Mindfulness-based training programs are highly established in competitive and recreational sports. One of the best-known approaches is the Mindfulness-Acceptance-Commitment Approach by Gardner and Moore), which integrates mindfulness aspects of awareness, non-judgmental attitude, and focus. Based on these aspects, Thienot and colleagues developed and validated an English language sport-specific questionnaire, the so-called Mindfulness Inventory for Sport, for the assessment of mindfulness skills in athletes. The aim of this study is to psychometrically test a German language version of the MIS. To assess (...) the psychometric properties, the MIS-D was examined in an online survey with an integrated test–retest design for reliability, validity, and measurement invariance. The present results support the psychometric quality of the German language version of the MIS. Necessary replications should among others focus on checking the measurement invariance for further relevant subgroups. (shrink)

Auch als originar politischer Denker ist Karl Jaspers reich an Einsichten: Ausgehend vom Ethos der Freiheit jedes Einzelnen richtet er seinen Blick auf die konkrete politische Gestaltung einer Freiheitsordnung. Dabei steht fur ihn im Hinblick auf die noch junge Bundesrepublik die Selbsterziehung in Freiheit im Zentrum seiner oft mahnenden Worte. Ganz im sokratischen Sinne fordert er intellektuelle Redlichkeit und politische Wahrhaftigkeit ein, um den beiden grossen Gegenwartsherausforderungen gewachsen zu sein: einer atomwaffenbestuckten Welt, die sich jederzeit selbst ausloschen kann, und (...) dem modernen Totalitarismus, der in seiner Verherrlichung des Antipolitischen allen politischen Ordnungsbestrebungen die Vernichtung androht. Jeder Frieden, der mehr ist als die Friedhofsruhe eines Waffenstillstands, grundet fur Jaspers in der politischen Freiheit handelnder Burgerinnen und Burger, die gemeinsam Sorge fur die Integritat ihres politischen Gemeinwesens tragen.

A teoria da implicatura constitui o principal legado de Paul Grice aos modernos estudos da pragmática linguística. Embora associado à filosofia da linguagem ordinária, seu pensamento não se apresenta marcado pela aversão à sistematização teórica que, segundo se diz, caracterizou essa corrente filosófica. Pelo contrário, a obra do filósofo inglês, apesar de dispersa em artigos só postumamente reunidos em livro, constitui um esforço coerente e rigoroso de analisar os princípios que explicam o comportamento racional do homem. Este ensaio oferece uma (...) tentativa de interpretação da análise que ele propôs para o fenômeno da implicatura, buscando integrar tal análise, progressivamente, ao quadro mais geral de sua filosofia da linguagem e de sua psicologia filosófica. De passagem, é sugerida uma aproximação, quanto aos propósitos, entre o programa filosófico de Grice e certa ensaística crítica do poeta argentino Jorge Luis Borges, sugestão talvez surpreendente, mas que pode se mostrar instrutiva.

We study a notion ofpartial primitive recursion (p.p.r.) including the concept ofparallelism in the context of partial continuous functions of type level one in the sense of [Krei], [Sco82], [Ers]. A variety of subrecursive hierarchies with respect top.p.r. is introduced and it turns out that they all coincide.

In Homer’s account of the adventurous journey of Odysseus, the song of the sirens was so appealing and tempting that it lured sailors to their deaths. Warned by the goddess Kirke, Odysseus overcame the trap by plugging his crew’s ears with wax. An archaeo-acoustical research expedition undertaken by members of Humboldt University Berlin made sound propagation experiments at the supposedly historical scene at the Galli Islands where it’s said that the sirens originally sung. At the site we broadcasted both synthetic (...) signals and natural voices via loudspeakers in the direction Odysseus most probably should have approached the Siren’s island. Subjective listening as well as objective acoustic analysis of the recorded signals revealed evidence for a combination of site-specific acoustic effects, which may explain the nature and origin of the song of the sirens in Homer. The local arrangement of the three islands deforms the acoustic signals by amplification and by changes in timbre. Two female singers from the Berlin State Opera were asked to sing differently pitched musical intervals to be tested in the Li Galli environment. The experiment evinced that the first overtones would be merged by the echo of the rocks; yet when singing pure thirds and less consonant intervals, which yield higher orders in the overtone series, the voices appear recognisable as being two. As a result, and particularly because Homer stresses the number of exactly two sirens several times, the evidence of our research supports the musicological theory for a rather early existence of enharmonic tunings and most prominently a two-part polyphonic singing of Greek songs. Given that the rocky formation of the Galli Islands most likely didn’t change during the geological tick of just 2,700 years, we conclude that there has been a real acoustic basis for the myth reported by Homer and that a “song of the Sirens”, most probably based on natural voices, was transformed by the particular acoustic conditions of the landscape in such a way that signals were amplified and sent out in one concrete direction. Based on these results, we continue to discuss further leading acoustic theories that offer new insights into the mythology and which were essential to motivate our expedition in the first place. After all, the question remains open what kind of beings the first emitters of the song might have been. (shrink)

The paper builds on both a simply typed term system ${\cal PR}^\omega$ and a computation model on Scott domains via so-called parallel typed while programs (PTWP). The former provides a notion of partial primitive recursive functional on Scott domains $D_\rho$ supporting a suitable concept of parallelism. Computability on Scott domains seems to entail that Kleene's schema of higher type simultaneous course-of-values recursion (scvr) is not reducible to partial primitive recursion. So extensions ${\cal PR}^{\omega e}$ and PTWP $^e$ are studied that (...) are closed under scvr. The twist are certain type 1 Gödel recursors ${\cal R}_k$ for simultaneous partial primitive recursion. Formally, ${\cal R}_k\vec{g}\vec{H}xi$ denotes a function $f_i \in D_{\iota\to\iota}$ , however, ${\cal R}_k$ is modelled such that $f_i$ is finite, or in other words, a partial sequence. As for PTWP $^e$ , the concept of type $\iota\to\iota$ writable variables is introduced, providing the possibility of creating and manipulating partial sequences. It is shown that the PTWP $^e$ -computable functionals coincide with those definable in ${\cal PR}^{\omega e}$ plus a constant for sequential minimisation. In particular, the functionals definable in ${\cal PR}^{\omega e}$ denoted ${\cal R}^{\omega e}$ can be characterised by a subclass of PTWP $^e$ -computable functionals denoted ${\rm PPR}^{\omega e}$ . Moreover, hierarchies of strictly increasing classes ${\cal R}^{\omega e}_n$ in the style of Heinermann and complexity classes ${\rm PPR}^{\omega e}_n$ are introduced such that $\forall n\ge 0. {\cal R}^{\omega e}_n ={\rm PPR}^{\omega e}_n$ . These results extend those for ${\cal PR}^\omega$ and PTWP [Nig94]. Finally, scvr is employed to define for each type $\sigma$ the enumeration functional $E^\sigma$ of all finite elements of $D_\sigma$. (shrink)

The paper studies a domain theoretical notion of primitive recursion over partial sequences in the context of Scott domains. Based on a non-monotone coding of partial sequences, this notion supports a rich concept of parallelism in the sense of Plotkin. The complexity of these functions is analysed by a hierarchy of classes ${\cal E}^{\bot}_n$ similar to the Grzegorczyk classes. The functions considered are characterised by a function algebra ${\cal R}^{\bot}$ generated by continuity preserving operations starting from computable initial functions. Its (...) layers ${\cal R}^{\bot}_n$ are related to those above by showing $\forall n \ge 2.{\cal E}^{\bot}_{n+1} ={\cal R}^{\bot}_n$ , thus generalising results of Schwichtenberg/Müller and Niggl.

A key problem in implicit complexity is to analyse the impact on program run times of nesting control structures, such as recursion in all finite types in functional languages or for-do statements in imperative languages.Three types of programs are studied. One type of program can only use ground type recursion. Another is concerned with imperative programs: ordinary loop programs and stack programs. Programs of the third type can use higher type recursion on notation as in functional programming languages.The present approach (...) to analysing run time yields various characterisations of fptime and all Grzegorczyk classes at and above the flinspace level. Central to this approach is the distinction between “top recursion” and “side recursion”. Top recursions are the only form of recursion which can cause an increase in complexity. Counting the depth of nested top recursions leads to several versions of “the μ-measure”. In this way, various recent solutions of key problems in implicit complexity are integrated into a uniform approach. (shrink)

How do Chinese and Western philosophical traditions interact today? In the underlying collection of articles both Chinese and Western scholars carefully examine the issue, one of fundamental importance for the mutual understanding of China and the West. The volume is the result of a symposium which sought to initiate a dialogue between China and the West on questions ranging from philosophy to politics and aesthetics. -/- The papers deal with various topics of cross-cultural hermeneutics, such as differences between Chinese and (...) Western concepts of man's relation to the universe, human rights, self and community, good and evil, and beauty. In some of the contributions attempts are made to adapt the Chinese philosophical inheritance to the modern or post-modern condition. A useful reference for all those - historians of ideas, political scientists, and China watchers alike - who want to understand the dynamics of the cultural flow between East and West and the significance of Chinese thought in a global context.

Die Arbeit fragt den Anfangen psychologischer Begriffsbildung nach: In den Bestimmungen der Asthetik um 1800 stellt sich der Gestaltbegriff als Einheit von Form und Inhalt, von Begriff und Natur solchermassen vor, dass erkennendes Subjekt und Erscheinungswelt versohnt scheinen; jene, von Kants -asthetischer Urteilskraft- sich herleitende Illusion erscheint in ihrer asthetisch-naturphilosophischen (Goethe-Schelling-Carus) und psychologisch-asthetischen Version (Reinhold-Fichte-Schiller-Niethammer) in einem jeweils entsprechenden Begriff erzieherisch-vorauszusetzender menschlicher Natur und figuriert in - individuelles Verhalten und die Gesetze der Natur versohnenden- Bildern -subjektiver Totalitat-.".

Pohl (Chinese studies, Trier U., Germany) and Muller (philosophy, Trier U.) present 16 contributions penned by U.S., German, Taiwanese, and Chinese scholars that explore the ethical viewpoints of their respective philosophical traditions. The collection is meant to be cross-cultural at the same time as it attends to the political/ideological rifts of the Western and Chinese regions. After exploring theoretical issues of understanding ethics in a global context, the contributors explore ethical and political values for Chinese and Western societies respectively. Final (...) papers offer a more explicitly comparative approach, looking at such ideas as morality and the family, medical ethics, and jurisprudential attitudes towards human rights.

The chronological proximity of the Marburg neo-Kantian school and Edith Stein's phenomenological philosophy, and - related to this - the existence of common philosophical problems allow us to approach the question of the relationship between Edith Stein and the Marburg neo-Kantian school not looking for similarities, but rather comparing the points of view of Edith Stein and Paul Natorp (the author chosen to represent this School) on the same problems.
