The challenges of model based policy advice
No full textIn policy consultation, communicating model results to administration and policy makers has always proven to be a challenge for scientists. Many of the relevant preconditions for effective and successful policy advice are aggravated when results are based on the simultaneous use of a multitude of different models. This paper identifies key issues – e.g., relations to administration; correct identification of prevailing objectives of all agents involved; ability to run scenarios ‘in time’ - and discusses strategies for successful communication based on the experiences of the vTI model network. Specific attention is paid to the issue of communicating ‘conflicting’ results of different models: while often seen as a source for scientific insight, such ‘inconsistencies’ have proven to be a major obstacle for acceptance in a non-academic institutional setting. The experiences, as well as the literature, point specifically to the importance of tight linkages between modellers and policy makers, and the need to abandon decisionist or technocratic approaches of policy advice in favour of pragmatic approaches stressing the bilateral nature of communication.model network, policy advice, Agricultural and Food Policy, Teaching/Communication/Extension/Profession,

Analyzing technology acceptance and perception of privacy in ambient assisted living for using sensor-based technologies
No full textPeople increasingly use various technologies that enable them to ease their everyday lives in different areas. Not only wearable devices are gaining ground, but also sensor-based ambient devices and systems are increasingly perceived as beneficial in supporting users. Especially older and/or frail persons can benefit from the so-called lifelogging technologies assisting the users in different activities and supporting their mobility and autonomy. This paper empirically investigates users' technology acceptance and privacy perceptions related to sensor-based applications implemented in private environments (i.e., passive infrared sensors for presence detection, humidity and temperature sensors for ambient monitoring, magnetic sensors for user-furniture interaction). For this purpose, we designed an online survey entitled "Acceptance and privacy perceptions of sensor-based lifelogging technologies"and collected data from N = 312 German adults. In terms of user acceptance, statistical analyses revealed that participants strongly agree on the benefits of such sensorbased ambient technologies, also perceiving these as useful and easy to use. Nevertheless, their intention to use the sensor-based applications was still rather limited. The evaluation of privacy perceptions showed that participants highly value their privacy and hence require a high degree of protection for their personal data. The potential users assessed the collection of data especially in the most intimate spaces of domestic environments, such as bathrooms and bedrooms, as critical. On the other hand, participants were also willing to provide complete data transparency in case of an acute risk to their health. Our results suggest that users' perceptions of personal privacy largely affect the acceptance and successful adoption of sensor-based lifelogging in home environments
Rising Anode-Free Lithium-Sulfur batteries
No full textAnode-free batteries (AFBs) represent a paradigm shift in battery architecture, eschewing conventional metal anodes in favor of current collectors (CCs). This innovative approach promises heightened energy densities, reduced manufacturing costs, and diminished environmental impact compared to traditional metal batteries. A particularly promising subset of AFBs are anode-free lithium-sulfur batteries (AFLSBs), which have garnered substantial attention due to their exceptional theoretical energy density, sulfur's abundance, and potential cost advantages. This mini-review encapsulates the recent studies in AFLSB research, elucidating key challenges and breakthroughs. The absence of a lithium (Li) metal anode mitigates safety concerns and maximizes cell energy density. However, successful Li plating on the CC necessitates a lithiophilic surface and a meticulously engineered solid electrolyte interphase (SEI). To surmount these obstacles, researchers are exploring a plethora of strategies, encompassing surface modifications, electrolyte additives, and cathode engineering. Promising results have been realized through metal coatings on CCs, utilization of 3D CCs, and incorporation of lithium polysulfide scavengers. Additionally, quasi-solid-state electrolytes offer enhanced safety and potentially augmented AFLSB performance. AFLSB research is a rapidly developing field with significant advancements being made. These breakthroughs hold the potential to usher in a new era of high-performance and sustainable energy storage solutions
