Background

In most regions and ecosystems, soils are the largest terrestrial carbon pool. Their potential vulnerability to climate and land use change, management, and other drivers, along with soils’ ability to mitigate climate change through carbon sequestration, makes them important to carbon balance and management. To date, most studies of soil carbon management have been based at either large or site-specific scales, resulting in either broad generalizations or narrow conclusions, respectively. Advancing the science and practice of soil carbon management requires scientific progress at intermediate scales. Here, we conducted the fifth in a series of ecoregional assessments of the effects of land use change and forest management on soil carbon stocks, this time addressing the Northeast U.S. We used synthesis approaches including (1) meta-analysis of published literature, (2) soil survey and (3) national forest inventory databases to examine overall effects and underlying drivers of deforestation, reforestation, and forest harvesting on soil carbon stocks. The three complementary data sources allowed us to quantify direction, magnitude, and uncertainty in trends.

Results

Our meta-analysis findings revealed regionally consistent declines in soil carbon stocks due to deforestation, whether for agriculture or urban development. Conversely, reforestation led to significant increases in soil C stocks, with variation based on specific geographic factors. Forest harvesting showed no significant effect on soil carbon stocks, regardless of place-based or practice-specific factors. Observational soil survey and national forest inventory data generally supported meta-analytic harvest trends, and provided broader context by revealing the factors that act as baseline controls on soil carbon stocks in this ecoregion of carbon-dense soils. These factors include a range of soil physical, parent material, and topographic controls, with land use and climate factors also playing a role.

Conclusions

Forest harvesting has limited potential to alter forest soil C stocks in either direction, in contrast to the significant changes driven by land use shifts. These findings underscore the importance of understanding soil C changes at intermediate scales, and the need for an all-lands approach to managing soil carbon for climate change mitigation in the Northeast U.S.

Streptococcus suis is a gram-positive bacterium that causes meningitis, septicemia, endocarditis, and other disorders in pigs and humans. We obtained 42 and 50 S. suis isolates from lesions of porcine endocarditis and palatine tonsils, respectively, of clinically healthy pigs in Japan; we then determined their sequence types (STs) by multilocus sequence typing (MLST), cps genotypes, serotypes, and presence of classical major virulence-associated marker genes (mrp, epf, and sly). The 42 isolates from endocarditis lesions were assigned to a limited number of STs and clonal complexes (CCs). On the other hand, the 50 isolates from tonsils were diverse in these traits and seemingly in the degree of virulence, suggesting that tonsils can accommodate a variety of S. suis isolates. The goeBURST full algorithm using tonsil isolates obtained in this study and those retrieved from the database showed that major CCs as well as many other clusters were composed of isolates originating from different countries, and some of the STs were very similar to each other despite the difference in country of origin. These findings indicate that S. suis with not only different but also similar mutations in the genome have survived in tonsils independently across different geographical locations. Therefore, unlike the lesions of endocarditis, the tonsils of pigs seemingly accommodate various S. suis lineages. The present study suggests that S. suis acquired its diversity by natural mutations during colonization and persistence in the tonsils of pigs.

Scientists have been compelled to search for alternative treatments due to the increasing prevalence of chemoresistance as well as the agonising and distressing side effects of both chemotherapy and radiation. Plant extracts have been exploited to treat various medical conditions for ages. Considering this fact, the main focus of various recent studies that are being conducted to find new and potent anticancer drugs involves the identification and utilisation of potential therapeutic chemicals present in plant extracts. Koetjapic acid (KJA), which belongs to the family of triterpenes, is primarily isolated fromSandoricum koetjape. Ongoing investigations into its therapeutic applications have revealed its tendency to impede the growth and proliferation of cancer cells. Koetjapic acid activates the intrinsic apoptotic pathway and promotes the death of cancer cells. Moreover, it inhibits angiogenesis and the dissemination of tumour (metastasis) by targeting the VEGF signalling cascade. Therefore, this study aims to elucidate the underlying mechanism of anticancer activity of koetjapic acid, providing significant insight into the compound’s potential as an anticancer agent.
Predicting the differences in food security with and without the Russia–Ukraine conflict scenarios over different regions of the world

Published: February 2024

The Russia–Ukraine conflict has caused a global food security crisis, impacting sustainable development goals. Predicting the crisis’s impact on food security is crucial for global stability by 2030. From a macro-perspective, this paper constructs a food security evaluation indicator system and a food security composite index (FSCI), and using the autoregressive integrated moving average model to predict the variations in the FSCI for different regions of the world from 2023 to 2030 under scenarios with or without the “Russia–Ukraine conflict.” By quantitatively analyzing the differences in these variations, the potential impact of the conflict on regional food security is assessed. The results conclude that the global food security level progressively improved over the past 20 years. The FSCI in Europe, Latin America and Caribbean increased at a faster pace than the global average, with growth rates of 0.035/(10 years) and 0.034/(10 years), respectively. However, the FSCI in the Sub-Saharan Africa showed a declining trend. By 2030, it is expected that the Russia–Ukraine conflict will have a significant impact on the food security of Europe and Sub-Saharan Africa, with a contribution of 1.49% and 0.29%, respectively. However, the impact of the conflict on food security levels in Asia and Latin America and Caribbean is relatively small. This study introduces a new quantitative method to assess and project the overall influence of the Russia–Ukraine conflict on food security. The findings contribute crucial scientific support for effectively evaluating and monitoring the sustainable development objectives related to global food security.
Exploring elucidation of red dye mixtures on woolen historical textiles via non-destructive spectroscopic analysis and multivariate cluster analysis

Published: February 2024

One of the foremost challenges facing analysis of historical textiles is that the gold standard technique—high performance liquid chromatography (HPLC)—is inherently destructive. This is especially problematic considering many historical textiles are exceptionally fragile, be it from age, poor care over time, etc. One proposed solution to this is the implementation of non-destructive, namely spectroscopic, techniques, such as diffuse reflectance (Fiber Optic Reflectance Spectroscopy, FORS). In this work, 204 well-provenanced red Norwich textiles were measured with FORS and analyzed to attempt to determine chromophore combinations used to dye the original textiles. To these ends, cluster analysis algorithms and spectroscopic domain knowledge were coupled with selective HPLC validation to assess overall ability of FORS to discern changes in chromophore combinations. It was found that the near infrared (NIR) region of the spectrum contained little meaningful information in multivariate space, while the VIS region, particularly 380–469 nm, showed a narrow visible region that was primarily responsible for clustering behavior that correlates with HPLC-validated samples. This indicates that FORS shows promise for discerning chromophores in textile swatches. Additionally, X-ray fluorescence (XRF) analysis was used to confirm that the observed FORS spectral inflection point shift in the 600 nm region did not correlate with the presence or type of mordant used when dying these textiles. From this work, three main conclusions can be drawn: (1) FORS adequately identifies visual infon, which shows reasonable correlation to HPLC-validated dye recipes, warranting further investigation, and indicating utility for cois or use for those with visual impairments; (2) XRF analysis confirms that the ~ 600 nm inflection point shift and mordant are not correlated when measuring dyed textiles, unless mordant is present below analytical detection limits or not present at all; (3) many documented structural-to-spectral relationships established in the conservation literature are too weak in dyed textiles for statistical analysis and, by extension, expert spectral identification.

Published: February 2024

Purpose

Complications of implant prostheses have direct correlation with the increased use of implants for dental rehabilitation. In this study, we present cases of peri-implant oral malignancies (PIOM) around dental implants and a retrospective analysis of patients treated for PIOM.

Methods

The retrospective analysis was performed with patients treated for PIOM at the Department of Oral and Maxillofacial Surgery of the Seoul National University Dental Hospital between 2006 and 2014. The patient records were thoroughly screened for previous medical issues, human papilloma virus infections, and other clinical data with a focus on relevant information such as localization, time from implant insertion to the development of the carcinoma, implant type and prosthetic rehabilitation.

Results

Twenty-one patients were diagnosed with PIOM. The male-to-female ratio was 1.625. The mean age of the patients was 60.42 ± 9.35 years old. Three patients reported ongoing alcohol/tobacco consumption. Five patients had a history of previous oral cancer surgery or exhibited mucosal lesions. The time from implant placement until carcinoma diagnosis was 49.13 ± 33.63 months on average. Most PIOM patients (95.2%) were diagnosed with SCC. All patients had previously been treated for peri-implantitis. In 85.7% of the patients, prostheses were observed on the opposing teeth where PIOM occurred.

Conclusion

Based on the review of these cases, it can be deduced that there is a possibility that implant treatment and galvanic currents between prosthesis may constitute an irritant and/or inflammatory cofactor which contributes to the formation and/or development of malignant tumors. Patients at potential risk may benefit from individualized recall intervals and careful evaluations.
Reusing finished leather waste to produce pigmented thermoplastic polyurethane composite
Authors: Giehl Diego , Hansen Éverton , Robinson Luiz Carlos , de Aquim Patrice Monteiro
Published: February 2024

Footwear industries generate leather waste during the operation. Some of these wastes contain chromium, which may bring environmental concerns. This study aimed to reuse finished leather waste, the major part of these hazardous wastes, via producing a composite with thermoplastic polyurethane (TPU) for shoe soles. Finished leather waste containing black dyes and pigments was used to color the TPU. The finished leather waste was fragmented, milled, micronized and blended with TPU in a ratio of 10%, 15%, and 20% w/w to produce composite materials. The composite materials were evaluated by morphological and thermal characterizations, physical–mechanical analysis, and environmental tests (leaching and solubilization), which presented that the physical–mechanical and thermal properties were within the standard of shoe soles, and the composites can be classified as non-hazardous. The composites enabled a new way of coloring polymeric matrices and reusing leather waste.

Improving the surface quality of AlMgSi1 alloy with the selection of the appropriate vibration grinding stones
Authors: Engler Carsten , Georgiadis Anthimos , Lange Dirk , Meier Nicolas
Published: February 2024

The number and variety of paints and coating systems in the automotive industry have increased in recent years. However, the basic requirement for the quality of the paints still depends on the surfaces on which they are applied. This applies not only to the large body parts but also to all components that are integrated.

There are many surface treatment processes and techniques that are used as an additional process step, such as pickling for a chemical surface treatment or blasting for a mechanical surface treatment.

The present work investigates a method for optimizing the surface before painting, using the membrane cup of the ultrasonic sensor as an example for AlMgSi1 alloy, without implementing additional process steps.

First, all process steps influencing the surface quality for the production of a membrane cup were considered for optimization. Then, based on a backward process chain analysis, vibratory grinding for deburring of the membrane cup was determined as the process step to be optimized. For the optimization of the vibratory grinding, experiments with two different grindstones were performed. For the characterization of the surface quality, the roughness parameters Rz and Ra were measured with a confocal laser scanning microscope and analyzed in order to determine the optimal process conditions.

The experiments showed that the surface roughness can be significantly improved using dedicated process parameters and taking into account the geometry of the vibratory grinding stones. Moreover, different surface qualities can be achieved at different areas on the workpiece, this new approach provides a solution for surface optimization in various areas of the workpiece without additional process steps and costs.
Sepsis-Induced Coagulopathy: A Comprehensive Narrative Review of Pathophysiology, Clinical Presentation, Diagnosis, and Management Strategies
Authors: Williams Brittney , Zou Lin , Pittet Jean-Francois , Chao Wei
Published: February 2024

Physiological hemostasis is a balance between pro- and anticoagulant pathways, and in sepsis, this equilibrium is disturbed, resulting in systemic thrombin generation, impaired anticoagulant activity, and suppression of fibrinolysis, a condition termed sepsis-induced coagulopathy (SIC). SIC is a common complication, being present in 24% of patients with sepsis and 66% of patients with septic shock, and is often associated with poor clinical outcomes and high mortality.
1,2
Recent preclinical and clinical studies have generated new insights into the molecular pathogenesis of SIC. In this article, we analyze the complex pathophysiology of SIC with a focus on the role of procoagulant innate immune signaling in hemostatic activation––tissue factor production, thrombin generation, endotheliopathy, and impaired antithrombotic functions. We also review clinical presentations of SIC, the diagnostic scoring system and laboratory tests, the current standard of care, and clinical trials evaluating the efficacies of anticoagulant therapies.

Η παρούσα μελέτη εξέτασε, με τη χρήση ημι-πειραματικού σχεδιασμού, την επίδραση των βίαιων ηλεκτρονικών παιχνιδιών στην κατάθλιψη, τον θυμό και την επιθετικότητα στην ύστερη εφηβεία. Το δείγμα αποτέλεσαν 100 έφηβοι, που συμμετείχαν στην πειραματική ομάδα ή στην ομάδα ελέγχου, με κριτήριο την προγενέστερη ενασχόληση με το βίαιο ηλεκτρονικό παιχνίδι PUBG MOBILE. Πραγματοποιήθηκαν μετρήσεις σε δύο φάσεις (πριν και μετά την ενασχόληση με τα παιχνίδια) με τη χρήση των παρακάτω ερευνητικών εργαλείων: (α) ένα ερωτηματολόγιο δημογραφικών στοιχείων, (β) η Κλίμακα Κατάθλιψης του Beck-II (Beck et al., 1996), (γ) η Κλίμακα του Θυμού ως Κατάστασης (Spielberger, 1988) και (δ) το Ερωτηματολόγιο Επιθετικότητας-Σύντομη Μορφή (Bryant & Smith, 2001˙ Buss & Perry, 1992). Η πειραματική ομάδα ασχολήθηκε 15 λεπτά με το προαναφερθέν παιχνίδι στο κινητό τηλέφωνο, ενώ ταυτόχρονα η ομάδα ελέγχου ασχολήθηκε με το μη βίαιο παιχνίδι FIFA Football. Από τα αποτελέσματα της μελέτης αναδείχθηκε η στατιστικά σημαντική αύξηση του θυμού, της λεκτικής και σωματικής επιθετικότητας στην πειραματική ομάδα, αμέσως μετά την ενασχόληση με το βίαιο ηλεκτρονικό παιχνίδι, ενώ δεν παρατηρήθηκε στατιστικά σημαντική διαφορά, μεταξύ πρώτης και δεύτερης μέτρησης, στις προαναφερθείσες μεταβλητές στην ομάδα ελέγχου. Τα επίπεδα της κατάθλιψης παρέμειναν σταθερά και στις δύο ομάδες πριν και μετά την ενασχόληση με τα παιχνίδια. Επιπλέον, διαπιστώθηκε ότι οι ώρες ενασχόλησης με τα ηλεκτρονικά παιχνίδια, η σπουδαιότητα που αποδίδουν οι συμμετέχοντες σε αυτήν την ενασχόληση και η κατάθλιψη αποτελούν προβλεπτικούς παράγοντες της εξάρτησης από τα ηλεκτρονικά παιχνίδια. Τα αποτελέσματα καταδεικνύουν ότι η ενασχόληση με τα βίαια ηλεκτρονικά παιχνίδια αυξάνει τον θυμό και την επιθετικότητα των παικτών βραχυπρόθεσμα και πιο συγκεκριμένα τη σωματική και τη λεκτική επιθετικότητα αλλά όχι την έμμεση.

Heritage Without Heirs: The German Legacy in Serbia. The Case of the Museum of Danube Swabians
Authors: Giergiel Sabina , Taczyńska Katarzyna
Published: February 2024

This article focuses on the first historical museum in Serbia, established in Sombor in 2019 (the Museum of the Danube Swabians), with an exhibition devoted to the presence of Germans in Vojvodina. The artefacts presented at the exhibition, left behind by the Germans who used to live in Vojvodina, have been recognised as part of Serbia’s difficult heritage (the term coined by Sharon Macdonald). The article analyses the permanent exhibition and the museum’s efforts to involve the local residents in creating said exhibition. The article also asks whether the museum in Sombor can shape the collective identity of Serbs and undermine its ethno-nationalist character.
In Search of Female Agency: Latest Trends in Polish Research into Women’s History in Polish Lands in the Nineteenth and Twentieth Centuries
Authors: Sierakowska Katarzyna
Published: February 2024

The article discusses the latest trends in research on women’s history in Poland. Attention is drawn to the increasing number of biographies, and an attempt is made to answer the question of whether and in what direction this type of writing is changing our perception of women’s roles in Polish history. The article discusses the autobiographical literature written by women, whose publications reflect a growing interest in individual history and are a response to the demand to give a voice to previously unheard groups. It raises questions about the role of memoirs in describing past societies and gender order. The role of oral history methods in gaining insight into the past of women and society is also discussed.

An Approximate Dynamic Programming Approach to Dynamic Stochastic Matching
Authors: You Fan , Vossen Thomas
Published: February 2024

Dynamic stochastic matching problems arise in a variety of recent applications, ranging from ridesharing and online video games to kidney exchange. Such problems are naturally formulated as Markov decision processes (MDPs) that are, however, intractable in general. To improve tractability, we investigate the linear programming-based approach to approximate dynamic programming. This approach can provide both feasible control policies and bounds on the MDPs’ optimal policy value, which can be used to establish optimality gaps. However, the approximate linear programs (ALPs) resulting from this approach can often be difficult to solve. To address this computational challenge, we derive novel ALP reformulations that can be used for a broad class of dynamic stochastic matching problems that incorporate, among others, possible match failures and certain restrictions on feasible matchings. We show that these ALP reformulations can be solved efficiently and applied to a broad class of dynamic matching problems. In addition, our numerical results indicate that our ALP reformulations can produce tight bounds that allow us to establish near-optimal policy performance for a broad set of problem instances. Thus, ALP reformulations can present an attractive alternative for applications that involve dynamic stochastic matching.

Published: February 2024

Artificial Water Ponds (AWP) are widely employed for preserving and managing white-tailed deer (Odocoileus virginianus) in arid, and tropical regions of Mexico. However, there is a significant knowledge gap concerning the impact of these AWP on white-tailed deer activity. To determine the effect of AWP on the ecological aspects of white-tailed deer, we assessed the visitation rates and activity patterns of this species in AWP and compared them with areas devoid of water such as Dirt Roads (DR) using camera traps during the dry season within the seasonal wetland region of Nicte Ha, situated in western Campeche, Mexico. The research was conducted in a highly seasonal tropical wetland area at the Nicte-Ha UMA in southwestern Campeche, México. We established set camera trap stations during the dry season of 2019, 2020, and 2021 in seven AWP and 12 DR that operated for at least 80 days and compared the white-tailed deer visitation rate (measured as the Relative Abundance Index, RAI) and activity patterns among both treatments and across the three studied years. We collected a total of 3,640 independent records of white-tailed deer (2,584 in AWP and 1,056 in DR) for three years, with a combined effort of 3,978 camera days (1,306 camera days in AWP and 2,672 in DR). Our analysis revealed that the Relative Abundance Index (RAI) was consistently higher in the AWP than the DR across the three study years. However, we examined RAI variations over the three years and observed differences in the AWP, while the DR exhibited a relatively stable pattern. In the case of the activity patterns, we observed that white-tailed deer were primarily diurnal, with a significant overlap in activity between the two treatment areas. Nonetheless, within the AWP, the species exhibited continuous daytime activity, whereas, in the PR, distinct activity peaks occurred during sunrise and sunset. The results show that the presence of AWP in Nicte Ha has important effects on the presence of white-tailed deer during the dry season since we observed that there is a higher RAI in the sites where there is AWP compared to the PR sites. In the case of activity patterns, the AWP sites maintain constant activity throughout the day compared to DR, where activity peaks associated with sunrise and sunset occur. Our results show the importance that this type of structure has for the management of the species during the dry season of the year in Nicte Ha and the potential benefits of these structures in tropical seasonal areas, especially under a scenario in which drought during the dry season may be more severe in the near future due to the global change.
Applicability of DNA barcoding-based analyses on the diet of the gray brocket deer (Subulo gouazoubira) in xeric hillside forests

Published: February 2024

In this study, we explore the applicability of DNA barcoding, specifically targeting the chloroplast DNA (cpDNA) sequences, particularly the trnL (UAA) intron region, to analyze the diet of gray brocket deer.  This approach offers improved taxonomic resolution and the ability to identify species with greater precision compared to traditional methods.  The study was conducted in the "Reserva Natural Salus" in Uruguay, covering a range of vegetation types, where gray brocket deer coexist with other exotic ungulates.  A local reference database of trnL (UAA) sequences was established, incorporating both GenBank data and sequences obtained from native species in the study area.  Fecal samples were collected in summer and winter, and DNA was extracted and amplified for metabarcoding analysis in pooled samples for each season. For each sample 28,229 and 33,588 reads were obtained respectively, which together corresponded to 25 Operational Taxonomic Units (OTUs).  The species Rubus ulmifolius and Schinus engleri were the most represented in the diet with 69.6 % of the summer reads, whereas in winter, 68.7 % of the reads corresponded only to Schinus engleri.  These findings indicate that gray brocket deer consume species that have higher nutritional value, which may be linked to their capacity to thrive in young and productive ecosystems.  This study demonstrates the feasibility of DNA barcoding for dietary analysis in gray brocket deer and provides valuable insights into their food habits in the "Reserva Natural Salus".  Further improvements to increase the reference databases of native species and the exploration of additional genetic markers are recommended for enhanced species-level discrimination in dietary analysis studies.  This methodology is promising for future research as diet studies have an impact on species management, habitat conservation and biodiversity conservation efforts.
Biogeographic analysis of population density of white-tailed deer in Mexico: Importance of the Protected Natural Areas and Wildlife Management Units
Authors: Sandoval-Comte Adriana , Mandujano Salvador , González-Zamora Arturo , Rodríguez Pilar
Published: February 2024

The white-tailed deer Odocoileus virginianus is the wildlife species with the greatest geographic distribution and economic importance in Mexico.  This article presents a biogeographic analysis of the population density of this deer species by federal states, vegetation types, biogeographic provinces, and field methods, based on 200 selected studies.  Estimates are highly variable and potentially biased due to the different field designs and statistical analyses.  The national average density was estimated at 6.9 deer/km2 (SD = 5.1); specifically, 75.5 % of the estimates were less than 10 deer/km2, and only 5.5 % were greater than 15 deer/km2.  The highest densities were obtained in the northern region by applying the strip transect counts; while estimations using the fecal group count method were more variable and were the most used method in temperate and tropical dry forest regions.  The states with the highest densities were Coahuila, Tamaulipas, Jalisco, Morelos, Michoacán, and Durango.  The highest densities were estimated in the xerophilous scrublands of the northeast, intermediate for temperate, tropical dry, and sub-deciduous forests; and the lowest in the tropical wet forest.  The highest densities were reported for the Tamaulipeca province followed by the Altiplano Chihuahuense, Sierra Madre Occidental, Costa Pacífica, and Depresión del Balsas.  The results of this analysis could guide management strategies for the conservation and sustainable use of this species in extensive UMAs and ANPs, and also to test ecological hypotheses.  However, applying more rigorous field design and statistical analysis is important to obtain confident estimates of population density and other demographic parameters to monitor population dynamics.

Published: February 2024

O presente trabalho tem por objetivo propor uma sequência didática (SD), voltada ao ensino de fisiologia humana na Educação Básica e alinhada às questões étnico-raciais, conforme a Lei 10.639/03. O estudo desenvolvido coaduna com a perspectiva de uma educação científica antirracista e crítica, como defendido por Francisco Júnior (2009), Verrangia e Silva (2010) e Pinheiro e Rosa (2018). Para a elaboração da SD nos ancoramos nos trabalhos de Méheut (2004, 2005) e Méheut e Psillos (2004), focalizados em uma abordagem construtivista de ensino que integra dimensões epistemológica e pedagógica. A SD foi orientada para o ensino sobre a circulação e a respiração humana, por meio da compreensão de uma cardiopatia congênita, a tetralogia de Fallot, e do diálogo com questões étnico-raciais que envolvem um dos protagonistas do tratamento científico desta doença, Vivien Theodore Thomas (1910-1985). Concluímos que é possível desenvolver propostas didáticas, no âmbito das ciências morfofuncionais, capazes de valorizar os conhecimentos científicos produzidos pelos filhos da afrodiáspora.

Authors: Masetto Marcos Tarciso
Published: February 2024

A Didática apresenta possibilidades metodológicas e estratégias de ação docente para orientar o fazer pedagógico e, nesse sentido, é tema essencial nos processos de formação de professores.  Na prática, o que se observa é que a Didática tem sido depreciada, desvinculada das tendências pedagógicas, retrocedendo em muitas conquistas. O objetivo desse artigo é refletir sobre uma nova perspectiva de Didática focada no desenvolvimento educacional e profissional das pessoas através de um processo de aprendizagem que acontece na Aula, redefinida como tempo e espaço de aprender. Trata-se de um ensaio teórico baseado em alguns autores entre eles, Mizukami, Pozo, Sacristán e Gomez, Bain e Autor 1, assim como nas vivências pedagógicas do autor. Ao final se relaciona essa perspectiva de Didática com a formação de professores ressaltando a necessidade de mudança de atitudes de professor e alunos para um processo de aprendizagem.

Published: February 2024

O objetivo deste artigo foi identificar possibilidades para um ensino de ciências antirracista no âmbito das Relações Étnico-Raciais no processo de formação de professores. Para isso, realizamos uma pesquisa-formação na perspectiva de Marie Christine Josso (2004; 2010) e empregamos o caso de ensino a partir da perspectiva de Mizukami (2000) como instrumentos para a produção do dados. Os participantes deste estudo são estudantes de pedagogia da UESB. Como forma de organização dos dados recorremos à análise de conteúdo (BARDIN, 1977). A análise foi efetivada em articulação com os estudos decoloniais e interculturais. Os resultados apontam que o caso de ensino proposto foi importante para a formação dos estudantes, pois promoveu reflexão e autorreflexão acerca de sua prática curricular em articulação com as relações étnico-raciais no ensino de ciências, havendo assim a intenção de promover ações que favoreçam um diálogo intercultural e crítico acerca das diferenças culturais.

Authors: Rodrigues Lillian Ferreira , Herneck Heloisa Raimunda , Euclides Maria Simone , Vieira Terezinha Duarte
Published: February 2024

Este artigo tem o objetivo de apresentar um levantamento acerca das produções bibliográficas referentes à formação para professoras/es da Educação Infantil para a educação das relações étnico-raciais entre os anos de 2012 e 2022. Para isso, realizamos uma pesquisa no formato de estado da arte, que contou com a leitura e a análise dos artigos da Revista da Associação Brasileira de Pesquisadoras/es Negras/os, periódicos da CAPES e da plataforma Scielo, além teses e dissertações da Biblioteca Digital Brasileira de Teses e Dissertações. Constatamos 46 produções bibliográficas referentes à temática do estudo, a partir das quais encontramos a predominância da abordagem empírica sobre a teórica, bem como a incidência de temas recorrentes que situamos em quatro categorias centrais: Processos Formativos, Práticas Pedagógicas, Infâncias Negras e Legislação. Tais categorias se entrelaçam na discussão sobre formação para professoras/es da Educação Infantil para a educação das relações étnico-raciais e se complementam. Diante a constatação de desafios e dificuldades de implementação das Leis nº 10.639/2003 e nº 11.645/2008, observamos uma demanda de estudos voltados para esta especificidade, ao mesmo tempo que nos projeta a necessidade de investimento na educação brasileira com atenção à formação de professoras/es.
DIDÁTICA E EDUCAÇÃO ANTIRRACISTA: CONTRIBUIÇÕES DA CURADORIA DOCENTE PARA A APLICAÇÃO DA LEI 10639/03
Authors: Rodrigues Pereira Lara , Lima dos Santos Bazzo Jilvania
Published: February 2024

Problematizamos o conceito de curadoria, importado do universo das artes para o campo da educação, apresentando algumas possibilidades de atuação dos professores como agentes promotores de mediações artístico-culturais. Escolhemos o cinema como campo de reflexão para a curadoria docente, uma vez que se trata de mídia complexa e linguagem híbrida com acesso e uso recorrente no âmbito escolar. A ideia central corresponde a um contraponto, operado por meio da escola, aos filmes que normalmente circulam e são consumidos pelos estudantes. Ofertar audiovisuais raramente disponibilizados pela indústria de massa é papel da instituição escolar, considerando que tais obras possuem potência crítico-reflexiva para a abordagem dos diversos conhecimentos que são tratados nesses ambientes e cujas gramáticas precisam ser aprendidas. Elegemos discutir, especificamente, sobre a história da escravidão, as resistências e seus desdobramentos, desde o Brasil colonial, por meio do audiovisual A última abolição, construído para além do circuito da indústria de massa, em razão de sua profundidade estética e narrativa, importantes elementos mediadores para o acesso ao conhecimento curricular. Essa pesquisa opera na defesa pela atuação dos profissionais da educação básica como curadores do conhecimento artístico, em especial da linguagem audiovisual, por entendermos que eles/elas podem ser agentes da expansão do repertório artístico-cultural dos/das estudantes.

Published: February 2024

Situational interest is an important factor that has a great influence on learning success in both in-school and out-of-school learning situations. Although there has been extensive research on interest in its diverse forms for decades, an evaluated measurement instrument for situational interest that covers the three theoretically defined components of interest (emotional, cognitive, value-related) is still missing. Therefore, in this study, based on person-object theory of interest, a short scale was developed that can be used in a variety of learning programs independent of content or methods. In study 1, eight suitable items were selected and their structure was examined using exploratory methods. In study 2, the results of study 1 were verified using confirmatory factor analyses. Study 3 shows an example of a practical application of the newly developed scale in two different learning settings. The findings provide evidence that the scale developed here is a practical instrument to measure situational interest taking into account all its components. On the one hand, the scale can help teachers evaluate their educational programs; on the other hand, it can be used by researchers to empirically investigate the construct of interest. Thus, the scale makes an important contribution to research and practice.

The development of green polymers is a crucial long-term solution to address the problem of plastic waste. In particular, the bio-based polymer polyethylene vanillic (PEV) has garnered interest due to its comparable mechanical and thermal properties to polyethylene terephthalate (PET), a widely used single-use plastic. Molecular dynamics (MD) simulations are commonly employed to study the molecular structure and dynamic properties of materials, offering cost-effective applications. However, the accuracy of MD simulation results heavily relies on the chosen force field model. The all-atom (AA) force field, while providing insights into molecular interactions, demands significant computational resources, especially for large systems like polymers. This study aimed to employ the united atom (UA) model with revised OPLS-UA force field parameters for the biopolymer PEV, aiming to reduce computational time in dynamic and physical investigations. Consequently, the UA model successfully folded the PEV polymer in a manner resembling the single-chain PEV treated with the AA model, while also predicting a glass transition temperature (Tg) close to the experimental value of 348 K. These findings underscore the potential of the UA model for simulating PEV and its promising implications.
