Threshold Effects of Public Spending on Sectoral Growth in Sub-Saharan Africa

Prudence M. Kotounnou, François Joseph Cabral

World Scientific News > 2023 > 176 > 145-161

This paper analyzes the effects of public expenditure thresholds on the sectoral contribution to GDP growth with particular emphasis on the three macro-sectors of the economy (agriculture, industries and services). It appears that when public expenditure in the "agriculture" sector is less than 1.22% of national GDP, it has an insignificant and negative effect on the contribution of this...

Giulio Fanti

World Scientific News > 2023 > 176 > 104-120

Although the double body image of the Holy Shroud (HS) is still today inexplicable and even less reproducible, various hypotheses have been formulated which attempt to explain at least in part what is observed on the most important Relic of Christianity. Many of these hypotheses refer to an intense energy emitted by the corpse that often comes out of traditional science and calls into question the...

Christian Ebere Enyoh, Franklyn Okechukwu Ohiagu, Blessing Margarette Obidike, Beniah Obinna Isiuku, more

World Scientific News > 2023 > 176 > 76-103

Phytoremediation, which is the use of water-loving plants, proposed over 300 years ago has gained explicit acceptance as a more prolific approach towards the removal and uptake of organic and heavy metals pollutants. Metals gain access into water bodies through natural geochemical weathering of rocks and various indiscriminate human activities which includes waste generated from mining industries,...
