It is a matter of fact that Europe is facing more and more crucial challenges regarding health and social care due to the demographic change and the current economic context. The recent COVID-19 pandemic has stressed this situation even further, thus highlighting the need for taking action. Active and Assisted Living technologies come as a viable approach to help facing these challenges, thanks to the high potential they have in enabling remote care and support. Broadly speaking, AAL can be referred (...) to as the use of innovative and advanced Information and Communication Technologies to create supportive, inclusive and empowering applications and environments that enable older, impaired or frail people to live independently and stay active longer in society. AAL capitalizes on the growing pervasiveness and effectiveness of sensing and computing facilities to supply the persons in need with smart assistance, by responding to their necessities of autonomy, independence, comfort, security and safety. The application scenarios addressed by AAL are complex, due to the inherent heterogeneity of the end-user population, their living arrangements, and their physical conditions or impairment. Despite aiming at diverse goals, AAL systems should share some common characteristics. They are designed to provide support in daily life in an invisible, unobtrusive and user-friendly manner. Moreover, they are conceived to be intelligent, to be able to learn and adapt to the requirements and requests of the assisted people, and to synchronise with their specific needs. Nevertheless, to ensure the uptake of AAL in society, potential users must be willing to use AAL applications and to integrate them in their daily environments and lives. In this respect, video- and audio-based AAL applications have several advantages, in terms of unobtrusiveness and information richness. Indeed, cameras and microphones are far less obtrusive with respect to the hindrance other wearable sensors may cause to one’s activities. In addition, a single camera placed in a room can record most of the activities performed in the room, thus replacing many other non-visual sensors. Currently, video-based applications are effective in recognising and monitoring the activities, the movements, and the overall conditions of the assisted individuals as well as to assess their vital parameters. Similarly, audio sensors have the potential to become one of the most important modalities for interaction with AAL systems, as they can have a large range of sensing, do not require physical presence at a particular location and are physically intangible. Moreover, relevant information about individuals’ activities and health status can derive from processing audio signals. Nevertheless, as the other side of the coin, cameras and microphones are often perceived as the most intrusive technologies from the viewpoint of the privacy of the monitored individuals. This is due to the richness of the information these technologies convey and the intimate setting where they may be deployed. Solutions able to ensure privacy preservation by context and by design, as well as to ensure high legal and ethical standards are in high demand. After the review of the current state of play and the discussion in GoodBrother, we may claim that the first solutions in this direction are starting to appear in the literature. A multidisciplinary debate among experts and stakeholders is paving the way towards AAL ensuring ergonomics, usability, acceptance and privacy preservation. The DIANA, PAAL, and VisuAAL projects are examples of this fresh approach. This report provides the reader with a review of the most recent advances in audio- and video-based monitoring technologies for AAL. It has been drafted as a collective effort of WG3 to supply an introduction to AAL, its evolution over time and its main functional and technological underpinnings. In this respect, the report contributes to the field with the outline of a new generation of ethical-aware AAL technologies and a proposal for a novel comprehensive taxonomy of AAL systems and applications. Moreover, the report allows non-technical readers to gather an overview of the main components of an AAL system and how these function and interact with the end-users. The report illustrates the state of the art of the most successful AAL applications and functions based on audio and video data, namely lifelogging and self-monitoring, remote monitoring of vital signs, emotional state recognition, food intake monitoring, activity and behaviour recognition, activity and personal assistance, gesture recognition, fall detection and prevention, mobility assessment and frailty recognition, and cognitive and motor rehabilitation. For these application scenarios, the report illustrates the state of play in terms of scientific advances, available products and research project. The open challenges are also highlighted. The report ends with an overview of the challenges, the hindrances and the opportunities posed by the uptake in real world settings of AAL technologies. In this respect, the report illustrates the current procedural and technological approaches to cope with acceptability, usability and trust in the AAL technology, by surveying strategies and approaches to co-design, to privacy preservation in video and audio data, to transparency and explainability in data processing, and to data transmission and communication. User acceptance and ethical considerations are also debated. Finally, the potentials coming from the silver economy are overviewed. (shrink)

Computer and communication technologies created new modes of creating and sharing arts. In this paper, we apply ‘diffusion of innovation’ theory to investigate how artistic content travels in an online social network site called deviantArt, a site designed for sharing user-generated artworks. We first define what innovation corresponds to in such a context, and then discuss how it can be measured with the help of network, image and text analysis methods. We propose to use user-shared resources as relatively easy targets (...) of tracking innovation. (shrink)

The concept of value is so wide that could be considered as synonymous with human life and existence. The human being is engaged in the evaluations of being by doing every act. Life is a value that even its ascetic denial is a kind of valuation. When the human being enters the world, in fact he enters a pre-valued world and many values weighed upon him. To what extent is man capable of emancipating from pre-existing values and to what extent (...) can he succeed in creating value? The complex world today is very similar to the mythical world in which the blind and deaf valuing forces have overwhelmed and conquered human choices. It is here that human choices show a confusing and algebraic procedure, and freedom is as s chain that human being wrap around himself. (shrink)

The paper deals with the study of the existence of weak positive solutions for a new class of the system of elliptic differential equations with respect to the symmetry conditions and the right hand side which has been defined as multiplication of two separate functions by using the sub-supersolutions method.

Fractional calculus is nowadays an efficient tool in modelling many interesting nonlinear phenomena. This study investigates, in a novel way, the Ulam–Hyers and Ulam–Hyers–Rassias stability of differential equations with general conformable derivative. In our analysis, we employ some version of Banach fixed-point theory. In this way, we generalize several earlier interesting results. Two examples are given at the end to illustrate our results.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Islam: Religion, History, and CivilizationZain AliIslam: Religion, History, and Civilization. By Seyyed Hossein Nasr. San Francisco: Harper San Francisco, 2003. Pp. 224. Paper $9.71."Islam," writes Seyyed Hossein Nasr, "is like a vast tapestry," and in his book Islam: Religion, History, and Civilization he aims to survey the masterpiece that is Islam. The present work is part of a trilogy including Ideal and Realities of Islam and The Heart (...) of Islam. Nasr states that the common theme in the trilogy "is the universalist perspective and respect for other religions" (p. xxiv). In addition, Nasr clarifies that his approach, as with all of his Islamic writings, is to write from an Islamic perspective, which he terms "traditional Islam" (p. xxiii). Nasr stands opposed to either the secular modernist or fundamentalist perspectives, both of which he regards as forms of extremism.This book, initially published as part of Our Religions, edited by A. Sharma, is significantly revised and includes a new introduction and bibliography. It can best be described as a primer on Islam, consisting of eight chapters that focus on a variety of pertinent themes.Chapter 1 deals with the self-understanding of Islam and the Islamic world. Islam, Nasr notes, sees itself as a return to the primordial faith of humanity, a faith that affirms the unity and oneness of God. This chapter also presents an overview [End Page 495] of the various ethnic and cultural groupings within the Muslim world, and charts the spread and demographic growth of Islam.Chapter 2 introduces the notion of al-din, an Arabic term that corresponds closely to the word "religion." Nasr contrasts the two words, where religion means "to bind" while al-din means "debt" (p. 25). Thus, religion, as framed by Islam, involves the notion of debt, in particular humanity's debt to the Divine. The chapter also discusses the significance of the Qur'an and Muhammad as the messenger of God.Chapter 3 begins with an exposition of the nature of Divinity, which is at the heart of Islamic doctrine. As Nasr explains, the Divine is understood as being "at once the Absolute, the Infinite, and the Perfect Good" (p. 59). The remainder of the chapter deals with various Islamic doctrines and beliefs, including prophecy and revelation, human nature, the Qura'nic view of men and women, and eschatology.Chapter 4 deals with the content, codification, and schools of Shariah, the Divine Law of Islam. There is also an interesting discussion of Sufism, which Nasr claims "is like the heart of the body of Islam" (p. 81). Controversially, Nasr claims that "the spread of Islam outside of the Arab and Persian worlds up to the present day has been mostly through Sufism" (p. 87).Chapter 5 delves into the central pillars of Islam, which accompany the belief in God and in Muhammad as the messenger of God. The pillars are salah (canonical prayer), sawn (fasting), hajj (pilgrimage), and zakah (religious tax or charity). Associated with these pillars is the notion of jihad, and here Nasr writes, "jihad... is usually mistranslated into English as 'holy war,' but literally means 'exertion' or 'effort' in the path of God" (p. 91). Also covered are the topics of family, ethics, and economic and political institutions.Chapter 6 presents the historical evolution of Islam beginning with the migration of Muhammad to Medina, and the events leading to the divide between Sunnis and Shiites.Chapter 7 discusses the early Islamic community, who found themselves in the "throes of disputes over such issues as whether human beings are saved by faith or works, whether there is freewill or determinism, and questions concerning the sacred text as the Word of God" (p. 154). Nasr then explores the various schools of theology and philosophy that arose in order to address these questions of faith.Chapter 8, the final chapter of the book, attempts to evaluate the place of Islam in the contemporary world. Nasr concludes by noting that despite the challenges of secular modernism and fundamentalism the vast majority of Muslims remain committed to the truth of Islam, and bear witness to the Oneness of God and the Oneness of humanity.The one quibble...

The book you hold in your hands is the outcome of the "ISCS 2013: Interdisciplinary Symposium on Complex Systems" held at the historical capital of Bohemia as a continuation of our series of symposia in the science of complex systems. Prague, one of the most beautiful European cities, has its own beautiful genius loci. Here, a great number of important discoveries were made and many important scientists spent fruitful and creative years to leave unforgettable traces. The perhaps most significant period (...) was the time of Rudolf II who was a great supporter of the art and the science and attracted a great number of prominent minds to Prague. This trend would continue. Tycho Brahe, Niels Henrik Abel, Johannes Kepler, Bernard Bolzano, August Cauchy Christian Doppler, Ernst Mach, Albert Einstein and many others followed developing fundamental mathematical and physical theories or expanding them. Thus in the beginning of the 17th century, Kepler formulated here the first two of his three laws of planetary motion on the basis of Tycho Brahe’s observations. In the 19th century, nowhere differentiable continuous functions (of a fractal character) were constructed here by Bolzano along with a treatise on infinite sets, titled “Paradoxes of Infinity” (1851). Weierstrass would later publish a similar function in 1872. In 1842, Doppler as a professor of mathematics at the Technical University of Prague here first lectured about a physical effect to bear his name later. And the epoch-making physicist Albert Einstein – while being a chaired professor of theoretical physics at the German University of Prague – arrived at the decisive steps of his later finished theory of general relativity during the years 1911–1912. In Prague, also many famous philosophers and writers accomplished their works; for instance, playwright arel ape coined the word "robot" in Prague (“robot” comes from the Czech word “robota” which means “forced labor”).

It is well-known that Ibn al-Salāh al-Shahrazūrī (d. 643/1245) has an important place in the field of hadith methodology. In this context, it is possible to see Ibn-al Salah’s influence in a large proportion of the hadith terminology. The fact that the term ḥasan was not substantially included in the hadith method studies before Ibn-al Salah and that this concept became widely known in the field after him led to study the contributions of al Salah on the (...) subject of ḥasan hadith and in this regard, his effect on the term ḥasan. As result it was found that authorities such as Shāfiʿī (d. 204/820), ʿAlī b. al-Madīnī (d. 234/848-49), Ahmad b. Hanbal (d. 241/855) used the concept of ḥasan in various meanings before al-Tirmidhī (d. 279/892) who, according to general acceptance, made the term ḥasan famous for its terminological use. However, it is possible to say that ʿAlī b. al-Madīnī was the first to use the terminological meaning of the concept ḥasan. Actually, the fact that Shafii’ used the term ḥasan isnād for an authentic hadith that al-Bukhārī (d. 256/870) and Muslim b. Ḥajjāj (d. 261/875) would later unanimously narrate, and Ahmad b. Hanbal used ḥasan as gharib, is evidence for the unsystematic use of the term in the early periods. Even though, thanks to al-Tirmidhī, an important place was opened for the concept in riwāya literature, there was no serious mention of the term in later hadith methodology. Therefore, it has been seen that hadith scholars considered the term ḥasan within the scope of ṣaḥīḥ or ḍaʻīf hadith, since they accepted the term as an intermediate concept, and for this reason they did not include the term ḥasan among the subjects of hadith methodology until Ibn al-Salāh. An examination of the argument, that one can act upon a ḍaʻīf hadith, would show that ḥasan hadith might have been interpreted within the scope of ḍaʻīf hadith. On the other hand, the fact that some scholars such as Mughulṭāy b. Qilīj (d. 762/1361) state that a hadith would be called ṣaḥīḥ if it is maqbūl with any presumption, and that there is no point in calling such a hadith ḥasan shows that the ḥasan hadith is considered within the scope of ṣaḥīḥ hadith. The fact that hadith methodology scholars did not mention ḥasan hadith before Ibn al-Salāh stems from the ambiguity of the subject. Contrary to his predecessors, Ibn al-Salāh tried to save the term ḥasan from its ambiguity by combining the different specifications put forward by al-Tirmidhī, al-Khaṭṭābī (d. 388/998), and Ibn al-Jawzī (d. 597/1201). The specifications and interpretations of the term presented by Ibn al-Salāh via his meticulous efforts, have also been adopted by his successors. The term ḥasan hadith has gained an important place in the literature of hadith methodology thanks to the views and definitions built on the descriptions and interpretations of Ibn al-Salāh. In this context, while there are those who agree with Ibn al-Salāh’s descriptions and evaluations of the term, there are also those who criticize his remarks on the subject. However, it has been seen that those who criticize Ibn al-Salāh, along with those who follow him, criticized him by following the path drawn by Ibn al-Salāh. Based on this and similar situations, it was concluded that not only the descriptions and comments that Ibn al-Salāh made, but also his style and methods of handling the subject gave direction to the studies on hadith methodology. In addition, it has been observed that the most compact description of the term ḥasan is put forward by Ibn Hajar and today’s studies are predicated on his description. Within this framework, after emphasizing that there are four degrees of maqbūl hadiths, Ibn Hajar defined the two fields, which were covered by two different descriptions of Ibn al-Salāh, as ḥasan li-zatih and lighairih by Ibn al-Ḥajar. (d. 852/1449) By doing so Ibn al-Ḥajar gave the final shape to the ḥasan hadith terms. He also captured the fundamental point where ḥasan hadith differs from the ṣaḥīḥ hadith because the basic point in question, which was not directly stated before, is a slight flaw in the narrator’s grip. At the end of the study, it was concluded that -as al-Dhahabi (d. 748/1348) also stated- it does not seem possible to determine a comprehensive rule that gathers ḥasan hadiths under a single description. Considering the historical context of the term ḥasan, it has been observed that the most effective description of the ḥasan hadith are the terms ḥasan li-zatih and ḥasan lighairih, which were put forward by Ibn Hajar by transforming the dual division mentioned by Ibn al-Salāh into a more understandable form.

The political theory of the property-owning democracy can be seen as a way of overcoming the ideological conflict between individualism and collectivism. Rawls offers the contemporary reference-point for this theory. Rawls contrasted the ideal-type of the property-owning democracy with the ideal-type of a capitalist welfare state. However, the terms of that contrast are not well drawn and raise a number of questions, in particular regarding Rawls’s a priori specification of the welfare state. An inductively derived specification of ideal-typical welfare states (...) suggests that horizontal redistribution, in line with the principle of social savings, is more important than vertical redistribution. Rawls’s preference for a social dividend or negative income tax scheme can be contrasted with the use of social insurance, but the latter has a claim to instantiate Rawlsian ideals better than a social dividend. There is a potential problem with the pre-emption of private savings in the welfare state, but this turns out not to be troublesome empirically or conceptually. The irony of the discussion is that those who have interpreted Rawlsian theory as justifying the welfare state have the better of the argument, despite Rawls’s own views. (shrink)

It is known that when Boabdil, the last of the Abencerrages, left Granada definitively, driven out by the reconquest, he gave a final look at his admirable city and, at that precise moment, sighed deeply. That sigh—el suspiro del Moro—has come down to us through history and after us will no doubt touch and disturb the sensibility of our descendants until the end of time. However, is it really a matter of Boabdil‘s sigh only, or is it the one, coming (...) from Adam, of those who have lost Paradise? Here, Boabdil seems to be one relay among others of that lament issuing from the depths of the species and rising, as regret and never-ceasing nostalgia, to the easily-agitated surface of our ocean of domesticity. Since that first garden, we have been the unloved children of this regret and this nostalgia. The angel with the fiery sword changes nothing: he does not have our memory that, alone, makes us every day a little less original and, in doing so, expels us, making us a little more defenseless than we were when we came out of the void. To remember is obviously to lose oneself, and we are at every moment in this vertiginous situation. As Heidegger said, to remember is to contemplate oblivion. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Evolution of Pragmatism in India: Ambedkar, Dewey, and the Rhetoric of Reconstruction by Scott R. StroudAlbert R. SpencerBy Scott R. StroudThe Evolution of Pragmatism in India: Ambedkar, Dewey, and the Rhetoric of Reconstruction Chicago and London: The University of Chicago Press, 2023. 302 pp., incl. indexMore scholarly attention needs to be paid to the mutual influences between Asian and American thought, especially with regards to the development, (...) legacy, and future of pragmatism. Fortunately, there have been several notable attempts. Throughout his works, Richard Shusterman frequently incorporates the perspectives of various East Asian philosophies into his articulation of somaesthetics. Multiple scholars have explored John Dewey’s lectures in China and their political and educational impact, such as Jessica Ching-Sze Wang’s John Dewey in China or The Democracy of the Dead by Roger T. Ames and David L. Hall. Still others have highlighted the influence of Indian thought on pragmatism’s forerunners, such as American Philosophy Before Pragmatism (Goodman 2015), American Pragmatism: An Introduction (Spencer 2020), and The Ethics of Oneness (Engles 2021). Perhaps the most interesting inquiries into this influence can be found in a special volume of The Journal of Aesthetic Education (Vol. 43, No. 1) where multiple scholars discuss pragmatism’s connections and comparisons to The Bhagavad Gita, Confucianism, and Taoism. Among these scholars is Scott Stroud whose most recent publication The Evolution of Pragmatism in India (2023) represents the culmination of nearly two decades of research on the subject with special attention to the continuities between pragmatism and Indian thought. In it, he meticulously explores the influence of John Dewey on one of his students, Bhimrao Ambedkar (1891–1956), who was a transformative figure in the founding of the nascent Republic of India. The result is a work of scholarship that shows the global relevance of pragmatism in the 20th Century, [End Page 456] introduces the fascinating philosophy of Ambedkar to a non-Indian audience, and provides an entry for further scholarship on this profound thinker and activist.Bhimrao Ambedkar was a critical figure in the birth of modern India. Born an “untouchable” due to the rigid caste system, he tirelessly advocated for the right of Dalits (“crushed” or “untouchables”). By the mid-20th century, he had greatly influenced Indian politics, safeguarded the interests of the oppressed, and played a key role in drafting the Indian Constitution. Separate to his role as a statesman, Ambedkar promoted Buddhism in the 1950s as an escape from caste oppression, culminating in his publication, The Buddha and His Dhamma (1957). While his name is less familiar outside of India, he was voted the “Greatest Indian” in a 2012 poll due to his profound impact on the nation’s post-independence development. These accomplishments were supported by an extensive education, but unlike most subjects of the British Empire, Ambedkar also studied in the United States. Stroud initiates his study by focusing on this formative period, specifically his time at Columbia University and the influence of the philosopher and psychologist John Dewey. While their relationship has been acknowledged, Stroud is the first to explore this relationship in depth and he not only reconstructs the influence of Dewey on Ambedkar’s Navayana Pragmatism but illuminates the ways that Ambedkar integrated, modified, and even resisted Dewey’s pragmatism.Stroud masterfully builds his reconstruction of this synergy between Dewey’s pragmatism and Ambedkar’s philosophy not out of ephemeral conjecture or pithy textual evidence, but through painstaking, detailed, and exhaustive scholarship. He draws on comparative evidence in their major and minor works, their private correspondence, interviews of Ambedekar’s cohort at Columbia, Dewey’s voluminous lecture notes, and even the marginalia and notecards found between the pages of Ambedkar’s pragmatism bookshelf. Indeed, I often found myself pleasantly distracted as I imagined Stroud’s academic pilgrimage throughout India, Columbia University, and the Center for Dewey Studies to find every scrap of relevant information. In our age of instant information and digital archives, it is refreshing and inspiring to encounter a scholar still willing to trek across the globe for answers to his inquiries. Despite his passion to uncover the influence of Dewey on Ambedekar, Stroud never reduces the... (shrink)

We study some representations of real numbers. We compare these representations, on the one hand from the viewpoint of recursive functionals, and of complexity on the other hand.The impossibility of obtaining some functions as recursive functionals is, in general, easy. This impossibility may often be explicited in terms of complexity: - existence of a sequence of low complexity whose image is not a recursive sequence, - existence of objects of low complexity but whose images have arbitrarily high time- complexity .Moreover, (...) some representations of real numbers that are equivalent from the viewpoint of recursive functionals, are very distinct from the viewpoint of complexity.We make a particular study of representations via continued fractions . We precise exactly what part of information available in the x's dfc is equivalent to the information available in its Dedekinds cut. We show that the sum of two reals whose dfcs are polynomial-time computable may be a real whose dfc has time complexity arbitrarily high.This work confirms that the unique representation of real numbers suitable for the ordinary calculus is via explicit Cauchy sequences of rationals.RésuméNous étudions différentes manières de présenter les nombres réels. Nous comparons ces présentations du point de vue des fonctionnelles récursives d'une part, et de celui des classes de complexité d'autre part.L'impossibilité d'obtenir certaines fonctions sous forme de fonctionnelles récursives est en général facile à établir. Cette impossiblité peut souvent être explicitée en termes de complexité: - il existe une suite de faible complexité dont l'image est une suite non récursive, - il existe des objets de faible complexité mais dont les images sont des objets de complexité arbitrairement grande .En outre, certaines présentations des réels équivalentes du point de vue des fonctionnelles récursives se distinguent nettement du point de vue de la complexité.Nous faisons une étude particulière concernant les développements en fraction continue . Nous précisions exactement quelle est la partie de l'information disponible dans le dfc d'un réel x qui équivaut à l'information disponible dans sa coupure de Dedekind. Nous montrons également que la somme de deux réels dont le dfc est calculable en temps polynomial peut être un réel dont le dfc est de complexité arbitrairement grande.Ce travail confirme que seule une présentation des réels via des suites de rationnels explicitement de Cauchy est adaptée aux calculs avec les réels.

This paper deals with the mystical experiences in Virginia Woolf’s artistic creation. Woolf denies any form of modernism that cannot transcend reality. There are moments, where reality is never what it is but a vision — a perspective — whose meaning is beyond the graspable. Reality, thus, becomes un-reality — a halo, and the artist becomes a contemplator — a devotee to such visionary manifestation. Virginia Woolf does not make an exception to this rule. She is par excellence a mystic. (...) The artistic design of her novels, mainly, To the Lighthouse, is of transcendental dimension. Both, Mrs Ramsay’s and Lily Briscoe’s perceptions of life are beyond the palpable: their selves merge within a process of sublimation comparable to that of mysticism. In other words, art (mainly fiction) becomes a process of change from the factual to the transmutable. (shrink)

This paper deals with the study of the existence of weak positive solutions for sublinear Kirchhoff elliptic systems with zero Dirichlet boundary condition in bounded domainΩ⊂ℝNby using the subsuper solutions method.

The aim of this contribution is to examine and unveil the Augustinian time process and self-examination in Virginia Woolf’s “To the Lighthouse.” The latter is a successful (re)presentation of the interrelation between human consciousness and time “control”. The self cannot be defined without time dimension. Woolf seems to confirm that time is more interior than exterior and is an essential part of human being: it is through it that human being is felt as a part of the world. There are (...) some powerful statements of her characters that show strange similarities to Augustine’s doctrine of time, memory and existence. This triad characterizes his works, mainly “Confessions.” Woolf’s characters are so contemplative. We find them looking outward in order to discover their inside. The internal and the external are the focus of time knowledge and self-discovery. They are dialogically interrelated and define one another. The self is an ever “IS” within the presentness of the present: the “was” (past) is only a memory (“the no-longer”) and the “will be” (future) is only the “not-yet” that has to come in order to become a present. In Augustine’s doctrine, the past and the future do not exist because they are absent in the present. Yet, their only existence is the present – the NOW. Consciousness preserves one’s past within itself. The individual meets and examines himself through consciousness. Mrs. Ramsay in “To the Lighthouse” experiments these dimensions and tries to define herself through time. (shrink)

Does translation of the literary text really need a theory? If yes which one among so many, which complicate more than simplify the matter? Which strategy do we adopt to at least communicate something of the original to a target reader, who does not know anything of the source language? The key problem is the meaning. Is it really grasped? If yes, is it of the text, or of the author, or of the reader? Meaning is not restricted to linguistic (...) parameters; it is more cognitive and essentially based on the interpreter’s own world knowledge. The text is not only a product but essentially an on-going process of meaning. Though it has precise time and space when produced, it is, nonetheless, timeless and spaceless. When we animate it, through reading, it becomes a text within the scope of a new space and a new time. That is, the meaning in the process of translation becomes anew. The text is autonomous and its autonomy makes it have its own specificity and existence. And so, the meaning in/of the text is ever-changing: there is no one meaning in/of the text, as there is no one reader of the text. (shrink)

We give a polynomial time controlled version of a theorem of M. Hall: every real number can be written as the sum of two irrational numbers whose developments into a continued fraction contain only 1, 2, 3 or 4.

Cet essai relate le cheminement, à travers la Bible, d'une pensée libre, en opposition à la "rétention honteuse, chez les musulmans, pour aller à la découverte de la Torah et des Evangiles" (Youssef Seddik), et à leur "indifférence pour ce qui relève de la connaissance du monde juif, de son passé ou de sa pensée" (Victor Malka). En relevant, à travers l'épopée du peuple "inventeur du dieu unique", les codes qui fondent la morale juive, l'auteur a eu le sentiment de (...) découvrir en YHWH un "Grand Ordonnateur de feuilles de route". Une route rigoureusement balisée, avec ses bornes et ses "haies" de protection - qu'en hébreu on appelle des syagim. Ainsi, après quatre années passées à glaner sur les "terres" du judaïsme biblique, telle Ruth glanant sur les terres de Booz, après avoir étudié plus de cent textes juifs, anciens et contemporains, l'auteur interroge ici le rapport du Juif à son prochain (parent, voisin, étranger, allié ou ennemi). Une découverte. (shrink)

À travers le présent entretien, Salah Stétié, écrivain au carrefour d’au moins deux traditions culturelles, envisage son rapport singulier à la question de l’entre-deux. Il évoque en particulier le lien très étroit qui l’unit aux civilisations de la Méditerranée ; la question de l’intervalle l’amène à parler du sens de son écriture poétique, de son rapport à la langue et à la traduction. Plus surprenant sans doute est le contexte premier qu’il donne à son exploration poétique, selon une inspiration (...) très orientale : une physique spirituelle de l’énergie — de la danse de l’énergie, au centre de laquelle le poète se tient, à « la source des vertiges ». C’est une entité quasi impersonnelle et insituable qui écrit, à la croisée des dimensions mentales, spirituelles et verbales — et d’un inconscient qui serait beaucoup plus large que le personnel. Cependant, pour Salah Stétié, le poète, loin de ne résider nulle part, développe une « citoyenneté surplombante » qui lui permet de circuler dans toute l’étendue du réel, de l’embrasser dans son ensemble et d’en témoigner sans exclusive. Through this interview, Salah Stétié, writer in the crossroads of at least two cultural traditions, envisages his singular relationship in the question of the in-between. He evokes in particular the very narrow link which unites him with the civilizations of the Mediterranean Sea ; the question of the interval leads him to speak about the sense of its poetic writing, about its relationship in the language and in the translation. More surprising doubtless is the first context which he gives to his poetic exploration, according to a very oriental inspiration: a spiritual physics of the energy—of the dance of the energy, in the center of which the poet stands, near to “the spring of the dizzinesses”. It is a quasi-impersonal and insituable entity who writes, between the mental, spiritual and verbal dimensions—and of an unconsciousness which would be much wider than the personal one. However, for Salah Stétié, the poet, far from livig in Utopia, develops an “overhanging citizenship” who allows him to travel in all the areas of the reality, to embrace them and to testify of them without any exclusive.

In lieu of an abstract, here is a brief excerpt of the content:Reply to Russell's letter of 16 May 1960 by Albert Shalom EDITORIAL NOTE To illustrate a list ofrecent acquisitions in Russell (Summer 1981), we printed in facsimile Russell's letter of 16 May 1960 to Professor Albert Shalom concerning the interpretation of Wittgenstein's Tractatus LogicoPhilosophicus. The correspondence between Russell and Shalom began when Shalom wrote on I May 1960 asking whether Russell had the time and inclination to (...) read a translation of a lecture which Shalom had given the previous December in Paris. The paper was entitled "The Metaphysical Thinking Underlying Wittgenstein's Tractatus". Shalom had received "different and even contradictory appraisals" of his paper, and he very much wanted to have Russell's opinion of it. Close to the age ofninety, Russell was entering a hectic period in his life in which he worked assiduouslyfor the Campaign for Nuclear Disarmament. He had published three books in 1959 and had produced prefaces and introductions for other people. As usual, he was besieged with mail including numerous requests to read unsolicited manuscripts sent to him quite regularly. Yet he had managed to answer correspondence in a very personal way. In November 1959, he had been involved in a controversy regarding the refusal ofthe editor of Mind to review Ernest Gellner's Words and Things, a book which attacked the then prevalent philosophy of linguistic analysis and for which Russell had written the introduction. In the early months of1960, he took time out from his usual writing on the nuclear threat to reply to several articles devoted to his theory of descriptions and his ethical theory in the journal Philosophy. Russell's reply (4 May 1960) to Shalom's first letter states: "Thank you for your letter ofMay I. I shall be interested to see your paper on Wittgenstein's Tractatus, but, as I am very busy, it may be some time before I can read it carefully." On 8 May Shalom wrote back in appreciation enclosing his paper and an offprint of an article, "Qu'est-ce qu'un concept?", Revue internationale dephilosophie, 50 (1959): I-IS. The main objection raised against his paper, Shalom admitted, was that Wittgenstein was not concerned with problems of epistemology at the time of his writing the Tractatus. Nonetheless, Shalom felt that the "picture theory" of reality implies an epistemology, and he was unable to see a fallacy in his paper: "Perhaps the fact that I'm not a logician has something to do with the matter. Ifyou could enlighten me on this point I should be most grateful to you." 45 28th April 1982. 46 Russell winter 1982-83 Russell's letter of 16 May followed. On 25 May Shalom challenged Russell's interpretation. Far /rom underestimating the notion of structure, Shalom claimed that he had emphasized the notion as the key to understanding the Tractatus. "In fact, my main point is that Wittgenstein's analyses of various concepts are unintelligible unless understood as arguments in terms of the dominating idea ofstructure or form. And that is what I understand as a metaphysical argument." Shalom went on to say that his interest in any philosopher was to try to discover the chief concepts employed in the philosopher's analysis and to examine the manner in which the analysis was performed. For this reason, the later Wittgenstein was not devoid ofinterest. In a postscript, he asked Russell whether he would be in London in July ofthat year, and ifso, whether a meeting was possible. Russell replied on 18June as follows: "Thank you for your letter ofMay 25. I am sorry that at present my time and thought are so occupied with matters very remote from those with whichyour letter deals that I cannot offeryou a reasoned reply. Unfortunately, I do not expect to be in London in July so that I am afraid a meeting will hardly be possible." On 14 Shalom requested the return of his paper, and Russell complied on 19 July. Shalom is now Professor ofPhilosophy at McMaster. We invited him to comment on his exchange with Russell, particularly Russell's letter of16 May 1960. His comments take the form ofa further (and no doubtfinal) letter in the exchange.-Carl... (shrink)

In this comprehensive introduction, Spencer presents a new story of the origins and development of American Pragmatism, from its emergence through the interaction of European and Indigenous American cultures to its contemporary status as a diverse, vibrant, and contested global philosophy. This is an indispensable guide for undergraduate students.

Sartre importe à l'histoire vivante de la philosophie sous plusieurs angles. Héritier de Hegel qui le hante, il conteste celui-ci dans sa conviction « totaliste ». S'il reste fidèle au dynamisme hégélien, à l'interrogation constante du vécu, il les traduit pourtant par nos langages présents.

As a conceptual approach in art practice, the female body has represented both a cultural barrier and a source of inspiration throughout art history. The adoption of the female body as an art theme is prevalent across many different artistic movements, using varying conceptual approaches. Women struggle against paradigms of inferiority to this day, though their individual cultural identity varies according to their society’s beliefs and customs – for example, many contemporary Middle Eastern cultures and customs are based on a (...) patriarchal past, when men wielded power over women. Women all over the world experience subjugation to varying degrees in the fields of employment, education, sexuality and reproductive choice. The female body in Middle Eastern societies is a red line that artists are not allowed to cross. Though many Middle Eastern civilizations have dealt freely with the female body, as can be seen in the paintings and sculptures of ancient Egypt, many social and religious factors made the female body taboo in most Middle Eastern cultures. However, on close scrutiny of modern art history in Middle Eastern and Islamic countries, we can identify outstandingly courageous female artists who succeeded in breaking the rules. They chose to express themselves through their own own form of art as an expression of freedom. They chose to use their own bodies as an art medium, which made them pioneers in their countries, and many female artists followed their example. Media art has flourished in Arab countries since the 1990s, especially in Egypt. Many of these female artists distinguished themselves as pioneers, aligning themselves with new art forms and challenging the prevailing stereotypical notion of the female artist at that time. This new mode of female self-expression and identity has developed over time and remains an ongoing process in the twenty-first century. This article considers how Middle Eastern female media artists have struggled to transform stereotypes of women by using their own bodies as an artistic element, and how they have expressed the concept of freedom through their self-body image.
