    Second Language Teaching Strategies for Teaching the Human Body to Fourth Graders

    Get PDF
    In a country filled with pressure for high academic achievement at the state and federal levels, it is necessary to implement best practice teaching strategies for student success. Best practice teaching strategies are strategies that are research based and have proven to be essential in increasing academic achievement. Among using best practices, there are a variety of programs that focus on teaching second language learners English, one of them being dual language. Dual language is an additive bilingual program in which the second language is taught through the content areas as the native language continues to be developed. However, the necessary materials and resources are not always available to the minority language teacher. The focus of this project was to develop a unit of science lessons on the human body that were aligned with national and state standards and that encompassed second language teaching strategies to maximize student learning and achievement. The development and research of the project are further discussed in the report

    Troubleshooting Time-Dependent Density-Functional Theory for Photochemical Applications: Oxirane

    Get PDF
    The development of analytic-gradient methodology for excited states within conventional time-dependent density-functional theory (TDDFT) would seem to offer a relatively inexpensive alternative to better established quantum-chemical approaches for the modeling of photochemical reactions. However, even though TDDFT is formally exact, practical calculations involve the use of approximate functionals, in particular the TDDFT adiabatic approximation, whose use in photochemical applications must be further validated. Here, we investigate the prototypical case of the symmetric CC ring opening of oxirane. We demonstrate by direct comparison with the results of high-quality quantum Monte Carlo calculations that, far from being an approximation on TDDFT, the Tamm-Dancoff approximation (TDA) is a practical necessity for avoiding triplet instabilities and singlet near instabilities, thus helping maintain energetically reasonable excited-state potential energy surfaces during bond breaking. Other difficulties one would encounter in modeling oxirane photodynamics are pointed out but none of these is likely to prevent a qualitatively correct TDDFT/TDA description of photochemistry in this prototypical molecule.Comment: 19 pages, 17 figures, submitted to the Journal of Chemical Physic

    Gipsy 3D: Analysis, Visualization and Vo-Tools

    Get PDF
    The scientific goals of the AMIGA project are based on the analysis of a significant amount of spectroscopic 3D data. In order to perform this work we present an initiative to develop a new VO compliant package, including present core applications and tasks offered by the Groningen Image Processing System (GIPSY), and new ones based on use cases elaborated in collaboration with ad- vanced users. One of the main goals is to provide local interoperability between GIPSY (visualization and data analysis) and other VO software. The connectivity with the Virtual Observatory environment will provide general access to 3D data VO archives and services, maximizing the potential for scientific discovery.Comment: 2 pages, 1 figure, to appear in the proceedings of the "Multi-wavelength Astronomy and Virtual Observatory" Workshop held at ESAC 1-3 Dec 200

    Immunologic and Inflammatory Reactions to Exogenous Stem Cells Implications for Experimental Studies and Clinical Trials for Myocardial Repair

    Get PDF
    Intense research is under way to determine the optimal stem cell type and regimen for repairing diseased myocardium. Although initial studies in humans focused on the use of homologous stem cells, allogeneic or xenogeneic stem cells have been studied extensively in experimental work. Clinical trials with allogeneic stem cells are now under way, an approach based on the premise that stem cells and precursor cells are characterized as being immunotolerant. However, evidence indicates that stem cells may gain immune potency in vivo, especially when delivered to inflamed tissue, such as acutely infarcted myocardium. Histopathologic studies show the presence of a lymphohistiocytic inflammatory reaction at the sites of delivery of allogeneic stem cells, a response that is exaggerated with the use of xenogeneic stem cells. The immune-mediated inflammatory reaction to allogeneic and xenogeneic stem cells may elicit a spectrum of effects, ranging from beneficial (e.g., increased paracrine activity) to detrimental (e.g., accelerated damage and removal of stem cells). Although the issue of immune-mediated inflammatory responses to non-self stem cells requires further evaluation, non-self stem cells should not be considered as immunologically inert or exclusively immunosuppressive in vivo

    Improving the Basic Communication Course: Assessing the Core Components

    Get PDF
    This study seeks to examine the effective means of assessing whether goals and objectives set within a basic communication course are met. The study outlines specific techniques used to evaluate learning outcomes to ensure that the course retains its relevance and general education status. A pretest-posttest design is utilized to determine whether students’ scores on cognitive, behavioral, and affective assessment instruments improve from the beginning to the end of the semester. Results indicate students’ scores improved on each of the primary learning indicators for the course including: an assessment of communication knowledge, conflict management skills, and intercultural communication apprehension. Discussion and implications for the basic communication course are included

    Semiclassical Wigner Theory of Photodissociation in Three Dimensions: Shedding Light on Its Basis

    14 págs.; 10 figs.; 5 apps.The semiclassical Wigner theory (SCWT) of photodissociation dynamics, initially proposed by Brown and Heller [J. Chem. Phys. 75, 186 (1981)] in order to describe state distributions in the products of direct collinear photodissociations, was recently extended to realistic three-dimensional triatomic processes of the same type [Arbelo-González et al., Phys. Chem. Chem. Phys. 15, 9994 (2013)]. The resulting approach, which takes into account rotational motions in addition to vibrational and translational ones, was applied to a triatomic-like model of methyl iodide photodissociation and its predictions were found to be in nearly quantitative agreement with rigorous quantum results, but at a much lower computational cost, making thereby SCWT a potential tool for the study of polyatomic reaction dynamics. Here, we analyse the main reasons for this agreement by means of an elementary model of fragmentation explicitly dealing with the rotational motion only. We show that our formulation of SCWT makes it a semiclassical approximation to an approximate planar quantum treatment of the dynamics, both of sufficient quality for the whole treatment to be satisfying.
