Une approche comparée des principes de proportionnalité et de subsidiarité dans la jurisprudence de la CJUE et du TJCA: la coordination-harmonisation des pluralismes juridiques régionaux à l’épreuve de l’internationalisation du droit de l’intégration

Face à la complexité de la comparaison entre les droits de l’Union européenne et de la Communauté andine caractérisés par une internationalisation pluraliste croissante, l’idée de coordination du pluriel appelle l’émergence de «macro-principes» pour penser l’universalité juridique, tant dans sa diversité que dans son unité, dans le cadre d’un système juridique supranational. Sur ce point, un constat liminaire s’impose: on ne peut aujourd’hui définir les frontières d’un droit communautaire internationalisé car elles sont floues et ouvertes. Il convient dès lors de prendre comme point de départ une étude du noyau de cette internationalisation qui passe par une comparaison de principes à vocation universelle («macro principes»). En ce sens, la proportionnalité et la subsidiarité peuvent faire l’objet d’une analyse à travers une étude comparée de la jurisprudence de la CJUE et du TJCA. Le premier principe peut ainsi être vu comme un moyen de coordination de droits communautaire tandis que le second se révèle être un outil de coordination de compétences communautaires. 

Le Travail de l’enseignant en lve à l’ecole primaire éclaire par la didactique comparée

Cette communication vise à éclairer le travail du professeur lorsqu’il enseigne l’anglais langue vivante étrangère (LVE), en France à l’école primaire. Nous tentons de comparer les différentes pratiques d’enseignement de quatre professeurs. Notre hypothèse est qu’elles varient d’un enseignant à l’autre en fonction de leur utilisation plus ou moins important de la langue maternelle (LM) dans le cours de LVE et les choix divers réalisés pour transmettre le savoir enseigné. Ces variations résultent de transpositions didactiques différentes et variées de la parole des maîtres selon leur formation, leur maîtrise de la LVE, et les approches distinctes qu’ils ont du savoir enseigné, etc

An examination of the appropriateness of the CID grammatical analysis of elicted language as an instrument to compare language acquisition in deaf children enrolled in cued speech vs. oral and signed english programs

This paper discusses a study to compare test results of the CID GAEL test among hearing impaired children who are enrolled in cued speech vs. oral vs. signed english programs.

The use of life cycle assessment to compare the environmental impact of production and feeding of conventional and genetically modified maize for broiler production in Argentina

The paper presents the methods and results of a life-cycle assessment (LCA) applied to the production of maize grain from a conventional variety compared with maize grain from a variety genetically modified to be herbicide tolerant and insect protected and to contain an enhanced oil and lysine content, and its impact when fed to broiler chickens. The findings show that there are both environmental and human health benefits of growing GM maize including lower impacts on global warming, ozone depletion, freshwater ecotoxicity and human toxicity. However, when considered in terms of the use of maize as a feed input to broiler chicken production, the benefits of the GM alternative become negligible compared to the use of conventional maize.

Les variations formelles d'un moule stylistique: rubrique, texte et image à la charnière du Merlin et de sa Suite Vulgate

Le passage du Merlin propre à sa Suite Vulgate, espace de suture entre le texte et sa continuation est dans la tradition manuscrite l'objet de variances et de déplacements. A la paix annoncée à la fin du Merlin succède en effet le conflit qui oppose le jeune roi Arthur à ses barons. Les passages de rubrication et d'entrelacement sont le lieu privilégié de variations formelles gommées par l'adoption et la reprise de moules stylistiques attendus. Ceux-ci exhibent tout en les masquant de subtiles divergences relevant de partis pris à la fois narratifs, interprétatifs et idéologiques.

New use of global warming potentials to compare cumulative and short-lived climate pollutants

Parties to the United Nations Framework Convention on Climate Change (UNFCCC) have requested guidance on common greenhouse gas metrics in accounting for Nationally determined contributions (NDCs) to emission reductions1. Metric choice can affect the relative emphasis placed on reductions of ‘cumulative climate pollutants’ such as carbon dioxide versus ‘short-lived climate pollutants’ (SLCPs), including methane and black carbon2, 3, 4, 5, 6. Here we show that the widely used 100-year global warming potential (GWP100) effectively measures the relative impact of both cumulative pollutants and SLCPs on realized warming 20–40 years after the time of emission. If the overall goal of climate policy is to limit peak warming, GWP100 therefore overstates the importance of current SLCP emissions unless stringent and immediate reductions of all climate pollutants result in temperatures nearing their peak soon after mid-century7, 8, 9, 10, which may be necessary to limit warming to “well below 2 °C” (ref. 1). The GWP100 can be used to approximately equate a one-off pulse emission of a cumulative pollutant and an indefinitely sustained change in the rate of emission of an SLCP11, 12, 13. The climate implications of traditional CO2-equivalent targets are ambiguous unless contributions from cumulative pollutants and SLCPs are specified separately.

Finite Element Analysis to Compare Complete Denture and Implant-Retained Overdentures With Different Attachment Systems

This finite element analysis compared stress distribution on complete dentures and implant-retained overdentures with different attachment systems. Four models of edentulous mandible were constructed: group A (control), complete denture; group B, overdenture retained by 2 splinted implants with bar-clip system; group C, overdenture retained by 2 unsplinted implants with o'ring system; and group D, overdenture retained by 2 splinted implants with bar-clip and 2 distally placed o'ring system. Evaluation was performed on Ansys software, with 100-N vertical load applied on central incisive teeth. The lowest maximum general stress value (in megapascal) was observed in group A (64.305) followed by groups C (119.006), D (258.650), and B (349.873). The same trend occurred it) supporting tissues with the highest stress value for cortical bone. Unsplinted implants associated with the o'ring attachment system showed the lowest maximum stress values among all overdenture groups. Furthermore, o'ring system also improved stress distribution when associated with bar-clip system.

Using error bounds to compare aggregated generalized transportation models

A comparative study of aggregation error bounds for the generalized transportation problem is presented. A priori and a posteriori error bounds were derived and a computational study was performed to (a) test the correlation between the a priori, the a posteriori, and the actual error and (b) quantify the difference of the error bounds from the actual error. Based on the results we conclude that calculating the a priori error bound can be considered as a useful strategy to select the appropriate aggregation level. The a posteriori error bound provides a good quantitative measure of the actual error.
