We address the external effects on public sector efficiency measures acquired using Data Envelopment Analysis. We use the health care system in Russian regions in 2011 to evaluate modern approaches to accounting for external effects. We propose a promising method of correcting DEA efficiency measures. Despite the multiple advantages DEA offers, the usage of this approach carries with it a number of methodological difficulties. Accounting for multiple factors of efficiency calls for more complex methods, among which the most promising are DMU clustering and calculating local production possibility frontiers. Using regression models for estimate correction requires further study due to possible systematic errors during estimation. A mixture of data correction and DMU clustering together with multi-stage DEA seems most promising at the moment. Analyzing several stages of transforming society’s resources into social welfare will allow for picking out the weak points in a state agency’s work.
This article is about the life of Dmitry Bystroliotov (1901-1975), a Soviet intelligence officer, about his adventures in the Sahara desert and the Congo in the 1930s. Some information about Bystroliotov and about his trip emerged many years after his death, in the 1990s. But even today much of the story remains mysterious. Bystroliotovs first publications although a mystery too appeared in our journal in 1963. We continue the story on the basis of what has come to light since then.

The authors discuss why conflicts emerge and how they are settled in different African regions and countries. Prospects for their peaceful resolution are studied. Basing on case studies, the authors propose theoretical approaches to conflicts.
HIV first appeared in West-Central Africa, then spread to the South, East and West and, at the same time, practically did not reach North Africa. A possible explanation of this pattern could be in the role of Islam which pays particular attention to the prevention of extramarital sexual relations. In addition, one can mention that circumcised men suffer from HIV significantly less frequently than non-circumcised. Against such background, we had certain grounds to expect that Islamic societies would have lower levels of HIV prevalence than non-Islamic. Our cross-cultural tests have supported this hypothesis. The data have been analyzed with power-law regression. We have found a significant (p < .001) and really strong (r = -.747) negative power-law correlation between percentage of Muslims and the HIV prevalence in African countries. Of course, one should take into account that the stigma attached to HIV is also much higher among Muslims and so, Muslims tend to be tested, identified and monitored at lower numbers than those from other religious and cultural backgrounds, which implies that further in-depth research is necessary in order to detect the real relationship between variables in question.
