The Scharff technique: training military intelligence officers to elicit information from small cells of sources

ABSTRACT

Studies have demonstrated the efficacy of the Scharff technique for gathering human intelligence, but little is known about how this efficacy might vary among different samples of practitioners. In this training study we examined a sample of military officers (n?=?37). Half was trained in the Scharff technique and compared against officers receiving no Scharff training. All officers received the same case file describing two sources holding information about a terrorist attack. University students (n?=?74) took the role of the semi-cooperative sources. Scharff-trained officers adhered to the training as they (1) aimed to establish the ‘knowing-it-all’ illusion, (2) posed claims as a means of eliciting information, and (3) asked fewer explicit questions. The ‘untrained’ officers asked many explicit questions, questioned the reliability of the provided information, pressured the source, and displayed disappointment with the source's contribution. Scharff-trained officers were perceived as less eager to gather information and left their sources with the impression of having provided comparatively less new information, but collected a similar amount of new information as their untrained colleagues. The present paper both replicates and advances previous work in the field, and marks the Scharff technique as a promising technique for gathering human intelligence.     

口蹄疫病毒O型和A型交互反应性单克隆抗体的筛选与鉴定

不同血清型口蹄疫病毒(FMDV)之间不能产生交叉免疫保护,但是血清学的交叉反应确实存在。本研究旨在建立一种筛选型间交互反应性抗体的方法,以期为解析FMDV血清型间保守的抗原结构奠定基础。本方法主要依据单个B细胞抗体技术,首先采用两种不同的荧光染料FluoProbes 647H和Pacific Blue分别标记O型与A型FMDV 146S灭活抗原,然后利用流式细胞分选技术,从免疫牛外周血单个核细胞(PBMCs)中分选出结合两种抗原的特异性B细胞,通过单个B细胞抗体基因测定,获得Ig G抗体重链与轻链可变区编码序列,并将可变区基因插入含有牛IgG抗体恒定区的pcDNA3.4载体中,构建IgG抗体的重链与轻链表达质粒。将重链与轻链表达质粒共转染中国仓鼠卵巢悬浮细胞(CHO-S)进行完整抗体表达。结果显示,通过该方法获得了5株FMDV特异性单克隆抗体,其中4株(H64、R82、I16、R29)经间接免疫荧光(IFA)检测都可特异性识别O和A型FMDV;ELISA结果显示,H64、R82、I16与O、A型抗原均具有较好的亲合力;Western-blot结果显示,I16可特异性结合O、A型FMDV结构蛋白VP2中的线性表位,说明在衣壳蛋白VP2上存在血清型间保守的抗原表位,通过本研究进一步加深了对FMDV抗原结构的认识。     

Rhetorical citizenship: studying the discursive crafting and enactment of citizenship

This article argues for the relevance of a rhetorical approach to the study of citizenship, proposing the concept of rhetorical citizenship as a term for a fourth dimension of citizenship and as a scholarly approach to the topic in addition to the dimensions of status, rights, and identity commonly recognized in the literature. We show how this view aligns with current views of the multidi Citizenship Studies mensionality of citizenship, explain our use of the term rhetoric, and illustrate the usefulness of a rhetorical approach in two examples. In close textual readings both examples – one vernacular, one elite – are shown to discursively craft and enact different notions of citizenship vis-a-vis the European refugee crisis. We conclude that a rhetorical perspective on public civic discourse is useful in virtue of its close attention to discursive creativity as well as to textual properties that may significantly, but often implicitly, affect citizens’ understanding of their own role in the polity, and further because it recognizes deep differences as inevitable while valorizing discourse across them.     

浅论犯罪心理画像在我国刑侦实践中的应用

犯罪心理画像主要是运用精神分析、行为心理学的理论和原理对与犯罪有关的行为进行分析,以提供犯罪行为人最为可能的人格特征、心理特征、行为特征等信息,从而协助侦查机关确定侦查范围的一种技术和方法。近些年来,犯罪心理画像已越来越多的引起侦查学界的关注和兴趣。然而只有正确理解和把握犯罪心理画像的适用条件、研究方法、以及厘清刑事科学技术与其的关系,才能更好的将其应用于侦查实践之中。犯罪心理画像可适用于任何刑事案件,关键在于通过剖析、研究个案中犯罪行为人的心理,积累行为资料,为侦查实践提供理论支持和案例指导。     

警察在干预自杀事件中的作用

自杀是一个严重的社会问题。面对当前日益严峻的自杀问题,警察作为维护国家安全、维护社会治安秩序、保护人民生命财产安全的重要力量,在多数情况下是自杀现场的第一处置人员。因此,正确认识自身在处理自杀事件中的角色,掌握恰当的干预自杀的方法与技巧,对于警察来说是极其重要的。     

秘密侦查性质的多维解读

传统上我国学术界普遍从手段或措施的角度对秘密侦查予以认识。这种认识缺陷导致人们对秘密侦查“神秘化”,秘密侦查法治化状况极差。从诉讼法理上而言,秘密侦查的性质应为一种侦查行为和诉讼行为,它具有自身的特征,与强制侦查行为和技术侦查行为有一定的区别。

MVR-PCR及其法医学的应用

小卫星可变重复单位作图(MinisatelliteVariantRepeatmapping,MVRmapping)是近十年发展起来的一项DNA分析技术。本综述对该技术的分子学基础、发展过程及其在法医学的应用作了系统的阐述。认为该技术在个人识别与亲子鉴定方面发挥着为其它DNA分析技术所不可替代的作用,正在成为法医学生物检材检验的重要手段之一。     

论数码照相在刑事技术领域中的应用

数码照相是近十年来新兴的现代摄影技术 ,具有传统摄影技术不可比拟的优点 ,目前 ,已广泛应用于刑事技术领域中的证件照片、刑事现场照相、尸体辨认照片、模糊图像信息处理、照片资料存档等各个方面。至于在记录常规痕迹物证方面 ,尽管业内一部分人士尚存有惟恐“照片失真”的担心 ,但只要制定出严格的行业标准 ,借以规范痕迹物证数码照相的操作 ,就能够趋利避害 ,充分发挥数码照相的优势 ,使数码照相在刑事技术领域中发挥越来越大的作用。     

From Sancitity to Screening: Genetic Disabilities, Risk and Rhetorical Strategies in Wrongful Birth and Wrongful Conception Cases

This analysis scrutinises the rhetorical strategies used by judges in wrongful life and wrongful birth actions as evidence for the assertion that the judicial reading of public policy in such cases has undergone a significant shift which is likely to accelerate as genetic knowledge grows and health care resources shrink. The implications of the predicted move towards increased genetic testing of prospective parents are traversed in relation to feminist analyses of the impact of genetics on reproductive technology. These are viewed as forming a nexus with the current social constructions of disability and the contemporary cultural preoccupation with risk, in a context of the increasing commercial importance of genetic information. It is argued that women cannot make free and informed choices about genetic testing and pregnancy unless legal and social mechanisms which protect those choices are in place.
