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 …

Consumption Pressure In Estuaries Peaks At Intermediate Salinities, Catherine E. De Rivera, Amy A. Larson, Benjamin G. Rubinoff, Luna R. Soto, Seth L. Wright, Edwin D. Grosholz, Gregory M. Ruiz, Andrew L. Chang

Environmental Science and Management Faculty Publications and Presentations

The nature and strength of biotic interactions change along stress gradients, but the importance of these interactions across estuarine gradients is under studied. Here, we examined how consumption varies across estuarine salinity gradients by deploying standardized baits (‘squidpops’) to measure consumption pressure along the gradients of five estuaries in Oregon, USA. The relationship between consumption and stress was nonlinear: consumption pressure peaked slightly at mid salinity and decreased at low salinity, especially as temperature increased, in the five estuaries studied. This finding does not support either of two existing models for consumption across gradients, including the Consumer Stress Model and …

Urban Heterogeneity Drives Dissolved Organic Matter Sources, Transport, And Transformation From Local To Macro Scales, Rebecca L. Hale, Kristina G. Hopkins, Krista A. Capps, John S. Kominoski, Jennifer L. Morse, Allison H. Roy, Shuo Chen, Annika Quick, Andrew J. Blinn, Liz Ortiz Muñoz, Gwendolynn Folk

Environmental Science and Management Faculty Publications and Presentations

Urbanization reshapes dissolved organic matter (DOM) sources, transport, and transformations through changes in vegetation, hydrology, and management of waste and water. Yet the impacts of urbanization on DOM are variable within and among cities. Predicting heterogeneous responses to urbanization is challenged by diverse human activities and underlying biophysical variation along stream networks. Using data from the 486 largest urban areas in the continental United States and seven focal cities, we identified macro and local scale urban gradients in social, built, and biophysical factors that are expected to shape DOM. We used these gradients and the literature to develop hypotheses about …

The Fascist Economic Paradox: Countering And Co-Opting Capitalism And Socialism In Interwar Europe, Vicente Pérez Catalán

History Undergraduate Departmental Honors Theses

One of the ambiguities within the study of fascism and political history in the 20th century is defining, in logical terms, the development of a coherent fascist economic identity. Three fascist governments will be examined in this project, Nazi Germany, Fascist Italy, and Vichy France, with the goal of understanding if there is indeed a distinction on their exertion of economic power as opposed to other ideological systems that could aid outlining fascism not merely as a political or philosophical doctrine, but perhaps also an economic one.

This study examines the political background prior to the formation of the three …

Disability In Exile: The "Union Of Russian Invalids" In Interwar Bulgaria And Yugoslavia, Evguenia Davidova

History Faculty Publications and Presentations

This article examines the post-war experience of a specific group of war veterans: the Russian refugees after the October Revolution in 1917. What happened when disabled veterans were stateless and dispersed among several foreign states? The focus is on comparing interwar Bulgaria and Yugoslavia, two countries on opposite sides of the Great War. There the refugees established various societies, mostly dominated by the military. Drawing on unpublished archival sources, this article investigates how the Russian societies for disabled persons functioned at four levels: amid the other Russian associations in Bulgaria and Yugoslavia; among the greater diaspora known as “Russia Abroad”; …

Does Coil Build Social Capital? Trust, Tolerance, And Political Engagement Among Students In The Usa And Uae, Lindsay J. Benstead, Kristina Katsos, Sally S. Mudiamu, Corinne Hughes

Politics and Global Affairs Faculty Publications and Presentations

Despite technological innovation and the COVID-19 pandemic, there is a dearth of experimental research on the effects of virtual instruction. Using an original field experiment conducted among 100 UAE and USA students, we investigate how a Collaborative Online International Learning (COIL) project on international development shapes social trust, tolerance, and political engagement. In an experimental design, UAE-based students were randomly assigned to a group with either their classmates or, through online interaction, with USA-based students, while in a quasi-experimental design, USA-based students collaborated online with UAE-based students. UAE-based COIL students developed greater interpersonal trust of others in their society, but …

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. …

Capital Structure And Business Failure: The Collapse Of Canada’S Dome Petroleum, Bruce Gilley

Politics and Global Affairs Faculty Publications and Presentations

In popular lore, the failure of Canada’s once-biggest company, Dome Petroleum, was caused by the interventionist policies of the federal government or its misadventures drilling for oil in the Arctic. But these factors acted in varied ways on the company. Rather, corporate finance theories offer more insight into the dynamics that led to Dome’s takeover by the American oil major Amoco in 1988. Dome was unique in its unwillingness to issue new share capital during its growth phase and instead relied on easy debt financing. This in turn was a result of both insider preferences as well as capital market …

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 …

Spiritual Exercises In Novarodok Mussar And The Early Work, Martin Zwick

Complex Systems Faculty Publications and Presentations

This paper compares aspects of the teachings launched in pre-revolutionary and revolutionary Russia of two spiritual figures: Rabbi Yoseph Yozel Horwitz and George Gurdjieff. Yozel founded the Novarodok school of Mussar within Judaism; Gurdjieff founded the spiritual tradition known as “the Work” or “Fourth Way.” There are of course great differences between Judaism and the Work, but some similarities might be expected between spiritual disciplines, especially similarities in practice as opposed to doctrine. This paper explores similarities of some spiritual exercises in the Mussar school of Novarodok and secondarily in later or other Mussar teachings and in the early Gurdjieff …

Language, People, Classrooms, World: Blending Disparate Theories For United Language Education Practices, Masatoshi Sato, Steven L. Thorne, Marije Michel, Theodora Alexopoulou, John Hellermann

World Languages and Literatures Faculty Publications and Presentations

With a forward‐looking and problem‐solving mindset, this article aims to combine theoretical knowledge and empirical evidence from different schools of thought in the field of second language (L2) learning and teaching—namely, instructed second language acquisition, generative linguistics, and an ecological perspective that includes multiple frameworks. Acknowledging numerous fundamental differences in our theoretical and methodological perspectives on how to conduct research, we are united on two fronts: First, we believe that researchers with differing theoretical commitments can and should work together to advance L2 research. Second, differing theoretical beliefs are potentially of limited relevance to those who will implement our pedagogical …

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.

A 14-Year Content Analysis Of School-Family Partnership Publications In Counseling: Trends, Gaps, And Future Directions, Yi-Wen Su, Dan Li

Counselor Education Faculty Publications and Presentations

This content analysis examined 55 articles on school-family-community partnerships published in counseling journals between 2010 and 2024, identifying trends in publication type, methodology, and population focus. Most articles (54.54%) were conceptual, with Professional School Counseling leading in publication volume. Limited empirical research and a lack of focus on diverse populations were noted, with only 18.18% addressing racial minorities (primarily Latino and African American) and 5.45% focusing on rural communities. Four primary strategies for strengthening partnerships emerged: Inclusivity, Leadership and Empowerment, Equity-Focused, and Consistent Communication—each aligning with the school counselor’s roles in fostering collaborative, equitable partnerships. Recommendations emphasize a need for …

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 …

Rising Tides Lift All Boats: Significant Disproportionate Identification Of Latine Students In The Eligibility Category Of Specific Learning Disability, Erica Gordon

"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.

Old Habits Die Hard: Precedent, Psychology, And The Admissibility Of Forensic Evidence, Sara Gordon

All Faculty Publications

Forensic evidence, long considered a cornerstone of criminal justice, has faced increasing scrutiny as recent studies and reports expose significant flaws in its scientific foundation. Techniques such as latent fingerprint analysis, microscopic hair comparison, and ballistics matching, which had been widely accepted for decades, are now being challenged for their lack of empirical validation. Reports by the National Research Council and the President’s Council of Advisors on Science and Technology have highlighted the deficiencies in these forensic methods, calling into question their reliability and the weight they are given in courtrooms. Yet despite the growing acknowledgement of widespread issues affecting …

Policy Forum: Are Carbon Contracts For Difference Well Suited For Canada?, Wei Cui

All Faculty Publications

At least up to the release of the federal 2024 budget, many Canadian politicians, climate policy think tanks, and industry groups promoted carbon contracts for difference (CCfD) to complement carbon pricing. This commentary urges caution against the broad adoption of CCfDs. The author begins by noting that the current designs of provincial output-based pricing systems (OBPS) are not consistent with the expectation of the systems delivering robust price signals. He argues that CCfDs depend on such price signals, and they are not a plausible policy for encouraging the emergence of such signals. The author then argues that it is hard …

Binding Rights: Contractual Federalism And The Right To Housing In Canada, Alexandra Flynn

All Faculty Publications

Canada’s housing crisis continues to deepen, exacerbated by constitutional fragmentation and intergovernmental reluctance to implement human rights-based housing policy. While the federal National Housing Strategy Act recognizes housing as a human right, its application is limited and its legal force is limited to the federal level, leaving provinces and municipalities unbound. This article argues that contract law – particularly conditional funding agreements between the federal government and subnational actors – can serve as a pragmatic and legally coherent mechanism to bind municipalities to housing obligations, including the recognition of housing as a human right. Drawing on the Canada Health Act …

Ethno-Psychometry: The Measurement Of Personality In Mexico, Rolando Diaz-Loving

Online Readings in Psychology and Culture

Following in the tradition of ethno-psychological research proposed by Diaz-Guerrero (1986, 1989, 1993, 1994, 1995), this manuscript delineates the process toward obtaining statistically and conceptually valid and reliable personality measures, that at the same time are also culturally relevant and sensitive to the Mexican culture. The methods and construct development for the creation of multidimensional measures of achievement orientation, empathy, locus of control, assertiveness, masculinity, femininity, and self-concept are presented. Further information on the specific characteristics of measures, their construct and convergent, divergent, and predictive validity can be found in Diaz-Loving (2019).

Antimicrobial Susceptibility And Molecular Characterization Of Corynebacterium Pseudotuberculosis Isolates Recovered From Caseous Lymphadenitis In Sheep, Mohamed Bakr, Mahmoud E. Hashad, Islam Gomaa

Nanotechnology Research Centre

Corynebacterium pseudotuberculosis is a well-recognized etiological agent responsible for caseous lymphadenitis (CLA) and ulcerative lymphangitis (UL) in small and large ruminants, respectively. This pathogen is frequently associated with poor therapeutic outcomes in animals. In the present study, 30 bacterial isolates, recovered from 300 lymph node and pus samples (10%), were identified as Corynebacterium spp. Molecular confirmation using 16S rRNA and pld gene PCR verified 11 of these isolates as C. pseudotuberculosis, while one isolate was identified as C. jeikeium, a first record from sheep in Egypt. The isolates were subjected to antimicrobial susceptibility and genotyping using enterobacterial repetitive intergenic consensus-polymerase …

Artificial Intelligence And Music Mash-Ups: Monetizing An Opt-In Closed Universe Database To Preserve Royalties And Credit For Composer And Sound Recording Rights Holders, Michael M. Epstein

Marquette Law Review

This Article charts the development of an opt-in database of music publishing and sound recording catalogues that would allow music industry stakeholders to profit from those who use artificial intelligence to generate new creative content from existing intellectual property. The database would be a portal to content that rights holders would consent to include in a library made available to the public. The database could be advertiser-supported, allowing for no-cost access by the public, or users could pay for a blanket license or per- search fee. Proceeds from the database would be distributed to rights holders based on the content …
