A New Hybrid Approach For Magnetohydrodynamic Flow Over A Stretching Surface With Nanofluid, Ammar Al-Salih, Abdul-Sattar Jaber Al-Saif

Baghdad Science Journal

The current investigation focuses on developing a semi-analytical technique aimed at estimating the solutions of magnetohydrodynamics flow with Casson tri-hybrid nanofluid (TiO₂ - SiO₂ - Al₂O₃/blood) flowing over a stretchable surface along two-dimensional space. To solve the obtained nonlinear coupled differential equations in the problem formulation, the proposed semi-analytical approach makes use of the Shehu reduced differential transform Padé method (SRDTPM). Several physical parameters, such as slip effect, porosity, magnetic strength, and Casson number, were considered for examining the effect on momentum, while radiation parameter, heat generation/absorption, temperature-dependent heat sink/source term, and Biot number …

Parent Perspectives On Primary And Secondary Online Learning, Barbara Tanner Sandberg

Theses and Dissertations

Given the growth of K-12 online learning and the expanded responsibilities parents often assume in this learning context, the purpose of this dissertation is to understand parents' perspectives on K-12 online learning.

Crisis Severity In Sportswashing: Examining The Effects On Host Nations, Erika J. Schneider, Courtney D. Boman, Mutaz M.. Barnawi, Kenon A. Brown

Media Studies - All Scholarship

This study examines how the men’s 2022 FIFA World Cup in Qatar, marked by allegations of labor abuses, influenced U.S. viewers’ perceptions of the host nation through the lens of “sportswashing.” Utilizing a survey of self-identified U.S. viewers of the World Cup, the analysis examines how viewers’ personal involvement and recognition of human rights concerns influenced their perceptions of the crisis’s severity. Findings show that recognition of the problem, by viewers themselves, significantly increased perceptions of severity, while involvement with the issue of human rights did not have a direct effect on severity perceptions. Higher perceptions of severity, in turn, …

Classification Of Phishing Data Using Hybrid Mi-An Feature Selection Method, Damodar Patel, Amit Kumar Saxena, Wutiphol Sintunavarat, Abhishek Dubey

Baghdad Science Journal

Web phishing attacks have been continually evolving over the past few years, which has led customers to lose their trust in online services and e-commerce. To identify phishing data, a variety of methods and systems based on a blacklist of phishing websites are used. However, the rapid development of technology has given rise to increasingly complex techniques for creating user-attracting websites. Therefore, current blacklist-based techniques are unable to identify the recently launched phishing data, such as zero-day phishing websites. Machine learning techniques have been used in several recent studies to detect phishing data and function as an early warning system …

The Voice As The Ultimate Microtonal Instrument, Catherine Terrell

University Honors Theses

I wrote several songs in a non-standard tuning system, 19-equal temperament. I define and distinguish 19-equal temperament and 12-equal temperament, then explore why I decided to write in this tuning system. I argue that intonation is a tool composers can implement along with more common musical devices. After describing the methods I used to create this music, I detail how I taught performers to sing it. I then describe and analyze the several works of music I created. Through the compositional process, I found tuning to be a very effective means in expressing musical and poetic ideas.

Extra Omnes: Analyzing The United States’ And Ireland’S Methods Of Quelling The Criminal Clergy Sexual Abuse Scourge, Dana Aprigliano

Journal of Catholic Legal Studies

(Excerpt)

In late 2008, an Irish businessman was successful in legally preventing sexual assault claims from being brought against him. In explaining why one “victim” should be discredited, the court cited a threat she made against the businessman to make allegations of a sexual nature against him if he did not pay her a sum of money. In particular, she told him that if he did not pay her, she would “have him . . . ’plastered all over the front of the Evening Herald like those p[e]dophile priests.’ ” Although the businessman was not a priest or, as it …

Feminist Consciousness-Raising Groups In The Classroom, Andrea Quaid

Feminist Pedagogy

Feminist consciousness-raising (FCR) groups in the classroom are a way to facilitate conversation, enliven course content and activate a feminist practice to support student learning. Different from small group activities structured by an instructor’s prompt, FCR groups are a practice and pedagogy that help students identify “what really matters” (hooks, Teaching Critical Thinking). For example, rather than a teacher’s instruction (“please find three main points in the text to share with the full class”), students create their own prompts and facilitate their own conversations. Student agency is activated as they build conversations with one another and develop meaningful interpersonal skills …

“I Don’T Think We Do A Good Enough Job Acknowledging How Much This Space Is Needed By The Adults”: Making Intergenerational Futures At Camp Fyrefly, Ontario Ontario, Mayera Chazan, Megan Hill, Rachael Nicholls, Ziysah Von Bieberstein

Journal of Queer and Trans Studies in Education

This paper examines the liberatory potential of intergenerationality at Camp fYrefly, Ontario—an overnight summer camp for 2SLGBTQIA+ youth that is unique within its rural region. In 2023, we conducted research in partnership with Camp fYrefly, including one arts-based workshop, two focus groups, and five key informant interviews. The analysis explores one core finding: participants experience this youth-focused program as an intergenerational future-building project. Extending scholarship on queering mentorship, generativity, and futurity, the article concludes that Camp fYrefly’s intergenerationality binds past, present, and future in the collective project of queering education and making better futures possible. Intergenerationality is also what sustains …

Designated Pilot Examiner System Study - 2025, Michael Gref, Wendy Beckman

International Journal of Aviation, Aeronautics, and Aerospace

In recent years primary flight training in the United States has experienced a significant bottleneck in the form of long waits to schedule check rides with Designated Pilot Examiners. This challenge has been significant enough to warrant Congressional attention, with reforms mandated in the past two FAA Re-authorization Acts.

In 2022 a first national survey of flight schools and DPE’s was conducted to determine their perceptions of the DPE system, including feedback on the recommendations from the then recently concluded DPE Reforms Working Group. Given the anecdotal evidence of continuing long waits for check rides, a second survey was conducted …

Generation Z And The Ai Misinformation Paradox: Understanding A New Digital Vulnerability, Cecilia Cooley, Elizabeth Sperber

DU Undergraduate Research Journal Archive

This paper asks: How and why is Generation Z more vulnerable to AI-generated misinformation and disinformation than older generations? Using a comparative review of recent empirical studies, survey data, and meta-analyses from 2019–2025, this paper synthesizes research on Gen Z’s exposure to and interaction with AI-produced content across social media platforms. Although it is commonly assumed that Gen Z ’s technological exposure and fluency make them better equipped to recognize false information, findings show the opposite: Gen Z is consistently outperformed by older cohorts in detecting AI-generated falsehoods. This vulnerability stems from three intersecting factors: (1) the sheer volume of …

King Of The Jungle: Comparative Analysis Of The Geopolitical Narratives Surrounding Fordlandia And A Proposed Resort Park In El Mirador, Rachel Jaeger

DU Undergraduate Research Journal Archive

Environmental geopolitics is a field of study in which narratives about the environment are analyzed to reveal the underlying motivations and objectives they support. Using Shannon O’Lear’s (2020) framework of environmental geopolitics, I conduct a comparative analysis of the narratives surrounding two distinct development projects: Henry Ford’s historical company town in the Brazilian Amazon, Fordlandia, and a proposed ecotourism resort park in El Mirador, Guatemala. Analysis of Fordlandia reveals a narrative of American frontierism and a man-versus-nature perspective that served to paint the environment as belligerent and thereby justify corporate control and Indigenous assimilation. Narratives surrounding El Mirador differ, representing …

Greenspace Access In The Denver Metro Region: Historical Housing Policy Impact On Modern Greenspace Distribution, Brody Petig, Susan Dagget

DU Undergraduate Research Journal Archive

Access to safe, high quality, urban green spaces is widely recognized as a determinant for physical health, mental well-being, and social cohesion. Existing literature has demonstrated that race, age, gender, and socioeconomic status frequently dictate the allocation of resources and shape disparities in access to greenspace. These disparities are also often reflective of historical housing policy and zoning decisions. This paper examines greenspace access in the Denver Metro Region (DMR) and the City and County of Denver (CCD) through a social justice lens, with particular attention to the relationship between historical housing policy and contemporary trends in greenspace distribution and …
