Synthèse de la table ronde n° 3 : "Développement agricole et réduction de la pauvreté"

Synthèse des travaux d'une table ronde organisée lors du Forum 2010 Lascaux-SPIDH (juin 2010 ; actes publiés dans l'ouvrage "De la terre aux aliments, des valeurs au droit", Inida, 2012). 3 pages.Pour ceux qui continueraient d'ignorer les rapports qui unissent l'homme à la terre, la terre à l'aliment et l'aliment à l'homme, ceux qui n'auraient encore conscience ni de leur réalité, ni de leur intensité, les récits de combats quotidiens achèveront de leur ouvrir les yeux

Synthèse de la table ronde n° 2 : "De la terre aux aliments : Qu'en est-il des droits à la terre et à l'alimentation ?"

Synthèse des travaux d'une table ronde organisée lors du Forum 2010 Lascaux-SPIDH (juin 2010 ; actes publiés dans l'ouvrage "De la terre aux aliments, des valeurs au droit", Inida, 2012). 4 pages.Le droit à l'alimentation n'échappe pas au constat selon lequel il existe souvent, sur le terrain des droits de l'Homme, un écart apparemment irréductible entre l'énoncé du principe et sa réalisation concrète. Cette distance entre formulation, d'une part, et application, d'autre part, laisse croire que ce droit n'a pas encore totalement atteint une phase de maturité juridique

Polyhydroxyalkanoate (PHA): Review of synthesis, characteristics, processing and potential applications in packaging

Polyhydroxyalkanoates (PHAs) are gaining increasing attention in the biodegradable polymer market due to their promising properties such as high biodegradability in different environments, not just in composting plants, and processing versatility. Indeed among biopolymers, these biogenic polyesters represent a potential sustainable replacement for fossil fuel-based thermoplastics. Most commercially available PHAs are obtained with pure microbial cultures grown on renewable feedstocks (i.e. glucose) under sterile conditions but recent research studies focus on the use of wastes as growth media. PHA can be extracted from the bacteria cell and then formulated and processed by extrusion for production of rigid and flexible plastic suitable not just for the most assessed medical applications but also considered for applications including packaging, moulded goods, paper coatings, non-woven fabrics, adhesives, films and performance additives. The present paper reviews the different classes of PHAs, their main properties, processing aspects, commercially available ones, as well as limitations and related improvements being researched, with specific focus on potential applications of PHAs in packaging

Extended Ordered Paired Comparison Models with Application to Football Data from German Bundesliga

A general paired comparison model for the evaluation of sports competitions is proposed. It efficiently uses the available information by allowing for ordered response categories and team-specific home advantage effects. Penalized estimation techniques are used to identify clusters of teams that share the same ability. The model is extended to include team-specific explanatory variables. It is shown that regularization techniques allow to identify the contribution of explanatory variables to the success of teams. The usefulness of the methods is demonstrated by investigating the performance and its dependence on the budget for football teams of the German Bundesliga

Autonomic symptoms in hypertensive patients with post-acute minor ischemic stroke

Background Most studies regarding autonomic dysfunction in ischemic stroke are limited to heart rate and blood pressure changes during the acute phase. However, there are few data on quantitative assessment of autonomic symptoms. We sought to assess autonomic symptoms in hypertensive ischemic stroke patients. Methods In 100 hypertensive patients (45 with symptomatic ischemic stroke (6 months after stroke onset) and 55 without stroke), we assessed autonomic symptoms using the Scale for Outcomes in Parkinson disease-Autonomic (SCOPA-AUT). Results The age (mean ± standard deviation) for the stroke group was 66 ± 12 and 63 ± 15 for the without stroke group (P = 0.8). Orthostatic hypotension occurred in 3.6% of the stroke group and 4.4% in the group without stroke. The total SCOPA-AUT score was higher in the stroke group compared with the group without stroke (P = 0.001). Domain scores for gastrointestinal (P = 0.001), urinary (P = 0.005) and cardiovascular (P = 0.001) were higher in the stroke group. No differences were found when comparing the total SCOPA-AUT scores for stroke subtypes (P = 0.168) and for lateralization (P = 0.6). SCOPA AUT scores were correlated with depression scores (P = 0.001) but not with stroke severity (P = 0.2). Conclusion Autonomic symptoms, especially, gastrointestinal, urinary and cardiovascular function, were significantly increased in hypertensive patients with minor ischemic stroke. Symptoms were associated with depression but not with the characteristic of the stroke
