A Geospatial Approach To Identify Water Quality Issues For National Wildlife Refuges In Oregon And Washington, Jo Ellen Hinck, Kimberly Chojnacki, Susan Finger, Greg Linder, Kevin Kilbride

United States Geological Survey: Staff Publications

Many National Wildlife Refuges (Refuges) have impaired water quality resulting from historic and current land uses, upstream sources, and aerial pollutant deposition. Competing duties limit the time available for Refuge staff to identify and evaluate potential water quality issues. As a result, water quality–related issues may not be resolved until a problem has already arisen. This study developed a geospatial approach for identifying and prioritizing water quality issues affecting natural resources (including migratory birds and federally listed species) within Refuge boundaries. We assessed the location and status of streams pursuant to the Clean Water Act in relation to individual Refuges …

Smooth Brome (Bromus Inermis Leyss) And Soil Chemical Response To Concrete Grinding Residue Application, Tom Desutter, Patricia Goosen-Alix, Lyle Prunty, Paul White Jr., Frank Casey

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Concrete grinding residue (CGR) is a byproduct created by concrete pavement maintenance operations. The application of CGR to roadside soils is not consistently regulated by state agencies across the USA, which is partially due to the lack of science-based information on its impacts to soils and plants. The objectives of this research were to determine the impact of CGR additions to soil on both smooth brome (Bromus inermis L.) biomass and plant and soil chemical parameters. In a greenhouse study, two soils were treated with two CGR by-products at 8% and 25% by weight. Shoot biomass was significantly influenced …

Susceptibility Of Selected Potato Varieties To Zebra Chip Potato Disease, Joseph E. Munyaneza, Jeremy L. Buchman, Venkatesan G. Sengoda, Tonja W. Fisher, Cole C. Pearson

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Zebra chip (ZC), an emerging and serious disease of potato has caused millions of dollars in losses to the potato industry in the United States, Mexico, Central America, and New Zealand. The disease has recently been associated with a previously undescribed species of liberibacter tentatively named “Candidatus Liberibacter solanacearum” transmitted to potato by the potato psyllid, Bactericera cockerelli (Šulc). At present, applications of insecticides targeted against the potato psyllid are the only means to manage ZC. Given the low psyllid density and short inoculation access period required to induce the disease, insecticides may not act fast enough to prevent …

Challenges Of Predicting The Potential Distribution Of A Slow-Spreading Invader: A Habitat Suitability Map For An Invasive Riparian Tree, Catherine S. Jarnevich, Lindsay V. Reynolds

United States Geological Survey: Staff Publications

Understanding the potential spread of invasive species is essential for land managers to prevent their establishment and restore impacted habitat. Habitat suitability modeling provides a tool for researchers and managers to understand the potential extent of invasive species spread. Our goal was to use habitat suitability modeling to map potential habitat of the riparian plant invader, Russian olive (Elaeagnus angustifolia). Russian olive has invaded riparian habitat across North America and is continuing to expand its range. We compiled 11 disparate datasets for Russian olive presence locations (n = 1,051 points and 139 polygons) in the western US and …

Evaluating The Effect Of Predators On White-Tailed Deer: Movement And Diet Of Coyotes, Melissa M. Turner, Aimee P. Rockhill, Christopher S. Deperno, Jonathan A. Jenks, Robert W. Klaver, Angela R. Jarding, Troy W. Grovenburg, Kenneth H. Pollock

United States Geological Survey: Staff Publications

Coyotes (Canis latrans) may affect adult and neonate white-tailed deer (Odocoileus virginianus) survival and have been implicated as a contributor to the decline of deer populations. Additionally, coyote diet composition is influenced by prey availability, season, and region. Because coyote movement and diet vary by region, local data are important to understand coyote population dynamics and their impact on prey species. In southeast Minnesota, we investigated the effect of coyotes on white-tailed deer populations by documenting movement rates, distances moved, and habitats searched by coyotes during fawning and nonfawning periods. Additionally, we determined survival, cause-specific mortality, …

Introduction To “Environmental Contaminants In Biota, 2nd Edition”, W. Nelson Beyer, James P. Meador

United States Geological Survey: Staff Publications

Ecotoxicology is the study of the movement of environmental contaminants through ecosystems and their effects on plants and animals. Examining tissue residues of these contaminants in biota is basic to ecotoxicology, both for understanding the movement of contaminants within organisms and through food chains, and for understanding and quantifying injuries to organisms and their communities. This book provides guidance on interpreting tissue concentrations of environmental contaminants.

Tissue concentrations have long been used both to identify the cause of toxicity in animals and as a measure of the severity of toxicity. More recently, they have been incorporated into environmental models, tying …

Lead In Birds, J. Christian Franson, Deborah J. Pain

United States Geological Survey: Staff Publications

Lead is a highly toxic heavy metal that acts as a nonspecific poison affecting all body systems and has no known biological requirement. Absorption of low concentrations may result in a wide range of sublethal effects in animals, and higher concentrations may result in mortality (Demayo et al. 1982).

Lead has been mined and smelted by humans for centuries, but the use of lead-based products increased greatly following the Industrial Revolution. Consequently, lead today is ubiquitous in air, water, and soil, in both urban and rural environments (Eisler 2000). Vertebrates are exposed to lead mainly via inhalation and ingestion. A …

Correlation Of Omega-3 Fatty Acids Intakes With Acculturation And Socioeconomic Status In Midwestern Latinas, Karina R. Lora, Nancy M. Lewis, Kent M. Eskridge, Kaye Stanek-Krogstrand, Daryl A. Travnicek

Department of Nutrition and Health Sciences: Faculty Publications

Background: Low socioeconomic status (SES) and acculturation of Latino immigrants in the U.S. are linked to a decrease in diet quality. Methods: Interviews were conducted with 162 first-generation Latinas to examine the association of SES and acculturation with intake of omega-3 (n − 3) fatty acids. Each participant provided dietary intake by use of a validated n − 3 food frequency questionnaire administered twice, 4 weeks apart, three 24-h recalls, sociodemographic information and completed the 5-item Short Acculturation Scale. Results: Mean intakes of Total n − 3, α-linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) (g/d) were …

The Role Of Histone H4 Biotinylation In The Structure Of Nucleosomes, Nina A. Filenko, Carol Kolar, John T. West, S. Abbie Smith, Yousef I. Hassan, Gloria E. O. Borgstahl, Janos Zempleni, Yuri L. Lyubchenko

Department of Nutrition and Health Sciences: Faculty Publications

Background: Post-translational modifications of histones play important roles in regulating nucleosome structure and gene transcription. It has been shown that biotinylation of histone H4 at lysine-12 in histone H4 (K12Bio-H4) is associated with repression of a number of genes. We hypothesized that biotinylation modifies the physical structure of nucleosomes, and that biotin-induced conformational changes contribute to gene silencing associated with histone biotinylation.

Methodology/Principal Findings: To test this hypothesis we used atomic force microscopy to directly analyze structures of nucleosomes formed with biotin-modified and non-modified H4. The analysis of the AFM images revealed a 13% increase in the length of …

Body Mass Index Is Associated With Dietary Patterns And Health Conditions In Georgia Centenarians, Dorothy B. Hausman, Mary Ann Johnson, Adam Davey, Leonard W. Poon

Department of Nutrition and Health Sciences: Faculty Publications

Associations between body mass index (BMI) and dietary patterns and health conditions were explored in a population-based multiethnic sample of centenarians from northern Georgia. BMI ≤20 and ≥25 was prevalent in 30.9% and 25.3% of study participants, respectively. In a series of logistic regression analyses controlled for gender and place of residence, the probability of having BMI ≥25 was increased by being black versus white and having a low citrus fruit, noncitrus fruit, orange/yellow vegetable or total fruit and vegetable intake. The probability of having BMI ≤20 was not associated with dietary intake. When controlled for race, gender, residence, and …

A Field Evaluation Of A Trap For Invasive American Bullfrogs, Nathan P. Snow, Gary W. Witmer

United States Department of Agriculture Wildlife Services: Staff Publications

Native to the eastern United States, American bullfrogs (Rana catesbeiana [Lithobates catesbeianus]) have been introduced in many countries throughout the world. There have been relatively few effective and efficient control methods developed to manage bullfrogs. Particularly in the Hawaiian Islands, Pacific coast of North America, and Japan, finding effective methods for controlling invasive bullfrogs is needed with special emphasis on low impacts for sensitive native species. We conducted a field study to examine the efficacy of a newly designed live trap for capturing invasive bullfrogs. We found that our trap was successful at capturing bullfrogs because we …

Adaptive Resource Management And The Value Of Information, Byron K. Williams, Mitchell J. Eaton, David R. Breininger

United States Geological Survey: Staff Publications

The value of information is a general and broadly applicable concept that has been used for several decades to aid in making decisions in the face of uncertainty. Yet there are relatively few examples of its use in ecology and natural resources management, and almost none that are framed in terms of the future impacts of management decisions. In this paper we discuss the value of information in a context of adaptive management, in which actions are taken sequentially over a timeframe and both future resource conditions and residual uncertainties about resource responses are taken into account. Our objective is …

Pathology, East Africa

Background: Verbal autopsy methods are critically important for evaluating the leading causes of death in populations without adequate vital registration systems. With a myriad of analytical and data collection approaches, it is essential to create a high quality validation dataset from different populations to evaluate comparative method performance and make recommendations for future verbal autopsy implementation. This study was undertaken to compile a set of strictly defined gold standard deaths for which verbal autopsies were collected to validate the accuracy of different methods of verbal autopsy cause of death assignment.

Methods: Data collection was implemented in six sites in four …

Relationships Between High-Stakes Clinical Skills Exam Scores And Program Director Global Competency Ratings Of First-Year Pediatric Residents, E. E. Langenau, G. Pugliano, W. L. Roberts

PCOM Scholarly Works

An Upper Limit For Macromolecular Crowding Effects, Andrew C. Miklos, Congang Li, Courtney D. Sorell, L. Andrew Lyon, Gary J. Pielak

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Background: Solutions containing high macromolecule concentrations are predicted to affect a number of protein properties compared to those properties in dilute solution. In cells, these macromolecular crowders have a large range of sizes and can occupy 30% or more of the available volume. We chose to study the stability and ps-ns internal dynamics of a globular protein whose radius is similar to 2 nm when crowded by a synthetic microgel composed of poly(N-isopropylacrylamide-co-acrylic acid) with particle radii of similar to 300 nm.

Results: Our studies revealed no change in protein rotational or ps-ns backbone dynamics and only mild …

Modulation Of Myocardial Mitochondrial Mechanisms During Severe Polymicrobial Sepsis In The Rat, M. Chopra, H. B. Golden, S. Mullapudi, W. Dowhan, D. E. Dostal, Avadhesh C. Sharma

PCOM Scholarly Works

Background: We tested the hypothesis that 5-Hydroxydecanoic acid (5HD), a putative mitoKATP channel blocker, will reverse sepsis-induced cardiodynamic and adult rat ventricular myocyte (ARVM) contractile dysfunction, restore mitochondrial membrane permeability alterations and improve survival. Methodology/Principal Findings: Male Sprague-Dawley rats (350-400 g) were made septic using 400 mg/kg cecal inoculum, ip. Sham animals received 5% dextrose water, ip. The Voltage Dependent Anion Channels (VDAC1), Bax and cytochrome C levels were determined in isolated single ARVMs obtained from sham and septic rat heart. Mitochondria and cytosolic fractions were isolated from ARVMs treated with norepinephrine (NE, 10 µmoles) in the presence/absence of 5HD …

Comparing Species And Ecosystem-Based Estimates Of Fisheries Yields, John H. Steele, Dian J. Gifford, Jeremy S. Collie

Graduate School of Oceanography Faculty Publications

Three methods are described to estimate potential yields of commercial fish species: (i) single-species calculation of maximum sustainable yields, and two ecosystem-based methods derived from published results for (ii) energy flow and for (iii) community structure. The requirements imposed by food-web fluxes, and by patterns of relative abundance, provide constraints on individual species. These constraints are used to set limits to ecosystem-based yields (EBY); these limits, in turn, provide a comparison with the usual estimates of maximum sustainable yields (MSY). We use data on cod and haddock production from Georges Bank for the decade 1993–2002 to demonstrate these methods. We …

Financial Literacy Or Financial Castigation?, John A. E. Pottow

Articles

This year, the Canadians- through their government-convened Task Force on Financial Literacy - have proudly produced, "Canadians and their Money: Building a Brighter Financial Future." Armed with 30 recommendations, its most dramatic innovation is to recommend the creation of a Financial Literacy Leader. I have been asked to provide an American perspective on this report specifically and the broader agenda of "financial literacy" more generally as a consumer welfare intervention. Let me start by acknowledging the critiques of the Canadian Task Force. For example, my Canadian colleague, Saul Schwartz, has already drafted a compelling analysis of the political economy behind …

Malpractice Suits And Physician Apologies In Cancer Care, Eugene Chung, Jill R. Horwitz, John A.E. Pottow, Reshma Jagsi

Articles

Conside the following case: The patient is a 44-year-old woman who presents for radiation treatment of an isolated locoregional recurrence of breat cancer in her chest wall, 3 years after undergoing masectomy. At the time of diagnosis, she had T2N2M0 disease, with four of 15 lymph nodes involved with tumor. She received a masectomy with negative margins and appropriate chemotherapy, but none of her physicians talked to her about postmasectomy radiation therapy, which would clearly have been indicated to reduce her risk of locoregional failure and would have been expected to improve her likelihood of survival. She asks the radiation …

Losing It, William I. Miller

Articles

You are in your sixties, even fifties, and you are walking by a shop window, or in some area in which a security monitor shows a scan of the line you are in. You sneak a look. You see someone in the space where you should be but you do not recognize the interloper. Then, after an unseemly lag of a second or two you are forced to remake your own acquaintance; it seems you no longer know yourself at first sight. The you behind your eyes believes you look like you did twenty years ago, and it assumes that …

Nevada County’S Assisted Outpatient Treatment Program: A Model For Other California Counties To Adopt?, Ralph J. Murrieta Jr.

Master's Projects

In May 2008, Nevada County became the first county in California to fully implement an Assisted Outpatient Treatment (AOT) program under the guidelines established by Assembly Bill 1421 (Keller, 2011). The Assisted Outpatient Treatment Demonstration Project Act of 2002, more commonly known as “Laura’s Law”, established guidelines for the court ordering of treatment for persons incapacitated by a mental disorder (California Department of Mental Health [CA DMH], 2003).

Passed in September 2002, the bill was highly controversial leading up to its passage and remains a very divisive issue today (Fagan, 2010). This paper will focus on the provisions of the …

Confidentiality Explained: The Dialogue Approach To Discussing Confidentiality With Clients, Elisia M. Klinka, Russell G. Pearce

Faculty Scholarship

Many lawyers lie to their clients by saying, “Everything you tell me is confidential” despite the existence of some rules that require lawyers to disclose client confidences and others that permit lawyers to disclose confidences to protect themselves or collect fees. In an effort to encourage clients to speak honestly, a number of commentators urge lawyers to provide either a general or specific notice of the exceptions to confidentiality. This Article offers a different approach. It seeks to promote an honest and open dialogue between lawyer and client that will create a relationship of mutual trust and will make it …

Student Preferences In Library Website Vocabulary, Mark Aaron Polger

Publications and Research

This study explores student preferences to library website vocabulary and compares the data with what librarians report on their library's website. Two questionnaires were distributed in the fall of 2009 to students (N=300) and librarians (N=527). Students were asked to identify the terms they prefer from a larger list of library website vocabulary. Librarians were asked to report the terms that were used on their library's website. Twenty-seven terms were selected for both the student and librarian questionnaires. The 27 terms were culled from library literature, library instruction classes, and reference desk interactions. Of the 300 students, 54% were freshmen, …

Linking Cd Accumulation And Effect In Resistant And Sensitive Freshwater Invertebrates, Tony Straus

Theses and Dissertations (Comprehensive)

There has been recent discussion within the field of environmental toxicology as to the viability of using the bioaccumulation of a chemical toxicant to predict toxic effects. Current literature has shown this concept to carry some merit, although there is a major flaw in that with many cases, namely those involving sensitive species, body burdens cannot be reliably linked to effects (Adams et al. (2010)). Bearing this issue in mind the goal of this thesis was to assess the viability of using bioaccumulation as a measure of effect in a different way.

The proposed idea utilized Cd accumulation in a …

Effective Islamic Spiritual Care: Foundations And Practices Of Imams And Other Muslim Spiritual Caregivers, Nazila Isgandarova

Theses and Dissertations (Comprehensive)

In Canada, Muslim communities turn to Muslim spiritual caregivers, especially to imams, for help with various problems. Research has shown that many Muslim spiritual caregivers are familiar with the Arabic language and Islamic values but have limited practice in Islamic counseling and psychotherapy. This study is intended to examine the effectiveness of Muslim spiritual caregivers in the context of Canadian Muslims’ health care. Cross-sectional ethnographic research with fifteen Muslim spiritual caregivers and interviews with them were conducted.

Our results show that even though the majority of Muslim spiritual caregivers have no formal training in Western psychotherapy intervention, they nonetheless play …

Exegetical And Extispicic Readings Of The Bible In Turkana, Kenya, And North America, Kevin P. Lines

The Asbury Journal

While a missional hermeneutic elucidates missiological interpretation of scripture, translation would be the key descriptive of missiological me of scripture. Articulating, a Turkana extispicic hermeneutic as both a critical and a valid process for interpreting the Bible, this paper proposes that Christians have the opportunity to engage in alternative intercontextual critical hermeneutical processes when "reading" the Bible. This engagement could reveal an ontic expansion of God-if we are able to overcome eclectic diversity and the fear of relativism. Three locations: theological institutions, missionaries, in the church, and diaspora communities are suggested for practical application of intercontextual hermeneutics.
