Development of a Passenger Assistance System to Increase the Attractiveness of Local Public Transport
(2022-03-22)
In this paper, we present a concept for an assistance system for public transport passengers currently being developed for Kassel, Germany, and its surrounding area. The assistance system aims at increasing the attractiveness of local public transport by reducing barriers to use, thus promoting sustainable travel behavior. Three main barriers were identified: crowded vehicles, missed connections, and inconveniences in the transportation of shopping bags and luggage. To tackle these issues, three assistance system ...

Method and experimental investigation of surface heat dissipation measurement using 3D thermography
(2022-02-11)
Three-dimensional thermography describes the fusion of geometry- and temperature-related sensor data. In the resulting 3D thermogram, thermal and spatial information of the measured object is available in one single model. Besides the simplified visualization of measurement results, the question arises how the additional data can be used to get further information. In this work, the Supplement information is used to calculate the surface heat dissipation caused by thermal radiation and natural convection. For this ...

Pathologies of a Different Kind: Dysfunctional Interactions between International Organizations
(2022-01-17)
This article develops the concept of “interorganizational pathologies” as an extension of Michael N. Barnett and Martha Finnemore's work on bureaucratic pathologies. Adopting an open system perspective, I argue that dysfunctional interactions may arise between international organizations (IOs) even when their cooperation is fairly institutionalized. To advance this line of reasoning, I examine interactions between the International Monetary Fund (IMF or Fund) and the World Bank (or Bank). Evidence from more than ...

Who wants to learn harder? The relationship between conservatism and liberalism, desirable difficulties, and academic learning
(2022-01-04)
Previous work has shown that challenging learning strategies like desirable difficulties improve long-term learning. Nonetheless, because they might be regarded as strict and demanding learning strategies, they should not be perceived as positive by everyone. They should, however, fit conservative political attitudes since those are, among others, positively correlated with individuals’ need for order and structure as well as with challenging learning environments. Hence, we hypothesized conservative political attitudes ...

Bonding Behaviour of Steel Fibres in UHPFRC Based on Alkali-Activated Slag
(2022-03-04)
The mechanical performance of fibre-reinforced ultra-high-performance concrete based on alkali-activated slag was investigated, concentrating on the use of steel fibres. The flexural strength is slightly higher compared to the UHPC based on Ordinary Portland Cement (OPC) as the binder. Correlating the flexural strength test with multiple fibre-pullout tests, an increase in the bonding behaviour at the interfacial-transition zone of the AAM-UHPC was found compared to the OPC-UHPC. Microstructural investigations on the ...

Dissolution of Portlandite in Pure Water: Part 1 Molecular Dynamics (MD) Approach
(2022-02-14)
The current contribution proposes a multi-scale bridging modeling approach for the dissolution of crystals to connect the atomistic scale to the (sub-) micro-scale. This is demonstrated in the example of dissolution of portlandite, as a relatively simple benchmarking example for cementitious materials. Moreover, dissolution kinetics is also important for other industrial processes, e.g., acid gas absorption and pH control. In this work, the biased molecular dynamics (metadynamics) coupled with reactive force field ...

Transmission Electron Microscopy Study on the Precipitation Behaviors of Laser-Welded Ferritic Stainless Steels and Their Implications on Intergranular Corrosion Resistance
(2022-01-04)
The intergranular corrosion susceptibility of ferritic stainless-steel weldments is strongly dependent on chromium carbide precipitation phenomena. Hence, stabilization is widely used to mitigate the aforementioned precipitation. In contrast, stabilization has proved ineffective to fully prevent intergranular corrosion due to segregation of unreacted chromium during solid-state heat-treatments. To analyze the precipitation behavior of 17 wt.-% chromium ferritic stainless steels during laser welding, sheets of ...

Welchen Herausforderungen begegnen Kreativdirektor/innen in Werbeagenturen? Exploration einer neuen Zielgruppe für Beratung
(2022-03-18)
Obwohl creative leadership zu den buzzwords der letzten Jahre gehörte, sind Kreativdirektor/innen in Werbeagenturen von der Wissenschaft in Deutschland bislang unbeachtet geblieben. Die vorliegende qualitative Untersuchung hat im Rahmen von sechs Interviews mit Kreativdirektor/innen analysiert, welchen Herausforderungen diese Zielgruppe in ihrem Berufsalltag begegnen. Das Ergebnis der Untersuchung zeigt, dass neben der Vereinbarung von kreativem Arbeiten mit Führungsaufgaben neue Organisationsformen, der digitale ...

Weinen im Coaching – oder: Gehört der Taschentuchspender in jede Coachingpraxis?
(2022-03-30)
Das Weinen als fundamentaler menschlicher Emotionsausdruck wirft innerhalb verschiedener Fachdisziplinen seit jeher Fragen auf. In den letzten Jahren lässt sich auch innerhalb der klinischen Forschung eine zunehmende Beschäftigung mit diesem Thema beobachten. U. a. konnte im Rahmen einer Untersuchung an der Universität Kassel eine Systematisierung über verschiedene Formen des Weinens in der Psychotherapie und unterschiedliche therapeutische Verhaltensweisen im Umgang damit entwickelt werden. Im vorliegenden Artikel ...

Harnessing the Potential of Wheat-Pea Species Mixtures: Evaluation of Multifunctional Performance and Wheat Diversity
(2022-03-25)
Species mixtures and heterogeneous crop populations are two promising approaches for diversified ecological cropping systems with increased resilience and reduced dependency on external inputs. Inter- and intraspecific diversity were evaluated in combination using 15 wheat (Triticum aestivum) entries, including line cultivars and heterogeneous populations (HPs), from central Europe and Hungary and one winter pea cultivar under organic conditions. Monocultures and wheat mixtures were evaluated multi-functionally for ...
