Structural change, balance-of-payments constraint, and economic growth: evidence from the multisectoral Thirlwall`s law

This paper contributes to the literature on balance-of-payments constrained growth by investigating how structural change identified with changes in the sectoral composition of exports and imports affects the external constraint We test both the original and a multisectoral version of Thirlwall`s law for a sample of Latin American and Asian countries The original Thirlwall s law is found to hold for all sample countries except South Korea, whereas the multisectoral analogue holds for all of them As the sectoral composition of exports and imports is found to matter for growth we analyze the evolution of each country`s weighted trade income elasticities

Corruption and the size of government: causality tests for OECD and Latin American countries

The purpose of this article is to examine the causality between government size and corruption, and to verify if there is a different pattern of causality between developed Organization for Economic Co-operation and Development (OECD) countries (excluding Mexico) and developing countries (Latin American countries) during the period 1996 to 2003. Applying Granger and Huang`s (1997) methodology we find evidence that size of government Granger causes corruption in both samples. Since a larger government involvement in private markets today will be followed in future by a higher level of corruption a policy advice would be to enhance governance. The promotion of good governance helps to combat corruption given that it complements efforts to reduce corruption more directly, and it is strongly recommended by the International Monetary Fund, other multilateral institutions, and all worried with the negative impacts of corruption on economic activity.

Heterogeneity, saving-investment dynamics and capital mobility in Latin America

The purpose of this paper is to analyze the dynamics of national saving-investment relationship in order to determine the degree of capital mobility in 12 Latin American countries. The analytically relevant correlation is the short-term one, defined as that between changes in saving and investment. Of special interest is the speed at which variables return to the long run equilibrium relationship, which is interpreted as being negatively related to the degree of capital mobility. The long run correlation, in turn, captures the coefficient implied by the solvency constraint. We find that heterogeneity and cross-section dependence completely change the estimation of the long run coefficient. Besides we obtain a more precise short run coefficient estimate compared to the existent estimates in the literature. There is evidence of an intermediate degree of capital mobility, and the coefficients are extremely stable over time.

Microsatellite allele sequencing in population analyses of the South American cactophilic species Drosophila antonietae (Diptera: Drosophilidae)

Drosophila antonietae belongs to the Drosophila buzzatii cluster, a cactophilic group of species naturally endemic to South America. Morphological and genetic analyses indicate that its populations are the most homogenous in the cluster and that the diversity observed is mainly a result of variation within populations. Seven polymorphic microsatellite loci were described for this species and used in the present study to investigate the genetic diversity of natural populations of D. antonietae by both length and sequence variation. The study aimed to understand how homoplasy and null alleles affect inferences about the population history of this species and to obtain an accurate interpretation of population inferences where these loci could be applied. The results provide useful information on the interpretation of genetic data derived from the microsatellite loci described for D. antonietae and on evolutionary aspects of cactophilic Drosophila. Importantly, the results indicate that size homoplasy and null alleles do not represent significant problems for the population genetics analyses because the large amount of variability at microsatellite loci compensate the low frequency of these problems in the populations.

Molecular phylogeny of the freshwater prawn genus Macrobrachium (Decapoda, Palaemonidae), with emphasis on the relationships among selected American species

The genus Macrobrachium Bate, 1868 is one of the best examples of widespread crustacean genera distributed globally throughout tropical and subtropical waters. Previous investigators have noted the systematic complexity of the group, and have suggested rearrangements within the family Palaemonidae. Our phylogenetic analysis of new mitochondrial DNA sequences of 58 species of Macrobrachium distributed mainly in America support the hypothesis of monophyly of this genus, if Cryphiops Dana, 1852 is accepted as a generic synonym. We concluded that the independent evolution of different types of life cycle (abbreviated larval development-ALD and extended larval development-ELD) must have occurred more than once in the history of the group. Similarly, we also concluded that the current type species of the genus, Macrobrachium americanum Bate, 1868, should not be considered valid, as previously proposed. The synonymy of two members of the `olfersi` species complex (M. birai Lobao, Melo&Fernandes, 1986 and M. holthuisi Genofre&Lobao, 1978) with M. olfersi (Wiegmann, 1836) was confirmed. Similar results were found in comparing M. petronioi Melo, Lobao&Fernandes, 1986 and M. potiuna (Muller, 1880), in which the genetic divergence placed M. petronioi within the level of intraspecific variation of M. potiuna. The taxonomic status of the genus Cryphiops, as well as theories on the origin of Macrobrachium, is also called into question.

A comparative study of population traits between two South American populations of the striped-legged hermit crab Clibanarius vittatus

The striped-legged hermit Crab Clibanarius vittatus, with a geographical distribution covering a wide range Of latitudes in the western Atlantic, was selected for a comparative study on population features between two different areas of the Brazilian coast that are separated by approximately 3000 km. The two populations Were sampled concurrently for nine months. The populations in northern and southeastern Brazil showed different profiles in terms of size of specimens, sex ratio, and shell occupation. The observed plasticity of these life-cycle traits of C. vittatus in relation to local environmental conditions is discussed. (C) 2009 Elsevier Masson SAS. All rights reserved

Revision of the South American species of Hagenulopsis Ulmer and Askola Peters (Ephemeroptera: Leptophlebiidae) with description of six new species

The South American species of the genera Askola and Hagenulopsis are revised. Three new species of Askola from Brazil are described based on male imagos. Askola emmerichi sp. nov. and A. paprockii sp. nov. present spotted wings, but differ in general coloration and details of genitalia; Askola cipoensis sp. nov. is easily distinguished because the male eyes being widely separated on meson of head. Three new species of Hagenulopsis are also described: H. lipeo (from Argentina and Bolivia) and H. zunigae (from Colombia), both described from imagos and nymphs, can be recognized by details of coloration and male genitalia. H. esmeralda sp. nov. from Ecuador, described from imagos, shows a distinct male genitalia and translucent male abdomen. A key to species for the the male and female imagos of Askola and Hagenulopsis species is provided.

Education and the historiography of Ibero-American independence: elusive presences, many absences

This contribution analyses recent historiographical tendencies in research in the field of education at the time of the political emancipation of the former Spanish and Portuguese colonies in Latin America. The article briefly presents the complex educational scene in Latin America on the eve of the movements for independence. Due to the revolutionary character of the process of independence, it identifies educational history as one of the most significant absences in the historiography of independence. Notwithstanding, education has certainly been addressed by historians of education, mostly focusing on the colonial or postcolonial period, while largely neglecting the two decades after 1808. This indicates both the divide prevalent between historians of education and historians of independence and the rather nationalistic conceptual frame of existing scholarship.

A hispanical dimension of the luso-american revolution (1820-1823)

The Independence of Brazil was proclaimed in September 1822 after two years during which constituent deputies elected on both sides of the Atlantic and gathered in Lisbon endeavoured to achieve unification with the former Portuguese metropoli. Due to the failure of these attempts a Constituent Assembly settled in independent Brazil in July 1823. Those two parlamentary experiences - the first to take place in the Portuguese dominions - were strongly influenced by the decisions adopted in Cadiz (1810-1814), and in Madrid (1820-1823), and by the independentist processes developed at the time in Spanish America. This work aims at observing that influence on the decisions adopted in Lisbon and Rio de Janeiro vis-a-vis the autonomical reivindications of several Brazilian provinces.

Waves of Change Within Civil Society in Latin America: Mexico City and Sao Paulo

For the past half a century, Latin American scholars have been pointing toward the emergence of new social actors as agents of social and political democratization. The first wave of actors was characterized by the emergence of novel agents-mainly, new popular movements-of social transformation. At first, the second wave, epitomized by nongovernmental organizations (NGOs), was celebrated as the upsurge of a new civil society, but later on, it was the target of harsh criticism. The literature often portrays this development in Latin American civil society as a displacement trend of actors of the first wave by the second wave-""NGOization""-""and even denounces new civil society as rootless, depoliticized, and functional to retrenchment. Thus, supposedly, NGOization encumbers social change. The authors argue that NGOization diagnosis is a flawed depiction of change within civil society. Rather than NGOization related to the depoliticization and neoliberalization of civil society, in Mexico City and Sao Paulo, there has been modernization of organizational ecologies, changes in the functional status of civil society, and interestingly, specialization aimed at shaping public agenda. The authors argue that such specialization, instead of encumbering social change, brings about different repertoires of strategies and skills purposively developed for influencing policy and politics. Their argument relies on comparative systematic evidence. Through network analysis, they examine the organizational ecology of civil society in Mexico City and Sao Paulo.

Doing Courts Justice? Studying Judicial Politics in Latin America

The past decade has brought an unprecedented boom in the study of courts as political actors in Latin America. We examine the extraordinary diversity of academic research on judicial politics in the region, identifying the key questions, findings, and theoretical debates in the literature, highlighting important conceptual disjunctions, and critiquing the research methods scholars of judicial politics in Latin America have employed in their work. We close by suggesting new avenues of inquiry to help advance the collective effort to understand the roles courts play in Latin American politics.
