Barreiras e facilitadores percebidos por pessoas com deficiência praticantes de esportes

Considering the importance of including people with disabilities in sport, we aim to identify barriers and facilitators for the practice of sports by people with disabilities and that are included in the extension projects of the Federal University of Santa Catarina (Brazil). To determine barriers and facilitators, a questionnaire was applied to nineteen participants Chi-square test was used to assess the association between barriers and facilitators (p<0,05). Indicators statistically associated as facilitators for the practice of sports by people with disabilities include sympathy and professional knowledge, support from family and friends, and the absence of embarrassment to the practice. The presence of injuries, climate and distance from the practice site were associated as barriers. Thus, providing an environment of high social support, establishing care to avoid physical injuries and offering decentralized sports programs, in the city, seem to be important measures for effective people participation with disabilities in sports.Considerando la importancia de la inserción de personas con discapacidad en el deporte, el objetivo de este estudio fue identificar las barreras y facilitadores para la práctica deportiva de personas con discapacidad insertadas en los proyectos de extensión de la Universidad Federal de Santa Catarina (Brasil). Para barreras y facilitadores se aplicó un cuestionario a 19 participantes. Se utilizó el test Qui-cuadrado para evaluar la asociación entre barreras y facilitadores (p<0,05). Los indicadores estadísticamente asociados como facilitadores para la práctica de deportes de personas con discapacidad incluyen la simpatía y conocimientos profesional, apoyo de la familia y amigos y la ausencia de vergüenza para la práctica. Presencia de lesiones, el clima y la distancia del local de la práctica fueron asociados como barreras. Siendo así, proporcionar un ambiente de gran apoyo social, establecer cuidados para prevenir lesiones físicas y ofrecer programas deportivos descentralizados en la ciudad, parecen ser medidas importantes para una efectiva participación de personas con discapacidad en el deporte.Considerando a importância da inserção de pessoas com deficiência no esporte, objetivamos identificar as barreiras e os facilitadores para a prática esportiva de pessoas com deficiência inseridas nos projetos de extensão da Universidade Federal de Santa Catarina (Brasil).

Method: A quasi-experimental study was conducted with school children who attended two outpatient clinics of a university hospital. Data were collected by systematic observation of the self-monitoring of blood glucose (SMBG) technique before and after the intervention. Data analysis consisted of verifying changes while performing the technique, using pre- and post-intervention compliance rates using statistical tests. The sample consisted of 33 children. Each child participated in one session; 17 educational workshops were conducted in total. Results: We found an increased frequency of SMBG, changing lancets, rotation of puncture sites, as well as calibration and periodic checking of date and time of the glucose meter. Comparisons pre- and post-intervention showed that the average number of steps in accordance with the SMBG technique increased from 5.30 to 6.58, whereas the steps “Changing the lancet of the lancing device”, “Pressing the puncture site” and “Disposing of materials used in a needlestick container” showed statistically significant differences. Conclusion: The educational workshop was effective, as it improved children’s performance of the SBMG technique

Performance of CMS muon reconstruction in pp collision events at sqrt(s) = 7 TeV

The performance of muon reconstruction, identification, and triggering in CMS has been studied using 40 inverse picobarns of data collected in pp collisions at sqrt(s) = 7 TeV at the LHC in 2010. A few benchmark sets of selection criteria covering a wide range of physics analysis needs have been examined. For all considered selections, the efficiency to reconstruct and identify a muon with a transverse momentum pT larger than a few GeV is above 95% over the whole region of pseudorapidity covered by the CMS muon system, abs(eta) < 2.4, while the probability to misidentify a hadron as a muon is well below 1%. The efficiency to trigger on single muons with pT above a few GeV is higher than 90% over the full eta range, and typically substantially better. The overall momentum scale is measured to a precision of 0.2% with muons from Z decays. The transverse momentum resolution varies from 1% to 6% depending on pseudorapidity for muons with pT below 100 GeV and, using cosmic rays, it is shown to be better than 10% in the central region up to pT = 1 TeV. Observed distributions of all quantities are well reproduced by the Monte Carlo simulation.Comment: Replaced with published version. Added journal reference and DO

Search for the standard model Higgs boson in the H to ZZ to 2l 2nu channel in pp collisions at sqrt(s) = 7 TeV

A search for the standard model Higgs boson in the H to ZZ to 2l 2nu decay channel, where l = e or mu, in pp collisions at a center-of-mass energy of 7 TeV is presented. The data were collected at the LHC, with the CMS detector, and correspond to an integrated luminosity of 4.6 inverse femtobarns. No significant excess is observed above the background expectation, and upper limits are set on the Higgs boson production cross section. The presence of the standard model Higgs boson with a mass in the 270-440 GeV range is excluded at 95% confidence level.Comment: Submitted to JHE

Azimuthal anisotropy of charged particles at high transverse momenta in PbPb collisions at sqrt(s[NN]) = 2.76 TeV

The azimuthal anisotropy of charged particles in PbPb collisions at nucleon-nucleon center-of-mass energy of 2.76 TeV is measured with the CMS detector at the LHC over an extended transverse momentum (pt) range up to approximately 60 GeV. The data cover both the low-pt region associated with hydrodynamic flow phenomena and the high-pt region where the anisotropies may reflect the path-length dependence of parton energy loss in the created medium. The anisotropy parameter (v2) of the particles is extracted by correlating charged tracks with respect to the event-plane reconstructed by using the energy deposited in forward-angle calorimeters. For the six bins of collision centrality studied, spanning the range of 0-60% most-central events, the observed v2 values are found to first increase with pt, reaching a maximum around pt = 3 GeV, and then to gradually decrease to almost zero, with the decline persisting up to at least pt = 40 GeV over the full centrality range measured.Comment: Replaced with published version.

Measurement of the Z/gamma* + b-jet cross section in pp collisions at 7 TeV

The production of b jets in association with a Z/gamma* boson is studied using proton-proton collisions delivered by the LHC at a centre-of-mass energy of 7 TeV and recorded by the CMS detector. The inclusive cross section for Z/gamma* + b-jet production is measured in a sample corresponding to an integrated luminosity of 2.2 inverse femtobarns. The Z/gamma* + b-jet cross section with Z/gamma* to ll (where ll = ee or mu mu) for events with the invariant mass 60 < M(ll) < 120 GeV, at least one b jet at the hadron level with pT > 25 GeV and abs(eta) < 2.1, and a separation between the leptons and the jets of Delta R > 0.5 is found to be 5.84 +/- 0.08 (stat.) +/- 0.72 (syst.) +(0.25)/-(0.55) (theory) pb. The kinematic properties of the events are also studied and found to be in agreement with the predictions made by the MadGraph event generator with the parton shower and the hadronisation performed by PYTHIA.Comment: Submitted to the Journal of High Energy Physic

Search for New Physics with Jets and Missing Transverse Momentum in pp collisions at sqrt(s) = 7 TeV

A search for new physics is presented based on an event signature of at least three jets accompanied by large missing transverse momentum, using a data sample corresponding to an integrated luminosity of 36 inverse picobarns collected in proton--proton collisions at sqrt(s)=7 TeV with the CMS detector at the LHC. No excess of events is observed above the expected standard model backgrounds, which are all estimated from the data. Exclusion limits are presented for the constrained minimal supersymmetric extension of the standard model. Cross section limits are also presented using simplified models with new particles decaying to an undetected particle and one or two jets
