It is believed that sport massage after intensive exercise might improve power and perceptual recovery in athletes. However, few studies have been done in this area. This study aimed to examine the effect of massage on the performance of bodybuilders. Thirty experienced male bodybuilders were randomly assigned to either a massage group (n = 15) or a control group (n = 15). Both groups performed five repetition sets at 75–77% of 1RM of knee extensor and flexor muscle groups. The massage group then received a 30-min massage after the exercise protocol while the control group maintained their normal passive recovery. Criteria under investigation included: plasma creatine kinase (CK) level, agility test, vertical jump test, isometric torque test, and perception of soreness. All variables were measured over 6 time periods: baseline, immediately after the DOMS inducing protocol, right after the massage, and 24, 48, and 72 h after the massage. Both groups showed significant (P < .001) decreases in jumping, agility performance, and isometric torque, but significant (P < .001) increases in CK and muscle soreness levels. The massage group in general demonstrated a better recovery rate. As such, a post-exercise massage session can improve the exercise performance and recovery rate in male bodybuilders after intensive exercise. 相似文献

Tables in documents are a widely-available and rich source of information, but not yet well-utilised computationally because of the difficulty in automatically extracting their structure and data content. There has been a plethora of systems proposed to solve the problem, but current methods present low usability and accuracy and lack precision in detecting data from diverse layouts. We propose a component-based design and implementation of table processing concepts which can offer flexibility and re-usability as well as high performance on a wide range of table types. In this paper, we describe a system named TEXUS which is a fully automated table processing system that takes a PDF document and detects tables in a layout independent manner. We introduce TEXUS’s own table processing specific document model and the two-phased processing pipeline design. Through an extensive evaluation on a dataset comprised of complex financial tables, we show the performance of the system on different table types. 相似文献

ABSTRACTThe purpose of this article is to explore how pedagogical visions inform our work as former classroom teachers and current teacher educators in rural and urban regions of the United States. Specifically, we explore the instructional decisions we make as we work to meet these visions in higher education. Teacher educators are charged with the task of fostering visionary teachers in today’s highly challenging educational landscape. We pose the question: How can teacher educators foster visionary beginning teachers without an examination of their visions for their practice? Using a self-study design, we examine the intersections of our pedagogical visions for teaching and the instructional actions we take to work toward our visions in higher education. Findings highlight specific instructional practices and strategies used to enact visions while providing a critical discussion of the lens of visioning within self-study research. 相似文献

Research on social protest movements raises many complicated methodological issues. This article systematically explains the methodological quandaries the authors confronted when studying demonstrations and online and offline activism by ethnic Turks in Germany, Belgium, and the Netherlands in support of the Gezi Park protesters in Turkey. It explains how participants were recruited and surveyed in this complex and extremely sensitive environment. It offers lessons learned that can be applied to other studies involving surveys of ethnic minorities engaged in social protest movements. More generally, they may also apply to surveys of any vulnerable population about sensitive issues. 相似文献

After decades of growth in environmental education (EE) in the US, the number of practitioners in the field remains unknown. A national study was conducted to estimate the field’s size through an online consumer survey panel stratified by race, ethnicity, and geographic region representing the US adult population. In addition to demographic data, three categorical questions assessed self-perceptions as environmental educators, the paid/unpaid nature of their work, and educational background in EE. Near one-fifth of the sample identified as environmental educators. Sample estimates of the overlap of environmental educators in formal education, non-formal, and unpaid (volunteer) work and their population numbers were used to calculate a conservative estimate of approximately 3.9 million environmental educators in the US Racial minority groups comprised 47% of the total number of environmental educators, indicating they were over-represented among those who consider themselves environmental educators compared to the general population. These results counter traditional assumptions that EE itself is not diverse, suggesting that inclusive practices may require more attention to who is currently excluded in organizations with low representation of minority communities. 相似文献

In this study, we examined framing in the U.S. and Chinese press coverage of the Fourth United Nations Conference on Women and the Non-Governmental Organizations Forum in Beijing in 1995. This study had 2 objectives: (a) to systematically assess the coverage of this global feminist event and the extent to which its critical areas of concern were communicated to the public, and (b) to illuminate the dynamics of framing in a comparative context and contribute to its further theoretical development. Employing quantitative and qualitative methods, this study found evidence of the operation of an anticommunist and an antifeminist frame in the U.S. coverage. Under the influence of dominant ideology, the U.S. coverage of the conference focused considerably on an extended criticism of China as a communist nation. The goals of the global feminist movement and their critical areas of concern appeared to hold far less immediacy and salience for the U.S. press than the need to assert dominant U.S. values. On the other hand, under the influence of communist ideology, the Chinese coverage reflected a proequality frame and a strong focus on the critical issues of concern to the global feminist movement. Despite the existence of a propagandistic emphasis on the country's extensive preparations as conference host as well as efforts to defend against Western criticism, nationalistic praise for China was far more subtle than originally expected. 相似文献

Cardiovascular disease, as the leading cause of patient death with chronic kidney disease, could be predicted by carotid atherosclerosis. The aim of the present study was to evaluate a possible relationship between serum soluble tumor necrosis factor-like weak inducer of apoptosis (sTWEAK) and Vitamin D levels with mean right/left carotid intima-media thickness (cIMT), in the hemodialysis (HD) patients. In this cross-sectional study, serums were obtained from 50 stable chronic HD patients and 39 healthy controls. The serum levels of sTWEAK, Vitamin D, intact parathyroid hormone (iPTH) in both groups, and cIMT were determined in HD patients by standard methods. Serum levels of sTWEAK were higher [808.8 (521.6–5032.4) pg/ml vs. 664.4 (487.4–2955.8) pg/ml (p = 0.006)] and Vitamin D levels were lower [13.4 (2.5–153) ng/ml vs. 27.8 (18.4–59.0) ng/ml (p = 0.001)] in the hemodialysis patients than in the healthy control. No important correlation was found between sTWEAK Vitamin D levels (r = 0.010/p = 0.946), and mean right(r = ?0.194/p = 0.178) and left (r = 0.061/p = 0.673) cIMT in the HD patients. Our study shows that sTWEAK levels are elevated in HD patients. This elevation has no association with the cIMT. 相似文献

Modern neuroscience increasingly relies on 3D models to study neural circuitry, nerve regeneration, and neural disease. Several different biofabrication approaches have been explored to create 3D neural tissue model structures. Among them, 3D bioprinting has shown to have great potential to emerge as a high-throughput/high precision biofabrication strategy that can address the growing need for 3D neural models. Here, we have reviewed the design principles for neural tissue engineering. The main challenge to adapt printing technologies for biofabrication of neural tissue models is the development of neural bioink, i.e., a biomaterial with printability and gelation properties and also suitable for neural tissue culture. This review shines light on a vast range of biomaterials as well as the fundamentals of 3D neural tissue printing. Also, advances in 3D bioprinting technologies are reviewed especially for bioprinted neural models. Finally, the techniques used to evaluate the fabricated 2D and 3D neural models are discussed and compared in terms of feasibility and functionality. 相似文献
