对省级行政区域城市群构建的思考——以构建大南昌城市群为例

城市群已成为国家或地区参与全球竞争与国际分工的基本地域单元。基于省级行政区域构建城市群在我国很有必要。本文以构建大南昌城市群为例,重点探讨省级行政区域城市群构建的理论基础、城市群形成与成长的条件。研究表明：江西应构建以南昌为中心,包括九江、新余、抚州、鹰潭等城市在内的大南昌城市群,使其成为全国的高技术产业及现代制造业基地、农产品生产与加工基地和综合交通运输枢纽,成为一个空间结构合理、社会经济与资源环境协调发展、具有竞争力的经济密集区。为此,江西应遵循大城市群成长规律,从规划、机构、区域分工与合作、城镇空间结构、一体化、区域创新和产业集群等方面统筹谋划,分步实施。     

产业集聚理论对中西部地区发展民营经济的应用分析

产业集聚是区域竞争优势的源泉 ,已成为发达国家、发达地区产业成长的一个显著特征。产业集聚的本质是外部经济 ,这一外部经济的主要来源有劳动市场的共享、专业性附属行业的创造和技术外溢。产业集聚可以减少环境的不确定性 ,有利于知识和技术的传播与扩散 ,形成创业空间集聚的正反馈效应 ,已经成为区域参与全球竞争的重要力量。我国中西部地区民营经济发展基础差、总量小、比重低 ,空间上的分散配置存在着私人供给的公共产品溢出效应损失 ,服务产品需求的市场外效应损失 ,信息的、知识和技术溢出效应损失。改变这一状况的一个有效途径就是在重点地区实现产业集聚 ,为民营经济的发展创造条件 ,促进工业化 ,推进城镇化 ,提升区域经济的竞争力水平     

Heteroplasmies detected in an amplified mitochondrial DNA control region from a small amount of template

When mitochondrial DNA (mtDNA) heteroplasmies are detected, they often confound forensic identification, especially if they are the result of poor biological sampling. In this study, we determined the ratio of heteroplasmy in samples that were amplified from a very small amount of template mtDNA or a few cells using a highly sensitive nested polymerase chain reaction (PCR) procedure and a direct sequencing analysis. As a result, more than half of the detected sequences (i.e., 17/20, 15/20, and 14/20) showed homoplasmy derived from a variation in the heteroplasmy proportion when only 10 copies of template mtDNA samples were amplified and analyzed. Additionally, with products amplified from one or several white blood cells (WBCs), several previously undetected heteroplasmies were detected. These results indicate the risks associated with using highly sensitive mtDNA techniques in forensic investigations because of the variable proportions of heteroplasmy or nucleotide substitutions that can possibly be detected from a very small biological sample.     

Forensic utility of the mitochondrial hypervariable region 1 of domestic dogs, in conjunction with breed and geographic information

The 608-bp hypervariable region 1 (HV1) sequences from 36 local dogs were analyzed to characterize the population genetic structure of canid mitochondrial DNA (mtDNA). Sixteen haplotypes were identified. A 417-bp segment of this sequence was compared with GenBank sequences from a geographically representative sample of 201 dogs, two coyotes, and two wolves. Sixty-six haplotypes were identified including 62 found only in domestic dogs. Fourteen of these correspond to the 16 local haplotypes and were among the most frequent haplotypes. The local sample was judged to be representative of the much broader geographic sample. No correlation was observed between local haplotypes and the owner's characterization of dog breed. A 60-bp variation "hotspot" within the canid HV1 was identified as a potentially valuable molecular tool, particularly for assaying limited or degraded DNA samples.     

不同地域痹证中医药治疗特色

痹证是因风、寒、湿、热等外邪侵袭人体,闭阻经络而导致气血运行不畅的病证。痹证的发生与体质的盛衰以及气候条件、生活环境密切相关。西北方之人患痹证,宜用疏通重剂、温热之药;东南方之人患痹证,宜用疏通轻剂、清凉之品;中部之人患痹证,当因地制宜。以中医理论为指导,结合痹证的现代研究,基于中医地域医学特色,探讨不同地域痹证的辨证及治疗特色具有重要意义。

能否造就一支宏大的德才兼备的少数民族干部队伍,事关党的民族政策能否真正落到实处,事关民族地区的经济社会发展,事关民族地区的振兴乃至整个中华民族的振兴.     

从产业结构分析我国西部开发的融资行为

能否获得足够的资金支持关系着西部大开发的成败,而投资的效益则决定着资金的流向,从而影响着产业的布局。本文从产业结构角度研究西部开发的资金运用情况,为西部大开发的融资提出政策性建议。     

以先进文化促进陕西经济的发展

先进文化对经济的发展具有很大的促进作用。而对于经济相对落后的陕西,改造落后文化,建设先进文化以求促进经济的发展尤为紧迫。在当代中国,先进文化即有中国特色的社会主义文化,其内涵丰富。陕西建设先进文化的当务之急是加快建立与社会主义市场经济相适应的新经济文化。

“While a Storm is Raging on the Open Sea”: Regional Development in a Knowledge-based Economy

The Triple Helix of university–industry–government (UIG) relations is elaborated into a systemic model that accounts for interactions among three dimensions. By distinguishing between the respective micro-operations, this model enables us to recombine the “Mode 2” thesis of a new production of scientific knowledge and the study of systems of innovation with the neo-classical perspective on the dynamics of the market. The mutual information in three dimensions provides us with an indicator for the self-organization of the resulting network systems. The probabilistic entropy in this mutual information can be negative in knowledge-based configurations. The knowledge base of an economy can be considered as a second-order interaction effect among interactions at interfaces between institutions and functions in different spheres. Proximity enhances the chances for couplings and, therefore, the formation of technological trajectories. The next-order regime of the knowledge base, however, can be expected to remain pending as selection pressure.
