大国战略竞争与美国对华技术政策变迁

世界政治领导国的对外技术政策很大程度上源于应对大国战略竞争的需要。当美国面临直接、迫切的大国战略竞争压力时,更愿意通过放宽技术进口和出口限制来争取合作者、应对竞争者,即"利用强者打败更强者"。自20世纪70年代以来,美国对华技术政策经历了从逐步放松再到加强限制这一过程。苏联的安全竞争压力迫使美国在加强对苏技术出口限制的同时,放宽对华技术出口限制。日本的经济竞争压力促使美国在加强对日技术进口限制的同时,放宽对华技术进口限制。应对直接、迫切的大国战略竞争压力,会促使世界政治的领导国更重视当期利益,同时也为潜在竞争者的成长提供机会。而当苏联和日本对美国构成的大国战略竞争压力逐渐褪去时,美国对华技术政策再度面临调整压力,以致于今为甚,通过发起对华贸易战,打压中国高新技术产业,全面收紧了对华高技术进出口限制。美国的技术竞争将是今后很长时间中国技术进步难以绕过的阻碍。     

Rejecting representation? Party systems and popular support for referendums in Europe

Under what conditions do citizens favor deciding political issues by popular vote? Models of support for popular vote processes usually consider the influence of individual attitudes such as political trust and interest in politics. But much less is known about the effect of institutional variables on support for popular vote processes. This article builds on research showing that disaffection with elected officials shapes support for referendums by considering the influence of the party system. First, an analysis of multilevel data from twenty-four European democracies indicates that individuals are more supportive of referendums in countries with fewer effective political parties. Second, a mediation analysis provides evidence that the number of parties influences referendum support through individual-level political trust and external efficacy. Where there are fewer viable parties, feelings that elected officials are unresponsive tend to increase popular support for referendums. These findings suggest a trade-off between available representation by political parties and support for direct influence over public policy.     

木丹颗粒对高糖环境下人血管内皮细胞Nrf2/ARE信号通路的影响

目的 探讨木丹颗粒对高糖环境下人血管内皮细胞核转录因子E2相关因子2（neclear factor erythroid 2-related factor 2，Nrf2）/抗氧化反应元件（antioxidant response element，ARE）信号通路及血管内皮生长因子（vascular endothelial growth factor，VEGF）的影响。方法 将健康雄性Wistar大鼠30只随机分为正常组、模型组、木丹颗粒组，每组10只，制备含药血清；将正常组含药血清加入正常糖浓度培养内皮细胞，模型组及木丹颗粒组分别加入高糖培养内皮细胞；采用RT-PCR、Western blot分别检测Nrf2、血红素氧合酶-1(heme oxygenase-1, HO-1)的mRNA及蛋白表达水平；采用ELISA法检测各组细胞上清液中VEGF含量。结果 与正常组比较，模型组Nrf2、HO-1的mRNA及蛋白表达均显著上调（P<0.05），VEGF的含量显著增加（P<0.05）；与模型组比较，给药组Nrf2、HO-1的mRNA及蛋白表达水平均显著上调（P<0.05），VEGF的含量显著减少（P<0.05）。结论 〖JP2〗木丹颗粒对高糖环境下人血管内皮细胞的保护作用机制可能与上调Nrf2/ARE信号通路的表达、降低VEGF含量有关。     

性犯罪药物防治入刑的正当性及本土形塑

近年来,我国性犯罪出现的一些新情况令人堪忧,需要探索新的治理政策。有的国家采取性犯罪药物防治作为性犯罪的治理手段,值得借鉴。性犯罪药物防治是利用口服或者注射药物方式减少罪犯的雄激素、降低其性欲,达到控制性犯罪目的。有人认为这是残虐、不人道的,侵犯身体健康与性权利。而性犯罪药物防治相比起物理阉割更具人道主义精神,有利于保障基本人权,其尊重受者自由意志,具备一定的社会容忍度,执行方式高效经济。但此种手段需要加以本土化改造,需要规范法律术语,明确刑法性质与适用对象,细化执行程序。     

战略、安全与国防财政治理

国家财政治理能有效推动国家经济建设与国防能力建设的协调发展。当前,我国外部环境正面临着复杂变化,要想改变“修昔底德陷阱”等固有观念,需要通过国防财政治理来提升财政在国防建设规划中的职能定位,持续强化财政战略规划统筹经济和国防的能力,及时消除潜在威胁,稳定地缘政治安全。国家战略、安全与国防财政治理天然地具有统一性,国防财政治理的效能越高,国家规划战略应对潜在安全威胁的选择性就越多,就越能巩固国家经济发展取得的成就。     

我国跨境民族语言认同研究的现状与展望

语言认同是一种复杂的文化心理趋同现象,是其它认同的基础,深刻地影响着人们的语言行为。跨境民族的国家通用语认同、民族语认同和外语认同直接关系到国家发展战略、边疆民族地区社会安全稳定和民族语言文化的传承与保护。我国的跨境民族多,但国内学者关于跨境民族语言认同的研究还很少。基于现有语言认同研究相关文献,本文分析讨论了语言认同的基本概念和跨境民族语言认同研究现状,并提出了未来研究我国跨境民族语言认同的路径和建议。     

Responding to Severe Parent–Child Rejection Cases Without a Parentectomy: A Blended Sequential Intervention Model and the Role of the Courts

There have been significant developments over the past two decades that have expanded our understanding of the dynamics of parent–child contact problems post‐separation, which have resulted in some changes in judicial processes to respond to these cases. One significant advancement is a more sophisticated differentiation of the nature and severity of contact problems, which better assists legal and mental health professionals to provide more suitable legal and clinical interventions. However, the issue of innovative court processes has received limited attention. The authors describe a subgroup of families within the “severe” category, for whom an expanded intervention model, referred to as a Blended Sequential Intervention is proposed. This approach involves a reversal of care with court mandated therapeutic support for the rejected parent and child, but also involves the favored parent in the therapeutic plan from the outset, and is intended to avoid a permanent “parentectomy” of the child from either parent. The authors discuss how the courts should respond to these cases, and posit that until all therapeutic treatments are exhausted, interim orders should be preferred to final determinations, and judges should maintain oversight. The authors discuss the critical role of judicial leadership in working with lawyers and mental health professionals to manage and address the issues in these high conflict cases.     

丝绸之路经济带建设中金融支持与保障研究

丝绸之路经济带建设坚持“政策沟通、道路联通、贸易畅通、货币流通、民心相通”的五通原则中,货币流通是基础和先导。开展金融合作不仅是经贸合作的基础,而且也是顺应金融市场全球化和金融监管国际化的内在要求。从微观、中观和宏观三个角度阐述金融在丝绸之路经济带建设中的支持作用,分析丝绸之路经济带建设中的金融支持面临的各种挑战,建议从开发性金融为先导引领区域金融支持;拓展人民币结算和扩大互换规模,推进区域性金融支持;推进国内金融机构的国际化水平;发展互联网金融,创新金融支持模式;建立丝路区域性国际金融中心;加强国际金融治理以及金融监管协调合作。     

双向汲取:社区社会组织的行动路径分析

社会组织是推动国家治理体系和治理能力现代化的重要力量。聚焦社会组织行动策略研究,能够更好地揭示外部制度环境制约下的社会组织参与基层社会治理的微观运行机制。运用"制度环境-行动策略-行动目标-行动任务"的分析框架,着重探讨社会组织与基层政府、社区居委会、社区居民之间的复杂互动关系,剖析复杂制度环境下社会组织行为策略选择及其多元化行动路径。S市G组织的个案研究表明,G组织通过"双向汲取"的行动策略能够实现社会组织行政性目标与社会性目标的双重目标达成。由于G组织接受任务的不同行动目标来源以及不同任务之间的相关性程度差异,使得G组织"双向汲取"行动策略呈现出复杂制度结构约束下的多元化行动路径。     

Peace-building Through Space-making: The Spatializing Effects of the African Union’s Peace and Security Policies

ABSTRACT

This article is discussing how the peace-building practices of the African Union have distinct ordering and space-making effects. Taking a socio-spatial perspective, it is argued that the peace and security projects through which the African Union, as a spatial entrepreneur, is addressing the scourge of ‘terrorism and violent extremism’ are geared towards (re-)establishing sovereignty that member states have lost in the past over their territories. While the African Union is favouring a spatial format that could be called ‘multiple networked regionalism’, the actual socio-spatial orders that are emerging around Africa’s transregional conflicts are far less clear cut.
