Physical Activity Among Preschool-Aged Children: Considerations For Waking Activity Patterns And Health, Erin Dooley

Dissertations and Theses (Open Access)

With nearly one-quarter (23%) of U.S. preschool children (ages 3-5 years) having overweight or obesity, supporting healthy growth and development is paramount. Hispanic children have the highest prevalence within this age group (15.6%) and a large projected population growth. Energy expenditure through physical activity is one way to combat excess development of obesity and poor health outcomes. Yet there is limited evidence about the correlates associated with physical activity and health within this population. The three studies of this dissertation examined sociodemographic-, cultural-, and context-related factors related to waking activity patterns and the subsequent impact on health indicators. The overall …

Quantifying The Financial & Clinical Impact Of Annual Vs. Biennial Mammography Screening, Danmeng Huang

Dissertations and Theses (Open Access)

Current guidelines for screening mammography recommend different start ages and intervals for women with average cancer risk. Longer intervals between mammograms allow more time for a tumor to grow, to become symptomatic and clinically detectable, and more likely to be at advanced stage. Existing literature on the associations between mammography screening frequency and risk of more advanced breast cancer have mixed results. Studies have showed that advanced breast cancer costs more to treat, but real-world cost estimates following different mammography screening frequencies are unavailable. To fill the gaps, this dissertation aimed to quantify the clinical and financial impact following annual …

Epidemiological Evaluation Of The National Sickle Cell Screening Program In The Republic Of Uganda, Arielle G. Hernandez

Dissertations and Theses (Open Access)

Sickle cell anemia contributes substantially to childhood morbidity and mortality in sub-Saharan Africa, where there are scarce health resources and inadequate awareness among healthcare providers and the community. Without early diagnosis and initiation of preventive treatments, most infants will die of acute complications before their fifth birthday. Information on the mortality associated with sickle cell anemia is excluded from global statistical summaries due to the lack of accurate data, making sickle cell anemia an invisible killer of children on the African continent. Information from long-term large-scale sickle cell screening efforts is not yet available in Africa; therefore, a mixed-methods study …

The Associations Between Fat And Clinical Outcomes Among Lung Cancer Patients: Dietary Intake And Genetic Determinants, Fang Yu Lin

Dissertations and Theses (Open Access)

Higher dietary fat intake and alterations in fatty acid metabolism may affect cancer development and progression.

Nonlinear Functional Models On Causal Inference, Rong Jiao

Dissertations and Theses (Open Access)

Statistical analysis has experienced significant progress on association study, but it remains elusive to understand the etiology and mechanism of complex phenotypes. As a major analytical platform, association analysis may hamper the theoretic development of biomedical science and its application. Thus, many researchers suggest making the transition from association to causation. The mainstream of research in genetics and epigenetics data analysis focuses on statistical association or exploring statistical dependence between variables. Despite significant progress in dissecting the genetic architecture of complex diseases by genome-wide association studies (GWAS), the signals identified by association analysis can only explain a small proportion of …

Optical Spectrsocopy Of Murine Breast Tumor To Distinguish Indolent From Aggressive Disease, Joel Rodriguez Troncoso

Biomedical Engineering Undergraduate Honors Theses

Breast cancer accounts for 30% of all cancer. Metastasis is the primary cause of death among breast cancer patients. Additionally, current molecular profiling methods such as Oncotype DX, which are expensive and not widely available at all clinical facilities, only determine the risk of recurrence after treatment. Therefore, there are no current method capable of identifying metastatic patients in advance.As a result, there is an unmet clinical need to develop a cost-effective prognostic to differentiate between indolent and aggressive breast tumors. In this study, we implemented diffuse reflectance spectroscopy (DRS) system to evaluate functional changes in tumor xenografts originated from …

The Monkey Queen: Creating Cultural Connections Through Theatre For Young Audiences, Matt Loehrke

Master's Theses

Youth in America have access to numerous stories on stage, page, and screen, yet many of those tales originate from white, Euro-centric cultures. Current trends in American theatre often produce familiar scripts to present to their communities. Unfortunately, too often, stories from other cultures are not adapted and presented. This thesis seeks to provide a culture bridge by adapting one of China’s most beloved stories, The Monkey King, for a young American audience through the medium of Theatre for Young Audiences. Theatre is a great unifier; however, the most critical audience, the audience that will grow into the next generation …

Chromium Mediated Oxidative Transposition Of Secondary Benzylic Alcohols, Samara Weber

Master's Theses

Carbonyl transposition serves as an important reaction in organic synthesis. Carbonyl transposition results in transposition of the functional groups without loss of the carbonyl moiety. Chromium oxidations of tertiary unsaturated carbinols have been studied since the 1970’s for their ability to cause carbonyl transposition. It is only recently that carbonyl transposition of secondary unsaturated benzylic alcohols has been reported with the use of chromium. Different oxidation reactions were examined for the potential carbonyl transposition products. Oxidation of unsaturated benzylic alcohols were maintained at varying temperature with pyridinium chlorochromate to monitor for the formation of product. As the temperature increased an …

According to Liu et al. (2019), Liutex has been proposed as a new physical quantity with scalar, vector and tensor forms. A Liutex vector is defined as a rotation part of fluid motion without shear contamination. The …

Mathematical Modeling Of A Network Of Neurons Regarding Glucose Transport Deficiency Induced Epileptic Seizures, Ariel N. Leslie

Mathematics Dissertations - Archive

Epilepsy is a complex phenomena of a system of neurons simultaneously firing that are highly intensive and synchronized. Seizures are a common and well known physical feature for all types of epileptic disorders [8]. Epilepsy is known to be traced back to spatial and temporal patterns working in sequence. The rhythms, patterns, and oscillatory dynamics explain the mechanistic nature of neurons especially in absence seizures [37]. An electroencephalogram device (EEG) monitors the electrical activity within the brain using small electrodes, which measures voltage fluctuations on the scalp. Previous models such as Wilson-Cowan (1972) [34], introduced a model showing the dynamics …

Case Study Analysis Of Shared Visual Arguments And Propaganda Techniques Of Russian Propaganda Posters And Russian Internet Memes, Cindy D. Vasquez

Communication Theses - Archive

Rhetoric, the study of argument using logic, has been studied for centuries. However, there is some disagreement among scholars on whether or not argumentation can be applied to visual imagery. Images are noted to have more emotional appeal than text does. Visual propaganda was mass produced in the form of propaganda posters, most popularly in the early 20th century. In more recent times, the sharing of images has moved to social media, popularly through memes. This paper analyzes two Soviet propaganda posters produced by one Soviet publishing house, Litizdat, and two memes created by the Russian organization the Internet Research …

Reorganizations, Sales, And The Changing Face Of Restructuring In Canada: Quantitative Outcomes Of 2012 And 2013 Ccaa Proceedings, Alfonso Nocilla

Dalhousie Law Journal

This article examines quantitative data on the outcomes of proceedings under the Companies’ Creditors Arrangement Act (CCAA), Canada’s principal statute for resolving large, complex corporate insolvencies. In particular, this article compares the durations, direct costs, and returns to different classes of creditors generated by traditional reorganizations under the CCAA and by “liquidating CCAAs”—that is, proceedings in which the insolvent debtor sells substantially all of its assets rather than reorganizing itself. The article makes a number of contributions to the existing scholarship. Firstly, quantitative data on CCAA proceedings are rare. The data examined here, collected by the author from proceedings initiated …
