Cultural Differences And EMR Experiences: From The USA To The UAE And The UK
Electronic medical record (EMR) has gained increasing attention in the healthcare industry worldwide. Unfortunately, the adoption rate has been slower than what healthcare practitioners and IT professionals would expect. While various issues have recently been raised concerning hospitalsā and physiciansā EMR challenges, this research proposal specifically focuses on cultural differences in those healthcare organizationsā and practitionersā EMR experiences. More specifically, a four-layer cultural framework is proposed and discussed. In additional to traditionally perceived national and organizational cultures, the framework further distinguishes institutional and group cultures that might also interact with other cultural elements and healthcare organizationsā EMR experiences. Six organizations situated in three culturally contrasting countries with comparative external environments, business purposes, managerial values, IT services, and organizational sizes are selected as potential study sites. An interpretive case study is further proposed to help investigate complex interactions involved in this research phenomenon. With a more comprehensive perspective on cultural effects and emerging nature of EMR systems, empirical research contribution, upon the projectās completion, is thus anticipated
Contribution of Two-Boson-Exchange with Excitation to Parity-Violating Elastic Electron-Proton Scattering
We study the leading electroweak corrections in the precision measurement of
the strange form factors. Specifically, we calculate the two-boson-exchange
(TBE), two-photon-exchange (TPE) plus -exchange (E),
corrections with excitation to the parity-violating asymmetry of
the elastic electron-proton scattering. The interplay between nucleon and
contributions is found to depend strongly on the kinematics, as
begins as negligible at backward angles but becomes very large
and negative and dominant at forward angles, while always stays
positive and decreases monotonically with increasing . The total TBE
corrections to the extracted values of in recent
experiments of HAPPEX and G0 are, depending on kinematics, found to be large
and range between 13% to -75% but small in the case of A4 experiments.Comment: 5 pages, the result is correcte
Application of graphics processing units to search pipelines for gravitational waves from coalescing binaries of compact objects
We report a novel application of a graphics processing unit (GPU) for the purpose of accelerating the search pipelines for gravitational waves from coalescing binaries of compact objects. A speed-up of 16-fold in total has been achieved with an NVIDIA GeForce 8800 Ultra GPU card compared with one core of a 2.5 GHz Intel Q9300 central processing unit (CPU). We show that substantial improvements are possible and discuss the reduction in CPU count required for the detection of inspiral sources afforded by the use of GPUs
5GHz MMIC LNA Design Using Particle Swarm Optimization
This research presents an optimization study of a 5 GHz Monolithic Microwave Integrated Circuit (MMIC) design using Particle Swarm Optimization (PSO). MMIC Low Noise Amplifier (LNA) is a type of integrated circuit device used to capture signal operating in the microwave frequency. This project consists of two stages: implementation of PSO using MATLAB and simulation of MMIC design using Advanced Design System (ADS). PSO model that mimics the biological swarm behavior is developed to optimize the MMIC design variables in order to achieve the required circuit performance and specifications such as power gain, noise figure, drain current and circuit stability factor. Simulation results show that the proposed MMIC design fulfills the circuit stability factor and achieves a power gain of 19.73dB, a noise figure of 1.15 dB and a current of 0.0467A
Parametric spectral analysis: scale and shift
We introduce the paradigm of dilation and translation for use in the spectral
analysis of complex-valued univariate or multivariate data. The new procedure
stems from a search on how to solve ambiguity problems in this analysis, such
as aliasing because of too coarsely sampled data, or collisions in projected
data, which may be solved by a translation of the sampling locations.
In Section 2 both dilation and translation are first presented for the
classical one-dimensional exponential analysis. In the subsequent Sections 3--7
the paradigm is extended to more functions, among which the trigonometric
functions cosine, sine, the hyperbolic cosine and sine functions, the Chebyshev
and spread polynomials, the sinc, gamma and Gaussian function, and several
multivariate versions of all of the above.
Each of these function classes needs a tailored approach, making optimal use
of the properties of the base function used in the considered sparse
interpolation problem. With each of the extensions a structured linear matrix
pencil is associated, immediately leading to a computational scheme for the
spectral analysis, involving a generalized eigenvalue problem and several
structured linear systems.
In Section 8 we illustrate the new methods in several examples: fixed width
Gaussian distribution fitting, sparse cardinal sine or sinc interpolation, and
lacunary or supersparse Chebyshev polynomial interpolation
The Two-Boson-Exchange Correction to Parity-Violating Elastic Electron-Proton Scattering
We calculate the two-boson-exchange (TBE) corrections to the parity-violating
asymmetry of the elastic electron-proton scattering in a simple hadronic model
including the nucleon and the intermediate states. We find that
contribution is, in general, comparable with the
nucleon contribution and the current experimental measurements of
strange-quark effects in the proton neutral weak current. The total TBE
corrections to the current extracted values of
in recent experiments are found to lie in the
range of .Comment: 3 pages, 2 figs, 1 table, talk given at International Conference of
