The diverse and paradoxical nature of globalization processes has given rise to new social constellations that shape transnational, national and local spaces. The historicity of identities, their past and present conditions, the changes they went through, the ways they influence the feeling of full membership in a community and the differentiation derived from cultural diversity and pluralism underscore the need for revisiting theoretical explorations. This paper addresses past and present social, cultural and religious processes in an era of transformations derived (...) from the complexity of today’s interconnected world and on the light of historical encounters. The need for revising the singularity of social and cultural trajectories and the religious trends gravitating in society is approached through snapshots of a twofold historical encounter: between Modernity and Latin America, and between Judaism and Modernity. Both express entrenched dilemmas of the binaries periphery-center and universal-particular. While one of them raised the issue of the dominant program of Modernity as a Western project, the other was entailed in the assumptions of one hegemonic religious constellation. (shrink)

TPPP/p25 is a recently discovered, unstructured protein involved in brain function. It is found predominantly in oligodendrocytes in normal brain but is enriched in neuronal and glial inclusions of Parkinson's disease and other synucleinopathies. Its physiological function seems to be the dynamic stabilization of microtubular ultrastructures, as well as the projections of mature oligodendrocytes and ciliary structures. We reappraise the earlier belief that TPPP/p25 is a brain‐specific protein. We have identified and cloned two shorter (N‐terminal‐free) homologs of TPPP/p25 that behave (...) differently from each other and from TPPP/p25. Two unique cell models have been established and used to study the effect of the unstructured protein on the energy metabolism and the formation of pathological aggregates. Our data suggest that the intracellular level of TPPP/p25 influences the cell differentiation, proliferation and the formation of protein aggregates, and consequently, the etiology of central nervous system diseases.

In this commentary I discuss the role of types of knowledge and conceptual structures in lexical representation, revealing the explanatory potential of frame-based knowledge. Although frame-based lexical semantics is not alien to the theoretical model outlined in Jackendoff's conceptual semantics, testing its relevance to the analysis of the lexical evidence presented in his book has been left out of consideration.

A part of relativistic dynamics is axiomatized by simple and purely geometrical axioms formulated within first-order logic. A geometrical proof of the formula connecting relativistic and rest masses of bodies is presented, leading up to a geometric explanation of Einstein’s famous E = mc 2. The connection of our geometrical axioms and the usual axioms on the conservation of mass, momentum and four-momentum is also investigated.

In 1978, Yu. F. Borisov presented an axiom system using a few basic assumptions and four explicit axioms, the fourth being a formulation of the relativity principle; and he demonstrated that this axiom system had (up to choice of units) only two models: a relativistic one in which worldview transformations are Poincaré transformations and a classical one in which they are Galilean. In this paper, we reformulate Borisov’s original four axioms within an intuitively simple, but strictly formal, first-order logic framework, (...) and convert his basic background assumptions into explicit axioms. Instead of assuming that the structure of physical quantities is the field of real numbers, we assume only that they form an ordered field. This allows us to investigate how Borisov’s theorem depends on the structure of quantities. We demonstrate (as our main contribution) how to construct Euclidean, Galilean, and Poincaré models of Borisov’s axiom system over every non-Archimedean field. We also demonstrate the existence of an infinite descending chain of models and transformation groups in each of these three cases, something that is not possible over Archimedean fields. As an application, we note that there is a model of Borisov’s axioms that satisfies the relativity principle, and in which the worldview transformations are Euclidean isometries. Over the field of reals it is easy to eliminate this model using natural axioms concerning time’s arrow and the absence of instantaneous motion. In the case of non-Archimedean fields, however, the Euclidean isometries appear intrinsically as worldview transformations in models of Borisov’s axioms and neither the assumption of time’s arrow, nor the rejection of instantaneous motion, can eliminate them.

We present three natural but distinct formalisations of Einstein’s special principle of relativity, and demonstrate the relationships between them. In particular, we prove that they are logically distinct, but that they can be made equivalent by introducing a small number of additional, intuitively acceptable axioms.

Continuing work initiated by Jónsson, Daigneault, Pigozzi and others; Maksimova proved that a normal modal logic (with a single unary modality) has the Craig interpolation property iff the corresponding class of algebras has the superamalgamation property (cf. [Mak 91], [Mak 79]). The aim of this paper is to extend the latter result to a large class of logics. We will prove that the characterization can be extended to all algebraizable logics containing Boolean fragment and having a certain kind of local (...) deduction property. We also extend this characterization of the interpolation property to arbitrary logics under the condition that their algebraic counterparts are discriminator varieties. We also extend Maksimova's result to normal multi-modal logics with arbitrarily many, not necessarily unary modalities, and to not necessarily normal multi-modal logics with modalities of ranks smaller than 2, too.The problem of extending the above characterization result to no n-normal non-unary modal logics remains open.

This edited book offers a broad selection of interdisciplinary studies within cognitive science. The book illustrates and documents how cognitive science offers a unifying framework for the interaction of fields of study focusing on the human mind from linguistics and philosophy to psychology and the history of science. A selection of renowned contributors provides authoritative historical, theoretical and empirical perspectives on more than six decades of research with a special focus on the progress of cognitive science in Central Europe. Readers (...) encounter a bird’s eye view of geographical and linguistic diversity brought about by the cognitive revolution, as it is reflected in the writings of leading authors, many of whom are former students and collaborators of Csaba Pléh, a key figure of the cognitive turn in Central Europe, to whom this book is dedicated. The book appeals to students and researchers looking for the ways various approaches to the mind and the brain intersect. (shrink)

ABSTRACT The two main directions pursued in the present paper are the following. The first direction was started by Pigozzi in 1969. In [Mak 91] and [Mak 79] Maksimova proved that a normal modal logic has the Craig interpolation property iff the corresponding class of algebras has the superamalgamation property. In this paper we extend Maksimova's theorem to normal multi-modal logics with arbitrarily many, not necessarily unary modalities, and to not necessarily normal multi-modal logics with modalities of ranks smaller than (...) 2. To extend the characterization beyond multi-modal logics, we look at arbitrary algebraizable logics. We will introduce an algebraic property equivalent with the Craig interpolation property in algebraizable logics, and prove that the superamalgamation property implies the Craig interpolation property. The problem of extending the characterization result to non-normal non-unary modal logics also will be discussed. In the second direction pursued herein: for non-normal modal logic with one unary modality Lemmon [Lem 66] gave a possible worlds semantics. Here we give a more general possible worlds semantics for not necessarily normal multi-modal logics with arbitrarily many not necessarily unary modalities. Strongly related to the above is the theorem, proved, e.g., in Jóns son-Tarski [JT 52] and Henkin-Monk-Tarski [HMT 71], that every normal Boolean algebra with operators can be represented as a subalgebra of the complex algebra of some relational structure. We extend this result to not necessarily normal BAO's as follows. We define partial relational structures and show that every not necessarily normal BAO is embeddable into the complex algebra of a partial relational structure. This gives a possible worlds semantics for not necessarily normal multi-modal logics. (shrink)

This book features more than 20 papers that celebrate the work of Hajnal Andréka and István Németi. It illustrates an interaction between developing and applying mathematical logic. The papers offer new results as well as surveys in areas influenced by these two outstanding researchers. They also provide details on the after-life of some of their initiatives. Computer science connects the papers in the first part of the book. The second part concentrates on algebraic logic. It features a range of papers (...) that hint at the intricate many-way connections between logic, algebra, and geometry. The third part explores novel applications of logic in relativity theory, philosophy of logic, philosophy of physics and spacetime, and methodology of science. They include such exciting subjects as time travelling in emergent spacetime. The short autobiographies of Hajnal Andréka and István Németi at the end of the book describe an adventurous journey from electric engineering and Maxwell’s equations to a complex system of computer programs for designing Hungary’s electric power system, to exploring and contributing deep results to Tarskian algebraic logic as the deepest core theory of such questions, then on to applications of the results in such exciting new areas as relativity theory in order to rejuvenate logic itself.

The present study investigated the cross-cultural variations in parents' views on the role of play in child development and the primary purpose of preschool education from Ethiopia and Hungary. It also examined the cross-cultural variations in preschoolers' executive functions, the frequency of their engagement in home activities, and the role of these activities in the development of EF skills. Participants included 266 preschoolers with their parents. The independent samples t-test showed that Ethiopian parents view fostering academic skills for preschooler significantly (...) more important than their Hungarian counterparts do. We also found that while Ethiopian parents hold the belief that academic and cognitive development is the major purpose of preschool education, Hungarian prioritize social-emotional development and entertainment. Additionally, preschoolers in Ethiopia were reported to engage in academic and arts and crafts activities after preschool significantly more frequently than their Hungarian counterparts. On the contrary, preschoolers in Hungary were found to engage in fine-motor activities, solitary play, sports and other physical activities significantly more frequently than their Ethiopian counterparts. No significant differences were found in EF skills between preschoolers from Ethiopia and Hungary. Results from hierarchical regression analyses showed that, after accounting for age and SES, preschoolers' frequency of pretend play and their parents' play support beliefs were found to be small to medium-sized predictors of inhibitory control skills in both samples. However, children's frequency of having breakfast at home was another significant predictor in the Ethiopian sample only. The frequency of participation in arts and crafts and other fine-motor activities were found to be important predictors of preschoolers' visual-spatial working memory skills in the Ethiopian and the Hungarian samples, respectively. We also found that, after controlling for SES, parental play support was an important factor associated with preschoolers' shifting skills only in the Hungarian sample. Based on the findings, we made important conclusions. (shrink)

The aim of this paper is to contribute to the development of a theory of economic freedom. In this endeavor, we build our framework on the Hayekian notion of freedom because it explicitly embodies the obvious link between freedom and the state: freedom is an absence of state coercion except for that which enforces abstract, general rules known beforehand. We derive two propositions from this Hayekian thesis and elaborate on them, leading to a categorization of government actions from the viewpoint (...) of economic freedom in which the criterion against which coercive governmental actions must be evaluated is the rule of law, meaning a government’s reliance on general, abstract rules. As an implication, our framework allows us to argue for the imperative differentiation between “efficiency” and “economic freedom” as two separate criteria against which government actions can and must be evaluated. We also show that our framework may help explain the process through which economic freedom enhances growth. (shrink)

PurposeTo investigate how search engine users manipulate the rankings of search results. Search engines employ different ranking methods in order to display the “best” results first. One of the ranking methods is PageRank, where the number of links pointing to the page influences its rank. The “anchor text,” the clickable text of the hypertext link is another “ingredient” in the ranking method. There are a number of cases where the public challenged the Google's ranking, by creating a so‐called “Google bomb” (...) – creating links to pages they wanted to be highly ranked for given query. Google is chosen as the search engine, because it is currently by far the most popular search engine.Design/methodology/approachPageRank, one of the major parameters of Google's ranking algorithm is described, and the author explains how this algorithm is exploited by communities of users to promote a certain web page for a specific query. This process is called “Google bombing.” Recent reaction of Google to this phenomenon is also described.FindingsSpecific examples of “accomplished Google bombs” show that the public is able to manipulate search results.Originality/valueGoogle, instead of being an unobtrusive information retrieval tool has become highly influential in the web scenery. Some users pay for search engine optimization, while others utilize the power of the crowd to influence Google's rankings. This paper supports the claims of Introna and Nissenbaum regarding the power of search engines. (shrink)

This paper announces the first critical edition of Abhinavagupta’s commentary on the Bhagavadgītā in its Kashmirian recension, based on one Kashmirian Devanāgarī and seven Śāradā manuscripts in addition to two existing non-critical editions. The volume will also include a new edition of the Kashmirian recension of the Bhagavadgītā and a full French translation. After a short presentation of Abhinavagupta’s commentary and a discussion of previous work on the subject, the manuscripts used are listed and briefly described. The question and importance (...) of the Kashmirian recension of the Bhagavadgītā and problems of its edition are discussed in detail, with several textual examples. In order to give a sample of the Gītārthasaṃgraha’s contents, some of Abhinavagupta’s remarkable interpretations are also highlighted, in particular tantric or esoteric ones. An Appendix deals with the closely related question of Bhāskara the Vedāntin, his date, his provenance and the Gītā recension he probably used for his commentary. (shrink)

The impact of digital devices and the Internet has generated various changes at social, political, and economic levels, the repercussion of which is a great challenge characterized by the changing and globalized nature of today's society. This demands the development of new skills and new learning models in relation to information and communication technologies. Universities must respond to these social demands in the training of their future professionals. This paper aims to analyze the empirical evidence provided by international studies in (...) the last eleven years, related to the digital literacy of university students, including those pursuing degrees related to the field of education. Our findings highlight the fact that the digital literacy that is offered in universities to graduate/postgraduate students, in addition to treating digital literacy as a central theme, also focuses on perceived and developed self-efficacy. This is done by strengthening competencies related to digital writing and reading, the use of databases, the digital design of content and materials, and the skills to edit, publish or share them on the web, or applications aimed at treating digital literacy as emerging pedagogies and educational innovation. Secondly, we found studies related to digital competencies and use of the Internet, social networks, web 2.0, or the treatment of digital risks and their relationship with digital literacy. Thirdly, we found works that, in addition to focusing on digital literacy, also focused on different psychological constructs such as motivation, commitment, attitudes, or satisfaction.Systematic review registration:https://www.scopus.com/home.uri; https://www.recursoscientificos.fecyt.es/.

Although most business-owning families (BOFs) that operate large family firms practice community social engagement both in private via family foundations and in the business domain via community corporate social responsibility (CSR) programs, the relationship between their activities in the two domains remains unclear. Prior literature speculates that BOFs will deprioritize firms’ community CSR when they have family foundations as more efficient vehicles to achieve socioemotional wealth (SEW), which would imply that such BOFs are less ethical in operating their firms. We (...) contrast these speculations by enriching the socioemotional wealth (SEW) approach with instrumental stakeholder theory and cue consistency arguments and theorize that BOFs seek to ensure consistency between their activities in the two domains. Using data from 2008 to 2018 on the 95 largest US public family firms whose BOFs also operate private foundations, we show a positive relationship between family foundation giving and firm community CSR activity. Furthermore, we provide evidence for the boundary conditions of this relationship, showing that it is weaker for firms that do not share the family’s name and stronger for those firms with family leaders who also lead their families’ foundations.

Perceptual grouping has traditionally been thought to be governed by innate, universal principles. However, recent work has found differences in Japanese and English speakers' non-linguistic perceptual grouping, implicating language in non-linguistic perceptual processes (Iversen, Patel, & Ohgushi, 2008). Two experiments test Japanese- and English-learning infants of 5-6 and 7-8 months of age to explore the development of grouping preferences. At 5-6 months, neither the Japanese nor the English infants revealed any systematic perceptual biases. However, by 7-8 months, the same age (...) as when linguistic phrasal grouping develops, infants developed non-linguistic grouping preferences consistent with their language's structure (and the grouping biases found in adulthood). These results reveal an early difference in non-linguistic perception between infants growing up in different language environments. The possibility that infants' linguistic phrasal grouping is bootstrapped by abstract perceptual principles is discussed. (shrink)

It is essential for social robots to fit in the human society. In order to facilitate this process we propose to use the family dog’s social behaviour shown towards humans as an inspiration. In this study we explored dogs’ low level social monitoring in dog-human interactions and extracted individually consistent and context dependent behaviours in simple everyday social scenarios. We found that proximity seeking and tail wagging were most individually distinctive in dogs, while activity, orientation towards the owner, and exploration (...) were dependent on the context and/or the activity of the owner. The functional analogues of these dog behaviours can be implemented in social robots of different embodiments in order to make them acceptable and more believable for humans.

Multimodal prehabilitation is increasingly recognized as an important component of the pre-operative pathway in oncology. It aims to optimize physical and psychological health through delivery of a series of tailored interventions including exercise, nutrition, and psychological support. At the core of this prescription is a need for considerable health behavior change, to ensure that patients are engaged with and adhere to these interventions and experience the associated benefits. To date the prehabilitation literature has focused on testing the efficacy of devised (...) exercise and nutritional interventions with a primary focus on physiological and mechanistic outcomes with little consideration for the role of behavioral science, supporting individual behavior change or optimizing patient engagement. Changing health behavior is complex and to maximize success, prehabilitation programs should draw on latest insights from the field of behavioral science. Behavioral science offers extensive knowledge on theories and models of health behavior change to further advance intervention effectiveness. Similarly, interventions developed with a person-centered approach, taking into consideration individual needs and preferences will increase engagement. In this article, we will provide an overview of the extent to which the existing prehabilitation literature incorporates behavioral science, as well as studies that have explored patient's attitudes toward prehabilitation. We will go on to describe and critique ongoing trials in a variety of contexts within oncology prehabilitation and discuss how current scientific knowledge may be enhanced from a behavioral science perspective. We will also consider the role of “surgery schools” and detail practical recommendations that can be embedded in existing or emerging clinical settings. (shrink)

Multiple authorship is the universal solution to multi-tasking in the sciences. Without a team, each with their own set of expertise, and each involved mostly in complementary ways, a research project will likely not advance quickly, or effectively. Consequently, there is a risk that research goals will not be met within a desired timeframe. Research teams that strictly scrutinize their modus operandi select and include a set of authors that have participated substantially in the physical undertaking of the research, in (...) its planning, or who have contributed intellectually to the ideas or the development of the manuscript. Authorship is not an issue that is taken lightly, and save for dishonest authors, it is an issue that is decided collectively by the authors, usually in sync with codes of conduct established by their research institutes or national ministries of education. Science, technology and medicine publishers have, through independent, or sometimes coordinated efforts, also established their own sets of guidelines regarding what constitutes valid authorship. However, these are, for the greater part, merely guidelines. A previous and recent analysis of authorship definitions indicates that the definitions in place regarding authorship and its validity by many leading STM publishers is neither uniform, nor standard, despite several of them claiming to follow the guidelines as set forward by the International Committee of Medical Journal Editors or ICMJE. This disparity extends itself to ghost and guest authorship, two key authorship-related issues that are examined in this paper to assess the extent of discrepancies among the same set of STM publishers and what possible influence they might have on publishing ethics.

Most departments in any field of science that have a sound academic basis have discussion groups or journal clubs in which pertinent and relevant literature is frequently discussed, as a group. This paper shows how such discussions could help to fortify the post-publication peer review movement, and could thus fortify the value of traditional peer review, if their content and conclusions were made known to the wider academic community. Recently, there are some tools available for making PPPR viable, either as (...) signed or anonymous comments, or in a hybrid format. Thus, limited platforms are currently in place to accommodate and integrate PPPR as a supplement to traditional peer review, allowing for the open and public discussion of what is often publicly-funded science. This paper examines ways in which the opinions that emerge from journal clubs or discussion groups could help to fortify the integrity and reliability of science while increasing its accountability. A culture of reward for good and corrective behavior, rather than a culture that protects silence, would benefit science most. (shrink)

We investigate and develop further two models, the GRW model and the K model, in which the Schrödinger evolution of the wave function is spontaneously and repeatedly interrupted by random, approximate localizations, also called “self-reductions” below. In these models the center of mass of a macroscopic solid body is well localized even if one disregards the interactions with the environment. The motion of the body shows a small departure from the classical motion. We discuss the prospects and the difficulties of (...) observing this anomaly. As far a the influence of the surroundings on submacroscopic objects (like dust particles) is concerned, we show that the estimates obtained recently in the theory of continuous measurements and in the K model are compatible. Also, we elaborate upon the relationship between the models. Firstly, borrowing a line of thought from the K model, we find the transition region between macroscopic and microscopic behaviors in the GRW model. Secondly, we refine the propagation rule of the wave function in the K model with the help of the time-evolution equation proposed in the GRW model. (shrink)

This study examines processes through which social personae are conveyed by male Japanese students at a public university in Yokohama. Focusing on the frame-setting function of first person pronominals in contexts where there is no intra/inter speaker variation in the choice of FPP, this paper analyzes how speakers manage identity-associated discursive alignments related to a shared Okinawa prefecture background. The common experience of being from Okinawa prefecture and attending university far from home is the primary reason that these speakers are (...) close friends. However, analysis reveals speakers’ continual and active contention and re-formulation of this shared ‘Okinawan-ness’ and the personae to which it is linked. In particular, FPPs are implicated in speakers’ discussion of heterogeneity and/or local differences with respect to their Okinawa prefecture background. Strategic use of FPPs thus emerges as a salient tactic for speakers’ active negotiation of conversation relevant personae categories even in interactional contexts without variation. (shrink)

This article takes the interlinkages between law and politics as its starting point. It analyzes recent changes in the legislative style of education governance in Sweden as not only a species of crisis management, but also a long-term response to a series of tensions arising out of the push toward what has been identified as ‘juridification’ in many Western nations—the reliance on law and judicial means for addressing core moral predicaments, public policy questions, and political controversies. The article outlines the (...) notion of juridification at a theoretical level and highlights juridification processes and their possible ramifications on education. It argues that recent changes in the legislative style of education governance in Sweden not only reveal much about the commitments and implicit assumptions of modern regulatory and evaluative regimes, but also reflect the general impact of the rationalization of social and political life on the organization of government. The article provides a case with which to examine some of the theoretical underpinnings and implicit conceptual assumptions of modern regulatory and evaluative regimes as well as educational institutions’ relationships with the State. It shows that regulatory frameworks define the conceptualizations of what educational institutions do and thus of what actually gets done. (shrink)

According to estimates more than 400 biobanks currently operate across Europe. The term ‘biobank’ indicates a specific field of genetic study that has quietly developed without any significant critical reflection across European societies. Although scientists now routinely use this phrase, the wider public is still confused when the word ‘bank’ is being connected with the collection of their biological samples. There is a striking lack of knowledge of this field. In the recent Eurobarometer survey it was demonstrated that even in (...) 2010 two-thirds of the respondents had never even heard about biobanks. The term gives the impression that a systematic collection of biological samples can constitute a ‘bank’ of considerable financial worth, where the biological samples, which are insignificant in isolation but are valuable as a collection, can be preserved, analysed and put to ‘profitable use’. By studying the practices of the numerous already existing biobanks, the authors address the following questions: to what extent does the term ‘biobank’ reflect the normative concept of using biological samples for the purposes of biomedical research? Furthermore, is it in harmony with the so far agreed legal–ethical consensus in Europe or does it deliberately pull science to the territory of a new, ambiguous commercial field? In other words, do biobanks constitute a medico-legal fiction or are they substantively different from other biomedical research protocols on human tissues? (shrink)
