Yet with the large range of individual factors, this is not a one-size-fits-all proposition. This study of L2 Technical English students at two German universities explored learners’ expectations and motivations, in particular regarding self-regulation and self-efficacy via the individual’s time investment in self-led study. In an initial survey, learners (N=1646) reported on their English skill levels and anticipated learning habits. Complementarily, the retrospective survey investigated learners’ (N=796) actual behavior during the course, their perceptions of language skill improvement, and their satisfaction. The initial survey indicates a clear understanding that time investment in self-regulated study will lead to greater improvement, an outcome confirmed in the retrospective survey. Additionally, students who invested more time in their coursework were more satisfied with their achievement, although most learners acknowledge they should have studied more. The results verify that learners recognize the nexus between self-regulation and language skill improvement, yet university students are not satisfied with their capacity to self-regulate their language learning strategies. While differences in students’ skill levels and academic self-efficacy result in divergent degrees of progress, students of all types report benefits to their language skills when motivated to self-regulated study.

The Foster Canonical network synthesis technique with two RLC tanks has been employed to generate the two resonant bands of the antenna. The transfer function model is subsequently refined using a data fitting algorithm (viz the Nelder-Mead simplex algorithm). Parametric adjustments are performed at the final stage in order to further improve the accuracy of the final parameters.

The goal of the proposed magnet system is to minimize the coil-current effect and to optimize the shielding at the same time. In the proposed design, a permanent magnet system with two gaps, each housing a coil, is employed to minimize the coil current effect, by reducing the linear coil-current dependence reported for the single air gap design by at least one order of magnitude. Both air gaps of the magnet are completely surrounded by high-permeability material, and hence the coils are shielded from outside magnetic fields and no magnetic field leaks outside of the magnet system. An example of the new magnet system is given and the analysis shows that the magnetic field in the air gap can be optimized to meet the requirement to be used in Kibble balances.

Since standard silicon semiconductor technology has been used for the fabrication, they may be easily integrated with other silicon based circuits and devices on the same chip. The silicon tip geometry and the operating conditions were optimized in order to obtain highly uniform and stable electron field emission from large area cathode arrays. A series of uniform hexagonal tip arrays containing each 547 tips were fabricated and characterized. The electron emission properties of both individual tips as well as of complete emitter arrays were investigated. A saturation level in the voltage-current characteristics was found, which can be explained by the limitation of the supply of electrons due to the p-type silicon wafer material. When operating the arrays in the current saturation regime at an emission current of ~ 1 nA per tip, a highly stable and low noise emission can be observed.

T1 - Directed Self-Assembly of Ge Quantum Dots Using Focused Si2+ Ion Beam Patterning JF - scientific reports N2 - We show that templating a Si surface with a focused beam of Si2+ or Si+ ions can create suitable nucleation sites for the subsequent growth of self-assembled Ge quantum dots by chemical vapor deposition. To determine the mechanism of patterning we use atomic force microscopy to show that, similar to Ga+ patterning, the formation of a surface pit is required to enable control over Ge quantum dot locations. We find that relatively high implantation doses are required to achieve patterning, and these doses lead to amorphization of the substrate. We assess the degree to which the substrate crystallinity can be recovered by subsequent processing. Using in situ transmission electron microscopy heating experiments we find that recrystallization is possible at the growth temperature of the Ge quantum dots, but defects remain that follow the pattern of the initial implantation. We discuss the formation mechanism of the defects and the benefits of using Si ions for patterning both defects and quantum dots on Si substrates.

Hierzu zählt auch die Kassenärztliche Bundesvereinigung (KBV), die im Jahr 2006 die Forschungsgruppe Wahlen Telefonfeld (FGW) in Mannheim beauftragte, repräsentativ gesetzlich und privat Versicherte zur Zufriedenheit mit der ambulanten Versorgung sowie zum Bedarf an neuen Dienstleistungsangeboten zu befragen (KBV 2006; Rieser 2006). Eine zweite Versichertenbefragung der KBV erfolgte im Zeitraum Mai und Juni 2008, wiederum von der FGW durchgeführt. Die Ergebnisse dieser repräsentativen Erhebung werden im Rahmen von zwei Artikeln in Gesundheits- und Sozialpolitik vorgestellt. Im Zentrum des hier vorliegenden ersten Beitrags stehen die Inanspruchnahme der ambulanten haus- und fachärztlichen Versorgung, die Erfahrungen mit Terminvergabe und Wartezeiten sowie die Bewertungen der Versorgung durch die Versicherten. Darüber hinaus wird die Bedeutung von Individuellen Gesundheitsleistungen (IgeL) in der ambulanten Versorgung gesetzlich Versicherter diskutiert. Der zweite Artikel wird sich schwerpunktmäßig mit den Qualitätskriterien für die Wahl eines Arztes, mit den Erfahrungen von Veränderungen in der Medikamentenverordnung sowie mit der Akzeptanz neuer Versorgungsformen und Wahltarife befassen.
