El objetivo del estudio fue identificar el nivel de propensión a la agresión física en personas mayores de 12 años. Se construyó un instrumento con 40 reactivos, considerando los principales factores asociados a la agresión física. El instrumento se aplicó a una muestra seleccionada por conveniencia de 304 personas, en el estado de Sonora, México. El Alfa de Cronbach obtenido fue 0.86, registrándose un nivel muy alto de confiabilidad y un KMO de 0.84 confirmó una alta relación entre las variables. La población estudiada concentra el 87.50 % entre un nivel bajo de agresión física y un nivel medio de agresión física. Las mujeres presentaron mayor porcentaje en el nivel bajo de agresión física (46.15 %) y los hombres en el nivel medio de agresión física (48.67 %). Se observó además que los mayores niveles de propensión a la agresión física se registraron en participantes con edades comprendidas entre los 14 y 17 años. Ello invita a considerar el diseño y desarrollo de programas de prevención dirigidos a adolescentes y jóvenes, con el fin de evitar comportamientos antisociales y delictivos y a la vez, favorecer la integración y la convivencia social.

Published: January 2022

Talvez não seja arriscar demais sugerir que o ano de 2017 venha a ser conhecido como um ponto de inflexão no fenômeno da internacionalização do ensino superior no Brasil. Se não no país, pelo menos em Minas Gerais, a mobilização em torno do tema sugere que a internacionalização entrou na pauta dos assuntos estratégicos e urgentes. Em um contexto de recessão econômica e contingenciamento das despesas, houve um redirecionamento do foco, não só em termos de metas, como de formas de financiamento. A mudança de paradigma ficou clara no seminário realizado pela Coordenação de Aperfeiçoamento de Pessoal de Nível Superior para anunciar o lançamento do Programa Institucional de Internacionalização – CAPES PrInt.

Une dynamique de coopération entre établissements concurrents dans le cadre d’une alliance peut transformer la digitalisation de l’enseignement supérieur. Le concept mobilisé est l’alliance stratégique dans le cadre de la théorie de la rupture de Christensen (1997). L’évolution tant du modèle économique que du modèle académique a permis d’une part de légitimer l’activité académique dans les milieux de l’enseignement supérieur, d’autre part de développer de la visibilité internationale via entre autre les classements. L’efficience de la gestion des ressources digitalisées permet d’anticiper l’émergence d’alliances entre établissements, basées sur la confiance et la qualité relationnelle. Dans une étude comparative historique, triangulée par des entretiens auprès de témoins, deux alliances entre écoles de commerce et écoles d’ingénieurs illustrent les coopérations autour de la pédagogie.

With a Fourth Industrial Revolution making inroads, encompassing all sectors of the industry with numerous concepts of disruptive technology such as Artificial Intelligence, Blockchain, Virtual and Augmented Reality, Internet of Things (IoT), Robotics and 3D Printing we have barely scratched the surface of its Scope, Implication, and Applications in various branches of the Construction Industry. This research aims to investigate the potential of Blockchain technology in the context of Smart Contracts and Supply chain management (SCM) applications in the construction sector. Most of the time, cost overruns have been attributed to the sluggish pace of contractual impediments or inefficacy of material and machinery procurement processes. The executive of material and data stream is a crucial need for development organizations. Effective execution in these regions can give significant benefits and permit more main incentives for customers. The industry is regularly censured for being delayed to grasp the change it needs and at the exact moment has been referred to as ready for the interruption because of the intricacy of work and a sheer number of guidelines and gauges, trust and check issues in regards to consistency to work principles still loom to a great extent. The momentum built by BIM infusion in the industry could be leveraged to bring Blockchain technology to the fore to mitigate Information Asymmetry by -distributing information to generate decentralized consensus building among various stakeholders involved.

This paper demonstrates the validation and prediction of the wall temperature of a building exposed to a composite climate. Two artificial intelligence models, such as multiple linear regression and artificial neural networks, have been used to predict. The wall temperature has been predicted mainly based on the parameters like ambient temperature, wind speed and relative humidity in all four directions of the buildings. Three statistical analyses were used to validate the model's outcome: R-Squared, Root Mean Square Error (RMSE) and Mean Absolute Error (MAE). In terms of train and control data, the two models yield comparable findings. The artificial neural network model has more adaptability since it was able to adjust to unexpected changes in the input data, according to a comparison of the applied mathematics of each model. The regression model was used for this investigation because it gives constant estimate values for the factors, though the neural model isn't numerically characterized. The review infers that the neural model must be utilized as an additional way to predict the wall temperature. This study can plan and adapt buildings for future work, considering the most critical climatic conditions. It also assists architects and engineers in determining the appropriate insulation for the building envelope, which improves its thermal performance.

Earthquake is a natural disaster that occurs when the Earth's crust moves suddenly. Every year, hundreds of earthquakes strike various parts of the globe. According to previous research, buildings that are built on sloped terrain are the most susceptible to earthquakes. This is attributable to the different heights of the columns on the ground floor. By changing the height of the column at the base of a 2-D Conventional RCC Frame and a Special Confined RCC Frame, an experimental investigation was carried out in this study. The parameters like load verses deflection, crack width and stiffness degradation was used to draw comparison between the Conventional RCC Frame and Special confined RCC Frame under Reverse Cyclic Loading by using Push and Pull Jack. Hysteresis curve clearly shows that Special Confining reinforcement provided for the column throughout the span because of columns with varying stiffness provides additional strength and performance against lateral force by dissipating energy. The ductility of Short column improved at initial stage, meanwhile the displacement of the Special confined RCC frame with short column also improved due to ductile reinforcement which leads to reduction in failure rate and arrest the sudden failure of the short columns in the frame as that is physically visible from the crack pattern.

Reinforced concrete structures collapse by developing tensile and flexural crack patterns. The properties of the concrete must be researched to prevent these forms of failure and enhance the overall strength and durability. The inclusion of fibres in the concrete increasing the strength of the concrete and prevents micro-cracks that lead to a major failure. In this study, two different types of fibres are considered for inclusion in the concrete as Hybrid fibre in which one has higher moduli (Steel fibre) and one has lesser moduli (Polypropylene fibre). This hybrid material formulation can reduce the probability of brittleness and micro-cracks forming in concrete. The mix design used for this investigation is M40 grade of concrete designed as per IS10262:2019. The hybrid combination of Steel and Polypropylene fibre ratio is 50:50 with different hybridization percentages as 1%, 1.5% and 2%. The compression, splitting tensile and flexural tests were carried out to study the hybrid concrete behavior for the three different hybridization dosage percentages and the same were carried out for the controlled concrete. The experimental study revealed that the inclusion of the hybrid fibre increases the strength of the concrete compared to the conventional concrete. The hybridization of 1.5 % gives the higher strength results and it is considered as an optimum percentage.

The addition of natural fibers in concrete has effectively proved to increase the mechanical strength and durability of concrete in the recent years. They help to tackle the brittle response and limiting post-yield energy absorption by forming a bridge across the cracks in concrete. This study assesses the durability properties of abaca fiber reinforced concrete (AFRC) by surface water absorption test, rapid chloride permeability test (RCPT) and sorptivity test. The optimum percentage of abaca fiber (AF) to be used was chosen to be 0.5 % as it gave the maximum compressive strength value in concrete and a small amount of superplasticizer has been added to reduce the water content in the mix design to match the high water absorption capability of AF. The respective tests were performed to observe the improved properties of water resistance and resistance to chloride ions penetration after 3, 7, 28, 56, 90 and 180 days of curing. It has been found that the addition of AF enhances the ability of concrete to reduce permeability better compared to the effect of conventional concrete (CC).

Flexural behaviour of high-performance concrete (HPC) was affected by various parameters and plays a vital role in the strength of concrete. Present study aims in deciphering the role of cyclic loading on HPC reinforced with steel fibers. The study was carried out by casting of beams with hooked end steel fiber reinforced concrete with various grades (M60, M80, M100) and with admixtures (GGBS and Silica fume). Cast beams were studied for compressive strength, tensile strength, and flexural strength under cyclic loading. The study shows that there was a significant increase in compressive strength of HPC mixed with 1.0% of steel fiber. Flexural strength was found to be comparatively higher (upto 15% for all grades) for 1.25% steel fiber mixed HPC. Direct tensile strength is found to be higher than split tensile strength. Addition of steel fiber in HPC beam under cyclic loading, resulting in delayed or late development of cracks with decreased crack size.

Published: January 2022

In process industries, the heating gap in heat exchanger networks (HENs) is normally compensated by the steam generated from a utility system, thus these two mutually influencing systems should be designed as a whole through establishing structural interrelationships. In this work, an improved stage-wise superstructure of HENs is proposed to integrate with a Rankine cycle-based utility system. Inner- and inter-stage heaters are considered in the new structure. Furthermore, the selection of steam in different levels is also investigated, extending the possibilities of steam utilization in HENs and generation in utility systems. The presented methodology is able to realize the optimal design of HENs by considering the supply and utilization of steam. Heaters’ allocations, matches of streams, steam distribution and utilization are optimized accompanying with the trade-off amongst equipment investment, fuel consumption and power generation in objective, which is highly related to the final structure of the system. The optimization problem is formulated into a mixed-integer non-linear programming (MINLP) model and solved towards the lowest total annual cost (TAC) of the entire system. Finally, a case study with two scenarios is studied. The detailed results are given and analyzed to demonstrate the benefit from structural improvement.

O monitoramento das unidades de conservação (UCs) é fundamental para avaliar seatingem seus objetivos. Felinos são bons indicadores ambientais e suas fezes podem fornecer informaçõesrelevantes para o monitoramento de UCs. Utilizamos fezes encontradas em trilhas do Parque Nacionalda Serra dos Órgãos para registrar a presença de felinos e outros mamíferos, analisamos sua distribuiçãoespacial e discutimos o potencial do uso dessas amostras como ferramenta de monitoramento ambiental.Entre 2009 e 2019, foram coletadas 486 amostras em 21 trilhas. Foi possível identificar um mamífero em61% das 315 amostras analisadas por microscopia óptica dos pelos-guarda. As cinco espécies de felinoscom ocorrência confirmada no parque foram registradas, com destaque para o gato maracajá (Leoparduswiedii), frequentemente registrado em altitudes mais elevadas que o conhecido. Foram identificadosmamíferos com poucos registros anteriores no parque, como o mão-pelada (Procyon cancrivorous).A distribuição espacial das amostras reflete a altimetria da área amostrada, com uma concentração noscampos de altitude, onde outros métodos têm-se mostrado menos eficazes no registro de mamíferos,destacando-se a importância de usar métodos complementares de monitoramento. Fezes podem serutilizadas em análises moleculares, que, além de refinar a identificação taxonômica, podem desvendarinformações como o grau de isolamento genético das populações. As fezes podem fornecer informaçõessobre a saúde animal através do estudo de parasitos gastrointestinais, que também são bons indicadoresde qualidade ambiental e sobre contaminação ambiental. Apesar de seu potencial, o uso de fezes defelinos como ferramenta de monitoramento ainda é raro.

Este estudo expõe o manejo dos produtos florestais não madeireiros (PFNMs) como fator gerador de renda com o intuito de fortalecer e contribuir com a atividade extrativista realizada pela Cooperativa de Extrativistas de Carajás na Floresta Nacional do Tapirapé Aquiri (FLONATA). Para isso, realizou-se uma revisão sistemática com o auxílio da base de dados Web of Science e a partir dos filtros: data de publicação (2016 a 2020), palavra-chave “non-timber forest products” e origem (espécies brasileiras). Foram identificadas as principais espécies estudadas, o periódico de publicação, região de concentração das pesquisas, metodologia utilizada e seus principais usos com o objetivo de subsidiar o estabelecimento de novas cadeias produtivas dentro da FLONATA. Foram encontrados 564 estudos que abordavam aspectos relacionados aos produtos florestais não madeireiros no mundo, e desses, um total de 72 foram realizados no Brasil e apenas 56 apresentavam, prioritariamente, um uso não madeireiro para alguma espécie. Esses mesmos estudos propiciaram o levantamento de 16 famílias botânicas e 47 espécies com uso não madeireiro, onde 39 ocorrem naturalmente na Floresta Nacional do Tapirapé Aquiri, como é o caso da castanha-do-Pará (Bertholletia excelsa Bonpl.) e do açaí (Euterpe oleracea Mart). O levantamento dessas espécies com potencial de uso não madeireiro juntamente a especificidade de seus estudos como é o caso de informações ligadas a ecologia, fenologia, botânica entre outras áreas que caracterizam individualmente tal espécie, fomentam futuras possibilidades de uso contribuindo para o estabelecimento de novas cadeias produtivas e para a conservação da floresta.

Authors: Barbosa Janderson James , Leal Afonso Henrique
Published: January 2022

A Reserva Biológica Guaribas é uma unidade de conservação de proteção integral gerida pelo Instituto Chico Mendes de Conservação da Biodiversidade (ICMBio) e tem como objetivo a conservação integral da biota. Situando-se no litoral norte da Paraíba, apresenta mais de 4.000ha divididos em três áreas, denominadas SEMA 1, 2 e 3, sendo a SEMA 2 o maior fragmento de Mata Atlântica entre os estados da Paraíba e Rio Grande do Norte. A unidade de conservação (UC) encontra-se em uma área de forte cultivo de cana para produção de açúcar e álcool, o que o que eleva o risco de incêndios na vegetação nativa devido a prática da queima pré-colheita, principalmente na estação seca, que ocorrem dos últimos meses do ano aos primeiros do ano seguinte. O estudo compila informações contidas nos Registros de Ocorrência de Incêndios (ROI) entre os anos de 2007 a 2018 e reconhece o perfil quantitativo dessas ocorrências, identificando a distribuição geográfica dos incêndios, os tipos de vegetação atingidos, as causas do fogo, e apresenta propostas para prevenir e combater esses eventos. No período de estudo, foram produzidos 290 ROI, correspondendo a 1251,70ha em área queimada, dos quais 101,93ha foram dentro da UC. Dos incêndios registrados, 93.4% aconteceram fora da UC, desses, 21% ocorreram além da zona de amortecimento. Novembro mostrou-se o mês mais propício ao fogo com 87 registros, e 2012 foi o ano com a maior área da UC afetada, com 27,62ha queimados. Os tipos de vegetação mais atingidos foram, respectivamente, capoeira (aberta e fechada) e mata madura. Além disso, as causas, com poucas exceções, foram antrópicas, das quais práticas agropecuárias e vandalismo figuraram como as mais comuns na região. As áreas menores (1 e 3) apresentaram proporcionalmente maior quantidade de incêndios imediatamente ao entorno. Por fim, foi observada uma forte concentração de incêndios logo ao norte da SEMA 1.

Caracterizar a estrutura do habitat, identificando a funcionalidade de espécies arbóreas, é uma estratégia importante para auxiliar programas de manejo. Este estudo objetivou caracterizar a estrutura do habitat, identificar a composição ecológica e o tipo de síndrome de dispersão das árvores em fragmentos habitados pelo ameaçado de extinção Callicebus coimbrai, Mata Atlântica em Sergipe. Foram percorridos oito transectos pelo método do quadrante errante, com 780 pontos registrados em 3.166,71m percorridos. Em cada ponto, coletamos o DAP, altura, distância entre dois pontos (árvores), além da identificação da espécie de árvore. Analisamos abundância, densidade, frequência, dominância basal, índice de valor de importância, além do cálculo do índice de diversidade e equitabilidade de Pielou. A distância média entre as árvores foi de 4,05±2,75m, a altura média foi de 11,69±3,10m, e o DAP médio foi de 25,75±13,53cm, com poucas diferenças significativas entre os fragmentos. Em geral, as estruturas são pobres e a composição das árvores é formada principalmente por espécies pioneiras e secundárias iniciais, e espécies com síndrome de dispersão zoocórica. Esses locais apresentam uma estrutura instável para os macacos guigós habitarem. Além disso, estão distantes de outros locais, dificultando a movimentação dos indivíduos. Esses resultados mostram a importância de caracterizar a estrutura, utilizar os traços ecológicos das árvores como medida da qualidade do habitat, auxiliando programas de manejo que visem a preservação e conservação de espécies ameaçadas e seus habitat.

Published: January 2022

Callithrix aurita é um pequeno primata endêmico da Mata Atlântica brasileira e considerado “em perigo” de extinção (EN) devido à perda e fragmentação de seus habitat e à competição e hibridação com congêneres invasores. Nesse contexto, identificar fragmentos florestais habitados por Callithrix spp. é uma das estratégias prioritárias para a sua conservação. Como as populações de C. aurita podem estar subamostradas pelas diversas técnicas de detecção, o objetivo deste trabalho foi avaliar a eficiência do playback como método auxiliar à busca ativa de Callithrix spp. em fragmentos da microrregião de Viçosa. Para tal, considerou-se a taxa de resposta de Callithrix spp. em relação ao tamanho do fragmento e o horário do dia. Quinze fragmentos foram vistoriados, com 88 pontos de playback. Não houve registro de C. aurita, mas houve resposta de Callithrix spp. em 5,68% das execuções. As respostas foram obtidas entre 07h - 08h ou entre 16 - 17h. As maiores taxas de resposta de Callithrix spp. ocorreram em fragmentos maiores que 100ha, seguido por fragmentos entre 50ha e 100ha, e por fragmentos menores que 50ha. O horário do dia está intimamente ligado à temperatura; portanto, os horários de maior responsividade ao playback são corroborados pelo fato de haver perdas abaixo do esperado na propagação do som. Não houve interferência significativa da área do fragmento e do horário nas respostas de Callithrix spp. Assim, a técnica de playback demonstrou-se útil para levantamentos de Callithrix, independentemente de seu tamanho, em especial quando executado no início do dia ou fim da tarde.

Os quelônios são animais de vida longa e poucos dos seus indivíduos chegam à fase adulta. Além da baixa taxa natural de recrutamento, diversas ações antrópicas vêm dificultando a manutenção das populações desse grupo. A exploração desordenada para abastecer o comércio ilegal vem se mostrando a mais danosa, principalmente em Podocnemis expansa, por ser uma espécie bastante apreciada na culinária amazônica, e muito vulnerável no período reprodutivo, época de maior captura. Seu histórico de exploração causou desequilíbrio populacional em diversas localidades na Amazônia, como pôde ser verificado durante as quase três décadas de monitoramento em importantes sítios de desova em unidades de conservação do rio Araguaia. O presente estudo desenvolveu marcadores moleculares com o objetivo de testá-los e compará-los com primers já utilizados, além de avaliar a diversidade genética e a estruturação populacional de P. expansa na bacia Tocantins-Araguaia. Para isso, foi coletado tecido cutâneo de 120 espécimes amostrados em três localidades no médio e submédio rio Araguaia, comparados com sequências do DNA mitocondrial de 22 localidades. A região controle do DNA mitocondrial de P. expansa é de difícil amplificação, sendo que o par de primers de outros estudos não amplificou com o material biológico utilizado neste trabalho, mostrando a eficiência do marcador molecular confeccionado. A utilização desses primers facilitará a amostragem em campo, pois, apesar de o tecido cutâneo conferir menor quantidade de DNA extraído quando comparado ao tecido sanguíneo, sua coleta como material biológico pode ser aplicada de forma mais simples, ampla e frequente em projetos de pesquisa e programas de monitoramento e manejo de quelônios, facilitando as pesquisas genéticas com esses animais. Quanto à avaliação genética, foi caracterizada panmixia na bacia Tocantins-Araguaia e baixa diversidade genética, concordando com dados da espécie. Caso as estratégias de conservação não sejam eficientes para reverterem um provável processo de deriva genética, poderão ocorrer prejuízos populacionais significativos, notadamente quanto às questões adaptativas da espécie.
Determinants of Maize Production Income in Western Uganda
Authors: Chune Midamba Dick
Published: January 2022

Many smallholder farmers produce maize for both consumption and income purposes. Despite the role played by maize, its income production is low, especially in developing countries. In order to formulate policies targeting maize productivity, it was necessary to have knowledge of the determinants of maize production income. As such, this study aimed at determining the level of income and its determinants from maize farmers. Consequently, data was collected from 220 maize farmers using structured questionnaires. The ordinary least squares model was used to determine the determinants. The results showed that the farmers earned a mean of 372,207 Ugandan shillings (105.18 USD) from maize production. Accordingly, farm size, access to credit and household size had a significant positive influence on income from maize production, while gender (female) of the household heads had a significant negative relationship with income from maize production. It is based on these results that this study recommended that the government should offer training programs targeting female-headed households. These trainings should incorporate farm production as well as marketing. Additionally, farmers should be encouraged to access various sources of agricultural credit including financial institutions that offer agricultural loans at low-interest rates.

Цивілізаційний поступ людства переконливо засвідчує, що обдаровані особистості генерують левову частку світових інновацій та є рушійною силою стійкого розвитку людського капіталу, світової економіки і науки. Відповідно розвиток обдарованих особистостей є пріоритетним завданням країни. В Інституті обдарованої дитини НАПН України досліджують феномен обдарованості, здійснюють методичне забезпечення діагностики обдарованості та розвитку її структурних складників, створюють програми й методики розвитку обдарованої особистості на різних вікових етапах, розробляють теоретико-методичні засади спеціалізованої освіти наукового спрямування тощо. Учені Інституту запропонували новий підхід до розуміння обдарованості як єдності розумової, духовної та фізичної сфер особистості. Також розроблено оригінальні та адаптовано зарубіжні методики виявлення обдарованості в учнів, створено профорієнтаційно-діагностичну тестову систему. Встановлено, що формування в учнів умінь отримання знань з використанням дослідницьких методів є найбільш ефективним фактором розвитку тих складників обдарованості, які підпадають під педагогічний вплив. Як наслідок, вчені Інституту сприяють імплементації в освітній простір України парадигми наукової освіти та концепції спеціалізованої освіти наукового спрямування.
