Over recent years, brain-computer interface (BCI) has emerged as an alternative communication system between the human brain and an output device. Deciphered intents, after detecting electrical signals from the human scalp, are translated into control commands used to operate external devices, computer displays and virtual objects in the real-time. BCI provides an augmentative communication by creating a muscle-free channel between the brain and the output devices, primarily for subjects having neuromotor disorders, or trauma to nervous system, notably spinal cord injuries (...) (SCI), and subjects with unaffected sensorimotor functions but disarticulated or amputated residual limbs. This review identifies the potentials of electroencephalography (EEG) based BCI applications for locomotion and mobility rehabilitation. Patients could benefit from its advancements such as wearable lower-limb (LL) exoskeletons, orthosis, prosthesis, wheelchairs, and assistive-robot devices. The EEG communication signals employed by the aforementioned applications that also provide feasibility for future development in the field are sensorimotor rhythms (SMR), event-related potentials (ERP) and visual evoked potentials (VEP). The review is an effort to progress the development of user’s mental task related to LL for BCI reliability and confidence measures. As a novel contribution, the reviewed BCI control paradigms for wearable LL and assistive-robots are presented by a general control framework fitting in hierarchical layers. It reflects informatic interactions, between the user, the BCI operator, the shared controller, the robotic device and the environment. Each sub layer of the BCI operator is discussed in detail, highlighting the feature extraction, classification and execution methods employed by the various systems. All applications’ key features and their interaction with the environment are reviewed for the EEG-based activity mode recognition, and presented in form of a table. It is suggested to structure EEG-BCI controlled LL assistive devices within the presented framework, for future generation of intent-basedmultifunctional controllers. Despite the development of controllers, for BCI-based wearable or assistive devices that can seamlessly integrate user intent, practical challenges associated with such systems exist and have been discerned, which can be constructive for future developments in the field.

The pointwise ergodic theorem is nonconstructive. In this paper, we examine origins of this non-constructivity, and determine the logical strength of the theorem and of the auxiliary statements used to prove it. We discuss properties of integrable functions and of measure preserving transformations and give three proofs of the theorem, though mostly focusing on the one derived from the mean ergodic theorem. All the proofs can be carried out in ACA₀; moreover, the pointwise ergodic theorem is equivalent to (ACA) over (...) the base theory RCA₀. (shrink)

Kripke-style models with two accessibility relations, one intuitionistic and the other modal, are given for analogues of the modal systemK based on Heyting's prepositional logic. It is shown that these two relations can combine with each other in various ways. Soundness and completeness are proved for systems with only the necessity operator, or only the possibility operator, or both. Embeddings in modal systems with several modal operators, based on classical propositional logic, are also considered. This paper lays the ground for (...) an investigation of intuitionistic analogues of systems stronger thanK. A brief survey is given of the existing literature on intuitionistic modal logic.

Many tasks in statistical and causal inference can be construed as problems of entailment in a suitable formal language. We ask whether those problems are more difficult, from a computational perspective, for causal probabilistic languages than for pure probabilistic (or “associational”) languages. Despite several senses in which causal reasoning is indeed more complex—both expressively and inferentially—we show that causal entailment (or satisfiability) problems can be systematically and robustly reduced to purely probabilistic problems. Thus there is no jump in computational complexity. (...) Along the way we answer several open problems concerning the complexity of well-known probability logics, in particular demonstrating the ${\exists \mathbb {R}}$ -completeness of a polynomial probability calculus, as well as a seemingly much simpler system, the logic of comparative conditional probability.

Hannah Arendt is famous for her influential and innovative analysis of totalitarianism. However, her thinking on political systems and ideologies is far from limited to this theorization. Arendt also criti-cizes modern liberalism and its ideological framework. Indeed, Arendt’s thought reveals many of the political consequences of world-lessness, the loss of the world in contemporary times, particularly in terms of a sense of disempowerment and the advent of a technical vision of politics. This article looks at the political effects of world-lessness, (...) exploring the emerging opposition between liberal post-politics and conservative hyper-politics. This critique of Arendt’s thought can help us better understand the issues and questions raised by liberalism. (shrink)

Slovak Academic Philosophy: Its Origins, Development and Current State The paper introduces the foreign reader to the main factors associated with the emergence of Slovak academic philosophy as well as to the ways in which it has developed, and also to those factors that have complicated or delayed its progress since 1921 when the Faculty of Philosophy, along with its Philosophical Seminars, began functioning at the newly-founded University of Comenius (1919), up to the present day.

Recent discussion of the alleged adverse consequences of space colonization by Phil Torres in this journal is critically assessed. While the concern for suffering risks should be part of any strategic discussion of the cosmic future of humanity, the Hobbesian picture painted by Torres is largely flawed and unpersuasive. Instead, there is a very real risk that the skeptical arguments will be taken too seriously and future human flourishing in space delayed or prevented.

Ob množici del grških in rimskih piscev, ki so bila prevedena v slovenski jezik, je Livijeva Zgodovina doslej ostala nekako ob strani. Razen posameznih odlomkov ni bilo prevedenega nič. Količina ohranjenega besedila, avtorjev slog z dolgimi stavčnimi periodami, izbranim besediščem in različnimi retoričnimi prijemi, vse to pred­stavlja za prevajalca gotovo precejšnjo oviro. Z novo knjigo, ki je pred kratkim izšla pri Slovenski matici in prinaša prvih pet Livijevih knjig v prevodu Primoža Simonitija, se sedaj to spreminja. Knjigo je uredil David (...) Movrin, ki je napisal tudi spremno besedo in pripravil obsežen spremni aparat. Prevod zajema nekje sedmino ohranjenega Livijevega dela, ob predvidenem nadaljevanju s skupino prevajalcev si lahko obetamo izid nadaljnjih zvezkov in v doglednem času tudi prevod vsega, kar se je od Livija ohranilo v rokopisnem izročilu.

Cilj istraživanja bio je ispitati iskustva stresa kod odgojitelja i nastavnika tijekom COVID-19 pandemije te ispitati prediktivnu vrijednost nekih osobnih obilježja odgojitelja/nastavnika, izvora stresa, strategija suočavanja i socijalne podrške u objašnjenju doživljaja stresa, sagorijevanja na poslu i nade u budućnost. Online upitnik primijenjen je na uzorcima od 491 nastavnika i 316 odgojitelja. Rezultati su pokazali da su odgojitelji i nastavnici najvišu razinu stresa doživljavali tijekom prvog vala pandemije korona virusa te da je razina doživljenog stresa tijekom pandemije veća nego prije (...) pandemije. Odgojitelji uobičajene izvore stresa doživljavaju snažnijim nego specifične izvore stresa vezane za pandemiju korona virusa, dok je kod nastavnika obrnuto. Osobna obilježja odgojitelja/nastavnika, izvori stresa, strategije suočavanja i socijalna podrška povezani su s razinom stresa i sagorijevanjem na poslu te nadom u budućnost, ali se prediktivna vrijednost odnosno značajni prediktori razlikuju ovisno o kriteriju i skupini ispitanika.

This article examines the implications of Richard Steigmann-Gall's recent revisionist representation of Nazism as a Christian movement for the increasingly fashionable accounts of Nazism as a secular or political religion. Contrary to Steigmann-Gall's contention that Protestant Nazism undermines these accounts, I suggest that his portrayal of Nazism as a variant of Protestant millennialism is not necessarily inconsistent with the secular religion approach. A closer look at the so-called Löwith-Blumenberg debate on secularization indeed reveals that modern utopianisms containing elements of Protestant (...) millennialism are the best candidates for the label of secularized eschatology. That Steigmann-Gall has reached exactly the opposite conclusion is primarily because his conceptual understanding of secular religion is uninformed by the secularization debate. Insofar as Steigmann-Gall extracts his model of secular religion from contemporary political religion historiography on Nazism, this article points to a larger problem: a disjunction between historians utilizing the concept, on the one hand, and philosophers and social theorists who have shaped it, on the other.

Since the fall of the Berlin wall, the process of globalization has been understood as a necessary fate. The myth of the almightiness of the market economy, liberalization and deregulation is revitalized. Before us, there is a phenomenon Lacan?s discourse of University, which in 20 century was firstly given as a Stalinist discourse and today is given as a neo-liberal discourse of globalization. From underneath og a seeming objectivity, a Master insists-either the Party and the Capital. Just as the utopia (...) of the world proletarian revolution has fallen apart, the utopia of globalize capitalism and liberal democracy is also falling apart. The 9/11 event is opening opportunities for a construction of the field of social and political, out of the contour of the status quo. The coordinates of the possibility has changed and if we take the non-existence of the grand Autre on ourselves, then the contingence interference in the existent socio-symbolic order is possible. Posle pada berlinskog zida proces globalizacije je shvatan kao nuzna sudbina Revitaliziran je mit svemogucnosti trzisne privrede, liberalizacije i deregulacije. Ovaj fenomen moze se razumeti kroz diskurs Lacanovog "Univerziteta", koji se u 20. stolecu prvo prikazivao kao staljinisticki diskurs, a danas kao neoliberalisticki diskurs globalizacije. Uvek se ispod prividne objektivnosti univerzitetskog diskursa pokazuje Gospodar - ili Partija ili Kapital. Isto kao sto je propala utopija svetske proleterske revolucije, raspada se i utopija univerzaliziranog globaliziranog kapitalizma i liberalne demokratije. Dogadjaj od 11. septembra otvara mogucnosti za konstrukciju terena drustvenog i politickog izvan kontura status quo. Koordinate moguceg promenile su se i ako uzmemo na sebe ne-egzistenciju velikog Drugog, moguca je kontingentna intervencija u postojeci drustveno-simbolicni poredak. (shrink)

Procesi globalizacije događali su se mnogo puta u povijesti, daleko prije pojave riječi ‘globalizacija’ u drugoj polovici 20. st. Suvremena globalizacija podrazumijeva društvene, gospodarske i političke procese usmjerene na prelaženje državnih granica i stvaranje globalnog svjetskog poretka. No ona se ne smije svesti samo na to, budući da njeni procesi pogađaju sva područja ljudskog života i djelovanja: medije i komunikacije, gospodarstvo, politiku, pravo, kulturu, ekologiju, etiku, religije i crkve. Posljedice globalizacije jesu nova iskustva na društvenoj, političkoj i gospodarskoj razini – (...) povezivanje i umrežavanje kroz procese internacionalizacije i transnacionalizacije, kroz skupove poput G7 i Međunarodnog gospodarskog foruma u Davosu, ali i brojni društveni lomovi i gospodarska recesija. Globalizacija potiče religije na približavanje, na jačanje suradnje i na zauzimanje zajedničkog stava. Religije to i čine kroz postojeće zajedničke institucije, poput Svjetskog parlamenta religija i Svjetske konferencije religija za mir , tražeći nove oblike približavanja, dijaloga, solidarnosti, suživota, suradnje i ostvarenja etičkog konsenzusa, vodeći računa o zaštiti vlastitog identiteta u vremenu pluralizma i multikulturalnosti. Religije su svjesne da je etičko pitanje postalo pitanje planetarne odgovornosti koje zahtijeva globalnu etiku oko koje se trebaju složiti svi subjekti na svjetskoj razini, a u kojoj će čovjek biti aktivni subjekt. Kršćanske crkve uzimaju u obzir određene pozitivne zakonitosti procesa globalizacije tako da možemo govoriti o »kršćanskoj globalizaciji«. Kršćanstvo je od svojih početaka bilo usmjereno na određenu vrstu globalizacijskih procesa – daleko prije nego li se pojavio naziv ‘globalizacija’. Crkve su svjesne svoje zadaće zajednički braniti u vremenu globalizacije dostojanstvo svakog čovjeka, svake tradicije i kulture. One to čine preko brojnih postojećih međucrkvenih institucija na svjetskoj razini kao što su Ekumensko vijeće crkava , Ekumensko vijeće mladih u Europi . Katolička Crkva je od početka bila globalna i iz te je perspektive kroz stoljeća misijski djelovala. Nakon II. vatikanskog sabora to će djelovanje pojačati osnivanjem Papinskog vijeća za jedinstvo kršćana koje je nastalo iz Tajništva za jedinstvo kršćana , zatim Svjetskog dana mladih i Caritasa internationalisa.Processes of globalization have been happening numerous times through history, long prior to the appearance of the word ‘globalization’ in the second half of 20th century. Modern globalization includes the social, economic and political processes headed to crossing national boundaries and creating a global world order. However, globalization cannot be attributed simply to that issue, for its processes deal with all dimensions of human life and activity: media and communications, economy, politics, law, culture, ecology, ethics, religions, and churches. The consequences of globalization are new experiences related to social, political and economical sphere – interconnection and networking through processes of internationalization and transnationalization, through the meetings of the members of G7 and International Economic Forum in Davos, and also the numerous social breaks and economic recession. Globalization inspires religions to aim at the approaching, the stronger cooperation and the intercession for the common attitude. For realization of this purpose religions act through the existing common institutions like The World Parliament of Religions and World conference of religions for peace , asking for a new way of approaching, dialogue, solidarity, coexistence, cooperation and realization of ethic consensus, taking into account the protection of its own identity in time of pluralism and multiculture. Religions are aware of how ethic question has become the question of world’s responsibility. That issue requires global ethical principles around which all subjects on the world scale are to agree with. In that global ethic the human being will be respected as an active subject. The Christian Churches take into consideration the certain positive lawfulness of globalization process, thus we can speak of “Christian globalization”. Christianity has been headed to globalization process from the earliest days of the faith – prior to the process has emerged known as globalization. The Churches became aware of its responsibility in order to protect in the time of globalization the dignity of every person, every tradition, and culture. The Churches respond to this phenomenon through numerous existing interchurch institutions on world domain such as The World Council of Churches , Ecumenical Youth Council in Europe . The Catholic Church from the beginning has been global and based on this perspective the Catholic Church through centuries has been carrying out its missionary work. After the Second Vatican Council the Catholic Church has strengthened its activity by establishing Pontifical Council for Christian Unity , which has emerged from Secretariat for Promoting Christian Unity , World Youth Day and Caritas internationalis.

Quantification is particularly seductive in times of global uncertainty. Not surprisingly, numbers, indicators, categorizations, and comparisons are central to governmental and popular response to the COVID-19 pandemic. This essay draws insights from critical data studies, sociology of quantification and decolonial thinking, with occasional excursion into the biomedical domain, to investigate the role and social consequences of counting broadly defined as a way of knowing about the virus. It takes a critical look at two domains of human activity that play a (...) central role in the fight against the virus outbreak, namely medical sciences and technological innovation. It analyzes their efforts to craft solutions for their user base and explores the unwanted social costs of these operations. The essay argues that the over-reliance of biomedical research on “whiteness” for lab testing and the techno-solutionism of the consumer infrastructure devised to curb the social costs of the pandemic are rooted in a distorted idea of a “standard human” based on a partial and exclusive vision of society and its components, which tends to overlook alterity and inequality. It contends that to design our way out of the pandemic, we ought to make space for distinct ways of being and knowing, acknowledging plurality and thinking in terms of social relations, alterity, and interdependence.

In the past 50 years nurse scheduling has received considerable attention in the research community. There are two cases regarding the nurse scheduling problem : the static and dynamic. Dynamic NSP, is often called nurse rerostering problem, which presents reconstruction or modification of the predetermined roster for the current scheduling horizon. The aim of this paper is to present new hybrid strategy for nurse NRRP problem. The proposed methodology is based on efficient cooperation between fuzzy logic, ordered weighted averaging and (...) variable neighbourhood descent search. Complete system is tested, and experimental results are based on real-world dataset obtained from the Oncology Institute of Vojvodina in Serbia. (shrink)

The answer to the fine-tuning problem of the universe has been traditionally sought in terms of either design or multiverse. In philosophy circles, this is sometimes expanded by adding the option of explanatory nihilism – the claim that there is no explanation for statements of that high level of generality: fine-tunings are brute facts. In this paper, we consider the fourth option which, at least in principle, is available to us: co-evolution of the universe and obsevers. Although conceptual roots of (...) this approach could be found already in ancient stoicism, it is still the least investigated explanatory option for resolving the problem of empirical fine tunings. We offer two preliminary models along which the co-evolution hypothesis could be developed further. They are still on the level of speculative metaphysics, but there are opportunities along the way to generate predictions which are in principle testable, especially in the domain of large-scale numerical simulations.

We investigate intuitionistic propositional modal logics in which a modal operator is equivalent to intuitionistic double negation. Whereas ¬¬ is divisible into two negations, is a single indivisible operator. We shall first consider an axiomatization of the Heyting propositional calculus H, with the connectives →,∧,∨ and ¬, extended with . This system will be called Hdn . Next, we shall consider an axiomatization of the fragment of H without ¬ extended with . This system will be called Hdn + . (...) We shall show that these systems are sound and complete with respect to specific classes of Kripke-style models with two accessibility relations, one intuitionistic and the other modal. This type of models is investigated in [2] and [3], and here we try to apply the techniques of these papers to an intuitionistic modal operator with a natural interpretation. The full results of our investigation will be published in [4] and [1]. (shrink)

This article approaches the paradigm shift of datafication from the perspective of civil society. Looking at how individuals and groups engage with datafication, it complements the notion of “data politics” by exploring what we call the “contentious politics of data”. By contentious politics of data we indicate the bottom-up, transformative initiatives interfering with and/or hijacking dominant processes of datafication, contesting existing power relations or re-appropriating data practices and infrastructure for purposes distinct from the intended. Said contentious politics of data is (...) articulated in an array of practices of data activism taking a critical stance towards datafication. In data activism, data as mediators take a central role, both as part of an action repertoire or as objects of struggle in their own right. Leveraging social movement studies and science and technology studies, this theoretical essay argues that data activism can be mapped along two analytical dimensions: “data as stakes” vs. “data as repertoires”, and “individual practice vs. collective action”. Mapping action repertoires and tactics along these axes allows us to chart the potential emergence of a political data subject at the intersection of these two dimensions. This furthers our understanding of people’s engagement with data in relation to other forms of activism and existing work in social movement studies. It also helps us interpreting potential trajectories of contemporary social movements, as they increasingly interface with data, devices and platforms. (shrink)
