加州大学洛杉矶分校的Jared Diamond曾把人类列为"第三种黑猩猩"(第二种是倭黑猩猩).从基因上说,人类与黑猩猩的确非常相近;而且,两个不同群体的黑猩猩彼此间敌意甚深,非常喜欢打斗,在这一点上与人类如出一辙(参看上期本专栏"无知的野蛮人"). 相似文献

Background
Degenerative cervical myelopathy (DCM) is a recently proposed umbrella term for symptomatic cervical spinal cord compression secondary to degeneration of the spine. Currently literature searching for DCM is challenged by the inconsistent uptake of the term ‘DCM’ with many overlapping keywords and numerous synonyms.Objectives
Here, we adapt our previous Ovid medline search filter for the Ovid embase database, to support comprehensive literature searching. Both embase and medline are recommended as a minimum for systematic reviews.Methods
References contained within embase identified in our prior study formed a ‘development gold standard’ reference database (N = 220). The search filter was adapted for embase and checked against the reference database. The filter was then validated against the ‘validation gold standard’.Results
A direct translation was not possible, as medline indexing for DCM and the keywords search field were not available in embase . We also used the ‘focus’ function to improve precision. The resulting search filter has 100% sensitivity in testing.Discussion and Conclusion
We have developed a validated search filter capable of retrieving DCM references in embase with high sensitivity. In the absence of consistent terminology and indexing, this will support more efficient and robust evidence synthesis in the field. 相似文献4.

Science historian Ronald Numbers once remarked that the two most influential historians of science of the 20th century were Thomas Kuhn and Stephen Jay Gould. All historians are deeply familiar with Kuhn's work and influence, and most know of the remarkable impact Gould has had on evolutionary theory through both his professional and popular works. But little attention has been paid to the depth, scope, and importance of Gould's r?le as historian and philosopher of science, and his use of popular science exposition to reinforce old knowledge and generate new. This paper presents the results of an extensive quantitative content analysis of Gould's 22 books, 101 book reviews, 479 scientific papers, and 300 Natural History essays, in terms of their subject matter (Evolutionary Theory, History and Philosophy of Science, Natural History, Paleontology/Geology, Social Science/Commentary), and thematic dichotomies (Theory-Data, Time's Arrow-Time's Cycle, Adaptationism- Nonadaptationalism, Punctuationism-Gradualism, Contingency-Necessity). Special emphasis is placed on the interaction between the subjects and themata, how Gould has used the history of science to reinforce his evolutionary theory (and vice versa), and how his philosophy of science has influenced both his evolutionary theory and his historiography. That philosophy can best be summed up in a quotation from Charles Darwin, frequently cited by Gould: 'All observation must be for or against some view if it is to be of any service'. Gould followed Darwin's advice throughout his career, including his extensive writings on the history and philosophy of science. 相似文献
