Oral health (OH) is indivisible from general health. Several studies have established the link between morbi-mortality, especially cardiovascular, and bad OH, particularly in the case of edentation. Regrettably, part of the population choses dental care renunciation for financial reasons. The primary care physician (PCP), as the health professionnal with the most frequent and intense contacts with the patients, plays an important role to reinforce prevention measures, OH maintenance and to detect oral pathologies. To fulfill this mission, he has to be trained to endo-buccal examination. Furthermore, both the PCP and the dentist have to proactively build an interprofessional approach to promote patients' OH.

This article introduces the term ‘the ethnographic moment’, which takes up and ‘plays’ with the long-disputed ‘ethnographic present’ in anthropology, as an indicator of changing conditions and requirements for ethnography in the context of mass media and mediation. It argues that event and debate, rather than structure and practice, have become pivotal aspects in thinking and conducting fieldwork that has to deal with the ephemeral. At the same time, it tries to show that an unquestioning acceptance of technological advancement and speed of societal change immunizes us to the thinkable absence of media and obscures analysis of lasting states of injustice and inequality, in whose (re-)production they have a stake.

Ecosystem management policies increasingly emphasize provision of multiple, as opposed to single, ecosystem services. Management for such "multifunctionality" has stimulated research into the role that biodiversity plays in providing desired rates of multiple ecosystem processes. Positive effects of biodiversity on indices of multifunctionality are consistently found, primarily because species that are redundant for one ecosystem process under a given set of environmental conditions play a distinct role under different conditions or in the provision of another ecosystem process. Here we show that the positive effects of diversity (specifically community composition) on multifunctionality indices can also arise from a statistical fallacy analogous to Simpson's paradox (where aggregating data obscures causal relationships). We manipulated soil faunal community composition in combination with nitrogen fertilization of model grassland ecosystems and repeatedly measured five ecosystem processes related to plant productivity, carbon storage, and nutrient turnover. We calculated three common multifunctionality indices based on these processes and found that the functional complexity of the soil communities had a consistent positive effect on the indices. However, only two of the five ecosystem processes also responded positively to increasing complexity, whereas the other three responded neutrally or negatively. Furthermore, none of the individual processes responded to both the complexity and the nitrogen manipulations in a manner consistent with the indices. Our data show that multifunctionality indices can obscure relationships that exist between communities and key ecosystem processes, leading us to question their use in advancing theoretical understanding-and in management decisions-about how biodiversity is related to the provision of multiple ecosystem services.

Le poète Ossip Mandelstam a été habité toute sa vie par un sentiment d’exil et de déracinement dont les causes sont diverses (« chaos judaïque » de son enfance, déménagements incessants, expérience de catastrophes historiques, etc.) : son ralliement au mouvement acméiste peut se comprendre comme une tentative de lutter contre ce sentiment au niveau de l’imaginaire. Le programme acméiste, contrairement au mouvement symboliste qui déprécie les choses d’ici bas au profit d’une réalité transcendante, peut en effet se définir comme une tentative de rendre au monde une certaine matérialité et hospitalité. Dans ce contexte, Mandelstam privilégie le motif architectural, qui lui fournit de nombreuses images de l’abri, du logement et de la protection, tout particulièrement dans son recueil intitulé Pierre. Néanmoins, si les images architecturales convoquées par Mandelstam apaisent momentanément sa soif d’un foyer, elles ne sont pas suffisantes : le poète invoque encore le pouvoir et le statut ontologique particuliers de la langue russe, seule langue capable selon lui de retrouver l’âme des choses et de faire que le poète se sente chez soi dans le monde.

Most of the policy debate surrounding the actions needed to mitigate and adapt to anthropogenic climate change has been framed by observations of the past 150 years as well as climate and sea-level projections for the twenty-first century. The focus on this 250-year window, however, obscures some of the most profound problems associated with climate change. Here, we argue that the twentieth and twenty-first centuries, a period during which the overwhelming majority of human-caused carbon emissions are likely to occur, need to be placed into a long-term context that includes the past 20 millennia, when the last Ice Age ended and human civilization developed, and the next ten millennia, over which time the projected impacts of anthropogenic climate change will grow and persist. This long-term perspective illustrates that policy decisions made in the next few years to decades will have profound impacts on global climate, ecosystems and human societies — not just for this century, but for the next ten millennia and beyond.
