Faut-il autoriser des aides d’exploitation pérennes versées par les aéroports régionaux aux compagnies à bas coûts ?,State AIDS to low-cost airlines: Could it be worth if durable?

Les lignes directrices sur les aides publiques\, modifiées en 2014\, ouvrent désormais la possibilité d’aides à l’exploitation. Nous analysons économiquement ces mesures de soutien pour montrer qu’elles peuvent s’avérer rationnelles pour le gestionnaire d’une infrastructure aéroportuaire\, et donc être compatibles avec le critère de l’investisseur privé en économie de marché. À cette fin\, nous proposons une modélisation de l’aéroport comme une plate-forme biface\, exploitant les externalités présentes entre activités aéronautiques et activités commerciales. Nous montrons en outre qu’un lien existe entre l’intensité de l’aide et le mode de régulation ex ante des redevances aéroportuaires. Si ces dernières sont régulées par prix plafonds\, la compagnie aérienne dont le pouvoir de négociation est plus élevé pourra s’approprier la plus large part des gains de l’échange.,The guidelines on state aids\, issued in 2014\, provide simpler start-up aids rules for new routes and open the way to transitory operating aid schemes. These measures as discounts on landing or on terminal charges\, can make sense at the economic point of view and can comply with the private market investor principle. For this purpose\, we model the airport as a two-sided platform\, performing a trade-off between its aeronautical and commercial resources. Furthermore\, we put into relief the relationship between the level of the subsidy and the airport’s charges regulation. If regulation uses a price-cap mechanism\, the airline may abuse of its negotiation power to extract the main part of the surplus produced by the contract. Conversely\, a regulation based on a floor mechanism may allow to limit the capacity of the airline to extract gains and to reduce by way the level of the subsidy needed to balance the airport’s budget.

In this investigation\, we wanted: (i) to describe the attitudes and declared practices of a representative sample of French general practitioners (GPs) regarding rapid antigen diagnostic tests (RADTs) for acute pharyngitis and (ii) to identify the GPs’ characteristics associated with the use of an RADT in the last paediatric patient with pharyngitis. We performed a cross-sectional survey conducted in 2012 among a representative sample of 1\,126 self-employed GPs in France. 60.1 % of GPs declared that they used an RADT in their last patient aged between 3 and 16 years presenting with acute pharyngitis; 29.6 % of these tests were positive. Among the GPs who did not use an RADT\, 50.2 % prescribed an antibiotic\, compared to 30.5 % of prescriptions among GPs who performed an RADT\, whatever its result. In a multivariate analysis\, GPs’ age between 45 and 54 years and having attended Continuing Medical Education (CME) sessions on infectious diseases in the past year were significantly associated with an increased use of an RADT in the last patient with pharyngitis\, whereas a low volume of activity\, occasionally practising alternative medicine\, receiving pharmaceutical representatives at the practice and declaring a consultation duration \\textless15 min were factors associated with a decreased use of RADTs. The use of RADTs by GPs must be promoted; our findings could help define interventions to improve practice.

Osteoarticular sequelae of smallpox (osteomyelitis variolosa) are uncommon today. Such lesions may be observed occasionally\, however\, in countries where the disease has been endemic. Without other forms of documentation\, it is possible to suggest a diagnosis of smallpox in ancient skeletal remains and thus make a significant contribution to understanding the history of this disease. We have examined a subadult male (Skeleton 833)\, 15–17 years old at the time of death\, who presents bilateral bone manifestations of the elbows suggestive of smallpox. No other bone is similarly affected. In addition\, he presents a left sacroiliitis deemed to be a brucellar manifestation. Skeleton 833 is one of at least 730 individuals from an exhaustive excavation of a mediaeval necropolis at Pont-sur-Seine (Aube\, north-eastern France). Radiocarbon dating of his bones yields a date of between AD 1022 and 1155 (calibrated)\, thus apparently the oldest case described to date. The other published cases correspond to more recent periods with a well established historical context. We argue that this example of osteomyelitis variolosa.

Le présent article revient sur le dernier ouvrage de Thomas Piketty\, Capital et idéologie (2019). Nous commençons par inscrire l’ouvrage dans l’argument développé par l’auteur dans ses précédents ouvrages\, avant d’en souligner un certain nombre de limites. Nous questionnons d’abord la manière dont Piketty pense le capitalisme\, avant d’en venir à sa théorie de l’idéologie. Enfin\, nous tenterons de définir les contours et limites du projet de dépassement du capitalisme de Piketty\, c’est-à-dire sa vision d’une société juste\, d’un « socialisme participatif »\, développée au dernier chapitre de l’ouvrage.

Purpose: This study aims to investigate the role of two structural factors – threat level depicted on fear messages and warning size – as well as two contextual factors – repeated exposure and type of packs – on pictorial and threatening tobacco warnings’ effectiveness.Design/methodology/approachA two (warning threat level: moderate vs high) × two (coverage: 40 vs 75 per cent) × two (packaging type: plain vs branded) within-subjects experiment was carried out. Subjects were exposed three times to pictorial and threatening tobacco warnings. Both self-report and psychophysiological measurements of emotion were used.FindingsResults indicate that threat level is the most effective structural factor to influence smokers’ reactions\, while warning size has very low impact. Furthermore\, emotional arousal\, fear and disgust\, as well as attitude toward tobacco brand\, decrease after the second exposure to pictorial and threatening tobacco warnings\, but stay stable at the third exposure. However\, there is no effect of repetition on the emotional valence component\, arousal-subjective component\, on intention of quitting or of reducing cigarette consumption. Finally\, there is a negative effect of plain packs on attitude toward tobacco brand over repeated exposures\, but there is no effect of the type of packs on smokers’ emotions and intentions.Social implicationsUseful marketing social guidance\, which might help government decision-makers increase the effectiveness of smoking reduction measures\, is offered.Originality/valueFor the first time in this context\, psychophysiological and self-report measurements were combined to measure smokers’ reactions toward pictorial and threatening tobacco warnings in a repeated exposure study.

Année : 2014

In this paper\, we present a methodology to represent and measure knowledge which takes into account knowledge heterogeneity and its sectoral level theoretical and empirical implications in knowledge intensive environments. We draw on work on recombinant knowledge\, extending the approach to include the way the dynamics of technological knowledge creation evolves according to a life cycle; testing the existence of concepts such as technological paradigms; mapping the characteristics of the search process in the phases of exploration and exploitation during this technology life cycle and detecting the differences in sectoral evolution that can be explained by the properties of the knowledge base. We use European Patent Office data (1981-2005) to propose some operational metrics for the knowledge base and its evolution in two knowledge intensive sectors: biotechnology and telecommunications. Our empirical results show that there are interesting and meaningful differences across sectors\, which are linked to the different phases of the technology life cycles.
A new and innovative approach to the treatment of post-traumaticstress disorder: MDMA-assisted therapy\, historical approach andanalysis of current protocols.,Une nouvelle prise en charge innovante dans le traitement des troubles de stress post-traumatique : la thérapie assistée par MDMA\, approche historique et analyse des protocoles actuels

Cet article propose une revue de littérature sur la nature\,l’utilisation et l’efficacité clinique de la psychothérapie assistée parla MDMA pour le traitement du trouble de stress post-traumatique (TSPT). Nous décrirons d’abord la MDMA\, en soulignant ses propriétés pharmacologiques et ses effets psychologiques\, puis nous donnerons des informations historiques sur sa synthèse et les premiers usages thérapeutiques. Nous analyserons ensuite l’étude clinique de phase III\, ainsi que les évaluations cliniques à long terme de la thérapie. Les résultats mettent en évidence la grande efficacité de la thérapie assistée par la MDMA pour traiter le TSPT. L’étude de phase III montre que sur un échantillon de 90 participants\, 67 % des participants ne répondent plus aux critères de diagnostic du TSPT après la thérapie\, et que 88 % des participants ont une réduction statistiquement significative de leurs symptômes. La MDMA agit principalement au niveau des émotions et des interactions sociales\, ce qui lui confère un potentiel thérapeutique inédit ;elle facilite l’accès aux souvenirs traumatiques là où\, en temps normal\, la charge émotionnelle dépasse les capacités d’intégration et de symbolisation du sujet. Dans ce nouvel état transitoire\, le patient\,soutenu par la présence de deux thérapeutes\, peut alors revisiter ses expériences traumatiques afin de les traiter avec des outils thérapeutiques classiques. La psychothérapie assistée par la MDMA est une approche innovante qui peut être étendue bien au-delà du traitement du TSPT. Elle s’inscrit dans le domaine en plein développement des thérapies assistées par les psychédéliques\, dont la spécificité est une prise de substance ponctuelle qui se distingue de l’usage prolongé de molécules ayant des vertus thérapeutiques en psychiatrie.

Located between the deltaic plain and the subaqueous delta\, base level is one of the most important factors that affect depositional elements and the sedimentary architecture of river deltas. In this respect\, its changes are essential to reconstruct delta evolution during the Holocene. In this paper\, we study three cores drilled in the Tiber delta (Italy). Palaeoenvironmental analyses were performed and included new sedimentological data (laser grain size\, loss-on-ignition\, magnetic susceptibility)\, new data from bioindicators (ostracods and macrofauna)\, and 11 new radiocarbon dates. The three cores were analysed and replaced in a cross section between the Inner and Outer Tiber delta\, i.e.\,in the palaeolagoon and in the progradational delta plain. First\, we have mapped the Holocene transgression and progradation of the Ostia area using palaeoenvironmental age-depth modelling techniques (PADMs). PADM charts help to interpret a stratigraphic succession in a river delta. They contribute to the understanding of the links between depositional environments\, sedimentation rate\, and sea level rise and to reconstruct coastline trajectories. More precisely\, they contribute to the interpretation of the consequences of the sea level jumps dated to the 9000–8000 cal. BP period on coastal environments and help to identify progradational phases (around 4 k\, and from 2.8 to 2.6 k cal. BP). Second\, we identify indirect (freshwater bioindicators) and direct (bedload-derived facies) evidence of fluvial activity in the studied cross section. The studied deep cores indicate that at least one palaeochannel of the Tiber River was already flowing in the middle/southern part of the delta from 4 k cal. BP. Finally\, a first map of the lateral mobility of the palaeochannels of the Tiber River is proposed for the last 6 k cal. BP using the new data and a synthesis of all the data available at the scale of the delta.

Année : 2019

The duration of the VC incubation period is an important parameter for the profitability of venture capital (VC) firms. This paper uses a new database of VC-backed initial public offerings (IPOs) that are listed on French financial markets in order to highlight the importance of chief executive officer (CEO) human capital on the duration of the VC incubation period prior to the IPO. By using a duration model (Weibull model) we find that while CEOs' previous academic\, technical and managerial experiences seem not to affect the timing of an IPO\, the CEOs' entrepreneurial background is strongly negatively correlated to the duration of VC investment (it increases the hazard ratio by more than 100%) and thus fosters IPO exit. We thank the two anonymous referees for helpful comments on this work. Responsibility for any errors lies solely with the authors.

This paper describes long-term changes in human population and vegetation cover in southern France\, using summed radiocarbon probability distributions and site count data as population proxies and information from fossil pollen cores as a proxy for past land cover. Southern France is particularly well-suited to this type of study as a result of previous programmes of intensive survey work and excavation in advance of largescale construction. These make it possible to calibrate the larger scale occupation patterns in the light of the visibility issues created by the burial of archaeological sites beneath alluvial sediments. For purposes of analysis the region was divided into three biogeographical zones\, going from the Mediterranean coast to the middle Rhône valley. All the different population proxies in a given zone show broadly similar patterns of fluctuation\, though with varying levels of resolution. The long-term patterns in the different zones all show significant differences from the overall regional pattern but this is especially the case for the non-mediterranean middle Rhône area. Cluster analysis of pollen samples has been carried out to identify the main regional land cover types through the Holocene\, which are increasingly dominated by open types over time. A variety of other pollen indicators show evidence of increasing human impact through time. Measures of human impact correlate strongly with the population proxies. A series of thresholds are identified in the population-human impact trajectory that are related to other changes in the cultural sequence. The lack of independent climate data for the region means that its impact cannot currently be assessed with confidence. However\, for the later periods it is clear that the incorporation of southern France into larger regional systems played a major role in accounting for changes in land cover and settlement.

Maya economies during the colonial and modern periods is widely recorded in ethno-historical and ethnographic studies. However\, it is still difficult to determine the place of these resources in the Classic period\, especially because of poor preservation of perishable materials. We propose in this article a study of the function of lithic tools from the site of Cancuén (Guatemala)\, a site that\, because of its short chronology\, is an ideal case study for determining spatial distribution of activities within a city. For this\, we carried out experiments on the working of several species of wood and a gourd specific to Central America\, to constitute a frame of reference for traces that are appropriate to the study of pre-Columbian populations. The functional analysis of a sample of flint drills and obsidian blades from this site indicates the importance of activities related to the working of wood. It is particularly through study of the blades that we may identify these activities in contexts that are domestic as well as ceremonial\, public or for artisanal production. This analysis enables reflection on the possibility of the existence of multicrafting zones and on the type of tools used for working wood.

Phytoliths\, unlike pollen and charcoal\, are frequently conserved in sediments in the Maya lowlands but are rarely used as paleoenvironmental proxies. To better interpret and reconstruct paleoecological signatures and changes\, it is necessary to provide current analog of fossil assemblages. To do so\, we selected six modern ecosystems and differentiated them by their soil phytolith assemblages in the ancient Maya city of Naachtun (northern Petén\, Guatemala). We studied the plant communities and relative phytoliths frequencies in surface soils on 4 north–south vegetation transect\, composed of 43 quadrats. These transects cross forests and savannahs in low swampy areas North and South of the site\, and hill forest in its center\, where the city was built. Quadrats were statistically compared using multivariate analyses (CA). Six types of plant communities were characterized by their phytolith assemblages\, as well as on the presence of siliceous bioindicators such as diatoms and sponges. The D/P and LU indexes developed for these assemblages allow us to provide a precise signature of the current vegetation cover\, and identify the presence of undergrowth in forest areas\, or forest edges in savannah areas. This first modern phytolith reference for the Maya area will contribute to the development of paleoecological reconstructions for this zone.

The article presents the palaeobotanical investigations of a remarkable discovery from the Early Chalcolithic settlement of Isaiia–Balta Popii (Romania)\, a multi-layered site. The excavation of a dwelling brought to light a rather rare finding\, meaning a medium sized ceramic vessel having deposited inside two objects of burnt clay: an anthropomorphic figurine depicting pregnancy attributes and a small cone. Given the special character of the deposition\, several samples from the vessel and near it were collected for phytolith analysis. Our results highlighted a ritual plant deposition: Elongate dendritic and Blocky morphotypes suggest that cereals and probably Artemisia seem to have been used for this purpose. These plants are known\, aside from their practical uses\, as powerful symbols\, used through the ages in magic practices. All of these facts are strong arguments to interpret this find as a result of a ritual related to fertility involving both feminine and masculine symbols and plant use.
A Text Structure Indicator and two Topological Methods: New Ways for Studying Latin Historic Narratives

Éditeur : Oxford University Press
Année : 2016

Relying on the analysis of a Latin historical corpus\, our research aims to study the markers structuring literary texts in general\, and focuses on methods which\, by extension\, should be valid for any text of some length. Our basic assumption is the following: such texts include complex multilevel structures (i.e. those calling upon lexis\, semantics\, morphology\, syntax...) which function as heterogeneity indicators (progression to a new episode\, focalisation on a new point of view\, insertion of reported speech\, etc.). Additionally\, the recurrence of these structures is a factor in textual cohesion. Under certain conditions\, they function as topological ‘motifs’ marking the linear progression of the text and ensuring textual unity. We are developing new methods to detect and analyse the distributions of such ‘motifs’ and to support structural comparisons with the objective of contrastive corpus studies (contrasts between genres\, authorial styles\, etc.). Our methods are based on mathematical models (neighbourhoods\, bursts) and combine a qualitative approach with a sequential quantitative analysis in order to comprehend language in a linear fashion.
