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
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 ?

Using Time-Series Privileged Information for Provably Efficient Learning of Prediction Models
We study prediction of future outcomes with supervised models that use
privileged information during learning. The privileged information comprises
samples of time series observed between the baseline time of prediction and the
future outcome; this information is only available at training time which
differs from the traditional supervised learning. Our question is when using
this privileged data leads to more sample-efficient learning of models that use
only baseline data for predictions at test time. We give an algorithm for this
setting and prove that when the time series are drawn from a non-stationary
Gaussian-linear dynamical system of fixed horizon, learning with privileged
information is more efficient than learning without it. On synthetic data, we
test the limits of our algorithm and theory, both when our assumptions hold and
when they are violated. On three diverse real-world datasets, we show that our
approach is generally preferable to classical learning, particularly when data
is scarce. Finally, we relate our estimator to a distillation approach both
theoretically and empirically

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
