Trouble’S Bruen: The Lower Courts Respond, Brannon P. Denning, Glenn H. Reynolds

Minnesota Law Review Vols. 106:2 onward (2021-present)

New York State Rifle & Pistol Ass'n v. Bruen revolutionized the understanding of how Second Amendment cases are to be adjudicated. Rejecting the tiered-scrutiny analysis around which the lower courts had coalesced since the 2008 Heller decision, the Court instructed courts to look to history and tradition after it was determined that state or federal regulations limited activities that fell within the protections afforded by the Second Amendment's text. Justice Thomas's opinion, however, left open significant questions about how the history-and-tradition method is to operate in practice. The Court recently held oral arguments in United States v. Rahimi, in which …

Bridge The Gap: Using Advocacy To Bridge The Gender Wage Gap In Sports - A Comparative Analysis Of Venus Williams And The Us Women’S National Team, William E. Mitchell

Student Theses and Dissertations

For decades sports and activism have been synonymous. Many remember Jesse Owens and Tommie Smith’s Olympic protests, Mohammed Ali’s anti-war protest and Collin Kaepernick kneeling to bring attention to racial injustices. More recently many joined in celebration and applauded when the US Women’s National Team secured equal pay. However, many women in sports remain invisible. Activism is a viable form of seeking change, but can the route taken by Venus Williams work in team sports? This project will seek to examine if activism is a viable change agent in sports especially in closing the gender pay gap. While several female …

Application Of Methods To Population-Based Surveys To Reduce Bias In Estimates Of Sars-Cov-2 Infection Burden In The Population, Saba Qasmieh

Dissertations and Theses

BACKGROUND: Population-based surveys designed to randomly sample the population can be a critical and complementary tool to traditional surveillance approaches. Probability-based surveys enable the measurement of SARS-CoV-2 testing and outcomes that avoid issues around self-selection into testing, making them an effective approach to address ascertainment bias in passive surveillance. For surveys to be a useful and reliable surveillance tool for understanding the burden and distribution of SARS-CoV-2 infection, they need to capture prevalence estimates that are both valid and reliable to be optimally informative for public health measures. The dissertation was undertaken to address three main gaps that have implications …

A Psychological Evaluation Method Incorporating Noisy Label Correction Mechanism, Zhigang Jin, Renjun Su, Yuhong Liu, Chenxu Duan

Computer Science and Engineering

Using machine learning and deep learning methods to analyze text data from social media can effectively explore hidden emotional tendencies and evaluate the psychological state of social media account owners. However, the label noise caused by mislabeling may significantly influence the training and prediction results of traditional supervised models. To resolve this problem, this paper proposes a psychological evaluation method that incorporates a noisy label correction mechanism and designs an evaluation framework that consists of a primary classification model and a noisy label correction mechanism. Firstly, the social media text data are transformed into heterogeneous text graphs, and a classification …

Do Cognitive Resources Matter For Eudaimonia? The Role Of Inhibitory Control In Psychological Well-Being, Wei Xing Toh, Hwajin Yang

Research Collection School of Social Sciences

Although past work has investigated the psychosocial and biological correlates of psychological well-being (PWB), little is known regarding the cognitive underpinnings of PWB. Given that prior research has predominantly relied on indices of general cognitive abilities and PWB, we examined the relations between Ryff’s (1989) six-factor model of PWB and inhibitory control (i.e. the ability to actively maintain pertinent goals by resisting interference from irrelevant information or prepotent responses). Using structural equation modelling (N = 170), based on three inhibition measures and six facets of PWB, we found that better inhibitory control was associated with greater personal growth, when cognitive, …

Producers’ Transition To Alternative Food Practices In Rural China: Social Mobilization And Cultural Reconstruction In The Formation Of Alternative Economies, Qian Forrest Zhang

Research Collection School of Social Sciences

The shift from the conventional agri-food system to alternative practices is a challenging transition for agricultural producers, yet surprisingly under-studied. Little research has examined the social and cultural processes in rural communities that mobilize producers and construct and sustain producer-driven alternative food networks (AFNs). For AFNs to go beyond just offering “alternative foods” or “alternative networks” and to be constructed as “alternative economies”, this transformation in the producer community is indispensable. This paper presents a case study of a rural cooperative in Shanxi, China. The discontent with both productivist agriculture and the social decay in communities motivated a group of …

Subjective Socioeconomic Status Moderates How Resting Heart Rate Variability Predicts Pain Response, Jacinth Jia Xin Tan, Chin Hong Tan, Michael W. Kraus

Research Collection School of Social Sciences

Higher resting heart rate variability (HRV)—an index of more flexible response to environmental stressors, including noxious stimuli—has been linked to reduced perception of experimentally induced pain. However, as stress responses are adapted to one’s chronic environments, we propose that chronic exposure to threats captured by one’s subjective socioeconomic status (SSS) may shape different adaptations that produce distinct pain responses linked to higher resting HRV. Specifically, lower SSS individuals with more threat exposures may prioritize threat detection by upregulating sensitivity to stressors, such as acute pain. Therefore, higher HRV would predict greater perceived acute pain among lower SSS individuals. In contrast, …

Eosinophilic Jejunitis Presenting As Intractable Vomiting, Persistent Leukocytosis, And Ascites In A Young Adult Patient, Dawood Tahir, Shravya Ginnaram, Erkanda Ikonomi

Abington Jefferson Health Papers

Eosinophilic enteritis (EoN) poses a distinctive challenge, affecting individuals with various clinical presentations depending on the layer and extent of the bowel wall. We present a case of a 19-year-old female with abdominal pain, vomiting, and loose stools for 1 month. Labs were significant for persistent leukocytosis with peripheral eosinophilia. A computed tomography of the abdomen/pelvis demonstrated moderate abdominal ascites and moderately diffuse mucosal thickening of jejunal loops. A diagnostic paracentesis unveiled low serum ascites albumin gradient and 92% eosinophils. Push enteroscopy resulted in no significant biopsy findings, though a laparoscopic full-thickness jejunal biopsy exhibited increased eosinophils in the bowel …

Memoriam, Mira Helena Darham

Dartmouth College Master’s Theses

The chasm between past and present is a constant reminder of the perilous journey one takes through the fissures of memory. While on this expedition the forms surrounding you, the memories themselves, are a constantly changing landscape that make navigation a difficult and dangerous task. Is a memory a recall or a remembrance, truth, or construction? Are all memories as they happened or are we the “rememberer,” the architect of their composition? This dilemma has been the impetus of my academic pursuits and creative endeavors. For Memoriam I have chosen an event in my past, a wildfire, as the catalyst …

Strengthening U.S. Jail Systems’ Response To Infectious Diseases: An Evaluation Of The Covid-19 Pandemic, Erinn Bacchus

Dissertations and Theses

Jails across the United States were struck with increased infections and deaths during the COVID-19 pandemic. Studies have shown the structural make up of jails, lack of preparedness plans, and overcrowding contributed to health risks and poor health outcomes both inside jails and local communities. Yet little research has been dedicated to strengthening jail responses to infectious disease outbreaks spanning prevention measures, data collection, and reentry planning. Gaps include information on the (1) myriad infectious disease mitigation strategies used in jails and adherence to CDC prevention guidelines, (2) development of a standardized epidemiologic surveillance system, and (3) experiences working at …

It's Disco, Baby: Queer Possibilities And Conservative Outrage, Lottie Bromham

University Honors Theses

From 1974 to 1979, disco music was a cultural phenomenon, gracing radio airways and dance clubs across the United States. Just as disco music reached peak popularity, growing disapproval from rock fans and other Americans who saw the genre and scene as overly lavish, too effeminate, and too racially inclusive, forced disco out of American mainstream favor. This paper proposes a viewpoint that contextualizes disco culture as integral to the lives of queer people in New York City, analyzes the prejudices that accompanied the anti-disco movement, and situates the mainstream death of disco as an early cultural consequence of America's …

Talking Yourself Up: Multimodal Conversation Analysis Of Status In An Improvised Setting, Aubrey Lewarne

University Honors Theses

A single-case analysis looked at two individuals performing a scripted exercise during an Applied Improvisational workshop. The analysis examined how performers modify their linguistic and embodied actions in order to perform an assigned status role. The analysis was undertaken to better understand how social status can be constructed in everyday talk-in-interaction. I first outlined the three major theoretical frames that are relevant to the analysis: Applied Improvisation as a pedagogical approach, the use of Conversation Analysis (CA) for the analysis of language in educational contexts, and the concept of status from a sociological perspective. I then present a single-case study, …

We're Here To Stay: Nonviolence And The Disability Rights Movement, Sky Mcleod

University Honors Theses

Nonviolent resistance is an effective tool for enacting large scale change including the advancement of civil rights. Disabled Americans have often used nonviolent protest and civil resistance to this aim. Despite this rich history of activism, the history of the Disability Rights Movement has largely been missing from scholarship on nonviolent resistance. Similarly, historical accounts in Disability Studies provide a fragmented perspective on the use of nonviolent resistance by Disabled people. This thesis delves into this under-appreciated history. From the League of the Physically Handicapped in the 1930s to Trump’s inauguration in 2016, this paper traces the progress of the …

"Crush The Monster": Homosexuality And Moral Panic In 1950s Idaho, Ian Hadrick

University Honors Theses

On October 31, 1955, three men were arrested and accused of performing homosexual acts in the quiet, suburban community of Boise, Idaho. The arrests set off a sweeping investigation of Boise's "widespread homosexual underground" that made national news and resulted in more than one thousand police interrogations and the conviction of fifteen homosexual Boiseans. Though Boise's moral panic and the ensuing investigation are among the largest of the sex panics of the 1950s, the city's 1955 homosexuality scandal has attracted relatively little scholarly attention. An in-depth analysis of the social, economic, and political forces that combined to produce hysteria in …

At The Intersection Of Domestic Violence And Mass Shootings: A Qualitative Analysis Of The Relationship Between Ipv And Gun Violence, Troy Bleau

University Honors Theses

The intersectional study of domestic violence and mass shootings has only recently been the subject of inquiry within the psychology field. Within the past ten years research has been developed to examine the relationship between these two epidemics. What authors have found is that DV does play a role in shooting perpetration. This study aimed to identify domestic violence as a risk factor to predict, and subsequently intervene before future instances of shootings. 112 shootings were analyzed between the years of 2020 and 2023--they were then categorized as DV-related, non-DV related, and/or History of DV. The tested hypothesis was that …

Green Gold: The Akkoub’S Settler Ecologies, Irus Braverman

Journal Articles

The akkoub (Gundelia tournefortii) is a thistle-like plant so precious in Palestinian cuisine that it is often referred to as “green gold.” The risks, as well as the mystique, surrounding the akkoub have only intensified since the state of Israel designated this plant as protected under the Nature and Parks Protection Act. The story of the akkoub as depicted in this article illustrates the three tenets of “settler ecologies”: the regime of environmental protections enacted by the settler state that furthers its domination of the natural landscape and its dispossession of local and Indigenous communities. The first and …

Repeated Stimulation Of Feeding Mechanoafferents In Aplysia Generates Responses Consistent With The Release Of Food, Hillel J. Chiel

Faculty Scholarship

How does repeated stimulation of mechanoafferents affect feeding motor neurons? Monosynaptic connections from a mechanoafferent population in the Aplysia buccal ganglia to five motor followers with different functions were examined during repeated stimulus trains. The mechanoafferents produced both fast and slow synaptic outputs, which could be excitatory or inhibitory. In contrast, other Aplysia mechanoafferents produce only fast excitation on their followers. In addition, patterns of synaptic connections were different to the different motor followers. Some followers received both fast excitation and fast inhibition, whereas others received exclusively fast excitation. All followers showed strong decreases in fast postsynaptic potential (PSP) amplitude …
