Masculinidades, violencias y justicia penal
Authors: Papalía Nicolás Juan
Published: April 2024

En este libro se plantea la necesidad de revisar el trabajo desarrollado desde el sistema de justicia penal sobre la violencia de género, incluyendo la perspectiva de los varones como cuestión central para definir respuestas integrales y efectivas. En este sentido, se sistematizan minuciosamente los estándares normativos y las políticas públicas en la materia. Además, de manera innovadora, se identifican las representaciones que circulan entre las y los agentes del sistema de justicia penal respecto de los varones denunciados, para poner en evidencia lo que acontece efectivamente en la práctica judicial.

El trabajo señala la relación intrínseca entre la construcción de los modelos sociales de masculinidad y las violencias, así como la necesidad de deconstruir dichos modelos como una forma de prevenir y abordar esta problemática. En esa dirección, aporta datos empíricos y promueve reflexiones acerca de los caminos a seguir para desentrañar las posibilidades de trabajo con los varones que ejercen violencia.

Authors: Marques Willian da Silva , Pineli João Pedro Gentilin , Silva Gabriel Deringer da , Higa Márcio
Published: April 2024

A grande demanda de potência elétrica em sistemas de refrigeração industrial operando por compressão estabelece a necessidade para que estas plantas operem com bom desempenho térmico. Entretanto, devido aos limites nos recursos investidos, às adaptações muitas vezes realizadas com urgência nas instalações de novos componentes, e outras dificuldades técnicas, nem sempre é possível que os sistemas operem nas melhores condições. Por esta razão, a análise de projetos existentes é importante para se verificar possíveis melhorias que podem ser implementadas, sejam estas para evitar o desperdício de energia, ou mesmo para se integrar tecnologias alternativas não convencionais. Neste contexto, este trabalho se propôs a analisar um sistema de refrigeração industrial de um frigorífico adotado como estudo de caso, em que foram realizadas 2 propostas. A proposta 01 refere-se a uma readequação dos componentes e correntes térmicas do sistema para reduzir o consumo de potência. Já a proposta 02 analisou o aproveitamento de calor do vapor saindo da compressão, antes da condensação, para integrar um sistema de absorção. As análises foram realizadas utilizando a Primeira Lei da Termodinâmica a partir dos balanços de massa e energia para cada componente do ciclo e com o auxílio do software Engineering Equation Solver. Os resultados, avaliados por meio de cálculos do coeficiente de desempenho (COP) e da potência elétrica economizada, apresentaram o aumento do COP em 3,1% na proposta 01 e 4,0% na proposta 02, demonstrando que tanto a readequação de correntes térmicas, como a integração do ciclo de absorção podem ser viáveis para melhorar o desempenho e reduzir o consumo de energia elétrica de uma indústria.

Published: April 2024

Um dos maiores desafios enfrentados pela sociedade civil é encontrar formas de preservar as fontes de água, livres de contaminações e adequadas ao consumo humano. Essa dificuldade está relacionada à contaminação dos lençóis freáticos em virtude da expansão urbana, sem o devido planejamento, tendo como consequência o uso e ocupação do solo desordenado. O presente trabalho objetivou avaliar a qualidade da água de dois poços localizados no município de Lábrea, situado no Instituto Federal de Educação, Ciência e Tecnologia do Amazonas (IFAM). Foram selecionados dois poços: a) o poço 1 (um) que está em atividade e localiza-se dentro do Instituto; b) o poço 2 (dois) (2) que está desativado e localiza-se na área externa ao Instituto.  Para a verificação dos parâmetros físico-químicos e microbiológicos, foram analisados os seguintes parâmetros: pH, Turbidez, Cor, Coliformes Termotolerantes, Coliformes Totais, Condutividade Elétrica, Nitrogênio Total, Fósforo Total, Demanda Bioquímica de Oxigênio (DBO5), Oxigênio Dissolvido e Sólidos Totais Dissolvidos, comparando os resultados com os padrões preestabelecidos pela legislação vigente. O poço 2 (dois), desativado, localizado na área externa, apresentou valores de alguns parâmetros acima dos estabelecidos pela legislação. A desativação desse poço é considerada uma medida apropriada, pois os resultados indicam que a qualidade da água não está em conformidade com os padrões estabelecidos.

As Plantas Alimentícias Não Convencionais (PANC) são vegetais com potencial alimentício de crescimento espontâneo, que demandam aprofundamento quanto à propriedade nutricional, para valorização de consumo e produção em escala industrial. A inserção de PANC na formulação de produtos alimentícios como barra de cereais, pode fomentar o interesse de um público ávido por novos produtos funcionais. O objetivo foi desenvolver e avaliar a estabilidade de barra de cereais formulada com PANC submetida à irradiação por Cobalto-60. As barras de cereais foram submetidas a diferentes doses de irradiação (0,5; 1,0 e 2,0 kGy), seguido de armazenamento por 90 dias a 25°C, com retiradas de amostras mensalmente para análises de estabilidades físico-química e microbiológica. Os dados foram avaliados pela análise de variância e comparados pelo teste de Duncan (p<0,05). A aplicação da irradiação nas barras de cereais com PANC não provocou perdas expressivas dos constituintes nutricionais. Todas as amostras atenderam os parâmetros microbiológicos exigidos pela legislação vigente, demonstrando a associação entre as condições higiênico-sanitárias adequadas e as boas práticas de fabricação. A incorporação de PANC atribuiu qualidade nutricional e a irradiação aumentou a vida útil das barras de cereais. Portanto, as barras de cerais formuladas com PANC apresentam potencial comercial, e a irradiação sendo uma tecnologia viável de baixo custo pode ser utilizada em larga escala na indústria alimentícia.

Authors: Fonseca Wirven Lima da , Almeida Marllus Rafael Negreiros de , Silva Ageane Mota da , Machado Reginaldo Assêncio , Martins Marcio , Bernarde Paulo Sérgio
Published: April 2024

Snakes of the family Viperidae are distributed in many different ecosystems, generally being the most abundant species in snake surveys and studies on snake assemblages in Brazil. These species are medically important as they can cause snakebites and are responsible for approximately 99% of envenomings in humans in Brazil. Considering the ecological importance of snakes in terrestrial ecosystems, mainly as important predators in food webs, and in public health due to the risks of snakebites, here we review the information available in the literature about vipers in the state of Acre, western Brazilian Amazon. Six species of vipers were already recorded for Acre, with Bothrops atrox being the most abundant, present in various types of habitats and being the main species involved in snakebites. Bothrops bilineatus is the most common snake found in a floodplain forest in the protected area Japiim Pentecoste, a factor probably associated with prey availability. The other four species of vipers (Bothrocophias hyoprora, Bothrops brazili, B. taeniatus and Lachesis muta) are less frequent and associated with unflooded forests. Although we found in the literature several studies involving vipers in Acre, there is a need for more studies on these snakes in the region, addressing their ecology, ethno-herpetological questions and snakebites, including research on their ecology and behavior in the field, genetic variation and differentiation among populations and species, and biochemical composition of venoms.

Authors: Silva Levy Ruanderson Ferreira da , Gonçalves Tadeu Junior de Castro , Santos Ticiane Lima dos , Lacerda Liliana Farias , Carvalho Josué de Lima
Published: April 2024

Este estudo tem por objetivo verificar a percepção dos servidores públicos da administração direta e indireta do estado do Rio Grande do Norte (Brasil) no que diz respeito ao teletrabalho em época de pandemia Covid-19. Para atingir ao objetivo, foram aplicados questionários a servidores públicos do estado do Rio Grande do Norte, em que se obteve 567 respostas para análise descritiva e inferência estatística. Entre os achados, observou-se que houve adaptação dos colaboradores no que diz respeito ao teletrabalho, tendo em vista que 84% são favoráveis a implantação do teletrabalho na organização após a pandemia. Assim, de acordo com os resultados, quando questionados sobre o teletrabalho ser irreversível no setor público no futuro, 43% dos respondentes concordaram parcialmente. Quanto as limitações, destaca-se a pouca literatura relacionada ao tema, logo, faz-se necessário observar, de forma introdutória, se o teletrabalho aplicado no setor público, pode provocar condições que melhorem a produtividade e a eficiência de seus colaboradores e serviços prestados. Nesse sentido, é sugerido em pesquisas futuras que sejam observados fatores causados pelo isolamento social e a utilização de experimentos e modelos econométricos capazes de explicar a relação entre aumento de produtividade e eficiência com o teletrabalho no âmbito do setor público.

Authors: Flores Thayná Soares Guimarães
Published: April 2024

Trata-se de um estudo que tem por objetivo: analisar a percepção dos enfermeiros que atendem gestantes vítimas de violência doméstica no ambiente hospitalar; identificar as ações utilizadas pelos enfermeiros dentro da sala de parto para minimizar os agravos ocasionados pela violência doméstica; descrever estratégias utilizadas pelos enfermeiros para sentir-se preparados a identificar e atender gestantes vítimas de violência doméstica. Trata-se de uma pesquisa descritiva com abordagem qualitativa. Os dados foram coletados em novembro e dezembro de 2019 através de entrevista semiestruturada e tratamento dos dados foi utilizada a análise de conteúdo de Bardin. A pesquisa possibilitou compreender que mesmo os enfermeiros sem uma capacitação específica para esses casos, conseguiram prestar uma assistência humanizada e de qualidade para as gestantes que estavam sob seus cuidados. Outro resultado demonstrado foi a insegurança dos enfermeiros para atender essas clientes devido à falta de conhecimento teórico e um protocolo institucional no qual pudessem se basear. Com isso, conclui-se que é de extrema importância o aprimoramento dos enfermeiros em relação a essa temática, da mesma forma que precisamos de hospitais que invistam na qualificação e atualização de seus profissionais, estabelecendo normas institucionais que irão nortear seus funcionários a prestar uma assistência qualificada e embasada na teoria para os seus pacientes em qualquer situação de violência.

Interrogating Intercultural Communication in the Context of Hofstede's Cultural Dimensions: A Socio-Psychological Analysis of the Film ‘The Farewell’
Authors: Wang Qianqian
Published: April 2024

In today's academic research, both cross-cultural communication and the psychology of language have been extensively studied, yet research combining the two to explore phenomena in cross-cultural communication through the lens of psycholinguistics is not common. This study aims to fill this gap by examining the psychological dynamics of cross-cultural communication, focusing on Hofstede's cultural dimensions theory and applying theories of psycholinguistics to further investigate the psychological dynamics and subconscious influences in this cross-cultural process. Through an in-depth analysis of the movie "The Farewell," this research explores how cultural backgrounds influence individuals' and collectives' attitudes towards uncertainty and ambiguity, as well as the psychological reasons behind cultural dimensions. The movie primarily discusses the story of a Chinese-American protagonist, Billi, whose grandmother in China is terminally ill and unaware of her condition, around which a faux wedding is organized as a reason to visit her. This study deeply investigates the issue of the right to end-of-life information and other cultural conflicts presented in the film. Utilizing Hofstede's cultural dimensions theory, it delves into individualism versus collectivism, power distance, long-term versus short-term orientation, and uncertainty avoidance, to understand their impact on communication styles, emotional expression, and decision-making processes. The paper highlights the necessity of integrating cultural sensitivity and psychological flexibility in global interactions, contributing to a broader discourse on cultural psychology.

Reflections from "Death of the Author" to "Death of the Reader"
Authors: Wang Xudong
Published: April 2024

Roland Barthes put forward the famous literary theory of "the death of the author" in his masterpiece "The Death of the Author". Under the scope of literature and art, the discussion and debate about "the death of the author" has been enriched and deepened in the course of researchers' study. The intent of the literary theory of the "death of the author" is to remove the author's dominant position in the creation of the text in order to expand the scope of the meaning of the text itself and to enrich the space for the reader as an object of reception. Discussions about the theory itself have not only appeared in the fields of literary studies, literary criticism, and the history of reading, but have also generated new points of interest and focus along with cultural development, media changes, and social transformations. When the "death of the author" is re-examined and further extended to the reader's level, and combined with certain social realities, it will provide some new thoughts and inspirations for the study of literature.

Given that review helpfulness is a truncated variable, we employ Tobit regression models to evaluate the effects. The results indicate that both positive and negative sentiment contribute to review helpfulness. Moreover, there exists a positive association between informational support description and review helpfulness. When affecting review helpfulness, informational support description negatively moderates the impact of sentiment on review helpfulness.
Corporate Group Decision-making Authority Allocation and Digital Transformation
Authors: Sha Jingyu
Published: April 2024

With the continuous development of digital technology, the digital economy has become an important direction for economic development. At the micro-level, how to promote corporate digital transformation is a topic of common concern for academia and practitioners. This paper empirically tests the logical relationship between corporate group decision-making authority allocation and digital transformation using samples of A-share listed companies from 2010 to 2021. The research finds that decentralization within corporate groups significantly promotes digital transformation. Furthermore, for non-state-owned enterprises, high-tech enterprises, and companies operating in periods of monetary policy tightening or high industry competition, decentralization has a more significant effect on promoting digital transformation. The results are of great significance for corporate groups in determining appropriate decision-making authority allocation patterns to achieve digital transformation.
Optimal production decision and supply chain coordination under different capital conditions
Authors: Huang Fuyou , Gao Zhe
Published: April 2024

This paper investigates a two-level supply chain composed of a retailer and a manufacturer with budget-constrained. The manufacturer’s optimal production quantity is explored under different own capital conditions, and the gap between in the decentralized system with wholesale price contract and in the centralized system is discussed. Then, an option contract is used to investigate the supply chain coordination issue. The results show that, when the manufacturer has enough capital, both the production quantity and the expected profit in the decentralized system with wholesale price contract are less than that in the centralized system, and the gap between in the decentralized system and in the centralized system is increasing on the own capital. The option contract can coordinate the supply chain with budget-constrained, and in the presence of supply chain coordination, both the manufacturer and the retailer can become better off by setting reasonable option contracts. Several numerical examples are provided to demonstrate these finds.

Authors: Yu Zhichao , Jiang Changjun
Published: April 2024

With the rapid development of urbanization in China, rural production factors have gradually flowed to urban areas, which has exerted a negative impact on the development of agricultural economy. Government investment in agriculture and agricultural mechanization are key factors to solve the dilemma of agricultural development. Based on China's provincial panel data and PVAR model, this paper explores the relationship between financial support for agriculture (FSA), agricultural mechanization service (AM) and the development of agricultural economy (AE). The results show that that there is a long-term two-way causal and mutually promoting relationship between FSA and AE growth. The government investment in agriculture can increase AE in the short term, however, it is not effective in the long run. The effect of FSA on AE is more significant than that of AM, while the effect of FSA on AM is insufficient. It is suggested to formulate detailed plans for financial support for agriculture, strengthen agricultural land consolidation, build large farms, and optimize subsidy policies for the purchase of agricultural machinery.

A new method of Arps decline research - nonlinear fitting
Authors: Dai Jinyou , Zhang Yang , Zhao Shijia
Published: April 2024

Arps decline is widely used in the research and prediction of production decline law. At present, linear graphical is the conventional method of Arps decline research, which first determines the decline type and then determines the decline index. The judgment of decline type is subjective, and the determination accuracy of decline index is low, which affects the understanding of production decline law to a certain extent. Therefore, this paper proposes a nonlinear fitting for Arps decline research. The method determines the decline index first, and then determines the decline type. The accuracy of the decline index is high, and the judgment of decline type is more objective, which is conducive to the correct understanding of the production decline law. Taking Zizhou gas field as an example, the effect of two methods of Arps decline research is compared and analyzed, and the effectiveness of nonlinear fitting is verified, and good application results are obtained.

Authors: Lian Peng , Mu Yurong , Yang Wenbo
Published: April 2024

The sustainable utilization of tuna resources faces big challenges arising from extreme climatic and oceanic events. As one of the most important regions for global ocean-atmosphere interactions, the ecological effects of changes in the ocean environment in the Atlantic are always underestimated. Meanwhile, the tropical Atlantic Ocean (TAO), as an important fishing ground for tuna, is facing significant challenges to its ecological stability due to the dual pressures of climate change and human fishing activities. This study explores the spatio-temporal correlation and periodicity between sea surface temperature (SST) and tuna resources through the response patterns of three tropical tuna species to different regional marine climate indices. Research has found that there is a clear dipole pattern in the response of tuna to SST. This study provides insights into the changes in tuna resources over multiple years.
Performance analysis of a multi-tube exhaust waste heat recovery methanol reforming to hydrogen reactor
Authors: Li Weixing , Tang Yuanyou , Long Wuqiang , Xiao Ge
Published: April 2024

To address hydrogen storage and transport challenges, a methanol reforming hydrogen reactor featuring multi-pipe exhaust heat recovery was simulated using Fluent. Initial simulations focused on microscopic flow, heat transfer, and reaction dynamics within a catalyst particle stack. Subsequent macroscopic analyses of a comprehensive reactor model evaluated how reactant inlet velocity, molar ratio of steam to methanol vapor (S/M), exhaust temperature, and flow impact reforming performance. Findings indicate that smaller catalyst particles enhance heat transfer and reaction at the cost of increased pressure drop, with an optimal size of 4.4 mm. Methanol conversion correlates positively with S/M, exhaust temperature, and flow, but negatively with inlet velocity. Hydrogen production increases then decreases with S/M, showing positive correlation with inlet velocity, exhaust temperature, and flow. Carbon monoxide selectivity is inversely related to inlet velocity and S/M, and positively to exhaust temperature and flow.

Research and Comparison of Fire Detection Models Based on Deep Learning and Mixed Dataset
Authors: Lu Junkai
Published: April 2024

The traditional method of fire detection is based on the data collected by sensors to detect the changes in environmental factors such as temperature and smoke to judge whether a fire has occurred, which has limitations. In recent years, the deep learning model has become more mature, and the convolution neural network (CNN) has the ability to automatically extract image features with greater advantages than traditional methods. Therefore, this paper studies fire detection based on the deep learning model and compares three models. The specific research is as follows: (1) Collecting datasets and architectural pictures through the network and local agents to make the datasets more versatile with the increasing diversity of data; (2) Three models are selected for comparison, including CNN model, VGG16 model and Mobile Net-V2 model. According to the experiment, the deep learning model can effectively identify and detect the fire area. Among the three selected models, the correct rate of Mobile Net-V2 reaches 99.01%. Compared with the other two models, the convolution neural network has poor accuracy. Although the accuracy of the VGG16 model is close to that of Mobile Net-V2, it consumes more computing resources than Mobile Net-V2. In other words, there are too many internal parameters in the model, so Mobile Net-V2 performs best. Based on the research, it is confirmed that three fire detection models involved in this experiment can identify and monitor the fire area efficiently, which has a great guiding significance for the future application of fire prevention..

The basic structure of proton exchange membrane fuel cell mainly consists of bipolar plates, diffusion layer, catalyst layer and proton exchange membrane, of which the bipolar plates are the most important components. In recent years, composite bipolar plates have become the focus of bipolar plate material research because they combine the advantages of graphite bipolar plates and metal bipolar plates. Therefore, this review explains the development of composite bipolar plates in recent years in a clearer way by sorting out and analysing the pairing of different carbon and resin materials, which will be helpful for bipolar plate development.
Unveiling Momentum Dynamics in Tennis
Authors: Meng Xiangqi , Tian Lei , Zhang Lingchen
Published: April 2024

This study investigates the impact of momentum in tennis competition through a multifaceted approach. We introduce the Momentum Balance Index (MBI), derived via Principal Component Analysis (PCA) from 42 indicators, identifying 13 significant factors influencing player momentum. MBI analysis reveals a strong correlation between peak momentum and score leads, indicative of player condition and winning likelihood. Spearman correlation analysis validates momentum's link to enhanced performance and victory probabilities, challenging randomness in match outcomes. Additionally, an ARIMA-based prediction model, refined through logistic regression, forecasts momentum shifts within matches, offering real-time tactical insights for coaches. Receiver Operating Characteristic (ROC) analysis confirms the model's robust predictive capability, with AUC values exceeding 0.5 across three matches. This comprehensive approach sheds light on momentum dynamics in tennis, providing valuable insights for coaching and strategic decision-making.

Published: April 2024

Traditional PID control methods have been widely used in various industries due to their simplicity and effectiveness in regulating system outputs. However, challenges arise when dealing with systems characterized by non-linearity, delays, or external disturbances, necessitating the development of advanced PID control strategies. This paper presents two enhanced PID control approaches tailored for specific applications: intelligent PID control for temperature regulation of internal combustion engines and radial basis function (RBF) neural network-based PID control of marine motion control. The operating principles and algorithms of both approaches are detailed, and by comparing the enhanced methods with traditional PID control algorithms, their superior performance in terms of accuracy and adaptability is demonstrated, and conclusions are drawn regarding the effectiveness and suitability of each approach for their respective applications.

Published: April 2024

The hypertrophy and relaxation of tongues easily leads to patients’ airway obstruction during sleep, which will cause obstructive sleep apnea hypopnea syndrome (OSAHS). Therefore, studying biomechanical properties of tongues with constitutive relation to obtain related parameters is important. In this paper, applicability study is performed to specify the tongues’ mechanical properties (TMP) based on the Mooney-Rivlin hyperelastic model. Firstly, the research on uniaxial stretching vitro experiments of pig tongues was carried out; then, the material parameters of the proposed model were determined with reference to the experiments results; finally, the advantages and disadvantages of the model to detail the TMP were discussed respectively. The results showed that the Mooney-Rivlin hyperelastic model has a simple structure, which reflects the TMP well while appearance of large deformation but fails to reflect the TMP while the strain is small in linear segment, but that of the toe segment is in contrast to the linear segment.

Published: April 2024

Starter performance tester requires high precision and fast speed with a complex nonlinear structure and strong interference. The traditional PID controller always brings the bad effect with larger current and torque shocks. The complex intelligent algorithm is difficult to be realized in practical engineering for its trouble of parameter tuning. A new PID neural network(PIDNN) controller is designed which integrated the advantages of PID and intelligent controller. PIDNN has simple structure as PID and self-learning ability as NN to optimize parameters. The experiments verified the precision and efficiency of the test system.

LA ETERNA LUCHA ENTRE LA VIDA Y LA MUERTE EN EL CORTOMETRAJE CALVARIO, TOCATA Y FUGA DE UN ATAÚD DEL REALIZADOR SERGIO HERNÁNDEZ
Authors: Betancor Martel Orlando
Published: April 2024

Esta original producción, repleta de humor negro, fue realizada por el cineasta canario Sergio Hernández en el año 1988. Este cortometraje narra las vicisitudes de un ataúd en su camino desde el velatorio hasta su destino final en la necrópolis, un lugar al que no llegará nunca. En este interesante trabajo visual, este realizador aporta su personal percepción sobre la transitoriedad de las glorias humanas frente a las tenebrosas sombras de la muerte. Además, esta cinta, centrada en la realidad de una familia de escasos recursos que vive en las Islas a mediados del siglo pasado, nos ofrece una imagen del Archipiélago bastante alejada de la visión idílica y mítica del Jardín de Las Hespérides.
