- The purpose of this study is to compare the capacity or potential of governments inEast and Southeast Asia in their utilization of E-government as an instrument to deliverpublic services to their citizens. The principal component analysis methodology is used tocompute the E-government index. The index is used as a benchmark to compare theperformance of developing and newly industrialized economies in delivery of publicservices. The overall index is compromised of three main components: ICTinfrastructure, development information and finances indices. The E-government indexlevel shows the capacity of each country’s governments to deliver public services. Theresult is useful for identifying the weaknesses and strengths in their service provision. Anattempt is made to suggest alternative approaches to achieve the goals and progresstowards an advanced E-government-based service provision that enhances equality inopportunities. ©2010 by Nova Science Publishers, Inc.

- This chapter offers a comprehensive summary of applications of advanced diffusion encoding methods in MRI within a narrowly defined area of in vivo human measurements with imaging read-out and voxel-by-voxel data analysis. The list of methods comprises tensor-valued encoding to investigate cell densities, shapes, and orientations in heterogeneous tissues, time/frequency-dependent encoding for estimating structural length scales, adjustable velocity-encoding to monitor flow in the microcapillary network, double encoding with varying mixing times to assess diffusional exchange between distinct tissue microenvironments and across cell membranes, and relaxation-diffusion correlation to resolve and separately characterize tissue microenvironments in terms of their local chemical composition and microstructure. The shown examples include proof-of-concept measurements on healthy volunteers, pilot investigations of pathologies, and clinical research involving 10-100 subjects. Studied organs include brain, breast, prostate, liver, kidney, placenta, muscle, and peripheral nerve, with examples of pathologies from tumors, schizophrenia, multiple sclerosis, stroke, neurocysticercosis, pre-eclampsia, and chronic exertional compartment syndrome.
