Change blindness can cause mistaken eyewitness identification

The current study investigated the effects of change blindness and crime severity on eyewitness identification accuracy. This research, involving 717 subjects, examined change blindness during a simulated criminal act and its effects on subjects' accuracy for identifying the perpetrator in a photospread. Subjects who viewed videos designed to induce change blindness were more likely to falsely identify the innocent actor relative to those who viewed control videos. Crime severity did not influence detection of change; however, it did have an effect on eyewitness accuracy. Subjects who viewed a more severe crime ($500 theft) made fewer errors in perpetrator identification than those who viewed a less severe crime ($5 theft). This research has theoretical implications for our understanding of change blindness and practical implications for the real‐world problem of faulty eyewitness testimony.     

He‐said–she‐said: Contrast effects in credibility assessments and possible threats to fundamental principles of criminal law

Purpose. Some criminal trials turn on evaluations of credibility of the complainant and the accused. When credibility is based on how a witness testifies, an evaluation of one party should not influence an evaluation of the other party. If credibility evaluations are bidirectional, fundamental principles of criminal law may be offended. Methods. Six hundred and thirty seven undergraduates read a vignette that described a sexual assault (SA) or a motor vehicle accident (MVA). Karen, the complainant in the SA case and bystander witness in the MVA case, was described as 5, 13, or 20 years old. The vignette was a summary of the police investigation and, in three conditions, the trial. Trial information was manipulated in one of three ways: no information concerning how Karen testified, Karen's testimony was described positively (pro‐prosecution), or described negatively (anti‐prosecution). Participants then rated the perceived credibility of Karen and the accused (Bob) and the probability that Bob was guilty. Results. Karen was viewed more positively in the pro‐prosecution condition and more negatively in the anti‐prosecution. When Karen was judged to be less credible, Bob was rated as more credible and less likely to be guilty. When Karen was seen as more credible, Bob was viewed as more likely to be guilty. Conclusions. This bidirectional effect that the manner in which the prosecution witness testified affected perceptions of the accused and probability of guilt, in certain circumstances, may compromise fundamental principles of criminal law and be a reversible error. We offer possible solutions for future empirical testing.     

2009 H1N1 Fatalities: The New Mexico Experience

Abstract: Histopathologic features of New Mexico 2009 H1N1 fatalities have not been representative of those reported nationwide. We retrospectively reviewed medical records of all New Mexico 2009 pandemic influenza A (pH1N1) fatalities (n = 50). In cases in which autopsy was performed (n = 12), histologic sections and culture results were examined. In contrast to previously published studies, the majority of our fatalities did not have diffuse alveolar damage (DAD) (2/12; 16.7%). Common findings included pulmonary interstitial inflammation and edema, tracheobronchitis, and pneumonia. Two cases had significant extra‐pulmonary manifestations: myocarditis and cerebral edema with herniation. The majority had a rapid disease course: range from 1 to 12 days (median, 2 days), and Native Americans were disproportionately represented among fatalities. These findings suggest that New Mexico H1N1 fatalities generally did not survive long enough to develop the classic picture of DAD. Pathologists should be aware that H1N1 may cause extra‐pulmonary pathology and perform postmortem cultures and histologic sampling accordingly.     

Security-oriented cloud computing platform for critical infrastructures

The rise of virtualisation and cloud computing is one of the most significant features of computing in the last 10 years. However, despite its popularity, there are still a number of technical barriers that prevent it from becoming the truly ubiquitous service it has the potential to be. Central to this are the issues of data security and the lack of trust that users have in relying on cloud services to provide the foundation of their IT infrastructure. This is a highly complex issue, which covers multiple inter-related factors such as platform integrity, robust service guarantees, data and network security, and many others that have yet to be overcome in a meaningful way. This paper presents a concept for an innovative integrated platform to reinforce the integrity and security of cloud services and we apply this in the context of Critical Infrastructures to identify the core requirements, components and features of this infrastructure.     

Influences of Childhood Abuse on Parenting Perspectives of Pregnant Cohabitors

Using thematic analysis, we examine the effects of childhood abuse regarding parenthood for pregnant cohabitors from qualitative interviews. Participants (N?=?18; 10 women and 8 men) recalled childhood abuse during the Adult Attachment Interview. Three themes emerged: (1) “Learning what not to do,” whereby abuse is discussed as something not to continue, and harmful toward children; (2) “Use but modify parents’ discipline,” whereby individuals state that they will employ methods of their parents, but in ways different for their children; and (3) “Ambiguous,” whereby discussions are unclear and confused about how the abuse will affect their parenting. These results suggest that even when pregnant cohabitors want to parent differently than their own parents, they may not have relevant models or skills. For practitioners, we suggest interventions aimed at providing alternative models for how to parent, and effective and appropriate disciplining methods, as ways to deter intergenerational abuse.     

Performance Measures,Ranking and Parental Choice: An Analysis of the English School League Tables

ABSTRACT

Parental choice among schools in England is informed by annually published school performance (league) tables. The 2006 league tables included a measure of contextual value added (CVA) for the first time. By explicitly accounting for the characteristics of a school's intake, the aim is that CVA should isolate the impact a school has on its pupils' progress and so provide a measure of school effectiveness. In this paper we use UK government administrative data to replicate CVA and other key performance measures in order to investigate the extent to which the current league tables provide the information necessary to support parental choice on the basis of school effectiveness. We find that school rankings based on CVA are largely uninformative for parents: almost half of English secondary schools are indistinguishable from the national average level of CVA.
