The article aims to review the political developments in African states throughout their recent post-colonial past. Uprooting political violence & anchoring a stable structure based on a society-wide consensus being just two of the several prerequisites for solving so many other problems which trouble Africa today, this article aims to diagnose at least some root causes & consequences of the generally unsatisfactory political situation on the continent. Having identified a set of political instability symptoms (coups d'etat, civil wars, failed putches etc.) the author first ranks African states according to their political instability rate. On the basis of statistical correlation analysis, the author then investigates the relation between political instability in Africa & a number of quantifiable geographical, demographical, military & economic variables. The author has identified some dispositions increasing -- though with only small statistical significance -- the probability of instability in African states. In order of importance, these include: large territory, high illiteracy rate, low urbanization, high number of ethnic groups living within the territory, & large population. Also, there is a close link between political instability & governmental military spending. It probably has a negative impact on a number of key economic indicators, be it GDP growth, GDP per capita levels, domestic savings, or price level developments. In the final part of his article, the author makes a brief summary of political developments in African countries in the 21st century. Tables, Appendixes, References.

For all 60 years of the existence of the University of Economics, Prague (UEP) was statistics one of the taught compulsory course, and here also took place the specialized studies of statistics, which predecessor was Statistical and Actuarial engineering at the University of Special Sciences (within the Czech Technical University). The article focuses on the 50's, when at the UEP existed the independent Faculty of Statistics and when the lessons of statistics were difficulty exempted from the Stalinist dogmatism. Between the personalities is mentioned prof. Benedikt Korda (1914- 2010), who was the most famous person in the first period of Faculty, (there will be mentioned his remarkable CV), prof. Lubomir Cyhelsky (*1929), who was the head of the department in 1962-1990, and prof. Jiri Likes (1929-1994) as well, who was internationally acclaimed scientists in the theory of probability and mathematical statistics, whose name is used for one of the greatest lecture hall at the University. Since 1991 there exist at the Faculty of Informatics and Statistics the Department of Statistics and Probability (17 internal teachers and 13 internal PhD students), the Department of Economic Statistics (6 + 3) and the Department of Demography (6 + 4).

The article draws on the concept of 'replacement migration', widely presented by the Population Division of the UN Department of Economic and Social Affairs in 2000 and 2001, which elaborated a concept and conducted a comprehensive analysis of international migration as a solution to the problem of population declines and demographic ageing. This concept was applied as an example to selected countries in the world, the European region, and the European Union as a whole. It involves calculating the number of foreign migrants necessary to completely offset future changes in the size or age structure of the given country's population as a result of the predicted demographic trends. The following article describes the formulation of this concept and looks at its application on a general methodological level and in the specifi c case of the Czech Republic. A detailed description is given not just of the model used but also of its internal and external assumptions. The constructed model is then applied towards determining the, necessary number of 'replacement migrants' in order to prevent a signifi cant change in the Czech Republic in: 1) the total size of the population, 2) the average age of the population, 3) the percentage of people of working age, and 4) the ratio of people of post-productive to productive age. With the aid of the results the authors clearly demonstrate that while international migrants could effectively help maintain the current size of the population, they would not be able to prevent the continued ageing of the population or even have a decisive impact on the course of this process. With these fi ndings the authors hope to contribute to the debate on the topic of the ageing population in the Czech Republic, and they call strongly for more intensive and especially more effective preparations for this real and unavoidable era in the development of Czech society.
