  3. 2. Den akademiska frihetens gränser : Max Weber, Humboldtmodellen och den värdefria vetenskapen

    Författare :Peter Josephson; Tore Frängsmyr; Mats Persson; Ola Agevall; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; History of science and ideas; value-freedom; value judgments; concept of academic freedom; university politics; Humboldt; German University Teacher s Congress; discrimination; Social Democrats; Robert Michels; Idé- och lärdomshistoria; History of science and ideas; Idé- o lärdomshistoria; Idé- och lärdomshistoria; History of Sciences and Ideas;

    Sammanfattning : The aim of this dissertation is to contribute to an understanding of why Weber advocated a value-free science. In en essay from 1917, Weber writes that the question of whether or not one ought to make value judgments in the lecture hall is basically a question of practical university policy. LÄS MER

  4. 3. Studies on hybrid superconducting junctions

    Författare :Cecilia Holmqvist; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Critical Current; Single-Electron Box; Attractive Correlations; Josephson Junction; Negative Charging Energy; Quasiclassical Superconductivity; Josephson Current;

    Sammanfattning : In the field of nanoelectronics, one seeks to combine quantum mechanical effects with macroscopic entities such as currents in order to find new ways of storing and manipulating information. One possibility to accomplish this is to use the quantum correlations found in superconductors. LÄS MER

  5. 4. Attractive Work : Nurses´ work in operating departments, and factors that make it attractive

    Författare :Catrine Björn; Malin Josephson; Barbro Wadensten; Dag Rissén; Lotta Dellve; Uppsala universitet; []
    Nyckelord :attractive work; nursing workforce; personnel turnover; job satisfaction; nurse retention; nurse shortage; operating room; Caring Sciences; Vårdvetenskap;

    Sammanfattning : Background: Previous studies show that nurse retention is one of the most effective strategies to counteract nursing shortages. Few studies have focused on the crucial resource of registered specialist nurses in operating departments. LÄS MER

  7. 5. Interactions and Interference in Mesoscopic Systems: Josephson Current through Quantum Dots and Josephson Junction Arrays

    Författare :Klas Engström; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; density functional theory; quantum dots; Josephson effect; Andreev reflection; mesoscopic superconductivity; Josephson junction array; coulomb interactions; Bogoliubov-de Gennes equation; quantum phase transition;

    Sammanfattning : The focus of the thesis is on the interplay between interactions and interference effects in mesoscopic systems. More specifically, the two main projects included deal with Coulomb interactions and Josephson effect in two superconductor-normal metal systems: (i) a Josephson junction array and (ii) a superconductor-normal metal-superconductor (SNS) system in which the normal part is a quantum dot.
