Secondary School Students' Engagement In Learning Activities: Validation Of A Short Scale, Feliciano Henriques Veiga, Zi Yang Wong, Johnmarshall Reeve, Shane Jimerson, Antonio Leite, Joan Perales, Sonia Valente, Isabel Martinez

Research Collection School of Social Sciences

Student engagement is a multidimensional construct strongly associated with learning outcomes and academic success. However, its measurement remains challenging, as existing instruments often conflate engagement in learning activities with engagement in the school community. In addition, brief measures are scarce despite their increasing value, and most available instruments do not incorporate agentic engagement. Assessing student engagement in learning activities is, therefore, crucial for monitoring academic progress, identifying students at risk of dropping out, and predicting academic success. This study aimed to validate the 12-item Secondary School Student Engagement in Learning Activities: Short Scale, adapted from a higher education measure, which …

Towards Enabling Environmental Social Enterprises: Two Case Studies From Egypt, Rana Emad Kamaly

Theses and Dissertations

Social enterprises (SEs) and environmental social enterprises (ESEs) are emerging as promising potential players in addressing global and Egyptian social and environmental challenges. Operating as a hybrid model of financial sustainability and environmental and social impact, ESEs operate through innovative business models to address community issues, waste management, and resource scarcity through financial sustainability. However, there is a lack of research on ESEs operations, challenges, and the enabling factors that can support their growth and impact. This study explores the enabling factors and challenges affecting ESEs in Egypt through qualitative research, analyzing two case studies from Egypt by conducting semi-structured …

Is History Precedent?, Allison Orr Larsen

Faculty Publications

It has been just over three years since the Supreme Court instructed lower courts to evaluate Second Amendment challenges by examining history and tradition. And it is no secret that the courts have struggled. This Article tackles a phenomenon that is born of that struggle. Overwhelmed by the task of evaluating historical claims, lower courts instead are turning to other judges as authorities on history. They are using what I call in this Article “historical precedents”—meaning language about history from an older decision that the subsequent judge then treats as authority, not as part of a legal rule but for …

Reconceiving Safety Regulation For Ai And Ml Medical Software, Barbara J. Evans, Eric S. Rosenthal, Azra Bihorac

Vanderbilt Journal of Entertainment & Technology Law

This article explores the challenges of regulating AI and ML clinical decision support tools intended to assist trained health care professionals in delivering clinical care. Two old, twentieth-century regulatory models have dominated discussions of medical AI policy since 2013. Thinking inside these old regulatory boxes has not produced effective regulatory solutions to address the novel risks AI poses in clinical care. The first regulatory box treats software as a medical device, which tasks medical device regulators with making software safe but neglects the crucial roles physicians, nurses, administrators, medical practice regulators, and other health oversight bodies must also play to …

Leadership Styles And Their Impact On Employee Engagement, Commitment, And Satisfaction In Non-Profit And For-Profit Organizations, Laure-Ann Swaby

JWU Dissertations & Theses

As organizations face challenges in sustaining retention and development, they must analyze and implement strategies to strengthen their workforce (Hassanein & Özgit, 2022). Employees are a company's greatest asset; without them, production would halt, as their knowledge, skills, and abilities drive organizational performance and operations (Chunhui et al., 2004; Gallup, 2023). Sturm and Vera (2011) showed that employees tend to be less committed when factors such as desired leadership styles, engagement, and job satisfaction are negative within an organization. Over the past decade, turnover has increased significantly, imposing financial challenges to organizations across both the non-profit and for-profit sectors (McCrory …

Understanding how rare genetic variants influence complex traits remains a major challenge, particularly when these variants lie in noncoding regions of the genome. The effects of variants within candidate cis-regulatory elements (cCREs) often depend on the cell type, making interpretation difficult. Here we introduce cellSTAAR, which integrates whole-genome sequencing data with single-cell assay for transposase-accessible chromatin using sequencing data to capture variability in chromatin accessibility across cell types via the construction of cell-type-specific functional annotations and regulatory elements. To reflect the uncertainty in cCRE-gene linking, cellSTAAR uses a comprehensive strategy to link cCREs to their target genes. We applied cellSTAAR …

Engineering Enac Constructs To Examine Pip2 And Ubiquitin Competition On Enac Regulation And Stability, Lacie Johnson

Chemistry & Biochemistry Undergraduate Honors Theses

The epithelial sodium channel (ENaC) plays a critical role in sodium homeostasis, fluid balance, and blood pressure regulation. ENaC activity is tightly controlled by post-translational mechanisms, including ubiquitination-mediated degradation and phosphatidylinositol 4,5-bisphosphate (PIP2) dependent channel activation. PIP2 is a phospholipid necessary to facilitate the maximal channel opening. Previous studies suggest that intracellular PIP2 binding sites are located in proximity to ubiquitination sites on ENaC subunits, raising the possibility of PIP2 binding to influence channel stability and function. This thesis aimed to engineer and validate molecular tools capable of examining the interplay between PIP2 binding and ubiquitination in ENaC regulation. A …

Controlled Antibiotic Release From Emulsion-Loaded Alginate And Fibrin Hydrogels Using Ultrasound, Ziba Ghareh Nazi Fam, Asia Winslow, Mario Fabiilli, Sam Varghese, Brian Oeffinger, Flemming Forsberg, Noreen Hickok, Lauren Delaney

Department of Radiology Faculty Papers

Postoperative infections remain a major complication after spinal fusion surgery, often caused by biofilm-forming bacteria that resist short-term antibiotic prophylaxis. Vancomycin (VAN) is sometimes delivered locally during surgery; however, levels diminish rapidly, leaving patients vulnerable to late-onset infections. We developed a composite hydrogel integrating perfluorohexane-based emulsions within alginate or fibrin matrices to enable both sustained and ultrasound-triggered VAN release. Water-in-oil-in-water emulsions were prepared using fluorosurfactant-stabilized perfluorohexane as the volatile oil phase, then embedded in hydrogels and exposed to ultrasound (2.5 MHz, 5.5 MPa peak negative pressure) to initiate acoustic droplet vaporization for triggered release. Drug release was quantified spectrophotometrically and …
