Universalist children’s services. From two-part to inclusive social infrastructure
(2024-01-11)
The scientific network “Universalist Children’s Services: From Two-Part to Inclusive Social Infrastructure,” funded by the German Research Foundation, comprises 20 researchers. Its purpose is to contribute to the development of a more inclusive design of the public children’s services system. To achieve this objective, the network integrates legal and educational perspectives in its analysis of the current structure of the children’s services system. The network’s starting point is the concept of universalist children’s ...

Drought threatens agroforestry landscapes and dryland livelihoods in a North African hotspot of environmental change
(2024-02-08)
Dryland agroforestry is often hailed as a nature-based solution for rural people’s water- and climate-related struggles, yet appraisals of traditional agroforestry practices and interventions in Maghreb countries are scant. In this study, we appraise whether and how agroforestry delivers as a solution to Moroccan farmers’ plight with drought. Through an analysis of landscape observations, 75 qualitative interviews, and six group discussions, we show that the region’s mountain residents risk losing their livelihoods ...

Analysis and Optimization of the Loss Distribution for a Two Stage AC/DC Power Supply
(2023-12-12)
This paper presents the analysis and optimization procedure of a two-stage bidirectional AC/DC power supply. The exemplary power supply consists of a silicon carbide based active front end and a dual active bridge DC/DC converter. It is designed to supply 600 V DC applications from universal low voltage AC grids with a power up to 6 kW. The paper includes the topology and design considerations, as well as an in-depth loss distribution analysis based on a validated loss model. The loss model is then utilized for an ...

Diskriminierungssensibles Coaching
(2023-11-20)
Diskriminierungen wirken sich als Teil der Arbeitswelt auf das gesamte Arbeitsleben aus. Dies hat negative Effekte für Organisationen und Individuen zur Folge. Coaching als Beratungsformat setzt an vielen arbeitsweltlichen Problem- und Fragestellungen an, daher stellt sich die Frage, inwiefern Coaching und Diskriminierungen in Verbindung stehen und sich gegenseitig beeinflussen. Dieser Beitrag arbeitet konzeptionell heraus, wie Coaching und Diskriminierungen zusammenhängen, warum die Reflexion und Berücksichtigung ...

Nicht sehen – nicht hören – nicht denken
(2023-12-07)
Der Beitrag setzt sich mit der Diskrepanz zwischen öffentlichem Bekenntnis zur Nachhaltigkeit auf der einen Seite und heftiger Abwehr gegen nachhaltiges Handeln auf der anderen Seite auseinander. Die Autor:innen beziehen sich auf die psychoanalytische Kulturtheorie und untersuchen ineinandergreifende Abwehrmechanismen die der kollektiven Ausblendung der Klimakrise dienen. Im zweiten Teil wird der Einfluss von Coaching mit Führungskräften und Entscheider:innen hinsichtlich Nachhaltigkeit reflektiert. Es wird dafür ...

Umweltverhalten mit Hand und Fuss(-abdruck)
(2023-11-30)
Die Klimaerwärmung stellt Gesellschaften ebenso wie Individuen vor bislang völlig unzureichend gelöste Probleme. Nullemissionen von Treibhausgasen sind zwar notwendig und werden politisch auch angestrebt, dennoch steigen sie immer schneller an. Um eine Transformation zur Nachhaltigkeit zu erreichen, ist ein sozialer Kipppunkt nötig. Bereits bekannte soziale Kipppunkte aus der jüngeren Vergangenheit sowie Hindernisse auf dem Weg zur Nachhaltigkeit werden vorgestellt. Der Fußabdruck bezeichnet den individuellen ...

Influence of Ethylene Oxide and Gamma Irradiation Sterilization Processes on the Properties of Poly-L-Lactic-Acid (PLLA) Materials
(2023-08-18)
In order to encourage the substitution of petrochemical polymers in medical technology with sustainable, bio-based materials, there is an urgent need for further investigations, especially data regarding their sterility performance. Within the scope of the investigations, selected material properties of poly-L-lactic-acid (PLLA), a specific type of poly(lactic-acid) (PLA), were analyzed before and after sterilization (using ethylene oxide or gamma irradiation) in order to investigate deviations in its chemical ...

Multi-Resolution Segmentation of Solar Photovoltaic Systems Using Deep Learning
(2023-12-11)
In the realm of solar photovoltaic system image segmentation, existing deep learning networks focus almost exclusively on single image sources both in terms of sensors used and image resolution. This often prevents the wide deployment of such networks. Our research introduces a novel approach to train a network on a diverse range of image data, spanning UAV, aerial, and satellite imagery at both native and aggregated resolutions of 0.1 m, 0.2 m, 0.3 m, 0.8 m, 1.6 m, and 3.2 m. Using extensive hyperparameter tuning, ...

Algorithm for fast evaluation of in-plane fiber orientation in reinforced plastics using light microscopy images
(2023-09-26)
Methods for evaluating the orientation of carbon fibers in reinforced plastics vary in complexity and are application specific. Here, we report an algorithm that quickly evaluates in-plane fiber orientation based on determining the correlation coefficient of adjacent regions in microscopy images. The result is not the fiber orientation of individual fibers, but the principal fiber orientation of small image areas. This method is applicable to large areas due to its low computation time and captures varying fiber ...

Embedding plural values in value chains to enhance sustainability in the management of cork oak landscapes
(2023-07-19)
Context
The management of Portuguese agroforestry landscapes is currently focused on specialised cork and cattle production. Sustainable landscape management is increasingly discussed as an effective option to foster the multifunctionality of these landscapes. Such management requires consideration of multiple values connected to the landscape and to the products stemming from it.
Objectives
The aim of this study is to (1) assess the importance of specific values related to cork and to the cork production ...
