The present paper analyzes the self‐generated explanations (from talk‐aloud protocols) that “Good” and “Poor” students produce while studying worked‐out examples of mechanics problems, and their subsequent reliance on examples during problem solving. We find that “Good” students learn with understanding: They generate many explanations which refine and expand the conditions for the action parts of the example solutions, and relate these actions to principles in the text. These self‐explanations are guided by accurate monitoring of their own understanding and misunderstanding. Such (...) learning results in example‐independent knowledge and in a better understanding of the principles presented in the text. “Poor” students do not generate sufficient self‐explanations, monitor their learning inaccurately, and subsequently rely heavily on examples. We then discuss the role of self‐explanations in facilitating problem solving, as well as the adequacy of current AI models of explanation‐based learning to account for these psychological findings.

This paper aims to enhance security in IoT device networks through a visual tool that utilizes three projection techniques, including Beta Hebbian Learning (BHL), t-distributed Stochastic Neighbor Embedding (t-SNE) and ISOMAP, in order to facilitate the identification of network attacks by human experts. This work research begins with the creation of a testing environment with IoT devices and web clients, simulating attacks over Message Queuing Telemetry Transport (MQTT) for recording all relevant traffic information. The unsupervised algorithms chosen provide a set (...) of projections that enable human experts to visually identify most attacks in real-time, making it a powerful tool that can be implemented in IoT environments easily.

This paper uses social network analysis to examine the interaction between corporate blogs devoted to sustainability issues and the blogosphere, a clustered online network of collaborative actors. By analyzing the structural embeddedness of a prototypical blog in a virtual community, we show the potential of online platforms to document corporate social responsibility (CSR) activities and to engage with an increasingly socially and ecologically aware stakeholder base. The results of this study show that stakeholder involvement via sustainability blogs is a valuable (...) new practice for CSR communications and stakeholder engagement. It also opens new horizons for communicating CSR issues to key constituencies online. (shrink)

This study explores the relationship between moral intensity and the use of different sensemaking strategies in military critical incidents. First, narratives of military personnel were used to select prototypical high/low moral intensity critical incidents. In a follow-up, a scenario study was conducted with active duty military personnel to examine the relationship between moral intensity and the use of sensemaking tactics. This study offers three main conclusions. First, the use of sensemaking tactics is strongly tied to the level of moral intensity (...) in the situation. In high-intense situations, the servicemen draw on previous experiences, prediction of consequences, and help of others to recognize and interpret the situation. Less attention goes out to higher level critical thinking. Thus, it seems that in these critical incidents, the servicemen react without giving room for thorough consideration and deliberation. Second, the number of deployments a serviceman experienced influences the perceived seriousness and harmfulness of the situation negatively in low-intense situations. Finally, and in line with earlier studies, the results indicate that the concept of moral intensity is formed out of three rather than the six dimensions originally proposed by Jones. The implications of these findings are discussed. (shrink)

Infinite time register machines (ITRMs) are register machines which act on natural numbers and which are allowed to run for arbitrarily many ordinal steps. Successor steps are determined by standard register machine commands. At limit times register contents are defined by appropriate limit operations. In this paper, we examine the ITRMs introduced by the third and fourth author (Koepke and Miller in Logic and Theory of Algorithms LNCS, pp. 306–315, 2008), where a register content at a limit time is set (...) to the lim inf of previous register contents if that limit is finite; otherwise the register is reset to 0. The theory of these machines has several similarities to the infinite time Turing machines (ITTMs) of Hamkins and Lewis. The machines can decide all ${\Pi^1_1}$ sets, yet are strictly weaker than ITTMs. As in the ITTM situation, we introduce a notion of ITRM-clockable ordinals corresponding to the running times of computations. These form a transitive initial segment of the ordinals. Furthermore we prove a Lost Melody theorem: there is a real r such that there is a program P that halts on the empty input for all oracle contents and outputs 1 iff the oracle number is r, but no program can decide for every natural number n whether or not ${n \in r}$ with the empty oracle. In an earlier paper, the third author considered another type of machines where registers were not reset at infinite lim inf’s and he called them infinite time register machines. Because the resetting machines correspond much better to ITTMs we hold that in future the resetting register machines should be called ITRMs. (shrink)

The literature addressing bias and fairness in AI models (fair-AI) is growing at a fast pace, making it difficult for novel researchers and practitioners to have a bird’s-eye view picture of the field. In particular, many policy initiatives, standards, and best practices in fair-AI have been proposed for setting principles, procedures, and knowledge bases to guide and operationalize the management of bias and fairness. The first objective of this paper is to concisely survey the state-of-the-art of fair-AI methods and resources, (...) and the main policies on bias in AI, with the aim of providing such a bird’s-eye guidance for both researchers and practitioners. The second objective of the paper is to contribute to the policy advice and best practices state-of-the-art by leveraging from the results of the NoBIAS research project. We present and discuss a few relevant topics organized around the NoBIAS architecture, which is made up of a Legal Layer, focusing on the European Union context, and a Bias Management Layer, focusing on understanding, mitigating, and accounting for bias.

For the last forty years, two claims have been at the core of disputes about scientific change: that scientists reason rationally and that science is progressive. For most of this time discussions were polarized between philosophers, who defended traditional Enlightenment ideas about rationality and progress, and sociologists, who espoused relativism and constructivism. Recently, creative new ideas going beyond the polarized positions have come from the history of science, feminist criticism of science, psychology of science, and anthropology of science. Addressing the (...) traditional arguments as well as building on these new ideas, Miriam Solomon constructs a new epistemology of science. After discussions of the nature of empirical success and its relation to truth, Solomon offers a new, social account of scientific rationality. She shows that the pursuit of empirical success and truth can be consistent with both dissent and consensus, and that the distinction between dissent and consensus is of little epistemic significance. In building this social epistemology of science, she shows that scientific communities are not merely the locus of distributed expert knowledge and a resource for criticism but also the site of distributed decision making. Throughout, she illustrates her ideas with case studies from late-nineteenth- and twentieth-century physical and life sciences. Replacing the traditional focus on methods and heuristics to be applied by individual scientists, Solomon emphasizes science funding, administration, and policy. One of her goals is to have a positive influence on scientific decision making through practical social recommendations. (shrink)

The question of whether it is ever permissible to believe on insufficient evidence has once again become a live question. Greater attention is now being paid to practical dimensions of belief, namely issues related to epistemic virtue, doxastic responsibility, and voluntarism. In this book, McCormick argues that the standards used to evaluate beliefs are not isolated from other evaluative domains. The ultimate criteria for assessing beliefs are the same as those for assessing action because beliefs and actions are both products (...) of agency. Two important implications of this thesis, both of which deviate from the dominant view in contemporary philosophy, are 1) it can be permissible to believe for non-evidential reasons, and 2) we have a robust control over many of our beliefs, a control sufficient to ground attributions of responsibility for belief.

The aim of this paper is to describe a problem for calibrationism: a view about higher order evidence according to which one's credences should be calibrated to one's expected degree of reliability. Calibrationism is attractive, in part, because it explains our intuitive judgments, and provides a strong motivation for certain theories about higher order evidence and peer disagreement. However, I will argue that calibrationism faces a dilemma: There are two versions of the view one might adopt. The first version, I (...) argue, has the implausible consequence that, in a wide range of cases, calibrationism is the only constraint on rational belief. The second version, in addition to having some puzzling consequences, is unmotivated. At the end of the paper I sketch a possible solution. (shrink)

The aim of this paper is to apply the accuracy based approach to epistemology to the case of higher order evidence: evidence that bears on the rationality of one's beliefs. I proceed in two stages. First, I show that the accuracy based framework that is standardly used to motivate rational requirements supports steadfastness—a position according to which higher order evidence should have no impact on one's doxastic attitudes towards first order propositions. The argument for this will require a generalization of (...) an important result by Greaves and Wallace for the claim that conditionalization maximizes expected accuracy. The generalization I provide will, among other things, allow us to apply the result to cases of self-locating evidence. In the second stage, I develop an alternative framework. Very roughly, what distinguishes the traditional approach from the alternative one is that, on the traditional picture, we're interested in evaluating the expected accuracy of conforming to an update procedure. On the alternative picture that I develop, instead of considering how good an update procedure is as a plan to conform to, we consider how good it is as a plan to make. I show how, given the use of strictly proper scoring rules, the alternative picture vindicates calibrationism: a view according to which higher order evidence should have a significant impact on our beliefs. I conclude with some thoughts about why higher order evidence poses a serious challenge for standard ways of thinking about rationality. (shrink)

This paper takes a new look at an old question: what is the human self? It offers a proposal for theorizing the self from an enactive perspective as an autonomous system that is constituted through interpersonal relations. It addresses a prevalent issue in the philosophy of cognitive science: the body-social problem. Embodied and social approaches to cognitive identity are in mutual tension. On the one hand, embodied cognitive science risks a new form of methodological individualism, implying a dichotomy not between (...) the outside world of objects and the brain-bound individual but rather between body-bound individuals and the outside social world. On the other hand, approaches that emphasize the constitutive relevance of social interaction processes for cognitive identity run the risk of losing the individual in the interaction dynamics and of downplaying the role of embodiment. This paper adopts a middle way and outlines an enactive approach to individuation that is neither individualistic nor disembodied but integrates both approaches. Elaborating on Jonas’ notion of needful freedom it outlines an enactive proposal to understanding the self as co-generated in interactions and relations with others. I argue that the human self is a social existence that is organized in terms of a back and forth between social distinction and participation processes. On this view, the body, rather than being identical with the social self, becomes its mediator. (shrink)

Had we grown up elsewhere or been educated differently, our view of the world would likely be radically different. What to make of this? This paper takes an accuracy-centered first-personal approach to the question of how to respond to the arbitrary nature in which many of our beliefs are formed. I show how considerations of accuracy motivate different responses to this sort of information depending on the type of attitude we take towards the belief in question upon subjecting the belief (...) to doubt.

How is medical knowledge made?

REVIEW ESSAY The minimal self needs a social update Self and other: Exploring subjectivity, empathy, and shame, by Dan Zahavi, Oxford, Oxford University Press, 2015, 304 pp.

The concept of a “validator” as a unit of evidence for the validity of a psychiatric category has been important for more than fifty years. Validator evidence is aggregated by expert committees (for the Diagnostic and Statistical Manual of Mental Disorders (DSM), these are referred to as “workgroups”), which use the results to make nosological decisions. Through an examination of the recent history of psychiatric research, this paper argues that it is time to reassess this traditional practice. It concludes with (...) specific suggestions for going forward. (shrink)

In this paper, I begin by defending permissivism: the claim that, sometimes, there is more than one way to rationally respond to a given body of evidence. Then I argue that, if we accept permissivism, certain worries that arise as a result of learning that our beliefs were caused by the communities we grew up in, the schools we went to, or other irrelevant influences dissipate. The basic strategy is as follows: First, I try to pinpoint what makes irrelevant influences (...) worrying and I come up with two candidate principles. I then argue that one principle should be rejected because it is inconsistent with permissivism. The principle we should accept implies that it is sometimes rational to maintain our beliefs, even upon learning that they were caused by irrelevant influences. (shrink)

After the discovery of the anthropoid ape in Asia and in Africa, eighteenth-century Holland became the crossroads of Enlightenment debates about the human species. Material evidence about human diversity reached Petrus Camper, comparative anatomist in the Netherlands, who engaged, among many other interests, in menschkunde. Could only religious doctrine support the belief of human demarcation from animals? Camper resolved the challenges raised by overseas discoveries with his thesis of the facial angle, a theory which succeeding generations distorted and misused in (...) order to justify slavery, racism, antisemitism, and genocide. Thanks to his abundant papers in Dutch archives, Camper's ideas are restored to their original state. Eighteenth-century issues differed from those of other centuries: Did orang-utans talk like humans, walk like humans; even rape humans? What was the skin pigmentation of Adam and Eve? Did the spectrum of human physiognomies around the globe reflect the Fall of Man, the Creator's bounty, or merely bizarre beauty practices? Why did the ideal beauty of the Greeks appear to be the reverse of the Hottentots? The book contains some 50 illustrations, including apes with hiking sticks or tea cups, metamorphoses of living forms, and Apollo or Venus icons which titillated the science of man. (shrink)

This paper is about the connection between rationality and accuracy. I show that one natural picture about how rationality and accuracy are connected emerges if we assume that rational agents are rationally omniscient. I then develop an alternative picture that allows us to relax this assumption, in order to accommodate certain views about higher order evidence.

Greaves and Wallace argue that conditionalization maximizes expected accuracy. In this paper I show that their result only applies to a restricted range of cases. I then show that the update procedure that maximizes expected accuracy in general is one in which, upon learning P, we conditionalize, not on P, but on the proposition that we learned P. After proving this result, I provide further generalizations and show that much of the accuracy-first epistemology program is committed to KK-like iteration principles (...) and to the existence of a class of propositions that rational agents will be certain of if and only if they are true.

The article deals with larger stretches of talk-in-interaction and argues in favor of a descriptive approach, which integrates the structural requirements of global organization, the special type of sequential orderliness within larger units as well as the genre-orientation of these units. Drawing on previous work in conversation analysis, discourse analysis and the sociological genre analysis, the article introduces GLOBE as an analytical tool which functionally links discourse units to conventionalized communicative purposes. GLOBE reconstructs the interactive achievement of genre-oriented discourse units (...) in a three-branch analysis of jobs, devices and forms. The analytical potential of GLOBE is demonstrated in the exemplary genre-contrastive analysis of a narrative, an explanative and an argumentative excerpt. On the basis of the analyses of the three genres, the overarching constitution of genre-oriented global units is then explicated. (shrink)

Non-financial interests, and the conflicts of interest that may result from them, are frequently overlooked in biomedicine. This is partly due to the complex and varied nature of these interests, and the limited evidence available regarding their prevalence and impact on biomedical research and clinical practice. We suggest that there are no meaningful conceptual distinctions, and few practical differences, between financial and non-financial conflicts of interest, and accordingly, that both require careful consideration. Further, a better understanding of the complexities of (...) non-financial conflicts of interest, and their entanglement with financial conflicts of interest, may assist in the development of a more sophisticated approach to all forms of conflicts of interest.

In recent years, permissivism—the claim that a body of evidence can rationalize more than one response—has enjoyed somewhat of a revival. But it is once again being threatened, this time by a host of new and interesting arguments that, at their core, are challenging the permissivist to explain why rationality matters. A version of the challenge that I am especially interested in is this: if permissivism is true, why should we expect the rational credences to be more accurate than the (...) irrational ones? My aim is to turn this challenge on its head and argue that, actually, those who deny permissivism will have a harder time responding to such a challenge than those who accept it. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Feminist Studies 45, no. 1. © 2019 by Feminist Studies, Inc. 129 Miriam Kienle Dear Data: Feminist Information Design’s Resistance to Self-Quantification Every Sunday for one year, information designers Giorgia Lupi and Stefanie Posavec sent each other a hand-drawn postcard that featured a data visualization of their week as it pertained to a single aspect of their daily lives: doors opened, clocks checks, sounds heard, smells perceived, and (...) so on (figs. 1–4). With this series of postcards exchanged between Brooklyn and London, Lupi and Posavec gained intimate knowledge of one another through their small/slow data, and at the same time, they produced a critical examination of the capture, interpretation, and visualization of their daily data from a uniquely feminist perspective. Although the field of information design prizes clear, efficient, and seamless presentations of quantified activity, Lupi and Posavec’s Dear Data (2015) is comprised of visualizations that underscore complexity over clarity, present questions rather simply display information, and expose the instability of data itself.1 Against the quantification of embodied experience into seemingly objective and all-encompassing datasets, Dear Data instead looks at data from a feminist perspective, as tied to concrete bodies, localities, and temporalities and visualized in a manner 1. The approach to infographics that prioritizes efficiency, accuracy, and elegance, and thus suppresses the constructed and interpretative nature of both data and its visualization, is perhaps most attributed to Edward Tufte. For Tufte’s aims and methods, see Edward R. Tufte, The Visual Display of Quantitative Information (Cheshire, CT: Graphics Press, 2001). 130 Miriam Kienle that is incomplete, contingent, and constructed.2 This paper will analyze Lupi and Posavec’s designs as providing a model for a feminist approach to data visualization—a model imperative in an age in which the quantitative information (much like a binary understanding of gender) is too often treated as a self-evident fact rather than what feminist philosopher Donna Haraway famously called “situated knowledges.”3 Recently acquired by MoMA’s architecture and design collection, the Dear Data project not only stands out in the collection as the product of two female designers working in the male-dominated fields of technology and design, but also as a project that stresses feminist knowledge production by underscoring how data voids shape datasets and debunking the myth that the world is data that can be captured and visualized with neutral, distanced, and all-encompassing technologies of vision. As Catherine D’Ignazio and Lauren Klein describe in Data Feminism, data visualization from a feminist perspective understands that “bar charts might seem neutral and objective, but are in fact the result of very human and necessarily imperfect design processes.”4 Such a perspective is evident across Dear Data. Take, for example, “Week 42: A week of laughter” (fig. 5). On the key in Posavec’s visualization, she notes: “I tried to capture my laughs which was really hard + got in the way of the enjoying life, hence the data voids. / For a card about laughter I am sad about how this card turned out.”5 This willingness to show the gaps in her data, the complexities of her process, and the imperfections of her visualizations contrasts with the seamless and straightforward displays of information 2.

This paper looks to phenomenology and enactive cognition in order to shed light on the self and sense of self of patients with locked-in syndrome. It critically discusses the concept of the minimal self, both in its phenomenological and ontological dimension. Ontologically speaking, the self is considered to be equal to a person’s sensorimotor embodiment. This bodily self also grounds the minimal sense of self as being a distinct experiential subject. The view from the minimal bodily self presupposes that sociality (...) comes after the self, or that in other words, the essence of self remains independent of our social interactions and relations. In this paper, I rely on the idea of enactive autonomy and Heidegger’s and Merleau-Ponty’s views of human existence as primordially social, to argue for the contrary. The self is fundamentally relational and this is also reflected at the level of the subjective experience of being a self. I indicate how a strong relational view of selfhood can serve as a preliminary heuristic to make sense of the situation of the patient with LIS and conclude with some practical implications concerning patient autonomy, our ethical responsibility toward the patient, and the possibilities for improving the life of patients with LIS.

My main aim in this paper is to specify conditions that distinguish rational, or justified, hope from irrational, or unjustified hope. I begin by giving a brief characterization of hope and then turn to offering some criteria of rational hope. On my view both theoretical and practical norms are significant when assessing hope’s rationality. While others have recognized that there are theoretical and practical components to the state itself, when it comes to assessing its rationality, depending on the account, only (...) one of these dimensions matters. Either hope’s rationality is taken to be entirely derivative on the rationality of some belief that the hope entails, or the focus is entirely on the practical dimensions. If we take seriously the idea that both kinds of norms are at play, an account which treats these both as salient and as intertwining in important ways is preferable. I argue that as the practical importance of hope increases, the demand for the level of evidential support lessens and as the stakes get lower, the evidence for the likeliness of the hoped-for outcome coming to be must go up for the hope to be rational. This is so because a hope is rational insofar as it contributes to agential flourishing, but the different dimensions of hope each pick out different aspects of agency; to hope well requires agential competence in both the epistemic and practical realms.

It has been claimed that, in response to certain kinds of evidence, agents ought to adopt imprecise credences: doxastic states that are represented by sets of credence functions rather than single ones. In this paper I argue that, given some plausible constraints on accuracy measures, accuracy-centered epistemologists must reject the requirement to adopt imprecise credences. I then show that even the claim that imprecise credences are permitted is problematic for accuracy-centered epistemology. It follows that if imprecise credal states are permitted (...) or required in the cases that their defenders appeal to, then the requirements of rationality can outstrip what would be warranted by an interest in accuracy.

Abstract: This paper defends a constraint that any satisfactory decision theory must satisfy. I show how this constraint is violated by all of the decision theories that have been endorsed in the literature that are designed to deal with cases in which opinions or values are represented by a set of functions rather than a single one. Such a decision theory is necessary to account for the existence of what Ruth Chang has called “parity” (as well as for cases in (...) which agents have incomplete preferences or imprecise credences). The problem with the all of the decision theories that have been defended to account for parity is that they are committed to a claim I call unanimity: when all of the functions in the set agree that an agent ought to do A, then an agent ought to do A. A decision theory committed to unanimity violates the constraint I defend in this paper. Thus, if parity exists, a new approach to decision theory is necessary. (shrink)

It seems like we care about at least two features of our credence function: gradational-accuracy and verisimilitude. Accuracy-first epistemology requires that we care about one feature of our credence function: gradational-accuracy. So if you want to be a verisimilitude-valuing accuracy-firster, you must be able to think of the value of verisimilitude as somehow built into the value of gradational-accuracy. Can this be done? In a recent article, Oddie has argued that it cannot, at least if we want the accuracy measure (...) to be proper.

My main aim is to argue that most conceptions of doxastic agency do not respond to the skeptic’s challenge. I begin by considering some reasons for thinking that we are not doxastic agents. I then turn to a discussion of those who try to make sense of doxastic agency by appeal to belief’s reasons-responsive nature. What they end up calling agency is not robust enough to satisfy the challenge posed by the skeptics. To satisfy the skeptic, one needs to make (...) sense of the possibility of believing for nonevidential reasons. While this has been seen as an untenable view for both skeptics and anti-skeptics, I conclude by suggesting it is a position that has been too hastily dismissed. (shrink)

This article explores how ‘biology’ — in the sense that bodies are increasingly understood in biological terms, from the molecular to the species level — is becoming more central in the recognition of political worth, and I argue that humanitarians are key players in producing this reality. I focus on the role biology plays in the politics of immigration. Combining ethnographic research with undocumented immigrants in Paris and asylum claimants in the US, I examine how biology has become a central (...) tool in the ability to travel. How did pathology (i.e. illness) or violations of anatomy (i.e. torture, sexual violence) become the ‘best’ ways to get papers as an undocumented immigrant — better than selling one’s labor power? I suggest that biological evidence — of illness, of torture, of immunity levels — are used as key measurements of suffering, which justifies humanitarian exceptions, in this case, for papers. My argument is that there is a dual regime of truth at work, where the multiple ontologies of biology get reduced to one epistemology of biology as ‘fixed’ when it concerns immigrants and refugees, due to the role of humanitarianism in the politics of immigration. This is explored in the context of profound inequalities between those in the global North and South, asking how the hope offered by biological evidence takes on different meanings and consequences depending on one’s position in the global matrix of wealth and poverty, race and gender.
