Négociation internationale sur le climat : conserver les normes du régime Rio-Kyoto

Les menaces que le changement climatique fait peser sur l'environnement global pose un problème d'action collective qui est traité dans un cadre de coopération inter étatique de type régime international, le régime climatique Rio-Kyoto.Ce papier vise à analyser les caractéristiques de ce régime, les propositions aujourd'hui discutées pour son évolution future, enfin les architectures actuellement privilégiées par deux des acteurs majeurs de la négociation internationale, les Etats-Unis et l'Union Européenne. Dans une première section nous dégagerons donc les caractéristiques principales de ce régime à travers ses éléments constitutifs qui sont en particulier un ensemble de principes et normes et de règles et procédures. Dans le cadre des règles et procédures, il est prévu de commencer de définir, à partir de 2005, de nouveaux engagements pour la suite. Les Etats doivent présenter des propositions dans ce sens. La deuxième section examinera les propositions qui sont d'ores et déjà formulées et posera la question de savoir si elles prolongent le régime de Rio-Kyoto ou s'inspirent d'autres principes et normes.Enfin la troisième section sera consacrée aux scénarios et architectures privilégiées respectivement par les Etats-Unis et par l'Europe et tentera de montrer que le respect des principes et règles du régime Rio-Kyoto est sans doute une condition de la poursuite, au plan international, d'objectifs climatiques ambitieuxchangement climatique; protocole de Kyoto; régime international; négociation

Assessing the applicability of public health intervention evaluations from one setting to another: a methodological study of the usability and usefulness of assessment tools and frameworks.

BACKGROUND: Public health interventions can be complicated, complex and context dependent, making the assessment of applicability challenging. Nevertheless, for them to be of use beyond the original study setting, they need to be generalisable to other settings and, crucially, research users need to be able to identify to which contexts it may be applicable. There are many tools with set criteria for assessing generalisability/applicability, yet few seem to be widely used and there is no consensus on which should be used, or when. This methodological study aimed to test these tools to assess how easy they were to use and how useful they appeared to be. METHODS: We identified tools from an existing review and an update of its search. References were screened on pre-specified criteria. Included tools were tested by using them to assess the applicability of a Swedish weight management intervention to the English context. Researcher assessments and reflections on the usability and utility of the tools were gathered using a standard pro-forma. RESULTS: Eleven tools were included. Their length, content, style and time required to complete varied. No tool was considered ideal for assessing applicability. Their limitations included unrealistic criteria (requiring unavailable information), a focus on implementation to the neglect of transferability (i.e. little focus on potential effectiveness in the new setting), overly broad criteria (associated with low reliability), and a lack of an explicit focus on how interventions worked (i.e. their mechanisms of action). CONCLUSION: Tools presenting criteria ready to be used may not be the best method for applicability assessments. They are likely to be either too long or incomplete, too focused on differences and fail to address elements that matter for the specific topic of interest. It is time to progress from developing lists of set criteria that are not widely used in the literature, to creating a new approach to applicability assessment. Focusing on mechanisms of action, rather than solely on characteristics, could be a useful approach, and one that remains underutilised in current tools. New approaches to assessing generalisability that evolve away from checklist style assessments need to be developed, tested, reported and discussed

Tools for faculty assessment of interdisciplinary competencies of healthcare students: an integrative review

Increasingly, interprofessional teamwork is required for the effective delivery of public health services in primary healthcare settings. Interprofessional competencies should therefore be incorporated within all health and social service education programs. Educational innovation in the development of student-led clinics (SLC) provides a unique opportunity to assess and develop such competencies. However, a suitable assessment tool is needed to appropriately assess student progression and the successful acquisition of competencies. This study adopts an integrative review methodology to locate and review existing tools utilized by teaching faculty in the assessment of interprofessional competencies in pre-licensure healthcare students. A limited number of suitable assessment tools have been reported in the literature, as highlighted by the small number of studies included. Findings identify use of existing scales such as the Interprofessional Socialization and Valuing Scale (ISVS) and the McMaster Ottawa Scale with Team Observed Structured Clinical Encounter (TOSCE) tools plus a range of other approaches, including qualitative interviews and escape rooms. Further research and consensus are needed for the development of teaching and assessment tools appropriate for healthcare students. This is particularly important in the context of interprofessional, community-partnered public health and primary healthcare SLC learning but will be of relevance to health students in a broad range of clinical learning contexts

Grounded Technology Integration: Instructional Planning Using Curriculum-Based Activity Type Taxonomies

Technological pedagogical content knowledge (tpck or tpack) – the highly practical professional educational knowledge that enables and supports technology integration – is comprised of teachers’ concurrent and interdependent curriculum content, general pedagogy, and technological understanding. Teachers’ planning – which expresses teachers’ professional knowledge (including tpack) in pragmatic ways -- is situated, contextually sensitive, routinized, and activity-based. To assist with technology integration, therefore, we suggest using what is understood from research about teachers’ knowledge and instructional planning to form an approach to curriculum-based technology integration that is predicated upon teachers combining technologically supported learning activity types selected from content-keyed activity type taxonomies. In this article, we describe this approach to curriculum-based technology integration, illustrating it with overviews of and examples from six curriculum-based learning activity types taxonomies that have been developed to date. We invite our readers to vet and use these materials, which are available on the activity types Wiki (http://activitytypes.wmwikis.net/)

Sedimentary Environment Influences the Effect of an Infaunal Suspension Feeding Bivalve on Estuarine Ecosystem Function

The suspension feeding bivalve Austrovenus stutchburyi is a key species on intertidal sandflats in New Zealand, affecting the appearance and functioning of these systems, but is susceptible to several environmental stressors including sedimentation. Previous studies into the effect of this species on ecosystem function have been restricted in space and time, limiting our ability to infer the effect of habitat change on functioning. We examined the effect of Austrovenus on benthic primary production and nutrient dynamics at two sites, one sandy, the other composed of muddy-sand to determine whether sedimentary environment alters this key species' role. At each site we established large (16 m2) plots of two types, Austrovenus addition and removal. In winter and summer we deployed light and dark benthic chambers to quantify oxygen and nutrient fluxes and measured sediment denitrification enzyme activity to assess denitrification potential. Rates of gross primary production (GPP) and ammonium uptake were significantly increased when Austrovenus was added, relative to removed, at the sandy site (GPP, 1.5 times greater in winter and summer; ammonium uptake, 8 times greater in summer; 3-factor analysis of variance (ANOVA), p<0.05). Denitrification potential was also elevated in Austrovenus addition plots at the sandy site in summer (by 1.6 times, p<0.1). In contrast, there was no effect of Austrovenus treatment on any of these variables at the muddy-sand site, and overall rates tended to be lower at the muddy-sand site, relative to the sandy site (e.g. GPP was 2.1 to 3.4 times lower in winter and summer, respectively, p<0.001). Our results suggest that the positive effects of Austrovenus on system productivity and denitrification potential is limited at a muddy-sand site compared to a sandy site, and reveal the importance of considering sedimentary environment when examining the effect of key species on ecosystem function
