1. 1. Riparian plant biodiversity and community composition of ditches and straightened streams : identifying key environmental drivers in a boreal forest setting

   Master-uppsats, SLU/Dept. of Forest Ecology and Management

   Författare :Rasmus Staaf; [2024]
   Nyckelord :artificial waterways; riparian zone; novel ecosystems; ; forestry; ditch network maintenance; species richness; hill-diversity; drainage ditches; coarse woody debris; ditch cleaning; ecology;

   Sammanfattning : Modified ecosystems are typically seen as degraded and having no ecological value. In many cases, the modification of the ecosystem was done more than 100 years ago and may have had time to recover and become a refugia for species that were once more common in the landscape.

3. 2. Svenska företags gömda bildspråk : En studie om representation och gestaltning mellan könen på svenska företags ”om oss”-sidor

   Kandidat-uppsats, Linnéuniversitetet/Institutionen för medier och journalistik (MJ)

   Författare :Linnéa Mellbin; Engström Annie; [2024]
   Nyckelord :Framing theory; representation theory; gender theory; gender stereotypes; Roland Barthes mythologies; mixed methods; content analysis; webpages; Swedish corporations;

   Sammanfattning : Women are generally underrepresented in media and have historically been degraded to stereotypical roles in media content. Sweden is a country that has actively worked with equality between the genders since the 1970s. The country's progress in equality piqued the scientists interest in the extent of gender stereotypes in Swedish media content. LÄS MER

4. 3. Dynamic Risk Management in Air Traffic Management System Failures

   Magister-uppsats, Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

   Författare :Nick Lowth; [2024]
   Nyckelord :Air Traffic Control; Uncertainty; Risk Management; Air Traffic Management; Resilience; Emergence; Trade-offs; FLMU06; Social Sciences;

   Sammanfattning : Context This research looks at managing uncertainty and recovery processes following failure of a sociotechnical system. The provision of Air Traffic Services (ATS) is an essential service that must continue to function supporting at a minimum; medical flights, search and rescue operations, humanitarian aid, State and military flights (as demonstrated during the recent global pandemic).

5. 4. Biokinetic Characterization of Methane Oxidizing Microbiomes Co-metabolizing Trace Organic Chemicals

   Master-uppsats, Lunds universitet/Teknisk mikrobiologi

   Författare :Hugo Möller; [2024]
   Nyckelord :Methanotrophs; organic micropollutants; co-metabolism; biodegradation; applied microbiology; Earth and Environmental Sciences;

   Sammanfattning : The presence of organic micropollutants (OMPs) in wastewater effluents is concerning, as they pose a threat to human and aquatic health. Biodegradation via methane-oxidizing bacteria (MOB) is an attractive option, as the method is cheap and effective. MOB can co-metabolize a variety of substrates, there among organic micropollutants.

7. 5. Regenerativt lantbruk: En kvalitativ studie om möjligheter och utmaningar med att driva ett lantbruk som regenererar jord och ekosystem

   Kandidat-uppsats, Göteborgs universitet/Institutionen för globala studier

   Författare :Julia Mattzon; Julia Mattzon; [2023-10-26]
   Nyckelord :Regenerative agriculture; regeneration; agricultural systems; sustainable development; planetary boundaries; climate crisis; food security; holistic management; social movement; relationship with nature; social well-being;

   Sammanfattning : Regenerative agriculture has recently received worldwide attention from researchers, policy makers, journalists, and farmers for its potential to regenerate degraded soil and ecosystems. It has been presented as a solution to address the challenges that the agricultural system faces today: food insecurity, negative environmental impact, economic chocks, and climate crises. LÄS MER
