RESUMO
Introduction: In 2009, the French Association de recherche en soins infirmiers (Nursing Research Association) counted fifty-four nurses holding a doctorate or working toward one. Recent developments in this area include the creation of section 92, for nursing sciences, in the National Council of Universities, making it possible for nurses in France to become professors with teaching and research responsibilities. Objectives: To update and complete the 2009 data by identifying the grades, fields of activity, and disciplines of nurses holding a doctorate or studying for one. Method: A quantitative descriptive study was carried out using an online questionnaire between December 1, 2021 and March 22, 2022. Results: the study involved 147 nurses working in France: seventy-five with a doctorate and 72 doctoral students. The majority of the respondents were women, held a supervisory position, and were working in the field of education. Among the doctorates obtained, education sciences accounted for the largest share. However, this disciple was less well represented among the doctoral candidates. Discussion: This study shows a change in the characteristics of nurses who are also doctoral candidates and in the disciplines in which they have obtained or are currently obtaining a doctorate, and an increase in the value of the degree, particularly in research, but little access to academic posts.
Introduction: En 2009, l'Association de recherche en soins infirmiers avait recensé 54 infirmières titulaires d'un doctorat et doctorantes. Parmi les intérêts récents de s'engager dans des cursus académiques figure la création, en 2019, de la section 92 « sciences infirmières ¼ au Conseil national des universités, rendant possible en France l'accès au corps d'enseignants-chercheurs à des infirmières. Objectifs: Actualiser et compléter les données de 2009 en identifiant les grades, les domaines d'activité, les disciplines des infirmières titulaires d'un doctorat ou doctorantes. Méthode: Une étude quantitative descriptive a été réalisée par un questionnaire en ligne, entre le 01/12/2021 et le 22/03/2022. Résultats: 147 participants, exerçant en France, ont été inclus, dont 75 infirmières titulaires d'un doctorat et 72 doctorantes. La majorité des répondants étaient des femmes, avaient un grade d'encadrement et exerçaient une activité professionnelle dans le domaine de la formation. Le plus grand nombre de doctorats a été obtenu en sciences de l'éducation ; cette discipline est moins représentée chez les doctorantes. Discussion: Cette étude montre une évolution des caractéristiques des infirmières doctorantes et des disciplines des doctorats obtenus ou en cours, une valorisation du diplôme notamment en recherche mais un faible accès aux fonctions académiques.

Investigating patterns and processes of parasite diversification over ancient geological periods should involve comparisons of host and parasite phylogenies in a biogeographic context. It has been shown previously that the geographical distribution of host-specific parasites of sarcopterygians was guided, from Palaeozoic to Cainozoic times, mostly by evolution and diversification of their freshwater hosts. Here, we propose phylogenies of neobatrachian frogs and their specific parasites (Platyhelminthes, Monogenea) to investigate coevolutionary processes and historical biogeography of polystomes and further discuss all the possible assumptions that may account for the early evolution of these parasites. Phylogenetic analyses of concatenated rRNA nuclear genes (18S and partial 28S) supplemented by cophylogenetic and biogeographic vicariance analyses reveal four main parasite lineages that can be ascribed to centers of diversity, namely Australia, India, Africa, and South America. In addition, the relationships among these biogeographical monophyletic groups, substantiated by molecular dating, reflect sequential origins during the breakup of Gondwana. The Australian polystome lineage may have been isolated during the first stages of the breakup, whereas the Indian lineage would have arisen after the complete separation of western and eastern Gondwanan components. Next, polystomes would have codiverged with hyloid sensu stricto and ranoid frog lineages before the completion of South American and African plate separation. Ultimately, they would have undergone an extensive diversification in South America when their ancestral host families diversified. Therefore, the presence of polystome parasites in specific anuran host clades and in discrete geographic areas reveals the importance of biogeographic vicariance in diversification processes and supports the occurrence and radiation of amphibians over ancient and recent geological periods.

The Polystomatidae is the only family within the Monogenea to parasitize sarcopterygians such as the Australian lungfish Neoceratodus poisteri and freshwater tetrapods (lissamphibians and chelonians). We present a phylogeny based on partial 18S rDNA sequences of 26 species of Polystomatidae and three taxon from the infrasubclass Oligonchoinea (= Polyopisthocotylea) obtained from the gills of teleost fishes. The basal position of the polystome from lungfish within the Polystomatidae suggests that the family arose during the evolutionary transition between actinopterygians and sarcopterygians, ca. 425 million years (Myr) ago. The monophyly of the polystomatid lineages from chelonian and lissamphibian hosts, in addition to estimates of the divergence times, indicate that polystomatids from turtles radiated ca. 191 Myr ago, following a switch from an aquatic amniote presumed to be extinct to turtles, which diversified in the Upper Triassic. Within polystomatids from lissamphibians, we observe a polytomy of four lineages, namely caudatan, neobatrachian, pelobatid and pipid polystomatid lineages, which occurred ca. 246 Myr ago according to molecular divergence-time estimates. This suggests that the first polystomatids of amphibians originated during the evolution and diversification of lissamphibian orders and suborders ca. 250 Myr ago. Finally, we report a vicariance event between two major groups of neobatrachian polystomes, which is probably linked to the separation of South America from Africa ca. 100 Myr ago.

Nucleotide sequence data from the mitochondrial 12S rRNA and cytochrome b genes were used to analyze phylogenetic relationships among sciurognath rodents. Our sample taxa included representatives of 11 sciurognath and 3 hystricognath families with two marsupial species, Didelphis virginiana and Macropus robustus, as outgroups. The dataset was analyzed using both maximum-parsimony (weighted and unweighted) and likelihood methods. Three suprafamilial groupings are strongly supported: Geomyidae + Heteromyidae (Geomyoidea), Sciuridae + Aplodontidae (Sciuroidea), and Pedetidae + Anomaluridae (Anomaluroidea). Although moderately supported, two sister group relationships were identified between Gliridae and Sciuroidea and between Castor and Geomyoidea. In contrast to previous nuclear DNA evidence, the evolutionary affinities between Ctenodactylidae and Hystricognathi (Ctenohystrica) and between Muridae and Dipodidae (Myodonta) are not supported by the mitochondrial data. Molecular divergence dates based on the combined data were estimated for suprafamilial groupings and are discussed in the light of current morphological and paleontological interpretations of rodent phylogeny.
