Combining Active Learning and Mathematical Programming: a hybrid approach for Transprecision Computing

This paper explores the possibility of applying a hybrid approach between Active Learning and Mathematical Programming to Transprecision Computing. This would entail embedding a machine learning model trained by means of an Active Learning approach into an optimization model to automatically and intelligently tweak the representation of floating-point numerical data. This project aims to lower the energetic expenditure of every single intermediate computation in a given program, while also avoiding errors that are systematically introduced when manipulating variables using this technique, and ensure that they do not exceed a maximum acceptable error rate decided prior

Norwegian futurisms: posthumanism and the Norwegian nordic model in Tor Åge Bringsværd’s "Du og Jeg", "Alfred" and "Alfred 2.0"

In Norway, much of the Science Fiction published over the last two decades has been dystopian and focused on the future effects of climate change on society. In light of this trend, this article explores how the ecodystopian duology, “Du og jeg”, “Alfred: Et tidsbilde” (2020) and “Alfred 2.0” (2022), written by Tor Åge Bringsværd under the pseudonym Edgar Burås, reflects on and criticizes the Norwegian Nordic model, particularly in relation to Norway’s oil wealth, social welfare, consumerism, and ecological concerns. As both novels mobilize characters and technologies that blur and confuse the boundaries of the human, the posthumanist theories of Donna Haraway are utilized in interpreting their cultural and socio-political symbolism. Additionally, these novels also serve as an intertextual update to Astrid Lindgren’s “Emil i Lönnebergaseries” (1963-1970), with the traditional boundaries of familial relationships pushed into posthuman notions of gender, age, and species. This article ultimately argues that the ecodystopian setting and posthuman characters posit an intersectional diversity and multispecies kinship that challenge notions of ecological and social sustainability in theNorwegian Nordic model. This article begins by introducing Bringsværd and the core texts, then concretizes the Norwegian Nordic model and explores the ecodystopian setting in light of neoliberalism and nationalism, and concludes with a discussion of posthumanism and intertextuality.En Noruega, gran parte de la ciencia ficción publicada en las últimas dos décadas ha sidodistópica y se ha centrado en los efectos futuros del cambio climático en la sociedad. A la luz de esta tendencia, este artículo explora cómo la duología ecodistópica, “Du og jeg”, “Alfred: Et tidsbilde” (2020) y “Alfred 2.0” (2022), escrita por Tor Åge Bringsværd bajo el seudónimo de Edgar Burås, reflexiona y critica el modelo nórdico noruego, particularmente en relación con la riqueza petrolera de Noruega, el bienestar social, el consumismo y las preocupaciones ecológicas. A medida que ambas novelas movilizan personajes y tecnologías que desdibujan y confunden los límites de lo humano, las teorías posthumanistas de Donna Haraway se utilizan para interpretar su simbolismo cultural y sociopolítico. Además, estas novelas también sirven como una actualización intertextual de la serie “Emil i Lönneberga” (1963-1970) de Astrid Lindgren con los límites tradicionales de las relaciones familiares empujados a nociones posthumanas de género, edad y especie. En última instancia, este artículo argumenta que el entorno ecodistópico y los personajes posthumanos postulan una diversidad interseccional y un parentesco multiespecie que desafían las nociones de sostenibilidad ecológica y social en el modelonórdico noruego. Este artículo comienza introduciendo a Bringsværd y los textos centrales, luego concreta el modelo nórdico noruego y explora el entorno ecodistópico a la luz del neoliberalismo y el nacionalismo, y concluye con una discusión sobre el posthumanismo y la intertextualidad

Pragmatic language disorder in Parkinson's disease and the potential effect of cognitive reserve

It is known that patients with Parkinson\u2019s Disease (PD) may show deficits in several areas of cognition, including speech and language abilities. One domain of particular interest is pragmatics, which refers to the capacity of using language in context for a successful communication. Several studies showed that some specific aspects of pragmatics \u2013 both in production and in comprehension \u2013 might be impaired in patients with PD. However, a clear picture of pragmatic abilities in PD is still missing, as most of the existing studies focused on specific aspects of the pragmatic competence rather than on sketching a complete pragmatic profile. Moreover, little is known on the potential role of protective factors in compensating the decline of communicative skills as the disease progresses. The present study has two aims: (1) to provide a complete picture of pragmatic abilities in patients with PD, by using a comprehensive battery (Assessment of Pragmatic Abilities and Cognitive Substrates, APACS) and by investigating the relationship with other aspects of cognitive functioning (e.g., working memory and Theory of Mind) and (2) to investigate whether Cognitive Reserve, i.e., the resilience to cognitive impairment provided by life experiences and activities, may compensate for the progressive pragmatic deficits in PD. We found that patients with PD, compared to healthy matched controls, had worse performance in discourse production and in the description of scenes, and that these impairments were tightly correlated with the severity of motor impairment, suggesting reduced intentionality of engaging in a communicative exchange. Patients with PD showed also an impairment in comprehending texts and humor, suggesting a problem in inferring from stories, which was related to general cognitive impairment. Notably, we did not find any significant difference between patients and controls in figurative language comprehension, a domain that is commonly impaired in other neurodegenerative diseases. This might be indicative of a specific profile of pragmatic impairment in patients with PD, worth of further investigation. Finally, Cognitive Reserve measures showed a high degree of association with pragmatic comprehension abilities, suggesting that the modification of life-styles could be a good candidate for compensating the possible problems in understanding the pragmatic aspects of language experienced by patients with PD

When Dancers Are Butterflies: How the Brain Understands Metaphors

When we speak, we often say things that are dierent from what we actually mean. For example, at a ballet, we might say that the dancers are butterflies. Dancers are not really butterflies, but this statement is not a lie; it is a metaphor. A metaphor is a figure of speech quite common in our everyday language and in books. In this article, we explain what metaphors are, why we use them, and what happens in our brains when we must understand a metaphor. Understanding metaphors requires a lot of brain work, which is why it is not always easy. Some people might find metaphors particularly diffcult to understand, for example, very young children and people who are autistic. At the end of the article, we suggest things that teachers and speech and language therapists can do to help those who have diffculty understanding metaphors.publishedVersio

Redes observação e a evolução tecnológica contribuindo para o desenvolvimento de modelos matemáticos na Meteorologia no século XX.

O objetivo deste trabalho é promover uma reflexão relacionada às características da evolução científica e institucional do campo científico da Meteorologia que possibilitaram, a partir de meados do século XX, a utilização de modelos matemáticos para fins de previsão do tempo. A Meteorologia é uma ciência relativamente jovem, se comparada à Matemática ou à Física, e que tem ganhado destaque desde a última metade do século XX. Alguns historiadores apontam que, antes do advento dos computadores e da ameaça do aquecimento global, a Meteorologia não possuia um carisma e uma velocidade de progresso que pudesse atrair eventuais historiadores. No entanto, a própria significância das preocupações sociais com o clima e suas alterações que marcaram a segunda metade do século XX, acabaram por gerar interesse pelas análises históricas relacionadas à Meteorologia. Estas análises apontam a especial relevância da evolução/ revolução tecnológica ocorrida no século XVII, com a invenção de vários instrumentos de medição como o barômetro e ou termômetro que permitiram que a Meteorologia passasse a ser uma ciência de bases quantitativas. No século XIX, a Meteorologia teve novo impulso com a invenção de instrumentos mais modernos para medição e do telégrafo aliada à sua ampla utilização por redes de observação meteorológica. Estas condições tornaram possível a geração de mapas sinópticos de previsão e a criação de sistemas de monitoramento e alarmes. Com isto, os serviços meteorológicos passaram a chamar a atenção dos Estados Nacionais. A evolução tecnológica e as formas institucionais criadas para o fornecimento de serviços meteorológicos - notadamente marcadas pelas redes de observação apoiadas pelo telégrafo - fornecem elementos para entender a evolução das técnicas utilizadas para atividades de previsão do tempo nos séculos XIX e XX. No século XX, a evolução tecnológica, calcada no desenvolvimento de tecnologias de informação e comunicação, permitiu o desenvolvimento de modelos matemáticos de previsão do tempo. O desenvolvimento do computador ENIAC, na década de 1950, possibilitou o cálculo da primeira previsão numérica do tempo. Este trabalho apresenta, sob uma forma revisional, o contexto tecnológico, organizacional e histórico que criou condições para a consolidação dos modelos de previsão numérica no campo da Meteorologia.Simpósio temático "Ciência&Tecnologia-Sociedade-História: Abordagens construtivistas"

The role of literal meaning in figurative language comprehension : evidence from masked priming ERP

The role of literal meaning during the construction of meaning that goes beyond pure literal composition was investigated by combining cross-modal masked priming and ERPs. This experimental design was chosen to compare two conflicting theoretical positions on this topic. The indirect access account claims that literal aspects are processed first, and additional meaning components are computed only if no satisfactory interpretation is reached. In contrast, the direct access approach argues that figurative aspects can be accessed immediately. We presented metaphors (These lawyers are hyenas, Experiment 1a and 1b) and producer-for-product metonymies (The boy read Böll, Experiment 2a and 2b) with and without a prime word that was semantically relevant to the literal meaning of the target word (furry and talented, respectively). In the presentation without priming, metaphors revealed a biphasic N400-Late Positivity pattern, while metonymies showed an N400 only. We interpret the findings within a two-phase language architecture where contextual expectations guide initial access (N400) and precede pragmatic adjustment resulting in reconceptualization (Late Positivity). With masked priming, the N400-difference was reduced for metaphors and vanished for metonymies. This speaks against the direct access view that predicts a facilitating effect for the literal condition only and hence would predict the N400-difference to increase. The results are more consistent with indirect access accounts that argue for facilitation effects for both conditions and consequently for consistent or even smaller N400-amplitude differences. This combined masked priming ERP paradigm therefore yields new insights into the role of literal meaning in the online composition of figurative language
