Metodologías de sistematización de información sobre violaciones a los derechos humanos en Argentina. El “armado del caso” ante la Comisión Interamericana de Derechos Humanos (1979)
Authors: Balardini Lorena
Published: February 2018

Este trabajo presenta los hallazgos de una investigación que analizó la sistematización de información como estrategia de las organizaciones de derechos humanos en Argentina, en el marco de su lucha en pos de la verdad y la justicia por los crímenes de la última dictadura militar (1976-1983). La investigación sostiene que la sistematización de información ha sido una de las estrategias menos analizadas y, en general, es caracterizada como “artesanal” sin tomar en cuenta sus métodos, reglas estructurantes y lógicas.

El análisis teórico se centró en el ámbito particular en el que se desarrolló la lucha de estas organizaciones, la “arena legal” o el “campo jurídico”, y mostró que han sido sus reglas las que estructuraron las estrategias de sistematización. Esto posibilitó conceptualizar el “hecho represivo” y darle la forma específica que requería para poderlo convertir en un caso judicial.

La investigación presenta un abordaje cualitativo a partir del análisis de material de archivo y de entrevistas en profundidad a informantes clave. En este artículo se aborda una estrategia particular: la producción de patrones represivos a partir de denuncias de desaparición en el marco de la visita a Argentina de la Comisión Interamericana de Derechos Humanos en 1979.
Colombia: país donde abundan las leyes y escasea la legalidad
Authors: Angarita Jairo
Published: February 2018

Ocuparnos de la eficacia del derecho y de la legalidad, y más específicamente de la cultura de aprehender el ordenamiento jurídico a pesar de la inflación normativa y de la concepción reinante de pretender resolver toda problemática social con la expedición de normas jurídicas no es un asunto pacífico.
Sin embargo, nuestra sociedad debe reflexionar si está transitando el camino adecuado para hacer del derecho una herramienta que permita modelar las conductas de sus asociados o si, por el contrario, requiere no hacer tanto énfasis en la norma jurídica y más bien apoyarse en la norma social y moral para llegar a niveles mayores de aceptación de la norma como parte de la regularización en el trasegar cotidiano del individuo.
Una reflexión en el orden planteado no solo debe llevarnos a considerar netamente la existencia de una ineficacia normativa y una cultura generalizada del incumplimiento, sino también a reformular si merece un país como el nuestro demandar tantos esfuerzos económicos e institucionales para dictar un marco jurídico que no parece cumplir su propósito.

La populicultura en Norpatagonia, principalmente en la provincia de Río Negro, comenzó con el objetivo de establecer cortinas rompevientos para proteger cultivos frutihortícolas en sus valles irrigados. En la actualidad existen 6000 km de longitud lineal de cortinas y unas 900 ha de plantaciones en macizo de álamo en dicha provincia. El destino de la madera de estos álamos es principalmente la fabricación de embalajes, pero se utiliza también en la construcción, industria del mueble, debobinado y pasta celulósica. No existe información de características y propiedades de esta valiosa materia prima, que es necesaria para optimizar su aprovechamiento y maximizar su valor en diferentes usos. En este trabajo se describen características estéticas, algunas características microscópicas y propiedades físicas de la madera de Populus nigra cv thaisiana, P. alba var bolleana y P. x canadensis ‘conti 12’, a partir de cinco ejemplares adultos de cada especie, provenientes de cortinas rompevientos de la localidad de Allen, provincia de Rio Negro, Patagonia Argentina. La baja densidad (< 0.40) y las características estéticas de la madera de las tres especies determinan su calidad para debobinado, pasta celulósica y fabricación de envases y embalajes. Los valores de contracción volumétrica (11.82%, 10.32% y 12.15%, respectivamente) y del coeficiente de contracción (V: 0.36 - 0.37) indican su ubicación entre las maderas medianamente nerviosas (medianamente estables). Los índices de anisotropía altos (A > 2.3) revelan su baja estabilidad dimensional, indicando la necesidad de realizar correctos secados de la misma para su uso en aberturas y revestimientos.

Изоэлектронные центры кислорода и проводимость кристаллов CdS в сравнении с PbS
Authors: Морозова Н.К. , Мирошников Б.Н.
Published: February 2018

AbstractThe influence of oxygen on the electrical properties of PbS are well known. The goal of this study is to compare and reveal this phenomenon in CdS(O) single crystals, which we have studied in detail previously. The experiments are performed for CdS single crystals with a known oxygen concentration, deviation from stoichiometry, and definite set of intrinsic point defects. They allow us to confirm the results described for PbS and clarify their nature. It is shown that the phenomenon is based on the capture of free charge carriers— electrons—by acceptor-like isoelectronic O_S centers with the subsequent formation of associates having a complex structure. Previous conclusions on the dissolution mechanism of oxygen in CdS with deviations from stoichiometry are confirmed. Variations in the electrical properties in oxygen-activated PbS(O), similarly to CdS(O), showed that isoelectronic oxygen centers O_S are present in lead sulfide.

AbstractMathematical simulation of the cascade of displacements in SiC is used to consider the specific features of Frenkel-pair generation upon the scattering of 8- and 15-MeV protons. The distribution histograms of energies acquired not only by primary knocked-out atoms, but also by recoil atoms generated in displacement cascades, are calculated. An analysis of the histograms considers two energy ranges. In the first range of “low” energies, the spontaneous recombination of genetically related Frenkel pairs is dominant. Recoil atoms in the second range have a higher energy, which enables these atoms to leave the spontaneousrecombination zone and dissociate into isolated components. The compensation of lightly doped n - and p -4 H -SiC samples grown by gas-phase epitaxy is experimentally studied under irradiation with 8- and 15-MeV protons. The carrier removal rates are measured. The calculated and experimental data are compared and estimates are obtained for the size of the spontaneous-recombination zone.

AbstractCopper (I) oxide and zinc oxide films are formed on silicon and glassy quartz substrates by magnetron assisted sputtering. The thickness of the films is tens and hundreds of nanometers. The films are grown at different substrate temperatures and different oxygen pressures in the working chamber. The film samples are studied by the X-ray diffraction technique, scanning electron microscopy, and optical methods. It is established that an increase in the substrate temperature yields a change in the surface morphology of copper (I) oxide films towards the formation of well-pronounced crystallites. The reflectance and Raman spectra suggest that the quality of such films is close to that of bulk Cu_2O crystals produced by the oxidation of copper. As concerns ZnO films, an increase in the substrate temperature and an increase in the partial oxygen pressure make it possible to produce films, for which a sharp exciton structure is observed in the reflectance spectra and the emission of excitons bound at donors is observed in the luminescence spectra.

AbstractThe transition from a two-domain to one-domain surface on a Si(100) substrate is investigated. It is demonstrated using reflection high-energy electron diffraction that at a temperature of 600°C and a deposition rate of 0.652 Å/s onto a Si(100) substrate pre-heated to 1000°C and inclined at an angle of 0.35°C to the plane, a series of reflections from the 1 × 2 superstructure completely vanishes at a constant flow of Si. This is attributed to the transition of the surface from monoatomic to diatomic steps. At growth rates lower than 0.652 Å/s, the transition from a two-domain to one-domain surface is also observed; with a decrease in the growth rate, the intensity ratio I _2 × 1/ I _1 × 2 decreases and the maximum of the dependences shifts toward lower temperatures. The complete vanishing of the series of superstructural reflections after preliminary annealing at a temperature of 700°C is not observed; this series only vanishes after annealing at 900 and 1000°C. The growth of Ge islands on a Si(100) surface preliminary annealed at a temperature of 800°C is studied. It is shown that the islands tend to nucleate at the step edges. A mechanism of Ge island ordering on the Si(100) surface is proposed.

AbstractThe phase formation, specific features, and the dielectric properties of the ceramics of compositions from the region of morphotropic interface in the (Na_0.5Bi_0.5)TiO_3–BaTiO_3 system modified by Bi(Mg_0.5Ti_0.5)O_3 and also low-melting additions KCl, NaCl–LiF, CuO, and MnO_2 that favor the control of the stoichiometry and the properties of the ceramics have been studied. The ceramics are characterized by ferroelectric phase transitions that are observed as jumps at temperatures near 400 K and maxima at T _m ~ 600 K in the temperature dependences of the dielectric permittivity. The phase transitions at ~400 K demonstrate the relaxor behavior indicating the existence of polar domains in the nonpolar matrix. An increase in the content of Bi(Mg_0.5Ti_0.5)O_3 favor a decrease in the electrical conductivity and dielectric losses of the samples, and the relative dielectric permittivity at room temperature ε_rt is retained quite high, achieving the highest values ε_rt = 1080–1350 in the ceramics modified with KCl.

The effect of the external magnetic field and transport current density on the kinetics of phase transitions in both subsystems of granular two-level HTSC ( T = T _ c 2J, T _ c 1g, T _ c ) is determined. The feasibility of the topological phase transition, i.e., the Berezinsky–Kosterlitz–Thouless transition, in the Josephson medium at T _ c 2J < T _BKT < T _ c 1g “in transport current” is established, and its feasibility conditions are studied.

AbstractEffect of semimetallic antimony (0.5 mol % Sb) on the dielectric properties and ac-conductivity of TlGaS_2-based single crystals grown by the Bridgman–Stockbarger method has been studied. The experimental results on the frequency dispersion of dielectric coefficients and the conductivity of TlGa_0.995Sb_0.005S_2 single crystals allowed the revealing of the dielectric loss nature, the charge transfer mechanism, and the estimation of the parameters of the states localized in the energy gap. The antimony-doping of the TlGaS_2 single crystal leads to an increase in the density of states near the Fermi level and a decrease in the average time and average distance of hopes.

AbstractWe report on the synthesis conductions and results of experimental investigations of the crystal structure and magnetic properties of a new magnetic compound YbFeTi_2O_7. According to the X-ray diffractometry data, the crystal structure of the investigated compound is described by the rhombic space group Pcnb with unit cell parameters of a = 9.8115(1) Å, b = 13.5106(2) Å, and c = 7.31302(9) Å and atomic disordering in the distribution of iron ions Fe^3+ over five structural sites. The magnetic measurements in the lowtemperature region revealed a kink in the temperature dependence of the magnetic moment and its dependence on the sample magnetic prehistory. The experimental results obtained suggest that with a decrease in temperature the sample passes from the paramagnetic state to the spin-glass-like magnetic state characterized by a freezing temperature of T _ f = 4.5 K at the preferred antiferromagnetic exchange coupling in the sample spin system. The chemical pressure variation upon replacement of rare-earth ion R by Yb in the RFeTi_2O_7 system does not change the crystal lattice symmetry and magnetic state.

AbstractThe dispersion of dielectric permittivity in nanocrystalline cellulose–triglycine sulfate composites is studied in the range of frequencies from 10^–3 to 10^6 Hz, at temperatures varying from room temperature to the temperature of phase transition in this composite (54°C), in weak electric fields (1 V cm^–1). Two behaviors for the dielectric dispersion are identified in the studied frequency range: at ultralow frequencies (10^–3–10 Hz), the dispersion is due to Maxwell–Wagner polarization, while at higher frequencies (10–10^6 Hz), the dispersion is due to the movement of domain walls in the embedded triglycine sulfate crystallites. An additional peak in the temperature-dependent profiles of dielectric permittivity is detected at lower temperatures in freshly prepared samples of the considered composite; we associate it with the presence of residual water in these samples.

AbstractThe energy distributions and the properties of the lower vacant electronic states in cobalt and nickel tetraphenylporphyrin complexes CoTPP and NiTPP are studied by X-ray absorption spectroscopy. Quasimolecular analysis of the experimental absorption spectra measured in the region of the 2 p and 1 s ionization thresholds of complexing metal atoms, as well as the 1 s thresholds of ligand atoms (nitrogen and carbon), is based on the comparison of the corresponding spectra with each other and with the spectra of the simplest nickel porphyrin NiP. It has been established that, despite a general similarity of the spectra of nitrogen and carbon in CoTPP and NiTPP, the fine structure of the 2 p and 1 s absorption spectra of cobalt and nickel atoms are radically different. The observed differences in the spectra of cobalt and nickel are associated with the features of the energy distribution of vacant 3 d electron states. The presence in CoTPP of the partially filled valence 3 db _2 g molecular orbital (MO) results in the appearance in the cobalt spectra of a low-energy band, which is absent in the spectrum of nickel in NiTPP and leads to a doublet structure of transitions to b _1 g and e _ g MOs due to the exchange interaction between 3 d electrons in partially filled 3 db _2 g and 3 db _1 g or 3 de _ g MOs. The spectrum of vacant states in CoTPP differs from that in NiTPP also due to the smaller energy distance between 3 db _1 g and e _ g MOs and the different positions of nonbonding MOs with the C2 p character of the porphine ligand.

AbstractA simple numerical method for determining the energy spectrum and wave functions of charge carriers in semiconductor heterostructures (quantum wells, wires, dots, and superlattices) is proposed that employs the effective mass approximation in the general case of multiband kp Hamiltonian corresponding to the Γ point of the Brillouin zone. The method is based on the Fourier transform for structures with periodic potential. For single heterostructures, this periodicity is introduced artificially. In the framework of the proposed approach, the effective matrix Hamiltonian of a heterostructure can be written in two unitarily-equivalent a - and k -representations. As an example, single-band kp models of a heterostructure with one parabolic, triangular, or rectangular quantum well are considered and the influence of interfacial kp corrections on the behavior of envelope functions at sharp heteroboundaries is studied.

AbstractData on the molecular beam epitaxy (MBE) technology, design, and luminescent properties of heterostructures with CdTe/Zn(Mg)(Se)Te quantum dots on InAs(001) substrates are presented. X-ray diffraction has been used to study short-period ZnTe/MgTe/MgSe superlattices used as wide-bandgap barriers in structures with CdTe/ZnTe quantum dots for the effective confinement of holes. It is shown that the design of these superlattices must take into account the replacement of Te atoms by selenium on MgSe/ZnTe and MgTe/MgSe heterointerfaces. Heterostructures with CdTe/Zn(Mg)(Se)Te quantum dots exhibit photoluminescence at temperatures up to 300 K. The spectra of microphotoluminescence at T = 10 K display a set of emission lines from separate CdTe/ZnTe quantum dots, the surface density of which is estimated at ~10^10 cm^−2.

La innovación, producción y comercialización de un producto resulta de la interacción entre una diversidad de actores. Así, el modelo de extensión Hub del programa gubernamental MasAgro busca ser un espacio en el que agricultores, extensionistas, proveedores de insumos, instituciones gubernamentales y de enseñanza e investigación, entre otros, interactúen entre sí con el fin de generar bienestar individual y colectivo a través de la innovación. El objetivo de este trabajo fue analizar las estructuras relacionales dentro de los Hubs. Para tal efecto, se aplicaron entrevistas directas a 457 actores de 10 regiones agroecológicas que conforman los Hubs del sistema maíz en México. Se midieron los indicadores de densidad, cercanía, transitividad y diversidad de relaciones en dos momentos de análisis: línea base y línea final, mediante la metodología de análisis de redes sociales. Una prueba “t” de muestras relacionadas reveló que para los tres primeros indicadores existe diferencia estadística significativa entre momentos analizados (p<0,05), lo que indican que en el Hub se ha gestionado la interacción entre los actores, ubicándolo como un espacio en el que se ha generado estructura local y se ha mantenido el capital relacional, bases del capital social necesario para el desarrollo de procesos de innovación en el sector rural. Estos hallazgos pueden servir a responsables de programas y diseñadores de políticas como una herramienta complementaria de evaluación de estrategias de intervención en el sector.

UTILIZAÇÃO DO SISTEMA DE REALIZAÇÕES GOVERNAMENTAIS POR MUNICÍPIO (RGM) COMO FERRAMENTA GERENCIAL NA SESAB: LIMITES E POTENCIALIDADES
Authors: Lima Talita Aquira dos Santos
Published: February 2018

O Sistema de Realizações Governamentais por Município (RGM) é destinado ao registro mensal das realizações do governo por municípios e se configura como uma ferramenta gerencial disponível nas Secretarias do Estado da Bahia. Considerando o enfoque conceitual dos Triângulos de Governo e de Ferro da gestão, definidos no referencial de Carlos Matus, propõe-se como objetivo identificar os limites e as potencialidades do RGM como ferramenta gerencial para a cobrança e prestação de contas no processo de monitoramento da Secretaria da Saúde (SESAB) no período 2010-2011. Para tanto, realizou-se uma análise documental, descritiva, de caráter exploratório, a partir dos documentos disponíveis na SESAB atinentes ao sistema RGM. As potencialidades identificadas destacam características capazes de garantir a eficácia e qualificação do sistema de cobrança e prestação de contas de uma organização. Entre os limites verificados identificou-se a subutilização do sistema RGM e de suas informações no processo de monitoramento da SESAB. Assim, atendendo as potências apresentadas pelo sistema RGM, torna-se essencial estimular a adesão deste sistema para o acompanhamento dos compromissos e metas assumidos, incorporando-o como parte do processo planejamento em saúde desenvolvido nesta instituição. Palavras-chave: Gerenciamento de informação; Monitoramento; Diretrizes para o Planejamento em Saúde.

Published: February 2018

O objetivo do estudo foi analisar o Custo Total da Saúde Bucal na Atenção Básica no município da Vitória de Santo Antão, Pernambuco, no ano de 2010. O método de apuração de custos utilizado foi o Custeio por Absorção mediante o somatório dos custos com recursos humanos, custos com materiais odontológicos e de pensos com finalidade odontológica, dos custos com manutenção de equipamentos odontológicos e dos custos prediais das unidades de saúde. Calculou-se o percentual das fontes de financiamento (federal, estadual e municipal), o custo médio dos procedimentos odontológicos realizados pelas equipes de saúde bucal e o percentual que o custo médio da saúde bucal representa na atenção básica por habitante. Estabeleceu-se, ainda, o percentual do Custo Total sobre a despesa com a atenção básica em saúde e sobre a despesa total com saúde. O Custo Total foi de R$ 1.340.307,80. Os percentuais e valores de cada Bloco, encontrados, foram: Recursos Humanos – 85,6% (R$ 1.147.048,00); Recursos Materiais – 2,7% (R$ 36.624,53); Manutenção de Equipamentos – 8,5% (R$ 114.000,00) e Custos Prediais – 3,2% (R$ 42.635,27). A participação do Governo Federal no Custo Total foi de 37,5% e a do Governo Municipal de 62,5%, não tendi sido observada participação do Governo Estadual. O Custo Médio do Procedimento foi de R$ 14,88 e Custo Médio da Saúde Bucal da Atenção Básica por habitante foi de R$ 17,61. O Custo Total representou 15,3% da Despesa Total com Atenção Básica e 6,7% da Despesa Total com a função Saúde. Evidencia-se, através deste estudo, que as ações e saúde devem estar em consonância com as necessidades da população, aproveitando o máximo os recursos, evitando-se a má utilização e servindo ao maior número de usuários.
EDUCAÇÃO PERMANENTE EM SAÚDE: CONSTRUÇÕES DE ENFERMEIROS DA ESTRATÉGIA SAÚDE DA FAMÍLIA
Authors: Santos Adilson Ribeiro dos
Published: February 2018

A educação permanente em saúde (EPS) parte do aprendizado significativo, implicando na estruturação do conhecimento a partir da realidade do próprio ambiente de trabalho. Articula aspectos que possibilitam reorientar as práticas dos profissionais de saúde, superando lacunas existentes no campo da formação, visando à melhoria do processo de trabalho em saúde. Trata-se de uma estratégia fundamental para a recomposição da formação, atenção, gestão, formulação de políticas e controle social no setor da saúde. O presente estudo teve como objetivo analisar a participação dos enfermeiros das Unidades de Saúde da Família de Itajuípe, Bahia, nas ações de EPS desenvolvidas no município. Estudo descritivo, exploratório, com abordagem qualitativa, sendo a análise de dados realizada através da análise de conteúdo de Laurence Bardin. Este estudo teve seus aspectos éticos avaliados e acompanhados pelo Comitê de Ética e Pesquisa da Secretaria de Saúde do Estado da Bahia. Os resultados apontam para uma grande associação por parte dos profissionais de saúde da EPS com os processos de educação voltados para as necessidades da população e não para o universo do processo de trabalho em saúde. No contexto em análise, percebe-se que não há uma política local de incentivo à realização das ações de EPS, bem como incentivos para a qualificação e atualização dos profissionais da Atenção Básica.

A incidência cada vez maior de casos de tuberculose e o grande número de abandono do tratamento faz com que essa doença seja um sério problema de saúde pública, acentuado pelo cuidado pouco humanizado que muitas vezes é prestado aos doentes. O presente estudo faz uma revisão integrativa de literatura, com o objetivo de identificar na produção científica brasileira os principais pontos que implicam na prestação de uma assistência pouco humanizada, essencialmente pelo enfermeiro, a pessoas doentes com tuberculose. Para a seleção dos artigos foram utilizadas as bases de dados LILACS, SciELO e BDENF, obtendo-se uma amostra final de 13 artigos. Os resultados foram agrupados em quatro eixos temáticos, que retratam as dificuldades enfrentadas pelos enfermeiros para prestar assistência humanizada a esse grupo. Conclui-se que a enfermagem ainda possui fragilidades na perspectiva do cuidado para pessoas doentes com tuberculose, sendo que essas, muitas vezes, fogem à sua governabilidade.
Assessing Health-Related Quality of Life in Patients With Diabetic Foot Disease: Why Is It Important and How Can We Improve? The 2017 Roger E. Pecoraro Award Lecture
Authors: Wukich Dane K. , Raspovic Katherine M.
Published: February 2018

Patient-reported outcomes (PROs) have become an important subject in the area of diabetes-related foot complications. Self-reported health-related quality of life (HRQOL) surveys can provide a generic measure of overall health (global) and can be disease specific (i.e., diabetes) or even region specific (i.e., lower-extremity function). Analysis of PRO measures utilizing validated instruments allows health care providers to determine whether medical and surgical treatments are providing patients with the highest level of outcome possible and are actually improving HRQOL. The 36-item Short Form (SF-36), EuroQol five-dimension questionnaire (EQ-5D-5L), and Foot and Ankle Ability Measure (FAAM) are examples of commonly used HRQOL surveys. Low HRQOL has been associated with higher rates of hospital admission and mortality in patients with diabetes. Previous studies have demonstrated that patients with diabetes-related foot disease have low self-reported physical quality of life but do not typically report low mental quality of life. The impact of mental quality of life may be underestimated in these patients using the SF-36. In this article, we will discuss several widely used outcome instruments used to measure patient HRQOL and the impact of diabetic foot disease on HRQOL. As health care providers, we must continue to adjust and modify our treatments to achieve the best patient outcomes and associated high quality of life. Assessing PROs will become increasingly important as health care systems transition from a volume-based reimbursement model to a value-based model.
Lobivar Matos: crítica biográfica fronteiriça
Authors: Leite Washington Batista , Nolasco Edgar Cézar
Published: February 2018

O debate sobre a poesia produzida na fronteira e suas práticas artístico-culturais ainda são retiradas de cena no contexto de discursos totalizantes que insistem em não considerar tal produção. Entretanto, com base em uma proposta epistêmica outra e da crítica biográfica fronteiriça, pretendemos trazer uma leitura descolonial outra da poética do intelectual fronteiriço Lobivar Matos. Nesse sentido, propomos ilustrar nossa discussão com suas obras tituladas Areôtorare: poemas boróros (1935) e Sarobá: poemas (1936) escritas na tríplice fronteira (Brasil-Paraguai-Bolívia) ressaltando a contribuição do poeta marginalizado na fronteira e das paisagens transculturadas na sua poética que ilustram os bairros de Corumbá narrados nos livros. Sendo assim, a leitura parte de nosso lócus epistemológico e como a poiesis lobivariana marca uma opção descolonial epistêmica. Para construção de uma discussão teórico-crítica, utilizaremos de um aparato teórico voltados para a perspectiva de contextos epistêmicos descoloniais, como os estudos das sensibilidades biográficas e os estudos pós-coloniais.
Os Huni Kuin entre o regime do seringal e o regime tutelar
Authors: Almeida Maria Ariádina Cidade , Cruz Teresa Almeida
Published: February 2018

Desde fins do século XIX as populações indígenas do Acre foram tratadas como empecilho na extração da borracha, ou “ouro negro” como ficou conhecida. Os exploradores visando expulsar para longe os indígenas de seus próprios territórios e tornar estas terras colocações de seringais, organizavam expedições punitivas chamadas correrias, que consistia na matança de indígenas, com a captura de mulheres e crianças. As populações que sobreviveram a este morticínio permaneceram nos seringais como trabalhadores de um sistema que não apenas explorava a sua mão de obra, como também censurava toda forma de expressão cultural. Assim os indígenas atravessaram dois regimes o seringal, e o regime de tutela das políticas indigenistas, inicialmente como Serviço de Proteção ao Índio (SPI) e depois como Fundação Nacional do Índio (Funai). Na perspectiva do pensamento decolonial este trabalho procura evidenciar a agência indígena na superação da tutela no seringal e nas negociações políticas com a Funai que os Huni Kuin utilizaram para conquistar seu território. As fontes utilizadas são arquivos do Serviço Nacional de Informação (SNI) que pertencem ao projeto Memórias Reveladas.
Un viaje al centro: Cuento y novela
Authors: Merino José María
Published: February 2018

A pesar de adecuarse muy bien a la rapidez de la vida, propia del siglo XXI, la novela corta y el cuento no son géneros que se lean demasiado. La genialidad de estos géneros radica en la brevedad e intensidad con la que se exponen la trama y los personajes, dejando que el lector descubra detalles ocultos entre sus líneas.
Desmemoria, posturas e imposturas en la transición en las primeras obras de Rafael Chirbes
Authors: Thion Soriano-Molla Dolores
Published: February 2018

Las primeras novelas de Rafael Chirbes, En la lucha final (1991) y La buena letra (1992),  han merecido hasta la fecha escasa atención de la crítica. Sin embargo, ya en esos primeros textos Chirbes ofrece una mirada crítica de la Transición desde las intrahistorias de dos universos completamente distintos, uno en torno al mundo de la cultura, otro en un humilde pueblo valenciano. Sus protagonistas hacen las veces de baluartes para poner de manifiesto que la falsedad, la impostura, la desmemoria, las dobleces y las mentiras se convirtieron en claves y modos de estar en el cambio social.
vencidos de la transición en Luz de la memoria
Authors: Laffaille Claire
Published: February 2018

En Luz de la memoria, Lourdes Ortiz utiliza sus propias experiencias vitales y su presente histórico para cuestionar el proceso de la Transición desde sus mismos orígenes. La autora crea una especie de alter ego ficticio,  Enrique García Alonso. Este joven, al igual que ella, formó parte de la generación del 68 y su juventud quedó marcada por un fuerte compromiso político en la lucha marxista-leninista. Al situar la novela en aquel año clave de 1976 y en Madrid, Lourdes Ortiz ofrece una mirada testimonial sobre el proceso que preparó la llegada de la Transición, que no fue tan prometedor ni feliz como se suele decir. El desajuste y las esperanzas frustradas de Enrique en la novela lo ponen de manifiesto. La novelista crea para ello un juicio ficticio entre nuevos vencedores y vencidos en el que la injusticia conduce a Enrique a un estado de crisis personal. Para él, el suicidio y las drogas se convierten en las únicas escapatorias.
Jordi Galceran: la carcajada amarga en el siglo XXI
Authors: Algaba Granero Aroa
Published: February 2018

Jordi Galceran, dramaturgo actual, destaca tanto por su éxito en taquilla como por su calidad literaria. En este artículo se parte del análisis de tres de sus obras (Burundanga, El crédito y El método Grönholm) fijándonos en la sátira social, las estrategias del humor y la deconstrucción de los sistemas de poder a través de la inversión del rol de los personajes manipuladores. Con ello, se pretende ahondar en su perspectiva de la realidad del siglo XXI y diferenciar los límites entre un teatro comercial y de altura literaria.
