This paper makes two contributions to the literature. First, by employing a macrolevel institutional dataset on benefit levels for social assistance (SA) and minimum income protection (MIP) in 22 European countries in the period 1990–2013, I show that the adequacy of income support for low-income inactive individuals in European welfare states has been steadily decreasing since 1994. Second, th...

We make several contributions that quantify the real-time hash rate and therefore the consensus of a blockchain. We show that by using only the hash value of blocks, we can estimate and measure the hash rate of all miners or individual miners, with quantifiable accuracy. We apply our techniques to the Ethereum and Bitcoin blockchains; our solution applies to any proof-of-work-based blockchain t...

A frequently proposed method of reducing unsolicited bulk email (“spam”) is for senders to pay for each email they send. Proof-ofwork schemes avoid charging real money by requiring senders to demonstrate that they have expended processing time in solving a cryptographic puzzle. We consider how difficult that puzzle should be so as to be effective in preventing spam. We analyse this both from an...

Ammonium nitrate is a semivolatile aerosol component under typical ambient conditions and thus difficult to measure. In the field, the aersosol scattering coefficient is usually measured with a nephelometer by heating the ambient aerosol to a low reference relative humidity (∼40%) in order to measure a light scattering coefficient that is intrinsic to an aerosol rather than dependent on atmosph...

this study aims at testing the degree of stability for beta coefficient across time, depending on the information available from tehran bourse. where beta coefficient was calculated using the market model developed by sharp on 1963, which applies by performing a simple linear regression between the company’s and the market returns, where beta coefficient is the slope of this regression. in this...

OBJECTIVES To examine the demographic and psychosocial factors associated with increased fruit and vegetable (FV) consumption among smokers residing in public housing. DESIGN Cluster randomized trial of 20 public housing developments (HDs). Ten housing developments were randomly assigned to a FV intervention and 10 to a smoking cessation intervention. PRIMARY OUTCOME Change in daily FV inta...

Soret coefficients of the ternary system of poly(ethylene oxide) in mixed water/ethanol solvent were measured over a wide solvent composition range by means of thermal diffusion forced Rayleigh scattering. The Soret coefficient S(T) of the polymer was found to change sign as the water content of the solvent increases with the sign change taking place at a water mass fraction of 0.83 at a temper...

We consider a multidimensional Itô process Y = (Yt)t∈[0,T ] with some unknown drift coefficient process bt and volatility coefficient σ(Xt, θ) with covariate process X = (Xt)t∈[0,T ], the function σ(x, θ) being known up to θ ∈ Θ. For this model we consider a change point problem for the parameter θ in the volatility component. The change is supposed to occur at some point t∗ ∈ (0, T ). Given di...

introduction: falling is a common problem after stroke that occurs following the physical and psychological problems. psychological factors such as reduce of self-efficacy in maintain balance could have an equal or even greater contribution than physical problems in falling. therefore, having a suitable tool with acceptable repeatability seems to be necessary for evaluation of individual confid...
