4. 38. Treåringar, kameror och förskola – en serie diffraktiva rörelser

   Författare :Lena O Magnusson; Claes Eriksson; Tarja Karlsson Häikiö; Hillevi Lenz Taguchi; Högskolan i Gävle; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; digital camera; young children; pre-school; aesthetics; gaze; photography; ethics; agential realism; intra-action; diffraction; Innovative Learning; Innovativt lärande; digital camera; young children; pre-school; aesthetics; gaze; photography; ethics; agential realism; intra-action; diffraction;

   Sammanfattning : The aim of this thesis is to examine what happens when three-year-olds are given access to digital cameras, and what shape and form children’s photographic capacity takes within the framework of everyday pre-school activities. The notion that young children in pre-school rarely get to use cameras themselves, and that they take part in photographs produced by pre-school educators as part of an ongoing documenting practice rooted in the curriculum is the point of departure.

7. 40. Gudinnefeminister : Monica Sjöös och Starhawks berättande - subjektskonstruktion, idéinnehåll och feministiska affiniteter

   Författare :Magdalena Raivio; Ulf Mellström; Claudia Lindén; Karlstads universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Goddess feminism; Monica Sjöö; Starhawk; eco feminism; religion; new religious movements; religious studies; gender studies; feminist theory; feminist historiography; discourse analysis; narrativity; diffraction; Religious Studies and Theology; Religionsvetenskap;

   Sammanfattning : This thesis examines the discursive position of 'goddess feminism', in relation to some of the difference- and eco feminist positions from the1960s and until today. In focus are the texts of the two goddess feminists, Monica Sjöö and Starhawk. The thesis contributes to a historiographical (re)situating of their political and religious narratives. LÄS MER
