We study the economic implications of mineral resource activity for non-mining regions at the grid-level across the African continent. We find that capital cities benefit from mineral resource activity anywhere in the country. Leaders’ birth regions also benefit, but only in autocratic regimes. Generic non-mining regions, on the other hand, are worse off. These results suggest that regional redistribution of resource rents in Africa is primarily undertaken to the benefit of capital cities and leaders’ birth regions. In contrast, non-mining regions do not appear to be sufficiently compensated for the negative spillovers they may face due to mining activity elsewhere in the country.

The imagery of the "radiant body" and "luminous garment" occurs frequently in early Christian references to the Edenic state of Adam and its partial reinstatement by Moses, Jesus, and numerous saintly (usually ascetic) figures. This article offers a synthetic presentation of these traditions, sketching out its main articulations, its biblical-exegetical foundations, its points of continuity with the apocalyptic traditions of the Second Temple Era and parallels with the Rabbinic tradition., RIHA Journal, 2019: Special Issue "From Living to Visual Images.

The exact formation scenarios and evolutionary processes that led to the existence of the class of low surface brightness galaxies (LSBs) have not yet been understood completely. Since the environment of LSBs has been studied before only on small scales (below 2 Mpc), a study of the galaxy content in the vicinity of LSB galaxies on larger scales could add a lot to our understanding of the origin of this galaxy class. We used the spectroscopic main galaxy sample of the SDSS DR4 to investigate the environmental galaxy density of LSB galaxies compared to the galaxy density in the vicinity of high surface brightness galaxies (HSBs). The environment studies, divided into two redshift bins, show that both the low mass, and the more massive LSBs possess an environment with a lower galaxy density than HSBs. The differences in the galaxy density between LSBs and HSBs are significant on scales between 2 and 5 Mpc, the scales of groups and filaments. To quantify this, we have introduced for the first time the LSB-HSB Antibias. The obtained LSB-HSB Antibias parameter has a value of 10%-15%. From these results we conclude that LSBs formed in low-density regions of the initial universe and have drifted until now to the outer parts of the filaments and walls of the large-scale structure. Furthermore, our results, together with actual cosmological simulations, show that LSBs are caused by a mixture of nature and nurture., Astronomy & Astrophysics in press
