Visual Ecologies And Language In Digital Environments: Narratives From First-Year Composition Students In Multimodal Learning, Elizabeth Escobedo Salazar
Visual Ecologies And Language In Digital Environments: Narratives From First-Year Composition Students In Multimodal Learning, Elizabeth Escobedo Salazar
Open Access Theses & Dissertations
The expansion of Information and Communication Technologies (ICTs) developed new perceptions of learning, communication processes, shaped university students' new practices and has brought about significant changes in social dynamics. Images and visual language have become central to the way humans communicate, communication processes have changed, and the composition and creation of arguments have changes. In this context, the use of multiple screens (Multiscreens) has led to multitasking, but additionally in digital contexts where students are hyper-connected. They do their homework while on social media, texting, creating videos, using a new app, or watching a movie on YouTube or Netflix. This …

Advances in the prognostication, monitoring, and treatment of both the acute and chronic leukemias have led to drastically improved outcomes over the past 2 decades. With the advent of targeted therapies, including antibodies such as blinatumomab and inotuzumab and small molecule inhibitors, such as the BCR::ABL1 tyrosine kinase inhibitors, Bruton tyrosine kinase inhibitors, and venetoclax, the treatment landscape of leukemia has drastically changed, improving survival outcomes while relying less on overall chemotherapy intensity in many leukemia types. This progress has allowed the categorization of more leukemia types as favorable (i.e., chronic lymphocytic leukemia, younger acute lymphoblastic leukemia [patients younger than …

Research Collection College of Integrative Studies
Every year the list lengthens of cities with some sort of ‘smart city’ public policy. In some, it emerges as the latest in a long line of urban digital and information communication policies. In others, the introduction of the notion of the ‘smart city’ marks a departure from past approaches to public policy. Additionally, the more studies emerge of actual smart city policies, then the less definitional agreement there seems to be. Nevertheless, that we have witnessed in the last two decades the ‘repeated instance’ of smart cities emerging in cities around the world seems incontrovertible. Like so much urban …

Remaking The Smart City Through The Covid-19 Pandemic: Seoul, Singapore, Taipei, Orlando Woods, I-Chun Catherine Chang, Haeran Shin
Research Collection College of Integrative Studies
The COVID-19 pandemic has proven to be a catalysing force for urban innovation in general, and for smart city agendas specifically, throughout the world. From the development of contact tracing technologies and the enforcement of quarantine and safe distancing measures, to the dissemination of public health information and advancement of telehealth rollouts, the promises of “smart” technologies to reveal and govern patterns of socio-spatial contact and mobility can be found at the core of effective city management during the pandemic. Arguably nowhere is this truer than in the cities of Seoul, Singapore and Taipei, where the Asian developmental state was …

Seeing Beyond The State: Private Sector-Led Smart City Governance In Bsd City, Indonesia, Prerona Das, Orlando Woods, Lily Kong
Research Collection College of Integrative Studies
In recent decades new cities have sprung up at a rapid pace, aided by private sector funding (Hogan et al., 2012). Within the realm of smart city development, private sector influence over urban governance has substantially increased, particularly through Public-Private Partnerships (PPPs). However, in Indonesia, there is an emerging trend of the private sector exerting significant control over ‘independent’ greenfield smart cities beyond state-led frameworks. This paper develops the idea of seeing beyond the state which involves looking past conventional state-centered approaches to urban governance. It considers instead how power and control are exercised outside or beyond the usual boundaries …
Spanish Heritage Speakers And Latinidad: How Spanish Fluency Influences Self-Perceived Latinidad Among Heritage Speakers, David Alejandro Rivera Sandoval, Gladys Valle
Spanish Heritage Speakers And Latinidad: How Spanish Fluency Influences Self-Perceived Latinidad Among Heritage Speakers, David Alejandro Rivera Sandoval, Gladys Valle
Undergraduate Theses and Capstone Projects
Abstract of Research: This study examines 1) how heritage speakers' self-perceived proficiency and fluency in Spanish influence their identity as Latinos, and 2) the generational similarities and differences in their lived experiences. Through surveys and interviews, the relationship between Spanish proficiency and fluency and perceived Latinidad among nine Spanish heritage speakers (with Latin American ancestry) has been assessed. The research suggests that no statistically significant relationship was found between language proficiency or fluency and perceived Latinismo. However, qualitative findings revealed that participants construct their Latino identity based on cultural values, lived experiences, and a sense of belonging rather than language …
More Alike Than Not: The Open Access Preferences Of Humanities Scholars, Rachel E. Scott, Ana Dubnjakovic
More Alike Than Not: The Open Access Preferences Of Humanities Scholars, Rachel E. Scott, Ana Dubnjakovic
Faculty and Staff Publications – Milner Library
Several studies have noted that humanists have not been as quick or enthusiastic in their adoption of Open Access (OA) as their colleagues in other disciplines. This article leverages the Ithaka S+R US 2021 Faculty Survey to provide contextualized analysis of the OA and Open Education Resources (OER) preferences of humanities scholars, as well as some practices related to OA and OER, relative to their colleagues in other disciplines. Findings suggest that although humanists do stand apart in many OA preferences, the small effect sizes render these differences less important than previously suspected. The implications of these findings are considered …

(Un)Just Transitions For Youth And The Disabled? The Exclusionary Pressures Facing Science, Technology, Engineering And Mathematics (Stem) Education, Elizabeth Done, Helen Knowler, Irina Lazar, Sylvia Hayes, Joshua Lait, Andrea Perez-Porres
School of Law, Humanities and Social Sciences
This paper highlights the under-representation of young people with disabilities in STEM subjects and career pathways, with particular reference to the engineering sector given its prominent role in the design of energy systems related to net-zero policies. We consider the role of physical infrastructure, and pedagogic and representational practices, in facilitating the marginalisation and under-representation of young people with disabilities. Ultimately, we seek a broader understanding of the ‘just transition’ that acknowledges the role of education in ensuring the active participation of all young people, regardless of learning difficulty or disability or social identity, in that transition. The research is …
Model Fatigue: Debugging Hector Through Climate Computational Aesthetics, Helen Pritchard, Guillemette Legrand
Model Fatigue: Debugging Hector Through Climate Computational Aesthetics, Helen Pritchard, Guillemette Legrand
School of Art, Design and Architecture
In this paper, we document three computational features of the climate model Hector by translating the modalities through which the model predicts climate futures in a game engine. We build upon the computational aesthetics of M. Beatrice Fazi and Matthew Fuller (2016) and suggest additional characteristics of computation to their proposed list. We argue that these computational aesthetics are essential to climate modelling. The three features are time series, couplings and cosmograms, which are based on our practical and theoretical inquiry into Hector’s computation and literacy. We develop a framework that employs two processual methods: translating the model’s operations into …
Mmlu-Prox: A Multilingual Benchmark For Advanced Large Language Model Evaluation, Weihao Xuan, Et. Al.
Mmlu-Prox: A Multilingual Benchmark For Advanced Large Language Model Evaluation, Weihao Xuan, Et. Al.
Research Collection School Of Computing and Information Systems
Existing large language model (LLM) evaluation benchmarks primarily focus on English, while current multilingual tasks lack parallel questions that specifically assess cross-lingual reasoning abilities. This dual limitation makes it challenging to assess LLMs’ performance in the multilingual setting comprehensively. To fill this gap, we introduce MMLU-ProX, a comprehensive benchmark covering 29 languages, built on an English benchmark. Each language version consists of 11,829 identical questions, enabling direct cross-lingual comparisons. Additionally, to meet efficient evaluation needs, we provide a lite version containing 658 questions per language. To ensure the high quality of MMLU-ProX, we employ a rigorous development process that involves …

The Simulation Of Hyperspectral Observations By The Upcoming Spacecraft "Arab Satellite 813", With The Radiative Transfer Model Sciatran, Sara Maher Alhasan
Theses
The Arab Satellite 813, which is scheduled to be launched in 2025/2026 by the UAE Space Agency, is set to increase earth observation and monitor the climate across the middle East and North Africa (MENA) region. This study uses the SCIATRAN radiative transfer model which was originally developed for the Envisat mission to simulate the hyperspectral observation specifically tailored for the satellite's payload. Using calibrations that were used by the previous research in their SCIATRAN V4.6 study and adjusting parameters like the Leaf Area Index (LAI), a simulation which agreed robustly with the benchmarks set by the previous research was …
The Heart Of Policing: Exploring The Essence Of The Phenomenon Between Organizational Culture And Police Officer Job Satisfaction, Charles C. Palmer
The Heart Of Policing: Exploring The Essence Of The Phenomenon Between Organizational Culture And Police Officer Job Satisfaction, Charles C. Palmer
Electronic Theses and Dissertations
The purpose of this transcendental phenomenological qualitative study was to explore the essence of the phenomenon between organizational culture and police officer job satisfaction among rural law enforcement agencies in Oklahoma. Retaining police officers has become an increasingly challenging task for law enforcement organizations across the United States, as high turnover, costly recruitment, and voluntary resignations continue to strain departments. While previous research has primarily examined demographic and occupational variables influencing satisfaction, limited attention has been given to how organizational culture affects the lived experiences of U.S. police officers. Guided by Edgar Schein’s organizational culture theory, this study examined how …

Uni’S First Woman Professor: Laura Ensign And The Struggle For Fair Pay, Rank, And Faculty Governance Under Gilchrist And Seerley, Thomas G. Connors
Faculty Book Gallery
At 29, Laura Ensign’s appointment to the faculty of Iowa’s new State Normal School should have been an unqualified triumph. Yet her hiring by the Board over the objections of James Gilchrist, the school’s principal, placed her under an administrator who detested her from the start. She lived, ate, and worked with her colleagues, pupils, and Gilchrist and his family in the same isolated building on a hill two miles from town. Near her wits’ end after eight years, Ensign tried one final maneuver, one so risky that it would have cost her job had it failed: She began secretly …
“Justice Of Our Own”: Defining Success At The Red Hook Community Justice Center, Hadar Dancig-Rosenberg, Peter Dixon
“Justice Of Our Own”: Defining Success At The Red Hook Community Justice Center, Hadar Dancig-Rosenberg, Peter Dixon
Vanderbilt Law Review
This study examines how success is defined at the Red Hook Community Justice Center in Brooklyn, NYC, through a participatory, community centered lens. Moving beyond standard metrics, it articulates a locally grounded vision of success centered on empowerment, support, systemic accountability, and community trust. Drawing on the Everyday Peace Indicators approach, we convened nine focus groups and two public voting sessions with neighborhood residents, justice professionals, youth, former defendants, and family members. Participants generated and ranked 72 indicators, which we thematically clustered into six key categories reflecting the diverse contexts in which participants perceived the Center's impact: (1) rehabilitation and …

Research SummaryAs a result of the 2022 Dobbs v. Jackson Women's Health Organization decision that overturned Roe v. Wade, state lawmakers can and have enacted abortion restrictions, including criminal penalties targeting those who seek, provide, or assist with abortion. Given the current legal landscape, it is imperative to assess public opinion regarding the endorsement of punishments for illegal abortion. We conducted multivariate analyses to assess factors associated with punishment endorsements for an illegal abortion for the pregnant woman and healthcare provider. We also evaluated whether individual beliefs (i.e., abortion legality) and contextual factors (i.e., living in an abortion-restrictive state) may …

Geology Faculty Publications and Presentations
Predicting physical and chemical erosion rate responses to climate change are an ongoing challenge in geomorphology. A promising approach for investigating this is by measuring transient variations in physical and chemical erosion rates during climatically variable time periods, which can be accomplished by measuring cosmogenic nuclide concentrations and chemical depletion in sedimentary deposits. Interpreting such measurements warrants applying landscape evolution models that track variations in topography, cosmogenic nuclide concentrations and chemical depletion in soils. We applied a recently developed model that tracks these quantities at Little Lake, Oregon. Previous studies documented variations in cosmogenic nuclide concentrations and chemical depletion in …

Multiplatform mutational and gene expression profiling complemented with proteomic and metabolomic spatial mapping were used on the whole-organ scale to identify the molecular profile of bladder cancer evolution from field effects. Analysis of the mutational landscape identified three types of mutations, referred to as α, β, and γ. Time modeling of the mutations revealed that carcinogenesis may span 30 years and can be divided into dormant and progressive phases. The α mutations developed in the dormant phase. The progressive phase lasted 5 years and was signified by expanding β mutations, but it was driven to invasive cancer by γ mutations. …

From Pachymeningitis Hemorrhagica To Abusive Head Trauma: A Journey Through The Centuries, Oliver Berthold, Flora Blangis, Christopher Spencer Greeley
Faculty, Staff and Students Publications
The development of medical knowledge follows specific principles. These also apply to abusive head trauma. The seminal literature from the early 20th century is based on earlier research from Europe, which is fundamental to understand the evolution of understanding and nomenclature of abusive head trauma. A review of original medical literature on intracranial injuries in children, published in German, English, and French, was conducted using PubMed and Google Scholar for articles before 1950. The primary search focused on subdural hemorrhages and pachymeningitis in children, followed by a snowball search of references. Full texts of available manuscripts were reviewed. Primary literature …

Potentially Toxic Metals, Anthropogenic Microfibres And Other Microplastics In Sediments From A Small, Urban Estuary (Plym, Southwest England), Kwong Ricky Li, Andrew Turner
School of Geography, Earth and Environmental Sciences
Anthropogenic microfibres (AMFs) and microplastics (MPs) are pervasive and ubiquitous environmental contaminants of growing concern. However, their study in geosolids, like sediments, is often conducted in the absence of other important geochemical and anthropogenic markers. In the present study, surface and subsurface sediments from the Plym Estuary, southwest England, have been analysed for AMFs and MPs along with organic matter (as loss on ignition; LOI), calcium, iron, manganese and potentially toxic metals (PTMs). The latter were heterogeneously distributed throughout the estuary because of multiple inputs and variations in sediment granulometry. AMFs were mainly constructed of cellulosic and petroleum-based polymers and …

School of Geography, Earth and Environmental Sciences
Tritium (3H), an isotope of hydrogen, is a by-product of the nuclear industry. Decommissioning and normal operations of nuclear facilities can generate tritiated stainless-steel particles (T-SSPs) that could be unintentionally released into the environment. Considering tritium's physicochemical properties and the proximity of nuclear facilities to water bodies, assessing the behaviour and potential effects of these particles in the aquatic environment is imperative. In the present study, marine mussels, Mytilus galloprovincialis, were exposed to: (a) hydrogenated, non-radioactive stainless-steel particles (H-SSPs) (10 mg L−1) (b) T-SSPs (1 and 10 MBq L−1) and (c) tritiated water (HTO) …

Water that flows through permeable ultramafic rocks produces high abundances of molecular hydrogen (H2), methane (CH4), and other small organic molecules. Such products can fuel life in the rocky subseafloor, be extracted for energy, and may have played a role in pre-biological chemical synthesis on early Earth or other planetary bodies. The International Ocean Discovery Program drilled a new 1268-m-deep borehole (U1601C) into serpentinized mantle with minor gabbroic rocks on the Atlantis Massif, ∼800-m north of the Lost City hydrothermal field (30°N, Mid-Atlantic Ridge). Measured temperatures of the disturbed borehole reached 91.3 °C, and equilibrated temperatures …
