Background: Falls in older adults are a major public health problem. White matter hyperintensities are highly prevalent in older adults and are a risk factor for falls. In the absence of a cure for WMHs, identifying potential strategies to counteract the risk of WMHs on falls are of great importance. Physical activity is a promising countermeasure to reduce both WMHs and falls risk. However, no study has yet investigated whether PA attenuates the association of WMHs with falls risk. We hypothesized (...) that PA moderates the association between WMHs and falls risk.Methods: Seventy-six community-dwelling older adults aged 70–80 years old were included in this cross-sectional study. We indexed PA using the Physical Activity Score for the Elderly Questionnaire. Falls risk was assessed using the Physiological Profile Assessment, and WMH volume was determined by an experienced radiologist on T2-weighted and PD-weighted MRI scans. We first examined the independent associations of WMH volume and PASE score with PPA. Subsequently, we examined whether PASE moderated the relationship between WMH volume and PPA. We plotted simple slopes to interpret the interaction effects. Age, sex, and Montreal Cognitive Assessment score were included as covariates in all models.Results: Participants had a mean age of 74 years and 54 were female. Forty-nine participants had a Fazekas score of 1, 19 had a score of 2, and 6 a score of 3. Both PASE and WMH volume were each independently associated with PPA score. The interaction model indicated that PASE score moderated the association between WMH volume and PPA, whereby higher PASE score attenuated the association between WMHs and falls risk.Conclusion: PA is an important moderator of falls risk. Importantly, older adults with WMH can reduce their risk of falls by increasing their PA. (shrink)

Because of its complexity, contemporary scientific research is almost always tackled by groups of scientists, each of which works in a different part of a given research domain. We believe that understanding scientific progress thus requires understanding this division of cognitive labor. To this end, we present a novel agent-based model of scientific research in which scientists divide their labor to explore an unknown epistemic landscape. Scientists aim to climb uphill in this landscape, where elevation represents the significance of the (...) results discovered by employing a research approach. We consider three different search strategies scientists can adopt for exploring the landscape. In the first, scientists work alone and do not let the discoveries of the community as a whole influence their actions. This is compared with two social research strategies, which we call the follower and maverick strategies. Followers are biased towards what others have already discovered, and we find that pure populations of these scientists do less well than scientists acting independently. However, pure populations of mavericks, who try to avoid research approaches that have already been taken, vastly outperform both of the other strategies. Finally, we show that in mixed populations, mavericks stimulate followers to greater levels of epistemic production, making polymorphic populations of mavericks and followers ideal in many research domains.

Most accounts of cognitive scaffolding focus on ways that external structure can support or augment an agent’s cognitive capacities. We call cases where the interests of the user are served benign scaffolding and argue for the possibility and reality of hostile scaffolding. This is scaffolding which depends on the same capacities of an agent to make cognitive use of external structure as in benign cases, but that undermines or exploits the user while serving the interests of another agent. We develop (...) criteria for scaffolding being hostile and show by reference to examples including the design features of electronic gambling machines and casino management systems that hostile scaffolding exists and can be highly effective. In cases where the scaffolding is deep and permits the offloading of significant cognitive work, hostile scaffolding exploitatively manipulates cognitive processing itself. Given the extent of human reliance on scaffolding this is an important and neglected vulnerability. [This is an updated version of the paper, added in February 2023.]. (shrink)

Although existing work draws attention to a range of obstacles in realizing fair AI, the field lacks an account that emphasizes how these worries hang together in a systematic way. Furthermore, a review of the fair AI and philosophical literature demonstrates the unsuitability of ‘treat like cases alike’ and other intuitive notions as conceptions of fairness. That review then generates three desiderata for a replacement conception of fairness valuable to AI research: (1) It must provide a meta-theory for understanding tradeoffs, (...) entailing that it must be flexible enough to capture diverse species of objection to decisions. (2) It must not appeal to an impartial perspective (neutral data, objective data, or final arbiter.) (3) It must foreground the way in which judgments of fairness are sensitive to context, i.e., to historical and institutional states of affairs. We argue that a conception of fairness as appropriate concession in the historical iteration of institutional decisions meets these three desiderata. On the basis of this definition, we organize the insights of commentators into a process-structure map of the ethical territory that we hope will bring clarity to computer scientists and ethicists analyzing Fair AI while clearing some ground for further technical and philosophical work.

That the successful development of fully autonomous artificial moral agents (AMAs) is imminent is becoming the received view within artificial intelligence research and robotics. The discipline of Machines Ethics, whose mandate is to create such ethical robots, is consequently gaining momentum. Although it is often asked whether a given moral framework can be implemented into machines, it is never asked whether it should be. This paper articulates a pressing challenge for Machine Ethics: To identify an ethical framework that is both (...) implementable into machines and whose tenets permit the creation of such AMAs in the first place. Without consistency between ethics and engineering, the resulting AMAs would not be genuine ethical robots, and hence the discipline of Machine Ethics would be a failure in this regard. Here this challenge is articulated through a critical analysis of the development of Kantian AMAs, as one of the leading contenders for being the ethic that can be implemented into machines. In the end, however, the development of Kantian artificial moral machines is found to be anti-Kantian. The upshot of all this is that machine ethicists need to look elsewhere for an ethic to implement into their machines. (shrink)

"Gill's and Ryan's Parmenides is, simply, superb: the Introduction, more than a hundred pages long, is transparently clear, takes the reader meticulously through the arguments, avoids perverseness, and still manages to make sense of the dialogue as a whole; there is a fine selective bibliography; and those parts of the translation I have looked at in detail suggest that it too is very good indeed." --Christopher Rowe, _Phronesis_.

Active inference offers a unified theory of perception, learning, and decision-making at computational and neural levels of description. In this article, we address the worry that active inference may be in tension with the belief–desire–intention model within folk psychology because it does not include terms for desires at the mathematical level of description. To resolve this concern, we first provide a brief review of the historical progression from predictive coding to active inference, enabling us to distinguish between active inference formulations (...) of motor control and active inference formulations of decision processes. We then show that, despite a superficial tension when viewed at the mathematical level of description, the active inference formalism contains terms that are readily identifiable as encoding both the objects of desire and the strength of desire at the psychological level of description. We demonstrate this with simple simulations of an active inference agent motivated to leave a dark room for different reasons. Despite their consistency, we further show how active inference may increase the granularity of folk-psychological descriptions by highlighting distinctions between drives to seek information versus reward—and how it may also offer more precise, quantitative folk-psychological predictions. Finally, we consider how the implicitly conative components of active inference may have partial analogues in other systems describable by the broader free energy principle to which it conforms.

Ethical leadership research has primarily relied on social learning and social exchange theories. Although these theories have been generative, additional theoretical perspectives hold the potential to broaden scholars’ understanding of ethical leadership’s effects. In this paper, we examine moral typecasting theory and its unique implications for followers’ leader-directed citizenship behavior. Across two studies employing both survey-based and experimental methods, we offer support for three key predictions consistent with this theory. First, the effect of ethical leadership on leader-directed citizenship behavior is (...) curvilinear, with followers helping highly ethical and highly unethical leaders the least. Second, this effect only emerges in morally intense contexts. Third, this effect is mediated by the follower’s belief in the potential for prosocial impact. Our findings suggest that a follower’s belief that his or her leader is ethical has meaningful, often counterintuitive effects that are not predicted by dominant theories of ethical leadership. These results highlight the potential importance of moral typecasting theory to better understand the dynamics of ethical leadership. (shrink)

This paper focuses on a recently articulated, emergentist conception of ethical naturalism and its commitment to causal efficacy, or the idea that moral properties have causal powers, along with its supporting commitment to moral causation. After I reconstruct the theory, I explain how it offers some interesting theoretical benefits to moral realists in virtue of its commitment to causal efficacy. Then, after locating some examples of moral causation in support of this commitment, I present and respond to five objections to (...) such causation, which all threaten to undermine this support. Lastly, I consider a very serious problem that the theory faces in virtue of positing emergent moral properties as responsible for moral causation – namely, the problem of downward moral causation. I describe this problem in detail and argue that, as it stands, it does not spell doom for the theory. (shrink)

The development of the Functional Genomics Investigation Ontology (FuGO) is a collaborative, international effort that will provide a resource for annotating functional genomics investigations, including the study design, protocols and instrumentation used, the data generated and the types of analysis performed on the data. FuGO will contain both terms that are universal to all functional genomics investigations and those that are domain specific. In this way, the ontology will serve as the “semantic glue” to provide a common understanding of data (...) from across these disparate data sources. In addition, FuGO will reference out to existing mature ontologies to avoid the need to duplicate these resources, and will do so in such a way as to enable their ease of use in annotation. This project is in the early stages of development; the paper will describe efforts to initiate the project, the scope and organization of the project, the work accomplished to date, and the challenges encountered, as well as future plans.

The framework of depicting put forward byClark (2016)offers a schematic vantage point from which to examine iconic language use. Confronting the framework with empirical data, we consider some of its key theoretical notions. Crucially, by reconceptualizing the typology of depictions, we identify an overlooked domain in the literature: “speech-embedded nonverbal depictions,” namely cases where meaning is communicated iconically, nonverbally, and without simultaneously co-occurring speech. In addition to contextualizing the phenomenon in relation to existing research, we demonstrate, with examples from American (...) TV talk shows, how such depictions function in real-life language use, offering a brief sketch of their complexities and arguing also for their theoretical significance. (shrink)

Nurses are experiencing new ethical issues as a result of global developments and changes in health care. With health care becoming increasingly sophisticated, and countries facing challenges of graying population, ethical issues involved in health care are bound to expand in quantity and in depth. Blended learning rather as a combination of multiple delivery media designed to promote meaningful learning. Specifically, this study was focused on two questions: (1) the students’ satisfaction and attitudes as members of a scenario-based learning process (...) in a blended learning environment; (2) the relationship between students’ satisfaction ratings of nursing ethics course and their attitudes in the blended learning environment. In total, 99 senior undergraduate nursing students currently studying at a public nursing college in Taiwan were invited to participate in this study. A cross-sectional survey design was adopted in this study. The participants were asked to fill out two Likert-scale questionnaire surveys: CAAS (Case Analysis Attitude Scale), and BLSS (Blended Learning Satisfaction Scale). The results showed what students felt about their blended learning experiences — mostly items ranged from 3.27—3.76 (the highest score is 5). Another self-assessment of scenario analysis instrument revealed the mean scores ranged from 2.87—4.19. Nearly 57.8% of the participants rated the course ‘extremely helpful’ or ‘very helpful.’ This study showed statistically significant correlations (r = 0.43) between students’ satisfaction with blended learning and case analysis attitudes. In addition, results testified to a potential of the blended learning model proposed in this study to bridge the gap between students and instructors and the one between students and their peers, which are typical of blended learning, and to create meaningful learning by employing blended pedagogical consideration in the course design. The use of scenario instruction enables students to develop critical analysis and problem solving skills through active learning and social exchange of ideas. (shrink)

: Ulysses contracts have faced paternalism objections since they first were proposed. Since the contracts are designed to override a present request from a legally competent patient in favor of a past request made by that patient, enforcement of these contracts was argued to be unjustifiable strong paternalism. Recent legal developments and new theories of practical reasoning suggest that the discussion of Ulysses contracts should be revived. This paper argues that with a proper understanding of the future-directed planning embodied in (...) Ulysses contracts, the charge of strong paternalism can be answered, and the enforcement of some Ulysses contracts may be justified under the rubric of weak paternalism. (shrink)

This paper attempts to fill an epistemological gap in our theorizing about love with a sketch of an epistemology of love that unfolds by addressing Whitney Houston’s famous epistemological questions pertaining to how we can know whether another loves us. After arguing for three possible sources of the knowledge of love, it offers initial answers to how the knowledge of the presence or absence of another’s love can be acquired from the relevant possible sources previously established. These initial answers, though, (...) are unsatisfying because they invite more difficult questions that are then addressed, such as those pertaining to the kinds of things that constitute love’s expressions along with how to detect these expressions given the possibility of false positives. Addressing these questions ultimately leads to a sharpened, Aristotle-inspired account of how to acquire the knowledge of the presence or absence of another’s love by inferring it, respectively, from the successful or failed detection of love’s expressions.

It is common in metaethics today to draw a distinction between “naturalist” and “non-naturalist” versions of moral realism, where the former view maintains that moral properties are natural properties, while the latter view maintains that they are non-natural properties instead. The nature of the disagreement here can be understood in different ways, but the most common way is to understand it as a metaphysical disagreement. In particular, the disagreement here is about the reducibility of moral properties, where the “naturalists” maintain (...) that moral properties are in some way reducible to the lower-level natural properties on which they supervene, while the “non-naturalists” maintain that moral properties are sui generis and robustly irreducible. In this paper I present a novel version of realist ethical naturalism—a view that I call Emergentist Ethical Naturalism—that reveals this common way of understanding the distinction between naturalism and non-naturalism to be flawed by combining a commitment to ethical naturalism with a commitment to the sui generis and robustly irreducible nature of moral properties that typically defines non-naturalism. Then, after presenting the theory and addressing a few worries that one might have about it, I show how it offers some novel, emergence-based responses to the various supervenience challenges that plague moral realism and thereby gives the ethical naturalist a robustly non-reductive option for dealing with these challenges.

Natural language is full of patterns that appear to fit with general linguistic rules but are ungrammatical. There has been much debate over how children acquire these “linguistic restrictions,” and whether innate language knowledge is needed. Recently, it has been shown that restrictions in language can be learned asymptotically via probabilistic inference using the minimum description length (MDL) principle. Here, we extend the MDL approach to give a simple and practical methodology for estimating how much linguistic data are required to (...) learn a particular linguistic restriction. Our method provides a new research tool, allowing arguments about natural language learnability to be made explicit and quantified for the first time. We apply this method to a range of classic puzzles in language acquisition. We find some linguistic rules appear easily statistically learnable from language experience only, whereas others appear to require additional learning mechanisms (e.g., additional cues or innate constraints).

Recent research has shown a memory advantage for minimally counterintuitive concepts, over concepts that are either intuitive or maximally counterintuitive, although the general result is heavily affected by context. Items from one such study were given to subjects who were asked to create novel stories using at least three concepts from a list containing all three types. Results indicated a preference for using MCI items, and further disclosed two styles of usage, an accommodative style and an assimilative style. The results (...) extend recent memory research and suggest extensions to recent theories intended to explain the prevalence of counterintuitive religious concepts. (shrink)

Effective altruism is a growing philosophical and social movement, whose members design their lives in ways aligned with doing the most good that they can do. The main focus of this paper is to explore what effective altruism has to say about the moral obligations people have to do good with their organs, in the face of an organ-shortage problem. It is argued that an effective altruism framework offers a number of valuable theoretical and practical insights relevant to ongoing debate (...) about how to resolve the organ-shortage problem. Its recommendations constitute a plausible and promising strategy for increasing the supply of, and decreasing the demand for, human organs, in a way that protects the global poor. And, many of its recommendations can be implemented into policy without requiring that citizens actually become effective altruists themselves. (shrink)

Identifying patterns in the world requires noticing not only unusual occurrences, but also unusual absences. We examined how people learn from absences, manipulating the extent to which an absence is expected. People can make two types of inferences from the absence of an event: either the event is possible but has not yet occurred, or the event never occurs. A rational analysis using Bayesian inference predicts that inferences from absent data should depend on how much the absence is expected to (...) occur, with less probable absences being more salient. We tested this prediction in two experiments in which we elicited people's judgments about patterns in the data as a function of absence salience. We found that people were able to decide that absences either were mere coincidences or were indicative of a significant pattern in the data in a manner that was consistent with predictions of a simple Bayesian model.

: In 1856, Michael Faraday (1791–1867) conducted nearly a year's worth of research on the optical properties of gold, in the course of which he discovered the first metallic colloids. Following our own discovery of hundreds of the specimens prepared by Faraday for this research, the present paper describes the cognitive role of these "epistemic artifacts" in the dynamics of Faraday's research practices. Analysis of the specimens, Faraday's Diary records, and replications of selected procedures (partly to replace missing kinds of (...) specimens and partly to understand the "tacit knowledge" implicated in Faraday's research) are outlined, and a reconstruction of the events surrounding the initial discovery of metallic colloids is presented.

Effective altruists aim to do the most good that they can do with the resources available to them, without causing themselves or their dependents significant harm thereby. The argument presented in this paper demonstrates that there are no morally relevant dissimilarities between living kidney donation and living kidney selling for effective altruistic reasons. Thus, since the former is allowed, the latter ought to be allowed as well. And, there are important moral differences between living kidney selling for effective altruistic reasons (...) and other reasons for kidney vending, such that standard objections against markets in human kidneys do not attach to those markets designed around principles of effective altruism. The reasonable conclusion to draw from this is that eligible effective altruist kidney donors ought to be allowed to sell their kidneys to others in need, if they so desire. Because of this, law and policy ought to be changed to allow for this exceptional case: current laws that ban kidney selling for everyone, irrespective of their reason for selling, are unjustified.

Does communicative retributivism necessarily negate capital punishment? My answer is no. I argue that there is a place, though a very limited and unsettled one, for capital punishment within the theoretical vision of communicative retributivism. The death penalty, when reserved for extravagantly evil murderers for the most heinous crimes, is justifiable by communicative retributive ideals. I argue that punishment as censure is a response to the preceding message sent by the offender through his criminal act. The gravity of punishment should (...) be commensurate to the preceding criminal message, so that the offender can face up to the nature and significance of his crime. All murders are not the same. To measure up to the most evil and humanity-degrading murderous message, capital punishment should be the counter-message. Next, I argue that capital punishment does not necessarily violate human dignity. The death penalty and torture may both disrupt human dignity, yet in distinct ways. The death penalty terminates life, the vessel that holds together autonomy, while torture directly assaults autonomy. Torture is never permissible as a form of punishment. But death penalty, when used only on the extravagant evildoers, is justifiable, as life is thoroughly degraded by his own evil act. Further, I argue that mercy is integral to communicative retributivists’ theory of capital punishment. (shrink)

What is love? In this paper I argue that love is a psychological syndrome, or an enormously complex cluster of psychological attitudes and dispositions that’s accompanied by a corresponding set of symptoms that flow from it. More specifically, I argue that love is an affectionate loyalty that takes different shapes across cases and that manifests itself in some set of behavioral and emotional expressions, where this set of expressions also varies across cases. After laying down three theoretical constraints that viable (...) theories of love must satisfy, I sketch my syndrome theory of love in detail and then defend it. First, I argue that it has a strong yet defeasible claim to satisfying the three theoretical constraints. Then I defend my theory against two objections that target its extensional adequacy. I conclude that we have good grounds for being optimistic about the theory even though it calls for further development and scrutiny. (shrink)

We conjecture that corporate social responsibility can be indicative of managerial ethics and integrity and examine whether equity investors and financial analysts consider CSR performance when they assess firms’ disclosures of actual and forecasted earnings. We find that only adverse CSR performance affects investors’ assessments of these disclosures. In contrast, we find that both positive and adverse CSR performance affect analysts’ forecast revisions in response to firms’ disclosures. We also find that firms with adverse CSR performance exhibit lower disclosure quality (...) and earnings persistence, but do not find that firms with positive CSR performance exhibit higher levels of both measures. This asymmetric result is consistent with investors’, but not analysts’, assessments of the effect of CSR performance on corporate disclosures. Our results are robust to using a three-stage least squares approach to address endogeneity concerns and to a battery of robustness and sensitivity analyses. Overall, our findings suggest that investors and analysts consider CSR when assessing the information in earnings-related corporate disclosures. (shrink)

This article examines the reasons early Confucians offer to support the belief that clothing is formative of its wearer’s character, as well as the arguments other early Chinese texts raise to object to it. It focuses on early Confucian discourses about three representative items of clothing, including the cap used in the coming-of-age ceremony, the accessories made by jade, and a style of clothing named shenyi 深衣. These cases demonstrate that, in early Confucian thought, clothing is said to be able (...) to shape the wearer’s character by registering in the wearer its moral symbolism with both psychological-cognitive and bodily means. While this emphasis on symbolism also invites objections that undermine the normative status early Confucians want to ascribe to a specific style of clothing, their discourses still enrich the current understanding of Confucian self-cultivation, in terms of both its method and goals.
