- In this article, we present a methodological framework that meets novel requirements emerging from upcoming types of accelerated and highly configurable neuromorphic hardware systems. We describe in detail a device with 45 million programmable and dynamic synapses that is currently under development, and we sketch the conceptual challenges that arise from taking this platform into operation. More specifically, we aim at the establishment of this neuromorphic system as a flexible and neuroscientifically valuable modeling tool that can be used by non-hardware experts. We consider various functional aspects to be crucial for this purpose, and we introduce a consistent workflow with detailed descriptions of all involved modules that implement the suggested steps: The integration of the hardware interface into the simulator-independent model description language PyNN; a fully automated translation between the PyNN domain and appropriate hardware configurations; an executable specification of the future neuromorphic system that can be seamlessly integrated into this biology-to-hardware mapping process as a test bench for all software layers and possible hardware design modifications; an evaluation scheme that deploys models from a dedicated benchmark library, compares the results generated by virtual or prototype hardware devices with reference software simulations and analyzes the differences. The integration of these components into one hardware-software workflow provides an ecosystem for ongoing preparative studies that support the hardware design process and represents the basis for the maturity of the model-to-hardware mapping software. The functionality and flexibility of the latter is proven with a variety of experimental results.

- To present a reduced version of the Housing Enabler, useful as a screening tool in practice contexts and in research, this study identifies the core items of the environmental component of the instrument, that is, the items most important in terms of the instrument's overall validity to measure accessibility problems. Utilizing cross-national data and interdisciplinary knowledge through an iterative process, a set of core items was identified. The environmental component of the reduced version comprises 61 items, compared to 188 in the original instrument. The rank correlation between the accessibility scores generated by the original and reduced versions was r ≥ .97 (p < .001). Based on comprehensive empirical research in three countries, the reduced version of the Housing Enabler is a time-efficient and valid screening instrument. It is a powerful tool for research and interventions focusing on housing accessibility problem identification.

- Purpose: Our purpose in this study was to explore relationships between aspects of objective and perceived housing in five European samples of very old adults, as well as to investigate whether cross-national comparable patterns exist. Design and Methods: We utilized data from the first wave of the ENABLE-AGE Survey Study. The five national samples totalled 1,918 individuals aged 75 to 89 years. Objective assessments of the home environment covered the number of environmental barriers as well as the magnitude of accessibility problems (an aspect of person-environment fit). To assess perceptions of housing, we used instruments on usability, meaning of home, and housing satisfaction. We also assessed housing-related control. Results: Overall, the results revealed that the magnitude of accessibility problems, rather than the number of physical environmental barriers, was associated with perceptions of activity-oriented aspects of housing. That is, very old people living in more accessible housing perceived their homes as more useful and meaningful in relation to their routines and everyday activities, and they were less dependent on external control in relation to their housing. The patterns of such relationships were similar in the five national samples. Implications: Objective and perceived aspects of housing have to be considered in order to understand the dynamics of aging in place, and the results can be used in practice contexts that target housing for senior citizens.
