Representations Of Cartel Leaders In Narcocorridos: A Reflexive Thematic Analysis, Gael Gamboa

Theses and Dissertations

Narcocorridos have become one of the most recognized expressions of narcoculture in Mexico. Despite growing scholarly interest in narcoculture, relatively few studies have examined how cartel leaders are represented across narcocorridos. This study addresses this gap by examining the symbolic representations of Joaquín “El Chapo” Guzmán, Miguel Ángel Félix Gallardo, and Amado Carrillo Fuentes in narcocorrido lyrics. The study is guided by cultural criminology and subculture theory; this study employed a qualitative research design using reflexive thematic analysis. A purposive sample of 25 narcocorridos was analyzed to identify recurring patterns in the representation of cartel leadership. As a result, six …

Personal Authenticity For Engagement And Transfer In Introductory Cybersecurity Education, Daniel T. Hickey, Ronald J. Kantor

Journal of Cybersecurity Education, Research and Practice

Abstract—This conceptual/theoretical paper explores how personal authenticity might promote generative learning in introductory cybersecurity courses. Generative learning transfers confidently to future educational, professional, personal, and testing situations. This cycle of design-based research addresses the concern that more typical professionally authentic contexts (e.g., hospitals, banks, etc.) may be alien and overwhelming to many students, particularly those in introductory courses and/or from non-professional families and communities. If so, this leads to “inert” knowledge that does not transfer. Personal authenticity is rooted in expansive framing, a modern theory of learning transfer. We reframe expansive framing as personal authenticity to make it …

Comparative Analysis Of Reaction Wheels And Control Moment Gyroscopes For High-Capacity Orbital Data Centers In Sun-Pointing Mission Profiles, Chih Ta Wu, Po Hsun Yen, Jen Hao Cheng, Kai Kuo Liao, Shang Jung Lee

The purpose was to examine early mentor-mentee match dissolution and low mentor retention in a nonprofit youth mentoring through the lens of the ecological systems theory and program evaluation framework. The practice-focused research questions were: How do volunteer mentors and program staff perceive the organizational practices and culturally responsive strategies that influence mentor effectiveness and retention in youth mentoring programs, and what organizational and systemic challenges do Black male mentors encounter in …

Optical Advantages In Using Extremely Stable Materials In Small Satellite Telescopes, Tony Hull, Jesse Bonfeld, Dustin Ruth, Florian Gollier, Janina Krieg, Thomas Westerhoff, Jacqueline Caraballo

Small Satellite Conference

Small-satellite telescopes experience continuous thermal transients from changing Sun and Earth view factors plus CONOPS → temperature gradients T(xi) → distort mirrors/metering if the material is sensitive to temperature.

Transients are partially mitigated by diffusivity, but only with uniform temperature changes. Orbital and CONOPS transients are not uniform → The architect must examine the material response to realistic transients and gradients.

Optimal optical performance is supported by appropriate passive material attributes!

Neuronal Expression Of Bromodomain Proteins Alters Neuronal Health And Peripheral Protein Homeostasis To Promote Longevity, Naibedya Dutta, Daniel Hicks, Edgar Esparza, Anna Entin, Priyadharshini Vijayakumar, Caitlin M Lange, Tripti Nair, Elijah A Roditi, Athena Alcala, Maxim Averbukh, Matthew Vega, Rebecca Aviles Barahona, Caitlin Mctygue, Veronica Kuo, Juri Kim, Herbert Anson, Aeowynn J Coakley, George Wang, Steven E Pilley, Max A Thorwald, Whitaker Cohn, Sean P Curran, Nicolas Brouilly, Caroline Kumsta, Rachel N Arey, Peter J Mullen, Gilberto Garcia, Ryo Higuchi-Sanabria

Faculty, Staff and Students Publications

Longevity and stress resilience require precise coordination of gene expression programs across tissues. Here, we demonstrate that overexpression of the chromatin reader bet-1 specifically in neurons of Caenorhabditis elegans promotes organismal longevity and stress resistance via cell-nonautonomous signaling. Neuronal bet-1 elicits a neurotransmitter-dependent signal that activates the conserved stress-responsive transcription factor HSF-1 in the intestine, enhancing proteostasis, oxidative stress resistance, metabolic remodeling, and immune defense. Life span extension by neuronal bet-1 requires both hsf-1 and daf-16 in neurons but only requires hsf-1 in peripheral tissues. Using bulk RNA sequencing, we reveal distinct prolongevity pathways that include enhanced heat-shock response, proteostasis, …

The Effects Of Home Blood Pressure Monitoring And Hospital Readmission For Hypertensive Patients, Danielle Alston

Walden Dissertations and Doctoral Studies

Within this executive summary, the type of project discussed is an organization change project to address a health issue in chronic disease management, which is hypertension. Nearly 116 million American adults are affected by hypertension, which remains a leading force for preventable hospitalizations, emergency department visits, and cardiovascular-related mortality in the United States. Unexpected readmissions due to hypertension create system-wide strains, increased financial burden and decreased patient satisfaction. Hence, the question: In adults with hypertension, does remote home blood pressure monitoring, compared with standard office-based follow-up, reduce the rate of urgent care visits and hospital admissions over a 30-day period? …

The Individual And Combined Effects Of Individualism-Collectivism Orientation And Mental Health Stigma On Perceived Social Support In Firefighters, Emma Schafer Schutte

Walden Dissertations and Doctoral Studies

Repetitive trauma exposure predisposes firefighters to a variety of mental health issues. Despite efforts to expand mental health resources and peer support, stigma remains a significant barrier to formal (professional) and informal (peer) support-seeking within the fire service. According to social influence theory, firefighters may avoid using available support services because they perceive support-seeking as stigmatized by their peers and feel compelled to conform. Research across cultural groups suggests that individualism-collectivism orientation, which defines how individuals assign value to individual or group needs, has nuanced effects on perceptions of social support. However, the interplay of individualism-collectivism orientation, stigma, and perceived …

Heritable Transgenic Schistosomes As A Living Platform For Sars-Cov-2 Neutralizing Antibody Secretion, Wannaporn Ittiprasert, Bruce A Rosa, Sergej Djuranovic, Makedonka Mitreva, Et Al.

2020-Current year OA Pubs

We report the generation and propagation of not only the first heritable transgenic schistosome line but also a line that secretes a functional therapeutic protein in vivo. Using multiplexed CRISPR/Cas-mediated homology-directed knock-in targeted to a predicted genomic safe-harbor, we inserted a VHH-IgG1 Fc (termed C5-Fc) transgene into Schistosoma mansoni eggs. Single-miracidium infections of Biomphalaria glabrata yielded parental P0 lines; serial passage through snail and mouse hosts produced an F2 cohort in which all parasites carried the C5-Fc transgene and secreted C5-Fc into the murine venous circulation. Molecular assays confirmed chromosomal insertion, germline transmission and systemic secretion. Sera from mice harboring …

Altered Postnatal Chromatin Development In The Nucleus Accumbens Primes Enduring Stress Sensitivity, Rebekah L Rashford, Lisa Z Fang, Michael Deberardine, Hye Ji J Kim, Laura W Hirschfield, Ella Cervi, Mason R Barrett, Jeremy M Thompson, Meaghan C Creed, Catherine Jensen Peña

2020-Current year OA Pubs

Early life stress (ELS) sensitizes individuals to subsequent stressors to increase lifetime risk for psychiatric disorders. Within the nucleus accumbens (NAc)-a key limbic and reward-associated brain region-ELS sensitizes both cellular and transcriptional response to later stress, which are programmed by enduring epigenetic changes. Among the histone modifications persistently enriched by ELS in NAc is H3K4me1, which is associated with open chromatin and epigenetic priming of genomic enhancers. Here, we sought to determine whether H3K4me1 enrichment in NAc was sufficient to prime cellular and behavioral responses to adult stress. Viral-mediated overexpression of the histone H3 monomethyltransferase

An Exceptional Model At Sea: Functionalist Targeting And The Legal Vulnerability Of Maritime Civil Defense In Japan, Kentaro Furuya

International Law Studies

The intensifying security competition in East Asia, characterized by persistent territorial disputes and the potential for major regional contingencies, has placed the Japan Coast Guard (JCG) at a strategic crossroads. The 2023 Control Guideline, which outlines the JCG’s role during armed attacks, has further heightened interest in the agency’s legal status. This article examines the critical gap between Japan’s domestic legal framework and the international law of naval warfare, specifically addressing how the potential classification of JCG assets as military objectives undermines the safety of maritime civil defense operations.

While the Japanese government firmly maintains the JCG’s status as a …

Lightweight Open Source On-Spacecraft Machine Learning With Mlpack And F Prime, Ryan R. Curtin, Scott M. Gilliland, Sterling L. Peet

Small Satellite Conference

Onboard machine learning is an increasingly important topic in spaceflight systems, as machine learning and AI models are increasingly used for data processing, anomaly detection, attitude control systems, and other predictive applications. However, successfully deploying a machine learning model in a spaceflight computing environment is fraught with difficulty, as spaceflight computing environments are low-resource, but typical machine learning software solutions are implemented in languages like Python, which require an interpreter and other heavyweight dependencies. It is therefore virtually mandatory for any on-spacecraft machine learning to be written with lightweight toolkits that minimize dependencies and resource usage.

We demonstrate a solution …

Payload Operation Using On-Board Vision Language Model, Meirav Nevo, Oshri Fatkiev, Guy Zaidman, Doron Shterman

Small Satellite Conference

The rapid maturation of multimodal vision-language models (VLMs) has significantly expanded artificial intelligence applications at the edge, including spaceborne systems. In this work, we present one of the first demonstrations of deploying a compact vision-language model directly on a very-high-resolution Earth-observation satellite payload processor, enabling autonomous on-orbit scene understanding and near real-time decision-making. This represents a paradigm shift in satellite operations, moving from ground-centric processing toward intelligent, self-directed spacecraft. 

Conventional Earth-observation missions rely on ground-based image processing and interpretation, introducing latency, downlink bandwidth constraints, and limited operational responsiveness. By embedding a VLM on board the satellite, visual reasoning can be …

The Space Cognitive Network: From Fractionated Spacecraft To Collaborative Ai-Enabled Space Infrastructure, Owen Brown, Dennis Gatens, Fred Kennedy, John Moberly, Rusty Thomas, Derek Tournear

Small Satellite Conference

Over the past two decades, small satellite architectures have undergone a fundamental transformation — from platform-centric spacecraft, to globally distributed data-centric constellations. This paper traces that evolution and argues that a third shift is now underway: cognition-centric space architectures enabled by artificial intelligence (AI) as infrastructure. 

We begin by revisiting one of the earliest disruptive space architecture concepts: the fractionated satellite. Developed at the Defense Advanced Research Projects Agency (DARPA) in the mid-2000s, the fractionation concept decomposes a monolithic spacecraft into distributed elements. While the original vision emphasized physical subsystem decomposition, the System F6 program ultimately revealed that the greatest …

Satellite Constellations 2026 - Survey, Trends And Economic Viability, Erik Kulu

Small Satellite Conference

This paper presents the commercial satellite constellation landscape as of Jan 1, 2026. It is based on data from the public NewSpace Index (www.newspace.im), which has tracked commercial constellations since 2016 and contained 456 entries by the end of 2025. 

Many constellation operators have launched initial satellites or small batches, but only a few have reached regular launch rates. Deployment has generally been slower than announced, with many projects scaling back plans or delaying timelines. SpaceX has a significant lead, having launched more than 11,000 Starlink satellites. The next largest commercial operators, Planet and OneWeb, remain well below 1000 satellites. …

The extragalactic background light (EBL) (Fig. 1) is the diffuse light arriving from outside our Galaxy. Previous studies revealed that the near-infrared EBL is several times brighter than the integrated galaxy light (IGL).

This excess may originate from the first stellar objects in the early universe or from intrahalo light. Their spectra differ in the visible range (Fig. 2), so the visible EBL is the key to identifying the origin.

Ground-based observations are contaminated by foregrounds such as airglow. We therefore developed VERTECS (Visible Extragalactic background RadiaTion Exploration by CubeSat) to observe the EBL from space.

Cubesat Led Transmitter For Optical Communication Downlink, David Hinkley, Sam Pedrotty

Small Satellite Conference

The CubeSat radio frequency (RF) spectrum licensing step has always been long and therefore stressful to developers. With more satellites entering orbit, spectral congestion in the available RF frequency bands has become a problem. An optical-only solution eliminates this problem and provides a path for a lower power and higher throughput data link. The risk of a weather outage drives a solution that requires enough geographically diverse optical ground locations that a clear line-of-sight is always available. The Aerospace Corporation, with funding from NASA, has developed a CubeSat light emitting diode (LED) transmitter and an inexpensive commercial portable optical telescope …

Intelligence Where Data Is Born: Vision Transformer-Based On-Orbit Change Detection For Earth Sensing, Matthew Morabito, Faries Tadros, Catherine Ordun, Michael S. Sellers, Daniel Wald

Small Satellite Conference

This paper introduces a model framework for autonomous hyperspectral segmentation that couples a foundation model with a supervised segmentation head to enable compact, high performance on-orbit scene understanding. This approach is designed to deliver end-to-end onboard processing, inference, confidence scoring, and prioritization so the spacecraft performs interpretation at or near image collection time and minimizes downlink usage by transmitting only high-value or high-interest outputs rather than full image streams. A key design element is adaptive intelligence over mission lifetime: low-size, over-the-air partial models updates as small as kb-scale enable post-launch retuning and mission-specific refinement without GB-scale data transfer. By reusing …

From Competition To Complementarity: A Case Study Of Arabic-English Language Ideologies At University Of Bisha, Ahmed Yahya Mohammed Al-Hakami

UB Journal for Humanities

This study investigates the coexistence of, and tension between, Arabic and English language ideologies in Saudi higher education, focusing on University of Bisha as a case study. Drawing on quantitative data from online questionnaires (N = 138), this study examines how Arabic and English are ideologically valued, legitimised, and contested across three dimensions, namely identity, academic learning, and status. Using robust statistical analyses, including correlation and repeated-measures testing, the analysis tests whether these ideologies function primarily as competing forces, privileging one language at the expense of the other, or as complementary resources that support students’ academic experience and professional ambition. …
