Governing Terrorism through Preemption: A Comparative Analysis of Radicalization in Three Western Liberal Democracies
In recent years, issues related to terrorism and counterterrorism are increasingly being understood through the construct of ‘radicalization.’ At its most basic level, radicalization is most often conceptualized as a transition from “normal,” conventional political, religious or otherwise ideological beliefs towards extremist views and ultimately violence. The process is now adopted by governmental officials and politicians, police authorities, journalists, and even scientists to justify various forms of governmental intervention, such as policing, social and public policy, education, and surveillance. Notably missing from the scholarly literature is a distinctly sociological understanding of the implications of the proliferation of radicalization discourse in contemporary society. Considering the relative absence of sociological research on radicalization as a construct, this project develops a theoretical perspective based on insights from the sociology of social control to explore the emergence and genesis of radicalization discourse and its social implications.
In particular, this study engages with theories of governmentality, literature within critical policing studies and the othering paradigm traced back to the work of Edward Said, to explore the global diffusion of radicalization discourses across three Western liberal democracies – the United States, United Kingdom, and Canada – from 1969 to the present. More specifically, utilizing critical discourse and case study analysis, I explore how social institutions of law, politics, media, and science conceptualize radicalization and investigate the material practices of risk, security, and policing for which such discourses give rise. Following the analysis of thousands of publicly available governmental and non-governmental documents, this study finds that not only has radicalization become a dominant framework for understanding terrorism, but that modern discursive labeling mechanisms associated with preemption disproportionately affect certain cultural and ethnic minorities. The data illustrate this trend across social institutions in all three countries. The findings also highlight how notions of risk and security are increasingly embedded in the daily lives of citizens through discourses of radicalization in order to more efficiently govern the threat of terrorism. The study therefore broadens sociological and criminological debates on processes of social exclusion, social control, and cultural change in the context of terrorism and highlights some of the ways in which social distance is constructed and represented in the public sphere
Population expansion in the North African Late Pleistocene signalled by mitochondrial DNA haplogroup U6
Background
<br/>
The archaeology of North Africa remains enigmatic, with questions of population continuity versus discontinuity taking centre-stage. Debates have focused on population transitions between the bearers of the Middle Palaeolithic Aterian industry and the later Upper Palaeolithic populations of the Maghreb, as well as between the late Pleistocene and Holocene.
<br/>
Results
Improved resolution of the mitochondrial DNA (mtDNA) haplogroup U6 phylogeny, by the screening of 39 new complete sequences, has enabled us to infer a signal of moderate population expansion using Bayesian coalescent methods. To ascertain the time for this expansion, we applied both a mutation rate accounting for purifying selection and one with an internal calibration based on four approximate archaeological dates: the settlement of the Canary Islands, the settlement of Sardinia and its internal population re-expansion, and the split between haplogroups U5 and U6 around the time of the first modern human settlement of the Near East.
<br/>
Conclusions
<br/>
A Bayesian skyline plot placed the main expansion in the time frame of the Late Pleistocene, around 20 ka, and spatial smoothing techniques suggested that the most probable geographic region for this demographic event was to the west of North Africa. A comparison with U6's European sister clade, U5, revealed a stronger population expansion at around this time in Europe. Also in contrast with U5, a weak signal of a recent population expansion in the last 5,000 years was observed in North Africa, pointing to a moderate impact of the late Neolithic on the local population size of the southern Mediterranean coast
Craniotomia Orbitozigomática Em Três Peças: Dicas E Truques
Objective: Didactically describe the orbitozygomatic craniotomy made in three pieces. Method: This approach was performed, from 2002 to 2011, in 49 patients admitted at Beneficência Portuguesa of São Paulo Hospital. Results: Twenty-seven patients had vascular lesions and twenty-two suffered for intracranial skull base tumors. The vascular lesions varied from cavernous angiomas inside the mesencephalum, high bifurcation basilar tip aneurysms, superior cerebellar arteries aneurysms and arteriovenous malformations in the interpeduncular cistern. Skull base tumors as meningiomas, interpeduncular hamartomas and third ventricle floor gliomas were among the neoplastic lesions approached. We had no permanent injuries and minimal transient complications had occurred. Conclusion: It is a descriptive text, organized in the sequence of the main stages in which such a craniotomy is performed, describing in details the technique in which this group of evolutionarily authors came to accomplish the task. © 2016, Associacao Arquivos de Neuro-Psiquiatria.

The Deformable Universe
The concept of smooth deformations of a Riemannian manifolds, recently
evidenced by the solution of the Poincar\'e conjecture, is applied to
Einstein's gravitational theory and in particular to the standard FLRW
cosmology. We present a brief review of the deformation of Riemannian geometry,
showing how such deformations can be derived from the Einstein-Hilbert
dynamical principle. We show that such deformations of space-times of general
relativity produce observable effects that can be measured by four-dimensional
observers. In the case of the FLRW cosmology, one such observable effect is
shown to be consistent with the accelerated expansion of the universe.Comment: 20 pages, LaTeX, 3 figure
Fluxo migratório de casos de malária em Cuiabá/MT, 1986
2406 people who searched SUCAM/ Cuiabá for diagnosis and malaria treatment. From these, 1151 were positive for peripheral blood film: 720 P. vivax, 421 P. falciparum and 10 mixed shape. 1255 were negative for hemathozoaries research. The interviews were done through a standard questionary where it was tried to divide people according to their sex, age, profession, birthrigh, month cernings, coming from and to places. Ready analysis show malaria cases come with more intensity from North of Mato Grosso micro region to the Cuiabana lowland (56.5%), putting all this micro region population in risk, which stopped spray DDT in the majority of the places. It's important the flux of malaria cases from Rondônia State to Cuiabá and from Cuiabá to south and southeast States from the country. We concluded that urgent resolution must be taken for the changing of malaria control campaign, planning intervetion in the social, politics and economic aspects.Foram estudadas 2.406 pessoas que procuraram a SUCAM/Cuiabá para diagnóstico e tratamento da malária. Destes, 1.151 tiveram lâminas positivas através da gota espessa: 720 P. vivax, 421 P. falciparum e 10 forma mista; 1.255 foram negativos à pesquisa de hematozoários. As entrevistas foram realizadas através de questionário padronizado onde procurou-se categorizar as pessoas conforme o sexo, idade, profissão, naturalidade, renda mensal, procedência e destino. Da análise efetuada vimos que os casos de malária originaram-se mais da micro-região Norte-Matogrossense para a Baixada Cuiabana (56,5%), colocando em risco toda a população desta micro-região, que encontra-se com borrificaçâo suspensa (DDT) na maioria das localidades. É também importante o fluxo de casos de malária do Estado de Rondônia (20,6%) e para os Estados da região Sul e Sudeste (4,4%) do país. Concluímos que medidas urgentes devam ser tomadas para a reformulação da campanha de controle da malária, planejando a intervenção nos aspectos sociais, políticos e econômicos
MAPEAMENTO DE RISCO GEOMORFOLÓGICO NA COMUNIDADE DO JACÓ - ROCAS - NATAL, RN.
O objetivo deste trabalho é identificar e classificar os pontos mais vulneráveis ao risco de deslizamento na comunidade do Jacó, inserida no bairro das Rocas, Natal/RN. A identificação, estudo e posterior mapeamento da área foram possíveis através de levantamentos bibliográficos, de campo e aplicação da metodologia proposta para a pesquisa (GUERRA, 2009). Dessa forma, foi praticável a obtenção de resultados, no que diz respeito aos pontos mais vulneráveis da área
