TY - JOUR A1 - Müller, Tom T1 - Roger Bacon in der Sicht Alexander von Humboldts JF - Alexander von Humboldt im Netz ; international review for Humboldtian studies N2 - In seiner sechsstufigen Epochengliederung der Wissenschaftsgeschichte sieht Alexander von Humboldt nur wenige Lichter, welche die abendländische Dunkelheit der Zeit zwischen der wissenschaftlichen Blüte im arabischen Raum und den Entdeckungsfahrten des Columbus durchbrechen. Als den wichtigsten dieser wenigen Wegbereiter hebt der Freiherr den Franziskanermönch Roger Bacon hervor, der sich in fast allen Disziplinen hervorgetan und für die Einheit der Wissenschaften eingesetzt habe. Nicht nur im Kosmos, sondern auch bereits in den populären Vorträgen in der Singakademie und den Kritischen Untersuchungen zur Geschichte der Geographie der Neuen Welt würdigt Humboldt den Engländer durch ausführliche Auseinandersetzungen mit dessen Opus maius. N2 - In his model of the six epochs of the history of science, Alexander von Humboldt sees scarcely any lights able to break through the occidental darkness in the time between the scientific prime of the arabic world and the expeditions of Columbus. The most prominent of these few pioneers to Humboldt is the fransciscan monc Roger Bacon who excelled in almost all disciplines and emphasized on the unity of the sciences. Humboldt honors the Englishman with detailed examinations of his Opus maius in Kosmos and also in his popular speeches in the Berlin Singakademie as well as in the examen critique on the history of geography of the New World. N2 - En su clasificación en seis etapas de las épocas de la historia de la ciencia Alexander von Humboldt ve pocas luces que quiebren el oscurecimiento de Occidente durante el tiempo que media entre el florecimiento científico en el ámbito árabe y los viajes de Colón. El Barón señala al monje franciscano Roger Bacon como a uno de aquellos precursores más importantes, destacado en casi todas las disciplinas y esforzado en la unidad de la ciencia. Humboldt reconoce al inglés por medio de detalladas discusiones con su Opus maius, no sólo en Kosmos, sino ya en las conferencias populares de la Singakademie y en las Investigaciones Críticas de historia de la geografía del nuevo mundo.

This study investigates how German 4-year-old children comprehend sentences with the focus particle ‘nur’ (only) by using different tasks and controlling for the impact of general cognitive abilities on performance measures. Two sentence types with ‘only’ in either pre-subject or pre-object position were presented. Eye gaze data and verbal responses were collected via the visual world paradigm combined with a sentence-picture verification task. While the eye tracking data revealed an adult-like pattern of focus particle processing, the sentence-picture verification replicated previous findings of poor comprehension, especially for ‘only’ in pre-subject position. A second study focused on the impact of general cognitive abilities on the outcomes of the verification task. Working memory was related to children’s performance in both sentence types whereas inhibitory control was selectively related to the number of errors for sentences with ‘only’ in pre-subject position. These results suggest that children at the age of 4 years have the linguistic competence to correctly interpret sentences with focus particles, which–depending on specific task demands–may be masked by immature general cognitive abilities.

Drop jumps and landings were assessed on a force plate under stable and unstable (balance pad on top of the force plate) conditions. Performance measures (contact time, jump height, peak ground reaction force) and electromyographic (EMG) activity of leg and trunk muscles were tested in 27 subjects (age 23 +/- A 3 years) during different time intervals (preactivation phase, braking phase, push-off phase). The performance of drop jumps under unstable compared to stable conditions produced a decrease in jump height (9 %, p < 0.001, f = 0.92) and an increase in peak ground reaction force (5 %, p = 0.022, f = 0.72), and time for braking phase (12 %, p < 0.001, f = 1.25). When performing drop jumps on unstable compared to stable surfaces, muscle activity was reduced in the lower extremities during the preactivation, braking and push-off phases (11-25 %, p < 0.05, 0.48 a parts per thousand currency sign f a parts per thousand currency sign 1.23). Additionally, when landing on unstable compared to stable conditions, reduced lower limb muscle activities were observed during the preactivation phase (7-60 %, p < 0.05, 0.50 a parts per thousand currency sign f a parts per thousand currency sign 3.62). Trunk muscle activity did not significantly differ between the test conditions for both jumping and landing tasks. The present findings indicate that modified feedforward mechanisms in terms of lower leg muscle activities during the preactivation phase and/or possible alterations in leg muscle activity shortly after ground contact (i.e., braking phase) are responsible for performance decrements during jumping on unstable surfaces.

In this regard, there is a gap in the literature to which extent sprint interval training (SIT) can enhance cognitive performance. Thus, this study aimed to investigate the effect of a time-efficient SIT, termed as "shortened-sprint reduced-exertion high-intensity interval training" (SSREHIT), on cognitive performance. Nineteen healthy adults aged 20-28 years were enrolled and assessed for attentional performance (via the d2 test), working memory performance (via Digit Span Forward/Backward), and peripheral blood lactate concentration immediately before and 10 min after an SSREHIT and a cognitive engagement control condition (i.e., reading). We observed that SSREHIT can enhance specific aspects of attentional performance, as it improved the percent error rate (F%) in the d-2 test (t (18) = -2.249, p = 0.037, d = -0.516), which constitutes a qualitative measure of precision and thoroughness. However, SSREHIT did not change other measures of attentional or working memory performance. In addition, we observed that the exercise-induced increase in the peripheral blood lactate levels correlated with changes in attentional performance, i.e., the total number of responses (GZ) (r(m) = 0.70, p < 0.001), objective measures of concentration (SKL) (r(m) = 0.73, p < 0.001), and F% (r(m) = -0.54, p = 0.015). The present study provides initial evidence that a single bout of SSREHIT can improve specific aspects of attentional performance and conforming evidence for a positive link between cognitive improvements and changes in peripheral blood lactate levels.
