This thesis is based on three essays focused on analysis of the excess liquidity in the CEMAC countries. The first one identifies the determinants of excess liquidity in developing countries by studying the case of CEMAC member countries from 1985 to 2002. The GMM estimator used has shown that the e...

International audience This paper studies optimal equity portfolios with long-term horizon under heterogeneous risk aversion levels. We focus on European stocks and empirically show that contemporaneous excess returns of semi-active strategies are negatively associated with market conditions and sen...

The Local Urbanism Plan (LUP) set, within the respect of the norms hierarchy, the using rules of the soil on his territory. This hierarchy is constituted by a number of norms and principles which kept growing more and more since it was decentralized. Even though they’re different, these norms are al...

Mademoiselle Valletta and Raymonde La maisonnette, where they lived very little, far from the street, in the trough and away, as if she had wanted to be forgotten. Everything we could see was a ground floor. Such as a doll or bedding house. Inserted between other houses plus allure copiers. Discreet...

Osteoporosis is a chronic bone disease whose prevalence increases with age. It results from an alteration in the quantity and quality of the skeleton (micro-architecture and bone mineral density) with an increased risk of fracture and co-morbidities. According to recent epidemiological studies, it i...

International audience The geology of the Republic of Djibouti, in the SE Afar Triangle, is characterized by intense tectonic and bimodal volcanic activity that began as early as 25-30 Ma. Each magmatic event was accompanied by hydrothermal activity. Mineralization generally occurs as gold-silver be...

To clarify the mechanism of inhibition of immune precipitation by early components of the classical pathway of complement, aggregation of 125I-BSA-rabbit-anti-BSA antibody complexes was performed in the presence of purified C1, C1-inactivator (C1-In) and C4. C1 delayed the rate of immune precipitati...

It is well known that there is a sharp density threshold for a random $r$-SAT formula to be satisfiable, and a similar, smaller, threshold for it to be satisfied by the pure literal rule. Also, above the satisfiability threshold, where a random formula is with high probability (whp) unsatisfiable, t...

While the investors' responses to price changes and their price forecasts are well accepted major factors contributing to large price fluctuations in financial markets, our study shows that investors' heterogeneous and dynamic risk aversion (DRA) preferences may play a more critical role in the dyna...

Specialization: Chemical Engineering Degree: Master of Science Abstract: The utilization of waste materials to generate value-added products is an appealing prospect that can generate economic and environmental benefits. When the end product of this process is itself environmentally friendly, the be...

After 13 days of weight maintenance diet (13,720 +/- 620 kJ/day, 40% fat, 15% protein, and 45% carbohydrate), five young men (71.3 +/- 7.1 kg, 181 +/- 8 cm; means +/- SD) were overfed for 9 days at 1.6 times their maintenance requirements (i.e., +8,010 kJ/day). Twenty-four-hour energy expenditure (2...

Treatment of Cl2PCH2Cl2 with CF3SiMe3 in the presence of CsF promotor gave the cesium salt Cs[((CF3)2P)2CH], which was converted to the electron-poor diphosphine (CF3)2PCH2P(CF3)2 (dfmpm) by addition of ethereal hydrogen chloride. Treatment of (C5Me5)2Os2Br4 with excess dfmpm in the presence of zinc...

National audience This intervention presents the method of analysis and the results of research into the socio-economic determinants of COVID-19 hospital and death rates, as well as the excess mortality observed in 2020 compared to previous years. It is based on a regional approach to these issues t...

‘titrebSummary’/titreb The assessment of the equilibrium unemployment rate is the subject of numerous theoretical and empirical controversy. In particular, she contrasts the Phillips Courbe supporters with those of the WS/PS models. In that article, I examine precisely the consequences for the deter...

For Henri-Pierre Jeudy today’s societies are overwhelmed. Not in the perspective of having objects or people in excess, which would be easily challenged, but in so far as today’s societies overwhelm. The profusion of speeches and images circulating in contemporary society makes the objects themselve...

For many years there has been increasing social dualisation between the large urban agglomerations that are experiencing poverty and the increasingly favoured peri-urban areas. The purpose of this article is to determine whether these average cities “follow” the same pattern of impoverishment and du...

Buscase presents the thoughts from the earliest possible interpretation, seeking to preserve the importance of thinking of this philosopher after the postage with regard mainly to its phenomenological reduction method. With this Levinas method, it is proposed that the model be deviated from the anal...

International audience The distribution of redox-sensitive elements (V, U, Mo, Mn) was studied in a sedimentary archive of the Pierre-Blanche lagoon encompassing 3500 years of sedimentation. Between 240 and 255 cm (i.e. between 0 and 350 cal. ad) in the core, there was a dark layer with no mollusc s...

Mimicry's role in the way social identities are constructed and deconstructed has considerably enriched our understanding of various power relations. However, as a spatial practice, mimicry has received scant consideration. In what ways can space itself become an object of mimicry? What strategies a...

Like other Western European countries, the Netherlands has witnessed an increase in the average age of its working population. Since a few years these changes have incited the Dutch government to review the taxation of private early retirement schemes and to push back the legal retirement age. At th...

We study an agent-based stock market model with heterogeneous agents and friction. Our model is based on that of Foellmer-Schweizer(1993): The process of a stock price in a discrete-time framework is determined by temporary equilibria via agents' excess demand functions, and the diffusion approximat...

Some metals are essential nutrients because they participate in vital cellular processes. In excess, however, they can have deleterious effects. It is therefore crucial to keep their concentration tightly controlled. In plants, nicotianamine (NA) contributes to this maintenance of equilibrium thanks...
