Authors: Sánchez-Balsa Alejandro , Sobrido-Prieto María
Published: April 2024

Resumen Introducción La participación social es considerada una de las áreas ocupacionales de vital importancia en las vidas de las personas con esquizofrenia. Por ello, cuando existe una limitación en esta área ocupacional es necesario generar estrategias de intervención que favorezcan y posibiliten el acceso a las mismas. Objetivos Conocer la efectividad de diferentes intervenciones en la participación social en usuarios con esquizofrenia. Método Se realizó una búsqueda bibliográfica en tres bases de datos de ámbito sanitario y social: Pubmed, Scopus y Web of Science Los criterios de inclusión fueron: adultos diagnosticados de esquizofrenia, estudios experimentales publicados en los últimos 10 años en inglés, castellano y portugués excluyendo los artículos de opinión y con menos de 10 participantes. Se seleccionaron un total de 13 estudios. Todos los trabajos fueron evaluados de acuerdo a un checklist. Resultados La intervención más efectiva ha sido la Assertive Community Treatment (ACT), con unos resultados de: mejora en la remisión sintomatológica de 43,98 puntos en comparación el grupo control; en cuanto a los reingresos hospitalarios 19,05%; respecto a la funcionalidad social, ha tenido una mejora de 11,36 puntos; por último, respecto a la calidad de vida ha habido una mejora de 1,40 puntos. Conclusiones La participación social es fundamental en el proceso de rehabilitación psicosocial, de un usuario con esquizofrenia. La ACT ha mostrado mejores resultados de forma significativa frente a la Community-Based Rehabilitation (CBR). Debemos tomar con cautela los resultados obtenidos debido a las limitaciones de este estudio, donde resalta la poca evidencia científica disponible sobre esta temática.
Learning to construct scientific explanations: an analysis of everyday life in the Science classroom
Authors: Carneiro Thalita de Oliveira , Franco Luiz Gustavo , Teles Ana Paula Souto Silva , Matos Santer Alvares de
Published: April 2024

ABSTRACT This paper analyzes how 8th graders proposed and revised explanations for a phenomenon in Science lessons. Guided by Ethnography in Education, we gathered data from observations of the daily life of these lessons and analyzed connections between texts, contexts and events. The results indicate the teacher’s role on the provisional and uncertain character given to scientific explanations; the use of discussions - sometimes in groups, sometimes with the whole class - as a resource through which students validated (or not) their explanations; and the interpretations given by students to the relationships between data and explanations under construction. These resources shaped the practices of proposing/reviewing explanations, which were evidenced by changes in explanatory proposals throughout events. The study offers contributions to the research area of Science Education and implications for pedagogical practice.
“Capitães da Areia” by Jorge Amado and Pierre Bourdieu’s “heretical discourse”
Authors: Valle Ione Ribeiro
Published: April 2024

ABSTRACT The aim of this article is to mobilize interpretative lenses to show how fruitful the relationship with literature can be. The intention is to interweave the (literary and scientific) sensitivities of two intellectuals who left us two decades ago: Jorge Amado and Pierre Bourdieu. The work Capitães da Areia (1937) was the main reference to carry out this analytical exercise, at a moment in which we can observe the upsurge of social, cultural, moral, and doctrinal questions that marked the last century. Besides demystifying the “performative discourse” put into practice by State authorities with the support of the media, Jorge Amado constructs a “heretical discourse”. By presenting a kind of (sociological) portrait of children subjected to social racism, Capitães da Areia is the explicitation of the vulnerability of these children, which involves abandonment, family ties, stigmatization, rootlessness, illiteracy, sexual precocity and virility, the pleasure of risk.

Authors: Freire Eduardo José , Teixeira Aridelmo José Campanharo
Published: April 2024

RESUMO O presente estudo estima os impactos das fusões e aquisições (M&A) no Ensino Superior privado brasileiro no período de 2007 a 2016. Para isso, foram utilizados como base de dados cursos de graduação de instituições de ensino superior privadas. As informações foram coletadas por meio de dados públicos divulgados no Instituto Nacional de Estudos e Pesquisas Anísio Teixeira, bem como no Instituto Brasileiro de Geografia e Estatística. Com uma amostra inicial de 35.324 observações, formou-se um banco de dados em painel sobre o qual se aplicaram duas metodologias: Propensity Score Matching e Diferenças em Diferenças. Os resultados demonstraram que as M&A geram efeitos positivos e estatisticamente significativos para a qualidade acadêmica somente a partir do terceiro triênio, confirmando a hipótese inicial, de que as fusões universitárias, em longo prazo, aumentam as médias dos estudantes no Exame Nacional de Desempenho dos Estudantes.

Authors: Anjos Juarez José Tuchinski dos
Published: April 2024

RESUMO O artigo investiga a institucionalização da escola primária na Província do Paraná do ponto de vista da criança, por meio de egodocumentos produzidos por adultos que, na meninice, frequentaram as escolas da região e, nessas escritas de si, legaram testemunhos sobre suas experiências de escolarização no tempo da infância. O recorte temporal abarca o período provincial paranaense, de 1854 a 1889. Num primeiro momento, analisa as práticas educativas e o papel dos professores primários na institucionalização da escola pública primária conforme percebido pelas crianças que foram seus alunos. Em seguida, investiga a constituição dos tempos escolares como elementos demarcadores de identidade e lugar da escola na vida das crianças e na sociedade paranaense provincial. Conclui-se que a história baseada nos egodocumentos que se pode escrever é a da institucionalização da escola primária num outro nível temporal e social: o vivenciado e percebido pelas crianças
First record of the Southern Platyfish, Xiphophorus maculatus (), (Cyprinodontiformes: Poeciliidae) in coastal streams of Venezuela and implications for conservation
Authors: Rodríguez-Olarte Douglas , Marrero Críspulo Julián , Taphorn Donald Charles , Coronel Jorge Luis
Published: April 2024

Abstract Several fishes of the family Poeciliidae are commonly produced in ornamental aquaculture and also used for pest control, leading to their introduction in numerous countries. Many of these species exhibit tolerance and invasiveness, as exemplified by Xiphophorus maculatus (Günther, 1866). This report documents the presence of X. maculatus in a Caribbean coastal stream in Venezuela. Quizandal Creek has experienced significant human intervention in its lower drainage and channel area. In the final segment of the creek the fish were captured using hand nets and beach seines. The specimens were transported alive to the laboratory for evaluation and subsequently preserved according to standard methods and later were cataloged in the fish collection. 16 males ♂ and 8 females ♀ (16.6-29.4 mm SL. CPUCLA-3630) from the Quizandal Creek, part of the coastal drainage of the Borburata River, were analyzed. This is the first report on the occurrence of Xiphophorus maculatus in natural environments of Venezuela. These coastal streams are situated in a zoogeographic transition zone between regional freshwater ichthyofaunas that have a limited number of species, primarily secondary and amphidromous, which could be susceptible to the presence of introduced species. Xiphophorus fish demonstrate the ability to thrive in highly degraded environments, promoting their dispersion and amplifying the impact on the habitat and local fish, particularly small endemic fish, such as the Rivulidae and Poeciliidae.

Authors: Priyadarshini Nyayapathi Priyanka , Gopamma Daka , Srinivas Namuduri , Malla Rama Rao , Kumar Kolli Suresh
Published: April 2024

Particulate matter (PM) imposes a significant impact to environmental health with deleterious effects on the human pulmonary and cardiovascular systems. Macrophages (Mφ), key immune cells in lung tissues, have a prominent role in responding to inhaled cells, accommodating inflammation, and influencing tissue repair processes. Elucidating the critical cellular responses of Mφ to PM exposure is essential to understand the mechanisms underlying PM-induced health effects. The present review aims to give a glimpse on literature about the PM interaction with Mφ, triggering the cellular events causing the inflammation, oxidative stress (OS) and tissue damage. The present paper reviews the different pathways involved in Mφ activation upon PM exposure, including phagocytosis, intracellular signaling cascades, and the release of pro-inflammatory mediators. Potential therapeutic strategies targeting Mφ-mediated responses to reduce PM-induced health effects are also discussed. Overall, unraveling the complex interplay between PM and Mφ sheds light on new avenues for environmental health research and promises to develop targeted interventions to reduce the burden of PM-related diseases on global health.

Authors: Kumar Mukesh , Kumar Arun
Published: April 2024

This numerical simulation of a roughened solar air heater (SAH) is an investigation of its thermo-hydraulic performance using CFD techniques. The two-dimensional geometry of the SAH, including the absorber plate with roughness elements, is modeled using ANSYS 18. The effects of rib height and rib spacing, on the heat transfer and pressure drop characteristics of the solar air heater are investigated in turbulent flow regions, Re varying between 4000 and 16,000. The numerical simulation provides detailed information on the flow patterns, temperature distribution, and heat transfer rates within the SAH. The results of the simulation show that the decreasing rib spacing and increasing the rib height improve the SAH's ability to transmit heat. The simulation results provide valuable insights into the optimal design parameters for roughened SAHs.

Abstract— Faculty conclaves serve as critical platforms for academic discourse and networking, making them pivotal in shaping the future of educational institutions. These conclaves enable the sharing of best practices and introduction of innovative academic practices. The method of conduct of the faculty conclaves plays important role in their impact on the participants. Hence, it is mandatory to do an impact analysis of these conclaves to analyse the changes created in teaching learning practices. This research paper presents a comprehensive analysis of two consecutive faculty conclaves held in 2022 and 2023 in our institution, aiming to discern the evolving dynamics in teaching among the teachers participated in the same. This study employs a quantitative analysis incorporating surveys and observations to investigate the dynamic created by the faculty conclaves over time. In the first conclave (2022), we identified several prominent themes including Technology enabled Active & Collaborative learning, Experiential learning, innovative assessment, and virtual lab conduct. These discussions laid the foundation for the subsequent year's conclave (2023) with more focused theme of Project Based Learning (PBL), innovative assessment and new initiatives in lab conduct. Our findings reveal a shift towards more collaborative and technologically oriented discussions in the second conclave, emphasizing the importance of adaptability and innovation in higher education. This research highlights the importance of faculty conclaves as spaces for continuous improvement in higher education institutions and underscores their role in responding to the ever-changing educational landscape. Furthermore, the paper discusses the recommendations received in specific teaching areas and thereby creating an insight for the next conclave in year 2024.

Demand for English language proficiency among the engineering graduates with adept digital communication skills is growing in the contemporary global context. Industry 4.0 places English in the center of digital communication. It demands young engineering graduates with digital communication skills in English. This not only places importance of graduates learning English communication skills but also on the teachers to initiate novel pedagogical approaches. It is imperative to initiate these transitions during the students’ graduation stage to ensure their readiness for the industry. The digital teaching and learning in English underscores the need for a fresh pedagogical approach that aligns with the preferences of millennials, facilitating learning across virtual and traditional platforms. Smart classrooms bridge the divides between the teacher and the taught. The evolving landscape of English education calls for a pedagogy infused with technology. Post-COVID, digital pedagogy is supplanting conventional one-on-one teaching methods, integrating techniques like blended learning through Learning Management Systems (LMS), flipped classrooms, self-directed learning, and collaborative approaches. This paper argues for the integration of digital pedagogy in regular classroom teaching and learning in English. The paper suggests that the use of digital media should not stop with the resumption of offline teaching, after COVID, rather should be an integral part of pedagogy in teaching English to engineering graduates. It is believed that digital pedagogy augments learner engagement, fostering active learning. The study underscores the significance and scope of digital pedagogy in the computer-centric era. The present paper represents the findings of the empirical research which sought to compare and contrast the conventional learning mode with blended learning. Keywords: Digital pedagogy; ELT; Engineering graduates; Industry 4.0
Values as a Predicate in Modelling Women’s Careers in the Changing World of Work
Authors: Duda Wioleta
Published: April 2024

The course of women’s careers is a multifaceted issue, conditioned by a range of factors – from economic, social, legal to biological. Whether it is women’s entry into the labour force, their value system, their aspirations or changes in their social position, it is a research perspective for demography, social welfare, family theology, social work, labour economics, social policy or labour pedagogy. All these areas and their determinants are changeable over time, which is reflected in the numerous scientific and research literature and requires constant observation. Work is one of the most important areas of adult life, so careers, their determinants, course and importance for human development are the subject of research interests of various scientific disciplines, including work pedagogy and andragogy. Access to professional work for women and men is still not equal, which implies difficulties in career development. The existing division of occupations into typically female and typically male, the much greater burden of family responsibilities on women, barriers to women’s professional advancement mean that women’s careers proceed differently from men’s and are determined by other factors, including in particular the value system. Objective criteria such as education, competence or work experience are not always a point of reference for both employers and the individuals concerned.
Trends of Professional Training of Masters of Philology in Universities of Poland
Authors: Pyatakova Halyna
Published: April 2024

The article examines various approaches to defining trends in philosophy, sociology, and education. Emphasis is placed on the importance of the trend as a scientific category of comparative pedagogy, which is understood from the position of providing recommendations for the implementation of foreign experience for the development of national education. We analyze educational trends as trends that characterize qualitative changes in the direction of educational development and are directly related to the professional training of Masters in philological specialties. General trends have been identified as typical for the countries of the Visegrad Group throughout all stages of the development of higher education in the participating countries, but their manifestation is related to the development of the entire European higher education. We consider leading trends to be trends that are decisive at a certain stage of the development of higher education and can be both common and different. Education reforms started in Poland earlier than in other W4 countries. Attention is paid to the analysis of such modern educational trends in the professional training of masters of philological specialties in Polish universities, such as: the introduction of information and communication technologies, the formation of competencies as the results of Master’s studies, the implementation of pan-European recommendations on language education; formation of EVO as a standard of knowledge about Europe; development of international cooperation of universities as a proces of internationalization of education, participation in academic mobility. It was concluded that the process of reforming higher education in Poland is characterized both by trends associated with changes under the influence of provisions, EC documents and the Bologna reform, and by those that appeared in the process of formation of B4. Conceptual trends in the professional training of masters in philology, which each B4 country takes into account in order to preserve its national education, are also important for Polish education.

Authors: Karkach Andrij , Semigina Tetyana , Kravchenko Oksana
Published: April 2024

In this article, we present the outcomes of implementing an experimental program designed to nurture digital proficiencies among older adults within the framework of a Third Age University affiliated with a territorial social service center. Through a process of analytical scrutiny, we have refined, systematized, and extended the definitions and structure of digital proficiencies in the older demographic. Anchored in this conceptualization and the tenets of andragogy, we have formulated a program that prioritizes the enhancement of digital skills, encompassing computer utilization, internet navigation, engagement with social media, and the mastery of other digital tools. Furthermore, the research delves into the collaboration between social workers who specialize in geragogy and program participants, as well as the utilization of the Moodle platform. The analysis of survey results (n=360 respondents) substantiates the program’s triumph and the favorable attitude of older adults toward digital technologies. It underscores how the program takes into account the nuances of geronto-educational technologies while fostering the digital proficiencies of older individuals, enabling them to seamlessly integrate digital tools into their everyday lives.

Objetivo. Analizar los métodos de acumulación y asignación de costos utilizados en la práctica empresarial. Metodología. Para el levantamiento de información se utilizaron cuestionarios, entrevistas semiestructuradas, revisión documental y observación directa.Resultados. Los resultados confirman la utilización de técnicas de medición tradicionales por parte de la empresa objeto de estudio. Sin embargo se evidenció un método de asignación de costos indirectos que soluciona el problema de los métodos de asignación de tasa única, conjugando dos factores volumen y tiempo, la cual culmina en una nueva fórmula propuesta.Conclusiones. El estudio concluye que la utilización de una tasa de asignación de costos indirectos basada en rendimiento de manera inversamente proporcional permite que aquellos productos que significaron un mayor esfuerzo —al obtener un volumen de producción menor por hora consumida— asuman una mayor parte de los costos indirectos de fabricación y viceversa, por lo cual propone una nueva fórmula para la realización de esta asignación que se explica de manera práctica para enriquecer la teoría existente.

Published: April 2024

The present study analyzed the dynamics of the formation and disposal of construction waste in the Russian Federation and Sverdlovsk region in 2016–2021. A comparative assessment of the amount of construction waste at ownerless facilities in the Sverdlovsk region was performed. It was established that the amount of accumulated construction waste at ownerless facilities significantly exceeds the amount reported annually at the end of the year. An album of standard technological solutions for the implementation of "pilot" construction and municipal projects in Russian regions was proposed. Accordingly, as part of the album, a territorial scheme for construction and municipal waste management, as well as disposal technologies that have passed the ecological and hygienic safety assessment were presented. Recycling products include building materials (sand-gravel mixture), soils, ecological black earth. The approach to the assessment of waste disposal technologies is characterized, taking into account not only an environmental perspective, but also human health safety. The findings can be used by regional and local authorities, investors in the field of cleaning of populated areas.
Purification of process solutions from mercury by sorption
Authors: Zelyakh Ya. D. , Timofeev K. L. , Voinkov R. S. , Maltsev G. I. , Shunin V. A.
Published: April 2024

At JSC «Uralelectromed», selenium-containing raw materials and industrial products are processed, resulting in solutions containing a mixture of mercury with concentrations as follows (g/dm3): 157–210 Se; 0.004–0.02 Hg; 0.15–0.20 Te; 2–3 As; 0.15–0.20 Sb; and 45–50 S. To produce branded selenium, the mercury concentration in the solution must be kept below 0.001 g/dm3. Various methods, such ashydrometallurgical and electrochemical processes, are known for mercury purification from solutions. JSC «Uralelectromed» has selected sorption technology for mercury removal using the weak-base macroporous anionite Lewatit MP-68 (Germany), which allows for control over the degree of solution purification. In pursuit of import substitution for the Western European sorbent Lewatit MP-68, we investigated several pre-selected industrial sorbents for extracting mercury anionic complexes produced in Russia (AM-2B, AN-31, AV 17-8, VP-3Ap), China (Seplite MA 940 and LSC 710), and India (Tulsion CH-95 and CH-97). Initially, in static mode, we determined the distribution coefficient (Cd), the degree of element extraction (ε), the static exchange capacity of the resins (SEC, g/dm3), and the mercury/selenium separation coefficient (DHg/Se) which led to the selection of the best samples: AV 17-8, Seplite MA 940, AM-2B, and CH-97, with SEC values of 0.95–0.97 g/dm3 (SEC = 0.98 g/dm3 of resin Lewatit MP-68). Subsequently, in dynamic mode, we ranked the ionites by decreasing dynamic exchange capacity (DEC / TDEC): AV 17-8 ≥ Lewatit MP-68 > AM-2B > Seplite MA 940 > Tulsion CH-97. Resins AV 17-8, Seplite MA 940, and AM-2B demonstrated similar dynamic sorption characteristics; under comparable conditions, mercury breakthrough occurred after processing at least 950 specific volumes of the initial solution. In contrast, with Lewatit MP-68 ionite, mercury breakthrough occurred after no more than 750 specific volumes, indicating the need to increase the number of sorption steps in the solution purification cascade. Considering the totality of ion-exchange properties, for further industrial testing, it is recommended to use the domestically produced resin AV 17-8 instead of the foreign sorbent Lewatit MP-68 in the sorption purification process of selenic acid to remove mercury, thereby ensuring the production of branded selenium.
Impact of ECAP at 300 °C on the microstructure and mechanical properties of the quenched Zr–2.5%Nb alloy
Authors: Gunderov D. V. , Stotskiy A. G. , Gunderova S. D. , Aubakirоva V. R. , Demin A. Yu.
Published: April 2024

We investigated the microstructure of the Zr–2.5%Nb zirconium alloy after subjecting it to equal-channel angular pressing (ECAP) and found that ECAP at 300 °C increases the strength by 140 to 180 %. Notably, unlike other studies, our alloy did not show complete dissolution of niobium particles, which may be due to the reduced diffusion rates at the lower deformation temperature of 300 °C. Pre-treatment involving quenching before severe plastic deformation was also studied, which developed a lamellar structure introducing additional boundaries that facilitated grain refinement during subsequent ECAP. The strength of the alloy was further enhanced by solid-solution hardening, achieved through the complete dissolution of the Nb particles into the matrix post-quenching. This process resulted in a 2.3-fold increase in yield strength after quenching plus ECAP compared to the initial coarse-grained state.

Authors: Revilla Ursula S. , Peña-Claros Marielos , López-Mendoza Rey David , Meave Jorge A. , Bongers Frans
Published: April 2024

Background: Individual pioneer tree species often dominate early tropical dry forest succession and thereby affect possible successional pathways. Mimosa acantholoba var. eurycarpa is a highly dominant species in the tropical dry forest in Mexico.
Hypothesis: Mimosa acantholoba var. eurycarpa exerts an inhibitory effect on the germination, establishment, survival, and early growth of light-demanding pioneers, while facilitating these processes for shade-tolerant old-growth forests species.
Studied species: Lonchocarpus torresiorum, Lysiloma divaricatum, Mimosa acantholoba var. eurycarpa and Vachellia farnesiana.
Study site and dates: Nizanda, Oaxaca, Mexico, 2020-2021.
Methods: In 12 early successional plots, we applied three levels of crown cover removal (100, 50, and 0 %) of established trees of the dominant pioneer legume (M. acantholoba var. eurycarpa). We sowed seeds of the four study species in each experimental plot and recorded their germination, establishment, survival, and early growth over a 2-mo period.
Results: The removal of crown cover of established M. acantholoba var. eurycarpa trees did not significantly affect germination. Lysiloma divaricatum had the highest germination probability, the fastest germination, and the highest establishment probability regardless of treatment. Lonchocarpus torresiorum had the highest establishment probability in plots where the crown cover of established M. acantholoba var. eurycarpa trees was removed The survival probability of both shade-tolerant species was highest in the 100 % removal treatment.
Conclusions: Despite successful germination of shade-tolerant species, their survival is inhibited under the dense canopy of the dominant legume. Therefore, interventions to reduce the crown cover area of this dominant legume may stimulate forest recovery.

In food industry, fermentation is defined as the process of converting organic substances into acids, ethanol or carbon dioxide. These substances are capable of suppressing the growth of pathogenic microorganisms in the products. The main substrates used in the production of fermented foods are milk, meat, fish, cereals, fruits, vegetables and beverages. Currently, fermented foods and beverages are considered as a part of daily diet. Our current research results showed that the fermentation temperature, sugar concentration and carrot juice concentration affected the dry matter content and sensory properties of the finished drink. The maximum amount of dry substances was noted in the beverage samples obtained at a temperature of 25°C with a content of 10% sucrose, fermentation time of which was 24 hours. After 48 and 72 hours of fermentation, the dry matter content decreases by 0.5 and 1%, respectively. The most optimal samples in terms of taste and dry matter content were samples of a drink containing 10% sugar and 10% carrot juice, fermented at a temperature of 25°C for 48 hours, while the shelf life of the drink, taking into account the survival of microorganisms, was 5 days.

Побеги лапчатки кустарниковой привлекают внимание исследователей вследствие широкого спектра фармакологической активности. Анализ научной литературы показывает наличие у сырья противовоспалительного, кровоостанавливающего, ранозаживляющего, иммуномодулирующего действия. Однако в РФ лапчатка кустарниковая используется только в пищевых целях, а показатели ее качества нормируются в соответствии с рекомендациями ТУ 9198-445-376764592016 «Напитки чайные». Авторами проведено изучение влияния ряда факторов на извлечение из сырья веществ полифенольной природы. Проведенное исследование позволило определить оптимальные параметры для получения извлечений из побегов лапчатки кустарниковой и рекомендовать условия проведения экстракции при гидромодуле 1:10 спиртом этиловым 45% в течение 60 минут, что позволяет добиться максимального выхода веществ полифенольной природы.
