Physiological comparison of intensity-controlled,isocaloric intermittent and continuous exercise†

VO2 fluctuations are argued to be an important mechanism underpinning chronic adaptations following interval training. We compared the effect of exercise modality, continuous vs. intermittent realized at a same intensity, on electrical muscular activity, muscular oxygenation and on whole body oxygen uptake. Twelve participants (24?±?5 years; VO2peak: 43?±?6?mL·?min^?1·kg^?1) performed (i) an incremental test to exhaustion to determine peak work rate (WR_peak); two randomized isocaloric exercises at 70%WRpeak; (ii) 1 bout of 30 min; (iii) 30 bouts of 1?min work intercepted with 1?min passive recovery. For electromyography, only the CON exercise showed change for the vastus lateralis root-mean-square (+6.4?±?5.1%, P?P?vs. 2.32?±?1.21?mM, respectively, for the CON and INT, P?vs. 356?±?301?sec, respectively, for the CON and INT, P?相似文献   

Environmental health and toxicology resources of the United States National Library of Medicine

For over 40 years, the National Library of Medicine's (NLM) Toxicology and Environmental Health Information Program (TEHIP) has worked to organize and to provide access to an extensive array of environmental health and toxicology resources. During these years, the TEHIP program has evolved from a handful of databases developed primarily for researchers to a broad range of products and services that also serve industry, students, and the general public. TEHIP's resources include TOXNET , a collection of databases, including online handbooks, bibliographic references, information on the release of chemicals in the environment, and a chemical dictionary. TEHIP also produces several resources aimed towards the general public, such as the Household Products Database , which helps users explore chemicals often found in common household products, and Tox Town , an interactive guide to commonly encountered toxic substances, health, and the environment. This paper introduces some of NLM's environmental health and toxicology resources.     

CD-ROM's acquaintances: What to do with the skeletons in our academic libraries

The University of Central Florida (UCF) Libraries had a large number of CD-ROMs accompanying books that had not circulated, did not work, or both. This article outlines the evaluation process of withdrawal.     

Planting the seeds … Tending the Garden … Cultivating the Student: Early Childhood Preservice Teachers as Literacy Researchers Exploring Beliefs about Struggling Readers and Diversity

This articles describes a qualitative research project investigating the effects of participation by preservice teachers in a literacy tutorial early intervention program that was based on a constructivist model utilizing self-reflection and inquiry. Seven recurring themes emerged from the data analysis providing little evidence of growth in culturally responsive teaching. The tutors, however, did learn valuable lessons about effective teaching of struggling readers in culturally diverse settings.     

Long-Term Effects of First-Grade Multitier Intervention

Abstract

The purpose of this study was to compare the long-term effects of 2 first-grade Response to Intervention (RTI) models (Dynamic and Typical RTI) on the reading performance of students in second and third grade. Participants included 419 first-grade students (352 in second grade and 278 in third grade after attrition). Students were classified based on first-grade screeners as at risk or not at risk and then based on their RTI (no risk [NR], relative easy to remediate [ER], and requiring sustained remediation [SR]). Students in the dynamic RTI condition had higher reading comprehension scores at the end of third grade. At the end of second grade, ER and SR students had lower reading scores than NR students. At the end of third grade, there were no differences in reading skills between ER and NR students, but SR students had lower scores than NR students. ER students in the dynamic RTI condition had higher reading scores at the end of second grade than those in the typical RTI condition. Limitations and directions for future research are discussed.     

The Effect of Training in Test Item Writing on Test Performance of Junior High Students

High stakes testing, a phenomena born out of intense accountability across the United States, produces instructional settings that marginalize both curriculum and instruction. Teachers and other school personnel have minimized instruction to drill and practice in an effort to raise standardized and criterion referenced test scores. This study presents an alternative to current practice that engages students in learning and increases their awareness of the internal aspects of standardized tests. The Test Item Construction Model (TICM) guides students through the process of studying test item stems and subsequently creating items using a 12 week process of incrementing from understanding to creating test items. Students grew in their understanding of the test item stems and the generation of these. An ANOVA did not yield significant differences between random groups of trained and untrained test writers. However, students in the experimental group demonstrated gains in understanding of test items.     

Lessons Learned from PISA: A Systematic Review of Peer-Reviewed Articles on the Programme for International Student Assessment

International large-scale assessments are on the rise, with the Programme for International Student Assessment (PISA) seen by many as having strategic prominence in education policy debates. The present article reviews PISA-related English-language peer-reviewed articles from the programme’s first cycle in 2000 to its most current in 2015. Five literature bases were searched, and results were analysed with SPSS. Results map the frequency of publications according to journal, country, and scientific discipline. They also summarise major themes within three identified categories: secondary analysis, policy impact, and critiques. Findings indicated that studies based on the PISA dataset has led to progress in educational research while simultaneously pointing to the need for caution when using this research to inform educational policy.
