The article analyses the determinants of job mobility of young workers on the Russian labor market as well as the impact of high level of job mobility on future wages. The analysis is based on the data of the Russia Longitudinal Monitoring Survey (RLMS) for 2000–2010. The results show that mobility decreases as the person ages; more educated young workers change their jobs more often than less educated ones. The estimations also show that 1 or 2 moves during 4 years (compared to zero moves) positively affect future wages, whereas 3 moves during 4 years do not have significant impact on it.
We consider dynamics of a space elevator on an asteroid, i. e., spacecraft attached to a rotating celestial body with a light inextensible tether. We study the domains attainable for the spacecraft depending on such problem parameters as the angular velocity of the asteroid, the tether length, the position of the anchor at the surface, etc. We develop a method based on Routh procedure that allows one to identify the relative equilibria of the system in study and to analyze its stability and bifurcations. Some non-trivial classes of the solutions are found and their relations to the libration points are examined.
This article is talking about state management and cultural policy, their nature and content in term of the new tendency - development of postindustrial society. It mentioned here, that at the moment cultural policy is the base of regional political activity and that regions can get strong competitive advantage if they are able to implement cultural policy successfully. All these trends can produce elements of new economic development.
