In the results for the present-day interpolation, ~6 % of the coastal buffer –the total …

Habitat Associations Of Plains Spotted Skunk (Spilogale Interrupta) Across The Plains Ecoregion. And The Landcover Occupancy Models Of The Gray Fox (Urocyon Cinereoargenteus) In The Southeastern Plains Region In Arkansas, Michael Shaw

Graduate Theses and Dissertations

Much of the landscape of the United States has been altered by humans, leading to the eradication of most populations of large mammalian predators. Consequently, many species of mammalian mesopredators (medium-sized mammalian predators) have come to dominate the landscape. Species such as the gray fox (Urocyon cinereoargenteus) may appear to be on the rise and doing well due to their widespread range, but at a local scale may need monitoring and less is known in areas of its range. Others such as the plains spotted skunk have a wide range across the plains but are on the decline even with …

Geochemistry Of Metal-Rich Black Shales And Their Genetic Relationship To Mississippi Valley-Type Pb-Zn Ore Deposits, Midcontinent U.S., Noah S. Morris

Graduate Theses and Dissertations

The formation of Mississippi Valley-type (MVT) lead-zinc (Pb-Zn) ores is complex, involving an interaction of tectonic compression, hydrothermal fluid migration, and geochemical processes within the subsurface. Fundamental questions regarding this interaction remain unclear, including the source(s) of the Pb and Zn ions that make up the ores. A genetic link between black shales and MVT ores has been thought to exist because of (1) the presence of mature hydrocarbon and brine fluid inclusions within many MVT ores, (2) the association of the hydrothermal fluids that are linked to MVT ore formation with organic compounds and oil-like droplets, and (3) the …

Bayesian Learning Of Spatiotemporal Source Distribution For Beached Microplastic In The Gulf Of Mexico, David Pojunas

Graduate Theses and Dissertations

Over the last several decades, plastic waste has gradually accumulated while slowly degrading in terrestrial and oceanic environments. Recently, there has been an increased effort to identify the possible sources of plastic to understand how they affect vulnerable beaches. This issue is of particular concern in the Gulf of Mexico due to the presence of oil, natural gas, and plastic production. In this thesis, we expand upon existing Bayesian plastic attribution models and develop a rigorous statistical framework to map observed beached microplastics to their sources. Within this framework, we combine Lagrangian backtracking simulations of floating particles using nurdle beaching …

Development Of A Historic Digital Elevation Model (Hdem) From Archival Aerial Imagery Over The Black Mountain Alluvial Fan, Canada, Emma Menio

Graduate Theses and Dissertations

In a rapidly changing Arctic, reconstructing landscapes pre-warming is essential to understanding impacts due to climate-inducted geomorphic change. High-latitude elevation datasets extend temporally back to the 2000s, while region-wide warming became measurable in the 1980s. Historic aerial imagery archives provide datasets of high-resolution imagery from the mid- to late- 1900s with stereo-capability that can be harnessed to create historic digital elevation models, or hDEMs. A major issue with reconstructing a surface from the past is finding a way to constrain it in space, given a lack of ground control from that era, especially at high latitudes. The main purpose of …

Age, Size, And Composition Of Selected Old-Growth Shortleaf Pine Stands In The Upper Buffalo River, Arkansas, Willa Avery Thomason

Graduate Theses and Dissertations

Shortleaf pine (Pinus echinata) approaches the westernmost limits of its range in the Arkansas Ozarks. Despite heavy logging of shortleaf pine throughout its range during the 19th and 20th centuries, the species was not easily accessible for harvest and transportation in the most rugged areas of the Boston Mountains and, as a result, there are a few extant stands of old-growth shortleaf pine in the region. The shortleaf pine stands in the interior Boston Mountains are unusual in that they exist primarily above bluff lines at topographic breaks in the hardwood canopy and are not disturbed by fire as frequently …

Llm-Adapters: An Adapter Family For Parameter-Efficient Fine-Tuning Of Large Language Models, Zhiqiang Hu, Lei Wang, Yihuai Lan, Wanyu Xu, Ee-Peng Lim, Lidong Bing, Xing Xu, Soujanya Poria, Roy Ka-Wei Lee

Research Collection School Of Computing and Information Systems

The success of large language models (LLMs), like GPT-4 and ChatGPT, has led to the development of numerous cost-effective and accessible alternatives that are created by finetuning open-access LLMs with task-specific data (e.g., ChatDoctor) or instruction data (e.g., Alpaca). Among the various fine-tuning methods, adapter-based parameter-efficient fine-tuning (PEFT) is undoubtedly one of the most attractive topics, as it only requires fine-tuning a few external parameters instead of the entire LLMs while achieving comparable or even better performance. To enable further research on PEFT methods of LLMs, this paper presents LLMAdapters, an easy-to-use framework that integrates various adapters into LLMs and …

Unveiling Identity: Exploring Afrofuturism In Ekow Nimako’S Contemporary African Diasporic Sculptural Art, Kandra James

Theses

Identity expressed within African diasporic arts has historically been connected to traditional genres such as portraiture. Over time, contemporary artists have explored identity through genres beyond portraiture and through the use of non-traditional materials. The sculptural practice of Ghanaian Canadian artist Ekow Nimako, a fine arts sculptor based in Toronto, Canada, employs the unconventional material of LEGO® to offer a multi-generational perspective into deep diasporic memory. Examining Nimako’s sculptures through the perspective of colonialism and de-colonialism, materiality, and Afrofuturism, this thesis investigates the artist’s exploration of Black historical pasts to shape identities and construct narratives of Black futures. The monumental …

Suspended And Deposited Microplastics In The Coastal Atmosphere Of Southwest England, Giannis Kyriakoudes, Andrew Turner

School of Geography, Earth and Environmental Sciences

Atmospheric microplastics (MPs) have been sampled from coastal southwest England during twelve periods over a 42-day timeframe in late autumn. MPs were dominated by fibres, with foams, fragments and pellets also observed. The majority of fibres were identified as the semisynthetic polymer, rayon, while other shapes were dominated by various petroleum-based thermoplastics (including polyvinyl acetate, polyvinyl alcohol, polyamide and polyester) and paints. MP concentrations suspended in air ranged from 0.016 to 0.238 items per m3 but displayed no clear dependence on wind speed or direction. Total depositional fluxes ranged from 0.47 to 3.30 m−2 h−1 and showed no clear dependence …

"I Think There Is A Place For Small Programs:" Advocating, Implementing, And Sustaining Tpc Programs In Small Us Institutions, Martha Lynn Russell

English Theses & Dissertations

Technical and Professional Communication (TPC) programs in small institutions compose of over a third of all programs in the US, yet this space has been understudied by most scholars. To fill this gap, this dissertation presents findings from one-hour interviews with twenty-six TPC program directors in small US institutions with undergraduate populations of less than six thousand. The results of this dissertation include the ways that small institutions are advocating, implementing, and sustaining their TPC program in unique ways with implications for how any TPC programs regardless of size can learn from these findings.

Terror And Tenderness In Criminal Law, M. Eve Hanan

Cardozo Law Review

Sentencing reductions, executive pardons, prison release programs, and progressive prosecutors have something in common. In word choice and design, they suggest tempering the violence of criminal law in a limited number of cases. The prisoner may be released early based on a record of good behavior. The President may grant clemency to those sentenced in an earlier era to decades in prison for a drug crime. The prosecutor may recommend drug court rather than a jail sentence to a defendant addicted to illegal substances. In the era of “smart on crime,” reform often comes through expanding these mechanisms of relief …

Social Work And The Platform Economy: A Labor Process Theory Analysis, Lauri Goldkind, Barbara Pohl, Lea Wolf

Social Service Faculty Publications

Therapy is now available via digital platforms brokering relationships between practitioners and clients. Licensed clinical social workers contract with direct-to-consumer digital platforms to provide tele–mental health services. We employ labor process theory (LPT) to explore the interpersonal work of therapy as a labor arrangement, arguing that the core theory of LPT is useful for analyzing the overlapping clinical and material dynamics of conducting social work in online environments. We extend LPT analyses of gig work to the behavioral health field. Although platforms attract social workers by promising autonomy, the managerial controls that platforms exert and the emotional labor that social …

Human Trafficking In The Americas: Comparison Of Original Source Compilation Versus Unodc Data, Ivette Avila Jimenez

Electronic Theses, Projects, and Dissertations

International human trafficking (IHT) is a type of criminal activity that involves groups and individuals who facilitate the global movement and exploitation of people, often by illegal means. Estimates show that, worldwide, there are over 25 million victims of human trafficking at any given time; however, estimates are prone to under and overcounting. Focusing on the Americas, this study compared the quality of two data sources that could be used to observe IHT. Country-to-country IHT networks generated from 9 years of researcher compiled governmental and non-governmental data (2008-2017) was compared with networks generated from data downloaded from the United Nations …

“Yo Sí Soy Boricua, Pa’ Que Tú Lo Sepas”: A Decolonial And Intersectional Analysis Of Alexandria Ocasio-Cortez, Jocelin Monge

Electronic Theses, Projects, and Dissertations

Historically speaking, political representation in Congressional districts in the U.S. has been predominantly White and male. Alexandria Ocasio-Cortez (AOC) is an example of a type of new mestizaconsciousness (Anzaldúa, 1987) given she is the youngest Latina congresswoman ever been elected to serve New York’s 14th Congressional District. This study employs an intersectional analysis on AOC’s viral moments with ‘The Squad’, Puerto Rico, Vogue, and Met Gala. Through a theoretical lens composed of elements of intersectionality (Crenshaw, 1991) and mestiza consciousness (Anzaldúa, 1987), this study focuses on three significant recurrent themes found in AOC’s estilos de resistencia or sensibilities …

Diver Perceived Value And Satisfaction On The Mississippi Gulf Coast, Ka'lon Duncanson

Honors Theses

The Mississippi Gulf Coast is known for its coastal beauty and the tourism that comes from the recreational activities associated with the water. However, there appears to be an underserved segment of the tourism industry. The coast provides opportunities for local scuba divers to take part in a range of diving activities, but there is minimal support for this tourism activity in Mississippi. There is a need for greater understanding about what local divers value in their diving experiences and how this might lead to greater satisfaction with this activity. Along with overall perceived value, the argument is made that …

The principal limitations of the terms NAFLD and NASH are the reliance on exclusionary confounder terms and the use of potentially stigmatising language. This study set out to determine if content experts and patient advocates were in favor of a change in nomenclature and/or definition. A modified Delphi process was led by three large pan-national liver associations. The consensus was defined a priori as a supermajority (67%) vote. An independent committee of experts external to the nomenclature process made the final recommendation on the acronym and its diagnostic criteria. A total of 236 panelists from 56 countries participated in 4 …
