A Preliminary Examination Of The Cost Savings And Learning Impacts Of Using Open Textbooks In High School Science Classes, David Wiley, John Levi Hilton Iii, Shelley Ellington, Tiffany Hall

Entrepreneurship Faculty Research

Proponents of open educational resources claim that significant cost savings are possible when open textbooks displace traditional textbooks in the classroom. Over a period of two years, we worked with 20 middle and high school science teachers (collectively teaching approximately 3,900 students) who adopted open textbooks to understand the process and determine the overall cost of such an adoption. The teachers deployed open textbooks in multiple ways. Some of these methods cost more than traditional textbooks; however, we did identify and implement a successful model of open textbook adoption that reduces costs by over 50% compared to the cost of …

Discrepant Visual Speech Faciliates Covert Selective Listening In "Cocktail Party" Conditions, Jason A. Williams

Psychology and Child Development

The presence of congruent visual speech information facilitates the identification of auditory speech, while the addition of incongruent visual speech information often impairs accuracy. This latter arrangement occurs naturally when one is being directly addressed in conversation but listens to a different speaker. Under these conditions, performance may diminish since: (a) one is bereft of the facilitative effects of the corresponding lip motion and (b) one becomes subject to visual distortion by incongruent visual speech; by contrast, speech intelligibility may be improved due to (c) bimodal localization of the central unattended stimulus. Participants were exposed to centrally presented visual and …

Proliferation Security Initiative: Origins And Evolution, Susan J, Koch

WMD Occasional Papers

On December 9, 2002, the United States and Spanish navies cooperated to interdict a North Korean vessel, the So San, in the Arabian Sea.¹ The operation initially appeared to be an unqualified success, a textbook example of interdiction to prevent proliferation of weapons of mass destruction (WMD), related materials, or delivery systems. According to press reports, the United States began tracking the vessel when it first left North Korea, believing that it was carrying a cargo related to Scud ballistic missiles. The So San flew no flag, making it a stateless vessel under international law, subject to interception …

Policy On Habitat Enhancement Structures In Western Australia, Department Of Fisheries Western Australia.

Habitat enhancement structures range widely in design. They generally aim to enhance fish habitat by providing a structure for fish and other aquatic life to colonise and potentially lead to an increase in their biological production.

The primary function of an artificial reef is to provide additional structure and habitat to support an increased production of fish ad other aquatic organisms.

Foodborne Illness Outbreak Response: A Snapshot Of Ohio, Calen Wherry

Master of Public Health Program Student Publications

Biosurveillance is one of the primary roles of local Public health offices. As the all-hazards (biological, chemical, and radiation emergencies) approach adds to the responsibilities already performed in foodborne illness outbreak response, it is crucial to assess the capabilities and robustness of the local public health Foodborne Illness (FBI) response. By surveying the most populated counties in Ohio with a checklist based on the 2009 Council for Improvement of Foodborne Outbreak Response (CIFOR) guidelines, it was possible to obtain a snapshot of the current outbreak response capabilities. Though only one county reported 100% compliance with the checklist, the overall average …

Fostering And Foreclosing Student Learning Potential: Portraits Of Performativity, Emotion, And Relationality In The Classroom, Jeanne Marie Jacobs

Electronic Theses and Dissertations

This dissertation endeavors to build a much-needed bridge between the fields of communication and education. Using critical pedagogy and critical communication pedagogy as theoretical frameworks, this project advances an understanding of classroom communication as constitutive of power relations, and teachers and students as agents who can work together to foster learning potential and social justice. I look to interdisciplinary scholarship on affect to craft a nuanced conceptual framework of the connection between communication and emotion, and how they create learning opportunities for some students and construct barriers to learning for others. Through ethnographic fieldwork at an urban magnet school, I …

Synthetic Biology: Does Re-Writing Nature Require Re-Writing Regulation?, Jordan Paradise, Ethan Fitzpatrick

Dickinson Law Review (1908-2003)

Technological advancements in the life sciences are continually pressing forward despite frequent and vocal resistance. Examples of such advancements include reproductive technologies, genetics, stem cell research, nanotechnology, and now synthetic biology. In May 2010, the J. Craig Venter Institute, a multidisciplinary scientific organization led by one of the first scientists to sequence the human genome, announced in the journal Science the creation of the first synthetic cell-a manmade, single-celled organism with the ability to self-replicate. While hailed as a monumental step forward for science, the response from opponents was swift: stop the science from going forward, keep the products off …

An Emerging Hispanic Serving Institution Looks Toward The Future: A Case Study On A Collaborative, Community-Based Systemic Change Effort At An Urban Land-Grant College, Eric Dunker

Electronic Theses and Dissertations

Many higher education organizations face the issue of structural isolation (Ruben, 2004) based on a lack of integration and functional coordination between faculty, staff, and students. Community-based research (CBR) offers higher education a more collaborative, wider reaching avenue of organizing a variety of stakeholders around social change. The CBR model is an atypical change model due to its interdisciplinary, participatory, and collaborative structure that values multiple sources of knowledge and focuses on social justice action. As opposed to serving as the 'experts' who were performing research on a community of people, academics and community members who utilize CBR focus on …

Harvesting The "Forbidden Fruit" Of Biotechnology Research: Genetic Engineering, International Law And The Patentability Of Higher Life Forms In Canada, Eugene C. Lim

Canadian Journal of Law and Technology

As the frontiers of science are constantly redefined by the emergence of new technology, patent law often has to struggle to keep pace with the changing conception of what constitutes a protectable “invention”. A key challenge facing patent law in the age of biotechnology lies in ascertaining the extent to which genetically engineered life forms should be protected. A major concern relates to whether such life forms should be excluded from patentability on grounds of ordre public, ethics and morality.

This article critically explores the extent to which patent law in Canada protects this “forbidden fruit” of biotechnological innovation, and …

Dissection Of The Role Of The Stable Signal Peptide Of The Arenavirus Envelope Glycoprotein In Membrane Fusion, Emily L. Messina, Joanne York, Jack H. Nunberg

Biological Sciences Faculty Publications

The arenavirus envelope glycoprotein (GPC) retains a stable signal peptide (SSP) as an essential subunit in the mature complex. The 58-amino-acid residue SSP comprises two membrane-spanning hydrophobic regions separated by a short ectodomain loop that interacts with the G2 fusion subunit to promote pH-dependent membrane fusion. Small-molecule compounds that target this unique SSP-G2 interaction prevent arenavirus entry and infection. The interaction between SSP and G2 is sensitive to the phylogenetic distance between New World (Junin) and Old World (Lassa) arenaviruses. For example, heterotypic GPC complexes are unable to support virion entry. In this report, we demonstrate that the hybrid GPC …

Exposure To Host Ligands Correlates With Colocalization Of Gal/Galnac Lectin Subunits In Lipid Rafts And Phosphatidylinositol (4,5)-Bisphosphate Signaling In Entamoeba Histolytica, Amanda M. Goldston, Rhonda R. Powell, Amrita B. Koushik, Lesly A. Temesvari

Publications

Entamoeba histolytica is an intestinal parasite that causes dysentery and liver abscess. Parasite cell surface receptors, such as the Gal/GalNAc lectin, facilitate attachment to host cells and extracellular matrix. The Gal/GalNAc lectin binds to galactose or N-acetylgalactosamine residues on host components and is composed of heavy (Hgl), intermediate (Igl), and light (Lgl) subunits. Although Igl is constitutively localized to lipid rafts (cholesterol-rich membrane domains), Hgl and Lgl transiently associate with this compartment in a cholesterol-dependent fashion. In this study, trophozoites were exposed to biologically relevant ligands to determine if ligand binding influences the submembrane distribution of the subunits. Exposure …

The Characterization And Comparison Of Biochar Produced From A Decentralized Reactor Using Forced Air And Natural Draft Pyrolysis, Leah Herbert, Ian Hosek, Rishi Kripalani

Materials Engineering

The soil additive properties of biochar have proven both effective and globally beneficial, but depend heavily on feedstock used and process conditions. This study characterizes how forced and natural draft air flows affect the biochar’s soil amendment potential. Biochars manufactured from two pine species of feedstock, in timber and pellet form, were compared against a designer biochar. The designer biochar held the lowest C:N ratio (57.43), followed by the natural draft pellets (199.5), forced air timber (282.5), forced air pellets (422.7), and natural draft timber (503.7). The designer char had the largest cation exchange capacity at 138.5 cmolc/kg; the decentralized …

Artificial Alveolar-Capillary Membrane On A Microchip, Keith Male

Materials Engineering

A microfluidic device was synthesized out of polydimethyl siloxane (PDMS) to simulate the structure of the alveolar-capillary interface of the human lung. Soft lithography techniques were used to build a mold structure out of SU-8 epoxy at heights ranging from 30µm to 110 µm on a silicon substrate, with the 70 µm structure working the best. A mixture of 10:1 Sylgard 184 elastomer was then cast using the mold, and cured at a temperature of 80^oC. For the porous membrane, the PDMS was spun on at 6000rpm for 30 seconds using a spin coater to produce a membrane …

The Mitigation Of Eutrophication Using Microporous Polymer Membranes To Control Algae Growth, Christopher R. Riley

Materials Engineering

A system was designed to mitigate the accelerated process of anthropogenic eutrophication. This system aimed to contain Chlorella Vulgaris microalgae cells within an enclosed polymer membrane pouch while allowing for water and nutrients to diffuse through the pouch. As a test model, a 10 gallon aquarium was partitioned into three sections using polycarbonate membranes with 1 micron pore diameters. Each section was then gradually filled with a deionized water and Bristol solution recommended for microalgae growth. Phosphate and nitrate were added to Section A of the aquarium and allowed to diffuse throughout the tank. A water pump was used to …
