El dolor-sensación y su diferencia respecto de los sentimientos abiertos a disvalores
Authors: Fernández Beites Pilar
Published: July 2019

Frente a la confusión que encontramos en la literatura, debemos distinguir con claridad la sensación y el sentimiento para poder decidir en qué ámbito se inscribe el dolor. El artículo defiende la tesis de Stumpf y Husserl de que el dolor (dolor físico) es fundamentalmente sensación. Pero, ya no en línea con Stumpf, sino con Scheler, se sostiene que además del dolor-sensación, existen sentimientos sensibles, a los que se propone denominar «displacer» (no intencional) y «desagrado» (intencional). Entre los sentimientos de desagrado hay algunos con intencionalidad trascendente, que son los ligados a las sensaciones exhibitivas (vista, oído…). Pero también hay un sentimiento de «desagrado» ligado al dolor-sensación, que tiene una intencionalidad inmanente (y cuya base sentimental es el «displacer»). El desagrado y el displacer ligados al dolor-sensación pueden ser denominados dolorsentimiento, pero han de distinguirse claramente del dolor-sensación.
La afectividad como fundamento fenomenológico de la comunidad y la experiencia del otro
Authors: Díaz Erbetta Myriam Ximena
Published: July 2019

La comprensión y el análisis del problema de la intersubjetividad y la experiencia del otro ha sido un ámbito controvertido para la fenomenología en general, y no es excepción en la fenomenología de la vida de Michel Henry. La fenomenología henryana presenta como núcleo de su reflexión la subjetividad, que es concebida como realidad encarnada (es un cuerpo, una carne), una realidad afectiva y fundamentalmente viviente, cuya praxis se expresa en el trabajo subjetivo viviente. Desde este punto de partida filosófico, la alteridad, la intersubjetividad y la comunidad sólo son posibles para Henry desde la afectividad, que es concebida como el único horizonte de la manifestación, ya no de la subjetividad solamente, sino de toda manifestación posible, es decir, como esencia de la manifestación.

Published: July 2019

The objective is to develop photoreduction method catalyzed by TiO2 for the decreasing Hg(II) concentration. Photocatalytic reduction was carried out in a closed reactor equipped with UV lamp, by irradiating and stirring a mixture of Hg(II) solution and TiO2 photocatalyst powder for a certain period of time. The amount of reduced Hg(II) by photoreduction was calculated by substracting initial Hg(II) concentration with unreduced one, which was determined using cold vapor atomic absorption spectrophotometry method. The result of the research indicated that the use of TiO2 photocatalyst has increased the effectiveness of Hg(II) photoreduction. In the photocatalysis process TiO2 exposured by photon energy could resulted in •OH radicals and electrons that can recombined in the same time. The presence of p-chlorophenol in the solution mixture increased the photoreduction effectiveness probably due to its capability in capturing •OH radicals.TiO2 decreases in its crystalinity up to 15.54 % after process.Keywords: photoreduction, Hg(II), TiO2, p-chlorophenol

Published: July 2019

Zeolit merupakan aluminosilikat dengan struktur kerangka tiga dimensi, memiliki rongga serta saluran yang saling berhubungan menyebabkan bagian permukaannya menjadi sangat luas. Luas permukaan dan pori zeolit sering dimanfaatkan untuk mengadsorp adsorbat. Dalam efektifitasnya sebagai adsorben, situs asam dan permukaan zeolit alam dapat dimodifikasi dengan ligan EDTA (etilendiamintetraasetat/ ethylenediaminetetraacetic acid). Dengan ligan EDTA diharapkan zeolit menjadi lebih selektif dalam mengadsopsi ion logam Pb2+. Pada penelitian ini zeolit alam (ZA) dimodifikasi dengan ligan EDTA pada variasi konsentrasi yaitu 0,20 M, 0,15 M, 0,10 M dan 0,05 M. Selanjutnya digunakan untuk mengadsorpsi ion logam Pb2+ dan Cd2+ dengan variasi: (i) ukuran partikel ZA 212 pm, 125 pm, dan 90 pm, (ii) rasio adsorbat/adsorben pada 20 mL/g, 30 mL/g, 40 mL/g dan 50 mL/g. Pada penelitian ini juga dilakukan perbandingan kemampuan adsorpsi ZA-EDTA terhadap ion Pb2+ dan Cd2+ dengan kemampuan adsorpsi ZA terhadap kompleks Pb-EDTA dan Cd-EDTA. Hasil penelitian menunjukkan bahwa spektra FTIR ZA sebelum maupun sesudah modifikasi dengan ligan EDTA tidak menampakkan perbedaan yang signifikan. Namun demikian kemampuan ZA setelah modifikasi dengan ligan EDTA (ZA-EDTA) dalam mengadsorpsi logam lebih tinggi. Hasil uji adsorpsi terhadap ion Pb2+ dan Cd2+ menunjukkan bahwa adsorpsi tertinggi oleh ZA-EDTA dengan ukuran partikel ZA 212 pm, sedangkan rasio adsorbat/adsorben terbaik untuk ion Pb2+ adalah 30 mL/g dan untuk ion Cd2+ adalah 20 mL/g. Dari perbandingan yang telah dilakukan juga diketahui bahwa adsorpsi yang dilakukan oleh ZA-EDTA terhadap ion Pb2+ dan Cd2+ lebih baik daripada adsorpsi ZA terhadap kompleks Pb-EDTA dan Cd-EDTA.

Growth of population increases the consumption of nonbiodegradable plastic which causes waste buildup. Diversion of plastic material from nonbiodegradable material to biodegradable is an important alternatif. PLA is a plastic polymer that is easily degraded but very brittle. Palm oil waste containing oil palm empty bunches has the potential as a reinforcement material because the cellulose content is 30-40%. Minimizing size to nanoscale will increase the surface area and dispersion ability of cellulose dispersibility into the PLA polymer matrix, thus increasing compatibility in terms of and mechanical properties and surface morphology of the composite. Hydrolysis by strong acid and centrifugation at 5000 rpm succeeded in making cellulose nanocrystal with index of polidisperse 0.5 and average particle diameter of 7.967 nm. CTAC as a solubilizer and surface modifier agent successfully made interaction to cellulose nanocrystal as confirmed on absorption at wave number 2850 cm-1, 2960 cm-1 and 720 cm-1. Modified At the fixed CTAC concentration of 0.2 mol, the best mechanical properties of CNC-PLA composites were obtained in the composition ratio of 90: 10 with tensile strength of 26.295 MPa, elongation break of 68.18%, and Young modulus of 0.387 Gpa. The greater the CTAC added to nanocrystal cellulose, the lower the reinforcement value and the less reduction. Based on the results of morphology surface characterization, PLA surfaces required for degradation were obtained.
Radioguided surgery: physical principles and an update on technological developments
Authors: Pashazadeh Ali , Friebe Michael
Published: July 2019

Radioguided surgery (RGS) is the use of radiation detection probes and handheld gamma cameras in surgery rooms to identify radioactively labeled lesions inside the body with an aim to improve surgical outcome. In today’s surgery, application of these devices is a well-established practice, which provides surgeons with real-time information to guide them to the site of a lesion. In recent years, there have been several major improvements in the technology and design of gamma probes and handheld gamma cameras, enhancing their applications in surgical practices. Handheld gamma cameras, for example, are now moving from single-modality to dual-modality scanners that add anatomical data to the physiologic data, and with that provide more clinical information of the tissue under study. Also, in the last decade, a radioguided surgical technique based on the Cerenkov radiation was introduced, with more improved sensitivity in identifying radioactively labeled lesions. Additionally, recent advances in hybrid tracers have led to more efficient detection of lesions labeled with these tracers. Besides, it seems that combining medical robotics and augmented reality technology with current radioguided surgical practices potentially will change the delivery and performance of RGS in the near future. The current paper aims to give an overview of the physics of RGS and summarizes recent advances in this field that have a potential to improve the application of radioguided surgical procedures in the management of cancer.

Pharmacodynamic interaction of cumin seeds (Cuminum cyminum L.) with glyburide in diabetes
Authors: Kaur Ginpreet , Upadhyay Nidhi , Tharappel Leo J Philip , Invally Mihir
Published: July 2019

Background and objective

The plethora of anti-diabetic agents available today has many side effects, especially on chronic usage. Hence, alternative approaches utilizing natural and synthetic agents are sought after. Cumin has been shown to be beneficial in treating diabetes. This study evaluates the anti-diabetic effect of cumin and glyburide in the streptozotocin induced diabetes model in rats, and investigates their pharmacodynamic interactions and its implication in diabetes.

Methodology

The phytoconstituents present in the ethanolic cumin seed extract were determined using appropriate analytical methods. After acute toxicity studies (OECD 2001), the anti-diabetic effect of the extract was evaluated in wistar rats. The rats were divided into five groups – Groups I and II served as the normal and diabetic control. Group III was the standard control (glyburide 5 mg/kg), while groups IV and V received the extract (600 mg/kg) and a combination of the extract (600 mg/kg) and glyburide (2.5 mg/kg; half dose). Biochemical parameters viz. plasma glucose and glycosylated haemoglobin, were measured periodically during the 28 day treatment. On the 28th day, oral glucose tolerance test, lipid profile, renal profile and histopathological evaluation were performed after completion of the study. To investigate the nature of herb-drug interaction, HPLC analysis for estimation of glyburide concentration in the blood was conducted.

Results

Acute toxicity studies showed the extract to be safe till a dose of 2 g/kg. The extract alone, and in combination with glyburide (half-dose), significantly lowered elevated glucose (by more than 45% from baseline; without producing hypoglycemia), and other lipid and renal parameters. The effects produced by 2.5 mg/kg glyburide, and 5 mg/kg glyburide (without extract) were similar. Histopathological analysis also showed that the extract was able to reverse the degeneration brought about by streptozotocin which was especially notable on the pancreatic and renal tissue. HPLC analysis revealed differing pharmacokinetics of glyburide in the groups treated with 5 mg/kg dose, and 2.5 mg/kg + 600 mg/kg extract.

Conclusion

The results obtained in this study suggest that Cuminum cyminum L. is a promising anti-diabetic agent, and exhibits pharmacodynamic interaction with glyburide to mitigate symptoms of diabetes mellitus.
Warionia saharae induces antihypertensive and vasorelaxant activities through nitric oxide and KATP channels pathways in rats
Authors: EL-Ouady Fadwa , Eddouks Mohamed
Published: July 2019

Background

Warionia saharae Bentham & Cosson. is used in traditional medicine to treat many diseases including hypertension.

Method

The present study was designed to investigate the antihypertensive activity of aqueous extract of Warionia saharae (WSLAE) in anesthetized L-NAME (Nω-L-arginine methyl ester)-induced rats. The acute and sub-chronic effects of WSLAE on systolic, diastolic, mean arterial blood pressure and heart rate (HR) were investigated after oral administration of the extract (100 mg/kg body weight of WSLAE) during 6 h for the acute experiment and during 7 days for the sub-chronic test. In addition the effect of WSLAE on the contractile response of isolated rat aortic rings was tested and the role of the vascular receptors was evaluated using several drugs.

Results

The results showed that WSLAE induced a significant decrease in the systolic, diastolic, mean arterial blood pressure and HR in both normotensive and hypertensive rats. Furthermore, this extract induced relaxation in rings pre-contracted with Epinephrine (10 µM) or with KCl (100 mM). This vasorelaxant capacity seems to be mediated through inhibition of KATP channels and nitric oxide (NO) synthase pathways.

Conclusion

This study supports the use of Warionia saharae in the management of hypertension in Moroccan traditional medicine.

Published: July 2019

A rapid high performance liquid chromatography (HPLC) and thermal ionisation mass spectrometric (TIMS) methods have been developed for the separation and estimation of fission product elements molybdenum and lanthanum for the burn-up measurements on the dissolver solution of Indian pressurised heavy water reactor (PHWR) spent fuel. Reverse phase chromatography method was developed to separate molybdenum from dissolver solution using mandelic acid as mobile phase and a dynamic ion exchange chromatography technique was used for the separation of lanthanum as well as neodymium from a dissolver solution. Sample loading methods which resulted in enhanced ionisation efficiency have been developed for the TIMS analysis of HPLC separated molybdenum and lanthanum fractions. Ascorbic acid mixed with silicic acid in HCl medium was used for loading the molybdenum on to a rhenium filament to obtain stable and intense ion beam. A novel sample loading method for lanthanum in which a mixture of graphite + boric acid (H3BO3) + silica gel was employed to achieve enhanced and steady ion beam formation of LaO+. Concentrations of species of interest were determined employing suitable spikes by isotope dilution mass spectrometry (IDMS) method. The developed methods were adopted for PHWR dissolver solution to establish molybdenum and lanthanum as alternate burn-up monitors. The burn-up data obtained were compared with the well established method of neodymium as fission product monitor. This is a first study of its kind where the data obtained by using molybdenum and lanthanum as fission product monitors were compared with that obtained by Nd-148 method.

Citrate-capped gold nanoparticles (Gnps) have multiple applications in all optical devices and influence the properties of birefringence in liquid crystalline (LC) molecules. In the present paper, systematic studies have been carried out on LC compounds p-n-undecyloxy benzoic acid (11oba) and p-n-dodecyloxy benzoic acid (12oba) with dispersed citrate-capped Gnps in different low molar concentrations. The phase transition temperatures of the LC nanocomposites obtained from polarizing thermal microscopy (POM), differential scanning calorimetry (DSC) and modified spectrometry are found to be reduced with the increase in concentration of dispersed citrate-capped Gnps. The information was obtained from textural data utilizing the simple technique gradient measurement of standard deviation (GMSD) using the MATLAB tool, which is analogous to DSC. Further, the existence of citrate-capped Gnps in 11oba and 12oba was determined by spectroscopic techniques like ultraviolet-visible spectrometry and scanning electron microscopy. The birefringence measurements were carried out at different wavelengths (460, 500, 570 and 635 nm) using a wedge-shaped cell with a modified spectrometer. The birefringence (δ
n) increases with increase in weight concentration of citrate-capped Gnps in the nematic thermal range. Further, the order parameter S values obtained from the Kuczynski internal field model, the Vuks model, the Haller extrapolation model and the effective geometry parameter methods are in good agreement. It is found that the order parameter S increases with increase in dispersion of concentration of citrate-capped Gnps. This is due to strong Van der Waal’s interaction between the LC molecules and citrate-capped Gnps, which increases the alignment of the LC molecules.
Effect of Moisture on Full-Scale Pavement Distress
Authors: Camacho-Garita Edgar , Aguiar-Moya J. P. , Ávila-Esquivel T. , Loría-Salazar L. G.
Published: July 2019

The effect of moisture is fundamental in determining pavement responses. It becomes more important in tropical regions where high precipitation rates and high variability in water table levels are present. The results indicate that when comparing the quantitative performance of pavement sections that are subjected to near saturation conditions, the bearing capacity of the pavement structure can be as low as 5 % of that associated to the same structure but with optimum water content. The damage in the saturated pavement sections is greatly accelerated because of pumping of fines from the subgrade and the subbase. All the pavement layers are affected by loading (decrease or increase in layer moduli) but to a different degree depending on the moisture conditions. Furthermore, the effect of moisture is greater in the cohesive soils and contaminated granular materials. Finally, the relatively stiffer layers (i.e., hot mix asphalt and cement-treated base layers) are the ones that are more susceptible to a higher deterioration rate, particularly under saturated or near saturated conditions.

Primary and continuous cell culture systems are a good in vitro alternative for the quantitative assessment of snake venom toxicity. There are still few studies evaluating the cellular response against Bothrops leucurus venom (BlV). This study aimed to evaluate the cytotoxic effect of crude BlV on culture of VERO E6 cells. Neutral Red incorporation (NR) and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT) tests were performed for viable cells, and Trypan Blue (TB) dye exclusion test was performed for non-viable cells. The differences between the groups were evaluated by ANOVA-One-Way and Dunnet through the program Graph Pad 5.0 with significance of 5%. The 50% cytotoxic concentration (CC50) of BlV was 7.86 μg/mL. There was a trend of dose-dependent reduction on cell viability in all assays evaluated. However, MTT and NR tests were more sensitive for the evaluation of BlV cytotoxicity on the VERO E6 cell line.

Plasma exchange and early thyroidectomy in thyroid storm requiring extracorporeal membrane oxygenation
Authors: Koh Huilin , Kaushik Manish , Loh Julian Kenrick , Chng Chiaw Ling
Published: July 2019

Thyroid storm with multi-organ failure limits the use of conventional treatment. A 44-year-old male presented with thyroid storm and experienced cardiovascular collapse after beta-blocker administration, with resultant fulminant multi-organ failure requiring inotropic support, mechanical ventilation, extracorporeal membrane oxygenation (ECMO) and continuous renal replacement therapy. Hepatic and renal failure precluded the use of conventional thyroid storm treatment and early plasma exchange was instituted. The patient underwent emergency thyroidectomy after four effective exchanges, with subsequent rapid reversal of multi-organ failure. The challenges of institution of plasma exchanges with ongoing ECMO support, dialysis and timing of thyroidectomy are discussed. This case highlights the important role of early therapeutic plasma exchange (TPE) as an effective salvage therapy for lowering circulating hormones and stabilization of patients in preparation for emergency thyroidectomy in patients with thyroid storm and fulminant multi-organ failure.

Learning points:

Administration of beta-blockers in thyroid storm presenting with congestive cardiac failure may precipitate cardiovascular collapse due to inhibition of thyroid-induced hyperadrenergic compensation which maintains cardiac output.

TPE can be an effective bridging therapy to emergency total thyroidectomy when conventional thyroid storm treatment is contraindicated.

End-organ support using ECMO and CRRT can be combined with TPE effectively in the management of critically ill cases of thyroid storm.

The effectiveness of plasma exchange in lowering thyroid hormones appears to wane after 44–48 h of therapy in this case, highlighting the importance early thyroidectomy.

Este se enmarca en el sistema general de evaluación en la Universidad, que persigue fundamentalmente el mejoramiento y no el control. El sistema de evaluación de profesores incluye la evaluación de desempeños académicos y administrativos, la evaluación de sus obras de producción intelectual y la evaluación de ciertos logros, tales como la obtención de segundos títulos universitarios, la realización de cursos formales no conducentes a título, la obtención de distinciones académicas y la competencia en idiomas no nativos. A través del conocimiento que se genera en los procesos de evaluación y de los incentivos establecidos en le Reglamento del Profesorado, los profesores y la institución ha tomado acciones de mejoramiento que han llevado a un nuevo perfil del profesorado en la Universidad. La dedicación de los profesores ha aumentado notablemente lo cual ha permitido la conformación de una comunidad profesoral científica y estable; la composición del cuerpo profesoral ha mejorado sustancialmente en lo relativo a títulos de postgrado; la producción intelectual se ha incrementado enormemente; y se ha multiplicado los logros de los profesores.

Unidades Productivas Integrales, como un producto Turístico para el Desarrollo Rural Sustentable
Authors: Montero-Herrera Sonia Lucía
Published: July 2019

Las Unidades Productivas Integrales (UPI), son un sistema  de producción que permite el uso óptimo de los recursos naturales y culturales, por medio del manejo de tecnologías de bajo costo, que  promueven  un desarrollo endógeno y auto sostenible y alta diversidad de productos agropecuarios, forestales y energéticos de origen local o adaptados al territorio.

Se caracterizan por ocupar  mano de obra familiar, productos orgánicos de origen autóctono, comercializables y encadenables al producto turístico local.  Su importancia, radica en que proporcionan, seguridad alimentaria, manejo integrado de los recursos, protección del medio ambiente, formación de microempresas y organización comunitaria.  Por esta razón la Universidad Nacional de Costa Rica (UNA) con sus proyectos de extensión universitaria, acompañan a estas comunidades indígenas en la implementación de estas unidades. Como proyecto denominado: Autogestión y sostenibilidad de las unidades productivas en territorios indígenas del Valle la Estrella, con miras a la consolidación de un sistema de producción basado en una cosmovisión indígena e intercambio de saberes ancestrales en el Territorio Indígena Tayni, en el Valle de la Estrella, Limón, Costa Rica; el cual con  técnicas participativas que tienden a favorecer el intercambio de saberes ancestrales como instrumento de aprendizaje.  En este territorio la UNA ha logrado replicar el modelo de las UPI, en todos los centros educativos en torno a la primera iniciativa creada en el 2015, permitiendo la diversificación de los productos alimentarios en comedores estudiantiles locales y en la comunidad  y en general, el rescate de productos medicinales tradicionales del bosque, y de la cultura local. El proyecto ha generado empoderamiento local y ha creado la  necesidad de incursionar en iniciativas de turismo rural comunitario, enfocado en los saberes ancestrales locales. Asociado con la motivación de los estudiantes de los centros educativos para ingresar en un futuro a la UNA, donde actualmente  hay cinco estudiantes de este territorio de los cuales cuatro ya están por graduarse en las diferentes carreras del campus Sarapiquí.
Permaculture demonstration sites in Central America: contributions to agroecological transition and implications for educators
Authors: Conz Brian W.
Published: July 2019

Central America has been an important region for the agroecological revolution, building on a history of intensive smallholder farming practices, farmer-to-farmer knowledge sharing and agrarian social movements.  Permaculture is an approach to ecological site design and agroecological transition, which has grown in popularity in Central America in recent years.  Permaculture’s entrance into the larger movement for agroecology in Central America raises some important questions.  How does permaculture intersect with these existing forces?  How can permaculturalists address perceptions that it is yet another colonialist development intervention by well-meaning Northerners?  What are the implications for educators who visit permaculture demonstration sites with students?  In order to explore these questions and to contribute to discussions regarding permaculture’s contribution to agroecological transition in Central America I visited two permaculture demonstration sites and participated in site tours.  I discussed site features with farmers and gathered information from farm websites.  I bring these experiences into conversation with the academic literature on agroecology and permaculture.  I conclude that permaculture sites make valuable contributions to agroecological transition in Central America.  I also identify important risks that sustainability educators using permaculture demonstrations sites should be aware of and I offer suggestions for addressing these risks.
Ordenamiento en disputa y espacialización de la injusticia en Colombia
Authors: Velez-Torres Irene , Pérez-Pérez José Joaquín , Riascos-Riascos Diver Antonio
Published: July 2019

Este artículo analiza las relaciones entre ordenamiento territorial y reconocimiento étnico a partir de las experiencias de dos comunidades afrodescendientes localizadas en el valle plano del río Cauca, Colombia: El Hormiguero y El Tiple. Se ilustran las tensiones del Estado colombiano, surgidas entre el reconocimiento diferenciado de derechos a las poblaciones étnicas y los mecanismos para ordenar el uso y la apropiación de la naturaleza. La metodología empleada tuvo un enfoque cualitativo de tipo etnográfico y archivístico, donde se privilegió la interacción con las comunidades organizadas en torno a los Consejos Comunitarios y la revisión del extenso archivo normativo que sustenta el ordenamiento territorial municipal. El análisis comparativo de los casos de El Hormiguero y El Tiple demuestra una forma institucionalizada de injusticia espacial dada la imposición de facto de intereses económicos privados sobre el ordenamiento de los territorios. Injusticia que ha privado a las comunidades afrodescendientes de los derechos étnicos adquiridos, como el reconocimiento, el territorio y la consulta previa, libre e informada.Ideas destacadas: artículo de investigación sobre el confinamiento de las comunidades afrodescendientes en el valle plano del río Cauca que implica injusticia en cuanto a la distribución de la propiedad y del uso del suelo. La segmentación espacial causada por la expansión de la caña de azúcar ha sido instituida por instrumentos de planificación territorial, incluso negando derechos constitucionales de estas comunidades.
Protagonismo das mulheres assentadas no Território Rural do Bolsão-ms: gênero, território e resistência camponesa
Authors: Vilela Borzone Clariana , Aparecida de Almeida Rosemeire
Published: July 2019

O Território Rural do Bolsão, área que compreende oito municípios na região leste de Mato Grosso do Sul, Brasil, tem sido palco da expansão dos monocultivos de eucalipto, acirrando as disputas territoriais entreo campesinato e a agricultura capitalista. As mulheres que residem nos assentamentos de reforma agráriainstalados nessa área têm protagonizado importantes ações para a construção da resistência camponesa. Para melhor compreensão desse protagonismo, buscou-se dar visibilidade às questões de gênero desenvolvidas no campo. A pesquisa foi feita por meio de levantamento de referencial teórico, coleta de dados, trabalhos decampo e entrevistas feitas com 23 mulheres de cinco assentamentos. Revelaram-se o aumento da participação feminina na esfera pública, bem como mudanças na divisão sexual de tarefas no âmbito privado. Tais mudançasdialogam com os debates da agroecologia e da soberania alimentar, e destacam a importância do esforçofeminista entremeado às questões de luta e permanência na terra no contexto neoliberal atual. Ideias destacadas: artigo de investigação sobre o protagonismo das mulheres dos assentamentos da reforma agrária na construção da resistência camponesa, no contexto da expansão de monocultivos, analisados por meio de levantamento de dados estatísticos e entrevistas com mulheres de cinco assentamentos do Território Rural do Bolsão, Mato Grosso do Sul, Brasil.
Nacidos, criados, llegados: relaciones de clase y geometrías socioespaciales en la migración neorrural de la Argentina contemporánea
Authors: Quirós Julieta
Published: July 2019

En diversos países de Latinoamérica y Europa, el progresivo desplazamiento de clases medias urbanas hacia pequeñas localidades rurales del “interior” ha pasado a constituir, en las últimas dos décadas, una modalidad sui géneris de migración interna. Los estudios rurales se refieren a este fenómeno migratorio con el nombre de “neorruralismo”. Este artículo propone estudiar el movimiento neorrural desde una perspectiva geopolítica, entendiéndolo como proceso de (re)inscripción espacial de relaciones de clase y desigualdades históricamente configuradas. El estudio se basa en una investigación etnográfica centrada en el análisis de procesos migratorios que tienen por escenario una región serrana de la provincia de Córdoba, Argentina. Explorando la dinámica cotidiana de las relaciones de alteridad entre poblaciones autóctonas (“nacidos y criados”) y migrantes (“venidos o llegados”), la investigación identifica los modos en que las condiciones estructurales de desigualdad configuran situaciones de injusticia espacial y procesos de desposesión del espacio y otros bienes socialmente significativos. Como resultado, se plantea la necesidad epistemológica y política de una agenda de investigación orientada a interrogar la migración neorrural desde una perspectiva de clase, como también de diseñar políticas de la diferencia y la autoctonía orientadas a mitigar o revertir la configuración e invisibilización de geografías injustas.Ideas destacadas: artículo de investigación que propone una agenda orientada a interrogar la migración neorrural contemporánea en perspectiva de clase, en pro de identificar y combatir desigualdades e injusticias espaciales socialmente invisibilizadas.
Justicia espacial, desastres socionaturales y políticas del espacio: dinámicas sociopolíticas frente a los aluviones y proceso de recuperación en Copiapó, Chile
Authors: Astudillo Pizarro Francisco , Sandoval Díaz José
Published: July 2019

Se exploran las dinámicas sociopolíticas derivadas de los aluviones de mayo de 2017 en la comuna de Copiapó, región de Atacama, Chile. Asumiendo una perspectiva procesual, se examinan las relaciones entre las prácticas de organización y contestación local, frente a las políticas del espacio bajo el contexto de las inundaciones y los procesos de rehabilitación posterior. Se exploran teóricamente algunas de las principales discusiones conceptuales en torno a la justicia espacial, vinculándolas al campo de los riesgos y desastres socionaturales. En esta perspectiva, se busca identificar y caracterizar las dinámicas sociopolíticas de los actores locales en tres puntos críticos localizados tanto en el área urbana como en sectores periurbanos y rurales en la comuna de Copiapó. Para el análisis, se recurrió a una combinación de estrategias de etnografía contemporánea. El análisis empírico muestra que estas dinámicas asumen configuraciones tácticas diferenciadas de afrontamiento; no obstante, a diferencia de los aluviones de 2015, en los que las explicaciones tendieron a los elementos naturalistas del desastre, el periodo estudiado presenta una marcada transición hacia una explicación híbrida con fuerte énfasis en los elementos políticos, expresada en críticas hacia el rol del Estado subsidiario. Como consecuencia, se configuran marcos de explicación de tipo socionatural del desastre.Ideas destacadas: artículo de investigación sobre los vínculos teóricos entre justicia espacial y riesgos de desastres socionaturales, a partir de una serie de experiencias empíricas derivadas de los aluviones ocurridos en 2017 en la comuna de Copiapó. Se examinan las formas de agenciamiento y las dinámicas sociopolíticas en tres comunidades y territorios durante el proceso de recuperación.
