The role of cognitive aptitudes for explicit language learning in the relative effects of explicit and implicit feedback

Abstract: This study investigated the extent to which cognitive abilities that involve explicit cognitive processes (i.e., explicit language aptitude) are related to second language (L2) learning outcomes under two corrective feedback conditions. The study followed a pretest-posttest-delayed posttest experimental design. Forty-eight L2 learners of English carried out three oral production tasks, in which their errors on the indefinite article were treated according to their group assignment (i.e., explicit, implicit, and no-feedback). A set of controlled oral production tests was administered as pretest and posttest. Explicit language aptitude was measured using three subtests from the LLAMA Language Aptitude Test battery (Meara, 2005). Results showed that explicit language aptitude predicted immediate posttest performance only under the explicit feedback condition, suggesting that this type of feedback requires mental processes that are facilitated by explicit cognitive abilities and that its short-term effectiveness is not the same for learners with different aptitude levels.

The Passions and the Interests: Unpacking the ‘Sharing Economy’

Abstract: The phenomenal growth of "sharing economy" platforms, the increasing number of economic sectors affected and the conflicting interests among involved stakeholders explain the huge controversies around the "Sharing economy". This report aims to provide a better understanding of this phenomenon and the issues at stake. The platforms reviewed cover both factor (capital, labour) and product markets (goods and services), i.e. the entire economy (and potentially society at large), taking account of both empirical evidence and rhetorical discourses in order to remove confusion and identify both available and lacking empirical evidence. There is controversy on what the "sharing economy" is or is not. Because of its positive connotation, more companies started to claim belonging to the "sharing economy" although they actually pursue economic self-interest. The conditions of "on-demand workers" raise conflicting views, as earnings for providers are not as high as claimed and practices add to the erosion of the labour contract and to the increase of "contingent" labour. Another controversial issue is whether or not the "sharing economy’ has positive redistributive effects, for which evidence is lacking or not conclusive. Last but not least conflicts, legal disputes, and consumer protection concerns are on the rise. In this respect, the size and scope of a platform may pose very different regulatory and policy challenges which is why a conceptual clarification is needed.

Identification of distinctive interferon gene signatures in different types of myositis.

Abstract: Objective Activation of the type 1 interferon (IFN1) pathway is a prominent feature of dermatomyositis (DM) muscle and may play a role in the pathogenesis of this disease. However, the relevance of the IFN1 pathway in patients with other types of myositis such as the antisynthetase syndrome (AS), immune-mediated necrotizing myopathy (IMNM), and inclusion body myositis (IBM) is largely unknown. Moreover, the activation of the type 2 interferon (IFN2) pathway has not been comprehensively explored in myositis. In this cross-sectional study, our objective was to determine whether IFN1 and IFN2 pathways are differentially activated in different types of myositis by performing RNA sequencing on muscle biopsy samples from 119 patients with DM, IMNM, AS, or IBM and on 20 normal muscle biopsies. Methods The expression of IFN1- and IFN2-inducible genes was compared between the different groups. Results The expression of IFN1-inducible genes was high in DM, moderate in AS, and low in IMNM and IBM. In contrast, the expression of IFN2-inducible genes was high in DM, IBM, and AS but low in IMNM. The expression of IFN-inducible genes correlated with the expression of genes associated with inflammation and muscle regeneration. Of note, ISG15 expression levels alone performed as well as composite scores relying on multiple genes to monitor activation of the IFN1 pathway in myositis muscle biopsies. Conclusions IFN1 and IFN2 pathways are differentially activated in different forms of myositis. This observation may have therapeutic implications because immunosuppressive medications may preferentially target each of these pathways.

A systematic review of co-managed small-scale fisheries: Social diversity and adaptive management improve outcomes

Abstract: Small-scale fisheries are an important source of livelihoods, particularly among poor coastal populations. To improve fisheries’ condition and maximize their contribution to human welfare, co-management approaches have proliferated worldwide. In this article, we conduct a systematic review of academic literature to examine the context and attributes of co-management initiatives in small-scale fisheries, and their expected outcomes. The review suggests that a supporting legal and institutional framework facilitates the emergence of co-management, because it contributes to clarify and legitimize property rights over fish resources. It is also found that co-management delivers both ecological and social benefits: it increases the abundance and habitat of species, fish catches, actors’ participation, and the fishery’s adaptive capacity, as well as it induces processes of social learning. Furthermore, co-management is more effective if artisanal fishers and diverse stakeholders become involved through an adaptive institutional framework. However, the review also suggests that more research is needed to discern when co-management initiatives can transform pre-existing conflicts, challenge power asymmetries and distribute benefits more equitably.
