Competing interests7. ReferencesThe etiology of reptilian viral diseases can be attributed to a wide range of viruses occurring across different genera and families. Thirty to forty years ago, studies of viruses in reptiles focused mainly on the zoonotic potential of arboviruses in reptiles and much effort went into surveys and challenge trials of a range of reptiles with eastern and western equine encephalitis as well as Japanese encephalitis viruses [1-3]. In the past decade, outbreaks of infection with West Nile virus in human populations and in farmed alligators in the USA have seen the research emphasis placed on the issue of reptiles, particularly crocodiles and alligators, being susceptible to, and reservoirs for, this serious zoonotic disease [4-7]. Although there are many recognised reptilian viruses, the evidence for those being primary pathogens is relatively limited. Transmission studies establishing pathogenicity and cofactors are likewise scarce, possibly due to the relatively low commercial importance of reptiles, difficulties with the availability of animals and permits for statistically sound experiments, difficulties with housing of reptiles in an experimental setting or the inability to propagate some viruses in cell culture to sufficient titres for transmission studies. Viruses as causes of direct loss of threatened species, such as the chelonid fibropapilloma associated herpesvirus and ranaviruses in farmed and wild tortoises and turtles, have re-focused attention bac
Imaginarios regionales y circularidad en la planificación: el caso del TOAR
Intersecciones en antropolog?-a , 2006,
Abstract: the circular management model is characterized by planned actions and continuous evaluation by those involved. organizational culture, consisting of both practices and imaginaries shared between actors and agents, plays a key role. confronting the challenge of building a region with medium-sized cities, these imaginaries, which create their own local identities, cover any practice and social management in their heterogeneity as well as in their necessary conjunction of interests. for fifteen years there has been a vain attempt to create a partnership of territorial productive development among four cities in the province of buenos aires (tandil, olavarría, azul and rauch: toar). the challenge consists of creating a strategic plan that finally manifests this reality. the aim of this paper is to enrich the plan's management model, facilitating its organization, and to study the regional imaginaries. our hypothesis focuses on the methodological dimension of organizational management and establishes that the failures have been due to lineal and conductivist approaches, based on the theory of social homeostasis as is most strategic development. we propose a circular approach to management, based on the dialectic theory of conflict. in addition, we show how local imaginaries could be incorporated into regional planning.
Estado de conocimiento de los Ephemeroptera de Chile
Gayana (Concepción) , 2006, DOI: 10.4067/S0717-65382006000100009
Abstract: according to the actual knowledge of the ephemeroptera order in chile, it is concluded that there are 57 species included in 25 genera and 7 families. a 40% of the species are recognized through adults and larvae, 12% only for the larvae and 47% only for male and/or female adults. about its geographical distribution, the 56% of the species are endemics, the 33% are native to chile and argentina and 11% are of widespread distribution.
La proyección del enfoque etnográfico hacia la facilitación organizacional en procesos participativos de planificación urbana
Gravano, Ariel;
Horizontes Antropológicos , 2009, DOI: 10.1590/S0104-71832009000200004
Abstract: the objective of this work is to contribute to the organizational facilitation on participation processes of urban planning through the projection of an ethnographical approach. the problem at hand is the one that is portrayed in the social scene of real processes as well as the one that underlying in the wings of the methodological, theorical and ideological reflection. the point in common between both levels of analysis is that the actors involved in the scenes and the analysts themselves act according to a shared component that we place here as the core and objective of our proposal: the reflixibility, in terms of a cultural otherness built and objectifying that nurtures the practices towards the transformation as a circular and effective method of organizational achievements.
Análisis del discurso de una paciente: contraste entre el análisis en el nivel del relato y el análisis en el nivel de las palabras realizado con el diccionario computarizado
Subjetividad y procesos cognitivos , 2010,
Abstract: the objective of this study consists in contrasting the results obtained on two levels of analysis of the discourse of a patient: the level of narration and the level of the words. the sample used corresponds to the transcription of a first interview of an analytic session. the instrument with which the discourse analysis was tackled is the david liberman algorithm (dla). as regards the procedure: - on the level of narration, the material is split into 22 narrative sequences in which the drives and defenses are considered, the main ones as well as the complementary ones. regarding the defenses their state is also considered. apart from carrying out a study on a micro level of each sequence, the global results are evaluated, insofar as drives and defenses are concerned. concerning the first, statistical as well as logical prevalences are evaluated. - on the level of the words the computerized dla dictionary is used. this instrument is applied in its two modalities: automatic and interactive. in both cases the whole of the sample is considered. the results obtained correspond to the drives which are present in the patient′s discourse. in the last point, concerning the discussion and the conclusions, the results obtained on the two levels are compared. coincidences and divergences between them are analyzed.
Os usos sociais do dinheiro em circuitos filantrópicos: o caso das "publica??es de rua"
Wilkis, Ariel;
Mana , 2008, DOI: 10.1590/S0104-93132008000100008
Abstract: based on a case study of an organization responsible for publishing a magazine sold to ?homeless? people in buenos aires, i examine the social uses of money in philanthropic circles. turning to the polemic between money and gift at the centre of discussions in anthropology and sociology, i focus on two questions: a) the role of money in demarcating the limits between ?market transactions? and ?gift circulations?; b) the relation between money and morality. fieldwork involved an ethnographic study of the transactions between the sellers and buyers of this publication.
Un análisis del circuito de donación surgido a partir de las "publicaciones de la calle" en la ciudad de Buenos Aires
Av?? , 2006,
Abstract: in this article we develop an analysis of the donation circuit generated around "hecho en buenos aires" street magazine. in this sense we study the principles that allows this circulation of goods, from donators towards receptors. considering the characteristics of this kind of donations we analyse the "social scenes" in which both take part. far from thinking that this donations do not imply any kind of obligations, as a great part of the literature suggests, we state that obligations are present in order to encourage resources' circulation. our objective is to be able to interpret them as principles that allow us to explain this circuit. from this perspective we identify the triple economical, symbolic and moral circulation.
Pobreza y transformaciones económicas en Catamarca y Tucumán (1980-2002)
Poblaci?3n y sociedad , 2009,
Abstract: in the beginning of the 21st century catamarca and tucumán were showing important differences in social and economic level. while the first, with a more reduced and tradicional productive structure, had the less percentage of poor homes in the whole "norte grande argentino", tucumán suffered major levels of poverty, being its economy the most developed of the north of the country. having in mind that the poverty is intimately related to the economy, the present article is trying to analyze the characteristics of the poverty in tucumán and catamarca in 2001, and to investigate about the relations which existed between the differential levels of privation in both provinces and the transformations which suffered their respective productive structures in the last decades of the 20th century.

Sistemas Complejos y Comportamiento Humano
Polis (Santiago) , 2010, DOI: 10.4067/S0718-65682010000100020
Abstract: this article proposes an analysis about the inherent complexity of the dynamics of human groups, and among them, the interaction within a classroom. it shows how planning strict strategies or absolute improvisation can have terrible consequences for the educational process. precisely, in the middle ground between complete order and total disorder, maximum complexity could be found, which would allow high-level goals. finally, we propose the use of computer simulations to estimate the reach that an innovation in classroom interaction could produce.
