Luxury fashion: A thematic analysis of environmental sustainability communications on U.S. retail websites
No full textThis study examines the current state of internet-based sustainability communication from leading luxury fashion brands. Corporate responsibility for sustainability is a growing concern for consumers and world organizations alike, as the impacts of corporate practices continue to contribute to a declining ecosystem. Sustainability communication is a relevant topic for practitioners and researchers who need to understand the state of the sustainability conversation within different industries. While the body of research into sustainability communication is growing, there is a lack of literature exploring web-based sustainability communication within the fashion industry, a leading industry in negative ecological impacts. This research employs a thematic analysis of textual-based content available on six leading luxury fashion brands’ U.S.-based corporate websites. Through repetitive thematic analysis, this research identifies key sustainability subject matter and communication approaches within the luxury fashion brands’ communications and explores how the subjects and themes interact. This study contributes to the growing body of literature on fashion sustainability communications and offers insights into what subjects luxury fashion brands value in sustainability and whether they effectively communicate their commitments and values. The research has practical implications for fashion communicators and marketers while advancing scholarly understanding of sustainability communication within the fashion industry
Perception of fire risk from lithium-ion batteries in micromobility devices: A study among OSU students
No full textThe rise of Lithium-Ion batteries in micromobility devices, such as e-scooters and e-bikes, has grown fire safety concerns in urban environments. Recent incidents with Lithium-Ion batteries have shown up the fire hazard that represent these products. Previous research has shown that the common owners are people of the age of studying and with low income. Making university housing a clutch for this hazard. This study explores the perception of fire risk associated with lithium-ion battery use among students at Oklahoma State University.
Through a survey of semi structured interviews, data was collected on students´ behaviors of electric micromobility, risk perception and previous knowledge about its relationship with fire risk.
The study used a qualitative method, with inductive content analysis that resulted in a prevailing perception of low risk and a constant of unsafe practices while parking and charging the electric micromobility devices
From truce to tragedy: The duration effect of ceasefires on renewed conflict deadliness
No full textThis study investigates the effect of ceasefire duration on the deadliness of recurring conflicts. While ceasefires are typically seen as a step toward peace, this research explores a counterintuitive dynamic: longer ceasefires may contribute to more deadly conflict episodes when war resumes. Drawing on theories of bargaining, the study hypothesizes that protracted ceasefire periods enable warring parties to bolster their military capacities, recruit combatants, and increase combat readiness. Utilizing a cross-national dataset of civil wars and applying regression analysis, the study tests whether longer ceasefires are statistically associated with higher battle-related deaths in subsequent conflict episodes. The findings aim to contribute to the literature on conflict recurrence by highlighting how the duration and other characteristics of ceasefires influence war dynamics, offering implications for international mediators and peacebuilders seeking sustainable resolutions to civil wars
“I'm trying to remember the distance formula, but I can’t” secondary students’ conceptual understanding of the distance between two points using visual representations
No full textIn the United States, secondary mathematics curricula often prioritize procedural skills over conceptual understanding, which has been shown to hinder long-term retention and the development of foundational knowledge for future mathematical thinking. This study explores how secondary students conceptualize and recall the distance between two points when instruction includes visual representations. Through qualitative methods, including task-based interviews with 15 students from Algebra I, Geometry, and Algebra II, this research examines how students reason through distance tasks. The most common reasoning strategies used by students included "Count Diagonally," "Slope," "Count 1-Dimension," "Rotate," and "Count Legs." After participating in the task-based interview using the instructional activities of an initial Hypothetical Learning Trajectory (HLT), participants demonstrated a narrowing of reasoning strategies when tackling distance tasks, leading to improved success rates in identifying the correct solutions. A refined HLT is presented with modifications based on the findings. These findings also contribute to the literature on students’ development of anticipatory schemes for finding the distance between two points and provide valuable insights for educators and curriculum designers
On the “bi-phase” of fluorescence to scattering with single-fiber illumination and detection: A quasi-analytical photon-transport approach operated with center-illuminated area detection
No full textBi-phasic (with a local minimum) response of fluorescence to scattering when probed by a single fiber (SF) was first observed in 2003. Subsequent experiments and Monte Carlo studies have shown the bi-phasic turning of SF fluorescence to occur at a dimensionless reduced scattering of ~1 and vary with absorption. The bi-phase of SF fluorescence received semi-empirical explanations; however, better understandings of the bi-phase and its dependence on absorption are necessary. This work demonstrates a quasi-analytical projection of a bi-phasic pattern comparable to that of SF fluorescence via photon-transport analyses of fluorescence in a center-illuminated-area-detection (CIAD) geometry. This model-approach is principled upon scaling of the diffuse fluorescence between CIAD and a SF of the same size of collection, which expands the scaling of diffuse reflectance between CIAD and a SF discovered for steady-state and time-domain cases. Analytical fluorescence for CIAD is then developed via radial-integration of radially resolved fluorescence. The radiance of excitation is decomposed to surface, collimated, and diffusive portions to account for the surface, near the point-of-entry, and diffuse portion of fluorescence associated with a centered illumination. Radiative or diffuse transport methods are then used to quasi-analytically deduce fluorescence excited by the three portions of radiance. The resulting model of fluorescence for CIAD, while limiting to iso-transport properties at the excitation and emission wavelengths, is compared against the semi-empirical model for SF, revealing bi-phasic turning [0.5~2.6] at various geometric sizes [0.2, 0.4, 0.6, 0.8, 1.0 mm] and a change of three orders of magnitude in the absorption of the background medium. This model projects a strong reduction in fluorescence versus strong absorption at high scattering, which differs from the semi-empirical SF model’s projection of a saturating pattern unresponsive to further increases in the absorption. This framework of modeling fluorescence may be useful to project frequency-domain and lifetime pattens of fluorescence in an SF and CIAD.Electrical and Computer Engineerin
Comparing qualitative damage assessments to FDS predicted heat distribution: A proposed methodology for forensic fire origin determination
No full textThe fire investigation industry has been increasingly called upon to create, update, and validate systematic methodologies for testing and developing area of origin hypotheses. To date, the research has focused on methods to test or determine a particular area of origin within a single compartment. However, the modern fire investigator often finds themselves in situations in which multiple compartments within a structure have endured significant damage due to post-flashover burning schemes, which makes the determination of the compartment of origin a difficult endeavor. Often, fire investigators have utilized computational fluid dynamics (CFD) software such as the Fire Dynamics Simulator (FDS) to assist in evaluating fire effects and behavior in such complex scenarios. While several large-scale multi-compartment fire investigations have utilized FDS to test or develop a compartment of fire origin hypothesis, no general methodologies have been proposed for such an investigation. This research seeks to build upon previous research and methodologies applicable to a single compartment and develop and validate a methodology for the utilization of FDS to create a data matrix that can be utilized to test or determine a compartment of origin hypothesis in a post-flashover environment. A prescribed qualitative methodology is utilized to synthesize macro scale fire effects and damage distributions, witness statements, and ventilation variations. Multiple FDS simulations were run and the data matrixed for comparison to the scene assessment
Analysis of benthic foraminifera populations from the Southern California Ocean Disposal Site #2 to determine the extent of DDT contamination
No full textFrom the 1940’s to the 1970’s, chemical companies disposed of DDT chemical waste barrels by dumping them into the ocean between Catalina Island and Los Angeles, California. Metabolization of DDT up through the food web caused marine wildlife populations to be severely impacted around the island and human carcinogens became a major concern. In August 2021, the R/V Falkor expedition FK210726 visited the disposal site to collect sediment, water, and biological samples from around the barrels. The sediment samples were processed and picked for analyzing populations of benthic foraminifera, microscopic protists that form a shell known as a test and are commonly used as ecological and environmental monitors. In this study, benthic foraminifera populations are counted and compared to geochemical results from sediment samples to determine whether the chemical waste is still affecting the surrounding environment and to what extent it may be affecting local wildlife, and in turn the human population
Consumer behavior of promotions: Do free bets and bonuses encourage riskier behavior in sports gamblers?
No full textThe number of people who sports bet and gamble has steadily increased over the past few decades, but with the rise of promotions and other types of “free bets,” that number has spiked (delasport.com). The launch of marketing campaigns and promotions focused on sports betting could have contributed to this spike. Today, it has become common for people to use numerous sportsbooks and websites to place bets and wager money. I propose that these advertisements and the game-like style of sportsbook apps have led to a potential shift in consumers’ attitudes and behaviors towards sports gambling.
This study focuses on identifying students’ perceptions of sports betting and whether or not utilizing these “free bet” promotions leads to a behavior shift in gamblers' minds to perceive risk less and engage in riskier betting behavior. The data was collected by conducting an extensive literature search on sports betting and the consumer behavior behind it, and by conducting an online survey using Qualtrics. The data from the survey found that 61.5% of respondents said they would use their promotions and free-bets on higher risk bets
Derivation and characterization of hybrid bovine x bison embryonic stem cell lines
No full textEmbryonic stem cells (ESCs) are pluripotent cells derived from the inner cell mass (ICM) of blastocysts, capable of differentiating into all three germ layers and maintained indefinitely in culture under proper conditions. ESCs are widely used in developmental biology and regenerative medicine due to their self-renewal and differentiation potential. In livestock, they offer powerful applications in genetic improvement and reproductive technologies. Hybrid ESCs provide a unique in vitro platform to investigate parent-of-origin effects, imprinting regulation, and gene expression dynamics across species, advancing our understanding of how genetic and epigenetic mechanisms operate in interspecies systems. This project aims to establish and validate ESC lines derived from bovine x bison hybrid embryos, which represents a novel and valuable model for exploring both beefalo research and the interplay of genetic and epigenetic inheritance. Validation of ESC lines involves multiple complementary approaches to confirm their pluripotency and genomic integrity. In this study, ESC lines were assessed through immunofluorescence staining for key pluripotency markers (OCT4 and SOX2), embryoid body (EB) formation to evaluate in vitro differentiation capacity and karyotyping to ensure chromosomal stability. Additionally, a teratoma assay will be conducted in collaboration with Dr. Amanda Patterson (University of Missouri) as part of future in vivo validation. These assays are crucial to demonstrate the quality and utility of derived cell lines for future applications. To our knowledge, this study reports the first successful derivation and preliminary validation of ESC lines from bovine x bison hybrid embryos. Establishing culture conditions and validation protocols for these cells will not only advance hybrid embryo research but also support long-term goals in genetic preservation, reproductive biology, and the study of epigenetic mechanisms in livestock species
From education to exile: The Indian Civilization Fund Act, the dispossession of Seneca land, and education's impact on Indian Removal policies
No full textThis research examines the importance of the Indian Civilization Fund Act to the development of Indian policy in the nineteenth century, its subsequent impact on Indian Removal policies, and how the Seneca people strategically engaged with US policy as an expression of sovereignty. Historians have yet to investigate the full impact that these government-funded mission schools had on the creation of Indian policy throughout the 1820s and the larger impact on Native American Boarding Schools. This study establishes the US government officials’ motivations behind passing educational policies and then removal policies, while also investigating how Indigenous peoples navigated these federal policies to best benefit their nations. Utilizing sources including speeches, newspapers, government reports, missionary documents, and letters, this research helps place the Indian Civilization Fund Act in conversation with histories of the Early Republic, Boarding Schools, and Indian Removal. This research centers on the Seneca Nation of Indians' experiences on the Alleghany, Buffalo Creek, and Cattaraugus Reservations throughout the 1820s to examine the discussions happening at the local level amongst the tribe to understand how Indigenous nations interacted with early American attempts at Indian policy. The Indian Civilization Fund Act and Seneca narratives expand our understanding of the Early Republic, as this Act functioned as a transitional program that led to further projects of attempted genocide. The government’s funding of Indian education started during the 1820s and left an impact on Indian policy for the next century. The Indian Civilization Fund Act is integral to the development of Indian policy throughout the 1820s, as it represented a transitional period in US Indian policy that emphasized a potential partnership between Indigenous nations who engaged with assimilative policies and the emerging United States government. This study pushes the timeline of Boarding School histories back by sixty years to explain the longer legacy of assimilative policies and the ways Indigenous nations engaged with policies in ways that best benefited their nation
