These online interactions have begun to be investigated as accessible methods through which adolescents can connect with others and maintain healthy relationships. Furthermore, digital social networks may be most critical for youth from isolated communities, including those from rural areas. …

Religious Upheaval In A South Dakota Mennonite Community, 1874-1940, Ryan Mews

Dissertations and Theses

In 1874, multiple colonies of German-Russian Mennonites and Hutterites entered the Dakota Territory to settle into tightknit religious communities. These Anabaptists sought to escape religious persecution and assimilation in Russia but found themselves influenced by American religious groups. Their history of isolationism caused these groups to draw lines between their congregations that kept them small but allowed them to interact with new ideas in different ways, but caused them to redefine their German Mennonite identity. One such influence erupted from the Presbyterian Church called fundamentalism that encouraged evangelical works in America and sought to combat modernism in religious institutions. In …

Mental Health In College Students: Efficacy Of A Telehealth-Delivered Occupational Therapy Program, Amy Marie Nelson

Dissertations and Theses

The number of college students in the United States struggling with mental health issues has increased tremendously over the past decade. Specifically, undergraduate students report stress and anxiety as significant inhibitors to academic performance. Colleges are investing resources to combat this problem, but increased counseling services are insufficient. Novel approaches beyond traditional college counseling services are recommended. Occupational therapy, not traditionally offered on most college campuses, may be one solution. A few occupational therapy programs exist on college campuses, but there is limited evidence of their efficacy, and most lack solid theoretical underpinnings. More evidence is needed on the effectiveness …

Designing Fluorescent Moscs For Potential Applications In Illicit Drugs Detection, Robyn Nicole Cook

Dissertations and Theses

Illicit and hazardous substances pose a serious effect on the human body which can create longer-term issues on the mental and physical health which potentially lead to fatalities. Current methods for detecting illicit substances include analytical techniques like mass spectrometry (MS) and gas/liquid chromatography (GC/LC) which are known for accuracy and sensitivity. However, these instruments are bulky, costly, time-consuming, and require highly trained personnel. An alternative approach to overcoming these limitations is to employ nanostructured molecule-based chemical sensing technologies that are user-friendly, portable, and cost-effective with the sensitivity for detecting illicit substances. One such candidate is metal-organic super-containers (MOSCs), which …

Exploring The Links Between Unknowns, Uncertainty And Epistemological Understanding In A More Authentic Form Of School Science Investigation, Matthew Wharf

Other Faculty of Arts, Humanities and Business Theses

This research explored the role a more ‘authentic’ science investigation had on the epistemological understanding of secondary school students. It reviewed the understanding of what is taught within the science curriculum in terms of epistemology and the Nature of Science (NOS) and what may be considered a more authentic activity that more closely aligns with the qualities of professional science, where new knowledge is being formed as compared to what could be seen as conventional science investigations, the repetition of classic experiments. Lessons of 3 different classes, at different schools and in different years were used. An investigation lesson from …

The Assessment-Related Logics Of Practice At A South West Multi-Academy Trust, Samuel Gordon Morahan

Plymouth Institute of Education Theses

Over the last 40 years there have been widescale changes to the British education system. Through the process of neoliberalisation, education has become a commodity to be bought and sold with an ever-increasing emphasis on performativity and its related measures. Within this educational market, alternative provision settings provide commissioning schools with opportunities to purchase placements and packages for pupils, who for a variety of reasons, are unable to engage in mainstream education. Alternative provision settings must evidence value for money to these schools, whilst meeting statutory inspection requirements. Assessment practices and the numerical data they generate are central within this …

In the largest survey to date on Catholic school identity in athletics (49 U.S. States, n = 2273), administrators, counselors, and teachers responded to a survey about the perceived value of interscholastic athletics, school support of athletics, the contribution of coaches to school mission, Catholic identity in athletics, and the importance of the school’s athletic director and coaches to have a mission orientation. The results of the study indicate that administrators, counselors, and teachers have positive perceptions of Catholic high school athletics. Teacher perceptions differed more than administrators and counselors based on their age, gender, and religion. At least one …

Faith And Stem Education: A Path To Mutual Elevation In Catholic Schools, Michael Szopiak, Matthew Kloser

Journal of Catholic Education

Amidst increasing religious disaffiliation, often due to a perceived tension between faith and the STEM disciplines, Catholic schools provide critical opportunities for young people to recognize how these domains can be mutually elevating. The field, however, lacks guidance as to how this integration should occur in practice. This conceptual paper first provides an overarching framework for how aspects of the Catholic tradition, like Scripture and the Catholic social tradition, can shape traditional educational domains of STEM teaching and learning. Secondly, we provide a heuristic of three criteria for deeply engaging students at the interface of the Catholic faith and the …

Increasing Parent Faith Engagement At A Parish School, Grace Mazza Urbanski

Journal of Catholic Education

Increasing faith engagement among Catholic school shareholders is a priority for school leaders. Catholic school communities can learn from this year-long project with a parish school.

Using critical research methodology with qualitative data collection, we studied five teachers of color who engaged in weekly affinity group meetings, which were structured as Freirian culture circles and ran over a period of five months. Using a Catholic, critical framework on teacher education, we analyzed the data (culture circle recordings, written reflections, baseline and comparative interviews, along with classroom observations and debriefs) to examine how teachers’ participation impacted their …

Augustinian Composition Pedagogy And The Catholic Liberal Arts In The Time Of Generative Ai, Gavin F. Hurley

Journal of Catholic Education

This article proposes a theoretical basis of Augustinian composition pedagogy by tracing the symbiotic relationship between writing and knowing found within St. Augustine’s Letters, The Trinity, Soliloquies, and Confessions and connecting them to modern writing-to-learn composition pedagogies. Given today’s trying times of generative AI, this article argues that Catholic schools revitalize the writing arts in a manner proposed by Augustine—that is, to enrich inward contemplation and outward love for others. In embracing such philosophy of writing and applying it across the disciplines, Catholic schools can enrich their distinctively Catholic liberal arts mission—and ward off dangers found in …

Faculty, Staff and Student Publications

Utilizing electronic health records (EHR) for machine learning-driven clinical research has great potential to enhance outcome predictions and treatment personalization. Nonetheless, due to privacy and security concerns, the secondary use of EHR data is regulated, constraining researchers’ access to EHR data. Generating synthetic EHR data with deep learning methods is a viable and promising approach to mitigate privacy concerns, offering not only a supplementary resource for downstream applications but also sidestepping the privacy risks associated with real patient data. While prior efforts have concentrated on EHR data synthesis, significant challenges persist: addressing the heterogeneity of features including temporal and non-temporal …

Federated Node Classification Over Distributed Ego-Networks With Secure Contrastive Embedding Sharing, Han Xie, Li Xiong, Carl Yang

Faculty, Staff and Student Publications

Federated learning on graphs (a.k.a., federated graph learning- FGL) has recently received increasing attention due to its capacity to enable collaborative learning over distributed graph datasets without compromising local clients' data privacy. In previous works, clients of FGL typically represent institutes or organizations that possess sets of entire graphs (e.g., molecule graphs in biochemical research) or parts of a larger graph (e.g., sub-user networks of e-commerce platforms). However, another natural paradigm exists where clients act as remote devices retaining the graph structures of local neighborhoods centered around the device owners (i.e., ego-networks), which can be modeled for specific graph applications …

A Brief But Comprehensive Three-Item Social Connectedness Screener For Use In Social Risk Assessment Tools, Nancy P Gordon, Matthiew C Stiefel

Faculty, Staff and Student Publications

BACKGROUND: The 2014 IOM report "Capturing Social and Behavioral Domains and Measures in Electronic Health Records" described three subdomains of social relationships that affect patient health and well-being. However, most social risk screeners currently assess only one subdomain, frequency of social connections. We are proposing a three-item Brief Social Connectedness (SC) screener that additionally assesses risks in social/emotional support and loneliness/social isolation subdomains.

METHODS: For this cross-sectional study, we used data from a 2021 Kaiser Permanente Northern California (KPNC) social risk survey for 2244 members ages 35-85 years. The survey included three validated questions that covered the SC subdomains (frequencies …

On The Relative Conservativeness Of Bayesian Logistic Regression Method In Oncology Dose-Finding Studies, Cheng-Han Yang, Guanghui Cheng, Ruitao Lin

Faculty, Staff and Student Publications

The Bayesian logistic regression method (BLRM) is a widely adopted and flexible design for finding the maximum tolerated dose in oncology phase I studies. However, the BLRM design has been criticized in the literature for being overly conservative due to the use of the overdose control rule. Recently, a discussion paper titled "Improving the performance of Bayesian logistic regression model with overall control in oncology dose-finding studies" in Statistics in Medicine has proposed an overall control rule to address the "excessive conservativeness" of the standard BLRM design. In this short communication, we discuss the relative conservativeness of the standard BLRM …
