Arachne: Weaving and the Origin of Technè in the Renaissance
Authors: Koering Jérémie
Published: March 2024

During the Renaissance, the spider, as well as its mythological double Arachne, came to represent a form of technical exemplarity doubled by a form of practical intelligence. Some artists, such as Joris Hoefnagel and Tintoretto, made the spider a figure of artistic subtlety, allowing them to situate art in an intertwining of making and thinking. But how could the activity of an insect become an artistic paradigm? What imaginaries could have favored this assumption? Under what conditions could a figure as vile and disturbing as the spider or as negative as its mythological double Arachne be set up as examples to follow? This essay attempts to answer these questions by bringing together mythological representation, emblematic thought, and natural philosophy.
Heinrich Wölfflin’s Classic Patterns of the Renaissance
Authors: Tauber Christine
Published: March 2024

This essay examines Heinrich Wölfflin’s patterns of judgement in his pioneering art-historical study Classic Art, first published in 1899. By using the anti-historicist concept of the “classic”, he systematically withdraws the art of the High Renaissance from historical change in order to erect it as a protective shield against the transience of unclassic modernism and contemporary life. This proto-structuralist act of creating order by means of pattern comparisons in the timeless realm of beauty conceives the art historian as both an intellectual aristocrat with artistic ambitions and a conservator of the eternities of classic art.

Published: March 2024

Esse trabalho é resultado da pesquisa realizada na área interfluvial dos rios Guaporé e Carreiro, localizada na região nordeste do Rio Grande do Sul. A área foi alvo de pesquisas arqueológicas realizadas no início da década de 1970, e com breves incursões no início dos anos 2000. O objetivo deste artigo é apresentar a investigação sobre a presença da cultura material de grupos antigos na região, denominados povos indígenas. Considera-se a potencialidade da história indígena dessas antigas ocupações humanas na região e com isso realizou-se a identificação dos pontos de interesse arqueológico com a presença de vestígios materiais entre os rios citados. A metodologia aplicada baseou-se na localização e registro das áreas a partir de modelos de parâmetro locacional e atividades de prospecção. Como resultados finais, foram identificadas 23 áreas com a presença de vestígios materiais. A variabilidade dos padrões ambientais onde os pontos estão localizados, somados à tecnotipologia dos artefatos demonstra a presença de diferentes grupos humanos e de diferentes estratégias de assentamentos.

Análise estrutural das brincadeiras de boi
Authors: Seraphim Yves Marcel
Published: March 2024

O artigo investiga como as brincadeiras de boi no Brasil significam as qualidades sensíveis presentes nos comportamentos e nos artefatos de seus rituais. Para tanto, realiza-se uma análise estrutural em que as brincadeiras são estudadas como mitos, o que, por sua vez, implica revisitar a perspectiva lévi-straussiana de estudo dos mitos bem como da relação entre rito e mito. A fim de explorar características pouco notadas das versões das brincadeiras, o artigo expõe variações sulistas, chamadas boi-de-mamão e identifica relações significativas com variações mais conhecidas, como bumba-meu-boi e boi bumbá. Com base nesses dados, o encadeamento entre vida, morte e ressureição do boi é visto pelo prisma do código corporal, o qual é miticamente tematizado por meio da dinâmica entre os atravessamentos digestivo (para o boi) e gestatório (para personagens femininas e seus bebês).
“A gente aprende olhando os outros”:

Published: March 2024

As lidas campeiras caracterizam-se por um conjunto de práticas relacionadas ao abate de animais, sendo compostas por diversos ofícios, dentre eles a carneada, processo de abate e transformação de animais em alimento e artefatos a partir do couro, lã e ossos. Com base em estudo etnográfico sobre a carneada de ovelhas no município de Jaguarão, Rio Grande do Sul, este artigo busca refletir sobre a aprendizagem deste ofício, composto por uma série de técnicas para transformação das ovelhas em carne. Conforme Marcel Mauss, o corpo é o primeiro objeto e instrumento técnico dos seres humanos e aprender uma técnica faz parte da educação do corpo, influenciada por práticas e modos de vida. A partir da abordagem de Ingold (2010) de uma “educação da atenção”, pode-se dizer que o carneador aprende a carnear na companhia de outros carneadores, dos animais e pela experiência nas lidas campeiras. É a partir de relações de observação, convívio com as lidas e com as ovelhas antes do abate que os carneadores aprendem a exercer uma carneada bem-sucedida, assim considerada aquela em que o animal morre rapidamente e que produz uma carne de boa qualidade. Investigar os processos de aprendizagem da carneada de ovelhas é o objeto principal deste artigo.
The Structural Characterisation of Fibre Networks in Papermaking Processes – A Review
Authors:   Department of Paper Science, UMIST, PO Box 88, Manchester, M60 1QD, UK, Sampson W.W.
Published: March 2024

The literature concerning the structure of two- and three- dimensional fibre networks is reviewed. Emphasis is placed on the literature concerning such networks in papermaking processes, though examples are drawn from other systems. The propensity of a suspension to flocculate is considered from a theoretical viewpoint. The experimental techniques and structural descriptors applied in the characterisation of fibre networks are discussed. Theoretical studies of random networks are presented along with their use as reference structures and comparison is made between the main techniques used in the structural characterisation of essentially two-dimensional networks such as paper. The relationships between the distributions of mass and voids are examined and the dependence of sheet nonuniformity on that of the suspension from which it is formed is reviewed.

Two model fines, representing microfibrils and microgranules, and two fractions of TMP fines were used to demonstrate their effect on tensile strength and optical properties of handsheets formed from TMP and kraft fibers. The model microfibrils behave as a binder between fibers, thus improving tensile strength. The light scattering of kraft handsheets decreases but that of TMP handsheets increases. The model microgranules behave as a pigment by improving light scattering but preventing interfiber bonding. TMP fines, containing both types are capable of increasing tensile strength and light scattering simultaneously. The relation between tensile strength and light scattering depends on the proportion of fibrillated fines and granulated fines. The fractionated TMP fines of high surface area are shown to be very effective in improving the handsheet properties and the relation between tensile strength and light scattering is superior to that achieved by calcium carbonate filler.

The stress-strain performance of 2D and 3D cellulose fibre networks was simulated using a network model. A model network consists of bonded curled fibres placed at random in a cell. The bonds show a stick-slip fracture behaviour. Results concerning the influence of network density, fibre orientation and ductility of bonds on the stress–strain behaviour of a network are given, and an example of fracture localization is provided.

The mechanical properties of paper are impaired by the addition of filler. The beating of kraft pulp and addition of starch are possible remedies for this. However, beating also has negative effects because it reduces opacity and bulk, and starch effects are limited by retention. Optimal use of the kraft pulp and starch is therefore important. We show that in pure kraft sheets beating alone can compensate for most of the adverse effects on mechanical properties caused by kaolin addition. In TMP-based sheets with kaolin, the mechanical properties are fairly insensitive to the kraft content unless very high beating levels are used. The primary role of kraft is to improve tensile stiffness, not tensile strength of paper. Starch and beating both improve inter-fiber bonding but beating also raises fiber segment activation. The latter mechanism contributes to tensile stiffness but reduces damage width. The other mechanical properties of paper appear to be insensitive to fiber segment activation.

Web breaks in pressrooms have been modelled in terms of web strength variations and tension variations to identify principal factors controlling the pressroom performance. The web strength variations and their scaling law (the size dependence) have been formulated based on an extreme statistics approach, and the distribution parameters have been determined for a number of mechanical printing grades. By using the tension variation statistics data obtained from a pressroom trial, a parametric study has been conducted to examine the relative magnitude of the effects of key paper properties. The predictions have been compared with field study data. Among the conventional paper properties, tensile strength and elastic stretch consistently predicted the break frequency. The strength uniformity parameter (Weibull exponent) was shown to have the highest impact on the break frequency based on the parametric study.

The measurement of “damage width” from silicone-impregnated specimens reveals the area in which bond failures and other microscopic fractures take place. We demonstrate that damage width is a reasonable measure of the size of the fracture process zone in the sense of fracture mechanics. Firstly, the decay of cohesive stress against crack widening scales with damage width. Secondly, we can calculate the tensile strength of paper from fracture mechanics using damage width as the size of the fracture process zone. Armed with this interpretation, one can use damage width to evaluate, for example, the effective length and strength of fibers in paper.

Monsieur Pain, de Roberto Bolaño
Authors: De Almeida Rocha Wesley Thales
Published: March 2024

Este artigo aborda o romance Monsieur Pain, de Roberto Bolaño, analisando a combinação que nele é feita de elementos relativos à experiência real e histórica com os da dimensão ficcional e subjetiva. Na obra em questão, o narrador-protagonista, de nome Pierre Pain, conta a história de sua ligação com o caso médico de um homem latino-americano chamado “Vallejo”, cuja doença é desconhecida pelos médicos. Terapeuta mesmerista, Pain é chamado para colaborar no tratamento do enfermo, mas acaba ingressando em uma trama permeada de ameaças e mistérios, a qual envolve perseguições políticas relacionadas ao fascismo espanhol, traumas da Primeira Grande Guerra e prenúncios da Segunda, além de interlocuções entre práticas ocultistas e pesquisa científica. Como é comum em sua escrita, Bolaño explora, nesse romance, dimensões imaginárias e subjetivas da história, fazendo o real se erigir mais da repercussão dos eventos junto ao inconsciente do narrador-protagonista que dos fatos em si. Desse modo, o escritor chileno não simplesmente documenta e reconta a história, expondo-a tal como teria sido, como também não meramente a ficcionaliza, forjando uma outra realidade descolada da factual e vivida. Sua escrita, antes, penetrava nos labirintos da subjetividade, enquanto atravessados pelos da história e pelos do desconhecido, recolhendo os vestígios do vivido e lhes dando uma dimensão espectral. Com isso, ele revela o pathos incompreensível e incurável da experiência histórica. Articulando referências teóricas e críticas situadas entre a literatura e a psicanálise, este estudo procura examinar como, na narrativa de Bolaño, o real e o ficcional se interpenetram, primeiro na mente atormentada do protagonista e, depois, em sua narração, assim expondo os dilaceramentos subjetivos que marcam a experiência com a história.

Published: March 2024

This theoretical reflection article germinates from the need to generate theoretical constructs on the application of Pedagogy by Projects (PPP) as a tool for the development of educational practices, with the aim of showing alternatives to break with traditional training methods, revealing new active teaching methodologies that contribute to the acquisition of significant academic skills. The article was based on the reflective qualitative methodology, where integrative relationships were established in a coherent way between the results of an investigation culminated and grounded in the theory based on microanalysis, open coding, axial coding and selective coding. In addition, the following parameters are taken into account for the preparation of the writing: coherence, rigor, comprehension, predictive capacity, conceptual precision, linguistics, semantics and originality. As a main revelation, it can be mentioned that the training processes in Public Institutions of Medellin based on the PPP methodology are distant from what is stated in the general education law and the main theories that support it, such as meaningful learning and constructivism, in part because lack of appropriation and qualification of teachers on the subject. Likewise, it is relevant to affirm that there are not enough economic resources for the provision and adaptation of training establishments, which has a negative impact on the achievement of the objective. To conclude, the theory was accentuated in revalidating positive, true and real aspects of the PPP, and recommendations for teachers and educational institutions that want to include this work methodology in their curriculum and educational practices.

Authors: DAMILL MARIO
Published: March 2024

RESUMO Este artigo analisa a evolução recente do sistema monetário e financeiro da economia argentina, particularmente a partir da implantação do “Plano Austral”, em 15 de junho de 1985. O sistema financeiro é apresentado sob uma perspectiva de longo prazo, como resultado da duas reformas financeiras (1977 e 1982) cujas principais características determinaram a atual situação de fragilidade. O sistema monetário é analisado através do comportamento das principais agregações monetárias observando particularmente o caso da evolução dos diferentes tipos de ativos nas mãos das pessoas. Segundo o autor, o impacto inicial do plano de estabilização (“Plano Austral”) teve dois elementos que se destacaram: o aumento da demanda por recursos monetários e a redução do déficit fiscal.
A determinação do lucro em Kalecki: análise empírica dos Estados Unidos, 1947-1985*
Authors: SILVA EDNALDO ARAQUÉM DA
Published: March 2024

RESUMO Em contraste com a exegese usual encontrada na literatura, o modelo de lucro de Kalecki foi estimado usando dados anuais dos Estados Unidos entre 1947-1985. Assumindo uma defasagem de investimento de um ano, o modelo de Kalecki explica 96% da variação dos lucros brutos reais dos Estados Unidos no período analisado. De acordo com o multiplicador de lucro estimado, o aumento de um bilhão de dólares de 1982 no investimento real bruto (aumentado pelo governo e pelos déficits externos) aumentaria os lucros brutos reais em 1,1 bilhão de dólares e o consumo capitalista em 63,3 milhões de dólares. No entanto, o multiplicador de lucro estimado é bastante baixo quando comparado com a estimativa do próprio Kalecki para os EUA, durante a Grande Depressão.

Published: March 2024

RESUMO Há uma necessidade crescente de intervenção nas estruturas de concreto armado existentes para recuperar ou aumentar a sua capacidade resistente. O uso de materiais compósitos, como a fibra de carbono, tem sido eficiente, mas o custo ainda é um entrave. A aplicação de barras de aço como elemento de reforço apresenta-se como material alternativo e tecnicamente viável, porém existem poucos trabalhos na literatura. Desse modo, este trabalho realizou uma série experimental com três vigas de concreto armado sem armadura transversal, e reforçadas ao cisalhamento com barras de aço utilizando a técnica near-surface mounted (NSM). Foram monitorados no experimento a carga, o deslocamento e o padrão de fissuração. Os resultados demonstraram a eficiência do reforço com aumento de 69% da carga última e 63% da carga para surgimento das primeiras fissuras comparados a viga de referência. O reforço também aumentou a ductibilidade das vigas antes da ruptura brusca por cisalhamento. Modelos numéricos via método dos elementos finitos (MEF) foram realizados no software ABAQUS utilizando diferentes tipos de elementos e malhas. Os resultados numéricos foram validados com os resultados experimentais e foi observado que o uso de elementos quadráticos comparados a elementos lineares consegue representar melhor o padrão de fissuração e a capacidade de carga das vigas. A relação média dos resultados numérico/experimental para carga máxima das vigas reforçadas foi de 0,94.

Published: March 2024

ABSTRACT Mapping and classifying Coastal Wetlands is important for their conservation. The study aimed to apply Object-Based Image Analysis (OBIA) and pixel-based approaches to answer the questions: (1) which approach is more accurate for classifying Wetlands; (2) Sentinel 1A images improve the classification of Wetlands compared to Sentinel 2A; (3) dual-station sorting has greater potential for sorting Wetlands compared to single-station sorting. We used Sentinel 1 and 2 in single and double seasons (winter and summer) to classify a coastal UA in Rio Grande do Sul. The results show OBIA with greater potential, with accuracy greater than 80%. Sentinel 2 shows higher ranking importance compared to Sentinel 1. Dual season OBIA increased kappa by up to 7% compared to single season. Furthermore, the pixel-based dual season had lower kappa than the OBIA single season. We conclude that OBIA, even at a single station, has greater potential to map coastal AUs.

Quem disse que ser mulher é ser mãe? Feminilidade(s) e maternidade(s)
Authors: Santos Gisele Cerqueira , Galrão Paula da Luz , Sousa Lucivanda Cavalcante Borges de
Published: March 2024

Resumo A feminilidade na sociedade brasileira é compreendida como uma experiência destinada à vivência da maternidade, sendo este um caminho indispensável para a confirmação do ser mulher. Dessa maneira, existem mulheres que são marginalizadas a partir da negação do seu direito de escolher a construção da maternidade. Este estudo objetiva discutir as maternidade(s) das mulheres diante do processo de tornar-se mãe. Trata-se de um ensaio teórico, na medida em que apresenta contribuições teóricas em relação à feminilidade e à maternidade de modo crítico e reflexivo. Discute-se a redução da mulher à esfera materna, à invisibilidade, à negação de direitos, seu silenciamento e como os marcadores sociais de raça, classe e gênero influenciam o olhar da sociedade sobre a maternidade e a ocupação dos diversos papéis sociais. Debruçar-se para enxergar a pluralidade do ser mulher e das experiências de ser mãe é importante para a construção de um novo olhar sobre as maternidades. É premente o desenvolvimento de estudos científicos que escutem as narrativas femininas, para que sejam evidenciados os discursos sociais enclausuradores que atravessam sua existência, possibilitando o desenvolvimento de políticas públicas que transformem essa realidade.

Resumo O projeto da transposição do rio São Francisco é parte do conjunto de políticas de acesso à água no semiárido brasileiro e tem incidido sobre os processos de desterritorialização e vulnerabilização na região. O objetivo deste estudo foi analisar os processos de vulnerabilização em comunidades camponesas, decorrentes das obras da transposição do rio São Francisco. Trata-se de um estudo qualitativo, com aplicação de entrevistas semiestruturadas e realização de oficina com camponeses atingidos pela transposição no município de Sertânia (PE). O enfoque teórico-metodológico foi a matriz da reprodução social. Foram identificados diversos processos de vulnerabilização material e simbólica, além de agravos à saúde, como a destruição de reservatórios de água, poços artesianos, cacimbas e terras férteis, a desterritorialização, a incidência de doenças respiratórias agudas, decorrente das escavações para construção dos canais, e processos relativos à saúde mental, relacionando-se à reprodução social e ao modo de vida. A leitura sistêmica ancorada na autoconsciência e na conduta dos processos de vulnerabilização identificou uma ruptura do modo de vida tradicional e efeitos à saúde física e mental dos habitantes da região. Os efeitos negativos desse processo retroagem sobre as vulnerabilidades históricas nos territórios afetados, produzindo novas fragilidades nessas comunidades.

Background: The pancreatic duct system plays a pivotal role in human physiology, facilitating the transport of digestive enzymes and secretions essential for gastrointestinal function. While anatomists have extensively investigated the pancreas's ductal network, the intricacies of pancreatic duct tributaries, including variations in length, angle of entry, and alternating patterns, have continued to captivate scientific inquiry. Aim: To find out the variations in length, angle of entry, and alternating patterns of pancreatic duct tributaries, and discuss the potential clinical implications of our discoveries. Materials and Methods: This study, conducted on 50 human cadavers (comprising 35 perinates and 15 adults), aimed to comprehensively explore the complexities of pancreatic duct tributaries through meticulous dissection. Results: Our research unveiled the following key findings: Variations in Length and Angle of Entry: We observed a remarkable diversity in the number and length of tributaries that join the main pancreatic duct. Additionally, the entry angle exhibited substantial variation, with right-angled tributaries prevalent in 70% of specimens and acute angles in 30%. Understanding these anatomical nuances is crucial for surgical procedures to mitigate inadvertent ductal injury. Alternating and Herringbone Patterns: In 98% of specimens, tributaries alternated between superior and inferior positions along the main pancreatic duct. This alternating pattern may influence the flow of pancreatic secretions and the pathogenesis of pancreatic diseases. In contrast, the rare Herringbone pattern was observed in only 2% of cases, highlighting the unique nature of this anatomical variant. Conclusion: This study contributes valuable insights into the intricate world of pancreatic duct tributaries. By elucidating their anatomy and characteristics, we enhance the safety and efficacy of clinical interventions and expand our understanding of pancreatic physiology and pathology. Further research may delve into the functional implications of these anatomical variations, paving the way for advancements in pancreatic healthcare. KEYWORDS: Pancreatic Duct Tributaries, Anatomical Variations, Pancreatic Surgery, Pancreatic Physiology, Dissection, Herring Bone Pattern, Gastrointestinal Function.

Screw piercing of a workpiece is a process with complex cyclical nature of metal flow in deformation center. Setting up the deformation tool and its calibration, as well as the accuracy of the workpiece feed and release of the hollow billet from deformation zone, have a significant impact on the quality of the hollow billet: dimensional accuracy and presence of defects on its inner and outer surface. In the paper, a technical solution was proposed to increase the stability of piercing a continuously cast workpiece on screw rolling mills. Implementation of the idea involves the use of an improved calibration of the piercing mill tool. For both in order to achieve the workpiece alignment and its stable feeding along rolling axis of the piercing mill, it was proposed to add a special thickening (hump) on the roll input cone and to change calibration of its input section on the ruler in order to meet the workpiece with the rolls earlier: before the initial capture of the workpiece by the rolls, that is, before deformation of metal of the continuously cast workpiece by the rolls. To check and correct the proposed solution, the tasks of FEM-modeling of screw piercing process with a modified design of the tapered roll and ruler were set and solved using the QForm 3D software package. Results of the finite element modeling (FEM) showed that the use of improved tool calibration makes it possible to improve the alignment of the workpiece and ensure its stable position along the rolling axis of the piercing mill, thereby reducing the runout of the workpiece in the deformation center and thereby reducing the force on the rolls from 8 to 5 MN. The results of measurements of the hollow billets’ geometric parameters obtained by FEM showed insignificant relative deviations that fit within the regulatory limits.

A historical overview of the development of iron foundry production in the world is presented. The modern level of the material structure in iron casting has an outstripping growth of ductile cast iron grades. The paper describes the features of iron foundry production in Belarus. Technologies and equipment are significantly inferior to foreign ones in terms of productivity and specific resource costs per unit of product. The specific character of Belarus lies in the still widespread use of cupolas, molds from sand-clay mixtures, predominant use of gray cast iron, and small volumes of ductile cast iron production. The total capacity of all foundries is 557.5 thousand tons of casting per year, but the peculiarity is that only about 250 thousand tons per year are actually produced. Development and implementation of the “Program for the Development of Foundry Industries of the Republic of Belarus for years 2017–2030” made it possible to ensure more efficient operation of the foundry industry in the country. In the near future Belorussian foundry industry will reproduce the global trend for critical casting products: transfer to ductile cast iron instead of gray one and further transition to ausferritic (bainitic) cast iron instead of rolled steel.

Introduction The thyroid cancer in Pakistan is accountable for 1.2% cases of all cancers. Earlier information from Pakistan showed papillary thyroid carcinoma (PTC) to comprise 57-89% of all thyroid malignancies As per World Health Organization (WHO), papillary microcarcinoma of thyroid (PMCT) is a small area of malignant transformation measuring up to 1 cm or less being defined by WHO, that is currently being diagnosed more often than the past. Albeit small, they have the capability of metastasizing to regional lymph node and may disappear after metastasis. Objective To evaluate the prevalence of PMCT in benign multinodular goiter in thyroidectomy specimens. Materials The study was performed in Histopathology Laboratory of Peshawar Medical College, where 32 specimens of multinodular goitre (MNG) patients were received from its affiliated hospitals. The patients’ details were obtained from the hospital records. The specimens were closely examined for the presence of suspicious foci both grossly and microscopically. Results obtained were recorded and data was analyzed statistically. Results All the 32 specimens of the patients were thyroids. The results show a predominance of female patients in surgically resected MNGs with a relatively low incidence of neoplastic transformation. Our study reported two cases of PMCT and both were from different age groups, one was below 25-years and the other was 48-years. Patients mean age was 38.63-years with a SD±12.95- years. The size and weight of the samples varied. The mean of weight was 206.31±304.50 grams, which is due to the reason that many outliers were noted in weight category. Conclusion In thyroid excisions the weight of the excised specimen holds much great importance in determination/diagnosis of the disease. The risk of malignancy is higher in MNG compare to solitary nodules. The prevalence of PMCT (6.25%) are higher in smaller nodules is compare to PTC (3.12%). Furthermore, the fact that our both PMCTs occurred in total thyroidectomy specimens cautions us for their prudent assessment both in gross and histopathological levels.
MESLEKİ REHBERLİKTE ÇOCUK DERGİLERİNİN ROLÜ (YEŞİLAY MAVİ KIRLANGIÇ ÖRNEĞİ)
Authors: YILMAZ Emre
Published: March 2024

Çocukluk yıllarında, “büyüyünce ne olacaksın”, “büyüyünce ne olmak istiyorsun” sorularına muhatap olmayanımız yoktur. Bu soruya her birimiz ailesinden öğrendikleri, çevresinden duydukları, izledikleri ile farklı farklı yanıtlar vermişizdir. Fakat çocukluk yıllarında sorulan bu soruya verdiği yanıt ile hayatının ilerleyen süreçlerinde icra ettiği mesleği birbiriyle örtüşen insan sayısı oldukça azdır. Meslek, bireyin hayat tarzını ve bütün hayatının akışını temelden etkileyen bir özelliğe haizdir. Meslek seçimi insanların hayatlarında başarılı bir birey olup-olamamasını, yaşayacağı muhitin özelliklerini, eş seçimini, gelirini, sosyal statüsünü, ekonomik refah düzeyini; işini severek yapıp-yapmamasını, bütün bunlara bağlı olarak mesleki yeterlik, iş başarısı, iş doyumu, depresyon, tükenmişlik düzeylerini dolayısıyla hayattan genel olarak doyum sağlayıp mutlu olup-olamamasını belirlemede büyük önem arz etmektedir. Bu çalışma Yeşilay tarafından ilkokul çağındaki çocuklara yönelik olarak yayımlanmakta olan Mavi Kırlangıç Çocuk Dergisinin mesleki rehberlik hizmetlerine katkısını incelemek amacıyla gerçekleştirilmiştir. Çalışmada veri toplama aracı olarak nitel araştırma yöntemlerinden dokümantasyon (belge tarama) ve betimsel analiz yöntemi kullanılmıştır. Araştırma sonucunda derginin, ilkokul çağındaki çocukların hemen hemen her meslek hakkında yeterli düzeyde bilgi sahibi olma ve yetenek ve ilgilerine göre en uygun mesleği seçmelerine yardımcı olacak bir içerikte olduğu, derginin meslek tanıtımında çağın yeniliklerini takip ettiği, bireysel farklılıklar ve gelişim döneminin özellikleri dikkate alınarak mesleklerle ilgili güncel bilgilerin uygun bir dil ve uygun bir içerikle çocuklara iletilmeye çalışıldığı tespit edilmiş olup Yeşilay Mavi Kırlangıç Çocuk dergisinin mesleki rehberlik bağlamında ihtiyaca cevap vererek istifade edilebilecek ek bir kaynak olabileceği kanaatine varılmıştır.

An Intersectional Analysis of Precarity and Exploitation: Women and LGBTQIA+ Workers in Substate Neoliberal Systems
Authors: Tomaselli Alexandra
Published: March 2024

The intersection of gender and ethnicity or race lies at the root of structural discrimination and racist practices for accessing the labor market and in the workplace. This discrimination is particularly evident for women and LGBTQIA+ individuals who either belong to ethnic minorities or are migrants. However, numerous other social drivers (e.g., age, class, origins) and external factors (e.g., prejudices, gender‐based violence) further hinder their participation in the work domain and their attainment of fair labor conditions. This article explores how gender, ethnicity, and race intersect and operate with other conditions and factors to perpetuate the precarity and exploitation of women and LGBTQIA+ individuals who find themselves at the nexus of varied intersectional axes. The discussion centers around two neoliberal substate units in the Global North (South Tyrol, in Italy, and Catalonia, Spain) that register low unemployment rates and high rates of migration and that are home to historical, linguistic, and ethnic minorities. This empirical article provides for an informed debate on the lived experience of precarity and exploitation of women and LGBTQIA+ workers, and an analysis of how neoliberal substate units’ labor and gender policies could be reformed.
VIOLÊNCIA DE GÊNERO NÃO ESCOLHE CARGO: AS JORNALISTAS CHEFES E O ASSÉDIO NO TRABALHO
Authors: Amorim Janaina Lopes de , Bueno Thaisa
Published: March 2024

Este artigo trata do assédio sexual e moral contra as jornalistas que ocupam cargos de chefia nas redações de Imperatriz, a segunda maior cidade do Maranhão, região Amazônica do Brasil. O objetivo é verificar como esse crime atinge mulheres em cargos de comando e os impactos disso na rotina jornalística. Para isso, foi escolhida uma abordagem qualitativa, ancorada em entrevistas em profundidade (DUARTE, 2006) com as profissionais da grande imprensa regional. Já a interpretação de dados foi fundamentada na Análise de Conteúdo (BARDIN, 2011). O estudo recorreu a autoras como Roseli Figaro (2018), Heleieth Saffioti (2011), Guacira Louro (1997), Judith Butler (2003) e Helena Hirata (1995) para entender a relação entre gênero, violência e como se constroem as divisões sexuais dos papéis sociais no mundo do trabalho. Já a interseção de raça buscou dialogar com autoras como Lelia Gonzalez (1984) e Maria Lugones (2014). Por fim, esta pesquisa mostra que, mesmo galgando espaços de destaque, as mulheres são assediadas, indicando a importância de se investigar as violências de gênero no jornalismo. Desvela também que as questões de raça impactam de modo diferentes as mulheres negras chefes, ratificando a objetificação dos corpos negros.
