The rights-based approach to social protection in Latin America: From rhetoric to practice

This paper aims to contribute to developing the normative framework for rights-based social protection systems and discusses lessons learned in some emblematic programmes implemented in Latin America which have sought to advance a rights approach. The paper emphasizes the added value of the rights-based approach and describes the normative content of the right to social security. It then describes the basic elements of a rights-based approach and examines how it is operationalized in the design, implementation and evaluation of landmark social protection programmes in the region. The paper seeks to demonstrate that, despite the large gap that still exists between the rhetoric of a human rights approach and its implementation in specific policies, there have been significant achievements in some countries in Latin America. It argues that some of the good practices in the region can serve as policy examples to follow elsewhere. The paper concludes with a number of public policy recommendations with a view to consolidating the rights perspective in social protection programmes.

Access to international capital markets: recent developments in Central America and the Caribbean

The objective of this report is to analyze the impact of recent global financial trends on the access to private external financing by Central American and Caribbean (CAC) economies, as well as their performance in international capital markets in recent years. The CAC economies, like many other countries in the world, were not immune to the negative consequences of the global economic and financial crisis of 2008. In fact, their openness, export driven growth and linkages to advanced economies, particularly to the U.S., as well as size, made them more vulnerable than other Latin American countries to the negative effects of the crisis. In addition, their recovery was hindered by their weak linkages to the larger emerging market countries that drove global growth in the post-crisis recovery. As China and other emerging market economies begin to slowdown, however, and the U.S. and other advanced economies show signs of a strengthening recovery, the linkages to advanced economies may once again become a source of strength.

This report was published with the goal of discussing, disseminating and using the results of this initiative in the formulation of national and regional strategies and have been presented at national and regional events with civil servants, representatives of non-governmental organizations, trade unions, the private sector, universities and research centers. The results have served as inputs in the training of national committees on climate change and negotiating teams, as well as in the preparation of the Regional Climate Change Strategy, several international financing projects and various national policies. The results have been presented in coordination with the Ministries of Environment at the last three Conferences of the Parties of the United Nations Framework Convention on Climate Change.

The cost of hunger: Social and economic impact of child undernutrition in Central America and the Dominican Republic

This document presents the results derived from the analyses of the cost of undernutrition in Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, Panama and the Dominican Republic. The study shows that not only are the effects reported valid for the countries of Central America and the Dominican Republic, but the resultant economic impact is also significant, representing between 1.7% and 11.4% of GDP. In this regard, productivity losses as a consequence of the higher death rate and the lower level of education account for 90% of the costs. Thus, in addition to the ethical imperative, eradicating undernutrition would yield benefits as well. Therefore, any programme that is effective in reducing the prevalence of this problem will have an impact on people's quality of life, and will also represent major savings for society. The greater the problem, the greater the challenge, but the greater the benefits as well, especially in terms of countries' production capacity.

Preserving Iron Gall Ink Objects in Collections in South and Central America and the Caribbean, Part 1: Assessing Preservation Needs of Ink-Corroded Materials

Most museums, libraries, and archives throughout the world have to deal with paper damaged by iron gall ink. For more than a decade international research has been devoted to the topic in an attempt to provide practical treatments for objects and formulate guidelines for the preservation of iron gall ink collections. A working group of conservators in South and Central America and the Caribbean have developed a program to disseminate research findings, collect data about the condition of iron gall ink collections in their countries and identify imminent training needs. The goal of this project is to combine the latest research with existing and acceptable conservation practices and share information about risk management, proper housing, examination and treatment of iron gall ink inscribed artefacts-at risk. Communications among colleagues were established to learn more about the current resources available in collections from various countries.

Craniometric diversity of the common vampire bat (Desmodus rotundus) in Central and South America

The common vampire bat, Desmodus rotundus Geoffroy, 1810, is a species with an extensive geographical distribution, occurring in a wide variety of habitats. A recent phylogeographical study using molecular markers described a scenario in which this species is formed by 5 distinct geographically circumscribed mitochondrial clacks. Here we studied the craniometric variation of the common vampire bat to assess the amount of subdivision within this species and to test for the possibility of distinct morphological patterns associated with geographical lineages. We used 16 measurements from 1,581 complete skulls of adult D. rotundus representing 226 localities in South America and Mesoamerica. The assessment of morphological diversity between groups was done by the estimation of minimum F-ST values. Overall, the results show that most of the within-species variation is a result of the size component. Both shape data and size data are correlated with geographic distances. Our results favor the origin of biological diversity as the outcome of genetic drift and stepping-stone pattern of gene flow instead of local adaptations to local environmental conditions. The F-ST analyses also support male-biased dispersal. The results give little evidence to support previous suggestions that the common vampire bat may be composed of 2 or more species.

Systematics of the Oswaldoi Complex (Anopheles, Nyssorhynchus) in South America

Abstract Background Effective malaria control relies on accurate identification of those Anopheles mosquitoes responsible for the transmission of Plasmodium parasites. Anopheles oswaldoi s.l. has been incriminated as a malaria vector in Colombia and some localities in Brazil, but not ubiquitously throughout its Neotropical range. This evidence together with variable morphological characters and genetic differences supports that An. oswaldoi s.l. compromises a species complex. The recent fully integrated redescription of An. oswaldoi s.s. provides a solid taxonomic foundation from which to molecularly determine other members of the complex. Methods DNA sequences of the Second Internal Transcribed Spacer (ITS2 - rDNA) (n = 192) and the barcoding region of the Cytochrome Oxidase I gene (COI - mtDNA) (n = 110) were generated from 255 specimens of An. oswaldoi s.l. from 33 localities: Brazil (8 localities, including the lectotype series of An. oswaldoi), Ecuador (4), Colombia (17), Trinidad and Tobago (1), and Peru (3). COI sequences were analyzed employing the Kimura-two-parameter model (K2P), Bayesian analysis (MrBayes), Mixed Yule-Coalescent model (MYC, for delimitation of clusters) and TCS genealogies. Results Separate and combined analysis of the COI and ITS2 data sets unequivocally supported four separate species: two previously determined (An. oswaldoi s.s. and An. oswaldoi B) and two newly designated species in the Oswaldoi Complex (An. oswaldoi A and An. sp. nr. konderi). The COI intra- and inter-specific genetic distances for the four taxa were non-overlapping, averaging 0.012 (0.007 to 0.020) and 0.052 (0.038 to 0.064), respectively. The concurring four clusters delineated by MrBayes and MYC, and four independent TCS networks, strongly confirmed their separate species status. In addition, An. konderi of Sallum should be regarded as unique with respect to the above. Despite initially being included as an outgroup taxon, this species falls well within the examined taxa, suggesting a combined analysis of these taxa would be most appropriate. Conclusions: Through novel data and retrospective comparison of available COI and ITS2 DNA sequences, evidence is shown to support the separate species status of An. oswaldoi s.s., An. oswaldoi A and An. oswaldoi B, and at least two species in the closely related An. konderi complex (An. sp. nr. konderi, An. konderi of Sallum). Although An. oswaldoi s.s. has never been implicated in malaria transmission, An. oswaldoi B is a confirmed vector and the new species An. oswaldoi A and An. sp. nr. konderi are circumstantially implicated, most likely acting as secondary vectors.

Transacciones, delegación o unilateralidad. Un análisis de los equilibrios de poder en las relaciones ejecutivo-legislativo durante los primeros gobiernos de Álvaro Uribe en Colombia y Carlos Saúl Menem en Argentina.

El presente trabajo analiza las relaciones entre poder ejecutivo y legislativo en los sistemas presidenciales, concentrándose específicamente en los casos de los primeros gobiernos de Álvaro Uribe Vélez en Colombia [2002-2006] y de Carlos Saúl Menem en Argentina [1989-1995]. Lo hace desde de una perspectiva analítica denominada neomadisoniana. Ubicada bajo el paraguas del neoinstitucionalismo, ésta utiliza como punto de partida el pensamiento de los padres fundadores de la democracia americana, particularmente el de James Madison, concentrándose en el estudio de como los arreglos institucionales constriñen el comportamiento de los actores a través del establecimiento de incentivos mediante los que se distribuyen distintos recursos de poder, proporcionando, además, una estructura estable, aunque no necesariamente eficiente, para la interacción humana. De este modo, el enfoque posee un particular interés por el análisis de la organización de los gobiernos, ya sea en términos de jerarquía o de transacciones entre actores instituciones [poderes ejecutivo y legislativo] que, de acuerdo al caso, gozan de distintos niveles de simetría y, consecuentemente, de capacidad de impactar sobre el proceso de toma de decisiones. Dentro de este marco, se intentarán identificar en el análisis de los casos patrones de regularidad y diferencia en relación a las características asumidas en el proceso de separación de poderes y el efecto que ejercen sobre él los poderes constitucionales y partidarios de los presidentes.

Miocene basin development and volcanism along a strike-slip to flat-slab subduction transition: Stratigraphy, geochemistry, and geochronology of the central Wrangell volcanic belt, Yakutat-North America collision zone

New geochronologic, geochemical, sedimentologic, and compositional data from the central Wrangell volcanic belt (WVB) document basin development and volcanism linked to subduction of overthickened oceanic crust to the northern Pacific plate margin. The Frederika Formation and overlying Wrangell Lavas comprise >3 km of sedimentary and volcanic strata exposed in the Wrangell Mountains of south-central Alaska (United States). Measured stratigraphic sections and lithofacies analyses document lithofacies associations that reflect deposition in alluvial-fluvial-lacustrine environments routinely influenced by volcanic eruptions. Expansion of intrabasinal volcanic centers prompted progradation of vent-proximal volcanic aprons across basinal environments. Coal deposits, lacustrine strata, and vertical juxtaposition of basinal to proximal lithofacies indicate active basin subsidence that is attributable to heat flow associated with intrabasinal volcanic centers and extension along intrabasinal normal faults. The orientation of intrabasinal normal faults is consistent with transtensional deformation along the Totschunda-Fairweather fault system. Paleocurrents, compositional provenance, and detrital geochronologic ages link sediment accumulation to erosion of active intrabasinal volcanoes and to a lesser extent Mesozoic igneous sources. Geochemical compositions of interbedded lavas are dominantly calc-alkaline, range from basaltic andesite to rhyolite in composition, and share geochemical characteristics with Pliocene-Quaternary phases of the western WVB linked to subduction-related magmatism. The U/Pb ages of tuffs and Ar-40/Ar-39 ages of lavas indicate that basin development and volcanism commenced by 12.5-11.0 Ma and persisted until at least ca. 5.3 Ma. Eastern sections yield older ages (12.5-9.3 Ma) than western sections (9.6-8.3 Ma). Samples from two western sections yield even younger ages of 5.3 Ma. Integration of new and published stratigraphic, geochronologic, and geochemical data from the entire WVB permits a comprehensive interpretation of basin development and volcanism within a regional tectonic context. We propose a model in which diachronous volcanism and transtensional basin development reflect progressive insertion of a thickened oceanic crustal slab of the Yakutat microplate into the arcuate continental margin of southern Alaska coeval with reported changes in plate motions. Oblique northwestward subduction of a thickened oceanic crustal slab during Oligocene to Middle Miocene time produced transtensional basins and volcanism along the eastern edge of the slab along the Duke River fault in Canada and subduction-related volcanism along the northern edge of the slab near the Yukon-Alaska border. Volcanism and basin development migrated progressively northwestward into eastern Alaska during Middle Miocene through Holocene time, concomitant with a northwestward shift in plate convergence direction and subduction collision of progressively thicker crust against the syntaxial plate margin.

Population amalgamation and genetic variation: observations on artificially agglomerated tribal populations of Central and South America.

The interpretation of data on genetic variation with regard to the relative roles of different evolutionary factors that produce and maintain genetic variation depends critically on our assumptions concerning effective population size and the level of migration between neighboring populations. In humans, recent population growth and movements of specific ethnic groups across wide geographic areas mean that any theory based on assumptions of constant population size and absence of substructure is generally untenable. We examine the effects of population subdivision on the pattern of protein genetic variation in a total sample drawn from an artificial agglomerate of 12 tribal populations of Central and South America, analyzing the pooled sample as though it were a single population. Several striking findings emerge. (1) Mean heterozygosity is not sensitive to agglomeration, but the number of different alleles (allele count) is inflated, relative to neutral mutation/drift/equilibrium expectation. (2) The inflation is most serious for rare alleles, especially those which originally occurred as tribally restricted "private" polymorphisms. (3) The degree of inflation is an increasing function of both the number of populations encompassed by the sample and of the genetic divergence among them. (4) Treating an agglomerated population as though it were a panmictic unit of long standing can lead to serious biases in estimates of mutation rates, selection pressures, and effective population sizes. Current DNA studies indicate the presence of numerous genetic variants in human populations. The findings and conclusions of this paper are all fully applicable to the study of genetic variation at the DNA level as well.
