  abstract  = {Die Lebensgeschichte des j{\"u}dischen Gelehrten und Aufkl{\"a}rers Moses Mendelssohn (1729-1786), der allen Hindernissen zum Trotz in den Rang einer allseits anerkannten intellektuellen Autorit{\"a}t aufstieg, wurde innerhalb der Geschichte des deutschen Judentums zum Inbegriff einer individuellen Emanzipation im Medium der Bildung. Mendelssohns Vita fand ein theoretisches Pendant in seiner Philosophie der Bestimmung des Menschen zu einer unaufh{\"o}rlichen Vervollkommnung. Beide Str{\"a}nge dieser f{\"u}r anthropologische Fragestellungen sensiblen, lebenspraktisch relevanten Metaphysik - das Nachdenken {\"u}ber eine allgemeing{\"u}ltige Bestimmung des Menschen auf der einen und die Reflexion {\"u}ber eine spezifisch j{\"u}dische Existenz auf der anderen Seite - erschließen die universelle und partikulare Dimension des menschlichen Lebens und ergeben in ihrer Verbindung ein theoretisches Integral von allgemeiner Menschennatur und kultureller Partikularit{\"a}t. Am Beispiel des Judentums f{\"u}hrt Mendelssohn die Allgemeing{\"u}ltigkeit des partikularen Anspruchs auf die Bewahrung kultureller Andersartigkeit vor. Sein bestimmungsmetaphysisches Denken gipfelt in einem Pl{\"a}doyer f{\"u}r die Toleranz, welches das geistige Erbe des deutsch-j{\"u}dischen Philosophen ausmacht.},

  abstract  = {Background: It has previously been shown that conditioning activities consisting of repetitive hops have the potential to induce better drop jump (DJ) performance in recreationally active individuals. In the present pilot study, we investigated whether repetitive conditioning hops can also increase reactive jump and sprint performance in sprint-trained elite athletes competing at an international level. Methods: Jump and sprint performances of 5 athletes were randomly assessed under 2 conditions. The control condition (CON) comprised 8 DJs and 4 trials of 30-m sprints. The intervention condition (HOP) consisted of 10 maximal repetitive two-legged hops that were conducted 10 s prior to each single DJ and sprint trial. DJ performance was analyzed using a one-dimensional ground reaction force plate. Step length (SL), contact time (CT), and sprint time (ST) during the 30-m sprints were recorded using an opto-electronic measurement system. Results: Following the conditioning activity, DJ height and external DJ peak power were both significantly increased by 11 \% compared to the control condition. All other variables did not show any significant differences between HOP and CON. Conclusions: In the present pilot study, we were able to demonstrate large improvements in DJ performance even in sprint-trained elite athletes following a conditioning activity consisting of maximal two-legged repetitive hops. This strengthens the hypothesis that plyometric conditioning exercises can induce performance enhancements in elite athletes that are even greater than those observed in recreationally active athletes.. In addition, it appears that the transfer of these effects to other stretch-shortening cycle activities is limited, as we did not observe any changes in sprint performance following the plyometric conditioning activity.},

Education and income had no significant association with intensity. Subjective disability was best predicted by job position, succeeded by the multidimensional index and education, while income again had no significant association.

Das Auftreten solcher grenz{\"u}berschreitender Sachverhalte und deren juristische Begleiterscheinungen sind jedoch nicht ganz unproblematisch, da f{\"u}r die korrekte Besteuerung jener Sachverhalte sowohl das rein nationale Recht als auch die ausl{\"a}ndischen Rechtsgrundlagen beachtet werden m{\"u}ssen. Diese werden in meiner Arbeit detailliert vorgestellt, wobei stets eine Unterscheidung zwischen gemeinschaftsrechtlichen Rechtsgrundlagen, multilateralen, bilateralen und unilateralen Rechtsquellen erfolgt. Zuvor werden die vielf{\"a}ltigen Probleme bei der Besteuerung grenz{\"u}berschreitender Sachverhalte, wie z.B. die Gefahr der Doppelbesteuerung oder der Steuerflucht dargestellt, um danach die nationalen L{\"o}sungsans{\"a}tze, wie die erweiterten Anzeige- und Mitwirkungspflichten auf Seiten der Steuerpflichtigen und den Untersuchungsgrundsatz auf Seiten der Finanzverwaltung aufzuzeigen. Dabei werden die europ{\"a}ischen Grundfreiheiten als Diskriminierungs- und Beschr{\"a}nkungsverbote abgebildet, wobei auch die anerkannten geschriebenen und ungeschriebenen Rechtfertigungsgr{\"u}nde dargestellt werden. Die vielf{\"a}ltigen Auswirkungen des europ{\"a}ischen Prim{\"a}rrechts auf das deutsche Besteuerungsverfahren werden anhand von verschiedenen EuGH-Urteilen veranschaulicht, wobei auch die praktische Umsetzung der europarechtlichen Vorgaben beispielhaft durch das Aktionsprogramm FISCALIS 2020, die Informationszentrale f{\"u}r steuerliche Auslandsbeziehungen in Bonn und das internationale Steuerzentrum in M{\"u}nchen vorgestellt werden.},

  abstract  = {Findings on the perceptual reorganization of lexical tones are mixed. Some studies report good tone discrimination abilities for all tested age groups, others report decreased or enhanced discrimination with increasing age, and still others report U-shaped developmental curves. Since prior studies have used a wide range of contrasts and experimental procedures, it is unclear how specific task requirements interact with discrimination abilities at different ages. In the present work, we tested German and Cantonese adults on their discrimination of Cantonese lexical tones, as well as German-learning infants between 6 and 18 months of age on their discrimination of two specific Cantonese tones using two different types of experimental procedures. The adult experiment showed that German native speakers can discriminate between lexical tones, but native Cantonese speakers show significantly better performance. The results from German-learning infants suggest that 6- and 18-month-olds discriminate tones, while 9-month-olds do not, supporting a U-shaped developmental curve. Furthermore, our results revealed an effect of methodology, with good discrimination performance at 6 months after habituation but not after familiarization. These results support three main conclusions. First, habituation can be a more sensitive procedure for measuring infants' discrimination than familiarization. Second, the previous finding of a U-shaped curve in the discrimination of lexical tones is further supported. Third, discrimination abilities at 18 months appear to reflect mature perceptual sensitivity to lexical tones, since German adults also discriminated the lexical tones with high accuracy.},
