Der Beitrag behandelt die absehbaren sozialen Risiken der Digitalisierung und unterbreitet eine Reihe von Vorschlägen zur Regulierung der zukünftigen Beschäftigungsverhältnisse. Der erste Teil präsentiert auf der Basis von Projektionen einen Referenzrahmen zur Entwicklung des Arbeitsmarktes. Danach unterscheiden wir drei Gruppen von sozialen Risiken, die zeitlich gestaffelt werden: kurzfristig Einkommen, mittelfristig Weiterbildung, langfristig Alterssicherung. Im Mittelpunkt stehen die besonders betroffenen Gruppen der (Solo-)Selbstständigen und Plattformbeschäftigten.

Intelligent assistants are becoming widespread. A popular method for creating intelligent assistants is modeling the domain (and thus the assistant's capabilities) as Active Ontology. Adding new functionality requires extending the ontology or building new ones; as of today, this process is manual.We describe an automated method for creating Active Ontologies for arbitrary web forms. Our approach leverages methods from natural language processing and data mining to synthesize the ontologies. Furthermore, our tool generates the code needed to process user input.We evaluate the generated Active Ontologies in three case studies using web forms from the UIUC Web Integration Repository, namely from the domains airfare, automobile, and book search. First, we examine how much of the generation process can be automated and how well the approach identifies domain concepts and their relations. Second, we test how well the generated Active Ontologies handle end-user input to perform the desired actions. In our evaluation, Easier automatically generates 65% of the Active Ontologies' sensor nodes; the generated ontology for airfare search correctly answers 70% of the queries.

In this study we analyze the effects of energy efficiency measures on the life cycle primary energy use of a case-study (reference) 4-story wood-frame apartment building using electric resistance heating, bedrock heat pump, or cogeneration-based district heating.The reference building has an annual final heat energy demand of 110 kWh/m 2 .The energy efficiency measures analyzed are improved windows and doors, increased insulation in attic and exterior walls, installation of improved water taps, and installation of a heat recovery unit in the ventilation system.We follow the buildings' life cycles and calculate the primary energy use during the production, retrofitting, operation and end-of-life phases, and the energy reduction achieved by the measures.The results show that the measures give significantly greater life cycle primary energy savings when using resistance heating than when using district heating.However, a resistance heated building with the efficiency measures still has greater life cycle primary energy use than a district heated building without the measures.Ventilation heat recovery is the most effective measure when using resistance heating while improved windows and doors is the most effective when using district heating.This study shows the importance of considering the interactions between individual measures and the type of heat supply system when selecting energy efficiency measures.
