Diversity and trophic metrics based on macrophyte communities were calculated to test their pertinence to assess the ecological potential of Walloon reservoirs (Belgium). The BE-FL method (four complementary metrics) and the United Kingdom method (five metrics calculated using information on taxonomic composition and abundance of macrophyte species and groups of such species) were tested. Highly significant correlations were found between the chemical variables (o-P (mg P/l); P tot (µg P/l); NH4+ (mg N/l) DCO (mg/l) Cond (µS/cm), the phytoplankton assemblage index, Q (Padisak et al., 2006) applied for the same reservoirs (Descy et al., 2010). and trophic metric LMNI and between them and the abundance of disturbance indicators (V). Groupe of macrfophyte species metrics do not necessarily provide any direct information on the quality or degree of degradation of the environment from which the sample was taken, whereas trophic indices do.

Edible insects are considered as one of the future and sustainable sources of animal protein. Insects for food or feed could have several origins. In Asia, Africa, South America or Oceania, the diversity of edible insects is very high (approximately 2000 species) and these insects are principally collected from the wild or semi-cultivated. However, in Western countries, entomophagy promoters rely on a few numbers of insect species (approximately 10 species) and on the development of industrial farming of these insects. Effectively, insects are good candidates for sustainable farming as they possess a high conversion rate and a low environmental impact, require a reduced-size breeding space and could recycle organic industrial and/or agricultural by-products. This review will discuss the different possible origins of edible insects and the environmental impact related to these practices. Moreover, as scientific literature is very poor on this subject, suggestions on further studies in this area will be proposed. [less ▲]

Teachers are a ‘homogeneous’ socioprofessional category, which is organised and open to involvement and the promotion of a shared interest. They are an essential component of civil society on the edge or at the heart of the public sector. Whether or not they are integrated into the public sector, they share values: promotion of individuals, the emancipation and elevation of individuals, and social well-being. All of these elements are aspects which make teachers naturally open to mutual solidarity. They can fully assess the advantage of the mutual organisation as a complementary element to government social action or as a substitute for failing public authorities. They can ‘incarnate’ solidarity and reconstruct social links [less ▲]

AFM-based single-molecule force spectroscopy was used to evaluate the mechanical strength of the link between a polymer and the substrate onto which the polymer is electrografted. Poly(N-succinimidyl acrylate) was electrografted onto gold substrates and brought into contact with an aminothiol-functionalized AFM tip. Bridging of single polymer chains resulting from the strong coupling between the activated esters on the polymer and amine groups on the tip was investigated. We found that the link between the polymer and the gold substrate can withstand a force far beyond the force characteristic for physisorption on gold. [less ▲]

Background: Cannabis is the most commonly used illicit drug among teenagers and depression is one of the most common psychopathologies in adolescence. The specific symptom of depressive mood is present in 30% to 40% of adolescents in regular school settings. Links between cannabis use and depression have been highlighted, especially in adolescence. But questions remain about the strength of the association between lifetime cannabis use, depressive mood and anxiety, and about the mechanism underpinning the link. Aim: The aim of this study was to clarify the relationship between depressive mood and lifetime cannabis use in adolescents, particularly through the mediating role of anxiety and cannabis use effect expectancies, and the moderating role of peer cannabis use. Methods: A questionnaire was administered to 1,246 Belgian teenagers aged 16–17 years. ANOVA, chi-square, logistic regressions and mediation/moderation analyses were carried out to model lifetime cannabis use. Results: Depressive mood was positively correlated with lifetime cannabis use. Social anxiety, trait-anxiety and cognitive impairment effect expectancies mediated the effect of depression on lifetime cannabis use. The direct effect of depression on lifetime cannabis use increased when mediators were introduced into the relation, revealing their suppressive effects. The number of peer cannabis users moderated this model. Conclusion: Findings are discussed in terms of potential risk factors (depressive mood) or protective factors (anxiety and expectancies) for lifetime cannabis use, including the self-medication hypothesis.

Purpose – Fair trade organisations (FTOs) have been taken quite early as examples of Social Enterprises (SE) and have contributed to the shaping of the SE concept. The purpose of this paper is to examine more deeply the link between FTOs and SE, both at a conceptual and at an empirical level. Design/methodology/approach – First, different theoretical frameworks of SE are introduced and confront FT to each of these frameworks. The second step is an empirical study of FTOs across four European countries to illustrate and deepen the links between FT and SE, focusing on the goals and the governance structures of FTOs. Findings – All the FTOs combine in some way economic, social and sometimes also political goals. FTOs are thus coherent to the “hybrid goals” nature of SEs. FTOs' governance is also quite specific and often innovative in terms of organisational architecture and stakeholders' involvement. Some FTOs are closer to the European – participatory – approach while others are closer to US – individual – approaches. Finally, the governance structures of FTOs seem to reflect quite well their goal mix. Research limitations/implications – This paper provides a more solid basis for the often implicit link between FT and SE. Future researches could use this work to explore specific topics of the SE literature in the context of FT (e.g. stakeholders' involvement). The FT example could also be used to examine further the shifting boundaries of the SE reality. Originality/value – The originality of this paper is to apply the SE concept to a specific field and to show how, within this field, there is at the same time a diversity of organisations, reflecting the diversity of SE approaches; and a range of specific features (especially in terms of goal mix and governance) distinguishing SEs from other types of organisations.
