Effective monitoring provides the relevant information on time. This can be achieved with exhaustive monitoring causing a high overhead consumption of economical and ecological resources. In contrast, our generic adaptive monitoring approach supports effectiveness with increased efficiency. Also, it adapts to changes regarding the information demand and the monitored system without additional configuration and software implementation effort. The approach observes the executions of runtime model queries and processes change events to determine the currently required monitoring configuration. In this paper we explicate different possibilities to use the approach and evaluate their characteristics regarding the phenomenon detection time and the monitoring effort. Our approach allows balancing between those two characteristics. This makes it an interesting option for the monitoring function of self-adaptive systems because for them usually very short-lived phenomena are not relevant.}, language = {en} } @misc{BrandGiese2019, author = {Brand, Thomas and Giese, Holger Burkhard}, title = {Towards Generic Adaptive Monitoring}, series = {2018 IEEE 12th International Conference on Self-Adaptive and Self-Organizing Systems (SASO)}, journal = {2018 IEEE 12th International Conference on Self-Adaptive and Self-Organizing Systems (SASO)}, publisher = {IEEE}, address = {New York}, isbn = {978-1-5386-5172-8}, issn = {1949-3673}, doi = {10.1109/SASO.2018.00027}, pages = {156 -- 161}, year = {2019}, abstract = {Monitoring is a key prerequisite for self-adaptive software and many other forms of operating software. Monitoring relevant lower level phenomena like the occurrences of exceptions and diagnosis data requires to carefully examine which detailed information is really necessary and feasible to monitor. Adaptive monitoring permits observing a greater variety of details with less overhead, if most of the time the MAPE-K loop can operate using only a small subset of all those details. However, engineering such an adaptive monitoring is a major engineering effort on its own that further complicates the development of self-adaptive software. The proposed approach overcomes the outlined problems by providing generic adaptive monitoring via runtime models. It reduces the effort to introduce and apply adaptive monitoring by avoiding additional development effort for controlling the monitoring adaptation. Although the generic approach is independent from the monitoring purpose, it still allows for substantial savings regarding the monitoring resource consumption as demonstrated by an example.}, language = {en} } @article{HuberRiglingBebietal.2013, author = {Huber, Robert and Rigling, Andreas and Bebi, Peter and Brand, Fridolin Simon and Briner, Simon and Buttler, Alexandre and Elkin, Che and Gillet, Francois and Gret-Regamey, Adrienne and Hirschi, Christian and Lischke, Heike and Scholz, Roland Werner and Seidl, Roman and Spiegelberger, Thomas and Walz, Ariane and Zimmermann, Willi and Bugmann, Harald}, title = {Sustainable land use in Mountain Regions under global change synthesis across scales and disciplines}, series = {Ecology and society : a journal of integrative science for resilience and sustainability}, volume = {18}, journal = {Ecology and society : a journal of integrative science for resilience and sustainability}, number = {3}, publisher = {Resilience Alliance}, address = {Wolfville}, issn = {1708-3087}, doi = {10.5751/ES-05499-180336}, pages = {20}, year = {2013}, abstract = {Mountain regions provide essential ecosystem goods and services (EGS) for both mountain dwellers and people living outside these areas. Global change endangers the capacity of mountain ecosystems to provide key services. The Mountland project focused on three case study regions in the Swiss Alps and aimed to propose land-use practices and alternative policy solutions to ensure the provision of key EGS under climate and land-use changes. We summarized and synthesized the results of the project and provide insights into the ecological, socioeconomic, and political processes relevant for analyzing global change impacts on a European mountain region. In Mountland, an integrative approach was applied, combining methods from economics and the political and natural sciences to analyze ecosystem functioning from a holistic human-environment system perspective. In general, surveys, experiments, and model results revealed that climate and socioeconomic changes are likely to increase the vulnerability of the EGS analyzed. We regard the following key characteristics of coupled human-environment systems as central to our case study areas in mountain regions: thresholds, heterogeneity, trade-offs, and feedback. Our results suggest that the institutional framework should be strengthened in a way that better addresses these characteristics, allowing for (1) more integrative approaches, (2) a more network-oriented management and steering of political processes that integrate local stakeholders, and (3) enhanced capacity building to decrease the identified vulnerability as central elements in the policy process. Further, to maintain and support the future provision of EGS in mountain regions, policy making should also focus on project-oriented, cross-sectoral policies and spatial planning as a coordination instrument for land use in general.}, language = {en} } @article{HeinzHeidenreichWenholdetal.2011, author = {Heinz, Kathrin and Heidenreich, Thomas and Wenhold, Franziska and Brand, Ralf}, title = {Mindfulness and acceptance basic principles and perspectives of a new approach in sport psychology training}, series = {Zeitschrift f{\"u}r Sportpsychologie}, volume = {18}, journal = {Zeitschrift f{\"u}r Sportpsychologie}, number = {4}, publisher = {Hogrefe}, address = {G{\"o}ttingen}, issn = {1612-5010}, doi = {10.1026/1612-5010/a000056}, pages = {145 -- 154}, year = {2011}, abstract = {Mindfulness and acceptance describe the skills necessary to experience emotions and thoughts (e.g., performance-interfering cognitions) consciously and without judging them.
