From environmental policy concepts to practicable tools: Knowledge creation and delegation in multilevel systems

The problem‐solving capacity and problem‐generating potential of multilevel systems entail the need for the delegation of authority. When the problem concerned is about how to put an abstract policy concept into a practicable policy tool, the choice of the respective delegation trajectory depends on the policy models or the policy‐relevant knowledge that the respective political levels can supply. When regarding the European Union (EU) level as the starting point of knowledge creation and delegation trajectories, and concentrating on transaction costs, policy knowledge and models generated at the international level provide the most cost‐effective solution. Only when the international level is not able to provide further policy knowledge and innovation does the EU delegate its definitional authority, first downward to the member states and then sideways to EU agencies. We illustrate the plausibility of our dynamic understanding of multilevel governance by using Environmental Policy Integration as an example.     

共同富裕目标下相对贫困治理的逻辑与机制

我国贫困问题的主要形态已从绝对贫困转向相对贫困，顺应相对贫困治理的需求，有必要系统构建贫困治理的逻辑与机制。在分析相对贫困的概念、特征和治理需求的基础上，文章从系统观念出发，提炼并阐释了以党领导为核心，以自治、法治、共治和技治为手段的“1+4”相对贫困治理逻辑。通过分析浙江安吉“生态扶贫”和山西“吕梁山护工”治理实践表明，由于地方推动共同富裕的基础条件具有差异性，治理的侧重点会有不同——安吉重视绿色发展理念和共同富裕示范机制建设，吕梁重视护工就业培训和脱贫增收机制构建，但其治理逻辑存在共识，能有效地将中国特色社会主义的制度优势和党的领导优势转化为地方治理效能。基于此，文章在“1+4”相对贫困治理逻辑基础上结合地方经验，从组织机制、内在动力机制、法律机制、协同共治机制、监测机制、示范引领机制六个方面提出贫困治理长效机制的基本框架，尝试为全国推动共同富裕提供理论指引。     

Exploring the Relationship Between Childhood Sexual Abuse and Adult Sexual Perpetration

Empirical findings indicate that many adult sexual offenders experienced sexual abuse during childhood. It has been suggested that characteristics of offenders' sexual perpetrating behaviors may resemble their own victimization experiences, although there has been minimal empirical investigation in this area. The purpose of the present study was to provide preliminary data on the relationship between childhood sexual abuse and characteristics of sexual offending behavior. A sample of adult male sexual offenders with histories of sexual abuse completed the Sexual Victimization Survey as well as a measure on their sexual offenses. Such characteristics as the nature of sexual activities, duration and frequency of experiences, and age and relationship of participants were examined. Results showed trends in the hypothesized direction and revealed a variety of similarities between childhood sexual abuse and adult sexual perpetration. Findings of this exploratory study suggest the importance of addressing the nature of victimization in the treatment of sexually abused boys and offenders with histories of sexual abuse.

在俄罗斯远东地区，有众多的中国人在那里经商、兴办实业、承包土地和工程，并为当地人提供工作岗位。他们推动了远东地区的经济发展，以自己的行动赢得了俄罗斯人的信任与尊重。     

猪ERK6基因编码区的克隆及组织表达谱分析

利用RT-PCR方法扩增了猪ERK6基因编码区的序列,将扩增产物与pMD18-T载体连接,构建了重组质粒;重组质粒经PCR、酶切鉴定后进行测序;采用Northern杂交和半定量RT-PCR方法在猪不同部位骨骼肌中分析了ERK6基因转录本的个数、大小及组织表达谱。结果显示,所克隆的猪ERK6基因片段长1 113 bp,含有1个1 104 bp的开放阅读框(ORF),该ORF编码367个氨基酸;该基因与已报道的人ERK6基因核苷酸序列相似性为90%;猪ERK6基因在肌肉组织中只有一个转录本,大小约1.5 kb。此基因在骨骼肌中的表达量最高,心、子宫次之,卵巢最低;而在脂肪、胃、肝、脾、肺、肾、十二指肠和胰腺中未见表达。结果表明,猪ERK6基因与已报道的小鼠和人ERK6基因一样,主要在骨骼中特异表达。     

Congressional Dominance and the International Trade Commission

This study examines the unfair trade decisions of the InternationalTrade Commission (ITC) and how they have been affected by Congress.It begins by identifying the means Congress can use to influenceITC decisions and then estimates both the extent to which thesemeans have been used and the extent to which they have shaped theITC's behavior. The study reaches two conclusions. First, Congresshas tried to shape the ITC's behavior, but it has not tried tomicromanage this behavior. Second, while the ITC's behavior hasbeen influenced by Congress, congressional influence is not asimportant as other factors, such as statutory criteria.     

一抹秀色壮晚霞——“靓妈模特篮球队”采撷

唱着<东方红>,穿着素朴纯棉衣服长大的那一代女人大都在做什么?吃药、买菜,抑或迈着踉跄的脚步跳街舞.一种集体无意识,使这些五六十岁的女人游走在霓虹和霓裳的边缘,望着都市烫人的力量喷发在她们下一代或又下一代的生命热源中.

氟对山羊成骨细胞增殖分化及钙化功能的调节

为探讨氟化物对反刍动物骨骼代谢的影响及对成骨细胞的作用机理,以初生山羊股骨骨膜为材料,采用半消化组织块培养法分离成骨细胞,进行传代培养,并通过形态观察、扫描电镜、碱性磷酸酶(AKP)和矿化结节染色进行鉴定。通过噻唑蓝(MTT)染色、AKP活性测定和钙化结节计数,研究不同浓度的氟对山羊成骨细胞增殖、分化及钙化的影响。结果表明,加氟48 h和96 h后,1.0×10-7~1.0×10-5mol/L氟可促进成骨细胞增殖,其中1.0×10-7及1.0×10-6mol/L氟与对照组差异极显著(P<0.01),高浓度氟(1.0×10-3mol/L)则抑制成骨细胞增殖(P<0.01);而1.0×10-4及5.0×10-4mol/L氟作用48 h对成骨细胞增殖无影响,作用96 h转而抑制成骨细胞增殖(P<0.01)。1.0×10-7~1.0×10-5mol/L氟能显著增强成骨细胞AKP活性及钙化能力(P<0.01),但氟浓度高于5.0×10-4mol/L时,AKP活性及钙化能力明显下降(P<0.01)。证实,低剂量氟能促进体外培养的山羊成骨细胞增殖分化及钙化,高剂量的氟则表现抑制作用。
