Empowering Or Compelling Reluctant Participators Using Audience Response Systems, Charles R. Graham, Tonya R. Tripp, Larry Seawright, George L. Joeckel Iii

Faculty Publications

This article investigates the impact of an audience response system (ARS) on student engagement in undergraduate university courses. A survey was administered to students in a dozen courses piloting the ARS system. On 13 out of 14 measures the majority of students thought the system was helpful. Overall, students were more positive about the use of the ARS in courses that used the tool for formative feedback (empowering) rather than for grading or attendance purposes (compelling). The authors discuss the positive impact of the ARS on the engagement of ‘reluctant participators’ or students who reported that they are least likely …

Bite Mark Analysis, Paul C. Giannelli

Faculty Publications

Courts have admitted bite mark comparison evidence in homicide, rape, and child abuse cases. By the 1980s, the technique had gained widespread judicial acceptance. Hundreds of cases have admitted this type of evidence, and no reported case has rejected it. Moreover, some courts speak of bite mark comparison as a "science." Indeed, its acceptance is so well-established that several courts have taken judicial notice of its reliability, implying that the validity of the technique is not subject to reasonable dispute.

Yet, the scientific foundations for bite mark comparisons has never been demonstrated. Such basic issues as the uniqueness of the …

Spatial Ecology Of The Coachwhip, Masticophis Flagellum (Squamata: Colubridae), In Eastern Texas, Richard W. Johnson, Robert R. Fleet, Michael B. Keck, D. Craig Rudolph

Faculty Publications

We radio-tracked nine Masticophis flagellum (Coachwhips) to determine home range, habitat use, and movements in eastern Texas from April to October 2000. Home ranges of Coachwhips contained more oak savanna macrohabitat than early-successional pine plantation or forested seep, based on the availability of these three macrohabitats in the study area. Likewise, within their individual home ranges, Coachwhips used oak savanna more than the other two macrohabitats, based on availability. An analysis of microhabitat use revealed that, relative to random sites within their home range, Coachwhips were found at sites with fewer pine trees and more herbaceous vegetation taller than 30 …

A Concise History Of International Criminal Law, Beth Van Schaack, Ron Slye

Faculty Publications

This work is an introductory chapter for a forthcoming book on Understanding International Criminal Law to be published by Aspen Publishers as part of Aspen's Essentials series. This chapter presents a succinct history of international criminal law (ICL), drawing upon major developments in the law of armed conflict, international human rights law, and the criminal prohibitions against piracy and the slave trade. The chapter interweaves the history of substantive norms with that of evolving principles of domestic and international jurisdiction, as these narratives are virtually inseparable in ICL. Additional chapters in the text will address the sources of ICL, the …

Effect Of Water On The Electrochemical Oxidation Of Gas-Phase So2 In A Pem Electrolyzer For H2 Production, John Staser, Ramaraja P. Ramasamy, Premkumar Sivasubramanian, John W. Weidner

Faculty Publications

Water plays a critical role in producing hydrogen from the electrochemical oxidation of SO2 in a proton exchange membrane (PEM) electrolyzer. Not only is water needed to keep the membrane hydrated, but it is also a reactant. One way to supply water is to dissolve SO2 in sulfuric acid and feed that liquid to the anode, but this process results in significant diffusion resistance for the SO2. Alternatively, we have developed a process where SO2 is fed as a gas to the anode compartment and reacts with water crossing the membrane to produce sulfuric acid. There was concern that the …

Damages In Tort Litigation: Thoughts On Race And Remedies, 1865-2007, Jennifer Wriggins

Faculty Publications

The relationship between remedies and race in U.S. tort law merits attention. This essay first challenges the boundary between civil rights and tort remedies by highlighting a stunning but previously overlooked 1959 Fifth Circuit case where an individual tort remedy served as a significant civil rights remedy in the integration of public transportation throughout the South. Second, the essay focuses on the relationship between race and damages from 1865 to the present. It argues that the torts system provided access to indigent plaintiffs of all races during periods when poor people were otherwise denied legal representation in every other context. …

Praying, Playing, And Successful Families: An Examination Of Family Religiosity, Family Leisure, And Family Functioning, Sarah Taylor Agate, Ramon B. Zabriskie, Dennis L. Eggett

Faculty Publications

The purpose of this study was to examine the relationship between family religiosity, family leisure, and family functioning. The sample consisted of 121 parents and 99 youth from various religious groups. Results indicated a positive relationship between family religiosity and family leisure. Both family religiosity and family leisure had a significant relationship with family functioning in this sample. Data collected from both parents and youth provided insight into the influence of family religiosity and family leisure on family functioning. Family religiosity was the strongest predictor of family functioning for parents. For youth, both family leisure and family religiosity were significant …

Disability Human Rights, Michael Ashley Stein

Faculty Publications

Responding to the absence of an international treaty expressly protecting people with disabilities, the United Nations General Assembly will soon adopt a disability-based human rights convention. This Article examines the theoretical implications of adding disability to the existing canon of human rights, both for individuals with disabilities and for other under-protected people. It develops a "disability human rights paradigm" by combining components of the social model of disability, the human right to development, and Martha Nussbaum's version of the capabilities approach, but filters them through a disability rights perspective to preserve that which provides for individual flourishing and modifying that …

Biogeography And The Cambrian Radiation Of Arachnomorph Arthropods, Jonathan R. Hendricks, Bruce S. Lieberman

Faculty Publications

Biogeographic patterns in primarily Cambrian arachnomorph taxa are investigated using a recently constructed phylogenetic hypothesis in order to explore the biogeographic context of the Cambrian radiation. A modified version of Brooks Parsimony Analysis is employed to elucidate patterns of vicariance and geodispersal in taxa from six regions (Laurentia, Baltica, Siberia, Australia, Africa and China). Well resolved vicariance and geodispersal trees are very similar and reconstruct Laurentia and China as sister areas. This close area relationship between Laurentia and China provides extensive evidence for congruent vicariance and range expansion in Cambrian arachnomorphs, while data from trilobites do not show this pattern. …

Interdisciplinary Research At The University Of Illinois At Chicago: A Campus-Wide Survey Of Climate, Obstacles And Opportunities, Dennis Rosenbaum, Amie Schuck, Mark Mattaini, Ericka Adams

Faculty Publications

In recent years, the administration, faculty and research professionals at the University of Illinois at Chicago have shown considerable interest in facilitating interdisciplinary research on campus. Beginning in 2006, the Office of the Provost and the Office of the Vice Chancellor for Research provided seed funding for the creation of several interdisciplinary research (IDR) centers on campus to encourage interdisciplinary and transdisciplinary scholarship and education. This study is a product of one of those centers – the UIC Interdisciplinary Center for Research on Violence. The study was undertaken with three primary objectives: (1) to assess the IDR climate and level …

Utilizing Focus Groups To Evaluate An Information Literacy Program In A General Biology Course, Betsy S. Hopkins

Faculty Publications

The Harold B. Lee Library at Brigham Young University (BYU) recently implemented a number of information literacy strategies to help students in Biology 100, a large general education class, find resources for their term assignment. The library's services for Biology 100 students were evaluated using focus groups composed of both teaching assistants and students. This paper will describe the class and the assignment, discuss the impact the class had on library staff, detail the efforts of the staff to meet the needs of Biology 100 students, and present results of focus groups used to evaluate the library's outreach and teaching …

Attributes Of Meaningful Learning Experiences In An Outdoor Education Program, Stacy T. Taniguchi, Patti A. Freeman, A. Legrand Richards

Faculty Publications

This phenomenological study sought to identify the attributes of meaningful learning experiences as found in an outdoor education program. Thirteen students in the Wilderness Writing Program at Brigham Young University were the sample of this study. Their participation in outdoor recreational activities and their reflections about their experiences were analyzed. Through written journal entries, group discussions, observations, and writing assignments, a qualitative analysis identified attributes that occurred in their meaningful learning experiences. Meaningful learning was defined as a realization of a person's weaknesses, strengths, and potentials. This realization came through experiences with attributes of a degree of perceived risk, which …

Missing The Link: The Importance Of Keeping Ecosystems Intact And What The Endangered Species Act Suggests We Do About It, Kalyani Robbins

Faculty Publications

The Endangered Species Act was created in response to a rapid decline in species biodiversity. Although Congress chose direct protection of individual species as its tool, protecting ecosystems (a necessary component of biodiversity) was clearly one of the goals for which that tool was to be used. A species can be abundant in some areas and declining in others, such that protecting the entire species does not make sense. Congress dealt with this issue by amending the Endangered Species Act in 1978 to allow for protection of “distinct population segments,” thereby allowing the population in decline to be protected in …

Multiple Mixed-Type Attractors In A Competition Model, J. M. Cushing, Shandelle M. Henson, Chantel C. Blackburn

Faculty Publications

We show that a discrete-time, two-species competition model with Ricker (exponential) nonlinearities can exhibit multiple mixed-type attractors. By this is meant dynamic scenarios in which there are simultaneously present both coexistence attractors (in which both species are present) and exclusion attractors (in which one species is absent). Recent studies have investigated the inclusion of life-cycle stages in competition models as a casual mechanism for the existence of these kinds of multiple attractors. In this paper we investigate the role of nonlinearities in competition models without life-cycle stages. © 2007 Taylor & Francis Group, LLC.

Are Botanists Becoming The Dinosaurs Of Biology In The 21st Century?, Dennis W. Woodland

Faculty Publications

The number of botany students, botany classes, botany departments in universities and botanists attending conventions has been declining over many years in North America. This is part of a general trend throughout the field of organismal biology, not just botany. The history leading up to the situation today in North America, is discussed and reasons are given for this trend over the last century of time. Seven ways to keep botany a viable occupation are discussed otherwise botany, in the 21st century, may go the way of the dinosaur. © 2007.

"If You Want Me To Treat You Like An Adult, Start Acting Like One!" Comparing The Criteria That Emerging Adults And Their Parents Have For Adulthood, Larry J. Nelson, Laura M. Padilla-Walker, Jason S. Carroll, Stephanie D. Madsen, Carolyn Mcnamara Barry, Sarah Badger

Faculty Publications

The purpose of this study was (a) to identify the criteria parents of emerging adults consider necessary and important for their children to achieve adulthood, (b) to compare parents' criteria for adulthood with the criteria espoused by emerging adults, and (c) to examine how these criteria might differ on the basis of gender and the parent and gender of the child. Participants included 392 unmarried college students, ages 18–25, and at least 1 of their parents (271 fathers, 391 mothers). Results revealed that (a) as did their children, most parents did not yet view their children as adults, (b) there …

Using Live Modeling To Train Preservice Teachers To Integrate Technology Into Their Teaching, Charles R. Graham, Richard E. West

Faculty Publications

One method underutilized in training teachers to use technology is to use live modeling sessions. This study qualitatively investigates how the use of modeling sessions impacted students. In this study we found that modeling was perceived by most students to be effective at teaching technology skills and ideas for integrating technology as teachers. However, we identified several breakdowns in the ability of students to transfer their understanding of technology integration to their own situations. We explain this difficulty of transfer of learning and describe five situations when these breakdowns were likely to occur. Implications include the benefits of using live …

Lip Kinematics In Spasmodic Dysphonia Before And After Treatment With Botulinum Toxin, Christopher Dromey, Aubrey Reese, Susan Howey

Faculty Publications

In order to learn about articulatory behavior in adductor spasmodic dysphonia (SD), the lip movements of seven individuals with SD and three control speakers were recorded with strain gauges as they repeated 'Buy Bobby a puppy' in voiced and whispered conditions. Results included weaker bilabial coordination, qualitative differences in the shape of lip movement profiles, and an increased number of lip velocity peaks in the speakers with SD. These participants received percutaneous botulinum toxin injection to the thyroarytenoid muscle, and were then recorded again. The pre- vs. post-treatment data revealed that improved vocal activity was associated with fewer articulatory disturbances. …

Pharmaceutical Compounds In Wastewater: Wetland Treatment As A Potential Solution, John R. White, Marco A. Belmont, Chris D. Metcalfe

Faculty Publications

Pharmaceutical compounds are being released into the aquatic environment through wastewater discharge around the globe. While there is limited removal of these compounds within wastewater treatment plants, wetland treatment might prove to be an effective means to reduce the discharge of the compounds into the environment. Wetlands can promote removal of these pharmaceutical compounds through a number of mechanisms including photolysis, plant uptake, microbial degradation, and sorption to the soil. We review relevant laboratory research on these various mechanisms and provide data on the few studies that have examined wetland removal. There is a need to document the degree to …

Epinecrophylla, A New Genus Of Antwrens (Aves: Passeriformes: Thamnophilidae), Morton L. Isler, Daniela Rodrigues Lacerda, Phyllis R. Isler, Shannon J. Hackett, Kenneth V. Rosenberg, Robb T. Brumfield

Faculty Publications

We offer a new generic name for the stipple-throated assemblage of antwrens (Thamnophilidae) currently placed in the genus Myrmotherula. Molecular studies demonstrated that Myrmotherula is polyphyletic, with the stippled-throated group forming a clade that is not sister to any other currently recognized Myrmotherula species. The stipple-throated assemblage is distinguished morphologically by at least one sex having a black throat stippled white or buffy white combined with a comparatively long, unmarked tail, although three populations considered subspecies have lost one of these characters. The distinct evolution of this assemblage is supported by diagnostic behavioral characters derived from foraging behaviors, vocal repertoires, …

Mammalian antimicrobial peptides (AMPs) are effectors of the innate immune response. A multitude of signals coming from pathways of mammalian pathogen/pattern recognition receptors and other proteins affect the expression of AMP-coding genes (AMPcgs). For many AMPcgs the promoter elements and transcription factors that control their tissue cell-specific expression have yet to be fully identified and characterized. Results- Based upon the RIKEN full-length cDNA and public sequence data derived from human, mouse and rat, we identified 178 candidate AMP transcripts derived from 61 genes belonging to 29 AMP families. However, only for 31 mouse genes belonging to 22 AMP families we …

Geological And Oceanographic Perspectives On Event Bed Formation During Hurricane Katrina, T. R. Keen, Y. Furukawa, S. J. Bentley, R. L. Slingerland, W. J. Teague, J. D. Dykes, C. D. Rowley

Faculty Publications

Storm deposits in ancient shelf sediments typically form thick sequences of interbedded sand and mud deposited during shoreline regression, whereas modern shelf sediments are generally thin veneers deposited during shoreline transgression. In this paper we present a preliminary comparison between ancient and modern storm beds deposited in these disparate contexts. Hurricane Katrina deposited a storm bed on the Louisiana shelf with a maximum observed thickness of 0.58 m, which thinned to approximately 0.1 m at 200 km west of landfall. This thickness is similar to event beds observed in both ancient and modern sediments. Using data for tropical cyclone landfalls …

Performance Of The Nzi And Other Traps For Biting Flies In North America, S. Mihok, D. A. Carlson, E. S. Krafsur, L. D. Foil

Faculty Publications

The performance of Nzi traps for tabanids (Tabanus similis Macquart, T. quinquevittatus Wiedemann, Chrysops aberrans Philip, C. univittatus Macquart, C. cincticornis Walker, Hybomitra lasiophthalma (Macquart)), stable flies (Stomoxys calcitrans Linnaeus) (Diptera: Muscidae) and mosquitoes (Aedes) (Diptera: Culicidae) was investigated at various sites in Canada (Ontario, Alberta) and USA (Iowa, Florida, Louisiana). Traps made from selected fabrics, insect nettings and hand-dyed blue cotton were compared to the African design to provide practical recommendations for temperate environments. Comparisons of substituted materials showed that trap performance was optimal only when traps were made from appropriate fabrics in the colours produced by either copper …

Amyloid-Β-Induced Pathological Behaviors Are Suppressed By Ginkgo Biloba Extract Egb 761 And Ginkgolides In Transgenic Caenorhabditis Elegans, Yanjue Wu, Zhixin Wu, Peter Butko, Yves Christen, Mary P. Lambert, William L. Klein, Christopher D. Link, Yuan Luo

Faculty Publications

Amyloid-β (Aβ) toxicity has been postulated to initiate synaptic loss and subsequent neuronal degeneration seen in Alzheimer's disease (AD). We previously demonstrated that the standardized Ginkgo biloba extract EGb 761, commonly used to enhance memory and by AD patients for dementia, inhibits Aβ-induced apoptosis in neuroblastoma cells. In this study, we use EGb 761 and its single constituents to associate Aβ species with Aβ-induced pathological behaviors in a model organism, Caenorhabditis elegans. We report that EGb 761 and one of its components, ginkgolide A, alleviates Aβ-induced pathological behaviors, including paralysis, and reduces chemotaxis behavior and 5-HT hypersensitivity in a transgenic …
