PROTOCOLO DE BANDAGEM ELÁSTICA E DRENAGEM LINFÁTICA NO PÓS-OPERATÓRIO DE CESÁREA
Authors: Correia Alvarenga Claudia Cardinalle , Callegari Dhevilin , Da Silva Pumi Alliana Fernanda
Published: June 2024

Introdução: A drenagem linfática e a bandagem elástica são técnicas terapêuticas que oferecem benefícios distintos. A drenagem linfática estimula a circulação e reduz o inchaço, enquanto a bandagem elástica auxilia na estabilização e suporte muscular. Ambas as abordagens têm sido utilizadas com sucesso em contextos terapêuticos e estéticos. Objetivo: Assim, o objetivo deste estudo foi avaliar o processo álgico e sensorial em puérperas durante a cicatrização pós-operatória da cesárea, utilizando a combinação da bandagem elástica e/ou drenagem linfática. Métodos: Foram selecionadas duas pacientes, denominadas Paciente 1 e Paciente 2, que apresentaram queixas diferentes, sendo edema e queimação para a Paciente 1, e edema e sensibilidade para a Paciente 2. Os tratamentos aplicados foram distintos, com a Paciente 1 recebendo a combinação das duas técnicas (bandagem elástica e drenagem linfática), enquanto a Paciente 2 recebeu apenas a aplicação da drenagem linfática. Resultados: Verificou-se na Paciente 1 uma melhora na escala de dor de 7 para 0; enquanto para a Paciente 2 houve melhora de 7 para 1. Na avaliação de sensibilidade por estesiômetro, a Paciente 1 apresentou menor sensibilidade, mas com ocorrência de inflamação dos pontos. Porém, ao finalizar o tratamento a sensibilidade normal da área foi retomada. A Paciente 2 apresentou sensibilidade em todas as sessões. Conclusão: A técnica de drenagem linfática isolada ou associada com a aplicação de bandagens elásticas em X podem ser utilizadas de forma eficiente para a normalização do quadro de puérperas pós-cesárea. Recomenda-se que mais estudos na área sejam realizados com maior número amostral.

Published: June 2024

Objective. To describe, from a value management perspective, the impact of applying operational value drivers and microvalue drivers in a Private Higher Education Institution located in Medellín, Colombia. Methodology. This is qualitative research framed as a descriptive case study. It employs three stages to identify, determine, and propose value drivers for generating and managing value within the institution. Tools used for data collection included: (i) A reporting table to determine institutional microvalue drivers; (ii) financial statements from the last three years, and (iii) a report and recommendation for implementing value drivers within the organization. Results. The results showed it does not effectively build value despite the Private Higher Education Institution generating surpluses. Moreover, the institution’s performance analysis reveals that operational and non-operational expenses have grown at rates that overshadow revenue growth. Conclusions. The study concludes that while the institution is profitable, it struggles with value creation due to onerous asset costs relative to net surpluses. The findings indicate potential medium to long-term liquidity issues due to inefficient working capital management and increased delinquency rates, suggesting that profitability and liquidity drivers are not optimally managed.

Además se determinó que el área seleccionada para publicación es economía y los journal que mayormente publican el tópico de brecha salarial son Labour Economics e International Journal of Manpower.
Metrical enhancement in American English nuclear tunes
Authors: Steffman Jeremy , Cole Jennifer
Published: June 2024

We present two experiments aimed at testing the nature of intonational categories through the lens of enhancement. In an imitative speech production paradigm, speakers heard a model intonational tune and were prompted to reproduce that tune on a new sentence in which the syllable count of the word carrying the tune varied. Using the prevalent auto-segmental metrical model of American English as a basis for potential tune categories, we test how distinctions among tunes are enhanced across different metrical structures. First, with a clustering analysis, we find that not all predicted distinctions are emergent. Secondly, only the largest distinctions, those that emerge in the clustering analysis, are enhanced as a function of metrical structure. Measurable differences between tunes which cluster together are detectable, but critically, are not enhanced. We discuss what these results mean for the nature and number of intonational categories in the system.
THE NETWORK MODEL OF REGIONS' PARTICIPATION IN INTERNATIONAL AUTOMOBILE PRODUCTION: CASE OF EU COUNTRIES
Authors:   Institute of Europe RAS, VASILCHENKO A.D.
Published: June 2024

The paper assesses the current participation of EU countries' regions in international production. The study aims to test the hypothesis that an increasing participation of the Visegrad countries in the EU automobile production network has been accompanied by a lowering disproportionality of value added produced in these regions and the largest EU countries. To this end, quantitative indicators of spatial differences and centrality of countries in production networks were calculated. The article revealed that value added disparities between the Visegrad countries and the core countries of the EU automobile production decreased notably along with a reduced variation of centrality scores. The findings clarified that the participation of regional firms in international production positively affects the region's economy. The research results are relevant in the context of setting priorities for national and regional industrial policies. The following studies might examine the role of international production networks in industrial diversification of a regional economy.

Authors: Figueroa-Céspedes Ignacio , Fica-Pinol Esteban
Published: June 2024

Antecedentes: los incidentes críticos que enfrentan las educadoras de párvulos aún no han sido objeto de una investigación exhaustiva. Estudiarlos en profundidad puede ayudar a identificar áreas de mejora, fortaleciendo así su formación e identidad profesional, y elevando la calidad de la educación infantil. Objetivo: describir y caracterizar situacional y emocionalmente los Incidentes Críticos (IC) reportados por un conjunto de 120 educadoras de párvulos de diferentes regiones de Chile, entre 2018 y 2019. Metodología: se trata de un estudio cualitativo, de alcance descriptivo-interpretativo con orientación narrativa, desarrollado a partir de pautas de registro de IC en las que cada educadora reporta experiencias límite que han perturbado su accionar. Se obtiene un total de 173 IC. Se lleva a cabo un análisis temático narrativo en el que se agrupan los IC y se caracterizan por tipo de situación y emociones. Resultados: se identifican tres tipos de situaciones: incidentes de convivencia (n=102), incidentes pedagógicos (n=53) e incidentes en el abordaje de la diversidad (n=18). Las experiencias relatadas se caracterizan desde las emociones negativas, predominando la Ansiedad y Tristeza, y en menor medida, Ira y Sorpresa. Conclusiones: la variedad de situaciones identificadas, que abarcan desde conflictos de convivencia hasta desafíos para abordar la diversidad, subrayan la complejidad del trabajo docente en educación infantil. En este contexto, la definición de los incidentes críticos se entrelaza con su componente emocional, lo que resalta la importancia de articular el cuidado y la pedagogía desde un enfoque colaborativo.

Authors: Motta Totena Erika Paola , Valencia González Gloria Clemencia , Torres Sabaté María Concepción
Published: June 2024

Objetivo: reflexionar acerca de los despliegues metodológicos implicados en una investigación sobre el análisis bidimensional de los pensamientos sociales emergentes en un contexto educativo inclusivo con la comunidad sorda y oyente en el municipio de Ibagué, Tolima en Colombia. Metodología: la investigación se apoyó en el movimiento simbólico de un circuito sistémico desde la propuesta PEMM [Paradigma, Enfoque, Método, Momentos] con cuatro engranajes ontoepistémicos; el primero de ellos suscrito dentro del constructivismo; el segundo, guiado por la mirada cualitativa; el tercero, materializado en la teoría fundamentada; y finalmente seis acciones prácticas y estructurantes de refinación teórica, cimentadas en la aplicación de los métodos asociativos e interrogativos a través de cuatro técnicas: 1. Observación participante, 2. Entrevistas semiestructuradas, 3. Revisión documental y 4. Cartas relacionales. Resultados: los principales hallazgos se consolidaron en un sistema de circulación social entre las construcciones de orden informativo y las transformaciones de carácter representativo, en donde se exteriorizan los trazos sociales de la inclusión, las acciones formativas y el reconocimiento entre los sujetos que comparten sus aprendizajes en una misma institución, aula y sociedad. Conclusiones: el tránsito entre los pensamientos informativos y representativos permitió comprender que los pensamientos sociales, en su conjunto, están cargados y dinamizados por disímiles imágenes, explicaciones, significados y sentidos, que se vinculan las formas de relación humana, en este caso entre oyentes y sordos, desafiando las ideas estereotipantes y hegemónicas que encasillan la identidad Sorda y la LSC como una carencia, enfermedad o discapacidad que requiere ser rehabilitada.

The Impact of Empathy and Fear on Solidarity during a Pandemic
Authors:   The City University of New York (СUNY), New York, USA, Marchenko Fedor , Makhovskaya Olga ,   Institute of Psychology, Russian Academy of Sciences, Moscow, Russian Federation
Published: June 2024

It is believed that solidarity is motivated by positive collective feelings (group cohesion, social responsibility, etc.), as well as by individual empathy of group members. Motivation may change vector if all members of society are potential victims of a pandemic. An analysis of data obtained from an online survey of 331 Russian-speaking respondents (19 countries) from March 2021 to April 2023 revealed a weak link between empathy (both affective and cognitive) and the solidarity attitudes on safe behavior. On the contrary, a significant correlation was found between negative Ego-feelings (fear for oneself and health) and the expression of the most important solidarity attitudes -wearing masks, social distancing and vaccination. This contradicts the old tradition of considering individual empathy as the principal factor of collective solidarity. In particular, the bodily metaphor of rapprochement, embracing with others, which is the core of empathy, contradicts the requirement of physical distance. A positive correlation was also noted between the pronouncement of solidarity attitudes and the experience of material aid to strangers. Fears for oneself and empathy for others are experiences with opposite vectors. Fears can block empathy. Thus, the phenomenon of synchronous behavior of people, similar to solidarity, but with nonspecific negative motivation, was discovered. We believe that solidarity-like activity should be distinguished from conscious, trained solidarity based on the belief that suffering and unprotected groups and people need to be supported by the state and other citizens.
An Experimental Analysis of Moral Conformity in a Situation of Passive Social Pressure
Authors:   Novosibirsk State University, Novosibirsk, Russian Federation, Fedorov Alexandr
Published: June 2024

This article presents the results of three experiments aimed at studying moral conformity under conditions of passive virtual pressure in the Russian cultural context. Moral conformity is defined as a social pressure-induced change in public moral behavior. The experiments used moral dilemmas as stimulus material, and moral behavior was assessed through the frequency of specific answers to these dilemmas. Social pressure was exerted by informing participants, who were filling out an online form, about the percentage of people responding to moral dilemmas in a certain way. This type of influence is considered as a passive virtual form of social pressure without an explicit identifiable source. The results of the first two experiments showed that passive virtual pressure leads to a change in the frequency of consequentialist responses, indicating the emergence of moral conformity. However, no differences between genders were found in the patterns of moral conformity. In contrast to foreign studies, an effect of asymmetric conformity in favor of the consequentialist majority, rather than the deontological majority, was observed. The third experiment, which differed in design and set of moral dilemmas from the two previous studies, showed that both consequentialist and deontological passive virtual social pressure induce moral conformity for all three types of dilemmas (personal, impersonal, and third-person dilemmas). It was found that women respond significantly less to consequentialist pressure in the case of third-person formulated dilemmas. Thus, conforming moral response may depend on the specific design of the study, the type and content of moral dilemmas, as well as the individual characteristics of the participants.
Realizing the Potentials of Reflection in the Construction Reflective Practices
Authors:   HSE University, Moscow, Russian Federation, Starovoytenko Elena
Published: June 2024

In the early 1990s, the author published a book where she theoretically, phenomenologically and empirically substantiated the role of reflection in the formation of professional, creative, and ethical attitudes of a scientist. The book developed a methodology for converting the conceptual model of attitudes and their reflexive mediation into various practices of reflection oriented to the adult developing personality. This article highlights the results of the author’s new research focused on the problem of developing theoretically grounded reflective practices in the field of general personology. The methods of hermeneutics and conceptual modelling were used to identify the potentials of reflection in individual life: cultural, psychological, existential, and practical. We emphasized the practical potential of reflection, which, in unity with other potentials, determines the development of specific reflective practices, including their intentional, significative, operational, semantic aspects. The forms of reflection that set the content and structure of various reflexive practices have been identified. These forms include self-exploration, self-evaluation and recognition of self-value, self-reflection, self-expression, inner dialogue with a significant Other, reflection on a life path. Based on references to culture, psychology, and the experience of individual self-knowledge, as well as on the outlined classification of forms of reflection and the model of step-by-step construction of reflective practices, the author, following the main goal of the research, proposes a number of reflective practices. These include the practice of reflective disclosure of one’s life problems; the practice of reflective dialogue of the Self with another as “You”; the practice of dialogical achievement of self-identity of the Self; the practice of reflection of key life experiences; the practice of reflective discovery of the unknown Self. The developed practices are oriented to application in personality research, in the context of counselling and psychotherapeutic work and in individual self-knowledge.
The Development and Initial Validation of the Self-Regulated Learning Strategies Survey for Elementary School Students
Authors:   HSE University, Moscow, Russian Federation, Akhmedjanova Diana , Lizunova Evgenia ,   HSE University, Moscow, Russian Federation
Published: June 2024

Self-regulated learning (SRL) refers to the processes of setting goals, monitoring progress, selecting learning strategies, and revising learning goals. Research evidence shows positive associations between SRL and academic achievement, motivation, well-being, and other constructs. The purpose of this paper is to establish the initial evidence of the construct validity of the SRL Strategies survey for elementary school students. The SRL Strategies survey includes 12 items, focusing on the strategies of environment, time, and learning management ranging from 1 (almost never) to 4 (almost always) on a Likert-type scale. The unified validity framework (Messick, 1995) was used to conduct the validation study by collecting content, internal structure, convergent, discriminant, and response processes evidence. The application of classical test theory (CTT) using exploratory and confirmatory factor analyses, reliability estimates, and Pearson’s correlations on a sample of 1,877 fourth graders provided initial evidence of construct validity by suggesting a one-factor model, which was confirmed on another sample of elementary school students (n = 317). The additional item response theory (IRT) analyses provided evidence of differential item functioning for Items 2, 5, and 6 based on student gender, but not on location. Combined evidence from CTT and IRT analyses resulted in acceptable properties of the combined one-factor SRL Strategies survey (α = 0.83; ωh = 0.71, ωt = 0.85). As a result, the SRL Strategies survey can be recommended for the use by researchers and practitioners.
Insight Problem or Insightful Solution: Is It Still Worth Using Insight Problems to Investigate Insight?

Traditional insight studies assumed that there is a special class of problems called “insight problems” whose solution would cause feelings of insight. However, it has been previous shown that insight problems can be solved in both insightful (with Aha! experience) and step-by-step (without Aha! experience) ways, and exactly the same is observed for analytical problems. The present work addresses the question whether it is sufficient to use the problem types to detect insightful feelings or whether it is necessary to use the solution types. For this purpose we collected the dataset of previously published open data which used Danek and Wiley’s questionnaire for subjective ratings of insight phenomenology. Joint analysis showed that using solution types provided greater benefits for insight investigation than using problem types: insightful solutions were more pleasant, sudden, and relieving than step-by-step solutions, but insight and analytical problems differed from each other on only suddenness scale. We concluded that relying only on the problem type is not the best strategy for investigation of insight, because insight and analytical problems are quite similar in terms of the Aha! experience. The use of solution types is much more fruitful and distinguishes various situations in the process of problem solving. The obtain results were interpretated in the context of relationships between the Aha! experience and representational change.

Objectives: To define the term ‘semimediality’ in the near ring and to demonstrate its presence with an example and to employ several attributes in near rings to analyse its features. Methods: Semimedial near rings are examined in terms of their characteristics using commutativity, distributivity and regular property. The distinction is observed using the concept of homomorphism. Findings: Every near ring which is weak commutative is proved to be semimedial and the converse exists with some additional axioms. The semimedial near ring’s anti-homomorphic image is also observed. Additionally, the correlation between the semimedial near ring and the reduced property is identified. Novelty: This study provides a novel method to medial near ring, which is the semimedial near ring. Keywords: Identity, Left Self Distributive, Nilpotent, Regular, Weak Commutative

Published: June 2024

Objectives: The research work focuses on providing an effective framework for automated text refinement that aids in financial condition projections for the company based on prior transcripts of earnings calls. The proposed framework captures the ad hoc advancements of the organizations described in the earnings call as sentiments and computes a score based on the captured sentiments. The sentiment score is then used as prime parameter to predict the stock values of the organizations. Methods: The framework is equipped with sentiment analysis or opinion mining to identify and extract the subjective content using text mining and Natural Language Processing (NLP). The extracted sentiments help in yielding a sentiment score to aid in the process of stock projection. The research also illustrates how the sentiment score-based stock prediction enhances in projections of stock compared to existing ML frameworks like LSTM, Random Forest, ARIMA and Regression models. Findings: The proposed work has an accuracy score of 93%, precision 96% and recall 95% which is comparatively better than existing ML frameworks framed on LSTM, Random Forest, ARIMA and Regression models. Novelty: The research framework overcomes the influence of regular features and test data in stock prediction by using the computed sentiment prediction score from the extracted sentiment phase to aid in prediction stock values and determine the financial status of organizations. The existing frameworks project the stock price based on trained model from previous stock price repository, which tend to fail capturing ad hoc changes incurring in the organization such as change of management or any economic disaster which can poses a high impact on stock projections, the proposed research work captures these organizational changes from the earnings call transcripts as sentiments and build a score to yield the stock projection framework.

Policy Transfer for Sexual Violence Prevention and Management in Indonesian Higher Education Institutions
Authors: Nengyanti Nengyanti , Yusnaini Yusnaini , Imania Katriza , Santoso Anang Dwi
Published: June 2024

This research delves into the intricacies of policy transfer in the domain of sexual violence prevention and management within Indonesian Higher Education Institutions (HEIs). Through a phenomenological approach, the study engaged with 15 key informants and scrutinized 17 policy documents, uncovering that the applicability of such policies is not universal and is significantly influenced by diverse social, economic, and political contexts. The study underscores the important role of effective communication with the Ministry of Education, Culture, Research, and Technology, advocating for an understanding of the varied contexts in which these policies are executed. It highlights the disconnection between policy formulation and its practical enactment, suggesting that initial attempts at linear policy transfer eventually evolve into more complex processes once implementation unfolds. This complexity arises from the intersection of theoretical policy frameworks with the pragmatic realities of institutional contexts, underlining the need for adaptable and context-sensitive approaches in the fight against sexual violence in educational settings.

Sustainability should become a key concern in the next generation of engineered systems. While this expectation is relatively straightforward, the question of how to get there is less obvious. The multi-dimensional and intricate nature of sustainability poses challenges in designing sustainable systems and analyzing sustainability properties. Finding trade-offs between economic, environmental, societal, and technological aspects of sustainability is a wicked problem and calls for advanced modeling and simulation methods. In this paper, we report on a panel discussion held at the 28th Working Conference on Exploring Modeling Methods for Systems Analysis and Development (EMMSAD) with four esteemed experts representing four complementary and often conflicting perspectives on the role of modeling for sustainability – stakeholders, digitalization, degrowth and IT, and ethics. We report the key arguments of the panelists, discuss the roles of modeling in the analysis and design of sustainable systems, and, finally, elaborate on the conflicts among the perspectives, their effects, and potential resolutions.

Information systems (IS) conferences, as venues for the introduction of new knowledge to the IS community, require effective peer review systems to evaluate submitted research for quality, validity, and originality. We argue in this paper that questionable practices and degrading review quality may arise without direct incentives beyond reviewer altruism to engage in the peer review process. In particular, we highlight potential issues with arguably common practices in some IS conferences, such as peer review invitations sent to researchers who have also submitted papers for publication consideration and the increasing number of reviews performed by graduate students. To address these issues, we suggest three solutions: 1) quid pro quo rules; 2) the use of incentive-compatible methods whose scores are linked to relevant rewards; and 3) the use of blockchain-based tokens in tandem with smart contracts and zero-knowledge proofs. We conclude by offering directions the IS community can take to further study the highlighted issues and implement the proposed solutions.

START Foundation annually supports nearly 200 young people with a migratory background through an individualized scholarship program aimed at personal development and identity building. In 2022, START Foundation expanded its reach by launching a digital learning platform, which faced challenges such as information overload and navigation difficulties due to a growing number of courses and a lack of individual support. To improve user experience on the digital learning platform, START Foundation explored implementing a recommender system for personalized course navigation based on methods from the field of artificial intelligence (AI). However, this exploration raised ethical concerns, particularly regarding bias and fairness in AI systems. In light of these concerns, the following questions emerged: Should START Foundation integrate the AI-based recommender system into its digital learning platform? If so, what factors should START Foundation consider regarding bias and fairness in its AI-based recommender system in order to prevent negative consequences for its scholars? Readers are encouraged to explore the interactive learning module on bias and fairness in AI systems, available at https://bias-and-fairness-in-ai-systems.de/en/home/.

Bu çalışmada soya fasulyesi yağı esaslı, UV ışınları ile kürlenebilen bir oligomer sentezlenmiş ve bu oligomer liken partikülleri ile takviye edilerek kaplama formülasyonları hazırlanmıştır. Geliştirilen kaplama formülasyonları pamuk kumaşlar üzerine çevre dostu bir kaplama malzemesi olarak uygulanmış ve çevre dostu bir yöntemle (UV ışınları ile) kürlenmiştir. Liken partikülleri, kaplama malzemesi ile pamuk kumaş arasında bağlanma mekanizmasını geliştirmek ve sonucunda mekanik özellikleri iyileştirmek amacı ile kullanılmıştır. Liken ve oligomer arasındaki uyumu arttırmak için liken partiküllerinin yüzeyi çevre dostu iki yöntem ile (enzimatik ve UV ışınları) modifiye edilmiştir. Sentezlenen biyo-esaslı oligomer Fourier dönüşümlü kızılötesi (FTIR) ve proton nükleer manyetik rezonans (1H NMR) spektroskopileri, modifiye edilen liken partikülleri ise X-ışını kırınım difraktometresi (XRD) ile karakterize edilmiştir. Biyo-esaslı kaplama formülasyonları ile kaplanan pamuk kumaşlar ışık mikroskobu ile incelenmiş, mekanik özelliklerini tespit etmek amacı ile mukavemet ve sürtünme dayanımı testleri gerçekleştirilmiştir. Tüm bulgular değerlendirildiğinde biyo-esaslı kaplama malzemesi ile kaplanan pamuk kumaşların, geleneksel petrokimyasal kaplı dış mekân tekstillerine (tente, branda vb.) çevre dostu malzeme ve yöntemle üretilen bir alternatif olarak kullanılabileceği sonucuna ulaşılmıştır.

In automotive audio playback systems, dynamically increasing driving sounds are typically taken into account by applying a generic, i.e., non-individualized, increase in overall level and low-frequency amplification to compensate increased masking. This study investigated the degree of individuality regarding the preferences of noise-dependent level and equalizer settings. A user study with 18 normal-hearing participants was conducted in which individually preferred level-dependent and frequency-dependent amplification parameters were determined using a music-based procedure in quiet and in nine different driving noise conditions. The comparison of self-adjusted parameters suggested that, on average, participants adjusted higher overall levels and more low-frequency amplification in noise than in quiet. However, preferred self-adjusted levels differedmarkedly between participants for the same listening conditions but were quite similar in a re-test session for each participant, indicating that individual preferences were stable and could be reproducibly measured with the employed personalization scheme. Furthermore, the impact of driving noise on individually preferred settings revealed strong interindividual differences, indicating that listeners can differ widely with respect to their individual optimum of how equalizer and level settings should be dynamically adapted to changes in driving conditions.
Analysis and Model of Temporal Sound Attributes from Recorded Audio
Authors: Moiragias George , Mourjopoulos John
Published: June 2024

A computational framework is proposed for analyzing the temporal evolution of perceptual attributes of sound stimuli. As a paradigm, the perceptual attribute of envelopment, which is manifested in different audio sound reproduction formats, is employed. For this, listener temporal ratings of the envelopment for mono, stereo, and 5.0-channel surround music samples, serve as the ground truth for establishing a computational model that can accurately trace temporal changes from such recordings. Combining established and heuristic methodologies, different features of the audio signals were extracted at each segment that envelopment ratings were registered, named long-term (LT) features. A memory LT computational stage is proposed to account for the temporal variations of the features through the duration of the signal, based on the exponentially weighted moving average of the respective LT features. These are utilized in a gradient tree boosting, machine learning algorithm, leading to a Dynamic Model that accurately predicts the listener’s temporal envelopment ratings. Without the proposed memory LT feature function, a Static Model is also derived, which is shown to have lower performance for predicting such temporal envelopment variations.
The Use of Interactive Metadiscourse in Research Articles: A Corpus-Based Case Study of Astronautics
Authors: Sun Yue
Published: June 2024

Based on Hyland’s interpersonal model of interactive metadiscourse, this study adopts astronautics as a research case to investigate the textual features of research articles, aiming to investigate the use of metadiscourse in research articles and assist academic writing for students who major in astronautics. A corpus consisting of 43 research articles published in Journal of Guidance, Control and Dynamics (JGCD) in 2020 and 2021 was built. AntConc 3.5.9 was utilized for searching and counting the standardized frequency results, so as to identify the most frequently used expressions. Results show that transition markers are most frequently used (35.72 per 1,000-word tokens), accounting for 65.62% of the total amount of interactive metadiscourse. The frequency of evidentials is the lowest, i.e., 0.26 per 1,000-word tokens, accounting for 0.48%. These indicate that transition markers play an important role in research articles in astronautics owing to the high requirement of logical expression. The low frequency of evidentials reflects low-level of dependency from others’ opinions, focusing on own experiments and argumentations. The relatively high frequencies of frame markers and endophoric markers confirm that straightforward logic and clear structure together with transparent figures are preferred in research articles in astronautics.
