Objective: While outcome from mild traumatic brain injury (mTBI) is generally favorable, concern remains over potential negative long-term effects, including impaired cognition. This study examined the link between cognitive performance and remote mTBIs within the Long-term Impact of Military-relevant Brain Injury Consortium-Chronic Effects of Neurotrauma Consortium (LIMBIC-CENC) multicenter, observational study of Veterans and service members (SMs) with combat exposure.

Method: Baseline data of the participants passing all cognitive performance validity tests (n = 1,310) were used to conduct a cross-sectional analysis. Using multivariable regression models that adjusted for covariates, including age and estimated preexposure intellectual function, positive mTBI history …

People Are Curious About Immoral And Morally Ambiguous Others, Jordan Wylie, Ana Gantman

Publications and Research

Looking to the popularity of superheroes, true crime stories, and anti-heroic characters like Tony Soprano, we investigated whether moral extremity, especially moral badness, piques curiosity. Across five experiments (N = 2429), we examine moral curiosity, testing under what conditions the moral minds of others spark explanation-seeking behavior. In Experiment 1, we find that among the most widely watched Netflix shows in the US over a five-month period, the more immoral the protagonist, the more hours people spent watching. In Experiments 2a and 2b, we find that when given a choice to learn more about morally good, bad, ambiguous, or …

The Laser Interferometer Space Antenna (LISA) will be a transformative experiment for gravitational wave astronomy, and, as such, it will offer unique opportunities to address many key astrophysical questions in a completely novel way. The synergy with ground-based and space-born instruments in the electromagnetic domain, by enabling multi-messenger observations, will add further to the discovery potential of LISA. The next decade is crucial to prepare the astrophysical community for LISA’s first observations. This review outlines the extensive landscape of astrophysical theory, numerical simulations, and astronomical observations that are instrumental for modeling and interpreting the upcoming LISA datastream. To this aim, …

Mir-124-3p Target Genes Identify Globus Pallidus Role In Suicide Ideation Recovery In Borderline Personality Disorder, Macarena S Aloi, Guillermo F Poblete, John Oldham, Michelle A Patriquin, David A Nielsen, Thomas R Kosten, Ramiro Salas

Faculty, Staff and Students Publications

Borderline personality disorder (BPD) is characterized by patterns of unstable affect, unstable interpersonal relationships, and chronic suicidal tendencies. Research on the genetics, epigenetics, and brain function of BPD is lacking. MicroRNA-124-3p (miR-124-3p) was recently identified in a Genome-Wide Association Study as likely associated with BPD. Here, we identified the anatomical brain expression of genes likely modulated by miR-124-3p and compared morphometry in those brain regions in BPD inpatients vs. controls matched for psychiatric comorbidities. We isolated lists of targets likely modulated by miR-124-3p from TargetScan (v 8.0) by their preferentially conserved targeting (Aggregate PCT > 0.99, see Supplementary Table 1). …

The Wennberg Anthology, John E. Wennberg

Dartmouth Scholarship

In 1967, after finishing my postgraduate training at Johns Hopkins in internal medicine and epidemiology, I took a job at the University of Vermont in Burlington as Director of the Northern New England Regional Medical Program (RMP). The Vermont program was one of some fifty RMPs that blanketed the country as part of President Johnson’s Great Society program. The idea behind the RMP was that advances in biomedicine had so improved the outcomes of major killer diseases that it was critical to ensure that all Americans, not just those fortunate enough to live near an academic medical center, had access …

The accompanying essay, The Sons and Daughters of War, is a personal essay that details my experience with the trauma my father suffered in World War II and how such experience led to the writing of the book and essay.

Cannabis Use Disorder, Suicide Attempts, And Self-Harm Among Adolescents: A National Inpatient Study Across The United States, Adeolu Funso Oladunjoye, Elijah Li, Kammarauche Aneni, Edore Onigu-Otite

Faculty, Staff and Students Publications

Background: Suicide is among the top three causes of adolescent mortality. There is a scarcity of research examining cannabis use and suicidal behavior in adolescents.

Objectives: To determine the association between cannabis use disorder (CUD) and suicide attempt/self-harm in a hospitalized sample of adolescents.

Methods: We conducted a cross-sectional observation study using data from the Nationwide Inpatient Sample collected over four years from January 1, 2016, through December 31, 2019. We included adolescents aged 10-19 hospitalized during the above period (N = 807,105). The primary outcome was suicide attempt/self-harm and the main predictor was CUD. The International Classification of Diseases …

Network Effects Of Disruptive Traffic Events, Juan Medina, Xiaoyue Cathy Liu

TREC Final Reports

Current traffic management strategies are based on expected conditions caused by recurring congestion (e.g., by time of day, day of week), and can be very effective when provisions are also given for reasonable variations from such expectations. However, traffic variations due to non-recurrent events (e.g., crashes) can be much larger and difficult to predict, making also challenging efforts to identify, measure, and forecast their disruptive effects. This project explores a proactive approach to deploy a tool for managing non-recurrent congestion by identifying and quantifying the effects of disruptive traffic events at a microscopic level using a comprehensive set of data …

Unexpected Wins: Curating Comics And Teaching Manga From The Dark Horse Comics Collection, Elsa Loftis, Jon Holt

Library Faculty and Staff Publications and Presentations

A familiar staple of entertainment for a wide variety of readers, the comic book has not always held a regular place in the academic library. Concerning themselves with collecting more traditional expressions of scholarship, libraries have not historically dedicated much of their acquisitions budgets to this area. Therefore, the comic book or graphic novel was largely relegated to someone’s personal collection and would more likely be found on the shelves of a comic book store than the shelves of a university library.

Fast-forward to the present day, where library collections more commonly provide access to comic books, either in regular …

Social Enterprise Governance Post-Sox, Alina Ball

Faculty Scholarship

Social enterprises-nonprofit and for-profit businesses that use market-based strate­ gies to achieve social change for marginalized populations-demonstrate a new para­ digm for doing business in the United States. The Sarbanes-Oxley Act of 2002 ("SOX"), which transformed financial reporting and heightened internal controls for public com­ panies, has, perhaps unintentionally, also had an outsized influence on the development of social enterprise governance. The primary impact of SOX is found in the state-level auditing and reporting reforms imposed on large nonprofits. Moreover, "benefit re­ ports," the lynchpin of social enterprise state legislation, also mirror the SOX emphasis on transparency through third-party assessment. …

Rule 4 And Personal Jurisdiction, Scott Dodson

Faculty Scholarship

State-court personal jurisdiction is regulated intensely by the Fourteenth Amend- ment’s Due Process Clause, which the Court has famously used to tie state-court personal jurisdiction to state borders. Although the Fourteenth Amendment doesn’t apply to federal courts, the prevailing wisdom is that federal courts nevertheless are largely confined to the same personal-jurisdiction limits as state courts because of Rule 4(k), which provides that service “establishes personal jurisdiction” in federal court only upon specified conditions, including when the state courts would have personal jurisdiction. Some commentators have further argued that Rule 4(k) sets a limit on federal-court personal jurisdiction independent of …

Restorative Justice Diversion As A Structural Health Intervention In The Criminal Legal System The Criminal Legal System, Thalia Gonzalez

Faculty Scholarship

A new discourse at the intersection of criminal justice and public health is bringing to light how exposure to the ordinariness of racism in the criminal legal system—whether in policing practices or carceral settings—leads to extraordinary outcomes in health. Drawing on empirical evidence of the deleterious health effects of system involvement coupled with new threats posed by COVID-19, advocates and academics have increasingly called for race-conscious public health-driven reforms to carcerality in the United States. Recognizing the significance of health to carceral reform, the initiation of a health justice grounded lexicon in criminal justice has opened the doorway to new …

Misinformation And Covid-19, Dorit Rubenstein Reiss

Faculty Scholarship

The COVID-19 pandemic’s impact on our world cannot be overstated. One of its noticeable features was the prominence of misinformation generally, and anti-vaccine misinformation more specifically. This article provides a breakdown of the five major themes of antivaccine misinformation and the way they were used to create fear, uncertainty, and doubt about COVID- 19 vaccines. Long before the pandemic, anti-vaccine activists argued using a five-part playbook. They argued that (1) vaccine preventable diseases were not really dangerous, (2) vaccines were dangerous and ineffective, (3) there were alternative treatments that were better than (dangerous and ineffective) vaccines, (4) there was a …

Empowering Victims Of Grand Corruption: An Emerging Trend, Naomi Roht-Arriaza

Faculty Scholarship

Who is the victim of systemic corruption? The traditional answer in law is everyone and no one, or public administration itself. When state funds are misused or go missing, at the most the State is the victim. Therefore, only the State has standing to sue for, or receive restitution of, the stolen assets. But that long-held consensus is changing. Activists and lawyers have begun to argue that under systematic corruption it’s not just states, but individuals and communities as well as society as a whole that suffer losses and need to be both represented and repaired. Courts are beginning to …

A Trip To The Border: Legal History And Apa Originalism, Reuel E. Schiller

Faculty Scholarship

This article examines originalist interpretations of the Administrative Procedure Act (APA) from the perspective of a legal historian. After ex­ amining two pieces of originalist scholarship, it concludes that the histor­ ical record may not produce narratives of enough specificity or coherence to assist the originalist project. Nonetheless, it highlights three under-examined subjects of historical inquiry that have the most potential to aid APA originalists: the nature of administrative procedure during the first three decades of the twentieth century when the modem "appellate model" of judicial review emerged; the actual practice of ad­ ministrative law during the New Deal, both …

Suing Spacs, Emily Strauss

Faculty Scholarship

In 2020, the financial world became transfixed by a massive increase in the number of firms going public through special purpose acquisition company (“SPAC”) transactions. A SPAC is a publicly traded company formed solely for the purpose of raising money from investors and choosing a merger partner, thereby bringing the target company public. SPAC shareholders vote on the proposed transaction, but also have the option to redeem their shares for the price paid plus interest prior to the merger. SPACs have always been controversial; they make risky ventures available to unsophisticated investors, may involve acute conflicts of interest, and do …

Rewarding Failure With Patents, Robin Feldman

Faculty Scholarship

It is axiomatic that patents promote success. And yet, a contrary notion—that the patent incentive for medicine should be sufficient to compensate for the losses incurred when other research fails—is quietly permeating modern court decisions, commentary, and Congressional discussions, coloring debates relating to pricing and regulation of medicine. The conceptualization is moving forward unchallenged, as if failure compensation follows logically from the innovation incentives built into the patent construct. As this Article demonstrates, however, the notion is antithetical to patent law, putting modern conceptualizations on a collision course with the history and theory of patents reaching back to this nation’s …

Rights Violations As Punishment, Kate Weisburd

Faculty Scholarship

Is punishment generally exempt from the Constitution? That is, can the deprivation of basic constitutional rights—such as the rights to marry, bear children, worship, consult a lawyer, and protest—be imposed as direct punishment for a crime and in lieu of prison, so long as such intrusions are not “cruel and unusual” under the Eighth Amendment? On one hand, such state intrusion on fundamental rights would seem unconstitutional. On the other hand, such intrusions are often less harsh than the restriction of rights inherent in prison. If a judge can sentence someone to life in prison, how can a judge not …

Effects Of Landscape Configuration Metrics On American Barn Owl Nest Box Occupancy And Hunting, Samantha D. Chavez

Cal Poly Humboldt theses and projects

Harnessing ecosystem services, broadly defined as the benefits nature gives to people, is one approach to minimize the widespread negative impacts of agriculture on wildlife and biodiversity conservation. Conservation biological control is one such service that aims to use natural enemies to reduce crops losses from pests without the use of harmful pesticides, including rodenticides. In Napa Valley, California, human-made nest boxes are deployed on wine grape vineyards to attract barn owls (Tyto furcata) that depredate and remove thousands of rodent pests throughout the nesting season. However, the provisioning of this ecosystem service depends on whether a box …

The Impact Of Whole Fruits High In Anthocyanins On Blood Lipids In Middle-Aged Women, Denise N. Leininger

Cal Poly Humboldt theses and projects

Cardiometabolic Diseases (CMDs) are the leading cause of morbidity and mortality among women. During the menopause transition, drops in estrogen play a favorable role in the excess accumulation of Intraabdominal Fat (IAF), altering blood lipid metabolism and inducing inflammatory responses in CMDs attributed to dyslipidemia. This systematic review and meta-analysis examined current research on the effects of whole fruits high in anthocyanins on blood lipid metabolism in women at risk for CMDs. This meta-analysis included 15 studies using the PRISMA 2020 guidelines. Overall, effect sizes were not significant when exploring blood lipid marker outcomes High-Density Lipoprotein (HDL), Low-Density Lipoprotein (LDL), …

Because of this I noticed a need to these students who are not going to college. I found another high school that is currently operating an internal Work-Based Learning program. A WBL program is set up for students to go to during the last two periods of the day and shadow a tradesperson on the job. This gives …

The Interaction Of Treadmill Type And Incline Slope On Biomechanics And Muscle Activation During Human Locomotion, Rohit Kundu

Cal Poly Humboldt theses and projects

Treadmills are widely used in biomechanical research. However, variations in treadmill design and running surfaces may affect biomechanical variables such as muscle activation and impact acceleration. In addition, incline walking on treadmills leads to changes in the pattern of muscle activation, particularly at steeper inclines. Despite extensive research on the effects of running surfaces and inclines on biomechanical variables (gait, muscle activation, impact force), the impact of varying treadmill manufacturers on biomechanical variables at high inclines remains unclear. Purpose: To determine whether the type of treadmill deck influences surface electromyography (EMG) patterns and impact accelerations at high incline (20%) walking …

A Test Of Subjective Versus Objective Language Proficiency: An Investigation Of Age Of Acquisition And Exposure In Multilinguals, Anastina B. Steiber

This research used the BEST dataset gathered in 2017 by de Bruin and colleagues, which contains information gathered from 650 multilingual participants (435 female, Mage = 25.02) from the Basque Country at the Basque Center on Cognition, Brain and Language (BCBL). Multilingual individuals may have different levels of proficiency in each language they speak, and there are various factors that can influence proficiency. Such factors include the age at which they begin learning a language and how much exposure they have to the language. Proficiency can be assessed both subjectively (personal perception of proficiency) and objectively (observed and/or measured …

Factors Contributing To Legacy Hardwood Mortality Following Prescribed Fire, Heather D. Rickard

Cal Poly Humboldt theses and projects

Interruption of Indigenous stewardship has resulted in hardwood decline along what is now known as the middle Klamath River in northern California related to adverse effects to Tribal food sovereignty and community wellbeing. The survivors of a “legacy” of Indigenous stewardship are highly valued by the Karuk and neighboring Tribes for a myriad of culturally beneficial ecological associations and sources of traditional staple foods. Prescribed fire, following a century of fire exclusion, has resulted in unanticipated mortality of legacy tanoak (Notholithocarpus densiflorus), California black oak (Quercus kelloggii), and madrone (Arbutus menziesii), warranting further investigation. …

Extremism In America: Explaining Political Extremism Using Uncertainty-Identity Theory, Natasha A. La Vogue

Cal Poly Humboldt theses and projects

Navigating a post-pandemic society, climate-change, political conflict and international wars have become part of most people’s daily existence. These crises are sources of societal and personal uncertainty. An effective method of uncertainty reduction comes from people’s entrenched group memberships (e.g. nation, political party). Unfortunately, groups with extreme norms and ideologies provide rigid structures that aid in uncertainty reduction. From white nationalists to anti-fascists, the political arena is tumultuous to the point of explosion. These eruptions can be violent, even deadly, and are becoming too familiar and recognizable. Extremism poses both international and domestic threats. There is no nation or society …

A Cladoxylopsid With Complex Vascular Architecture From The Early Devonian Battery Point Formation (Québec, Canada), Jessica Chu

Cal Poly Humboldt theses and projects

Cladoxylopsids are seed-free plants that formed the world’s earliest forests and gave rise to horsetails (sphenopsids), but their evolutionary origins are poorly understood. Here, I describe a new Early Devonian cladoxylopsid from the Emsian (400-395 Ma) Battery Point Formation (Québec, Canada). The structural features of this plant indicate taxonomic affinity to cladoxylalean cladoxylopsids and its phylogenetic position supports placement in genus Cladoxylon (the proposed name, Cladoxylon kespekianum sp. nov., to be formalized by peer-reviewed publication). Specimens of this plant are permineralized in calcium carbonate and were studied using the acetate peel technique with light and electron microscopy. Cladoxylon kespekianum is …
