美国干预联合国事务的行为根源--从美参议员要求安南辞职谈起

美国作为联合国常任理事国对联合国的形成和发展做出过突出贡献.同时,美国对联合国事务的干预也达到了绝大多数成员国难以容忍的程度.本文认为,美国对联合国事务的干预,甚至搞单边主义,原因是多方面的.既有历史的,也有现实的;既有客观的,也有主观的,是综合因素的结果.联合国改革和国际关系的民主化、多元化,终将遏制美国的霸权主义和单边主义.     

China and the Middle East

The exchanges between China and the Middle East are profound. In 500 B. C, the world-famous Silk Road was built. In 700 B. C, there were two great empires on the Asian Continent.

Portable high‐resolution automated 3D imaging for footwear and tire impression capture

The forensic science community raised the need for improved evidence recognition, collection, and visualization analytical instrumentation for field and laboratory use. While the 3D optical techniques for imaging static objects have been extensively studied, there is still a major gap between current knowledge and collecting high‐quality footwear and tire impression evidence. Among optical means for 3D imaging, digital fringe projection (DFP) techniques reconstruct 3D shape from phase information, achieving camera‐pixel spatial resolution. This paper presents a high‐resolution 3D imaging technology using DFP techniques dedicated to footwear and tire impression capture. We developed fully automated software algorithms and a graphical user interface (GUI) that allow anyone without training to operate for high‐quality 3D data capture. We performed accuracy evaluations and comparisons comparing with the commercial high‐end 3D scanner and carried out qualitative tests for various impressions comparing with the current practices. Overall, our technology achieves similar levels of accuracy and resolution with a high‐end commercially available 3D scanner, while having the merits of being (1) more affordable; (2) much easier to operate; and (3) more robust. Compared with the current practice of casting, our technology demonstrates its superiority because it (1) is non‐destructive; (2) collects more evidence detail than casts, especially when an impression is fragile; (3) requires less time and money to collect each piece of evidence; and (4) results in a digital file that can easily be shared with other examiners.     

Combined Collection and Analysis of Inorganic and Organic Gunshot Residues

Gunshot residue (GSR) analysis and their interpretation provide crucial information on a criminal investigation involving the use of firearms. To date, several approaches have been proposed for the implementation of a combined sampling and analysis of inorganic (IGSR) and organic GSR (OGSR). However, it is not clear at this stage if concurrent analyses of both types of residue might be detrimental to the analysis of IGSR currently applied in forensic laboratories. Thus, this work aims to compare and evaluate three different protocols for the combined collection and analysis of IGSR and OGSR. These methods, respectively, involve the use of a modified stub (with two halves, one for the detection of IGSR and the other for the analysis of OGSR); the sequential recovery of GSR with two stubs mounted with different adhesives (double-sided carbon tape and Tesa® TACK) and the sequential analysis of IGSR and OGSR from a single carbon stub following carbon deposition. The detection of IGSR was carried out using SEM-EDX, while OGSR analysis was performed using ultra-high-performance liquid chromatography–tandem mass spectrometry (UHPLC-MS/MS). Obtained results for experiments performed using Geco Sinoxid^® ammunition indicated that sequential analysis was the most suitable protocol for the combined collection and analysis of both IGSR and OGSR. A higher number of inorganic (characteristic and consistent) particles and higher concentrations of ethylcentralite, N-nitrosodiphenylamine, diphenylamine, and nitroglycerin were recovered with this method.     

Do Political Similarities Facilitate Interlocal Collaboration?

This research examines the extent to which political similarities—that is, homophily between political actors at the local level—affect patterns of interorganizational collaboration in an emergency response situation. While the field of emergency management has focused on implementation‐oriented arrangements among key stakeholders, few studies have systemically investigated the creation and development of interorganizational collaborations led by political actors, especially following catastrophic events. The analysis reveals that a dyadic tie with political homophily boosts local responders’ ties with other agencies during emergencies. Findings indicate that political solidarity, formulated by chief elected officials of municipalities and council members, can broaden the scope of interorganizational collaboration by mitigating institutional collective action problems at the local level. This research presents a critical recommendation for emergency managers that interlocal collaboration for timely response to a disaster is attributable to political similarities that facilitate frequent interlocal interactions through formal and/or informal agreements.

中国青少年犯罪演进的定量分析

上世纪90年代以来，青少年罪犯数量大幅度下降，近几年开始有所缓慢回升，青少年罪犯占全国罪犯总体的比例呈下降趋势，然而，青少年人口犯罪率居高不下，并呈上升趋势。由此我们看到反映青少年犯罪情况的两个代表性指标一一犯罪数量和人口犯罪率。影响青少年犯罪数量变化的主要因素是人口基数和青少年人口犯罪率，而后者更能够反映青少年个体及群体的越轨行为危险程度。我们在青少年犯罪预防决策和实务工作中更应当密切关注青少年人口犯罪率，同时重视青少年群体人口基数的变化。此外，从罪犯数量和人口犯罪率两个指标来看，未成年人与青年两个亚群体差异较为明显，因此青少年犯罪预防工作不能笼而统之，需要日益精细化、专业化。
