This report identifies 13 instructional strategies for teaching adult numeracy skills that address issues of assessment, development of mathematical skills, and development of problem-solving skills. The rationale and suggestions regarding the following 13 instructional principles are described: address and evaluate attitudes and beliefs about learning and using math; determine what students already know about a topic before starting instruction; develop understanding by providing opportunities to explore ideas with representations and hands-on activities; encourage development and practice of estimation skills; emphasize mental math as a legitimate alternative computational strategy and encourage development of mental math skills; view computation as a tool for problem solving; encourage use of multiple solution strategies; develop students' calculator skills and foster familiarity with computer technology; provide opportunities for group work; link numeracy and literacy instruction; situate problem-solving tasks within meaningful, realistic contexts; develop students' skills in interpreting numerical or graphical information in documents and text; and assess a broad range of skills, reasoning processes, and dispositions, using a range of methods. A final section discusses implications, namely that their implementation will necessitate a reevaluation and redefinition of teachers' roles within the classroom and will require both collegial and institutional support.

This document, which was developed for participants in a videoconference examining a new approach to adult numeracy instruction, contains information and resources to help literacy trainers improve their numeracy programs. Presented first are the following: 12 instructional goals/principles that are based on the premise that numeracy educators must not simply teach computation but must also consider cognitive and dispositional goals; suggestions for staff developers and program administrators; and 8 classroom activities demonstrating the proposed 4-phase instructional approach (building on informal math, supporting sense making, developing interpretive skills, using integrated tasks). The second section includes brief discussions of selected recent initiatives to improve mathematics education (National Council of Teachers of Mathematics initiatives and standards, the Secretary's Commission on Achieving Necessary Skills, a recent working conference on adult mathematical literacy, and the adult numeracy practitioner network) and a 22-item annotated bibliography of resource materials for/about adult numeracy. Section 3 explains how to join the Internet's electronic numeracy forum, describes key electronic forums/databases concerned with adult numeracy and literacy issues, and provides technical information regarding accessing electronic adult numeracy resources. Appended is a math problem illustrating the proposed approach to numeracy instruction. (MN)

Shows by means of a mathematical example how algorithmic thinking and mathematical thinking complement each other. An algorithmic approach can lead to questions that deepen the understanding of mathematics material. (DDR)

Item does not contain fulltext, AIMS: Previous reports claimed that high sensitivity troponin T (HsTnT) is not associated with atrial fibrillation (AF) in the setting of acute ST-elevation myocardial infarction (STEMI) and primary percutaneous coronary intervention. However, the association of serial HsTnT levels and new-onset AF is unknown. We therefore assessed the temporal association between HsTnT levels and post-infarction AF. METHODS AND RESULTS: 830 patients enrolled in On-TIME II were included. HsTnT was assessed at baseline, and 24h and 72h after admission for STEMI. New-onset AF episodes were divided into three subgroups: AF during the first 24h of admission, AF 24-72h after admission and AF >72h after admission. ROC analysis and binary logistic regression were performed. Mean age was 62+/-12 years and 76% were male. Seventy-three patients developed new-onset AF: 41 patients developed AF during the first 24h of admission, 14 patients developed AF 24-72h after admission and 18 patients developed AF >72h after admission. HsTnT at baseline was associated with new-onset AF (area under curve (AUC) 0.596, p=0.008), but not with AF during the first 24h of admission (AUC: 0.539, p=0.414). HsTnT after 24h (AUC 0.792, p=0.001) and after 72h (AUC: 0.884, p<0.001) were associated with AF 24-72h and >72h after admission. HsTnT after 24h and 72h were stronger predictors of AF compared with HsTnT at baseline. In regression analysis, age (odds ratio 1.056, p<0.001), Killip Class >1 (odds ratio: 2.694, p=0.010) and HsTnT after 24h (odds ratio: 1.012, p=0.017) and after 72h (odds ratio: 1.035, p<0.001) showed the strongest association with post-infarction AF. CONCLUSION: Serial HsTnT plasma levels are associated with post-infarction, new-onset AF.

This study is devoted to the experimental analysis of the Strato-rotational Instability (SRI). This instability affects the classical cylindrical Couette flow when the fluid is stably stratified in the axial direction. In agreement with recent theoretical and numerical analyses, we describe for the first time in detail the destabilization of the stratified flow below the Rayleigh line (i.e. the stability threshold without stratification). We confirm that the unstable modes of the SRI are non axisymmetric, oscillatory, and take place as soon as the azimuthal linear velocity decreases along the radial direction. This new instability is relevant for accretion disks., Comment: 4 pages, 4 figures. PRL in press 2007
