产品品牌数量对产业集群影响的实证研究——以中国服装产业集群为例

产品品牌作为影响产业集群发展的非标准化特征要素,是内生变量.选择24个服装产业集聚地作为样本,考察集群内产品品牌数量对产业集群发展的影响,发现产品品牌数量对集群的增长和竞争力的提升具有正向作用;然而,进一步研究显示,过多的产品品牌数量也会制约产业集群的发展.最后,对变量进行重新组合后发现,目前中国服装产业集群还处于初级阶段,品牌数量仍旧低于临界值,在品牌培育上需要长期持续不断地付出.

Managing NCEA assessment practice more effectively

The National Certificate of Educational Achievement (NCEA), introduced early this decade, is the national qualification for New Zealand senior secondary school students. Commencing with Level 1 in 2002, the implementation of NCEA represented a marked change from previous norm-referenced-based qualifications and required a considerable paradigm shift in teacher assessment practice. During the transition period, learner needs often took second place to assessment in geography classrooms. This paper identifies the practices that Year 11 geography teachers used post NCEA implementation to manage assessment practice more effectively and to address the perceived over-emphasis on assessment.     

“十四五”时期广东培育海洋创新型产业集群路径初探——基于欧洲经验启示

广东作为我国第一海洋经济大省,重点布局了海洋电子信息等海洋六大产业,目标打造2～3个产值千亿元级产业集群。文章以欧洲107个海洋创新型产业集群为研究对象,梳理其海洋产业前沿交叉领域布局,分析产业集群空间分布特征,探讨产业集群的先进组织管理模式。结果表明,欧洲海洋创新型产业集群以可持续蓝色增长为发展主线,空间分布均衡且实行错位分工协同发展,通过系统建立大量产业集群促进机构和监管体系,构建国际战略集群伙伴关系,引导集群的良性发展。在此基础上,从合作对象、组织机构、交流合作、资金激励和监管体系等角度提出了广东培育海洋创新型产业集群相关建议。     

遥感科学与技术专业本科创新人才培养能力评价体系

通过调查走访,设计、分发、回收纸质、电子问卷,查阅期刊等调查方式收集与遥感科学与技术专业本科创新人才培养能力相关的评价项,将出现次数大于总次数10%的评价项作为最终的专业创新人才培养能力评价指标;根据评价指标含义确定各二级指标对应的评价依据,构建了新时期遥感科学与技术专业本科创新人才培养能力评价体系。该体系可用于遥感科学与技术专业本科创新人才培养能力现状的评价,为后期高校从多方面提高创新人才培养能力提供基础。

关于矿床学创新问题的探讨

为保证矿产资源的持续供应和国家资源安全,需要加强矿床研究以指导矿产勘查的重大突破。在简要回顾矿床学百年发展历史的基础上,初步概括了矿床学开拓创新的基本条件,包括:①矿业发展是推动矿床学发展的原动力;②地学的整体发展为矿床研究提供了基础;③新技术装备提高了发现和创新的能力;④科学的思维方法;⑤个人创造和几代人的共同努力。针对国家需求、学科发展前缘和中国矿床特色相结合的原则,提出了重大地质事件与大规模成矿,深部过程、浅表环境与成矿作用等需要深入研究的10个矿床学科学问题。最后提出了改进矿床学研究的6点意见和建议,强调矿床研究要主动服务于矿产勘查,要深入野外一线并将继承与开创很好地结合。     

Seismic reliability of traditional and innovative concentrically braced frames

Structural engineering problems are always affected by many sources of uncertainty, such as aleatory of material properties, applied loads and earthquake intensity, therefore, seismic assessment of structures should be based on probabilistic methods. Since PBSD (Performance‐based Seismic Design) philosophy was formulated, many researches have been conducted in this field in order to develop simple and accurate procedures for evaluating structural reliability. An important contribution has been provided by Jalayer and Cornell, who have developed a closed‐form expression to evaluate the mean annual frequency of exceeding a defined limit state. In this paper, by assuming the record‐to‐record variability as the only source of uncertainty, the seismic reliability of concentrically braced frames designed according to traditional and innovative methodologies is investigated, and a comparison between their performances is presented. In particular, two design methodologies have been applied: Eurocode 8 provisions and a new design methodology based on a rigorous application of ‘capacity design’ criteria. The innovative reduced section solution strategy, based on the reduction of cross sections at bracing member ends, has also been analysed. Copyright © 2011 John Wiley & Sons, Ltd.     

Editorial

As we will soon celebrate the 90th anniversary of the founding of the Chinese Meteorological Society （CMS）,Acta Meteorologica Sinica （AMS）,which was originally named as Bulletin of the Chinese Meteorological Society,has gone through 89 years of development and excitement since her first issue in July 1925.According to archived documents （CMS Editorial Committee,1925）,AMS was founded to report the research findings of Chinese meteorologists,record their recommendations for improving meteorological services,and share their common meteorological interests in order to promote the growth of AMS such that more members could be inspired to conduct atmospheric research and meteorological knowledge would be better disseminated to and benefit the general public.By upholding and carrying forward this purpose,AMS has published many highly valuable scientific papers.Some could be treated as classical articles,which have produced important influences on both domestic and international meteorological communities and the related fields.
