Crises appear to be occurring with increased frequency, whether provoked directly by human actions or through indirect causes such as resource scarcity or natural disasters. Crisis management strategies are frequently implemented with the aim of mitigating the immediate impacts of these crises. Nevertheless, it is critical to also consider the long-term consequences of such strategies. This study investigates both the short- and long-term effects of various crisis management strategies during a financial crisis in relation to the energy transition. An agent-based model of the German electricity sector is developed to analyze the effects of different strategies. The findings suggest that a reduction in electricity demand by 10% achieves the most favorable outcomes, decreasing short-term electricity costs by 11% and long-term carbon dioxide emissions by 9%.

As design thinking becomes more and more important in higher education, we need to think about ways to enable educators and students to learn about the concepts and apply them to their own projects. One approach is to create hybrid learning spaces with tools that support design thinking and offer affordances for the various methods, ways of working and thinking. Hybridity dissolves existing dichotomies such as physical-digital, formal-informal, learning-teaching and individual-collective. This article introduces design principles and patterns to develop such spaces for university campuses. We will describe how we identified, applied and tested them. Based on these findings we can provide recommendations for planning new hybrid spaces for design thinking at other universities.

Informal social networks and especially advice networks are a key subject of organizational sociological research. The formation of these networks has so far been explained on the basis of universal tie-formation mechanisms. However, recent conceptual contributions suggest that tie formation practices follow cultural rules that may vary across social contexts. In our paper, we substantiate this argument empirically. Based on rich qualitative data, we compare advice tie formation (a) between two entrepreneurial communities and (b) between three research and development departments of large enterprises. We show that both impact and configuration of tie formation mechanisms systematically differ between comparable contexts. Building on our findings, we finally formulate propositions describing which advice network structures can be expected in specific cultures.

As part of the energy transition, near-Zero-Energy-Buildings use electric systems that reduce emissions and consumption. Nevertheless, the increased use of such systems comes with the E-waste challenge. Circular Economy concepts try to make more efficient use of these materials, but sustainable evaluations mainly focus on energy and emissions. The developed automated text analysis tool quantifies the appearance of circularity concepts in open-access literature about different stages of production, use, and end-of-life for heat pumps, Lithium-Ion batteries, photovoltaic modules, and inverters. The energy focus is corroborated in different amounts depending on the component and stage, and when circularity concepts appear, they are centred on waste and recycling. Numerical variables to model environmental impact available in open-access literature are limited, generalised, or present in a wide range. Access to product environmental specifications should be encouraged to ensure that energy transition is sustainable in all its dimensions.

This paper presents a method for dynamically controlling the gaze movement of patients during ophthalmic examinations, specifically using infrared funduscopy and Optical Coherence Tomography (OCT) to gather retinal information essential for glaucoma screenings. By using the patient's natural eye movements, this system eliminates the need for traditional precise scanning mirrors used in conventional OCT devices, which typically direct the OCT laser beam across the retina to produce A-scans. In this approach, the OCT laser beam remains fixed while the patient is guided to follow a predetermined pattern on a display with their eyes. This method effectively uses the patient’s eye movements to replace the functionality of scanning mirrors. By tracking the position of the eye in real time, the system ensures that the specific areas of the retina are captured. This technique not only provides a cost-effective alternative to traditional OCT systems but also enhances patient comfort by involving them actively in the process, reducing the need to fixate on a single point. During the examination, the system evaluates each measurement point, and the scan patterns can be adjusted if necessary to ensure comprehensive diagnostic data acquisition. The resulting positions are assigned to the OCT A-scans. This allows the optic nerve B-scans typical for glaucoma examinations to be created in the evaluation. The system is characterized by the fact that it enables flexible adjustments to the imaging patterns in real-time, based on which areas of the eye have already been captured and which still require examination. The setup mainly uses commercially available components to create a cost-effective alternative to conventional, often price-intensive diagnostic devices. This method has the potential to be important not only for the improved diagnosis and monitoring of eye diseases, including glaucoma, but also offers prospects for wider application in preventive eye health care.
