Konfliktmanagement von interpersonellen und Intragruppenkonflikten in virtuellen Sitzungsformaten – Eine explorative Studie
(2022-12-05)
Die Bildung virtueller Teams nimmt durch die Digitalisierung, Internationalisierung sowie die pandemische Lage stetig zu. Dies bringt viele Vorteile, aber auch ein gesteigertes Konfliktpotenzial mit sich. Folglich gewinnen Konfliktmanagementstrategien für virtuelle Sitzungsformate zunehmend an Relevanz. Im Folgenden wird ein praxisrelevanter Handlungsleitfaden für virtuelles Konfliktmanagement dargelegt. Dabei wird deutlich, dass es von besonderer Bedeutung ist, eine realitätsnahe Begegnungssituation durch Videokonferenzen, ...

Metastable CrMnNi steels processed by laser powder bed fusion: experimental assessment of elementary mechanisms contributing to microstructure, properties and residual stress
(2022-12-18)
The complex thermal history imposed by the laser-based powder bed fusion of metals (PBF-LB/M) process is known to promote the evolution of unique microstructures. In the present study, metastable CrMnNi steels with different nickel contents and, thus, different phase stabilities are manufactured by PBF-LB/M. Results clearly reveal that an adequate choice of materials will allow to tailor mechanical properties as well as residual stress states in the as-built material to eventually redundantize any thermal post-treatment. ...

Three‑dimensional close‑to‑substrate trajectories of magnetic microparticles in dynamically changing magnetic field landscapes
(2022-12-03)
The transport of magnetic particles (MPs) by dynamic magnetic field landscapes (MFLs) using magnetically patterned substrates is promising for the development of Lab‑on‑a‑chip (LOC) systems. The inherent close‑to‑substrate MP motion is sensitive to changing particle–substrate interactions. Thus, the detection of a modified particle–substrate separation distance caused by surface binding of an analyte is expected to be a promising probe in analytics and diagnostics. Here, we present an essential prerequisite for such ...

Fabrication of High-Quality Thin Single-Crystal Diamond Membranes with Low Surface Roughness
(2022-10-17)
Certain aspects before and during the fabrication of single-crystal diamond (SCD) membranes are highlighted, which are decisive to obtain high-quality membranes with low surface roughness values around 0.2 nm on a small area scale. In addition to the requirements for the starting material, including a high planarity and a moderate surface roughness, the importance of cleaning processes to minimize particles and impurities before and during the structuring is emphasized. With the help of a planarization procedure, ...

Das Beurteilen von Lernprodukten als Facette diagnostischer Kompetenz fördern
(2022-12-02)
Diagnostische Kompetenz ist eine zentrale Komponente der professionellen Kompetenzen von Lehrkräften, die die Qualität von Unterricht und somit das Lernen von Schülerinnen und Schülern beeinflusst. Aufgrund dieser zentralen Bedeutung rückt die systematische Schulung der diagnostischen Kompetenz zunehmend in den Forschungsfokus. Diese Arbeit zielt auf die Erforschung der Förderung diagnostischer Kompetenz im Bereich der Mathematik ab. Wir stellen eine quasi-experimentelle Studie mit Treatment- und Kontrollgruppe vor, ...

The role of design patterns in the development and legal assessment of lawful technologies
(2022-10-22)
Novel technologies such as smart personal assistants integrate digital services into everyday life. These services use personal data to offer personalized services. While they are subject to special data protection regulations at the time of development, there are few guidelines describing the transition from legal requirements to implementation. To reduce risks, services depend on external legal assessments. With developers and legal experts often missing either legal or technical knowledge, the challenge lies in ...

Exploring the associations between psychodynamic constructs and psychopathology: A network approach
(2022-07-25)
Psychodynamic therapy effectively reduces symptomatology by focusing on underlying (unconscious) processes instead of symptoms. Nevertheless, the exact interrelationship between psychodynamic constructs and psychopathology remains unclear. This study uses network analysis to explore these associations. We computed a cross-sectional partial correlation network between psychodynamic constructs (i.e., personality functioning, interpersonal relations, and active and passive modes of intrapsychic conflicts according to ...

Sustainability performance measurement in risk and uncertainty management: An analysis of base of the pyramid supply chain literature
(2022-10-10)
Risk management in the base of the pyramid (BoP) environment is needed to ensure that firms performance objectives are met. Accordingly, integrating sustainability performance measurement in the supply chain risk management would offer interesting avenues for managing risks in BoP supply chain. Therefore, the paper conceptualizes an intersection between supply chain risk/uncertainty management and sustainable performance measurement. This intersection is then tested by a literature review of 164 BoP SC articles between ...

Research topic flows in co-authorship networks
(2022-10-11)
In scientometrics, scientific collaboration is often analyzed by means of co-authorships. An aspect which is often overlooked and more difficult to quantify is the flow of expertise between authors from different research topics, which is an important part of scientific progress. With the Topic Flow Network (TFN) we propose a graph structure for the analysis of research topic flows between scientific authors and their respective research fields. Based on a multi-graph and a topic model, our proposed network structure ...

Microstructural and mechanical properties of AlSi10Mg: Hybrid welding of additively manufactured and cast parts
(2022-12-07)
Welding and joining of hybrid components consisting of additively manufactured (AM) parts and conventionally processed parts offer new opportunities in structural design. In the present study, AlSi10Mg specimens were fabricated using two different manufacturing processes, i.e., laser-based powder-bed fusion of metals (PBF-LB/M) and casting, and welded by means of friction stir welding (FSW). Material strength of dissimilar welded joints was found to be governed by the as-cast material, which is characterized by a ...
