Marx's critique of ideology for discourse analysis: from analysis of ideologies to social critique
2018
The notion of ideology is related to social and material reality and especially to the processes of social reproduction. Therefore, the analysis of ideology seems to fall into the domain of discourse analysis. The analysis of language and practices of signification in social contexts constitutes the basic triangle of discourse analysis. However, the Marxist concept of ideology always refers to some kind of falsity, that ultimately enables the researcher to not only analyse but also to criticize ideologies. Ideologies are always in some way false, injust or inadequate. It is at this point that discourse analysts usually raise the most serious objections as they understand truth itself as a d…
‘What’s the Moment Thingy?’– On the Emergence of Subject-Specific Knowledge in CLIL Classroom Interaction
2017
Situated in the European CLIL context where mainstream schools may opt for teaching content subjects through the medium of a foreign or second language, this paper explores secondary school physics classrooms, taught through English in Finland. The focus is on the role of classroom interaction in the emergence of subject-specific knowledge during six consecutive lessons, with particular attention to how one key concept in physics, ‘moment’, is handled. This micro-longitudinal approach shows that while the students are struggling between the everyday and the academic meanings of the word ‘moment’ throughout, there are also clear signs of progression. These signs show, for example, in student…
Spontaneous domain formation of phospholipase A2 at interfaces: fluorescence microscopy of the interaction of phospholipase A2 with mixed monolayers …
1992
Abstract Fluorescence microscopy has recently been proven to be an ideal tool to investigated the specific interaction of phospholipase A 2 with oriented substrate monolayers. Using a dual labeling technique, it could be shown that phospholipase A 2 can specifically attack and hydrolyze solid analogous l -α-DPPC domains. After a critical extent of monolayer hydrolysis the enzyme itself starts to aggregate forming regular shaped protein domains (Grainger et al. (1990) Biochim. Biophys. Acta 1023. 365–379). In order to confirm that the existence of hydrolysis products in the mononlayer is necessary for the observed aggregation of phospholipase A 2 , mixed monolayers of d - and l -α-DPPC, l -α…
AFM study of interaction forces in supported planar DPPC bilayers in the presence of general anesthetic halothane
2006
International audience; In spite of numerous investigations, the molecular mechanism of general anesthetics action is still not well understood. It has been shown that the anesthetic potency is related to the ability of an anesthetic to partition into the membrane. We have investigated changes in structure, dynamics and forces of interaction in supported dipalmitoylphosphatidylcholine (DPPC) bilayers in the presence of the general anesthetic halothane. In the present study, we measured the forces of interaction between the probe and the bilayer using an atomic force microscope. The changes in force curves as a function of anesthetic incorporation were analyzed. Force measurements were in go…
A mathematical model of exposure of nontarget Lepidoptera to Bt-maize pollen expressing Cry1Ab within Europe
2010
Genetically modified (GM) maize MON810 expresses a Cry1Ab insecticidal protein, derived from Bacillus thuringiensis ( Bt ), toxic to lepidopteran target pests such as Ostrinia nubilalis . An environmental risk to non-target Lepidoptera from this GM crop is exposure to harmful amounts of Bt -containing pollen deposited on host plants in or near MON810 fields. An 11-parameter mathematical model analysed exposure of larvae of three non-target species: the butterflies Inachis io (L.), Vanessa atalanta (L.) and moth Plutella xylostella (L.), in 11 representative maize cultivation regions in four European countries. A mortality–dose relationship was integrated with a dose–distance relationship t…
Modeling mass transfer in fracture flows with the time domain-random walk method
2019
The time domain-random walk method was developed further for simulating mass transfer in fracture flows together with matrix diffusion in surrounding porous media. Specifically, a time domain-random walk scheme was developed for numerically approximating solutions of the advection-diffusion equation when the diffusion coefficient exhibits significant spatial variation or even discontinuities. The proposed scheme relies on second-order accurate, central-difference approximations of the advective and diffusive fluxes. The scheme was verified by comparing simulated results against analytical solutions in flow configurations involving a rectangular channel connected on one side with a porous ma…
Patterns of domain-specific learning among medical undergraduate students in relation to confidence in their physiology knowledge : insights from a p…
2022
Research FocusThe promotion of domain-specific knowledge is a central goal of higher education and, in the field of medicine, it is particularly essential to promote global health. Domain-specific knowledge on its own is not exhaustive; confidence regarding the factual truth of this knowledge content is also required. An increase in both knowledge and confidence is considered a necessary prerequisite for making professional decisions in the clinical context. Especially the knowledge of human physiology is fundamental and simultaneously critical to medical decision-making. However, numerous studies have shown difficulties in understanding and misconceptions in this area of knowledge. Therefo…
La délimitation de la citoyenneté en Côte-d'Or, d'après le droit électoral de la IIe République
1997
One of the essential elements of citizenship lies in participating in politics. Il is particulary through the right to vote that man will be fully integrated into society and take part in the decisions concerning the running of the government. Adopting universal suffrage is giving an important power to men. Thus, certain rulers have tried to channel the vote by excluding citizens liable to be detrimental to them. The law of May 31, 1850 meant to eliminate the « vile multitude », according to the expression used by Thiers. And it is in particular through the study of the concrete consequences of this law that the influence of the electoral system in the definition of citizenship can be measu…
