Spatial Discovery of Linked Research Datasets and Documents at a Spatially Enabled Research Library     

Sara Lafia  Werner Kuhn 《Journal of Map & Geography Libraries》2018,14(1):21-39

Current publishing practices in academia tend to result in datasets that are difficult to discover. This is because datasets are not well-integrated across academic domains and they are often not linked to the documents that reference them. For these reasons, discovering datasets across domains can be challenging; for example, discovering archeological observations and biological specimens using the same search is not widely supported, even if both datasets share a similar spatial extent, like Mesoamerica. It is also challenging to retrieve relevant documents that reference datasets; for example, retrieving a series of field reports that reference archeological observations is typically not supported. Our work develops an extensible method for: (1) geographically integrating collections across disciplinary repositories and (2) connecting datasets to related documents. We describe a collection of spatially-referenced researcher datasets, capturing their metadata elements and encoding them as linked open data. We then leverage existing library services to formalize links from datasets to documents. The system described in this work has been deployed, resulting in an experimental open data site for the UCSB campus. Results indicate that this system can be scaled-up with support from an institutional repository in the near future.  相似文献

时间的生长与静止     

blanc  Mona Kuhn 《收藏》2014,(16):86-93

生于巴西的Mona Kuhn 2009年重返故地拍摄Native系列,是一场将人体与风景连为一体,通向一场内在的尤利西斯之旅。此后Kuhn拍摄了新系列Bordeaux,同样将人体与自然风景分离并融合,所有的风景照片则均以黑白呈现,时间在恬静又略带神秘气息的庄园与树林中停滞,成了关于永恒的暗示。时间或许是这一系列的关键,具象的和抽象的,流动的和静止的。  相似文献   

采用EMDR 技术对消极表现经历的情绪再加工     

格来格尔·库恩 《天津体育学院学报》2008,23(3):193-193

许多运动员在他们的职业生涯中都经历过在特定情境中承受反复的身心障碍(如恐惧对手,所谓的"不堪一击",双腿灌铅).原因是频繁的压抑:一种影响比赛的关键动作发挥的神经紧张状态.在很多个案中潜在焦虑过程导致的压抑源于一个消极比赛经验(如比赛中糟糕的一天或一连串糟糕的日子).  相似文献   

A Dialogic Path to Evidence-Based Argumentive Writing     

Laura Hemberger  Deanna Kuhn  Flora Matos  Yuchen Shi 《学习科学杂志》2017,26(4):575-607

Central to argument are evidence-based claims, requiring coordination of a claim with evidence bearing on it. We advocate a dialogic approach to developing argument skills and in the work reported here examine the further scaffold of prompts that exemplify functions of evidence in relation to a claim. This scaffold was successful in accelerating the prevalence of evidence-based claims in essays of low-performing middle schoolers compared to participants in the same year-long dialog-based intervention who received no or a limited form of evidence prompts and compared to previous samples engaged in a nondialogic curriculum. An experimental group achieved a proportion of evidence-based claims above 50% by the end of the year, transferring their newly developing skill from one topic to another. The use of different types of evidence emerged in a sequence corresponding to the cognitive demands they posed. Students first used support-own evidence. They used weaken-other evidence increasingly over time, but the two evidence types inconsistent with their position (support-other and weaken-own) showed lesser and later gains. Supporting a dialogic approach, qualitative data showed that evidence use occurred most readily in dialogs; then in individual writing on the same topic; and to a more limited extent in essays on a new, unstudied topic.  相似文献   

A parallel microfluidic channel fixture fabricated using laser ablated plastic laminates for electrochemical and chemiluminescent biodetection of DNA     

Edwards TL  Harper JC  Polsky R  Lopez DM  Wheeler DR  Allen AC  Brozik SM 《Biomicrofluidics》2011,5(4):44115-4411514

Herein is described the fabrication and use of a plastic multilayer 3-channel microfluidic fixture. Multilayer devices were produced by laser machining of plastic polymethylmethacrylate and polyethyleneterapthalate laminates by ablation. The fixture consisted of an array of nine individually addressable gold or gold/ITO working electrodes, and a resistive platinum heating element. Laser machining of both the fluidic pathways in the plastic laminates, and the stencil masks used for thermal evaporation to form electrode regions on the plastic laminates, enabled rapid and inexpensive implementation of design changes. Electrochemiluminescence reactions in the fixture were achieved and monitored through ITO electrodes. Electroaddressable aryl diazonium chemistry was employed to selectively pattern gold electrodes for electrochemical multianalyte DNA detection from double stranded DNA (dsDNA) samples. Electrochemical detection of dsDNA was achieved by melting of dsDNA molecules in solution with the integrated heater, allowing detection of DNA sequences specific to breast and colorectal cancers with a non-specific binding control. Following detection, the array surface could be renewed via high temperature (95 °C) stripping using the integrated heating element. This versatile and simple method for prototyping devices shows potential for further development of highly integrated, multi-functional bioanalytical devices.  相似文献   

Integrated carbon fiber electrodes within hollow polymer microneedles for transdermal electrochemical sensing     

Miller PR  Gittard SD  Edwards TL  Lopez DM  Xiao X  Wheeler DR  Monteiro-Riviere NA  Brozik SM  Polsky R  Narayan RJ 《Biomicrofluidics》2011,5(1):13415

In this study, carbon fiber electrodes were incorporated within a hollow microneedle array, which was fabricated using a digital micromirror device-based stereolithography instrument. Cell proliferation on the acrylate-based polymer used in microneedle fabrication was examined with human dermal fibroblasts and neonatal human epidermal keratinocytes. Studies involving full-thickness cadaveric porcine skin and trypan blue dye demonstrated that the hollow microneedles remained intact after puncturing the outermost layer of cadaveric porcine skin. The carbon fibers underwent chemical modification in order to enable detection of hydrogen peroxide and ascorbic acid; electrochemical measurements were demonstrated using integrated electrode-hollow microneedle devices.  相似文献   

The Benefits of Using Sociodrama in the Elementary Classroom: Promoting Caring Relationships Among Educators and Students     

Deanna Marie Pecaski McLennan 《Early Childhood Education Journal》2008,35(5):451-456

In the current age of academic rigor, standards and accountability, the fostering of caring relationships in the classroom may not always be a priority. Expressing care for another person is a skill that can be taught and nurtured through a supportive educational environment. Sociodrama encourages each of its participants to develop self-confidence and self-expression through risk-taking and exploration in activities that explore real life personal feelings and situations. By using sociodrama as a means for exploring issues in the classroom it is possible to celebrate participants’ individuality and to create caring and nurturing relationships among educators and students. This article examines the research describing the benefits of including sociodrama in the elementary curriculum.  相似文献
