Highly Selective Gas Sensor Arrays Based On Thermally Reduced Graphene Oxide, Alexey Lipatov, Alexey Varezhnikov, Peter Wilson, Victor Sysoev, Andrei Kolmakov, Alexander Sinitskii

Department of Chemistry: Faculty Publications

The electrical properties of reduced graphene oxide (rGO) have been previously shown to be very sensitive to surface adsorbates, thus making rGO a very promising platform for highly sensitive gas sensors. However, poor selectivity of rGO-based gas sensors remains a major problem for their practical use. In this paper, we address the selectivity problem by employing an array of rGO-based integrated sensors instead of focusing on the performance of a single sensing element. Each rGO-based device in such an array has a unique sensor response due to the irregular structure of rGO films at different levels of organization, ranging from …

The Influence Of Audibility On Speech Recognition With Nonlinear Frequency Compression For Children And Adults With Hearing Loss, Ryan W. Mccreery, Joshua Alexander, Marc A. Brennan, Brenda Hoover, Judy Kopun, Patricia G. Stelmachowicz

Department of Special Education and Communication Disorders: Faculty Publications

Objective—The primary goal of nonlinear frequency compression (NFC) and other frequency lowering strategies is to increase the audibility of high-frequency sounds that are not otherwise audible with conventional hearing-aid processing due to the degree of hearing loss, limited hearing aid bandwidth or a combination of both factors. The aim of the current study was to compare estimates of speech audibility processed by NFC to improvements in speech recognition for a group of children and adults with high-frequency hearing loss.

Design—Monosyllabic word recognition was measured in noise for twenty-four adults and twelve children with mild to severe sensorineural hearing loss. Stimuli …

Phonological And Lexical Influences On Phonological Awareness In Children With Specific Language Impairment And Dyslexia, Kelly Farquharson, Tracy M. Centanni, Chelsea E. Franzluebbers, Tiffany Hogan

Department of Special Education and Communication Disorders: Faculty Publications

Children with dyslexia and/or specific language impairment have marked deficits in phonological processing, putting them at an increased risk for reading deficits. The current study sought to examine the influence of word-level phonological and lexical characteristics on phonological awareness. Children with dyslexia and/or specific language impairment were tested using a phoneme deletion task in which stimuli differed orthogonally by sound similarity and neighborhood density. Phonological and lexical factors influenced performance differently across groups. Children with dyslexia appeared to have a more immature and aberrant pattern of phonological and lexical influence (e.g., favoring sparse and similar features). Children with SLI performed …

Tier 3 Intervention: Discipline Recovery, Reece L. Peterson, Ann O'Connor, Jenna Strawhun

Department of Special Education and Communication Disorders: Faculty Publications

Conclusion

Clearly, further research on discipline recovery and education programs for students that have been expelled is warranted. Several states and programs appear to be making strides in providing students opportunities to accumulate credits and/or prepare for the workforce while expelled from public school, and clearly this is better than no such programs. However, there is little formal evidence to support or guide specific implementation or programming details for these types programs.

The Effect Of Answering In A Preferred Versus A Non-Preferred Survey Mode On Measurement, Jolene Smyth, Kristen Olson, Alian S. Kasabian

Department of Sociology: Faculty Publications

Previous research has shown that offering respondents their preferred mode can increase response rates, but the effect of doing so on how respondents process and answer survey questions (i.e., measurement) is unclear. In this paper, we evaluate whether changes in question format have different effects on data quality for those responding in their preferred mode than for those responding in a non-preferred mode for three question types (multiple answer, open-ended, and grid). Respondents were asked about their preferred mode in a 2008 survey and were recontacted in 2009. In the recontact survey, respondents were randomly assigned to one of two …

Department of Sociology: Faculty Publications

Objective—Our objective was to investigate change in prevalence rates for mental and substance abuse disorders between early adolescence and young adulthood in a cohort of indigenous adolescents who participated in an 8-year panel study.

Method—The data are from a lagged, sequential study of 671 indigenous adolescents (Wave 1) from a single culture in the Northern Midwest USA and Canada. At Wave 1 (mean age 11.3 years, Wave 4 (mean age 14.3 years), Wave 6 (mean age 16.2 years), and at Wave 8 (mean age 18.3 years) the tribally enrolled adolescents completed a computer-assisted personal interview that included DISC-R assessment for …

Safety And Immunogenicity Of Ontario Rabies Vaccine Bait (Onrab) In The First Us Field Trial In Raccoons (Procyon Lotor), Dennis Slate, Richard B. Chipman, Timothy P. Algeo, Samuel A. Mills, Kathleen M. Nelson, Christopher K. Croson, Edward J. Dubovi, Kurt C. Vercauteren, Randall W. Renshaw, Todd Atwood, Shylo Johnson, Charles E. Rupprecht

United States Department of Agriculture Wildlife Services: Staff Publications

In 2011, we conducted a field trial in rural West Virginia, USA to evaluate the safety and immunogenicity of a live, recombinant human adenovirus (AdRG1.3) rabies virus glycoprotein vaccine (Ontario Rabies Vaccine Bait; ONRAB) in wild raccoons (Procyon lotor) and striped skunks (Mephitis mephitis). We selected ONRAB for evaluation because of its effectiveness in raccoon rabies management in Ontario and Quebec, Canada, and significantly higher antibody prevalence rates in raccoons compared with a recombinant vaccinia-rabies glycoprotein (V-RG) vaccine, Raboral V-RGH, in US–Canada border studies. Raccoon rabies was enzootic and oral rabies vaccination (ORV) had never been …

Use Of Eu Institutions Outside The Eu Legal Framework: Foundations, Procedure And Substance, Paul Craig

Articles by Maurer Faculty

The decision in Case Pringle was primarily concerned with whether the European Stability Mechanism (TFEU) was compatible with various substantive provisions of the Treaty on the Functioning of the European Union, most notably the prohibition on bailouts in Article 125 TFEU. The judgment is nonetheless important for other reasons, including the legitimacy of the use of EU institutions outside the EU legal framework. It will be seen that the CJEU endorsed their use and reaffirmed earlier case law. These conclusions were analysed by Steve Peers in a helpful article in a previous issue of the European Constitutional Law Review, in …

Let Us Rank Journalism Programs, Joseph Weber

College of Journalism and Mass Communications: Faculty Publications

Unlike law, business, and medical schools, as well as universities in general, journalism schools and journalism programs have rarely been ranked. Publishers such as U.S. News & World Report, Forbes, Bloomberg Businessweek, and Washington Monthly do not pay them much mind. What is the best journalism school in the country? The top ten undergraduate and graduate schools? It is impossible to know. That should change, and the Association for Education in Journalism and Mass Communication (AEJMC) should lead the way. It should develop a ranking system that would be helpful to anyone interested, especially because federal policy makers soon will …

A Landscape-Based Approach For Delineating Hotspots Of Wildlife-Vehicle Collisions, Nathan P. Snow, David M. Williams, William F. Porter

United States Department of Agriculture Wildlife Services: Staff Publications

Imposing human perceptions about the scales of ecological processes can produce unreliable scientific inferences in wildlife research and possibly misinform mitigation strategies. An example of this disconnect occurs in studies of wildlife-vehicle collisions (WVCs). Subjective procedures are often used to delineate hotspots of WVCs, resulting in hotspots that are not spatially independent. We developed a new approach that identifies independent hotspots using attributes of the landscape to inform delineations instead of subjective measures. First, we generated a candidate set of grouping scenarios using unique combinations of kernel-density estimation parameterization (i.e., bandwidth and isopleth values). Next, we associated the groups of …

Ryan Jash, Sonja Weiss, Stanley Langevin, Harry M. Savage, Marvin S. Godsey Jr., Kristen Burkhalter, J. Jeffrey Root, Thomas Gidlewski, William L. Nicholson, Aaron C. Brault, Nicholas Komar

United States Department of Agriculture Wildlife Services: Staff Publications

We describe the isolation of West Nile virus (WNV; Flaviviridae, Flavivirus) from blood of a Virginia opossum (Didelphis virginiana) collected in northwestern Missouri, USA in August 2012. Sequencing determined that the virus was related to lineage 1a WNV02 strains. We discuss the role of wildlife in WNV disease epidemiology.

An Agent-Based Movement Model To Assess The Impact Of Landscape Fragmentation On Disease Transmission, Jeff A. Tracey, Sarah N. Bevins, Sue Vandewoude, Kevin R. Crooks

United States Department of Agriculture Wildlife Services: Staff Publications

Landscape changes can result in habitat fragmentation and reduced landscape connectivity, limiting the ability of animals to move across space and altering infectious disease dynamics in wildlife. In this study, we develop and implement an agent-based model to assess the impacts of animal movement behavior and landscape structure on disease dynamics. We model a susceptible/infective disease state system applicable to the transmission of feline immunodeficiency virus in bobcats in the urbanized landscape of coastal southern California. Our agent-based model incorporates animal movement behavior, pathogen prevalence, transmission probability, and habitat fragmentation to evaluate how these variables influence disease spread in urbanizing …

Memory-Based Quantity Discrimination In Coyotes (Canis Latrans), Salif Mahamane, Kevin L. Grunig, Joseph Baker, Julie K. Young, Kerry E. Jordan

United States Department of Agriculture Wildlife Services: Staff Publications

Previous research has shown that the ratio between competing quantities of food significantly mediates coyotes‘ (Canis latrans) ability to choose the larger of two food options. These previous findings are consistent with predictions made by Weber‘s Law and indicate that coyotes possess quantity discrimination abilities that are similar to other species. Importantly, coyotes‘ discrimination abilities are similar to domestic dogs (Canis lupus familiaris), indicating that quantitative discrimination may remain stable throughout certain species‘ evolution. However, while previously shown in two domestic dogs, it is unknown whether coyotes possess the ability to discriminate visual quantities from memory. …

Disease Risks ·Posed By Wild Birds Associated With Agricultural Landscapes, Larry Clark

United States Department of Agriculture Wildlife Services: Staff Publications

There are over 1,400 cataloged human pathogens, with approximately 62% classified as zoonotic (Taylor et aI., 2001). While most evidence of direct transmission of pathogens to humans involves domestic and companion animals, the reservoir for most zoonoses is wildlife, yet there are relatively few well-documented cases for the direct involvement of transmission from wildlife to humans (Kruse et aI., 2004). In part, this absence of evidence reflects the mobility of wildlife, the difficulty in accessing relevant samples, and the smaller number of studies focused on characterizing wildlife pathogens relative to the human and veterinary literature (McDiarmid, 1969; Davies et aI., …

How Should Governments Promote Distributive Justice?: A Framework For Analyzing The Optimal Choice Of Tax Instruments, David Gamage

Articles by Maurer Faculty

A particular methodology derived from public finance economics has become very influential in the legal literature on taxation and related topics. Sometimes called the “double-distortion” approach, this methodology forms the heart of Louis Kaplow’s book “The Theory of Taxation and Public Economics” and is also the foundation of prominent work by other leading tax legal scholars such as David Weisbach and James Hines.

This Article develops an extended critique of how the double-distortion approach has been used to make legal policy arguments. In doing so, this Article constructs a framework for analyzing how governments can optimally raise revenues and promote …

Environmental Salmonella In Agricultural Fair Poultry Exhibits In Colorado, K. L. Pabilonia, K. J. Cadmus, T. M. Lingus, D. S. Bolte, M. M. Russell, D. C. Van Metre, M. M. Erdman

United States Department of Agriculture Wildlife Services: Staff Publications

Salmonella enterica is a common zoonotic pathogen in humans. Transmission typically occurs through consumption of contaminated food products or contact with infected animals, including poultry or their environment. The objective of this study was to estimate the frequency of Salmonella contamination in the environment in poultry exhibits at agricultural fairs. Samples were collected from cages, feed, floors and tables in the exhibit and cultured for Salmonella. At least one environmental sample was positive for Salmonella in 10 of 11 fairs (91%), and Salmonella was isolated from 28 of 55 environmental samples (50.9%). Eleven different serotypes were detected. Results of …

Novel Management Methods: Immunocontraception And Other Fertility Control Tools, Giovanna Massei, Dave Cowan, Douglas C. Eckery

United States Department of Agriculture Wildlife Services: Staff Publications

Impacts of overabundant ungulate populations on human activities and conservation include crop and forestry losses, collisions with vehicles, disease transmission, nuisance behaviour, damage to infrastructures, predation on livestock and native species, and reduction of biodiversity in plant and animal communities (e.g. Curtis et ai., 2002; Massei et al., 2011; Reimoser and Putman, 2011; Ferroglio et ai., 2011; Langbein et al., 2011). Current trends in human population growth and landscape development indicate that human-ungulate conflicts in Europe, as well as in the United States, are likely to increase in parallel with increased expansion in numbers and range of many of these …

A Way Forward For Tax Law And Economics? A Response To Osofsky's "Frictions, Screening, And Tax Law Design", David Gamage

Articles by Maurer Faculty

This Essay responds to Leigh Osofsky's, "Who’s Naughty and Who’s Nice? Frictions, Screening, and Tax Law Design." Osofsky’s analysis suggests that tax rules might be designed so as to take account both of heterogeneity in taxpayers’ tax planning proclivities and of taxpayer characteristics relevant for distribution. By designing tax rules so as to create frictions that differentially impose higher costs on those taxpayers who are more successfully circumventing existing taxes we can perhaps reform our tax system so as to better achieve equitable distribution at lower efficiency costs. This Essay argues that Osofsky's analysis is generally correct and that it …

Finding A Fox: An Evaluation Of Survey Methods To Estimate Abundance Of A Small Desert Carnivore, Steven J. Dempsey, Eric M. Gese, Bryan M. Kluever

United States Department of Agriculture Wildlife Services: Staff Publications

The status of many carnivore species is a growing concern for wildlife agencies, conservation organizations, and the general public. Historically, kit foxes (Vulpes macrotis) were classified as abundant and distributed in the desert and semi-arid regions of southwestern North America, but is now considered rare throughout its range. Survey methods have been evaluated for kit foxes, but often in populations where abundance is high and there is little consensus on which technique is best to monitor abundance. We conducted a 2-year study to evaluate four survey methods (scat deposition surveys, scent station surveys, spotlight survey, and trapping) for …

Report To The Chicago Park District On Conflicts With Ring-Billed Gulls And The 2014 Integrated Ring-Billed Gull Damage Management Project, M. L. Bloomquist, J.W. Hartmann, T.G. Guerrant, S. F. Beckerman, R. M. Engeman

United States Department of Agriculture Wildlife Services: Staff Publications

The large ring-billed gull (Larus delawarensis) population in the City of Chicago has caused various conflicts including general nuisance, property damage, economic losses, and threats to human health and safety. Several studies have shown a relationship between ring-billed gulls and increased levels of fecal indicator bacteria (FIB) such as Escherichia coli (E. coli) in nearshore waters. Results of tests for E. coli have led to the issuance of swim advisories at Chicago beaches.

The objectives of the Chicago Ring-billed Gull Damage Management Project were to (1) reduce the local production of ring-billed gulls, (2) reduce the …

Predicted Wildlife Disease-Related Climate Change Impacts Of Specific Concern To Usda Aphis Wildlife Services, Timothy P. Algeo, Richard B. Chipman, Dennis Slate, Jerome E. Freier, Thomas J. Deliberto

United States Department of Agriculture Wildlife Services: Staff Publications

USDA APHISWildlife Services plans for and responds to a variety of exigencies such as wildlife hazards to aircraft, disease emergence from wildlife translocations, oral rabies vaccine barrier compromises, and extreme weather events. These are often collaborative efforts with state and federal agencies and others. Climate change based in part on fossil fuel use and methane gas emissions has predictable as well as unknown consequences. As a federal leader in wildlife disease research and management, it is incumbent upon Wildlife Services to be current with the scientific literature; assess potential impacts and wildlife disease management intervention needs from predicted climate change …

Economic Impact Of The Potential Spread Of Vampire Bats Into South Texas, Aaron M. Anderson, Steven S. Shwiff, Stephanie A. Shwiff

United States Department of Agriculture Wildlife Services: Staff Publications

Rabies transmitted by the common vampire bat is a major public health concern in subtropical and tropical areas of Latin America, and there is some concern that the species will eventually spread into south Texas. The objective of this study was to estimate the total economic impact of the potential spread of vampire bats into south Texas. Data on livestock populations and values in the relevant counties was combined with expected mortality rates to calculate livestock losses. An IMPLAN model of the regional economy was then used to estimate the secondary impacts experienced by other businesses in the region. These …

Wildlife Damage Management: Changes Over The Last 40 Years And A Look At The Future, Kathleen A. Fagerstone

United States Department of Agriculture Wildlife Services: Staff Publications

Since becoming a wildlife biologist 40 years ago, I have seen many changes. Yet some things have remained the same, like the economic impact of wildlife damage, which was high in 1974 and even higher now. In 2014, the worldwide cost of damage by vertebrate pests to agriculture will exceed $1 billion. The world’s human population has increased at an unprecedented rate, while some wildlife populations have also burgeoned over the past 40 years due to land-use changes and effective management programs. These simultaneous human and wildlife population increases have led to increasing conflicts between humans and wildlife. Nor has …
