External Debt and Economic Growth in CFA Countries: Political Institutions Matter?

/in /by

The aim of this paper is to analyse the relation between quality of institutions, external debt and economic growth in the CFA zone. The main contribution of this paper is the endogenous determination of the threshold for quality of institutions beyond and above which external debt affect economic growth differently. The methodology focuses on the estimation of a Panel Smooth Transition Regression (PSTR) model inspired by González et al. (2005). The sample includes 10 countries on the period 1985-2015 on annual frequency. From the empirical analysis, we derive the following conclusions: in countries with lower corruption and a high level of democracy, the level of debt for which the effect of debt on growth becomes negative is higher. This implies that poor institutional quality prevents a country from taking full advantage of its credit opportunities. As a result, only countries with good institutions can fully benefit from the advantages of external debt for economic growth.

Theoretical Consideration of Star Trek’s Space Navigation

/in /by

As is well known, Star Trek is a masterpiece that has been known worldwide since 1966 as a science fiction set in the famous galaxy universe. A starship (Enterprise) arrives in a star system in a short period of time to a star system that is tens, hundreds and thousands of light years away from the Earth. This method of making a starship reach a distant star system is skillfully expressed in the movie using images.

Unfortunately, however, there is no concrete explanation from the physical point of view of the propulsion method of the starship and the principle of warp navigation, that is, the space propulsion theory and the space navigation theory.

This paper is an attempt to explain Star Trek’s space navigation by applying the hyper-space navigation theory to the field propulsion theory that the author has published in international conferences and peer-reviewed journals since 1993 [1].

Since this paper mainly describes the concept of the principle, most of the mathematical expressions are reduced. See the references for theoretical formulas [1, 2, 3, 4, 5, 6].

Current Status and Burden of Malaria in Pregnancy among Women in Some Selected Internally Displaced persons Camps in Maiduguri, Borno State

/in /by

Malaria is a major cause of morbidity and mortality among displaced populations in sub-Saharan Africa, accounting for an estimated 30 million women living in malaria endemic area become pregnant each year. Recent literature indicates that over 140 million people in Nigeria with 97% of the population are at risk from malaria infection. To assess the current status and burden of malaria in pregnancy among women in IDPs camps in Maiduguri, a cross sectional study on the relationship between pregnancy and malaria parasitaemia was conducted among pregnant IDPs women in Maiduguri. Of the 100 pregnant women enrolled in the study and screened for malaria infection, 40 (40%) were examined in Dalori camp, 37 (37%) were examined in Bakasi and 23 (23%) were examined in Aji ganaram camp. The prevalence of malaria infection among pregnant women based on different IDPs camps reveals that, 42(42.0%) out of the 100 pregnant women examined in all the three camps were infected with malaria parasitaemia. In Dalori camp 19(47.5%) out of 40 women examined were infected, while in Aji ganaram camp 16(43.2%) out of 37 women examined were infected, likewise in Bakasi 7(30.4%) out of 23 women examined were infected respectively. There is no statistically significant difference between camps and malaria infection (p˃0.5). Similarly, the prevalence of malaria infection based on age group. Of the sample examined 68 (68%) out of the 100 women examined were infected with malaria parasitaemia, the age group of <15 years had the lowest malaria infection rate with 2 (2.0%) and there was significantly higher prevalence rate of malaria infection  recorded in age group of 15-45 years old women with 66(66.0%). %).  However, prevalence of malaria parasitaemia based on marital status in study population reveals that 51(51.0%) out of 100 women examined were infected with malaria infection. There was significantly higher prevalence among widows with 29(54.7%), followed by 18 (48.6), and followed by 4(40.0%) in single (not married women) respectively. Chi-square analysis shows significant difference between widows, married, single and infection rate (p˃0.05).The study showed a strong correlation between age, marital status and malaria infection among pregnant women in IDPs camps. The morbidity and mortality burden of malaria in the study population among pregnant women in internally displaced persons camps could be reduced drastically by proper prevention strategies, good dietary feeding, good shelter and improving diagnosis.
