Evolution of the highly successful and multidrug resistant clone ST111 in Pseudomonas aeruginosa involves serotype switching from O-antigen O4 to O12. How expression of a different O-antigen serotype alters pathogen physiology to enable global dissemination of this high-risk clone-type is not understood. Here, we engineered isogenic laboratory and clinical P. aeruginosa strains that express the different O-antigen gene clusters to assess the correlation of structural differences of O4 and O12 O-antigens to pathogen-relevant phenotypic traits. We show that serotype O12 is associated with enhanced adhesion, type IV pili dependent twitching motility, and tolerance to host defense molecules and serum. Moreover, we find that serotype O4 is less virulent compared to O12 in an acute murine pneumonia infection in terms of both colonization and survival rate. Finally, we find that these O-antigen effects may be explained by specific biophysical properties of the serotype repeat unit found in O4 and O12, and by differences in membrane stability between O4 and O12 expressing cells. The results demonstrate that differences in O-antigen sugar composition can affect P. aeruginosa pathogenicity traits, and provide a better understanding of the potential selective advantages that underlie serotype switching and emergence of serotype O12 ST111.
Molecular characterization of the permanent outer-inner membrane contact site of the mitochondrial genome segregation complex in trypanosomes
Authors: Stettler Philip , Schimanski Bernd , Aeschlimann Salome , Schneider André
Published: December 2024

The parasitic protozoan Trypanosoma brucei has a single unit mitochondrial genome linked to the basal body of the flagellum via the tripartite attachment complex (TAC). The TAC is crucial for mitochondrial genome segregation during cytokinesis. At the core of the TAC, the outer membrane protein TAC60 binds to the inner membrane protein p166, forming a permanent contact site between the two membranes. Although contact sites between mitochondrial membranes are common and serve various functions, their molecular architecture remains largely unknown. This study elucidates the interaction interface of the TAC60-p166 contact site. Using in silico, in vitro, and mutational in vivo analyses, we identified minimal binding segments between TAC60 and p166. The p166 binding site in TAC60 consists of a short kinked α-helix that interacts with the C-terminal α-helix of p166. Despite the presence of conserved charged residues in either protein, electrostatic interactions are not necessary for contact site formation. Instead, the TAC60-p166 interaction is driven by the hydrophobic effect, as converting conserved hydrophobic residues in either protein to hydrophilic amino acids disrupts the contact site.

The testis is a reservoir for viruses that can cause persistent infection and adversely affect male reproductive health, an observation commonly attributed to deficiencies in inducible antiviral defence mechanisms. In this study, we demonstrate that interferon-epsilon (IFNε), a type I interferon initially discovered in female reproductive epithelia, is constitutively expressed by meiotic and post-meiotic spermatogenic cells, Leydig cells and macrophages in mouse testes. A similar distribution pattern was observed in human testes. Mice lacking IFNɛ were more susceptible to Zika virus-induced inflammation and damage of the testis and epididymis compared to wild-type mice. Exogenous IFNε treatment reduced the viral infection burden in cultured human testicular cells by inducing interferon-stimulated gene expression, and reducing inflammatory gene expression and cell damage. Treatment was more effective when administered prior to infection. These data indicate a critical role for constitutively-expressed IFNɛ in limiting viral infection and inflammatory damage in the male reproductive tract.
Vibrio cholerae RbmB is an α-1,4-polysaccharide lyase with biofilm-disrupting activity against Vibrio polysaccharide (VPS)

Many pathogenic bacteria form biofilms as a protective measure against environmental and host hazards. The underlying structure of the biofilm matrix consists of secreted macromolecules, often including exopolysaccharides. To escape the biofilm, bacteria may produce a number of matrix-degrading enzymes, including glycosidic enzymes that digest exopolysaccharide scaffolds. The human pathogen Vibrio cholerae assembles and secretes an exopolysaccharide called VPS (Vibrio polysaccharide) which is essential in most cases for the formation of biofilms and consists of a repeating tetrasaccharide unit. Previous studies have indicated that a secreted glycosidase called RbmB is involved in V. cholerae biofilm dispersal, although the mechanism by which this occurs is not understood. To approach the question of RbmB function, we recombinantly expressed and purified RbmB and tested its activity against purified VPS. Using a fluorescence-based biochemical assay, we show that RbmB specifically cleaves VPS in vitro under physiological conditions. Analysis of the cleavage process using mass spectrometry, solid-state NMR, and solution NMR indicates that RbmB cleaves VPS at a specific site (at the α-1,4 linkage between D-galactose and a modified L-gulose) into a mixture of tetramers and octamers. We demonstrate that the product of the cleavage contains a double bond in the modified guluronic acid ring, strongly suggesting that RbmB is cleaving using a glycoside lyase mechanism. Finally, we show that recombinant RbmB from V. cholerae and the related aquatic species Vibrio coralliilyticus are both able to disrupt living V. cholerae biofilms. Our results support the role of RbmB as a polysaccharide lyase involved in biofilm dispersal, as well as an additional glycolytic enzyme to add to the toolbox of potential therapeutic antibacterial enzymes.
SARS-CoV-2 Omicron variations reveal mechanisms controlling cell entry dynamics and antibody neutralization
Authors: Qing Enya , Salgado Julisa , Wilcox Alexandria , Gallagher Tom
Published: December 2024

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is adapting to continuous presence in humans. Transitions to endemic infection patterns are associated with changes in the spike (S) proteins that direct virus-cell entry. These changes generate antigenic drift and thereby allow virus maintenance in the face of prevalent human antiviral antibodies. These changes also fine tune virus-cell entry dynamics in ways that optimize transmission and infection into human cells. Focusing on the latter aspect, we evaluated the effects of several S protein substitutions on virus-cell membrane fusion, an essential final step in enveloped virus-cell entry. Membrane fusion is executed by integral-membrane “S2” domains, yet we found that substitutions in peripheral “S1” domains altered late-stage fusion dynamics, consistent with S1-S2 heterodimers cooperating throughout cell entry. A specific H655Y change in S1 stabilized a fusion-intermediate S protein conformation and thereby delayed membrane fusion. The H655Y change also sensitized viruses to neutralization by S2-targeting fusion-inhibitory peptides and stem-helix antibodies. The antibodies did not interfere with early fusion-activating steps; rather they targeted the latest stages of S2-directed membrane fusion in a novel neutralization mechanism. These findings demonstrate that single amino acid substitutions in the S proteins both reset viral entry—fusion kinetics and increase sensitivity to antibody neutralization. The results exemplify how selective forces driving SARS-CoV-2 fitness and antibody evasion operate together to shape SARS-CoV-2 evolution.

Everything We Have Done is Weather Now
Authors: Hirmer Lisa
Published: December 2024

Drawing loosely from a recent exhibition of the same name curated by Josephine Mills, Everything We Have Done is Weather Now, shares a collection of works by artist Lisa Hirmer that explore changing human relationships with weather, particularly as it entangles with lived experiences and understandings of climate change. Climate change is of course often associated with dramatic weather events and disruptions of seasonal norms; at the same time daily weather is often a site for locating and making sense of the material and cultural conditions of climate change. The photo-based works in this piece consider the ways in which climate change is registered, understood, shared, recorded through weather. The essay also considers how the works (which span from 2016-2022) act as a personal record of how understandings of climate change have themselves shifted alongside the rapidly changing climate.

Relative Humidity: Reuniting the Disciplines of Museological and Ecological Conservation
Authors: Cadotte Emily
Published: December 2024

This article considers the concept of conservation from both a museological and ecological lens, locating its modern origins in the development of the mechanical hair hygrometer invented by Horace Bénédict de Saussure. Loosely employing the sociological method of a field study, the paper finds that ecological conservation and art/museum conservation not only share an origin but have begun to collapse back in on themselves in the face of climate change, where land art has become a “barometer” for rapidly changing ecosystems and protected living species have begun to be monitored with the exacting practices normally reserved for museum collections. It concludes with the arbitrary nature of what has the privilege—or burden—of being conserved, in relation to semiotic analysis (the arbitrary nature of the sign) developed by de Saussure’s Senior’s great-grandson, Ferdinand de Saussure.

Cloud-Scale Uncertainties
Authors: Beeferman Leah
Published: December 2024

Clouds are a main source of uncertainty in climate change. Clouds cast shadows as they pass, shadows which are, perhaps, a metaphor for what is (or can be) known and what is not (or cannot be). Scientists study clouds, the forest, and weather—and make images of them in the process—to understand how climate change may affect them in the future. And they must: they need better models for weather prediction to address our cloud- (or climate-) scale uncertainty. However, landscapes, and weather, defy representation. So, when do images help find certainty within uncertainty, and when do they prolong or maintain it? For me, as an artist, images keep questions open as much as they answer them. Even an image made as an answer can hold innumerable other answers and questions—not as a tool to dispute facts but to magnify potential, and to open up space for thought.

Non-Governmental Organizations as a Platform for Social Inclusion: Experiences of the Social Connectedness of People With Disabilities
Authors: Beneševičiūtė Irmina
Published: December 2024

The article examines the importance disabled people award to NGOs in their experiences of social connectedness. Applying qualitative research methods (interviews and content analysis) revealed significant aspects of the existential desire to belong to a group. Four research categories emerged: connectedness through identity, connectedness with another person, connectedness through the need to give help, and connectedness through the need to receive help. The results of the research showed that disabled people join NGOs when they feel rejected by society. This involves a step in the search for one’s own identity in order to realise oneself as a person. The research revealed that people with disabilities may look for people with the same fate, giving meaning to their lives and being. The category of connectedness with another person revealed that communication is an integral part of social connectedness. This leads to overcoming loneliness, not being closed at home, and having human relations with each other within an NGO. Based on the results of the qualitative research, it became clear that in terms of connectedness through the need for help, it was considered important to help others and for NGOs to be interested in those who need help. From the data that were obtained during the research, it can be seen that moral support and psychological help are important components of connectedness for seriously ill individuals.
Pushing the Boundaries or Pulling the Norms: An Exploratory Study on the Cases of ‘Child Marriages’ in Turkiye
Authors: Yüksel Hasan
Published: December 2024

From the perspectives of the interviewees, this research studies the role of ‘traditions’ in child marriage as a social and cultural phenomenon in Turkey. This exploratory study focuses on the ‘narratives’ of a group of Turkish women who married in their childhood. These sorts of marriages are one of the hot topics of sociology and social policy as an interdisciplinary academic field. There has been a profound change concerning attitudes towards marriages over the last years: even for those from conservative families, there is no hesitation in saying that ‘culture’ and ‘norms’ radically shaped marriages in the past, resulting in a child or early marriage. As stated, the results suggest that marriage patterns have been changing radically. This shift from past to present concerning marriage patterns results from many parameters like technological progress, improvements in education, social media, urbanization, the usage of popular culture outlets such as TV programs, talk shows, documentaries, platforms like Netflix, Disney Plus, and so on. However, early marriage still occurs in particular regions of the country. The present study details the outcomes of qualitative research conducted in Turkey on respondents who married when they were children. It demonstrates that cultural factors played a certain role in these sorts of marriages. The snowball technique was applied to identify the interviewees, and thematic and content analysis were utilized to analyze the qualitative data. As a result of the research, four categories and ten themes correlated with child marriage were verified.
Breve Histórico e Fundamentos da Análise Bioenergética
Authors: Pacheco Maria Eniana Araújo Gomes , Oliveira Gislene Farias de
Published: December 2024

A análise bioenergética é uma terapia que une o trabalho do corpo e das emoções para melhorar a saúde mental e física. Desenvolvida por Alexander Lowen, essa perspectiva se inspirou nas teorias de Wilhelm Reich que enfatiza a relevância do corpo físico e também da energia vital no campo da psicoterapia. Reich foi um seguidor de Freud que postulava a importância da energia vital conhecida como “orgone” para a saúde global do indivíduo. Argumentava que as emoções reprimidas poderiam obstruir o seu fluxo repercutindo em questões, tanto mentais quanto físicas. Na década de 1950, Lowen ampliou esses conceitos ao combinar técnicas corporais com psicanálise para auxiliar os pacientes na liberação de tensões e emoções reprimidas. Ele enfatizava que corpo e mente estão entrelaçados. Os princípios fundamentais da análise bioenergética incluem o fluxo positivo da energia vital através do corpo para garantir bem-estar; bloqueios nesse fluxo poderiam resultar em problemas emocionais e físicos. Além disso, as tensões musculares são interpretadas como expressões de emoções guardadas, tornando-se crucial identificá-las e liberá-las.  Essas pressões podem levar a dores e dificuldades emocionais para alguns indivíduos. Para aliviar essas tensões e promover o bem-estar geral das pessoas, são propostas técnicas de relaxamento, que incluem exercícios respiratórios e, movimentos corporais associados à expressão vocal, além de toques terapêuticos. Na análise bioenergética é valorizada a capacidade de se expressar com autenticidade as emoções, como um aspecto essencial para a saúde mental. O uso de exercícios corporais e intervenções psicológicas auxiliam os indivíduos no desbloqueio de suas emoções. A interconexão entre o corpo e mente é crucial nessa abordagem, dado que problemas físicos frequentemente têm raízes em traumas emocionais. Conclui-se, pois, que a terapia visa abordar o ser humano de forma integral, promovendo o desbloqueio por meio de diversas técnicas. Enfim, a análise bioenergética integra corpo e mente visando à cura e ao bem-estar, tornando-se uma abordagem significativa na psicoterapia atual.
A Conexão entre Corpo e Mente segundo Wilhelm Reich
Authors: Lopes Raimundo Edilberto Moreira , Almeida André Luiz Barros , Vidal Eglídia Carla Figueiredo
Published: December 2024

Durante a história da psicologia e das ciências da saúde, tem havido um interesse crescente na ligação entre o corpo e a mente. Wilhelm Reich foi uma figura pioneira que explorou essa conexão, vendo o corpo como um reflexo das emoções humanas. Ele desenvolveu técnicas corporais para aliviar as tensões internas e restaurar o equilíbrio e a serenidade do ser humano. Sua teoria sobre energia vital é usada até hoje. Reich discordou de algumas das ideias de Freud e concentrou-se nas dimensões corporais da mente, particularmente na libido e na energia sexual. Ele acreditava que a repressão sexual causava problemas mentais e que a sociedade impunha obstáculos emocionais. Reich enfrentou controvérsias e perseguições políticas, com seus livros sendo apreendidos. Apesar de sua morte em 1957, sua influência persiste na terapia corporal da análise bioenergética.

INTRODUCTION:

Patients with pancreatic ductal adenocarcinoma (PDAC) face challenging treatment decisions following their diagnosis. We developed and validated a survival prognostication model using routinely available clinical information, patient-reported symptoms, performance status, and initial cancer-directed treatment.

METHODS:

This retrospective cohort study included patients with PDAC from 2007 to 2020 using linked administrative databases in Ontario, Canada. Patients were randomly selected for model development (75%) and validation (25%). Using the development cohort, a multivariable Cox proportional hazards regression with backward stepwise variable selection was used to predict the probability of survival. Model performance was assessed on the validation cohort using the concordance index and calibration plots.

RESULTS:

There were 17,450 patients (49% female) with a median age of 72 years (interquartile range 63–81) and a mean survival time of 9 months. In the derivation cohort, 1,469 patients (11%) had early stage, 4,202 (32%) had advanced stage disease, and 7,417 (57%) had unknown stage. The following factors were associated with an increased risk of death by more than 10%: tumor in the tail of the pancreas; advanced stage; hospitalization 3 months before diagnosis; congestive heart failure or dementia; low, moderate, or high pain score; moderate or high appetite score; high dyspnea and tiredness score; and a performance status score of 60–70 or lower. The calibration plot indicated good agreement with a C-index of 0.76.

DISCUSSION:

This model accurately predicted one-year survival for PDAC using clinical factors, symptoms, and performance status. This model may foster shared decision making for patients and their providers.

Aktionsräume temporär Wohnender in deutschen Städten: Das Zusammenspiel von Alltagsorten und Wohlfühlorten
Authors: Willecke Maya
Published: December 2024

Increasing mobilities, individualisation and flexibilisation of life, as well as temporary work arrangements, lead to residential and living arrangements that are not conceived as permanent but often as temporary. The everyday life of people living temporarily in cities differ from that of permanent residents, as it is associated with limited stays, presences, and absences. Activity spaces, understood as the set of all locations which the individual uses in day-to-day activities, offer a useful opportunity to explore the everyday lives of temporary residents. This paper uses narrative interviews and a cognitive map to investigate the activity spaces of temporary residents in the two German city regions Frankfurt am Main and Leipzig. The qualitative study focuses on activities, interactions and constraints associated with the respective everyday places. In addition, an emotional aspect is considered, that is conceptualised through places of well-being and provides insights into senses of belonging. A typification of temporary residents’ activity spaces reveals that places of well-being in particular should be given more attention in the future, as they significantly influence a feeling of being at home in the city.
Tajemnice i poszukiwanie bezpieczeństwa. O sposobach utraty tajemnic i nadziejach na ich odzyskanie. Część I
Authors: Szulakiewicz Marek
Published: December 2024

Mysteries have appeared in many areas of past culture as one of the prerequisites for asking about the world. However, the old forms of their appearance and the philosophers’ (Heidegger’s) dreams of the necessity of returning to them belong to the past. The article attempts to answer the question of the meaning of mystery in our culture, philosophy and religion. It characterises the social and metaphysical dimensions of the secret and contrasts secret and mystery. In metaphysical terms, the secret refers to the way in which the world and man exist, and not to a lack of knowledge. In it (and through it) the world appears as not complete, not fulfilled, not finished and always unfinished, but open to new possibilities. The text also shows and discusses the processes of demystification and their consequences for man and culture. The last section of the article shows areas in which the hope for a restoration of culture has remained. These are religion and science. In its essential aspect, religion is naturally interwoven with mystery. Modern science also takes a “step back” in the face of a soulless and objectified reality. It maximises the role of the cognitive subject and minimises the objectification of the world.
Copies vs Originals in Hittite
Authors: Sideltsev Andrei V.
Published: December 2024

This paper is a case study of how the material of copies and originals correlate for a concrete fragment of Hittite grammar – clitic reduplication, double use of the same clitic within the same enclitic chain. It is argued that whereas in part of the copies there is non-trivial interaction of the grammar of the pre-New Hittite original with the grammar of the New Hittite scribe, the data of the copies is relevant and it does represent a real linguistic usage. Thus, copies are reliable as linguistic evidence, unless explicitly shown to be otherwise.
Investigating the influence of plate geometry and detonation variations on structural responses under explosion loading: A nonlinear finite-element analysis with sensitivity analysis

Published: December 2024

This study presents the results of a numerical analysis of the response of Domex 700 and Dormex 1100 steel plates with varying geometries, combined with several different parameters such as a thickness of up to 6 mm and a trinitrotoluene (TNT) mass. Using ABAQUS software, finite-element analysis was run to examine the structural response ability of the steel plates to explosions. In terms of deformation and energy dissipation, the results showed a large differentiation. A sensitivity analysis was used to examine each simulation result in terms of the structural response performance to explosions and identify the variables that had the greatest impact on variations in the thickness, material, geometry, and TNT mass. The best numerical simulation results were found using the multi-attribute decision-making (MADM) approach. Annotations are utilized to assist in identifying the various modifications made during testing. Annotations LXXI to LVIII achieved the lowest value of 6.176 × 10−09, signifying the best results according to calculations made using the MADM approach. This is evidenced by the structural events, demonstrating that the deformation, von Mises stress, and energy dissipation in the circular plate structure were not significantly impacted by the explosion. The variables that most significantly affect variations in deformation, von Mises stress, and dissipated energy – variables that significantly impact the structural response to explosions – are identified through the sensitivity analysis approach. The results of this research can be used to optimize the structural response performance of circular plates.

Rock-Cut Monuments at Macedonian Philippi – Taking Image Analysis to the Religioscape
Authors: Graml Constanze , Diosono Francesca , Hunziker Manuel
Published: December 2024

The massive amount of rock-cut monuments along the slopes of the acropolis hill of Philippi in ancient Macedon has received scholarly attention since the first expeditions and following excavation and research campaigns conducted by the French School at Athens in the nineteenth century. The documentation of these peculiar monuments, comprising images in relief, etchings, inscriptions, and empty niches, consists of very few early drawings, photographs of single objects and sometimes of clusters of neighboring monuments, maps documenting the monuments’ location along the slopes of the acropolis rock (intra and extra muros) and brief descriptions leading to an iconographical categorization. Despite a variety of subjects, the depiction of a youthful huntress commonly denominated as Artemis/Diana is predominating. Based on the commonly accepted dating of these reliefs to the Roman era, the rock-cut monuments are generally interpreted as expressions of popular religion that went unregulated by the state; some even consider them as evidence for specifically female ritual practice. As part of the project “Rock-cut reliefs in Philippi: a microregional study on the religion of ancient Macedon,” a first on-site documentation campaign was carried out in March 2023. The presented case study of the rock-cut reliefs from Philippi aims at spatializing the religiously connotated depictions within the city-/landscape as a first step and applying the concept of religioscape. With this approach, it differs in the methodology used so far, namely the iconographical analysis of the objects as a first analytical step. This article at hand presents the method used to establish the first three-dimensional data sets of the reliefs for documenting as well as monitoring their condition and aims to demonstrate the immense value of these 3D models given the dangers natural corrosion and vandalism pose to the archaeological objects. Moreover, embracing the ability to capture the landscape setting in 3D allows us to visualize the three-dimensional embedding of the objects into the urban fabric of the city with its varied terrain profile. This allows for new analytical prospects, such as inter-visibility, reachability, or building economy.

-haltigen Determiniererflexion im Genitiv Singular Maskulinum und Neutrum
Authors: Hübener Carlotta J. , Szczepaniak Renata
Published: December 2024

This paper examines the variation between -n and -s in the genitive singular inflection of determiners for masculine and neuter nouns as can be observed in Herbst diesen Jahres vs. Herbst dieses Jahres ‘autumn of this year’. So far, the discussion of this phenomenon has focused on the demonstrative determiner dies-, where the -n inflection is regarded as a new, non-standard variant. The results of our corpus study of newspaper texts show that the -n inflection occurs across the entire determiner system and is supported by the decreasing prototypicality of individual determiners: the less prototypical a determiner is, the more frequently it exhibits the -n inflection. The least prototypical determiner class is formed by indefinite determiners such as jed-, which predominantly exhibit -n inflection (e. g., Menschen jeden Alters). The majority of demonstratives fulfil the prototypical features of determiners. Here, the -n inflection represents a rare variant of the -s inflection. Finally, possessive determiners are located in the prototypical centre of the determiners and consistently exhibit -s inflection with a few exceptions. Our study also shows that genitive noun phrases introduced by determiners exhibiting -n inflection have less paradigmatic depth and block adjectival attribution. Although the contexts in which -n occurs are restricted, it is always interchangeable with -s. We therefore classify these two forms as allomorphs.

-Adjektive als neues Wortbildungsmuster im Deutschen
Authors: Schlücker Barbara
Published: December 2024

Adjectives with the borrowed head constituent like are a previously undescribed phenomenon in German. This corpus-based study shows that they occur frequently in certain text sources and analyses them as a productive word-formation pattern. The article describes the morphological, syntactic, graphemic, semantic, and pragmatic properties of these adjectives. While their structural formation is subject to only few constraints, their use is much more restricted. This is shown, among other things, by the frequent use of quotation marks which indicates that writers are aware of the novelty or expressiveness of the formations. Finally, the emergence of the pattern in German is discussed in terms of foreign word-formation vs. grammatical borrowing.
Die RUEG-Korpora: Ein Blick auf Design, Aufbau, Infrastruktur und Nachnutzung multilingualer Forschungsdaten
Authors: Klotz Martin , Hartz Rahel Gajaneh , Labrenz Annika , Lüdeling Anke , Shadrova Anna
Published: December 2024

The article presents the RUEG corpora. We begin by describing the basic principles and research questions, that influenced and shaped the corpora and introduce the method of data generation. We proceed by describing the fundamental components of the building process and the overall outcome. Said outcome provides interfaces for new researchers, who wish to conduct their own research using the RUEG corpora. Options for such research are discussed by showing that it can succeed within the range of re-using exisiting annotations and metadata up to building entirely new, but comparable corpora.

Resistências: do embrião ao clímax do fim da escravidão no Brasil e no mundo
Authors: Vieira Willian Marcio Barbosa
Published: December 2024

“(...) Os processos que levaram ao ‘fim da escravidão’ são muito menos conhecidos e frequentemente relegados ao final das obras consagradas à escravidão em si” (DORIGNY, 2019, p. 14). Com efeito, a obra As abolições da escravatura no Brasil e no mundo, escrito por Marcel Dorigny, do Departamento de História da Universidade Paris-VIII na França, e publicado pela Editora Contexto em 2019, apresenta aspectos primordiais que influenciaram as manifestações contrárias à escravidão, instituída por vários séculos no mundo. Não obstante àquilo que a maioria das pessoas aprenderam e consideram como movimentos que proporcionaram o fim da escravidão, como o desenvolvimento da indústria, a ampliação do mercado consumidor ou a influência dos ideais do Iluminismo, o autor enfatiza que estes não foram únicos. Os movimentos realizados pelos próprios escravos, chamados por ele de resistências e revoltas, ainda nos oceanos, também contribuíram para o processo abolicionista.
“Urge uma reação contra a esquerda”: a intervenção da imprensa na reorganização do movimento sindical no Rio de Janeiro (1950-1954)
Authors: Silva Lins Artur
Published: December 2024

Neste artigo busco destacar e avaliar o grau de poder da influência da imprensa empresarial sobre a reorganização do movimento sindical na cidade do Rio de Janeiro entre 1950 e 1954. Tal intervenção na realidade dos sindicatos parte da historicidade de uma conjuntura em que a retomada da mobilização sindical ocorreu num momento em que a imprensa empresarial carioca, através da modernização de sua atividade, potencializa sua autorrepresentação enquanto uma força social mediadora, privilegiada e eticamente comprometida com os interesses dos próprios trabalhadores e de seu movimento organizado, já que se ampliava nessa relação a politização ativa e a visibilidade pública dessas camadas sociais, sobretudo a inserção das esquerdas trabalhista e comunista nesses espaços.Palavras-chave: imprensa; movimento sindical; trabalhismo; comunismo. AbstractIn this article I seek to highlight and assess the degree of power of the influence of the business press on the reorganization of the union movement in the city of Rio de Janeiro between 1950 and 1954. This example of press intervention is part of the historicity of a situation in which the resumption of union mobilization occurred at a time when the Rio’s business press, through the modernization of its activity, enhances its self-representation as a mediating, privileged and ethically committed social force to the interests of the workers themselves and their organized movement, as it expanded in this relation the active politicization and public visibility of these social layers, especially the insertion of the Labor and communist left in these union spaces.Keywords: press’s history; union movement; Brazilian Labor’s Party; communism.

Este trabalho busca analisar a escravidão marítima sediada na Cidade de Rio Grande nas últimas décadas de vigência da instituição servil. Valendo-se de um auto criminal ocorrido em 1873, procura-se demonstrar o conjunto de relações sociais, poder e trabalho no qual marujos escravizados estavam imersos. Especificamente, este texto se debruça sobre dois aspectos principais: a escravidão marítima e sua capacidade de produzir cesuras na solidariedade de classe dos marinheiros; e a aplicação do castigo sobre marujos escravizados da marinha mercante e a postura dos envolvidos diante dessa prática. Ademais, este artigo visa observar a resistência daqueles sujeitos às situações de dominação e violência que lhes atravessavam, investigando as formas de contestação maruja à escravidão e ao trabalho marítimo.Palavras-chave: Escravidão; Cultura marítima; Rio Grande; Processo criminal. AbstractThis work seeks to analyze the maritime slavery situated in Rio Grande city in the last decades of the servile institution's existence. Based on a criminal case which occurred in 1873, it seeks to demonstrate the set of social relations, power, and work in which enslaved sailors were immersed. Specifically, this text focuses on two main aspects: the maritime slavery and its capacity to produce ruptures in the sailor's solidarity class; and the application of punishment on enslaved sailors of the merchant marine, regarding the practice itself and the attitude of those involved in it. Furthermore, this article aims to observe the slaves' resistance to the situations of domination and violence that were imposed on them, investigating the forms of objection to slavery and maritime labor.Keywords: Slavery; Maritime culture; Rio Grande; Criminal case.
