However, key information such as sociodemographic characteristics of agents are often missing. This paper aims to compare four methods of classifying social attributes from text. Specifically, we are interested in estimating the gender of German social media creators. By using the example of a random sample of 200 YouTube channels, we compare several classification methods, namely (1) a survey among university staff, (2) a name dictionary method with the World Gender Name Dictionary as a reference list, (3) an algorithmic approach using the website gender-api.com, and (4) a Multinomial Naïve Bayes (MNB) machine learning technique. These different methods identify gender attributes based on YouTube channel names and descriptions in German but are adaptable to other languages. Our contribution will evaluate the share of identifiable channels, accuracy and meaningfulness of classification, as well as limits and benefits of each approach. We aim to address methodological challenges connected to classifying gender attributes for YouTube channels as well as related to reinforcing stereotypes and ethical implications.

It is conducted in the methodological frameworks of Conversation Analysis and Interactional Linguistics – two approaches that consider the interactional aspect of humans talking with each other to be a crucial starting point for its analysis. In doing so, we will (1) lay out the background of this special issue (what is problematic about “chunking” talk-in-interaction, the characteristics of the methodological approach chosen by the contributors, the cesura model), (2) highlight what can be gained from such a revised understanding of “chunking” in talk-in-interaction by referring to previous work with this model as well as the findings of the contributions to this special issue, and (3) indicate further directions such work could take starting from papers in this special issue. We hope to induce a fruitful exchange on the phenomena discussed, across methodological divides.

Negatively charged vesicles containing AOT and phospholipids, in the absence and presence of additional reducing agents (polyampholytes, polyanions or low molecular weight compounds), were used as a template phase to form anisotropic gold nanoparticles. Upon addition of the gold chloride solution, the nucleation process is initiated and both types of particles, i.e., isotropic spherical and anisotropic gold nanotriangles, are formed simultaneously. As it was not possible to produce monodisperse nanotriangles with such a one-step procedure, the anisotropic nanoparticles needed to be separated from the spherical ones. Therefore, a new type of separation procedure using combined polyelectrolyte/micelle depletion flocculation was successfully applied. As a result of the different purification steps, a green colored aqueous dispersion was obtained containing highly purified, well-defined negatively charged flat nanocrystals with a platelet thickness of 10 nm and an edge length of about 175 nm. The NTs produce promising results in surface-enhanced Raman scattering.

BT - articulations of citizenship’s commemorative dimension in Berlin’s cityscape N2 - Historical narratives play an important role in constructing contemporary notions of citizenship. They are sites on which ideas of the nation are not only reaffirmed but also contested and reframed. In contemporary Germany, dominant narratives of the country’s modern history habitually focus on the legacy of the Third Reich and tend to marginalize the country’s rich and highly complex histories of immigration. The article addresses this commemorative void in relation to Berlin’s urban landscape. It explores how the city’s multilayered architecture provides locations for the articulation of marginal memories—and hence sites of urban citizenship—that are often denied to immigrant communities on a national scale. Through a detailed examination of a small celebration in 1965 that marked the anniversary of the founding of the modern Turkish republic, the article engages with the layers of history that coalesce around such sites in Berlin.

Das Wissen darum, dass Gender sozial konstruiert ist, wird von Anti-Gender Aktivist*innen häufig als ‚Gender-Ideologie‘ bezeichnet und ruft heftige Gegenreaktionen hervor. Dies gilt nicht nur in Deutschland – sondern länderübergreifend. Auffällig viele der transnationalen Anti- Gender Mobilisierungen der letzten 20 Jahre finden bezogen auf Bildungseinrichtungen statt. Dieser Beitrag widmet sich der besonderen Rolle der Universität und der Wissenschaft für transnationale Anti-Gender Diskurse. Anhand verschiedener Beispiele zeige ich auf, dass das Verhältnis zwischen Anti-Gender Bewegungen und Wissenschaft geprägt ist von widersprüchlichen Dynamiken, von Abgrenzung aber auch Imitation. In ihrem Zusammenspiel wirken beide Dynamiken mobilisierend und tragen zum Erstarken regressiver Rollenbilder und antidemokratischer rechter Bewegungen in der breiteren Gesellschaft bei. Der letzte Teil des Beitrags ruft daher zu mehr Selbstreflexion der wissenschaftlichen Praxis auf Grundlage feministischer und intersektionaler Ansätze auf.

Grundlagentheoretisch motivierte Arbeit am Begriff „Migration“ ist in der Erwachsenenbildung noch lange nicht hinreichend ausgeschöpft. Auch wenn sich einzelne Studien mit ihm auseinandersetzen, besteht dennoch der Eindruck, dass kategoriale Klärungsversuche singulär bleiben. Die nicht einfache Aufgabe, den Begriff Migration vor seiner kategorialen Stilllegung zu bewahren, bleibt eine ernsthafte Herausforderung für erwachsenenpädagogische Migrationsforschung, sofern sie daran interessiert ist, die Risiken eines bisher essentialistischen Kurses ernsthaft ins Visier zu nehmen. N2 - While the calls to take more notice of the significance of migration for adult education are loud and clear, notably little attention is paid to them with regard to work on categories. In adult education, fundamental theoretical work on definitions of “migration” is still far from complete. Even though individual studies deal with the term, it seems that attempts to clarify categories remain scarce. If adult education research on migration has a genuine interest in examining the risks of the hitherto essentialist course, the none-too simple task of preserving the term “migration” from categorial closedown remains a serious challenge.
