Sociedad, Estado y mercado en la era post-pandémica: imaginando un nuevo pacto social para Ecuador y México
Authors: Enríquez Pérez Isaac , García Álvarez Santiago
Published: March 2024

Escrito al unísono de la crisis epidemiológica global, el presente artículo tiene como objetivo abrir un debate público y proponer, desde una perspectiva crítica y normativa, un conjunto de alternativas de cambio social y transformación económica con miras a enfrentar —desde el mundo subdesarrollado— los múltiples impactos de la crisis disruptiva de la pandemia de COVID-19. Aunque no suficientes del todo estas propuestas, consideramos que responden a la urgencia de pensar en tiempo real ante los desafíos que impone una pandemia que condensa una crisis sistémica y ecosocietal de amplias proporciones entrelazada con la misma crisis global del capitalismo y con el actual colapso civilizatorio. Un nuevo pacto social amerita recuperar debates teóricos relacionados con los problemas públicos y la toma de decisiones, así como desplegar la imaginación creadora y la voluntad política para ampliar la posibilidad de forjar acuerdos sociales diversos, suficientes, realizables y no maximalistas.

The goal of this investigation was to study the influence of different values of Temperature-Humidity index (THI) on the duration of lying down and feed consumption, productivity, and heat production by dairy cows in two variants of feedlots (with and without shelters). The study was conducted from February 2007 to early August 2021 in the central part of Ukraine (Kyiv region) in different periods of THI. This index was divided into three categories: 1) 66–71: normal (14 days); 2) 72–79: alert (11 days); 3) >80: dangerous (9 days). Two variants of feedlots were selected: Open feedlot with shelters and open feedlot without shelters. The largest increase in values of THI affecting the cows was observed in open feedlots without shelters. There, in alert and danger periods duration of feed consumption decreased by 8.0 and 23.1 min, lying down by 17 and 38 min, productivity by 2.3 kg (or 8.77%) and 3.6 kg (or 13.74%), energy consumption by 4.7 and 9.6 MJ, respectively, in comparison to normal period.

Authors: Mendoza-Estela Jierson E.
Published: March 2024

Ovariohysterectomy through the linea alba is one of the most applied surgical techniques in companion animals; however, this technique presents frequent postoperative complications. The present study aims to demonstrate the feasibility and advantages of ovariohysterectomy in cats through the lateral approach. In total, 30 clinically healthy cats weighing 2.9 ± 0.9 kg body weight, 1.5- 4 years old and of various breeds, were operated on. In the preanesthetic medication, xylazine hydrochloride (0.1 mg/kg) and ketamine hydrochloride (0.5 mg/kg) were applied IM, anesthesia was done with diazepam (0.5 mg/kg) and ketamine hydrochloride (10 mg/kg). IV route, and maintenance with boluses of ketamine hydrochloride (0.5 mg/kg) based on dose-response. A single dose of amoxicillin (10 mg/kg) was applied IM at the end of surgery. The time of the surgical intervention was 19.8 ± 2.5 minutes and for wound healing it was 6.9 ± 1.2 days. Two patients 6.7% (2/30) presented inflammation and local infection. It is concluded that ovariohysterectomy through a lateral approach in cats is a viable alternative due to its ease of execution, reduced healing time and minimal presentation of postoperative complications.

Published: March 2024

Seis modelos matemáticos no lineales fueron evaluados (Wood, Wood modificado, Cuadrático, Sikka, Singh-Gopal y Cobby) para determinar su capacidad de ajuste para describir la curva de lactancia en yeguas. La modelación se realizó a partir de 197 registros de producción de leche de yeguas entre los 2 y 190 días de lactancia. Los modelos fueron ajustados empleando algoritmos de regresión no lineal y se evaluaron a través de los siguientes criterios de comparación: MAE (Error absoluto medio), MAPE (Error porcentual absoluto medio), RMSE (Raíz del error cuadrático medio), AIC (Criterio de información de Akaike), BIC (Criterio de información bayesiano) y análisis de residuales. Los modelos Wood, Singh-Gopal, Wood modificado y Sikka predijeron que la máxima producción de leche varía entre 10 y 13 kg/día, la cual ocurre entre los 30 y 42 días posparto. De acuerdo con los criterios evaluados, los modelos Wood y Singh-Gopal presentaron el mejor ajuste y se mostraron adecuados para modelar las curvas de lactancia en équidos.

Authors: Pérez Gómez Carla Amanda , Torres Mariett , Pozo Karla , Echeverry Berrío Diana
Published: March 2024

Los microplásticos se generan por la fragmentación del plástico que ingresa a los océanos y es consumido accidentalmente por diversas especies que se encuentran en la cadena trófica. Los otáridos son considerados como bioindicadores de la presencia de micropartículas en el ambiente; sin embargo, se desconoce el nivel de afectación en la zona costera de la región del Bio-bío, Chile. El objetivo del presente trabajo fue evaluar la presencia de este polímero en heces de lobos marinos (Otaria flavescens), en el sector ‘La Poza’, comuna de Talcahuano, región del Bio-bío. Se tomaron muestras de heces que fueron liofilizadas, digeridas y posteriormente filtradas para identificar microplásticos. Se encontraron microfibras de varios colores, con predominio del color negro. Se concluye que los lobos marinos fueron indicadores de circulación de microplásticos en su cadena trófica en la zona de muestreo.

Published: March 2024

La complejidad a partir de la pandemia pone en evidencia limitaciones de la enseñanza superior y acelera replanteos sobre las prácticas y su transformación. La evaluación de los aprendizajes se vuelve central pues los procesos de acreditación presionan sobre las prácticas mismas. Frente al desafío por adaptar la evaluación al nuevo contexto, en un marco inclusivo y de democratización de saberes, las y los docentes se reúnen a compartir experiencias e instrumentos, cuestionando evaluaciones propias y adaptando y adoptando soluciones de colegas. Una propuesta de talleres virtuales desarrollada entre 2020 y 2022 alentó el análisis, producción, coevaluación y reflexión sobre prácticas evaluativas de manera colaborativa en seis universidades nacionales de Argentina. Los talleres promovieron propuestas enriquecidas entre pares. Se revisaron los instrumentos desde la pertinencia con los propósitos, la claridad en la formulación de consignas, los desafíos cognitivos demandados y el acuerdo a construir en torno a criterios de valoración. El monitoreo ofrecido por el asesoramiento pedagógico permitió cuestionar lo dado, sosegar la inmediatez producida por la criticidad del actuar y promover mejoras a lo largo de los talleres. Las tecnologías enriquecen las propuestas evaluativas para que tengan sentido inclusivo y de democratización del conocimiento.
Multisensory Approach in Education
Authors: Georgieva Zhana
Published: March 2024

Children learn by receiving information through their senses. Multisensory learning involves the use of the visual, auditory, kinetic and tactile channels to support the development of learning and mental processes. It should be understood as a methodology, as a specific vision of learning technology, which is based on the use and stimulation of the various sensory systems not separately with a view to their self-directed development, but in parallel, jointly, on the principle of interchangeability, compensation, cooperation. The article examines the essence of the multisensory teaching approach. The main emphasis is placed on the sensory systems that serve the person to perceive information coming from the external environment. The more senses we include in the learning process, the more likely children are to remember and absorb what we teach them. Learning comes naturally when they have the opportunity to use as many senses as possible.

Published: March 2024

The fishing cat (Prionailurus viverrinus) is a protected animal. Currently, the population in nature is declining due to over-fishing and changes in environmental quality. The existence of this fishing cat is an interesting finding that must be immediately studied at the morphological and genetic levels for certainty of its species. This study aimed to identify fishing cat from Wonorejo Mangroves, based on morphology and Cyt b genes analysis. The results of Cyt b identification obtained a DNA sequence length of 398 bp with a similarity value of the five Prionailurus sp. samples between 96.75 to 98.97%. The identification using molecular data consisted of five variations of nucleotide bases, and the average value of the genetic distance with the ingroup was 1.0%., The Cyt b DNA markers analysis succesfully identified fishing cat from Wonorejo Mangroves as Prionailurus viverrinus.
Sentidos sobre o adoecer por câncer no filme Aquarius
Authors: Scorsolini-Comin Fabio , Rossato Lucas
Published: March 2024

Resumo A linguagem fílmica constitui um importante recurso para o ensino-aprendizagem no campo da saúde. Para trabalhar a temática do adoecimento por câncer, diversos filmes têm sido empregados como disparadores de reflexões necessárias à formação de profissionais de saúde capazes de uma atuação mais empática, sensível e humanizada. Para contribuir com esse cenário, o presente estudo teve por objetivo discutir os sentidos sobre o adoecimento pelo câncer a partir da análise do filme Aquarius. Os sentidos predominantes neste filme referem-se ao câncer como uma invasão do corpo sadio e como roubo de algo importante ao sujeito. As temáticas da sexualidade e do protagonismo feminino entrelaçam-se na costura de um filme que metaforiza o câncer em suas múltiplas representações sociais, abrindo espaço para o sentido de potência, rompendo com estereótipos negativos predominantes nas demais linguagens.

ABSTRACT: This study detected Anaplasma marginale in calvesusing blood smears and nested PCR (nPCR) and to compare the results with the clinical signs presented by calves on a dairy farm in the municipality of Castanhal, located northeast of the state Pará (1°07’19.1”S and 47°53’53.0”W), eastern Amazon. To this end, 192 blood samples were collected from 24 animals at 1-20, 21-41 and 42-60 days of age. Blood smears and nPCR with primers for the msp5 gene were performed. The prevalence of A. marginale was 61.5% (118/192) for the blood smear technique and nPCR (msp5). The manifestation of clinical signs of anaplasmosis also increased significantly over the course of the study (P < 0.0001), being lower in animals aged 1-20 days, but increasing among those aged 21-41 and 42-60 days. These signs were characterized by apathy, fever, weight loss, diarrhea, dehydration, and hypochromic mucous membranes. Regarding the evaluation of the diagnostic techniques, no significant difference was observed in the detection of A. marginale between the blood smear and nPCR (P = 0.995), but the agent’s rickets increased on Day 47 (P < 0.01) in both tests, thereby demonstrating a near-linear pattern of increase in rickets over the 60 days, with a consequent decrease in globular volume. This shows that of the 24 animals studied, 21 were infected at some point during the study period. Additionally, there was no significant difference between blood smears and nPCR, probably due to medium and high parasitemia, which were directly related to the clinical signs and decrease in globular volume.

Abstract Currently, the standard non-invasive test for diagnosing Peripheral Arterial Disease is the Ankle-Brachial Index. However, this test becomes unfeasible in a certain population. New evidence proposes the pedal acceleration time, an ultrasound index, as an alternative test. An integrative bibliographic review was carried out between June 3, 2022 and January 8, 2023, to investigate this new index as a tool to assess foot perfusion. Papers published in English, Portuguese, or Spanish between 2012 and 2022 were searched on PubMed, Google Scholar, and Scielo, using the keywords “Peripheral Arterial Disease” AND “Acceleration Time” AND (Pedal OR Plantar). Research that didn’t assess foot perfusion using the methods of interest or did not present human data and also case series or reports were excluded. Seven out of the sixty-six articles identified in the searches were selected for the review, all of which had notable methodological limitations. Pedal acceleration time seems to be able to diagnose and stratify and may reflect prognosis.

Published: March 2024

Resumo Contexto O acesso vascular preferencial para hemodiálise é a fístula arteriovenosa nativa, pois oferece melhores resultados em curto e longo prazo, proporciona menor morbimortalidade e traz vantagens adicionais em relação aos cateteres venosos centrais ou enxertos arteriovenosos. No entanto, a obesidade pode oferecer um desafio adicional proporcionado pela barreira de tecido celular subcutâneo que recobre a superfície da veia a ser puncionada. Objetivos Demonstrar a experiência do serviço com a lipectomia em acessos autólogos em pacientes obesos. Métodos Foram revisados pacientes consecutivos submetidos à lipectomia por impossibilidade ou dificuldade na punção da FAV, motivada pela acentuada profundidade da veia cefálica no antebraço ou braço. Resultados Vinte e dois pacientes foram revisados (15 homens e 7 mulheres), com índice de massa corporal médio de 34 kg/m2 (variação de 28 a 40 kg/m2). A idade média foi de 58,4 anos. O tempo médio entre a confecção do acesso e a lipectomia foi de 45,1 dias, e o tempo da intervenção até a liberação para uso nas sessões de hemodiálise oscilou de 21 a 42 dias, com média de 30,9 dias. A profundidade média pré-operatória da veia cefálica no membro foi de 7,9 mm (variação de 7,0 a 10,0 mm). Isso foi reduzido para uma profundidade média de 4,7 mm (faixa de 3,0 a 6,0 mm) (P = 0,01). O período médio de seguimento dos pacientes foi de 13,2 meses. Houve perda de seguimento em quatro pacientes e quatro óbitos no período não relacionados ao acesso vascular. Conclusões A obesidade não deve ser um fator limitante para a criação de uma FAV nativa, pois a lipectomia é uma alternativa relativamente simples de superficialização, que permite a funcionalidade de fístulas arteriovenosas nativas e profundas em obesos.

Published: March 2024

Resumen: Este trabajo ahonda en las brechas de género presentes en las instituciones de justicia, entendiéndolas críticamente como espacios de disputas de poder y de saber. Cuando aún la tendencia de los estudios existentes en Chile sobre el tema ha sido utilizar metodologías cualitativas, nuestra investigación se vale de estadísticas detalladas para estudiar el caso de la región del Bío-Bío. Esta forma de análisis permite una observación fina, y al mismo tiempo global, de diferentes dimensiones organizacionales que son estructuradas por el género, que no siempre actúan de manera unívoca. Con este propósito, se analiza la proporción de mujeres y hombres profesionales del derecho y del ámbito psicosocial que existen en instituciones de justicia de la región, y además se observa el nivel de ingreso asociado a sus cargos.
Associations and gender differences between OHI-seeking behaviors and eHealth literacy among Chinese university students
Authors: Chen Jie , Tian Hua
Published: March 2024

ABSTRACT Objective: to explore associations and gender differences between OHI-seeking (online health information seeking) behaviors and eHealth (electronic health) literacy among Chinese university students. Methods: Online questionnaires of eHealth literacy scale and OHI-seeking behaviors created in software Wenjunxing were used in this survey. Chi-squared tests, t-test, and Pearson correlation analysis were performed using SPSS for data analysis. Results: Among 5,383 participants, 72.4% were girls, 77.5% lived in rural areas, 51.2% majored in liberal arts, 76.6% with low education parents. The average C-eHEALS scores of boys and girls were 26.53 ± 5.861 and 26.84 ± 5.816, respectively, with no significant difference (P = 0.084). The top three OHI-seeking behaviors for boys and girls, as well as for the C-eHEALS low and high groups, were “finding information about physical exercises” “reading or sharing health information via social media” “finding information about nutrition and diet”, all of which had significant gender and eHealth literacy differences. Conclusions: Gender and eHealth literacy differences should be focused for intervention when developing and implementing eHealth intervention training for parents and adolescents in schools and communities.
Golf as an Innovation in the Teaching of Finance: Report on a Pioneering Experience
Authors: Mendes-da-Silva Wesley
Published: March 2024

ABSTRACT Objective to analyze the possibility of using golf as a metaphor for teaching finance. Study reports on a pilot experience of teaching finance using golf as a metaphor.Golf can be a means of promoting the engagement of finance students. Theoretical framework: a normative and positive economic decision theory is used as a framework. Sports can be a means of engaging students in finance education programs. Golf, in particular, can fulfill this role and serve as a powerful tool for building and maintaining social networks relevant to high-level professionals. Methods: thirty undergraduate students voluntarily participated in a pilot teaching program over five days. The program included sessions (in the field) on the fundamentals of golf and financial decisions, and students looked for synergies between these two domains. Participants showed a high level of interest in both the sports practice sessions and the finance activities. Results: the results suggest that psychological errors common to golf and financial behavior-for example, overoptimism, overconfidence, and emotional judgments-can be diagnosed and addressed through sports practice. In addition, the participants’ self-assessment indicates the possibility that the program can induce behaviors in line with the corporate environment. Conclusions: Despite golf’s contribution to the teaching of business subjects, it is still absent from formal curricula.

Authors: Mendes-da-Silva Wesley
Published: March 2024

RESUMO Objetivo: analisar a possibilidade do emprego do golfe como metáfora para o ensino de finanças. Este estudo relata uma experiência piloto de ensino de finanças com o emprego da prática do golfe como metáfora. O golfe pode ser um meio para promover o engajamento de estudantes de finanças. Marco teórico: teoria normativa e positiva da decisão econômica. A prática esportiva pode ser um meio de engajar estudantes em programas de ensino de finanças. O golfe, em especial, pode desempenhar esse papel, além de constituir uma poderosa ferramenta de construção e manutenção de redes sociais relevantes ao profissional de alto nível. Métodos: trinta estudantes, em nível de graduação, voluntariamente inscritos participaram do programa piloto de ensino ao longo de cinco dias, com sessões (em campo) de fundamentos do golfe e de decisões financeiras, buscando sinergias entre esses dois domínios. Constata-se o interesse elevado dos participantes tanto nas sessões de prática esportiva como nas atividades de finanças. Resultados: os resultados sugerem que erros psicológicos comuns ao golfe e ao comportamento financeiro, e.g., excesso de otimismo, excesso de confiança e julgamentos emocionais, podem ser diagnosticados e endereçados por meio da prática esportiva. Em adição, a autoavaliação realizada pelos participantes sugere a possibilidade de que o programa possa induzir comportamentos alinhados com o ambiente corporativo. Conclusões: em que pese a contribuição do golfe para o ensino de disciplinas da área de negócios, ele ainda é ausente dos currículos formais.
The Leadership is Leaving, Now What? Change Management in a Science Park
Authors: Costa Isabel de Sá Affonso da , Tavares Elaine Maria
Published: March 2024

ABSTRACT This teaching case describes the organizational change process of the Federal University of Rio de Janeiro Science Park (PTEC-UFRJ), an organization that plays a leading role in the innovation ecosystem of both the university and its surrounding state. The change process began in 2019, rooted on the leadership’s view that the Park’s economic sustainability depends on strategic redirection and transformation of employees’ attitudes and behavior, along with the redesign of PTEC-UFRJ’s internal processes. However, PTEC-UFRJ has the peculiarity of having its leadership appointed by the University Dean’s Office. In this context, management initiatives directed to supporting the change process are fundamental to secure its achievements and ensure its continuity. The case describes the decisions and actions took by PTEC-UFRJ’s executive director in order to guide the strategic change in the Park and the challenges faced. In view of the results and objectives already achieved, the most important point is to discuss PTEC-UFRJ’s future perspectives, the role of leadership and organizational policies, and practices that guarantee the sustainability of the organizational change

Published: March 2024

ABSTRACT Objective: To describe the current state of the art in the therapeutic administration of botulinum toxin with indications, efficacy, and safety profile for children and adolescents with cerebral palsy. Data source: An integrative review was conducted. The MEDLINE/PubMed database was searched twice within the last decade using distinct terms, and only studies written in the English language were included. The study population was limited to those aged 0–18 years. Articles that were duplicates or lacked sufficient methodology information were excluded. Data synthesis: We found 256 articles, of which 105 were included. Among the included studies, most were conducted in developed countries. Botulinum toxin demonstrated good safety and efficacy in reducing spasticity, particularly when administered by a multidisciplinary rehabilitation team. It is primarily utilized to improve gait and upper limb function, facilitate hygiene care, reduce pain, prevent musculoskeletal deformities, and even decrease sialorrhea in patients without a functional prognosis for walking. Conclusions: The administration of botulinum toxin is safe and efficacious, especially when combined with a multi-professional rehabilitation team approach, which increases the probability of functional improvement. It can also be beneficial for patients with significant functional impairments to help with daily care tasks, such as hygiene, dressing, and reducing sialorrhea. Pediatricians must be familiar with this treatment and its indications to attend to and refer patients promptly when necessary, and to exploit their neuroplasticity. Further research on this topic is required in developing countries.

ABSTRACT Objective: The current study aimed to translate the Hammersmith Infant Neurological Examination (HINE) into Brazilian Portuguese and analyze the reliability of the translated version for a population of Brazilian infants. Methods: This was a methodological study, approved by the Ethics Committee, carried out between June 2020 and May 2021. HINE is a standardized clinical neurological examination used for the early detection of cerebral palsy. The quantitative section, “neurological examination”, contains 26 items scored from 0 to 3 points, divided into five categories: cranial nerve function, posture, movements, muscle tone and reflexes, and reactions. The HINE translation followed four steps: translation, synthesis, back-translation, and evaluation by an expert committee. To verify the reliability of the HINE-Br (Portuguese-Brazil version) two independent examiners evaluated 43 infants, between 3 and 22 months of age. Internal consistency was verified by Cronbach’s Alpha coefficient and interrater reliability by the intraclass correlation coefficient (ICC). Results: The translated version was similar to the original version and a few semantic and idiomatic adjustments were necessary. Appropriate internal consistency (Alpha=0.91) was found for the 26 items of the HINE-Br, as well as strong interrater reliability for the total score (ICC2.1=0.95), and also for the five categories (ICC2.1=0.83–0.95). Conclusions: The HINE-Br presents adequate rates of internal consistency and interrater reliability, and can be used for the evaluation of children at risk for cerebral palsy, between 3 and 24 months of age, by pediatricians and pediatric physical therapists.
Polyphenol analysis in human milk by a rapid, cost-effective, and accurate micromethod: translational development
Authors: Cortez Mariela Valentina , Scotta Ana Veronica , Miranda Agustín Ramiro , Soria Elio Andrés
Published: March 2024

ABSTRACT Objective: To develop a rapid method for analysing polyphenols, which are potentially active antioxidants against neonatal oxidative stress, from small human milk (HM) volumes. Methods: Acid and alkaline extractions were compared using two dyes: Folin-Ciocalteu and Fast Blue BB. Linearity, sensitivity, recovery percentage, polyphenol content, precision, and stability were assessed in 14 HM samples and compared using the Kruskal-Wallis H test (p<0.05). The best technique was applied to 284 HM samples to determine their polyphenolic content and its association with maternal diet by multifactorial linear regression. Results: Acidic extraction successfully recovered the gallic acid reference standard, whereas alkaline extraction overestimated it. Calibration curves for all methods were linear (R2>0.96) up to 500 mg/L. All bicarbonate-based Folin-Ciocalteu methods assayed were stable and repeatable, whereas Fast Blue BB-based variants were not. HM polyphenols (mean=94.68 mg/L) positively correlated to the dietary intake of hydroxycinnamic acids, the most consumed polyphenolic family in this population. Conclusions: A bicarbonate-based Folin-Ciocalteu micromethod allowed the accurate determination of polyphenols in HM, which might be useful for translational research settings and HM banks.

Published: March 2024

ABSTRACT Purpose To seek evidence of validity and reliability for the Compressed Speech Test with Figures. Methods The study was subdivided into three stages: construct validation, criteria and reliability. All participants were aged between 6:00 and 8:11. For the construct, Compressed Speech with Figures and the gold standard Adapted Compressed Speech test were applied to children with typical phonological development. For criterion analysis, Compressed Speech with Figures was applied in two groups, with typical (G1) and atypical (G2) phonological development. Finally, the application protocols underwent analysis by two Speech Therapists, with experience in the area of Central Auditory Processing, seeking to obtain an inter-evaluator reliability analysis. Results The correlation test indicated an almost perfect construct (correlation 0.843 for the right ear and 0.823 for the left ear). In the criterion analysis, it was noticed that both groups presented satisfactory results (G1 = 99.6 to 100%; G2 = 96 to 96.5%). The reliability analysis demonstrated that the protocol is easy to analyze, as both professionals presented unanimous responses. Conclusion It was possible to obtain evidence of validity and reliability for the Compressed Speech with Figures instrument. The construct analysis showed that the instrument measures the same variable as the gold standard test, with an almost perfect correlation. In the criterion analysis, both groups presented similar performance, demonstrating that the instrument does not seem to differentiate populations with and without mild phonological disorder. The inter-evaluator reliability analysis demonstrated that the protocol is easy to analyze and score.

Published: March 2024

Resumo O artigo realiza uma investigação comparada sobre as instituições políticas das 18 maiores democracias em população e Portugal. Em seguida, avalia o papel dessas configurações institucionais na estabilidade governamental. São propostas duas visões sobre os sistemas de governo: (a) a tradicional, presidencialismo, parlamentarismo ou semipresidencialismo; e (b) uma transversal, focada na programação constitucional contra crises políticas, classificada como rígida, resiliente ou flexível. A pesquisa recorre a modelos de regressão logística e a dados em painel. É proposta a inferência de que programações constitucionais flexíveis (no parlamentarismo e no semipresidencialismo) apresentam menor estabilidade governamental. Os resultados são submetidos a uma análise comparativa que valida a interpretação e destaca as características institucionais cuja intencionalidade é a produção de estabilidade governamental.
Os negros nas faculdades de Direito do Brasil no século XIX: exclusão, preconceito e apagamento
Authors: Pesso Ariel Engel
Published: March 2024

Resumo No século XIX, existiram duas faculdades de Direito no Brasil, uma em São Paulo e outra em Olinda (posteriormente transferida para o Recife), ambas fundadas em 1827. O objetivo do presente artigo é analisar como o negro se inseria em tais faculdades no período imperial, sob a ótica de três aspectos diferentes, mas complementares: exclusão, preconceito e apagamento. Para tanto, faremos uso de fontes primárias e secundárias, com o escopo de resgatar a memória de pessoas negras que fizeram parte dessas instituições ou que nelas tentaram ingressar, mas não conseguiram.

Resumo: Mensuramos a instabilidade do poder Executivo no Brasil olhando para a taxa de rotatividade ministerial. Desenvolvemos um modelo com doze covariáveis para verificar se elas impactam na demissão dos ministros e, portanto, na instabilidade política dos diferentes governos entre 1946 e 1964. Essas variáveis se referem ao perfil dos ministros, a fatores institucionais e conjunturais, tanto políticos quanto econômicos. Os resultados obtidos através do modelo de riscos proporcionais de Cox mostraram que dois fatores foram preponderantes para explicar a configuração política desse período: o aumento do número efetivo de partidos na Câmara dos Deputados e a constante variação na quantidade de partidos representados no gabinete dada a necessidade de acomodar aliados. Variáveis políticas ligadas à consolidação do regime, como a idade de existência da democracia, ou econômicas, como o aumento do PIB e a diminuição das taxas de inflação, não foram significativas.

Consumer credit services offered by electronic commerce platforms provide customers with convenient loan access during shopping and have the potential to stimulate sales. To understand the causal impact of credit lines on spending, previous studies have employed causal estimators, (e.g., direct regression (DR), inverse propensity weighting (IPW), and double machine learning (DML)) to estimate the treatment effect. However, these estimators do not treat the spending of each individual as a distribution that can capture the range and pattern of amounts spent across different orders. By disregarding the outcome as a distribution, valuable insights embedded within the outcome distribution might be overlooked. This paper thus develops distribution valued estimators which extend from existing real valued DR, IPW, and DML estimators within Rubin’s causal framework. We establish their consistency and apply them to a real dataset from a large electronic commerce platform. Our findings reveal that credit lines generally have a positive impact on spending across all quantiles, but consumers would allocate more to luxuries (higher quantiles) than necessities (lower quantiles) as credit lines increase.
Root Cause Analysis in Microservice Using Neural Granger Causal Discovery

Published: March 2024

In recent years, microservices have gained widespread adoption in IT operations due to their scalability, maintenance, and flexibility. However, it becomes challenging for site reliability engineers (SREs) to pinpoint the root cause due to the complex relationship in microservices when facing system malfunctions. Previous research employed structure learning methods (e.g., PC-algorithm) to establish causal relationships and derive root causes from causal graphs. Nevertheless, they ignored the temporal order of time series data and failed to leverage the rich information inherent in the temporal relationships. For instance, in cases where there is a sudden spike in CPU utilization, it can lead to an increase in latency for other microservices. However, in this scenario, the anomaly in CPU utilization occurs before the latency increases, rather than simultaneously. As a result, the PC-algorithm fails to capture such characteristics. To address these challenges, we propose RUN, a novel approach for root cause analysis using neural Granger causal discovery with contrastive learning. RUN enhances the backbone encoder by integrating contextual information from time series and leverages a time series forecasting model to conduct neural Granger causal discovery. In addition, RUN incorporates Pagerank with a personalization vector to efficiently recommend the top-k root causes. Extensive experiments conducted on the synthetic and real-world microservice-based datasets demonstrate that RUN noticeably outperforms the state-of-the-art root cause analysis methods. Moreover, we provide an analysis scenario for the sock-shop case to showcase the practicality and efficacy of RUN in microservice-based applications.

One of the challenges in generating human-like music is articulating musical expressions such as dynamics, phrasing, and timbre, which are difficult for computational models to mimic. Previous efforts to tackle this problem have been insufficient due to a fundamental lack of data containing information about musical expressions. In this paper, we introduce MID-FiLD, a MIDI dataset for learning fine-level dynamics control. Notable properties of MID-FiLD are as follows: (1) All 4,422 MIDI samples are constructed by professional music writers with a strong understanding of composition and musical expression. (2) Each MIDI sample contains four different musical metadata and control change \#1 (CC\#1) value. We verify that our metadata is a key factor in MID-FiLD, exerting a substantial influence over produced CC\#1 values. In addition, we demonstrate the applicability of MID-FiLD to deep learning models by suggesting a token-based encoding methodology and reveal the potential for generating controllable, human-like musical expressions.
Adversarial Socialbots Modeling Based on Structural Information Principles

Published: March 2024

The importance of effective detection is underscored by the fact that socialbots imitate human behavior to propagate misinformation, leading to an ongoing competition between socialbots and detectors. Despite the rapid advancement of reactive detectors, the exploration of adversarial socialbot modeling remains incomplete, significantly hindering the development of proactive detectors. To address this issue, we propose a mathematical Structural Information principles-based Adversarial Socialbots Modeling framework, namely SIASM, to enable more accurate and effective modeling of adversarial behaviors. First, a heterogeneous graph is presented to integrate various users and rich activities in the original social network and measure its dynamic uncertainty as structural entropy. By minimizing the high-dimensional structural entropy, a hierarchical community structure of the social network is generated and referred to as the optimal encoding tree. Secondly, a novel method is designed to quantify influence by utilizing the assigned structural entropy, which helps reduce the computational cost of SIASM by filtering out uninfluential users. Besides, a new conditional structural entropy is defined between the socialbot and other users to guide the follower selection for network influence maximization. Extensive and comparative experiments on both homogeneous and heterogeneous social networks demonstrate that, compared with state-of-the-art baselines, the proposed SIASM framework yields substantial performance improvements in terms of network influence (up to 16.32%) and sustainable stealthiness (up to 16.29%) when evaluated against a robust detector with 90% accuracy.

Biologically Inspired Design (BID), or Biomimicry, is a problem-solving methodology that applies analogies from nature to solve engineering challenges. For example, Speedo engineers designed swimsuits based on shark skin. Finding relevant biological solutions for real-world problems poses significant challenges, both due to the limited biological knowledge engineers and designers typically possess and to the limited BID resources. Existing BID datasets are hand-curated and small, and scaling them up requires costly human annotations.

In this paper, we introduce BARcode (Biological Analogy Retriever), a search engine for automatically mining bio-inspirations from the web at scale. Using advances in natural language understanding and data programming, BARcode identifies potential inspirations for engineering challenges. Our experiments demonstrate that BARcode can retrieve inspirations that are valuable to engineers and designers tackling real-world problems, as well as recover famous historical BID examples. We release data and code; we view BARcode as a step towards addressing the challenges that have historically hindered the practical application of BID to engineering innovation.

Published: March 2024

Call-and-response is a musical technique that enriches the creativity of music, crafting coherent musical ideas that mirror the back-and-forth nature of human dialogue with distinct musical characteristics. Although this technique is integral to numerous musical compositions, it remains largely uncharted in automatic music composition. To enhance the creativity of machine-composed music, we first introduce the Call-Response Dataset (CRD) containing 19,155 annotated musical pairs and crafted comprehensive objective evaluation metrics for musical assessment. Then, we design a knowledge-enhanced learning-based method to bridge the gap between human and machine creativity. Specifically, we train the composition module using the call-response pairs, supplementing it with musical knowledge in terms of rhythm, melody, and harmony. Our experimental results underscore that our proposed model adeptly produces a wide variety of creative responses for various musical calls.
