Soforthilfe bei Schulstress : digitales Feedbacksystem für Jugendliche
Get PDFBackground and objective: School-related stress is a significant health burden for adolescents. Digital wearables offer new opportunities to monitor physiological stress responses in real time and to support self-regulation through tailored feedback. The aim of this exploratory study was to investigate adolescents’ acceptance, experiences, and attitudes toward wearable stress sensors in the school context, and to identify indications of their potential benefits.
Methods: Data collection took place in May 2025 in two ninth-grade classes (N = 22). A mixed-methods design included:
1. Physiological stress monitoring with EDA sensors (Movisens GmbH) during several lessons, capturing electrodermal activity as indicators of stress responses,
2. Questionnaire surveys via Unipark (after individual lessons and at the end of the school day),
3. Semi-structured interviews with 18 adolescents exploring subjective perceptions, daily experiences, and attitudes toward the technology.
Quantitative data were analyzed with SPSS and qualitative data with MAXQDA (inductive thematic analysis). The physiological stress data are still being analyzed; first results focus on subjective perceptions.
Results: Most students perceived the sensor as unobtrusive. About 70% reported that it did not interfere with lessons, while 80% noticed peers wearing the device without feeling disturbed. The “double-tap” function to mark subjective stress was widely used and perceived as a reflective tool. Interviews indicated an overall positive attitude, highlighting curiosity, useful self-observation, and openness to personalized feedback (e.g., breathing exercises or haptic vibration when stress was elevated). Criticism focused mainly on size, weight, and visibility of the device, as well as the adhesive electrodes. Data privacy emerged as a key concern; however, most participants accepted teacher access if intended for support rather than evaluation.
Discussion and conclusion: Findings suggest that wearable stress sensors are generally well accepted in schools, provided that design and functionality are youth-friendly and data privacy is transparently addressed. Personalized feedback appears desirable and potentially effective in promoting self-regulation. The added value of such technologies lies in combining real-time monitoring with low-threshold interventions. Further analysis of physiological data will provide additional insights into the interaction between objective and subjective stress measures

Assessing airport surface traffic performance from open sources of aviation data
Get PDFThis study investigates the potential of crowdsourced open aviation data, specifically ADS-B trajectories and Open-StreetMap infrastructure models, to analyse airport surface operations. Surface position messages in ADS-B often suffer from challenges related to Global Navigation Satellite System localization accuracy and Mode S receiver data reception, such as multipath interference. Similarly, the crowdsourced efforts to enrich OpenStreetMap’s infrastructure data are primarily focused on general mapping purposes rather than detailed operational analysis. In this paper, we review the existing literature on airport surface performance assessment and develop a methodology to adapt these techniques for open ADS-B data. Our approach focuses on filtering trajectory data to map positional information, where available, into a timed sequence of taxiway segments. These sequences are used to calculate key performance indicators from the literature, such as saturation rates, taxi-out time distributions as a function of departing aircraft queue sizes, and flow-density relationships (fundamental diagrams). We apply this methodology to a data set of selected days in 2024 at Zurich International Airport

sozipedia: Intervention, die : ein auditives Nachwort zur Kolumne über Fachbegriffe auf Abwegen
No full textWenn er den Begriff «Intervention» hört, gehen bei Menno Labruyère gleich die Alarmglocken an. Denn salopp übersetzt bedeutet der Begriff so viel wie: Da funkt jemand dazwischen. Aber in diesem Podcast geht es um Soziale Arbeit, und deshalb sind die Zwischentöne wichtig – es steckt nämlich viel mehr hinter dem Begriff, als es auf den ersten Blick scheint. In dieser Episode graben sich Host Menno Labruyère und «Sozipedia»-Erfinder Martin Biebricher, Co-Leiter des Bachelorstudiengangs Soziale Arbeit an der ZHAW, tief in den Begriff der Intervention ein. Nicht immer bedeutet Intervention, dass ein machtvoller Eingriff in die Lebenswelt der Adressat:innen Sozialer Arbeit erfolgt, sondern es geht immer auch um das Schaffen tragfähiger Angebote sowie um das gemeinsame Handeln mit den Adressat:innen. Ausserdem beleuchten Menno Labruyère und Martin Biebricher die Rolle von Macht sowie die Notwendigkeit, Interventionen so zu gestalten, dass die Selbstbestimmung der Adressat:innen respektiert und sie zur Kooperation eingeladen werden. «sozipedia» ist eine Kolumne über Fachbegriffe auf Abwegen, die auch im Magazin «sozial» erscheint

Kleines Energiebudget, low-power KI und Security bilden ein Spannungsfeld. Der Vortrag erläutert diese Herausforderungen und zeigt einen Weg auf, wie das Systemdesign gelöst werden kann
A comprehensive model of LGBTQ+ youth suicide attempts to advance LGBTQ+-specific and -sensitive suicide prevention
No full textPecha Kucha PresentationLGBTQ+ youth are particularly vulnerable to suicide attempts, and existing models either lack consideration of broader living situations or fail to account for specificities of LGBTQ+ youth suicide attempts. Our Grounded Theory study investigated the dynamics, background, and subjective meaning of suicide attempts among LGBTQ+ youth, their experiences with care and support, and the role of SOGI (sexual orientation and gender identity). We conducted qualitative interviews with LGBTQ+ youth in Switzerland who had attempted suicide, and their social environment. The study identified three types to describe the role of SOGI in the suicide attempt process: SOGI-related factors as the main drivers; general factors as the primary reasons; and a combination of both. This empirical model provides a foundation for the development and advancement of LGBTQ+-specific and -sensitive suicide prevention strategies, as well as their coordination with and acknowledgement by general suicide prevention strategies and public health policy
Effects of tail states in Cs2AgBiBr6 double perovskites on solar cell performance : a temperature-dependent study of photovoltaic external quantum efficiency, open-circuit voltage, and luminescence
Get PDFCs2AgBiBr6 double perovskites have been investigated as a lead-free alternatives to lead-based perovskites. However, despite promising features such as high luminescence lifetimes, solar-cell efficiencies and the open-circuit voltage still remain too low. Various spectroscopic studies suggested multiple reasons such as a fast relaxation into localized self-trapped excitonic and polaronic states. However, it remains unclear to what extent the suggested processes are the culprit for the low device performance. In this study, full devices are characterized as a function of temperature, focusing on highly sensitive measurements of tail states. In the spectral response, a strongly-temperature-dependent Urbach energy is identified, indicative of high dynamic disorder. The current generated from the excitonic absorption becomes only limiting at lower temperatures with an activation energy of 0.15 eV. Analysis of light-, temperature- and voltage-dependent photoluminescence (PL) indicates that charge extraction correlates with PL quenching and PL does not originate from geminate pairs. The bandgap deduced from temperature-dependent open-circuit voltage is found at 2.0 eV, coinciding with the PL peak. In contrast, tail-state excitation leads to lower open-circuit voltage and luminescence that cannot be quenched with voltage. Having identified the importance of tail-state features, the methodology might assist in optimizing materials and devices for enhanced efficiency
