    Get PDF
    The purpose of this proposal is to develop and implement a concentration in Supply Chain Management in the existing traditional MBA program effective fall 2012. Houston is the hub for many multinational oil and energy companies, large healthcare systems, wholesale/retail businesses, engineering and construction companies, and is a major city along the transportation artery of NAFTA. The program is designed to provide SCM expertise to students in the existing traditional MBA program. The environment for this proposal is the School of Business at Texas Southern University, Houston, Texas 77004

    Technological Change, Automation and Employment: A Short Review of Theory and Evidence

    Get PDF
    A selective survey of recent papers in the area of technological change, automation and employment is presented. The objective is to convey analytical ideas and the empirical evidence that have informed studies in this area of contemporary policy relevance. Automation occurs when a machine does work that might previously have been done by a person. How robots and automation affect the availability of jobs for labor force? There are very few emerging studies that address the issue with detailed data on robots usage and employment in different sectors of the economy. Based on our review of available studies and empirical evidence the following statements can be made: (1) Increasing automation and robots adoption do not seem to cause loss of employment in the aggregate (2) Low skilled workers in routine jobs are more likely to suffer job losses. (3) There will be demand for new types of skilled workers or new specializations within occupations. Prospective automation intensifies the degree of uncertainty in labor markets across countries

    A Dynamic Renormalization Group Study of Active Nematics

    Full text link
    We carry out a systematic construction of the coarse-grained dynamical equation of motion for the orientational order parameter for a two-dimensional active nematic, that is a nonequilibrium steady state with uniaxial, apolar orientational order. Using the dynamical renormalization group, we show that the leading nonlinearities in this equation are marginally \textit{irrelevant}. We discover a special limit of parameters in which the equation of motion for the angle field of bears a close relation to the 2d stochastic Burgers equation. We find nevertheless that, unlike for the Burgers problem, the nonlinearity is marginally irrelevant even in this special limit, as a result of of a hidden fluctuation-dissipation relation. 2d active nematics therefore have quasi-long-range order, just like their equilibrium counterpartsComment: 31 pages 6 figure

    The exponential map for representations of Up,q(gl(2))U_{p,q}(gl(2))

    Full text link
    For the quantum group GLp,q(2)GL_{p,q}(2) and the corresponding quantum algebra Up,q(gl(2))U_{p,q}(gl(2)) Fronsdal and Galindo explicitly constructed the so-called universal TT-matrix. In a previous paper we showed how this universal TT-matrix can be used to exponentiate representations from the quantum algebra to get representations (left comodules) for the quantum group. Here, further properties of the universal TT-matrix are illustrated. In particular, it is shown how to obtain comodules of the quantum algebra by exponentiating modules of the quantum group. Also the relation with the universal RR-matrix is discussed.Comment: LaTeX-file, 7 pages.

    The use of hydrothermal methods in the synthesis of novel open-framework materials

    Get PDF
    The preparation of inorganic compounds, exhibiting open-framework structures, by hydrothermal methods has been presented. To illustrate the efficacy of this approach, few select examples encompassing a wide variety and diversity in the structures have been provided. In all the cases, good quality single crystals were obtained, which were used for the elucidation of the structure. In the first example, simple inorganic network compounds based on phosphite and arsenate are described. In the second example, inorganic-organic hybrid compounds involving phosphite/arsenate along with oxalate units are presented. In the third example, new coordination polymers with interesting structures are given. The examples presented are representative of the type and variety of compounds one can prepare by careful choice of the reaction conditions

    The marketing firm and co‐creation: The case of co‐creation by LEGO

    Get PDF
    This article discusses the marketer and customer co‐creation process within the context of bilateral contingencies. Bilateral contingencies occur when the marketers' behavior is reinforced (and/or punished) by the customers' behavior, whereas the behavior of the customers is reinforced (and/or punished) by the marketers' actions. Using the example of the LEGO community, we discuss how the marketers in the organization can respond to behaviors resulting from co‐creational customer– customer exchanges. This paper fills the knowledge gap by presenting a behavior analysis framework (theory of the marketing firm) for the empirical measurement of the co‐creation process.The marketing firm and co‐creation: The case of co‐creation by LEGOacceptedVersio

    EVALUATION OF SOLAR PHOTOVOLTAIC WATER PUMPING SYSTEM AND IMPROVING ITS EFFICIENCY FOR DEVELOPING AN ENERGY STORAGE DEVICE

    Get PDF
    An electricity demand in India is now at an all-time high. Agriculture accounts for 21.5 percent of total electricity use; according to sectoral demand patterns. Technology is becoming increasingly popular. PV cells are utilized to power electrical equipment because of their high energy output. Solar energy is a clean and inexpensive energy source. Solar powered water pumping is an important technology for conserving vital resources such as water and electricity. This experiment is to calculate the efficiency of solar pump and panel. It is evaluated by calculating the input and output energy of the pump and panel. By comparing the efficiencies of pump and panel we can be able to estimate the amount of loss of energy. For conserving the energy, we can also install battery and charge controller for the use of pump in dark without solar energy. It conserves energy even while the pump is working. At the time of 2-3pm the efficiency of solar panel is about 55-60% and for the pump is 50-55%. By installing the storage device, we can save 2-5% of the energy wastage. This proves to be a better implementation for conserving the energy and the use of pump at any time. View Article DOI: 10.47856/ijaast.2022.v09i08.00

    Singular Scaling Functions in Clustering Phenomena

    Full text link
    We study clustering in a stochastic system of particles sliding down a fluctuating surface in one and two dimensions. In steady state, the density-density correlation function is a scaling function of separation and system size.This scaling function is singular for small argument -- it exhibits a cusp singularity for particles with mutual exclusion, and a divergence for noninteracting particles. The steady state is characterized by giant fluctuations which do not damp down in the thermodynamic limit. The autocorrelation function is a singular scaling function of time and system size. The scaling properties are surprisingly similar to those for particles moving in a quenched disordered environment that results if the surface is frozen.Comment: 8 pages, 3 figures, Invited talk delivered at Statphys 23, Genova, July 200
