关于转型期企业共青团建设的几点思考

企业团组织引导青年发展,应基于青年特点和企业的实际展开。企业团组织要发挥政治上引领青年、帮助青年成才、对青年的考核等方面的作用。企业团建工作要从健全组织机构、介入企业文化、推进组织创新、规范组织生活、开展青年养成教育等方面入手。     

Digital Wiretap Warrant: Improving the security of ETSI Lawful Interception

Lawful Interception (LI) of data communications is an essential tool for Law Enforcement Agencies (LEA) in order to investigate criminal activities carried out or coordinated by means of Internet. However, the ability to secretly monitor the activities of citizens also has a great impact on civil rights. Therefore, democratic societies must prevent abuse and ensure that LI is only employed in specific cases with justifiable grounds or a probable cause. Nowadays, in many countries each interception must be authorized by a wiretap warrant, usually issued by a judge. However, this wiretap warrant is merely an administrative document that should be checked by the network or service operator before enabling the monitoring of its customers, whose communications are later handed over to a LEA in plaintext. This paper proposes the idea of employing a Digital Wiretap Warrant (DWW), which further protects the civil liberties, security and privacy of LI by ensuring that monitoring devices can only be enabled with a valid DWW, and by encrypting the captured data so only the authorized LEA is able to decrypt those communications. Moreover, in the proposed DWW framework all digital evidence is securely time-stamped and signed, thus guaranteeing that it has not been tampered with, and that a proper chain of custody has been met. In particular this paper proposes how to apply the DWW concept to the lawful interception framework defined by the ETSI LI Technical Committee, and evaluates how the additional security mechanisms could impact the performance and storage costs of a LI platform.

米尔斯基和他的《俄国文学史》

"公爵同志"米尔斯基是20世纪二三十年代欧美和苏联文学界、知识界的重要人物之一,他充满突转的生活经历和坚忍不拔的文学活动构成文坛的一段传奇,甚或那一代俄国知识分子之命运的缩影和象征。他用英文撰写的《俄国文学史》被纳博科夫称为"用包括俄语在内的所有语言写就的最好一部俄国文学史",所谓"米尔斯基文学史"因其"折中主义"的文学史观、主客观统一的批评手法和极富个性的话语风格而独树一帜,被视为西方俄国文学研究的奠基之作,长期被欧美高校斯拉夫系用作俄国文学史教材,其影响历久不衰。     

The Management of Democratic Elections in Africa (MDEA) programme at the university of South Africa: Is this the right path towards African solutions?

There have been a number of initiatives in Africa to rid the Continent of political instability, conflict, poverty and disease. Many have argued that aid from the West has helped Africa in many ways—from stopping wars, to food relief and rescuing the African environment. Yet others have slated Western involvement which they contend, frequently leaves Africans dependant rather than capable of solving their own problems. In line with the pan-Africanist and the African Union (AU) ideals, there is now a realisation by Africans that there is a need to find African solutions to African challenges and problems. This review article explores the University of South Africa’s (Unisa’s) Management of Democratic Elections in Africa (MDEA) programme, by looking at its objectives and the reason why it must be labelled a Programme, its mandate, which is in line with the brief of the AU and pan-Africanist ideals. The article focuses on how Unisa’s programme responds to the African Charter on Democracy, Elections and Governance (ACDEG); and how it has attempted to facilitate knowledge for peace in Africa, through empowering electoral officials from various African states. The article concludes by looking at the successes and limitations of the Programme over a five-year period, from its inception in 2011.     

广东省猪源葡萄球菌耐药性分析及多重耐药基因cfr的流行现状

为了解2013-2017年间广东省猪源葡萄球菌的耐药情况及多重耐药基因cfr的流行现状,采集生猪养殖场和交易市场猪鼻腔拭子分离葡萄球菌,采用琼脂稀释法测定分离菌株对14种抗菌药物的敏感性,并用PCR检测mecA和cfr基因的携带情况。结果显示,在采集的4099份样品中分离到葡萄球菌1485株,其中金黄色葡萄球菌173株。猪源葡萄球菌对红霉素、四环素、泰妙菌素、克林霉素、沃尼妙林和氟苯尼考耐药严重,耐药率分别为91.0%、90.2%、87.7%、84.6%、84.6%及82.0%,对利福平和利奈唑胺相对敏感,未发现万古霉素耐药菌株;庆大霉素、四环素、红霉素和环丙沙星的耐药率呈现逐年上升的趋势。在1485株葡萄球菌中,mecA和cfr的检出率分别为39.9%和12.3%。cfr阳性菌株常携带多种耐药基因,cfr基因的遗传背景也呈现多样化。结果表明,广东省猪源葡萄球菌的耐药情况严重,cfr的检出率高,应加强养殖业中抗菌药物的规范和合理使用,减缓耐药性的产生和传播。     

山羊支气管肺炎的计算机断层扫描影像研究

为了研究山羊支气管肺炎的计算机断层扫描(CT)影像表现,将10只山羊随机分为2组。试验组、对照组各5只,试验组通过气管内注射血清A型多杀性巴氏杆菌标准菌(4×10^8CFU/mL)人工诱发山羊的支气管肺炎,对照组注射等体积无菌PBS;观察接种前、后各组山羊的临床症状、体温及全血白细胞数等指标,并同时在接种前和接种后第1、3、5天对胸部进行CT扫描,比较两组影像学差异,观察山羊肺部病理解剖学变化。结果显示:接种前后体温、全血白细胞数差异显著;对照组CT影像接种前后未见异常;试验组影像多见两侧肺叶中下部呈现大小不等的片状或结节状的类似软组织密度影,边缘不清,肺纹理紊乱且模糊,支气管壁增粗,支气管扩张,呈"树芽征"及"轨道征"。结果表明,经气管内接种巴氏杆菌能够成功诱发支气管肺炎,CT影像与山羊支气管肺炎的临床表现密切相关,对山羊支气管肺炎的诊断具有较好的敏感度,有利于鉴别,应成为其较早期诊断的依据之一。

沿海十省(市)药品监管机构能力之比较研究

在构建社会主义和谐社会的当代中国,药品的安全性和有效性正日益引起人们的关注,而药品监管机构能力的建设与评估也开始成为社会监管领域的重要问题.通过回顾国内外已有的对政府能力概念和要素的研究,借用Nelissen的潜在能力和现实能力理论,结合世界银行2003年《世界发展报告》中对机构现实能力的要素分析和"行政储备"理论对机构潜在能力的要素分析,构建起药品监管机构能力的结构模型,并提出一套评估的指标体系.对数据进行标准化处理后,通过统计排序对沿海十省(市)药品监管机构能力进行评估和比较,进而利用最小二乘法(OLS)建立回归模型,分析潜在能力中的财力和人力因素对现实能力的贡献率.研究发现:地区财力对监管机构现实能力的影响较之人力因素要大,这在理论和实践中都可以得到证实;各地药品监管机构的潜在能力与现实能力之间存在较大差异,就那些现实机构能力较低的地区而言,现阶段有必要把工作重点放在医药企业生产经营行为的监管和农村地区医药监管基础设施的建设上;而对于潜在机构能力较低的地区来说,从"专业化、程序化和独立性"等方面提升机构整体的人力资源是当务之急.
