Hidden attractor and homoclinic orbit in Lorenz-like system describing convective fluid motion in rotating cavity
2015
Abstract In this paper a Lorenz-like system, describing convective fluid motion in rotating cavity, is considered. It is shown numerically that this system, like the classical Lorenz system, possesses a homoclinic trajectory and a chaotic self-excited attractor. However, for the considered system, unlike the classical Lorenz system, along with self-excited attractor a hidden attractor can be localized. Analytical-numerical localization of hidden attractor is demonstrated.
Afghanistan and the language of equality : a social contract in the making on a world-system fault
2013
The international intervention in Afghanistan started more than ten years ago. It built on new institutions according to the democratic model, complete with concepts generalized in the Western world since the 18th century, and among them the principle of equality. This model had founded the Amirs’ wished socio-political changes all along the 20th century, but ended in an on-going 30-year chaos with ever-renewed adversaries since the 1970’s. As operated in Afghanistan, tribalism and modernity – meant as an ideology, result in opposition prevaling as a social behaviour, which produces fragmentation or destruction and deals with equality demands through group honor. Consequently, traditionalis…
Ventilation workshop - a new concept
2000
The use of simulator technology to practise crisis resource management or to train standardised procedures in anaesthesia is a proved concept, although its setup in clinical practice is still in progress. To get a better understanding of the complex pathophysiological and clinical relations in the pulmonary system and the kind of alterations that could be induced by changing the ventilation of an intensive care unit patient, we modified the current concept. We created a workshop, which employs more than just the simulator training in the classical sense. During this workshop the participants attend one patient from admission to an emergency room, until discharge from an intensive care unit …
The Online Image of the Romanian Gendarmerie after the Diaspora Protest on August 10, 2018: Crisis Communication Strategies
2019
Abstract In this study we conducted a research on the Facebook page of the Romanian Gendarmerie, to understand the magnitude of the effects of the crisis this institution is facing after the Diaspora Protest ended in violence. We monitored the posts from August 10 to December 31, 2018 and analyzed the most relevant 50 comments from each post, in order to determine their character: positive, negative or neutral. In conducting this study, we started from the hypothesis that this event has affected the image of the Romanian Gendarmerie in the long time, and the crisis communication strategies used by the representatives of this institution have made a significant contribution to postponing the…
Does a Crisis Change News Habits? A Comparative Study of the Effects of COVID-19 on News Media Use in 17 European Countries
2021
Abstract: Exogenous shocks like the COVID-19 pandemic unleashes multiple fundamental questions about society beyond public health. Based on the classical concept of 'need for orientation' and the literature on the role of the media in times of crisis, we investigate to what extent the COVID-19 pandemic affected news consumption in comparative perspective. Based on a two-wave panel survey in 17 mostly European countries, our study targets the role of both legacy news brands (TV, radio, newspapers) and so-called contemporary news media (Internet-based and social media) during this global health crisis. Our results show an overall rise of news use across countries, but only for some types of n…
Freshening of the Mediterranean Salt Giant: controversies and certainties around the terminal (Upper Gypsum and Lago-Mare) phases of the Messinian Sa…
2021
The late Miocene evolution of the Mediterranean Basin is characterized by major changes in connectivity, climate and tectonic activity resulting in unprecedented environmental and ecological disruptions. During the Messinian Salinity Crisis (MSC, 5.97-5.33 Ma) this culminated in most scenarios first in the precipitation of gypsum around the Mediterranean margins (Stage 1, 5.97-5.60 Ma) and subsequently > 2 km of halite on the basin floor, which formed the so-called Mediterranean Salt Giant (Stage 2, 5.60-5.55 Ma). The final MSC Stage 3, however, was characterized by a "low-salinity crisis", when a second calcium-sulfate unit (Upper Gypsum; substage 3.1, 5.55-5.42 Ma) showing (bio)geochemica…
Ages and stratigraphical architecture of late Miocene deposits in the Lorca Basin (Betics, SE Spain): New insights for the salinity crisis in margina…
2020
International audience; Unlike most Neogene basins of the Betic Cordillera where the Salinity Crisis is dated to the Messinian, a contradictory Tortonian dating was proposed for evaporites of the Lorca Basin. As a consequence, complex structural models have been proposed in the literature to explain this discrepancy in the timing of evaporites. In order to integrate the Lorca Basin into the geological context of the western Mediterranean domain during the Late Miocene, new sedimentological and stratigraphical studies coupled with new dating were performed, which allow us to propose a Messinian age for both diatomite-bearing deposits and evaporites of the Lorca Basin. These new ages challeng…
The Impact of the Crisis on Economy and Labour Market, in the Southern European Countries. What about the 'Mediterranean Model'?
2017
This paper presents the first results of a research project developed in the last year. It aims at analysing and comparing the impact of the crisis on economy and labour market in the Southern European Countries (SECs). In the sociological and economic literature, these countries are considered similar up to the point of being included in a unique socio-economic model, named 'Mediterranean'. Starting from the evidence that the economic impact of the crisis in countries such as Greece, Italy, Portugal and Spain cause different changes in the labour market indicators, the analysis tries to test the theory of the existence of the 'Mediterranean model' in the way in which the SECs reacted to th…
Grasslands and Shrublands of the Mediterranean Region
2020
The Mediterranean Region extends to the 1.6% of the world’s land surface and more than the half of the Mediterranean-type ecosystems of the world. The remarkable species richness in the Mediterranean Region mainly originates from an exceptional habitat diversity and the presence of several natural barriers facilitating the segregation and differentiation of local taxa and biocoenoses. In this article, we deal with the habitats characterized by grasslands and shrublands that clearly show the adaptations to what could be called “the Mediterranean syndrome”, i.e., the intrazonal Mediterranean grasslands and shrublands (MG&S). The main driving forces of the adaptive radiation and high biodi…
The end of the Messinian Salinity Crisis in the western Mediterranean: insights from the carbonate platforms of south-eastern Spain.
2010
International audience; How the Messinian Salinity Crisis (MSC) ended is still a matter of intense debate. The Terminal Carbonate Complex (TCC) is a late Messinian carbonate platform system that recorded western Mediterranean hydrological changes from the final stages of evaporite deposition till the advent of Lago-Mare fresh- to brackish water conditions at the very end of Messinian times. A multidisciplinary study has been carried out in three localities in south-eastern Spain to reconstruct the history of TCC platforms and elucidate their significance in the MSC. Overall, this study provides evidence that the TCC formed following a regional 4th order water level rise and fall concomitant…
