and public health burdens. In East Africa, RVF is mainly experienced in arid and semi-arid areas predominantly inhabited by the pastoralists. These areas experience sudden, dra-matic epidemics of the disease at intervals of approximately 10 years, associated with widespread flooding and the resultant swarms of mosquitoes. Pastoralists’ indigenous knowledge and experience of RVF is critical for public health interventions targeting prevention and control of RVF. The study adopted a descriptive cross-sectional design combining both quantitative and qualitative methods of data collection. A total of 204 respondents …

Afrotropical Sand Fly-Host Plant Relationships In A Leishmaniasis Endemic Area, Kenya, Iman B. Hassaballa, Catherine L. Sole, Xavier Cheseto, Baldwyn Torto, David P. Tchouassi

All Peer-Reviewed Publications

The bioecology of phlebotomine sand flies is intimately linked to the utilization of environmental resources including plant feeding. However, plant feeding behavior of sand flies remains largely understudied for Afrotropical species. Here, using a combination of bio-chemical, molecular, and chemical approaches, we decipher specific plant-feeding associa-tions in field-collected sand flies from a dry ecology endemic for leishmaniasis in Kenya. Cold-anthrone test indicative of recent plant feeding showed that fructose positivity rates were similar in both sand fly sexes and between those sampled indoors and outdoors. Analysis of derived sequences of the ribulose-1,5-bisphosphate carboxylase large subunit gene (rbcL) from fructose-positive specimens …

Plasmonic Waveguides To Enhance Quantum Electrodynamic Phenomena At The Nanoscale, Ying Li, Christos Argyropoulos

Department of Electrical and Computer Engineering: Faculty Publications

The emerging field of plasmonics can lead to enhanced light-matter interactions at extremely nanoscale regions. Plasmonic (metallic) devices promise to efficiently control both classical and quantum properties of light. Plasmonic waveguides are usually used to excite confined electromagnetic modes at the nanoscale that can strongly interact with matter. The analysis of these nanowaveguides exhibits similarities with their low frequency microwave counterparts. In this article, we review ways to study plasmonic nanostructures coupled to quantum optical emitters from a classical electromagnetic perspective. These quantum emitters are mainly used to generate single-photon quantum light that can be employed as a quantum bit …

Anisotropic Dielectric Functions, Band-To-Band Transitions, And Critical Points In Α-Ga2O3, Matthew J. Hilfiker, Rafal Korlacki, Riena Jinno, Yongjin Cho, Huili Grace Xing, Debdeep Jena, Ufuk Kilic, Megan Stokey, Mathias Schubert

Department of Electrical and Computer Engineering: Faculty Publications

We use a combined generalized spectroscopic ellipsometry and density functional theory approach to determine and analyze the anisotropic dielectric functions of an α-Ga₂O₃ thin film. The sample is grown epitaxially by plasma-assisted molecular beam epitaxy on m-plane sapphire. Generalized spectroscopic ellipsometry data from multiple sample azimuths in the spectral range from 0.73 eV to 8.75 eV are simultaneously analyzed. Density functional theory is used to calculate the valence and conduction band structure. We identify, for the indirect-bandgap material, two direct band-to-band transitions with M₀-type van Hove singularities for polarization perpendicular to the c axis, …

Hippocampal Subfield Volumetry From Structural Isotropic 1 Mm3 Mri Scans: A Note Of Caution, Laura E.M. Wisse, Gaël Chételat, Ana M. Daugherty, Robin De Flores, Renaud La Joie, Susanne G. Mueller, Craig E.L. Stark, Lei Wang, Paul A. Yushkevich, David Berron, Naftali Raz, Arnold Bakker, Rosanna K. Olsen, Valerie A. Carr

Faculty Research, Scholarly, and Creative Activity

Spurred by availability of automatic segmentation software, in vivo MRI investigations of human hippocampal subfield volumes have proliferated in the recent years. However, a majority of these studies apply automatic segmentation to MRI scans with approximately 1 × 1 × 1 mm3 resolution, a resolution at which the internal structure of the hippocampus can rarely be visualized. Many of these studies have reported contradictory and often neurobiologically surprising results pertaining to the involvement of hippocampal subfields in normal brain function, aging, and disease. In this commentary, we first outline our concerns regarding the utility and validity of subfield segmentation on …

Anti-Nlrp3 Inflammasome Natural Compounds: An Update, Baolong Liu, Jiujiu Yu

Department of Nutrition and Health Sciences: Faculty Publications

The nucleotide-binding domain and leucine-rich repeat related (NLR) family, pyrin domain containing 3 (NLRP3) inflammasome is a multimeric protein complex that recognizes various danger or stress signals from pathogens, the host, and the environment, leading to activation of caspase-1 and inducing inflammatory responses. This pro-inflammatory protein complex plays critical roles in pathogenesis of a wide range of diseases including neurodegenerative diseases, autoinflammatory diseases, and metabolic disorders. Therefore, intensive efforts have been devoted to understanding its activation mechanisms and to searching for its specific inhibitors. Approximately forty natural compounds with anti-NLRP3 inflammasome properties have been identified. Here, we provide an update …

Assessing The Predictors Of On-Campus Student Wellbeing In The Time Of Covid-19, Victoria Lynn Hrzich

Theses and Dissertations

College students endure a great deal of stress and are one of the most vulnerable groups for mental health difficulties. Despite the stressors they face, a vast array of research highlights several factors that contribute to student wellbeing, such as social support, coping, and psychological flexibility. Similar trends have been found in the literature on student distress and wellbeing following large-scale crises. Due to the unprecedented nature of COVID-19, there is limited research on student distress levels during the pandemic and the effectiveness of these previously useful stress management factors during this unique crisis. Therefore, the current study assessed student …

Development And Validation Of A Dft-Based Force Field For A Hydrated Homoalanine Polypeptide, Ying Yuan, Zhonghua Ma, Feng Wang

Chemistry & Biochemistry Faculty Publications and Presentations

A new force field has been created for simulating hydrated alanine polypeptides using the adaptive force matching (AFM) method. Only density functional theory calculations using the Perdew–Burke–Ernzerhof exchange–correlation functional and the D3 dispersion correction were used to fit the force field. The new force field, AFM2020, predicts NMR scalar coupling constants for hydrated homopolymeric alanine in better agreements with experimental data than several other models including those fitted directly to such data. For Ala₇, the new force field shows about 15% helical conformations, 20% conformation in the β basin, and 65% polyproline II. The predicted helical population of …

The Multifunctional Roles Of Polyphenols In Plant-Herbivore Interactions, Sukhman Singh, Ishveen Kaur, Rupesh R. Kariyat

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

There is no argument to the fact that insect herbivores cause significant losses to plant productivity in both natural and agricultural ecosystems. To counter this continuous onslaught, plants have evolved a suite of direct and indirect, constitutive and induced, chemical and physical defenses, and secondary metabolites are a key group that facilitates these defenses. Polyphenols—widely distributed in flowering plants—are the major group of such biologically active secondary metabolites. Recent advances in analytical chemistry and metabolomics have provided an opportunity to dig deep into extraction and quantification of plant-based natural products with insecticidal/insect deterrent activity, a potential sustainable pest management strategy. …

Using Yeast Two-Hybrid System And Molecular Dynamics Simulation To Detect Venom Protein-Protein Interactions, Ying Jia, Paulina Kowalski, Ivan Lopez

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Proteins and peptides are major components of snake venom. Venom protein transcriptomes and proteomes of many snake species have been reported; however, snake venom complexity (i.e., the venom protein-protein interactions, PPIs) remains largely unknown. To detect the venom protein interactions, we used the most common snake venom component, phospholipase A2s (PLA2s) as a “bait” to identify the interactions between PLA2s and 14 of the most common proteins in Western diamondback rattlesnake (Crotalus atrox) venom by using yeast two-hybrid (Y2H) analysis, a technique used to detect PPIs. As a result, we identified PLA2s interacting with themselves, and lysing-49 PLA2 …

Prevalence Of Cyberbullying Among Traditional Undergraduate Students Attending Faith-Based Universities: A Causal-Comparative Study, Susan Alice Hayes-Mcelroy

Doctoral Dissertations and Projects

Cyberbullying among traditional undergraduate students is a relatively new issue that involves the safety of postsecondary students. The purpose of this study was to provide statistical data to faith-based universities that relate the prevalence of cyberbullying victimization experiences and the prevalence of cyberbullying offending experiences of traditional undergraduate students to biological gender (female/male) and level of religiosity (higher/lower), and to add to the small body of research conducted among this demographic. In this quantitative, causal-comparative study, traditional undergraduate students were recruited from two faith-based universities in the southern United States. Level of religiosity and cyberbullying prevalence were determined through responses …

Understanding And Equipping Female Leadership At Prosperous Temple Church Of God In Christ, Jonathan R. Hackett

Doctoral Dissertations and Projects

Debates on whether women qualify to take up church leadership have persisted over the years. In 2016, there was an instance in Alabama where a woman was appointed as the assistant pastor of a church. Within three months of her service, the number of congregants dropped. Efforts by the church management to unravel the cause of the decline revealed that a majority of the people, particularly women, who canceled their church attendance were uncomfortable with women taking up leadership positions. The case informed this research, which will use the case study of Prosperous Temple Church of God in Christ. The …

Open Access Publications

It is unclear if surveillance for postmenopausal women with medically inoperable stage 1 endometrial cancer (EC) should differ depending on their management strategy. Thus, we investigated the utility of surveillance endometrial sampling among 53 postmenopausal women with medically inoperable, clinical stage I, grade 1 endometrioid EC who received either progestin therapy or radiation between 2009 and 2018, at a single academic institution. Frequency and results of endometrial sampling, as well as recurrence and survival rates were studied. Of 53 patients, 18 (34.0%) received progestin therapy and 35 (66.0%) radiation. Medically managed patients were treated with megestrol acetate (27.7%), a levonorgestrel …

Lynch, Fernández-Llamazares Álvaro, Ignacio Palomo, Pedro Jaureguiberry, Amano Tatsuya, Zeenatul Basher, Michelle Lim, Tuyeni Heita Mwampamba, Aibek Samakov, Odirilwe Selomane, Michelle Mei Ling Lim

Research Collection Yong Pung How School Of Law

Multicultural representation is a stated goal of many global scientific assessment processes. These processes aim to mobilize a broader, more diverse knowledge base and increase legitimacy and inclusiveness of these assessment processes. Often, enhancing cultural diversity is encouraged through involvement of diverse expert teams and sources of knowledge in different languages. In this article, we examine linguistic diversity, as one representation of cultural diversity, in the eight published assessments of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES). Our results show that the IPBES assessment outputs are disproportionately filtered through English-language literature and authors from Anglophone countries. To …

Mapping Seagrass Habitat And Characterising Dugong Feeding Preferences In Sibu-Tinggi Archipelago, Johor, Heng Wei Khang

Student Works (2020-2029)

The dugong (Dugong dugon) is a marine mega-herbivore that is a seagrass community specialist. Seagrass meadows are eminently essential to dugongs as their main feeding grounds. The species’ feeding behavioural patterns are often associated with the features of the seagrass habitat. Elucidating such behavioural patterns is vital for understanding how a designated space is used. In Malaysia, the Sibu-Tinggi Archipelago, is regarded as one of the most important habitats for dugongs, hosting a significant local population due to the presence of extensive subtidal seagrass meadows. Field surveys were conducted in 2016 – 2018, across three seasons influenced by the northeast …

Learning To Pre-Train Graph Neural Networks, Yuanfu Lu, Xunqiang Jiang, Yuan Fang, Chuan Shi

Research Collection School Of Computing and Information Systems

Graph neural networks (GNNs) have become the de facto standard for representation learning on graphs, which derive effective node representations by recursively aggregating information from graph neighborhoods. While GNNs can be trained from scratch, pre-training GNNs to learn transferable knowledge for downstream tasks has recently been demonstrated to improve the state of the art. However, conventional GNN pre-training methods follow a two-step paradigm: 1) pre-training on abundant unlabeled data and 2) fine-tuning on downstream labeled data, between which there exists a significant gap due to the divergence of optimization objectives in the two steps. In this paper, we conduct an …

The Meaning Of “Phenomenology”: Qualitative And Philosophical Phenomenological Research Methods, Heath Williams

The Qualitative Report

I show some problems with recent discussions within qualitative research that centre around the “authenticity” of phenomenological research methods. I argue that attempts to restrict the scope of the term “phenomenology” via reference to the phenomenological philosophy of Husserl are misguided, because the meaning of the term “phenomenology” is only broadly restricted by etymology. My argument has two prongs: first, via a discussion of Husserl, I show that the canonical phenomenological tradition gives rise to many traits of contemporary qualitative phenomenological theory that are purportedly insufficiently genuine (such as characterisations of phenomenology as “what-its-likeness” and presuppositionless description). Second, I argue …
