Late to the Party—Transferred Mulch from Green Manures Delays Colorado Potato Beetle Infestation in Regenerative Potato Cropping Systems
(2022-12-12)
The Colorado potato beetle (CPB) is an exceptionally challenging potato pest. Some regenerative farmers have reported that the use of transferred green manure mulch can considerably reduce CBP damage. Previous studies confirm this observation, but mainly with straw mulch, which is rarely used in Central Europe, and not embedded in the new regenerative cropping approach. For this, six trials conducted between 2014 and 2019 were evaluated, comparing CPB infestation in potatoes with and without transferred mulch as well ...

Kultur, Soziale Arbeit und Kulturelle Bildung
(2022-12-06)
Der Beitrag erörtert nach historischen Vergewisserungen die Wechselbeziehungen und die Zusammenarbeit zwischen kulturellen und sozialen Gesellschaftsbereichen, der Kulturellen Bildung und der Sozialen Arbeit. Angesichts gesellschaftlicher Veränderungen wird davon ausgegangen, dass eine konturenscharfe Trennung zwischen dem Kulturellen und dem Sozialen nicht mehr durchgängig möglich ist.

Farming system effects on root rot pathogen complex and yield of faba bean (vicia faba) in Germany
(2022-12-21)
A survey across Germany was undertaken from 2016-2019 to evaluate effects of management system (organic vs conventional), pedo-climatic conditions and crop rotation history on faba bean root health status, diversity of major root rot pathogens and yield. Root rot incidence was generally low and there was no effect of the management system on the spectrum of pathogens isolated. Among the most common fungal species identified, frequencies of Fusarium redolens and Didymella pinodella were significantly higher in roots ...

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 ...

Transnationaler Bergbau und lokale Politik
(transcript, 2022)
Diese Arbeit stellt die Interaktionsbeziehungen zwischen Bergbauunternehmen, den politischen Vertreter:innen sowie Vertreter:innen weiterer Einrichtungen aus dem Bildungsbereich und lokaler Wirtschaftssektoren in den Gemeinden in den Abbauregionen industrieller Minen in den Fokus der Untersuchung.
Ziel der vorliegenden Arbeit ist es, das Handeln transnationaler Bergbauunternehmen in lokalen Politikarenen zu analysieren. Eine solche Untersuchung soll Erklärungsansätze dafür entwickeln, welche Strategien Bergbauunternehmen ...
