    Author : Andreea Valentina Moraru; [2021]
    Keywords : Neighbourhood effects; Education; Malmö; fsQCA; privatisation of education; Qualitative Comparative Analysis; Social Sciences;

    Abstract : How do neighbourhoods affect life chances? This is a question that researchers have asked in different forms as early as the 50’s –and there is no shortage of papers exploring neighbourhood effects: how where we live affects our well-being or our participation in the labour market, our life expectancy or, in general, our life outcomes. Yet, there is less consensus than one would expect from a field that has been this active: mechanisms are not clearly defined, methodologies are often one-sided, theoretical concepts are outdated and sometimes harmful for communities and contextuality of most kinds is surprisingly rare.

  3. 7. Evolutionary Theories of Menopause

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Fanny Hägg; [2020]
    Keywords : Menopause; Post-reproduction; The grandmother hypothesis; The reproductive conflict hypothesis; Inclusive fitness; Kin selection; Odontoceti; Orcinus orca;

    Abstract : Menopause, the cessation of female reproduction well before death, is a puzzling phenomenon, because evolutionary theory suggests there should be no selection for survival when reproduction has ended.

  6. 10. Gynnas talgoxens häckningsframgång av gallring i barrskogen? : en experimentell studie om anpassad skogsgallring

    University essay from SLU/Dept. of Ecology

    Author : Angelia Ellvin; [2020]
    Keywords : talgoxe; häckningsframgång; boreal skog; gallring; undervegetation;

    Abstract : Skogsbruket orsakar strukturella förändringar som hotar biologisk mångfald världen över, men industrin är samtidigt nödvändig för samhället. Speciellt undervegetationen försvinner ofta vid låggallring (CT), som är den dominerande gallringsmetoden i bl.a. Skandinavien, Baltikum och Ryssland. READ MORE
