    The importance of seed bank knowledge for the restoration of coastal plant communities - a case study of salt marshes and dune slacks at the Belgian coast

    Get PDF
    Knowledge on seed bank density and species composition is crucial for predicting the probability that target species will establish in the plant community on a restored site. A general overview of data available for plant species occurring in coastal plant communities showed that information on seed persistence is up to now very limited. The available data suggest that restoration of coastal plant communities cannot rely on the seed bank, except for annual species of salt marshes, and that the seed bank is to a large extent composed of species of nutrient rich habitats. This was confirmed by two case studies in dune slacks and salt marshes on the Belgian coast. Seed density in dune slacks was found to be relatively high, but the seed bank contained almost exclusively seeds of species of nutrient rich habitats, resulting in a very low similarity ratio between seed bank and vegetation. Germination from the seed bank would rather hamper the establishment of target species because competitive pressure imposed by fast growing species of nutrient rich habitats would increase. In salt marshes, the similarity between seed bank and vegetation was higher, because there is a higher contribution of typical salt marsh species in the seed bank, although not all target species are equally represented. To allow predictions of future species composition on restored sites, seed bank studies should be an essential part of each coastal restoration project

    A 'good faith' interpretation of the right to manifest religion? The diverging approaches of the European Court of Human Rights and the UN Human Rights Committee

    Get PDF
    The European Court of Human Rights (ECtHR) and UN Human Rights Committee have reached contradictory decisions in cases concerning the right to manifest religion. This discrepancy calls into question the universality of the right and is problematic from the perspective of legal certainty. Consequently, this article explores the extent to which the diverging decisions of these two bodies are compatible with a good faith interpretation of the right to manifest religion. A good faith interpretation of the right is identified by utilising the travaux prĂ©paratoires and subsequent interpretations. It is argued that by failing to scrutinise the necessity of restrictions and the role of secularism, the ECtHR has undermined this good faith interpretation and, in so doing, is not fulfilling its role as ‘the conscience of Europe’

    The possibility of recycling biodegradable waste materials (manure and waste from agricultural crops) into new proteins was investigated through experiments with various aquaticfood chains. The possibility of increasing the biomass yield through recuperation of the lost energy of thermal effluents was continually taken into consideration. The most promising production procedures which could lead to industrial applificatians are: a) the controlled mass production of pickling lobsters (Artemia) in "batch" or "flow through" systems using agricultural wastes, b). the nursery production of edible shell-fish (oysters, Paphia pullastra clams) using microscopic algae which were grown on manure. Units were designed of both types on a semi-industrial scale and were built on the Belgian coast. In conclusion it can also be mentioned that the mass production of water fleas (Daphnia) using manure and agricultural waste gave very encouraging results on a laboratory scale

    Face-to-face vs telephone pre-colonoscopy consultation in colorectal cancer screening; A randomised trial

    Get PDF
    Background: A pre-colonoscopy consultation in colorectal cancer (CRC) screening is necessary to assess a screenees general health status and to explain benefits and risks of screening. The first option allows for personal attention, whereas a telephone consultation does not require travelling. We hypothesised that a telephone consultation would lead to higher response and participation in CRC screening compared with a face-to-face consultation. Methods:A total of 6600 persons (50-75 years) were 1: 1 randomised for primary colonoscopy screening with a pre-colonoscopy consultation either face-to-face or by telephone. In both arms, we counted the number of invitees who attended a pre-colonoscopy consultation (response) and the number of those who subsequently attended colonoscopy (participation), relative to the number invited for screening. A questionnaire regarding satisfaction with the consultation and expected burden of the colonoscopy (scored on five-point rating scales) was sent to invitees. Besides, a questionnaire to assess the perceived burden of colonoscopy was sent to participants, 14 days after the procedure.Results:In all, 3302 invitees were allocated to the telephone group and 3298 to the face-to-face group, of which 794 (24%) attended a telephone consultation and 822 (25%) a face-to-face consultation (P=0.41). Subsequently, 674 (20%) participants in the telephone group and 752 (23%) in the face-to-face group attended colonoscopy (P=0.018). Invitees and responders in the telephone group expected the bowel preparation to be more painful than those in the face-to-face group while perceived burden scores for the full screening procedure were comparable. More subjects in the face-to-face group than in the telephone group were satisfied by the consultation in general: (99.8% vs 98.5%, P=0.014).Conclusion:Using a telephone rather than a face-to-face consultation in a population-based CRC colonoscopy screening progr

    Objectives: The aim of the study was to generate a comprehensive bank of systematic review (SR) reporting items to inform an update of the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) 2009 statement. Methods: We searched the Enhancing the QUAlity and Transparency Of health Research Network library in May 2019 to identify all reporting guidelines for SRs that were published after 2009, regardless of the scope of the guideline. We also conducted a selective review of four guidance manuals for SRs, three tools for assessing the risk of bias in SRs, six meta-research studies evaluating the reporting quality of SRs using a tailored checklist, and five reporting guidelines for other study designs. One author screened and selected sources for inclusion, extracted reporting guidance from sources, and mapped guidance against the PRISMA 2009 checklist items. Results: We included 60 sources providing guidance on reporting of SRs and meta-analyses. From these, we collated a list of 221 unique reporting items. Items were categorized into title (four items), abstract (10 items), introduction (12 items), methods (111 items), results (61 items), discussion (12 items), funding and conflicts of interest (four items), administrative information (three items), and data availability (four items). This exercise generated 175 reporting items that could be added to the guidance in the PRISMA 2009 statement. Conclusion: Generation of a comprehensive item bank through review and mapping of the literature facilitates identification of missing items and those needing modification, which may not otherwise be identified by the guideline development team or from other activities commonly used to develop reporting guidelines
