Designing a model for the global energy system—GENeSYS-MOD

Löffler, Konstantin ; Hainsch, Karlo ; Burandt, Thorsten ; Oei, Pao-Yu ; Kemfert, Claudia ; Hirschhausen, Christian von (2017)

This paper develops a path for the global energy system up to 2050, presenting a new application of the open-source energy modeling system (OSeMOSYS) to the community. It allows quite disaggregate energy and emission analysis: Global Energy System Model (GENeSYS-MOD) uses a system of linear equations of the energy system to search for lowest-cost solutions for a secure energy supply, given exte...

Enhancing the understanding of urban economics by refining the spatial dimension

Kolbe, Jens (2017)

Empirical research in the field of urban economics benefits more from accurate spatial data than any other field of economics. Exploiting the spatial relationship between economic entities allows for generating comprehensive data sets which in turn allow for more comprehensive modelling and hypotheses testing. This disseration presents three essays on different aspects of urban economics which ...

Pross, Christoph (2017)

Hintergrund und Ziele: Aufgrund hoher Informationsasymmetrien zwischen Patienten und behandelnden Ärzten haben Patienten nur geringe Möglichkeiten, die Behandlung im Krankenhaus und deren Erfolgsaussichten ex ante einzuschätzen. Qualitätstransparenz kann helfen, Informationsasymmetrien zu reduzieren und Patientenmündigkeit zu stärken. Jedoch ist das Wissen über Qualitätstransparenz und deren Wi...

Chief human resources officers on top management teams: an empirical analysis of contingency, institutional, and homophily antecedents

Abt, Magdalena ; zu Knyphausen-Aufseß, Dodo (2016)

Having the director of human resources (HR) as a member of the top management team (TMT) and giving him/her the title of chief human resources officer (CHRO) indicates an important strategic and symbolic choice.

Public engagement in electricity network development: the case of the Beauly-Denny project in Scotland

Tobiasson, Wenche ; Beestermöller, Christina ; Jamas , Tooraj (2016)

Ambitious renewable energy targets and an aging infrastructure necessitate a substantial upgrading and expansion of the electricity networks around Europe and beyond. Although vital for the functioning of the economy and a green energy future, grid development projects are often met by public opposition, which increase costs and lead to lengthy planning processes. Therefore, understanding the s...

The impact of participation within formal standardization on firm performance

Wakke, Paul ; Blind, Knut ; Ramel, Florian (2016)

Several studies highlight the economic benefits of standards, while the benefit of taking part in standardization remains a rather unexplored mystery to date. In theory, standard setters not only benefit from the possibility to monitor and shape the development of standards but also access a wide range of knowledge sources in the standards committee. Therefore, we investigate how the participat...

Mansky, Thomas ; Nimptsch, Ulrike ; Cools, Andre ; Hellerhoff, Friedhelm (2017)

Die German Inpatient Quality Indicators (G-IQI) wurden für die Messung von Qualitäts- und Leistungskennzahlen mittels der sogenannten Routinedaten entwickelt (genauer gesagt für die im Rahmen der DRG-Abrechnung erfassten Daten nach § 21 KHEntgG oder § 301 SGB V). Die G-IQI Indikatoren geben übersichtlich und medizinisch sinnvoll strukturiert Auskunft über wichtige und häufige Krankheitsbilder u...

Balancing reserve provision in a decarbonized electricity sector

Lorenz, Claudio Casimir Lucas (2017)

Diese Dissertation analysiert die Chancen und Herausforderungen bei der Regelleistungsbereitstellung im dekarbonisierten Stromsektor mit Hilfe von Stromsektormodellen.

Application of Gaussian graphical models to derive dietary intake networks and association of the identified networks with risk of major chronic diseases in European Prospective Investigation into Cancer and Nutrition-Potsdam Cohort

Iqbal, Khalid (2017)

Dietary pattern analysis is a preferable approach to characterize dietary intake and understand eating behaviors. Existing data reduction methods like principal component analysis (PCA) although identify the similarity patterns of food intake in a population; it does not provide insight into how foods are consumed in relation to each other. Moreover, these methods require several subjective but...

Multi-level reinforcement in European climate and energy governance: mobilizing economic interests at the sub-national levels

Jänicke, Martin ; Quitzow, Rainer (2017)

This article explains the relatively successful performance of the European Union (EU) in climate and energy governance by two factors: (1) multi-level reinforcement and (2) the mobilization of economic interests at different levels of governance through low-carbon industrial policy. The article adds to the literature by further developing existing arguments on multi-level reinforcement in clim...

Eine institutionenökonomische Analyse der Bedarfsplanung der Stromübertragungsnetze unter Berücksichtigung der Interdependenzen zur Erzeugungsplanung

Weber, Alexander (2017)

Die vorliegende Arbeit untersucht die Frage, wie die Bedarfsplanung der Stromübertragungsnetze wirksam an öffentlichen Zielen ausgerichtet bzw. einer entsprechenden regulatorischen Kontrolle unterworfen werden kann.
