Police perceptions of ADHD in youth interviewees

Attention-deficit hyperactivity disorder (ADHD) in witness-victim/suspect interviews holds strong relevance for policing. Four purpose-written vignettes were used to test the extent to which ADHD interviewee behaviour impacts on the work of 46 experienced Australian detectives and their ability to identify ADHD as a likely diagnosis. Detectives reported frequently encountering ADHD-type interviewees in their work; perceiving such interviewees to be at a very significant risk of future contact with the criminal justice system; and perceiving ADHD-type behaviour to exert a highly significant impact on interviewing time efficiency as well as quality. Detectives gave highly significant ratings of ADHD as a likely explanation of vignettes describing ADHD-type behaviour for witness-victims as well as suspects. However, they could not identify ADHD as the most likely explanation over and above other possibilities. Implications are discussed in terms of a rationale for future research targeting police awareness and training needs in ADHD.     

Differential effects of general versus cued invitations on children’s reports of a repeated event episode

The ability to describe individual episodes of repeated events (such as ongoing abuse) can enhance children’s testimony and assist the progression of their cases through the legal system. Open-ended prompts have been advocated as a means to assist children in accurately retrieving information about individual episodes. In the current study, two subtypes of open-ended prompts (cued and general invitations) were compared for their effects on five- to nine-year-olds’ (n?=?203) reports about individual episodes of a repeated event. Interviews occurred 1–2 weeks after the last of 4 event sessions. Cued invitations assisted children to provide specific details about individual episodes of a repeated event, while general invitations were useful to elicit more broad happenings of the episodes. The accuracy of responses to general invitations was similar for children of all ages up to one week after the event, but at a longer interview delay younger children were less accurate than older children. There were no differences in the accuracy of responses to cued invitations as a function of age or interview delay. Results suggest that interviewers tasked with eliciting accounts of individual episodes from a repeated event, such as ongoing abuse, should consider the differential efficacy of each prompt-type on children’s reports.     

群体性突发事件中的网络谣言分析及控制策略

网络谣言几乎与群体性突发事件如影随形,贯穿于群体性突发事件的全过程,对群体性突发事件的孕育、发生、演变甚至结束都起着重要的影响。纵观近年来处置网络谣言危机的实践,我们可以发现部分地方政府部门在应对网络谣言时缺乏敏感度和预警性,缺乏舆论引导的积极性、主动性,缺乏总结反思和持续关注,不仅影响了群体性突发事件的顺利解决,甚至激化了矛盾,使事态进一步扩大。因此,政府部门必须针对网络谣言在各个阶段的不同特点,制定不同的网络谣言控制策略,增强信息的透明度,有针对性地加强对网络谣言的控制。

Nationalist discourse and the ultra-conservative press in contemporary Poland: a case study of Nasz Dziennik

After the democratic transition to post-Communist Poland, ultraconservative groups found themselves legitimately able to propagate a nationalist ideology. They focused on an idea of ‘national identity’ that clearly and restrictively defined the boundaries of the national community. In the late 1990s a far-right movement supported by a radical faction of the Roman Catholic Church gained wide public support and, eventually, political legitimization. The fears of those for whom the transition of the socio-economic system did not bring a change for the better have been exploited by activists and institutions that consistently point to various foreign ‘threats’ (external and internal) against Poland’s political and economic independence and against national integrity. Starnawski analyses forms of anti-pluralist backlash as strategies undertaken by the ultra-conservative media. Provided is a case study of Nasz Dziennik, one of the major Polish newspapers to disseminate a far-right discourse that combines a concept of ‘national identity’ with radical Catholicism. Such nationalistoriented media use rhetoric that claims to be representative of the dominant group, and attempt to provide the audience with a restrictive sense of identity that is based on the construction of elements that are considered foreign and threatening to a sense of nationhood, a mobilization of the audience against foreign ‘threats’, and the exclusion or marginalization of elements depicted as incongruous with collective identity, especially the cultures of national and ethnic minorities (both ‘native’ minorities and recent immigrants), minority religions and alternative cultures, as well as liberal advocates of diversity. Since Polish society is in large part culturally homogeneous, its members are more often exposed to stereotyped images of minority groups than they are to face-to-face contact with members of minorities. Therefore, Starnawski argues, exploring the contemporary nationalist discourse in ‘pluralizing’ societies such as Poland is no less essential for the diagnosis of anti-democratic obstacles than studying the actual conditions of minority groups themselves. The future of social and cultural pluralism in Poland heavily depends on the majority’s awareness of diversity and its ability to promote attitudes of openness to and understanding of cultural differences on the one hand, and a readiness to extend the notion of ‘Polishness’ to a wide range of cultural and social categories on the other.     

The Kodak Syndrome: Risks and Opportunities Created by Decentralization of Forensic Capabilities

Forensic science laboratories are being challenged by the expanding decentralization of forensic capabilities, particularly for digital traces. This study recommends laboratories undertake digital transformations to capitalize on the decentralization movement, develop a more comprehensive understanding of crime and security‐relevant problems, and play a more central role in problem‐solving collaboratively with law enforcement organizations and other stakeholders. A framework for the bilateral transfer of information and knowledge is proposed to magnify the impact of forensic science laboratories on abating crime, strengthening security, and reinforcing the criminal justice system. To accomplish digital transformations, laboratories require personnel with different expertise, including investigative reasoning, knowledge codification, data analytics, and forensic intelligence. Ultimately, this study encourages managers, educators, researchers, and policymakers to look beyond the usefulness of forensic results for solving individual investigations, and to realize the value of combined forensic knowledge and intelligence for developing broader strategies to deal with crime in digitalized society.     

Digital Stratigraphy: Contextual Analysis of File System Traces in Forensic Science

This work introduces novel methods for conducting forensic analysis of file allocation traces, collectively called digital stratigraphy. These in‐depth forensic analysis methods can provide insight into the origin, composition, distribution, and time frame of strata within storage media. Using case examples and empirical studies, this paper illuminates the successes, challenges, and limitations of digital stratigraphy. This study also shows how understanding file allocation methods can provide insight into concealment activities and how real‐world computer usage can complicate digital stratigraphy. Furthermore, this work explains how forensic analysts have misinterpreted traces of normal file system behavior as indications of concealment activities. This work raises awareness of the value of taking the overall context into account when analyzing file system traces. This work calls for further research in this area and for forensic tools to provide necessary information for such contextual analysis, such as highlighting mass deletion, mass copying, and potential backdating.
