Les réformes du système de la santé, introduisant des objectifs d'efficience et de rentabilité inspirés de la doctrine de la Nouvelle gouvernance publique (NGOP), impactent l'organisation des hôpitaux et ses acteurs. Cette recherche étudie les conséquences de l'implémentation de la logique et des outils managériaux sur la profession d'infirmière en termes de contenu du travail et d'identité professionnelle. La reconfiguration des tâches au sein des structures hospitalières semble réduire l'autonomie de ces acteurs de terrain et affecter le sens que les infirmières donnent à leur travail. Par le prisme du pouvoir discrétionnaire, l'étude montre comment le personnel infirmier, principalement selon ses critères moraux, use de stratégies d'ajustement pour faire coïncider ses valeurs avec l'environnement professionnel. Toutefois, la disjonction entre les impératifs managériaux et les valeurs des infirmières engendre de la souffrance au travail. Dans une approche psychosociale, ce mémoire relie le mal-être des infirmières au concept de la « qualité empêchée » qui dévoile le mécanisme par lequel l'action des infirmières est privée en partie de son contenu.

The catalogue of Mesozoic radiolarian genera is a revision of all described genera with re-illustration of their type species. This project was organized under the auspices of the International Association of Radiolarian Paleontologists (Inter-Rad), and was carried out by the Mesozoic Working Group. This is the second of two contributions, this one devoted to the Jurassic-Cretaceous period. It contains 581 genera with re-illustration of their type species. This part shares 30 genera in common with the Triassic catalogue, most of which arose in the Carnian, Norian and Rhaetian. The sharp difference manifested between the Triassic fauna and the Jurassic-Cretaceous fauna is so evident that it justifies two independent catalogues. A comparable division between the Jurassic and Cretaceous could not be justified however, because of the similarity of the fauna, and by the greater number of genera crossing the Jurassic-Cretaceous boundary which is three times that for the Triassic-Jurassic boundary. A distinct characteristic of Jurassic-Cretaceous genera is the high number of nomina dubia (up to 131), contrary to the low number in the Triassic interval. This reflects, in part, the influence of Haeckelian taxonomy in earlier research on Jurassic-Cretaceous faunas prior to the application of SEM techniques. The Mesozoic Working Group has carefully reviewed and re-examined the taxonomy of all available genera, their family assignment and stratigraphic ranges. Following careful comparisons, 91 genera were declared as synonyms. The review has noted 26 homonyms which were duly notified to their corresponding authors, and were corrected previous to the publication of this catalogue. In spite of this effort, unfortunately nine homonyms still remain. Two invalid nominal genera, and two nomina nuda are also reported. The systematic revisions have validated 341 genera for the Jurassic-Cretaceous interval. At the end of this catalogue 24 additional are resented as support for those genera having a poor photographs p original illustration of the type species.

Les registres publics contiennent des informations très riches sur les administrés. Étant de plus en plus souvent informatisés et capables d'échanger des données, ces registres pourraient constituer une ressource inestimable à l'heure de mettre en place l'administration numérique. Cela ne va par contre pas sans poser des problèmes de protection des données et implique dans tous les cas la mise en place de processus de décision quant au partage de ces données, en fonction d'objectifs précis et dans un contexte donné. Dans cet article, nous proposons un cadre d'analyse qui permet d'évaluer les besoins en information pour une prestation administrative donnée, ainsi que les possibilités de partage ou les restrictions en matière de protection de la sphère privée. Public registers contain highly rich information about citizens. As these registers are, to a steadily increasing extent, digitized and designed for data-sharing purposes, they represent an invaluable resource when implementing e-government. At the same time, they raise a number of serious data protection issues that entail, at all events, establishing a decision-making process to frame the sharing of these data on the basis of specific objectives and in accordance with a particular context. In this article, I propose an analytical framework serving to assess both the informational requirements associated with a given administrative service as well as the opportunities for sharing data, coupled with privacy restrictions.

The common shrew Sorex araneus Linnaeus, 1758 is subject to intense chromosomal polymorphism. About 65 chromosome races are presently known. One of these chromosome races (the Valais race) is karyologically, morphologically, biochemically, and genetically clearly distinct from all other chromosome races of the species. Recent studies of hybrid zones between the Valais race and other chromosome races in the Swiss and French Alps add further strong evidence for the specific taxonomic status of the Valais race. Chromosomes and diagnostic protein markers reveal sharp frequency clines and strong heterozygote deficits. In one hybrid zone, the maintenance of the strong genetic differentiation of the hybridizing taxa was confirmed by a study with autosomal microsatellites indicating minimal gene flow. A microsatellite marker on the Y-chromosome showed complete absence of male mediated gene flow suggesting hybrid male sterility. To clarify the taxonomic status of this taxon, additional analyses were conducted. A morphometric analysis of the mandible indicated the Valais race is morphologically as distinct from neighbouring chromosome races of S. araneus as from other related Sorex species. In a phylogeny based on complete mitochondrial DNA cytochrome b gene sequences, the Valais race clearly appears as the sister taxon to all other races of S. araneus. Therefore, the chromosome race Valais of S. araneus herein is elevated to specific status and the name Sorex antinorii Bonaparte, 1840 is applied.

Raman spectroscopy has been used by fluid inclusionists to: 1) identify and quantitatively determine the relative abundances of gaseous species within fluid inclusions; 2) identify solid phases precipitating from, or accidentally trapped, within fluid inclusions; and 3) determine the detection limits of the C-13/C-12 ratio in the CO2 bearing phase of fluid inclusions.

Criticism of Daphne du Maurier’s popular classic Rebecca (1938) can be divided into two mainstream interpretations. On the one hand, it was traditionally marketed as a gothic romance where the hero and the heroine conquered the evil women that separated them. On the other, certain feminist critics have recently provided a very diff erent view of the story, aligning it with gothic narratives that deal with the dangers women suff er under the patriarchal control of their husbands. Th is would imply that du Maurier’s novel should not be read as a traditional romance that promotes patriarchy, as the former interpretation suggested. In this article, I propose, through a Gothic Studies and a Gender Studies reading, that villainy in this novel is not exclusively linked to gender and, therefore, the victim and abuser statuses cannot be equated to femininity and masculinity, respectively. Instead, I argue that villainy in the novel is inextricably connected to being in a powerful position within patriarchy, and that it is the desire to maintain this position and perpetuate the patriarchal system that leads the main characters (men and women) to commit acts of villainy.
