基于专利引用跨越度计量的两国间间接创新合作机会发现     

李睿  青杨媚  范九江 《图书情报工作》2021,64(23):31-39

[目的/意义] 两个国家间的创新合作机会有些是显性直接的，有些是潜在间接的。在此试图构建一种计量和分析专利引用关系的方法，用于发现两国间潜在的间接创新合作机会。[方法/过程] 全球价值链上不同环节专利之间的引用关系中，蕴含着相互衔接、配套的间接合作关系，而不同环节的专利通常具有不同的功能，即IPC存在一定跨越度。因此，设计"专利引用跨越度"指标及算法，用于计量和筛选专利引用网络中"引用跨越度"达到预设阈值的专利引用关系，作为发现间接创新合作机会的基础数据。以新加坡在中国获得授权的发明专利为样本，基于专利引用跨越度计量并配合人工解读和识别，发现中新两国间一系列的间接创新合作机会。[结果/结论] 基于专利引用跨越度计量的两国间间接创新合作机会发现的方法，被实验检验为有效。  相似文献   

From the body to the city: participatory action research with social cartography for transformative education and global citizenship     

Monique Leivas 《Educational Action Research》2019,27(1):40-56

ABSTRACT

In times of globalization we are facing a crisis of care. The invisibility of relations of domination and oppression against nature, women and girls, as well as the elderly, generate inequalities and structural problems that increase the unsustainability of life on the planet. The uncertainty towards the future, generated by climate change, pollution and scarcity of water resources, is leading us towards war or revolution – a revolution that requires the involvement of the new generations to transform reality and confront contemporary problems. In this sense, it is necessary to educate, raise awareness and empower girls and boys in citizen participation, in overcoming gender inequalities and in the development of fairer and more sustainable practices and behaviours. The participatory action-research experience with social cartography ‘From the Body to the City’, promoted by the Institute of Innovation and Knowledge Management – INGENIO (CSIC-UPV) in collaboration with the primary school CEIP Vicente Gaos of Valencia (Spain), developed together with the students of 4th primary grade, intended to reflect and act collectively on our territories from the principles of transformative education and global citizenship.  相似文献

大面积建成区建筑密度遥感制图产品的精度验证     

王帅  覃驭楚  杨富坤 《中国科学院大学学报》2020,37(1):83-92

大面积建成区建筑密度遥感制图产品能够提供土地开发强度与人类居住环境的基础信息，是支撑人居环境研究和土地利用规划的重要数据。全球人类居住区层（global human settlement layer，GHSL）是由欧盟联合研究中心负责的大面积人居环境制图项目，建成区建筑密度遥感制图产品是GHSL重要的组成部分。目前该产品在欧美地区已经完成了GHSL建成区建筑密度遥感制图产品的验证。然而以中国为代表的东亚区域的建筑物形态和城市布局与欧美等区域有较大的差别，有必要在亚洲地区对其进一步验证。以中国的5个典型城市（上海、西安、长春、昆明和乌鲁木齐）大面积单体建筑物分布图为基础，通过聚合分析和邻域关键点搜寻匹配等算法，生成中国建成区建筑密度栅格图像产品作为验证数据，然后通过回归分析等方法，在像元尺度上对GHSL建成区遥感制图产品进行评价验证。结果显示，GHSL建成区建筑密度产品在较低分辨率下可以反映中国地区建筑密度情况，但在较高分辨率下在高值区过高估计密度。本研究可以为中国地区研发建成区建筑面积密度产品提供依据。  相似文献   

Best of both worlds or refusal to comply? The rich kids of Tehran on Instagram     

Laura P. B. Partain 《Journal of International and Intercultural Communication》2020,13(3):216-237

ABSTRACT

This article offers a textual analysis and semiotic reading of the Rich Kids of Tehran's (RKOT’s) Instagram page. Contributing to scholarship on Iranian youth media practices, this article interrogates how the RKOT navigate urban and rural space to engage in everyday processes of resistance against global and local systemic oppression. Grounding their visual representations on Instagram in historical and cultural context, the author questions how and when quotidian actions are transformed into political transgressions when posted on social media. This article emphasizes the RKOT's agency in shaping their brand by analyzing representations of gender performance, intertextuality, and national identity on Instagram.  相似文献   

射箭全球史试探:丝绸之路考古所见两种角弓考释     

贠琰  陈雨石  郝勤 《武汉体育学院学报》2020,54(4):67-73

综合运用文献研究与考古文物资料分析相结合的方法,辅以射箭运动的基本训练学规律与传统弓箭制作之田野实证,对新疆地区两种出土角弓进行考释。得出如下结论:弓弰翻卷的连弧蛇形角弓是斯基泰人基于骑马游牧的传统、野兽崇拜的心理、便利的北山羊角取材,在继承了亚述三角弓“翻卷的弓弰”设计理念后的革故鼎新;弓渊宽阔,弓弣微凹的插接型长弰角弓起源于公元前2世纪的帕提亚帝国。随着丝绸之路的贯通,交流频度与交流速度的激增使该器形迅速为整个欧亚大陆的民族所复刻。其中,中华文明赋予了其最重要的文化内涵,使原本用于战争的武器有了超越物态的“礼”的象征意义。  相似文献

李广建  陈瑜 《图书情报工作》2019,63(1):41-51

[目的/意义]人类社会在从信息社会向后信息时代过渡的进程中，正在经历从"信息"向"智能"的跨越。在大数据环境和人工智能技术发展的双重因素作用下，知识融合作为知识化和智能化过程中的关键环节，为完善知识服务、智慧服务、催生高级智能形态提供了重要的理论和技术支撑。开展基于全学科视角的知识融合调研，扩展知识融合研究视域，为全面阐释知识融合研究现状，构建统一的知识融合理论研究框架提供借鉴。[方法/过程]本文采用定量与定性结合的文献分析方法，分析不同学科视角下知识融合研究现状，归纳知识融合在不同学科中的主要研究内容和关注的问题、知识融合涉及到的因素、知识融合的应用场景等。[结果/结论]知识融合研究属于多交叉学科领域，概念边界模糊，研究领域分散，目前尚未形成统一的研究框架。本文通过文献调研，在充分总结既往知识融合研究成果的基础上，划分知识融合的研究取向，为知识融合研究提出合理建议。  相似文献   

Actions for sociopolitical consciousness in a high school science class: A case study of ninth grade class with predominantly indigenous students     

Bhaskar Upadhyay  Erin Atwood  Baliram Tharu 《科学教学研究杂志》2020,57(7):1119-1147

This case study explores how a group of Grade 9 students engaged in sociopolitical discourses and actions in a science class in a mostly indigenous student school in Nepal. The study used sociopolitical consciousness (SPC) as a framework to document and understand indigenous students’ SPC-oriented science interactions and subsequent social change actions. We used ethnographic methods of data collection over 6 months. The study focused on the actions of 4 girls and 2 boys belonging to the indigenous Tharu group. Data were analyzed using iterative qualitative methods. The study findings show that students are capable of engaging in critical thinking, critical reflecting, and taking actions for social change. Additionally, students are competent to link their experiences with social, structural, and political discrimination to the relevant science content they learn. The study presents four thematic findings related to SPC and science teaching and learning: Fostering social justice awareness in science class, fostering structural understanding of inequities in sickle cell disease, fostering sociopolitical actions for sickle cell disease, and the teacher's activist pedagogy for SPC in science learning. Implications of the study are that culturally relevant pedagogy helps indigenous students to become sociopolitically more aware of the links between science and social change. Adding aspects of critical pedagogies in science teaching could encourage students to become more sociopolitically reflective about science learning.  相似文献   

Bridging (Identification) divides: Ethnic minority endorsement of new diversity ideologies     

《Int J Intercult Relat》2021

In culturally diverse societies, ethnic minorities are faced with the challenge of negotiating between their national and ethnic identification. Diversity ideologies address this challenge in different ways, by prioritizing national identification in the case of assimilation, and ethnic identification in the case of multiculturalism. However, existing research has highlighted the risks and drawbacks of both ideologies, presenting polyculturalism and interculturalism as new alternatives which construe identities as more complex, dynamic, and interconnected between groups. Given that little is known about these ideologies from the minority perspective, the present study investigated their endorsement among ethnic minorities, as well as associations with their ethnic and national identification in the USA. Results show that, in general, pro-diversity ideologies (multiculturalism, interculturalism, and polyculturalism) are all supported by ethnic minorities, in contrast to assimilation. Moreover, ethnic identification is associated with support for multiculturalism, national identification is associated with support for assimilation, and both are associated with polyculturalism. For interculturalism, associations with ethnic and national identification depend on its subcomponents, which seem to address and bring together the other three ideologies. Interculturalism may therefore be a promising way forward to minimize the risks of assimilation, multiculturalism, and polyculturalism, while also maximizing their benefits to minorities and societies at large.  相似文献
