Abstract Background Although family photos are often used in the psychosocial care for people with dementia, little is known about the use and efectiveness of generic photos. This systematic literature review explored psychosocial interventions using generic photos for people with dementia, and the efects they have on their social interaction and/or mood and/or quality of life. In addition, it was investigated whether these interventions made use of technol‑ ogy in its implementation. Methods A systematic search on the following databases was performed: PubMed, Embase, APA PsychInfo, Cinahl, Web of Science, Scopus and Cochrane Central. Inclusion and exclusion criteria were based on the PICO model (Popu‑ lation, Intervention, Comparison, Outcome), and quality assessment was undertaken using the Weight of Evidence Framework. Narrative synthesis was undertaken to summarize study characteristics- settings and designs, type of psy‑ chosocial interventions identifed, type of photos and technology used, outcome measures, and results. Results A total of 2,035 results were found, however after title, abstract and full-text screening, a total of 8 studies were included. The most common psychosocial intervention using generic photos was found to be reminiscence therapy, followed by art-viewing activities. In studies that used technology, it was reported that viewing digitalized photos were either similar or better to conventional printed photos. Despite photos being generic, it was found that generic photos could still hold personal signifcance to the person with dementia. Some positive and signifcant efects were found for the outcomes social interaction, mood and quality of life, though no study evaluated all three outcomes. Two studies were rated as having high overall quality, 4 were rated as fair, and 2 studies had a low quality assessment rating. Conclusion Studies found using generic photos were limited, showing varying outcomes and methodological quality. Firm conclusions on the efectiveness of interventions using generic photos are not possible. However, the use of generic photos in psychosocial interventions is a promising area for future research. Researchers should consider studies with better methodological quality and larger samples; and qualitative studies where the intention is to get better insight into successful implementation and impact mechanisms of such psychosocial interventions.

Since the Like-button was introduced in 2009 by Facebook, its use increased rapidly. Liking became an important part of our daily routines on the internet since we are able to like almost any creative expression, such as photos and videos. Little is known about the effects of liking (and disliking) on these creative expressions. This paper investigates how the (dis)liking feature influences creativity. We conducted an experiment with a photo-application for mobile phones and provided different combinations of liking and disliking to two research groups and a control group. Our findings suggest thatproviding a liking feature is beneficial to creativity in terms of the production of creative content and results in higher amounts of photos. Providing a disliking feature as well is beneficial to creativity in terms of quality and results in higher rates for the photos.

Critical reflection, addressing students’ attitude, beliefs and values related to pressing topics in the world, plays a crucial role in developing ethical sensitiveness and critical design literacy in design education. Critical reflection is provoked by discussing self-made photos, as is demonstrated in the research method Photovoice. This paper considers Photovoice in design education for its ability to foster learning through self-guided critical reflective interactions with peers based on self-made photos. Research on how to support this is lacking. This paper addresses this gap by studying students engaging in self-guided Photovoice assignments. Results consist of adapted steps for Photovoice in education and illustrate potential as well as boundaries of self-guided Photovoice through students’ quotes and photomaps. Also, five frames of interpretation, suggested by students engaged in self-guided Photovoice, contribute to previous knowledge and may inspire the design education community to start experimenting with Photovoice in course work. The final aim is to support students in critical reflection, a crucial skill for responsible design professionals.

Horticulture crops and plants use only a limited part of the solar spectrum for their growth, the photosynthetically active radiation (PAR); even within PAR, different spectral regions have different functionality for plant growth, and so different light spectra are used to influence different properties of the plant, such as leaves, fruiting, longer stems and other plant properties. Artificial lighting, typically with LEDs, has been used to provide these specified spectra per plant, defined by their light recipe. This light is called steering light. While the natural sunlight provides a much more sustainable and abundant form of energy, however, the solar spectrum is not tuned towards specific plant needs. In this project, we capitalize on recent breakthroughs in nanoscience to optimally shape the solar spectrum, and produce a spectrally selective steering light, i.e. convert the energy of the entire solar spectrum into a spectrum most useful for agriculture and plant growth to utilize the sustainable solar energy to its fullest, and save on artificial lighting and electricity. We will take advantage of the developed light recipes and create a sustainable alternative to LED steering light, using nanomaterials to optimally shape the natural sunlight spectrum, while maintaining the increased yields. As a proof of concept, we are targeting the compactness of ornamental plants and seek to steer the plants’ growth to reduce leaf extension and thus be more valuable. To realize this project the Peter Schall group at the UvA leads this effort together with the university spinout, SolarFoil, whose expertise lies in the development of spectral conversion layers for horticulture. Renolit - a plastic manufacturer and Chemtrix, expert in flow synthesis, provide expertise and technical support to scale the foil, while Ludvig-Svensson, a pioneer in greenhouse climate screens, provides the desired light specifications and tests the foil in a controlled setting.
Carbon dioxide (CO2) is the final waste product for all carbon-containing products. Its reuse will partly mitigate climate change and, in addition, provide a valuable feedstock for fuels and chemicals. Zuyd University of Applied Sciences (ZUYD), Innosyn B.V., and Chemtrix B.V. will develop a flow reactor for photochemical reactions with gases conducted at high pressure. This reactor is the necessary first development towards artificial photosynthesis: the connection of hydrogen (H2) to the ultimate waste product CO2 to store energy in a chemical bond, in order to produce so-called solar fuels and C1-chemicals/products. With an increasing amount of renewables in the energy system, energy storage becomes increasingly important to continuously match supply and demand. In a cooperation between three ZUYD research groups with Chemtrix B.V. and Innosyn B.V., multiple cost-efficient reactor designs for this flow reactor will be analyzed and two designs will be selected to be implemented by small extensions of existing equipment. Simultaneously, two appropriate test re-actions involving a gas (E-Z isomerization followed by hydrogenation) and with a CO2 analogue (a hydrogenation of a carboxylic acid) will be developed to be conducted in the reactor when the con-struction has been finished. We aim to disseminate the new capabilities developed in this KIEM proposal by the project partners with respect to the new reactors to several selected stakeholders. Furthermore, to expand the project several options (SIA-RAAK and H2020 grants) will be explored.
In this project, Photons in Focus, researchers from The Hague University of Applied Sciences will work together with the company Photosynthetic to fabricate high-quality microlenses that will optimally focus light onto microscopic light detectors. Specifically, the microlenses will be designed to focus light onto superconducting nanowire single-photon detectors (SNSPDs) from the company Single Quantum. SNSPDs are cryogenic single-photon detectors with photon detection efficiencies up to 99% and timing resolutions down to 15 picosecond. Recently, Single Quantum has been developing arrays of SNSPDs for free-space biomedical imaging and deep space communications. The photon detection efficiency of these arrays is suboptimal, because 15-20% of the light falls onto nonsensitive areas. In Photons in Focus, fabrication of two types of microstructures will be explored for optimally focusing light onto these SNSPDs and improving the photon detection efficiency. First, 3-dimensional microlenses will be created at Photosynthetic using their method of dual-wavelength volumetric microlithography. Second, phase-reversal Fresnel zone plates will be fabricated using standard 2-dimensional photolithography at The Hague University of Applied Sciences. Both types of microstructures will be tested for their focusing properties and potential optical losses, and their ability to enhance to photon detection efficiency of SNSPDs in cryogenic conditions.
