“Dance” has been associated with many psychophysiological and medical health effects. However, varying definitions of what constitute “dance” have led to a rather heterogenous body of evidence about such potential effects, leaving the picture piecemeal at best. It remains unclear what exact parameters may be driving positive effects. We believe that this heterogeneity of evidence is partly due to a lack of a clear definition of dance for such empirical purposes. A differentiation is needed between (a) the effects on the (...) individual when the activity of “dancing” is enjoyedas a dancerwithindifferent dance domains(e.g.,professional/”high-art”type of dance,eroticdance,religiousdance,clubdancing,Dance Movement Therapy(DMT), and what is commonly known ashobby, recreationalorsocialdance), and (b) the effects on the individual within these different domains, as a dancer of thedifferent dance styles(solo dance, partnering dance, group dance; and all the different styles within these). Another separate category of dance engagement is, not as a dancer, but as a spectator of all of the above. “Watching dance” as part of an audience has its own set of psychophysiological and neurocognitive effects on the individual, and depends on the context where dance is witnessed. With the help of dance professionals, we first outline some different dance domains and dance styles, and outline aspects that differentiate them, and that may, therefore, cause differential empirical findings when compared regardless (e.g., amount of interpersonal contact, physical exertion, context, cognitive demand, type of movements, complexity of technique and ratio of choreography/improvisation). Then, we outline commonalities between all dance styles. We identify six basic components that are part of any dance practice, as part of a continuum, and review and discuss available research for each of them concerning the possible health and wellbeing effects of each of these components, and how they may relate to the psychophysiological and health effects that are reported for “dancing”: (1) rhythm and music, (2) sociality, (3) technique and fitness, (4) connection and connectedness (self-intimation), (5) flow and mindfulness, (6) aesthetic emotions and imagination. Future research efforts might take into account the important differences between types of dance activities, as well as the six components, for a more targeted assessment of how “dancing” affects the human body.

This thesis studies the formation of rules of experience in Weberian methodology and its adequacy to scientific validation criteria. It was sought to investigate, in the first part of the work, a proposal of justification for the so-called eligibility criteria. It was also tried to explain the meaning used in this research of the term “reason”, which is based on the theoretical conception of the operative reason exposed by Newton da Costa. Again, with the help of the writings of the (...) same author, we have examined those, so named by him, pragmatic principles of scientific reason. The second section of this study presented the three eligibility criteria, namely: i) the difference between to be (sein) and to ought to be (sollen); ii) the possibility of subsumption of individual action; iii) the construction of concepts as ideal types. In the third part of this work, rationally correct action was justified as an anticipated conjecture for a reflexive operation. However, it was supported that there is a significant difference in relation to the rules of experience when applied for the construction of the agent’s actions and in their use for validating the imputation of causal links between social phenomena. In order to validate the results of the research, the rules of experience must be cleverly designed to be general propositions of the experiment, and for this, the characterization of these rules was based in the so-called “Fermi solution”. Subsequent to this methodological proposal, we pondered how the scientist conducts a thought experiment in the empirical sciences of action and the judgment of objective possibility as a counterfactual proposition was logically structured. Thus, we tried to demonstrate the logical structure of the validation mode of knowledge produced in the empirical sciences of action from Weberian pattern. (shrink)

We summarize the essential ingredients, which enabled us to derive the path-integral for a system of harmonically interacting spin-polarized identical particles in a parabolic confining potential, including both the statistics (Bose–Einstein or Fermi–Dirac) and the harmonic interaction between the particles. This quadratic model, giving rise to repetitive Gaussian integrals, allows to derive an analytical expression for the generating function of the partition function. The calculation of this generating function circumvents the constraints on the summation over the cycles of the permutation (...) group. Moreover, it allows one to calculate the canonical partition function recursively for the system with harmonic two-body interactions. Also, static one-point and two-point correlation functions can be obtained using the same technique, which make the model a powerful trial system for further variational treatments of realistic interactions.

We discuss the case against Factorism, which is the standard assumption in quantum mechanics that the labels of the $$\otimes$$ ⊗ -factor Hilbert-spaces in direct-product Hilbert-spaces of composite physical systems of similar particles refer to particles, either directly or descriptively. We distinguish different versions of Factorism and argue for their truth or falsehood. In particular, by introducing the concepts of snapshot Hilbert-space and Schrödinger-movie, we demonstrate that there are Hilbert-spaces and $$\otimes$$ ⊗ -factorisations where the labels do refer, even descriptively, (...) to similar particles, which renders them probabilistically absolutely discernible.

Exploring the connection between Bentham and Byron forged by the Greek struggle for independence, this book focuses on the activities of the London Greek Committee, supposedly founded by disciples of Jeremy Bentham, which mounted the expedition on which Lord Byron ultimately met his death in Greece. Rosen's penetrating study provides a new assessment of British philhellenism and examines for the first time the relationship between Bentham's theory of constitutional government and the emerging liberalism of the 1820s. Breaking new ground in (...) the history of political ideas and culture in the early nineteenth century, Rosen advances striking new interpretations based on recently published texts and manuscript sources of the development of constitutional theory from Locke and Montesquieu, the conflicting strands of liberalism in the 1820s, and the response in Britain to strong claims for national self-determination in the Mediterranean basin. He sets out to distinguish between Bentham's theory and the ideological context against which it is usually interpreted. (shrink)

Following with the discovery of the electron by J. J. Thomson at the end of the nineteenth century a steady elucidation of the structure of the atom occurred over the next 40 years culminating in the discovery of nuclear fission in 1938–1939. The significant steps after the electron discovery were: discovery of the nuclear atom by Rutherford (Philos Mag 6th Ser 21:669–688, 1911 ), the transformation of elements by Rutherford (Philos Mag 37:578–587, 1919 ), discovery of artificial radioactivity by Joliot-Curie (...) and Joliot-Curie (Comptes Rendus Acad Sci Paris 198:254–256, 1934 ), and the discovery of the neutron by Chadwick (Nature 129:312, 1932a , Proc R Soc Ser A 136:692–708, 1932b ; Proc R Soc Lond Ser A 136:744–748, 1932c ). The neutron furnished scientists with a particle able to penetrate atomic nuclei without expenditure of large amounts of energy. From 1934 until 1938–1939 investigations of the reaction between a neutron and uranium were carried out by E. Fermi in Rome, O. Hahn, L. Meitner and F. Strassmann in Berlin and I. Curie and P. Savitch in Paris. Results were interpreted as the formation of transuranic elements. After sorting out complex radio-chemistry and radio-physics O. Hahn and F. Strassmann came to the conclusion, beyond their belief, that the uranium nucleus split into smaller fragments, that is nuclear fission. This was soon followed in 1939 by its theoretical interpretation by L. Mietner and O. Frisch. (shrink)

Quons are particles characterized by the parameter q, which permits smooth interpolation between Bose and Fermi statistics; q = 1 gives bosons, q = -1 gives fermions. In this paper we give a heuristic argument for an extension of conservation of statistics to quons with trilinear couplings of the form ffb, where f is fermion-like and b is boson-like. We show that q f 2 = qb. In particular, we relate the bound on qγ for photons to the bound on (...) qe for electrons, allowing the very precise bound for electrons to be carried over to photons. An extension of this argument suggests that all particles are fermions or bosons to a high precision. (shrink)

A central issue of cognitive neuroscience is to understand how a large collection of coupled neurons combines external signals with internal memories into new coherent patterns of meaning. An external stimulus localized at some input spreads over a large assembly of coupled neurons, building up a collective state univocally corresponding to the stimulus. Thus, the synchronization of spike trains of many individual neurons is the basis of a coherent perception. Based on recent investigations of homoclinic chaotic systems and their synchronization, (...) a novel conjecture for the dynamics of single neurons and, consequently, for neuron assemblies is formulated. Homoclinic chaos is proposed as a suitable way to code information in time by trains of equal spikes occurring at apparently erratic times. In order to classify the set of different perceptions, the percept space can be given a metric structure by introducing a distance measure between distinct percepts. The distance in percept space is conjugate to the duration of the perception in the sense that an uncertainty relation in percept space is associated with time-limited perceptions. This coding of different percepts by synchronized spike trains entails fundamental quantum features which are not restricted to microscopic phenomena. It is conjectured that they are related to the details of the perceptual chain rather than depending on Planck's action. (shrink)
