A pump-probe experiment that can examine a pure charge migration on a time scale short compared to the onset of nuclear motion is discussed. The mass spectrometric studies of Schlag et al. suggest that short peptide terminated by an aromatic amino acid are particularly suitable test compounds. The pump pulse needs to ionize the molecule on a time scale short compared to the period of the electronic motion, typically sub-fs. However, ionization occurs preferentially when the electrical field of the light is maximal so that the duration of the pulse envelope can be somewhat longer. Detection by photoelectron spectrometry of the peptide cation, to produce a dication, is shown to be able to probe the electronic rearrangement. [less ▲]

This paper examines the question of sustainable consumption through the consumer’s contribution to the various dimensions of sustainability. The consumer’s participation reveals legitimacy conflicts in the process of designing new production systems. The different dimensions of sustainability can be linked to different legitimacy models. When the building of new systems entails a concerted process involving dialogue and deliberation among stakeholders from the agricultural and environmental sectors, various legitimacy principles are mobilized and confront each other through the spokespeople who represent the interests involved. This specific case concerns beef produced from the ”Gaume grassland steer,” a system that can be characterized as agroecological and territorial. The consumers who were involved contributed, through deliberative processes, to the coexistence of various legitimacy principles and stakeholder cooperation. This capacity could be linked to their multiple and fuzzy identities because their identities were shown to be flexible, changing with the institutional setting, which was sometimes consumer-oriented and sometimes territory-driven. This allowed them to act as mediators between environmentalists and farmers. To do this they had to be able to accept the limits of each legitimacy principle and contest the possibility of imposing only one principle on all the others. In so doing they helped the heterogeneous actors to reach compromises by referring to a kind of patrimonial common good. [less ▲]

In recent years, the need for educational reform in education, including university at university level has waited. Leg and Frydman (1978), Frydman and Allegaert (1986) and Vandevelde (1982) ask for many years, a "formative school" with emphasis placed on essential development for self-training, a curriculum development including long life learning. Curricula that meet these objectives have been developed and achieved. In the following pages you will find a description of main aspects of these achievements, the "Problem-based Learning". This presentation is mainly based on an analysis of the literature. [less ▲]

Problem-Based Learning is an educational method which uses health care scenarios to provide a context for learning and to elaborate knowledge through discussion. Additional expectations are to stimulate critical thinking and problem-solving skills, and to develop clinical reasoning taking into account the patient's psychosocial environment and preferences, the economic requirements as well as the best evidence from biomedical research. Appearing at the end of the 60's, it has been adopted by 10% of medical schools world-wide. PBL follows the same rules as Evidence-Based Medicine but is student-centered and provides the information-seeking skills necessary for self-directed life long learning. In this short article, we review the theoretical basis and process of PBL, emphasizing the teacher-student relationship and discussing the suggested advantages and disadvantages of this curriculum. Students in PBL programs make greater use of self-selected references and online searching. From this point of view, PBL strengthens the role of health libraries in medical education, and prepares the future physician for Evidence-Based Medicine. [less ▲]

Safe drinking water access for rural populations in developing countries remains a challenge for a sustainable develop-ment. The study aims to investigate the drinking water quality and the factors affecting this quality in the Sourou valley in Burkina Faso. A total of 135 water samples were collected in sterile glass bottles during the dry seasons 2007, 2008, and 2012 from 10 drillings and 5 wells. Fifteen physicochemical parameters and two fecal pollution indicators (Es-cherichia coli and fecal Coliforms) were monitored based on laboratory standard methods. Datas were analyzed, using the Student t’ test and XLSTAT 7.5.2 statistical software. From results obtained, water quality was related to water source and sampling period as well (p < 0.0001). 30% of drillings provided water with nitrates concentration over the World Health Organization (WHO) guideline value. High turbidity was also observed for some drillings. Moreover, 90% of drillings showed water total hardness largely over the WHO threshold value. Water from drillings were exempt of fecal pollution, contrasting with the wells one which appeared uniformly polluted with concentrations exceeding sometimes 103 and 104 CFU/100 ml for E. coli and fecal Coliforms, respectively. Field investigations showed a prefer-ence of wells as drinking water source, and that appeared related to the lack of self-management of drillings and to cul-tural considerations. Overall, this study highlighted that a regular survey of water quality, management of protection zones around drinking water sources, sensitization on water resources self-management, hygiene and health issues, and providing appropriate household disinfection methods could help advancing to reach an effective safe drinking water access for rural populations in the country.

The interannual variations of the Schyphozoan jellyfish Pelagia noctiluca is estimated by weekly measurements in the Bay of Calvi (Corsica) from 2003. The mean annual abundance reaches a dramatic maximum in 2006. The medusae appear by migration of active swarms on the shelf and at the external limit of the Bay. Degraded individuals drift as passive swarms, throughout inner side of the Bay and embayments. [less ▲]
