Anatomía Cerebral del mono araña Ateles geoffroyi estudiada utilizando imágenes de resonancia magnética. Primer reporte: estudio comparativo con el cerebro humano Homo Sapiens

El objetivo del presente estudio cualitativo fue analizar los aspectos morfológicos de la anatomía cerebral interna utilizando imágenes de resonancia magnética (IRM) en dos especies de primates, El mono Araña (A. geoffroyi) y el humano (H. sapiens), tomando como base un estudio comparativo de las estructuras cerebrales de las dos especies, concentrándose primordialmente en el sistema límbico del cerebro del mono araña. Aunque es una especie común en el hemisferio occidental, es interesante para estudiar dada su organización social y funciones motoras, el mono araña (A. geoffroyi) ha sido poco estudiado en cuanto a su neuroanatomía. Las IRM fueron hechas a un mono araña utilizando un resonador General Electrics Signa 1.5 T. Esta investigación se llevo a cabo conforme a las leyes internacionales para la protección de animales en cautiverio y teniendo en cuenta todas las medidas de protección para el manejo experimental para evitar cualquier efecto residual de índole comportamental o fisiológico. Desde un punto de vista cualitativo, los cerebros del mono araña y el humano tenían estructuras similares. Con respecto a la forma, las estructuras más parecidas fueron encontradas en el sistema límbico, sin embargo la curvatura cervical, la amígdala, el hipocampo, la comisura anterior y el colículo fueron más grandes proporcionalmente en el mono araña que en el humano.

Socioterritorials forms of appropiation of living and right to the differencial space

The aim of this work is to recover Henri Lefèbvre's methodological contributions for (re)thinking the right to the city, based on the need to know the appropriation of space´s dialectical triad. Empirically, it refers to the urban genesis of Mar del Plata (Argentina), an intermediate Latin American city, and its heterogeneous socio-territorial forms of appropriating inhabitance, or different forms of appropriating goods of use, that lead to think about opening to the transformation of the capitalist social order, and of its urban order, naturalized after the fetischism of private property.

Market access in the western hemisphere: implications for the Andean Community

Este estudio busca contribuir a la evaluación del impacto económico que una mayor liberalización comercial en el Hemisferio Occidental, puede tener sobre los países miembros de la Comunidad Andina. Los escenarios de liberalización comercial más significativos se identifican y simulan, mediante el uso del modelo GTAP en su versión estándar de rendimientos constantes a escala. Los resultados básicos indican una muy baja coincidencia en la dirección de los cambios de bienestar esperables para los países andinos, bajo los cuatro escenarios analizados. De una forma muy simplificada, puede decirse que una mayor liberalización comercial implica pérdidas de bienestar para Colombia, Perú y Ecuador-Bolivia, en tanto que para Venezuela se encuentran ganancias bajo los escenarios que implementan el Área de Libre Comercio de las Américas y pérdidas bajo el que implementa el Acuerdo de Libre Comercio entre sus socios andinos y Estados Unidos. Los términos de intercambio juegan un papel determinante en estos resultados. En general se mueven en contra de estas economías, con la notoria excepción de Venezuela. Al parecer, los países andinos se han beneficiado en el pasado de la desviación de comercio que otras regiones han sufrido, como consecuencia de los acuerdos preferenciales de comercio en los cuales los primeros han participado. Con la erosión del acceso preferencial a otros mercados, implícita en los escenarios simulados, el aumento en la competencia tanto por el lado de las exportaciones como por el de las importaciones, tiende a ajustar la posición internacional de estos países, trayendo con ello nuevos retos para el manejo de sus economías.

Do we have a right to privacy?

El derecho a la intimidad es un tema que genera grandes debates. Las nuevas tecnologías facilitan mucho la obtención de información privada por parte del gobierno, los medios de comunicación y las empresas, siendo controvertido su uso (para la seguridad y protección de los ciudadanos, para la información sobre asuntos de interés público, etc.). El objetivo del libro es animar a los jóvenes a tener su propia opinión sobre el tema mediante técnicas de pensamiento crítico y creativo, recopilación de información, hechos y otros puntos de vista, y el debate y la discusión.

The right to remain silent : the ethics of invasion and evasion in Paul Sayer’s ''The Comforts of Madness''

Este artigo considera as implicações do silêncio e da ética da experimentação médica no romance de Paul Sayer, The Comforts of Madness, vencedor do prémio Whitbread. O romance de Sayer debruça-se sobre um paciente emestado catatónico, Peter, o qual procura retirar-se para um estado de pura subjetividade como consequência de uma série de eventos traumáticos. Inicialmente tratado num hospital tradicional, é posteriormente transferido para uma clínica experimental onde é submetido a uma série de «tratamento» invasivos e bárbaros com o objectivo de «curá-lo». A abordagem de Sayer dos temas relacionados com a insanidade, o silêncio pessoal e a medicina progressiva levanta questões relativas ao direito do indivíduo de rejeitar o mundo comunitário e à ética de extrair a narrativa retida da narrativa relutante. Ao examinar os processos de normalização e resistência, o romance levanta questões relativamente à ética da inclusão forçada e estabelece uma legitimidade de não-cooperação, o direito ao silêncio, o qual funciona em paralelo com a legitimidade da voz marginalizada. A tendência recente nos estudos literários tem sido no sentido da exposição e promoção das vozes anteriormente ostracizadas pela indústria editorial e pelo público leitor, mas, de um modo geral, este processo tem partido da premissa de que a voz perdida beneficia de tal exposição. Para Sayer, existe o caso igualmente persuasivo relacionado com o reconhecimento do direito à privacidade, em risco de ser preterido numa era de transparência excessiva. Este ensaio discute o modo como o romance de Sayer aborda estas preocupações e salienta a sua consciência do processo complexo de lidar com o indivíduo para quem a recusa a falar corresponde a um gesto social ambíguo.

The “right way” of Hermetism: disputes on Gnostic’s, Pagan’s and Christian’s (re-)visions of the Hermetic phonomenon in late antiquity

This paper aims to understand the phenomenon of Hermetism though the perspective of its process of reception and reproduction in society. It will explore the phenomenon that was the transformation of the Hermetica into a social discourse. The so-called technical and philosophical Hermetica are texts. A text is the result of a production: it is composed by men, and addressed to men. It is important to consider the intentions and values present in a text’s production, and to understand that its process of reception and reproduction in society are, in fact, complex and dynamic.

Global Acceleration and Dispossesion: Regression in the Right to Life and Public Health during Ecuador’s Neoliberal Decades

The present essay’s central argument or hypothesis is, consequently, that the mechanisms accelerating a wealth concentrating and exclusionary economy centred on the benefit and overprotection of big business—with a corresponding plundering of resources that are vital for life—generated forms of loss and regression in the right to healthcare and the dismantling of institutional protections. These are all expressed in indicators from 1990-2005, which point not only to the deterioration of healthcare programs and services but also to the undermining of the general conditions of life (social reproduction) and, in contrast to the reports and predictions of the era’s governments, a stagnation or deterioration in health indicators, especially for those most sensitive to the crisis. The present study’s argument is linked together across distinct chapters. First, we undertake the necessary clarification of the categories central to the understanding of a complex issue; clarifying the concept of health itself and its determinants, emphasizing the necessity of taking on an integral understanding as a fundamental prerequisite to unravelling what documents and reports from this era either leave unsaid or distort. Based on that analysis, we will explain the harmful effects of global economic acceleration, the monopolization and pillaging of strategic healthcare goods; not only those which directly place obstacles on the access to health services, but also those like the destructuration of small economies, linked to the impoverishment and worsening of living modes. Thinking epidemiologically, we intend to show signs of the deterioration of broad collectivities’ ways of life as a result of the mechanisms of acceleration and pillage. We will then collect disparate evidence of the deterioration of human health and ecosystems to, finally, establish the most urgent conclusions about this unfortunate period of our social and medical history.

Unholy compromise in the eurozone and how to right it. CEPS Policy Brief No. 277, 16 July 2012

This paper reviews the causes of the ongoing crisis in the eurozone and the policies needed to restore stability in financial markets and reassure a bewildered public. Its main message is that the EU will not overcome the crisis until it has a comprehensive and convincing set of policies in place; able to address simultaneously budgetary discipline and the sovereign debt crisis, the banking crisis, adequate liquidity provision by the ECB and dismal growth. The text updates and expands on his Policy Brief contributed in the run-up to the emergency European Council meeting at the end of June.

Reviewing the EU ETS review? Report of the CEPS TAsk Force on "Does the ETS market produce the 'right' price signal"? CEPS Task Force Report, 12 November 2012

Drawing on discussions within a CEPS Task Force on the revised EU emissions trading system, this report provides a comprehensive assessment of the pros and cons of the various measures put forward by different stakeholders to address the level and stability of the price of carbon in the EU. It argues that the European Commission, the member states, the European Parliament and other stakeholders need to give serious consideration to introducing some kind of ‘dynamic’ adjustment provision to address the relatively inelastic supply. The report also suggests that there is a need to improve communication of market-sensitive information, for example by leaving the management of the ETS to a specialised body.

A new perspective on Southern hemisphere storm-tracks.

A detailed view of Southern Hemisphere storm tracks is obtained based on the application of filtered variance and modern feature-tracking techniques to a wide range of 45-yr European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA-40) data. It has been checked that the conclusions drawn in this study are valid even if data from only the satellite era are used. The emphasis of the paper is on the winter season, but results for the four seasons are also discussed. Both upper- and lower-tropospheric fields are used. The tracking analysis focuses on systems that last longer than 2 days and are mobile (move more than 1000 km). Many of the results support previous ideas about the storm tracks, but some new insights are also obtained. In the summer there is a rather circular, strong, deep high-latitude storm track. In winter the high-latitude storm track is more asymmetric with a spiral from the Atlantic and Indian Oceans in toward Antarctica and a subtropical jet–related lower-latitude storm track over the Pacific, again tending to spiral poleward. At all times of the year, maximum storm activity in the higher-latitude storm track is in the Atlantic and Indian Ocean regions. In the winter upper troposphere, the relative importance of, and interplay between, the subtropical and subpolar storm tracks is discussed. The genesis, lysis, and growth rate of lower-tropospheric winter cyclones together lead to a vivid picture of their behavior that is summarized as a set of overlapping plates, each composed of cyclone life cycles. Systems in each plate appear to feed the genesis in the next plate through downstream development in the upper-troposphere spiral storm track. In the lee of the Andes in South America, there is cyclogenesis associated with the subtropical jet and also, poleward of this, cyclogenesis largely associated with system decay on the upslope and regeneration on the downslope. The genesis and lysis of cyclones and anticyclones have a definite spatial relationship with each other and with the Andes. At 500 hPa, their relative longitudinal positions are consistent with vortex-stretching ideas for simple flow over a large-scale mountain. Cyclonic systems near Antarctica have generally spiraled in from lower latitudes. However, cyclogenesis associated with mobile cyclones occurs around the Antarctic coast with an interesting genesis maximum over the sea ice near 150°E. The South Pacific storm track emerges clearly from the tracking as a coherent deep feature spiraling from Australia to southern South America. A feature of the summer season is the genesis of eastward-moving cyclonic systems near the tropic of Capricorn off Brazil, in the central Pacific and, to a lesser extent, off Madagascar, followed by movement along the southwest flanks of the subtropical anticyclones and contribution to the “convergence zone” cloud bands seen in these regions.

New perspectives on the Northern Hemisphere winter storm tracks

The aim of this paper is to explore the use of both an Eulerian and system-centered method of storm track diagnosis applied to a wide range of meteorological fields at multiple levels to provide a range of perspectives on the Northern Hemisphere winter transient motions and to give new insight into the storm track organization and behavior. The data used are primarily from the European Centre for Medium-Range Weather Forecasts reanalyses project extended with operational analyses to the period 1979-2000. This is supplemented by data from the National Centers for Environmental Prediction and Goddard Earth Observing System 1 reanalyses. The range of fields explored include the usual mean sea level pressure and the lower- and upper-tropospheric height, meridional wind, vorticity, and temperature, as well as the potential vorticity (PV) on a 330-K isentropic surface (PV330) and potential temperature on a PV = 2 PVU surface (theta(PV2)). As well as reporting the primary analysis based on feature tracking, the standard Eulerian 2-6-day bandpass filtered variance analysis is also reported and contrasted with the tracking diagnostics. To enable the feature points to be identified as extrema for all the chosen fields, a planetary wave background structure is removed at each data time. The bandpass filtered variance derived from the different fields yield a rich picture of the nature and comparative magnitudes of the North Pacific and Atlantic storm tracks, and of the Siberian and Mediterranean candidates for storm tracks. The feature tracking allows the cyclonic and anticyclonic activities to be considered seperately. The analysis indicates that anticyclonic features are generally much weaker with less coherence than the cyclonic systems. Cyclones and features associated with them are shown to have much greater coherence and give tracking diagnostics that create a vivid storm track picture that includes the aspects highlighted by the variances as well as highlighting aspects that are not readily available from Eulerian studies. In particular, the upper-tropospheric features as shown by negative theta(PV2), for example, occur in a band spiraling around the hemisphere from the subtropical North Atlantic eastward to the high latitudes of the same ocean basin. Lower-troposphere storm tracks occupy more limited longitudinal sectors, with many of the individual storms possibly triggered from the upper-tropospheric disturbances in the spiral band of activity.
