German public utilities

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

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...

Background: The aim of this study was to assess the quality of reporting sample size calculation and underlying design assumptions in pivotal trials of high-risk medical devices (MDs) for neurological conditions. Methods: Systematic review of research protocols for publicly registered randomized controlled trials (RCTs). In the absence of a published protocol, principal investigators were cont...

Social innovation & social entrepreneurship

Mostovova, Elena (2019)

The main purpose of this doctoral thesis is to improve our understanding of social innovation and social entrepreneurship phenomena and the process of social value creation. The four articles add to conceptualization efforts and make empirical contributions on the types of social ventures as well as operationalization and measurement of social value generation. Methods used combine structural l...

Overcoming Barriers to Successfully Commercializing Carbon Dioxide Utilization

Kant, Marvin (2017)

The successful transition to a low-carbon economy hinges on innovative solutions and collaborative action on a global scale. Sustainable entrepreneurship is thereby recognized as a key driver in the creation and transformation of ecologically and socially sustainable economic systems. The purpose of this article is to contribute to this topic by understanding commercialization barriers for stro...

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. In the simulation ZUG UM ZUG 2015, participants form union and management negotiation teams to negotiate with each other (first level) and with a management or union “tariff commission,” which has to approve proposed contracts (second ...

Statistical Matching of Administrative and Survey Data

Rasner, Anika ; Frick, Joachim R. ; Grabka, Markus Michael (2013)

Using population representative survey data from the German Socio-Economic Panel (SOEP) and administrative pension records from the Statutory Pension Insurance, the authors compare four statistical matching techniques to complement survey information on net worth with social security wealth (SSW) information from the administrative records. The unique properties of the linked data allow for a s...

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...

The Open and the Closed Corporation as Conflicting forms of Organization

Gebert, Diether ; Boerner, Sabine (1999)

Organizational change is discussed in the context of a conceptual model resting on philosophical, sociological, and anthropological foundations. Distinguishing between an open and a closed form of organization, the authors focus on two theses. The first is that organizations as societal systems are marked by the simultaneous existence of two forms of organization that are mutually exclusive in ...

[Book Review:] Marc J. Schabracq, Jacques A. M. Winnubst and Cary L. Cooper (eds.): Handbook of Work and Health Psychology. 1996, New York: Wiley.

Gebert, Diether (1998)

This handbook represents an attempt to inform the reader about key aspects of two hitherto separately treated fields - work and health psychology and to interrelate them more closely.

Dealing With Incomplete Household Panel Data in Inequality Research

Frick, Joachim R. ; Grabka, Markus Michael ; Groh-Samberg, Olaf (2012)

In trying to capture complete within-household heterogeneity, household panel surveys typically try to interview all adult household members. Following from this, such surveys tend to suffer from partial unit nonresponse (PUNR), that is, the nonresponse of at least one member of an otherwise participating household, most likely yielding an underestimation of aggregate household income. Using da...

Uncharted Territories of Organizational Research: The Case of Karl Popper's Open Society and its Enemies

Armbrüster, Thomas ; Gebert, Diether (2002)

This paper argues that Karl Popper's notions in his work 'The Open Society and Its Enemies' offer an approach to under-explored issues in organizational research, independent of Popper's epistemology. Popper's thoughts on the philosophy of science have largely been rejected in organization studies, and his socio-philosophical notions have hardly been considered. Yet they provide a frame of refe...

The Paradox of Revenge in Conflicts

Amegashie, J. Atsu ; Runkel, Marco (2012)

The authors consider a two-period game of conflict between two factions, which have a desire for revenge. It is shown that, in contrast to conventional wisdom, the desire for revenge need not lead to escalation of the conflict. The subgame-perfect equilibrium is characterized by two effects: a value of revenge effect (i.e., the benefit of exacting revenge) and a self-deterrence effect (i.e., th...

Sustainable entrepreneurship for commercialising radical clean technologies

Kant, Marvin (2018)

The purpose of this research is to increase our understanding of how sustainable entrepreneurship (SE) can enable the commercialisation of radical clean technologies (cleantech). The aim is to realise more sustainability-oriented innovation (SOI) in order to move towards an economy with closed carbon loops and an efficient (re-)use of resources. Previous research focussed on drivers, barriers,...

Cloud- und Open Source-basierte Integrationsplattformen

Theilig, Max-Marcel ; Pröhl, Thorsten ; Felfeli, Jonas ; Holz, Julia (2018)

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...

A systematic review of randomized controlled trials of mHealth interventions against non-communicable diseases in developing countries

Stephani, Victor ; Opoku, Daniel ; Quentin, Wilm (2016-07-15)

Background The reasons of deaths in developing countries are shifting from communicable diseases towards non-communicable diseases (NCDs). At the same time the number of health care interventions using mobile phones (mHealth interventions) is growing rapidly. We review studies assessing the health-related impacts of mHealth on NCDs in low- and middle-income countries (LAMICs). Methods A syst...
