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)

The idea that the mind, i.e., common sense, is not an inherent human structure but a cultural system, has become a general assumption taken for granted by many. Richard Rorty’s post-Philosophical culture serves as an illustrative example. One of the most renowned representatives of the radical critique of the mind, i.e., of common sense, is the cultural anthropologist Clifford Geertz. He believes that we are in need of an ethnography based on the “thick description”. Geertz’s insights have strongly influenced the (...) postliberal theologians. Consequently, the centre of the theology—the faith—has once again been obscured. Therefore, this article seeks to emphasize the importance of faith, based on Josef Pieper’s sagacious insights.

Clustering is one of the most fundamental and essential data analysis tasks with broad applications. It has been studied in various research fields: data mining, machine learning, pattern recognition and in engineering, economics and biomedical data analysis. Headache is not a disease that typically shortens one’s life, but it can be a serious social as well as a health problem. Approximately 27 billion euros per year are lost through reduced work productivity in the European community. This paper is focused on (...) a new strategy based on a hybrid model for combining fuzzy partition method and maximum likelihood estimation clustering algorithm for diagnosing primary headache disorder. The proposed hybrid system is tested on two data sets for diagnosing headache disorder collected from Clinical Centre of Vojvodina in Serbia. (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)

Autor podrazumijeva činjenicu da su Crkva i kršćanstvo nastali, razvijali se i širili u ozračju grčko-rimske ili helenističke kulture u koju su, navješćujući vjeru u Krista, Otkupitelja i Spasitelja, unijeli određene sastojke tadašnje židovske kulture, omogućujući tako razvoj europske culture. U misionarskom djelovanju, posebno nakon otkrića Amerike, Crkva susreće i prihvaća i druge kulture. U novom vijeku Crkva sve više postaje svjesna važnosti tih kultura, da bi počevši s II. vatikanskim saborom počela govoriti o pluralizmu kultura, o važnosti autohtonih kultura (...) trećeg svijeta, tražeći načine kako ih plodonosno povezati s navještajem Evanđelja. Autor iznosi kako Crkva u dokumentima II. Vatikanskog Sabora, posebno u pastoralnoj konstituciji Gaudium et spes, naširoko govori o kulturi , prihvaćajući također činjenicu pluralizma kulturâ. U spomenutoj saborskoj konstituciji susrećemo definiciju kulture u br. 53. Govoreći o poslije-saborskom govoru Crkve o kulturi, autor analizira različite papinske dokumente i govore poslije II. vatikanskog sabora, dokumente različitih vatikanskih ureda, kao i one biskupa iz Latinske Amerike. Autor posebno analizira crkveni govor o problematici kulture i inkulturacije u navještaju vjere, želeći pokazati kako je Crkva u svojem djelovanju nakon Sabora susretala i prihvaćala nove izazove, posebno antropološki pristup kulturi i inkulturaciji, koji su je poticali da još jasnije progovori o kulturi, o pluralizmu kultura, i o inkulturaciji vjere na kraju dvadesetog stoljeća.The author comprehends the fact that the Church and Christianity emerged , developed and spread in the atmosphere of the Greek-Roman or Hellenistic culture in wich they brought, by proclamation the faith in Jesus Christ, the Redeemer and Savior, the certain ingredients of Jewish cultur, making in such way possible the developement of European culture. In missionary work, especially after the discovery of America, the Church meets and accepts the other cultures. In the modern world Church more and more becomes conscious of these cultures. Beginning with the Second Vatican Council the Church speaks of a plurality of cultures and the importance of authentic cultures of the third world in order to find the ways how to fertile connect cultures with the proclamation of Gospel. The author brings out that the Church in the documents of Second Vatican Council, particularly in the Pastoral Constitution Gaudium et spes, widely speaks of culture accepting the fact of a plurality of cultures. The same pastoral constitution brings the definition of the word ‘culture’ in the number 53. Based on the topic of culture after the Second Vatican Council the author analyzes the different papal document and speeches, the document of various Vatican offices, as well as documents of bishops from Latin America. The author particularly analyzes the Church’s speech founded on the problem of culture and inculturation in the proclamation of faith, in order to show how Church, in its work after the Second Vatican Council, met and accepted new challenges, especially anthropological admission to culture and inculturation, that gave an impulse to the Church to speak more clearly of culture, of a plurality of cultures and of inculturation of faith at the end of 20th century.

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.

The skin, uniquely positioned at the interface between the human body and the external world, plays a multifaceted immunologic role in human life. In medical practice, early accurate detection of all types of skin tumours is essential to guide appropriate management and improve patients’ survival. The most important issue is to differentiate between malignant skin tumours and benign lesions. The aim of this research is the classification of skin tumours by analysing medical skin tumour dermoscopy images. This paper is focused (...) on a new strategy based on deep convolutional neural networks which have recently shown a state-of-the-art performance to define strategy to automatic classification for skin tumour images. The proposed system is tested on well-known HAM10000 data set. For experimental results, verification is performed and the results are compared with similar researches. (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.

A growing body of work has highlighted the importance of political beliefs and attitudes in predicting endorsement and engagement in prosocial behavior. Individuals with right-wing political orientation are less likely to behave prosocially than their left-wing counterparts due to high levels of Right-wing authoritarianism. Here, we aimed to extend prior work by testing how political values relate to COVID-19 discretionary behavioral intentions. Furthermore, we tested whether identification with the national group would influence the relationship between RWA and prosocial behavior. A (...) cross-sectional study conducted on 350 Italian participants showed that right-wing political orientation had a negative effect on COVID-19 discretionary behavioral intentions via RWA. Furthermore, a moderated mediation model revealed that this effect was only significant for participants who are lowly identified with the national group. The results suggest that highlighting group belongingness might effectively motivate more conservative individuals to engage in prosocial behavior. (shrink)

‘Feminist competency’ is a nascent term that has been identified in three general critiques of contemporary feminism that emerged in the course of research for The Great Feminist Denial (2008), a book on feminist debates in Australia that I co-authored with Monica Dux. The first critique highlights the importance of feminist knowledge, typically generated through the academy, to feminist identification. The second posits a perceived lack of feminist competency as an obstacle to feminist affiliation. The third assessment insists that spokespeople (...) for feminism should be sufficiently competent. Using these responses to feminism as a starting point, combined with a reflection on my own framing as an academic feminist in the public sphere, I make a case for the potential value of ‘feminist competency’ as a means to assess the impact of academic feminism, in Australia and elsewhere.

This paper will analyse what it takes to conduct feminist and sensitive research in countries that have seen mass human rights violations. Transitional justice research involves critical examination of difficult topics which raises a number of ethical and methodological issues for both the participants and the researchers. Although empirical research has been a facet of the studies produced in the field, researchers’ accounts of undertaking research in often politically sensitive environments is largely missing from published books and research reports. This (...) paper is informed by personal experiences of doing research in wartime rape in the ethnically and politically divided country of Bosnia and Herzegovina. I argue that the researcher’s profile and positionality directly affects the fieldwork and that fieldwork is a dialogical process which is structured by the researcher and the wider political processes in the country.

The article analyzes the economic determinants of the rise and initial growth of Protestantism, specifically Calvinism, described as the Weber reverse problem in light of his thesis of Calvinist outcomes for economy. These determinants of Calvinism are differentiated from its assumed economic outcomes, specifically the emergence and development of modern capitalism in Weberian sociological accounts. It is argued and showed that the economic determinants of Calvinism’s emergence and early evolution are primarily pre-capitalist in character rather than capitalist in the modern (...) sense. Therefore, the initial overarching economic determinant and setting of early Calvinism is considered to be pre-capitalism, as distinguished from modern industrial capitalism, specifically feudalism as the ancien regime of master–servant economy. Such a pre-capitalist determinant and context suggests that of Calvinism was itself economically determined or influenced before presumably determining or influencing modern capitalism.. (shrink)

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.

:There are manifold intriguing issues located within largely unexplored borderlands of bioethics, future studies, and astrobiology. Human enhancement has for quite some time been among the foci of bioethical debates, but the same cannot be said about its global, transgenerational, and even cosmological consequences. In recent years, discussions of posthuman and, in general terms, postbiological civilization have slowly gained a measure of academic respect, in parallel with the renewed interest in the entire field of future studies and the great strides (...) made in understanding of the origin and evolution of life and intelligence in their widest, cosmic context. These developments promise much deeper synergic answers to questions regarding the long-term future of enhancement: how far can it go? Is human enhancement a further step toward building a true postbiological civilization? Should we actively participate and help shape this process? Is the future of humanity “typical” in the same Copernican sense as our location in space and time is typical in the galaxy, and if so, can we derive important insights about the evolutionary pathways of postbiological evolution from astrobiological and Search for ExtraTerrestrial Intelligence studies? These and similar questions could be understood as parts of a possible unifying research program attempting to connect cultural and moral evolution with what we know and understand about their cosmological and biological counterparts.

Headache disorders can be considered as the predominant neurological condition. In the field of neurological diseases, migraine was estimated to cost a total of €27 billion per year for the loss through reduced work productivity in the European Community. Medical data and information in turn provide knowledge based on which physicians make scientific decisions for diagnosis and treatments. It is, therefore, very useful to create diagnostic tools to help physicians make better decisions. This paper is focused on a new hybrid (...) clustering system combining analytic hierarchy process and weighted fuzzy c-means clustering method for diagnosing children with primary headache disorder. The proposed three-stage hybrid diagnosing system is tested on data set collected from hospitalized children in the Clinical Centre of Vojvodina, Novi Sad, Serbia. (shrink)

Clearance phase at signalized crosswalks is an important parameter of pedestrians’ safety because it helps them to complete the crossing before the green signal for vehicles. However, there is the issue of pedestrian decision as to whether to cross if they arrive at the crosswalk during the clearance phase, which represents a violation in many countries. Due to the proof that pedestrian violations multiply the risk of traffic accidents, in this study, the tendency of pedestrians to commit violations during the (...) clearance time has been researched. With the aim of proposing the design of the pedestrian traffic lights, which could decrease the frequency of pedestrian violations, the comparison of pedestrians behaviour at crosswalks with and without a countdown timer during the clearance time was made, based on the data collected in the video recording. Chi square independency test showed that there is a statistically significant difference in the behaviour of pedestrians during the clearance time, depending on the existence of the timer, as well as the fact that pedestrians behave in a safer manner if there is no clearance time shown on the timer. The total delay rate on the roadway during the red signal, which was the consequence of starting the crossing during the clearance time or subsequent violations, was 1.3 times higher at the crosswalks with the countdown timer. This research was unique because for the first time, two-phase pedestrian crossings on the roadway with the median refuge island in the sense of clearance time were analysed, in spite of the previous proof that pedestrians are more likely to commit violations during the red signal in that kind of roadway. Another novelty in the research was pedestrians following till the end of crossing, due to the possibility of subsequent violations. With the means of binary logistic regression, different factors which affect pedestrians’ behaviour during the clearance time have been determined and they differ depending on the existence of the timer. At the pedestrian crosswalks with the timer, contributing factors have been determined, such as gender, the number of waiting pedestrians, distractions, arrival time, and age. If there is no timer, the contributing factors are the following: the number of crossing pedestrians, distractions, group, position of pedestrians in relation to the vehicle, the number of traffic lanes, and age. Based on the obtained results, a new design of the pedestrian traffic lights was proposed. (shrink)
