Implications Of Embodied Cognition And Schema Theory For Discerning Potential Meanings Of Improvised Rhythm, James Hiller

Books and Book Chapters by University of Dayton Faculty

Rhythm is an essential and therefore indispensable aspect of all music. Arguably, rhythmic elements are the most accessible of all the musical elements for clients in music therapy to produce and manipulate expressively (Hiller, 2011). Yet, theoretical understanding of rhythm and its use in musical expression is a neglected area of both music therapy (Bunt, 1994; Daveson & Skewes, 2002) and musicological inquiry (Gabrielsson, 1993; Kramer, 1988; Mead, 1999). However, the area of psychological investigation known as “embodied cognition” or “schema theory,” which has been constructively applied to composed tonal music, may prove fruitful in deepening our understanding of potential …

The Secular And Religious Legal Framework Of Afghanistan As Compared To Western Notions Of Equal Protection And Human Rights Treaties: Is Afghanistan's Legal Code Facially Consistent With Sex Equality?, Laura Belkner

Cardozo Journal of International and Comparative Law

The note examines Afghanistan's legal framework, arguing that while it is facially consistent with sex equality as per the Afghan Constitution and international treaties, the practical implementation is hindered by cultural and traditional practices. This discrepancy highlights the gap between legal provisions and real-world application.

Monitoring Occupancy And Abundance Of New England Cottontails Using Non-Invasive Genetic Tools, Daniel Brubaker

Master's Theses and Capstones

The New England cottontail (Sylvilagus transitionalis ) is a species of conservation concern. Efficient monitoring methods are needed to guide and assess conservation decisions in an adaptive management framework. I used genetic tools and non-invasively collected fecal DNA to determine New England cottontail detection rates during presence/absence surveys and to identify the environmental and behavioral factors that influence detection.

I found New England cottontail detection rates to be high (>90%) when surveys were conducted under ideal conditions. Prior knowledge of cottontail activity, low snow depth, and allowing 2-4 days without high winds following a snowfall are the most important …

Energy From Olive Mill Waste: Pyrolysis And Oxidation Kinetics Of Olive Mill Waste, Li Buessing

Master's Theses and Capstones

This study investigates the utilization of the olive mill waste stream before and after the removal of entrained phenolic compounds. The kinetics of pyrolysis and oxidation were analyzed via thermogravimetric analysis. Particle size, heating rate, and extraction process of the phenolic compounds affected the apparent activation energies. The pits and pulp in the olive mill waste had apparent activation energies ranging for pyrolysis from 91-137 kJ/mol and 72-87 kJ/mol, respectively. The analysis of the oxidation of olive mill waste was divided into two distinct zones: the devolatilization and oxidation of volatiles zone and the char oxidation zone. The oxidation had …

Development And Evaluation Of Interspecific Cucurbita Maxima X Cucurbita Moschata Hybrids For Processing Squash, Jacob Uretsky

Master's Theses and Capstones

Interspecific hybrids derived from crosses of Cucurbita maxima Duch. x C. moschata Duch. have been utilized for taxonomic studies and introgression of advantageous traits, as well as for cultivation for fresh market squash. The present study involves the development and evaluation of C. maxima x C. moschata F1 hybrids for use as processing squash. Crosses were performed in the summers of 2009, 2010, and 2011 between inbred bush C. maxima breeding lines and vine C. moschata cultigens, and the resulting progeny were evaluated in the greenhouse and field in 2010 and 2011 for phenological growth traits, fruit traits, and fruit …

Detection Of Trehalose In Porphyra Extracts Using Mass Spectrometry And Gas Chromatography-Mass Spectrometry, Ying Huo

Master's Theses and Capstones

It is known that trehalose helps many plants to survive under desiccated environment26. This property of trehalose has also been proposed to explain why Porphyra could survive desiccation when left on dry land for a long period of time25. However, after extensive study25, effort at identifying trehalose in Porphyra has been unsuccessful, leaving the question of whether trehalose really exists in Porphyra unanswered. In my thesis research, in collaboration with Dr. Anita Klein, I set out to use ion-trap mass spectrometry and gas chromatography coupled with mass spectrometry to identify and quantify the amount of trehalose in Porphyra extracts. Using …

A Comparison Of Bobcat (Lynx Rufus) Habitat Suitability Models Derived From Radio Telemetry And Incidental Observations, Derek Ja Broman

Master's Theses and Capstones

Habitat suitability models derived from data obtained from radio telemetry and citizen observations were developed to evaluate habitat selection of monitored bobcats, compare statewide habitat suitability models and maps developed using locations from telemetry and citizen observations, and produce statewide population estimates. In the winter of 2009-2010, adult bobcats were captured in southwest New Hampshire and equipped with GPS tracking collars. GPS locations were used to calculate home ranges and to build habitat suitability models using resource selection functions (RSF) following a used vs. available design. RSFs were also applied to recent reported statewide sightings. Comparisons between these two approaches …

Effects Of Whole-Tree Harvesting On Site Productivity And Species Composition Of A Northern Hardwood Forest, Gabriel Ethan Roxby

Master's Theses and Capstones

Whole-tree harvesting is widely used in the northeastern United States to supply biomass energy plants with fuel, but questions remain regarding its long-term sustainability. To assess its effects on the northern hardwood forests that make up a significant portion of northern New England, we conducted two regeneration surveys in 2010 and 2011 covering thirty-three small clearcuts. We measured whole-tree (WTH) and conventionally harvested (CH) sites in New Hampshire and Maine, and compared the productivity and species composition of the 10-14 year old regeneration. No significant difference was observed in height, diameter or calculated biomass of stems > 2m in height. Despite …

Field And Laboratory Observations Of Two Gulf Of Maine Sacoglossans, Seth W. Goodnight

Master's Theses and Capstones

The ecology of the sacoglossan Alderia modesta and its ability to retain active chloroplasts from the yellow-green alga Vaucheria spp. was examined with field and laboratory studies. Field surveys found no A. modesta, because Vaucheria spp. was absent or sparse in surveyed marshes. A grass removal experiment tested whether interspecific competition was causing the algal absence. The alga appeared in some plots, but did not promote A. modesta settlement. Absence of Vaucheria spp. is likely due to factors other than competition. Lack of animals prevented laboratory studies.

Placida dendritica and its food Codium fragile ssp. fragile were then chosen for …

Cryopreservation Spermiation Induction And Computer Assisted Analysis Of Summer Flounder (Paralicthys Dentatus) Spermatozoa, Ryan T. Brown

Master's Theses and Capstones

The objective of this thesis was to improve the aquaculture practices for summer flounder Paralichthys dentatus. The experiments in this thesis examined male reproduction. First a practical method for summer flounder sperm cryopreservation was developed. These experiments examined the various parameters required to successfully freeze and store summer flounder spermatozoa. Success of cryopreservation was measured by examining post thaw viability and fertility.

One of the problems facing summer flounder aquaculture is sexually dimorphic growth rates, with females growing larger than males. To overcome this, meiogynogenetic summer flounder were developed, allowing the production of all female stocks. The second set of …

A Comparison Of Standard And Ventless American Lobster Trap Dynamics, Abigail S. Clark

Master's Theses and Capstones

The American lobster, Homarus americanus, is the most valuable marine resource in New England and, as with any fishery, effective management depends on accurate stock assessment. The purpose of this study was to examine the efficacy of standard and ventless traps, focusing on determining which trap provides a better index of lobster abundance. While ventless traps caught approximately five times as many lobsters as standard traps, the size of captured lobsters did not differ significantly between trap types. Ventless traps saturated after 16 - 24 hours, but standard traps did not saturate at all. Despite saturating at all densities, ventless …

Genotyping On Custom Arrays Using A Parallel Data Pipeline, Brian Albere

Master's Theses and Capstones

In the past, genotyping (determining a set of alleles in an organism) has been an extremely challenging process. The time, monetary, and technology demands of the task have limited genotype data to a small variety of scientific model organisms with the capacity to conduct genetic crosses. New sequencing technology from companies such as NimbleGen, however, can generate custom organism-specific microarrays at relatively low cost. The combination of these arrays and the knowledge of species' genome-wide SNPs allow genotype experiments, such as generation maps, QTL studies, and natural population variation studies, to be conducted on virtually any organism. Although the NimbleGen …

Valuation Of Ecosystem Services: The Case Of Orseg National Park, Hungary, Ildiko Losonci

Master's Theses and Capstones

A chronic lack of sufficient financial resources has prevented many protected area professionals from achieving adequate ecosystem protection. Using a case study of O&huml;rseg National Park in Hungary and the contingent valuation technique, we examined the relative importance of various ecosystem services to respondents, their WTP for these services, and the oath of honesty's effect on hypothetical bias.

Results from the intercept survey that was administered in the park in the summer of 2011 and filled out by 212 respondents show that visitors prefer the protection of the park's cultural monuments, and ecosystems services like local natural food, climate regulation …

Variations In Carotenoids And Retinol In Milk And Cheese From Jersey Cows At An Organic Dairy Compared To A Conventional Dairy Over A Pasture Season, Amy Rose Beliveau

Master's Theses and Capstones

Carotenoids, widely distributed in nature, are considered to be potentially beneficial in the prevention of a variety of diseases including cardiovascular disease, certain cancers and eye diseases. As humans are unable to synthesize carotenoids, the diet is the only source of these beneficial components. Carotenoid concentration in cow's milk varies greatly as a result of feeding practice and season, but no research thus far has investigated these variations in Jersey cows over an entire pasture season. The objectives of this experiment were to 1) determine the differences in concentrations of carotenoids and retinol in milk from cows consuming different diets, …

Paleobiological And Paleoclimatological Significance Of Stable Isotope Patterns Across Early Eocene Hyracotherium Tooth Rows, Abigail R. D'Ambrosia

Master's Theses and Capstones

The main objective of this study was to determine the most reliable teeth in early Eocene Hyracotherium fossil tooth rows for paleoclimate reconstruction using delta18O values preserved in the tooth enamel. Specimens came from two localities within the Bighorn Basin of Wyoming, D-1204 and D-1583. ANOVA and T-test results generally indicate non-significant differences in mean and variance across tooth rows consisting of m/1, m/2, p/4, and m/3 adult teeth, suggesting any of these teeth may be used for paleoclimate reconstruction purposes as long as sample sizes are large. Additionally, two distinct isotopic patterns were observed across tooth rows, possibly representing …

The Role Of Eelgrass (Zostera Marina L) Source Population Characteristics In Resilience To Stress And Restoration Success, Holly K. Bayley

Master's Theses and Capstones

Eelgrass (Zostera marina L.), an underwater marine flowering plant, has a high degree of morphological plasticity that allows it to survive and grow under a range of conditions and adapt to environmental changes. The degree to which resilience to stress varies among eelgrass populations is important for eelgrass conservation and management. Eelgrass plants from ten genetically differentiated populations were used in a mesocosm experiment where light availability and sediment organic content were manipulated. Productivity and survival were inhibited and morphology was altered by the stress treatments, with these plant responses differing significantly among populations. To further test differences in resilience, …

Adaptation Of A Pseudomonas Aeruginosa Population To A Biofilm Lifestyle: Why Is Polyphosphate Kinase Important?, Keith Ferguson

Master's Theses and Capstones

In the environment, bacterial populations often exist as communities called biofilms. During this sessile state, bacteria excrete exopolysaccharides that form a sticky, protective matrix. This protective matrix also presents a prominent medical challenge since chronic infections of cystic fibrosis (CF) patients are commonly biofilm associated. Pseudomonas aeruginosa is one bacterium that can colonize the CF lung and persist in a biofilm community. During chronic infections, P. aeruginosa adapts to its lung environment and displays genetic and phenotypic diversification. To model evolution during chronic infections, biofilm populations were experimentally evolved for 540 generations and the genetic variation was sampled at 100, …

Multi-Scale Analysis Of Northern Goshawk (Accipiter Gentilis) Breeding Habitat In New Hampshire, Angela Karedes

Master's Theses and Capstones

I compared characteristics of northern goshawk ( Accipiter gentilis) breeding areas (n = 44) to available habitat (n=100 random sites) across New Hampshire at four spatial scales (162, 405, 809 and 1619 ha). Differences in forest composition between breeding areas and available habitat were present (Hotelling-Lawley p = 0.009) with least squares analysis revealing hay/pasture (p < 0.001) and beech/oak (p = 0.004) present less than expected and birch/aspen (p = 0.039) and white pine (p = 0.008) present more than expected, within breeding areas. Analyses also showed that as distance from the core of the breeding area (centered on the nest tree) increased differences between breeding areas and available habitat decreased. Results suggest that, in New Hampshire, goshawks select breeding areas based on nest stand composition and landscape-scale patterns.

Evaluating The Adsorption And Desorption Kinetics Of Suspended Ion Exchangertm (Sixrtm) System, Mark R. Gordon

Master's Theses and Capstones

This research focuses on four primary components of the Suspended Ion eXchangeRTM (SIXRTM) system. The first component was to evaluate the hydraulics of the SIX contactor. It was determined that no matter the flow regime and the paddle speed, the system had the same hydraulic patterns. The second component was to determine the best adsorption kinetics of the system. The best conditions that reached the optimum rate-constant was with a flow rate of 35m3/hr at a paddle speed of 50 Hz (G-value of 482s-1). The third component was to determine the best desorption rate of Dissolved Organic Carbon (DOC) in …

The Distribution Of Direct And Indirect Fitness Effects Of Beneficial Mutations, Rachel Katherine Staples

Master's Theses and Capstones

Rare, beneficial mutations that increase an organism's fitness provide the basis by which adaptation proceeds. Current theory predicts that the individual fitness effects of these beneficial mutations are exponentially distributed, suggesting that mutations conferring a small fitness increase are more numerous than those of large benefit. However, there is little empirical evidence describing measurable fitness effects of individual mutations, nor their availability or effects across a range of environments. We experimentally evolved a single strain of the cystic fibrosis pathogen Burkholderia cenocepacia under both physically structured (biofilm) and unstructured (planktonic) conditions, collected a sample of mutants, and measured the fitness …

Identification Of Factors That Promote The Growth Of Dormant Mycobacterium Avium Subsp. Paratuberculosis, Thu Minh Cao

All Graduate Theses, Dissertations, and Other Capstone Projects

Johne's disease, which is caused by the acid-fast bacterium Mycobacterium avium subspecies paratuberculosis (Mpt), is a chronic, inflammatory intestinal disease that primarily affects ruminants. This disease has a significant effect on the economics of dairy farming. Mpt has a remarkable ability to survive in host tissues for 2-6 years without producing any signs of infection. However, the reliability of diagnostic techniques is limited only to those animals with clinical disease. This may be due to the entry of the organism into a dormant state, which has been reported for other mycobacteria. Reversion to the actively growing state (resuscitation) would improve …

Effect Of Process-Oriented Guided-Inquiry Learning On Non-Majors Biology Students' Understanding Of Biological Classification, Breann Marie Wozniak

All Graduate Theses, Dissertations, and Other Capstone Projects

The purpose of this study was to examine the effect of process-oriented guided-inquiry learning (POGIL) on non-majors college biology students' understanding of biological classification. This study addressed an area of science instruction, POGIL in the non-majors college biology laboratory, which has yet to be qualitatively and quantitatively researched. A concurrent triangulation mixed methods approach was used. Students' understanding of biological classification was measured in two areas: scores on pre and posttests (consisting of 11 multiple choice questions), and conceptions of classification as elicited in pre and post interviews and instructor reflections. Participants were Minnesota State University, Mankato students enrolled in …

Modeling Potential Impacts Of Heavy Metals And Btex Compounds From The Former Year-A-Round Cab Company On Hiniker Pond, Jason Nolan

All Graduate Theses, Dissertations, and Other Capstone Projects

The Year-A-Round Cab Company (an industrial metal preparation, painting, and welding facility) in Mankato, MN has a history of numerous environmental violations. The site is located 300 yards north of Hiniker Pond, a popular swimming spot. The primary purposes of my research were to determine if BTEX (ethyl benzene, toluene, and xylenes) and heavy metals had reached Hiniker Pond, and model estimated contaminate plumes from the Year-A-Round Cab Company. Lead, cadmium, and chromium were found in sediments at levels of up to 30 times higher near the site as compared to the control lake, Hallett's Pond. Although BTEX were not …

Grave Exclamations: An Analysis Of Tombstones And Their Use As Narrative Of Self, Lacey Jae Ritter

All Graduate Theses, Dissertations, and Other Capstone Projects

We establish our selves through narratives--with others and by ourselves--during life. What happens, however, when a person dies? The following paper looks at the way narratives about the deceased's selves are created by the bereaved after their loved ones have died. The paper focuses on the narratives created on the deceased's tombstones, as these are available to the public and last the longest of all final declarations of the person's identity (i.e., obituaries, funeral programs, eulogies). Because I am interested in the way narratives of the self are constructed postmortem, a symbolic interactionist approach was used. The study focuses on …
