Opname van ijzer onder invloed van biostimulanten in een circulaire paprikateelt

Een proef met biostimulanten om de opname van ijzer in een organisch teeltsysteem met circulaire meststoffen te bevorderen is uitgevoerd voor het Fieldlab circulaire meststoffen. De proef heeft aangetoond dat ijzerchelaat niet eenvoudig te vervangen is door ijzersulfaat en biostimulanten. De gebruikte middelen, die niet allen specifiek voor deze toepassing zijn ontwikkeld, konden zich niet voldoende vestigen onder de omstandigheden van deze paprikateelt op substraat. Meer onderzoek is nodig, niet alleen naar de keuze, maar ook naar de toepassingswijze en aanpassing aan het teeltsysteem. Na training van de AI met data uit de proef kunnen de Vivent biosensoren ijzerstress vroegtijdig signaleren. Dit biedt voor zowel onderzoek als praktijk mogelijkheden om de ijzerstatus van de plant te volgen. De beschikbaarheid in het wortelmilieu van ijzer in minerale vorm, is in een teeltsysteem zonder ijzerchelaat geen maat voor de opname. In combinatie met grote verschillen in ijzergebrek binnen de behandelingen biedt dit perspectief voor vervolgonderzoek in het vervolg van het project.

Sanitary systems

Global society is confronted with various challenges: climate change should be mitigated, and society should adapt to the impacts of climate change, resources will become scarcer and hence resources should be used more efficiently and recovered after use, the growing world population and its growing wealth create unprecedented emissions of pollutants, threatening public health, wildlife and biodiversity. This paper provides an overview of the challenges and risks for sewage systems, next to some opportunities and chances that these developments pose. Some of the challenges are emerging from climate change and resource scarcity, others come from the challenges emerging from stricter regulation of emissions. It also presents risks and threats from within the system, next to external influences which may affect the surroundings of the sewage systems. It finally reflects on barriers to respond to these challenges. http://dx.doi.org/10.13044/j.sdewes.d6.0231 LinkedIn: https://www.linkedin.com/in/sabineeijlander/ https://www.linkedin.com/in/karel-mulder-163aa96/

Learning to question the status quo. Critical thinking, citizenschip education and Bildung in vocational education

Educational policies in the Netherlands reveal that the current mainstream participatory approach to citizenship education jeopardises students’ autonomy. Especially in Dutch post-secondary vocational education, citizenship education has been shown to be mainly aimed at socialization: initiating students into tradition, internalising rules, societal norms and values. This article reports on the findings of a research project, which is grounded in the assumption that integrating Bildung, citizenship education and critical thinking is a promising way to grapple with the perceived overemphasis on socialization strategies. We justify the interrelationship of critical thinking, Bildung, citizenship education, and professional training from two perspectives – historical and contemporary. It is only by combining these concepts, we contend, that educational professionals can create teaching materials more geared to developing autonomy, and prepare students in vocational training to navigate the political and societal dilemma’s on the work floor. Furthermore, we also clarify our perspective by offering three educational principles, used in our project to guide the design of teaching materials, that form a context for integrating citizenship, critical thinking, and Bildung in vocational education. A practical illustration is subsequently discussed.

The golden rules of rewilding

This article aims to supplement the three “golden rules” of rewilding – or three Cs – the Cores, Carnivores, and Corridors – by a fourth C – Compassion, in discussing the case of Oostvaardeplassen in The Netherlands. The cores refer to large, strictly protected ecologically intact areas, carnivores refer to natural predators, and corridors connect passages for fauna movements. We propose a fourth requirement: Compassion. This fourth C would ensure that any active (re)introduction must be in the interests of the individual animals involved. This article briefly explains the history of the Oostvaardeplassen project and leads into a discussion of the scientific (biological requirements of the species, area, and species fit, etc. ) and ethical (animal welfare, ecocentrism, etc.) constraints and opportunities for rewilding. All four Cs, we argue, are absent from Oostvaardeplassen, which can be considered an example of how rewilding should not be undertaken. Against this background, we propose an alternative way forward. https://www.ecos.org.uk/ecos-406-the-golden-rules-of-rewilding-examining-the-case-of-oostvaardersplassen/ LinkedIn: https://www.linkedin.com/in/helenkopnina/

The impact of shared decision-making in perinatal care

Introduction: Shared decision-making is considered to be a key aspect of woman-centered care and a strategy to improve communication, respect, and satisfaction. This scoping review identified studies that used a shared decision-making support strategy as the primary intervention in the context of perinatal care. Methods: A literature search of PubMed, CINAHL, Cochrane Library, PsycINFO, and SCOPUS databases was completed for English-language studies conducted from January 2000 through November 2019 that examined the impact of a shared decision-making support strategy on a perinatal decision (such as choice of mode of birth after prior cesarean birth). Studies that only examined the use of a decision aid were excluded. Nine studies met inclusion criteria and were examined for the nature of the shared decision-making intervention as well as outcome measures such as decisional evaluation, including decisional conflict, decisional regret, and certainty. Results: The 9 included studies were heterogeneous with regard to shared decision-making interventions and measured outcomes and were performed in different countries and in a variety of perinatal situations, such as women facing the choice of mode of birth after prior cesarean birth. The impact of a shared decision-making intervention on women’s perception of shared decision-making and on their experiences of the decision-making process were mixed. There may be a decrease in decisional conflict and regret related to feeling informed, but no change in decisional certainty. Discussion: Despite the call to increase the use of shared decision-making in perinatal care, there are few studies that have examined the effects of a shared decision-making support strategy. Further studies that include antepartum and intrapartum settings, which include common perinatal decisions such as induction of labor, are needed. In addition, clear guidance and strategies for successfully integrating shared decision-making and practice recommendations would help women and health care providers navigate these complex decisions.

Writing the Self and Bereavement

That expressive writing can be a beneficial response to trauma or grief is well-established in the literature. Grief research also shows that the majority of people are resilient in the face of the death of loved ones. That said, traditional rituals around loss are no longer ubiquitous, well-known phase models of bereavement are contested, and ‘unfinished business’ can create difficulties in the face of loss. Increasingly, bereavement scholars speak of a need for individuals in western society to make meaning of their own grief through narrative construction, though little is said about what constitutes a beneficial story. The author takes an autoethnographic approach to write and reflect on her spouse’s illness and death and explores through a multi-voiced expressive dialogue a personal issue around her bereavement. In an analysis of her writing, using Dialogical Self Theory, she identifies markers which may be indicative of the development of a beneficially constructed narrative. The model of writing-for-transformation is used to describe the overall intent of the process, while the dialogical markers show how progress may be identified.

Final market system maps - assessments of barriers to WATERMINING technologies and how to clear these

The WATERMINING project aims to bring solutions to improve the circularity of water treatment and the resulting by-products of these processes. Achieving a deep understanding of the barriers potentially hindering the development of circular water solutions is crucial to design policies that enable the deployment of these techniques. To do this, the WATERMINING project organizes Communities of Practice (CoPs), where stakeholders from the WATERMINING case study projects analysed these market barriers and proposal (policy) measures to clear these.CoPs in the case studies of Lampedusa in Italy and Almería in Spain focused on sea water desalination. The case studies of Faro-Olhão in Portugal, Larnaca in Cyprus and La Llagosta in Spain have been discussed by CoP stakeholders in terms of barriers in circular urban wastewater treatment. The CoP in the Netherlands focused on circular industrial waste water treatment at the Westlake plant at Rotterdam. The barriers defined by the stakeholders in the CoPs were discussed by the WATERMINING partners at the consortium meeting in Palermo (Italy, September 2022), and presented at the WATERMINING Market and Policy workshop in Brussels (Belgium, February 2023).Addressing the three above-mentioned categories of circular water solutions, common barriers identified across all WATERMINING’s case studies are the following. First, stakeholders report a lack of incentives to implement circular solutions, as mainstream linear practices are generally cheaper.This could be addressed by de-encouraging linear techniques by making the disposal of their byproducts (such as brine) more expensive. Another solution could be to provide added value to circular solutions through the monetization of their additional products and services. Subsidies can support in lowering production costs or prices of materials recovered from sea- and wastewater treatment to level the playing field with conventionaly derived material.Another commonly mentioned barrier is the difficulty to introduce products obtained from circular water treatment in the market, both because of a lack of public acceptance and legal constraints stemming from products being regarded as waste. Information campaigns and the revision of current regulatory frameworks to allow these products entering the market would expand the revenue sources from these techniques and improve the circularity of the system. Standardising the circular water treatment technologies in the market could support this, whereby best available techniques reference documents of the EU (BREFs) could be an effective instrument, especially when tapping into an ongoing BREF writing or updating process.Across the case studies and replication studies it has been mentioned that current legislation in case study countries exclude ‘watermined’ products from food and/or other applications. Criteria for endof-waste status of ‘watermined’ products, which would determine whether a product, such as Kaumera which is produced from urban wastewater treatment, is eligible as a fertiliser in agriculture, are usually determined at the level of the EU, but Member States could interpret these more stringently (Member State-level criteria cannot be weaker than the EU-level ones). In this respect it has been recommended to enhance knowledge exchange across Member States, e.g., by creating anEU-based unit (or competencies within an existing unit) to promote cooperation among EU Member States and regional authorities concerning the production, sale and use of products recovered from wastewater treatment.Another common perception stakeholders report is the widespread conservatism in the water sector. Water treatment actors traditionally have a focus on purifying water and supplying this to the market. Generating products from waste streams is often something that market actors are less familiar with. Among other solutions, the ‘Dutch model’ has been recommended as a way to create national centres for the development of knowledge and technology for water management, which would serve as an R&D accelerator.

Understanding how educators at the workplace reach judgements when assessing students' professional performance

Paperbijdrage conferentie EARLI SIG 14, 11-14 september 2018, Genève Although professional performance at the workplace is essential in VET, little is known about what educators do when assessing students’ performance. This study aims to explore how workplace educators inform their judgements of students’ performance by looking at strategies and potentially influencing factors.

Multilevel boundary crossing

Symposiumbijdrage conferentie EARLI SIG 14, 11-14 september 2018, Genève Learning across the contexts of school and the workplace is highly relevant to the VET-sector. This contribution analyses these cross-contextual learning processes with three key issues in mind: (1) guidance by vocational educators, (2) assessment of students’ development and (3) design of VET-learning environments. Guidance, assessment and overarching VET-curriculum designs form the basis for constructive alignment as an approach to optimize conditions for high quality cross-contextual learning processes. We used the theoretical framework of boundary crossing to clarify the complex, multilevel nature of these key issues.
