公共租赁住房——夹心层的保障性住房   总被引:2,自引:0,他引:2  
作为我国城市住房保障体系的后起之秀,公共租赁住房在准入门槛、保障模式、运营方式、房源适配性等诸多方面对现有住房保障制度进行了机制再造。但它在运行过程中也存在一些突出问题,如前期准备不充分、缺乏法律保障、准入把关不严、退出机制不健全等,使得其住房保障作用难以有效发挥。为提升该制度对城市中低收入住房困难群体的保障作用,我们应当通过健全机制和创新制度,消解该制度运行过程中存在的不足之处,大力推进公共租赁住房保障制度的发展。  相似文献

吴越文化在历经东周方国覆灭、民族大离散之后,由于话语权的缺失,其自身除了地域因素之外在物质意义上的文化传承能力基本丧失,而掌握着绝对话语权的中原文化解释系统对其的外部叙事却在某种程度上为吴越文化的传承在文献上连接起了这中断的一环。中原外部叙事一方面保存、还原了某些吴越文化的真实面貌,另一方面也自然而然地流露出了以“礼制”为文化解释核心的中原文化立场叙事框架下的认同重构与文化整合意识,表现出一方面极尽对吴越文化的歧视与排斥,另一方面却又积极寻求对某些文化共性的吸纳的双重姿态,吴越文化的东周转型正是在排斥与吸纳的双重叙事的中原文化认同重构与文化整合之下完成的。  相似文献

This study focuses on the examination of stable isotope biomarkers in human fingernails of travelers who ventured away from Salt Lake City, UT and subsequently returned. Here, we describe three case studies examining: individual travelers (n = 4), paired travelers (n = 2), and a traveler (n = 1) who repeatedly left and returned. Our case studies examined the influences of dietary and drinking water inputs on fingernail stable isotope profiles for reconstructing travel histories. Stable isotope data were compared with theoretical and predictive models that laid the groundwork for anthropological and forensic geospatial reconstruction of travel histories. Drinking water inputs strongly influenced stable isotope profiles and the patterns observed were consistent with reported travel histories. Finally, observed fingernail stable isotope ratio data were consistent with modeled rates of stable isotope turnover and transition to expected values for the new environment. The results of our study further support the use of fingernail tissues for travel history reconstruction.  相似文献

Photographic surveying is fundamental to crime scene investigation. It is performed using 2D images; however, this method is limited because it does not offer a detailed view. We present a 3D (three‐dimensional) experimental model that has clarified unsolved aspects of a homicide. A woman was found dead in her home. Considering the large number of injuries on the victim, signs of the use of two weapons, and the absence of traces of the killer/s, several hypotheses about the dynamics and the number of offenders were made. The forensic surveys suggested that a single offender had used two weapons at the same time, but this hypothesis was considered to be impossible by investigators. Our 3D model allowed us to experimentally reproduce the murder and compare various dynamics. The model was used as evidence in Court to prove the hypothesis of a single killer and demonstrate that no other people were involved.  相似文献

When reconstructing a bullet's trajectory prior to impact using the spatial orientation between two consecutive bullet defects (e.g., by probing), it is important to take the bullet's deflection into account. The (critical) ricochet angles as well as the vertical and horizontal deflection angles of eight cartridge types on laminated particle board have been studied. For all eight of the cartridge types combined, the critical ricochet angles lie between approximately 14° and 26°, while for the subgroup of the jacketed bullets, this range lies lower, between approximately 14° and 18°. The data from this study can be used to assess the accuracy and precision of the applied method. The results show that the highest deflection angles are seen near the critical ricochet angle. Generally speaking, vertical and horizontal deflection angles can almost be neglected above angles of incidence of 30° or 40° for handgun ammunition when shooting at laminated particle board.  相似文献

This ballistics study examines whether saline breast implants can decrease tissue penetration in firearm injuries. We hypothesize that the fluid column within a saline breast implant can alter bullet velocity and/or bullet pattern of mushrooming. The two experimental groups included saline implants with 7.4 cm projection and a no implant group. The experimental design allowed the bullet to pass‐through an implant and into ballistics gel (n = 10) or into ballistics gel without passage through an implant (n = 11). Shots that passed through an implant had 20.6% decreased penetration distance when compared to shots that did not pass‐through an implant; this difference was statistically significant (31.9 cm vs. 40.2 cm, p < 0.001). Implant group bullets mushroomed prior to gel entry, but the no implant group mushroomed within the gel. Bullet passage through a saline breast implant results in direct bullet velocity reduction and earlier bullet mushrooming; this causes significantly decreased ballistics gel penetration.  相似文献

目的对有参考个体参与的单亲祖孙关系鉴定中家系基因型重建方法的应用及计算思路的选择进行探索研究。方法依据河北汉族人群38个常染色体短串联重复序列遗传学数据,用计算机模拟8000个祖孙家系,选择生母及不同数量父辈个体作为参考样本进行单亲祖孙关系鉴定,应用家系基因型重建法的三种不同计算思路:期望值法、最小概率值法及改良的最小概率值法计算祖孙关系指数(grandparent index, GI),通过诊断实验设定累积祖孙关系指数(combined grandparent index,CGI)界值,并用60例实际案例进行验证。结果父辈参考个体数目显著影响单亲祖孙关系的判定,随着参考个体数目的增加,判定的准确性增加。若以104、10-4作为认定与排除的界值,即使只有1个父辈参考个体,期望值法获得的判定准确度也在90%以上,2个父辈个体参与时准确度达99.8%,而最小概率值法的灵敏度较低,假阴性率较高,改良的最小概率值法介于二者之间。60例实际案例验证结果显示,以期望值法计算CGI值,除有一个单参考个体真家系不能判定外,其余家系均被准确认定或排除。结论在单亲祖孙关系鉴定中,生母及父辈个体参与鉴定时,应用家系基因型重建法可以有效利用更多被检个体的遗传信息,提高鉴定效力;在讨论的三种计算思路内,期望值法能更准确的估计亲缘关系成立的可能性,其效力和安全性均足以满足该类鉴定需求。  相似文献

"日台条约"与战后日台关系框架的确立   总被引:1,自引:0,他引:1  
本文从历史学实证研究的角度,考察战后"日台条约"签订的过程,认为"日台条约"奠定了战后日台20年官方关系的基本框架,它不仅对日本与台湾而且对亚太地区都发生影响,可以说"日台条约"是战后日台关系的基础工程;如果从更为广阔的时间范围来看,该条约可以看作是蒋介石试图建立"亚洲反共联盟"的重要组成部分.  相似文献

试论我国刑事再审程序的缺陷及其制度重构   总被引:1,自引:0,他引:1  
在传统的诉讼实体真实主义理论的指导下,我国的刑事再审程序在制度设计上呈现出诸多缺陷。“无限申诉、无限再审”再审模式严重窒息着我国司法权威的生成并动摇着人们对司法的信任和尊重。用现代司法理念具体分析了我国刑事再审程序所存在的问题,并对其制度重构提出了自己的建议。  相似文献
