Bakhtin, Russia and World: Reception of Scientist’s Ideas and Works in 1996—2020 Research

The process of reception of M. M. Bakhtin’s scientific heritage over the past 25 years is analyzed in the review article. The focus of the authors is on identifying the stages and main directions, trends and achievements of modern Russian Bakhtin studies, determining the prospects for further research. The relevance of the review lies in the need for an objective reconstruction of the process of studying the ideas and heritage of M. M. Bakhtin in Russia and abroad, primarily over the past 25 years. It is noted that the works of M. M. Bakhtin are the most cited in scientific literary criticism and Bakhtin studies have become an independent branch of interdisciplinary research. The analysis revealed the role in the development of Russian Bakhtin studies of such a phenomenon as a collection of works by a scientist, Bakhtin studies journals and publications, publications of leading researchers. Conclusions are made that in 1996—2020 Russian Bakhtin studies have reached a fundamentally new level in the development of the scientist’s heritage, made a significant contribution to the study of his key ideas and concepts, completed a preliminary reconstruction of his scientific biography, carried out a systematic description of his terminological language and scientific theory as a whole, indicated the points of the necessary dialogue between Russian scientists and foreign colleagues

Nano-engineered electron–hole exchange interaction controls exciton dynamics in core–shell semiconductor nanocrystals

A strong electron–hole exchange interaction (EI) in semiconductor nanocrystals (NCs) gives rise to a large (up to tens of meV) splitting between optically active ('bright') and optically passive ('dark') excitons. This dark–bright splitting has a significant effect on the optical properties of band-edge excitons and leads to a pronounced temperature and magnetic field dependence of radiative decay. Here we demonstrate a nanoengineering-based approach that provides control over EI while maintaining nearly constant emission energy. We show that the dark–bright splitting can be widely tuned by controlling the electron–hole spatial overlap in core–shell CdSe/CdS NCs with a variable shell width. In thick-shell samples, the EI energy reduces to <250 μeV, which yields a material that emits with a nearly constant rate over temperatures from 1.5 to 300 K and magnetic fields up to 7 T. The EI-manipulation strategies demonstrated here are general and can be applied to other nanostructures with variable electron–hole overlap

Collective Memory in P. Everett’s Novel “I Am Not Sidney Poitier”

This article deals with one of Percival Everett’s latest novels. In his novel, he addresses an image of Sydney Poitier who was an icon of the 60s of the 20th century, one of the representatives of the movement for the rights of African Americans in the USA. The authors of the article conclude that the novel has the same plot structures as movies that Sydney Poitier starred. The main aim of appealing to the film heritage is to present traditional views and prejudices of American society towards racial discrimination and slavery, identity, and race.Este artículo trata de una de las últimas novelas de Percival Everett. En su novela, aborda una imagen de Sydney Poitier, quien fue un ícono de los años 60 del siglo XX, uno de los representantes del movimiento por los derechos de los afroamericanos en los Estados Unidos. Los autores del artículo llegan a la conclusión de que la novela tiene las mismas estructuras argumentales que las películas protagonizadas por Sydney Poitier. El objetivo principal de apelar al patrimonio cinematográfico es presentar los puntos de vista y prejuicios tradicionales de la sociedad estadounidense hacia la discriminación racial y la esclavitud, la identidad y la raza
