Consequently, youth from poor households disproportionately frequently participate in disability-specific programs aiming to improve their educational levels and labor market opportunities. They face a double burden of disability and poverty. In our study, we look at poor and non-poor youth with disabilities (YPWD) who participate in vocational rehabilitation (VR) and whether VR helps them (a) in transitioning into employment and (b) in leaving poverty. We examine the association between the receipt of initial basic income support (BIS) as a poverty indicator, later labor market outcomes, and earned vocational qualification using administrative data. We make use of a sample of all persons accepted for VR in 2010 (N = 36,645). We employ logit models on VR attendees' labor market outcomes three and five years after being accepted for VR as well as on their earned vocational qualifications. Beside initial poverty status, we control for educational level, type, and degree of disability and program pattern during the VR process. Our findings show that YPWD from poor households have a decreased likelihood of a vocational certificate and employment. Additionally, they are more likely to receive BIS than young people not from poor households and thus more likely to remain poor. In conclusion, VR seems to support poor YPWD less in their school-to-work transitions. Thus, disability-specific programs should be more tailored to the social situations of participants, and counsellors should be more sensitive to their social backgrounds.}, language = {en} } @article{Manthe2021, author = {Manthe, Barbara}, title = {On the Pathway to Violence: West German Right-Wing Terrorism in the 1970s}, series = {Terrorism and Political Violence}, volume = {33}, journal = {Terrorism and Political Violence}, number = {1}, publisher = {Taylor \& Francis}, issn = {0954-6553}, doi = {10.1080/09546553.2018.1520701}, pages = {49 -- 70}, year = {2021}, language = {en} } @inproceedings{GalleArellanoCondeetal.2015, author = {Galle, Bo and Arellano, Santiago and Conde, Vladimir and Pfeffer, Melissa and Barsotti, Sara and Stefansdottir, Gerður and Bergsson, Baldur and Bergsson, Bergur and Ingvarsson, Thorgils and Weber, Konradin}, title = {Ground based measurements of the gas emission from the Holuhraun volcanic fissure eruption on Iceland 2014/2015}, series = {Geophysical Research Abstracts: EGU General Assembly 2015}, volume = {17}, booktitle = {Geophysical Research Abstracts: EGU General Assembly 2015}, publisher = {Copernicus}, address = {G{\"o}ttingen}, year = {2015}, abstract = {The since 31 August 2014 ongoing volcanic eruption at Holuhraun on Iceland is by far the strongest source of sulfur dioxide in Europe over the last 230 years with sustained emission rates exceeding 100 000 ton/day. This gas emission severely affects local population and has become a concern also for air traffic. The eruption has in December continued at constant pace for 3.5 months. Three scenarios are envisaged for the future; (1) the eruption stops, (2) the fissure extends under the Vattnaj{\"o}kul glacier and (3) Bardarbunga volcano erupts. The two later scenarios will cause increased gas emission, severe ash emissions and extended flooding. Under the scope of the EU-project FUTUREVOLC, a project with 3.5 years duration, aiming at making Iceland a supersite for volcanological research as a European contribution to GEO, we are developing a version of the Scanning DOAS instrument that is adapted to high latitudes with low UV radiation and severe meteorological conditions. Since the first day of the eruption several of these novel instruments has been monitoring the SO2 emission from the eruption. Data from our instruments are still after 3.5 months the only sustained ground-based monitoring of this gas emission. A lot of work is however needed to sustain this operation at a very remote site and under severe field conditions. At the same time the very high concentrations in the gas plume, in combination with bad meteorological conditions require the development of novel methods to derive reliable flux estimates. In this presentation we will discuss the instrumental issues and present the latest version of the emission estimates made from our measurements.}, subject = {Vulkanismus}, language = {en} } @inproceedings{WeberEliassonArnasonetal.2015, author = {Weber, Konradin and Eliasson, Jonas and Arnason, Gylfi and R{\"o}gnvaldsson, {\´O}lafur and Thorsteinsson, Throstur and Palsson, Thorgeir and B{\"o}hlke, Christoph and Fischer, Christian and Smith, Paul and Jones, Roderic L. and Tirpitz, Lukas and Platt, Ulrich}, title = {Airborne Investigations and WRF - Model Calculations of the Bardarbunga-Holuhraun Eruption Plume}, series = {Geophysical Research Abstracts: EGU General Assembly 2015}, volume = {17}, booktitle = {Geophysical Research Abstracts: EGU General Assembly 2015}, publisher = {Copernicus}, address = {G{\"o}ttingen}, year = {2015}, abstract = {The eruption in Holuhraun is the largest producer of lava and gas in Iceland since 1783. The Volcanic Ash Research (VAR) group organized an airborne measurement campaign including 10 flights, where emissions of SO2 and ash concentrations were measured at the source and at the far plume. The highest SO2 concentration at the source was nearly up to 100 mg/m3. This is an extremely high value, compared to other airborne campaigns and a contamination considered to cause serious illness by the Icelandic Directorate of Health. Volcanic ash consisted of very fine particles, but the concentration was low when compared to other recent eruptions. Measurements of the far plume showed that scavenging is very active. The dispersion was successfully modeled with the Weather Research and Foreast (WRF-chem) model and analysis using the model showed that a large amount of the sulphur was precipitated in the Icelandic highlands.}, subject = {Vulkanismus}, language = {en} } @article{EliassonYoshitaniWeberetal.2014, author = {Eliasson, Jonas and Yoshitani, Junichi and Weber, Konradin and Yasuda, Nario and Iguchi, Masato and Vogel, Andreas}, title = {Airborne Measurement in the Ash Plume from Mount Sakurajima: Analysis of Gravitational Effects on Dispersion and Fallout}, series = {International Journal of Atmospheric Sciences}, volume = {2014}, journal = {International Journal of Atmospheric Sciences}, publisher = {Wiley}, issn = {2314-4122}, doi = {10.1155/2014/372135}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-50955}, pages = {16}, year = {2014}, abstract = {Volcanic ash concentrations in the plume from Sakurajima volcano in Japan are observed from airplanes equipped with optical particle counters and GPS tracking devices. The volcano emits several puffs a day. The puffs are also recorded by the Sakurajima Volcanological Observatory. High concentrations are observed in the puffs and fallout driven by vertical air current, called streak fallout. Puffs dispersion is analyzed by the classical diffusion-advection method and a new gravitational dispersion method. The fluid mechanic of the gravitational dispersion, streak fallout, and classical diffusion-advection theory is described in three separate appendices together with methods to find the time gravitational dispersion constant and the diffusion coefficient from satellite photos. The diffusion-advection equation may be used to scale volcanic eruptions so the same eruption plumes can be scaled to constant flux and wind conditions or two eruptions can be scaled to each other. The dispersion analyses show that dispersion of volcanic plumes does not follow either theories completely. It is most likely diffusion in the interface of the plume and the ambient air, together with gravitational flattening of the plumes core. This means larger boundary concentration gradients and smaller diffusion coefficients than state of the art methods can predict.}, subject = {Vulkanismus}, language = {en} } @article{MaginKoestersJanduraetal.2025, author = {Magin, Melanie and K{\"o}sters, Raphael and Jandura, Olaf and Weiß, Ralph and Stark, Birgit and Udris, Linards and Klein, Miriam and Riedl, Andreas A.}, title = {Viewpoint Diversity, Balance, Deliberativeness: Assessing the Media Performance of Migration Coverage Multi-Dimensionally Based on Deliberative Democratic Theories}, series = {Mass Communication and Society}, journal = {Mass Communication and Society}, publisher = {Informa}, issn = {1520-5436}, doi = {10.1080/15205436.2025.2461082}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-51020}, pages = {25}, year = {2025}, abstract = {The issue of migration is highly salient in public debates in many countries. Given this salience and the risk of political instrumentalization, often by actors from the far right, it is important for citizens to receive high-quality, differentiated information on the migration issue. This touches upon the question of media performance. While there is abundant research on the media portrayal of the migration issue, this research strand is, surprisingly, hardly linked to research on media performance. We establish this link and present an innovative, sophisticated framework for standardized content analyses on migration. It combines three standards of media performance that are key to deliberative democratic theories—viewpoint diversity, balance, and deliberativeness—and utilizes value frames and the sociological concept of idea elements to measure viewpoint diversity and balance. A first empirical test of our newly developed approach, taking Germany as a case, shows noticeable differences in the media performance of 11 outlets analyzed. This test proves the applicability of our framework, which provides a valuable starting point for future comparative research on the media performance of migration coverage across countries and over time.}, subject = {Meinungsvielfalt}, language = {en} } @inproceedings{WeberFischerVogeletal.2013, author = {Weber, Konradin and Fischer, Christian and Vogel, Andreas and Pohl, Tobias and B{\"o}hlke, Christoph and Lau, Hendrik and Eliasson, Jonas and Palsson, Thorgeir}, title = {First results of an airborne release of volcanic ash for testing of volcanic ash plume measurement instruments}, series = {Recent Advances in Energy and Environmental Management}, volume = {Energy, Environmental and Structural Engineering Series 13}, booktitle = {Recent Advances in Energy and Environmental Management}, editor = {Mladenov, Valeri and Tasho, Tashev and Hui, Wang and Ivan, Kralov and Sergey, Stankevich and Pelin, Yildiz and Jon, Burley}, publisher = {WSEAS}, pages = {169 -- 172}, year = {2013}, subject = {Vulkanasche}, language = {en} } @inproceedings{RopertzLampDouardetal.1997, author = {Ropertz, Alexander and Lamp, Torsten and Douard, Mathilde and Weber, Konradin and Gaertner, Andrea and Elbers, C. and Nitz, R.}, title = {Calibration of a high-resolution open-path FTIR spectrometer combined with an adjustable 100-m multipass cell}, series = {SPIE Proceedings, Remote Sensing of Vegetation and Water, and Standardization of Remote Sensing Methods}, volume = {3107}, booktitle = {SPIE Proceedings, Remote Sensing of Vegetation and Water, and Standardization of Remote Sensing Methods}, editor = {Cecchi, Giovanna and Lamp, Torsten and Reuter, Rainer and Weber, Konradin}, publisher = {SPIE}, issn = {0277-786X}, doi = {10.1117/12.274749}, pages = {137 -- 147}, year = {1997}, subject = {FT-IR-Spektroskopie}, language = {en} } @inproceedings{WeberEickel1997, author = {Weber, Konradin and Eickel, Karl-Heinz}, title = {Standardization of open-path FTIR measurements in Germany}, series = {SPIE Proceedings, Remote Sensing of Vegetation and Water, and Standardization of Remote Sensing Methods}, volume = {3107}, booktitle = {SPIE Proceedings, Remote Sensing of Vegetation and Water, and Standardization of Remote Sensing Methods}, editor = {Cecchi, Giovanna and Lamp, Torsten and Reuter, Rainer and Weber, Konradin}, publisher = {SPIE}, issn = {0277-786X}, doi = {10.1117/12.274753}, pages = {174 -- 176}, year = {1997}, subject = {FT-IR-Spektroskopie}, language = {en} }
