The MoU – Mouse or Momentous? An Update and Evaluation of the EC Memorandum of Understanding

Over 200 institutions have recently signed the European Commission's Multi-Media Access to Europe's Cultural Heritage: A Memorandum of Understanding and European Charter, an initiative launched by Directorate Generales (DG's), DG XIII (Telematics, Information Market and Exploitation of Research) and DG X (Information, Communication, Culture and Audio-Visual Media). This report summarises the goals of the Memorandum and offers thoughts on its implications and potential.

State Policies for Standardized Achievement Testing of Limited English Proficient Students

To what extent have state departments of education developed policies for testing limited English proficiency students with standardized achievement tests? What are some of the relationships between the development of these testing policies and the establishment of bilingual education in the states? What work still lies ahead in standardized achievement testing of limited English proficient students?     

Experimental verification of Faradaic charging in ac electrokinetics

This paper investigates the phenomenon of Faradaic charging in ac electrokinetics. Faradaic reactions were suggested as a key effect responsible for the reversal of pumping direction in ac micropumps. However, this hypothesis has yet to be proven convincingly and directly. Here we present an ion detection strategy to determine the production of ions through Faradaic hydrolytic reactions originating from direct application of voltage to electrolytic solutions during ac electrokinetics. Experiments were performed with symmetrical planar electrodes aligned along a microfluidic channel. Fluorescein, a pH-dependent dye, was employed as the pH indicator for the detection of ion production. Images were captured for analysis at various voltage levels. From analyzing the fluorescence intensity and its distribution, it can be concluded that the production of ions from hydrolytic reactions takes place and increases with the ac voltage. The coefficient of deviation indicates a significant enhancement at ac voltage above 11 V_pp. Lastly, we demonstrate a strategy using dc-biased ac electrokinetics to achieve controllability in direction and magnitude of the net fluid flow in pumping application.     

A Review of: “LEARNING LATER By Brian Findsen”

Many older adults do not use health information available on the Internet. Older adults residing in affordable housing were taught to use the NIHSeniorHealth.gov Web site. Participants were predominantly African American women with limited education and income (N = 42). Outcomes included changes in computer and health Web site navigation skills. Results showed significant improvements for all demographic groups in both computer and Web site navigation (p < .001). Older minority adults with no prior computer experience were willing and able to learn to use health Web sites. Success factors included an instructor familiar with the community, peer training assistants, and a focus on new learner needs.
