对我国公安干训教学几个问题的思考

我国公安高等院校肩负着学历教育和民警培训两大任务。国际国内形势迫切要求公安高等院校在抓好学历教育的同时,必须高度重视民警培训工作并将其放在更加突出的地位。因此,在准确把握公安干训教学原则的基础上,必须坚持以教学理念的创新引领教学的创新方向,以教学内容的创新推进教学的创新深度,以教学模式的创新深化教学的创新力度,以教学方法与手段的创新增强教学的创新活力。同时还要科学预见公安干训教学的网络化、国际化和个性化趋势,做到未雨绸缪、从容应对。     

Sustainable reintegration to returning refugees in post-Taliban Afghanistan: land-related challenges

The lives of millions of people around the world continue to be thwarted with violence, obliging them to flee from their own country or community mainly for reasons of persecution and armed conflict. Resolving this problem is a complex and pressing challenge. This is because of their needs not only while in exile, but also during their return home as the situation improves, ensuring their rights to protection and sustaining their reintegration requirements. This article focuses on the return of refugees in post-war situations, and the challenges and complexities of ensuring a durable return and sustainable reintegration in the country of return. It focuses on ‘land’, and the concerns and complexities surrounding it as one of the key obstacles to the sustainability of return and reintegration. Within a general discussion, the issue of land is explored by looking at it in the context of returnee reintegration against the backdrop of various aspects such as security, politics, disputes, restitution and livelihoods. The case in discussion is Afghanistan, referring to the voluminous return of refugees and the challenges in seeking solutions to their reintegration problems since the political changes in late 2001 underlined by the US-led military intervention, the ouster of the Taliban regime and the Bonn Agreement.

商品疫苗对FMDV O/YNGM/97株的免疫效果评价

利用血清学方法对我国流行毒株O/YNGM/97进行鉴定.并对其生物学特性和免疫学特性进行了研究.结果显示,该流行毒株为O型12蹄疫病毒(FMDV),其对乳鼠和BHK21细胞的适应性比较好,致病性较强,LD50.和TCID50分别为10-6.33/0.2 mL和10-4.75/0.05 mL.VP1基因序列的比较结果显示,O/YNGM/97株与国外FMDV参考毒株O/TAI/1/92的同源性为91.4%,与国内疫苗毒株OZ/93、OA/58和OY/80的同源性分别为79.2%、83.6%和78.99/6.用商品疫苗OZ株、OY株口蹄疫O型灭活疫苗和牛羊.口蹄疫O-Asial型双价灭活疫苗免疫的小鼠均可产生较高的免疫抗体,并对流行毒株O/YNGM/97的攻击具有较好的保护性.说明,使用现有商品疫苗完全可以预防该毒株在我国的流行.     

对当代资本主义阶级关系新变化的有益探索——赖特的《阶级》一书评介

阶级分析理论是马克思历史唯物主义的重要组成部分。二战以后,随着科学技术上的革新带来的社会经济的发展,使资本主义社会经济结构和就业结构发生变化,从而造成当代资本主义社会的阶级关系出现新的变化,呈现出新的特征。正是由于这些变化,一些人开始质疑阶级分     

蛋鸡输卵管中与精子储存相关四种酶分布的组织化学染色观察

应用组织化学方法在组织和细胞水平上对碱性磷酸酶、酸性磷酸酶、过氧化氢酶以及三磷酸腺苷酶在蛋鸡输卵管内的分布特点及分布意义进行了研究分析。结果显示,4种酶在蛋鸡输卵管各段的分布部位以及反应强弱存在差异。碱性磷酸酶在子宫部分布最多,在有精子储存的黏膜固有层腺体和血管周围也有明显分布;酸性磷酸酶在阴道子宫交界部分布最多,酸性磷酸酶阳性反应呈颗粒状,主要分布于黏膜上皮和固有层腺体;过氧化氢酶在输卵管各段血管周围以及子宫阴道交界处精子腺和蛋白分泌部反应明显;三磷酸腺苷酶在各段尤其是子宫阴道交界处精子腺部位黏膜上皮纤毛和腺体分布较多,血管也有一定分布。表明这些酶在精子储存时对精子的活性和储存环境的维持、物质运输及分泌等活动具有一定的生物学作用。     

非结构蛋白2高变区在PRRSV复制中的作用

为了研究nsp2的非必需区在动脉炎病毒复制中的作用,采用定点突变PCR(site direct PCR)法对PRRSV全长感染性克隆pAPRRS的nsp2进行了系列缺失。结果显示,通过病毒拯救发现,nsp2部分区段可以忍受一定程度的缺失,但大幅度的缺失影响了病毒的复制、RNA合成翻译甚至病毒颗粒的成熟过程。结果表明,nsp2中多个氨基酸的变化可能影响PRRSV中多聚蛋白的水解、加工、成熟或RTC的组装。     

The Emerging Threat? South Africa's Extreme Right

In the run-up to South Africa's first non-racial election in 1994, extremist right-wing organizations, and their sympathizers in the state security forces, posed a real danger to the country's future democratic order. After 1994, violent, right-wing extremist activities virtually dissipated. However, during a single night in late 2002, eight bomb blasts rocked Soweto, South Africa's largest black township. An unknown organization, Boeremag (Boer force/power), claimed responsibility for the bombings. Some two dozen alleged Boeremag members, including serving military officers, were subsequently arrested and charged with terrorism-related offenses. The Boeremag makes an interesting case study of how the extreme white right in South Africa mixes politics and religion, and seeks to exploit popular grievances to garner support for the creation of a secessionist Afrikaner state. The South African white right does not have the resources, capacity, or support to successfully execute a coup d'état. The Boeremag serves as a reminder, however, that the extreme right can create instability and destruction on a significant scale in South Africa.
