Performance of local health services managers at district level is crucial to ensure that health services are of good quality and cater to the health needs of the population in the area. In many low- and middle-income countries, health services managers are poorly equipped with public health management capacities needed for planning and managing their local health system. In the south Indian Tu...

We treat equivariant completions of toric contraction morphisms as an application of the toric Mori theory. For this purpose, we generalize the toric Mori theory for non-Q-factorial toric varieties. So, our theory seems to be quite different from Reid’s original combinatorial toric Mori theory. We also explain various examples of non-Q-factorial contractions, which imply that the Q-factoriality...

Thu, Nov 16, 3:30pm Matt Szczesny (Boston Univ.) The Langlands program: from arithmetic to conformal field theory This will be a very elementary attempt to trace the sequence of analogies that lead from the Langlands program for global fields to the geometric formulation given by A. Beilinson and V. Drinfeld. I will attempt to explain the formulation of the latter in the language of conformal f...

The geometric Langlands program can be described in a natural way by compactifying on a Riemann surface C a twisted version of N = 4 super Yang-Mills theory in four dimensions. The key ingredients are electric-magnetic duality of gauge theory, mirror symmetry of sigma-models, branes, Wilson and ’t Hooft operators, and topological field theory. Seemingly esoteric notions of the geometric Langlan...

The score reliability of language performance tests has attracted increasing interest. Classical Test Theory cannot examine multiple sources of measurement error. Generalizability theory extends Classical Test Theory to provide a practical framework to identify and estimate multiple factors contributing to the total variance of measurement. Generalizability theory by using analysis of variance ...

Background:  Scene management in accidents reduces losses, speeds treatment, and facilitates immediate victim transfer. Learning the related skills through theory-based educational intervention makes this task possible. This study aimed to determine the effect of theory-based educational intervention on emergency medical personnel skills to manage the scene in chemical accidents. Materials and...

an azobenzene bridge was introduced into the lower (or smaller) rim of p-tert-butylcalix[8]arene to form 1,5-singly bridged calix[8]arene derivatives, respectively. bridged calix[8]arene of conformationally rigid wereisolated. the stability of the two structures of bridged calix[8]arenes have been compared.the study of organicstructure to form nanoporous structures is a well known in chemistry ...

Key Performance Indicators are used increasingly by health services, but their relevance and utility may be questionable. In this article, Program Theory is used to model the irreducible stages in the system of clinical care in Child and Adolescent Mental Health Services, define the major program operations in each of these stages, and specify the intermediate outcomes of each stage and the fin...

My Ph.D. dissertation describes an investigation of scientific reasoning from a computational perspective (Karp 1989).1 The investigation focuses on a program of research in molecular biology that culminated in the discovery of a new mechanism of bacterial gene regulation called attenuation. In the first phase of my work, I performed a historical study of this program of biological research in ...
