Background: Functional seizures (FS) are paroxysmal episodes that phenotypically resemble epileptic seizures but are not associated with brain epileptiform discharges; they are also known as psychogenic nonepileptic seizures. The exact etiology and pathophysiology of FS is unknown; however, trauma and stress-related disorders are known risk factors.

Methods: We used a validated algorithm applied to electronic health records to identify individuals with FS in 6 international biobanks and hospital sites. We conducted a multisite FS genome-wide association study (GWAS) meta-analysis, including 10,910 FS cases (9040 predicted European ancestry [EA] and 1870 predicted African ancestry [AA]) and 664,500 (561,150 EA and 103,350 …

Optimisation Of Sampling For A New Skin Microbiome Assay Pilot Study, Anita Smith

Theses

Recent interest in the diverse ecosystem of bacteria, fungi and viruses that make up the skin microbiome has led to numerous studies investigating the microbiome in healthy skin and in dermatological diseases. An imbalance of the normal skin microbial flora can cause some skin diseases, and current culture techniques are often unable to detect a microorganism to further our understanding of the clinical–microbiological correlates of disease and dysbiosis. Atopic dermatitis and rosacea are presentations that General practitioners (GPs) often manage that may have an infective or microbiological component and can be challenging to treat. Further research using culture-independent techniques is …

Advancing Edge Intelligence: Strategies For Improving Machine Learning On Embedded Devices, Prakash Dhungana

Theses and Dissertations--Electrical and Computer Engineering

Artificial intelligence (AI) has demonstrated tremendous success in handling complex tasks across multiple domains, a leap largely attributed to complex deep neural network (DNN) architectures. However, the increasing demand for real-time processing, low latency, limited connectivity, and enhanced privacy necessitates edge intelligence, where computation is performed directly on resource-constrained embedded devices rather than relying on cloud infrastructures. While optimized TinyML techniques such as pruning, quantization, and neural architecture search (NAS) have made edge deployment feasible by significantly reducing computation and memory demands, achievable performance remains severely limited by hardware constraints. Furthermore, models deployed in highly dynamic real-world environments suffer from …

Age, Law, And Political Economy, Alexander Boni-Saenz

Articles

This Article examines the intersection of age, class, and the law. Its central claim is that age is an essential dimension for the analysis of law and political economy. There are two primary reasons why. First, age is embedded in a large body of legal rules that structure the labor market and address vulnerabilities associated with particular life stages. Child labor laws set minimum ages for entry into the workforce, while social welfare laws use age eligibility criteria to shape the material conditions for older adults. Second, age and its sibling concept, generation, indirectly shape economic and political relations by …

The Effect Of Social Buffering And Gender On Cortisol Response In Emerging Adults, Ashley G. Molchany

West Chester University Graduate Theses, Dissertations, and Final Projects

Abstract

Cortisol, the primary stress hormone in the body, is released in times of challenge, including challenges faced throughout the transition to college. The experience of acute stress can be assessed through cortisol measures. The present study involved a 60-minute lab assessment for first-year students to analyze their physiological response to stress. Previous research has illustrated factors which impact cortisol responses, two of which are social support and gender. In the current study, participants (n = 71) were assigned to work either by themselves (Student Alone Condition) or in a peer triad group (Peer Triad Condition). Additionally, participants identified …

Arts Enriched Head Start Preschool And School Readiness: Are Benefits Accentuated For Children Facing Greater Economic Hardship?, Isabella Capera

West Chester University Graduate Theses, Dissertations, and Final Projects

Children growing up in impoverished and low-income households face opportunity gaps that limit their school readiness (Blair & Raver, 2015). Head Start preschool, which serves families facing economic hardship, has been demonstrated to reduce these gaps and enhance school readiness. Further, multiple studies have suggested that arts enriched Head Start may offer particular benefits (e.g., Brown et al., 2010, 2018; Lobo & Winsler, 2008). Yet research to date is limited and has not examined whether the benefits of arts enriched preschool may be uniquely helpful for children facing the greatest economic risk. The present study examines growth in school readiness …

This broadening mission underscores the importance of staff within the higher education organizations’ mission-delivery functions. However, the execution of this work is hindered by staff attrition in positions primarily filled by women. The current literature on mentorship …

Rest My Case: Sleep Science Should Inform J.D. Program Structures And Licensure Examinations To Enhance Performance, Equity And Well-Being, Laura J. Mott, Paula J. Manning

Minnesota Journal of Law, Science & Technology

This Article critically examines the legal profession’s longstanding marginalization of sleep and circadian biology and argues that temporal structural norms embedded in legal education and licensure are at odds with established scientific evidence. Drawing on extensive and interdisciplinary research in neuroscience, chronobiology, cognitive psychology, and timekeeping, this Article explores how sleep deprivation and chronotype misalignment with institutional schedules impair attention, memory, emotional regulation, mental and physical health, and decision-making—capacities that are essential to competent, ethical, and sustainable legal practice. Despite robust scientific consensus that sleep quality, quantity, and timing have profound effects on performance and well-being, law schools and licensing …

Private Standards As Liability Shields: A Pro-Innovation Artificial Intelligence Regulatory Approach For States, Gary E. Marchant, Jordan Buckwald

Minnesota Journal of Law, Science & Technology

States face a dilemma. The federal government is not regulating artificial intelligence (AI), and is threatening states that regulate the technology with preemption and funding restrictions. Moreover, piecemeal state regulation with different substantive requirements risks impeding AI innovation and harming our national interest and security. And yet, AI creates a whole host of problems relating to accuracy, safety, security, bias, transparency, privacy, and autonomy that needs to be governed. This Article presents a solution to this dilemma that can protect against AI risks without harming innovation and the national interest. The proposal is for states to provide a liability shield …

Results: Tanzanians showed significantly smaller craniofacial measurements than Caucasians. Males had larger skeletal dimensions than females. Compared to West Africans, Tanzanians had generally higher values, with a few exceptions. Conclusion: Tanzanians display distinct craniofacial characteristics, differing from both Caucasians and West Africans. These findings support the need for population-specific cephalometric norms to guide accurate orthodontic diagnosis and treatment.

High Technology And The Developing State: The Arrival Of Supercomputers In India, Ramesh Subramanian

Journal of International Technology and Information Management

While India has made vast strides in information technology in the last few decades, its success is mainly attributed to its software, rather than its hardware sector. In fact, India’s attempts at developing computer hardware that can match international standards have largely been unsuccessful. A notable exception is its development of a series of supercomputers that match and exceed many international standards. This paper looks at an interesting period in India’s computing history – namely the 1980s and 1990s – focusing on its development of an indigenous supercomputer. During that period, supercomputers were thought to be the sole privy of …

Dataset: The Impact Of External Resource Use On The Validity Of Score Interpretation For A Biology Concept Assessment Administered Out-Of-Class, Tiffany J. Burgess, Crystal Uminski, Gia Alicea, Brian A. Couch

School of Biological Sciences: Faculty Publications

Instructors use concept assessments to gauge student knowledge and guide course improvement. Many instructors experience time and logistical constraints around administering these assessments in class. For this reason, administering concept assessments outside of class can help increase feasibility. While previous studies have cautioned that the use of external resources (e.g., internet, course notes, peers) in the out-of-class setting may inflate assessment scores, the extent to which undergraduate students access various resources when completing concept assessments is unknown. The current study uses two survey question formats to better understand whether students engage with external resources when taking a biology concept assessment …

Dataset: Participation Versus Points: Examining The Impact Of Grading Conditions On Student Resource Use During An Out-Of-Class Biology Concept Assessment, Tiffany J. Burgess, Crystal Uminski, Brian A. Couch

School of Biological Sciences: Faculty Publications

Instructors use concept assessments to collect diagnostic information regarding student learning and to inform decisions surrounding instructional interventions and course modifications. Administering concept assessments out-of-class helps preserve already limited instructional time, but instructors still must consider whether to apply a lower-stakes (i.e., participation) versus higher-stakes (i.e., correctness) grading scheme. An increase in stakes is likely to prompt additional effort, but it may also increase undesired behaviors and inadvertently prompt external resource use, such as students leveraging their notes, the internet, or their peers. In the present study, we compared student self-reported resource use on a biology concept assessment administered under …

Saudi Medical Journal

Objectives: To explore gender-related variations in sociodemographic factors, clinical presentations, and psychosocial characteristics among methamphetamine users in Saudi Arabia. Methods: A retrospective cross-sectional study was conducted using the electronic health records of 1,181 patients (91% male, 9% female) treated at multiple Erada Mental and Addiction Centers across Saudi Arabia (2020–2024). Data on sociodemographic characteristics, methamphetamine use patterns, psychiatric comorbidities, and psychosocial functioning were collected and analyzed using validated tools, including the Addiction Severity Index, Beck Depression and Anxiety Inventory, and Quality of Life Scale. Results: Female participants were younger than males (mean age 25.3 vs 28.5 years; p < 0.001) and initiated methamphetamine at a later age (21.4 vs 19.2 years; p < 0.001). Females had greater proportion of daily use (65.4% vs. 60%, p = 0.035) but consumed smaller amounts per day (1.5 vs. 1.8 g, p = 0.041). They also exhibited higher rates of psychiatric comorbidities, including depression (50% vs. 30.0%, p < 0.001) and anxiety (40% vs. 20%, p < 0.001), and reported more severe psychosocial impairments, including lower quality of life (54.8 vs. 62.4, p < 0.001), higher unemployment rates (59.8% vs. 30%, p < 0.001), and more family conflicts (65.4% vs. 50%, p < 0.001). In contrast, Legal issues were more common among males (40% vs. 29.9%, p = 0.002). Conclusions: Female methamphetamine users demonstrate greater vulnerability with earlier onset, more psychiatric comorbidities, and worse psychosocial outcomes. Targeted interventions are needed for female methamphetamine users in Saudi Arabia.
