Among the many applications of artificial intelligence (AI), virtual assistants are one of the tools most likely to grow in the future. The development of these systems may play an increasingly important role in many facets of our lives. Therefore, given their potential importance and present and future weight, it is worthwhile to analyze what kind of challenges they entail. In this chapter, we will provide an overview of the ethical aspects of artificial virtual assistants. First, (...) we provide a conceptual clarification of the term ‘virtual assistant’, including different types of interfaces and recommender systems. Second, we address three ethical issues related to the deployment of these systems: their effects on human agency and autonomy and the subsequent cognitive dependence they would generate; the human obsolescence that may cause a generalized extension of the dependence problem; and the invasions of privacy that virtual assistants may cause. Finally, we outline the debates about the use of virtual assistants to improve human moral decisions and some areas in which these systems can be applied. (shrink)

Virtual assistants (VAs), like Amazon’s Alexa, Google’s Assistant, and Apple’s Siri, are on the rise. However, despite allegedly being ‘assistants’ to users, they ultimately help firms to maximise profits. With more and more tasks and leeway bestowed upon VAs, the severity as well as the extent of conflicts of interest between firms and users increase. This article builds on the common law field of fiduciary law to argue why and how regulators should address this phenomenon. First, the (...) functions of VAs resemble established fiduciaries, namely mandataries when they perform tasks on behalf of users, and increasingly advisors whenever they provide recommendations or suggestions. Second, users grant firms deploying VAs ever more discretion over their economic, and more and more significant non-economic interests, such as their health or finances. This delegation of power renders users vulnerable to abuse of power and inadequate performance by firms deploying VAs. Moreover, neither specification or monitoring nor market forces are alternatives that can sufficiently protect users. Thus, regulation is needed, departing from the recognition of the relationship between firms deploying VAs and users as a fiduciary relationship. In the EU, this could be realised through fiduciary requirements for VAs. First and foremost, to adequately protect users from abuse of power by firms deploying VAs, the core fiduciary duty of loyalty should be converted into corresponding fiduciary requirements for VAs, obliging firms to align VAs with their users.

Can Artificial Intelligence be more effective than human instruction for the moral enhancement of people? The author argues that it only would be if the use of this technology were aimed at increasing the individual's capacity to reflectively decide for themselves, rather than at directly influencing behaviour. To support this, it is shown how a disregard for personal autonomy, in particular, invalidates the main proposals for applying new technologies, both biomedical and AI-based, to moral enhancement. As an alternative to these (...) proposals, this article proposes a virtual assistant that, through dialogue, neutrality and virtual reality technologies, can teach users to make better moral decisions on their own. The author concludes that, as long as certain precautions are taken in its design, such an assistant could do this better than a human instructor adopting the same educational methodology. (shrink)

Clark and Fischer argue that people see social robots as depictions of social agents. However, people's interactions with virtual assistants may change their beliefs about social robots. Children and adults with exposure to virtual assistants may view social robots not as depictions of social agents, but as social agents belonging to a unique ontological category.

As commercial virtual assistants become an integrated part of almost every smart device that we use on a daily basis, including but not limited to smartphones, speakers, personal computers, watches, TVs, and TV sticks, there are pressing questions that call for the study of how participants perceive commercial virtual assistants and what relational roles they assign to them. Furthermore, it is crucial to study which characteristics of commercial virtual assistants are perceived as important for (...) establishing affective interaction with commercial virtual assistants. By conducting 26 interviews and performing content analysis of the interview transcripts, this study investigates how the participants in the study perceive, engage, and interact with a variety of commercial virtual assistants. The results lead to better understanding of whether forms of attachment are established or if some sort of relationship is produced between humans and commercial virtual assistants. Key takeaways from our results indicate that, in their current state, the lack of humanlike characteristics in commercial virtual assistants prevents users from forming an emotional attachment to commercial virtual assistants, but this does not deter them from using anthropomorphic language to describe commercial virtual assistants. Yet, our results reveal that users expect commercial virtual assistants’ attributes to be more humanlike in the future. (shrink)

Recent times have seen increasing interest in conversational assistants (e.g., Amazon Alexa) designed to help users in their daily tasks. In military settings, it is critical to design assistants that are, simultaneously, helpful and able to minimize the user’s cognitive load. Here we show that embodiment plays a key role in achieving that goal. We present an experiment where participants engaged in the desert survival task in augmented reality. Participants were paired with a voice assistant, an embodied assistant, (...) or no assistant. The assistants made suggestions verbally throughout the task, whereas the embodied assistant further used gestures and emotion to communicate with the user. Our results indicate that both assistant conditions led to higher performance over the no assistant condition, but the embodied assistant achieved this with less cognitive burden on the decision maker than the non-embodied assistant. We discuss implications for the design of intelligent collaborative systems for the warfighter. (shrink)

Many of our daily activities are now made more convenient and efficient by virtual assistants, and the day when they can be designed to instruct us in certain skills, such as those needed to make moral judgements, is not far off. In this paper we ask to what extent it would be ethically acceptable for these so-called virtual assistants for moral enhancement to use subtle strategies, known as “nudges”, to influence our decisions. To achieve our goal, (...) we will first characterise nudges in their standard use and discuss the debate they have generated around their possible manipulative character, establishing three conditions of manipulation. Secondly, we ask whether nudges can occur in moral virtual assistants that are not manipulative. After critically analysing some proposed virtual assistants, we argue in favour of one of them, given that by pursuing an open and neutral moral enhancement, it promotes and respects the autonomy of the person as much as possible. Thirdly, we analyse how nudges could enhance the functioning of such an assistant, and evaluate them in terms of their degree of threat to the subject’s autonomy and their level of transparency. Finally, we consider the possibility of using motivational nudges, which not only help us in the formation of moral judgements but also in our moral behaviour. (shrink)

Psychotherapy with the use of psychedelic substances, including psilocybin, lysergic acid diethylamide (LSD), ketamine, and 3,4-methylenedioxymethamphetamine (MDMA), has demonstrated promise in treatment of post-traumatic stress disorder (PTSD), anxiety, addiction, and treatment-resistant depression. Psychedelic-assisted psychotherapy (PP) represents a unique psychopharmacological model that leverages the profound effects of the psychedelic experience. That experience is characterized by strong dependency on two key factors: participant mindset and the therapeutic environment. As such, therapeutic models that utilize psychedelics reflect the need for careful design that promotes (...) an open, flexible, trusting mindset and a supportive setting. To meet this need, the PP model is increasingly supplemented by auxiliary methods, including meditation, relaxation, visualization or spiritual practices. We suggest virtual reality (VR) as a full-spectrum tool able to capitalize on and catalyze the innately therapeutic aspects of the psychedelic experience, such as detachment from familiar reality, alteration of self-experience, augmentation of sensory perception and induction of mystical-type experiences. This is facilitated by VR’s evidenced capacity to: aid relaxation and reduce anxiety; buffer from external stimuli; promote a mindful presence; train the mind to achieve altered states of consciousness (ASC); evoke mystical states; enhance therapeutic alliance and encourage self-efficacy. While these unique VR features appear promising, VR’s potential role in PP remains speculative due to lack of empirical evidence on the combined use of VR and PP. Given the increased commercial interest in this synergy there is an urgent need to evaluate this approach. We suggest specific VR models and their role within PP protocols to inspire future direction in scientific research, and provide a list of potential disadvantages, side effects and limitations that need to be carefully considered. These include sensory overstimulation, cyber-sickness, triggering memories of past traumatic events as well as distracting from the inner experience or strongly influencing its contents. A balanced, evidence-based approach may provide continuity across all phases of treatment, support transition into and out of an ASC, deepen acute ASC experiences including mystical states and enrich the psychotherapeutic process of integration. We conclude that the potential application of VR in modulating psychedelic-assisted psychotherapy demands further exploration and an evidence-based approach to both design and implementation.

Replication or even modelling of consciousness in machines requires some clarifications and refinements of our concept of consciousness. Design of, construction of, and interaction with artificial systems can itself assist in this conceptual development. We start with the tentative hypothesis that although the word “consciousness” has no well-defined meaning, it is used to refer to aspects of human and animal informationprocessing. We then argue that we can enhance our understanding of what these aspects might be by designing and building (...) class='Hi'>virtual-machine architectures capturing various features of consciousness. This activity may in turn nurture the development of our concepts of consciousness, showing how an analysis based on information-processing virtual machines answers old philosophical puzzles as well enriching empirical theories. This process of developing and testing ideas by developing and testing designs leads to gradual refinement of many of our pre-theoretical concepts of mind, showing how they can be construed as implicitly “architecture-based” concepts. Understanding how humanlike robots with appropriate architectures are likely to feel puzzled about qualia may help us resolve those puzzles. The concept of “qualia” turns out to be an “architecture-based” concept, while individual qualia concepts are “architecture-driven”. (shrink)

Canada and California each introduced legislation to permit medical assistance in dying in June, 2016. Each jurisdiction publishes annual reports on the number of deaths that occurred under their respective legislations in the previous years. The numbers are disturbingly different. In 2021, 486 individuals died under California’s End of Life Option. In the same year 10,064 Canadians died under that country’s Medical Assistance in Dying (MAiD) legislation. California has a slightly larger population than Canada, and while medically assisted deaths as (...) a percentage of total deaths remained virtually unchanged in California from 2020-2021, Canada saw a 30% increase from 2020 to 2021. This essay examines some of the factors propelling Canada down the slippery slope of medically assisted suicide, as well as those that may be keeping California and other US jurisdictions from taking the slide. At a time of increasing pressure in many jurisdictions (both nationally and internationally) to liberalize access to medical assistance in dying, some lessons from this comparative analysis are offered.

IntroductionGeneralized Anxiety Disorder is a prevalent emotional disorder associated with increased dysfunctionality, which has a lasting impact on the individual’s quality of life. Besides medication, Cognitive-Behavioral Therapy represents the golden standard psychotherapeutic approach for GAD, integrating multilevel techniques and various delivery formats that enable the development of tailored treatment protocols. The objective of this study was to compare the efficiency of a standard CBT protocol targeting worries, dysfunctional beliefs, and intolerance of uncertainty with an integrative and multimodal CBT intervention augmented (...) with Virtual Reality.Materials and methodsThis study included 66 participants with moderate GAD symptoms that were randomized to the standard CBT group and the Integrative and Multimodal CBT augmented with VR group. The interventions comprised 10 weekly sessions conducted by trained CBT therapists, including cognitive restructuring, problem-solving, behavioral exposure, and relaxation techniques. Baseline and post-assessments were conducted with both groups. Primary outcome measures included the Hamilton Anxiety Rating Scale and Penn-State Worry Questionnaire to evaluate the severity of GAD symptoms and worries, respectively. Secondary outcomes involved the administration of Automatic Thoughts Questionnaire, Dysfunctional Attitudes Scale and Unconditional Self-Acceptance Questionnaire.ResultsBoth interventions determined statistically significant effects on both primary and secondary outcomes in the expected direction. However, CBTs was associated with higher effect sizes for anxiety and worries, in contrast to IM-VRCBT. Also, secondary analyses revealed positive correlations between changes in anxiety and worries level and the reduction of dysfunctional cognitive processes.ConclusionThis research emphasized the effectiveness of CBT interventions for treating adults with moderate GAD symptomatology. Specifically, both interventions were efficient for reducing anxiety symptomatology present at individuals with GAD. However, regarding cognitive dysfunctions like worries, the standard CBT protocol performed better, as compared to the IM-VRCBT. In addition, we conclude that VR could be integrated within CBT interventions in a single protocol for GAD treatment. (shrink)

Proprioception has a crucial role in promoting or hindering motor learning. In particular, an intact position sense strongly correlates with the chances of recovery after stroke. A great majority of neurological patients present both motor dysfunctions and impairments in kinesthesia, but traditional robot and virtual reality training techniques focus either in recovering motor functions or in assessing proprioceptive deficits. An open challenge is to implement effective and reliable tests and training protocols for proprioception that go beyond the mere position (...) sense evaluation and exploit the intrinsic bidirectionality of the kinesthetic sense, which refers to both sense of position and sense of movement. Modulated haptic interaction has a leading role in promoting sensorimotor integration and it is a natural way to enhance volitional effort. Therefore, we designed a preliminary clinical study to test a new proprioception-based motor training technique for augmenting kinesthetic awareness via haptic feedback. The feedback was provided by a robotic manipulandum and the test involved 7 chronic hemiparetic subjects over three weeks. The protocol included evaluation sessions, that consisted of a psychometric estimate of the subject’s kinesthetic sensation, and training sessions, in which the subject executed planar reaching movements in the absence of vision and under a minimally assistive haptic guidance made by sequences of graded force pulses. The bidirectional haptic interaction between the subject and the robot was optimally adapted to each participant in order to achieve a uniform task difficulty over the workspace. All the subjects consistently improved in the perceptual scores as a consequence of training. Moreover, they could minimize the level of haptic guidance in time. Results suggest that the proposed method is effective in enhancing kinesthetic acuity, but the level of impairment may affect the ability of subjects to retain their improvement in time. (shrink)

Realistic uses of Virtual Reality technology closely integrate user training on virtual objects with VR-assisted user interactions with real objects. This paper shows how the Interactive Theory of Perception may be extended to cover such cases. Virtual objects are explained as concrete models that have an inner generation mechanism, and the ITP is used to explain how VR users can both perceive such local CMs, and perceptually represent remote real objects. Also, concepts of modeling and representation are (...) distinguished. The paper concludes with suggestions as to how the ITP methodology developed here could be extended to iconic external representations and models generally. (shrink)

Assistive Device Art derives from the integration of Assistive Technology and Art, involving the mediation of sensorimotor functions and perception from both, psychophysical methods and conceptual mechanics of sensory embodiment. This paper describes the concept of ADA and its origins by observing the phenomena that surround the aesthetics of prosthesis-related art. It also analyzes one case study, the Echolocation Headphones, relating its provenience and performance to this new conceptual and psychophysical approach of tool design. This ADA tool is designed to (...) aid human echolocation. They facilitate the experience of sonic vision, as a way of reflecting and learning about the construct of our spatial perception. Echolocation Headphones are a pair of opaque goggles which disable the participant’s vision. This device emits a focused sound beam which activates the space with directional acoustic reflection, giving the user the ability to navigate and perceive space through audition. The directional properties of parametric sound provide the participant a focal echo, similar to the focal point of vision. This study analyzes the effectiveness of this wearable sensory extension for aiding auditory spatial location in three experiments; optimal sound type and distance for object location, perceptual resolution by just noticeable difference, and goal-directed spatial navigation for open pathway detection, all conducted at the Virtual Reality Lab of the University of Tsukuba, Japan. The Echolocation Headphones have been designed for a diverse participant base. They have both the potential to aid auditory spatial perception for the visually impaired and to train sighted individuals in gaining human echolocation abilities. Furthermore, this Assistive Device artwork instigates participants to contemplate on the plasticity of their sensorimotor architecture. (shrink)

Molecular models are typical topics of chemical research depending on the technical standards of observation, computation, and representation. Mathematically, molecular structures have been represented by means of graph theory, topology, differential equations, and numerical procedures. With the increasing capabilities of computer networks, computational models and computer-assisted visualization become an essential part of chemical research. Object-oriented programming languages create a virtual reality of chemical structures opening new avenues of exploration and collaboration in chemistry. From an epistemic point of view, (...) class='Hi'>virtual reality is a new computer-assisted tool of human imagination and recognition. (shrink)

Over recent years, brain-computer interface (BCI) has emerged as an alternative communication system between the human brain and an output device. Deciphered intents, after detecting electrical signals from the human scalp, are translated into control commands used to operate external devices, computer displays and virtual objects in the real-time. BCI provides an augmentative communication by creating a muscle-free channel between the brain and the output devices, primarily for subjects having neuromotor disorders, or trauma to nervous system, notably spinal cord (...) injuries (SCI), and subjects with unaffected sensorimotor functions but disarticulated or amputated residual limbs. This review identifies the potentials of electroencephalography (EEG) based BCI applications for locomotion and mobility rehabilitation. Patients could benefit from its advancements such as wearable lower-limb (LL) exoskeletons, orthosis, prosthesis, wheelchairs, and assistive-robot devices. The EEG communication signals employed by the aforementioned applications that also provide feasibility for future development in the field are sensorimotor rhythms (SMR), event-related potentials (ERP) and visual evoked potentials (VEP). The review is an effort to progress the development of user’s mental task related to LL for BCI reliability and confidence measures. As a novel contribution, the reviewed BCI control paradigms for wearable LL and assistive-robots are presented by a general control framework fitting in hierarchical layers. It reflects informatic interactions, between the user, the BCI operator, the shared controller, the robotic device and the environment. Each sub layer of the BCI operator is discussed in detail, highlighting the feature extraction, classification and execution methods employed by the various systems. All applications’ key features and their interaction with the environment are reviewed for the EEG-based activity mode recognition, and presented in form of a table. It is suggested to structure EEG-BCI controlled LL assistive devices within the presented framework, for future generation of intent-basedmultifunctional controllers. Despite the development of controllers, for BCI-based wearable or assistive devices that can seamlessly integrate user intent, practical challenges associated with such systems exist and have been discerned, which can be constructive for future developments in the field.

Conversational artificial agents and artificially intelligent voice assistants are becoming increasingly popular. Digital virtual assistants such as Siri, or conversational devices such as Amazon Echo or Google Home are permeating everyday life, and are designed to be more and more humanlike in their speech. This study investigates the effect this can have on one’s conformity with an AI assistant. In the 1950s, Solomon Asch’s already demonstrated the power and danger of conformity amongst people. In these classical experiments (...) test persons were asked to answer relatively simple questions, whilst others pretending to be participants tried to convince the test person to give wrong answers. These studies were later replicated with embodied robots, but these physical robots are still rare. In light of our increasing reliance on AI assistants, this study investigates to what extent an individual will conform to a disembodied virtual assistant. We also investigate if there is a difference between a group that interacts with an assistant that communicates through text, one that has a robotic voice and one that has a humanlike voice. The assistant attempts to subtly influence participants’ final responses in a general knowledge quiz, and we measure how often participants change their answer after having been given advice. Results show that participants conformed significantly more often to the assistant with a human voice than the one that communicated through text. (shrink)

In her paper, The case for physician assisted suicide: not proven, Bonnie Steinbock argues that the experience with Oregon’s Death with Dignity Act fails to demonstrate that the benefits of legalising physician assisted suicide outweigh its risks. Given that her verdict is based on a small number of highly controversial cases that will most likely occur under any regime of legally implemented safeguards, she renders it virtually impossible to prove the case for physician assisted suicide. In this brief paper, we (...) suggest some ways that may enable us to weigh the risks and benefits of legalisation more fairly and, hopefully, allow us to close the case for physician assisted suicide.

Although artificial intelligence has been given an unprecedented amount of attention in both the public and academic domains in the last few years, its convergence with other transformative technologies like cloud computing, robotics, and augmented/virtual reality is predicted to exacerbate its impacts on society. The adoption and integration of these technologies within industry and manufacturing spaces is a fundamental part of what is called Industry 4.0, or the Fourth Industrial Revolution. The impacts of this paradigm shift on the human (...) operators who continue to work alongside and symbiotically with these technologies in the industry bring with it novel ethical issues. Therefore, how to design these technologies for human values becomes the critical area of intervention. This paper takes up the case study of robotic AI-based assistance systems to explore the potential value implications that emerge due to current design practices and use. The design methodology known as Value Sensitive Design (VSD) is proposed as a sufficient starting point for designing these technologies for human values to address these issues. (shrink)

ABSTRACT Schmidt introduces the Aristotelian term “koinonia” as denoting a political community which aims to achieve a common good for society as a whole. A good that promotes the flourishing of every party involved. In addition, Schmidt adopts further insight about the term by engaging more thoroughly in discourse about it, realising that this easily extends to the term taking on tenets of communities such as a family. Within family, the terms address even more specific relationships, such as husband and (...) wife, parents and children, sibling relationships, etc. Essentially, Aristotle’s premise of common good persists even in these specific relationships, so much so that Schmidt highlights the pillars which sustain the pursuit of the common good. These pillars are justice, fairness and reciprocity, all grounded in good will and fellowship. This goodwill and fellowship among African parents in a community is to assist each other in raising children in the community and ensure they are grounded in African values, hence the African proverb “a single hand cannot raise a child”. In fact, biological parents may draw from the knowledge of the elderly in the community who can assist in instilling values in the youth. The importance of this is that the elderly in African communities are valued not only as those who sustain order in the community, but are also the custodians of African value systems which younger generations should ideally be grounded in. With the introduction of technology, the digital divide seems to be presenting a challenge when it comes to the solidarity of African parents, as a village, raising their children. Hence, a strategy is required for modern African parents to not abandon this solidarity afforded by their cultural values. The communal way of raising their children should persist in order to preserve the African value of parental solidarity in raising children, even in the midst of what technology and the digital divide presents to the African community.

In the wake of the Corrupted Blood incident, which afflicted the massively multiplayer online computer role-playing game World of Warcraft in 2005, it has been suggested that both, the incident itself and massively multiplayer online computer role-playing games in general, can be utilised to inform and assist real-world epidemic and public health research. In this paper, I engage critically with these claims.

In lieu of an abstract, here is a brief excerpt of the content:Learning in Dramatic and Virtual Worlds:What Do Students Say About Complementarity and Future Directions?John O'Toole (bio) and Julie Dunn (bio)A top financial backer has arrived to determine which team of computer interaction designers has developed the most exciting and innovative proposal for the Everest component of the Virtually Impossible Computer Company's Conquerors of the World Series. Tension is high as the presentations begin, but this tension soon turns (...) to outright conflict as some proposals suggest George Mallory as the conqueror, and the financial backer will have none of him. The backer, it seems, has her own agenda and is determined to allow for only one view of history—the one that records Sir Edmund Hillary as a New Zealand hero and the only real conqueror of the tallest mountain on earth. The designers become more and more agitated until suddenly someone bangs their hand on the table and calls out, "Hang on... just because you've got the money doesn't mean... kids need to learn about both these men... they need to learn about history." With that the drama is cut by the teacher. The deep understandings about "history's purchased page" that can be generated when drama and computers are brought together for learning have been made explicit... but could these same outcomes have been achieved using just one of these approaches?IntroductionThe research explored within this article was generated as part of the Media Station, a project funded by the Australasian Collaborative Research Centre for Interaction Design (ACID), with an overall mission to investigate the potential of massively multiplayer online games for learning. This particular subproject, History's Purchased Page, saw researchers from interaction design [End Page 89] and drama education come together with a group of young learners to investigate their perceptions of the complementarity of computers and live classroom drama and to brainstorm future possibilities for applying computer-based technologies to drama-based learning. We sought to discover the following:• What do young learners say about how they experience and value learning in a context involving a combination of drama and computers?• What ideas do these young learners have about how future technologies might enrich the complementarity of this combination?As the drama researchers involved in this project, we had been experimenting with this perhaps slightly unusual combination for over a decade by incorporating computers into a number of our drama units within our primary textbook Pretending to Learn.1 Our goal in these experimentations had always been to enrich the classroom drama experience by taking advantage of the information capacity of the Internet and other computer-based resources, including databases. For example, we had used The First Fleet Database2 to support a drama unit where the learners take on the role of convicts arriving in Australia in 1788. We discovered that this material, combined with other documentation and historical materials available via the Internet, greatly enhanced not only the historical accuracy of the work but also the level of engagement experienced by the learners when in role. Therefore, we were very keen to extend this work by exploring new possibilities and were especially keen to develop a better understanding of what the learners made of this interactivity.In recent years the partnering of these two quite different approaches to learning has developed quite a research following, and a number of drama teachers and researchers have become interested in the complementarity of these ways of learning.3 At the same time, researchers and designers from the field of computer-assisted learning have also noted these connections. This goes back to the work of Brenda Laurel, who first drew attention to the intriguing links between computers and theatre in her now famous text Computers as Theatre.4 With the rapid growth of interactive learning tools such as 3-D immersive worlds, blogs, and online voice and text chat spaces, the opportunities for exploration of these connections have also grown, with each of these offering exciting new possibilities when used in conjunction with the highly interactive and engaging strategies of process drama.Process drama is a way of group learning, through whole-class improvised drama, with students (and sometimes the...

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Music Education in an Age of Virtuality and Post-Truth by Paul WoodfordPanagiotis A. KanellopoulosPaul Woodford, Music Education in an Age of Virtuality and Post-Truth (New York, Routledge, 2018)This book is provocative. And challenging. It is written with passion, aiming to induce controversy. And with good reason. For we live in times when populism professes an illusionary sense of community, invoking a seemingly 'anti-systemic' but highly hypocritical, racist, and (...) sexist discourse;1 in times where "bullshitting"2 has advanced to the highest governmental levels in many countries; in times where "authoritarian neoliberal statism"3 becomes the new status quo, inducing a scandalous increase of economic inequalities, forcing large populations to live precarious lives; in times where privatization of educational services in the context of market-oriented practices impose restrictive and ultimately unjust politics of accountability and performativity;4 in times where instrumentalization of educational ends has taken the lead, assisted by a systematic co-option and misappropriation of notions such as excellence and creativity;5 in times, finally, where spaces that allow for "the sharing (out) of the incalculable,"6 forging unknown potentialities in education, life, and thought, are being destroyed. In such times, Paul Woodford has stepped in, reclaiming his right to speak uncompromisingly.Hannah Arendt has written that "[w]hen men [sic] are deprived of the public space--which is constituted by acting together and then fills of its own accord [End Page 108] with the events and stories that develop into history--they retreat into their freedom of thought."7 Woodford refuses to retreat. He writes as a public intellectual of the highest order, committed to upset and not please those in power. A great service that his latest book performs is that it speaks daringly, stirring a debate that helps us all to do away with fear. For as Bertrand Russell has aptly said quite a long time ago, "[I]f thought is to become the possession of many, not the privilege of the few, we must have done with fear. It is fear that holds men [sic] back."8Resisting the "melancholy of inner exile,"9 but not immune to possible accusations of left melancholy, understood as "a refusal to come to terms with the particular character of the present,"10 the author wrote a book that provokes music educators to actively think beyond their sealed and safe world of convictions that is based on ideology-free conceptions of music teaching. Estelle Jorgensen has long ago brought to our attention the urgency of this task: "in an era in which the mindset and political reality have changed dramatically, … there is an urgent need to revisit the political character of music education and the ways in which it needs to address the cultural issues of our day."11Along this pathway, Woodford's book encourages music educators to live and teach as public intellectuals, forging "a democratic purpose for music education"12 that acts against the "anachronistic and formalist conception of music that reduces music education to supply-side economics as children are conceived as either future professional musicians or consumers and not as citizens to be prepared in schools to participate intelligently in the political life of society."13 Woodford articulates a vision of music education "as preparation for adulthood and democratic and global citizenship."14 He strongly advocates an approach that balances performance and creativity-based experiences with a socio-historical study of the social, ideological, and cultural workings of different musics in a wide variety of contexts. He encourages music educators to teach "how music's structural properties and qualities contribute to the shaping of people's perceptions and understandings of themselves and their world,"15 "asking the who, what, when, where, how, to, with, or for whom, and, most importantly of all, why of music."16 He envisions a music classroom that exercises social criticism "directly and self-consciously"17 both through "learning how to make music"18 and through thinking about music. He sees this approach as a tool for raising students' consciousness. Woodford's ultimate vision of music education is one that casts it as a means for cultivating "a justice-oriented" approach...

Ever since the start of the twentieth century, a growing interest and importance of studying fatwas can be noted, with a focus on Arabic printed fatwas (Wokoeck 2009). The scholarly study of end-of-life ethics in these fatwas is a very recent feature, taking a first start in the 1980s (Anees 1984; Rispler-Chaim 1993). Since the past two decades, we have witnessed the emergence of a multitude of English fatwas that can easily be consulted through the Internet (‘e-fatwas’), providing Muslims worldwide (...) with a form of Islamic normative guidance on a huge variety of topics. Although English online fatwas do provide guidance for Muslims and Muslim minorities worldwide on a myriad of topics including end-of-life issues, they have hardly been studied. This study analyses Islamic views on (non-)voluntary euthanasia and assisted suicide as expressed in English Sunni fatwas published on independent—i.e. not created by established organisations—Islamic websites. We use Tyan’s definition of a fatwa to distinguish between fatwas and other types of texts offering Islamic guidance through the Internet. The study of e-fatwas is framed in the context of Bunt’s typology of Cyber Islamic Environments (Bunt 2009) and in the framework of Roy’s view on the virtual umma (Roy 2002). ‘(Non-)voluntary euthanasia and assisted suicide’ are defined using Broeckaert’s conceptual framework on treatment decisions at the end of life (Broeckaert 2008). We analysed 32 English Sunni e-fatwas. All of the e-fatwas discussed here firmly speak out against every form of active termination of life. They often bear the same structure, basing themselves solely on Quranic verses and prophetic traditions, leaving aside classical jurisprudential discussions on the subject. In this respect they share the characteristics central in Roy’s typology of the fatwa in the virtual umma. On the level of content, they are in line with the international literature on Islamic end-of-life ethics. English Sunni e-fatwas make up an influential and therefore important developing body of Islamic orthodox normative authority on end-of-life ethics that is still open for further research. (shrink)

In using conventional methods, he combines inductive and deductive methods as set up for developing mental (...) models from up to down and bottom to up. Because in socio-economic branches it is very difficult and even almost wholly impossible to do experiments in objective reality the experimentation by the assistance of computational intelligence is promising advance in gaining new socioeconomic knowledge in contemporary complex world. Using such new approaches, methods and tools is the main scientific aim of the author. He uses convictive demonstration of successful using these unprecedented possibilities in gaining deeper knowledge about complex evolutionary phenomena. The distinction of such knowledge is against conventional one is consisting in very deep understanding of complex socio-economic dynamics. Using meant knowledge acquisition approaches is promising in quality and in abiding knowledge and skill of single individuals but the extraordinary progress of creative knowledge based society fostered by using them in advanced webs is useful for whole society.

To operate in an unpredictable environment, a vehicle with advanced driving assistance systems, such as a robot or a drone, not only needs to register its surroundings but also to combine data from different sensors into a world model, for which it employs filter algorithms. Such world models, as this article argues with reference to the SLAM problem in robotics, consist of nothing other than probabilities about states and events arising in the environment. The model, thus, contains a virtuality of (...) possible worlds that are the basis for adaptive behavior. The article shows that the current development of these technologies requires new concepts because their complex adaptive behaviors cannot be explained by referring them to mere algorithmic processes. Instead, it proposes the heuristic instrument of microdecisions to designate the temporality of decisions between alternatives that are created by probabilistic procedures of world modeling. Microdecisions are more than the implementation of deterministic processes—they decide between possibilities and, thus, always open up the potential of their otherness. By describing autonomous adaptive technologies with this heuristic, the question of sovereignty inevitably arises. It forces us to re-think what autonomy means when decisions can be automated.

Within dramatherapy and psychodrama, the term ‘de-roling’ indicates a set of activities that assist the subjects of therapy in ‘disrobing’ themselves from their fictional characters. Starting from the psychological needs and the therapeutic goals that ‘de-roling’ techniques address in dramatherapy and psychodrama, this text provides a broader understanding of procedures and exercises that define and ease transitional experiences across cultural practices such as religious rituals and spatial design. After this introductory section, we propose a tentative answer as to why game (...) studies and virtual world research largely ignored processes of ‘roling’ and ‘de-roling’ that separate the lived experience of role-play from our everyday sense of the self. The concluding sections argue that de-roling techniques are likely to become more relevant, both academically and in terms of their practical applications, with the growing diffusion of virtual technologies in social practices. The relationships we can establish with ourselves and with our surroundings in digital virtual worlds are, we argue, only partially comparable with similar occurrences in pre-digital practices of subjectification. We propose a perspective according to which the accessibility and immersive phenomenological richness of virtual reality technologies are likely to exacerbate the potentially dissociative effects of virtual reality applications. This text constitutes an initial step towards framing specific socio-technical concerns and starting a timely conversation that binds together dramatherapy, psychodrama, game studies, and the design of digital virtual worlds.

Information posted by youth in online social media contexts is regularly accessed, downloaded, integrated, and analyzed by academic researchers. The practice raises significant social justice considerations for researchers including issues of representation and equitable distribution of risks and benefits. Use of this type of data for research purposes helps to ensure representation in research of the voices of youth who participate in these online contexts, at times discussing issues that are also under-represented. At the same time, youth whose data are (...) harvested are subject to the risks associated with this research, while receiving little if any direct benefit from the work. These risks include the potential loss of online social community as well as threats to participant rights and wellbeing. This paper explores the tension between the social justice benefit of representation and considerations that would suggest caution, the latter including inequitable distribution of research-related costs and benefits, and the traditional ethics concerns of participant autonomy and privacy in the context of youth participation in online discussions. In the final section, we propose guidelines and considerations for the conduct of online social media research to assist researchers to balance and respect representational and participant rights or wellbeing considerations, especially with youth.

Critics and researchers apply various criteria to evaluate the efficacy of VR, including the conformity of VR environments to the character of place. I wish to add a further test: do VR environments enable thought? The paper thus applies to VR the controversial proposition advanced by Clark and others that thinking, i.e. human cognitive processes, are situated and spatial. As a further term in this mix I introduce the concept of non-place, as elucidated by Augé and propose that non-places can (...) be characterized as unthinking spaces, i.e. spaces that provide little assistance to the thought processes of their occupants. Perhaps non-places only offer thepossibilities afforded by a kind of cognitively impoverished instrumentalism. The conclusion from these propositions is that it is instructive to couch the problematics of VR environments in terms of non-places that do not easily accommodate thought, or thoughtful interaction, were it not that thought thrives on transitions, thresholds and boundary conditions between the strange and the familiar.

United States Army Special Forces who deployed to Iraq in mid-2014, and who were seeking to help Iraqi forces to combat Islamic State faced a considerable challenge: how could a force of fewer than 50 operators provide guidance and support to their Iraqi allies while also keeping in line with Washington’s policy of seeking to avoid any possibility of combat casualties among deployed U.S. Special Forces? Their solution to this dilemma came to be dubbed ‘Remote Advise and Assist’. By cobbling (...) together a system of voice and text communications, cameras, interactive maps and mobile handsets, these Special Forces personnel found they could ‘virtually accompany’ their Iraqi partners into hot zones where U.S. boots on the ground were forbidden. This approach seems to have been extremely successful, but potentially raises a range of ethical concerns. Against the backdrop of a general account of the ethics of employing surrogate forces, this paper explores the ethical questions raised by the practice of ‘Remote Advise and Assist’. (shrink)

This paper focuses on the fact that AI is predominantly portrayed as white—in colour, ethnicity, or both. We first illustrate the prevalent Whiteness of real and imagined intelligent machines in four categories: humanoid robots, chatbots and virtual assistants, stock images of AI, and portrayals of AI in film and television. We then offer three interpretations of the Whiteness of AI, drawing on critical race theory, particularly the idea of the White racial frame. First, we examine the extent to (...) which this Whiteness might simply reflect the predominantly White milieus from which these artefacts arise. Second, we argue that to imagine machines that are intelligent, professional, or powerful is to imagine White machines because the White racial frame ascribes these attributes predominantly to White people. Third, we argue that AI racialised as White allows for a full erasure of people of colour from the White utopian imaginary. Finally, we examine potential consequences of the racialisation of AI, arguing it could exacerbate bias and misdirect concern. (shrink)

A significant stimulus for co-editing a book on AI ethics comes from a collaboration between Francisco Lara and Jan Deckers that started when Francisco spent some time, in 2017, as a visiting researcher in the School of Medicine at Newcastle University (United Kingdom). Both of us had been interested for quite some time in the ethics of human enhancement by biotechnological means. Both saw significant problems with these ambitions and associated technologies, recognising at the same time the value of, and (...) the need for a particular type of human enhancement, the improvement of our moral skills. This collaboration resulted in the idea that artificial intelligence (AI) might potentially fulfil a useful role in this respect, and led to the publication of an article that makes a case for designing and using ‘Artificial Intelligence as a Socratic Assistant for Moral Enhancement’ (Lara and Deckers 2020). Francisco subsequently developed this idea, arguing that such a virtual assistant might be even better than a human being in morally enhancing AI users (Lara 2021), whilst Jan spent some time thinking through the nature of the unnatural or artificial (Deckers 2021). Meanwhile, both of us developed a greater awareness of the moral problems and opportunities of AI in general, and of the urgent need to explore, resolve, and govern the ethical issues raised by AI.

This paper sheds light on the role of digital platform labour in the development of today’s artificial intelligence, predicated on data-intensive machine learning algorithms. Focus is on the specific ways in which outsourcing of data tasks to myriad ‘micro-workers’, recruited and managed through specialized platforms, powers virtual assistants, self-driving vehicles and connected objects. Using qualitative data from multiple sources, we show that micro-work performs a variety of functions, between three poles that we label, respectively, ‘artificial intelligence preparation’, ‘artificial (...) intelligence verification’ and ‘artificial intelligence impersonation’. Because of the wide scope of application of micro-work, it is a structural component of contemporary artificial intelligence production processes – not an ephemeral form of support that may vanish once the technology reaches maturity stage. Through the lens of micro-work, we prefigure the policy implications of a future in which data technologies do not replace human workforce but imply its marginalization and precariousness. (shrink)

The article examines the situation of the presence of virtual voices in modern reality. The voices of virtual assistants model a new relationship between voice and face, with anonymity and depersonalization being a priority. The closeness of the face from the voice peculiar to virtual assistants, the detachment of the voice from the facial "accompaniment", the fundamental possibility of the existence of a voice without a face — all this gives the voice as an anthropological (...) and cultural phenomenon of modernity fundamentally new parameters. Digital "logic" implies a departure from the human logos, which can be clearly seen in the example of the problem of "gender" of artificial assistants. Special attention is paid to the problem of correlation of voice and artificial intelligence. Artificial intelligence as an organizational form of cognition acquires a voice, merges with a voice, becomes a voice. The universal scale of the claims of virtual voices requires theological reflection, because the religious experience of "working" with voices, represented in a wide range of world religions, is able to offer a unique interpretation of the role of the voice in modern times. Internet voices can be called into the liturgical space, where they will be asked to sound in new registers and keys. Digital religion appears as a new liturgical reality, a new common cause. It is significant that the non-spiritual technogenic environment can only offer emptiness — the emptiness of digital dehumanization. Digital-humanitarian unity can be built on the adoption of a spiritual foundation, based on the conclusion of a "pact" on cooperation between the spiritual experience of mankind and cyber-information perspectives.

Feminized AIs designed for in-home verbal assistance are often subjected to gendered verbal abuse by their users. I survey a variety of features contributing to this phenomenon—from financial incentives for businesses to build products likely to provoke gendered abuse, to the impact of such behavior on household members—and identify a potential worry for attempts to criticize the phenomenon; while critics may be tempted to argue that engaging in gendered abuse of AI increases the chances that one will direct this abuse (...) toward human beings, the recent history of attempts to connect video game violence to real-world aggression suggests that things may not be so simple. I turn to Confucian discussions of the role of ritualized social interactions both to better understand the roots of the problem and to investigate potential strategies for improvement, given a complex interplay between designers and device users. I argue that designers must grapple with the entrenched sexism in our society, at the expense of “smooth” and “seamless” user interfaces, in order to intentionally disrupt entrenched but harmful patterns of interaction, but that doing so is both consistent with and recommended by Confucian accounts of social rituals.

Social robots serve people as tutors, caretakers, receptionists, companions, and other social agents. People know that the robots are mechanical artifacts, yet they interact with them as if they were actual agents. How is this possible? The proposal here is that people construe social robots not as social agents per se, but as depictions of social agents. They interpret them much as they interpret ventriloquist dummies, hand puppets, virtual assistants, and other interactive depictions of people and animals. Depictions (...) as a class consist of three physical scenes with part-by-part mappings between them: (a) a base scene (the raw physical artifact), (b) the depiction proper (the artifact construed as a depiction), and (c) the scene depicted (the scene people are to imagine). With social robots, evidence shows people form the same three scenes plus mappings: They perceive the raw machinery of a robot, construe it as a depiction of a character, and, using the depiction as a guide, engage in the pretense that they are interacting with the character depicted. With social robots, people also recognize three classes of agents – the characters depicted, the intended recipients of the depictions (those who view or interact with the robots), and the authorities responsible for the robots (the designers, makers, and owners). Construing social robots as depictions, we argue, accounts for many phenomena not covered by alternative models. (shrink)

There has recently been a surge of development in augmented reality (AR) technologies that has led to an ecosystem of hardware and software for AR, including tools for artists and designers to accelerate the design of AR content and experiences without requiring complex programming. AR is viewed as a key “disruptive technology” and future display technologies (such as digital eyewear) will provide seamless continuity between reality and the digitally augmented. This article will argue that the technologization of human perception and (...) experience of reality, coupled with the development of artificial intelligence (AI)–based natural language assistants, may lead to a secular re‐enchantment of the world, in the sense outlined by Charles Taylor, where human existence is shaped through AR inhabited by advanced personal and social AI agents in the form of digital avatars and daemons, and that enchantment has been persistent throughout the formation of modernity and is being rekindled by the integration of AI in the plane of AR.

An increasing amount of data is now available from public and private sources. Furthermore, the types, formats, and number of sources of data are also increasing. Techniques for extracting, storing, processing, and analyzing such data have been developed in the last few years for managing this bewildering variety based on a structure called a knowledge graph. Industry has devoted a great deal of effort to the development of knowledge graphs, and knowledge graphs are now critical to the functions of intelligent (...) virtual assistants such as Siri, Alexa, and Google Assistant. The goal of the Ontology Summit 2020 was to understand not only what knowledge graphs are but also where they originated, why they are so popular, the current issues, and their future prospects. The summit sessions examined many examples of knowledge graphs and surveyed the relevant standards that exist and are in development for knowledge graphs. The purpose of this Communiqué is to summarize our understanding from the Summit in order to foster research and development of knowledge graphs. (shrink)

This article explores how a focus on ‘student centeredness’ can lead to ‘innovation’ and how innovation can enhance student centeredness. Putting students at the centre of all considerations can unleash their creative and innovative potential. And recent innovations have made it easier to make students the focal point of service delivery. After a description of what we understand under these two guiding concepts, a case study is presented in which an AI-powered Student Virtual Assistant was developed at York University (...) in Toronto, Canada. All steps of the product creation, including envisioning, designing, prototyping, and evaluating are described, as well as the following steps involving maintenance and expansion. (shrink)

More companies are understanding the benefits of designing work to enhance, rather than minimise, the contributions of their employees within human-centred systems. To do this, they require their supportive subsystems (such as training, job, and team design, performance measurement and information) to provide people with the ability, motivation and opportunity to become increasingly involved. Opportunity for involvement will require different communication interfaces, providing data and background information both personally and at the work site or process. In the past few years, (...) the media available for visualisation and communication have become much more numerous and have much greater capabilities. This paper examines the information requirements of certain features of modern manufacturing enterprises—local control, skills, knowledge and training, function allocation and team communications. It then assesses the utility of three broad types of information display—Personal Digital Assistants (PDAs), Multimedia/Closed-circuit Television (CCTV) and Virtual Environments (VEs)—for shopfloor systems.

Speaking with conversational AIs, technologies whose interfaces enable human-like interaction based on natural language, has become a common phenomenon. During these interactions, people form their beliefs due to the say-so of conversational AIs. In this paper, I consider, and then reject, the concepts of testimony-based beliefs and instrument-based beliefs as suitable for analysis of beliefs acquired from these technologies. I argue that the concept of instrument-based beliefs acknowledges the non-human agency of the source of the belief. However, the analysis focuses (...) on perceiving signs and indicators rather than content expressed in natural language. At the same time, the concept of testimony-based beliefs does refer to natural language propositions, but there is an underlying assumption that the agency of the testifier is human. To fill the lacuna of analyzing belief acquisition from conversational AIs, I suggest a third concept: technology-based beliefs. It acknowledges the non-human agency-status of the originator of the belief. Concurrently, the focus of analysis is on the propositional content that forms the belief. Filling the lacuna enables analysis that considers epistemic, ethical, and social issues of conversational AIs without excluding propositional content or compromising accepted assumptions about the agency of technologies.

This article reviews the Dutch societal debate on euthanasia/assisted suicide in dementia cases, specifically Alzheimer's disease. It discusses the ethical and practical dilemmas created by euthanasia requests in advance directives and the related inconsistencies in the Dutch legal regulations regarding euthanasia/assisted suicide. After an initial focus on euthanasia in advanced dementia, the actual debate concentrates on making euthanasia/assisted suicide possible in the very early stages of dementia. A review of the few known cases of assisted suicide of people with so-called (...) early dementia raises the question why requests for euthanasia/assisted suicide from patients in the early stage of Alzheimer's disease are virtually non-existent. In response to this question two explanations are offered. It is concluded that, in addition to a moral discussion on the limits of anticipatory choices, there is an urgent need to develop research into the patient's perspective with regard to medical treatment and care-giving in dementia, including end-of-life care.

This paper seeks to identify, clarify, and perhaps rehabilitate the virtual reality metaphor as applied to the goal of understanding consciousness. Some proponents of the metaphor apply it in a way that implies a representational view of experience of a particular, extreme form that is indirect, internal and inactive (what we call “presentational virtualism”). In opposition to this is an application of the metaphor that eschews representation, instead preferring to view experience as direct, external and enactive (“enactive virtualism”). This (...) paper seeks to examine some of the strengths and weaknesses of these virtuality-based positions in order to assist the development of a related, but independent view of experience: virtualist representationalism. Like presentational virtualism, this third view is representational, but like enactive virtualism, it places action centre-stage, and does not require, in accounting for the richness of visual experience, global representational “snapshots” corresponding to the entire visual field to be tokened at any one time.

In virtually all the developed countries of the Western world, people are living longer and reproducing less. At the same time, costs for the care of the elderly and infirm continue to rise dramatically. Given these facts, it should come as no surprise that we are experi encing an ever-increasing concern with questions relating to the proper care and treatment of the aged. What responsibilities do soci eties have to their aging citizens? What duties, if any, do grown chil dren (...) owe their parents? What markers should we use to determine one's status as "elderly"? Does treatment of pain in aged patients present special medical and/or moral problems? How can the com peting claims of autonomy and optimal medical care be reconciled for elderly persons who require assisted living? When, if ever, should severely demented patients be included in nontherapeutic clinical tri als? These questions, and others of similar interest to those con cerned with the proper treatment of the aged, are discussed in depth in the articles included in this text. The essays in this volume of Biomedical Ethics Reviews fall loosely into two broad categories. The first four articles-those con tributed by Sheila M.

Dialogue systems, from Virtual Personal Assistants such as Siri, Cortana, and Alexa to state-of-the-art systems such as BlenderBot3 and ChatGPT, are already widely available, used in a variety of applications, and are increasingly part of many people’s lives. However, the task of enabling them to use empathetic language more convincingly is still an emerging research topic. Such systems generally make use of complex neural networks to learn the patterns of typical human language use, and the interactions in which (...) the systems participate are usually mediated either via interactive text-based or speech-based interfaces. In human–human interaction, empathy has been shown to promote prosocial behaviour and improve interaction. In the context of dialogue systems, to advance the understanding of how perceptions of empathy affect interactions, it is necessary to bring greater clarity to how empathy is measured and assessed. Assessing the way dialogue systems create perceptions of empathy brings together a range of technological, psychological, and ethical considerations that merit greater scrutiny than they have received so far. However, there is currently no widely accepted evaluation method for determining the degree of empathy that any given system possesses (or, at least, appears to possess). Currently, different research teams use a variety of automated metrics, alongside different forms of subjective human assessment such as questionnaires, self-assessment measures and narrative engagement scales. This diversity of evaluation practice means that, given two DSs, it is usually impossible to determine which of them conveys the greater degree of empathy in its dialogic exchanges with human users. Acknowledging this problem, the present article provides an overview of how empathy is measured in human–human interactions and considers some of the ways it is currently measured in human–DS interactions. Finally, it introduces a novel third-person analytical framework, called the Empathy Scale for Human–Computer Communication (ESHCC), to support greater uniformity in how perceived empathy is measured during interactions with state-of-the-art DSs.
