Spirituality and Subjective Well-Being: Evidences for a New Domain in the Personal Well-Being Index

Abstract: Subjective well-being explores the evaluations, both positive and negative, of how people experience their lives. Research in the field inquires how people perceive their well-being in different settings, including different cultures, regions and cities. A large number of different measures have been designed to capture subjective well-being. One of the most used SWB measure is the Personal Well-being Index (PWI), an evaluation of life developed by Cummins et al [(2003). Social Indicators Research, 64, 159–190] which proposes that satisfaction with life consists of seven different life-domains. Theoretical considerations of the contribution of spirituality and religiosity to life satisfaction, from a eudaimonic (from the Greek, it consists of the word "eu" (good or well-being) and the word “daemon” (spirit)) point of view, led to test the contribution of this new domain in the prediction of the Personal Well-being Index (PWI) in Bogota, Colombia. Empirical results confirm the construct validity and reliability of the scale. The contribution of the new domain—satisfaction with spirituality and religiosity—to PWI was found significant. Based on these results the paper explores conceptually the role of spirituality contributing to satisfaction with life. The finding stresses the importance of interpreting satisfaction with life as a whole from the Aristotelian concept of eudaimonia. New questions for research in this important area are proposed

Measurement of differential top-quark-pair production cross sections in pp collisions at √s = 7TeV

Abstract: Normalised differential top-quark pair production cross sections are measured in pp collisions at a centre-of-mass energy of 7 TeV at the LHC with the CMS detector using data recorded in 2011 corresponding to an integrated luminosity of 5.0 inverse femtobarns. The measurements are performed in the lepton+jets decay channels (e+jets and mu+jets) and the dilepton decay channels (oppositely charged ee, mu mu, and e mu). The t t-bar differential cross section is measured as a function of kinematic properties of the final-state charged leptons and jets associated to b quarks, as well as those of the top quarks and the t t-bar system. The data are compared with several predictions from perturbative QCD calculations up to approximate next-to-next-to-leading-order precision. No significant deviations from the standard model are observed.

Measurement of the muon charge asymmetry in inclusive pp →w+X production at s =7TeV and an improved determination of light parton distribution functions

Abstract: Measurements of the muon charge asymmetry in inclusive pp to WX production at sqrt(s) = 7 TeV are presented. The data sample corresponds to an integrated luminosity of 4.7 inverse femtobarns recorded with the CMS detector at the LHC. With a sample of more than twenty million W to mu nu events, the statistical precision is greatly improved in comparison to previous measurements. These new results provide additional constraints on the parton distribution functions of the proton in the range of the Bjorken scaling variable x from 10E-3 to 10E-1. These measurements and the recent CMS measurement of associated W + charm production are used together with the cross sections for inclusive deep inelastic ep scattering at HERA in a next-to-leading-order QCD analysis. The determination of the valence quark distributions is improved, and the strange-quark distribution is probed directly through the leading-order process g + s to W + c in proton-proton collisions at the LHC.
