The ability to quickly and accurately recognise emotional states is adaptive for numerous social functions. Although body movements are a potentially crucial cue for inferring emotions, few studies have studied the perception of body movements made in naturalistic emotional states. The current research focuses on the use of body movement information in the perception of fear expressed by targets in a virtual heights paradigm. Across three studies, participants made judgments about the emotional states of others based on motion-capture body movement (...) recordings of those individuals actively engaged in walking a virtual plank at ground-level or 80 stories above a city street. Results indicated that participants were reliably able to differentiate between height and non-height conditions (Studies 1 & 2), were more likely to spontaneously describe target behaviour in the height condition as fearful (Study 2) and their fear estimates were highly calibrated with the fear ratings from the targets (Studies 1-3). Findings show that VR height scenarios can induce fearful behaviour and that people can perceive fear in minimal representations of body movement. (shrink)

The Bayesian maxim for rational learning could be described as conservative change from one probabilistic belief or credence function to another in response to newinformation. Roughly: ‘Hold fixed any credences that are not directly affected by the learning experience.’ This is precisely articulated for the case when we learn that some proposition that we had previously entertained is indeed true (the rule of conditionalisation). But can this conservative-change maxim be extended to revising one’s credences in response to entertaining propositions or (...) concepts of which one was previously unaware? The economists Karni and Vierø (2013, 2015) make a proposal in this spirit. Philosophers have adopted effectively the same rule: revision in response to growing awareness should not affect the relative probabilities of propositions in one’s ‘old’ epistemic state. The rule is compelling, but only under the assumptions that its advocates introduce. It is not a general requirement of rationality, or so we argue. We provide informal counterexamples. And we show that, when awareness grows, the boundary between one’s ‘old’ and ‘new’ epistemic commitments is blurred. Accordingly, there is no general notion of conservative change in this setting.

The ecosystem services argument is a highly publicised instrumental argument for protecting biodiversity. I develop a new objection to this argument based on the lack of a causal connection from global species losses to local ecosystem changes. I survey some alternative formulations of services arguments, including ones incorporating option value or a precautionary principle, and show that they do not fare much better than the standard version. I conclude that environmental thinkers should rely less on ecosystem services as a means (...) to defend biodiversity, and that attention should be focused on additional types of value which might be attributed to global biodiversity.

Although statistically common, and legal since 1973, abortion still bears significant stigma--a proverbial scarlet A. Fear of this stigma leads most of the women and men who are part of the 21% of American pregnancies that end in abortion to remain silent. This book brings the story of ordinary abortion out of the shadows and invites a new conversation about its actual practice, ethics, politics, and law. Katie Watson lends her incisive legal and medical ethics expertise to navigate wisely (...) and respectfully one of the most divisive topics of contemporary life. (shrink)

This article is about the special, subjective concepts we apply to experience, called “phenomenal concepts”. They are of special interest in a number of ways. First, they refer to phenomenal experiences, and the qualitative character of those experiences whose metaphysical status is hotly debated. Conscious experience strike many philosophers as philosophically problematic and difficult to accommodate within a physicalistic metaphysics. Second, PCs are widely thought to be special and unique among concepts. The sense that there is something special about PCs (...) is very closely tied up with features of the epistemic access they afford to qualia. When we deploy phenomenal concepts introspectively to some phenomenally conscious experience as it occurs, we are said to be acquainted with our own conscious experiences. Accounts of PCs either have to explain the acquaintance relation, or acquaintance with our phenomenal experiences has to be denied. PCs have received much attention in recent philosophy of mind mainly because they figure in arguments for dualism and in physicalist responses to these arguments. The main topic of this paper is to explore different accounts of phenomenal concepts and their role in recent debates over the metaphysical status of phenomenal consciousness. (shrink)

I develop an account of ecological role functions—the functions of species within ecosystems—which is informed by alternative regime phenomena in ecology. My account is a causal-role theory which includes a counterfactual sensitivity condition. The account tracks and explains a distinction ecologists make between functions and various activities which are not functions. My counterfactual sensitivity condition resolves the liberality problem often attributed to causal-role theories of function, while also illuminating the explanatory centrality of role functions within ecology.

Over the years, Katie Cannon's students referred to her work in progress as "Katie's canon." Not only does this book represent the canon of Cannon's best work; the book itself directly addresses the issues of canon formation and canon reformation. Cannon canonizes a literary tradition and directly addresses both oppression and liberation of African American women. Now in an expanded 25th-anniversary edition, Katie's Canon still packs firepower.

While the fundamental laws of physics are time-reversal invariant, most macroscopic processes are irreversible. Given that the fundamental laws are taken to underpin all other processes, how can the fundamental time-symmetry be reconciled with the asymmetry manifest elsewhere? In statistical mechanics, progress can be made with this question. What I dub the ‘Zwanzig–Zeh–Wallace framework’ can be used to construct the irreversible equations of SM from the underlying microdynamics. Yet this framework uses coarse-graining, a procedure that has faced much criticism. I (...) focus on two objections in the literature: claims that coarse-graining makes time-asymmetry ‘illusory’ and ‘anthropocentric’. I argue that these objections arise from an unsatisfactory justification of coarse-graining prevalent in the literature, rather than from coarse-graining itself. This justification relies on the idea of measurement imprecision. By considering the role that abstraction and autonomy play, I provide an alternative justification and offer replies to the illusory and anthropocentric objections. Finally, I consider the broader consequences of this alternative justification: the connection to debates about inter-theoretic reduction and the implication that the time-asymmetry in SM is weakly emergent. 1Introduction 1.1Prospectus2The Zwanzig–Zeh–Wallace Framework3Why Does This Method Work? 3.1The special conditions account3.2When is a density forwards-compatible?4Anthropocentrism and Illusion: Two Objections 4.1The two objections in more detail4.2Against the justification by measurement imprecision5An Alternative Justification 5.1Abstraction and autonomy5.2An illustration: the Game of Life6Reply to Illusory7Reply to Anthropocentric8The Wider Landscape: Concluding Remarks 8.1Inter-theoretic relations8.2The nature of irreversibility.

This study identified and described ethical problems encountered by physiotherapists in their practice and physiotherapists’ moral sensitivity in ethical situations. A questionnaire-based survey was constructed to identify ethical problems, and the Moral Sensitivity Questionnaire Revised version was used to measure moral sensitivity. Physiotherapists (n = 116) working in public health services responded to the questionnaire. Based on the results, most of the physiotherapists encounter ethical problems weekly. They concern mainly financial considerations, equality and justice, professionalism, unethical conduct of physiotherapists or (...) other professions and patients’ self-determination. The dimension of moral strength was emphasised in physiotherapists’ self-evaluations of their moral sensitivity. As a conclusion, ethical problems do occur not only at individual level but also at organisational and society level. Physiotherapists seem to have moral strength for speaking on behalf of the patient. Scarce resources make them feel insufficient but much could still be done to provide quality care in co-operation with other health-care professionals. (shrink)

This paper addresses the stalemate on the question whether biodiversity has intrinsic value. I distinguish between a “weak” conception and two “strong” conceptions of intrinsic value in the environmental ethics literature. The strong conceptions of intrinsic value are connected, respectively, to moral standing and to a strongly objectivist account of value. Neither of these forms of value likely applies to biodiversity. However, the weak conception of intrinsic value is neutral about both moral standing and the nature of value and plausibly (...) applies to biodiversity. In addition, weak intrinsic value avoids common objections to the claim that biodiversity is intrinsically valuable. I develop a cumulative argument showing that environmentalists should presume that biodiversity has intrinsic value in the weak sense. (shrink)

The search for the statistical mechanical underpinning of thermodynamic irreversibility has so far focussed on the spontaneous approach to equilibrium. But this is the search for the underpinning of what Brown and Uffink have dubbed the ‘minus first law’ of thermodynamics. In contrast, the second law tells us that certain interventions on equilibrium states render the initial state ‘irrecoverable’. In this article, I discuss the unusual nature of processes in thermodynamics, and the type of irreversibility that the second law embodies. (...) I then search for the microscopic underpinning or statistical mechanical ‘reductive basis’ of the second law of thermodynamics by taking a functionalist strategy. First, I outline the functional role of the thermodynamic entropy: for a thermally isolated system, the thermodynamic entropy is constant in quasi-static processes, but increasing in non-quasi-static processes. I then search for the statistical mechanical quantity that plays this role—rather than the role of the traditional ‘holy grail’ as described by Callender. I argue that in statistical mechanics, the Gibbs entropy plays this role. (shrink)

Theories of emotion have often maintained artificial boundaries: for instance, that cognition and emotion are separable, and that an emotion concept is separable from the emotional events that comprise its category (e.g. “fear” is distinct from instances of fear). Over the past several years, research has dissolved these artificial boundaries, suggesting instead that conceptual construction is a domain-general process—a process by which the brain makes meaning of the world. The brain constructs emotion concepts, but also cognitions and perceptions, all in (...) the service of guiding action. In this view, concepts are multimodal constructions, dynamically prepared from a set of highly variable instances. This approach obviates old questions (e.g. how does cognition regulate emotion?) but generates new ones (e.g. how does a brain learn emotion concepts?). In this paper, we review this constructionist, predictive coding account of emotion, considering its implications for health and well-being, culture and development. (shrink)

This article examines the use of cinematic microanalysis to capture, decompose, and interpret mother–infant interaction in the decades following the Second World War. Focusing on the films and writings of Margaret Mead, Ray Birdwhistell, René Spitz, and Sylvia Brody, it examines the intellectual culture, and visual methodologies, that transformed ‘pathogenic’ mothering into an observable process. In turn, it argues that the significance assigned to the ‘small behaviours’ of mothers provided an epistemological foundation for the nascent discipline of infant psychiatry. This (...) research draws attention to two new areas of enquiry within the history of emotions and the history of psychiatry in the post-war period: preoccupation with emotional absence and affectlessness, and their personal and cultural meanings; and the empirical search for the origin point, and early chronology, of mental illness.

Ecological neutral theory has been controversial as an alternative to niche theory for explaining community structure. Neutral theory, which explains community structure in terms of ecological drift, is frequently charged with being unrealistic, but commentators have usually not provided an account of theory or model realism. In this paper, I propose a framework for comparing the “realism” or accuracy of alternative theories within a domain with respect to the extent to which the theories abstract and idealize. Using this framework I (...) argue, contrary to most previous commentators, that neutral and niche theories are similarly realistic. Realism cannot provide a basis for accepting or rejecting either type of theory; instead, community ecologists should continue working with a plurality of models. While theoretical unification may become possible, we should treat a plurality of complementary, partial models as the expected situation within community ecology. (shrink)

Internet protocol development is a social process, and resulting protocols are shaped by their developers’ politics and values. This article argues that the work of protocol development poses barriers to developers’ reflection upon values and politics in protocol design. A participant observation of a team developing internet protocols revealed that difficulties defining the stakeholders in an infrastructure and tensions between local and global viewpoints both complicated values reflection. Further, Internet architects tended to equate a core value of interoperability with values (...) neutrality. The article describes how particular work practices within infrastructure development overcame these challenges by engaging developers in praxis: situated, lived experience of the social nature of technology.

This article draws on the ethnography of Aboriginal Australia to argue that perceptual openness, extending from waking life into dreaming experience, provides an important cognitive framework for the apprehension of dreamt experience in these contexts. I argue that this perceptual openness is analogous to the “openness to experience” described as a personality trait that had been linked with dream recall frequency. An implication of identifying perceptual openness at a cultural rather than at an individual level is two-fold. It provides an (...) example of the ways in which cultural differences affect perception, indicative of cognitive diversity; and, given the relationship between dreams and creativity suggested anecdotally and through research, a cultural orientation toward perceptual openness is also likely to have implications for the realization of creativity that occurs through dreams. Such creativity though cannot be separated from the relational context in which such dreamt material is elaborated and understood. (shrink)

On the 24th June 2015, Feminist Legal Studies and the London School of Economics Law Department hosted an afternoon event with Professor Wendy Brown, Class of 1936 First Professor of Political Science, University of California. Professor Brown kindly agreed to discuss her scholarship on feminist theory, and its relationship to both the law and neoliberalism. The event included an interview by Dr Katie Cruz and a Q&A session, which are presented here in an edited version of the transcript. Sumi (...) Madhock, Professor of Gender Studies, LSE chaired the interview and discussion and introduced Professor Brown’s work. Katie Cruz asked Wendy Brown to reflect upon topics that span her scholarship and activism, including the state of critical, feminist, and Left approaches to rights, neoliberalism, despair and utopianism, and the future of feminist theory and practice in the context of neoliberalism and current debates about intersectionality. Participants in the discussion asked questions on a wide range of issues, including the limits of feminist engagement with law as a tool for social change, the dominance of neoliberalism, imperialist feminism, Islamophobia, secularism, and our attachment to the figure of homo politicus.

Recent critics (Andrew Light, Bryan Norton, Anthony Weston, and Bruce Morito, among others) have argued that we should give up talk of intrinsic value in general and that of nature in particular. While earlier theorists might have overestimated the importance of intrinsic value, these recent critics underestimate its importance. Claims about a thing’s intrinsic value are claims about the distinctive way in which we have reason to care about that thing. If we understand intrinsic value in this manner, we can (...) capture the core claims that environmentalists want to make about nature while avoiding the worries raised by contemporary critics. Since the distinction between intrinsic and extrinsic value plays a critical role in our understanding of the different ways that we do and should care about things, moral psychology, ethical theory in general, and environmental ethics in particular shouldn’t give up on the concept of intrinsic value.

When once-successful physical theories are abandoned, common wisdom has it that their characteristic theoretical entities are abandoned with them: examples include phlogiston, light rays, Newtonian forces, Euclidean space. But sometimes a theory sees ongoing use, despite being superseded. What should scientific realists say about the characteristic entities of the theories in such cases? The standard answer is that these ‘theoretical relicts’ are merely useful fictions. In this paper we offer a different answer. We start by distinguishing horizontal reduction (in which (...) a superseded theory approximates the successor theory) from vertical reduction (in which a higher-level theory abstracts away from the lower-level theory, but nonetheless can be constructed from it); these are usually regarded as having different ontological consequences. We describe a ‘verticalization’ procedure which transforms horizontal reductions into vertical reductions. The resulting verticalized theories are abstractions rather than approximations, with restricted domains. We identify a sense in which the higher-level theory describes distinct subject matters from the lower-level theory, enabling in certain cases the higher-level theory to retain distinctive explanatory power even in the presence of reduction. We suggest that theoretical entities from superseded theories should be retained in a scientific realist worldview just when, reinterpreted as higher-level abstractions, those theories and their characteristic entities continue to perform distinctive explanatory work in providing the best explanation for less-fundamental phenomena of interest. In slogan form: a good relict is an emergent relict. (shrink)

In this note we show that the classical modal technology of Sahlqvist formulas gives quick proofs of the completeness theorems in [8] (D. Gregory, Completeness and decidability results for some propositional modal logics containing “actually” operators, Journal of Philosophical Logic 30(1): 57–78, 2001) and vastly generalizes them. Moreover, as a corollary, interpolation theorems for the logics considered in [8] are obtained. We then compare Gregory's modal language enriched with an “actually” operator with the work of Arthur Prior now known under (...) the name of hybrid logic. This analysis relates the “actually” axioms to standard hybrid axioms, yields the decidability results in [8], and provides a number of complexity results. Finally, we use a bisimulation argument to show that the hybrid language is strictly more expressive than Gregory's language. (shrink)

The WHO recently made news by apparently advising couples in Zika affected areas to delay pregnancy. On closer inspection, however, it is not so clear what advice was actually being offered in their interim guidance regarding the prevention of the sexual transmission of Zika. In this paper, we lay out a framework for considering the ethical issues that arise in the context of advising and use it to evaluate the WHO guidance. We argue that advising is not merely an informative (...) act. The choices that agencies make in how and whom they advise are ethical choices with practical implications; these choices change not only how people ought to think about their options but also how they indeed ought to act. While we focus on these interim guidance updates from the WHO, the framework we provide can shed light more generally on the ethical issues surrounding advising in other public health contexts.

In what sense are the special sciences autonomous of fundamental physics? Autonomy is an enduring theme in discussions of the relationship between the special sciences and fundamental physics or, more generally, between higher and lower-level facts. Discussion of ‘autonomy’ often fails to recognise that autonomy admits of degrees; consequently, autonomy is either taken to require full independence, or risk relegation to mere apparent autonomy. In addition, the definition of autonomy used by Fodor, the most famous proponent of the autonomy of (...) the special sciences, has been robustly criticised by Loewer. In this paper I develop a new account of autonomy following Woodward which I dub ‘generalised autonomy’ since it unifies dynamical, causal and nomic autonomy. Autonomy, on this account, can be partial: some lower-level details matter while others do not. To summarise: whilst the detailed lower level is unconditionally relevant, conditionalising on the higher-level facts renders some lower-level details irrelevant. The macrodependencies that the higher-level facts enter into — be they dynamical, causal or nomic — screen off the underlying microdetails. This account helps resolve an explanatory puzzle: if the lower-level facts in some way underpin the higher-level facts, why don’t the lower-level details matter more for the day-to-day practice of the special sciences? The answer will be: the facts uncovered by the special sciences are autonomous in my sense, and so practitioners of these special sciences need not study more fundamental sciences, since these underlying facts are genuinely irrelevant.

There is growing consensus that teaching computer ethics is important, but there is little consensus on how to do so. One unmet challenge is increasing the capacity of computing students to make decisions about the ethical challenges embedded in their technical work. This paper reports on the design, testing, and evaluation of an educational simulation to meet this challenge. The privacy by design simulation enables more relevant and effective computer ethics education by letting students experience and make decisions about common (...) ethical challenges encountered in real-world work environments. This paper describes the process of incorporating empirical observations of ethical questions in computing into an online simulation and an in-person board game. We employed theValues at Playframework to transform empirical observations of design into a playable educational experience. First, we conducted qualitative research to discover when and how values levers—practices that encourage values discussions during technology development—occur during the design of new mobile applications. We then translated these findings into gameplay elements, including the goals, roles, and elements of surprise incorporated into a simulation. We ran the online simulation in five undergraduate computer and information science classes. Based on this experience, we created a more accessible board game, which we tested in two undergraduate classes and two professional workshops. We evaluated the effectiveness of both the online simulation and the board game using two methods: a pre/post-test of moral sensitivity based on the Defining Issues Test, and a questionnaire evaluating student experience. We found that converting real-world ethical challenges into a playable simulation increased student’s reported interest in ethical issues in technology, and that students identified the role-playing activity as relevant to their technical coursework. This demonstrates that roleplaying can emphasize ethical decision-making as a relevant component of technical work. (shrink)

The niche has been central to ecology for most of the discipline’s history, yet there have been few attempts by philosophers to work out the ontology of the niche. A challenge is that there is a plurality of seemingly inconsistent definitions of the niche in ecology. This paper characterizes the population-level ecological niche by distinguishing among niche concepts, niche models, and the niche as a phenomenon. I argue that 'niche concepts' should be interpreted as theoretical frameworks or modelling strategies. I (...) also argue that there is a unified niche phenomenon underlying the seemingly heterogeneous models and definitions. The plurality of niche concepts in ecology should be seen as an expected consequence of the nature of modelling complex systems. (shrink)

In this paper we describe the impact that Walton’s conception of argumentation schemes had on AI and Law research. We will discuss developments in argumentation in AI and Law before Walton’s schemes became known in that community, and the issues that were current in that work. We will then show how Walton’s schemes provided a means of addressing all of those issues, and so supplied a unifying perspective from which to view argumentation in AI and Law.

In this paper we describe an approach to practical reasoning, reasoning about what it is best for a particular agent to do in a given situation, based on presumptive justifications of action through the instantiation of an argument scheme, which is then subject to examination through a series of critical questions. We identify three particular aspects of practical reasoning which distinguish it from theoretical reasoning. We next provide an argument scheme and an associated set of critical questions which is able (...) to capture these features. In order that both the argument scheme and the critical questions can be given precise interpretations we use the semantic structure of an Action-Based Alternating Transition System as the basis for their definition. We then work through a detailed example to show how this approach to practical reasoning can be applied to a problem solving situation, and briefly describe some other previous applications of the general approach. In a second example we relate our account to the social laws paradigm for co-ordinating multi-agent systems. The contribution of the paper is to provide firm foundations for an approach to practical reasoning based on presumptive argument in terms of a well-known model for representing the effects of actions of a group of agents.

This article explores the experiences of Latina lesbian migrants living in the United States. Drawing on in-depth interviews with 15 Latina lesbian migrants, I argue that Latinas' sexual, racial, and class identities are continuously shifting as the process of migration repositions them in a new system of racial inequality. Their sexual identities are altered as migrants often silence their lesbian existence when negotiating relationships with families of origin. Lesbianas establish borderland spaces for themselves where they gain sexual autonomy but where (...) their identities are in flux. These spaces are “imagined communities” because while lesbianas envision them to provide solidarity, in practice the borderlands are riddled with inequalities and tensions. Despite this, the borderlands allow lesbianas to develop a mestiza consciousness. (shrink)
