Obstruction theory for operadic algebras
Dimitrova, Boryana (2012-05-21)We study obstruction theory for formality of chain operadic algebras. We construct a canonical class γ<sub>A</sub> for an algebra A over a cofibrant chain operad P<sub>∞</sub>. This class takes values in the Gamma cohomology ... -

Daum, Thomas (2018-07)In Africa, policymakers and development practitioners focus heavily on making farming more attractive for the youth. To reach this goal, different actions are proposed, often emphasising the need for modern technology. ... -
Of Liars and Deniers: The Credibility-Concealed Information Test as a Response Time-Based Measure for Credibility Assessment in Suspects and Witnesses
Eickmeier, Kathrin (2020-02-26)There are numerous studies on polygraphs like the Concealed Information Test (CIT) that aim to detect whether a suspect possesses crime-related knowledge. In contrast, not a single psychophysiological or behavioral paradigm ... -
Of Trackers and Tractors. Using a Smartphone App and Compositional Data Analysis to Explore the Link Between Mechanization and Intra-Household Allocation of Time in Zambia
Daum, Thomas; Capezzone, Filippo; Birner, Regina (2019-05)Digital tools may help to study socioeconomic aspects of agricultural development that are difficult to measure such as the effects of new technologies, policies and practices on the intra-household allocation of time. As ... -
Off the Grid: Environmental Degradation and Citizenship at the Margins
Harms, Arne (2015-05)In this paper I have presented some preliminary thoughts on political repercussions of environmental degradations on the margins. In order to do that I have embraced two approaches derived from political theory. First, I ... -
