经济手段在南部非洲发展共同体环境管理中的运用及启示

南部非洲发展共同体为根除贫穷和解决生态恶化问题需要寻求以可持续发展为导向、以促进共同实现经济效益和环境效益为目标的环境管理手段。作为一种市场激励手段,经济手段进入南共体环境管理的视野,并被广泛地运用于这一区域土地资源的管理和使用,水资源的使用、分配和管理以及工业部门中。南共体有关环境管理中经济手段运用的实践对于我国环境管理的革新同样具有一定的借鉴意义。     

中越边境区“两国共市贸易区”合作模式探析——以中国东兴市为例

经济全球化和区域经济一体化的发展为边境区合作创造了良好机遇。中国东兴市处在边境经济理论创新与跨境合作模式创新的前列,完全有必要和可能利用其独特的天时、地利、人和,与越南发展推动"北部湾经济圈"及"中国—东盟自由贸易区"的跨境共同市场与商贸服务平台。文章通过对构建中国东兴—越南芒街"两国共市贸易区"的边境区合作模式进行可行性分析,提出中国东兴—越南芒街"两国共市贸易区"合作模式运作的建议。     

International institutions and credible commitment of non-democracies

How do non-democratic countries credibly commit to policies in front of domestic and international audiences? Unlike democracies, non-democracies do not have functioning electoral systems and free presses to make their commitments costly thus credible. Yet, the need to credibly commit to a policy arises for non-democracies as well. In particular, when non-democratic leaders push for economic reforms, they need to coordinate the beliefs of domestic groups and attract international resources. How do non-democracies solve the commitment problem and succeed in achieving their policy goals? In this study, we argue that international institutions provide an important mechanism through which non-democratic countries could credibly signal their commitment to open economic policies. We test the argument with the involvement of IMF programs by post-communist countries from 1989 to 2005. We find that while IMF status is used as a credible commitment device for all countries, the effect is more significant for non-democracies.     

绵羊卵母细胞的差异蛋白质组学研究

为了研究绵羊卵母细胞成熟过程中蛋白质的表达模式,以期在蛋白质水平探索绵羊卵母细胞成熟的分子机制,将采用双向凝胶电泳技术获得的2-DE图谱经PDQuest8.0分析并找出差异蛋白斑点后,对差异蛋白斑点进行高效液相色谱串联离子阱质谱分析。结果显示,GV期和MⅡ期卵母细胞2-DE图谱之间存在13个表达差异明显的蛋白斑点;4个蛋白斑点的质谱检测结果较为理想,对应3种不同的蛋白质,分别为截短的VP2、苹果酸脱氢酶、谷胱甘肽转移酶M3;其中截短的VP2、苹果酸脱氢酶在卵母细胞成熟过程中表达量下调,谷胱甘肽转移酶M3在卵母细胞中大量表达并且表达量上调。结果表明,绵羊卵母细胞成熟过程中,细胞的mRNA合成和表达水平以及糖代谢水平可能降低,细胞的抗氧化和解毒能力可能提高。     

伪满《组织法》解析

伪满洲国成立后很快构筑了基本法体系。伪满基本法中,规定政府机关职能及其相互关系的《组织法》处于核心地位。本文重点分析了《组织法》对傀儡政权的政治设计。作者认为:日本殖民者设置"参议府"是为了防止立法权和行政权出现独立的倾向;虽然《组织法》包含着权力分立的原则,但实际上立法权、监察权均是行政权的点缀;伪满政权立法迅速,但并不周详,《组织法》的个别条款存在混乱和矛盾。     

东亚一体化与中国的东亚战略

本文在总结东亚一体化建设历程与成就的基础上,重点分析了东亚一体化面临的内外挑战。基于东亚一体化存在的问题、前景的不确定性以及正在急剧演变的东亚地缘政治格局,中国未来的东亚战略应该重新构建,其中尤其需要注意充分估计中国崛起效应,不断优化中国对外战略,进而超越东亚一体化,在大国关系的互动特别是中美关系的良性互动基础上推进区域合作,从而使新的东亚战略符合东亚国际关系的特点。     

猪繁殖与呼吸综合征病毒的免疫学研究进展

从猪繁殖与呼吸综合征病毒的主要抗原蛋白、持续性感染、细胞免疫、体液免疫和免疫抑制几方面论述了猪繁殖与呼吸综合征病毒与宿主之间存在复杂的免疫相互作用,旨在为猪繁殖与呼吸综合征疫苗的设计与研制提供新的思路和方法。     

国际政治经济学美英学派的论战——学术分野、国家地位与中国议题

历史传统、学术文化与国际地位的差异导致了国际政治经济学美英学派之间明显的学术分野。英国学派更具有体系与制度的批判精神,美国学派主流理论霸权护持心态较为明显。在2008年爆发的全球金融危机面前,美国学派处于普遍失语状态,而英国学派则给予了及时、建设性的学术反应。中国学术界必须清算美国学派的不适当影响,建立更具广泛性的借鉴性知识体系,提出更多具有创造性的中国议题与中国命题。     

乳酸菌对子宫内膜上皮细胞的黏附及其对致病菌的拮抗作用

以永生化山羊子宫内膜上皮细胞作为体外模型,采用革兰氏染色法观察乳酸菌和致病菌对子宫内膜上皮细胞的黏附特性;通过平板计数法观察乳酸菌对致病菌的黏附拮抗作用.结果显示,嗜酸乳杆菌、粪肠球菌、盲肠肠球菌对子宫内膜上皮细胞均表现出很强的黏附特性,黏附细菌数分别为每个细胞87、45、34个.黏附拮抗试验显示,3株乳酸菌均使致病菌...     

The Status and Characteristics of Couple Violence in China

A couple’s relationship is very important to marital well-being as well as the harmony of family and society. Violent behaviors in marriage have bad effects on people’s physical and mental health and cause large social burdens. In this study, we investigated 194 couples in Beijing to explore the status and characteristics of couple violence from three aspects by using Revised Conflict Tactics Scale (CTS2). We conclude that: (1) Couple violence is universal, although the frequency is not so high. Prevalence and frequency of psychological violence are higher than physical and sexual violence; rate of wives’ victimization is significantly higher than that of husbands; frequency of the perpetration of sexual violence by husbands is significantly higher than that by wives. (2) There is concurrence of different types of couple violence. Specifically, physical and sexual violence are usually accompanied by psychological violence; however, psychological violence exists independently. (3) Couple violence is often bidirectional, especially in psychological violence. (4) Marital length is negatively correlated to wives’ perpetration of physical violence and their victimization of sexual violence.
