Preparing Researchers To Conduct Interdisciplinary, Multi-Method Qualitative Research, Kathryn Roulston

The Qualitative Report

In this paper I outline ideas for how qualitative research methods might be taught in ways that value difference, promote dialogue, and encourage graduates to engage actively in their disciplines to promote the benefits of qualitative inquiry, locally, nationally and globally. I argue for approaches to teach qualitative inquiry in ways that value (1) interdisciplinarity, in that teaching draws on multiple epistemologies and theoretical approaches to inquiry developed across disciplines; (2) diversity in methodological approaches, in that teaching explores multiple methods to respond to research questions that are continually subject to revision, innovation, and critical analysis; and (3) the knowledge …

Autophagy Modulation As A Treatment Of Amyloid Diseases, Zoe Mputhia, Eugene Hone, Timir Tripathi, Tim Sargeant, Ralph Martins, Prashant Bharadwaj

Research outputs 2014 to 2021

Amyloids are fibrous proteins aggregated into toxic forms that are implicated in several chronic disorders. More than 30 diseases show deposition of fibrous amyloid proteins associated with cell loss and degeneration in the affected tissues. Evidence demonstrates that amyloid diseases result from protein aggregation or impaired amyloid clearance, but the connection between amyloid accumulation and tissue degeneration is not clear. Common examples of amyloid diseases are Alzheimer's disease (AD), Parkinson's disease (PD) and tauopathies, which are the most common forms of neurodegenerative diseases, as well as polyglutamine disorders and certain peripheral metabolic diseases. In these diseases, increased accumulation of toxic …

Continuous Free Cortisol Profiles In Healthy Men - Validation Of Microdialysis Method, R Bhake, Gm Russell, Y Kershaw, K Stevens, Et Al

Peninsula Medical School

Context In humans, approximately 95% of circulating cortisol is bound to corticosteroid-binding globulin and albumin. It is only the free fraction that is biologically active and can activate signaling pathways via glucocorticoid hormone receptors in cells. Microdialysis is a well-established technique that enables the sampling of molecules in different compartments of the body, including extracellular fluid. This is the first study validating a rapid sampling microdialysis method measuring free cortisol in the subcutaneous and blood compartments of healthy volunteers. Methods Healthy nonsmoking volunteers (42 men, aged 18–24 years; body mass index 18–25 kg/m2) received placebo (saline), 250 μg Synacthen, or …

Immobilization Of Heavy Metals By Microwave Torrefaction Of Sewage Sludge With Additives, Jiri Holatko

Bio-Char II: Production, Characterization and Applications

The treatment of sewage sludge (SS) is one of the most important issues of the circular economy strategy in the European Union and in the Czech Republic (CR). New legislation in the CR strictly regulates the SS landfilling and its direct application in agriculture. One of the most important limiting factors for the use of SS in agriculture are the heavy metals (HMs). Thermal transformation of SS, especially pyrolysis and torrefaction, typically provides pyrolysis oil, pyrolysis gas (syngas), and solid carbonaceous product called either biochar (when used in agriculture) or charcoal. The quality of the biochar depends strongly on the …

Abundance Estimation From Multiple Data Types For Groupliving Animals: An Example Using Dhole (Cuon Alpinus), Dusit Ngoprasert, George A. Gale, Andrew J. Tyre

School of Natural Resources: Faculty Publications

Large carnivores are declining globally and require baseline population estimates for management, however large-scale population estimation is problematic for species without unique natural marks. We used camera trap records of dhole Cuon alpinus, a group-living species, from three national parks in Thailand as a case study in which we develop integrated likelihood models to estimate abundance incorporating two different data sets, count data and detection/non-detection data. We further investigated relative biases of the models using different proportions of data with lower versus higher quality and assessed parameter identifiability. The simulations indicated that the relative bias on average across 24 tested …

Biochar Beyond Carbon Sequestration: Life-Cycle Emission Reductions, Nutrient Recycling And Food Security, Johannes Lehmann

Bio-Char II: Production, Characterization and Applications

Carbon dioxide withdrawal from the atmosphere is increasingly seen as an indispensable approach to mitigate climate change in concert with emission reductions from fossil fuel use. Conversion of biomass into biochar decreases mineralizability by one to two orders of magnitude and typically constitutes half of life-cycle emission reductions of biochar systems focusing on crop or forestry residues. In addition, emission reductions related to changes in nitrous oxide emissions or photosynthesis may contribute to climate change mitigation. While impacts of pyrolyzing carbon-rich crop or forestry residues on greenhouse gas emissions have been widely investigated, less attention has been paid to nutrient-rich …

Digital Divide Among Caregivers Of Chronic Disease Patients, Ayokunle Olagoke, Harveen Kaur, Ashley M. Hughes

Health and Kinesiology Faculty Publications

Expansive and rapid growth of technology creates unprecedented patient access to health information, including timely communication with care providers via patient portals and the ability to access information regarding specific disease(s) (e.g., cancer). However, several forms of digital engagement with health providers require access and use of reliable internet access. A “digital divide” is used to describe demographic differences which contribute to a patient’s use or disuse of patient portals; prior research have noted disparities in lack of reliable internet access. Despite the prevalence of informal caregivers in patient care, little is known about internet access and use among informal …

Red Oak Seedlings As Indicators Of Deer Browse Pressure: Gauging The Outcome Of Different White-Tailed Deer Management Approaches, Bernd Blossey, Paul Curtis, Jason Boulanger, Andrea Davalos

Biology Faculty Publications

After decades of high deer populations, North American forests have lost much of their previous biodiversity. Any landscape‐level recovery requires substantial reduc‐ tions in deer herds, but modern societies and wildlife management agencies appear unable to devise appropriate solutions to this chronic ecological and human health crisis. We evaluated the effectiveness of fertility control and hunting in reducing deer impacts at Cornell University. We estimated spring deer populations and planted Quercus rubra seedlings to assess deer browse pressure, rodent attack, and other factors compromising seedling performance. Oak seedlings protected in cages grew well, but deer annually browsed ≥60% of unprotected …

Fisetin, A 3,7,3',4'-Tetrahydroxyflavone Inhibits The Pi3k/Akt/Mtor And Mapk Pathways And Ameliorates Psoriasis Pathology In 2d And 3d Organotypic Human Inflammatory Skin Models, Jean Christopher Chamcheu, Stephane Esnault, Vaqar M. Adhami, Andrea L. Noll, Sergette Banang-Mbeumi, Tithi Roy, Sitanshu S. Singh, Shile Huang, Konstantin G. Kousoulas, Hasan Mukhtar

Faculty Publications

Psoriasis is a chronic immune-mediated skin disease that involves the interaction of immune and skin cells, and is characterized by cytokine-driven epidermal hyperplasia, deviant differentiation, inflammation, and angiogenesis. Because the available treatments for psoriasis have significant limitations, dietary products are potential natural sources of therapeutic molecules, which can repair the molecular defects associated with psoriasis and could possibly be developed for its management. Fisetin (3,7,3',4'-tetrahydroxyflavone), a phytochemical naturally found in pigmented fruits and vegetables, has demonstrated proapoptotic and antioxidant effects in several malignancies. This study utilized biochemical, cellular, pharmacological, and tissue engineering tools to characterize the effects of fisetin on …

Imatinib Mesylate Effects On Zebrafish Reproductive Success: Gonadal Development, Gamete Quality, Fertility, Embryo-Larvae Viability And Development, And Related Genes, Nader Ahmadi, Seyed-Mohammadreza Samaee, Robert A. Yokel, Aliasghar Tehrani

Pharmaceutical Sciences Faculty Publications

Imatinib (IM) is a tyrosine kinase (TK) inhibitor (TKI) used to treat chronic myeloid leukemia. Clinical case reports and a few laboratory mammal studies provide inconclusive evidence about its deleterious effects on reproduction. The aim of the current study was to evaluate the potential of zebrafish to characterize IM-induced effects on reproduction and clarify IM effects on reproductive success. To this end, we exposed adult zebrafish to four concentrations of IM for 30 days followed by a 30-day depuration period. IM exposure caused a concentration-dependent, irreversible, suppression of folliculogenesis, reversible decrease in sperm density and motility, decreased fecundity and fertility, …

Rapid Microwave-Assisted Biomass Delignification And Lignin Depolymerization In Deep Eutectic Solvents, Pranjali D. Muley, Justin K. Mobley, Xinjie Tong, Brian Novak, Joseph Stevens, Dorel Moldovan, Jian Shi, Dorin Boldor

Faculty Publications

Biomass deconstruction and lignin depolymerization was performed using three different deep eutectic solvents. Various temperature (110°, 130°, and 150 °C) and time (1, 5, 10, 15 min) conditions were tested in a 2450 MHz microwave reactor. Oxalic acid (130 °C, 15 min) and formic acid DES (150 °C, 15 min) gave the highest lignin yield. Microwave heating reduced the processing time significantly. NMR characterization shows that microwave heating promotes selective bond cleavage during lignin depolymerization and has a narrow molecular weight distribution compared to conventional heating techniques. Molecular dynamic simulations showed that certain lignin bonds are stretched under the electric …

A Patterning Approach To Complexity Thinking And Understanding For Students: A Case Study, Shae L. Brown

Northeast Journal of Complex Systems (NEJCS)

Complexity thinking and understanding are vital skills for young people in these times of uncertainty and change. Such skills contribute to resilience and capacities for adaptivity and innovation. Within my teaching practice I have found students to be aware of complex dynamics, uncertainty and change, both in their lives and in the world. However, the current curriculum lacks language and process to conceptualise, articulate and develop complexity understanding. To address this problem, I developed and introduced a patterns-based design and process to a cohort of Australian secondary students. Comprising flowform patterning together with ecological metaphors, the design forms a conceptual …

Effects Of Land-Use Change And Prey Abundance On The Body Condition Of An Obligate Carnivore At The Wildland-Urban Interface, Courtney A. C. Coon, Bradley C. Nichols, Zara Mcdonald, David C. Stoner

Wildland Resources Faculty Publications

Land-use change represents a primary driver of carnivore population declines, yet some large carnivore species have acclimated and persist within anthropogenically altered landscapes. Previous attention has been focused on the genetic and behavioral implications of land-use changes, but few studies have investigated how human development impacts animal physiology and health. Here we examined how body condition scores of a widely distributed North American carnivore, the puma (Puma concolor), are affected by anthropogenic habitat modification. For this study we collected 252 puma camera trap events across a land-use gradient in the San Francisco Bay Area. We found that pumas …

Modeling Information Anxiety, Muhammad Asif Naveed, Mumtaz Ali Anwar

Library Philosophy and Practice (e-journal)

This paper traces the historical developments using selected literature related to ‘library anxiety’, ‘information seeking anxiety’ and ‘information anxiety’. These concepts existed independently and parallelly and attracted much attention from the researchers of their respective fields. The existing literature lacked a study establishing a relationship among these three concepts which led to the idea of a general model of information anxiety to inform researchers as well as professionals dealing with policy and practice. This model represents information anxiety as the general and broader concept nesting information seeking anxiety as its sub-set and library anxiety as a further sub-set. It highlights …

Direct Conversion Of Mouse Fibroblasts Into Osteoblasts And Investigating Cobra1 Expression Responce, Walid Almoafy Alasar

Theses and Dissertations

Fibroblasts are the most common connective tissue cells and are responsible for the synthesis of extracellular matrix (ECM) and collagen. They are mainly of mesenchymal stem cells (MSCs) origin. Fibroblasts are fully differentiated cells although some recent findings reported that fibroblasts possess some potency that allows them to differentiate into other cells types. They are said to undergo adipogenic, chondrogenic, hepatogenic, nurogenic and osteogenic differentiation if grown in the suitable conditions. In the normal physiologic environment, fibroblasts can also differentiate to epithelial cells, a phenomenon known as the mesenchymal epithelial transition (MET). In the current research, we induced L929 mouse …

Citation Rates For Ohio State Graduate Theses & Dissertations: Trends, Surprises, And Inaccuracies, Daniel S. Dotson

Library Philosophy and Practice (e-journal)

The Ohio State University’s holdings of graduate theses and dissertations were examined to determine if highly-downloaded titles tended to be highly-cited. The study found that citation rates were highly variable and did not necessarily correspond to download rates. This included very highly downloaded titles with low citation rates, and lesser-downloaded titles with high citation rates. The study found that Google Scholar, which was used to identify citation rates, too often counts theses and dissertations as a version of a different work with the same title, even if it is another format and sometimes with additional authors. This article will share …

Being In Uncertainties: An Inquiry-Based Model Leveraging Complexity In Teaching-Learning, Diane Rosen

Northeast Journal of Complex Systems (NEJCS)

Education is traditionally structured as a closed system, privileging result-driven methods that offer control and predictability. In recent decades this reductionist approach has been effectively challenged by interdisciplinary work in complex systems theory, revealing myriad levels of orderly disorder that make either-or, linear instruction an inadequate norm. Narrowing the broad implications of a complexity lens on education, this paper focuses on generative uncertainty in teaching-learning, a paradoxical state of epistemological and creative growth described by English poet John Keats as "the negative capability of being in uncertainties, mysteries, doubts." Opportunities to advance this potentiating capacity are especially abundant in constructivist …

Creativity As An Emergent Property Of Complex Educational System, Ceire Monahan, Mika Munakata, Ashwin Vaidya

Northeast Journal of Complex Systems (NEJCS)

The importance of creativity in education has been discussed often in the literature. While there remains no agreed-upon definition of creativity, the psychological literature points to traits of a creative person. These include the ability to think outside the box, make connections between seemingly disparate ideas, and question norms. The literature provides several examples of classroom experiments to help foster creativity in the classroom. In science and mathematics, we can start by getting students to recognize mathematics and the sciences as being creative endeavors. While these attempts are noteworthy, they are not necessarily aligned with instructional practices. In this article, …
