In forensics, bloodstains on dark fabrics might be invisible for the naked eye. Although several visualization, presumptive, and confirmatory blood tests have been developed, all have one or more disadvantages, especially on DNA analysis. We report here the use of a visualization assay that can visually detect blood drops up to 1/20 dilution. In this assay, the fabric is placed between two wet filter papers and covered by glass surfaces on both sides. Pressure is applied on the glass surfaces in which bloodstains transfer onto the filter papers through capillary forces. Detected stains can be tested with other more sensitive presumptive blood tests performed on the filter paper. Even more, DNA analysis can be performed on the transferred bloodstains. The presented visualization assay is easy to perform, extremely cheap, requires little hands on time, and does not affect bloodstain pattern analysis. 相似文献

As verb, code and historical method, terrorism has consistently been understood as an act of symbolically intimidating and, if deemed necessary, violently eradicating a personal, political, social, ethnic, religious, ideological or otherwise radically differentiated foe. Yet, as noun, message and catch-all political signifier, the meaning of terrorism has proven more elusive. After the Cold War terror mutated from a logic of deterrence based on a nuclear balance of terror into a new imbalance of terror based on a mimetic fear and an asymmetrical willingness and capacity to destroy the other without the formalities of war. This imbalance is furthered by the multiple media, which transmit powerful images as well as triggering pathological responses to the terrorist event. Thanks to the immediacy of television, the internet and other networked information technology, we see terrorism everywhere in real time, all the time. In turn, terrorism has taken on an iconic, fetishised and, most significantly, highly optical character. 相似文献

This paper discusses how urban informality in the developing world has been understood in the West, and how it has been incorporated in the discourse of urban architects and planners in the developed world. It proposes a genealogy of this understanding through the identification of discourses with major ideological currents. It explains the evolution of the relationship between the understanding of urban informality and anarchism; the empowerment of the urban poor and finally the role of this understanding as a neoliberal discourse against state intervention. It finds that, although the incorporation of urban informality in urban architectural discourses is presented as a relative novelty, it is in reality at least 60 years old, dating from John Turner’s writings about the barriadas of Lima. From a progressive and empowering understanding of how the grassroots are able to take their lives into their own hands, it has become a tool for neoliberal discourses defending the dismissal of the state as a valid articulator of urban development. 相似文献

This study investigates the diversity in impact of innovation platforms (IPs) on agricultural networks and technology adoption among 1200 households in nine sub-Saharan Africa countries. We explore the extent to which the 32 IPs implemented adopted the Integrated Agricultural Research for Development Approach (IAR4D). We find that IPs implemented according to the IAR4Dness principles are better at promoting networks of households with other farmers within villages. We find that IPs with more active members were more successful in promoting agricultural technologies, while IPs with many different stakeholders were less successful in promoting agricultural technologies. 相似文献

Abstract The use of swearwords has hardly been investigated scientifically. Virtually nothing is known about the efficacy of swearing. The present studies set out to investigate whether the inclusion of swearwords in a testimony increases the believability of that statement. In study 1, respondents were simply asked whether they believed that using swearwords is a sign of credibility, a sign of deceit, or neither. In the second and third study, participants had to read fictitious testimonies of a suspect and a victim, respectively. Participants were exposed to testimonies with or without swearwords. The results suggested that people self-reported to find swearwords a sign of deceit (study 1), but when actually confronted with a statement, the opposite turned out to be the case (studies 2 and 3). That is, testimonies containing swearwords were perceived as more credible than swearword-free testimonies. Hence it is concluded that swearing increases believability of statements. 相似文献

Abstract We report on delinquency for 270 males after residential treatment in a juvenile justice institution in the Netherlands. We describe personality characteristics, relations with peers, school and family, as well as treatment characteristics. Next, we describe post-release offending based on reconviction data, and relate this to background characteristics, differentiating between serious and violent offending. In doing so, we distinguish between incidental offenders, chronic offenders and desisters. 相似文献

This paper proposes a general framework of criminal decision making that assumes both ‘cool’ cognition and ‘hot’ affect, i.e. feelings, to influence criminal choice. Drawing from judgment and decision making research and social psychology, the hot/cool perspective extends rational choice and deterrence theories by explaining how affect is likely to influence criminal decisions alongside cognitive considerations, such as the perceived costs and benefits of crime. It is shown how the hot/cool perspective offers a more realistic account of criminal decision making processes than existing decision models and approaches and also allows for the explanation of criminal behaviors that are difficult to explain in terms of rational choice. 相似文献

This paper examines the partner selection of the lower classes during an urban crisis period in early industrial Belgian cities. It was found that in this period characterized by an economic transition, overpopulation, migration and a low standard of living, social heterogamy was high, whereas social homogamy increased, or was ‘restored’, in the subsequent period. The urban crisis effect on partner selection contradicts the claims of modernization theory that there was a gradual increase in societal openness and that societal openness was typically modern, but it fits the idea of the informalization of marriage, a process marked by an increase in unmarried cohabitation and illegitimacy. 相似文献
