Taking regular walks when living with Parkinson’s disease has beneficial effects on movement and quality of life. Yet, patients usually show reduced physical activity compared to healthy older adults. Using auditory stimulation such as music can facilitate walking but patients vary significantly in their response. An individualized approach adapting musical tempo to patients’ gait cadence, and capitalizing on these individual differences, is likely to provide a rewarding experience, increasing motivation for walk-in PD. We aim to evaluate the observance, safety, tolerance, (...) usability, and enjoyment of a new smartphone application. It was coupled with wearable sensors and delivered individualized musical stimulation for gait auto-rehabilitation at home. Forty-five patients with PD underwent a 1-month, outdoor, uncontrolled gait rehabilitation program, using the BeatWalk application. The music tempo was being aligned in real-time to patients’ gait cadence in a way that could foster an increase up to +10% of their spontaneous cadence. Open-label evaluation was based on BeatWalk use measures, questionnaires, and a six-minute walk test. Patients used the application 78.8% of the prescribed duration and enjoyed it throughout the program. The application was considered “easy to use” by 75% of the patients. Pain, fatigue, and falls did not increase. Fear of falling decreased and quality of life improved. After the program, patients improved their gait parameters in the six-minute walk test without musical stimulation. BeatWalk is an easy to use, safe, and enjoyable musical application for individualized gait rehabilitation in PD. It increases “walk for exercise” duration thanks to high observance.Clinical Trial Registration: ClinicalTrials.gov Identifier: NCT02647242. (shrink)

In human groups performing oscillatory tasks, it has been observed that the frequency of participants' oscillations reduces when compared to that acquired in solo. This experimental observation is not captured by the standard Kuramoto oscillators, often employed to model human synchronization. In this work, we aim at capturing this observed phenomenon by proposing three alternative modifications of the standard Kuramoto model that are based on three different biologically-relevant hypotheses underlying group synchronization. The three models are tuned, validated and compared against (...) experiments on a group synchronization task, which is a multi-agent extension of the so-called mirror game. (shrink)

Le cours de Bergson dont il est ici question, donné au Lycée Blaise Pascal durant l'année scolaire 1885-1886, sera envisagé sous l'angle de la responsabilité que tout philosophe contracte en pratiquant la philosophie, transmettre aux "nouveaux", comme disait Platon, cet usage de la raison qui est le meilleur garant de la vérité, de la justice et de la liberté. On y voir Bergson instruire ceux qui lui sont confiés, transmettre les connaissances qu'il a reçues, former leur jugement, aiguiser leur sens (...) critique par un discours exigeant, rigoureux, susciter le souci de la vérité, le goût des sciences et leur enseigner les chemins qu'à suivis cette extraordinaire aventure de la pensée commencée en Grèce il y a 2500 ans.

Johannes Müller von Königsberg (1436-1476), better known as Regiomontanus, is widely considered as the most influential astronomer and mathematician of 15th-century Europe. He was active as an astrologer and deemed astrology to be the queen of mathematical sciences. Despite this, Regiomontanus's astrological activity has yet to be fully explored. A brief examination of Regiomontanus's manuscripts shows that his astrological interests were accompanied by interests in the arts and in methods of prognostication. This article studies an unconventional astrological-chiromantical text, whose relevance (...) is threefold: a) it sheds new light on Regiomontanus's astrological interests; b) it enriches our knowledge of Regiomontanus's efforts to learn and understand Greek-Regiomontanus transcribed it into his own manuscript during his sojourn in Italy from 1460-1467; and c) it is the sole extant text in the Greek tradition that provides a system for prognostication from the study of a person's hand, the parts of which are considered as being under the domain of planets. The article provides an English translation of Regiomontanus's transcription, alongside a brief commentary, and studies the intellectual and historical context of that production through manuscript analysis.

In this target article we question the assumption that perception is divided into separate domains of vision, hearing, touch, taste, and smell. We review implications of this assumption for theories of perception and for our understanding of ambient energy arrays (e.g., the optic and acoustic arrays) that are available to perceptual systems. We analyze three hypotheses about relations between ambient arrays and physical reality: (1) that there is an ambiguous relation between ambient energy arrays and physical reality, (2) that there (...) is a unique relation between individual energy arrays and physical reality, and (3) that there is a redundant but unambiguous relation, within or across arrays, between energy arrays and physical reality. This is followed by a review of the physics of motion, focusing on the existence and status of referents for physical motion. Our review indicates that it is not possible, in principle, for there to be a unique relation between physical motion and the structure of individual energy arrays. We argue that physical motion relative to different referents is specified only in the global array, which consists of higher-order relations across different forms of energy. The existence of specificity in the global array is consistent with the idea of direct perception, and so poses a challenge to traditional, inference-based theories of perception and cognition. However, it also presents a challenge to much of the ecological approach to perception and action, which has accepted the assumption of separate senses. (shrink)

Nel Marc. gr. Z. 333, testimone del testo astronomico intitolato Παράδοσις εἰς τοὺς περσικοὺς κανόνας τῆς ἀστρονομίας, copiato da Bessarione, sono presenti delle aggiunte, dovute all’intervento di Bessarione stesso, che si ritrovano nella tradizione manoscritta dell’opera soltanto nei discendenti del Marc. gr. Z. 333. Tali aggiunte sono tratte da un testo astronomico di Isacco Argiro e da una versione della Paradosis riveduta da Teodoro Meliteniote. L’analisi filologica e paleografica dimostra che in entrambi i casi le aggiunte sono ricavate da un (...) codice di Giovanni Cortasmeno. Ciò dimostra che il Bessarione ebbe Cortasmeno come maestro non solo nella filosofia aristotelica, ma anche nell’astronomia, e che dunque il suo interesse per questa scienza si sviluppò già nella fase poco nota della sua formazione giovanile a Costantinopoli, e non solo, come si riteneva sino ad oggi, sotto la guida di Giorgio Gemisto Pletone a Mistrà dopo il 1431.

The article attempts to trace the origins and to assess the extent ofparty-system change in Italy in the 1990s. It also examines some hypotheses on the possible causes of such changes. Building on research on anti-party sentiment and on changes in party organization the paper begins with an analysis of the evolution of the party system in the last 30 years which identifies organizational adaptation as a delaying factor in party system change. This is followed by a description of the (...) party system after the 1994 elections based on generally accepted party system characteristics and indicators. The assessment is made difficult by the, perhaps temporary, coexistence of two party-systems, respectively relevant for electoral and inter-election competition. The evidence however, suggests, that party-system transformation is under way, while it might still be inappropriate to talk about structural change. Degeneration of parties and a deep institutional crisis appear to be the factors leading to the explosion of pent-up alienation and antiparty sentiments, and to demands for institutional and constitutional change that preceded and appeared to be the immediate causes of party system transformation.

This paper is a preliminary study focused on the astronomical manuscript Marcianus latinus VIII.31 (2614) and its socio-historical context of use and production, the Venetian colony of Crete in the 15th century. It is a relevant source for the study of scientific interactions in colonial, multilinguistic, and interreligious contexts in the Eastern Mediterranean for at least two reasons: (a) it contains an unpublished translation into Latin of a popular Byzantine handbook on how to use a set of astronomical tables stemming (...) from Islamic sources, namely the so-called Paradosis of the Persian Tables, a work extensively copied and annotated by very significant Byzantine and Jewish scholars active in Constantinople; and (b) it provides evidence of a Byzantine product being the object of exchange in the interactions between Christians and Jews in the Cretan territory under Venetian rule.

Bodily expression of felt emotion has been documented in the literature. However, it is often associated with high motor variability between individuals. This study aimed to identify individual motor signature of emotions. IMS is a new method of motion analysis and visualization able to capture the subtle differences in the way each of us moves, seen as a kinematic fingerprint. We hypothesized that the individual motor signature would be different depending on the induced emotional state and that an emotional motor (...) signature of joy and sadness common to all participants would emerge. For that purpose, we elicited these emotions in 26 individuals using an autobiographical memory paradigm, before they performed a motor improvization task. We extracted the individual motor signature under each emotional condition. Participants completed a self-report emotion before and after each trial. Comparing the similarity indexes of intra- and inter-emotional condition signatures, we confirmed our hypothesis and showed the existence of a specific motor signature for joy and sadness, allowing us to introduce the notion of emotional individual motor signature. Our study indicates that EIMS can reinforce emotion discrimination and constitutes the first step in modeling emotional behavior during individual task performances or social interactions. (shrink)

Do foreign direct investment (FDI) and international business ventures promote positive social and economic development in emerging nations? This question will always prove contentious. First, the impacts differ according to context. Second, the social consequences and spillover effects of knowledge diffusion and technology-sharing may be limited and hard to measure. Third, contributions to enhancing social responsibility and improving living standards in host countries are delayed in effect, causally complex, and also hard to measure. Outcomes often critically depend on collaboration of (...) governments, international institutions, the business world, and non-governmental organizations (NGOs). Research in this area is challenging and requires interdisciplinary collaboration between economists, financial experts, sociologists, ethicists, and other specialists. This paper explores: (1) the evidence to support the proposition that FDI and international business improve social conditions in less-developed countries, and: (2) how these improvements are linked to strategies of corporate social responsibility (CSR) and ethical business practice. The paper draws insights from development, FDI, poverty alleviation, and bottom-of-the-pyramid (BOP) literature. Applications are demonstrated using examples from poverty-stricken areas of Sub-Saharan Africa. The paper attempts not only to argue theoretically but also to provide practical evidence. The approach is simultaneously descriptive, analytical, and prescriptive in order to address a wide audience. It also highlights issues and trends for further academic research and presents the viewpoint that some limitations lie in the nature of ethics frameworks widely referenced in business and that these often fail to consider the compatibility of ethical constructs with relevant incentives. In this vein, we explore the application of Homann’s framework for advantage and incentive-based ethics. (shrink)

The new commentaries raise important issues about the target article (Stoffregen & Bardy 2001). The commentaries also highlight some assumptions, often implicit, that underlie traditional interpretations of perception. We argue that evaluation of the global array and its implications for perception requires both analytical research on specification in the global array and new empirical research on the use of information in the global array for the control of action.

We discuss issues raised by the commentators, such as specification in single-energy arrays, task-specific pickup of information, general principles of the ecological approach to perception and action, and how specification may be constrained by the facts of physical relativity. While the commentaries raise many important issues we conclude that they do not undermine our argument that specification exists solely in the global array.

Written in broad strokes, this paper attempts to draw form Krishnamurti’s life and teachings, a hermeneutics of the human soul’s quest-journey towards transcendent wholeness. It begins with an attempt to frame K’s “process” (the name given to the painful ordeals in his youth that many believe were the catalyst responsible for his metamorphosis) through a variety of disciplines and cultural perspectives, some of which underscore the impasse of scientific objectivity and the limits of phenomenalist categories in general. It then explores (...) the procedures and conceits of present technologies of self-transformation via pseudomeditative body work and suggests that this subject can only be confirmed by an experience so intimately and subversively (to its own object) subjective that it risks undermining its own legitimacy in the face of our body-phobic Cartesian cultural ethos that holds sacrosanct the mind-body split. -/- It then explores the deeper origins and history of this problem from the pre-Socratics to the misconceptions of modern mathematics about the proper place of metaphor and paradox and underscores how present day false consciousness fails to discriminate between a “noumenal” world and its conditioned “phenomenal” counterfeit copy. It ends with a brief meditation on K’s process. (shrink)

The paper contrasts the economic, ethical, and organizational differences in the U.S. and Europe, as well as the differences in governance and leadership between U.S. and European managers, and how these differences impact decision-making and governance of U.S. and European businesses. In addition, the paper explores and contrasts select ethical and cultural issues between managers on both sides of the Atlantic. It is the authors' view that on both sides of the Atlantic we embrace the call for more ethics in (...) our lives and we expect it from our business leaders and our business dealings. However, in the markets we consistently have seen a short-term orientation of corporate outcomes. It is hoped that there will be a silver lining to the current economic crisis that will help move us away from this position which makes things like ethics, long-term virtues, fairness, all nice to talk about but somewhat estranged from the realities that are practiced in businesses. It remains to be seen if U.S. organizations, business schools and business leaders will change this current position more rapidly than in Europe. The authors are confident, however, that businesses and governments on both sides of the Atlantic will make all efforts for a pronounced transition to integrate ethics into the real strategic thrusts of conducting business.

Leadership, corporate responsibility and management ethics underline the human centered paradigm in the complex world of today. One major issue in management is impact on people. This book relates to the outcomes of human interaction within and beyond the borders of an organization. It discusses what motivates moral behavior at the individual and the collective levels, how morality is engrained in markets and how it is deployed in business processes and stakeholder relations. The book shows that human centered management is (...) built and consolidated in four complementary dimensions: ethical, social, economic and institutional. It emphasizes that moral managers and moral markets are essential for business sustainability. Rethinking Leadershipcovers ethics development from its origin to help managers understand and confront the 21st century's increasing challenges and disruptions. Its clear narrative and cogent examples bridge scholars and practitioners, with distinctive examples on how to implement human centered management and how to teach the subject to executives. The author has 30 years of business experience in developed and developing countries and 20 years in academia in the US and in Europe, which provides solid background to effectively and affectively discuss the topic from the multiple angles.

Emotions are a natural vector for acting together with others and are witnessed in human behaviour, perception and body functions. For this reason, studies of human-to-human interaction, such as multi-person motor synchronisation, are a perfect setting to disentangle the linkage of emotion with socio-motor interaction. And yet, the majority of joint action studies aiming at understanding the impact of emotions on multi-person performance resort to enacted emotions, the ones that are emulated based on the previous experience of such emotions, and (...) almost exclusively focus on dyadic interaction. In addition, tasks chosen to study emotion in joint action are frequently characterised by a reduced number of physical dimensions to gain experimental control and subsequent facilitation in data analysis. Therefore, it is not clear how naturalistically induced emotions diffuse in more ecological interactions with other people and how emotions affect the process of interpersonal synchronisation. Here, we show that positive and negative emotions differently alter spontaneous human synchronous behaviour during a multi-person improvisation task. The study involved 39 participants organised in triads who self-reported liking improvisational activities. The task involved producing improvisational movements with the right hand. Participants were emotionally induced by manipulated social feedback involving a personal ranking score. Three-dimensional spatio-temporal data and cardiac activity were extracted and transformed into oscillatory signals to compute behavioural and physiological synchrony. Our results demonstrate that individuals induced with positive emotions, as opposed to negative emotions or a neutral state, maintained behavioural synchrony with other group members for a longer period of time. These findings contribute to the emerging shift of neuroscience of emotion and affective sciences towards the environment of social significance where emotions appear the most—in interaction with others. Our study showcases a method of quantification of synchrony in an improvisational and interactive task based on a well-established Kuramoto model. (shrink)

The paper provides a reconstruction of the notion of material Apriori while exhibiting the anti-Kantian inspiration and factual grounding thereof. The attempt is made to show that a non-formal Apriori obtains because the sensuous has a normative character; further, that the difference between material and formal eidetic laws is rooted in the difference between sensuous contents, given in experience, and intellectual contents, originating in activities of judgement. The material Apriori is not independent of all experience, since it is grounded on (...) sensuous eidetic contents and thus depends on the latter’s givenness and characteristics. It is thanks precisely to this ,contingency‘ that it has an ontological significance. (shrink)

Hegel is most famous for his view that conflicts between contrary positions are necessarily resolved. Whereas this optimism, inherent in modernity as such, has been challenged from Kierkegaard onward, many critics have misconstrued Hegel's own intentions. Focusing on the Science of Logic, this transformative reading of Hegel on the one hand exposes the immense force of Hegel's conception of tragedy, logic, nature, history, time, language, spirit, politics, and philosophy itself. Drawing out the implications of Hegel's insight into tragic conflicts, on (...) the other hand, De Boer brings into play a form of negativity that allows us to understand why the entanglement of complementary positions always tends to turn into their conflict, but not necessarily into its resolution.

Un verbe exprime en français l'un des secrets de notre être et l'une des clés de notre époque maniaco-dépressive : ce verbe, c'est revivre. Il a deux sens que tout paraît opposer. Revivre, c'est en effet renaître, retrouver le sentiment d'être vivant et relié à autrui. Mais c'est aussi se laisser rattraper par "un passé qui ne passe pas » et se replier sur soi-même. Chacun de nous fait cette double expérience, souvent sans le savoir. Il faut pourtant la penser, (...) l'affronter, résister à ce qui nous enferme, accéder à ce qui nous délivre. Inventaire de nos blessures et de nos ressources, diagnostic du moment présent, parcours dans les idées et les oeuvres, ces propos renouent avec les actes les plus intenses de notre vie. Un art de vivre, c'est-à-dire de revivre, qui pourrait bien être le seul possible aujourd'hui. (4e de couv.). (shrink)

From classic aesthetic theories to fresh aesthetic methods, this volume is an accessible introduction to the main topics in contemporary aesthetics: the media-technological challenges, transcultural aesthetics and aesthetic methodology.

De Muralt's ambition is to carry out such 'historical' inquiries in the form of a structural analysis of philosophy, which he regards as a rigorous philosophical discipline - that is, as a science.
