In order to design effective Persuasive Technology (PT) interventions, it is essential that designers understand the multitude of factors that lead to behavioral change, rather than guessing at a solution or imitating successful techniques without understanding why. The few available PT design frameworks solely distinguish behavioral determinants on an individual (micro) level (e.g., motivation), whereas successfully persuading a user is a multifaceted and complex task depending also on factors on a meso (e.g., available resources) and macro (e.g., social support and praise) level. We developed an analysis grid that enables PT designers to acknowledge the multifaceted character of determinants leading to behavioral change and select appropriate PT channels and strategies, preventing the failure of PT design. This analysis grid was validated in a case study in which we designed a PT intervention aimed at reporting minor crime incidents among citizens.
Studenten en bedrijfsleven roepen het hoger onderwijs op duurzaamheid prominent in het curriculum op te nemen. Dit artikel is een verkenning van de raakvlakken tussen economie en duurzaamheid met als doel thema’s te benoemen die in het curriculum van de opleidingen bedrijfseconomie en accountancy aan bod zouden kunnen komen. Er wordt eerst stilgestaan bij een beschrijving van de op ons afkomende problemen zoals klimaatverandering, grondstoffenschaarste en verlies aan biodiversiteit. Vervolgens wordt geschetst voor welke uitdagingen het bedrijfsleven staat en worden ontwikkelingen geschetst op macro-, meso- en microniveau. Afsluitend volgen suggesties voor op te nemen thema’s in het curriculum van de bedrijfseconomische en accountancy opleiding, zoals bijvoorbeeld een verdieping in de bestudering van verdelingsmechanismen (markt versus overheid), verbreding van het kostenbegrip, strategisch risicomanagement dat rekening houdt met duurzaamheid, duurzaamheidsverslaggeving en ketenmanagement. Het tot stand brengen van een duurzame economie vraagt daarnaast om buiten bestaande denkkaders te treden.
Background: Patient Reported Experience Measures are promoted to be used as an integrated measurement approach in which outcomes are used to improve individual care (micro level), organisational quality (meso level) and external justification (macro level). However, a deeper understanding of implementation issues of these measures is necessary. The narrative Patient Reported Experience Measure “Dit vind ik ervan!” (English “How I feel about it!”) is used in the Dutch disability care sector, but insight into its’ current use is lacking. We aimed to provide insight into experiences with the implementation and current ways of working with “Dit vind ik ervan!” as an integrated measurement strategy. A descriptive qualitative study was done at a disability care organisation. Data were collected by nine documentations, seven observations, 11 interviews and three focus groups. We applied deductive content analysis using the Consolidated Framework for Implementation Research as a framework. Results: Our analysis revealed facilitators and barriers for the implementation of “Dit vind ik ervan!”. We found most barriers at the micro level. Professionals and clients appreciated the measure’s narrative approach, but struggled to perform it with communication vulnerable clients. Some clients, professionals and team leaders were unfamiliar with the measure’s aim and benefit. On the meso level, implementation was done top-down, and the management’s vision using the measure as an integrated measurement approach was insufficiently shared throughout the organisation. Conclusions: Our study shows that Patient Reported Experience Measures have the potential to be used as an integrated measurement strategy. Yet, we found barriers at the micro level, which might have influenced using the measurement outcomes at the meso and macro level. Tailored implementation strategies, mostly focusing on designing and preparing the implementation on themicro level, need to be developed in co-creation with all stakeholders.
Micro and macro algae are a rich source of lipids, proteins and carbohydrates, but also of secondary metabolites like phytosterols. Phytosterols have important health effects such as prevention of cardiovascular diseases. Global phytosterol market size was estimated at USD 709.7 million in 2019 and is expected to grow with a CAGR of 8.7% until 2027. Growing adoption of healthy lifestyle has bolstered demand for nutraceutical products. This is expected to be a major factor driving demand for phytosterols. Residues from algae are found in algae farming and processing, are found as beachings and are pruning residues from underwater Giant Kelp forests. Large amounts of brown seaweed beaches in the province of Zeeland and are discarded as waste. Pruning residues from Giant Kelp Forests harvests for the Namibian coast provide large amounts of biomass. ALGOL project considers all these biomass residues as raw material for added value creation. The ALGOL feasibility project will develop and evaluate green technologies for phytosterol extraction from algae biomass in a biocascading approach. Fucosterol is chosen because of its high added value, whereas lipids, protein and carbohydrates are lower in value and will hence be evaluated in follow-up projects. ALGOL will develop subcritical water, supercritical CO2 with modifiers and ethanol extraction technologies and compare these with conventional petroleum-based extractions and asses its technical, economic and environmental feasibility. Prototype nutraceutical/cosmeceutical products will be developed to demonstrate possible applications with fucosterol. A network of Dutch and African partners will supply micro and macro algae biomass, evaluate developed technologies and will prototype products with it, which are relevant to their own business interests. ALGOL project will create added value by taking a biocascading approach where first high-interest components are processed into high added value products as nutraceutical or cosmeceutical.
Worldwide, coral reefs are rapidly declining due to increased sea water temperatures and other environmental stresses (Figure 1). To counter the extinction of major coral reef building species on the island of Bonaire, the non-profit organization Reef Renewal Foundation Bonaire is restoring degraded reef sites using corals that are grown in local nurseries. In these nurseries, corals are propagated on artificial trees using fragmentation. After 6-8 months of growth in the nursery, the corals are transplanted to degraded reef sites around the island. Over the years more than 21.000 corals have been outplanted to reef restoration sites in this way. These corals show high survivorship under natural reef conditions but remain under threat by environmental disturbances, such as increased water temperatures, diseases, and competition with macroalgae. A promising intervention to increase reef persistence and resilience is to manipulate the coral-associated microbiome. At present, the composition of the microbiome in nursery-reared and outplanted corals on Bonaire is unknown. The aim of the current project is to identify and isolate naturally occurring beneficial bacteria that may stimulate the resilience of these corals. Our key objectives are: 1) to assess the presence of functionally beneficial bacteria in corals in nursery and restoration sites on Bonaire using metagenomic screening. 2) to design culture strategies to isolate these functionally beneficial bacteria. In the future, a selection of these beneficial bacteria can be applied to the corals to increase their resilience against environmental disturbances.
The seaweed aquaculture sector, aimed at cultivation of macroalgal biomass to be converted into commercial applications, can be placed within a sustainable and circular economy framework. This bio-based sector has the potential to aid the European Union meet multiple EU Bioeconomy Strategy, EU Green Deal and Blue Growth Strategy objectives. Seaweeds play a crucial ecological role within the marine environment and provide several ecosystem services, from the take up of excess nutrients from surrounding seawater to oxygen production and potentially carbon sequestration. Sea lettuce, Ulva spp., is a green seaweed, growing wild in the Atlantic Ocean and North Sea. Sea lettuce has a high nutritional value and is a promising source for food, animal feed, cosmetics and more. Sea lettuce, when produced in controlled conditions like aquaculture, can supplement our diet with healthy and safe proteins, fibres and vitamins. However, at this moment, Sea lettuce is hardly exploited as resource because of its unfamiliarity but also lack of knowledge about its growth cycle, its interaction with microbiota and eventually, possible applications. Even, it is unknown which Ulva species are available for aquaculture (algaculture) and how these species can contribute to a sustainable aquaculture biomass production. The AQULVA project aims to investigate which Ulva species are available in the North Sea and Wadden Sea which can be utilised in onshore aquaculture production. Modern genomic, microbiomic and metabolomic profiling techniques alongside ecophysiological production research must reveal suitable Ulva selections with high nutritional value for sustainable onshore biomass production. Selected Ulva spp lines will be used for production of healthy and safe foods, anti-aging cosmetics and added value animal feed supplements for dairy farming. This applied research is in cooperation with a network of SME’s, Research Institutes and Universities of Applied Science and is liaised with EU initiatives like the EU-COST action “SeaWheat”.
