    The purpose of this study was to examine the relationship between leadership style and performance of athletes and coaches in Malaysia. One hundred and thirty seven athletes and 47 coaches from 12 sports participated in the study. Leadership Scale for Sport (LSS) questionnaire was utilized to assessed athletes’ preference, perceived and coaches’ perception of their own leadership style. Result showed athletes most preferred coaching styles were training and instruction followed by democratic, positive feedback and social support. Autocratic behaviour was the least preferred. However coaches’ self-evaluation showed majority were keen on autocratic leadership style. Overall, the results of the study proposed that coaches should emphasis on training and instruction and less autocratic leadership style. Coaches also need to practise more positive feedback which proven can enhance athletes performance.Key word: Leadership style, sports performance, coach, athletes

    A consumer ethnocentrism model of foreign grocery retail store patronage in Beijing : do extrinsic cues and shopping orientation matter?

    The most widely used marketing concept to explain consumers' reluctance to patronise foreign retail stores and to purchase imported products is consumer ethnocentrism (CET). To date, however, research has mostly concentrated on the antecedents and consequences of CET, whilst little is known about variables that may offset the impact of CET. This study represents the first step in addressing this gap by examining shopping orientation, specifically utilitarian value, as a moderator of the relationship between CET and the consumers' willingness to shop in foreign grocery retail stores (WTS). Other important research gaps addressed in this study are context specific (i.e., consumers and grocery retailers in China), which includes an investigation of the impact of country-of-origin cue, store brand cue, CET and shopping orientation on WTS, the causal relationships between CET, WTS and customer loyalty (i.e., attitudinal and behavioural loyalty) as well as between shopping orientation and customer loyalty, and the robustness of the CETSCALE (i.e., CET measurement instrument) in relation to socially desirable response bias. Building on an extensive literature review, a consumer ethnocentrism model of foreign grocery retail store patronage was conceptualised and examined for its theoretical applicability in Beijing via an initial qualitative study. The conclusive quantitative phase was store-intercept surveys conducted in four Beijing hypermarkets owned by two established domestic and foreign grocery retailers in China; this achieved a total sample of 500 questionnaires. Rigorous statistical assessment of the collected questionnaires was undertaken, where the raw data was verified for data entry accuracy, missing values in the raw datasets were resolved via the multiple imputation method, and the multiple imputed datasets were assessed for outliers and non-normality. The conceptual model was then tested using Structural Equation Modelling (SEM). Based on conventional SEM procedures, the main results revealed that utilitarian value was a significant moderator of the relationship between CET and WTS, whilst the country-of- origin cue and store brand cue returned non-significant effects. In addition, store origin was a significant moderator of the relationship between WTS and loyalty intention towards foreign grocery retailers, i. e., this relationship was positively related for Beijing consumers who shop in foreign grocery stores but non-significant for those who shop in domestic grocery stores. The findings, theoretical and managerial implications, limitations and directions for future research are discussed.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

    Hamiltonian and Linear-Space Structure for Damped Oscillators: I. General Theory

    Full text link
    The phase space of NN damped linear oscillators is endowed with a bilinear map under which the evolution operator is symmetric. This analog of self-adjointness allows properties familiar from conservative systems to be recovered, e.g., eigenvectors are "orthogonal" under the bilinear map and obey sum rules, initial-value problems are readily solved and perturbation theory applies to the_complex_ eigenvalues. These concepts are conveniently represented in a biorthogonal basis.Comment: REVTeX4, 10pp., 1 PS figure.

    Group B streptococcus cystitis presenting in a diabetic patient with a massive abdominopelvic abscess: a case report

    Get PDF
    INTRODUCTION: Streptococcus agalactiae or group B streptococcus is a Gram-positive pathogen that is typically associated with neonatal disease and infection in pregnant women. Group B streptococcus also causes invasive infections in non-pregnant adults including urinary tract infections. The spectrum of urinary tract infections caused by group B streptococcus includes cystitis, pyelonephritis, urosepsis and asymptomatic bacteriuria, which is particularly common among elderly individuals. A rare form of invasive group B streptococcus infection in adults is secondary abscess. Here, we present the first reported case of a patient who developed an unusual, massive abdominopelvic abscess secondary to acute group B streptococcus urinary tract infection. CASE PRESENTATION: A 46-year-old African-American woman presented to the University Emergency Department complaining of urinary tract infection symptoms and severe abdominal pain. Diagnostic imaging by transvaginal ultrasound and computed tomography revealed a massive peripherally-enhancing, low-attenuating fluid collection within her pelvis. The patient’s abdominopelvic abscess was drained by ultrasound-guided drainage and this yielded a septic aspirate that was culture positive for abundant S. agalactiae. A recent history of urinary tract infection symptoms in the patient suggested that her abscess developed secondary to cystitis. Complete resolution of the abscess as a favorable outcome was achieved in this case following surgical drainage and appropriate antimicrobial therapy. CONCLUSION: Acute bacterial urinary tract infection leading to an abdominopelvic abscess has not previously been reported in the literature. This case report defines a new disease etiology associated with acute streptococcal cystitis and it will be of interest in cases of urinary tract infections where there is an association with abdominal and/or pelvic pain. A brief review of the literature on unusual secondary abscesses due to group B streptococcus is provided alongside this case to highlight the clinical significance and prognoses of these rare infections. Finally, this case emphasizes the requirement to distinguish unusual etiologies of pyogenic abscesses in order to guide successful clinical management and to treat patients with antibiotics active against the causal organism

    Eigenvector Expansion and Petermann Factor for Ohmically Damped Oscillators

    Full text link
    Correlation functions C(t)C(t) \sim in ohmically damped systems such as coupled harmonic oscillators or optical resonators can be expressed as a single sum over modes jj (which are not power-orthogonal), with each term multiplied by the Petermann factor (PF) CjC_j, leading to "excess noise" when Cj>1|C_j| > 1. It is shown that Cj>1|C_j| > 1 is common rather than exceptional, that Cj|C_j| can be large even for weak damping, and that the PF appears in other processes as well: for example, a time-independent perturbation \sim\ep leads to a frequency shift \sim \ep C_j. The coalescence of JJ (>1>1) eigenvectors gives rise to a critical point, which exhibits "giant excess noise" (CjC_j \to \infty). At critical points, the divergent parts of JJ contributions to C(t)C(t) cancel, while time-independent perturbations lead to non-analytic shifts \sim \ep^{1/J}.Comment: REVTeX4, 14 pages, 4 figures. v2: final, 20 single-col. pages, 2 figures.

    A highly flexible electrochemical supercapacitor electrode was developed with a novel metal oxide-reinforced nanofiber electrode by utilizing a solution-based electrospinning technique. The facile fabrication steps involved the introduction of metal precursors into a polymeric solution, which was subjected to an in situ electrospinning process. The electrospun polymeric web with metallic ingredients was then subjected to an oxidative stabilization process that induced the formation of metal oxide nanoparticles within the polymer structure. Finally, the metal oxide nanoparticles incorporated with nanofibers were obtained using a carbonization process, thus converting the polymer backbones into a carbon-rich conductive nanofiber structure. The fabricated nanofibers were decorated and implanted with metal oxide nanoparticles that had a surface-decorated structure morphology due to the solubility of the precursors in the reaction solution. The electrochemical performance of the fabricated metal oxide reinforced with nanofiber electrodes was investigated as an electrochemical system, and the novel morphology significantly improved the specific capacitance compared to a pristine carbon nanofiber membrane. As a result of the uniform dispersion of metal oxide nanoparticles throughout the surface of the nanofibers, the overall capacitive behavior of the membrane was enhanced. Furthermore, a fabricated free-standing flexible device that utilized the optimized nanofiber electrode demonstrated high stability even after it was subjected to various bending operations and curvatures. These promising results showed the potential applications of these lightweight, conductive nanofiber electrodes in flexible and versatile electronic devices

    Get PDF
    One of the challenges to maintain an agenda for universal coverage and equitable health system is to develop effective structuring and management of health financing. Global experiences with different systems of health financing suggests that a strong public role in health financing is essential for health systems to protect the poor and health systems with the strongest state role are likely the more equitable and achieve better aggregate health outcomes. Using Malaysia as a case study, this paper seeks to evaluate the progress and capacity of a middle income country in terms of health financing for universal coverage, and also to highlight some of the key underlying health systems challenges
