政府规制与中国稀土产品出口增长的二元边际?--对2001-2012年微观贸易数据的实证分析

采用HS?6位数级微观贸易数据,计算2001—2012年中国稀土产品出口增长的二元边际,并进一步分析相对出口规制程度、相对产量与出口增长二元边际之间的相互影响,结果表明：中国稀土产品出口规制政策对稀土产品出口增长的集约边际和扩展边际都有促进作用,其中对集约边际的影响更大;而相对产量对二元边际有负面影响。在中国经济新常态下,随着稀土产品出口规制政策的逐步弱化,应加强对稀土产业的生产规制,提高产品附加值,实现从规模速度型粗放增长向质量效率型集约增长的转变;并积极开拓新的出口市场,促进稀土产业的良性扩张。     

中长跑运动员赛前训练的调控研究

运用实验法对参加全国第七届大学生运动会的江苏省大学生中长跑运动员和参加第十届全运会江苏队中长跑运动员的赛前训练期间的生理学指标进行跟踪测定、评价，对训练进行了调控。研究表明：用心率、心功能指数、尿蛋白、最大吸氧量、无氧功率、斯坦格试验与汉契试验、无氧闽等指标评定中长跑运动员赛前的机能状态有较强的实用性和针对性，但需结合项目的特点和训练实际，加强监控和调控，进行综合分析；中长跑赛前训练安排应以专项素质为主，突出速度和速度耐力的训练，速度力量在中长跑项目赛前训练要给予重视，负荷的安排是赛前训练的关键。     

权利法哲学视野中的体育腐败及其治理原则

摘要：针对体育腐败现象,主要通过文献资料法,从权利法哲学视角对体育腐败的定义、本质及其治理原则进行法理解读,目的在于揭示体育领域腐败的深层机理并得出治理之策。体育腐败是发生在体育领域之内的腐败,是享有体育公共权力的主体滥用或怠于行使体育公共权力的行为。体育腐败可以分为两种情形,一种是利用体育职权为自己或他人谋取不正当利益;另一种情形是虽未获取不正当利益,但滥用或怠于行使体育职权致使他人利益或公共利益受损。体育腐败的本质源于在体育权利与体育权力的博弈过程中体育权利之抑制以及体育权力之嚣长,因此,体育腐败的基本治理应遵循以下两个原则：体育权利张扬原则以及体育权力制约原则。体育制度和体育道德是实现体育权利张扬和体育权力制约最有效之措施,应以体现权利张扬和权力制约的体育制度规范之“硬法”辅之以体育道德伦理的教化和治理之“软法”。     

中介式调节作用在肥胖青少年锻炼经历与锻炼行为之间的关系研究

运用结构方程模型对均衡决策和自我效能在锻炼经历和锻炼行为中的作用进行分析,探讨肥胖青少年锻炼行为与锻炼经历、均衡决策、自我效能之间的关系.结果显示:均衡决策、自我效能在锻炼经历和锻炼行为的关系中起中介作用;自我效能对锻炼经历与均衡决策的关系,以及均衡决策与锻炼行为的关系起调节作用;均衡决策的中介效应受到自我效能的调节,并且均衡决策也是自我效能和锻炼行为关系的中介变量.自我效能对锻炼行为起间接中介作用,调节了锻炼经历与均衡决策、均衡决策与锻炼行为之间关系的作用轨迹和特征,促进了锻炼经历对锻炼行为的预测作用,影响了肥胖青少年的锻炼行为.     

From the Sacral to the Moral

ABSTRACT

This article examines sleeping practices and their spiritual meanings in English society. Sleep is one of the most fundamental experiences of everyday life, and this article examines how its temporal and spatial dimensions were shaped by a wide range of confessional groups according to theologies of salvation and resurrection from 1660 to 1700. The practices, rituals and objects that surrounded and sanctified the bedside highlight distinctive forms of sleep-piety that were supported by shifts in the provision and use of domestic space, by the pastoral objectives of Church divines and dissenting ministers, and by a flourishing genre of published spiritual guides that promoted private household devotions. This comparative study of sleeping practices nuances existing historical narratives about the fragmented religious landscape of these years. Most importantly, however, it offers a justification of the centrality of pious sleeping routines to the everyday experience of devotional practice by tracing the ways in which religious beliefs were embodied through subjective physical performances of sleep.     

Sleep quality in athletes under normobaric hypoxia equivalent to 1500 m altitude: A polysomnographic study

Abstract

In the present study, we evaluated the duration of slow-wave sleep (Stage 3 and 4) and total delta power (< 3Hz) in all-night non-rapid eye movement (NREM) sleep electroencephalograms (EEGs) of athletes during normobaric hypoxia at simulated altitudes of 1500 m. Seven male athletes slept for two nights in a normoxic condition and one night in an hypoxic condition equivalent to an altitude of 1500 m. Whole-night polysomnographic recordings, thoracic and abdominal motion, nasal and oral airflow, and blood oxygen saturation (SpO₂) were recorded. Visual sleep stage scoring and fast Fourier transformation analyses of EEG were performed using 30-s epochs. Mean and minimum SpO₂ decreased significantly during sleep in the hypoxic condition. Between groups, changes in heart rate, respiratory disturbance measures including apnoea and hypopnoea, slow-wave sleep and total delta power of the all-night NREM sleep EEG were small and non-significant for the hypoxic condition_. However, individual difference in time at an SpO₂ below 90% were large in the hypoxic condition, and both slow-wave sleep and total delta power of all-night NREM sleep EEG decreased in three participants who spent a prolonged time below 90% SpO₂. The present results suggest that monitoring time below 90% SpO₂ is recommended when studying individuals' living-high schedule even under hypoxic conditions equivalent to an altitude of 1500 m.     

从美国宪法看三权分立

相对均衡的政治结构在美国作为当今世界头号强国的地位中起着至关重要的核心作用。这种制衡机制既来源于开国时期制宪者们的智慧，同时又与各州的自主愿望密切相关。“9·11”后，美国以国家安全为借口，使总统的权力日趋扩大，分权的不平衡性开始凸显。
