Information activities and appropriation in teacher trainees’ digital, group-based learning

Introduction: This paper reports results from an ethnographic study of teacher trainees’ information activities in digital, group-based learning and their relation to the interplay between use and appropriation of digital tools and the learning environment. Method. The participants in the present study are 249 pre-school teacher trainees in Sweden. Three key informants and their teams were followe

Considering fungal:bacterial dominance in soils - Methods, controls, and ecosystem implications

An expectation in soil ecology is that a microbial communities' fungal:bacterial dominance indicates both its response to environmental change and its impact on ecosystem function. We review a selection of the increasing body of literature on this subject and assess the relevance of its expectations by examining the methods used to determine, the impact of environmental factors on, and the expecte

Dual-VT 4kb Sub-VT Memories with <1 pW/bit Leakage in 65 nm CMOS

Two standard-cell based memories (SCMs) for op- eration in the subthreshold (sub-VT) region are presented. The SCMs accomplish the task of robust sub-VT storage and fill the gap of missing sub-VT memory compilers. The storage elements (latches) of these SCMs are custom-designed cells using a dual- VT approach to balance timing. Additionally, two read-logic styles are presented: 1) a segmented 3-st

Large-scale monitoring of waders on their boreal and arctic breeding grounds in northern Europe

Large-scale and population-wide monitoring of waders on their boreal and arctic breeding grounds has hitherto been lacking, mainly because logistics are truly challenging in regions with few ornithologists, vast areas and few roads. In Norway, Sweden and Finland (here 'Fennoscandia') there are now national monitoring schemes in place, aimed at tracking all bird species, which allows trends to be e

Remotely-sensed, nocturnal, dew point correlates with malaria transmission in Southern Province, Zambia: a time-series study

Background: Plasmodium falciparum transmission has decreased significantly in Zambia in the last decade. The malaria transmission is influenced by environmental variables. Incorporation of environmental variables in models of malaria transmission likely improves model fit and predicts probable trends in malaria disease. This work is based on the hypothesis that remotely-sensed environmental factor

Baltic-Finns and Scandinavians : Comparative-Historical Linguistics and the Early History of the Nordic Region

The study investigates how the early nineteenth century invention of comparative-historical linguistics affected European ethnohistoric thought, and how this process altered ethnohistorical research on the early, pre-Christian history of the Nordic region. The case study of the Nordic region (Denmark, Iceland, Norway, Sweden, Finland and Estonia) includes the discipline histories of Finno-Ugric st

Rural avenues as dispersal corridors for the vulnerable saproxylic beetle Elater ferrugineus in a fragmented agricultural landscape

Understanding factors that limit gene flow through the landscape is crucial for conservation of organisms living in fragmented habitats. We analysed patterns of gene flow in Elater ferrugineus, an endangered click beetle living in old-growth, hollow trees in a network of rural avenues surrounded by inhospitable arable land. Using amplified fragment length polymorphism (AFLP) data, we aimed to eval

Effect of Hydrophobicity on the Interaction between Antimicrobial Peptides and Poly(acrylic acid) Microgels

The influence of peptide hydrophobicity on the interaction between antimicrobial peptides and poly(acrylic, acid) microgels wits studied by end-tagging the kininogen-derived antimicrobial peptide GKHKNKGKKNGKHNGWK (GKH17) and its truncated variant KNKGKKNGKH (KNK10) with oligotryptophan groups of different lengths. Microgel deswelling and reswelling in response to peptide binding and release was s

Median and Ulnar Nerve Injuries in Children and Adolescents- Long-term outcome and Cerebral reorganisation

A peripheral nerve injury may lead to serious disability and influence the individual´s quality of life. It is considered that children can regain better sensory and motor function after a peripheral nerve injury, but the exact mechanism behind such superior recovery is not known. The aim of the thesis was to study the long-term clinical outcome after a peripheral nerve injury in patients injured

Cobalamins uncovered by modern electronic structure calculations

This review describes how computational methods have contributed to the held of cobalamin chemistry since the start of the new millennium. Cobalamins are cobalt-dependent cofactors that are used for alkyl transfer and radical initiation by several classes of enzymes. Since the entry of modern electronic-structure calculations, in particular density functional methods, the understanding of the mole

Reduced chlorophyll biosynthesis in heterozygous barley magnesium chelatase mutants

Chlorophyll biosynthesis is initiated by magnesium chelatase, an enzyme composed of three proteins, which catalyzes the insertion of Mg2+ into protoporphyrin IX to produce Mg-protoporphyrin IX. In barley (Hordeum vulgare L.) the three proteins are encoded by Xantha-f, Xantha-g and Xantha-h. Two of the gene products, XanH and XanG, belong to the structurally conserved family of AAA+ proteins (ATPas

Gendering agency in transitional justice

Mainstream transitional justice and peacebuilding practices tend to re-entrench gendered hierarchies by ignoring women or circumscribing their presence to passive victims in need of protection. As a consequence we have limited knowledge about the multifaceted ways women do justice and build peace. To address this lacuna we conceptualize and unpack the meaning of gendered agency, by identifying its

Climate Change, Adaptation, and Formal Education: the Role of Schooling for Increasing Societies' Adaptive Capacities in El Salvador and Brazil

With a worldwide increase in disasters, the effects of climate change are already being felt, and it is the urban poor in developing countries who are most at risk. There is an urgent need to better understand the factors that determine people's capacity to cope with and adapt to adverse climate conditions. This paper examines the influence of formal education in determining the adaptive capacity

Response of Passerine Birds to an Irruption of a Pine Processionary Moth Thaumetopoea Pityocampa Population with a Shifted Phenology

Response of passerine birds to an irruption of a pine processionary moth Thaumetopoea pityocampa population with a shifted phenology The main purpose of the present work was to investigate if the passerine community was able to respond to it localized irruption of a temporally shifted population of the pine processionary moth Thaumetopoea pityocampa, the larval development of which takes place dur

Relations at order p(6) in chiral perturbation theory

We report on a search of relations valid at order p(6) in Chiral Perturbation Theory. We have found relations between pi, pi K scattering, K-l4 decays, masses and decay constants and scalar and vector formfactors. In this paper we give the relations and a first numerical check of them.
