Betaone is a variety of barley developed by the Korea Rural Development Administration. This study investigated the anti-osteoporosis effects of Betaone barley water extract (B1W) on ovariectomy (OVX)-induced bone loss in mice. To elucidate its mechanism, the effect of B1W on osteoclasts was assessed by measuring the protein expression of nuclear factor-activated T cells c1 (NFATc1), the expression of genes involved in osteoclast differentiation, and bone pit assays. B1W (300 mg/kg/day) significantly increased bone mineral density and bone volume fraction, but decreased trabecular separation compared to the OVX group. B1W also showed a trend towards decreasing serum C-telopeptide of collagen type 1 levels in OVX mice. Additionally, B1W reduced the expression of NFATc1 and downregulated the mRNA expression levels of various marker genes such as c-Fos, tartrate-resistant acid phosphatase (TRAP), cathepsin K (CTSK), dendritic cell-specific transmembrane protein (DC-STAMP), and osteoclast-associated Ig-like receptor (OSCAR). B1W reduced the osteoclast activity in the receptor activator of nuclear factor-κB ligand (RANKL)-treated osteoclasts by inhibiting the mitogen-activated protein kinase (MAPK) pathway. Based on the results, B1W can be considered a useful candidate for a therapeutic agent for treating conditions of bone loss and could also be used as an ingredient in health supplements.

Published: February 2025

Objectives

Ultrasound (US) measurements of diaphragmatic excursion (DE) are widely used to provide a non-invasive assessment of the diaphragmatic function at the bedside, especially in intensive care. However, this measurement has never been validated against a less operator-dependent technique such as MRI. Dynamic MRI is the only imaging modality that creates a four-dimensional reconstruction of the diaphragm. The primary objective of this study was to assess the agreement between DE obtained using dynamic MRI with those obtained using ultrasound. The secondary objectives were to define DE thresholds for the diagnosis of DD using MRI and to compare the performance of US and MRI to diagnose DD.

Methods

Prospective single-center study in which consecutive outpatients referred for a dynamic thoracic MRI were included. This study was conducted at a university hospital in Paris, where there was daily access to ultrasound (US) and extensive expertise in diaphragmatic MRI The DE of each hemi-diaphragm was measured sequentially using ultrasound and MRI in random order, during spontaneous breathing (SB) and forced inspiration (FI) by independent observers blinded to each other. We analyzed the agreement between DE obtained using US and MRI for each hemi-diaphragm.

Results

We enrolled forty-five patients, aged 58 ± 36 years, of which twenty-eight (68%) had a confirmed DD. During SB, the mean bias for DE measurement was −3.8 mm, 95% CI [−7.1; −0.6] for the left hemi-diaphragm, and 1.0 mm, 95% CI [−3.5; 5.5] for the right hemi-diaphragm. Limits of agreement (millimeters) were [−25; 17] on the left side, and [−28; 30] on the right side. MRI threshold values for DE defining dysfunction were 11 mm for quiet SB, and 38 mm for FI. These thresholds had a sensitivity of 77.7% and a specificity of 77.4% during SB, with an AUC of 0.86.

Conclusion

US and MRI provide different values for DE, probably because the measurements were not obtained exactly at the same localization. Nevertheless, diagnostic performances of MRI and US to recognize DD appeared comparable.

Authors: Craig Adam T. , Lawford Harriet , Miller Maggie , Chen-Cao Liuyi , Woods Leanna , Liaw Siaw-Teng , Godinho Myron A.
Published: February 2025

Background

Healthcare providers are critical to the successful, sustainable and impactful implementation of digital health. Despite the growing interest, Digital Health Innovations (DHIs) are often implemented without sufficient evidence, leading to numerous short-lived projects and a limited understanding of their impact on health systems and outcomes. In 2023, the World Health Organization (WHO) introduced a new Classification of Digital Health Interventions, identifying four core DHI user groups. This review aims to synthesise evidence on the impact of DHIs designed for one of these user groups—healthcare providers—on delivering health services in low- and lower-middle-income countries (LLMICs).

Methods

We will conduct an umbrella review, analysing systematic reviews on DHIs for healthcare providers. Data will be extracted using deductive coding before being thematically analysed according to the 11 DHIs for service providers outlined in the WHO’s 2023 Classification.

Discussion

This umbrella review will explore, synthesise, and evaluate the quality of evidence on how healthcare providers in LLMICs utilise DHIs to address service delivery challenges and their effectiveness. To our knowledge, this is the first comprehensive synthesis of evidence focused on DHIs designed for use by healthcare providers in LLMICs. It is also the first review to align with WHO’s taxonomy for DHIs, as outlined in the WHO Classification of Digital Interventions, Services and Applications in Health.

Systematic review registration

The protocol is being registered in PROSPERO (ID: CRD42024586285).

Authors: Zhu Yanfeng , Li Zheng , Li Tianyi , Jiang Lei
Published: February 2025

Using text analysis techniques to identify the research topics of the literature in the field of cybersecurity allows us to sort out the evolution of their research topics and reveal their evolution trends. The paper takes the literature from the Web of Science in the field of cybersecurity research from 2003 to 2022 as its research subject, dividing it into ten stages. It then integrates LDA and Word2vec methods for topic recognition and topic evolution analysis. The combined LDA2vec model can better reflect the correlation and evolution patterns between adjacent stage topics, thereby accurately identifying topic features and constructing topic evolution paths. Furthermore, to comprehensively evaluate the effectiveness of the LDA model in topic evolution analysis, this paper introduces the Dynamic Topic Model (DTM) for comparative analysis. The results indicate that the LDA model demonstrates higher applicability and clarity in topic extraction and evolution path depiction. In the aspect of topic content evolution, research topics within the field of cybersecurity exhibit characteristics of complexity and diversity, with some topics even displaying notable instances of backtracking. Meanwhile, within the realm of cybersecurity, there exists a dynamic equilibrium between technological developments and security threats.

Published: February 2025

Obesity, type 2 diabetes mellitus (T2DM), and related metabolic disorders occupy the leading positions on the lists of diseases worldwide. It is not surprising that the efforts of many scientific groups and clinicians are aimed at finding effective therapeutic strategies to treat these diseases. In recent decades, the involvement of the intestinal microbiota in the pathogenesis of metabolic, immune, and other disorders in humans has become increasingly obvious. In this regard, attempts are made to modulate the composition and functional activity of the microbiota as a primary or adjuvant way of treating various disorders. The purpose of this review was to highlight and analyse the results of clinical studies in recent years devoted to the study of various methods of modulating the intestinal microbial community for the treatment of obesity, metabolic syndrome, and T2DM. To achieve this goal, we conducted a systematic search using electronic databases, including Scopus, Medline, and PubMed, limiting the publication period from 2019 to 2024. The conducted analysis showed that the therapeutic success of various methods of modulating intestinal microbiota, on the one hand, indicates the need to take into account the characteristics of the microbial composition of the intestines of patients and direct therapeutic actions to correct dysbiosis; on the other hand, it provides grounds for the widespread introduction of pharmacological or other approaches to correcting the microbiotic composition of the intestine as an effective method of treating obesity and associated metabolic disorders.
Efficacy and safety of sodium-glucose cotransporter-2 inhibitors in type 2 diabetes mellitus with inadequate glycemic control on insulin: a network meta-analysis
Authors: Shestakova M. V. , Galstyan G. R. , Kvasnikov B. B. , Erina E. E.
Published: February 2025

The increase in the number of patients with type 2 diabetes mellitus (T2D) and mortality among them forces us to look for ways to optimize T2D treatment. At the same time, more than half of patients with an established diagnosis do not reach the glycemic targets and require intensification of therapy. Due to the progressive deterioration of the glycemic status, almost one in five T2D patients requires insulin therapy (IT), and over time, IT intensification with titration of the dose of insulin. This approach is limited by a few adverse effects such as: an increased risk of severe hypoglycemia, weight gain, decreased sodium excretion, which means fluid retention in the body, and the patient’s unwillingness to carry out complex therapy regimens. The addition of sodium-glucose cotransporter 2 (SGLT2i) inhibitor with an insulin–independent mechanism of action to the treatment is aimed to solve the problem of optimizing glycemic control in this category of T2D patients. The purpose of this network meta-analysis (NMA) was to indirectly compare the efficacy and safety of SGLT2 inhibitors added on top of insulin in T2D patients. The analysis included randomized clinical trials in which dapagliflozin, empagliflozin, ipragliflozin, luseogliflozin, and ertugliflozin were prescribed as SGLT2i. The primary endpoint was a change in glycated hemoglobin (HbA1c), and the secondary endpoints were changes in a mean of fasting plasma glucose, body weight and blood pressure, as well as the mean change in daily dose of insulin. The analysis of safety data included a comparative assessment of the incidence of hypoglycemia, reproductive tract and urogenital infections, and hypovolemia. The results of the conducted NMA demonstrate the comparable effectiveness of various SGLT2i regarding managing of glycemic status in T2D patients receiving insulin, along with commensurate safety and tolerability of therapy.

Cracking the code of change in EU legal discourse: signifying practices shaping inclusion for vulnerable in the digital age
Authors: Notari Fabiola
Published: February 2025

The initiative of the Clear Writing Movement (Kimble 1992), targeting the democratization of communication by simplifying legal documents, has influenced the presentation of law globally. By uniting diverse philosophies of Plain Language and Easy-to-Read under the broad umbrella of text clarity and accessibility (Maaß 2020), this movement has particularly influenced the European Union’s linguistic policy (Foley 2002; Nerelius 2014; Seracini 2019). Notwithstanding this progress and the accelerated shift towards digital transformation during the Covid-19 pandemic, the European Union’s efforts to enhance its communication for vulnerable groups (European Union 2013) remains under-examined. This research, leveraging corpus linguistics and multimodal analysis, aims to systematically uncover foundational values and thematic clusters embedded in EU legal and policy documents related to the social inclusion and rights of vulnerable populations. It explores how these are dynamically communicated through easy-to-understand multimedia resources produced by Inclusion Europe and the European Commission (Bernabé 2020). Findings underscore the pivotal role of digital technology in revolutionizing the creation and interpretation of legal documents, reflecting the European Union’s proactive efforts to forge new avenues for multimodal legal communication marked by innovative signifying practices. The research concludes by emphasizing the socio-semiotic and context-specific dimensions of legal discourse. Far from being merely universal and abstract, it can be adapted and reshaped to reflect societal and political stances on regulated issues. This can foster a sense of belonging, empowerment, and inclusivity within vulnerable communities, while also nurturing broader societal cooperation and understanding.

Authors: Balkrishnan Rajesh , Selden Owen , Rusingiza Emmanuel
Published: February 2025

The purpose of this review is to provide an overview of Rwanda’s healthcare system, an understanding of the infrastructural challenges and barriers to accessing care for Rwandans, and areas where Rwanda has made progress in its healthcare system. We examined the literature published on Rwanda’s healthcare system and social determinants of health. We analyzed government data over the past fifteen years to understand the progress that the healthcare system has made. We developed criteria for selecting articles for our review. The rebuilding of Rwanda’s healthcare system was done through community-based healthcare, government insurance, and a robust public health system. The public health system was built on private-public partnerships, community-based health workers, and international partnerships, like Human Resources for Health. While Rwanda continues to improve its healthcare system, the urban-rural divide, human resource constraints, and challenges with system infrastructure are consistent issues which plague it. Altogether in the aftermath of one of the most horrific genocides in recorded history, Rwanda’s progress serves as a beacon of hope and model for capacity-building.

Authors: DROBOTUN O. , PROTSENKO V. , TERNOVYY N.
Published: February 2025

Background. Bone neoplasms significantly reduce the patient’s quality of life (QoL) not only during the manifestation of the primary disease but also at various treatment stages. Aim. To study the QoL indicators in patients with primary malignant bone tumors before and after surgical treatment using a training 3D model. Materials and Methods. 44 patients with primary malignant tumors of the lower extremities (osteosarcoma and chondrosarcoma) were treated by surgery. 3D modeling was used to plan the surgical intervention. 3D printing of the models of the pathological foci was performed by the method of layer-by-layer deposition (Fused Deposition Modeling, FDM) using a Creatbot D600 3D printer. The QoL index of patients before and 3 weeks after surgical treatment was measured by the arithmetic sum of the scores of the QLQ-C30 simplified version questionnaire. Results. The surgical removal of a tumor using a training 3D model had a positive effect on the QoL of patients. Before treatment, the QoL index was on average 7.4 ± 1.2 points, and after treatment 9.4 ± 1.3 points, that is, by 27% higher. Conclusions. The use of training 3D models not only implements a strategy of personalized treatment and improves the QoL of patients but also contributes to optimization of the postoperative rehabilitation.

Authors:   Institute of Software Systems NAS of Ukraine, Grishanova I.Yu. , Rogushina J.V. ,   Institute of Software Systems NAS of Ukraine
Published: February 2025

We analyze dynamic programming and machine learning algorithms (on example of Q-learning) used for automatic adaptive composition of web services based on service quality assessments, their input parameters and work specifics. Software implementation of these algorithms on sets of services of different volumes is developed for comparison their performance parameters.

We determine that the considered methods allow finding the optimal set of services only for composition with a predefined fixed-length route. This restriction causes a need to generalize the problem formulation for an arbitrary set of service classes in the composition route. On base of the performed analysis, we developed an algorithm that solves this problem of building a composite service with a route of arbitrary length (using the Q-Learning method), that has the best overall quality ratings. A software implementation of both this algorithm and other algorithms for solving this problem (genetic algorithm, greedy search, dynamic programming, SARSA, etc.) are developed to compare the speed of their work and the evaluation of the resulting composite service on data sets of different volumes.

This paper proposes the multi-stage process of delivering the forecast data to end-user mobile device. The initial task here is to collect the historical weather and air pollution data. After that, the following steps should allow to build the forecasting infrastructure: the input-output model should be defined for regression task, the machine learning algorithm should be trained and its hyperparameters should be optimized, this forecasting model should be serialized to file and it should be used to create the publicly available web-service, the mobile device should have the application installed that would be querying the forecast data from the service and would be displaying the multi-parameter chart on the screen.

The proposed concept of user-centric distributed application covers the following three pillars of this architecture: machine learning model, containerized web-service and user interface application on mobile device. The Python-based libraries Numpy and Pandas were used to prepare the dataset, the Scikit-learn library and Histogram gradient boosting algorithm were leveraged to build the machine learning model. Here are the technologies employed to build the web-service: Docker, Kubernetes, FastAPI and BentoML. The Google Flutter platform was used to build the application for mobile devices.

A quantitative model of fluids’ dynamics (MFD) in the human body is created. Initially, MFD was realized as an autonomous C# software module (SM) functioning under given dynamic input characteristics. Later, SM was incorporated into our special software-modeling tool (SMT) capable of simulating the main modes of the human physiological super-system (PSS) providing cells' life. MFD describes mechanisms regulating long-term blood, lymph, total cells’, and intercellular volumes. SMT simulates both intracellular and multicellular mechanisms providing cell energy balance despite casual dynamics of energy consumption rate. Multicellular mechanisms include complex systems controlling systemic and regional hemodynamics, interaction of the liver with the pancreas, blood filtration in kidneys, bladder function, and liquid expirations in lungs and skin in the background of a dynamic external environment. The latter is a gas atmosphere with altering pressure, illumination, temperature, humidity, and wind speed. Models have been tested using algorithms that design scenarios, including simulation of either short-time or long-time (hours or days) observations. Input data include different combinations of internal and external parameters including osmotic, and oncotic pressures. Output data include the main parameters characterizing organs and life support systems. Both student-medics and physiologists interested in providing theoretical research can be users of SM.

Published: February 2025

The article describes the concept of functional sustainability of intelligent systems in decision-making as one of the main aspects in the creation of methods for formalizing and modelling knowledge and the possibility of using it for decision support in the energy sector.The concept of functional stability was introduced for dynamic objects. However, for intelligent systems this concept is significantly different.This is due to the fact that the functioning of intelligent systems cannot be considered as the movement of an object. The functions of artificial intelligence for the creation of intelligent systems in the energy sector to support strategic decision-making on energy development, taking into account the requirements of energy security, are formulated. The use of the principles of situational management corresponds to the general scheme of research on the problem of energy security and strategic decision-making related to the assessment of the state of energy facilities and the fuel and energy complex as a whole, as well as the choice of the main directions of their further functioning and development. The article defines the parameters of functional sustainability of intelligent systems in decision-making and formulates the main characteristics of reliability, stability and survivability of intelligent systems, presents in graphical form the main aspects of functional sustainability of intelligent systems in decision-making, reflecting the basic concepts of situational management, including situational analysis and situational modelling from the perspective of studying the problem of energy security. The formulated concept of the functional sustainability of intelligent systems makes it possible to create algorithms for further use in the development of software for research and support of decision-making solutions in the energy sector.

У статті здійснено спробу дослідити жанрові домінанти есею в мемуаристиці Юрія Шевельова. Проаналізовано сучасні концепції жанру есею й встановлено, що завдяки синкретичності та пластичності есей стає окремою формою інтелектуального осмислення буття, породжуючи цілий пласт текстів із вираженими метажанровими ознаками. Розглядаючи стратегії есеїстичного письма, науковці наголошують на його наративно-ментативній природі та заміні ролі наратора екзогітатором. Визначено, що домінантними есеїстичними рисами мемуаристики вченого є самоідентифікація та індивідуально-авторське начало, зреалізовані через комунікативні стратегії авторефлексії, коментування та аргументації. Це дає можливість простежити етапи кристалізації національної ідентичності автора та зрозуміти мотиви його вибору. Категорія автора «створюється» в тексті самим текстом через відтворення його ставлення до навколишньої дійсності. Наративно-ментативна природа тексту спогадів, окрім звернення до стратегії коментування, для розкриття авторської позиції, реалізується завдяки асоціативним зв’язкам, суб’єктивним за природою, та відображає процес формування авторської думки «на очах у читача».Особливою рисою реалізації самоідентифікації в мемуарах Ю. Шевельова є її проєкція крізь призму пошуку «своєї території», де автор оприявнює «власну територію», шукаючи важелі самовизначення через неї. Уточнено, що «своя територія» — це не обовʼязково географічне поняття, хоча топографічні акценти неуникненні та є важливими в цій самоідентифікації. Встановлено, що концепт «своя територія» в есеїстиці вченого зреалізований через інтерпретацію англійського слова «privacy». Презентація себе через обраного носія висловлювання як жанрова ознака есею в мемуарах Ю. Шевельова здійснена за допомогою свідчень автора щодо свідомого обрання псевдонімів (Ю. Шерех, Гр. Шевчук).

végeztünk.

A magas roma tanulói arányú iskolákban gyakoribb a roma pedagógus
foglalkoztatása, de alacsonyabb a szülői bevonódás. A roma pedagógust
foglalkoztató iskolák nagyobb kihívásokkal néznek szembe, ugyanakkor inkább
támogatják a tanulók hátrányainak leküzdését. A roma pedagógus jelenléte fokozza
(a szülők szűkebb körét elérő) szülői bevonódás hatását a fegyelemre nézve. A
roma tanulók aránya mentén eltérő mintázatokat látunk.
Physiocracy: Liberalism and Despotism
Authors: Pimenta Tomás Lima
Published: February 2025

Abstract This paper offers an account of Physiocracy’s ideal of legal despotism. It does so by pursuing three argumentative lines. First, it offers a definition of liberalism to then distinguish two traditions in modern liberalism. Subsequently, it argues that Physiocracy is an heir to modern natural law and constitutes a crucial step in mutating the juridical conception of natural law into an economic understanding. Next, it examines the concept of legal despotism. For this purpose, it elucidates the meaning of absolutism in early modern political thought and the significance of the concept of despotism by comparing it with the Aristotelean formulation. To conclude, it examines the new way the law of nature limits political authority and how Physiocratic despotism is structurally compatible with the liberal understanding of political authority.
Informalidades e reação popular em uma periferia fluminense: O estranho caso do “astrólogo racista”
Authors: MONTEIRO LINDERVAL AUGUSTO
Published: February 2025

RESUMO O artigo diz respeito a uma narrativa intensiva do segundo caso de linchamento ocorrido na Baixada Fluminense (Rio de Janeiro) no período seguinte ao movimento de colonização proletária da região - algo que localizo entre as décadas de 1950 e 1980. Trata-se do linchamento de Felício Batista de Souza, de 41 anos, que foi tocaiado por cinco de seus vizinhos na rua Washington Luís, bairro Nova Canaã, em Nova Iguaçu. O crime foi detalhadamente exposto pelos principais periódicos cariocas nas semanas e meses seguintes ao seu acontecimento (07 de junho de 1970), provavelmente porque era a primeira vez que um crime colocava homens pretos contra um branco considerado racista e que se notabilizava como alguém que continuamente ofendia e agredia, auxiliado por policiais, a população preta do bairro em que vivia. Objetivo na presente pesquisa relacionar o suplício de Felício com as formas populares de colonizar a Baixada, bem como pensar as representações presentes nos periódicos cariocas sobre a região na década de 1970 e as relações entre pretos e brancos numa comunidade invisível até os anos de chumbo da última ditadura militar brasileira.

RESUMO O presente artigo visa problematizar como o passado do Jiu-Jitsu está sendo representado no Instagram a partir da análise mais detida de uma conta em especial. O @muito_antes_do_mma é um perfil dedicado a compartilhar conteúdos sobre os principais pioneiros do Jiu-Jitsu ao redor do mundo. A iniciativa na rede social é feita por dois pesquisadores autônomos, lutadores praticantes e sem formação acadêmica na área da história. Ao realizar um cuidadoso levantamento de dados sobre a presença do Jiu-Jitsu em diferentes países ao redor do mundo, seus autores oferecem ao público um panorama global da inserção desta arte marcial em diferentes espaços, estabelecendo até mesmo conexões entre indivíduos e suas instituições. Entretanto, a forma como as publicações são construídas refletem uma narrativa histórica extremamente tradicional, que exalta o pioneirismo e trajetórias individuais. A ausência de um problema de pesquisa torna o conteúdo superficial e pouco explicativo, priorizando os aspectos informativo e enciclopédico dessa iniciativa.

Abstract The shrub Rubus erythroclados Mart. ex Hook.f. is endemic to Brazil and has high nutritional and medicinal potential. The objective of this study was to test scarification methods in the seed germination of R. erythroclados and to characterize the early stages of seedling development. The seeds were submitted to four treatments: 1) distilled water; 2) sodium hypochlorite (5% NaOCl); 3) sulfuric acid (80% H2SO4) and 4) sulfuric acid (98% H2SO4). The experimental design used was completely randomized. Each treatment (150 seeds) contained three replications with 50 seeds each, totaling 600 seeds. The seedling phase was also monitored weekly, from emergence to the loss of cotyledons. Furthermore, young plants were monitored until they acquired 5-leaflets. Seed germination had a general average of 46.3%. The treatment 5% NaOCl showed the highest mean germination (88.7%), followed by 80% H2SO4 (66.7%), both higher than the distilled water (30.0%). No seeds germinated in the 98% H2SO4 treatment. The seedling emergence time in the substrate was, on average, 54.4 days, ranging from 22.3 to 107.3 days, after sowing. The 5% NaOCl and 80% H2SO4 treatments increased the percentage of seed germination by scarification and reduced the seedling emergence time, being indicated for the cultivation of R. erythroclados. On the other hand, the 98% H2SO4 treatment is not indicated, as it possibly damaged the seeds. In the seedling phase, the growth in height was slow and the average number of leaves increased over the weeks. This phase lasted on average 107.9 ± 14.3 days. Pentafoliate leaves were observed on average 398.5 ± 54.7 days and lateral sprouting on average 435.7 ± 54.7 days, both after seedling emergence. These results indicate that plants produced by seeds may take some years to become sexually reproductive.

Abstract This study aimed to evaluate the effects of Ocimum basilicum supplementation in the diet for Piaractus mesopotamicus regarding productive performance, intestinal morphology, muscle residue, and hematological changes after simulated transport stress. Juvenile (23 g±0.08, n = 180) were stocked into 300-L tanks in three treatments and six replicates each: a control diet (not supplemented), a diet with 0.5% essential oil of O. basilicum and a diet with 0.5% aqueous extract of O. basilicum. After 45 days, weight and length were measured, and the fish were submitted to a 4-hour simulated transport to assess the stress responses and the possible effects of the experimental diets on them. The main components of the essential oil were methyl chavicol (70.81%) and linalool (22.04%), while the aqueous extract contained tannin levels of 262.59±24 mg kg-1. The retention rate of the essential oil was about 50%, while the aqueous extract retention varied between 77 and 82%. The results showed no significant effect of basil on the productive performance of the fish. Fish supplemented with the aqueous extract exhibited a lower intestinal mucosal height compared to other groups. Additionally, transported fish showed increased blood glucose concentrations even higher in fish supplemented with the aqueous extract. It was concluded that supplementation with 0.5% basil, either as essential oil or aqueous extract, did not benefit productive performance, intestinal morphology, or reduce transport stress in pacu.

ABSTRACT: Bovine tuberculosis (TB), caused primarily by Mycobacterium bovis, is a zoonotic infectious disease with significant economic impacts on the milk production chain due to the reduction in zootechnical indices. This study aimed to investigate and describe the epidemiological and pathological characteristics of tuberculosis in a Jersey cattle property in southeastern Rio Grande do Sul, focusing on transmission routes and clinical and histopathological findings. The outbreak, affecting 15% of the herd, suggested potential transmission routes, including human-mediated transmission, facility contamination, wild animal vectors, and undetected infection in founder animals. Both adult and young animals, including calves that were only a few days old, were affected, suggesting aerogenous and congenital transmission, respectively. Pathological examination of the affected calves showed granulomatous lesions, primarily in the respiratory tract, significant necrosis, and abundant acid-fast bacilli. These findings highlight the need for vigilant diagnostic practices and effective management strategies to control bovine tuberculosis, particularly in endemic regions. This study underscores the importance of considering tuberculosis as a differential diagnosis in cases of weight loss and respiratory symptoms in animals, including young animals.
Do policing strategies affect political attitudes? The effects of police stops on satisfaction with democracy in São Paulo
Authors: Teles José , Branco Frederico Castelo
Published: February 2025

The police are among the most visible state representatives. Yet, little is known about how police-citizen contacts affect political attitudes. In Brazil, police stops have been central to public security measures since the late 1990s. These stops often violate citizens’ civil rights. Drawing upon panel data representative of the city of São Paulo, we investigate whether being stopped or being stopped at gunpoint by the police affect citizens’ satisfaction with democracy. To conduct this analysis we apply the panel match model that combines difference-in-differences with matching. We also test a causal mechanism that relates police stops to satisfaction with democracy considering perceptions of police procedural fairness. Our results indicate that police stops at gunpoint reduce satisfaction with democracy because the stops reduce perceptions of procedural fairness.
The Brazilian Amazon and the Soveregnist Discourse: old and new storylines
Authors: Amorim Bruna Eloy de , Peyerl Drielli
Published: February 2025

In this article, we investigated the Brazilian sovereignist discourse about the Amazon, analyzing how it reflects and shapes policies of the Brazilian state for the region. To do this, we used Content Analysis and Discourse Analysis (particularly the Argumentative Approach developed by Maarten Hajer) to examine statements about the Amazon made by Brazilian representatives from 1972 to 2021. This methodological combination allowed identifying the main storylines that contributed to legitimizing the sovereignist discourse, which is grounded in the affirmation that there is a recurring foreign threat to the forest. We conclude that the incorporation of this discourse by different social groups allowed successive governments to prioritize geopolitical and national security interests in the formulation of policies for the region, often at the expense of local socio-environmental problems.
Do voluntarismo político ao populismo jurídico: a gramática da operação Lava Jato nas mídias sociais
Authors: Petrarca Fernanda Rios , Filgueiras Carlos Henrique
Published: February 2025

Este artigo analisa os usos que a operação “Lava Jato” fez das mídias sociais para promover tanto a adesão social ao projeto político-jurídico empreendido pela referida operação, quanto transformar indícios de corrupção em “maior escândalo já visto no país”. O universo empírico que serve de base para essa pesquisa consiste no conjunto de postagens realizadas, através das plataformas digitais, em especial o Facebook, das contas pessoais dos procuradores da “Lava Jato”, com o objetivo de examinar os quadros interpretativos da realidade que ela oferece e como isso se tornou um recurso para promover credibilidade e engajamento público. A análise permitiu evidenciar dois aspectos centrais. De um lado, a retórica populista se apresentou como o princípio mais geral que organizou os enquadramentos produzidos. De outro, o voluntarismo político, como ideologia do Ministério Público, foi o combustível para que o populismo jurídico se tornasse a gramática moral e política da Lava Jato.

A tarefa apresentada, de natureza exploratória, faz parte de uma sequência de tarefas integrada numa experiência de ensino realizada no 3.º ano de escolaridade. Trata-se de um estudo de natureza qualitativa na modalidade de investigação baseada em design. A recolha de dados realizou-se em contexto educativo, através da observação participante, e envolvendo vários instrumentos: gravações vídeo, registos fotográficos, registos escritos dos alunos e notas de campo. A análise de dados é centrada na análise de conteúdo do momento de discussão coletiva da tarefa. São analisadas as resoluções dos alunos relativamente ao processo de medir e as ações do professor e da investigadora, na condução daquele momento. Dos resultados, conclui-se que houve alterações no conhecimento dos alunos, tanto a nível conceptual como processual, embora continuem a existir algumas fragilidades no conhecimento conceptual. Destaca-se a discussão coletiva como momento facilitador dessas alterações, assim como as ações do professor e da investigadora, como contributos para a aprendizagem.
Non-Typical learning sites: A railway platform and an interplay between foreground, uncertainty, and hope

Published: February 2025

Abstract After watching the groups of boys studying at the stairs of a suburban railway station in Mumbai for a while, we decided to talk to those students in order to understand their choice for such an unusual place of study. Adopting an eclectic exploratory approach, this paper argues that such impromptu places of collective learning are often guided by the prospects of inter and intra peer group learning and tend to redefine young students’ foregrounds who handle their financial disadvantaged conditions to come out of their background, empowering themselves and achieving autonomy. This paper hypothesises that this railway platform provides opportunities to those whose performance in formal education remained poor and to those who could not afford the capitalist market of private tuitions (additional academic coaching other than in schools for getting an edge in examinations) thereby missing out on future scope. Despite the gender disparity, such impromptu places of learning also tend to resist the enculturation process of the dominant cultural capital and it also creates an interplay between uncertainties, hopes, and foreground as well.
Pesquisar e formar: construindo conhecimentos com professoras que ensinam Matemática nos anos iniciais do Ensino Fundamental
Authors: Leite Vania Finholdt Angelo , Silva João Alberto da
Published: February 2025

Resumo O objetivo deste artigo é analisar os conhecimentos produzidos em uma pesquisa-formação com 15 participantes que se engajaram em discutir práticas de ensinar e aprender situações multiplicativas nos anos iniciais do Ensino Fundamental na perspectiva de Vergnaud. Para compormos as análises, com base nos estudos de Vergnaud sobre o Campo Conceitual Multiplicativo e na perspectiva de pesquisa-formação de Josso, utilizamos dez registros narrativos das participantes, 15 registros da pesquisadora e transcrições dos 15 encontros ocorridos no primeiro semestre de 2023. Ao finalizarmos os encontros, passamos para a segunda etapa da pesquisa que constituiu na análise das narrativas e dos registros, organizando-os em três dimensões referentes aos seguintes aspectos: a do olhar da pesquisadora, a postura pessoal das participantes, a intersecção entre o olhar de pesquisadora e postura pessoal. A pesquisa evidenciou que o engajamento, a disponibilidade e a confiança em compartilhar as práticas de ensinar situações multiplicativas foi essencial na construção dos conhecimentos. Outro fator foi colocarmos em primeiro plano a dimensão do Ser Mais, por sermos pesquisadoras narradoras que narramos e vivemos a pesquisa. Por fim, o equilíbrio entre os saberes referenciais coletivos do Campo Conceitual Multiplicativo com as demandas, as dúvidas, os pontos de vistas e as construções pessoais de cada um se complementaram na construção de conhecimentos que cada uma realizou nos encontros.
