    Este ensaio pretende investigar a nudez no teatro de Marcio Abreu e da companhia brasileira de teatro como estratégia crítica para desestabilizar comportamentos naturalizados no teatro. As peças Descartes com lentes, Isso te interessa?, PROJETO bRASIL e Nós serão brevemente abordadas como exemplos em que a nudez aparece como artifício de elaboração formal que pode convocar o corpo do espectador à presença e à atenção e sua mente a elaborar sobre as coisas do teatro e sobre as coisas do mundo.This paper intends to investigate nudity in the theatre of Marcio Abreu and companhia brasileira de teatro as a critical strategy to destabilize naturalized behaviors in the theatre. Four plays – Descartes com lentes, Isso te interessa?, PROJETO bRASIL and Nós – will be briefly analyzed as examples of how nudity is used as an artifice of formal elaboration which may summon the spectator’s body to an estate of presence and attention and summon their mind to elaborate on theatre and consequently on the world

    The article concerns the work of Brazilian stage director ChristianeJatahy in five performances (four theatre plays and an opera), aimingto analyze her stagings regarding the ideas of system, device, mediationand repetition. Through an investigation of her dramaturgical operations,I try to identify procedures adopted to destabilize repetitionin the theatre, such as the creation of counter-devices, the work withsystems in the creative process of a scenic dramaturgy that is alsoan actor’s dramaturgy, as well as the relation between theatre andcinema.O artigo aborda o trabalho da encenadora brasileira Christiane Jatahyem cinco espetáculos (quatro peças de teatro e uma ópera), com o propósitode analisar as encenações a partir das ideias de sistema, dispositivo,mediação e repetição. Através da análise de suas operaçõesdramatúrgicas, procuramos identificar procedimentos adotados como objetivo de desestabilizar a repetição no teatro, como a criação decontradispositivos, o trabalho com os sistemas para a criação de umadramaturgia cênica e atorial, além da relação entre teatro e cinema

    Human Alignment of Large Language Models through Online Preference Optimisation

    Full text link
    Ensuring alignment of language models' outputs with human preferences is critical to guarantee a useful, safe, and pleasant user experience. Thus, human alignment has been extensively studied recently and several methods such as Reinforcement Learning from Human Feedback (RLHF), Direct Policy Optimisation (DPO) and Sequence Likelihood Calibration (SLiC) have emerged. In this paper, our contribution is two-fold. First, we show the equivalence between two recent alignment methods, namely Identity Policy Optimisation (IPO) and Nash Mirror Descent (Nash-MD). Second, we introduce a generalisation of IPO, named IPO-MD, that leverages the regularised sampling approach proposed by Nash-MD. This equivalence may seem surprising at first sight, since IPO is an offline method whereas Nash-MD is an online method using a preference model. However, this equivalence can be proven when we consider the online version of IPO, that is when both generations are sampled by the online policy and annotated by a trained preference model. Optimising the IPO loss with such a stream of data becomes then equivalent to finding the Nash equilibrium of the preference model through self-play. Building on this equivalence, we introduce the IPO-MD algorithm that generates data with a mixture policy (between the online and reference policy) similarly as the general Nash-MD algorithm. We compare online-IPO and IPO-MD to different online versions of existing losses on preference data such as DPO and SLiC on a summarisation task

    A utiliza\ue7\ue3o de mudas de qualidade \ue9 fundamental para o estabelecimento de plantios florestais, o que \ue9 alcan\ue7ado por meio de t\ue9cnicas adequadas desde a fase de viveiro. Assim, este trabalho teve por objetivo investigar a influ\ueancia de diferentes composi\ue7\uf5es de substratos e do volume de recipiente (tubetes) no crescimento de mudas de canjerana ( Cabralea canjerana ), no viveiro e no campo. Em viveiro foram avaliadas tr\ueas composi\ue7\uf5es de substratos \ue0 base de turfa (100% turfa, turfa + 20% casca de arroz carbonizada (CAC) e turfa + 40% CAC) combinadas com dois tamanhos de tubetes (100 e 280 cm3). Foram realizadas mensalmente, durante 330 dias, mensura\ue7\uf5es do di\ue2metro do coleto (DC) e da altura (H), e foi calculada tamb\ue9m a rela\ue7\ue3o H/DC. Aos 330 dias foram avaliadas as massas secas radicular, a\ue9rea e total e o \uedndice de qualidade de Dickson. Os mesmos tratamentos foram avaliados em campo, durante um per\uedodo de 360 dias, e foi mensurado a cada 90 dias, o DC e a H, e calculada a H/DC. No viveiro e em campo, os experimentos foram conduzidos com delineamento experimental de blocos ao acaso, com quatro repeti\ue7\uf5es. Mudas de canjerana podem ser produzidas em substrato composto por 60% de turfa e 40% de casca de arroz carbonizada sem preju\uedzo do seu crescimento em campo, tendo em vista a economia que representa no viveiro. O uso do tubete de 280 cm3 proporcionou somente crescimento superior das mudas na fase de plantio, sendo que o di\ue2metro do coleto e a massa seca radicular expressaram o melhor desempenho.The use of quality seedlings is essential for the establishment of forest plantations, which is achieved through the use of appropriate techniques from the nursery. Thus, this study aimed to investigate the influence of substrate composition and volume of container (tubes) in the growth of seedlings of canjerana ( Cabralea canjerana ), in the nursery and field. In nursery, three compositions of peat substrates were evaluated (100% peat, peat + 20% rice hulls (RH) and peat + 40% RH) and combined with two sizes of containers (100 and 280 cm3). Measurements of root collar diameter (DC) and height (H) were performed monthly during 330 days, and the ratio H/DC was also calculated. At 330 days, the root, air and total dry masses and Dickson\u2019s quality index were assessed. The same treatments were evaluated in the field during a period of 360 days and DC and H were measured and H/DC was calculated in every 90-day period. In the nursery and field experiments were carried out with experimental design of random blocks, with four replications. Seedlings of canjerana can be produced in a substrate composed of 60% peat and 40% of rice hulls without harming its growth in the field, with a view that the economy is in nursery. The tube of the tube in the size 280 cm3 only provided superior growth of seedlings during the field phase, where seedlings produced in these containers expressed a better performance in relation to root collar diameter and root dry mass

    Affinity purification of bacterial outer membrane vesicles (OMVs) utilizing a His-tag mutant

    Get PDF
    To facilitate the rapid purification of bacterial outer membrane vesicles (OMVs), we developed two plasmid constructs that utilize a truncated, transmembrane protein to present an exterior histidine repeat sequence. We chose OmpA, a highly abundant porin protein, as the protein scaffold and utilized the lac promoter to allow for inducible control of the epitope-presenting construct. OMVs containing mutant OmpA-His6 were purified directly from Escherichia coli culture media on an immobilized metal affinity chromatography (IMAC) Ni-NTA resin. This enabling technology can be combined with other molecular tools directed at OMV packaging to facilitate the separation of modified/cargo-loaded OMV from their wt counterparts. In addition to numerous applications in the pharmaceutical and environmental remediation industries, this technology can be utilized to enhance basic research capabilities in the area of elucidating endogenous OMV function

    Acidente botrópico em um canino: abordagem terapêutica – relato de caso / Botropic accident in a canine: therapeutic approach – case report

    Acidentes com a serpente do gênero Bothrops são muito comuns em animais de companhia, devido a agressividade destas serpentes e a curiosidade dos pequenos animais, principalmente caninos. Estes animais peçonhentos possuem uma toxina que produz um efeito anticoagulante, vasculotóxico e nefrotóxico causando sinais clínicos graves em animais de companhia. Este trabalho tem como objetivo relatar um acidente botrópico em um canino fêmea sem raça definida, de dez anos de idade, pesando 19kg, apresentando sangramento na cavidade oral e dispneia. Logo no atendimento emergencial foi coletado exames de sangue e, ao eritrograma, evidenciou-se considerável trombocitopenia. Inicialmente foi realizado terapia de suporte com oxigenioterapia e fluidoterapia. Foi administrado soro antiofídico polivalente, sendo este essencial para melhora do quadro do paciente. Além disso, foi administrado analgésicos devido alto grau de algia do paciente. A antibioticoterapia realizada também foi indispensável no tratamento devido áreas necrosadas causadas pela picada, além de infecções secundárias. A administração de corticosteroides e pré infusão de soro antiofídico reduz reações imediatas, como dispneia, tosses, náuseas, pruridos e urticaria. Pode se concluir que a conduta clínica e terapêutica utilizada, baseada nos sinais clínicos apresentados e resultados de exames de sangue mostrou-se eficiente. O soro antiofídico polivalente foi capaz de neutralizar o veneno inoculado e a associação terapêutica utilizada foi fundamental para a melhora significativa do animal.
