背景虽然当前已有一些评估卫生保健指南可靠性的工具,但仍缺乏针对制定指南实际步骤的指导。针对指南制定者们所需考虑的相关资源和工具,我们系统研发了一份全面的条目清单,但这并不意味着每篇指南都需遵守该清单的所有条目。方法我们检索了国际指南制定机构的指南制定手册、指南的指南(主要是来自国际和国家机构以及专业学会的方法学报告),以及提供系统指导的最新文章。经过反复评价这些资料,尽可能全面地罗列和提取条目,并制定与指南有关的重要主题。通过反复讨论,我们对条目进行评价以去重和补漏,同时邀请指南制定专家对所增加的条目进行修改并提出建议。结果我们制定了一份包含18个主题、146个条目的清单,并建立了帮助指南制定者应用这些条目的网站。这些主题和条目涵盖了指南从规划、完成、实施和评估的全过程。最终的清单版本也包括了培训所需的资料以及应用这些条目时用到的方法学参考文献的链接。解释本清单将提供给指南制定者用作参考。仔细考虑清单中的条目将有助于指南的制定、实施和评估,我们也将会通过大众反馈来修订并持续更新清单。

近年来实效性临床试验受到更多重视,尤其在传统医学临床评价研究领域。为了提高实效性临床试验报告的质量,CONSORT声明组和医疗保健体系中的实效性随机对照临床试验(pragmatic randomized controlled trials in health care systems,PRACTIHC)小组对《CONSORT声明》进行了修改,以帮助读者评估试验质量和结果的可靠性。实效性试验报告指南,作为《CONSORT声明》的一个特殊扩展,能在报告、评价和应用实效性试验方面帮助编辑、系统评价者、试验设计者和决策者评估实效性试验报告中的信息,判定其结论是否适用,以及干预措施是否可行、可否被接受。2005年1月和2008年3月,在加拿大多伦多分别举行了为期两天的会议来探讨提高随机对照试验对卫生保健决策贡献的方法,焦点集中于实效性试验。2005年会,后扩展版草案修订清单发送至编写组成员,经过几次修订,编写组起草了一份摘要草案。在2008年讨论并修改了这一草案。这份草案发给CONSORT声明组以供修改并发表。这份声明的扩展版提出了对8个条目的补充。及时向国内读者和临床试验研究人员介绍该指南有重要的现实意义和学术价值。北京中医药大学循证医学中心刘建平教授等在短时间内翻译了该指南。本刊希望通过介绍中文版"提高实效性临床试验报告的质量——《CONSORT声明》的扩展"以提高国内实效性临床试验报告的质量,相信也有助于改进试验设计的方法学质量。

A framework for quantifying properties of 3-dimensional movement-based signals

引用

Current Zoology 2010年第3期56卷 327-336页

作者： shaun TD NEW Richard A PETERS ARC Centre of Excellence in Vision Science Division of EvolutionEcology & GeneticsResearch School of BiologyThe Australian National University

Understanding how signal properties are optimized for the reliable transmission of information requires accurate de- scription of the signal in time and space. For movement-based signals where movement is restricted to a single plane, measure- ments from a single viewpoint can be used to consider a range of viewing positions based on simple geometric calculations. However, considerations of signal properties from a range of viewing positions for movements extending into three-dimensions （3D） are more problematic. We present here a new framework that overcomes this limitation, and enables us to quantify the extent to which movement-based signals are view-specific. To illustrate its application, a Jacky lizard tail flick signal was filmed with synchronized cameras and the position of the tail tip digitized for both recordings. Camera aligmnent enabled tl^e construction of a 3D display action pattern profile. We analyzed the profile directly and used it to create a detailed 3D animation. In the virtual environment, we were able to film the same signal from multiple viewing positions and using a computational motion analysis algorithm （gradient detector model） to measure local image velocity in order to predict view dependent differences in signal properties. This approach will enable consideration of a range of questions concerning movement-based signal design and evolu- tion that were previously out of reach [Current Zoology 56 （3）： 327-336, 2010].

To forage or hide？ Threat-sensitive foraging behaviour in wild, non-reproductive passerine birds

引用

Current Zoology 2014年第6期60卷 719-728页

作者： shaun TURNEY Jean-Guy J. GODIN Department of Biology Carleton University Ottawa ON K1 S 5B6 Canada Department of Biology McGill University Montreal QC H3A 1B 1 Canada

Because antipredator behaviours are costly, the threat-sensitive predator avoidance hypothesis predicts that individual animals should express predator-avoidance behaviour proportionally to the perceived threat posed by the predator. Here, we experimentally tested this hypothesis by providing wild passerine birds supplemental food （on a raised feeding platform） at either 1 or 4 m from the edge of forest cover （potential refuge）, in either the presence or absence of a nearby simulated predation threat （a sharp-shinned hawk Accipiter striatus model）. Compared with the control treatment, we observed proportionally fewer bird visits to the food patch, and the birds took longer to re-emerge from forest refuge and return to feed at the food patch, after the hawk presentation than before it. The observed threat-sensitive latency-to-return response was stronger when the food patch was further away from the nearest refuge. Overall, our results are consistent with the predictions of the threat-sensitive predator avoidance hypothesis in that wild passerine birds （primarily black-capped chickadees Poecile atricapillus） exhibited more intense antipre- dator behavioural responses with increasing level of apparent threat. The birds were thus sensitive to their local perceived threat of predation and traded-off safety from predation （by refuging） and foraging gains in open habitat in a graded, threat-sensitive manner [Current Zoology 60 （6）： 719-728, 2014].
