美国巡警体制对我们的启示

美国的巡警体制有利有弊。巡警在美国社会治安中扮演着十分重要的角色,该警种数量约占全美警察的60%以上,基本上从事第一线的巡逻勤务工作,他们的警用装备精良,但是因其属于地方组建的警种,参加全国统一行动的协调机制较弱。新中国创建的巡警队伍仅10余年历史,尽管各地巡警的组织和装备存在差异,从事一线工作的巡警人数平均不到全国警察的10%,但由于中国巡警从中央到地方实行垂直领导,因此参与全国统一行动的协调机制较强,在当前防控街面犯罪、维护社会治安等方面发挥了应有的职能作用。比较研究中美两国的巡警体制,是为了掌握国外警务动态,取长补短,进一步改革和完善中国的巡警体制。     

浅论加强未成年人思想道德建设的重点和规律

加强未成年人思想道德建设是我们党和政府、全社会必须高度重视的一项工作。文章认为,在当前转型中国,我们仍应进一步认识加强未成年人思想道德建设的重要性和紧迫性,深刻把握加强未成人思想道德建设的方针和重点,努力探索加强未成年人思想道德建设的规律性,切实有效地做好我国未成年人思想道德建设工作。     

Differentiation of Antemortem and Postmortem Appendicular Fractures Using Magnetic Resonance Imaging Signal Intensity Changes in Bone and Soft Tissues,

Intraosseous T1-weighted (T1W) and short-tau inversion recovery (STIR) magnetic resonance imaging (MRI) signal intensity changes—so-called bone marrow edema—may be able to differentiate antemortem and postmortem fractures in human forensic imaging. The primary objective of this study was to investigate this hypothesis using an animal model. Three juvenile Landrace pigs were anesthetized and underwent MRI of both tibiae and both radii using a 1.5 T magnet. T1W, T2-weighted (T2W), STIR, and T2* sequences were included. Antemortem fractures were induced in both tibiae and postmortem fractures in both radii, and MRI was repeated. Two board-certified radiologists blinded to fracture group jointly evaluated the images for intraosseous and soft tissue signal intensity changes. Sensitivity (Se) and specificity (Sp) in identifying antemortem fractures were calculated based on intraosseous, soft tissue, and combined intraosseous and soft tissue signal intensity changes. Intraosseous and soft tissue signal intensity changes, when present, were hyperintense in all sequences. Intraosseous hyperintensity in T1W and T2W sequences yielded Sp of 100% for antemortem fractures. Regardless of sequence, soft tissue hyperintensity was comparatively more sensitive than intraosseous hyperintensity. Sensitivity for each sequence could be maximized by assessment of soft tissue and intraosseous hyperintense signals together; for the T1W sequence, such assessment optimized diagnostic utility yielding a Se of 100% and Sp of 83%. In summary, MRI—particularly the T1W sequence—can differentiate antemortem and postmortem fractures and may be a useful adjunct to the forensic analyses of fractures.     

Sustained Outcomes? an Exploratory Study of Juvenile Drug Courts and Long-Term Recidivism

This exploratory study examined juvenile drug courts’ effect on adulthood recidivism. Utilizing a twelve-year average follow up time, adult recidivism rates were compared between previous juvenile drug court participants and a comparison group of juveniles who participated in traditional probation. Linear regression models indicated limited recidivism effects of drug court on arrests or convictions into adulthood. The findings suggest that gender and race may play a role in how justice-involved juveniles interact and experience juvenile drug court, highlighting the need for gender-responsive and culturally responsive policies, practices, and programs within juvenile drug courts. Recommendations are made regarding future research areas and ways to potentially improve long-term juvenile drug court outcomes.     

屯堡文化研究

“屯堡人”是清代废明代卫所屯田制后对分布在贵州省黔中地区明初屯军后裔的专称,至今比较完整地保持着明代江南汉族文化的形式与内容。本文比较系统地分析叙述了屯堡文化的诸种特征。     

从反核威慑战略到最低核威慑战略:中国核战略演进之路

当前学者们对中国核战略的争论焦点在于,没有任何一种现有核战略定义能够完全涵盖中国核政策的特点。本文认为,正确理解中国核战略,需要摆脱现有核战略理论概念体系的束缚。只有从中国核战略产生和发展的具体时代背景中寻找线索,才能认识到,中国核战略经历了从反核威慑战略到最低核威慑战略的巨大转变,而中国长期大规模备战核战争遗留下来的物质遗产和思想基础,仍然对中国核战略产生着巨大的影响力。中国学者应从中国核战略实践出发,参与构建主流话语体系,为核战略学科建设做出自己的贡献。     

全球减排路线图的正义性——对胡鞍钢教授的全球减排路线图的评价与修正

任何全球减排路线图的绘制都无法脱离国际正义而具有生命力。气候变化问题的特性要求全球减排路线图尊重具有两面性的国际气候正义:环境正义和发展正义,需要考虑国家间公平、人的公平和代际公平。仅以人类发展指数(HDI)作为衡量国家承担减排责任的标准缺乏足够的正义,至少还需要加入人均历史累积排放和气候变化脆弱性两个指标。三者分别体现气候变化正义性中的人的平等发展权、减排责任分担和对受害者在排放权上的补偿。综合三大指标后的四分组分类,才是更体现正义性、更容易被接受和执行的路线图。从正义性出发,中国应承担相应的减排责任,并努力推动全球减排进程,但也要注意维护自身的发展权益。中国在全球减排中的作为,应是在国际正义与国家发展战略间取得平衡。     

半嵌入性互动治理的形成逻辑与主要类型——以H街道四个社区的业委会与物业管理运作为例

城市基层治理涉及多元治理主体的复杂互动关系,这种复杂的互动关系内蕴着权力结构与秩序的演变。国家、市场、社会三方主体力量在中国强国家弱市场弱社会的现实背景下,呈现出以结构性非对称性形式相互依赖、三角权力关系稳定、相互弥补各方失灵为特点的互动形态。文章将此互动形态在基层社区中的运作概括为“半嵌入性互动治理”。基于国家-市场-社会三维分析视角,通过多案例比较方法研究H街道四个社区的业委会与物业管理运作,发现“半嵌入性互动治理”在现实运作中呈现多种类型。国家、市场、社会在基层社区治理中的互动关系会根据现实需求与权力博弈进行平衡与调试,最终保证社区内部安全与有效治理。     

20世纪末以来中、美与东盟的三边互动关系——以权力转移为视角

中国的崛起对美国和东盟均产生重大影响,导致中、美和东盟在经贸、政治和认知方面形成了互动关系。由于经济领域的区域经济一体化、贸易转移效应和政治领域东亚一体化的排斥效应等因素,中美在东亚的权力关系发生了转移,东亚秩序经历了结构性调整。三方在经贸、政治和认知的互动相互影响并呈正相关关系,使得东亚的权力转移在和平中实现。互动中仍存在一些问题需要三方调适和合作加以解决。
