人与自然关系的主体原因探析

人作为主体,在人与自然关系中起着至关重要的作用。人口因素对自然环境的影响,主要 包括人口数量因素对自然环境的影响和人口质量因素对自然环境的影响。要改善人对自然环境的影 响,必须从人的自身去寻找对策,变不利因素为有利因素,实现人与自然的和谐统一。     

9.11事件后地缘政治观的反思

地缘政治这一传统观念在经济全球化、政治趋向多极化的背景下,遇到了强有力的挑战。9.11事件后美国政府正在重构其地缘逻辑思维。适时提出“时缘政治”和“人缘政治”概念,全面审视世界政治格局。我国应从国家利益出发,积极重构地缘战略格局。     

对安乐死立法的法理学思考

安乐死立法，是人类对待生命的正确的理性选择，是社会发展到一定历史阶段的必然结果。安乐死在西方一些国家已经立法并实施。而在我国，由于几千年传统的儒家化思想习俗的影响，安乐死立法阻力颇大。但无论从安乐死的道德伦理的角度。安乐死的医学伦理的角度，还是从安乐死的法理学分析看，安乐死立法，对于健全我国的法制建设，完善对生命保护的法律体系，加大对生命的保护力度，不但具有理论上的必要性，也具有积极的现实意义。     

学风建设深层问题的几点思考

高校学风建设要以学生为中心，一切从学生的根本利益出发，对学生全面负责。通过深化教育教学改革，充分调动学生学习的积极性、主动性、创造性并培养学生优良的道德品质是学风建设的根本目的。     

汉语"道歉"话语模式

道歉是交际中的一种补救性施事言语行为，也是一种礼貌的社会行为。其基本功能是为一项冒犯行为提供补救办法，恢复社会平衡与和谐。从语言形式来看，道歉具有语义句法程式化和规约化的普遍特征。本用语篇补全测试的问卷形式通过对汉语中道歉行为实施的调查、对所选策略进行了分类统计，结果表明道歉的话语模式包括多种策略和手段的组合，但策略的选用在很大程度上受到如权势、距离等因素的制约，说明道歉行为对化等因素的依赖。     

Measurement precision of body composition variables in elite wheelchair athletes,using dual-energy X-ray absorptiometry

The purpose of this study was to assess the reproducibility of body composition measurements by dual-energy X-ray absorptiometry (DXA) in 12 elite male wheelchair basketball players (age 31 ± 7 years, BMI 21 ± 2 kg/m² and onset of disability 25 ± 9 years). Two whole body scans were performed on each participant in the supine position on the same day, using Lunar Prodigy Advance DXA (GE Lunar, Madison, WI, USA). Participants dismounted from the scanning table and were repositioned in-between the first and second scan. Whole body coefficient of variation (CV) values for bone mineral content (BMC), fat mass (FM) and soft tissue lean mass (LTM) were all <2.0%. With the exclusion of arm FM (CV = 7.8%), CV values ranged from 0.1 to 3.7% for all total body and segmental measurements of BMC, FM and LTM. The least significant change that can be attributed to the effect of treatment intervention in an individual is 1.0 kg, 1.1 kg, 0.12 kg for FM, LTM, and BMC, respectively. This information can be used to determine meaningful changes in body composition when assessed using the same methods longitudinally. Whilst there may be challenges in the correct positioning of an individual with disability that can introduce greater measurement error, DXA is a highly reproducible technique in the estimation of total and regional body composition of elite wheelchair basketball athletes.     

Lower limb alignment characteristics are not associated with running injuries in runners: Prospective cohort study

There is conflicting evidence on the association between lower limb alignment characteristics and the incidence of running-related injury (RRI). Therefore, the primary aim of this study was to investigate the association between lower limb alignment characteristics and the incidence proportion of RRI in a convenience sample of recreational runners. A total of 89 recreational runners were included in this prospective cohort study. These participants had been running for at least six months and were injury-free at baseline. Lower limb alignment measurements were conducted in order to calculate lower limb discrepancy, Q-angle, subtalar angle and plantar index. All participants also answered a baseline and biweekly online surveys about their running routine, history of RRI and newly developed RRI over a period of 12 weeks. The prevalence of previous RRI and the 12-week incidence proportion of new RRI were calculated. Logistic regression analysis was performed to estimate the association between lower limb length discrepancy, Q-angle, subtalar angle and plantar ach index with the incidence proportion of RRI. The prevalence of previous RRI was 55.1% (n?=?49). The 12-week incidence proportion of new RRI was 27.0% (n?=?24). Muscle injuries and tendinopathies were the main types of RRI identified. The lower leg and the knee were the main anatomical regions affected. We did not find significant associations between lower limb length discrepancy, Q-angle, subtalar angle and plantar arch index and injury occurrence.

英语双关语的翻译

双关语是最难翻译的修辞现象之一，英语双关语的翻译策略通常有以下几种。对等翻译法将双关语译为相同的双关语，主要适用于建立在人类共同认知基础上的双关语和部分结构双关语；变通对等法是通过创造双关语译为不同的双关语，主要适用于思想主题意义不大严肃的文字游戏类双关语。体现不同文化特色和语言特点的双关语有时也可以通过语音、语义或形式手段译为类双关语，还可以通过释义、加注等方法进行补偿。双关语的翻译还包括谐音法、省略法、移植法等。
