conditions.
Modelling of Cavity Nucleation, Early-stage Growth and Sintering in Polycrystal under Creep-fatigue Interaction
Authors: Hu J.-D. , Liu C.-J. , Xuan Fuzhen , Chen Bo
Published: June 2021

A mechanistic based cavitation model that considers nucleation,
early-stage growth and sintering under creep-fatigue interaction is
proposed. The number density of cavities ρ and their evolution
during multi-cycle creep-fatigue loading are predicted. Both the cavity
nucleation and early-stage growth rates, controlled by grain boundary
(GB) sliding mechanism during the tension phase, are formulised as a
function of local normal stress σ. The cavity
sintering that occurs during the compression phase is described as a
function of σ, but the mechanism switches to
the unconstrained GB diffusion. By examining various load waveform
parameters, results provide important insights into experimental design
of studying the creep-dominated cavitation process under creep-fatigue
interaction. First, creep-fatigue test with initial compression will
promote higher ρ value compared to that with initial tension, if
the unbalanced stress hold time in favour of tension is satisfied.
Second, the ρ value does not have a monotonic dependence on
either the compressive hold time or stress level, because of their
competing effect on nucleation and sintering. Third, the optimum value
of stress variation rate exists in terms of obtaining the highest
ρ value due to sintering effect.
AngioVac Suction Embolectomy Using a Roller Pump: Operative Technique
Authors: Shang Michael , Rajabipour Touraj , Vallabhajosyula Prashanth
Published: June 2021

AngioVac suction embolectomy is recommended by the manufacturer to be
performed with a centrifugal pump due to safety considerations. However,
roller head pumps are significantly cheaper to use, and thus may be more
readily available during shortages and in resource poor settings. We
present the technique of Angiovac suction embolectomy being successfully
performed with a roller pump to evacuate a clot-in-transit in the
inferior vena cava and right atrium, along with discussion of important
safety caveats.
Toxicity effects of improved aged refuse on Tagetes patula and rhizosphere microbes
Authors: Hou Fen , Bi Xu , Yuan Ye , Wu Xihui , Du Junjie
Published: June 2021

In this study, we examined the effects of different mass ratios of aged
refuse on Tagetes patula and rhizosphere microbes. The results showed
that chlorophyll content and activities of superoxide dismutase,
catalase, and peroxidase in leaf tissue increased significantly in
plants cultivated in soil:aged refuse mixtures compared with ordinary
soil, whereas levels of malondialdehyde and protein carbonyl decreased
significantly in soil:aged refuse mixtures. Microbial community analysis
revealed that aged refuse is rich in a variety of rhizosphere microbes
that contribute to pollutant degradation, although microbial diversity
was found to be relatively low. Bacterial genera such as
Ferruginibacter, Hymenobacter, unclassified_Gemmataceae,
Longimicrobium, Tychonema CCAP 1459-11B, Gemmatirosa, and
Rubellimicrobium tended to be enriched to a greater extent in ordinary
soil compared with soil:aged refuse mixtures. Correspondingly, bacterial
genera such as Emticicia, Caedibacter, Anaerosalibacter, Tumebacillus,
Patulibacter, Oceanotoga, Dyadobacter, Chloroflexus, and Acidobacteria
bacterium SCN 69-37, Polycyclovorans, tended to be enriched in mixtures
with a higher proportion of aged refuse. Functional prediction analysis
revealed that rhizosphere microbe functions changed markedly following
the addition of aged refuse. These findings indicate that aged refuse
may represent a source of environmental stress for plants and modifies
the dominant bacterial composition of rhizosphere microbes. The
combination of organic or inorganic pollutants, plant physiological
stress responses, and rhizosphere microbial community composition may
have potential cooperative or dynamic equilibrium relationships. With
respect to identifying potential approaches to recycling aged refuse, it
will be necessary to focus on selecting optimal mass ratios of aged
refuse and ordinary soil to control contaminant exposure.

Published: June 2021

A significant percentage of colorectal cancer patients proceeds to
metastatic disease. We hypothesised that mitochondrial DNA (mtDNA)
polymorphisms, generated by the high mtDNA mutation rate of
energy-demanding clonal immune cell expansions and assessable in
peripheral blood, reflect how efficiently systemic immunity impedes
metastasis. We studied 44 rectal cancer patients from a population-based
prospective biomarker study, given curative-intent neoadjuvant radiation
and radical surgery for high-risk tumour stage and followed for
metastatic failure. Blood specimens were sampled at the time of
diagnosis and analysed for the full-length mtDNA sequence, composition
of immune cell subpopulations and damaged serum mtDNA. A high mtDNA
variant number, coexisting with an mtDNA non-H haplogroup, was
associated with low risk of a metastatic event. Abundant mtDNA variants
correlated with proliferating helper T cells and cytotoxic effector T
cells in the circulation. Patients without metastatic progression had
high relative levels of circulating tumour-targeting effector and
natural killer T cells and, of note, the naïve (LAG-3+) helper T cell
population, all inversely correlated with cell-free damaged mtDNA in
serum known to cause antagonising inflammation. The statistical
associations suggested that patient’s constitutional mtDNA manifests the
helper T cell capacity to mount immunity that controls metastatic
susceptibility.

Extraction of Aluminum and Iron from Bauxite: A Unique Closed-Loop Ore Refining Process Utilizing Oxalate Chemistry
Authors: Verma Ankit , Corbin David , Shiflett Mark
Published: June 2021

The Bayer process holds an exclusive status for alumina extraction, but
a massive amount of caustic “red mud” waste is generated. In this
work, three oxalate reagents: potassium hydrogen oxalate
(KHCO), potassium tetraoxalate
(KHCO·HCO),
and oxalic acid (HCO)
were investigated for the Al and Fe extraction process from NIST SRM 600
– Australian Darling range bauxite ore. More than 90% of Al and Fe was
extracted into the aqueous phase in less than 2 h with 0.50 M
CO for all three
reagents. The Fe and Al can be selectively precipitated by hydrolyzing
the aqueous phase. By acidifying the Al and Fe free filtrate, 80% of
the CO can be
precipitated as
KHCO·HCO.
Greater than 90% of the aqueous acid can also be recycled using a
cation exchange resin. The proposed closed-loop process is an
energy-efficient, cost-effective, environmentally-friendly route for
extracting Al and Fe from bauxite ore.
New insights into pathways and kinetic of magnesiothermic reduction of titanium tetrachloride in titanium metallurgy
Authors: Wang Wenhao , Wu Fuzhong
Published: June 2021

There is still no consensus on the reaction pathways and kinetic
modeling of magnesiothermic reduction of titanium tetrachloride, and the
theoretical innovations are required for further research of titanium
metallurgy. We determined efficient reaction pathways via chemical
reaction stoichiometry methodology, and proposed an innovative kinetic
modeling approach of magnesiothermic reduction of titanium
tetrachloride. We explained the reaction pathways by the steps of the
phase change near the gas-liquid interfaces, the homogeneous reaction in
the gas phase, the heterogeneous reduction near the gas-liquid
interfaces, and the like dissolves like in the liquid phase. Net
chemical reaction rate of titanium sponge decreased with decreasing of
titanium tetrachloride feeding rata and with increasing of gauge
pressure. The excellent fitness of the reaction rate constants, f(Δp)
and k(Tin), show that the proposed kinetic equation accuately describes
the reaction mechanism, and is reasonable and acceptable for
magnesiothermic reduction of titanium tetrachloride in titanium
metallurgy.
Process safety assessment of semibatch nitration of naphthalene with mixed acid to 1-nitronaphthalene
Authors: Liang Jun , Ni Lei , Wu Peihong , Yao Hang , Chen Qiang , Fu Gang , Jiang Juncheng
Published: June 2021

In this study, different calorimetric and analytical techniques were
used to evaluate the thermal behaviour of the preparation of
1-nitronaphthalene through the nitration of naphthalene with mixed acid.
Differential scanning calorimetry and adiabatic calorimetry revealed
that 1-nitronaphthalene lacks thermal decomposition characteristics. The
results of reaction calorimetry, high-performance liquid chromatography,
and the density function theory method were combined to analyse the
reaction mechanism. An expanded Stoessel criticality diagram was
developed to evaluate the process safety of the semibatch nitration
reaction. The results revealed a higher degree of risk than that
obtained when using the traditional Stoessel criticality diagram.
Kinetics parameters of the reaction were investigated.
Efficient separation of 1,3-butadiene from C4 hydrocarbons by flexible metal-organic framework with gate-opening effect
Authors: Lu Wang , Huang Hongliang , Hejin Zhu , Yanjiao Chang , Xiangyu Guo , Fan Yang , Zhong Chongli
Published: June 2021

Efficient and economical separation of 1,3-butadiene (C4H6) from C4
hydrocarbons is imperative yet challenging in industrial separation
processes. Herein, a guest-induced flexible Mn-bpdc MOF has been
employed to separate C4H6 from C4 hydrocarbons, including n-butene
(n-C4H8), iso-butene (iso-C4H8), n-butane (n-C4H10) and iso-butane
(iso-C4H10). Significantly, C4H6 can instantaneously induce gate-opening
of Mn-bpdc MOF at 0.13 bar and 298 K, thus significant amounts of C4H6
can be adsorbed, while other C4 hydrocarbons cannot induce the
gate-opening even at 1 bar. The uptake selectivities of Mn-bpdc MOF for
C4H6/n-C4H8 and C4H6/iso-C4H8 are up to 40.0 and 45.0 at 298 K and 1
bar, respectively, both surpassing all the reported adsorbents. In
addition, breakthrough experiments verified that C4H6/n-C4H8,
C4H6/iso-C4H8, C4H6/n-C4H10 and C4H6/iso-C4H10 mixture can be
efficiently separated. More importantly, Mn-bpdc possesses excellent
water stability and outstanding regeneration ability for C4H6
separation, making it a new benchmark for C4H6 purification.
SMALL-SCALE SEAWATER ELECTRODEIONIZATION
Authors: Khoiruddin Khoiruddin , Hakim Ahmad , Bazant Martin , Alkhadra Mohammad , Wenten I. Gede
Published: June 2021

In this work, the performance of electrodeionization (EDI) in seawater
desalination was investigated. EDI stack design and operating parameters
(applied voltage, recovery, and multi-stage process) were examined
during a batch-mode desalination process. The results show that EDI can
achieve 99.5% salt removal in a stack with 4 mm spacer thickness (at 20
V applied voltage, 75% recovery, and 2 mL/s circulation flow rate). A
thinner spacer thickness can enable a higher desalination rate and lower
final solution temperature. Compared to a single-stage process,
two-stage desalination can maintain the salt-removal rate, suppress
reverse salt diffusion, and shorten the desalination time required to
produce similar water quality. The specific energy consumption of EDI is
below 12 kWh/m3 or less than 120 Wh for producing 10 L freshwater.
Considering its simplicity, EDI can be an attractive alternative for
small-scale, decentralized desalination facilities.

Authors: Sosa Zumárraga Martin Alberto
Published: June 2021

El objetivo de esta investigación fue determinar cuáles son las perspectivas de los docentes de la Universidad Autónoma de Campeche (UACAM) en torno a las necesidades de una educación especial inclusiva en dicha casa de estudios. Para ello, se empleó una metodología cualitativa, la cual permitió un primer acercamiento al problema de estudio. Para ello se diseñó una encuesta bajo el formato de la técnica de Likert que incluyó tres dimensiones (social, institucional y didáctica) que fueron construidas con base en 87 ítems que ofrecían cinco opciones de respuesta. Para este trabajo, sin embargo, solo se ofrecen los resultados de 14 ítems significativos que proporcionan información en torno a la perspectiva de los docentes hacia la compresión de la diversidad, así como las necesidades de cambios en la política educativa y de transformación en la práctica docente. En la investigación participaron 11 profesores (tres hombres y nueve mujeres) de la referida institución. De manera general, se puede concluir que si bien los profesores están a favor de iniciativas y cambios normativos que promueven la inclusión y la mejor atención posible a alumnos con NEE, también son conscientes de que trabajar con ellos puede ser difícil. De hecho, muchos señalan que hay confusión en el momento de atender a personas con estas características, por lo que se les dificulta la elaboración de un plan de trabajo.

Coffee is one of the many favorite drinks of Indonesians. In Indonesia there are 2 types of coffee, namely Arabica & Robusta. The classification of coffee beans is usually done in a traditional way & depends on the human senses. However, the human senses are often inconsistent, because it depends on the mental or physical condition in question at that time, and only qualitative measures can be determined. In this study, to classify coffee beans is done by digital image processing. The parameters used are texture analysis using the Gray Level Coocurrence Matrix (GLCM) method with 4 features, namely Energy, Correlation, Homogeneity & Contrast. For feature extraction using a classification algorithm, namely Naïve Bayes, Tree, Support Vector Machine (SVM) and Logistic Regression. The evaluation of the coffee bean classification model uses the following parameters: AUC, F1, CA, precision & recall. The dataset used is 29 images of Arabica coffee beans and 29 images of Robusta beans. To test the accuracy of the model using Cross Validation. The results obtained will be evaluated using the confusion Matrix. Based on the results of testing and evaluation of the model, it is obtained that the SVM method is the best with the value of AUC = 1, CA = 0.983, F1 = 0.983, Precision = 0.983 and Recall = 0.983.

Trans-Pacific Partnership: History of Gradual Development of Regional Integration in the Asia-Pacific Region
Authors: Juntao Wan , Lyubina D. E.
Published: June 2021

The Asia-Pacific region today represents an example of deep regional economic integration. This was largely facilitated by the creation of the TRANS-Pacific Partnership. The undisputed advantages of the Trans-Pacific Partnership are the following: opening markets to all member countries, unifying trade rules, removing obstacles to financial cooperation, creating a favorable investment climate and new guarantees to protect small and medium-sized businesses. The analysis of historical stages of creation and development of a such kind of regional association allows us to trace the evolution of economic integration processes and assess the effectiveness and attractiveness of this type of integration. The study of the specifics of the origin of such a large integration Association in Asia is of interest from the point of view of searching for new “growth points” for integration associations in the Eurasian region and in particular in the post-Soviet space.
The Difficult Path to a Civil Nation: the Experience of Nation-Building in Modern Kazakhstan
Authors: Baranov N. A. , Kok Sevgi
Published: June 2021

Kazakhstan, like most of the multi-ethnic post-Soviet states, in the course of state building, faced the problem of rallying the peoples living in the Republic. Two interrelated projects were being implemented on the political agenda of Kazakhstan: the construction of state institutions and the formation of a civil nation. In a multi-ethnic state, the project of a civil nation is difficult due to the attempts of the titular ethnic group to obtain additional advantages, which causes tension in interethnic relations. The identification of the population, often, occurs by ethnicity, therefore, the policy of civic identity in Kazakhstan is opposed to the “Kazakhization” of language, culture, and social practices. Nevertheless, the process of unification of the nation is successfully developing in the Republic, initiated by the political elite of Kazakhstan. Achievement of national unity was declared a strategic priority in the development of the country. The article analyzes the factors affecting collective identity in the Republic of Kazakhstan: demographic diversity, language policy, state symbols. The article concludes that Kazakhstan is building its statehood based on the domination of the Kazakh ethnic elite, while pursuing a policy of uniting different ethnic groups into a single Kazakh nation.

Development of Foreign Policy Relations Between Japan and Russia: a Retrospective Analysis
Authors: Smirnova О. V.
Published: June 2021

The article provides a retrospective analysis of the development of political relations between Japan and Russia from the middle of the XIX century to the present. The international relations have a nearly three-hundred-year history that reflects various periods of recession and recovery, stability and tension. There was and is a diplomatic struggle of states for financial strength, influence on the world stage, standing up for the national interests in the territorial issue, etc. But despite such moments, these relations did not go beyond the boundaries of “peaceful”. Russia and Japan, as strong players in the Pacific region, have always understood the need for cooperation and have looked for it in political, economic and cultural formats. At the present stage relations between Japan and Russia include different areas: security, economy, culture, science. But the unsigned amicable agreement, which has been delayed for more than 70 years, does not provide ample opportunities for further development of productive mutually beneficial relations. Through the “prehistory” of modern bilateral relations between Russia and Japan, the sequence and nature of relations between the countries is determined. The key aspect that determines the sequence and nature of relations between countries is the historical connection. The material of the article is ranked by time periods (stages), the factors that influenced each of the stages are investigated, and the main problems of the relationships are determined. Special emphasis is placed on the problems of our times, in particular the territorial issue of the Southern Kuril Islands, which were formed historically. Today the relations are based on solving common problems in the economy, security and energy. Within the framework of common interests Japan and Russia are seeking to resolve a long-running dispute. Thus, the article consistently reveals the “prehistory” and the nature of modern bilateral relations. The stages and factors that influenced each of the stages are studied, the corresponding conclusions and forecasts are made.
Features of the US Foreign Policy Towards the Central Asian States
Authors: Kryzhko E. V. , Pashkovsky P. I.
Published: June 2021

The article examines the features of the US foreign policy towards the Central Asian states in the post-bipolar period. The imperatives and constants, as well as the transformation of Washington’s Central Asian policy, have been characterized. It is shown that five Central Asian states have been in the focus of American foreign policy over the past thirty years. In the process of shaping the US foreign policy in Central Asia, the presence of significant reserves of energy and mineral resources in the region was of great importance. Therefore, rivalry for Caspian energy resources and their transportation routes came to the fore. In addition to diversifying transport and logistics flows and supporting American companies, the US energy policy in Central Asia was aimed at preventing the restoration of Russia’s economic and political influence, as well as countering the penetration of China, which is interested in economic cooperation with the countries of the region. During the period under review, the following transformation of mechanisms and means of Washington’s policy in the Central Asian direction was observed: the policy of “exporting democracy”; attempts to “nurture” the pro-American elite; striving to divide states into separate groups with permanent “appointment” of leaders; involvement in a unified military system to combat terrorism; impact on the consciousness of the population in order to destabilize geopolitical rivals; building cooperation on a pragmatic basis due to internal difficulties and external constraints. Central Asian states sympathized with the American course because of their interest in technology and investment. At the same time, these states in every possible way distanced themselves from the impulses of “democratization” from Washington. Kazakhstan was a permanent regional ally of the United States, to which Uzbekistan was striving to join. The second echelon in relations with the American side was occupied by Kyrgyzstan, Tajikistan and Turkmenistan. A feature of the positions of the Central Asian countries is the maximum benefit from cooperation with Washington while building good-neighborly relations with Russia and China, which is in dissonance with the regional imperatives of the United States. In the future, the American strategy in Central Asia will presumably proceed from the expediency of attracting regional allies and stimulating contradictions in order to contain geopolitical rivals in the region.

Impact of the Coronavirus Pandemic on Sino-US Relations
Authors: Jie Zhao
Published: June 2021

This article focuses on the impact of the pandemic coronavirus (COVID-19) on Sino-US relations. It describes Sino-US relations before and after the outbreak of the coronavirus pandemic. Particular attention is paid to the ongoing trade war between the PRC and the US, as well as the development of the information war caused by the politicization of the epidemic. The reasons for the deterioration of Sino-US relations under the influence of the coronavirus are considered. The author highlighted the following factors: US fears about the transition of world economic and political leadership from Washington to Beijing; the disagreement between China and the United States over the anti-epidemic in the framework of multilateral cooperation; problems caused by objectively accelerated changes in the world order. It is concluded that the epidemic plays a limited role in the deterioration of economic and political relations between China and the US. The fundamental reason remains the discrepancy between the unilateralism advocated by the US and multilateralism called for by China.
INFRASTRUCTURE PROJECTS’ ASSESSMENT THROUGH SDG TARGETS: TOWARDS a COMPREHENSIVE FRAMEWORK
Authors: Paul Mansell  , Deney Van Rooyen  , Simon Philbin  , Luca Sabini
Published: June 2021

The achievement of the United Nations’ Sustainable Development Goals (SDGs) is of paramount importance “for the peace and prosperity for people and the planet, now and in the future” (United Nations, 2015; Økland, 2015). Important changes are needed in order to achieve these goals, and infrastructure projects (IP) are critical to facilitate these changes at local and global levels, across health, energy, education, transport, communication and other critical infrastructure needs. However, a gap exists in understanding how SDGs are applied below the global- national levels. In order to increase global and local impact of infrastructure investments, an improved understanding is needed at organisational and infrastructure project levels. In this context, the purpose of this research study is firstly to build on a comprehensive literature review to investigate the existing UN SDG targets in relation to IP, and secondly, to lay a foundation for a comprehensive framework to structure research systematically in this field. This approach can help further our understanding of the topic, thereby providing an important contribution for regulators, policymakers, academia and practitioners on how to align IP to SDGs objectives. This will deliver increased value from infrastructure investments and enable the project management community to generate local impact on global issues, for ‘people and the planet, now and in the future’.

Published: June 2021

Este artigo, situado na área da Linguística Aplicada, analisa os sambas-enredo de 2019 das escolas de samba cariocas Vila Isabel e Mangueira. A análise está afroepistemologicamente baseada na proposta do giro decolonial, especialmente nos conceitos de colonialidade do poder, do saber e do ser, de maneira que a perspectiva afrogênica possa ser um caminho para a construção de saberes desde dentro, suleados. Os resultados classificam os sambas-enredo em categorias opostas: a eurogênica e a afrogênica, indicando que as versões das narrativas contadas podem produzir discursos de silenciamento ou visibilizar o passado histórico através da reafirmação das identidades étnico-raciais.

Authors: Lelles Karina Corrêa , Bittencourt de Carvalho Alexandra
Published: June 2021

Em 2017, a lei nº 13.415 foi publicada orientando mudanças que deveriam ser colocadas em curso no ensino médio no Brasil. O objetivo deste artigo é identificar de que modo participantes de uma audiência pública negociam discursivamente seus próprios interesses. Como resultado, observa-se que há uma dinâmica argumentativa de estudantes e professores que tentam desconstruir a hegemonia. Esta pesquisa tem como proposta teórica-metodológica a análise do discurso crítica, a teoria da mercantilização de Fairclough, e algumas pesquisas sobre políticas educacionais brasileiras. O corpus deste artigo é analisado pelo método sincrônico-diacrônico de análise linguística de Pardo.

Authors: Rios C. dos Santos Frederico
Published: June 2021

O trabalho o objetivo verificar a presença de valores e aspectos dóxicos no discurso político afeitos ao patrimonialismo. Servindo-se do corpus representado pela votação do impeachment de Dilma Rousseff na Câmara dos Deputados, pergunta-se se a menção a cena patrimonialista no discurso é acompanhada, por atração isotópica, de outros elementos ligados ao discurso conservador ou progressista, segundo os parâmetros de Bobbio (2011) e Charaudeau (2016). A pesquisa apontou para o fato de que a maioria dos votantes, ao apresentar um discurso patrimonialista, empregou estratégias retóricas próprias da direita política conservadora, votando massivamente pela saída da ex-presidente.
DECONSTRUCTING THE COLONIALITY OF THE WEST-CENTRIC DEMOCRATIC IMAGINARY
Authors: Baysha Olga
Published: June 2021

Many CDA scholars present the idea of “democracy” as a normative yardstick against which injustices of all kinds and in any type of society can be measured; many also assume there is an inherent opposition between democratization with its advances toward social justice and neoliberal marketization with its array of negative consequences. Analyzing the discourse of democratization in the context of contemporary Ukraine, this paper argues that the issue is more complicated. Neoliberal marketization can go hand-in-hand with the discourse of universal democratization, which only contributes therefore to the perpetuation of neocolonial injustice as manifested in ongoing neoliberal projects.
MÁQUINA DE FAZER O MESMO:
Authors: Bastos de Souza Nathan
Published: June 2021

In this paper we studied the discourses about the reggaeton in newspapers of great virtual circulation in Brazil. The theoretical basis is the concept of stereotype developed by Amossy and Pierrot, Gamarnik and Burke and the analysis methodology is based on the indicative paradigm by Ginzburg. We selected some texts that circulated during 2017 in the newspapers Folha de São de Paulo, O Globo and El País. Our analysis allows us to affirm that reggaeton and its singers are stereotyped because there is a crystallized and previous image that links Latin music to sexuality and it induces to devalue the songs considered of low quality because they are the result of popular culture.
MODALIZAÇÕES EM ARTIGOS DE OPINIÃO COMO REDAÇÃO DE VESTIBULAR
Authors: Barros Eliana Merlin Deganutti de , Belinelli Gabriela Pepis , Striquer Marilúcia dos Santos Domingos
Published: June 2021

O foco deste trabalho é o desenvolvimento de uma pesquisa de natureza qualitativa, de cunho documental, tendo como objeto principal as redações dos candidatos do vestibular da Universidade Estadual do Norte do Paraná (UENP) do ano de 2018. A investigação centra-se na análise dos recursos modalizadores mobilizados pelos candidatos para a produção de textos do gênero “artigo de opinião como redação de vestibular”, tendo como aporte teórico os estudos desenvolvidos por Bronckart (2003), no interior do Interacionismo Sociodiscursivo (ISD), sobre modalização, um dos elementos dos mecanismos enunciativos do texto. O objetivo da pesquisa é analisar como são articuladas as modalizações no processo de argumentação da escrita do artigo de opinião como redação de vestibular, bem como a influência do ato de modalizar o discurso na construção desse gênero. Os resultados apontam uma incidência grande de modalizadores lógicos e deônticos, a inexpressividade de modalizadores apreciativos e a inexistência de modalizadores pragmáticos.
EDUCAÇÃO INTER/MULTICULTURAL NAS PRÁTICAS DO LETRAMENTO ESCOLAR
Authors: Gomes Rosivaldo , Vinicius Ribeiro Puresa Marcus
Published: June 2021

O objetivo deste artigo é discutir como questões de interculturalidade/multiculturalidade são evidenciadas nos discursos de quatro professoras de uma instituição de ensino público, localizada na região norte do Brasil. O estudo, de caráter qualitativo-interpretativista, situa-se no campo da Linguística Aplicada Crítica, tendo sido realizado uma pesquisa de campo com a aplicação de entrevistas semiestruturadas. O corpus é constituído por excertos das respostas discursivas das docentes, tendo sido utilizado a análise crítica do discurso e as concepções de multiculturalismo como dispositivos teórico-analíticos. Os resultados revelam dificuldades e representações discursivas das docentes, tanto de ordem institucional, quanto conceitual e estrutural sobre o ensino de aspectos interculturais, o que demonstrou imperar a perspectiva multicultural assimilacionista no ensino de Língua Portuguesa.

TRANSEXUALIDADE NA ESCOLA: IMPACTOS E DEMANDAS DOS CORPOS MARCADOS PELA SUBVERSÃO
Authors: Café Leonardo da Cunha Mesquita , Monteiro Sales Coroa Maria Luiza
Published: June 2021

A escola é um espaço social em que a diversidade de identidades nem sempre apresenta convivência harmoniosa, especialmente quando grupos minoritários desviantes da hegemonia heteronormativa estão presentes. Estudantes trans carregam as marcas da subversão em seus corpos e sofrem os desdobramentos do discurso transfóbico no ambiente escolar. Sob o aporte teórico-metodológico da ADC (FAIRCLOUGH, 2016; MAGALHÃES et al 2017; RAMALHO e RESENDE, 2016, 2017) e em diálogo com os Estudos de Gênero e Sexualidade (BUTLER, 1993, 2017; LOURO, 2014, 2016; MOITA LOPES, 2008), este artigo busca compreender os impactos da transfobia na vida de alunos/as trans do ensino médio público de Ceilândia/DF, bem como identificar suas demandas e estratégias de enfrentamento através de suas narrativas. Como resultado, notou-se a existência de estratégias de enfrentamento paralelas a ações de resignação e conformidade.
LINGUAGENS, VOZES E DISCURSOS: IDENTIDADES DE UMA TRABALHADORA DOMÉSTICA
Authors: Soares Barbosa de Andrade Franciene , Pereira Conceição Mariney
Published: June 2021

O objetivo deste artigo é investigar marcas identitárias de uma trabalhadora doméstica buscando compreender os motivos que a levaram a assumir uma identidade de analfabeta. Os pressupostos teórico-metodológicos são norteados pela ADC (FAIRCLOUGH, 1999,2016), a Pedagogia Crítica de Freire (1979, 1981) e Hall (2006) e Norton (2000) para discussões acerca de identidades. Uma entrevista semiestruturada e duas narrativas visuais (MELO-PFEIFER, 2015) são os instrumentos para a geração dos dados. A participante assume a identidade de analfabeta, nega suas origens - a roça -, assumindo o modo de falar da cidade como o correto e como um espaço digno de sobrevivência.
IDENTIDADES FEMININAS SILENCIADAS EM ESCOLAS PÚBLICAS DA PERIFERIA DO DISTRITO FEDERAL
Authors: Luiz Flávia Aparecida de Souza , Coroa Maria Luiza M. S.
Published: June 2021

É sob o referencial teórico-metodológico da Análise de Discurso Crítica, embasada principalmente em Fairclough 2001, Pedro, 1998 e Van Dijk, 2008, que se apoia este estudo para analisar marcas de um discurso hegemônico que visa atribuir identidades de subalternidade feminina com práticas de silenciamento. Os fragmentos compõem um corpus maior de dados gerados em uma escola de periferia de Ceilândia, Distrito Federal sob uma ótica qualitativa. É possível dizer que também na escola as práticas e os hábitos da comunidade que a cercam são observados, por ser espaço de convivência e de continuidade das relações pré-estabelecidas fora de seus muros e que a maneira como os estudantes e os demais membros da escola se comportam dentro dela está vinculada diretamente a como vivem lá fora. O que leva alunas ao silenciamento e Ã  descrença de que tal prática será diferente um dia.
TECNOLOGIAS DE INFORMAÇÃO/COMUNICAÇÃO: AGENTES DE LETRAMENTO DE ESTUDANTES COM DEFICIÊNCIA VISUAL
Authors: Azevedo da Silva Jandira , Magalhães Izabel
Published: June 2021

RESUMO
Com a globalização, as pessoas necessitam de informações, as quais vêm crescendo de forma expressiva, mediante a utilização de tecnologias de comunicação e informação (TICs), impactando as maneiras de se relacionar e de aprender. A hipótese levantada neste artigo é a de que essas novas formas de apreensão de conhecimento têm potencial para alargar a visão de mundo e fornecer a autonomia de estudantes com deficiência visual. Na pesquisa de campo e nos dados desta pesquisa, percebemos que em maior ou menor grau, as TICs proporcionam sua independência, auxiliando tanto em sua vida cotidiana, quanto na vida escolar.

Resenha
DISCURSO, IDENTIDADE E DIREITOS REPRODUTIVOS NO SENADO FEDERAL
Authors: Coêlho Santana Jaqueline , Magalhães Izabel
Published: June 2021

Este artigo é dedicado Ã  análise dos discursos das três primeiras audiências públicas interativas sobre a Sugestão nº 15 de 2014, que "regula a interrupção voluntária da gravidez, dentro das doze primeiras semanas de gestação, pelo Sistema Único de Saúde ”“ SUS”. Importa-nos a percepção que as pessoas debatedoras têm das mulheres e de seus corpos nas práticas de interrupção voluntária da gravidez, e em que medida esses discursos são mais ou menos influenciados pela identidade moral das/os debatedoras/es das audiências frente ao tema. Este artigo apoiou-se, sobretudo, no referencial teórico da Análise de Discurso Crítica e recorreu aos modos de operação da ideologia como categorias de análise. Ao focar nas identidades, reforçamos que a forma como uma pessoa representa o mundo e aquilo com o que ela se compromete é parte de como ela se identifica, se relaciona e interage com o outro.
