E-Government:: A Comparative Study of the G2C Online Services Progress Using Multi-Criteria Analysis

Governments across the European Union (EU) face the challenge of responding to public demand for more responsive, efficient and effective services. E-Government based on the principle of providing services via internet to citizens and companies. The rapid growth of electronic government gave the EU the ability to correspond more effectively to the needs of citizens and provide more valuable services. In this paper the authors analyze the web based services that have been developed by EU member states. A comparative measurement of the progress of online services delivery is presented using a Multi-criteria INteractive Ordinal Regression Analysis (MINORA) system. The paper demonstrates the importance of Multicriteria Analysis and the use of reliable methods that allowed the development of a function of total utility dynamically modified depending on the evolution of e-government services. © 2010, IGI Global.

Surface electromyography using dry polymeric electrodes.

Conventional wet Ag/AgCl electrodes are widely used in electrocardiography, electromyography (EMG), and electroencephalography (EEG) and are considered the gold standard for biopotential measurements. However, these electrodes require substantial skin preparation, are single use, and cannot be used for continuous monitoring (>24 h). For these reasons, dry electrodes are preferable during surface electromyography (sEMG) due to their convenience, durability, and longevity. Dry conductive elastomers (CEs) combine conductivity, flexibility, and stretchability. In this study, CEs combining poly(3,4-ehtylenedioxythiophene):polystyrenesulfonate (PEDOT:PSS) in polyurethane are explored as dry, skin contacting EMG electrodes. This study compares these CE electrodes to commercial wet Ag/AgCl electrodes in five subjects, classifying four movements: open hand, fist, wrist extension, and wrist flexion. Classification accuracy is tested using a backpropagation artificial neural network. The control Ag/AgCl electrodes have a 98.7% classification accuracy, while the dry conductive elastomer electrodes have a classification accuracy of 99.5%. As a conclusion, PEDOT based dry CEs were shown to successfully function as on-skin electrodes for EMG recording, matching the performance of Ag/AgCl electrodes, while addressing the need for minimal skin prep, no gel, and wearable technology

Reasoning maps for decision aid: an integrated approach for problem-structuring and multi-criteria evaluation

This paper proposes a tool for multi-criteria decision aid to be referred to as a Reasoning Map. It is motivated by a desire to provide an integrated approach to problem structuring and evaluation, and in particular, to make the transition between these two processes a natural and seamless progression. The approach has two phases. In the first one, the building of a Reasoning Map supports problem structuring, capturing a decision maker's reasoning as a network of means and ends concepts. In the second phase, this map is enhanced, employing a user-defined qualitative scale to measure both performances of decision options and strengths of influence for each means–end link. This latter phase supports the decision maker in evaluating the positive and negative impacts of an action through synthesis of the qualitative information. A case study, which investigates the use of the method in practice, is also presented
