The equity gap: Latin America, the Caribbean and the Social Summit

The World Summit for Social Development, held in Copenhagen, Denmark, from 6 to 12 March 1995, brought together a large number of heads of State and Government and official representatives from States Members of the United Nations and culminated in the adoption of the Copenhagen Declaration on Social Development and the Programme of Action of the World Summit for Social Development. These two documents —the first containing policy statements, the other dealing with their practical application— imply commitments at the national, regional and international levels. Barely two years have passed since this summit was held, too short a period to permit an evaluation of the impact of the actions that the Latin American and Caribbean Governments set out to undertake. On the other hand, most of the countries were already implementing a variety of official policies related to the great objectives of the World Summit for Social Development. Al reunirse ahora los países miembros de la CEPAL para examinar, por vez primera, los avances hacia la aplicación de los resultados de la Cumbre,1 la Secretaría ha centrado su estudio en tres aspectos. Primero, en examinar, desde la óptica latinoamericana y del Caribe, la situación actual en materia de pobreza, empleo e integración social, los principales temas de la Cumbre. Segundo, en el ámbito de las políticas, en reseñar las tendencias que resultan más relevantes para el cumplimiento de los compromisos antes mencionados. Tercero, en proponer algunas orientaciones adicionales sobre el contenido y alcance de las políticas tendientes a facilitar el pleno cumplimiento futuro de dichos compromisos. Se procura con ello orientar el debate de los gobiernos y de la sociedad civil en América Latina y el Caribe acerca de cómo se están instrumentando en la región los compromisos de la Cumbre de Copenhague.

Nebraska Pork Summit Remarks

I'd like to begin my brief remarks today with some thank you's. First, thank you, Governor Heineman, for sharing your views with us just now, and for your efforts on behalf of Nebraska agriculture as you work with others to grow Nebraska markets. We also thank you for your strong support of the University of Nebraska.

MORPHOLOGY, MINERALOGY AND MICROMORPHOLOGY OF SOILS ASSOCIATED TO SUMMIT DEPRESSIONS OF THE NORTHEASTERN BRAZILIAN COASTAL PLAINS

The scarcity of comprehensive characterizations of soils associated to gentle summit depressions of the Northeastern Brazilian Coastal Plains justifies this work, which had as objective to provide basic information for the more diverse agricultural and non-agricultural uses. For that, representative soils (Spodosols or similar soils) from these environments were selected in Alagoas, Sergipe and Bahia states. This approach included characterization of morphological, mineralogical and micromorphological properties of the soil profiles, employing standard procedures. The morphological characterization corroborated the effect of the podzolization process during the formation of these soils. The mineralogy of the clay fraction of these soils was basically composed of kaolinite and quartz, which, associated to the very sandy texture, helped in the understanding of the obtained data. The soil micromorphological study, besides confirming the field morphology, mainly in regard to the strong cementation, aggregated value to the work in terms of the secure identification of the clay illuviation process (non-identified in the field), in association with the dominant podzolization process.

Nitrogen oxides in the firn air at Summit, Greenland

Measurements of NOx within the snowpack at Summit, Greenland were carried out from June 2008 to July 2010, using a novel system to sample firn air with minimal disruption of the snowpack. These long-term measurements were motivated by the need of improving the representation of air-snow interactions in global models. Results indicated that the NOx budget within the snowpack was on the order of 550 pptv as maximum, and was constituted primarily for NO2. NOx production was observed within the first 50 cm of the snowpack during the sunlight season between February and August. Presence of NOx at larger depths was attributed to high speed wind and vertical transport processes. Production of NO correlated with the seasonal incoming radiation profile, while NO2 maximum was observed in April. These measurements constitute the larger data set of NOx within the firn and will improve the representation of processes driving snow photochemistry at Summit.

Seafloor to Summit: The Birth of Everest

This lecture, delivered at Montana Tech, documents the 2012 expedition to Mt. Everest in Nepal by Conard Anker and Dave Lageson from Bozeman, Montana. The trip commemorated the 50th anniversary of the first American assent in 1963. The climbers gathered rock samples on and near the summit and created a new educational outreach model to elementary school children.

MODELING DYNAMICS OF OZONE AND NITROGEN OXIDES AT SUMMIT, GREENLAND WITH A 1-D PROCESS-SCALE MODEL

This work presents a 1-D process scale model used to investigate the chemical dynamics and temporal variability of nitrogen oxides (NOx) and ozone (O3) within and above snowpack at Summit, Greenland for March-May 2009 and estimates surface exchange of NOx between the snowpack and surface layer in April-May 2009. The model assumes the surface of snowflakes have a Liquid Like Layer (LLL) where aqueous chemistry occurs and interacts with the interstitial air of the snowpack. Model parameters and initialization are physically and chemically representative of snowpack at Summit, Greenland and model results are compared to measurements of NOx and O3 collected by our group at Summit, Greenland from 2008-2010. The model paired with measurements confirmed the main hypothesis in literature that photolysis of nitrate on the surface of snowflakes is responsible for nitrogen dioxide (NO2) production in the top ~50 cm of the snowpack at solar noon for March – May time periods in 2009. Nighttime peaks of NO2 in the snowpack for April and May were reproduced with aqueous formation of peroxynitric acid (HNO4) in the top ~50 cm of the snowpack with subsequent mass transfer to the gas phase, decomposition to form NO2 at nighttime, and transportation of the NO2 to depths of 2 meters. Modeled production of HNO4 was hindered in March 2009 due to the low production of its precursor, hydroperoxy radical, resulting in underestimation of nighttime NO2 in the snowpack for March 2009. The aqueous reaction of O3 with formic acid was the major sync of O3 in the snowpack for March-May, 2009. Nitrogen monoxide (NO) production in the top ~50 cm of the snowpack is related to the photolysis of NO2, which underrepresents NO in May of 2009. Modeled surface exchange of NOx in April and May are on the order of 1011 molecules m-2 s-1. Removal of measured downward fluxes of NO and NO2 in measured fluxes resulted in agreement between measured NOx fluxes and modeled surface exchange in April and an order of magnitude deviation in May. Modeled transport of NOx above the snowpack in May shows an order of magnitude increase of NOx fluxes in the first 50 cm of the snowpack and is attributed to the production of NO2 during the day from the thermal decomposition and photolysis of peroxynitric acid with minor contributions of NO from HONO photolysis in the early morning.

Unmet needs of young interventional cardiologists: proceedings from the 2nd summit of the European association of percutaneous cardiovascular interventions

Every year, the EAPCI Board invites presidents and representatives of the interventional working groups affiliated to EAPCI to discuss issues and strategies surrounding the goals of education and advanced healthcare practices in interventional cardiology. In 2013, the 2nd EAPCI Summit, organised by the EAPCI Board in collaboration with the NIFYI committee, was entirely dedicated to discussing the unmet needs of the young generation of interventional cardiologists. In this article, we highlight a selection of the key points and proposed actions highlighted during the summit.
