Housing in Germany and the Rebirth of the High‐Rise in Post‐Modern Urban Design
(2022-11-22)
High-rise buildings were a frequent design element in modernist urban planning and architecture. However, both the criticisms modernism faced and the negative experiences with large housing estates dating from that period led to post-modern designs that built strongly on traditional pre-modernist urban form. Despite the role of high-rise buildings in office areas, many brownfield and greenfield housing developments from the 1980s to the 2000s reflected this trend and abandoned high-rise buildings almost completely ...

Spatially explicit life cycle assessments reveal hotspots of environmental impacts from renewable electricity generation
(2022-08-30)
Renewable energy generation has great potential to reduce greenhouse gas emissions, however, it may exacerbate other environmental impacts, such as water scarcity, elsewhere in the supply chain. Here, we reveal a wide range of global environmental impacts of concentrated solar power, run-of-river hydropower, and biomass burning compared to classical coal-fired power: Spatially explicit life cycle impact assessment is used to evaluate their supply chains with respect to demand for energy, land, material, and water, ...

Development of an Optical System Based on Spectral Imaging Used for a Slug Control Robot
(2022-01-14)
The state-of-the-art technique to control slug pests in agriculture is the spreading of slug pellets. This method has some downsides, because slug pellets also harm beneficials and often fail because their efficiency depends on the prevailing weather conditions. This study is part of a research project which is developing a pest control robot to monitor the field, detect slugs, and eliminate them. Robots represent a promising alternative to slug pellets. They work independent of weather conditions and can distinguish ...

Agile Erzählungen
(2022-01-05)
Wenn man sich mit dem Thema „Agilität“ inhaltlich befasst, erscheint es nicht angeraten, es in erster Linie als ein einheitliches theoretisches Konstrukt oder Modell zu betrachten, das man auf seine interne logische Stimmigkeit seiner einzelnen Bestandteile und auf deren empirische Verankerung hin überprüft. Damit würde man Kriterien anlegen, bei denen von vorneherein offensichtlich ist, dass der agile Ansatz dem weder gerecht werden kann noch will. Die eigentliche Bedeutung des agilen Konzepts liegt nicht in seiner ...

A study of 25 years of publication outputs in the German academic profession
(2022-01-11)
In the weak evaluation state of Germany, full professors are involved in the traditional social governance partnership between the state, and the self-governing higher education institutions (HEI) and disciplinary associations. Literature suggests that formal and informal governance could trigger changes in academics’ publication behavior by valorizing certain publication outputs. In the article, secondary data from three surveys (1992, 2007 and 2018) is used for a multi-level study of the evolution of academics’ ...

A Critical Review on the Complex Potentials in Linear Elastic Fracture Mechanics
(2022-01-03)
Introducing a crack in an elastic plate is challenging from the mathematical point of view and relevant within an engineering context of evaluating strength and reliability of structures. Accordingly, a multitude of associated works is available to date, emanating from both applied mathematics and mechanics communities. Although considering the same problem, the given complex potentials prove to be different, revealing various inconsistencies in terms of resulting stresses and displacements. Essential information on ...

Using New Spare Parts for Repair of Waste Electrical and Electronic Equipment? The Material Footprint of Individual Components
(2022-02-21)
The growing production of waste electrical and electronic equipment (WEEE) requires close loop management to protect the environment and save resources. Repair and reuse can extend the product’s life span. However, debates on the differences seen in resource consumption linked to the different ways of repairing devices have received a limited amount of attention. This article demonstrates quantification of the resource consumption (cradle-to-gate) of five types of appliances on a component level based on life-cycle ...

Rechte Radikalisierung und Deradikalisierung – Perspektiven in der psychologischen Beratung. Zum Film „Skin“ von Guy Nattiv
(2022-01-10)
Vor dem Hintergrund des Films „Skin“ von Guy Nattiv (2018) wird ein Einblick in die Dynamiken von Radikalisierungsprozessen gegeben unter Einbeziehung einer multifaktoriellen Perspektive. In einem zweiten Schwerpunkt werden die Gelingens- und Rahmenbedingungen von Deradikalisierungsprozessen erörtert. Der Beitrag schließt mit der Darstellung eines Beratungsansatzes zur Deradikalisierung.

Barriers in Participative Water Governance: A Critical Analysis of Community Development Approaches
(2022-02-28)
Participatory approaches within development programs involving common-pool resources are intended to revive a community’s role in managing these resources. Certainly, to ensure the successful and equitable use of such resources, community participation is essential. However, in many cases, attempts at applying a participatory approach often fail to genuinely engage all subgroups within a community due to assumptions of homogeneity and a lack of understanding of the deep socio-political divisions between people. As a ...

Modelling and Simulation of Building Material Flows: Assessing the Potential for Concrete Recycling in the German Construction Sector
(2022-03-01)
The reuse and recycling of materials can make an important contribution to the conservation of natural resources in the sense of a circular economy. This applies in particular to high quality recycling, supporting the material use of waste and closing product cycles. The construction sector is the most important sector in terms of available volume of materials for recycling. However, the largest share of recycling (RC) materials goes predominantly into road construction and underground engineering. This research ...
