Die Konsortien der Nationale Forschungsdateninfrastruktur (NFDI) bieten eine Vielzahl von Services für das Forschungsdatenmanagement (FDM), die für Forschung, forschungsorientierte Lehre und Transfer an Hochschulen für angewandte Wissenschaften (HAW) von großer Bedeutung sind. Aufgrund institutioneller Besonderheiten stehen HAW jedoch vor spezifischen Herausforderungen bei der Implementierung von FDM-Strukturen. Ein zentraler Lösungsansatz ist die Entwicklung eines Serviceverzeichnisses, das eine gezielte Zuordnung der NFDI-Services zu den Fachbereichen und Bedarfen der Forschenden an HAW ermöglicht – der NFDI N(HAW)igator kann hierfür als beispielhafter Lösungsansatz dienen. Der Beitrag beleuchtet die Notwendigkeit einer klaren Service-Definition, die Bedeutung der Community-Beteiligung und die Herausforderungen bei der Aktualisierung und Pflege eines solchen Verzeichnisses. Es wird aufgezeigt, wie ein umfassendes Serviceverzeichnis zur effektiven Nutzung der NFDI-Angebote beitragen und die FDM Praxis an HAW stärken kann.
The paper focuses on developing an integrative methodology to evaluate environmental, economic, and social sustainability of alternative solution design options. Core approach is to extend the classic method of Quality Function Deployment (QFD) towards a holistic integrated model to overall evaluate the different aspects of all three pillars of sustainability (economy, ecology and social) across the product life cycle. The methods identify key aspects and allow users to consider and weigh different life cycle aspects in a overall scoring scheme.
In den letzten Jahren wurden Webseiten immer umfangreicher und der Einsatz von Open Source Web Frameworks ist mittlerweile ein integraler Bestandteil bei der Umsetzung von Webanwendungen. Welchen Einfluss diese Frameworks auf die Nachhaltigkeit von Webanwendungen haben, ist noch nicht ausreichend geklärt. Deshalb wird die Architektur einiger Open Source Web Frameworks untersucht und deren Auswirkungen auf den Energieverbrauch von Webanwendungen betrachtet. Mit einer empirischen Studie werden verschiedene Anwendungen umgesetzt und der Energieverbrauch ermittelt. Im Rahmen von Interviews werden die Ergebnisse der Studie in Unternehmen präsentiert und dabei untersucht, welche Bedeutung die Ergebnisse für die Webentwicklung haben. Es zeigt sich, dass sich die Auswahl eines Frameworks auf den Energieverbrauch auswirkt. Unternehmen in der Webentwicklung berücksichtigen diesen Aspekt aktuell noch nicht in ihren Projekten.

To investigate loudness biases in the lab, where outdoor sounds are perceived as being too loud if reproduced with physically accurate levels in the lab, a listening experiment was conducted, where thirty-one participants visited a street and listened to the environmental sounds for one minute. These sounds were also recorded using a dummy head. Afterwards, participants listened to the recording in a quiet laboratory and adjusted its level as they remembered it. About half of the sample did this immediately, the other half about 20 min after the recording, during which the performed another listening tests. Afterwards, previous experience with acoustics, musical sophistication and noise sensitivity were assessed. The results revealed a mean gain adjustment of 8.9 dB below the original. The data uploaded here comprises participants gain adjustment, the recording levels averaged other A) the entire recording and B) the first and last 7.5s or 15s, respecitvely and all questionnaire responses as well as aggregate scores for musical sophistication and noise sensitivity, as well as a binary categorization of the respondent into laymen and experienced, based on their previous experience with acoustics. For sociodemographic information, participants age, sex and educational degree are reported as well.

Laboratory experiments in psychoacoustical and soundscape research indicate that participants perceive a reproduction sound level lowered by 8-10 dB as more plausible than the original level. This bias supposedly roots in an adaptation of perceptual loudness scaling to the laboratory environment, that is overall quieter than urban outdoor soundscapes. To gain further insights into the nature of such loudness bias, we conducted a listening experiment in both field and laboratory using a within-subjects design. Thirty-one participants visited a street and listened to the environmental sounds for one minute, while these sounds were also recorded using a dummy head. Thereafter, they listened to the recording in a quiet laboratory nearby and adjusted its level as they remembered it. About half of the sample did this immediately, the other half about 20 minutes after the recording. Results confirm a bias towards lower levels with a mean of about 8.9 dB, regardless of the time between the recording and the reproduction in the laboratory. Also, participants with higher musical abilities tended to select higher, more accurate levels, whereas noise-sensitive participants deemed lower levels appropriate. Results suggest that the hypothesized adaptation of perceptual scaling to the laboratory happens immediately and is affected by individual factors.
