If You See Something, Say Something: A Look at Experimental Writing on Art

Signs all over New York City state, If you see something, say something, but museum studies repeatedly find viewers do not attend to pictures, just as eye witness testimony is invariably skewed. Ways of seeing have been limited to known ways of discussing. Alternative approaches offer new insights. The first section, Experiments in Art Writing, examines two texts: T.J. Clark\u27s The Sight of Death, a journal of his daily visits looking at two Poussin paintings, for which he maintains the ambiguity of exploration and argues to keep visual images from their dissolution into political symbols; and, Charles Simic\u27s Dime Store Alchemy: The Art of Joseph Cornell, which foregrounds the imaginative as necessary to a critical reception of art. The second section, Literary Ekphrases as Art History and Theory, examines a passage in Proust and a poem by William Carlos Williams to suggest that poetry and prose fiction not only introduce readers to art history but are extensions of the discussed visual works\u27 own art history, and then turns to Don DeLillo\u27s Point Omega to study the arguments around representation as voiced and experienced by the characters, and to suggest a move away from the concept of representation. The final section, The Writing on the Wall, analyzes captions from Tate Modern\u27s little-known but significant caption project Bigger Picture to develop a theoretical validation for such an experimental program. These authors show us how they see rather than simply what they see, and so reveal the advantages and dangers in their choices, recommending we develop renditions of what we see, where to see means both a visual ability and an articulate response

THE EFFECTS OF AN INTERACTIVE VOCABULARY STRATEGY ON TEACHERS’ AND STUDENTS’ PERCEPTIONS OF WORD LEARNING

It is a well established fact that the level and degree of vocabulary knowledge plays an important role in adolescents’ literacy development. The purpose of this study was to examine teachers’ and students’ perceptions and use of an interactive vocabulary strategy, in the form of an interactive word wall, as the focal point of systematic instruction in a vocabulary-rich literacy program. An interactive word wall is an instructional tool for supporting word learning activities in which students explore, evaluate, reflect, and apply word meanings in meaningful contexts (Harmon, Wood, Vintinner, & Willeford, 2009). A sociocultural theory served as the theoretical framework to guide this study. Sociocultural theory emphasizes that knowledge is constructed collaboratively in a social context, which the individual and social world have mutually interrelated roles in the learning development. Based on a qualitative inquiry, a case study design was used to examine teacher and student perceptions, use, and adaptations of the interactive word wall. This study employed interviews, observations, assessments, surveys, knowledge rating scales, and artifact data. This research study was conducted over six weeks during the fall of 2010. Participants included four content area teachers and their students in one urban middle school in the southeastern United States. Each content area (mathematics, science, social studies, and language arts) is represented in this study. Within-case and cross-case analyses were used to analyze the data. The main findings from this study are: (1) Teachers and students viewed the interactive vocabulary strategy as being beneficial in enhancing word learning in their content area, (2) Student choice is an important factor to consider when planning instructional strategies in content area classrooms, (3) Teacher resistance to vocabulary instruction decreased over time as they adapted the interactive word wall strategy to meet their specific content goals, and (4) Student word knowledge broadened and deepened during the interactive word wall instructional design. Several conclusions and implications are drawn from the findings. Recommendations for future research are also discussed in the final chapter of this study

Measurement of the resonant and CP components in B¯ 0 → J=ψπþπ− decays

The resonant structure of the reaction B¯0→J/ψπ+π− is studied using data from 3  fb−1 of integrated luminosity collected by the LHCb experiment, one third at 7 TeV center-of-mass energy and the remainder at 8 TeV. The invariant mass of the π+π− pair and three decay angular distributions are used to determine the fractions of the resonant and nonresonant components. Six interfering π+π− states, ρ(770), f0(500), f2(1270), ρ(1450), ω(782) and ρ(1700), are required to give a good description of invariant mass spectra and decay angular distributions. The positive and negative charge parity fractions of each of the resonant final states are determined. The f0(980) meson is not seen and the upper limit on its presence, compared with the observed f0(500) rate, is inconsistent with a model where these scalar mesons are formed from two quarks and two antiquarks (tetraquarks) at the eight standard deviation level. In the qq¯ model, the absolute value of the mixing angle between the f0(980) and the f0(500) scalar mesons is limited to be less than 17° at 90% confidence level

Measurement of CP asymmetry in D 0 → K - K + and D 0 → π - π decays

Time-integrated CP asymmetries in D 0 decays to the final states K - K + and π - π + are measured using proton-proton collisions corresponding to 3fb-1 of integrated luminosity collected at centre-of-mass energies of 7 TeV and 8 TeV. The D 0 mesons are produced in semileptonic b-hadron decays, where the charge of the accompanying muon is used to determine the initial flavour of the charm meson. The difference in CP asymmetries between the two final states is measured to be Δ ACP = ACP (K- K +) ACP (π- π+) = (+ 0.14 ± 0.16 (stat) ± 0.08 (syst)) %. A measurement of A CP (K - K +) is obtained assuming negligible CP violation in charm mixing and in Cabibbo-favoured D decays. It is found to be ACP (K- K+) = (- 0.06 ± 0.15 (stat) ± 0.10 (syst)) %, where the correlation coefficient between ΔA CP and A CP (K - K +) is ρ = 0.28. By combining these results, the CP asymmetry in the D 0 → π - π + channel is A CP (π - π +) = (-0.20 ± 0.19 (stat) ± 0.10 (syst))%

Measurement of the Xi(-)(b) and Omega(-)(b) baryon lifetimes

Using a data sample of pp collisions corresponding to an integrated luminosity of 3 fb−1, the Ξ−b and Ω−b baryons are reconstructed in the Ξ−b → J/ψΞ− and Ω−b → J/ψΩ− decay modes and their lifetimes measured to be τ(Ξ−b) = 1.55+0.10−0.09 (stat) ± 0.03 (syst) ps, τ(Ω−b) = 1.54+0.26−0.21 (stat) ± 0.05 (syst) ps. These are the most precise determinations to date. Both measurements are in good agreement with previous experimental results and with theoretical predictions

Measurement of ψ(2S) polarisation in pp collisions at √s = 7 TeV

The polarisation of prompt ψ(2S) mesons is measured by performing an angular analysis of ψ(2S) → μ+μ- decays using proton-proton collision data, corresponding to an integrated luminosity of 1.0 fb-1, collected by the LHCb detector at a centre-of-mass energy of 7 TeV. The polarisation is measured in bins of transverse momentum pT and rapidity y in the kinematic region 3.5 < pT < 15 GeV/c and 2.0 < y < 4.5, and is compared to theoretical models. No significant polarisation is observed

Measurement of the CP-violating phase phi(s) in (B)over-bar(s)(0) -> J / psi pi(+)pi(-) decays

The mixing-induced CP -violating phase ϕs in View the MathML source and View the MathML source decays is measured using the J/ψπ+π− final state in data, taken from 3 fb−1 of integrated luminosity, collected with the LHCb detector in 7 and 8 TeV centre-of-mass pp collisions at the LHC. A time-dependent flavour-tagged amplitude analysis, allowing for direct CP violation, yields a value for the phase ϕs=70±68±8 mrad. This result is consistent with the Standard Model expectation and previous measurements

Study of beauty hadron decays into pairs of charm hadrons

First observations of the decays Λb 0 → Λc +D(s) - are reported using data corresponding to an integrated luminosity of 3fb-1 collected at 7 and 8 TeV center-of-mass energies in proton-proton collisions with the LHCb detector. In addition, the most precise measurement of the branching fraction B(Bs 0→D+Ds -) is made and a search is performed for the decays B(s) 0→Λc +Λc -. The results obtained are B(Λb 0→Λc +D-)/ B(Λb 0→Λc +D s -)=0.042±0.003(stat)±0.003(syst), [B(Λb 0→Λc +D s -)/B(B̄0→D+D s -)]/[B(Λb 0→Λ c +π-)/B(B̄0→D +π-)]=0.96±0.02(stat)±0.06(syst),B(B s 0→D+Ds -)/ B(B̄0→D+Ds -)=0. 038±0.004(stat)±0.003(syst),B(B̄0→Λ c +Λc -)/B(B̄ 0→D+Ds -)<0.0022[95%C.L.], B(Bs 0→Λc +Λ c -)/B(Bs 0→D+D s -)<0.30[95%C.L.]. Measurement of the mass of the Λb 0 baryon relative to the B̄0 meson gives M(Λb 0)-M(B̄0)=339. 72±0.24(stat)±0.18(syst)MeV/c2. This result provides the most precise measurement of the mass of the Λb 0 baryon to date

Effective lifetime measurements in the B-s(0) -> K+K-, B-0 -> K+pi(-) and B-s(0) -> pi K-+(-) decays

Measurements of the effective lifetimes in the View the MathML source, B0→K+π− and View the MathML source decays are presented using 1.0 fb−1 of pp collision data collected at a centre-of-mass energy of 7 TeV by the LHCb experiment. The analysis uses a data-driven approach to correct for the decay time acceptance. This is the most precise determination to date of the effective lifetime in the View the MathML source decay and provides constraints on contributions from physics beyond the Standard Model to the View the MathML source mixing phase and the width difference ΔΓs
