    The propensity of strongly identified fans to contribute positive organizational outcomes for sport teams underpins why team identification maintains a central position in sport management. In the present study we examine the multidimensional structure, stability, and interrelationships between the dimensions of team identification, using longitudinal data (April 2011-April 2012) collected from fans of a new Australian Rules football team (N=602). A Confirmatory Factor Analysis (CFA) of the team identification items included (measured using the Team*ID scale), supported a five-dimensional model structure. This model was subsequently computed as a longitudinal CFA to test the configural and metric invariance of the Team*ID scale. We used a cross-lagged panel model to examine the longitudinal stability of, and interrelationships between,the dimensions: affect, behavioral involvement, cognitive awareness, private evaluation, and public evaluation. Each dimension displayed relative stability over time. In addition, public evaluation and private evaluation in April 2011 displayed a positive relationship with behavioral involvement in April 2012. Similarly, cognitive awareness in April 2011 predicted increases in public evaluation in April 2012 two. We conclude with implications for theory and practice

    Sport Consumer Behavior Research: Improving Our Game

    Get PDF
    Sport consumer behavior (SCB) research continues to grow in both popularity and sophistication. A guiding principle in much of this research is that sport consumers seek out sport related experiences, and the benefits they yield, in order to satisfy needs and wants. This approach has provided new knowledge and insight into sport consumers. One outcome of this focus is that the vast majority of research on sport consumers has centered on psychological characteristics of these sport experiences related to evaluative and affective components. In addition, this research has predominately relied on cross-sectional studies and attitudinal surveys to collect information with less emphasis on how various situational or environmental factors can influence attitudinal data patterns at the individual and group level. This special issue seeks to deepen our understanding of SCB by providing seven papers that demonstrate or validate findings using multiple studies or data collections

    Exploring the development of team identification.

    Get PDF
    The article discusses a study investigating the development of identification with sports teams, with particular focus given to the application of social identity theory and the psychological continuum model (PCM). The development of internal meaning attached to the team and external actions such as searching for team-related information and promoting the team to others is examined, and the influence of media on attitude formation is commented on. A review of previous literature on the topic is also provided

    Lifetime measurements in 184Pt and the shape coexistence picture

    Get PDF
    Lifetimes for levels in the yrast band of 184Pt have been measured up to spin 16+ using the recoil distance technique. The B(E2) values exhibit a marked increase in going from spin 2 to 10, consistent with a proposal that two bands of different deformations are mixing at low spin. This provides further support for shape coexistence occuring at low excitation energies in this region

    Search for a W' boson decaying to a bottom quark and a top quark in pp collisions at sqrt(s) = 7 TeV

    Get PDF
    Results are presented from a search for a W' boson using a dataset corresponding to 5.0 inverse femtobarns of integrated luminosity collected during 2011 by the CMS experiment at the LHC in pp collisions at sqrt(s)=7 TeV. The W' boson is modeled as a heavy W boson, but different scenarios for the couplings to fermions are considered, involving both left-handed and right-handed chiral projections of the fermions, as well as an arbitrary mixture of the two. The search is performed in the decay channel W' to t b, leading to a final state signature with a single lepton (e, mu), missing transverse energy, and jets, at least one of which is tagged as a b-jet. A W' boson that couples to fermions with the same coupling constant as the W, but to the right-handed rather than left-handed chiral projections, is excluded for masses below 1.85 TeV at the 95% confidence level. For the first time using LHC data, constraints on the W' gauge coupling for a set of left- and right-handed coupling combinations have been placed. These results represent a significant improvement over previously published limits.Comment: Submitted to Physics Letters B. Replaced with version publishe

    Search for the standard model Higgs boson decaying into two photons in pp collisions at sqrt(s)=7 TeV

    Get PDF
    A search for a Higgs boson decaying into two photons is described. The analysis is performed using a dataset recorded by the CMS experiment at the LHC from pp collisions at a centre-of-mass energy of 7 TeV, which corresponds to an integrated luminosity of 4.8 inverse femtobarns. Limits are set on the cross section of the standard model Higgs boson decaying to two photons. The expected exclusion limit at 95% confidence level is between 1.4 and 2.4 times the standard model cross section in the mass range between 110 and 150 GeV. The analysis of the data excludes, at 95% confidence level, the standard model Higgs boson decaying into two photons in the mass range 128 to 132 GeV. The largest excess of events above the expected standard model background is observed for a Higgs boson mass hypothesis of 124 GeV with a local significance of 3.1 sigma. The global significance of observing an excess with a local significance greater than 3.1 sigma anywhere in the search range 110-150 GeV is estimated to be 1.8 sigma. More data are required to ascertain the origin of this excess.Comment: Submitted to Physics Letters

    Measurement of the Lambda(b) cross section and the anti-Lambda(b) to Lambda(b) ratio with Lambda(b) to J/Psi Lambda decays in pp collisions at sqrt(s) = 7 TeV

    Get PDF
    The Lambda(b) differential production cross section and the cross section ratio anti-Lambda(b)/Lambda(b) are measured as functions of transverse momentum pt(Lambda(b)) and rapidity abs(y(Lambda(b))) in pp collisions at sqrt(s) = 7 TeV using data collected by the CMS experiment at the LHC. The measurements are based on Lambda(b) decays reconstructed in the exclusive final state J/Psi Lambda, with the subsequent decays J/Psi to an opposite-sign muon pair and Lambda to proton pion, using a data sample corresponding to an integrated luminosity of 1.9 inverse femtobarns. The product of the cross section times the branching ratio for Lambda(b) to J/Psi Lambda versus pt(Lambda(b)) falls faster than that of b mesons. The measured value of the cross section times the branching ratio for pt(Lambda(b)) > 10 GeV and abs(y(Lambda(b))) < 2.0 is 1.06 +/- 0.06 +/- 0.12 nb, and the integrated cross section ratio for anti-Lambda(b)/Lambda(b) is 1.02 +/- 0.07 +/- 0.09, where the uncertainties are statistical and systematic, respectively.Comment: Submitted to Physics Letters

    Search for new physics in events with opposite-sign leptons, jets, and missing transverse energy in pp collisions at sqrt(s) = 7 TeV

    Get PDF
    A search is presented for physics beyond the standard model (BSM) in final states with a pair of opposite-sign isolated leptons accompanied by jets and missing transverse energy. The search uses LHC data recorded at a center-of-mass energy sqrt(s) = 7 TeV with the CMS detector, corresponding to an integrated luminosity of approximately 5 inverse femtobarns. Two complementary search strategies are employed. The first probes models with a specific dilepton production mechanism that leads to a characteristic kinematic edge in the dilepton mass distribution. The second strategy probes models of dilepton production with heavy, colored objects that decay to final states including invisible particles, leading to very large hadronic activity and missing transverse energy. No evidence for an event yield in excess of the standard model expectations is found. Upper limits on the BSM contributions to the signal regions are deduced from the results, which are used to exclude a region of the parameter space of the constrained minimal supersymmetric extension of the standard model. Additional information related to detector efficiencies and response is provided to allow testing specific models of BSM physics not considered in this paper.Comment: Replaced with published version.
