EXAMINING THE INDONESIA AND MALAYSIA STUDENTATHLETES COPING STRATEGY IN SPORTS

The purpose of this paper is to compare the coping strategies among university student-athletes between Indonesia and Malaysia. A sample of 469 students athletes of Indonesia (226: female-69; male-157) and Malaysia (243: female-95; male-148) were randomly selected as the sample for this study. The age for Indonesia student-athletes (M=21.05, sd=2.31) and Malaysia student athletes (M=21.41, sd=2.50). The samples were selected from four major universities in Indonesia and Malaysia. Of the sample, 2.6% of Indonesian and 2.3% of Malaysian representing National team and 4.3% of Indonesian and 5.8% of Malaysian student-athletes representing state level during their study. However, 3.8% and 13.9% of Indonesian sample representing National and state during their high school year, respectively, 8.5% and 21.7% of the Malaysian sample representing National and state team during their high school year. The instrument used in this study was The Athletic Coping Skills Inventory (ACSI-28). Results show that there are significantly difference between Indonesia and Malaysia athletes in coping in adversity, concentration, mental preparation and goal setting, peaking under pressure and freedom from worries. Out of that, the Indonesian student-athletes score higher than Malaysian student-athletes in subthemes of freedom from worries. While, the others the Malaysia student-athletes score higher. Results were further discussed and recommended for future research

Penggunaan Narkotika dikalangan Olahragawan Malaysia

Penelitian ini bertujuan untuk mengenalpasti penggunaan narkotika dikalangan atlet mengikut kemahiran, iaitu yang mewakili peringkat Nasional (negara), negeri, daerah dan universiti. Selain itu, ia juga untuk melihat perbezaan penggunaan narkotika dikalangan atlet berdasarkan gender. Penelitian ini menggunakan sampel 111 atlet Malaysia (Negara = 31; Negeri = 35; Daerah = 19; Universitas = 26), yang dipilih secara random semasa pertandingan olahraga antara universitas. Manakala dari segi gender, atlet lelaki adalah 66 dan atlet perempuan adalah 45. Angket Penggunaan Narkotika (Drug Use Questionnaire) digunakan dalam penelitian ini untuk mengukur tahap penggunaan narkotika. Hasil penelitian menunjukkan tujuan utama penggunaan narkotika adalah untuk menang. Selain itu, penggunaan narkotika dikalangan atlet lelaki lebih tinggi daripada perempuan. Hasil penelitian juga menunjukkan narkotika lebih tinggi diguna oleh olahragawan yang mewakili peringkat Nasional (Negara). Ahli-ahli psikologi olahraga harus memainkan peranan penting untuk menggurangkan ketagihan penggunaan narkotika dengan memberi terapi yang berkesan. Pemerintah Malaysia harus melarang olahragawan yang menggunakan narkotika terlibat dalam pertandingan olahraga

Search for displaced vertices arising from decays of new heavy particles in 7 TeV pp collisions at ATLAS

We present the results of a search for new, heavy particles that decay at a significant distance from their production point into a final state containing charged hadrons in association with a high-momentum muon. The search is conducted in a pp-collision data sample with a center-of-mass energy of 7 TeV and an integrated luminosity of 33 pb^-1 collected in 2010 by the ATLAS detector operating at the Large Hadron Collider. Production of such particles is expected in various scenarios of physics beyond the standard model. We observe no signal and place limits on the production cross-section of supersymmetric particles in an R-parity-violating scenario as a function of the neutralino lifetime. Limits are presented for different squark and neutralino masses, enabling extension of the limits to a variety of other models.Comment: 8 pages plus author list (20 pages total), 8 figures, 1 table, final version to appear in Physics Letters

Measurement of the polarisation of W bosons produced with large transverse momentum in pp collisions at sqrt(s) = 7 TeV with the ATLAS experiment

This paper describes an analysis of the angular distribution of W->enu and W->munu decays, using data from pp collisions at sqrt(s) = 7 TeV recorded with the ATLAS detector at the LHC in 2010, corresponding to an integrated luminosity of about 35 pb^-1. Using the decay lepton transverse momentum and the missing transverse energy, the W decay angular distribution projected onto the transverse plane is obtained and analysed in terms of helicity fractions f0, fL and fR over two ranges of W transverse momentum (ptw): 35 < ptw < 50 GeV and ptw > 50 GeV. Good agreement is found with theoretical predictions. For ptw > 50 GeV, the values of f0 and fL-fR, averaged over charge and lepton flavour, are measured to be : f0 = 0.127 +/- 0.030 +/- 0.108 and fL-fR = 0.252 +/- 0.017 +/- 0.030, where the first uncertainties are statistical, and the second include all systematic effects.Comment: 19 pages plus author list (34 pages total), 9 figures, 11 tables, revised author list, matches European Journal of Physics C versio

Observation of a new chi_b state in radiative transitions to Upsilon(1S) and Upsilon(2S) at ATLAS

The chi_b(nP) quarkonium states are produced in proton-proton collisions at the Large Hadron Collider (LHC) at sqrt(s) = 7 TeV and recorded by the ATLAS detector. Using a data sample corresponding to an integrated luminosity of 4.4 fb^-1, these states are reconstructed through their radiative decays to Upsilon(1S,2S) with Upsilon->mu+mu-. In addition to the mass peaks corresponding to the decay modes chi_b(1P,2P)->Upsilon(1S)gamma, a new structure centered at a mass of 10.530+/-0.005 (stat.)+/-0.009 (syst.) GeV is also observed, in both the Upsilon(1S)gamma and Upsilon(2S)gamma decay modes. This is interpreted as the chi_b(3P) system.Comment: 5 pages plus author list (18 pages total), 2 figures, 1 table, corrected author list, matches final version in Physical Review Letter

Measurement of the inclusive isolated prompt photon cross-section in pp collisions at sqrt(s)= 7 TeV using 35 pb-1 of ATLAS data

A measurement of the differential cross-section for the inclusive production of isolated prompt photons in pp collisions at a center-of-mass energy sqrt(s) = 7 TeV is presented. The measurement covers the pseudorapidity ranges |eta|<1.37 and 1.52<=|eta|<2.37 in the transverse energy range 45<=E_T<400GeV. The results are based on an integrated luminosity of 35 pb-1, collected with the ATLAS detector at the LHC. The yields of the signal photons are measured using a data-driven technique, based on the observed distribution of the hadronic energy in a narrow cone around the photon candidate and the photon selection criteria. The results are compared with next-to-leading order perturbative QCD calculations and found to be in good agreement over four orders of magnitude in cross-section.Comment: 7 pages plus author list (18 pages total), 2 figures, 4 tables, final version published in Physics Letters

Reducing heterotic M-theory to five dimensional supergravity on a manifold with boundary

This paper constructs the reduction of heterotic $M$-theory in eleven dimensions to a supergravity model on a manifold with boundary in five dimensions using a Calabi-Yau three-fold. New results are presented for the boundary terms in the action and for the boundary conditions on the bulk fields. Some general features of dualisation on a manifold with boundary are used to explain the origin of some topological terms in the action. The effect of gaugino condensation on the fermion boundary conditions leads to a `twist' in the chirality of the gravitino which can provide an uplifting mechanism in the vacuum energy to cancel the cosmological constant after moduli stabilisation.Comment: 16 pages, RevTe

Measurement of D*+/- meson production in jets from pp collisions at sqrt(s) = 7 TeV with the ATLAS detector

This paper reports a measurement of D*+/- meson production in jets from proton-proton collisions at a center-of-mass energy of sqrt(s) = 7 TeV at the CERN Large Hadron Collider. The measurement is based on a data sample recorded with the ATLAS detector with an integrated luminosity of 0.30 pb^-1 for jets with transverse momentum between 25 and 70 GeV in the pseudorapidity range |eta| < 2.5. D*+/- mesons found in jets are fully reconstructed in the decay chain: D*+ -> D0pi+, D0 -> K-pi+, and its charge conjugate. The production rate is found to be N(D*+/-)/N(jet) = 0.025 +/- 0.001(stat.) +/- 0.004(syst.) for D*+/- mesons that carry a fraction z of the jet momentum in the range 0.3 < z < 1. Monte Carlo predictions fail to describe the data at small values of z, and this is most marked at low jet transverse momentum.Comment: 10 pages plus author list (22 pages total), 5 figures, 1 table, matches published version in Physical Review
