During the All Taxa Biodiversity Inventory + Monitoring programme (ATBI+M) in the Mercantour and Alpi Marittime National Parks, our inventories of bryophytes identified 234 taxa (mosses and liverworts). This work completes the previous field campaigns, notably those of Jean-Pierre Hebrard (I MEP, Marseille) since 1965, and the ATBI bryophyte inventories in 2007. This number is based on four days of inventories in the central and peripheric territory of both National Parks, in four days in July and August 2010, together with previous data the 565 taxa known from the area still underestimate the number of species actually present. Our observations in 2010 added several new species for this area, including several rare and remarkable species such as Haplomitrium hookeri or species listed under the Habitats Directive as Buxbaumia viridis and Orthotrichum rogeri. Given the rarity of their habitats species from snow beds, large block boulders and high altitude wetlands are most remarkable. [less ▲]

We show how to represent an interval of real numbers in an abstract numeration system built on a language that is not necessarily regular. As an application, we consider representations of real numbers using the Dyck language. We also show that our framework can be applied to the rational base numeration systems. [less ▲]

Nous développons un modèle dans lequel les travailleurs peuvent avoir tendance à trop travailler quand ils sont jeunes, parce qu’ils ne peuvent ou ne veulent pas voir les conséquences que cela peut avoir sur leur santé et sur leur capacité à travailler longtemps. Pour les obliger à mieux répartir leurs efforts sur leur cycle de vie, une taxe sur les revenus du travail en début de vie et une subvention de l’épargne sont souhaitables. Si la subvention de l’épargne n’est pas disponible, la taxe optimale arbitre entre quatre considérations différentes. Nous étudions également la taxe optimale quand les individus diffèrent en productivité. [less ▲]

BACKGROUND: The Full Outline of UnResponsiveness (FOUR) has been proposed as an alternative for the Glasgow Coma Scale (GCS)/Glasgow Liege Scale (GLS) in the evaluation of consciousness in severely brain-damaged patients. We compared the FOUR and GLS/GCS in intensive care unit patients who were admitted in a comatose state. METHODS: FOUR and GLS evaluations were performed in randomized order in 176 acutely (<1 month) brain-damaged patients. GLS scores were transformed in GCS scores by removing the GLS brainstem component. Inter-rater agreement was assessed in 20% of the studied population (N = 35). A logistic regression analysis adjusted for age, and etiology was performed to assess the link between the studied scores and the outcome 3 months after injury (N = 136). RESULTS: GLS/GCS verbal component was scored 1 in 146 patients, among these 131 were intubated. We found that the inter-rater reliability was good for the FOUR score, the GLS/GCS. FOUR, GLS/GCS total scores predicted functional outcome with and without adjustment for age and etiology. 71 patients were considered as being in a vegetative/unresponsive state based on the GLS/GCS. The FOUR score identified 8 of these 71 patients as being minimally conscious given that these patients showed visual pursuit. CONCLUSIONS: The FOUR score is a valid tool with good inter-rater reliability that is comparable to the GLS/GCS in predicting outcome. It offers the advantage to be performable in intubated patients and to identify non-verbal signs of consciousness by assessing visual pursuit, and hence minimal signs of consciousness (11% in this study), not assessed by GLS/GCS scales.

Regression is a commonly used technique for describing the relationship between a response variable and one or more explanatory variables. When the response variable is a categorical variable, usual regression based on ordinary least squares should be replaced by logistic regression. Binary logistic regression should be used to perform a regression on a dichotomous response. Nominal polytomous logistic regression applies to a categorical response variable that has more than two levels with a natural ordering. And ordinal polytomous logistic regression is used when the response is a categorical variable that has more than two levels with a natural ordering. This note gives an overview of these logistic regression methods and describes three models commonly used when performing ordinal logistic regression. These models are illustrated by an example related to oak decline in the Walloon Region (Belgium). [less ▲]

Cet article apporte le regard de deux économistes sur l’activité des artistes. En réexpliquant certaines notions centrales du vocabulaire économique, ils posent explicitement trois questions : l’activité artistique est-elle une activité économique ? l’artiste est-il un entrepreneur ? et, dans ce cas, peut-on considérer qu’il est un entrepreneur social ? Si les auteurs reconnaissent que, à l’instar des entreprises sociales, de nombreux artistes ne poursuivent pas une finalité lucrative, ils recommandent toutefois de ne les considérer comme des entrepreneurs sociaux que si leurs pratiques révèlent leur souhait d’entreprendre une activité créatrice en adoptant des pratiques d’économie sociale : qualité des rapports aux publics, participation des travailleurs, choix éthique des fournisseurs, respect de l’environnement, etc [less ▲]

We use the Earth system model of intermediate complexity LOVECLIM to show the effect of coupling interactive ice sheets on the climate sensitivity of the model on a millennial time scale. We compare the response to a 2xCO2 warming scenario between fully coupled model versions including interactive Greenland and Antarctic ice sheet models and model versions with fixed ice sheets. For this purpose an ensemble of different parameter sets have been defined for LOVECLIM, covering a wide range of the model's sensitivity to greenhouse warming, while still simulating the present-day climate and the climate evolution over the last millennium within observational uncertainties. Additional freshwater fluxes from the melting ice sheets have a mitigating effect on the model's temperature response, leading to generally lower climate sensitivities of the fully coupled model versions. The mitigation is effectuated by changes in heat exchange within the ocean and at the sea-air interface, driven by freshening of the surface ocean and amplified by sea-ice-related feedbacks. The strength of the effect depends on the response of the ice sheets to the warming and on the model's climate sensitivity itself. With the ensemble approach in this study we cover a wide range of possible model responses. [less ▲]

The study looked into the current scenario of food security in Rwanda. After analysing the national level institutional and food security scenarios by using available secondary data, the researchers used primary data that have been collected from a random sample of 200 households spreading over six sectors of the Huye district by using structured interview schedule, as well using a case study of a rice cooperative in Huye district. Focus group discussions with all stake holders concerned with food security at local level enriched the data that we collected by other means. The general conclusion that emerges from the study is that in order to attain the food security at local level in Rwanda lot more to be done. Among other things, strengthening existing local institutions like farmer cooperatives, improving agricultural production technology, diversifying household income sources for better access, and genuine integration of food security concerns in the district development plans. The researchers come out with certain policy recommendations that may make the local level food security more sustainable which includes, among others, the orientation of the households well into the new modes of agricultural production and planning of household income. The need for much more local level institutional support in many areas is highlighted. On the whole, the study addressed the concerns of food access among rural households in Rwanda, and also the much wanted institutional support being exposed. [less ▲]

Analysing spatial familiarity aims to measure how places included in the life-world and in the cognitive map are familiar. Based on the study of Gale, Golledge, Halperin & Couclelis (1990), this paper explores the spatial familiarity of the inhabitants of two municipalities at the fringe of Liege (Belgium): it questions the links between the cognitive dimensions (visual, nominal, localisation) and themselves and the behavioural dimension (passing). It seeks new relevant places for the population of these urban fringe as well as the favourable factors to a good familiarity of a place. Finally, it scrutinizes the influence of people's mobility – period of residence, commuting to work, modes of transport – on spatial familiarity. [less ▲]
