Resumo Interpreto as relações entre o abandono e a rememoração a partir das possibilidades de ressignificação da Fábrica de Cimento Portland de Perus. Abandonada desde a década de 1970, as instalações da falida Companhia Brasileira de Cimento Portland são, hoje, objeto de ações culturais de movimentos sociais de Perus, distrito da zona noroeste da Cidade de São Paulo. Estes procuram retomar memórias pessoais e coletivas da chamada Greve dos Queixadas, que tomou a Fábrica durante sete anos e legou ao território uma identidade de luta por direitos e cidadania.

Abstract In this paper, I interpret the relationship between abandonment and remembrance based on possibilities for re-signifying the Perus Portland Cement Factory. Abandoned since the 1970s, the facilities of the bankrupt Companhia Brasileira de Cimento Portland are today the object of cultural actions organized by social movements in Perus, a district in the northwest of the city of São Paulo. The movements aim to recapture personal and collective memories of the so-called Queixadas Strike, which took over the factory for seven years and left to the territory an identity of struggle for rights and citizenship. Based on the analysis of interviews, I discuss the counter-narrative created by one of these collectives, the Comunidade Cultural Quilombaque, to oppose oblivion and announce the potential of its territory. paper resignifying re signifying Factory 1970s s Paulo socalled so called Strike citizenship interviews counternarrative counter narrative collectives Quilombaque

SUMMARY: Because horned animals are prone to conflict, they may have a higher risk of developing a brain contusion as a result of a horn strike. Repeated brain trauma can affect the hippocampus, which is involved in memory and orientation. The aim of this study was to histopathologically examine the blood-brain barrier (BBB) of the hippocampus in horned and hornless female sheep. Skulls of 4 horned and 6 hornless female sheep aged 16±4 months were obtained from the abattoir. Brains were carefully removed and preserved in 10 % formalin for 5 days. Sections were taken from bilateral hippocampus. Specimens were stained with hematoxylin-eosin (H&E) and Tunel methods, and the histopathologic structures of the BBB were examined by light microscopy. BBB damage scores evaluated. The results were analyzed by Mann-Whitney U test. The BBB damage score was found to be higher in horned female sheep. Astrocytes was more branching and BBB was more intact in hornless female sheep. This is considered that more astrocyte branches may play an important role in the protective mechanism. The difference in intracerebral defense mechanism against brain trauma in female sheep may serve as a model for investigating molecular mechanisms. The impairment of the BBB in the hippocampal region of horned female sheep may result in their memory, intelligence, and navigational abilities being lower than those of hornless female sheep. This could open the horizon for better advances in human and animal brain health.

RESUMEN: Debido a que los animales con cuernos son propensos a los conflictos, pueden tener un mayor riesgo de desarrollar una contusión cerebral como resultado de un golpe con un cuerno. Los traumatismos cerebrales reiterados pueden afectar el hipocampo relacionado con la memoria y la orientación. El objetivo de este estudio fue examinar histopatológicamente la barrera hematoencefálica (BHE) del hipocampo en ovejas con y sin cuernos. Se obtuvieron de un matadero los cráneos de 4 ovejas con cuernos y 6 sin cuernos de 16 ± 4 meses de edad. Los cerebros se extrajeron cuidadosamente y se conservaron en formalina al 10 % durante 5 días. Se tomaron secciones del hipocampo bilateral. Las muestras se tiñeron con hematoxilina-eosina (H&E) y métodos Tunel, y las estructuras histopatológicas de la BHE se examinaron mediante microscopía óptica. Se evaluaron las puntuaciones de daño de la BHE. Los resultados fueron analizados mediante la prueba U de Mann-Whitney. Se descubrió que la puntuación de daño de la BHE era mayor en las ovejas con cuernos. Los astrocitos estaban más ramificados y la BHE estaba más intacta en las ovejas sin cuernos. Se considera que más ramas de astrocitos pueden desempeñar un papel importante en el mecanismo de protección. La diferencia en el mecanismo de defensa intracerebral contra el trauma cerebral en las ovejas puede servir como modelo para investigar los mecanismos moleculares. El deterioro de la BHE en la región del hipocampo de las ovejas con cuernos puede provocar que su memoria, inteligencia y capacidades de orientación sean inferiores a las de las ovejas sin cuernos. Esto podría abrir el horizonte para mejores avances en la salud del cerebro humano y animal.

RESUMO A pandemia da Covid-19 colocou importantes desafios sanitários e económicos aos Estados e às suas burocracias. Tanto nos países desenvolvidos como nos países em desenvolvimento, as políticas implementadas reativaram as discussões sobre o papel do Estado e os seus graus de intervenção. Da mesma forma, implicaram mudanças nas condições de trabalho dos servidores públicos em função das medidas de cuidado e isolamento adotadas. Estas mudanças tiveram impacto na dinâmica das disputas trabalhistas no sector? Os conflitos registrados apresentaram novas características? Houve diferenças dependendo do nível de governo? Este artigo analisa os conflitos trabalhistas promovidos pelos trabalhadores das Administrações Públicas municipais, provinciais e nacional durante o período 2020-2022. Para caracterizar as estratégias adotadas nesta situação excepcional, são abordados especificamente os tipos de reclamações e o repertório de ações desenvolvidas foram aquelas com ou sem greve. Os dados são comparados também com os registros pré-pandêmicos. A análise desenvolvida alimenta-se da integração de dados da Base de Conflitos Trabalhistas do Ministério do Trabalho, Emprego e Seguridade Social, regulamentos, documentos oficiais e artigos de jornais. Este trabalho procura fornecer evidências empíricas que sirvam ao debate mais amplo sobre as disputas trabalhistas no setor público.

RESUMEN La pandemia de la Covid-19 concitó importantes desafíos sanitarios y económicos para los Estados y sus burocracias. Tanto en países desarrollados como en vías de desarrollo, las políticas implementadas para mitigar su impacto reactivaron las discusiones respecto del rol del Estado y sus grados de intervención. Asimismo, implicaron cambios en las condiciones de trabajo de los empleados de las Administraciones Públicas pues debieron readaptar el modo de desempeñar sus tareas ante las medidas de cuidado y aislamiento dispuestas. ¿Estos cambios impactaron sobre la dinámica de la conflictividad laboral en el sector? ¿Los conflictos laborales registrados presentaron características novedosas? ¿Existieron diferencias según el nivel de gobierno? En este trabajo se analiza el caso argentino considerando los conflictos laborales impulsados por los trabajadores de las Administraciones Públicas municipales, provinciales y nacional durante el período 2020-2022. A fin de determinar las estrategias desplegadas en ese contexto de excepcionalidad, se abordan específicamente los tipos de reclamos planteados y el repertorio de acciones desarrolladas fueran éstas con o sin paro. Asimismo para ampliar la caracterización, los datos son comparados con lo ocurrido durante 2019, año previo a la declaración de la pandemia. El análisis realizado se nutre de la integración de datos provenientes de la Base de Conflictos Laborales del Ministerio de Trabajo, Empleo y Seguridad Social de la Nación (MTEySS), normativas, documentos oficiales y artículos periodísticos. Mediante este trabajo se procura aportar evidencia empírica que sirva al debate más amplio respecto de la conflictividad laboral en el sector público.

ABSTRACT The COVID-19 pandemic raised important health and economic challenges for the States and their bureaucracies. In both developed and developing countries, the policies implemented restarted the discussions regarding the role of the State and its degrees of intervention. Likewise, they implied changes in public servants’ working conditions in light of care and isolation measures taken. Did these changes have an impact on Public Administration labor conflict dynamic? Did labor conflicts present new characteristics under pandemic context? Were there any differences depending on the level of government? This paper analyzes labor conflicts promoted by Argentine public servants of municipal, provincial and national Public Administrations during the period 2020-2022. In order to characterize their strategies in this exceptional situation, the types of claims and their repertoire of actions (strike and non-strike disputes) are specifically addressed. The data are also compared with pre-pandemic figures. The analysis is based on the data of the Labor Conflict Base of the National Ministry of Labor, Employment and Social Security, regulations, official documents and newspaper articles. This work provides empirical evidence that contributes to the broadest debate about the labor conflicts in the public sector.

RESUMO Nos últimos 30 anos, ocorreram transformações significativas nas relações de trabalho, no sindicalismo e na própria comunicação sindical no Brasil. O avanço do neoliberalismo e das plataformas online expandiu a informalidade, fragmentou as organizações da classe trabalhadora e produziu um proletariado da era digital ainda mais precarizado. Sob os efeitos do capitalismo de plataforma, os trabalhadores de aplicativos começaram a experimentar novos arranjos de resistência a partir da convergência midiática e das possibilidades de existir e lutar em ambientes digitais. Este artigo analisa as experiências de comunicação do grupo de moto-entregadores Galera da Pressão (GDP), em atividade na cidade de Natal, no Estado do Rio Grande do Norte, desde 2020. As reflexões buscaram identificar possíveis semelhanças e diferenças com a tradicional comunicação sindical, a partir da observação de uma paralisação liderada pelo coletivo, em maio de 2022, cujas ações foram registradas no Instagram do grupo.

RESUMEN En los últimos 30 años se han producido importantes transformaciones en las relaciones laborales, en el sindicalismo y en la propia comunicación sindical en Brasil. El avance del neoliberalismo y de las plataformas online ha expandido la informalidad, fragmentado las organizaciones de la clase trabajadora y producido un proletariado de la era digital aún más precario. Bajo los efectos del capitalismo de plataformas, los trabajadores de las aplicaciones han comenzado a experimentar nuevos dispositivos de resistencia basados en la convergencia mediática y en las posibilidades de existir y luchar en entornos digitales. Este artículo analiza las experiencias de comunicación del grupo de repartidores en moto Galera da Pressão (GDP), activo en la ciudad de Natal, en el estado de Rio Grande do Norte, desde 2020. Las reflexiones buscaron identificar posibles similitudes y diferencias con la comunicación sindical tradicional, a partir de la observación de una huelga protagonizada por el colectivo en mayo de 2022, cuyas acciones fueron registradas en la cuenta de Instagram del grupo.

ABSTRACT In the last 30 years, significant transformations have occurred in labor relations, unionism, and union communication itself in Brazil. The advance of neoliberalism and online platforms has expanded informality, fragmented working class organizations, and produced an even more precarious digital age proletariat. Under the effects of platform capitalism, app-based workers began to experiment with new resistance arrangements based on media convergence and the possibilities of existing and fighting in digital environments. This article analyzes the communication experiences of the group of delivery motorcyclists Galera da Pressão (GDP), which has been operating in the city of Natal, in the state of Rio Grande do Norte, since 2020. The reflections sought to identify possible similarities and differences with the traditional union communication, based on the observation of a strike led by the collective, in May 2022, whose actions were recorded on the group's Instagram.

Abstract The present paper is part of ongoing doctoral research in political science in Brazil. It explores the advent of the Anthropocene as an ethical and political phenomenon, highlighting the transformation of humanity into a geological force and its political and epistemological consequences. We address the key role of young people in climate activism, that is in new movements such as End Fossil Occupy, the Student Climate Strike and Climáximo in Lisbon, Portugal. We hypothesise that the Anthropocene requires its own form of politics. Consequently, the narratives of young people in Portugal contribute significantly to establishing this new political paradigm. The article is, therefore, divided into four parts, in addition to the introduction and concluding remarks. First, we analyse the concept of the Anthropocene and its weaknesses, and Latour's views of this reality, commonly referred to as a war of worlds. This is followed by a brief discussion of climate activism in recent decades, and the description of the research methodology. The field experience in Portugal in October 2023 offers an enriching overview of the active involvement of Portuguese youth in the light of the emerging climate crisis. Finally, we share the field experience and the dialogue between these youth movements in the Portuguese capital. The aim is to provide an overview of the intersection between the Anthropocene, climate activism and the prospects of Portuguese youth.

Resumo Este artigo faz parte de uma pesquisa de doutorado, ainda em andamento, em ciência política no Brasil. O texto explora a emergência do antropoceno como fenômeno ético-político, destacando a transformação da humanidade em uma força geológica e suas implicações políticas e epistemológicas. Abordamos o papel central das juventudes no ativismo climático, como o surgimento de movimentos como End Fossil Occupy, a Greve Climática Estudantil e o Climáximo, em Lisboa, Portugal. Nossa hipótese é que o antropoceno exige um fazer político próprio. Dentro desse cenário, as narrativas das juventudes em Portugal emergem como contribuições significativas para a definição desse novo paradigma político. Portanto, o artigo estrutura-se em quatro partes, além da introdução e das considerações finais. Primeiro, analisamos o conceito de antropoceno, e suas debilidades, e a perspectiva de Latour sobre essa realidade, comumente referida como uma guerra de mundos; depois, abordamos sucintamente o ativismo climático nas últimas décadas; em seguida, apresentamos a metodologia de pesquisa, com base na vivência de campo em Portugal, durante outubro de 2023, que oferece uma perspectiva enriquecedora sobre o envolvimento ativo da juventude portuguesa face à iminente crise climática. Por fim, compartilhamos a experiência de campo e o diálogo estabelecido entre aqueles movimentos de juventude na capital portuguesa. O objetivo é fornecer um panorama da interseção entre o antropoceno, o ativismo climático e as perspectivas das juventudes portuguesas.

Resumo Este artigo analisa as experiências de participação na greve realizada pelos estudantes da Unidade 071 da Universidade Pedagógica Nacional em Tuxtla Gutiérrez, Chiapas, México. A partir de uma abordagem reflexiva, recupera-se a memória histórica do processo a partir da análise documental, de registos de assembleias e marchas, bem como de entrevistas com estudantes e dirigentes do movimento. A informação foi agrupada em dois blocos: Da pandemia à greve estudantil. Subjetivação e trama existencial; em que se expõem as vicissitudes da organização e das acções realizadas; e, A palavra deve valer, que aborda a rede de acções, sinergias, encontros e desencontros entre estudantes para empreender negociações com as autoridades educativas e governamentais. A confluência de outros movimentos sociais, a mobilização e a tomada das ruas, contribuíram para a resolução da greve, que inaugurou uma experiência inédita de luta e resistência para esses estudantes.

Resumen En este trabajo, se analizan las vivencias de participación en la huelga realizada por estudiantes de la Unidad 071, de la Universidad Pedagógica Nacional de Tuxtla Gutiérrez, Chiapas, México. Desde un enfoque reflexivo, se recupera la memoria histórica del proceso a partir del análisis documental, registros de asambleas y marchas, así como entrevistas a estudiantes y líderes del movimiento. La información se agrupó en dos bloques: De la pandemia al paro estudiantil. Subjetivación y trama existencial, en el que se exponen las vicisitudes de organización y acciones realizadas; y La palabra debe valer, que discute el entramado de acciones, sinergias, encuentros y desencuentros entre los estudiantes para acometer las negociaciones con las autoridades educativas y gubernamentales. La confluencia de otros movimientos sociales, la movilización y toma de las calles coadyuvó a la resolución de la huelga, lo que inaugura una experiencia inédita de lucha y resistencia para estos estudiantes.

Abstract This paper analyzes the experiences of participation in the strike carried out by students of Unit 071 of the National Pedagogical University of Tuxtla Gutierrez, Chiapas, Mexico. From a reflective approach, the historical memory of the process is recovered from documentary analysis, records of assemblies and marches, as well interviews with students and leaders of the movement. The information was grouped into two blocks: From the pandemic to the student strike. Subjectivation and existential plot; in which the vicissitudes of organization and actions carried out are exposed; and, The word must be worth, which discusses the network of actions, synergies, meetings and disagreements between students to undertake negotiations with educational and governmental authorities. The confluence of other social movements, the mobilization and taking of the streets, contributed to the strike's resolution, which inaugurated an unprecedented experience of struggle and resistance for these students.

Flow Characteristics (FC) is one of the few methods developed for predicting long-term sustainable borehole yield of single wells in typical fractured rock aquifers. The FC method uses drawdown derivatives and subjective information on no-flow boundaries to estimate a sustainable borehole yield that should not cause the water level to drop below the main water strike (fracture) during long-term operations. Since its development, the FC method has been widely applied in many research and consulting projects. Two decades after its development, a review of its technical capabilities and limitations is necessary to enhance understanding among groundwater practitioners while building a platform for further improvements. The main strength of the method is its simplicity of use, its ability to protect the main water strike/fracture, and its lower susceptibility to the influence of aquifer heterogeneities because it does not require the input of aquifer storativity and transmissivity. The FC method also caters to the negative influence of impermeable boundaries, thereby enabling planning for different low-yield-causing scenarios. However, the major limitation is in using the subjective closed no-flow boundary without factoring aquifer storativity and the distance of the closed no-flow boundary from the pumping well. Under the influence of the closed no-flow boundary, the water must come from aquifer storage, hence the storativity and the size of the bounded aquifer are very critical parameters. It is therefore incorrect to factor in the influence of the closed no-flow boundary without considering its exact location. This limitation is reflected in the absence of criteria to determine the distance of the closed no-flow boundary from the pumping well for validating the FC results using numerical models. The FC method still needs validation using field operational data; other recommendations for future research are highlighted in the discussion.

A research project was carried out on a gold mine in the Vaal River region of South Africa (Witwatersrand Basin) to evaluate the effect of two particular aspects of rockbolt installation - the angle of inclination of the bolt relative to the orientation of the rock surface, and the protruding length of the bolt - on the mine's gully support system. A keyblock analysis approach indicated that these factors do not have an adverse impact on the stability of the strike gullies. This was confirmed by extensive empirical data collected from the case study mine. While safety is the primary concern, cost saving opportunities can be realized through reconsidering historically inherited support standards that are perceived to be correct and appropriate. The research described in this paper sets forth a practical approach, that is easy to implement and repeatable, to evaluate the role of rockbolts in stoping gullies.

In recent years, concern about the prevention of online sexual abuse has increased. Research has highlighted the role of parents or guardians as preventive agents, using measures of control, supervision, and emotional support with their children. However, more needs to be understood about the balance that parents should strike between supervision and emotional support. The main objective of this study was to find out if adolescents with parents who have different supervision-support profiles present differences in factors linked to the prevention of OSA (knowledge about online sexual abuse, frequency of Internet use, self-efficacy, and well-being). The Participants were 82 high school students residing in Chile who responded to a series of self-report instruments. The cluster analysis recognized three groups of adolescents (with parents with high competence in the use of technology but with different levels of support and supervision). Adolescents with competent, supportive, and supervising parents best understand the risks of the Internet and have better self-efficacy and greater well-being.

En los últimos años ha aumentado la preocupación por la prevención del abuso sexual en línea. Las investigaciones han destacado el papel de los padres o tutores como agentes preventivos, utilizando medidas de control, supervisión y apoyo emocional con sus hijos. Sin embargo, es necesario comprender más sobre el equilibrio que los padres deben lograr entre el control, la supervisión y el apoyo emocional. El principal objetivo de este estudio fue conocer si adolescentes con padres que tienen diferentes perfiles de supervisión-apoyo presentan diferencias en factores vinculados a la prevención del abuso sexual en línea (conocimiento sobre abuso sexual en línea, frecuencia de uso de Internet, autoeficacia y bienestar). Los participantes fueron 82 estudiantes de secundaria residentes en Chile que respondieron a una serie de instrumentos de autoinforme. El análisis de conglomerados reconoció 3 grupos de adolescentes (con padres con alta competencia en el uso de la tecnología, pero con diferentes niveles de apoyo y supervisión). Los adolescentes con padres competentes, comprensivos y que supervisaban a sus hijos en el uso de Internet son los que mejor comprenden los riesgos de Internet, tienen mayor autoeficacia y reportan mayor bienestar.

Abstract To further improve the strike accuracy and penetration power of explosively-formed projectile (EFP) after long-distance flight, a polygonal charge capable of forming EFP with tail fins was designed during the study. A model for calculating the EFP velocity was derived from the effective charge and detonation projection theories with the integration of calculus. The circumferential velocity distributions of EFP formed using polygonal charges were obtained using this model, and the mechanisms underlying the formation of tail fins were elucidated. The feasibility of using this polygonal charge to form tail fin EFP was verified by conducting multi-media soft recovery tests and numerical simulations. Furthermore, the feasibility of forming tail fin EFP using polygonal charges with different numbers of sides and the effects of the structural parameters of a hexagonal charge on the formation of tail fin EFP were investigated by simulation. The ranges of optimal values for the structural parameters of a hexagonal charge capable of forming high-performance tail fin EFPs were determined. explosivelyformed explosively (EFP longdistance long distance flight study calculus elucidated multimedia multi media simulations Furthermore simulation highperformance high performance determined

This study investigated the effects of a foot core intervention on the coordination of foot joints in recreational runners. This was a secondary analysis from a randomized controlled trial conducted with 87 recreational runners allocated to the control group (CG), which followed a placebo lower limb stretching protocol, or the intervention group (IG), which underwent an 8-week (3 times/week) foot core training. The participants ran on a force-instrumented treadmill at a self-selected speed (9.5-10.5 km/h) while the foot segment motion was captured. The vector coding technique was used to assess inter-joint coordination for four selected coupled segment and joint angles. The coordination patterns of the calcaneus and midfoot (CalMid) and midfoot and metatarsus (MidMet) joint pairs were affected. In the frontal plane, IG showed an in-phase with proximal dominancy coordination at heel strike, with a decrease in its frequency after the training (P=0.018), suggesting a longer foot supination. Additionally, IG showed an anti-phase with distal dominancy pattern at early stance compared to CG due to a smaller but earlier inversion of the CalMid-MidMet pair (P=0.020). The intervention also had an effect on the transverse plane of the CalMid-MidMet pair, with IG showing a significantly greater frequency of anti-phase coordination with proximal dominancy during propulsion than CG (P=0.013), probably due to a reduction in the CalMid abduction. Overall, the results suggested that the foot core intervention reduces the occurrence of running-related injuries by increasing the resistance to calcaneus pronation and building a more rigid and efficient lever during push-off. 8 CG, , (CG) protocol IG, (IG) 8week week 3 ( times/week timesweek times forceinstrumented force instrumented selfselected self 9.510.5 95105 9.5 10.5 9 5 10 (9.5-10. km/h kmh km h captured interjoint inter angles (CalMid MidMet (MidMet affected inphase phase strike P=0.018, P0018 P P=0.018 0 018 (P=0.018) supination Additionally antiphase anti CalMidMidMet P=0.020.

Abstract This article delves into the reflections of a case study that focuses on the relationship between: (i) a strike in the eucalyptus cultivation sector in the state of Bahia; (ii) a partial process of reversing outsourcing (primarization) in the same sector. The article starts with a theoretical discussion of the role of outsourcing in the current strategy of capital domination over labor. It then looks at the relationship between outsourcing and trade unionism, addressing its implications for workers' organization and resistance. It then briefly recounts the strike and the fight against primarization. To do this, it is based on field research (interviews with ten trade unionists) and documents. The analysis leads to the conclusion that a central feature of the labor union was essential to the relative success of the strike in confronting outsourcing: the joint organization of outsourced and nuclear workers. i (i Bahia ii (ii primarization (primarization unionism workers resistance this interviews unionists documents

Resumo Este artigo aprofunda as reflexões de um estudo de caso que tem como objeto a relação entre: (i) uma greve no ramo do cultivo de eucalipto no estado da Bahia; (ii) um processo parcial de reversão das terceirizações (primarizações) no mesmo setor. O artigo parte de uma discussão teórica sobre o papel da terceirização dentro da estratégia atual de dominação do capital sobre o trabalho. Na sequência, trata da relação entre a terceirização e o sindicalismo, abordando as suas implicações para a organização e resistência dos trabalhadores. Em seguida, realiza uma breve reconstituição da greve e da luta pela primarização. Para isso, se baseia em uma pesquisa de campo (entrevistas com dez sindicalistas) e documental. A análise conduz à conclusão de que uma característica central do sindicato trabalhista foi essencial para o relativo êxito da greve no enfrentamento à terceirização: a organização conjunta entre trabalhadores terceirizados e nucleares. i (i Bahia ii (ii primarizações (primarizações setor trabalho sequência sindicalismo seguida primarização isso entrevistas sindicalistas documental nucleares

Abstract: In the context of the right to strike among members of the police force, two positions can be identified: on one side, there are those who predominantly argue that it is legitimate to limit or even suppress this right for this group of workers, and on the other side, there are those who contend that the right to strike is a labor right recognized in the Constitution without exceptions. This paper approaches this topic from a fresh perspective that, through an interpretation of Article 57 of the Constitution alongside other constitutional provisions and the principles of human rights protection, supports the thesis that public officials, including members of the police force, have a recognized right to strike

Resumen: En el derecho de huelga en el contexto de los miembros de las fuerzas policiales se pueden identificar dos posiciones: por un lado, quienes mayoritariamente sostienen que es legítimo limitar o incluso suprimir este derecho para este grupo de trabajadores, y, por el otro, quienes defienden que el derecho de huelga es un derecho gremial reconocido en la Constitución sin exclusiones. Este trabajo aborda este tema desde una nueva perspectiva que, a partir de una interpretación del artículo 57 de la Constitución en conjunto con otras disposiciones constitucionales y los principios de protección de los derechos humanos, respalda la tesis de que los funcionarios públicos, incluidos los miembros de las fuerzas policiales, tienen reconocido el derecho de huelga

Resumo: Quando falamos do direito à greve no âmbito dos membros das forças policiais, duas posições podem ser identificadas: por um lado, aqueles que em sua maioria defendem que é legítimo limitar ou mesmo suprimir esse direito para esse grupo de trabalhadores, e, por outro, aqueles que defendem que o direito à greve é um direito sindical reconhecido na Constituição sem exclusões. Este trabalho aborda esta questão apresentando uma nova perspectiva que, a partir de uma interpretação do artigo 57 da Constituição em conjunto com outros dispositivos constitucionais e os princípios de proteção dos direitos humanos, sustenta a tese de que os agentes públicos, incluindo os membros das forças policiais, têm reconhecido o direito à greve

Abstract Formed during marine regression periods, shelf valleys (SVs) are preterit river flows on the exposed continental shelf. This study investigates the influence of tectonic activity on forming these important morphological features. This research combines bathymetric, magnetometry, and seismic data to analyze the role of tectonic events in SV genesis and positioning. The bathymetric dataset provides information on SV locations and geometries along the continental shelf, whereas the 2D seismic sections illustrate that SVs formed above post-rift faults that reached Quaternary deposits. Aeromagnetic data indicates that the shallow and deep structures of the basement and sedimentary column-controlled SV locations and evolution. The multi-data integration demonstrates a strong correlation between neotectonic structures and SV location and geometries from the inner shelf (−25 m) to the shelf break (−55 m). The analysis of the 2D seismic data indicated that high-angle faults, formed under a strike-slip tectonic regime, primarily affected the Middle Miocene deposits beneath the shelf valleys. The formation of “negative flower pattern structures” was identified as a primary structural mechanism that contributed to SV formation. Reactivation events that occurred from the Late Cretaceous onwards, gave rise to these faults, which control SV formation and the capture of preterit drainage on the exposed continental shelf. The SV geometries display straight patterns and abrupt changes in direction (90°) due to the interplay of the NE-SW and NW-SE aligned faults. The results reinforce the importance of considering tectonic activity in the formation and evolution of shelf valleys. periods (SVs features magnetometry positioning D postrift post rift columncontrolled column controlled multidata multi −25 25 (−2 m −55 55 (−5 m. . highangle high angle strikeslip strike slip regime negative onwards 90° 90 (90° NESW NE SW NWSE NW SE −2 2 (− −5 5 9 (90 − ( (9

ABSTRACT This article aims to analyze the persistence of practices deeply rooted in the Chilean civic-military dictatorship, which delineate a distinctive dynamic in the relationship between the State and the population in contexts of social tension, particularly during demonstrations. Through a case study focused on the forestry workers' strike in Horcones in 2007, where Rodrigo Cisterna Fernández lost his life, and other workers were injured by the police, we seek to reconstruct the events. The analysis is primarily based on judicial documents associated with the case, unraveling the arguments presented by the Military Justice to legitimize institutional actions. These arguments reveal a persistent perspective in which the State defends itself against the citizenry, indicating the continuity of the National Security Doctrine (NSD) within the institutional structure. This study aims to contribute to understanding the complex interactions between the State and civil society in moments of tension, promoting reflection on the need for institutional reforms that foster a more equitable and respectful relationship toward human rights.

RESUMEN Este artículo se propone analizar la persistencia de prácticas arraigadas en la dictadura cívico-militar chilena, las cuales delinean una particular dinámica en la relación entre el Estado y la población en contextos de tensión social, especialmente durante manifestaciones. A través de estudio de caso centrado en la huelga de obreros forestales en Horcones durante el año 2007, en la que falleció Rodrigo Cisterna Fernández y otros trabajadores resultaron heridos a manos de carabineros, se busca reconstruir los acontecimientos. El análisis se fundamenta principalmente en los documentos judiciales asociados al caso, desentrañando los argumentos presentados por la Justicia Militar para legitimar las acciones institucionales. Estos argumentos revelan una visión persistente en la que el Estado defiende a sí mismo frente a la ciudadanía, denotando la continuidad de la Doctrina de Seguridad Nacional (DSN) en la estructura institucional. El presente estudio busca contribuir a la comprensión de las complejas interacciones entre el Estado y la sociedad civil en momentos de tensión, promoviendo una reflexión sobre la necesidad de reformas institucionales que fomenten una relación más equitativa y respetuosa de los Derechos Humanos.
