安全抑或自由: 危机中的美国宪法简

危机时刻是验证法治国家体制适应性的真正时机,由于美国宪法没有紧急状态条款,在南北内战、一战二战、反恐战争等紧急时期美国总统往往行使“超宪法权限”侵犯公民基本权利。为保证危机中的宪法依然有效,处理好国会立法与总统紧急权力之间的重大分歧,作为制衡者的法院需要对宪法进行更加审慎的解释,但其所表现出来的实用主义政治立场变换和共和紧急法制观的转型,揭示了非常态下美国宪法解释的核心问题：要自由的宪法还是安全的宪法？这也正是当下危机频发背景下每个奉行法治和保障人权的国家面临的共同难题。     

A Preliminary Investigation into the Accuracy of 3D Modeling and 3D Printing in Forensic Anthropology Evidence Reconstruction,

There is currently no published empirical evidence‐base demonstrating 3D printing to be an accurate and reliable tool in forensic anthropology, despite 3D printed replicas being exhibited as demonstrative evidence in court. In this study, human bones (n = 3) scanned using computed tomography were reconstructed as virtual 3D models (n = 6), and 3D printed using six commercially available printers, with osteometric data recorded at each stage. Virtual models and 3D prints were on average accurate to the source bones, with mean differences from ?0.4 to 1.2 mm (?0.4% to 12.0%). Interobserver differences ranged from ?5.1 to 0.7 mm (?5.3% to 0.7%). Reconstruction and modeling parameters influenced accuracy, and prints produced using selective laser sintering (SLS) were most consistently accurate. This preliminary investigation into virtual modeling and 3D printer capability provides a novel insight into the accuracy of 3D printing osteological samples and begins to establish an evidence‐base for validating 3D printed bones as demonstrative evidence.     

Constituent Communication Through Telephone Town Halls: A Field Experiment Involving Members of Congress

Telephone town halls are an increasingly prevalent method for members of Congress (MCs) to communicate with constituents, even while garnering popular criticism for failing to facilitate engagement and accountability. Yet scholars have paid little attention to the events and their effects, and even less to how they might be improved. To remedy this problem, we report on a field experiment in which four MCs joined their constituents in telephone town halls. Overall, participation in an event improved constituents’ evaluations of the format in general, and of the MC in particular. Furthermore, we studied how these events might be improved by evaluating a reform—a single‐topic focus with predistributed briefing materials—designed to enhance deliberative interaction. This reform enhanced effects on opinions of the format without significantly altering effects on attitudes toward the MC. Our results suggest that telephone town halls hold promise for constituents, officeholders, and democratic practice.     

Hierarchical,Three‐Dimensional Measurement System for Crime Scene Scanning

We present a new generation of three‐dimensional (3D) measuring systems, developed for the process of crime scene documentation. This measuring system facilitates the preparation of more insightful, complete, and objective documentation for crime scenes. Our system reflects the actual requirements for hierarchical documentation, and it consists of three independent 3D scanners: a laser scanner for overall measurements, a situational structured light scanner for more minute measurements, and a detailed structured light scanner for the most detailed parts of tscene. Each scanner has its own spatial resolution, of 2.0, 0.3, and 0.05 mm, respectively. The results of interviews we have conducted with technicians indicate that our developed 3D measuring system has significant potential to become a useful tool for forensic technicians. To ensure the maximum compatibility of our measuring system with the standards that regulate the documentation process, we have also performed a metrological validation and designated the maximum permissible length measurement error E_MPE for each structured light scanner. In this study, we present additional results regarding documentation processes conducted during crime scene inspections and a training session.     

20723例亲子鉴定中19个STR基因座的突变分析

目的观察并分析肯定亲权关系的案件,探索STR基因座的突变规律。方法采用Goldeneye 20A试剂盒对20723例肯定亲权关系的案件筛选等位基因突变事件,统计各基因座的突变率和突变等位基因的来源、片段大小、突变步数及重复单位的增加或减少情况,分析突变相关因素的特点。结果 19个STR基因座共发现548例突变,观察到557个突变事件,基因座的突变率为0.07‰~2.23‰。父系突变与母系突变的比例为3.06∶1。突变以一步突变为主,增加与减少重复单位的情况相当;二步以上(含二步)突变更易出现重复单位减少。突变主要发生于中等位基因,重复单位增减比例相当,长等位基因突变中重复单位减少显著多于增加。父系突变出现重复单位增加与减少的比例相当,母系突变重复单位减少较增加多见。结论各基因座的突变率差异具有统计学意义,当出现1~2个基因座不符合遗传规律时,应当加测其他检测系统,并结合突变基因座的信息计算PI值,以进一步明确鉴定意见。     

Predictors of Initial Court Agreement and 1‐Year Relitigation in Title IV‐D Contested Paternity Cases

We examined potential predictors of initial court agreement and 1‐year relitigation in a sample of contested paternity cases involving unmarried parents coming to court to establish paternity, child support, and other issues. Cases participated in an RCT of a parent program and of a waiting period between establishment of paternity and court hearing. We controlled for RCT study factors and used baseline assessment data to predict likelihood of reaching full agreement in the initial court hearing and relitigation in the following year. Findings suggest that cases in which parents get along better outside of court are more likely to reach agreement and less likely to return to court. Additionally, particular parent demographics predict lower likelihood of reaching initial agreement (e.g., parents are non‐White, father earns below $10,000 yearly), more relitigation (e.g., parents are non‐White, mother earns above $10,000 yearly, father has children with others), and less relitigation (e.g., father earns above $10,000 yearly). Child demographics and most parent relationship characteristics did not predict outcomes. We discuss findings and offer suggestions for court interventions.     

美国《1998年国际宗教自由法》及对中美关系的影响评析

<1998年国际宗教自由法>(以下简称IRFA)是由美国保守派推动制订的一部具有域外效力的美国国内法.由于该法所包含的双重标准以及该法在推行过程中必然会产生的诸多问题,该法实施以来"产生"的域外效力十分有限,未对中美关系造成直接影响.但在美国社会不断保守化的背景下,IRFA对中美关系的间接和负面影响不容小视.针对美国国务院每年发布的<国际宗教自由年度报告>中对中国宗教自由状况的歪曲,中国政府予以外交上的坚决谴责是必须的,但从根本上说,在宗教领域奉行接触政策,勿视美国为敌,怀柔美国应是当前我国韬光养晦外交的较佳选择.     

美国对俄罗斯投资的发展现状及特点分析

俄罗斯与美国作为世界的两个大国 ,双方的经济合作关系及其发展状况备受世人关注。特别是 90年代以来 ,俄美出于各自的需要 ,积极努力推动双方在投资领域的合作 ,取得了一定成效。从目前走势来看 ,美国经济将步入增长性衰退期 ,投资收益率的下降使得美国资本向外转移的可能性增大 ,这为俄美在经贸、投资等领域的进一步合作提供了契机     

美日同盟的出现与冲绳问题的产生

近数年来,围绕着驻冲绳美军基地,特别是普天间基地问题,美国、日本中央政府、冲绳地方政府两国三方之间发生了尖锐的冲突和争执。冲绳的民众为支持地方政府的政策再次掀起要求美军基地撤离的大规模群众运动。战后以来冲绳人一直在抗争试图减少基地甚至是实现无基地化,60多年过去了,冲绳仍然生活在基地当中。那么,冲绳问题在战后之初到底是如何形成的呢?从美日同盟的角度来探讨这个问题,可以看出,美日同盟的出现导致了冲绳问题的产生。《旧金山对日和约》结束了日本被占领状态,同时《美日安全条约》的签订确定了美日安保体制的法律框架,对冲绳来说更为重要的是《旧金山对日和约》第三条也成为美国统治冲绳的法律依据。也就是说,《旧金山和约》和《美日安全条约》结束了美日之间的敌对关系,并开启了两国之间的同盟关系,与此同时,美日安保体制的确立也就意味着冲绳问题的出现。     

近期美国升高西太平洋紧张局势的战略意图及其影响

随着美国全球战略重心加速东移,特别是在近期美国从伊拉克撤军与从阿富汗准备抽身而退之时,美国在亚太地区频频举行军事演习,尤其是美借天安舰之机,趁势强化美韩与美日同盟,并高调介入南海争端,与东南亚伙伴强化军事互动,积极谋求南海争端的国际化。美国正沿太平洋,从东北亚至东南亚一线,事实上形成了针对中国的战略围堵。美国近期升高西太平洋紧张局势的一系列举动并不是偶然的,而是冷战后美国全球战略重心从大西洋向太平洋转移的重要组成部分。奥巴马加速重返亚太的战略调整将对中国实施远海战略与拓展战略纵深以及推行和谐周边的外交战略产生冲击。
