Spherical Photography and Virtual Tours for Presenting Crime Scenes and Forensic Evidence in New Zealand Courtrooms

The delivery of forensic science evidence in a clear and understandable manner is an important aspect of a forensic scientist's role during expert witness delivery in a courtroom trial. This article describes an Integrated Evidence Platform (IEP) system based on spherical photography which allows the audience to view the crime scene via a virtual tour and view the forensic scientist's evidence and results in context. Equipment and software programmes used in the creation of the IEP include a Nikon DSLR camera, a Seitz Roundshot VR Drive, PTGui Pro, and Tourweaver Professional Edition. The IEP enables a clear visualization of the crime scene, with embedded information such as photographs of items of interest, complex forensic evidence, the results of laboratory analyses, and scientific opinion evidence presented in context. The IEP has resulted in significant improvements to the pretrial disclosure of forensic results, enhanced the delivery of evidence in court, and improved the jury's understanding of the spatial relationship between results.     

东亚海上安全合作中的国际法问题——兼论国家实践中紧追要件的变化

导致海上执法领域沿海国和他国之间的管辖权发生冲突的原因复杂多样,其结果都导致周边国家间的关系对立、影响地区安全、削弱国际海洋法律秩序的统一性和权威性。构建东亚地区海上安全合作机制应在各国普遍接受的国际法框架内进行。为此目的,相关国家需摈弃一味追求本国利益而对国际公约做任意扩大解释,以避免加剧国际法的分裂。

How Much Time Should the Police Spend at Crime Hot Spots? Answers from a Police Agency Directed Randomized Field Trial in Sacramento,California

Hot spots policing has been shown to be an effective strategy for reducing crime across a number of rigorous evaluations, but despite this strong body of research, there still exist gaps in our knowledge of how officers can best respond to hot spots. We report on a randomized experiment in Sacramento, California that begins to address these gaps by testing the recommendation from prior research that police officers randomly rotate between hot spots, spending about 15?min patrolling in each. Our results suggest significant overall declines in both calls for service and crime incidents in the treatment hot spots relative to the controls. Additionally, the study was carried out primarily by the Sacramento Police Department without any outside funding. In an era of limited economic resources for policing, this experiment suggests a model by which police agencies can take ownership of science and oversee the implementation and evaluation of evidence-based interventions.     

网络热词—民意之窗

网络热词本身蕴含着丰富的社会文化心理因素,它的流行不仅仅是一种语言现象,其背后往往是一个新闻事件或一类社会现象,带有社会发展进程中深深的烙印。每一个网络热词的诞生和迅速流传,反映的都是社会生活和民意民情。分析网络热词反映民意的表现、流行特点及流行原因,可以客观揭示网络热词与公众情绪间的关系。     

Hot spots policing and crime prevention: A systematic review of randomized controlled trials

Crime scholars and practitioners have argued that police actions should be focused on high-risk crime places rather than spread thinly across the urban landscape. This review examines five randomized controlled trials of the effects of concentrating police enforcement efforts on crime hot spots. The findings of these evaluations suggest that focused police actions can prevent crime and disorder in crime hot spots. A meta-analysis of the effect sizes from the five experiments reveals a statistically significant mean effect size for hot spots policing interventions; this suggests overall reductions in citizen calls for service in the treatment hot spots relative to the control hot spots. These studies also suggest that focused police actions at specific locations do not necessarily result in crime displacement. Although these evaluations reveal that these programs work in preventing crime, additional research is needed to unravel other important policy-relevant issues such as community reaction to focused police enforcement efforts.

热连轧带钢生产过程中的温度场模拟

温度是热连轧带钢生产中影响产品的组织和性能重要参数,采用ANSYS有限元对热连轧生产过程的温度场进行数值模拟。模拟结果表明:高压水除鳞对带钢温度场影响相当大,高压水除鳞后,带钢端部和表面温度显著下降,带钢中心的温度基本保持不变,表面和芯部温度梯度大,除鳞后在轧件内部热传导作用下,温度梯度越来越小,最后整个轧件除端部外温度趋于均匀。
