AbstractThis article reports and discusses the results of a study that investigated photographic images of children in five online terrorist magazines to understand the roles of children in these groups. The analysis encompasses issues of Inspire, Dabiq, Jihad Recollections (JR), Azan, and Gaidi Mtanni (GM) from 2009 to 2016. The total number of images was ninety-four. A news value framework was applied that systematically investigated what values the images held that resulted in them being “newsworthy” enough to be published. This article discusses the key findings, which were that Dabiq distinguished different roles for boys and girls, portrayed fierce and prestigious boy child perpetrators, and children flourishing under the caliphate; Inspire and Azan focused on portraying children as victims of Western-backed warfare; GM portrayed children supporting the cause peacefully; and JR contained no re-occurring findings. 相似文献

The forensic science community raised the need for improved evidence recognition, collection, and visualization analytical instrumentation for field and laboratory use. While the 3D optical techniques for imaging static objects have been extensively studied, there is still a major gap between current knowledge and collecting high‐quality footwear and tire impression evidence. Among optical means for 3D imaging, digital fringe projection (DFP) techniques reconstruct 3D shape from phase information, achieving camera‐pixel spatial resolution. This paper presents a high‐resolution 3D imaging technology using DFP techniques dedicated to footwear and tire impression capture. We developed fully automated software algorithms and a graphical user interface (GUI) that allow anyone without training to operate for high‐quality 3D data capture. We performed accuracy evaluations and comparisons comparing with the commercial high‐end 3D scanner and carried out qualitative tests for various impressions comparing with the current practices. Overall, our technology achieves similar levels of accuracy and resolution with a high‐end commercially available 3D scanner, while having the merits of being (1) more affordable; (2) much easier to operate; and (3) more robust. Compared with the current practice of casting, our technology demonstrates its superiority because it (1) is non‐destructive; (2) collects more evidence detail than casts, especially when an impression is fragile; (3) requires less time and money to collect each piece of evidence; and (4) results in a digital file that can easily be shared with other examiners. 相似文献

A looking glass self-orientation refers to the tendency to incorporate the opinions of social partners to form a self-representation
and approve of one’s self. These orientations were assessed for two adolescent siblings in 438 families with surveys accessed
on-line. Younger (M = 11.6 years, SD = 1.8) and older (M = 14.3, SD = 2.1) siblings and their mothers (82.7% European-American) participated. The siblings shared similar orientations in relying
on either classmates or the other sibling for approval, prior to self approval. Relying on classmate approval was significantly
associated with adjustment and academic performance as reported by both the self and mothers. Siblings were also identified
as sources of approval with implications for adjustment, but the magnitude of the associations with adjustment were lower.
Comparisons of the older and younger siblings revealed that both groups were equally as liable to poor outcomes when reflecting
the opinions of classmates or siblings. The results of SEM analyses implicate parenting characterized as coercive, rejecting,
and chaotic in association with the tendency to rely on others for approval. A mediating role for looking glass self-orientations
in associations between parenting and depressive symptoms, anxiety or academic performance was also found.

Cholesterol and squalene are fatty materials of latent fingermarks that can be utilized for dating methodologies and visualization techniques. Previous studies have suggested these compounds undergo degradation in fingermarks as a function of time (days) and light at ambient temperature. However, studies assessing how their composition changes at low and high temperatures over short periods of time (hours) have not been published previously. Here, we performed quantitative analysis of cholesterol and squalene in natural fingermark residue using PVDF membrane, after exposure to a range of temperatures (−20 to 100°C) for 4 and 8 h. We found that levels of both fatty materials remained constant at −20 to 60°C, but both showed significant reduction at 100°C, over short exposure times. These results indicate that cholesterol and squalene are detectable at −20 to 60°C, whereas at 100°C or higher, both are lost due to rapid thermal degradation. 相似文献

What are the conditions that promote gender equality in political participation? In this article, I propose that the presence of direct democracy expands gender equality in political participation by signaling the system's openness to women's voice, confirming their political competency, and highlighting their stake in political decisions. To test this argument, I leverage a quasi‐experiment in Sweden in the aftermath of the introduction of universal suffrage, where the type of municipal political institutions was determined by a population threshold. My findings lend strong support to the effect of direct democracy on the political inclusion of women. I find that the gender gap in electoral participation was smaller in municipalities using direct democracy than in similarly sized municipalities that only had representative institutions. 相似文献
