对热应激、脑损伤与机体免疫间关系的研究

高温环境下长时间暴露或长时间、大强度运动容易导致脑组织微观结构损伤、机体免疫机能下降。损伤机制与高温、自由基、磷脂酶A2、氨基酸及NO代谢有关。高温环境下脑损伤与机能免疫机能下降之间可能存在直接关系。     

The rhetorical construction of Popular Front France in the fascist Italian press during the ‘Paris, 1937’ international exhibition

This article will discuss propaganda in the press used by the Italian fascist regime to create and disseminate a negative image of France and socialism. The ‘Paris, 1937’ exhibition represented a pretext for the Italian press to attack the Popular Front on both policy and competence. Manipulating information, the propaganda fabricated an idea of ‘otherness’, presenting France as the chaotic antithesis to the orderly Italian regime. France was presented as a country full of drunks and idlers, as a nation descending into chaos due to the social economic reforms of the Blum government; images that were juxtaposed with a state thriving under fascist corporatism. With the use of archive files and press-clippings, this work intends to illustrate the construction of stereotypes to feed the fear of socialism in Italy by the fascist press.     

三峡库区腹地县域耕地压力研究——以奉节县27个乡镇为例

本文以奉节县的27个乡镇为研究区,运用景观生态学理论、地理信息系统和统计分析方法,借助Erdas8.5、ArcGIS9.3以及Fragstats3.3软件,分析了三峡库区腹地奉节县27个乡镇2010年耕地压力空间分布规律,讨论了耕地压力与土壤侵蚀的关系及优化调控措施。结果表明:①研究区耕地受其自然地理条件的影响,在不同岩性、地貌、坡度上分布差异显著;②耕地压力空间差异较显著,长江以北大部分乡镇耕地压力指数小于1,而南部乡镇耕地压力指数基本上大于1.5。根据耕地压力指数偏离1的程度且经校正将研究区分为4类区,包括无压区、边缘区、低压区和高压区;③由于北部地区开垦了大量的坡耕地,缓解了耕地压力,使得北部地区耕地压力比南部地区小,但土壤侵蚀综合指数较南部地区大,即生态破坏较严重。因此,通过大量开垦坡耕地来缓解耕地压力虽能暂时起到作用,但是从长远来看会加快耕地水土流失的速度,最终会大大增加耕地压力;④缓解研究区耕地压力、维护生态平衡要结合城镇化进程,促使人口向非农产业转移,通过异地供给方式解决粮食问题,降低粮食自给率;在推行生态退耕的同时也要保护好现有中、优等别耕地;调整农业结构,形成以种植粮食作物为基础,畜牧业、林果业、药业为主导的农业结构。     

基于随机舍弃邻域的低照度图像去噪算法

场景中的光照条件对数字图像的质量具有决定性影响,当光照强度较弱时,获取的低照度图像对比度低,信噪比较差,给后续图像处理工作带来困难。经典基于邻域的图像去噪算法依据图像相邻像素之间的灰度连续性,往往在去除噪声的同时导致图像边沿模糊。文章介绍一种基于邻域像素随机舍弃的低照度图像去噪算法。算法首先根据像素邻域的拉普拉斯算子自适应地调节舍弃概率,并对邻域内各像素进行随机舍弃估计;然后以邻域的方差最小化为目标函数并添加偏差项进行约束,通过协调方差项与偏差项获取保留像素的权重估计;最后根据邻域像素的权重迭代估计图像像素值。实验仿真结果显示该算法能够在低照度条件下有效去除图像噪声,恢复原始图像信息。     

Reception of Arthur Sutherland Neill＇s pedagogical concept and his Summerhill School in Hungarian and German pedagogical literature and press

Arthur Sutherland Neill is one of the most debated personalities among the representatives of the classic reform pedagogy, due to his pedagogical concept and its practical realization, and his Summerhill School, equally. He is often mentioned during public debates, where mostly the ＂three S＂--＂sex, swearing and smoking＂, are existing as subject of the debates. While analyzing publications about Summerhill School appearing in Hungarian and German pedagogical special literature and press, a kind of polarized attitude has been realized towards the conceptions and school： Some talk about him admiringly; others criticize him while emphasizing the concept＇s drawbacks and unique features.     

A Decade of Coverage (1990–2000): The Mainstream Library Press and Its Coverage of Eastern Europe and the Soviet Union and Its Successor States

ABSTRACT

This study examines the coverage of Eastern Europe and the Soviet Union and its successor states by U.S. journals indexed in Library Literature between 1990 and 2000. Seventy-one journals were evaluated according to subject content, geographical coverage, document type, and year of article publication. The study found that the majority of articles focused on domestic and foreign library activities. Coverage peaked between the years 1990 and 1994, with a steady decline after that. The study reports on differences in coverage by peer-reviewed and non-peer-reviewed journals over this decade.
