Transfer Of The United States National Parasite Collection [Announcement], Eric P. Hoberg, Anna J. Phillips

Harold W. Manter Laboratory of Parasitology: Faculty Publications

In 2013, an agreement was articulated between the United States Department of Agriculture/Agricultural Research Service (ARS) and the Smithsonian Institution to transfer the United States National Parasite Collection in its entirety (fluid specimens, slide specimens, frozen tissues and reprints) to the National Museum of Natural History (NMNH) in Washington, D.C. Current collections staff, including senior curator Dr. Eric P. Hoberg and support scientists/managers from the ARS will be transferred with the collection and with adjunct appointments in the NMNH will provide continuity and assistance for curation and accessibility during and after the relocation. New curatorial controls will be established under …

Anthropogenics: Human Influence On Global And Genetic Homogenization Of Parasite Populations, Dante S. Zarlenga, Eric P. Hoberg, Benjamin Rosenthal, Simonetti Mattiucci, Giuseppe Nascetti

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The distribution, abundance, and diversity of life on Earth have been greatly shaped by human activities. This includes the geographic expansion of parasites; however, measuring the extent to which humans have influenced the dissemination and population structure of parasites has been challenging. In-depth comparisons among parasite populations extending to landscape-level processes affecting disease emergence have remained elusive. New research methods have enhanced our capacity to discern human impact, where the tools of population genetics and molecular epidemiology have begun to shed light on our historical and ongoing influence. Only since the 1990s have parasitologists coupled morphological diagnosis, long considered the …

Rare Earth Dopant (Nd, Gd, Dy, And Er) Hybridization In Lithium Tetraborate, Tony D. Kelly, James C. Petrosky, John W. Mcclory, Volodymyr T. Adamiv, Yaroslav V. Burak, Bohdan V. Padlyak, Ihor M. Teslyuk, Ning Liu, Lu Wang, Wai-Ning Mei, Peter A. Dowben

Peter Dowben Publications

The four dopants (Nd, Gd, Dy, and Er) substitutionally occupy the Li+ sites in lithium tetra borate (Li₂B₄0₇: RE) glasses as determined by analysis of the extended X-ray absorption fine structure. The dopants are coordinated by 6-8 oxygen at a distance of 2.3 to 2.5 A. depending on the rare earth. The inverse relationship between the RE-O coordination distance and rare earth (RE) atomic number is consistent with the expected lanthanide atomic radial contraction with increased atomic number. Through analysis of the X-ray absorption near edge structure, the rare earth dopants adopt the RE …

The Chromium Site In Doped Glassy Lithium Tetraborate, T D. Kelly, E Echeverria, Sumit Beniwal, V T. Adamiv, Ya V. Burak, Axel Enders, J. C. Petrosky, J W. Mcclory, Peter A. Dowben

Peter Dowben Publications

Using extended X-ray absorption fine structure (EXAFS) spectroscopy, we find that Cr substitutes primarily in the Liþ site as a dopant in lithium tetraborate Li₂B₄O₇ glasses, in this case 98.4Li₂B₄O₇e_1.6Cr₂O₃ or nominally Li_1.98Cr_0.025B₄O₇. This strong preference for a single site is nonetheless accompanied by site distortions and some site disorder, helping explain the optical properties of chromium doped Li₂B₄O₇ glasses. The resulting O coordination shell has a contraction of the Cr-O …

Sublattice-Induced Symmetry Breaking And Bandgap Formation In Graphene, Ralph A. Skomski, Peter A. Dowben, M Sky Driver, Jeffery A. Kelber

Peter Dowben Publications

A reduction of symmetry from C_6v to C_3v leads to the opening of a band gap in the otherwise gapless semiconductor graphene. Simple models provide a fairly complete picture of this mechanism for opening a band gap and in fact can be discussed in terms of the tight-binding approximation, accurately resolving the wave-vector space to a very high accuracy. This picture is consistent with experiments that yield a band gap due to A and B graphene-site symmetry breaking due to substrate interactions.

State's Rights, Last Rites, And Voting Rights, Luis Fuentes-Rohwer, Guy-Uriel Charles

Articles by Maurer Faculty

There are two ways to read the Supreme Court's decision in Shelby County Alabama v. Holder: as a minimalist decision or as a decision that undermines the basic infrastructure of voting rights policy, law, and jurisprudence. In this Article, we present the case for reading Shelby County as deeply destabilizing. We argue that Shelby County has undermined three assumptions that are foundational to voting rights policy, law, and jurisprudence. First, the Court has generally granted primacy of the federal government over the states. Second, the Court has deferred to Congress particularly where Congress is regulating at the intersection of race …

Winter Space Use Of Coyotes In High-Elevation Environments: Behavioral Adaptations To Deep-Snow Landscapes, Jennifer L.B. Dowd, Eric M. Gese, Lise M. Aubry

United States Department of Agriculture Wildlife Services: Staff Publications

In the last century, coyotes (Canis latrans) have expanded their range geographically, but have also expanded their use of habitats within currently occupied regions. Because coyotes are not morphologically adapted for travel in deep snow, we studied coyote space use patterns in a deep-snow landscape to examine behavioral adaptations enabling them to use high elevations during winter. We examined the influence of snow depth, snow penetrability, canopy cover, and habitat type, as well as the rates of prey and predator track encounters, on coyote travel distance in high-elevation terrain in northwestern Wyoming, USA. We backtracked 13 radio-collared coyotes for 265.41 …

Bird Use Of Solar Photovoltaic Installations At Us Airports: Implications For Aviation Safety, Travis L. Devault, Thomas W. Seamans, Jason A. Schmidt, Jerrold L. Belant, Bradley F. Blackwell, Nicole Mooers, Laura A. Tyson, Lolita Vanpelt

United States Department of Agriculture Wildlife Services: Staff Publications

Several airports in the US have recently installed large photovoltaic (PV) arrays near air-operations areas to offset energy demands, and the US Federal Aviation Administration has published guidelines for new solar installations on airport properties. Although an increased reliance on solar energy will likely benefit airports from environmental and economic perspectives, bird use of solar installations should be exam-ined before wide-scale implementation to determine whether such changes in land use adversely affect aviation safety by increasing risk of bird-aircraft collisions. We studied bird use of five pairs of PV arrays and nearby airport grasslands in Arizona, Colorado, and Ohio, over …

The Cumulative Effects Of Management On The Population Dynamics Of The Double-Crested Cormorant Phalacrocorax Auritus In The Great Lakes, Alban Guillaumet, Brian S. Dorr, Guiming Wang, Terry J. Doyle

United States Department of Agriculture Wildlife Services: Staff Publications

Wildlife species have been subject to control efforts throughout human history due to real or alleged human-wildlife conflicts. The Double-crested Cormorant Phalacrocorax auritus in the interior of North America is no exception, with recent population growth leading to increased conflicts and consequetly the development of many control programmes. These control programmes are usually conducted at local scales, often with little or no effort to assess their cumulative effects at the population level. We attempted the first comprehensive assessment of the cumulative effects of control at various spatio temporal scales, focusing on 199 colonies of Double-crested Cormorant monitored during a 29-year …

Using Quantitative Disease Dynamics As A Tool For Guiding Response To Avian Influenza In Poultry In The United States Of America, K. M. Pepin, E. Spackman, J. D. Brown, K. L. Pabilonia, Lindsey P. Garber, J. Todd Weaver, D. A. Kennedy, Kelly A. Patyk, K. P. Huyvaert, Ryan S. Miller, Alan B. Franklin, Kerri Pedersen, T. L. Bogich, P. Rohani, Susan A. Shriner, Colleen T. Webb, S. Riley

United States Department of Agriculture Wildlife Services: Staff Publications

Wild birds are the primary source of genetic diversity for influenza A viruses that eventually emerge in poultry and humans. Much progress has been made in the descriptive ecology of avian influenza viruses (AIVs), but contributions are less evident from quantitative studies (e.g., those including disease dynamic models). Transmission between host species, individuals and flocks has not been measured with sufficient accuracy to allow robust quantitative evaluation of alternate control protocols. We focused on the United States of America (USA) as a case study for determining the state of our quantitative knowledge of potential AIV emergence processes from wild hosts …

Longevity Of Rodenticide Bait Pellets In A Tropical Environment Following A Rat Eradication Program, Are R. Berentsen, William C. Pitt, John D. Eisemann, Richard M. Engeman

United States Department of Agriculture Wildlife Services: Staff Publications

Invasive rodents (primarily Rattus spp.) are responsible for loss of biodiversity in island ecosystems worldwide. Large-scale rodenticide applications are typically used to eradicate rats and restore ecological communities. In tropical ecosystems, environmental conditions rapidly degrade baits and competition for baits by non-target animals can result in eradication failure. Our objective was to evaluate persistence of rodenticide baits during a rat eradication program on Palmyra Atoll; a remote tropical atoll with intense competition for resources by land crabs. Following aerial application, bait condition was monitored in four terrestrial environments and in the canopy foliage of coconut palms. Ten circular PVC hoops …

New species records for Bolivia include Tiamastus palpalis and Ectinorus (Panallius) galeanus. New records of fleas from Ctenomys in Bolivia include Gephyropsylla klagesi, Sphinctopsylla inca, and Tetrapsyllus tristis.

Bait Matrix Flavor Preference By Mongoose (Herpestes Auropunctatus) In Puerto Rico: Implications For Oral Rabies Vaccination, Are R. Berentsen, Shylo R. Johnson, Kurt C. Vercauteren

United States Department of Agriculture Wildlife Services: Staff Publications

The small Indian mongoose (Herpestes auropunctatus) is the primary rabies vector in Puerto Rico. Mongooses are implicated in up to 74% of rabies cases on the island, and pose a threat to domestic animals and human health and safety. No rabies management program exists in Puerto Rico and development of an oral rabies vaccination program requires determining which flavors on the vaccine’s bait coating matrix that are attractive to mongooses. Our objective was to evaluate preference among three flavors (cheese, coconut and fish) in the Ultralite bait matrix that is used for delivery of Rabies Vaccine, Live Adenovirus Vector …

Health Policy And The Syrian Chemical Weapons Crisis, David P. Fidler

Articles by Maurer Faculty

For health policy, armed conflicts constitute one of the most severe emergency contexts in which health, well-being, and determinants of health are threatened. The Syrian civil war has proved no different, as health experts re­peatedly lament the humanitarian debacle the Syrian conflict has become. The main distinguishing feature of the Syrian civil war has been the large-scale use of chemical weapons in August 2013. This essay analyzes the chemical weapons crisis and its diplomatic resolution from a health policy perspective, with particular attention on whether the handling of this crisis created positive health policy “spillover” opportunities for more effectively addressing …

Does Habitat Heterogeneity In A Multi-Use Landscape Influence Survival Rates And Density Of A Native Mesocarnivore?, Eric M. Gese, Craig M. Thompson

United States Department of Agriculture Wildlife Services: Staff Publications

The relationships between predators, prey, and habitat have long been of interest to applied and basic ecologists. As a native Great Plains mesocarnivore of North America, swift foxes (Vulpes velox) depended on the historic disturbance regime to maintain open grassland habitat. With a decline in native grasslands and subsequent impacts to prairie specialists, notably the swift fox, understanding the influence of habitat on native predators is paramount to future management efforts. From 2001 to 2004, we investigated the influence of vegetation structure on swift fox population ecology (survival and density) on and around the Pin˜on Canyon Maneuver Site, …

Hazardous Hedging: The (Unacknowledged) Risks Of Hedging With Credit Derivatives, Gina-Gail S. Fletcher

Articles by Maurer Faculty

Is hedging with credit derivatives always beneficial? The benefit of hedging with credit derivatives, such as credit default swaps, is presumed by the Dodd-Frank Act, which excludes hedge transactions from much of the new financial regulation. Yet, new, significant risks can arise when credit derivatives are used to manage risks. Hedging, therefore, should be defined not only in relation to whether a transaction offsets risks, but also whether, on balance, the risks that are mitigated, as well as any new risks that arise, are outweighed by the potential benefits.

Firms using credit derivatives to hedge often fail to account for …

When Churches Reorganize, Pamela Foohey

Articles by Maurer Faculty

The article complements and expands the author’s prior article, Bankrupting the Faith. This article primarily relies on interviews with attorneys who represented religious organizations in chapter 11 bankruptcy to assess whether reorganization has the potential to offer an effective solution to religious organizations’ financial problems. In doing so, it makes three contributions. First, it tracks the post-bankruptcy outcomes of a portion of the debtors to find that approximately 65% remained operating post-bankruptcy; these outcomes contradict previous studies of small business bankruptcy and are important to current debates about reforming small business bankruptcy. Given this—and in keeping with the ABLJ’s …

An Amino Acid-Electrolyte Beverage May Increase Cellular Rehydration Relative To Carbohydrate-Electrolyte And Flavored Water Beverages, Chin-Yin Tai, Jordan M. Joy, Paul H. Falcone, Laura R. Carson, Matt M. Momsman, Justen L. Straight, Susie L. Oury, Carlos Mendez Jr, Nick L. Loveridge, Michael P. Kim, Jordan R. Moon

Department of Nutrition and Health Sciences: Faculty Publications

Background: In cases of dehydration exceeding a 2% loss of body weight, athletic performance can be significantly compromised. Carbohydrate and/or electrolyte containing beverages have been effective for rehydration and recovery of performance, yet amino acid containing beverages remain unexamined. Therefore, the purpose of this study is to compare the rehydration capabilities of an electrolyte-carbohydrate (EC), electrolyte-branched chain amino acid (EA), and flavored water (FW) beverages. Methods: Twenty men (n = 10; 26.7 ± 4.8 years; 174.3 ± 6.4 cm; 74.2 ± 10.9 kg) and women (n = 10; 27.1 ± 4.7 years; 175.3 ± 7.9 cm; 71.0 ± 6.5 kg) …

Effectiveness Of Tailored Lifestyle Interventions, Using Web-Based And Print-Mail, For Reducing Blood Pressure Among Rural Women With Prehypertension: Main Results Of The Wellness For Women: Dashing Towards Health Clinical Trial, Patricia A. Hageman, Carol H. Pullen, Melody Hertzog, Linda S. Boeckner

Department of Nutrition and Health Sciences: Faculty Publications

Background: Lifestyle modification is recommended for management of prehypertension, yet finding effective interventions to reach rural women is a public health challenge. This community-based clinical trial compared the effectiveness of standard advice to two multi-component theory-based tailored interventions, using web-based or print-mailed delivery, in reducing blood pressure among rural women, ages 40–69, with prehypertension.

Methods: 289 women with prehypertension enrolled in the Wellness for Women: DASHing towards Health trial, a 12-month intervention with 12-month follow-up. Women were randomly assigned to groups using a 1:2:2 ratio, comparing standard advice (30-minute counseling session) to two interventions (two 2-hour counseling sessions, …

Dietary Cholesterol Promotes Adipocyte Hypertrophy And Adipose Tissue Inflammation In Visceral, But Not Subcutaneous, Fat In Monkeys, Soonkyu Chung, Helen Cuffe, Stephanie M. Marshall, Allison L. Mcdaniel, Jung-Heun Ha, Kylie Kavanagh, Cynthia Hong, Peter Tontonoz, Ryan E. Temel, John S. Parks

Department of Nutrition and Health Sciences: Faculty Publications

Objective—Excessive caloric intake is associated with obesity and adipose tissue dysfunction. However, the role of dietary cholesterol in this process is unknown. The aim of this study was to determine whether increasing dietary cholesterol intake alters adipose tissue cholesterol content, adipocyte size, and endocrine function in nonhuman primates.

Approach and Results—Age-matched, male African Green monkeys (n=5 per group) were assigned to one of three diets containing 0.002 (Lo), 0.2 (Med) or 0.4 (Hi) mg cholesterol/Kcal. After 10 weeks of diet feeding, animals were euthanized for adipose tissue, liver, and plasma collection. With increasing dietary cholesterol, free cholesterol (FC) content and …

Aborted Emotions: Regret, Relationality, And Regulation, Jody L. Madeira

Articles by Maurer Faculty

Regret is a deeply contested emotion within abortion discourse. It is present in ways that we are both afraid of and afraid to talk about. Conventional pro-life and pro-choice narratives link regret to defective decision making. Both sides assert that the existence of regret reveals abortion’s harmfulness or harmlessness, generating a narrow focus on the maternal-fetal relationship and women’s “rights.”These incomplete, deeply flawed constructions mire discourse in a clash between regret and relief and exclude myriad relevant relationships. Moreover, they distort popular understandings of abortion that in turn influence women, creating cognitive dissonance and perhaps distress for those with different …

A Retrospective Examination Of Paleoparasitology And Its Establishment In The Journal Of Parasitology, Charles T. Faulkner, Karl Reinhard

School of Natural Resources: Faculty Publications

Volume 95 (2009) of the Journal of Parasitology represented a significant benchmark in the history of paleoparasitology when it received on the cover formal recognition as a topical area for publication. This retrospective examination chronicles the emergence of paleoparasitology, from its origins as an adjunct contribution to the study of prehistoric human populations to its modern expression as a sub-disciplinary interest. The aim of paleoparasitology is to elucidate the temporal and spatial dimensions of parasitism from the fossil record of human and non-human host populations.

Uncovering The Nuances Of Referral Hiring: How Referrer Characteristics Affect Referral Hires’ Performance And Likelihood Of Voluntary Turnover, Jenna R. Pieper

Department of Management: Faculty Publications

The literature on employee referral hiring gives little attention to referrers. Synthesizing two theories in the literature (the better match and social enrichment accounts), through the lens of social resources theory, I provide a conceptual and empirical breakdown of the effects of referrer quality (referrer performance at hire and referrer tenure at hire) and post-hire accessibility (referrer employment and referrer-referral hire job congruence) on referral hire performance and likelihood of voluntary turnover. I tested my hypotheses with longitudinal data from 386 referrer-referral hire pairs at the same job level in a U.S. call center over a 2-year period. Across analyses …

Cenomanian Through Basal Coniacian Calcareous Nannofossil Biostratigraphy Of Themancos Shale Reference Section, Mesa Verde National Park, Co, Matthew J. Corbett, David K. Watkins

Department of Earth and Atmospheric Sciences: Faculty Publications

Upper Cenomanian through lower Coniacian calcareous nannofossil biostratigraphy is integrated with macrofossil and lithostratigraphic correlations at the reference section for the Mancos Shale in Mesa Verde National Park, CO. Interpretations of key biostratigraphic events and δ¹³C values from bulk-rock carbonate fit well with the placement of stage boundaries by Leckie et al. (1997) and observations of nannofossil biostratigraphy in equivalent successions in the Western Interior. Tethyan nannofossil zone CC10b brackets the Cenomanian-Turonian boundary between 22.7–27.6m. Anannofossil zonal boundary between CC13 and CC14 is placed at 200.4-201m supporting the existence of an unconformity in the basal Smoky Hill Member …
