Unilateral spatial neglect is a disorder characterized by the failure to report, respond to, or orient toward the contralateral side of space to a brain lesion. Current assessment methods often fail to discover milder forms, cannot differentiate between unilateral spatial neglect subtypes and lack ecological validity. There is also a need for treatment methods that target subtypes. Immersive virtual reality systems in combination with eye-tracking have the potential to overcome these shortcomings, by providing more naturalistic environments and tasks, with sensitive (...) and detailed measures. This systematic review examines the state of the art of research on these technologies as applied in the assessment and treatment of USN. As we found no studies that combined immersive VR and ET, we reviewed these approaches individually. The review of VR included seven articles, the ET review twelve. The reviews revealed promising results. All included studies found significant group-level differences for several USN measures. In addition, several studies found asymmetric behavior in VR and ET tasks for patients who did not show signs of USN in conventional tests. Particularly promising features were multitasking in complex VR environments and detailed eye-movement analysis. No VR and only a few ET studies attempted to differentiate USN subtypes, although the technologies appeared appropriate. One ET study grouped USN participants using individual heatmaps, and another differentiated between subtypes on drawing tasks. Regarding ecological validity, although no studies tested the prognostic validity of their assessment methods, VR and ET studies utilized naturalistic tasks and stimuli reflecting everyday situations. Technological characteristics, such as the field of view and refresh rate of the head-mounted displays, could be improved, though, to improve ecological validity. We found no studies that utilized VR or ET technologies for USN treatment up until the search date of the 26th of February 2020. In conclusion, VR-ET-based systems show great potential for USN assessment. VR-ET holds great promise for treatment, for example, by monitoring behavior and adapting and tailoring to the individual person’s needs and abilities. Future research should consider developing methods for individual subtypes and differential diagnostics to inform individual treatment programs. (shrink)

Wat is een weerbare democratie? Hoe gaan we om met krachten die zich niet aan de regels van onze rechtsstaat houden? 00Steeds meer politieke partijen stellen ongrondwettelijke maatregelen voor, radicale groeperingen trachten door terreur anderen hun wil op te leggen, buitenlandse regimes pogen in onze democratie te interveniëren en lidstaten van de EU nemen wetten aan die de democratie allesbehalve bevorderen. 'De strijd om de democratie' behandelt in het licht van deze ontwikkelingen het vraagstuk van de 'weerbare democratie'. In hoeverre (...) zijn ondemocratische maatregelen geoorloofd om de democratie te beschermen? In deze actuele bundel laten vooraanstaande denkers als Afshin Ellian, Bastiaan Rijpkema, Paul Cliteur, Gelijn Molier en Dirk Verhofstadt hun licht schijnen over deze meer dan urgente vraag.

Meditation refers to a family of self-regulation practices that focuses on training attention and awareness to foster psycho-emotional well-being and to develop specific capacities such as calmness, clarity, and concentration. We report a prospective convenience-controlled study in which we analyzed the effect of two components of Preksha Dhyāna – buzzing bee sound meditation and color meditation on healthy college students. Mahapran and leśya dhyāna are two Preksha Dhyāna practices that are based on sound and green color, respectively. The study population (...) represents a suitable target as college students experience different stress factors during the school year. This study measures the individual and combined effects of two techniques, on short-term memory, attention, and affect, in novice meditators. We used a battery of cognitive, performance, and compared results with baseline and control values. We found improved cognition, especially attention, short-term memory, and affect in terms of positivity and reduced negativity. Overall, the two techniques produced variable benefits and subjects showed improved scores over baseline for short-term memory, cognitive function, and overall wellbeing. Further studies are required to understand underlying mechanisms for the observed differences between the two techniques and to elucidate mechanisms underlying the more pronounced and global benefits observed with the combined techniques. These results underscore a need to examine individual components of meditation practices in order to individualize treatment approaches for attention disorders in young adults.Clinical Trail Registration:ClinicalTrials.gov Identifier: NCT03779269.

The central concern of this study is the basic question: what does it mean to travel? In order to understand this query, Hafizi places the discourse on travel within an economical framework and distinguishes between two interdependent forms: a restricted economy of travel and a general economy of travel.

Don DeLillo’s White Noise depicts a world of rapid techno-scientific and economical changes. Paul Virilio’s concepts of dromology and speed, as well as his notions of accident and technology, seem to be the most relevant in order to examine a novel centrally concerned with change, speed and technology. This article first offers an analysis of White Noise in the light of Virilio’s concept of integral accident in relation to the negative consequences brought about by industrial and technological progress. This is (...) followed by a discussion of the relevance to the novel of Virilio’s theories about architecture and space. Finally, Virilio’s theories about the replacement of conventional war with pure and info wars are discussed in the context of the central event of the novel. Reading the American writer through the lens of the French theorist can shed light on the enduring relevance of both. (shrink)

The relation between religion and politics is a legal-philosophical theme that has once again come to the foreground, due primarily to the terrorist attacks of 9/11 and the ensuing international debate on the nature of Islam. Yet every discussion of Islam encounters the resistance of political correctness, which exercises an enormous pressure on academic freedom, often resulting in self-censorship. Philosophy does not have as its primary goal the establishment of world peace. Instead, it begins by asking questions and by analyzing (...) reality, even if those questions and analyses turn out to be very painful to religious or political powers. Nietzsche.. (shrink)

This volume offers an up-to-date overview of the much-debated issue of how a democracy may defend itself against those who want to subvert it. The justifications, effectiveness and legal implications of militant democracy are discussed by addressing questions as: How can militant democracy measures such as party bans be justified? Why is it that some democracies ban antidemocratic parties? Does militant democracy succeed in combatting right-wing extremism? And is militant democracy evolving into an internationalized legal and political concept? Bringing together (...) experts and perspectives from political science, law and philosophy, this volume advances our understanding of the current threats to democracy, a political system once thought almost invincible. It is especially timely in the light of the rise of illiberal democracy in the EU, the increasingly authoritarian rule in Turkey, the steady shift to autocracy in Russia and the remarkable election of Trump in the US.

Hoe moet een democratie omgaan met antidemocraten, wat zijn de bedreigingen van de democratie, en hoe moeten die bedreigingen begrepen worden? Deze vragen staan centraal in het debat over weerbare democratie. Een discussie die aan actualiteit wint door de bedreigingen van religieus extremisme enerzijds en antirechtsstatelijke politieke partijen anderzijds. In dit artikel willen wij aantonen dat het debat over weerbare democratie verdiept kan worden door bestudering van het werk van Claude Lefort en Karl Popper. Het artikel is dan ook niet (...) zozeer een studie van het werk van Lefort en Popper als zodanig, maar in de eerste plaats een bijdrage aan de politiek-filosofische theorievorming over weerbare democratie. We bespreken de elementen in het werk van Lefort en Popper die voor de weerbare democratie relevant zijn. We betogen ten eerste dat zowel Lefort als Popper, om verschillende redenen, zich niet voetstoots laten uitleggen als weerbare democratiedenkers. Ten tweede, dat er, desondanks, in hun werk vruchtbare argumenten voor een weerbare democratie gevonden kunnen worden. En, ten derde, dat het denken van Lefort en Popper belangrijke lessen biedt die de theorie van weerbare democratie kunnen verdiepen. De belangrijkste les in het geval van Lefort is: aandacht voor democratie als samenlevingsvorm, en niet louter als institutie, en daarmee een beter begrip van hoe ons ‘democratisch-zijn’ kan uitmonden in democratische zelfvernietiging. Het denken van Popper kan daarentegen juist de ontsporingen binnen democratische instituties, of breder: het democratische debat, verhelderen. Tot slot probeert dit artikel ook een bescheiden aanzet te zijn tot een nadere bestudering van de samenhang in het werk van twee denkers die doorgaans in isolement bestudeerd worden. (shrink)

Jainism is essentially a spiritual philosophy having a strong focus on the ultimate purification of the soul (ātmā). A human being usually when fails to understand things, when sorrows attack, etc., then he attributes to memorize the deva (celestial being) to seek help. Man can be guided both correctly and incorrectly by the deva and can establish a new system in a society that can be both in a positive form and a negative form. Thus, this involvement of deva in (...) human life brings change in his culture, behavior, spirituality, etc. There is a lot of misunderstanding about deva. In Jain literature, it is mentioned as the difference between Arhat (Supreme Divine) and deva (celestial being), which will help the man to move in the right direction. In various positive and negative ways, a human is affected by deva, in the past and the present. (shrink)

We analyze von Weizsäcker’s view regarding the concept of information in physics. In his view, information arises from the reduction of properties of a physical object to their logical descriptive propositions. The smallest element of a lattice of propositions is an atom of information which is considered as the essence of every physical identity including position space. von Weizsäcker calls this element, “ur”. Moreover, Biological evolution is described in terms of enhancement of the variety of forms. Form could be also (...) reduced to descriptive logical propositions, thus to atoms of information. Therefore, information is the fundamental basis in von Weizsäcker’s plan for unifying all branches of Physics including Chemistry and Biology. Yet, there are inadequacies in his lines of reasoning, critically assessed in this paper. (shrink)

John Archibald Wheeler is one of the staunchest advocates of the idea that information is more fundamental than anything else in physics. In this paper, we examine the status of this idea summarized in Wheeler’s slogan ‘it from bit’ in the context of Bohmian Mechanics and spontaneous collapse models. We will argue that any question about the status of ‘it from bit’ crucially depends on the particular interpretation of these theories one favors.

We have provided a model-theoretic proof for the decidability of the additive structure of integers together with the function f mapping x to $$\lfloor \varphi x\rfloor $$ where $$\varphi $$ is the golden ratio.

In this study, we solve analytically the Schrödinger equation for a macroscopic quantum oscillator as a central system coupled to two environmental micro-oscillating particles. Then, the double-slit interference patterns are investigated in two limiting cases, considering the limits of uncertainty in the position probability distribution. Moreover, we analyze the interference patterns based on a recent proposal called stochastic electrodynamics with spin. Our results show that when the quantum character of the macro-system is decreased, the diffraction pattern becomes more similar to (...) a classical one. We also show that, depending on the size of the slits, the predictions of quantum approach could be apparently different with those of the aforementioned stochastic description. (shrink)

Background: Moral reasoning is a vital skill in the nursing profession. Teaching moral reasoning to students is necessary toward promoting nursing ethics. Objectives: The aim of this study was to compare the effectiveness of problem-based learning and lecture-based methods in ethics education in improving moral decision-making, moral reasoning, moral development, and practical reasoning among nursing students. Research design: This is a repeated measurement quasi-experimental study. Participants and research context: The participants were nursing students in a University of Medical Sciences in (...) west of Iran who were randomly assigned to the lecture-based or the problem-based learning groups. The subjects were provided nursing ethics education in four 2-h sessions. The educational content was similar, but the training methods were different. The subjects completed the Nursing Dilemma Test before, immediately after, and 1 month after the training. The data were analyzed and compared using the SPSS-16 software. Ethical considerations: The program was explained to the students, all of whom signed an informed consent form at the baseline. Findings: The two groups were similar in personal characteristics. A significant improvement was observed in the mean scores on moral development in the problem-based learning compared with the lecture-based group. Although the mean scores on moral reasoning improved in both the problem-based learning and the lecture-based groups immediately after the training and 1 month later, the change was significant only in the problem-based learning group. The mean scores on moral decision-making, practical considerations, and familiarity with dilemmas were relatively similar for the two groups. Conclusion: The use of the problem-based learning method in ethics education enhances moral development among nursing students. However, further studies are needed to determine whether such method improves moral decision-making, moral reasoning, practical considerations, and familiarity with the ethical issues among nursing students.

Background Since the beginning of the COVID-19 pandemic, different countries sought to manufacture and supply effective vaccines to control the disease and prevent and protect public health in society. The implementation of vaccination has created many ethical dilemmas for humans, which must be recognized and resolved. Therefore, the present study was conducted to analyze the ethical considerations in vaccination against COVID-19 from the perspective of service providers. Methods The present qualitative research was conducted in 2022 in the north of Iran. (...) The participants included 23 health workers with at least five years of work experience and members of the COVID-19 vaccination team. The data were initially collected through systematic semi-structured interviews, then snowball sampling and finally continued until data saturation. The next steps were transcription of interviews, identification of meaning units, coding, categorization based on similarity and symmetry, extraction of themes and the analysis of themes through content analysis. Results The analysis of participants’ experiences led to the extraction of five main categories of themes and fifteen sub-categories of the ethical considerations of COVID-19 vaccination. Safe and standard vaccine production, vaccine supply, fairness, respect for autonomy, and accountability were the main categories. The subcategories included compliance with scientific and ethical procedures, effectiveness and profitability of vaccine, absence of severe adverse effects, allocation of resources for vaccine supply, vaccine availability, diversity and comprehensiveness of alternative vaccines, vaccination prioritization, prioritization of the vulnerable populations of society, autonomy of patient (equal rights), autonomy of community, autonomy of service providers, reporting correct information, reporting vaccine side effects, public trust and acceptance. Conclusion The health system managers should be adequately prepared to solve the ethical problems posed by COVID-19 vaccination. Therefore, it is recommended to avoid haste in vaccination and pay more attention to vaccination safety standards, provide sufficient resources for a comprehensive vaccine supply, pay close attention to collective interests versus individual interests, and meet community needs.

Using devices such as unified power quality conditioners in distribution networks seems essential for higher electricity quality. Moreover, distribution network reconfiguration is a suitable model for improving network characteristics, including loss reduction and voltage increase for distribution networks, and is widely used in this era. Here, the study discusses the rechanging of distribution networks for UPQC via proposing an appropriate model for it. In addition to the optimum structure of distribution networks, the most appropriate branch where UPQC must be located (...) and the most appropriate reactive power size with which series and shunt filters must be injected into the grid are determined. The simulations have been applied on two 69- and 84-standard-bus networks. The results of the simulations indicate much power loss reduction and much voltage increase in the presence of UPQC compensators. (shrink)

According to Zeilinger’s information interpretation of quantum mechanics ‘the distinction between reality and our knowledge of reality, between reality and information, cannot be made. They are in a deep sense indistinguishable’. This is what we call Zeilinger’s thesis. This thesis has been criticized as a lapse into ‘informational immaterialism’ and amounting to nothing more than a tautology. However, we will argue that this criticism is based on a pre-Kantian view of reality, namely metaphysical realism which could be questioned on the (...) basis of Putnam’s arguments. Furthermore, it will be argued that to understand Zeilinger’s thesis one should abandon the pre-Kantian perspective of metaphysical realism and adopt a post-Kantian perspective on the relationship between the mind and the world.
