Most glaciers in Svalbard (High Arctic) have been retreating and thinning since the end of the Little Ice Age in the late 19th century. As a glacier retreats, it exposes new terrestrial habitats for the colonization by pioneering (micro)organisms. Here we report on the successional trajectories of cyanobacterial communities along a 100-year deglaciation gradient in the Ebba- and Hørbyebreen glacier forefields (Petunia Bay, central Svalbard). Cyanobacterial biomass and community composition were evaluated by epifluorescence microscopy and pyrosequencing of partial 16S rRNA gene sequences. Pseudanabaenales was the most abundant order in both forefields, followed by Chroococcales, Oscillatoriales, Synechococcales, Nostocales and Gloeobacterales. Succession was characterized by a decrease in phylotype richness and a marked turnover in community structure, resulting in a separation between initial (10–20 years since deglaciation), intermediate (30–50 years), and advanced (80–100 years) communities. Community turnover was explained by a combination of temporal and environmental factors, which accounted together for 46.9% of the variation in community structure. Interestingly, phylotypes associated with initial communities were related to potentially novel taxa (i.e. <97.5% similar to sequences currently available on GenBank) and sequences predominantly restricted to polar biotopes, suggesting that the initial colonization is performed by cyanobacteria from glacial and periglacial habitats. Advanced communities, on the other hand, included genotypes with a wider geographic distribution, which are likely able to establish only after the microenvironment has been modified by pioneering taxa.

Het domein van de zorg voor geïnterneerde personen kent internationaal een omslag. Naast de “criminalisering” van personen met een psychiatrische stoornis die criminele feiten begaan, ontwikkelen er zich nieuwe visies en zorgperspectieven op de kwaliteit van leven en de re-integratie in de maatschappij van zowel personen met psychische kwetsbaarheid als geïnterneerde personen.1 Tot zeer recent werden geïnterneerde personen bijna exclusief benaderd als personen die misdaden of misdrijven hebben gepleegd waar ze door hun psychische stoornis niet voor verantwoordelijk konden worden gesteld. De onderliggende logica van de aanpak was sterk geënt op een model waarbij opsluiting en isolatie van de maatschappij centraal stonden omwille van misdaad. Geïnterneerde personen werden om die reden opgesloten in een gevangenissysteem volgens een justitiële benadering. Het behandelings- en zorgperspectief raakte hierbij ondergesneeuwd. De “criminalisering” van personen met psychische stoornissen heeft in België historisch geleid tot inadequate aanpak en begeleiding van deze groep patiënten. Meerdere veroordelingen van de Belgische Staat door het Europees Hof voor de Rechten van de Mens (EHRM), overvolle gevangenissen, het gebrek aan somatische en psychiatrische gezondheidszorg binnen gevangenissen en psychiatrische annexen en aanbevelingen van het Europees Comité voor de Preventie van Foltering en Onmenselijke of Vernederende Behandeling of Bestraffing (CPT) zijn directe aanleidingen voor het Masterplan Internering (juni 2016)2 en de wet van 5 mei 2014 betreffende de internering van personen3. In deze bijdrage staan we stil bij het Masterplan Internering van 2016 en de nieuwe Interneringswet van 5 mei 2014. We proberen te duiden op welke manier in beide bronnen randvoorwaarden worden gecreëerd voor een hybride bestuursvorm in de sector. We staan kort stil bij beleidsmatige en juridische ontwikkelingen die vooraf gingen. [less ▲]

The Fair Trade and co-operative movements have much in common. This chapter aims to examine the convergences and divergences between the two fields, highlighting what they can learn from each other and how practitioners and researchers in the two areas can better collaborate. Fair trade is an innovative approach to economic development that uses a market-driven approach to exploit the growing trend in ethical, or caused-based, consumption (Nicholls & Opal 2005). Fair Trade organizations aim to re-engineer the value chains between poor producers and artisans - typically in developing countries - and their wholesale buyers such that a greater proportion of the overall rents accrue to those who provide the inputs. Put simply, Fair Trade aims to ensure that the poorest actors in a supply chain benefit from more of the overall financial value creation as a development tool. Moreover, Fair Trade reconnects producers and consumers at the point of purchase such that consumption becomes a political – or, at least, life style – choice. This chapter is structured as follows. After this introduction, the second section describes the development of Fair Trade from its historical roots to the current organizational landscape and market organization. Next there is a discussion of several key issues and challenges that have emerged as Fair Trade has become increasingly institutionalized. Then, the fourth section explores the relationship between Fair Trade and the co-operative and mutual movements. Finally, conclusions serve to sum up the chapter. [less ▲]

As an interdisciplinary research team, we seek to tackle one important question: what is the impact of metaphors on recipients? In this context, we propose to present two experiments we conducted that both aim at measuring the impact of metaphors on citizens’ perception of and opinion on two political issues, that is Belgian federalism, and the basic income. Our first experiment was based on a newspaper article from Le Soir (July 2013) in which Belgian federalism was compared to a Tetris game. 500 participants were distributed across four experimental conditions according to the type of input they were exposed to, i.e. no input, text and image, text only and image only. They were asked to perform three interrelated tasks: a free description task, a picture association task, and a questionnaire measuring their attitude towards Belgian federalism. The results suggest that the participants who had been exposed to the experimental text tended to frame their perception of Belgian federalism differently from the other participants. However, these results suggest that reading a text might have an influence on citizens’ representations, but they do not allow us to determine the specific role played by the Tetris metaphor. We therefore developed a follow-up experiment for which we produced two different versions of the experimental text: one version where the Tetris metaphor remained explicit and a second version where this metaphor was left out. This experiment was conducted among 600 participants distributed across 3 conditions: no input, metaphorical text and non-metaphorical text. This second design should allow us to further assess to what extent the Tetris-metaphor does in fact have an impact on citizens’ representations of Belgian federalism. Our second experiment aims at measuring to what extent metaphors might have an impact on citizens’ opinion on the idea of basic income. This experiment was conducted among 750 participants who were distributed across seven experimental conditions. For the first condition, there was no input at all. The second condition consisted of a simple text explaining in a few words what the basic income is. The third, fourth and fifth condition presented the same text, but with three different metaphors added to the text, comparing the basic income to respectively allowance money, a springboard and a base frame. The two final conditions presented a non-metaphorical version of the third, fourth and fifth condition. The results of both experiments will be the main topic of our contribution. [less ▲]

Whether maternal peripheral parasites constitute a representative sample of the overall population infecting the individual, remains unknown in Burkina Faso. We therefore compared Pfdhfr and Pfdhps génotypes between matched peripheral and placental isolates. PCR-restriction fragment length polymorphism (PCR-RFLP) analysis of polymorphic codons of the Pfdhfr gene (51, 59, 108 and 164) and the Pfdhps gene (437 and 540) was performed in 18 matched peripheral and placental dried blood spots of delivered women in Bobo-Dioulasso. Both Pfdhfr and Pfdhps genes were successfully genotyped in 94.4% (17/18) of the matched samples. Only 8.8% (3/34) of génotypes were of the wild type, while 20.6% (7/34), 20.6% (7/34), 23.5% (8/34) and 26.5% (9/34) comprised one, two, three and four mutations, respectively. None of the samples carried both Pfdhfr I164L and Pfdhps K540E mutations. A concordance of 82.4% was observed in matched samples for both the Pfdhfr and Pfdhps genes. Setting placental allèles as the reference, a concordance of 100% was obtained with Pfdhfr mutation S108N, Pfdhfr mutation C59R+S108N, and Pfdhfr mutation N51I+C59R +S108N, respectively. Likewise, a concordance of 85.7% was observed with the Pfdhps mutation A437G. For epidemiological purposes, peripheral blood Pfdhfr and Pfdhps genotyping is sufficient for monitoring SP resistant molecular markers in pregnant women. [less ▲]

The objective of this study was to verify the feasibility of a joint genetic evaluation system for calving ease trait of Belgian Blue (BBB) and Holstein (HOL) Walloon cattle based on data of purebred and crossbred animals. Variance components and derived genetic parameters for purebred BBB and HOL animals were estimated by using single-breed linear animal models. This analysis showed clear genetic differences between breeds. Estimates of direct and maternal heritabilities (± standard error) were 0.34 (±0.02) and 0.09 (±0.01) for BBB, respectively, but only 0.09 (±0.01) and 0.04 (±0.01) for HOL, respectively. Moreover, a significant negative genetic correlation between direct and maternal effects was obtained in both breeds: −0.46 (±0.04) for BBB and −0.29 (±0.11) for HOL. Variance components and derived genetic parameters for purebred BBB and HOL and crossbred BBB ×× HOL cattle were then estimated by using two multi-breed linear animal models: a multi-breed model based on a random regression test-day model (Model MBV), and a multi-breed model based on the random regression multi-breed model (Model MBSM). Both multi-breed models use different functions of breed proportions as random regressions, thereby enabling modelling different additive effects according to animal's breed composition. The main difference between these models is the way in which relationships between breeds are accounted for in the genetic (co)variance structure. Genetic parameters differed between single-breed and multi-breed analysis, but are similar to the literature. For BBB, estimates of direct and maternal heritabilities (±SE) were 0.45 (±0.07) and 0.08 (±0.01) by using Model MBV, and 0.45 (±0.08) and 0.09 (±0.02) for Model MBSM, respectively. For HOL, these estimates were 0.18 (±0.04) and 0.05 (±0.01) using Model MBV, and 0.16 (±0.04) and 0.05 (±0.01) for Model MBSM, respectively. Reliability gains (up to 25%) indicated that the use of crossbred data in the multi-breed models had a positive influence on the estimation of genetic merit of purebred animals. A slight re-ranking of purebred sires and maternal grandsires was observed between single-breed and multi-breed models. Moreover, both multi-breed models can be considered as quasi-equivalent models because they performed almost equally well with respect to MSE and correlations, for purebred and crossbred animals.

Locating defects in CFRP composite materials is a hot topic in nondestructive inspection (NDI). Beside classical NDI technique, such as ultrasound testing (UT), contactless techniques are actively studied. Generally manufacturers of CFRP structure incorporate artificial defects in the bulk, with different extents and depths, in order to study the performance of a specific NDI technique to detect the defect. One of the most common defects in CFRP is delamination between two layers. This is simulated by inserting teflon sheets which, like air, acts as ultrasound blocker in UT. When such reference part is used to assess NDI performance of thermography or shearography, we only observe respectively the thermal or mechanical response of teflon with respect to external loading used with these techniques. In this work, we assess other possibilities for artificial defects in CFRP matrix. For that a CFRP structure was developed and which incorporates teflon, flat-bottom holes and delamination obtained by the pull-out method. We experimentally studied the signals and we discuss the difference between the various artificial defects methods. [less ▲]

The Ourthe River, in the south-east of Belgium, has a catchment area of 3,500 km2 and is one of the main tributaries of the Meuse River. In the Ourthe, most of the flood events occur during winter and about 50% of them are due to heavy rainfall events combined to an abrupt melting of the snowpack covering the Ardennes massif during winter. This study aims to determine whether trends in extreme hydroclimatic events generating floods can be detected over the last century in Belgium, where a global warming signal can be observed. Hydroclimatic conditions favourable to floods were reconstructed over 1959- 2010 using the regional climate model MAR (“Modèle Atmosphérique Régional”) forced by the ERA-Interim/ERA-40, the ERA-20C and the NCEP/NCAR-v1 reanalyses. Extreme run-off events, which could potentially generate floods, were detected using run-off caused by precipitation events and snowpack melting from the MAR model. In the validation process, the MAR-driven temperature, precipitation and snow depth were successfully compared to daily weather data over the period 2008-2014 for 20 stations in Belgium. MAR also showed its ability to detect up to 90% of the hydroclimatic conditions which effectively generated observed floods in the Ourthe River over the period 1974- 2010. Conditions favourable to floods in the Ourthe River catchment present a negative trend over the period 1959-2010 as a result of a decrease in snow accumulation and a shortening of the snow season. This trend is expected to accelerate in a warmer climate. However, regarding the impact of the extreme precipitation events evolution on conditions favouring floods, the signal is less clear since the trends depend on the reanalysis used to force the MAR model.
