To See Daydreams: The Glass Utopia Of Paul Scheerbart And Bruno Taut, Ufuk Ersoy Jan 2011

To See Daydreams: The Glass Utopia Of Paul Scheerbart And Bruno Taut, Ufuk Ersoy

Publications

In 1914, the passionate young architect Bruno Taut (1880-1938) and the bohemian poet Paul Scheerbart (1863-1915) drew a parallel between the two imaginative disciplines of building and narrative and committed themselves to a shared vision of Utopia. Both sought to represent an archetype of “glass architecture”; one by narrating, the other by building. Highly critical of existing architecture and social conditions, they were in search of an inspiring alternative, as were many of their more progressive contemporaries. Yet, what made Taut and Scheerbart’s shared approach more sophisticated than that of their contemporaries also left it open to criticism. In particular, …

A Possible Pathway For High School Science In A Stem World, Cary Sneider Jan 2011

A Possible Pathway For High School Science In A Stem World, Cary Sneider

Publications

Today‘s high school science teachers find themselves in a period of transition. For the past decade there have been calls for replacing a narrow focus on science education—the traditional courses in physics, chemistry, biology, and Earth and space science—with a broader curriculum on STEM (that is, the four allied fields of science, technology, engineering, and mathematics). However, at present there are no guidelines on what that broader curriculum should include or how it should be designed, and the gulf that has separated science and mathematics seems as wide as ever, despite decades of efforts to bridge the two disciplines.

Mapping Engineering Concepts For Secondary Level Education, Jenny L. Daugherty Jan 2011

Mapping Engineering Concepts For Secondary Level Education, Jenny L. Daugherty

Publications

Much of the national attention on science, technology, engineering, and mathematics (STEM) education tends to concentrate on science and mathematics, with its emphasis on standardized test scores. However as the National Academy of Engineering Committee on K-12 Engineering Education stressed, engineering can contribute to the development of an effective and interconnected STEM education system (Katehi, Pearson, & Feder, 2009). In addition, engineering can provide authentic learning contexts for science, technology, and mathematics. Numerous K-12 engineering initiatives have emerged across the U.S. developing curriculum and conducting teacher professional development (Brophy, Klein, Portsmore, & Rogers, 2008). The focus of pre-college engineering education …

Design Problems For Secondary Students, David H. Jonassen Jan 2011

Design Problems For Secondary Students, David H. Jonassen

Publications

Are there different kinds of design problems? According to Brown and Chandrasekaran (1989), Class 1 design problems are open-ended, non-routine creative activities where the goals are ill-structured, and there is no effective design plan specifying the sequence of actions to take in producing a design model. Class 2 problems use existing, well-developed design and decomposition plans (e.g. designing a new automobile). Class 3 designs are routine where design and decomposition plans are known as well as customary actions taken to deal with failures (e.g., writing a computer program). Jonassen (2011) argued that problems vary in terms of structuredness, complexity, and …

Building A Framework For Engineering Design Experiences In Stem: A Synthesis, Cameron D. Denson Jan 2011

Building A Framework For Engineering Design Experiences In Stem: A Synthesis, Cameron D. Denson

Publications

Since the inception of the National Center for Engineering and Technology Education in 2004, educators and researchers have struggled to identify the necessary components of a “good” engineering design challenge for high school students. In reading and analyzing the position papers on engineering design many themes emerged that may begin to form a narrative for engineering design in a high school setting. Before educators can provide a framework for engineering design in STEM courses, four questions need to be answered: (a) To what degree should engineering design challenges be open-ended or well-structured? (b) What are the relationships between engineering design …

Femoral Loading Mechanics In The Virginia Opossum (Didelphis Virginiana): Torsion And Mediolateral Bending In Mammalian Locomotion, W. Casey Gosnell, Michael T. Butcher, Takashi Maie, Richard W. Blob Jan 2011

Femoral Loading Mechanics In The Virginia Opossum (Didelphis Virginiana): Torsion And Mediolateral Bending In Mammalian Locomotion, W. Casey Gosnell, Michael T. Butcher, Takashi Maie, Richard W. Blob

Publications

Studies of limb bone loading in terrestrial mammals have typically found anteroposterior bending to be the primary loading regime, with torsion contributing minimally. However, previous studies have focused on large, cursorial eutherian species in which the limbs are held essentially upright. Recent in vivo strain data from the Virginia opossum (Didelphis virginiana), a marsupial that uses a crouched rather than an upright limb posture, have indicated that its femur experiences appreciable torsion during locomotion as well as strong mediolateral bending. The elevated femoral torsion and strong mediolateral bending observed in D. virginiana might result from external forces such as a …

Biodiesel Production From Crude Cottonseed Oil: An Optimization Process Using Response Surface Methodology, Xiaohu Fan, Xi Wang, Feng Chen Jan 2011

Biodiesel Production From Crude Cottonseed Oil: An Optimization Process Using Response Surface Methodology, Xiaohu Fan, Xi Wang, Feng Chen

Publications

Biodiesel, known as fatty acid methyl ester (FAME), was produced from crude cottonseed oil (triglycerides) by transesterification with methanol in the presence of sodium hydroxide. This process was optimized by applying factorial design and response surface methodology (RSM) with SAS and PSIPLOT programs. A second-order mathematical model was obtained to predict the yield as a function of methanol/oil molar ratio, catalyst concentration, reaction temperature, and rate of mixing. Based on ridge max analysis and RSM, as well as economic cost consideration, the practical optimal condition for the production of biodiesel was found to be: methanol/oil molar ratio, 7.9; temperature, 53 …

Design Principles For High School Engineering Design Challenges: Experiences From High School Science Classrooms, Christian Schunn Jan 2011

Design Principles For High School Engineering Design Challenges: Experiences From High School Science Classrooms, Christian Schunn

Publications

At the University of Pittsburgh, we have been exploring a range of approaches to design challenges for implementation in high school science classrooms (Apedoe, Reynolds, Ellefson, & Schunn, 2008; Ellefson, Brinker, Vernacchio, & Schunn, 2008; Schunn, Silk, & Apedoe, in press). In general, our approach has always involved students working during class time over the course of many weeks. So, our understanding of what works must be contextualized to that situation (i.e., without significant home support, by students enrolled in traditional classrooms, involving content that is connected to traditional science classrooms). However, our approach has been implemented with thousands of …

Infusing Engineering Design Into High School Stem Courses, Morgan Hynes, Merredith Portsmore, Emily Dare, Elissa Milto, Chris Rogers, David Hammer, Adam Carberry

Publications

Society is recognizing the need to improve STEM education and introduce engineering design concepts before college. In the recent National Academy of Engineers report, Engineering in K-12 Education: Understanding the Status and Improving the Prospects, the authors suggest that the STEM disciplines not be treated as ―silos‖ and that engineering might serve as a motivating context to integrate the four STEM disciplines (Katehi, Pearson, & Feder, 2009). Recent research has suggested that integrated technology and engineering design curriculum can serve as a positive model for mathematics and science learning and retention (Ortiz, 2010; Wendell, 2011).

We present the results of a comprehensive study of the gamma-ray burst 080928 and of its afterglow. GRB 080928 was a long burst detected by Swift/BAT and Fermi/GBM. It is one of the exceptional cases where optical emission had already been detected when the GRB itself was still radiating in the gamma-ray band. For nearly 100 s simultaneous optical, X-ray and gamma-ray data provide a coverage of the spectral energy distribution of the transient source from about 1 eV to 150 keV. In particular, we show that the SED during the main prompt emission phase agrees with synchrotron radiation. We …

Transit System Evaluation Process: From Planning To Realization, K Bartman, Jennifer Ogle, Mashrur Chowdhury, Anne Dunning

Publications

Many frameworks exist to help transit agencies plan, operate, and monitor the performance of transit in rural and urban communities. No framework integrates these three critical business practices into one coherent and flexible framework useful to rural and small-sized cities. The primary objective of this research was to integrate planning, operations, and performance measurement activities into a framework designed to evaluate transit in the context of overall mobility. By combining planning, evaluation, and performance monitoring processes, a succinct framework useful to transit agencies and planners was created. In addition to city entities, colleges and universities operating or contracting transit systems …

Immunization With Hiv Gag Targeted To Dendritic Cells Followed By Recombinant New York Vaccinia Virus Induces Robust T-Cell Immunity In Nonhuman Primates, Barbara J. Flynn, Kathrin Kastenmüller, Ulrike Wille-Reece

Publications

Protein vaccines, if rendered immunogenic, would facilitate vaccine development against HIV and other pathogens. We compared in nonhuman primates (NHPs) immune responses to HIV Gag p24 within 3G9 antibody to DEC205 ("DEC-HIV Gag p24"), an uptake receptor on dendritic cells, to nontargeted protein, with or without poly ICLC, a synthetic double stranded RNA, as adjuvant. Priming s.c. with 60 ?g of both HIV Gag p24 vaccines elicited potent CD4+ T cells secreting IL-2, IFN-γ, and TNF-α, which also proliferated. The responses increased with each of three immunizations and recognized multiple Gag peptides. DEC-HIV Gag p24 showed better cross-priming for …

Newcastle Disease Virus Expressing A Dendritic Cell-Targeted Hiv Gag Protein Induces A Potent Gag-Specific Immune Response In Mice, Jad Mammary, Frida Array, Qinshan Gao

Publications

Viral vaccine vectors have emerged as an attractive strategy for the development of a human immunodeficiency virus (HIV) vaccine. Recombinant Newcastle disease virus (rNDV) stands out as a vaccine vector since it has a proven safety profile in humans, it is a potent inducer of both alpha interferon (IFN-α) and IFN-β) production, and it is a potent inducer of dendritic cell (DC) maturation. Our group has previously generated an rNDV vector expressing a codon-optimized HIV Gag protein and demonstrated its ability to induce a Gag-specific CD8+ T cell response in mice. In this report we demonstrate that the Gag-specific …

Integrating Engineering Design Challenges Into Secondary Stem Education, Ronald L. Carr Jan 2011

Integrating Engineering Design Challenges Into Secondary Stem Education, Ronald L. Carr

Publications

Engineering is being currently taught in the full spectrum of the P-12 system, with an emphasis on design-oriented teaching (Brophy, Klein, Portsmore, & Rogers, 2008). Due to only a small amount of research on the learning of engineering design in elementary and middle school settings, the community of practice lacks the necessary knowledge of the trajectory of students' learning progressions towards design mastery and expertise and the appropriateness of otherwise established design pedagogies. The issue is even more pressing since many states are embedding engineering into their standards without a clear notion of how engineering (often conceptualized as design) works …

Observations On Braided Thin Wire Nucleate Boiling In Microgravity, Justin P. Koeln, Jeffrey C. Boulware, Heng Ban, Jr Dennison

Publications

A microgravity experiment was conducted on the Space Shuttle Endeavor (STS-108) to observe sustained nucleate boiling of water. Subcooled water was boiled with a single strand and a braid of three 0.16. mm diameter and 80. mm long Nichrome resistive wires. A CCD video camera recorded the experiment while six thermistors recorded the temperature of the fluid at various distances from the heating element. This paper reports experimental results in observations, measurements, and data analysis. Bubble explosions were found to take place shortly after the onset of boiling for both the single and braid of wires. The explosion may produce …

Loblolly pine (LP; Pinus taeda L.) is the most economically important tree in the U.S. and a cornerstone species in southeastern forests. However, genomics research on LP and other conifers has lagged behind studies on flowering plants due, in part, to the large size of conifer genomes. As a means to accelerate conifer genome research, we constructed a BAC library for the LP genotype 7-56. The LP BAC library consists of 1,824,768 individually-archived clones making it the largest single BAC library constructed to date, has a mean insert size of 96 kb, and affords 7.6X coverage of the 21.7 Gb …
