简析《正体类要》对湖湘张氏正骨学术思想的影响

《正体类要》是我国明代骨科一部卓有成就的重要专著,它对中医骨科学体系的发展有着不可磨灭的贡献,特别是对于骨科辨证用药的内治之法有诸多阐述,对后世伤科的内治有深远的影响。湖湘岳阳张氏正骨学术流派在发展过程中,较多地吸收并结合了《正体类要》重视伤科内治的精髓,并在传承中创新。本文分析《正体类要》对张氏正骨相关学术思想和应用的影响,认为张氏正骨流派在伤科辨证、内用方药等方面继承了《正体类要》重要的理念,逐步形成了张氏正骨气血为先,肝脾肾并重;理术结合,完善骨科体系;辨证论治,创新方药应用;针砭辅助,以达托补之功的学术思想。     

Structure-activity relationships of pyrethroids based on direct action on nerve

The structure-activity relationships of 30 synthetic pyrethroids have been studied by measurements of their direct action on isolated crayfish nerve cord. The concentrations of pyrethroids used to increase the frequency of spontaneous discharges to 200% of the control (NS₂₀₀), those to decrease the frequency back to the control level, and those to further decrease the frequency to 10% of the control were measured as indexes of the nerve action. These values did not necessarily run parallel with those for the lethal dose 50 or the knock-down 50. Large differences in NS₂₀₀ were found among optical isomers of tetramethrin and phenothrin, and there was a synergism with respect to the nerve stimulating action between (+) and (?) forms of tetramethrin. (+)-trans-Permethrin was unique in that it exhibited a potent insecticidal action with a very weak nerve action. It is necessary to compare the direct action on the target site for the purpose of establishing the true structure-activity relationships of synthetic pyrethroids.     

伯明翰学派电视研究的关键概念

电视研究是伯明翰学派的重要领域,他们的研究,特别是后期的受众研究,是对美国经验学派长期主导的电视效果研究的一个反驳。伯明翰学派将电视研究纳入一种历史的、社会的和文化的语境来考察,"霸权、意识形态、话语、文本、受众"是该学派电视研究的关键术语,这些术语记载着文化研究者思考电视的深入历程。     

论方东树文学鉴赏观

方东树把文、理、义作为诗文鉴赏的审美对象,并构建三者审美标准,不仅有整体上的体悟之论,更有具体而微的审美范式阐释,突破传统诗歌鉴赏的模糊性;以“通其辞”“通其意”为视角,构建“局部—整体—局部—整体”交互往复的鉴赏途径,深入到事理、文理、心理三者的赏析,此其对“通其辞,通其意”的创新;把“知人论世”作为诗文鉴赏的基本原则,不仅考量诗歌的社会功用,又考察诗人作品的时代色彩,扩大了“知人论世”的功用。这些鉴赏理论不仅有桐城派师承因素,更有汉宋兼容的学术文化背景;构筑了桐城诗学理论体系,具有重要的批评意义。     

Preference and adoption of Farmer Field School (FFS) Prosopis juliflora management practices: Experiences in Baringo District, Kenya

This research was carried out to evaluate the preference and adoption of harvesting, uprooting, stump burning, pruning and thinning practices for controlling the spread of Prosopis juliflora (prosopis) within Marigat Division of the Baringo District, Kenya. A survey methodology was employed using a random sample of 25 Farmer Field School (FFS) members and 5 non-FFS members from each of the five locations of Marigat Division. In total, 100 FFS members and 25 non-FFS members participated in the study; additional supplementary data were collected from the Kenya Forestry Research Institute (KEFRI), a major facilitator and trainer of the identified FFS activities and practices in the study area since 2004. More than 80% of the local community never undertook any form of prosopis management practice; however, this changed after FFS training, indicating an acquisition and retention of knowledge which probably diffused to the non-FFS counterparts, through either formal or informal ways. Harvesting was the most preferred (100%) and stump burning the least preferred (46%) practice of managing the spread of prosopis. The success and preference of any prosopis management practice was attributed to wood and non-wood benefits derived from prosopis and growing of animal fodder and food crops on rehabilitated land. More than 80% of respondents attributed ineffectiveness of any prosopis management practice to coppicing and viable seed banks of the tree, while 50% highlighted a lack of consistency and integration in carrying out management practices. The reported negative attitude towards prosopis changed after training with none of the view to eradicate it. Labor intensity and frequent regeneration of seedlings were identified as the major challenges faced during the implementation of prosopis management practices. In conclusion, the study shows that harvesting, uprooting, stump burning, pruning and thinning realized through consistent holistic integration contribute to containing the spread of prosopis trees in Baringo, Kenya.     

研究生院建设促进高水平研究型大学建设——纪念南京农业大学研究生院建院二十周年

南京农业大学是中国近现代高等农业教育的先驱,1914年开创了中国四年制农业本科教育的先河,1936年在中国率先开展了农科研究生教育,1981年成为全国首批博士、硕士学位授予单位,2000年经教育部批准成立了研究生院。研究生院建设促进了学位与研究生教育事业的快速发展,为研究型大学建设和世界一流农业大学建设奠定了重要基础。
