A DISTRIBUTIONAL ANALYSIS OF THE COSTS OF FOODBORNE ILLNESS: WHO ULTIMATELY PAYS?

This paper traces the economic impact of the costs of foodborne illness on the U.S. economy using a Social Accounting Matrix (SAM) framework. Previous estimates of the costs of seven foodborne pathogens are disaggregated by type, and distributed across the population using data from the National Health Interview Survey. Initial income losses resulting from premature death cause a decrease in economic activity. Medical costs, in contrast, result in economic growth, though this growth does not outweigh the total costs of premature death. A SAM accounting of how the costs of illness are diffused through the economy provides useful information for policy makers.Cost of illness, Foodborne illness, Social Accounting Matrix, Food Consumption/Nutrition/Food Safety,

Large Parameter Cases of the Gauss Hypergeometric Function

We consider the asymptotic behaviour of the Gauss hypergeometric function when several of the parameters a, b, c are large. We indicate which cases are of interest for orthogonal polynomials (Jacobi, but also Krawtchouk, Meixner, etc.), which results are already available and which cases need more attention. We also consider a few examples of 3F2-functions of unit argument, to explain which difficulties arise in these cases, when standard integrals or differential equations are not available.Comment: 21 pages, 4 figure

Implications of conservation equations for the determination of absolute velocities

The consequences of assuming that density is conserved in the problem of determining absolute velocities are investigated. Two questions are considered: (i) the constraints that the density must satisfy to be compatible with the assumed geostrophic and hydrostatic dynamics and (ii) whether and to what extent the indeterminacy in this dynamics is removed by this additional assumption

PERENCANAAN STRATEGIS SISTEM INFORMASI PADA PT. ANDIKA PRATAMA SATYA DENGAN METODE WARD AND PEPPARD

PT. Andika Pratama Satya merupakan perusahaan distribusi agen suku cadang mesin alat-alat berat. PT. Andika Pratama Satya memiliki beberapa SI/TI tetapi belum memiliki perencanaan strategis SI/TI serta implementasi SI/TI yang belum terintegrasi satu dengan lainnya sehingga proses bisnis tidak berjalan dengan maksimal. Hal ini menjadikan PT. Andika Pratama Satya membutuhkan perencanaan strategis SI/TI untuk menunjang proses bisnisnya. Penelitian ini menggunakan metode Ward and Peppard karena berfokus pada pembangunan rencana strategis TI yang terintegrasi dengan bisnis organisasi. Penelitian ini mengidentifikasi kondisi lingkungan internal dan eksternal bisnis dan SI/TI perusahaan menggunakan alat analisis meliputi SWOT, Value Chain, Balanced Scorecard, Porter’s Five Forces, dan McFarlan Strategic Grid. Hasil penelitian ini berupa penyusunan strategi SI yaitu SI HRGA, SI Keuangan, SI Gudang, E-Faktur, website, E-mail, media sosial, E-commerce, dan E-CRM. Penyusunan strategi manajemen SI/TI yaitu usulan penambahan divisi staf IT, pembagian tanggung jawab pengelolaan aplikasi yang diusulkan, serta penambahan pegawai baru. Penyusunan strategi TI yaitu usulan pemanfaatan cloud computing, otomasi proses bisnis, dan integrasi antar sistem informasi setiap divisi pada perusahaan. Rancangan roadmap pengembangan aplikasi dibuat menjadi skala prioritas yang akan dilaksanakan selama empat semester kedepan

Tunneling in two dimensional QCD

The spectral density for two dimensional continuum QCD has a non-analytic behavior for a critical area. Apparently this is not reflected in the Wilson loops. However, we show that the existence of a critical area is encoded in the winding Wilson loops: Although there is no non-analyticity or phase transition in these Wilson loops, the dynamics of these loops consists of two smoothly connected domains separated by the critical area, one domain with a confining behavior for large winding Wilson loops, and one (below the critical size) where the string tension disappears. We show that this can be interpreted in terms of a simple tunneling process between an ordered and a disordered state. In view of recent results by Narayanan and Neuberger this tunneling may also be relevant for four dimensional QCD.Comment: 10 pages. Clarifying remarks have been adde

Enzyme kinetics for a two-step enzymic reaction with comparable initial enzyme-substrate ratios

We extend the validity of the quasi-steady state assumption for a model double intermediate enzyme-substrate reaction to include the case where the ratio of initial enzyme to substrate concentration is not necessarily small. Simple analytical solutions are obtained when the reaction rates and the initial substrate concentration satisfy a certain condition. These analytical solutions compare favourably with numerical solutions of the full system of differential equations describing the reaction. Experimental methods are suggested which might permit the application of the quasi-steady state assumption to reactions where it may not have been obviously applicable before
