Making Direct Democracy Work : An economic perspective on the graphe paranomon in ancient Athens

The specific way the Athenians set up their democracy presents both theoretical and empirical challenges. Decisions were taken by majority vote in the Assembly. To keep politicians in line, the Athenians first used ostracism, which however was replaced by the graphe paranomon around 415 BCE. The latter provided that anybody who had made a proposal in the Assembly could be accused of having made an

Subunit II of Bacillus subtilis cytochrome c oxidase is a lipoprotein

The sequence of the N-terminal end of the deduced ctaC gene product of Bacillus species has the features of a bacterial lipoprotein. CtaC is the subunit II of cytochrome caa3, which is a cytochrome c oxidase. Using Bacillus subtilis mutants blocked in lipoprotein synthesis, we show that CtaC is a lipoprotein and that synthesis of the membrane-bound protein and covalent binding of heme to the cytoc

Pro-poor agricultural growth – Inclusion or differentiation? Village level perspectives from Zambia

Over the past decade pro-poor agricultural growth strategies intended to raise smallholder productivity and increase commercialization among smallholders have been put forth as the key method for addressing poverty in rural Africa. By contrast perspectives that challenge this model question the market optimism and presumptions of higher smallholder efficiency that underpin the pro-poor agricultura

Co-designing wearable technology together with visually impaired children

This paper presents the process and results of a set of studies within the ABBI EU project, with the general aim to co-design wearable technology (an audio bracelet) together with visually impaired children, starting at a young age. The authors discuss user preferences related to sounds and tactile materials and present the results of a focus group with very young visually-impaired children under

Implementation and validation of an environmental feedback pool fire model based on oxygen depletion and radiative feedback in FDS

This paper has been aimed at implementing and validating a simplified environmental feedback fire model in FDS as a complement to more advanced pyrolysis models. The two main means of environmental feedback have been identified as the oxygen concentration close to the fuel base and the radiative feedback from the surrounding obstructions and smoke layer. The oxygen concentration at the fuel base h

Long-term effective population size dynamics of an intensively monitored vertebrate population

Long-term genetic data from intensively monitored natural populations are important for understanding how effective population sizes (N e) can vary over time. We therefore genotyped 1622 common buzzard (Buteo buteo) chicks sampled over 12 consecutive years (2002-2013 inclusive) at 15 microsatellite loci. This data set allowed us to both compare single-sample with temporal approaches and explore te

Power Market Structure and Renewable Energy Deployment Experiences From the MENA Region

In almost all countries in the Middle East and North Africa (MENA) region, power sectors are characterized by a high degree of vertical integration and state control. However, several countries have undertaken reforms in order to open up the power market for private sector involvement particularly in relation to renewable energy (RE) sourced electricity generation. The majority of the MENA countri

New Methods for Synthesis of Platinum(II) Dimethyl Sulfide Complexes

Different methods for the synthesis of anionic dimethyl sulfide platinum complexes of the type Q[PtCl3(Me2S)] (Q = triphenylbenzylphosphonium, Ph3PBzl, or tetrabutylammonium, BU4N) and [Pt(mu-Cl)Cl(Me2S)]2 are reported. The compounds Q[PtCl3(Me2S)] were prepared by interaction of [PtCl4]2- with an excess of Me2S in non-aqueous media, reduction of [PtCl5(Me2S)]- with hydrazine sulfate, bridge-split

Growth pattern in Ethiopian infants - the impact of exposure to maternal HIV infection in relation to socio-economic factors

Background: Infants exposed to maternal HIV infection who remain HIV-uninfected (HIV-exposed/uninfected; HIV-EU) may be at increased risk of growth retardation, which could be due both to directly HIV-related effects and to socio-economic factors overrepresented among HIV-positive women. Objective: To investigate growth development at 9-12 months of age in HIV-EU infants participating in preventio

Habitat saturation promotes delayed dispersal in a social reptile

When and where offspring disperse has important implications for the evolutionary emergence and maintenance of group living. In noncooperative breeders, direct benefits of delayed dispersal are relatively limited, suggesting that decisions regarding whether or not to remain in the parental territory are largely driven by the availability of suitable habitat in which to settle. Although there is am

Synthesis and characterization of chiral phosphirane derivatives of [(μ-H)4Ru4(CO)12] and their application in the hydrogenation of an α,β-unsaturated carboxylic acid

Ruthenium clusters containing the chiral binaphthyl-derived mono-phosphiranes [(S)-([1,1'-binaphthalen]-2-yl)phosphirane] (S)-1a, [(R)-(2'-methoxy-1,1'-binaphthyl-2-yl)phosphirane] (R)-1b, and the diphosphirane [2,2'-di(phosphiran-1-yl)-1,1'-binaphthalene] (S)-1c have been synthesized and characterized. The clusters are [(μ-H)4Ru4(CO)11((S)-1a)] (S)-2, [(μ-H)4Ru4(CO)11((R)-1b)] (R)-3, 1,1-[(μ-H)4R

Measurement of the CP-violating phase ϕsand the Bs0meson decay width difference with Bs 0→ J/ψϕ decays in ATLAS

A measurement of the Bs0decay parameters in the Bs0→ J/ψϕ channel using an integrated luminosity of 14.3 fb−1collected by the ATLAS detector from 8 TeV pp collisions at the LHC is presented. The measured parameters include the CP -violating phase ϕs, the decay width Γs and the width difference between the mass eigenstates ΔΓs. The values measured for the physical parameters are statistically combi

Effect of an upstream bulge configuration on film cooling with and without mist injection

To meet the economic requirements of power output, the increased inlet temperature of modern gas turbines is above the melting point of the material. Therefore, high-efficient cooling technology is needed to protect the blades from the hot mainstream. In this study, film cooling was investigated in a simplified channel. A bulge located upstream of the film hole was numerically investigated by anal

Reaching the limits of prognostication in non-small cell lung cancer : an optimized biomarker panel fails to outperform clinical parameters

Numerous protein biomarkers have been analyzed to improve prognostication in non-small cell lung cancer, but have not yet demonstrated sufficient value to be introduced into clinical practice. Here, we aimed to develop and validate a prognostic model for surgically resected non-small cell lung cancer. A biomarker panel was selected based on (1) prognostic association in published literature, (2) p

Elliptic flow of electrons from heavy-flavour hadron decays at mid-rapidity in Pb-Pb collisions at √sNN=2.76 TeV

The elliptic flow of electrons from heavy-flavour hadron decays at mid-rapidity (|y| < 0.7) is measured in Pb-Pb collisions at sNN=2.76 TeV with ALICE at the LHC. The particle azimuthal distribution with respect to the reaction plane can be parametrized with a Fourier expansion, where the second coefficient (v2) represents the elliptic flow. The v2 coefficient of inclusive electrons is measured in
