We proposed and fabricated multiscale transparent arteriole and capillary vessel models with circular cross sections of 10-500 μm using photolithography. The circularities of the fabricated 10, 50, and 500 μm diameter microchannels were 84.0%, 61.5%, and 82.3%, respectively. Next, we connected these different models to realize a circulation type blood vessel model simulating arteriole networks. We proposed a novel connection method using an intermediate connector made of wax, which we used to connect these models to make a circulation model. In flow experiments, the fabricated models showed no leakage and circulation models with seamless connections were achieved. 相似文献

Purpose: Brain-derived neurotrophic factor (BDNF) is well known for its potential to promote brain plasticity. It has been proposed that combining cognitive and physical exercise (CCPE) may have the potential to generate more synergistic benefits in cognitive function than either cognitive exercise (CE) or physical exercise (PE) alone. The purpose of this study was to examine acute responses of peripheral BDNF levels and cognitive performance to CE, PE, and CCPE.Methods: Thirteen healthy adult men participated in four experimental sessions; a 30-min CE, a 30-min cycling PE at an intensity of 60% peak oxygen uptake, a 30-min CCPE at the same intensity as PE, and a 30-min session of complete rest. Plasma BDNF levels and cognitive performance were measured before and after each session.Results: Both PE and CCPE significantly increased plasma BDNF levels (p?p?≥?.05), and there was no significant difference in peripheral BDNF levels between PE and CCPE (p?≥?.05). No session induced a significant change in cognitive performance (p?≥?.05).Conclusions: Our study suggests that CE and PE have different responses of peripheral BDNF levels and that CCPE had no additional or synergistic effect on peripheral BDNF levels compared with PE alone. This study offers further insights into the potential mechanisms underlying the respective roles of CE, PE, and CCPE for peripheral BDNF levels and cognitive performance. 相似文献

The Native American population is severely underrepresented in empirical test validity research despite being overrepresented in special education programs and at increased risk for psychoeducational evaluation. The structural validity of the Wechsler Intelligence Scale for Children – Fourth Edition (WISC‐IV) was investigated with a sample of 176, six‐to‐sixteen‐year‐old Native American children referred for a psychoeducational evaluation. Confirmatory factor analysis procedures replicated the normative first‐order factor structure and a higher‐order general ability factor that accounted for the greatest amount of common (69%) and total (33%) variance. These results support the structural validity of the WISC‐IV with a referred Native American sample and suggest that interpretation of the WISC‐IV scores should not neglect the strong general ability factor. 相似文献

This article presents a case study of quality management for print and electronic resource metadata, summarizing problems and solutions encountered by the Cataloging and Discovery Services Department in the George A. Smathers Libraries at the University of Florida. The authors discuss national, state, and local standards for cataloging, automated and manual record enhancements for data, user feedback, and statewide consortial factors. Findings show that adherence to standards, proactive cleanup of data via manual processes and automated tools, collaboration with vendors and stakeholders, and continual assessment of workflows are key to the management of biblio-graphic data quality in consortial academic libraries. 相似文献

Several recent, highly influential comparative studies have made strong statistical claims that improvements on global learning assessments such as PISA will lead to higher GDP growth rates. These claims have provided the primary source of legitimation for policy reforms championed by leading international organisations, most notably the World Bank and OECD. To date there have been several critiques but these have been too limited to challenge the validity of the claims. The consequence is continued utilisation and citation of these strong claims, resulting in a growing aura of scientific truth and concrete policy reforms. In this piece we report findings from two original studies that invalidate these statistical claims. Our intent is to contribute to a more rigorous global discussion on education policy, as well as call attention to the fact that the new global policy regime is founded on flawed statistics. 相似文献

Although the methods for medical education continue to evolve due to the development of medicines, the cadaver dissection course still plays a fundamental role. The cadaver dissection course allows students to learn to handle instruments correctly while actively exploring three-dimensional anatomy. However, dissection comes with the risk of accidental injury. In recent years, the number of classes offered for the cadaver dissection course has decreased while the amount of knowledge required in clinical medicine has increased. Simulation-based education (SBE) has been proven to be an effective educational method that enhances the development of practical skills by integrating learners' knowledge and skills. This study aimed to investigate the effect of SBE as a preparatory education course when taken prior to a medical student's enrollment in the cadaver dissection course. In the present study, an SBE assuming practical cadaver dissection course was performed in the Clinical Simulation Center. The frequency of injury rates per 1000 h of cadaver dissection course was significantly less in 2017 and 2018 compared to that in 2016. Two years after the implementation of the SBE, average student self-efficacy scores and written examination scores significantly increased, whereas self-contentment scores were relatively unchanged. The results showed that the implementation of SBE decreased the incidence of injuries and improved students' overall self-efficacy scores and increased acquisition of knowledge evident on written examination score. Therefore, SBE as a preparatory education course may effectively promote the combined development of dissection skills and anatomical knowledge in the subsequent fundamental cadaver dissection course. 相似文献

Is exam hell the cause of high academic achievement in East Asia? The case of Japan and the case for transcending stereotypes 
下载免费PDF全文
下载免费PDF全文 High student achievement across East Asia is often explained as an outcome of highly competitive, stress‐inducing college entrance exams across the region. This ‘exam hell’ drives students to study longer and harder than their peers worldwide, a race that leads—unsurprisingly—to higher marks in international comparisons such as the Programme for International Student Assessment (PISA). Yet, the race comes at a considerable cost: psychological pressure, forfeited childhoods, regimes of rote memorisation, lack of creativity and private outlays for cram schools. In this article, we seek to refute this outdated narrative by focusing on changes in Japanese education over the past three decades. We first analyse quantitative data for learning time based on three longitudinal surveys conducted by researchers in Japan to show that learning time for Japanese upper secondary students declined during 1980–2000 (Study 1). We then turn to analyse PISA 2015 data to show that now Japanese students study less than their peers in major Anglo‐American countries: the USA, the UK and Australia (Study 2). These findings run counter to well‐worn images frequently rehearsed in both the academic and popular literature. In helping to remove one of the most persistent stereotypes about East Asian education, we seek to help make visible other explanations for East Asian student achievement. 相似文献

ABSTRACTFacing increasing critique that PISA focuses too narrowly on cognitive achievement and human/knowledge capital, the OECD has recently shifted some of its focus to student happiness. The 2017 Students’ Well-Being report distinguishes between ‘happy schools’ and ‘unhappy schools’, showing that among students who combined high performance and life satisfaction, northern European countries topped the charts. Meanwhile, students in East Asian countries including Japan, China, Taiwan, Hong Kong, and Korea registered the lowest ‘life satisfaction’ scores among all participating countries. This piece points out some of the problems inherent in the OECD’s recent turn to happiness, problematizing the OECD yardstick of life satisfaction. Attempting to keep the critique constructive, we suggest that the OECD may want to consider using alternative metrics, then briefly highlight one developed in East Asia from different first assumptions: the Interdependent Happiness Scale. In conclusion we flag, but cannot answer, some related educational questions concerning policy, pedagogy, and priorities for the future. 相似文献
