Struktur, Prozess, Diskurs: Vorüberlegungen zu einer strukturellen Curriculumtheorie, Berlin 1973. Mit der Wolfgang Edelstein Memorial Lecture 2022
No full textIn this previously unpublished text, Wolfgang Edelstein has presented systematic “Preliminary Considerations for a Structural Curriculum Theory,” guided by three concepts that organize the factual and temporal-social references as well as the mode of justification of the school as a place of subject-bound instruction. In 1973, when he presented these considerations, the great dream of a comprehensive educational reform based on the comprehensive school had been shattered, which had been nurtured by the German Education Council and also pushed by the MPI for Human Development, as Edelstein soberly and critically balances at the beginning. In addition, the great promises of the various curriculum theories had come to an end, including the theory of the MPI director Saul B. Robinsohn, which was oriented toward the analysis of social need. Edelstein’s new approach was oriented toward the goal of enabling every learner to achieve self-determination in a civilization determined by the sciences, and perceived the educational system primarily as a world of learning that shapes school learning processes in their factual-temporal logic in a subject-centered way. It is thus a decidedly content- and process-oriented rather than an outcome-oriented view of schooling that he makes the central reference for theoretical work and the criterion for the design of learning processes. Learning and social psychological theories are therefore particularly intensively received, above all Jean Piaget and considerations concerning the “structure of discipline,” with which Jerome Bruner had newly inspired the teaching-related debate

One Analytical Approach of Rashba-Edelstein Magnetoresistance in 2D Materials
No full textWe study analytically the Rashba-Edelstein magnetoresistance (REMR) in a
structure made from an insulator ferromagnet, such as yttrium iron garnet
(YIG), and a 2D material (2DM) with direct and inverse Rashba-Edelstein
effects, such as SLG and MoS. Our results represent an efficient way of
analyzing the Rashba-Edelstein effects

Nowe spojrzenie na planowanie architektury mieszkaniowej w afryce subsaharyjskiej
No full textThe author shares his reflections on state of art in housing and urban planning, deficiencies, expectations and possibilities in the Sahel region of Africa. He notices, that the housing problem in Africa is one of the challenges, which should be solved in order to recover life dignity of African people and secure their rights to traditional family life in acceptable conditions. The paper describes the studies on the typical dispersed urban structures and the need to foster this type of settlement structure and proposals of introduction of new on light steel frame housing system in the area of Sahel, combining the traditional way of building houses with modern technology. The particularly analysed case, is the housing problem in the Republic of Chad. The author presents the basic discussion on this topic and his architectural proposals. Unfortunately, the gap between the needs and the financial feasibility of housing construction in this area, makes this project already at the starting point extremely difficult to be realized without external subventions.Problem mieszkaniowy w Afryce jest jednym z wyzwań, które należy rozwiązać, aby Afrykanie mogli odzyskać godność życiową i zabezpieczyć swoje prawa do tradycyjnego życia rodzinnego w akceptowalnych warunkach. W artykule opisano badania nad typowymi rozproszonymi strukturami miejskimi i potrzebą wspierania tego typu struktur osadniczych oraz propozycji wprowadzenia nowego systemu konstrukcji domów, opartym na lekkim szkielecie stalowym, łączącym tradycyjny sposób budowania domów z nowoczesną technologią. Przypadkiem szczególnie analizowanym jest problem mieszkaniowy w Republice Czadu. Autor przedstawia podstawową dyskusję na ten temat i swoje propozycje architektoniczne. Niestety luka między potrzebami mieszkaniowymi w Czadzie a finansową wykonalnością budownictwa mieszkaniowego w tym obszarze sprawia, że projekt ten, już w punkcie wyjścia, jest niezwykle trudny do realizacji bez uzyskania zewnętrznych dotacji
Spin injection and inverse Edelstein effect in the surface states of topological Kondo insulator SmB6
No full textThere has been considerable interest in exploiting the spin degrees of freedom of electrons for potential information storage and computing technologies. Topological insulators (TIs), a class of quantum materials, have special gapless edge/surface states, where the spin polarization of the Dirac fermions is locked to the momentum direction. This spin-momentum locking property gives rise to very interesting spin-dependent physical phenomena such as the Edelstein and inverse Edelstein effects. However, the spin injection in pure surface states of TI is very challenging because of the coexistence of the highly conducting bulk states. Here, we experimentally demonstrate the spin injection and observe the inverse Edelstein effect in the surface states of a topological Kondo insulator, SmB6. At low temperatures when only surface carriers are present, a clear spin signal is observed. Furthermore, the magnetic field angle dependence of the spin signal is consistent with spin-momentum locking property of surface states of SmB6.National Basic Research Programs of China (973 program) [2014CB920902, 2015CB921104, 2013CB921903]; National Natural Science Foundation of China (NSFC) [11574006, 11374020]; Strategic Priority Research Program of the Chinese Academy of Sciences [XDB04040100]; DOE BES Award [DEFG02-07ER46351]; 1000 Talents Program for Young Scientists of ChinaSCI(E)[email protected]; [email protected]; [email protected]
