Parent Perspectives of Diabetes Management in Schools

Purpose The purpose of this study is to investigate parent reports of the diabetes care support their children receive in school, their concerns about diabetes management in school, and their knowledge of federal laws that protect children with diabetes. In addition, the study explores ethnic and socioeconomic status differences in diabetes management in school. Methods An ethnically heterogeneous sample of 309 parents of children with diabetes was recruited from a community-based and a university-based diabetes outpatient clinic. Parents completed a survey assessing supports their childs school provides for diabetes care, worries about diabetes care in school, and awareness of federal laws that pertain to children with diabetes. Results Many children did not have a written care plan or a nurse at school, but significantly more white children had these supports than Hispanic or black children. Most children were not allowed to check blood glucose levels or administer insulin in class. Most parents were worried about hyperglycemia and hypoglycemia in school, and most were not at all or only a little confident in the schools ability to care for diabetes. Most parents were not aware of federal laws, but high-income and white parents were more likely to be aware. Conclusions According to parents in the current study, children receive inadequate diabetes management support in schools. Minority children are less likely to receive supports than white children. Parents are worried about diabetes management in school, but most do not have the knowledge of federal laws necessary to protect their children.

Psychometric Findings for a Spanish Translation of the Diabetes Self-Management Profile (DSMP-Parent-Sp)

OBJECTIVE Few validated measures exist to evaluate self-management of diabetes in families with limited English proficiency. The present study evaluated the psychometric properties and the factorial equivalence of a Spanish translation of the parent report version of the Diabetes Self-Management Profile (DSMP-Parent-Sp). RESEARCH DESIGN AND METHODS Hispanic families of youth (mean 13.7 years old) with type 1 diabetes were recruited from three clinics in South Florida and represented a wide range of nationalities and acculturation levels. A total of 127 parents reported on their childs self-management behaviors using either the original DSMP-Parent (59.8%) or the DSMP-Parent-Sp (40.2%). In addition, youth reported their self-management using the original DSMP in English, and physicians rated their perceptions of the youths self-management. Glycemic control was indexed by A1C in the past 3 months and collected from medical chart review. RESULTS Item analysis confirmed that the DSMP-Parent-Sp items related to the overall composite score in expected ways, and internal consistency estimates were adequate. Paired correlations demonstrated strong parent-child concordance and a significant relationship with physician perceptions of self-management. Evidence of concurrent and convergent validity, as well as “strict factorial invariance,” was demonstrated. CONCLUSIONS These preliminary findings indicate that the DSMP-Parent-Sp is a reliable and valid parent report measure of the diabetes self-management behaviors of Hispanic youths. In addition, there is preliminary evidence that the translated measure may be considered equivalent to the original English measure when used to measure self-management in Hispanic youth with diabetes.

Study of Z Boson Production in PbPb Collisions at √sNN=2.76 TeV

A search for Z bosons in the μ+μ− decay channel has been performed in PbPb collisions at √ sNN = 2.76 TeV with the CMS detector at the LHC, in a 7.2 μb−1 data sample. The number of opposite-sign muon pairs observed in the 60–120 GeV/c2 invariant mass range is 39, corresponding to a yield per unit of rapidity (y) and per minimum bias event of (33.8± 5.5(stat) ± 4.4(syst)) × 10−8, in the |y| < 2.0 range. Rapidity, transverse momentum, and centrality dependencies are also measured. The results agree with next-to-leading order QCD calculations, scaled by the number of incoherent nucleon-nucleon collisions.

Search for exotic particles decaying to WZ in pp collisions at √s=7 TeV

A bstractA search for new exotic particles decaying to the VZ final state is performed, where V is either a W or a Z boson decaying into two overlapping jets and the Z decays into a pair of electrons, muons or neutrinos. The analysis uses a data sample of pp collisions corresponding to an integrated luminosity of 5 fb−1 collected by the CMS experiment at the LHC at

Erratum: Measurement of the tt¯ production cross section in the dilepton channel in pp collisions at √s = 8 TeV

TeV in 2011. No significant excess is observed in the mass distribution of the VZ candidates compared with the background expectation from standard model processes. Model-dependent upper limits at the 95% confidence level are set on the product of the cross section times the branching fraction of hypothetical particles decaying to the VZ final state as a function of mass. Sequential standard model W′ bosons with masses between 700 and 940 GeV are excluded. In the Randall-Sundrum model for graviton resonances with a coupling parameter of 0.05, masses between 750 and 880 GeV are also excluded.

Measurements of inclusive W and Z cross sections in pp collisions at ps = 7 TeV

A search is presented for a massive particle, generically referred to as a Z, decaying into a t t-bar pair. The search focuses on Z resonances that are sufficiently massive to produce highly Lorentz-boosted top quarks, which yield collimated decay products that are partially or fully merged into single jets. The analysis uses new methods to analyze jet substructure, providing suppression of the non-top multijet backgrounds. The analysis is based on a data sample of proton-proton collisions at a center-of-mass energy of 7 TeV, corresponding to an integrated luminosity of 5 inverse femtobarns. Upper limits in the range of 1 pb are set on the product of the production cross section and branching fraction for a topcolor Z modeled for several widths, as well as for a Randall--Sundrum Kaluza--Klein gluon. In addition, the results constrain any enhancement in t t-bar production beyond expectations of the standard model for t t-bar invariant masses larger than 1 TeV.A search is presented for a massive particle, generically referred to as a Z′, decaying into a tt− pair.

Measurement of the inclusive W and Z production cross sections in pp collisions at ps = 7TeV with the CMS experiment

In this study, the top-antitop quark (tt¯) production cross section is measured in proton-proton collisions at √s = 8 TeV with the CMS experiment at the LHC, using a data sample corresponding to an integrated luminosity of 5.3 fb–1. The measurement is performed by analysing events with a pair of electrons or muons, or one electron and one muon, and at least two jets, one of which is identified as originating from hadronisation of a bottom quark. The measured cross section is 239±2 (stat.)±11 (syst.)±6 (lum.) pb, for an assumed top-quark mass of 172.5 GeV, in agreement with the prediction of the standard model.

Strange particle production in pp collisions at ps = 0.9 and 7 TeV

Measurements of inclusive W and Z boson production cross sections in pp collisions at sqrt(s)=7 TeV are presented, based on 2.9 inverse picobarns of data recorded by the CMS detector at the LHC. The measurements, performed in the electron and muon decay channels, are combined to give sigma(pp to WX) times B(W to muon or electron + neutrino) = 9.95 pm 0.07(stat.) pm 0.28(syst.) pm 1.09(lumi.) nb and sigma(pp to ZX) times B(Z to oppositely charged muon or electron pairs) = 0.931 pm 0.026(stat.) pm 0.023(syst.) pm 0.102(lumi.) nb. Theoretical predictions, calculated at the next-to-next-to-leading order in QCD using recent parton distribution functions, are in agreement with the measured cross sections. Ratios of cross sections, which incur an experimental systematic uncertainty of less than 4%, are also reported.Measurements of inclusive W and Z boson production cross sections in pp collisions at
