Comprehensive Summary Four heterometallic rare earth(Ⅲ)-cobalt(Ⅱ)complexes(rare earth=Y(1),Sm(2),Nd(3),La(4))stabilized by an o-phenylenediamine-bridged tris(phenolato)ligand(L)have been synthesized and *** these tetranuclear complexes,one polydentate L coordinates to one rare earth(Ⅲ)ion,and one cobalt(Ⅱ)ion,respectively,while two rare earth ions are bridged by four acetate *** complexes were applied in the copolymerization of cyclohexene oxide and CO_(2),which showed good activity(TON up to 440)and high poly(cyclohexene carbonate)selectivity(>99%).Kinetic studies determined the equation as rate=k[CHO]1[CO_(2)]0[initiator]1,which proves a first-order dependence on initiator concentrations and implies a synergistic mechanism with rare earth and cobalt ions cooperating in epoxide ring-opening and chain propagation.

BACKGROUND ： Digital subtraction angiography （DSA） is always regarded as the golden standard for diagnosis of intracranial aneurysm; however, the procedure is complex, traumatic, expensive and easy to induce vascular complication. Three-dimensional computed tomography angiography （3D-CTA） can make up deficiencies of DSA; therefore, it is used in clinical therapy wider and wider. OBJECTIVE ： To evaluate the clinical effect of 3D-CTA on disruption and hemorrhage of intracranial aneurysm pre- and post-operation and compare with the effect of DSA. DESIGN ： Auto-control contrast observation SETTING ： Department of Neurosurgery, Shengjing Hospital of China Medical University PARTICIPANTS ： A number of 106 patients with disruption and hemorrhage of intracranial aneurysm were selected from the Department of Neurosurgery, Shengjing Hospital of China Medical University from January 2003 to April 2006. All patients were diagnosed with cranial operation and consent. There were 47 males and 59 females aged from 3-76 years with the mean age of （47±13） years. Among them, 82 patients had extensive subarachnoid hemorrhage （SAH）, 7 had hemorrhage at longitudinal fissure, and 17 had hemorrhage at ambiens cistema and lateral fissure. Moreover, intraventricular hematocele was accompanied on 13 patients and hematom on 9 patients. METHODS：（1） 3D-CTA examination： Siemens SOMATOM Sensation 64 CT was used in this study. The thickness was 1 mm and interval of reconstruction was 0.8 mm. Localizing section was plainly scanned as the standard of canthus line. Scan ranged from 30 mm below sella to 50 mm above sella. Non-ion contrast medium of Omnipaque 350 （concentration of iodine was 350 g/L） was inserted into anterior vein of elbow with 18G trochar retained with high-pressured injectoc pum. The speed was 4.5 mL/s and the total volume was 80-100 mL with the means of 90 mL. Scan started at 10-20 s after injection of contrast medium. Original image was dealt with Leonardo workstation an

哈贝马斯为实现历史唯物主义全面解释社会进化的目标,重新阐释了唯物史观及其基本范畴,尝试以交往行为理论克服思辨哲学的理论范式,为把握当代资本主义社会提供了新的视角。哈贝马斯的批判理论展现出了其在当代境遇中重建历史唯物主义的理论建树,但他通过语言建构的理想交往模式并没有深入到社会存在领域。由于未能彻底从意识内在性的思维范式中抽身,哈贝马斯误判马克思的主体概念仍旧属于认知主体的范畴。他不曾洞见主体概念只能由感性活动来定向——主体在感性活动中的自我生成,也无法领会主体的解放正是通过感性活动才得以实现。因此,哈贝马斯在解读马克思的主体概念时,构建的交往主体概念仍然局限于意识领域,未能触及社会现实。

地方政府的经营模式具有动态性、多样性和适应性特征。文章构建了一个经营风险、预算约束与控制权分配的分析框架,并借助案例研究解释开发区经营模式从市场外包到政企统合再到政企合作的演变。研究发现,这一演变是地方政府依据不同发展阶段的经营风险和预算约束等因素对控制权的相机分配。具体而言,从市场外包模式向政企统合模式的演变是地方政府转移控制权、进行纵向整合的过程,目的是解决市场企业与地方政府的经营冲突,降低经营风险。从政企统合模式向政企合作模式的演变,是地方政府在保留相机控制权的基础上向市场让渡部分权力、与市场合作的过程,目的是降低经营成本,缓解预算约束。控制经营风险,保障投引资目标是首要逻辑。在此前提下,地方政府通过相机调整控制权来降低经营成本、缓解预算约束。不同发展阶段、不同治理领域的风险、约束和成本的变量特征决定了行政与外包两种机制的组合配置,从而塑造了多样的经营或治理模式。

从历史比较来看,从经营企业到经营辖区,地方政企关系发生着新的变化。以地方政府的土地经营策略为观察视角,发现地方政府的土地经营存在着"分类经营"的特征,并分别反映了市场中的"买卖"逻辑和"入股"逻辑。依此进一步发现,从经营企业到经营辖区,政企关系虽然仍具备不同程度的"统合性"特征,但形成机制和关系性质已从以地方威权为基础的行政干预型统合关系转向了"以地入股"形成的市场合作型统合关系。而以企业改制和产权改制为基础的民营化,开放与垄断并存的生产要素市场,政治和市场中的双重竞争和互嵌等制度环境共同形塑了这一转变。
