Demagogues of hate or shepherds of peace? Examining the threat construction processes of warlord democrats in Sierra Leone and Liberia
How are threat images framed and constructed by the so-called warlord democrats (WDs)? Societies that have suffered from large-scale civil wars are commonly permeated by inter-group fear and hate. In these contexts, former military or political leaders of armed groups sometimes become involved in post-war politics. These WDs can act as reconciliation spoilers by making securitising moves, i.e. the
The evolution of host-symbiont dependence
Organisms across the tree of life form symbiotic partnerships with microbes for metabolism, protection and resources. While some hosts evolve extreme dependence on their symbionts, others maintain facultative associations. Explaining this variation is fundamental to understanding when symbiosis can lead to new higher-level individuals, such as during the evolution of the eukaryotic cell. Here we p
An education policy paradigm that fails upper secondary school pupils
In this article, we illustrate the creation of the education policy paradigm that constitutes the framework of vocational education and training (VET) programmes, and analyse local school representatives’ perception of VET in upper secondary schools in Sweden. The education policy paradigm, established through three periods of reform during the twentieth century, undervalues VET as being less wort
Quantitative Imaging of Ozone Vapor Using Photofragmentation Laser-Induced Fluorescence (LIF)
In the present work, the spectral properties of gaseous ozone (O3) have been investigated aiming to perform quantitative concentration imaging of ozone by using a single laser pulse at 248 nm from a KrF excimer laser. The O3 molecule is first photodissociated by the laser pulse into two fragments, O and O2. Then the same laser pulse electronically excites the O2 fragment, which is vibrationally ho
Astrocytic expression of GSTA4 is associated to dopaminergic neuroprotection in a rat 6-OHDA model of Parkinson’s disease
Idiopathic Parkinson’s disease (PD) is a complex disease caused by multiple, mainly unknown, genetic and environmental factors. The Ventral root avulsion 1 (Vra1) locus on rat chromosome 8 includes the Glutathione S-transferase alpha 4 (Gsta4) gene and has been identified in crosses between Dark Agouti (DA) and Piebald Virol Glaxo (PVG) rat strains as being associated to neurodegeneration after ne
Epitope mapping of a new anti-Tn antibody detecting gastric cancer cells
Here, we introduce a novel scFv antibody, G2-D11, specific for two adjacent Tn-antigens (GalNAc- Ser/Thr) binding equally to three dimeric forms of the epitope, Ser-Thr, Thr-Thr and Thr-Ser. Compared to other anti-Tn reagents, the binding of G2-D11 is minimally influenced by the peptide structure, which indicates a high degree of carbohydrate epitope dominance and a low influence from the protein
Observing femtosecond fragmentation using ultrafast X-ray-induced auger spectra
Molecules often fragment after photoionization in the gas phase. Usually, this process can only be investigated spectroscopically as long as there exists electron correlation between the photofragments. Important parameters, like their kinetic energy after separation, cannot be investigated. We are reporting on a femtosecond time-resolved Auger electron spectroscopy study concerning the photofragm
Samarbete och vision – en fallstudie över en musikhögskolas relation till amatörorkesterverksamhet
Detta paper är en del i en fallstudie som undersöker vad musikhögskolestudenter lär sig genom att delta i amatörorkesterverksamhet och vad det tillför utbildningen. Studien består av åtta intervjuer, fyra med utbildningsledning för en musikhögskola och fyra med dirigenter för amatörorkestrar där musikhögskolestudenter deltar. Här presenteras endast den del som rör relationen mellan musikhögskolan

A newly discovered autographed Franz Liszt transcription for the harp
It is well known that Franz Liszt was fond of the harp as an instrument, and his use of the harp in the orchestra is innovative. He also befriended and worked with prominent harpists of his time, such as Elias Parish-Alvars, Wilhelm Posse, Jeanne Pohl and Rosalie Spohr. The transcriptions he once made for harp are now lost. However, a recent finding in a collec- tion in a Swedish museum, Murberget

rt-muse : measuring real-time characteristics of execution platforms
Operating systems code is often developed according to principles like simplicity, low overhead, and low memory footprint. Schedulers are no exceptions. A scheduler is usually developed with flexibility in mind, and this restricts the ability to provide real-time guarantees. Moreover, even when schedulers can provide real-time guarantees, it is unlikely that these guarantees are properly quantifie
Spatial variability of CO2 uptake in polygonal tundra : Assessing low-frequency disturbances in eddy covariance flux estimates
The large spatial variability in Arctic tundra complicates the representative assessment of CO2 budgets. Accurate measurements of these heterogeneous landscapes are, however, essential to understanding their vulnerability to climate change. We surveyed a polygonal tundra lowland on Svalbard with an unmanned aerial vehicle (UAV) that mapped ice-wedge morphology to complement eddy covariance (EC) fl
Evidence for Anisotropic Electronic Coupling of Charge Transfer States in Weakly Interacting Organic Semiconductor Mixtures
We present a comprehensive investigation of the charge-transfer (CT) effect in weakly interacting organic semiconductor mixtures. The donor-acceptor pair diindenoperylene (DIP) and N,N′-bis(2-ethylhexyl)-1,7-dicyanoperylene-3,4/9,10-bis(dicarboxyimide) (PDIR-CN2) has been chosen as a model system. A wide range of experimental methods was used in order to characterize the structural, optical, elect
ENSO influence on rainy season precipitation over the Yangtze River Basin
The paper explores the impact of El Niño-Southern Oscillation (ENSO) on rainy season precipitation properties over the Yangtze River Basin. The multi-scale moving t-test was used to determine the onset and withdrawal of the rainy season. Results showed the following: (1) Onset and withdrawal of the averaged rainy season over the Yangtze River Basin showed a similar distribution and both progressed
Impedance Matching for VSC-HVDC and Energy Storage Damping Controllers
The small-disturbance electro-mechanical dynamics of a power system can be translated to an equivalent circuit model with inductances and capacitances. Damping control of active power in proportion to local frequency as with a VSC-HVDC link or an energy storage then corresponds to introducing a resistor in the circuit model. This letter shows that impedance matching can be used to select resistor
Minimization of Antenna Quality Factor
Optimal currents on arbitrarily shaped radiators with respect to the minimum quality factor are found using a simple and efficient procedure. The solution starts with a reformulation of the problem of minimizing quality factor Q as an alternative, so-called dual, problem. Taking advantage of modal decomposition and group theory, it is shown that the dual problem can easily be solved and always res
