Intrinsic gait variability, i.e., fluctuations in the regularity of gait patterns between repetitive cycles, is inherent to the sensorimotor system and influenced by factors such as age and pathology. Increased GV is associated with gait impairments in individuals with cerebral palsy and has been mainly studied based on spatiotemporal parameters. The present study aimed to describe kinematic GV in young people with CP and its associations with clinical impairments [i.e., passive range of motion, muscle weakness, reduced selective motor control, and (...) spasticity]. This retrospective study included 177 participants with CP representing 289 clinical gait analyses [n = 172 for unilateral CP vs. 117 for bilateral CP ]. As variability metrics, Root Mean Square Deviation for nine lower-limb kinematic parameters and Gait Standard Deviation – as composite score of the kinematic parameters – were computed for the affected and most affected side, respectively, as defined by clinical scores. GaitSD was then computed for the non/less-affected side for between leg comparisons. Uni- and multivariate linear regressions were subsequently performed on GaitSD of the affected/most affected side with all clinical impairments as independent variables. Highest RMSD were found in the transverse plane, for distal joints in the sagittal plane and for foot progression. GaitSD was not different between uCP and bCP but higher in the non-affected vs. affected side in uCP. GaitSD was associated with age, gait deviation index, muscle weakness, selectivity, and pROM. After adjustment for age and GDI, GaitSD remained associated with muscle weakness and selectivity. Kinematic GV can be expressed as global indicator of variability in young people with CP given the strong correlation of RMSD for lower-limb kinematic parameters. In terms of asymmetry, increased variability of the non-affected vs. affected side may indicate contralateral compensation mechanisms in uCP. Notably muscle weakness and selectivity – but not spasticity – were associated with GaitSD. Further studies need to explore the clinical relevance of kinematic GV in CP to support the interpretation of clinical gait analyses and therapeutic decision-making. (shrink)

Against recent work by Haslanger and Leslie, I argue that we do not yet have good reason to think that we should single out generics about social groups out as peculiarly destructive, or that we should strive to eradicate them from our usage. Indeed, I suggest they continue to serve a very valuable purpose and we should not rush to condemn them.

Philosophers of language have tended to focus on examples that are not politically significant in any way. We spend a lot of time analyzing natural kind terms: We think hard about “water” and “pain” and “arthritis.” But we don’t think much about the far more politically significant kind terms (natural or social—it's a matter for dispute) like “race,” “sex,” “gender,” “woman,” “man,” “gay,” and “straight.” In this essay, I will try to show, using the example of “woman,” that it's worth (...) thinking about terms like these, for at least three reasons: (1) There are some interesting puzzles. (2) Politically significant terms matter to people's lives— and it's worth spending at least some of our energy thinking about things that matter in this way. (3) Most importantly, interesting methodological issues emerge at the intersection of philosophy of language and politics. (shrink)

To determine whether dispositions are causally relevant, we have to get clear about what causal relevance is. Several characteristics of causal relevance have been suggested, including Explanatory Power, Counterfactual Dependence, Lawfullness, Exclusion, Independence, and Minimal Sufficiency. Different accounts will yield different answers about the causal relevance of dispositions. However, accounts of causal relevance that are the most plausible, for independent reasons, render the verdict that dispositions are causally relevant.

Upward mobility through the path of higher education has been an article of faith for generations of working-class, low-income, and immigrant college students. While we know this path usually entails financial sacrifices and hard work, very little attention has been paid to the deep personal compromises such students have to make as they enter worlds vastly different from their own. Measuring the true cost of higher education for those from disadvantaged backgrounds, Moving Up without Losing Your Way looks at the (...) ethical dilemmas of upward mobility—the broken ties with family and friends, the severed connections with former communities, and the loss of identity—faced by students as they strive to earn a successful place in society. -/- Drawing upon philosophy, social science, personal stories, and interviews, Jennifer Morton reframes the college experience, factoring in not just educational and career opportunities but also essential relationships with family, friends, and community. Finding that student strivers tend to give up the latter for the former, negating their sense of self, Morton seeks to reverse this course. She urges educators to empower students with a new narrative of upward mobility—one that honestly situates ethical costs in historical, social, and economic contexts and that allows students to make informed decisions for themselves. -/- A powerful work with practical implications, Moving Up without Losing Your Way paves a hopeful road so that students might achieve social mobility while retaining their best selves.

In this paper, I write about nurses of colour who have made significant contributions to nursing, yet are actively ignored in traditional nursing textbooks related to colonized thinking. One consequence of this is that when we think about comparing the disparities of the past to the present day, we see that we have not made much of a difference. The disparity is still huge. I call on all of us as nurses to challenge ourselves to think beyond the box of (...) colonized thought to what we know is true. (shrink)

Epistemology should take seriously the possibility of rationally evaluable changes in conceptual resources. Epistemic decision theory compares belief states in terms of epistemic value. But it's standardly restricted to belief states that don't differ in their conceptual resources. I argue that epistemic decision theory should be generalized to make belief states with differing concepts comparable. I characterize some possible constraints on epistemic utility functions. Traditionally, the epistemic utility of a total belief state has been understood as a function of the (...) epistemic utility of individual (partial) beliefs. The most natural ways of generalizing this account generate a kind of repugnant conclusion. I characterize some possible alternatives, reflecting different epistemic norms. (shrink)

One of the most important aspects of Grice’s theory of conversation is the drawing of a borderline between what is said and what is implic- ated. Grice’s views concerning this borderline have been strongly and influentially criticised by relevance theorists. In particular, it has become increasingly widely accepted that Grice’s notion of what is said is too lim- ited, and that pragmatics has a far larger role to play in determining what is said than Grice would have allowed. (See for (...) example Bezuidenhuit 1996; Blakemore 1987; Carston 1991; Recanati 1991, 1993, 2001; Sperber and Wilson 1986; Wilson and Sperber 1981.) In this paper, I argue that the rejection of Grice has moved too swiftly, as a key line of objection which has led to this rejection is flawed. The flaw, we will see, is that relevance theorists rely on a misunderstanding of Grice’s project in his theory of conversation. I am not arguing that Grice’s versions of saying and implicating are right in all details, but simply that certain widespread reasons for rejecting his theory are based on misconceptions. (shrink)

Accuracy-first epistemology aims to show that the norms of epistemic rationality can be derived from the effective pursuit of accuracy. This paper explores the prospects within accuracy-first epistemology for vindicating “modesty”: the thesis that ideal rationality permits uncertainty about one’s own rationality. I argue that accuracy-first epistemology faces serious challenges in accommodating three forms of modesty: uncertainty about what priors are rational, uncertainty about whether one’s update policy is rational, and uncertainty about what one’s evidence is. I argue that the (...) problem stems from the representation of epistemic decision problems. The appropriate representation of decision problems, and corresponding decision rules, for (diachronic) update policies should be a generalization of decision problems and decision rules for (synchronic) coherence. I argue that extant accounts build in conflicting assumptions about which kinds of information about the believer should be used to structure epistemic decision problems. In particular, extant accounts of update build in a form of epistemic consequentialism. Related forms of epistemic consequentialism have been shown to generate problems for accuracy-first epistemology’s purported justifications of probabilism, conditionalization, and the principal principle. These results are vindicated only with nonconsequentialist epistemic decision theories. I close with suggestive examples of how, with a fully nonconsequentialist representation of epistemic decision problems, accuracy-first epistemology can allow for rational modesty. (shrink)

In this book, McMahon argues that a reading of Kant’s body of work in the light of a pragmatist theory of meaning and language leads one to put community reception ahead of individual reception in the order of aesthetic relations. A core premise of the book is that neo-pragmatism draws attention to an otherwise overlooked aspect of Kant’s "Critique of Aesthetic Judgment," and this is the conception of community which it sets forth. While offering an interpretation of Kant’s aesthetic theory, (...) the book focuses on the implications of Kant’s third critique for contemporary art. McMahon draws upon Kant and his legacy in pragmatist theories of meaning and language to argue that aesthetic judgment is a version of moral judgment: a way to cultivate attitudes conducive to community, which plays a pivotal role in the evolution of language, meaning, and knowledge.

Effective content moderation by social platforms is both important and difficult; numerous issues arise from the volume of information, the culturally sensitive and contextual nature of that information, and the nuances of human communication. Attempting to scale moderation, social platforms are increasingly adopting automated approaches to suppressing communications that they deem undesirable. However, this brings its own concerns. This paper examines the structural effects of algorithmic censorship by social platforms to assist in developing a fuller understanding of the risks of (...) such approaches to content moderation. This analysis shows that algorithmic censorship is distinctive for two reasons: in potentially bringing all communications carried out on social platforms within reach and in potentially allowing those platforms to take a more active, interventionist approach to moderating those communications. Consequently, algorithmic censorship could allow social platforms to exercise an unprecedented degree of control over both public and private communications. Moreover, commercial priorities would be inserted further into the everyday communications of billions of people. Due to the dominance of the web by a few social platforms, this may be difficult or impractical to escape for many people, although opportunities for resistance do exist. (shrink)

In this paper, I make the case for the view that there are many different kinds of dispositions, a view I call dispositional pluralism. The reason I think that this case needs to be made is to temper the tendency to make sweeping generalization about the nature of dispositions that go beyond conceptual truths. Examples of such generalizations include claims that all dispositions are intrinsic, essential, fundamental, or natural.! In order to counter this tendency, I will start by noting the (...) extent to which it is at odds with the semantics of dispositions, according to which there are many kinds of disposition ascriptions. From there, I will try to support a metaphysical claim that there are different kinds of dispositions. To bridge the gap between semantics and metaphysics, I appeal to epistemology. I'll consider the question "when do we have good reason to believe that a disposition ascription is true?" If our disposition ascriptions are true, then we are right about what kinds of dispositions things have, and what kinds of dispositions there are. I claim that our evidence for different kinds of dispositions is on a par; we have reason to believe that various kinds of dispositions are instantiated. (shrink)

Despite advances in theory, often driven by feminist ethicists, research ethics struggles in practice to adequately account for and respond to the agency and autonomy of people considered vulnerable in the research context. We argue that shifts within feminist research ethics scholarship to better characterise and respond to autonomy and agency can be bolstered by further grounding in discourses from the social sciences, in work that confirms the complex nature of human agency in contexts of structural and other sources of (...) vulnerability. We discuss some of the core concepts and critiques emerging from the literature on women and children's agency in under‐resourced settings, highlighting calls to move from individualistic to relational models of agency, and to recognise the ambiguous, value‐laden, and heterogeneous nature of the concept. We then draw out what these conceptual shifts might mean for research ethics obligations and guidance, illustrating our analysis using a case vignette based on research ethics work conducted in South Africa. We conclude that if research practices are to be supportive of agency, it will be crucial to scrutinise the moral judgements which underpin accounts of agency, derive more situated definitions of and responses to agency, and enable people and participants to influence these based on their own experiences and self‐perceptions.

Dugald Stewart claims that conjectural history is ‘the peculiar glory of the latter half of the eighteenth century’. Yet it is hard to see why, in his view, conjectural histories are not merely confabulated just-so stories. This paper examines Stewart's views about the epistemic and moral value of conjectural history.

In this article, we develop a hierarchical Bayesian model of learning in a general type of artificial language‐learning experiment in which learners are exposed to a mixture of grammars representing the variation present in real learners’ input, particularly at times of language change. The modeling goal is to formalize and quantify hypothesized learning biases. The test case is an experiment (Culbertson, Smolensky, & Legendre, 2012) targeting the learning of word‐order patterns in the nominal domain. The model identifies internal biases of (...) the experimental participants, providing evidence that learners impose (possibly arbitrary) properties on the grammars they learn, potentially resulting in the cross‐linguistic regularities known as typological universals. Learners exposed to mixtures of artificial grammars tended to shift those mixtures in certain ways rather than others; the model reveals how learners’ inferences are systematically affected by specific prior biases. These biases are in line with a typological generalization—Greenberg's Universal 18—which bans a particular word‐order pattern relating nouns, adjectives, and numerals. (shrink)

Neurodiversity, the advocacy position that autism and related conditions are natural variants of human neurological outcomes that should be neither cured nor normalized, is based on the assertion that autistic people have unique neurological differences. Membership in this community as an autistic person largely results from clinical identification, or biocertification. However, there are many autistic individuals who diagnose themselves. This practice is contentious among autistic communities. Using data gathered from Wrong Planet, an online autism community forum, this article describes the (...) debate about self-diagnosis amongst autistic self-advocates and argues for the acceptance of the practice in light of the difficulties in verifying autism as a ‘natural kind.’ This practice can counteract discriminatory practices towards and within the autistic community and also work to verfiy autistic self-knowledge and self-expertise. This discussion also has important implications for other neurocommunities, neuroethical issues such as identity and privacy, and the emerging field of critical autism studies. (shrink)

Proponents of “the affective appeal” :787–812, 2014; Zagzebski in Philos Phenomenol Res 66:104–124, 2003) argue that we can make progress in the longstanding debate about the nature of moral motivation by appealing to the affective dimension of affective episodes such as emotions, which allegedly play either a causal or constitutive role in moral judgements. Specifically, they claim that appealing to affect vindicates a version of Motivational Internalism—roughly, the view that there is a necessary connection between moral judgment and motivation—that is (...) both more empirically respectable and less theoretically controversial than non-affective versions. We here argue that the affective appeal fails: versions of Internalism which appeal to affect are neither more empirically supported, nor clearly less controversial, than versions of Internalism which make no such appeal. Although affect doubtless has an important role to play in explaining moral motivation, we are sceptical that establishing any such role advances the debate. (shrink)

In this paper, I draw a parallel between the stability of physical systems and that of economic ones, such as the US financial system. I argue that the use of equilibrium assumptions is central to the analysis of dynamic behavior for both kinds of systems, and that we ought to interpret such idealizing strategies as footholds for causal exploration and explanation. Our considerations suggest multi-scale modeling as a natural home for such reasoning strategies, which can provide a backdrop for the (...) assessment and prevention of financial crises. Equilibrium assumptions are critical elements of the epistemic scaffolding that make up multi-scale models, which we should understand as a means of constructing explanations of dynamic behavior.

The current qualitative study investigated prevalence and types of academic integrity violations in psychology graduate students and solicited student recommendations for how academic institutions, professors, and peers may act to discourage or prevent its occurrence. Students were recruited through email lists and asked to participate in an online study with a series of open-ended questions assessing integrity violations and prevention recommendations. Results revealed academic integrity violations were relatively infrequent and most were of relatively low severity. Common antecedents to integrity violations (...) included inadequate preparation, task difficulty, and external stressors such as health ailments that interfered with preparation. Most violators reported engaging in a rational decision making process, weighing the pros and cons of cheating, and most did not reveal the violation to anyone. The majority of violations resulted in no negative consequences to the student and 44 % reported they would do it again. Students recommended better dissemination of integrity policies, greater oversight of graduate students, harsher punishments for violations, and consistent reporting of violations as prevention strategies. Results highlight how academic dishonesty in psychology graduate students may be a product of multiple time and resource demands, coupled with low self-efficacy to meet or negotiate these demands. Despite reports of external pressures being the top reason for academic integrity violations, few recommendations focused on decreasing external pressures as a mechanism to curb cheating. (shrink)

Promiscuous realism is the thesis that there are many equally legitimate ways of classifying the world’s entities. Advocates of promiscuous realism are typically taken to hold the further the- sis, often undistinguished, that kind terms usefully deployed in scientific generalisations are no more natural than those deployed for any other purposes. Call this further thesis promiscuous nat- uralism. I here defend a version of promiscuous realism which denies promiscuous naturalism. To do so, I introduce the notion of a promiscuous kind: (...) a kind that is maximally usefully referenced in predictive and explanatory generalisations, none of which are scientific generalisations. I first defend the claim that pain is a promiscuous kind before extending these considerations to everyday mental kinds more generally. I draw on further reflections from both everyday life and contem- porary psychology to make credible the novel suggestion that our everyday theory of our minds is for the explanation and prediction of individuals. Combined with the complex idiosyncrasy of individual minds, this suggested aim of everyday theory gives us reason to think that promiscuity is prevalent among everyday mental kinds. (shrink)

The proper object of global health governance should be the common good, ensuring that all people have the opportunity to flourish. A well-organized global society that promotes the common good is to everyone’s advantage. Enabling people to flourish includes enabling their ability to be healthy.

Current GHG fails to support human flourishing, diminishes health capabilities and thus does not serve the common good. The provincial globalism theory of (...) health governance proposes a Global Health Constitution and an accompanying Global Institute of Health and Medicine that together propose to transform health governance. Multiple lines of empirical research suggest that these institutions would be effective, offering the most promising path to a healthier, more just world. (shrink)

Can we extend accuracy-based epistemic utility theory to imprecise credences? There's no obvious way of proceeding: some stipulations will be necessary for either (i) the notion of accuracy or (ii) the epistemic decision rule. With some prima facie plausible stipulations, imprecise credences are always required. With others, they’re always impermissible. Care is needed to reach the familiar evidential view of imprecise credence: that whether precise or imprecise credences are required depends on the character of one's evidence. I propose an epistemic (...) utility theoretic defense of a common view about how evidence places demands on imprecise credence: that your spread of credence should cover the range of chance hypotheses left open by your evidence. I argue that objections to the form of epistemic utility theoretic argument that I use will extend to the standard motivation for epistemically mandatory imprecise credences. (shrink)

Neurosurgery for psychiatric disorders, also sometimes referred to as psychosurgery, is rapidly evolving, with new techniques and indications being investigated actively. Many within the field have suggested that some form of guidelines or regulations are needed to help ensure that a promising field develops safely. Multiple countries have enacted specific laws regulating NPD. This article reviews NPD-specific laws drawn from North and South America, Asia and Europe, in order to identify the typical form and contents of these laws and to (...) set the groundwork for the design of an optimal regulation for the field. Key challenges for this design that are revealed by the review are how to define the scope of the law, what types of regulations are required, and how to approach international harmonization given the potential migration of researchers and patients.

Part graphic novel, part feminist and philosophical analysis, The Pregnancy ≠ Childbearing Project explores how pregnancy can be a meaningful and distinct phenomenon from childbirth and does not equate with childbearing or the production of children.

Background: The public domain of midwifery practice, represented by the educational and hospital institutions could be blamed for a subconscious ethical dilemma for midwifery practitioners. The result of such tension can be seen in complaints from maternity service users of dehumanised care. When expectations are not met, women report dehumanising experiences that carry long term consequences to both them and their child. Objectives: To revisit the ethical foundation of midwifery practice to reflect the feminist Ethic of Care and reframe what (...) is valuable to women and midwives during the childbirth experience. Research Design: A comprehensive literature review is presented from the midwifery and feminist ethics discourse. Ethical Considerations: Nil to report. Findings: Women are vulnerable during childbirth as they need care, yet they prioritise elements of relationship in their experience. The Ethic of Care approach equalises the relationship between the midwife and the woman, providing the space for relationship building and allowing midwives to meet the expectations of their accepted responsibility. Discussion: Some midwives manage to balance the demands of the institution with the needs of the woman. This is described as both an emotional and professionally challenging balancing act. Conclusion: Until there is a formal acknowledgement of the different ethical approach to midwifery practice from within the profession and the Institution, midwifery identity and practice will continue to be compromised.

Because of risks of essentialism and homogenization, feminist theorists frequently avoid making precise ontological claims, especially in regard to specifying bodily connections and differences among women. However well-intentioned, this trend may actually run counter to the spirit of intersectionality by shifting feminists' attention away from embodiment, fostering oppressor-centric theories, and obscuring privilege within feminism. What feminism needs is not to turn from ontological specificity altogether, but to engage a new kind of ontological project that can account for the material complexity (...) of social space in the twenty-first century. Taking inspiration from the phenomenological concept of flesh as well as ecofeminism and María Lugones's theory of the colonial/modern gender system, this essay argues that our own flesh is related to that of others through lines of intercorporeal relations that collectively form topographies of flesh. When we attend to those material relationships present in a particular locality at a point in time, we are able to recognize topographical aggregates of beings that can serve as a basis for this new feminist ontology. An example from Toni Morrison's Beloved involving a human woman and a nonhuman one is used as a paradigm for thinking ontological connection and difference at the same time. (shrink)

There is reason for genuine puzzlement about Hume's aim in ‘The Natural History of Religion’. Some commentators take the work to be merely a causal investigation into the psychological processes and environmental conditions that are likely to give rise to the first religions, an investigation that has no significant or straightforward implications for the rationality or justification of religious belief. Others take the work to constitute an attack on the rationality and justification of religious belief in general. In contrast to (...) these views, I argue that Hume aims to establish two important claims in ‘The Natural History of Religion’. First, almost all popular religions, including popular monotheism, are deeply superstitious. Second, superstitious monotheism is incompatible with the variety of theism supported by the argument from design. This incompatibility puts significant pressure on the rational acceptability of popular religions. (shrink)

Against a backdrop of non-ideal political and legal conditions, this article examines the health capability paradigm and how its principles can help determine what aspects of health care might legitimately constitute positive health care rights—and if indeed human rights are even the best approach to equitable health care provision. This article addresses the long American preoccupation with negative rights rather than positive rights in health care. Positive health care rights are an exception to the overall moral range and general thrust (...) of U.S. legal doctrine. Some positive rights to health care have arisen from U.S. Constitutional Eighth Amendment cases and federal and state laws like Medicare, Medicaid, the State Children’s Health Insurance Program, the Emergency Medical Treatment and Active Labor Act, and the Patient Protection and Affordable Care Act. Finally, this article discusses some of the difficulties inherent in implementing a positive right to health care in the U.S. (shrink)

A theory of perception must be capable of explaining the full range of conscious perception, including amodal perception. In amodal perception we perceive the world to contain physical features that are not directly detectable by the sensory receptors. According to the active-externalist theory of perception, amodal perception depends on active engagement with perceptual objects. This paper focuses on amodal visual perception and presents a counter-example to the idea that active-externalism can account for amodal perception. The counterexample involves the experience of (...) so-called ‘impossible objects’, objects experienced in perceptual character as having geometrical properties that no physically real object can have.

This paper examines four interpretations of the observation that humanitarian intervention might be used ‘selectively’ or ‘inconsistently’ in order to elucidate the normative commitments of the deliberative process in international relations. The paper argues that there are several types of concerns that are implicit in the accusation of inconsistency, and only some of them amount to objections to humanitarian intervention as a whole. The paradox of humanitarian intervention is that intervention is prohibited except where the intervention is humanitarian, yet humanitarian (...) reasons never exist in isolation, and it is nearly impossible to determine the real reason for intervention (or any other collective action) in the international arena. The problems revealed by an examination of inconsistency in the example of humanitarian intervention turn out to be general problems with applying the norms of practical reasoning to moral questions dealing with collective agents.

We might wonder whether there is a difference between experiencing an artwork and simply daydreaming. If the latter, would it be a matter of art communicating something or simply providing a backdrop for personal reverie? According to some influential key texts in philosophy, there is a difference. And it matters because our capacity for communicating the kind of thing art communicates, is a capacity linked to the possibility of not feeling alienated from the world and each other. In this chapter (...) we focus on The weather project, which was a site specific installation Olafur Eliasson created at the Tate Modern in 2003. And to consider how this artwork communicates, we adopt a key concept from Immanuel Kant’s aesthetic theory: “aesthetic ideas”. (shrink)

We can assent to a proposition, build a theory around it, base our actions on it, and affirm its truth—without ever taking it to heart. This frequently happens, for example, to recipients of bad news who figure out what is entailed by the news, make appropriate plans, and pass the news on to others—all without really "taking it in." It happens to those who accept a scientific claim without abandoning their more private views of how things work, and it happens (...) to members of a jury who confidently arrive at a verdict of "guilty" yet remain, on some deeper level, unconvinced. Conversely, people may dismiss their prejudices as mere prejudices while continuing to hold onto them, and a friend may acknowledge a remark to be innocuous yet be offended. Such phenomena are widespread, diverse, and philosophically intriguing. They are not simply cases of weak versus strong belief, or belief that something has a low probability versus a high probability ; nor are they cases of accepting on authority what we only partially understand. Rather, in each case, there is certain lack of depth to one's beliefs. (shrink)

Hurley’s is a difficult book to work through—partly because of its length and the complexity of its arguments, but also because each of the ten essays of which it is composed has a rather different starting point and focus, and because few of her arguments achieve real closure. Essay 2 discusses competing interpretations of Kant, essay 4 articulates nonconceptual forms of self-consciousness, essay 5 offers fresh interpretations of commissurotomy patients’ behavior, essay 6 develops an objection to Wittgenstein on rule following, (...) essay 8 attacks an alleged assumption of externalism, and chapter 10 explores the possibility of combining a “motor theory” and a “control theory” of perception. This is a very rich brew, and at least half the challenge this book presents consists in discerning its central argument and conclusion with enough precision to bring criticism to bear. (shrink)
