The genus Draba L. is a conspicuous element of the arctic flora, comprising about 350 species worldwide which mostly are arctic-alpine polyploids. Previously, it has mainly been Draba incana L., D. norvegica Gunn., D. nivalis Liljebl., D. alpina L., D. fladnizensis Wulf., D. daurica DC., D. lactea and D. cinerea Adams that have been considered as belonging to the Icelandic flora. In this paper we
In Swedish historical archaeology, studies of towns have diverged from definition to deconstruction. In landscape studies the existence of occasional similar expressions of power in rural contexts as in towns is stressed. Another observation is that towns can display vague forms of urbanity, with lack of dense settlement and varied economy, as well as showing agrarian affiliations. A focus on sing
The aim of this article is to explore how ‘children's rights’ and ‘gender equality’ are articulated in parenting support policies in Sweden, and how these policies are enacted in practice with respect to the two perspectives mentioned. The analysis builds on key policy documents and interviews with civil servants working on parenting support on local, regional and national levels. The results show
Recent studies find that higher degrees of democracy are related to higher levels of bureaucratic quality. However, they only offer limited explanations for this pattern based on a unidimensional understanding of democracy. We argue that future uncertainties as perceived by the incumbent, the opposition, and voters are important for why bureaucratic reform takes place. Therefore, we expect no unif
This study considers evolutionary games with non-uniformly random matching when interaction occurs in groups of n ≥ 2 individuals using pure strategies from a finite strategy set. In such models, groups with different compositions of individuals generally co-exist and the reproductive success (fitness) of a specific strategy varies with the frequencies of different group types. These frequencies c
In this paper we describe present work on multimodal prosody by means of simultaneous recordings of articulation and head movements. Earlier work has explored patterning, usage and machine-learning based detection of focal pitch accents, head beats and eyebrow beats through audiovisual recordings. Kinematic data obtained through articulography allows for more comparable and accurate measurements, In this paper we describe present work on multimodal prosody by means of simultaneous recordings of articulation and head movements.

MIMO is an undisputed breakthrough in advanced wireless technology, as it offers potentially linear increase in information-theoretic capacity with the number of antennas. However, the implementation of MIMO in compact terminals is a relatively uncharted topic, due to challenging problems with high antenna correlation and mismatch loss, both of which greatly reduces the expected MIMO gains. In thi
In the sporadic permafrost zone of North America, thaw‐induced boreal forest loss is leading to permafrost‐free wetland expansion. These land cover changes alter landscape‐scale surface properties with potentially large, however, still unknown impacts on regional climates. In this study, we combine nested eddy covariance flux tower measurements with satellite remote sensing to characterize the imp
Global carbon balances are increasingly affected by large fluctuations in productivity occurring throughout semiarid regions. Recent analyses found a large C uptake anomaly in 2011 in arid and semiarid regions of the southern hemisphere. Consequently, we compared C and water fluxes of two distinct woody ecosystems (a Mulga (Acacia) woodland and a Corymbia savanna) between August 2012 and August 20
This study presents a comparison and integration of three methods commonly used to estimate the amount of forest ecosystem carbon (C) available for storage. In particular, we examine the representation of living above- and below-ground biomass change (net accumulation) using plot-level biometry and repeat airborne laser scanning (ALS) of three dimensional forest plot structure. These are compared
Fluxes of methane, CH4, were measured with the eddy covariance (EC) method at a small boreal lake in Sweden. The mean CH4 flux during the growing season of 2013 was 20.1 nmol m−2 s−1 and the median flux was 16 nmol m−2 s−1 (corresponding to 1.7 mmol m−2 d−1 and 1.4 mmol m−2 d−1). Monthly mean values of CH4 flux measured with the EC method were compared with fluxes measured with floating chambers (
Investigation of the relationship between tree-ring stable carbon isotope composition (δ13C) and environmental variables at the intra-seasonal scale can inform on the understanding of the environmental forcing affecting trees during the active period of radial growth. Recent progress in the measurement techniques for assessing the δ13C signature of tree rings at high spatial resolution provides an
Variations in laser properties and data acquisition times introduced inconsistencies in Geoscience Laser Altimeter System (GLAS) data. The effect of data inconsistencies, on two GLAS height retrieval methods, from three study sites, are investigated and validated against airborne laser scanning (ALS) percentile heights, from three data sources: all/first return point clouds, and raster canopy heig
