Der Tiroler Freiheitskampf 1809 mit besonderer Berücksichtigung der Frauen zu dieser Zeit

Die vorliegende Diplomarbeit beleuchtet den „Tiroler Freiheitskampf“ mit spezifischer Sicht auf die Frauen. Als zentrale Themen wurden die gesellschaftliche Situation der Frauen zur Zeit der Kampfhandlungen, sowie die Darstellungen dieser in der bildenden Kunst untersucht. Zu betonen ist, dass sich der Lebensalltag der Frauen stark veränderte, als ihre Männer und Söhne in den Krieg zogen. Sie übernahmen die Verantwortung für Familie und Hof und versuchten die Arbeit der abwesenden Männer zu erledigen. Ebenso gibt es genügend Erzählungen von Frauen, die sich indirekt am Kampfgeschehen beteiligten, indem sie Verwundete pflegten oder die Schützen mit Essen und Trinken versorgten. Jedoch gibt es nur sehr wenige zeitgenössische Quellen, welche diese Darstellungen, die auch in vielen Bildern übermittelt werden, belegen. Dasselbe gilt für jene Geschichten, die von kämpfenden Frauen berichten. Es gibt mehrere Schilderungen von Frauen, die sich aktiv am Kampf gegen die Bayern dadurch beteiligten, dass sie Brücken abtrugen, die Bayern mit Steinlawinen überraschten oder bewaffnet an der Front standen und kämpften. Der Großteil dieser Geschichten und die bildlichen Darstellungen, die es davon gibt, können allerdings weitgehend dem Reich der Mythen zugeschrieben werden, da es kaum Belege für diese Ereignisse gibt

Upper-to-lower limb coordination dynamics in swimming depending on swimming speed and aquatic environment manipulations

Swimming is a challenging locomotion, involving the coordination of upper and lower limbs to propel the body forward in a highly resistive aquatic environment. During front crawl, freestyle stroke, alternating rotational motion of the upper limbs above and below the waterline, is coordinated with alternating lower limb pendulum actions. The aim of this study was to investigate the upper to lower limbs coordination dynamics of eight male elite front crawlers while increasing swimming speed and disturbing the aquatic environment (i.e., pool vs. flume). Upper to lower limb frequency ratios, coordination, coupling strength, and asymmetry were computed from data collected by inertial measurement units. Significant speed effect was observed, leading to transitions from 1∶1 to 1∶3 frequency ratios (1∶3 overrepresented), whereas 1∶2 frequency ratio was rarely used. Flume swimming led to a significant lower coupling strength at low speeds and higher asymmetries, especially at the highest speeds, probably related to the flume dynamic environment

Witte Swaen from 1636: the discovery and archaeological survey of an intact fluit in the Gulf of Finland, Baltic Sea

In 2020, the diving group Badewanne discovered an exceptionally well-preserved wreck in the Gulf of Finland, Baltic Sea. Researchers and divers from several different institutions collaborated to survey the wreck with the ambition of gathering as much archaeological information with as little impact on the wreck as possible. This paper summarizes the current state of research and argues that the wreck is the remains of a merchant fluit loaded with grain. Archival research has identified the ship as Witte Swaen, built in 1636 and sunk in 1638. Besides highlighting the fate of this particular fluit, the survey has revealed the characteristic hull shape as well as the sculptural decorations, which diverge from other later archaeologically surveyed fluits in the Baltic.Archaeological Heritage Managemen

Testing Multiple Coordination Constraints with a Novel Bimanual Visuomotor Task

The acquisition of a new bimanual skill depends on several motor coordination constraints. To date, coordination constraints have often been tested relatively independently of one another, particularly with respect to isofrequency and multifrequency rhythms. Here, we used a new paradigm to test the interaction of multiple coordination constraints. Coordination constraints that were tested included temporal complexity, directionality, muscle grouping, and hand dominance. Twenty-two healthy young adults performed a bimanual dial rotation task that required left and right hand coordination to track a moving target on a computer monitor. Two groups were compared, either with or without four days of practice with augmented visual feedback. Four directional patterns were tested such that both hands moved either rightward (clockwise), leftward (counterclockwise), inward or outward relative to each other. Seven frequency ratios (3∶1, 2∶1, 3∶2, 1∶1, 2∶3. 1∶2, 1∶3) between the left and right hand were introduced. As expected, isofrequency patterns (1∶1) were performed more successfully than multifrequency patterns (non 1∶1). In addition, performance was more accurate when participants were required to move faster with the dominant right hand (1∶3, 1∶2 and 2∶3) than with the non-dominant left hand (3∶1, 2∶1, 3∶2). Interestingly, performance deteriorated as the relative angular velocity between the two hands increased, regardless of whether the required frequency ratio was an integer or non-integer. This contrasted with previous finger tapping research where the integer ratios generally led to less error than the non-integer ratios. We suggest that this is due to the different movement topologies that are required of each paradigm. Overall, we found that this visuomotor task was useful for testing the interaction of multiple coordination constraints as well as the release from these constraints with practice in the presence of augmented visual feedback

Laterally focused attention modulates asymmetric coupling in rhythmic interlimb coordination.

Peters (J Motor Behav 21:151-155, 1989; Interlimb coordination: neural, dynamical and cognitive constraints, Academic, Orlando, pp 595-615, 1994) suggested that expressions of handedness in bimanual coordination may be reflections of an inherent attentional bias. Indeed, previous results indicated that focusing attention on one of the limbs affected the relative phasing between the limbs in a manner comparable to the effects of hand dominance. The present study extended the comparison between the effects of attentional focus and handedness by testing their impact on the interactions between the limbs. Both left-handed and right-handed participants performed rhythmic bimanual coordination tasks (in-phase and antiphase coordination), while directing attention to either limb. Using brief mechanical perturbations, the degree to which the limbs were influenced by each other was determined. The results revealed that the non-dominant limb was more strongly affected by the dominant limb than vice versa and that, in line with Peters' proposition, this handedness-related asymmetry in coupling strength was reduced when attention was focused on the non-dominant limb, thereby highlighting the potential relation between inherent (handedness-related) asymmetries and voluntary attentional asymmetries. In contrast to previous findings, the (commonly observed) phase lead of the dominant limb was attenuated (rather than accrued) when attention was focused on this limb. This unexpected result was explained in terms of the observed attention-related difference in amplitude between the limbs. © 2006 Springer-Verlag

Bilateral motor unit synchronization is functionally organized.

To elucidate the neural interactions underlying bimanual coordination, we investigated in 11 participants the bilateral coupling of homologous muscles in an isometric force production task involving fatiguing elbow flexion and extension. We focused on changes in motor unit (MU) synchronization as evident in EMG recordings of relevant muscles. In contrast to a related study on leg muscles, the arm muscles did not exhibit MU synchronization around 16 Hz, consistent with our hypothesis that 16 Hz MU synchronization is linked to balance maintenance. As expected, bilateral MU synchronization was apparent between 8 and 12 Hz and increased with fatigue and more strongly so for extensor than for flexor muscles. MU synchronization in that frequency band is interpreted in terms of common bilateral input and substantiates the idea that common input is functionally organized. Since these findings are consistent with the literature on mirror movements, they suggest that both phenomena may be related. © 2006 Springer-Verlag
