“In the beginning there was the word.” Speech the means ofcommunication, creates the foundation for all human relationships with one another. Verbalismus and the abstract formation of an idea were expressions for overvaluation of speech. Natural scientists showed, from translations of ancient works, that this was something to watch for or a process already completed: further investigation through personal experiment orobservation test are unnecessary. 相似文献

HealthStages is a health promotion program of OASIS, a national arts and humanities, health, and volunteer organization for older adults. It was developed by a unique not-for-profit organization and university collaboration using state-of-the art curricula and current research to enhance successful aging. Rowe and Kahn's (1997) model of successful aging provided the overall framework for the project, and Prochaska and DiClemente (1983) Stages of Change component of the Transtheoretical Model of Behavior Change guided our curriculum development, research questions, and program evaluation. HealthStages uses evaluations of individual courses to assess participant expectations, new areas of interest, and appropriateness of courses. Outcome measures assess participants' changes as a result of particular courses within the program. Using a longitudinal survey design, a sample of HealthStages participants is compared to a random sample of older adults not involved in the program, comparisons are made on their health, health behavior, healthcare utilization, activity, and functioning over time. HealthStages is a comprehensive health promotion program designed to provide courses in a variety of topic areas at differing levels of readiness to change and to measure changes over time. The unique collaboration offers benefits to OASIS and its members as well as to faculty and students of Washington University. 相似文献

Until recently, the physiological demands of cycling competitions were mostly reflected by the measurement of heart rate and the indirect estimation of exercise intensity. The purpose of this case study was to illustrate the varying power output of a professional cyclist during flat and mountain stages of a Grand Tour (Giro d'Italia). Nine stage recordings of a cyclist of the 2005 Giro d'Italia were monitored using a mobile power measurement device (SRM Trainingssystem, Julich, Germany), which recorded direct power output and heart rate. Stages were categorized into flat (n = 5) and mountain stages (n = 4). Data were processed electronically, and the overall mean power in flat and mountain stages and maximal mean power for various durations were calculated. Mean power output was 132 W +/- 26 (2.0 W x kg(-1) +/- 0.4) for the flat and 235 W +/- 10 (3.5 W x kg(-1) +/- 0.1) for the mountain stages. Mountain stages showed higher maximal mean power (367 W) for longer durations (1800 s) than flat stages (239 W). Flat stages are characterized by a large variability of power output with short bursts of high power and long periods with reduced intensity of exercise, whereas mountain stages mostly require submaximal, constant power output over longer periods. 相似文献

Activation of the hamstrings has been discussed as a measure for reducing strain on the ACL during jump landings in alpine skiing. The current study tested the hypothesis that hamstring and quadriceps activation can be voluntarily increased by the athlete. Specifically, two different instructions – to increase hamstring activation or to increase upper-leg co-contraction – were compared to normal landings. Eight members of the German national and junior national squad in freestyle skiing (age 19.6 ± 3.8 years; weight 66.1 ± 13.2 kg; height 172.2 ± 7.7 cm) performed 12 jump landings on a prepared run, 4 with no specific instruction, 4 with the instruction to generally activate the thigh muscles, and 4 with the instruction to specifically activate the hamstrings. Electromyographic (EMG) signals were recorded on the biceps femoris (BF), semitendinosus (ST), vastus lateralis (VL), rectus femoris (RF) and vastus medialis (VM). EMG activation levels were integrated over three landing phases and analysed with a repeated measures ANOVA. The instruction produced a significant main effect in ST (p = .026), VM (p = .032) and RF (p = .001). Contrary to previous research, the current study suggests that hamstring muscle activation levels can be voluntarily increased during jump landing, particularly in co-activation with its antagonists. 相似文献

This forum presents Thailand's National Information Technology (IT) Plan and comments on the plan by three international experts: Seymour Goodman, Heinrich Reinermann, and G. Russell Pipe. The plan, which was prepared for Thailand's National IT Committee by the National Electronics and Computer Technology Center, is striking for its explicit consideration of social as well as economic goals in its specific objectives and implementation proposals. Agenda item 1 of the plan is to 'Invest in an Equitable Information Infrastructure: To Enhance Human Ability and Enhance Life Quality.' Implementation of the plan is proceeding well, although somewhat more slowly than anticipated, and support for the original goals and objectives remains strong. 相似文献
