地理学家的演讲与他们运用文字、图象所作的交流同样值得重视.美国的地理学可以通过下述途径得到加强,即围绕地点、地区和全球联系发展实质性演讲,促进自然地理的发展,恢复地理生态的传统.地理信息系统(geographic information systems)对于完成上述任务,对于改进地理学科以满足不断出现的需要,将是一个非常有用的工具.如果我们能够避免自己拆自己的台,避免不现实的空想,避免玩弄语言技巧,而是坚持在大学里进行高质量的教学,并在教师和从事地理实践工作的人员之间开展学术交流,那么地理学将会变得更加有效.我们有一个前所未有的机会来帮助改进美国的中小学地理教育.  相似文献

移动性是21世纪人文地理的研究热点和重要议题,它体现了空间科学的社会学转向,属于人文地理学的核心概念和中心命题,其中心性突出体现在它与其他传统和新兴的人文地理分支学科的交叉。本文以表格为工具梳理了地理移动性的研究理路,发现移动地理与其他人文地理分支学科共同聚焦的核心是:时间地理、旅游地理、行为地理的“时空行为”问题,政治地理、社会地理的“权力”“平等”“权利”问题,身体地理的“具身实践”“感官体验”问题,情感地理的“地方依恋”“身份认同”问题,想象地理的“地方感”问题,道德地理的“空间道德感”问题。本文识别这些关键问题为移动地理的“核心要素”,搭建移动地理的框架和体系,指出探查这些要素之间相互作用机制和不同时空移动类型的转化机理是未来移动性的研究方向。根据移动的空间尺度和时间强度,构建了包括日常移动、旅游和旅行移动到永久性移动在内的地理学移动性连续轴类型,并探索了移动地理研究的方法论体系。  相似文献

信息社会中博物馆的知识传播职能从被动转向主动,博物馆采用信息技术管理藏品和相关数据,不仅要满足传统业务需求,也要面向网络环境中的使用者。在此过程中,文物藏品信息在互联网环境下的呈现,需要采用标准化的描述元数据方案和受控词汇描述文物的核心信息。该研究首先说明文物数据标准的定义与类型,阐述文物描述元数据的概念与作用,并对比CONA、CDWA Lite、Object ID和第一次全国可移动文物普查的描述元数据方案,说明元数据方案差异反映出的设计需求和结果差异;再进一步对比大英博物馆、大都会博物馆、北京故宫博物院、台北故宫博物院线上文物藏品检索方式,通过检视其检索结果的信息结构与内容,阐述合理的描述元数据方案能呈现丰富信息并导向精准检索。最后建议我国文物博物馆领域应完善文物数据标准,文博机构应制定规范化的文物描述元数据方案和配套实施的编目规则与本地受控词表;文博机构官网在线藏品检索系统应考虑用户需求,呈现完善的编目成果。  相似文献

Monitoring is deemed crucial for the incentivization of a decentralized organization, but its function relies on information transparency between the central authority and the delegated individuals. We test this hypothesis by considering changes in the fiscal behavior of Chinese county governments following an exogenous fiscal reform in 2004/2005 that removed information obstacles between provinces and counties. Employing data on 590 Chinese counties from 2000 to 2009, we find that counties in the reform provinces adopt a more proactive fiscal policy after the reform, suggesting that they become more incentivized in the political competition for economic growth. Such effects are stronger in counties with fewer competing peers and counties with either high or low ranks in the records of economic growth among peers. The increase in counties' productive spending leads to higher economic growth in later years.  相似文献

A review of recent anthropological research deriving behavioral inferences from analyses of human skeletal remains focuses on interpretations of diet, social organization, population structure and migration, activities, activity levels and occupation, and warfare, violence, and death in the prehistoric and historic Americas. Critical evaluation of these inferences shows that some of them suffer from inadequate supporting evidence, lack of consideration of alternative hypotheses, or absence of clear methods for deriving and testing these inferences. Overall, however, the potential for behavioral reconstruction from skeletal analysis is great. Behaviors leaving more direct effects on bone such as dietary preference, warfare, and some activities produced the most secure inferences when derived from populational samples and supported by supplementary evidence. Human skeletal remains represent important resources for the reconstruction of behavior.  相似文献

The investigation of a simple behavior, child naming, can provide insights into the varying reactions of families confronted by the extraordinary war losses of the First World War. The current study analyses names given in a large cohort of French orphans born 1914–1916, constructed thanks to the linkage of civil registers with a nationwide database of soldiers who died during the War. It shows that a prenatal loss of father was associated with a strong increase in father's name transmission. The phenomenon was twice as intense in officers' offspring. Regression analysis suggests the precise timing of the father's death controlled this change in naming behavior: father's name transmission was at a maximum when the father died at the very beginning of pregnancy.  相似文献

The reemergence of cognitive studies in comparative psychology and ethology, coupled with ongoing archaeological discoveries and recent advances in genomics, have contributed to the current explosion of scientific interest in dogs (Canis lupus familiaris). The long and complex evolution of a human-dog relationship is explored from the differing perspectives of ethology, cognitive sciences, evolutionary anthropology, archaeology, and paleoanthropology. Our understanding of dogs is again shedding light on human cognitive evolution and the complex, and at times controversial, process of domestication.  相似文献

The quick and accurate identification of post-earthquake rescue objects can minimize the casualties and property loss caused by earthquakes. With the rapid development of remote sensing technology, rescue objects can be identified through high-resolution remote sensing images. There are two main categories of approaches to identify rescue object through high-resolution images: automatic extraction by a computer and visual judgment by professionals. Although results can be obtained quickly by using automatic extraction, the accuracy of the results is unacceptably low. For visual judgment, the large demands for time and professionals restrict its wide practical application. In this study, we introduce crowdsourcing into the identification of post-earthquake rescue objects. First, we integrate the advantages of the computer and crowdsourcing, which means that the computer takes advantage of the speed of information processing, while crowdsourcing makes full use of human recognition capabilities. Second, we take visual judgment tasks out of the hands of professionals and entrust the tasks to workers in a crowdsourcing platform. Not only are the human resources infinite, but we can also improve the efficiency of identifying rescue objects. Third, we propose a crowdsourcing model that improves the quality of the results and saves human resources. Finally, experimental results demonstrate that our solution is feasible.  相似文献

Voluntary environmental programs (VEPs) have been used as a policy tool in the United States since the early 1990s and come in many forms. Early assessments of VEPs targeting changes in production processes showed that industrial participants improved their environmental performance and VEPs were celebrated as a viable alternative to more traditional regulation. Recent analyses using more sophisticated techniques, however, paint a less favorable picture. On the one hand, firms appear willing to sign up to VEPs, and in some cases, participants may be able to create a shield against future losses in shareholder value. On the other hand, these VEPs targeting production processes appear not to generate significant pollution abatement. The latter finding is particularly disturbing and this article discusses various explanations, including institutional failure and participant motivations. Future research needs to focus on understanding the firm motivation to invest in production‐related pollution abatement under a VEP. For policymakers, the research offers a warning on the limited impact to date of VEPs targeting production processes. However, the multitude of other VEPs, such as those which target new product development and changing market demands, merit a closer look to determine the overall potential of VEPs to engender positive environmental change.  相似文献
