In Germany, where 80  % of household energy goes to space heating and hot water, shifting to low-carbon solutions is crucial. Fossil-fuelled district heating networks can incorporate renewable energy via heat pumps, improving efficiency. Although heat pump design typically favours minimal temperature lifts, higher lifts can be economically viable with low electricity prices and abundant renewables. Adding thermal energy storage boosts operational flexibility. This study explores a flexible heat pump operation incorporating part load behaviour with a thermal energy storage in a German city’s district heating system to minimise costs and carbon dioxide emissions. Using a mixed-integer linear programming model, it examines the impact of temperature adjustments and storage on system efficiency. The results show that the integration of a heat pump in a district heating system reduces operating costs. Compared to a supply without a heat pump, with levelised cost of heating of 9.98 cent/kWhth and a fixed operating mode with costs between 9.96 cent/kWhth and 11.49 cent/kWhth, the flexible use results in lowest costs of 9.85 cent/kWhth, while also reducing overall CO2 emissions. Using a full factorial sensitivity analysis, the levelised cost of heating ranged between 9.15 cent/kWhth in the best case and 10.37 cent/kWhth in the worst case for the selected configuration.","lang":"eng"}],"publication":"Energy Conversion and Management","doi":"10.1016/j.enconman.2026.121714","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://www.sciencedirect.com/science/article/pii/S0196890426006837","open_access":"1"}],"article_number":"121714","intvolume":"       364","article_type":"original","date_updated":"2026-06-03T06:44:31Z","publication_status":"published","author":[{"full_name":"Rahlf, Henning Christoph","first_name":"Henning Christoph","orcid":"0009-0006-8106-2132","last_name":"Rahlf","id":"56955"},{"id":"89059","full_name":"Divkovic, Denis","last_name":"Divkovic","first_name":"Denis"},{"id":"90391","last_name":"Knorr","orcid":"0009-0005-4727-7511","first_name":"Lukas","full_name":"Knorr, Lukas"},{"first_name":"Florian","last_name":"Schlosser","full_name":"Schlosser, Florian","id":"88614"},{"id":"86954","full_name":"Meschede, Henning","last_name":"Meschede","first_name":"Henning","orcid":"0000-0002-1538-089X"}],"publication_identifier":{"issn":["0196-8904"]},"title":"Flexible operation strategies for heat pumps in district heating systems using dynamic electricity prices","year":"2026","oa":"1","project":[{"_id":"1495","name":"FlexLabQuartier"}],"citation":{"mla":"Rahlf, Henning Christoph, et al. “Flexible Operation Strategies for Heat Pumps in District Heating Systems Using Dynamic Electricity Prices.” <i>Energy Conversion and Management</i>, vol. 364, 121714, Elsevier BV, 2026, doi:<a href=\"https://doi.org/10.1016/j.enconman.2026.121714\">10.1016/j.enconman.2026.121714</a>.","bibtex":"@article{Rahlf_Divkovic_Knorr_Schlosser_Meschede_2026, title={Flexible operation strategies for heat pumps in district heating systems using dynamic electricity prices}, volume={364}, DOI={<a href=\"https://doi.org/10.1016/j.enconman.2026.121714\">10.1016/j.enconman.2026.121714</a>}, number={121714}, journal={Energy Conversion and Management}, publisher={Elsevier BV}, author={Rahlf, Henning Christoph and Divkovic, Denis and Knorr, Lukas and Schlosser, Florian and Meschede, Henning}, year={2026} }","ama":"Rahlf HC, Divkovic D, Knorr L, Schlosser F, Meschede H.

Nearly two decades ago, the service system concept was introduced as a foundational abstraction in service research, drawing on ideas from the service-dominant logic (S-D logic) of marketing. Despite its widespread adoption in service research, particularly in the IS discipline, the service system concept lacks a solid theoretical foundation. This has resulted in conceptual ambiguity and overlap with related constructs, such as service ecosystems. Moreover, it has largely remained a static analytical lens, insufficiently capturing dynamic service phenomena, including value co-creation and co-destruction, as well as the emergence of institutional arrangements. To address these limitations, we propose Luhmann’s systems theory (LST) as a robust framework for conceptualizing service systems as autopoietic (self-creating) systems, in which communication serves as the fundamental mechanism that drives value co-creation. We derive five theoretical propositions from this re-conceptualization that clarify conceptual ambiguity and allow researchers to explore dynamic service phenomena in greater depth. Given LST’s general approach, our conceptualization provides a theoretically grounded, interdisciplinary foundation for advancing service research."}],"main_file_link":[{"url":"https://link.springer.com/content/pdf/10.1007/s12525-026-00889-w.pdf","open_access":"1"}],"article_number":"37","language":[{"iso":"eng"}],"doi":"10.1007/s12525-026-00889-w","title":"Service through communication—Conceptualizing service systems with Luhmann’s systems theory","year":"2026","publication_identifier":{"issn":["1019-6781","1422-8890"]},"author":[{"full_name":"Beverungen, Daniel","first_name":"Daniel","last_name":"Beverungen"},{"last_name":"Poeppelbuss","first_name":"Jens","full_name":"Poeppelbuss, Jens"},{"last_name":"Hemmrich","first_name":"Simon","full_name":"Hemmrich, Simon"},{"last_name":"Iqbal","first_name":"Taskeen","full_name":"Iqbal, Taskeen"}],"date_updated":"2026-06-11T13:18:09Z","publication_status":"published","intvolume":"        36","article_type":"original"},{"date_updated":"2026-06-16T07:07:38Z","status":"public","title":"Effects of Vertical Price Placement on Consumer Behaviour: A VR-Based Investigation Including Eye Tracking","year":"2026","author":[{"first_name":"Hanna","last_name":"Steffens","full_name":"Steffens, Hanna"},{"full_name":"Yigitbas, Enes","orcid":"0000-0002-5967-833X","first_name":"Enes","last_name":"Yigitbas","id":"8447"},{"id":"447","full_name":"Sauer, Stefan","last_name":"Sauer","first_name":"Stefan","orcid":"0000-0003-3084-0409"}],"user_id":"8447","language":[{"iso":"eng"}],"_id":"65901","publisher":"Springer","publication":"Proceedings of the 28th International Conference on Human-Computer Interaction (HCII 2026)","citation":{"short":"H.

Especially collaborative use cases, such as remote meetings or maintenance, offer potential, but also move issues in the area of privacy and security into focus. We conducted a scoping review to gain an overview of the current situation and found a lack of clear standards, with most approaches focusing on single protection features. Using the knowledge from the scoping review, we set up and conducted expert interviews. They revealed that end-users are almost completely dependent on developers or device manufacturers regarding their options for protection. The interviews also showed that most developers put little focus on privacy and security, often due to external constraints, such as employers treating the topic as an “afterthought” and not budgeting enough time for it. The experts suggested offering better software support to developers to enable the inclusion of privacy and security with less overhead as a solution. It was also suggested that a general rise in privacy and security awareness could improve the overall situation."}],"date_created":"2026-08-10T09:39:10Z","place":"Cham","department":[{"_id":"66"},{"_id":"534"}],"type":"conference","author":[{"orcid":"0000-0001-8040-7553","last_name":"Krings","first_name":"Sarah Claudia","full_name":"Krings, Sarah Claudia","id":"64063"},{"id":"8447","full_name":"Yigitbas, Enes","last_name":"Yigitbas","first_name":"Enes","orcid":"0000-0002-5967-833X"},{"full_name":"Sauer, Stefan","last_name":"Sauer","first_name":"Stefan","orcid":"0000-0003-3084-0409","id":"447"}],"publication_identifier":{"isbn":["978-3-032-22934-2"]},"status":"public","title":"Perspectives on Privacy and Security in Collaborative AR - Insights from a Scoping Review and an Expert Interview Study","year":"2026","date_updated":"2026-08-13T09:38:27Z","publisher":"Springer Nature Switzerland","_id":"66687","language":[{"iso":"eng"}],"page":"253–276","editor":[{"first_name":"Cristiano","last_name":"Maciel","full_name":"Maciel, Cristiano"},{"full_name":"Spano, Davide Lucio","first_name":"Davide Lucio","last_name":"Spano"},{"full_name":"Ardito, Carmelo","last_name":"Ardito","first_name":"Carmelo"},{"last_name":"Freire","first_name":"André","full_name":"Freire, André"},{"full_name":"Prates, Raquel","first_name":"Raquel","last_name":"Prates"}],"user_id":"8447"},{"date_created":"2026-08-10T09:49:48Z","type":"journal_article","department":[{"_id":"66"},{"_id":"534"}],"publication":"GI - Software Engineering ","citation":{"apa":"Wüppelmann, D., &#38; Yigitbas, E.
