Most people agree that murder is wrong. Yet, within computer games virtual murder scarcely raises an eyebrow. In one respect this is hardly surprising, as no one is actually murdered within a computer game. A virtual murder, some might argue, is no more unethical than taking a pawn in a game of chess. However, if no actual children are abused in acts of virtual paedophilia (life-like simulations of the actual practice), does that mean we should disregard these (...) acts with the same abandon we do virtual murder? In this paper I shall outline several arguments which attempt to permit virtual murder, whilst prohibiting virtual paedophilia. (shrink)

Critics have argued that human-controlled avatar interactions fail to facilitate the kinds of expressivity and social understanding afforded by our physical bodies. We identify three claims meant to justify the supposed expressive limits of avatar interactions compared to our physical interactions. First, “The Limited Expressivity Claim”: avatars have a more limited expressive range than our physical bodies. Second, “The Inputted Expressivity Claim”: any expressive avatarial behaviour must be deliberately inputted by the user. Third, “The Decoding Claim”: users must infer or (...) figure out the expressive meaning of human-controlled avatars’ behaviour through cognitively onerous processes. With the aim of critically assessing all three claims, we analyze data collected through observations of and interviews with expert players of the avatar-based video game League of Legends. Focusing on Daniel Stern’s (2010) notion of vitality, we analyze the participants’ descriptions of seeing and interacting with other avatars during performance. Our analysis shows that the informants experience human-based avatarial interactions as qualitatively different than interactions with bots, that the informants see the movements of other players’ avatars as having different expressive styles, and that the informants actively use and manipulate this avatarial expressivity during performance. The results of our analysis, we argue, provide reasons for loosening or resisting the three claims concerning the limits of avatarial expressivity. (shrink)

This paper is an introduction to a virtual special issue of AI and Law exploring the legacy of the influential HYPO system of Rissland and Ashley. The papers included are: Arguments and cases: An inevitable intertwining, BankXX: Supporting legal arguments through heuristic retrieval, Modelling reasoning with precedents in a formal dialogue Game, A note on dimensions and factors, An empirical investigation of reasoning with legal cases through theory construction and application, Automatically classifying case texts and predicting outcomes, A factor-based (...) definition of precedential constraint and An improved factor based approach to precedential constraint. After describing HYPO, in this introduction to the special issue I look at various aspects of its influence on AI and Law: the developments led by Rissland at Amherst; the developments led by Ashley in Pittsburgh; the expression of these ideas in terms of rule based systems, and their subsequent formalisation; value based theories, which were inspired by a critique of HYPO; and contemporary approaches which revive the idea of dimensions.

Com este artigo, problematizou-se o potencial da formação continuada de professores por meio da educação a distância mediada pelo Moodle. Nessa perspectiva, pesquisou-se, principalmente, a integração hipermidiática das tecnologias nesse ambiente virtual de aprendizagem, no curso a distância de pós-graduação lato sensu em Mídias na Educação. Para isso, selecionou-se uma aula de uma disciplina desse curso oferecida no primeiro semestre de 2011 por uma universidade na qual um dos autores deste artigo trabalhou como professor-tutor. Assim, foi realizada uma investigação (...) com base na abordagem metodológica qualitativa através da observação participante, na qual se percebeu que a integração da hipermídia potencializa o diálogo-problematizador, a interatividade e o desenvolvimento da flexibilidade cognitiva nos professores-cursistas. Dessa forma, observou-se que a navegação em uma hipermídia educacional respeita o ritmo e as maneiras de aprendizagem de cada sujeito, uma vez que possibilita que os temas a serem estudados sejam acessados de forma não-linear, ou seja, de acordo com o interesse de cada aprendente e por meio de diferentes mídias. Isso viabilizou aos cursistas fazerem diversas associações entre diferentes conteúdos inter-relacionados, proporcionando assim uma ampliação da visão sobre os assuntos educacionais abordados na disciplina e, posteriormente, poderem aplicar esse conhecimento em novas situações de ensinoaprendizagem.

An exploration of modern society and the critical value of popular culture.

This work is developed to explore the form of mental health education, strengthen scientific educational ideas, and improve the effect of psychological therapy. Virtual reality technology is innovatively applied in adolescent mental health treatment and education. Based on this, the mental health treatment and system design based on virtual reality technology are discussed, and the feasibility of applying VR technology to adolescent mental health education is explored. Second, the research concept of adolescent mental health is discussed. Based on (...) the VR platform setup, questionnaire survey is implemented to analyze the factors influencing the mental health of primary and secondary school students in Xi’an, Shaanxi Province, and five factors are obtained. Based on this, the adolescent mental health treatment system based on VR is designed, and the effectiveness of the system is tested and evaluated. The results show that the integrated delay of the VR equipment used is 29 ms, which can effectively provide service. There are significant differences in mental health status among adolescents of different genders, different ages, only children and non-only children, parents’ accompaniment during growing up, and urban and rural adolescents. Finally, after 3 months of psychological treatment, the mental health score of the experimental group of teenagers is 50–55 points. However, the mental health scores of the control group remain at 56–65 points, indicating that the mental health treatment system designed in this work can effectively help the adolescents to improve their mental health, thus proving the effectiveness of the system. To sum up, this work provides scientific reference for adolescent mental health education in schools. Psychological treatment system can help teenagers improve their psychological problems and promote the development of mental health education. (shrink)

How promising is Bitcoin as a currency? This paper discusses four claims on the advantages of Bitcoin: a more stable currency than state-backed ones; a secure and efficient payment system; a credible alternative to the central management of money; and a better protection of transaction privacy. We discuss these arguments by relating them to their philosophical roots in libertarian and neoliberal theories, and assess whether Bitcoin can effectively meet these expectations. We conclude that despite its advocates’ enthusiasm, there are good (...) reasons to doubt that Bitcoin can fulfill its promises and act as a functioning currency, rather than as a mere speculative asset.

Las posibilidades educativas que ofrece la realidad virtual inmersiva (RVI) son actualmente incuestionables, si bien aún se cuenta con escasas propuestas que estén diseñadas expresamente por y para el aula. En esta contribución se presentan los primeros pasos de una interesante iniciativa diseñada por la Fundación Integra (Región de Murcia) entre las que se encuentra el desarrollo de un videojuego de RVI de temática histórica ambientado en el Teatro Romano de Cartagena y al que se juega con gafas Oculus (...) Rift o HTC VIVE. El videojuego ha sido diseñado a modo de serious game y se completa con una secuencia didáctica que permite su integración en el aula. A pesar de que aún no se ha realizado la fase de evaluación de los aprendizajes, la observación de los primeros prepilotajes del juego con estudiantes parecen mostrar su valor como elemento para el aprendizaje y favorecer un acercamiento motivador a la historia.

Internet technology has given birth to continuous changes in business model and format innovation. With increasingly critical consumers, blowout development model and format innovation, enterprises are increasingly aware of the importance of customer participation in service innovation. At the same time, the development of information technology provides convenient conditions for communication between enterprises and customers, and online virtual community also provides a platform for customers to participate in the process of enterprise service innovation in an instant. Based on the (...) theory of customer participation, knowledge transfer and service innovation performance, this paper explores the influence mechanism of customer participation in virtual community on service innovation performance, and analyzes the mediating role of knowledge transfer. Through the analysis of the results of the questionnaire, the relevant hypotheses are verified. The results show that customer participation in virtual community has a positive impact on service innovation performance. Customer participation helps enterprises obtain relevant knowledge such as customer needs and reduce barriers to knowledge sharing. In addition, enterprises will acquire customer knowledge about new products, which provides the possibility for the development of new products and services, thereby enhancing the enterprises’ service innovation performance. Knowledge transfer plays a part of mediating role between customer participation and service innovation performance. In the process of enterprises’ service innovation, customers mainly participate in the enterprise by means of knowledge transfer and help the enterprise improve service innovation performance.

Este artículo hace foco en el problema de la pérdida de la creencia del mundo, que Gilles Deleuze plantea en sus estudios sobre cine, a partir de uno de los temas ontológicos más perdurables en toda su obra: el par conceptual actual-virtual. Para ello, ponemos en relación la forma en la cual estos conceptos son expuestos y problematizados en Diferencia y repetición y cómo reaparecen en La imagen-movimiento (señalada por Deleuze como de carácter actual) y La imagen-tiempo (marcada por (...) su virtualidad). A partir de este prisma, presentamos una perspectiva en el debate de los estudios deleuzianos sobre la relación actual-virtual, que cuestiona tanto la prioridad virtual como la relación de mediación entre los planos (sea en su versión clásica o sofisticada), para volcarnos a un vínculo de coalescencia para cuya conceptualización aunamos los recursos teóricos del cristal del tiempo con los del envolvimiento de la Idea y la intensidad. En esa coalescencia es posible comprender de qué manera el plano virtual, lejos de emplazarnos fuera del mundo, nos permite según Deleuze volver a creer en él. (shrink)

This study examined the relationships between the role of the instructor and university students’ learning outcomes in cloud-based classrooms during the COVID-19 pandemic. The results of an online survey of 7,210 university students in mainland China revealed that the students’ perceived learning outcomes and learning satisfaction were positively related to instructor innovation and negatively related to instructor performance. Instructional support was positively related to the students’ perceived learning outcomes but not directly related to their learning satisfaction. The students’ academic self-efficacy (...) mediated the influence of instructional support and instructor innovation on their perceived learning outcomes and learning satisfaction. The results contribute to knowledge of the role instructors play in facilitating students’ learning outcomes in higher education and suggest ways to improve the learning environment and learning outcomes, especially in cloud-based virtual classrooms.

Despite the impressive amount of financial resources invested in carrying out large-scale brain simulations, it is controversial what the payoffs are of pursuing this project. The present paper argues that in some cases, from designing, building, and running a large-scale neural simulation, scientists acquire useful knowledge about the computational performance of the simulating system, rather than about the neurobiological system represented in the simulation. What this means, why it is not a trivial lesson, and how it advances the literature on (...) the epistemology of computer simulation are the three preoccupations addressed by the paper. (shrink)

PurposeThe purpose of this paper is to investigate how public policies may influence the way members of virtual communities linked with social movements perceive the legitimacy of their leaders and governance structures.Design/methodology/approachThis paper is based on qualitative research with three Brazilian environmental education virtual communities. It adopts an interpretive approach, grounding the analysis in institutional theory.FindingsThe paper shows that a public policy of funding the studied communities has reinforced the legitimacy of some leaders and legitimated more centralised decision‐making (...) structures. The influence of the funding has endured even after the end of the respective contracts.Research limitations/implicationsAlthough the paper is limited to three virtual communities in a very specific context, its conclusions may inform other studies on the institutional instruments governments may appropriate to influence the virtual interactions among members of social movements and civil society organisations and which impact their offline interactions as well.Practical implicationsThe paper calls attention to the need to discuss public policies with stakeholders, especially to permit social movements and civil society organisations to have a say in policies that may affect their social structures.Originality/valueThe paper contributes to understanding how public policies impact interactions in virtual environments and in a broader sense, and the relevance of considering the influence of institutions in online interactions.

Your classic Jaguar XK 120 stands useless by the roadside. Why? Because you gave priority to the admittedly gorgeous 6 cylinder straight six engine; because you privileged the highest value part. Rubber pipes perish, though, and now thanks to a leak in a cheap hose the head gasket has blown. You are stranded and facing a costly bill. More seriously, your mechanical gaffe is a sign of your misunderstanding of Deleuze. Like Sir William Lyons, he engineers systems where the concept (...) of priority must not be confused with independence, separateness, abstraction or ethical superiority. As a good engineer, Deleuze's constructions are holistic and opposed to abstract hierarchies: if a crucial small, actual part perishes in a particular practical situation where it has a role to play, then it does not matter how much virtual power you have in reserve. Your feet are still in a pool of hot water as you survey the wasted potential of actual motion and ideal expressions, hand made in Coventry. (shrink)

Research on the use of smartphone apps with the aim of developing self-regulated learning and increasing academic performance of university students in virtual mode, as a result of the COVID-19 pandemic, is recent and scarce. The present article shows the results of a study that analyzed the effect of using the 4Planning app with an intra-curricular approach on SRL and on the academic performance of 119 1st-year psychology students in virtual mode, at a Chilean university. The research was (...) conducted with quantitative methodology and a quasi-experimental design, with pre- and posttest measurements of an experimental group and comparisons with three control groups. The results show that students who used the app during 10 weeks of the first academic semester 2021: increased SRL self-report, increased academic self-efficacy, and obtained higher academic performance, compared to those who did not use it. The above occurs because the 4Planning app activates functions of the self-regulatory system of goal-directed behavior, which allows exercising the capacity of self-direction and self-influence on this type of behavior in the particular context of academic performance, which produces SRL. It is concluded that the 4Planning app is effective in developing self-regulation and improving the academic performance of 1st-year university students, in virtual learning mode. (shrink)

The efficient coding hypothesis posits that sensory systems are tuned to the regularities of their natural input. The statistics of natural image databases have been the topic of many studies, which have revealed biases in the distribution of orientations that are related to neural representations as well as behavior in psychophysical tasks. However, commonly used natural image databases contain images taken with a camera with a planar image sensor and limited field of view. Thus, these images do not incorporate the (...) physical properties of the visual system and its active use reflecting body and eye movements. Here, we investigate quantitatively, whether the active use of the visual system influences image statistics across the visual field by simulating visual behaviors in an avatar in a naturalistic virtual environment. Images with a field of view of 120° were generated during exploration of a virtual forest environment both for a human and cat avatar. The physical properties of the visual system were taken into account by projecting the images onto idealized retinas according to models of the eyes' geometrical optics. Crucially, different active gaze behaviors were simulated to obtain image ensembles that allow investigating the consequences of active visual behaviors on the statistics of the input to the visual system. In the central visual field, the statistics of the virtual images matched photographic images regarding their power spectra and a bias in edge orientations toward cardinal directions. At larger eccentricities, the cardinal bias was superimposed with a gradually increasing radial bias. The strength of this effect depends on the active visual behavior and the physical properties of the eye. There were also significant differences between the upper and lower visual field, which became stronger depending on how the environment was actively sampled. Taken together, the results show that quantitatively relating natural image statistics to neural representations and psychophysical behavior requires not only to take the structure of the environment into account, but also the physical properties of the visual system, and its active use in behavior.

This paper develops a taxonomy of kinds of actions that can be seen in group agency, human–machine interactions, and virtual realities. These kinds of actions are special in that they are not embodied in the ordinary sense. I begin by analysing the notion of embodiment into three separate assumptions that together comprise what I call the Embodiment View. Although this view may find support in paradigmatic cases of agency, I suggest that each of its assumptions can be relaxed. With (...) each assumption that is given up, a different kind of disembodied action becomes available. The taxonomy gives a systematic overview and suggests that disembodied actions have the same theoretical relevance as the actions of any ordinarily embodied human. (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)

Ways of communicating effectively in spoken English, using technology, in a virtual globalized context have received little attention from applied linguists. The role of language in synchronous computer-mediated discourse used in virtual teamwork is now emerging as a key area of research concern in business management and information technology disciplines. This article uses linguistic frameworks, most particularly critical discourse analysis and systemic functional linguistics, in particular appraisal analysis, to demonstrate how interpersonal meanings may create dominance, power and solidarity (...) within a sample of a virtual team management meetings. Focusing on one manager case study, we investigate how language is used, consciously or unconsciously, to dominate and close down discussion with his colleagues. We first present the key findings from a turn-taking analysis and then present, through the application of appraisal analysis, how this manager opens or contracts the space available for others to participate. By revealing how power and control unfold through this analysis, the findings may lead to an enhanced self-awareness among all members in virtual teams and reveal how language plays a crucial role in engaging members during a meeting, or in this case, disengaging them.

Designing a virtual environment within a digital game occupies a large part of the design procedure, requiring holistic attention and a broad arrangement of the game constituents. Considering other design disciplines, they occupy a unified design methodology; however, a comprehensive literature review reveals the lack of the intended design methodology in the digital game domain's virtual environment development, despite a currently proposed theoretical methodology trying to dissolve the issue. Hence, this research aims to determine the industry's requirements and (...) provide a set of assets included in current digital games as an initial step of providing such a design methodology for the domain. In this regard, the researchers reverse-engineered ten selected digital games, understanding the current condition of digital games via adopting the mentioned currently available design methodology. This dataset reveals a lack in the assets of the story layer in the recent digital games, despite their focus on being story-based. This dilemma leads to long text or speech conversations between game characters, disrupting the players while following the game. The current design focuses on environmental resources only, however, as a virtual landscape, the story needs to be reinforced to be a balanced and well-designed game. Hence, increasing the ratio of the assets in this layer will advance the games' interactivity. Also, as future work, this data set could pave the way for a digital game industry design tool regarding the virtual environment. (shrink)

The use of WhatsApp as a means of communication is widespread amongst today‘s youth, many of whom spend hours in virtual space, in particular during the evenings and nighttime in the privacy of their own homes.

The results evince that the youth related to the virtual space in very similar fashion to Buber‘s ―I-Thou‖ concept, the language they employed to describe what happened in it enabling an expansion of the conceptualization and research language to an ―I-Space-Thou‖ model.

Déjà vu is the striking sense that the present situation feels familiar, alongside the realization that it has to be new. According to the Gestalt familiarity hypothesis, déjà vu results when the configuration of elements within a scene maps onto a configuration previously seen, but the previous scene fails to come to mind. We examined this using virtual reality technology. When a new immersive VR scene resembled a previously-viewed scene in its configuration but people failed to recall the previously-viewed (...) scene, familiarity ratings and reports of déjà vu were indeed higher than for completely novel scenes. People also exhibited the contrasting sense of newness and of familiarity that is characteristic of déjà vu. Familiarity ratings and déjà vu reports among scenes recognized as new increased with increasing feature-match of a scene to one stored in memory, suggesting that feature-matching can produce familiarity and déjà vu when recall fails.

The phenomenon of knowledge withholding is a vital issue that undermines knowledge sharing and innovation, hinders the development of offline and online organizations. Clarifying the relationship between influencing factors and knowledge withholding is significant to improve the phenomenon of knowledge withholding in offline and online organizations. Few types of research focus on the online virtual academic community and integrate the three factors of knowledge, individual, and environment to research knowledge withholding. To solve the limitation, this research is based on (...) sociology and psychology-related theories. The two dimensions of enabling and inhibition are divided into factors affecting knowledge withholding. An attempt is made to explore the path between the three types of factors influencing knowledge, individual and environment, and knowledge withholding. This study collected data from 616 users in China’s virtual academic community. It used a structural equation model combined with a cross-layer connected neural network to conduct an empirical analysis on the proposed hypothesis. The results found that: in the virtual academic community, knowledge power in the enabling dimension is the main reason for users to form knowledge psychological ownership, which affects users’ knowledge withholding. However, the effect of professional commitment on users’ knowledge psychological ownership is not significant. After SEM-ANN model fitting, the combined inhibitory effect of community privacy protection and community reciprocity on user knowledge withholding in the inhibition dimension is significantly improved. This research has a specific guiding significance for enhancing the knowledge withholding phenomenon of the virtual academic community and creating an excellent academic exchange atmosphere.

ABSTRACTObjective: This study was designed to improve our understanding of prospective memory changes in ageing, and to identify the cognitive correlates of PM decline, using a virtual environment, to provide a more realistic assessment than traditional laboratory tasks.Design: Thirty-five young and 29 older individuals exposed to a virtual town were asked to recall three event-based intentions with a strong link between prospective and retrospective components, three event-based intentions with a weak link, and three time-based intentions. They also underwent (...) retrospective episodic memory, executive functions, binding in working memory, processing speed, and time estimation assessments.Results: Older individuals recalled fewer intentions than young adults. While age-related PM decline affected the recall of both prospective and retrospective components, the recall of the latter seemed more challenging for older individuals when the link was weak.

Theorizing further the design implications (...) integrating the overall approach including the evaluation experiment of three VH applications with the participation of young users and its semiotic analysis, we formulate design guidelines that can be applied also to other types of cultural heritage and art.

This paper is concerned with tracing how the notion of place circulates and is understood in literature from the 1980s and 1990s on computer-mediated information and communications technologies. It provides a brief account of at least two ways that the notion of place circulates in the discourse of the virtual. The first is that these technologies enable 'new' spaces that are claimed to be separate from conventional spaces and places. The second, contradictorily, is that the metaphor of place is (...) crucial as a setting for online social interaction. The paper also explores how we might understand the 'place' of place in the discourse of the virtual. It does this by drawing parallels from Jacques Derrida's critique of spatial metaphor in the text of philosophy with the use of place-based metaphors in the discourse of the virtual. This examination reveals that the reduction of place to metaphor in writing on virtual technologies belies the persistent and subtle force that is exerted by metaphor in general. Furthermore, the prevalence of place-based metaphors in the discourse of the virtual points to the ongoing importance of place as a wider concept. In particular, the notion of place is in fact fundamental to how virtual technologies are framed and understood. The paper concludes by sketching some of the possibilities and potential implications that emerge from this argument. (shrink)

ABSTRACT The current article deals with the correlation between virtual and physical reality as they concern the body. The thesis of this article is that the lived body transposed into virtual reality becomes a body without organs in Deleuze’s terms, i.e. the lived body, a sensitive field of sensorial events immersed in a lived space, becomes a virtual body made up of intensities, of pure forces or magnitudes within a vector space, thereby losing its affective qualities. Furthermore, (...) lived and virtual bodies build up a correlation bridged not by intentionality, as phenomenology would maintain, but by sensation. Virtuality is thus characterised by both the loss of corporeality and the simulation of the lifeworld. But how can the split between the real and the virtual body be bridged? On the one hand, in Deleuze’s conception of sensation, real and virtual collapse into one another so that the real world ‘resonates’ with its virtual double. On the other hand, Merleau-Ponty’s concept of form relates both realities in terms of a correlation of signification between the physical and the existential realms. With recourse to the notion of structure or form, I will argue that the phenomenal and the virtual do not represent different modes of being, but are bound by a correlation ruled by sensation as a system of intensive forces.

The distinction between the first-person perspective (1PP) and the third-person perspective (3PP) has been widely regarded as fundamental and rigid, and many researchers hold that genuine bodily illusions can only be experienced from the 1PP. We applied VR technology to investigate whether this mainstream view is correct. In our experiments, the participants were immersed in a VR environment in which they saw a life-sized virtual body either from the 1PP or from the 3PP. They either passively received tactile stimulations (...) and/or actively interacted with a virtual soccer ball. Our VR system created novel visuo-motor-tactile correlations between the real and the virtual world: when the participant interacted with a real plastic soccer ball, he/she would feel corresponding tactile sensations and see the avatar performing the exact same movements. We found that a clear sense of ownership over the avatar was induced not only in the 1PP condition but also in the Passive-3PP and the Active-3PP conditions. We also observed evidence suggesting that it is possible to experience one’s body-location, 1PP-location, as well as self-location, both from the 1PP and from the 3PP. Together, we demonstrate that there is in fact no fundamental gap between embodied 1PP and embodied 3PP in the virtual world. (shrink)
