A Meta-Analysis Of Graphic Organizer Reading Interventions For Learning Science And Social Studies Content, Ashley Sandoval

Teaching and Learning Theses and Dissertations

In this meta-analysis, the effects of text-based graphic organizer interventions on content learning in Science and Social Studies for students in grades 3-12, including typically developing and struggling students, and students with disabilities (i.e., LD, ID, and ASD) were assessed. A random-effects model with a correlated robust variance estimation approach was used and showed text based graphic organizer interventions had a large overall positive effect (ES = 1.65) on content learning in both Science and Social Studies. In addition, moderator analysis indicated that text-based graphic organizer interventions were more effective when students received teacher instruction prior to completing graphic …

The Limits Of The Ethnographic Turn, Bharat Ranganathan

Religion Faculty Publications

This article reflects on the ethnographic turn in recent comparative religious ethics (CRE). Comparative religious ethicists should be lauded because they privilege engagement with non-Western intellectual sources. Such engagement is important since it undermines the erroneous view that non-Western sources are either soft or are part of someone else's commitments and therefore irrelevant. Yet some recent comparative work stops at merely describing these non-Western sources, moving ethics away from its normative tasks. If CRE is to remain relevant to broader conversations in moral and political theory, comparative religious ethicists should perform two tasks: they should evaluate the object under consideration …

International Reverse Transfer Students: A Critical Analysis Based On Field, Habitus, And Social And Cultural Capital, Yu “April” Chen, Ran Li, Linda Serra Hagedorn

Faculty Publications

Objective: International reverse transfer students are international students who begin their postsecondary journey at a four-year institution but subsequently transfer to a community college. In this qualitative study, we examine the lived experiences of international reverse transfers to understand the reasons for reverse-transfer and to understand the students’ learning experiences. Methods: Using a phenomenological approach, we recruited 10 international reverse transfer students attending one four-year university or one of the two community colleges. We conducted individual interviews with all participants and analyzed transcript data through Bourdieu’s sociological theory of field, habitus, and social and cultural capital. Results: We identified three …

Leadership, Contexts, And Learning - Part 2. Theories Of Learning, Channels, And Curricula, Larry M. Starr, Phd

School of Continuing and Professional Studies Faculty Papers

In this second of a two-part essay (see Starr (2020a1) for part 1) a systems-informed discussion of learning leadership is presented. I review the components of a system which consist of inputs, transformation, outputs, feedback and contextual environment, and argue that from a system perspective learning leadership emerges from interactions among elements particularly contextual variables. The concept of context is expanded to include the theory of learning applied, i.e., pedagogy, andragogy or heutagogy, and the communication channel used, i.e., face-to-face, virtual/online, or hybrid/blended. Learning leadership is also influenced by environmental context variables such as threats to health and safety, financial …

A Two-Stage Machine Learning Framework To Predict Heart Transplantation Survival Probabilities Over Time With A Monotonic Probability Constraint, Hamidreza Ahady Dolatsaraa, Ying-Ju (Tessa) Chen, Christy Evans, Ashish Gupta, Fadel M. Megahed

Mathematics Faculty Publications

The overarching goal of this paper is to develop a modeling framework that can be used to obtain personalized, data-driven and monotonically constrained probability curves. This research is motivated by the important problem of improving the predictions for organ transplantation outcomes, which can inform updates made to organ allocation protocols, post-transplantation care pathways, and clinical resource utilization. In pursuit of our overarching goal and motivating problem, we propose a novel two-stage machine learning-based framework for obtaining monotonic probabilities over time. The first stage uses the standard approach of using independent machine learning models to predict transplantation outcomes for each time-period …

Does Christian Faith Impact Loneliness?, Jeffrey M. Kelly

Doctor of Psychology (PsyD)

Loneliness is on the rise within the United States, particularly within younger adults ages 18-37 (Bruce et al 2019). Although much is known about the negative dimensions of loneliness, and some about protective factors to help ease loneliness, the potential impact of religious and spiritual beliefs and behaviors on loneliness remains largely unexplored. This study focused on the relationship between a committed religious faith and perceived feelings of loneliness among university students. Participants include 1,182 undergraduate students from George Fox University who participated in the National College Health Assessment (NCHA). Religious commitment was evaluated using a supplemental 6-item self-report measure …

The Perfect Tree: The American Chestnut Tree In American Culture, Economics, And Science In The Nineteenth And Twentieth Centuries, Sarah Heavren

History & Classics Undergraduate Theses

The tale of the American chestnut tree offers incredible insight on Americans’ changing relationship with their environment and the complications added by economic motivations and scientific advancements. The American chestnut tree was known for its favorable timber and delectable nuts, which allowed the tree to assume a level of economic and cultural significance in twentieth century America. The timber was versatile and durable, and picking chestnuts and roasting them during the holidays were common seasonal traditions. However, the arrival of an invasive species of fungus at the beginning of the twentieth century decimated the population of American chestnut trees along …

Oil-Producing Metabolons Containing Dgat1 Use Separate Substrate Pools From Those Containing Dgat2 Or Pdat, Anushobha Regmi, Jay Shockey, Hari Kiran Kotapati, Philip D. Bates

Faculty Publications

© 2020 American Society of Plant Biologists. All rights reserved. Seed triacylglycerol (TAG) biosynthesis involves a metabolic network containing multiple different diacylglycerol (DAG) and acyl donor substrate pools. This network of pathways overlaps with those for essential membrane lipid synthesis and utilizes multiple different classes of TAG biosynthetic enzymes. Acyl flux through this network ultimately dictates the final oil fatty acid composition. Most strategies to alter seed oil composition involve the overexpression of lipid biosynthetic enzymes, but how these enzymes are assembled into metabolons and which substrate pools are used by each is still not well understood. To understand the …

Although koetjapic acid has a promising anticancer potential, yet it is highly insoluble in aqueous solutions. To increase aqueous solubility of koetjapic acid, we have previously reported a chemical modification of koetjapic acid to potassium koetjapate (KKA). However, pharmacokinetics of KKA has not been studied. In this study, pharmacokinetics and antiangiogenic efficacy of KKA are investigated. Methods: Pharmacokinetics of KKA was studied after intravenous and oral administration in SD rats using HPLC. Anti-angiogenic efficacy of KKA was investigated in rat aorta, human endothelial cells …

An Evaluation Study Of A Youth Entrepreneurship Program’S Influence On Self-Efficacy And Life Skills, Lauren S. Hopkins

Doctor of Education (Ed.D)

Youth entrepreneurship programs provide opportunities to learn and to practice strategies that are necessary to start and grow a business. In the summer of 2018, a nonprofit organization in central South Carolina facilitated a modified two-week entrepreneurship education program for 18 students who recently completed third through twelfth grades. Program managers wanted to conduct a program evaluation to determine the effectiveness of the modified program and its influence on the self-efficacy and life skills of the youth participants. Quantitative data were collected from measures of young people’s self-efficacy and life skills before and after the program, from entrepreneurial knowledge after …

Endophyte-Infected Tall Fescue Affects Rumen Microbiota In Grazing Ewes At Gestation And Lactation, Jianmin Chai, Saleh Alrashedi, Ken Coffey, Joan Burke, Kristina M. Feye, Steven C. Ricke, Si Hong Park, J. Lannett Edwards, Jiangchao Zhao

Animal Science Faculty Publications and Presentations

Tall fescue (Schedonorus arundinaceus) is a cool-season perennial grass that is widely used as a forage for many livestock species including sheep. An endophyte (Neotyphodium coenophialum) in tall fescue produces ergot alkaloids that enhance plant survival but produce toxicosis in animals. The objective of this study was to investigate the rumen microbiota from gestation and lactation in ewes grazing tall fescue pastures with high (HA) or moderate (MA) levels of endophyte infection, and their relationship with serum parameters. Data were collected at the beginning of the study (d1), the week before initiation of lambing (d51), and at …

Effects Of A Physical Activity Intervention On The Stress Reduction Of Underserved Adolescent Youth, Gwenyth C. Asbury

Senior Theses

Stress levels of American teenagers are rising. Studies show that teens are reporting higher stress levels than what they perceive to be healthy and that these levels are higher than the levels of perceived stress reported by adults (APA, 2013). In addition to reporting unhealthy levels of stress, adolescents are reporting feeling overwhelmed and depressed due to their stress (APA, 2013). These findings are especially true for underserved adolescents who are more likely to have exposure to violence, discrimination, racism and conditions of poverty in addition to experiencing the typical stressors associated with adolescence (American Academy of Child and Adolescent …

Isolation And Characterization Of A Novel Thermo-Solvent-Stable Lipase From Pseudomonas Brenneri And Its Application In Biodiesel Synthesis, Priyanka Priyanka, Gemma K. Kinsella, Gary T. Henehan, Barry J. Ryan

Articles

Pseudomonads are one of the most studied species of bacteria as they display remarkable metabolic and physiological versatility. This enables them to colonize a wide variety of terrestrial and aquatic habitats, generating biotechnologically interesting enzymes. Here, the partial purification and characterization of a novel, extracellularly-produced, lipase from Pseudomonas brenneri is described. The partially purified lipase was active over a broad pH range (5.0–9.0) and was stable at 70 °C for 45 min. The lipase displayed significant stability, and in some cases activation, in the presence of organic solvents with log P≥2.0. Such stability characteristics indicated that this lipase could potentially …

Interests And Priorities In Sockeye Salmon Management: How Are Policies Enacted And Interpreted On Three Alaskan Rivers?, Jake P. Palazzi

University Honors Theses

The large export abundance of Alaskan salmon is well documented, and many studies have been performed to assess the economic and environmental viability of the industry and its management. Less research has been done to characterize how state intentions regarding fisheries allocation are conceived of by management or perceived by vulnerable groups in the user pool. This study seeks to qualitatively characterize the disconnect between state and Native Alaskan perceptions of management effectiveness, public interest, and Native Alaskan involvement using interviews. Results showed that Native Alaskan and state manager respondents had very different perceptions of management effectiveness and equity. When …

Global Patterns In Seagrass Herbivory: Why, Despite Existing Evidence, There Are Solid Arguments In Favor Of Latitudinal Gradients In Seagrass Herbivory, K. L. Heck Jr, M. Samsonova, A. G. B. Poore, Glenn A. Hyndes

Research outputs 2014 to 2021

The ecological paradigm that biological interactions are more intense in the tropics than in temperate or polar regions has existed since the mid-twentieth century, but several recent meta-analyses have provided scant evidence for latitudinal gradients in the intensity of herbivory. This contradictory evidence led us to carefully review the data and results of several of those papers that failed to find latitudinal gradients in rates of seagrass herbivory. To re-evaluate the arguments around the presence or absence of latitudinal gradients in herbivory in seagrass, we began by expanding the selection criteria to include more studies to compare the published latitudinal …

Nlrp3 Inflammasome Signaling Regulates The Homing And Engraftment Of Hematopoietic Stem Cells (Hspcs) By Enhancing Incorporation Of Cxcr4 Receptor Into Membrane Lipid Rafts, Mateusz Adamiak, Ahmed K. Abdel-Latif, Kamila Bujko, Arjun Thapa, Krzysztof Anusz, Michał Tracz, Katarzyna Brzezniakiewicz-Janus, Janina Ratajczak, Magda Kucia, Mariusz Z. Ratajczak

Internal Medicine Faculty Publications

Fast and efficient homing and engraftment of hematopoietic stem progenitor cells (HSPCs) is crucial for positive clinical outcomes from transplantation. We found that this process depends on activation of the Nlrp3 inflammasome, both in the HSPCs to be transplanted and in the cells in the recipient bone marrow (BM) microenvironment. For the first time we provide evidence that functional deficiency in the Nlrp3 inflammasome in transplanted cells or in the host microenvironment leads to defective homing and engraftment. At the molecular level, functional deficiency of the Nlrp3 inflammasome in HSPCs leads to their defective migration in response to the major …

A Summary Of Current Research Into Neurodegenerative Disorders Using Drosophila Melanogaster, Chase Cortese

Honors Theses

Neurodegenerative disorders such as Alzheimer’s disease are characterized by damage to neural cells causing widespread neurological deficits. Historically, these diseases were deemed as inevitable declines in cognitive and neurological function that occurred with aging. Recent research has revealed, however, that these diseases have molecular bases allowing potential clinical intervention. The groundbreaking discoveries have been made using differing model organisms, which can replicate the phenotype and physiological cause of these disorders. One major model organism that has been used is the fruit fly, Drosophila melanogaster. They have served various roles in elucidating gene pathways and neurophysiological bases seen in these diseases. …

Growth Mindset Messaging In Stigma-Relevant Contexts: Harnessing Benefits Without Costs, Crystal L. Hoyt, Jeni L. Burnette

Psychology Faculty Publications

Growth mindsets are increasingly used to promote learning, development, and health. The increased popularity resulted in scrutiny and disputes about utility. The current work reviews a perspective critical to the debate. Namely, we focus on emerging research that examines both the favorable and potentially adverse consequences of growth mindset messaging in stigma-relevant contexts. This double-edge sword model merges the mindset perspective with attribution theory and the psychological essentialism literature. In stigmatizing contexts and in isolation, growth mindsets can indirectly predict lesspositive outcomes, via personal responsibility for the problem, but more positive outcomes, via expectations for the potential to manage …

Fostering Resilience In Correctional Officers, Jon Thomas Arthur Gist

Theses and Dissertations

A significant portion of the literature regarding corrections emphasizes the negative factors and outcomes related to the job. The career of a correctional officer includes a stressful, demanding, and unpredictable work environment. Correctional institutions are struggling to keep a correctional staff that can adapt to internal and external forces. Several studies have shown that correctional officers frequently encounter severe inmate misconduct, resulting in high levels of stress, low job satisfaction, and intentions of leaving the job. However, research begs the question of what makes a correctional officer resilient and functional at work?

No prior study has applied a mixed-methods study …

Identifying The Unique Characteristics Of First-Generation College Students Whose Parents Never Attended College, Reena Patel

Theses and Dissertations

In this descriptive study, I examined data from the Bill and Melinda Gates Millennial Scholars Cohort 3 Longitudinal Survey which comprised of high- achieving, low-income and historically marginalized college students, to compare students whose parents never attended college (“True” FCGS) to students whose parents attended but did not graduate along five variables: academic preparation, academic transition, academic and social integration, and academic outcome patterns. This study addressed a significant void in prior research with respect to the need for a clearly established FGCS definition. Bourdieu’s social and cultural capital framework is the theoretical foundation for this study because his theory …

Early-Onset Colorectal Cancer In Mice, Qi Zhang

Theses and Dissertations

Early-onset colorectal cancer (EOCRC) is the second most common cancer and the third leading cause of cancer mortality in people under 50 years old in the United States. Our hypothesis is that a high-fat diet (HFD), Allura Red AC, and/or psychological stress causes distal and rectal colon inflammation, which are associated with dysbiosis. Furthermore, chronic exposure to one or more of these elements increases the risk of EOCRC. A/J inbred mice were utilized in this study. The results are consistent with our hypothesis.

Overall findings are the following: (1) An HFD increased inflammatory scores and polyps’ burden in the distal …
