Clinical Practice Skills For Incorporating Animal-Assisted Therapy In Occupational Therapy, Erin Wilhelm

Occupational Therapy Doctoral Capstones

The aim of my capstone project was to advance the field of animal-assisted therapy (AAT) and promote the incorporation of AAT within occupational therapy (OT) services. Existing research notably supports the implementation of AAT in OT practice in many settings and for a wide variety of diagnoses to promote occupational performance, build therapeutic rapport, and encourage motivation and engagement in therapy, but stronger evidence is needed to promote the incorporation of AAT (Andreason et al., 2017; Fine et al., 2019b). Despite the growth of AAT over the past two decades, there are few resources tailored specifically to the implementation of …

Adolescent Well-Being And Exclusionary Discipline: A Resiliency Model, Rachel Ballard

All-Inclusive List of Electronic Theses and Dissertations

Adolescents, especially those with a mental illness, often behave in ways judged to be impulsive, overly emotional, and irresponsible (Gogtay et al., 2004; Lawrence et al., 2015; Tamnes et al., 2010). Many teen behaviors which concern adults can be related to underdeveloped skills or competencies, rate of brain development, or expressions of mental disorders (Casey et al., 2011; Serbin et al., 2011; Spear, 2000). Behaviors commonly associated with adolescence, such as impulsivity, risk-taking, and efforts to fit in with peers, are often seen as a serious threat to school harmony, learning, and student safety, necessitating a disciplinary response from school …

Food As A Literary Device In The Hunger Games: World Building, Characterization, And Plot Momentum, Linzee Mitchell

Tales Out Of School: Delineating Student Speech Protections For The Digital Age, Jason Zenor

The University of New Hampshire Law Review

The way students communicate has also changed greatly over the last generation, but in the first two decades of 21st Century, the U.S. Supreme Court had yet to answers questions about the extent of power for school administrators to control off-campus speech on digital technologies. Then in the case of Mahanoy Area School District v. B.L (2021) the U.S. Supreme Court finally answered this question by holding that administrators do have the ability to control off-campus speech. The Court did give some specific scenarios in which administrators had power to regulate off-campus, but it did not give a bright-line rule. …

Advances And Applications In Ultrasound-Switchable Fluorescence Imaging, Liqin Ren

Bioengineering Dissertations - Archive

Cancer diagnosis is a prerequisite for further medical therapy and treatment. Near-infrared (NIR) fluorescence imaging is a desirable modality without invasiveness and nonionizing radiation. However, fluorescence suffers from a strong light scattering in tissues, leading to a low spatial resolution and low sensitivity in centimeter-deep tissue (limited to several millimeters). To enhance spatial resolution and avoid the high scattering of conventional fluorescence imaging in deep tissue, ultrasound-switchable fluorescence (USF) imaging has emerged as a highly promising technique for biomedical imaging and research. The principle of improving spatial resolution in USF imaging is to confine the fluorescence emission from thermosensitive fluorophores …

Development Of Multiscale And Multidimensional Light Sheet Microscopy For Image-Based Modelling Of Organogenesis, Tanveer Ashwini Ashwini Teranikar

Bioengineering Dissertations - Archive

Behavioral analysis of individual cells, in the form of structural phenotypes arising in response to mechanical stimuli or genomic alterations as small molecule intermediates of disease, are instrumental for understanding organogenesis. In this regard, dynamic cell tracking or temporal changes in cell shape, area and size are vital for modelling tissue interactions. However, optical diffraction limits imposed by lenses, hinders high resolution volume reconstruction of microscale biological processes and subcellular organelles. Thereby, isotropic intensity is restricted to limited focal volumes, reducing imaging distance to less than 1 mm for high magnification. To combat this, Light Sheet Microscopes (LSM) have emerged …

Quantification Of Dynamic Changes Of Hemodynamic And Metabolic Responses To Brachial Artery Occlusion: A Broadband Near-Infrared Spectroscopy Study, Caroline Elizabeth Carter

My thesis is a tripartite investigation that weaves RIC, mitochondrial dynamics, and health disparities …

Formation And Morphological Changes Of Stress Actin Filaments In Adipose-Derived Stem Cells, Adam Priester

Bioengineering Theses - Archive

Adipose-Derived Stem Cells (ADSCs) are a sub-type of stem cell that can be collected and isolated from the adipose tissue. Adipogenesis describes the commitment and differentiation of stem cells, including ADSCs, toward the adipocyte lineage. While much research has been completed on this process in the long term (>2 weeks), morphological changes of adipogenesis during the early phase (<24 hours) are lacking in the literature and remain to be elucidated. The current study focuses on these changes in the early and later stages of adipogenesis using adipogenic differentiation factors and fluorescent imaging analyses. Quantifiable data on morphological changes during both phases can provide insight into how these changes affect later differentiation and lay the groundwork for additional research in this area. Using fluorescent image analysis, it was shown that the eccentricity of ADSCs, a measure of cellular circularity, decreases exponentially in the early phase of adipogenesis. In contrast, the cellular area appears to increase exponentially during the same early period. During the later stages of differentiation, it was shown that actin filament length decreases exponentially and the ratio of lipid to actin length increases exponentially, demonstrating that lipid accumulation outpaces actin filament shortening and increasing circularity during the later stages. These findings may be used in future studies to further define the role of actin filament-mediated morphological changes and mechanobiology during adipogenesis.

A 30-Year Dataset Of Co2 In Flowing Freshwaters In The United States, Timothy R. Toavs, Caleb T. Hasler, Cory D. Suski, Stephen R. Midway

Faculty Publications

Increasing atmospheric carbon dioxide (CO2) concentrations have been linked to effects in a wide range of ecosystems and organisms, with negative effects of elevated CO2 documented for marine organisms. Less is known about the dynamics of CO2 in freshwaters, but the potential exists for freshwater organisms to be challenged by elevated CO2. In flowing freshwaters CO2 exhibits more variability than in lakes or the ocean, yet spatiotemporally extensive direct measures of CO2 in freshwater are rare. However, CO2 can be estimated from pH, temperature, and alkalinity—commonly collected water quality metrics. We used data from the National Water Quality Monitoring Council …

The global COVID-19 pandemic resulted in many jurisdictions implementing orders restricting the movements of people to inhibit virus transmission, with recreational angling often either not permitted or access to fisheries and/or related infrastructure being prevented. Following the lifting of restrictions, initial angler surveys and licence sales suggested increased participation and effort, and altered angler demographics, but with evidence remaining limited. Here, we overcome this evidence gap by identifying temporal changes in angling interest, licence sales, and angling effort in world regions by comparing data in the ‘pre-pandemic’ (up to and including 2019); ‘acute pandemic’ (2020) and ‘COVID-acclimated’ (2021) periods. We …

Atmospheric Flash Drought In The Caribbean, Craig A. Ramseyer, Paul W. Miller

Faculty Publications

Despite the intensifying interest in flash drought both within the United States and globally, moist tropical landscapes have largely escaped the attention of the flash drought community. Because these ecozones are acclimatized to receiving regular, near-daily precipitation, they are especially vulnerable to rapid-drying events. This is particularly true within the Caribbean Sea basin where numerous small islands lack the surface and groundwater resources to cope with swiftly developing drought conditions. This study fills the tropical flash drought gap by examining the pervasiveness of flash drought across the pan-Caribbean region using a recently proposed criterion based on the evaporative demand drought …

Soil Legacy Nutrients Contribute To The Decreasing Stoichiometric Ratio Of N And P Loading From The Mississippi River Basin, Zihao Bian, Hanqin Tian, Shufen Pan, Hao Shi, Chaoqun Lu, Christopher Anderson, Wei Jun Cai, Charles S. Hopkinson, Dubravko Justic, Latif Kalin, Steven Lohrenz, Steven Mcnulty, Naiqing Pan, Ge Sun, Zhuonan Wang, Yuanzhi Yao, Yongfa You

Faculty Publications

Human-induced nitrogen–phosphorus (N, P) imbalance in terrestrial ecosystems can lead to disproportionate N and P loading to aquatic ecosystems, subsequently shifting the elemental ratio in estuaries and coastal oceans and impacting both the structure and functioning of aquatic ecosystems. The N:P ratio of nutrient loading to the Gulf of Mexico from the Mississippi River Basin increased before the late 1980s driven by the enhanced usage of N fertilizer over P fertilizer, whereafter the N:P loading ratio started to decrease although the N:P ratio of fertilizer application did not exhibit a similar trend. Here, we hypothesize that different release rates of …
