RELATION OF PHYSICAL ACTIVITY TO MEMORY FUNCTIONING IN OLDER ADULTS: THE MEMORY WORKOUT PROGRAM

This paper describes a Phase I pilot study for the future development and field testing of a prototype CD-ROM program called the MEMORY WORKOUT. The MEMORY WORKOUT helps older adults increase and monitor changes in their daily physical and cognitive activity levels and these effects on physical functioning and memory. A holistic, multimodal model of memory provides the theoretical base for the design of the program. The primary purpose of this program is to enhance users' appreciation for the immediate and longer term benefits of exercise and physical activity on daily mental and physical function. Phase I results with 24 older adults (mean age = 71.2 years) indicate significant cross-sectional relationships among exercise time, exercise efficacy, and word list memory, and moderate to strong interest in improving memory and physical activity. Using Phase I prototype information, the goal of a Phase II project is to produce a complete, interactive, multimedia CD-ROM program that includes fitness training, assessment, and simulation components that are appropriate for adults over age 60.     

League tables in educational evidence-based policy-making: can we stop the horse race,please?

International large-scale student assessments (ILSAs) in education represent a valuable source of information for policy-makers, not only on student achievements, but also on their relationship with different contextual factors. The results are partly described in the official studies’ reports; more can be derived from the publicly released data sets. However, league tables are often the only evidence used in policy debates and decisions on education. Indeed, the comparison of student achievement across the participating educational systems is a legitimate proxy for estimating countries’ development and productivity, but the use of league tables more often turns into ‘horse-ranking’, ignoring the contexts of teaching and learning. This is often supported by the media, turning the use of results into their abuse. The purpose of this paper is to discuss the use and misuse of league tables in reporting ILSA results, vs. the use of data for in-depth analysis in order to make informed decisions.     

The information and communication technology competencies of students enrolled in school library media certification programs

As information and communication technologies (ICTs) become increasingly prevalent in modern society, improving students' competency with these technologies has become a key focus of 21st century education. Given the interdisciplinary and information rich nature of ICTs, many advocate for school librarians to actively promote their integrative use across the K-12 curriculum. This article asks, “Are school library media professionals adequately prepared for the task of integrating technology and skills into instruction?” It explores the perceived ICT competencies of students enrolled in school library certification programs and the use of ICTs in their school library education programs. Factors identified for discussion include the age of students enrolled in school library certification programs, the evolutionary process of ICT curricular integration, and perceived preparedness to integrate ICTs into instruction despite self-reported low competency levels with many of emerging technologies. Concluding comments encourage design of authentic and meaningful learning experiences that incorporate and promote the integrative use of ICTs in school library certification programs.     

Iterative learning control for fractional-order multi-agent systems

In this paper, we apply iterative learning control to both linear and nonlinear fractional-order multi-agent systems to solve consensus tacking problem. Both fixed and iteration-varying communicating graphs are addressed in this paper. For linear systems, a PD^α-type update law with initial state learning mechanism is introduced by virtue of the memory property of fractional-order derivative. For nonlinear systems, a D^α-type update law with forgetting factor and initial state learning is designed. Sufficient conditions for both linear and nonlinear systems are established to guarantee all agents achieving the asymptotic output consensus. Simulation examples are provided to verify the proposed schemes.     

Reading the Texts on Book Publishing: A New Body of Knowledge about an Old Body of Knowledge

The paper analyzes the role of publishing education in academia. The main question it asks is whether the publishing education remains to be focused on vocational training and as such resembles classical polytechnics, or is it gaining research component after it became part of European and American universities. The paper looks for answers to these questions in the body of texts that were published on book publishing in scientific and professional journals and monographs between 2003 and 2006.
