How Do Shellfisheries Influence Genetic Connectivity In Metapopulations? A Modeling Study Examining The Role Of Lower Size Limits In Oyster Fisheries, Daphne M. Munroe, Eileen E. Hofmann, Eric N. Powell, John M. Klinck

CCPO Publications

Fisheries can potentially alter evolutionary processes such as genetic connectivity and lead to genotypic changes in stocks. Using an individual-based metapopulation genetics model, we examined the possible influence of oyster (Crassostrea virginica) fisheries on genetic connectivity. We simulated a range of realistic fishing pressures, with and without a minimum size limit (limit = 63.5 mm), over a range of fishing scenarios including single-area and stock-wide fisheries. Movement of a neutral marker gene provided an indicator of gene transfer between populations. Simulations showed that fishing may alter genetic connectivity. Increasing fishing pressure tended to decrease potential for fished populations …

On The Role Of Coastal Troughs In The Circulation Of Warm Circumpolar Deep Water On Antarctic Shelves, Pierre St-Laurent, John M. Klinck, Michael S. Dinniman

CCPO Publications

Oceanic exchanges across the continental shelves of Antarctica play an important role in biological systems and the mass balance of ice sheets. The focus of this study is on the mechanisms responsible for the circulation of warm Circumpolar Deep Water (CDW) within troughs running perpendicular to the continental shelf. This is examined using process-oriented numerical experiments with an eddy-resolving (1 km) 3D ocean model that includes a static and thermodynamically active ice shelf. Three mechanisms that create a significant onshore flow within the trough are identified: 1) a deep onshore flow driven by the melt of the ice shelf, 2) …

Advances In Marine Ecosystem Dynamics From Us Globec: The Horizontal-Advection Bottom-Up Forcing Paradigm, Emanuele Di Lorenzo, David Mountain, Harold Batchelder, Nicholas Bond, Eileen E. Hofmann

CCPO Publications

A primary focus of the US Global Ocean Ecosystem Dynamics (GLOBEC) program was to identify the mechanisms of ecosystem response to large- scale climate forcing under the assumption that bottom-up forcing controls a large fraction of marine ecosystem variability. At the beginning of GLOBEC, the prevailing bottom-up forcing hypothesis was that climate-induced changes in vertical transport modulated nutrient supply and surface primary productivity, which in turn affected the lower trophic levels (e.g., zooplankton) and higher trophic levels (e.g., fish) through the trophic cascade. Although upwelling dynamics were confirmed to be an important driver of ecosystem variability in GLOBEC studies, the …

Primary Antiretroviral Drug Resistance Profiles Among Hiv-1 Therapy Naïve Patients In Two Referral Hospitals In Kenya, Simon Onsongo Nyangena

Master of Medicine in Clinical Pathology

Objective: To characterize antiretroviral drug resistance mutations among drug naïve patients in two referral hospitals in Kenya Background: Acquired immunodeficiency syndrome (AIDS) caused by Human immunodeficiency virus (HIV) was first described in 1982. Since then the virus has spread globally to infect millions of people. HIV was first described in Kenya in the period between 1984/1985. Currently, Kenya has an estimated HIV-1 prevalence of 6.2% with a country population of about 40 million people. With the introduction of antiretroviral drugs, the survival of most HIV patients has been prolonged markedly. However this is greatly threatened by increasing rates of antiretroviral …

Role Of 18F-Fdg Pet Scan In Rheumatoid Lung Nodule: Case Report And Review Of The Literature, Christine L. Chhakchhuak, Mehdi Khosravi, Kristine M. Lohr

Internal Medicine Faculty Publications

Flourine-18 fluoro-2-deoxy-glucose (¹⁸F-FDG) positron emission tomography combined with computed tomography (PET/CT) is a useful test for the management of malignant conditions. Inflammatory and infectious processes, however, can cause increased uptake on PET scanning, often causing diagnostic dilemmas. This knowledge is important to the rheumatologist not only because of the inflammatory conditions we treat but also because certain rheumatic diseases impose an increased risk of malignancy either due to the disease itself or as a consequence of medications used to treat the rheumatic diseases. There is an increasing body of evidence investigating the role of PET scans in inflammatory …

Effects Of Emotion Regulation Strategies On Sexual Risk-Taking, Monica Lackups

Master's Theses and Doctoral Dissertations

Sexual risk-taking is a growing problem and an area where there are significant individual differences in behavior. One contributing factor to risky sexual behavior may be emotion regulation difficulties. For example, suppression has negative effects on emotion experience, while reappraisal leads to increased well-being. Previous research has demonstrated the use of sexual behavior as an emotion regulation strategy in victimized populations. This study investigated whether emotion regulation strategies influence sexual risk-taking in a non-clinical college population. Individuals with higher levels of emotion regulation difficulties and higher suppression use engaged in more frequent sexual risk-taking behavior, whereas individuals who used reappraisal …

Legislation To Protect The Welfare Of Fish, Kelly Levenda

Animal Law Review

This Article examines the marginalization of fish under current animal welfare laws and regulations, explores the treatment of farm-raised fish during transport and slaughter, and proposes legislation and regulations in these two areas. While evidence indicates that fish are capable of experiencing pain, fear, and suffering—the traditional considerations informing concepts of animal welfare—current pre-slaughter transport and slaughter practices are completely uninformed by notions of fish welfare. Comparing the cognitive and sensory capacities of fish to other animals currently receiving animal welfare recognition through official regulation, this Article argues that protections afforded to animals during transport and slaughter should similarly apply …

Not Alll Dogs Go To Heaven: Judaism's Lessons In Beastly Morality, Mark Goldfeder

Animal Law Review

This Essay examines the moral status of animals and the definition of humanity under traditional Jewish law, as contained in Biblical texts and commentaries by ancient and historical Jewish scholars. Examining whether animals are capable of moral behavior, it provides examples from various Judaic sources to support the idea that animals are capable of making conscious, moral choices. This Essay goes on to investigate the effect that morality has on the rights and rewards given to animals under Jewish law, and whether, as conscious moral actors, animals have souls. Turning more broadly to the definition of humanity, this Essay discusses …

Shocked, Horrified, Sickened: How Cigarettes (And The Lessons From The Tobacco Litigation) Can Take Years Off Animal-Based Food Industries, Amanda Winalski

Animal Law Review

Animal-based food industries—meat, egg, and dairy—have a history of opposing even relatively minor attempts to reduce human consumption of animal-based foods. In the face of growing evidence that eating meat, eggs, and dairy is detrimental to human health, these industries and their supporters maintain the opposite: that these foods are essential for a healthy diet and have no negative impact as normally consumed. Recognizing parallels between animal-based food industries and another industry heavily invested in maintaining the notion that its product was benign as normally consumed, this Article argues the tobacco litigation saga holds instructive lessons for combatting the current …

Sustainable Slope Stabilization Using Recycled Plastic Pin In Texas, Mohammad Sadik Khan

Civil Engineering Dissertations - Archive

Shallow slope failures are predominant in the North Texas area and pose significant maintenance problems for the Texas Department of Transportation (TxDOT). As a cost effective alternative, the Recycled Plastic Pin (RPP) can be utilized to stabilize the shallow slope failure. RPP are fabricated from recycled plastics and waste materials (i.e. polymers, sawdust, and fly ash). It is a lightweight material and less susceptible to chemical and biological degradation than alternative reinforcing element. RPPs are driven into the slope face, which provide additional resistance along the slip surface and increase the factor of safety. The current study summarized the remediation …

Antifragility Analysis And Measurement Framework For Systems Of Systems, John Johnson, Adrian V. Gheorghe

Engineering Management & Systems Engineering Faculty Publications

The twenty-first century is defined by the social and technical hazards we face. A hazardous situation is a condition, or event, that threatens the well-being of people, organizations, societies, environments, and property. The most extreme of the hazards are considered X-Events and are an exogenous source of extreme stress to a system. X-Events can also be the unintended outputs of a system with both positive (serendipitous) and negative (catastrophic) consequences. Systems can vary in their ability to withstand these stress events. This ability exists on a continuum of fragility that ranges from fragile (degrading with stress), to robust (unchanged by …

Air-Sea Dimethylsulfide (Dms) Gas Transfer In The North Atlantic: Evidence For Limited Interfacial Gas Exchange At High Wind Speed, T. G. Bell, Warren J. De Bruyn, S. D. Miller, B. Ward, K. Christensen, E. S. Saltzman

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Shipboard measurements of eddy covariance dimethylsulfide (DMS) air-sea fluxes and seawater concentration were carried out in the North Atlantic bloom region in June/July 2011. Gas transfer coefficients (k(660)) show a linear dependence on mean horizontal wind speed at wind speeds up to 11 m s(-1). At higher wind speeds the relationship between k(660) and wind speed weakens. At high winds, measured DMS fluxes were lower than predicted based on the linear relationship between wind speed and interfacial stress extrapolated from low to intermediate wind speeds. In contrast, the transfer coefficient for sensible heat did not exhibit this effect. The apparent …

Daily Temperature Fluctuations Unpredictably Influence Developmental Rate And Morphology At A Critical Early Larval Stage In A Frog, Juliana M. Arrighi, Ezra S. Lencer, Advait Jukar, Daesik Park, Patrick C. Phillips, Robert H. Kaplan

Complex Systems Faculty Publications and Presentations

Background: Environmental temperature has profound consequences for early amphibian development and many field and laboratory studies have examined this. Most laboratory studies that have characterized the influence of temperature on development in amphibians have failed to incorporate the realities of diel temperature fluctuations (DTF), which can be considerable for pond-breeding amphibians.

Results: We evaluated the effects of different ecologically relevant ranges of DTF compared with effects of constant temperatures on development of embryos and larvae of the Korean fire-bellied toad (Bombina orientalis). We constructed thermal reaction norms for developmental stage, snout- vent length, and tail length by fitting …

Evaluation Of Handling Equipment Sound Pressure Levels As Stressors In Beef Cattle, Christina M. Lyvers

Theses and Dissertations--Biosystems and Agricultural Engineering

Sound pressure level (SPL) is known to cause stress in cattle but is often overlooked as a potential source of fear for cattle when designing handling equipment. Current literature does not offer guidelines for the design of equipment with regard to SPL. It is, however, recommended that handling equipment should be designed to minimize the SPL during handling. The purpose of this experiment was to measure stress levels in a group of cattle which were subjected to a series of varying sounds in order to determine a design threshold limit for handling equipment. Treatments included two frequencies, 1 kHz and …

Using Gis To Delineate Headwater Stream Origins In The Appalachian Coal-Belt Region Of Kentucky, Jonathan A. Villines

Theses and Dissertations--Biosystems and Agricultural Engineering

Human activity such as surface mining can have substantial impacts on the natural environment. Performing a Cumulative Hydrologic Impact Assessment (CHIA) of such impacts on surface water systems requires knowing the location and extent of these impacted streams. The Jurisdictional Determination (JD) of a stream’s protected status under the Clean Water Act (CWA) involves locating and classifying streams according to their flow regime: ephemeral, intermittent, or perennial. Due to their often remote locations and small size, taking a field inventory of headwater streams for surface mining permit applications or permit reviews is challenging. A means of estimating headwater stream location …

Genetic Diversity Of North American Captive-Born Gorillas (Gorilla Gorilla Gorilla), Noah D. Simmons, Ronald S. Wagner, Joseph G. Lorenz

All Faculty Scholarship for the College of the Sciences

Western lowland gorillas (Gorilla gorilla gorilla) are designated as critically endangered and wild populations are dramatically declining as a result of habitat destruction, fragmentation, diseases (e.g., Ebola) and the illegal bushmeat trade. As wild populations continue to decline, the genetic management of the North American captive western lowland gorilla population will be an important component of the long‐term conservation of the species. We genotyped 26 individuals from the North American captive gorilla collection at 11 autosomal microsatellite loci in order to compare levels of genetic diversity to wild populations, investigate genetic signatures of a population bottleneck and identify …

Mothers' Reponses To Infant Gesture At 17 Months, Carly Seibel

Honors Capstones

Mothers' responses to infants' gestures are proposed as a mechanism for vocabulary acquisition. It is known that at 13 months mothers give more object labels to pointing than object extensions at a time when infants are learning object labels. However, it is not known how mothers respond to infants' gestures at 17 months when their vocabularies are expanding to include a greater variety of word types. Therefore, the current study examined mothers' responses to three types of infant gestures: points, open-hand reaches, and object extensions at 17 months to describe maternal provision of object labels, action labels, internal state labels …

Screening Of Chemical Libraries In Search Of Inhibitors Of Aflatoxin Biosynthesis, Justin Durancik

Honors Capstones

Aspergillus nidulans is a filamentous fungus and model organism for other Aspergillus species, such as A. flavus. A. flavus and some other Aspergillus species produce a toxin known as aflatoxin. This compound is a carcinogenic secondary metabolite produced by these organisms. A. nidulans is often used to study this pathway because it presents a conserved biosyntheticpathway that leads to the production of the related mycotoxin sterigmatocystin (ST). For my project, I have searched for chemicals that disrupt the activation of the biosynthetic pathway responsible for producing aflatoxin. Specifically, I screened for chemicals that inhibit the nuclear VeA-LaeA protein-protein interaction. This …

Comparative Analysis Of English Language Learners' Experiences In Public School At The Third And Eighth Grade Levels, Amanda Lenox, Kristin Liewald

Honors Capstones

The field of education is one that endeavors constant change of fluctuating degrees. Most recently and drastically, the educational field has experienced and responded to changes in the cultural and linguistic diversity that is rapidly increasing in classrooms across the United States. Congruently, current legislation holds both educators and students accountable for their standardized performance and accomplishments, although teachers of ethnically diverse students are not required to be certified in the teaching of these learners. As a result, it was the purpose of this study to identify and analyze the themes evident from a series of observations and interviews conducted …

Prevalence Of Vitamin D Deficiency In An Ethnic African Urban Obstetric Population In An Equatorial City Hospital, Raj Hasmukh Dodia

Master of Medicine in Obstetrics and Gynecology

Introduction: Low Vitamin D levels in pregnancy have been associated with an increased risk of gestational diabetes, pre-eclampsia, bacterial vaginosis, preterm birth, disordered fetal skeletal homeostasis, and impaired offspring lung health. As a result, current public health advice in several countries is to universally supplement Vitamin D during pregnancy. Data regarding the Vitamin D levels of the ethnic obstetric population in Kenya are not available; hence recommendations for Vitamin D supplementation have no scientific basis. Objectives of study: This research was carried out to determine the prevalence of deficiency of Vitamin D in ethnic African obstetric patients who had delivered …
