Una forma de pescar recuerdos: Literatura y memoria ampliada en Nos espera el mar de Santiago Garat
Full text linkDrawing on the theoretical and methodological frameworks of memory studies, as well as the perspective of the sociology of literature, this article analyzes the short story collection Nos espera el mar by Santiago Garat, a journalist from Rosario (Santa Fe, Argentina) and son of Eduardo Garat, who disappeared in 1978. Published by a cooperative, we believe this work offers unique insights into how the younger generation continues to process the recent past, following the Kirchnerist period’s impact on the recovery of 1970s historical memory. Among these insights, we focus on the representation of the popular class and, in particular, on the institutional violence inflicted upon its youth in a democratic context, interpreted as a continuation of state violence during the dictatorship. We examine how some of these short stories activate dialogues between the past and the present, and the role that fiction plays in generating such dialogue.A partir de las claves teórico-metodológicas de los estudios sobre memoria, así como de la perspectiva de la sociología de la literatura, en este artículo analizamos el libro de cuentos Nos espera el mar de Santiago Garat, periodista de Rosario (Santa Fe, Argentina), hijo de Eduardo Garat, desaparecido en 1978. Editada por una cooperativa, consideramos que esta producción ofrece elementos singulares para pensar los modos en que la generación de los hijos continúa elaborando el pasado reciente, luego de lo que significó el período kirchnerista en términos de recuperación de la memoria setentista. Entre ellos, nos detenemos en la representación de las clases populares y especialmente en la violencia institucional sobre sus jóvenes en democracia, leída como continuación de la violencia estatal en dictadura. De este modo, nos detenemos en las maneras en que algunos de estos relatos breves activan diálogos entre el pasado y el presente, así como el rol que asume la escritura de ficción para generarlo
Ressonância de gênero no ritmo da poesia argentina recente
No full textThis work sets out to critically examine the voices that emerge in a series of poems written by Tamara Domenech, Marina Mariasch and Fernanda Laguna, taking as its starting point the hypothesis that the rhythm of these poems enables the reading of novel areas of their works that are not thematically marked by gender, but which find in their vocality a dimension capable of obscuring the language of the poem with respect to the discourses and sensibilities available from and with which the gender is written. These voices, far from being considered exceptions in recent Argentine poetry, form a possible clue to attending to a certain soundscape that brings to life forms of listening and forms of voice traversed by obstinacy as a poetic force.El trabajo se dispone a ensayar una escucha crítica de las voces que se activan en una serie de poemas escritos por Tamara Domenech, Marina Mariasch y Fernanda Laguna, tomando como punto de partida la hipótesis de que el ritmo de estas poéticas habilita la lectura de zonas novedosas de sus obras que temáticamente no están marcadas por el género, pero que encuentran en su vocalidad una dimensión capaz de obcecar la lengua del poema respecto de los discursos y de las sensibilidades disponibles desde y con las cuales se escribe el género. Estas voces, lejos de considerarse excepciones de la poesía argentina reciente, conforman una pista posible para atender a cierto paisaje sonoro que hace sonar formas de la escucha y formas de la voz atravesadas por la obcecación como fuerza poética
Radial Growth Dynamics and Drought Resilience in Pinus pinea L. Plantations from Central-Western Argentina: Implications for Forestry Development
Full text linkForests play a crucial role in ecological stability, carbon sequestration, habitat provision and economy. As climate change intensifies, increasing drought frequency and severity challenge our understanding of forest resilience. Based on this premise, we examined radial growth dynamics and drought response of Pinus pinea L. in Mendoza Province in both mesic and xeric conditions. Using dendrochronological techniques, we assessed the long and short-term effects of soil and atmospheric drought on radial growth trends at two irrigated plantations with contrasting environments. Growth dynamics reflected differences in soil, climate, and irrigation. Growth rates were significantly higher at the mesic stand, which received nearly twice the precipitation and irrigation compared to xeric one. In contrast, growth at the xeric site was strongly limited by early-summer atmospheric drought, while late-growing season soil moisture and climatic conditions affected tree-ring development at the mesic site. Growth resilience to extreme events experienced site dependence, with edaphic drought exerting a stronger negative effect than atmospheric dry spells at the mesic stand. Our results underscore the importance of integrating short- and long-term drought assessment into P. pinea management strategies and support the potential of stone pine plantations in extra-Mediterranean South America for sustainable forestry under changing climatic conditions.
Highlights:
First dendrochronological assessment of Pinus pinea in Central-Western Argentina.
Radial growth shows site-specific sensitivity to drought types: limited by early-summer atmospheric drought at the xeric site and by late-season soil moisture deficit at the mesic site.
Irrigation does not fully decouple tree growth from climate, underscoring the need for precise water management in future plantations under semi-arid climates.
Full resilience to extreme drought is low (≤50%), with edaphic drought exerting a stronger negative impact than atmospheric drought, particularly at the mesic stand.
pinea demonstrates high potential for forestry diversification in semi-arid regions of South America, offering an alternative for sustainable nut and wood production.

Social Welfare Effects of Water Security Improvements in Arid Regions: The Case of Mendoza, Argentina
Full text linkWater security is a critical challenge in Mendoza, Argentina, an arid region that faces rising water demand and uncertainty caused by climate change. Agriculture consumes 90% of the fresh water in the region, while vineyards occupy just over 60% of the cultivated area. This study estimates the social welfare effects of an improvement in water security achieved by reallocating water from vineyards to other uses. We used a multidisciplinary approach, applying benefit transfer to estimate social welfare changes and water footprint to quantify shifts in water availability. Our findings suggest that a water security policy in the Mendocinian Northern Oasis can result in an average 21-percentage-point increase in annual water availability for other uses. This equals an average household welfare gain of 17.43 US dollars per year (95% CI: 8.40-35.64) at 2024 prices over the next 30 years. This study offers a framework for regions worldwide facing similar challenges of water scarcity, increasing water demand, and climate change. Moreover, it can support the design of more informed water management strategies to ensure long-term water security.
Highlights:
A framework is proposed for evaluating water security improvements in arid regions.
Aligning water distribution with crop water needs enables efficient water allocation.
Water security improvement policies increase social welfare for Mendocinian citizens.
A multidisciplinary approach is developed using benefit transfer and water footprint.

Translocation and Experimental Adaptation of Distichia muscoides Cushions in a Wetland Impacted by Acid Rock Drainage, Ancash, Peru
Full text linkThe deglaciation of the Andean mountain range negatively impacts ecosystems and water bodies, primarily increasing the concentration of heavy metals. However, their concentration can be reduced by applying bioremediation techniques. The objective of this study was to evaluate the effect of the translocation and adaptation of Distichia muscoides cushions in a wetland impacted by acid rock drainage in a high Andean region. For this purpose, the characteristics of water, peat, and D. muscoides tissue were compared in two wetlands, and the behavior of translocated D. muscoides was evaluated based on the bioaccumulation and translocation factors of metals. The quantification of Al, Fe, and Mn in peat, root, and aerial tissue of D. muscoides showed higher concentration values after the translocation of the cushions. Additionally, the bioaccumulation factor classified the transplanted cushions as accumulators of Al, Cu, As, Fe, Mn, and Zn, while the translocation factor classified the cushions as phytoextractors of Al, As, Cr, Fe, Mn, and Zn, and phytostabilizers of Pb and Cu. It is concluded that translocated and adapted D. muscoides cushions have potential for the bioremediation of wetlands contaminated with acid rock drainage.
Hightlights:
Two wetlands in the Andean mountains were characterized, one with apparent DAR impact and one without.
muscoides was successfully translocated and adapted to a DAR-impacted wetland.
The concentrations of heavy metals such as Al, Fe, and Mn increased after translocation in the peat, aerial tissues, and roots of muscoides.
muscoides demonstrated its potential as a phytoextractor and phytostabilizer of heavy metals.

Introducción. Economía circular y gestión inclusiva de los residuos en tiempos de reducción del Estado
No full textLa transición hacia la economía circular representa uno de los desafíos más urgentes y complejos de nuestro tiempo, pues demanda transformaciones profundas en los modelos productivos, las estructuras de gobernanza y las dinámicas de inclusion social. Este proceso cobra particular relevancia en el contexto de América Latina, donde algunos países experimentan políticas de marcada reducción del gasto público y retracción del rol del Estado en áreas clave para el desarrollo sostenible
Reciclar y reutilizar: Un análisis de la potencial instalación de una planta de separación de residuos electrónicos en Bahía Blanca
Full text linkLos procesos lineales de producción y consumo no consideran el agotamiento de los recursos naturales y la gestión de residuos. Por ello, es relevante analizar modelos que incluyan reciclado, en particular de aparatos electrónicos, cuyo daño ambiental es elevado. El objetivo es analizar la viabilidad técnica y económica de una posible planta que se dedique a esa actividad en Bahía Blanca, con el afán de aportar datos en un campo de estudio no generalizado en nuestro país. Se aplicó el método tradicional de evaluación de proyectos de inversión (estudio de mercado, técnico, legal, económico) usando información secundaria y realizando una encuesta a familias y un censo a reparadores de estos aparatos. Se concluyó que el proyecto no es viable y un crédito no modifica la decisión. La limitación es el requerimiento de mano de obra, por lo que se recomiendan otras alternativas de contratación

Específicamente, este trabajo aborda el mercado del cordero patagónico, un producto de gran valor económico y cultural para la región, cuya cadena productiva depende críticamente del precio del producto y para el cual no existen estudios predictivos previos. El objetivo principal fue desarrollar una metodología de pronóstico dinámica y robusta que permitiera seleccionar, entre un conjunto de algoritmos, el apropiado para realizar proyecciones del precio promedio del cordero patagónico
Transition Management and Dairy Cow Performance: Insights from Dairy Farms in Argentina
Full text linkThis study aims to describe nutritional strategies, management practices, and health events in transitioning cows on 28 commercial dairy farms in Argentina, selected based on their association with graduate students. During 2022, we surveyed herd management, feeding, health events, and milk yield, based on local research and validated recommendations. Most cows were housed in dry lots, with 97% of farms having far-off and close-up groups, but only half had a fresh group. The average dry period was 59±11.4 days. The mortality and culling rate were 1.2% and 1.4%, respectively. The herd incidence rates were 1.8% for milk fever, 0.3% for clinical mastitis, 2.7% for metritis, and 1.4% for retained placenta. All farms used anionic diets and monitored urinary pH, with corn silage included in all diets, and soybean meal/expeller as the main protein source. Lactating cows produced an average of 33.8±10.43 kg of milk on the first test day and 38.2±10.05 kg at peak. Primiparous cows produced 75% of the milk of mature cows. Bulk tank milk averaged 3.9±0.19% fat and 3.5±0.07% CP. This report highlights strengths and areas for improvement in Argentina’s dairy transition programs.
Highlights:
Surveyed transition cow management and performance on 28 Argentine dairy farms, providing novel regional data.
Strengths: Routine far-off and close-up grouping, widespread use of negative DCAD diets, and frequent bunk monitoring contributed to low incidence of health disorders, culling, and mortality.
Milk composition showed above-average fat and protein content, reflecting effective nutritional strategies.
Challenges: Lack of fresh groups, grouping primiparous with multiparous cows, limited shade, and extended dry periods (>50 d) increased risks of social stress and overconditioning.
Opportunities: Improve forage sampling frequency, refine energy balance prepartum, and enhance cow comfort to optimize productivity and sustainability.This study aims to describe nutritional strategies, management practices, and health events in transitioning cows on 28 commercial dairy farms in Argentina, selected based on their association with graduate students.
