改进的熵值法在河南省可持续发展能力评估中的应用   总被引：81，自引：0，他引：81  

乔家君  乔家君 《资源科学》2004,26(1):113-119

首先从系统功能角度设计了河南省可持续发展的指标体系,包括7个功能组71个指标,接着评述了熵值法的基本原理、运算步骤及对该方法的改进措施,并用改进的熵值法对河南省可持续发展能力及其结构做了定量分析.河南省可持续发展指标权重值≥0.015的指标有:经济指标7个、环境指标6个、人口指标6个、社会指标5个、资源指标4个、科技指标1个,累计权重依次为0.120、0.118、0.108、0.085、0.066、0.020.表明河南省可持续发展系统的构成要素中,经济因子最为重要,其次为环境因子,再次为人口因子.提高河南省可持续发展能力首先要大力发展生产力,同时要保证生态环境的不退化,另外也要控制人口数量的增长.20世纪90年代河南省可持续发展能力总趋势是增强的,但1991年～1993年间呈下降态势.在河南省可持续发展系统功能中,区域发展水平对系统的贡献最大,起着决定性作用.  相似文献   

财政补贴、代理问题与企业技术创新——基于R&D投资异质性视角     

顾群  谷靖  吴宗耀 《软科学》2016,(7):70-73

利用深圳证券交易所2008~2013年上市高新技术企业的数据,基于第二类委托代理问题,研究政府财政补贴对创新投入与创新模式的影响。研究结果显示:财政补贴对高新技术企业的创新投入具有正向促进作用;财政补贴对创新模式的影响存在差异,即财政补贴对探索式创新有激励作用,而对开发式创新没有作用;控制权私有收益对财政补贴与创新投入之间有负向调节作用;控制权私有收益对财政补贴与探索式创新产生正向调节作用,而控制权私有收益对财政补贴与开发式创新之间的关系不起作用。  相似文献   

虚拟多角化的合作机制与运作模式探析   总被引：1，自引：0，他引：1  

项保华  叶永玲 《科研管理》2003,24(4):82-86

虚拟多角化是以功能为介体通过非产权合作联系到一起的运作整体。本文在对虚拟多角化的内涵与特征分析的基础上，探讨了虚拟多角化的合作代理、自私代理合作机制，进而提出了虚拟多角化的“哑铃型”与“联合体”两种运作模式及其对应的具体运作形式，最后阐述了虚拟多角化对家电业和轻纺业的实践启示。  相似文献   

新一代的netfilter网络底层开发结构     

张金良  李中言 《现代情报》2005,25(9):43-45

Linux的网络安全模块到最新的共有3个版本：ipfwadm，IPCHAINS，netfilter。只要是使用和研究过这三代网络安全模块的用户就能深刘的体会到Linux系统中网络安全的进步和Linux内核版本号的变迁一样迅速。Linux内棱级的网络安全越来越完善、越来越合理、越来越易于更多的人参与进行二次开发。尤其是最后一点最为重要，一个难于扩展的框架在Linux这样一个开放源代码的空间里，无疑是暴殄天物。在原有的IPCHAINS框架中也有诸多的不合理和不明智的设计。本文将详细的描述IPCHAINS的不足与缺陷，详尽的介绍netfilter的整体框架。  相似文献   

松嫩平原农区的经济出路──以黑龙江省双城市东新村为例     

康庆禹 《资源科学》1994,(5)

我国北方平原农区素以生产粮豆为主，经营十分单一，由于生产成本提高而粮豆价格偏低等诸多因素，农民长期收入水平低下。在市场经济条件下，平原农区的经济出路何在？本文通过典型实例调查，从平原农区的资源特点出发，认为“粮、多、企”协调发展是平原农区经济的可行出路，并提出了这种发展模式的改进途径。  相似文献   

Cartesian and corporeal agency: women’s studies students’ reflections on body experience     

Satu Liimakka 《Gender and education》2011,23(7):811-823

This article explores young women’s agency in relation to the body and the possible role of women’s studies in interpreting body experiences and constructing agency. The article is based on written accounts of one’s body experience written by Finnish students of women’s studies. The young women’s accounts manifested two types of agency: the accounts on agency relating to the body focused around attempts of resistance to cultural body ideals and conventional heterosexual roles. This ideal subjectivity relies on an individualistic and Cartesian understanding of agency, emphasising the young woman’s independence from culture, other people and her own body. The accounts on agency within the body expressed experiences of overcoming the mind/body dichotomy and connecting bodily to the surrounding world. I suggest that a shift from the implicit curriculum of Cartesian agency to a curriculum of corporeal agency could prove useful in educational contexts.  相似文献   

‘Hope in failure’: A Level students,discursive agency,post-feminism and feminism     

Carol A. Taylor 《Gender and education》2011,23(7):825-841

This article begins with Pollock’s comment that Judith Butler ‘finds hope in failure’ and its aim is to explore what ‘hope in failure’ means in relation to A Level students’ engagements with post-feminism and feminism. The article grounds its argument in an exploration of how post-feminism and feminism intersect with sixth form students’ subjectivities through the educational practices of their second-year A Level subject-based research. The article analyses empirical instances of students’ discursive agency through Butler’s notions of performativity, citationality, excessive signification and resignification to consider the complex, multiple and creative ways in which sixth form students produce themselves as viable gendered subjects in relation to post-feminist and feminist discourses. The analysis considers both how discourse regulates and conditions students’ relations with post-feminism and feminism and how discourse contains the possibilities for the subject to refuse the refusal of feminism in popular culture. Through its analysis of how students use their discursive agency to claim a feminist identity, and how these uses constitute transgressive practices, the article explores the political significance of identifications with feminism in doing gender differently. It ends with an argument for the re-consideration of the apparently assured popular cultural ‘failure’ of feminism in post-feminist neoliberal times.  相似文献   

Supporting minority students through a reflexive approach to empowerment     

Amanda Keddie 《British Journal of Sociology of Education》2011,32(2):221-238

Referring to the experiences of three Muslim refugee girls recently settled in Australia, this paper examines issues of schooling and empowerment. The paper draws on teacher and student interview data from a study that investigated inclusive approaches to addressing issues of cultural diversity in a secondary state high school in Queensland. The paper foregrounds the girls’ highly positive views of their experiences at the school; views that reflect the girls’ access to spaces of empowerment but belie the complexity and tensions involved in how empowerment was understood and approached by educators at the school. Theorising empowerment through poststructural understandings of agency, the paper examines conditions and ways of understanding that make possible spaces of empowerment for the girls. In particular, the paper argues for a reflexive approach to empowerment that is informed by an understanding of the framing discourses shaping minority student identity and a critical reflection on educator and school positionality.  相似文献   

区域“数字鸿沟”形成原因分析   总被引：1，自引：0，他引：1  

薛伟贤  刘骏 《图书馆建设》2011,(1):6-10

区域"数字鸿沟"在全球普遍存在,严重影响了和谐世界的建立,要想从根本上弥合区域"数字鸿沟"就必须分析其形成原因。信息资源的差距和信息技术使用技能的差距是区域"数字鸿沟"形成的直接原因,二者分别从"信息拥有"和"信息使用"方面发挥作用;经济发展水平的差距、政府相关政策的差异和社会文化的差异是区域"数字鸿沟"形成的间接原因,分别从"信息化需求"、"信息化环境"、"信息化意识"方面发挥作用。这5种原因以特定结构系统地结合起来,最终导致区域"数字鸿沟"的形成。  相似文献   

日本共享知识库的调查与分析     

陈雨杏 《图书与情报》2011,(1):25-30

对于那些难以构建自身独立机构知识库的中小规模的学术机构来说,共享知识库的构建更显经济和有效。文章对日本共享知识库的基本情况、成员机构、经费来源、内容建设等进行了调查和分析。调查结果发现,日本的共享知识库的发展得益于日本国立情报学研究所的经费投入和技术支持,主办机构构建自身独立知识库的经验等等。同时,也发现了日本共享知识库一些问题或不足。  相似文献
