适合鸭瘟病毒弱毒增殖的MHC单倍型鸭胚肝间充质干细胞的建立

为了建立适于鸭瘟病毒(DPV)弱毒增殖的细胞系,利用4个主要组织相容性复合体(MHC)单倍型鸭品系,体外分离鸭胚肝细胞,在干细胞因子、白细胞抑制因子和成纤维细胞生长因子诱导下,获得鸭胚肝间充质干细胞(DuLMSC)。接种DPV疫苗株C-KCE后,结果显示:F1~F10代均能稳定出现CPE;将F10病毒接种细胞24 h后,通过扫描电镜在胞质、胞核及细胞间隙均能够观察到典型的疱疹病毒粒子;F1至F10代均能扩增出DPV UL2基因片段,序列测定结果表明F1、F5、F10代的扩增产物与NCBI中公布的DPV株(EU082088)的核苷酸同源性为100%;组织培养半数感染量和一步生长曲线结果表明,源自B4系单倍型鸭的DuLMSC细胞系增殖DPV的病毒含量明显高于B1、B2和B3系。本研究为稳定培养鸭瘟病毒提供了优良稳定的实验材料。     

公安学、警察学及其相互关系

公安即社会安全 (Socialsafety) ,是指人类社会的安全、稳定和秩序。公安学 (Socialsafetytheory)是关于人类社会安全问题的学问 ,研究什么是人类社会的安全 ,为什么人类社会会出现安全问题 ,怎样才能实现人类社会的安全 ,其主要范畴有安全、稳定、秩序和与之对应的战争、动乱、恐怖、灾害等。警察是指对人类社会的安全、稳定和秩序的守护 ,即对于侵害社会安全的事物的预防、察知、警报和即时抗击。警察学 (policetheory)是关于如何预防、察知、警报和即时抗击侵害社会安全的事物的学问 ,研究什么是警察 ,为什么要警察 ,怎样警察 ,其主要范畴有警察、安全、危害、犯罪等。公安学与警察学是两个区别很大的学科 ,但两者间的联系也不能忽视。     

中国引渡立法的若干理论问题

引渡法不是基本法。引渡法具有部门法的性质 ,是由一系列针对引渡事项的程序规则组成的法律 ,属于特殊程序法 ,又是解决国际刑事司法协助问题的专门法。引渡的性质是国家之间进行合作的一种形式 ,是国家实现司法主权的体现 ,仍然属于刑事法律范畴的事务。在我国引渡法中运用政治犯罪不引渡原则。引渡法中的裁定权主要有两类 :即行政裁定权和司法裁定权。我国采用行政审查和司法审查模式是可行的方案。在引渡法中引入人权保障的观念是现代引渡法发展的一个重要方面     

Human Security and Constructivism

This article explores the concept of "human security" as an academic and fledgling policy movement that seeks to place the individual—or people collectively—as the referent of security. It does this against a background of evolving transnational norms relating to security and governance, and the development of scientific understanding that challenges orthodox conceptions of security. It suggests that human security is not a coherent or objective school of thought. Rather, there are different, and sometimes competing, conceptions of human security that may reflect different sociological/cultural and geostrategic orientations. The article argues that the emergence of the concept of human security—as a broad, multifaceted, and evolving conception of security—rreflects the impact of values and norms on international relations. It also embraces a range of alliances, actors, and agendas that have taken us beyond the traditional scope of international politics and diplomacy. As a demonstration of change in international relations, of evolving identities and interests, this is best explained with reference to "social constructivist" thought, in contradistinction with the structural realist mainstream of international relations. In a constructivist vein, the article suggests that empirical research is already building a case in support of human security thinking that is, slowly, being acknowledged by decision-makers, against the logic of realist determinism.     

The Attlee government and welfare state reforms in post-war Italian Socialism (1945–51): Between universalism and class policies

The purpose of this article is to analyse how the Italian socialist movement viewed the social reforms of the Attlee Labour government introduced just after the Second World War. The intention is to study the extent and limits of the labour influence on Italian socialism. The Labour Party made the re-founding of a new interclass social pact, a universal matter intending to meet the needs of both the working and middle classes. The Italian socialist movement monitored the Labour government’s changes with interest, assessing them from two different perspectives. The reformist wing had a better grasp of the political–ideological implications of Labour’s approach to the welfare state. Vice versa, the majority of the Italian socialists pursued a class socialism and a strong alliance with the Communist Party, rejecting the Labour social policy model. After the split of 1947, however, the two views of Italian socialism failed to develop and implement a political programme for a welfare state based on the British universalistic tendency model. The political weaknesses of Italian socialist organizations in the field of social policy contributed to the characterization of the Italian welfare state in the post-war period and fundamentally delayed its universalistic implementation, at least until the 1960s.     

Jewish joke telling in Muttersprache Mameloschn: performing queer intervention on the German stage

This essay explores the central role of Jewish joke telling in Sasha Marianna Salzmann’s play Muttersprache Mameloschn (first performed in 2012). Subversively revealing the problematic of essentializing cultural, national, and even sexual identity, Jewish joke telling figures as a performance of social and political resistance and disidentification in this play. Engaging with Jack Halberstam’s queer epistemology of failure and José Esteban Muñoz’s theory of queer disidentification, I propose that the act of Jewish joke telling by a young lesbian plays out as a new queer project of intervention in this play that confronts both antisemitism and culturally positioned sexual hegemony.     

Gendered discourses of facilitation in a probation learning environment: challenging the heteronormative ideal

This article focuses on the cognitive behavioural rehabilitation programmes run by the probation service in the UK. Drawing on Judith Butler's assertion that both sex and gender are discursively produced and Becky Francis' notion of gender monoglossia and heteroglossia, the article seeks to analyse and problematise the gendered discourses of facilitation that were mobilised by policy-makers and practitioners in this setting. The dominant institutional model of heteronormative facilitation promoted the ideal of each programme being delivered by one female and one male facilitator in order to provide a gender ‘balance’. But underpinning this ideal lay the binarised and essentialist notion that ‘masculinity’ arose naturally from the male body and ‘femininity’ from the female body. Female facilitators were positioned as bringing a calming and non-threatening atmosphere to the group and as naturally possessing skills of ‘empathy’ and ‘warmth’. Male facilitators were highly valued by managers, but were also under pressure to perform masculinity in very specific ways that were linked to notions of intellectual, rational, ‘middle-class’ masculinity. Through an analysis of interviews with probation practitioners and session observations, the article highlights that despite these dominant institutional constructions, a variety of complex and contradictory performances of ‘masculinity’ and ‘femininity’ were mobilised in this environment.     

The Young-Girl in Theory

This essay situates Tiqqun's Preliminary Materials for a Theory of the Young-Girl within a long history of leftist art and theory that uses the figure of the girl to respond to, reflect on, and even to attempt to subvert the various subjective crises of late capitalism. At the same time, and reading Tiqqun against the grain, it asks whether the Young-Girl might be of any use for thinking through the new questions about subjectivity and representation that neoliberalism has presented for feminism.     

警察临战:和谐目标下的危机管理

加强公共危机管理是构建和谐社会的重要内容。警察临战是公共危机管理的重要组成部分,它为公共危机管理决策提供服务,为公共危机管理提供资源保障,它是公共危机管理的重要手段。危机管理是警察临战学的理论基础。     

社区警察人际交往的PAC理论及其训练模式

据警务专家统计分析,一名社区警察在工作中大部分的时间和精力是在同社区公众接触,为公众提供各类服务,而只有较少的时间才是面对真正的犯罪嫌疑人。如果社区警察不注重交往技能和心理调控训练,势必会影响警民关系,给社区警务工作带来不便。PAC理论为我们提供交往技能训练提供了理论依据,可以为我们对警察人际交往训练提供理论指导。
