A voz como arquivo afetivo. Testemunhos, silêncio e fotografia em 48 de Susana de Sousa Dias
Authors: Stock Robert
Published: September 2024

O artigo aborda a possibilidade ou impossibilidade de retratar experiências de violência no contexto do cinema documental. A análise centra-se na perspetiva das vítimas da PIDE/DGS (Direção Geral de Segurança) no filme 48 de Susana de Sousa Dias (2009). Através de uma análise detalhada da interação entre o material fotográfico dos arquivos da polícia secreta e as memórias de antigos presos políticos, mostro que este filme representa um importante momento na reavaliação crítica do Estado Novo. Pela primeira vez, um filme confronta diretamente o público com a perspetiva das vítimas, dando-lhes um rosto e uma voz - mulheres e homens não só de Portugal, mas também da antiga colónia de Moçambique.

Authors: Calbino Daniel , Nery Daniela Alvares , Sabino Geruza de Fátima Tomé , Souza Mariana Mayumi Pereira de
Published: September 2024

Entre 2018 e 2022 a democracia universitária foi marcada por retrocessos em vista de sucessivas intervenções nos sistemas eleitorais. Com a recente eleição de Lula, dentre as proposições está a redemocratização societal. Nesse contexto, o trabalho visa problematizar os desafios para o avanço da autonomia e da gestão democrática das Universidades Federais. Para tal, se recorreu a pesquisas documentais e entrevistas com conselhereiros universitários de 10 instituições federais. Os resultados indicam que, dentre os principais desafios destacam-se a necessidade de lidar com projetos de lei que sugerem retrocessos à gestão democrática, bem como a herança da cultura das cátedras marcada pelas resistências internas às formas participativas de gestão.
A ausência da discussão antropológica no contexto Neoliberal: reflexões acerca da educação frente a latência da barbárie
Authors: Lorenzon Mateus , Cenci Angelo Vitório
Published: September 2024

Na contemporaneidade, renunciou-se às grandes discussões antropológicas acerca do homem. Entende-se que o silêncio produzido em torno destes debates produz um estado de deriva antropológica, no qual assume-se acriticamente as concepções subjacentes à racionalidade neoliberal. Contudo, ao analisar o neosujeito necessário e produzido por essa razão-mundo, identifica-se que ele é predisposto a um estado de barbárie, uma vez que a lógica concorrencial e a atomização do indivíduo tendem a produzir ressentimento e o sofrimento psíquico. A fim de restaurar a homeostasia, os indivíduos contemporâneos podem juntar-se a hordas gregárias unidas libidinalmente a um líder. Diante disso, neste ensaio discorre-se acerca das funções da educação em um contexto contemporâneo no qual, em decorrência de uma ausência de discussão antropológica, flerta-se com a latência da barbárie.
A abordagem do Ciclo Político no estudo da política curricular da rede municipal de ensino de Uruguaiana/RS
Authors: Hernandez Cristiane Gonçalves , Marquezan Fernanda Figueira
Published: September 2024

Este artigo discute as políticas curriculares, explorando a proposta do Ciclo de Políticas de Stephen Ball (1992), interpretada por Mainardes (2006). O estudo busca compreender o processo de criação e implementação das políticas curriculares, com foco no Documento Orientador do Território Municipal de Uruguaiana/RS (DOTMU), sob a perspectiva das Coordenadoras da Rede Municipal de Ensino de Uruguaiana. A metodologia utilizada foi a análise documental, centrada no DOTMU como corpus de análise. Apoiado na abordagem do Ciclo de Políticas, o estudo analisa o DOTMU nos três contextos propostos pelos autores: Contexto da Influência, Contexto da Produção do Texto e o Contexto da Prática. Após a análise, especialmente no Contexto da Prática, identificaram-se fragilidades mesmo com a participação dos profissionais da educação na construção do DOTMU. A implementação efetiva de um currículo vivo e consciente, baseado em um planejamento intencional, representa um desafio contínuo. No entanto, o DOTMU revela potencialidades ao ser percebido pelos profissionais como um meio organizador do fazer pedagógico, destacando-se por sua consistência teórica e formulação democrática, contribuindo para o percurso educativo nas escolas da Rede Municipal de Uruguaiana.

Authors: Freitas Margarida Maria Martins de , Sampaio Maynara Karla Soares , Lima Joan Petrus Oliveira , Martins Júnior Francisco Ranulfo Freitas
Published: September 2024

Este trabalho traz a análise dos discursos de treze formadores de Ciências da Natureza sobre o processo de implementação da Base Nacional Comum Curricular na região cearense abrangida pela Coordenadoria Regional de Desenvolvimento da Educação (CREDE 10), comparando-o com os de outros pesquisadores, expondo as articulações e contraposições entre eles. Empregou-se a Análise do Discurso da linha francesa e crítica como o método para categorizar compreensões sobre ensino de Ciências, formação continuada para organização escolar e gestão educacional, coletadas por meio de entrevista semiestruturada. Surgiram contraposições e articulações entre os discursos dos formadores e pesquisadores. As primeiras dizem respeito à não padronização do ensino de Ciências na escola, e as últimas se referem à efetivação de práticas curriculares por meio de diferentes agentes escolares. A reforma educacional na região investigada não é homogênea, mas fornece parâmetros das gestões de suas redes municipais de educação.
Parceria público-privada e sua gênese normativa em Minas Gerais-Brasil e a educação
Authors: Dornellas Liege Coutinho Goulart , Wassem Joyce , Ferreira Eliza Bartolozzi
Published: September 2024

O objetivo deste artigo é narrar o processo legislativo acontecido no Estado de Minas Gerais, o qual aprovou, pela primeira vez no país, uma lei que regulamenta a parceria público-privada (PPP), a Lei Estadual nº 14.868/2003. Num cenário de globalização e da Nova Gestão Pública, apresentamos uma análise documental, a qual é um recorte de tese de Doutorado. Para tanto, utilizamos. como aporte teórico-metodológico, a teoria de Pierre Muller e Surel sobre abordagem cognitiva das políticas, dando ênfase na fase de “inscrição da agenda”. Nossa pesquisa demonstrou que a PPP ultrapassa a definição de privatização. Mais que isso, refere-se à incorporação de ideias do mundo do privado para o seio do aparelho de estado. Nosso estudo, a partir das narrativas apresentadas na arena política, indicou a criação de outras possibilidades de privatização da/na educação, indicando, assim, uma seara fértil para novas pesquisas no campo educacional.
Avaliações externas como tática da governamentalidade: o caso da Prova Brasil
Authors: Santos Karla de Oliveira
Published: September 2024

O objetivo desse estudo é compreender os impactos produzidos pela Prova Brasil em uma escola pública do município de São Miguel dos Campos, no estado de Alagoas, com o maior IDEB municipal, observando as táticas da governamentalidade que são mobilizadas para a cooptação dos sujeitos em busca por bom desempenho e resultados satisfatórios. A metodologia adotada segue a abordagem qualitativa, com foco no estudo de caso e pesquisa bibliográfica, utilizando as técnicas de observação e entrevista semiestruturada com um membro da gestão escolar e uma professora de reforço dos 5º anos A e B, turmas participantes da avaliação oficial. Contudo, concluímos que a Prova Brasil é uma tática da governamentalidade neoliberal que produz saberes e discursos que assujeitaram a comunidade educativa para o alcance de indicadores educacionais e performances exitosas, que tem se apresentado como qualidade da educação, baseada em estatísticas de desempenhos, competitividade e ranqueamentos.
Percepções docentes sobre usos de resultados de avaliações da alfabetização externas à escola
Authors: Rocha Gladys , Schneider Mariza , Martins Raquel
Published: September 2024

Este artigo discute percepções de professoras sobre usos de resultados de avaliações da alfabetização em duas escolas públicas da rede municipal de Sabará, Minas Gerais. O suporte teórico aqui adotado abarca estudos que tratam da avaliação e da alfabetização, como Luckesi (2018), Bonamino; Souza (2012), Soares (2018) e Rocha; Martins; Miranda (2020). A definição das instituições em que faríamos as entrevistas deu-se a partir da articulação dos dados de proficiências médias em Língua Portuguesa, obtidos através do Programa de Avaliação da Alfabetização do Estado Minas Gerais (Proalfa), e os Índices de Nível Socioeconômico (INSE) disponibilizados pelo Instituto Nacional de Estudos e Pesquisas Educacionais Anísio Teixeira (Inep). Isso nos permitiu identificar duas escolas com altas proficiências e níveis socioeconômicos distintos, dentre 27 escolas analisadas. Embora expressem diferentes “modos de ver”, a maioria das professoras entende que as avaliações externas podem informar ao ensino. Percepções que são também permeadas por cobranças em relação aos resultados obtidos e certa frustração quando eles não convergem com os esperados. Observou-se, também, certa dificuldade em relação à compreensão dos instrumentos de avaliação, das informações disponibilizadas e sua apropriação.
Concepção de avaliação em Projeto Político Pedagógico de uma escola estadual do Paraná
Authors: Menezes Rosilda de , Biberg-Salum Tânia Gisela , Figueiredo Helenara Regina Sampaio
Published: September 2024

Este estudo apresenta uma pesquisa documental, com abordagem qualitativa na análise do Projeto Político Pedagógico (PPP) de uma escola pública estadual do Paraná, visando identificar traços de contextualização das práticas e instrumentos avaliativos, conforme a realidade da instituição, bem como de interdisciplinaridade entre os componentes curriculares, no contexto dos anos finais do Ensino Fundamental (EF), conforme as orientações dos documentos norteadores da Educação Básica (EB). Destacou-se a presença, em alguns componentes curriculares, de discursos padronizados e incongruentes, não apresentando alinhamento entre as práticas descritas que indicam que métodos qualitativos devem prevalecer sobre os quantitativos, contudo se destaca a presença de instrumentos tradicionais de avaliação. Compreende-se este como reflexo do atual panorama educacional, no qual o professor se encontra entre dois discursos, o explicito nos documentos norteadores, e o outro, implícito nas avaliações externas que restringem a autonomia dos professores.
How quantitatively important are shocks to consumption and income tax rates for business cycle fluctuations? Lessons from Bulgaria (1999-2020)
Authors: VASILEV Aleksandar
Published: September 2024

This paper analyzes the macroeconomic effects of fluctuations in the marginal tax rates of consumption and income. To this end, stochastic tax rates are introduced as in Braun (1992), into a real-business-cycle setup augmented with a detailed government sector. The model is calibrated to Bulgarian data for the period following the introduction of the currency board arrangement (1999-2020). The quantitative importance of the presence of stochastic taxation is investigated for the stabilization of cyclical fluctuations in Bulgaria. The quantitative effect of such shocks to the marginal tax rates is found to be very small, and thus not important for either business cycle stabilization, or public finance issues.
Explanations of the Polite Hortative form -(i)mash-ō in Current Resources and a Proposition of a Morphological Approach
Authors: Rozwadowski Przemysław Damian
Published: September 2024

The aim of this paper is to demonstrate how the description of Japanese grammar is explained in current resources and to present another, more systemic, morphological approach. It will be achieved by examining explanations of the basic level grammatical unit -(i)mash-ō which can be roughly translated as ‘let’s’. At the beginning the crucial characteristics of present description are portrayed. After showing the basics of the traditional, syllabary description, examples of -(i)mash-ō explanations derived from textbooks are given. Then the author analyzes -(i)mash-ō in accordance with its morphological properties. This approach argues that it is in fact a compound built of smaller units each bearing a separate meaning. Afterwards they can be divided and located in different grammatical dimensions. The morphological segmentation of grammatical units can be used in many other occurrences. This would make paradigmatical descriptions of inflection related phenomena more possible.
Automated Detection of Palatal Deformations Using Deep Learning on Endoscopic Images
Authors: Schild Leona , Zang Jana , Flügel Till , Weiss Deike , Schlaefer Alexander , Latus Sarah
Published: September 2024

A deformation of the hard palate can occur in spinal muscular atrophy and leads to problems with feeding and swallowing in early childhood. An objective analysis of the palatal changes is therefore desirable for early treatment initiation. In this study, we investigate a deep learning approach to automatically detect deformation in endoscopic images which were collected in a prospective in-vivo study on 33 infants. Ratings of five different experts were used to quantify the deformation and to train our network. We investigate different network architectures and data set splits and achieve classification performances of up to 0.85 ± 0.05 when distinguishing between normal and deformation using the Efficient- Net architecture. This combination of endoscopic imaging and deep learning offers a first approach for the objective assessment of palatal changes.
Semi-automatic detection and evaluation of metastases in lymph nodes in diagnostics of the prostate from PET-CT data
Authors: Schmidt V. , Spitz L. , Kreißl M. , Saalfeld S. , Genseke P.
Published: September 2024

We present a novel tool designed for the semiautomatic detection and assessment of prostate cancer during recurrence diagnostics using PET-CT with prostate-specific membrane antigen (PSMA). The tool automatically generates a structured report, which is enhanced by 3D images and ensures the reproducibility of the findings. Moreover, the area of the findings is automatically determined and can be corrected manually. Image data from 50 patients following radical prostatectomy was used. Our approach and its user interface were qualitatively evaluated by a nuclear medicine specialist. The segmentation analysis revealed a requirement for further automation. The resulting report was deemed highly beneficial, particularly in terms of the resulting reproducibility and the presentation of 3D images depicting the findings. The presented tool has great potential for much-needed support in everyday clinical practice, as it facilitates the communication of the diagnostic results to colleagues and patients and thus prevents misunderstandings.
Investigation and experimental evaluation of a mono-pixel X-ray system in healthcare
Authors: Steinert Jule , Salamon Michael , Wittenberg Thomas
Published: September 2024

The acquisition of two-dimensional X-ray images (of non-human objects) is quite expensive, primarily due to the costly flat-panel or line detectors. Reducing these costs could open up new possibilities in healthcare applications, such as inspecting limb prostheses for cracks and defects or safety-related material testing of helmets and child seats. In this contribution, two different setups of low-cost mono-pixel X-ray scanners are described: a small scanner with a working volume of 20 x 20 x 20 cm3 and a large system with a volume of 150 x 230 x 110 cm3. Using these novel mono-pixel X-ray scanning systems, various objects - ranging from an X-ray phantom and a human skull phantom to a high-end limb prosthesis with integrated electronics - were scanned and investigated. Compared to conventional X-ray systems, the mono-pixel systems can depict these objects without the distortion problems of cone beam detectors. Although the scanning procedure is time-consuming, the results are quite promising. Mono-pixel X-ray-scanning is a novel modality capable of scanning largescale objects with low-dose radiation. While it is currently not suitable for human applications due to the long scanning times, it can still be used for the non-destructive testing of large-scale medical devices, such as e.g. arm and leg prosthesis.

Published: September 2024

Lower back pain (LBP) is a common symptom that can be linked to the degeneration of intervertebral discs or injuries to vertebrae. Accurate segmentation of lumbar spinal structures is vital for image-based surgery planning but can be resource intensive. Recent studies have shown that U-Net models can be used reliably to segment vertebrae and intervertebral discs from medical imaging data. This study investigated the potential of combining multiple planar MRI images to segment these structures automatically. The study used MRI data from 83 patients with back pain of the lower spine, with ground truth segmentations performed by a spine surgery specialist using Mimics software. The segmentation models were trained using a specialized patient batching method and a FiLMed U-Net model, which applies a Feature-wise Linear Modulation layer to improve mask generation. The models were trained using a 10-fold cross validation study, and the dice loss was used as the objective function. The study found that both patient batching and FiLM layers improve results by around 5% compared to a baseline U-Net. The average IoU scores of the patient batching method were 0.896 for vertebrae and 0.876 intervertebral disc segmentation. The FiLMed U-Net model achieved average IoU scores of 0.844 and 0.814 and against a baseline of 0.837 and 0.774, respectively. A web-based tool was developed to enable medical personnel to assess segmentation quality visually. Overall, the study indicates that U-Nets show better segmentation potential when using imaging data with complete 3D information of one patient. Future studies should focus on increasing the dataset size and exploring other 3D model architectures to improve segmentation performance.
The Expression of Gratitude in English and Arabic Doctoral Dissertation Acknowledgements
Authors: Ghai Affef , Alghazo Sharif
Published: September 2024

This corpus-based study explores the expression of gratitude in the acknowledgement section of doctoral dissertations in both English and Arabic. The objective is to analyse how gratitude in academic discourse is structured in these languages and to explore any differences related to gender. The study examines 80 dissertations (40 in English and 40 in Arabic), further divided by the authors’ gender (20 male and 20 female for each language). Data collection involved searching for doctoral dissertations from various sources, verifying the authenticity of the native language through biographical checks, and categorising the acknowledgements based on the year and field of study. The analysis utilised a mixed-methods approach based on Hyland and Tse’s (2004) framework, enabling quantitative and qualitative text analysis. The study revealed distinct differences in gratitude expression patterns between English and Arabic dissertations: English acknowledgements often used performative verbs and adjectives, while Arabic acknowledgements primarily employed nominalisation. Notably, Arabic texts showed no use of passive constructions or adjectives. Gender-related differences were also observed, such as the preference for nominalisation among male Arabic authors and the preference for bare mention among female English authors. These findings underscore the significant cultural and linguistic influences on the construction of gratitude in academic acknowledgements. The research contributes valuable insights into pedagogical approaches to teaching academic writing and highlights the interplay between language, culture, and gender in scholarly communications.
Quantifier float in Hmong
Authors: White Nathan M.
Published: September 2024

The typology of quantifier float (QF) in classifier languages has been the subject of research in several recent works. Some proposals suggest that languages should either have noun classifiers or the ability for the quantifier to “float”, that is, appear separate from the noun it quantifies. QF has never been described for any Hmong-Mien language, leaving a critical gap in existing work and limiting the existing typology. The current work fills this gap with an analysis of quantifier float in Hmong, and considers that Hmong possesses both bare classifiers and quantifier float, a combination previously unattested in the literature on QF and contrasts with current typological proposals. Hmong allows this via two quantifier + noun orderings (QN and NQ) related to two functions of the classifier system that both permit quantifier float. The QN-only ordering is canonically associated with indefinite nouns, and the NQ ordering involves a nested noun phrase structure and is associated with definite nouns (generally with inner NP-internal bare noun classifiers) and partitive or distributive readings. The QN-only ordering is particularly significant for the typology as quantifier float to the right is permitted for quantifier + classifier sequences associated with a prenominal NP-internal position, where the classifier involved in this QF pattern occupies the same syntactic position within the noun phrase as the bare noun classifier in noun phrases generally.
An Application of the Dagum Type III Model to Measure Household Net Wealth Inequality in Indonesia
Authors: Soseco Thomas , Olivia Susan , Oxley Les
Published: September 2024

This paper applies the Dagum Type III model to measure household net wealth inequality in Indonesia utilising data from the Indonesian Family Life Survey (IFLS) 1993–2014. The results are the distribution of household net wealth in Indonesia is right-skewed, with long-and sparse-hand tails that reflect a large proportion of households that have very low net wealth and a small proportion of households that have very high net wealth. Further, the inequality of household net wealth in Indonesia declined, as shown by the decrease in the Gini coefficient.
Subgroups of even Artin groups of FC type
Authors: Antolín Yago , Foniqi Islam
Published: September 2024

We prove a Tits alternative theorem for subgroups of finitely presented even Artin groups of FC type, stating that there exists a finite index subgroup such that every subgroup of it is either finitely generated abelian, or maps onto a non-abelian free group.
Parabolic subgroups play a pivotal role in our proofs, and we show that parabolic subgroups of even Artin groups of FC type are closed under taking roots.
Cultural Bias in Large Language Models: A Comprehensive Analysis and Mitigation Strategies
Authors: Liu Zhaoming
Published: September 2024

This paper delves into the intricate relationship between Large Language Models (LLMs) and cultural bias. It underscores the significant impact LLMs can have on shaping a more equitable and culturally sensitive digital landscape, while also addressing the challenges that arise when integrating these powerful AI tools. The paper emphasizes the immense significance of LLMs in contemporary AI research and applications, underpinning many systems and algorithms. However, their potential role in perpetuating or mitigating cultural bias remains a pressing issue warranting extensive analysis. Cultural bias stems from various intertwined factors; the following analysis categorizes cultural bias shaping LLMs into three dimensions: data quality, algorithm design, and user interaction dynamics. Furthermore, the impacts of LLMs on cultural identity and linguistic diversity are scrutinized, highlighting the interplay between technology and culture. The paper advocates responsible AI development, outlining mitigation strategies such as ethical guidelines, diverse training data, user feedback mechanisms, and transparency measures. In conclusion, the paper emphasizes that cultural bias in LLMs is not solely a problem but also presents an opportunity. It can enhance our awareness and critical understanding of our own cultural biases while fostering curiosity and respect for diverse cultural perspectives.

Authors: Найдьонов А. , Коваль В. , Барбаш В. , Душейко М. , Ященко О.
Published: September 2024

Вступ. На сьогодні в датчиках вигину використовують штучні полімери, які забруднюють навколишнє середовище. Наноцелюлоза (НЦ) є біорозкладним і гнучким матеріалом, однак має низьку здатність до видовження, що обмежує її застосування для оцінки рухів людини. Одним із способів вирішення цієї проблеми є створення композитів на основі НЦ.Проблематика. Актуальним питанням є синтез сенсорів вигину на основі біорозкладного матеріалу (біонанокомпозиту із наноцелюлози та полівінілового спирту (ПВС)) для використання у сенсорах, що можуть бути застосовані для аналізу м’язової активності людини.Мета. Визначення впливу матеріалу підкладки сенсора на робочі параметри сенсорів вигину.Матеріали й методи. Застосовано методи синтезу: кислотний гідроліз органосольвентної целюлози для отримання НЦ, лиття з використанням вакууму для отримання нанокомпозитних плівок НЦ-ПВС і методу високочастотного магнетронного розпилення для виготовлення тензочутливих плівок. Методами дослідження були оптична спектрометрія, тестування на механічне видовження та розрив, тестування на біорозкладність у ґрунті, тензометрія.Результати. Синтезовано композити НЦ-ПВС та на їхній основі створено датчики вигину. Основні електричніпараметри одержаних сенсорів вигину: коефіцієнт тензочутливості досягав 7,52, реверсивність — 9—23 %, повзучість — 0,17—0,5%/хв. При цьому біорозкладність композиту становила 21—70% втрати маси за 4,5 місяців. Досліджено вплив матеріалу підкладки сенсорів на функціональні властивості цих датчиків. Встановлено, що додавання ПВС до НЦ покращило оптичні та механічні властивості композитів.Висновки. Оптимальним складом композиту можна вважати суміш НЦ-ПВС у співвідношенні 1 : 1. Розроблені датчики вигину можуть бути використані для моніторингу активності м’язів людини, що є перспективним для застосування у медицині, спорті, реабілітації.

Tourism industry is important for national economies, and, in this regard, it is vital to monitor its competitiveness. The Travel and Tourism Competitiveness Index (TTCI), developed and reported by the World Economic Forum, serves this purpose by providing a consistent framework, explanatory factors, and corresponding data sets. In this paper we exploit the past data sets of this index, first, to verify that in several countries, competitiveness in tourism and travel industries hardly changes over time. Next, we identify countries that show consistency in travel–tourism competitiveness and separate them into classes of best, worst, intermediate, and ambiguous past performance. Building on such a classification, we apply linear discriminant analysis (LDA) as an alternative to the TTCI computational framework in order to compose the new synthetic index TTCI-LDA, which assesses countries’ competitiveness. The analysis of country scores obtained from this index has revealed that ICT readiness and touristic service infrastructure are important for tourism competitiveness. The score thresholds for the best–worst country cases in each class provide additional useful information for management, benchmarking, and policy decision making.

Published: September 2024

This paper investigates the financial importance of development banks across regions and income groups. We construct a global banking dataset for the period 1995 to 2021 and analyse the distribution of development banking assets across macro regions and country income groups. We create a composite global and national Development Bank Financial Importance index (DBFI index) that enables us to rank the most financially important development banks across the globe. Development banks play significant and diverse roles in the global financial system, but their financial importance varies across regions and income groups. The paper offers a broad analysis of the global development banking landscape and advances the area of research further.

Campylobacteriosis is one of the most prevalent foodborne bacterial diseases. Infected chickens and poultry products are a possible source of this illness in people all over the world. Therefore, the objective of this current meta-analysis was to summarise the available data on the prevalence of thermotolerant Campylobacter species in poultry and their products. A systematic literature search was conducted to gather pertinent articles from 2000 to 2021, using globally recognised four electronic databases, including Google Scholar, PubMed, Science Direct, and Scopus. The mean prevalence of campylobacteriosis in poultry species and their products (meat, eggs, and offal) was 44% (95% CI: 39–50%) with the highest prevalence in Australia (67%). Among the European countries, France had the maximum prevalence rate of 76%, while Japan had recorded 61% as the peak among Asian countries. Prevalence rates of 43% and 56% were calculated in United States and Brazil representing the American region. In the species-wise results, the mean prevalence rates of Campylobacter jejuni and Campylobacter coli were 29% and 16%, correspondingly. In case of live birds, chickens and turkeys possessed maximum prevalence rates of 47% and 40%, whereas 46% and 63% were recorded from poultry meat and liver. Besides, categorising the difference sources of contamination, the maximum prevalence rate of 62% was found in the poultry processing plants followed by 54% from supermarkets and 38% from farms. According to the current meta-analysis, Campylobacter jejuni was the most common bacterium worldwide, and poultry meat – the most frequent source of human infection. The predominance of Campylobacter species is a threat for public health, and national authorities must undertake strategies to control this disease in each country with the goal of establishing adequate risk management measures.

Metallic materials, predominantly steels, are the most common structural materials in the various components along the hydrogen supply chain. Ensuring their sustainable and safe use in hydrogen technologies is a key factor in the ramp-up of the hydrogen economy. This requires extensive materials qualification, however, most of the accepted; and standardized test methods for determining the influence of gaseous hydrogen on metallic materials describe complex and costly procedures that are only available to a very limited extent worldwide. The hollow specimen technique is a simple, rapid, and economical method designed to overcome the limitations of the current methods for the qualification of metallic materials under high-pressure hydrogen gas. However, this technique is not yet standardized. The TransHyDE-H2Hohlzug project is presented in this article, along with the main steps required to optimize the hollow specimen technique. This includes closing knowledge gaps related to the specimen geometry, surface quality, and gas purity in dedicated working packages, thus contributing to a comprehensive standardization of the technique for tests in high-pressure hydrogen gas.

Impact statement

The hydrogen economy is considered a key solution for achieving climate neutrality in Europe, as it plays a crucial role in the decarbonization of sectors such as transport, industry, power, etc. Ensuring the safety and reliability of infrastructure is crucial for the ramp-up of the hydrogen economy. Therefore, it is necessary to meticulously study the materials and components used for infrastructure under conditions that closely resemble in-service conditions. The currently standardized methods are limited as they do not precisely replicate in-service conditions, and when they do, they are often complex, costly, and not easily accessible. This article presents the hollow specimen technique, a simple, and economical method developed to address the limitations of current standardized methods. The results from this work will contribute to the standardization of this technique for tests in high-pressure hydrogen gas. This will enable a faster evaluation of materials for hydrogen applications by industry and academia, thereby contributing to the growth of the hydrogen economy.

Barium titanate (BTO) is a ferroelectric perovskite used in electronics and energy storage systems because of its high dielectric constant. Decreasing the BTO particle size was shown to increase the dielectric constant of the perovskite, which is an intriguing but contested result. We investigated this result by fabricating silicone-matrix nanocomposite specimens containing BTO particles of decreasing diameter. Furthermore, density functional theory modeling was used to understand the interactions at the BTO particle surface. Combining results from experiments and modeling indicated that polymer type, particle surface interactions, and particle surface structure can influence the dielectric properties of polymer-matrix nanocomposites containing BTO.

Published: September 2024

This paper examines the ongoing changes in marketing research brought about by the development of marketing discourse. Given the interdisciplinary character of marketing, which has made such research develop as a multi-paradigmatic science, it is important to show the applications of social studies paradigms to marketing and marketing research, including the neopositive-functional-systematic, the interpretative-symbolic, the radical structuralist and the postmodernist paradigms. How marketing research is developing is also shown in the context of expectations rising as a result of ever greater changes in the market and the use of new technologies in marketing research, which broaden the possibilities for gathering information for business management.
