3. 7. Movement towards socioecological change: The case of Ecosomatics

   Kandidat-uppsats, Göteborgs universitet/Institutionen för globala studier

   Författare :Wilma Lagerman; [2024-03-19]
   Nyckelord :;

   Sammanfattning : Several scholars both within and outside the field of human ecology argue that the perceptual human-nature divide contributes profoundly to patterns of unsustainability and weak sustainability visible in the world today. Deliberately engaging in conscious bodily-felt contact with the natural environment is suggested to uncover appropriate, embodied angles to approaching ecology and the environmental crisis. LÄS MER

4. 8. The forgotten sand bee. A follow up on the status of the golden sand bee Andrena marginata in municipality of Mark, a decade later

   Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

   Författare :Monika Böttcher; [2024-03-19]
   Nyckelord :Golden sand bee; Andrena marginata; Devil´s bit scabious; Succisa pratensis; Oligolectic bees; Inventory; Meadow land; Conservation;

   Sammanfattning : Over a decade ago, a conservation project aimed at preserving the endangered golden sand bee (Andrena marginata) populations in the Storån valley of the municipality of Marks was initiated. The species, red-listed in Sweden as well as in many other European country, specializes in pollen from Devil's bit. LÄS MER

5. 9. Oligolectic bee species. An understudied group in Global Change impacts?

   Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

   Författare :Monika Böttcher; [2024-03-19]
   Nyckelord :Solitary bee; global change; oligolecty; red list; taxonomy;

   Sammanfattning : Global change is considered the primary cause of the decline in bees worldwide, posing a significant threat to crucial pollination services they provide, carrying negative economic and ecological implications. Despite the extensive research conducted on the responses of bee communities to anthropogenic impacts, the focus has predominantly been on commercially interesting bees. LÄS MER

7. 10. Feature Selection for Microarray Data via Stochastic Approximation

   Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

   Författare :Erik Rosvall; [2024-03-18]
   Nyckelord :feature selection; feature ranking; microarray data; stochastic approximation; Barzilai and Borwein method; Machine Learning; AI;

   Sammanfattning : This thesis explores the challenge of feature selection (FS) in machine learning, which involves reducing the dimensionality of data. The selection of a relevant subset of features from a larger pool has demonstrated its effectiveness in enhancing the performance of various machine learning algorithms. LÄS MER
