Assessment And Validation: An Updated Climate Change Plausibility Perception Measure, Melike Hanedar, Gizem Ozyazici, Gaye Defne Ceyhan

Earth & Environmental Sciences - All Scholarship

Plausibility perceptions about climate change influence learner engagement, motivation, and knowledge acquisition, thereby shaping the effectiveness of climate change education. The Plausibility Perception Measure (PPM) was originally developed following the Fourth Assessment Report of the Intergovernmental Panel on Climate Change in 2007. There was a need to update the scale to measure individuals' plausibility perceptions regarding the current climate crisis. This study updated the PPM scale to reflect the IPCC's 2022 report on impacts, adaptation, and vulnerability. The updated PPM scale is a ten-point Likert scale consisting of 15 items. Data were collected from 330 pre-service teachers at a public …

Evaluation Of Alginate Hydrogel Microstrands For Stromal Cell Encapsulation And Maintenance., Sujith Chander Reddy Kollampally, Xulang Zhang, Nicholas Moskwa, Deirdre A Nelson, Susan T Sharfstein, Melinda Larsen, Yubing Xie

Faculty Research 2024

Mesenchymal stromal cells (MSCs) have displayed potential in regenerating organ function due to their anti-fibrotic, anti-inflammatory, and regenerative properties. However, there is a need for delivery systems to enhance MSC retention while maintaining their anti-fibrotic characteristics. This study investigates the feasibility of using alginate hydrogel microstrands as a cell delivery vehicle to maintain MSC viability and phenotype. To accommodate cell implantation needs, we invented a Syringe-in-Syringe approach to reproducibly fabricate microstrands in small numbers with a diameter of around 200 µm and a porous structure, which would allow for transporting nutrients to cells by diffusion. Using murine NIH 3T3 fibroblasts …

Trajectories Of Digital Flourishing In Adolescence: The Predictive Roles Of The Developmental Changes And Digital Divide Factors, Jasmina Rosič, Lara Schreurs, Sophie H. Janicke-Bowles, Laura Vandenbosch

Communication Faculty Articles and Research

Digital flourishing refers to the positive perceptions of digital communication use in five dimensions: connectedness, positive social comparison, authentic self-presentation, civil participation, and self-control. This three-wave panel study among 1081 Slovenian adolescents (M_age = 15.34 years, 53.8% boys, 80.7% ethnic majority) explored the trajectories of their digital flourishing dimensions over 1 year (2021–2022). Latent class growth analysis identified two classes. Adolescents in the first class reported high levels of digital flourishing, which remained stable over time, whereas those in the second class reported low levels of digital flourishing with decreased self-control over time. Autonomy-supportive restrictive, autonomy-supportive active, and …

Mapping Out The Sky, Erik Johnson

Natural Science Faculty

Astronomers are often asked to help identify UFOs. It's a reasonable request since the term means "unidentified flying object." An untrained observer may not know which celestial objects are visible at night, even in light-polluted skies. They may mistake a plane for a planet, a bright star, or a satellite.

Death, Sex, And Hope Through The Arts: Developing An Expressive Arts-Existential Therapy Method For The Treatment Of Compulsive Sexual Behavior Disorder, Michael Shirek

Expressive Therapies Capstone Theses

Compulsive sexual behavior disorder (CSBD) is a newly recognized disorder mired in a history of terminological and diagnostic controversy. Emerging research into the disorder has pointed to shame as an intrinsic motivator of the compulsive cycle, which provides potential for therapeutic intervention. Although most empirically-based treatments approach CSBD through a behavioral, abstinence-based model, an integrated expressive arts-existential therapy approach may provide opportunity for effective, person-centered treatment which mitigates the risk of reinforcing the shame cycle. For this capstone thesis, I developed and implemented a three-session treatment method which uses expressive arts therapy to investigate existential themes of guilt, non-being, isolation, …

Formerly Used Defense Sites On Unalaska Island, Alaska: Mapping A Legacy Of Environmental Pollution, Jennifer Schmidt

ISER Articles

Unalaska Island, Alaska, served as a US military base during World War II. The military installed bases on Unalaska and nearby islands, many of which were built adjacent to Unangan communities. The military used toxic compounds in its operations and left a legacy of pollution that may pose health risks to residents and local wildlife. The goals of this study were to identify hotspots of contamination remaining at Unalaska formerly used defense (FUD) sites, evaluate the risk posed by arsenic, and examine “no US Department of Defense action indicated” (NDAI) status determinations for FUD sites near communities. We compiled soil …

Discovery Of Strong 3-Nitro-2-Phenyl-2h-Chromene Analogues As Antitrypanosomal Agents And Inhibitors Of Trypanosoma Cruzi Glucokinase, Shane M. Carey, Destiny M. O’Neill, Garrett B. Conner, Julian Sherman, Ana Rodriguez, Edward L. D'Antonio

Natural Sciences Faculty Publications

Chagas disease is one of the world’s neglected tropical diseases, caused by the human pathogenic protozoan parasite Trypanosoma cruzi. There is currently a lack of effective and tolerable clinically available therapeutics to treat this life-threatening illness and the discovery of modern alternative options is an urgent matter. T. cruzi glucokinase (TcGlcK) is a potential drug target because its product, D-glucose-6-phosphate, serves as a key metabolite in the pentose phosphate pathway, glycolysis, and gluconeogenesis. In 2019, we identified a novel cluster of TcGlcK inhibitors that also exhibited anti-T. cruzi efficacy called the 3-nitro-2-phenyl-2H-chromene analogues. This was achieved by performing a target-based …

Habitat Suitability For Age-0 Lake Sturgeon In The Grand River, Benjamin D. Gunnett

Masters Theses

Lake sturgeon (Acipenser fulvescens) are a state-threatened species in Michigan and have become a focus for conservation. The lower Grand River is home to a remnant population of lake sturgeon between the 6th Street dam in downtown Grand Rapids and Lake Michigan. There has been limited research on age-0 lake sturgeon habitat use in low-gradient and more turbid rivers. To address this deficit, we developed a Habitat Suitability Index (HSI) for age-0 lake sturgeon based on prior literature in the Great Lakes. A HSI combines parameters representing in-stream habitat characteristics to score habitat suitability on a scale of 0-1, 0 …

If You Choose Not To Decide... Alaska’S Budgeting Process In 2023, Glenn Wright

Faculty, Staff, and Students

Alaska in 2023 is experiencing the first results of the new election system—the top-four all-party primary and Ranked Choice Voting. So far, that system seems to be generating results consistent with what advocates expected; a more moderate and collegial policy-making environment, and possibly even more sensible budgetary policy. This, coupled with relatively strong (though declining) oil prices, and abundant sovereign wealth led to a relatively low-drama, low-conflict budgeting process in spring 2023, as well as relatively moderate budgeting outcomes.

Chitosan-Based Hydrogels In Drug Delivery, Salma A. Fereig, Mona Mohamed Ahmed Abdelmottaleb

Pharmacy

Hydrogels are three-dimensional cross-linked hydrophilic polymers that are able to absorb large quantities of water and swell. They have various properties like biocompatibility, low toxicity, and mostly biodegradability, which make them attractive for drug delivery applications. Chitosan hydrogels are especially attractive due to the inherent activities of the chitosan itself like the antibacterial, anti-inflammatory, and tissue regeneration enhancement capacity. Therefore, chitosan hydrogels have been proposed for the delivery of various drugs, genes, cytokines, and stem cells via various routes of administration for the treatment of various diseases as well as different forms of degeneration.

Gucy2c Signaling Limits Dopaminergic Neuron Vulnerability To Toxic Insults, Lara Cheslow, Matthew Byrne, Jessica Kopenhaver, Lorraine Iacovitti, Richard Smeyne, Adam Snook, Scott Waldman

Farber Institute for Neuroscience Faculty Papers

Mitochondrial dysfunction and reactive oxygen species (ROS) accumulation within the substantia nigra pars compacta (SNpc) are central drivers of dopaminergic (DA) neuron death in Parkinson's disease (PD). Guanylyl cyclases and their second messenger cyclic (c)GMP support mitochondrial function, protecting against ROS and promoting cell survival in several tissues. However, the role of the guanylyl cyclase-cGMP axis in defining the vulnerability of DA neurons in the SNpc in PD remains unclear, in part due to the challenge of manipulating cGMP levels selectively in midbrain DA neurons. In that context, guanylyl cyclase C (GUCY2C), a receptor primarily expressed by intestinal epithelial cells, …

A Critical Review Of Sociological Research On Sexual Pleasure, Hannah Regan

Faculty Scholarship

Sociologists of sexuality often invoke the theme of pleasure, but it is not always clear what scholars believe the implications and importance of pleasure are. To this end, this paper reviews the existing literature on sexual pleasure, specifically within the field of sociology, to demonstrate what questions about sexual pleasure are (and are not) currently being asked. Through a systematic literature review, I demonstrate that scholars often lack a justification for why pleasure is important. I also connect themes between the kind of questions being asked about pleasure and the justifications attached to these studies, relating to risk mitigation, relationship …
