Uppsatsen handlar om en analys av debatten kring den svenska militära insatsen i Afghanistan året 2010 då tre svenska soldater respektive en afghansk tolk stupade samt flera andra svenska soldater skadades. Till följd av detta, uppstod debatten på Aftonbladet (AB) mellan Jan Guillou och Jan Eliasson, på Svenska Dagbladet (SvD) uppstod debatten mellan Maria-Pia Boëthius och Carl Bildt och på Dagens
AbstractThe need to minimise wear of hardmetal cutting tool materials requires an understanding of, and in turn accurate measurement of, both the external changes in dimensions and the internal microstructural changes which cause plastic deformation underneath the tool coating.This paper summarises development of methods to quantify the dimensional changes of the complex 3D tip shape of a tool and
PURPOSE: To elucidate the pathophysiology of the carotid sinus reflex in a large cohort of patients with suspected reflex syncope.METHOD: We reviewed an electronic database of patients with suspected reflex syncope who underwent carotid sinus massage. The diagnostic protocol included both right and left massage, in supine and upright positions, followed by tilt testing.RESULTS: The cohort included
We investigated fungal growth and community composition in buried meshbags, amended with apatite, biotite or hornblende, in Norway spruce (Picea abies) forests of varying nutrient status. Norway spruce needles and soil collected from forests overlying serpentinite had low levels of potassium and phosphorus, those from granite had low levels of magnesium, whereas those from amphibolite had comparab
Plant species effects on microbial communities are attributed to changes in microbial community composition and biomass, and may depend on plant species specific differences in the quality of resources (carbon) inputs. We examined the idea that plant-soil feedbacks can be explained by a chance effect, which is the probability of a highly productive or keystone plant species is present in the commu

Neonicotinoid insecticides applied to flowering crops can have negative impacts on bees, with implications for crop pollination. To assess if exposure to the neonicotinoid clothianidin via a treated crop (rapeseed) affected bee behaviour, pollination performance (to strawberry), and bee reproduction, we provided each of 12 outdoor cages with rapeseed (autumn-sown plants complemented with a few spr
Are there indications for the neoliberal hegemony in economy and society to come to an end? Are people already imagining a future within environmental limits and beyond the growth imperative? Theoretically, building upon Marx and Bourdieu, we reconstruct the ideological impact that capitalism, in general, and neoliberalism, in particular, has on the ways we think, feel and make sense of our enviro
Dig a teaspoon into your nearest clump of soil, and what you’ll emerge with will contain more microorganisms than there are people on Earth. We know this from lab studies that analyse samples of earth scooped from the microbial wild to determine which forms of microscopic life exist in the world beneath our feet.
Filamentous fungi play a key role in the terrestrial carbon cycle as they are the primary decomposers of lignocellulose in soil organic matter (SOM). Fungi secrete a wide range of oxidative and hydrolytic enzymes, and generate radicals through extracellular secondary metabolites to decompose SOM. To study fungal decomposition of SOM, the activities of isolated enzymes are typically studied as prox
Agricultural intensification and extreme weather events can represent considerable stress to soil microorganisms and their functions by influencing the key players behind the degradation of soil organic matter. A better understanding of the diversity and abundance of microbial functional genes that predict the functional potential of soils, can link the microbial communities to their key ecosystem
The nitrogen (N) cycle is a familiar concept. As is the much simplified, often diagrammatic, representation commonly used to illustrate the scale, importance and interconnectedness of this global cycle that links air, water, rocks and living beings. However, in this representation, humans are often presented as a seemingly minor entity or not explicitly shown at all. This can obscure the idea that
Anthropogenic nitrogen (N) deposition and fertilization in boreal forests frequently reduces decomposition and soil respiration and enhances C storage in the topsoil. This enhancement of the C sink can be as strong as the aboveground biomass response to N additions and has implications for the global C cycle, but the mechanisms remain elusive. We hypothesized that this effect would be associated w
Landscape-scale land use is important in driving species communities and interactions. However, despite increasing concerns regarding the ecological consequences of insect declines, our understanding of how the relative proportions of different land cover types influence insect herbivory in species-rich semi-natural habitats remains limited. This study assessed leaf, stem, and flower herbivory acr
Plant functional traits are fundamental to ecosystem dynamics and Earth system processes, but their global characterization is limited by available field surveys and trait measurements. Recent expansions in biodiversity data aggregation—including vegetation surveys, citizen science observations, and trait measurements—offer new opportunities to overcome these constraints. Here we demonstrate that
Groundwater-dependent vegetation (GDV) plays a vital role in maintaining biodiversity and ecosystem services in the Mediterranean biome but is increasingly threatened by climate and land use change. Large-scale GDV mapping in arid regions is critical for effective conservation and water resource management but remains challenging due to limited ground-truth data and the lack of high-resolution rem
The search for predictors of plant diversity has challenged scientists for decades. Here we identify intense photosynthetically active radiation (PAR) as a major factor constraining plant species richness in global grasslands. We show that the strength of the negative relationship between species richness and PAR increases with increasing elevation and that species richness is more strongly correl
