The authors note the difficulty they had in obtaining empirical data on medical errors and …

The Spirit Of Nagpra: The Native American Graves Protection And Repatriation Act And The Regulation Of Culturally Unidentifiable Remains, Aaron H. Midler

Chicago-Kent Law Review

In March 2010, the U.S. Department of the Interior issued a final rule regarding the disposition of culturally unidentifiable human remains under the Native American Graves Protection and Repatriation Act (NAGPRA). The rule is controversial, as some commentators argue that the Secretary of the Interior lacks the authority under the statute to regulate these remains. This Note analyzes the legitimacy of the final rule in light of federal administrative law precedent as well as the origin and purpose of NAGPRA. It also discusses two well-known cases arising under the statute and the effect that the final rule will have on …

Preface

Every faculty member at one time or another has known the sinking sensation that he or she is just not reaching students. Since we entered the profession because we love learning and love to facilitate learning, blank stares and dull eyes lead not only to frustration, but also to disappointment. Paraphrasing Lee Shulman, past President of the Carnegie Foundation for the Advancement of Teaching, and a leader in professional education, it is one thing to be competent in subject knowledge and another thing to be competent in subject knowledge pedagogy.

The examples and ideas expressed in these pages come …

Unpredictability In Patent Law And Its Effect On Pharmaceutical Innovation, Christopher M. Holman

Missouri Law Review

Part II of this Article summarizes the current R&D crisis confronting the pharmaceutical industry and the accompanying drop-off in innovative output from this important technological sector. Part III explains Mr. Armitage's "view from industry," which attributes a significant causative effect to unpredictability in the patent system. Part IV provides two Lilly case studies involving generic challenges to two of the company's important drugs, Gemzar and Strattera, in which the company has suffered as a result of this unpredictability. Part V identifies three distinct forms of unpredictability in patent law: unpredictability caused by the proliferation of loosely defined standards rather than …

Forward: Symposium On Evolving The Court Of Appeals For The Federal Circuit And Its Patent Law Jurisprudence, Dennis D. Crouch

Missouri Law Review

As I discuss below, conditions on the ground have changed in the few short months following the Symposium. Congress has now acted, and the Patent Office will soon have additional authority. These changes play directly into the arguments of our Symposium authors and make their results even more important.

Promoting The Progress: Three Decades Of Patent Jurisprudence In The Court Of Appeals For The Federal Circuit, Damon C. Andrews

Missouri Law Review

In the nearly thirty years since the Federal Circuit's first published decision, the court has decided numerous cases that have produced a rich patent jurisprudence. This Article seeks to evaluate that jurisprudence from several perspectives. Part II summarizes the Federal Circuit's patent history in terms of the court's judges, the external factors that have shaped its patent jurisprudence, and the overall success of the court in light of Congress's intent. Part III then evaluates the Federal Circuit's general stance on whether to uphold the PTO's grant or denial of a patent, or a district court's decision to invalidate a patent, …

Part A: The Use Of Nonionic Associative Polymers For The Thickening And Emulsifying Of Personal Care Products/ Part B: The Synthesis Of A Manganese Sod Mimetic For Reactive Coatings, Mallory Lynn Mcmahon

Master's Theses

Part A

The use of nonionic associative thickeners was proposed for personal care applications.  Various limitations of current rheology modifiers used in personal care were discussed.  Nonionic associative polymers were examined as both thickeners and emulsifiers.  The structure/property relationship for nonionic polymers and their ability to thicken and emulsify were fully examined.  Results showed an increase in thickening efficiency for nonionic associative polymers with higher log(P) (partition coefficient) values.  This was due to the formation of smaller aggregates and increased bridging between aggregates.  The connection between oil polarity, log(P) of the associative polymer, and emulsion stability showed no relationship however; …

Reducing High-Risk Drinking In Mandated College Students: Evaluation Of Two Personalized Normative Feedback Interventions, Diana M. Doumas, Camille Workman, Diana Smith, Anabel Navarro

Counselor Education Faculty Publications and Presentations

This study evaluated the efficacy of two brief personalized normative feedback interventions aimed at reducing heavy drinking among mandated college students (N = 135). Students were randomly assigned to one of two conditions: web-based assessment with self-guided personalized normative feedback (SWF) or web-based assessment with counselor-guided personalized normative feedback (CWF). Results indicated students in the CWF condition reported significantly greater reductions in weekly drinking quantity and binge drinking frequency than those in the SWF group at follow-up (M = 8 months). Students in the CWF group also reported significantly greater reductions in estimates of peer drinking from baseline to the …

The Design And Manufacture Of A Microfluidic Reactor For Synthesis Of Cadmium Selenide Quantum Dots Using Silicon And Glass Substrates, Peter Gonsalves

Materials Engineering

A microfluidic reactor for synthesizing cadmium selenide (CdSe) quantum dots (QDs) was synthesized out of silicon and Pyrex glass. Microfabrication techniques were used to etch the channels into the silicon wafer. Holes were wet-drilled into Pyrex glass using a diamond-tip drill bit. The Pyrex wafer was aligned to the etched silicon wafer and both were anodically bonded to complete the microfluidic reactor. Conditions for anodic bonding were created by exposing the stacked substrates to 300V at ~350^oC under 5.46N of force.  Bulk CdSe solution was mixed at room temperature and treated as a single injection. The syringe containing …

Effects Of Species, Water, And Nitrogen On Competition Among Three Prairie Grasses, Jerry L. Weatherford, Randall W. Myster

The Prairie Naturalist

We conducted an experiment to investigate effects of species, water (W), and nitrogen (N) on competition among little bluestem (Schizachyrium scoparium), sideoats grama (Bouteloua curtipendula), and indiangrass (Sorghastrum nutans). All biomass parameters and the root:shoot ratio of little bluestem were reduced by the presence off 1 of 2 other species, and its shoot biomass and total biomass were both increased by addition of N. Root and shoot biomass of sideoats grama were reduced by the presence of indiangrass and its total biomass was reduced by the presence of itself, whereas its shoot biomass was increased by addition of W at …

Assessing The Role Of Conspecific Attraction In Habitat Restoration For Henslow’S Sparrows In Iowa, Jennifer A. Vogel, Rolf R. Koford, David L. Otis

The Prairie Naturalist

The presence of conspecific individuals may provide important cues about habitat quality for territorial songbirds. We tested the ability of a conspecific song playback system to attract Henslow’s sparrows to previously unoccupied restored habitat. We successfully attracted Heslow’s sparrows to 3 of 7 treatment plots using conspecific song playbacks and we found no Henslow’s sparrows in control plots. The addition of social cues using playback systems in restored grassland habitats may aid conservation efforts of Henslow’s sparrows to available habitat.

Notes: River Otters Use Agricultural Field Along The Turtle Riveri In Eastern North Dakota As Crossover And Latrine Area, Maggie D. Triska, Steven C. Loughry, Thomas L. Sergass

The Prairie Naturalist

Recently, the Nearctic river otter (Lontra canadensis) has been re-colonizing portions of eastern North Dakota. The landscape in eastern North Dakota is dominated by agricultural fields and pastures, habitats which have received little research attention related to otter habitat use. During 2008, we searched shorelines to detect otter latrines, which is a common method for determining otter presence. Generally, latrines are locations along bodies of water where otters deposit scats, urine, and glandular secretions for olfactory communication, and groom, wrestle, and play, which may mat vegetation. In the northeastern United States, inland riverine system studies have shown latrines …

Calodium Hepaticum In White-Tailed Jackrabbits In South Dakota, Dustin J. Schaible, Charles D. Dieter, Regg D. Neiger, Michael B. Hildreth

The Prairie Naturalist

White-tailed jackrabbits (Lepus townsendii) are common on the prairie, and an important species in prairie food webs (Lim 1987). Although it has been suggested that jackrabbits have cyclic populations (Donoho 1972, Gross et al. 1974, Anderson and Shumar 1986), there is concern that a general downward trend exists in populations in the Northern Great Plains (Feldhamer et al. 2003). Disease incidence in white-tailed jackrabbits is poorly known (Feldhamer et al. 2003), but may be an important factor in population changes. Tularemia, a disease caused by bacteria (Francisella tularensis), occurs throughout the Northern Hemisphere and can affect many mammals including hares, …

Resource Selection By Elk At Two Spatial Scales In The Black Hills, South Dakota, Mark A. Rumble, R. Scott Gamo

The Prairie Naturalist

Understanding resource selection by elk (Cervus elaphus) at multiple spatial scales may provide information that will help resolve the increasing number of resource conflicts involving elk. We quantified vegetation at 412 sites where the precise location of elk was known by direct observation and 509 random sites in the Black Hills of South Dakota during 1998– 2001. We obtained stand level variables from geographic information system coverages for a 250 m buffer around elk and random sites. We used classification and regression trees to simultaneously evaluate environmental thresholds of resources selected by feeding and bedded elk at the site and …

Multiple Bats Entangled On Cactus, Jon C. Pigage, Richard L. Bunn

The Prairie Naturalist

Accidental deaths of bats by entanglement on plants and barbed wire are common (McNicholl 1988, Norquay et al. 2010). It has been hypothesized these incidents involve miscalculations by bats on how close they fly to plants or barbed wire or when chasing insects highly concentrated around vegetation (Norquay et al. 2010). Once the bats hit the plants or barbed wire, they become entangled and or impaled while struggling to free themselves. The earliest reports involved little brown bats (Myotis lucifugus) and unidentified bats entangled on burdock, Arctium sp. (Lyon 1925, Little 1925). Additional reports of bats becoming entangled in plants …

First Record Of The Least Weasel In The Black Hills Of South Dakota, Tim R. Mullican

The Prairie Naturalist

The least weasel (Mustela nivalis) is a circumboreal species, occurring in North America from Alaska to the Appalachian Mountains (Jones et al. 1983). In the Great Plains, the least weasel recently expanded its range southward through Nebraska (Benedict et al. 2000) and Kansas (Choate et al. 1979, Bailey and Terman 1986) into Oklahoma (Clark and Clark 1988). Also, in recent decades, the least weasel has expanded from eastern and central Nebraska into western Nebraska (Benedict et al. 2000). In South Dakota, least weasels have been previously reported from the eastern 3/4 of the state (Jones et al. 1983, Higgins et …

Phragmites Australis In South Dakota: Historical Distribution And Environment, Carol A. Johnston, Kayla L. Miller

The Prairie Naturalist

Common reed, Phragmites australis, has long been a component of Northern Plains wetlands, but impending invasion by the non-native P. australis haplotype M may displace native haplotypes in the future. To increase understanding of historical Phragmites occurrence, we developed a geographic information system (GIS) protocol to improve the georeferencing of specimens from South Dakota herbaria, and mapped the distribution of Phragmites relative to geology, physiographic regions, and water bodies. There were 91 Phragmites herbarium specimens from South Dakota and adjacent Wyoming. Phragmites collections occurred in nearly all physiographic regions of the state, with concentrations occurring in the Prairie Coteau of …

Crustaceous Zooplankton Transfer Between A Floodplain Wetland And The Missouri River, Shannon J. Fisher

The Prairie Naturalist

Floodplain interactions are a critical riverine ecosystem function, including zooplankton transfer. Floodplain alternations have had an assumed impact on zooplankton productivity. I assessed floodplain wetland and main channel densities of crustaceous zooplankton, alluding to organism transfer in the Missouri River, North Dakota. Significant t-test differences (P < 0.05) were present between backwater and channel habitat zooplankton densities in 83, 75, 83, and 50% of the sample periods for cyclopoid copepods, copepod nauplii, Daphnia spp., and Bosmina spp. respectively, suggesting the presence of uncoupled zooplankton dynamics during portions of each annual cycle. Two relationships with increased flows were found, including a biologically significant decrease (P = 0.09) of backwater copepod nauplii numbers and a significant increase (P = 0.02) in the channel density of Daphnia spp. During the highest flow periods, fewer significant differences in zooplankton densities were present between the backwater and channel habitats, indicating moderate homogenization.

Raster Images In R Graphics, Paul Murrell

Spanish Translation Of Sze-Man Lam's “All About Sexuality: Gender Studies In Pedro Almodovar's Films”, Kurt Ryan Schultheis

World Languages and Cultures

I started researching possible senior project options with the idea in mind of writing a scholarly paper about the films of Pedro Almodóvar. When I looked at all that had been written about him already, I suddenly felt overwhelmed. It seemed that everything that could possibly be said about Almodóvar had already been said, and what could I possibly have to add? Then I found Sze-man Lam's Master of Arts thesis that she wrote in 2004 at the University of Hong Kong. As I read it, I thought, “This is the paper that I wanted to write!” I had all …
