Big data and open data as sustainability tools: A working paper prepared by the Economic Commission for Latin America and the Caribbean

The two main forces affecting economic development are the ongoing technological revolution and the challenge of sustainability. Technological change is altering patterns of production, consumption and behaviour in societies; at the same time, it is becoming increasingly difficult to ensure the sustainability of these new patterns because of the constraints resulting from the negative externalities generated by economic growth and, in many cases, by technical progress itself. Reorienting innovation towards reducing or, if possible, reversing the effects of these externalities could create the conditions for synergies between the two processes. Views on the subject vary widely: while some maintain that these synergies can easily be created if growth follows an environmentally friendly model, summarized in the concept of green growth, others argue that production and consumption patterns are changing too slowly and that any technological fix will come too late. These considerations apply to hard technologies, essentially those used in production. The present document explores the opportunities being opened up by new ones, basically information and communication technologies, in terms of increasing the effectiveness (outcomes) and efficiency (relative costs) of soft technologies that can improve the way environmental issues are handled in business management and in public policy formulation and implementation.

Working paper on the eLAC 2018 Digital Agenda in consideration of Caribbean priorities for technology-supported development

eLAC 2018 will coordinate the implementation of programmes to support the use of information and communications technologies (ICTs) in achieving social and economic development goals for Latin America in the Caribbean during the 2015-2018 timeframe. The conceptual framework for this programme of work is described by the eLAC 2018 Digital Agenda, which is anticipated to be ratified by the fifth Ministerial Conference on the Information Society in Latin America and the Caribbean, to be held in August 2015 in Mexico City. There is a need for broader input from Caribbean countries to the eLAC 2018 Digital Agenda. Accordingly, this working paper reviews the document’s current draft, considering each of its objectives in the context of Caribbean development needs. Amendments are recommended to 12 of the objectives. Two additional objectives are also proposed, in the areas of regional coordination on universal service funds, and the establishment of a spatial data infrastructure to support the use of geographic information systems. Representatives of Caribbean countries are invited to use the contents of this document as an input to the development of their own proposed amendments for inclusion in the final version of the eLAC 2018 Digital Agenda.

Social Panorama of Latin America 2015. Briefing paper

The 2015 edition of Social Panorama of Latin America analyses poverty trends, as measured by ECLAC. It also examines changes in income distribution and in other aspects of inequality. With a view to contributing to the development of public policies to overcome poverty and socioeconomic inequality, this edition examines the latest trends in social spending and the challenges posed by demographic change, and provides in-depth analysis of persistent gaps in the labour market, of the challenges facing policies and programmes that foster inclusion in the labour market and production, and of social development institutions in Latin America.

Proveniência das rochas metassedimentares do Cinturão Araguaia com base em datações Pb-Pb em zircão e idades-modelo Sm-Nd

Este trabalho apresenta dados geocronológicos ²⁰⁷Pb/²⁰⁶Pb de grãos detríticos de zircão obtidos pelo método de evaporação de chumbo e idades-modelo Sm-Nd (T_DM) de rochas metassedimentares do Cinturão Araguaia, e discute as possíveis áreas-fonte dessas rochas, buscando investigar a história evolutiva deste cinturão no contexto da amalgamação do Gondwana. As datações em grãos detríticos de zircão de quartzitos da Formação Morro do Campo apontaram idades arqueanas (3,0-2,65 Ga) para o domínio norte (região de Xambioá) e, para o domínio sul (região de Paraíso do Tocantins), revelaram idades meso-neoproterozoicas (1,25-0,85 Ga) e, secundariamente, paleoproterozoicas (1,85-1,70 Ga), sugerindo a existência de áreas fontes distintas para os dois domínios. As idades-modelo Sm-Nd (T_DM) obtidas em metapelitos (ardósias, filitos, micaxistos) dos grupos Estrondo e Tocantins apresentaram distribuição bimodal com maior frequência de idades entre 2,1 e 1,4 Ga, com moda entre 1,7 e 1,6 Ga, e outras menos frequentes entre 2,7 e 2,4 Ga, sugerindo mistura de fontes de idade Paleoproterozoica (ou até Arqueana) com fontes mais jovens, provavelmente do Meso-Neoproterozoico. Os principais candidatos a fonte para as rochas do Cinturão Araguaia seriam os segmentos crustais situados a sudeste (Cráton São Francisco, Maciço de Goiás e Arco Magmático de Goiás). Toda a sucessão de rochas sedimentares da bacia oceânica Araguaia e rochas magmáticas associadas a estes segmentos foram transportados, posteriormente, em direção à margem oriental do Cráton Amazônico, durante a tectônica principal de estruturação do Cinturão Araguaia, resultante da amalgamação do supercontinente Gondwana.

Intraspecific variability of Holostylis reniformis: concentration of lignans, as determined by maceration and supercritical fluid extraction (SFE-CO2), as a function of plant provenance and plant parts

Maceration and supercritical fluid extraction were used to prepare extracts from parts of plants (Holostylis reniformis) collected in two different regions of Brazil. ¹H NMR, HPLC-DAD-ESI/MS, HPLC-DAD, GC-MS, and chemometric techniques were used to analyse lignans in the extracts and showed that yields of SFE-CO2 were less than or equal to those of hexane maceration extracts. These analyses, in conjunction with the concentrations of aliphatic hydrocarbons, fatty acids and their methyl and ethyl derivatives in the extracts, also allowed the chemical composition of parts and provenance of the plant to be differentiated.

A representação na Arquivística contemporânea

The arrangement and description of archival materials are the nuclear processes of Archival Science that share a common purpose: to represent the archival knowledge. This representation is fundamentally based on the application of the principle of provenance and on the concept of fonds. This paper aims to discuss de archival description facing the changes and ideas of an archival postmodern approach that proposes the concept of fonds and the principle of provenance as conceptual abstraction rather than a physical entity in the representation process. In that sense, it is presented here the theoretical perspectives of Canadian and Australian studies, discussing the theoretical basis of Modern Archival Science, facing the dynamic reality of contemporary record creation.

Position paper from the IBRA Symposium on Surgery of the Head - The 2nd International Symposium for Condylar Fracture Osteosynthesis, Marseille, France 2012

Background: This is a position paper from the 2nd International Bone Research Association (IBRA) Symposium for Condylar Fracture Osteosynthesis 2012 was held at Marseille, succeeding the first congress in Strasbourg, France, in 2007. The goal of this IBRA symposium and this paper was to evaluate current trends and potential changes of treatment strategies for mandibular condylar fractures, which remain controversial over the past decades.Methods: Using a cross-sectional study design, we enrolled the consensus based on the panel of experts and participants in the IBRA Symposium 2012. The outcomes of interest were the panel and electronic votes on management of condylar base, neck and head fractures, and panel votes on endoscopic and paediatric condylar fractures. Appropriate descriptive and univariate statistics were used.Results: The consensus derived from 14 experts and 41 participant surgeons, using 12 case scenarios and 27 statements. The experts and participants had similar decision on the treatment of condylar base, neck and head fractures, as well as similar opinion on complications of condylar fracture osteosynthesis. They had a parallel agreement on using open reduction with internal fixation (ORIF) as treatment of choice for condylar base and neck fractures in adults. Endoscopic approaches should be considered for selected cases, such as condylar base fractures with lateral displacement. There was also a growing tendency to perform ORIF in condylar head fractures. The experts also agreed to treat children (> 12 years old) in the same way as adults and to consider open reduction in severely displaced and dislocated fractures even in younger children. Nevertheless, non-surgical treatment should be the first choice for children <6 years of age. The decision to perform surgery in children was based on factors influencing facial growth, appropriate age for ORIF, and disagreement to use resorbable materials in children.Conclusions: The experts and participating surgeons had comparable opinion on management of condylar fractures and complications of ORIF. Compared to the first Condylar Fracture Symposium 2007 in Strasbourg, ORIF may now be considered as the gold standard for both condylar base and neck fractures with displacement and dislocation. Although ORIF in condylar head fractures in adults and condylar fractures in children with mixed dentition is highly recommended, but this recommendation requires further investigations.
