    创业创新大潮如期而至,创业团队作为创业型企业的经营主体,可谓是企业生存和创新的灵魂。现有文献和实践都表明,团队的特征和状态都与企业动态能力、创新绩效存在密不可分的联系。随着嵌入性概念在管理学领域的延伸,研究者大多从组织和个体角度聚焦嵌入性与企业动态能力和创新绩效的关系,却鲜有关注团队层面嵌入性对企业动态能力和创新绩效的影响。 本文以国内外文献检索为前提,回顾了创业和嵌入性领域的相关理论和实证成果,结合当前的现实需求,尝试界定创业团队层面的嵌入性概念,并采用访谈分析法析出创业团队嵌入性的概念,并开发和验证创业团队嵌入性的测量量表。同时基于动态能力理论,借鉴团队创新模型,提出创业团队嵌入性、动态...The huge trend of entrepreneurship and innovation comes as the times, entrepreneurial team as operators of entrepreneurial enterprises, is the soul of survival and innovation. Existing literature and facts show that the state and characteristics of entrepreneurial team have close connections with dynamic capabilities and innovation performance.

    近些年来,“建设社会主义新农村”、“建设中国农村社会保障制度”、“和谐 社会需要国民共享改革成果”、“人口老龄化带来世纪养老危机”正引起越来越多 的关注。在这四个宏观经济运行背景下,如何妥善解决中国约9亿农民的养老不 仅是学术问题,也是基于基本的公平正义、国家稳定以及经济可持续发展的现实 问题。 虽然我国的社会保障体系建设目前已经取得了重大进展,但是由于把重点放 在了城镇,我国农村社会保障问题的研究还较为薄弱,而农村养老又是其中的重 中之重。自农村实行家庭联产承包责任制以来,集体经济的削弱,使得在此基础 上建立的农村社会养老保险制度对广大农民的社会保障功能日趋弱化,存在诸多 ...Nowadays,more and more attention is being paid to four aspects--building a new socialist countryside,the construction of China's rural social security system,sharing the resuits of the reform,and the aging of the population has brought the century crisis of old-age.Under those four macro—economic backgrounds,how to properly resolve the endowment of about 9 million farmers in China is not only ...学位:经济学硕士院系专业:经济学院财政系_财政学(含税收学)学号:1552007115005

    城市可持续发展是人类全面实施可持续发展战略的一个重要方面 ,它有其特定的内涵。城市规划是实施城市可持续发展战略的有效工具 ,在城市规划中引入可持续发展理论是引导城市可持续发展的重要一环。以可持续发展为原则的城市规划应突出其未来导向性、环境导向性、社会导向性的特点 ,文章就其含义及实现途径进行了分析和探讨。Urban sustainable development is an important part of sustainable development strategy. The urban planning is an effective means to put into effect sustainable development strategy in city. It is also an important link to guide urban sustainable development when sustainable development theory was used in the urban planning. According to sustainable development principle, the urban planning should have characteristics of tendency towards future, towards eco-environmental protection and towards community.加拿大国际发展署 (CIDA)支持;; 中、加、越三方合作开展的公众基础的保护与管理项目资

    战略环境评价(SEA)就是对政策、计划/规划及其各种替代方案的环境影响进行规范的、系统的、综合的分析和评价过程.以海岸带可持续发展为目标的SEA应遵循与战略决策过程紧密结合、综合、多元评价标准及公众参与4个基本原则进行厦门岛东部海岸发展规划的战略环境评价案例研究.:The strategic environmental assessment (SEA) is discussed and proved as an effective tool to realize the sustainable development in coastal zone in aspects of complex natural ecosystem, multiple human activities and disadvantages of project EIA in coastal zone. Four basic principles should be followed for developing the SEA in coastal zone, including close integration with decision-making, comprehension, multiple assessment criterion and public participation. These should be applied for assessing the planning of east coastal zone of Xiamen.加拿大国际发展署资助项目!(#UPCD Tier1 Program O1843-S53305

    为揭示南海北部表层海水中参与卡尔文循环的固碳基因多样性及其与环境因子的关系,本研究以卡尔文循环中的关键酶核酮糖-1,5-二磷酸羧化酶/加氧酶(Rubis CO)的Ⅰ、Ⅱ型基因(cbbL、cbbM)作为分子标记,采用Illumina Miseq高通量测序技术对海水中的固碳基因多样性进行分析,并结合多元统计分析的方法,探讨了固碳基因多样性与环境因子的关系.结果显示,在南海北部表层海水中,含cbbL基因固碳基因主要归属于变形菌门(Proteobacteria)、蓝藻门(Cyanobacteria)和厚壁菌门(Firmicutes),其中,优势亚群分别是γ-变形菌亚门(45.3%)、蓝细菌(30.9%)和β-变形杆菌亚门(23.8%);而含cbbM基因的固碳菌群未检测到;近岸的A9站位与其他站位物种组成有一定的差异,异着色菌属(Allochromatium)、硫杆菌属(Thiobacillus)和硫单胞菌属(Thiohalomonas)为其特有菌属.相关性和冗余分析(RDA)结果显示,含cbbL基因的固碳基因丰度与水温、盐度呈显著负相关(p<0.01),与硝酸盐、亚硝酸盐、硅酸盐呈显著正相关(p<0.01).To elucidate the diversity of CO_2 fixation and its relationship with environmental factors in surface water of northern South China Sea,the coding gene form I( cbbL) and form II( cbbM)( that encodes Ribulose-1,5-biphosphate carboxylase/oxygenase( Rubis CO) were chosen as biomarkers in Calvin-Benson-Bassham cycle( a common carbon fixation pathway for chemolithoautotrophic microorganisms) to analyze the carbon sequestration gene diversity. The Illumina Miseq sequencing method and multivariate statistical analysis were employed. The cbbM gene was not detected in any of samples,while the cbbL gene was found in all samples. The cbbL-containing genetic communities were dominated by Proteobacteria,Cyanobacteria and Firmicutes,in which γ-Proteobacteria( 45. 3%),Cyanobacteria( 30. 9%),β-Proteobacteria( 23. 8%) were predominant subpopulation. There were differences between the nearshore station of A9 with other stations,in which Allochromatiu,Thiobacillus and Thiohalomonas were unique species in A9 station.Relativity and redundancy analysis suggest that water temperature, salinity, nitrate, nitrite, silicate were highly statistically significant factors.Temperature and salinity were positively( p < 0. 01),while the other three factors negatively influenced CO_2 fixation gene of cbbL gene abundance( p <0. 01).全球变化与海气交互作用专项(No.GASI-03-01-02-05);; 海洋公益性行业科研专项(No.201305030,201405007)~
