Where are you? A heideggerian analysis of the mobile phone

This paper is an attempt at clarifying the essential contours of the phenomenon that grounds the developments in contemporary mobile communication: the mobile phone. In so doing our investigation intends to answer the question of what a mobile phone is as such. The paper presents a description of the mobile phone and its contextualisation within some of the works of Martin Heidegger (1889-1976), seeking to uncover the essential mode in which a mobile phone is what it is. Grounding our analysis on the ontology of Heidegger’s Being and Time (Heidegger 1962), we claim that the mobile phone will only show itself as what it is in its being in-the-world where mobile phones are what they are. This analysis is complemented by an exploration of the relevance of another of Heidegger’s notions, that of Ge-stell (Heidegger 1977) as the essence of modern technology, for the understanding of human involvement with mobile phones. Against this ontological background, our analysis points out being-with, bringing together and timing as the essential contours of the mobile phone, all of these suggesting the deeper notions of actual situation and of disembodiment.Este paper investiga os contornos essenciais do fenómeno sobre o qual assentam os actuais desenvolvimentos na comunicação móvel: o telemóvel. Assim, pretende-se responder à pergunta: o que é, enquanto tal, um telemóvel? O paper apresenta uma descrição fenomenológica do telemóvel, contextualizada por dois dos trabalhos de Martin Heidegger (1889-1976), tentando apontar o modo como no-mundo o telemóvel é o que é. Assentando a análise na ontologia de Heidegger apresentada em Ser e Tempo (Heidegger 1962 [1927]), propomos, neste artigo, que o telemóvel só se nos mostrará tal qual ele é desde que acedido no-mundo onde os telemóveis já são o que são. Esta análise é complementada por uma exploração de uma outra noção Heideggeriana, a de Ge-stell (Heidegger 1977) como essência da tecnologia moderna, visando desta forma obter uma melhor compreensão do envolvimento humano com os telemóveis. Neste contexto ontológico, a nossa investigação aponta as noções de ser-com, de juntar e de timing como contornos essenciais do telemóvel. Estas ideias, por sua vez, sugerem as noções mais fundas de momento e de descorporização como essenciais no fenómeno do telemóvel

Understanding the cap pillar II component -leader-: a counterfactual impact analysis of the rural development measure between 2011-2015 - measuring impact on European elections voting behavior

The Common Agricultural Policy is one of the EU’s largest and most important policies. LEADER, a part of the CAP located in Pillar II, is a bottom-up rural development program based on local stakeholder engagement. The effects of LEADER have been analyzed using a counterfactual impact evaluation employing the CBPS method and propensity score matching. Results are diverse, but in many cases, a significant impact of LEADER can be found. The outcome variables studied range from economic in nature to agritourism, voting behavior and demographics. Their relevance, especially in rural areas, is ever increasing and relevant for the EU’s future

A catarse do fogo: a simbologia do fogo nos ecrãs da televisão

Centring the analysis on the riots in Paris by the end of year of 2005, yet touching upon other recent scenes of fire in the news, this paper explores the meaning of fire at the television screens. It considers why one cannot get enough of watching a burning fireplace or, indeed, of watching fires at the TV screen? Because in a third order simulacra, fire is just information, we ask what do these flames on the screens inform us about? For answering this question, the paper looks at the role of fire, both as a symbol and as a medium, into a screened hiper-reality, contextualised by the abundance of the symbolic universe of the digital technological culture, namely the MTV global channel. Submitting that nowadays advertisement and the news form a hiper-real continuum that tells us who we are, this paper analyses the joining of a cool media, such as fire, with another cool media, such as television. In our approach we use Baudrillard’s notions of simulacra and symbolic exchange as well as some of their developments, namely the virtuality of screens and the idea of catastrophe as defence, in order to show that the fires on the screens are both a consequence and a cause of the hiper-real technological regime, as well as a paradoxical exchange that refuels the very hiper-real contemporary enframing.Centrando-se nos distúrbios de Novembro de 2005 em Paris, durante os quais foram queimados milhares de automóveis, este artigo propõe uma análise fenomenológica e semiótica do fogo nos ecrãs da televisão. Porque na terceira ordem de simulacro (Baudrillard, 2004/1981) o fogo na televisão é apenas informação, questionamo-nos sobre o que nos informam as chamas no ecrã? Hoje o fogo é tanto o símbolo que sempre foi, como um media para uma hiper-realidade ecranizada, contextualizada pela abundância de bens e pelo universo dos telemóveis, da MTV, da Internet e da publicidade. Neste artigo utilizamos algumas das noções desenvolvidas por Jean Baudrillard, como a troca simbólica e a sua interpretação de potlatch, e a concepção da catástrofe como defesa, para tentar mostrar como os fogos nos ecrãs da televisão são, simultaneamente, causa e consequência do regime hiper-real em que vivemos, bem como uma troca simbólica paradoxal que re-alimenta o enquadramento hiper-real da sociedade hiper-real do século xxi

Adaptive Testing of Computer Vision Models

Vision models often fail systematically on groups of data that share common semantic characteristics (e.g., rare objects or unusual scenes), but identifying these failure modes is a challenge. We introduce AdaVision, an interactive process for testing vision models which helps users identify and fix coherent failure modes. Given a natural language description of a coherent group, AdaVision retrieves relevant images from LAION-5B with CLIP. The user then labels a small amount of data for model correctness, which is used in successive retrieval rounds to hill-climb towards high-error regions, refining the group definition. Once a group is saturated, AdaVision uses GPT-3 to suggest new group descriptions for the user to explore. We demonstrate the usefulness and generality of AdaVision in user studies, where users find major bugs in state-of-the-art classification, object detection, and image captioning models. These user-discovered groups have failure rates 2-3x higher than those surfaced by automatic error clustering methods. Finally, finetuning on examples found with AdaVision fixes the discovered bugs when evaluated on unseen examples, without degrading in-distribution accuracy, and while also improving performance on out-of-distribution datasets.Comment: ICCV camera-read
