Relatively Permanent Pigmented or Vascular Skin Marks for Identification: A Pilot Reliability Study

In child sexual exploitation offenses, the collected evidence images often show the skin of nonfacial body parts of the criminals and victims. For identification in this scenario, “relatively permanent pigmented or vascular skin marks,” abbreviated as RPPVSM, were recently introduced as the basis for a novel biometric trait. This pilot study evaluated the interexaminer variability of RPPVSM identification. Four dermatology physicians were recruited to examine RPPVSM from 75 skin images collected from a total of 51 Caucasian and Asian subjects. The images were separated into 50 reference (“suspect”) images and 25 evaluation (“evidence”) images. The examiners were asked to perform identification by annotating RPPVSM in each of the 25 evaluation images and matching them with the reference images. The rate of misidentification was 0% while the mean rate at which examiners failed to find a match was 6%, indicating the potential of dermatology physicians performing the role of RPPVSM examiners.     

Decoding hidden darknet networks: What we learned about the illicit fentanyl trade on AlphaBay

The opioid epidemic, impacted from the proliferation of fentanyl, has added impetus to the need to detect fentanyl, sources of fentanyl, and places where fentanyl and drugs adulterated with fentanyl are available. Many darknet marketplaces (DNMs) have rules that ban fentanyl. However, it is unclear how these affect the fentanyl market. Using the AlphaBay DNM as a case study, we conducted mixed methods qualitative research. We scraped and analyzed data from the AlphaBay I2P website using, among other methods, content and social network analysis, to uncover hidden fentanyl networks. Our research highlights the next evolution of darknet marketplaces – the migration of DNMs from Tor to I2P and the methods that can be used identify fentanyl networks, irrespective of where sites are: I2P, Tor, or multihomed on I2P and Tor. Despite its ban in the Global AlphaBay Rules, our research revealed the sale of fentanyl on the AlphaBay DNM. Unlike previous studies, our findings predominantly revealed the covert sale of fentanyl on AlphaBay and predatory vendors selling illicit drugs, which unbeknownst to buyers, contained fentanyl. To a lesser extent, our findings identified the overt sale of fentanyl patches on AlphaBay. Although we examined only one DNM, the prevalence of the covert sale of fentanyl and the presence of predatory vendors underscores the importance of research that decodes the language of vendors who surreptitiously sell fentanyl or drugs adulterated with fentanyl or other illicit substances. The results of our research can inform strategies aimed at disrupting and dismantling DNM fentanyl networks.     

当代知识产权制度发展的形势和特点

知识产权已成为一个全球性问题和世界热点问题。当代知识产权制度发展的形势和特点主要表现在以下几方面:知识产权与贸易直接相关并成为贸易本身的标的、知识产权成为发达国家跨国公司垄断技术和市场的重要手段、知识产权与国际政治经济紧密相连并出现全球保护主义和独占主义思想、发展中国家和发达国家在知识产权保护方面存在激烈冲突、知识产权国际化趋势进一步增强。     

技术法规的基本观念反思

我国学者有关技术法规的基本观念多有争议和误解。其实,作为名称,技术法规并非源自对WTO/TBT协定中"Technical regulations"的翻译,而是早在加入WTO之前就已在我国使用。作为概念,它在不同情况下有不同的含义。作为事物,它像法一样是融有关国际与国内,实体与程序,行政、民事与刑事诸法规范于一体的关于技术问题的法律规范体系,在定位上具有复杂性、综合性。而且,在不同情况下它与强制性标准之间在逻辑上至少可能存在种属、等同、整分三种关系。     

上海自由贸易试验区对我国涉外经济法制转型的影响

上海自贸区正式获准成立,这是中国法治转型中的重大创新。上海自贸区内通过临时性的授权调整,逐步推进行政审批体制改革,实行准入前国民待遇和"负面清单"管理模式,以此推进政府职能转变;在投资领域努力扩大服务业的投资开放、促进外商投资准入制的转轨、构筑对外投资服务促进法律体系;在贸易领域积极推动贸易结构的转型升级、提升国际航运服务能级;在金融领域应加快金融制度创新,增强金融服务能力,实现"在岸金融"与"离岸金融"的互动;并在争议解决机制构建方面也进行了卓有成效的探索。     

我国绿色贸易壁垒法律制度的性能评价体系研究

随着世界进入"环保时代",绿色贸易壁垒法律制度对一国的经济贸易的影响越来越突出和重要,面对我国绿色贸易壁垒法律制度立法、执法、司法绩效不容乐观的情况,以新制度经济学的制度绩效为主要的理论基础,设立我国绿色贸易壁垒法律制度的性能评价体系,能够为我国绿色贸易壁垒法律的制度设计和实践操作开创定量评判的崭新标准。     

扫描电镜/X射线能谱仪检验电流斑规范化方法探讨

目的探讨电流斑皮肤金属化的机理、检材提取处理和扫描电镜/能谱仪检验规范化方法,对检验结果进行分析和价值判断。方法用扫描电镜/能谱检验,采用低倍大窗口覆盖损伤区域采集平均元素能谱图,并在可能的金属元素富集区域寻找球形金属颗粒。结果扫描电镜下可观察到散在的孔穴、细胞碎屑、龟裂、裂隙等特征,有些电流斑可检出金属元素,其中部分电流斑可发现球形金属颗粒。结论采用规范化的检材提取、处理和检验方法可消除随意性方法造成错检的可能。电流斑皮肤上异常含量的金属附着可支持病理检验符合电流斑表现的结论,同时也为电击导体的推断和金属元素成分比对提供依据。球形金属颗粒的发现揭示存在电弧高温的可能性极大,可强力支持病理检验符合电流斑表现的结论。     

亚太经合组织中区域利益和成员利益的冲突与协调——APEC成立十周年回顾与展望

亚太经合组织（ＡＰＥＣ） 是区域利益的代表。作为成员利益的集中体现,ＡＰＥＣ 的区域利益主要由贸易投资自由化和经济技术合作两大部分组成。由于发达成员和发展中成员在以上两个方面有不同的利益追求,ＡＰＥＣ 中区域利益和成员利益一直存在着冲突。在过去的十年中,贸易投资自由化和经济技术合作的不平衡发展使这种冲突逐渐表面化。展望未来,ＡＰＥＣ 的持续发展有赖于成员经济体享有充分灵活性的基础上,通过协商一致,处理好发达成员和发展中成员的利益分歧     

Meeting the challenges of the handicraft industry in Africa: Evidence from Nairobi

This article presents findings on observed productivity constraints of handicraft firms in Nairobi, Kenya. The goal is to help NGOs, intergovernmental organisations, and national governments in their efforts to foster local handicraft industries in Africa and beyond. One-hundred and two respondents were interviewed about their business, cost structure, hiring practices, and other intra-industry relationships. This article points out a number of practical problems hindering productivity and limiting livelihoods, including problematic labour practices, conditions of adverse selection, the context of proprietary information in small scale manufacturing, and the tendency of the industry toward hypercompetition.     

The Demand for Protectionism: Democracy,Import Elasticity,and Trade Barriers

Numerous studies suggest that democracies employ lower trade barriers than nondemocracies. In this article, we examine the conditioning role that the elasticity of import demand at the commodity level plays on the relationship between democracy and import barriers. Beginning with the assumption that democracies are more responsive than nondemocracies to the preferences of mass publics, we demonstrate that the value of free trade as a public good depends on the elasticity of import demand. When import demand for a given commodity is inelastic, trade barriers are more harmful to consumers; as such, democracies will employ lower trade barriers than nondemocracies. However, as import demand becomes more elastic, publics find it easier to adjust to higher prices; as a result, the difference in imposed trade barriers by regime type decreases. We find support for this argument in statistical analyses of crosssectional data covering 4,656 commodities imported by 73 countries Furthermore, we find that democracies raise higher trade barriers than nondemocracies on commodities for which import demand is very elastic.
