This study examines the potential for retinal regeneration by assessing current research on Müller glial cell differentiation and stem cell-based treatments. An analysis of experimental studies and therapeutic advancements highlights the mechanisms observed in regenerative models such as zebrafish and chicks, in contrast to the reactive gliosis and glial scarring observed in humans. Findings suggest that therapies such as optogenetics and stem cell transplantation have partially restored vision; however, their limitations stem from an inability to fully …

Can Cystic Fibrosis Be Treated With Genetic Therapy?, Steve Silverberg

The Science Journal of the Lander College of Arts and Sciences

This paper discusses the current and prospective treatment options for the fatal genetic disease cystic fibrosis. Cystic fibrosis (CF) is a rare recessive genetic disorder that is caused by a mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, which codes for a protein that is on the surface of a cell. This protein allows for the flow of chloride, bicarbonate, and sodium ions to pass through the cell wall, bringing water with it. When this protein doesn’t work, the lack of ions and water in extracellular fluid becomes too thick, causing a multitude of problems. The most common …

Risk Factors Of Covid-19 Mortality, Ellie Wolff

Methods to extract and analyze data included literature review using existing studies such as peer-reviewed articles and reports from PubMed, CDC, etc. By analyzing …

The Bidirectional Gut-Brain Axis: Impact Of Dysbiosis On Depression Through The Hpa Axis, Matan Shiller

The Science Journal of the Lander College of Arts and Sciences

Emerging research suggests that depression is not solely a brain disorder but is deeply influenced by the gut microbiome. The gut-brain axis (GBA) is a bidirectional communication system linking the gastrointestinal system and the brain, modulating mood, behavior, and mental health. Gut microbiota produce metabolites, such as short-chain fatty acids (SCFAs) and tryptophan catabolites, that influence neurotransmission and the stress response via the hypothalamic-pituitary-adrenal (HPA) axis. Dysbiosis, or microbial imbalance, disrupts these pathways, contributing to a major depressive disorder (MDD). Evidence from germ-free animal studies and fecal microbiota transplants (FMT) highlights the role of gut microbiota in emotional regulation and …

Will Malaysia Become An Active Middle Power?, Bruce Gilley

Politics and Global Affairs Faculty Publications and Presentations

Malaysia’s economic growth and democratisation since 2003 have vaulted it into the ranks of the middle powers in the international system. However, Malaysia remains hesitant about its middle power status. It has assumed a counterhegemonic or pro-multipolarity role; it has supported some new international rules and institutions; it leads regional governance institutions; and it advocates for small countries on development issues. However, these middle power behaviours are countered by a continuation of traditional Malaysia diplomacy which is inactive in shaping the emergence of superpower China as well as being disruptive and personalistic, most recently because of its embrace of radicalisms. …

Displaced: Distinguishing Housing Outcomes From Judicial Outcomes In Oregon’S Eviction Cases, Colleen Carroll, Minji Cho, Lisa K. Bates

Urban Studies and Planning Faculty Publications and Presentations

In an eviction case, the tenant’s housing outcome refers to whether the tenant remains in their home (the unit) at the end of the eviction process. At the end of the eviction process, either the tenant remained in the home or was displaced. Unfortunately, housing outcomes are not systematically recorded as part of the eviction process. In some cases, the tenant’s housing outcome is recorded in the case records or court documents, but this is not always consistent. To address this, we developed three categories of housing outcomes—remained, displaced, and undeterminable—to measure the outcomes of eviction cases filed in Multnomah …

Thorstein Veblen: The Independent Thinker Whose Contributions Advanced A Distinct Tradition Of Heterodox Economics, John B. Hall

Economics Faculty Publications and Presentations

Challenging Charles Camic’s perspective, this article argues that Thorstein Veblen’s time at the top amounted to about nineteen years; a fraction of his professional career. While drawing from and building upon challenges associable with a changing world which he faced – related to the ending of Laissez-faire and the rise of big business; the institutions initiated for prosecuting World War I; and the accompanying rise of the vested interests – Veblen’s writings effectively and propitiously provided a solid foundation for an American school of heterodox thought known as Original Institutional Economics.

Evading A Post-Truth World: Rorty’S Foundationless Philosophy For An Acculturating Education, Madhu Narayanan

Educational Leadership and Policy Faculty Publications and Presentations

A challenge for educators is how to teach in a “post-truth” world. Lies, fake news, and a gleeful disregard for facts – what I collectively term mis/information – all seem to undermine the very project of education. The pragmatism of Richard Rorty holds promise to address such issues. I first argue that Rorty’s philosophy of education is of limited use, whereas his broader thoughts on a philosophy without foundations are more relevant. I then suggest that a way forward is to evade the fight against post-truth dynamics altogether. An insistence on rational objectivity and foundational truth are at the root …

Statistical Investigation Of Gypsum Crystallization Kinetics, Azmain A. Akash

LSU Master's Theses

Gypsum, a naturally occurring mineral salt, is frequently encountered in industrial processes such as seawater desalination and power plant cooling. Over the years, significant effort has been devoted to controlling the crystallization of gypsum through various chemical approaches, including acidification, chelating agents, and antiscalant polymers. Nevertheless, the cost associated with chemical treatments may be reduced by incorporating physical operational strategies to complement chemical methods in regulating gypsum crystallization.

This study systematically examines the comparative roles of chemical and physical entropy in the gypsum crystallization process to elucidate their respective influences on gypsum growth kinetics. Chemical entropy is manipulated by adjusting …

Climate Change And Corporate Law In The United States: Not "Woke" But Eyes Open., Cynthia A. Williams

Articles by Maurer Faculty

This Essay discusses the evidence that climate change and nature loss create financially material risks for corporations that must be carefully considered by officers and directors pursuant to their fiduciary duties of loyalty and care. This analysis concludes that under the current state of fiduciary duty law and the known financial risks presented by climate change and nature loss, officers and directors of corporations may breach their fiduciary duties by failing to implement and monitor a robust system to identify and manage each type of industry-specific climate-related and nature related risk. Risk of breach is particularly acute for entity-specific compliance …

"17 Going On 23": Sentencing Young People To Life In Canada, Debra Parkes

All Faculty Publications

This paper analyzes reported Canadian cases from 2008 to 2022 in which young people were sentenced for murder. It shows that, at least in these reported decisions, sentencing young people as adults for murder is not rare. The Crown routinely seeks life sentences for young people and the court orders them in the vast majority of cases in which they are sought. Life sentences for young people have become normalized and expected in murder cases, rather than exceptional. This paper delves into the case law to get a better picture of why and how this is happening.
