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 ...

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 ...

A material model for thick, rate-dependent adhesives with delocalized softening
(2023-10-04)
This contribution is dedicated to the development and implementation of a material model to describe the deformation behaviour of assembly adhesives. These assembly adhesives are usually used with thicknesses of several millimetres up to centimetres in order to compensate for large relative displacements of joining parts. These large displacements can be resisted by assembly adhesives, since they have a low shear modulus and thus a high strain until failur above their glass transition temperature. As a basis, the ...

Influence of Chitosan and Grape Seed Extract on Thermal and Mechanical Properties of PLA Blends
(2023-03-22)
Blends based on polylactic acid (PLA), chitosan, and grape seed extract (GE) were prepared by extrusion and injection molding. The effect of chitosan (5% and 15% on PLA basis) and natural extract (1% on PLA basis) incorporated into the PLA host matrix was explored regarding the thermal and mechanical properties. GE showed antioxidant activity, as determined by the DPPH assay method. Chitosan and GE affect the degree of crystallinity up to 30% as the polysaccharide acts as a nucleating agent, while the extract reduces ...
