This paper investigates the relationship between FDI and private investment in Sub-Saharan Africa (SSA), using a sample of 40 countries over 1980-2017. To disentangle short term from long-term dynamics, our empirical analysis is based on Pooled Mean Group (PMG), (MG) Dynamic Full Effects (DFE) models. We find that has little effect run but significant crowding-in effects long-run: one percentag...

In crowding, perception of a target is strongly deteriorated by nearby elements. Crowding is often explained by pooling models predicting that adding flankers increases crowding. In contrast, the centroid hypothesis proposes that adding flankers decreases crowding--"bigger is better." In foveal vision, we have recently shown that adding flankers can increase or decrease crowding depending on wh...

Both cellular environmental factors and chemical modifications critically affect the properties of nucleic acids. However, the structure and stability of DNA containing abasic sites under cell-mimicking molecular crowding conditions remain unclear. Here, we investigated the molecular crowding effects on the structure and stability of the G-quadruplexes including a single abasic site. Structural...

Here, we examined the effects of molecular crowding on the function, structure and stability of nucleases. We found that the hydrolysis of a 29-mer double-stranded DNA by the endonucleases DNase I and S1 nuclease was substantially enhanced by molecular crowding using polyethylene glycol (PEG); however, molecular crowding had little effect on hydrolysis by exo III and exo I exonucleases. Moreove...

The basic idea that rewards, and in particular monetary rewards, may crowd out intrinsic motivation emanates from two quite different branches of literature in the social sciences. In his book The Gift Relationship, Richard Titmuss (1970) argued that paying for blood undermines cherished social values and would therefore reduce or totally eliminate people’s willingness to donate blood. However,...

Proteins are neither purified nor diluted inside the living cell. Thus it is indispensable to take into account various interactions between the protein of interest and other macromolecules for understanding the properties of proteins in physiological conditions. Here we focus on excluded volume interactions which are omnipresent in dense or crowded solutions of proteins and macromolecules or "...
