    I Modellbücher di Bertolt Brecht e del Berliner Ensemble si configurano come elementi dal carattere duplice e controverso, in bilico fra lo statuto di exempla per i futuri allestitori e quello di dispositivi interni al lavoro dell’ensemble, risultanti dinamiche della processualità scenica. L’interesse per la fotografia e il montaggio, che in Brecht assume molteplici forme – dando vita, ad esempio, ad opere come L’Abicí della guerra – si colloca al centro della composizione di tali strumenti, veri e propri esempi di assemblaggio di frammenti scenici. I Modellbücher trovano la propria ragion d’essere entro le dinamiche della regia brechtiana, di cui si prestano a tradurre le pratiche. La tesi indaga lo statuto dei Modellbücher, facendo riferimento alla storia degli studi e all’indagine archivistica condotta presso il Bertolt-Brecht-Archiv di Berlino fra 2018 e 2019.Brecht’s and Berliner Ensemble’s Modelbooks have double and controversial character, between the status of examples for other directors and that of devices for the work of the ensemble, dynamic resulting of the scenic process. The interest in photography and editing, which takes multiple forms in Brecht - giving life, for example, to works such as Kriegsfibel - is at the center of the composition of these instruments, which are examples of the editing of scenic fragments. The Modelbooks find their raison d'etre within the dynamics of the Brechtian direction whose practices they translate. The thesis investigates the status of the Modelbooks, referring to the history of studies and to the archival investigation at the Bertolt-Brecht-Archiv in Berlin between 2018 and 2019

    Human affective behavior analysis focuses on analyzing human expressions or other behaviors to enhance the understanding of human psychology. The CVPR 2023 Competition on Affective Behavior Analysis in-the-wild (ABAW) is dedicated to providing high-quality and large-scale Aff-wild2 for the recognition of commonly used emotion representations, such as Action Units (AU), basic expression categories(EXPR), and Valence-Arousal (VA). The competition is committed to making significant strides in improving the accuracy and practicality of affective analysis research in real-world scenarios. In this paper, we introduce our submission to the CVPR 2023: ABAW5. Our approach involves several key components. First, we utilize the visual information from a Masked Autoencoder(MAE) model that has been pre-trained on a large-scale face image dataset in a self-supervised manner. Next, we finetune the MAE encoder on the image frames from the Aff-wild2 for AU, EXPR and VA tasks, which can be regarded as a static and uni-modal training. Additionally, we leverage the multi-modal and temporal information from the videos and implement a transformer-based framework to fuse the multi-modal features. Our approach achieves impressive results in the ABAW5 competition, with an average F1 score of 55.49\% and 41.21\% in the AU and EXPR tracks, respectively, and an average CCC of 0.6372 in the VA track. Our approach ranks first in the EXPR and AU tracks, and second in the VA track. Extensive quantitative experiments and ablation studies demonstrate the effectiveness of our proposed method

    Comedians without a Cause: The Politics and Aesthetics of Humour in Dutch Cabaret (1966-2020)

    Comedians play an important role in society and public debate. While comedians have been considered important cultural critics for quite some time, comedy has acquired a new social and political significance in recent years, with humour taking centre stage in political and social debates around issues of identity, social justice, and freedom of speech. To understand the shifting meanings and political implications of humour within a Dutch context, this PhD thesis examines the political and aesthetic workings of humour in the highly popular Dutch cabaret genre, focusing on cabaret performances from the 1960s to the present. The central questions of the thesis are: how do comedians use humour to deliver social critique, and how does their humour resonate with political ideologies? These questions are answered by adopting a cultural studies approach to humour, which is used to analyse Dutch cabaret performances, and by studying related materials such as reviews and media interviews with comedians. This thesis shows that, from the 1960s onwards, Dutch comedians have been considered ‘progressive rebels’ – politically engaged, subversive, and carrying a left-wing political agenda – but that this image is in need of correction. While we tend to look for progressive political messages in the work of comedians who present themselves as being anti-establishment rebels – such as Youp van ‘t Hek, Hans Teeuwen, and Theo Maassen – this thesis demonstrates that their transgressive and provocative humour tends to protect social hierarchies and relationships of power. Moreover, it shows that, paradoxically, both the deliberately moderate and nuanced humour of Wim Kan and Claudia de Breij, and the seemingly past-oriented nostalgia of Alex Klaasen, are more radical and progressive than the transgressive humour of van ‘t Hek, Teeuwen and Maassen. Finally, comedians who present absurdist or deconstructionist forms of humour, such as the early student cabarets, Freek de Jonge, and Micha Wertheim, tend to disassociate themselves from an explicit political engagement. By challenging the dominant image of the Dutch comedian as a ‘progressive rebel,’ this thesis contributes to a better understanding of humour in the present cultural moment, in which humour is often either not taken seriously, or one-sidedly celebrated as being merely pleasurable, innocent, or progressively liberating. In so doing, this thesis concludes, the ‘dark’ and more conservative sides of humour tend to get obscured

    The low density, hot Jupiter TOI-640 b is on a polar orbit

    TOI-640 b is a hot, puffy Jupiter with a mass of 0.57±0.020.57 \pm 0.02 MJ_{\rm J} and radius of 1.72±0.051.72 \pm 0.05 RJ_{\rm J}, orbiting a slightly evolved F-type star with a separation of 6.33−0.06+0.076.33^{+0.07}_{-0.06} R⋆_\star. Through spectroscopic in-transit observations made with the HARPS spectrograph, we measured the Rossiter-McLaughlin effect, analysing both in-transit radial velocities and the distortion of the stellar spectral lines. From these observations, we find the host star to have a projected obliquity of λ=184±3∘\lambda=184\pm3^\circ. From the TESS light curve, we measured the stellar rotation period, allowing us to determine the stellar inclination, i⋆=23−2+3∘i_\star=23^{+3\circ}_{-2}, meaning we are viewing the star pole-on. Combining this with the orbital inclination allowed us to calculate the host star obliquity, ψ=104±2∘\psi=104\pm2^\circ. TOI-640 b joins a group of planets orbiting over stellar poles within the range 80∘−125∘80^\circ-125^\circ. The origin of this orbital configuration is not well understood.Comment: 15 pages, 12 figures, accepted for publication in A&A, in pres

    Sobre o Estilo na História Intelectual

    Style in past Ages denotes general sensibilities that guide thought and action. Attempts to show how style derives from the material circumstances of living remain inconclusive because of the difficulty in deciding which parts of culture past lie at the center of it. The advantages and the drawbacks of modelsand schemes offered by major theorists of the past several generations are used to support the proposition that philosophy is a dubious guide for practicing intellectual historians, who do best when they make their own methods from the materialthey study.O estilo no passado denotava sensibilidades gerais que guiam o pensamento e a ação. Tentativas de mostrar como o estilo deriva das circunstâncias materiais da vida permanecem inconclusivas por causa da dificuldade em decidir quais partes da cultura do passado estão no centro dele. As vantagens e desvantagens dos modelos e esquemas oferecidos pelos principais teóricos das gerações passadas são usadas para apoiar a proposição de que a filosofia é um guia duvidoso para praticantes da história intelectual, que se saem melhor quando criam seus próprios métodos a partir do material que estudam

    Hyper-entanglement between pulse modes and frequency bins

    Full text link
    Hyper-entanglement between two or more photonic degrees of freedom (DOF) can enhance and enable new quantum protocols by allowing each DOF to perform the task it is optimally suited for. Here we demonstrate the generation of photon pairs hyper-entangled between pulse modes and frequency bins. The pulse modes are generated via parametric downconversion in a domain-engineered crystal and subsequently entangled to two frequency bins via a spectral mapping technique. The resulting hyper-entangled state is characterized and verified via measurement of its joint spectral intensity and non-classical two-photon interference patterns from which we infer its spectral phase. The protocol combines the robustness to loss, intrinsic high dimensionality and compatibility with standard fiber-optic networks of the energy-time DOF with the ability of hyper-entanglement to increase the capacity and efficiency of the quantum channel, already exploited in recent experimental applications in both quantum information and quantum computation

    Dissertação de Mestrado Integrado em Medicina VeterináriaA crescente exigência e procura de produtos de elevada qualidade por parte dos consumidores implica uma constante atualização do conhecimento dos alimentos e das boas práticas de higiene por parte das empresas intervenientes na indústria alimentar. A certificação é uma forma de garantir, não só a qualidade dos produtos, sejam eles alimentares ou não alimentares, mas também um controlo constante e atualização dos processos envolvidos na comercialização. A IFS Logistics é uma norma de logística que pretende assegurar a máxima transparência e confiança em empresas de distribuição e/ou armazenamento de produtos alimentares e não alimentares. Com o intuito de implementar esta norma na secção “Entrega Direta ao Cliente” de uma loja de comércio grossista, foi desenhada uma nova auditoria específica para a secção em estudo, para poder analisá-la e prepará-la para os requisitos vigentes na IFS Logistics 2.2. Este estudo teve como objetivo avaliar o impacte da introdução das auditorias “Entrega Direta ao Cliente”, na classificação das auditorias de “Segurança dos Alimentos” que também verificam a secção. Em ambas as auditorias foram avaliados requisitos de higiene, temperatura, qualidade e boas práticas. Para tal, foram realizadas novas auditorias de Segurança dos Alimentos, exclusivas da “Entrega Direta ao Cliente”, em cada uma das lojas de venda por groso de géneros alimentícios, considerando o período compreendido entre março de 2020 e março de 2021. As auditorias “Segurança dos Alimentos” a toda a loja continuaram a realizar-se, tendo sido também alvo de estudo os resultados nelas obtidos entre janeiro de 2020 e janeiro de 2021. Não foram encontradas diferenças significativas entre as classificações obtidas pela secção em estudo nas auditorias de “Segurança dos Alimentos” antes e após a introdução das auditorias “Entrega Direta ao Cliente”. Comparando a classificação na primeira (janeiro de 2020) e na última (janeiro de 2021) auditorias, a variação global da pontuação é, inclusive, negativa (-2). No entanto, nos dois tipos de auditoria, registaram-se Não Conformidades idênticas e recorrentes de limpeza e manutenção, bem como falhas nas temperaturas de produtos e veículos de transporte. Estes resultados revelam a necessidade de uma maior sensibilização dos colaboradores relativamente aos procedimentos e práticas de higiene e sistemas de gestão de Segurança dos Alimentos.ABSTRACT - Monitoring the Internal Audit Plan in the Scope of Food Safety in a Wholesale Company - The growing demand and request for high quality products by consumers implies a constant updating of knowledge about food and good hygiene practices by companies in the food industry. Certification is a way to guarantee not only the quality of products, whether food or nonfood, but also constant control and updating of the processes involved in commercialization. IFS Logistics is a standard that aims to ensure maximum transparency and trust in distribution and/or storage companies for food and non-food products. In order to implement this standard in the “Delivery” section of a wholesale store, a new specific audit was designed for the section under study, in order to analyze and prepare it for the requirements in force at IFS Logistics 2.2. This study aimed to assess the impact of the introduction of the “Delivery” audits, on the classification of the “Food Safety” audits that also verify the section. In both audits, hygiene, temperature, quality and good practices requirements were evaluated. To this end, new Food Safety audits were carried out, exclusive to "Delivery", in each of the wholesale food stores, considering the period between March 2020 and March 2021. The audits "Food Safety” to the entire store continued to take place, with the results obtained between January 2020 and January 2021 being also targeted. No significant differences were found between the ratings obtained by the section under study in the “Food Safety” audits before and after the introduction of the “Direct Delivery to the Customer” audits. Comparing the rating in the first (January 2020) and in the last (January 2021) audits, the overall score variation was even negative (-2). However, in both types of audit, there were identical and recurring Non-Conformities in cleaning and maintenance, as well as failures in the temperatures of the products and transport vehicles. These results reveal the need for greater employee awareness regarding hygiene procedures and practices and Food Safety managements systems.N/

    Interdisciplinary Pain Rehabilitation Programs: Evidence and Clinical Real-World Results

    Get PDF
    Chronic pain conditions are influenced by and interact with physical, psychological, social, and contextual factors. These conditions are associated with psychological distress, poor health, sick leave, and high socio-economic costs. Therefore, modern clinical practice applies a biopsychosocial (BPS) framework. Interdisciplinary pain rehabilitation programs (IPRPs) for chronic pain distinguish themselves as well-coordinated complex interventions. This chapter describes the contents of such programs. We will briefly review the evidence for IPRPs and discuss problems when evaluating these complex interventions. Furthermore, we will report practice-based results from a large Swedish pain registry—the Swedish Quality Registry for Pain Rehabilitation (SQRP). The SQRP collects data from a relevant special clinical department in Sweden—i.e., real-life outcomes will be depicted. Characteristics of patients that benefit the most from IPRPs will be described and discussed. The indications for IPRPs will also be presented. Finally, we will discuss how to improve rehabilitation for chronic pain patients

    RESUMEN En Dismantling the Borders comparo las actividades laborales de mujeres en Brabante y Bizkaia de 1420 a 1550. Historiadores especializados en género han estado debatiendo las diferencias en las oportunidades laborales de mujeres premodernas en el norte y en el sur de Europa. Algunos investigadores argumentan que las diferencias en las estructuras legales y familiares conllevaron menos oportunidades económicas para las mujeres en el sur de Europa. En mi estudio, reevalúo este debate y argumento que se han de reevaluar los contextos locales, en concreto, las instituciones responsables de la organización del trabajo en las diferentes regiones. En las ciudades Brabantinas – Malinas y Amberes – la mayor parte de las ocupaciones estaban organizadas en gremio, unas instituciones extremadamente patriarcales y masculinizadas. Por ende, el trabajo de las mujeres dependía en gran medida de su estatus familiar y social. La ausencia de estas instituciones en Bilbao – la ciudad Bizkaína estudiada – favoreció unas oportunidades laborales más independientes para las mujeres activas en sectores del mercado laboral poco lucrativos.ABSTRACT In Dismantling the Borders I compare women’s labour opportunities in Brabant and Biscay from 1420 to 1550. Scholars studying gender in premodern Europe have been debating differences in premodern women’s labour opportunities in northern and southern Europe. Some scholars have argued that diverging family structures and legal structures in the two regions resulted in better economic positions for women in northern Europe. In my research project, I reassess this debate and argue for involving local contexts in the regional comparison – more specifically the institutions responsible for the organization of work. In the Brabantine case studies, Antwerp and Mechelen, most occupations were organized in guilds – extremely patriarchal and masculine institutions. As a result of this organization in guilds, women’s labour opportunities in Brabant were highly dependent on their social status and marital status. In Bilbao – the Biscayan case study – occupations were rarely organized in such corporations, resulting in more independent labour opportunities for women active in less lucrative market sectors in the town
