Bioarqueología y cronología del sitio Negro Muerto 2 (Noreste de Patagonia)
SERNA,ALEJANDRO; PRATES,LUCIANO;
Magallania (Punta Arenas) , 2012, DOI: 10.4067/S0718-22442012000200011
Abstract: in this paper we present the first results for the analysis of human remains recovered at the negro muerto 2 (nm2) site, located in the south sector of the negro river’s middle basin (río negro province). during the rescue activities done at the site, four individuals had been recovered: individuals 1 and 2 were part of a double burial (the latter suffered a disarticulation at the level of the skull, which was relocated next to the first one); while individuals 3 and 4 were probably simple burials, although their high degree of disarticulation would not allow us to confrm this. three radiocarbon dates were obtained for this site between 2,000 and 1,500 years bp. the skull of the individual 2, dated in 1,586 ± 47 years bp, presents a tabular oblique cranial deformation; in this case the date obtained is less than the expected for such morphology.

Abstract: En este trabajo se presentan los primeros resultados del estudio de los restos humanos recuperados en el sitio Negro Muerto 2 (NM2), ubicado en el sector sur de la cuenca media del río Negro (provincia de Río Negro). Durante las actividades de rescate efectuadas en el sitio se recuperaron cuatro individuos: los individuos 1 y 2 formaban parte de un entierro doble (el último sufrió una desarticulación al nivel del cráneo, el cual se dispuso y enterró junto con el primero); y los individuos 3 y 4, probablemente fueron entierros simples aunque su alto grado de desarticulación no permite confirmarlo. Para el sitio se obtuvieron tres fechados radiocarbónicos de entre ca. 2.000 y 1.500 a os AP. El cráneo del individuo 2, fechado en 1.586 ± 47 a os A P, presenta una deformación artificial del tipo tabular oblicua; en este caso la edad obtenida es menor que la esperada para dicha morfología.

SITIO LOMA DE LOS MUERTOS: MúLTIPLES OCUPACIONES SOBRE UN MéDANO DEL ESTE DE NORPATAGONIA (ARGENTINA)
PRATES,LUCIANO; DI PRADO,VIOLETA; MANGE,EMILIANO; SERNA,ALEJANDRO;
Magallania (Punta Arenas) , 2010, DOI: 10.4067/S0718-22442010000100010
Abstract: in this article the results of the analysis of the archaeological record of loma de los muertos site (general conesa district, río negro province, argentine) is presented. in this site, domestic and two inhumatory activities were carried out, including human burials and, at least, one extint carnivore (dusicyon avus). three radiocarbon dates were obtained from the human burials and one for the canid remains, which locate the site in a time span between ca. 3.000 and 2.000 years bp. as a complement, the surface domestic materials related to the camp site were dated in ca. 500 years bp. materials for lithic artefacts were obtained from both primary (sandstone for ground stone tools) and secondary sources (volcanic cobbles for knapped tools). archaeofauna remain analysis shows several animals were exploited, such as mammals (guanaco and pampean deer), birds (?andú -sudamerican ostrich-), fishes and freshwater molluscs, all available nearby the site. pottery remains studies allowed reconstructing a complete vessel which was probably used in a domestic context. there are no evidences to prove chronological association between inhumatory and domestic activities at the site.
SITIO LOMA DE LOS MUERTOS: MúLTIPLES OCUPACIONES SOBRE UN MéDANO DEL ESTE DE NORPATAGONIA (ARGENTINA) LOMA DE LOS MUERTOS SITE: MULTIPLE OCCUPATIONS ON A SAND DUNE IN EAST NORPATAGONIA (ARGENTINA)

Abstract: En este trabajo se presentan los resultados del estudio del contexto arqueológico del sitio Loma de los Muertos (departamento de General Conesa, provincia de Río Negro, Argentina). En el sitio se llevaron a cabo actividades múltiples asociadas a un campamento residencial y se realizaron entierros humanos y de, al menos, un cánido extinto (Dusicyon avus). Se obtuvieron tres fechados para los entierros humanos y uno para los restos del carnívoro, que los ubican entre ca. 3.000 y 2.000 a os AP. Complementariamente, los materiales de superficie asociados al campamento fueron fechados en ca. 500 a os AP. Sobre la base de esta información, fueron inferidos al menos cuatro episodios diferentes de ocupación. La mayor parte de las materias primas líticas utilizadas y reducidas en el sitio se obtuvieron de fuentes locales de aprovisionamiento. Con ellas se fabricaron instrumentos de filo (principalmente raspadores) y de superficies activas (sobre todo de molienda). Se explotaron varias clases de fauna, como mamíferos (guanaco y venado de las pampas); aves ( andú); peces y moluscos de agua dulce; todos disponibles en proximidades del sitio. El estudio de los restos de alfarería permitió reconstruir el perfil de un recipiente que fue utilizado posiblemente para el procesamiento de alimentos sobre el fuego. Las evidencias disponibles no prueban la contemporaneidad de los entierros y las actividades de campamento. In this article the results of the analysis of the archaeological record of Loma de los Muertos site (General Conesa district, Río Negro province, Argentine) is presented. In this site, domestic and two inhumatory activities were carried out, including human burials and, at least, one extint carnivore (Dusicyon avus). Three radiocarbon dates were obtained from the human burials and one for the canid remains, which locate the site in a time span between ca. 3.000 and 2.000 years BP. As a complement, the surface domestic materials related to the camp site were dated in ca. 500 years BP. Materials for lithic artefacts were obtained from both primary (sandstone for ground stone tools) and secondary sources (volcanic cobbles for knapped tools). Archaeofauna remain analysis shows several animals were exploited, such as mammals (guanaco and pampean deer), birds ( andú -sudamerican ostrich-), fishes and freshwater molluscs, all available nearby the site. Pottery remains studies allowed reconstructing a complete vessel which was probably used in a domestic context. There are no evidences to prove chronological association between inhumatory and domestic activities a
Colonization and Collapse

Mathematics , 2015,
Abstract: Many species live in colonies that thrive for a while and then collapse. Upon collapse very few individuals survive. The survivors start new colonies at other sites that thrive until they collapse, and so on. We introduce a spatial stochastic process on graphs for modeling such population dynamic. We obtain conditions for the population to get extinct or to survive.
Le jugement comme pratique sociale : une réflexion sur la justice pénale brésilienne
Fernanda Prates
Champ Pénal , 2011, DOI: 10.4000/champpenal.8171
Abstract: Cet article propose d’approfondir l’analyse de la prise de décision judiciaire. Après avoir présenté une synthèse de l’approche traditionnelle de la prise de décision, on cherche à l’analyser à partir d’un regard sociologique. Elle est ainsi présentée comme (1) activité collaborative, (2) activité interactionnelle et (3) activité subjective. En examinant ces dimensions, inhérentes au processus décisionnel, le sens de la prise de décision comme pratique sociale est alors dégagé. Les données proviennent de notre recherche doctorale, au cours de laquelle nous avons eu l'occasion d’assister à 230 audiences sur une période de six mois au Palais de Justice de la ville de Rio de Janeiro (Brésil), et de réaliser des entretiens auprès de 23 juges pénaux. This paper intends to improve the analysis of judicial decision-making. After presenting a synthesis of the traditional approach of decision-making, I will seek to analyze it from a sociological point of view. It will be thus presented as a 1. collaborative activity, 2. interactive activity and 3. subjective activity. By examining these dimensions, the sense of decision-making process as a social practical will emerge. The data presented comes from our six-month fieldwork among penal judges in Brazil (Rio de Janeiro), when we had the opportunity to observe 230 criminal trials and interview 23 penal judges.

Arqueología de la cuenca media del río Negro (provincia de Río Negro): Una primera aproximación
Prates,Luciano R.;
Intersecciones en antropolog?-a , 2004,
Abstract: in this article the results of a systematic archaeological survey carried out in a restricted area of the río negro valley, río negro province, are presented, as well as the general characteristics of the archaeological record. the area lies at the place known as boca de la travesía, located 130 kilometers from the mouth of the river. given the scant archaeological information available related to the valley, a summary of previous research in east norpatagonia is included. based on the analysis of the material recovered, aspects linked to the origin and exploitation of lithic raw materials and the activities carried out at the sites are discussed. the characteristics of the artifactual assemblage and the diversity of faunal remains, among which freshwater bivalves can be found, provide evidence for activities related to the exploitation of a variety of resources. furthermore, taking into consideration the environmental characteristics and the areas in which discoveries were made, we discuss aspects related to the visibility of the archaeological record and the possible influence of certain natural site formation processes.
El uso de moluscos de agua dulce (Diplodon chilensis patagonicus) en el sitio Angostura 1 (Departamento de General Conesa, Río Negro)

Intersecciones en antropolog?-a , 2007,
Abstract: this note presents the results of an analysis of freshwater mollusk shells (diplodon chilensis patagonicus) recovered from the lower cultural component of the angostura 1 archaeological site (general conesa district, rio negro province, argentina). primarily, morphological features of this assemblage were analyzed, including: laterality, size, state of fracture, and the presence of periostracum. secondarily, burning evidence and spatial relationships were considered. site formation processes linked to human activity are discussed in light of these results and the contextual information from the site, i.e., mollusk shells associated with other archaeological remains (lithics, pottery, bones, and organic remains). it is proposed that the presence of freshwater mollusk shells in angostura 1 site is linked to human activity.
Símbolo do cora??o
Prates, Paulo R.;
História, Ciências, Saúde-Manguinhos , 2005, DOI: 10.1590/S0104-59702005000300020
Abstract: man created symbols because he needed to express his religion or visual art through objects or shapes. much before the heart's role in pumping blood was discovered, the organ was seen as the center of life, of courage, and of reason. it is the most universal of symbols. historians have always been curious as to how and whence this representation appeared, since it has little to do with the anatomical organ. for some, the origin lies in the heart's resemblance to an ivy leaf, which in ancient times was a symbol of immortality and power. the article explores the curious origin of this symbol and the reason it came into being.
