Baseline data on anthropogenic seafloor debris contamination in the year 2000 is provided for 24 submersible video transects at depths of 80–900 m, off the Dutch ABC-islands (Aruba, Bonaire, Curaçao), in the southeastern Caribbean Sea. In total, 202 objects were documented from a combined 21,184 m of transect, ranging from sandy lower island-slope to rocky upper island-slope habitat. Debris densities differed significantly with depth. Highest debris accumulation (0.459 items 100 m−2 or 4590 items per km2) occurred at depths of 300–600 m on more shallow-sloping (20–30°) sand and silt bottoms. The overall average debris density was 0.27 objects per 100 m2 (or 2700 items per km2), which is an order of magnitude higher than most other deepwater debris studies. What we describe may be representative for other small, populated, steep volcanic Caribbean islands. Food and beverage-related items were the single largest usage category identified (44% of objects; mostly glass beverage bottles).

Purpose: The aims of this study were to investigate how a variety of research methods is commonly employed to study technology and practitioner cognition. User-interface issues with infusion pumps were selected as a case because of its relevance to patient safety. Methods: Starting from a Cognitive Systems Engineering perspective, we developed an Impact Flow Diagram showing the relationship of computer technology, cognition, practitioner behavior, and system failure in the area of medical infusion devices. We subsequently conducted a systematic literature review on user-interface issues with infusion pumps, categorized the studies in terms of methods employed, and noted the usability problems found with particular methods. Next, we assigned usability problems and related methods to the levels in the Impact Flow Diagram. Results: Most study methods used to find user interface issues with infusion pumps focused on observable behavior rather than on how artifacts shape cognition and collaboration. A concerted and theorydriven application of these methods when testing infusion pumps is lacking in the literature. Detailed analysis of one case study provided an illustration of how to apply the Impact Flow Diagram, as well as how the scope of analysis may be broadened to include organizational and regulatory factors. Conclusion: Research methods to uncover use problems with technology may be used in many ways, with many different foci. We advocate the adoption of an Impact Flow Diagram perspective rather than merely focusing on usability issues in isolation. Truly advancing patient safety requires the systematic adoption of a systems perspective viewing people and technology as an ensemble, also in the design of medical device technology.
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.
In de automotive sector vindt veel onderzoek en ontwikkeling plaats op het gebied van autonome voertuigtechnologie. Dit resulteert in rijke open source software oplossingen voor besturing van robotvoertuigen. HAN heeft met haar Streetdrone voertuig reeds goede praktijkervaring met dergelijke software. Deze oplossingen richten zich op een Operational Design Domain dat uitgaat van de publieke verkeersinfrastructuur met daarbij de weggebruikers rondom het robotvoertuig. In de sectoren agrifood en smart industry is een groeiende behoefte aan automatisering van mobiele machinerie, versterkt door de actuele coronacrisis. Veel functionaliteit van bovengenoemde automotive software is inzetbaar voor mobiele robotica in deze sectoren. De toepassingen zijn enerzijds minder veeleisend - denk aan de meer gestructureerde omgeving, lagere snelheden en minder of geen ‘overige weggebruikers’ – en anderzijds heel specifiek als het gaat over routeplanning en (indoor) lokalisatie. Vanwege dit specifiek karakter is de bestaande software niet direct inzetbaar in deze sectoren. Het MKB in deze sectoren ervaart daarom een grote uitdaging om dergelijke complexe autonome functionaliteit beschikbaar te maken, zonder dat men kan voorbouwen een open, sectorspecifieke softwareoplossing. In Automotion willen de aangesloten partners vanuit bestaande kennis en ervaring tot een eerste integratie en demonstratie komen van een beschikbare automotive open source softwarebibliotheek, aangepast en specifiek ingezet op rijdende robots voor agrifood en smart industry, met focus ‘pickup and delivery’ scenario’s. Hierbij worden de aanpassingen - nieuwe en herschreven ‘boeken’ in de ‘bibliotheek’ - weer in open source gepubliceerd ter versterking van het MKB en het onderwijs. Parallel hieraan willen de partners ontdekken welke praktijkvragen uit dit proces voortvloeien en welke onderliggende kennislacunes in de toekomst moeten worden ingevuld. Via open workshops met uitnodigingen in diverse netwerken worden vele partijen uitgenodigd om gezamenlijk aan de hand van de opgedane ervaringen van gedachten te wisselen over actuele kennisvragen en mogelijke gezamenlijke toekomstige beantwoording daarvan.
The project is a field study for several diverse hotel chains, including individual properties operated under the Marriott brand, Postillion Hotels. Each brand has unique values, missions, and visions. Therefore, this integration will lead to the development of company-specific sustainability strategies and processes. The study will use the model of levers of control to provide such tailor-made solutions and determine if a generic approach can be developed to match a corporate sustainability strategy with a corporate strategy and develop a supporting management control system for operationalizing the sustainability strategy. Research question: How can a hotel brand formulate and implement a sustainability strategy with a supporting management control system that not only complies with the new CSRD (Corporate Sustainability Reporting Directive) legislation but also emphasizes the creation of substantial value in financial and ESG (Environmental, Social, and Governance) aspects, based on double materiality, in line with the organization's corporate values and beliefs? Objective The aim is to develop a validated method, including tools, that hotels can use to create a sustainability strategy in line with the CSRD guidelines. This strategy should create value for the organization, the environment, and society, while aligning with the hotel's values and beliefs. Merely being compliant with the CSRD is not enough for hotels. Instead, they should view the implementation of the CSRD as an opportunity to stand out in terms of sustainability. By creating value in areas such as environment, safety, and governance, or through the six capitals (financial, manufactured, intellectual, human, social and relationship, and natural) that align with the UN-SDGs, and explicitly taking both an inside-out and an outside in perspective (double materiality), hotels can significantly enhance their sustainability reputation.
