The meaning of internationalism in Angola:Were the Cubans “exporting” the revolution or becoming “the good colonizers”?

Between 1975 and 1991, Cuba deployed to Angola more than 300 000 military personnel (of which some 2 000 lost their lives), and around 50 000 civilians worked as doctors, nurses, teachers or engineers. The cultural impact of the presence of Cubans in the first half of the civil war in post-independence Angola marked deeply a whole generation of men and women and is still pretty much under-researched. In this article, I discuss the meaning of internationalism in Angola for Cuban society, resorting to sources (literature, poetry, testimony and political speeches) that have been addressing the Angolan conflict and analysing the meaning of Cuba’s internationalist policy stemming from both Cuba and abroad. By showing the mobilizing and activist character of the Cuban experience in Angola, through accounts on internationalism, my argument is that, rather than imposing themselves in a foreign nation, the Cubans were attempting to incorporate Angola in their own national narrative, in the sense of Eric Hobsbawm’s ‘‘ invention of tradition’’.«Exporter » la révolution ou devenir de «bons colonisateurs » ? Le sens de l’internationalisme cubain en Angola. Entre 1975 et 1991, Cuba a déployé en Angola plus de 300 000 soldats (dont 2 000 ont perdu la vie), et envoyé 50 000 civils environ comme médecins, infirmières, enseignants ou ingénieurs. Cette présence cubaine dans la guerre civile postérieure à l’indépendance en Angola a eu un impact culturel profond sur toute une génération d’hommes et de femmes. Elle est restée très peu étudiée. Cet article interroge le sens qu’a eu l’engagement internationaliste en Angola pour la société cubaine, en s’appuyant sur des sources diverses (littérature, poésie, témoignages et discours politiques) qui ont évoqué le conflit en Angola et ont analysé l’internationalisme cubain. En mettant en évidence à partir de témoignages la mobilisation et le militantisme qui caractérisent l’expérience cubaine en Angola, je montre que les Cubains n’ont pas tant cherché à s’imposer à une autre nation qu’à intégrer l’Angola dans leur propre récit national ¢ au sens de «l’invention de la tradition » d’Eric Hobsbawm.Ribeiro Raquel.

Preheating in Dirac-Born-Infeld inflation

We study how the universe reheats following an era of chaotic Dirac-Born-Infeld inflation, and compare the rate of particle production with that in models based on canonical kinetic terms. Particle production occurs through non-perturbative resonances whose structure is modified by the nonlinearities of the Dirac-Born-Infeld action. We investigate these modifications and show that the reheating process may be efficient. We estimate the initial temperature of the subsequent hot, radiation-dominated phase.Comment: 23 page

Efeito da frutose na síndrome metabólica

Trabalho Complementar apresentado à Universidade Fernando Pessoa como parte dos requisitos para obtenção do grau de licenciada em Ciências da NutriçãoIntrodução: A síndrome metabólica (SM) é considerada uma constelação de fatores de risco cardiometabólicos que incluem dislipidemia, resistência à insulina (RI), hipertensão arterial (HTA), intolerância à glicose, obesidade abdominal e NAFLD (Estateose hepática não alcoólica), associados a um risco aumentado de diabetes mellitus tipo 2 (DM2) e doenças cardiovasculares (DCV). A frutose é considerada uma das causas para o aumento de incidência desta síndrome. Objetivo: Perceber qual o impacto da ingestão da frutose nos componentes da SM. Métodos: A revisão da literatura foi realizada através de pesquisas feitas na base de dados Pubmed. A pesquisa decorreu entre março e junho de 2015 e os termos utilizados foram: “fructose, metabolic syndrome”, “metabolic effects of fructose” e “fructose, NAFLD”. Foram incluídos nesta revisão sistemática da literatura 23 artigos. Resultados: O consumo de frutose teve impacto em quase todos os componentes da SM, estando associado a aumentos dos triglicerídeos plasmáticos e da glicemia, bem como a diminuição da sensibilidade à insulina e das concentrações do colesterol HDL. Por sua vez, não se observaram efeitos significativos relativamente à pressão arterial. Conclusão: O consumo de frutose parece ter efeitos adversos em quase todos os componentes da SM.Background: Metabolic syndrome (MS) is considered a constellation of cardiometabolic risk factors including dyslipidemia, insulin resistance (IR), high blood pressure (hypertension), glucose intolerance, abdominal obesity and NAFLD (non-alcoholic fatty liver disease), associated with an increased risk of type 2 diabetes mellitus (DM2) and cardiovascular disease (CVD). Fructose is considered one of the causes for the increased incidence of this syndrome. Objective: To understand the impact of fructose intake in MS components. Methods: A literature review was conducted through surveys in Pubmed database. The survey took place between March and June 2015 and the terms used were "fructose, metabolic syndrome," "metabolic effects of fructose" and "fructose, NAFLD." They were included in this systematic literature review 23 articles. Results: Fructose consumption has impacted almost all components of MS and it is associated with increases in plasma triglycerides and blood glucose, and decreased insulin sensitivity and HDL cholesterol concentrations. In turn, there were no significant effects with respect to blood pressure. Conclusion: The fructose consumption seems to have adverse effects on almost all components of MS

Globalização e suas consequências: representações de estudantes e profissionais portugueses = Globalization and its consequences: representations of portuguese students and professionals

RESUMO: A globalização é um grande tema da atualidade. A controversa que gera entre especialistas incide sobre todas as dimensões do fenómeno e suscita atitudes antagónicas sobretudo em relação às suas consequências. O presente estudo procura compreender a opinião do cidadão comum sobre a globalização, nomeadamente respeitante às consequências positivas e negativas do fenómeno em diferentes áreas da vida social. Foram realizadas 30 entrevistas semiestruturadas com estudantes e profissionais do Norte de Portugal, que foram analisadas com o programa de análise textual ALCESTE. O programa classificou 79.05% do material recolhido em quatro classes, evidenciando quatro dimensões importantes da globalização: Mercado e Cultura, Ciência e Tecnologia, Ambiente, e Política e Abertura, dimensões que integram aspetos positivos e negativos. No que respeita às diferenças entre estudantes e profissionais, a análise indica que os estudantes destacam particularmente as consequências da globalização sobre a tecnologia e o ambiente, enquanto os ativos salientam sobretudo as suas consequências políticas ou económicas. De forma mais geral, os resultados evidenciam que existem diferentes processos de globalização com repercussões múltiplas e consequências desiguais sobre a vida social. Palavras-chave: globalização; consequências; desigualdades sociais; representações sociais; Portugal.   ABSTRACT: Globalization is a major present-day issue. The controversy that it creates among experts bears on all the dimensions of the phenomenon and it raises antagonistic attitudes especially in relation to its consequences. The present study aims at understanding lay people’s opinions on globalization, namely with regard to the positive and negative consequences of the phenomenon on different areas of social life. Thirty semi-structured interviews were conducted with students and professionals from northern Portugal, which were analyzed by means of the program for textual data analysis ALCESTE. The program classified 79.05% of the gathered material into four classes, evidencing four important dimensions of globalization: Market and Culture, Science and Technology, Environment, and Politics and Openness, dimensions that integrate positive and negative aspects. With regard to the differences between students and professionals, the analysis indicates that students particularly stress the consequences of globalization on technology and the environment, while professionals emphasize, above all, its political or economic consequences. More generally, the results highlight that there are different processes of globalization with multiple repercussions and unequal consequences on social life.
