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 highest SO2 concentration at the source was nearly up to 100 mg/m3.

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 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} } @article{GeneralBobrowskiPoehleretal.2015, author = {General, S. and Bobrowski, N. and P{\"o}hler, D. and Weber, Konradin and Fischer, C. and Platt, U.}, title = {Airborne I-DOAS measurements at Mt.

The rate at which sulphur dioxide oxidises to sulphate aerosol is poorly constrained and measurements of downwind abundance are required to quantify the rate at which this process occurs. During July and November 2011, a series of measurements were performed in emissions from Etna Volcano, Sicily, using the University of Applied Sciences (Dusseldorf) research aircraft. Both in situ and remote sensing instrumentation was simultaneously deployed to quantify the down-wind characteristics of gases and particles in the plume emitted by the volcano. In situ particle characteristics were measured using a Grimm 1.109 optical particle counter (microparticles 0.25-32 microns) and Grimm 1320 diffusion electrometer (nanoparticles 25-300 nanometers). Column abundance of sulphur dioxide was measured using a vertically-pointing differential optical absorption spectrometer (DOAS). These measurements were compared to horizontal pathlength-integrated measurements of sulphur dioxide from the Airborne Volcanic Imaging Object Detector (AVOID). Down-wind plume dispersion was discriminated through a series of aircraft transects below and through the volcanic plume. The emissions contained large amounts of nanoparticles relative to microparticles, which reflects gas-phase nucleation of sulphate aerosol. The AVOID system discriminated horizontal layering of volcanic aerosol at altitudes of up to 12,000 ft from a detection range of >50 km. Plume boundaries were discriminated using a combination of the in situ and DOAS measurements in order to compare to the pathlength-integrated measurements from AVOID.}, subject = {Forschungsflugzeug}, language = {en} } @inproceedings{DeckertMohya2023, author = {Deckert, Carsten and Mohya, Ahmed}, title = {Tinkering, Tools and Techniques - Creativity in German Engineering Education}, series = {AIJR Proceedings: Proceedings of the 14th European Conference on Creativity in Innovation}, booktitle = {AIJR Proceedings: Proceedings of the 14th European Conference on Creativity in Innovation}, editor = {Heijne, Katrina}, publisher = {AIJR Publisher}, issn = {2582-3922}, doi = {10.21467/proceedings.154.2}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-51142}, pages = {11 -- 18}, year = {2023}, abstract = {Purpose - Engineers are expected to be the creative problem solvers and innovative tinkerers of a company. This article examines to what extent German tertiary education lives up to this expectation. The analysis of German module descriptions in engineering shows that there are no courses dedicated to creativity and that creativity and its techniques are mentioned only sparsely in the modules of the engineering curriculum. Surveys amongst our students show that they are usually familiar with techniques which are based on generating alternatives such as brainstorming and morphological box, but lack knowledge about techniques based on challenging assumptions such as forced connection. They tend to favour discursive techniques over intuitive ones and techniques which use generation of alternatives as an idea-generating principle. A combination of creativity techniques seems to be most conducive to creative output in our course. Finally, we present some first findings on creative sessions in remote work with the help of virtual whiteboards, which have gained in importance since the pandemic. Methodology - Firstly, we present an document analysis of the modules of Bachelor and Master programs of mechanical engineering at German universities and universities of applied sciences. Secondly, we present results from surveys in our Master course in "Innovation and Technology Management" where we gathered data from students over several years and performed an external evaluation of the output using Consensual Assessment Technique (CAT). These results include which creativity techniques the students know prior to the course and which they prefer as well as which techniques seem to be conducive to engineering creativity. Furthermore we surveyed their experiences with creative sessions as remote work. Conclusion - Overall, the article shows the importance to teach prospective engineers the basics in creativity. Students should have the opportunity to acquire knowledge about and apply different creativity techniques, as different techniques have different strengths and weaknesses and, thus, different areas of fruitful application. They should also have the chance to try out different modes such as in-person sessions and virtual sessions, as some of the future work will most likely shift online. Furthermore, a combination of different creativity techniques makes it more likely that engineers break through their usual systematic-analytic way of thinking and helps them to think outside the box to find creative solutions for the pressing problems of our time.}, subject = {Ingenieurstudium}, language = {en} } @incollection{Deckert2023, author = {Deckert, Carsten}, title = {Sustainable Logistics}, series = {Encyclopedia of Sustainable Management}, booktitle = {Encyclopedia of Sustainable Management}, publisher = {Springer Nature}, address = {Cham}, isbn = {9783031259838}, doi = {10.1007/978-3-031-25984-5_131}, pages = {3562 -- 3566}, year = {2023}, language = {en} } @incollection{Deckert2023, author = {Deckert, Carsten}, title = {Supply Chain}, series = {Encyclopedia of Sustainable Management}, booktitle = {Encyclopedia of Sustainable Management}, publisher = {Springer Nature}, address = {Cham}, isbn = {9783031259838}, doi = {10.1007/978-3-031-25984-5_132}, pages = {3212 -- 3214}, year = {2023}, language = {en} } @inproceedings{DeckertMohya2023, author = {Deckert, Carsten and Mohya, Ahmed}, title = {Teaching Sustainable Logistics As A Project-Based Learning Course}, series = {European Society for Engineering Education (SEFI), 11-14 September 2023, TUDublin, Ireland}, booktitle = {European Society for Engineering Education (SEFI), 11-14 September 2023, TUDublin, Ireland}, publisher = {TU Dublin}, address = {Dublin}, doi = {10.21427/9D3F-KA64}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-51182}, year = {2023}, abstract = {Sustainable logistics combines the task of the 6R of logistics (right product, right place, right time, right condition, right cost) with social and environmental sustainability, especially low emissions and low resource consumption. This means that a problem that is already challenging, namely planning, executing, and controlling logistical processes, gets even more complex and requires aspects of systems thinking to incorporate environmental and social impacts. Classical approaches of teaching, e.g. lectures with presentations and short exercises on closed problems, do not do justice to the complexity and intricacies of the topic sustainability. In such a context, projectbased learning (PBL) where students do group work on open-ended problems with real-world complexity seems to be a more adequate means to teach the subject. The paper describes a PBL course in which students worked on projects to conceptualize micro-depots for parcel delivery in different areas of D{\"u}sseldorf. A micro-depot is a temporary storage location in a city from which parcels can be delivered by cargo bikes. The aim was to locate the micro-depot, design the delivery routes, check the feasibility, and calculate the reduction of greenhouse gases and other emissions. The course was taught in cooperation with a partner from the courier, express, and parcel delivery industry.
