Der innerpsychische Konflikt Individuation vs. Abhängigkeit im Coaching: Zentrale Ergebnisse einer qualitativen Studie zur Praxis erfahrener Coaches
(2021-11-09)
Die unbewusste Dynamik von innerpsychischen Konflikten ist ein wichtiger Inhalt des Erlebens und Verhaltens von Menschen und hat vermutlich einen Einfluss in Coachingprozessen. Diese Studie fokussiert den Grundkonflikt „Individuation vs. Abhängigkeit“ in Einzelcoachings. In einer kleinen qualitativen Feldstudie (n = 13) wurden erfahrene Coaching-Expert/innen zu subjektiven Theorien und präferierten Arbeitskonzepten im Handling dieses Konflikts im Einzelcoaching befragt. Die Inhaltsanalyse zeigt Strategien zum Handling ...

1,1′-Ferrocenylene-Bridged Bis(N-Heterocyclic Olefin) Derivatives
(2021-10-18)
The 1,1′-ferrocenylene (fc)-bridged bis(N-heterocyclic olefin) compounds (IMes=CH)₂fc (1, IMes=1,3-dimesitylimidazolin-2-ylidene) and (IPr=CH)₂fc (2, IPr=1,3-bis(2,6-diisopropylphenyl)imidazolin-2-ylidene) were synthesised from (ICH₂)₂fc (3) and the respective N-heterocyclic carbene IMes or IPr. Ligand substitution reactions of 1 and 2 with [BH₃(THF)] afforded the complexes [1(BH₃)₂] and [2(BH₃)₂] as mixtures of the rac- and meso-diastereomers. The new ferrocene derivatives 1–3 and the complexes meso-[1(BH₃)₂], ...

A Novel Real Time PCR Method for the Detection and Quantification of Didymella pinodella in Symptomatic and Asymptomatic Plant Hosts
(2021-12-31)
Didymella pinodella is the major pathogen of the pea root rot complex in Europe. This wide host range pathogen often asymptomatically colonizes its hosts, making the control strategies challenging. We developed a real-time PCR assay for the detection and quantification of D. pinodella based on the TEF-1 alpha gene sequence alignments. The assay was tested for specificity on a 54-isolate panel representing 35 fungal species and further validated in symptomatic and asymptomatic pea and wheat roots from greenhouse tests. ...

Agilität – ein Organisationsmodell für öffentliche Verwaltungen
(2021-07-07)
Dieser Artikel zeigt auf, weshalb das Organisationsmodell Agilität als Reformkonzept für öffentliche Verwaltungen geeignet ist und einen wesentlichen Beitrag zu den noch offenen Themen aus bisherigen Reformen leisten kann. Dies wird entlang den Dimensionen Legitimation (Strategie), Governance (Struktur und Prozesse), Digitalisierung (Technik) und Führung begründet. Führungskräften in öffentlichen Verwaltungen kommt eine zentrale Schlüsselrolle bei den anstehenden Reformen zu. Das Führungsset „Agile Five“, das eine ...

Identification of a Spatio-Temporal Temperature Model for Laser Metal Deposition
(2021-12-18)
Laser-based additive manufacturing enables the production of complex geometries via layer-wise cladding. Laser metal deposition (LMD) uses a scanning laser source to fuse in situ deposited metal powder layer by layer. However, due to the excessive number of influential factors in the physical transformation of the metal powder and the highly dynamic temperature fields caused by the melt pool dynamics and phase transitions, the quality and repeatability of parts built by this process is still challenging. In order to ...

Strategic framing of genome editing in agriculture: an analysis of the debate in Germany in the run-up to the European Court of Justice ruling
(2021-10-09)
New techniques in genome editing have led to a controversial debate about the opportunities and uncertainties they present for agricultural food production and consumption. In July 2018, the Court of Justice of the European Union defined genome editing as a new process of mutagenesis, which implies that the resulting organisms count as genetically modified and are subject, in principle, to the obligations of EU Directive 2001/18/EG. This paper examines how key protagonists from academia, politics, and the economy ...

Das Potenzial kooperativen Lernens ausschöpfen: Die Bedeutung der transaktiven Kommunikation für eine lernwirksame Zusammenarbeit
(2021-10-26)
Kooperatives Lernen eröffnet Chancen und birgt gleichzeitig Risiken für den Wissenserwerb. Der Beitrag arbeitet die Bedeutung der transaktiven Kommunikation als zentralen Wirkmechanismus für den genuinen Mehrwert kooperativen Lernens heraus. Unter transaktiver Kommunikation wird die fachinhaltliche Bezugnahme auf den Lernpartner verstanden, wobei niedrig-transaktive (z.B. paraphrasierende) von hoch-transaktiven (z.B. integrierenden) Äußerungen unterschieden werden. Es werden Bedingungen, unter denen sich transaktive ...

The financialization of remittances and the individualization of development: A new power geometry of global development
(2021-08-23)
The article argues that the increasing financialization of remittances produces an enormous shift in the political economy of development and contributes to a new power geometry of development. Exploring this power geometry, the article focuses on three main issues: First, migrants intend to support their friends and families on an individual level as remittance senders, and together with the corresponding recipients they form a translocal moral economy. On a macro level, the value of these transactions is high when ...

Adsorption of PCE in alkali-activated materials analysed by fluorescence microscopy
(2021-10-18)
The realisation of high-performance concrete mixtures requires the use of superplasticizers to achieve a low water/binder ratio and thus high strengths. Polycarboxylate ethers (PCE) are mostly used as superplasticizers. The effectiveness of these superplasticizers depends on their chemical structure, the binders’ alkaline environment and the ions present in the pore solution of the binder. In high alkaline systems like some alkali-activated materials no effective superplasticizer have been found yet. To unravel the ...

On Optimal Test Signal Design and Parameter Identification Schemes for Dynamic Takagi-Sugeno Fuzzy Models Using the Fisher Information Matrix
(2021-11-21)
This paper is concerned with the analysis of optimization procedures for optimal experiment design for locally affine Takagi-Sugeno (TS) fuzzy models based on the Fisher Information Matrix (FIM). The FIM is used to estimate the covariance matrix of a parameter estimate. It depends on the model parameters as well as the regression variables. Due to the dependency on the model parameters good initial models are required. Since the FIM is a matrix, a scalar measure of the FIM is optimized. Different measures and ...
