Imagined publics - On the structural transformation of higher education and science. A post-Habermas perspective
(2023-10-03)
Referring to Habermas’ groundbreaking book ‘The structural transformation of the public sphere’, the article discusses contemporary transformations of higher education and science. In order to do so, in a first step a post-Habermas perspective will be developed, which implies two changes to the theoretical foundations guiding Habermas’ analysis: On the one hand, we are in the midst of a social transformation that has led to a pluralization of the understandings of the public – that is, publics. The representation of ...

Challenge Not Only to the Muscles - Surface Instability Shifts Attentional Demands in Young and Older Adults While Performing Resistance Exercise
(2023-11-28)
Regular physical activity is an important factor in maintaining and improving physical and cognitive functions in an aging society. Compared to resistance and endurance training, motor tasks with attentional demands and cognitive activation are considered to have a greater potential for improving executive functions. Unstable devices increase the coordinative demands and could thus lead to increased cognitive engagement during acute resistance exercises. This study aimed to investigate the required attentional resources ...

Spectres of European money and Stefan Eich’s Currency of Politics
(2024-01-10)
This paper aims at discussing the historical trajectory of European money and the way it can be illuminated through a dialogue with Stefan Eich’s The Currency of Politics. Fleshing out the different theories, visions, and conceptualisations of money in Eich’s book, this paper utilises this exposition to evaluate the development and operationalisation of European money. With an eye to contemporary debates about the re-politicisation or democratisation of money, the paper will critically assess the way in which Eich’s ...

Legal Struggles: A Social Theory Perspective on Strategic Litigation and Legal Mobilisation
(2023-03-08)
Social movements, NGOs and other political actors often mobilise the law for social change. Strategic litigation and collective legal mobilisation can be key instruments to face current political challenges like the climate crisis, human rights violations against refugees or the exploitation of workers along global supply chains. Although these struggles are framed by a societal context and have impacts on the political and juridical fields, the literature about legal mobilisation still does not decidedly engage with ...

Research and development intensive clusters and regional competitiveness
(2023-05-02)
Modern cluster theory provides reasons for positive external effects that accrue from the interaction of spatially proximate firms operating in common and related fields of economic activity. In this paper, we examine the impact of R&D-intensive clusters as a key factor of regional competitiveness on productivity growth. In relying on a hybrid approach of cluster identification, we examine effects of cluster specialization and diversity for a panel of German NUTS-3 regions in 2003–2019. After controlling for regional ...

Health promotion for the unemployed: the evaluation of the JOBS Program Germany from the trainers’ perspective
(2023-11-17)
Background
The JOBS Program Germany is a labor market integrative and health promotion intervention for unemployed people. This study examines JOBS Program Germany trainers’ view of (1) the theoretical concept of the JOBS Program, (2) its practical implementation in Germany on-site, (3) its acceptance by participants, and (4) the training effects. The study aimed at identifying potential for adaption allowing adjustments to improve the practical implementation and the training effectiveness.
Methods
JOBS Program ...

Analysis of the Machine-Specific Behavior of Injection Molding Machines
(2023-12-22)
The performance of an injection molding machine (IMM) influences the process and the quality of the parts manufactured. Despite increasing data collection capabilities, their machine-specific behavior has not been extensively studied. To close corresponding research gaps, the machine-specific behavior of two hydraulic IMMs of different sizes and one electric IMM were compared with each other as part of the investigations. Both the start-up behavior from the cold state and the behavior of the machine at different ...

Cover crops and compost prevent weed seed bank buildup in herbicide‐free wheat-potato rotations under conservation tillage
(2019-02-07)
Weeds are a major constraint affecting crop yields in organic farming and weed seed bank analysis can be an important tool for predicting weed infestation and assessing farming system sustainability.
We compared the weed seed banks two and four years after transition from conventional to reduced tillage in organically managed winter wheat–potato cropping sequences in two replicated field trials. Experimental factors were either conventional (CT) with moldboard (25 cm) or reduced tillage (RT) with chisel ploughing ...

Influence of effluent particles and particle-bound micropollutants on the removal of micropollutants and UVA₂₅₄ in wastewater effluent ozonation
(2024-01-09)
This study systematically investigated the influence of effluent particles and activated sludge (AS) particles on the removal of micropollutants via wastewater effluent ozonation within typical effluent total suspended solids (TSS) concentrations. A series of batch experiments revealed that particle concentrations up to 30 mg/L had a minor impact on the removal of organic micropollutants (OMPs) in the aqueous phase. Moreover, the reduction of UV absorbance at 254 nm (UVA₂₅₄) was negatively correlated to the level of ...

Exploring the evolutionary dynamics of myrmecophytism: Perspectives from the Southeast Asian Macaranga ant-plant symbiosis
(2024-02-09)
Myrmecophytic plants utilise defensive services offered by obligate ant partners nesting in their domatia in a novel means of survival in tropical habitats. Although much is known about the ecology of myrmecophytism, there aren’t enough empirical examples to demonstrate whether it substantially influences evolutionary patterns in host plant lineages. In this study, we make use of the species-rich Macaranga (Euphorbiaceae) ant-plant symbiosis distributed in the Southeast Asian Sundaland to delve into the evolutionary ...
