摘要： Y-DNA基因是以单倍型的形式独立地由父亲遗传给儿子的方式进行传递,呈现单倍父系遗传特征。Y-STR基因多态性作为常染色体STR的一种补充手段,该分析技术正越来越受到重视,其对发案现场家系进行嫌疑排查、在人类起源的研究,父系亲权鉴定,男女混合成份中男性成份的检测以及多个男性混合成份的同一认定等方面有着十分重要的应用价值。

关键词： supercritical fluid chromatography (SFC)   stationary phases classification   unified chromatography   reversed-phase   normal-phase   linear salvation energy relationship (LSER)   salvation parameter model  

摘要： The use of supercritical fluids as chromatographic mobile phases allows to obtain rapid separations with high efficiency on packed columns, which could favour the replacement of numerous HPLC methods by supercritical fluid chromatography (SFC) ones. Moreover, despite some unexpected chromatographic behaviours, general retention rules are now well understood, and mainly depend on the nature of the stationary phase. The use of polar stationary phases improves the retention of polar compounds, when C18-bonded silica favours the retention of hydrocarbonaceous compounds. In this sense, reversed-phase and normal-phase chromatography can be achieved in SFC, as in HPLC. However, these two domains are clearly separated in HPLC due to the opposite polarity of the mobile phases used for each method. In SFC, the same mobile phase can be used with both polar and nonpolar stationary phases. Consequently, the need for a novel classification of stationary phases in SFC appears, allowing a unification of the classical reversed-and normal-phase domains. In this objective, the paper presents the development of a five-dimensional classification based on retention data for 94-111 solutes, using 28 commercially available columns representative of three major types of stationary phases. This classification diagram is based on a linear solvation energy relationship, on the use of solvation vectors and the calculation of similarity factors between the different chromatographic systems. This classification will be of great help in the choice of the well-suited stationary phase, either in regards of a particular separation or to improve the coupling of columns with complementary properties.

摘要： 围绕中心、服务大局，是思想政治工作的关键所在，也是唱响主旋律、打好主动仗的重要前提。如何坚持在大局中定位、尽责、有为，充分发挥思想政治工作的保证作用，促进检验检疫事业又好又快发展？我认为就当前的情况看，思想政治工作要在以下五个方面更加有所作为。

关键词： 资本账户开放   资本流动   经济增长   作用路径  

摘要： 资本账户开放曾被誉为是发展中国家经济发展的必经之路。但至今为止，这种开放的实际影响仍然是国际金融领域颇具争议的焦点问题。20世纪90年代，许多发展中国家相继放松资本管制，其资本账户的开放推动了经济的快速发展。但另一方面，资本账户开放也给发展中国家带来巨大的挑战和潜在风险。发展中国家在接受巨额资本流入的同时，也遭受了严重的资本流动逆转引致的金融危机的袭击。这就促使众多经济学者对资本账户开放这一重大金融问题，进行重新审视和研究。\n 如今，我国也迈出了资本账户开放的步伐。从最初吸引外商直接投资、适度对外借债、建立合格境外机构投资者制度、有序对外开放境内证券市场，到实施有条件的企业“走出去”战略、放宽境外投资汇兑限制、实施合格境内机构投资者制度，资本账户开放程度日益加深。然而任何开放措施都应本着驱利除弊，促进经济增长的目标而展开。因此，从宏观角度分析我国资本账户开放与经济增长的关系及影响显得尤为重要。\n 本文选取资本账户开放与经济增长关系这一视角展开论述，并分析我国资本账户开放对经济增长的影响。文章首先对资本账户开放概念做一个界定，然后归纳了国际上各种测度资本账户开放的方法，并结合中国实际情况和文章立意，量化中国资本账户开放度的指标，为后面章节的计量分析提供可能：其次，本文总结了国内外资本账户开放与经济增长的理论研究与实证研究。特别在实证研究这一部分，发现不同学者关于资本账户开放与经济增长关系问题有不同的结论：资本账户开放促进经济增长、资本账户开放与经济增长无关、资本账户开放对经济增长的影响不确定。再次，鉴于结论的不一致，本文在国内外研究成果基础上，立足中国国情，采用计量分析方法，对我国资本账户开放度与经济增长关系进行实证检验，并得出资本账户开放长期内促进我国经济增长的结论。最后，文章回顾了我国资本账户开放的历史进程，并根据前一部分的实证结果，结合中国实际发展情况，从实业投资、货币供给、证券市场、银行体系四个金融层面，探索资本账户开放促进我国经济增长的作用路径。

关键词： MANAGEMENT -- Research   BUSINESS enterprises -- Finance   TRADING companies   CONTRACTING out   BUSINESS models   INDUSTRIAL relations  

摘要： Exporting relationships between manufacturers and foreign importers pose unique coordination problems because, on the one hand, transactions are recurrent and both firms make non-trivial relationship-specific investments, but at the same time, the exchange partners maintain separate legal entities with individual profit claims. This study examines the role of contracts as a governance mechanism in these relationships that are neither market-based discrete transactions, nor can be governed through ownership-based hierarchies. Drawing upon recent research on contract law and interorganizational relationships, we develop and empirically test a model that incorporates both the antecedents and performance implications of the nature of contract governing exporter-importer relationships.

关键词： support vector machine   decision theory   posterior probabilities   matrix-variate normal distribution  

摘要： In this paper, an entirely new procedure for the classification of high-dimensional vectors on the basis of a few training samples is described. The proposed method is based on the Bayesian paradigm and provides posterior probabilities that a new vector belongs to each of the classes, therefore it adapts naturally to any number of classes. The classification technique is based on a small vector which can be viewed as a regression of the new observation onto the space spanned by the training samples, which is similar to Support Vector Machine classification paradigm. This is achieved by employing matrix-variate distributions in classification, which is an entirely new idea.

关键词： asylum   critical discourse analysis   corpus   discourse historical approach   discrimination   method   migrants  

摘要： This article discusses the extent to which methods normally associated with corpus linguistics can be effectively used by critical discourse analysts. Our research is based on the analysis of a 140-million-word corpus of British news articles about refugees, asylum seekers, immigrants and migrants (collectively RASIM). We discuss how processes such as collocation and concordance analysis were able to identify common categories of representation of RASIM as well as directing analysts to representative texts in order to carry out qualitative analysis. The article suggests a framework for adopting corpus approaches in critical discourse analysis.
