反思轮胎特保案败诉的原因及教训     

刘耀宏 《通化师范学院学报》2011,32(5):86-88

轮胎特保案败诉,究其原因,与世贸组织争端解决机制自身缺陷及美国针对中国特保的立法有着密切关联。反思其教训,政府、行业、企业要采取措施,协调运作,实现资源利用的最大化,以期构筑应对国外反倾销、特保调查在内的全方位贸易救济机制,从而解决贸易摩擦,维护自身权益。  相似文献

村落权威研究综述     

陶琳 《保山师专学报》2011,30(1):19-23

村落权威在村落中的积极行为以及沟通村落内外的中介作用,使它吸引了众多国内外学者的注意,纵观国内外研究,村落权威研究经历了从静止的共时研究转向动态的过程研究,由外在的结构—功能研究向行为者内在行为观念研究的转向,同时村落权威研究也呈现出研究方式相互渗透,相互影响的发展趋势。  相似文献   

农村劳动力转移培训的个案研究——对“云和师傅”培训的调查分析     

刘超 《职业技术教育》2011,(25)

云和师傅是云和县人民政府建立的具有本地特色的农村劳动力转移就业培训模式。其由云和县农村劳动力素质培训中心统一实施,主要分为后备云和师傅专业技能培训和云和师傅后续素质培训两种,培训领域涉及当地农业生产的多个行业,主要采用本地集中培训的模式。但其在发展过程中也表现出培训结构失调、模式单一、政府过度主导等问题,为此,其在未来发展中应重视对女性及偏远乡镇人口的培训、采用更加灵活的培训模式、增强对政府的监督。  相似文献   

Dynamics and manipulation of ferroelectric domain walls in bismuth ferrite thin films     

Shuyu Xiao  Yaming Jin  Xiaomei Lu  Sang-Wook Cheong  Jiangyu Li  Yang Li  Fengzhen Huang  Jinsong Zhu 《国家科学评论(英文版)》2020,7(2):278

Ferroelectric domain walls differ from domains not only in their crystalline and discrete symmetry, but also in their electronic, magnetic, and mechanical properties. Although domain walls provide a degree of freedom to regulate the physical properties at the nanoscale, the relatively lower controllability prevents their practical applications in nano-devices. In this work, with the advantages of 3D domain configuration detection based on piezoresponse force microscopy, we find that the mobility of three types of domain walls (tail-to-tail, head-to-tail, head-to-head) in (001) BiFeO₃ films varies with the applied electrical field. Under low voltages, head-to-tail domain walls are more mobile than other domain walls, while, under high voltages, tail-to-tail domain walls become rather active and possess relatively long average lengths. This is due to the high nucleation energy and relatively low growth energy for charged domain walls. Finally, we demonstrate the manipulation of domain walls through successive electric writings, resulting in well-aligned conduction paths as designed, paving the way for their application in advanced spintronic, memory and communication nano-devices.  相似文献   

论课程品质及课程力自增的哲学理据     

钟发全 《中国教育科学(中英文)》2021,(1):91-98

新课程品质及课程力自增,是新课程改革呈旺盛势态的标志。充实哲学理据以接近本质,建议从三个方面着力解决问题:一是理顺新课程改革的结构性问题,能正确理解课程与课程力之间的主体和载体的关系,全面实现自增的旨趣;二是针对课程品质及课程力自增的合理性论证与追述,能着力于内生长与外发展中存在的历史流变,发现不合理存在的原因,从而全...  相似文献   

从“文斗”到“武斗”:礼法约束下“斗秧歌”田野调查     

滕希望  郭玉成 《上海体育学院学报》2020,(3):73-83

以海阳大秧歌中的民俗武术活动“斗秧歌”仪式为个案,运用田野调查等方法,从民俗学视角对“斗秧歌”的过程及民俗语境进行分析。认为:海阳大秧歌吸收了军事武术中的兵法谋略与民间武术技术动作,族群生存斗争与比武较技是“斗秧歌”吸收武术元素的重要动因,其逻辑形式表现为礼法约束下由“文斗”到“武斗”的递进,“文斗”体现兵法谋略智慧,武术是“武斗”的主要支撑力量。“斗秧歌”受到礼法约束,以强化乡间社会秩序的稳定,反映了中国传统社会治理中的礼法并施思想。剖析其民俗语境发现,“斗秧歌”是族群生存抗争的仪式手段、护卫生存环境的民间演习、展示个人魅力的艺术舞台,也是地域武术传播的民俗载体。武术与“斗秧歌”之间的融合互动关系,显示武术与民俗活动深厚的历史渊源及武术具有的多元价值属性。  相似文献   

加快新农村建设强化农村转移劳动力培训     

商庆军  赵吉云 《成人教育》2007,(2):74-75

新农村建设是国家为了实现农业、农村经济建设全面发展而制订的一个宏观目标。最终目的是要解决三农问题,实现农村的发展和农民的共同富裕。要想使农民富裕,根本出路是农村剩余劳动力向城镇和非农产业转移。但是农民文化水平较低成为农村剩余劳动力有效转移的最大障碍。因此,对农村转移劳动力进行有效的培训成为必须;如何充分利用有限的培训资源,开展有效的转移劳动力培训成为必须考虑的问题。  相似文献   

Postural balance and rifle stability in a standing shooting position after specific physical effort in biathletes     

Dorota Sadowska  Justyna Krzepota  Andrzej Klusiewicz 《Journal of sports sciences》2019,37(16):1892-1898

The aim of the study was to evaluate the effect of maximal specific physical effort on postural balance and rifle stability in biathletes in a standing shooting position. The study included 10 junior elite biathletes. The measurements were taken with the Vicon system and AMTI force platform. Postural balance and rifle stability characteristics were determined at rest as well as 1 and 5 min post maximal specific physical effort which was performed on a ski ergometer and continued until exhaustion. Maximal physical effort exerted a significant effect on all examined postural sway and rifle sway characteristics. The duration of the post-exercise changes was longer than 5 minutes. Higher post-effort rifle sway was observed in the vertical direction than in the across the shooting line direction. Post-effort postural balance impairment in the shooting line was much greater than in the across the shooting line direction. Moreover, a strong correlation was found between postural balance and rifle stability. Maximal physical effort influenced postural balance and rifle stability during aiming. Rifle sway during aiming in a standing shooting position seems to be coordinated with the postural sway of the biathlete’s body. Thus, an increase in postural sway contributes to greater sway and lesser stability of the rifle.  相似文献
