In transparent orthographies, persistent reading fluency difficulties are a major cause of poor reading skills in primary school. The purpose of the present study was to investigate effects of a syllable-based reading intervention on word reading fluency and reading comprehension among German-speaking poor readers in Grade 4. The 16-session intervention was based on analyzing the syllabic structure of words to strengthen the mental representations of syllables and words that consist of these syllables. The training materials were designed using the 500 (...) most frequent syllables typically read by fourth graders. The 75 poor readers were randomly allocated to the treatment or the control group. Results indicate a significant and strong effect on the fluency of recognizing single words, whereas text-level reading comprehension was not significantly improved by the training. The specific treatment effect provides evidence that a short syllable-based approach works even in older poor readers at the end of primary school. (shrink)

Nostalgia for the 1980s, or 80stalgia, is a global phenomenon. This article explores the phenomenon in Greece and approaches 80stalgia as a cultural trend that marks media and pop culture. It combines digital ethnography through invisible observation (especially using Facebook, a social medium that favours nostalgic communities) and historicised content analysis to analyse 80stalgia in its interrelation with politics, and approaches it as having been influenced by international nostalgic trends and local politics, especially the political legacy of 1980s governments. Finally, (...) the article discusses why the economic crisis of the 2010s, an experience that triggered self-reflection on the past, strengthened 80stalgia. (shrink)

The ontic conception of explanation is predicated on the proposition that “explanation is a relation between real objects in the world” and hence, according to this approach, scientific explanation cannot take place absent such a premise. Despite the fact that critics have emphasized several drawbacks of the ontic conception, as for example its inability to address the so-called “abstract explanations”, the debate is not settled and the ontic view can claim to capture cases of explanation that are non-abstract, such as (...) causal relations between events. However, by eliminating the distinction between abstract and non-abstract explanations, it follows that ontic and epistemic proposals can no longer contend to capture different cases of explanation and either all are captured by the ontic view or all are captured by the epistemic view. On closer inspection, it turns out that the ontic view deals with events that fall outside the scientists’ scope of observation and that it does not accommodate common instances of explanation such as explanations from false propositions and hence it cannot establish itself as the dominant philosophical stance with respect to explanation. On the contrary, the epistemic conception does account for almost all episodes of explanation and can be described as a relation between representations, whereby the explanans transmit information to the explanandum and that this information can come, dependent on context, in the form of any of the available theories of explanation (law-like, unificatory, causal and non-causal). The range of application of the ontic view thus is severely restricted to trivial cases of explanation that come through direct observation of the events involved in an explanation and explanation is to be mostly conceived epistemically.

Do psychological perspectives constitute the only way through which the role of musical creativity in education can be addressed, researched and theorised? This essay attempts to offer an alternative view of musical creativity as a deeply social and political form of human praxis, by proposing a perspective rooted in the thought of the political philosopher and activist Cornelius Castoriadis (1922–1997). This is done in two steps. First, an attempt is made to place the pursuit of the concept of musical creativity (...) within a larger educational and societal context of conflicting trajectories that run through (a) Modernity and (b) Education. Then, I revisit the issue of educational value of improvising and composing through creating conceptual links between the process of music-making through improvisation and composition and the project of political autonomy as conceived by Castoriadis. By foregrounding instituting imaginary over instituted imaginary, improvising and composing become active processes of positing new legitimacies, and of creating a music-making context that searches for its own foundations. It is in and through creative musical praxis that we can think about issues of hierarchies, musical values, social dimensions of different music-making processes, our relationship to past values and to historical dimensions of music. By arguing that improvisation and composition might be seen as ways of positing the issue of political autonomy in musical terms, this paper emphasises the role of improvisation and composition as a mode of potentially transformative educational practice that may foster the development of critical consciousness, linking music education to a larger project of re-discovering and at the same time re-defining democracy.

This paper suggests a framework for re-thinking the relationships between power and knowledge in music education. Informed by Jacques Rancière’s notion of equality it explores how a dialectic between knowledge/mastery and ignorance/equality effects a rupture in the canonical relationships between knowledge and authority. Further, and based on a commentary of Alain Badiou, the paper explores the sense in which the Rancièrian perspective induces an understanding of equality as both a condition and a productive process: as a condition ignorance becomes the (...) radical root of the emergence of new knowledge; as a productive process it leads to the creation of a space where those who have been doomed to silence are able to appear. Following on from that, the paper explores how the supposition of equality might trigger the development of a “what if...?” attitude, transforming the pedagogic encounter to continuous exploration with the teacher starting by presupposing that she does not know anything until she and her student(s) begin building together, thus bringing students’ creative endeavors to the center of the music education encounter. This productive ignorance might have important consequences for how we think about notions of discipline and passionate engagement in music making, as well as music education’s relationships to music history and culture, remaining faithful to the aporetic dimension of music.

This monograph evaluates public policy responses to the Covid-19 pandemic through a public choice lens. The book compares two prominent, albeit mutually exclusive, theories in social sciences—public interest theory and public choice theory—and explores how their predictions perform within the framework of the Covid-19 pandemic. The chapters present different pandemic policies alongside empirical data in order to draw conclusions about their efficacy, and, in turn, draw conclusions about the veracity of each theory. By the end of the volume, the reader (...) will be able to draw their own conclusions about whether the pandemic policy responses served the public interest, as public interest theory suggests, or the personal interests of the politicians who implemented them, as public choice theory holds.

COVID-19 is not only a health emergency but also a strategic challenge for any politics of resistance, struggle and transformation. Understanding the social and political dynamics associated with morbidity and mortality and the many ‘ecologies of disease’ associated with the pandemic is necessary if we want to think beyond the limits of the lockdown strategy. It is here that the possibility of a democratic biopolitics emerges as part of a broader strategy for communism.

In A Philosophy for Communism: Rethinking Althusser Panagiotis Sotiris attempts a reading of the work of the French philosopher centered upon his deeply political conception of philosophy. Althusser's endeavour is presented as a quest for a new practice of philosophy that would enable a new practice of politics for communism, in opposition to idealism and teleology. The central point is that in his trajectory from the crucial interventions of the 1960s to the texts on aleatory materialism, Althusser remained a (...) communist in philosophy. This is based upon a reading of the tensions and dynamics running through Althusser's work and his dialogue with other thinkers. Particular attention is paid to crucial texts by Althusser that remained unpublished until relatively recently. (shrink)

Immersive virtual reality (VR) emerges as a promising research and clinical tool. However, several studies suggest that VR induced adverse symptoms and effects (VRISE) may undermine the health and safety standards, and the reliability of the scientific results. In the current literature review, the technical reasons for the adverse symptomatology are investigated to provide suggestions and technological knowledge for the implementation of VR head-mounted display (HMD) systems in cognitive neuroscience. The technological systematic literature indicated features pertinent to display, sound, motion (...) tracking, navigation, ergonomic interactions, user experience, and computer’s hardware that should be considered by the researchers. Subsequently, a meta-analysis of 44 neuroscientific or neuropsychological studies involving VR HMD systems was performed. The meta-analysis of the VR studies demonstrated that the new generation HMDs induced significantly fewer dropouts and VRISE. Importantly, the commercial versions of the new generation HMDs with ergonomic interactions had zero incidents of adverse symptomatology and dropouts. Solely, HMDs equivalent to or greater than the commercial versions of contemporary HMDs accompanied with ergonomic interactions are suitable for implementation in cognitive neuroscience. In conclusion, researchers’ technological competency, along with meticulous methods and reports pertinent to software, hardware, and VRISE, are paramount to ensure the health and safety standards and the reliability of neuroscientific results.

La fondation de Nicopolis est la réponse donnée par Rome aux problèmes de l'organisation politique, administrative et sociale de l'Épire méridionale et de l'Acarnanie. Aussi les constructions telles que l'aqueduc constituent-elles, par leur inscription dans le paysage urbain et rural, un symbole majeur de la romanisation. Or le tracé de cet aqueduc, long de près de soixante-dix kilomètres, est encore imparfaitement connu. Nous en avons donc repris l'étude en nous attachant à reconstituer les contraintes auxquelles sa construction avait été soumise, (...) ainsi que l'évolution géomorphologique récente des bassins-versants traversés. Au-delà de l'aspect technique et naturaliste, nous nous sommes également attachés à replacer l'aqueduc dans le contexte territorial et géopolitique de l'époque. (shrink)

La plaine d'Arta est constituée des alluvions des fleuves Louros et Arachtos ; elle offre un terrain particulièrement favorable à l'étude de l'évolution récente des deltas. L'analyse détaillée de l'évolution géomorphologique aide à reconstituer la centuriation romaine de la plaine d'Arta et à éclairer d'un jour nouveau un certain nombre de données historiques.

This paper aims to examine how specific aspects of Bakhtin's theoretical perspective might inform our understanding of improvisation. Moreover, it outlines the possible educational implications of such a perspective. Specifically, a sketch of a Bakhtinian conception of improvisation is proposed, a sketch which emphasizes the cultivation of an attitude of consciousness that leads to an understanding of improvised music making as an obligation to explore the unknown, to search for freedom through the responsibility to attend to the uniqueness of irrevocable (...) musical acts. Moreover, emphasis is given to the potential of improvisation to create a music-making context that counters monologic musical discourses, providing a site of resistance to fixity and closure. It is argued that improvisation is dialogic exactly because it creates a very special sense of interaction, which is characterized by unfinalizability and openness. At the same time, improvisation is in need of temporary finalizations which occur through the presence of the audience and the musicians' struggle to raise their minds 'above' their playing, looking at their music from outside and getting 'back in' again. It is hoped that such a perspective might provide the necessary theoretical tools for re-thinking the role of improvisation in music education. A Bakhtinian view on the experience of improvisation would, it is suggested, be educationally valuable exactly because it regards improvisation not as a problem-solving method but a problem-positing approach: as a musical practice that involves children and young people in the experiential pursuit of freedom and the understanding of the "ought" of imagining ways forward, countering monologue by allowing the flourishing of a polyphony of unmerged voices, constituting a distinctive chronotope which provides the possibility of an enactment of everyday living in musical terms. The decision to improvise marks the initiation of a search for a public musical space which is marked by the absence of fear, where exploration of musical freedom is pursued, where everything might happen but not anything goes.

Tangled Type Theory was introduced by Randall Holmes in [3] as a new way of approaching the consistency problem for $\mathrm {NF}$. Although the task of finding models for this theory is far from trivial (considering it is equiconsistent with $\mathrm {NF}$ ), ways of constructing models for certain fragments of it have been discovered. In this article, we present a simpler way of constructing models of predicative Tangled Type Theory and consequently of predicative $\mathrm {NF}$. In these new models (...) of predicative $\mathrm {NF}$, the universe is well-orderable and equinumerous to the set of singletons. (shrink)

Neuroplasticity, the capacity of the brain to induce changes in response to environmental stimuli, entails a continuous rearrangement of the neural network through a complex interaction between genetics and environment. Within this process, the plastic brain uses its internal representations to predict future conditions and proactively proceed to actions. It can be said that plasticity demands a rethinking of the concept of determinism as the process of coming-to-be is directly related to modifications produced by experience. Pure determinism and complete randomness (...) are the two ends of a spectrum of positions relevant to the debate of the existence of free will. However, none conceptually supports free decision-making. How brain activity and the conscious experience of volition are related to one another has been a matter of significant research, with a plethora of findings indicating that early brain signals precede the self-reported time of the decision to act. The meaning of these findings, however, has been debated at both a theoretical and empirical level and the controversy is still ongoing. Consciousness is intertwined with free will along the dimension of time as it would otherwise be purposeless, taking place right at the next moment. Electrical activity of the brain is a measure of neurophysiological function and contributes to the understanding of processes that underlie high-order cognitive functions. A multidisciplinary approach in the study of free will could be designed in a way that philosophical concepts are connected to neural correlates by psychologically functionalizing them in terms of cognitive abilities. Such abilities are at the margins of conscious and nonconscious sensory information and are closely linked to brain processes of executive functions like attentional control and working memory.

We present various results regarding the decidability of certain sets of sentences by Simple Type Theory. First, we introduce the notion of decreasing sentence, and prove that the set of decreasing sentences is undecidable by Simple Type Theory with infinitely many zero-type elements ; a result that follows directly from the fact that every sentence is equivalent to a decreasing sentence. We then establish two different positive decidability results for a weak subtheory of math formula. Namely, the decidability of math (...) formula and math formula. Finally, we present some consequences for the set of existential-universal sentences. All the above results have direct implications for Quine's theory of “New Foundations” and its weak subtheory math formula. (shrink)

In this thesis I discuss the epistemological problems Socrates' faces as he inquires in the early Platonic dialogues into the nature of virtue , the way these problems are brought to a head in the Meno, and the way in which Plato resolves them in the Phaedo. ;I argue that Socrates conducts his investigation on the assumption that a human being will be virtuous, and happy, if and only if he is successful in instilling in his soul the arrangement that (...) is objectively proper for it. To do that he must improve his epistemic standing in quite a specific way: he must come to know in a substantive and practically efficacious way what is good and bad in general. Possession of this knowledge, in addition to being what it is to instill virtue in one's soul, is also the necessary and sufficient condition for one's happiness. ;I then argue that recent claims that Socrates distinguishes between different epistemic standards and that he disavows knowledge in a strict, but not in a weaker, sense are versions of the Insincerity Thesis . The Insincerity Thesis lacks philosophical motivation, and textual support. ;In the light of this, Meno's challenge in the Meno becomes a real, not a sophistical, problem, given the Socratic connections between being virtuous, knowing what virtue is in a substantive way, and being able to give in account of what one knows. The final solution is delivered in the Phaedo: There is an ontological affinity between us qua souls and the constitutive elements of the world, the ethical world included, on the basis of which we are epistemically able to carve the world at its natural joints.

Different why-questions emerge under different contexts and require different information in order to be addressed. Hence a relevance relation can hardly be invariant across contexts. However, what is indeed common under any possible context is that all explananda require scientific information in order to be explained. So no scientific information is in principle explanatorily irrelevant, it only becomes so under certain contexts. In view of this, scientific thought experiments can offer explanations, should we analyze their representational strategies. Their representations involve (...) empirical as well as hypothetical statements. I call this the “representational mingling” which bears scientific information that can explain events. Buchanan’s thought experiment from constitutional economics is examined to show how mingled representations explain. (shrink)

Panagiotis Kanellopoulos explores children's talk about musical thinking through the study of their reflections on their own improvised music. He accepts the possibility that children's discourse on music is the beginning of their philosophizing about music, an idea that is related to the larger issue of how to develop a music education perspective that gives voice to the learners and welcomes experimentation, constantly questioning the assumptions we bring as music educators. Based on particular examples of discussions with eight-year old (...) children he explores the development of their discourse, interpreting the meaning of their thinking, and illustrating how they put forward issues that although they begin from concrete particulars point to issues usually confined to abstract philosophical concerns. Children's reflective potential as well as their particular views has important educational implications. Discussions with the children about their work highlight interpretation and meaning-formation at the center of their experience as artists. And musical improvisation emerges as a source of genuine musical experiences and a core means for the creation of communities of practice, dialogue, and reflection. (shrink)

Against the traditional interpretation of Doxa as intrinsically and thoroughly deceiving and untrustworthy, the present essay examines the passages which follow the self-characterization of the goddess’ speech as ‘deceitful.’ The traits of an extensive cosmogony and cosmology open up the possibility for discerning two aspects of Doxa: first a presentation of mortal erroneous opinions, but then also their correction within the framework of the ‘appropriate world-arrangement’ presented by the goddess.

In the past few years there has been a renewed interest in the work of Louis Althusser, although, in some cases, this interest has been one-sided, focusing mainly on his later writings on aleatory materialism. The three books reviewed in this article, however, offer balanced and insightful overviews of the totality of Althusser's work, placing it in the wider context of Marxist political and theoretical debates and stressing both its originality and strengths, but also its contradictions.

White liberals like to claim that they live in a post-racial society. Furthermore, they believe that most people do not sympathize with the far-right. However, it is not racism fueling right-wing extremism in North America and Western Europe but the dominant ideology, liberalism. Consequently, Slavoj Žižek argues that racism is a problem concerning “objective violence,” which he further breaks down into “symbolic violence” and “systemic violence.” These primarily target minority groups. Thus, “objective violence” best explains the West’s problematic views of (...) Muslims and Islam since it supports what Edward Said refers to as “Orientalism” and reproduces racist depictions of racialized communities. These are incredibly harmful since the West still perceives the Orient and its residents as violent, strange, and backward. These Orientalist attitudes ultimately lead to discrimination against Muslims and Arabs. Furthermore, this ideology naturalizes and legitimizes capitalist social relations while concealing racialization processes. (shrink)

The model of ownership psychology as a cognitive adaptation proposes that people flexibly navigate cognitive systems of cooperation and competition, thus enabling them to justify unethical behavior. We discuss how this model captures previous accounts of unethical behavior and propose that a disengagement heuristic can help us understand recent findings in the interconnection between scarcity psychology and unethical behavior.

When Gadamer elaborates his conception of philosophical hermeneutics as a transcendental inquiry, he appeals to Aristotle’s practical philosophy as a “model”, which can elucidate his own conceptualization of understanding as intrinsically bound to the specific circumstances of every interpretation. The explicit formulation of the analogy between Aristotelian ethics and philosophical hermeneutics provides a framework that clarifies Gadamer’s principal intention; it also reveals some of the crucial tensions inherent in the Aristotelian conception of practical philosophy and its relation to praxis and (...) phronêsis. In the 1970s, however, Gadamer suggests a practical transformation of hermeneutics, claiming for it the role of an “heir of the older tradition of practical philosophy”. Against Gadamer’s late “turn”, construed as a deviation from the initial analogy, I defend Aristotle’s practical philosophy as an exemplary model for philosophical hermeneutics, but I also maintain that the two projects pursue distinct epistemic goals.

Unter den philosophischen Strömungen des 20. Jh.s zeichnen sich die Existenzphilosophie und die Hermeneutik dadurch aus, dass sie sich nicht nur vielfach mit Aristoteles auseinandersetzten, sondern sich gerade durch diese Auseinandersetzung zu allererst entwickelten und ausgestalteten. Beide Disziplinen verbindet nicht nur das Lehrer-Schüler Verhältnis ihrer Hauptvertreter Martin Heidegger und Hans-Georg Gadamer, sondern auch eine sachliche Affinität – die aber in ihren Details strittig bleibt. Ebenso kontrovers sind Inhalt, Charakter und Intention der jeweiligen Bezugnahme der beiden Philosophen auf Aristoteles; generell konzentriert (...) sich dieser Bezug auf den Aristotelischen Begriff der Praxis, auf die dianoetische Tugend der Phronesis und auf den Aufweis der Spannungen, die zwischen den Facetten praktischer Rationalität im Aristotelischen Werk entstehen.

Until recently, cardiotoxicity in the setting of a malignant disease was attributed solely to the detrimental effects of chemo‐ and/or radio‐therapy to the heart. On this account, the focus was on the evaluation of well‐established cardiac biomarkers for the early detection of myocardial damage. Currently, this view has been revised. Cardiotoxicity is not restricted to a single organ but instead affects the endothelium as a whole. Indeed, it has come into light that not only cancer therapy but also malignant cells (...) per se can impair the cardiovascular system, through a paracrine and endocrine mode of action. Even more intriguingly, a clear interplay between molecular pathways involved in cancer and cardiovascular disease has become prevalent, suggesting a common nominator that governs the pathophysiology of these two entities. Taken together, our strategy in the quest of novel biomarkers in the emerging field of cardio‐oncology should be critically reshaped. (shrink)

Events regarding individuals’ preferences that do not always follow from standard measures such as “value of statistical life” or “quality-adjusted life years” as well as events that occur in some market-related settings which distort the information conveyed by price mechanisms, suggest that a notable chunk of what Hayek called “local knowledge” remains inaccessible by scientific tools and that only the individuals who interact in these local frameworks can have access to it. This casts serious doubt on the epistemic possibility of (...) economic calculation for if events in the local world do not observe the economic models, it is hard to see how central planners can have knowledge on them. Refined modeling strategies and cutting-edge Artificial Intelligence systems do not manage to overcome this hurdle. They may provide huge datasets in a data model, but since not all events represented in the data model are embeddable in known economic models, the knowledge problem is not evaded. Even if a theory ever manages to capture all possible events as they appear in the data model then we are left with a relationship between models (the theoretical model and the data model) with no direct access to the local world and thus the problem of accessibility of local knowledge remains unresolved.
