中国北方7个群体血痕GLOI遗传多态性现象的研究

应用琼脂糖水解淀粉凝胶平板电泳法，对中国内蒙古呼盟鄂伦春、鄂温克、达斡尔、布里亚特、（东北）蒙古人及包头市（西北部）蒙古族、汉族人血GLOI遗传多态性进行了调查，抽样检测7个群体GLOI表型分布频率，计算出基因频率和识别能力。并将本组7个群体表型频率、基因频率与国内外不同民族、不同地区的表型频率和基因频率进行了比较，阐述了上述7个群体GLOI遗传多态性特征。根据表型频率计算出识别能力（DP值），并评价了GLOI在亲子鉴定和个体识别中的应用价值。     

鸡IL-18基因重组真核表达载体的构建及其表达产物的生物学活性

从pMDChIL18克隆质粒扩增获得了ChIL18全基因片段,并将其重组到真核表达载体pcDNA3.1( )。经酶切、质粒PCR鉴定和基因测序,鸡IL18全基因被正确重组到pcDNA3.1( )真核表达质粒上;将重组真核表达质粒pcDNA3.1( )ChIL18转染COS7细胞,转染细胞中含ChIL18基因的mRNA。SDSPAGE分析表明,表达产物是与ChIL18相符的约23ku的蛋白条带。鸡淋巴细胞转化试验表明,表达产物对鸡淋巴细胞具有明显诱导转化作用。

目的 了解D3S1754、D18S535基因座多态性在中国北方人群中的分布特点及其应用价值。方法 使用PCR、聚丙烯酰胺垂直板电泳及银染的方法。结果D3S1754基因座检出9个等位基因（n=184）,D185535基因座检出8个等位基因（n=201）,两个位点的等位基因频率在群体中的分布符合Hardy-Weinberg平衡（P>0.05）,它们的杂合率（He）分别为0.706和0.807,个人识别机率（DP）分别是0.859和0.934,非父排除率（EPP）分别为0.464和0.629。结论 D3S1754、D18S535两个遗传标记的个人识别率高、非父排除能力较强且能稳定遗传,具有较高的应用价值。     

Phenolphthalein False‐Positive Reactions from Legume Root Nodules

Presumptive tests for blood play a critical role in the examination of physical evidence and in the determination of subsequent analysis. The catalytic power of hemoglobin allows colorimetric reactions employing phenolphthalein (Kastle‐Meyer test) to indicate “whether” blood is present. Consequently, DNA profiles extracted from phenolphthalein‐positive stains are presumed to be from blood on the evidentiary item and can lead to the identification of “whose” blood is present. Crushed nodules from a variety of legumes yielded phenolphthalein false‐positive reactions that were indistinguishable from true bloodstains both in color quality and in developmental time frame. Clothing and other materials stained by nodules also yielded phenolphthalein false‐positive reactivity for several years after nodule exposure. Nodules from leguminous plants contain a protein (leghemoglobin) which is structurally and functionally similar to hemoglobin. Testing of purified leghemoglobin confirmed this protein as a source of phenolphthalein reactivity. A scenario is presented showing how the presence of leghemoglobin from nodule staining can mislead investigators.     

川藏人民支援进军西藏

194 9年底 ,西南战役胜利结束 ,进军西藏已成为既定目标。西藏当局中亲帝国主义分子拒绝中共中央提出和平解放西藏的方案 ,以军事手段相对抗。根据国际国内形势 ,毛泽东作出了进军西藏的决策。根据中央的部署 ,西南局决定 18军进藏。 18军在甘孜、巴塘认真贯彻党的民族宗教政策 ,赢得了藏区人民的广泛爱戴和拥护 ,为解放西藏做出了重要贡献。     

Conversations with Rosângela Silvestre and Steve Coleman

This article incorporates material from separate interviews with Rosângela Silvestre and Steve Coleman, two artists who have maintained common research interests and frequent collaboration over the last decade. Silvestre, a Brazilian dancer and choreographer who has incorporated “traditional” movement vocabularies into her experimental work, and Coleman, an innovative American musician whose work also defies categorization, both reflect on the technical mastery underlying improvisation, the blurry boundaries between movement and music-making, and the significance of gender in collaboration.     

马来亚印度人国大党的成立及早期政治活动(1946~1957)

二战前,马来亚印度人指向祖籍国印度的民族主义和爱国主义明显加强,进而暂时消除、弥合了印度人群体中一些分化因素,这是马来亚印度人国大党成立的重要社会背景。在尼赫鲁的积极推动下,1946年8月,马来亚印度人国大党正式成立。虽然马来亚印度人国大党深受尼赫鲁和印度国大党的影响,该党成立之初也支持当时的印度政府和印度国大党的反殖反英运动,但它并不隶属于印度国大党。自成立后至1957年,马来亚印度人国大党先是主要致力于开展印度民族主义的活动,不久又深度卷入马来亚制订民主宪法的斗争中,积极争取对印度人有利的公民权问题。在马来亚积极争取独立的浓厚政治氛围中,经过一番犹豫之后,1955年3月,经正式商谈之后,马来亚印度人国大党选择全面加入巫统马华联盟。同年7月,巫统、马华公会和马来亚印度人国大党结成的三大民族政党联盟在竞选中获胜。马来亚联合邦随后正式成立,马来亚印度人国大党作为执政联盟成员之一,长期参与执政。印度人群体的相对弱小及其社会内部的严重分化,部分程度地削弱了马来亚印度人国大党在马国政治中的地位和作用。它的政治活动对马来亚的政治民主化和多元化起到了一定的推动作用。     

To P or not to P? The Usefulness of P‐values in Quantitative Political Science Research

This contribution gives a short overview over the mechanics of significance testing in inferential statistics, in particular linear models, and tries to put the discussion about the usefulness of p‐values into a broader perspective of scientific practise. This discussion needs to be embedded into the larger debate about the credibility crises faced by empirical social science research. In particular, it seems of utmost importance to discuss what the profession as a whole, journals, publishers, as well as editors can do to encourage better research practise that generates reliable and useful empirical findings.     

After Sarajevo: Explaining the Blank Check

This paper uses an incomplete information game model to describe and explain the so-called blank check issued to Austria by Germany in early July 1914. It asks why Germany would cede control of an important aspect of its foreign policy to another lesser power. The derived explanation is consistent not only with the actual beliefs of German and Austrian leaders but also with an equilibrium prediction of the game model. The issue of whether unconditional German support of Austria constituted either a necessary or a sufficient condition for the outbreak of major power war the next month is also addressed.     

西部大开发中的生态环境保护问题研究

中国西部是少数民族的主要聚居区,但是,西部地区有严重的生态问题,而且投入不足,立法也不完善。这些都对西部的经济发展提出了挑战,所以,要实现西部的可持续发展,必须把生态环境的保护和建设放在重要地位,按照自然规律办事,在尊重环境的前提下实行可持续发展。
