Aboveground plant biomass from the Jena Experiment (Monocultures, year 2004)

This data set contains aboveground plant biomass in 2004 (Sown plant community, Weed plant community, Dead plant material, and Unidentified plant material; all measured in biomass as dry weight) of the monoculture plots of a large grassland biodiversity experiment (the Jena Experiment). In the monoculture plots the biomass of the sown plant community contains only a single species per plot and this species is a different one for each plot. Which species has been sown in which plot is stated in the plot information table for monocultures (see further details below). The monoculture plots of 3.5 x 3.5 m were established for all of the 60 plant species of the Jena Experiment species pool with two replicates per species. These 60 species comprising the species pool of the Jena Experiment belong to four functional groups (grasses, legumes, tall and small herbs). Plots were sown in May 2002 and are since maintained by bi-annual weeding and mowing. Aboveground plant biomass was harvested twice in 2004 just prior to mowing (during peak standing biomass in early June and in late August) on all experimental plots of the monocultures. This was done by clipping the vegetation at 3 cm above ground in 2 rectangles of 0.2 x 0.5 m per plot. The location of these rectangles was assigned prior to each harvest by random selection of coordinates within the core area of the plots (i.e. excluding an outer edge of 0.5 m). The positions of the rectangles within plots were identical for all plots. The harvested biomass was sorted into categories: sown plant species, weed plant species (species not sown at the particular plot), detached dead plant material (i.e., dead plant material in the data file), and remaining plant material that could not be assigned to any category (i.e., unidentified plant material in the data file). All biomass was dried to constant weight (70°C, >= 48 h) and weighed. The data for individual subsamples (i.e. rectangles) and the mean over samples for all biomass measures are given.

Duration of a flood along a plant diversity gradient in the Jena Experiment (Main Experiment, June 2013)

The Jena Biodiversity Experiment is located on a Central European mesophilic floodplain on the banks of the Saale River (see further details below). In the main experiment, 82 grassland plots of 20 x 20 m were established from a pool of 60 species belonging to four functional groups (grasses, legumes, tall and small herbs). In May 2002, varying numbers of plant species from this species pool were sown in the plots to create a gradient of plant species richness (1, 2, 4, 8, 16 and 60 species) and functional richness (1, 2, 3, or 4 functional groups). Plots were maintained by bi-annual weeding and mowing. In June 2013, a natural 200-year flood event occurred at the field site. Rainfall in May 2013 in Jena was ~150mm, constituting >25% of annual precipitation at the site that year. Overall the flood affected the entire Elbe River Basin and much of Europe and was one of the largest natural flooding events in the past two centuries. The flood lasted for a total of 24 days at the site (30 May-24 June) and led to anaerobic soil conditions. Due to small topographical differences among the plots in the experiment (<1m), there was variation in the duration of flooding and the proportion of each plot that was flooded. This variation was well-distributed across the diversity gradient. To assess the importance of flood severity, the proportion of each plot that was flooded was estimated by eye (using five classes: 0 completely dry, 0.25 up to a quarter under water, 0.5 half, 0.75 up to three quarters under water, and 1 more than three quarters under water up to completely submerged). These values, for each of the 24 days that the flood lasted, were summed up to calculate a flooding index. The resulting flooding index is given for each plot of the Main Experiment.

"Dem Volk eine andere Muttersprache geben". Zur Diskussion über Zweisprachigkeit und Erziehung in der Geschichte der Volksschule

Ausgangspunkt der Überlegungen sind die aktuellen Forderungen nach einem veränderten Umgang mit gesellschaftlicher Zwei- und Mehrsprachigkeit angesichts internationaler Migration und europäischer Integration. Im Rückblick auf die Geschichte der bildungspolitischen und pädagogischen Diskussion über Zweisprachigkeit und öffentliche Erziehung werden - unter Einbeziehung der internationalen Diskussion - vor allem die "Logiken" der pädagogischen Argumentation herausgearbeitet, die in den Auseinandersetzungen im Kaiserreich und in der Weimarer Republik entwickelt worden sind. Die hier vertretene Annahme ist, daß die historisch entwickelten "Logiken", als zum jeweiligen historischen Zeitpunkt plausible, so in die Normalitätsbeschreibungen von Erziehung und Bildung eingegangen sind, daß sie schließlich wie Naturgegebenheiten erscheinen (konnten) und daher - trotz und gegen Aufklärung und bessere(r) Einsicht - bildungspolitisches, bildungsadministratives und pädagogisches Handeln bis heute bestimmen.

Bowling for fascism: Social capital and the rise of the Nazi Party in Weimar Germany, 1919-33

Social capital a dense network of associations facilitating cooperation within a community typically leads to positive political and economic outcomes, as demonstrated by a large literature following Putnam. A growing literature emphasizes the potentially "dark side" of social capital. This paper examines the role of social capital in the downfall of democracy in interwar Germany by analyzing Nazi party entry rates in a cross-section of towns and cities. Before the Nazi Party's triumphs at the ballot box, it built an extensive organizational structure, becoming a mass movement with nearly a million members by early 1933. We show that dense networks of civic associations such as bowling clubs, animal breeder associations, or choirs facilitated the rise of the Nazi Party. The effects are large: Towns with one standard deviation higher association density saw at least one-third faster growth in the strength of the Nazi Party. IV results based on 19th century measures of social capital reinforce our conclusions. In addition, all types of associations veteran associations and non-military clubs, "bridging" and "bonding" associations positively predict NS party entry. These results suggest that social capital in Weimar Germany aided the rise of the Nazi movement that ultimately destroyed Germany's first democracy.

The revival of international solidarity : the Internationale Arbeiterhilfe, Willi Münzenberg and the Comintern in Weimar Germany, 1921-1933

The aim of the study is to write the first comprehensive history of the Internationale Arbeiterhilfe (International Workers’ Relief) and its message of international solidarity during the Weimar Republic, 1921–1933. The Arbeiterhilfe was the Communist International’s (Comintern) primary international solidarity organisation of the time. The work is identified as a contribution to the transnational history of the interwar period as its main focus is not on governmental politics or intra-state relations, but is focused on the transnational world of an international organisation. The history of the Arbeiterhilfe provides the main springboard from which to write a contextually-based analysis of international solidarity during the Weimar Republic. The study highlights for the first time the importance of the German communist Willi Münzenberg (1889–1940), as the leader of the Arbeiterhilfe, in the history of international solidarity. The main question of this study is how an explicit use of language coupled with the visualisation and practices of solidarity were created through the Arbeiterhilfe. How was solidarity actually envisaged, organised and brought to life by the Arbeiterhilfe in Weimar Germany? How did its expressions of solidarity change over time? Throughout the thesis, the changing and complex character of solidarity is analysed. How was the Arbeiterhilfe’s message of solidarity created and changed in relation to the Comintern and the Soviet Union’s policies? How did the Arbeiterhilfe create a new culture of international solidarity thought film, cinema, illustrated newspapers and the organising of mass spectacles of international solidarity? The Arbeiterhilfe had its international headquarters in Berlin which functioned as the base, one could argue, for some of the inter-war period’s most spectacular solidarity campaigns. The Arbeiterhilfe constitutes a significant case study of an early international organisation as it was one of the first international organisations for global (albeit not universal) international solidarity which had unparalleled prospects to develop new transnational identifications and social ties. It could consequently be suggested that the Arbeiterhilfe in several ways could be perceived as a predecessor to several post-1945 transnational solidarity organisations and International Non-Governmental Organisations (INGOs).

Persecution perpetuated: The medieval origins of anti-semitic violence in Nazi Germany

How persistent are cultural traits? This paper uses data on anti-Semitism in Germany and finds continuity at the local level over more than half a millennium. When the Black Death hit Europe in 1348-50, killing between one third and one half of the population, its cause was unknown. Many contemporaries blamed the Jews. Cities all over Germany witnessed mass killings of their Jewish population. At the same time, numerous Jewish communities were spared these horrors. We use plague pogroms as an indicator for medieval anti-Semitism. Pogroms during the Black Death are a strong and robust predictor of violence against Jews in the 1920s, and of votes for the Nazi Party. In addition, cities that saw medieval anti-Semitic violence also had higher deportation rates for Jews after 1933, were more likely to see synagogues damaged or destroyed in the Night of Broken Glass in 1938, and their inhabitants wrote more anti-Jewish letters to the editor of the Nazi newspaper Der Stürmer.

Against the mainstream: Nazi privatization in 1930s Germany

The Great Depression spurred State ownership in Western capitalist countries. Germany was no exception; the last governments of the Weimar Republic took over firms in diverse sectors. Later, the Nazi regime transferred public ownership and public services to the private sector. In doing so, they went against the mainstream trends in the Western capitalist countries, none of which systematically reprivatized firms during the 1930s. Privatization in Nazi Germany was also unique in transferring to private hands the delivery f public services previously provided by government. The firms and the services transferred to private ownership belonged to diverse sectors. Privatization was part of an intentional policy with multiple objectives and was not ideologically driven. As in many recent privatizations, particularly within the European Union, strong financial restrictions were a central motivation. In addition, privatization was used as a political tool to enhance support for the government and for the Nazi Party.
