The main objective of this paper is to analyze the (1, λ) evolution strategy by use of stochastic approximation methods. Both constant and decreasing step size algorithms are studied. Convergence and estimation error bounds for the (1, λ) evolution strategy are developed. First the algorithm is converted to a recursively defined scheme of stochastic approximation type. Then the analysis is carried out by using the analytic tools from stochastic approximation. In lieu of examining the discrete iterates, suitably scaled sequences are defined. These interpolated sequences are then studied in detail. It is shown that the limits of the sequences have natural connections to certain continuous time dynamical systems.

The concepts of expectation, anomaly, and unexpectedness that Philip J. Deloria developed in Indians in Unexpected Places (2004) have shaped a wide range of interdisciplinary research projects. In the process, those terms have changed the ways it is possible to think about American Indian representation, cosmopolitanism, and agency. This article revisits my own work in this area and provides a short survey of related scholarship in order to reassess the concept of unexpectedness in the present moment and to consider the ways my deployment of it might change in order to better meet the needs of my students. To begin a process of engaging intergenerational perspectives on this subject, the article concludes with an interview with Dr. Jacob E. Perea, dean emeritus of the Graduate College of Education at San Francisco State University and a veteran of the 1969 student strikes that founded the College of Ethnic Studies at San Francisco State University.

On September, 21-23, the I.A. Bunin Yelets State University, supported by the Russian Foundation for Basic Research (RFFI), held an All-Russian scientific conference ‘In the time of change: Revolt, insurrection, and revolution in the Russian periphery in the 17th – early 20th centuries’. Scientists from various Russian regions participated in its work. The conference organizers focused on social conflicts in the Russian periphery. The first series of reports addressed the Age of Rebellions in the Russian history. They considered the role and the place of the service class people in anti-government revolts. Some scientists stressed the effect of official state policy on the revolutionary mood of the people. Some reports paid attention to jurisdictions and activities of the general police in the 19th – early 20th century and those of the Provisional Government militia. Other reports analyzed the participation of persons of non-peasant origin in the revolutionary events. They studied the effect of the revolutionary events on the mood and behavior of local people and the ways of solving conflicts between the authorities and the society. Most numerous series of reports were devoted to social conflicts in the Russian village at the turn of the 20th century, studied forms and ways of peasants' struggle against the extortionate cost of the emancipation, and offered a periodization of peasants' uprisings. The researchers stressed that peasants remained politically unmotivated; analysis of their relations with authorities shows that they were predominantly conservative and not prone to incitement to against monarchy. Some questions of source studies and methodology of studying the revolution and the preceding period were raised. Most researches used interdisciplinary methods, popular in modern humanities and historical science.

On October 12th and 13th, 2020, Bryansk State University held an international scientific online conference "Vegetation of Eastern Europe and Northern Asia". The Proceedings of abstracts includes 66 reports by 118 authors and co-authors from 5 countries, 34 localities and 51 organizations. During the meeting, 41 oral presentations were made. In conclusion, it was noted that it is necessary to promote an integration of geobotanists and florists from different regions in order to implement joint research projects. In particular, this concerns a project of making a vegetation classification in Russia.
