This study investigated the differences in morphometry and functional plasticity characteristics of the brain after long-term training of different intensities. Results showed that an aerobic group demonstrated higher gray matter volume in the cerebellum and temporal lobe, while an anaerobic group demonstrated higher gray matter volume in the region of basal ganglia. In addition, the aerobic group also showed significantly higher fractional amplitude of low-frequency fluctuation and degree centrality in the motor area of the frontal lobe and parietal lobe, and (...) the frontal gyrus, respectively. At the same time, the anaerobic group demonstrated higher fALFF and DC in the cerebellum posterior lobe. These findings may further prove that different brain activation modes respond to different intensities of physical activity and may help to reveal the neural mechanisms that can classify athletes from different intensity sports.

Various walking speeds may induce different responses on the plantar pressure patterns. Current methods used to analyze plantar pressure patterns are linear and ignore nonlinear features. The purpose of this study was to analyze the complexity of plantar pressure images after walking at various speeds using nonlinear bidimensional multiscale entropy. Twelve participants were recruited for walking at three speeds for 20 minutes. A plantar pressure measurement system was used to measure plantar pressure patterns. Complexity index, a summation of MSE2D from (...) all time scales, was used to quantify the changes of complexity of plantar pressure images. The analysis of variance with repeated measures and Fisher’s least significant difference correction were used to examine the results of this study. The results showed that CI of plantar pressure images of 1.8 mph was significantly lower compared with 3.6 and 5.4 mph. The results also showed that CI significantly increased from the 1st min to the 10th min and 20th min with slow walking. Our results indicate that slow walking at 1.8 mph may not be good for postural control compared with moderate walking and fast walking. This study demonstrates that bidimensional multiscale entropy is able to quantify complexity changes of plantar pressure images after different walking speeds. (shrink)

Since the Niels Bohr centenary of 1985 there has been an astonishing international surge of scholarly analyses of Bohr's philosophy. Now for the first time in Niels Bohr and Contemporary Philosophy Jan Faye and Henry Folse have brought together sixteen of today's leading authors who have helped mould this new round of discussions on Bohr's philosophy. In fifteen entirely new, previously unpublished essays we discover a surprising variety of the different facets of Bohr as the natural philosopher whose `framework of (...) complementarity' shaped the final phase of the quantum revolution and influenced two generations of the century's leading physicists. There is much on which the authors included here agree; but there are also polar disagreements, which assure us that the philosophical questions revolving around Bohr's `new viewpoint' will continue to be a subject of scholarly interest and discussion for years to come. This collection will interest all serious students of history and philosophy of science, and foundations of physics. (shrink)

The paper discusses the impact of the thought of Stanisław Brzozowski (1878–1911) on several Polish emigré writers, including Józef Czapski and Gustaw Herling-Grudziński, but first of all Czesław Miłosz (1911–2004) and Aleksander Wat (1900–1967). Miłosz’ approach oscillated between early fascination through an unjust rejection during the war, due to the “appropriation” of Brzozowski’s thought by the right wing publicists, to the new phase of fascination after the war, culminating in the publication of a book on Brzozowski ( A Man Among (...) Scorpions , 1962) and prolonged in several important articles till the very end of his life. Wat’s approach shifted from the communist practice of “overcoming” Brzozowski through the affirmation of his criticism and rejection of catholic obscurantism to the process of the internalization of the catholic faith.

We introduce a cyclic proof system for the two-way alternation-free modal μ-calculus. The system manipulates one-sided Gentzen sequents and locally deals with the backwards modalities by allowing analytic applications of the cut rule. The global effect of backwards modalities on traces is handled by making the semantics relative to a specific strategy of the opponent in the evaluation game. This allows us to augment sequents by so-called trace atoms, describing traces that the proponent can construct against the opponent’s strategy. The (...) idea for trace atoms comes from Vardi’s reduction of alternating two-way automata to deterministic one-way automata. Using the multi-focus annotations introduced earlier by Marti and Venema, we turn this trace-based system into a path-based system. We prove that our system is sound for all sequents and complete for sequents not containing trace atoms. (shrink)

Background: The application of the philosophical mode of investigation called “phenomenology” in the context of sport. Objective: The goal is to show how and why the phenomenological method is very often misused in the sportrelated research. Methods: Interpretation of the key texts, explanation of their meaning. Results: The confrontation of concrete sport-related texts with the original meaning of the key phenomenological notions shows mainly three types of misuse – the confusion of phenomenology with immediacy, with an epistemologically subjectivist stance (phenomenalism), (...) and with empirical research oriented towards objects in the world. Conclusions: Many of the discussed authors try to take over the epistemological validity of phenomenology for their research, which itself is not phenomenological, and it seems that this is because they lack such a methodological foundation. The authors believe that an authentically phenomenological analysis of sport is possible, but it must respect the fundamental distinctions that differentiate phenomenology from other styles of thinking.

This book interprets and reflects on the conception of God that is implied by the Lord’s Prayer. It explains the epistemic status and ontological implications of the Christian faith in God and proposes a non-essentialist account of central identity-defining attributes of God.

I argue that meaning is a result of our biological evolution, and that language evolved from primates’ ability to grasp conceptually the most important features of their environment. I hold that natural selection and adaptation ensure that primates both sense and conceptualize their world similarly, and that they therefore think similarly, whenever they receive the same sense impressions. This cognitive similarity enabled our predecessors to learn and develop a language because of the regular association of a particular sound and a (...) particular image. The evolutionary pressure on our predecessors to develop a language was the advantage that such a language had for cooperation and survival. Finally, I argue that the old, but in wider circles frowned-upon theory of meaning, the expressive theory of language, provides the best explanation of the relationship between thought, meaning, and words, because it operates with words and not sentences as the basic semantic unit.

I convenzionalisti sostengono che le verità fondamentali relative a un qualche ambito (come quelle dell’etica o della matematica) siano non il riflesso dell’esistenza di certi fatti relativi a quell’ambito, “che sono lì a prescindere”, bensì che siano fondate meramente in accordi espliciti o impliciti tra parlanti che parlano di quegli argomenti. Esse non sono verità relative al mondo intorno a noi, bensì verità generate da un sistema di convenzioni che noi stessi abbiamo stabilito. Di conseg...

Most metaphysicians deny that dispositions are among the fundamental constituents of the world. The solubility of salt, for example, is regarded as derivative from more basic features of reality, such as the molecular structure of salt and the laws of nature. This is an initially plausible view: a disposition seems to be essentially a characterization of what its bearer can do, which seems to be wholly dependent on what that bearer is like. ;Nonetheless, I think that the most attractive view (...) of dispositions is that they are fundamental constituents of reality---in fact, almost all real properties are irreducibly dispositional. Following D. M. Armstrong, I call this view dispositionalism. In my dissertation, I address several major difficulties for dispositionalism. For instance, it is often argued that dispositionalism makes causal relations necessary, and is thus committed to an unacceptable theory of causation. In response to this worry, I defend the thesis that causal relations are necessary. A second objection is based on C. B. Martin's "finkish" cases. It is widely accepted that some accounts of dispositions are able to escape this objection by adopting David Lewis's response to it. Contra Lewis, I argue that dispositionalism can follow in their footsteps. Finally, I consider the objection that dispositionalism, by implying that it is dispositions all the way down, leads to a vicious regress. I think that this is the most serious problem for dispositionalism, and although I do not fully lay it to rest, I make some headway. ;I also survey a wide range of competing theories of dispositions. I argue that the difficulties they face are both far greater than has been recognized, and more serious than the difficulties that beset dispositionalism. The result is not a conclusive proof of dispositionalism, but a demonstration that this underdog theory is preferable to its more popular competitors. (shrink)

The media coverage of immigration serves as an important test for modern democracies’ ability to handle difficult public issues. Systematic and comparative studies over longer time periods are, however, still rare. This is deeply unfortunate as the nature of both immigration and the press systems vary considerably not only across nations but also over time. This article charts the immigration debate in seven Scandinavian newspapers from the birth of modern immigration in the early seventies to the present-day situation. While supporting (...) claims about a general historical shift towards a more problematizing and cultural discourse in Scandinavia, the analysis also identifies major differences in how countries, publications, and genres have handled this complex issue, which brings out fundamental dilemmas for both modern welfare states and journalists. Using the method of multiple correspondence analysis and subsequent cluster analysis, the article also demonstrates how historical press coverage can be fruitfully studied using Geometric Data Analysis as an alternative to frequentist methods.

Light sheet microscopy is an easy to implement and extremely powerful alternative to established fluorescence imaging techniques such as laser scanning confocal, multi‐photon and spinning disk microscopy. By illuminating the sample only with a thin slice of light, photo‐bleaching is reduced to a minimum, making light sheet microscopy ideal for non‐destructive imaging of fragile samples over extended periods of time. Millimeter‐sized samples can be imaged rapidly with high resolution and high depth penetration. A large variety of instruments have been developed (...) and optimized for a number of different samples: Bessel beams form thin light sheets for single cells, and selective plane illumination microscopy (SPIM) offers multi‐view acquisition to image entire embryos with isotropic resolution. This review explains how light sheet microscopy involves a conceptually new microscope design and how it changes modern imaging in biology. (shrink)

The Right of Nonuse provides a fresh and remarkably different perspective on the real causes of the ills plaguing the world's resources and environment. It re-examines the very nature of nature, and from this new perspective, argues that what is needed is for humans to grant to natural resources a legal right to be left alone - a right of nonuse. In the process, it explores the following questions: Why do natural resources continue to be depleted and removed at an (...) alarming rate? Why are species becoming extinct at a pace that may be unprecedented? Why does the environment continue to be polluted? Why do the weather and climate seem to be changing? Perhaps most important, why have laws, legal institutions and governments been unable to address and correct these problems? Jan Laitos reviews the history of our relationship with the natural environment and develops new ways of thinking about nature and its protection. Instead of proceeding with human-based goals, Laitos argues that we should protect environmental resources for their own intrinsic value. Instead of giving humans more and more rights to clean up the environment, and to halt resources depletion, a right of nonuse held by the resource itself should be created. Natural resources have always possessed this parallel nonuse function, and society should recognize and legitimize it. (shrink)

Pacuvius is generally regarded as the first Roman playwright who only wrote tragedies; fragments transmitted without an indication of title or context are commonly attributed to tragedies, and ancient references to comedies are discarded as unreliable. The present paper questions this consensus. It first raises several methodological objections (section 1) and then examines two quotations preserved by Fulgentius, demonstrating that these comic fragments are unlikely to be forgeries because they comply with the rules of early Latin metre and the motivic (...) and linguistic conventions of Roman comedy (section 2). Section 3 shows that several fragments which have previously been attributed to tragedies do not fit the contexts to which they have been assigned; they have much closer parallels in New Comedy and are likely to come from comoediae palliatae. The observations in sections 1-3 corroborate each other and have three wider consequences which are discussed in section 4: first, Pacuvius was probably more faithful to his Greek models than is currently thought; secondly, the ‘specialization’ in serious drama started one generation later with Accius and Titius; thirdly, the common practice of organizing the fragments of early Roman poetry according to genre is problematic because many fragments would suit both a tragic and a comic context.
