Measurement of gravitomagnetic field is of fundamental importance as a test of general relativity. Here we present a new theoretical project for performing such a measurement based on detection of the electric field arising from the interplay between the gravitomagnetic and magnetic fields in the stationary axial-symmetric gravitational field of a slowly rotating massive body. Finally it is shown that precise magnetometers based on superconducting quantum interferometers could not be designed for measurement of the gravitomagnetically induced magnetic field in the (...) cavity of a charged capacitor since they measure the circulation of a vector potential of electromagnetic field, i.e., an invariant quantity including the sum of electric and magnetic fields, and the general-relativistic magnetic part will be totally cancelled by the electric one which is in good agreement with the experimental results.

Alexander Sokurov’s latest film, Francofonia (2015), produced by the Louvre and filmed in France, takes up the issue of the Louvre in the middle of World War II and the Nazi occupation of Paris. This quasi-documentary, filmed along the lines of Sokurov’s signature documentary “elegies,” also encompasses the history of the Louvre up to the present day. Francofonia follows in the long line of Sokurov’s other films set in museums. Sokurov is an author who has worked more than any other (...) filmmaker to translate paintings into a cinematic medium. While engaging with art history and great museums, however, Sokurov also gives a poignant interpretation of the violence of history that often surrounds great works of art. Thus the museum, in Sokurov’s cinematic interpretation, is both an archive of the most valuable products of civilization, as well as a material monument to the founding cultural and political violence that produced and surrounds it. The overt scrutiny and hypervigilance with which Sokurov films museums affects the very mode of his filming: his camera operates as if it were a museum itself, each film becoming an attempt to save civilization from its own ruination, and from its own blindness. Every frame in Sokurov’s films is thus a freeze-frame, born out of the paralyzing tension between external historical nihilism and the beauty of art. (shrink)

In the first part of the paper, the author tackles the question of troubadour subjectivity. The subject of the poem announces the losing of oneself, abandonment of the existing state of affairs and self-surrender, but sees no tragedy in it, for a source of genuine joy. Love deserves sacrifice, it is worthy of all human desire, but it is not a conventional love, neither marital nor family love, rather, it is an ethereal and poetic love for Our Lady. For everything (...) that may be related to such love, we believe that a far more appropriate translation of gaya scienza is a joyful lesson, for it signifies far more to mark the troubadour point than the usual [Croatian/Serbian] translation cheerful doctrine. What is notably striking about the inherited solution is the complete misapprehension of the troubadour point, as the word science can only be associated with the troubadour wisdom if it is previously put in quotes. In short, the author concludes that a democratic scientist is happy and optimistic, while Nietzsche’s »joyful« scientist does not hesitate to show his anguished face publicly. The troubadour’s anguish for distant and unrealizable love is peculiarly close to Nietzsche’s suffering in a modern world that seems unable to live in a world of a distant and absent God. (shrink)

Study in the period of coronavirus disease 2019 lockdown and the effect of different exercise training programs on the quality of life dimension are limited. This randomized control study as a part of which the impact of an 8-week neuromuscular training program on the 90 healthy young individuals’ QoL after COVID-19 lockdown was assessed using a short form of the WHOQOL-BREF questionnaire comprising of four domains. The intervention group took part in a neuromuscular training program consisting of dynamic neuromuscular stabilization (...) and whole-body vibration training. In contrast, the control group did not participate in any programmed physical activity. From pre- to post-intervention test, the NT group significantly and substantially improved [mean change ] all the QoL domains, physical for 12.78 scores, psychological for 13.12 scores, social relationships for 20.57 scores, and environmental for 24.40 scores. These results suggest that the NT program could enhance QoL in young and healthy participants following COVID-19 lockdown. (shrink)

Optimization, in general, is regarded as the process of finding optimal values for the variables of a given problem in order to minimize or maximize one or more objective function(s). Brain storm optimization (BSO) algorithm solves a complex optimization problem by mimicking the human idea generating process, in which a group of people solves a problem together. The aim of this paper is to present hybrid BSO algorithm solutions in the past 5 years. This study could be divided into two (...) parts: strategies and applications. In the first part, different strategies for the hybrid BSO algorithms intended to improve the various ability of the original BSO algorithm are displayed. In the second part, the real-world applications in the past five years in optimization, prediction and feature selection processes are presented. (shrink)

Not so long ago, a well institutionalized predatory journal exposed itself by publishing a hoax article that blew the whistle for its devastating influence on the academic affairs of a small country. This paper puts that experiment in context, gives all the important details and analyzes the results. The experiment was inspired by well-known cases of scientific activism and is in line with recent efforts against predatory publishers. The paper presents the evidence in detail and uses it to analyze the (...) publishing practices of the offending journal, using established criteria for assessing predatory publications. That journal somehow acquired an impact factor and charged money to publish thousands of “scientific” papers without any peer review. Since the impact factor is the major official evaluation criteria for scientists in Serbia, these papers disturbed the whole academic evaluation process. Credentials acquired by those publications form a strong obstacle to institutionalized reasoned efforts against such practices. This case warns the whole community of the long lasting damage when journals with low publishing ethics are taken seriously. (shrink)

The aim of this paper is to demonstrate the hermeneutical method of Theodoret of Cyrus, who was one of the most important Biblical commentators and an influential theologian of the School of Antioch. This paper attempts to point out the fact that in the person of the Blessed Theodoret we find the first attempt of synthesis between the Antioch and Alexandria hermeneutical schools. In his hermeneutical work Theodoret attempted to overcome the contradictions existing up to that point and to follow (...) a middle way, without discarding neither the literal nor the spiritual-allegorical interpretation. It could be argued that Theodoret rejected the extreme hermeneutical trends of both the Alexandrian and Antioch inspirations; he developed his unique methods and tactics, which were rooted in the previous patristic tradition of the Church Fathers.

Početkom dvadesetog stoljeća Walter Benjamin ukazao je da s razvojem tehnike reproduciranja dolazi do gubljenja elitističkog statusa autora. S ekspanzijom tiska, filma i fotografije, svakome je, kako ističe, otvorena mogućnost dobivanja uloge u nekom filmu, pisanja nekog teksta koji bi potom bio objavljen u novinama, kreativnog izražavanja putem fotografije. Pojava interneta i novih medija ponovno aktualizira Benjaminovu teoriju. Razvoj cyber svjetova i mogućnost čovjekova kreativnog izražavanja unutar njih, u tekstu su dovedeni u vezu s pitanjem identiteta. Uključivanje čovjeka u cyber (...) prostor shvaćeno je kao otvaranje novih mogućnosti za ostvarenje čovjekovih kreativnih potencijala. U tome smislu, sudjelovanje čovjeka u cyber prostoru, čak i onda kada je usmjereno na stvaranje različitih predodžaba o samome sebi, shvaćeno je kao ostvarivanje čovjeka kao autora, a ne kao proces destabiliziranja čovjekova identiteta.At the beginning of the twentieth century Walter Benjamin pointed out that the development of techniques of reproduction leads to the loss of elite status of author. With the development of the press, film, and photography, as pointed out by Benjamin, everyone has an open possibility to gain a role in a movie, to be the author of a text which would then have been published in newspaper, or to creatively express through photography. Advent of the internet and new media actualized Benjamin’s theory. Development of cyber worlds and the possibility to one to creatively express himself into these worlds, in the text are linked to the question of identity. Inclusion of one in cyber space is understood as opening of new possibilities for the realization of one’s creative potentials. In that regard, the participation of one in cyber space, even when it is focused on creating different ideas about him, is understood as the realization of one as the author, and not as a process of destabilization of human identity.

Ako je u antičkom polisu Platona brinulo što se građani samodovoljno oslanjaju na vlastita uvjerenja o vrlinama, ne tragajući za znanjem, današnjeg žitelja globalnog pseudopolisa opčinjavaju simulirane informacije, slike i uvjerenja koja nezamislivim bujanjem kreiraju društvenu svijest. U sjenci masmedijskih pećina uočavaju se obrisi transformirane demokracije koja je sve izloženija silovitim naletima megakorporativnih interesa, dominantnih geopolitičkih utjecaja, kulturnog determinizma i redefiniranog vjerskog fundamentalizma. Usamljenom pojedincu na Agori sve je teže formirati i sačuvati vlastito mišljenje, ideje i vrijednosti. Infoprostor je pokriven (...) globalnom mrežom informacija i podataka, dok čin razmjene simboličkih sadržaja od čovjeka preuzimaju strojevi! Sloboda izražavanja medija je kisik otvorenog, javnog komuniciranja, stup demokratskih građevina, ali problem je u činjenici što čuvari informacijskih ulaza i dalje stražare, ovoga puta pred cyberprostorima.If Plato was upset that people leaned on their own convictions about virtues, without seeking knowledge, present resident of global pseudopolis is obsessed by simulated information, pictures and convictions, which create social consciousness with their hyperproduction. In shadow of massmedia’s caves, contours of transformed democracy can be seen. This democracy is more and more exposed to the interests of megacorporations, dominant geopolitical influence, cultural determinism, and redefined fundamentalism. Under such circumstances, to some lonely individual, “in Athena’s Agora”, is even more difficult to form and keep his or her own opinion, ideas and values. Infospace is covered by global network of information and facts; the process of symbolic exchange is taken off humans by machines. Freedom of speech in media is the air of open, public communication, the pillar of democratic structures, but problem is that watchmen of “information gates” still standing guard, but this time in front of cyber spaces.

ntroduction Since China’s gradualist reform started in the early 1980s, its governance record has been relatively successful. Despite a large number of severe challenges, the government in Beijing has managed outstanding economic performance and large-scale social transformation (Naughton 2007). Overall, the regime seems to enjoy relatively high levels of public support (Gilley 2006; Wang 2009), and a reform and state-building process controlled by the ruling Chinese Communist Party looks set to continue for the next ten to 20 years. One key (...) element of the Chinese political or governing system is management of its Party and government officials, or “cadres” in its own terminology. We argue that the Party-state’s personnel management features a meritocratic system that has so far largely evaded scholarly attention. This system retains strong influences from the Confucian scholar-official tradition of China’s imperial past, as well as the Leninist “vanguard party” tradition that was established in the revolutionary and Maoist eras. In recent years, however, this system has paid increasing attention to nurturing managerial competence for the purpose of administering a modern economy and a modern society. How the Party attempts to strike a balance between political loyalty and professional competence is the focus of this study. We will examine several aspects of the Chinese cadre management system. These include the formal rules, institutions, and actual practices regarding (1) recruitment, (2) development, and (3) promotion of officials. From this analysis we will understand how political loyalty and professional competence are defined and measured in the Party’s personnel regime, and how a balance is sought between the two. We will also look at the changes that are taking place in the relative importance, or weights, of these two criteria as the Party-state tries to build a modern governance machine. We find that while political reliability and commitment still feature prominently when the Party staffs the state and party bodies, rapid economic development and social changes have amplified the need for capable and competent managers and administrators, in order to deliver successful governance. Whereas in the past political loyalty played a crucial role for officials’ success within the state ranks, today professional competence has become more central. Whether this trend will continue, to a future state in which political loyalty becomes almost irrelevant, will be discussed toward the end of the chapter. (shrink)

In diesem Aufsatz wird betrachtet die Frage des Verhältnisses zwischen Natur und Menschen ausgehend vom alten unreflektierten Gebrauch des Ausdrucks Ethos im Sinne des gewöhnten Lebensortes, das von den es bewohnenden Lebewesen in bestimmten Ausmasse gestaltet wird. Diese Ausgangsposition wird weiter ausgearbeitet durch Begriffe des Heimortes bzw. der Heimwelt und Heimat. Verfasser vertritt die Auffassung, wonach dieser überlieferter Ethos-begriff den entsprechenden modernen Begriff nicht zu ersetzen vermag, er kann aber immerhin als seine zusätzliche Sinnbeilage verstanden werden. Die Letztere zeigt vielmehr (...) eine unerwartete Aktualität mit Rücksicht auf die gegenwärtige Problematik der Ökologie sowie Biodiversität. Hierbei wird vor allem die Frage geöffnet, welche Arten des Bewohnens als auch des Bodenkultivierens des jeweiligen Wohnortes sollen vorgezogen, und welche dagegen unterlassen werden. Als ein Imperativ hebt Verfasser die Notwendigkeit hervor eines umsichtigen Beziehens zu den anderen Lebewesen, zur Vegetation und natürlichen Umwelt mit denen wir das planetare Wohnort teilen, begleitet mit dem Respekt zur anderen, nicht-menschlichen Lebensformen sowie zu ihrem Wohlbefinden.

It is generally claimed that there exist exceptional circumstances when taking human life may be approved and when such actions may be justified on moral grounds. Precise guidelines in the medical field for making such decisions concerning patients who are terminally ill or have irreparable injuries incompatible with a bearable life, are difficult to establish. Recommendations that take the particular logical form of a rule, such as "in dubio pro vita", "when in doubt favour life") have been suggested and in (...) some countries incorporated into legal texts (Germany). We claim here that such a rule is of no value since it is open-ended and always allows for doubt, and a decision to employ measures that would support human life could always be argued to be a valid choice. Preservation of this rule could be encouraged, but giving it the force of law may put physicians at risk, as they may be challenged for choosing to terminate life in otherwise ethically and medically uncontroversial circumstances.

The wider topic to which the content of this paper belongs is that of the relationship between formal logic and real argumentation. Of particular potential interest in this connection are held to be substantive arguments constructed by philosophers reputed equally as authorities in logical theory. A number of characteristics are tentatively indicated by the author as likely to be encountered in such arguments. The discussion centers afterwards, by way of specification, on a remarkable piece of argument quoted in Cicero’s dialog (...) On Divination and ascribed to Stoic thinkers. The Stoics’ formal theory of inference is summarily referred to in this context, with special emphasis on their basic deductive schemata (‘indemonstrables’), some of them recognizable as links in the overall structure of the quoted argument. The main lines of Cicero’s criticism of the Stoic argument are next commented upon, with emphasis on his implied view as to the requirements of a good argument. Towards the end of the paper, a few considerations are added on the changes in the prevailing style of argumentation conspicuous in the three famous Roman Stoics. (shrink)

Following the general formalism presented by Rezzolla, Ahmedov and Miller, (1) we here derive analytic solutions of the electromagnetic fields equations in the internal and external background spacetime of a slowly rotating highly conducting magnetized neutron star. The star is assumed to be isolated and in vacuum, with a dipolar magnetic field not aligned with the axis of rotation. Our results indicate that the electromagnetic fields of a slowly rotating neutron star are modified by general relativistic effects arising from both (...) the monopolar and the dipolar parts of the gravitational field. The results presented here differ from the ones discussed by Rezzolla, Ahmedov and Miller (1) mainly in that we here consider the interior magnetic field to be dipolar with the same radial dependence as the external one. While this assumption might not be a realistic one, it should be seen as the application of our formalism to a case often discussed in the literature. (shrink)

The main goal of this work is to present the proof-theoretical and model-theoretical approaches to probabilistic logics which allow reasoning about independence and probabilistic support. We extend the existing formalisms [14] to obtain several variants of probabilistic logics by adding the operators for independence and confirmation to the syntax. We axiomatize these logics, provide corresponding semantics, prove that the axiomatizations are sound and strongly complete, and discuss decidability issues.
