Abstract. The success of social wasps is highly dependent on nest construction and colony maintenance. Species use different strategies to avoid nest predation, including forming associations with other insects and vertebrates. This study describes for the first time the association between the social wasp Chartergus globiventris Saussure and the yellow-olive flycatcher Tolmomyias sulphurescens Spix in a deciduous seasonal forest fragment in southeastern Brazil. We located eight active C. globiventris colonies in the study site, three of which were associated with active T. sulphurescens nests. Bird-wasp associations in previous studies have been regarded as commensalism because only birds seem to benefit. However, further studies are needed to better understand the potential benefits of this relationship for both taxa.Associações de nidificação entre Chartergus globiventris Saussure (Hymenoptera: Vespidae) e Tolmomyias sulphurescens Spix (Passeriformes: Tyrannidae) no sudeste do BrasilResumo. O sucesso das espécies de vespas sociais está relacionado tanto a construção quanto a manutenção das colônias. Várias espécies utilizam de diversas estratégias para evitar a predação de seus ninhos, como a associação com outros insetos e vertebrados. O presente estudo descreve o primeiro registro da associação da vespa social Chartergus globiventris Saussure com a ave Tolmomyias sulphurescens Spix em fragmento de Floresta Estacional Decidual no Sudeste do Brasil. Foram registradas oito colônias de C. globiventris ativas em diferentes espécies arbóreas, das quais três estavam associadas a ninhos ativos de T. sulphurescens. A associação entre a ave e a vespa tem sido tratada como comensalismo, pois apenas a ave obtém vantagens aparente, como discutido na literatura. Contudo, é necessário realizar experimentações ou análises mais aprofundadas a fim de se obter afirmações sobre os benefícios dessa relação.</p

The article covers the issues of initiative acquisition of archives in the documents of personal origin during the Great Patriotic War, the organization of work to identify and collect the wartime documents. Collecting documents of ordinary citizens, in particular letters from the front and to the front is analyzed. Proposals to create the specialized archives of documents on the history of the war were never implemented. Quite a lot of the actions, search operations and expeditions were conducted in the country, for example, the “Chronicle of the Great Patriotic War”, the “Frontline letter”, the “Search”, the “Memory”, etc., during which a significant number of documents of war participants and home front workers were collected and stored. Not so much of the documents of personal origin of the war participants are concentrated in the archives. In general, there prevails the collection type of organization for storing documents from the period of the Great Patriotic War. With reference to the corpus of documents of personal origin of the war period the research literature pays its attention mostly to correspondence and diaries, memoirs. Historians and archivists, analyzing wartime letters, offer different classifications depending on the authors, recipients, subjects, etc. The article provides a generalized classification of letters based on their inherent similarities. The author also analyzes the reasons for a small number of extant diaries and memoirs, and provides examples of their classification. Likewise the article describes current approaches to the collection of personal papers within the frames of the Moscow Glavarkhiv project “Moscow – with care for history” and the Ministry of Defense project “The Memory Road”.

This paper examines the rabbinic concept of impurity in terms of the essence of the reality that this term implies. Did the Rabbis consider impurity to be a force of nature, or rather an abstract formalistic structure devoid of any actual existence? A review of rabbinic sources regarding corpse impurity reveals that the essential structures of tannaitic halakhah are grounded in a natural, immanent perception of impurity, which gave rise to an entire system, intricate and coherent, of “natural laws of impurity.” Layered onto this system, as a secondary stratum of sorts comprising exceptions and “addenda,” is a more subtle halakhic tapestry woven from a diametrically opposed perception. This view subjects the concept of impurity to human awareness and intention, severing it from reality and, in so doing, also stripping it of its “natural” substance.
