Effective and needed, but not used: Why do mobile phone-based health interventions in Africa not move beyond the project status?

Stephani, Victor (2019)

Reviews have shown that mobile phone-based health interventions (mHealth interventions) are capable of improving health outcomes of patients in Africa, particularly for patients with chronic diseases such as non-communicable diseases (NCDs). But currently, most mHealth interventions are stopped after the pilot and the funding of the donors has ceased. The aim is to identify the reasons for the ...

Lessons Learned from Establishing the Energy-Informatics Business Model: Case of a German Energy Company

Grosse, Matti ; Send, Hendrik ; Schildhauer, Thomas (2019-02-07)

Energy and utilities companies find themselves in a paradoxical situation in which their traditional business models are losing profitability, and they must advocate energy efficiency and climate-protection goals, and thus encourage their customers to save energy. As a result, they must partially cannibalize their business models and experiment with new models and techniques. Energy Informatics...

Physician decision making on new technologies and the role of coverage with evidence development

Felgner, Susanne ; Ex, Patricia ; Henschke, Cornelia (2018)

OBJECTIVES: To foster value-based pricing and coverage with evidence development in Germany, certain new diagnostic and treatment methods have been subject to a benefit assessment since 2016 to determine their reimbursement. Although this is a paradigm shift, the German approach is limited to some few specific technologies for which reimbursement is requested. As physicians encounter this regul...

Institutional entrepreneurs: decision-making, networking and collective leadership

Cabero Tapia, Shirley Patricia (2019)

Institutions, as mechanisms of social order, evolve over long periods of time. In turn, institutional entrepreneurship recognizes the possibility that individuals can alter the evolution of institutions by creating and transforming them. However, little is know about the management of institutional change projects, especially when institutional entrepreneurs have low resources and their project...

How User-Innovators Pave the Way for a Sustainable Energy Future: A Study among German Energy Enthusiasts

Grosse, Matti (2018)

The existence of user-innovators in the household sector is undeniable. Prior research provided evidence on the vast scope of product developments by household sector users and documented a large set of individual user-innovator characteristics to explain their behavior. What has largely been neglected as a potential source of user innovation activities are product- and technology-specific fact...

Triggers of Collaborative Innovation in Online User Communities

Grosse, Matti ; Pohlisch, Jakob ; Korbel, Jakob J. (2018)

This study contributes to the understanding of collaborative innovation in online user communities. Aside from providing evidence for the existence of these communities, prior research focused on users’ motivations, backgrounds, and roles at the micro level but largely neglected to examine the effects of individual user activities on joint activities at the community level. By applying a netnog...

Collective bargaining as a two-level game: Direct learner-expert interactions

Schilling, Martin S. ; Mulford, Matthew A. ; Geiger, Ingmar R. (2006)

In this article, the authors introduce a new feature to model the collective bargaining process: a two-level game setting with direct learner-expert interaction.

Die Digitalisierung des deutschen Mittelstands schreitet kontinuierlich voran, wenngleich bei noch vielen Unternehmen grundlegende Komponenten einer Digitalinfrastruktur fehlen oder nicht im vollen, gewünschten Umfang vorhanden sind: Wie eine eigene Website, CRM- oder ERP-Systeme. Im Zuge des Fortschritts sind in den Unternehmen in den letzten Jahren mehr und mehr unterschiedliche IT Systeme en...

The Best, the Worst, and the Hardest to Find: How People, Mobiles, and Social Media Connect Migrants In(to) Europe

Borkert, Maren ; Fisher, Karen E. ; Yafi, Eiad (2018)

For displaced people, migrating into Europe has highly complex information needs about the journey and destination. Each new need presents problems of where to seek information, how to trust or distrust information, and financial and other costs. The outcomes of receiving poor or false information can cause bodily harm or death, loss of family, or financial ruin. We aim to make two major contri...
