    With increased attention to teacher quality and accountability, instructional coaching has emerged as a popular form of teacher support and professional development in literacy and other areas of instruction. Despite significant interest from school personnel, researchers, and federal funders, there remains a lack of consensus around the key components and activities of instructional coaching. To that end, studies that use quantitative and qualitative methods can offer valuable information on the development and validation of coaching practices. This chapter briefly describes the Classroom Strategies Assessment System Coaching Model that draws on the adult learning and formative assessment literature. We offer key observations of educators' knowledge of and experience in instructional coaching from focus groups conducted with teachers in high-poverty, urban elementary schools. Directions for practice and research are discussed.Peer reviewe

    First evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)

    Assessing sweet sorghum juice and syrup quality and fermentation efficiency

    No full text
    Sweet sorghum is a C4 crop with high photosynthetic efficiency with a unique ability of high carbon assimilation (50 g m-2 day-1) and accumulates high concentrations of easily fermentable sugars (glucose, fructose and sucrose) in the stalks. Hence, it is widely believed that it is an alternate energy source that is renewable, sustainable, efficient, cost-effective, convenient and safe to use. Sucrose is the major sugar in sweet sorghum juice which constitutes up to 85% of the total sugars (Woods 2000). The sugar yields ranged between 1.6 to 13.2 Mg ha-1, with significant variations observed between years and regions (Jackson et al. 1980; Reddy et al. 2007; Zhao et al. 2009). The juice sugar content is dependent on the crop stage, because fructose is more abundant at the early development stage, whereas sucrose tends to be dominant after heading (Sipos et al. 2009). The sweet sorghum juice sugar content ranged from 10 to 25 Brix% at maturity (Reddy et al. 2007; Ritter et al. 2004). Research at the International Crops Research Institute for the Semi-Arid-Tropics (ICRISAT) showed that sweet sorghum juice yield ranges between 16.8 to 27.2 m3 ha-1 (Reddy et al. 2007) and accrues about 23% additional returns vis-à-vis grain sorghum (Rao et al. 2009)

    Measurement of the CP-violating phase \phi s in Bs->J/\psi\pi+\pi- decays

    No full text
    Measurement of the mixing-induced CP-violating phase phi_s in Bs decays is of prime importance in probing new physics. Here 7421 +/- 105 signal events from the dominantly CP-odd final state J/\psi pi+ pi- are selected in 1/fb of pp collision data collected at sqrt{s} = 7 TeV with the LHCb detector. A time-dependent fit to the data yields a value of phi_s=-0.019^{+0.173+0.004}_{-0.174-0.003} rad, consistent with the Standard Model expectation. No evidence of direct CP violation is found

    Observations of Bºs→ψ(2S)η and Bº(s)→ψ(2S)π+π- decays

    No full text
    First observations of the B0s →ψ(2S)η, B0 →ψ(2S)π + π − and B0s →ψ(2S)π + π − decays are made using a dataset corresponding to an integrated luminosity of 1.0 fb−1 collected by the LHCb experiment in proton–proton collisions at a centre-of-mass energy of √ s = 7 TeV. The ratios of the branching fractions of each of the ψ(2S) modes with respect to the corresponding J/ψ decays are B(B0s →ψ(2S)η) ÷ B(B0s →J/ψη) = 0.83± 0.14 (stat)±0.12 (syst) ±0.02 (B), ; B(B0→ψ(2S)π + π − ) ÷ B(B0→J/ψπ + π − ) = 0.56± 0.07 (stat)±0.05 (syst)± 0.01 (B), ; B(B0s →ψ(2S)π + π − ) ÷ B(B0s →J/ψπ + π − ) = 0.34± 0.04 (stat)±0.03 (syst)± 0.01 (B), where the third uncertainty corresponds to the uncertainties of the dilepton branching fractions of the J/ψ and ψ(2S) meson decays

    Measurement of the ratio of prompt χ c to J / ψ production in pp collisions at √s = 7 TeV

    No full text
    The prompt production of charmonium χ c and J / ψ states is studied in proton-proton collisions at a centre-of-mass energy of √s = 7 TeV at the Large Hadron Collider. The χ c and J / ψ mesons are identified through their decays χ c → J / ψ γ and J / ψ → μ + μ - using 36 pb - 1 of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for χ c and J / ψ, σ (χ c → J / ψ γ) / σ (J / ψ), is determined as a function of the J / ψ transverse momentum in the range 2 < p T J / ψ < 15 GeV / c. The results are in excellent agreement with next-to-leading order non-relativistic expectations and show a significant discrepancy compared with the colour singlet model prediction at leading order, especially in the low p T J / ψ region

    Este estudo apresenta uma caracterização climática do Estado da Bahia, utilizando probabilidades do balanço hídrico mensal. Na estimativa da probabilidade, dados de precipitação mensal de um período de 15 anos ou mais foram utilizados. A análise foi efetuada para 196 locais. Os valroes de evapotranspiração potencial para anos individuais, foram calculados utilizando a metodologia de Reddy * Amorim Neto (1983) e Reddy (1979). A técnica do balanço hídrico mensal de Thornthwaite & Mather (1955 e 1957) com algumas modificações foi utilizada na estimativa da evapotranspiração real, deficit hídrico e escorrimento superficial (runnoff). Com estes parametros, a probabilidade do déficit hídrico relativo a evapotranspiração potencial, e, do runnoff sob diferentes classes para cada mês, foi calculada e apresentada em tabelas para os 196 locais. A distruibuição espacial das médias e desvios padrões dos períodos úmidos, moderadamente úmidos e secos; o início do período úmido e moderadamente úmido e as probabilidades do período úmido com ... 3 meses; do período seco maior ou igual a 4 meses consecutivos e o período moderadamente úmido maior ou igual a 4 meses, foram graficamente descritas. A variação temporal da média móvel do período úmido de alguns locais são também apresentadas. Estes padrões demonstram claramente a não homogeneidade na série de dados de alguns locais. Para estes locais os resultados são completamente ambíguos
