Reviewing interfirm relationship quality from a supply chain management perspective
(2020-09-23)
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’ ...

On the Intergranular Corrosion Properties of Thin Ferritic Stainless Steel Sheets Welded by Fiber-Laser
(2020-08-12)
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 ...

Aligning Leader Behaviors With Innovation Requirements Improves Performance: An Experimental Study
(2020-07-07)
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 ...

Grain-Size Specific Characterisation and Resource Potentials of Municipal Solid Waste Incineration (MSWI) Bottom Ash: A German Case Study
(2020-05-31)
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 ...

Syrian Refugees, Water Scarcity, and Dynamic Policies: How Do the New Refugee Discourses Impact Water Governance Debates in Lebanon and Jordan?
(2020-01-22)
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 ...

Impact of Process Parameters and Bulk Properties on Quality of Dried Hops
(2020-11-20)
Hops are critical to the brewing industry. In commercial hop drying, a large bulk of hops is dried in multistage kilns for several hours. This affects the drying behavior and alters the amount and chemical composition of the hop oils. To understand these changes, hops of the var. Hallertauer Tradition were dried in bulks of 15, 25 and 35 kg/m² at 60 °C and 0.35 m/s. Additionally, bulks of 25 kg/m² were also dried at 65 °C and 0.45 m/s to assess the effect of change in temperature and velocity, respectively. The results ...

Effects and Prerequisites of Self-Generation in Inquiry-Based Learning
(2020-10-10)
The goal of this study is to investigate the effect of self-generation in inquiry-based learning and to identify the role of feedback. While open-ended inquiry-based learning with a high degree of self-generation requirements has long been considered optimal for facilitating effective learning, its long-run effects have been critically challenged. This study employed a 3 (learning condition) × 2 (retention interval) mixed factorial design (N = 98). An inquiry activity involving the self-generation of content knowledge ...

Improving Vertical Wind Speed Extrapolation Using Short-Term Lidar Measurements
(2020-03-29)
This study investigates how short-term lidar measurements can be used in combination with a mast measurement to improve vertical extrapolation of wind speed. Several methods are developed and analyzed for their performance in estimating the mean wind speed, the wind speed distribution, and the energy yield of an idealized wind turbine at the target height of the extrapolation. These methods range from directly using the wind shear of the short-term measurement to a classification approach based on commonly available ...

Food and Nutrition-Related Knowledge, Attitudes, and Practices among Reproductive-age Women in Marginalized Areas in Sri Lanka
(2020-06-04)
Nutrient deficiencies are a public health problem in Sri Lanka. Achieving food security is a major challenge due to unhealthy eating patterns. The nutritional status of a woman and her knowledge is a powerful indicator of the nutritional security of her children and household food security. Nutrition-related knowledge and attitude are necessary for dietary changes towards a healthier dietary pattern. For that reason, food and nutrition-related Knowledge, Attitude and Practice (KAP) is one of the key factors to achieving ...

Wilde Urbaniten
(2020-04-24)
Die rechtlich-administrative und räumlich-planende Regulation des Vorkommens wildlebender Tiere im urbanen Raum lässt sich drei historisch gewachsenen Regimen zuordnen: Das Regime der Hygiene konstituiert die wilden Tiere der Stadt als Schädlinge, Lästlinge oder Nützlinge, das der Jagd als Nutzwild, Raubwild oder Raubzeug und das des Naturschutzes als Schutzobjekte, als heimisch oder fremd und als Leistungsträger oder Schädlinge. Dieses Regimedenken wandelt sich derzeit in der räumlichen Planungspraxis. Es wird mit ...
