This article looks at the promise of technology to revolutionise humanitarian action, especially in terms of the gathering and use of data. With many heralding a ‘data revolution’, the opportunities and enthusiasm for using social media and SMS data in crisis response are on the rise. The article constructs an analytical framework in order to scrutinise the three main claims made on behalf of technologically advanced humanitarian information systems: that they can access data more accurately, more quickly, and alter power relations in emancipatory ways. It does so in relation to two aspects of digital humanitarianism: visual technology and crisis mapping, and big data. The article is partly informed by a historical perspective, but also by interview and other material that suggests some of the claims made on behalf of technology are exaggerated. In particular, we argue that the enthusiasm for the data is vastly outstripped by the capacity to meaningfully analyse it. We conclude by scoping the implications of the future technological evolution of humanitarianism, in particular by examining how technology contributes to what Duffield terms ‘post-modern humanitarianism’.  相似文献

We examined the geographic concentration and persistence of terrorism using the Global Terrorism Database (GTD). The GTD logs all terrorist incidents worldwide using open-source media, and, for 1970–2013, includes over 125,000 incidents from over 200 countries and territories. We examined regional and country-level data; different terrorism forms, severity levels, and timeframes (entire period, five-year periods, and annual); and multiple definitions of “elevated” terrorism. The findings reveal that terrorism is concentrated geographically and temporally. Most countries experience peace or very low levels of terrorism; only a few experience substantial outbreaks; very few experience prolonged terrorism; and even fewer, prolonged severe terrorism.  相似文献

Although the recognition of the adoptive rights of LGBT (lesbian, gay, bisexual, and transgender) couples is a socially salient topic, cross-national variation regarding this issue has been largely underexplored in social science research. With the aid of configurational analysis, this article fills this gap and shows the conditions that explain the recognition of the adoptive rights of homosexual couples in the countries of the EU-27. It is argued that two different paths led to this outcome. All countries where adoptive rights were recognized had higher degrees of secularization and lower levels of social homophobia. In addition, in Northern European countries, the Protestant background and absence of conservative governments for a certain time period seemed to be the determinant. However, for the remaining European countries that recognized these rights, rising levels of gender equality appeared to have a more salient role.  相似文献

This article examines the trajectory of the concepts ‘Third World’ and ‘Third-worldism’ in Uruguay, and attempts to prove that, although Third-worldism developed thoroughly as sensibility, it did not have the same success as ideology. The article examines authors and intellectual groups who reflected on the Third World, and especially on ‘tercerismo’ (Third Position) – understood as a set of ideas related to Third-worldism but not part of Third-worldism as such. It next explains the importance of the thought of Carlos Real de Azúa, identified as the main ideologist of Third-worldism in Uruguay. The research shows as a result that there was great concern about the Third World, especially in the 1960s and the 1970s, expressed in articles, reports and speeches, among others. Nevertheless, a full conceptualisation was never realised, except in the contribution made by Real de Azúa. The article concludes that, paradoxically, ‘tercerismo’ blocked the development of more elaborated third-worldist thought in Uruguay.  相似文献

This article explores how terrorists acting alone or in small groups have used sports events as symbolic targets in their performance of terrorism. Drawing on a comparative analysis of the attacks on the 1996 Atlanta Olympic Games and the 2013 Boston Marathon, it is argued that terrorist target selection of major sports events should be understood in relation to the grievances and desires of the perpetrators. The article finds that rather than being the primary target of their attacks, sports events are among a broader range of densely crowded spaces that terrorist actors may seek to target as part of their violent struggle against their adversaries. The findings are contextualized in relation to broader patterns and trends in lone wolf terrorism, including the significance of a copycat phenomenon and inspiration effect.  相似文献

Eight Y-chromosome STRs were investigated in a male population sample from El Salvador. Complete Y-chromosomal STRs haplotypes were obtained in 121 individuals, among which 107 different haplotypes were observed. The two most common haplotypes were shared by approximately 4% of the sample, while 100 haplotypes were unique. The gene diversity was 0.9883 and the discrimination capacity was 0.8926. The combined Y-chromosome STR polymorphisms provide a powerful discrimination tool for routine forensic applications.  相似文献

DNA typing through analysis of short tandem repeats (STRs) and mitochondrial DNA (mtDNA) by means of the polymerase chain reaction (PCR) and sequencing are the common methods for the forensic identification of persons and reconstruction of kinship, especially when skeletal human remains have to be analyzed. Furthermore, samples typically found at crime scenes may be both quantitatively and qualitatively inadequate since they may contain very scarce and often degraded DNA due to exposure to heat, light, humidity, and microorganisms. In order to improve the performance of STR typing technology in those cases where DNA availability is limited, it would be desirable to have a source of degraded DNA with known properties. For this purpose, we have developed a method to prepare artificially degraded DNA under controlled conditions. By treatment of genomic DNA with sonication and DNAse I we have produced DNA fragments within a defined range of lengths. STR typing of this degraded DNA with a commercially available multiplex kit could only produce partial profiles as indicated by the absence of STR alleles with sizes >200 bp. This artificially degraded DNA can be used for the improvement and standardization of STR typing protocols when only highly degraded DNA is available for analysis.  相似文献
