Advancing science on the multiple connections between biodiversity, ecosystems and people
No full textThis Editorial of the International Journal of Biodiversity Science, Ecosystem Services & Management (IJBESM) marks the end of this Journal’s publications under Rudolf de Groot. He has been instrumental in bringing the concept of ecosystem services to the fore, through seminal publications, books, lectures, through founding and chairing the Ecosystem Services Partnership (ESP); and finally, through ‘adding the ecosystem services to IJBESM’. After almost 8 years as Editor-in-Chief, he has decided to step down and hand over to a next generation.In the final part of this co-written Editorial, Rudolf de Groot will look back one last time at some highlights of the past years, partly together with his editorial team. The first part of this Editorial introduces the new co-Editors in Chief and how they envision the future of the Journal. Berta Martín-López (Leuphana University of Lüneburg, Germany) and Alexander van Oudenhoven (Leiden University, Netherlands) have gladly accepted to take over as co-Editors in Chief of IJBESM. They are interdisciplinary scientists at the forefront of research on social-ecological systems, ecosystem services, ecosystem management and sustainability transformation. Both are heavily involved in the Intergovernmental science-policy Platform on Biodiversity and Ecosystem Services (IPBES) and both have been actively involved with this Journal for several years. While acknowledging and building on the achievements of the last couple of years, they suggest a way forward for publishing research on human–nature relationships.Conservation Biolog
Bayesian Maximum Entropy Ensemble Refinement
No full textThe principle of maximum entropy provides a canonical way to include measurement results into a thermodynamic ensemble. Observable features of a thermodynamic system, which are measured as averages over an ensemble are included into the partition function by using Lagrange multipliers. Applying this principle to the system’s energy leads to the well-known exponential form of the Boltzmann probability density. Here, we present a Bayesian approach to the estimation of maximum entropy parameters from nuclear Overhauser effect measurements in order to achieve a refined ensemble in molecular dynamics simulations. To achieve this goal, we leverage advances in the treatment of doubly intractable Bayesian inference problems by adaptive Markov Chain Monte Carlo methods. We illustrate the properties and viability of our method for alanine dipeptide as a simple model system and trp-cage as an example for a more complex peptide
Harmonisation of product notification to Poisons Centres in EU Member States.
No full textItem does not contain fulltextINTRODUCTION: In the European Union (EU), notification of product information by industry to poisons centres and/or competent authorities is a legal obligation for mixtures classified as hazardous. However, EU legislation does not specify the precise information needed for this product notification. As a consequence, varying requirements have been developed in different EU Member States. The European Commission (EC) carried out an assessment of whether harmonisation of product notification can be achieved. This manuscript provides an overview of the most important (discussion) points to reach harmonisation. COMPOSITION AND CONCENTRATION OF INGREDIENTS: Discussions have focused mainly on whether non-classified ingredients should be notified only above a concentration threshold and on the use of defined, narrow concentration ranges instead of exact concentrations for hazardous ingredients. ELECTRONIC DATA EXCHANGE FORMAT: All stakeholders agree to the development of an electronic data exchange format for product notification and identify the eXtensible Markup Language (XML) as the most appropriate format. EUROPEAN PRODUCT DATABASE: Instead of multiple notifications to national databases, the EC will analyse the benefits, feasibility and costs of a European product database to provide a centralised portal for companies to upload their product information. Poisons centres and competent authorities need to have access to this information. UNIQUE PRODUCT IDENTIFIER: A Unique Product Identifier (UPI) on the product label can unambiguously identify the product and its formula and links it to the corresponding notified product information. A procedure for the creation of a UPI by companies has already been proposed. PRODUCT CATEGORY SYSTEM: There is broad support for the development of a hierarchical product category system to facilitate statistical analyses and comparability of poisoning incidents in EU Member States. OUTLOOK: Following a 3-year assessment period, the EC concluded that harmonisation of product notification is an achievable goal. In order to draft an Annex to the CLP Regulation concerning this topic, a new working group with representatives of EU Member States, European Association of Poisons Centres and Clinical Toxicologists (EAPCCT) and other stakeholders will attempt to find consensus on harmonisation of product notification.01 februari 201

Activating household waste separation behaviour in high-rise Rotterdam: Capitalising on the moment of moving for stimulating behavioural change
No full textCurrently, the City of Rotterdam is far from achieving their ambitious 2020 goal of a 40% household waste separation rate. In 2017, their separation rate was only 28,4%. Household waste separation is important to enable the recycling of resources. For high-rise buildings, the challenge is the biggest: high-rise buildings produce an average of 150 kg more residual waste per year compared to low-rise buildings. The City of Rotterdam’s plans to build more high-rise buildings in the coming years makes it urgent to look for a solution. Separation at the source currently is more effective than mechanical post-consumer separation. However, the success of separation at the source depends entirely on the waste separation behaviour of high-rise residents. Therefore the main research question is: How to facilitate for high-rise residents the desired behaviour of waste separation at household level, in high-rise buildings?From human behaviour theory, behaviour can be explained as a combination of one’s motivation, ability, and opportunity. When one’s motivation is low, a low ability needs to be sufficient to trigger action. A change of environment can support a behaviour change. The many influencing factors for waste separation found in literature show the complexity of the behaviour. The factors are supported and complemented by interviews and generative research. Understanding high-rise residents’ mindset towards household waste separation, reveals four different groups of people: the Enthusiasts, the Potentials, the Skeptics and the Conservatives. The Potentials are closest to following the Enthusiasts in practising waste separation. However, they currently lack a (physical and mental) system for doing so. When considering starting this behaviour, the required effort for creating a system outweighs their medium level of motivation. The proposed solution is Schone start. Schone start supports high-rise residents with the creation of a waste separation habit in the first month after moving, by providing the means to set-up a system for waste separation. The mail delivery package contains a Waste guide, Waste map, small waste bin, medium waste bag, large waste box, stickers and suggestions for use. All essential information to start waste separation is actively provided and in accordance with the circular ambitions of the City of Rotterdam. Schone start is evaluated with six recently moved high-rise residents in Rotterdam. Generally Schone start is positively evaluated by the test participants regarding helpfulness with household waste separation. The Waste guide and Waste map were highly appreciated. The waste facilities were partially used, but can be optimised. The ease of disposal of the separated waste stays a critical boundary condition.To implement Schone start, its design should be optimised for appearance and size to maximise the percentage of citizens making use of the product. It is recommended to evaluate the long-term quantitative effect (the household waste separation rate) and qualitative effect (awareness of the household waste separation practice) of Schone start in a large scale pilot over six months. In this way, more insights can be gained regarding the potential impact of Schone start for different target groups and contexts.Integrated Product Desig

Do existing real-world data sources generate suitable evidence for the HTA of medical devices in Europe? Mapping and critical appraisal
No full textAim Technological and computational advancements offer new tools for the collection and analysis of real-world data (RWD). Considering the substantial effort and resources devoted to collecting RWD, a greater return would be achieved if real-world evidence (RWE) was effectively used to support Health Technology Assessment (HTA) and decision making on medical technologies. A useful question is: To what extent are RWD suitable for generating RWE? Methods We mapped existing RWD sources in Europe for three case studies: hip and knee arthroplasty, transcatheter aortic valve implantation (TAVI) and mitral valve repair (TMVR), and robotic surgery procedures. We provided a comprehensive assessment of their content and appropriateness for conducting the HTA of medical devices. The identification of RWD sources was performed combining a systematic search on PubMed with gray literature scoping, covering fifteen European countries. Results We identified seventy-one RWD sources on arthroplasties; ninety-five on TAVI and TMVR; and seventy-seven on robotic procedures. The number, content, and integrity of the sources varied dramatically across countries. Most sources included at least one health outcome (97.5%), with mortality and rehospitalization/reoperation the most common; 80% of sources included resource outcomes, with length of stay the most common, and comparators were available in almost 70% of sources. Conclusions RWD sources bear the potential for the HTA of medical devices. The main challenges are data accessibility, a lack of standardization of health and economic outcomes, and inadequate comparators. These findings are crucial to enabling the incorporation of RWD into decision making and represent a readily available tool for getting acquainted with existing information sources
