Published: August 2024

As societal concern for environmental and public health issues intensifies, precisely monitoring harmful heavy metal concentrations in aquatic systems has become a critical scientific endeavor. Although laser-induced breakdown spectroscopy (LIBS) allows for the simultaneous detection of multiple elements, its sensitivity for tracing metal in water remains inadequate. This work investigates the enhancement of LIBS signals for chromium (Cr) and lead (Pb) detection of micro/nanostructures on aluminum surfaces, generated by femtosecond laser irradiation. These structures effectively reduce the coffee-ring effect, increasing plasma temperature and electron density. At a concentration of 100 µg/L, the spectral intensities of Cr and Pb increased by 378% and 307%, respectively. Consequently, this reduced the detection limits to 6.33 µg/L for Cr and 2.53 µg/L for Pb. Additionally, a partial least squares regression (PLSR) model was employed to quantitatively analyze the concentrations of Cr and Pb in water, achieving correlation coefficients (R2) of 0.997, 0.981 for Cr, and 0.995, 0.977 for Pb, in the training and prediction sets, respectively. This work demonstrates that integrating micro/nanostructures induced by femtosecond lasers on aluminum surfaces with the PLSR model substantially improves the detection sensitivity for trace amounts of Cr and Pb in water, offering new avenues for environmental monitoring and research.

Published: August 2024

Vector orbital angular momentum (OAM) beams, described by higher-order Poincaré (HOP) sphere, are generalized forms of waves carrying OAM with an inhomogeneous polarization of wavefronts. We construct all-dielectric metasurfaces with adjustable amplitude, polarization, and phase to generate arbitrary vector OAM beams. The metasurface is composed of two pairs of silicon nanopillars arranged alternately. Using the interference effect of the four meta-atoms related to the circular polarization, combined with the propagation and geometric phases, two OAM beams with controlled amplitude, phase, and equal topological charge but opposite signs can be obtained under the incidence of orthogonally circularly polarized lights. For the x linearly polarized light, arbitrary vector OAM beams on the HOP sphere are generated via the superposition of the above OAM beams. Additionally, the evolution process of the beam on the longitude and latitude of the Poincaré sphere is revealed by changing the amplitude and phase of the two OAM beams. This work provides a simple, effective, and flexible method for realizing vector OAM beams while having potential implications for the generation and manipulation of vectorial light fields at the micro-nano scale.

Published: August 2024

Postoperative delirium (POD) contributes to severe outcomes such as death or development of dementia. Thus, it is desirable to identify vulnerable patients in advance during the perioperative phase. Previous studies mainly investigated risk factors for delirium during hospitalization and further used a linear logistic regression (LR) approach with time-invariant data. Studies have not investigated patients’ fluctuating conditions to support POD precautions. In this single-center study, we aimed to predict POD in a recovery room setting with a non-linear machine learning (ML) technique using pre-, intra-, and postoperative data. The target variable POD was defined with the Nursing Screening Delirium Scale (Nu-DESC) ≥ 1. Feature selection was conducted based on robust univariate test statistics and L1 regularization. Non-linear multi-layer perceptron (MLP) as well as tree-based models were trained and evaluated—with the receiver operating characteristics curve (AUROC), the area under precision recall curve (AUPRC), and additional metrics—against LR and published models on bootstrapped testing data. The prevalence of POD was 8.2% in a sample of 73,181 surgeries performed between 2017 and 2020. Significant univariate impact factors were the preoperative ASA status (American Society of Anesthesiologists physical status classification system), the intraoperative amount of given remifentanil, and the postoperative Aldrete score. The best model used pre-, intra-, and postoperative data. The non-linear boosted trees model achieved a mean AUROC of 0.854 and a mean AUPRC of 0.418 outperforming linear LR, well as best applied and retrained baseline models. Overall, non-linear machine learning models using data from multiple perioperative time phases were superior to traditional ones in predicting POD in the recovery room. Class imbalance was seen as a main impediment for model application in clinical practice.

Authors: Taniguchi Yu , Ikeuchi Tomoko , Yong Jongsay
Published: August 2024

This study used the nationally representative prospective study of the Household, Income and Labour Dynamics in Australia (HILDA) survey cohort to examine the association of pet ownership (dog, cat, bird, fish, and others) with the risk of all-cause mortality using propensity score matching based on a wide range of factors. The study sample included 15,735 participants who completed the questionnaire on pet ownership in 2018. The HILDA survey sample was matched to the National Death Index through 2022 to assess death during the follow-up period. Statistical analysis was weighted by the inverse of the propensity score in the generalized estimating equation. During the 4-year follow-up period, 377 of 15,735 (2.4%) participants died. The odds ratios (ORs) for all-cause mortality were 0.77 (95%CI: 0.59–0.99) for dog owners compared to non-pet owners after controlling for related socio-demographic, physical, psychological, and social factors. The Sobel test showed a partial mediating effect of physical activity level on the relationship between dog ownership and all-cause mortality. Ownership of cats, birds, fish, and others showed no clear association with mortality, despite owners having similar socio-demographics characteristics to dog owners. Companionship and exercise of a pet dog may be recommended as a component of health promotion policy, and may have an important role to play in promoting health aging.

Multidrug resistance (MDR) mechanisms in cancer cells are greatly influenced by glutathione transferase P1-1 (hGSTP1-1). The use of synthetic or natural compounds as hGSTP1-1 inhibitors is considered an effective approach to overcome MDR. Nine compounds consisting of coumarin-6-sulfonamide linked to chalcone derivatives were synthesized and evaluated for their ability to inhibit hGSTP1-1. Among the synthetic derivatives, compounds 5g, 5f, and 5a displayed the most potent inhibitory effect, with IC50 values of 12.2 ± 0.5 μΜ, 12.7 ± 0.7 and 16.3 ± 0.6, respectively. Kinetic inhibition analysis of the most potent molecule, 5g, showed that it behaves as a mixed-type inhibitor of the target enzyme. An in vitro cytotoxicity assessment of 5a, 5f, and 5g against the human prostate cancer cell lines DU-145 and PC3, as well as the breast cancer cell line MCF-7, demonstrated that compound 5g exhibited the most pronounced cytotoxic effect on all tested cell lines. Molecular docking studies were performed to predict the structural and molecular determinants of 5g, 5f, and 5a binding to hGSTP1-1. In agreement with the experimental data, the results revealed that 5g exhibited the lowest docking score among the three studied inhibitors as a consequence of shape complementarity, governed by van der Waals, hydrogen bonds and a π-π stacking interaction. These findings suggest that coumarin-chalcone hybrids offer new perspectives for the development of safe and efficient natural product-based sensitizers that can target hGSTP1-1 for anticancer purposes.

Published: August 2024

Tart cherries have low glycemic index, antioxidant and anti-inflammatory properties, and therefore may benefit performance and recovery from exercise. We determined the effects of consuming tart cherry juice versus a high-glycemic index sports drink on cycling performance, substrate oxidation, and recovery of low-frequency fatigue. Using a randomized, counter-balanced cross-over design, with one-month washout, 12 recreational cyclists (8 males and 4 females; 35±16y; VO2peak 38.2±7.4 ml/kg/min) consumed cherry juice or sports drink twice a day (300mL/d) for 4d before and 2d after exercise. On the exercise day, beverages (providing 1g/kg carbohydrate) were consumed 45min before 90min of cycling at 65%VO2peak, followed by a 10km time trial. Blood glucose, lactate, carbohydrate and fat oxidation, respiratory exchange ratio (RER), O2 cost of cycling, and rating of perceived exertion (RPE) were measured during the initial 90min of cycling. Muscle soreness, maximal voluntary contraction (MVC) and low-frequency fatigue were determined at baseline and after the time trial on the exercise day, and 30min after beverage consumption 24 and 48h later. There were no differences for time trial performance (17±3min cherry juice vs. 17±2min sports drink, p = 0.27) or any other measures between drink conditions. There were time main effects (p<0.05) for isometric MVC (decreasing) and low-frequency fatigue (increasing; i.e. decreased force at low relative to high stimulation frequencies), changing significantly from baseline to post-exercise and then returning to baseline at 24h post-exercise. Tart cherry juice was not effective for improving performance, substrate oxidation during exercise, and recovery from exercise, compared to a high-glycemic index sports drink.
Modeling human activity-related spread of the spotted lanternfly (Lycorma delicatula) in the US

Published: August 2024

The spotted lanternfly (Lycorma delicatula) has recently spread from its native range to several other countries and forecasts predict that it may become a global invasive pest. In particular, since its confirmed presence in the United States in 2014 it has established itself as a major invasive pest in the Mid-Atlantic region where it is damaging both naturally occurring and commercially important farmed plants. Quarantine zones have been introduced to contain the infestation, but the spread to new areas continues. At present the pathways and drivers of spread are not well-understood. In particular, several human activity related factors have been proposed to contribute to the spread; however, which features of the current spread can be attributed to these factors remains unclear. Here we collect county level data on infestation status and four specific human activity related factors and use statistical methods to determine whether there is evidence for an association between the factors and infestation. Then we construct a network model based on the factors found to be associated with infestation and use it to simulate local spread. We find that the model reproduces key features of the spread 2014 to 2021. In particular, the growth of the main infestation region and the opening of spread corridors in the westward and southwestern directions is consistent with data and the model accurately forecasts the correct infestation status at the county level in 2021 with 81% accuracy. We then use the model to forecast the spread up to 2025 in a larger region. Given that this model is based on a few human activity related factors that can be targeted, it may prove useful to incorporate it into more elaborate predictive forecasting models and in informing management efforts focused on interstate highway transport and garden centers in the US and potentially for current and future invasions elsewhere globally.
Muscle short-range stiffness behaves like a maxwell element, not a spring: Implications for joint stability
Authors: Barrett Jeff M. , Malakoutian Masoud , Fels Sidney , Brown Stephen H. M. , Oxland Thomas R.
Published: August 2024

Introduction

Muscles play a critical role in supporting joints during activities of daily living, owing, in part, to the phenomenon of short-range stiffness. Briefly, when an active muscle is lengthened, bound cross-bridges are stretched, yielding forces greater than what is predicted from the force length relationship. For this reason, short-range stiffness has been proposed as an attractive mechanism for providing joint stability. However, there has yet to be a forward dynamic simulation employing a cross-bridge model, that demonstrates this stabilizing role. Therefore, the purpose of this investigation was to test whether Huxley-type muscle elements, which exhibit short-range stiffness, can stabilize a joint while at constant activation.

Methods

We analyzed the stability of an inverted pendulum (moment of inertia: 2.7 kg m2) supported by Huxley-type muscle models that reproduce the short-range stiffness phenomenon. We calculated the muscle forces that would provide sufficient short-range stiffness to stabilize the system based in minimizing the potential energy. Simulations consisted of a 50 ms long, 5 Nm square-wave perturbation, with numerical simulations carried out in ArtiSynth.

Results

Despite the initial analysis predicting shared activity of antagonist and agonist muscles to maintain stable equilibrium, the inverted pendulum model was not stable, and did not maintain an upright posture even with fully activated muscles.

Discussion & conclusion

Our simulations suggested that short-range stiffness cannot be solely responsible for joint stability, even for modest perturbations. We argue that short-range stiffness cannot achieve stability because its dynamics do not behave like a typical spring. Instead, an alternative conceptual model for short-range stiffness is that of a Maxwell element (spring and damper in series), which can be obtained as a first-order approximation to the Huxley model. We postulate that the damping that results from short-range stiffness slows down the mechanical response and allows the central nervous system time to react and stabilize the joint. We speculate that other mechanisms, like reflexes or residual force enhancement/depression, may also play a role in joint stability. Joint stability is due to a combination of factors, and further research is needed to fully understand this complex system.
Effects of gender sensitive language in job listings: A study on real-life user interaction
Authors: Hetjens Dominik , Hartmann Stefan
Published: August 2024

The possible impact of gender-sensitive language on readers is among the most controversially debated issues in linguistics and beyond. Previous studies have suggested that there is an effect of gender-sensitive language on mental representations, based on data gathered in laboratory settings with small groups of participants. We add a new perspective by examining correlations of authentic language use with authentic user interaction on a recruitment website. Drawing upon a large dataset provided by the recruitment platform StepStone, we evaluate whether job advertisements using certain kinds of gender-sensitive language in their titles correlate with higher proportions of views by female users. Our results indicate that there are differing effects depending on the type of gender-sensitive language that is used. Overall, the strongest correlation can be found with terms that include the feminine suffix -in.

Published: August 2024

Breast cancer remains a significant contributor to cancer-related deaths among women globally. We seek for this study to examine the correlation between the incidence rates of breast cancer and newly identified risk factors. Additionally, we aim to utilize machine learning models to predict breast cancer incidence at a country level. Following an extensive review of the available literature, we have identified a range of recently studied risk factors associated with breast cancer. Subsequently, we gathered data on these factors and breast cancer incidence rates from numerous online sources encompassing 151 countries. To evaluate the relationship between these factors and breast cancer incidence, we assessed the normality of the data and conducted Spearman’s correlation test. Furthermore, we refined six regression models to forecast future breast cancer incidence rates. Our findings indicate that the incidence of breast cancer is most positively correlated with the average age of women in a country, as well as factors such as meat consumption, CO2 emissions, depression, sugar consumption, tobacco use, milk intake, mobile cells, alcohol consumption, pesticides, and oral contraceptive use. As for prediction, the CatBoost Regressor successfully predicted future breast cancer incidence with an R squared value of 0.84 ± 0.03. An increased incidence of breast cancer is mainly associated with dietary habits and lifestyle. Our findings and recommendations can serve as a baseline for developing educational programs intended to heighten awareness amongst women in countries with heightened risk.

This article constitutes the second part of a series of papers devoted to 1117 Polish derivational neologisms in Obserwatorium Językowe Uniwersytetu Warszawskiego (Language Obserwatory of the University of Warsaw). Its aim is to present and analyse 334 new substantival compounds in the Polish language. The author divides them into groups of derivational neologisms created by the use of the same formative technique and containing the same part of the compound. The study concludes that the biggest class of the described new substantival compounds in contemporary Polish language consists of structures without any affixes. As for the morphemes used to create them, the interfix -o- turned out to be the most productive. Most of them contain the elements e- (abbreviated adjective elektroniczny [electronic]) and -mat (abbreviated noun automat).
Discourses Related to the Activities of Local Offices in the 16th—18th Centuries (The Case of Upper Silesia)
Authors: Siuciak Mirosława
Published: August 2024

A method of discursive analysis of archival official texts offers a comprehensive view of historical material, much more in-depth than stylistic analyses. The subject of this description are Polish-language official records created in Upper Silesia between the 16th and 18th centuries, illustrating a certain stage of the formation of institutional legal discourse, present in the Polish communicative space since the Middle Ages. The surviving collections represent various types of discourse, determined by the intentions of the people approaching the office and by the role assumed by the institutional entity both in a specific event and in the formulation of a legal written document. The article outlines the two most common discourses in the collections studied: 1. the chancery discourse, that was aimed to produce documentation that would ensure the approaching parties the right to dispose of property in accordance with the established agreements and financial transaction; 2. the judicial discourse, that involved resolving disputes between community members and ensuring public order. The written forms documenting the actions of the court served a mainly informative and reporting function, and their role was extremely important in the current legal system, as they formed the basis for possible appeal proceedings.

Introduction

Cortical lesions can cause major sensory and motor impairments, representing a significant challenge in neuroscience and clinical medicine. Limbal mesenchymal stem cells (LMSCs), renowned for their remarkable ability to proliferate and distinct characteristics within the corneal epithelium, offer a promising opportunity for regenerative treatments. This study aimed to assess whether the transplantation of LMSCs could improve tactile ability in rats with lesions of the barrel cortex.

Methods

In this experimental study, we divided 21 rats into three groups: a control group, a lesion group with cortical cold lesion induction but no stem cell treatment, and a group receiving LMSC transplantation following cold lesion induction. We conducted 3-week sensory assessments using a texture discrimination test and an open-field test. We also performed Nissl staining to assess changes on the cellular level.

Results

Rats in the LMSC transplantation group demonstrated significant improvements in their ability to discrimination textures during the second and third weeks compared to those in the lesion group. The open-field test results showed an increased exploratory behavior of rats in the LMSC transplantation group by the third week compared to the lesion group. Additionally, Nissl staining revealed cellular alterations in the damaged cortex, with a significant distinction observed between rats in the LMSCs and lesion group.

Conclusion

The findings suggest that LMSC transplantation enhances sensory recovery in rats with cortical lesions, particularly their ability to discriminate textures. LMSC transplantation benefits brain tissue reparation after a cold lesion on the somatosensory cortex.

Published: August 2024

Este trabalho objetiva, no entremeio da Linguística Aplicada, da Análise do Discurso Francesa e da Análise Dialógica do Discurso, investigar como se constituem os discursos que circulam na mídia acerca do ensino de culturas estrangeiras em escolas públicas brasileiras. Para tanto, tomamos como corpus um artigo veiculado na internet, em que buscamos compreender os efeitos de sentido que são produzidos sobre o conceito de língua, cultura e ensino; as representações discursivas construídas sobre sujeitos brasileiros e estrangeiros; e as implicações desse discurso midiático para o ensino de línguas e a formação de professores. A partir de nosso gesto interpretativo, foi possível observar que os dizeres acerca do ensino de culturas estrangeiras se sustentam no discurso da inovação, no da interação e no da globalização, produzindo, consequentemente, efeitos de silenciamento da cultura e dos sujeitos brasileiros, bem como o apagamento do caráter tenso que marca o encontro-confronto com o(s) outro(s).

Este artigo tece reflexões sobre a prática tradutória com ferramentas de tradução online (tradutores digitais), partindo do processo e resultados de uma atividade realizada com alunos de graduação em Letras da Universidade Federal de Santa Catarina. Num primeiro momento, apresenta-se um panorama histórico do surgimento da tradução automatizada, enfatizando a diferença entre tradutores digitais e ferramentas de auxílio à tradução (CAT Tools) para, então, discutir o processo de construção de sentidos no texto, considerando-se Bakhtin (2003) e Nord (1991), dificilmente contemplado por essa modalidade de tradução. Uma terceira etapa descreve a atividade realizada em sala, partindo de um texto-referência em língua portuguesa, versado para inglês, espanhol e alemão com o auxílio do Google Tradutor. Da perspectiva funcionalista alemã para os estudos tradutórios, destacam-se as limitações sintáticas, semânticas e pragmáticas das versões produzidas por essa ferramenta, bem como suas implicações para o processo de tradução e para o trabalho do tradutor.

Constituição do sujeito aprendiz, oralidade e livro didático de português: questões a se pensar
Authors: Gaida Winch Paula , Lucci de Angelo Graziela
Published: August 2024

Este artigo visa a analisar como o sujeito aprendiz pode se constituir a partir da oralidade, tendo como referência a teoria Bakhtiniana, e, como corpus de análise, dois exercícios de cunho oral apresentados em um livro didático de português avaliado positivamente, em termos de oralidade (PNLD 2011). Após análise realizada, foi possível verificar que esses exercícios favorecem a formação de um sujeito capaz de utilizar a língua oral em situações públicas formais, diferentemente de seu uso cotidiano, com autonomia, no sentido de atribuir a entonação que julgar apropriada à sua produção oral e de poder assumir uma posição valorativa frente ao enunciado do outro. A oralidade, conforme trabalhada nesses exercícios, promove a interação, entendendo que a constituição de um sujeito aprendiz deve ocorrer de forma intersubjetiva e social, preservando sua singularidade, mediante o diálogo valorativo que estabelece com os demais enunciados, os antecedentes e os posteriores.

Este artigo tem por objetivo mostrar que a homonímia, fenômeno produtor de equívocos na língua, bascula o sistema e produz desordens que, se reconhecidas pelo escrevente-aprendiz, exigem um retorno sobre o que foi dito ou escrito, levando à produção de rasuras. Assim, os conceitos de acontecimento e desordem, propostos por Pétroff (2004) a partir da leitura dos manuscritos de Saussure, mostram-se teoricamente adequados para a análise de rasuras produzidas pela interferência da homonímia. Analisa-se um excerto de diálogo extraído de um processo de escritura colaborativa e inventiva ocorrida em sala de aula, da qual participam duas alunas do 2º ano de uma escola pública. Esta técnica de redação colaborativa favorece a verbalização de comentários, apreciações, justificativas e, sobretudo, reformulações orais referentes ao texto que está sendo escrito. Além disso, a filmagem e sua posterior transcrição permitem o acesso tanto ao registro escrito quanto ao oral e favorecem uma análise linguística mais precisa, em que o oral e o escrito encontram-se imbricados.
Parece que as coisas estão mudando: aos poucos a semântica começa a aparecer nos livros didáticos de língua portuguesa
Authors: Kanyela Fossile Dieysa
Published: August 2024

Neste artigo pretendemos discutir e analisar como tópicos concernentes à semântica são apresentados nos livros didáticos do ensino básico. Trata-se de uma pesquisa em fase inicial, a qual vem sendo desenvolvida por meio do projeto intitulado: "A semântica nos livros didáticos da educação básica" (curso de Letras/UFT/campus de Araguaína). A princípio, oito manuais didáticos estão sendo analisados. A partir do estudo que está sendo desenvolvido, verificamos que o ensino da Língua Portuguesa se dá apartir da Fonética/Fonologia, seguindo para a Morfologia, avançando e estagnando na Sintaxe. Dessa maneira, os resultados parciais sugerem que em alguns manuais didáticos a semântica ainda é discutida de maneira um tanto limitada e vários assuntos são tratados de maneira simples, breve e superficial. Neste artigo, optamos por discutir e analisar, em especial, a coleção Português: Linguagens (volumes01, 02 e 03 do Ensino Médio) de Cereja e Magalhães (2005; 2010), que foi elaborada com base nos Parâmetros Curriculares Nacionais. Esses manuais têm como diferencial possibilitar uma reflexão sobre assuntos destinados à semântica.
Limites Formais e Inscrições: Observador como o Ponto Axiomático em Sistemas Cognitivos
Authors: Diehl Rafael , Maraschin Cleci
Published: August 2024

Neste artigo objetivamos aproximar os limites da formalização em sistemas lógicos, relacionados aos paradoxos da autorreferência, ao uso de inscrições na produção e validação do conhecimento.  A hipótese defendida é a de que a incompletude de tais sistemas está relacionada à questão do observador, pois a consideração de vários níveis descritivos exige a localização de uma cognição corporificada. Tal problemática fica mais emevidencia nos domínios interdisciplinares do conhecimento, pois o diálogo entre modelos de totalização de cada disciplina precisa, paradoxalmente, assumir a impossibilidade de uma visualização total do conhecimento. Conclui-se que as inscrições, numa abordagem sistêmica, devem ser pensadas como interfaces entre experiência e abstração, o que exige considerar as técnicas de representação do conhecimento como local privilegiado de validação e compartilhamento de experiências.
Representações da inteligência feminina na Grécia clássica: Clitemnestra, Jocasta e Antígona
Authors: H. Rosenfield Kathrin
Published: August 2024

Pode-se entender a tragédia como um gênero que reúne formas históricas de pensamento diversas – diferentes estágios do muthos e o logos. Este artigo desvenda como se processa em algumas figuras trágicas femininas uma ruptura significativa com as antigas crenças religiosas. Não é fácil imaginar um mundo no qual os domínios religioso e científico, social e político não estavam separados. Mais difícil ainda é imaginar o desenvolvimento da inteligência e dos méritos cognitivos das mulheres que viviam à sombra dos homens e em grande parte excluídas do domínio público. Este artigo ajuda compreender modulações inovadoras deste imagináriode base.
Do Neutro ao Punctum – em Busca do Grau Zero do Olhar
Authors: Fontanari Rodrigo
Published: August 2024

O presente artigo constitui-se de notas sobre o sui generis conceito barthesiano de punctum, essa alguma coisa que salta do quadro fotográfico e vem perturbar quem o olha. Trata-se, de certa maneira também, de uma tentativa de apresentação do conceito de Neutro, de modo a demonstrar que, no limite, o Neutro é o sentido pungente, por oposição ao studium, aquilo que é “estudado” para comover. Pretendemos, assim, assinalar as afinidades teóricas existentes entre os conceitos de Neutro da escritura e o de punctum da fotografia, tais como Barthes os formulou, progressivamente. Buscamos ressaltar a profunda coerência teórica desse autor, por longo tempo, dado por divagante.
Método de estudio de los deseos y las defensas en el componente icónico del signo visual (ADL-SV)
Authors: Maldavsky David
Published: August 2024

El trabajo comienza aludiendo (primera parte) al valor del signo visual en el intercambio, para  presentar el estado del arte y la propuesta del autor. A continuación el autor se refiere (segunda parte) a los conceptos principales de su enfoque (deseo y defensa), a los instrumentos ya existentes para su detección en diferentes tipos de manifestaciones, verbales y no verbales, y a las categorías de análisis del signo visual (SV): el signo plástico y el signo icónico. Luego el autor alude (tercera parte) a los instrumentos para el estudio de los deseos en el componente icónico del signo visual, para lo cual considera las escenas (acciones o estados), los complementos de tales escenas (objetos, ayudantes, atributos), los desempeños motrices y las distancias en las imágenes. En esta misma parte incluye la descripción de los instrumentos para el estudio de las defensas y los estados en este mismo componente icónico del signo visual. El trabajo termina con unas breves consideraciones sobre el componente plástico del SV, sobre las cuestiones procedimentales en la implementación de los instrumentos y sobre las combinaciones entre diferentes tipos de estudios de la misma imagen.
Letramento em games: o aprendizado na utilização de novos meios
Authors: Audi Gustavo
Published: August 2024

Este artigo tem como objetivo estudar a dinâmica de aprendizado de uma nova mídia e seus impactos no corpo, especificamente relacionados ao letramento em jogos eletrônicos. Considera-se letramento como a habilidade em reconhecer e utilizar a racionalidade gramatical de uma mídia para gerar e consumir conteúdo. Na contemporaneidade, o indivíduo sofre com a constante ação de estímulos midiáticos através de diversas tecnologias, precisando, assim, aprender novas linguagens. Com foco e prática, o cérebro humano consegue se adaptar e reorganizar as redes neurais a fim de produzir sentido com as ferramentas tecnológicas. No caso do videogame, o Tutorial é um período que permite o início desta prática.
THE FIRST CONFERENCE ON THE STUDY OF PRODUCTIVE FORCES IN THE BURYAT-MONGOLIAN ASSR: LESSONS FOR THE PRESENT DAY
Authors: ТУЛОХОНОВ А.К. , МИХЕЕВА А.С. , ЛУБСАНОВА Н.Б.
Published: August 2024

В статье анализируются итоги Первой конференции по изучению производительных сил Бурят-Монгольской АССР, проведенной в г. Ленинграде 1-10 апреля 1934 г. На основе опубликованных материалов конференции авторами обобщены данные о составе ее участников, секциях, характере обсуждаемых вопросов, выделены ключевые итоги. По результатам анализа социально-экономического развития республики определена роль конференции в развитии ее производительных сил. Сделан вывод, что несмотря на существовавшие региональные ограничения (отдаленность территории, слабая заселенность, сложные природно-климатические условия, неоднородность экономического освоения различных зон), сформулированные в ходе конференции рекомендации и последовавшие за ними политические решения позволили превратить аграрную республику в один из крупнейших промышленных центров на востоке страны. Особое внимание уделено важности комплексного решения проблемы размещения производительных сил и их территориальной организации.

The article delves into an analysis of the inaugural conference on the study of productive forces of the Buryat-Mongolian ASSR, convened in Leningrad from April 1 to 10, 1934. Drawing insights from the conference’s published materials, the authors provide a comprehensive overview of participant demographics, sections, discussed issues, and underscore the pivotal outcomes. Through an examination of the socio-economic landscape, we elucidate the conference’s role in steering the development of the republic’s productive forces. Despite regional constraints such as geographical remoteness, sparse population, challenging climatic conditions, and economic disparities across zones, the recommendations arising from the conference, coupled with subsequent political decisions, facilitated the transformation of the agrarian republic into a prominent industrial hub in the eastern part of the country. The significance of a holistic approach to addressing issues of productive force placement and territorial organization is particularly emphasized.
