Postmortem chest computed tomography for the diagnosis of drowning:a feasibility study

It may be difficult to distinguish the cause of death in drowning cases without specific findings. The aim of this study was to explore the forensic value of thoracic postmortem computed tomography (PMCT) using routine images and three-dimensional (3D) image reconstructions. The imaging data of PMCT examinations of six drowning cadavers, aged 21–54 years, were analyzed. Twelve victims of sudden death from coronary artery disease (CAD) were chosen as a control group. After 3D bilateral lung images were reconstructed using image processing software, an interactive medical image control system was used to measure and analyze parameters including lung volume, lung volume ratio, mean CT value of the whole lung, and lung CT value distribution curves. Lung volume and lung volume ratio were used to assess the shape changes of the lung. Lung CT value distribution curves showed the corresponding number of pixels of the different CT values in the lung image. Lung volume was not significantly larger in drowning cases (mean 2 958 cm³) than in controls (mean 2 342 cm³). Lung volume ratio values in the drowning group (mean 0.3156) were greater than those in the control group (mean 0.2763); (P = 0.02). There was no significant difference between the drowning and control group in the mean CT value of the whole lung. There were differences between lung CT value distribution curves in drowning victims and controls, with drowning victims showing a single peak and CAD cases showing a bimodal distribution. Thoracic PMCT is helpful for the forensic medical diagnosis of drowning. Lung volume ratio and lung CT value distribution are potential indicators to distinguish between drowning and CAD.     

亚洲债券基金的推出背景、影响及发展方向

以银行信贷为主的金融体系使东亚地区面临两大问题,即巨大的金融风险和盈余资金利用效率低下,这也是亚洲金融危机中有关各方脆弱表现的直接原因。为了解决这两个问题或缓解其造成的危害,东亚各国(地区)纷纷提出方案,亚洲债券基金(ABF)作为一个阶段性成果,目前已经推出两期,分别为ABF1和ABF2。虽然亚洲债券基金在推动亚洲债券市场发展方面有一定的积极影响,但是其局限性也很明显,未来的发展方向主要是投资对象和投资主体的多元化。

上海大型居住社区高质量发展的理论分析与政策探讨——基于上海市五个大型居住社区的经验调查

本文基于上海市五个大型居住社区(以下简称"大居")的问卷调查与实地走访,梳理了上海"大居"现有就业机会、服务资源的配置情况以及居民需求状况。调查显示,上海"大居"在社区商业设施配套、公共交通设施、文体娱乐活动、物业管理服务以及教育资源等公共服务配套方面仍存在供需失衡问题,尚不能满足居民更高层次的需求。因而,要通过加快优质公共服务资源的导入,扭转"大居"弱势群体集聚的薄弱态势,推动人口结构优化,带动市场化资源的注入,培育"大居"社区内生增长动力,将"大居"建成多阶层、多群体共荣共享的高品质社区。     

How Many Seats in Congress Is Control of Redistricting Worth?

How large a benefit is partisan control of the redistricting process? Do legal constraints on redistricting—such as the preclearance requirement of the Voting Rights Act—alter this benefit? Are institutions designed to reduce the benefit to partisan control—such as redistricting commissions—effective? To measure the effects of partisan districting on the electoral fortunes of the parties, we collect data on the partisan composition of state government, House election outcomes, and moderating institutions over an 80-year period. Our results suggest that over time, both parties have benefited from unified control, with the effects largest in states where voters were evenly divided among the parties and smallest in states where the controlling party had a large advantage in the electorate. The effects have changed over time, with both parties having equally benefited from control during the middle of the 20th century, the benefit largely disappearing in the late part of the century, and the Republican Party seeing a moderate advantage from control in the current century. The benefits of partisan control were not diminished in states with redistricting commissions. The preclearance requirement appears to have hurt the Democratic Party except when its vote share was very low. The aggregate effects of partisan redistricting are moderate in magnitude—in the modern period, this effect has typically been less than 10 House seats, with the last election where control of the House would have flipped in expectation occurring in 1954.     

国家赔偿中民法规范的适用

《民法通则》第121条起初承担着确立国家赔偿责任的功能。在《国家赔偿法》实施前后,其分别构成了认定国家赔偿责任的基础规范和补充规范。民法规范在国家赔偿中仍然具有适用价值和空间。在赔偿范围上,公共设施致害赔偿、行政登记致害赔偿和瑕疵行政行为致害赔偿案件属于民事案件,全案适用民法规范;在责任分配上,法院通过适用侵权法上减轻责任、补充责任和连带责任规则,划定国家赔偿责任的范围;在时效上,《国家赔偿法》与《民法总则》的差异为民法规范提供了适用空间。

关于农产品供应链信任机制的探究

建立农产品供应链,降低农产品的成本,加强企业间的合作,培养企业间的信用是农产品供应链管理的核心。我国农产品供应链要想有大的发展,必须有现代化的流通商、超市系统、物流配送、运输、信息、仓储等各个方面的专业化经营的企业。应进一步建立农业产业集群与农产品供应链有效的信任机制。
