Smooth Positive Solutions To An Elliptic Model With C2 Functions, Joon Hyuk Kang

Faculty Publications

Two species of animals are competing or cooperating in the same environment. Under what conditions do they coexist peacefully? Or under what conditions does either one of the two species become extinct, that is, is either one of the two species excluded by the other? We investigate this phenomena in mathematical point of view.

In this paper we concentrate on coexistence solutions of the competition or cooperation model

This system is the general model for the steady state of a competitive or cooperative interacting system depending on growth conditions for and . The techniques used in this paper are elliptic …

Does Pornography Consumption Increase Participation In Friends With Benefits Relationships?, Scott R. Braithwaite, Sean C. Aaron, Krista Joy Dowdle, Kersti A. Spjut, Frank D. Fincham

Faculty Publications

Friends with benefits (FWB) relationships integrate two types of relationships—friendship and a relationship that includes sexual intimacy but without an expectation of commitment. These relationships are often seen as less risky than other casual sexual behaviors, but they still pose a high risk of contracting an STI. Pornography consumption has been connected to increases in risky sexual behavior in other types of casual sex. In two studies (Study 1 N = 850; Study 2 N = 992), we examined the hypothesis that pornography use influences FWB behaviors, specifically through the mechanism of sexual scripts. Our results demonstrate that more frequent …

Socioeconomic Status And Health: Education And Income Are Independent And Joint Predictors Of Ambulatory Blood Pressure, Wendy C. Birmingham, Jenny M. Cundiff, Bert N. Uchino, Timothy W. Smith

Faculty Publications

Epidemiological research suggests that different indicators of socioeconomic status (SES) such as income and education may have independent and/or interactive effects on health outcomes. In this study, we examined both simple and more complex associations (i.e., interactions) between different indicators of SES and ambulatory blood pressure (ABP) during daily life. Our sample consisted of 94 married couples who completed a one-day ABP protocol. Both income and education were independently related to systolic blood pressure and only income was significantly related to diastolic blood pressure. There were also statistical interactions such that individuals with high levels of both income and education …

The Dependability Of Electrophysiological Measurements Ofperformance Monitoring In A Clinical Sample: A Generalizability Anddecision Analysis Of The Ern And Pe, Scott A. Baldwin, Michael J. Larson, Peter E. Clayson

Faculty Publications

Psychometric studies of the ERN, CRN, Pe, and Pc ERPs are increasing. Coherent integration of these results is difficultwith classical test theory because the definition of error depends on the measure of reliability. This study usedgeneralizability theory, which extends the ideas of classical test theory, as a framework for evaluating the influence ofpsychopathology and number of trials on dependability of measurement. Participants included 34 people meeting criteriafor major depression, 29 meeting criteria for an anxiety disorder, and 319 controls. For all ERPs, within-person variancewas larger than between-person variance across groups, indicating many trials are needed for adequate dependability (atleast 13). …

Beyond The Expansion Framework: How Same-Sex Marriage Changes The Institutional Meaning Of Marriage And Heterosexual Men's Conception Of Marriage, Alan J. Hawkins, Jason S. Carroll

Faculty Publications

Social institutions profoundly affect human behavior. They provide human relationships with meaning, norms, and patterns, and in doing so encourage and guide conduct; they are the "humanly devised constraints that shape human interaction." That is their function. And when the definitions and norms that constitute a social institution change, the behaviors and interactions that the institution shapes also change.

Metazoan Parasites Of Antarctic Fishes, Mehmet Cemal Oğuz, Yahya Tepe, Mark C. Belk, Richard A. Heckmann, Burçak Aslan, Meryem Gürgen, Rodney A. Bray, Ülker Akgül

Faculty Publications

To date, there have been nearly 100 papers published on metazoan parasites of Antarctic fishes, but there has not yet been any compilation of a species list of fish parasites for this large geographic area. Herein, we provide a list of all documented occurrences of monogenean, cestode, digenean, acanthocephalan, nematode, and hirudinean parasites of Antarctic fishes. The list includes nearly 250 parasite species found in 142 species of host fishes. It is likely that there are more species of fish parasites, which are yet to be documented from Antarctic waters.

Faculty Publications

© 2015 The Obesity Society. Objective Chronic, low-grade adipose tissue inflammation associated with adipocyte hypertrophy is an important link in the relationship between obesity and insulin resistance. Although ubiquitin ligases regulate inflammatory processes, the role of these enzymes in metabolically driven adipose tissue inflammation is relatively unexplored. Herein, the effect of the ubiquitin ligase Siah2 on obesity-related adipose tissue inflammation was examined. Methods Wild-type and Siah2KO mice were fed a low- or high-fat diet for 16 weeks. Indirect calorimetry, body composition, and glucose and insulin tolerance were assayed along with glucose and insulin levels. Gene and protein expression, immunohistochemistry, adipocyte …

Reciprocal Osmotic Challenges Reveal Mechanisms Of Divergence In Phenotypic Plasticity In The Killifish Fundulus Heteroclitus, Reid S. Brennan, Fernando Galvez, Andrew Whitehead

Faculty Publications

© 2015. Published by The Company of Biologists Ltd. The killifish Fundulus heteroclitus is an estuarine species with broad physiological plasticity, enabling acclimation to diverse stressors. Previous work suggests that freshwater populations expanded their physiology to accommodate low salinity environments; however, it is unknown whether this compromises their tolerance to high salinity.We used a comparative approach to investigate the mechanisms of a derived freshwater phenotype and the fate of an ancestral euryhaline phenotype after invasion of a freshwater environment. We compared physiological and transcriptomic responses to high-and low-salinity stress in fresh and brackish water populations and found an enhanced plasticity …

Preserved Filamentous Microbial Biosignatures In The Brick Flat Gossan, Iron Mountain, California, Amy J. Williams, Dawn Y. Sumner, Charles N. Alpers, Suniti Karunatillake, Beda A. Hofmann

Faculty Publications

© Copyright 2015, Mary Ann Liebert, Inc. 2015. A variety of actively precipitating mineral environments preserve morphological evidence of microbial biosignatures. One such environment with preserved microbial biosignatures is the oxidized portion of a massive sulfide deposit, or gossan, such as that at Iron Mountain, California. This gossan may serve as a mineralogical analogue to some ancient martian environments due to the presence of oxidized iron and sulfate species, and minerals that only form in acidic aqueous conditions, in both environments. Evaluating the potential biogenicity of cryptic textures in such martian gossans requires an understanding of how microbial textures form …

Bioturbating Animals Control The Mobility Of Redox-Sensitive Trace Elements In Organic-Rich Mudstone, Dario Harazim, Duncan Mcilroy, Nicholas P. Edwards, Roy A. Wogelius, Phillip L. Manning, Kristin M. Poduska, Graham D. Layne, Dimosthenis Sokaras, Roberto Alonso-Mori, Uwe Bergmann

Faculty Publications

© 2015 Geological Society of America. Bioturbating animals modify the original mineralogy, porosity, organic content, and fabric of mud, thus affecting the burial diagenetic pathways of potential hydrocarbon source, seal, and reservoir rocks. High-sensitivity, synchrotron rapid scanning X-ray fluorescence elemental mapping reveals that producers of phycosiphoniform burrows systematically partition redox-sensitive trace elements (i.e., Fe, V, Cr, Mn, Co, Ni, Cu, and As) in fine-grained siliciclastic rocks. Systematic differences in organic carbon content (total organic carbon >1.5 wt%) and quality (Δ13Corg~0.6%) are measured between the burrow core and host sediment. The relative enrichment of redox-sensitive elements in the burrow core does …

The Use Of Shear Rate-Diameter Dose-Response Curves As An Alternative To The Flow-Mediated Dilation Test, Brian Wu, Daniel Credeur, Simon Fryer, Lee Stoner

Faculty Publications

The brachial artery flow-mediated dilation test (FMD) is the non-invasive gold-standard used to test endothelial function. Reduced FMD precedes the development of atherosclerosis and provides an early marker for predicting future cardiovascular disease events. Although, this test is of high potential, it is somewhat limited by poor reproducibility. By utilizing hand warming and grip exercise combined with hierarchical linear modeling, shear rate-diameter dose-response curves may provide a novel and more accurate way to assess endothelial function in humans. Shear rate-diameter dose-response curves could potentially improve upon the traditional FMD measurement and serve as a superior clinical and research tool for …

Estimating The Sex Composition Of The Summer Flounder Catch Using Fishery-Independent Data, Jason M. Morson, Eleanor A. Bochenek, Eric N. Powell, Emerson C. Hasbrouck, Jennifer E. Gius, Charles F. Cotton, Kristin Gerbino, Tara Froehlich

Faculty Publications

Models that account for sex-specific behavior and population dynamics are becoming more common in the stock assessment of sexually dimorphic fishes. However, such models can be data intensive and require some knowledge or assumptions about the sex ratio of fishery landings. A recent stock assessment review of Summer Flounder Paralichthys dentatus identified the need to account for sex-specific fishing mortality in the assessment model; however, no data on the sex composition of the catch were available. Fishery-independent, sex-specific information for this species is collected annually by the National Marine Fisheries Service's Northeast Fisheries Science Center during their bottom trawl survey. …

Learning Love From A Tiger: Approaches To Nature In An American Buddhist Monastery, Daniel S. Capper

Faculty Publications

In current debates about Buddhist approaches to the non-human natural world, studies describe Buddhism variously as anthropocentric, biocentric or ecocentric. These perspectives derive for the most part from examinations of philosophical and normative aspects of the tradition without much attention to moments when embodied practice diverges from religious ideals. Responding to the need for narrative thick descriptions of lived Buddhist attitudes toward nature, I ethnographically explore a Vietnamese monastery in the United States. There I find multifaceted Buddhist approaches to nature which sometimes disclose disunity between theory and practice. Philosophically and normatively, this monastery embraces ecocentrism through notions of interconnectedness, …

An Autonomic Performance Environment For Exascale, Kevin A. Huck, Allan Porterfield, Nick Chaimov, Hartmut Kaiser, Allen D. Malony, Thomas Sterling, Rob Fowler

Faculty Publications

Exascale systems will require new approaches to performance observation, analysis, and runtime decision-making to optimize for performance and efficiency. The standard "first-person" model, in which multiple operating system processes and threads observe themselves and record first-person performance profiles or traces for offline analysis, is not adequate to observe and capture interactions at shared resources in highly concurrent, dynamic systems. Further, it does not support mechanisms for runtime adaptation. Our approach, called APEX (Autonomic Performance Environment for eXascale), provides mechanisms for sharing information among the layers of the software stack, including hardware, operating and runtime systems, and application code, both new …

PLGA scaffolds have been used to regenerate damaged tissues together with stem cell-based therapy. There is solid evidence that the development of PLGA microparticles and nanoparticles may be beneficial to a wide range of dental fields such as endodontic therapy, dental caries, dental surgery, dental …

Monolithic Optofluidic Ring Resonator Lasers Created By Femtosecond Laser Nanofabrication, Hengky Chandrahalim, Qiushu Chen, Ali A. Said, Mark Dugan, Xudong Fan

Faculty Publications

We designed, fabricated, and characterized a monolithically integrated optofluidic ring resonator laser that is mechanically, thermally, and chemically robust. The entire device, including the ring resonator channel and sample delivery microfluidics, was created in a block of fused-silica glass using a 3-dimensional femtosecond laser writing process. The gain medium, composed of Rhodamine 6G (R6G) dissolved in quinoline, was flowed through the ring resonator. Lasing was achieved at a pump threshold of approximately 15 μJ/mm². Detailed analysis shows that the Q-factor of the optofluidic ring resonator is 3.3 × 10⁴, which is limited by both solvent …

An Investigation Of Tree Biomass In The Great Smoky Mountains National Park, Curt Skipper, Patrick Stokley, Sherry S. Herron

Faculty Publications

We determined the biomass (carbon storage) of four forest types in the Great Smokey Mountains National Park; pine/oak, cove hardwood, northern hardwood, and spruce/fir. Based on the GLOBE Programs land cover protocols (www.globe.gov), and the University of New Hampshire's GLOBE Carbon Cycle Program (http;//globecarboncycle.unh.edu/), we knew that species and tree circumference would be the two most critical factors in determining biomass, but we also hypothesized that number of trees in a study site and the elevation of the site would impact biomass. We hypothesized that old growth forest would contain greater biomass than a young forest. …

Exploring Intensive Longitudinal Measures Of Student Engagement In Blended Learning, Curtis R. Henrie, Robert Bodily, Kristine C. Manwaring, Charles R. Graham

Faculty Publications

In this exploratory study we used an intensive longitudinal approach to measure student engagement in a blended educational technology course, collecting both self-report and observational data. The self-report measure included a simple survey of Likert-scale and open-ended questions given repeatedly during the semester. Observational data were student activity data extracted from the learning management system. We explored how engagement varied over time, both at the course level and between students, to identify patterns and influences of student engagement in a blended course. We found that clarity of instruction and relevance of activities influenced student satisfaction more than the medium of …

Modeling Light Gas And Tar Yields From Pyrolysis Of Green River Oil Shale Demineralized Kerogen Using The Chemical Percolation Devolatilization Model, Daniel Barfuss, Ronald J. Pugmire, Thomas H. Fletcher

Faculty Publications

Recent detailed chemical structure analyses of three demineralized kerogens from Green River oil shale samples were used to generate input parameters for the chemical percolation devolatilization (CPD) model. This model uses a lattice network to describe pyrolysis of solid hydrocarbons, such as coal and biomass. It was necessary to modify the formulation of the CPD model to account for the long aliphatic carbon chains found in oil shale, because gases formed from these long chains condense at room temperature and are counted as tar. It was initially assumed that 20% of the aliphatic material was released as light gas during …

Ontology-Based Information Extraction With A Cognitive Agent, Deryle W. Lonsdale, David W. Embley, Peter Lindes

Faculty Publications

Machine reading is a relatively new field that features computer programs designed to read flowing text and extract fact assertions expressed by the narrative content. This task involves two core technologies: natural language processing (NLP) and information extraction (IE). In this paper we describe a machine reading system that we have developed within a cognitive architecture. We show how we have integrated into the framework several levels of knowledge for a particular domain, ideas from cognitive semantics and construction grammar, plus tools from prior NLP and IE research. The result is a system that is capable of reading and interpreting …

Copyright And The Living Dead?: Succession Law And The Postmortem Term, Eva E. Subotnik

Faculty Publications

(Excerpt)

Intellectual property (“IP”) policy in the United States is primarily aimed at stimulating the creative, inventive, and socially enriching behavior of the living. Yet one key aspect of our incentive-based regime is intimately linked to the death of the creative contributor. Specifically, the term of copyright generally lasts for seventy years following the death of the author. Such a feature is not the product of policy choices in place from time immemorial but rather reflects a contemporary decision to link the duration of exclusive rights to some fixed point in time beyond the author’s death. In particular, until the …

Fitting The Forum To The Pernicious Fuss: A Dispute System Design To Address Implicit Bias And 'Isms In The Workplace, Elayne E. Greenberg

Faculty Publications

(Excerpt)

This paper proposes a dispute system design to address workplace discrimination caused by implicit biases so that employees and employers involved in such disputes can secure a more responsive justice than existing legal processes are able to provide. Workplace discrimination caused by implicit bias continues to contaminate our work environment despite our focused legal efforts to combat such overt "isms" as sexism, racism, ageism, and ableism. Although overt expressions of bias have significantly decreased in recent years, expressions of implicit bias, the primary cause of workplace discrimination, persists.

This paper extends the research on implicit bias to dispute system …

First Successful Capture And Satellite Tracking Of A West Indian Manatee (Trichechus Manatus) In Panama: Feasibility Of Capture And Telemetry Techniques, Daniel Gonzalez-Socoloske, James P. Reid, Carlos Espinoza-Marin, Kherson E. Ruiz, Kenneth E. Glander, Leon David Olivera-Gomez

Faculty Publications

It is currently unknown how important the Central American countries south of Belize are as a link between manatee populations in the north (Belize and Mexico) and populations in South America. Therefore, apart from knowing where manatees are found, it is important to understand how manatees are using these habitats and if they are moving between countries or distinct population centers. Here we report the results of a multi-national and multiinstitutional collaboration resulting in the first successful capture and satellite tracking of a West Indian manatee in southern Central America.

How Polymorphic Warnings Reduce Habituation In The Brain—Insights From An Fmri Study, Bonnie Brinton Anderson, C. Brock Kirwan, Jeffrey L. Jenkins, David Eargle, Seth Howard, Anthony Vance

Faculty Publications

Research on security warnings consistently points to habituation as a key reason why users ignore security warnings. However, because habituation as a mental state is difficult to observe, previous research has examined habituation indirectly by observing its influence on security behaviors. This study addresses this gap by using functional magnetic resonance imaging (fMRI) to open the “black box” of the brain to observe habituation as it develops in response to security warnings. Our results show a dramatic drop in the visual processing centers of the brain after only the second exposure to a warning, with further decreases with subsequent exposures. …
