Black dots on dorsal surface. Ventral coloration and annuli numbers same as H. serendipitious n. sp. One pair of eyes close to each other on segment III (Fig. 7E). Male and female gonopores in position similar to H. serendipitious n. sp. Six pairs of testisacs intersegmentally arranged from XII/XIII to XVII/ XVIII; shape similar to H. stagnalis but smaller. Ejaculatory bulbs (atrial cornua) moderately longer, ovoidcylindrical, lying at a much lower level by the sides of the atrium, connected by slender ejaculatory ducts with sharp turn backwards into atrium in XIth segment. Ovisacs large, connected with long and curled common oviduct. Oviduct length almost equal to ovisacs (Figs. 2E, 4E). Six pairs crop caeca, 6th directed backwards and short, extending up to fourth intestinal caecum. Four pairs intestinal caecum, first two pairs slightly curved upward, third pair flat and last pair curved downward. Rectum short, “S” shaped, similar H. stagnalis (Figs. 3E, 5E). The dorsal nuchal scute of H. stagnalis from Europe has been depicted in a SEM-micrograph by Sawyer (1986, p. 538). Additional SEM identified differences in scute morphology and position between species (Fig. 8). Specifically, the s cute of Helobdella spp. ranged from rhomboidal to hexagonal, settled on the12th and extending to the 13th annulus The H. modesta scute was square-shaped, settled on the 12th annulus (on the VII-a1) and sometimes extending up to half the 13th annulus (Fig. 6B). The H. serendipitious scute was pentagonal, settled in the dorsal surface of segment VII-a2 (on annulus 12) (Fig. 6C). The Helobdella eriensis n. sp. (Farm Pond) scute was similar to H. serendipitious n. sp. but settled in the 12th and up to all of 13th annulus (Fig. 6D). The Helobdella echoensis n. sp. (York, PA) was similar to H. serendipitious n. sp. but mushroom shaped (Fig. 5E).Published as part of Saglam, Naim, Kutschera, Ulrich, Saunders, Ralph, Saidel, William M., Balombini, Katherine L.

What to do with conspiracy theories?: Insights from contemporary Turkey
No full textThis article presents ethnographic insights into the everyday lives of people who circulate conspiratorial narratives through an ethnographic study of ultranationalist men in contemporary Turkey. Drawing on the findings of this research, the author suggests that conspiratorial discourses should be examined not solely in terms of their (anti‐)truth qualities but as social practices through which masculine subjectivities and socialities are engendered. The author then explores how the circulation of conspiratorial narratives forges agency and political subjectivity for the men involved, while also inducing sociopolitical effects such as vigilantism and paramilitary violence. This article contends that through the circulation of conspiratorial narratives and everyday engagements with vigilantism and extralegal violence, the men reconfigure sovereignty and the way that the state operates in contemporary Turkey. The findings of this research suggest that the focus should be moved away from the epistemological shortcomings of conspiratorial narratives or strategies to debunk them – such as fact‐checking – which presume that exposure of ‘the truth’ would lead to the dissolution of ‘untruthful’ conspiracies. Rather, the author suggests that researchers attend to the particular forms conspiracies take in concrete situations, how they mould political subjectivities and social groups and reconfigure the ways that the state operates alongside the law in other similar settings. </p

Glasba brez meja:: raziskovalni primer o novih metodologijah poučevanja glasbe na dunajskih osnovnih in srednjih šolah
No full textThis article presents some of the results of a research project which the author conducted between 2015 and 2018. The influences of the music lessons which were offered within the framework of this research project is the main subject of this article. It shows how children with and without migrant backgrounds can improve their bi- and multi-musical identities in their transcultural spaces through these music lessons. Providing an insight into possibilities of intercultural music education in Viennese primary schools is the central aim of this paper.Članek predstavlja nekatere rezultate projekta, ki ga je avtorica izvajala med letoma 2015 in 2018. Glavna tema prispevka je vpliv pouka glasbe, kateremu so učenci prisostvovali v okviru dotičnega raziskovalnega projekta. Članek pokaže, kako lahko otroci – z migrantskim ozadjem ali brez – s poukom glasbe okrepijo svoje dvo- ali večglasbene identitete v medkulturnih prostorih. Ključni namen pričujočega članka je predstaviti vpoglede v različne možnosti medkulturne glasbene vzgoje na dunajskih osnovnih šolah
