There is mounting evidence that non-invasive brain stimulation devices - transcranial direct current stimulation and transcranial magnetic stimulation could be used for cognitive enhancement. However, the regulatory environment surrounding such uses of stimulation devices is less clear than for stimulant drugs—a fact that has already been commercially exploited by several companies. In this paper, the mechanism of action, uses and adverse effects of non-invasive neurostimulation devices are reviewed, along with social and ethical challenges pertaining to their use (...) as cognitive enhancements. Two regulatory approaches that could be used to facilitate responsible use of these devices as products and services are outlined. Apart from establishing the urgently needed comprehensive regulatory framework, they might provide a starting point for establishing long term physiological and social effects of enhancement uses of tDCS and TMS.

This book is designed to explain the technical ideas that are taken for granted in much contemporary philosophical writing. Notions like "denumerability," "modal scope distinction," "Bayesian conditionalization," and "logical completeness" are usually only elucidated deep within difficult specialist texts. By offering simple explanations that by-pass much irrelevant and boring detail, Philosophical Devices is able to cover a wealth of material that is normally only available to specialists. The book contains four sections, each of three chapters. The first section is (...) about sets and numbers, starting with the membership relation and ending with the generalized continuum hypothesis. The second is about analyticity, a prioricity, and necessity. The third is about probability, outlining the difference between objective and subjective probability and exploring aspects of conditionalization and correlation. The fourth deals with metalogic, focusing on the contrast between syntax and semantics, and finishing with a sketch of Godel's theorem. Philosophical Devices will be useful for university students who have got past the foothills of philosophy and are starting to read more widely, but it does not assume any prior expertise. All the issues discussed are intrinsically interesting, and often downright fascinating. It can be read with pleasure and profit by anybody who is curious about the technical infrastructure of contemporary philosophy."--p. 4 of cover. (shrink)

Sensory substitution devices provide through an unusual sensory modality (the substituting modality, e.g., audition) access to features of the world that are normally accessed through another sensory modality (the substituted modality, e.g., vision). In this article, we address the question of which sensory modality the acquired perception belongs to. We have recourse to the four traditional criteria that have been used to define sensory modalities: sensory organ, stimuli, properties, and qualitative experience (Grice, 1962), to which we have added the (...) criteria of behavioral equivalence (Morgan, 1977), dedication (Keeley, 2002), and sensorimotor equivalence (O’Regan & Noe¨, 2001). We discuss which of them are fulfilled by perception through sensory substitution devices and whether this favors the view that perception belongs to the substituting or to the substituted modality. Though the application of a number of criteria might be taken to point to the conclusion that perception with a sensory substitution device belongs to the substituted modality, we argue that the evidence leads to an alternative view on sensory substitution. According to this view, the experience after sensory substitution is a transformation, extension, or augmentation of our perceptual capacities, rather than being something equivalent or reducible to an already existing sensory modality. We develop this view by comparing sensory substitution devices to other ‘‘mind-enhancing tools’’ such as pen and paper, sketchpads, or calculators. An analysis of sensory substitution in terms of mind-enhancing tools unveils it as a thoroughly transforming perceptual experience and as giving rise to a novel form of perceptual interaction with the environment.

Despite concerns about the relationships between health professionals and the medical device industry, the issue has received relatively little attention. Prevalence data are lacking; however, qualitative and survey research suggest device industry representatives, who are commonly present in clinical settings, play a key role in these relationships. Representatives, who are technical product specialists and not necessarily medically trained, may attend surgeries on a daily basis and be available to health professionals 24 hours a day, 7 days a week, to provide (...) advice. However, device representatives have a dual role: functioning as commissioned sales representatives at the same time as providing advice on approaches to treatment. This duality raises the concern that clinical decision-making may be unduly influenced by commercial imperatives. In this paper, we identify three key ethical concerns raised by the relationship between device representatives and health professionals: impacts on healthcare costs, the outsourcing of expertise and issues of accountability and informed consent. These ethical concerns can be addressed in part through clarifying the boundary between the support and sales aspects of the roles of device representatives and developing clear guidelines for device representatives providing support in clinical spaces. We suggest several policy options including hospital provision of expert support, formalising clinician conduct to eschew receipt of meals and payments from industry and establishing device registries.

Responsible research and innovation has come to represent a change in the relationship between science, technology and society. With origins in the democratisation of science, and the inclusion of ethical and societal aspects in research and development activities, RRI offers a means of integrating society and the research and innovation communities. In this article, we frame RRI activities through the lens of layers of science and technology governance as a means of characterising the context in which the RRI activity is (...) positioned and the goal of those actors promoting the RRI activities in shaping overall governance patterns. RRI began to emerge during a time of considerable deliberation about the societal and governance challenges around nanotechnology, in which stakeholders were looking for new ways of integrating notions of responsibility in nanotechnology research and development. For this reason, this article focuses on nanotechnology as the site for exploring the evolution and growth of RRI. (shrink)

A new approach to informal rigorous mathematical proof is offered. To this end, algorithmic devices are characterized and their central role in mathematical proof delineated. It is then shown how all the puzzling aspects of mathematical proof, including its peculiar capacity to convince its practitioners, are explained by algorithmic devices. Diagrammatic reasoning is also characterized in terms of algorithmic devices, and the algorithmic device view of mathematical proof is compared to alternative construals of informal proof to show (...) its superiority.

Post COVID-19 infections resulting in long COVID symptoms remain persistent yet neglected in healthcare priorities. Although long COVID symptoms are expected to decline after some time, many people continue to endure its debilitating effects affecting their daily lives. The diversity of characteristics amongst long COVID patients adds to the complexity of communicating personal health predicaments to healthcare providers. Recent research towards building an evidence base for long COVID with the aim of delivering responsive healthcare interventions for long COVID patients has (...) utilised datasets generated from wearable devices. This paper examines the prospects presented by wearable devices for long COVID patients and physicians. It highlights distinct ethical and legal challenges arising from their use in practice. Several recommendations aiming to support their usage amongst long COVID patients are outlined for future research using wearable devices for long COVID treatment. (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)

Resumen: Asociadamente a la complejización del sistema educacional, toman forma procedimientos que buscan su regulación y que, al mismo tiempo, van dando forma a las metas a lograr. En el caso de Chile, en los últimos 50 años se ha constituido un dispositivo de evaluación del sistema educacional de gran alcance, que incluye pruebas nacionales como el SIMCE y la PSU, el Sistema de Evaluación Docente, el Sistema de Acreditación Universitario, la evaluación de la productividad académica, pruebas internacionales como PISA (...) y TIMSS, y la elaboración de rankings de instituciones educacionales. Este dispositivo es una tecnología clave de gubernamentalidad que posibilita regular la conducta de la población. En su constitución se entretejen conocimientos, teóricos y técnicos, provenientes de las ciencias sociales, con preocupaciones y estrategias que buscan el gobierno de la población. Se combinan ciencia social y poder. El dispositivo constituye una tecnología político moral con poderosos efectos performativos que dan forma a lo que asumimos, para todos los efectos prácticos, como la calidad educacional de las diferentes entidades del sistema -estudiantes, escuelas, programas, profesores, universidades, etc.- y que las valoriza en términos de tal calidad. El texto busca articular conceptualmente las operaciones de este dispositivo y sus derivaciones.: Associated with the increasing complexity of the educational system, procedures that seek its regulation take form and, at the same time, shape the goals to be achieved. In the case of Chile, in the last 50 years, a powerful evaluation device for the educational system has been established, which includes national tests such as SIMCE and PSU, the Teacher Evaluation System, the System of University Accreditation, the evaluation of the academic productivity, international tests such as PISA and TIMSS, and the elaboration of rankings of educational institutions. This device is a key technology of governmentality that makes possible to regulate the behavior of the population. In its constitution are interwoven theoretical and technical knowledge from the social sciences and concerns and strategies for the government of the population. Social science and power are combined. The device constitutes a moral and political technology with powerful performative effects that shape what we assume, for all practical purposes, as the educational quality of the different entities of the system -students, schools, programs, professors, universities, etc.-, which are valued in terms of such quality. The paper seeks to articulate theoretically the operations of this device and its derivations. (shrink)

Commitment devices (CDs) can help people overcome self-control problems to act on their plans and preferences. In these arrangements, people willingly make one of their options worse in order to change their own future behaviour, often by setting aside a sum of money that they will forfeit it if they fail to complete the planned action. Such applications of behavioural science have been used to help people stick to healthier lifestyle choices, overcome addictions and adhere to medication; they are (...) acceptable to many patients and even relatively small sums can be effective. Some authors have objected to the use of nudges in healthcare. Engelen has listed nine potential objections to nudges in relation to means (why nudge rather than persuade?), ends (what action is being promoted?) and agents (who is nudging whom?). These objections are shown to lack force in the context of CDs. Instead, an analysis specific to the ethical issues in CDs is employed. CDs exclude certain groups including so-called ‘naifs’ and risk increasing health inequality. CDs may promote the wrong behaviour and people might legitimately change their minds. Intermediaries might encounter perverse incentives. Approaches to overcoming these problems are described and eight key ethical considerations for those considering implementing CDs in the future are described. Altogether this paper illustrates the advantages of appraising the ethics of behavioural science in medicine on a case-by-case basis. (shrink)

This article provides a conceptual and normative framework through which we may understand the potentially ethically significant roles that information generated by neurotechnologies about our brains and minds may play in our construction of our identities. Neuroethics debates currently focus disproportionately on the ways that third parties may (ab)use these kinds of information. These debates occlude interests we may have in whether and how we ourselves encounter information about our own brains and minds. This gap is not yet adequately addressed (...) by most allusions in the literature to potential identity impacts. These lack the requisite conceptual or normative foundations to explain why we should be concerned about such effects or how they might be addressed. This article seeks to fill this gap by presenting a normative account of identity as constituted by embodied self-narratives. It proposes that information generated by neurotechnologies can play significant content-supplying and interpretive roles in our construction of our self-narratives. It argues, to the extent that these roles support and detract from the coherence and inhabitability of these narratives, access to information about our brains and minds engages non-trivial identity-related interests. These claims are illustrated using examples drawn from empirical literature reporting reactions to information generated by implantable predictive BCIs and psychiatric neuroimaging. The article concludes by highlighting ways in which information generated by neurotechnologies might be governed so as to protect information subjects’ interests in developing and inhabiting their own identities.

The Supreme Court”, first published in 1987, is a concise and informative narrative of the highest court in the USA. It contains much that is of interest and probing about the court and the intrigues of its decision-making. Moments abound when the reader is taken on a journey through the humanity of the cases, the erudite corridors of high-law and into the intensely high-strung but level-headed hallowed chambers of the Justices and Justice. What is revealed is the exacting mask of (...) law, the humanity and affectations of those whose burden it is to deliver far-reaching judgment on the American people. However, more revealing of the storyline is, perhaps, not so much the woven narratives contained within the three pages of text as it is the peripheral story (what Gerard Genette called the ‘paratext’) unfolded in the cover wraps, what they contain and the stories they weave. In this paper, I examine the liminal devices of ‘The Supreme Court’. I argue that much of the systemic cognition of the legal system can be divined from a scholarly encounter with these elements. Furthermore, the paratexts of two editions of the book indicate a paradigmatic shift in the legal perception of both the Supreme Court and the author between the periods of publication. This underscores the law not only in its reactive form but also in its dexterity in shifting its position to reflect the reality of its time. On each occasion, it alters the legal consciousness of a nation. Yet, it stays remarkably stable and self-effacing. The essential question is one of deference. It is of great interest that the Chief Justice targets the informed and the interested as opposed to the ignorant and ambivalent. The liminal devices, I observe, are probably as eloquent with this message as the text within. The paratext bears testimony to this. -/- Keywords. (shrink)

The central topic of this paper is a mobile phone application, ‘InformaCam’, which turns metadata from a surveillance risk into a method for the production of public proof. InformaCam allows one to manage and delete metadata from images and videos in order to diminish surveillance risks related to online tracking. Furthermore, it structures and stores the metadata in such a way that the documentary material becomes better accommodated to evidentiary settings, if needed. In this paper I propose InformaCam should be (...) interpreted as a ‘forensic device’. By using the conceptualization of forensics and work on socio-technical devices the paper discusses how InformaCam, through a range of interventions, rearranges metadata into a technology of evidence. InformaCam explicitly recognizes mobile phones as context aware, uses their sensors, and structures metadata in order to facilitate data analysis after images are captured. Through these modifications it invents a form of ‘sensory data forensics'. By treating data in this particular way, surveillance resistance does more than seeking awareness. It becomes engaged with investigatory practices. Considering the extent by which states conduct metadata surveillance, the project can be seen as a timely response to the unequal distribution of power over data. (shrink)

One of the intriguing features of the semantic theories proposed by Jerry Fodor and Jerrold Katz is that they attempt to provide a criterion for semantic anomaly. Ostensibly, the criterion would enable one to determine when a phrase is semantically absurd or incongruous even in cases where the phrase appears to be grammatically proper. For example, phrases such as ‘spinster insecticide’ and ‘female uncle’ would be marked as anomalous in the semantic theory even though they seem grammatically on a par (...) with ‘gaseous insecticide’ and ‘unemployed uncle’.Recently, however, a number of criticisms have been raised concerning the theoretical devices that Fodor and Katz supply for marking such anomalies. In this essay I want to examine these criticisms and suggest a modification of the theories which would answer the critics on this point and, at the same time, significantly enhance the explanatory power of the theories.

This paper uses Actor Network Theory to examine two cases of device‐mediated educational change, one involving a computer‐assisted interactive video module that provided a half‐hour of instruction for a university course, the other an assistive communication device that proved a supposedly retarded pre‐school child to be intelligent. The paper explores how device construction instigated by middle‐level organizational workers can ramify into organizational change, and extends Actor Network theory by augmenting some of its conceptual tools. I argue that the organizational change (...) processes initiated by work on the devices played out in non‐linear ways across the decades‐long careers of their makers, and that to understand them we not only have to look across such extended time frames, but must also consider how agency and identity positions emerge and shift over time through the mediation of devices.

Recent advances in automation technology have increased the opportunity for collaboration between humans and multiple autonomous systems such as robots and self-driving cars. In research on autonomous system collaboration, the trust users have in autonomous systems is an important topic. Previous research suggests that the trust built by observing a task can be transferred to other tasks. However, such research did not focus on trust in multiple different devices but in one device or several of the same devices. (...) Thus, we do not know how trust changes in an environment involving the operation of multiple different devices such as a construction site. We investigated whether trust can be transferred among multiple different devices, and investigated the effect of two factors: the similarity among multiple devices and the agency attributed to each device, on trust transfer among multiple devices. We found that the trust a user has in a device can be transferred to other devices and that attributing different agencies to each device can clarify the distinction among devices, preventing trust from transferring.

Mobile technologies such as tablets, iPads, laptops, netbooks as well as mobile phones with internet connectivity and recording features present new challenges to the academy. In the age of convergence and with the encoding of several features into mobile telephony, private spaces of the classroom can be reconfigured through the mediation of technologies. In most cases, existing rules and regulations of higher education institutions do not comprehensively address these challenges. The introduction of new technologies into the classroom has been often (...) framed historically as vital and relevant for a progressive academic society or as part of a national imperative to transform the ways in which the authors access and engage with knowledge. This paper surveys British universities to examine how they govern the phenomenon of recording content through mobile technologies. The results reveal a pervasive use of mobile devices in UK universities and clear divergences in approaches to enacting mobile device-specific policies to govern the usage of these technologies.

Those devices have been embedded into the individual everyday practices, occupying personal spaces and making us share emotional and affective moments giving continuity to our anxiety and comprehension of the world.

The bodyspace relation and the technological artefacts (...) have been articulating the construction of the reality as a phenomenological experience. (shrink)

Although lie detection procedures have been fundamentally criticized since their inception at the beginning of the 20th century, they are still in use around the world. In addition, they have created some remarkable appeal in the context of counterterrorism policies. Thereby, the links between science and fiction in this topic are quite tight and by no means arbitrary: In the progressive narrative of the lie detection devices, there is a promise of changing society for the better, which is entangled (...) in a fictional narrative provided by many cinematic and literary examples. By drawing on the concept of “diegetic technologies” formulated by David Kirby, we want to highlight the role of science fictional narratives in the historical development and current application of lie detection procedures. We therefore aim to use this conceptual frame to analyze the role of prevention-oriented mind reading procedures, which are developed for or already used in the “war on terror” with reference to their fictional predecessors. One virulent factor has to be highlighted in this context: The fictional engagement with possible new lie detection practices is in itself creating a legitimating ground for future security technologies.

Computer technology and related Internet of things technology have penetrated into people’s daily life and industrial production; even in competitive sports training and competition, the Internet of things technology has also been a large number of applications. Traditional intelligent wearable devices are mainly used to calculate the steps of athletes or sports enthusiasts, corresponding physical data, and corresponding body indicators. The energy consumption calculated by these indexes is rough and the corresponding error is large. Based on this, this paper (...) will design a wearable device which can accurately calculate and monitor sports energy consumption based on relevant sensors and Internet of things technology. The corresponding core algorithm is the step counting algorithm, which can accurately calculate the relationship between human motion and the corresponding energy consumption and feed back to the intelligent device. In the experiment, the wearable device designed in this paper is compared with the traditional intelligent device. The experiment shows that the wearable device proposed in this paper is more accurate in energy consumption estimation than the traditional device, and its corresponding energy consumption is relatively small.

As clinical trials end, little is understood about how participants exiting from clinical trials approach decisions related to the removal or post-trial use of investigational brain implants, such as deep brain stimulation (DBS) devices. This empirical bioethics study examines how research participants experience the process of exit from research at the end of clinical trials of implanted neural devices. Using a modified grounded theory study design, we conducted semi-structured, in-depth interviews with 16 former research participants from clinical trials (...) of DBS and responsive neurostimulation (RNS). Open-ended questions elicited motivations for joining the trial, understanding of study procedures at the time of initial informed consent, the process of exiting from research, and decisions about device removal or post-trial device use. Thematic analysis identified categories related to: limited preparedness for the end of research participation, straightforwardness of decisions to explant or keep the device, reconciling with the end of research participation, reconciling post-trial expectations, and achieving a sense of closure after exit from research. A preliminary theoretical model describes contextual factors influencing the process and experience of exit from research. Experiences of clinical trial participants should guide research practices to enhance the ethical design and conduct of clinical trials in DBS and other brain devices. (shrink)

The current debate on closed-loop brain devices (CBDs) focuses on their use in a medical context; possible criminal justice applications have not received scholarly attention. Unlike in medicine, in criminal justice, CBDs might be offered on behalf of the State and for the purpose of protecting security, rather than realising healthcare aims. It would be possible to deploy CBDs in the rehabilitation of convicted offenders, similarly to the much-debated possibility of employing other brain interventions in this context. Although such (...) use of CBDs could in principle be consensual, there are significant differences between the choice faced by a criminal offender offered a CBD in the context of criminal justice, and that faced by a patient offered a CBD in an ordinary healthcare context. Employment of CBDs in criminal justice thus raises ethical and legal intricacies not raised by healthcare applications. This paper examines some of these issues under three heads: autonomy, human rights, and accountability. (shrink)

United States statistics continue to indicate that the human donor heart pool does not and will not meet the great demand for hearts. For those patients unresponsive to maximal medical therapy (approximately 60,000 patients per year), cardiac transplantation is currently their best hope for increased survival. To address the need for additional end-stage congestive heart failure (CHF) therapy options, three medical device manufacturers have developed implantable left ventricular assist devices (LVAD) which act as a pump for hemodynamic support of (...) the patient’s diseased heart. Although LVADs have been shown to improve patient disease state prior to organ transplantation. LVADs do nothing to increase the pool of human donor hearts, and they negatively impact the United Network for Organ Sharing (UNOS) waiting list by increasing the size of the waiting pool. This paper identifies and explores the ethical challenges presented by the use of LVADs as a bridging technology for heart transplant candidates. Although LVADs raise some ethical concerns, these concerns are outweighed by the proven medical efficacy of these devices. Thus, this technology should continue to be used and further developed.

Along with the growing utilization of the total artificial heart comes a new set of ethical issues that have, surprisingly, received little attention in the literature: How does one apply the criteria of irreversible cessation of circulatory function given that a TAH rarely stops functioning on its own?

And, On what ethical grounds can a (...) physician turn off a TAH in view of the fact that either the intent of such an action or the outcome is always, and necessarily, death? The aim of this article is not to answer these questions but to highlight why these questions must be explored in some depth given the growing use of TAH technology. (shrink)

Sensory substitution devices (SSDs) are most familiar from their use with subjects who are deficient in a target modality (e.g. congenitally blind subjects), but there is no doubt that the use and potential value of SSDs extend to persons without such deficits. Recent work by Amedi and his team (in particular Levy-Tzedek et al. 2012) has begun to explore this. Their idea is that SSDs may facilitate behavioural transference (BT) across sense modalities. In this case, a motor skill learned (...) through visual perception might be subsequently employed in response to auditory perception, using an SSD as a mediator. They infer from the existence of such BT that the learned skill is amodally represented. After a brief overview I identify ways to more fully test for BT within this experimental paradigm and argue that their conclusion about amodal representation is premature. Additionally, I argue that their preferred SSD (Eyemusic) is of limited value for the project. While my remarks are critical, my intention is to be constructive, particularly in light of the fact that Levy-Tzedek et al. (2012), is, I believe, the first output from Amedi's lab concerning this line of research. (shrink)

Socially assistive devices such as care robots or companions have been advocated as a promising tool in elderly care in Western healthcare systems. Ethical debates indicate various challenges. An important part of the ethical evaluation is to understand how users interact with these devices and how interaction influences users’ perceptions and their ability to express themselves. In this review, we report and critically appraise findings of non-comparative empirical studies with regard to these effects from an ethical perspective.Electronic databases (...) and other sources were queried using a comprehensive search strategy generating 9851 records. Studies were screened independently by two authors. Methodological quality of studies was assessed. For 22 reports on 21 datasets using a non-comparative design a narrative synthesis was performed.Data shows positive findings in regard to attitudes and emotional reactions of users. Varying perception of a social relation and social presence are the most commonly observed traits of interaction. Users struggle with understanding technical complexities while functionality of the devices is limited. This leads to a behavioral alignment of users towards the requirements of the devices to be able to make use of them.This evidence adds to three important ethical debates on the use of socially assistive devices in healthcare in regard to (1) reliability of existing empirical evidence to inform normative judgements, (2) ethical significance of the social presence of devices and (3) user autonomy in regard to behavioral alignment.

Phenomenology has a rich tradition of interpreting technology, medicine, and the life sciences. It has not yet had much to say about the medical devices which have always been central to bioethics. In this chapter, I outline what is meant by medical devices, and connect the sense of intention in made-object design with the notion of intentionality in phenomenology. I survey three basic ways of characterising medical devices grounded in the phenomenological literature: Albert Borgmann’s device paradigm, Don (...) Ihde’s human-machine relations, and Merleau-Ponty’s body-subject. Engaging with these approaches could help bring to analyses of medical devices the uniquely whole-of-context view of which phenomenology is capable, and better inform all stakeholders about their phenomenal consequences.
