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

The purpose of this investigation was to compare external work and net energy expenditure during a bout of repetitive stretch-shortening cycles between competitive and recreational long-distance runners. Participants were divided into either competitive or recreational runners based on their maximal oxygen consumption and self-reported 1600 m times. The stretch-shortening cycle involved a repetitive hopping protocol on a force plate while measuring oxygen consumption and lactate accumulation for a total of 10 min. External work and net energy expenditure were calculated for 3 min after steady state was achieved and the ratio between these variables was utilised as an index of mechanical efficiency. Lower extremity stiffness was calculated during this interval as well. Net energy expenditure was significantly lower in competitive runners (152.6 ± 33.3 kJ) in comparison to recreational runners (200.6 ± 41.4 kJ) (P = 0.02) given similar amounts of external work performed in both groups (competitive runners = 65.6 ± 20.1 kJ, recreational runners = 68.8 ± 12.1 kJ) (P = 0.67). Index of mechanical efficiency was significantly different between competitive runners (43.2 ± 9.0%) and recreational runners (34.8 ± 5.3%) (P = 0.03). No significant differences were found in lower extremity stiffness (P = 0.64). Competitive distance runners can perform similar levels of external work with lower net energy expenditure and thus a higher index of mechanical efficiency during repetitive stretch-shortening cycles in comparison to recreational runners with similar values of lower extremity stiffness. This ability could possibly be due differences in muscle–tendon length changes, muscle pre-activation, cross-bridge potentiation and short-latency reflex responses as a result of training which should be considered for future investigation.  相似文献

This paper reports the findings of a qualitative case study that explored the role methods courses played in the education of preservice teachers at a large southeastern state university in the U.S.A. The paper portrays three distinct roles: the relevant role, the liberalizing role, and the critical role. The final section of the paper explores the implications of the study's findings for research and program development.  相似文献

Abstract

This paper presents a secondary analysis of data from a survey of teachers in the Jewish schools of three communities. Previous findings had shown that only 19% of teachers have professional training in both Jewish content areas and in the field of education, and despite incomplete professional backgrounds, little professional growth was required of teachers. What can be done to enhance and expand professional growth activities for teachers in Jewish schools? Analyses reported in this paper examine three possible “levers” for changing standards for professional growth: state licensing requirements for pre‐schools, state requirements for continuing education among professionally‐trained teachers, and community incentives for training of supplementary school teachers. Results indicate that pre‐school teachers in state‐licensed pre‐schools and supplementary school teachers who were paid for meeting a professional growth standard reported that they were required to attend more in‐service workshops, compared to other teachers who were not subject to these conditions. In addition, standards for the quantity of in‐service were higher among teachers who have stronger Judaic backgrounds and who are committed to a career in Jewish education.  相似文献
