Globalização e exclusão: a dialética da mundialização do capital Globalization and exclusion

O propósito deste trabalho é repensar o processo de desenvolvimento do capitalismo, apontando para algumas das inúmeras contradições da sociedade global. São analisadas duas questões fundamentais: o crescente processo de exclusão social, de grande parte da população mundial, e o papel do Estado-Nação. Considera-se esta última questão extremamente relevante, pois diante de uma tendência intrínseca do sistema à concentração da riqueza, de um lado, e a expansão da pobreza, de outro, o Estado se apresenta como a única salvaguarda real dos interesses vitais dos excluídos em cada país. Discutem-se também alguns aspectos da crise atual do sistema capitalista e o impacto do modelo neoliberal no acirramento das contradições sociais e na polarização dos interesses de classe. Propõe-se uma reflexão sobre formas alternativas de organização social.<br>The purpose of this work is to rethink the process of capitalist development, pointing out to some of global society's numerous contradictions. Two central issues are examined: the growing process of social exclusion of a sizable part of the world population and the role of the nation-state. The latter is seen as extremely relevant in the light of the system's intrinsic trend to concentrate wealth while expanding poverty, when the state comes as the only real safeguard for vital interests of those excluded in each country. Some aspects of the current crisis in the capitalist system and the impact of the neoliberal model in deepening social contradictions and polarizing class interests are also discussed. A reflection on alternative forms of social organization is put forward

Sob o signo neoliberal: as relações internacionais da América Latina

As relações internacionais da América Latina são vistas sob o ângulo da transição da diplomacia do desenvolvimento para a diplomacia neoliberal. Os estudos de relações internacionais, particularmente no Brasil e na Argentina, fundamentam a interpretação do autor sobre benefícios e malogros do paradigma neoliberal, visto como uma opção ideológica. A noção de Estado logístico é sugerida como alternativa estratégica ao Estado normal.<br>In this article, international relations in Latin America are analysed through the viewpoint of the transition from a diplomacy of development to a neoliberal model. Studies in International Relations as a discipline, especially those carried out in Brazil and Argentina, are the basis for the author's interpretation about benefits and failures of the neoliberal paradigm, understood as an ideological option. The author forwards the notion of Logistic State as a strategic alternative to the Normal State

FRIPON: a worldwide network to track incoming meteoroids

(IF 5.80; Q1)International audienceContext. Until recently, camera networks designed for monitoring fireballs worldwide were not fully automated, implying that in case of a meteorite fall, the recovery campaign was rarely immediate. This was an important limiting factor as the most fragile-hence precious-meteorites must be recovered rapidly to avoid their alteration. Aims. The Fireball Recovery and InterPlanetary Observation Network (FRIPON) scientific project was designed to overcome this limitation. This network comprises a fully automated camera and radio network deployed over a significant fraction of western Europe and a small fraction of Canada. As of today, it consists of 150 cameras and 25 European radio receivers and covers an area of about 1.5 × 10 6 km 2. Methods. The FRIPON network, fully operational since 2018, has been monitoring meteoroid entries since 2016, thereby allowing the characterization of their dynamical and physical properties. In addition, the level of automation of the network makes it possible to trigger a meteorite recovery campaign only a few hours after it reaches the surface of the Earth. Recovery campaigns are only organized for meteorites with final masses estimated of at least 500 g, which is about one event per year in France. No recovery campaign is organized in the case of smaller final masses on the order of 50 to 100 g, which happens about three times a year; instead, the information is delivered to the local media so that it can reach the inhabitants living in the vicinity of the fall. Results. Nearly 4000 meteoroids have been detected so far and characterized by FRIPON. The distribution of their orbits appears to be bimodal, with a cometary population and a main belt population. Sporadic meteors amount to about 55% of all meteors. A first estimate of the absolute meteoroid flux (mag <-5; meteoroid size ≥∼1 cm) amounts to 1250/yr/10 6 km 2. This value is compatible with previous estimates. Finally, the first meteorite was recovered in Italy (Cavezzo, January 2020) thanks to the PRISMA network, a component of the FRIPON science project
