Of âraisinsâ and âyeastâ: mobilisation and framing in the East German revolution of 1989
There is no shortage of literature on the social movements that arose in East Germany in 1989. Numerous studies have shed light upon the nature, scale and dynamics of the uprising of that year. But on certain issues questions remain. No consensus exists, for example, on the relationship between the âcivic groupsâ (New Forum, Democratic Awakening, etc.) and the street protests of the autumn of 1989. Were these simply two facets of a single movement? Or are they better characterised as two distinct streams within the same movement delta? Did the street protests push the civic movement activists into the limelight? Or is it more accurate to say, with Reinfried Musch, that âthe civic movement brought the people onto the streetsâ?1 This paper considers two contrasting interpretations of these issues, and finds both wanting. An alternative interpretation is offered, one that draws upon Marc Steinberg's âdialogicalâ development of frame theory

Pentaplacodinium saltonense gen. et sp. nov. (Dinophyceae) and its relationship to the cyst-defined genus Operculodinium and yessotoxin-producing Protoceratium reticulatum
Strains of a dinoflagellate from the Salton Sea, previously identified as Protoceratium reticulatum and yessotoxin producing, have been reexamined morphologically and genetically and Pentaplacodinium saltonense n. gen. et sp. is erected to accommodate this species. Pentaplacodinium saltonense differs from Protoceratium reticulatum (ClaparĂšde et Lachmann 1859) BĂŒtschli 1885 in the number of precingular plates (five vs. six), cingular displacement (two widths vs. one), and distinct cyst morphology. Incubation experiments (excystment and encystment) show that the resting cyst of Pentaplacodinium saltonense is morphologically most similar to the cyst-defined species Operculodinium israelianum (Rossignol, 1962) Wall (1967) and O. psilatum Wall (1967). Collections of comparative material from around the globe (including Protoceratium reticulatum and the genus Ceratocorys) and single cell PCR were used to clarify molecular phylogenies. Variable regions in the LSU (three new sequences), SSU (12 new sequences) and intergenic ITS 1-2 (14 new sequences) were obtained. These show that Pentaplacodinium saltonense and Protoceratium reticulatum form two distinct clades. Pentaplacodinium saltonense forms a monophyletic clade with several unidentified strains from Malaysia. LSU and SSU rDNA sequences of three species of Ceratocorys (C. armata, C. gourreti, C. horrida) from the Mediterranean and several other unidentified strains from Malaysia form a well-supported sister clade. The unique phylogenetic position of an unidentified strain from Hawaii is also documented and requires further examination. In addition, based on the V9 SSU topology (bootstrap values >80%), specimens from Elands Bay (South Africa), originally described as Gonyaulax grindleyi by Reinecke (1967), cluster with Protoceratium reticulatum. The known range of Pentaplacodinium saltonense is tropical to subtropical, and its cyst is recorded as a fossil in upper Cenozoic sediments. Protoceratium reticulatum and Pentaplacodinium saltonense seem to inhabit different niches: motile stages of these dinoflagellates have not been found in the same plankton sample
