Rombey, Tanja ; Eckhardt, Helene ; Quentin, Wilm (2020-12-31)

Introduction: Preoperative functional capacity is an important predictor of postoperative outcomes. Prehabilitation aims to optimise patients’ functional capacity before surgery to improve postoperative outcomes.

Self-categorising and othering in migrant integration: The case of entrepreneurs in Berlin

Rashid, Lubna ; Cepeda-García, Silvia (2021-02-17)

The economic integration of migrants has become increasingly prioritised by European governments. However, Europe’s colonial past and orientalist narratives have contributed to the inevitable othering of migrants, even in the minds of those with the best of intentions. Guided by the self-categorisation theory, we postulate that those involved in supporting migrants to integrate in European soci...

Braun, Joachim ; Busse, Reinhard ; Darmon-Kern, Elisabeth ; Heine, Oliver ; Auer, Jonas ; Meyl, Tobias ; Maurer, Martin ; Hamm, Bernd ; de Bucourt, Maximilian (2020-07-01)

Background: Magnetic resonance imaging (MRI) examinations with intravenous (IV) contrast are performed worldwide in routine daily practice. In order to detect and enumerate even rare adverse events (AE) and serious adverse events (SAE), and to relate them with patients’ baseline characteristics and diagnostic effectiveness, high quantity sample size is necessary. Purpose: To assess safety, dia...

Giehl, Johannes ; Göcke, Hayri ; Grosse, Benjamin ; Kochems, Johannes ; Müller-Kirchenbauer, Joachim (2020-06-10)

The energy transformation is changing the structure of the energy sector in Europe and Germany. In this paper the current structure of the energy sector is analysed both empirically as well as theoretically. Therefore, the authors have developed the business model framework for the energy transformation (BMFE). The framework is a synthesis of classical business model designs. An exhaustive surv...

Fields of action for designing measures to avoid food losses in logistics networks

Kleineidam, Julia (2020-07-29)

The literature contains many analyses of measures against food loss. However, there exists no structured analysis of the objective of these measures. This study employs a systematic literature analysis and open expert interviews, combining the perspectives of science and practice. For each analyzed case, we identified the objectives behind the implemented measures. Using qualitative clustering,...

Do immigrant entrepreneurs have natural cognitive advantages for international entrepreneurial activity?

Middermann, Laura Helen (2020-04-01)

Are entrepreneurs with an immigration background more willing to internationalize their entrepreneurial firms compared to their nonimmigrant peers? Previous research has already emphasized that immigrant entrepreneurs possess superior human resources and social capabilities—such as international experience, networks and language skills—that help them to better identify and evaluate internationa...

Pinkow, Felix ; Iversen, Jasper (2020-11-18)

Corporations are confronted with challenges adjusting to changing technologies and markets. Seeking innovations externally through open innovation is a possible approach to go beyond the internal development of innovations. One practice of open innovation to assimilate external knowledge is corporate venture capital (CVC), meaning minority investments in entrepreneurial ventures by incumbent fi...

How Can Blockchain Technology Accelerate Energy Efficiency Interventions? A Use Case Comparison

Schletz, Marco ; Cardoso, Ana ; Prata Dias, Gabriela ; Salomo, Søren (2020-11-10)

This paper qualitatively evaluates the application of blockchain technology for three energy efficiency use cases. To achieve the Sustainable Development Agenda, energy efficiency improvements have to double by 2030. However, the adoption of energy efficiency interventions is slow due to several market barriers. Blockchain technology is a nascent technology with the potential to address these b...

How entrepreneurial orientation can leverage innovation project portfolio management

Kock, Alexander ; Gemünden, Hans Georg (2020-07-07)

Innovation project portfolio management (IPPM) is a key task in R&D management because this decision‐making process determines which R&D projects should be undertaken and how R&D resources are allocated. Previous research has developed a good understanding of the role of IPPM in R&D strategy implementation and of successful IPPM practices. But the fundamental orientations that drive the strateg...

Waitzberg, Ruth ; Davidovitch, Nadav ; Leibner, Gideon ; Penn, Nadav ; Brammli-Greenberg, Shuli (2020-05-19)

Every country has vulnerable populations that require special attention from policymakers in their response to a pandemic. This is because those populations may have specific characteristics, culture and behaviours that can accelerate the spread of the virus, and they usually have less access to healthcare, particularly in times of crisis. In order to carry out a comprehensive national interven...

The use of digitally collected patient-reported outcome measures for newly operated patients with total knee and hip replacements to improve post-treatment recovery: study protocol for a randomized controlled trial

Kuklinski, David ; Oschmann, Laura ; Pross, Christoph ; Busse, Reinhard ; Geissler, Alexander (2020-04-09)

Background The number of total knee replacements (TKRs) and total hip replacements (THRs) has been increasing noticeably in high-income countries, such as Germany. In particular, the number of revisions is expected to rise because of higher life expectancy and procedures performed on younger patients, impacting the budgets of health-care systems. Quality transparency is the basis of holistic p...

Blockchain Application for the Paris Agreement Carbon Market Mechanism—A Decision Framework and Architecture

Schletz, Marco ; Franke, Laura A. ; Salomo, Søren (2020-06-22)

This paper evaluates the suitability of blockchain technology for the Article 6.2 carbon market mechanism of the Paris Agreement. The bottom-up approach of the Paris Agreement causes challenges to the robust accounting of mitigation outcomes and information asymmetry, both of which result from a high number of heterogeneous emission accounting systems. Blockchain is an innovative technology tha...
