Latin American critical (‘Social’) epidemiology: new settings for an old dream

The present paper offers a fresh perspective from the South about the relevance of progressive Latin American public health (termed ‘collective health’) by highlighting a number of its hard scientific contributions which, unfortunately, remain almost unknown to mainstream medical and public health researchers outside Latin America. An armed form of structural greed has now placed the world on the brink of destruction. At the same time, however, fresh winds blow in the continent. This paper is an invitation to confront the menacing forces producing our unhealthy societies and an opportunity to form fraternal partnerships on the intercultural road to a better world, where only an epidemiology of dignity and happiness will make sense.

Health Impact Assesment: Hints and Cautions from Critical Epidemiology

Under the format of this conference, to convey the possibilities for health impact assessment of Latin American Critical Epidemiology, sometimes referred to under the tautological designation of “social epidemiology”, I will try to sum up in the next few minutes some reflections based on them.

The subversion of the good life (enlightened rebelliousness for the 21st century: a critical perspective on the work of Bolívar Echeverría)

El debate sobre el modelo civilizatorio de la modernidad de Occidente, consu economía concentradora y excluyente, y su matriz económico energética petrolera y extractivista no sustentable, ha reavivado en los escenarios políticos y académicos de la salud la discusión de la propuesta del buen vivir inscrita en las nuevas constituciones de Bolivia y Ecuador. Ante la crisis social, sanitaria y ambiental producida por la imposición de una economía de la muerte, y la consiguiente multiplicación de modos de vivir malsanos, se discuten aquí las tesis de Bolívar Echeverría sobre la base material de la vida y la cultura, como una herramienta para evaluar históricamente los desempeños de los gobiernos de las izquierdas realmente existentes, y trabajar un modelo de transición histórica y el indispensable remozamiento de la conciencia crítica desde una visión radicalmente renovadora, pero que mire la realidad sin dogmatismo, sin estridencias míticas y con un sentido de profunda autocrítica.

Feminism and IR and the Conditions for Critical Dialogue

My objective in this paper is to problematize the call for dialogue and engagement between feminists and non-feminist International Relations (IR) scholars. I will concentrate on two pieces of scholarship to discuss the issue of dialogue: first, Robert Keohane’s “Beyond Dychotomies: Conversations between International Relations and Feminist Theory’s” (Keohane, 1998); and second, Anne Tickner’s (1997) “You Just don’t Understand: Troubled Engagements between Feminists and IR Theorists.” In both pieces the question of dialogue is of most importance.

The biometeorology of high-altitude insect layers.

Flight at high altitude is part of a migration strategy that maximises insect population displacement. This thesis represents the first substantial analysis of insect migration and layering in Europe. Vertical-looking entomological radar has revealed specific characteristics of high-altitude flight: in particular layering (where a large proportion of the migrating insects are concentrated in a narrow altitude band). The meteorological mechanisms underpinning the formation of these layers are the focus of this thesis. Aerial netting samples and radar data revealed four distinct periods of high-altitude insect migration: dawn, daytime, dusk, and night-time. The most frequently observed nocturnal profiles during the summertime were layers. It is hypothesised that nocturnal layers initiate at a critical altitude (200–500 m above ground level) and time (20:00–22:00 hours UTC). Case study analysis, statistical analysis, and a Lagrangian trajectory model showed that nocturnal insect layers probably result from the insects’ response to meteorological conditions. Temperature was the variable most correlated with nocturnal insect layer presence and intensity because insects are poikilothermic, and temperatures experienced during high-altitude migration in temperate climates are expected to be marginal for many insects’ flight. Hierarchical effects were detected such that other variables—specifically wind speed—were only correlated with insect layer presence and intensity once temperatures were warm. The trajectory model developed comprised: (i) insect flight characteristics; (ii) turbulent winds (which cause vertical spread of the layer); and (iii) mean wind speed, which normally leads to horizontal displacements of hundreds of kilometres in a single migratory flight. This thesis has revealed that there is considerable migratory activity over the UK in the summer months, and a range of fascinating phenomena can be observed (including layers). The UK has moved from one of the least studied to perhaps the best studied environments of aerial insect migration and layering in the world.
