Recent studies have reported long-range charge transport in peptide- and protein-based fibers and wires, rendering this class of materials as promising charge-conducting interfaces between biological systems and electronic devices. In the complex molecular environment of biomolecular building blocks, however, it is unclear which chemical and structural dynamic features support electronic conductivity. Here, we investigate the role of finite temperature fluctuations on the electronic structure and its implications for conductivity in a peptide-based fiber material composed of an antiparallel coiled coil hexamer, ACC-Hex, building block. All-atom classical molecular dynamics (MD) and first-principles density functional theory (DFT) are combined with interpretable machine learning (ML) to understand the relationship between physical and electronic structure of the peptide dimer subunit of ACC-Hex. For 1,101 unique MD ``snapshots" of the ACC peptide dimer, hybrid DFT calculations predict a significant variation of near-gap orbital energies among snapshots, with an increase in the predicted number of nearly degenerate states near the highest occupied molecular orbital (HOMO), which suggests improved conductivity. Interpretable ML is then used to investigate which nuclear conformations increase number of nearly-degenerate states. We find that molecular conformation descriptors of inter-phenylalanine distance and orientation are, as expected, highly correlated with increased state density near the HOMO. Unexpectedly, we also find that descriptors of tightly coiled peptide backbones, as well as those describing the change in the electrostatic environment around the peptide dimer, are important for predicting the number of hole-accessible states near the HOMO. Our study illustrates the utility of interpretable ML as a tool for understanding complex trends in large-scale \textit{ab initio} simulations.

Metal-functionalized cavitands are promising platforms for mimicking the chemical environments of hydrophobic pockets in natural metalloenzymes. However, successfully combining the unique supramolecular capabilities of cavitand scaffolds, with the high reactivity of transition metal complexes, still remains a major challenge. In this study, we present a conceptually novel cavitand architecture featuring a coordinatively-unsaturated Mn(II) center embedded deep within its pore. This metallocavitand was employed to generate a Mn(IV)-oxo species inside a molecular cavity. This elusive intermediate was fully characterized spectroscopically (UV-vis, EPR, and HRMS) and – for the first time for a pseudo-octahedral Mn(IV)-oxo species – also by XRD. The experimental data was corroborated by detailed ab-initio/TDDFT calculations, confirming the Mn(IV)-oxo (rather than Mn(III)-oxyl) electronic character of this species. Reactivity and mechanistic studies, including monitoring the decay of this complex in various chlorinated solvents and its reactions with representative substrates, revealed that despite the steric protection provided by the cavitand scaffold, its Mn(IV)-oxo core remains highly reactive in both H atom abstraction (HAA) and O atom transfer (OAT) reactions. Moreover, this reactivity is subject to a high degree of steric control imposed by the cavitand framework capable of discriminating between potential substrate molecules based on their size and shape. This was further demonstrated by the regioselective oxidation of a bisphosphine substrate – emulating the regioselectivity of natural metalloenzymes.

Iontronic devices link ion-based transport with established electronic systems. Emerging capacitive devices, like CAPode and G-Cap, feature diode-like rectification and transistor-like switching, respectively, through electrochemical capacitor functionality for enhanced energy storage and signal processing in next-generation low-power electronics. In this study, we present an asymmetric architecture based on nanostructured hexagonal tungsten oxide with significantly enhanced current rectification (with a rectification ratio of 58) providing an efficient ionic transistor with 97.5% switching efficiency under only 1 V bias. Key parameters, such as substrate materials, the mass ratio of counter electrode to working electrode, electrolyte composition and concentration are evaluated to reach the highest rectification ratios.

Published: February 2025

The versatility afforded by emerging additive manufacturing technologies (e.g., 3D printing and precision drop-on-demand deposition) has enabled the rapid and agile production of personalized medicine. The on-demand customization capabilities of these technologies provide novel avenues for point-of-care or distributed pharmaceutical manufacturing and compounding applications. Quality by design principles were used to investigate the production of solid tablet dosage forms for narrow therapeutic index (warfarin), selective serotonin reuptake inhibitor (citalopram), and medical countermeasure (doxycycline) drugs. We examined critical material attributes , critical process parameters, and critical quality attributes for the semisolid extrusion of pharmaceutical tablet excipients and drop-on-demand active pharmaceutical ingredient (API) ink dosing. Detailed investigations optimized the API ink formulation – specifically fluid properties relative to the tablet semisolid excipient, excipient temperature and physical state (i.e., solid vs liquid), and solidification time – allowing for API and excipient mixing and redistribution. Personalized drug dosages, adjusted doses, and tapered regimens were manufactured, demonstrating accurate API quantity and required production content uniformity, as specified by the U.S. Pharmacopeia. Atline API ink verification and inline drop counting control strategies were employed and confirmed by post-production quantification measurements to properly maintain tablet-to-tablet quality assurance.

Published: February 2025

1H-benzimidazoline based molecular n-dopant precursors, such as 4-(2,3-Dihydro-1,3-dimethyl-1H-benzimid-azol-2-yl)-N,N-dimethylbenzenamine (N-DMBI-H), enable efficient doping of n-dopable organic semiconductors. Chemical modification of the molecular structure of such compounds proved to be a fundamental tool to tune their properties and doping efficiencies, according to the desired application. Versatile and efficient synthetic strategies, giving access to the widest range of substitution motifs, could help improve the access to known derivatives and enable the preparation of new and improved ones. Literature reports several syn-thetic approaches but due to lack of rationalization and a comprehen-sive analysis, the selection of that best suited for a specific target deriv-ative still mostly relies on a trial and error approach. In this work, we compare the features of the two most popular synthetic strategies in the preparation of a wide variety of benzimidazoline dopants having diverse substitution patterns and electronic features. We thus propose guidelines for the selection of the best synthetic approach depending on the characteristics of the target dopant, known as well as original.
Beyond HAT: Harnessing TBADT for photocatalyzed C(sp3)-C(sp3) Bond Formation through Reductive SET
Authors: FAGNONI MAURIZIO , Leone Matteo , Arnaldi Dalila
Published: February 2025

Photocatalysis has become a powerful tool for developing sustainable synthetic methods, with the decatungstate anion (TBADT) playing a pivotal role. TBADT facilitates a variety of chemical transformations under mild conditions, primarily through hydrogen atom transfer (HAT) and marginally through single electron transfer (SET) mechanisms. This study explores the dual ability of TBADT to cleave C-H bonds and initiate SET processes, leading to efficient C(sp3)-C(sp3) coupling reactions. We address the main limitations of direct HAT by leveraging the (bi)reduced form of TBADT [W10O32]6− to activate redox-active esters (RAEs), enabling the formation of alkyl radicals for Giese-type additions. An extensive screening of various hydrogen donors showed their pivotal role in the selective generation of the reduced form of TBADT and in suppressing any undesired C-H activation. Our optimized conditions, using γ-terpinene as the hydrogen donor, achieved high yields in alkylations of various olefins, demonstrating the versatility and robustness of the proposed strategy. This methodology extends the application of TBADT in sustainable organic synthesis and in late-stage functionalization of complex molecules for the synthesis of pharmaceutical building blocks

Published: February 2025

This research aims to reveal the richness of ecological metaphors in the natoni oral tradition as a local wisdom of the Atoin Meto culture in West Timor, understand the relationship between language and the environment in the Atoin Meto culture, form support for the preservation of Atoin Meto culture and language, namely the Dawan language, contribute to the field of language ecology, and increase awareness about the importance of environmental conservation.  This study uses a qualitative ecolinguistic approach to analyze ecological metaphors in the natoni oral tradition of the Atoin Meto culture. Data comes from ten YouTube videos of natoni performances, supplemented by interviews. The metaphors were identified, classified, and analyzed to reflect the community's ecological worldview. The study shows that the lexicons in natoni contain ecological lexicons, including flora, fauna, and natural landscape. These lexicons are metaphorical languages that appear in parallelism which depict the social life of the Atoin Meto. Additionally, these lexicons indicate a close relationship with the Atoin Meto community, nature, and God. This research remains open for further study on other aspects of the ecological lexicon in natoni.
Subdialect Classification of Manggarai Language Using Dialectometry Calculation and Gabmap
Authors: Salahuddin
Published: February 2025

Verheijen (1967) noted that there are 43 sub-dialects of the Manggarai language, which are grouped into five dialect groups: West Manggarai, West-Central Manggarai, Central Manggarai, East Manggarai, and Far East Manggarai. However, the Language Development and Fostering Agency states that the Manggarai language has five dialects, including the Tangge dialect in West Manggarai Regency. Neither study was accompanied by scientific evidence underlying the sub-dialect grouping. Therefore, this research aims to provide quantitative evidence to re-evaluate the variations of the Manggarai language, especially those spoken in West Manggarai Regency. Data was obtained by asking 200 Swadesh vocabularies in ten sample observation areas. The results show that the Manggarai language in West Manggarai Regency is divided into three sub-dialect variations, namely the Kempo sub-dialect (MSdK), the Kolang sub-dialect (MSdS>H), and the Transition area sub-dialect (MSdT). Consistent grouping based on dialectometric calculations and cluster analysis proves that MSdK includes Mbuit, Watu Wangka, Sano Nggoang, Siru, and Benteng Dewa. On the other hand, MSdS>H only consists of Golo Lajang Barat because it shows high linguistic differences from other nearby areas. The MSdT includes Watu Waja, Poco Rutang, Lale, and Tentang. Still, the inclusion of Watu Waja in this group needs to be reconsidered because of the differences in results between dialectometric calculations and cluster analysis.

Published: February 2025

The phosphate state of long-term seasonally frozen ordinary chernozem of Western Siberia and frozen ordinary chernozem of Central Yakutia was studied using a complex of soil methods, such as comparative geographical, comparative analytical and profile genetic in combination with standard analytical techniques. It was shown that, despite the similarity of the morphological structure and properties of these soils, their phosphate state differed significantly. Thus, with a generally similar content of total phosphorus, amounting to 67.5-110.1 in the chernozem of Western Siberia, and 98.0–167.3 mg P2O5/100 g of soil in the chernozem of Yakutia, the proportion of organophosphates in the first soil was lower than in the second. Thus, in the chernozem of Western Siberia, phosphates of organic compounds amounted to 44.6-91.4 mg P2O5/100 g of soil, or relatively 66.1- 83,0 % of the total amount of phosphates, while in the chernozem of Central Yakutia, respectively – 68.4-123.7 or 65.8-73.9 %. The studied chernozems of Western Siberia and Central Yakutia also differed significantly in both the total amount and the relative content of individual fractions of mineral phosphates. The latter was especially evident for the iron phosphates and occluded aluminumiron phosphates fractions, the average contents of which in these soils differed by 21 and 5 times, respectively. During mathematical processing of the obtained data using the nonparametric Wilcoxon test, it was found that the content of all studied forms and fractions of phosphates in the studied chernozems differed statistically significantly with a confidence level of p=0,95 and p=0,99. It is assumed that the higher content of iron phosphates and occluded aluminum-iron phosphates fractions in the frozen chernozem of Central Yakutia compared to those noted in the frozen chernozem of Western Siberia is associated with the influence of the cryogenic ferruginization process.

Published: February 2025

The development of cognitive processes in modern adolescents is an urgent problem of psychology and the modern education system, because most teenagers do not develop, and even lose, their intellectual and creative abilities in traditional school, while there is a growing need for highly developed professionals who would creatively address complex and unexpected problems. The aim of the research was to study the peculiarities of thinking and memory of teenagers engaged in scientific and technical creative work in comparison with their peers who are not. The development of cognitive processes of modern teenagers is an urgent problem of psychology and the system of general secondary education, because most teenagers do not develop, and even lose their intellectual and creative abilities in a traditional school, at the time when the need for highly educated professionals who creatively solve complex,unexpected problems is growing. The purpose of the study was to study the peculiarities of thinking and memory of teenagers who are engaged in scientific and technical creative process in comparison with their peers who are not engaged in it. The research was conducted on the basis of the communal institution "Bezlyudivskyi Law Lyceum named after I. Ya. Pidkopai of the Bezlyudivsk Settlement Council" of the Kharkiv region. A total of 66 students aged 10 to 13 took part in the study, of which 30 are additionally engaged in scientific and technical creativity in clubs ("Robotics", "Modeling", "Young researchers", "Step to science"), and 36 - are not engaged in any types of creativity. It has been established that adolescents who are involved in the processes of modeling, construction, invention have higher abilities for systematized, planned, methodical intellectual activity compared to those adolescents who are not involved in this process. It was determined that memory and thinking are correlated among teenagers who are engaged in STC, which suggests the integration of the development of these processes in the course of creative activity. It was found that memory for numbers, memory for texts and operational memory are developed in those who are engaged in scientific and technical activities. They also have better developed logical thinking, the ability to systematize and plan, and general intelligence. In addition, teenagers engaged in scientific and technical activities are distinguished by close relationships between memory and thinking.

Published: February 2025

The article examines the life and professional situation in which early intervention specialists found themselves at the beginning of the war in Ukraine, their needs and features of providing early intervention services to families during wartime. A model of participatory interaction between specialists and the family in early intervention was also built, on the basis of which the checklist "Implementation of early intervention family plan: meeting with the family" was created. Questionnaire and modeling methods were used. Specialists from Kharkiv, Zakarpattia, Odesa, Lviv, Donetsk, Luhansk regions and Vinnytsia were involved (N=76). 52.6% of the surveyed specialists were forced to change their place of residence after leaving the territory of active hostilities. Among those who left, 17.1% of specialists were abroad. 81.6% of specialists continued to work, of which 74.19% - provided RV service, despite the war and forced resettlement. The results of the questionnaire became the basis for creating a model of participatory interaction and its operationalization in the form of a checklist, which consists of five sections that reflect the sequence of actions of specialists: transdisciplinary team, preparation for a meeting with the family, greetings, implementation of goals and support of parents, summarizing and planning the next meeting .The developed checklist is based on evidence-based practices of early intervention and allows to ensure the measurability of participative interaction, which ensures the quality of meetings during the implementation of the family plan of early intervention and their compliance with recommended practices. In the conclusions, the structure of the needs of emergency personnel during the war in Ukraine was determined: obtaining new knowledge about accompanying families and children during the war, knowledge about trauma and work with it, communication with colleagues, financial and material needs, the need for emotional support to prevent emotional burnout; the checklist "Implementation of early intervention family plan: meeting with the family" was substantiated and developed, which allows operationalizing the concept of participatory interaction in early intervention.
Psychological Safety as A Mediator in the Relationship Between Leadership Style and Professional Well-Being
Authors: Voitenko Olena
Published: February 2025

The disclosure of non-linear relationships between leadership characteristics and the professional well-being of employees contributes to the understanding of psychological determinants of this phenomenon and opens perspectives for effective prevention of its violations. The purpose of this study is to test empirically the mediating role of psychological safety in the relationship between leadership characteristics and occupational well-being of employees. To implement the purpose of this study, a cross-sectional method was applied using the Scale of Perceived Leadership of Multifactor Leadership Questionnaire (MLQ, 5X-Short form) Bass and Avolio, Porter's Need Satisfaction Questionnaire (NSQ), Spector's Job Satisfaction Scale (JSS), Scale of psychological safety of Edmondson. The participants of the study were 170 teachers at higher schools of Ukraine. Mathematical and statistical analysis included mediation analysis, correlation analysis. According to the results of the study, it was established that the connection between psychological safety and the professional well-being of employees function through the satisfaction of their psychological needs. Empirical research also confirmed the mediating role of psychological safety in the relationship between leadership style and professional well-being. It was established that the relative contribution of psychological safety in predicting professional well-being increases with a decrease in the positive nature of leadership. Thus, psychological safety moderates the impact of negative leadership characteristics on employee well-being by compensating for the frustration of certain psychological needs. The mediating effects identified by us complement the existing knowledge about the psychological mechanisms of the professional well-being formation in employees and open new perspectives for increasing its level and effective prevention of violations.

Published: February 2025

The purpose of our work was to determine the characteristics of the relationship between professional self-efficacy and subjective success in managers of different levels who work in Ukrainian companies during the war in Ukraine. Managers of different levels (N=58) participated in the study, who were involved in the study through various online platforms. Among the subjects - 43 men and 15 women aged 27 to 56 years. Research methods: questionnaire, numerical scaling, questionnaire of professional self-efficacy ("Short occupational self-efficacy scale"), "Who am I?" method. M. Kuhn and T. McPartland. The managers under study have a high level of subjective success, which is moderately high and indicates the satisfaction of the subjects with their own achievements and behavior. The professional self-efficacy of the managers under study has a moderately high value. Managers clearly formulate goals in their work and feel motivated to overcome all obstacles that stand on the way to a certain result. The identity of different levels managers researched is presented as follows: in the first place there is the professional role position (leader, entrepreneur, manager and specialist), then - family affiliation and roles in the family (husband, father, son, brother), personal qualities (reliability, stability , justice, sincerity, diligence), characteristics of activity ("study an interesting topic", "make your friends happy") complete the list of friendship criteria, existential self, self-assessment of social skills, description of your physical data, citizenship, ethnic and gender identity. Managers who have a larger number of subordinates, are close to the head of the company, and have a high level of professional self-efficacy, are more likely to consider themselves completely successful.
Portfolio Management in International Syndicated Lending
Authors: Tarasov A. A.
Published: February 2025

This article is aimed at presenting a wholesome approach to the management of a syndicated loan portfolio.

Methods utilized include the following: (i) portfolio analysis —  calculating the parameters of a syndicated loan portfolio (main, liquidity, diversification, and commercial parameters); (ii) measuring completion of the Key Performance Indicators (KPIs) —  comparing the actual values of the parameters of the syndicated loan portfolio to the target values of the KPIs and making the required managerial decisions; (iii) portfolio management — using the various syndicated loan market techniques with which a portfolio can be managed to achieve the completion of the KPIs (actively, passively, and via restructurings). Active syndicated loan portfolio management includes the execution of transactions in both primary and secondary syndicated loan markets. Cases of passive syndicated loans management relate to repayments of the syndicated loans in the portfolio: voluntary full or partial repayments based on the decisions of the borrowers; mandatory repayments when the borrowers have to fully or partially repay the syndicated loans based on the decisions of the lenders; scheduled repayment in accordance with the repayment schedules of the syndicated loans. The portfolio can also be affected by restructurings, when the lenders agree to change a number of major terms and conditions of the syndicated loans due to the circumstances of the borrowers.

In order to assess the results of the syndicated loan portfolio management, a managerial dashboard is built, an important accounting tool allowing for decision-making based on the comparison of the actual values of the parameters of the syndicated loan portfolio to the target values of the KPIs. An important issue in syndicated loan portfolio management is the monitoring of compliance of the borrowers with financial covenants: (i) the ratio of the Net Debt to EBITDA (earnings before interest, taxes, depreciation and amortization); (ii) the ratio of Net Interest Payments to EBITDA. In cases when the financial covenants or other terms and conditions of syndicated loans are violated, the borrowers can request the lenders with either waiver requests (for “one-off” issues) or amendment requests (for permanent changes). The process of handling waiver and amendment requests, including the involved parties, documents and timelines is reviewed.

The main conclusion involves combining of syndicated loan portfolio management results, financial covenant monitoring, and working on waiver and amendment requests in order to create the executive report, as well as the formalization of the general scheme for managing a portfolio of syndicated loans.
Understanding Xenophobic Attacks in South Africa: A Systematic Literature Review
Authors: Ngcamu Bethuel Sibongiseni
Published: February 2025

South Africa is seen as an intolerant country when it comes to black immigrants of African origin. The existing literature agrees with this narrative on the hostility and resentment faced by immigrants, but there is limited empirical data on the effectiveness of government interventions. This study, therefore, systematically reviews the literature on the common themes that define xenophobia in South Africa. It examines the literature on the impact of xenophobic attacks on victims and the effectiveness of government response strategies. The study’s findings demonstrate that peer pressure, failure to provide the promised basic needs to the citizens, and denialism by the government all contribute to the xenophobic attacks in South Africa. The government’s ineffective interventions and scapegoating are seen as exacerbating the impact of attacks against immigrants.

Published: February 2025

African intangible cultural heritage (ICH) is a rich resource for identity, community and sociality. Heritage institutions such as the Asafocompanies in Ghana, are traditional warrior groups that historically defended the state. Today, they are critical to coastal heritage management processes. This article reveals their contribution and argues that, while Asafo groups desire greater inclusion in heritage management, the national government of Ghana seeks to decentralize ocean governance processes. But, Asafo companies are complex groupings in which identity and “place,” matter. The article concludes that for a decolonial and sustainable ocean heritage management, the national government of Ghana needs to engage with Asafo companies to better understand them. In doing, so, the government will be better placed to support both a decolonial heritage conservation and ocean sustainability.

Os serviços ecossistêmicos constituem os benefícios que as sociedades obtêm a partir dos ecossistemas. Diante disso, o presente estudo teve como objetivo levantar os serviços ecossistêmicos da Caatinga percebidos por alunos da Escola Municipal de Ensino Fundamental Joventino Batista Monteiro e listar as espécies conhecidas da fauna e da flora. Para tanto, foram aplicados questionários semiestruturados com 38 alunos da modalidade Educação de Jovens e Adultos (EJA) e, posteriormente, realizada a análise dos dados obtidos. Os serviços citados pelos alunos foram classificados por meio da Common International Classification of Ecosystem Services (CICES), e as espécies foram identificadas por intermédio do Sistema de Informação sobre a Biodiversidade Brasileira (SIBBR). Os resultados mostraram a percepção sobre a oferta de cinco serviços ecossistêmicos de provisão. Em relação às espécies, foram listadas 32 espécies de plantas, 14 espécies de mamíferos, 31 espécies de aves e 07 espécies de répteis. Por fim, também foram apontadas 08 ameaças aos ecossistemas da Caatinga no município. Assim, registrou-se a percepção sobre serviços de provisão, amplo conhecimento de dois grupos de espécies e consciência sobre a degradação ambiental. Foram identificadas lacunas sobre serviços de outras categorias e espécies de mamíferos e répteis. Dessa forma, práticas pedagógicas que contemplem esses serviços e outras espécies podem desenvolver o pensamento crítico dos alunos sobre as formas de uso dos recursos naturais.
DESENHO E DINÂMICA INTRAURBANA DE UMA VILA NO RECÔNCAVO BAIANO SETECENTISTA À LUZ DA CARTOGRAFIA/ICONOGRAFIA HISTÓRICA
Authors: Adriano Bittencourt Andrade
Published: February 2025

Este artigo analisa a dinâmica intraurbana da vila de Nossa Senhora do Rosário do Porto da Cachoeira, erigida em 1698, no Recôncavo baiano. À luz de pesquisa documental e secundária, apresenta a rede urbana regional e destaca a principal nodalidade interior. O texto avalia a morfologia urbana a partir da iconografia feita pelo Juiz de Fora, Joaquim de Amorim Castro, no ano de 1792. Objetiva destacar as principais unidades construídas e estabelecer linhas de análise sobre a dinâmica territorial no interior da vila e dela com a sua região. O artigo traz como resultados a apresentação dos elementos constitutivos da sede da vila de Cachoeira e os tênues os limites e intensas ligações entre as pequenas sedes das vilas (formações urbanas) e o imenso espaço rural mais populoso, produtivo e onde se encontrava disperso o poder econômico e político da região. Conclui que a formação urbana não era apenas a sede da vila em si, mas ela e os liames, materiais ou não, que a entrelaçavam com o espaço povoado/produtivo contíguo. As decisões ali tomadas se propagavam pelo território da vila fazendo com que a extensão simbólica, política e administrativa fosse para além da base material da sua sede.

Assim, a pesquisa foi realizada na cidade de Barreirinha-AM, sendo verificadas as dificuldades enfrentadas e os serviços utilizados pelos idosos da localidade. Para isso, utilizou-se informações de fontes secundárias representadas em formas de tabelas e gráficos. Além disso, foi feito o diagnóstico da infraestrutura urbana com base no conceito da Cidade Amiga do Idoso.  Os resultados mostram que residem no município 2.531 idosos em 2022 e  que durante o período das cheias 90% das vias ficam submersas, implicando diretamente na mobilidade da população idosa local. O acesso ao comércio e aos serviços são prejudicados e as pontes de madeira não garantem segurança aos idosos. Porém, a recente revitalização do sistema viário da cidade possibilitou, em um certo grau, a mobilidade desses indivíduos na cidade. As obras representam um avanço para este público, para a economia local e aproxima Barreirinha e, portanto, ao conceito de Cidade Amiga do Idoso. Dentre as políticas públicas voltadas à população idosa da cidade, destacam-se o programa Tratando em Casa e demais projetos de inclusão dessa faixa etária à vida social da cidade.

Published: February 2025

Esse texto apresenta as experiências e os resultados do subprojeto "Lixo Urbano e o engajamento dos estudantes da periferia de Manaus", desenvolvido no âmbito do Programa Institucional de Bolsa de Iniciação à Docência (PIBID), no curso de Geografia da Universidade Federal do Amazonas, com a turma do 6º ano da Escola Municipal Raul de Queiroz Menezes Veiga, localizada na zona leste da cidade de Manaus. O tema relacionado ao lixo é relevante no período contemporâneo, pois a sociedade, em seu modo de produção com intenso consumo de mercadorias, ocasiona problemas estruturais nas cidades e gera resíduos sem um sistema capilar e eficiente de coleta, os quais são despejados em diversos lugares, contribuindo negativamente para a poluição desses locais. Nesse contexto, foi desenvolvido, no período de março a novembro de 2023, o subprojeto mencionado, que teve como ênfase apresentar aos estudantes o cenário do lixo em escala global e local, realizando atividades lúdicas e práticas visando estabelecer uma conscientização ambiental e geográfica. Destacam-se as experiências didático-pedagógicas que foram realizadas, incluindo atividades que visavam trazer o debate sobre o lixo para a escola, buscando reduzir a existência de desinformação por parte dos estudantes. Por fim, identificou-se que as atividades realizadas contribuíram para a compreensão do tema por parte dos estudantes.

- O presente artigo tem como objetivo mostrar o papel da geografia na mediação e resolução conflitos territoriais de uma área de litígio envolvendo a Terra Indígena Pantaleão, alvo de disputa entre a Fundação Nacional do Índio e o Município de Autazes-AM mediante solicitação da Justiça Federal do estado do Amazonas em 2018. No ano de 1989 a FUNAI iniciou uma Ação de Reintegração e de Posse em favor do povo Mura porque o município de Autazes desde sua criação em 1955, estabeleceu a sua sede, dentro da Terra Indígena Pantaleão já demarcada em 1918 pelo antigo Serviço de Proteção ao Índio habitada pelo povo Mura. Da metodologia usada constam o levantamento bibliográfico da literatura e documental de dados históricos incluindo mapas das outras terras indígenas demostrando a ocupação ancestral deste povo na região do Rio Madeira e trabalho de campo, em instituições públicas com observação direta, oficinas de gestão do conhecimento, registros fotográficos e georreferenciamento do  limites da Terra Indígena Pantaleão O estudo demonstrou que a ocupação territorial ancestral do Povo Mura, na região do Rio Madeira, Amazonas e Purus, atual Autazes, Careiro da Várzea, Borba e Itacoatiara, é legitima especificamente na área objeto da causa em questão.
GLOBALIZAÇÃO E A INDÚSTRIA FONOGRÁFICA: ALGUNS IMPACTOS DO K-POP NA CIDADE DE MANAUS - AM
Authors: Menezes de Seixas Camilli Victorine
Published: February 2025

A difusão global do K-pop é resultado da ascensão econômica da Coreia do Sul que por sua vez impulsionou a indústria fonográfica e de entretenimento. Essa intensa expansão da música pop sul-coreana reflete a globalização e o ápice do capitalismo, enquanto a interatividade online e eventos presenciais fortalecem os laços da comunidade de fãs, até mesmo na Amazônia, demonstrando a abrangência global desta cultura. Portanto, propõe-se compreender, por meio de uma perspectiva geográfica, os impactos do K-pop na cidade de Manaus tomando como ponto de partida os efeitos da globalização. Para isso, foram realizadas pesquisas em fontes bibliográficas a fim de constituir um levantamento teórico sobre o tema, enquanto para elaborar o mapa de distribuição espaço-temporal dos eventos de K-pop que ocorrem na cidade de Manaus, foram utilizadas fontes jornalísticas de divulgação em massa online juntamente com outros estudos.Como resultado foi possível observar que, o boom do K-pop no Brasil começou em 2010,especialmente entre mulheres jovens. Na cidade manauara, existe uma base de fãs crescente,evidenciada pela expansão de eventos inicialmente centrados nas áreas urbanas principais, mas queagora se descentralizam, alcançando áreas periféricas. Isso demonstra uma tendência dedescentralização e expansão da influência da cultura K-pop no Brasil.

Published: February 2025

A evasão escolar é caracterizada pelo abandono escolar durante o período letivo, impossibilitando que o conhecimento dos(as) estudantes sejam construídos adequadamente mediante as faixas etárias. Sabe-se que apesar da democratização da educação brasileira, a estrutura educacional evidencia formas de desigualdade social, sob as quais os estudantes se veem obrigados a abandonar a escola mediante a necessidade das demandas socioeconômicas associadas ao mercado de trabalho, para compor a renda familiar, fato que consiste em um dos condicionantes da evasão escolar. Neste sentido, a presente pesquisa teve como finalidades identificar quais fatores internos e externos à escola inviabilizam a conclusão do ensino básico. Para a condução da metodologia, utilizou-se a análise quantitativa, com a aplicação de questionários semiestruturados, com perguntas abertas e entrevistas com gestores, corpo docente e discente de uma escola da modalidade de Ensino de Jovens e Adultos (EJA), localizado na zona leste da cidade de Manaus.  Os resultados indicaram que 58,3% dos participantes identificaram-se como mulheres e 41,7% como homens. As respostas remeteram-se ao abandono escolar por motivo de gravidez e filhos no caso do sexo feminino. Sobre as condicionantes associadas ao sexo masculino identificou-se que o motivo de abandono foi por necessidade de trabalho e reprovações.

THOMAZ ESPÍNDOLA: UM "HOMEM DE SCIENCIA" E A GEOGRAFIA NA PROVÍNCIA DAS ALAGOAS NO NORDESTE DO BRASIL NOS MEADOS DO SÉCULO XIX
Authors: Nunes Silva Pedro Henrique , Teles de Carvalho Antonio Alfredo
Published: February 2025

A figura e a obra de Thomaz do Bomfim Espíndola (1832-1889) inserem-se em um contexto em que Alagoas vivenciara profundas transformações políticas, decorrentes, sobretudo, de sua emancipação da província de Pernambuco, em 1817. Nesse sentido, proceder à elaboração de uma imagem autônoma de Alagoas em relação a Pernambuco se constituía em um imperativo. Nesse contexto, Thomaz Espíndola, ao lado de Antonio Joaquim de Moura, é reconhecido como um dos fundadores da historiografia alagoana, bem como da sua geografia. Nascido em Maceió e graduado pela Faculdade de Medicina da Bahia (1853), Espíndola integrou um seleto grupo de intelectuais alagoanos ligados ao poder senhorial, destinados a pensar a província e a escrever sobre a mesma. Assim, buscou-se no presente trabalho, refletir acerca de como os escritos de Espíndola contribuíram para a construção e consolidação de uma imagem autônoma das Alagoas após a sua emancipação de Pernambuco.
