We humans often respond effectively when faced with novel circumstances. This is because we are able to predict how particular alterations to the world will play out. Philosophers, psychologists, and computational modelers have long favored an account of this process that takes its inspiration from the truth-preserving powers of formal deduction techniques. There is, however, an alternative hypothesis that is better able to account for the human capacity to predict the consequences worldly alterations. This alternative takes its inspiration from the (...) powers of truth preservation exhibited by scale models and leads to a determinate computational solution to the frame problem. (shrink)

Previous work in Game Studies has centered on several loci of investigation in seeking to understand virtual gameworlds. First, researchers have scrutinized the concept of the virtual world itself and how it relates to the idea of “the magic circle”. Second, the field has outlined various forms of experienced “presence”. Third, scholarship has noted that the boundaries between the world of everyday life and virtual worlds are porous, and that this fosters a multiplicity of identities as players (...) identify both with themselves-offline and themselves-in-game. Despite widespread agreement that these topics are targets for research, so far those working on these topics do not have mutually agreed-upon framework. Here we draw upon the work of Alfred Schutz to take up this call. We provide a phenomenological framework which can be used to describe the phenomena of interest to Game Studies, as well as open new avenues of inquiry, in a way acceptable and useful to all. This helps to distinguish the core of the field from the supplemental theoretical and critical commitments which characterize diverse approaches within the field. (shrink)

The questions of this article are: what can we learn from deliberative democratic theory, its critics, the practices of local deliberative communities, the needs of potential participants, and the experiences of virtual communities that would be useful in designing a technology-facilitated institution for global civil society that is deliberative and democratic in its values? And what is the appropriate design of such an online institution so that it will be attentive to the undemocratic forces enabled by power inequalities that (...) can emerge in discursive communities? I answer these questions with an institutional innovation that meets a need of global civil society and that is responsive to critics of deliberative democratic theory and attentive to the particular agents engaged in women's human rights activism.

O'Regan & Noë run into some difficulty in trying to reconcile their “seeing as acting” proposal with the perception and action account of the functions of the two streams of visual projections in the primate cerebral cortex. I suggest that part of the problem is their reluctance to acknowledge that the mechanisms in the ventral stream may play a more critical role in visual awareness and qualia than mechanisms in the dorsal stream.

The term "viewing stones" is primarily associated with two traditions of stone appreciation: Chinese Gongshi and Japanese suiseki. Today, viewing-stone associations around the world take inspiration from these traditions and are creating new ways of displaying stones. Petraphiles, whether ancient or contemporary, are often drawn to express their appreciation of favored stones in writing.The Petraphiles represented in this virtual exhibition are diverse in their expressions of geo-affection.

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)

A variety of evidence demonstrates that memory is a reconstructive process prone to errors and distortions. However, the complex relationship between memory encoding, strength of memory reactivation, and the likelihood of reporting true or false memories has yet to be ascertained. We address this issue in a setting that mimics a real-life experience: We asked participants to take a virtual museum tour in which they freely explored artworks included in the exhibit, while we measured the participants’ spontaneous viewing time (...) of each explored artwork. In a following memory reactivation phase, participants were presented again with explored artworks, followed by novel artworks not belonging to the same exhibit. For each of these objects, participants provided a reliving rating that indexed the strength of memory reactivation. In the final memory recognition phase, participants underwent an old/new memory task, involving reactivated vs. baseline targets, and activated and baseline lures. The results showed that those targets that were spontaneously viewed for a longer amount of time were more frequently correctly recognized. This pattern was particularly true for reactivated targets associated with greater memory strength. Paradoxically, however, lures that were presented after targets associated with higher reliving ratings in the reactivation phase were more often erroneously recognized as artworks encountered during the tour. This latter finding indicates that memory intrusions, irrespective of the viewing time, are more likely to take place and be incorporated into true memories when the strength of target memory is higher.

ABSTRCTIn recent times, Information and Communication Technology (ICT) hasbeen developed and widely spread around world. ICT is used in various sectorsand considered a basis in the emergence of some important technologies such asvirtual reality technology. Virtual Reality (VR) is a special technology as anadvanced technology connected to several fields, e.g. training, learning, science,engineering, medicine, military, etc. VR has great potentials which enabled toperform several phenomena and experiments. Hence, several scenarios havebecome available. The purpose of this study is to shed (...) light on virtual realitytechnology and list a glimpse of common publications and studies involved. (shrink)

This article considers two related and fundamental issues about morality in a virtual world. The first is whether the anonymity that is a feature of virtual worlds can shed light upon whether people are moral when they can act with impunity. The second issue is whether there are any moral obligations in a virtual world and if so what they might be. -/- Our reasons for being good are fundamental to understanding what it is that makes us (...) moral or indeed whether any of us truly are moral. Plato grapples with this problem in book two of The Republic where Socrates is challenged by his brothers Adeimantus and Glaucon. They argue that people are moral only because of the costs to them of being immoral; the external constraints of morality. -/- Glaucon asks us to imagine a magical ring that enables its wearers to become invisible and capable of acting anonymously. The ring is in some respects analogous to the possibilities created by online virtual worlds such as Second Life, so the dialogue is our entry point into considering morality within these worlds. These worlds are three dimensional user created environments where people control avatars and live virtual lives. As well as being an important social phenomenon, virtual worlds and what people chose to do in them can shed light on what people will do when they can act without fear of normal sanction. -/- This paper begins by explaining the traditional challenge to morality posed by Plato, relating this to conduct in virtual worlds. Then the paper will consider the following skeptical objection. A precondition of all moral requirements is the ability to act. There are no moral requirements in virtual worlds because they are virtual and it is impossible to act in a virtual world. Because avatars do not have real bodies and the persons controlling avatars are not truly embodied, it is impossible for people to truly act in a virtual world. We will show that it is possible to perform some actions and suggest a number of moral requirements that might plausibly be thought to result. Because avatars cannot feel physical pain or pleasure these moral requirements are interestingly different from those of real life. Hume’s arguments for why we should be moral apply to virtual worlds and we conclude by considering how this explains why morality exists in these environments. (shrink)

This paper presents and discusses the website. Under the title “The Virtual Laboratory: Essays and Resources on the Experimentalization of Life” it gives access to a massive collection of texts and images concerning the experimental life sciences of the 19th and early 20th century. The main focus is on physiology and psychology. Plant breeding is an additional theme. As of now, the Virtual Laboratory gives access to some 12,000 digital items, i.e. historical text books, journal articles, manuscripts, trade (...) catalogs, photos, films, audio files, etc. At the same time, the Virtual Laboratory is a platform for historians of science to publish and discuss their research on the experimentalization of life. Topics range from the history of precision time measurements in the physiological lab to the historical epistemology of hearing and the role of the Axolotl as an experimental animal in zoology. By way of a guided tour through the Virtual Laboratory, the paper describes the kind of epistemic space that was created. It argues that open access to historical sources as well as tight connections between historical research papers and their raw data, e.g. manuscript sources, profoundly change what used to be called the Archive. Today’s historians of science have started to work within a space that is widely distributed and extremely flexible with respect to its internal connections. It is a space that turns the Archive into an authentic laboratory for the science historian. (shrink)

In his “A New Program for Philosophy of Science?”, Ronald Giere expresses qualms regarding the critical and political projects I advocate for philosophy of science—that the critical project assumes an underdetermination absent from actual science, and the political project takes us outside the professional pursuit of philosophy of science. In reply I contend that the underdetermination the critical project assumes does occur in actual science, and I provide a variety of examples to support this. And I contend that the political (...) project requires no more than what other academic fields even in science studies are already providing. (shrink)

Therapeutic strategies capable of inducing and enhancing prosthesis embodiment are a key point for better adaptation to and acceptance of prosthetic limbs. In this study, we developed a training protocol using an EMG-based human-machine interface that was applied in the preprosthetic rehabilitation phase of people with amputation. This is a case series with the objective of evaluating the induction and enhancement of the embodiment of a virtual prosthesis. Six men and a woman with unilateral transfemoral traumatic amputation without previous (...) use of prostheses participated in the study. Participants performed a training protocol with the EMG-based HMI, composed of six sessions held twice a week, each lasting 30 mins. This system consisted of myoelectric control of the movements of a virtual prosthesis immersed in a 3D virtual environment. Additionally, vibrotactile stimuli were provided on the participant’s back corresponding to the movements performed. Embodiment was investigated from the following set of measurements: skin conductance response, crossmodal congruency effect, ability to control the virtual prosthesis, and reports before and after the training. The increase in the skin conductance response in conditions where the virtual prosthesis was threatened, recalibration of the peripersonal space perception identified by the crossmodal congruency effect, ability to control the virtual prosthesis, and participant reports consistently showed the induction and enhancement of virtual prosthesis embodiment. Therefore, this protocol using EMG-based HMI was shown to be a viable option to achieve and enhance the embodiment of a virtual prosthetic limb. (shrink)

PurposeThe purpose of this paper is to outline a case where people's intuitions regarding the ethical status of an action performed in a massively multiplayer online role‐playing game are divided, and provide an argument to resolve this division.Design/methodology/approachThis paper takes a philosophical approach, from the analytical tradition. It details the main arguments for each side and provides counter‐arguments in order to indicate the salient points.FindingsThe paper argues that, of the three arguments for the morality of particular virtual action outlined (...) in this paper, none are satisfactory. An argument for the immorality of the action in questions based upon the fairness/sportsmanship distinction is offered.Originality/valueThe development of case‐based ethical studies, which draw upon current and controversial events within popular virtual environments, are useful in the construction of a deeper understanding of moral action within such spaces.

This article shows the organization of distance learning, particularly the idea of b-learning, combining the accomplishment of classes carried on in the traditional way and via computers. The authors present learning activities related to complementary education herein. Some of these course types may be successfully adapted to an e-learning background. The models and structure of the university virtual environment for distance learning are described. These illustrate a new approach to creating a virtual space for medical and technical studies (...) where e-learning courses are created to be used for distance education, which allows students to be taught more effectively. The projected virtual courses for different groups of students ensure individualization of students’ work, which could be a relevant element for creating the shortest path of development of professional competencies. This paper further includes a brief overview of technologies used to build interactive elements into learning mate- rials. The authors present the use of interactive elements in medical education based on examples of certain selected games and animations. (shrink)

The research explores a novel phenomenon in which information and communication technology (ICT), which is originally designed for knowledge transferring, may result in employees’ knowledge hiding due to increasing use intensity. Specifically, drawing upon the appraisal theory of empathy, we develop a moderated mediation model of empathy linking ICT use intensity and knowledge hiding. The hypothesized model is tested by conducting a scenario-based experimental study (Study 1, N = 194) and a multi-wave field study (Study 2, N = 350). Results (...) show that ICT use intensity is positively related to employees’ knowledge hiding through the mediating role of their empathy. Moreover, competitive goal interdependence strengthens the negative relationship between ICT use intensity and employees’ empathy, and the indirect positive effect between ICT use intensity and employees’ knowledge hiding. Overall, the research answers the questions of how and when ICT use intensity may influence employees’ knowledge hiding. Finally, the theoretical and practical implications of the research findings are discussed. (shrink)

The conscious experiences we have during sleep have the potential to improve our empathetic response to those who experience delusions and psychosis by supplying a virtual reality simulation of mental illness. Empathy for those with mental illness is lacking and there has been little improvement in the last decades despite efforts made to increase awareness. Our lack of empathy, in this case, may be due to an inability to accurately mentally simulate what it’s like to have a particular cognitive (...) disorder. Dreaming can help mitigate these deficits by placing the dreamer directly into a realistic virtual simulation and thus increase their capacity for empathy. Increasing empathy would go some way towards reducing the stigma and discrimination faced by people in this group. Recent work suggests that virtual reality can increase empathy towards a variety of marginalised groups, however, this technology is limited in its ability to simulate mental illnesses such as delusions. Dreams, however, are at times virtual reality delusion simulators. They can replicate, to a reasonable degree, delusions and psychosis, and through these experiences, we can learn ‘what it’s like’ to have these conditions. It is essential that we recognise these experiences for what they are, attempt to remember and reflect on them. Instead of disregarding dreams due to their unusualness and bizarreness, we can learn from these experiences and expand our understanding of the human condition and its many forms. (shrink)

Reflections on digital mourning in the wake of the mass shooting at the Pulse nightclub in Orlando 2016.

This article discusses the transformation of a tiny three-dimensional artwork created in the metaverse that takes its inspiration from Jorge Luis Borges’s story of ‘the Aleph’ – a tale that revolves around a minute artefact that is ‘one of the points in space that contains all other points’. The visualization of a concept as complex as ‘the Aleph’ led the author of the project through a process that started from Cartesian precepts, from where it transformed itself into an investigation of (...) ‘code’ as a basal, life-giving presence that is abstract, enigmatic and hermetic in its essence. This correlation between ‘code’ and the magical nature of ‘the Aleph’ has led to further considerations regarding the significance of such a marvellous object within virtual worlds. Accordingly, this text will conclude with the description of an intriguing, novel usage for ‘the Aleph’ that materializes as a time machine for virtual-world avatars. (shrink)

The use of head-mounted displays (HMD) for virtual reality (VR) application-based purposes including therapy, rehabilitation, and training is increasing. Despite advancements in VR technologies, many users still experience sickness symptoms. VR sickness may be influenced by technological differences within HMDs such as resolution and refresh rate, however, VR content also plays a significant role. The primary objective of this systematic review and meta-analysis was to examine the literature on HMDs that report Simulator Sickness Questionnaire (SSQ) scores to determine the (...) impact of content. User factors associated with VR sickness were also examined. A systematic search was conducted according to PRISMA guidelines. Fifty-five articles met inclusion criteria, representing 3,016 participants (mean age range 19.5-80; 41% female). Findings show gaming content recorded the highest total SSQ mean 34.26 (95%CI 29.57-38.95). VR sickness profiles were also influenced by visual stimulation, locomotion and exposure times. Older samples (mean age ≥35 years) scored significantly lower total SSQ means than younger samples, however, these findings are based on a small evidence base as a limited number of studies included older users. No sex differences were found. Across all types of content, the pooled total SSQ mean was relatively high 28.00 (95%CI 24.66-31.35) compared with recommended SSQ cut-off scores. These findings are of relevance for informing future research and the application of VR in different contexts. (shrink)

Major events such as the COVID-19 pandemic, Olympic Games, and G20 Summit bring about supplier disruption risks and challenges to supply chain management. To help deal with these risks, a virtual dual-sourcing production-inventory system can be deployed. In this paper, we study such a system which consists of a raw material supplier, a manufacturer, and a virtual dual-sourcing contingency supplier. The manufacturer needs to determine the production, procurement, and inventory plan of raw materials. When its supplier is interrupted, (...) the manufacturer may need to adjust the production and inventory plan and work with the contingency supplier. We develop a system dynamics method to simulate the operations in this production-inventory system to identify the approximately optimal order-up-to-level inventory policies. We find that the virtual dual production-inventory strategy can be the optimal contingency policy to deal with supplier dynamic disruption risks. Furthermore, for disruption risk with low frequency and long duration, the manufacturer should increase the safety inventory level before the disruption. Otherwise, it should increase the safety inventory level in every cycle. (shrink)

The emergence of the hominids, more than five million years ago, marked the start of the human odyssey through space and time. This book deals with the last stage of this fascinating journey: the exploration of cyberspace and cybertime. Through the rapid global implementation of information and communication technologies, a new realm for human experience and imagination has been disclosed. Reversely, these postgeographical and posthistorical technologies have started to colonize our bodies and minds. Taking Homer's Odyssey and Kubrick's 2001: A (...) Space Odyssey as his starting point, the author investigates the 'informatization of the worldview', focusing on its implications for our culture-arts, religion, and science-and, ultimately, our form of life. Moving across a wide range of disciplines, varying from philosophical anthropology and palaeontology to information theory, and from astrophysics to literary, film and new media studies, the author discusses our 'cyberspace odyssey' from a reflective position beyond euphoria and nostalgia. His analysis is as profound as nuanced and deals with issues that will be high on the agenda for many decades to come. In 2003 a Dutch Edition of Cyberspace Odyssey received the Socrates Prize for the best philosophy book published in Dutch. (shrink)

At some distance from a high-rate source in an elastic half-space, the dominant wave motion at the free surface is a Rayleigh surface wave. The calculation of surface waves generated by a concentrated force in a half-space is a basic problem in elastodynamics. By straightforward manipulations, the result can be used to obtain surface waves for other kinds of wave-generating body-force arrangements. For example, appropriate combinations of double-forces (or dipoles) can be used to represent the surface loading due to laser (...) irradiation, or due to acoustic emission from the opening of a sub-surface crack or from sliding over a fault surface. The surface wave motion is usually obtained by the application of integral transform techniques and the subsequent extraction of the surface waves as the contributions from poles in the integral for the inverse transform. In this paper, we use a much simpler approach based on the elastodynamic reciprocity theorem. We consider a transversely isotropic solid whose axis of symmetry is normal to the surface of the half-space. Surface wave pulses generated by a single force, by irradiation from a laser source, and by opening of a crack, have been determined. (shrink)

The purpose of the article is distinguishing between "internal" and "external" public human through comprehending the phenomenon of Self in its virtual-digital essence as a popular demonstrative-project space "BETWEEN" aggression and harmony. Theoretical basis of the work is based on the study of the phenomenon of modern human aggression in the virtual-digital space and the "project space" of the living environment through understanding the nature of the human "I". The penetration limits of the Self of the public human (...) into the "project space" are comprehended and the nature of the self-realization and self-search models of human through the "transcendent ego" is revealed. Originality is demonstrated through comprehending the Self phenomenon of the public human, which forms new anthropological research direction and represents a conceptual paradigm of relationship of "human I – publicity – human We – the living space of the Other". Conclusions. The Self of the public human as the space "BETWEEN" does not completely "dissolve" in a separate ontological basis, but is the basis for the formation of his/her "I", while only participation in the existence of others reveals the meaning of his/her own existence. Such interaction requires significant human efforts – skills and competencies of public communication, which are able to create a successful self-identification of a public human without aggression and conflict.
