国际化背景下农业文化遗产的认识和保护问题

随着人类对其遗产认识的不断进化,遗产概念无论是内涵还是外延,都在过去的二十年来突破了传统的认识范围。受到可持续发展和生态农业理念的直接影响,从21世纪初开始,农业文化遗产得到了国际社会越来越多的关注。中国是世界上农业历史最悠久的国家之一,也是目前世界上最大的农业国家。在这样的背景下,包括博物馆在内的遗产领域在国际化进程中如何为保护、传承和发展优秀农业文明在认识和实践上都有待进一步廓清。本文从若干认识问题和“全球重要农业遗产”及中国农业博物馆在农业文化遗产领域国际合作个案分析两个方面做了初步研究。     

Chinese academic journals: quality,issues and solutions

Twelve Chinese academic journals, indexed by SCI and financed by the National Natural Science Foundation (NNSF), were analysed using the 2000–2003 Total Citations and Impact Factor data from JCR. It is concluded that the quality of Chinese journals is generally low and has remained so despite recent government measures aimed at improvement. Several factors are influential – particularly the Chinese government's policy of encouraging submission to foreign journals. Finance, management, and the academic degree policy are also obstacles. It is suggested that the Chinese government should reconsider its current policies so as to encourage higher quality in domestic periodicals and thus a greater recognition of Chinese journals by the international academic community.

对人的历史的探询——再谈电影《芙蓉镇》

电影<芙蓉镇>是在同名小说的基础上通过宏大的历史叙事关照人性和人情,对人的历史进行了更深入的探询.影片把人物放在尖锐环境中去写,多侧面、立体化地展示生活中的小人物,塑造典型环境中的典型形象,再现一个时代,还原历史的真实.影片深刻揭示了人物从人性的压抑到生命的搏斗这一动人心魄的历史.     

正交试验设计法应用于煤泥浮选研究

采用正交试验设计研究捕收剂用量、起泡剂用量和矿浆浓度对浮选的影响。结果发现当起泡剂用量为1000g/t,起泡剂为120g/t,矿浆浓度为60g/L时,精煤产率最高,为82.88%。     

Assessment of three-dimensional joint kinematics of the upper limb during simulated swimming using wearable inertial-magnetic measurement units

The analysis of the joint kinematics during swimming plays a fundamental role both in sports conditioning and in clinical contexts. Contrary to the traditional video analysis, wearable inertial-magnetic measurements units (IMMUs) allow to analyse both the underwater and aerial phases of the swimming stroke over the whole length of the swimming pool. Furthermore, the rapid calibration and short data processing required by IMMUs provide coaches and athletes with an immediate feedback on swimming kinematics during training. This study aimed to develop a protocol to assess the three-dimensional kinematics of the upper limbs during swimming using IMMUs. Kinematics were evaluated during simulated dry-land swimming trials performed in the laboratory by eight swimmers. A stereo-photogrammetric system was used as the gold standard. The results showed high coefficient of multiple correlation (CMC) values, with median (first–third quartile) of 0.97 (0.93–0.95) and 0.99 (0.97–0.99) for simulated front-crawl and breaststroke, respectively. Furthermore, the joint angles were estimated with an accuracy increasing from distal to proximal joints, with wrist indices showing median CMC values always higher than 0.90. The present findings represent an important step towards the practical use of technology based on IMMUs for the kinematic analysis of swimming in applied contexts.     

理论修养是共产党员的立身之本

以德治国的关键是以德治党.共产党员是我国现代化建设的骨干力量,必须努力提高自身素质,加强自身修养,力求做到德才兼备,成为群众学习的楷模.而要达到这一标准,其最基本的途径是学习理论.该论文集中阐述了刘少奇同志论共产党员理论修养的重要思想,目的在于说明理论修养是共产党员的立身之本.
