1. 16. What is going on out there? - What does it mean for children's experiences when the kindergarten is moving their everyday activities into the nature - landscapes and its places

   Författare :Kari-Anne Jørgensen; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Learning; kindergarten; nature; experiences; play; landscapes;

   Sammanfattning : How we understand the practice of learning in nature-landscapes and places is relevant to contemporary environmental arenas, both in the context of international agendas and as an agenda for Nordic kindergartens where spending most of their day outdoors is a common practice? In this study, I question the deterministic models for environmental learning and examine what it means for children to be in nature. To do so I made an empirical study focusing on the children’s own experiences by asking the questions: What is going on out there? What does it mean for the children’s experiences when the kindergarten is moving their everyday activities into the nature-landscapes and places? In exploring these questions a critical approach on the educational ideas of this practice is implicated. LÄS MER

5. 19. Year-round production of forest seedlings under LED lamps : Biological and energetic implications of indoor cultivation

   Författare :Marco Hernandez Velasco; Uwe Zimmermann; Anders Mattsson; Frank Fiedler; Johanna Riikonen; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Picea abies; Pinus sylvestris; year-round cultivation; forest seedlings; LED lamps; light quality; light quantity; daily light integral; adaptive lighting control; greenhouse integrated photovoltaics; agrivoltaics; seedling growth performance; short-day treatments; cold hardiness; light shock stress; Engineering Science; Teknisk fysik;

   Sammanfattning : Year-round cultivation of forest seedlings under light emitting diodes (LED) is a technology receiving increased attention from nurseries in the boreal forest regions. In these areas, the climate is characterized by strong seasonal fluctuations, resulting in short vegetation periods with narrow time windows for seedling transplanting and outdoor growth. LÄS MER
