This study is split into two smaller projects that both aim to provide further insights on how to develop online activities that target undergraduate biology students. The first project revealed that elaborative feedback in a phylogenetic activity was more useful for students who had some exposure to phylogenetics prior to completing the activity. The results of the second project revealed that the appearance …

Development Of New Bioinformatic Approaches For Human Genetic Studies, Jose Andres Guevara Coto

All Dissertations

The development of bioinformatics methods for human genetic studies utilizes the vast amount of data to generate new valuable information. Machine learning and statistical coupling analysis can be used in the study of human diseases. These diseases include intellectual disabilities (ID), prevalent in 1-3% of the population and caused primarily by genetics. Although many cases of ID are caused by mutations in protein-coding genes, the possible involvement of long non-coding RNAs (lncRNAs) in ID due to their role in gene expression regulation, has been explored. In this study, we used machine learning to develop a new expression-based model trained using …

Breaking Invisibility: Transforming Working Conditions Of Adjunct Faculty In Technical Colleges Through Critical Advocacy Inquiry, Jacqueline Y. Taylor

All Dissertations

Known as "invisible faculty," (Gappa & Leslie, 1993), adjunct or part-time, contingent instructors play a vital role in meeting the needs of two-year colleges. Adjunct faculty members teach over half of the United States' historically underserved college students (Center for Community College Student Engagement [CCCSE], 2014), and are therefore vital to student and college success. Moreover, 58% of all South Carolinian undergraduates attend one of the 16 technical colleges in the South Carolina Technical College System (South Carolina Technical College System [SCTCS], 2016). Additionally, 60% of the faculty members in the SCTCS are adjunct instructors (SCTCS, 2017). Researchers claim adjunct …

Impacts Of Exposure To A High Concentrate Based Diet On Marbling Development In Beef Cattle, Brandon Michael Koch

All Dissertations

The value of a carcass is largely dependent on lipid deposition. The subcutaneous and visceral depots are often reported to develop and fill first. These depots also have little to no value, and often result in carcass price discounts. The intramuscular depot is well correlated with consumer palatability and carcass value. The ability to increase deposition of intramuscular lipid while minimizing the filling of low value fat depots provides ample opportunity to improve carcass value. Three studies were performed to investigate the ability to improve marbling deposition by altering the timing and duration of exposure to high concentrate diets. The …

Using App Inventor To Explore Low-Achieving Students' Understanding Of Fractions, Lorraine Ann Jacques

All Dissertations

A student's understanding of fraction magnitude impacts his/her understanding of algebra (e.g., Booth & Newton, 2012; Siegler et al., 2012), which then influences his/her likelihood of graduating high school (Orihuela, 2006) or succeeding in higher education (Adelman & United States., 2006; Trusty & Niles, 2004). Literature suggests that students gain this understanding when they create and work with various representations of fractions (e.g., Ainsworth, Bibby, & Wood, 2002; Panaoura et al., 2009; Siegler, Fazio, Bailey, & Zhou, 2013), which can occur when students engage in constructivist activities such as developing games (Kafai, 1996, Apr). This study examines an intervention where …

Understanding Intracellular Redox Regulation In Methanogens: Characterization Of The Components And Targets Of The Nadph-Dependent Thioredoxin System From Methanosarcina Acetivorans, Addison Clark Mccarver

Graduate Theses and Dissertations

All cells have a reduced intracellular environment. In the presence of oxygen, the non-specific oxidation of intracellular components leads to the production of reactive oxygen species (ROS) within cells leading to oxidative stress. During oxidative stress labile cofactors (e.g. Fe-S clusters) are lost and deleterious disulfide bonds are formed within proteins. Intracellular redox maintenance systems are used to direct reducing equivalents towards the repair of oxidatively-damaged proteins. The thioredoxin system is the ubiquitous intracellular redox system, found in virtually all species. The canonical thioredoxin system is comprised of a NADPH-dependent thioredoxin reductase (TrxR) that functions to reduced thioredoxin (Trx). Although …

On The Properties Of The Weibull-Burr Iii Distribution And Its Application To Uncensored And Censored Survival Data, Aliyu Yakubu, Sani I. Doguwa

CBN Journal of Applied Statistics (JAS)

Twelve different families of cumulative distributions that are used to model real life data were introduced by Burr (1942). Burr III distribution is among these families of cumulative distributions. In this work, a four-parameter distribution is introduced to model real life scenarios called Weibull-Burr III distribution. The limiting behavior of the proposed distribution, hazard function, moments, skewness, kurtosis and quantile function is investigated; order statistics and entropy are also derived. The method of Maximum Likelihood Estimation technique was used in estimating the parameters of the proposed distribution. To prove the flexibility and performance of the distribution and Weibull-G family of …

Predictor Of Diabetes: Correlation Between Leucine Concentration And Insulin Resistance, Chyntia R. Wijaya, Indriyanti R. Sukmana, Jutti Levita

Pharmacology and Clinical Pharmacy Research

Leucine catabolism changes among people with central obesity. This condition can lead to metabolic pathway disorder and increased mTORC-1 activation. Downstream signal of mTORC-1 is p70S6K1, which causes phosphorylation of insulin-1 receptor substrate (IRC-1). This study was performed to evaluate correlation between leucine concentration and insulin resistance (IR). This study was a prospective cross-sectional study, involving two groups; control and obese group. General characteristics and blood sample were taken from each subject. Leucin and Homeostasis Model Assesment (HOMA)-IR, as the marker of insulin resistance, were evaluated. The result indicated a significant positive correlation between leucine concentration and insulin resistance value …

Motives Of Corporate Political Donations: Industry Regulation, Subjective Judgement And The Origins Of Pragmatic And Ideological Corporations, Nicholas M. Harrigan

Research Collection School of Social Sciences

What motivates corporate political action? Are corporations motivated by their own narrow economic self-interest; are they committed to pursuing larger class interests; or are corporations instruments for status groups to pursue their own agendas? Sociologists have been divided over this question for much of the last century. This paper introduces a novel case - that of Australia - and an extensive dataset of over 1,500 corporations and 7,500 directors. The paper attempts to understand the motives of corporate political action by examining patterns of corporate political donations. Using statistical modelling, supported by qualitative evidence, the paper argues that, in the …

Kiasu And Creativity In Singapore: An Empirical Test Of The Situated Dynamics Framework, Chi-Ying Cheng, Ying-Yi Hong

Research Collection School of Social Sciences

This article investigates how Singaporeans' creativity is influenced by Kiasu, an indigenous construct corresponding to fear of losing out. We examine the impact of Kiasu on creativity, both as a personal value and a shared cultural norm in four studies. Study 1 showed that Singaporeans' Kiasu value endorsement predicts lower individual creativity. Study 2 demonstrated that this negative relationship is mediated by a self-regulatory focus on prevention. Study 3 further showed the impact of Kiasu as a personal value and a cultural norm by finding a significant three-way interaction effect of Kiasu prime, personal Kiasu value endorsement, and need for …

Asian Extremes: Experience And Exchange In The Development Of Meteorological Knowledge C. 1840-1930, Fiona Williamson, Clive Wilkinson

Numerical Cognition In Action: Hand Trajectories Reveal Effects Of Early Musical Training On Numerical Processing In Spanish-English Bilingual Musicians, Daniel Arturo Pizaña

Theses and Dissertations

The mouse-tracking study examined whether early musical experience leads to changes of inhibitory control in numerical processing for bilingual speakers, as has not investigated in previous studies. Twenty-eight Spanish-English bilingual students completed two Stroop-like numerical and physical size judgment tasks via a mouse-tracking paradigm. Results showed that response times were slower during both incongruent and neutral trials for bilinguals who had received early musical training (before age 13) when compared to bilinguals who had received late musical training (after age 13) across tasks. Furthermore, hand trajectories revealed that a spatial attraction toward the incorrect response was more pronounced in bilinguals …
