Argentine Republic Temporal distribution Results: In the 5 years period, 1 295 confirmed leishmaniasis cases were reported in the Geographical distribution Argentine Republic. One thousand twenty-eight (1 028) cases corresponded to cutaneous leishmaniasis (87.10%), being the most common type of leishmaniasis. Mucocutaneous leishmaniasis was in the second place in the country with 115 cases reported, mostly in the Northwest and Northeast regions. A total of 52 individuals with visceral leishmaniasis were identified and Misiones Province was the most affected. Conclusions: It is important to analyze the temporal and geographical distribution of leishmaniasis in order to provide an adequate management and surveillance. 1.

    Upper Paraná Atlantic Forest Program

    Upper Paraná Atlantic Forest Program The Upper Paraná Atlantic Forest – locally called Selva Misionera or Paranaense - is one of the world’s most biodiverse subtropical ecoregions. Spread across three countries – Argentina, Brazil and Paraguay – these forests are one of the planet’s most threatened areas as a result of past and present deforestation. Over the last decade, Fundación Vida Silvestre Argentina (FVSA), WWF’s associate organization, has been working towards the conservation of the forests of the Misiones Province. These forests –located in northeastern Argentina- are one of the largest forest blocks that still remains, and one of the few that still houses a jaguar population. From the heart of the jungle, FVSA-WWF’s office in Puerto Iguazú, just a few kilometers away from the impressive scenario offered by the Iguazú Falls, promotes conservation and sustainable development actions. Some of these undertakings are the Misiones Green Corridor and the Biodiversity Vision, a planning tool for the ecoregion. The Upper Paraná Atlantic Forest (UPAF) covers The Misiones Green Corridor was singled out in most part of the Misiones Province in northeastern the Biodiversity Vision as the most important area Argentina, and expands through the south of where to focus local actions with regional impact.

Earlier indices developed for Argentina (Velázquez, 2008; 2010a) provided basically two dimensions: a) socio-economic and b) environmental. Socio-economic dimension embraces such indicators as education, health and housing, while environmental one considers three aspects: nature-based recreational resources, socially constructed recreational resources and environmental problems.

ABSTRACT The final larval stadium of Mecistogaster amalia is described and illustrated for the first time based on one female collected in a tree hole in Misiones province, Argen­ tina, and compared with all known larvae of related genera. Larval morphology of Pseudostigmatidae is briefly discussed. INTRODUCTION Pseudostigmatidae include 17 species in five neotropical genera, i.e. Anomisma McLachlan, 1877, Mecistogaster Rambur, 1842, Megaloprepus Rambur, 1842, Microstigma Rambur, 1842, and Pseudostigma Selys, 1860. This family includes the longest species in the order Odonata, all of which as far as known breed exclu­ sively in phytotelmata as does its East African sister group Coryphagrion grandis Morton, 1924 (Corbet 1999: 145; Clausnitzer & Lindeboom 2002; Fincke 2005; Groeneveld et al. 2007).

ABSTRACT In order to strengthen their economic positions, developing nations like Argentina have produced laws aimed at salient informal manifestations. Argentina’s 2005 law “Patria Grande” sought to answer public outcry after a deadly fire exposed the inhumane conditions of illegal textile workers. What is the relationship between public policy and informality, and what legal, economic, and social characteristics identify the informal economy generally, and in Argentina specifically? What is the historical foundation of Argentine informality, and how has it behaved in the 21st century? Finally, how did Patria Grande develop, and what lessons can we learn from its results? By taking a public policy approach to informality, this study unravels the current characteristics and the historical roots of Argentina’s institution of informality. Three empirically recognized factors of informality are applied in a MIMC model and discussed with regard to Argentina’s history and present condition. These indicators support that, since the 2001-2 crisis, the Argentine informal economy appears to be shrinking, but at a decreasing rate.

    Portuguese Or Portuñol? Language Contact in Misiones, Argentina

    Journal of Linguistic Geography (2017) 4,47–64. © Cambridge University Press 2017 ORIGINAL RESEARCH doi:10.1017/jlg.2016.12 Portuguese or Portuñol? Language contact in Misiones, Argentina John M. Lipski* The Pennsylvania State University In the extreme northeastern Argentine province of Misiones, vernacular Portuguese is the primary language of many rural communities, in bilingual contact with Spanish. The present study examines data from Misiones Portuguese and Spanish for evidence of morphosyntactic convergence in the absence of formal schooling in either language or sociolinguistic pressures to produce canonical varieties. Data from a corpus of vernacular Misiones Portuguese and the results of a speeded translation task reveal that even in this sociolinguistically permissive environment bilingual speakers maintain distinct morphosyntactic systems for Portuguese and Spanish (exemplified by nominal plural marking and first-person plural verbal inflection). The data also suggest that bilingual contact alone does not yield the degree of convergence required for the hybrid Portuguese-Spanish morphosyntaxis that has been reported, for example, in northern Uruguay. 1.

    Argentine National Identity and the War on Terror: Civilization, Barbarism, and Rumors of Islamic Radicalism in the Tri-Border A

    God is everywhere, but his office is in Buenos Aires. – Argentine Proverb ii ABSTRACT This thesis explores the nuanced relationship between Argentine national identity, or argentinidad, and the introduction of the War on Terror into the Tri-Border Area of South America. An isolated and ill-governed frontier zone shared by Argentina, Brazil, and Paraguay, the Tri-Border Area was commonly associated with various illegal economic activities for decades. However, following the September 11, 2001 attacks, the American government and media falsely vilified the region as a haven for terrorist groups. While Paraguay and Brazil were guarded in their responses to the negative discourse regarding the Tri-Border Area, Argentina readily accepted the possibility of terrorists on its northeastern frontier. The project explains this behavior through examination of the influence of national identity on foreign policy. First utilizing the method of causal process tracing, the analysis demonstrates that Argentine national identity predominately accounts for Buenos Aires and the surrounding pampas. Consequently, this development created “negative spaces” within formal state boundaries. These areas are perceived as located outside of the sovereign and civilized state. Discourse analysis exhibits that the Tri-Border Area has traditionally been characterized as one such uncivilized space. Finally, reuse of discourse analysis reveals that American antiterrorism dialogue was particularly compatible with historical portrayal of the region. Therefore, Argentine

Abstract Tribe Hydropsini (Serpentes: Dipsadidae: Xenodontinae) consists of three genera of aquatic snakes, Helicops, Hydrops, and Pseudoeryx, in which cartilaginous cranial features have been poorly studied. We here describe the nasal cartilages, hyobranchial apparatus, larynx, and glottal tubes in four representative Hydropsini species, compare them with species from other Dipsadidae tribes, and discuss our results in the context of the adaptation to the aquatic and fossorial habit. The studied species possess two nasal features that deviate from the pattern of nasal cartilages known in other aletinophidian and caenophidian snakes: (1) a cartilaginous connection between the lamina transversalis anterior and the concha of the Jacobson´s organ, and (2) a small rostral projection of the planum anteorbitale, which probably represents a reduced anterior maxillary process. Two putative synapomorphic features may be supporting the monophyly of Hydropsini: (1) a short inferior median eminence of the cricoid cartilage, and (2) a large processus entoglossus of the hyobranchial apparatus.
