Los entramados socioeconómicos solidarios como una herramienta para la soberanía alimentaria
Authors: Matonte Silva Cecilia 
Published: December 2024

Este trabalho surge da análise da aliança sociotécnica (THOMAS, 2008) que compõe a Cooperativa Molino Santa Rosa, no Uruguai. Seus resultados provêm da pesquisa realizada para a Dissertação de Mestrado em Economia Social da Universidade Nacional de General Sarmiento, da Argentina, realizada em 2017. Apresenta-se como continuidade à análise e identificação dos fundamentos que dão sustentação a um enfoque sobre entramados socioeconômicos solidários (MATONTE, 2017), que por sua vez visa superar um olhar atomizado dos empreendimentos econômicos que fazem parte do campo da economia social e solidária (ESS). A relação particular entre as formas de propriedade, poder e saber dos entramados, juntamente com as categorias, territórios e produção dos comuns, faz com que as maneiras de analisar as redes de produção, circulação e consumo de alimentos, na região metropolitana de Montevidéu, apresente desafios particulares para o campo da Economia Social e Solidária. As novas abordagens foram construídas a partir do trabalho desenvolvido com as organizações agroalimentares que integram a Economia Social e Solidária, às quais se vincula a Área de Estudos Cooperativos da Universidad de la República (Uruguai) e estão integradas para análise na investigação em curso no âmbito da tese de doutoramento. As conclusões constituem uma possibilidade de traçar linhas de continuidade entre as teses de mestrado e doutorado, ao mesmo tempo em que aprofundam elementos teóricos e metodológicos necessários para compreender as parcelas agroalimentares na atualidade.
Orality in War Novels: Different Aspects of Swear Words in Henri Barbusse’s and Ahmadou Kourouma’s works
Authors: Kotowska-Miziniak Joanna 
Published: December 2024

The paper proposes to address, from a comparative perspective, the question of orality in two war novels: Henri Barbusse's autobiographical Le Feu (1916) and Ahmadou Kourouma’s fiction Allah n’est pas obligé (2000). In spite of a temporal distance, a generic framework and a narrative structure that separates the two novels, they both present one major common feature which is the concern to describe the martial experiences – real or imagined – in a direct and personal way, which finds its expression at the lexical level. Although Barbusse’s First World War soldiers do not use the same vocabulary as Kourouma’s child soldiers who took part in the fighting in Liberia and Sierra Leone in the 1990s, their language is characterized by the same abusive use of swear words. Apart from its primary function as an instrument of emotional liberation through an instantaneous cathartic discharge, “soldier’s talk” also plays the role of a communication tool that ensures integration within a community. Leaving aside its linguistic, geographical or historical particularities, the language of combatants from different countries crosses borders and acquires a universal dimension, as the bearer of the collective memory of the tumultuous twentieth century.

Published: December 2024

The rainbow connection number of a graph G denoted by rc(G) is the minimum number of colors used to color the edges in G, such that every pair of vertices is connected by a path with all different colors. In 2008, Chartrand et al. first introduced the concept of rainbow connection numbers. They introduced it as an edge coloring on a graph that refers to the path of each pair of vertices. An octopus graph, with m legs denoted by Om, is a graph constructed from a fan graph Fm and a star graph Sm. The graphs studied in this article are two classes of octopus iteration graphs, namely the octopus chain graph and the octopus ladder graph. The octopus chain graph, denoted by O2(n) is a graph constructed from n copies of O2 and connecting one leg of the i-th copy to the (i+1)-th copy, for every I = 1,2,..., n-1. The octopus ladder graph, denoted by O2'(n) is a graph constructed from graph O2(n) by connecting one of vertex of degree two of the i-th copy to the (i+1)-th copy. In this research, we determine the rainbow connection number of the octopus chain graphs O2(n) and the octopus ladder graphs O2'(n). We obtain that rc(O2(n))=3n, for n >= 1 and rc(O2'(n))=3n-1, for n >= 2.Keywords: classes of octopus iteration graphs; octopus chain graph; octopus ladder graph; rainbow connection number.

Published: December 2024

This research investigates the application of optimal control in the Susceptible, Exposed, Addicted, Recovery, Quit (SEA_1 A_2 RQ) model to address social media addiction. The primary objective is to develop an effective control strategy to reduce the prevalence of social media addiction. The methodology employs Pontryagin's maximum principle to formulate the optimal control problem, incorporating two time-dependent control variables: control (u_1) and treatment (u_2). The optimal control model is numerically simulated using the 4th-order Runge-Kutta method. Comparative analysis of the simulation results, with and without control, demonstrates significant differences in all population groups after four years. The findings reveal that implementing control (u_1) and treatment (u_2) markedly decreases the number of individuals addicted to social media, highlighting the efficacy of the proposed strategy in mitigating social media addiction.Keywords: optimal control; social media addiction model; Pontryagin maximum principle.

Risk-Targeted Design Spectra for Uniform Risk Seismic Design
Authors: Wang Cong , Lu Da-Gang 
Published: December 2024

Abstract
The uniform hazard response spectrum only considers the seismic hazard of a site, without taking into account the seismic fragility of the structure. As a result, structures designed based on this spectrum may exhibit varying levels of collapse risk under earthquakes in different regions. To this end, first, various cases are employed to determine a first-order approximation of the seismic hazard function H(x), followed by a validation of its rationality. Subsequently, with the objective of achieving uniform collapse risk, considering both seismic hazard and structural fragility, single anchor point, double anchor points, and multiple anchor points methods are proposed to construct the risk-targeted seismic design spectra for frequent earthquake (FE), design basis earthquake (DBE), maximum considered earthquake (MCE), and very rare earthquake (VRE). Furthermore, a comprehensive study is conducted to analyze the risk-targeted seismic design spectra corresponding to different seismic design levels, site classes, and characteristic periods constructed using the multiple anchor points method. In addition, a comparative analysis is conducted on the risk-targeted seismic design spectra constructed using different methods. The study indicates that determining H(x) based on DBE and VRE is reasonable, and the relative difference between the risk-targeted ground motion (RTGM) derived from this case and the RTGM obtained by determining H(x) based on probabilistic seismic hazard analysis is within 4%. The risk-targeted seismic design spectra constructed using three different methods show overall similarity. The single anchor point method offers simplicity in calculations and ensures that the uniform risk seismic design spectrum aligns with the uniform hazard seismic design spectrum in terms of spectral shape. Although the multiple anchor points method involves increased computational effort, it allows for the consideration of seismic hazard at multiple periods.

Published: December 2024

Abstract
This study reveals the seismic signature of the 1973 Chilean coup d’état by analyzing historical paper seismograms from September 1973. The continuous traces of the seismic activity preceding, during, and after the military coup were recorded by a Teledyne Geotech seismometer installed near (∼2 km) the presidential palace La Moneda. Our analysis revealed that distinct seismic patterns corresponded to specific societal activities, such as the morning commute and nighttime quietness. The seismic records captured the upheaval caused by the coup, including the military intervention, the bombing of La Moneda palace, and the subsequent imposition of a national curfew. The latter led to a significant reduction in anthropogenic noise making it easier to detect seismic events with enhanced clarity. To reconstruct the events of September 1973, we combined the seismic data with the historical archives of the Museo de la Memoria y los Derechos Humanos (Museum of Memory and Human Rights Foundation). This research offers a unique perspective on the recent history of Chile. It also highlights the importance of seismic and scientific records as elements of cultural heritage worthy of preservation and recognition. In addition, it underlines the close link between Chile’s seismological characteristics and the profound influence they have had on the shaping of the country’s identity serving as an invaluable source of inspiration for artistic representations of natural hazards and disasters. Finally, the article emphasizes the imperative of preserving historical scientific records, not only as invaluable resources for advancing scientific understanding, but also as foundational elements for fostering transdisciplinary collaborations. The safeguarding of these records facilitates the interplay between science and art, creating new pathways for the dissemination of complex scientific knowledge, while inspiring creative expressions that engage with and reflect on Chile’s cultural and natural history.

Published: December 2024

Objective: To use SMOTE to enhance class balance and compare the performance of different classification methods before and after applying SMOTE.
Methods: The study used a dataset from Kaggle. Consisted of several health-related features linked to obesity prediction. Checking for class imbalance within the dataset affected initial model performance. SMOTE was applied to synthetically increase the representation of minority classes, reducing the class imbalance. It was conducted in two stages: 1. Training and testing the classification algorithms before applying SMOTE. 2. Training and testing the same models after applying SMOTE to enhance class balance. The performance of all models was evaluated based on metrics before and after the SMOTE application.
Results: Models Logistic Regression and Naive Bayes struggled with low sensitivity and specificity, and KNN (k=5) showed poor specificity. Significant improvements were observed across all models after applying SMOTE. Logistic Regression, despite a decrease in accuracy(-8.8), sensitivity and specificity increased substantially(+56.7%), with balanced accuracy improving(+16.6%). Naive Bayes saw a modest accuracy increase(+2.3%), with sensitivity and specificity improving(+47.9%). The KNN classifier exhibited a transformative enhancement with sensitivity and specificity increasing(+96.0%) and balanced accuracy(+28.3%). Deep Learning showed a significant increase in sensitivity (+69.8%), balanced accuracy (+29.4%), and an improvement in precision and F1-score despite a slight decrease in specificity(-10.9%).
Conclusion: The results demonstrate that while there might be slight trade-offs, the overall improvements in key metrics such as sensitivity, specificity, balanced accuracy, precision, and F1-score affirm the utility of SMOTE in enhancing model performance for imbalanced datasets
O SERVIÇO DE PROTEÇÃO E ATENDIMENTO INTEGRAL À FAMÍLIA: PAIF E A PROTEÇÃO SOCIAL NO CRAS KARAJÁ I DE PALMAS-TO.
Authors: Sousa Cunha Fátima Raulina de , Dos Santos Rosemeire 
Published: December 2024

RESUMO:
O debate contemporâneo a cerca da centralidade da família nas políticas de proteção social tem ocorrido de forma bastante tensionada, marcada por contradições em termos da garantia da proteção social. As famílias longe de terem sido esvaziadas de suas funções sociais, desempenham o papel de protetora de seus membros. As famílias, incorporadas nas políticas de proteção social e naturalizadas enquanto instituição central de proteção social no contexto de crise do capitalismo, marcado pela acelerada acentuação do neoliberalismo, encontram-se fragilizadas pelos processos e pelas mudanças que marcam a realidade brasileira, paradoxalmente, ampliam-se suas responsabilidades como mecanismo de proteção social. Essa responsabilização tem sido altamente naturalizada, o que reflete no direcionamento do trabalho social com famílias, e condiciona a execução do Serviço de Proteção e Atendimento Integral à Família (PAIF). Diante dessas contradições, esse trabalho tem como objetivo discutir o familismo presente nas políticas sociais e os seus rebatimentos na garantia da proteção social às famílias no PAIF. Para tanto serão utilizadas a revisão integrativa de literatura, pesquisa participante, pesquisa documental e entrevista com grupo focal.

Abstract

Zika virus (ZIKV) poses a significant threat due to its association with severe neurological complications, particularly during pregnancy. Although viruses exhibit tropism for neural cells, including astrocytes, the role of these cells in controlling ZIKV replication remains unclear. In this study, we demonstrated that ZIKV induces caspase-1 activation in primary astrocytes despite the absence of classical signs of inflammasome activation. Caspase-1/11-/- astrocytes exhibit heightened permissiveness to viral replication, accompanied by overactivation of glycolytic metabolism. Inhibition of glycolysis reversed the susceptibility of caspase-1/11-/- astrocytes to ZIKV infection. Protein network analysis revealed mTORC as a link between proteins involved in glycolysis and caspase-1, and mTORC inhibition also suppressed viral replication. Furthermore, we found that the impact of caspase-1/11 on astrocytes depends on the regulation of pyruvate transport to mitochondria for viral replication. Overall, our findings elucidate a caspase-1/11-dependent microbicidal mechanism in astrocytes that involves the mTORC/glycolytic pathway/pyruvate axis, providing insights into potential therapeutic targets for ZIKV infection.

Abstract

Purpose
The purpose was to determine the fetal liver blood flow and identify whether diabetes mellitus complicates the ductus venosus (DV) shunt fraction and adverse outcomes in pregnancies.
Methods
We conducted a prospective longitudinal observational study including 188 pregnant women: group I – patients with pregestational DM (PGDM, n = 86), group II – patients with gestational DM (GDM, n = 44), group III - control (n = 58). Patients included in the study underwent ultrasound examination at 30+ 0 − 41+ 3 weeks of pregnancy. We evaluated volumetric blood flow adjusted to EFW (Q, ml/min/kg) for umbilical vein, DV, left and main portal vein. Relative risk was calculated for adverse pregnancy outcomes.
Results
There was a redistribution of volumetric blood flow to the fetal liver by decreasing the DV shunt fraction in PGDM pregnancies. These changes were characterized by an increase in left portal and total liver volumetric blood flow compared with GDM and control groups (p < 0.001). In some PGDM patients, the DV shunt fraction was pathologically reduced. A reduction in DV shunt fraction ≤16.5% was associated with an increased relative risk of preterm delivery (3.61), LGA-birth (1.64), neonatal adiposity (1.53), fetal hypoxia (3.47), emergency cesarean section (1.93), and neonatal intensive care unit stay more than 5 days (1.78).
Conclusion
Decreased DV shunt fraction reflects changes in fetal hemodynamics and may be an important marker of fetal adversity. A decrease in DV shunt fraction of less than 16.5% is associated with an increased risk of adverse perinatal outcomes in patients with PGDM.
