    Implementation and perceived benefits of an after-school soccer program designed to promote social and emotional learning: A multiple case study

    Social and emotional learning (SEL) competencies such as self-awareness and relationship skills are predictors of academic success, overall well-being, and avoidance of problematic behaviors. Among school-aged children, research has demonstrated that well-implemented programs teach SEL competencies and life skills (e.g., leadership, responsible decision making) that can transfer to other settings. Similar claims have been made in the field of sport-based youth development (SBYD), however, the SEL framework has not been widely applied in sport programming. Implementation, student learning, and transfer of learning in SBYD programs designed to promote SEL require further exploration. Therefore, the current study examined the implementation and perceived benefits of an after-school soccer program designed to promote SEL. Participants were six coaches and 51 students from three different sites where this program is offered. A multiple case study design was used, integrating data from customized feedback surveys, interviews, systematic observation, and field notes. Results indicated the program reflects many SBYD best practices. Although implementation varied between sites, program culture and core values were consistent. Evidence indicated students learned and applied SEL lessons in the soccer program and that transfer beyond the program was promoted. Participants were most likely to report transfer to the school setting, therefore, future studies should examine this topic more directly. Other implications for research and program implementation are discussed

    Using Video-Based Instruction To Integrate Ethics Into The Curriculum

    This paper describes a video case discussion project based on the IMA’s Statement of Ethical Professional Practice that was administered in a cost accounting class to assess the extent to which students were able to identify and discuss ethical issues raised by the facts of a case scenario. The case was developed by the IMA to advance the continuing education in ethics of financial executives and management accountants. The scenario realistically portrays the kind of pressures faced by management accountants to go along with top management decisions that are driven by self-interest rather than proper accounting. We use a highly structured approach for direct assessment of student learning with pre-established rubrics. Indirect assessment of learning is approximated by a survey of students’ subjective reactions. In general, we conclude IMA’s video Success without Compromise provides an opportunity for students to apply ethics standards in a realistic setting and encourages students to become active participants in the learning experience

    Morphology of Anion-Conducting Ionenes Investigated by X-ray Scattering and Simulation

    Get PDF
    We have studied the morphology of a novel series of benzimidazole-based ionenes, methylated poly(hexamethyl-p-terphenylbenzimidazolium) (HMT-PMBI), in halide form. Materials with anion-exchange capacities ranging from 0 to 2.5 mequiv/g were studied. X-ray scattering reveals three length scales in the materials: ion–polymer spacing (4 Å), polymer–polymer interchain spacing (6 Å), and an intrachain repeat distance (20 Å). No long-range structure is apparent above the monomer length, which is rare in ion-conducting polymer membranes. In preliminary molecular dynamics simulations, water molecules were observed forming chains between ions, even at a modest level of hydration, providing an interpenetrating network where conductivity can occur

    Modeling and experimental results for condensing supercritical CO2 power cycles.

    This Sandia supported research project evaluated the potential improvement that 'condensing' supercritical carbon dioxide (S-CO{sub 2}) power cycles can have on the efficiency of Light Water Reactors (LWR). The analytical portion of research project identified that a S-CO{sub 2} 'condensing' re-compression power cycle with multiple stages of reheat can increase LWR power conversion efficiency from 33-34% to 37-39%. The experimental portion of the project used Sandia's S-CO{sub 2} research loop to show that the as designed radial compressor could 'pump' liquid CO{sub 2} and that the gas-cooler's could 'condense' CO{sub 2} even though both of these S-CO{sub 2} components were designed to operate on vapor phase S-CO{sub 2} near the critical point. There is potentially very high value to this research as it opens the possibility of increasing LWR power cycle efficiency, above the 33-34% range, while lowering the capital cost of the power plant because of the small size of the S-CO{sub 2} power system. In addition it provides a way to incrementally build advanced LWRs that are optimally designed to couple to S-CO{sub 2} power conversion systems to increase the power cycle efficiency to near 40%

    Nestling Sex Ratios Do Not Support Long-Term Parity In Two Species With Different Life-History Strategies

    To maximize fitness, breeding adults may respond to environmental processes by adjusting their progeny’s sex ratios. R. A. Fisher in 1930 hypothesized that frequency-dependent selection would result in equal investment in sons and daughters over the long term, yielding a balanced sex ratio if the costs of raising a son and daughter are equal. Diverse hypotheses have tried to explain population and brood-by-brood deviations from this mean as well as annual variation by focusing on adult sex ratios, resources, abiotic conditions, and female and male quality. We collected data in 2002-2010 to explore population-level variation in nestling sex ratios in 2 migratory grassland songbird species: the Bobolink (Dolichonyx oryzivorus) and Savannah Sparrow (Passerculus sandwichensis). These species differ in migratory strategy (long-distance vs. short-distance), and morphological dimorphism. Fisher’s hypothesis was rejected for Savannah Sparrows (n = 684 nestlings; 39% male) but not rejected for Bobolinks (n = 390 nestlings; 53.8% male). No relationship was found between nestling and adult sex ratios measured in the same year. In descriptive analyses at the brood level, male and female body size and age, and ecological conditions (temperature and precipitation) failed to predict nestling sex ratios. Although male nestlings were heavier than female nestlings and resource availability changed through the season, these factors did not influence sex ratios relative to female body size or seasonality. For Savannah Sparrows, larger broods tended to be male-biased. While we were otherwise not able to explain deviation in offspring sex ratio for Savannah Sparrows, our results suggest that the ecological and evolutionary pressures that affect sex ratios may be both species- and population-specific
