AbstractVirtue ethics has many times been suggested as a promising recipe for the construction of artificial moral agents due to its emphasis on moral character and learning. However, given the complex nature of the theory, hardly any work has de facto attempted to implement the core tenets of virtue ethics in moral machines. The main goal of this paper is to demonstrate how virtue ethics can be taken all the way from theory to machine implementation. To achieve this goal, we critically explore the possibilities and challenges for virtue ethics from a computational perspective. Drawing on previous conceptual and technical work, we outline a version of artificial virtue based on moral functionalism, connectionist bottom–up learning, and eudaimonic reward. We then describe how core features of the outlined theory can be interpreted in terms of functionality, which in turn informs the design of components necessary for virtuous cognition. Finally, we present a comprehensive framework for the technical development of artificial virtuous agents and discuss how they can be implemented in moral environments.

<b><i>Introduction:</i></b> A disturbed sense of self is frequently discussed as an etiological factor for delusion symptoms in psychosis. Phenomenological approaches to psychopathology posit that lacking the sense that the self is localized within one’s bodily boundaries (disembodiment) is one of the core features of the disturbed self in psychosis. The present study examines this idea by experimentally manipulating the sense of bodily boundaries. <b><i>Methods:</i></b> Seventy-three patients with psychosis were randomly assigned to either a 10-min, guided self-massage in the experimental group (EG) to enhance the sense of bodily boundaries or a control group (CG), which massaged a fabric ring. Effects on an implicit measure (jumping to conclusion bias; JTC) and an explicit measure (Brief State Paranoia Checklist; BSPC) of delusion processes were assessed. The JTC measures the tendency to make a decision with little evidence available, and the BSPC explicitly measures the approval of paranoid beliefs. <b><i>Results:</i></b> Patients in the EG showed a lower JTC (<i>M</i> = 4.11 draws before decision) than the CG (<i>M</i> = 2.43; Cohen’s <i>d</i> = 0.64). No significant difference in the BSPC was observed. <b><i>Discussion/Conclusion:</i></b> Our results indicate that enhancing the sense of body boundaries through a self-massage can reduce an implicit bias associated with delusional ideation and correspondingly support the idea that disembodiment might be a relevant factor in the formation of psychotic symptoms.

Core Features

In this paper we argue that our comprehension of musical participation—the complex network of interactive dynamics involved in collaborative musical experience—can benefit from an analysis inspired by the existing frameworks of dynamical systems theory and coordination dynamics. These approaches can offer novel theoretical tools to help music researchers describe a number of central aspects of joint musical experience in greater detail, such as prediction, adaptivity, social cohesion, reciprocity, and reward. While most musicians involved in collective forms of musicking already have some familiarity with these terms and their associated experiences, we currently lack an analytical vocabulary to approach them in a more targeted way. To fill this gap, we adopt insights from these frameworks to suggest that musical participation may be advantageously characterized as an open, non-equilibrium, dynamical system. In particular, we suggest that research informed by dynamical systems theory might stimulate new interdisciplinary scholarship at the crossroads of musicology, psychology, philosophy, and cognitive (neuro)science, pointing toward new understandings of the core features of musical participation.

Meter is one of the core features of music perception. It is the cognitive grouping of regular sound sequences, typically for every 2, 3, or 4 beats. Previous studies have suggested that one can not only passively perceive the meter from acoustic cues such as loudness, pitch, and duration of sound elements, but also actively perceive it by paying attention to isochronous sound events without any acoustic cues. Studying the interaction of top-down and bottom-up processing in meter perception leads to understanding the cognitive system’s ability to perceive the entire structure of music. The present study aimed to demonstrate that meter perception requires the top-down process (which maintains and switches attention between cues) as well as the bottom-up process for discriminating acoustic cues. We created a “biphasic” sound stimulus, which consists of successive tone sequences designed to provide cues for both the triple and quadruple meters in different sound attributes, frequency, and duration, and measured how participants perceived meters from the stimulus in a five-point scale (ranged from “strongly triple” to “strongly quadruple”). Participants were asked to focus on differences in frequency and duration. We found that well-trained participants perceived different meters by switching their attention to specific cues, while untrained participants did not. This result provides evidence for the idea that meter perception involves the interaction between top-down and bottom-up processes, which training can facilitate.

We created a “biphasic” sound stimulus, which consists of successive tone sequences designed to provide cues for both the triple and quadruple meters in different sound attributes, frequency, and duration. Participants were asked to focus on either frequency or duration of the stimulus, and to answer how they perceived meters on a five-point scale (ranged from “strongly triple” to “strongly quadruple”). As a result, we found that participants perceived different meters by switching their attention to specific cues. This result adds evidence to the idea that meter perception involves the interaction between top-down and bottom-up processes.

Background Lewy body dementia is the second most common form of age-related neurodegenerative dementia. It has two forms: dementia with Lewy bodies and Parkinson's disease dementia. Methods There are specific core symptoms associated with dementia with Lewy bodies. Optimum care requires awareness of the features associated with these, as well as appropriate support and management strategies, which are provided in this article. Results The core features of dementia with Lewy bodies are visual hallucinations, cognitive fluctuations, Parkinsonism and rapid eye movement sleep behaviour disorder. Appropriate psychosocial strategies includes psychoeducation, social support and environmental modification. Adoption of these approaches can reduce adverse outcomes. Conclusions The core features of dementia with Lewy bodies can significantly impair quality of life. Nursing and residential care staff are ideally placed to address this through the implementation of psychosocial strategies both directly, and through the provision of psychoeducation for family caregivers.

Interfirm Collaboration

The utilization of advanced information technologies (IT) in interfirm collaboration has been thematic in current literature. Although conventional wisdom perceives that IT systems facilitate supply chain collaboration, this research provides an alternative perspective. Drawing on resource-based view and contingency ‘fit’ theory, the study investigates a model of relationships that specify how environmental uncertainty factors influence the nature of the association of two critical but distinctive IT capabilities with collaboration. Findings corroborate the positive association between collaboration and B2B e-commerce and IT analytic capability. However, demand unpredictability enhances the IT analytic capability-collaboration relationship while detracting from the B2B e-commerce-collaboration association. Notably, the study did not find any moderating influence of another critical uncertainty factor, technological turbulence. The findings reveal the complex nature of IT-collaboration relationships and provide managers a framework for understanding the uncertainty contexts under which specific information technologies with various functionalities may be more appropriately leveraged to derive benefits.

Wrong Action

Moral psychology as a discipline is centrally concerned with psychological issues that arise in connection with the moral evaluation of actions. It deals with the psychological presuppositions of valid morality, that is, with assumptions it seems necessary for us to make in order for there to be such a thing as objective or binding moral requirements: for example, if we lack free will or are all incapable of unselfishness, then it is not clear how morality can really apply to human beings. Moral psychology also deals with what one might call the psychological accompaniments of actual right, or wrong, action, for example, with questions about the nature and possibility of moral weakness or self-deception, and with questions about the kinds of motives that ought to motivate moral agents. Moreover, in the approach to ethics known as ‘virtue ethics’ questions about right and wrong action merge with questions about the motives, dispositions, and abilities of moral agents, and moral psychology plays a more central role than it does in other forms of ethical theory.
