Human-Computer Interaction and games set a new domain in understanding people’s motivations in gaming, behavioral implications of game play, game adaptation to player preferences and needs for increased engaging experiences in the context of HCI serious games. When the latter relate with people’s health status, they can become a part of their daily life as assistive health status monitoring/enhancement systems. Co-designing HCI-SGs can be seen as a combination of art and science that involves a meticulous collaborative process. The design elements (...) in assistive HCI-SGs for Parkinson’s Disease patients, in particular, are explored in the present work. Within this context, the Game-Based Learning design framework is adopted here and its main game-design parameters are explored for the Exergames, Dietarygames, Emotional games, Handwriting games, and Voice games design, drawn from the PD-related i-PROGNOSIS Personalized Game Suite holistic approach. Two main data sources were involved in the study. In particular, the first one includes qualitative data from semi-structured interviews, involving 10 PD patients and four clinicians in the co-creation process of the game design, whereas the second one relates with data from an online questionnaire addressed by 104 participants spanning the whole related spectrum, i.e., PD patients, physicians, software/game developers. Linear regression analysis was employed to identify an adapted GBL framework with the most significant game-design parameters, which efficiently predict the transferability of the PGS beneficial effect to real-life, addressing functional PD symptoms. The findings of this work can assist HCI-SG designers for designing PD-related HCI-SGs, as the most significant game-design factors were identified, in terms of adding value to the role of HCI-SGs in increasing PD patients’ quality of life, optimizing the interaction with personalized HCI-SGs and, hence, fostering a collaborative human-computer symbiosis.

Biographical essays explore the careers of two major early photographers, Joseph-Philibert Girault de Prangey and William James Stillman. in addition, portfolios with works by Maxime Du Camp, John Beasley Greene, Francis Frith, Robert Macpherson, Adolphe Braun and others testify to the strength and consistency of other early photographers who captured the antique worlds around the Mediterranean."--BOOK JACKET.

Hegel’s Science of Logic is widely acknowledged as one of the greatest works of European philosophy. However, its contribution to arguably the most important philosophical problem, Pyrrhonian scepticism, has never been examined in any detail. Pyrrhonian Scepticism and Hegel's Theory of Judgement fills a great lacuna in Hegel scholarship by convincingly proving that the dialectic of the judgement in Hegel’s Science of Logic successfully refutes this kind of scepticism. Although Ioannis Trisokkas has written the book primarily for those students (...) of philosophy who already have an interest in Hegel’s epistemology and philosophy of language and/or his Science of Logic, it will also appeal to those who investigate the problem of scepticism independently of the Hegel corpus.

This paper counters an objection raised against one of Bertrand Russell’s lesser-known epistemological views, viz. ‘‘structural realism’’ (SR). In short, SR holds that at most we have knowledge of the structure of the external (i.e., physical) world. M. H. A. Newman’s allegedly fatal objection is that SR is either trivial or false. I argue that the accusation of triviality is itself empty since it fails to establish that SR knowledge claims are uninformative. Moreover, appealing to Quine’s notion of ontological relativity, (...) I suggest that far from being false, SR knowledge claims seem to be the most that we can hope for. (shrink)

Geoerchaeological Study in the site of Aghios Ioannis, Thasos The geoarchaeological research conduct at Aghios Ioannis give information to reconstruct the environmental changes in a small coastal plain since the Late Neolithic. Despite the human impact testified by the development of land use by cattle breeding and cultivation since this period and until the Antiquity period, they underline the lasting stability of the area. Intensive land use had begun really during the Late Antiquity period but the cultivation have (...) not deeply altered the environment and enhanced the soil erosion. The development of cattle breeding and fires of the vegetation during the Byzantine and the early Ottoman periods have lastingly changed the environment responses. The geomorphic system become more sensitive and the direct or indirect consequences of the fire activity are more dramatic. This research reveals the high diversity of the environmental responses to human activities changes and demonstrates the impossibility to define a global model of environmental and landscape changes even at the scale of a small Aegean island.

The linguistic foundations of science and technology include many terms that have been borrowed from ancient languages. In the case of terms with origins in the Greek language, the modern meaning can often differ significantly from the original one. Here we use the PubMed database to demonstrate the prevalence of words of Greek origin in the language of modern science, and call for scientists to exercise care when coining new terms.

Commentators have found Hobbes's translation of Thucydides? history puzzling. It was Hobbes's first publication and it preceded his earliest political treatise by more than a decade. Although towards the end of his life Hobbes himself claimed that he published it in order to warn his compatriots of the dangers of democracy and demagoguery, some commentators have dismissed his explanation as an attempt to tie it to his own political theory, in hindsight. Through an examination of Hobbes's preface and essay on (...) the life and history of Thucydides, published alongside his translation, this paper shows that Hobbes's view of Thucydides and his usefulness remained consistent throughout. Siding with Plutarch, Hobbes valued Thucydides for his ability to turn the auditor into a spectator, thereby protecting him, as far as possible, from the dangers of demagoguery. (shrink)

In June 2018 the Texan philosopher and distinguished bioethicist Tristram Engelhardt, Jr. crossed the great divide to meet his maker, as he would probably put it. His work remains till now the most systematic effort to fully revise Bioethics based on the doctrines of the Orthodox Christian theology, while it is also apreciseaccount ofEthics and Bioethics in the “after God” era. Engelhardt was anexcellent master of ancient Greek, medieval, western and eastern philosophy, and after heconverted from the Roman Catholic to (...) the Eastern Orthodox Church – officially the Orthodox Catholic Church – he indulged in the works of the Holy Fathers andbecame greatly influenced by them. This is clearlymanifest in his views and continuous reference to Fathers and Ecclesiastical Writers. His conversion crucially influenced not only his bioethical views, but also his entire philosophical system. This magnificent journey obviously turned the Texan philosopher into a true Theologist – not in the academic sense, but in the one the Orthodox Catholic Church accepts, according to which “a Theologist is a person of God, from God, before God and speaks to praise God”. Engelhardt was not the first to deal with bioethical issues under the spectrum of Orthodox Theology, but he was the first to unravel both secular and Western-Church Bioethics and suggest a totally different version of Bioethicsbased on the principles of Orthodox ethics, the ceremonial and esoteric life of the Orthodox Church, having previously made himself a true communicant of both the paternal tradition and dogmatic teaching.

Ovid's disclaimers in theArs Amatorianeed to be read in this context. My main argument is that, in his disclaimers, Ovid is rendering his female readership socially unrecognizable, rather than excluding respectable virgins andmatronaefrom his audience.Ars1.31–4, Ovid's programmatic statement about his work's target audience, is a case in point. A closer look at the passage shows that he does not necessarily warn off Roman wives and marriageable girls:este procul, uittae tenues, insigne pudoris,quaeque tegis medios instita longa pedes:nos Venerem tutam concessaque furta (...) canemusinque meo nullum carmine crimen erit.

Wonder is undoubtedly a term that floats around in today’s academic discussion both on ancient philosophy and on philosophy of education. Back in the 4th century B.C., Aristotle underlined the fact that philosophy begins in wonder, without being very specific about the conditions and the effects of its emergence. He focused a great deal on children’s education, emphasizing its fundamental role in human beings’ moral fulfillment, though he never provided a systematic account of children’s moral status. The aim of this (...) paper is to examine, on the one hand, if, to what extent, and under what conditions, Aristotle allows for philosophical wonder to emerge in children’s souls, and, on the other hand, how his approach to education may shed light to the link between wonder and the ultimate moral end, i.e. human flourishing. We will, thus, 1) try to offer a unified outlook of the philosopher’s views on children’s special cognitive and moral state, and 2) illustrate how wonder contributes in overcoming their imperfect state of being.

Hobbes's concept of the natural condition of mankind became an inescapable point of reference for subsequent political thought, shaping the theories of emulators and critics alike, and has had a profound impact on our understanding of human nature, anarchy, and international relations. Yet, despite Hobbes's insistence on precision, the state of nature is an elusive concept. Has it ever existed and, if so, for whom? Hobbes offered several answers to these questions, which taken together reveal a consistent strategy aimed at (...) providing his readers with a possible, probable, and memorable account of the consequences of disobedience. This book examines the development of this powerful image throughout Hobbes's works, and traces its origins in his sources of inspiration. The resulting trajectory of the state of nature illuminates the ways in which Hobbes employed a rhetoric of science and a science of rhetoric in his relentless pursuit of peace. (shrink)

This paper seeks to examine the relationship and the interaction between institutions, policy and the labour market in the light of the ideas of the first generation of institutional economists, who, in contrast to neoclassicals, conceived of the economy as a nexus of institutions, underlining, therefore, the significant role of institutional and non-market factors in the functioning of an economic system. They also criticised those who define (economic) welfare only in terms of efficiency and satisfaction of consumer interests; institutionalists instead (...) focus on issues related to justice, human self-development and labourers' welfare. In addition, early institutionalists paid considerable attention to the institutional framework of the labour market. In particular, the first generation of institutional economists highlighted the importance of institutions and other non-market parameters in determining the level of wages and employment (e.g. the role of the bargaining power of workers and employers). Furthermore, they made substantial contributions towards the field of labour policy and they were pioneers in the formulation of economic and social policy. Specifically, various modern institutions and labour market policies, such as unemployment benefits, industrial training and active employment policies, were implemented in the US, during the first decades of the 20th century, after the recommendation of the institutional labour economists. Therefore, their ideas, besides being interesting from a historical point of view, may also be useful in today's analysis of workers' problems and the functioning of modern labour markets. (shrink)

Spinoza’s definition of ‘attribute’ has been described as ‘one of the most puzzling passages in the Ethics’ and ‘a longstanding worry’ for Spinoza interpreters. Its puzzling status stems from its apparent ‘subjectivist’ character and the dominant understanding of Spinoza’s notion of attribute as an ‘objectivist’ notion. The paper aspires to remove this puzzlement by proposing and defending a reading of E1d4 in which it is understood to have two senses. First, I defend the objectivist character of Spinoza’s notion of attribute, (...) and explain why E1d4 is problematic within the framework of an objectivist interpretation of the Spinozistic attribute. Second, I propose a reading of E1d4 as having two senses and explain the cause of an apparent contradiction in E1d4. Finally, I devote the largest part of the paper to a defence of the Two-Sense Reading of E1d4. More specifically, I draw on four sources for this defence: the structure of E1d1 and E1d3, the content and form of E1p4 and its demonstration, Spinoza’s doctrine of parallelism and Descartes’ treatment of attribute and its influence on Spinoza.

Start-ups navigate complex challenges in today's business environment, requiring a delicate balance of economic, environmental, and social objectives for long-term success. This study investigates the pivotal factors within business models that drive sustained value creation for sustainability-focused start-ups. Through a comprehensive literature review encompassing environmental, social, and performance dimensions, we identify resilience as a primary component of sustainable decision-making, supported by adaptability and convenience. Emphasizing resilience and adaptability in decision-making processes enables sustainable start-ups to maintain competitive advantages while pursuing sustainability (...) goals. We advocate for a collaborative decision-making approach focused on long-term value creation through sustainability measures, providing a framework for developing or refining sustainable business models. Future research may further explore the identified success factors within sustainable start-ups. (shrink)

We investigate the impact of perceived greenwashing on customer satisfaction. Unlike prior research that largely examines customer perceptions associated with irresponsible behavior, we focus on cases where firms overcommit and/or do not deliver on promised socially responsible actions. We theorize that this type of greenwashing is associated with lower customer satisfaction because customers perceive greenwashing through the lens of corporate hypocrisy. Using data from the American Customer Satisfaction Index (ACSI) for U.S. companies during the period 2008–2016, we document a negative (...) link between perceived greenwashing related to green product innovation (GPI) and the ACSI index. We demonstrate that this effect is primarily triggered by corporate policies exceeding the corresponding implementation actions and not by lower levels of implementation. We also show that a firm’s capability reputation mitigates the negative effect of greenwashing on customer satisfaction. Moreover, we conduct an experiment and provide evidence confirming that GPI greenwashing is in fact perceived by customers as corporate hypocrisy. (shrink)

Socrates’ analogy between the city and the soul in the Republic is a crucial part of the dialogue, since it forms the basis for the interlocutors’ definition of justice. Critics allege that there are structural inconsistencies between the city and the soul, and that even if they were somehow structurally analogous, they are nevertheless dif- ferent. Why, then, would one expect that justice in one would be enlightening for the discovery of justice in the other? This paper examines the passages (...) in which the anal- ogy is developed and finds that Socrates’ claims regarding similarities between the city and the soul are not as far-fetched as critics assert. Criticisms of the analogy are shown to be misunderstandings arising from an unwillingness to accept the political implications of Socrates’ plan. Ultimately, the analogy rests on important structural similarities between the city and the soul, and is a powerful tool towards an under- standing of the individual, of the city and of justice.

The unauthorized 1650 publication of The Elements of Law broke Hobbes’s treatise into two parts that were inconsistent with his own division of the work. This obscured what is arguably the most important insight into Hobbes’s method: his account of how human beings use language to instigate and appease others. I review the evidence of how the publication history of the Elements resulted in a break between I.13 and I.14 that Hobbes did not intend. I then argue that as the (...) description of the very method that Hobbes was using to counteract dangerous dogmatists and appease his fellow citizens, the discussion in question made sense in a work intended for private circulation but not in treatises to be read by those on whom the method was to be applied. I show how reading I.13 and I.14 together, as Hobbes had intended, shows that Hobbes never changed his mind about rhetoric. (shrink)

A significant thread in Boris Hessen‟s iconic essay, The Social and Economic Roots of Newton’s Principia (1931), is his critique of Newton‟s involving God in his physics. Contra Newton, Hessen believes that nature does not need God in order to function properly. Hessen gives two, quite distinct, „internal‟ explanations of Newton‟s failure to see this. The first explanation is that Newton‟s failure is caused by his believing that motion is a mode instead of an attribute or essence of matter. The (...) second explanation is that Newton‟s failure is owed to his considering mechanical motion as the sole form of the motion of matter: Newton, in Hessen‟s view, did not realize that matter has many forms of motion which constantly transform into one another while conserving energy. In the present paper, I defend the thesis that none of these explanations can account for Newton‟s failure. Hessen‟s first explanation is problematic because even if Newton believed that motion is an attribute or essence of matter, he would still be obliged to involve God in physics. His second explanation fails too because he does not show exactly how the multiplicity and inter-transformation of forms of motion can account for nature‟s organizational structure. (shrink)

The article reflects on Heidegger’s “metaphysical” interpretation of Hegel’s Phenomenology of Spirit. This interpretation is driven by two theses Heidegger holds: (1) that the Phenomenology is a necessary part of Hegel’s “system of science” and (2) that the Phenomenology is metaphysics. These two theses contrast with Houlgate’s “epistemological” interpretation, which claims that the Phenomenology is not a necessary part of Hegel’s system of science and that it is not metaphysics. The article shows that while Heidegger has an argument that establishes, (...) contra Houlgate, that the Phenomenology is metaphysics, this very argument has consequences that undermine Heidegger’s thesis that the Phenomenology is a necessary part of Hegel’s system of science.

Extensive research has demonstrated that rs1360780, a common single nucleotide polymorphism within the FKBP5 gene, interacts with early-life stress in predicting psychopathology. Previous results suggest that carriers of the TT genotype of rs1360780 who were exposed to child abuse show differences in structure and functional activation of emotion-processing brain areas belonging to the salience network. Extending these findings on intermediate phenotypes of psychopathology, we examined if the interaction between rs1360780 and child abuse predicts resting-state functional connectivity (rsFC) between the amygdala (...) and other areas of the salience network. We analyzed data of young European adults from the general population (N = 774; mean age = 18.76 years) who took part in the IMAGEN study. In the absence of main effects of genotype and abuse, a significant interaction effect was observed for rsFC between the right centromedial amygdala and right posterior insula (p <.025, FWE-corrected), which was driven by stronger rsFC in TT allele carriers with a history of abuse. Our results suggest that the TT genotype of rs1360780 may render individuals with a history of abuse more vulnerable to functional changes in communication between brain areas processing emotions and bodily sensations, which could underlie or increase the risk for psychopathology.

Speight has recently raised the question, which he himself leaves unanswered, how naturalism relates to spirit in Hegel’s philosophy of art. ‘Naturalism’ denotes an explanation that invokes aspects of nature that are (allegedly) irreducible or resistant to thought. I call nature ‘stubborn’ insofar as it evinces resistance to its being formed by thought and hence to its being united with it. This paper argues that §§556, 558 and 560 of Hegel’s Encyclopedia answer Speight’s question by specifying three elements of nature (...) that, first, are present in art and, second, are resistant to thought. These are materiality, natural form, and genius. They exhibit nature’s stubbornness in art. This stubbornness, I argue, is what justifies Hegel’s claim that art is absolute spirt only implicitly (§556), which leads to the claim that art needs to be superseded by religion and philosophy. In this way, Speight’s question receives a precise answer. (shrink)

Bergson's views on time are supported by the time operator qualifying complex systems with a concept of time that is essentially difierent from the clock time used to register the events. Irreversibility, unpredictability, and innovation characterize complex systems in contrast with the reversibility, predictability and lack of novelties of the regular motions of integrable systems. The idea for this work came from our teacher Ilya Prigogine who pointed out repeatedly that the time operator actually incorporates Bergson's views on time. We (...) construct a time operator which incorporates Bergson's intuitive views on durations, indeterminism, innovations and irreversibility and the significance of events in terms of inno- vation and aging. In addition, Bergson emphasized that the signif- icance of durations depends on consciousness and memory, a discussion beyond the proposed time operator. Moreover we discuss the relation of Bergson's time with the internal time concepts of Husserl and Heidegger. (shrink)

Diarmuid Costello has recently argued that, contra received opinion, Kant’s aesthetics can accommodate conceptual art, as well as all other art. Costello offers an interpretation of Kant’s art theory that demands from all art a minimal structure involving three basic “players” and three basic “actions” corresponding to those “players.” The article takes issue with the “action” assigned by Costello’s Kant to the artwork’s recipient, namely that her imagination generates a multitude of playful thoughts deriving from or in any other way (...) relating to the concept or idea that the artist has instilled in the artwork and that the artwork transmits to the recipient. It is argued that the “proper” recipient of conceptual art may very well have a multitude of thoughts that are all irrelevant to the concept or idea the artist has instilled in the artwork, even if the artwork has transmitted that concept or idea to the recipient. This shows that Kant’s art theory, as presented by Costello, cannot accommodate conceptual art. I conclude by suggesting that either one of two amendments to the theory’s account of the recipient’s experience could enable it to accommodate conceptual art. (shrink)

In his "Hegel’s Phenomenology of Spirit," which includes his 1930-31 lectures on the "Phenomenology of Spirit," Heidegger states not only that Hegelian phenomenology “begins absolutely with the absolute,” but also that this phenomenological beginning is a necessary beginning of Hegel’s “system of science.” Although Heidegger acknowledges that the “proper” or “appropriate” beginning or “ground” of this system is the logical beginning (the beginning posited by Hegelian logic), he insists not only that there is also a second beginning of the system, (...) namely the one provided by the "Phenomenology of Spirit," but also that this beginning is necessary. Thus, Heidegger subscribes to the paradoxically-sounding thesis that Hegel’s system of science must have two beginnings. The present paper attempts, first, to flesh out this thesis (§§2-4), and, second, to uncover Heidegger’s argument for (or justification of) the claim that the phenomenological beginning is necessary to the Hegelian system of science (§§5-6).

In Plato’s Parmenides 132a-133b, the widely known Third Man Paradox is stated, which has special interest for the history of logical reasoning. It is important for philosophers because it is often thought to be a devastating argument to Plato’s theory of Forms. Some philosophers have even viewed Aristotle’s theory of predication and the categories as inspired by reflection on it [Owen 1966]. For the historians of logic it is attractive, because of the phenomenon of self-reference that involves. Bocheński denies any (...) possibility of correct logical reasoning before Aristotle. In particular, he flatly declares of Plato that “correct logic we find none in his work” [1951, 15]. In this line, many papers have been written that call attention to the violation of a metalogical principle – the type rules – because of the Third Man Paradox. The problem of interpretation of the paradox raised many discussions, since the 50’s, and the literature devoted to this topic is today enormous. Nevertheless, many points in Plato’s reasoning remain obscure. Hitherto, it is commonly believed that the paradox was simply stated by Plato in his "Parmenides", but not actually solved. Even more, it is believed that it is hardly possible for Plato to have suggested a solution, because he confused the categories of substance and attribute. B. Russell has also argued that Plato violates in his arguments the restrictions imposed on language by the theory of logical types. This view is encouraged by the linguistic difficulties, which Plato has faced in his attempt to formulate an ontology of abstract entities, i.e. that in Greek language abstract and concrete terms are formally indistinguishable [Kneales 1984]. In this paper, we analyse the logical structure of the argument in an attempt to give a systematic consistent reconstruction of the text appealing to methods and concepts of modern logic and semantics. Already in 1954 G. Vlastos had noted in his seminal paper “The ‘Third Man’ Argument in the Parmenides” that “if any progress … is to be made at this juncture it must come from some advance in understanding the logical structure of the Argument”. Accordingly, our analysis is primarily focused on the line of logical reasoning, rather than the metaphysical underpinnings and philosophical implications of the paradox for Plato’s theory of Forms. We divide the Platonic text into three parts, presenting apparent thematic coherence: a) Formulation of the Third Man Paradox (132a-132b). The central issue of this part is a step-like generation of Forms that can continue ad infinitum. b) Discussion of the paradoxical situation (132b-c), by passing to the use of terminology echoing Eleatic philosophy. The concept of “thought” and the underlying semantics of Eleatic origin are central in this passage. c) Solution of the paradox (132d-133a). In our view, this part contains not only a resemblance regress, as most interpretators con-sider, but also the solution of the paradox by the introduction of a sound definition of the concept of “similarity”. We should note that the name ‘Third Man Paradox’ never occurs in Plato, who, strictly speaking, formulates a ‘Third Large Paradox’. The name ‘Third Man Paradox’ appears in the works of Aristotle and the commentators of the Peripatetic tradition. Later commentators have identified Aristotle’s Third Man with Plato’s Third Large Argument. In our paper, we also examine other testimonies about the Third Man Paradox found in the works of commentators in order to illuminate the logical structure of the argument. Although the vocabulary used in these versions is different, they do not affect its logical structure, but rather reveal different understandings by the ancient authors. These testimonies are divided into two main categories: those met in Neo-Platonic authors, notably in Proclus’ "Commentary on Plato’s Parmenides", and the versions of the Third Man Paradox found in texts of the Peripatetic tradition (Eudemus, Aristotle, Alexander). From our discussion, it becomes clear that the approaches to the paradox by the various scholars of antiquity are different, depending also on their participation in the one or the other campus of philosophical thought. We show that the Peripatetic authors are aware of the source of the paradox. However, the first scholar of antiquity who explicitly ascribes a solution to Plato seems to be Proclus. (shrink)

A preliminary investigation into the orientation of twelve Greek Byzantine churches towards the east is made in relation to the day of sunrise. Measurements were carried out using magnetic compass with inclinometer and GPS while declination corrections included a) local magnetic declination and b) refraction. The position of sunrise in the horizon as well as during morning hours was computed with in-house software. Accounting for the differences between Gregorian and Julian calendars, orientation of the nave towards spring and/or autumn, i. (...) e. around the two equinoxes, was found for most churches. Orientations toward the summer solstice and the name day of the saint were also found. (shrink)

The lack of specific arithmetical axioms in Book VII has puzzled historians of mathematics. It is hardly possible in our view to ascribe to the Greeks a conscious undertaking to axiomatize arithmetic. The view that associates the beginnings of the axiomatization of arithmetic with the works of Grassman [1861], Dedekind [1888] and Peano [1889] seems to be more plausible. In this connection a number of interesting historical problems have been raised, for instance, why arithmetic was axiomatized so late. This question (...) was first posed and quite conclusively answered by Yanovskaja [1956]. Her major and quite conclusive argument was that “algorithms in arithmetic have absolute character, while in geometry we have to do with reducibility algorithms”. In this paper we are going to draw attention on certain peculiarities of the construction of the arithmetical Books of Euclid’s "Elements" and show that Euclidean arithmetic is constructed by effective procedures. In spite of the use of inference by reductio ad absurdum and methods equivalent to mathematical induction, Euclidean arithmetic retains its finitary character. It is not full arithmetic, but a finitary fragment of classical arithmetic, and thereby there was not any internal reason for its axiomatization. (shrink)

The present article reports several applied experiments in the generation of aesthetic forms from algorithms and data. In these experiments algorithms and data are the driving morphogenetic force to such an extent that the role of the human creator must be reexamined case-by-case. Artists that program the graphics or sound generating algorithms may in turn be said to be programmed perceptually by the resulting artworks, in the sense that they must adapt their perception in a conscious or involuntary effort to (...) detect or project meaning in their form. While forms generated by algorithms or data are to a large extent unpredictable, an intimate relationship between programmer, performer/listener/viewer and the piece is created through instinctive, empirical familiarity with the tools and the creative process, which is afforded by the immediate and highly interactive nature of the frameworks employed. A simple iterative algorithm that produces a novel kind of chaotic geometric shapes is presented. Examples of an application of Paul Klee’s principles of visual form in programming interactive audio-visual dance performance are given. These principles are directly derived from the language-based metaphor of active, medial and passive voice. Finally, ongoing experiments in letting language structures emerge from data derived from a sound database are presented. (shrink)

The paper examines Andrei A. Markov’s critical attitude towards L.E.J. Brouwer’s intuitionism, as is expressed in his endnotes to the Russian translation of Heyting’s Intuitionism, published in Moscow in 1965. It is argued that Markov’s algorithmic approach was shaped under the impact of the mathematical style and values prevailing in the Petersburg mathematical school, which is characterized by the proclaimed primacy of applications and the search for rigor and effective solutions.

Michael Tomasello ( 2016 ) prominently defends the view that there are uniquely human capacities required for shared intentions, therefore great apes do not share intentions. I show that these uniquely human capacities for abstraction are not necessary for shared intentionality. Excluding great apes from shared intentions because they lack certain capacities for abstraction assumes a specific interpretation of shared intentionality, which I call the Roleplaying Model. I undermine the necessity of abstraction for shared intentionality by presenting an alternative model (...) of shared intentionality, which I call the Normative Model. It is a modification of Margaret Gilbert’s ( 2013 ) Plural Subject theory, which I modify such that it is, in principle, compatible with nonhuman shared intentionality. To do this, I substitute Gilbert’s account of obligation for Kristin Andrews’ ( 2020 ) account of animal social norms. In this Normative Model, uniquely human capacities for abstraction are not required for shared intentionality. By undermining the necessity of uniquely human abstraction, I make cases of prima-facie cooperation in chimpanzees plausible instances of shared intentionality. The Roleplaying Model’s denial of nonhuman shared intentionality creates a problem insofar as apparent shared intentional activity cannot be fully analyzed. The Normative Model resolves this problem.

In a Mental Imagery Brain-Computer Interface the user has to perform a specific mental task that generates electroencephalography components, which can be translated in commands to control a BCI system. The development of a high-performance MI-BCI requires a long training, lasting several weeks or months, in order to improve the ability of the user to manage his/her mental tasks. This works aims to present the design of a MI-BCI combining mental imaginary and cognitive tasks for a severely motor impaired user, (...) involved in the BCI race of the Cybathlon event, a competition of people with severe motor disability. In the BCI-race, the user becomes a pilot in a virtual race game against up to three other pilots, in which each pilot has to control his/her virtual car by his/her mental tasks. We present all the procedures followed to realize an effective MI-BCI, from the user's first contact with a BCI technology to actually controlling a video-game through her EEG. We defined a multi-stage user-centered training protocol in order to successfully control a BCI, even in a stressful situation, such as that of a competition. We put a specific focus on the human aspects that influenced the long training phase of the system and the participation to the competition. (shrink)

Plato's Laches, the dialogue devoted to the discovery of courage, is generally considered a failure, as the interlocutors' various definitions ultimately prove insufficient. Laches, however, notes that a definition of this kind can only be assessed by considering whether the speaker's words and deeds are in harmony. In fact he goes one step further, and admits that deeds are far more persuasive than words. He therefore declares that he is willing to let Socrates, whose deeds on the battlefield speak volumes, (...) say whatever he pleases. Although himself content to deal with words, Socrates is well aware that, as far as others are concerned, Laches is right. During his defence, for example, Socrates proposes to convince the jury that he is not afraid of death by offering them 'great proofs'; not words, but what they value, namely deeds. On his final day, having undergone a lengthy and complex attempt to persuade his friends that death is nothing to be afraid of, Socrates leaves them with a deed attuned to his word, and thus becomes, in Nietzsche's words, 'the emblem . . . above the entrance gate of science'.

How do social movements respond to the ecological crisis? In this paper, we reframe social movements as 'more-than-social movements' to highlight the fact that many contemporary mobilisations do much more than target recognised social institutions and political governance; indeed, they are practically transforming eco-societies with and within both the human and the nonhuman world. What constitutes the core of more-than-social movements' action is the capacity to set up alternative ecologies of existence, or 'alterontologies', as we call them in the paper. (...) In what follows, we engage with the imaginaries and practices of agroecology, AIDS treatment activism and permaculture in order to rethink what autonomy and justice might look like in the context of today's ecological crisis.

Book I of Plato's Republic is unusually eventful, yet one episode stands out: Socrates' exchange with Thrasymachus. Thrasymachus' challenge raises a hurdle that Socrates must overcome if he is to convince the audience -- both those present and those reading his account of the discussion -- that, despite plenty of evidence to the contrary, might does not make right. That challenge, however, puts Socrates in the awkward position of having to prove Thrasymachus wrong without appearing to overpower him in the (...) argument and thereby inadvertently proving his opponent's point. Socrates thus allows Thrasymachus to take the reins of the inquiry, only to overthrow and replace him. Once in charge, however, Socrates admits that his own rule over the inquiry ended in an injustice. Socrates' surprising admission signals that his demonstration was necessary to clear the ground for the discovery of justice. His power struggle with Thrasymachus thus renders Book I an indispensable part of the Republic, and foreshadows the interlocutors' troubling realization that justice and power are ultimately impossible to reconcile fully.
