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   

Guiding Low Spatial Ability Individuals through Visual Cueing: The Dual Importance of Where and When to Look

Research suggests that spatial ability may predict success in complex disciplines including anatomy, where mastery requires a firm understanding of the intricate relationships occurring along the course of veins, arteries, and nerves, as they traverse through and around bones, muscles, and organs. Debate exists on the malleability of spatial ability, and some suggest that spatial ability can be enhanced through training. It is hypothesized that spatial ability can be trained in low-performing individuals through visual guidance. To address this, training was completed through a visual guidance protocol. This protocol was based on eye-movement patterns of high-performing individuals, collected via eye-tracking as they completed an Electronic Mental Rotations Test (EMRT). The effects of guidance were evaluated using 33 individuals with low mental rotation ability, in a counterbalanced crossover design. Individuals were placed in one of two treatment groups (late or early guidance) and completed both a guided, and an unguided EMRT. A third group (no guidance/control) completed two unguided EMRTs. All groups demonstrated an increase in EMRT scores on their second test (P < 0.001); however, an interaction was observed between treatment and test iteration (P = 0.024). The effect of guidance on scores was contingent on when the guidance was applied. When guidance was applied early, scores were significantly greater than expected (P = 0.028). These findings suggest that by guiding individuals with low mental rotation ability “where” to look early in training, better search approaches may be adopted, yielding improvements in spatial reasoning scores. It is proposed that visual guidance may be applied in spatial fields, such as STEMM (science, technology, engineering, mathematics and medicine), surgery, and anatomy to improve student's interpretation of visual content.

Libraries and Spatial Literacy: Toward Next-Generation Education     

Benjamin D. Branch 《College & Undergraduate Libraries》2014,21(1):109-114

The role of the library is to assist citizens in skills development critical to national interest and empowerment as literacy ambassadors, in general. Specifically, the work by the Federal Geographic Data Committee (1994) indicates that spatial literacy is for every citizen and not just a set of workforce specialists. Hence, the use of maps in decision making and problem solving will become fundamental to all professions, including library professionals. Thus, a spatial literacy awareness and rationale for such as standard job ability is discussed as a future librarian workforce proficiency and knowledge transfer medium.  相似文献

中国教育支出与经济增长的空间实证分析   总被引：12，自引：2，他引：12  

顾佳峰 《教育与经济》2007,(1):29-33

本文使用空间计量经济学方法,分析2000年中国各县教育经费支出情况,发现教育经费支出对GDP、地方财政支出和城乡居民储蓄存款余额的弹性较弱,都小于1,因此,瓦格纳法则不适用。在经济高速增长情况下,这种弱弹性限制了“4%”目标的实现。所以,当前除了要关心教育经费短缺问题,更要关心教育经费使用的低效问题。要积极探索提高既定教育投入的产出效率和效益,通过良好而科学的教育产出管理,节约教育投入,提高办学效益,以缓解现有教育投入不足的压力。  相似文献

弧形混凝土结构温度应力计算研究     

黎永索  卫军 《湖南城市学院学报》2003,24(6):10-13

对弧形混凝土结构温度应力的计算研究表明，弧形结构的环向应力沿高度方向基本一致，可以简化为拱单元计算，拱单元的支座约束可以用“等效暗柱”来计算；结构两侧温差对弧形结构的环向应力的影响较轴线温差变化的影响更大，控制温度裂缝主要是控制结构物两侧的温差．通过设置滑动层，减小结构的抗侧移刚度。则弧形混凝土结构可以作无缝设计．  相似文献   

“给予”动词的语义和语用研究   总被引：2，自引：0，他引：2  

徐峰 《华东师范大学学报(哲学社会科学版)》2002,34(2):78-87

给予动词语义上要求携带三个强制性语义成分,不同语域的动词对强制性语义成分在生命度、空间度、动词主体成分与与体成分之间的定向控制关系上有不同要求。不同动词的强制性语义成分映现为句法成分时有完全映现和不完全映现两种映现方式,句式的不同实际上反映了不同的功能要求。不同给予动词的强制性语义成分在省略、移位、变换等语用变化上也有不同特点。  相似文献
