Hamatospiculum flagellispiculosum (Nematoda: Diplotriaenidae) causing severe disease in a new host from Argentine Patagonia: Campephilus magellanicus (Aves: Picidae) Casalins, Laura; Ibáñez Molina, Mora; Wainer Gullo, Mariana; Brugni, Norma; Ortiz, Gala; Ojeda, Valeria Susana We describe pathological aspects of an infection caused by parasitic nematodes in skeletal muscles of a Magellanic woodpecker (Campephilus magellanicus), providing the first description of any disease findings in this species. A weakened female with locomotory dysfunction was rescued near Bariloche city (Argentine Patagonia), which soon died. At the necropsy, unexpected masses of tissue were located at three joints (legs and tail). A dissection of these masses exposed numerous nematodes in the musculature surrounding the joints that were identified as Hamatospiculum flagellispiculosum (Nematoda: Diplotriaenidae), a species that was not previously found in Piciformes (woodpeckers, toucans, and allies) of the Neotropical Region. In this report, we complement the original parasite description from 1952 with SEM images, and extend the species range about 2000 km southwards. Histopathological analysis (tissues sectioned 4–6 microns, stained with hematoxylin and eosin) of the affected tissues revealed parasitic myositis with muscle fibrosis. Severe muscle degeneration and necrosis, fibrous tissue replacing muscle tissue, chronic inflammation with widespread diffuse mononuclear infiltration, and parasitic content (adult roundworms, eggs, and eggs with first-stage larvae) were present in all samples. The multifocal nature of these lesions was consistent with the locomotory dysfunction exhibited by the bird. Both the immune response (mononuclear infiltration without eosinophils, which normally fight helminth colonization) and the clinical severity of this case (a lethal, multifocal macroparasite infection) are noteworthy. The expected immune response may have been suppressed through immunomodulation by the parasite, as observed for filarial parasites. Based on their demography and life history traits (i.e., long-lived picids that produce a single nestling every 1–2 years, and live in sparse populations), Magellanic Woodpeckers do not seem to be obvious hosts of an obligately killing parasite, and other (more regular) hosts should be expected to occur in the same region.

Ciudad(es) justa(s) y América Latina: aportes para un debate contemporáneo Jajamovich, Guillermo Paz Dentro del marco de las actuales estrategias económicas, la maximización de la renta viene imponiéndose como el principal motor de transformación espacial de las ciudades (Brenner, Marcuse y Mayer, 2009). Sin embargo, a contracorriente de esa tendencia, diversas ciudades, movimientos sociales, académicos y expertos pugnan por una orientación urbana y social distinta. En esa dirección, (re)emergen diversas articulaciones entre justicia y espacio que buscan promover ciudades, políticas y proyectos urbanos que sean más justos. Tal búsqueda supone una articulación entre conceptos, métodos académicos y herramientas de acción. En ese marco, este artículo retoma el concepto de just city y sus contestaciones como vía de entrada para dar cuenta de una serie de tensiones que recorren el debate urbano contemporáneo, contrapuntos entre miradas radicales y reformistas y discusiones respecto a con qué criterios y valores evaluar y proponer políticas urbanas que trasciendan el aludido mandato de la maximización de rentas en las ciudades. Asimismo, el artículo interroga las posibilidades de tal conceptualización como herramienta factible para el futuro de las ciudades en América Latina. En esa dirección, se proponen dos desplazamientos. En primer lugar, interrogar la plausibilidad de su extensión - y deslocalización - geográfica: en tanto concepto construido en y para el abordaje de políticas y proyectos de Estados Unidos y Europa, se reflexiona sobre sus potencialidades en América Latina, cuyas ciudades están signadas por desigualdades urbanas y sociales más acuciantes y capacidades estatales más acotadas a la hora de procurar territorios más justos. En segundo lugar, se propone un descentramiento de los objetos sobre los cuales ha sido aplicado: desde su foco en megaproyectos hacia su uso y aplicación a políticas urbanas más abarcativas.

Gradientes climáticos modelan la diversidad genética en especies leñosas de amplia distribución: el caso de Nothofagus pumilio en los Andes del sur; Climatic gradients model genetic diversity in widespread woody trees: the case of Nothofagus pumilio in the southern Andes Ignazi, Griselda; Mathiasen, Paula; Premoli Il'grande, Andrea Cecilia Los gradientes climáticos modelan la diversidad genética en especies leñosas de amplia distribución: este es el caso del Nothofagus ampliamente distribuido en los Andes del sur. Las especies de amplia distribución son un excelente modelo para analizar las respuestas adaptativas a distintos hábitats. Se estudió la variación genética en Nothofagus pumilio que habita bosques de montaña y altas latitudes, a lo largo de diferentes gradientes climáticos en Patagonia. Los resultados obtenidos muestran una fuerte relación entre el clima y los diferentes gradientes ambientales; y cómo éstos afectan a la variación genética de N. pumilio. Las variables bioclimáticas más influyentes están relacionadas a las precipitaciones de verano y temperaturas de invierno, siendo la tendencia general de mayor diversidad genética a mayores precipitaciones y temperaturas moderadas. Esto demuestra que la distribución espacial de la diversidad genética de esta especie no ocurre aleatoriamente, sino que los patrones de estructuración responden a modelos climáticos complejos. Comprender cómo la adaptación genética y/o los factores ambientales influyen sobre el rango de distribución de las especies resulta esencial para evaluar su supervivencia a largo plazo. Mientras que algunos genotipos pueden extinguirse localmente bajo distintos escenarios climáticos, otros podrían estar adaptados a condiciones climáticas particulares. Taxones de amplia distribución como N. pumilio han soportado cambios climáticos en el pasado, como los períodos glaciarios, a través de la adaptación y la plasticidad. Resaltamos la importancia de conservar la diversidad genética de las poblaciones, no solamente para la persistencia a largo plazo, sino también para amortiguar los impactos negativos del cambio climático global.; Climatic gradients model genetic diversity in widespread woody trees: the case of the widely distributed Nothofagus in the southern Andes. Widespread forest species are well suited to be the subject of studies combining adaptive responses to distinct habitats. We studied the genetic diversity of the wide-ranging Nothofagus pumilio that inhabits high-elevation and high-latitude forests, along different environmental gradients in Patagonia. The results of this study show a strong relationship between climate and the different environmental gradients; which in turn affect the genetic variation of N. pumilio. The most influential variables were related to summer precipitations and winter temperatures, where greater genetic diversity was associated to higher precipitations and milder temperatures. This demonstrates that the genetic diversity of this species is not randomly distributed in space, but it is structured according to complex climatic models. To understand how genetic adaptation and/or environmental aspects influence species’ distribution ranges is crucial to evaluate their potential for long term survival. While some genotypes may become locally extinct under different climatic settings, others might be locally adapted to particular climatic conditions, which may allow them to endure such changes. Widespread taxa as N. pumilio has undergone past environmental changes, such as those that occurred during glacial periods, through adaptation and plasticity. We highlight the importance of conserving genetic diversity of populations, not only to ensure the long-term persistence, but also to mitigate the negative impacts of global climate change.

The importance of trace minerals copper, manganese, selenium and zinc in bovine sperm-zona pellucida binding Anchordoquy, Juan Patricio; Anchordoquy, Juan Mateo; Lizarraga, Raúl Martín; Nikoloff, Noelia; Pascua, Ana Malen; Furnus, Cecilia Cristina Sperm-zona pellucida (ZP) binding is a necessary event for successful fertilization. The aim of this study was to determine the effect of trace minerals such as copper (Cu), manganese (Mn), selenium (Se) and zinc (Zn) on bovine spermatozoa binding to ZP. Sperm viability, functional membrane integrity, acrosomal status (AS), total antioxidant capacity (TAC) and sperm lipid peroxidation (LPO) were also evaluated. For the present study, in vitro fertilization (IVF) medium was supplemented with Cu (0.4 g/ml Cu), Mn (5 ng/ml Mn), Se (100 ng/ml Se), Zn (0.8 g/ml Zn), all minerals (Cu+Mn+Se+Zn), or tested without supplement (Control). Considerably more sperm bound to ZP when Cu, Se or Zn were added to the IVF medium, but there were no difference compared with the Control, Mn and Cu+Mn+Se+Zn groups. After 1 h of incubation, viability was increased by the addition of Cu, Mn and Se with respect to the Control but, after 2 h, viability was higher only with the addition of Mn to IVF medium. Functional membrane integrity improved in sperm treated with Cu. Acrosome integrity was higher in sperm treated with Zn after 1 h of incubation. LPO was significantly higher in sperm treated with Cu or Cu+Mn+Se+Zn. The mean TACs of sperm treated with Cu, Mn, Zn or Cu+Mn+Se+Zn were lower than in the Control. In conclusion, the results obtained in the present study determined that the presence of Cu, Se and Zn in the IVF medium increased the number of spermatozoa bound to the ZP, highlighting the importance of these minerals in the fertilization process.

Latin American ethnographic cinema: between exploration and denunciation Campo, Javier Alberto Between the decades of 1950 and 1970, a large number of ethnographic documentary films were made in Latin America. At a time when anthropological studies were being transformed and documentary filmmaking underwent a revolution because of new technologies, the films presented themselves as an original product of said cultural, scientific and cinematic changes. This article will study the most emblematic films and the filmmakers with the most extensive filmographies: Humberto Mauro (Brazil), Jorge Ruiz (Bolivia), Manuel Chambi (Peru), Sergio Bravo (Chile), Jorge Prelorán (Argentina), Margot Benacerraf (Venezuela), and Rolf Blomberg (Ecuador), among others. The aim of this article is to inquire into the filmographies and career trajectories of said directors in order to become acquainted with their vision on the popular cultures they documented spanning from the Andes to the coast and from the jungle to the countryside. This article thus intends to present this as the first appearance of a ‘common feeling’ among Latin American filmmakers.

Normal numbers with digit dependencies Christoph Aistleitne; Becher, Veronica Andrea; Olivier Carton We give metric theorems for the property of Borel normality for real numbers under the assumption of digit dependencies in their expansion in a given integer base. We quantify precisely how much digit dependence can be allowed such that, still, almost all real numbers are normal. Our theorem states that almost all real numbers are normal when at least slightly more than $log log n$ consecutive digits with indices starting at position $n$ are independent. As the main application, we consider the Toeplitz set $T_P$, which is the set of all sequences $a_1a_2 ldots $ of symbols from ${0, ldots, b-1}$ such that $a_n$ is equal to $a_{pn}$, for every $p$ in $P$ and $n=1,2,ldots$. Here~$b$ is an integer base and~$P$ is a finite set of prime numbers. We show that almost every real number whose base $b$ expansion is in~$T_P$ is normal to base~$b$. In the case when $P$ is the singleton set ${2}$ we prove that more is true: almost every real number whose base $b$ expansion is in $T_P$ is normal to all integer bases. We also consider the Toeplitz transform which maps the set of all sequences to the set $T_P$ and we characterize the normal sequences whose Toeplitz transform is normal as well.

Adding the temporal dimension to spatial patterns of payment for ecosystem services enrollment Núñez Regueiro, Mauricio Manuel; Fletcher, Robert J.; Pienaar, Elizabeth F.; Branch, Lyn Clarke; Volante, José Norberto; Rifai, Sami Payments for Ecosystem Services (PES) programs are increasingly emphasized to address challenges of conserving forests. However, concerns remain regarding the ability of PES programs to ensure long-term conservation of threatened lands. Evaluation of large-scale PES programs, including the spatial and temporal patterns of enrollment, is scarce, especially for programs that aim to protect forest from severe threats such as expansion of industrial agriculture. Using information on PES enrollment across 252,319 km2 in the Argentine Chaco, we examined both the duration for which lands are enrolled in PES and their suitability for agriculture. Specifically, we examined whether the PES program has resulted in adverse selection not only in space but also in time. We built spatially explicit generalized linear models using information on participants’ length of contract and the potential of their land for agricultural use. We found the PES program enrolled land in areas with high agricultural potential, but enrollment of these lands occurred for shorter time periods than lands with lower levels of threat from deforestation. Consequently, adverse selection occurred over time but not in space. Our work demonstrates the importance of evaluating both temporal and spatial dimensions of adverse selection in PES for informing policy.

Estudiantes en contextos de educación a distancia. Variables vinculadas con el logro académico; Students in distance education contexts. Variables linked to academic achievement Chiecher, Analía Claudia El artículo toma como punto de partida las altas cifras de abandono que caracterizan a la educación a distancia y, por el contrario, los bajos porcentajes de estudiantes que consiguen cursar trayectorias ajustadas a los tiempos que establece el plan de estudios. El objetivo del escrito se orienta a analizar perfiles de un grupo de estudiantes de primer año, de modalidad a distancia, cuyas trayectorias se ciñeron a la progresión temporal fijada por el plan de estudios. Se realizó un estudio no experimental y descriptivo en el cual participaron estudiantes de primer año de carreras de grado dictadas a distancia, quienes cumplían, además, la condición de haber regularizado todas las asignaturas previstas en el plan de estudios. Para la recolección de datos se administró un cuestionario de autoinforme, que recaba información sobre variables personales y contextuales con posible incidencia en las trayectorias académicas. Los resultados muestran que, entre las variables personales consideradas en el estudio, aquellas que parecen tener vinculación con trayectorias de logro son el nivel educativo de los padres, las metas de aprendizaje y las atribuciones causales internas y modificables. Asimismo, las variables contextuales percibidas como promotoras del logro se vincularon principalmente con la disponibilidad del profesor y su rapidez para responder consultas y ofrecer devoluciones de las actividades realizadas. La discusión propone líneas de acción que, sustentadas en los resultados del estudio, podrían contribuir a la promoción del logro estudiantil en la educación a distancia.

Hotspot of tadpole abnormality in suburban south-west Florida Anzaldua, Sharon Pratt; Goldberg, Francisco Javier A high concentration of Cuban treefrog (Osteopilus septentrionalis) tadpoles displaying morphological abnormalities was discovered in an untreated swimming pool in Bonita Springs, Florida. This find initiated a 4-year survey (2012-2015) of surrounding roadside drainage ditches that had been treated with insecticide for mosquito control. The study was extended to the populations of Ave Maria, Florida, and Everglades National Park. The core data set of 36,550 tadpoles from the swimming pool and ditches contained 25,136 abnormal tadpoles, an abnormality average of 68.8 %, well above the 5 % minimum definition for a hotspot. The frogs from Ave Maria and the Everglades National park were 0 % abnormal. The type of tadpole abnormality differed between the suburban treated roadside drainage ditches versus the untreated swimming pool, although the same abnormalities were found in both the suburban treated and untreated water. In the untreated swimming pool, 70.1 % of tadpoles displayed abnormalities such as bent tails, abnormal limbs, and disfigured or absent
mouthparts. Larvae in the untreated swimming pool metamorphosed en masse despite abnormalities. The high frequency of abnormal metamorph abnormalities found were: kyphosis, scoliosis, microcephaly, and forelimb abnormalities. In the treated roadside drainage ditches, Gosner stage 16-25 tadpoles could not undergo metamorphosis and experienced mass mortality. The abnormalities found at Gosner stage 16 of the embryo were in the head and body. Tadpoles at Gosner stages 19-25 failed to develop gills, were bloated, had growth retardation, and mouthpart abnormalities. The older Gosner stage 25-41 tadpole populations in the ditches showed bloating, lumps, emaciation, and growth retardation. A brief synopsis of O. septentrionalis treefrog biology is also given, including breeding congregations, average 8 hour time to hatching, and 19 days metamorphosis.

El archivo de Manuel Molina: continuidades y rupturas en la lingüística patagónica del siglo XX; Manuel Molina´s archive: continuities and breaks in Patagonian linguistics of the 20th century Dominguez, Verónica Soledad; Orden, María Emilia Hacia fines del siglo XIX desde la congregación salesiana se realizaron documentaciones lingüísticas sobre las lenguas de la Patagonia. Posteriormente, esta práctica misionera cayó en desuso debido a la modificación de la realidad lingüística de la zona y de los cambios en los objetivos de esta congregación católica. A mediados del siglo XX Molina concibió un proyecto de resurgimiento de la lingüística misionera, que implicó la puesta en valor de los aportes de los salesianos junto con la continuación de sus prácticas de registro. En esta búsqueda recuperó fuentes bibliográficas de anteriores salesianos, entabló encuentros con hablantes de distintas lenguas patagónicas. En este artículo nos proponemos analizar su metodología de trabajo, el aporte de los consultantes y la selección de materiales que finalmente prioriza para su edición. Nos centraremos en el cotejo de sus materiales de archivo, para dilucidar las diferencias entre la documentación existente en el gabinete y lo que efectivamente publica.; Toward the end of the 19th Century, linguistic registers on the Patagonian languages were made by the Salesian congregation. This missionary practice fell into disuse later, due to the modification of the linguistic reality of the zone and the change of this Catholic Congregation’s objectives. In the middle of the 20th Century, Molina conceived a project of resurgence of the missionary linguistic practices that implied the value of the Salesian contributions as well as the continuation of their registration practices. During this research, he recovered bibliographical sources and met with speakers of various Patagonian languages. This paper analyzes his work methodology, the native speakers’ contributions and the selection of published material. It is focused on the comparison of Molina’s records in order to elucidate the differences between the collected material and the published one.

Polyamine Colloids Cross‐Linked with Phosphate Ions: Towards Understanding the Solution Phase Behavior Herrera, Santiago Esteban; Agazzi, Maximiliano Luis; Cortez, María Lorena; Marmisollé, Waldemar Alejandro; Tagliazucchi, Mario Eugenio; Azzaroni, Omar Ionically crosslinked poly(allylamine)/phosphate (PAH/Pi) colloids consist of self‐assembled nanostructures stabilized by supramolecular interactions. Under physiological conditions, these interactions should be present at high ionic strength and only in a narrow pH window to be effective as drug delivery agents. In this work we study the effect of the pH and ionic strength in the chemical behaviour of inorganic phosphate (Pi), poly(allylamine hydrochloride) (PAH) and their mixture in aqueous solution (PAH−Pi). By combination of experimental measurements and a theoretical model, we demonstrate that the driving force that leads to the formation of colloids is the electrostatic pairing between the positively charged amino groups in PAH and negatively charged HPO42− ions. Increasing the ionic strength of the system by addition of KCl weakens the PAH−Pi interactions and narrows the pH stability window from 4 to 1.8 pH units. In addition, a fully reversible system was obtained in which the colloids assemble and disassemble by changing the pH between 6.8 and 7.1 at high ionic strength, making them suitable for use as pH‐responsive nanocarriers.

Dragonflies and damselflies (Odonata) from Córdoba and San Luis provinces, Argentina Márquez, Javier Andrés; Principe, Romina Elizabeth; Berejnoi, Diego E.; Rodríguez, José S.; Bedano, José Camilo; Molineri, Carlos Nineteen geographical records for species of Odonata in 2 provinces of Argentina are documented. We provided records for 9 newly recorded species for Córdoba: Lestes spatula Fraser, 1946, Andinagrion peterseni (Ris, 1908), Argentagrion ambiguum (Ris, 1904), Erythemis attala (Selys in Sagra, 1857), Erythemis plebeja (Burmeister, 1839), Erythrodiplax media Borror, 1942, Micrathyria longifasciata Calvert, 1909, Micrathyria hypodidyma Calvert, 1906, and Tramea cophysa Hagen, 1867. In San Luis, we provided records for 10 newly recorded species: Hetaerina rosea Selys, 1853, Acanthagrion lancea Selys, 1876, Ischnura fluviatilis Selys, 1876, Oxyagrion rubidium (Rambur, 1842), Castoraeschna decurvata Dunkle & Cook, 1984, Rhionaeschna pallipes (Fraser, 1947), Phyllocycla argentina (Hagenin Selys, 1878), Erythrodiplax corallina (Brauer, 1865), Perithemis mooma Kirby, 1889, and Planiplax erythropyga (Karsch, 1891). Among these records, we extend the geographic distribution of A. peterseni and R. pallipes, which areendemic to Argentina and recorded P. erythropyga for the first time in Chaco phytogeographic province

Application of quality indicators to data from the National Network of Congenital Anomalies of Argentina Groisman, Boris; Barbero, Pablo Miguel; Mastroiacovo, Pierpaolo; Botto, Lorenzo; Bidondo, Maria Paz; Liascovich, Rosa Background: In Argentina, birth defects are a leading cause of infant deaths. In 2009, the National Network for Congenital Anomalies of Argentina (RENAC) was established as a hospital-based surveillance system of major structural birth defects. To assess and enhance the system's data quality, we previously developed data quality indicators (DQI). Our aim was to evaluate quality indicators in RENAC. Methods: We applied the DQI presented in a related publication to the 2016 RENAC data. Results: Among the DQI of description, spina bifida coverage and talipes had the lowest results. Regarding prevalence of hypospadias, it was lower than the defined threshold. RENAC did not achieve the ascertainment threshold of a prevalence of 21.5 per 10,000 for critical congenital heart defects. There was a high ratio of spina bifida to anencephaly. Conclusions: DQI provide a focus for improving quality, making decisions, and advocating for interventions. Examples include advocating for newborn screening of critical congenital heart defects with pulse oximetry; developing training programs for clinicians to improve the detection of isolated hypospadias; and developing visual tools and checklists to improve the completeness and accuracy of case description for spina bifida, talipes, and other major malformations. After the interventions, it is important to track the impact by measuring again the DQI.

Why Should We Become Posthuman? The Beneficence Argument Questioned Vaccari, Andrés Why should we become posthuman? There is only one morally compelling answer to this question: because posthumanity will be a more beneficial state, better than present humanity. This is the Posthuman Beneficence Argument (PBA), the centerpiece of the liberal transhumanist defense of "directed evolution." In this article, I examine PBA and find it deficient on a number of lethal counts. My argument focuses on the writings of transhumanist philosopher Nick Bostrom, who has developed the most articulate defense of PBA and disclosed its metaethical framework. I begin by locating PBA in the context of wider transhumanist claims for the desirability of posthumanity. I identify two crucial components: (1) a model of deliberative rationality, requiring reasons to endorse claims; and (2) the reasons themselves (i.e., the greater beneficence that posthumanity represents). I examine these two conditions, in turn, specifying the claims that they ask us to accept. Following Bostrom, I argue that there is a need for a foundationalist approach that assures us of some universality in the process of valuation. This is required to appropriately ground the moral continuity and appeal to universality that PBA demands. I examine the reasons why this approach ultimately fails, leaving posthumanity as an unintelligible concept with no moral force. I conclude by identifying (and endorsing) a more mature approach to the debate on human enhancement, one that forfeits the grandiose but baseless claims too often found in transhumanist defenses of directed evolution. In short, posthumanity may be a good science fiction trope, but it has no normative force in the moral philosophy of human enhancement.

Protección de datos personales. Especial referencia al proyecto de reforma de la ley Argentina Nº 25.326; Personal data protection. Special reference to the reform project of the argentine law No 25,326 Juri, Yamila Eliana Los avances operados en el mundo de la tecnología como de las relacionesjurídicas, hacen necesaria una actualización en materia de protección de datos personales. En este sentido analizamos someramente los puntos principales del proyecto de reforma que en este momento se discute en el Congreso Nacional a fin de adecuar nuestra legislación argentina a los estándares internacionales en esta materia.; The advances made in the world of technology as well as legal relations require an update on the protection of personal data. In this sense, we briefly analyze the main points of the reform project that is being discussed at the National Congress in order to adapt our Argentine legislation to international standards in this matter.

La ingratitud, de Matilde Sánchez: identidad y viaje; Matilde Sánchez’s La ingratitud: identity and travel Conde de Boeck, José Agustín; Cohen, Elisa Beatriz Centrada en el autoexilio de una joven mujer argentina en Europa, lanovela La ingratitud de Matilde Sánchez construye todo un sistema de representaciónen torno al contacto con una comunidad lingüística diferente y, a suvez, extiende esta alteridad hacia las tensiones identitarias entre lo femenino ylo masculino, la relación padre e hija, la juventud y la vejez, la soledad y la convivencia,lo nacional y lo extranjero, todo lo cual da cuenta del complejo trasfondode la realidad política y social de Argentina y de los alcances ideológicos de laescritura como estrategia para reconstruir una identidad escindida. A través delrecurso de lo epistolar y del monólogo interior, la novela de Sánchez motorizauna problemática que será axial a lo largo de toda su escritura: la relación entrela experiencia subjetiva, la memoria y el discurso de la mujer como parte de unacomunidad lingüística determinada.; Focused in the auto-exile of a young Argentine woman in Europe, Matilde Sanchez’s novel La ingratitud builds a whole system of representation around the contact with a different linguistic community and, at the same time, it extends that otherness toward the idenitity tensions between feminine/mas- culine, father-daughter relationship, youth/eld, solitude/coexistence, national/ foreign. All this involves Argentine complex background of political and social reality as well as ideological literary writing power to rebuild a defragmented so- cial identity. Through literary resources as epistolary writing and stream of con- sciousness, Sánchez’s novel shows a problematic that will be essential through-out her entire work: relationship between subjective experience, memory and women discourse as part of a particular linguistic community.

Adopción internacional: legalmente permitida, fácticamente prohibida Feuillade, Milton César En materia de adopción es claro que el legislador realizó mejoras en los textos legales, pero conceptualmente no ha querido cambiar el sistema, al punto tal que en la sanción del Código Civil y Comercial se quitó la cooperación. Tampoco se avizora la voluntad de ratificar la Convención de la Haya de 1993 sobre Protección del Niño y a la Cooperación en materia de Adopción Internacional, sumado a que la norma que establece los cinco años de residencia en el país para los extranjeros la hace de difícil implementación. Respecto a los adoptantes residentes en el país, el sistema del RUAGA requeriría reformas para las adopciones internacionales. Desde este panorama, como dice el título de este trabajo, hoy la adopción internacional está legalmente permitida y fácticamente prohibida.

Paleogeographic reconstruction of the Tar – San Martín lacustrine system during late Pleistocene to early Holocene: Landscape availability and hunter-gatherer circulation (Santa Cruz, Argentina) Horta, Luis Rubén; Belardi, Juan Bautista; Georgieff, Sergio Miguel; Carballo Marina, Flavia Elena This paper presents the paleogeographic reconstructions of flooded areas of the Tar - San Martín lacustrine system during the late Pleistocene - Holocene. The dimensions of lacustrine and glaciolacustrine levels of this basin are higher than the current levels of the lakes. The organic matter of lake levels recorded on stratigraphic profiles was described, sampled and dated using AMS, while other paleobathymetric indicators were also identified (height of the fan-delta apex and paleo-coast levels). Deriving out of the reconstruction of flooded areas it was established that the lake system was formed before 28 ka ago and would have reached its maximum expansion around 12 ka ago. The first hunter-gatherer occupation of the basin (11 ka)corresponds to the period of initial contraction of the lake system and the composition of the current configuration of the coastlines. This scenario would have allowed the exploration of western areas and the gradual incorporation of the forest to the action range of hunter-gatherer populations. Similarly, the levels of lakes Tar and San Martín would not have hindered the movement of human populations through the steppe throughout the Holocene.
