Temporal Aggregation of Time Series to Identify Typical Hourly Electricity System States: A Systematic Assessment of Relevant Cluster Algorithms

Comprehensive numerical models are pivotal to analyze the decarbonization of electricity systems. However, increasing system complexity and limited computational resources impose restrictions to model-based analyses. One way to reduce computational burden is to use a minimum, yet representative, set of system states for model simulation. These states characterize fluctuating renewable generation and ...

Model-Related Outcome Differences in Power System Models with Sector Coupling: Quantification and Drivers

This paper presents the results of a multi-model comparison to determine outcome deviations resulting from differences in power system models. We apply eight temporally and spatially resolved models to 16 stylized test cases. These test cases differ in their renewable energy supply share, technology scope, and optimization scope. We focus on technologies for balancing the variability of power generation, ...

From German Internet Panel to Mannheim Corona Study: Adaptable Probability‐Based Online Panel Infrastructures during the Pandemic

The outbreak of COVID‐19 has sparked a sudden demand for fast, frequent and accurate data on the societal impact of the pandemic. This demand has highlighted a divide in survey data collection: Most probability‐based social surveys, which can deliver the necessary data quality to allow valid inference to the general population, are slow, infrequent and ill‐equipped to survey people during a lockdown. ...

'Climate Neutral' is a Lie — Abandon It as a Goal: Correspondence

Social Status Concerns and the Political Economy of Publicly Provided Private Goods

We analyse the political economy of the public provision of private goods when individuals care about their social status. Status concerns motivate richer individuals to vote for the public provision of goods they themselves buy in markets: a higher provision level attracts more individuals to the public sector, enhancing the social exclusivity of market purchases. Majority voting may lead to a public ...

Lights along the Frontier: Convergence of Economic Activity in the Proximity of the Polish-German Border, 1992–2012

This paper studies regional economic development on the municipality-level in Poland and Germany along the Oder–Neisse border. We use high-quality satellite night-time light intensity data as an innovative and comparable measure to proxy for overall economic activity on both sides of the border consistently over a long period of time (1992–2012). We use descriptive heat maps as well as regression analysis ...

Strengthening Gender Justice in a Just Transition: A Research Agenda Based on a Systematic Map of Gender in Coal Transitions

For climate change mitigation, a rapid phase-out of fossil fuels such as coal is necessary. This has far-reaching gender-specific consequences. This paper presents a systematic map of the literature that examines the impact of historical coal phase-out processes on women and their role in these processes. The search process consisted of screening over 3100 abstracts and reading 247 full-text studies. ...

Gender Score Development in the Berlin Aging Study II: A Retrospective Approach

In addition to biological sex, gender, defined as the sociocultural dimension of being a woman or a man, plays acentral role in health. However, there are so far few approaches to quantify gender in a retrospective manner inexisting study datasets. We therefore aimed to develop a methodology that can be retrospectively applied to assessgender in existing cohorts. We used baseline data from the Berlin ...

Waiting for Kin: A Longitudinal Study of Family Reunification and Refugee Mental Health in Germany

Involuntarily or planned – many refugees flee their home country alone, leave behind spouses and children but also siblings, parents and other family members they otherwise care for. Reunification in hosting communities is difficult, as governments limit institutional family reunifications and the individual journey of kin is dangerous and often illegal. Having family abroad is mentally distressing ...

Bekanntheit und Nutzung von digitalen Gesundheitsangeboten in Deutschland: eine bevölkerungsrepräsentative Querschnittsuntersuchung

Ziel der Studie Angesichts aktueller gesundheitspolitischer Bestrebungen zur eHealth-Implementierung stellt sich die Frage, welche Bevölkerungsgruppen Online-Gesundheitsangebote in Anspruch nehmen, um diese gezielter auf Nutzerbedürfnisse abstimmen zu können. Die Studie untersucht, ob Unterschiede in der Nutzung von Gesundheitsinformationen und psychologischer Online-Beratung auf Basis soziodemografischer ...
