A common understanding of quantum mechanics (QM) among students and practical users is often plagued by a number of “myths”, that is, widely accepted claims on which there is not really a general consensus among experts in foundations of QM. These myths include wave-particle duality, time-energy uncertainty relation, fundamental randomness, the absence of measurement-independent reality, locality of QM, nonlocality of QM, the existence of well-defined relativistic QM, the claims that quantum field theory (QFT) solves the problems of relativistic QM or (...) that QFT is a theory of particles, as well as myths on black-hole entropy. The fact is that the existence of various theoretical and interpretational ambiguities underlying these myths does not yet allow us to accept them as proven facts. I review the main arguments and counterarguments lying behind these myths and conclude that QM is still a not-yet-completely-understood theory open to further fundamental research. (shrink)

Spontaneous intrusive recollections are known to follow emotional events in clinical and non-clinical populations. Previous work in our lab has found that women report more SIRs than men after exposure to emotional films, and that this effect is driven entirely by women in the luteal phase of the menstrual cycle. To replicate and extend this finding, participants viewed emotional films, provided saliva samples for sex hormone concentration analysis, and estimated SIR frequency following film viewing. Women in the luteal phase reported (...) significantly more SIRs than did women in the follicular phase, and SIR frequency significantly correlated with salivary progesterone levels. The results are consistent with an emerging pattern in the literature suggesting that menstrual cycle position of female participants can potently influence findings in numerous cognitive domains. The potential implications of these results for disorders characterized by intrusions, such as post-traumatic stress disorder, are also discussed. (shrink)

Recently, swimming-style colour synaesthesia was introduced as a new form of synaesthesia. A synaesthetic Stroop test was used to establish its genuineness. Since Stroop interference can occur for any type of overlearned association, in the present study we used a modified Stroop test and psychophysiological synaesthetic conditioning to further establish the genuineness of this form of synaesthesia. We compared the performance of a swimming-style colour synaesthete and a control who was trained on swimming-style colour associations. Our results showed that behavioural (...) aspects of swimming-style colour synaesthesia can be mimicked in a trained control. Importantly, however, our results showed a psychophysiological conditioning effect for the synaesthete only. We discuss the theoretical relevance of swimming-style colour synaesthesia according to different models of synaesthesia. We conclude that swimming-style colour synaesthesia is a genuine form of synaesthesia, can be mimicked behaviourally in non-synaesthetes, and is best explained by a re-entrant feedback model.

Statistical physics cannot explain why a thermodynamic arrow of time exists, unless one postulates very special and unnatural initial conditions. Yet, we argue that statistical physics can explain why the thermodynamic arrow of time is universal, i.e., why the arrow points in the same direction everywhere. Namely, if two subsystems have opposite arrow-directions at a particular time, the interaction between them makes the configuration statistically unstable and causes a decay towards a system with a universal direction of the arrow of (...) time. We present general qualitative arguments for that claim and support them by a detailed analysis of a toy model based on the baker’s map. (shrink)

Deep-rooted political turbulence, along with the present hybrid regime, have resulted in an undesirable social, economic and political milieu in Serbia. Such an atmosphere is a fertile ground for a grey economy, corruption, nepotism and restrictions to media freedoms. These?unconventional? means of social functioning, have caused a decline in trust towards state institutions and proportionally, increase of citizen participation in non-institutional models of engagement. The aim of this paper is to analyse one such model of non-institutional engagement: the local activist (...) group Za nas Kej, operating in the area Savski blokovi in New Belgrade. The authors analysed local residents? perception of the activist group Za nas Kej in comparison to the group?s narratives and actions. By using a grounded theory approach authors explained the role of groups such as Za Nas Kej in the development of participatory and deliberative democracy within the local community. Our data indicates that Za nas kej, despite its local character, does not have a strong foothold in the community, and thus receives only passive support. Citizens perceive Za nas kej as mediator between local institutions and residents of the Sava apartment blocks. Despite the failure to mobilise a wider group of citizens for their cause, this activist group continues to be a relevant actor within the local community. (shrink)

Times of uncertainty and fear were brought on by Covid-19. The ongoing pandemic is a fruitful ground for fake news, as citizens try to find explanations that fit into their worldviews. This process polarizes society and creates echo chambers amplified by recommender systems. Our main goal is to detect anti-vaxxer echo chambers in Serbia by analyzing online reactions to the recent detention of prominent anti-vaxxer Dr. Jovana Stojkovic. A content analysis of online comments is deployed in anti-regime left-leaning, anti-regime right-leaning, (...) and pro-government media to explore attitudes towards a vaccination conspiracy theory, police action towards anti-vaxxers, and the government crisis response team. We clearly identify the anti-vaccine echo chamber among commentators of anti-regime right-leaning media (YouTube podcasts). Additionally, we describe attitudes expressed around issues related to vaccination. Limitations and implications for future research are discussed. (shrink)

Spontaneous intrusive recollections follow traumatic events in clinical and non-clinical populations. To determine whether any relationship exists between SIRs and enhanced memory for emotional events, participants viewed emotional or neutral films, had their memory for the films tested two days later, and estimated the number of SIRs they experienced for each film. SIR frequency related positively to memory strength, an effect more pronounced in the emotional condition. These findings represent the first demonstration of a relationship between SIRs occurring after an (...) emotional experience and subsequent memory strength for that experience. The results are consistent with the possibility that emotional arousal leads both to elevated SIR frequency and better memory, and that the covert rehearsal associated with SIRs enhances memory for emotional relative to neutral stimuli. Additional evidence of menstrual cycle influences on SIR incidence in female participants appears to merit consideration in future work. (shrink)

Although Lermontov is traditionally viewed as Russia's “second greatest poet,” the bard of Russia's beauty and the critic of Russia's “superfluous men,” the philosophical content of his poetry and prose remains relatively unexamined. The article considers Lermontov's themes of the rebellious angel, freedom, and fate, and argues that although these themes were a product of his time, they are still relevant today.

Even though the Bohmian trajectories given by integral curves of the conserved Klein-Gordon current may involve motions backwards in time, the natural relativistic probability density of particle positions is well-defined. The Bohmian theory predicts subtle deviations from the statistical predictions of more conventional formulations of quantum theory, but it seems that no present experiment rules this theory out. The generalization to the case of many particles or strings is straightforward, provided that a preferred foliation of spacetime is given.

Our main goal is to describe the structure of engaged acts and compassion and their constitutive interrelation to explicate the key role of engaged and compassionate acts for group constitution. In the first part of the paper, we formulate our guiding idea: the key to understanding compassion lies in understanding engagement and vice versa. We then consider the problematic nature of engaged acts: On the one hand, they do not meet the conditions to be attributed to the plural subject; on (...) the other hand, they cannot be understood without presupposing the plural subject. To understand this, we rely primarily on Helm’s theory of emotions and the classical phenomenological analyses of the constitution of the plural subject, but we also point out the limitations of the latter. In the last two sections, we build on Nussbaum’s theory of compassion to describe the parallelism in the structure of compassion and engagement and to show their constitutive connection. Finally, we examine the specific way in which engaged acts “place burden” and transform a group into an institution. (shrink)

The aim of this paper is to show, contra the right-libertarian critique of social justice, that there are good reasons for defending policies of social justice within a free society. In the first part of the paper, we will present two influential right-libertarian critiques of social justice, found in Friedrich Hayek's Law, Legislation and Liberty and Robert Nozick's Anarchy, State and Utopia. Based on their approach, policies of social justice are seen as an unjustified infringement on freedoms of individual members (...) of a society. In response to this critique, we will introduce the distinction between formal and factual freedom and argue that the formal principle of freedom defended by Hayek and Nozick does not suffice for the protection of factual freedom of members of a society, because it does not recognise (1) the moral obligation to help those who, without their fault, lack factual freedom to a significant degree, and (2) the legal obligation of the state to protect civic dignity of all members of a society. In the second part of the paper, we offer an interpretation of Kant's argument on taxation, according to which civic dignity presupposes factual freedom, in order to argue that Kant's justification of taxation offers good reasons for claiming that the state has the legal obligation to protect factual freedom via the policies of social justice.

Bosonic and fermionic particle currents can be introduced in a more unified way, with the cost of introducing a preferred spacetime foliation. Such a unified treatment of bosons and fermions naturally emerges from an analogous superstring current, showing that the preferred spacetime foliation appears only at the level of effective field theory, not at the fundamental superstring level. The existence of the preferred spacetime foliation allows an objective definition of particles associated with quantum field theory in curved spacetime. Such an (...) objective definition of particles makes the Bohmian interpretation of particle quantum mechanics more appealing. The superstring current allows a consistent Bohmian interpretation of superstrings themselves, including a Bohmian description of string creation and destruction in terms of string splitting. The Bohmian equations of motion and the corresponding probabilistic predictions are fully relativistic covariant and do not depend on the preferred foliation. (shrink)

After Husserl?s transcendental turn and the discovery of the correlation between consciousness and the world the concept of the noema becomes one of the constant leitmotifs of Husserl?s philosophy. My paper will be devoted to the clarification of this concept and its implications for Husserl?s theory of sense. The leading question will be: How can the noema play the role of both the sense and the objective correlate of the intentional act? I will start with presenting the problematic of sense (...) in Husserl?s phenomenology from the Logical Investigations to the Ideas I. The central part of my paper will be devoted to the influential debate regarding the interpretation of the noema. Finally, I intend to point out the most important ways in which the notion of the noema becomes enriched in later Husserl?s philosophy, as well as the difference between linguisitic and non-linguistic sense, based on the Analyses Concerning Passive and Active Synthesis. I hope to show that Husserl?s phenomenological theory of sense offers a valuable alternative to the exclusively language-oriented theories of sense. (shrink)

Polazeci od jedne Fukoove opaske o vaznosti Kantovog razumevanja prosvetiteljstva za modernu filozofiju uopste, u ovom tekstu pokusavamo da sledimo trag veze izmedju pitanja o aktuelnosti, prosvetiteljstva i moderne kod Kanta. Ideje slobode i subjektivnosti uocavamo kao nezaobilazne za razumevanje kantovskog prosvetiteljskog projekta i njegove aktuelnosti. U tekstu pokusavamo da pokazemo kako se kod Kanta nailazi na specificno moderno shvatanje aktuelnosti koje ima dalekosezne ontoloske posledice, narocito u pogledu kategorije mogucnosti. Na osnovu sprovedenih analiza dolazimo do teze da se odgovor (...) na pitanje o aktuelnosti prosvetiteljstva ispostavlja kao ulog u borbi za ostvarenje nemoguceg. (shrink)

This paper presents the results of research on changes in attitudes towards music education among teacher education students who were exposed to vocal-instrumental lessons over the course of two semesters. The research was conducted among second-year students of teacher education at the Faculty of Education in Osijek, Croatia. The results have shown that students’ attitudes towards music education are relatively positive both before and after exposure to music lessons. Students with choir experience had more positive attitudes towards music education. Although (...) positive attitudes after music lessons are somewhat higher, there is no statistically significant difference between the attitudes of students before or after music lessons. Further research on attitudes towards music education is suggested across a larger population of teacher education students, over a longer period of time, and using a wider range of instruments. U radu su predstavljeni rezultati istraživanja mogućnosti promjena stavova studenata učiteljskoga studija o glazbenom obrazovanju nakon dva semestra vokalno-instrumentalne nastave. Istraživanje je provedeno sa studenticama druge godine učiteljskoga studija na Fakultetu za odgojne i obrazovne znanosti u Osijeku, Hrvatska. Rezultati su pokazali kako studentice imaju relativno pozitivne stavove o glazbenom obrazovanju prije i poslije nastave glazbe, a pozitivniji stavovi su zabilježeni kod studentica koje imaju iskustvo pjevanja u zboru. Iako se može uočiti trend pozitivnijih stavova nakon nastave glazbe razlika u stavovima studentica o glazbenom obrazovanju prije i poslije nastave glazbe nije statistički značajna. Sugerira se istraživanje stavova o glazbenom obrazovanju na većem uzorku studenata učiteljskoga studija, kroz duže vremensko razdoblje i to opsežnijim mjernim instrumentom. (shrink)

U radu se artikulisu i razvijaju ontoloske postavke i posledice Rusoovih razmatranja o slobodi, koje su u njegovim spisima cesto ostajale u drugom planu. Posebno se naznacuje jedan ontoloski bitan aspekt Rusoove radikalnosti, u kojem je raskidanje veza s prirodom, takozvani izlazak iz prirodnog stanja i sklapanje drustvenog ugovora, neodvojivo od njegovog razumevanja slobode, jednakosti i politicke delatnosti. Pokazuje se kako totalna alijenacija dovodi do radikalnog raskida s prirodom, a nenuzno iskrsavanje opste volje i uspostavljanje slobode kao samozakonodavstva tumaci se (...) kao dogadjaj politike, ciji uslov i zakon jeste opsta jednakost.

The aim of this paper is to clarify specific aspects of the impact of the brain-machine interface on our understanding of subjectivity. The brain-machine interface is presented as a phase of cyborgization of humans. Some projects in the field of brain-machine interface are aimed at enabling consensual telepathy - communication without symbolic mediation. Consensual telepathy refers to one of potential ways of transmission of information within singularity. Therefore, consensual telepathy is an important aspect of singularity. Singularity or human-machine symbiosis shows (...) some similarities with child-mother unity. Therefore, the psychodynamic perspective might be considered useful in thinking about human-machine symbiosis. Knowledge from developmental psychodynamic psychology combined with insights by Slavoj Zizek and Jean Baudrillard provides an additional perspective looking at human-machine symbiosis. The paper claims that if consensual telepathy becomes another way of communication, it will have the potential to annihilate subjectivity making it schizophrenic. At the same time, we look at the possibility of an escape from our inner world through the prism of addictions. (shrink)

Measurements of the dimensionality of chaotic attractors obtained on behavioral data represent the task complexity and also could be hypothesized to reflect the number of synchronized neural groups involved in the generation of the data. The changes in dimensionality for different experimental conditions suggest that limited processing capacity, task complexity, demand, and synchrony in neural firing might be closely related.

This essay discusses notions of community, commoning, and assemblage, in conjunction with new materialist and posthumanist onto-epistemologies and ethico-politics. The analysis is situated within, and applied to, current debates in ecological and community-oriented art, curating, and activism. The essay concludes with an articulation of what a “community of material-discursive commoning” may be constituted by, through, and with.

To relax the apparent tension between nonlocal hidden variables and relativity, we propose that the observable proper time is not the same quantity as the usual proper-time parameter appearing in local relativistic equations. Instead, the two proper times are related by a nonlocal rescaling parameter proportional to |ψ|2, so that they coincide in the classical limit. In this way particle trajectories may obey local relativistic equations of motion in a manner consistent with the appearance of nonlocal quantum correlations. To illustrate (...) the main idea, we first present two simple toy models of local particle trajectories with nonlocal time, which reproduce some nonlocal quantum phenomena. After that, we present a realistic theory with a capacity to reproduce all predictions of quantum theory. (shrink)
