The dimensions of social dynamics in comparative studies on higher education

2013

This article discusses social dynamics of higher education which is one of the most crucial but neglected perspectives in comparative studies of higher education. We pay attention to the importance of time, space and contexts—both geographical and socio-cultural ones—to reveal how they influence on different social dynamics in various systems of higher education. The article focuses on the national higher education system level. Theoretically we approach higher education systems from a relational perspective paying attention to dynamics created by changing relationships between different actors in cultural, geographical and historical contexts. peerReviewed

What does computer support for cooperative work mean? a structurational analysis of computer supported cooperative work

1992

Abstract Technical developments in electronic communication and computing coupled with new understanding of relationships between computers and work processes has given impetus to a significant amount of research in the area of Computer Supported Cooperative Work (CSCW). Much of this work, however, lacks strong theoretical foundations, and there is no clear definition of CSCW, the major research questions of the field, or appropriate strategies for research. In this paper we suggest Giddens' theory of structuration as a conceptual foundation for CSCW research and propose a formal definition for CSCW. We conclude by discussing seven implications of the framework for future research into: (a)…

Comment évaluer les compétences non académiques transmises aux élèves par les systèmes d'enseignement : les leçons d'une approche comparative

2014

Alors qu'une solide tradition de sociologie du curriculum s'est développée dans les pays anglo-saxons, peu de recherches empiriques concernent, en France, les contenus d'enseignement, notamment quand on s'écarte des contenus les plus académiques. L'article présente les résultats d'une recherche examinant comment, dans une variété de pays, se structurent les curricula en essayant de prendre en compte non pas les programmes mais ce qu'on peut considérer comme la visée plus globale de socialisation (éducation civique, éducation religieuse, importance de la formation professionnelle, qualité de la relation maître-élèves et accent mis sur la discipline..., et explore si des liens peuvent être ét…

INFLUENZA DEL FABRIC E DEL BONDING SULLO STATO CRITICO E SULLO SNERVAMENTO DELLE CALCARENITI

2011

The research has been devoted to the theoretical interpretation and to the modeling of the mechanical behavior of Quaternary structured soils in the Western South-Western Sicily belonging to the complex calcarenitic-sandy-clayey. After a review about the state of knowledge on the influence of textural characteristics such as fabric and bonding on mechanical behavior, this note presents the results of an experimental analysis by mean of textural identification tests, oedometer tests, triaxial and isotropic tests. For each lithotype critical state conditions and yield strength are defined.

Theorising about barriers to open e-learning systems in public administrations

2018

Abstract Barriers to the general use of e-learning technology are known across various contexts. Despite increasing efforts to clarify the range of these barriers, few efforts have been made to advance the theorising about them and, thus, to answer why and how they unfold. This study is motivated to overcome this unaddressed problem and develops a process model based on adaptive structuration theory (AST) and the punctuated socio-technical change model (PSIC). It represents how barriers unfold between actors, technology, and organisational properties in public administrations. The PaSIC model provides a new perspective on how critical incidents drive the emergence and progress of barriers t…

New solutions of preparation and activation of surfaces

2017

Organic coatings applied on the surface of cast iron pipes ensure very good chemical and anti-corrosion protection against aggressive effluents. To improve adherence between coating (epoxy) and substrate, a surface preparation is required. Among conventional processes shot blasting has emerged as the most efficient and cheapest solution for ensuring stripping while generating adapted roughness. However, as it may enhance both mechanical anchorage and chemical bonding a better understanding of these phenomena should be developed. Besides new eco-friendly alternatives were investigated.Indeed, new techniques were evaluated, i.e. laser structuring and an ultra-high pressure water jet whose maj…

Les incidences de la structuration de l'offre d'éducation

1984

International audience; Les élèves et leur famille « demandent » de l’éducation à des institutions qui « offrent » des services éducatifs. La demande d’éducation est donc médiatisée par cette offre du système scolaire qui, par ses caractéristiques et ses contraintes propres influences les choix des élèves et/ou de leur famille. Ce document tente d’explorer cette influence de l’offre en distinguant trois moments de son action : tout au long de la scolarité par son influence sur la « production de valeur scolaire » par l’élève, au moment de l’évaluation de cette « valeur scolaire », au passage entre cycles d’enseignement à travers les mécanismes d’orientation.

Technological innovation around protein and cell biochip for diagnosis: a translational research from nanoworld to patient

2009

International audience; A great challenge in biosensors and diagnosis devices relies on the way to reconstitute relevant biological mechanisms on surface of the biochips and which analytical tools are convenient to provide accurate and rapid information on the structures and function of molecules attached to this surface. A better control in the realization of biochips can be obtained in combining different complementary approaches while always keeping in mind the biological key point. Researches in CLIPP are focused towards this objective. Conception, realization and characterization of protein and cell chips are presented. We detail different strategies of materials engineering1,2,3, chem…
