University of Nebraska State Museum: Mammalogy Papers

Jerry Ronald Choate (1943–2009) had just retired as Director of the Sternberg Museum of Natural History and Professor of Biological Sciences, Fort Hays State University, Hays, Kansas, at the time of his death. Jerry served the American Society of Mammalogists in numerous capacities, including Recording Secretary, First Vice President, and most notably as a member and chair of the Board of Trustees.

The hallmark of Jerry’s life was to turn the ordinary into something magnificent. Whether it was his photography that changed an ordinary landscape into a magnificent masterpiece, or his convincing a reluctant graduate student that they could do …

Dna As Patentable Subject Matter And A Narrow Framework For Addressing The Perceived Problems Caused By Gene Patents, Stephen H. Schilling

Duke Law Journal

Concerns about the alleged harmful effects of gene patents— including hindered research and innovation and impeded patient access to high-quality genetic diagnostic tests—have resulted in overreactions from the public and throughout the legal profession. These overreactions are exemplified by Association for Molecular Pathology v. U.S. Patent and Trademark Office, a 2010 case in the Southern District of New York that held that isolated DNA is unpatentable subject matter under 35 U.S.C. § 101. The problem with these responses is that they fail to adequately consider the role that gene patents and patents on similar biomolecules play in facilitating investment in …

Neither Rules Nor Standards, Steven A. Dean

Faculty Scholarship

Specifying the content of a requirement or a prohibition up front-e.g. replacing a "reasonable speed" requirement with a fifty-five miles per hour speed limit-can make life easier for enforcers and citizens alike. Recent efforts to substitute international tax rules for decades-old standards may do just the opposite, jeopardizing the "miracle" that is today's international tax regime. Enhanced information exchange and formulary apportionment will undermine the legitimacy that is essential to the success of any international legal regime. A better solution would overhaul the century-old benefits principle to weave enforcement deep into the fabric of the international tax regime. Only then …

A General Attack Method For Steganography Removal Using Pseudo-Cfa Re-Interpolation, Pradhumna Shrestha, Michael Hempel, Tao Ma, Dongming Peng, Hamid Sharif

Department of Electrical and Computer Engineering: Faculty Publications (to 2015)

Watermarking and steganography are two of the most researched topics in multimedia forensics. However, easy availability of tools and technology has made their misuse a serious concern. To counteract this development some effective tools are necessary to remove malicious steganography. In this work, we introduce a novel watermark attack method which can destroy hidden information embedded in images based on the principle of re-interpolation of Color Filter Array (CFA) artifacts. In digital cameras and scanners, CFA filters are used to acquire low-resolution physical color channel information and produce a high-quality image by subsequent interpolation. We propose to emulate a similar …

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

Water quality monitoring was conducted in two urban watersheds (Colonial Hills and Taylor Park) located in southeast Lincoln, NE over a three year period spanning from October 2008 through September 2011. In-line probes continuously measured for turbidity, conductivity, dissolved oxygen, and water temperature while other water quality constituents were analyzed for discrete water samples collected using grab and automatic sampling techniques. The water quality data was used to calculate event mean concentrations (EMCs) for sixteen storm events sampled over the duration of the project period. Three types of stormwater quality multiple linear regression models were developed for the estimation of …

Development Of A Flow-Based Ultrafast Immunoextraction And Reverse Displacement Immunoassay: Analysis Of Free Drug Fractions, John E. Schiel, Zenghan Tong, Chainarong Sakulthaew, David S. Hage

David Hage Publications

A flow-based method employing a reverse displacement immunoassay was combined with ultrafast immunoextraction and near-infrared fluorescence detection for the analysis of free drug fractions, using phenytoin as a model analyte. Factors considered in the design of this method included the sample application conditions, the design of the immobilized drug analog column, the utilization of antibodies or F_ab fragments as labeled binding agents, and the label application and column regeneration conditions. In the final method, sample injections led to the displacement of labeled binding agents from an immobilized phenytoin analog column. This displacement peak appeared within 20–30 s of sample …

Shaby, Gregor P. Lotz, Yvonne Newhouse, Emily M. Sontag, Alex Osmand, Michelle Gray, Vanitha Thulasiramin, Frederic Saudou, Mark Segal, X William Yang, Eliezer Masliah, Leslie M. Thompson, Paul J. Muchowski, Karl H. Weisgraber, Steven Finkbeiner

Biological Sciences Faculty Research and Publications

Polyglutamine (polyQ) stretches exceeding a threshold length confer a toxic function to proteins that contain them and cause at least nine neurological disorders. The basis for this toxicity threshold is unclear. Although polyQ expansions render proteins prone to aggregate into inclusion bodies, this may be a neuronal coping response to more toxic forms of polyQ. The exact structure of these more toxic forms is unknown. Here we show that the monoclonal antibody 3B5H10 recognizes a species of polyQ protein in situ that strongly predicts neuronal death. The epitope selectively appears among some of the many low-molecular-weight conformational states assumed by …

Investment Treaty Disputes: Ideological Fault Lines And An Evolving Zeitgeist, Locknie Hsu

Research Collection Yong Pung How School Of Law

The zeitgeist of the 21st century in the field of investment treaty arbitrations comprises a rise in the number of such arbitrations and accompanying observations on the unwieldy jurisprudential effects of such a rise. The international investment arbitration community is alive with discussion over these effects, which discussion includes an examination of the value of prior awards as precedents.' The existing regime based on treaty interpretation clearly provides no formal system of precedent and the 'players' (read: arbitrators) change from dispute to dispute as investment arbitration tribunals do not fall within a single, neat judicial hierarchical system. With the number …

To License Or Not To License? A Look At Differing Approaches To Policing The Activities Of Nonlawyer Immigration Service Providers, Careen Shannon

Cardozo Law Review

State (and some local) governments have struggled to find ways to protect immigrants from exploitation by persons falsely holding themselves out as immigration lawyers or claiming expertise as notarios or immigration consultants. Existing legislation ranges from attempts to regulate the activities of nonlawyer immigration service providers (ISPs) by delineating prohibited practices; to requiring ISPs to post a bond or register with the state; to specifically restricting the provision of immigration assistance for compensation by any nonlawyer who is not accredited by the Board of Immigration Appeals to transcription, translation, document procurement and related clerical tasks. A comparative look at the …

Constitutionalizing Immigration Law On Its Own Path, Anne R. Traum

Cardozo Law Review

Courts should insist on heightened procedural protections in immigration adjudication. They should do so under the Fifth Amendment's Due Process Clause rather than by importing Sixth Amendment protections from the criminal context. Traditional judicial oversight and the Due Process Clause provide a better basis than the Sixth Amendment to interpose heightened procedural protections in immigration proceedings, especially those involving removal for a serious criminal conviction. The Supreme Court's immigration jurisprudence in recent years lends support for this approach. The Court has guarded the availability of judicial review of immigration decisions. It has affirmed that courts are the arbiters of constitutional …

Considering The Scope Of Advisal Duties Under Padilla, Lindsay C. Nash

Cardozo Law Review

In Padilla v. Kentucky, the Supreme Court recognized the complexity and severity of immigration penalties triggered by criminal convictions and held that defense attorneys are obligated to advise clients of such consequences. In so doing, the Court explained that specific advice is required when a consequence is clear; at the same time, it acknowledged it is not always possible to ascertain the consequences of a criminal disposition and, when that is the case, counsel's duty is more limited. The Court did not, however, elaborate on the circumstances in which the duty might be limited or explain what advice defense …

When The State Demands Disclosure, Rebecca Aviel

Cardozo Law Review

The obligation to provide certain types of information to government authorities - reporting child abuse, say, or insurance fraud - is proliferating. Are these laws enforceable against lawyers who obtain the sought-after information in the course of representing a client? This Article sets out to answer exactly that question. It begins by explaining why it is wrong to approach the question by balancing the policies that underlie attorney-client confidentiality against those underlying reporting statutes. Such an approach fails to grasp the essential nature of the question, which is one of legislative power and legislative intent. This Article is the first …

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Experiments investigating earthquake response of structures traditionally use conventional wired instruments such as strain gauges, displacement transducers, and accelerometers deployed at key areas of interest throughout structure. for wind turbines the rotor is one of these key areas, but due to rotation it is not possible to use wired instruments without a special slip ring. in a recent experiment conducted using the Network for Earthquake Engineering Simulation (NEES) Large High Performance Shake Table (LHPOST) at the University of California, San Diego (UCSD) the global response of a full scale 65-kW turbine (22 m hub height) was monitored using a novel …

The Role Of Eddies Inside Pores In The Transition From Darcy To Forchheimer Flows, Kuldeep Chaudhary, M. Bayani Cardenas, Wen Deng, Philip C. Bennett

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

We studied the role of intra-pore eddies, from viscous to inertial flows, in modifying continuum-scale flow inside pores. Flow regimes spanning Reynolds Number Re ∼ 0 to 1350 are divided into three zones - one zone follows Darcy flow, and the other two zones describe non-Darcy or Forchheimer flow. During viscous flows, i.e., Re < 1, stationary eddies occupy about 1/5 of the pore volume. Eddies grow when Re > 1, and their growth leads to the deviation from Darcy's law and the emergence of Forchheimer flow manifested as a characteristic reduction in the apparent hydraulic conductivity K_a. The reduction in K_a is due to the narrowing of the flow channel which is …

Revising An Extension Education Website For Limited Resource Audiences Using Social Marketing Theory, Sarah L. Francis, Peggy Martin, Kristin Taylor

Journal of Extension

Spend Smart Eat Smart (SSES), a unique website combining nutrition and food buying education for limited resource audiences (LRAs), was revised using social marketing theory to make it more appealing and relevant to LRAs (25-40 years). Focus groups and surveys identified the needs and preferences of LRAs. Needs were cooking, basic health, and budget-friendly nutrition ideas. Preferences were limited text, more videos, graphics, and color. Usability testing of the revised site indicated users perceived the information valuable and the design appealing. By incorporating the needs and preferences of LRAs, SSES is now perceived as appealing as well as relevant.

An Assessment Of Current Feeding Practices In Louisiana Dairy Farms, C Leonardi, Vr Moreira, Rd Bardwell, Me Mccormick, M. Autin, B. Perez, M. C. Martinez

Journal of Extension

A survey of producers was conducted to determine feeding practices on Louisiana dairy farms. A 38.5% response rate among dairy farmers was obtained. Declared herd size averaged 108 Holstein milking cows producing 15,613 lbs/cow/year. Most producers relied on pastures as primary forage source for the cows. Pastures were supplemented with concentrates offered twice daily. Most farmers formulated rations and reported knowing dietary protein, but less than 20% of the respondents acknowledged dietary P content. Producers and company nutritionists should be targeted by Extension programs intended to inform about P feeding recommendations and environmental effects of excess P.

More high quality child care is needed in the United States. This article evaluates the Better Kid Care (BKC) program produced by Pennsylvania State University Extension. Child care staff in Wisconsin were interviewed about changes they had made in their early childhood programs following participation in the BKC program. Findings show that 2 months post-program, most participants could name specific skills or knowledge they learned and improvements they made in their early childhood programs as a result of BKC. The BKC program improves child care quality, and increasing program participation is recommended.

Application Of Threshold Concepts To Improve A Design-Focused Course In Transportation Engineering, Dan Cernusca, Ghulam Bham

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Design is an integral part of engineering courses. to address its associated problems, however, is a challenging task in instruction because of design's open-endedness and complexity. in this study, two theoretical models were implemented in an introductory transportation engineering course to address the challenges associated with design of a highway. First, the theoretical framework proposed by the threshold concepts model was used to identify a candidate concept for the instructional redesign process. Two major characteristics of threshold concepts, integrativity and transformativity, were used to identify horizontal alignment as a candidate concept for the highway design process. Second, concept mapping was …

Towards Failure Free Design: An Analysis Of Risk Mitigation Communication, Daniel Krus, Katie Grantham

Engineering Management and Systems Engineering Faculty Research & Creative Works

In order to ensure that risk mitigation strategies are properly communicated to and understood by those who would use them in future designs, a common language of risk mitigation should exist. This paper focuses on a set of elements for describing risk mitigation strategies based on a linguistic analysis of the information such strategies must communicate to the design team. Sample strategies are then decomposed into these attributes and evaluated using the Gricean cooperation principle, relevance theory, and functional analysis theories from the pragmatics sub-field of linguistics. using the deficiencies found from this analysis, a format for risk mitigation strategies …

Stochastic Policy Search For Variance-Penalized Semi-Markov Control, Abhijit Gosavi, Mandar Purohit

Engineering Management and Systems Engineering Faculty Research & Creative Works

The variance-penalized metric in Markov decision processes (MDPs) seeks to maximize the average reward minus a scalar time the variance of rewards. in this paper, our goal is to study the same metric in the context of the semi-Markov decision process (SMDP). in the SMDP, unlike the MDP, the time spent in each transition is not identical and may in fact be a random variable. We first develop an expression for the variance of rewards in the SMDPs, and then formulate the VP-SMDP. Our interest here is in solving the problem without generating the underlying transition probabilities of the Markov …
