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...

Dabei bestehen einige Einschränkungen und offene Punkte in der Regelung, die es zu diskutieren gilt. Ziel ...

German public utilities: organisation and productivity

Stiel, Caroline (2018)

Since 1998, public firms have had to adapt to a market environment that is very different from the post-war era in Europe. The liberalisation of services of general economic interest across Europe led to competition between public and private providers, while new technologies require infrastructure investment and innovative solutions. In addition, urbanisation and population ageing pose new cha...

Institutional entrepreneurs: decision-making, networking and collective leadership

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)

Implementing Process Innovations

Krause, Diana E. ; Gebert, Diether ; Kearney, Eric (2007)

Previous research leaves open which facets of leadership foster the implementation of process innovations. In this study, the authors analyze the effects of delegative-participative and consultative-advisory leadership, respectively, on the implementation success of process innovations. They argue that each of these leadership behaviors entails specific advantages and risks and that therefore t...

Empowerment in the Context of Transformational Change: A Study of Acquisitions and Privatizations in Eastern Europe

Gebert, Diether ; Piske, Reiner ; Baga, Tünde ; Lanwehr, Ralf ; Kearney, Eric (2006)

This paper examines conditions under which empowerment (decision autonomy, dialogic leadership) is connected with positive and negative effects, respectively, in regard to managing transformational change in Eastern Europe. Acquisitions by foreign investors in Poland and Russia (N = 45 companies) and privatizations through employee buy-out in Romania (N = 5 companies) are contrasted in this stu...
