A Life History Of The Roundnose Minnow, Dionda Episcopa, In The Middle Pecos River Valley, New Mexico, Michael A. Farrington

Biology ETDs

Life history aspects of Roundnose Minnows, Dionda episcopa, were examined for specimens collected between 2011 and 2013 in El Rito Creek, near Santa Rosa New Mexico. A recent study examining DNA suggested that, instead of supporting a widespread population of the Roundnose Minnow, New Mexico is actually home to two evolutionarily distinct Roundnose Minnow populations. This focus of this study is on the life history attributes of what may become a newly described species of Dionda. Modal class progression analysis (Bhattacharya method) documented four distinct age classes of Roundnose Minnows within El Rito Creek. Sex ratios deviated from the expected …

Gene Duplications During Experimental Evolution Of Caenorhabditis Elegans: Duplication Rates And Evolutionary Responses, James Charles Farslow

Biology ETDs

Copy-number variants (CNVs) are a ubiquitous form of genetic variation. How often this form of variation arises and its adaptive significance are active areas of contemporary research. This work presents evidence regarding both of these subjects. First, it demonstrates that gene duplications occur at a frequency two orders of magnitude greater than point mutations. Specifically, the gene duplication rate is estimated to be 1.2 x 10-7/gene/generation, compared to a point mutation rate on the order of ~10-9/site/ generation. Second, it was found that populations in a low state of fitness due to mutation accumulation could recover some or all of …

Quantifying Temperature Sensitivity Of Soil Respiration Across A Range Of Semi-Arid Biomes, Michelle Nuanez

Biology ETDs

Soils in semi-arid regions store approximately 10% of earths soil organic carbon, the substrate which microbes oxidize, resulting in the largest source of carbon to the atmosphere from terrestrial ecosystems. Semi-arid regions are expected to experience increased temperatures and altered precipitation regimes over the next 100 years, altering soil temperature and water, the two predominant drivers in soil respiration processes. In this study we quantify the temperature sensitivity of soil respiration in five semi-arid biomes ranging from desert grassland to ponderosa pine forest along an elevational/climate gradient in central New Mexico. We measured statistically similar temperature sensitivities in 4 of …

Disturbance Events In Arid Ecosystems: Comparisons Of Enzyme Activity Profiles Across Multiple Soil Microbial Communities, Daniel Douglas Warnock

Biology ETDs

Arid ecosystems are home to approximately 35% of earth's human population, and approximately 40% of earth's terrestrial carbon. These systems are especially prone to releasing the stored carbon when under global climate change (GCC) related pressures. My goal for these studies was to expand on our already growing knowledge base of how the soil microbial communities in disturbed arid ecosystems undergo shifts in functional patterns, as they respond to a rapidly changing environment. In chapter two, I examined the overall functional activity levels and functional behaviors exhibited by both pinon and juniper supported RAM communities in the context of widespread, …

Mens Life History, Testosterone, And Health, Louis Calistro Alvarado

Anthropology ETDs

Testosterone is hypothesized to mediate life history trade-offs between reproduction and survival in men, promoting mating effort over other forms of investment, which entails energetic and mortality costs. Sexually dimorphic musculature represents one form of somatic investment in mating. Favorable energy availability is posited to promote preferential investment in mating effort through upregulated testosterone production and augmented musculature, whereas nutritional constraint is predicted to downregulate testosterone to facilitate a diminished, thriftier phenotype. Furthermore, life history trajectories influencing mens testosterone levels have important health implications for androgen-sensitive disease. Here, I examine broad features of men's life history and health, and their …

Lossy Projective Hashing And Its Applications, Haiyang Xue, Yamin Liu, Xianhui Lu, Bao Li

Research Collection School Of Computing and Information Systems

In this paper, we introduce a primitive called lossy projective hashing. It is unknown before whether smooth projective hashing (Cramer-Shoup, Eurocrypt’02) can be constructed from dual projective hashing (Wee, Eurocrypt’12). The lossy projective hashing builds a bridge between dual projective hashing and smooth projective hashing. We give instantiations of lossy projective hashing from DDH, DCR, QR and general subgroup membership assumptions (including 2k-th residue, p-subgroup and higher residue assumptions). We also show how to construct lossy encryption and fully IND secure deterministic public key encryption from lossy projective hashing. – We give a construction of lossy projective hashing via dual …

Problem Solving And Tool Use In Three Species Of Otter, Robert F. Gormley

Masters Theses and Doctoral Dissertations

Sea otters are well known tool users, yet the cognitive capacities of other otter species have been sparsely studied. Precedent exists for non-tool using species closely related to native tool users to display comparable abilities under experimental conditions. The social intelligence hypothesis predicts complex cognitive capacities in socially complex species. Using the Aesop’s Fable paradigm – wherein subjects drop stones into a cylinder half-filled with water to acquire floating out-of-reach food items – I assessed North American river otters’, Asian small-clawed otters, and giant river otters abilities to solve a novel tool-mediated problem. Sticks and water were presented with the …

Becoming American: Constructing Mexican Immigrants In Local Newspapers, Zheng Zhu

Publications and Research

Media representation of Latino immigrants has been extensively studied by scholars across diverse academic disciplines. Particular to the U.S. context, preceding scholarships pertaining to the ways in which Latinos were represented centered on the media representation of Latino immigrants either as the exotic racial other or undesirable foreigners. In light of the important role that the Mexican immigrants played in understanding the current national debate on illegal immigration and the overall historical experiences of immigrants in Washington State (WA), this study critically investigated how news articles published in WA represented Mexican immigrants. As a crucial point of departure from prior …

The Texas Heart Institute Journal

Evolving technology and improvements in the design of modern, continuous-flow left ventricular assist devices have substantially reduced the rate of device malfunction. As the number of implanted devices increases and as survival prospects for patients with a device continue to improve, device malfunction is an increasingly common clinical challenge. Here, we present our initial experience with an endovascular microaxial flow left ventricular assist device as a successful bridge to transplantation in a 54-year-old man who experienced left ventricular assist device malfunction.

Spectrums, Subgroups And School-Lunch: The Linguistic Capital Of Students With Autism, Scott Belden

Theses and Dissertations

Individuals with autism spectrum disorders (ASD) are known to have difficulties with pragmatic language. There is, however, a subpopulation of those with ASD that exhibits a high competency with pragmatic language. It can be difficult for researchers to find natural contexts to record these high-functioning individuals and examine their spontaneous use of pragmatic language. Additionally, there is a need to move beyond analyzing the cognitive abilities of these individuals to a sociolinguistic exploration of how they use pragmatic abilities to form and navigate social groups.

The research involved in this thesis included audio-visual recordings of 14 high school students with …

Instrumental Music Participation And The Differences In Academic Performances For Students In Poverty, Shawn A. Oban

Theses and Dissertations

Because of the emphasis on No Child Left Behind and high stakes testing, school districts and administrators have been limiting or eliminating fine arts courses from an already shrinking curriculum, focusing on the subjects being tested. Students living in poverty are often entering formal schooling behind academically.

The researcher examined longitudinal test data from 2010-2015 from middle school aged students in a large Midwest school district. The researcher focused on test scores from the sixth grade when instrumental music was offered, examined test data from tenth grade, and studied academic growth. All student scores were included, but the independent variables …

Any Versus Long-Term Prescribing Of High Risk Medications In Older People Using 2012 Beers Criteria: Results From Three Cross-Sectional Samples Of Primary Care Records For 2003/4, 2007/8 And 2011/12, A Ble, Jah Masoli, He Barry, Re Winder, Et Al

School of Health Professions

BACKGROUND: High risk medications are commonly prescribed to older US patients. Currently, less is known about high risk medication prescribing in other Western Countries, including the UK. We measured trends and correlates of high risk medication prescribing in a subset of the older UK population (community/institutionalized) to inform harm minimization efforts. METHODS: Three cross-sectional samples from primary care electronic clinical records (UK Clinical Practice Research Datalink, CPRD) in fiscal years 2003/04, 2007/08 and 2011/12 were taken. This yielded a sample of 13,900 people aged 65 years or over from 504 UK general practices. High risk medications were defined by 2012 …

Naquin V. Elevating Boats, Llc: The Fifth Circuit’S Improper Expansion Of Jones Act “Seaman Status” Qualification, Timothy M. O'Hara

Pace Law Review

The story began nearly a century ago, when Congress enacted the Jones Act and effectively made “seamen the most generously treated personal injury victims in American law.” But defining a Jones Act seaman has not come easy, as it took the United States Supreme Court seventy five years to arrive at the modern seaman status test. This commentary examines the “tortured history” of the Jones Act, how qualification for the statute’s protections has evolved, the modern seaman status test, and the implications of the Fifth Circuit’s recent application thereof. Section II gives a brief history and explanation of maritime law …

Fundamental Unenumerated Rights Under The Ninth Amendment And The Privileges Or Immunities Clause, Adam Lamparello

Akron Law Review

The failure to link the Ninth Amendment and Privileges or Immunities Clause for the purpose of creating unenumerated fundamental rights has been a persistent but rarely discussed aspect of the Court’s jurisprudence. That should change. There need not be an ongoing tension between the Court’s counter-majoritarian role and the authority of states to govern through the democratic process. If the Constitution’s text gives the Court a solid foundation upon which to recognize new rights and thereby create a more just society, then the exercise of that power is fundamentally democratic. The Ninth Amendment and Privileges or Immunities Clause provides that …

The Five Days In June When Values Died In American Law, Bruce Ledewitz

Akron Law Review

During a five day period in June, 1992, every Justice on the United States Supreme Court joined one or the other of two opinions that denied the objectivity of values—either Justice Kennedy’s majority opinion in Lee v. Weisman or Justice Scalia’s dissent in Planned Parenthood v. Casey. Both of these opinions expressed the view that normative judgments are merely human constructions. This moment represents symbolically the death of values in American law. The arrival of nihilism at the heart of American law is a world-changing event for law that must be acknowledged.

The death of values was announced by …

Genetic Analyses Determine Connectivity Among Cave And Surface Populations Of The Jamaican Endemic Freshwater Crab Sesarma Fossarum In The Cockpit Country, Manuel Stemmer, Christoph D. Schubart

International Journal of Speleology

The Jamaican freshwater crab Sesarma fossarum (Decapoda: Brachyura: Sesarmidae) is endemic to western central Jamaica where it occurs in cave and surface streams of karst regions. In the present study, we examine the population genetic structure of the species, providing evidence for intraspecific differentiation and genetic substructure among twelve sampled populations. Interestingly, crabs from caves appear genetically undistinguishable from representatives of nearby surface waters, despite previously observed and described morphometric differentiation. In contrast, genetic isolation takes place among populations from rivers and caves belonging to different watersheds. In one case, even populations from different tributaries of the same river were …

Multi­Language Machine Translation Speech Corrector, Polar Bear Ratinov, Dimitri Kanevsky

Defensive Publications Series

A system and method are proposed that will leverage language models from multiple language machine translations (MT) for better speech recognition. Wherever ambiguity exists in interpreting speech, the system identifies each transcribed option of homophones for interpretation through translation. The system then translates each sentence corresponding to the options of homophones into multiple languages. The method comprises a scoring system that is used by the machine translation system for assessing translations whereby the translation which makes less sense is given a lower score. The system combines the scores assigned to each translated homophone in the various languages and selects the …
