Aiming a better coordination among these three parts of teacher education at university, many of the supported projects have designed and realized university-specific approaches. This conference proceedings volume comprises contributions by 15 of these projects. Seven of those were introduced and discussed in workshops on the occasion of two cross-regional project-conferences in Hannover and Potsdam. Overall, the contributions give a theoretically funded as well as a practice-oriented overview of current approaches and concepts to achieve a better connection between study units concerning studies in content knowledge, pedagogical content knowledge and pedagogical knowledge in teacher education. The volume presents university projects, which take effect on different levels (at the level of curriculum and content, at a collegiate level, at the level of structural conditions of universities). The different approaches are described in a way that they can provide a basis for transfer to other subjects or further universities. The contributions are aimed at teacher educators as well as other actors working in the field of teaching- and quality development at universities. All of them can take transferable ideas and impulses from the described concepts and formats.}, language = {de} } @article{CasseShkilnyyLindersetal.2012, author = {Casse, Olivier and Shkilnyy, Andriy and Linders, J{\"u}rgen and Mayer, Christian and H{\"a}ussinger, Daniel and V{\"o}lkel, Antje and Th{\"u}nemann, Andreas F. and Dimova, Rumiana and C{\"o}lfen, Helmut and Meier, Wolfgang P. and Schlaad, Helmut and Taubert, Andreas}, title = {Solution behavior of double-hydrophilic block copolymers in dilute aqueous solution}, series = {Macromolecules : a publication of the American Chemical Society}, volume = {45}, journal = {Macromolecules : a publication of the American Chemical Society}, number = {11}, publisher = {American Chemical Society}, address = {Washington}, issn = {0024-9297}, doi = {10.1021/ma300621g}, pages = {4772 -- 4777}, year = {2012}, abstract = {The self-assembly of double-hydrophilic poly(ethylene oxide)-poly(2-methyl-2-oxazoline) diblock copolymers in water has been studied. Isothermal titration calorimetry, small-angle X-ray scattering, and analytical ultracentrifugation suggest that only single polymer chains are present in solution. In contrast, light scattering and transmission electron microscopy detect aggregates with radii of ca. 100 nm. Pulsed field gradient NMR spectroscopy confirms the presence of aggregates, although only 2\% of the polymer chains undergo aggregation. Water uptake experiments indicate differences in the hydrophilicity of the two blocks, which is believed to be the origin of the unexpected aggregation behavior (in accordance with an earlier study by Ke et al. [Macromolecules 2009, 42, 5339-5344]). The data therefore suggest that even in double-hydrophilic block copolymers, differences in hydrophilicity are sufficient to drive polymer aggregation, a phenomenon that has largely been overlooked or ignored so far.}, language = {en} } @article{GimbelZiepprechtMayer2018, author = {Gimbel, Katharina and Ziepprecht, Kathrin and Mayer, J{\"u}rgen}, title = {{\"U}berzeugungen angehender Lehrkr{\"a}fte fachspezifisch und inhaltsspezifisch operationalisieren und erfassen}, series = {Koh{\"a}renz in der universit{\"a}ren Lehrerbildung}, journal = {Koh{\"a}renz in der universit{\"a}ren Lehrerbildung}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-86956-438-8}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-418614}, pages = {179 -- 198}, year = {2018}, language = {de} } @article{JansenBuschmannWegoetal.2001, author = {Jansen, K. and Buschmann, Hans-J{\"u}rgen and Wego, A. and Dopp, D. and Mayer, C. and Holdt, Hans-Joachim and Schollmeyer, E.}, title = {Curcubit[5]uril, decamethylcururbit[5]uril and curcurbit[6]uril : synthesis, solubility and amin complex formation}, year = {2001}, abstract = {A simple way to prepare cucurbit[5]uril is described. The macrocycles of the cucurbituril type are nearly insoluble in water. The solubilities of cucurbit[5]uril, decamethylcucurbit[5]uril and cucurbit[6]uril in hydrochloric acid, formic acid and acetic acid of different concentrations have been investigated. Due to the formation of complexes between cucurbit[n]urils and protons the solubility increases in aqueous acids. The macrocyclic ligands are able to form complexes with several organic compounds. Thus, the complex formation of the cucurbituril macrocycles with different amines has beenstudied by means of calorimetric titrations. The reaction enthalpy gives noevidence of the formation of inclusion or exclusion complexes. 1H-NMR measurements show that in the case of cucurbit[5]uril and cucurbit[6]uril the organic guest compound is included within the hydrophobic cavity. Decamethylcucurbit[5]uril forms only exclusion complexes with organicamines. This was confirmed by the crystal structure of the decamethylcucurbit[5]uril-1,6- diaminohexane complex. complex formation - cucurbit[5]uril - cucurbit[6]uril - decamethylcucurbit[5]uril - solubility - synthesis}, language = {en} } @misc{KochCasselLinneetal.2017, author = {Koch, Sarah and Cassel, Michael and Linne, Karsten and Mayer, Frank and Scharhag, J{\"u}rgen}, title = {ECG and echocardiographic findings in 10-15-year-old elite athletes}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-403186}, pages = {8}, year = {2017}, abstract = {Background: Data on electrocardiographic and echocardiographic pre-participation screening findings in paediatric athletes are limited. Methods and results: 10-15 year-old athletes (n = 343) were screened using electro- and echocardiography. The electrocardiogram (ECG) was normal in 220 (64\%), mildly abnormal in 108 (31\%), and distinctly abnormal in 15 (4\%) athletes. Echocardiographic upper reference limits (URL, 97.5 percentile) for the left ventricular (LV) wall thickness in 10-11-year-old boys and girls were 9-10 mm and 8-9 mm, respectively; in 12-13-year-old boys and girls 9-10 mm; and in 14-15-year-old boys and girls 10-11 mm and 9-10 mm, respectively. Three athletes were excluded from competitive sports: one for symptomatic Wolff-Parkinson-White syndrome with a normal echocardiogram; one for negative T-waves in V-1-V-4 and a dilated right ventricle by echocardiography suggestive of (arrhythmogenic) right ventricular disease; and one for normal ECG and biscupid aortic valve including an aneurysm of the ascending aorta detected by echocardiography. Related to echocardiographic findings, the sensitivity and specificity of the ECG to identify cardiovascular abnormalities was 38\% and 64\%, respectively. The ECG's positive-predictive and negative-predictive values were 13\% and 88\%, respectively. The numbers needed to screen and calculated costs were 172 for ECG ( 7049), 172 for echocardiography ( 11,530), and 114 combining ECG and echocardiography ( 9323). Conclusions: Compared to adults, paediatric athletes presented with fewer distinctly abnormal ECGs, and there was no gender difference in paediatric athletes' ECG-pattern distribution. A combination of ECG and echocardiography for pre-participation screening of paediatric athletes is superior to ECG alone but 30\% more costly.}, language = {en} } @article{KochCasselLinneetal.2014, author = {Koch, Sarah and Cassel, Michael and Linne, Karsten and Mayer, Frank and Scharhag, J{\"u}rgen}, title = {ECG and echocardiographic findings in 10-15-year-old elite athletes}, series = {European journal of preventive cardiology : the official ESC journal for primary \& secondary cardiovascular prevention, rehabilitation and sports cardiology}, volume = {21}, journal = {European journal of preventive cardiology : the official ESC journal for primary \& secondary cardiovascular prevention, rehabilitation and sports cardiology}, number = {6}, publisher = {Sage Publ.}, address = {London}, issn = {2047-4873}, doi = {10.1177/2047487312462147}, pages = {774 -- 781}, year = {2014}, abstract = {Background: Data on electrocardiographic and echocardiographic pre-participation screening findings in paediatric athletes are limited.}, language = {en} } @book{KurthsMayerKress1998, author = {Kurths, J{\"u}rgen and Mayer-Kress, Gottfried}, title = {Nonlinear analysis of physiological data}, editor = {Kantz, Holger}, publisher = {Springer}, address = {Berlin, New York}, isbn = {3-540-63481-9}, pages = {VIII, 344 S. : Ill., graph.
