Influence Of Physiochemical And Watershed Characteristics On Mercury Concentration In Walleye, Sander Vitreus, M., Cari-Ann Hayer, Steven R. Chipps, J. J. Stone

Natural Resource Management Faculty Publications

Elevated mercury concentration has been documented in a variety of fish and is a growing concern for human consumption. Here, we explore the influence of physiochemical and watershed attributes on mercury concentration in walleye (Sander vitreus, M.) from natural, glacial lakes in South Dakota. Regression analysis showed that water quality attributes were poor predictors of walleye mercury concentration (R² = 0.57, p = 0.13). In contrast, models based on watershed features (e.g., lake level changes, watershed slope, agricultural land, wetlands) and local habitat features (i.e., substrate composition, maximum lake depth) explained 81% (p = 0.001) …

Corn Hybrids: Deer Taste The Difference, Joshua A. Delger, Kevin L. Monteith, Jonathan A. Jenks

Natural Resource Management Faculty Publications

As daylight begins to illuminate the countryside, a cold wind rustles through the leaves of the weedy rows of corn that you barely had time to get in the ground this past spring. The corn plants are stunted, the few small ears of corn that did grow are not even enticing to passing blackbirds, and that stud buck captured on your trail-camera months earlier is nowhere to be seen. Meanwhile, a couple hundred yards across the fence to the south, you hear the unmistakable sound of deer running through corn. Your heart rate involuntarily increases. As the sun continues to …

The Objects Of The Whites: Commodities And Consumerism Among The Xikrin-Kayapó (Mebengokre) Of Amazonia, Cesar Gordon

Tipití: Journal of the Society for the Anthropology of Lowland South America

In this paper I discuss the recent phenomenon of conspicuous and increasing consumption of goods among the Xikrin-Kayapó (Mebengokre) of Pará, Brazil. Money and goods have become embedded in every domain of Xikrin life, including kinship, economy, politics and ritual. Merchandise can now be seen as a total social fact in Xikrin‑Kayapó society. I show that this sort of consumerism results from a complex interaction between general principles of Mebengokre sociocosmology and the particular historical conditions in which such principles operate and are actualized. In particular, I suggest that the meaning and function of manufactured goods and money (“Whites’ stuff,” …

Computational Mirna Target Prediction In Animals, Leyan Tang

Master's Projects

miRNAs are a class of small RNA molecules about 22 nucleotides long that regulate gene expression at the post-transcriptional level. The discovery of the second miRNA 10 years ago was as much a surprise in its own way as the very structure of DNA discovered a half century earlier[1]. How could these small molecules regulate so many genes? During the past decade the complex cascade of regulation has been investigated and reported in detail[2]. The regions of the genome called untranslated regions, or UTRs, proved true to their name: they were indeed untranslated, but certainly not unimportant: they act as …

A Microrna Target Prediction Algorithm, Rupinder Singh

Master's Projects

MicroRNA target prediction using the experimental methods is a challenging task. To accelerate the process of miRNA target validation, many computational methods are used. Computational methods yield many potential candidates for experimental validation. This project is about developing a new computational method using dynamic programming to predict miRNA targets with more accuracy. The project discusses the currently available computational methods and develops a new algorithm using the currently available knowledge about miRNA interactions.

Reconsidering Federalism And The Farm: Toward Including Local, State And Regional Voices In America's Food System, Margaret Sova Mccabe

Journal of Food Law & Policy

Why is the relationship between our food system and federalism important to American law and health? It is important simply because federal law controls the American food system. This essay considers how federal law came to structure our food system, and suggests that though food is an essential part of our national economy, the dominating role of the federal government alienates citizens from their food system. It does so by characterizing food as a primarily economic issue, rather than one that has ethical, health, and cultural components. However, state and local governments have much to offer in terms of broadening …

Treatment Of Severe Aortic Stenosis : Experimental Design, Testing, And Analysis Of An Aortic Valve Bypass Apical Cannula., Joel Douglas Graham

Electronic Theses and Dissertations

Aortic Valve Bypass surgery has found renewed interest to researchers due to its application in high-risk patients with severe aortic stenosis. This therapy consists of construction of a conduit containing a bioprosthetic or mechanical valve from the apex of the left ventricle to the descending thoracic aorta. Blood is ejected from the left ventricle via both the native stenotic aortic valve and the conduit. This thesis proposes a design for one of the least developed components of this system, the cannula component that sits inside the left ventricle and allows for flow of blood from the left ventricle and into …

Blanchot And Ambiguity, Paolo Bartoloni

CLCWeb: Comparative Literature and Culture

In his article "Blanchot and Ambiguity" Paolo Bartoloni investigates the enigmatic and ambiguous turn of the famous Blanchotian statement "existence without Being." The intention of the article is to locate Blanchot's remark in the context of a discussion on history and its possible end, famously initiated by Alexandre Kojève in a lecture on 4 December 1937 at the College of Sociology in Paris; and provide insights into the difference that distinguishes Kojève's reflection on the end of history, Bataille's subsequent interpretation of it, and Blanchot's original conceptualization of a state of being suspended between nature and culture, history and the …

Ambiguity, The Artist, The Masses, And The "Double Nature" Of Language, Elizabeth Rechniewski

CLCWeb: Comparative Literature and Culture

In her article "Ambiguity, the Artist, the Masses, and the 'Double Nature' of Language" Elizabeth Rechniewski discusses the function of the European intellectual elite through a close reading of two very different yet related books, John Carey's The Intellectuals and the Masses, and Pierre Bourdieu's Les Règles de l'art. Through a contrapuntal reading of the arguments of these two critics, she argues that Symbolist experiments may actually be read as reactionist; in celebrating art's supposed conquest of independence and refinement, they are replete with nostalgia for a time when the artist and the intellectual were able to ignore the pressure …

Establishment Of Permanent Plots And Analysis Of Woody Vegetation In The Tennessee River Gorge, Marion And Hamilton Counties, Tennessee, Gerald Woodworth

Masters Theses and Doctoral Dissertations

The Tennessee River Gorge (TRG) is a large river canyon 8 km west of Chattanooga, Tennessee, on the Cumberland Plateau. In 1984, the Tennessee Natural Heritage Program (TNHP) described 21 vegetation communities within the TRG. Permanent vegetation plots for the long-term study of 13 of these communities were established in summer 2009 in order to fulfill three goals. The first goal was to provide baseline data for long-term monitoring through establishing and surveying 100 plots. The second goal was to perform a temporal comparison of each community to its original description from 1984. The third goal was performing a comparison …

Case Jp: Twenty Experiments On A Person With Congenital Prosopagnosia And Inability To Experience Visual Imagery From Birth, Leanne Walker

The Plymouth Student Scientist

Congenital Prosopagnosia and inability to experience visual imagery was investigated through administration of neuropsychological, face processing and visual imagery tests on a single patient, JP. JP had no general intellectual impairment, no problems affecting visual and spatial abilities and had little problems affecting overall memory. She was impaired on unfamiliar face matching, perception of eye gaze and famous face recognition, and was in the normal range for facial expression recognition; thus suggesting that JP is of the “prosopagnosic” type. Subjective vividness and spontaneous use of imagery was rated as extremely poor and performance of standard tests of visual imagery yielded …

An Investigation Of The Risks For Human Health From Bio-Available And Bio-Accessible Arsenic In The Tamar Catchment Using Human Hair Bio-Markers And Geochemical Data, Richard Cattan

The Plymouth Student Scientist

Geologic mineralisation and anthropogenic exploitation in the Tamar catchment of south-west England have resulted in an environment enriched with arsenic, a recognised carcinogen and systemic toxicant that can target many organs in the human body. This study examined geochemical data from the catchment and found particularly high arsenic contamination around the historic mining districts of Callington and Gunnislake, where maximum concentrations of 39 µg L-1 in stream waters, 11000 mg kg-1 in stream sediments, and 15000 mg kg-1 in topsoils were found in certain areas. Hair samples from 91 catchment residents were analysed using inductively-coupled plasma mass spectrometry. The arsenic …

The Effect Of Forest Edges On The Community Structure Of Tropical Fruit-Feeding Butterflies, Claire Armstrong

The Plymouth Student Scientist

Artificial edges in tropical forests are known to have profound effects on microclimate, tree mortality, forest structure, and community composition. While edges between continuous forest and clear felled stands have been well-researched, less attention has been paid to the effects of logging roads and smaller tracks. This study focuses on the effect a small (2-3m wide) road has on the community structure of the guild of fruit-feeding Nymphalidae butterflies in Sabah, Borneo. Traps were hung at ground-level along the road and 100m into the adjacent primary forest. In total, 43 individuals from 17 species were caught. Both the edge and …

The Therapeutic Effects Of Working With Dartmoor Ponies: A Pathfinding Project, Dawn Chaplin

The Plymouth Student Scientist

The area of Animal Assisted Therapy, and in particular therapy with Equines, was investigated to assess whether this sort of therapy could contribute to Social and Emotional Aspects of Learning (SEAL). It was proposed that quantitative and qualitative measures would suggest an increase in social and emotional functioning following an Equine Facilitated Learning (EFL) intervention. Three ‘at-risk’ adolescent males were nominated by teaching staff to participate in a quasi-experimental research design, whereby measures were taken but no variables manipulated. Quantitative data provided weak support for the hypothesis although qualitative data suggested an improvement in functioning followed by a decline in …

Beneficial Roles Of Microorganisms In The Coral Reef Ecosystem, Katie R. Laming

The Plymouth Student Scientist

Coral reef biodiversity has declined over the past few decades and despite recent significant scientific interest in reefs in light of noticeable effects of climate change on this fragile habitat there is still much undiscovered about the true diversity of the symbiont community. There is also much to ascertain about underlying holobiont mechanisms relating to beneficial properties resident bacteria possess to help their hosts defend themselves from pathogenic xenobacteria or how symbionts provide the holobiont and other reef organisms with nutrition by utilising the carbon and nitrogen cycles. These are some of the questions addressed in this literature review. It …

Regulation Of Biofilm And Antibiotic-Resistance By The Modulator Of Sara (Msa) In Staphylococcus Aureus, Antony Schwartz

Dissertations

Staphylococcus aureus is an important human pathogen that is the causative agent of life-threatening diseases such as endocarditis and osteomyelitis. The ability of S. aureus to thrive as a successful pathogen can be partially attributed to its ability to form biofilm. Biofilm is an extracellular polysaccharide, protein, and DNA-based slime layer that protects the bacterial community. The global regulator sarA is essential for biofilm formation. Since the modulator of sarA (msa) gene regulates several virulence factors and is required for the full expression of sarA, the capacity of the msa mutant to form a biofilm was examined. The mutation of …

The project focuses on the life cycle of development, functional annotation, and utilization of genomic tools for the avian wildlife species to determine the molecular impacts of exposure to munitions …

Life History And Habitat Use Of The Juvenile Alabama Shad (Alosa Alabamae) In Northern Gulf Of Mexico Rivers, Paul Fraser Mickle

Dissertations

The Alabama shad, Alosa alabamae, is an anadromous species that is in decline and has seen extirpations from impoundments as well as decreased water quality. Alabama shad live in the Gulf of Mexico and ascend Northern Gulf of Mexico Drainages to reproduce early in the year (January-May). The juveniles spend the majority of the year in these freshwater systems before emigrating out to the Gulf of Mexico as late as December.

This dissertation focuses on the juvenile life stages that occur within the Northern Gulf of Mexico drainages. Spawning conditions of the river, as well as the habitat and diet, …

A Psychometric Investigation Of The Young Adult Social Behavior Scale (Yasb), Michelle Rene Augustin

Dissertations

Aggressive behavior is a serious public health concern that has resulted in several problems in contemporary society. Despite a considerable body of literature on human aggression, both popular and scientific, a focus on overt physical aggression has obscured other forms of aggression. As a result, considerably less is known about other, more subtle forms of aggression, such as relational aggression. Moreover, research on relational aggression, particularly among older adolescents and adults, has been hindered by the lack of psychometrically sound measures. Research in this area would be enhanced by the availability of such a measure, facilitating comparison of data across …
