The European Commission White Paper on adaptation: appraising its strategic success as an instrument of soft law

The European Union took its first strategic step on the topic of climate adaptation in 2009 with publication of a White Paper on Adaptation. Since its publication, many researchers and analysts have criticized the White Paper for its lack of concrete and enforceable actions. In this paper, we analyse the White Paper as an instrument of soft law. First, we provide background on the theory of soft law, its terms of applicability, and the standards by which to judge its success. Second, we analyse the content and context of the White Paper according to soft law principles. We find that the conditions under which the White Paper was adopted were exactly those suited to a soft law approach and highly determined by the European multi-level governance context. As such, the White Paper has managed to achieve several of the common objectives of soft law in particular in setting up processes allowing information-sharing and subsidiarity. However it has failed to achieve several others especially in fostering the commitment of the states, and in moving the European Union in the direction of binding regulation. Further strategy development will be required to fix these deficiencies.     

Role of the second-trimester ‘genetic sonogram’ for Down syndrome screen in the era of first-trimester screening and noninvasive prenatal testing

Ultrasonography for the screening of Down syndrome was first introduced about 25 years ago. Different combinations of markers detectable at second-trimester ultrasonography have been proposed under the banner of ‘genetic sonogram’. In recent years, several developments in first-trimester screening and the recent introduction of noninvasive prenatal testing for aneuploidy screening have had important implications for the prevalence of these conditions in the second-trimester and the screening performance of a genetic sonogram. Several second-trimester sonographic markers for Down syndrome have been reported; meta-analysis has shown that the most powerful predictors are mild ventriculomegaly, increased nuchal fold, hyperechoic bowel, and absent or hypoplastic nasal bone. Whereas use of individual markers should be discouraged and scoring systems of multiple markers are now obsolete, use of combined likelihood ratio and logistic regression analysis formulae provides better accuracy. However, there is significant heterogeneity in results among studies. Despite such limitations, the genetic sonogram will continue to have a place in prenatal screening, particularly in twin and higher-order multiple pregnancies, in countries with limited access to the most recent genetic screening tests, in cases with borderline results at maternal serum screening tests, and as noninvasive supplementary test for high-risk women reluctant to undergo invasive diagnostic testing. © 2014 John Wiley & Sons, Ltd.     

Game theory approach to the analysis of inter-plant water integration in an eco-industrial park

Industrial water conservation is an important adaptation to the effects of climate change. In addition to water conservation within individual plants, wastewater can be reused/recycled among different companies through inter-plant water integration (IPWI) schemes. Such schemes are based on the concept of industrial ecology and industrial symbiosis, and can be used to achieve greater water savings than when water conservation is implemented in individual companies separately. However, in IPWI, each participating company seeks to maximise its own benefits. In the absence of centralised authority dictating the terms of water integration schemes, conventional modelling techniques are not appropriate. This paper shows how a game theory-based approach can be used to analyse the interaction of participating companies in an eco-industrial park seeking to develop an IPWI scheme.     

Should Scientific Research Involving Decapod Crustaceans Require Ethical Review?

Decapod crustaceans are faceless animals with five pairs of legs, an external skeleton and multiple nerve centres (ganglia) rather than a single brain (as in vertebrates). They include common seafood species such as crayfish, crabs, lobsters, prawns and shrimp. These characteristics make them difficult to empathise with and consequently legal protection of decapods ranges from strong (Norway and New Zealand), through circumstantial (Australia and Italy) to non-existent (in many other countries). Whether they are capable of experiencing pain depends on definitions and the requirement for absolute proof of an inherently subjective psychological experience. Yet like other animals, decapods fulfil neuroanatomical, pharmacological and behavioural criteria that are consistent with a pain response. Whether they experience stress, harm and distress is less controversial because these conditions are more measurable than the pain response. To balance animal welfare concerns with scientific merit whilst providing confidence for the growing public awareness of crustacean welfare, use of decapod crustaceans in research should require ethical review.     

Effect of inoculum to substrate ratio (I/S) on municipal solid waste anaerobic degradation kinetics and potential

The goal of this study is to evaluate the impact of the inoculum to substrate ratio (I/S) on the anaerobic degradation potential of municipal solid waste (MSW). Reconstituted MSW samples were thus incubated under batch anaerobic conditions and inoculated with an increasing amount of inoculum originating from a mesophilic sludge digester. I/S tested values were 0 (no inoculum added), 0.015, 0.03, 0.06, 0.12, 0.25, 1, 2 and 4 (gVM_inoculum/gVM_waste). The results indicate that the apparent maximal rate of dissolved organic carbon accumulation is reached at I/S = 0.12. Under this level, the hydrolysis process is limited by the concentration of biomass and can thus be described as first order kinetics phenomena with respect to biomass for I/S ratios below 0.12. The maximum methane production rate and the minimal latency are reached at a ratio of 2. In addition to that, both methane signature and ARISA show a shift in the methanogenic populations from hydrogenotrophic to acetoclastic.
