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)

Los 18 trabajos recogidos en este volumen tienen como telón de fondo una preocupación por la racionalidad occidental. Mucho se ha hablado de su crisis o de su fracaso. De ello se ha ocupado durante décadas la Escuela de Francfort, en sus distintas reencarnaciones, y, más recientemente, el pensamiento posmoderno. Lo que este libro pretende es enfrentarnos a la crisis de la razón pero desde un ángulo insólito, desde el pensamiento judío. El judaísmo hizo su experiencia de la modernidad. Sintió (...) que no tenía sitio. Algunos de los autores aquí estudiados tuvieron que plantearse, en el momento de su madurez, que había que elegir entre ser moderno o marginarse. Durante siglos, la mayoría optó por lo primero, es decir, por la asimilación. Hasta que algunos plantearon y decidieron seguir siendo judíos sin renunciar a filosofar. Con ello el judaísmo se convierte en un lugar privilegiado para valorar el pulso de la razón occidental. El judaísmo era el límite de la Ilustración. Así lo planteaban los ilustrados y así lo vivieron durante mucho tiempo los propios pensadores judíos. Hasta que les dio por pensar por sí mismos. En este libro se reconstruyen algunos de esos memorables episodios. (shrink)

_The purpose _of this article is to find out whether philosophical and anthropological studies of human nature affect the legitimization of decisions about human life and death, using the example of a philosophical analysis of the problem of euthanasia. _Theoretical__ basis._ Philosophically and anthropologically based situational analysis in bioethics is chosen as the research methodology, which reveals the legitimation of euthanasia as a complex and highly responsible moral decision, which should be based on both the consideration of all the patient’s (...) special circumstances and the competent and adequate application of fundamental knowledge about the human being. _Originality._ From a philosophical point of view, it would be correct to legalize euthanasia, but under the condition of significantly limiting the cases of its application, clearly defining the conditions for its provision and strict control over its implementation. It is morally unacceptable to justify either murder or torture, so euthanasia appears as an attempt to avoid both at the same time. _Conclusions._ Specific solutions to practical problems often indicate the necessary direction for solving theoretical difficulties. Thus, making proper moral decisions about euthanasia requires reliance on fundamental knowledge about human beings, but at the same time it provides arguments "for" and "against" artificial termination of life. The basic principles of bioethics – autonomy, nonmaleficence, beneficence and respect for the dignity of human life – serve as criteria for making balanced ethical decisions both in theory and in practice. These principles should be complemented by a coherent ethical, legal and philosophical position on euthanasia, which is achieved through legitimation procedures. Decisive for making a decision on euthanasia should be the strong desire of the patient himself. (shrink)

In his thesis Para uma Teoria Geral dos Homomorfismos (1944), the Portuguese mathematician José Sebastião e Silva constructed an abstract or generalized Galois theory, that is intimately linked to F. Klein’s Erlangen Program and that foreshadows some notions and results of today’s model theory; an analogous theory was independently worked out by M. Krasner in 1938. In this paper, we present a version of the theory making use of tools which were not at Silva’s disposal. At the same time, we (...) tried to keep in mind, so much as possible, the gist of his standpoint. (shrink)

The restoration of "forgotten" names to the bosom of our culture is a natural and necessary accompaniment of the political freedom beginning to make its way in our country. Free and continuous creativity is being reunited with the reader, the listener, and the participant, who had been tragically alienated from it. Our half-knowledge, intellectual arbitrariness, and opportunism are becoming clearer, more acute, and more shameful. All this is an inevitable accompaniment of one of the most prestigious and, it would seem, (...) least labor consuming trends in contemporary publishing and journal policy. The publication of texts of Russian philosophers has marked journals as different in character and mission as Novyi mir, Voprosy filosofii, Literaturnaia ucheba, Druzhba narodov, Volga, and many others. In most cases they are more or less well known works reprinted from the YMCA Press, equipped with prefaces—some better, some worse—and devoid of any sort of real intellectual commentary. (shrink)

Paper-based privacy policies fail to resolve the new changes posed by electronic healthcare. Protecting patient privacy through electronic systems has become a serious concern and is the subject of several recent studies. The shift towards an electronic privacy policy introduces new ethical challenges that cannot be solved merely by technical measures. Structured Patient Privacy Policy (S3P) is a software tool assuming an automated electronic privacy policy in an electronic healthcare setting. It is designed to simulate different access levels and rights (...) of various professionals involved in healthcare in order to assess the emerging ethical problems. The authors discuss ethical issues concerning electronic patient privacy policies that have become apparent during the development and application of S3P. (shrink)

The ternary xV2O5–(40 − x)Li2O–60B2O3 glass system, where x = 1, 2, 3, 4 and 6 mol%, was prepared by normal quenching. Ultrasonic velocities and attenuation were measured at room temperature using a pulse-echo technique. Various parameters, such as elastic moduli, micro-hardness, Poisson's ratio and Debye temperature, were determined from the measured densities and velocities. The composition dependence of these parameters, in addition to the glass-transition temperature, suggested that vanadium ions were incorporated into these glasses as a network modifier, resulting (...) in the reconversion of BO4 tetrahedra to BO3 triangles by the breaking of B–O–B linkages and the formation of nonbridging oxygens (NBOs). The outcome was a reduction in network connectivity and rigidity with increasing V2O5 content. The results are explained quantitatively in terms of fractal bond connectivity, average atomic volume, network dimensionality, packing density, number of network bonds per unit volume, cross-link density and atomic ring size. The Makishima and Mackenzie model appears to be valid for the studied glasses when the fate of BO4 tetrahedra and creation of NBOs are taken into account. (shrink)

Upshot: According to Biology of Cognition and Language (Maturana’s approach) the immune system is not a cognitive system and defining of a cognitive paradigm is not what we understand as a Maturanian approach to immunology. The true cognitive actions in immunology are performed by immunologists acting as observers, not by body organs or systems. Stimuli and responses are not adequate concepts in the description of systems. As a closed network of cellular/molecular interactions, the immune system yields patterns of activity as (...) is transparent in robust conserved profiles of reactivity of natural immunoglobulins, as investigated by Nóbrega et al. and Cohen et al., which offer the opportunity to unravel its natural, spontaneous activity. Dietary materials, products of the commensal microbiome are the most abundant and common elements continuously incorporated to the network activity and, thus, also represent an important avenue of investigation.

The article analyzes the implementation of an online educational module and its impact on the organization of the classroom’s interaction order. The latter is institutionally constrained by the presence of a goal and the distribution of roles between teacher and students. The introduction of a digital learning platform adds a technological context to the institutional setting. The article considers technologies as possessing communicative affordances — opportunities for action made possible or delimited through their use. Technologies bring new interactive resources to (...) the process of ed­ucation and can affect the organization of the classroom’s interaction order. Using multimodal conversation analysis, we analyzed video recordings of the telemediated interaction of Russia-based students and teachers within a gamified online educational module. We investigate a case in which a student’s correct answer is nevertheless corrected by the teacher. We dem­onstrate that the teacher initiates the correction because they are guided by the ordering of the game elements within the interface. Based on a detailed analysis of the teacher’s mouse movement in relation to ongoing turns-at-talk, we show that this orientation is sustained by all participants. The work contributes to classroom interaction studies and affordance theory and develops the methodology of multimodal transcription for mediated contexts. The primary result of the study is an empirical demonstration that the relevance of technological affordances for interactants is situation­ally produced, and that this process is associated with the interweaving of the institutional and technical context of interaction. The conclusion discusses the relationship between affordances and institutional norms. (shrink)

BackgroundThe COVID-19 pandemic has created ethical challenges for intensive care unit (ICU) professionals, potentially causing moral distress. This study explored the levels and causes of moral distress and the ethical climate in Dutch ICUs during COVID-19.MethodsAn extended version of the Measurement of Moral Distress for Healthcare Professionals (MMD-HP) and Ethical Decision Making Climate Questionnaire (EDMCQ) were online distributed among all 84 ICUs. Moral distress scores in nurses and intensivists were compared with the historical control group one year before COVID-19. ResultsThree (...) hundred forty-five nurses (70.7%), 40 intensivists (8.2%), and 103 supporting staff (21.1%) completed the survey. Moral distress levels were higher for nurses than supporting staff. Moral distress levels in intensivists did not differ significantly from those of nurses and supporting staff. “Inadequate emotional support for patients and their families” was the highest-ranked cause of moral distress for all groups of professionals. Of all factors, all professions rated the ethical climate most positively regarding the culture of mutual respect, ethical awareness and support. “Culture of not avoiding end-of-life-decisions” and “Self-reflective and empowering leadership” received the lowest mean scores. Moral distress scores during COVID-19 were significantly lower for ICU nurses (p < 0.001) and intensivists (p < 0.05) compared to one year prior.ConclusionLevels and causes of moral distress vary between ICU professionals and differ from the historical control group. Targeted interventions that address moral distress during a crisis are desirable to improve the mental health and retention of ICU professionals and the quality of patient care. (shrink)

This study employed a scenario-based approach whereby participants were asked to choose which communication channel they prefer in certain situations. The first aim was to determine the effect of the topic of interactions and social ties on channel choice. The second aim was to examine the underlying mechanisms in the relation between interaction topic and social ties and channel choice. A questionnaire was administered among 238 participants, who were presented five communication scenarios with topics of low and high intimacy and (...) four social ties, ranging from weak to strong. Results revealed that preference for face-to-face communication was highest, followed by audio-only computer-mediated communication and text-based CMC. Preference for FtF communication was higher when people valued feeling co-present and decreased when people valued feeling anonymous. Our results showed that communication channel choice is strategic and the choice for FtF ommunication, audio-only and text-based CMC largely depends on controllability, anonymity and co-presence.

"The fixed person for fixed duties, who in older societies was such a godsend, in the future ill be a public danger." Twenty years ago, a single legal metaphor accurately captured the role that American society accorded to physicians. The physician was "c- tain of the ship." Physicians were in charge of the clinic, the Operating room, and the health care team, responsible - and held accountabl- for all that happened within the scope of their supervision. This grant of responsibility (...) carried with it a corresponding grant of authority; like the ship's captain, the physician was answerable to no one regarding the practice of his art. However compelling the metaphor, few would disagree that the mandate accorded to the medical profession by society is changing. As a result of pressures from a number of diverse directions - including technological advances, the development of new health professionals, changes in health care financing and delivery, the recent emphasis on consumer choice and patients' rights - what our society expects phy- cians to do and to be is different now. The purpose of this volume is to examine and evaluate the conceptual foundations and the moral imp- cations of that difference. Each of the twelve essays of this volume assesses the current and future validity of the "captain of the ship" metaphor from a different perspective. The essays are grouped into four sections. In Section I, Russell Maulitz explores the physician's role historically. (shrink)
