Color-motion asynchrony (CMA) refers to an apparent lag of direction of motion when a dynamic stimulus changes both color and direction at the same time. The subjective order of simultaneous events, however, is not only perceptual but also subject to illusions during voluntary actions. Self-initiated actions, for example, seem to precede their sensory outcomes following an adaptation to a delay between the action and the sensory feedback. Here, we demonstrate that the extent of the apparent asynchrony can be substantially reduced (...) when direction change is induced by a voluntary key press following a delay adaptation regime. We also show that the reduced color-motion asynchrony effect size following a motor-sensory recalibration is not a result of a change in the onset of perceived direction change relative to that of the color. This is particularly important as it implies, for the first time in the literature, that voluntary action is not only important in forming action-sensory outcome associations but may also act as a binding factor between the two perceptual features of a sensory event.

In this article, we introduce and demonstrate the concept-metaphor of broken data. In doing so, we advance critical discussions of digital data by accounting for how data might be in processes of decay, making, repair, re-making and growth, which are inextricable from the ongoing forms of creativity that stem from everyday contingencies and improvisatory human activity. We build and demonstrate our argument through three examples drawn from mundane everyday activity: the incompleteness, inaccuracy and dispersed nature of personal self-tracking data; the (...) data cleaning and repair processes of Big Data analysis and how data can turn into noise and vice versa when they are transduced into sound within practices of music production and sound art. This, we argue is a necessary step for considering the meaning and implications of data as it is increasingly mobilised in ways that impact society and our everyday worlds. (shrink)

This study analyses joint decisions. Drawing on video-recorded planning meetings in a workplace context as data, and on conversation analysis as a method, I investigate what is needed for a proposal to get turned into a joint decision: How do people negotiate the outcome of the decision-making processes in terms of whether they indeed comprise new decisions and whether these decisions are really joint ones? This study identifies three essential components in arriving at joint decisions, and discusses two other possible (...) outcomes of decision-making processes – non-decisions and unilateral decisions – as being a direct result of the deployment of the same components. These observations help explain the exact mechanisms involved in approving and rejecting proposals in joint decision-making settings, as well as the ways in which people may negotiate their rights and obligations to participate in decision-making processes.

Expertise is commonly viewed as a professionalized competence in a specific field. Expert professional identities are produced and reproduced through professional training and other socialization mechanisms, which work to generate for a specific group of individuals a specific set of expert skills and knowledge. In this paper, I examine participants’ orientations to their distinct expert professional identities from the perspective of deontic authority. Drawing on 15 video-recorded church workplace meetings between pastors and cantors as data, and conversation analysis as a (...) theoretical and methodological framework, I analyze situations where a non-expert participant makes a proposal that the expert participant orients to as reasonable to comply with. Specifically, I demonstrate how the expert participants respond to these proposals with displays of deontic authority, arguably in an attempt to maintain their expert identities in the face of their de facto compliance with the proposals. In these situations, the expert participants are shown to invoke a past decision of their own, a future decision of their own, or a pattern that is beyond both participants’ control. Each of these practices involves the expert participant balancing resistance and compliance by minimally acknowledging the content of the non-expert participant’s proposal, while excluding the non-expert from those who have deontic authority in the matter. In so doing, the expert speaker implies that the non-expert proposal speaker lacks procedural knowledge about the specific matters about which it is relevant to make proposals to experts and access to the distinct experiential perspective that characterizes expert perception of things. It is thus argued that, in this context, the mere claims of deontic authority, produced without any substantial displays of expert knowledge, can serve the maintenance of expert professional identities.

Although number sentences are ostensibly simple, familiar, and applicable, the justification for our arithmetical beliefs has been considered mysterious by the philosophical tradition. In this paper, I argue that such a mystery is due to a preconception of two realities, one mathematical and one nonmathematical, which are alien to each other. My proposal shows that the theory of numbers as properties entails a homogeneous domain in which arithmetical and nonmathematical truth occur. As a result, the possibility of arithmetical knowledge is (...) simply a consequence of the possibility of ordinary knowledge. (shrink)

In this paper, we examine two conceptions of the application of logic and assess their comparative merits. The first is a platonist monist conception that characterizes the logical consequence relation as an abstract relation among propositions. We argue that this proposal, which insists on logic’s topic neutrality, accommodates very well the objectivity of logic. From this perspective, there are no constraints on particular topics. As a result, we have the universality that allows us to go through a wide scope of (...) contexts where logic is applied. In contrast, a non-platonist pluralist conception is examined, and it characterizes the variety of logical consequence relations as concrete, context-dependent in particular cases, and topic-dependent. As will become clear, this conception is particularly well suited to make room for the applications of logic. We conclude that, in order to solve the ontological debate about logic, we need to go beyond its applications. (shrink)

The so-called ‘Right to Be Forgotten’ cases have been provoked by people’s desires to make their own determinations about what personal information is accessible online to others (and when, and how) in a world of data permanence. Legally at stake is how personhood is defined and defended. Thus far, European law has primarily concerned itself with the delisting of ‘data subjects’ from search results and the deletion or anonymization of personal information from and by search engine operators. As a result, (...) personhood has fallen into a kind of legislative void [ 43 ] I argue that this void is engendered by an old friction between the traditional Western secularist cognitive models that have formed the skeleton of Western law and the pulsing flesh of living human subject creation that pushes back against it. At the very least, the digital immortality of our images, voices, words and more, are bringing forth a variety of aspects of our ‘person.’ Meanwhile, religious worldviews have long understood and made use of phenomenological ideas of human becoming and transcendence that are far more congruous with how—even modern secular—people make meaning of their lives and self-creation, and how they think of posthumous existence. Moving through and with some of the most recent thinking in philosophy, anthropology, and cognitive science, I will develop the argument that human subjectivity is not only impossible to limit to the body, but that a radicalized ecological view is the only one that can ‘save’ us.

What does it mean to spatialize food? Why combine such an analysis with law, or with signs and spaces? Leveraging Peircean-inspired legal semiotic theory, the spatialized nature of food will serve as a porthole through which a semiotic view of the spatial dimensions of legal experience can be discerned and elaborated. Specifically, case studies of the simultaneously material and immaterial aspects of food will support an analysis that seeks to open avenues of conceptualization regarding categories. The semiotic nature of both (...) food and law will drive a discussion of the “dis-composition” of categories. Though such an effort may appear overly scholarly and far from pragmatic, exactly the opposite claim will be made. Case studies such as that of the “Meatball Wars” will illustrate in plain terms how subject position struggles for space cannot be adequately addressed within traditional disciplinary boundaries. The essay will conclude with a demonstration of how a “discomposing” semiotic approach has the potential to serve as a means of enabling conflict resolution on a broader scale. The overall investigation is motivated by the struggle within academia – seen across the humanities – to rethink traditional foundational assumptions and dichotomies. The argument seeks to ground itself in the interconnectedness increasingly advanced, joining scholars who insist on the importance of anthro-historical context, local particulars, and the impossibility of assuming an objective position that can coolly observe phenomena from “outside.”.

Sexual consent is advocated around the world to reduce sexual assault. The widespread affirmative consent model emphasizes a need for unambiguous consent. In this paper, we contribute to a deeper understanding of how ambiguities in the initiations of sexual activities are routinely solved to achieve consent. Drawing on conversation analytic research on joint decision-making, and a dataset of 80 cases of sexual initiation in contemporary TV-series and movies, we investigate the interactional practices by which sexual activities are presented as consensual (...) and how consent is achieved across sequences of interaction. We found there to be social advantages of synchronous initiation, compared to sequential verbal initiations, which were associated with various social vulnerabilities. These vulnerabilities could however be circumvented by two practices, each of which made use of a distinct combination of verbal and embodied resources. While ambiguities exist, our results oppose the idea of sexual consent as a practically hopeless and awkward endeavor. Instead, consent consists of joint action that is achieved through recognizable and systematic ways. (shrink)

Resumen Este trabajo intenta esbozar ciertas reflexiones en torno al papel de los afectos en la práctica de la autotraducción en la poesía mapuches. Vemos en el “giro afectivo” una posibilidad de comprender la producción literaria bilingüe de autores mapuches como un proyecto ético de reapropiación lingüística y de transgresión de límites culturales originado en afectos de “pulsión genealógica” que ponen en cuestión la autoridad de la lengua del colonizador, a la vez que resultan en la generación de los llamados (...) “afectos activos”, propios de un aumento del grado de potencia expresiva y de agenciamiento de los sujetos. Para ello trazaremos una cartografía de conceptos de distintos pensadores que han reflexionado acerca de los afectos y la lengua, desde Jacques Derrida a Gloria Anzaldúa, pasando por el ineludible Gilles Deleuze en su estudio de los afectos en la Ética de Baruch Spinoza. Asimismo, pondremos estos conceptos en diálogo con las propias reflexiones de varios de autores mapuches: Liliana Ancalao, Adriana Paredes Pinda, María Teresa Panchillo, Leonel Lienlaf y Elicura Chihuailaf.In this work we wish to analyze the role of affects in self-translation in Mapuche poetry. We see in the “affective turn” a possibility to understand the bilingual literary production of Mapuche authors as an ethical project of linguistic reappropriation and transgression of cultural limits originated in affects of “genealogical drive” that question the authority of the language of the colonizer, as well as resulting in the generation of “active affects”, inherent to the increase of the degree of expressive potency of the subjects. For this purpose, we set out to trace a cartography of concepts by different thinkers who have reflected upon the relationship between affects and language, from Jacques Derrida to Gloria Anzaldúa, as well as the inescapable contributions of Gilles Deleuze on the study of affects in Spinoza’s Ethics. Also, we will link such concepts with the reflections of five Mapuche poets, Liliana Ancalao, Adriana Paredes Pinda, María Teresa Panchillo, Leonel Lienlaf and Elicura Chihuailaf. (shrink)

This paper examines two alleged limitations in the use of formal languages: on the one hand, the trade-offs between expressive and inferential power, and on the other, the phenomenon of system imprisonment. After reconceptualizing the issue, we consider the role played by modality in the understanding of certain aspects of mathematical structures and argue for its centrality.

All effective communication is based on the participants trusting that they share their basic orientations to the world – that is, they have a common ground. In this paper, however, we examine situations in which such trust is lacking. Drawing on conversation–analytic methodology and on 30 hours of video data featuring persons with dementia and their caregivers in a Swedish-language daycare center in Finland, we consider some of the social consequences resulting from a lack of trust. Our analysis focused on (...) three different interactional contexts, highlighting the relevance of different facets of the participants’ common ground. These facets are anchored in the deontic, epistemic, and emotional orders, respectively. We show that, with regard to each order, a lack of trust in the existence of common ground has drastic consequences, leading to problems related to getting one’s will acknowledged, a scarcity of conversational partners, and a lack of resources to maintain affection.

How do professionals working in pre-implantation genetic diagnosis reflect upon their decision making with regard to ethical challenges arising in everyday practice? Two focus group discussions were held with staff of reproductive genetic clinics: one in Utrecht with PGD-professionals from Dutch PGD-centres and one in Prague with PGD-professionals working in centres in different European countries. Both meetings consisted of two parts, exploring participants’ views regarding treatment requests for conditions that may not fulfill traditional indications criteria for PGD, and treatment and (...) transfer requests involving welfare-of-the-child considerations. There was general support for the view that people who come for PGD will have their own good reasons to consider the condition they wish to avoid as serious. But whereas PGD-professionals in the international group tended to stress the applicants’ legal right to eventually have the treatment they want, participants in the Dutch group sketched a picture of shared decision-making, where professionals would go ahead with treatment in cases where they are able to understand the reasonableness of the request in the light of the couple’s reproductive history or family experience. In the international focus group there was little support for guidance stating that welfare-of-the child considerations should be taken into account. This was different in the Dutch focus group, where shared decision-making also had the role of reassuring professionals that applicants had adequately considered possible implications for the welfare of the child.

Las secciones y divisiones dedicadas a la inteligencia y seguimiento político y social son centrales en la historia de las policías argentinas. La historiografía reciente ha destacado la complejidad de interpretar las políticas estatales de seguridad y sus transformaciones en el tiempo como producto de un proceso de larga duración.

Un (...) abordaje que radica en ponderar las especificidades institucionales propias de un período escasamente transitado para estos escenarios a partir de tres ejes: primero, recompone el proceso de burocratización interno que transitarían ambas reparticiones producto de estas tareas. Segundo, estas secciones construyeron una sólida tradición de información materializada en informes, expedientes y prontuarios. En ese sentido, se pone el foco en los agentes que se configuraron como un grupo de “expertos” en su producción como en las lógicas para la recolección de información. Por último, se incursiona en los sentidos otorgados a los actores “observados”. (shrink)

Misinformation about the novel coronavirus is a pressing societal challenge. Across two studies, one preregistered, we assess the efficacy of two ‘prebunking’ interventions aimed at improving people’s ability to spot manipulation techniques commonly used in COVID-19 misinformation across three different languages. We find that Go Viral!, a novel five-minute browser game, increases the perceived manipulativeness of misinformation about COVID-19, improves people’s attitudinal certainty in their ability to spot misinformation and reduces self-reported willingness to share misinformation with others. The first two (...) effects remain significant for at least one week after gameplay. We also find that reading real-world infographics from UNESCO improves people’s ability and confidence in spotting COVID-19 misinformation. Limitations and implications for fake news interventions are discussed. (shrink)

From March to September 2020, researchers working at a biomedical scientific campus in Spain faced two lockdowns and various mobility restrictions that affected their social and professional lifestyles. The working group “Women in Science,” which acts as an independent observatory of scientific gender inequalities on campus launched an online survey to assess the impact of COVID-19 lockdowns on scientific activity, domestic and caregiving tasks, and psychological status. The survey revealed differences in scientific performance by gender: while male researchers participated in (...) a larger number of scientific activities for career development, female researchers performed more invisible scientific tasks, including peer review or outreach activities. Mental impact was greater in researchers caring for children or dependents, and this was aggravated for women. Results spot a disproportionate impact of COVID-19 lockdowns on female scientific career development, and urges for equity measures to mitigate the consequences of an increase in the gender gap in biomedical sciences for current and future pandemics.

IntroductionThe assessments of the motor symptoms in Parkinson’s disease are usually limited to clinical rating scales, and it depends on the clinician’s experience. This study aims to propose a machine learning technique algorithm using the variables from upper and lower limbs, to classify people with PD from healthy people, using data from a portable low-cost device. And can be used to support the diagnosis and follow-up of patients in developing countries and remote areas.MethodsWe used Kinect®eMotion system to capture the spatiotemporal (...) gait data from 30 patients with PD and 30 healthy age-matched controls in three walking trials. First, a correlation matrix was made using the variables of upper and lower limbs. After this, we applied a backward feature selection model using R and Python to determine the most relevant variables. Three further analyses were done using variables selected from backward feature selection model, movement disorders specialist, and all the variables from the dataset. We ran seven machine learning models for each model. Dataset was divided 80% for algorithm training and 20% for evaluation. Finally, a causal inference model using the DoWhy library was performed on Dataset B due to its accuracy and simplicity.ResultsThe Random Forest model is the most accurate for all three variable Datasets followed by the support vector machine. The CIM shows a relation between leg variables and the arms swing asymmetry and a proportional relationship between ASA and the diagnosis of PD with a robust estimator.ConclusionsMachine learning techniques based on objective measures using portable low-cost devices are useful and accurate to classify patients with Parkinson’s disease. This method can be used to evaluate patients remotely and help clinicians make decisions regarding follow-up and treatment. (shrink)

Abstract. The notion of similarity has been studied in many areas of Computer Science; in a general sense, this concept is defined to provide a measure of the semantic equivalence between two pieces of knowledge, expressing how “close” their meaning can be regarded. In this work, we study similarity as a tool useful to improve the representation of arguments, the interpretation of the relations between arguments, and the semantic evaluation associated with the arguments in the argumentative process. In this direction, (...) we present a novel mechanism to determine the similarity between two arguments based on descriptors representing particular aspects associated with these arguments. This mechanism involves a comparison process influenced by the context in which the process develops, where this context provides the relevant aspects that need to be analyzed in the application domain. Then, we use this similarity measure as a quantity to compute the result of attacks and supports in the argumentation process. These valuations, applied to a Bipolar Argumentation Frameworks, allowed us to refine the argument relations, providing the tools to establish a family of new argumentation semantics that considers the similarity between arguments as a crucial part for the argumentation process.

We present a novel argumentation-based method for finding and analyzing communities in social media on the Web, where a community is regarded as a set of supported opinions that might be in conflict. Based on their stance, we identify argumentative coalitions to define them; then, we apply a similarity-based evaluation method over the set of arguments in the coalition to determine the level of cohesion inherent to each community, classifying them appropriately. Introducing conflict points and attacks between coalitions based on (...) argumentative (dis)similarities to model the interaction between communities leads to considering a meta-argumentation framework where the set of coalitions plays the role of the set of arguments and where the attack relation between the coalitions is assigned a particular strength which is inherited from the arguments belonging to the coalition. Various semantics are introduced to consider attacks’ strength to particularize the effect of the new perspective. Finally, we analyze a case study where all the elements of the formal construction of the formalism are exercised. (shrink)

Melisa Vivanco objects to my theory of the Arabic numerals in Roads to Reference that the reference fixing procedure that I postulate doesn’t exploit the morphological structure of the Arabic numerals, but it should. Against Vivanco, I argue that the procedure in question does exploit the morphological structure of the numerals in an essential way.
