Determination Of Pathogenicity Of Breast Cancer 1 Gene Variants Using The American College Of Medical Genetics And Genomics And The Association For Molecular Pathology Guidelines, Angela Brown, Mansour Zamanpoor, Donald R. Prosser, Debra O.

Sultan Qaboos University Medical Journal

Objectives: Molecular diagnostic laboratories screen for mutations in disease-causing genes in order to confirm a clinical diagnosis. The classification of DNA variants as ‘pathogenic’ or ‘likely pathogenic’ mutations creates a workflow bottleneck, which becomes increasingly challenging as greater number of genes are screened. The classification challenge is also acute if there are conflicting reports regarding pathogenicity and differing classification criteria between laboratories. This study aimed to compare two procedures for the classification of variants in the breast cancer (BRCA)1 gene. Methods: This bioinformatic study was conducted at LabPLUS, Auckland, New Zealand, from February to June 2017. DNA was extracted from …

Does Corporate Social Responsibility Reduce The Costs Of High Leverage? Evidence From Capital Structure And Product Market Interactions, Kee-Hong Bae, Sadok El Ghoul, Omrane Guedhami, Chuck C.Y. Kwok, Ying Zheng

Finance Department Faculty Journal Articles

Research on capital structure and product market interactions shows that high leverage is associated with substantial losses in market share due to unfavorable actions by customers and competitors. We examine whether corporate social responsibility (CSR) affects firms’ interactions with customers and competitors, and whether it can reduce the costs of high leverage. We find that CSR reduces losses in market share when firms are highly leveraged. By reducing adverse behavior by customers and competitors, CSR helps highly leveraged firms keep customers and guard against rivals’ predation. Our results support the stakeholder value maximization view of CSR.

Twitter Use By Academic Libraries In New York State, Sheena Philogene

Urban Library Journal

Twitter can be a productive tool for academic libraries to use when sharing information, marketing services, and building relationships with students, yet it is difficult to know whether academic libraries are utilizing this platform by creating an independent library account. Furthermore, if academic libraries do have accounts, it is valuable to understand what academic libraries use Twitter for, and what kinds of media they share. The purpose of this study then is to investigate whether academic libraries in New York State (NYS) use Twitter, and if they do, how and why. Based on a sample of 226 academic libraries of …

Effects Of Two Intake Levels Of Leucaena Leucocephala On Rumen Function Of Sheep, Marcos Barros-Rodríguez, Javier Solorio-Sánchez, Carlos Sandoval-Castro, Athol V. Klieve, Eduardo Briceño-Poot, Luis Ramírez-Avilés, Rafael Rojas-Herrera

IGC Proceedings (1977-2023)

Ruminant production systems based on grass pastures often produce poor animal performance as expressed by growth or reproductive rates. The nutrient imbalance affecting rumen function is due to their low energy and protein intake. The incorporation of leguminous forages such as Leucaena leucocephala, in the diet of ruminants, can stimulate rumen function by providing protein-rich forage (Barros-Rodriguez et al. 2012). This increases the availability of compounds such as ammonia, amino acids and peptides as well as branched short-chain fatty acids, which are produced as a result of degradation of proteins. These substances promote fibre breakdown by acting as ruminal …

Conceptual Image Of English, Russian And Uzbek Socio-Political Discourse (Comparison), Gulnoza Amonova Phd Student

Philology Matters

The thesaurus of socio-political vocabulary is based on intra-systemic conceptual relations between units of this lexical group. The concept “power” is a structure-formed mean for this vocabulary. Being the main descriptors of the thesaurus of socio-political vocabulary, concepts project a number of their characteristics on to the lexical groups organized by them. Moreover, the structure of the corresponding branches of the thesaurus is largely determined by the internal, structural features of the concepts. As a result of this, it seems necessary to analyze these key concepts for socio-political vocabulary, as well as the concepts “people” and “nation” that are significant …

Peroxiredoxin 6 And Inflammation In Alzheimer's Disease, Jared Ferrell-Penniman

Biological Sciences Theses and Dissertations

Alzheimer’s disease (AD) is known for its debilitating symptoms and poor prognosis. However, despite intense research into neurodegenerative diseases, there are few therapies targeted at the underlying mechanisms of the disease. Oxidative stress (OS) and inflammation are cellular phenomena thought to be key to the progression of the disease. Critically, peroxiredoxin 6 (Prx6), an antioxidant protein with multiple functions, has been identified from mammalian studies as a potential regulator of both OS and inflammation that may have a specific effect on AD. This project seeks to elucidate the role of Prx6 in AD as well as the underlying mechanisms. Drosophila …

Bridging Between Protein Dynamics And Evolution Through Simulations And Machine Learning Approaches, Feng Wang

Chemistry Theses and Dissertations

Antibiotics resistance posed a serious threat to the public health and caused huge economic cost. β-Lactamases, which are enzymes produced by bacteria to hydrolyze β-lactam based antibiotics, are one of the driving forces behind antibiotic resistance. To explore the antibiotic resistance effect, understanding the mechanistic and dynamical features of β-lactamases through their interactions with antibiotics is critical. In my doctoral research, I applied both molecular dynamic (MD) simulations and machine learning approaches to explore these crucial interactions. Vancomycin is a typical glycopeptide antibiotic, which inhibits the bacterial cell wall through binding with peptidoglycan (PG). The key interactions of vancomycin and …

Mindfulness Within Relationships: Is Partner Discrepancy Related To Relationship Satisfaction, Chelsea Carson

Psychology Theses and Dissertations

Mindfulness has been linked with positive relationship outcomes; however, there is limited understanding regarding which facets of mindfulness are most related to couples’ relationship satisfaction and the potential role of discrepancy in mindfulness between partners for relationship satisfaction. Additionally, previous studies did not account for individuals’ well-being, a potential confounding variable in the association between mindfulness and relationship satisfaction. The present study examined the relation between each facet of mindfulness using the Five Facets of Mindfulness Questionnaire and relationship satisfaction (Couple Satisfaction Inventory), while controlling for well-being (Compass Assessment System) using Actor Partner Interdependence Models. The relation between discrepancies in …

Stochastic Orthogonalization And Its Application To Machine Learning, Yu Hong

Electrical Engineering Theses and Dissertations

Orthogonal transformations have driven many great achievements in signal processing. They simplify computation and stabilize convergence during parameter training. Researchers have introduced orthogonality to machine learning recently and have obtained some encouraging results. In this thesis, three new orthogonal constraint algorithms based on a stochastic version of an SVD-based cost are proposed, which are suited to training large-scale matrices in convolutional neural networks. We have observed better performance in comparison with other orthogonal algorithms for convolutional neural networks.

“Spirited” Engagement: Latin American Faith And The Construction Of Emancipative Pentecostalism, David Luckey

Religious Studies Theses and Dissertations

Pentecostalism is a prominent form of Christianity around the world that is increasingly pervasive in the Global South. One of the persistent issues that obscures accurate understanding of the movement is the question of whether such a spiritually-oriented faith gives attention to social realities. This dissertation identifies a broad spectrum of Latin America Pentecostal social- ethical engagement in order to complicate stereotypes and reveal a natural orientation toward public witness. It shows that Pentecostalism is too complex for broad generalization, and it draws on leading voices from within the movement to articulate a call to increasing efforts for social justice.

Sample Size Considerations For Clustered And Correlated Outcomes In Clinical Research, Xiaohan Xu

Statistical Science Theses and Dissertations

In this dissertation, we investigate sample size calculations for three different study designs: stratified cluster randomization trials (CRTs), paired experimental designs and paired cluster experimental designs.

Stratified CRTs have been frequently employed in clinical and healthcare research. Comparing with simple randomized CRTs, stratified CRTs reduce the imbalance of baseline prognostic factors among different intervention groups. Clusters are often naturally formed with random sizes in CRTs. With varying cluster size, commonly used ad hoc approaches ignore the variability in cluster size, which may underestimate (overestimate) the required number of clusters for each group per stratum and lead to underpowered (overpowered) clinical …

For safe and effective use, it is imperative to not only measure the initial physicochemical and structural properties of nanomaterials, but also identify and quantify any property changes related to a loss of chemical and/or physical integrity during processing and usage conditions. In this study an assessment of iron oxide magnetic nanoparticle thermal stability using modulated differential scanning calorimetry (mDSC) and a controlled-heating system is conducted …

The Unmarried (M)Other: A Study Of Christianity, Capitalism, And Counternarratives Concerning Motherhood And Marriage In The United States And South Africa, Haley Feuerbacher

Religious Studies Theses and Dissertations

A reified and patriarchal form of Christianity that emphasizes “family values” – that is, adherence to the formula of a male-headed, heterosexual, capitalist, nuclear family, characterized by distinct, complementary, and hierarchical gender roles as essential to the well-being of individuals, one’s nation, and the ecumenical Church - over “community values” has become a happy bedfellow of the market system and neocolonialism, extending its reach worldwide through globalization. The result is that single mothers constitute the most economically oppressed demographic internationally across all race and ethnic categories. Using Constructivist Grounded Theory and a postcolonial feminist theological lens to collect, retell, and …

Being Here And Now: The Benefits Of Belonging In Space And Time, Matthew Baldwin, Lucas A. Keefer

Faculty Publications

Research suggests that a sense of belonging is a critical prerequisite of happiness and well-being. While some have focused on belonging provided by relationships, other work demonstrates the value of belonging in certain places. In the current research we join these efforts to understand belonging by offering a novel framework for exploring an understudied but no less fundamental aspect of human experience—time. We situate this framework within an existential analysis of human action and test general predictions about the psychological value of experiencing a sense of belonging in time, what we call temporal rootedness. Two samples (Studies 1 …

Ethical Consistency And Experience: An Attempt To Influence Researcher Attitudes Toward Questionable Research Practices Through Reading Prompts, Samuel V. Bruton, Mitch Brown, Donald F. Sacco

Faculty Publications

Over the past couple of decades, the apparent widespread occurrence of Questionable Research Practices (QRPs) in scientific research has been widely discussed in the research ethics literature as a source of concern. Various ways of reducing their use have been proposed and implemented, ranging from improved training and incentives for adopting best practices to systematic reforms. This article reports on the results of two studies that investigated the efficacy of simple, psychological interventions aimed at changing researcher attitudes toward QRPs. While the interventions did not significantly modify researchers’ reactions to QRPs, they showed differential efficacy depending on scientists’ experience, suggesting …
