TY - JOUR A1 - Enzingmüller, Carolin A1 - Prechtl, Helmut T1 - Constructing graphs in biology class BT - Secondary biology teachers’ beliefs, motivation, and self-reported practices JF - International journal of science and mathematics education N2 - There has been a growing awareness that graphing is an essential part of the science curriculum. While much research has focused on student conceptions and abilities regarding graphical representations, only few studies have investigated what teachers think about them and how they use graphs in science class. The purpose of this study is to explore educational beliefs, motivation, and teaching practices of German secondary biology teachers regarding graph construction. Via questionnaire surveys, 71 teachers from different regions in Germany rated their beliefs and motivation as well as the frequency of different graph construction activities in biology class. The teachers surveyed in this study were quite motivated in their teaching of graph construction. Furthermore, they tended to believe that graph construction should be practiced explicitly in biology class and that students should learn clear strategies for constructing graphs. We found that teaching subjects and own research experience make a difference in teachers' beliefs and motivation regarding graph construction in biology class. The self-report on classroom practices revealed that participants may provide limited opportunities for students to experience graphing as a social and iterative practice. Implications are drawn for teacher education and professional development as well as for further research in teacher education contexts.

It addresses the semantic domains present in pseudonyms in a corpus of 19th-century Irish English threatening notices and their cognitive functions in the construction of both cultural-contextualised threat and the threatener's identity. We identify eight semantic domains that are accessed recurrently in order to create threat. Contributing to the notion of threat involves menacing war, violence, darkness and perdition directly, while also constructing a certain persona for the threatener that highlights their motivation, moral superiority, historical, local and circumstantial expertise, and their physical and mental aptitude. We argue that pseudonyms contribute to the deontic force of the threat by accessing cultural categories and schemas as well as conceptual metaphors and metonymies. Finally, we suggest that pseudonyms function as post-positioned semantic frame setters, providing a cognitive lens through which the entire threatening notice must be interpreted.

CY - Amsterdam ER - TY - JOUR A1 - Bauer, Hartmut A1 - Meier, Michael T1 - Green Light for PPP on German Motorways? JF - Frontiers of law in China N2 - While public–private partnerships (PPPs) have surged worldwide since the 1990s, they have been met with growing skepticism during the last years. A recent revision of Germany’s constitutional rules on motorway construction and observations on the use of PPPs published by both the German and the European Courts of Auditors illustrate this new caution. These two examples fit into a general trend towards a revival of the public sector, which can be summarized under the cross-level umbrella term “publicization.” It would, however, be remiss to replace the uncritical euphoria that once surrounded privatization with a similarly undifferentiated euphoria regarding publicization. Rather, it is crucial to identify the most appropriate solution for the fulfilment of each public task from the “toolbox” of publicization on the one hand and privatization on the other hand in order to ensure the most effective completion of public functions.

The key step of the synthesis is an acetalisation reaction. In previous years we used acetalisation reactions extensively to build up various molecular rods. Based on this approach, investigations towards porous polymeric materials were conducted by us. Here we wish to present the results of these studies in the synthesis of 1D polyacetals and porous 3D polyacetals. By scrambling experiments with 1D acetals we could prove that exchange reactions occur between different building blocks (evidenced by MALDI-TOF mass spectrometry). Based on these results we synthesized porous 3D polyacetals under the same mild conditions.
