193. De Vries, Simon (1633/34-1667)
No full textSimon Joosten de Vries was an Amsterdam Mennonite merchant, born in 1633 or 1634. He died a bachelor on September 17, 1667 and according to several reports, Spinoza inherited an annual sum from his estate, allowing him to fully concentrate on his work as a philosopher. Unlike his friends Jarig Jelles, to whom he was related by family ties, and Pieter Balling, De Vries was not a published author, but like them he belonged to Spinoza’s most intimate acquaintances, as is evident not only from his last will, but most of all from the letters Spinoza and De Vries exchanged once the philosopher had left Amsterdam
Brain Power: The role of psychology in energy transitions
No full textIn this webinar, TU Delft climate psychologist Gerdien de Vries explains why and how psychological perspectives, theory and methods are useful for energy transitions. Energy transitions imply changes in the behaviour of all actors involved. For example, citizens and organisations need to accept and use new energy technologies, policymakers have to design effective policies, and industries and researchers need to push for both technological and social innovations. Behavioural change in energy transitions is difficult to accomplish though. Psychological mechanisms, such as habits, hassles, and heuristics are identified as important barriers. Therefore, interest in psychology is growing among stakeholders dealing with energy transitions. This interest is visible in the emergence of behavioural or “nudge” units within governmental, civic, and commercial organizations. But despite this emergence, the integration of psychology in the broader energy system is relatively underdeveloped in literature and public policy alike. Dr. de Vries calls for a change.Organisation & Governanc

No full textKlimaatpsycholoog Gerdien de Vries werkt aan de TU Delft en doet al 10 jaar onderzoek naar het gedoe dat mensen ervaren als ze hun woning willen verduurzamen.
