    The Malaysian public sector has undergone various transformations since the Independence. From its custodial role in the newly independent country, the public sector had changed and taken an active role in the country’s economic development. However, since 1980s onwards, the philosophy and techniques of New Public Management (NPM) have been implemented in Malaysia.This again transformed the public sector from being an engine of economic growth to become a facilitator to the private sector and service provider to the public. In line with NPM’s underlying belief of the superiority of businesslike practices, various contemporary management practices and philosophy were implemented in the Malaysian public sector. The implantation of private sector practices in the public sector was enhanced with the introduction a performance measurement system which utilises the use of key performance indicators in 2005. Thus, the purpose of this paper is to examine and analyse the current improvement programme within the wider public sector reform programmes in Malaysia. The issues and consequences of using key performance indicators in the public sector are discussed. To understand further the reasons and the push for reform, contextual descriptions of the various phases of public sector reform in Malaysia are also discussed in this paper

    Maxon and roton measurements in nanoconfined 4^4He

    We investigate the behavior of the collective excitations of adsorbed 4^4He in an ordered hexagonal mesopore, examining the crossover from a thin film to a confined fluid. Here we present the inelastic scattering results as a function of filling at constant temperature. We find a monotonic transition of the maxon excitation as a function of filling. This has been interpreted as corresponding to an increasing density of the adsorbed helium, which approaches the bulk value as filling increases. The roton minimum exhibits a more complicated behavior that does not monotonically approach bulk values as filling increases. The full pore scattering resembles the bulk liquid accompanied by a layer mode. The maxon and roton scattering, taken together, at intermediate fillings does not correspond to a single bulk liquid dispersion at negative, low, or high pressure.Comment: 9 pages, 10 figure

    The Quantum McKay Correspondence for polyhedral singularities

    Let G be a polyhedral group, namely a finite subgroup of SO(3). Nakamura's G-Hilbert scheme provides a preferred Calabi-Yau resolution Y of the polyhedral singularity C^3/G. The classical McKay correspondence describes the classical geometry of Y in terms of the representation theory of G. In this paper we describe the quantum geometry of Y in terms of R, an ADE root system associated to G. Namely, we give an explicit formula for the Gromov-Witten partition function of Y as a product over the positive roots of R. In terms of counts of BPS states (Gopakumar-Vafa invariants), our result can be stated as a correspondence: each positive root of R corresponds to one half of a genus zero BPS state. As an application, we use the crepant resolution conjecture to provide a full prediction for the orbifold Gromov-Witten invariants of [C^3/G].Comment: Introduction rewritten. Issue regarding non-uniqueness of conifold resolution clarified. Version to appear in Inventione

    “Two Wars and the Long Twentieth Century:” A Response

    Full text link
    Drew Gilpin Faust, president of Harvard University and renowned historian of the American Civil War, authored an article in the New Yorker recently entitled “Two Wars and the Long Twentieth Century.” Taken primarily from her remarks in the Rede Lecture delivered at the University of Cambridge earlier in 2015, Faust’s article takes advantage of the proximity of the anniversaries of the First World War and the American Civil War to advocate for a dialogue of greater continuity between the two conflicts.

    Rich Nations, Poor Nations: How much can multiple equilibria explain?

    Get PDF
    The idea that income differences between rich and poor nations arise through multiple equilibria or 'poverty traps' is as intuitive as it is difficult to verify. In this paper, we explore the empirical relevance of such models. We calibrate a simple two sector model for 127 countries, and use the results to analyze the international prevalence of poverty traps and their consequences for productivity. We also examine the possible effects of multiplicity on the world distribution of income, and identify events in the data that may correspond to equilibrium switching.
