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.     

SNOWBOARD WUNDERKIND

Child actor-turned snowboarder Su Yiming blazes China’s path to snow sports success At Genting Snow Park in Zhangjiakou, Hebei Province, Chinese teenage snowboarder Su Yiming put down three stunning runs to win silver in the men’s snowboard slopestyle on February 7. It was the first time a Chinese athlete had competed in this event at any Olympics.     

Estimating Individual Contributions to Complex DNA SNP Mixtures.,

High‐throughput sequencing (HTS) of large panels of single nucleotide polymorphisms (SNPs) provides an alternative or complimentary approach to short tandem repeats (STRs) panels for the analysis of complex DNA mixture forensic samples. For STRs, methods to estimate individual contribution concentrations compare capillary electrophoresis peak heights, peak areas, or HTS allele read counts within a mixture. This article introduces three approaches (mean, median, and slope methods) for estimating individual DNA contributions to forensic mixtures for HTS/massively parallel sequencing (MPS) SNP panels. For SNPs, the major:minor allele ratios or counts, unique to each contributor, were compared to estimate contributor proportion within the mixture using the mean, median, and slope intercept for these alleles. The estimates for these three methods were typically within 5% of planned experimental contributions for defined mixtures.

Public and elite opinion on international human rights law: Completing the causal chain of the domestic compliance mechanism

Why do states comply with international human rights law? Scholars have looked to domestic politics to suggest a constituency-driven domestic compliance mechanism. However, it is unclear if strong public support for compliance leads to greater willingness to comply among elected officials. This study is the first to empirically demonstrate the complete causal chain of a constituency-driven domestic compliance mechanism. Using a survey experiment, this study first finds that a strong state commitment to UN Norms on the Responsibilities of Transnational Corporations (RTNC) increases public support for compliance. Using a parallel lab-in-the-field experiment of sitting legislators, the study then finds that a strong state commitment to RTNC is similarly associated with increased elite support for compliance. Finally, the study finds that public demand for compliance is associated with even greater elite support for compliance. Public demand for compliance seems to elicit elite willingness to comply by raising reputational concerns.     

政府与社会组织关系演进的历史逻辑

从总体性二元合一走向分化性二元合一,解决分化与耦合两个方面的问题,是中国政府与社会组织关系演进的总体态势。运用结构功能主义视角,可以发现,演进历经让渡与承接、规范与依附、激活与协同等阶段,由政府与社会组织的功能性界分,到基于责任结构整合的政会功能黏附,逐渐发展为基于全面结构整合的政会功能分化与耦合。演进的基本逻辑,是政府主导下功能演变与结构调整的互动,即由政府主导的演进轨道、由功能演变与结构调整互动而构成的演进机制。展望未来,分化性二元合一体系的完善,必须按照现代国家治理的要求,在政府与社会组织之间打造共建、共治与共享的结构功能系统,实现基于责任结构契合的功能目标一致、基于权力结构合理的功能形式耦合、基于利益结构规范的功能输出互益。
