Authors: DARA PADMAJA , MOPURI RAMADEVI , A. SUJATHARANI
Published: February 2025

Background

Didactic lectures form a large part of the teaching–learning process in medical education. To impart competency-based medical education (CBME) in the Covid-19 pandemic there was a shift to online learning. This pedagogical change would likely impact the efficacy of student learning outcomes. Several studies have shown that learning outcomes and knowledge retention increase considerably when lectures are interactive. However, the efficacy of online teaching with active learning strategies has not been studied.

Methods

At the Department of Biochemistry, Osmania Medical College, Hyderabad, we did this study with 203 first year MBBS students. Five sessions were conducted on the topic of ‘Enzymology’ with appropriate active learning methods. Each lecture session was preceded and followed by a test, which included multiple-choice questions (MCQs) and brief note questions (BNQs). Feedback of students, was recorded on the 5-point Likert scale from strongly agree to strongly disagree.

Results

The majority of students felt that answering questions in the pre-test required substantial effort compared to the post-test. The case scenarios included in the pre-test had a positive impact on the curiosity of students. The activities as part of self-directed learning were interesting, and enhanced understanding and retention. They felt lectures without pre-and post-tests were less efficacious and thus should be continued in all the classes.

Conclusion

Online lectures without pre-and post-test model were less efficacious. Online teaching, coupled with active learning increased interest and the understanding capacity of students.

Малые города России сталкиваются с рядом социально-экономических, демографических, инфраструктурных и других проблем, которые препятствуют устойчивому развитию. Для реализации программы устойчивого развития малых городов России необходимо учитывать природный потенциал таких территорий, составляющий основу экологического каркаса малого города. Цель работы заключается в оценке эколого-хозяйственного баланса локальной территории с учетом антропогенной нагрузки на примере долины реки Вяз в городе Высоковск Московской области. Оценка производится расчетом коэффициентов абсолютной и относительной антропогенной преобразованности, а также естественной защищенности ненарушенных или слабонарушенных ландшафтов. С помощью дистанционного дешифрирования космических снимков определены категории земель, дана оценка их состояния. С помощью геоинформационных методов рассчитано соотношение территории каждой категории земель к общей площади рассматриваемой территории. Построена карта-схема категорий земель и их распределение по территории долины реки Вяз в городе Высоковск. Выделены подкатегории земель долины реки. Как результат, подведены итоги состояния эколого-хозяйственного баланса и экологического фонда территории, выявлены наиболее уязвимые участки и основные рекреационные зоны, рациональное использование которых способно повысить устойчивость территории.

Small towns in Russia face a number of socio-economic, demographic, infrastructural and other problems that hinder sustainable development. To implement the program of sustainable development of small towns in Russia, it is necessary to take into account the natural potential of such territories which forms the basis of the ecological framework of small town. The purpose of the work is to assess the ecological and economic balance of the local territory, taking into account the anthropogenic load, using the example of the Vyaz River valley in the town of Vysokovsk, Moscow Oblast. The assessment is carried out by calculating the coefficients of absolute and relative anthropogenic transformation, as well as the natural protection of undisturbed or slightly intact landscapes. With the help of remote decoding of satellite images, the categories of lands were determined and their condition was assessed. The ratio of the territory of each land category to the total area of the territory under consideration is calculated using geoinformation methods. A schematic map of land categories and their distribution over the territory of the Vyaz River valley in the town of Vysokovsk is constructed. The subcategories of the lands of the Vyaz River valley are highlighted. As a result, the outcomes of the state of the ecological and economic balance and the ecological fund of the territory are summarized, the most vulnerable areas and the main recreational areas are identified, the rational use of which can increase the stability of the territory.

На основе полевых наблюдений в теплый период года (май, июль, сентябрь 2024 г.) проведена оценка параметров углекислотных и световых зависимостей СО2-газообмена листа дуба черешчатого (Quercus robur L.) и лещины (Corylus avellana), произрастающих на двух ключевых участках карбонового полигона «Way Carbon» (Чеченская Республика). В вегетационной динамике более высокие величины параметров световой зависимости выявлены преимущественно у деревьев дуба и лещины равнинной популяции (участок «Черноречье») относительно низкогорной популяции (участок «Рошни-Чу»). В среднем за вегетацию листья дуба и лещины равнинной популяции связывают в 8 раз больше СО2, чем они выделяют в результате темнового дыхания. В низкогорной популяции листья дуба менее экономно расходуют ассимиляты (4:1), поглощая углекислый газ в меньшей степени относительно его выделения при дыхании по сравнению с лещиной (6:1). Вместе с тем выявлена схожая направленность сезонных изменений показателей углекислотной зависимости фотосинтеза для дуба и лещины в разных популяциях. Отмечено влияние этапа онтогенеза листа и водного статуса растения на изменчивость параметров фотосинтеза в течение вегетации. Полученные результаты использованы для расчета потенциальной продуктивности фотосинтеза дуба и лещины в лесных экосистемах Северного Кавказа.

The paper presents the results of assessment of the photosynthetic response to increasing CO2 (A-Ci curve) and light intensity (A-Q curve) in common oak (Quercus robur L.) and common hazel (Corylus avellana) trees growing at two key sites of the Way Carbon landfill (Chechen Republic). Field observations at both sites were conducted in the warm period of the year (May, July and September 2024). During the growing season, higher values of parameters in light response curves were revealed mainly in oak and hazel trees of the plains population (Chernorechye site) relative to the foothills population (Roshni-Chu site). Leaves of oak and hazel of the plains population on average sequester 8 times more CO2 than they release through dark respiration during the growing season. Photosynthetic CO2 uptake of oak in the foothills population exceeded its release by foliage during dark respiration only 4-fold compared to hazel (6-fold). At the same time, photosynthetic parameters obtained from CO2 response curves for oak and hazel in different populations mainly demonstrated a similar response to intraseasonal changes in plant growth conditions. The effect of leaf development stage and plant water status on the variability of photosynthesis parameters during the growing season was noted. The results were used to calculate the potential photosynthetic productivity of oak and hazel in forest ecosystems of the North Caucasus.

В статье произведена оценка влияния высших гармонических составляющих напряжения на работу силовых трансформаторов в системе электроснабжения промышленных предприятий. Протекание токов высших гармоник по обмоткам трансформатора вызывает добавочные потери активной мощности в нем, что может приводить к нарушению теплового режима трансформатора. Оценку влияния высших гармоник на работу трансформатора можно провести путем сравнения потерь активной мощности и далее теплового режима в нем при несинусоидальном и синусоидальном напряжении. Выполнен электромагнитный расчет трансформатора и на основе рассчитанных конструктивных параметров определены зависимости превышения температуры в разных элементах трансформатора для двух указанных выше режимов его работы в функции от коэффициента нагрузки. Из анализа зависимости превышения температуры в обмотке низшего напряжения трансформатора в функции коэффициента загрузки видно, что превышение значения коэффициента нагрузки трансформатора сверх допустимого приводит к превышению температуры обмоток относительно величин, определенных нормативными данными.

The article assesses the influence of higher harmonic components of voltage on the operation of power transformers in the power supply system of industrial enterprises. The flow of higher harmonic currents through the windings of the transformer causes additional losses of active power in it, which can lead to disruption of the thermal conditions of the transformer. The influence of higher harmonics on the operation of a transformer can be assessed by comparing active power losses and then the thermal regime in it at non-sinusoidal and sinusoidal voltages. An electromagnetic calculation of the transformer was performed and, based on the calculated design parameters, the dependences of the temperature rise in different elements of the transformer were determined for the two above-mentioned operating modes as a function of the load factor. From the analysis of the dependence of the temperature rise in the low-voltage winding of the transformer as a function of the load factor, it can be seen that exceeding the transformer load factor value above the permissible value leads to an increase in the temperature of the windings relative to the values determined by the standard data.
Выявление признаков депрессии на основе пользовательских данных из социальных сетей с помощью нейронных сетей
Authors: Солохов Т.Д. , Кочкаров А.А.
Published: February 2025

В статье рассматривается проблема выявления признаков депрессии на основе пользовательских данных из социальных сетей с применением методов машинного обучения и сетевого анализа. Исследование включает разработку модели выявления пользователей с признаками депрессии, которая основана на текстовом анализе их публикаций в социальных сетях, а также метаданных профилей в социальной сети. В качестве алгоритмов в исследовании были использованы нейронные сети, что позволило достичь высокой точности классификации. Графовый анализ, проведенный для анализа влияния пользователей с признаками депрессии, демонстрирует, что такие пользователи имеют низкую степень центральности и не образуют плотных кластеров, что свидетельствует об их социальной изоляции. Гипотеза о распространении депрессии через социальные связи не подтвердилась, что указывает на минимальное влияние депрессивных пользователей на окружающих. Результаты исследования могут быть полезны в целях разработки систем раннего выявления депрессии. Особое внимание уделено ограничениям работы – использованию данных только одной социальной сети и сложности обработки текстовых данных. В статье предложены перспективы дальнейших исследований, направленные на расширение методов анализа распространения депрессивного поведения в социальных сетях.

The article studies the problem of identifying signs of depression based on user data from social networks using machine learning methods and network analysis. The study includes the development of a model for detecting users with signs of depression, which relies on text analysis of their social network posts and profile metadata. Neural networks were used as algorithms in the study, showing high classification accuracy. Network analysis was implemented to examine the influence of users with signs of depression and it shows that such users have low centrality and do not form dense clusters, indicating their social isolation. The hypothesis of depression spreading through social connections was not confirmed, suggesting minimal impact of depressive users on others. The research results can be utilized to develop systems for early detection of depression. Special attention is given to the study's limitations, including the use of data from a single social network and the complexity of processing textual data. The article proposes directions for further research aimed at expanding methods for analyzing the spread of depressive behavior in social networks.

Published: February 2025

В статье впервые в сравнительном аспекте рассматриваются заговорные тексты (монг.: шившлэгийн үг, калм.: шимлдл, бурят.: шэбшэлгэ — нашептывание), используемые монгольскими народами в лечебной практике. Анализу подвергаются материалы, собранные в Республике Бурятия, Республике Калмыкия и Монголии (МНР) в 2023 г. в рамках проекта «Фольклор монгольских народов — источник эмпирических знаний о здоровье человека и традиционно-медицинской практике». Наряду с традиционными лечебными практиками, основное внимание уделяется вербальному компоненту народной медицины. Рассмотрены заговорные тексты общего характера и от конкретных болезней. Отмечается, что в текстах заговоров нашли отражение народные знания о здоровье человека, способах лечения, причинах возникновения болезни. В ходе анализа выявлена единая семантическая основа заговорных конструкций монгольских народов. Установлено, что в магических ритуалах и в заговорных текстах содержатся малоизвестные сведения и практические предписания охранительного характера, они нацелены на обеспечение безопасности и устранение зловредных для жизни человека явлений. Определено, что мотивацией ритуальных действий по заговариванию болезней является просьба об уходе мифологического духа болезни. Полевые материалы подтверждают, что заговоры, обереги и другие компоненты магических ритуалов и обрядов использовались довольно эффективно на протяжении многих веков и не потеряли значимости в наши дни, а предостережения и запреты, представленные в фольклоре и обычаях монгольских народов в разных формах, помогали людям бережно относиться к здоровью.

This article is the first to compare the spells (zagovory) used by Mongolian peoples for healing. Analyzed are materials collected in the Republic of Buryatia, the Republic of Kalmykia and Mongolia (MPR) in 2023 as part of the project “Folklore of the Mongolian Peoples — A Source of Empirical Knowledge About Human Health and Traditional Medical Practice.” Along with traditional healing practices, the article analyzes the verbal component of traditional medicine. It examines both short and detailed incantations, both of a general nature and those concerning specific diseases. Incantations reflect folk knowledge about human health, the causes of diseases and methods of treatment. During analysis of the verbal material the rituals and spell texts contain information and practical instructions for disease prevention that are aimed at ensuring people’s safety and eliminating phenomena that are harmful to human life. The motivation for these ritual acts is to request that the mythological spirit of the disease depart. Field materials confirm that incantations, amulets and other components of magical rituals have been used for many centuries and have not lost their significance today, and that the warnings and prohibitions presented in the folklore and customs of the Mongolian peoples in various forms have helped people take care of their health.
Violence in Algerian Society and its Eradication between Reality and Challenge: The Case of Algerian School
Authors: Sahel Malika , Mokrane Fadila
Published: February 2025

Violence in Algerian society remains a serious social evil and a difficult reality that has attracted the attention of scholars, academicians and researchers from different Algerian towns. The focus of different  initial studies performed, mainly focused on the responsibility of the most important institutions concerned with the social  up growing and education, namely the family and the school towards the birth of violence and its eradication. Indeed, in the case one of these crucial institutions fails to perform its duties and assume its responsibility, violence becomes the language of the family with its members, of the school with all its different components; consequently the language of a whole society. On this basis, important questions impose themselves: what is the reality of violence in Algerian schools? And what are the appropriate measures that Algerians should take to reduce or eradicate it? Our analysis resulted in the necessity to review the duties of both the Algerian family and school, and some suggested strategies to reduce or eradicate school violence in the Algerian society.

Published: February 2025

We report a photoredox-catalyzed pseudo-four-component process for the alkylative amidination of styrenes using isocya-nides and redox-active esters (RAEs). This redox-neutral radical-polar crossover reaction shows broad functional group tol-erance. The RAE serves as both a radical and nucleophile source, with the initially released phthalimide anion reintegrated into the final product. The resulting amidines can be readily derivatized into amides, tetrazoles, nitriles, or aldehydes, en-hancing the synthetic utility of this approach.
Penerjemahan Metafora dalam Pidato Politik Presiden Joko Widodo
Authors: Muttaqin Nurul , Jaya Doni
Published: February 2025

Penerjemahan metafora di dalam pidato politik cukup menantang dilakukan karena selain pesan, efek metaforis juga harus dialihkan dengan baik agar terjemahan pidato itu menarik perhatian hadirin. Penelitian ini membahas penerjemahan metafora dalam dua pidato yang disampaikan oleh Presiden Joko Widodo pada sidang Tahunan MPR RI, yaitu pada 16 Agustus 2021 dan 16 Agustus 2023. Penelitian kualitatif ini menganalisis data dengan menggunakan teori prosedur penerjemahan metafora (Newmark, 1980; Larson, 1998; Baker, 2018) dan spektrum ideologi (Jaya, 2018; Jaya, 2020). Data berupa dua buah pidato beserta terjemahannya yang diambil dari situs Sekretariat Kabinet RI. Terdapat delapan bentuk metafora dan 95 kasus penerjemahan metafora. Berbagai metafora itu diterjemahkan dengan empat prosedur penerjemahan metafora. Prosedur yang paling banyak diterapkan adalah metafora bercitra sama (n=60, 63,15%). Temuan lainnya adalah bahwa sebagian besar kasus penerapan prosedur penerjemahan berada pada posisi ideologi medial (n=48, 50,52%). Akan tetapi, ada kecenderungan bahwa penerjemah menerapkan domestikasi meskipun jumlah kasusnya relatif lebih sedikit (n=35, 36,84%). Hasil analisis menunjukkan bahwa penerjemah cenderung menerjemahkan secara setia dan berhati-hati, terutama untuk citra yang mengandung unsur politis. Penerjemah juga terlihat tidak melakukan intervensi yang berlebihan untuk meningkatkan kealamiahan teks sasaran karena citra-citra itu pada dasarnya dianggap telah dapat dipahami.
Tinjauan Komprehensif Social Actor Network oleh Van Leeuwen (1996): Analisis Eksklusi dan Inklusi
Authors: Ernanda
Published: February 2025

Makalah ini menjelaskan representasi linguistik aktor sosial dalam wacana seperti yang dipaparkan dalam Social Actor Network karya Van Leeuwen (1996), dengan menganalisis bagaimana individu dan kelompok dibentuk melalui bahasa. Tinjauan ini mengeksplorasi berbagai strategi—seperti nominasi, spesifikasi, dan generalisasi—serta perannya dalam merepresentasikan aktor sosial dalam bentuk spesifik maupun umum. Tinjauan ini menyoroti bagaimana aktor digambarkan baik sebagai individu yang unik maupun sebagai bagian dari kolektif yang lebih luas, dengan menekankan peran bahasa dalam membentuk identitas sosial. Selain itu, tinjauan ini membahas bagaimana aktor sosial digambarkan melalui proses abstraksi, impersonalisasi, dan objektivasi, yang dapat mengurangi atau menonjolkan kualitas kemanusiaan mereka. Dengan menganalisis strategi linguistik ini, Van Leeuwen menekankan cara-cara kompleks di mana bahasa memengaruhi persepsi sosial, memperkuat dinamika kekuasaan, dan membentuk peran sosial. Representasi aktor sosial tidak bersifat netral, melainkan dibentuk oleh interaksi antara pilihan linguistik dan konteks sosial. Agar tinjauan kritis ini dapat dipahami secara lebih luas oleh pembaca dan diaplikasikan dalam penelitian Analisis Wacana Kritis, maka contoh-contoh disajikan dalam bahasa Indonesia.

Authors: Mala Krishtika , Baker Michael , Stanley James , Bennett Julie
Published: February 2025

aim: To describe the epidemiology of Staphylococcus aureus (S. aureus) and Streptococcal pyogenes (S. pyogenes) skin infections in Auckland, New Zealand.
method: A population-based retrospective analysis of skin swab culture results (2010–2020), collected in primary care, was conducted to determine incidence rates and rate ratios (RR) with 95% confidence intervals (CI), using 2013 New Zealand Census data as the denominator.
results: Over one-quarter of Auckland’s population were tested for suspected skin infections over the 11-year observation period, at 31.4 persons per 1,000 person-years. S. aureus affected all demographics. S. pyogenes infection rates were higher for children under 10 years of age (RR 3.1, 95% CI 3.1–3.2; compared with ≥10-year-olds), Māori and Pacific peoples (RR 4.7, 95% CI 4.6–4.8; compared with European/Other) and individuals in the most socio-economically deprived areas (RR 2.1, 95% CI 1.9–2.3; compared with least deprived areas). Individuals who were S. aureus-positive were twice (2.1, 95% CI 1.9–2.3) as likely to test S. pyogenes-positive, relative to those testing negative for S. aureus or positive for another skin pathogen.
conclusion: Children, Māori, Pacific peoples and people in lower socio-economic areas are more likely to have a skin infection test positive for S. pyogenes. S. aureus infection is a risk factor for co-infection with S. pyogenes.

Published: February 2025

The global trend is mass employment of the population in the informal sector of the economy. At the same time, only in economically developed countries of the world such workers have relatively good working conditions. At the current stage of development, Russia is among the group of actively economically developing countries of the world. Therefore, the improvement of the mechanism of state social protection of those employed in the informal sector of the economy remains an urgent relevant issue for our country, which, in turn, implies monitoring of the situation.

The purpose of this study is to develop tools for such monitoring with the help of artificial intelligence (more precisely, modern machine learning methods). According to the results of cluster analysis carried out using the k-means method in the Python programming language, it was found that in modern Russia there is a high degree of differentiation of regions by the level of employment in the informal sector of the economy. At the same time, most of the subjects of the Russian Federation are characterised by the same situation as in economically developing countries of Eastern Europe (Bosnia and Herzegovina, Serbia, Czech Republic). Four regions of Russia (from the North Caucasus Federal District) have an abnormally high level of employment in the informal sector of the economy comparable only with economically developing countries of Asia, Africa, North and South America. In the course of solving the classification problem using a modern machine learning method (LightGBM), the key factors affecting the level of employment in the informal sector of the economy of Russian regions were identified.

According to the classification results, we can conclude that a cardinal change in the current situation is not expected in the future. Therefore, for modern Russia, it is necessary to improve the state social policy for a significant part of the regions.

The results of the empirical study can be applied to improve the effectiveness of the state social policy of the Russian Federation. Thus, in particular, it will be possible to specify the amount of financial resources required for additional social support of the employed population of certain regions of our country.
The Use of Artificial Intelligence Technologies in Energy and Climate Security
Authors: Guliev I. A. , Mammadov A. , Ibrahimli K.
Published: February 2025

This study provides a theoretical analysis of the use and application of artificial intelligence (AI) in the energy sector as it relates to climate security.

The object of the study is energy and climate security as types of economic activity and social activity.

The subject of the research is artificial intelligence in relation to the object area of  research.

The purpose of the study is to create a sound scientific basis for the use of artificial intelligence in the energy sector, as well as to identify emerging problems in the formation of a science-based approach to climate policy development.

The authors’ research includes three interrelated research methodologies: topic modeling, text mining as part of qualitative analysis and object modeling as part of the systematization of results that are adequate to the subject area of  the study and correspond to their reality; in addition, the authors supplemented the quantitative results with a theoretical and heuristic analysis of the scientific results of other researchers. The concept of parametric optimization (PO) is used as an effective method for solving the applied problem of testing the hypothesis of managing energy costs and energy efficiency based on AI in order to achieve optimal performance of the technical system and compliance with the Sustainable Development Goals (SDGs) in the field of climate security.

The study’s findings suggest that AI is becoming fundamental to the development of a modern energy sector based on data and complex relationships and provides tools to improve technical system performance and efficiency in the face of sanctions restrictions.

The authors conclude that the truth of the hypothesis has been proven: the use of AI as a control feedback loop at a technical facility for purification and energy generation is a more cost-effective and technically optimal alternative to a “live” operator, which will eliminate the human error factor. In this regard, the energy industry, utilities, grid operators and independent power producers must pay special attention to the introduction of AI technologies into existing technical systems.

Two new copper(II) complexes, [CuBrL] (1) and [CuL(CH3COO)] (2), where L is the deprotonated form of the Schiff base 5-bromo-2-((2-diethylaminoethylimino)methyl)phenol (HL), have been prepared. The Schiff base and complexes were characterized by IR and UV spectra. In addition, the free Schiff base was characterized by 1H NMR spectrum. Structures of the complexes were further confirmed by single crystal X-ray determination. The Cu atoms in the complexes are in square planar coordination. The Schiff base ligand coordinates to the Cu atoms through phenolate oxygen, imino nitrogen and amino nitrogen. The bromide and acetate anions in the complexes furnish the square planar coordination. Catalytic property for epoxidation of styrene by the complexes was studied.

Este artigo se enquadra como um relato de experiência acerca do projeto de pesquisa intitulado “Comunidades Tradicionais, Políticas Públicas e Desenvolvimento Territorial: Povos Indígenas e Quilombolas em Alagoas”, que recebe o apoio institucional da Fundação de Amparo à Pesquisa do Estado de Alagoas, no âmbito do Edital nº 03/2022 - Apoio a Pesquisas Humanidades. O projeto tem como objetivo realizar o diagnóstico das condições estruturais, políticas e pedagógicas de um conjunto de 10 escolas (cinco indígenas e cinco quilombolas) presentes em distintos contextos territoriais do estado de Alagoas. Já a proposta deste texto preliminar é apresentar o relato de experiência de duas visitas técnicas realizadas em escolas das Terras Indígenas Tingui Botó e Xukuru-Kariri, a fim de elaborar uma caracterização estrutural e traçar uma análise crítica das políticas públicas educacionais implementadas nesses espaços escolares. Com base no materialismo histérico dialético, foram aplicados como procedimentos metodológicos a revisão bibliográfica sobre o tema e a pesquisa empírica qualitativa mediante o trabalho de campo e a aplicação de questionários e entrevistas semi-estruturadas. Por fim, o artigo proposto aponta questões desafiadoras sobre a Educação Escolar Indígena, em particular, e no tocante às políticas públicas direcionadas para os povos tradicionais do Brasil, em geral.

O presente trabalho teve como objetivo analisar a vulnerabilidade da paisagem à perda de solo da Bacia Hidrográfica do Igarapé da Agrovila Tefé-Amazonas, procurando compreender como os processos de uso da terra influenciam nas transformações na paisagem e em seus graus de vulnerabilidade. Utilizou-se a metodologia proposta por Crepani et al. (2008), adaptada para o presente estudo, essa metodologia é baseada nos princípios da Ecodinâmica proposta por Tricart (1977), em que busca-se estabelecer por meio da inter-relação de variáveis as áreas com diferentes graus de vulnerabilidade. Para se alcançar a síntese das variáveis analisadas utilizou-se o método AHP (Analytic Hierarchy Process) para a hierarquização das variáveis, onde os pesos foram atribuídos a cada variável. Desta forma, foram analisadas as seguintes variáveis: Uso da Terra e Cobertura Vegetal, Declividade do terreno, Solo, Geologia e Erosividade das Chuvas, e realizada a identificação com base no grau de vulnerabilidade de cada variável classificadas como Muito Baixa, Baixa, Moderada, Alta e Muito Alta. Os resultados demonstraram que a Bacia Hidrográfica do Igarapé da Agrovila Tefé-AM apresenta 56,09%, correspondendo ao grau de vulnerabilidade baixa e 42,04% para o grau de vulnerabilidade moderada. Conclui-se que seguindo esse modelo, facilita a localização e diagnóstico de áreas que se encontram vulneráveis à desencadear possíveis impactos negativos na Bacia Hidrográfica.

O sul do Amazonas passa por transformações espaciais, se configurando como fronteira agrícola, processo facilitado pelos eixos de circulação implementados durante o governo militar. Essa pesquisa buscou sistematizar o processo histórico do avanço da nova fronteira agrícola espacial nos assentamentos no sul do Amazonas, bem como analisar os principais processos que impactaram o ambiente que estão inseridos. Para tal, foram realizados trabalhos de campo entre dezembro de 2017 e novembro de 2023 para observação exploratória e entrevistas com as famílias. Para identificar as áreas que apresentam impactos nos assentamentos, o estudo utilizou dados cartográficos secundários. Esses dados englobaram os municípios de Boca do Acre, Lábrea, Canutama, Humaitá, Manicoré, Novo Aripuanã e Apuí, localizados no sul do Estado do Amazonas. Conclui-se que esse processo de expansão da fronteira é constantemente impulsionado pelas rodovias BR-230 e BR-319, assim como pelos governos que incentivaram a expansão fundiária, a implementação e o crescimento do agronegócio em áreas públicas destinadas à reforma agrária, ou seja, em áreas institucionalizadas pelo Estado brasileiro.

Published: February 2025

Este texto tem como objetivo apresentar Estrabão e discutir seus estudos geográficos tendo como preocupação o fato necessário de conhecermos a gênese da Geografia para melhor atuarmos nesta ciência contemporaneamente. Resulta de estudos sobre o autor e sua obra e da importância que ele tem para o desenvolvimento do conhecimento histórico geográfico. Trabalhamos com a metodologia histórica, utilizando o método histórico e lógico, constituído de procedimentos e técnicas utilizados para revelar os fatos do passado e construir a historiografia de um período determinado partindo das fontes escritas. A Geografia como conhecimento necessário ao desenvolvimento da humanidade tem uma longa história. Ao longo do tempo, numerosos foram os pensadores que deram atenção especial ao estudo da gênese do conhecimento geográfico, dentre eles, Estrabão, grego culto que nasceu em 63 a.C. em Amasia atual Turquia. Estrabão figura como essencial pelo legado deixado em sua obra “Geografia”. Esta é um compendio da herança geográfica de suas viagens pelo mundo conhecido de sua época, o oikoumene, na qual relaciona o homem com o meio. Testemunho de uma época em transformação, de hegemonia romana que conquistava novos territórios, esse geógrafo ampliou os horizontes geográficos e contribuiu para o desenvolvimento do que se definiu como Geografia.
LOS ALMANAQUES DEL BANCO DE SEGUROS DEL ESTADO (1914-2023) COMO FUENTE DOCUMENTAL PARA EL ANÁLISIS DE LAS CONCEPCIONES ACERCA DEL RIESGO AMBIENTAL
Authors: Bruschi Rita
Published: February 2025

Este trabajo pretende hacer un primer abordaje de una investigación en curso, planteando la discusión de los Almanaques del Banco de Seguros del Estado como fuente documental para la identificación de las distintas manifestaciones acerca del riesgo ambiental, buscando vincularlas con distintos enfoques epistemológicos sobre el ambiente. El Banco de Seguros del Estado, en forma prácticamente ininterrumpida desde 1914 hasta el presente, ha impreso y distribuido anualmente en forma gratuita para sus clientes, una serie de almanaques con una amplia difusión a nivel rural y urbano, que han sido muy valorados por la población uruguaya. Las temáticas ambientales y, en particular el riesgo ambiental, han estado presentes desde la razón de la existencia de estos almanaques, que han buscado promover fundamentalmente en el campo, pero también en la ciudad, la conciencia de la necesidad de contar con seguros frente a las adversidades. Su larga historia y arraigue popular permite, además, aproximarnos al pensamiento y la forma de vivir en distintos momentos históricos del Uruguay moderno.

Published: February 2025

Nessa produção textual, apresentamos os resultados iniciais de uma pesquisa de mestrado em andamento sobre as escolas ribeirinhas de Manaus, tendo a Escola Municipal José Sobreira do Nascimento, na Comunidade Nossa Senhora de Fátima, como estudo de caso até o momento. Nosso objetivo é contextualizar o acesso ao ensino fundamental nessas instituições no município e verificar como o tempo ecológico/cíclico interfere na escola da comunidade. Para isso, realizamos mapeamentos para mostrar onde estão e como estão distribuídos os elementos que modificam o cotidiano dos estudantes, tais como a localização das escolas, a proximidade com o rio, as estradas e a área urbana de Manaus. Os gráficos, por sua vez, mostraram a dinâmica do êxodo rural no município e a taxa de abandono na Escola Municipal José Sobreira do Nascimento. A partir desses dados, é possível relacionar as escalas municipal e comunitária não só no mapa, mas na compreensão do funcionamento do ensino fundamental, bem como traçar aproximações e distanciamentos com outras realidades, identificando particularidades dentro do processo geral de escolarização. Dessa forma, foi possível elencar algumas condições espaços-temporais específicas do lugar na escala municipal e comunitária que atravessam os cotidianos dos estudantes, interferindo na ação corriqueira de ir à escola.

O objetivo deste trabalho foi avaliar a estrutura da paisagem, nos anos de 2000 e 2022, no entorno do Parque Estadual da Serra de Jaraguá (PESJ), unidade de conservação localizada no estado de Goiás. Utilizando uma metodologia que envolveu a análise de dados espaciais em um sistema de informações geográficas, foi gerado um buffer de 10 km no entorno do PESJ e identificadas as classes de uso e cobertura do solo presentes neste. As classes foram quantificadas e agrupadas em três categorias (cerrado, antrópico e corpos d’água), sendo realizada ainda uma análise dos fragmentos de cerrado. Os resultados mostraram, para ambos os anos, que a maior parte da área é ocupada pela categoria antrópica, sobretudo pastagem, a qual constitui uma parcela quase contínua em todos os espaços da área de estudo. Foi identificado um acréscimo na área ocupada pelo cerrado, em cerca de 4%. Nos dois anos analisados, esta classe se concentrava majoritariamente nos espaços situados do extremo leste ao extremo norte da área de estudo. Foi observada a redução da quantidade de grandes fragmentos e aumento da participação de pequenos fragmentos de cerrado. A classe água, mesmo pouco abundante e com distribuição difusa ao longo do buffer, passou por uma redução de aproximadamente 15% no intervalo de tempo analisado. Estes dados evidenciam um panorama preocupante, o qual pode impactar negativamente na manutenção dos processos ecológicos essenciais e no estabelecimento de um ambiente saudável às espécies que dele dependem.
