Factors Associated with Suicidal Ideation, and Attempt Among Cancer Patients in Ayder Comprehensive Specialized Hospital: Cross-Sectional, Mekelle, Ethiopia
Authors: Araya Tesfalem , Gidey Weyni
Published: August 2020

Background:

Cancer patients are at high risk for suicide, particularly, when they are informed about the cancer diagnosis. However, there is a limited study in Ethiopia therefore, assessing suicidal ideation, attempt, and its associated factors are needed for intervention.

Methods:

An institutional-based cross-sectional study was conducted from March to June 2019 at Ayder comprehensive specialized hospital with a total of 297 participants. Suicide module of the World Mental Health (WMH) survey initiative version adopted from the World Health Organization (WHO) and used to assess suicidal ideation and attempt. Binary logistic regression analysis employed to identify factors associated with suicidal ideation and attempt. Odds ratio with 95% CI and P-value <0.05 was applied to identify significantly associated factors.

Results:

The lifetime prevalence of suicidal ideation and the attempt was found to be 27.9% [95%CI (22.3, 31.6)] and 8.4% [95%CI (5.2, 10.3)] respectively. Being female [AOR= 2.23, 95%CI (1.27, 3.92)], stage IV cancer [AOR=2.08, 95%CI(1.47, 3.81)], having depression and anxiety [AOR=2.31, 95%CI(1.24,4.32)], poor social support [AOR=3.70, 95%CI(2.01,6.78)], and level 4 performance status [AOR=3.73, 95%CI(1.71, 8.13)] were the factors associated with lifetime suicidal ideation. While being in level 4, performance status was also significantly associated with suicidal attempt.

Conclusion:

Both suicidal ideation and attempt among cancer patients are high. The suicidal ideation had a statistical association with sex, stage of cancer, having depression and anxiety, social support, and level of performance. Therefore, health education for early screening and treatment for depression and anxiety, and giving social support are crucial for the reduction of suicide.

Authors: Aich Debasish , Mondal Rudra N. , Saha Satyajit , Samanta Pijus K. , Bhunia Amit K. , Kamilya Tapanendu
Published: August 2020

Background:

Lysozyme level in body fluids is a significant indicator of various diseases.
Cheap and simple colorimetric detection of lysozyme, in biological sample, by gold and silver
nanoparticles is a field of interest of nanoparticle research for more than a decade.

Objective:

We report here an attempt to improve the sensitivity part of the colorimetric lysozyme
detection process by using citrate capped gold-silver core-shell nanoparticles without any functionalization.

Methods:

Performance of gold-silver core-shell nanoparticles in determining of lysozyme concentration
in water is done using colorimetric/spectroscopic technique. Gold nanoparticles, silver nanoparticles
and mixed colloidal suspension of gold and silver nanoparticles, for comparison have
also been studied. Selectivity study has been performed through spectroscopic analysis, red-greenblue
colour component analysis and fractal dimension analysis of the nanoparticles interacted with
several low and high isoelectric point proteins.

Results:

Gold-silver core-shell nanoparticles showed higher sensitivity for a wider range of lysozyme
concentration compared to gold and silver nanoparticles prepared by us or reported in literature.
Gold nanoparticles showed higher sensitivity compared to the core-shell nanoparticles, but
for a narrow concentration range of lysozyme. For silver nanoparticles and the mixed nanoparticle
system, both sensitivity and range of determination of lysozyme concentration were much smaller
compared to the core-shell nanoparticles. Core-shell nanoparticles showed better selectivity compared
to gold nanoparticles in identifying aquatic solution of lysozyme from that of other proteins.

Conclusion:

Gold-silver core-shell nanoparticles have higher sensitivity in determining wide range
of lysozyme concentration in water compared to gold and silver nanoparticles reported in literature.

Authors: Kaur Manmeet , Prajapati Suman , Cholia Samneek , Mann Jaskeet S. , Singh Gurpreet
Published: August 2020

Background:

In recent years, the green synthesis of nanoparticles has taken a lead role
over the conventional chemical and physical approach due to its non-toxic, cost-effective parameters
and has found its place in various applications.

Objectives:

The major objectives of this study were to synthesise and characterise the copper nanoparticles
using the rose extract at different set of conditions and analyse these nanoparticles as a
source of dye degradation agent under sunlight.

Methods:

Present study was conducted with the aim to synthesize the copper nanoparticle using
the rose petal extract. The components present in the extract act as the reduction and stabilization
agents for the synthesis of CuNPs. The synthesized nanoparticles were characterized by using UVVIS,
FTIR, XRD and SEM analysis. Photocatalytic degradation of two dyes (Malachite Green and
Carbol fuchsin) was analysed using double beam spectroscopic analysis.

Results:

UV-Vis analysis indicated the presence of a peak at around 630 nm. The FT-IR analysis
indicated the involvement of various biomolecules during the synthesis of nanoparticles. The
structure and the conformation were elucidated using XRD and SEM showed the agglomerated
form of the synthesized nanoparticles with the size range of about 60-90 nm. The synthesised copper
nanoparticles were used for the degradation of malachite green and carbol fuchsin dye using
photocatalytic under sunlight irradiation. UV-Vis spectral analysis indicated that synthesised copper
nanoparticle act more effective in degradation of malachite green (around 95%) whereas carbol
fuchsin showed a maximum degradation by 52% therefore suggesting that CuNPs act as an efficient
photocatalyst in dye degradation.

Conclusion:

The results obtained from this study indicate that rose extract has the potential of synthesis
of copper nanoparticles which is non-toxic and convenient approach as compared to physical
and chemical synthesis. These nanoparticles can be effectively employed as dye decolourisation
agents to treat industrial effluent and prevent environmental pollution.

Authors: Singh Maheshwari K. , Rao Deepthi. N. , Sathish Bedathur A. , Soundarya Sunku P. , Rajagopalan Anusha , Sukumaran Bindhu O.
Published: August 2020

Background:

Proteases play a crucial role in the pharmacological properties of latex producing
plants. Some of them exhibited intervention with fibrinogenolysis and/or fibrinolysis, two crucial
wound healing events.

Objective:

To evaluate wound healing potential of crude and partially purified enzyme from Tabernaemontana
divaricata (stem and latex).

Materials and Methods:

Proteolytic activity, clot inducing/dissolving potential, fibrinogen polymerization,
recalcification time, blood clot lysis and Tricine-SDS PAGE for enzyme treated fibrinogen and
human plasma clot were performed.

Results:

Latex PPE exhibited significant proteolytic activity (115.8 ± 0.3 U/ml) compared to that of the
stem (28.78 ± 0.2 U/ml). Enzyme preparations exhibited temporally spaced clot inducing and subsequent
dissolving properties favoring hemostatic effect, procoagulant effect being dominant and the first
event. Significant reduction in fibrinogen absorbance at 540 nm with time, recalcification time and
human fibrinogenolytic product analysis on Tricine PAGE substantiated procoagulant effect. Disappearance
of Aα and Bβ fibrinopeptides by both stem and latex PPEs in the PAGE was observed. γ subunits
were completely hydrolysed by latex PPE, however, it showed comparative resistance to stem
PPE. Reduction in blood clot weight and fibrin subunit intensity supported thrombolytic property.

Conclusion:

The study provides evidence of the procoagulant and thrombolytic activity associated
with T. divaricata proteases.

Authors: Xie Baocheng , Wang Yi
Published: August 2020

Background:

The non-conductive materials are widely applied in electronics, optics, instrumentation,
aerospace, national defense and civil industry because of their strong wear resistance, high
hardness and good insulation performance. However, it is difficult for traditional machine methods to
process the non-conductive materials. Electrical Discharge Machining (EDM), as a nontraditional advanced
processing technology, is an alternative method for machining the non-conductive materials.
Therefore, the development trend of EDM of non-conductive materials has been paid more and more
attention.

Objective:

To meet the growing processing requirement of processing efficiency and processing quality of EDM of
nonconductive materials, the processing devices and processing methods of EDM of nonconductive materials such as
high-voltage spark machining, auxiliary electrode spark machining and electrolysis spark discharge machining are being
improved continuously.

Methods:

This paper retraces various current representative patents relative to high-voltage spark machining, auxiliary
electrode spark machining and electrolysis spark discharge machining of nonconductive materials.

Results:

Through investigating a large number of patents on EDM of nonconductive materials, the main current existing
problems such as low processing efficiency and poor processing quality are summarized and analyzed. Moreover, the
development tendency of EDM of nonconductive materials in the future is also discussed.

Conclusion:

The optimization of processing devices and processing methods of EDM of nonconductive materials is
conducive to improve processing efficiency and processing quality. More correlative patents will be invented in the future.

that the physical and mechanical properties are affected by the blend ratios.
Caracterización de Necrosoles en el bosque seco tropical en Colombia: un acercamiento desde la geología forense
Authors: Vélez Santiago , Sedov Sergey , Monsalve Timisay , Cardona-Gallo Santiago A. , Quiroz Mary L. , Solleiro-Rebolledo Elizabeth
Published: August 2020

Los Necrosoles son suelos relacionados con entierros cuyas propiedades resultan de las condiciones particulares del entorno de la inhumación. Su caracterización por medio de técnicas de geociencia forense, puede aportar herramientas que maximicen la efectividad de la búsqueda de entierros clandestinos, situación relevante en Latinoamérica. El objetivo de este estudio fue identificar rasgos y procesos pedo-antropogénicos que caracterizan a los Necrosoles, específicamente, se identificaron diferencias micromorfológicas y químicas. Se estudiaron tres perfiles de suelo de cementerios rurales en el cañón del río Cauca, en Colombia, y dos perfiles de la misma zona, fuera de la influencia de los cementerios. La comparación de ambos, perfil dentro vs perfil fuera del cementerio, permitió determinar las variaciones en las propiedades producto del impacto de los entierros. Las muestras de los suelos fueron caracterizadas químicamente y mediante métodos micromorfológicos. Los resultados demuestran que las variaciones entre los suelos de cementerios, respecto a sus referentes naturales, son la presencia de microfragmentos de madera de ataúd y de hueso, minerales con orientaciones paralelas, concentración alta de raíces finas al nivel del entierro y mezclas de agregados pedogénicos entre una matriz no pedogénica. Desde el punto de vista químico, las variaciones observadas fueron la mayor concentración de S, Fe móvil, P, además del incremento en la capacidad de intercambio catiónico del suelo. El presente estudio demostró la utilidad de la micromorfología de tres suelos como herramienta en la confirmación de la presencia de Necrosoles a partir de métodos usados en la arqueología y geociencia forense. Se proponen rasgos diagnósticos modelo para la identificación de entierros clandestinos, en particular para zonas que reúnan condiciones de contextos pedológico, geomorfológico y bioclimático similares y que serán útiles en la geociencia forense.

Estos cambios de organización a nivel de microestructura en Necrosoles, se presentaron de forma escaza, localizada y heterogénea, pero no fragmentados ni dispersos, lo que pudo ser posible por la disposición espacial del entierro en el suelo y a que los restos esqueléticos bien conservados que fueron exhumados cuidadosamente. En este sentido los Necrosoles se diferencian de otros suelos antropogénicos como los Tecnosoles, Urbanozems y suelos arqueológicos, donde los microartefacos son abundantes.

Authors: Ivanenko Irina I. , Lapatina Elena Ya. , Smirnov Pavel I.
Published: August 2020

Introduction. The novelty of the research is driven by the growing environmental contamination with anthropogenic substances, and in the course of accidents and emergency situations, as well as the need to develop the most advanced methods of their elimination. More intensive application of selected micro-organisms, capable of using variable valency chemicals as terminal acceptors, can help to treat wastewater from organic and mineral pollutants.

Materials and methods. The co-authors have performed a review of literature and used analytical equipment to conduct laboratory researches according to standard and advanced methodologies.

Results. The principal results include the restructuring of the treatment facilities operated by Autodetail Open Joint Stock Company. The restructuring consisted in the feeding process change in the currently used biological tower for the feeding to be performed with the help of the fiber carrier and immobilized association of oil oxidizing microorganisms. The association was obtained in the course of earlier laboratory researches. The most active nitrogen-gathering and oil oxidizing cultures, including Rhodococcus erythropoltis, Pseudomonas fluorescens, Arthrobacter tumescens, Pseudomonas rathonis, Azotobacter chroococcum, taken in equal parts, helped to develop a bio-product designated for the decomposition of oil and its components in the aquatic environment. This bio-product was immobilized in respect of the feeding to be performed with the help of the fiber carrier and loaded into the production company’s biological tower which is part of idle wastewater treatment facilities.

Conclusions. In the course of the work performed at the first stage, special cultures were selected for the treatment of water from hydrocarbons of anthropogenic origin. These cultures had nitrogen-fixing properties needed to reduce secondary anthropogenic pollution of the water body. At the second stage, water treatment facilities of Autodetail Open Joint Stock Company were restructured and operation-related results were obtained. They enabled the researchers to make a statement that the biological transformation of pollutions was efficiently applicable to the suspended matter — 99.7 %; oil products — 98.3 %; COD — 89.2 %; nitrogen of ammonium salts — 77.9 %; mineral phosphorus — 53.3 %.

Influence of contact layers on cracking resistance of bending three-layer structures
Authors: Vu Dinh Tho  , Korol Elena A.
Published: August 2020

Introduction. In the present-day construction practice, multilayer building envelopes are applied; their layers are made of concretes having different physical and mechanical characteristics. When different concretes are poured in successive layers, contact layers are formed; their physical and mechanical properties are unlike those of the adjacent layers. The strength and stress-strain characteristics of the contact layers can affect the behaviour of a multilayer structure.

Materials and methods. Numerical and experimental methods are applied to study the stress-train state of such structures exposed to loading. Bending three-layer structural models, having external layers made of strong structural concrete and the middle layer made of low-strength concrete, were applied in the research project. A contact layer is formed in the process of their manufacturing; its geometrical, strength and stress-strain characteristics are simulated in the process of numerical studies.

Results. The co-authors have identified the effects produced by geometrical, strength and stress-strain characteristics of contact layers on the analysis of bending multilayer structures. Design models and a novel method of analysis have been developed for bending multilayer reinforced concrete structures with account taken of the influence of geometrical, strength and stress-strain characteristics of the contact layer. According to the results of numerical calculations, differences between cracking moments can reach 4.3 % or more for three-layer reinforced concrete beams. As for the practical calculations, if the thickness of the contact layer is below 0.4 cm, one can ignore the influence produced by the contact layer on the calculation result.

Conclusions. The results of the research help to identify the rational parameters for the design of multilayer enclosing structures having varying strength reinforced concrete layers interconnected by the monolithic contact layer.
Properties of cement composites based on limestone depending on their granulometric composition
Authors: Samchenko Svetlana V. , Alexandrova Olga V. , Gurkin Anton Yu.
Published: August 2020

Introduction. The use of limestone in cement compositions as an additional cementing agent solves both environmental and economic problems, namely, reduction of construction costs. In this regard, the study of the properties of the granulometric composition and volumetric content of cement composites, containing limestone, becomes increasingly important. The mission of this research is to optimize the properties of composite materials containing Portland cement and limestone by changing the granulometric composition of flour limestone.

Materials and methods. Limestone, having three different Blaine milling fineness values of 250, 300 and 450 m2/kg, was used; its content reached 10, 15, 25 and 35 %. Cement and sand mortars were applied for testing purposes. The influence of the granulometric composition of limestone on the workability and compressive strength of composite cement was determined.

Results. The effect of limestone on the limit shear stress becomes more pronounced when the amount of limestone increases to 25 and 35 %. This is most noticeable for limestone with a high content of fine fractions of 5–20 µm. The use of finely milled limestone increases the initial strength of the composite material. By adding 10 and 15 % of such limestone we can increase the strength by 16–20 %, and supplementary 25–35 % of limestone increases strength by 5–8 %. Strength enhancement is due to the reactivity of limestone and formation of calcium hydrocarbon aluminate 3CaO∙Al2O3∙СаСО3∙12H2O, which promotes formation of the crystal framework of the cement matrix. Additional formation of crystalline hydrates in the initial coagulation structure deteriorates the mortar workability, but increases its strength.

Conclusions. The use of coarse-grained limestone significantly improves mortar workability, while the use of fine-grained limestone increases its content without reducing its strength. The granulometric composition of ground limestone shall be as close as possible to the granulometric composition of cement for the properties of composite materials containing Portland cement and limestone to be optimized.
On maximum-likelihood decoding with circuit-level errors
Authors: Pryadko Leonid P.
Published: August 2020

Error probability distribution associated with a given Clifford measurement circuit is described exactly in terms of the circuit error-equivalence group, or the circuit subsystem code previously introduced by Bacon, Flammia, Harrow, and Shi. This gives a prescription for maximum-likelihood decoding with a given measurement circuit. Marginal distributions for subsets of circuit errors are also analyzed; these generate a family of related asymmetric LDPC codes of varying degeneracy. More generally, such a family is associated with any quantum code. Implications for decoding highly-degenerate quantum codes are discussed.
As trajetórias negras encontram a institucionalidade das políticas públicas contemporâneas: ações voltadas para comunidades quilombolas em São Lourenço do Sul, RS
Authors: Pinheiro Patrícia Dos Santos
Published: August 2020

No contexto contemporâneo brasileiro, entrecruzam-se uma pluralidade de formas substantivas de política, para além daquelas oriundas do Estado. No presente artigo serão abordadas relações estabelecidas a partir da aproximação entre ações estatais efetivadas nos últimos anos que pretensamente abarcariam a diversidade cultural e as trajetórias de comunidades negras do município de São Lourenço do Sul, Rio Grande do Sul, Brasil. Essas comunidades têm se mobilizado na busca por direitos a partir da categoria de “remanescente de comunidade de quilombo”, o que representou uma possibilidade de mudanças nas estruturas de alteridade locais, mas que, no entanto, não apontou para o pleno acesso a direitos. O tema da implementação de políticas habitacionais é abordado neste trabalho a partir do método etnográfico e com uso de perspectivas teóricas que perpassam a etnicidade e o reconhecimento de grupos identitários. Dessas mobilizações, desdobram-se conflitos e negociações entre diferentesatores a partir de articulações que se materializam no cotidiano e se conectam a movimentos reivindicatórios mais amplos, trazendo um questionamento sobre processos de subordinação.

Os pescadores da Lagoa Feia e da Lagoa de Maricá: história, ambiente, memória social e conflitos em torno dos impactos de implementação das políticas públicas de saneamento no estado do Rio de Janeiro
Authors: Valpassos Carlos Abraão Moura , Mello Marco Antonio Da Silva
Published: August 2020

Na primeira metade do século XX, iniciou-se no Brasil um movimento de preceitos higienistas, no qual se combinavam a medicina e a engenharia sanitária. Isso resultou na formulação de uma política pública direcionada ao saneamento do país, iniciada na década de 1930 e implementada, a partir da década de 1940, pelo Departamento Nacional de Obras de Saneamento (DNOS). A Baixada Fluminense foi uma das principais áreas de atuação dessa política que se desdobrou nas ações de dragagens, entulhamento, retificação de rios e córregos, além da abertura sistemática de canais e barras oceânicas, procedimentos esses que provocaram consideráveis impactos nos diversos ecossistemas da região, entre os quais a bacia hidrográfica da Lagoa Feia e o sistema das lagunas de Maricá. O objetivo deste artigo é evidenciar o modo como tais intervenções, no âmbito das políticas públicas do saneamento da baixada litorânea fluminense, feitas pelo DNOS, contribuíram não apenas para afetar profundamente os ecossistemas costeiros, sua gestão e manejo tradicionais, mas, além disso, e sobretudo, para desestabilizar a economia da região, com consequências para as populações dos assentamentos de pescadores, tanto na Lagoa Feia quanto na Lagoa de Maricá.
Memórias, experiências e saberes em contextos de retomada territorial mapuche em El Hoyo, Chubut (Patagônia, Argentina)
Authors: Crespo Carolina
Published: August 2020

Este artigo trata da inter-relação entre práticas de memória, saberes e conformação de subjetividades políticas mapuche no âmbito do processo de recuperação territorial implantado em El Hoyo, província de Chubut, Patagônia, Argentina. Examina, por meio de uma abordagem etnográfica e de trabalho de arquivo, memórias, conhecimentos e experiências mapuches que se colocaram em cena neste processo, continuidades e rupturas, bem como o papel das mulheres indígenas em contextos de luta pelo território e na transmissão de saberes mapuche. O objetivo é demonstrar como esses saberes e memórias se tornaram objetos de reflexão e agenciamento político em múltiplos sentidos. De um lado, desafiaram histórias e silêncios cristalizados e deslocaram categorias e subjetividades assumidas e imputadas. Por outro, configuraram-se como diretrizes a partir das quais foram sendo organizados, definidos, e tornados inteligíveis e legitimados o espaço territorial de resistência e as formas de luta. Finalmente, colocaram em discussão certos modelos hegemônicos associados à “feminilidade” e à “masculinidade”.
Organizações internacionais como aparato de produção simbólica do Estado: o caso da Organização do Tratado de Cooperação Amazônica (OTCA)
Authors: Gonçalves Ferreira Daniela Caruza
Published: August 2020

As organizações internacionais interestatais têm proliferado nas últimas décadas como um instrumento de governo apropriado para tratar questões definidas como de interesse público que atravessam as fronteiras nacionais historicamente estabelecidas. Sua constituição jurídica lhes assegura um lugar privilegiado como sujeitos de uma esfera pública internacional, enquanto a composição de um quadro burocrático próprio, de funcionários públicos internacionais que atuam especialmente através do desenvolvimento de projetos de cooperação, lhes confere caráter eminentemente técnico, autônomo e despolitizado. A partir da análise do processo de constituição e dos modos de operar da Organização do Tratado de Cooperação Amazônica (OTCA), única organização internacional sediada no Brasil, coloco em perspectiva tais imaginários difundidos acerca da forma “organização internacional”. Ao examinar a centralidade da produção discursiva e ritual em seu âmbito, acessada por meio de exame de documentos de caráter público e sigiloso, observo como seus enunciados, que aparentam conter compromissos do Estado para a consecução de finalidades específicas, podem ser entendidos como uma performance da própria capacidade estatal de enunciar domínios sobre territórios e populações, situando-os como parte da disputa pelo poder de definir destinos, sob o nome de “políticas”.
Dinâmicas do depoimento e violência mítica em “Sou eu mais livre, então: diário de um preso político angolano”, de Luaty Beirão
Authors: Laks Daniel
Published: August 2020

Em 2015, o rapper e ativista político angolano Luaty Beirão foi preso por participar de uma sessão de debate sobre um texto de Domingos da Cruz, baseado na obra de Gene Sharp Da Ditadura à Democracia: o Caminho para a Libertação. Ao longo de sua prisão, Beirão escreveu três cadernos relatando suas experiências carcerárias, pensamentos sobre a situação política angolana e letras para músicas expressando suas vivências. Esses diários foram publicados como livro pela editora Tinta da China em 2017. Os objetivos do presente artigo estruturam-se em dois eixos principais. Primeiro, com base nas letras de músicas presentes nos diários do cárcere de Luaty Beirão, visa contemplar a inversão da máxima de Theodor Adorno (2003, p. 7) - “Escrever poesia depois de Auschwitz é um ato de barbárie” - proposta por Slavoj Zizek (2014, p. 19), no livro Violência: “A prosa realista fracassa ali onde a evocação poética da atmosfera insuportável do campo de concentração é bem sucedida” . Segundo, será discutido o conceito de “violência mítica” como fundação de um novo direito, conforme proposto por Walter Benjamin (2011) no ensaio Para uma Crítica da Violência. Assim, o artigo pretende abordar a relação entre regimes autoritários e a escrita poética dos diários do cárcere de Beirão como representativa das dinâmicas do depoimento de eventos extremos, ressaltando as influências da perseguição política sobre o ato de escrever.
“Aviso de gatilho”: efeitos de corpo, testemunho e denúncia
Authors: Azevedo Bocchi Aline Fernandes de , Rodrigues Marília Giselda
Published: August 2020

Este artigo se inscreve no campo da Análise de Discurso e intenta discutir efeitos de corpo, testemunho e denúncia no poema “aviso de gatilho”, de Mariana Rocha Arduini, no qual o sujeito simboliza, por meio da escrita, a experiência da violência sexual. Para tanto, as análises problematizam questões constitutivas de suas condições de produção, como pertencimento, silenciamento e interseccionalidade e versam sobre os rastros de memória que permitem significar o poema como uma escrita de resistência à divisão racial e sexual do trabalho de escritura. Assim, procura-se compreender modos de simbolização da experiência da violência sexual constitutivos do poema como gestos de resistência à produção ideológica de sentidos que hipersexualiza o corpo da mulher negra.
Self news: a ficção que é a sua cara
Authors: El-Jaick Ana Paula Grillo
Published: August 2020

O objetivo deste artigo é investigar, para uma história das ideias linguísticas não teleológica, os conceitos de “pós-verdade” e fake news. A hipótese aventada é a de que já haveria uma protoimagem dessa espécie de ceticismo linguístico contemporâneo na retórica sofística. Para fundamentar esse gesto de leitura, faz-se uma análise de uma fake news com base na perspectiva foucaultiana de linguagem, sobretudo aquela expressa em A ordem do discurso. Como o campo da história das ideias linguísticas é, por definição, um empreendimento interdisciplinar, a presente investigação é uma análise do discurso que problematiza as “disciplinas” assim chamadas de Linguística, Literatura e Filosofia da Linguagem, uma vez que coloca em questão o discurso “verdadeiro”/”falso”, a “ficção” e a “não ficção”. Por fim, há a defesa da tese de que, se há algum embrião da nova “era da pós-verdade” na aAntiguidade clássica, na contemporaneidade há um cinismo e um ultranarcisismo que ressignificam tal ideia linguística. Daí a proposta desse artigo de trazer o conceito self news para contemplar essa (nova?) ideia linguística contemporânea.
A absolvição do autor nos estudos narrativos contemporâneos
Authors: Oliveira Raquel Trentin
Published: August 2020

Este artigo discute o trajeto do conceito de autor nos estudos narrativos, desde a abordagem mais restritiva da narratologia clássica ou estruturalista até a abordagem mais aberta e dinâmica das narratologias pós-clássicas, destacando algumas concepções paradigmáticas nesse trajeto. Os estudos narrativos mais recentes, que expandem os fundamentos epistemológicos e metodológicos da narratologia clássica, valorizando, entre outros aspectos, problemas éticos e a negociação dialógica das significações implicada no processo de leitura, oferecem instrumentos analíticos para ressignificar o papel e a imagem do autor na atividade de interpretação da narrativa.
