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

This article analyses how a gendered perspective on community-based tourism (CBT) contributes to the realisation of identity and sovereignty of quilombos. It examines the potential sustainability of CBT coupled with agro-ecological practices within the context of gendered identity politics. Drawing from in-depth ethnographic and archival research conducted between February and July 2015 at Campinho da Independência (Rio de Janeiro, Brazil), the article discusses how female leaders integrate sustainable agro-ecological practices and CBT with environmental education in what they call ‘ethno-ecological tourism’. This approach to CBT strengthens a proudly defiant version of Afro-Brazilian ethnic identity vis-à-vis the state. 相似文献

This paper links the policy context regarding S&T parks to the objectives and characteristics of the established parks and
incubators in a relatively small, converging European country. S&T parks and incubators in Greece during the past decade and
a half have gradually shifted in terms of ownership and management from university/research institute to the private sector
and in terms of financing from public to private funds, also involving the provision of seed capital and access to venture
capital. This gradual shift toward more private engagement has created a variety of models out of which, it is hoped, successful
innovative companies will emerge in larger numbers than in the past.

Allele frequencies, together with some parameters of forensic interest were estimated for nine STRs included in the AmpF/STR Profiler kit (CSF1PO, D3S1358, D5S818, D7S820, D13S317, FGA, TH01, TPOX and vWA) in a sample of 215 unrelated individuals from Cartagena (Colombia). For all loci, no significant deviations from Hardy-Weinberg equilibrium were observed. Comparative analysis results between our data and those from other Colombian and African population samples revealed significant differences, except with two Colombian Caribbean Coast sub-regions. 相似文献

The absence of a thoroughly developed, working class critique of criminological theory has resulted in bias in the creation
of knowledge regarding crime and deviance. Much as feminist writings illuminated the unique problems related to gender, and
works by those discussing racial and ethnic minorities highlighted the special concerns related to race and ethnicity, a working
class perspective can expose the particular issues having to do with class. A brief discussion will be presented dealing with
the portrayal of working class people in the media, and the complicity of academia in allowing working class stereotypes to
persist. A sketch of a working class perspective will then be developed, and it will be used to critique fourteen of the major
criminological theories today in terms of their relative sensitivities and considerations of the class factor in crime and
justice issues. The final section places each of the fourteen theories on a continuum from those that do not consider the
working class experience at all to those that give the working class experience full consideration.
