Piece-by-Piece Review of Digitize-and-Lend Projects through the Lens of Copyright and Fair Use     

Michelle M. Wu 《Legal Reference Services Quarterly》2017,36(2):51-73

Digitize-and-lend library projects can benefit societies in multiple ways, from providing information to people in remote areas or with physical disabilities to facilitating the sharing of library resources with information-poor communities. This article explores the potential of digitize and lend as well as outlines how projects can be undertaken in a manner respectful of the balance of copyright.  相似文献   

Heritage education in the Primary School Standard Curriculum of Malaysia     

《Teaching and Teacher Education》2017

Due to the importance of education for sustainable heritage preservation, it is imperative to pay attention to how heritage is taught in the education system. As a multicultural country with a rich cultural heritage, Malaysia is home to four world heritage sites. This paper investigates Malaysia's new primary school curriculum to determine to what extent the core curriculum cultivates an awareness of and sense of respect for heritage. The results reveal a focus on Malaysian intangible cultural heritage in some core subjects, such as history, Bahasa Malaysia, art, and music education.  相似文献   

基于相对全变分的复杂背景SAR图像舰船尾迹检测     

杨国铮  禹晶  孙卫东 《中国科学院大学学报》2017,34(6):734-742

SAR图像舰船尾迹检测不仅能够反演运动舰船的航速航向信息，也有助于发现图像中弱小的舰船目标。现有的舰船尾迹检测方法对于简单背景SAR图像的检测效果较好，但复杂背景下的检测效果难以满足使用要求。提出一种基于能量泛函极小化的复杂背景SAR图像舰船尾迹检测方法。该方法采用相对全变分技术将图像分解为包含舰船尾迹的光滑成分和海背景纹理成分，通过剪切波变换高频系数重构增强光滑成分，再通过Radon变换检测光滑成分中的尾迹线。比对实验结果表明，本文所提方法对于复杂背景SAR图像的舰船尾迹检测效果明显优于现有的方法。  相似文献   

基于VxWorks的微小型AUV体系结构设计     

聂建多  褚振忠  朱大奇 《上海海事大学学报》2016,37(3):90-94

为提高自主式水下机器人(Autonomous Underwater Vehicle,AUV)控制系统的鲁棒性，将分层递阶结构与包容式结构相结合，提出了一种混合式控制体系结构，开发了基于VxWorks的微小型AUV控制系统.该系统以“海事金枪鱼”号AUV为载体，以嵌入式PC104计算机为系统核心,通过传感器的信息融合、算法实现和多任务运行，控制系统驱动推进器、舵、翼等执行单元实现AUV的姿态调整、导航和路径规划，最终达到自主作业的目的.“海事金枪鱼”号AUV的开发应用，验证了方案的可行性以及控制系统的可靠性和稳定性.  相似文献   

Modern health worries in Pakistani immigrant women in Oslo,Norway     

《Int J Intercult Relat》2020

BackgroundThe main study objective was to investigate modern health worries (MHW) in a group of Pakistani immigrant women in Norway, and to compare it with a group of ethnic Norwegian women. A further aim was to examine differences in MHW with level of education and acculturation in this immigrant group.MethodsThe Pakistani women (N = 101) completed a questionnaire to assess MHW and sociodemographic variables. MHW data were obtained via telephone interviews for the subsample of Norwegian women (N = 344).ResultsThe Pakistani women generally showed lower levels of MHW than did the ethnic Norwegian women. However, when stratified on education, the difference was mainly apparent in the low and middle educational groups. The Pakistani women with high levels of education tended to report higher levels of MHW than those with lower education levels. They reported significantly higher levels of worries about avian flu, radiation from computer screens, and vaccination programmes than did the ethnic Norwegian women on the same high educational level. Their different degrees of acculturation in the Norwegian society appeared to influence their levels of MHW, as the assimilated women showed the highest levels of MHW, whereas the separated women showed the lowest levels.ConclusionsThe group of Pakistani immigrant women was very heterogeneous in terms of MHW, and health authorities and health care workers should therefor adapt health and risk information according to different levels of integration and education.  相似文献   

乒乓球运动员以预防损伤为主的功能训练          下载免费PDF全文

李男  叶晶龙 《体育科研》2019,(5):95-98

功能训练的理念来源于康复领域，现已逐步应用到运动训练中。由于乒乓球运动的项目特征，乒乓球运动员肩关节、腰椎关节、膝关节、踝关节、腕关节等部位容易出现运动损伤。通过对乒乓球运动员常出现的功能问题进行分析，寻找存在的常见问题，进而提出相应的功能训练建议。乒乓球运动员可根据情况，增加改善肩关节、胸椎关节、髋关节、踝关节的活动范围的训练，提高肩胛骨、核心和下肢稳定性的训练，以及改善肩袖、躯干肌力不平衡的训练，通过针对性的功能训练有效减少乒乓球运动员损伤的发生。  相似文献   

安全情报概念的由来、演进趋势及涵义——来自安全科学学理角度的思辨     

王秉  吴超 《图书情报工作》2019,63(3):45-53

[目的/意义]安全问题是当前国家、政府、企业、社会、大众及学界广泛关注的一个重要现实问题，而安全情报是保障安全的必用之宝，故安全情报研究具有十分重要的理论与现实意义。[方法/过程]运用文献分析法和思辨法，从安全科学学理角度出发，论证基于安全科学视角解读与界定安全情报概念的必要性、重要性与紧迫性，探讨安全情报概念的由来与演进趋势，并分析安全情报的涵义。[结果/结论]从安全科学学理角度看，从安全信息到安全情报的安全管理新认识是提出安全情报概念的根本动力，安全情报概念的总体演进趋势是从分散到统一。同时，从系统安全学角度看，安全情报是指所有影响系统安全行为的安全信息。  相似文献

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
