This study focuses on preservice teacher's mentoring in a French University Graduate Schools of Teacher Education. It focuses on physical education and learning activities of middle school pupils. Photographs and videos are mobilised during post-lesson mentoring conference to help the preservice teacher (PT) to reduce the risk of injury. The data from a case study are made up of extracts from mentoring interview and self-confrontation interview analysed from a cultural-historical activity theory perspective (C.H.A.T). Results highlights the potential relevance of using 1) traces of learning activity during mentoring interactions to optimise the pedagogical design of PT’s 2) and to prevent the risks of pupils’ physical integrity. The theoretical model contributes to a global understanding of the problems arising in the collective teaching-learning activity and about modalities contributing to the joint tutoring activity independently of the disciplinary field.

Metabolomics is one of the most eminent and newly emerging omic sciences. It is a powerful tool to study metabolic changes that occur in an organism. Plants produce a wide range of metabolites and the study of these metabolites can answer a number of questions that arise in the minds of researchers. Change in the metabolites is the most important feature in a genetically modified plant or plant interactions with pests, pathogens and the environment. Plant pathogen interactions are amongst the most biochemically complex mechanisms and pose a great challenge in front of plant pathologists; metabolomics not only play a great role in deciphering these complex interactions but also the study of certain defence-related metabolic changes can be utilized in a number of ways to protect the plant from the harmful pathogens. The science of metabolomics utilizes a number of techniques to study the wide variety of metabolites. This review will give a brief about the various techniques used in metabolomics and how some of these techniques have been successfully utilized in the field of plant pathology.

The model of the creative ecosystem (Cohendet, Grandadam et Simon, 2011) shows that creative ideas can circulation between the underground and the upperground through the middleground. This is made possible through the activation of specific mechanisms, places, spaces, events and projects. However, the issue of the processes involved in their activation has been, so far, understudied. This article highlights the role of entrepreneurial activities in this activation. Our argument relies on the case of krautrock, a musical genre that has played a major role for the evolution of modern popular music from the end of the 1970's on. We argue that entrepreneurial activities, which consist in the settling of labels, as well as of rehearsal, recording and concert places, or in organizing festivals, embed an intermediation feature facilitating the circulation and diffusion of creative ideas. Furthermore, we show that this intermediation function takes different forms depending on the mechanism at stake and with the evolution of the ecosystem.
