    Causes, Effects, and Remedies in Conflict Management

    Full text link
    While workplace conflicts have been widely studied in the literature, this researchprovides a holistic view of the causes and effects of such, and how managers or amanagement can resolve the conflicts among their teams and organization througha detailed, multidimensional framework carried out on one of the biggest textilefirms of Pakistan. With an initial sample of 145 respondents, 37 questionnaireswere dropped because of invalid and incomplete answers; therefore, the studywas carried out on 108 respondents. Conflicts are a part of human nature, butmanagement should play an important role in dealing with these issues, as therecan be enormous chances of conflicts due to a diverse workforce. Conflict alsoresults in poor work performance and low productivity; therefore, it’s suggestedto create teams or groups which may encourage a competitive culture in theorganization. Additionally, a few remedies are identified, which may resolve someissues; managers must look at those techniques for a better culture.&nbsp

    SIMPLE: Stable Increased-throughput Multi-hop Protocol for Link Efficiency in Wireless Body Area Networks

    Full text link
    In this work, we propose a reliable, power efficient and high throughput routing protocol for Wireless Body Area Networks (WBANs). We use multi-hop topology to achieve minimum energy consumption and longer network lifetime. We propose a cost function to select parent node or forwarder. Proposed cost function selects a parent node which has high residual energy and minimum distance to sink. Residual energy parameter balances the energy consumption among the sensor nodes while distance parameter ensures successful packet delivery to sink. Simulation results show that our proposed protocol maximize the network stability period and nodes stay alive for longer period. Longer stability period contributes high packet delivery to sink which is major interest for continuous patient monitoring.Comment: IEEE 8th International Conference on Broadband and Wireless Computing, Communication and Applications (BWCCA'13), Compiegne, Franc

    Two flavors of dynamical quarks on anisotropic lattices

    We report on our study of two-flavor full QCD on anisotropic lattices using O(a)O(a)-improved Wilson quarks coupled with an RG-improved glue. The bare gauge and quark anisotropies corresponding to the renormalized anisotropy ξ=as/at=2\xi=a_s/a_t = 2 are determined as functions of β\beta and κ\kappa, which covers the region of spatial lattice spacings as≈0.28a_s\approx 0.28--0.16 fm and mPS/mV≈0.6m_{PS}/m_V\approx 0.6--0.9. The calibrations of the bare anisotropies are performed with the Wilson loop and the meson dispersion relation at 4 lattice cutoffs and 5--6 quark masses. Using the calibration results we calculate the meson mass spectrum and the Sommer scale r0r_0. We confirm that the values of r0r_0 calculated for the calibration using pseudo scalar and vector meson energy momentum dispersion relation coincide in the continuum limit within errors. This work serves to lay ground toward studies of heavy quark systems and thermodynamics of QCD including the extraction of the equation of state in the continuum limit using Wilson-type quark actions.Comment: 16 pages, 23 figures, Version accepted for publication in Physical Review

    Perturbative renormalization factors in domain-wall QCD with improved gauge actions

    Get PDF
    We evaluate renormalization factors of the domain-wall fermion system with various improved gauge actions at one loop level. The renormalization factors are calculated for quark wave function, quark mass, bilinear quark operators, three- and four-quark operators in modified minimal subtraction (MS-bar) scheme with the dimensional reduction(DRED) as well as the naive dimensional regularization(NDR). We also present detailed results in the mean field improved perturbation theory.Comment: 44 page

    The Lattice Λ\Lambda Parameter in Domain Wall QCD

    Full text link
    We evaluate the ratio of the scale parameter Λ\Lambda in domain wall QCD to the one in the continuum theory at one loop level incorporating the effect of massless quarks. We show that the Pauli-Villars regulator is required to subtract the unphysical massive fermion modes which emerge in the fermion loop contributions to the gluon self energy. Detailed results are presented as a function of the domain wall height MM.Comment: 16 pages, 1 figure as eps-file, some references adde

    Renormalization group improved action on anisotropic lattices

    Get PDF
    We study a block spin transformation in the SU(3) lattice gauge theory on anisotropic lattices to obtain Iwasaki's renormalization group improved action for anisotropic cases. For the class of actions with plaquette and 1×21\times2 rectangular terms, we determine the improvement parameters as functions of the anisotropy ξ=as/at\xi= a_s/a_t. We find that the program of improvement works well also on anisotropic lattices. From a study of an indicator which estimates the distance to the renormalized trajectory, we show that, for the range of the anisotropy ξ≈1\xi \approx 1--4, the coupling parameters previously determined for isotropic lattices improve the theory considerably.Comment: 15 pages, 10 figure

    Non-perturbative renormalization in domain-wall QCD by Schr\"odinger functional scheme

    Get PDF
    We formulate and numerically test the Schr\"odinger functional scheme for domain-wall QCD. We then apply it to a non-perturbative calculation of the renormalization factors for vector and axial-vector currents in quenched domain-wall QCD with plaquette and renormalization group improved gauge actions at a−1≃2a^{-1}\simeq 2 GeV.Comment: Lattice2001(improvement), LaTex(espcrc2.sty), 3 pages, 5 eps figure

    Flavor Singlet Meson Mass in the Continuum Limit in Two-Flavor Lattice QCD

    Get PDF
    We present results for the mass of the eta-prime meson in the continuum limit for two-flavor lattice QCD, calculated on the CP-PACS computer, using a renormalization-group improved gauge action, and Sheikholeslami and Wohlert's fermion action with tadpole-improved csw. Correlation functions are measured at three values of the coupling constant beta corresponding to the lattice spacing a approx. 0.22, 0.16, 0.11 fm and for four values of the quark mass parameter kappa corresponding to mpi over mrho approx. 0.8, 0.75, 0.7 and 0.6. For each beta, kappa pair, 400-800 gauge configurations are used. The two-loop diagrams are evaluated using a noisy source method. We calculate eta-prime propagators using local sources, and find that excited state contributions are much reduced by smearing. A full analysis for the smeared propagators gives metaprime=0.960(87)+0.036-0.248 GeV, in the continuum limit, where the second error represents the systematic uncertainty coming from varying the functional form for chiral and continuum extrapolations.Comment: 9 pages, 19 figures, 4 table
