The Effect of Image Quality and Forensic Expertise in Facial Image Comparisons

Images of perpetrators in surveillance video footage are often used as evidence in court. In this study, identification accuracy was compared for forensic experts and untrained persons in facial image comparisons as well as the impact of image quality. Participants viewed thirty image pairs and were asked to rate the level of support garnered from their observations for concluding whether or not the two images showed the same person. Forensic experts reached their conclusions with significantly fewer errors than did untrained participants. They were also better than novices at determining when two high‐quality images depicted the same person. Notably, lower image quality led to more careful conclusions by experts, but not for untrained participants. In summary, the untrained participants had more false negatives and false positives than experts, which in the latter case could lead to a higher risk of an innocent person being convicted for an untrained witness.     

Controlling Regulatory Agencies

This article describes the regulatory agencies in Norway as part of the population of state agencies by focusing on who controls and what is controlled and how. The authors analyze whether regulatory agencies are regulated and controlled to different degrees, by different external actors, and in different ways than other agencies, and on whether this control focuses on different aspects. They also examine whether the variation in regulation and control according to type of agency task is sustained if one controls for structural and cultural features. The empirical basis is a broad survey of Norwegian state agencies carried out in 2004, and the theoretical approaches embrace a task-specific, a structural-instrumental and a cultural-institutional perspective. The authors find that regulatory tasks represent a major activity for state agencies in Norway and that external control by both the executive and the legislative bodies of agencies is rather significant. Moreover, in contrast to what one would expect, given current regulatory orthodoxy, regulatory agencies are controlled to a larger extent than other agencies.     

Women and radio: sounding out new paths in women's history

ABSTRACT

Since its early introduction in the domestic sphere in the 1920s, radio has been used as a medium for the expression of women's voices, needs and concerns. In this introduction we would like to mobilise an understanding of radio as a vital source for doing women's history. Women's radio programming, women broadcasters, and women listeners provide a lens through which a number of histories can be analysed. This introduction provides an overview of the historical relationship between women and radio. It is further dedicated to research that explores the overlapping spaces of radio and women's history, and in particular, points to how radio-related source material can provide new points of departure for women's history.     

much less religious,a little more spiritual: the religious and spiritual views of third-wave feminists in the UK

How religious or spiritual are feminists today? Filling a gap in the literature on feminism and religion, this article outlines findings from the first survey-based study of feminists’ spiritual attitudes in recent years. Drawing on survey data, this article explores the religious and spiritual views of 1,265 third-wave feminists, most of whom are women in their twenties and thirties. Comparison with surveys of religious adherence in the UK reveals that these feminists are significantly less religious and somewhat more spiritual than the general population. The article goes on to ask why this might be, and suggests three explanations: feminism's alignment with secularism, secularization and feminism's role within it, and feminism's association with alternative spiritualities.     

Relative effects of posture and activity on human height estimation from surveillance footage

Height estimations based on security camera footage are often requested by law enforcement authorities. While valid and reliable techniques have been established to determine vertical distances from video frames, there is a discrepancy between a person's true static height and their height as measured when assuming different postures or when in motion (e.g., walking). The aim of the research presented in this report was to accurately record the height of subjects as they performed a variety of activities typically observed in security camera footage and compare results to height recorded using a standard height measuring device. Forty-six able bodied adults participated in this study and were recorded using a 3D motion analysis system while performing eight different tasks. Height measurements captured using the 3D motion analysis system were compared to static height measurements in order to determine relative differences. It is anticipated that results presented in this report can be used by forensic image analysis experts as a basis for correcting height estimations of people captured on surveillance footage.     

Translating sexual assault prevention from a college campus to a United States military installation: piloting the know-your-power bystander social marketing campaign

One population that shares both similar and different characteristics with traditional college-age students is the U.S. Military. Similarities include a high concentration of 18- to 26-year-olds dealing with new found independence, peer pressure, and the presence of social norms that support violence and hypermasculinity. Sexual violence is a major public health problem in the United States, and because of the similarities in the age group of college and military populations, the problems regarding sexual violence in both constituencies have been well-documented. In the current pilot study we seek to add to both current knowledge about and promising practices of translating prevention strategies from one target audience to another. We describe how we translated, administered, and evaluated a bystander intervention social marketing campaign focused on sexual assault prevention that had been found to significantly affect attitude change on a college campus for a U.S. Army installation in Europe. In addition to demonstrating the process of translating prevention strategies across target audiences, findings from this pilot study contribute to the evaluation data on the effectiveness of sexual violence prevention strategies implemented with members of the U.S. Military. From our analysis, we see that research participants indicate that the degree to which the images resonate with them and the familiarity of the context (i.e., social self-identification) significantly effect the participants' personal responsibility for reducing sexual assault, confidence in acting as a bystander, and reported engagement as a bystander.     

Comparing Standard and Selective Degradation DNA Extraction Methods: Results from a Field Experiment with Sexual Assault Kits,

A growing number of U.S. cities have large numbers of untested sexual assault kits (SAKs) in police property facilities. Testing older kits and maintaining current case work will be challenging for forensic laboratories, creating a need for more efficient testing methods. Methods: We evaluated selective degradation methods for DNA extraction using actual case work from a sample of previously unsubmitted SAKs in Detroit, Michigan. We randomly assigned 350 kits to either standard or selective degradation testing methods and then compared DNA testing rates and CODIS entry rates between the two groups. Results and conclusions: Continuation‐ratio modeling showed no significant differences, indicating that the selective degradation method had no decrement in performance relative to customary methods. Follow‐up equivalence tests indicated that CODIS entry rates for the two methods could differ by more than ±5%. Selective degradation methods required less personnel time for testing and scientific review than standard testing.
