IMPACTS OF TABLE TENNIS ON THE HEALTH OF YOUNG STUDENTS
Authors: Han Liang , Wang Rui
Published: December 2023

ABSTRACT Introduction By improving the material level of life, the amount of exercise of adolescents is decreasing, leading the muscular strength and cardiorespiratory resistance to also decrease instead of increase. Therefore, it is urgent to present effective training methods in physical education teaching to benefit adolescents’ quality of life. Objective Study the effect of table tennis training on musculature and cardiorespiratory endurance in young students. Methods 60 students from grade 7 of a high school were randomly divided into experimental and control groups. The experiment lasted for 9 weeks. In this paper, intra-group comparisons and inter-group comparisons were used. Before the experiment and after 9 weeks of training, students had their biophysical indicators collected; these data were analyzed and statistically compared. Results Existing physical education training can overall improve students’ physical muscular and cardiopulmonary endurance. The results show that the current training is effective, but inferior to that experienced with table tennis, and should be adjusted. Conclusion In teaching high school youth, physical education teachers are advised to promote table tennis to promote the young student’s health.

Authors: Ren Jinfeng
Published: December 2023

ABSTRACT Introduction In a scenario of continuous improvement of telecommunications network infrastructure and the maturation of related industrial chains, sports-oriented cell phone applications can meet the needs of different types of user groups due to their characteristics - close to the human body, able to collect users’ health, favorite sports, location, and other personal characteristic data in real-time. With the support of cloud computing, big data, and other techniques, the regularity of users’ sports health can be analyzed. Objective Explore the effect of obese college students’ use of cell phone apps on their exercise routines. Methods 53 obese college students volunteered for the research project. They were investigated by a questionnaire about their use of apps to aid exercise and health. Then, the participants’ exercise status was monitored, including weekly exercise time, exercise frequency, and exercise items, among other pertinent data. Finally, physical health data collected before and after the experiment were analyzed and statistically compared. Results Some obese college students did not acquire the habit of adhering to physical exercise, their psychological resilience and ability to fight frustration proved deficient, and the effect of an exercise assisted by cell phone apps left to be desired. However, for some obese college students who determined to exercise, the regular moderate exercise showed an improvement in physical health. Conclusion Exercise-focused health maintenance apps can stimulate obese college students’ enthusiasm for exercise, making the exercise process more enjoyable, controlled, and scientific. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

Authors: Jia Weihua
Published: December 2023

ABSTRACT Introduction Soccer is a sport with intense rivalry, where physical strength is a prerequisite to ensure high level of playability. Objective Explore the application of functional training in soccer training and its influence on soccer players’ specific physical fitness. Methods 24 s and divided into experimental and control groups into an experimental group and a control group. The control group underwent the intervention according to the normal program, while the experimental group used a functional training program protocol. The subjects’ FMS scores and special fitness and ss were tested before and after the experiment, the results were statistically analyzed and discussed in the light of up-to-date scientific literature. Results Before the experiment, the overall functional action screening scores of the two groups of players were low, and there was a high risk of sports injuries. After 12 weeks of training intervention, the experimental and control groups’ FMS scores were significantly elevated, indicating that traditional physical and functional training can effectively improve functional movement screening performance. Conclusion The 12 weeks suggested functional training protocol can significantly improve the physical fitness of soccer players.

From anthropology of things to anthropology of technology: Is there a place for co-production of techniques?
Authors: Villagómez-Reséndiz Radamés
Published: December 2023

Abstract We address the version of an ontological turn as a methodological imprint of the coproduction of knowledge. Although this perspective carries on a methodological effort to shed new light on object study through recursiveness, it neglects the importance of technical action. The present article aims to deepen the methodological venues offered by the ontological turn to address the notion of co-production related to techniques. Departing from the analyses of ethnographic contexts, we discuss whether experimentation as axes of co-production resonates with other methodological devices provided by the anthropology of technology. We argue that philistinism, inflection, and possibilism of material affordances colligate with experimentation reflected in different practices, overcoming representational bias and posthumanist excesses.

RESUMO Objetivo: Verificar a prevalência e identificar os fatores associados à ausência do acompanhante de parto em mulheres no sul do Brasil. Métodos: Trata-se de um estudo transversal, realizado com 466 parturientes, pertencentes a uma coorte de mulheres da zona urbana da cidade de Pelotas, RS. Aos 18 meses pós-parto, foi aplicado um questionário estruturado com dados sociodemográficos, gestacionais e questões relacionadas ao parto. Foi realizada regressão logística para ajustes de possíveis fatores de confusão. Resultados: A prevalência da ausência de acompanhante de parto entre as mulheres foi de 22,3%. As parturientes com até 8 anos de estudo (RP=2,0 [IC95% 1,1–3,8]), que não viviam com um companheiro (RP=2,3 [IC95% 1,2–4,3]), que realizaram o pré-natal no setor público (RP=1,9 [IC95% 1,0–3,7]) e que tiveram um parto via cesárea (RP=6,0 [IC95% 2,9–12,4]) apresentaram maior probabilidade de ausência de acompanhante de parto. Conclusão: Os resultados apontam evidências relevantes para o seguimento da verificação da presença do acompanhante de parto no sul do Brasil, indicando a necessidade de melhor aproveitamento e adesão desta prática. Além disso, a lei que aprova a presença do acompanhante de parto no Brasil parece não estar sendo colocada em prática de modo integral, desrespeitando um direito das parturientes e impactando nos benefícios para a saúde materno-infantil.

Published: December 2023

ABSTRACT Objective: This work aimed to estimate the avoidable COVID-19 cases and deaths with the anticipation of vaccination, additional doses, and effective non-pharmacological interventions in Brazil. Methods: We developed a susceptible-exposed-infectious-recovered-susceptible model based on epidemiological indicators of morbidity and mortality derived from data obtained from the Health Information System of the Ministry of Health of Brazil. The number of cases and deaths was estimated for different scenarios of vaccination programs and non-pharmacological interventions in the states of Brazil (from March 8, 2020, to June 5, 2022). Results: The model-based estimate showed that 40 days of vaccination anticipation, additional vaccine doses, and a higher level the nonpharmacological interventions would reduce and delay the pandemic peak. The country would have 17,121,749 fewer COVID-19 cases and 391,647 avoidable deaths Conclusion: The results suggest that if 80% of the Brazilian population had been vaccinated by May 2021, 59.83% of deaths would have been avoided in Brazil.

Abstract Objective To assess the effects of acupuncture on the relief of osteomuscular pain in older adults and the potential improvement in functionality for activities of daily living. Method A quasi-experimental study, with pre- and post-intervention assessment using the Visual Analog Scale and the Katz Index. Convenience sample comprising 31 older adults. The intervention period consisted of four weekly treatment sessions. Acupuncture intervention targeted a systemic treatment protocol utilizing five pairs of acupoints: LI4 (Hegu), LIV3 (Taichong), ST36 (Zusanli), PC6 (Neiguan), and SP6 (Sanyinjiao). Results 100% (31) reported experiencing pain, with 64.52% (20) reporting moderate pain (3-7), 25.81% (8) reporting severe pain (8-10), and 9.68% (3) reporting mild pain (0-2). The treatment protocol demonstrated positive outcomes after 4 sessions, with a reduction of pain to a mild degree and an overall average score reduced below 2. The analysis of results from the Visual Analog Scale and the Katz Index showed potential for the use of acupuncture in relieving osteomuscular pain and improving the functionality of the older adult. Conclusion The use of systemic acupuncture techniques yielded satisfactory results in the relief of osteomuscular pain and the enhancement of functionality for activities of daily living of the older adult.

Published: December 2023

Abstract Objective To investigate whether the risk of sarcopenia in older adults diagnosed with covid-19 is associated with the need for intensive care, mechanical ventilation, and mortality. Method A multicenter cohort study was conducted, including older adults (≥65 years) with laboratory-confirmed covid-19 diagnosis. Data related to sociodemographic, clinical, and nutritional characteristics were collected. The risk of sarcopenia was assessed using the Sarcopenia Risk Screening questionnaire. Outcome variables included the need for intensive care, mechanical ventilation, and mortality. Logistic regressions were performed to assess the association between clinical outcomes and the risk of sarcopenia, adjusting for the following variables: age, gender, family income, physical activity, hypertension, diabetes, cardiovascular disease, chronic obstructive pulmonary disease, and body mass index. Results The study included 264 older adults with covid-19, with an average age of 71.7 (±8.2) years. One hundred and forty-eight older adults (56.1%) were at risk of sarcopenia. Hypertension, diabetes, and cardiovascular disease were the most common comorbidities identified in older adults, at 75.4%, 45.5%, and 28.4%, respectively. The presence of sarcopenia risk in hospitalized older adults with covid-19 increased the odds of ICU admission by more than 2-fold (OR: 2.71 [1.57; 4.68], p<0.001), nearly 5-fold for mechanical ventilation (OR: 5.19 [2.75; 9.78], p<0.001), and over 3-fold for mortality (OR: 4.05 [2.05; 7.98], p<0.001). Conclusion In hospitalized older adults with covid-19, pre-existing risk of sarcopenia was a predictor of unfavorable clinical outcomes.

Published: December 2023

Abstract Introduction: The in situ simulation (ISS) consists of a training technique that takes place in the real workplace as a relevant method to promote environmental fidelity in the simulated scenario. Objective: To verify the use of the ISS in the world, to understand its applicability in healthcare. Method: This is an integrative review, which used the following guiding question: How has in situ simulation been used by health professionals? Searches were carried out in the PubMed, SciELO, LILACS and Web of Science databases, with different combinations of the following descriptors: in situ simulation, health and medicine (in Portuguese, English and Spanish) and the Boolean operators AND and OR using a temporal filter from 2012 to 2021. A total of 358 articles were found and the inclusion and exclusion criteria were applied, following the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA), and also with an independent peer review, using Rayyan, leaving 190 articles for this review. Results: The results showed that the United States has the absolute majority of productions (97/51%), followed by Canada, but with a large numerical difference (18/9.5%). Most of the works are written in English (184/96.8%), are quasi-experimental studies (97/51%), and have multidisciplinary teams as the target audience (155/81.6%). The articles have 11,315 participants and 2,268 simulation interventions. The main ISS scenarios were the urgent and emergency sectors (114/60%), followed by the ICU (17/9%), delivery room (16/8.42%) and surgical center (13/6.84%). The most frequently studied topics were CPR (27/14.21%), COVID-19 (21/11%), childbirth complications (13/6.8%) and trauma (11/5.8%). Discussion: The pointed-out advantages include the opportunity for professional updating with the acquisition of knowledge, skills and competencies, in an environment close to the real thing and at low cost, as it does not depend on expensive simulation centers. Conclusion: In situ simulation has been used by health professionals worldwide, as a health education strategy, with good results for learning and training at different moments of professional training, with improved care and low cost. There is still much to expand in relation to the use of ISS, especially in Brazil, in the publication of studies and experience reports on this approach.

Taxonomic notes on Asplenium pseudoangustum (Aspleniaceae): a redescription based on spore morphology and distribution novelties
Authors: Reis Atiles , Mynssen Claudine Massi , Lino Vanessa , Sylvestre Lana da Silva
Published: December 2023

Abstract Asplenium pseudoangustum is a poorly understood species known from the Peruvian Amazon forests. Due to morphological similarities with A. angustum and A. serratum, the position of A. pseudoangustum among the called A. serratum complex was suggested. However, spore ornamentation and scales morphology indicate that A. pseudoangustum is more related to the species of the A. hastatum subclade. Here, we present a redescription for this species, including scales and spore morphology, and an updated distribution including records from Brazil and Colombia.
As soft as silk: structural and chemical traits can help with the identification of Niphidium crassifolium (Polypodiaceae) gall inducers

Published: December 2023

Abstract Ferns have been poorly reported as hosts of gall inducers, and their multitrophic interactions and relationships are practically unknown to science. We focused on Niphidium crassifolium (Polypodiaceae) that hosts globoid leaf galls. The galls on N. crassifolium have only reported for the South and Southeast regions of Brazil, with a discussion regarding the identity of the gall inducer: is it a Cecidomyiidae-Diptera or to Coccidae-Hemiptera? These two insect groups have distinct characteristics and consequently their galls must have distinct anatomical and histochemical traits. Such traits may work out as functional tools to be used to confirm the taxa of the associated galling herbivore and to evaluate their geographic distribution. Our study aimed to expand the known distribution of N. crassifolium and its interactions based on an inventory of scientific articles and on herbarium data, and also to test the usefulness of anatomical and histochemical traits for proposing the identity of the gall inducer. The geographic distribution of N. crassifolium galls involves five South American countries, i.e., Bolivia, French Guiana, Guyana, Peru, and Brazil. The development of an outer tissue compartment with phenolic-rich cell layers and an inner nutritive tissue leads us to infer that the inducer belongs to the Cecidomyiidae family.
Rumohra aconquijana (Dryopteridaceae): a new species endemic from Southern Yungas in Argentina
Authors: Arana Marcelo Daniel , Bulacio Eva , Slanis Alberto Carlos , Grau Alfredo
Published: December 2023

Abstract Rumohra aconquijana sp. nov., a restricted endemism of the Montane Jungle district (700-1,500 m asl; Yungas biogeographic province) is reported, described and illustrated. Rumohra aconquijana grows as epiphyte on Ocotea porphyria (Lauraceae) and Sambucus peruviana (Viburnaceae) in humid terraces and slopes of the cloud forest. The new species differs from the widespread R. adiantiformis, especially by the dissection of the laminae, the shape and size of the pinnules. Also, there are differences with all Argentinean and Bolivian and Chilean species of Rumohra in the ornamentation of the perispore, which is folded with few folds, partially fused, narrow and with ridged margins. Here, we present the first species of Rumohra endemic from Argentinean Yungas, as well as a key to identifying the species occurring in Argentina and Bolivia.
Alterations induced by Tortrimosaica polypodivora on the stems of Microgramma vacciniifolia: simple or complex galls?
Authors: Martins Gabriela Soares , Santos Marcelo Guerra , Reis Atiles , Ferreira Bruno Garcia
Published: December 2023

Abstract Microgramma vacciniifolia, an epiphyte fern, hosts of two stem galls. One is induced by Tortrimosaica polypodivora (Lepidoptera), which can also induce galls in M. squamulosa and M. mortoniana. The alterations induced by T. polypodivora on M. vacciniifolia stem were compared to non-galled organs to evaluate the anatomical potentials of host ferns in response to a galling Lepidoptera. Histochemical and histometrical comparisons between galled and non-galled stems were performed to assess the processes leading to gall formation. M. vacciinifolia and M. squamulosa galls were anatomically similar, although their sizes differ, reflecting the growth potential of each host species. Simple structural alterations, such as hyperplasia of cortical and pericycle cells, occur during gall formation, while cell hypertrophy, common in more complex galls, was only detected on the pericycle. Meristele size remained unaltered in galls, but the pericycle appeared hyperplasic. The protective scales were broader in galls. A nutritive tissue with lipids, typical to Lepidoptera galls, was observed around the larval chamber, with small cells and meristematic activity. Starch, proteins, and reducing sugars accumulated in nutritive cells are uncommonly found in Lepidoptera galls. Despite simple structural alterations, T. polypodivora induced a gradient of primary metabolites, similar to angiosperm galls.
Palynomorphometry in ferns: Ctenitis (Dryopteridaceae), a case of study in the Southern Cone of America
Authors: Gorrer Daniel Alejandro
Published: December 2023

Abstract The morphometric knowledge about the spores of the Ctenitis has not yet been deepened. Considering the folded spores of this genus which inhabit the Southern Cone of America the aims were to increase infrageneric knowledge, to evaluate the relationship among the morphometric characters of the folded spores in these Ctenitis species and to verify the spore’s morphometry as a taxonomic tool. This study was performed with herbarium material. The spores were analyzed with light microscopy (LM) and scanning electron microscopy (SEM). The variables analyzed were: major and minor equatorial diameter, polar diameter, length of the laesura and length, width and height of the folds. The test chosen to analyze the study variables was ANOVA. Four spore sets are proposed. The “elongate-type” is made up of C. aspidioides and C. nervata. The “medium-type” is made up of C. anniesii, C. distans, C. falciculata and C. paranaensis. The “handle shape-type” is represented by C. bigarellae, C. eriocaulis and C. submarginalis. Finally, the “short-type”, consists only of C. deflexa. The morphometric data of spores together with the statistical analysis provided useful information for the distinction of some Ctenitis species studied in the Southern Cone of America. These results contribute to the studies aeropalynologycal and palaeopalynological.
Temporal dynamics of the superdominant bracken fern Pteridium arachnoideum in Neotropical savanna-riparian forest transitions
Authors: Dodonov Pavel , Xavier Rafael de Oliveira , Matos Dalva Maria da Silva
Published: December 2023

Abstract Clonal growth can be especially advantageous in spatially heterogeneous environments and some clonal plants are highly invasive or superdominant, especially in disturbed environments. However, their temporal dynamics in the absence of large disturbances are not well known. We assessed whether patches dominated by the native bracken fern Pteridium arachnoideum expanded or retracted in area over six years. We mapped the contour of eight patches occupied by P. arachnoideum in a savanna-forest transition every two years from 2009 to 2015. The area occupied by most patches was overall stable, indicating that forested patch boundaries may be unsuitable for an effective vegetative spread of P. arachnoideum. One patch fully retracted during the study period, possibly due to extensive herbivory by leafcutter ants. Thus, although clonal foraging may enable the spread of the species to more suitable sites from these patches, these results indicate that P. arachnoideum does not represent a threat to the biodiversity of savanna-riparian forest transitions in the absence of extensive disturbances, as the area of the largest patches remained stable or decreased during our study. These findings highlight that specific characteristics of the local disturbance regime may be key to the cost-effective management of some superdominant native species.

Physiological and biochemical changes in desiccation and rehydration cycles of Selaginella convoluta (Selaginellaceae)
Authors: Aidar Saulo de Tarso , Chaves Agnaldo Rodrigues de Melo , Fernandes-Júnior Paulo Ivan , Morgante Carolina Vianna
Published: December 2023

Abstract Vegetative desiccation tolerance (VDT) is a biological process that allows resurrection plants to complete desiccation-rehydration cycles and survive without permanent damage. Physiological and biochemical changes related to the VDT were evaluated in the lycophyte Selaginella convoluta from the Caatinga biome, a seasonally dry tropical forest of northeastern Brazil. As representative of the oldest division of extant vascular plants, the investigation of VDT mechanisms in this species serves as an opportunity to provide information for research communities interested in functional traits related to water-limited conditions. The experiments were performed with plants in their natural habitat, in dry and rainy seasons, and in pots under shade house conditions. Relative water content, chlorophyll a fluorescence, gas exchange, activity of antioxidant enzymes, concentration of chlorophylls, proteins, total amino acids, proline, and soluble carbohydrates in leaf tissues were evaluated throughout the process of complete dehydration and subsequent re-watering of intact plants. The overall results reveal the capacity of S. convoluta to tolerate extreme dehydration and rapidly recover upon rehydration. This species minimizes potential damages during the desiccation-rehydration cycle due to the presence of inductive mechanisms (photochemical preventing, sucrose accumulation) and constitutive mechanisms (antioxidant activity of catalase and ascorbate peroxidase), which share similarities with the VDT of both angiosperms and bryophytes.

Método estudo quantitativo e transversal, realizado com 216 enfermeiros de 97 municípios integrantes de duas Macrorregiões de Saúde do Estado de Santa Catarina, os quais responderam um questionário do tipo survey, no ano de 2019. Os dados passaram por estatística descritiva analítica e inferencial. Resultados entre as práticas assistenciais observou-se prevalência do acolhimento e da consulta do enfermeiro, o que fortalece a sua autonomia e a resolutividade da Atenção Primária, seguidos dos procedimentos de enfermagem. As visitas domiciliares sobressaem-se para a periodicidade de até três vezes por semana e as atividades educativas concentraram-se na periodicidade quinzenal. As atividades de educação em saúde voltam-se majoritariamente aos usuários portadores de patologias crônicas. Os enfermeiros privilegiam as abordagens assistenciais individuais, em detrimento às ações educativas em grupo. Conclusão e implicações para a prática há necessidade do fortalecimento da dimensão educativa, no trabalho do enfermeiro, que tangencie atividades assistenciais e gerenciais na Atenção Primária à Saúde, em especial, voltadas para grupos.
Estrutura sócio-ocupacional das metrópoles brasileiras: mudanças e permanências em 40 anos
Authors: Ribeiro Marcelo Gomes
Published: December 2023

Resumo O objetivo deste artigo é apresentar os resultados da análise da estrutura sócio-ocupacional das principais metrópoles do Brasil, entre os anos de 1982 e 2021, focando em sua composição e no comportamento das desigualdades de renda. Buscamos responder às seguintes questões: "Que mudanças e/ou permanências ocorreram na composição da estrutura sócio-ocupacional das metrópoles brasileiras?” e “Como as desigualdades de renda se apresentaram nessa estrutura sócio-ocupacional no período em análise?”. Foram utilizados dados Pnad, de 1982, e PnadC, de 2021, do IBGE. Os principais resultados encontrados apontam para a manutenção de uma estrutura social representada pelo modelo piramidal, apesar de mudanças importantes ocorridas ao longo de 40 anos, e para a redução das desigualdades de renda.
Socio-occupational structure of Brazilian metropolises: what changed and what remained the same in 40 years
Authors: Ribeiro Marcelo Gomes
Published: December 2023

Abstract This article analyzes the socio-occupational structure of the main Brazilian metropolises between 1982 and 2021, focusing on their composition and on the behavior of income inequalities. We seek to answer the following questions: “What changed and what remained the same in the composition of the socio-occupational structure of Brazilian metropolises?” and “How did income inequalities appear in this socio-occupational structure in the period under analysis?” PNAD data from 1982 and PNADC data from 2021, provided by IBGE, were used. Although important changes occurred in the 40-year period, the study’s main results point to the maintenance of a social structure represented by the pyramidal model and to a reduction in income inequalities.
Trabalho precariado e plataformização: comércio no circuito inferior da economia

Published: December 2023

Resumo No contexto de reestruturação capitalista, desindustrialização, reprimarização da pauta exportadora, rentismo, somam-se a economia da plataformização, a uberização e a crescente precariação do mundo do trabalho. Maracanaú, pertencente à Região Metropolitana de Fortaleza, não passa incólume pelas transformações ocorridas no cenário nacional. O objetivo deste artigo é analisar a dinâmica do circuito inferior da economia urbana nos territórios de comércio de confecção popular do município de Maracanaú. Conclui-se que esse comércio extrapola o território metropolitano e se reinventa em meio ao embate com o poder público e os interesses privados. Contudo, o direito ao trabalho na reforma urbana é um desafio diante do exército de excluídos, sendo negado o direito à cidade que se transformou em mercadoria, cidade do negócio.
State’s action in the production of the informal city: a spatial analysis in Florianópolis
Authors: Castelhano Pedro Jablinski , Maciorowski Maíra Mesquita , Beck Elisa de Oliveira
Published: December 2023

Abstract The thesis that the Brazilian state tolerates and encourages urban squatting as a response to its own inability to provide popular housing and to guarantee jobs that enable the acquisition of housing in the real estate market is tested in this article through the case study of Florianópolis. We studied irregularity and two indications of municipal action in its consolidation in Florianópolis: implementation of community facilities and issuance of construction permits. We found that construction permits are limited only by registration restrictions, not by the existence or not of land ownership, and that the municipality works actively in the production of health, education, and transport facilities, but not of leisure facilities in these areas.
O urbano como antinação: para entender a crise das metrópoles brasileiras
Authors: Ribeiro Luiz César de Queiroz , Matela Igor Pouchain , Diniz Nelson
Published: December 2023

Resumo Como retomar um projeto de desenvolvimento que contemple a reforma urbana e o direito à cidade? Buscamos esboçar um marco teórico-analítico compatível com essa possibilidade, entendendo que as cidades brasileiras podem funcionar como vetores da reconstrução da nação, após o período recente de sucessivas crises, com destaque para a crise urbana. Propomos adotar horizontes amplos de investigação dos “problemas urbanos”, sustentando que eles devem ser considerados à luz da forma histórica contemporânea da dependência e das circunstâncias abertas com o golpe de 2016, que impôs uma inflexão ultraliberal ao País. Defendemos, por fim, que, após esse golpe, o “caráter antinacional do urbano” foi radicalizado e que sua compreensão pode se beneficiar do resgate do debate sobre a urbanização dependente.
Two periods of Brazilian neoliberalism as city government
Authors: Costa André Dal’Bó da
Published: December 2023

Abstract This article discusses two different phases of neoliberalism as city government practice in Brazil: the first one as progressive neoliberalism and the second as authoritarian, austere, and militarized management of social collapse. In the first part of the text, I use the works of Christian Laval and Pierre Dardot (2009 [2013] and 2016) and Dardot et. al (2021) to inscribe the proposed debate in the transition between two expressions of neoliberalism, initially as world reason or political rationality and later as war strategy. In the second part, such phases will be observed through recent transformations in city government practices, using some examples related to the latest housing and land regularization programs.
Caos e nova temporalidade do sistema-mundo contemporâneo
Authors: Martins Carlos Eduardo
Published: December 2023

Resumo Apresentamos cinco grandes teses para entender a nova conjuntura mundial em que ingressam o capitalismo e a humanidade a partir de 2015-2020. Esse período se caracteriza pela crise do modo de produção e da civilização capitalista; pela crise terminal e desmonte da hegemonia dos Estados Unidos; pela bifurcação geopolítica da economia mundial em um bloco imperialista liderado pelos Estados Unidos e outro emergente centrado na China, na Rússia e sua ampliação para o Sul Global; pela crise ideológica do liberalismo global e a ascensão do fascismo e do socialismo como alternativas; pela crise do padrão de acumulação neoliberal e o esgotamento da fase expansiva do Kondratieff iniciada em 1994. Indicamos brevemente os efeitos dessas tendências sobre a América Latina.
Assessment of left-censored data treatment methods using stochastic simulation
Authors: Silva Fábio Henrique Rodrigues da , Pinto Éber José de Andrade
Published: December 2023

ABSTRACT The paper evaluates the influence of size series, percentage of censored data, and coefficients of variation used to generate synthetic series on the estimation of means, standard deviations, coefficients of variation, and medians in series with censored data. Seven techniques were applied to treat censored data in synthetic series with 180 scenarios (four size series, nine censoring percentages and five coefficients of variation): values proportional to the DL: zero, DL/2, DL/20.5 and DL - and parametric (MLE), robust (ROS) and Kaplan-Meier methods. Predictions were analyzed with four performance metrics (MPE, MAPE, KGE, and RMSE). It is found that the percentage of censored data and the coefficient of variation significantly alter forecast quality. It is also found that substitution by DL/2, by DL/20.5 and ROS are the most appropriate techniques for estimating the variables described, emphasizing ROS when estimating parametric variables and substitution by DL/20.5 for medians.

Authors: Silva Juliana de Souza , Silva Katiene Nogueira da
Published: December 2023

Resumo O texto apresenta entrevista realizada com Myriam Krasilchik, Professora Emérita do Departamento de Metodologia do Ensino e Educação Comparada da Faculdade de Educação da Universidade de São Paulo (FE-USP), feita por ocasião das comemorações de 50 anos da Faculdade de Educação e 60 anos da Escola de Aplicação da USP, ocorridas no ano de 2019. Considerando sua notável dedicação à Universidade de São Paulo e a relevância das pesquisas em Ensino de Ciências e Biologia, que lhe proporcionaram o reconhecimento, também, entre os professores de Educação Básica, buscamos, a partir das memórias compartilhadas conosco, conhecermos suas lembranças mais marcantes quando aluna do curso de História Natural da antiga Faculdade de Filosofia, Letras e Ciências da USP (FFLC) e aquelas de quando se tornou docente do ensino superior, realizando a pós-graduação já em exercício como professora universitária. A docente teve papel destacado e marcante na Faculdade de Educação, contribuindo para a formação de toda uma geração de pesquisadores da área de Ensino de Ciências e para a criação do bemsucedido Programa de Aperfeiçoamento do Ensino (PAE), que até hoje contribui para a formação pedagógica de estudantes de pós-graduação. Além disso, foi a primeira mulher a ocupar o cargo de gestora da unidade e de vice-reitora da universidade. Aproveitamonos de sua vasta experiência institucional para, também, questioná-la acerca de suas expectativas em relação à universidade de hoje.
State of the art research in education: characteristics and challenges
Authors: Jacomini Márcia Aparecida , Wellen Hericka Karla Alencar de Medeiros , Perrella Cileda dos Santos Sant’Anna , Monção Maria Aparecida Guedes
Published: December 2023

Abstract In this article, a systematic review study was carried out based on the analysis of 47 productions resulting from state-of-the-art research, selected from a universe of 113 review studies produced in the period from 2000 to 2016: articles published in national journals of the area of education, registered in SciELO; books and the Inep’s Estado do Conhecimento Series. The objective of the article was to analyze the theoreticalmethodological characteristics of the research, identify the challenges to its realization and indicate trends, potentialities and challenges to metaknowledge in the field of education. As a result, it can be stated that there is a common basic repertoire on the methodological design of states of the art shared by researchers, but it is still necessary to advance in establishing criteria that are fundamental to the development of these studies, which can be systematized into four main challenges: greater dialogue with the literature on review studies; creation of networks of researchers; advance in the complete reading of the works or read parts that may bring relevant information about the characteristics of the research, such as introduction, methodology and conclusions; improve and increase research that maps, evaluates and produces syntheses to guide researchers and their commitment to science and social demands.
