The use of automation in cars is increasing. In future vehicles, drivers will no longer be in charge of the main driving task and may be allowed to perform a secondary task. However, they might be requested to regain control of the car if a hazardous situation occurs. Performing a secondary task might increase drivers' mental workload and consequently decrease the takeover performance if the workload level exceeds a certain threshold. Knowledge about the driver's mental state might hence be useful (...) for increasing safety in conditionally automated vehicles. Measuring drivers' workload continuously is essential to support the driver and hence limit the number of accidents in takeover situations. This goal can be achieved using machine learning techniques to evaluate and classify the drivers' workload in real-time. To evaluate the usefulness of physiological data as an indicator for workload in conditionally automated driving, three physiological signals from 90 subjects were collected during 25 min of automated driving in a fixed-base simulator. Half of the participants performed a verbal cognitive task to induce mental workload while the other half only had to monitor the environment of the car. Three classifiers, sensor fusion and levels of data segmentation were compared. Results show that the best model was able to successfully classify the condition of the driver with an accuracy of 95%. In some cases, the model benefited from sensors' fusion. Increasing the segmentation level increased the performance of the model for windows smaller than 4 min, but decreased for windows larger than 4 min. In conclusion, the study showed that a high level of drivers' mental workload can be accurately detected while driving in conditional automation based on 4-min recordings of respiration and skin conductance.

La riflessione sullo statuto epistemologico e sul funzionamento politico del discorso biologico – nel suo carattere eterogeneo, plurale e conflittuale – è un tema centrale nelle opere di Michel Foucault e Georges Canguilhem. A partire dall’analisi delle relazioni e delle tensioni tra i loro orientamenti teorici, questo studio propone una rilettura critica delle loro ricerche, integrandole e utilizzandole nei dibattiti epistemologici e politici contemporanei. In tal senso, la filosofia biologica di Canguilhem permette di riesaminare la concezione foucaultiana della storia, della (...) società, della soggettività, della tecnica, dell’ambiente, e di reinterrogare in una prospettiva socio-ecologica ed eco-storica lo spazio d’intervento delle tecnologie biopolitiche.

Au cours du xix e siècle, les théories transformistes et l’évolutionnisme permettaient de penser d’une nouvelle manière l’historicité de la nature et de la vie, y compris celle de l’homme. Historisation de la nature et naturalisation de l’homme marchent ensemble, mais la forme attribuée à la temporalité naturelle et la place de l’homme dans l’histoire de la vie restent sujets à des conceptions fort différentes dans les champs scientifiques et philosophiques et continuent à être objet de discussion tout au long (...) du xx e siècle. La question de l’articulation entre l’historicité biologique et anthropologique joue également un rôle décisif dans les œuvres de Friedrich Nietzsche et de Michel Foucault. Nous essayerons ici de contextualiser leurs réflexions à ce sujet, de montrer leurs relations et leurs spécificités, ainsi que leur actualité. (shrink)

In this article I analyze the justification of rawlsian anti-perfectionism, present in both A Theory of Justice and Political Liberalism. My aim is to show how justice as fairness, Rawls's conception of justice, lacks stability because of it. As an alternative to his anti-perfectionism, I propose, in the second part, the idea of progress as practical perfectionism by John Dewey. I argue that a perfectionist liberalism of this kind does not undermine reasonable pluralism as Rawls argued. Also I argue that (...) it is indispensable to establish a liberal society that is stable. In the end, I briefly show how the private sphere could be affected once the idea of progress is part of a conception of liberal justice. (shrink)

En este artículo, mostramos ciertos supuestos no explicitados en la noción de individuo humano en la que se basan los enfoques teóricos de la neuroeconomía y la economía conductual para desarrollar sus programas de investigación e intervención. También abordamos los compromisos epistemológicos, ideológicos y políticos desde los cuales conciben, estudian e intervienen en la conducta humana. En lugar de un individuo producto de un proceso de socialización, lo que se presenta es un cerebro aislado con numerosas funciones cognitivas atribuidas, cuya (...) conducta puede ser alterada debido a “accidentes” en su evolución como órgano rector del comportamiento. Este enfoque permite la construcción de propuestas de políticas públicas basadas en el llamado “paternalismo libertario”. Se destaca un potencial mecanismo de control cuyo objetivo es configurar los distintos espacios de la vida cotidiana de los individuos de manera que sus conductas agregadas se alineen lo más posible con los entes racionales ideales del modelo económico neoclásico.

O presente artigo faz uma breve apreciação do texto La réalité et son ombre, de E. Levinas, especificamente acerca de sua consideração em torno do valor da arte como possibilidade de transcendência. Se, em obras posteriores, Levinas ainda permanece de certo modo econômico, e às vezes ambíguo, sobre a questão, neste texto sua crítica permanece dura e direta. Aqui se discute a relação entre imagem, exterioridade e o real. A obra de arte fala? Exigiria uma resposta e seria ética? Neste (...) texto de 1948, encontramos uma série de argumentos, no seu diálogo com a arte, que já pre-param, ou anunciam, o que posteriormente virá como a transcedência do Rosto “que vai além da forma que o delimita”. Palavras-chave: Arte, transcendência, exterioridade, imagem, realidade. (shrink)

Resumo Este artigo procura apresentar e discutir tentativas recentes em filosofia social de analisar e interpretar o capitalismo, a partir de uma perspectiva praxeológica. O practice turn em teoria social procurou superar o dualismo entre agência e estrutura, ou entre ação e sistema, por meio da noção de prática social. Seria possível então interpretar o capitalismo como um tipo especifico de prática social? Para tentar encaminhar essa questão, explicita-se brevemente, em um primeiro momento, em que consiste o practice turn em (...) teoria social. Num segundo momento, analisa-se e se discute a proposta de Rahel Jaeggi de conceber a economia como uma rede de práticas sociais. Em seguida, expõe-se e se avalia a tentativa de Christian Lotz em ver, no dinheiro, a chave para compreender aquilo que ele chama de esquema capitalista. Por fim, conclui-se, chamando a atenção para os potenciais e desafios ligados ao empreendimento de interpretar o capitalismo em função de uma teoria da prática, sugerindo que um aprofundamento na análise da imaginação especificamente capitalista, vinculando-a com a típica plasticidade e diversidade do capitalismo, possa ajudar a avançar nesse campo.This paper aims to present and discuss recent attempts in social philosophy to analyze and interpret capitalism from a praxeological perspective. The practice turn in social theory sought to overcome the dualism between agency and structure, or between action and system, through the notion of social practice. Is it then possible to interpret capitalism as a specific type of social practice? To try to address this question, I briefly introduce, in a first moment, the practice turn in social theory. In a second moment, I analyze and discuss Rahel Jaeggi’s proposal to conceive the economy as a network of social practices. I then explain and evaluate Christian Lotz’s attempt to see money as the key to understanding what he names as “the capitalist schema”. Finally, I conclude by drawing attention to the potentials and challenges of interpreting capitalism as a social practice, suggesting that a deeper analysis of specifically capitalist imagination, linking it with the typical plasticity and diversity of capitalism, may help to move forward in this field.

A IMPORTÂNCIA DA BOA-FÉ NAS RELAÇÕES DE CONSUMO.

The interest in what can be considered 'posthumanism' has surged over the past few years. There is no surprise as to why, given the urgency and immanence of a likely sixth mass extinction event, and the catastrophic consequences of global warming. These processes, all of which fundamentally rest on the foundations of human practices and abuses, are forcing us to rethink our place in existence. The foundations of this position have a history firmly rooted in the daily practices and beliefs (...) of Western cultures. The Contemporary Posthuman confronts these assumptions of truth, head-on. The author follows his conceptual journey with practical steps for putting his philosophy into practice, by drawing on philosophy, design, art, and architecture. (shrink)

Organization figures centrally in the understanding of biological systems advanced by both new mechanists and proponents of the autonomy framework. The new mechanists focus on how components of mechanisms are organized to produce a phenomenon and emphasize productive continuity between these components. The autonomy framework focuses on how the components of a biological system are organized in such a way that they contribute to the maintenance of the organisms that produce them. In this paper we analyze and compare these two (...) accounts of organization and argue that understanding biological organisms as cohesively integrated systems benefits from insights from both. To bring together the two accounts, we focus on the notions of control and regulation as bridge concepts. We start from a characterization of biological mechanisms in terms of constraints and focus on a specific type of mechanism, control mechanisms, that operate on other mechanisms on the basis of measurements of variables in the system and its environment. Control mechanisms are characterized by their own set of constraints that enable them to sense conditions, convey signals, and effect changes on constraints in the controlled mechanism. They thereby allow living organisms to adapt to internal and external variations and to coordinate their parts in such a manner as to maintain viability. Because living organisms contain a vast number of control mechanisms, a central challenge is to understand how they are themselves organized. With the support of examples from both unicellular and multicellular systems we argue that control mechanisms are organized heterarchically, and we discuss how this type of control architecture can, without invoking top-down and centralized forms of organizations, succeed in coordinating internal activities of organisms.

Living organisms act as integrated wholes to maintain themselves. Individual actions can each be explained by characterizing the mechanisms that perform the activity. But these alone do not explain how various activities are coordinated and performed versatilely. We argue that this depends on a specific type of mechanism, a control mechanism. We develop an account of control by examining several extensively studied control mechanisms operative in the bacterium E. coli. On our analysis, what distinguishes a control mechanism from other mechanisms (...) is that it relies on measuring one or more variables, which results in setting constraints in the control mechanism that determine its action on flexible constraints in other mechanisms. In the most basic arrangement, the measurement process directly determines the action of the control mechanism, but in more complex arrangements signals mediate between measurements and effectors. This opens the possibility of multiple responses to the same measurement and responses based on multiple measurements. It also allows crosstalk, resulting in networks of control mechanisms. Such networks integrate the behaviors of the organism but also present a challenge in tailoring responses to particular measurements. We discuss how integrated activity can still result in differential, versatile, responses. (shrink)

Biological regulation is what allows an organism to handle the effects of a perturbation, modulating its own constitutive dynamics in response to particular changes in internal and external conditions. With the central focus of analysis on the case of minimal living systems, we argue that regulation consists in a specific form of second-order control, exerted over the core regime of production and maintenance of the components that actually put together the organism. The main argument is that regulation requires a distinctive (...) architecture of functional relationships, and specifically the action of a dedicated subsystem whose activity is dynamically decoupled from that of the constitutive regime. We distinguish between two major ways in which control mechanisms contribute to the maintenance of a biological organisation in response to internal and external perturbations: dynamic stability and regulation. Based on this distinction an explicit definition and a set of organisational requirements for regulation are provided, and thoroughly illustrated through the examples of bacterial chemotaxis and the lac-operon. The analysis enables us to mark out the differences between regulation and closely related concepts such as feedback, robustness and homeostasis. (shrink)

Despite numerous and increasing attempts to define what life is, there is no consensus on necessary and sufficient conditions for life. Accordingly, some scholars have questioned the value of definitions of life and encouraged scientists and philosophers alike to discard the project. As an alternative to this pessimistic conclusion, we argue that critically rethinking the nature and uses of definitions can provide new insights into the epistemic roles of definitions of life for different research practices. This paper examines the possible (...) contributions of definitions of life in scientific domains where such definitions are used most (e.g., Synthetic Biology, Origins of Life, Alife, and Astrobiology). Rather than as classificatory tools for demarcation of natural kinds, we highlight the pragmatic utility of what we call operational definitions that serve as theoretical and epistemic tools in scientific practice. In particular, we examine contexts where definitions integrate criteria for life into theoretical models that involve or enable observable operations. We show how these definitions of life play important roles in influencing research agendas and evaluating results, and we argue that to discard the project of defining life is neither sufficiently motivated, nor possible without dismissing important theoretical and practical research.
