Active learning (AL) addresses this challenge by strategically selecting representative and informative data points to reduce labeling efforts. This paper focuses on an AL scenario in which only a very limited number of labels can be acquired. We propose an algorithm operating in two phases: (1) an exploration phase that prioritizes representative and diverse data points using density-driven criteria, and (2) an exploitation phase that combines predictive uncertainty with density weighting to select informative samples from densely populated regions. This enhances both representativeness and informativeness. Our results demonstrate significant improvements in model quality compared to other algorithms typically employed for this scenario, across various scenarios involving imbalanced data in classification tasks and skewness in regression tasks. Through this work, we aim to provide a new algorithm for this scenario and investigate general principles for AL. While most AL studies focus on either classification or regression, our work applies the algorithms to both. Therefore, we can analyze the differences between classification and regression problems and their effects on AL strategies. Furthermore, we explore different categories of AL criteria and their effectiveness in the low-budget regime. These results also provide insight into the cold-start problem, which involves selecting an initial labeled set and is faced by many model-based AL methods.}, author = {Jaster, Bjarne and Tharwat, Alaa and Sheikh, Eiram Mahera and Kohlhase, Martin and Schenck, Wolfram}, booktitle = {Machine Learning and Principles and Practice of Knowledge Discovery in Databases.

Health literacy is essential for treatment success. To improve knowledge about the biopsychosocial factors influencing FAP and support its management, we developed an educational multimedia website (https://meine-bauchstelle.com). Methods: In a multicenter randomised controlled trial (RCT), patients with FAP (N = 166, age 5–17 years, M = 10.8, SD = 3.31; 53.6% female) and their parents were randomly assigned to an intervention group (IG: access to the website before the first measurement) or a control group (CG: no access to the website during data collection). The primary outcome was health literacy (knowledge and health behaviour) and secondary outcomes were abdominal pain symptoms and the physician-patient/parent interactions. Group differences were analysed using t-tests and multilevel models. Results: Patients in the IG who visited the website demonstrated significantly higher initial knowledge scores compared to the CG. Moreover, they reported significantly less pain-related disability across three assessments over 3 months. Parents who visited the website rated the physician-parent interaction significantly more positively than those in the CG. Conclusions: The educational website efficiently increased patient knowledge about FAP and improved certain pain-related behaviours. It serves as an effective tool in conveying information about FAP in clinical practice. Future applications could extend to preventive measures in schools and other settings. Significance Statement: The educational website about functional abdominal pain is effective in transferring knowledge, reducing pain-related disability, and improving physician-parent interactions. It can support physicians in day-to-day clinical practice by referring patients to the website for further information and might be extended as a preventive measure in schools.}, author = {Neß, Verena and Humberg, Clarissa and Rau, Lisa‐Marie and Eidt, Leandra and Berger, Thomas and Claßen, Martin and Syring, Nils Christian and Berrang, Jens and Vietor, Christine and Buderus, Stephan and Hirschfeld, Gerrit and Becker‐Emden, Christina and Wager, Julia}, issn = {1532-2149}, journal = {European Journal of Pain}, number = {3}, publisher = {Wiley}, title = {{A Randomised Controlled Trial Testing the Efficacy of an Educational Website About Functional Abdominal Pain for Children and Adolescents}}, doi = {10.1002/ejp.70249}, volume = {30}, year = {2026}, } @article{6938, abstract = { Background - Cognitive behavioral therapy (CBT) is one of the most widely established treatments for mental disorders in children and adolescents and is empirically supported across a wide range of disorders, including evidence from routine care. However, evidence on long-term maintenance of effects in routine outpatient care is still limited, particularly across diagnostic groups. This study examines the long-term, cross-diagnostic effectiveness of CBT in children and adolescents treated under routine outpatient care conditions.
Methods - Analyses are based on pre-existing routine outcome monitoring data from 1225 patients (mean age = 14.00 years, SD = 3.24) receiving CBT, collected between 2017 and 2025. Symptoms were assessed using the parent- and patient-reported Strengths and Difficulties Questionnaire (SDQ) at pre-treatment, post-treatment and at 6-, 12- and 24-month follow-ups. Additional self-rated treatment-success ratings were collected at follow-up (covering expectations fulfilled, perceived helpfulness, problem recurrence and perceived change). Effectiveness was described using group means as well as clinical significance. Pre- to post- and pre- to follow-up changes were analysed using paired Wilcoxon signed-rank tests. Associations between follow-up SDQ scores and self-rated treatment success were examined using partial Spearman correlations controlling for baseline SDQ.
Results - Across both parent- and patient-reported SDQ assessments, total difficulties and problem subscales showed significant improvements from pre- to post-treatment and from pre-treatment to all follow-up time points. Effect sizes were consistently moderate-to-large ( r_rb = 0.59–0.77), with sustained effects up to 24 months. Higher follow-up SDQ difficulties were associated with lower self-rated treatment success across multiple follow-up ratings, with strongest associations observed for problem recurrence and change compared to before treatment. Sensitivity analyses restricted to participants in the clinical range at baseline (SDQ ≥ 17) yielded consistent results.
Conclusions - Routine outpatient CBT for children and adolescents was associated with meaningful symptom improvements that persisted up to two years after treatment. Clinically significant change analyses indicated that while many patients showed reliable improvement, a substantial proportion remained classified as unchanged according to conservative criteria. Subjective follow-up ratings were consistent with standardized symptom outcomes, supporting the perceived durability of treatment success under routine care conditions in a diagnostically heterogeneous sample. }, author = {Hüwelmeier, Matthis Michael and Staniczek, Lena and Schneider, Silvia and Zhang, Xiao Chi and Wannemüller, André and Hirschfeld, Gerrit and Krause, Karen and Friedrich, Sören and von Brachel, Ruth}, issn = {2050-7283}, journal = {BMC Psychology}, number = {1}, publisher = {Springer Science and Business Media LLC}, title = {{Long-term effectiveness of cognitive behavioral therapy (CBT) for children and adolescents in routine care}}, doi = {10.1186/s40359-026-04667-3}, volume = {14}, year = {2026}, } @article{6928, author = {Korte, Philipp}, issn = {1758-9568}, journal = {Strategy & Leadership}, pages = {1--32}, publisher = {emerald insight}, title = {{Leading across time zones: a strategic framework for leading virtual teams in global organizations}}, doi = {10.1108/SL-10-2025-0354}, year = {2026}, } @article{6924, author = {Berger, Ursula and Biehler, Rolf and Binder, Karin and Elmer, Christina and Ertz, Florian and Hotz, Thomas and Huber, Sarah and Ickstadt, Katja and Kauermann, Göran and Küchenhoff, Helmut and Lübke, Karsten and Münnich, Ralf and Schüller, Katharina and Skill, Thomas and Weihs, Claus and Weinert, Henrike and Weisser, Christoph}, issn = {1863-8163}, journal = {AStA Wirtschafts- und Sozialstatistisches Archiv}, publisher = {Springer}, title = {{Daten, Künstliche Intelligenz und Evidenz - neue Anforderungen an die Statistikausbildung an Hochschulen: Diskussion und Erwiderung}}, doi = {10.1007/s11943-026-00372-0}, year = {2026}, } @inbook{6926, abstract = {Inklusion ist ein umfassendes Menschenrecht und zentraler Bezugspunkt für Selbstvertreter:innen und soziale Bewegungen.
