Toward a typology of rural Hidden Champions in times of digitalization
Rietmann, Carsten
We unravel dimensions, conditions, and outcomes of digitalization for Hidden Champions (HCs) in rural areas in Germany. As highly innovative small- and medium-sized market leaders, HCs are challenged to maintain their niche dominance but are endowed with significant resources. However, firms in rural areas face resource constraints related to digitalization and innovation. Based on qualitative interviews with 28 companies, we develop a typology of HCs with four firm types differing in their handling of digitalization: Digital HCs, HCs of Digitalization, Traditional HCs, and Digitalization-Skeptical HCs. Their digitalization-related potential and risk assessment, resource availability, strategy, and innovation types are portrayed. We provide evidence that innovative market leaders in rural areas are not necessarily also digitalization front-runners. We contribute to a deeper understanding of the nexus of digitalization, SMEs, and rural areas. Our findings have managerial and policy implications. Less innovative SME can emulate HCs’ handling of digitalization. Regional policymakers should expand firm type-specific digitalization policy formulation.

Provisioning ecosystem services play a vital role in sustaining human well-being. Agro-ecosystems contribute a significant share of these services, besides food and fodder and also fuel and fibre as well as regulating and cultural ecosystem services. Until now, the indication of provisioning ecosystem services of agro-ecosystems has been based almost only on yield numbers of agricultural products. Such an indication is problematic due to several reasons which include a disregard of the role of significant anthropogenic contributions to ecosystem service co-generation, external environmental effects and strong dependence on site conditions. We argue for an enhanced indication of provisioning ecosystem services that considers multiple aspects of their delivery. The conceptual base for such an indication has been made by prior publications which have been reviewed. Relevant points were taken up in this article and condensed into a conceptual model in order to develop a more holistic and expanded set of indictors, which was then exemplarily applied and tested in three case studies in Germany. The case studies represent different natural conditions, and the indicator set application showed that ecosystem services (ES) flow—in terms of output alone—does not characterise agro-ecosystems sufficiently. The proposed aspects of provisioning ecosystem services can give a fuller picture, for example, by input-output relationships, as it is possible by just using single indicators. Uncertainties as well as pros and cons of such an approach are elaborated. Finally, recommendations for an enhanced indication of provisioning ecosystem services in agro-ecosystems that can help to integrate agricultural principles with ideas of sustainability and site-specific land use are derived.

In order to improve the performance of well-established photocatalysts and to develop new potential photocatalyst materials, an understanding of the underlying mechanisms of photocatalytic reactions is of the utmost importance. An often neglected method for studying the mechanism is the investigation of isotope effects. Although just a few studies related to isotope effects exist, it has been shown to be a powerful tool for exploring mechanisms of photocatalytic processes. Most of the reports are focused on TiO2, which is the most studied photocatalyst, while there is a lack of data for other photocatalyst materials. This mini-review represents an overview of research utilizing isotope effects in the area of photocatalysis. The benefits and the importance of these studies will be highlighted, and the potential for these processes to be applied for the study of further photocatalytic reactions and different photocatalyst materials will be shown.
