Effects of Dislocation Density Evolution on Mechanical Behavior of OFHC Copper during High-Speed Machining
Authors: Liu Hongguang , Zhang Jun , Xu Xiang , Qi Yutong , Liu Zhechao , Zhao Wanhua
Published: July 2019

This paper aims at investigating the change in material behavior induced by microstructure evolution during high-speed machining processes. Recently, high-speed machining has attracted quite a lot of interest from researchers due to its high efficiency and surface quality in machining large-scale components. However, the material behavior could change significantly at high-cutting speeds compared to the conventional cutting conditions, including their microstructure and t mechanical response. This is due to the basic physics of material at microscopic levels with high strain, high strain rates, and high temperatures. In this study, the dislocation density-related microstructure evolution process and mechanical behavior of OFHC (Oxygen-free high-conductivity) copper in high-speed machining with speeds ranging from 750 m/min to 3000 m/min are investigated. SEM (Scanning Electron Microscope) and advanced EBSD (Electron Backscattered Diffraction) techniques are used to obtain high-quality images of the microstructures and analyze the dislocation density and grain size evolution with different cutting speeds. Moreover, as material plasticity is induced by the motion of dislocations at micro-scales, a dislocation-density based (DDB) model is applied to predict strain-stress and microstructure information during the cutting process. The distributions of dislocation densities, both statistically stored dislocations (SSDs) and geometrically necessary dislocations (GNDs), are obtained through simulation and experimentation, respectively. The results show that the fluctuation in the cutting forces at high cutting speeds is induced by the specific evolution and distribution of the dislocation density under high strain-rates, and the periodical distribution of sub-surface and fracture behavior during chip separation, which are also found to be influenced by the evolution of the dislocation density.

Sitagliptin is an inhibitor of the enzyme dipeptidyl peptidase-4, used for the treatment of type 2 diabetes mellitus. The crystal structure of active pharmaceutical solids determines their physical and chemical properties. The polymorphism, solvates and hydrates can influence the free energy, thermodynamic parameters, solubility, solid-state stability, processability and dissolution rate, besides directly affecting the bioavailability. Thus, the physicochemical characterization of an active pharmaceutical ingredient is required to guarantee the rational development of new dosage forms. In this context, we describe herein the solid-state characterization of three crystalline forms of sitagliptin: sitagliptin phosphate monohydrate, sitagliptin phosphate anhydrous and sitagliptin base form. The investigation was carried out using differential scanning calorimetry (DSC), thermogravimetry (TG)/derivative thermogravimetry (DTG), spectroscopic techniques, X-ray powder diffraction (XRPD) and morphological analysis by scanning electron microscopy. The thermal analysis revealed that during the dehydration of sitagliptin phosphate monohydrate (Tpeak = 134.43 °C, ΔH = −1.15 J g−1) there is a characteristic crystalline transition event, which alters the physicochemical parameters of the drug, such as the melting point and solubility. The crystalline behavior of sitagliptin base form differs from that of sitagliptin phosphate monohydrate and sitagliptin phosphate anhydrous, mainly with regard to the lower temperature of the fusion event. The melting point (Tpeak) values obtained were 120.29 °C for sitagliptin base form, 206.37 °C for sitagliptin phosphate monohydrate and 214.92 °C for sitagliptin phosphate anhydrous. In relation to the thermal stability, sitagliptin phosphate monohydrate and sitagliptin phosphate anhydrous showed a slight difference; however, both are more thermostable than the base molecule. Therefore, through this study it was possible to establish the most suitable crystalline form of sitagliptin for the development of a safe, effective and appropriate pharmaceutical dosage form.
Integrated Design Approaches for 3D Printed Tissue Scaffolds: Review and Outlook
Authors: Egan Paul F.
Published: July 2019

Emerging 3D printing technologies are enabling the fabrication of complex scaffold structures for diverse medical applications. 3D printing allows controlled material placement for configuring porous tissue scaffolds with tailored properties for desired mechanical stiffness, nutrient transport, and biological growth. However, tuning tissue scaffold functionality requires navigation of a complex design space with numerous trade-offs that require multidisciplinary assessment. Integrated design approaches that encourage iteration and consideration of diverse processes including design configuration, material selection, and simulation models provide a basis for improving design performance. In this review, recent advances in design, fabrication, and assessment of 3D printed tissue scaffolds are investigated with a focus on bone tissue engineering. Bone healing and fusion are examples that demonstrate the needs of integrated design approaches in leveraging new materials and 3D printing processes for specified clinical applications. Current challenges for integrated design are outlined and emphasize directions where new research may lead to significant improvements in personalized medicine and emerging areas in healthcare.

Published: July 2019

Undaria pinnatifida sporophyll (U. pinnatifida) is a major byproduct of U. pinnatifida (a brown algae) processing. Its phenolic constituents, phlorotannins, are of special interest due to their intrinsic ability to precipitate proteins. Herein, a high-temperature extraction procedure was used to isolate these biologically active compounds. The heating temperature, heating time, and extraction solvent (ethanol) concentration were examined with response surface analysis to determine the optimal conditions to achieve the maximum extraction rate. The analysis revealed the optimal conditions to be: 170 °C of heating temperature, 5.2 h of heating time, and 52% ethanol concentration for a yield of 10.7 ± 0.2 mg gallic acid equivalent/g dry weight (GAE/g DW) of sample. Compared to epigallocatechin gallate (EGCG), the extracted phlorotannins displayed higher antioxidant activity on H2O2-induced RAW 264.7 cells with improved efficiency. Furthermore, the compounds exhibited strong anti-inflammatory activity. These findings potentially can be utilized to guide development of novel functional foods and food supplements from sea-originated resources such as brown algae.
Experimental Study on Active Interface Debonding Detection for Rectangular Concrete-Filled Steel Tubes with Surface Wave Measurement
Authors: Xu Bin , Luan Lele , Chen Hongbing , Wang Jiang , Zheng Wenting
Published: July 2019

Concrete-filled steel tube (CFST) members have been widely employed as major structural members carrying axial or vertical loads and the interface bond condition between steel tube and concrete core plays key roles in ensuring the confinement effect of steel tube on concrete core. An effective interface debonding defect detection approach for CFSTs is critical. In this paper, an active interface debonding detection approach using surface wave measurement with a piezoelectric lead zirconate titanate (PZT) patch as sensor mounted on the outer surface of the CFST member excited with a PZT actuator mounted on the identical surface is proposed in order to avoid embedding PZT-based smart aggregates (SAs) in concrete core. In order to validate the feasibility of the proposed approach and to investigate the effect of interface debonding defect on the surface wave measurement, two rectangular CFST specimens with different degrees of interface debonding defects on three internal surfaces are designed and experimentally studied. Surface stress waves excited by the PZT actuator and propagating along the steel tube of the specimens are measured by the PZT sensors with a pitch and catch pattern. Results show that the surface-mounted PZT sensor measurement is sensitive to the existence of interface debonding defect and the interface debonding defect leads to the increase in the voltage amplitude of surface wave measurement. A damage index defined with the surface wave measurement has a linear relationship with the heights of the interface debonding defects.

Published: July 2019

A triboelectric nanogenerator-based self-powered resonant sensor is proposed and investigated. By integrating an inductor and a microswitch with a triboelectric nanogenerator, a new type triboelectric nanogenerator is obtained, the pulse voltage output is converted to an oscillating signal with a very stable modulated resonant frequency, immune to the cross disturbance of contact-related variation (force, frequency, distance) and environmental variation, such as humidity and temperature. This is utilized for non-destructive defect detection. When the coil inductor scans the surface of a specimen with defects, varying resonant frequencies are obtained for different types of defects, showing excellent consistency between the experimental and simulated results. The results demonstrate the potential of the self-powered TENG-based resonant sensor to be a highly stable and sensitive magnetic sensor for the non-destructive defect detection applications.
Modelling and Control of Mechatronics Lines Served by Complex Autonomous Systems

Published: July 2019

The aim of this paper is to reverse an assembly line, to be able to perform disassembly, using two complex autonomous systems (CASs). The disassembly is functioning only in case of quality default identified in the final product. The CASs are wheeled mobile robots (WMRs) equipped with robotic manipulators (RMs), working in parallel or collaboratively. The reversible assembly/disassembly mechatronics line (A/DML) assisted by CASs has a specific typology and is modelled by specialized hybrid instruments belonging to the Petri nets class, precisely synchronized hybrid Petri nets (SHPN). The need of this type of models is justified by the necessity of collaboration between the A/DML and CASs, both having characteristics and physical constraints that should be considered and to make all systems compatible. Firstly, the paper proposes the planning and scheduling of tasks necessary in modelling stage as well as in real time control. Secondly, two different approaches are proposed, related to CASs collaboration: a parallel approach with two CASs have simultaneous actions: one is equipped with robotic manipulator, used for manipulation, and the other is used for transporting. This approach is correlated with industrial A/D manufacturing lines where have to transport and handle weights in a wide range of variation. The other is a collaborative approach, A/DML is served by two CASs used for manipulation and transporting, both having simultaneous movements, following their own trajectories. One will assist the disassembly in even, while the other in odd workstations. The added value of this second approach consists in the optimization of a complete disassembly cycle. Thirdly, it is proposed in the paper the real time control of mechatronics line served by CASs working in parallel, based on the SHPN model. The novelty of the control procedure consists in the use of the synchronization signals, in absence of the visual servoing systems, for a precise positioning of the CASs serving the reversible mechatronics line.
Young Transport Users’ Perception of ICT Solutions Change
Authors: Bąk Monika , Borkowski Przemyslaw
Published: July 2019

The increasing urban population impacts heavily on city sustainability. One of the key sustainability problems in developing cities is an efficient transport system that can meet transport needs at the lowest social cost. The existing body of knowledge tells us that it could be achieved by shifting users to public transport (PT) and increasing occupancy rates of private modes. Against this background we argue that the key tool in ensuring this shift is offered by Information and Communication Technologies (ICTs), especially with the use of smartphones. We posit that young users (i.e., 20–24) can be attracted to public transport through ICTs most effectively. We apply a questionnaire-based field research in Sopot, Poland on a large group of young transport users (i.e., n = 567). What was observed are preferences towards ICT and its potential in encouraging the use of different transport modes. We also survey the differences between car owners and no-owners in relation to their preferences. Our results show that young users prefer ICT solutions but require specific ICT-oriented features. What is most interesting is that access to a private car does not need to be a limiting factor in using public transport if only quality ICT in public transport is offered.
IS DECOLONIZATION OR REVITALIZATION OF EDUCATION NECESSARY IN POST-COLONIAL INDIA? A PHILOSOPHICAL INTROSPECTION
Authors: Valmiki Amita
Published: July 2019

The material is to go back to the work of the master-academicians of British Rule and Post British Rule times. Some asked for radical change in the education system, like Rabindranath Tagore; but people like M. K. Gandhi were moderate and thought of self-sufficient education system. Many other academicians till date are figuring out new educational policies either to ‘decolonize’ or ‘revitalize’ Indian Education System; this being the Indian ‘post-modern deconstruction’ of rigid and orthodox being replaced by progressive and invigorating policies; not giving up the old but ‘revitalizing’ the old in new scenario.

THE TRANSGRESSION OF CONTEMPORARY STRATEGIES OF COLONIALISM
Authors: Yatsenko Olena
Published: July 2019

If we analyze the history of the formation of the European space, then the obvious is the ambiguity and uncertainty of its conceptual foundations. It is difficult to imagine Europe solely as a geographic project. Rather, it is a theoretical-ideological structure, which is the result of the work of prominent thinkers of the past. Or as an operationally effective strategy to implement the policy of colonialism, because the cultural and political component is dominant in defining the European one. Therefore, widespread thoughts on understanding Europe as a form of ideology, myth, discourse practice. Confirmation of this thesis may be the existing discrepancy between nominally articulated provisions and actual events and political decisions. The main content of these concepts form the idea of European values, historical and cultural, philosophical and world-view. However, this phenomenon is rather a reification of the abstraction of pure abstraction. In addition, the ideologues of the Old and New Europe contradict each other. If the traditional world-view paradigm of Europe postulates immutable substantive values, then non-classical post-colonial practice forms the discourse of the unity of diversity. We note only that the motivation for such a unification is the civilization-technological processes of globalization, which forms the axiological basis of a new ideology. That is, the rhetoric of the unity of the various is an integral part of the implementation of the policy of Eurocentrism, since engagement in the European space implies acceptance of the logic of relations and interaction, which are verified by European discourse as proper.

Published: July 2019

The main conditions of the ethics of E. Levinas in their interpretation concerning the practice of educational process presented in the paper of C. Joldersma “A Levinasian Ethics for Education’s Commonplaces: Between Calling and Inspiration” are following: education presumes ethical responsibility, personal involvement of a teacher into caring about the good and wellbeing of a student, education is based on confidence, openness and understanding of ethical asymmetry of the relations of a teacher and a learner. Those principles and values define the contemporary ethos of teaching and learning. On the basis of own research the author analyzes the opinions of Ukrainian teachers about the essence and importance of calling in education. The study also defines the determinative ethical directions of the ethos of learners.
THE POLITICAL AND PHILOSOPHICAL COMPONENT OF THE SERMONS OF ANTHONY RADIVILOVSKY
Authors: Spivak Volodymyr
Published: July 2019

Considering politico-philosophical subjects, the preacher uses the categories belonging to the political world of the Commonwealth, applying to them the specifics of the modern Cossack-Majesty's political system. Before this synthesis is added the image of the Moscow royal power, serving the author in a kind of Orthodox ruler. However, presenting his loyalty to the king, Antony Radivilovsky does not analyse the peculiarities of the political existence of the Moscow court and his subjects, and this symbol can hardly be called an example for imitation. The pseudospectral peculiarity is typical of Ukrainian Baroque ecclesiastics, who showed external affection for imperial power and from time to time represented its diplomatic interests, but did not seek the introduction of Russian order in their own territory and defended the separateness of the Kyiv Metropolis.

História das Religiões seria História ou Ciência da Religião? Uma reflexão sobre questões metodológicas ligadas a essas disciplinas na transição dos anos 1860-1870
Authors: Rey de Carvalho Flávio
Published: July 2019

A História e a Ciência da Religião são disciplinas cujos processos de constituição acadêmica remontam ao século XIX, quando, por volta dos anos 1860, iniciou-se um grande debate em torno da questão metodológica. O presente artigo, a partir do uso da categoria de “ciência normal” de Thomas S. Kuhn, objetiva comparar a concepção de História, com base nas reflexões de Johann Gustav Droysen (1808-1884), com a proposta de Ciência da Religião, formulada por Friedrich Max Müller (1823-1900). Com essa comparação, espera-se ser possível fornecer elementos para se refletir sobre a seguinte questão: do ponto de vista metodológico, estaria a História das Religiões mais ligada à História ou Ciência da Religião?

Este artigo é um capítulo atualizado da minha dissertação de mestrado “O ‘espelho mágico’ do cinema iraniano: uma análise das performances dos "não" atores nos filmes de arte” e tem como objetivo realizar uma leitura do filme Close-up de Abbas Kiarostami enquanto uma obra híbrida, que borra a fronteira entre o documentário e a ficção.Close-up é a recriação de um episódio da vida de Husssein Sabzian, que se fez passar pelo cineasta Mohsen Makhmalbaf e enganou toda uma família. O filme de Kiarostami refaz essa história, assim como registra sua repercussão na vida do rapaz e da família ludibriada.Apesar de ser um filme que já conta com quase vinte anos desde sua realização, Close-up, enquanto objeto de pesquisa, fornece um rico material analítico, pois possibilita uma leitura tanto de seus aspectos ficcionais quanto documentais.A partir do debate que envolve tanto a teoria antropológica quanto a do cinema, discuto as especificidades de cada gênero e como eles se constituem na obra de Kiarostami.

Riparian vegetation has an important role in maintaining water stability, one of which is the river. This study aims to describe the structure of riparian vegetation so that its implications can be seen for the conditions of rainbow arfak habitat on the Nimbai River. The study was conducted in three forest types, namely primary riparia forest, secondary riparia forest and open riparia forest. Sample collection of riparian vegetation was carried out by purposive sampling using sample plots. Plots measuring 2 m x 2 m are used to sample seedling and understorey growth, plots measuring 5 m x 5 m for growth at the stake level, while plots measuring 10 m x 10 m and 20 m x 20 m, for growth of pole and tree levels respectively. The identification results obtained a total of 35 species of understorey and 51 tree-level plants in all three types of riparian forests. Based on the analysis of vegetation structure, it is known that the condition of primary riparia forest and secondary riparian forest still relatively supports the life of arfak rainbow fish compared to open riparian forest. Higher tree level density associated with canopy cover which has implications for the temperature of the water to be colder and less fluctuating, input larger litter into the food chain in the river, and hold suspended particles into the river. Also, the function of riparian vegetation in spawning activities, substrate attaching eggs and nursery habitat for arfak rainbow fish larvae. The results of this study indicate the importance of riparian vegetation structure on the condition of rainbow arfak fish habitat. An understanding of the structure of vegetation is also a basic information for efforts to rehabilitate this endemic fish habitat to maintain the existence of a natural population.

O propósito deste trabalho é apresentar suscintamente o que são os estudos CTS (Ciência, Tecnologia e Sociedade), campo de pesquisa dedicado, entre outras, à análise crítica e interdisciplinar da interação complexa entre ciência, tecnologia e sociedade, questionando a perspectiva que pressupõe uma relação linear entre os mesmos e, por conseguinte, questionando os mitos da neutralidade da ciência e o determinismo tecnológico. Igualmente apresentaremos proposições teóricas do filósofo Andrew Feenberg, em especial sua abordagem sobre a necessidade de “democratização da tecnologia”, pois, conforme Feenberg, a tecnologia é um fenômeno essencialmente social, o que nos possibilita pensar um modelo alternativo de racionalizar a sociedade em direção a formas caracterizadas pela democracia e não pelo controle autoritário.

Published: July 2019

Recibido: 19 de agosto del 2018Aprobado: 20 de septiembre del 2018La investigación tuvo como objetivo, determinar el significado de la paternidad en militares venezolanos. Para ello se realizó una investigación de corte cualitativo, en la que se utilizó una entrevista semi-estructurada para la recolección de la información. Los informantes fueron tres padres que forman parte de la Guardia Nacional Bolivariana de Venezuela con edades comprendidas entre 23 y 28 años de edad. En el análisis se utilizó el método hermenéutico, concluyéndose los padres militares pese a no estar físicamente con sus hijos en todo momento, buscan las alternativas para siempre estar presente en la vida de sus hijos y formar parte de la crianza de estos, usando métodos disciplinarios, separando así su formación militar con la formación de su hijo, lo que llevaría a dejar a un lado los prejuicios y los estereotipos que giran en torno a ellos sobre el hecho de que su trabajo rige su comportamiento frente a todo lo que engloba su vida.

Recibido: 17 de junio de 2018Aprobado: 23 de julio de 2018El objetivo de este estudio fue determinar la frecuencia de infección por rotavirus en niños menores de 5 años que acudieron a los centros de salud urbanos por presentar diarrea aguda. Se realizó una investigación de tipo descriptivo y prospectivo, cuyo análisis y alcance de los resultados estuvieron basados en un estudio de tipo observacional. Se recolectaron datos de antecedentes personales incluyendo vacunación antirotavirus y manifestaciones clínicas mediante una ficha encuesta a 23 pacientes y la detección de rotavirus en heces se realizó mediante inmunoanálisis enzimático directo. Todos los pacientes evaluados resultaron negativos a la infección por Rotavirus. El 86,96 %  tenían el esquema de vacunación anti-rotavirus completo, lo que pudiera explicar la ausencia del virus como causante de la diarrea. Se sugiere continuar con la vigilancia epidemiológica a fin de evitar futuras epidemias de infección por rotavirus.
Atención integral al adulto mayor en Venezuela: un proceso de reflexión desde su recorrido institucional-legal
Authors: Bravo Maika Esther , Lamus Tibisay
Published: July 2019

Recibido: 13 de noviembre de 2018Aprobado: 20 de diciembre de 2018 El artículo tiene como objetivo presentar una revisión en torno a la atención integral ofrecida al adulto mayor desde el marco institucional-legal venezolano, lo cual ha permitido configurar una serie de fases por las cuales ha transitado las políticas públicas: de seguridad social, asistencia social, salud, como vías para ofrecer atención integral a  personas la tercera edad. Esta construcción se ha convertido en un aporte para la ciencia gerontológica como ciencia destinada al estudio del proceso de envejecimiento y la vejez; así como para la carrera de gerontología al identificar, desde la visión de las atoras, elementos claves que han incidido en la atención de la persona mayor en Venezuela. Del mismo modo, en este proceso de revisión se han identificado  la  existencia de una imagen negativa sobre la vejez que son marco de acción en los programas sociales de carácter asistencialista implementados por los gobiernos en el devenir del tiempo.

Narrativas de Rachel de Queiroz: modos de (re)contar, modos de (re)inventar-se
Authors: Moreira Jailma Dos Santos Pedreira
Published: July 2019

Trata-se de uma leitura da textualidade da escritora Rachel de Queiroz, a fim de se observar a relação entre narratividade e subjetividade. Para tanto, enfocaremos seu livro autobiográfico feito em parceria com sua irmã Maria Luiza. Nesse intento, procuraremos observar algumas questões como a escrita que conta com mais de uma mão, a relação com a memória, as formas de (re)invenção de si e de outras mulheres sertanejas, a confluência desse movimento com as representações já feitas e/ou sempre abertas a se refazerem, bem como um certo domínio do mecanismo discursivo da escrita de si. Dessa forma, com um olhar pós-crítico, agenciando estudos culturais feministas, pontos de uma crítica biográfica contemporânea e estudos filosóficos, procuramos discutir tais questões levando em conta o gesto de perlaboração, a noção de sujeito enquanto biografema, as perspectivas temporais, a relação entre saber (contar) de si e cuidar de si, entre ética e estética, entre compromisso teórico intelectual e conhecimento não separado da práxis.
On the duration of nasal vowels in Brazilian Portuguese
Authors: Rothe-Neves Rui , Valentim Hellen
Published: July 2019

Este estudo visou reavaliar os achados de Moraes Wetzels (1992) sobre a duração de vogais nasais distintivas do PB ao ampliar as vogais e os contextos estudados. Segundo a hipótese, uma maior duração da vogal nasal é uma manifestação, no nível da implementação fonética, de uma representação bimoraica e por isso a vogal nasal resultaria mais longa do que as vogais orais e mesmo do que as vogais nasais alofônicas, cuja representação é monomoraica. Foram registradas três repetições de 15 palavras representando cinco contextos diferentes por sujeitos falantes do dialeto de BH. A análise por modelos de efeitos mistos mostrou que a hipótese se refere apenas ao comportamento do [a] antes de plosiva e do [i] antes de fricativa. A hipótese foi também reformulada nos termos da “primazia moraica” (moraic primacy): os falantes mostram maior variação se comparados seu tempo de articulação de segmentos diferentes quando tais segmentos são ocupados por apenas uma mora. Analisaram-se então a variação na duração das vogais [a, i] orais e nasais em contexto seguido por plosiva ou fricativa. Embora vogais sejam mais longas antes de fricativa do que de plosiva, esta diferença aqui só foi atestada nas vogais orais, o que é condizente com a hipótese de que duas moras ocupam mais tempo fonológico restringindo a variação coarticulatória durante a implementação fonética.
INTRINSIC FUNDAMENTAL FREQUENCY RELATED TO LEXICAL STRESS IN THE SPEECH OF PEOPLE WITH PARKINSON'S DISEASE
Authors: Rothe-Neves Rui , Vieira Marcelo
Published: July 2019

Intrinsic fundamental frequency (IF0) refers to a systematic difference in f0 between vowels of different heights in a similar phonetic context: high vowels tend to have higher f0 than lower vowels. Various hypotheses as to the cause of IF0 have been raised, differing mainly on the nature they attribute to the phenomenon: whether it is passive (automatic), resulting from articulatory movements that reach these segments without intending IF0 specifically; or active (controlled), deliberately generated due to reasons of perception or compensatory processes. In this article, we hope to contribute to the debate with f0 data obtained from patients suffering from Parkinson's disease (PD). 631 / a, i / vowels were analysed from recordings of an extract of text read aloud. As a result, IF0 was observed not only in participants from the control group, but also from the PD group, and the trends for participants with dysarthria were no different from those in the control group in the stressed syllable. The fact that we did not observe significant differences between the groups favours the hypothesis that IF0 is automatic. As dysarthric subjects have impaired motor control, the fact that they display IF0 with no difference from the individuals in the control group suggests that the mechanism involved in the phenomenon is similar for both. Our data does not permit us to indicate clearly which biomechanical mechanism would be the best causal explanation for these differences between high and low vowels, but they appear to be consistent with the hypotheses that emphasize the importance of tongue height.
Deixis discursiva y cohésion textual: recursos para la redacción de textos
Authors: Álvarez Bernardo E. Pérez , Di Pierro Carlos González
Published: July 2019

Existe una forma de la deixis discursiva que ha recibido poca atención, y sin embargo puede resultar de gran apoyo en la lingüística aplicada, en particular para la enseñanza de la redacción. Se trata de la dinámica del despliegue textual a partir de unidades de cohesión textual basados en los demostrativos neutros. Para el caso del español, es la situación particular de su uso comosintetizadores de información (deícticos discursivos) que facilitan la continuidad temática y el despliegue textual del universo del discurso. Con fundamento en la pragmática contrastiva y los estudios de cohesión textual, el artículo aborda el uso de los deícticos discursivos como prototípicos de la comunicación oral y de la redacción de inexpertos en el manejo de la escritura, y que pueden servir de apoyo para el monitoreo y la revisión de la redacción, tanto paraescritores de español en lengua materna como para la enseñanza de español como L2. En el artículo se comparan textos orales obtenidos de situaciones comunicativas cotidianas con escritos de estudiantes universitarios, lo que permite describir y analizar las características de la deixis discursiva, para finalmente proponer algunas rutas para mejorar la enseñanza de la escritura enel nivel de la cohesión del texto escrito.
