La fin des nouvelles classes : couches moyennes éclatées et société d’appareils

Le gonflement des effectifs des diplômés de l'enseignement supérieur, l'utilisation massive des savoirs scientifiques, techniques et sociaux dans le monde de la production, la croissance des grandes organisations et la multiplication de leurs niveaux hiérarchiques intermédiaires, autant d'éléments qui permettent d'expliquer le développement des couches moyennes salariées. Mais que signifie sociologiquement la croissance de ce groupe médian ? Est-elle compatible avec la représentation d'une société déchirée par le conflit de deux classes antagonistes ? Est-elle l'un des nombreux signes d'une transformation qualitative des sociétés industrielles ou plutôt le produit d'un travail idéologique et socio-politique visant à modifier le système des représentations et à occulter le conflit Capital -Travail ? Ces couches constituent-elles des fractions de la classe ouvrière et/ou de la classe dirigeante, ou fondent-elles au contraire une « nouvelle classe » qui se singulariserait non seulement par son mode de consommation, ses orientations culturelles et ses projets politiques, mais aussi par ses relations aux autres classes ?

How Much Does Money Matter in a Direct Democracy?

The fine-structure splitting of quantum confined InxGa1-x Nexcitons is investigated using polarization-sensitive photoluminescence spectroscopy. The majority of the studied emission lines exhibits mutually orthogonal fine-structure components split by 100-340 mu eV, as measured from the cleaved edge of the sample. The exciton and the biexciton reveal identical magnitudes but reversed sign of the energy splitting.Original Publication:Supaluck Amloy, Y T Chen, K F Karlsson, K H Chen, H C Hsu, C L Hsiao, L C Chen and Per-Olof Holtz, Polarization-resolved fine-structure splitting of zero-dimensional InxGa1-xN excitons, 2011, PHYSICAL REVIEW B, (83), 20, 201307.http://dx.doi.org/10.1103/PhysRevB.83.201307Copyright: American Physical Societyhttp://www.aps.org

The longitudinal-optical (LO)-phonon coupling is experimentally examined by the optical decay of various charged and neutral exciton species in single quantum dots, and the related Huang-Rhys parameters are extracted. A positive trion exhibits significantly weaker LO-phonon replicas in the photoluminescence spectrum than the neutral and negatively charged species. Model computations show that the strength of the replicas is determined by the Coulomb interactions between electrons and holes, which modify the localization of the envelope wave functions and the net charge distribution.Original Publication: Daniel Dufåker, Fredrik Karlsson, V Dimastrodonato, L O Mereni, Bo Sernelius, Per-Olof Holtz and E Pelucchi, Phonon replicas of charged and neutral exciton complexes in single quantum dots, 2010, PHYSICAL REVIEW B, (82), 20, 205421. http://dx.doi.org/10.1103/PhysRevB.82.205421 Copyright: American Physical Society http://www.aps.org/</p

Custom, resistance and politics : local experiences of improvement in early modern England

This thesis discusses popular participation in politics in early modern England and focqses on four inter-related themes that are central to our understanding of this subject: custom, improvement, public policy and resistance. These themes have been prominent in the recent historiographies either of public policy or of social relations in early modern England, but there has, as yet, been little attempt to relate these historiographies, and still less to study their central themes in the context of local experience. Full-scale case-studies of two series of enclosure riots that occurred during the 1640s, one in Duffield Frith (Derbyshire) and the other in Whittlesey (Cambridgeshire), examine closely both the micro-politics of the defence of custom within these communities and the implications ofrecent redefinitions of 'politics'. Research was undertaken not only in national but also in local archives. Indeed the two series ofriots were specifically selected because it was evident that sufficient local records had survived to permit reconstructions of the two economies upon which 'improvement' was imposed and of social relationships within the two communities. It has, moreover, been possible to recover details of various revenueraising policies implemented by the early Stuart kings or their 'ministers that have previously been studied only briefly. The discussion synthesises the contributions ofthose historians who have done 'so much in recent years to reinvigorate the historiography ofrural social and political relations, and argues that the complex rehitionships between crown policy, local resistance and popular politics can best be reconstructed through the exploration of the micro-politics of custom. It also argues that participation in politics by ordinary people went much further than many recent historians have believed. Such participation was cohflned neither to local 'horizontal' politics, nor to 'vertical' politics in terms of petitioning parliament or waging law in the central courts, but even encompassed actively choosing to vote in parliamentary elections.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

Exploring the use of social capital to support technology adoption and implementation

Information System (IS) implementations are a risky business with studies showing only a 16%-29% success rate. This research explores the use of social capital to support technology implementations. This research brings together two distinct bodies of knowledge: social network analysis (SNA) and technology acceptance models, in order to better understand the relationship between social capital and technology acceptance. The first aspect of the research looks at social network centrality and influence measures as an alternative means to measure social influence in the Unified Theory of Acceptance and Use of Technology (UTAUT) model. The social influence construct has proven to be inconsistent in past research. An individual‟s decision to adopt a new technology is influenced by their social context or the informal social network within which they work. The social capital of others influences their attitudes and decision to adopt a new technology. Social Capital, as measured through social network analysis, could be substituted for the social influence construct of the UTAUT model. Two revised UTAUT models are developed and tested. The second aspect of this research uses social capital to inform membership of a Community of Practice (CoP) to support a Finance Management System implementation in a higher education organization. SNA can be used to gain an understanding of the social network and identify individuals with high social capital. There is growing evidence that CoP support successful organizational change initiatives but it is less clear how CoP membership might be determined. SNA provides an evidence-based approach to CoP formation. The IS implementation cases described in the paper demonstrate an innovative approach to IS implementation grounded in social capital and technology acceptance research that add to the body of knowledge in both theory and practice.EThOS - Electronic Theses Online ServiceGBUnited Kingdo
