High Res at High Speed: Automated Delivery of High-Resolution Images from Digital Library Collections     

《Journal of Web Librarianship》2013,7(2):109-124

As primary source materials in the library are digitized and made available online, the focus of related library services is shifting to include new and innovative methods of digital delivery via social media, digital storytelling, and community-based and consortial image repositories. Most images on the Web are not of sufficient quality for most media outlets, so what happens when patrons require high-resolution versions of images for use in their print publications or projects? Until recently, patrons at the University of Houston Libraries used a clunky, paper-based request process for high-resolution images that was frustrating for them and time-consuming for staff. The authors of this article outline how an interdepartmental team of University of Houston Libraries staff used Drupal to develop an automated patron request system that is modeled after online shopping cart experiences and integrates with the CONTENTdm-based University of Houston Digital Library. The article provides suggestions for libraries with digital collections about how to create a system that efficiently captures patron requests and streamlines staff delivery of high-resolution files.  相似文献   

Evaluation of a core team centred professional development programme for building a whole-school cooperative problem solving approach to conflict     

Andrew Jonathan White  Elizabeth Freeman  Margot Trinder 《教育心理学》2013,33(2):192-214

This study evaluated a professional learning approach using a core team (CT) model to assist primary (elementary) schools to develop whole-school collaborative conflict resolution processes. Thirteen schools were matched and randomly assigned to the enhancing relationships in school communities programme (n?=?10) or a non-programme control group (n?=?3). Programme schools provided a core (professional learning) team, who attended professional learning days, and disseminated programme content throughout their schools. Programme schools also received one full school staff workshop. After one year, CT participants were more likely to apply a collaborative conflict resolution model to problem scenarios and report greater knowledge and skills compared to non-programme-school control participants. Compared to the non-programme control group, non-core team programme school staff described using more cooperative approaches to handling conflict, especially when they had received more professional development from their CT. Programme school teachers taught more hours conflict resolution curriculum, and increases in hours taught by programme (but not control) teachers were associated with teacher reported increases in student understanding and use of cooperative methods. Patterns also supported a role of self-efficacy in implementation. The potential usefulness of a CT professional learning model for assisting schools to develop cooperative conflict resolution approaches was supported.  相似文献

资源利用冲突解决机制研究     

奉晓政 《资源科学》2008,30(4):540-545

资源能为人类所利用并具有相对稀缺性。在资源利用中,,中突难以避免,尤其近代以来日益突出。目前,我国资源利用冲突主要包括自然资源所有权纠纷、自然资源用益物权纠纷、自然资源污染破坏纠纷等。当前我国资源利用,中突解决途径主要有两大类,即非讼解决方式与诉讼解决方式。非诉讼解决方式具体包括协商、调解、仲裁与行政裁决等替代性纠纷解决方式;诉讼解决方式包括民事诉讼、行政诉讼与刑事诉讼等。我国现有资源利用冲突解决途径都或多或少地存在一些问题。基于此,我们应取采如下措施完善与创新资源利用冲突解决机制：进一步规范资源利用冲突行政调解,明确行政调解效力;建立并完善资源利用冲突仲裁机制,扩大仲裁适用范围;统一资源利用冲突行政裁决立法,确立司法最终原则;改造民事诉讼当事人制度,建立环境资源民事公益诉讼制度;扩大行政诉讼受案范围,建立环境资源行政公益诉讼制度;强化环境资源刑法保护,增设环境资源犯罪新罪名;综合改进与完善纠纷解决途径,建立健全多元化资源纠纷解决机制。  相似文献

词汇歧义消解的认知研究:理论、方法与现状   总被引：4，自引：0，他引：4  

张亚旭  舒华 《北京师范大学学报(社会科学版)》2000,(5)

近２０年来,在词汇歧义消解领域,研究者采用多种技术进行实验,提出了４ 种典型的模型,即多重通过模型、选择通达模型、重排序通过模型和整合模型。到目前 为止,不同的研究之间仍然存在很大分歧。今后的研究应该在考察语境作用时间点的同 时,重点探讨语境影响歧义词意义通达的机制,特别是应该重视对歧义词加工中抑制过 程的探讨  相似文献

高分辨率SAR子孔径图像相干性分析 及其地物分类应用     

邢文继  金燕  仇晓兰  丁赤飚  周晓 《中国科学院大学学报》2022,39(6):764-775

针对相干性这一合成孔径雷达(SAR)图像分析常用的特征量进行分析,首先从理论上分析高分辨率SAR图像中人造目标和自然地物等典型目标的子孔径、子频带以及不同子孔径重轨干涉图像间的相干系数,然后利用高分辨率星载SAR实际数据开展上述相干系数的计算,验证分析的正确性。随后根据不同地物在不同维度相干系数上体现的不同特点,进行非监督地物分类,并给出不同类别所表征的地物特点。分析结果可为高分辨率SAR数据的优化应用提供支撑,并可加深对SAR不同地物目标特性的理解。  相似文献
