Sacred communities: contestations and connections
This article discusses a project whose purpose was to review existing qualitative and quantitative data from two separate studies to provide new insights about everyday religion and belonging. Researchers engaged in knowledge exchange and dialogue with new and former research participants, with other researchers involved in similar research, and with wider academic networks beyond the core disciplines represented here, principally anthropology and geography. Key concluding themes related to the ambivalent nature of âfaithâ, connections over place and time, and the contested nature of community. Implicit in terms like âfaithâ, âcommunityâ, and âlife courseâ are larger interwoven narratives of space, time, place, corporeality, and emotion. The authors found that understanding how places, communities, and faiths differ and intersect requires an understanding of social relatedness and boundaries
Study of Beauty Hadron Decays into Pairs of Charm Hadrons
First observations of the decays A(b)(0) -> A(c)(+)D((s))(-) are reported using data corresponding to an integrated luminosity of 3 fb(-1) collected at 7 and 8 TeV center-of- ass energies in proton-proton collisions with the LHCb detector. In addition, the most precise measurement of the branching fraction B(B-s(0) -> D+Ds-) is made and a search is performed for the decays B-0((s)) -> A(c)(+)A(c)(-). The results obtained are B(A(b)(0) -> A(c)(+)D(-))/B(A(b)(0) -> A(c)(+)D(s)(-)) = 0.042 +/- 0.003 (stat) +/- 0.003 (syst), [B(A(b)(0) -> A(c)(+)D(s)(-))/B((B) over bar (0) -> D+Ds-)]/[B(A(b)(0) -> A(c)(+)pi(-))/B((B) over bar (0) -> D+pi(-))] = 0.96 +/- 0.02 (stat) +/- 0.06 (syst), B(B-s(0) -> D+Ds-)/B((B) over bar (0) -> D+Ds-) = 0.038 +/- 0.004 (stat) +/- (syst), B((B) over bar (0) -> A(c)(+)A(c)(-))/B((B) over bar (0) -> D+Ds-) A(c)(+)A(c)(-)) /B(B-s(0) -> D+Ds-) < 0.30[95% C.L.]. Measurement of the mass of the A(b)(0) baryon relative to the (B) over bar (0) meson gives M(A(b)(0)) Âż M((B) over bar (0)) = 339.72 +/- 0.24 (stat) +/- 0.18 (syst) MeV/c(2). This result provides the most precise measurement of the mass of the A(b)(0) baryon to date
The development and validation of a scoring tool to predict the operative duration of elective laparoscopic cholecystectomy
Background: The ability to accurately predict operative duration has the potential to optimise theatre efficiency and utilisation, thus reducing costs and increasing staff and patient satisfaction. With laparoscopic cholecystectomy being one of the most commonly performed procedures worldwide, a tool to predict operative duration could be extremely beneficial to healthcare organisations.
Methods: Data collected from the CholeS study on patients undergoing cholecystectomy in UK and Irish hospitals between 04/2014 and 05/2014 were used to study operative duration. A multivariable binary logistic regression model was produced in order to identify significant independent predictors of long (>â90 min) operations. The resulting model was converted to a risk score, which was subsequently validated on second cohort of patients using ROC curves.
Results: After exclusions, data were available for 7227 patients in the derivation (CholeS) cohort. The median operative duration was 60 min (interquartile range 45â85), with 17.7% of operations lasting longer than 90 min. Ten factors were found to be significant independent predictors of operative durations >â90 min, including ASA, age, previous surgical admissions, BMI, gallbladder wall thickness and CBD diameter. A risk score was then produced from these factors, and applied to a cohort of 2405 patients from a tertiary centre for external validation. This returned an area under the ROC curve of 0.708 (SEâ=â0.013, pââ90 min increasing more than eightfold from 5.1 to 41.8% in the extremes of the score.
Conclusion: The scoring tool produced in this study was found to be significantly predictive of long operative durations on validation in an external cohort. As such, the tool may have the potential to enable organisations to better organise theatre lists and deliver greater efficiencies in care
Study of beauty hadron decays into pairs of harm hadrons
First observations of the decays Î0bâÎ+cDâ(s) are reported using data corresponding to an integrated luminosity of 3ââfbâ1 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(B0sâD+Dâs) is made and a search is performed for the decays B0(s)âÎ+cÎâc. The results obtained are
B(Î0bâÎ+cDâ)/B(Î0bâÎ+cDâs)=0.042±0.003(stat)±0.003(syst),[B(Î0bâÎ+cDâs)B(BÂŻ0âD+Dâs)]/[B(Î0bâÎ+cÏâ)B(BÂŻ0âD+Ïâ)]=0.96±0.02(stat)±0.06(syst),B(B0sâD+Dâs)/B(BÂŻ0âD+Dâs)=0.038±0.004(stat)±0.003(syst),B(BÂŻ0âÎ+cÎâc)/B(BÂŻ0âD+Dâs)<0.0022[95%ââC.L.],B(B0sâÎ+cÎâc)/B(B0sâD+Dâs)<0.30[95%ââC.L.].
Measurement of the mass of the Î0b baryon relative to the BÂŻ0 meson gives M(Î0b)âM(BÂŻ0)=339.72±0.24(stat)±0.18(syst)ââMeV/c2. This result provides the most precise measurement of the mass of the Î0b baryon to date
