Business model innovation in strategic alliances: a multi‐layer perspective
(2020-04-17)
Business model innovation (BMI) has recently become a topic of interest for research as well as corporate practice. However, we lack specific insights into actors, drivers, and different forms of BMI as the concept is by now mainly addressed in a very general way. In this paper, we analyze how BMI takes place in strategic alliances with the focus of enhancing the recent knowledge about BMI by developing a concept that links firm‐level BMI with alliance‐driven innovation of business models. Against the background of ...

Bewegte Lebenswelten – Einblicke in Raum- und Bewegungserleben in Ganztagsschulen aus Sicht von Kindern
(2020-11-17)
Vor dem Hintergrund des flächendeckenden Ausbaus ganztägiger Bildungsangebote als einem der größten bildungspolitischen Reformprojekte in Deutschland und des Diskurses zur Institutionalisierung von Kindheit bestand das Ziel der diesem Beitrag zugrundeliegenden Studie darin, mit einem partizipativ ausgerichteten Mixed-Methods-Design die Perspektive der Kinder auf Ganztagsschule als ihren Lebensort zu beleuchten. Mit einer aneignungstheoretischen Perspektive auf das Erleben von Raum und Bewegung in vorwiegend informellen ...

Agil, hierarchiefrei und selbstorganisiert im New Work oder überwältigt von Systemstrukturen und unterdrückten gruppendynamischen Prozessen im New Office
(2020-11-03)
Dieser Beitrag in der Zeitschrift Gruppe. Interaktion. Organisation. (GIO) stellt eine explorative qualitative Studie zum Erleben von Sinn und Bindung durch Mitarbeitende in agilen New Work Umwelten vor, indem sie Wirkungen von Selbstorganisation, flachen Hierarchien, und elaborierten agilen Systemarchitekturen im Gegenlicht von persönlichen Beziehungen, gruppendynamischen Prozessen und Aspekten des psychologischen Empowerments betrachtet.
Globalisierung, Digitalisierung und demographischer Wandel lassen Wettbewerb ...

Engineering Challenges Ahead for Robot Teamwork in Dynamic Environments
(2020-02-18)
The increasing number of robots around us creates a demand for connecting these robots in order to achieve goal-driven teamwork in heterogeneous multi-robot systems. In this paper, we focus on robot teamwork specifically in dynamic environments. While the conceptual modeling of multi-agent teamwork was studied extensively during the last two decades and commercial multi-agent applications were built based on the theoretical foundations, the steadily increasing use of autonomous robots in many application domains gave ...

Sozialpolitik als Problemarbeit an Menschen und an Institutionen
(2020-10-28)
In der Soziologie sozialer Probleme ist Sozialpolitik seit jeher ein wichtiger Aspekt, wird aber nur selten explizit in den Mittelpunkt gestellt. Der Beitrag verdeutlicht die Relevanz von Sozialpolitik sowie ihrer organisationalen und professionellen Bezugspunkte (Wohlfahrtspflege, soziale Dienstleistungsberufe) im Kontext der Soziologie sozialer Probleme und nimmt eine Einordnung im Rahmen unterschiedlicher institutioneller Logiken vor. Mit Blick auf das Wechselspiel von Definitions- und Bearbeitungsprozessen ‚von ...

Additive surface texturing of cutting tools using pulsed laser implantation with hard ceramic particles
(2020-09-15)
In recent years surface texturing of the cutting tools has proved to improve tribological characteristics at tool/chip and tool/workpiece interface and help to reduce cutting and feed forces as well as tool wear. Most, if not all, of the studies have focused on subtractively made textures whereby the material is removed from the surface. This study investigates the performance of additively made surface structures whereby hard ceramic particles are dispersed in the form of dome shaped textures on the surface of the ...

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 ...

Comment on ‘Kidron, G. J. (2018). Biocrust research: A critical view on eight common hydrological‐related paradigms and dubious theses. Ecohydrology, e2061’
(2020-06-24)
Kidron (2018) uses a straw man argument in an attempt to debunk eight putative hydrological‐related paradigms he believes to be “common among hydrologists, ecologists, or microbiologists that investigate biocrusts.” These paradigms relate to the roles of physical crusts and vascular plants in biocrust development, the major drivers (climate, porosity, hydrophobicity, and exopolysaccharides) of hydrology (infiltration and runoff), and the effect of mosses on hydrology and therefore vascular plants. We see two major ...

Biomass Performance and Competition Effects in an Established Temperate Agroforestry System of Willow and Grassland—Results of the 2nd Rotation
(2020-11-19)
Agroforestry systems (AFSs) are promoted as environmentally friendly and climate-change-resilient cultivation systems with the potential of increasing ecosystem services. Especially under temperate climatic conditions, the implementation in agricultural practice is low so far, inter alia due to the lack of knowledge regarding longer-term effects of such systems. This study investigated biomass yields and crop development during the second rotation of an alley cropping system with willows (clone “Tordis” ((Salix ...
