Empirical Evidence On The Correlation Between The Exchange Rate And Romanian Exports

Few subjects of international economics are so much exposed to heated debates as the exchange rate problem. From monetary crises and balance-of-payments adjustments to monetary zones, dealing with currency swings seems to embody any economist's worries about the rightfulness of economic models and the relevance of empirical analyses he or she has to choose. Is appreciation or depreciation good for a country's welfare? Would that answer still be valid in the long run? The unsettled character of the problem largely resides in the manifest contradiction between the firm theoretical predictions and their unconvincing empirical testing. One of the least uncontroversial tenets refers to the positive correlation between currency depreciation or devaluation (although of different origins, their effects are generally the same) and a country's current account. This paper attempts to test this prediction on the case of Romanian economy and to conclude on possible explanations of the theoretical-empirical conflict.exports, exchange rate, elasticity

A Site Evaluation Campaign for a Ground Based Atmospheric Cherenkov Telescope in Romania

Around the world, several scientific projects share the interest of a global network of small Cherenkov telescopes for monitoring observations of the brightest blazars - the DWARF network. A small, ground based, imaging atmospheric Cherenkov telescope of last generation is intended to be installed and operated in Romania as a component of the DWARF network. To prepare the construction of the observatory, two support projects have been initiated. Within the framework of these projects, we have assessed a number of possible sites where to settle the observatory. In this paper we submit a brief report on the general characteristics of the best four sites selected after the local infrastructure, the nearby facilities and the social impact criteria have been applied.Comment: 6 pages, 5 Postscript figure

Differences Between Men and Women with Total Laryngectomy

The larynx is one of the organs that is usually involved in the tumor growth in the head and neck region and it is the second site of malignant neoplasia of the respiratory tract after the lungs. It is a well-known fact that larynx cancer is more often present in male population, with a ratio of 3:1 male/female because of the higher rate of tobacco and alcohol use. The issues related to total laryngectomy are the loss of voice, swallowing rehabilitation, reeducation of breathing through the tracheostomy, psychological alterations and social pressure. Women tend to be more affected by the presence of the tracheostomy, since general physical aspect is a major concern for modern women. Also, the emotional status of women is a plays a major role for the adherence to the therapy plan. The response to total laryngectomy by men and women is similar with slight differences in physical aspect and social reinsertion

LE TELL SUBMERGÉ CHALCOLITHIQUE DE TARASCHINA ET L'ÉVOLUTION INTERNE DU DELTA DU DANUBE - REGARDS CROISÉS A PARTIR DES DONNÉES ARCHÉOLOGIQUES ET GÉO-ARCHÉOLOGIQUES

International audienceLa question de la reconnexion entre la Méditerranée et la mer Noire au début de l'Holocène est au coeur de nombreux projets de recherche. Installée une rhétorique bien huilée dérivant du mythe biblique du "déluge", la recherche a eu du mal à se départir de lieux communs fondés sur une approche déterministe des trajectoires humaines. Ainsi, les sociétés néolithiques riveraines de la Mer Noire - principalement de la zone nord pontique - soumises à un cataclysme soudain et divin se seraient trouvées devant une seule alternative : fuir ou périr ! Cette vision caricaturale voire simpliste du comportement des communautés humaines est aujourd'hui abandonnée. Il n'en reste pas moins qu'elle imprègne encore l'imaginaire collectif et journalistique. La communauté scientifique ellemême peine à se départir d'une vision déterministe de l'étude des relations qu'entretenaient les sociétés du passé avec leurs environnements. Soumises à des contraintes environnementales dont elles mesurent mal l'incidence sur leur avenir, les sociétés contemporaines développent parfois une relation irrationnelle avec leur passé en y projetant leurs angoisses fictionnelles. Questionnées par les gestionnaires ou les politiques, les communautés scientifiques ont ainsi parfois tendance à forcer le trait et à sombrer dans la caricature pour assurer le financement des recherches futures. Cet article a pour objet de présenter la manière dont on peut, dans une zone particulière comme le delta du Danube, questionner les données archéologiques et géo-archéologiques de manière à formuler de nouveaux paradigmes sur les relations entre sociétés et environnements

Wild, domestic and feral? Investigating the status of suids in the Romanian Gumelnita (5th mil. cal BC) with biogeochemistry and geometric morphometrics

International audienceIn south-eastern Romania, a prominent place was given to pigs in the Gumelniţa culture (Late Chalcolithic, second half of 5th millennium BC); as was the highly prized wild boar, one of a variety of species targeted for hunting. The wild boars’ ecological niche and the scale of pig husbandry were investigated during a stable isotope study of the Gumelniţa A2 occupations at Borduşani-Popină, Hârşova-tell and Vităneşti-Măgurice. Results from the bone collagen δ15N and δ13C analysis suggested that the wild boars did not inhabit dense forests, in any of these locations. The emerging picture is of small-scale pig husbandry involving household management: pigs being fed leftovers and/or by-products of human activities. At Vităneşti, previous work involving geometric morphometrics on suid molars evidenced, besides the two expected groups of small domestic pigs and large specimens with wild molar shape (i.e. wild boar), the presence of specimens with large size and domestic shape molars, whose relationship with the human community was unclear. Results from the combined geometric morphometric and stable isotope analyses, suggested that the large specimens with domestic molar shape lived in close proximity to the wild ecosystem. They were probably not part of the domestic stock, but belonged to a feral population and were acquired through hunting

Leveraging Transfer Learning for Robust Multimodal Positioning Systems using Smartphone Multi-sensor Data

Indoor positioning has been widely researched in recent years due to its high demand for developing localization services and its complexity in GPS-denied environments. However, the diversity of indoor spaces and temporal variation of local conditions impose the need for building specific and periodic calibrations at high cost for deployment and maintenance of these localization systems. A robust positioning solution that overcomes these challenges is yet to be available. Previous systems achieve good performance when specializing their solution to the unique characteristics of the deployment site. The drive is now to automatically model these localization solutions on the sensor data from each site with the least amount of effort. We propose to accelerate the model adaptation to new deployment sites by using transfer learning of a multimodal deep neural network architecture. We demonstrate that the required training data is drastically reduced compared to training the model from scratch, while also boosting its accuracy, due to the additional knowledge from pretraining on other sites. The resulting model is also fault-tolerant, showing good performance in missing modalities experiment. Our research opens the way toward scalable and cost efficient localization systems
