Heinrich Best (Friedrich-Schiller-Universität Jena) und John Higley (University of Connecticut) haben mit dem knapp 700 Seiten umfassenden Handbuch eine bemerkenswerte Bestandsaufnahme der Forschung zu politischen Eliten vorgelegt. Beide Herausgeber haben sich über mehrere Jahrzehnte hinweg mit diesem Thema beschäftigt. Politische Eliten sind dabei nicht in einem engen Sinne ausschließlich als politische Entscheidungsträger zu verstehen, sondern werden weiter definiert als alle Personen, die Einfluss auf politische ...

Simple Summary The reasons for the development of diseases in the transition period of dairy cows are manifold and highly farm- and cow-specific. Nevertheless, links exist between the degree of negative energy balance (NEB) and disease susceptibility, which suggest a mutual adverse relationship between immune and productive functions. Glucose is the most essential fuel and precursor for both immune cells and mammary epithelial cells (MEC). While the delivery of glucose by the intermediary metabolism is not always ...

This paper applied a self-administered survey to investigate the impact of organic food behavior and the intention-behavior gap in organic food consumption (OIBG) on consumers’ subjective wellbeing including physical, emotional, social and intellectual dimensions. The survey was carried out with 385 consumers. Furthermore, the study conducted a food test to explore the different impacts of organic and conventional food samples on the mental and physical conditions of consumers’ wellbeing applying a psychological ...

Häufig werden im Mathematikunterricht Lerninhalte eher separiert behandelt. Der Ansatz des sogenannten verschachtelten Lernens geht dagegen davon aus, dass es in vielen Fällen sinnvoll ist, die Lerninhalte abwechselnd und vermischt anzuordnen, um bei den Schülerinnen und Schülern lern- und verstehensförderliche Prozesse anzuregen sowie nachhaltiges Lernen zu fördern. Verschachteltes Lernen zählt zu den wünschenswerten Erschwernissen. Das Ziel der wünschenswerten Erschwernisse ist, durch eine Erhöhung des kognitiven ...

Die Arbeit in Industrieunternehmen verändert sich auf Grund der Digitalisierung grundlegend. Entwicklungen in der Automatisierungstechnik können in naher Zukunft einen Teil der Arbeit von Arbeitnehmenden ersetzen. Dadurch wird es notwendig sein, sich auf die sich schnell wechselnden Qualifikationsanforderungen aus diesem Digitalisierungsprozess einzustellen. Hierzu gehört einerseits die schnelle Reaktionsfähigkeit auf die fortlaufenden Veränderungen, die in Unternehmen stattfinden, beispielsweise die Einbettung neuer ...

With the overlap of the interfirm relationship quality and supply chain management research in mind, this paper reviewed 100 recent, scientific, English-language papers on interfirm relationship quality based on a categorisation schema derived from a conceptual framework of supply chain management. We aim to contribute to the existing supply chain management literature by providing an insight into the connections of supply chain performance with buyer–supplier relationship quality from the relationship quality scholars’ ...

In the present investigation, thin sheets of stabilized and unstabilized ferritic stainless steel were welded in butt joint configuration using irradiation of a 1070 nm fiber-laser. Using optical microscopy, the microstructural evolution upon alternating heat input was characterized. In addition to that, hardness and tensile tests were carried out on the specimens. Detailed focus was given to the intergranular corrosion properties, which were investigated on basis of the Strauss test with different times of exposure ...

In this experiment, the effect of the alignment of leader behaviors with innovation requirements was investigated. A sample of N = 245 students participated in a laboratory experiment. Participants had to address either creativity or implementation requirements within a task and received a leadership manipulation in a video message. Results showed that the alignment of leader behaviors with innovation requirements led to improved performance. These findings contribute to the literature by addressing the specific ...

Municipal solid waste incineration (MSWI) is a major element of modern waste management and produces annually around 5.7 million tonnes of bottom ash (BA) in Germany. In order to save natural resources and protect the environment, utilisable materials need to be recovered from BA. It was the aim of the present study to determine metal and mineral resource potentials of MSWI BA based on a characterisation study of raw and aged BA of the MSWI plant in Kassel (Germany). The BA investigated consisted of 82.2% mineral ...

Since the Syrian crisis and the so-called “Arab Spring”, new discourses have been created, sparking the discursive water governance debates around water scarcity and hydropolitics. In Lebanon and Jordan—where most water resources are transboundary, and where most Syrian refugees have flown in—new discourses of climate change and especially of Syrian refugees as exacerbating water scarcity are emerging, shaping water governance debates. The aim of this paper is to engage in comparative discourse analysis about narratives ...
