The object of research is the process of functioning of organizations at different stages of the life cycle (LC). Papers addressing the management of organizations ignore the need for them to acquire competence to successfully solve the tasks of each stage. This directed the research to the definition of priority management tasks, determined by the nature of activity at different stages of LC, and the competencies necessary for their solution. The directions of the transformation of the structure of organizational competence due to the change in the frequency of reference by heads of organizations to its members in the process of solving tasks have been determined. The importance of functional and basic component competencies at the birth stage was noted (36.7 and 38.7 % of reference in the total number). The increase in the frequency of reference to the competencies of synergistic, key, and strategic components (3.4; 2.2; 1.66 times) at the stage of intensive growth is explained by the organization gaining authority in business circles, the possibility of its use for lobbying organizational interests. Among the competences at the stage of maturity, representatives of the synergistic and functional components prevail – the increase in the frequency of reference by 1.44 and 1.1 times, respectively. The share of reference to the competences of the basic component is also high (40 %). At the stage of decline, functional and basic competencies remained important (36.9 and 39.5 %), in particular, the competencies of managers in ensuring the most painless liquidation of the organization.
A distinctive feature of the study is the addition of the procedure for determining the stage of LC with a list of priority tasks and the competencies necessary for their solution. This made it possible to understand the directions of the transformation of competence, to identify the need for the development of competences due to the organization's position on the life cycle curve or its change

Authors: Petrenko Olexandr , Pererva Viktor , Maslov Viktor
Published: May 2024

The object of this study is the ST-25 Hall thruster with limited discharge power, no more than 200 W, designed by Flight Control LLC (Ukraine). The problem that was solved in the current paper was to determine the effect of residual gas pressure in vacuum chambers on the operating parameters of the Hall thruster. To solve this task, the operating parameters of the ST-25 thruster were determined, which was tested in three vacuum chambers with different sizes of residual pressure. As a result of the laboratory study into the operating parameters of the ST-25 thruster, the volt-ampere characteristics of the engine discharge at fixed values of the working gas (xenon) flow rate were obtained. The dependences of the engine thrust on the mass flow rate of the working gas at fixed values of the discharge voltage were derived. Based on the experimental data, the dependences of the specific impulse of the engine anode unit on the discharge voltage, as well as the dependence of efficiency of the engine anode unit on the discharge voltage were calculated. The studies showed that when the residual pressure in the vacuum chamber is reduced by 2–3 times, the operating parameters of the engine increase by 15–20 %. Such a reduction in residual pressure increases thrust by 25–40 %. Special feature of the results is the determination of threshold values of residual gas pressure in vacuum chambers during experimental studies, in which the operating parameters of the Hall thruster are similar to its operating parameters under space conditions. This work’s findings could be used in practice when conducting experimental studies of electric rocket engines, when it is necessary to estimate the operating parameters of Hall thrusters that will be obtained under actual space conditions

In theoretical mechanics, the equilibrium of a flexible, inextensible thread is considered, to which the tension force of its ends and the distributed force of weight along the length of its arc are applied. An unsolved problem is finding the shape of the thread under the action of other distributed forces. This study has considered the equilibrium of a completely flexible thread, to which, in addition to this force, a transverse distributed force is applied. A sail serves as an example. Wind of equal intensity in the plane of the orthogonal section of the sail can be considered a distributed force. The sail can be cut into narrow strips with the same shape of the curves of the cross-section, which are equal to the cross-section of the sail as a whole. The theory of flexible thread is applied in the current study. The task is reduced to finding the curve of the cross-section of the sail.
The object of research is the formation of a cylindrical surface from a flexible thread under the action of distributed forces applied to it.
An important characteristic of the shape of a flexible thread is its curvature. Its dependence on the length of the arc was found and it was established that the found curve is a chain line (catenary). This is the feature of the current research and its distinguishing characteristics. The significance of the results stems from the derived analytical dependences, according to which the change in the ratio between the distributed forces acting on the flexible thread deforms it, but it retains the shape of the catenary. At the same time, the angle of deviation of its axis of symmetry from the vertical changes. In the absence of a horizontal distributed force and the presence of only a distributed force of weight, the axis of symmetry of the chain line is directed vertically – at an angle of 90° to the horizontal. If they are equal, this angle is 45°. Scope of application includes structures with stretched supporting wires, conveyor belts, flexible suspended ceilings, the shape of which can be calculated by using our results

The object of this study is the process of detecting stealth aerial vehicles by a network of two small-sized radars with decentralized signal processing. The main hypothesis of the study assumed that combining two small-sized radars into a network could improve the quality of detection of stealth aerial vehicles with decentralized signal processing.
The improved method for detecting a stealth aerial vehicle by a network of two small-sized radars with decentralized processing, unlike the known ones, provides for the following:
– each radar emits its own probing signal;
– each radar receives only its own signal;
– coordinated filtering in the reception system of each radar of its signal;
– quadratic detection of its signal in each radar;
– finding the sum of detected signals in each radar at the output of its matched filter;
– preliminary detection of the signal is carried out by each radar separately;
– in each range element, the signal is compared with the threshold level;
– when the threshold level in the range element is exceeded, such range element is assigned a value of one, otherwise – zero;
– the sequence of zeros and ones obtained in this way in each radar of the network is transmitted to the central processing point;
– at the central processing point, a decision is made about the presence or absence of a stealth aerial vehicle in the range element. Such a decision is made based on the results of the combined processing of binary sequences coming from the radars according to the "k out of m" criterion.
It was established that when detecting a stealth aerial vehicle by a network of two small-sized radars, decentralized information processing provides a higher value of the conditional probability of correct detection, by (19–26) % on average

Published: May 2024

The object of this study is project management under the changing conditions of the modern economy. The way the top management of the company affects the implementation of projects in various sectors and branches of production is an issue related to business development in general. An increasing number of enterprises use project tools to adjust production processes. To this end, in particular, it is advisable to use administrative management tools against the background of its improvement at the level of the company's management.
The logic of this study construction implies an emphasis on theoretical and experimental components. The theoretical foundations of the study include the identification of administrative management tools. The coverage of the experimental part is devoted to multifactorial regression analysis (the coefficient of determination is 0.715) of the influence of administrative management factors on the effectiveness of projects based on construction excavations.
The interpretation of the research data confirms that the administrative management toolkit could be optimally used to establish high-quality project management.
Based on the study of aspects of the relationship between administrative management and project management, the definition of administrative management and the project management system at modern enterprises is proposed.
The study concluded that it is necessary to use those levers that are common in companies of industrialized countries of the world. Europe's experience will be useful in spreading the practice of project management in enterprises of countries with transition economies. The results of the research could be used at enterprises of various sectors of industry, agriculture, and the service domain, in particular at construction enterprises that were chosen as the object of research
Construction of mathematical and computer models for calculating contact characteristics of interaction between a rigid punch and an elastic half-space
Authors: Zaytseva Tetyana , Zhushman Vladyslav
Published: May 2024

The subject of this study is a punch-elastic half-space system under compressive force. The paper solves the problem of determining contact stresses and displacements. The content of results is the constructed models and the assessment of their adequacy.
This work considers the problem of pressing a rigid plane double-connected punch on a homogeneous and isotropic elastic half-space. To obtain an analytical solution, a variant of the perturbation method based on the expansion of the potential of a simple layer distributed over a double-connected region by a small parameter was applied. The problem of pressing a flat punch in the form of a non-circular ring is reduced to a sequence of problems for a punch in the form of a circular ring. This allows us to use a known solution for a circular ring.
Finite element models were built using ANSYS. A group of models was constructed to take into account possible damage in the event that the punch-elastic half-space system is exposed to difficult natural conditions or an aggressive environment during a certain time of modeling. A database was formed for the purpose of further transferring it to CLIPS. Sets of rules and knowledge were compiled.
A generalizing algorithm was developed for the problems of constructing and analyzing mathematical and computer models of contact interaction between a rigid cylindrical punch with a flat double-connected base with an elastic half-space under the action of a compressive force. The problem of determining the geometric shape of the cross-section of an annular punch in the plan for the punch-elastic half-space system was solved for the case when the contact zone is not known in advance. The devised approach could be employed in engineering calculations for strength and durability

Published: May 2024

Supercritical CO2 (S-CO2) cycles have found applications in power generation and can achieve high efficiency in a wide range of temperatures and pressures. The Redlich-Kwong-Aungier real gas equation of state is used to describe the thermodynamic properties of the CO2 working fluid. The main problem in its application lies in modeling the phase transition between different states and the region near the critical point of the working fluid.
The object of the study is the working process in a centrifugal compressor located in the compression loop with the CO2 working fluid. The proposed mathematical model of the modified Redlich-Kwong-Aungier equation of state allows for a first-order phase transition from the liquid to the supercritical region even near the critical point. A scaling factor was added to the modified equation of state, significantly reducing the error in pressure determination in a wide range of temperatures compared to the original equation of state. The proposed mathematical model can be applied in the pure liquid region, limited to the temperature range from 220 K to 300 K.
The mathematical model was used to solve the 3D gasdynamic problem, specifically to determine the thermodynamic and kinematic properties of the flow in a centrifugal compressor in a wide range of operating modes. A comparison of the calculation results with experimental data from the Sandia National Laboratories (USA) report was conducted. A satisfactory agreement of the results at the design point of the compressor characteristic was obtained (less than 5 % discrepancy).
Due to the simplicity of the equation of state and the small number (seven) of empirical coefficients, the obtained mathematical model can be used for practical CFD tasks without significant computational time costs.

Published: May 2024

The article deals with the indirect methods for calculating the temperature of asynchronous generators with the introduction of a pulse component in the power supply circuit of the stator windings of asynchronous generators with squirrel-cage rotor. The relevance of this issue is determined by the need to improve asynchronous energy converters to increase their reliability and safety.
The object of the study is an asynchronous generator with squirrel-cage rotor, which consume 40 % of the total electricity generated, and are the most affordable. One of the dangerous modes of asynchronous generators is their overheating as a result of increased currents and temperatures.
The thermal protection of the stator winding of asynchronous generators relies primarily on measuring or determining the winding temperature.
An indirect method for determining temperature based on measuring the resistance of the stator of an asynchronous generator with squirrel-cage rotor is proposed. The method is based on superimposing pulse signals of small amplitude and high frequency of 600 Hz on an alternating sinusoidal voltage with a frequency of 50 Hz. A simulation model for a 3 kW asynchronous generator has been developed. There were given the simulation results. The estimated values of the active resistances of the stator can be used to indirectly determine the temperature of the windings in thermal protection devices of asynchronous generators, as well as for control, monitoring and diagnostics of the technical condition. The research results confirm the possibility of indirect temperature determination and the creation of a thermal protection system for asynchronous energy converters based on the use of estimation methods.

Published: May 2024

The coastal areas of Quang Binh province play a crucial role not only in the economic and tourism development of the coastal province but also in the overall development of the Northern Central region. Therefore, monitoring and forecasting seawater quality in this region is vital. However, the water quality condition assessment faces many limitations due to the lack of measured data and the complication of numerical models. Meanwhile, the artificial intelligence model for simulating and predicting water quality has been widely applied due to its timely and reliable calculating abilities. This research has piloted the prediction of some water pollution parameters on the coast of Quang Binh province using an artificial neural network (ANN) model. This presents a novel approach to identifying implicit relationships between variables based on data analysis techniques via ANN. An ANN model was built to analyze the measured environmental time series data at Dong Hoi station, Quang Binh province, from 2002 to 2022. The calculation results of the training (70% of the data set, NSE: 0.81) and testing (the rest 30% of the data set, NSE: 0.5) of the model have satisfied the total coliform parameter, indicating the promise of applying the ANN model for water quality prediction.

Authors: Quy Vu Phan , Huu Dinh Tran , Thuy Duong Nguyen
Published: May 2024

Male infertility is a prevalent global concern, impacting an estimated 7% of the male population. Many single nucleotide polymorphisms (SNPs) linked to idiopathic male infertility have been discovered since the 1990s, including two intronic SNPs of the estrogen receptor α gene (ESR1), namely rs9340799 and rs2234693. However, the associations of the two SNPs with male infertility have yielded inconsistent results across different populations. In this study, we aimed to assess the association of ESR1 rs9340799 and ESR1 rs2234693 with male infertility in a cohort of Vietnamese individuals consisting of 154 fertile men and 146 infertile men. Genotyping ESR1 rs9340799 and ESR1 rs2234693 for 300 samples was performed using polymerase chain reaction-restriction fragment length polymorphism (PCR - RFLP). The frequencies of genotypes and alleles were analyzed using bioinformatic tools. The genotype distributions of ESR1 rs9340799 and ESR1 rs2234693 followed Hardy-Weinberg equilibrium, but no association of the two SNPs with male infertility was established (p > 0.05) in the additive, dominant, recessive, and allele models. Notably, the haplotype analysis revealed a strong association between the haplotype GT and a decreased risk of male infertility (OR = 0.226; 95% CI = 0.106 - 0.484; p < 0.001). The findings provide additional knowledge about the roles of single nucleotide polymorphisms in male infertility in the Vietnamese population.
Three rare dioecious Caenorhabditis nematode species (C. Tribulationis, C. Yunquensis, and C. Zanzibari) do not live in the same habitats
Authors: Tho Son Le , Thu Hang Nguyen Thi , Thu Nguyen Thi
Published: May 2024

The Caenorhabditis nematodes are among the best model systems for studies verifying the molecular-to-phenomenon consequences at different magnitudes. Hundreds of strains within nearly 60 species have been found in the wild and used for studies of evolution. However, the insights of evolution could be uncovered deeper when more Caenorhabditis isolates are gained and accessible. Unfortunately, the effort to isolate wild-type strains is not efficient in the habitats where the Caenorhabditis nematodes do not naturally distribute. In contrast, we surveyed many samples in various locations and revealed the presence of Caenorhabditis nematodes, which had already been seen globally. This suggests that rarer nematode decedents may live in the same habitats. In this research, we report the current isolations and the identifications of three Caenorhabditis species (C. tribulationis, C. yunquensis, and C. zanzibari) with low frequencies of discovery in the wild. Molecularly, they are highly similar to a few previous relatives from other territories.
Mutation of rsmC gene from Serratia marcescens QBN using CRISPR-Cas9 to enhance prodigiosin synthesis

Published: May 2024

Prodigiosin is a bright red pigment, which is produced by various gram-negative and gram positive bacteria include S. marcescens, Hahella chejuensis, Vibrio psychroerythrus, Streptomyces coelicolor and many marine bacteria such as Pseudomonas sp, Vibrio sp. Prodigiosin has garnered considerable interest among the scientific community due to its immunosuppressive and anticancer properties against various drug-resistant cancer cell lines. In this study, we utilized the biosynthetic pathway of prodigiosin (Pg), using CRISPR/Cas9 gene editing techniques to eliminate the gene inhibiting Pg synthesis, known as rsmC, aiming to enhance the ability to synthesize Pg from S. marcescens strains. The rsmC gene of S. marcescens QBN was randomly mutated using the CRISPR-Cas9 system with the pCasPA vector (containing Cas9) and pCRISPR (carrying the spacer segment and sgRNA synthesis). A 20-nucleotide spacer segment was selected on rsmCpreceding the TGG triplet at the 3' end (PAM, the recognition site of Cas9) and inserted into pCRISPR between two BsaI sites. Following the binding of sgRNA to Cas9, mutations occurred in the nucleotides of the rsmC gene, resulting in the cleavage of the double-stranded DNA at the targeted site. A sequence homologous to the rsmC gene, lacking 100 nucleotides, was introduced into the cell and will involve the cleaved DNA's repair mechanism. The mutated rsmC strain of S. marcescens QBN synthesized Pg at 216 - 231 mg/L, higher than the original strain (180 mg/L). Furthermore, HPLC results and 1H spectral analysis showed that the synthesized red pigment from the mutated strain S. marcescens QBN was prodigiosin. These findings provide a basis for further improving the productivity of Pg synthesis in the S. marcescens QBN strain and serve as a basis for editing genes in other microorganisms using the CRISPR-Cas9 system.

The article analyzes the causes, implementation strategy, and results of vaccine diplomacy of the People’s Republic of China and the Russian Federation in Central and Eastern Europe. In particular, the activities of China and Russia in Serbia, Hungary, Northern Macedonia, Montenegro, Bosnia and Herzegovina, Albania, Moldova, Belarus, and Ukraine are covered. The main directions, tools, and consequences of the activation of the two states in the region are outlined. The article underlines that China is expanding its strategic goals according to the One Belt One Road Initiative through the so-called Health Silk Road, providing a vaccine to low- and middle-income countries. The goals of the Russian Federation are established more in the geopolitical and political spheres. Russia seeks to reduce the influence of the EU and the US in the CEE region from political, economic, and security perspectives. China and Russia are both allies and competitors. The two countries are trying to gain additional leverage in the CEE region by means of political lobbying, investment, finance, propaganda, Euroscepticism, public opinion manipulation, and soft power. For some time, the shortage of medicine for vaccination, which was caused by giving priority to the population of vaccine-producing countries, contributed to a rather increased activity of the PRC and the Russian Federation in the implementation of the strategy of gaining image benefits.

Published: May 2024

ABSTRACT This study systematically reviews Brazil's organizational creativity literature and discusses emerging themes that will enable the field's continued development. Creativity is related to developing and enhancing ideas and has been investigated over a broad scope of perspectives. A search was conducted in the SPELL electronic library from a gap identified in literature review research in the country. The results showed that the field is still young and endogenous, with few partnerships between authors. However, it was also evidenced that the research has gained strength in the last decade, with a tendency to grow. The most investigated themes were organizational creativity and team creativity. In addition, emerging themes such as sociomateriality, artificial intelligence, distributed creativity, polyarchism and ambidexterity, which can leverage the impact of organizational creativity research, are discussed. Finally, specific conditions of the Brazilian context are discussed and presented as a way for national research to contribute for theories of creativity in organizations. We used only the Scientific Periodics Electronic Library (SPELL). Thus, articles from national journals not part of this database were excluded. Further studies may expand research bases and focus on how the themes identified in the article impact organizational creativity and performance.

Published: May 2024

RESUMO Diante do crescente debate acadêmico e organizacional sobre gênero, voltamos nosso olhar neste artigo para os sistemas de cotas de participação feminina que vêm sendo adotados em diferentes países. Neste contexto, questionamos a afinidade desses sistemas com a efetiva igualdade de gênero reivindicada pelos movimentos feministas. A partir disso, o objetivo deste ensaio teórico é refletir sobre as cotas de gênero nas organizações à luz dos ensinamentos da abordagem feminista de Nancy Fraser, que possui um compromisso com a justiça social e a emancipação da mulher. A articulação teórica revela que as cotas de gênero estão inseridas em estruturas amparadas por ideais neoliberais e, portanto, não são capazes de romper com a opressão de gênero.

ABSTRACT With the COVID-19 pandemic, elective orthopedic surgeries were interrupted in most healthcare services. This leads to impacts on the quality of life, as well as on the emotional, professional, and financial situation of patient athletes who had their surgical treatment postponed. Objective: To evaluate clinical, emotional, and professional impacts on athletes who had their knee surgery postponed. Methods: This study included 21 patients who were diagnosed with knee injuries and were on a surgical waiting list. Participants answered a questionnaire with socioeconomic questions, activity level (amateur/professional), diagnosis, proposed surgery, and questions about anxiety regarding the postponement and uncertainty of performing the surgery, worsening symptoms, and psychological status in general. Results: The most prevalent diagnosis was anterior cruciate ligament injury (81%). Moreover, 42.9% of patients reported being highly anxious about the date of surgery, with 23.8% being highly anxious about the uncertainty of surgery. There was a direct positive correlation (r = 0.418), indicating a higher level of anxiety in patients who faced greater financial impact. Conclusion: The indefinite postponement of surgeries had a great impact on anxiety levels and surgery uncertainty of patients awaiting surgery. Level of Evidence III, Transversal Study.

ABSTRACT Objective: To determine the epidemiological profile of patients treated at a philanthropic hospital specialized in Orthopedics and Traumatology, located in a significant urban center, and evaluate the efficacy of initial empirical antibiotic treatment. Methods: Patients diagnosed with hand infections from September 2020 to September 2022 were included, excluding cases related to open fractures or post-surgical infections and those with incomplete medical records. The chi-square test was performed using STATISTICA ® software to correlate various variables. Results: A total of 34 patients participated, including 24 men and 10 women, with an average age of 41.9 years. Most male patients had Diabetes Mellitus, HIV, and drug addiction, and they resided in urban areas. Half of the patients did not report any apparent trauma. The most common infectious agent was Staphylococcus aureus*. Nearly 62% of patients required a change in the initial antibiotic regimen, with Penicillin being the most frequently substituted medication. Beta-lactam antibiotics and Quinolones were the most effective. Conclusion: These results suggest the importance of carefully evaluating the epidemiological profile of patients with acute hand infections and improving initial empirical treatment to ensure appropriate and effective therapy. Level of Evidence IV, Cross-Sectional Observational Study.
Ficção literária e mímesis em Luiz Costa Lima
Authors: Caminha Adelaide Barros
Published: May 2024

Resumo Na revisão da mímesis proposta por Luiz Costa Lima desde 1980, certa modalidade de ficção literária parece ocupar um lugar central. Atentando para sua tentativa de delimitá-la através do mecanismo da verossimilhança, este artigo propõe um aprofundamento de sua própria sugestão, desenvolvendo-a através da articulação com as peças de seu tabuleiro teórico e do diálogo mantido com as contribuições de Wolfgang Iser. Com isto, objetivamos evidenciar o duplo papel desempenhado por um tipo específico de ficção literária na sua reelaboração da categoria de mímesis que, conforme o entendimento consagrado por sua tradução latina para imitatio, passou a ser tradicionalmente entendida como uma atividade passiva de busca por semelhança.
Diva e a histeria: o narrador médico e o controle da voz no romance de José de Alencar
Authors: Peres Marcos Flamínio
Published: May 2024

Resumo Diva (1864) talvez seja um dos romances mais mal-afamados de José de Alencar, tratado desde cedo como coisa menor: de “uma pieguice condenável” (Machado de Assis), marcado por “elefâncias do estilo” (Franklin Távora) ou, ainda, “obra que pouco ou nada vale” (Antonio Candido). No entanto, apresenta importante inovação para a literatura brasileira da época, que é a figura discursiva do narrador médico em primeira pessoa - o qual é sistematicamente rejeitado pela heroína em atitudes tidas como extremadas. Uma releitura feita à luz dos estudos pioneiros sobre a histeria, desenvolvidos por Charcot, Breuer e Freud e, posteriormente, por teóricas do feminismo (Elaine Showalter, Sandra Gilbert e Susan Gubar), pode ajudar a compreender tal recusa. A somatização de sintomas de ordem psíquica no corpo da mulher, que caracterizaria a primeira abordagem sobre a histeria, representa uma recusa sistemática da parte da heroína em aceitar o poder inédito de que foi investido a figura do médico ao longo do século 19, numa tentativa de preservar sua voz particular em meio a uma sociedade para a qual a mulher deve abdicar de sua autonomia e identidade. Junte a isso o plano narrativo, visto que o narrador médico em Diva detém não apenas o direito de invadir e clinicalizar o corpo de sua “paciente” como também de expô-la ao leitor sob seu exclusivo ponto de vista. Antecipando-se aos estudos sobre a histeria, o romance de folhetim de fato já representava a heroína, em Alexandre Dumas e Eugène Sue, como ameaça ao poder masculino enquanto personagem e narrador (Queffelec). Vinculando-se a essa singular tradição literária, Alencar faz de Diva um dos livros mais contundentes já escritos sobre a situação da mulher na sociedade brasileira da segunda metade do século XIX, culminando em um nível de tensão poucas vezes visto até então.
Parâmetros morfológicos e sintáticos na língua Bakairi (Karib): um enfoque da ergatividade
Authors: Souza Tania Conceição Clemente de
Published: May 2024

RESUMO Nossa análise com a língua Bakairi vem se sedimentando num corpus significativo resultante de sete pesquisas de campo, realizadas no período de 1984 a 1992, e quatro pesquisas mais recentes, realizadas entre 2019 a 2023. Todas as pesquisas tomam como foco a variedade de Bakairi falada na terra indígena Pakuenra. Dentro do enfoque da Teoria Gerativa, nosso trabalho busca investir na discussão em torno dos parâmetros de uma língua sintaticamente ergativa, perseguindo os seguintes objetivos (i) descrever o funcionamento dos verbos em Bakairi, a partir da distribuição dos paradigmas -aki e -tai, colocando em pauta a diátese verbal e a seleção de argumentos internos ao VP ou alocados em vP e (ii) reafirmar o status dos argumentos internos ao VP como argumentos canônicos versus o status derivados dos argumentos com papel de agente. Os principais resultados que temos alcançado vão ao encontro da definição de uma língua sintaticamente ergativa, uma vez que não estamos lidando com marcas nominais de caso, fato que vem contribuir para elucidar formalmente os tipos de alinhamento nas línguas naturais, âmbito onde se dão os debates sobre a noção de Caso (lexical/inerente e estrutural).
Onde os edifícios têm nome: enunciados aderentes no espaço urbano de São Paulo
Authors: Vitorino Catarina , Souza-e-Silva Maria Cecília Pérez de
Published: May 2024

RESUMO Este trabalho investiga a relação entre enunciação aderente e objetos arquitetônicos, discutindo os efeitos de sentido depreendidos pelos dispositivos discursivos de cenografia e ethos na arquitetura residencial paulistana. Com base nos princípios teóricos e metodológicos da análise do discurso e pesquisas na área da toponímia, é estruturada uma pesquisa de recorte geográfico com foco numa área central da cidade de São Paulo sujeita a diversas etapas de construção e em processo de transformação imobiliária crescente, com recorte temático-temporal definido pela afirmação da arquitetura moderna ao lançamento de novos imóveis na atualidade. Após considerações sobre os enunciados aderentes na paisagem urbana e a relação de aderência entre o enunciado e seu suporte, passa-se ao detalhamento do corpus delimitado para análise. Estabelecem-se, em seguida, os parâmetros de observação para o estudo dos enunciados aderentes, analisando-os e caracterizando-os de acordo com a área e a linguagem arquitetônica delimitada. Finalmente, as considerações sobre cenografia e relações interdiscursivas permitem concluir que os enunciados aderentes constituem um lugar privilegiado de observação da arquitetura, das transformações urbanas e dos discursos sobre tais transformações, na área central da cidade de São Paulo.
Educação linguística crítica para a transformação social radical: discussões sobre letramentos, criticidade e afeto em tempos de barbárie
Authors: Tilio Rogério , Rocha Claudia Hilsdorf
Published: May 2024

RESUMO Nossa proposta, neste artigo, é discutir a ideia de educação linguística crítica com vistas a uma transformação social radical, entendendo que esta só ocorre se conduzida de forma crítica e afetiva. Para isso, revisitamos o conceito de letramento crítico, buscando refletir sobre sua ligação com a afetividade. Após uma breve revisão do conceito de criticidade e de sua apropriação pedagógica pelas vertentes denominadas pensamento crítico, pedagogia crítica e letramento crítico, alinhamo-nos com uma perspectiva de criticidade como prática problematizadora a partir do engajamento com as diferenças. Argumentamos em favor de uma educação linguística pautada em uma postura crítico-afetiva, em tempos caóticos, a fim de que o processo educativo possa realizar-se de modo alinhado à filosofia freireana e, assim, revelar-se transformador e orientado para a paz. Por fim, apresentamos uma breve releitura da chamada pedagogia dos multiletramentos, com o intuito de fomentar possibilidades de encaminhamentos pedagógicos que contribuam, de fato, para a transformação social radical.
Clínica de Linguagem: sob efeito da novidade saussuriana
Authors: Lier-DeVitto Maria Francisca , Fonseca Suzana Carielo da , Arantes Lúcia
Published: May 2024

RESUMO Discute-se, neste artigo, o impacto do pensamento de Saussure no Interacionismo em Aquisição de Linguagem e, também, na Clínica de Linguagem. Trata-se de duas teorizações que emergem pela via de uma historicização crítica relativamente as esferas de que partem: uma, o Interacionismo, que se desenvolve e se estabelece em diálogo tenso com a área da Aquisição da Linguagem e, outra como campo da Fonoaudiologia. Parte-se do reconhecimento de que Saussure, embora admitido como “pai” da ciência da linguagem, raramente o impacto de seu pensamento se fez notar em seu berço de origem. Ele é, por outro lado, notável no campo amplo das ciências humanas em geral. Neste ambiente justifica-se destacar, neste trabalho, duas esferas em que efeitos de la langue (o objeto da Linguística) é mobilizado em suas estruturações e delimitações próprias. Este artigo realiza, ainda, o esforço de iluminar a diferença entre Interacionismo em Aquisição de Linguagem e Clínica de Linguagem, procurando mostrar que a referência a um mesmo fundo teórico não inibe a necessária exigência de distinção entre Aquisição e Patologias da Linguagem. Apesar dessa convergência teórica, parece crucial esclarecer a diferença entre os programas Interacionista e da Clínica da Linguagem. Tal distinção envolve o esforço de caracterizar o distanciamento empírico e conceitual existente entre os erros típicos, que ocorrem na fala infantil, e os erros sintomáticos que se cristalizam na fala de crianças ou adultos.
