iCLIC Data Mining and Data Sharing workshop: The present and future of data mining and data sharing in the EU

Held at Southampton University's Highfield campus and hosted by iCLIC, an interdisciplinary core on Law, the Internet and Culture, the Data Mining and Data Sharing workshop brought together attendees and speakers from industry, government, academia and a range of disciplines alike. The workshop comprised two sessions, each with a keynote and an associated panel. The first session was chaired by Eleonora Rosati and dealt with copyright and database rights, data mining and data sharing. The second session, chaired by Sophie Stalla-Bourdillon, focussed on data protection, data mining and data sharing. The following report covers both sessions, associated panel discussions and the subsequent question and answer sessions.     

酮洛芬注射液在乳牛体内的残留消除研究

为建立牛乳中酮洛芬的液相色谱-串联质谱(LC-MS/MS)检测方法,牛乳样品经甲醇提取,C18色谱柱分离,采用正离子模式,多反应监测,内标法定量。结果表明,牛乳中酮洛芬的检出限为1μg/kg,定量限为5μg/kg,在5~200μg/kg范围内线性关系良好,相关系数大于0.99。在25~100μg/kg添加水平的回收率为93.3%~107.5%,批内、批间相对标准偏差分别为1.72%~5.46%、1.13%~7.04%。该方法高效、灵敏、准确,可作为牛乳中酮洛芬的检测方法。选用20头健康的泌乳期荷斯坦乳牛,高产、低产各10头,以3 mg/kg剂量肌内注射给药,每天1次,连用3 d,分别于每次给药后第2、15小时采集乳样。每次给药后2 h牛乳中可检出酮洛芬,最高质量分数为(38.43±3.90)μg/kg,停药后15 h均未检出。所有时间点牛乳中酮洛芬质量分数的实测结果均低于加拿大规定的最高残留限量50μg/kg,建议弃乳期为0 d。     

Metrological framework for selecting morphological characters to identify species and estimate developmental maturity of forensically significant insect specimens

Accurate age estimates of immature necrophagous insects associated with a human or animal body can provide evidence of how long the body has been dead. These estimates are based on species-specific details of the insects’ aging processes, and therefore require accurate species identification and developmental stage estimation. Many professionals who produce or use identified organisms as forensic evidence have little training in taxonomy or metrology, and appreciate the availability of formalized principles and standards for biological identification. Taxonomic identifications are usually most readily and economically made using categorical and qualitative morphological characters, but it may be necessary to use less convenient and potentially more ambiguous characters that are continuous and quantitative if two candidate species are closely related, or if identifying developmental stages within a species. Characters should be selected by criteria such as taxonomic specificity and metrological repeatability and relative error. We propose such a hierarchical framework, critique various measurements of immature insects, and suggest some standard approaches to determine the reliability of organismal identifications and measurements in estimating postmortem intervals. Relevant criteria for good characters include high repeatability (including low scope for ambiguity or parallax effects), pronounced discreteness, and small relative error in measurements. These same principles apply to individuation of unique objects in general.

Key points

• Metrological rigour can increase in forensic entomology by selecting measurements based on their metrological qualities.
• Selection of high-quality features for morphological identification of organisms should consider these criteria: (1) pronounced discreteness of features (minimising group overlap or maximizing interval); (2) high repeatability of assessment (such as symmetrical width rather than asymmetrical length); (3) small relative error in measurement (selecting the physically largest continuous rigid feature for measurement).
• These metrological principles also apply to individuation of unique objects in general.

Postmortem chest computed tomography for the diagnosis of drowning:a feasibility study

It may be difficult to distinguish the cause of death in drowning cases without specific findings. The aim of this study was to explore the forensic value of thoracic postmortem computed tomography (PMCT) using routine images and three-dimensional (3D) image reconstructions. The imaging data of PMCT examinations of six drowning cadavers, aged 21–54 years, were analyzed. Twelve victims of sudden death from coronary artery disease (CAD) were chosen as a control group. After 3D bilateral lung images were reconstructed using image processing software, an interactive medical image control system was used to measure and analyze parameters including lung volume, lung volume ratio, mean CT value of the whole lung, and lung CT value distribution curves. Lung volume and lung volume ratio were used to assess the shape changes of the lung. Lung CT value distribution curves showed the corresponding number of pixels of the different CT values in the lung image. Lung volume was not significantly larger in drowning cases (mean 2 958 cm³) than in controls (mean 2 342 cm³). Lung volume ratio values in the drowning group (mean 0.3156) were greater than those in the control group (mean 0.2763); (P = 0.02). There was no significant difference between the drowning and control group in the mean CT value of the whole lung. There were differences between lung CT value distribution curves in drowning victims and controls, with drowning victims showing a single peak and CAD cases showing a bimodal distribution. Thoracic PMCT is helpful for the forensic medical diagnosis of drowning. Lung volume ratio and lung CT value distribution are potential indicators to distinguish between drowning and CAD.     

Sectoral linkages at the beginning of the 21st century: The role of Polish economy in global production structures

This paper provides a first attempt in analyzing the role of Polish economy in the production structure of the global economy in the early years of the 21st century. For the purpose of this analysis, we propose a new approach in which two most important aspects of interindustry linkages in a global input-output model are examined. Contrary to previous studies focused on output-oriented key sector analyses in post-communist CEE economies, we focus on a fundamental policy target variable – income per gross output. In order to analyze the issues in question in a dynamic framework, the empirical results are based on the 2000 and 2014 global intercountry input-output tables for the 28 EU countries as well as 15 other major countries in the world.     

论网络“人肉搜索”在侦查工作中的运用

网络人肉搜索是在现代信息科技手段的辅助下,人工参与并提纯信息的一种新兴信息获取方式。实践证明,人肉搜索强大的搜索能力有助于侦查部门查明犯罪嫌疑人身份、锁定犯罪嫌疑人位置、扩大破案线索、查明尸源。人肉搜索在侦查中的运用,是网络时代侦查破案的新途径,是侦查工作群众路线的新形式。在侦查工作中,人肉搜索的运用应当作为一种最后手段,在运用的范围、条件和程序上进行严格控制,在运用方法上要科学合理,兴其利而除其弊,合法地为侦查破案服务。

群体性事件临战处置的战术探讨

群体性事件之所以难以处置,不仅在于群体性事件发生的原因杂、涉及广、人数众、局面乱,还在于指导公安机关处置群体性事件的意见和规定或过于抽象,或过于笼统,缺少适应性和操作性,跟不上治安形势的发展。尽管在群体性事件的临战处置中,警察的职责任务、警力调动、处置措施都有相应的规定,但目前从警察临战战术的层面进一步研究群体性事件的处置程序和方法,使之更具有操作性和针对性,仍是公安理论研究的一项迫切任务。     

Measuring subnational democracy: toward improved regime typologies and theories of regime change

Social scientists have been limited in their work by the paucity of global time series data about subnational institutions and practices. Such data could help scholars refine regime typologies, improve theories of democratization and regime change, better understand subnational democracy, and illuminate issues of development, conflict, and governance. This article addresses the lack of data by introducing 22 subnational measures from a new dataset, Varieties of Democracy. Validity tests demonstrate that the measures’ strengths outweigh their weaknesses. The measures excel in covering all subnational levels for most countries, capturing different elements of subnational elections, and including a variety of dimensions of elections and civil liberties. The measures also offer unmatched global and temporal coverage. The article demonstrates how these strengths can provide scholars with the benefits described above.
