This essay reviews the discipline-connecting potential of experimentation. Two examples are used to illustrate how researchers in the first half of the twentieth century profitably combined resources from different disciplines in their experiments. These experiments were designed to test mechanism models describing chemical processes underlying the behavior of biological systems. The researchers had clear expectations about how certain interventions should affect the behavior of the organisms studied, if that behavior was indeed based on the presumed chemical processes. They manipulated the organisms in the relevant ways and determined how the behavior of the organisms changed as a result.  相似文献

In the introduction to his Spalt und Fuge, Hans-Jörg Rheinberger points to the possibility that we are currently experiencing a new turning point regarding forms of experimentation, which is characterized by the growing importance of high-throughput methods and big data analytics. This essay will explore the thesis that data-intensive research indeed constitutes a form of post-experimental research by interrogating research practices in precision medicine. Section 1 will introduce this thesis and highlight salient features of precision medicine as an example of post-experimental research. Section 2 suggests approach as a category that is broader than experimental system, as discussed by Rheinberger, and can serve to analyze and compare diverse forms of research, including experimental and post-experimental practices. The essay concludes with a reflection on how categories developed for the historiography of recent science might require an update when the science or its context changes (section 3).  相似文献

大遗址保护规划是系统统筹大遗址保护的综合性管理手段和政策纲领,具有系统整体性、综合协调性、战略引导性、控制约束性等特点。大遗址保护规划的对象是大遗址系统及其保护、利用、管理与发展等使用方式,决定了保护规划的愿景目标、架构体系及统筹协调的内容和行动计划。大遗址保护规划的基本理路是以物为基础、以人为中心,以保证大遗址安全为底线,以重塑大遗址空间保护格局、优化大遗址使用方式、推动大遗址资源资产保值增值为使命任务,通过科学合理的遗址资源配置和空间优化,实现大遗址资源与人、自然资源及其他人文资源的共融共生,大遗址保护利益与区域发展利益的和谐统一。  相似文献

本文运用科学计量法与文献研究法,对我国地理学界关于跨国投资的研究进行了综述,发现我国学界在投资时空演变格局、区位选择、驱动因素与效应等方向取得了较为显著的进展,近年来研究的国际化趋势明显。目前中国已经从单纯的外资输入发展为引进与输出结合的双向投资结构,中国的对外投资是近 10年近年的热门话题。 总体而言,相关研究以实证分析为主,经历了从单一理论的借鉴到多理论的整合,视角更多元、内容更多样、方法更综合。空间视角下的计量分析方法和可视化表达是当前跨国投资研究较为热门的方法。未来的研究仍需理论创新,对西方主导的研究视角进行批判性思考,突出地理学科特色。  相似文献

旅游目的地活力在开发规划与营销实践中已被广泛采纳,但其组成内核、形成机理却仍未可知。本文在对旅游目的地活力作为系统整体进行认识的基础上,从旅游者视角,以网络游记文本与深度访谈为资料来源,基于扎根理论的方法探索旅游目的地活力认知过程及影响因素。结果发现,通行衔接与吸引物构成了旅游目的地活力的基本组成要素,两者也是体验反馈的前驱要素,体验反馈是旅游目的地活力认知过程中的后效要素,社会性是传递基本组成要素到体验反馈的关键途径。此外,旅游目的地活力的认知过程还受到自然因素、人文因素、管理因素和发展水平因素的影响,且不同因素的影响效应各有不同。  相似文献

THE "CREATIVE CLASS" IN THE UK: AN INITIAL ANALYSIS   总被引:1,自引:0,他引:1  
Richard Florida argues that regional economic outcomes are tied to the underlying conditions that facilitate creativity and diversity. Thus the Creative Class thesis suggests that the ability to attract creativity and to be open to diverse groups of people of different ethnic, racial and lifestyle groups provides distinct advantages to regions in generating innovations, growing and attracting high‐technology industries, and spurring economic growth. In this paper we investigate the extent to which there might be similar processes concerning the relationship between creativity, human capital, and high‐technology industries at work in the UK as in North America. The approach taken is broadly sympathetic to the Creative Class thesis; critical perspectives and reservations from the literature are introduced as appropriate research is focused around the three principal research questions: Where is the creative class located in the UK? What is the impact of quality of place upon this dispersion? What is the connection between the location of the creative class and inequalities in technical and economic outcomes within the UK? To this end, the creative class and its subgroups are defined and identified. We then construct quality of place indicators relating to tolerance, diversity, creativity and cultural opportunity. To these are added measures of public provision and social cohesion. Data are analysed by means of correlations and regression. In general we find that, although the distribution of the creative class is uneven and complex, our results are consistent with the findings of the North American research with the notable exception of technology‐based employment growth. Finally, priorities for further research are discussed. The need to further investigate causality, variations within the creative class itself, and the potential role of qualitative data in this are highlighted, as is the potential fate of “non‐creative” workers and places.  相似文献

The purpose of this paper is to present, analyse and critique a research method, ‘place mapping’, used to document and understand teenagers' experience, use and perception of public spaces. Researchers in two case study sites, Edinburgh, Scotland, and Sacramento, CA, employed conventional street maps as a basis for eliciting and recording young people's spatial experiences. This method offers an effective mechanism for generating and structuring discussion – through dialogue – by the participants about their dynamic and shared experience of place, geographically recording places and ensuring equitable participation.  相似文献

Recently, attempts have been made to advance our ways of thinking and doing Children's Geographies. This paper contributes to that endeavour in two respects. Firstly it considers how the concept of heterogeneous (or hybrid) geographies may offer a new framework for the study of childhood. Secondly, and more substantively, it explores how ‘non-representational’ ideas and approaches – concerned with the non-cognitive and the profoundly practical – may be employed to inform our empirical engagements within this new theoretical framework.  相似文献
