Positions and saliency of immigration in party manifestos: A novel dataset using crowd coding

Immigration is one of the most widely debated issues today. It has, therefore, also become an important issue in party competition, and radical right parties are trying to exploit the issue. This opens up many pressing questions for researchers. To answer these questions, data on the self‐ascribed and unified party positions on immigration and immigrant integration issues is needed. So far, researchers have relied on expert survey data, media analysis data and ‘proxy’ categories from the Manifesto Project Dataset. However, the former two only give the mediated party position, and the latter relies on proxies that do not specifically measure immigration. The new dataset presented in this article provides researchers with party positions and saliency estimates on two issue dimensions – immigration and immigrant integration – in 14 countries and 43 elections. Deriving the data from manifestos enables the provision of parties’ unified and unfiltered immigration positions for countries and time points not covered in expert surveys and media studies, making it possible to link immigration and immigrant integration positions and saliency scores to other issue areas covered in the Manifesto Project Dataset. Well‐established criteria are used to distinguish between statements on (1) immigration control and (2) immigrant integration. This allows for a more fine‐grained analysis along these two dimensions. Furthermore, the dataset has been generated using the new method of crowd coding, which allows a relatively fast manual coding of political texts. Some of the advantages of crowd coding are that it is easily replicated and expanded, and, as such, presents the research community with the opportunity to amend and expand upon this coding scheme.     

改革开放 40 年来中国企业员工集体离职机制的 典型案例研究

企业员工集体离职对相关组织和员工群体影响深远。本研究从 1978—2021 年中国知网（CNKI） 4 类论文数据库及报纸 1 类新闻数据库中，甄选出我国 102 个企业员工集体离职典型案例。研究发现：集体离 职集中发生在时代的热门行业、朝阳产业，其中制造业、IT 业的集体离职始终处于焦点；集体离职的主要原 因是个体自身因素、企业内部因素以及二者互动因素；集体离职的直接原因同样主要在内因，成为集体离职的 “导火索”或“催化剂”。研究提炼出企业员工集体离职影响因素和作用机制模型、企业员工集体离职主要原 因和直接原因作用模型。基于此，研究建议：预防集体离职需整体上更加关注企业的内部管理，化解集体离职 需避免主要原因的积累，缓解集体离职还需注意直接原因的作用。     

法医线粒体DNA检测的系统效能及应用价值

线粒体DNA（mitochondrial DNA，mtDNA）遗传标记的检测在法医学实践中有着重要的价值。线粒体DNA异质性的出现，对检测体系的系统效能存在着影响，主要表现在对所检测样本的单倍型的认同及个体识别概率的计算上。通过建立mtDNA数据库，找出异质性在人群中的发生频率，并使检测异质性的方法标准化．对线粒体DNA的更有效检测具有重要意义；线粒体DNA编码区多态性位点在提高线粒体DNA系统效能中具有独到之处。因此，更进一步地进行mtDNA编码区多态性的探索．将进一步提高线粒体DNA检测的系统效能。     

计算机网络犯罪规制中的“未经授权”与“超越授权”——中美比较研究

件和基础是行为人未经授权或超越授权访问计算机网络。中美两国在规制计算机网络犯罪的访问行为上都有关于“未经授权”和“超越授权”的规定,对比两国立法和司法条文以及法院判解,我国规定的“未经授权”和“超越授权”只是概念式存在,司法解释没有予以定义,司法实践也未形成明确认定标准。科学借鉴美国立法和司法经验,结合中国实际完善我国规定的“未经授权”与“超越授权”:以程序编码设限作为判断计算机访问未经授权的标准;“超越授权”是指行为人在获得授权使用计算机时,利用这一授权使用的机会去获取计算机信息系统中的数据或控制计算机信息系统,但行为人的数据获取或控制行为并没有得到授权。     

A New Tool for Coding and Interpreting Injuries in Fatal Airplane Crashes: The Crash Injury Pattern Assessment Tool Application to the Air France Flight AF447 Disaster (Rio de Janeiro–Paris), 1st of June 2009

For investigation of air disasters, crash reconstruction is obtained using data from flight recorders, physical evidence from the site, and injuries patterns of the victims. This article describes a new software, Crash Injury Pattern Assessment Tool (CIPAT), to code and analyze injuries. The coding system was derived from the Abbreviated Injury Score (AIS). Scores were created corresponding to the amount of energy required causing the trauma (ER), and the software was developed to compute summary variables related to the position (assigned seat) of victims. A dataset was built from the postmortem examination of 154/228 victims of the Air France disaster (June 2009), recovered from the Atlantic Ocean after a complex and difficult task at a depth of 12790 ft. The use of CIPAT allowed to precise cause and circumstances of deaths and confirmed major dynamics parameters of the crash event established by the French Civil Aviation Safety Investigation Authority.

The Use of Mitochondrial DNA Single Nucleotide Polymorphisms to Assist in the Resolution of Three Challenging Forensic Cases

Abstract:  Mitochondrial DNA (mtDNA) single nucleotide polymorphisms (SNPs) in an 11-plex assay were typed in three missing person cases involving highly degraded human remains. Unlike the traditional forensic approach to analyzing mtDNA which focuses on sequencing portions of the noncoding Control Region, this assay targets discriminatory SNPs that reside principally in the coding region. In two of the cases, the SNP typing successfully excluded one of two reference families that could not be excluded on the basis of mtDNA hypervariable region sequencing alone, and resulted in the final resolution of both decades-old cases. In a third case, SNP typing confirmed the sorting and reassociation of multiple commingled skeletal elements. The application of a specific mtDNA SNP assay in these cases demonstrates its utility in distinguishing samples when the most common Caucasian hypervariable region type is encountered in forensic casework.     

Can computed tomography replace or supplement autopsy?

Postmortem computed tomography (PMCT) has been integrated into the practice of many forensic pathologists. To evaluate the utility of PMCT in supplementing and/or supplanting medicolegal autopsy, we conducted a prospective double-blind comparison of abnormal findings reported by the autopsy pathologist with those reported by a radiologist reviewing the PMCT. We reviewed 890 cases: 167 with blunt force injury (BFI), 63 with pediatric trauma (under 5 years), 203 firearm injuries, and 457 drug poisoning deaths. Autopsy and radiology reports were coded using the Abbreviated Injury Scale and abnormal findings and cause of death (COD) were compared for congruence in consensus conferences with novel pathologists and radiologists. Overall sensitivity for recognizing abnormal findings was 71% for PMCT and 74.6% for autopsy. Sensitivities for PMCT/autopsy were 74%/73.1% for BFI, 61.5%/71.4% for pediatric trauma, 84.9%/83.7% for firearm injuries, and 56.5%/66.4% for drug poisoning deaths. COD assigned by reviewing PMCT/autopsy was correct in 88%/95.8% of BFI cases, 99%/99.5% of firearm fatalities, 82.5%/98.5% of pediatric trauma deaths, and 84%/100% of drug poisoning deaths of individuals younger than 50. Both autopsy and PMCT were imperfect in recognizing injuries. However, both methods identified the most important findings and are sufficient to establish COD in cases of BFI, pediatric trauma, firearm injuries and drug poisoning in individuals younger than 50. Ideally, all forensic pathologists would have access to a CT scanner and a consulting radiologist. This would allow a flexible approach that meets the diagnostic needs of each case and best serves decedents' families and other stakeholders.     

Assessing the ‘Gold Standard’ of party policy placements: Is computerized replication possible?

The Comparative Manifestos Project (CMP) offers data on party policy positions based on a coding scheme of 56 categories. To what extent can we replicate the CMP coding results by using computerized topical coding of digitalised manifestos? Both human and computer coding have a number of strengths and weaknesses so that the combination of strengths could help to arrive at both valid and reliable party policy placements, in particular the measurement of policy movements over time. More than 1500 digitalised party manifestos in 20 democracies in the period 1960–2009 are re-coded with a computerized CMP-compatible coding scheme in order to assess the differences with human coding using exactly the same issue categories and the same left–right scale.The analysis shows that it is possible to use computer coding in order to locate the potential weakness of the human coding and the other way around. It also illustrates that the validity and reliability of policy placements is a function of the conceptualisation and operationalisation of issues, of the size of documents and of scale construction. Computerized cross-validation of the CMP-coding results offers a new and powerful tool to assess its reliability.
