The Terra Populus project (TerraPop) addresses a variety of data management, curation, and preservation challenges with respect to spatiotemporal population and environmental data. In this article, we describe our approaches to these challenges, with a particular focus on geospatial data workflows and associated provenance metadata. The goal of TerraPop is to enable research, learning, and policy analysis by providing integrated spatiotemporal data describing people and their environment. To do so, TerraPop is assembling a globe-spanning and temporally extensive collection of high-quality population and environmental data, ensuring good documentation, and developing a Web-based data access system that enables users to assemble customized integrated data sets drawing on a variety of data sources and formats. We describe TerraPop's collection strategies, detail the geospatial workflows involved in preparing data for ingest into the project database and those used to transform data across formats for dissemination, and discuss the system used to capture and manage provenance metadata throughout the project. A key aspect of the project is the development of global current and historical administrative unit boundaries that can be linked to census data. These boundaries serve as the linchpin of TerraPop's data integration strategy, and constitute an important data set in their own right. 相似文献

The problems in making machine-readable data files (MRDFs) accessible as well as in using them are basically the same for all social scientists. There are two kinds of problem: the quality of the data in the MRDFs themselves and accessibility. The social scientists' concern is quality control; the librarians' is accessibility. "Clean" datasets make it possible to ask questions that could not be asked in the past. In analyzing large amounts of data, social scientists can detect the "weak signals" of important relationships. Three problems confronting librarians are: availability of bibliographic control; the quality of documentation; and level of user skills. 相似文献

科研人员是从事科普活动的重要力量,然而目前国内鲜有研究聚焦科研人员参与科普活动的实施效果。本研究以上海自然博物馆“与科学家面对面”科普活动的效果评估为案例,通过对参与活动的观众进行无干扰跟踪观察和活动后的访谈,以探究科研人员在科普活动中对观众体验的直接价值与潜在影响。结果表明,科研人员介入科普活动,不仅对观众认知能力及其对科研工作的认同感有积极影响,而且科研人员面对公众的交流能力也有显著提升。但是,科研人员在科普经验上的欠缺也成为制约活动效果的潜在因素。研究结果将为科研人员参与的科普教育活动的策划和实施提供参考。 相似文献

This work analyses the perception and practice of sharing, reusing, and facilitating access to research data in the field of food science and technology. The study involved the coordination of a focus group discussion and an online survey, to understand and evince the behaviour of researchers regarding data management in that field. Both the discussion group and the survey were performed with researchers from several institutes of the Spanish National Research Council. The lack of a data sharing culture, the fear of being scooped, and confusion between the concepts of the working plan and the data management plan were some of the issues that emerged in the focus group. Respondents' previous experience with sharing their research data has been mainly in the form of appendices to peer‐reviewed publications. From the survey (101 responses), the most important motivations for publishing research data were found to be facilitating the reproducibility of the research, increasing the likelihood of citations of the article, and compliance with funding body mandates. Legal constraints, intellectual property, data ownership, data rights, potential commercial exploitation, and misuse of data were the main barriers to publishing data as open data. Citation in publications, certification, compliance with standards, and the reputation of the data providers were the most relevant factors affecting the use of other researchers' data. Being recent or recently updated, well documented, with quality metadata and ease of access were the most valued attributes of open research data. 相似文献

In the last decade, two online archaeology data repositories, Digital Antiquity's The Digital Archeological Record (tDAR) and the Alexandria Archive Institute's (AAI) Open Context, have emerged in the United States as key players in the development of technology and Web platforms for preservation and public online access to archaeological research data. The need for these services has intensified since 2011, in the wake of U.S. federal open access mandates and funding agency data management plan requirements for grant applications. Through a comparison of selected features of tDAR and Open Context, this article highlights similarities and key differences in their designs, data management policies, and practices, and provides guidance to subject specialist librarians and others who advise archaeological researchers about how these differences can impact the suitability of each repository for specific data characteristics. 相似文献

This study intends to uncover the mentorship effect by investigating the impact of mentors’ academic titles and research performance on the academic success of young scientists. Drawing on the data of chemical scientists from China's 985 project universities, we demonstrate that the probability of young scientists acquiring academic success increases if their mentors are qualified Chinese Academy of Sciences (CAS) or Chinese Academy of Engineering (CAE) academicians. However, this positive effect may be insignificant or negative for improved academic performance. Additionally, the role of the mentors’ research performance in moderating the relationship between the young scientists' research performance and the probability of acquiring an academic title is not significant and may even be negative. Remarkably, our empirical results suggest that mentors with a CAS or CAE academician title and an increase of the young scientists’ H-index by 20 have equal effects on the probability that young scientists win an Excellent title. This raises concerns about the mentorship effect in China. The results have solid practical implications that are clarified at the end of this research. 相似文献
