The role of Acer negundo L. in plant communities of the Barnaul stripe pine forest is characterized. It wasestablished that in the vicinity of Barnaul the studied communities with maple are represented at all stages of successionassociated with the invasion species penetration. The presence of young individuals of maple and seedlings in the southern part of the Barnaul stripe indicates a further expansion of ash-leaved maple to the south along the Barnaul stripe pineforest.

The satellite images show that the area of marshes in the Kolokolkova bay was notstable during the period from 1973 up to 2011. Until 2010 it varied from 357 to 636 ha. After a severe storm happened on July 24–25, 2010 the total area of marshes was reduced up to 43–50 ha. The mean value of NDVI for studied marshes, reflecting the green biomass, varied from 0.13 to 0.32 before the storm in 2010, after the storm the NDVI decreased to 0.10, in 2011 — 0.03. A comparative analysis of species composition and structure of plant communities described in 2002 and 2011, allowed to evaluate the vegetation changes of marshes of the different topographic levels. They are fol­lowing: a total destruction of plant communities of the ass. Puccinellietum phryganodis and ass. Caricetum subspathaceae on low and middle marches; increasing role of halophytic species in plant communities of the ass. Caricetum glareosae vic. Calamagrostis deschampsioides subass. typicum on middle marches; some changes in species composition and structure of plant communities of the ass. Caricetum glareosae vic. Calamagrostis deschampsioides subass. festucetosum rubrae on high marches and ass. Parnassio palustris–Salicetum reptantis in transition zone between marches and tundra without changes of their syntaxonomy; a death of moss cover in plant communities of the ass. Caricetum mackenziei var. Warnstorfia exannulata on brackish coastal bogs. The possible reasons of dramatic vegetation dynamics are discussed. The dating of the storm makes it possible to observe the directions and rates of the succession of marches vegetation.

This chapter discusses national literary histories in Australia, Canada, New Zealand, and the South Pacific and summarises the book's main findings regarding the construction and revision of narratives of national identity since 1950. In colonial and postcolonial cultures, literary history is often based on a paradox that says much about their evolving sense of collective identity, but perhaps even more about the strains within it. The chapter considers the complications typical of postcolonial literary history by focusing on the conflict between collective celebration and its refutation. It examines three issues relating to the histories of English-language fiction in Australia, Canada, New Zealand, and the South Pacific: problems of chronology and beginnings, with a special emphasis on Indigenous peoples; the role of the cultural elite and the history wars in the Australian context; and the influence of postcolonial networks on historical methodology.

Inspired by recent epistemological and ontological debates aimed at unsettling and reshaping conceptions of language, this essay discusses how mainstream sociolinguistics offers notions meaningful for studying contexts of the South. Based on empirical studies of youth in two African cities, Yaoundé in Cameroon and Maputo in Mozambique, the essay engages with “fluid modernity” and “enregisterment” to unravel the role that fluid multilingual practices play in the social lives of urban youth. The empirically grounded theoretical discussion shows how recent epistemologies and ontologies offer inroads to more pluriversal knowledge production. The essay foregrounds: i) the role of language in the sociopolitical battles of control over resources, and ii) speakers’ reflexivity and metapragmatic awareness of register formations of fluid multilingual practices. Moreover, it shows how bundles of localized meanings construct belongings and counterhegemonic discourses, as well as demonstrating speakers’ differential valuations and perceptions of boundaries and transgressions across social space.

Neste artigo enfoca-se o papel dos visitantes que chegavam à Deutsche Schule urbana, Collegio Allemão de Pelotas, no sul do Rio Grande do Sul, provenientes da Verein für das Deutschtum im Ausland (V.D.A.), (Sociedade de Apoio ao Deutschtum no Exterior), em 1921, 1923, 1924, 1925 e 1933, situada em Hamburgo e Berlim, na Alemanha. O objetivo desses visitantes era inspecionar o projeto educacional alemão e a manutenção do Deutschtum, que mesclava elementos do nacionalismo alemão, vigente, à cultura escolar deste educandário em tempos de Nacionalização do Ensino no Brasil. Consequência dessas visitas era o envio de livros, material didático e professores alemães, bem como a troca de correspondência entre os alunos do educandário de Pelotas e alunos alemães. Trata-se de pesquisa qualitativa, bibliográfica e documental cujas fontes principais são os Relatórios Escolares da Deutsche Schule de Pelotas dos anos 1921, 1923, 1924, 1925 e 1933.* * *This paper focuses on the role of visitors arriving at the urban Deutsche Schule, German College of Pelotas, in the south of Rio Grande do Sul from the Verein für das Deutschtum im Ausland (VDA), a Society for Supporting Deutschtum Abroad, in 1921, 1923, 1924, 1925 and 1933, located in Hamburg and Berlin, Germany. The purpose of these visitors was to inspect the German educational project and the maintenance of the Deutschtum, which merged elements of German nationalism, in force, into the school culture of this educandário in times of Nationalization of Teaching in Brazil. The consequence of these visits was the sending of books, didactic material and German teachers, as well as the exchange of correspondence between the students of the educator of Pelotas and German students. It is a qualitative, bibliographical and documentary research whose main sources are the School Reports of the Deutsche Schule of Pelotas of years 1921, 1923, 1924, 1925 and 1933.

The author who served on the South African Truth and Reconciliation Commission (TRC), focuses on the Hindu experience in South Africa during the apartheid years. At a special TRC Hearing for Faith Communities (East London, 17-19 November 1997) two submissions by local Hindu leaders were tabled. Taking his cues from those submissions, the author discusses four issues: the way the Hindu community suffered during these years, the way in which some members of the Hindu community supported the system of apartheid, the role of Hindus in the struggle against apartheid, and finally the contribution of the Hindu community towards reconciliation in South Africa. In conclusion some notes on how Hindus and Christians may work together in th

This article examines the role of James Burton in the diffusion of military technology in the mid-19th century. Burton worked as the Master Armorer at the Harpers Ferry Armory, as a contractor in the Connecticut Valley, and as an engineer at the Enfield Armory. At each location he incorporated the latest ideas of the American System of Manufacturing. Not only did he transmit new ideas, he visited, studied, and learned from his international peers. When the American Civil War began, he joined the Confederate Ordnance Department and helped the South continue a long and destructive war. The new technological ideas—bred out of necessity of war—continued to help shape the creation of a New South. After the war, Burton influenced weapons manufacturing in Russia, Italy, Turkey, and Egypt. The ideas that Burton helped implement is a case study of international technological diffusion.
