Exploring Nature-Based And Animal-Assisted Therapies As A Therapeutic Modality, Rachel Cheatley Jan 2023

Exploring Nature-Based And Animal-Assisted Therapies As A Therapeutic Modality, Rachel Cheatley

Occupational Therapy Capstones

Animal-assisted therapy (AAT) is characterized by integrating animals into the therapy process as a therapeutic partner and modality (Laskowski et. al., 2019). AAT shows positive outcomes for those who take part in the practice (Ein et. al., 2018; Feng et. al., 2021; Mapes & Rosén, 2016; Nieforth et. al., 2021). Common goals that are targeted via AAT include anxiety and related symptoms, depression and related symptoms, coordination, fine motor skills, reaching, hand-eye coordination, body balance, body awareness, communication, and relationship building (Ein et. al., 2018; Feng et. al., 2021; Mapes & Rosén, 2016; Nieforth et. al., 2021). Even with the …

A Guide For Occupational Therapists: Utilizing Equine-Assisted Therapy For Children In The Foster Care System Dealing With Trauma, Alexis Skogen Jan 2023

A Guide For Occupational Therapists: Utilizing Equine-Assisted Therapy For Children In The Foster Care System Dealing With Trauma, Alexis Skogen

Occupational Therapy Capstones

In 2015, over three million children who were affected by trauma or abuse were reported to Child Protective Services (Papovich, 2019). “Children in the foster care system have often been exposed to traumatic experiences such as violence, illicit substances, and neglect” (Crabill & Hanson, 2018, p.8). Adverse childhood experiences (ACEs) can be similar to experiencing trauma; children, prior to entering the foster care system, often experience ACEs (Craig, 2020). Children in the foster care system face hardships such as being taken out of their homes, passing through multiple homes, in addition to other childhood traumas they experience prior to their …

Radiology departments have contributed significantly to greenhouse gases including release of toxic imaging contrast media to environment. We feel Radiology also has several spectroscopy and imaging tools that may apply to monitor and support cleaner environmental goals. The current manuscript is one of the firsts to prompt Radiology to move in that direction by non invasive imaging of bio metals that are less abundant in biological tissues but play key roles as co-factors in tissue structure and function. Conventional analytical tools are mostly invasive and cannot characterize the native oxidation states of bio metals. We chose carbohydrate matrix of metal-rich …

Climate Change And Modern State Common Law Nuisance And Trespass Tort Claims, Jack Wold-Mcgimsey Jan 2023

Climate Change And Modern State Common Law Nuisance And Trespass Tort Claims, Jack Wold-Mcgimsey

University of Colorado Law Review

This Comment examines the use of state common law tort claims to address climate change. The aim of this work is not to provide an in-depth examination of these issues, but rather to provide a contextualized and comprehensive overview of some of the most important issues in this field using modern cases actively being litigated. This Comment comes to the conclusion that the future of common law nuisance and trespass claims in the context of climate change is, for now, unclear. Given the national and global implications of climate change, courts may find that isolated states cannot set binding precedents …


Producing Procedural Inequality Through The Empirical Turn, Danya Shocair Reda Jan 2023

Producing Procedural Inequality Through The Empirical Turn, Danya Shocair Reda

University of Colorado Law Review

Procedural rulemaking and scholarship have taken an empirical turn in the past three decades. This empirical turn reflects a surprising consensus in what is otherwise a highly divided field and an inherently adversarial system. Because procedural rules distribute legal power in society, they invariably raise questions about who should have access to courts, information, and the means to defend one's legal rights. While debate rages about these normative commitments, procedure has developed a surprising epistemic agreement on empiricism, with its promise of rising above these competing interests with data. In procedure, the turn toward empiricism has become a strategy for …

School of Geography, Earth and Environmental Sciences

Little information exists on the fate and impacts of boats constructed of fibreglass reinforced plastic (FRP) once they reach their end-of-life. In this study, the number of abandoned fishing boats constructed of FRP or constructed of plywood-wood and sheathed by FRP has been determined along the coast of Kerala, India, and chemical emissions have been estimated when boats are burned as a means of disposal. A total of 292 abandoned boats were observed across eight coastal transects constructed around selected landing centres, with abandonment ranging from 13 to 48 per km (average = 29 km−1). This results in the generation …

This project began with a survey distributed to 7 infant and toddler classroom educators, after which responses were analyzed for themes regarding perceived infant interests. Subsequent observations were conducted to evaluate the best fit for the implementation of an outdoor experiential music space. Based on the findings, a developmentally appropriate …


Alexander Von Humboldt: Explorer, Naturalist, And Environmental Pioneer (2019) By Danica Novgorodoff, Peter Shea Jan 2023

Alexander Von Humboldt: Explorer, Naturalist, And Environmental Pioneer (2019) By Danica Novgorodoff, Peter Shea

Picture Books

As a young boy, Alexander Von Humboldt came up with divergent questions about the birds and mountains and animals he saw, and brought all those questions together under two big questions that stayed important for him over a long life: “How are these things different?” and “How are they nevertheless connected?” As the reader watches Humboldt looking at a hawk and a mouse, volcanoes and farmland, palm trees and pine trees, Europe and Ecuador, Europeans and Indigenous people, one comes to expect what he will say: “They are different, and yet they are connected.” This idea is much bigger than …


Assessment Of The Triple Reuptake Inhibitor Diclofensine: Effort-Based Decision-Making In A Rodent Model Of Motivational Dysfunction, Sofia Papanikolaou Jan 2023

Assessment Of The Triple Reuptake Inhibitor Diclofensine: Effort-Based Decision-Making In A Rodent Model Of Motivational Dysfunction, Sofia Papanikolaou

Holster Scholar Projects

Serotonin-selective reuptake inhibitors (SSRIs) are the most commonly prescribed antidepressant medications. Despite their popularity, they remain relatively ineffective at treating effort-related motivational symptoms of depression such as fatigue and anergia. Increasing research on triple reuptake inhibitors (TRIs) that target three neurotransmitters—dopamine, serotonin, and norepinephrine—has suggested that TRIs could have efficacy in targeting motivational dysfunction due to their dopaminergic effects. Previous research has shown that the dopamine depleting agent tetrabenazine can reliably induce motivational deficits in rats, as evidenced by a shift towards low-effort behavior in effort-based choice tasks, and provide a validated approach to creating a model of motivational dysfunction. …


Least Flycatchers Under-Reported In Fall Migration In Arkansas —A Citizen Science Conundrum, L. Barnes, R. Kannan Jan 2023

Least Flycatchers Under-Reported In Fall Migration In Arkansas —A Citizen Science Conundrum, L. Barnes, R. Kannan

Journal of the Arkansas Academy of Science

The Least Flycatcher Empidonax minimus is a small passerine migrant bird that passes through Arkansas in fall and spring migration. The birds are vocal during spring passage but relatively quiet and unobtrusive during fall migration, leading to many fewer reports by birdwatchers in fall than spring. We use eBird maps and data to present evidence to support this discrepancy between fall and spring observations. We also show that the species is under-reported in Arkansas during the fall compared to neighboring regions. This may be in part due to the reluctance of some birders to provide the minimal evidence required to …

Energy Content Of Grasshoppers (Orthoptera: Acrididae) In The Diet Of Scaled Quail (Callipepla Squamata) In Southeastern New Mexico, J.L. Hunt, M.E. Grilliot, T.L. Best, C.M. Wilkerson, A.F. Huitt

Journal of the Arkansas Academy of Science

Grasshoppers (Orthoptera: Acrididae) are common insects that are important food items for many kinds of wildlife, including many species of upland game birds such as scaled quail (Callipepla squamata). We analyzed the energy content of grasshoppers obtained from the crops of scaled quail collected from plainsmesa sand-scrub in Lea and Eddy counties, New Mexico. Grasshoppers were removed from crops and dried for 48 hours at 60°C to remove moisture and standardize masses. Grasshoppers were then pulverized and analyzed for gross caloric value (i.e., energy content) in an oxygen bomb calorimeter. Energy content of grasshoppers from New Mexico averaged 19.2 J/kg …


Validation Of A Diagnostic Marker For Primocane-Fruiting In Blackberry, Isabella Vaughn, Alexander Silva, Carmen Johns, Lacy Nelson, Margaret Worthington Jan 2023

Validation Of A Diagnostic Marker For Primocane-Fruiting In Blackberry, Isabella Vaughn, Alexander Silva, Carmen Johns, Lacy Nelson, Margaret Worthington

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Typical blackberries (Rubus subgenus Rubus) have perennial crowns and roots and biennial canes. The first-year canes (primocanes) are usually vegetative, while second-year canes (floricanes) produce fruit. Primocane-fruiting blackberries produce fruit on first-year canes and are desirable to growers because they potentially allow for a longer harvest season in temperate regions and enable production in tropical areas where no natural chill hours are accumulated. The development of molecular markers for desirable traits can potentially increase efficiency in blackberry breeding. However, to date, there are no diagnostic molecular markers for economically important traits in blackberries. Primocane-fruiting is recessively inherited, and tetraploid blackberries …

Location Of The Fibronectin Binding Domain On The Fibronectin Attachment Protein Of Mycobacterium Avium Subsp. Paratuberculosis, Chrissy Rose Hattery

All Graduate Theses, Dissertations, and Other Capstone Projects

Mycobacterium avium paratuberculosis (MAP) is an acid-fast bacillus that causes a fatal granulomatous ileocolitis called Johne’s Disease that affects primarily ruminants. The impact of MAP infection in the US dairy industry is particularly severe, with up to 70.4% of the herds being infected and annual losses as high as $1.5 billion. MAP is capable of persisting for months in the livestock environment and surviving the pasteurization process. While several vaccines are available, none can prevent infection and treatment with antimycobacterial chemotherapy does not result in a cure. Management and control of MAP infection requires characterization of host-pathogen interaction at the …

Novel Amino Acids Dictate Differences In Sivmac239 And Hiv-2 Rod9 Vpx Cellular Localization, Hunter D. Mayhew Jan 2023

Novel Amino Acids Dictate Differences In Sivmac239 And Hiv-2 Rod9 Vpx Cellular Localization, Hunter D. Mayhew

All Graduate Theses, Dissertations, and Other Capstone Projects

Vpx is a protein encoded by Human Immunodeficiency Virus Type 2 (HIV-2) and specific Simian Immunodeficiency Viruses (SIVs) that is essential for successful infection of non-dividing myeloid cells. Vpx facilitates viral replication by trafficking the viral genome into the nucleus of infected cells and targeting the primarily nuclear innate immune protein SAMHD1 for proteasomal degradation. Considering that these activities occur at the nucleus, we hypothesized that Vpx nuclear localization would be tightly correlated with these functions. To assess this, site directed mutagenesis in combination with confocal microscopy or Western Blotting analyses were utilized to evaluate the determinants of nuclear accumulation …


An Archeozoological Analysis Of The Vosburg Site In Southern Minnesota, Madison M. Rutter Jan 2023

An Archeozoological Analysis Of The Vosburg Site In Southern Minnesota, Madison M. Rutter

All Graduate Theses, Dissertations, and Other Capstone Projects

The Blue Earth Oneota is a poorly defined taxon located in southern Minnesota. Few large-scale excavations have been conducted in the Blue Earth region, leading to gaps in the overall understating of western Oneota lifeway systems. This research utilizes archeozoological analysis on the zoological assemblage from the Vosburg site (21FA02), a Blue Earth Oneota site located in Faribault County. The Vosburg site is a large habitation site that has been excavated by Wilford in 1938 and 1947, Dobbs in 1979, and Schirmer in 2012. Legacy data from the 1938, 1947, and 1979 excavations was analyzed and compared to the zoological …

All Graduate Theses, Dissertations, and Other Capstone Projects

Through the analysis of pottery remains found at the Eleanor archaeological site, the study investigates the relationship between the Fox Lake culture and the Havanoid phases. The relationship between the Fox Lake complex of the southwestern prairie area and the Havanoid phases of the eastern woodlands is poorly understood in southern Minnesota. Despite it is potential to provide information about this relationship, the Eleanor site (21NL30) collection was never thoroughly studied after the excavation.

Richard Strachan conducted excavations at the Eleanor site between 1976 and 1978. A total of 124 pottery sherds were examined, with 76 being rim sherds and …


The Role Of Insulin-Like Growth Factor I In The Development Of The Cerebellum In Euthyroid And Hypothyroid Mice, Prathibha Mangedarage Jan 2023

The Role Of Insulin-Like Growth Factor I In The Development Of The Cerebellum In Euthyroid And Hypothyroid Mice, Prathibha Mangedarage

All Graduate Theses, Dissertations, and Other Capstone Projects

Thyroid hormone deficiency during development is known to cause anatomical defects in the cerebellum that lead to neurological deficits. It has been observed that insufficient thyroid hormone levels also decrease the levels of brain derived Insulin-like growth factor 1 (Igf-1). Given that the deficits caused by low Igf-1 levels are similar to those caused by low thyroid hormone, we designed this study to investigate if the deficits caused in the development of the cerebellum by low thyroid hormone levels may be due to the lack of sufficient Igf-1. We also sought to determine if ectopic over expression of Igf-1 in …

Revisiting The Blue Earth Oneota Taxon, Samuel Marcucci

All Graduate Theses, Dissertations, and Other Capstone Projects

Clark Dobbs’ 1984 dissertation on Blue Earth Oneota settlement patterns is often the go-to treatment for the Blue Earth taxon. Since the publication of his work, new methods of archeological research have been employed within the field and new data have been uncovered from both Blue Earth sites in Minnesota and Oneota sites throughout the Midwest. This thesis attempts to ask if the modern archeology of Blue Earth Oneota is still comprehended by Dobbs’ 1984 publication. Feature analysis of material recovered from refuse pit features during the 2012 excavation at the Vosburg site (21FA02) was utilized in this research along …


Investigation Of Glycoside Hydrolases And Calcium In Cytophaga Hutchinsonii Cellulose Utilization, Choua Kou Vang Jan 2023

Investigation Of Glycoside Hydrolases And Calcium In Cytophaga Hutchinsonii Cellulose Utilization, Choua Kou Vang

All Graduate Theses, Dissertations, and Other Capstone Projects

Cytophaga hutchinsonii is a soil bacterium that can utilize cellulose as a carbon source. The cellulose utilization system of C. hutchinsonii has been predicted to be novel and its endoglucanases could potentially be used in the production of cellulosic based biofuels. These enzymes could be used to process cellulose to glucose or other soluble sugars, which can be further converted to ethanol by yeast fermentation. Current biofuels utilize starches, primarily from corn, which has direct competition with farming space for food crops. This study focuses on observing the growth of C. hutchinsonii knockout mutant strains on cellulose substrate to better …
