In today’s dynamic environments—shaped by digital transformation,\r\nevolving provider–user interactions, and shifting societal demands—these approaches face limitations in enabling continuous, context-sensitive innovation. Continuous Value Shaping emerges as a conceptual extension to service systems engineering, promoting more adaptive and co-evolutionary forms of service system development. This study examines how Continuous Value Shaping manifests through a multiple case study of three public sector projects. We identify distinct manifestations and constellations of the concept’s principles that complement classical\r\nSSE practices. As the first empirical exploration of Continuous Value Shaping, the study refines its\r\nconceptual foundation and enhances its accessibility for researchers and practitioners. We conclude with seven empirically derived propositions that inform future service systems engineering initiatives and demonstrate how Continuous Value Shaping supports the dynamic alignment of service systems with societal and systemic demands."}],"date_created":"2025-09-16T13:55:52Z","publisher":"Association for Information Systems (AIS), IEEE Computer Society Press, University of Hawaii (Manoa)","title":"From Engineering to Shaping: A Multiple Case Study on Advancing Service Systems Engineering through Continuous Value Shaping","quality_controlled":"1","year":"2026"},{"year":"2026","citation":{"chicago":"Albers, Nicola, Jochen Antel, Manuel Föcker, Lars Libuda, Judith Bühlmeier, Raphael Hirtz, Jochen Seitz, Anke Hinney, Johannes Hebebrand, and Triinu Peters. “Children and Adolescents with Psychiatric Disorders Have High Relative Leptin Levels upon Adjustment for Sex, BMI, and Pubertal Status.” <i>European Child &#38;amp; Adolescent Psychiatry</i>, 2026. <a href=\"https://doi.org/10.1007/s00787-025-02921-4\">https://doi.org/10.1007/s00787-025-02921-4</a>.","ieee":"N.

This study introduces sulfonated phenylene-bridged periodic mesoporous organosilicas (PMOs) as promising inorganic–organic hybrid PEMs, synthesized via surfactant-templating with varying alkyl chain lengths for different mesopore sizes. Post-synthetic functionalization involves nitration of phenylene moieties, reduction to amines, and ring-opening of propane or butane sultones to graft sulfonic acid groups via flexible spacers, achieving homogeneous distribution along pore walls. Post-functionalization is confirmed by powder X-ray diffraction (PXRD), revealing preserved 2D hexagonal p6mm ordering and phenylene stacking. N2 physisorption shows type IV isotherms with reduced pore volumes and pore sizes. 1H NMR is used to quantify functionalization degrees. Impedance spectroscopy on pressed pellets demonstrates proton conductivities up to 2 × 10−3 S cm−1 at 30 °C and 90% RH, depending on the functionalization degree, confirming sulfonic acid-mediated conduction."}],"language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"issn":["2079-4991"]},"citation":{"ieee":"T.

Its growing computational demands make energy efficiency a critical concern. Recent studies demonstrate FPGAs’ superior performance and energy efficiency for computing primitive ERIs, but the computation of highly contracted ERIs introduces significant algorithmic complexity and new design challenges for FPGA acceleration.In this work, we present SORCERI, the first streaming overlay acceleration for highly contracted ERI computations on FPGAs. SORCERI introduces a novel streaming Rys computing unit to calculate roots and weights of Rys polynomials on-chip, and a streaming contraction unit for the contraction of primitive ERIs. This shifts the design bottleneck from limited CPU-FPGA communication bandwidth to available FPGA computation resources. To address practical deployment challenges for a large number of quartet classes, we design three streaming overlays, together with an efficient memory transpose optimization, to cover the 21 most commonly used quartet classes in realistic atomistic simulations. To address the new computation constraints, we use flexible calculation stages with a free-running streaming architecture to achieve high DSP utilization and good timing closure.Experiments demonstrate that SORCERI achieves an average 5.96x, 1.99x, and 1.16x better performance per watt than libint on a 64-core AMD EPYC 7713 CPU, libintx on an Nvidia A40 GPU, and SERI, the prior best-performing FPGA design for primitive ERIs. Furthermore, SORCERI reaches a peak throughput of 44.11 GERIS (109 ERIs per second) that is 1.52x, 1.13x, and 1.93x greater than libint, libintx and SERI, respectively.

Using data from a real estate corporation, we simulate the effects of a wealth tax on cash flows from the rental operations. The level of detail of the data enables us to conduct analyses at the annual, regional and year of construction level. A comparison with real estate data from other sources supports external validity. The results of the simulation show that the introduction of a wealth tax can significantly reduce the cash flow from rental operations and lead to liquidity problems. On average over all observations, a wealth tax rate of 2% leads to a negative cash flow after all costs. In general, this finding implies that growth-oriented real estate is more affected by a wealth tax in terms of liquidity than rental yield-oriented real estate. Particularly in large cities with high market values but relatively low rents, the liquidity effects can be more than three times as high as in rural or industrial regions – potentially leading to a relative loss of investment attractiveness. As a wealth tax is decoupled from rental income, the tax burden is very sensitive to market developments, including the interest rate environment. As a result, investments in residential rental real estate are exposed to additional uncertainty. This additional tax uncertainty might impair the willingness to invest and should therefore be taken into account in political discussions on the reintroduction of a wealth tax.","lang":"eng"}],"status":"public","type":"working_paper","language":[{"iso":"eng"}],"_id":"63835","user_id":"96670","series_title":"TRR 266 Accounting for Transparency Working Paper Series No. 221","department":[{"_id":"187"}],"year":"2026","jel":["H22","H23","H24","R31"],"citation":{"apa":"Maiterth, R., Piper, Y., &#38; Sureth-Sloane, C.

However, apps often use third-party code, complicating accurate disclosures. This paper investigates how accurately current Android apps fulfill these requirements. In this work, we present a multi-layered definition of privacy-related data to correctly report data collection in Android apps. We further create a dataset of privacy-sensitive data classes that may be used as input by an Android app. This dataset takes into account data collected both through the user interface and system APIs. Based on this, we implement a semi-automated prototype that detects and labels privacy-related data collected by a given Android app. We manually examine the data safety sections of 70 Android apps to observe how data collection is reported, identifying instances of over- and under-reporting. We compare our prototype’s results with the data safety sections of 20 apps revealing reporting discrepancies. Using the results from two Messaging and Social Media apps (Signal and Instagram), we discuss how app developers under-report and over-report data collection, respectively, and identify inaccurately reported data categories. A broader study of 7,500 Android apps reveals that apps most frequently collect data that can\r\n                    <jats:italic>partially identify</jats:italic>\r\n                    users. Although system APIs consistently collect large amounts of privacy-related data, user interfaces exhibit some more diverse data collection patterns.

This enhances dimensional accuracy in sparse-view computed tomography (CT). However, existing approaches offer no direct means to exploit this criterion for automatic scan-angle optimization. We propose a method that uses a virtual representation of the CT setup, including an STL surface model of the inspected part, to automatically identify taskspecific scan angles. Using elementary vector calculus, the algorithm determines projection directions that generate tangential X-rays for targeted surface segments. To support different levels of geometric complexity, we introduce two variants of the angle-selection procedure. The methods were experimentally validated on two objects with distinct absorption and geometric characteristics. For a steel gauge block, employing the minimum number of task-specific projections required for surface-data completeness substantially outperformed a conventional high-projection scan. For a geometrically more complex test object, surface-related errors were still reduced within the region of interest. The proposed approach – particularly suited for flat surface structures and not accounting for image-degrading factors other than cone-beam artifacts – shows promise for high-throughput dimensional metrology of mono-material parts.</jats:p>","lang":"eng"}],"publication":"e-Journal of Nondestructive Testing","main_file_link":[{"open_access":"1","url":"https://www.ndt.net/article/ctc2026/papers/ict26_Contribution_184.pdf"}],"conference":{"location":"Linz","name":"15th Conference on Industrial Computed Tomography (iCT)"},"doi":"10.58286/32560","date_updated":"2026-02-12T10:41:45Z","oa":"1","author":[{"last_name":"Butzhammer","full_name":"Butzhammer, Lorenz","first_name":"Lorenz"},{"first_name":"Matthias Robert Oskar","last_name":"Braun","full_name":"Braun, Matthias Robert Oskar"},{"full_name":"Herath, Colin","last_name":"Herath","first_name":"Colin"},{"first_name":"Tino","full_name":"Hausotte, Tino","last_name":"Hausotte"}],"volume":31,"citation":{"ama":"Butzhammer L, Braun MRO, Herath C, Hausotte T.
