I first encountered chiru during a wildlife survey in Qinghai in 1985.At that time,I was only aware that they lived on the high Tibetan Plateau,most of them between 4300-5000m in elevation and that they were confined to China,except for a few that strayed into India.  相似文献

中俄战略协作伙伴关系的历史   总被引:1,自引:0,他引:1  
中俄睦邻友好有着悠久的历史,其间也经历了风风雨雨,而2001年两国签署的《中俄睦邻友好合作条约》为两国关系的进一步发展奠定了法律基础。中俄两国的战略协作关系体现在许多方面,如建立多层次的对话机制,继续扩大两国公众之间的相互理解,加强文化、经贸交流等。中俄战略协作伙伴关系的保持和深化给两国的社会科学工作者提出了一些非常重要的任务,如加强与传媒的合作,促使两国彼此形成一种客观、友善和相互尊重的态度和看法;在解决两国研究中存在的分歧时,要立足于两国的睦邻友好合作关系;在研究两国过去的一些局部冲突问题时,应坚持历史的立场,不能把今天的评判标准用于对过去历史事件的评价,更不能在评论事件时从今天的认识出发做道德判断等。  相似文献

In 1885, Dr. Guilio Melotti published an Italian translation of a lecture on "Convulsive Tics with Coprolalia and Echolalia" given by Jean-Martin Charcot. Although this lecture often has been cited as an authoritative statement of Charcot's view, until now it has not been translated into English. The lecture presents a number of statements that appear nowhere else in Charcot's published corpus, including some that seem to contradict Charcot's other pronouncements on maladie des tics. Although the Melotti-Charcot lecture may portray Charcot's position accurately in many passages, the article most likely is a compilation from a variety of sources.  相似文献

This paper examines what marriage may have meant to African men within the Christian elite of Southern Rhodesia. Using mission and government sources, it argues that domestic, Christian marriage was important to elite African men as a way of allowing them to achieve adulthood while remaining in good standing with mission sponsors who generally objected to or feared indigenous ideas of patriarchal male adulthood. Tracing life histories of two American Board of Commissioners of Foreign Missions ministers, one who succeeded in remaining within the mission system and one who left, blacklisted, it explores how domestic, Christian marriage defused many of the missions' suspicions of elite African men, while providing a way to acquire the economic, social and political power associated with full adulthood within the local context.  相似文献

Beginning in the early 1950s, a series of epidemiological, biochemical, pathological, and animal studies demonstrated a link between cigarette smoking and lung cancer. A number of reputable scientists challenged these findings, but for a variety of reasons, including the behavior of the tobacco industry, historians have assumed that these objections were insubstantial and disingenuous. Viewing these objections in scientific and medical perspective, however, suggests that there was a legitimate and reasonable scientific controversy over cigarette smoking and lung cancer in the 1950s and early 1960s. That controversy had important consequences. A new chronic disease epidemiology emerged, transforming the role and importance of epidemiology to medical research. This new epidemiology supplemented Koch's postulates, establishing a statistical method that allowed for linking environmental factors to the etiology of chronic diseases. The 1964 report to the surgeon general, Smoking and Health, represented the denouement and codification of these developments. This reexamination of the scientific controversy over smoking in the 1950s and early 1960s provides an important context for understanding the subsequent public relations battles between the tobacco industry and public health after 1964.  相似文献

Presents three brief case studies to show how cognition and psychic activity were explored as energetic and economic transactions in a variety of experimental settings. First, in the 1870's German psychiatrist Emil Kraepelin began a search for an objective measurement of cognitive performance in which he engaged for several decades. His investigations resulted in a graphic representation of cognitive efficiency, the Arbeitscurve, delineating numbers of additions per time interval in close resemblance to representations of machine efficiency. Second, at the turn of the century American nutrition scientist and agronomist Wilbur Olin Atwater convinced himself in a series of precision measurements that the human motor was a perfectly closed input-output system and that any mental surplus in the form of cognitive energy transformation did not count as contradictions to the principle of the conservation of energy. Third, at the beginning of the 20th century and on the basis of Atwater's results, German psychiatrist Hans Berger stipulated a special form of psychic energy for mediating between the principle of the conservation of energy and mental causality. Berger attempted to quantify psychic energy as one factor of brain metabolism. In the three cases of precision investigations into psychic life presented here, the experimental space of psychophysiology turned mental activity into a form of machine-like behavior.  相似文献

The aim of this paper is to present the publication of the correspondence of Johann Bartholom?us Trommsdorff (1770 bis 1837) and to inform about the history of this project as well as the methodical proceedings and the content of these letters. The opportunities and limitations of the modern Trommsdorff research, based on the publication of his correspondence, will be shown. His contacts have been manifold and expansive. He corresponded with many famous scientists in pharmacy, chemistry, medicine and with important people of intellectual origin. Trommsdorff was a highly important person of the international European relationships in the field of pharmacy. Many publications certify the importance of the Trommsdorff-correspondence. The publication of these letters has opened new biographical aspects and allows to follow the connections and ways of communication in the new age of the foundation of scientific pharmacy.  相似文献
