Concha Meléndez opened up a venue for the discussion of a Latin American identity in works of literature when she implied that the great Latin American novel would gestate in the cities, the space where the typical Latin American would achieve an ideal state of consciousness and intellectual capabilities. ^ Her point of view mirrored nineteenth-century debate on a Latin American identity. Similar to her viewpoint, intellectuals of this period viewed the cities and their inhabitants of European extraction, as the ideal spaces and people on which an identity could be defined. However, the present state of urban and rural areas in Latin America demonstrates that there is no such clear-cut division of city and countryside or of their inhabitants. The dynamics of movement, from rural to urban areas, of people of diverse ethnic, and socioeconomic backgrounds, make it difficult to uphold descriptors of space, race, or culture, as sole descriptors of an identity. ^ A study of five twentieth-century novels from North and South America, La muerte de Artemio Cruz (1962), Hasta no verte Jesús mío (1969), Los ríos profundos (1981), La casa de los espíritus (1982), and Los años con Laura Díaz (1999) reveal that the dynamism of movement, between countryside, and cities of peoples of distinct races and social backgrounds, hamper the definition of a collective identity in specific spaces. As characters move, they are constantly reconfiguring their identities and creating tensions and conflicts that intensify social, racial and economic divisions in society. This makes it difficult to ascribe permanent identity descriptors, much less define a collective identity. ^ However, as writers of fiction address the malaise in Latin American societies, they have unearthed descriptors such as history, economy, land, and movement that advance a collective definition of self in these societies. Additionally, female characters have been granted a new identity. The overwhelming evidence in this study points to ‘land’ as the prime factor in the identity dilemma and suggests that a definition will not be possible until the vast landless populace is granted a space they can call home. Only then, perhaps, will Meléndez novel surface. ^

In the early twentieth century, musicology was established as an academic discipline in the United States. Nonetheless, with the exception of Iberian medieval and Renaissance repertories, U.S. scholars largely overlooked the music of the Spanish- and Portuguese- speaking world. Why should this have been the case, especially in light of Spain’s strong historical presence in the United States? This autobiographical essay examines this question by tracing the career of an individual musicologist, the Hispanist musicologist Carol A. Hess. Evaluated here are disciplinary shifts in U.S. musicology —methodological, philosophical, and ideological— over the past thirty years. These transformations have combined to make this repertory a viable field of study today. Musicologists in the United States can now make their careers by specializing in Iberian and Latin American music, as well as the music of the Hispanic diaspora. They research topics ranging from the avant-garde composer Llorenç Barber to the rapper Nach Scratch or the popular bandleader Xavier Cugat and his U.S. audiences of the 1940s, while others also pursue the time-tested areas of medieval and Renaissance music. Iberian and Latin American music is regularly offered in postsecondary institutions while instructors now have a variety of textbooks and other pedagogical resources from which to choose. All add up to a disciplinary freedom that would have been unthinkable only a few decades ago.

Background Associations between aplastic anemia and numerous drugs, pesticides and chemicals have been reported. However, at least 50% of the etiology of aplastic anemia remains unexplained. Design and Methods This was a case-control, multicenter, multinational study, designed to identify risk factors for agranulocytosis and aplastic anemia. The cases were patients with diagnosis of aplastic anemia confirmed through biopsy or bone marrow aspiration, selected through an active search of clinical laboratories, hematology clinics and medical records. The controls did not have either aplastic anemia or chronic diseases. A total of 224 patients with aplastic anemia were included in the study, each case was paired with four controls, according to sex, age group, and hospital where the case was first seen. Information was collected on demographic data, medical history, laboratory tests, medications, and other potential risk factors prior to diagnosis. Results The incidence of aplastic anemia was 1.6 cases per million per year. Higher rates of benzene exposure (>= 30 exposures per year) were associated with a greater risk of aplastic anemia (odds ratio, OR: 4.2; 95% confidence interval, CI: 1.82-9.82). Individuals exposed to chloramphenicol in the previous year had an adjusted OR for aplastic anemia of 8.7 (CI: 0.87-87.93) and those exposed to azithromycin had an adjusted OR of 11.02 (CI 1.14-108.02). Conclusions The incidence of aplastic anemia in Latin America countries is low. Although the research study centers had a high coverage of health services, the underreporting of cases of aplastic anemia in selected regions can be discussed. Frequent exposure to benzene-based products increases the risk for aplastic anemia. Few associations with specific drugs were found, and it is likely that some of these were due to chance alone.

While it is true that Latin American republics had no rival on maximising revenues from custom collection during the belle époque, this paper shows that Latin American countries were also generous importers, only behind the larger commercial countries of Western Europe in terms of imports per capita. Latin American citizens were much more linked to international trade than citizens of most regions of the world. Their relation to the world economy was tighter both via their imports and their exports relative to their population and income levels. This paper comes to show that there is no contradiction between the high custom collection by the Latin American republics and their high level of interaction with the global economy in the pre-1914 belle époque, although large country differences can be observed when descending from the regional to the national level.

We have analyzed the spatial accuracy of European foreign trade statistics compared to Latin American. We have also included USA s data because of the importance of this country in Latin American trade. We have developed a method for mapping discrepancies between exporters and importers, trying to isolate systematic spatial deviations. Although our results don t allow a unique explanation, they present some interesting clues to the distribution channels in the Latin American Continent as well as some spatial deviations for statistics in individual countries. Connecting our results with the literature specialized in the accuracy of foreign trade statistics; we can revisit Morgernstern (1963) as well as Federico and Tena (1991). Morgernstern had had a really pessimistic view on the reliability of this statistic source, but his main alert was focused on the trade balances, not in gross export or import values. Federico and Tena (1991) have demonstrated howaccuracy increases by aggregation, geographical and of product at the same time. But they still have a pessimistic view with relation to distribution questions, remarking that perhaps it will be more accurate to use import sources in this latest case. We have stated that the data set coming from foreign trade statistics for a sample in 1925, being it exporters or importers, it s a valuable tool for geography of trade patterns, although in some specific cases it needs some spatial adjustments.

This paper proposes a nonparametric test in order to establish the level of accuracy of theforeign trade statistics of 17 Latin American countries when contrasted with the trade statistics of the main partners in 1925. The Wilcoxon Matched-Pairs Ranks test is used to determine whether the differences between the data registered by exporters and importers are meaningful, and if so, whether the differences are systematic in any direction. The paper tests for the reliability of the data registered for two homogeneous products, petroleum and coal, both in volume and value. The conclusion of the several exercises performed is that we cannot accept the existence of statistically significant differences between the data provided by the exporters and the registered by the importing countries in most cases. The qualitative historiography of Latin American describes its foreign trade statistics as mostly unusable. Our quantitative results contest this view.

Background/Aims: The epidemiology of Chagas disease, until recently confined to areas of continental Latin America, has undergone considerable changes in recent decades due to migration to other parts of the world, including Spain. We studied the prevalence of Chagas disease in Latin American patients treated at a health center in Barcelona and evaluated its clinical phase. We make some recommendations for screening for the disease. Methodology/Principal Findings: We performed an observational, cross-sectional prevalence study by means of an immunochromatographic test screening of all continental Latin American patients over the age of 14 years visiting the health centre from October 2007 to October 2009. The diagnosis was confirmed by serological methods: conventional in-house ELISA (cELISA), a commercial kit (rELISA) and ELISA using T cruzi lysate (Ortho-Clinical Diagnostics) (oELISA). Of 766 patients studied, 22 were diagnosed with T. cruzi infection, showing a prevalence of 2.87% (95% CI, 1.6-4.12%). Of the infected patients, 45.45% men and 54.55% women, 21 were from Bolivia, showing a prevalence in the Bolivian subgroup (n = 127) of 16.53% (95% CI, 9.6-23.39%). All the infected patients were in a chronic phase of Chagas disease: 81% with the indeterminate form, 9.5% with the cardiac form and 9.5% with the cardiodigestive form. All patients infected with T. cruzi had heard of Chagas disease in their country of origin, 82% knew someone affected, and 77% had a significant history of living in adobe houses in rural areas. Conclusions: We found a high prevalence of T. cruzi infection in immigrants from Bolivia. Detection of T. cruzi¿infected persons by screening programs in non-endemic countries would control non-vectorial transmission and would benefit the persons affected, public health and national health systems.

The historiographical paper presented is about the students’ activism and participation in the Latin American psychology. This aims are: 1) to provide a brief historic overview of the Latin American psychology; 2) to review on the students’ participation in the Latin American psychology; 3) to raise students’ future perspectives for the Latin American psychology. It is recognized that there is an extensive past of Latin American psychology and an emerging historiographical work that re fl ects that past.However, there are several historiographical gaps not covered yet by the investigations in the region. In this context, this paper wants to contribute to the study of the students’ activism and participation in the Latin American psychology construction. The historical perspective is supported by the renewed historiographical conception called instant history” which focuses on ancient and recent history at the same time. Indirect sources were used: articles, monographs and compiled editions.
